Drainage device of washing machine and washing machine

Abstract

The invention discloses a drainage device of a washing machine and the washing machine. The washing machine comprises an outer barrel, an inner barrel and an impeller, wherein cleaning particles for cleaning the walls of the barrels are arranged between the inner barrel and the outer barrel; an outfall is arranged at the bottom part of the outer barrel; the drainage device comprises a particle collecting and discharging chamber for containing the cleaning particles when dewatering and enabling the cleaning particles to float into the outer barrel to clean the wall of the barrel by buoyancy force when feeding water, and a drainage chamber; the particle collecting and discharging chamber is communicated with the outfall through an interconnection pipe; the particle collecting and discharging chamber has an inclined inner wall structure capable of enabling the cleaning particles to float along with raised water level so as to enter into the interconnection pipe along the inner wall and enter into the outer barrel via the outfall; an opening communicated with the outside is arranged at one side of the particle collecting and discharging chamber opposite to the drainage chamber; the opening is provided with a closable sealing cover; and the sealing cover is on the inner wall of the particle collecting and discharging chamber and is in an inclined structure of which the caliber gradually increases towards the internal direction of the particle collecting and discharging chamber. According to the invention, blocking caused by unfavorable flotation of the cleaning particles is avoided and the structure is simple.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine drainage device and a washing machine. Background technique [0002] There is a closed environment between the inner and outer barrels of the existing washing machine, and only water can pass through. Due to the limitations of the above-mentioned structure of the washing machine and the particularity of the use environment, after 3-5 months of use, the outer wall of the inner barrel and the outer barrel Dirt will adhere to the inner wall, thereby breeding different degrees of bacteria, and most of the bacteria that grow are harmful to the human body. [0003] Along with the raising of people's living standard and the raising of the quality of life requirement, the solution of the hygienic problem of washing machine has shown very urgent. According to the investigation of the internal environment of the washing machine by relevant scientific research institutions...

AI Technical Summary

Problems solved by technology

[0006] But the structure of the washing machine mentioned above, after draining, because the rubber balls or flexible particles are in a state of free scattering in the barrel, a lot of noise will be generated during the high-speed dehydration process, and the energy consumption of the washing machine will be increased at the same time, which will affect the life of the washing machine.
