Abstract

The invention relates to the technical field of washing machines, in particular to a shock absorber and a washing machine including the shock absorber. The invention aims to solve the problems of invariable damping force and poor damping effect of the shock absorber in the prior art. For this purpose, the shock absorber of the present invention comprises: a sleeve having a first chamber; a plunger having a second chamber slidably inserted into the In the first chamber; the shock absorber further includes a throttling member disposed in the first chamber, the throttling member includes a pipe structure partially inserted into the second chamber, and the pipe structure is Several damping holes are provided, and some of the several damping holes are opened / closed with the sliding of the plunger, and the first chamber and the second chamber are damped by the damping in the open state. The holes communicate with each other. The setting of the throttling member ensures that the damping force produced by the shock absorber of the present invention is variable at any time and has high stability, and can be popularized and used 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 the improvement of people's requirements for living comfort, the washing machine has become an indispensable household appliance in people's daily life. However, the washing machine can produce obvious vibration and noise during washing, rinsing and dehydration, which brings some inconvenience to people's normal life. [0003] On solving the problem of excessive vibration and noise when the washing machine works, the invention patent application with the publication number CN105986407A discloses a "shock absorber and washing machine, clothes dryer". Wherein, the shock absorber includes a sleeve with an open end and a first p...
