To dynamic balancing.
Further, it detects the dynamic equilibrium state of inner cylinder, calculates position and the active force for needing to carry out dynamic balancing compensation
Size, gradually the injection balance liquid into the counter balance pocket for needing injection balance liquid.By adjusting each counter balance pocket inner equilibrium liquid quality
Size realizes the Mass Distribution of adjustment inner cylinder, is rapidly achieved dynamic equilibrium state so as to adjust inner cylinder.
Further, in the injection balance liquid into specified counter balance pocket, while by air inlet discharge and equilibrium liquid volume
Identical air.
Further, during the dehydration process, the cleaning solution contained by the washings in inner cylinder is thrown away at a high speed, the matter of inner cylinder
Amount distribution changes again, and when the dynamic equilibrium state for detecting inner cylinder changes, calculating needs to be discharged the balance of equilibrium liquid
The position of chamber and the quality of equilibrium liquid are discharged the equilibrium liquid of the certain mass in corresponding counter balance pocket, remain at inner cylinder flat
Weighing apparatus state.
Further, when equilibrium liquid is discharged in specified counter balance pocket, while by air inlet sucking and equilibrium liquid volume phase
Same air.
As a preference, the water inlet is arranged in counter balance pocket far from inner cylinder axial location, is conducive to inject and arrange
Equilibrium liquid out.
As a preference, the air inlet is arranged in counter balance pocket close to inner cylinder axial location, is conducive to suck and arrange
Air out.
As a preference, the equilibrium liquid is water.
After adopting the above scheme, compared with the prior art, the invention has the following features:
Inner tank of washing machine automatic balancing arrangement and balance method proposed by the present invention, using on inner cylinder circumference different location it is flat
Weigh the intracavitary equilibrium liquid injected or certain mass is discharged, offsets the matter as caused by washings non-uniform mass in inner cylinder
Deviation is measured, makes inner cylinder during the dehydration process, dynamic equilibrium state can be rapidly achieved, and can remain inner cylinder dynamic balancing, with biography
System balance ring balance method compare, have fast response time, good balance effect, can on-line continuous accurately adjust inner cylinder dynamic balancing.

Specific embodiment
Further explanation is done to the present invention with specific example with reference to the accompanying drawing:
Embodiment 1
As shown in Figure 1, the present invention provides a kind of 1 automatic balancing arrangement of inner tank of washing machine, the balancing device includes in washing machine
Cylinder 1, counter balance pocket 2；The balancing device includes at least two counter balance pockets 2, and the angular separation such as each counter balance pocket 2 are fixed on the circle of inner cylinder 1
On post jamb face.
As a preference, as shown in Fig. 2, the counter balance pocket 2 is 1 inner surface of inner cylinder and existing washing machine lifting rib institute shape
At confined space, and be equipped with water inlet 3 and air inlet 4 in each counter balance pocket 2.
Further, as shown in Fig. 2, the water inlet 3 of the counter balance pocket 2 is far from 1 axial location of inner cylinder；The counter balance pocket
2 air inlet 4 is close to 1 axial location of inner cylinder.
For traditional balance method, this balancing device is by injecting certain mass in the counter balance pocket 2 to different location
Equilibrium liquid 5, the centrifugal force for generating the equilibrium liquid 5 in counter balance pocket 2 is with washings in inner cylinder 1 since Mass Distribution unevenness causes
Centrifugal force cancel out each other, so that inner cylinder 1 is rapidly achieved balance during the dehydration process.
As a preference, the equilibrium liquid 5 is water.
Embodiment 2
Based on above-mentioned apparatus, the present invention also provides the methods that inner tank of washing machine 1 balances, and this method is using adjustment liquid 5 each
The size of quality in counter balance pocket 2, makes inner tank of washing machine 1 in dewatering work, so that inner cylinder 1 is rapidly achieved dynamic equilibrium state, and protect
It holds inner cylinder 1 and remains dynamic balancing at work.In conjunction with Fig. 3, the specific steps are as follows:
S1, when washing machine dehydration procedure starts, inner cylinder 1 is started turning, and detection inner cylinder 1 is existed due to washings Mass Distribution unevenness
The centrifugal force generated during rotation, centrifugal force size and Orientation are F.
The equilibrium liquid 5 of injection certain mass in the counter balance pocket 2 of S2, Xiang Zhiding, since the equilibrium liquid 5 of injection has quality, institute
Can generate centrifugal force during rotation, centrifugal force size and Orientation is respectively F1、F2, by the parallelogram method of mechanics
Then it is found that F1And F2Resultant force F ' is generated, wherein the F and F ' size same direction is on the contrary, to offset since non-uniform mass produces
Raw imbalance.
S3, until dehydration terminates in dehydration carries out, cleaning solution contained by washings is constantly thrown out of in inner cylinder 1, is caused
Centrifugal force F originally can become smaller, and centrifugal force size and Orientation becomes f.
The equilibrium liquid 5 of certain mass is discharged, due to 5 mass of equilibrium liquid in counter balance pocket 2 in S4 in specified counter balance pocket 2
Reduce, so the centrifugal force that can be generated during rotation also becomes smaller, centrifugal force size and Orientation is respectively f1、f2, by mechanics
Parallelogram law it is found that f1And f2Resultant force f ' is generated, wherein the f and f ' size same direction is on the contrary, in remain
1 dynamic balancing during the dehydration process of cylinder.
In conclusion by above-mentioned technical proposal of the invention, by the way that one is injected or be discharged into different location counter balance pocket 2
The equilibrium liquid 5 for determining quality can adjust the Mass Distribution state of inner cylinder 1, improve the stability that inner cylinder 1 rotates, and reduce washing machine
Vibration and noise in operational process.
Thinking and method of the invention, there are many method and the approach for implementing the technical solution, and the above is only the present invention
Preferred embodiment, it is noted that for those skilled in the art, do not departing from the principle of the invention
Under the premise of, several improvements and modifications can also be made, these modifications and embellishments should also be considered as the scope of protection of the present invention.This implementation
The available prior art of each component part being not known in example is realized.
