A nozzle stand 16 for supplying fuel gas to the burner is provided on the front side of the burner unit.
In the box body 3, a controller 17 is provided below and to the right of the combustion device 15. The controller 17 houses an electrical board (not shown) in a box-shaped casing that is rectangular in front view and has a small thickness in the front-rear direction.
An operation panel 40 is attached to the left side of the controller 17 via a fixing member 20. The fixing member 20 is vertically installed between the nozzle stand 16 and the lower folded portion 10 of the bottom plate 8.

固定部材２０は、図３に示すように、前板部２１と、上板部２２と、下板部２３と、側板部２４，２４とを備えている。
前板部２１は、左右幅が上下長さよりも小さい帯板状で、前板部２１の上下には、上四角孔２５及び下四角孔２６が形成されている。上下四角孔２５，２６の間で前板部２１の右端部には、切欠き２７が形成されている。上下四角孔２５，２６の間で前板部２１の前面には、上下方向に延びる矩形状のスポンジシート２８が貼り付けられている。

The front plate part 21 is shaped like a band whose horizontal width is smaller than its vertical length, and an upper square hole 25 and a lower square hole 26 are formed at the top and bottom of the front plate part 21 . A notch 27 is formed at the right end of the front plate portion 21 between the upper and lower square holes 25 and 26. A rectangular sponge sheet 28 extending in the vertical direction is attached to the front surface of the front plate section 21 between the upper and lower square holes 25 and 26.
The upper plate part 22 is bent rearward from the upper end of the front plate part 21 at a right angle. A rectangular escape hole 29 is formed in the upper plate portion 22 . A pair of screw fixing pieces 30, 30 which are bent upward are formed on the left and right sides of the rear end of the upper plate part 22.

下板部２３は、前板部２１の下端からやや後方へ段差を有した状態で前板部２１と平行に下方へ延び、底板８の下折り返し部１０に前方から重なっている。下板部２３の下端で左右方向の中央には、図４にも示すように、後方へ折曲される係止片３１が形成されている。
側板部２４，２４は、前板部２１の左右の両側縁から後方へ折り曲げられて上端から上下方向に延びている。右側の側板部２４は、切欠き２７まで形成されて左側の側板部２４よりも短くなっている。側板部２４，２４の上端は、上板部２２よりも下方に位置して上板部２２の下面に近接している。
この固定部材２０を箱本体３に組み付ける際、まず、下板部２３の係止片３１を底板８の下折り返し部１０の差込孔１２に差し込んで下板部２３を位置決めする。そして、上板部２２に設けたネジ止め片３０，３０を、ノズル台１６にネジ止めする。すると、固定部材２０は、図４に示すように、ノズル台１６と下折り返し部１０との間で上下方向に架設される。このとき前板部２１は、箱本体３の開口と平行に延びている。 The lower plate part 23 extends downward parallel to the front plate part 21 with a step slightly rearward from the lower end of the front plate part 21, and overlaps the lower folded part 10 of the bottom plate 8 from the front. As shown in FIG. 4, a locking piece 31 that is bent rearward is formed at the lower end of the lower plate portion 23 and at the center in the left-right direction.
The side plate parts 24, 24 are bent rearward from both left and right side edges of the front plate part 21 and extend in the vertical direction from the upper end. The right side plate part 24 is formed up to the notch 27 and is shorter than the left side plate part 24. The upper ends of the side plate parts 24, 24 are located below the upper plate part 22 and are close to the lower surface of the upper plate part 22.
When assembling this fixing member 20 to the box body 3, first, the locking piece 31 of the lower plate part 23 is inserted into the insertion hole 12 of the lower folded part 10 of the bottom plate 8 to position the lower plate part 23. Then, the screw fixing pieces 30, 30 provided on the upper plate portion 22 are screwed to the nozzle stand 16. Then, the fixing member 20 is vertically installed between the nozzle stand 16 and the lower folded portion 10, as shown in FIG. At this time, the front plate portion 21 extends parallel to the opening of the box body 3.

操作パネル４０は、パネル台４１と、基板４２と、操作表示部４３とを備えている。パネル台４１は、固定部材２０の前板部２１よりやや小さい左右幅で上下方向に延びる正面視矩形状である。パネル台４１の上下面には、後方へ延びた後、互いに相反する上下方向へ延びる側面視Ｌ字状の上取付片４４及び下取付片４５が形成されている。パネル台４１の前部外周で前面よりもやや後退した位置には、上下左右方向に拡開するフランジ部４６が一体形成されている。パネル台４１の前面には、正面視矩形状の凹部４７が形成されている。
基板４２は、パネル台４１内に収容されて、スイッチ等をパネル台４１の凹部４７の底面に設けた開口から露出させている。パネル台４１の右側面には、ハーネスを電気的に接続するためのコネクタ４８が設けられている。 The operation panel 40 includes a panel stand 41, a substrate 42, and an operation display section 43. The panel stand 41 has a rectangular shape in a front view that extends in the vertical direction and has a horizontal width slightly smaller than the front plate portion 21 of the fixing member 20 . The upper and lower surfaces of the panel stand 41 are formed with an upper mounting piece 44 and a lower mounting piece 45 that are L-shaped in side view and extend rearward and then in opposite vertical directions. A flange portion 46 that expands in the vertical and horizontal directions is integrally formed on the front outer periphery of the panel stand 41 at a position slightly set back from the front surface. A recess 47 having a rectangular shape when viewed from the front is formed on the front surface of the panel stand 41 .
The board 42 is housed within the panel stand 41, and switches and the like are exposed through an opening provided at the bottom of the recess 47 of the panel stand 41. A connector 48 for electrically connecting a harness is provided on the right side of the panel stand 41.

操作表示部４３は、パネル台４１の凹部４７に嵌合する平面視矩形の薄板状で、凹部４７内に保持されている。この状態で操作表示部４３の前面は、パネル台４１の前面と前後方向で同一面上に位置している。操作表示部４３は、基板４２のスイッチをタッチ操作する操作部４９と、温度等を表示する表示部５０とを上下に備えている。
パネル台４１の前部の周囲でフランジ部４６の前面には、スペーサ５１，５１が設けられている。スペーサ５１は、ゴム又は樹脂等で形成される正面視Ｌ字状で、向きを変えて組み合わせることでパネル台４１の周囲を非接触で囲む格好でフランジ部４６の前面に固定されている。スペーサ５１の前面は、パネル台４１及び操作表示部４３の前面よりも後方に位置している。 The operation display section 43 has a rectangular thin plate shape in plan view that fits into the recess 47 of the panel stand 41 and is held within the recess 47 . In this state, the front surface of the operation display section 43 is located on the same plane as the front surface of the panel stand 41 in the front-rear direction. The operation display section 43 includes an operation section 49 for touch-operating switches on the board 42, and a display section 50 for displaying temperature and the like on the upper and lower sides.
Spacers 51, 51 are provided around the front of the panel stand 41 and on the front of the flange portion 46. The spacer 51 is formed of rubber, resin, or the like and has an L-shape when viewed from the front, and is fixed to the front surface of the flange portion 46 so as to surround the panel stand 41 without contact by changing the direction and combining them. The front surface of the spacer 51 is located behind the front surfaces of the panel stand 41 and the operation display section 43.

以上の如く構成された給湯器１において、固定部材２０に操作パネル４０を取り付ける際には、操作パネル４０を、図６（Ａ）に示すように、まずパネル台４１の上取付片４４を前板部２１の前方から上四角孔２５に差し込む。次に、図６（Ｂ）に示すように、上取付片４４の上端を上板部２２の逃がし孔２９に差し込みながら上方へ移動させる。すると、上取付片４４が上四角孔２５の上端に当接して下取付片４５の後方に下四角孔２６が位置する。よって、そのまま操作パネル４０の下部を前板部２１側へ移動させれば、図６（Ｃ）に示すように、下取付片４５を下四角孔２６に挿入することができる。
そして、操作パネル４０から離すと、図４に示すように、下取付片４５が下四角孔２６の下縁に当接し、上下取付片４４，４５の先端がそれぞれ前板部２１の裏側に位置して、操作パネル４０は、前方へ抜け止めされた状態で前板部２１に組み付けられる。
こうして操作パネル４０は、コントローラ１７の左側で前方から重ならない位置に配置される。よって、コントローラ１７とコネクタ４８とのハーネス等の接続を容易に行うことができる。 In the water heater 1 configured as described above, when attaching the operation panel 40 to the fixing member 20, as shown in FIG. Insert into the upper square hole 25 from the front of the plate part 21. Next, as shown in FIG. 6(B), the upper end of the upper mounting piece 44 is inserted into the escape hole 29 of the upper plate part 22 and moved upward. Then, the upper mounting piece 44 comes into contact with the upper end of the upper square hole 25, and the lower square hole 26 is positioned behind the lower mounting piece 45. Therefore, if the lower part of the operation panel 40 is moved toward the front plate part 21 side, the lower mounting piece 45 can be inserted into the lower square hole 26 as shown in FIG. 6(C).
When released from the operation panel 40, the lower mounting piece 45 comes into contact with the lower edge of the lower square hole 26, as shown in FIG. The operation panel 40 is then assembled to the front plate portion 21 in a state where it is prevented from coming off forward.
In this way, the operation panel 40 is arranged on the left side of the controller 17 in a position that does not overlap from the front. Therefore, the harness and the like can be easily connected between the controller 17 and the connector 48.

そして、フロントカバー４を、開口部１４にパネル台４１の前部を嵌合させて箱本体３の前面にネジ止めする。すると、図４及び図５に示すように、固定部材２０の下板部２３は、係止片３１を差込孔１２に差し込んだ状態で、底板８の下折り返し部１０とフロントカバー４のネジ止め部１３との間に挟持される。同時に操作パネル４０は、パネル台４１がスポンジシート２８に押し付けられると共に、スペーサ５１，５１がパネル台４１のフランジ部４６とフロントカバー４との間に挟持されて、前板部２１とフロントカバー４との間に固定される。
開口部１４の内縁には、後方へ折り返されるバーリング部５２が形成されている。バーリング部５２は、フロントカバー４を箱本体３にネジ止めした状態で、パネル台４１とスペーサ５１，５１との間に進入している。パネル台４１は、スポンジシート２８の弾性力によって前方へ付勢されて、フランジ部４６の前面をバーリング部５２の後端に押圧させる。よって、開口部１４から水等の異物が筐体２の内部に侵入しにくくなる。 Then, the front cover 4 is screwed to the front surface of the box body 3 by fitting the front part of the panel stand 41 into the opening 14. Then, as shown in FIGS. 4 and 5, the lower plate part 23 of the fixing member 20 is connected to the lower folded part 10 of the bottom plate 8 and the screw of the front cover 4 with the locking piece 31 inserted into the insertion hole 12. It is held between the stopper part 13 and the stopper part 13. At the same time, the operation panel 40 is constructed such that the panel base 41 is pressed against the sponge sheet 28 and the spacers 51, 51 are sandwiched between the flange portion 46 of the panel base 41 and the front cover 4. is fixed between.
A burring portion 52 that is folded back is formed at the inner edge of the opening 14 . The burring portion 52 enters between the panel stand 41 and the spacers 51, 51 with the front cover 4 screwed to the box body 3. The panel stand 41 is urged forward by the elastic force of the sponge sheet 28, and presses the front surface of the flange portion 46 against the rear end of the burring portion 52. Therefore, foreign substances such as water are less likely to enter the inside of the casing 2 through the opening 14.

上記形態の給湯器１は、燃焼装置１５を収容して前面を開口した箱本体３と、箱本体３の前面に組み付けられるフロントカバー４とからなる筐体２と、前面に操作表示部４３（操作部の一例）を備えて箱本体３内に組み付けられ、フロントカバー４の組み付け状態で、フロントカバー４に設けた開口部１４を介して操作表示部４３が露出する操作パネル４０（操作装置の一例）と、燃焼装置１５を制御するコントローラ１７と、を含んでなる。
そして、筐体２内でコントローラ１７と前後方向に重ならない位置には、上端部が燃焼装置１５に固定され、下端部が箱本体３の底板８に固定されて上下方向に延びる固定部材２０が設けられており、操作パネル４０は、固定部材２０の前面に取り付けられている。
この構成によれば、操作パネル４０をコントローラ１７の前面と重ならない位置に設けることができる。よって、操作パネル４０の操作表示部４３を筐体２の前面に露出させてもハーネス類の取り回しが容易となる。また、固定部材２０を介して操作パネル４０が固定されるため、給湯器１に外部から衝撃が加わった際に操作パネル４０が位置ずれしにくくなる。よって、操作表示部４３の損傷や美観の低下も抑制可能となる。 The water heater 1 of the above configuration includes a housing 2 consisting of a box body 3 that houses a combustion device 15 and has an open front, a front cover 4 assembled to the front of the box body 3, and an operation display section 43 ( An operation panel 40 (an example of an operation unit) is assembled inside the box body 3, and an operation display unit 43 is exposed through an opening 14 provided in the front cover 4 when the front cover 4 is assembled. example) and a controller 17 that controls the combustion device 15.
A fixing member 20 whose upper end is fixed to the combustion device 15 and whose lower end is fixed to the bottom plate 8 of the box body 3 and extends in the vertical direction is located at a position in the housing 2 that does not overlap with the controller 17 in the front-back direction. The operation panel 40 is attached to the front surface of the fixing member 20.
According to this configuration, the operation panel 40 can be provided at a position that does not overlap the front surface of the controller 17. Therefore, even if the operation display section 43 of the operation panel 40 is exposed on the front surface of the housing 2, the harnesses can be easily handled. Furthermore, since the operation panel 40 is fixed via the fixing member 20, the operation panel 40 is less likely to shift position when an external impact is applied to the water heater 1. Therefore, damage to the operation display section 43 and deterioration in appearance can be suppressed.

底板８の前端縁には、箱本体３の前面と平行な下折り返し部１０（折り返し部の一例）が形成されて、下折り返し部１０に、差込孔１２（被係止部の一例）が形成される。一方、固定部材２０は、操作パネル４０が取り付けられる前板部２１と、前板部２１の上端から後方へ折曲されて燃焼装置１５のノズル台１６の前面にネジ止めされるネジ止め片３０（ネジ止め部の一例）を有する上板部２２と、前板部２１の下端に連設される下板部２３とを有する。そして、下板部２３には、差込孔１２に差し込み係止される係止片３１（係止部の一例）が設けられており、下板部２３は、係止片３１を差込孔１２に差し込み係止した状態で、フロントカバー４と下折り返し部１０との間に挟持固定される。
よって、ネジ止めの箇所を削減して固定部材２０を定位置へ容易に固定可能となる。
前板部２１の前面には、操作パネル４０との間に介在されて操作パネル４０を前方へ付勢するスポンジシート２８（弾性部材の一例）が取り付けられている。
よって、寸法誤差によって操作パネル４０が開口部１４から後方に位置ずれする場合でも、スポンジシート２８によって操作パネル４０を前方に付勢してフロントカバー４との一体性を維持し、美観の低下を防止可能となる。また、前板部２１を利用してスポンジシート２８が容易に取り付け可能となる。 A lower folded part 10 (an example of a folded part) parallel to the front surface of the box body 3 is formed on the front edge of the bottom plate 8, and an insertion hole 12 (an example of a locked part) is formed in the lower folded part 10. It is formed. On the other hand, the fixing member 20 includes a front plate part 21 to which the operation panel 40 is attached, and a screw piece 30 that is bent backward from the upper end of the front plate part 21 and screwed to the front surface of the nozzle stand 16 of the combustion device 15. It has an upper plate part 22 having (an example of a screwed part) and a lower plate part 23 connected to the lower end of the front plate part 21. The lower plate part 23 is provided with a locking piece 31 (an example of a locking part) that is inserted into the insertion hole 12 and locked. 12 and in a locked state, it is clamped and fixed between the front cover 4 and the lower folded portion 10.
Therefore, it becomes possible to easily fix the fixing member 20 in a fixed position by reducing the number of places to be screwed.
A sponge sheet 28 (an example of an elastic member) is attached to the front surface of the front plate portion 21 and is interposed between the sponge sheet 28 and the operation panel 40 to urge the operation panel 40 forward.
Therefore, even if the operation panel 40 is displaced backward from the opening 14 due to a dimensional error, the sponge sheet 28 urges the operation panel 40 forward to maintain its integrity with the front cover 4, thereby preventing deterioration in aesthetic appearance. Preventable. Further, the sponge sheet 28 can be easily attached using the front plate portion 21.

以下、本開示の変更例を説明する。
固定部材２０の前板部２１に設ける側板部２４は、図７に示すように、上端を上板部２２の下面に当接させると共に、後端をノズル台１６の前面に当接させてもよい。
このように、前板部２１の左右の側縁に、後方へ折曲されて燃焼装置１５のノズル台１６の前面に当接する側板部２４，２４が形成されると共に、側板部２４，２４の上端が、上板部２２の下面に当接している構造とすれば、落下等の衝撃が前板部２１に加わってもその衝撃を燃焼装置１５側へ逃がして前板部２１の変形等を抑制できる。よって、操作パネル４０の位置ずれや、開口部１４との干渉による操作表示部４３の損傷を防止可能となる。
なお、側板部２４は、前板部２１の左右の側縁でなく何れか一方の側縁にのみ設けてもよい。側板部２４の上端は、上板部２２の下面に近接させてもよい。 Modifications of the present disclosure will be described below.
