The tension spring 210 of body 100, so that outer cylinder 200 is hung inside cabinet 100.Inner cylinder is coaxially disposed within 200 inside of outer cylinder, matches
Being set to can be rotatable around its axis.Above-mentioned washing machine still further comprises the driving device of driving inner cylinder rotation.Tumbling-box washing machine
Internal specific structure be it is well known to those skilled in the art, be not discussed here.Damping device 300 is fixedly installed on outer
The bottom plate 301 of the top of cylinder 200, the first pedestal 310 and the second pedestal 320 is fixedly connected with the roof of outer cylinder 200.
In general, the top of washing machine outer cylinder 200 is arcwall face, it is unfavorable for the installation of damping device 300.In the present embodiment
In, in order to make damping device 300 be set to 200 top of outer cylinder strongerly, it is fixed one can be added at the top of outer cylinder 200
Plate 220.The upper surface of the fixed plate 220 is horizontally disposed, and lower surface is arcwall face, to cooperate 200 upper surface of outer cylinder.First base
The bottom plate 301 of seat 310 and the second pedestal 320 is connect by fastening screw with the upper surface of fixed plate 220.
In the present embodiment, the working principle of damping device 300 are as follows: when washing machine work, inner cylinder rolls in outer cylinder 200
Dynamic, outer cylinder 200 will generate vibration.Outer cylinder 200 will drive 330 oscillation crosswise of vibrating body of damping device 300, since there are springs
With damped part 360, the vibration frequency of vibrating body 330 and outer cylinder 200 is not identical, that is to say, that the asynchronous vibration in the same direction of the two
It is dynamic.Therefore, some reversals of vibrations that vibrating body 330 occurs can offset the vibration of outer cylinder 200 to a certain extent, especially outer
The oscillation crosswise of cylinder 200.It is analyzed from energy point of view, kinetic energy a part of outer cylinder 200 passes to vibrating body 330, outer cylinder 200 itself
Kinetic energy reduce, Oscillation Amplitude reduce.During vibrating body 330 vibrates, it is dynamic that damped part 360 will consume its vibration
Can, convert kinetic energy into interior energy.Therefore, the kinetic energy of outer cylinder 200 will be consumed persistently, so that its Oscillation Amplitude will be obviously reduced.
In addition, the oscillation crosswise that outer cylinder 200 can be more efficiently absorbed is dynamic since vibrating body 330 is along washing machine oscillation crosswise
Can, this effect is that washing machine in the prior art cannot achieve.
It will be understood by those skilled in the art that in case of no particular description, so-called "upper" in the embodiment of the present invention,
"lower", "left", "right", "front", "rear", " cross ", " perpendicular " etc. be used to indicate the term of orientation or positional relationship be with washing machine or
For on the basis of the real use state of damping device 300, these terms are merely for convenience of describing and understanding of the invention
Technical solution, rather than the device or component of indication or suggestion meaning must have a particular orientation, therefore should not be understood as pair
Limitation of the invention.
So far, although those skilled in the art will appreciate that present invention has been shown and described in detail herein multiple shows
Example property embodiment still without departing from the spirit and scope of the present invention, still can according to the present disclosure directly
