Description
Technical field
The present invention relates to washing machine field, especially a kind of balance device for washing machine and the laundry equipped with the balancing device
Machine.
Background technique
Present washing machine is to solve dehydration and vibration noise problem, generallys use fluid balance ring and offsets clothing bias.But
Fluid balance ring, which exists, resists the disadvantages of inclined ability is low, there are unstability sections and since processing technology causes leakage, liquid filled ratio to miss
The problems such as difference is big.Previous retrial balance ring uses the passive equilibrium loop system of steel ball and liquid combination form, to avoid taking off
The transient excitation problem of steel ball when water starts, full of the silicone oil with certain viscosity in steel ball cavity, to ensure starting moment
Steel ball revolving speed is close with interior bucket revolving speed.But with there is silicone oil leakage in this balance ring, once and leakage clothing will be caused
Secondary pollution.
In existing washing machine technology, washing machine is to solve dehydration and vibration noise problem, generallys use the counteracting of fluid balance ring
The eccentricity issues that interior bucket generates when rotating.But fluid balance ring there are anti-eccentric abilities it is poor, there are unstability sections the disadvantages of, and
Since processing technology leads to problems such as leakage, liquid filled ratio error big.
Application No. is 201120185597.3 Chinese patents to disclose a kind of ball balancing device of washing machine, including inside
Hollow toroidal shell is coaxially fixedly mounted on the turning barrel of washing machine；Multiple balanced balls are arranged inside toroidal shell,
And circumferentially moved inside toroidal shell, it is characterised in that: between being equipped between two adjacent balanced balls
Every the batching sphere of two balanced balls.A kind of ball balancing device of washing machine disclosed in the utility model, using full of circular casing
The direct collision of intracorporal equilibrium liquid and batching sphere barrier balanced ball in starting and high-speed rotation, is eliminated due to balanced ball collision
The noise of generation reduces influence of the noise to user, but due to being equipped with equilibrium liquid inside the balance ring, there are equilibrium liquid leakages
Problem, and once leakage will pollute clothing, not setting equilibrium liquid cannot only achieve the goal by batching sphere again, and batching sphere
There is also collisions between balanced ball.
A kind of washing machine is disclosed application No. is 201410742320.4 Chinese patent and for the ball balance of washing machine
Ring, comprising the rotatable bucket by motor driven, along the circular passage that is circumferentially with of bucket, channel is provided with and multiple can roll along channel
Dynamic sphere, multiple sphere is comprising Magnetic force ball and can be attracted by magnetic force non-magnetic ball.Due to there is the attraction of Magnetic force ball work
With multiple spheres, which can be drawn onto, is formed together a mass body, will not collide between the sphere of this mass body, or only
When the rotary motion of bucket is unstable, minority edge therein sphere collides, although this scheme reduces ball hits and produced
Raw noise, but it is formed together a mass body since balanced ball is drawn onto, the movement of the mass body is restricted, counterbalance effect meeting
It has a greatly reduced quality.
In view of this present invention is specifically proposed.
