た後に給湯するようにしている。 As shown in Fig. 1, in a natural circulation type solar water heater in which the hot water storage tank 11 is installed above the heat collector 12, high-temperature water reaches 60°C in the summer.
To prevent burns, etc., high-temperature water is not directly supplied, but rather is mixed with low-temperature city water, or tap water, to lower the temperature to a certain level before supplying hot water.

であつてもよい。 FIG. 2 shows a conventional solar water heater constructed with this point in mind. Water is heated in the collector 12 by a cistern 14 and a constant temperature mixing valve 15, which are provided separately from the cistern 13 that supplies water to the hot water storage tank 11. Tap water is mixed with the high-temperature water that has become smaller and flowed into the hot water storage tank 11, and the temperature is maintained at approximately 45°C to supply hot water. In addition, the arrow in FIG. 1 shows the flow direction of water, and 16 in FIG. 1 and FIG. 2 may be a heat pipe.

る。 FIG. 3 shows a first embodiment of the invention,
In the figure, 1 is a hot water storage tank, 2 is a collector, 3 is a water circulation path in the collector 2, and the hot water tank 1 is a collector 2.
It is installed above the roof, creating a natural circulation pattern. A cistern 4 for water supply is provided adjacent to the hot water storage tank 1, and tap water is supplied to this cistern 4. The bottom of the cistern 4 and the bottom of the hot water storage tank 1 are connected by a pipe 5 and a trap 6, and the height near the bottom of the trap 6 is below the bottom of the hot water storage tank 1 as shown in FIG. In other words, there is a relationship of h 1 ≧ h 2 . A pipe 7 extends from near the bottom of the trap 6, and together with a pipe 8 extending from the top of the hot water tank 1, a constant temperature mixing valve 9 is connected.
The temperature-controlled hot water is supplied from a pipe 10 on the output side of the constant-temperature mixing valve 9.

The water in the pipe 5 and the cistern 4 can be kept at a low temperature, and the cold water is passed through the pipe 7 to the constant temperature mixing valve 9.
The hot water can be mixed with high-temperature water from pipe 8 and supplied from pipe 10.

の底面以下（h3≧h4）に設定されている。 FIG. 4 shows a second embodiment. In this example, a trap 6' is provided at the bottom of the hot water storage tank 1, and a heat-insulated pipe 5' is provided so that the lower end opening is located within the trap 6'. The upper end opening of the pipe 5' is communicated with the bottom of the cistern 4, and the pipe 7 is communicated with the cistern 4 leading to the constant temperature mixing valve 9. The other structures are the same as those in the first embodiment, so detailed description will be omitted. Furthermore, as shown in Fig. 4B, the height of the lower end opening of the pipe 5' is equal to the height of the hot water tank 1.
(h 3 ≧ h 4 ).

ことができる。 In this embodiment, the water in the trap 6' is at a low temperature during heat collection, and the water in the cistern 4 is also kept at a low temperature via the insulated pipe 5'.
Cold water can be supplied to the constant temperature mixing valve 9 in the same way as in the embodiment.

る。 FIG. 5 shows a third embodiment. In this example, a weir 4' is provided in the cistern 4 to divide the cistern 4 into a high temperature section 4a and a low temperature section 4b. This leads to the mixing valve 9. Regarding other configurations, the same components as those in the first and second embodiments are given the same reference numerals, and the description thereof will be omitted.

がパイプ１０より給湯されるものである。 In this embodiment, water supply to the cistern 4 is controlled by the water level of the high temperature section 4a, and water overflowing from the high temperature section 4a is supplied to the constant temperature mixing valve 9 via the low temperature section 4b and the pipe 7. During heat collection, high-temperature water accumulates in the upper part of the hot water tank 1 and the high temperature part 4a of the cistern 4, and the constant temperature mixing valve 9 collects high temperature water in the hot water tank 1.
High-temperature water is supplied from a pipe 8 provided at the upper part of the cistern 4, and cold water is supplied from a low-temperature section 4b of the cistern 4 via a pipe 7, and these are mixed and hot water at an appropriate temperature is supplied from a pipe 10.

上面の水の密度の方が貯湯槽の底の水の密度より

の温度は貯湯槽中の水の温度（水の温度と密度は
相関関係がある）より低くするためである。 Note that a trap 6 is installed between the pipe 5 and the hot water tank 1.
The provision of the trap 6 is necessary for supplying water from the sheath tank 4 to the hot water storage tank, and if the trap 6 is not provided, water will not be supplied to the hot water storage tank 1. Also, the reason why the height of the bottom of the hot water storage tank was made to be at least greater than the height of the lower opening of the flow channel communicating with the cistern is that, for example, h 1 in Figures 3 and 4 (b)
h 2 means that when comparing the density of water in the trap and the density of water at the bottom of hot water storage tank 1, the density of water at the top of the trap is higher than the density of water at the bottom of the hot water storage tank. This is to make the temperature of the water in the trap lower than the temperature of the water in the hot water storage tank (there is a correlation between water temperature and density).

図れる利点を有する。 As described above, according to the present invention, all or part of the water in the cistern leading city water such as tap water to the hot water storage tank is kept at a low temperature, and the high temperature water supplied from the upper part of the hot water storage tank and the water in the cistern are kept at a low temperature. Since hot water is supplied by mixing cold water with a constant temperature mixing valve and a cistern is attached to the hot water storage tank, one cistern can perform a constant temperature mixing function compared to the conventional example, and the temperature of hot water can be adjusted. It has the advantage of being able to maintain the temperature at an appropriate temperature, as well as reducing the size and cost of the device due to the reduction in the number of parts.
