Description

本発明は、たとえば給湯装置の熱源などとして用いられる燃焼装置に関する。 The present invention relates to a combustion device used, for example, as a heat source for a hot water supply device.

本出願人は、燃焼装置の具体例として、特許文献１に記載のものを先に提案している。
同文献に記載の燃焼装置は、バーナを内部に収容するバーナケースと、このバーナケース内に燃焼用空気を供給するためのファンとを備えている。バーナケースにファンを取付けるための手段としては、ビス止め手段に加え、バーナケースの下部に突設された突出片に、燃焼装置の前後方向に開口した係合用孔部を設けておき、かつこの係合用孔部に、ファンの上部に設けられた係合用突起部を進入させる手段が併用されている。
このような構成において、燃焼装置の前部側においては、バーナケースとファンとをビス止めする一方、燃焼装置の後部側（奥側）においては、係合用孔部と係合用突起部とを嵌合させるようにすれば、燃焼装置の奥側においてビス止めを行なう必要がなくなる。作業者は、燃焼装置の手前側に位置したまま、バーナケースへのファンの取付け、およびその取外し作業を行なうことができる。 The applicant has previously proposed the one described in Patent Document 1 as a specific example of the combustion device.
The combustion device described in the same document includes a burner case for accommodating a burner inside, and a fan for supplying combustion air into the burner case. As a means for attaching the fan to the burner case, in addition to the screw fixing means, the protruding piece projecting from the lower part of the burner case is provided with an engaging hole opened in the front-rear direction of the combustion device, and this is provided. A means for allowing the engaging protrusion provided on the upper part of the fan to enter the engaging hole is also used.
In such a configuration, the burner case and the fan are screwed to each other on the front side of the combustion device, while the engagement hole and the engagement protrusion are fitted on the rear side (back side) of the combustion device. If they are matched, it is not necessary to screw them on the back side of the combustion device. The operator can attach and remove the fan to the burner case while it is located on the front side of the combustion device.

しかしながら、前記従来技術においては、次に述べるように、未だ改善すべき余地があった。 However, in the above-mentioned prior art, there is still room for improvement as described below.

すなわち、バーナケースにファンを取付ける場合、ファンの係合用突起部を、バーナケースの係合用孔部に進入させるが、これらの部位が燃焼装置の奥側に位置する場合、作業者がそれらの突起部や孔部を適切に目視することはできない。このため、係合用突起部を係合用孔部に迅速かつ適切に進入させることが困難となって、その作業に手間取る場合がある。したがって、このような点を適切に改善することが望まれる。 That is, when mounting the fan on the burner case, the engaging protrusions of the fan are made to enter the engaging holes of the burner case, but when these parts are located on the back side of the combustion device, the operator makes those protrusions. It is not possible to properly visually check the parts and holes. For this reason, it becomes difficult to quickly and appropriately allow the engaging protrusion to enter the engaging hole, which may take time and effort. Therefore, it is desired to appropriately improve such a point.

本発明の第３の側面により提供される燃焼装置は、バーナを内部に収容するバーナケースと、このバーナケース内に燃焼用空気を供給するためのファンと、を備えており、前記ファンを前記バーナケースに取付けるための手段として、前記バーナケースおよび前記ファンの一方に設けられ、かつ上下高さ方向に起立した起立片、およびこの起立片に設けられて水平方向としてのｘ方向を向いて開口する係合用孔部と、前記バーナケースおよび前記ファンの他方に設けられ、かつ前記係合用孔部に進入させて前記起立片に係合させるための係合用突起部と、を備えている、燃焼装置であって、前記バーナケースおよび前記ファンは、前記係合用突起部を前記係合用孔部のｘ方向の手前側に配置させたときに、上下高さ方向において互いに嵌合し、かつこの嵌合により、ｘ方向に交差する水平方向としてのｙ方向における前記係合用突起部と前記係合用孔部との位置合わせを可能とする位置合わせ用の被嵌合部および嵌合部と、前記被嵌合部および前記嵌合部を嵌合させたときに上下高さ方向において互いに当接し、かつこの当接により、上下高さ方向における前記係合用突起部と前記係合用孔部との位置合わせを可能とする位置合わせ用の被当接部および当接部と、をさらに備えており、前記起立片のうち、ｙ方向において前記係合用孔部とオーバラップする一部分は、前記起立片の他の部分よりも上下高さ方向の突出幅が部分的に大きくされた突出部とされていることを特徴としている。 The combustion device provided by the third aspect of the present invention includes a burner case for accommodating a burner inside, and a fan for supplying combustion air into the burner case. As a means for attaching to the burner case, an upright piece provided on one of the burner case and the fan and standing upright in the vertical height direction, and an upright piece provided on the upright piece and opened in the x direction as a horizontal direction. Combustion, provided with an engaging hole and an engaging protrusion provided on the other side of the burner case and the fan for entering the engaging hole and engaging with the upright piece. In the device, the burner case and the fan are fitted to each other in the vertical height direction when the engaging protrusion is arranged on the front side in the x direction of the engaging hole, and the fitting is formed.

このような構成によれば、図６を参照して後述する説明からもよく理解できるように、係合用突起部を係合用孔部に進入させるべくこれら両者を接近させる際に、作業者が誤って係合用突起部の位置を上下高さ方向に位置ずれさせた際に、この係合用突起部が起立片の突出部に当接することとなり、係合用突起部が起立片の位置を越えた状態にならないようにすることが可能である。したがって、係合用突起部を係合用孔部に進入させる作業を、より適切に行なえることとなる。一方、起立片の全体の起立高さを大きくしたのでは、全体の大型化を招くが、起立片の一部分のみを突出幅が大きい突出部とすれば、そのような不具合も解消することができる。 According to such a configuration, as can be well understood from the explanation described later with reference to FIG. 6, the operator mistakenly brings the engaging protrusions closer to each other so as to enter the engaging holes. When the position of the engaging protrusion is displaced in the vertical height direction, the engaging protrusion comes into contact with the protruding portion of the standing piece, and the engaging protrusion exceeds the position of the standing piece. It is possible to prevent it from becoming. Therefore, the work of allowing the engaging protrusion to enter the engaging hole can be performed more appropriately. On the other hand, increasing the overall erecting height of the erecting piece leads to an increase in the overall size, but if only a part of the erecting piece is a protruding portion having a large protruding width, such a problem can be solved. ..

As shown in FIG. 2, a portion of the standing piece 10 that overlaps with the engaging hole portion 11 in the lateral width direction is a protruding portion 10a having a larger downward protrusion width than the other portion. As will be described later with reference to FIG. 6, the protruding portion 10a promotes ensuring and facilitating the entry work of the engaging protrusion 21 into the engaging hole 11.

第１および第２の取付け板部１，２の前端部には、バーナケース側およびファン側の取付け部Ｆａ，Ｆｂどうしの取付け固定を図るための被連結部１２および連結部２２が設けられている。これらの被連結部１２および連結部２２は、第１および第２の取付け板部１，２の前端部を下向きまたは上向きに屈曲することにより形成されており、係合用突起部２１を係合用孔部１１に進入させた状態においては、これら被連結部１２および連結部２２どうしを対向接触させた上で、ビスなどの締結部材９を用いて連結することが可能となっている。これら被連結部１２および連結部２２には、締結部材９を挿通させ、または螺合させるための孔部１２ａ，２２ａ（ネジ孔を含む）が設けられている。 The front ends of the first and second mounting plate portions 1 and 2 are provided with a connected portion 12 and a connecting portion 22 for mounting and fixing the mounting portions Fa and Fb on the burner case side and the fan side. There is. These connected portions 12 and connecting portions 22 are formed by bending the front end portions of the first and second mounting plate portions 1 and 2 downward or upward, and the engaging protrusions 21 are formed by engaging holes. In the state of being inserted into the portion 11, the connected portion 12 and the connecting portion 22 can be brought into facing contact with each other and then connected by using a fastening member 9 such as a screw. The connected portion 12 and the connecting portion 22 are provided with holes 12a and 22a (including screw holes) for inserting or screwing the fastening member 9.

第１および第２の取付け板部１，２の横幅方向の両側縁部には、上向きに起立した一対ずつの第１および第２のフランジ部１３，２３が設けられている。これら第１および第２のフランジ部１３，２３は、本発明でいう被嵌合部および嵌合部の一例に相当し、図３に示すように、一対の第１のフランジ部１３には、その下方側から一対の第２のフランジ部２３を嵌合（外嵌）させることが可能である。このような嵌合を図ることにより、第１および第２の取付け板部１，２どうしの横幅方向への相対移動が防止されることに加え、係
合用突起部２１と係合用孔部１１との横幅方向の位置合わせが図られるようになっている。第１および第２のフランジ部１３，２３は、第１および第２の取付け板部１，２の前後方向に断面一様に延びている。図５に示すように、係合用突起部２１を係合用孔部１１の手前に配置させた状態においては、第１および第２のフランジ部１３，２３の後部寄りの一部分どうしを互いに嵌合させることが可能とされている。 A pair of first and second flange portions 13 and 23 standing upward are provided on both side edges of the first and second mounting plate portions 1 and 2 in the lateral width direction. These first and second flange portions 13 and 23 correspond to an example of the fitted portion and the fitting portion in the present invention, and as shown in FIG. 3, the pair of first flange portions 13 has a pair of first flange portions 13. It is possible to fit (outerly fit) the pair of second flange portions 23 from the lower side thereof. By achieving such fitting, in addition to preventing relative movement of the first and second mounting plate portions 1 and 2 in the lateral width direction, the engaging protrusion 21 and the engaging hole 11 Is designed to be aligned in the width direction. The first and second flange portions 13 and 23 extend uniformly in the front-rear direction of the first and second mounting plate portions 1 and 2. As shown in FIG. 5, in a state where the engaging protrusion 21 is arranged in front of the engaging hole 11, the first and second flange portions 13 and 23 are fitted together with each other. It is possible.

第１および第２の取付け板部１，２の横幅方向の両側縁部うち、第１および第２のフランジ部１３，２３よりも内側の領域は、被当接部１４および当接部２４とされている。すなわち、図３（ａ）に示すように、第１および第２のフランジ部１３，２３どうしを嵌合させた際には、第２の取付け板部２の当接部２４（両側縁部）の上面を、第１の取付け板部１の被当接部１４（両側縁部）の下面に当接させることが可能となっている。これら被当接部１４および当接部２４が当接することにより、係合用突起部２１と係合用孔部１１との上下高さ方向の位置合わせが可能となっている。 Of the side edge portions of the first and second mounting plate portions 1 and 2 in the lateral width direction, the regions inside the first and second flange portions 13 and 23 are the contacted portion 14 and the abutted portion 24. Has been done. That is, as shown in FIG. 3A, when the first and second flange portions 13, 23 are fitted to each other, the contact portion 24 (both side edge portions) of the second mounting plate portion 2 is fitted. The upper surface of the above can be brought into contact with the lower surface of the contacted portions 14 (both side edge portions) of the first mounting plate portion 1. When the contacted portion 14 and the abutting portion 24 come into contact with each other, the engagement protrusion 21 and the engagement hole 11 can be aligned in the vertical height direction.

第２の取付け板部２のうち、一対の当接部２４よりも横幅方向内側の領域は、矩形枠状のシール用パッキン８が配される凹状部２５として形成されており、シール用パッキン８は、第１および第２の取付け板部１，２の相互間で圧縮されるように構成されている。凹状部２５は、第２の取付け板部２に一対の起立壁部２６を形成することにより設けられているが、この起立壁部２６の高さ寸法ｈ（凹状部２５の深さ）は、図３（ｂ）に示すシール用パッキン８の非圧縮時の厚み寸法ｔよりも小さくされている。したがって、起立壁部２６の高さ寸法ｈを加減することによって、シール用パッキン８の圧縮度合いを調整することが可能である。好ましくは、起立壁部２６および第２のフランジ部２３は、先端（上端）側が基端側よりも外側配置となるように傾斜している。このような構成によれば、起立壁部２６および第２のフランジ部２３をプレス成形する際に、これらの両者に同一方向の型抜き勾配が設けられることとなり、一工程によって前記両者を同時にプレス成形することができる。なお、シール用パッキン８を配置させるための凹状部２５は、第２の取付け板部２に設けることに代えて、第１の取付け板部１に設けた構成とすることも可能である。 In the second mounting plate portion 2, the region inside the pair of contact portions 24 in the width direction is formed as a concave portion 25 in which the rectangular frame-shaped sealing packing 8 is arranged, and the sealing packing 8 is formed. Is configured to be compressed between the first and second mounting plate portions 1 and 2. The concave portion 25 is provided by forming a pair of upright wall portions 26 on the second mounting plate portion 2, and the height dimension h (depth of the concave portion 25) of the upright wall portion 26 is The thickness of the sealing packing 8 shown in FIG. 3B is smaller than the uncompressed thickness dimension t. Therefore, it is possible to adjust the degree of compression of the sealing packing 8 by adjusting the height dimension h of the upright wall portion 26. Preferably, the upright wall portion 26 and the second flange portion 23 are inclined so that the tip end (upper end) side is arranged outside the base end side. According to such a configuration, when the upright wall portion 26 and the second flange portion 23 are press-formed, both of them are provided with a die-cutting gradient in the same direction, and both of them are pressed at the same time by one step. Can be molded. The concave portion 25 for arranging the sealing packing 8 may be provided in the first mounting plate portion 1 instead of being provided in the second mounting plate portion 2.

次に、前記した構成の燃焼装置Ｃの作用について説明する。 Next, the operation of the combustion device C having the above-described configuration will be described.

まず、図１に示すように、外装ケース５の外部からファン７をバーナケース６に取付ける場合には、図５に示すように、ファン７の第２の取付け板部２を、バーナケース６の第１の取付け板部１の下方に配置させてから、一対ずつの第１および第２のフランジ部１３，２３どうしを嵌合させる。また、これに伴い、一対ずつの被当接部１４および当接部２４どうしを当接させる。このことにより、係合用突起部２１と係合用孔部１１との横幅方向の位置合わせ、および上下高さ方向の位置合わせを行なうことができる。したがって、そのような状態のまま、ファン７をバーナケース６の後部側に移動させれば、係合用突起部２１を係合用孔部１１に進入させ、係合用突起部２１を起立片１０に支持させることができる。既述したように、外装ケース５は前後方向の奥行きが深く、係合用突起部２１や係合用孔部１１を作業者が目視し難い状況にあるが、前記したような作業によれば、係合用突起部２１を係合用孔部１１に進入させる作業が容易化される。 First, as shown in FIG. 1, when the fan 7 is attached to the burner case 6 from the outside of the outer case 5, the second mounting plate portion 2 of the fan 7 is attached to the burner case 6 as shown in FIG. After arranging it below the first mounting plate portion 1, a pair of first and second flange portions 13, 23 are fitted to each other. Along with this, a pair of abutted portions 14 and abutted portions 24 are brought into contact with each other. As a result, the engagement protrusion 21 and the engagement hole 11 can be aligned in the horizontal width direction and in the vertical height direction. Therefore, if the fan 7 is moved to the rear side of the burner case 6 in such a state, the engaging protrusion 21 is made to enter the engaging hole 11, and the engaging protrusion 21 is supported by the standing piece 10. Can be made to. As described above, the exterior case 5 has a deep depth in the front-rear direction, and it is difficult for the operator to visually recognize the engaging protrusion 21 and the engaging hole 11. The work of advancing the fitting protrusion 21 into the engaging hole 11 is facilitated.

なお、前記した作業を行なう際に、所定の作業要領を守らず、第１および第２のフランジ部１３，２３を嵌合させることなく、ファン７を移動させた際には、図６に示すように、係合用突起部２１が係合用孔部１１に進入しない事態が生じる。これに対し、起立片１０には突出部１０ａが設けられているため、前記した事態が生じた場合には、係合用突起部２１が突出部１０ａに当接し、第２の取付け板部２を後退させ過ぎることが適切に防止される。したがって、たとえば係合用突起部２１が起立片１０の下方に配置されたままの不適切な状態で、ファン７がバーナケース６に組み付けられるといったことを適切に防止
することが可能である。 It should be noted that when the fan 7 is moved without observing the predetermined work procedure and without fitting the first and second flange portions 13 and 23 when performing the above-mentioned work, it is shown in FIG. As described above, a situation occurs in which the engaging protrusion 21 does not enter the engaging hole 11. On the other hand, since the upright piece 10 is provided with the protrusion 10a, when the above situation occurs, the engagement protrusion 21 comes into contact with the protrusion 10a, and the second mounting plate portion 2 is moved. Too much retreat is properly prevented. Therefore, for example, it is possible to appropriately prevent the fan 7 from being assembled to the burner case 6 in an inappropriate state in which the engaging protrusion 21 is left below the standing piece 10.

係合用突起部２１を係合用孔部１１に進入させるように設定した後には、締結部材９を用いて被連結部１２と連結部２２とを相互に連結させる。被連結部１２および連結部２２は、外装ケース５内の前寄り部分に位置するため、前記の連結作業は容易に行なうことが可能である。第１および第２の取付け板部１，２は、締結部材９を用いた締結が図られていることに加え、係合用突起部２１が起立片１０に支持され、さらには一対ずつの第１および第２のフランジ部１３，２３が嵌合していることによって横幅方向の位置決め固定も図られているため、バーナケース６にファン７をがたつきのない状態に適切に取付けることが可能である。 After the engaging protrusion 21 is set to enter the engaging hole 11, the connected portion 12 and the connecting portion 22 are connected to each other by using the fastening member 9. Since the connected portion 12 and the connecting portion 22 are located in the front portion in the outer case 5, the above-mentioned connecting operation can be easily performed. The first and second mounting plate portions 1 and 2 are fastened using the fastening member 9, and the engaging protrusions 21 are supported by the upright piece 10, and a pair of first mounting plate portions 1 and 2 are further supported. Since the positioning and fixing in the lateral width direction are also achieved by fitting the second flange portions 13 and 23, the fan 7 can be appropriately mounted on the burner case 6 in a state without rattling. ..
