Problems solved by technology

Ordinary solar water heaters are fixed on the roof of general buildings at a certain angle. Since the water storage tank of the solar water heater is exposed outdoors, the water pipes from the outlet of the water tank to the roof are prone to freezing in winter, which affects the use of hot water by users. Seriously, the water pipes will be frozen and cracked, wasting a lot of water. Therefore, to prevent the pipes from freezing and to make the water heater flow normally, usually wrap the pipes with an insulation layer or add an electric heating device, but the former method cannot effectively prevent the pipes from being damaged. The latter consumes power and does not save energy; and the water tank is used for a long time, and the dirt inside the water tank adheres to the water tank, which not only easily blocks the water pipe, causing the water in the water tank to be unable to be discharged, but also reduces the heating efficiency of the water in the water tank

Embodiment 1

[0048] Such as Figure 1 to Figure 7 As shown, the solar water heater antifreeze equipment with decontamination function of the present invention includes a water storage tank 4, the bottom of the water storage tank 4 is provided with a water guide pipe 1, and the top of the water guide pipe 1 is flush with the bottom end of the water storage tank 4, so The inner top wall of the water storage tank 4 is also provided with a fixed pipe 8, the axis of the fixed pipe 8 is on the same straight line as the axis of the aqueduct 1, and one end of the fixed pipe 8 is fixed to the inner top wall of the water storage tank 4. The other end is provided with a first bellows 6, which can expand and contract along the axial direction of the aqueduct 1, and a number of air holes 7 communicating with the interior are also provided on the outer wall of the fixed pipe 7. One end of the first bellows 6 is connected to the fixed pipe 7, and the other end is provided with a connector 5 that matches ...

Embodiment 2

[0050] On the basis of Embodiment 1, both sides of the connector 5 are provided with limiting grooves 18, and both sides of the inner wall of the aqueduct 1 are provided with first grooves, and the first grooves are provided with The third elastic member 20 is provided with a limiting ball 22 matching the limiting groove 18 on the third elastic member 20 , and the limiting ball 22 can be inserted into the limiting groove 18 .

Embodiment 3

[0052] On the basis of Embodiment 2, a second cavity 19 is also provided in the connector 5, and push rods 17 are arranged on both sides of the inner wall of the second cavity 19, and one end of the push rod 17 extends into the second cavity. In the second cavity 19, the other end is located in the limit groove 18. The movable rod 15 of conical structure is also provided in the second cavity 19. The diameter of the movable rod 15 gradually decreases along the direction of the push rod 17, and the movable rod 15 is movable. The maximum diameter of the rod 15 is consistent with the inner diameter of the cavity 19 , the movable rod 15 can move toward the direction of the push rod 17 , and push the push rod 17 to protrude from the limiting groove 18 .

Abstract

The invention discloses an antifreeze device for a solar water heater with decontamination function, which comprises a water storage tank, a water guide pipe is arranged at the bottom of the water storage tank, a fixed pipe is arranged on the inner top wall of the water storage tank, and a first corrugated pipe is arranged on the fixed pipe, The fixed pipe is also provided with air holes, the first corrugated pipe is provided with a connector, the connector can be connected to the water conduit, the inside of the connector is provided with a first cavity, the first cavity communicates with the first bellows, and the connector There is a guide rod and a through hole on the end surface of the guide rod, the guide rod moves and connects with the connector, and the other end extends into the aqueduct, and a fixed plate is also provided in the aqueduct, and a leak hole is also provided on the fixed plate, and the fixed plate and the A first elastic member is also arranged between the connecting heads, and a second bellows is also arranged in the first bellows. After the water heater is used, the present invention can empty the water in the aqueduct, prevent the aqueduct from freezing and cracking, and at the same time clean the dirt in the water storage tank to prevent the dirt from blocking the drainage aqueduct.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to antifreeze equipment for solar water heaters with decontamination functions. Background technique [0002] A solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters account for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required hot water. Solar water heaters are composed of vacuum heat collecting tubes, stainless steel water tanks and brackets. They are a major industry in the application of...
