Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a drainage sealing device for a washing machine. Background Technology

[0002] As a common household appliance, the core function of a washing machine is to wash, rinse, and spin-dry clothes. Drainage is a crucial step in this process. Traditional washing machine drainage systems typically consist of a drain valve and a drain pipe. Their working principle involves controlling the opening and closing of the drain valve to retain and discharge washing water. Currently, most mainstream washing machine drain valves on the market use a solenoid valve or a motor-driven valve body structure. When drainage is needed, the solenoid or actuator is energized, pulling the valve core or rubber valve plug to open the drainage channel. When water needs to be stored, the power source resets, and the spring force or the elasticity of the rubber material itself presses the valve plug against the valve seat, thus achieving a seal. During the washing process, impurities such as lint, fibers, and small hard objects can easily enter the drain valve cavity with the water flow. These impurities may accumulate between the valve plug and the valve seat, hindering complete sealing or directly puncturing or scratching the rubber seal, causing seal failure. Therefore, we have redesigned a new drainage sealing device for washing machines. Utility Model Content
