器２２がその下方に収納されている。 An embodiment of this invention is shown in FIGS. 3 to 6. In the figure, reference numeral 7 denotes a drum-shaped hot water storage tank that is erected on pillars 9, and has a jacket type heat exchanger 8 on the outer periphery of the lower part. A hot water supply pipe 10 is connected to the top of the hot water storage tank 7, and a water supply pipe 11 and a drain pipe 12 are connected to the bottom thereof. The hot water storage tank 7 is covered with a main exterior cover 14 via a heat insulating material 13.
A circulation pump 15 is installed inside the main exterior cover 14 below. The heat insulating material 13 is made of glass wool or the like, and its surface is coated with nylon. The circulation pump 15 has its suction port connected to the jacket heat exchanger 8 via piping 18, and its discharge port connected to an external solar heat sink (not shown) through piping. The outlet of the solar heat sink is piped to a jacket heat exchanger. An inspection port 19 for the circulation pump 15 is provided at the lower front end of the main exterior cover 14 . In addition, a box-shaped decorative cover 20 with an open rear surface is provided on the front surface of the main exterior cover 14 over substantially the entire height, and an expansion tank 21 is housed in the upper part and a controller 22 is housed in the lower part.

２７には溝状凹部２６内に配置されたオーバーフ
ローホース２８（第３図）が接続される。 The tank body 21a of the expansion tank 21 has a rear surface formed into an uneven arcuate surface along the outer surface of the main exterior cover 14, and is attached to the main exterior cover 14. A heat medium inlet 23 is provided on the top surface of the tank body 21a, and a heat medium circulation port 24 is provided on the bottom surface.
The circulation port 24 is connected to the upper end of the jacket type heat exchanger 8 via a pipe 25 (FIG. 3). A groove-shaped recess 26 reaching from the lower end to near the upper end is provided at the corner of one side edge of the front surface of the tank body 21a, and a downward overflow port 2 is provided at the upper end surface of the groove-shaped recess 26.
7 is formed into a short tube shape. An overflow hose 28 (FIG. 3) disposed within the groove-shaped recess 26 is connected to the overflow port 27.
このように、タンク本体２１ａの外側面に溝状
凹部２６を設け、その上端面にオーバーフロー口
２７を設けたため、従来のようにオーバーフロー

小さくなり、美観も向上する。 In this way, the groove-like recess 26 is provided on the outer surface of the tank body 21a, and the overflow port 27 is provided on the upper end surface of the tank body 21a, so that the tank body 21a fits inside the decorative cover 20 without any gaps, unlike the conventional structure in which the overflow port protrudes. . Therefore, the decorative cover 20 becomes smaller and its aesthetic appearance is improved.
この考案の膨張タンクは、化粧カバーへの納ま
りが良く、小さなスペースに収納できて、美観の
向上も図ることができるという効果がある。
The expansion tank of this invention fits well into the decorative cover, can be stored in a small space, and has the advantage of improving aesthetics.
