Anti-freezing and water-saving solar water heater capable of discharging hot water firstly in automated mode

Abstract

The invention provides an anti-freezing and water-saving method capable of discharging hot water firstly in an automated mode, which is changed from a non-pressure solar water heater. The method is characterized in that the upper part of the side face of a water tank is provided with a water outlet and a water discharge pipe, and the top of the water tank is provided with a controller water tank; the top of the controller water tank is provided with a breather pipe and a water inlet pipe, and a main floating ball, an assistant floating ball and a lever are arranged in the controller water tank; a main body of the controller water tank is arranged in a thermal insulation layer, and a thermal insulation cover is arranged on a thermal insulation skin; the lower end of the water inlet pipe is provided with a water control valve, and one side of the lower end of the water inlet pipe is provided with an anti-freezing valve; and the upper end of the water discharge pipe is provided with an n-shaped pipe, the lower end of the water discharge pipe is provided with an air release valve, one side of the lower end of the water discharge pipe is connected with a water mixing valve, and air in the water discharge pipe flows downwards. A pressure-differential type water surface control valve for controlling the water surface also can be arranged in the controller water tank. In the process of bathing, the water surface position in the controller water tank needs to be higher than the top of the n-shaped pipe. The automation of the controller water tank is guaranteed; a situation that hot water is discharged from the water outlet firstly is guaranteed; and due to the anti-freezing valve and the water control valve, anti-freezing and water-saving functions are guaranteed.

Description

(1) Technical field [0001] The invention relates to the application technology of solar energy, in particular to a method for transforming a pressureless solar water heater into automatic operation, hot water discharge first, antifreezing, water saving and anti-vacuum tube bursting. (2) Background technology [0002] The pressureless solar water heater is basically operated manually, which not only wastes water, time and energy, but also has the disadvantages of cold water coming out first, no antifreeze, and the vacuum tube is easy to burst. (3) Contents of the invention [0003] The technical task of the present invention is to provide a method for transforming a pressureless solar water heater with manual operation of cold water first into an automatic work, hot water first, antifreeze, water saving and anti-vacuum tube bursting, which solves the problems of the above-mentioned technology shortcoming. [0004] The technical solution adopted by the present invention to ...
