In order to facilitate the understanding of those skilled in the art, the utility model is described in detail below.

Please also refer to Figure 4, which is a schematic diagram of an application example of an integrated system composed of solar energy and electric energy water heaters provided in the utility model; due to different temperatures, the water temperature in the solar water heater storage tank is different, and the water temperature of tap water is also different , the present embodiment mainly adjusts the energy-saving integrated valve according to different water temperatures, changes the flow path of tap water in the water inlet pipe, and forms different flow patterns, thereby maximizing the use of solar energy and saving electric energy. That is to say, in this embodiment, the solar water heater and the electric water heater are connected together through an energy-saving comprehensive valve to form an integrated system, and its basic structure specifically includes:

Solar hot water storage tank 41 (i.e. the water storage tank of solar water heater), electric hot water storage tank 42 (i.e. the water storage tank of electric water heater) and energy-saving integrated valve 43, wherein, energy-saving integrated valve 43 is made up of three fork mouth water valves, namely The first Sanchakou water valve 1, the second Sanchakou water valve 2 and the third Sanchakou water valve 3, the solar hot water storage tank 41 includes a water inlet 411 and a water outlet 412, and the electric hot water storage tank 42 includes an inlet Water end 421 and water outlet end 422.

For ease of description, it is assumed that the water temperature in the storage tank of the solar water heater is C1, the water temperature of the tap water is C2, and the lowest water temperature required by people for normal bathing is C3.

The first case: when C1≥C3, that is, only heating the water in the storage tank of the solar water heater can reach the temperature of the water required for normal bathing. The water valve and the third fork water valve make tap water flow into the solar water heater storage tank 41 through the first fork water valve 1 from the water inlet pipe 44 and heat it. The outlet port 412 flows out, directly flows out through the second fork water valve 2 and the third fork water valve 3, and mixes tap water through the mixing valve to output the water temperature required for people to bathe; the specific flow route is:

Tap water inlet pipe 44-1-411-solar water heater storage tank 41-412-2-3-water outlet 45.

Tap water inlet 44-1-411-solar water heater storage tank 41-412-2-46-421-electric water heater storage tank 42-422-47-3-water outlet 45.

The third case: when C1≤C2, the temperature of the water flowing out from the solar water storage tank is lower than that of the tap water, and the tap water needs to be heated directly. In addition, if the phenomenon of frozen pipes occurs, the following adjustments are also applicable: the tap water passes through the first fork water valve 1 to the pipeline 48, then enters the electric water heater storage tank through the pipeline 46 to be directly heated, and then flows out from the pipeline 47 through the third fork water valve 3 The outlet pipe is used by people, and the specific flow route is:

But in order to avoid waiting, if the electric water heater is kept powered on, it will consume electricity. For this reason, the utility model proposes a built-in timing device on the electric water heater, and people can pre-set the time on the timing device according to the needs of their own specific bathing time, so that the timing device will automatically start a period of time before the specified time. The power supply makes the electric water heater start to work. When people need to take a bath, the water temperature just reaches the set temperature, which is just for use. After use, the power is turned off. This not only satisfies people's need to obtain hot water in time when bathing, but also greatly shortens the heat preservation time and saves electric energy.

It can be seen from the above-mentioned embodiments that, first of all, because the energy-saving integrated valve is proposed in the product of the utility model, its structure is simple and durable; Water needs for bathing throughout the year.

Secondly, the product of the utility model is antifreeze, easy to operate, and high in cost performance.

Second, a timer can be installed in the integrated system. Through the timer, we can control the time of the electric water heater, so that the electric water heater starts to heat automatically before the set time, which greatly reduces the heat preservation time and also achieves the effect of energy saving;

Third, for a solar water heater with electric heating equipment, if the water temperature in the water storage tank of the solar water heater cannot reach the appropriate temperature, the electric heating equipment it carries will heat the water source outdoors, and under the same circumstances, the integrated The system will lead the water in the storage tank of the solar water heater to the electric water heater, and the electric water heater will carry out secondary heating indoors. The electric energy consumed for heating and keeping warm indoors is on average lower than that for heating and keeping warm outdoors.

It can be seen that, firstly, the product of the present utility model has changed the water circulation mode of the traditional water heater, successfully achieved different treatments under different water temperature conditions, and further reduced the daily electricity consumption of residents on the basis of providing convenience.

Second, the product of the utility model solves the problem of limited use of solar water heaters in winter, and meets the requirement that solar water heaters can be used at any time throughout the year.
