Pipe defroster of solar water heater and using method

Abstract

The invention discloses a pipe defroster of a solar water heater and a using method. The structure of the pipe defroster comprises a water inlet pipe (1), a water outlet pipe (2), a common water pipe (3), and a water inlet valve (4) and a water outlet valve (5) which are connected with the water inlet pipe (1), the water outlet pipe (2) and the common water pipe (3), wherein a water-level floater (605) automatically displays water level in a storage water tank (6) by the control of a core wire of a water-level state control wire (11) over the movement of a water-level indicator terminal (72) in a water-level indicator (7); and a control wrench (81) in a water controller (8) controls hot water to flow or stay through the drawing of a water control piston (93) in the storage water tank (6) by the core wire of a water control wire (10). The pipe defroster of the solar water heater has a purely mechanical structure, the water inlet pipe and the water outlet pipe are shared, and the water level condition in the outdoor storage water tank can be known indoor at any time; the outlet water is the hot water when water is used, so the waste of cold water is avoided; and the water in the pipes is automatically evacuated at ordinary times without using electric power, and the defroster is particularly suitable for the defrosting of the water outlet pipe of the solar water heater in cold areas.

Description

technical field [0001] The invention relates to the technical field of solar water heater access and water pipeline antifreeze Background technique [0002] In the cold winter, the upper and lower pipes leading to the interior of the solar water heater's water tank are very easy to freeze and block, which brings many difficulties to the use of the water heater. In order to overcome the freezing blockage of the upper and lower pipelines, many new technologies have been adopted and introduced, but the following problems are also encountered, such as: [0003] a. Add extra-thick insulation sleeves outside the upper and lower pipes to prevent freezing and blockage; add hollow pipes inside the upper and lower pipes to input indoor heating for heat preservation and anti-freezing blockage. But when running into the cloudy and snowy weather that lasts several days, still cause the freezing blockage of upper and lower pipeline; Adopt siphon emptying method to prevent freezing and bl...

AI Technical Summary

Problems solved by technology

Due to the need for electric energy during use, it will inevitably encounter line aging, leakage, etc., which will bring unfavorable factors to personal safety.

[0007] Each of the above-mentioned methods has certain practical significance, but they all have deficiencies, and most of the methods cannot identify the level of the water level in the water storage tank, and rely on human subjective judgment

In short, in order to solve the antifreeze problem of solar water heater pipelines, people have carried out a lot of practice, but have not yet found a perfect solution
