Description of drawings

Fig. 1 is the structure principle chart of solar water heater of the present utility model.

The specific embodiment

According to Fig. 1, provide preferred embodiment of the present utility model, and described in detail below, enable to understand better function of the present utility model, characteristics.

Fig. 1 is a structure principle chart of the present utility model.Running water pipe 9 among the figure, motor-driven valve 15, magnetic valve 14, heat collector 4 attemperaters 5 are cascaded.Attemperater 5, water pump 6, check valve 13, instant electric water heater 7, hand-operated valve 16 are cascaded.Magnetic valve 11 1 ends connect attemperater 5, and the other end connects together with the node that heat collector 4 is connected with magnetic valve 14.Magnetic valve 12 1 ends connect attemperater 5, and the other end connects together with the node that hand-operated valve 16 is connected with instant electric water heater 7.Check valve 13, instant electric water heater's 7 tie point links together with the tie point that motor-driven valve 15, magnetic valve 14 are connected.Temperature sensor 21 is contained in the top of heat collector, temperature sensor 22 is contained in the bottom in the attemperater 5, temperature sensor 23 is contained in instant electric water heater's delivery port, level sensor 31 is contained in the top of attemperater 5 inside, but reserve the space of heat collector 4 backwater, level sensor 32 is contained in the position that water level is preset in attemperater 5 inside, and level sensor 33 is contained in the bottom of attemperater 5 inside, overflow pipe 8 one ends and atmosphere communicate, and the other end is on the top of attemperater 5 inside.

When not working, motor-driven valve 15,

magnetic valve

11,12,14 are in off position.When sunlight was arranged, temperature sensor 21 reached design temperature, opens solenoid valve 14, motor-driven valve 15, and the size that motor-driven valve 15 is opened is adjusted according to the numerical value of temperature sensor 21, makes the water temperature that enters attemperater 5 keep constant substantially.When level sensor 31 perception water are full, motor-driven valve 15 cuts out, start water pump 6, opens solenoid valve 14, water in the attemperater is through water pump 6, check valve 13, magnetic valve 14, heat collector 4 is got back to attemperater 5, further improve water temperature, when temperature sensor 22 perception water temperatures reach setting value, switch off the pump 6, magnetic valve 14, opens solenoid valve 11, water in the heat collector 4 is got back in the attemperater 5 through magnetic valve 11, has avoided high-temperature scaling, and winter, low temperature also was opens solenoid valve 11, water in the heat collector 4 is got back in the attemperater 5 through magnetic valve 11, avoids finishing freezing bad heat collector 4.

During water, at first stop thermal-arrest, motor-driven valve 15, magnetic valve 14 are in off position.Pump handle hot water is given the user from attemperater through check valve 13, instant electric water heater 7, hand-operated valve 16 and is used.When temperature sensor 23 perception water temperatures are not enough, start the instant electric water heater automatically and make water temperature reach user's needs.

If in the pipeline be cold water, start water pump 6 earlier, open magnetic valve 12, the cold water in the pipeline is sent back to attemperater 5, temperature sensor 23 perception water temperatures reach instructions for use, close magnetic valve 12 again, open hand-operated valve 16, obtain suitable hot water.

If the water level in the attemperater is lower than designated water level 32, when water not, open motor-driven valve 15, magnetic valve 12, open instant electric water heater 7, make the hot water that heated enter attemperater 5, temperature sensor 23 is controlled the size of opening of motor-driven valves 15, so that enter the water temperature that attemperater 5 reaches setting.The instant electric water heater is with regard to unnecessary very big power when reusing.Overflow pipe 8 is for logical atmosphere in the attemperater, keeps normal pressure to design.

Above-described, be preferred embodiment of the present utility model only, be not in order to limiting scope of the present utility model, the foregoing description of the present utility model can also be made various variations.Be that every simple, equivalence of doing according to the claims and the description of the utility model application changes and modification, all fall into the claim protection domain of the utility model patent.
