A water draining device of a washing machine, a washing machine and a control method

Abstract

Cleaning particles for cleaning a tub wall of a washing machine are provided between an inner tub and an outer tub. The cleaning particles are collected into a particle collecting chamber when draining water, and float upwards from a water inlet to be between the inner tub and the outer tub of the washing machine during water feeding. A water draining device comprises a drain valve body, a water inlet and a water outlet. The water inlet communicates with an outlet of the outer tub, the valve body has a particle collecting chamber communicating with the water inlet, a particle filtering structure is between the collecting chamber and the water outlet. The draining device further comprises a water / air access mechanism, the collecting chamber has a port in communication with the water / air access mechanism, and the water / air access mechanism controls water or air flow into the collecting chamber.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to a field of a washing machine, and especially relates to a water draining device of a washing machine, a washing machine and a control method.BACKGROUND OF THE INVENTION[0002]The space between an inner and an outer tub of the existing washing machine is a closed environment where only water can flow through. Due to the limitations of the above-mentioned structure of the washing machine and the specialty of the use environment, dirt will adhere to an outer wall of the inner tub and an inner wall of the outer tub after being used for three to five months, so as to breed bacteria in different degrees, and the vast majority of bacteria is harmful to the human body.[0003]With the improvement of people's living standards and the improvement of requirements of life quality, the solution of the hygiene problem of the washing machine has been very urgent. The survey of relevant research institutions on the internal environment of t...

AI Technical Summary

Benefits of technology

The present invention provides a water draining device for a washing machine that includes a particle collecting chamber to prevent the cleaning particles from hitting the inner wall of the machine while dehydrating. The device also utilizes a water flow / air flow to impact fibre debris groups and avoid bacteria breeding. The invention has a simple structure, low production and installation costs, and can accelerate the delivery of cleaning particles while keeping the drainage smooth.

Problems solved by technology

Due to the limitations of the above-mentioned structure of the washing machine and the specialty of the use environment, dirt will adhere to an outer wall of the inner tub and an inner wall of the outer tub after being used for three to five months, so as to breed bacteria in different degrees, and the vast majority of bacteria is harmful to the human body.

However, the structure of the above-mentioned washing machine will produce big noise during the high-speed dehydration process due to the rubber balls or flexible particles in the tubs are in a free scattered state after the drainage, it will increase the energy consumption of the washing machine and will affect the service life of the washing machine.

However, after a lot of experiments, the above-mentioned structure still has the following problems: 1. The cleaning particles as a whole adhere to the inclined inner wall and cannot immediately float up through the water inlet to the outer tub by the buoyancy during the water supply process of the washing machine, and the upper layer of the cleaning particles cannot float in a long time will cause all cleaning particles crowded under the inclined inner wall.

In particular, if the particles stay in the particle collecting chamber for a long period of time, the bottom layer of the cleaning particles are completely adhered to the bottom of the particle collecting chamber under extrusion, and is not conducive to their full delivery, 2.

When the washing machine is draining, line debris is easy to gather in the front of the filter structure and cannot be discharged due to the impact of cleaning particles.

Accumulation for a longer time will not only affect the drainage efficiency, but also will make the cleaning particles entangled which is not conducive to re-deliver.
