Further include squeezer structure (not shown in detail), squeezer structure is arranged in longitudinal balance room 120, and dynamic poise device 100 with
When inner cylinder rotor rotates, outward normal direction 220 is moved to squeeze the equilibrium liquid 130 in axial cavity, makes equilibrium liquid 130 certainly
Axial cavity is flowed to radial chamber.
As an embodiment, squeezer structure including pressure water-bound 121 and branch bulging water-bound as shown in figure 4, stretch
Shrinking structure 122 presses water-bound 121 that can drive equilibrium liquid to realize equilibrium liquid in radial equilibrium room under the action of rotary centrifugal force
It is moved axially between 110 and longitudinal balance room 120.The pressure water-bound 121 can be plate, or in normal side
Structure such as square, cube, ship shape etc. with thickness upwards, as long as equilibrium liquid can be squeezed to radial equilibrium room.
Stretching structure 122 can be spring or any other structure with retractility.
Wherein, as an example, the equilibrium liquid 130 in dynamic poise device 100 follows inner cylinder rotor in dynamic poise device 100
When high speed rotation is for example dehydrated rotation, outer surface of the water-bound 121 in dynamic poise device 100 radially is preferably more than pressed.
The application can realize the dynamic of inner cylinder critical rotor speed during laundry machine dehydration by the axial movement of equilibrium liquid
State is adjusted, and so that inner cylinder rotor is remained at the safe speed of rotation operation for deviateing critical speed area, is reduced inner tank of washing machine rotor
The risk of resonance, while equilibrium liquid axial movement can also balance the barycenter caused by clothing unbalance loading moves forward and move forward well, centainly
Inner cylinder wobble amplitude is reduced in degree, improves operation stability.
It, also can be in balancing device inner radial relative motion, when clothing is inclined while equilibrium liquid moves axially in the application
When load causes the big swing of inner cylinder rotor, the equilibrium liquid dynamic in radial equilibrium room moves to the relative direction of clothing unbalance loading, from
And realize the radial equilibrium of inner cylinder rotor, reduce oscillation crosswise caused by clothing unbalance loading, reduces stress at bearing block.

As shown in figure 5, the structure is supported by two bearings 410 and 420, it is preferable that bearing 410 is small bearing, and bearing 420 is
Big bearing plays supporting role with preferably countershaft 300.The weight that inner cylinder rotor is born is concentrated mainly on the cantilever of shafting
End, resonance critical speed when which rotates are represented by：
In formula：
ncFor critical rotor speed；
π is pi；
E is the elasticity modulus of shaft material；
I is the cross sectional moment of inertia of axis；
M is the equivalent mass of shafting；
L is shafting equivalent length；
λ is the ratio of the equivalent barycenter of the shafting distance away from bearing support B and shafting equivalent length L.
By critical Speed Calculation formula it is found that after inner tank of washing machine rotor structure and clothes weight determine, influence interior
The factor of cylinder rotor resonance critical speed comes from λ, i.e., can realize that critical rotor turns by adjusting the centroid position of equivalent mass
The adjusting of speed.
The application is based on principles above, the axial movement of equivalent mass barycenter can be realized using dynamic poise device 100, and right
Critical rotor speed dynamic regulation.
Fig. 6 shows that a preferred implementation of longitudinal balance schematic diagram is realized in the longitudinal balance room of the dynamic poise device of the application
The schematic diagram of example.
As shown in fig. 6, after washing machine enters high speed rotation such as dehydration mode, inner cylinder rotor speed rises, axial flat
Pressure water-bound 121 in weighing apparatus room by centrifugation force effect due to that can be drawn stretching structure 122 and outside normal orientation movement, simultaneously
Stretching structure 122 can have reversed pulling force F to pressure water-bound 1211=k Δs x and F2=k Δ x, wherein：
K is the rigidity of telescoping mechanism,
Δ x is the outer normal direction move distance of water squeezing plate,
And each rotary regimes pressure water-bound 121 has Fr=F1+F2Stress balance, when washing machine speed dynamic changes,
FrAlso can dynamic change, corresponding Δ x also can dynamic change, pressure water-bound 121 i.e. can in the case of rotation speed change outside normal direction
Dynamic displacement simultaneously squeezes equilibrium liquid 130, and equilibrium liquid 130, which is squeezed, to be moved from longitudinal balance room 120 to radial equilibrium room 110,
131 liquid flow path direction for showing equilibrium liquid in figure, to which the equivalent barycenter of entire inner cylinder rotor can be changed in axial position, i.e.,
The resonance critical speed dynamic regulation effect that inner cylinder rotor is realized by dynamic regulation value, can effectively avoid washing machine and operates in
The risk in the critical speed that resonates area, and by washing machine raising speed, 130 axis of equilibrium liquid moves back, and can reduce rotor cross to a certain extent
To the amplitude of vibration, operation stability is promoted.
Fig. 7 shows the dynamic equilibrium flow schematic diagram of a preferred embodiment of the dynamic poise device of the application.
As previously mentioned, while realizing rotor axial balance during laundry machine dehydration, the balance in radial equilibrium room
Liquid, which also will appear, diametrically to be moved, i.e., when clothing unbalance loading is run to cylinder lower end, equilibrium liquid can move to diameter under effect of inertia
To the top of balance cylinder, and can be stored in the liquid storage cylinder on top, on the contrary, when running to cylinder upper end such as clothing unbalance loading, equilibrium liquid
Also the lower part of radial equilibrium room can be moved under effect of inertia and is stored in liquid storage cylinder, it is flat in this way in radial equilibrium room
Weighing apparatus liquid always moves to the opposition position of unbalance loading clothing, is opposed by this unbalance loading, you can realizes and balance ring is arranged with cylinder front end
