Reference numerals 14 and 14 denote installation brackets attached to the upper and lower sides of the back plate 6.

フロントカバー７は、正面視が筐体２と略同形の縦長矩形状で、筐体２のフランジ部１２，１２・・を含む前面に嵌合する外周部１５と、外周部１５の内側から全体的に前方へ膨出する正面視縦長矩形状の膨出部１６とを備えて前後に厚みを有する形状となっている。膨出部１６の前面上側には、排気部１１の前面に設けた横長の排気口１１ａが嵌合する長孔１７が形成され、膨出部１６の前面下側と側方とには、吸気孔１８，１８・・が形成されている。
また、膨出部１６の上部には、図４に示すように、左右両端を除く上辺部分が下降して外周部１５の上側を上下に幅広とする正面視横長台形状の上凹部１９が形成され、同様に膨出部１６の下部にも、左右両端を除く下辺部分が上昇して外周部１５の下側を上下に幅広とする正面視横長台形状の下凹部２０が形成されている。上凹部１９と下凹部２０とによって幅広となる外周部１５の上下には、フランジ部１２のネジ孔１３，１３に対応するネジ止め部としての左右一対のネジ止め孔２１，２１がそれぞれ形成されている。 The front cover 7 is a vertically-long rectangular shape having substantially the same shape as the housing 2 in a front view, and the entire outer periphery 15 fitted to the front including the flanges 12, 12. It has a bulging portion 16 having a longitudinally long rectangular shape in a front view and bulging forward, and has a thickness in front and back. A long hole 17 is formed on the front upper side of the bulging portion 16 into which the horizontally long exhaust port 11a provided on the front surface of the exhausting portion 11 is fitted. Holes 18, 18 are formed.
Further, as shown in FIG. 4, the upper recess 19 is formed in the upper part of the bulging portion 16 so as to widen the upper side of the outer peripheral portion 15 by lowering the upper side portion excluding both left and right ends. Similarly, also in the lower part of the bulging part 16, the lower concave part 20 having a front view horizontally long trapezoidal shape is formed in which the lower side portion excluding the left and right ends rises to widen the lower side of the outer peripheral part 15 vertically. A pair of left and right screwing holes 21 and 21 as screwing portions corresponding to the screw holes 13 and 13 of the flange portion 12 are respectively formed on the upper and lower sides of the outer peripheral portion 15 which is widened by the upper concave portion 19 and the lower concave portion 20. ing.

さらに、上凹部１９及び下凹部２０に隣接する膨出部１６の上下面には、正面視が台形状の被係止部２２，２２が、それぞれ左右一対ずつ切り起こし形成されている。
このため、膨出部１６の上下面には、被係止部２２，２２の切り起こしに伴う透孔２３，２３が形成されることになるが、フロントカバー７の裏面には、図７，８に示すように、上凹部１９の後側で外周部１５の裏面（ネジ止め孔２１，２１は除く）を覆う上板２５と、上凹部１９の下側で膨出部１６の下側内面を覆う下板２６とからなるシール部材としての断面Ｌ字状のシール板２４が貼着されて、下板２６に設けた左右一対の延設片２７，２７が、透孔２３，２３を下方から閉塞している。なお、下凹部２０側では、透孔２３，２３は膨出部１６の下面に開口するため、シール板２４を設けなくても雨水等が浸入するおそれはないが、ここにもシール板２４を貼着して差し支えない。 Further, on the upper and lower surfaces of the bulging portion 16 adjacent to the upper concave portion 19 and the lower concave portion 20, the left and right engaged portions 22, 22 having a trapezoidal shape in a front view are respectively cut and raised.
For this reason, through holes 23 and 23 are formed on the upper and lower surfaces of the bulging portion 16 along with cutting and raising of the engaged portions 22 and 22. As shown in FIG. 8, an upper plate 25 that covers the back surface (except for the screw holes 21 and 21) of the outer peripheral portion 15 on the rear side of the upper recess 19 and the lower inner surface of the bulging portion 16 on the lower side of the upper recess 19. An L-shaped seal plate 24 as a seal member consisting of a lower plate 26 covering the upper and lower plates 26 is attached, and a pair of left and right extended pieces 27 provided on the lower plate 26 lower the through holes 23 and 23. It is blocked from In the lower recess 20 side, since the through holes 23 and 23 open on the lower surface of the bulging portion 16, there is no risk that rain water etc. will infiltrate without providing the sealing plate 24, but the sealing plate 24 It may be stuck.

そして、膨出部１６の上凹部１９と下凹部２０とには、樹脂カバー３０，３０がそれぞれ着脱可能に装着されている。
この樹脂カバー３０は、合成樹脂の一体成形品で、図５，６に示すように、上凹部１９と下凹部２０との正面視形状に対応する横長台形状の前板部３１と、前板部３１の長辺へ直角に連設され、平面視が帯状の平板部３２とを有し、前板部３１と平板部３２との間の内面には、上下方向の補強リブ３３，３３・・が、左右に所定間隔をおいて４枚設けられている。また、前板部３１の裏面には、後方へ突出して端部寄りの上面に凸部３５をそれぞれ形成した左右一対の係止部としての係止片３４，３４が設けられている。この係止片３４，３４は、膨出部１６の被係止部２２，２２にそれぞれ前方から差し込み可能となっている。さらに、平板部３２における係止片３４，３４の上方位置には、樹脂カバー３０を取り外す際の操作位置を示す表示部３６，３６が、後端へ行くに従って深くなる傾斜を有して凹設されている。 The resin covers 30, 30 are detachably mounted on the upper recess 19 and the lower recess 20 of the bulging portion 16, respectively.
The resin cover 30 is an integrally molded product of synthetic resin, and as shown in FIGS. 5 and 6, a laterally long trapezoidal shaped front plate portion 31 corresponding to the front view shape of the upper recess 19 and the lower recess 20, and a front plate It has a flat plate portion 32 which is continuously provided at right angles to the long side of the portion 31 and has a strip-like flat surface view in plan view, and on the inner surface between the front plate portion 31 and the flat plate portion 32, reinforcing ribs 33, 33 · · · in the vertical direction. However, there are four provided at predetermined intervals on the left and right. Further, on the back surface of the front plate portion 31, locking pieces 34, 34 as a pair of left and right locking portions are provided, which project rearward and form convex portions 35 on the upper surface close to the end. The locking pieces 34 can be inserted into the engaged portions 22 of the bulging portion 16 from the front respectively. Furthermore, at the upper position of the locking pieces 34, 34 in the flat plate portion 32, the display portions 36, 36 indicating the operation position when removing the resin cover 30 are recessed with an inclination that becomes deeper toward the rear end It is done.

以上の如く構成された給湯器１において、フロントカバー７を取り付ける場合、まず、樹脂カバー３０を装着する前のフロントカバー７を筐体２の前面に組み付け、外周部１５の上下のネジ止め孔２１，２１を介してそれぞれネジ３７，３７（図８）をフランジ部１２のネジ孔１３，１３にねじ込むことで固定する。
その後、上凹部１９に対し、樹脂カバー３０を、平板部３２を上にして係止片３４，３４を被係止部２２，２２に差し込むようにして前方から組み付ける。すると、図８に示すように、凸部３５が被係止部２２を越えるまで係止片３４が差し込まれて弾性係止すると共に、平板部３２が外周部１５の前面に当接し、各補強リブ３３が外周部１５の前面及び膨出部１６の上面に当接する位置で固定される。この位置で前板部３１は、前面が膨出部１６の前面と略同一面上にあって上凹部１９を前方から覆い、平板部３２は上凹部１９を上方から覆う。よって、上側の樹脂カバー３０によってネジ３７，３７は隠されることになる。 In the water heater 1 configured as described above, when the front cover 7 is attached, first, the front cover 7 before attaching the resin cover 30 is assembled to the front surface of the housing 2, and upper and lower screwing holes 21 of the outer peripheral portion 15 , 21 are fixed by screwing screws 37, 37 (FIG. 8) into the screw holes 13, 13 of the flange portion 12, respectively.
Thereafter, the resin cover 30 is assembled to the upper recess 19 from the front so that the locking pieces 34 are inserted into the locking portions 22 with the flat plate portion 32 up. Then, as shown in FIG. 8, the locking piece 34 is inserted until the convex portion 35 exceeds the locked portion 22 and is elastically locked, and the flat plate portion 32 abuts on the front surface of the outer peripheral portion 15. The rib 33 is fixed at a position where it abuts on the front surface of the outer peripheral portion 15 and the upper surface of the bulging portion 16. In this position, the front plate portion 31 has a front surface substantially flush with the front surface of the bulging portion 16 and covers the upper recess 19 from the front, and the flat plate portion 32 covers the upper recess 19 from above. Therefore, the screws 37, 37 are hidden by the upper resin cover 30.

同様に、下凹部２０に対して、樹脂カバー３０を、平板部３２を下にして係止片３４，３４を被係止部２２，２２に差し込むようにして前方から組み付けると、凸部３５が被係止部２２を越えるまで係止片３４が差し込まれて弾性係止すると共に、平板部３２が外周部１５の前面に当接し、各補強リブ３３が外周部１５の前面及び膨出部１６の下面に当接する位置で固定される。この位置で前板部３１は、前面が膨出部１６の前面と略同一面上にあって下凹部２０を前方から覆い、平板部３２は下凹部２０を下方から覆う。よって、下側の樹脂カバー３０によってネジ３７，３７は隠されることになる。
一方、フロントカバー７を取り外す場合、まず、各樹脂カバー３０を、左右の表示部３６，３６を押して前板部３１を手前へ押し出すようにすれば、係止片３４，３４が被係止部２２，２２から抜き取られて上凹部１９及び下凹部２０から取り外すことができる。これにより外周部１５の上下でネジ３７，３７が露出するため、各ネジ３７を緩めて取り外せばフロントカバー７を筐体２から取り外すことができる。 Similarly, when the resin cover 30 is assembled to the lower recess 20 with the flat plate portion 32 down and the locking pieces 34, 34 inserted into the locked portions 22, 22, the convex portion 35 is The locking piece 34 is inserted until the locking portion 22 is exceeded and elastically locked, and the flat plate portion 32 abuts on the front surface of the outer peripheral portion 15, and each reinforcing rib 33 is a front surface of the outer peripheral portion 15 and the bulging portion 16 It is fixed in the position where it abuts on the lower surface of. In this position, the front plate portion 31 has a front surface substantially flush with the front surface of the bulging portion 16 and covers the lower recess 20 from the front, and the flat plate portion 32 covers the lower recess 20 from below. Therefore, the screws 37, 37 are hidden by the lower resin cover 30.
On the other hand, when the front cover 7 is removed, the locking pieces 34, 34 can be engaged by first pressing the left and right display portions 36, 36 to push the front plate portion 31 forward. 22 and 22 can be removed from the upper recess 19 and the lower recess 20. As a result, since the screws 37 are exposed at the upper and lower sides of the outer peripheral portion 15, the front cover 7 can be removed from the housing 2 by loosening and removing the respective screws 37.

このように、上記形態の給湯器１によれば、フロントカバー７に、筐体２へのネジ止め孔２１，２１を覆う樹脂カバー３０が着脱可能に装着されて、樹脂カバー３０は、ネジ止め孔２１，２１に隣接してフロントカバー７に切り起こし形成される被係止部２２，２２に、樹脂カバー３０の裏面に設けた係止片３４，３４を前方から弾性係止させることで装着されているので、フロントカバー７をネジ止めしても美観に優れるものとなる。また、弾性係止する樹脂カバー３０は前方から容易に着脱可能であるため、メンテナンス等の際にフロントカバー７を筐体２に着脱する手間も面倒にならない。   As described above, according to the water heater 1 of the above embodiment, the resin cover 30 covering the screwing holes 21 and 21 to the housing 2 is detachably attached to the front cover 7, and the resin cover 30 is screwed The locking pieces 34, 34 provided on the back surface of the resin cover 30 are resiliently locked from the front to the locked portions 22, 22 cut and raised in the front cover 7 adjacent to the holes 21, 21. Therefore, even if the front cover 7 is screwed, the appearance is excellent. Further, since the resin cover 30 to be resiliently locked can be easily attached and detached from the front, the time and effort of attaching and detaching the front cover 7 to the housing 2 at the time of maintenance or the like does not become troublesome.

特にここでは、フロントカバー７の背面に、被係止部２２の切り起こし形成によって生じる透孔２３を閉塞するシール板２４が貼着されているので、被係止部２２を切り起こし形成しても透孔２３から筐体２内への雨水等の浸入を防止することができる。
また、樹脂カバー３０に、フロントカバー７からの取り外しの際に係止片３４，３４の弾性係止を解除させるための操作位置を示す表示部３６，３６が設けられているので、樹脂カバー３０の取り外し作業が簡単に行える。 In particular, here, since the seal plate 24 is attached to the back surface of the front cover 7 for closing the through hole 23 generated by the cut and raised formation of the locked portion 22, the locked portion 22 is cut and raised. Also, it is possible to prevent the intrusion of rain water or the like into the housing 2 from the through holes 23.
Further, the resin cover 30 is provided with the display portions 36, 36 indicating the operating position for releasing the elastic locking of the locking pieces 34, 34 when the resin cover 30 is removed from the front cover 7. You can easily remove the

なお、樹脂カバーの位置や大きさ、形状は、上記形態に限らず、ネジ止め孔の位置や上下凹部の形状等に応じて適宜変更可能である。よって、係止片の位置や数も変更して差し支えない。
また、シール部材は上記形態のシール板に限らず、例えば透孔の部分のみを個別に閉塞する小面積のシール板とする等、少なくとも被係止部の切り起こし形成による透孔を閉塞可能であれば、適宜変更できる。表示部の位置や形状も変更可能である他、表示部の省略も可能である。 The position, size, and shape of the resin cover are not limited to those described above, and can be changed as appropriate depending on the position of the screw hole, the shape of the upper and lower recesses, and the like. Therefore, the position and the number of the locking pieces may be changed.
Further, the sealing member is not limited to the sealing plate of the above embodiment, and for example, it is possible to close the through hole by cutting and raising at least the engaged portion, such as a small area seal plate which individually closes only the through hole portion. If it is, it can change suitably. The position and shape of the display unit can be changed, and the display unit can be omitted.
