Description

本発明は、グリル付コンロに設けられたグリル庫の前面開口部を開閉するグリル扉に関する。   The present invention relates to a grill door that opens and closes a front opening of a grill cabinet provided on a stove with a grill.

従来、この種のグリル扉においては、扉本体の上縁に沿って上縁部材を設けたものが知られている(下記特許文献1参照)。  Conventionally, this type of grill door is known in which an upper edge member is provided along the upper edge of the door body (see Patent Document 1 below).

扉本体は、グリル庫を閉塞する金属製の扉枠と、グリル庫内を視認できるようにガラス板が嵌め込まれた窓部と、グリル庫を開閉する際に使用者が把持するための把持部とを備えている。   The door body is made of a metal door frame that closes the grill cabinet, a window portion in which a glass plate is fitted so that the inside of the grill cabinet can be seen, and a gripping portion for the user to grip when opening and closing the grill cabinet. And.

上縁部材は、合成樹脂等で形成され、高温となったグリル扉の上縁に使用者が誤って触れたとき、熱さによる不快感を軽減するために設けられている。また、扉本体の内部に冷却用の空気を流通させる通気路を形成し、上縁部材に扉本体内部の通気路に連通する冷却用空気の排出孔を設けて、扉本体内部の通気路を通過した空気によって上縁部材を冷却することも行われている。   The upper edge member is made of synthetic resin or the like, and is provided to reduce discomfort due to heat when the user accidentally touches the upper edge of the grill door that has become hot. Also, a ventilation path for circulating cooling air is formed inside the door body, and a cooling air discharge hole communicating with the ventilation path inside the door body is provided in the upper edge member, thereby providing a ventilation path inside the door body. The upper edge member is also cooled by the air that has passed.

特開2012−42106号公報JP 2012-42106 A

しかし、扉本体内部の通気路を通過する冷却用空気は、上縁部材の冷却に先立って扉本体を冷却する。このため、上縁部材の排出孔を通過する冷却用空気は既に温度が高い状態となっており、上縁部材の温度を十分に低下させることができなかった。   However, the cooling air that passes through the air passage inside the door body cools the door body prior to cooling the upper edge member. For this reason, the cooling air passing through the discharge hole of the upper edge member is already in a high temperature state, and the temperature of the upper edge member cannot be sufficiently lowered.

上記の点に鑑み、本発明は、上縁部材の温度上昇を確実に抑えて、使用者が触れた際の熱さによる不快感を軽減することができるグリル扉を提供することを目的とする。   In view of the above, it is an object of the present invention to provide a grill door that can reliably suppress an increase in the temperature of an upper edge member and can reduce discomfort due to heat when touched by a user.

かかる目的を達成するために、本発明は、グリル付コンロに設けられたグリル庫の前面開口部を開閉するグリル扉であって、前記グリル庫の開口部縁に当接して該グリル庫を閉塞する扉本体と、前記扉本体の上端部の全長にわたって設けられた横長形状の上縁部材とを備え、該上縁部材は、その長手方向の両端部に、前記扉本体に連結固定する連結部を備えるものにおいて、前記上縁部材は、前記扉本体の上端部を通気自在の空隙を介して覆う覆部と、前記覆部の長手方向の両端部に設けられて前記扉本体に連結される一対の連結部とを備え、前記扉本体は、その上端の一部から前記上縁部材の前記覆部に向って延出する延出部を備え、前記延出部は、前記連結部と異なる位置で前記覆部の湾曲変形を制限すべく前記上縁部材の前記覆部の一部に係止する形状とされていることにより、前記覆部が湾曲変形したときに該覆部の一部に当接する部分を備えることを特徴とする。 In order to achieve such an object, the present invention is a grill door for opening and closing a front opening of a grill cabinet provided on a stove with a grill, and abuts against the opening edge of the grill cabinet to close the grill cabinet. a door body which, Bei example the upper edge member of oblong shape provided along the entire length of the upper portion of the door body, the upper edge member is at both ends in the longitudinal direction, connecting to connected and fixed to the door body The upper edge member is provided at a cover portion that covers the upper end portion of the door main body through a gas-permeable gap and at both ends in the longitudinal direction of the cover portion, and is connected to the door main body. A pair of connecting portions, and the door body includes an extending portion extending from a part of an upper end thereof toward the cover portion of the upper edge member, and the extending portion is connected to the connecting portion. one of the covering portion of the upper edge member to limit the bending deformation of the covering portion at different positions The Rukoto is an engagement shape to, the covering portion is characterized in that it comprises the abutting portion in a part of said cover portion when the curved deformation.

前記上縁部材は、使用者が直接扉本体の上縁に触れることを防止している。更に、上縁部材の前記覆部が、扉本体の上端を通気自在の空隙を介して覆っている。これにより、扉本体の熱は直接には覆部へ伝達され難くなり、上縁部材の温度上昇を抑えることができる。   The upper edge member prevents the user from directly touching the upper edge of the door body. Furthermore, the said cover part of an upper edge member has covered the upper end of the door main body through the space | gap which can ventilate. Thereby, the heat of a door main body becomes difficult to be directly transmitted to a cover part, and the temperature rise of an upper edge member can be suppressed.

しかし、上縁部材の覆部は、扉本体に連結されている連結部の間で扉本体の上縁に沿った長い範囲に設けられているので、扉本体から伝達される熱が少量であっても、長期に亘るグリル使用により反り等の湾曲変形が生じるおそれがある。そして、このような湾曲変形が上縁部材に生じると、外観上好ましくないだけでなく、扉本体の上端と覆部との間の空隙が狭くなり、当該空隙による断熱作用が低下するおそれがある。   However, since the cover part of the upper edge member is provided in a long range along the upper edge of the door body between the connecting parts connected to the door body, a small amount of heat is transmitted from the door body. However, there is a risk that curved deformation such as warping may occur due to the use of the grill over a long period of time. And when such a curved deformation occurs in the upper edge member, not only is it not preferable in appearance, but the gap between the upper end of the door main body and the cover portion becomes narrow, and there is a possibility that the heat insulation effect due to the gap is reduced. .

そこで、本発明においては、扉本体の上端に前記延出部を設け、延出部を覆部の一部に係止させることにより覆部の湾曲変形を制限した。これにより、上縁部材の温度上昇を確実に抑えることができる。   Therefore, in the present invention, the extension portion is provided at the upper end of the door body, and the bending deformation of the cover portion is limited by locking the extension portion to a part of the cover portion. Thereby, the temperature rise of an upper edge member can be suppressed reliably.

以上のように、本発明によれば、上縁部材の温度上昇を確実に抑えて、使用者が触れた際の熱さによる不快感を軽減することができる。   As described above, according to the present invention, it is possible to reliably suppress an increase in the temperature of the upper edge member and to reduce discomfort due to heat when the user touches it.

また、本発明において、前記扉本体は、窓部が形成された金属製の扉枠と、前記窓部の前面に取り付けられたガラス板とを備え、前記上縁部材は、前記扉枠の上部に取り付けられ、前記扉枠は、前記ガラス板の上端側の外面を当該外面から所定の距離を存して覆うことにより前記ガラス板の上端側の外面と前記扉枠との間に空隙を形成する空隙形成部を備えることを特徴とする。   Further, in the present invention, the door body includes a metal door frame in which a window portion is formed and a glass plate attached to the front surface of the window portion, and the upper edge member is an upper portion of the door frame. The door frame covers the outer surface on the upper end side of the glass plate at a predetermined distance from the outer surface, thereby forming a gap between the outer surface on the upper end side of the glass plate and the door frame. It is characterized by including a gap forming portion.

窓部に取り付けられたガラス板は、グリル庫の内部を視認可能とするものであるが、グリル庫の使用によって蓄熱し易い。本発明は、扉枠に前記空隙形成部を設けたことにより、ガラス板の上端側の外面と扉枠との間の空隙を空気による断熱層とすることができる。これによれば、扉枠からガラス板への熱の伝達が抑えられ、ガラス板からの輻射熱も低減させることができる。よって、扉枠の上部に取り付けられている上縁部材に対するガラス板からの輻射熱の影響を小さくして、上縁部材の温度上昇を確実に抑えることができる。   The glass plate attached to the window allows the inside of the grill to be visible, but heat is easily stored by using the grill. In the present invention, by providing the gap forming portion in the door frame, the gap between the outer surface on the upper end side of the glass plate and the door frame can be made into a heat insulating layer by air. According to this, transmission of heat from the door frame to the glass plate can be suppressed, and radiant heat from the glass plate can also be reduced. Therefore, the influence of the radiant heat from the glass plate on the upper edge member attached to the upper part of the door frame can be reduced, and the temperature rise of the upper edge member can be reliably suppressed.

本発明の一実施形態を図面に基づいて説明する。図1に示すように、本実施形態のグリル扉1は、グリル付コンロ2の前面側の中央部に設けられ、グリル付コンロ2の内部に設けられたグリル庫3(図3に一部を示す)の前方を開閉するものである。   An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the grill door 1 of this embodiment is provided in the center part of the front side of the stove 2 with a grill, and the grill store | warehouse | chamber 3 (a part is shown in FIG. 3) provided in the inside of the stove 2 with a grill. Open and close the front of (shown).

グリル付コンロ2は、コンロ本体4の上部にコンロ天板5が設けられ、コンロ天板5にはその上方に露出するコンロバーナ6,7が設けられている。グリル付コンロ2の前面側におけるグリル扉1の両側には、各コンロバーナ6,7の点火、火力調整、及び消火を行うための操作つまみ8,9や、グリル庫3内の図示しないグリルバーナの点火、火力調整、及び消火を行うための操作つまみ10が設けられている。   In the stove 2 with grill, a stove top plate 5 is provided on the top of the stove body 4, and the stove top plate 5 is provided with stove burners 6 and 7 exposed above. On both sides of the grill door 1 on the front side of the stove 2 with grill, there are operating knobs 8 and 9 for igniting, adjusting the thermal power and extinguishing the stove burners 6 and 7 and a grill burner (not shown) in the grill cabinet 3. An operation knob 10 is provided for performing ignition, thermal power adjustment, and fire extinguishing.

グリル扉1は、図2及び図3に示すように、扉本体11と、上縁部材12とを備えている。扉本体11は、鉄やステンレス等の金属により形成された扉枠13と、耐熱合成樹脂製の前パネル14と、矩形状のガラス板15とを備えている。   As shown in FIGS. 2 and 3, the grill door 1 includes a door body 11 and an upper edge member 12. The door body 11 includes a door frame 13 made of a metal such as iron or stainless steel, a front panel 14 made of heat-resistant synthetic resin, and a rectangular glass plate 15.

扉枠13には、グリル庫3の内部を視認可能とする窓部16が形成されている。扉枠13の前面には、ガラス板15が嵌め込み支持されている。ガラス板15はグリル庫3の内部を視認可能な状態で窓部16の前面を覆っている。   The door frame 13 is formed with a window portion 16 that allows the inside of the grill cabinet 3 to be visually recognized. A glass plate 15 is fitted and supported on the front surface of the door frame 13. The glass plate 15 covers the front surface of the window portion 16 in a state where the inside of the grill cabinet 3 is visible.

扉枠13の窓部16の下方には内面板17が一体に設けられている。前パネル14は、ガラス板15の下方に位置して扉枠13の内面板17に複数のねじ部材18により連結されている。   An inner surface plate 17 is integrally provided below the window portion 16 of the door frame 13. The front panel 14 is positioned below the glass plate 15 and connected to the inner surface plate 17 of the door frame 13 by a plurality of screw members 18.

図1及び図3に示すように、前パネル14の前面側には把持部19が設けられており、この把持部19を把持してグリル扉1の開閉操作が行えるようになっている。なお、グリル扉1には、図示しないが、グリル庫3内に収容する焼き網及び汁受け皿を支持する支持フレームの前端が連結されている。グリル扉1の開閉操作により焼き網及び汁受け皿の出し入れが行われ、焼き網には魚等の調理物が載置される。   As shown in FIGS. 1 and 3, a grip portion 19 is provided on the front side of the front panel 14, and the grill door 1 can be opened and closed by gripping the grip portion 19. Although not shown, the grill door 1 is connected to the front end of a support frame that supports the grill and the soup pan received in the grill cabinet 3. By opening and closing the grill door 1, the grill net and the juice tray are put in and out, and a cooked item such as fish is placed on the grill net.

グリル庫3から焼き魚等を取り出すためにグリル扉1を引き出すときには、使用者の手等が誤ってグリル扉1の上縁に触れるおそれがある。そこで、使用者がグリル扉1の上縁に触れたときの熱さによる不快感を軽減するため、扉本体11の上縁の全長にわたって上縁部材12が設けられている。   When pulling out the grill door 1 to take out grilled fish or the like from the grill cabinet 3, the user's hand or the like may accidentally touch the upper edge of the grill door 1. Therefore, in order to reduce discomfort due to heat when the user touches the upper edge of the grill door 1, an upper edge member 12 is provided over the entire upper edge of the door body 11.

上縁部材12は、ポリフェニレンサルファイド樹脂(PPS)等の耐熱性を有する合成樹脂により形成されている。上縁部材12は、図2及び図4に示すように、長手方向の両端部の夫々に連結部20を備え、ねじ部材21によって扉枠13の上縁の両端部に連結固定されている。なお、上縁部材12は、合成樹脂製のものを採用する以外に、セラミック等の高い耐熱性を有する材料により形成されているものを採用してもよい。   The upper edge member 12 is formed of a synthetic resin having heat resistance such as polyphenylene sulfide resin (PPS). As shown in FIGS. 2 and 4, the upper edge member 12 includes connecting portions 20 at both ends in the longitudinal direction, and is connected and fixed to both ends of the upper edge of the door frame 13 by screw members 21. The upper edge member 12 may be made of a material having high heat resistance, such as ceramic, in addition to the synthetic resin member.

上縁部材12の両連結部20間には、扉枠13の上端部(上端面及び上部前面)を通気自在の空隙を介して覆う覆部22が形成されている。覆部22の前端縁には起立壁23が形成されている。   Between the connecting portions 20 of the upper edge member 12, a cover portion 22 that covers the upper end portion (upper end surface and upper front surface) of the door frame 13 via a ventilable gap is formed. A standing wall 23 is formed on the front edge of the cover 22.

扉枠13の上端部と覆部22との間の空隙によって空気による断熱性が得られるだけでなく、扉枠13と覆部22との間を空気が通過することにより冷却作用も得られる。更に、使用者が上縁部材12に接触しても、起立壁23の上縁に触れたときの接触面積が小さく、グリル使用時に熱さを感じる不快感を軽減することができる。   The air gap between the upper end portion of the door frame 13 and the cover portion 22 not only provides heat insulation by air, but also allows the cooling effect to be obtained by passing air between the door frame 13 and the cover portion 22. Furthermore, even when the user touches the upper edge member 12, the contact area when the upper edge of the upright wall 23 is touched is small, and the unpleasant feeling of heat when using the grill can be reduced.

上縁部材12は、図3に示すように、扉本体11の前面となるガラス板15より前方に張り出している。これにより、ガラス板15の前面に沿って上昇する空気を扉枠13と覆部22との間の空隙に円滑に取り込むことができ、空気流による上縁部材12の冷却効果が向上する。   As shown in FIG. 3, the upper edge member 12 projects forward from the glass plate 15 that is the front surface of the door body 11. Thereby, the air which raises along the front surface of the glass plate 15 can be smoothly taken in into the space | gap between the door frame 13 and the cover part 22, and the cooling effect of the upper edge member 12 by an airflow improves.

また、扉枠13における窓部16の上側部分は、ガラス板15の上端側の外面を所定の距離を存して覆っている。これにより、ガラス板15の上端側の外面と扉枠13における窓部16の上側部分との間には空隙が形成され(空隙形成部24)、この空隙形成部24により、ガラス板15の上部には空気による比較的大きな断熱層が形成される。扉枠13における窓部16の上側部分とガラス板15の上端側の外面との距離は、本実施形態においてはガラス板15の厚み寸法と同等以上としたが、これに限るものでなく、扉本体11の外観が維持される範囲で十分な空気断熱層が得られる空隙形成部24が形成できればよい。   Moreover, the upper part of the window part 16 in the door frame 13 covers the outer surface on the upper end side of the glass plate 15 with a predetermined distance. Thus, a gap is formed between the outer surface on the upper end side of the glass plate 15 and the upper portion of the window portion 16 in the door frame 13 (gap forming portion 24). A relatively large heat insulating layer is formed by air. The distance between the upper portion of the window 16 in the door frame 13 and the outer surface on the upper end side of the glass plate 15 is equal to or greater than the thickness dimension of the glass plate 15 in the present embodiment, but is not limited thereto. It suffices if the air gap forming part 24 can be formed so that a sufficient air insulation layer can be obtained within a range in which the appearance of the main body 11 is maintained.

空隙形成部24の空気断熱層は、扉枠13からガラス板15への熱の伝達を低減させる。このため、ガラス板15の上端部の温度上昇が抑制され、ガラス板15からの輻射熱が上縁部材12に届き難くなるので、グリル使用時の上縁部材12の温度上昇を抑えることができる。   The air insulation layer of the gap forming part 24 reduces heat transfer from the door frame 13 to the glass plate 15. For this reason, since the temperature rise of the upper end part of the glass plate 15 is suppressed and the radiant heat from the glass plate 15 becomes difficult to reach the upper edge member 12, the temperature rise of the upper edge member 12 at the time of grill use can be suppressed.

図3及び図5に示すように、上縁部材12が取り付けられている扉枠13の上端部には、ガラス板15の上方で前方に向かって延びる延出部25が形成されている。延出部25はガラス板15よりも前方位置で下方に屈曲し、延出部25の下方に向けた先端には左右方向幅が延出部25よりも小さい爪片26が形成されている。   As shown in FIGS. 3 and 5, an extended portion 25 extending toward the front above the glass plate 15 is formed at the upper end portion of the door frame 13 to which the upper edge member 12 is attached. The extending portion 25 is bent downward at a position ahead of the glass plate 15, and a claw piece 26 having a width in the left-right direction smaller than that of the extending portion 25 is formed at the front end of the extending portion 25.

上縁部材12の覆部22はその裏面に小突起27(本発明における延出部25を係止する覆部22の一部に相当する)を一体に備えている。小突起27には、扉枠13の延出部25の爪片26を上方から差し込んで係止する差込孔28が形成されている。グリル扉1の製造工程において、爪片26を差込孔28に差し込む作業は、連結部20を扉枠13に連結する前工程で行われる。   The cover portion 22 of the upper edge member 12 is integrally provided with a small protrusion 27 (corresponding to a part of the cover portion 22 that locks the extending portion 25 in the present invention) on the back surface thereof. The small protrusion 27 is formed with an insertion hole 28 for inserting and locking the claw piece 26 of the extending portion 25 of the door frame 13 from above. In the manufacturing process of the grill door 1, the operation of inserting the claw pieces 26 into the insertion holes 28 is performed in a previous process of connecting the connecting portion 20 to the door frame 13.

なお、本実施形態では、覆部22の裏面に備える小突起27に差込孔28を形成して爪片26を係止させるようにしたが、覆部22の裏面に後方に向って水平に張出す部分が形成されているときには、この張り出し部分に差込孔28のような孔を形成して爪片26を係止させてもよい。   In the present embodiment, the insertion holes 28 are formed in the small protrusions 27 provided on the back surface of the cover portion 22 so that the claw pieces 26 are locked. However, the back surface of the cover portion 22 is horizontally directed backward. When the protruding portion is formed, a hole such as the insertion hole 28 may be formed in the protruding portion to lock the claw piece 26.

図3及び図6に示すように、差込孔28に爪片26を差し込んだ状態では、差込孔28の内面と爪片26との間に極僅かな隙間が形成されている。これにより、扉枠13の熱が上縁部材12に伝達されるのをできるだけ抑えている。そして、覆部22が熱により湾曲変形した場合には、変形量が小さいうちに覆部22の裏面の小突起27が延出部25に当接したり、差込孔28の内面に爪片26が当接したりして、それ以上の変形が制限される。   As shown in FIGS. 3 and 6, in a state where the claw piece 26 is inserted into the insertion hole 28, a very slight gap is formed between the inner surface of the insertion hole 28 and the claw piece 26. Thereby, the heat of the door frame 13 is suppressed from being transmitted to the upper edge member 12 as much as possible. When the cover portion 22 is curved and deformed by heat, the small protrusion 27 on the back surface of the cover portion 22 comes into contact with the extension portion 25 while the deformation amount is small, or the claw piece 26 is formed on the inner surface of the insertion hole 28. Or the like, and further deformation is limited.

具体的には、覆部22の中央部分が上方に盛り上がるように湾曲変形が生じた場合には、この変形に追従して覆部22の裏面の小突起27が上昇するが、小突起27が僅かに上昇したところで延出部25の爪片26より幅広の先端縁に当接して、覆部22の中央部分が上方に盛り上がるような湾曲変形が抑えられる。覆部22の中央部分が後方(扉枠13側)に凹むような湾曲変形が生じた場合には、この変形に追従して覆部22の裏面の小突起27が後方に移動するが、小突起27が僅かに移動したところで差込孔28の内面が爪片26に接するので、覆部22の中央部分が後方に凹むように湾曲変形が抑えられる。これにより、覆部22の中央部分が後方に凹むように大きく湾曲変形が生じる事態が防止でき、覆部22と扉枠13との間の空隙が狭くなることが防止できる。   Specifically, when a curved deformation occurs so that the central portion of the cover portion 22 rises upward, the small protrusion 27 on the back surface of the cover portion 22 rises following this deformation. When it slightly rises, it is brought into contact with the leading edge that is wider than the claw piece 26 of the extending portion 25, and curving deformation such that the central portion of the cover portion 22 rises upward is suppressed. When a curved deformation occurs such that the central portion of the cover portion 22 is recessed rearward (door frame 13 side), the small protrusion 27 on the back surface of the cover portion 22 moves rearward following this deformation. Since the inner surface of the insertion hole 28 comes into contact with the claw piece 26 when the protrusion 27 is slightly moved, the bending deformation is suppressed so that the central portion of the cover portion 22 is recessed backward. As a result, it is possible to prevent a situation in which the curved portion is greatly deformed so that the central portion of the cover portion 22 is recessed backward, and the gap between the cover portion 22 and the door frame 13 can be prevented from becoming narrow.

なお、本実施形態においては、差込孔28に爪片26を差し込んだ状態で差込孔28の内面と爪片26との間に極僅かな隙間が形成されるように構成したが、これに限るものではなく、差込孔28と爪片26とを互いに接する形状に形成してもよい。この場合には、覆部22に湾曲変形が生じなくても差込孔28に接する爪片26から小突起27への熱の伝達が生じるが、覆部22の熱による湾曲変形を強固に抑えることができる。   In the present embodiment, a very small gap is formed between the inner surface of the insertion hole 28 and the claw piece 26 in a state where the claw piece 26 is inserted into the insertion hole 28. The insertion hole 28 and the claw piece 26 may be formed in a shape in contact with each other. In this case, heat is transmitted from the claw piece 26 contacting the insertion hole 28 to the small protrusion 27 even if the cover 22 is not curvedly deformed, but the curved deformation due to the heat of the cover 22 is strongly suppressed. be able to.

以上の構成により、本実施形態のグリル扉1においては、扉本体11の扉枠13及びガラス板15と上縁部材12の覆部22との間に広範囲にわたる空隙が確保されて相互の接触部分が極めて少ないだけでなく、上縁部材12の変形によって当該空隙が狭くなることも防止されている。これにより、上縁部材12の温度上昇を確実に抑えることができ、上縁部材12に使用者が触れたときの熱さによる不快感を軽減することができる。   With the above configuration, in the grill door 1 of the present embodiment, a wide space is secured between the door frame 13 and the glass plate 15 of the door main body 11 and the cover portion 22 of the upper edge member 12, so that mutual contact portions are obtained. In addition to being extremely small, the gap is prevented from becoming narrow due to the deformation of the upper edge member 12.
