通常、貯湯給湯装置は屋外に設置されることが多いため、外装ケースによって内部の機器類に雨水がかからないように保護されている。外装ケースは、柱部材や桟部材からなる複数のフレーム部材を組み合わせて構成されたほぼ直方体形状のケース本体の天面及び４つの側面部に夫々外板部材を固定して形成されている。
It is provided with a hot water storage tank for storing hot water, a combustion type auxiliary heat source machine that heats the hot water in the hot water storage tank when the temperature is low, and an exterior case containing equipment such as the hot water storage tank and the auxiliary heat source machine. Hot water storage and hot water supply devices are widely used in practical use.
Since the hot water storage and hot water supply device is usually installed outdoors, the outer case protects the internal equipment from rainwater. The outer case is formed by fixing outer plate members to the top surface and four side surface portions of a case body having a substantially rectangular parallelepiped shape, which is formed by combining a plurality of frame members composed of pillar members and crosspiece members.
特許文献１に記載の屋外設置型温水装置の外装ケースにおいては、下側扉の上端部分にケース内方へ板厚分だけ段押しした段差が形成され、上側扉の下端部分を下側扉の上端部分（段押し部分）に密着状に外嵌させる構造が採用されている。上側扉の下端部分の裏面に密着裏面が形成され、
下側扉の上端部分（段押し部分）の表面に密着表面が形成され、前記密着裏面を段押し部分の

In the outer case of the outdoor installation type water heating device described in Patent Document 1, a step is formed in the upper end portion of the lower door by stepping inward by the plate thickness, and the lower end portion of the upper door is the lower door. A structure is adopted in which the upper end portion (step push portion) is fitted so tightly. A close contact back surface is formed on the back surface of the lower end of the upper door.
A close contact surface is formed on the surface of the upper end portion (step push portion) of the lower door, and the close contact back surface is tightly wrapped with the close contact surface of the step push portion to seal the connection portion between the upper door and the lower door. ing. The upper door and the lower door are fixed to the case body with a plurality of screws.
特許文献１の外装ケースでは、上側扉と下側扉は複数のビスにてケース本体に固定されるため、上側扉の表面と下側扉の表面とを容易に同一の鉛直面に一致させることができる。
しかし、このように外板部材を複数のビスで固定すると、複数のビスが外装ケースの表面に現われるため貯湯給湯装置の外観が悪化する。

However, when the outer panel member is fixed with a plurality of screws in this way, the plurality of screws appear on the surface of the outer case, and the appearance of the hot water storage device deteriorates.
そこで、外板部材をビスを用いずにケース本体に固定することが望ましい。そのため、本願出願人が採用している外装ケースでは、前面の上下２枚の外板部材の接続部を次のように形成している。即ち、上側外板部材の下端部をケース内方へ直角に折り曲げて剛性を高めたフランジ部を形成し、下側外板部材の上端部分には、ケース内方へ断面クランク状に段押しして剛性を高めたクランク部を形成し、前記フランジ部とその上側近傍部分をクランク部に外側からラップさせ、フランジ部をクランク部の段部に当接又は近接させている。 Therefore, it is desirable to fix the outer plate member to the case body without using screws. Therefore, in the exterior case adopted by the applicant of the present application, the connecting portions of the two upper and lower outer panel members on the front surface are formed as follows. That is, the lower end of the upper outer plate member is bent inward at a right angle to form a flange portion with increased rigidity, and the upper end portion of the lower outer plate member is stepped inward in the case in a cross-sectional crank shape. A crank portion having increased rigidity is formed, the flange portion and a portion near the upper side thereof are wrapped around the crank portion from the outside, and the flange portion is brought into contact with or close to the step portion of the crank portion.
ここで、最近では、外装ケースの製作費と重量軽減のため外板部材の薄板化が進められているため、外板部材に歪みが発生し易くなっている。しかし、前記の接続部では、フランジ部とクランク部を何ら係合させていないため、外板部材の接続部近傍部分の外表面の連続性を確保することが困難になっている。
本発明の目的は、外板部材の端部同士を係合構造を介して接続するようにした外装ケースを有する貯湯給湯装置を提供することである。

The vertical wall portion 17b is formed larger than the depth of the shaped portion 15, and is inclined with respect to the vertical surface so as to move downward toward the rear, and plunges into the opening 5d formed in the recessed portion 5c.
後壁部１６ａと上壁部１７ａと縦壁部１７ｂは台形状に形成され、第２コ字状部１７が第１コ字状部１５に上方から係合されて、第１コ字状部１５の上端が第２コ字状部１７の後側の角部の内面に当接している。
こうして、第２コ字状部１７が前後方向に変位しないように第１コ字状部１５により位置規制されているため、第１，第２コ字状部１５，１７が形成される下側外板９と上側外板１０の外表面は同一鉛直面を形成している。
The rear wall portion 16a, the upper wall portion 17a, and the vertical wall portion 17b are formed in a trapezoidal shape, and the second U-shaped portion 17 is engaged with the first U-shaped portion 15 from above to form the first U-shaped portion. The upper end of 15 is in contact with the inner surface of the rear corner of the second U-shaped portion 17.
In this way, since the position of the second U-shaped portion 17 is restricted by the first U-shaped portion 15 so as not to be displaced in the front-rear direction, the lower side where the first and second U-shaped portions 15 and 17 are formed. The outer surfaces of the outer plate 9 and the upper outer plate 10 form the same vertical plane.
尚、折返部１６と第２コ字状部１７の上記の形状は一例を示すものに過ぎず、後壁部１６ａや縦壁部１７ｂが鉛直方向に向くように形成してもよい。 The above-mentioned shapes of the folded-back portion 16 and the second U-shaped portion 17 are merely examples, and the rear wall portion 16a and the vertical wall portion 17b may be formed so as to face in the vertical direction.
以上説明した貯湯給湯装置１の作用、効果、特に外装ケース４の作用、効果について説明する。下側外板９と上側外板１０に所定間隔おきに複数のビード１１が形成されているため、下側外板９と上側外板１０の剛性が高まって歪みにくくなり、平面性を確保するのに有利である。 The actions and effects of the hot water storage and hot water supply device 1 described above, particularly the actions and effects of the exterior case 4, will be described. Since a plurality of beads 11 are formed on the lower outer plate 9 and the upper outer plate 10 at predetermined intervals, the rigidity of the lower outer plate 9 and the upper outer plate 10 is increased to prevent distortion and ensure flatness.
