Drainable and antifreezing solar water heater

Abstract

A drainable and antifreezing solar water heater comprises a solar water heater storage tank (1), an electromagnetic valve (2) and an air inlet pipe (3). The electromagnetic valve comprises a power source (11), a power source switch (10), an electromagnet (8), a sucking plate (7), a driving piece (6) and a driving disc (5). The electromagnet (8) is connected with a power source switch (10) and a power source (11) via leads and is fixed on the support, and the driving disc (5) is fixed on a valve handle (4). Since the air inlet pipe is communicated with a water pipe, water in the water pipe can be quickly drained out when the electromagnetic valve is turned off, and thus antifreezing effect is realized.

Description

Technical field: [0001] The invention relates to a solar water heater, in particular to a solar water heater capable of emptying and antifreezing. Background technique: [0002] Most of the household solar water heaters currently in use are installed on the roof. The distance from the roof to the room is long, and they need to be connected by water pipes. In cold seasons, the water pipes from the roof to the room tend to freeze, making the solar water heater unusable. . What was invented: [0003] The technical problem to be solved by the present invention is to provide an emptying and antifreezing device for solar water heaters, which can realize the antifreezing effect by emptying the water in the water pipe from the roof to the room, so that people in the industry love It can also be used normally in season, so that the clean energy of solar energy can be used more and better by people, and make more contributions to energy saving, emission reduction and environmental ...
