Problems solved by technology

However, in the northern regions where the winter is cold, solar water heaters are faced with the problem of pipeline freezing. In addition, a part of cold water needs to be released before hot water can be released before use, which hinders the promotion of solar water heaters.
Existing antifreeze valves are expensive, complex and easily damaged, difficult to popularize, and cannot realize automatic antifreeze and instant hot water

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] Such as figure 1 Shown: when replenishing water for the inner cylinder 23 of the water tank, a momentary forward current is artificially supplied to the electromagnet 1, so that the magnetism of the lower half of the electromagnet 1 is opposite to that of the upper half of the permanent magnet 6. At this time, the permanent magnet 6 will The upward movement is attracted by the electromagnet 1. Due to the non-contact attraction between the permanent magnet 6 and the upper silicon steel sheet 4, the rubber pad 16 is closely connected with the lower port of the outer cylinder 8 of the pull rod, and the water flow can pass through the temperature sensor switch through the upper and lower water pipes 13. 14 enters the water and air chamber 15, and then flows into the inner cylinder 23 of the water tank through the upper port of the water inlet and outlet pipe 9 through th...

Abstract

An automatic anti-freezer of a solar water heater comprises an emptying valve, an upper water pipe, a lower water pipe and a temperature inductive switch, wherein the emptying valve is built in a water tank, the upper water pipe and the lower water pipe are connected with a water source, and the temperature inductive switch is arranged between the upper water pipe and the lower water pipe and outside the water tank. The emptying valve is provided with an emptying valve outer shell, an electromagnet, an upper silicon steel sheet, a permanent magnet, a lower silicon steel sheet, a pull rod, a rubber gasket, a piston bin, a steam bin, a water inlet and outlet pipe and a wire. The emptying valve can complete operation through instant power supply, and the aim of freezing prevention and the aim of obtaining instantly-available hot water are achieved through control of the emptying valve and the temperature inductive switch. The automatic anti-freezer is convenient to refit, not prone to damage, capable of saving energy, environmentally friendly, free of manual operation, capable of being used at all seasons and in any place, simple in structure, low in cost and easy to popularize.

Description

technical field [0001] The invention relates to an auxiliary device for a solar water heater, in particular to an automatic antifreeze device for a solar water heater. Background technique [0002] Household solar water heaters have developed rapidly over the past 30 years and have been widely used in urban and rural households. However, in the northern regions where the winter is cold, solar water heaters are faced with the problem of pipeline freezing, and before use, a part of cold water needs to be released before hot water can be released, which hinders the promotion of solar water heaters. The existing antifreeze valve has high cost, complex structure and easy damage, and is difficult to popularize, and cannot realize automatic antifreeze and instant hot water. Therefore, there is an urgent need in the market for a solar water heater that can automatically prevent freezing and can use hot water immediately. Contents of the invention [0003] The object of the prese...
