However, since this conventional solar water heater uses solar cells as a power source to drive the circulation pump, the voltage applied to the circulation pump gradually changes from a low voltage as the amount of solar radiation increases. As a result, air locks (a phenomenon in which air accumulates and obstructs the flow of the heat medium) are likely to occur within the circulation pump, and once an air lock occurs, it is difficult to recover.
Therefore, in this conventional solar water heater,
There was a risk that a predetermined head of the circulation pump could not be secured, leading to a situation in which heat collection operation could not be performed.
本考案は、上記問題点に鑑み案出されたもので

According to the solar water heater of the present invention, a thin tube is provided that connects the open water surface upper part of the outgoing pipe and the hot water storage tank, so the loop of hot water tank → inside the circulation pump → outgoing pipe → narrow tube → hot water storage tank is used when low voltage is applied. This allows the heat medium to circulate more easily, and even if an air lock occurs, it can be easily recovered.
以下、本考案を添付図面に基づき詳細に説明す

で棟４ａの両側に振り分けて設置されている。 The heat collector 1 and the hot water storage tank 2 have arms 3a and 3b.
They are connected to each other via a ridge 4a of the roof 4, and are distributed and installed on both sides of the ridge 4a.

前記往き管５ａの貯湯槽２近傍で往き管５ａの
開放水面より下部には、熱媒（水）を循環させる
ための循環ポンプ６が設けられている。 A circulation pump 6 for circulating a heat medium (water) is provided near the hot water storage tank 2 of the outgoing pipe 5a and below the open water surface of the outgoing pipe 5a.
また、アーム３ａには太陽電池１７が取付けら

媒が循環し、集熱運転されることとなる。 Further, a solar cell 17 is attached to the arm 3a, and by driving the circulation pump 6 with the electromotive force of this solar cell 17, the hot water tank 2 → the outgoing pipe 5
The heat medium circulates in the order of a → heat collector 1 → return pipe 5b → hot water storage tank 2, and heat collection operation is performed.
本考案においては、往き管の開放水面より上部

ことが重要である。 In the present invention, it is important to provide a thin tube connecting the outgoing pipe and the hot water storage tank above the open water surface of the outgoing pipe.
このため、第２図に示す実施例では、往き管５

せることができる。 Therefore, in the embodiment shown in FIG.
The hot water storage tank 2 is connected to the upper part of the open water surface X in a by a thin tube 7. In this way, by connecting the outgoing pipe 5a and the hot water storage tank 2 with the thin tube 7, even if the heat medium (water) does not circulate between the heat collector 1 and the hot water storage tank 2, the circulation pump 6 → the outgoing pipe A heat medium (water) is circulated in a loop of 5a→thin tube 7→hot water tank 2→circulation pump 6, and the air inside the circulation pump 6 can be expelled by the circulation of this heat medium. Therefore, the circulation pump 6
Even if an airlock occurs inside, it can be easily recovered.
尚、細管７は、往き管５ａよりもはるかに小径
に形成されていることから、通常の集熱運転中は
集熱回路に比べて細管７の圧力損失が大きいため
水が細管７にシヨートパスする量も全体の循環量
にくらべてわずかであり、集熱には影響ない。 In addition, since the thin tube 7 is formed to have a much smaller diameter than the outgoing tube 5a, during normal heat collection operation, the pressure loss in the thin tube 7 is larger than that in the heat collecting circuit, so water passes through the thin tube 7 by shortcut. The amount is also small compared to the total circulation amount and does not affect heat collection.
