At times, the method was to drain the water or keep circulating the water to prevent freezing, but now water in pipes or heat collectors can freeze due to malfunction of the automatic drain valve or poor circulation. It was often damaged. In addition, in order to reduce the above-mentioned freezing damage, the water in the cage heat tank is indirectly heated by circulating the antifreeze liquid as hot soot and heating the heat medium in the heat collector through a heat exchanger installed in the lower layer of the heat storage tank. A heat exchange system was also devised, but it was able to withstand freezing due to the circulation of antifreeze, but the efficiency of heating inside the heat exchanger was poor due to the heat exchange between the heating medium and water. Therefore, an open type system has been devised in which water is circulated directly through piping and into a heat collector, and when the heat collection is completed, it is collected into a heat storage tank.
This had good ripening efficiency and good freeze prevention. However, two pumps are required: a heat collection and circulation pump and a hot water supply pump.The hot water supply pump also requires a pressure tank that uses air pressure to stabilize the hot water supply, and the pressure tank holds air. Therefore, it is necessary to use a diaphragm with good airtightness or to supply air from the outside, which has many disadvantages, such as making the pump structure complicated and expensive. In order to eliminate the drawbacks of these open forced circulation type devices, the present invention uses a single pump for heat collection circulation and hot water extraction, and also automatically supplies air into the pressure tank to maintain stability over a long period of time. The purpose of this project is to provide an inexpensive solar water heater that can be used in many ways. Next, the structure of the present invention will be described.

The water in the return pipe 8 sucks air through the air inlet/outlet 16 and falls, and is collected into the heat storage tank 1. Next, a description will be given of opening the faucet 13 and the like to use the hot water in the heat storage tank 1. The pressure in the pressure tank 12 has stopped at a level higher than the set pressure of the pressure switch 20, and when the faucet 13 is opened, hot water is dispensed from the faucet 13, the pressure in the pressure tank 12 decreases, and the pressure switch 20 is opened. At the same time as the electromagnetic valve 15 closes, the pump 14 is activated, and hot water is supplied from the hot water outlet 5 to the pressure tank 12 and further to the faucet 13. and faucet 13
When the pressure in the pressure tank 12 becomes equal to or higher than the set pressure, the pump 14 stops and the solenoid valve 15 opens. When the water level in the heat storage tank 1 decreases with respect to the faucet 13, the ball tap 3 is connected and water is supplied from the water supply pipe 4 to the lower layer of the heat storage tank 1.
The high temperature water in the heat storage tank 1 is pushed upward, and when the water level reaches a certain level, the ball tap 3 closes to stop water supply. When the temperature of the high temperature sensing section 19 is lower than the temperature of the low temperature sensing section 17, the solenoid valve 15 closes and at the same time the pump 14 stops, and the water in the heat collector 6, outgoing pipe T, and branch section 10 flows into the heat storage tank 1. At the same time, air is introduced from the air inlet/outlet 16 and the branch portion 10 above the water surface of the heat storage tank 1 is also filled with air. When the faucet 13 is turned on in such a state, the solenoid valve 15 is closed and the pump 14 is activated, and the air in the branch part 10 has no place to escape and is supplied into the pressure tank 12.
As a result of this repetition, air is constantly supplied into the pressure tank 12. The present invention is an open circulation water heater that circulates water directly into the heat collector, so it has good heat collection efficiency, and when the heat collection is finished, the water in the heat collector 6, outgoing pipe 7, and return pipe 8 accumulates heat due to its heat retention properties. Since it is collected in the tank 1, there is little heat radiation and the heat collection efficiency is good.
When the outside temperature is lower than the temperature of the heat storage tank 1, there is no water in the heat collector 6, the outgoing pipe 7, and the return pipe 8, so no freezing occurs, so there is no damage due to freezing.

水器を提供するものである。Conventionally, two pumps, a circulation pump and a hot water extraction pump, are required, but in the present invention, one pump can operate everything. In addition, in order to discharge hot water with less water hammer and pressure fluctuations, the auxiliary tank required a pressure tank with good airtightness. A pressure tank with a simple structure is sufficient, it can be used stably for a long period of time, and no artificial air supply or maintenance is required. The present invention provides a water heater that can be stably used for a longer period of time, has good heat collection efficiency, and is inexpensive, without sacrificing the advantages of open circulation type water heaters.
