The utility model discloses still be equipped with intelligent electrical system for the start-up or the stop of control electric heater unit 8 and heating pump 11. Specifically, the method comprises the following steps:
a built-in electric heater 18 and a tank temperature sensor T1 for measuring water temperature are provided in the water storage tank 1, an upstream temperature sensor T2 and a downstream temperature sensor T3 are provided on the hot water circulation supply pipe 7 upstream and downstream of the electric heating device 8, respectively, and as shown in fig. 4, the tank temperature sensor T1, the upstream temperature sensor T2, the downstream temperature sensor T3, the electric heating device 8, the built-in electric heater 18 and the heating pump 11 are all connected to a controller K;
when the controller K detects that the water temperature is high enough through the tank temperature sensor T1, the upstream temperature sensor T2 and/or the downstream temperature sensor T3, the heating pump 11 can be started, and the heat collected by the solar heat collecting pipe 2 is completely used for heating the indoor without starting the electric heating device 8; at this time, because the water flow is fast, the bending structure formed by the inner conduit 52 and the outer sleeve 51 can continuously suck out the water in the water storage tank 1 by means of the siphon principle;
when the controller K detects that the water temperature is not high enough through the water tank temperature sensor T1, the upstream temperature sensor T2 and/or the downstream temperature sensor T3, the electric heating device 8 and/or the built-in electric heater 18 are/is started, and the indoor heating requirement is met by means of electric auxiliary heating; wherein, the electric heating device 8 is started to quickly heat water entering the room, which is beneficial to quickly raising the room temperature, and the built-in electric heater 18 is started to store heat by using the water in the water storage tank 1, which is mostly used in the period of valley electricity at night;

The controller K adopts an existing control chip, and the control procedure in the control process is a conventional technical means in the field, so that the control procedure does not need to be specifically disclosed in the application, and a person skilled in the art can also fully know how to implement the control procedure.
When the heating pump 11 and the electric heating device 8 are turned off, the water in the inner conduit 52 of the downcomer 5 flows into the balance tank 6 under the action of gravity (the balance tank 6 has a large enough capacity to accommodate the water emptied in the downcomer 5 and the upper conduit 4), so that the air in the balance tank 6 is compressed, and the air pressure is continuously increased until the air pressure can prevent the water in the inner conduit 52 from continuously flowing down; however, because the surface tension of the water is not enough to make the water adhere to the inner wall of the inner conduit 52, the water in the inner conduit 52 will slowly drop into the balance tank 6, and because the flow rate of the water flow caused by the dropping is extremely small, and because the bending structure formed by the outer sleeve 51 and the inner conduit 52 exceeds the liquid level, the upper end of the inner conduit 52 will not be subjected to the water pressure, so that the new water liquid will not be sucked into the inner conduit 52 from the water storage tank 1, and the inner conduit 52 will be gradually emptied; meanwhile, as the upper water pipe 4 is communicated with the bottom of the balance tank 6 through the water return pipe 10 and the heating terminal 9, the liquid level of the water in the upper water pipe 4 is gradually reduced to be flush with the liquid level of the balance tank 6 according to the principle of a communicating pipe, and automatic emptying is completed.
It can be seen that, the utility model provides an outdoor solar energy heating water system of intelligent control can the opportunity of intelligent control electricity auxiliary heating, can also rely on communicating pipe 12 principle, makes the water pipe 4 and the downcomer 5 homoenergetic of water tank empty automatically, does not need manual operation, and it is also province worry to save money.
Of course, the utility model can be used for heating in heating seasons, and can also be used for bathing in non-heating seasons.
As shown in fig. 1, the sewer pipe 5 is further connected with a hot water end of a mixing valve 12 through a branch pipeline 15, and a cold water end of the mixing valve 12 is connected with a tap water pipe 14 for mixing hot water and cold water to a proper temperature and then supplying domestic water to a water consumption point 16 (such as a faucet or a shower); after the hot water cup of the water storage tank 1 is consumed, the tap water pipe 14 can also replenish water to the water storage tank 1 through the water feeding pipe 4;
because the downcomer 5 of the present invention will be automatically emptied in the non-use state, so that the hot water end of the mixing valve 12 has no starting water flow, and the hot water in the water storage tank 1 cannot be sucked down according to the siphon principle, except for the scheme of installing a water pump, the present invention is provided with an electric drain valve 62 at the lower part of the balance tank 6, and is provided with a water-using electric control valve 17 on the branch pipeline 15, the electric drain valve 62 and the water-using electric control valve 17 are both in signal connection with a controller (which can be the aforementioned controller K, or another), when the domestic hot water is needed, the controller opens the electric drain valve 62, the air pressure in the balance tank 6 becomes negative, the hot water in the water storage tank 1 flows into the downcomer 5 under the atmospheric pressure, after a period of time (such as two seconds, which can be determined by actual measurement), the siphon effect can be formed, and the electric drain valve 62 can be closed, at this time or before the water use electrically controlled valve 17 is opened, the hot water is continuously introduced into the mixing valve 12 from the branch line 15. When the hot water is used up, the water using electric control valve 17 is closed, the hot water in the downcomer 5 can be automatically emptied to the balancing tank 6, and the balancing tank 6 is enabled to recover the positive pressure state.
Use the utility model discloses, because downcomer 5 is often in the evacuation state, it is hot water that the directness that consequently flows out water point 16 has fine use impression, and water waste is less moreover.
Certainly, the present invention may not be provided with an automatic emptying structure to be suitable for regions where freezing is not easy to occur, or adopt other anti-freezing modes, as shown in fig. 5, which is another embodiment of the present invention, and compared with the embodiment shown in fig. 1, the downcomer 5 is not composed of the outer sleeve 51 and the inner conduit 52, but is a straight pipe, which is inserted into the storage tank 1, and can lead out the water liquid in the storage tank 1; further, the balance tank 6 is not provided, and the structure and function of this embodiment are the same as those of the embodiment shown in fig. 1 except that the upper water pipe 4 and the lower water pipe 5 cannot be automatically emptied.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
