Problems solved by technology
[0004] The existing shock absorber can have a better shock absorption effect in the case of small amplitude in the high-speed dehydration stage, but the shock absorption effect is not ideal in the large-amplitude conditions such as washing, rinsing, and low-speed dehydration stages.

The invention belongs to the field of washing machines, and specifically discloses a washing machine shock absorber, which includes a sleeve and a piston inserted into the sleeve at one end, a sliding part is arranged in the sleeve, and a first friction is arranged between the sleeve and the piston. A second friction member is provided between the sleeve and the sliding member, and an elastic supporting part is also provided between the sliding member and the sleeve. When the piston moves relative to the sleeve, the elastic supporting part is in contact with the first friction member and / or Or the second friction member cooperates to absorb the shock transmitted to the sleeve or the sliding member. The invention also discloses a washing machine with the shock absorber. The shock absorber of the present invention is not only suitable for washing, rinsing, low-speed dehydration and other large-amplitude working conditions of the washing machine, but also suitable for small-amplitude working conditions during high-speed dehydration, thereby achieving better shock and noise reduction effects.
Description
technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a washing machine shock absorber and a washing machine. Background technique [0002] From the point of view of the entire washing process of the washing machine, vibrations are generated in all stages of washing, rinsing, and dehydration. The rotation speed of the inner tub of the drum washing machine is from 0 to 1460r / min, that is, the rotation speed changes from 0-25Hz. During the rotation of the inner tub, due to the uneven distribution of laundry, two forces in the vibration system are formed. One is the eccentric load that causes the outer The cylinder moves up and down; the centrifugal force causes the outer cylinder to shake from side to side. The shock absorber of the existing washing machine mainly relies on friction to buffer and consume the vibration energy during washing and dehydration of the washing machine. In the drum washing machine, the shock abso...
