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 components described in the description, and further comprises a throttling element arranged in a first chamber; the throttling element comprises a tube structure, part of which is inserted into a 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 a 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 with each 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...
