Whole, internally the position of outer barrel is adjusted immediately, it is ensured that interior outer barrel is maintained at horizontality；
3rd, the effectiveness in vibration suppression of outer barrel level adjustment system is formed in damping means and washing machine with structure described above
Synergistic effect, makes washing machine operational process more steady, further reduces the generation for even avoiding noise；And the damping means
The accuracy of adjustment can also be improved, and makes the adjusting of interior outer barrel level much sooner；
4th, four displacement sensors of the lower surface of control panel seat for being uniformly arranged on washing machine, make whether interior outer barrel deviates
The judgement of horizontality is sensitiveer, and smaller offset occurs immediately, can also detected, when four displacement sensors detect
Shift value when differing, i.e., outer barrel deviates from horizontality in explanation, at this point, displacement sensor is immediately to PLC chip (control
Device processed) it makes a response, PLC chip (controller), which only needs to be programmed using simple algorithm, can realize displacement signal
Conversion, to be relatively easy the accurate regulation and control that the signal control method of manipulation realizes internal outer barrel level.
The method that the present embodiment also provides outer barrel level adjustment system in a kind of washing machine described in application, including following step
Suddenly：
1) washing machine brings into operation, and the state of interior outer barrel changes, the inside and outside tubbiness state that displacement sensor will detect
Signal transmission is to PLC chip；
2) PLC chip acquires the displacement signal of each displacement sensor transmission, and displacement signal is handled；
3) PLC chip is by treated in step 2) displacement signal is converted to pressure signal, and by the pressure signal transmission
Give adjusting control device；

Advantageous effect described in two.
The method that the present embodiment also provides outer barrel level adjustment system in a kind of washing machine described in application, including following step
Suddenly：
1) washing machine brings into operation, and the state of interior outer barrel changes, the shape of interior outer barrel that displacement sensor will detect
State signal transmission is at controller；
2) controller acquires the displacement signal of each displacement sensor transmission, and judge each displacement sensor to outer barrel away from
From whether be corresponding setting fixed value；
3) by treated in step 2), displacement signal is converted to pressure signal to controller, and the pressure signal transmission is given
Adjusting control device；
4) adjusting control device adjusts air capacity inside damping means, the vibration damping intensity inside damping means by connecting pipe
Or damped coefficient changes, and changes so as to the active force of the internal outer barrel of damping means, makes displacement sensor to the distance of outer barrel
Restore to the fixed value of initial setting, interior outer barrel is made to restore to level run state.
Fixed value refers to each displacement sensor is arranged on babinet top, and interior outer barrel keeps horizontal equilibrium state
When, the initial distance of each displacement sensor to outer barrel.
Preferably, when the distance that the step 3) judges displacement sensor to outer barrel is not the fixed value of setting, to
Adjusting control device sends signal, and sends signal to adjusting control device.
The present embodiment also provides a kind of washing machine with outer barrel level adjustment system in the washing machine.The washing machine phase
There is following advantageous effect for washing machine of the prior art：
With can internal outer barrel level is adjusted immediately in washing machine operational process system, it can be ensured that inside and outside
Bucket remains level run state, makes entire laundry processes more steady, avoids the high vibration in laundry processes or shaking,
Noise is significantly reduced, improves user's use feeling.It avoids running at high speed or dehydration collides control-rod or casing of washing machine
The phenomenon that occur, contribute to extend washing machine service life.
It should be understood that the concrete numerical value included in specific embodiment listed above is only a kind of example, not
Limitation to technical solution of the present invention.
The above is only presently preferred embodiments of the present invention, not makees limitation in any form to the present invention, though
