Shock absorber and washing machine comprising shock absorber

Abstract

The invention relates to the technical field of washing machines, in particular to a shock absorber and a washing machine comprising the shock absorber. The shock absorber aims at solving the problemsthat the damping force of a shock absorber in the prior art is not variable, and the shock absorption effect is poor due to the failure of the shock absorber. In order to achieve the purpose, the shock absorber comprises a sleeve and a plunger, wherein the sleeve is provided with a first cavity; the plunger is provided with a second cavity, and the plunger is slidably inserted into the first cavity; a throttling element is further arranged in the first cavity, and a plurality of damping holes are formed in the throttling element; one part of the damping holes are in an open / closed state alongwith sliding of the plunger, and the first cavity and the second cavity are communicated with each other by using the damping holes in the open state. Through the arrangement of the throttling element, a part of the damping holes are in the open / closed state along with sliding of the plunger, so that the shock absorber is variable in damping force and can be used and popularized on a large scale.

Description

technical field [0001] The invention relates to the technical field of clothes treatment, in particular to a shock absorber and a clothes treatment device including the shock absorber. Background technique [0002] The washing machine is a clean electrical appliance that uses electric energy to wash clothes. With the acceleration of the pace of life and people's high requirements for living comfort, the washing machine has become an indispensable household appliance in people's daily life. However, the washing machine can make a lot of vibration and noise during washing, rinsing and dehydration, which brings some inconvenience to people's normal life. [0003] To solve the problem of excessive vibration and noise when the washing machine is in operation, a utility model patent application with the publication number CN201310034Y discloses a "drum washing machine shock absorber". Specifically, the shock absorber of the drum washing machine includes a guide damping cylinder, ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problems that the damping force of the existing shock absorber is not variable during the working process, and the wear of the friction ring easily leads to the failure of the shock absorber, the present invention provides a shock absorber , comprising a sleeve having a first chamber; a plunger having a second chamber slidably inserted into the first chamber; the first A throttling piece is also arranged in the chamber, and the throttling piece is provided with several damping holes, and a part of the several damping holes is in an open / closed state with the sliding of the plunger, and the first chamber and the second chamber communicate with each other via the open orifice
