The depth dimension L1 of the water heater is 800 mm, and the width dimension L2 is 685 mm. In addition, although the height dimension L4 of a housing | casing is 1972 mm, the height dimension L3 of a water heater is 2132 mm because the housing support leg 11 whose height dimension L5 is 160 mm is attached to the housing.
また、この電気給湯機は、筐体の前面の高さ方向下部を奥行き方向後方に後退させて、配管を接続するための配管接続空間（即ち、けこみ）Ｓが形成されている。筐体は、天面部１と、底面部２と、前面部３と、背面部５と、一対の側面部６，７とを備えるとともに、配管接続空間Ｓを形成すべく後退した位置に配置される後退面部８と、配管接続空間Ｓの上面となる空間上面部９とを備えて構成され、後退面部８と空間上面部９とは、配管接続空間Ｓを画成する配管接続部材４として一体的に設けられ、一対の側面部６，７のうちの少なくとも一方は、配管接続空間Ｓに対応して前方側下部を切り欠かれた構造となっている。即ち、けこみと形状を一致させるように、側面部６，７の一部は切り欠かれて凹部が形成されている。 In addition, this electric water heater is provided with a pipe connection space (that is, a dent) S for connecting pipes by retreating the lower part in the height direction of the front surface of the housing backward in the depth direction. The housing includes a top surface portion 1, a bottom surface portion 2, a front surface portion 3, a back surface portion 5, and a pair of side surface portions 6 and 7, and is disposed at a position retracted to form a pipe connection space S. The receding surface portion 8 and the space upper surface portion 9 serving as the upper surface of the pipe connection space S are configured, and the receding surface portion 8 and the space upper surface portion 9 are integrated as a pipe connection member 4 that defines the pipe connection space S. At least one of the pair of side surface parts 6 and 7 has a structure in which the lower part on the front side is cut out corresponding to the pipe connection space S. That is, a part of the side surface parts 6 and 7 is notched so as to form a recess so as to match the shape with the depression.
ここで、配管接続部材４は、筐体１０の前面側下方に配置される。また、配管接続部材４の空間上面部９は、給水管と給湯管を筐体１０外部の水道管や給湯利用端末へと導く配管と接続するための継手を固定する略水平な部位であり、後退面部８は、空間上面部９と直交する略垂直な部位である。 Here, the pipe connection member 4 is disposed below the front side of the housing 10. Moreover, the space upper surface part 9 of the pipe connecting member 4 is a substantially horizontal part that fixes a joint for connecting a water supply pipe and a hot water supply pipe to a pipe leading to a water pipe or a hot water supply terminal outside the housing 10, The receding surface portion 8 is a substantially vertical portion orthogonal to the space upper surface portion 9.
空間上面部９は、現地据付作業性を良好なものとするため、接地面からの高さＬ９は約５２０mmに設定され、後退面部８は、前面部３の表面から背面部５がある奥行き方向へ向かって距離Ｌ１１約９２mm後退した位置に配置される。なお、寸法関係に関しては後述する。 The space upper surface portion 9 is set to have a height L9 of about 520 mm from the ground surface in order to improve the field installation workability, and the receding surface portion 8 extends from the surface of the front surface portion 3 to the depth direction where the rear surface portion 5 is located. The distance L11 is set at a position retracted by about 92 mm. The dimensional relationship will be described later.
図２及び図３に示すように、タンク１３は、タンク支持脚１４によって支持されている。タンク支持脚１４は、３つ設けられており、タンク支持脚１４の少なくとも一つは筐体の前面側に配置されている。具体的には、前面側のタンク支持脚１４は、図２に示すように、前面の幅方向中央部に配置されている。また、他のタンク支持脚１４は、図３に示すように、筐体の背面側に配置されており、背面側の２つのタンク支持脚１４は、幅方向中央部を挟んでその両側に配置されている。 As shown in FIGS. 2 and 3, the tank 13 is supported by a tank support leg 14. Three tank support legs 14 are provided, and at least one of the tank support legs 14 is disposed on the front side of the housing. Specifically, as shown in FIG. 2, the tank support leg 14 on the front side is disposed at the center in the width direction of the front side. Further, as shown in FIG. 3, the other tank support legs 14 are arranged on the back side of the casing, and the two tank support legs 14 on the back side are arranged on both sides of the widthwise center portion. Has been.
タンク１３と前面側のタンク支持脚１４との接合部１５は、空間上面部９に対応する高さ位置に設けられている。従って、図２や図５に示すように、前面側から見ると、接合部１５は、空間上面部９と高さ方向に重複する配置となる。なお、図３や図６にはタンク支持脚１４や接合部１５が表れていないが、側面側から見ると、空間上面部９の奥行き方向後方に位置する配置となっている。 The joint portion 15 between the tank 13 and the tank support leg 14 on the front side is provided at a height position corresponding to the space upper surface portion 9. Therefore, as shown in FIG. 2 and FIG. 5, when viewed from the front side, the joint portion 15 is disposed so as to overlap the space upper surface portion 9 in the height direction. 3 and 6 do not show the tank support leg 14 or the joint 15, but when viewed from the side, the tank support leg 14 and the joint 15 are located behind the space upper surface 9 in the depth direction.
図５，図６に基づき、各部の寸法について説明すると、タンク支持脚１４の高さ寸法Ｌ６は３９３mmであり、高さ寸法Ｌ５が１６０mmの筐体支持脚１１と合わせると、接地面からの高さＬ７は５５３mmとなる。また、タンク１３と前面側のタンク支持脚１４とは、所定長さＬ１０に亘って接合されており、具体的には、接合部１５の長さＬ１０は９０〜１１０mmに設定される。また、空間上面部９は、筐体の下端からの高さＬ８は３６０であるが、高さ寸法Ｌ５が１６０mmの筐体支持脚１１と合わせると、接地面からの高さＬ９は、５２０mmとなる。 The dimensions of each part will be described with reference to FIGS. 5 and 6. The height L6 of the tank support leg 14 is 393 mm, and when the height L5 is combined with the case support leg 11 having a height L160 of 160 mm, The length L7 is 553 mm. The tank 13 and the tank support leg 14 on the front side are joined over a predetermined length L10. Specifically, the length L10 of the joined portion 15 is set to 90 to 110 mm. The space upper surface portion 9 has a height L8 from the lower end of the housing of 360, but when combined with the housing support leg 11 having a height L5 of 160 mm, the height L9 from the ground contact surface is 520 mm. Become.
上記構成によれば、タンクの前面側に配置される機能部品の配置の自由度を向上させることができる。即ち、空間上面部に対応する高さ位置は、機能部品の取り付けやメンテナンスの作業性を考慮すると、その高さ位置に機能部品を配置しにくい部分である。また、接合部は、機能部品を配置することができない部分である。この点、本実施形態のようにタンクと支持脚との接合部を空間上面部に対応する高さ位置に設けることで、機能部品を配置する上で制約となる部分を集約することができ、タンクの前面側に配置される機能部品の配置の自由度を向上させることができる。 According to the said structure, the freedom degree of arrangement | positioning of the functional component arrange | positioned at the front side of a tank can be improved. That is, the height position corresponding to the upper surface portion of the space is a portion where it is difficult to place the functional component at the height position in consideration of workability of mounting and maintenance of the functional component. Moreover, a junction part is a part which cannot arrange | position a functional component. In this respect, by providing the joint portion between the tank and the support leg at a height position corresponding to the upper surface portion of the space as in the present embodiment, it is possible to aggregate the parts that are constrained when placing the functional components, The freedom degree of arrangement | positioning of the functional component arrange | positioned at the front side of a tank can be improved.
例えば、下から二番目に設けられるサーミスタ取付部１６は、接合部や空間上面部に近い位置に設けられるものであるが、接合部と空間上面部とを集約することで、このサーミスタ取付部１６を設けることが可能な範囲を大きくすることができ、延いてはこの位置に取り付けられるサーミスタの配置の自由度が向上している。また、サーミスタの配置自由度が向上すると、それに伴って配管の取り回しの自由度も向上させることができるといったように、機能部品同士の配置の自由度も向上させることができる。 For example, the thermistor mounting portion 16 that is provided second from the bottom is provided at a position close to the joint portion or the space upper surface portion, but the thermistor mounting portion 16 is integrated by consolidating the joint portion and the space upper surface portion. Thus, the range in which the thermistor can be provided can be increased, and the thermistor attached to this position is more freely arranged. Further, when the thermistor arrangement degree of freedom is improved, the degree of freedom of arrangement of the functional parts can be improved, such that the degree of freedom of the piping can be improved accordingly.
