Non-pressure water-saving and antifreezing solar water heater capable of automatically outputting hot water firstly

Abstract

The invention provides a method for transforming a non-pressure solar water heater into a structure of automatically outputting hot water firstly for preventing freeze and saving water, belonging to the technical field of solar energy application. The invention is characterized in that the top of a water tank is provided with a clavate or an elliptical hole; a water level controller is arranged at the hole; the upper part of the lateral surface of the water tank is provided with a water outlet and a water outlet pipe; the top part of the water level controller is provided with a water inlet pipe and an air vent; the inner part of the water level controller is provided with a floating stick and a lever the resistance point of which is in the middle; the lower end and one side of the lower end of the water inlet pipe are respectively provided with a valve; the upper end of the water outlet pipe is provided with a n-shaped pipe; the air in the water outlet pipe flows downwards; the n-shaped pipe is arranged for exhausting water by being based on a siphon principle; the upper water level position in the water level controller is higher than the top part of the n-shaped pipe, and the lower water level position is the lowest water level position; the air vent ensures the non-pressure; the water level controller ensures automation; the water outlet on the upper part of the lateral surface of the water tank ensures that the hot water is output firstly; and the two valves ensure blank pipe freeze-proofing and water saving functions.

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] Pressureless solar water heaters are basically operated manually, which not only wastes water, time and energy, but also has disadvantages such as cold water coming out first, no antifreeze, and vacuum tubes are easy to burst. (3) Contents of the invention [0003] The technical task of the present invention is to provide a method of 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 completely solves the problems of the above-mentioned technologies Shortcomings. [0004] The technical solution adopted by the present inv...
