Description
Technical field
The present invention relates to a kind of damper, particularly a kind of with motor damping changing impact damper and the washing machine of this damper is housed.
Background technology
Existing tumbling-box washing machine comprises the shell that forms outward appearance; Be arranged on the wash bucket that is used to deposit slurry in this shell; Be arranged in this wash bucket and be used for clothing is washed the cylinder with dehydrating operations with rotatable mode; Be arranged on the back of this wash bucket and be connected in the drive motors of the rotating shaft of cylinder.Can be rotatably set in the front surface of shell through its door that clothing is put into or taken out, and the support that is used for the rotating shaft of back-up roller is arranged on the back of wash bucket.Spring is fixed on shell on the top of wash bucket, and the damper that is delivered to the vibration of wash bucket by cylinder of being used to decay is arranged on the bottom of wash bucket.
Fig. 1 is the longitudinal sectional view that illustrates according to the damper of the tumbling-box washing machine of prior art.As shown in the figure, existing damper 20 comprises the cylinder 21 that is fixed on shell 11 and has holding portion 21a; Be fixed in wash bucket 12 and be arranged to insert the holding portion 21a of this cylinder 21 or from its rod-like element of separating 22; And be connected in the external peripheral surface of this rod-like element 22 and the damping piece 23 that contacts with the friction surface 21b of this cylinder 21.
