An embedded solar water heater

technical field

The utility model relates to a vacuum tube solar water heater, in particular to an embedded solar water heater.

Background technique

At present, solar vacuum tube water heaters on the market are all installed on the roof, and cannot be integrated with the roof, which affects the overall aesthetics. And the water tank of solar water heater also does not have the structure that places indoor.

Contents of the invention

In view of the above shortcomings, the utility model provides an embedded solar water heater. The heat collector and the water tank adopt a split structure. The heat collector is light in weight and can be embedded in the roof for installation and integrated with the roof.

The technical scheme that the utility model adopts is:

An embedded solar water heater, which includes a heat pipe type glass vacuum heat collecting tube 1, a heat collecting horizontal box 2, and a mounting bracket 3, and is characterized in that the water heater also includes an insulating water tank 8, a circulation pump 9, a controller 4, low temperature, and water level sensors 7. The high temperature sensor 12, the thermal insulation water tank and the heat collecting horizontal tank are connected through the water inlet and outlet pipes, the circulation pump 9 is set on the water inlet pipe between the two tanks, the thermal insulation water tank 8 is connected with the tap water upper water pipe 10 and the hot water supply pipe 11. The high temperature sensor 12 is located in the heat collecting horizontal box 2, the low temperature and water level sensor 7 is located in the heat preservation water tank 8, and the controller 4 is connected with the low temperature and water level sensor 7, the high temperature sensor 12 and the tap water supply valve 13 of the heat preservation water tank 8.

The high temperature sensor 12 is located in the heat collecting horizontal box 2 near the water outlet pipe 6 port of the heat collecting horizontal box, and the low temperature and water level sensor 7 are located at the middle and lower part of the heat preservation water tank 8 .

The heat pipe type glass vacuum heat collecting tube 1, the heat collecting horizontal box 2 and the mounting bracket 3 can be covered with a glass cover. Insulated water tank 8 is an indoor installation type water tank.

The advantage of the utility model solar water heater is:

The thermal insulation water tank of the utility model can be placed indoors, and the heat collecting part is small in size and light in weight; the heat collecting part is embedded in the building and integrated with the building; there is no water in the vacuum glass heat collecting tube, and the damage of the vacuum glass heat collecting tube will not affect the operation of the system; Although the circulation pump is added, the number of cycles is proportional to the heat collection, and the power consumption increases with the increase of the heat collection, but the power consumption is not much.

Since the solar water heater is integrated with the building, a skylight can be opened on the roof where the heat collector is installed, and glass can be added to the heat collector to achieve the purpose of lighting and heat preservation; the heat collector can also be embedded in the wall or hung outside the balcony , The heat preservation water tank is placed inside the house.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1, Figure 2 and Figure 3, the vacuum tube solar water heater of the present invention includes a heat pipe type glass vacuum heat collecting tube 1, a heat collecting horizontal box 2, a mounting bracket 3, a controller 4, and a heat collecting horizontal box water inlet pipe 5 , heat collecting horizontal box outlet pipe 6, low temperature, water level sensor 7, heat preservation water tank 8, circulation pump 9, water supply pipe 10, water supply pipe 11, high temperature sensor 12 and water supply valve 13, and its heat preservation water tank 8 is placed in the house, in the water tank The water in the heat collecting horizontal tank is sent to the heat collecting horizontal tank 2 by the circulating pump 9 through the water inlet pipe 5 of the heat collecting horizontal tank, and the hot water in the heat collecting horizontal tank 2 is returned to the thermal insulation water tank 8 through the thermal collector horizontal tank outlet pipe 6, and the thermal thermal water tank 8 has another The upper water pipe 10 is used for replenishing cold water, and the water supply pipe 11 is also used for outputting hot water.

The solar water heater can be embedded in the pit reserved on the roof, fixed by embedded parts, and its thermal insulation water tank 8 is placed in the house, which reduces the weight installed on the external water heater. The heat collector of this solar water heater, i.e. the heat pipe type glass vacuum heat collecting tube 1, the heat collecting horizontal box 2 and the mounting bracket 3 can be covered with a glass cover. Thermal insulation water tank 8 can be indoor installation type water tank.

The heat collecting horizontal box 2 is arranged vertically with the heat pipe type glass vacuum heat collecting tube 1, the heat collecting tube 1 is inserted into the heat collecting horizontal box 2, and the absorbed heat is transferred to the water in the heat collecting horizontal box 2, and the water in the heat collecting horizontal box 2 When the temperature rises, the heat is temporarily stored. When the temperature rises, the circulating pump 9 operates to deliver hot water to the heat preservation water tank 8, and cold water enters the heat collecting horizontal tank 2.

The high temperature sensor 12 is located in the heat collecting horizontal box 2 near the water outlet pipe 6 port of the heat collecting horizontal box, and the low temperature and water level sensor 7 are located at the middle and lower part of the heat preservation water tank 8 .

When the temperature difference between the temperature of the high-temperature sensor 12 and the low-temperature sensor 7 was higher than the pump starting set point (for example, 10 degrees), the controller 4 controlled the circulation pump 9 to start, and the circulation direction was shown by the arrow in Fig. 1: in the heat preservation water tank 8 The cold water is delivered to the heat collecting horizontal tank 2 by the circulation pump 9 through the heat collecting horizontal tank inlet pipe 5, and the hot water in the heat collecting horizontal tank 2 returns to the heat preservation water tank 8 through the heat collecting horizontal tank outlet pipe 6, when the high temperature sensor 12 When the temperature difference between the temperature and the low temperature sensor 7 is lower than the pump stop set value (for example, 3 degrees), the controller 4 controls the circulating pump 9 to stop running. When low temperature, water level sensor 7 detected that thermal insulation water tank 8 was anhydrous (or water is not full of), controller 4 controls running water supply valve 13 to open, and cold water replenishment enters thermal insulation water tank 8.
