Description
Technical field
The present invention relates to washing machine technology field, specifically washing machine vibration absorber, especially a kind of washing machine mutative damp vibration damping dress
Put and using the washing machine of the vibration absorber.
Background technology
Existing washing machine is divided into rotary drum washing machine and roller washing machine, and the structure of wherein pulsator washing machine includes：Formation is washed
The housing of clothing machine outward appearance；It is provided with the inside of housing and the outer barrel fixed and for accommodating washings is hung by supporting member；Can
It is rotatably mounted on the inside of outer barrel and its bottom is provided with the interior bucket of agitator；Installed in the downside of outer barrel and for producing
The motor of the driving force of agitator and interior bucket；For the driving force of motor to be selectively supplied into agitator and interior bucket
Power transmission；Drainage arrangement installed in the bottom of outer barrel and for discharging from the washings accommodated in outer barrel to outside, outward
Bucket is hung by derrick rig and is arranged on housing.
At present, derrick rig includes suspension rod, gooseneck bracket, ball seat, spring and spring base, and gooseneck bracket is arranged on suspension rod top, bullet
Spring abutment, spring and ball seat are extended upward through on suspension rod successively by the bottom of suspension rod, and friction plate is cased with ball seat；On washing machine shell
Spherical groove is provided with, convex spherical and the spherical groove on housing of gooseneck bracket coordinate；The bottom of outer barrel also has spherical groove,
The convex spherical of ball seat coordinates with the spherical groove of outer barrel bottom, so as to inner barrel and outer barrel is suspended on washing machine shell.
Washing machine makes the vibration that outer barrel is produced ball seat can be caused to move up and down when working, ball seat and then by telescopic spring, friction plate
Damping force is produced with suspension rod reciprocating friction, so as to suppress vibration, the purpose for improving complete machine oscillation noise level is reached.
But, spring just loses damping effect after compressing completely, thus in washing of drum type washing machine and dehydration, suspension rod can not be fine
Play damping effect, cause vibration of washing machine big and displacement be big.In dehydration transient phases, built-in system vibration is larger,
Need derrick rig to provide relatively large damping force to suppress built-in system vibration；In dehydration steady-state process, built-in system vibration
It is smaller, then need derrick rig to provide relatively small damping force to isolate vibration；And above-mentioned derrick rig is only capable of by friction plate
Single damping force is provided, and during derrick rig assembling, ball holder surface understands grease to improve lubricating condition；So internally system
The larger dehydration transient phases of vibration, the damping force of derrick rig can often be difficult to the operating vibration of suppression system；Internally system
Less dehydration steady-state process is vibrated, under viscous effect and suspension rod the damping force effect of grease, can cause derrick rig upper and lower again
, there is abnormal vibration noise problem in play.
In view of this it is special, propose the present invention.
