The invention discloses an electromagnetic water drain valve. The electromagnetic water drain valve comprises a valve shell, a valve chamber, an electromagnetic coil, a reset spring, a steel shaft, a sealing plug and an electric heating film, wherein the valve shell is fixed at the upper part of the valve chamber; a water inlet is formed in the side part of the valve chamber, and a water outlet is formed in the bottom of the valve chamber; the electromagnetic coil is fixed in the valve shell; the steel shaft is arranged in an internal space of the electromagnetic coil; the reset spring is arranged between the top of the steel shaft and the inner top of the valve shell; the bottom of the steel shaft is fixedly connected with the sealing plug; the sealing plug is arranged in the valve chamber and is positioned above the water outlet; the electric heating film is fixed at the outer bottom of the valve chamber and encircles the water outlet. By fixing the electric heating film at the outer bottom of the valve chamber, the electromagnetic water drain valve is high in heat transfer efficiency, safe, stable and low in cost, and can also be normally operated at subzero temperature due to improvement of the freezing resistance.
Description
technical field [0001] The invention relates to an electromagnetic drain valve. Background technique [0002] Small electromagnetic drain valves are widely used in the home appliance industry. When it works, the electromagnetic coil is energized to generate a magnetic field, so that the steel shaft is sucked up and the sealing plug is opened to realize water discharge. However, when working at sub-zero temperatures, the residual water in the cavity will freeze, and the sealing plug and the water valve cavity will freeze together, causing the electromagnetic coil to fail to open when it is energized, and even causing damage to the drain valve over time. Contents of the invention [0003] The purpose of the present invention is to provide a safe, stable, low-cost electromagnetic water discharge valve that can work normally at sub-zero temperature. [0004] The technical solution for realizing the purpose of the present invention is: an electromagnetic drain valve, includin...
