。As shown in Fig. 1, a conventional solar water heater system connects a heat collector 1 with a tank on the roof and a heat storage tank 2 on the ground through an outgoing pipe 3 and a returning pipe 4.
A circulation pump 5 was provided in the middle of the outgoing pipe 3. Further, the hot water supply pipe 6 was connected to the upper top plate portion 7 of the heat storage tank 2, and hot water was obtained by opening the hot water tap 8.

の悪いものであった。The disadvantage of this conventional method is that the return pipe 4 from the tank-equipped heat collector 1 is connected to the lower part of the heat storage tank 2, so the high temperature hot water that flows into the heat storage tank 2 from the return pipe 4 rises in the direction of arrow W. However, since the hot water is stored while being mixed with low-temperature hot water, that is, the hot water temperature is averaged as shown in graph A in Figure 3, the hot water taken out from the hot water supply pipe 6 is not always high temperature. When heat collection starts before the hot water reaches the set temperature, or when a large amount is used, only low-temperature hot water can be drawn, making it inconvenient to use.
本発明は上記従来の欠点を解消するもので、常時高温の

温の湯をとれることができ、使い勝手が非常によい。In order to achieve the above object, the solar water heater of the present invention has the following features:
a solar heat collector, a heat storage tank connected to the heat collector through an outgoing pipe and a return pipe, a circulation pump provided on the outgoing pipe, a hot water pipe connected to an upper part of the heat storage tank, and the heat storage tank. The outgoing pipe is connected to the lower part of the heat storage tank, the return pipe is connected to the upper part of the heat storage tank, and the amount of water circulating between the solar heat collector and the heat storage tank is controlled by the circulation pump. Approximately 0.2 to 0.62 per square meter of heat collection area
/ minute, it is possible to obtain hot water even immediately after the start of heat collection, and is very easy to use.

より取り出した給湯管である。In FIG. 2, 9 is a solar heat collector, 2 is a heat storage tank, which has a built-in pole tap 1o, and a water supply pipe 11 is connected to this pole tap 10. Reference numeral 12 denotes a partition wall for preventing mixing of hot water and water, and water is supplied to the heat storage tank 2 from the lower part. 3 is the outgoing pipe of the heat collecting circuit, and 4 is the returning pipe, each of which is connected to the solar heat collector 9.
and the heat storage tank 2, and the outgoing pipe 3 is connected to the lower part of the heat storage tank 2, and the return pipe 4 is connected to the upper part. Reference numeral 5 indicates a low temperature operation valve for the circulation pump installed in the outgoing pipe 3, which takes in air when the set temperature is reached. Reference numeral 6 denotes a hot water supply pipe taken out from the upper part of the return pipe 4 at the upper part of the heat storage tank 2.

次高温水が貯えられる。Water supplied into the heat storage tank 2 through the water supply pipe 11 by the pole tap 1o passes through the partition wall 12 and is supplied into the heat storage tank 2 from the bottom of the heat storage tank 2. In heat collection operation, low-temperature water at the bottom of the heat storage tank 2 is sucked in by the operation of the circulation pump 5, guided to the solar heat collector 9 through the outgoing pipe 3, heated by solar heat, and then passed through the return pipe 4 to the top of the heat storage tank 2. sent to. At this time, the circulation flow rate by the circulation pump 5 is 0.0.2 mm compared to the conventional general pump which is 1 u/rr1 inch or more per heat collection area.
Since the temperature is set as low as 2 to 0.6°C/min, the temperature difference at the entrance and exit of the collector can be increased to 10 to 20 deg, and the difference in density of water before and after the heat collection is also large, resulting in a high temperature in the upper part. The hot water will accumulate more easily. Further, since the outgoing pipe 3 and the returning pipe 4 of the heat collection circuit are connected to the lower and upper parts of the lid heat tank 2, respectively, high temperature water is stored sequentially from the upper part as the temperature inside the heat storage tank 2 changes.

てば使うことができる。Figure 2 shows the relationship between the elapsed heat collection time and the water temperature in the heat storage tank. The temperature change in the conventional example is shown. As is clear from this characteristic diagram,
In this embodiment, the temperature rises fastest at the upper 8 positions of the heat storage tank 2, followed by the middle position, and the lowest at the lower position C. Therefore, the temperature rises quickly in the upper part where the hot water supply pipe 6 is connected, and hot water can be used all the time or for a short time.
