Description
本発明は、給湯器に関し、特に給湯器を外部の支持部材に取付ける為の給湯器取付部材を給湯器ケースに容易かつ能率的に組付け可能にしたものに関する。 The present invention relates to a water heater, and more particularly to a water heater attachment member for attaching a water heater to an external support member that can be easily and efficiently assembled to a water heater case.
給湯器をパイプシャフト等に開口する開口部に設けた矩形状枠部材等に取付ける構造として、通常、給湯器のケースの外周側壁面の前端近傍部に枠状の給湯器取付部材を固定し、その給湯器取付部材を矩形状枠部材等に複数のビスやボルトにより固定する構造が採用されている。 As a structure for attaching a water heater to a rectangular frame member or the like provided in an opening that opens to a pipe shaft or the like, a frame-shaped water heater attachment member is usually fixed to the vicinity of the front end of the outer peripheral side wall surface of the case of the water heater, A structure is employed in which the water heater attachment member is fixed to a rectangular frame member or the like with a plurality of screws or bolts.
例えば、特許文献１に記載のガス給湯機の取付け構造においては、パイプシャフトに開口する開口部に本体固定用金枠が固定され、給湯器のケースの外周側壁面の前端近傍部に枠状の固定枠取付フランジが溶接等で取付けられ、給湯器を本体固定用金枠に挿入後、固定枠取付フランジを本体固定用金枠に複数のビスで固定している。尚、ケースの前端部には、サービスカバー取付用フランジが形成され、このサービスカバー取付用フランジにサービスカバーが複数のビスで固定される。 For example, in the gas water heater mounting structure described in Patent Document 1, a main body fixing metal frame is fixed to an opening opening in a pipe shaft, and a frame-like shape is formed in the vicinity of the front end of the outer peripheral side wall surface of the case of the water heater. The fixed frame mounting flange is mounted by welding or the like, and after inserting the water heater into the main body fixing metal frame, the fixed frame mounting flange is fixed to the main body fixing metal frame with a plurality of screws. A service cover mounting flange is formed at the front end of the case, and the service cover is fixed to the service cover mounting flange with a plurality of screws.
従来、前記ケースはメッキ鋼板等で製作され、給湯器取付部材はケースの外周側壁面の前端近傍部にスポット溶接等で接合され、その溶接後にケース及び給湯器取付部材に塗装を施していた。この構造では、ケースと給湯器取付部材の間に殆ど隙間が発生しないため、雨水が給湯器の内部へ侵入しにくくなっていた。尚、給湯器取付部材は、ケースの４面に対応する４部材で枠状に形成される。 Conventionally, the case is made of a plated steel plate, the water heater attachment member is joined to the vicinity of the front end of the outer peripheral side wall surface of the case by spot welding or the like, and the case and the water heater attachment member are painted after the welding. In this structure, since almost no gap is generated between the case and the water heater attachment member, it is difficult for rainwater to enter the water heater. The water heater attachment member is formed in a frame shape with four members corresponding to the four surfaces of the case.
特許文献１のガス給湯機の取付け構造においては、給湯器のケースに枠状の固定枠取付フランジが溶接等で取付ける構造であるため、ケースをカラー鋼板で製作できないという問題がある。
最近、ケースをカラー鋼板で製作するようになると、前記ケースに給湯器取付部材を構成する４部材をスポット溶接ではなく、複数のビスで固定することになる。この場合、給湯器の組み立てライン上に９０°回転させて寝かせた状態のケースの４つの壁面に給湯器取付部材の４部材をビスにて取付ける。この場合、作業者側から視て手前側と反対側（反手前側）のビス穴は作業者が目視できない位置にあるため、手さぐり状態でビス固定することになる。
The mounting structure of the gas water heater in Patent Document 1 has a problem that the case cannot be manufactured from a color steel plate because the frame-shaped fixed frame mounting flange is mounted on the case of the water heater by welding or the like.
Recently, when a case is made of a color steel plate, the four members constituting the water heater mounting member are fixed to the case with a plurality of screws instead of spot welding. In this case, four members of the water heater attachment member are attached with screws to the four wall surfaces of the case that is rotated and rotated by 90 ° on the assembly line of the water heater. In this case, the screw hole on the side opposite to the front side (opposite side) as viewed from the operator side is in a position where the operator cannot visually check, so the screw is fixed in a hand-off state.
そこで、反手前側ではビス固定部位を最小限にし、その他の部位はビス固定に代えて係合部を係止部に係合させる連結構造にしたいという要請がある。しかも、係合部を係合させる際に、目視することなく能率的に確実に係合させ得る構造が特に望ましい。 Therefore, there is a demand for a connecting structure in which the screw fixing portion is minimized on the front side, and the other portion is engaged with the engaging portion instead of screw fixing. In addition, a structure that can be engaged efficiently and reliably without visual inspection when engaging the engaging portion is particularly desirable.

The second cutout portion 31 is formed in an elongated trapezoidal shape at the front end side portion of the contact plate portion 22a corresponding to the stepped portion 11b of the flange portion 11 when the engaging portion 28 approaches the locking portion 27. Yes.
図７に示すように、第２部材２２をフランジ部１１とガイド部２６間の隙間Ｇからガイド部２６の内側へ導入可能にするため、フランジ部１１とガイド部２６間の隙間Ｇは、鍔板部２２ｄの幅よりも大きく設定されている。 As shown in FIG. 7, in order to allow the second member 22 to be introduced into the guide portion 26 from the gap G between the flange portion 11 and the guide portion 26, the gap G between the flange portion 11 and the guide portion 26 is It is set larger than the width of the plate portion 22d.
以上説明した給湯器１の作用、効果について説明する。
給湯器１を組み立てる際には、組立ライン上にケース４を前面側を上方に向けた仰向け姿勢に寝せた状態で、ケース４内に機器類を取付けつつ、ケース４の前端近傍部の外面側に給湯器取付部材５を取付けていく。
給湯器取付部材５の取付けの際、最初に、第１部材２１を４つのビス２５で上面板８に固定すると共に、第４部材２３を２つのビス３２で底面板１１に固定する。
The operation and effect of the water heater 1 described above will be described.
When assembling the water heater 1, the case 4 is laid on the assembly line in a supine posture with the front side facing upward, and the outer surface of the vicinity of the front end of the case 4 is attached to the case 4. The water heater attachment member 5 is attached to the side.
When attaching the water heater attachment member 5, first, the first member 21 is fixed to the top plate 8 with the four screws 25, and the fourth member 23 is fixed to the bottom plate 11 with the two screws 32.
次に、図７に示すように、第２部材２２を約３０°〜４５°ほど右側板１０に対して傾斜姿勢にした状態で、第２部材２２を後方（背面板７側）へ移動させ、第２部材２２の上部をフランジ部１１とガイド部２６の間の隙間Ｇからガイド部２６の内側へ導入し、係合板部２２ｂを上面板８に対向させて第２部材２２を下方（底面板１１側）へ移動させつつ、当接板部２２ａが右側板１０に接近するように上面板８と右側板１０に直交する水平平面内で回動させ、係合板部２２ｂを上面板８に当接させると、係止部２７が第１の切欠部２９に導入され、当接板部２２ａが右側板１０に当接状態となり、係合部２８が係止部２７に係合状態となり、下側係合板部２２ｃが底面板１１に当接する。尚、上側の係合板部２２ｂのビス穴は使用しない。 Next, as shown in FIG. 7, the second member 22 is moved backward (back plate 7 side) in a state where the second member 22 is inclined with respect to the right side plate 10 by about 30 ° to 45 °. The upper part of the second member 22 is introduced into the guide part 26 through the gap G between the flange part 11 and the guide part 26, and the second member 22 is moved downward (bottom) with the engaging plate part 22b facing the upper surface plate 8. The upper surface plate 8 and the right side plate 10 are rotated in a horizontal plane perpendicular to the upper surface plate 8 and the right side plate 10 so that the abutting plate portion 22a approaches the right side plate 10 while moving to the upper surface plate 8. When brought into contact, the locking portion 27 is introduced into the first cutout portion 29, the contact plate portion 22a is in contact with the right side plate 10, and the engaging portion 28 is in engagement with the locking portion 27. The lower engagement plate portion 22 c comes into contact with the bottom plate 11. Note that the screw hole of the upper engagement plate portion 22b is not used.
その状態で、下側係合板部２２ｃのビス穴３０にビス３３をネジ込んで、下側係合板部２２ｃを底面板１１に固定すると、第２部材２２の取付けが完了する。尚、左側の第２部材も上記と同様にして左側板９と上面板８と底面板１１に取付ける。 In this state, when the screw 33 is screwed into the screw hole 30 of the lower engagement plate portion 22c and the lower engagement plate portion 22c is fixed to the bottom plate 11, the attachment of the second member 22 is completed. The second member on the left side is also attached to the left side plate 9, the top plate 8, and the bottom plate 11 in the same manner as described above.
このように、第１部材２１の取付け後に第２部材２２を上面板８及び右側板１０と直交する平面内で回動させつつ係合部２８を係止部２７に係合させる際に、ガイド部２６で第２部材２２をガイドしながら、目視することなく係合部２８を係止部２７に係合させることができるから、第２部材２２の取付けを容易に能率的に行うことができる。
また、係合部２８を係止部２７に係合させる構造としたので、ビス止めが不要となり、目視しにくい部位でのビス止めの作業を省略することができる。
As described above, when the second member 22 is rotated in a plane orthogonal to the upper surface plate 8 and the right side plate 10 after the first member 21 is attached, Since the engaging part 28 can be engaged with the engaging part 27 without visually observing the second member 22 while guiding the second member 22 with the part 26, the second member 22 can be easily and efficiently attached. .
Further, since the engaging portion 28 is engaged with the locking portion 27, screwing is unnecessary, and the screwing operation at a site that is difficult to see can be omitted.
第２部材２２の当接板部２２ａには、第２部材２２を回動させつつ係合部２８を係止部２７に係合させる際にフランジ部１１の段差部１１ｂを通過させる第２の切欠部３１を形成したので、当接板部２２ａがフランジ部１１の段差部１１ｂと緩衝することなく円滑に回動可能である。 The contact plate 22a of the second member 22 is a second plate through which the step portion 11b of the flange portion 11 passes when the engaging portion 28 is engaged with the locking portion 27 while the second member 22 is rotated. Since the notch portion 31 is formed, the contact plate portion 22a can be smoothly rotated without buffering with the step portion 11b of the flange portion 11.
ケース２のフランジ部１１とガイド部２６間の隙間Ｇは鍔板部２２ｄの幅よりも大きく設定してあるため、第２部材２２を上記の隙間Ｇからガイド部２６の内側へ導入してガイド部２６でガイドしながら回動させることができる。 Since the gap G between the flange portion 11 and the guide portion 26 of the case 2 is set to be larger than the width of the flange portion 22d, the second member 22 is introduced into the guide portion 26 from the gap G and guided. It can be rotated while being guided by the portion 26.
