Shock absorber and clothing treating apparatus comprising same

Abstract

The invention relates to the technical field of washing machines, in particular to a shock absorber and a washing machine comprising same. The invention aims at solving the problems that in the priorart, the damping force of the shock absorber can not be changed, the damping effect of the shock absorber is poor, and the like. In order to realize the aim, the shock absorber comprises a sleeve anda plunger piston, wherein the sleeve is provided with a first chamber, and the plunger piston is provided with a second chamber and can be inserted into the first chamber in a sliding way; the shock absorber is characterized by further comprising a throttling element arranged in the first chamber; the throttling element comprises a tube structure, part of which is inserted into the second chamber;a plurality of first damping holes are formed in the tube wall of the tube structure; a sealing structure is arranged between the outer wall of the tube structure and the inner wall of the plunger piston; one parts of the plurality of first damping holes are in an open / a closed state as the plunger piston slides, so that the first chamber and the second chamber are enabled to be communicated witheach other by means of the first damping holes which are in the open state. The damping force of the shock absorber provided by the invention can be changed at any time, and the shock absorber is high in stability.

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 the improvement of people's requirements for living comfort, the washing machine has become one of the indispensable household appliances in people's daily life. However, the washing machine will produce obvious vibration and noise during the washing and dehydration process, which affects the user experience to a certain extent. [0003] In order to solve the problem that the washing machine produces obvious vibration and noise during the washing and dehydration process, the invention patent application with the publication number CN105986407A discloses a "shock absorber, washing machine, and clothes dryer". Wherein, the sho...

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 problem that the existing shock absorber is prone to failure due to poor vibration damping effect and wear of the friction ring during the working process of washing and dehydration, the present invention provides A shock absorber is provided, which comprises: a sleeve having a first chamber; a plunger having a second chamber slidably inserted into the first chamber; the shock absorber also includes a throttling member disposed in the first chamber, the throttling member includes a pipe structure partially inserted into the second chamber, the The pipe wall of the pipe structure is provided with several first damping holes, and a movable sealing structure is provided between the outer wall of the pipe structure and the inner wall of the plunger, and a part of the several first damping holes is The sliding of the plunger is in an open / closed state so that the first chamber and the second chamber communicate with each other via the first orifice in an open state
