Problems solved by technology

Since the water tank is an airtight container, it can only be replaced once scaling cannot be cleaned, and the water tank is the main part of the solar water heater. Replacing the water tank is no different from replacing the whole solar water heater.

Embodiment Construction

[0015] Refer to attached figure 1 , a solar water heater self-cleaning water tank structure, including a water tank 10, the water tank 10 is spherical, the lower end is provided with an opening 11, and the outer surface of the opening 11 is provided with threads.

[0016] The water inlet and drainage system 20 includes two water inlet pipes 21 and a sealing end 22. The two water inlet pipes 21 extend into the water tank body 10. The wall of the water inlet pipe 21 is provided with several water outlet holes 211 with small diameters and different directions. During water intake, because the water inlet pipe 21 pipe diameter is bigger, and the water outlet hole 211 diameter is fine and small, under the effect of water pressure, the water flow velocity of the water outlet hole 211 is bigger, forms scouring force to the inner wall of water tank body 10; 211 are in different directions, forming a full-area scour to the inner wall of the water tank body 10, effectively preventing th...

Abstract

The invention relates to a structure of a self-cleaning tank of a solar water heater, which comprises a water tank body, a water inlet drainage system and a control system. The water tank body is of a round spherical shape; the lower end of the water tank body is provided with an opening; and the outer lateral surface of the opening is provided with threads. The water inlet drainage system comprises water inlet pipes and a sealed end, wherein the water inlet pipes extend into the water tank body; the water inlet pipe body wall is provided with a plurality of water outlet holes with fine diameters and different directions; the sealed end is U-shaped, the inner lateral surface of the sealed end is provided with threads; and the threads are matched and fixedly sealed with the threads positioned on the outer lateral surface of the opening. Conical steps are arranged between the two water inlet pipes to form a water dirt discharged opening. The control system is arranged on the conical steps between the two water inlet pipes, and comprises a cone, a connecting line and a bobber body. The water tank body is only provided with a simple mechanism which can clean away furr in the water tank body automatically and effectively.

Description

technical field [0001] The invention relates to a solar water heater water tank structure, in particular to a solar water heater water tank structure with self-cleaning function. Background technique [0002] The utilization of solar water heater is very popular among people, but known solar water heater, especially the solar water heater that adopts vacuum heat collecting tube, most of them all are that vacuum heat collecting tube is inserted into the water tank that has shell, insulating layer and liner, and water tank injects cold water Finally, part of the water enters the vacuum heat collecting tube, and the vacuum heat collecting tube heats the water in the tube under the condition of effectively collecting sunlight, and generates the power of automatic thermal cycle, the hot water continuously enters the water tank, and the cold water in the water tank enters the vacuum again. In the heat collecting tube, the cycle reciprocates. Since the water contains a large amoun...
