[0002] Solar water heaters are energy-saving and environmentally friendly, and are widely used in various places that require hot water. However, traditional solar water heaters have poor heating effects and can only maintain a small amount of water at the required temperature. By concentrating sunlight and shining it on the solar tubes, the absorption efficiency of solar energy is improved, thus solving the problem of poor heating effect of traditional water heaters. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a solar water heating supply device, including a base plate, a water storage tank fixedly connected to the upper surface of the base plate, a water storage cavity inside the water storage tank, a solar heat absorption tube on the left side of the water storage tank, a water pump fixedly connected to the upper surface of the base plate, the water inlet of the solar heat absorption tube connected to the water pump through a second water supply pipe, the water outlet of the solar heat absorption tube connected to the water storage tank through the second water supply pipe, and a first water supply pipe fixedly connected between the water pump and the water storage tank, thereby enabling the water in the water storage cavity to be pumped into the solar heat absorption tube to absorb solar energy for heating, and then returned to the water storage cavity for storage;

[0005] A reflector is provided on the lower side of the solar heat absorber tube. The reflector is fixedly connected to a first fixing frame, which is fixedly connected to the solar heat absorber tube and serves as a support. In addition to the solar heat absorbed by the solar heat absorber tube itself, a transparent and smooth film is attached to the inside of the reflector. The transparent and smooth film reflects sunlight onto the solar heat absorber tube, which improves the solar heat absorption efficiency and increases the hot water storage capacity.

[0007] Advantageously, the reflector frame is provided with a through hole, through which the second water supply pipe passes and is sealed to the solar heat absorption pipe;

[0008] Advantageously, a second fixing frame is fixedly connected to the rear side of the water storage tank, and the second fixing frame is fixedly connected to the second water supply pipe to play a fixing role;

[0009] Beneficially, a water temperature monitor is fixedly connected to the lower end face of the water storage chamber, which monitors the temperature of the water in the water storage chamber. A water pressure monitor is also fixedly connected to the lower end face of the water storage chamber, which monitors the water pressure in the water storage chamber, thereby determining the water volume.

[0010] Advantageously, a second solenoid valve communicating with the water storage chamber is fixedly connected to the upper end face of the water storage tank, and a water inlet pipe is fixedly connected to the upper end face of the second solenoid valve, so that water can be replenished in a timely manner.

[0011] Advantageously, a first solenoid valve is fixedly connected to the front side of the water storage tank, and the first solenoid valve is fixedly connected to a water outlet pipe. Hot water in the water storage chamber is delivered by opening the first solenoid valve.

[0013] Advantageously, a controller is fixedly connected to the upper surface of the base plate, and the controller controls the first solenoid valve, the second solenoid valve and the water pump.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model incorporates a reflector frame, a solar heat-absorbing tube, and a water pump. The water pump draws water from the bottom of the storage chamber to the solar heat-absorbing tube, and then the water flows into the storage chamber from the top. The solar heat-absorbing tube absorbs the sunlight it receives and also absorbs the sunlight reflected by the reflector frame, thereby improving the temperature absorption efficiency and heating more water.

[0016] This utility model incorporates a water storage tank, a second solenoid valve, and a first solenoid valve. A water temperature monitor tracks the water temperature in the storage chamber, while a water pressure monitor tracks the water pressure. When the water temperature is low, a water pump is activated to extract water for solar energy absorption and heating. When the water pressure is low, the second solenoid valve is opened to replenish water into the storage chamber through the inlet pipe, thereby achieving automatic heating and water replenishment.

[0027] A reflector frame 102 is provided on the lower side of the solar heat absorber tube 104. The reflector frame 102 is fixedly connected to a first fixing frame 105. The first fixing frame 105 is fixedly connected to the solar heat absorber tube 104 and serves as a support. In addition to the solar heat absorbed by the solar heat absorber tube 104 itself, a transparent and smooth film 103 is attached to the inside of the reflector frame 102. The transparent and smooth film 103 reflects sunlight onto the solar heat absorber tube 104, thereby improving the solar heat absorption efficiency and increasing the hot water storage capacity.

[0028] The transparent and smooth film 103 can quickly clean the dust on its surface under rainwater washing, ensuring the reflection effect of sunlight;

[0029] The reflector frame 102 is provided with a through hole 113, and the second water supply pipe 119 passes through the through hole 113 and is sealed to the solar heat absorption pipe 104.

[0030] A second fixing frame 118 is fixedly connected to the rear side of the water storage tank 106. The second fixing frame 118 is fixedly connected to the second water supply pipe 119 and serves to fix it.

[0031] A water temperature monitor 116 is fixedly connected to the lower end face of the water storage chamber 115. The water temperature monitor 116 monitors the temperature of the water in the water storage chamber 115. A water pressure monitor 117 is fixedly connected to the lower end face of the water storage chamber 115. The water pressure monitor 117 monitors the water pressure in the water storage chamber 115, thereby determining the water volume.

[0032] The upper end face of the water storage tank 106 is fixedly connected to a second solenoid valve 111 that communicates with the water storage chamber 115. The upper end face of the second solenoid valve 111 is fixedly connected to a water inlet pipe 112, so that water can be replenished in a timely manner.

[0033] A first solenoid valve 109 is fixedly connected to the front side of the water storage tank 106. The first solenoid valve 109 is fixedly connected to a water outlet pipe 110. Hot water in the water storage chamber 115 is delivered by opening the first solenoid valve 109.

[0034] Four support frames 101 arranged in a circular array are fixedly connected between the upper surface of the base plate 100 and the reflector frame 102. The support frames 101 serve to support the reflector frame 102.

[0035] A controller 108 is fixedly connected to the upper surface of the base plate 100. The controller 108 controls the first solenoid valve 109, the second solenoid valve 111, and the water pump 107.

[0036] Working principle:

[0037] First, the second solenoid valve 111 is opened by the controller 108, and an appropriate amount of water is introduced into the water storage chamber 115 through the water inlet pipe 112. The water temperature is monitored by the water temperature monitor 116 and the water pressure is monitored by the water pressure monitor 117. After adding an appropriate amount of water, the second solenoid valve 111 is automatically closed.

[0038] When the water temperature monitor 116 detects that the water temperature is insufficient, it starts the water pump 107. The water pump 107 draws water from the water storage chamber 115 from the first water supply pipe 114 to the second water supply pipe 119, and then into the solar heat absorption pipe 104. The solar heat absorption pipe 104 absorbs sunlight and also absorbs sunlight reflected by the reflector 102, thereby improving the efficiency of solar heating. The heated water is then fed into the water storage chamber 115 from the top through the second water supply pipe 119 at the other end. This cycle continues until the water temperature in the water storage chamber 115 reaches the set value, at which point the cycle stops. After the water temperature drops, the cycle automatically restarts.

[0039] The transparent and smooth film 103 can ensure the reflective effect of the reflector frame 102 under rain washing, and the hot water in the water storage chamber 115 can be discharged from the water outlet pipe 110 by opening the first solenoid valve 109.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
