Washing machine door-end sprinkler, working method and washing machine

Abstract

The invention provides a washing machine door-end sprinkler, a working method and a washing machine. The door-end sprinkler comprises a sprinkling pipe communicating with a water inlet pipe, and a nozzle arranged at the tail end of the sprinkling pipe. An electromagnetic valve is arranged between the sprinkling pipe and the water inlet pipe. A ventilation pipe having a ventilation port is connected to the sprinkling pipe. A ventilation valve capable of opening and closing the ventilation port is arranged in the ventilation pipe. The ventilation valve is opposite to the electromagnetic valve in opening and closing states. The ventilation pipe and the ventilation valve are arranged, and the ventilation valve and the electromagnetic valve are opposite in opening and closing state, so that the ventilation valve is closed when the electromagnetic valve is opened; in this case, water flows through the sprinkling pipe and is ejected via the nozzle; the ventilation valve is opened when the electromagnetic valve is closed; in this case, the sprinkling pipe communicates with the external at the ventilation pipe such that water left in the sprinkling pipe flows out via the nozzle. Thus, residual water can be discharged timely, and influence of the residual water on a user and clothes is avoided; the washing effect is ensured, and the customer satisfaction is enhanced.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a door-end spraying device, a working method of the door-end spraying device, and a washing machine with the door-end spraying device. Background technique [0002] During the washing process of the drum washing machine, due to reasons such as gaps and water flow angles, washing powder foam, thread debris, etc. adhere to the observation window and window pad; due to the existence of foam and residual detergent, it seriously affects the washing effect and pollutes the clothes. It is easy to re-contaminate the clothes when taking them out, and the lint and sand left over from washing are easy to accumulate in the window mat, which is easy to cause bacterial growth and affect the washing effect and healthy life. [0003] For the problem of residual detergent and foam between the observation window and the window gasket sealing ring, it is generally adopted to co...

AI Technical Summary

Problems solved by technology

When opening the doors and windows to pick up clothes, the residual water in the spray pipe will flow out due to the vibration, and the hands, arms or clothes will be wet, and the residual water that does not flow out will easily breed bacteria, affect the washing effect, and reduce customer satisfaction
