Description
【Technical field】
The present invention relates to washing machine and the balanced controls of washing machine.
【Background technology】
Washing machine generally has the bucket that can drive by motor and rotate.Clothing is washed and dehydrating operations in bucket.
In order that bucket tends to balance in rotary course, so that the produced vibration of the uneven rotation for reducing bucket and noise,
Gimbal can be circumferentially installed on bucket.Gimbal generally comprises the housing with annular cavity, can be moved in ring inner chamber body
Dynamic spheroid, and the viscous liquid with certain lubrication and offer viscous force.
In the water smoking, because the rotating speed of bucket is higher, the phase of spheroid automatic stabilisation in gimbal in clothes eccentric mass
Opposition position, so as to offset the eccentric mass that clothes is formed.
However, when the capacity of the viscous liquid in gimbal is that the requirement for meeting the water smoking fills excessive, at relatively low turn
The washing stage of speed, spheroid can be rotated in the presence of viscous force and gravity around ring.By after the minimum point of ring,
Spheroid slows down and rises.Now, due to there is speed difference between spheroid, it may occur that collision, so as to produce noise.
【The content of the invention】
It is an object of the present invention to provide a kind of improved gimbal for washing machine, balance in washing process is reduced
The impact noise of spheroid in ring.
For object above, the technical solution adopted by the present invention is：A kind of gimbal for washing machine, comprising having
The spheroid that can be rolled along annular cavity with viscous fluid and multiple in the housing of annular cavity, annular cavity.Annular
Inner chamber is provided with liquid holding meanss near the side of central shaft.The liquid holding meanss are configured to when gimbal is static
Or around central shaft to be rotated less than the first rotating speed when viscous fluid is absorbed from annular cavity or viscous fluid is kept it
In, when gimbal around central shaft to be rotated more than the second rotating speed when discharge viscous fluid therein.
Use the gimbal of above-mentioned technical proposal static or around central shaft to be rotated less than the first rotating speed when, viscous fluid quilt
Liquid holding meanss are absorbed, and are kept wherein.Then the viscous fluid in annular cavity is reduced, and it acts on spheroid
On viscous force then reduce so that spheroid can rest on the lower position of annular cavity without being forced past in annular
The peak in chamber, so as to prevent spheroid from mutually colliding generation noise.On the other hand, when gimbal around central shaft being more than
When second rotating speed rotates, under the influence of centrifugal force, liquid holding meanss discharge viscous fluid therein to toroidal cavity
In.Viscous fluid in toroidal cavity then increases, and its viscous force acted on spheroid increases, and promotes spheroid in ring
Detoured in shape cavity, and reach balance quickly.Meanwhile, now more viscous fluid can quickly absorb spheroid phase
For the motion energy of ring, the noise that spheroid mutually collides generation is eliminated.
Used as one of implementation method, liquid holding meanss are comprising liquid containing chamber and in the cavity wall in liquid containing chamber
The opening of annular cavity is connected, so as to allow the viscous fluid to enter liquid containing chamber or from liquid containing chamber from opening
Into annular cavity.
Used as one of implementation method, opening is located at side of the liquid containing chamber away from the central shaft of annular cavity.Such one
Come, viscous fluid is more easily by opening.
Used as one of implementation method, it is the aperture or narrow slit of multiple dense distributions, the wherein size of aperture or narrow slit to be open
Be designed to when gimbal is static or around central shaft to be rotated less than the first rotating speed when allow the viscous fluid from annular
Pass through the aperture in chamber or narrow slit enters liquid containing chamber and keeps wherein, when gimbal around central shaft with more than second
Rotating speed allows the viscous fluid to enter annular cavity from liquid containing chamber when rotating.The size of aperture or narrow slit and viscosity
The surface tension coefficient of fluid is related.Viscous fluid is at least allowed to be flowed out not from aperture or narrow slit under static state.
When gimbal is static or around central shaft to be rotated less than the first rotating speed when, be located at least in the viscous fluid of lower position
Due to larger pressure, being squeezed through opening, into liquid containing chamber.When gimbal around central shaft with more than
When two rotating speeds rotate, viscous fluid is subject to larger centrifugal action and passes through opening, and annular is entered from liquid containing chamber
Inner chamber.
Used as one of implementation method, liquid holding meanss inhale structure comprising porous hair.Porous hair inhale structure be easy to receive and
Viscous fluid is kept, and with very strong carrying capacity.
Used as one of implementation method, liquid holding meanss are made up of sponge or perforated foams.
As one of implementation method, highest washing rotating speed of first rotating speed less than or equal to washing machine.The washing rotating speed is included
Master washes the rotating speed in stage and the rotating speed of rinse stage.Then, when gimbal is loaded on washing machine and in washing machine operation
During washing course, liquid holding meanss absorb viscous fluid from annular cavity or keep wherein viscous fluid, so that
Ensure that in washing course spheroid rests on the lower position of annular cavity without being forced past the highest of annular cavity
Point, so as to prevent spheroid from mutually colliding generation noise.Wherein washing course washes process and rinsing stroke comprising master.
Used as one of implementation method, the second rotating speed washs rotating speed more than the highest of washing machine, minimum de- less than washing machine
Water rotating speed.The washing rotating speed washes the rotating speed in stage and the rotating speed of rinse stage comprising master.Minimum dehydrating speed refers to washing machine
Minimum dehydrating speed in default multiple dehydrating speeds.Then, when gimbal is loaded on washing machine and in washing machine
During operation washing course, viscous fluid will not flow out from liquid holding meanss.Wherein washing course washes process comprising master
And rinsing stroke.And when washing machine runs dehydration process, viscous fluid will be from liquid before reaching minimum dehydrating speed
It is gradually released in annular cavity in holding meanss.More viscous fluid promotes spheroid to be detoured in toroidal cavity, and
Balance is reached quickly.Meanwhile, now more viscous fluid can quickly absorb motion energy of the spheroid relative to ring,
Eliminate the noise that spheroid mutually collides generation.
Present invention also offers a kind of washing machine, it includes and is driven and rotatable bucket by motor, and bucket is circumferentially with
The gimbal stated.
Preferably, the rotating shaft of bucket is horizontally or diagonally set.
The present invention is conducted further description below in conjunction with accompanying drawing.
