る。 At a position above the heat collector 2 between the solenoid valve 20 and the heat collector 2, a solenoid valve 27 is disposed as a valve body that opens the circuit to the atmosphere and drains water from the heat collector 2. ing. The hot water tank 16 is provided with a water level sensor 28 for detecting the water level within the hot water tank 16 . This water level sensor 28 is located below and at a predetermined distance from the opening of the return pipe 22.
A space 29 is formed in the hot water storage tank 16 to receive water when the water in the heat collector 2 is drained.

に電磁弁２０が閉塞されて集熱完了となる。 Next, the operation will be explained. First, if the operation is started during heat collection, that is, when there is no water (or hot water) in the hot water storage tank 16, the solenoid valve 20 opens and the pump 10 operates, and the cold water from the cistern 15 is pumped into the orifice 21. Water is sent to the heat collector 2 under control at an extremely low flow rate (for example, about 1/min).
The high-temperature hot water heated by solar heat in the heat collector 2 is stored in the hot water storage tank 16 via the return pipe 22. When a predetermined amount of hot water is stored in the hot water storage tank 16, the water level sensor 28 is activated, the pump 10 is stopped, and the solenoid valve 20 is closed, completing heat collection.

度の湯を昇温するか否かを自由に選択できる。 When the tap 14 is opened at the time of hot water tap, the pump 10 is activated by detection by the flow rate sensor 25, and the three-way valve 19 is switched while the solenoid valve 20 remains closed, allowing the high-temperature hot water in the hot water tank 16 to reach a high temperature. Hot water will be dispensed at a flowing temperature (for example, about 10/min). The hot water from the hot water storage tank 16 can be heated to a temperature of 60 to 85° C. (for example, 60 to 85° C.) in the heat source section 13 and then released. That is, when the temperature of the hot water in the hot water storage tank 16 is lower than the set temperature of the thermistor 24, the heat source section 13 operates to raise the temperature, and conversely, when it is higher than the set temperature, the heat source section 13
does not operate, and the hot water in the hot water storage tank 16 is dispensed as is. The temperature setting in the thermistor 24 is variable, and it is possible to freely select whether or not to heat up the hot water at a predetermined temperature from the hot water storage tank 16.

By opening, the remaining hot water in the heat collector 2 is transferred to the hot water storage tank 1.

減を図ることができるものである。 That is, freezing of the heat collector 2 can be prevented simply by opening and closing the solenoid valve 27 as a valve body, and for example, the heat collector 2 can be prevented from freezing.
Compared to a system that prevents freezing by circulating water through intermittent operation at zero, operating costs are not required and costs can be reduced.

上昇を防止することができる。 Note that the circuit configuration is such that the electromagnetic valve 20 remains closed regardless of the water level sensor 28 except during heat collection, and the operation sequence is such that hot water is supplied to the hot water tank 16 only during heat collection. Further, the solenoid valve 20 is opened at the same time as the operation switch is turned on, and the pump 10 is started to operate several seconds after that, and when stopped, the solenoid valve 20 is opened several seconds after the pump 10 is stopped.
is configured to close the valve, thereby preventing an abnormal rise in pressure.

ることができる。 As described above, according to the present invention, when collecting heat, the inlet temperature of the collector can always be maintained at the temperature of the supplied water, that is, the cold water temperature before heating, so the logarithmic average temperature difference increases and the heat collection efficiency increases. In addition, since the cistern and the hot water tank are separated and the hot water tank is configured to be open to the atmosphere, the effect of water supply pressure on the hot water tank can be minimized, and it can be made of resin, reducing costs. In addition to being able to achieve weight reduction, the capacity of the hot water storage tank can be appropriately selected depending on the hot water supply load. Furthermore, a valve body provided between the electromagnetic valve and the heat collector allows water in the heat collector to be drained by returning it to the hot water storage tank that is open to the atmosphere to prevent freezing.
