Embodiment Construction

[0008] As shown in the figure is an antifreeze device for a solar water heater implemented by the present invention, which is installed on the water storage tank of the solar water heater, wherein the electromagnetic switch includes a coil 1, a power supply 2, a power switch 3, a valve 4, a suction plate 5, Spring 6, switch, coil, and power supply are connected together with wires. The suction plate is made of ferrous material. The suction plate is fixed on the valve handle. When the power is turned on and the switch is turned on, electromagnetic force is generated in the coil to attract the suction plate to move forward, thereby opening the valve. , so that the hot water in the solar water heater flows out, a spring is installed on the suction plate, and the other end is fixed on the bracket. When the power is disconnected, the spring pulls the suction plate back to its original position, and the valve is closed.

Abstract

An anti-freezing device of a solar water heater is installed on a water storage tank of the solar water heater; a coil 1, a power source 2, a power switch 3, a valve 4, an actuation board 5 and a spring 6 are arranged in an electromagnetic switch; the switch, the coil and the power source are connected together through wires; the actuation board is made of iron materials and fixed on a valve handle; the power switch is turned on, electromagnetic force is generated in the coil and attracts the actuation board to move forwards, and therefore the valve is opened and hot water in the solar water heater flows out; the spring is installed on the actuation board, the other end of the spring is fixed on a support, when the power source is turned off, the spring pulls the actuation board to return to the original position, and the valve is closed.

Description

Technical field: [0001] The invention relates to an electromagnetic switch, in particular to an antifreezing device for a solar water heater. Background technique: [0002] Household solar water heaters that are commonly used now are mostly installed on the roof. From the roof to the room, they need to be connected by general water pipes. In the cold season, the water in the water pipes that come down from the water storage tank of the solar water heater often freezes. Solar water heaters are not available. What was invented: [0003] The technical problem to be solved by the present invention is to provide an antifreeze device for solar water heaters, which can realize the antifreeze effect by emptying the water in the water pipe between the solar water heater and the room, so that the solar water heater can also be used in winter. Make better and more use of clean energy such as solar energy, and make more contributions to energy conservation, emission reduction, and en...
