Description

自動製パン器Automatic bread machine
 本発明は、主として一般家庭で使用される自動製パン器に関する。 The present invention relates to an automatic bread maker mainly used in general households.
 市販の家庭用自動製パン器は、パン原料を入れるパン容器をそのまま焼き型としてパンを製造する仕組みのものが一般的である(例えば、特許文献1参照)。このような自動製パン器では、まず、パン原料が入れられたパン容器が本体内の焼成室に入れられる。そして、パン容器内のパン原料がパン容器内に設けられる混練ブレードでパン生地に練り上げられる(練り工程)。その後、練り上げられたパン生地を発酵させる発酵工程が行われ、パン容器が焼き型として使用されてパンが焼き上げられる(焼成工程)。 Commercially available automatic bread maker for home use generally has a mechanism for producing bread by directly using a bread container into which bread ingredients are placed (see, for example, Patent Document 1). In such an automatic bread maker, first, a bread container in which bread ingredients are placed is placed in a baking chamber in the main body. And the bread raw material in a bread container is kneaded into bread dough with the kneading blade provided in a bread container (kneading process). Thereafter, a fermentation process for fermenting the kneaded bread dough is performed, and the bread container is used as a baking mold to bake the bread (baking process).
 このような自動製パン器を用いてパンの製造が行われる場合、これまでは、パン原料として、小麦や米などの穀物を製粉した粉(小麦粉、米粉等)や、そのような製粉した粉に各種の補助原料が混ぜられたミックス粉が必要とされた。しかしながら、一般家庭においては、米粒に代表されるように、粉の形態ではなく粒の形態で穀物が所持されることがある。このために、自動製パン器が穀物粒から直接パンを製造する仕組みを有すれば、非常に便利である。このようなことを念頭において、本出願人らは、穀物粒を出発原料としてパンを製造するパンの製造方法を開発している(特許文献2参照)。 When bread is manufactured using such an automatic bread maker, so far, flour (wheat flour, rice flour, etc.) or flour such as wheat or rice is used as the raw material for bread. It was necessary to have a mixed powder in which various auxiliary materials were mixed. However, in general households, as represented by rice grains, grains are sometimes held in the form of grains instead of in the form of flour. For this reason, it would be very convenient if the automatic bread maker had a mechanism for producing bread directly from grains. With this in mind, the present applicants have developed a bread production method for producing bread using cereal grains as a starting material (see Patent Document 2).
 このパンの製造方法では、まず、穀物粒と液体とが混合され、この混合物の中で粉砕ブレードが回転されて穀物粒が粉砕される(粉砕工程)。そして、粉砕工程を経て得られたペースト状の粉砕粉を含むパン原料が、混練ブレードを用いてパン生地に練り上げられる(練り工程)。その後、練り上げられたパン生地を発酵させる発酵工程が行われ、続いてパンを焼き上げる焼成工程が行われる。 In this bread manufacturing method, first, cereal grains and liquid are mixed, and the crushed blade is rotated in this mixture to pulverize the cereal grains (grinding step). And the bread raw material containing the paste-form ground powder obtained through the grinding process is kneaded into bread dough using a kneading blade (kneading process). Thereafter, a fermentation process for fermenting the kneaded bread dough is performed, followed by a baking process for baking the bread.

 本出願人らは、上述の穀物粒を出発原料としてパンを製造する方法を実行可能な、新しい仕組みを備えた自動製パン器の開発に取り組んでいる。この新しい仕組みを備えた自動製パン器の構成として、本出願人らは、例えば本体内に設けられる焼成室に収容されるパン容器内で上述の粉砕工程から焼成工程までが実行可能な構成のものを考えている。更に具体的には、本出願人らは、パン容器の底部に設けられる回転軸を回転させることで、粉砕ブレード及び混練ブレードが回転可能に設けられ、粉砕機能と混練機能とを適宜発揮させることが可能な構成の自動製パン器を検討している。 The applicants are working on the development of an automatic bread maker equipped with a new mechanism capable of executing the above-described method for producing bread using the grain as a starting material. As a configuration of an automatic bread maker equipped with this new mechanism, the applicants have a configuration capable of performing the above-described crushing process to baking process in a bread container housed in a baking chamber provided in the main body, for example. Thinking about things. More specifically, the present applicants rotate the rotating shaft provided at the bottom of the bread container so that the grinding blade and the kneading blade are rotatably provided so that the grinding function and the kneading function can be exhibited appropriately. We are studying an automatic bread maker that can be configured.
 ところで、穀物粒を出発原料としてパンを製造する自動製パン器では、穀物粒の粉砕が不十分であると、不出来なパンが製造されやすい。穀物粒を粉砕する粉砕工程の時間が長くされることで、穀物粒の粉砕レベルは、ある程度満足できるレベルとなる。しかし、このような対応は、パンが出来上がるまでに必要となる時間が長くなるために好ましくない。このため、開発中の新しい仕組みを備えた自動製パン器においては、粉砕工程における粉砕効率が良いことが求められる。 By the way, in an automatic bread maker that manufactures bread using cereal grains as a starting material, unsatisfactory bread is likely to be produced if the grains are not sufficiently pulverized. By increasing the time of the pulverization process for pulverizing the grain, the level of pulverization of the grain becomes satisfactory to some extent. However, such a countermeasure is not preferable because it takes a long time to complete bread. For this reason, an automatic bread maker equipped with a new mechanism under development is required to have good crushing efficiency in the crushing process.
 そこで、本発明の目的は、穀物粒からパンを焼き上げることを可能にする便利な仕組みを備え、効率良く穀物粒を粉砕できる自動製パン器を提供することである。 Therefore, an object of the present invention is to provide an automatic bread maker that has a convenient mechanism that enables baking of bread from cereal grains and that can efficiently grind cereal grains.
 上記目的を達成するために本発明の自動製パン器は、パン原料が投入されるパン容器を収容する収容部を有する本体と、前記パン容器の底部に設けられる回転軸と、前記本体内に設けられ、前記収容部に収容された前記パン容器の前記回転軸に回転力を与えるモータと、前記回転軸とともに回転し、前記パン容器内で穀物粒を粉砕するために使用される粉砕ブレードと、を備え、前記粉砕ブレードは、第1の切削刃を含む第1の切削部と、第2の切削刃を含む第2の切削部とを有し、前記第1の切削刃が回転する高さ位置と、前記第2の切削刃が回転する高さ位置とが、少なくとも一部において異なる。 In order to achieve the above object, an automatic bread maker of the present invention includes a main body having an accommodating portion for accommodating a bread container into which bread ingredients are charged, a rotating shaft provided at the bottom of the bread container, and the main body. A motor that is provided and applies a rotational force to the rotating shaft of the bread container accommodated in the accommodating portion, and a grinding blade that rotates together with the rotating shaft and is used to grind grain grains in the bread container; The pulverizing blade includes a first cutting portion including a first cutting blade and a second cutting portion including a second cutting blade, and the first cutting blade rotates at a high speed. The height position and the height position at which the second cutting blade rotates differ at least in part.
 本構成では、第1の切削刃が回転する高さ位置と、第2の切削刃が回転する高さ位置とが、少なくとも一部において異なる構成となっている。この場合、2つの切削刃が同一の高さ位置で回転する場合に比べて、穀物粒と切削刃との接触確率が高められる。その結果、粉砕ブレードによる穀物粒の粉砕効率が向上される。 In the present configuration, the height position at which the first cutting blade rotates and the height position at which the second cutting blade rotates are different at least in part. In this case, the contact probability between the grain and the cutting blade is increased as compared with the case where the two cutting blades rotate at the same height position. As a result, the grinding efficiency of the grain by the grinding blade is improved.
 上記構成の自動製パン器において、前記第1の切削部は、前記回転軸に直交する面に略平行に設けられ、前記第2の切削部は、前記回転軸に直交する面に対して傾いているのが好ましい。この場合の具体的な構成として、前記第1の切削部は、前記第1の切削刃の回転軌道面が前記回転軸に直交する面に略平行となるように設けられ、前記第2の切削部は、前記第2の切削刃が外周側から内周側に向けて低くなるとともに、前記第2の切削刃が設けられない側から前記第2の切削刃が設けられる側に向けて低くなる傾斜構造となっている、構成が採用されてもよい。 In the automatic bread maker configured as described above, the first cutting portion is provided substantially parallel to a surface orthogonal to the rotation axis, and the second cutting portion is inclined with respect to the surface orthogonal to the rotation axis. It is preferable. As a specific configuration in this case, the first cutting portion is provided so that a rotation track surface of the first cutting blade is substantially parallel to a surface orthogonal to the rotation axis, and the second cutting portion is provided. The portion is lowered from the outer peripheral side toward the inner peripheral side, and the portion is lowered from the side where the second cutting blade is not provided toward the side where the second cutting blade is provided. A configuration having an inclined structure may be employed.
 このように構成すると、粉砕ブレードの回転によって、粉砕対象(穀物粒)を含む液体の流れをスムーズにできるとともに、穀物粒の粉砕能力を高めることも可能である。すなわち、粉砕効率が良い自動製パン器の提供が可能になる。 With this configuration, the flow of the liquid containing the object to be crushed (cereal grains) can be made smooth by the rotation of the pulverizing blade, and the pulverizing ability of the cereal grains can be increased. That is, it is possible to provide an automatic bread maker having a high crushing efficiency.
 上記構成の自動製パン器において、前記粉砕ブレードを上から覆う第1第1のカバーが更に備えられ、前記第1のカバーにはカバー内空間とカバー外空間とを連通させる少なくとも1つの窓が形成されており、前記第1のカバーの内面には、前記粉砕ブレードが粉砕した粉砕物を前記窓の方向に誘導する少なくとも1つのリブが形成され、前記第1の切削刃が回転する高さ位置は、少なくとも一部において、前記第2の切削刃が回転する高さ位置に比べて低い、こととしてもよい。 The automatic bread maker configured as described above further includes a first first cover that covers the crushing blade from above, and the first cover has at least one window that communicates the space inside the cover and the space outside the cover. The inner surface of the first cover is formed with at least one rib for guiding the pulverized material pulverized by the pulverization blade in the direction of the window, and the height at which the first cutting blade rotates. The position may be at least partially lower than the height position at which the second cutting blade rotates.
 本構成によれば、第1のカバー内で穀物粒の粉砕が行われるので、穀物粒がパン容器外に飛散することを低減できる。また、第1のカバーに窓とリブとが設けられるために、粉砕ブレードで粉砕する穀物粒の第1のカバー内への供給と、粉砕ブレードで粉砕された粉砕粉の第1のカバー外への排出とが効率良く行える。更に、2つの切削刃が回転する高さ位置に差が設けられているために、粉砕ブレードの切削刃と穀物粒との衝突頻度が高められて粉砕効率がよい。すなわち、本構成によれば、穀物粒の粉砕効率が高められる。 According to this configuration, since the grain is crushed in the first cover, it is possible to reduce the scattering of the grain outside the bread container. In addition, since the window and the rib are provided in the first cover, supply of grain grains to be crushed by the pulverizing blade into the first cover, and pulverized powder pulverized by the pulverizing blade to the outside of the first cover. Can be efficiently discharged. Furthermore, since a difference is provided in the height position at which the two cutting blades rotate, the collision frequency between the cutting blade of the grinding blade and the grain is increased, and the grinding efficiency is good. In other words, according to this configuration, the grain grinding efficiency is increased.
 上記構成の自動製パン器において、前記第1のカバーの外面に設けられ、前記パン容器内でパン生地を練り上げるために使用される混練ブレードと、前記回転軸の回転力を前記第1のカバーに伝達するか否かを切り替えるクラッチと、を更に備え、前記粉砕ブレードは前記回転軸の回転とともに常に回転し、前記回転軸が一方向に回転する場合に、前記粉砕ブレードの前記第1の切削刃及び前記第2の切削刃は回転方向後方に位置し、且つ、前記クラッチによる動力伝達が行われて、前記第1のカバー及び前記混練ブレードは前記回転軸とともに回転し、前記回転軸が前記一方向と逆方向に回転する場合に、前記粉砕ブレードの前記第1の切削刃及び前記第2の切削刃は回転方向前方に位置し、且つ、前記クラッチによる動力伝達が行われず、前記第1のカバー及び前記混練ブレードは回転停止状態となる、こととしてもよい。 In the automatic bread maker configured as described above, a kneading blade provided on the outer surface of the first cover and used for kneading bread dough in the bread container, and the rotational force of the rotating shaft applied to the first cover. A clutch for switching whether to transmit or not, wherein the grinding blade always rotates with the rotation of the rotary shaft, and the first cutting blade of the grinding blade when the rotary shaft rotates in one direction. And the second cutting blade is positioned rearward in the rotational direction, and the power is transmitted by the clutch. The first cover and the kneading blade rotate together with the rotational shaft, and the rotational shaft is When rotating in the direction opposite to the direction, the first cutting blade and the second cutting blade of the grinding blade are positioned forward in the rotation direction, and power is transmitted by the clutch. The first cover and the kneading blades as a rotation stop state, it is also possible.
 本構成によれば、回転軸の回転方向の切り替えだけで、自動製パン器における粉砕機能と混練機能との切り替えが可能になるために、自動製パン器における制御動作が複雑とならない。また、粉砕工程において、第1のカバーの回転が停止しているために、穀物粒の粉砕効率が高められ易い。 本 According to this configuration, it is possible to switch between the crushing function and the kneading function in the automatic bread maker only by switching the rotation direction of the rotary shaft, so that the control operation in the automatic bread maker is not complicated. In addition, since the rotation of the first cover is stopped in the pulverizing step, the pulverization efficiency of the grain is easily increased.
 上記構成の自動製パン器において、前記第1のカバーには、前記粉砕ブレードを下から覆う第2のカバーが取り付けられ、前記第2のカバーは、内側環状部と、前記内側環状部の外側に同心円状に設けられる外側環状部と、互いに間隔を開けて配置されて前記内側環状部と前記外側環状部とを連結する複数の連結部と、を含む、こととしてもよい。 In the automatic bread maker configured as described above, a second cover that covers the grinding blade from below is attached to the first cover, and the second cover includes an inner annular portion and an outer side of the inner annular portion. And an outer annular portion provided concentrically, and a plurality of connecting portions that are spaced apart from each other and connect the inner annular portion and the outer annular portion.
 本構成によれば、第1のカバーに粉砕ブレードを下から覆う第2のカバーが取り付けられているために、パンの製造を行う前の準備作業(ブレード等の取り付け作業)やパンの製造後の作業(パンの取り出し等の作業)中に、ユーザが粉砕ブレードに触れてケガをする可能性が低減される。また、第2のカバーと粉砕ブレードとの関係について、あたかも、回転式電気かみそりの外刃と内刃との関係のようにできるので、穀物粒の効率の良い粉砕が期待できる。 According to this structure, since the 2nd cover which covers a grinding | pulverization blade from the bottom is attached to the 1st cover, after preparatory work (attachment work of a braid | blade etc.) before bread manufacture or bread manufacture During this operation (operation such as bread removal), the possibility of the user touching the grinding blade and being injured is reduced. Further, since the relationship between the second cover and the pulverizing blade can be made as if it is the relationship between the outer blade and the inner blade of a rotary electric razor, efficient grain pulverization can be expected.
 上記構成の自動製パン器において、前記パン容器内で前記回転軸に取り付けられるとともに、前記粉砕ブレードを覆う第1のカバーと、前記第1のカバーの外面側に所定範囲内だけ相対回転可能に取り付けられて、パン生地を練り上げる姿勢である折り畳み姿勢と、前記折り畳み姿勢に比べて前記第1のカバーから突き出して前記パン容器に回転を阻止される姿勢である開き姿勢との間で姿勢変更可能なパン生地練り上げ用の混練ブレードと、前記回転軸の回転力を前記カバーに伝達するか否かを切り替えるクラッチと、前記混練ブレードが前記開き姿勢となる場合に、前記混練ブレードと前記パン容器とが接触するのを防止する緩衝材と、を更に備えることとしてよい。 In the automatic bread maker having the above-described configuration, the automatic bread maker is attached to the rotating shaft in the bread container, and is relatively rotatable within a predetermined range on the outer surface side of the first cover and the first cover that covers the grinding blade. It is possible to change the posture between a folded posture that is a posture for kneading bread dough and an open posture that protrudes from the first cover and is prevented from rotating by the bread container as compared to the folded posture. A kneading blade for kneading bread dough, a clutch for switching whether or not to transmit the rotational force of the rotating shaft to the cover, and the kneading blade and the bread container are in contact when the kneading blade is in the open position. It is good also as providing the shock absorbing material which prevents doing.
 本構成では、粉砕ブレード及び混練ブレードは1つの回転軸を回転させることによって回転可能(混練ブレードの回転はカバーの回転に連動する)となっている。このために、パン容器内という広くない空間に効率良く(小スペースのみを使って)2つのブレードを配置可能である。すなわち、本構成の自動製パン器は、これ一台で、製パン工程の途中でブレード交換することなく、穀物粒からパンを焼き上げられるためにユーザにとって非常に便利である。 In this configuration, the grinding blade and the kneading blade can be rotated by rotating one rotating shaft (the rotation of the kneading blade is interlocked with the rotation of the cover). For this reason, it is possible to efficiently arrange two blades (using only a small space) in a non-wide space in the bread container. In other words, the automatic bread maker having this configuration is very convenient for the user because the bread can be baked from the grain without changing the blade in the middle of the bread making process.
 また、本構成では、穀物粒の粉砕を行う場合に混練ブレードを開き姿勢とすることによって、粉砕ブレードの回転につられてカバーが回転するのを阻止できる。このため、例えばカバー内にリブ(突出部)等を設ける構成を採用することによって、穀物粒の粉砕を効率良く行うことが可能になる。 Further, in this configuration, when the grain is pulverized, the cover can be prevented from rotating by the rotation of the pulverizing blade by opening the kneading blade. For this reason, for example, by adopting a configuration in which a rib (protrusion) or the like is provided in the cover, it becomes possible to efficiently grind the grain.
 更に、混練ブレードが開き姿勢となる場合において、混練ブレードとパン容器とが接触しない(直接触れ合わない)ようになっているために、互いが干渉して破損等が生じることがない。特に、パン容器や混練ブレードにはコーティング材(フッ素コーティング材等)が表面に塗られる場合があるが、本構成によれば、緩衝材の効果でコーティング材が剥がれるのを防止できる。また、穀物粒の粉砕時には粉砕ブレードの回転による微振動が生じる。このため、本構成で採用する緩衝材を配置しない場合には、混練ブレードとパン容器との衝突に伴って発生する音も問題となるが、本構成では緩衝材が防音機能を発揮するために、この問題を解消できる。なお、緩衝材は、混練ブレードやパン容器の表面より柔らかい部材で形成されるのが好ましい。 Furthermore, when the kneading blade is in the open posture, the kneading blade and the bread container are not in contact (not in direct contact), so that they do not interfere with each other and cause damage or the like. In particular, a coating material (fluorine coating material or the like) may be applied to the surface of a bread container or a kneading blade, but according to this configuration, it is possible to prevent the coating material from being peeled off due to the effect of the buffer material. Further, when the grain is pulverized, a slight vibration is generated due to the rotation of the pulverizing blade. For this reason, when the cushioning material employed in this configuration is not arranged, the sound generated due to the collision between the kneading blade and the pan container is also a problem, but in this configuration the cushioning material exhibits a soundproofing function. Can solve this problem. In addition, it is preferable that a buffer material is formed with a member softer than the surface of a kneading blade or a bread container.
 上記構成の自動製パン器において、前記粉砕ブレードは前記回転軸に相対回転不能に取り付けられ、前記第1のカバーは前記回転軸に相対回転可能に取り付けられ、前記クラッチは、前記混練ブレードの姿勢に連動して前記回転力を前記第1のカバーに伝達するか否かを切り替え可能に設けられ、前記回転軸が一方向に回転される場合に、前記混練ブレードが前記開き姿勢となって前記クラッチが前記第1のカバーに前記回転力の伝達を行わなくなり、前記混練ブレードの回転停止とともに前記第1のカバーの回転が止められ、前記粉砕ブレードによる穀物粒の粉砕が行われ、前記回転軸が前記一方向と逆方向に回転される場合に、前記混練ブレードが前記折り畳み姿勢となって前記クラッチが前記第1のカバーに前記回転力の伝達を行い、前記第1のカバーとともに前記混練ブレードが回転し、パン生地の練り上げが行われることとしてもよい。 In the automatic bread maker configured as described above, the crushing blade is attached to the rotating shaft so as not to rotate relative to the rotating shaft, the first cover is attached to the rotating shaft so as to be relatively rotatable, and the clutch is mounted on the kneading blade. Whether or not to transmit the rotational force to the first cover in conjunction with the rotation, and when the rotation shaft is rotated in one direction, the kneading blade is in the open posture and the The clutch does not transmit the rotational force to the first cover, the rotation of the first cover is stopped together with the rotation of the kneading blade, the grain is crushed by the grinding blade, and the rotating shaft Is rotated in the opposite direction to the one direction, the kneading blade is in the folded position and the clutch transmits the rotational force to the first cover. Wherein with the first cover rotates the kneading blades, may be elaborated in the dough takes place.
 本構成によれば、パン容器内に取り付けられる回転軸の回転方向によって2つのブレード(粉砕ブレード及び混練ブレード)を使い分けられる。そして、パン容器に取り付けられる回転軸の回転方向によって2つのブレードを使い分けられる構成を、簡単なクラッチ機構で実現可能である。このため、自動製パン器の製造コストを抑制可能である。 According to this configuration, the two blades (the pulverization blade and the kneading blade) can be used properly depending on the rotation direction of the rotation shaft attached to the bread container. And the structure which can use two blades properly by the rotation direction of the rotating shaft attached to a bread container is realizable with a simple clutch mechanism. For this reason, the manufacturing cost of an automatic bread maker can be suppressed.
 上記構成の自動製パン器において、前記緩衝材は、前記混練ブレードに配設されることとしてもよいし、前記パン容器に配設されることとしてもよい。前記緩衝材が前記混練ブレードに配設される場合において、前記緩衝材は、前記混練ブレードとは別部材を前記混練ブレードに固定したものであることとしてもよく、前記混練ブレードと一体的に設けられることとしてもよい。 In the automatic bread maker configured as described above, the cushioning material may be disposed on the kneading blade or may be disposed on the bread container. In the case where the cushioning material is disposed on the kneading blade, the cushioning material may be one in which a member different from the kneading blade is fixed to the kneading blade, and is provided integrally with the kneading blade. It may be done.
 上記構成の自動製パン器において、前記モータには、前記混練ブレードを低速回転するために設けられる第1のモータと、前記粉砕ブレードを高速回転するために設けられる第2のモータと、が含まれることとしてもよい。 In the automatic bread maker configured as described above, the motor includes a first motor provided for rotating the kneading blade at a low speed and a second motor provided for rotating the crushing blade at a high speed. It is also possible that
 粉砕工程時の粉砕ブレードの回転(高速回転)と、練り工程時の混練ブレードの回転(高トルク、低速回転)とは質の異なる回転が要求される。このために、本構成のように、各ブレードを回転させるためのモータは異なるものとするのが好ましい。 The rotation of the grinding blade during the grinding process (high-speed rotation) and the rotation of the kneading blade during the kneading process (high torque, low-speed rotation) require different rotations. For this reason, it is preferable that the motor for rotating each blade is different as in this configuration.
 本発明によると、穀物粒からパンを焼き上げることを可能にする便利な仕組みを備え、効率良く穀物粒を粉砕できる自動製パン器の提供が可能である。このため、本発明によれば、家庭でのパン製造をより身近なものとして、家庭でのパン作りが盛んになることが期待できる。 According to the present invention, it is possible to provide an automatic bread maker that has a convenient mechanism that allows baking of bread from cereal grains and that can efficiently grind the cereal grains. For this reason, according to the present invention, it is expected that home bread making will become popular by making home bread production more familiar.

In addition, the specific time, temperature, etc. which appear in this specification are illustrations to the last, and they do not limit the content of this invention.
(自動製パン器の構成)
 図1は、本実施形態の自動製パン器の外観構成を示す概略斜視図である。図1に示すように、略直方体形状に設けられる自動製パン器1の本体10(その外殻は例えば金属や合成樹脂等によって形成される)の上面の一部には、操作部20が設けられている。この操作部20は、操作キー群と、時間、操作キー群によって設定された内容、エラー等を表示する表示部と、によって構成されている。操作キー群には、例えば、スタートキー、取り消しキー、タイマーキー、予約キー、パンの製造コース(米粒を出発原料に用いてパンを製造するコース、米粉を出発原料に用いてパンを製造するコース、小麦粉を出発原料に用いてパンを製造するコース等)を選択する選択キー等が含まれる。表示部は、例えば、液晶表示パネル等によって構成される。
(Configuration of automatic bread maker)
FIG. 1 is a schematic perspective view showing an external configuration of the automatic bread maker according to the present embodiment. As shown in FIG. 1, an operation unit 20 is provided on a part of the upper surface of a main body 10 (the outer shell of which is formed of, for example, metal or synthetic resin) of an automatic bread maker 1 provided in a substantially rectangular parallelepiped shape. It has been. The operation unit 20 includes an operation key group and a display unit that displays time, contents set by the operation key group, errors, and the like. The operation key group includes, for example, a start key, a cancel key, a timer key, a reservation key, a bread manufacturing course (a course for manufacturing bread using rice grains as a starting material, a course for manufacturing bread using rice flour as a starting material) And a selection key for selecting a course for producing bread using flour as a starting material. The display unit is configured by, for example, a liquid crystal display panel.
 本体10内部には、詳細は後述するパン容器80が収容される焼成室30(本発明の収容部の一例)が設けられている。この焼成室30は、例えば板金からなる底壁30a及び4つの側壁30b(後述の図4も参照)で構成されている。焼成室30は、平面形状略矩形の箱形状で、その上面は開口している。この焼成室30は、本体10上部に設けられる蓋40によって開閉可能となっている。蓋40は、図示しない蝶番軸で本体10の背面側に取り付けられており、その蝶番軸を支点として回動することで、焼成室30の開閉が可能になっている。なお、図1は、この蓋40が開かれた状態を示している。 Inside the main body 10 is provided a baking chamber 30 (an example of a storage portion of the present invention) in which a bread container 80, which will be described later in detail, is stored. The firing chamber 30 is composed of, for example, a bottom wall 30a made of sheet metal and four side walls 30b (see also FIG. 4 described later). The baking chamber 30 has a substantially rectangular box shape in plan view, and its upper surface is open. The firing chamber 30 can be opened and closed by a lid 40 provided on the upper part of the main body 10. The lid 40 is attached to the back side of the main body 10 with a hinge shaft (not shown), and the firing chamber 30 can be opened and closed by rotating about the hinge shaft as a fulcrum. FIG. 1 shows a state where the lid 40 is opened.
 この蓋40には、焼成室30内を覗けるように、例えば耐熱ガラスからなる覗き窓41が設けられている。また、蓋40には、パン原料収納容器42が取り付けられている。このパン原料収納容器42は、パンの製造工程の途中で一部のパン原料を自動投入することを可能にしている。パン原料収納容器42は、平面形状略長方形の箱形状の容器本体42aと、容器本体42aに対して回動可能に設けられて、容器本体42aの開口を開閉する容器蓋42bとを備えている。また、パン原料収納容器42は、容器蓋42bを外面(下面)側から支えて容器本体42aの開口が閉じられた状態を維持可能であると共に、外部からの力によって動かされて容器蓋42bとの係合が解除される可動フック42cも備えている。 The lid 40 is provided with a viewing window 41 made of heat-resistant glass, for example, so that the inside of the baking chamber 30 can be seen. A bread ingredient storage container 42 is attached to the lid 40. This bread ingredient storage container 42 makes it possible to automatically feed some bread ingredients during the bread production process. The bread raw material storage container 42 includes a box-shaped container body 42a having a substantially rectangular plane shape, and a container lid 42b that is provided so as to be rotatable with respect to the container body 42a and opens and closes the opening of the container body 42a. . Further, the bread ingredient storage container 42 can support the container lid 42b from the outer surface (lower surface) side and maintain the closed state of the opening of the container body 42a, and is moved by an external force to move the container lid 42b to the container lid 42b. There is also provided a movable hook 42c for releasing the engagement.
 操作部20下部側の本体10内には自動投入用ソレノイド16(後述の図11参照)が設けられており、この自動投入用ソレノイド16が駆動すると、そのプランジャーが、蓋40に隣接する本体壁面10aに設けられる開口10bから突出するようになっている。そして、この突出したプランジャーによって可動する可動部材(図示せず)が可動フック42cを動かし、容器蓋42bと可動フック42cとの係合が外れて容器蓋42bが回動する。その結果、容器本体42aの開口が開かれた状態になる。なお、図1においては、容器本体42aの開口が開かれた状態が示されている。 An automatic closing solenoid 16 (see FIG. 11 described later) is provided in the main body 10 on the lower side of the operation unit 20, and when the automatic closing solenoid 16 is driven, the plunger is adjacent to the lid 40. It protrudes from the opening 10b provided in the wall surface 10a. Then, a movable member (not shown) movable by the protruding plunger moves the movable hook 42c, the container lid 42b and the movable hook 42c are disengaged, and the container lid 42b rotates. As a result, the opening of the container body 42a is opened. Note that FIG. 1 shows a state where the opening of the container main body 42a is opened.
 容器本体42a及び容器蓋42bは、容器内に収納される粉体パン原料(例えばグルテンやドライイースト等)が容器内に残留し難いように、アルミニウム等の金属で設けられるのが好ましい。そして、それらの内面は、シリコン系やフッ素系等のコーティング層で覆われるのが好ましく、更には凹凸がなるべく設けられず、滑らかに形成されるのが好ましい。 The container main body 42a and the container lid 42b are preferably provided with a metal such as aluminum so that powder bread materials (for example, gluten, dry yeast, etc.) stored in the container do not remain in the container. The inner surfaces thereof are preferably covered with a silicon-based or fluorine-based coating layer, and are preferably formed smoothly with as little unevenness as possible.
 また、米粒等の穀物粒を粉砕する際に発生する蒸気等が容器本体42a内に入り込むと、パン原料が容器内面に付着し易くなって好ましくない。このために、容器本体42a内に前述の蒸気等が入り込まないように、容器本体42aの開口側縁には鍔部(フランジ部)が設けられて、この鍔部と容器蓋42bとの間にはパッキン(シール部材)42dが介在するようになっている。 In addition, if steam or the like generated when pulverizing grains such as rice grains enters the container body 42a, it is not preferable because the bread material easily adheres to the inner surface of the container. For this purpose, a flange (flange) is provided on the opening side edge of the container main body 42a so that the above-described steam or the like does not enter the container main body 42a, and the container main body 42a is provided between the flange and the container lid 42b. Is provided with a packing (seal member) 42d.
 図2は、本実施形態の自動製パン器の本体内部の構成を説明するための模式図である。図2は、自動製パン器1を上側から見た場合を想定しており、図の下側が自動製パン器1の正面側、図の上側が背面側である。図2に示すように、自動製パン器1には、焼成室30の右横に練り工程で用いられる低速・高トルクタイプの混練モータ50が固定配置され、焼成室30の後ろ側に粉砕工程で用いられる高速回転タイプの粉砕モータ60が固定配置されている。混練モータ50及び粉砕モータ60はいずれも竪軸である。なお、混練モータ50は本発明の第1のモータの一例であり、粉砕モータ60は本発明の第2のモータの一例である。 FIG. 2 is a schematic diagram for explaining the internal configuration of the main body of the automatic bread maker according to the present embodiment. FIG. 2 assumes a case where the automatic bread maker 1 is viewed from above, and the lower side of the figure is the front side of the automatic bread maker 1 and the upper side of the figure is the back side. As shown in FIG. 2, in the automatic bread maker 1, a low-speed / high-torque type kneading motor 50 used in the kneading process is fixedly disposed on the right side of the baking chamber 30, and the grinding process is performed behind the baking chamber 30. The high-speed rotation type crushing motor 60 used in the above is fixedly arranged. The kneading motor 50 and the crushing motor 60 are both shafts. The kneading motor 50 is an example of the first motor of the present invention, and the crushing motor 60 is an example of the second motor of the present invention.
 混練モータ50の上面から突出する出力軸51には第1のプーリ52が固定される。この第1のプーリ52は、第1のベルト53によって、その径が第1のプーリ52よりも大きく形成されるとともに第1の回転軸54の上部側に固定される第2のプーリ55に連結されている。第1の回転軸54の下部側には、その回転中心が第1の回転軸54とほぼ同一となるように第2の回転軸57が設けられている(後述の図3A及び図3Bも参照)。なお、第1の回転軸54及び第2の回転軸57は、本体10内部に回転可能に支持されている。また、第1の回転軸54と第2の回転軸57との間には、動力伝達と動力遮断を行うクラッチ56が設けられている(後述の図3A及び図3Bも参照)。このクラッチ56の構成については後述する。 The first pulley 52 is fixed to the output shaft 51 protruding from the upper surface of the kneading motor 50. The first pulley 52 is connected by a first belt 53 to a second pulley 55 having a diameter larger than that of the first pulley 52 and fixed to the upper side of the first rotating shaft 54. Has been. A second rotating shaft 57 is provided on the lower side of the first rotating shaft 54 so that the center of rotation is substantially the same as the first rotating shaft 54 (see also FIGS. 3A and 3B described later). ). The first rotating shaft 54 and the second rotating shaft 57 are rotatably supported inside the main body 10. Further, a clutch 56 that performs power transmission and power interruption is provided between the first rotating shaft 54 and the second rotating shaft 57 (see also FIGS. 3A and 3B described later). The configuration of the clutch 56 will be described later.
 第2の回転軸57の下部側には第3のプーリ58が固定されている(後述の図3A及び図3Bも参照)。第3のプーリ58は、第2のベルト59によって、焼成室30の下部側に設けられるとともに原動軸11に固定される第1の原動軸用プーリ12(第3のプーリ58とほぼ同一の径を有する)に連結されている(後述の図3A及び図3B参照)。混練モータ50自身が低速・高トルクタイプであり、その上、第1のプーリ52の回転が第2のプーリ55によって減速回転される(例えば1/5の速度に減速される)。このため、クラッチ56が動力伝達を行う状態で混練モータ50を駆動すると、原動軸11は低速で回転する。 A third pulley 58 is fixed to the lower side of the second rotating shaft 57 (see also FIG. 3A and FIG. 3B described later). The third pulley 58 is provided on the lower side of the firing chamber 30 by the second belt 59 and is fixed to the driving shaft 11 and has a first driving shaft pulley 12 (having substantially the same diameter as the third pulley 58). (See FIGS. 3A and 3B described later). The kneading motor 50 itself is a low speed / high torque type, and the rotation of the first pulley 52 is decelerated and rotated by the second pulley 55 (for example, decelerated to 1/5 speed). For this reason, when the kneading motor 50 is driven in a state where the clutch 56 transmits power, the driving shaft 11 rotates at a low speed.
 なお、第1のプーリ52、第1のベルト53、第1の回転軸54、第2のプーリ55、クラッチ56、第2の回転軸57、第3のプーリ58、第2のベルト59、及び第1の原動軸用プーリ12で構成される動力伝達部は、以下では、第1の動力伝達部PT1と表現されることがある。 The first pulley 52, the first belt 53, the first rotating shaft 54, the second pulley 55, the clutch 56, the second rotating shaft 57, the third pulley 58, the second belt 59, and Hereinafter, the power transmission unit configured by the first driving shaft pulley 12 may be expressed as a first power transmission unit PT1.
 粉砕モータ60の下面から突出する出力軸61には、第4のプーリ62が固定されている。この第4のプーリ62は、第3のベルト63によって、原動軸11に固定される第2の原動軸用プーリ13(第1の原動軸用プーリ12より下側で固定される;後述の図3A及び図3B参照)に連結されている。第2の原動軸用プーリ13は第4のプーリ62とほぼ同一の径を有する。粉砕モータ60には高速回転可能なものが選定され、第4のプーリ62の回転は第2の原動軸用プーリ13においてほぼ同一速度で維持される。このために、粉砕モータ60の高速回転により、原動軸11は高速回転(例えば7000~8000rpm)を行う。 A fourth pulley 62 is fixed to the output shaft 61 protruding from the lower surface of the grinding motor 60. The fourth pulley 62 is fixed by a third belt 63 below the second driving shaft pulley 13 (below the first driving shaft pulley 12) fixed to the driving shaft 11; 3A and FIG. 3B). The second driving shaft pulley 13 has substantially the same diameter as the fourth pulley 62. A grinding motor 60 that can rotate at high speed is selected, and the rotation of the fourth pulley 62 is maintained at substantially the same speed in the second driving shaft pulley 13. For this purpose, the driving shaft 11 rotates at a high speed (for example, 7000 to 8000 rpm) by the high speed rotation of the grinding motor 60.
 なお、第4のプーリ62、第3のベルト63、及び第2の原動軸用プーリ13で構成される動力伝達部は、以下では、第2の動力伝達部PT2と表現されることがある。第2の動力伝達部PT2は、クラッチを有さない構成であり、粉砕モータ60の出力軸61と原動軸11とを常時動力伝達可能に連結する。 In addition, the power transmission unit including the fourth pulley 62, the third belt 63, and the second driving shaft pulley 13 may be hereinafter expressed as a second power transmission unit PT2. The second power transmission unit PT2 has a configuration that does not have a clutch, and connects the output shaft 61 of the crushing motor 60 and the driving shaft 11 so that power can be transmitted constantly.
 図3A及び図3Bは、本実施形態の自動製パン器が備える第1の動力伝達部に含まれるクラッチについて説明するための図である。図3A及び図3Bは、図2の矢印X方向に沿って見た場合を想定した図である。なお、図3Aはクラッチ56が動力遮断を行う状態を示し、図3Bはクラッチ56が動力伝達を行う状態を示す。 3A and 3B are views for explaining a clutch included in the first power transmission unit provided in the automatic bread maker of the present embodiment. 3A and 3B are diagrams assuming a case of viewing along the direction of the arrow X in FIG. 3A shows a state where the clutch 56 performs power cut-off, and FIG. 3B shows a state where the clutch 56 performs power transmission.
 図3A及び図3Bに示すように、クラッチ56は、第1のクラッチ部材561と第2のクラッチ部材562とを有する。そして、第1のクラッチ部材561に設けられる爪561aと、第2のクラッチ部材562に設けられる爪562aとが噛み合う場合(図3(b)の状態)に、クラッチ56は動力伝達を行う。また、2つの爪561a、562bが噛み合わない場合(図3Aの状態)に、クラッチ56は動力遮断を行う。すなわち、クラッチ56は噛み合いクラッチとなっている。 3A and 3B, the clutch 56 includes a first clutch member 561 and a second clutch member 562. When the claw 561a provided on the first clutch member 561 and the claw 562a provided on the second clutch member 562 are engaged with each other (the state shown in FIG. 3B), the clutch 56 transmits power. Further, when the two claws 561a and 562b are not engaged with each other (the state shown in FIG. 3A), the clutch 56 cuts off the power. That is, the clutch 56 is a meshing clutch.
 なお、本実施形態では、2つのクラッチ部材561、562のそれぞれには、周方向(第1のクラッチ部材561を下から平面視した場合、或いは、第2のクラッチ部材562を上から平面視した場合を想定)にほぼ等間隔に並ぶ6つの爪561a、562aが設けられているが、この爪の数は適宜変更してもよい。また、爪561a、562aの形状は、好ましい形状を適宜選択すればよい。 In the present embodiment, each of the two clutch members 561 and 562 has a circumferential direction (when the first clutch member 561 is seen in plan view from below, or the second clutch member 562 is seen in plan view from above. Assuming the case), six claws 561a and 562a arranged at almost equal intervals are provided, but the number of the claws may be appropriately changed. Moreover, what is necessary is just to select a preferable shape suitably for the shape of nail | claw 561a and 562a.
 第1のクラッチ部材561は、抜け止め対策を施された上で、第1の回転軸54に、その軸方向(図3A及び図3Bにおいて上下方向)に摺動可能、且つ、相対回転不能に取り付けられている。第1の回転軸54の第1のクラッチ部材561の上部側には、バネ71が遊嵌されている。このバネ71は、第1の回転軸54に設けられるストッパ部54aと第1のクラッチ部材561とに挟まれるように配置されており、第1のクラッチ部材561を下側に向けて付勢している。一方、第2のクラッチ部材562は、第2の回転軸57の上端に固定されている。 The first clutch member 561 is slidable in the axial direction (vertical direction in FIGS. 3A and 3B) with respect to the first rotating shaft 54 and is not relatively rotatable. It is attached. A spring 71 is loosely fitted on the upper side of the first clutch member 561 of the first rotating shaft 54. The spring 71 is disposed so as to be sandwiched between a stopper portion 54a provided on the first rotating shaft 54 and the first clutch member 561, and biases the first clutch member 561 downward. ing. On the other hand, the second clutch member 562 is fixed to the upper end of the second rotating shaft 57.
 クラッチ56における、動力伝達状態と動力遮断状態との切り替えは、下位置と上位置とに選択配置可能なアーム部72を用いて行われる。アーム部72は、その一部が第1のクラッチ部材561の下側に配置され、第1のクラッチ部材561の外周側と当接可能となっている。 Switching between the power transmission state and the power cut-off state in the clutch 56 is performed using the arm portion 72 that can be selectively arranged at the lower position and the upper position. A part of the arm portion 72 is disposed below the first clutch member 561 and can come into contact with the outer peripheral side of the first clutch member 561.
 アーム部72の駆動は、クラッチ用ソレノイド73を用いて行われる。クラッチ用ソレノイド73は、永久磁石73aを備え、いわゆる自己保持型のソレノイドとなっている。クラッチ用ソレノイド73のプランジャー73bは、アーム部72のプランジャー固定用の取付部72aに固定される。このために、電圧の印加によりハウジング73cからの突出量が変動するプランジャー73bの動きに合わせてアーム部72が動く。 The driving of the arm portion 72 is performed using a clutch solenoid 73. The clutch solenoid 73 includes a permanent magnet 73a and is a so-called self-holding solenoid. The plunger 73 b of the clutch solenoid 73 is fixed to the plunger fixing attachment portion 72 a of the arm portion 72. For this reason, the arm part 72 moves according to the movement of the plunger 73b in which the amount of protrusion from the housing 73c varies due to the application of voltage.
 アーム部72が下位置(図3Bの状態)から上位置(図3Aの状態)に移動すると、第1のクラッチ部材561は、アーム部72に押されてバネ71の付勢力に抗して上方向に移動する。アーム部72が上位置にある場合には、第1のクラッチ部材561と第2のクラッチ部材562とは噛み合わない。すなわち、アーム部72が上位置にある場合には、クラッチ56は動力遮断を行う。 When the arm portion 72 moves from the lower position (state shown in FIG. 3B) to the upper position (state shown in FIG. 3A), the first clutch member 561 is pushed by the arm portion 72 and moves upward against the urging force of the spring 71. Move in the direction. When the arm portion 72 is in the upper position, the first clutch member 561 and the second clutch member 562 do not mesh with each other. That is, when the arm portion 72 is in the upper position, the clutch 56 performs power interruption.
 一方、アーム部72が上位置から下位置に移動すると、第1のクラッチ部材561はバネ71の付勢力によって押される形で下方向に移動する。アーム部72が下位置にある場合には、第1のクラッチ部材561と第2のクラッチ部材562とは噛み合う。すなわち、アーム部72が下位置にある場合には、クラッチ56は動力伝達を行う。 On the other hand, when the arm part 72 moves from the upper position to the lower position, the first clutch member 561 moves downward while being pushed by the urging force of the spring 71. When the arm portion 72 is in the lower position, the first clutch member 561 and the second clutch member 562 are engaged with each other. That is, when the arm portion 72 is in the lower position, the clutch 56 transmits power.
 粉砕モータ60を駆動する際に、クラッチ56が動力伝達を行う状態(図3Bの状態)であると、原動軸11を高速回転させる回転動力が混練モータ50の出力軸51に伝達される(図2参照)。この場合、粉砕モータ60が例えば8000rpmで回転されるとすると、第1のプーリ52と第2のプーリ55との半径比(例えば1:5)によって、混練モータ50の出力軸51を40000rpmで回転させる力が必要になる。その結果、粉砕モータ60に非常に大きな負荷が加わるために、粉砕モータ60が破損する可能性がある。このため、粉砕モータ60を駆動する際には、原動軸11を高速回転させる回転動力が混練モータ50の出力軸51に伝達されないようにする必要がある。そこで、自動製パン器1は、上述のように、動力伝達と動力遮断を行うクラッチ56を第1の動力伝達部PT1に含む構成となっている。 When the crushing motor 60 is driven, if the clutch 56 is in a state where power is transmitted (the state shown in FIG. 3B), rotational power for rotating the driving shaft 11 at high speed is transmitted to the output shaft 51 of the kneading motor 50 (FIG. 2). In this case, if the crushing motor 60 is rotated at, for example, 8000 rpm, the output shaft 51 of the kneading motor 50 is rotated at 40000 rpm depending on the radius ratio (for example, 1: 5) between the first pulley 52 and the second pulley 55. The power to make it necessary. As a result, a very large load is applied to the pulverization motor 60, and the pulverization motor 60 may be damaged. For this reason, when driving the grinding motor 60, it is necessary to prevent the rotational power for rotating the driving shaft 11 from being transmitted to the output shaft 51 of the kneading motor 50. Thus, as described above, the automatic bread maker 1 includes the clutch 56 that performs power transmission and power interruption in the first power transmission unit PT1.
 なお、上述のように自動製パン器1においては、第2の動力伝達部PT2にはクラッチが設けられない構成としているが、これは次の理由による。すなわち、混練モータ50を駆動しても原動軸11は低速回転(例えば180rpm等)されるのみである。このため、原動軸11を回転させる回転動力が粉砕モータ60の出力軸に伝達されるようになっていても、混練モータ50に大きな負荷が加わることはない。そして、このように第2の動力伝達部PT2にクラッチが設けられない構成を敢えて採用することで、自動製パン器1の製造コストが抑制される。ただし、第2の動力伝達部PT2にクラッチが設けられる構成を採用しても、勿論構わない。 Note that, as described above, in the automatic bread maker 1, the second power transmission unit PT2 is not provided with a clutch, for the following reason. That is, even if the kneading motor 50 is driven, the driving shaft 11 is only rotated at a low speed (for example, 180 rpm). For this reason, even if the rotational power for rotating the driving shaft 11 is transmitted to the output shaft of the crushing motor 60, a large load is not applied to the kneading motor 50. And the manufacturing cost of the automatic bread maker 1 is suppressed by adopting the structure in which the clutch is not provided in the second power transmission part PT2 in this way. However, it goes without saying that a configuration in which a clutch is provided in the second power transmission unit PT2 may be adopted.
 図4は、本実施形態の自動製パン器における、パン容器が収容された焼成室及びその周辺の構成を模式的に示す図である。図4は、自動製パン器1を正面側から見た場合の構成を想定しており、焼成室30及びパン容器80の構成は概ね断面図で示されている。なお、パン原料が投入されるとともにパン焼き型として使用されるパン容器80は、焼成室30に対して出し入れ自在となっている。 FIG. 4 is a diagram schematically showing a configuration of a baking chamber in which a bread container is accommodated and its surroundings in the automatic bread maker of the present embodiment. FIG. 4 assumes a configuration when the automatic bread maker 1 is viewed from the front side, and the configurations of the baking chamber 30 and the bread container 80 are generally shown in cross-sectional views. In addition, the bread container 80 used as a baking mold while the bread raw material is input can be taken in and out of the baking chamber 30.
 図4に示すように、焼成室30の内部には、シーズヒータ31(加熱手段の一例)が焼成室30に収容されたパン容器80を包囲するように配置されている。このシーズヒータ31を用いることにより、パン容器80内のパン原料(生地となっている場合もある)の加熱が可能になる。 As shown in FIG. 4, a sheathed heater 31 (an example of a heating unit) is disposed inside the baking chamber 30 so as to surround a bread container 80 accommodated in the baking chamber 30. By using the sheathed heater 31, it is possible to heat the bread material (which may be a dough) in the bread container 80.
 また、焼成室30の底壁30aの略中心にあたる箇所には、パン容器80を支持するパン容器支持部14(例えばアルミニウム合金のダイキャスト成型品からなる)が固定されている。このパン容器支持部14は、焼成室30の底壁30aから窪むように形成され、その窪みの形状は上から見た場合に略円形となっている。このパン容器支持部14の中心には、上述の原動軸11が底壁30aに対して略垂直となるように支持されている。 Further, a bread container support portion 14 (for example, made of an aluminum alloy die-cast product) that supports the bread container 80 is fixed to a location that is substantially at the center of the bottom wall 30a of the baking chamber 30. The bread container support portion 14 is formed so as to be recessed from the bottom wall 30a of the baking chamber 30, and the shape of the recess is substantially circular when viewed from above. At the center of the bread container support portion 14, the above-described driving shaft 11 is supported so as to be substantially perpendicular to the bottom wall 30a.
 パン容器80は例えばアルミニウム合金のダイキャスト成型品(その他、板金等で構成しても構わない)であり、バケツのような形状をしており、開口部側縁に設けられる鍔部80aに手提げ用のハンドル(図示せず)が取り付けられている。パン容器80の水平断面は四隅を丸めた矩形である。また、パン容器80の底部には、詳細は後述するブレードユニット90の一部を収容する平面視略円形状の凹部81が形成されている。 The bread container 80 is, for example, an aluminum alloy die-cast molded product (others may be made of sheet metal or the like), has a bucket-like shape, and is handed to the flange 80a provided on the side edge of the opening. A handle (not shown) is attached. The horizontal cross section of the bread container 80 is a rectangle with rounded corners. Further, a concave portion 81 having a substantially circular shape in a plan view is formed on the bottom of the bread container 80 so as to accommodate a part of a blade unit 90 which will be described in detail later.
 パン容器80の底部中心には、垂直方向に延びるブレード回転軸82(本発明の回転軸の一例)が、シール対策を施された状態で回転可能に支持されている。このブレード回転軸82の下端(パン容器80の底部から外部側に突き出ている)には、容器側カップリング部材82aが固定されている。また、パン容器80の底部外面側には、ブレード回転軸82を取り囲むように筒状の台座83が設けられている。パン容器80は、この台座83がパン容器支持部14に受け入れられた状態で、焼成室30内に収容されるようになっている。なお、台座83は、パン容器80とは別に形成してもよいし、パン容器80と一体的に形成してもよい。 At the center of the bottom of the bread container 80, a blade rotation shaft 82 (an example of the rotation shaft of the present invention) extending in the vertical direction is rotatably supported in a state where a countermeasure against sealing is taken. A container side coupling member 82a is fixed to the lower end of the blade rotation shaft 82 (projecting outward from the bottom of the bread container 80). Further, a cylindrical base 83 is provided on the outer surface side of the bottom of the bread container 80 so as to surround the blade rotation shaft 82. The bread container 80 is accommodated in the baking chamber 30 in a state where the pedestal 83 is received by the bread container support portion 14. The pedestal 83 may be formed separately from the bread container 80 or may be formed integrally with the bread container 80.
 パン容器80の台座83がパン容器支持部14に受け入れられた状態で、パン容器80が焼成室30内に収容されると、ブレード回転軸82の下端に設けられる前述の容器側カップリング部材82aと、原動軸11の上端に固定される原動軸側カップリング部材11aとの連結(カップリング)が得られるようになる。そして、これにより、ブレード回転軸82は原動軸11から回転動力を伝えられるようになる。 When the bread container 80 is received in the baking chamber 30 in a state where the pedestal 83 of the bread container 80 is received by the bread container support portion 14, the container-side coupling member 82a provided at the lower end of the blade rotation shaft 82 is provided. Then, connection (coupling) with the driving shaft side coupling member 11a fixed to the upper end of the driving shaft 11 is obtained. As a result, the blade rotation shaft 82 can transmit the rotational power from the driving shaft 11.
 ブレード回転軸82のパン容器80内部に突出する部分には、その上からブレードユニット90が着脱可能に取り付けられるようになっている。このブレードユニット90の構成について、図5、図6、図7A、図7B、図8A、図8B、図9A、図9B、図10A、図10B、図10C及び図10Dを参照しながら説明する。 The blade unit 90 is detachably attached to a portion of the blade rotating shaft 82 protruding into the bread container 80 from above. The configuration of the blade unit 90 will be described with reference to FIGS. 5, 6, 7A, 7B, 8A, 8B, 9A, 9B, 10A, 10B, 10C, and 10D.

The broken lines in FIGS. 10B, 10C, and 10D are shown for ease of understanding and do not show a part of the grinding blade.
 ブレードユニット90は、大きくは、ユニット用シャフト91と、ユニット用シャフト91に相対回転不能に取り付けられる粉砕ブレード92と、ユニット用シャフト91に相対回転可能且つ粉砕ブレード92を上から覆うように取り付けられる平面視略円形のドーム状カバー93と、ドーム状カバー93に相対回転可能に取り付けられる混練ブレード101と、ドーム状カバー93に取り付けられ、粉砕ブレード92を下から覆うガード106と、を備える構成となっている(例えば、図5、図6、図7A及び図7B参照)。 The blade unit 90 is roughly attached to the unit shaft 91, the pulverizing blade 92 that is attached to the unit shaft 91 so as not to rotate relative to the unit shaft 91, and the relative rotation to the unit shaft 91 so as to cover the pulverizing blade 92 from above. A configuration comprising: a dome-shaped cover 93 that is substantially circular in plan view; a kneading blade 101 that is attached to the dome-shaped cover 93 so as to be relatively rotatable; and a guard 106 that is attached to the dome-shaped cover 93 and covers the grinding blade 92 from below. (See, for example, FIGS. 5, 6, 7A, and 7B).
 なお、ドーム状カバー93は本発明の第1のカバーの一例であり、ガード106は本発明の第2のカバーの一例である。また、ブレードユニット90がブレード回転軸82に取り付けられた状態において、粉砕ブレード92は、パン容器80の凹部81底面より少し上の箇所に位置する。また、粉砕ブレード92及びドーム状カバー93のほぼ全体は凹部81に収容される(例えば図4参照)。 The dome-shaped cover 93 is an example of the first cover of the present invention, and the guard 106 is an example of the second cover of the present invention. In the state where the blade unit 90 is attached to the blade rotation shaft 82, the crushing blade 92 is positioned slightly above the bottom surface of the recess 81 of the bread container 80. Further, almost the entire grinding blade 92 and the dome-shaped cover 93 are accommodated in the recess 81 (see, for example, FIG. 4).
 ユニット用シャフト91は、例えばステンレス鋼板等の金属によって形成される略円柱状の部材であり、一方端(下端)に開口が設けられ、その内部は中空となっている。すなわち、ユニット用シャフト91は、下端からブレード回転軸82を挿入できるように、挿入孔91cが形成された構成となっている(例えば図7B参照)。 The unit shaft 91 is a substantially cylindrical member formed of a metal such as a stainless steel plate, for example, and has an opening at one end (lower end), and the inside is hollow. That is, the unit shaft 91 has a configuration in which an insertion hole 91c is formed so that the blade rotation shaft 82 can be inserted from the lower end (see, for example, FIG. 7B).
 また、ユニット用シャフト91の側壁の下部側(開口側)には、ユニット用シャフト91の回転中心を挟んで対称配置される一対の切り欠き部91aが形成されている(例えば図6参照。ただし、図6では一対の切り欠き部91aの一方のみが示される)。切り欠き部91aの形状は側面視略矩形状であり、詳細には一方端(上端)が丸みを帯びている。切り欠き部91aは、ブレード回転軸82を水平に貫くピン821(図7B参照)に係合させるために設けられている。ブレード回転軸82のピン821と、切り欠き部91aとが係合することによって、ユニット用シャフト91はブレード回転軸82に相対回転不能に取り付けられた状態になる。 In addition, a pair of cutout portions 91a are formed on the lower side (opening side) of the side wall of the unit shaft 91 so as to be symmetrically arranged with respect to the rotation center of the unit shaft 91 (see, for example, FIG. 6). FIG. 6 shows only one of the pair of cutout portions 91a). The shape of the notch 91a is substantially rectangular in a side view, and in detail, one end (upper end) is rounded. The notch 91a is provided to engage the pin 821 (see FIG. 7B) that penetrates the blade rotation shaft 82 horizontally. When the pin 821 of the blade rotating shaft 82 and the notch 91a are engaged, the unit shaft 91 is attached to the blade rotating shaft 82 so as not to be relatively rotatable.
 図7Bに示すように、ブレード回転軸82(破線で示す)の上端面(略円形状)の中央部に設けられる凸部82bと係合するように、ユニット用シャフト91の内部側の上面中央部には凹部91bが形成されている。これにより、ユニット用シャフト91とブレード回転軸82との中心を合わせた状態で、ブレードユニット90はブレード回転軸82に容易に取り付けることができる。このために、ブレード回転軸82を回転させた場合に、不要なガタツキが発生することが抑制される。本実施形態では、ブレード回転軸82側に凸部82b、ユニット用シャフト91側に凹部91bを設ける構成としたが、これとは逆に、ブレード回転軸82側に凹部、ユニット用シャフト91側に凸部が設けられる構成としても構わない。 As shown in FIG. 7B, the center of the upper surface on the inner side of the unit shaft 91 so as to engage with a convex portion 82b provided at the center of the upper end surface (substantially circular) of the blade rotation shaft 82 (shown by a broken line). A concave portion 91b is formed in the portion. Accordingly, the blade unit 90 can be easily attached to the blade rotation shaft 82 in a state where the centers of the unit shaft 91 and the blade rotation shaft 82 are aligned. For this reason, when the blade rotating shaft 82 is rotated, occurrence of unnecessary rattling is suppressed. In the present embodiment, the convex portion 82b is provided on the blade rotating shaft 82 side and the concave portion 91b is provided on the unit shaft 91 side, but conversely, the concave portion is provided on the blade rotating shaft 82 side and the unit shaft 91 side is provided. A configuration in which a convex portion is provided may be employed.
 穀物粒粉砕用の粉砕ブレード92は、例えばステンレス鋼板を加工することによって形成される。この粉砕ブレード92は、例えば図6や図10A~図10Dに示すように、第1の切削部921と、第2の切削部922と、第1の切削部921と第2の切削部922とを連結する連結部923と、を備える。連結部923の中央部には、平面視略矩形状(スタジアム形状)の開口923aが形成されている。この開口923aにユニット用シャフト91の下部側が嵌め込まれる形で、粉砕ブレード92はユニット用シャフト91に取り付けられる。 The pulverization blade 92 for pulverizing grains is formed by processing a stainless steel plate, for example. For example, as shown in FIG. 6 and FIGS. 10A to 10D, the grinding blade 92 includes a first cutting portion 921, a second cutting portion 922, a first cutting portion 921 and a second cutting portion 922. And a connecting portion 923 for connecting the two. An opening 923 a having a substantially rectangular shape (stadium shape) in plan view is formed at the center of the connecting portion 923. The grinding blade 92 is attached to the unit shaft 91 such that the lower side of the unit shaft 91 is fitted into the opening 923a.
 なお、ユニット用シャフト91の下部側には、側面の一部(切り欠き部91aが設けられる位置近傍)を削って平坦面が形成されている。これにより、ユニット用シャフト91を下から平面視した場合に、ユニット用シャフト91の下部側は、連結部923に設けられる開口923aとほぼ同形状(略矩形状)となっている。ユニット用シャフト91の下部側を平面視した場合の面積は、開口923aより、ほんの僅かだけ小さくなっている。このような形状を採用しているために、粉砕ブレード92はユニット用シャフト91に相対回転不能に取り付けられる。粉砕ブレード92の下部側には抜け止め用のストッパ部材94がユニット用シャフト91に嵌め込まれるために、粉砕ブレード92がユニット用シャフト91から脱落することはない。 A flat surface is formed on the lower side of the unit shaft 91 by shaving a part of the side surface (near the position where the notch 91a is provided). Thereby, when the unit shaft 91 is viewed from below, the lower side of the unit shaft 91 has substantially the same shape (substantially rectangular shape) as the opening 923a provided in the connecting portion 923. The area when the lower side of the unit shaft 91 is viewed in plan is slightly smaller than the opening 923a. Since such a shape is adopted, the grinding blade 92 is attached to the unit shaft 91 so as not to be relatively rotatable. Since the stopper member 94 for preventing the retaining member 94 is fitted into the unit shaft 91 on the lower side of the pulverizing blade 92, the pulverizing blade 92 does not fall off the unit shaft 91.
 上から見た場合にいずれも略三角形状に形成される、第1の切削部921と第2の切削部922とは、連結部923を挟んで対向配置されている(図10A参照)。連結部923は、図10C及び図10Dに示すように、側面視略アーチ状となっており、開口923aが形成される天板部(平板状である)は、第1の切削部921及び第2の切削部922より高くなっている。 When viewed from above, the first cutting portion 921 and the second cutting portion 922, both of which are formed in a substantially triangular shape, are opposed to each other with the connecting portion 923 interposed therebetween (see FIG. 10A). As shown in FIGS. 10C and 10D, the connecting portion 923 has a substantially arched shape when viewed from the side, and the top plate portion (flat plate) in which the opening 923a is formed includes the first cutting portion 921 and the first cutting portion 921. 2 is higher than the cutting part 922.
 第1の切削部921の上面側の一辺には、端面に向けて徐々に厚みが薄くなるように研がれてなる第1の切削刃921aが形成されている。また、第2の切削部922の上面側の一辺には、端面に向けて徐々に厚みが薄くなるように研がれてなる第2の切削刃922aが形成されている。第1の切削刃921aと第2の切削部922aとは、図10Aに示すように連結部923を挟んで対向配置されている。この結果、図10Aにおいて粉砕ブレード92を反時計方向に回転すると、2つの切削刃921a、922aは、いずれも回転方向前方に位置することになり、切削機能を発揮するようになっている。 A first cutting blade 921a is formed on one side of the upper surface side of the first cutting portion 921 so as to be gradually thinned toward the end surface. In addition, a second cutting blade 922a is formed on one side of the upper surface side of the second cutting portion 922 so as to be gradually thinned toward the end surface. As shown in FIG. 10A, the first cutting blade 921a and the second cutting portion 922a are disposed to face each other with the connecting portion 923 interposed therebetween. As a result, when the pulverizing blade 92 is rotated counterclockwise in FIG. 10A, the two cutting blades 921a and 922a are both positioned forward in the rotational direction, thereby exhibiting a cutting function.
 第1の切削部921は、ブレードユニット90がブレード回転軸82に取り付けられた状態で、ブレード回転軸82に直交する面(以下、水平面と表現する場合がある)に略平行となるように設けられている(図10B~図10D参照)。換言すると、粉砕ブレード92が回転した場合に、第1の切削刃921aの回転軌道面が水平面に略平行となるように、第1の切削部921は設けられている。 The first cutting portion 921 is provided so as to be substantially parallel to a plane orthogonal to the blade rotation shaft 82 (hereinafter sometimes referred to as a horizontal plane) in a state where the blade unit 90 is attached to the blade rotation shaft 82. (See FIGS. 10B to 10D). In other words, when the grinding blade 92 rotates, the first cutting portion 921 is provided so that the rotation track surface of the first cutting blade 921a is substantially parallel to the horizontal plane.
 なお、図10Bと図10Cとは、互いに見る方向が異なる関係にあるが、いずれも、ブレードユニット90が鉛直方向に延びるブレード回転軸82に取り付けられた際の、粉砕ブレード92の側面図に該当する。 FIG. 10B and FIG. 10C have different relations of viewing directions, but both correspond to side views of the grinding blade 92 when the blade unit 90 is attached to the blade rotation shaft 82 extending in the vertical direction. To do.
 また、正確には、第1の切削部921は、ブレードユニット90がブレード回転軸82に取り付けられた状態で水平面に対して若干傾いている。しかし、この傾きは僅かであり、ここでは、この傾きは水平面に略平行な状態として扱っている。第1の切削部921は、場合によっては、ブレードユニット90がブレード回転軸82に取り付けられた状態で水平面に対して完全に平行となっていてもよい。 In addition, to be precise, the first cutting portion 921 is slightly inclined with respect to the horizontal plane in a state where the blade unit 90 is attached to the blade rotation shaft 82. However, this inclination is slight, and here, this inclination is treated as being substantially parallel to the horizontal plane. In some cases, the first cutting portion 921 may be completely parallel to the horizontal plane with the blade unit 90 attached to the blade rotation shaft 82.
 第2の切削部922は、水平状態から捻られて得られるような形状であり、傾斜構造となっている。このため、ブレードユニット90がブレード回転軸82に取り付けられた状態で、水平面に対して傾いている(図10B~図10D参照)。より詳細には、第2の切削部922は、第2の切削刃922aが外周側(図10Cの左側が該当)から内周側(図10Cの右側が該当)に向けて徐々に低くなるように傾斜している。また、第2の切削部922は、第2の切削刃922aが無い側(図10Bの左側が該当)から第2の切削刃922aが有る側(図10Bの右側が該当)に向かって徐々に低くなるように傾斜している。 The second cutting part 922 has a shape obtained by being twisted from a horizontal state, and has an inclined structure. Therefore, the blade unit 90 is inclined with respect to the horizontal plane in a state where the blade unit 90 is attached to the blade rotation shaft 82 (see FIGS. 10B to 10D). More specifically, in the second cutting portion 922, the second cutting blade 922a is gradually lowered from the outer peripheral side (the left side in FIG. 10C corresponds) to the inner peripheral side (the right side in FIG. 10C corresponds). It is inclined to. Further, the second cutting portion 922 gradually moves from the side without the second cutting blade 922a (the left side in FIG. 10B corresponds) toward the side with the second cutting blade 922a (the right side in FIG. 10B corresponds). Inclined to be lower.
 また、第1の切削刃921aと第2の切削刃922aとは、ブレードユニット90がブレード回転軸82に取り付けられた状態において、パン容器80の底面(詳細には凹部81の底面)からの高さが異なる位置を回転するように設けられている。詳細には、第1の切削刃921aの方が第2の切削刃922aに比べて低い位置を回転するようになっている。 In addition, the first cutting blade 921a and the second cutting blade 922a are arranged so that the height from the bottom surface of the bread container 80 (specifically, the bottom surface of the recess 81) in a state where the blade unit 90 is attached to the blade rotation shaft 82. Are provided to rotate at different positions. Specifically, the first cutting blade 921a rotates at a lower position than the second cutting blade 922a.
 なお、正確には、第1の切削刃921aの最内周側位置と、第2の切削刃922aの最内周側位置とは、ブレードユニット90がブレード回転軸82に取り付けられた状態において、パン容器80の底面からの高さはほぼ同一となっている。すなわち、本実施形態では、正確には、第1の切削刃921aの一部が第2の切削刃922aに比べて低い位置を回転する構成である。ただし、第1の切削刃921aの全てが第2の切削刃922aの全てに比べて低い位置を回転するようにしてもよい。 To be precise, the innermost circumferential side position of the first cutting blade 921a and the innermost circumferential side position of the second cutting blade 922a are in a state where the blade unit 90 is attached to the blade rotating shaft 82. The height from the bottom surface of the bread container 80 is substantially the same. That is, in this embodiment, more precisely, a part of the first cutting blade 921a rotates at a lower position than the second cutting blade 922a. However, all of the first cutting blades 921a may rotate at a lower position than all of the second cutting blades 922a.
 粉砕ブレード92を囲んで覆い隠すように配置されるドーム状カバー93は、例えばアルミニウム合金のダイキャスト成型品からなり、その内面側には、ベアリング95(本実施形態では転がり軸受けを使用している)を収容する凹状の収容部931(図7B参照)が形成されている。換言すると、この収容部931を形成するために、ドーム状カバー93は、それを外面から見た場合に、中央部に略円柱状の凸部93aが形成された構成となっている。なお、凸部93aには開口が形成されておらず、収容部931に収容されるベアリング95はその側面及び上面が収容部931の壁面に囲い込まれた状態となっている。 The dome-shaped cover 93 disposed so as to surround and cover the crushing blade 92 is made of, for example, an aluminum alloy die-cast product, and a bearing 95 (in this embodiment, a rolling bearing is used on the inner surface side thereof. ) (See FIG. 7B) is formed. In other words, in order to form the accommodating portion 931, the dome-shaped cover 93 has a configuration in which a substantially cylindrical convex portion 93a is formed at the center when viewed from the outer surface. In addition, the opening is not formed in the convex part 93a, and the bearing 95 accommodated in the accommodating part 931 is in the state in which the side surface and the upper surface are enclosed by the wall surface of the accommodating part 931.
 ベアリング95は上下に抜け止めリング96a、96bが配置された状態で、その内輪95aがユニット用シャフト91に相対回転不能に取り付けられている(内輪95a内側の貫通孔にユニット用シャフト91が圧入されている)。また、ベアリング95は、その外輪95bの外壁が収容部931の側壁に固定されるように、収容部931に圧入されている。このベアリング95(内輪95aが外輪95bに対して相対回転する)の介在によって、ドーム状カバー93はユニット用シャフト91に相対回転可能に取り付けられている。 The inner ring 95a is attached to the unit shaft 91 so as not to rotate relative to the bearing 95 with the retaining rings 96a and 96b arranged on the upper and lower sides (the unit shaft 91 is press-fitted into a through hole inside the inner ring 95a. ing). The bearing 95 is press-fitted into the housing portion 931 so that the outer wall of the outer ring 95b is fixed to the side wall of the housing portion 931. The dome-shaped cover 93 is attached to the unit shaft 91 so as to be rotatable relative to the bearing 95 (the inner ring 95a rotates relative to the outer ring 95b).
 また、ドーム状カバー93の収容部931には、外部からベアリング95内に異物(例えば穀物粒の粉砕時に用いられる液体や粉砕により得られたペースト状物等)が入り込まないように、例えばシリコン系或いはフッ素系の材料によって形成されるシール材97及び、このシール材97を保持する金属製のシールカバー98が、ベアリング95の下部側から圧入されている。シールカバー98は、ドーム状カバー93への固定が確実となるように、リベット99によってドーム状カバー93に固着されている。このリベット99による固定は行わなくてもよいが、確実な固定を得るために、本実施形態のように構成するのが好ましい。なお、シール材97及びシールカバー98はシール手段として機能する。 In addition, the housing portion 931 of the dome-shaped cover 93 is made of, for example, a silicon-based material so that foreign matter (for example, liquid used when pulverizing grain grains or paste-like material obtained by pulverization) does not enter the bearing 95 from the outside. Alternatively, a seal material 97 formed of a fluorine-based material and a metal seal cover 98 that holds the seal material 97 are press-fitted from the lower side of the bearing 95. The seal cover 98 is fixed to the dome-shaped cover 93 with a rivet 99 so that the fixing to the dome-shaped cover 93 is ensured. Although fixing with the rivet 99 may not be performed, it is preferable to configure as in the present embodiment in order to obtain reliable fixing. The sealing material 97 and the sealing cover 98 function as sealing means.
 ドーム状カバー93の外面には、凸部93aに隣接する箇所に垂直方向に延びるように配置される支軸100(図6参照)により、平面形状「く」の字形の混練ブレード101(例えばアルミニウム合金のダイキャスト成型品からなる)が取り付けられている。混練ブレード101は、支軸100に相対回転不能に取り付けられており、ドーム状カバー93に相対回転可能に取り付けられる支軸100と動きを共にする。換言すると、混練ブレード101は、ドーム状カバー93に対して相対回転可能に取り付けられた構成となっている。 On the outer surface of the dome-shaped cover 93, a kneading blade 101 (for example, aluminum) in a planar shape is formed by a support shaft 100 (see FIG. 6) disposed so as to extend in a vertical direction at a location adjacent to the convex portion 93 a. (Made of die-cast alloy product) is attached. The kneading blade 101 is attached to the support shaft 100 so as not to be relatively rotatable, and moves together with the support shaft 100 attached to the dome-shaped cover 93 so as to be relatively rotatable. In other words, the kneading blade 101 is attached to the dome-shaped cover 93 so as to be relatively rotatable.
 混練ブレード101の先端(支軸100を中心として混練ブレード101を回転したときに最も大きな円を描く部分を想定)側近傍の一方面には、図5、図6、図7A、図7B、図8A、図8B、図9A及び図9Bに示すように緩衝材107が取り付けられている。緩衝材107は、混練ブレード101の先端から僅かに突出するように設けられている(例えば図8B参照)。なお、本実施形態では3mm程度突出する(d≒3mm)ように設けられている。 On one surface near the tip of the kneading blade 101 (assuming a portion that draws the largest circle when the kneading blade 101 is rotated about the support shaft 100), FIG. 5, FIG. 6, FIG. 7A, FIG. As shown in FIGS. 8A, 8B, 9A, and 9B, a cushioning material 107 is attached. The buffer material 107 is provided so as to slightly protrude from the tip of the kneading blade 101 (see, for example, FIG. 8B). In the present embodiment, it is provided so as to protrude about 3 mm (d≈3 mm).
 緩衝材107の固定は、混練ブレード101の一方面と固定用板108とで緩衝材107を挟持した状態とし、混練ブレード101の他方面側から挿入されるリベット109のカシメで得られる構成となっている。なお、本実施形態ではリベット109の数を2つとしているが、その数が限定されないのは言うまでもない。 The buffer material 107 is fixed in a state where the buffer material 107 is sandwiched between one surface of the kneading blade 101 and the fixing plate 108 and obtained by caulking the rivet 109 inserted from the other surface side of the kneading blade 101. ing. In the present embodiment, the number of rivets 109 is two, but it goes without saying that the number is not limited.
 この緩衝材107は、混練ブレード101が詳細は後述する開き姿勢となった場合に、パン容器80(の内壁)と直接接触しないように配置されている。混練ブレード101とパン容器80とが直接接触すると、それらの間の干渉が原因となって破損が発生する可能性があり、このような破損を防止すべく緩衝材107は設けられている。 The buffer material 107 is disposed so as not to directly contact the bread container 80 (inner wall) when the kneading blade 101 is in an open posture, which will be described in detail later. When the kneading blade 101 and the bread container 80 are in direct contact with each other, damage may occur due to interference between them, and the buffer material 107 is provided to prevent such damage.
 本実施形態の自動製パン器1においては、パン容器80及び混練ブレード101の表面にはフッ素コーティングが施されている。このため、本実施形態の緩衝材107は、このフッ素コーティングが混練ブレード101とパン容器80との接触で剥がれないように設けられたものといえる。そして、この点から、緩衝材107を構成する材料としては、フッ素コーティングを剥がさないようにコーティング材よりも柔らかい材料が好ましく、例えば、シリコーンゴムやTPE(Thermoplastic Elastomers;熱可塑性エラストマ)等が用いられる。また、緩衝材107は防音対策としても機能するが、この点は後述する。なお、以下では、この緩衝材107も混練ブレード101の一部と見なして説明が行われる場合がある。 In the automatic bread maker 1 of the present embodiment, the surface of the bread container 80 and the kneading blade 101 is coated with fluorine. For this reason, it can be said that the buffer material 107 of the present embodiment is provided so that the fluorine coating is not peeled off by contact between the kneading blade 101 and the pan container 80. From this point, the material constituting the cushioning material 107 is preferably a material softer than the coating material so as not to peel off the fluorine coating, and for example, silicone rubber, TPE (Thermoplastic Elastomers) or the like is used. . The buffer material 107 also functions as a soundproofing measure, which will be described later. In the following description, the buffer material 107 may be regarded as a part of the kneading blade 101.
 また、本実施形態では、ドーム状カバー93の外面に、混練ブレード101に並ぶように補完混練ブレード102(例えばアルミニウム合金のダイキャスト成型品からなる)が固定配置されている。この補完混練ブレード102は、必ずしも設ける必要がないが、パン生地を練り上げる練り工程における混練効率を高めるために設けるのが好ましい。 Further, in this embodiment, the complementary kneading blade 102 (for example, made of an aluminum alloy die cast product) is fixedly arranged on the outer surface of the dome-shaped cover 93 so as to be aligned with the kneading blade 101. The complementary kneading blade 102 is not necessarily provided, but is preferably provided in order to increase the kneading efficiency in the kneading process of kneading the bread dough.
 ここで、混練ブレード101の動作について説明する。混練ブレード101は、支軸100と共に支軸100の軸線周りに回転し、図5、図7A、図8A及び図9Aに示す折り畳み姿勢と、図8B及び図9Bに示す開き姿勢との2姿勢をとる。折り畳み姿勢では、混練ブレード101の下縁から垂下した突起101a(図6参照)がドーム状カバー93の上面(外面)に設けられた第1のストッパ部93bに当接する。このために、混練ブレード101は、それ以上ドーム状カバー93に対して反時計方向(上から見た場合を想定)の回動を行うことができない。この折り畳み姿勢では、混練ブレード101の先端がドーム状カバー93から少し突き出している。 Here, the operation of the kneading blade 101 will be described. The kneading blade 101 rotates about the axis of the support shaft 100 together with the support shaft 100, and has two postures, a folded posture shown in FIGS. 5, 7A, 8A and 9A, and an open posture shown in FIGS. 8B and 9B. Take. In the folded position, the protrusion 101a (see FIG. 6) hanging from the lower edge of the kneading blade 101 comes into contact with the first stopper portion 93b provided on the upper surface (outer surface) of the dome-shaped cover 93. For this reason, the kneading blade 101 cannot further rotate counterclockwise (assuming the case viewed from above) with respect to the dome-shaped cover 93. In this folded position, the tip of the kneading blade 101 protrudes slightly from the dome-shaped cover 93.
 この姿勢(図9Aの状態)から混練ブレード101がドーム状カバー93に対して時計方向(上から見た場合を想定)に回動して図9Bに示す開き姿勢になると、混練ブレード101の先端はドーム状カバー93から大きく突き出す。この開き姿勢における混練ブレード101の開き角度は、ドーム状カバー93の内面に設けられる第2のストッパ部93c(図8B参照)によって制限される。詳細は後述する第2係合体103b(支軸100に固定される)が、ドーム状カバー93の内面に設けられる第2のストッパ部93cに当って回転できなくなった時点で、混練ブレード101は最大開き角度となる。 When the kneading blade 101 is rotated clockwise (assumed when viewed from above) with respect to the dome-shaped cover 93 from this posture (the state shown in FIG. 9A), the tip of the kneading blade 101 is moved to the open posture shown in FIG. Protrudes greatly from the dome-shaped cover 93. The opening angle of the kneading blade 101 in this opening posture is limited by the second stopper portion 93 c (see FIG. 8B) provided on the inner surface of the dome-shaped cover 93. When the second engagement body 103b (fixed to the support shaft 100), which will be described in detail later, is unable to rotate by hitting the second stopper portion 93c provided on the inner surface of the dome-shaped cover 93, the kneading blade 101 is at its maximum. The opening angle.
 なお、混練ブレード101が折り畳み姿勢となっている場合には、例えば図5や図7Aに示すように補完混練ブレード102は混練ブレード101に整列し、あたかも「く」の字形状の混練ブレード101のサイズが大型化したようになる。 When the kneading blade 101 is in the folded position, the complementary kneading blade 102 is aligned with the kneading blade 101 as shown in FIGS. 5 and 7A, for example. The size becomes larger.
 ところで、ユニット用シャフト91には、例えば図6に示すように、粉砕ブレード92とシールカバー98との間にカバー用クラッチ103(本発明のクラッチの一例)を構成する第1係合体103aが取り付けられている。例えば亜鉛ダイカストからなる第1係合体103aには略矩形状(スタジアム形状)の開口103aaが形成されており、この開口103aaにユニット用シャフト91の下部側の平面視略矩形状部分が嵌め込まれることにより、第1係合体103aはユニット用シャフト91に相対回転不能に取り付けられている。この第1係合体103aは粉砕ブレード92よりも先に、ユニット用シャフト91の下側から取り付けられ、ストッパ部材94によって、粉砕ブレード92と共にユニット用シャフト91からの脱落が防止されている。なお、本実施形態では、第1係合体103aとシールカバー98との間には、第1係合体103aの劣化防止等を考慮してワッシャ104を配置する構成としているが、このワッシャ104は必ずしも設けなくてもよい。 Incidentally, for example, as shown in FIG. 6, a first engagement body 103 a constituting a cover clutch 103 (an example of the clutch of the present invention) is attached to the unit shaft 91 between the pulverization blade 92 and the seal cover 98. It has been. For example, a substantially rectangular (stadium-shaped) opening 103aa is formed in the first engaging body 103a made of zinc die casting, and a substantially rectangular portion in plan view on the lower side of the unit shaft 91 is fitted into the opening 103aa. Thus, the first engagement body 103a is attached to the unit shaft 91 so as not to be relatively rotatable. The first engaging body 103a is attached from the lower side of the unit shaft 91 prior to the crushing blade 92, and the stopper member 94 prevents the unit shaft 91 from dropping off together with the crushing blade 92. In the present embodiment, the washer 104 is disposed between the first engagement body 103a and the seal cover 98 in consideration of prevention of deterioration of the first engagement body 103a. However, the washer 104 is not necessarily provided. It does not have to be provided.
 また、混練ブレード101が取り付けられる支軸100の下部側には、カバー用クラッチ103を構成する第2係合体103bが取り付けられている。例えば亜鉛ダイカストからなる第2係合体103bには略矩形状(スタジアム形状)の開口103baが形成されており、この開口103baに支軸100の下部側の平面視略矩形状部分が嵌め込まれることにより、第2係合体103bは支軸100に相対回転不能に取り付けられている。なお、本実施形態では、第2係合体103bの上側に、第2係合体103bの劣化防止等を考慮してワッシャ105を配置する構成としているが、このワッシャ105は必ずしも設けなくてもよい。 Further, a second engagement body 103b constituting the cover clutch 103 is attached to the lower side of the support shaft 100 to which the kneading blade 101 is attached. For example, a substantially rectangular (stadium-shaped) opening 103ba is formed in the second engaging body 103b made of zinc die casting, and a substantially rectangular portion in plan view on the lower side of the support shaft 100 is fitted into the opening 103ba. The second engagement body 103b is attached to the support shaft 100 so as not to be relatively rotatable. In the present embodiment, the washer 105 is arranged on the upper side of the second engagement body 103b in consideration of prevention of deterioration of the second engagement body 103b. However, the washer 105 is not necessarily provided.
 第1係合体103aと第2係合体103bとで構成されるカバー用クラッチ103は、ブレード回転軸82の回転動力をドーム状カバー93に伝達するか否かを切り替えるクラッチとして機能する。カバー用クラッチ103は、混練モータ50が原動軸11を回転させるときのブレード回転軸82の回転方向(この回転方向を「正方向回転」とする。図8A及び図8Bでは反時計方向回転、図9A及び図9Bでは時計方向回転となる。本発明の「一方向」に該当する。)において、ブレード回転軸82の回転動力をドーム状カバー93に伝達する。逆に、粉砕モータ60が原動軸11を回転させるときのブレード回転軸82の回転方向(この回転方向を「逆方向回転」とする。図8A及び図8Bでは時計方向回転、図9A及び図9Bでは反時計方向回転となる。本発明の「一方向と逆方向」に該当する。)においては、カバー用クラッチ103は、ブレード回転軸82の回転動力をドーム状カバー93に伝達しない。以下、このカバー用クラッチ103の動作について更に詳細に説明する。 The cover clutch 103 composed of the first engagement body 103a and the second engagement body 103b functions as a clutch for switching whether or not to transmit the rotational power of the blade rotation shaft 82 to the dome-shaped cover 93. The cover clutch 103 is a rotation direction of the blade rotation shaft 82 when the kneading motor 50 rotates the driving shaft 11 (this rotation direction is referred to as “forward rotation”. In FIGS. 8A and 8B, the rotation is counterclockwise. 9A and 9B, the rotation is clockwise (corresponding to “one direction” in the present invention), and the rotational power of the blade rotation shaft 82 is transmitted to the dome-shaped cover 93. Conversely, the rotation direction of the blade rotation shaft 82 when the crushing motor 60 rotates the drive shaft 11 (this rotation direction is referred to as “reverse rotation”. FIGS. 8A and 8B rotate clockwise, and FIGS. 9A and 9B show rotation directions). In this case, the cover clutch 103 does not transmit the rotational power of the blade rotating shaft 82 to the dome-shaped cover 93. Hereinafter, the operation of the cover clutch 103 will be described in more detail.
 混練ブレード101が折り畳み姿勢にある場合(例えば図8A、図9Aの状態)、第2係合体103bの係合部103bbは第1係合体103aの係合部103ab(本実施形態では2つあるが1つでもよい)の回転軌道に干渉する角度となる(図8Aの破線参照)。このため、ブレード回転軸82が正方向回転すると、第1係合体103aと第2係合体103bは係合し、ブレード回転軸82の回転動力がドーム状カバー93に伝達される。 When the kneading blade 101 is in the folded position (for example, the state shown in FIGS. 8A and 9A), the engagement portion 103bb of the second engagement body 103b is the engagement portion 103ab of the first engagement body 103a (although there are two in this embodiment). It is an angle that interferes with the rotation trajectory (see FIG. 8A). Therefore, when the blade rotation shaft 82 rotates in the forward direction, the first engagement body 103 a and the second engagement body 103 b are engaged, and the rotational power of the blade rotation shaft 82 is transmitted to the dome-shaped cover 93.
 一方、混練ブレード101が開き姿勢にある場合(例えば図8B、図9Bの状態)、第2係合体103bの係合部103bbは第1係合体103aの係合部103abの回転軌道から逸脱した角度となる(図8Bの破線参照)。このために、ブレード回転軸82が回転しても、第1係合体103aと第2係合体103bは係合しない。従って、ブレード回転軸82の回転動力はドーム状カバー93に伝達されない。 On the other hand, when the kneading blade 101 is in the open posture (for example, the state shown in FIGS. 8B and 9B), the engagement portion 103bb of the second engagement body 103b deviates from the rotation trajectory of the engagement portion 103ab of the first engagement body 103a. (See the broken line in FIG. 8B). For this reason, even if the blade rotation shaft 82 rotates, the first engagement body 103a and the second engagement body 103b are not engaged. Accordingly, the rotational power of the blade rotation shaft 82 is not transmitted to the dome-shaped cover 93.
 例えば図5及び図6に示すように、ドーム状カバー93には、カバー内空間とカバー外空間を連通する窓93dが形成される。窓93dは粉砕ブレード92に並ぶ高さか、それよりも上の位置に配置される。なお、本実施形態では、計4個の窓93dが90°間隔で並んでいるが、それ以外の数と配置間隔を選択することもできる。 For example, as shown in FIGS. 5 and 6, the dome-shaped cover 93 is formed with a window 93d that communicates the space inside the cover and the space outside the cover. The window 93d is arranged at a height equal to or higher than the grinding blade 92. In the present embodiment, a total of four windows 93d are arranged at intervals of 90 °, but other numbers and arrangement intervals can be selected.
 また、ドーム状カバー93内面には、各窓93dに対応して計4個のリブ93eが形成されている(図8A及び図8B参照)。各リブ93eはドーム状カバー93の中心近傍から外周の環状壁まで半径方向に対して斜めに延び、4個合わさって一種の巴形状を構成する。また、各リブ93eは、それに向かって押し寄せるパン原料に対面する側が凸となるように湾曲している。 Further, a total of four ribs 93e are formed on the inner surface of the dome-shaped cover 93 corresponding to each window 93d (see FIGS. 8A and 8B). Each rib 93e extends obliquely from the vicinity of the center of the dome-shaped cover 93 to the outer peripheral annular wall with respect to the radial direction, and the four ribs 93e form a kind of bowl shape. Moreover, each rib 93e is curving so that the side which faces the bread raw material pressed toward it may become convex.
 また、ドーム状カバー93の下面には、ガード106が着脱可能に取り付けられている。このガード106は、ドーム状カバー93の下面を覆って粉砕ブレード92にユーザの指が接近するのを阻止する。ガード106は、例えば耐熱性を有するエンジニアリングプラスチックによって形成され、例えばPPS(ポリフェニレンサルファイド)等の成型品とできる。なお、このガード106は設けなくても構わないが、ユーザの安全を確保する目的等から、設けるのが好ましい。 Also, a guard 106 is detachably attached to the lower surface of the dome-shaped cover 93. The guard 106 covers the lower surface of the dome-shaped cover 93 and prevents the user's finger from approaching the grinding blade 92. The guard 106 is formed of, for example, an engineering plastic having heat resistance, and can be a molded product such as PPS (polyphenylene sulfide). The guard 106 need not be provided, but is preferably provided for the purpose of ensuring the safety of the user.
 例えば図6に示すように、ガード106の中心には、ユニット用シャフト91に固定されるストッパ部材94を通すリング状のハブ106a(本発明の内側環状部の一例)がある。また、ガード106の周縁には、ハブ106aの外側に同心円状に設けられたリング状のリム106b(本発明の外側環状部の一例)がある。ハブ106aとリム106bとは複数のスポーク106c(本発明の連結部の一例)で連結される。複数のスポーク106cは所定の間隔を置いて配置され、スポーク106c同士の間は、粉砕ブレード92によって粉砕される穀物粒を通す開口部106dとなる。開口部106dは、指が通り抜けられない程度の大きさとなっている。 For example, as shown in FIG. 6, at the center of the guard 106, there is a ring-shaped hub 106a (an example of the inner annular portion of the present invention) through which a stopper member 94 fixed to the unit shaft 91 is passed. Further, at the periphery of the guard 106, there is a ring-shaped rim 106b (an example of the outer annular portion of the present invention) provided concentrically outside the hub 106a. The hub 106a and the rim 106b are connected by a plurality of spokes 106c (an example of the connecting portion of the present invention). The plurality of spokes 106c are arranged at a predetermined interval, and between the spokes 106c are openings 106d through which grain grains pulverized by the pulverizing blade 92 pass. The opening 106d has a size that prevents a finger from passing through.
 ガード106のスポーク106cは、ドーム状カバー93に取り付けられた時、粉砕ブレード92と近接状態となる。そして、あたかも、ガード106が回転式電気かみそりの外刃で、粉砕ブレード92が内刃のような形になる。 When the spoke 106 c of the guard 106 is attached to the dome-shaped cover 93, the spoke 106 c comes into close proximity with the grinding blade 92. The guard 106 is shaped like an outer blade of a rotary electric razor, and the grinding blade 92 is shaped like an inner blade.
 リム106bの周縁には、90°間隔で計4個(この構成に限定されないのは言うまでもない)の柱106eが一体成形されている。この柱106eのガード106中心側を向いた側面には、一端が行き止まりになった水平な溝106eaが形成される。この溝106eaと、ドーム状カバー93の外周に形成される突起93f(これも90°間隔で計4個配置されている)とを係合させることによって、ガード106はドーム状カバー93に取り付けられる。なお、詳細な説明は省略するが、溝106eaと突起93fとは、バヨネット結合を構成するように設けられている。複数の柱106eの各々は、ブレード回転軸82が正方向回転する場合に回転方向前面となる側面106ebが斜め上向きとなるように傾斜している。 A total of four columns 106e (not limited to this configuration) are integrally formed at the periphery of the rim 106b at intervals of 90 °. A horizontal groove 106ea having one end dead end is formed on a side surface of the pillar 106e facing the center side of the guard 106. The guard 106 is attached to the dome-shaped cover 93 by engaging the grooves 106 ea with the projections 93 f formed on the outer periphery of the dome-shaped cover 93 (all four are arranged at intervals of 90 °). . Although detailed description is omitted, the groove 106ea and the protrusion 93f are provided so as to constitute a bayonet coupling. Each of the plurality of pillars 106e is inclined such that the side surface 106eb that is the front surface in the rotation direction is obliquely upward when the blade rotation shaft 82 rotates in the forward direction.
 以上のように、本実施形態の自動製パン器1では、粉砕ブレード92及び混練ブレード101を1つのユニット(ブレードユニット90)に組み込む構成としているので、その取り扱いが便利である。ユーザは、ブレードユニット90をブレード回転軸82から簡単に引き抜くことが可能であり、製パン作業終了後にブレードの洗浄を手軽に行うことができる。また、ブレードユニット90が備える粉砕ブレード92は、ユニット用シャフト91に着脱可能に取り付けられるものであり、その量産が行いやすく、ブレード交換等のメンテナンス性にも優れる。 As described above, in the automatic bread maker 1 of the present embodiment, since the crushing blade 92 and the kneading blade 101 are incorporated into one unit (blade unit 90), the handling thereof is convenient. The user can easily pull out the blade unit 90 from the blade rotating shaft 82, and can easily clean the blade after the bread making operation. Further, the pulverizing blade 92 provided in the blade unit 90 is detachably attached to the unit shaft 91, and is easily mass-produced and has excellent maintainability such as blade replacement.
 また、本実施形態の自動製パン器1では、パン容器80に水等の液体が入れられるために、ベアリング95に液体が入り込まないように、ベアリング95は密閉構造とされるのが好ましい。この点、自動製パン器1では、ベアリング95がドーム状カバー93に設けられる凹状の収容部931に収容されているために、ドーム状カバーの内面側にのみシール手段(シール材97及びシールカバー98)を設ければ、ベアリング95を密閉する構造が得られる。このため、ベアリング95の上下にシール手段を設ける必要がなく、ベアリング95のシール構造の小型化が図れる。このため、自動製パン器1では、焼き上がったパンの形状に対する悪影響(例えば、パンの底面が大きく凹む等)を抑制することが可能になる。 Further, in the automatic bread maker 1 of the present embodiment, since a liquid such as water is put in the bread container 80, the bearing 95 is preferably a sealed structure so that the liquid does not enter the bearing 95. In this respect, in the automatic bread maker 1, since the bearing 95 is accommodated in the concave accommodating portion 931 provided in the dome-shaped cover 93, the sealing means (the sealing material 97 and the seal cover only on the inner surface side of the dome-shaped cover 93). 98), a structure for sealing the bearing 95 is obtained. For this reason, it is not necessary to provide sealing means above and below the bearing 95, and the seal structure of the bearing 95 can be downsized. For this reason, in the automatic bread maker 1, it is possible to suppress an adverse effect on the shape of the baked bread (for example, the bottom surface of the bread is greatly recessed).
 図11は、本実施形態の自動製パン器の構成を示すブロック図である。図11に示すように、自動製パン器1における制御動作は制御装置120によって行われる。制御装置120は、例えば、CPU(Central Processing Unit)、ROM(Read Only Memory)、RAM(Random Access Memory)、I/O(input/output)回路部等からなるマイクロコンピュータ(マイコン)によって構成される。この制御装置120は、焼成室30の熱の影響を受け難い位置に配置するのが好ましい。また、制御装置120には、時間計測機能が備えられており、パンの製造工程における時間的な制御が可能となっている。 FIG. 11 is a block diagram showing a configuration of the automatic bread maker according to the present embodiment.

(自動製パン器の動作)
 次に、以上のように構成される自動製パン器1でパンを製造する場合の動作について説明する。ここでは、自動製パン器1によって米粒を出発原料に用いてパンを製造する場合を例に、自動製パン器1の動作を説明する。
(Operation of automatic bread machine)
Next, the operation in the case of producing bread with the automatic bread maker 1 configured as described above will be described. Here, the operation of the automatic bread maker 1 will be described by taking as an example a case where bread is produced by using the rice grain as a starting material by the automatic bread maker 1.
 米粒が出発原料に用いられる場合には、米粒用製パンコースが実行される。図12は自動製パン器によって実行される米粒用製パンコースの流れを示す模式図である。図12に示すように、米粒用製パンコースにおいては、浸漬工程と、粉砕工程と、休止工程と、練り(捏ね)工程と、発酵工程と、焼成工程と、がこの順番で順次に実行される。 When the rice grain is used as a starting material, a bread-making course for rice grain is executed. FIG. 12 is a schematic diagram showing the flow of the bread making course for rice grains executed by the automatic bread maker. As shown in FIG. 12, in the bread making course for rice grains, the dipping process, the pulverizing process, the pause process, the kneading (kneading) process, the fermentation process, and the baking process are sequentially performed in this order. The
 米粒用製パンコースを開始するにあたって、ユーザは、パン容器80のブレード回転軸82にユニット用シャフト91を被せることによって、ブレードユニット90をブレード回転軸82に取り付ける。上述のように、ブレードユニット90がガード106を備える構成であるために、この作業時にユーザの指が粉砕ブレード92に触れることがなく、ユーザは安全に作業を行える。このブレードユニット90の取り付け作業後に、ユーザは、米粒、水、調味料(例えば食塩、砂糖、ショートニング等)をそれぞれ所定量ずつ計量してパン容器80に入れる。 In starting the bread making course for rice grains, the user attaches the blade unit 90 to the blade rotation shaft 82 by covering the blade rotation shaft 82 of the bread container 80 with the unit shaft 91. As described above, since the blade unit 90 includes the guard 106, the user's finger does not touch the crushing blade 92 during this work, and the user can work safely. After the operation of attaching the blade unit 90, the user weighs rice grains, water, and seasonings (for example, salt, sugar, shortening, etc.) in predetermined amounts and puts them in the bread container 80.
 また、ユーザは、パンの製造工程の途中で自動投入されるパン原料を計量してパン原料収納容器42の容器本体42aに入れる。そして、ユーザは、収納すべきパン原料を容器本体42aに収納したら、可動フック42cによって容器蓋42bを支えることにより、容器本体42aの開口が容器蓋42bによって閉じられた状態とする。 Also, the user weighs the bread ingredients that are automatically input during the bread manufacturing process and puts them in the container body 42a of the bread ingredient storage container 42. When the user stores the bread ingredients to be stored in the container main body 42a, the container lid 42b is supported by the movable hook 42c so that the opening of the container main body 42a is closed by the container cover 42b.
 なお、パン原料収納容器42に収納されるパン原料としては、例えば、グルテン、ドライイースト等が挙げられる。グルテンの代わりに、例えば小麦粉、増粘剤(グアガム等)及び上新粉のうちの少なくとも1つをパン原料収納容器42に収納するようにしてもよい。また、グルテン、小麦粉、増粘剤、上新粉等は用いずに、例えばドライイーストのみがパン原料収納容器42に収納されるようにしてもよい。更に、場合によっては、例えば食塩、砂糖、ショートニングといった調味料についてもパンの製造工程の途中で自動投入すべく、例えばグルテン、ドライイーストと共に、これらの原料がパン原料収納容器42に収納されるようにしてもよい。この場合には、パン容器80に予め投入しておくパン原料は米粒及び水(単なる水の代わりに、例えばだし汁のような味成分を有する液体、果汁やアルコールを含有する液体等でもよい)となる。 In addition, as a bread raw material accommodated in the bread raw material storage container 42, gluten, dry yeast, etc. are mentioned, for example. Instead of gluten, for example, at least one of flour, thickener (eg, guar gum), and upper fresh powder may be stored in the bread ingredient storage container 42. In addition, for example, only dry yeast may be stored in the bread raw material storage container 42 without using gluten, wheat flour, thickener, super fresh powder or the like. Further, in some cases, for example, salt, sugar and shortening seasonings such as salt, sugar and shortening are stored in the bread ingredient storage container 42 together with, for example, gluten and dry yeast so as to be automatically introduced during the bread manufacturing process. It may be. In this case, the bread raw material previously put into the bread container 80 is rice grains and water (in place of mere water, for example, a liquid having a taste component such as soup stock, a liquid containing fruit juice or alcohol, etc.) Become.
 この後、ユーザは、パン容器80を焼成室30に入れ、更に、パン原料収納容器42を蓋40の所定位置に取り付ける。そして、ユーザは蓋40を閉じ、操作部20によって米粒用製パンコースを選択し、スタートキーを押す。これにより、制御装置120は、米粒を出発原料に用いてパンを製造する米粒用製パンコースの制御動作を開始する。 After this, the user puts the bread container 80 into the baking chamber 30 and further attaches the bread raw material storage container 42 to a predetermined position of the lid 40. Then, the user closes the lid 40, selects the rice grain breadmaking course using the operation unit 20, and presses the start key. Thereby, the control apparatus 120 starts control operation | movement of the bread-making course for rice grains which manufactures bread using a rice grain as a starting material.
 米粒用製パンコースがスタートされると、制御装置120の指令によって浸漬工程が開始される。浸漬工程では、パン容器80に予め投入されたパン原料が静置状態とされ、この静置状態が予め定められた所定時間(本実施形態では30分)維持される。この浸漬工程は、米粒に水を含ませることによって、その後に行われる粉砕工程において、米粒を芯まで粉砕しやすくすることを狙う工程である。 When the bread making course for rice grain is started, the dipping process is started by a command from the control device 120. In the dipping process, the bread raw material previously put in the bread container 80 is set in a stationary state, and the stationary state is maintained for a predetermined time (30 minutes in the present embodiment). This dipping process is a process aimed at making the rice grains easy to be pulverized to the core in the subsequent pulverization process by adding water to the rice grains.
 なお、米粒の吸水速度は水の温度によって変動し、水温が高いと吸水速度が高まり、水温が低いと吸水速度が低下する。このために、浸漬工程の時間は、例えば自動製パン器1が使用される環境温度等によって変動されるようにしてもよい。これにより、米粒の吸水度合いのばらつきを抑制することが可能になる。また、浸漬時間を短時間とするために、シーズヒータ31に通電して、焼成室30の温度が高められるようにしてもよい。 The water absorption rate of rice grains varies depending on the temperature of the water. If the water temperature is high, the water absorption rate increases, and if the water temperature is low, the water absorption rate decreases. For this reason, you may make it fluctuate | variate the time of an immersion process with the environmental temperature etc. in which the automatic bread maker 1 is used, for example. Thereby, it becomes possible to suppress the dispersion | variation in the water absorption degree of a rice grain. Further, in order to shorten the immersion time, the sheathed heater 31 may be energized to increase the temperature of the firing chamber 30.
 また、浸漬工程の初期段階で粉砕ブレード92が回転されるようにしてもよく、更に、その後も、断続的に粉砕ブレード92が回転されるようにしてもよい。このようにすると、米粒の表面に傷をつけることができ、米粒の吸液効率が高められる。 Further, the grinding blade 92 may be rotated at the initial stage of the dipping process, and further, the grinding blade 92 may be intermittently rotated thereafter. If it does in this way, the surface of a rice grain can be damaged, and the liquid absorption efficiency of a rice grain will be improved.
 上記所定時間が経過すると、制御装置120の指令によって、浸漬工程が終了され、米粒を粉砕する粉砕工程が開始される。この粉砕工程では、米粒と水とが含まれる混合物の中で粉砕ブレード92が高速回転(例えば7000~8000rpm)される。この粉砕工程では、制御装置120は、粉砕モータ60を制御してブレード回転軸82を逆方向回転(図8A及び図8Bでは時計方向回転、図9A及び図9Bでは反時計方向回転)させる。ブレード回転軸82の逆方向回転により、粉砕ブレード92は第1の切削刃921a及び第2の切削刃922aが回転方向前方となって回転する。このため、粉砕ブレード92による粉砕機能が得られる。 When the predetermined time has elapsed, the dipping process is terminated by the command of the control device 120, and the pulverizing process for pulverizing the rice grains is started. In this crushing step, the crushing blade 92 is rotated at a high speed (for example, 7000 to 8000 rpm) in a mixture containing rice grains and water. In this crushing step, the control device 120 controls the crushing motor 60 to rotate the blade rotation shaft 82 in the reverse direction (clockwise rotation in FIGS. 8A and 8B, and counterclockwise rotation in FIGS. 9A and 9B). Due to the reverse rotation of the blade rotation shaft 82, the grinding blade 92 rotates with the first cutting blade 921a and the second cutting blade 922a being forward in the rotation direction. For this reason, the grinding function by the grinding blade 92 is obtained.
 なお、粉砕モータ60を用いて粉砕ブレード92を回転させる場合、制御装置120は、クラッチ用ソレノイド73を駆動させて、クラッチ56が動力遮断を行うようにする(図3Aの状態とする)。上述したように、このように制御しないとモータ破損の可能性があるからである。 When rotating the grinding blade 92 using the grinding motor 60, the control device 120 drives the clutch solenoid 73 so that the clutch 56 shuts off the power (the state shown in FIG. 3A). This is because, as described above, there is a possibility that the motor is damaged unless it is controlled in this way.
 粉砕ブレード92を回転させるために、ブレード回転軸82が逆方向回転された場合、ドーム状カバー93もブレード回転軸82の回転に追随して回転を開始するが、次のような動作によってドーム状カバー93の回転はすぐに阻止(停止)される。なお、粉砕ブレード92は、粉砕工程の初期段階では低速で回転され、その後、高速回転されるようにするのが好ましい。 When the blade rotation shaft 82 is rotated in the reverse direction to rotate the grinding blade 92, the dome-shaped cover 93 also starts to rotate following the rotation of the blade rotation shaft 82. The rotation of the cover 93 is immediately blocked (stopped). It is preferable that the pulverizing blade 92 is rotated at a low speed in the initial stage of the pulverization process and then rotated at a high speed.
 粉砕ブレード92を回転させるためのブレード回転軸82の回転に伴うドーム状カバー93の回転方向は、図9A及び図9Bにおいて反時計方向であり、混練ブレード101は、それまで折り畳み姿勢(図9Aに示す姿勢)であった場合には、米粒と水が含まれる混合物から受ける抵抗で開き姿勢(図9Bに示す姿勢)に転じていく。 The rotation direction of the dome-shaped cover 93 accompanying the rotation of the blade rotation shaft 82 for rotating the grinding blade 92 is the counterclockwise direction in FIGS. 9A and 9B, and the kneading blade 101 has been folded until then (see FIG. 9A). In the case of the posture shown in FIG. 9B, the resistance is changed to the open posture (posture shown in FIG. 9B) due to the resistance received from the mixture containing rice grains and water.
 混練ブレード101が開き姿勢になると、第2係合体103bの係合部103bbが第1係合体103aの係合部103abの回転軌道(図8Bの破線参照)から逸脱する。このために、カバー用クラッチ103は、ブレード回転軸82とドーム状カバー93との連結を切り離す。また、開き姿勢になった混練ブレード101は、図9Bに示すように、その一部(正確には、先端側に設けられる緩衝材107)がパン容器80の内側壁(詳細には粉砕効率を向上するためにパン容器80の内壁に設けられた畝状の凸部80b)に当接するために、ドーム状カバー93の回転は阻止(停止)される。なお、上記畝状の凸部80bは必ずしも設けなくてもよく、これが設けられていない場合には、パン容器80の他の部分と緩衝材107が当接することになる。 When the kneading blade 101 is in the open position, the engagement portion 103bb of the second engagement body 103b deviates from the rotation trajectory (see the broken line in FIG. 8B) of the engagement portion 103ab of the first engagement body 103a. For this purpose, the cover clutch 103 disconnects the blade rotation shaft 82 from the dome-shaped cover 93. Further, as shown in FIG. 9B, a part of the kneading blade 101 in the open posture (more precisely, the buffer material 107 provided on the tip side) is formed on the inner wall of the bread container 80 (specifically, the grinding efficiency is improved). The rotation of the dome-shaped cover 93 is prevented (stopped) in order to abut against the bowl-shaped convex portion 80b provided on the inner wall of the bread container 80 for improvement. It should be noted that the bowl-shaped convex portion 80b is not necessarily provided, and when this is not provided, the other portion of the bread container 80 and the cushioning material 107 come into contact with each other.
 緩衝材107の存在により、混練ブレード101とパン容器80とが直接接触しないので、接触部分においてフッ素コーティングが剥がれるのを防止できる。また、粉砕工程においては、粉砕ブレード92の回転中に微振動が発生して、緩衝材107が設けられていない場合には、混練ブレード101とパン容器80とが繰り返し衝突するといった事態が発生し、前述の剥がれのみならず音が発生するといった問題も生じる。この点、本実施形態の自動製パン器1では、緩衝材107の存在によりこの音の発生も抑制できる。 Since the kneading blade 101 and the pan container 80 are not in direct contact with each other due to the presence of the buffer material 107, it is possible to prevent the fluorine coating from being peeled off at the contact portion. Further, in the crushing process, a slight vibration is generated while the crushing blade 92 is rotating, and when the cushioning material 107 is not provided, the kneading blade 101 and the pan container 80 repeatedly collide with each other. In addition to the above-described peeling, there is a problem that sound is generated. In this respect, in the automatic bread maker 1 of this embodiment, the occurrence of this sound can be suppressed due to the presence of the buffer material 107.
 粉砕工程における米粒の粉砕は、先に行われた浸漬工程によって米粒に水が浸み込んだ状態で実行されるために、米粒を芯まで容易に粉砕することができる。粉砕工程における粉砕ブレード92の回転は本実施形態では間欠回転とされる。この間欠回転は、例えば30秒回転して5分間停止するというサイクルで行われ、このサイクルが10回繰り返される。なお、最後のサイクルでは、5分間の停止は行わない。粉砕ブレード92の回転は連続回転としてもよいが、例えばパン容器80内の原料温度が高くなり過ぎることを防止する等の目的のために、間欠回転とするのが好ましい。 The pulverization of the rice grains in the pulverization step is performed in a state in which water is soaked in the rice grains by the previously performed immersion step, so that the rice grains can be easily pulverized to the core. In the present embodiment, the rotation of the pulverizing blade 92 in the pulverization step is intermittent. This intermittent rotation is performed, for example, in a cycle of rotating for 30 seconds and stopping for 5 minutes, and this cycle is repeated 10 times. In the last cycle, the stop for 5 minutes is not performed. The rotation of the crushing blade 92 may be continuous rotation, but for the purpose of, for example, preventing the temperature of the raw material in the bread container 80 from becoming too high, it is preferable to perform intermittent rotation.
 粉砕工程においては、米粒の粉砕が回転停止したドーム状カバー93内で行われるから、米粒がパン容器80の外に飛び散る可能性が低い。 In the pulverization step, the pulverization of the rice grains is performed in the dome-shaped cover 93 that has stopped rotating, and therefore the possibility that the rice grains scatter outside the bread container 80 is low.
 また、ドーム状カバー93内にはリブ93eと窓93dとが設けられており、更に粉砕ブレード92の第2の切削部922が上述の傾斜構造を有している。このために、粉砕ブレード92の逆方向回転により、ドーム状カバー93の下部側(凹部81内に存在する)から、米粒と水とを含む混合物がドーム状カバー93内に入り(吸い込まれ)、粉砕ブレード92による粉砕が行われた後にドーム状カバー93外に出て行く(排出される)という流れがスムーズに行われる。 Further, a rib 93e and a window 93d are provided in the dome-shaped cover 93, and the second cutting part 922 of the grinding blade 92 has the above-described inclined structure. For this purpose, a mixture containing rice grains and water enters (sucks in) the dome-shaped cover 93 from the lower side of the dome-shaped cover 93 (present in the recess 81) by the reverse rotation of the grinding blade 92. After pulverization by the pulverization blade 92, the flow of going out (discharged) out of the dome-shaped cover 93 is smoothly performed.
 詳細には、粉砕ブレード92の第2の切削部922の傾斜構造により、ドーム状カバー93内に入った混合物は、下から上へと流れ易くなっている。また、ドーム状カバー93のリブ93eは、それに向かって押し寄せる混合物に対向する側が凸となるように湾曲しているので、混合物はリブ93eの表面に滞留しにくく、リブ93eに誘導されてスムーズに窓93dの方へ流れていく。なお、ドーム状カバー93外に混合物が排出されるのと入れ替わりに、凹部81の上の空間に存在していた混合物が、凹部81に入り、更に凹部81からガード106の開口部106dを通ってドーム状カバー93内に入いる。 Specifically, the inclined structure of the second cutting part 922 of the grinding blade 92 makes it easy for the mixture that has entered the dome-shaped cover 93 to flow from the bottom to the top. Further, the rib 93e of the dome-shaped cover 93 is curved so that the side facing the mixture pressing toward it is convex, so that the mixture does not easily stay on the surface of the rib 93e, and is smoothly guided by the rib 93e. It flows toward the window 93d. Instead of the mixture being discharged out of the dome-shaped cover 93, the mixture present in the space above the recess 81 enters the recess 81, and further passes through the opening 106d of the guard 106 from the recess 81. It enters into the dome-shaped cover 93.
 また、回転停止状態にあるガード106の開口部106dからドーム状カバー93内に入る米粒は、静止したスポーク106cと回転する粉砕ブレード92との間でせん断されるので、効率良く粉砕が行える。また、ドーム状カバー93に設けられるリブ93eによって、米粒と水とが含まれる混合物の流動(粉砕ブレード92の回転と同方向の流動である)が適度に抑制されるので、米粒の粉砕が効率良く行われる。
 また、粉砕ブレード92の第1の切削刃921aと第2の切削刃922aとは、パン容器80の底面(詳細には凹部81の底面)からの高さが異なる位置を回転するようになっている。このために、2つの切削刃が同一の高さ位置で回転する場合に比べて、米粒と切削刃との接触確率が高められる。すなわち、粉砕ブレード92による粉砕効率が高められた状態で、米粒の粉砕が行える。
Further, the rice grains entering the dome-shaped cover 93 from the opening 106d of the guard 106 in the rotation stopped state are sheared between the stationary spoke 106c and the rotating pulverizing blade 92, so that the pulverization can be performed efficiently. Further, the rib 93e provided on the dome-shaped cover 93 moderately suppresses the flow of the mixture containing rice grains and water (the flow in the same direction as the rotation of the grinding blade 92), so that the rice grains are efficiently crushed. Well done.
Further, the first cutting blade 921a and the second cutting blade 922a of the crushing blade 92 rotate at different positions from the bottom surface of the bread container 80 (specifically, the bottom surface of the recess 81). Yes. For this reason, compared with the case where two cutting blades rotate in the same height position, the contact probability of a rice grain and a cutting blade is raised. That is, rice grains can be pulverized while the pulverization efficiency by the pulverization blade 92 is increased.
 詳細には、ガード106の開口部106dからドーム状カバー93内に吸い込まれた米粒は、最初に第1の切削刃921a(回転軌道面が水平面に略平行となっている)によって切削され易くなっている。そして、ドーム状カバー93内における混合物の流れによって下から上へと押し上げられた米粒は、第2の切削刃922aによって切削され易くなっている。第1の切削刃921a及び第2の切削刃922bは、外周側ほど速く回転して切削能力を発揮し易くなっている。このために、各切削刃921a、922aの外周側は特に鋭利としておくのが好ましい。 Specifically, the rice grains sucked into the dome-shaped cover 93 from the opening 106d of the guard 106 are first easily cut by the first cutting blade 921a (the rotation track surface is substantially parallel to the horizontal plane). ing. Then, the rice grains pushed upward from the bottom by the flow of the mixture in the dome-shaped cover 93 are easily cut by the second cutting blade 922a. The first cutting blade 921a and the second cutting blade 922b are rotated more rapidly toward the outer peripheral side, so that the cutting ability is easily exhibited. For this reason, it is preferable that the outer peripheral sides of the cutting blades 921a and 922a are particularly sharp.
 なお、自動製パン器1においては所定の時間(本実施形態では50分)で粉砕工程が終了するようにしている。しかしながら、米粒の硬さのばらつきや環境条件によって粉砕粉の粒度にばらつきが生じることがある。このため、粉砕工程の終了が、粉砕モータ60の負荷の大きさ(例えば、モータの制御電流等で判断できる)を指標に判断される構成等としても構わない。 In the automatic bread maker 1, the crushing process is completed in a predetermined time (in this embodiment, 50 minutes). However, the grain size of the pulverized powder may vary depending on the hardness of the rice grains and the environmental conditions. For this reason, the end of the pulverization process may be determined based on the magnitude of the load of the pulverization motor 60 (for example, it can be determined by the control current of the motor).
 粉砕工程が終了すると、制御装置120の指令によって休止工程が実行される。この休止工程は、粉砕工程によって上昇したパン容器80内の内容物の温度を下げる冷却期間として設けられている。温度を下げるのは、次に行われる練り工程が、イーストが活発に働く温度(例えば30℃前後)で実行されるようにするためである。本実施形態では、休止工程は所定時間(30分)とされているが、場合によっては、パン容器80の温度等が所定の温度となるまで、休止工程が行なわれる構成等としても構わない。 When the pulverization process is completed, the pause process is executed according to a command from the control device 120. This pause process is provided as a cooling period during which the temperature of the contents in the bread container 80 raised by the crushing process is lowered. The reason for lowering the temperature is that the next kneading step is carried out at a temperature at which the yeast is active (for example, around 30 ° C.). In the present embodiment, the pause process is a predetermined time (30 minutes). However, in some cases, the pause process may be performed until the temperature of the bread container 80 reaches a predetermined temperature.
 休止工程が終了すると、制御装置120の指令によって練り工程が開始される。練り工程の開始にあたって、制御装置120はクラッチ用ソレノイド73を駆動して、クラッチ56が動力伝達を行うようにする(図3Bの状態)。そして、制御装置120は混練モータ50を制御してブレード回転軸82を正方向回転(図8A及び図8Bでは反時計方向回転、図9A及び図9Bでは時計方向回転)させる。 When the pause process is completed, the kneading process is started by a command from the control device 120. At the start of the kneading process, the control device 120 drives the clutch solenoid 73 so that the clutch 56 transmits power (state shown in FIG. 3B). Then, the control device 120 controls the kneading motor 50 to rotate the blade rotating shaft 82 in the forward direction (counterclockwise rotation in FIGS. 8A and 8B and clockwise rotation in FIGS. 9A and 9B).
 ブレード回転軸82を正方向回転させると、粉砕ブレード92も正方向に回転する。この場合、粉砕ブレード92は、第1の切削刃921a及び第2の切削刃922aが回転方向後方となって回転し、粉砕機能を発揮しない。粉砕ブレード92の回転により、粉砕ブレード92の周囲のパン原料が正方向に流動する。それにつられてドーム状カバー93が正方向(図9A及び図9Bでは時計方向)に動くと、混練ブレード101は流動していないパン原料から抵抗を受けて、開き姿勢(図9B参照)から折り畳み姿勢(図9A参照)へと角度を変えて行く。これにより、第2係合体103bの係合部103bbが第1係合体103aの係合部103abの回転軌道(図8Aの破線参照)に干渉する角度となる。そして、カバー用クラッチ103がブレード回転軸82とドーム状カバー93とを連結し、ドーム状カバー93はブレード回転軸82によって本格的に駆動される態勢に入る。ドーム状カバー93と折り畳み姿勢になった混練ブレード101とは、ブレード回転軸82とともに正方向回転する。 When the blade rotation shaft 82 is rotated in the forward direction, the grinding blade 92 is also rotated in the forward direction. In this case, the crushing blade 92 rotates with the first cutting blade 921a and the second cutting blade 922a rearward in the rotation direction, and does not exhibit the crushing function. Due to the rotation of the grinding blade 92, the bread ingredients around the grinding blade 92 flow in the forward direction. Accordingly, when the dome-shaped cover 93 moves in the forward direction (clockwise in FIGS. 9A and 9B), the kneading blade 101 receives resistance from the non-flowing bread ingredients and is folded from the open position (see FIG. 9B). Change the angle to (see FIG. 9A). Thereby, the engaging portion 103bb of the second engaging body 103b has an angle that interferes with the rotation trajectory (see the broken line in FIG. 8A) of the engaging portion 103ab of the first engaging body 103a. Then, the cover clutch 103 connects the blade rotation shaft 82 and the dome-shaped cover 93, and the dome-shaped cover 93 enters a state of being driven in earnest by the blade rotation shaft 82. The dome-shaped cover 93 and the kneading blade 101 in the folded position rotate together with the blade rotation shaft 82 in the forward direction.
 なお、以上に説明したカバー用クラッチ103の連結を確実に行うために、練り工程初期におけるブレード回転軸82の回転は、間欠回転或いは低速回転とするのが好ましい。また、上述のように、混練ブレード101が折り畳み姿勢になると、混練ブレード101の延長上に補完混練ブレード102が並ぶために、混練ブレード101があたかも大型化したかのようになって、パン原料は力強く押される。このため、生地の練り上げをしっかり行える。 In order to surely connect the cover clutch 103 described above, the rotation of the blade rotation shaft 82 at the initial stage of the kneading process is preferably intermittent rotation or low speed rotation. Further, as described above, when the kneading blade 101 is in the folded position, the complementary kneading blade 102 is arranged on the extension of the kneading blade 101, so that the kneading blade 101 is enlarged and the bread raw material is pressed strongly. It is. For this reason, the dough can be kneaded firmly.
 混練ブレード101(この用語は、折り畳み姿勢においては、補完混練ブレード102を含む表現として用いる。以下同様。)の回転は、練り工程の初期においては非常にゆっくりとされ、段階的に速度が速められるように制御装置120によって制御される。混練ブレード101の回転が非常にゆっくりである練り工程の初期段階において、制御装置120は自動投入用ソレノイド16を駆動させて、パン原料収納容器42の可動フック42cが容器蓋42bを支えた状態を解消させる。これにより、容器本体42aの開口が開かれて、例えば、グルテン、ドライイーストといったパン原料がパン容器80内に自動投入される。 The rotation of the kneading blade 101 (this term is used as an expression including the complementary kneading blade 102 in the folded position, the same applies hereinafter) is very slow in the initial stage of the kneading process, and the speed is increased stepwise. Control is performed by the control device 120. In the initial stage of the kneading process in which the kneading blade 101 rotates very slowly, the control device 120 drives the automatic charging solenoid 16 so that the movable hook 42c of the bread ingredient storage container 42 supports the container lid 42b. Let go. Thereby, the opening of the container main body 42a is opened, and for example, bread ingredients such as gluten and dry yeast are automatically charged into the bread container 80.
 上述のように、パン原料収納容器42は、容器本体42a及び容器蓋42bの内部にコーティング層が設けられて滑りがよくなっており、また、内部に凹凸部が設けられないように工夫されている。更に、パッキン42dの配置方法の工夫により、パン原料がパッキン42dに引っ掛かるという事態も抑制されている。このために、パン原料収納容器42にはパン原料がほとんど残ることなく、自動投入が完了する。 As described above, the bread raw material storage container 42 is provided with a coating layer inside the container body 42a and the container lid 42b to improve slipping, and is devised so that there is no uneven portion inside. Yes. Furthermore, the situation where the bread raw material is caught by the packing 42d is also suppressed by the device for arranging the packing 42d. For this reason, the automatic charging is completed with almost no bread ingredients remaining in the bread ingredient storage container 42.
 なお、本実施形態では、パン原料収納容器42に収納されるパン原料が、混練ブレード101が回転している状態で投入されることにしているが、これに限定されず、混練ブレード101が停止している状態で投入されることにしてもよい。ただし、本実施形態のように、混練ブレード101が回転した状態でパン原料が投入される方が、パン原料が均一に分散されるので好ましい。 In this embodiment, the bread ingredients stored in the bread ingredient storage container 42 are charged while the kneading blade 101 is rotating. However, the present invention is not limited to this, and the kneading blade 101 is stopped. You may decide to throw in in the state which is carrying out. However, as in this embodiment, it is preferable to add the bread ingredients while the kneading blade 101 is rotated because the bread ingredients are uniformly dispersed.
 パン原料収納容器42に収納されたパン原料がパン容器80に投入された後は、混練ブレード101の回転によって、パン原料は所定の弾力を有する一つにつながった生地(dough)に練り上げられていく。混練ブレード101が生地を振り回してパン容器80の内壁にたたきつけることにより、混練に「捏ね」の要素が加わることになる。混練ブレード101の回転とともにドーム状カバー93も回転する。ドーム状カバー93が回転すると、ドーム状カバー93に形成されるリブ93eも回転するために、ドーム状カバー93内のパン原料は速やかに窓93dから排出され、混練ブレード101が混練しているパン原料の塊(生地)に同化する。 After the bread ingredients stored in the bread ingredient storage container 42 are put into the bread container 80, the bread ingredients are kneaded into a dough connected to one having a predetermined elasticity by the rotation of the kneading blade 101. Go. When the kneading blade 101 swings the dough and knocks it against the inner wall of the bread container 80, an element of “kneading” is added to the kneading. As the kneading blade 101 rotates, the dome-shaped cover 93 also rotates. When the dome-shaped cover 93 rotates, the rib 93e formed on the dome-shaped cover 93 also rotates, so that the bread material in the dome-shaped cover 93 is quickly discharged from the window 93d and the kneading blade 101 kneads the bread. Assimilate into a lump of material.
 なお、練り工程においては、ドーム状カバー93と共にガード106も正方向に回転する。ガード106のスポーク106cは、正方向回転時、ガード106の中心側が先行しガード106の外周側が後続する形状とされている。このために、ガード106は、正方向に回転することにより、ドーム状カバー93内外のパン原料(パン生地)をスポーク106cで外側に押しやる。これにより、パンを焼き上げた後に廃棄分となる原料の割合を減らすことができる。 In the kneading process, the guard 106 also rotates in the forward direction together with the dome-shaped cover 93. The spoke 106c of the guard 106 has a shape in which the center side of the guard 106 precedes and the outer peripheral side of the guard 106 follows when rotating in the forward direction. For this purpose, the guard 106 rotates in the forward direction to push the bread ingredients (bread dough) inside and outside the dome-shaped cover 93 outward with the spokes 106c. Thereby, the ratio of the raw material used as a waste after baking bread can be reduced.
 また、ガード106の柱106eは、ガード106が正方向に回転するときに回転方向前面となる側面106ebが、上向きに傾斜する構成となっている。このために、混練時、ドーム状カバー93の周囲のパン原料(パン生地)が柱106eの側面106ebで上方に跳ね上げられる。跳ね上げられたパン原料は、上方のパン原料の塊(生地)に同化するために、パンを焼き上げた後に廃棄分となる原料の割合を減らすことができる。 Further, the pillar 106e of the guard 106 is configured such that when the guard 106 rotates in the forward direction, a side surface 106eb that is the front surface in the rotational direction is inclined upward. For this reason, at the time of kneading, the bread material (bread dough) around the dome-shaped cover 93 is splashed upward on the side surface 106eb of the column 106e. Since the boiled bread material is assimilated into the lump (dough) of the upper bread material, the proportion of the raw material that becomes waste after baking the bread can be reduced.
 自動製パン器1においては、練り工程の時間は、所望の弾力を有するパン生地が得られる時間として実験的に求められた所定の時間(本実施形態では10分)が採用されている。ただし、練り工程の時間が一定とされると、環境温度等によってパン生地の出来上がり具合が変動する場合がある。このため、例えば、混練モータ50の負荷の大きさ(例えば、モータの制御電流等で判断できる)を指標に、練り工程の終了時点が判断される構成等としても構わない。 In the automatic bread maker 1, a predetermined time (10 minutes in this embodiment) obtained experimentally as a time for obtaining bread dough having a desired elasticity is employed as the time for the kneading process. However, if the time of the kneading process is constant, the degree of bread dough may vary depending on the environmental temperature or the like. For this reason, for example, a configuration in which the end point of the kneading process is determined based on the magnitude of the load of the kneading motor 50 (for example, it can be determined by the control current of the motor) may be used.
 なお、具材(例えばレーズン、ナッツ、チーズ等)入りのパンが焼かれる場合には、この練り工程の途中で具材が投入されるようにすればよい。 In addition, when bread containing ingredients (for example, raisins, nuts, cheese, etc.) is baked, the ingredients may be introduced during the kneading process.
 練り工程が終了すると、制御装置120の指令によって発酵工程が開始される。この発酵工程では、制御装置120はシーズヒータ31を制御して、焼成室30の温度を、発酵が進む温度(例えば38℃)に維持する。そして、発酵が進む環境下で所定の時間(本実施形態では60分)パン生地が放置される。 When the kneading process is completed, the fermentation process is started by a command from the control device 120. In this fermentation process, the control device 120 controls the sheathed heater 31 to maintain the temperature of the baking chamber 30 at a temperature at which fermentation proceeds (for example, 38 ° C.). Then, the bread dough is left for a predetermined time (in this embodiment, 60 minutes) in an environment in which fermentation proceeds.
 なお、場合によっては、この発酵工程の途中で、混練ブレード101を回転してガス抜きや生地を丸める処理が行われるようにしても構わない。 In some cases, in the middle of this fermentation process, the kneading blade 101 may be rotated to perform degassing or rounding of the dough.
 発酵工程が終了すると、制御装置120の指令によって焼成工程が開始される。制御装置120はシーズヒータ31を制御して、焼成室30の温度を、パン焼きを行うのに適した温度(例えば125℃)まで上昇させる。そして、制御装置120は、焼成環境下で所定の時間(本実施形態では50分)パンを焼くように制御する。焼成工程の終了については、例えば操作部20の液晶表示パネルにおける表示や報知音等によってユーザに知らされる。ユーザは、製パン完了を検知すると、蓋40を開けてパン容器80を取り出して、パンの製造を完了させる。 When the fermentation process is finished, the firing process is started by a command from the control device 120. The control device 120 controls the sheathed heater 31 to increase the temperature of the baking chamber 30 to a temperature suitable for baking (for example, 125 ° C.). Then, the control device 120 performs control so that the bread is baked in a baking environment for a predetermined time (in this embodiment, 50 minutes). The end of the firing process is notified to the user by, for example, a display on the liquid crystal display panel of the operation unit 20 or a notification sound. When the user detects the completion of bread making, the user opens the lid 40 and takes out the bread container 80 to complete the bread production.
 なお、パン容器80内のパンは、例えば、パン容器80の開口を斜め下に向けることで取り出すことができる。そして、このパンの取り出しと同時に、ブレード回転軸82に取り付けられたブレードユニット90もパン容器80から取り出される。ガード106の存在により、このパンの取り出し作業時にユーザは粉砕ブレード92に触れることがなく、ユーザは安全にパンの取り出し作業を行える。パンの底には、ブレードユニット90の混練ブレード101及び補完混練ブレード102(パン容器80の凹部81から上側に突き出ている)の焼き跡が残る。しかし、ドーム状カバー93とガード106が凹部81の中に収容される構成であるために、それらがパンの底に大きな焼き跡を残すようなことは抑制される。 In addition, the bread in the bread container 80 can be taken out by, for example, directing the opening of the bread container 80 obliquely downward. Simultaneously with the removal of the bread, the blade unit 90 attached to the blade rotation shaft 82 is also removed from the bread container 80. Due to the presence of the guard 106, the user does not touch the crushing blade 92 during the bread removal operation, and the user can safely perform the bread removal operation. At the bottom of the bread, burn marks of the kneading blade 101 of the blade unit 90 and the complementary kneading blade 102 (projecting upward from the recess 81 of the bread container 80) remain. However, since the dome-shaped cover 93 and the guard 106 are accommodated in the recess 81, they are prevented from leaving a large burn mark on the bottom of the bread.

 以上に示した自動製パン器の実施形態は本発明の一例であり、本発明が適用される自動製パン器の構成は、以上に示した実施形態に限定されるものではない。
(Other)
The embodiment of the automatic bread maker described above is an example of the present invention, and the configuration of the automatic bread maker to which the present invention is applied is not limited to the embodiment described above.
 例えば、以上に示した実施形態では、第1の切削部921を水平面に対して略平行とし、第2の切削部922を水平面に対して傾いている構成とした。しかし、場合によっては、両方の切削部が水平面に対して略平行となる構成としたり、両方の切削部が水平面に対して傾いている構成としたりしてもよい。この場合でも、第1の切削刃921aと第2の切削刃922aとが、少なくとも一部において、パン容器80の底面からの高さが異なる位置を回転する構成であれば、その構成は本発明の範囲に含まれる。 For example, in the embodiment described above, the first cutting portion 921 is substantially parallel to the horizontal plane, and the second cutting portion 922 is inclined with respect to the horizontal plane. However, depending on the case, both cutting parts may be configured to be substantially parallel to the horizontal plane, or both cutting parts may be configured to be inclined with respect to the horizontal plane. Even in this case, as long as the first cutting blade 921a and the second cutting blade 922a are configured to rotate at a position where the height from the bottom surface of the bread container 80 is different at least in part, the configuration is the present invention. Included in the range.
 ただし、本実施形態のように、一方を水平面に対して略平行とし、他方を水平面に対して傾いた構成とするのが好ましい。このように構成することで、米粒を含む混合物の流れ(循環)をスムーズとしつつ、米粒の粉砕能力を高められる。なお、場合によっては、本実施形態とは逆に、第1の切削部922(水平面に略平行)の第1の切削刃921aが、第2の切削部922(水平面に対して傾斜)の第2の切削刃922aよりも上側を回転する構成を採用しても構わない。このような構成も本発明は含む趣旨である。 However, as in the present embodiment, it is preferable that one is substantially parallel to the horizontal plane and the other is inclined with respect to the horizontal plane. By comprising in this way, the grinding | pulverization capability of a rice grain can be improved, making the flow (circulation) of the mixture containing a rice grain smooth. In some cases, contrary to the present embodiment, the first cutting blade 921a of the first cutting portion 922 (substantially parallel to the horizontal plane) is replaced by the second cutting portion 922 (inclined with respect to the horizontal plane).

 また、以上に示した実施形態においては、緩衝材107は混練ブレード101とは別部材とし、混練ブレード101にリベット109で固定する構成とした。しかし、緩衝材107の固定方法はリベット109による固定に限定されず、場合によっては接着固定等でもよい。また、緩衝材107は、例えばインサート成型等の手法によって、混練ブレード101と一体的に構成しても構わない。 In the embodiment described above, the cushioning material 107 is a separate member from the kneading blade 101 and is fixed to the kneading blade 101 with the rivets 109. However, the fixing method of the buffer material 107 is not limited to the fixing by the rivet 109, and may be adhesive fixing or the like depending on the case. Further, the buffer material 107 may be configured integrally with the kneading blade 101 by a technique such as insert molding.
 また、以上に示した実施形態においては、緩衝材107を混練ブレード101の先端側の一方面に、混練ブレード101の先端から突出するように設けたが、本発明はこの構成に限定されない。すなわち、緩衝材107は、混練ブレード101が開き姿勢となった場合に混練ブレード101とパン容器80とが直接接触しないように設けられればよい。例えば、緩衝材107の厚みを厚くして、緩衝材107が混練ブレード101の先端から突出しない構成とすることも可能である。また、緩衝材107を混練ブレード101の先端に被せる構成(この場合は、混練ブレードの両面に緩衝材が存在する)等としてもよい。 In the embodiment described above, the cushioning material 107 is provided on one surface on the tip side of the kneading blade 101 so as to protrude from the tip of the kneading blade 101, but the present invention is not limited to this configuration. That is, the cushioning material 107 may be provided so that the kneading blade 101 and the bread container 80 do not come into direct contact when the kneading blade 101 is in the open posture. For example, it is possible to increase the thickness of the buffer material 107 so that the buffer material 107 does not protrude from the tip of the kneading blade 101. Further, the buffer material 107 may be configured to cover the tip of the kneading blade 101 (in this case, the buffer material exists on both surfaces of the kneading blade).
 また、以上に示した実施形態においては、緩衝材107を混練ブレード101側に配設する構成としたが、本発明はこの構成に限定される趣旨ではない。すなわち、緩衝材107はパン容器80の内壁に配設される構成としても構わない。この場合も、混練ブレード101とパン容器80とが直接接触するのを防止できる。 In the embodiment described above, the cushioning material 107 is disposed on the kneading blade 101 side, but the present invention is not limited to this configuration. That is, the buffer material 107 may be arranged on the inner wall of the bread container 80. Also in this case, the kneading blade 101 and the bread container 80 can be prevented from coming into direct contact.
 また、以上においては、自動製パン器1によって、米粒を出発原料に用いてパンを製造する場合を示したが、本実施形態の自動製パン器は、例えば小麦粉や米粉を出発原料に用いてパンを製造することもできる。そして、小麦粉や米粉を出発原料に用いてパンを製造する場合には、粉砕ブレード92は不要であるために、以上に示したのとは異なるパン容器(混練ブレードのみがブレード回転軸に取り付けられる従来型のパン容器)を用いるようにしても構わない。 Moreover, in the above, although the case where bread was manufactured using the rice grain as a starting material with the automatic bread maker 1 was shown, the automatic bread maker of this embodiment uses wheat flour or rice flour as a starting material, for example. Bread can also be produced. In the case of producing bread using wheat flour or rice flour as a starting material, the grinding blade 92 is unnecessary, and therefore a bread container different from the one shown above (only the kneading blade is attached to the blade rotation shaft). A conventional bread container) may be used.
 また、以上に示した実施形態では、混練ブレード101とガード106とを備えるドーム状カバー93、及び、粉砕ブレード92が、ブレードユニット90として、ユニット化された構成を採用した。しかし、ドーム状カバー93及び粉砕ブレード92が、別々にブレード回転軸82に取り付けられる構成であっても、本発明は適用可能である。 In the embodiment described above, a configuration in which the dome-shaped cover 93 including the kneading blade 101 and the guard 106 and the crushing blade 92 are unitized as the blade unit 90 is adopted. However, the present invention is applicable even when the dome-shaped cover 93 and the crushing blade 92 are separately attached to the blade rotation shaft 82.
 また、以上に示した実施形態においては、米粒が出発原料として用いられる場合を例に、自動製パン器の構成及び動作が説明された。しかし、本発明は、例えば小麦、大麦、粟、稗、蕎麦、とうもろこし、大豆等の米粒以外の穀物粒が出発原料として用いられる場合にも、適用可能である。 In the embodiment described above, the configuration and operation of the automatic bread maker have been described by taking as an example the case where rice grains are used as a starting material. However, the present invention is also applicable when grain grains other than rice grains such as wheat, barley, straw, buckwheat, buckwheat, corn, and soybean are used as starting materials.
 また、以上に示した米粒用製パンコースの製造フローは例示であり、米粒用製パンコースは他の製造フローとしてもよい。一例を挙げると、粉砕工程後の休止工程は省いてもよい。 Also, the above-described production flow of the rice grain breadmaking course is an example, and the rice grain breadmaking course may be another production flow. As an example, the pause process after the grinding process may be omitted.
 また、以上に示した実施形態では、粉砕ブレード92によって穀物粒が粉砕される場合と、混練ブレード101によってパン生地が練り上げられる場合とで、別々のモータが使用される構成とした。しかし、本発明は、この構成に限定される趣旨ではない。すなわち、例えば1つのモータのみが備えられる構成とし、粉砕ブレード92によって穀物粒が粉砕される場合と、混練ブレード101によってパン生地が練り上げられる場合とで、同一のモータを使用する構成としても構わない。 In the embodiment described above, separate motors are used for the case where the grain is pulverized by the pulverizing blade 92 and the case where the bread dough is kneaded by the kneading blade 101. However, the present invention is not limited to this configuration. That is, for example, only one motor may be provided, and the same motor may be used when the grain is crushed by the pulverizing blade 92 and when the bread dough is kneaded by the kneading blade 101.
 また、以上に示した実施形態では、粉砕工程から始まり、練り工程、発酵工程、焼成工程までを一貫して行う自動製パン器を提示したが、本発明の自動製パン器は、粉砕工程から発酵工程までを、あるいは粉砕工程と練り工程のみを遂行する装置として構成することも可能である。この場合、焼成工程、あるいは発酵工程と焼成工程は外部の機器、例えばオーブン、に委ねることになる。また、本発明の自動製パン器は、家庭用でなく業務用の機器として発展させることもできる。 In the embodiment described above, an automatic bread maker that consistently performs the kneading process, the fermentation process, and the baking process starting from the pulverization process has been presented. It is also possible to configure the apparatus up to the fermentation process, or an apparatus that performs only the pulverization process and the kneading process. In this case, the firing process, or the fermentation process and the firing process, are left to an external device such as an oven. In addition, the automatic bread maker of the present invention can be developed not only for home use but also for business use.
