Description
Technical field
The present invention relates to washing machine field, more particularly to a kind of clutch with magnetic rheologic liquid and this magnetic flow liquid clutch of setting
The washing machine of device.
Background technology
The structure of conventional washer be by interior bucket, outer barrel, agitating device (such as impeller), transmission system, control system and
Housing etc. is formed.During laundry, interior bucket does not rotate, and agitating device makees both forward and reverse directions rotation, drives inner bucket water and clothing to rotate and realize
Washing.The washing methods passes through practice test, and discovery has some defects：1st, only it is to be rotated by agitating device to produce water
Stream, washing form is single, cleans ratio and is difficult to improve.2nd, flow intensity is weak, and clothing is also easy to produce winding.In order to overcome drawbacks described above,
Some washing machine manufacturing enterprises design a kind of " turning barrel " washing machine, and its mode of washing is that interior bucket is in free state, stirring dress
When putting rotation, interior bucket rotates by reaction force caused by agitating device rotation, realizes that interior bucket reversely rotates with agitating device, from
And reach the purpose of " washboard ".But this method still suffers from deficiency, due to the unpowered drive of interior bucket, the rotation dynamics of interior bucket is small, and
For agitating device only in the rotating of interior bucket bottom surface, the effect of " washboard " is little, the unobvious that clean result improves, and still can not be very
Good solves the problems, such as clothing winding.In order to overcome drawbacks described above, a kind of washing machine of two-way washing is developed, the washing machine is
Interior bucket is configured with power drive mechanism, and during washing, interior bucket rotates in the opposite direction with agitating device under the drive of power, with
The purpose for improving " washboard " effect is realized, but if still using existing interior bucket and impeller structure on the washing machine, is then shown
Specific aim it is not strong, because impeller is located at bottom of the barrel, streams are single, and flow intensity seems very insufficient, it is difficult to is formed
Roll current, and clean result is difficult to higher, and the gap between interior bucket and impeller easily falls into foreign matter.
With the birth of two-power washing machine, above mentioned problem is readily solved, and traditional two-power washing machine is mostly using machinery
There is certain friction in formula clutch, mechanical clutch, there is frictional dissipation, there is the straight arrangement of clutch for driving washing machine in part in addition
It is electromagnetic clutch type, the mode for also having part washing machine to employ buoyancy clutch, interior bucket is suspended in outer barrel when entering water washing.With
The washing machine of upper several clutch modes, because of the limitation of its mechanical structure, can all take larger volume, and complicated, make
High price is expensive, fragile.Clutch is arranged between interior outer barrel, and the mechanical structure of big structure makes the space between interior outer barrel excessive,
Make the volume of the washing machine of identical washing amount excessive, meanwhile, frictional dissipation reduces the service life of washing machine.
New a kind of arrangement of clutch, it is only necessary to which clutch-plate on a small amount of magnetic flow liquid and impeller shafts realizes the effect of clutch
Fruit, magnetic flow liquid (Magneto rheological Fluid, abbreviation MR fluid) be by high magnetic permeability, low magnetic hysteresis it is small soft
Magnetic-particle, and non-magnetic liquid mix, and belong to controlled fluid, and the change of damping can be achieved, and have intensity height, viscosity
The features such as low, energy requirement is small, and temperature stability is good, in the presence of external magnetic field, can Millisecond moment by Newtonian liquid
Body becomes the higher Bingham plastic bodies or viscoelastic body of shear yield stress, and this transformation is continuous reversible.
The index that magnetic flow liquid meets has：
(1) zero magnetic field viscosity is low, to make it under magnetic fields, when having the growth of equal shear yield strength, has
Bigger adjustable extent.
(2) high-intensity magnetic field down cut yield strength is high, should at least reach 20~30Kpa, and this is to weigh magnetic flow liquid characteristic
One of leading indicator.
(3) impurity interference is small, to increase its use range.
(4) temperature use range is wide, i.e., has high stability in comparatively wide temperature range.
(5) fast response time, it is therefore desirable to reach Millisecond, so that MR fluid shock absorber is as active and semi- active control
During device, time lag problem is substantially not present.
(6) resistance to settling is good, and storage should be substantially not stratified for a long time.
(7) energy consumption is low, and larger shear yield strength can be produced under weaker magnetic field.
(8) nontoxic, non-volatile, free from extraneous odour, this is determined by its application field.
Clutch with magnetic rheologic liquid is divided into driving link and driven member, and the wherein drive plate of clutch is driving link, bell housing
Body is driven member, and drive plate is rotated with certain speed, when coil (i.e. magnet coil) no power, among housing and drive plate
Magnetic flow liquid keep its mobility, driven housing low speed rotation only under the effect of magnetic flow liquid viscous shear；When coil leads to
After electricity, magnetic field is produced in space, makes magnetic flow liquid that rheological effect occur, the ferromagnetic particle in magnetic flow liquid, which is magnetized, to be connected into
Chain, magnetic flow liquid become class solid, and this is, driving link and driven member simply by the presence of speed discrepancy it is necessary to shear these " iron chains ", because
And be driven and rise away from increase, housing speed, so as to serve the function of output rotating speed regulation.
The content of the invention
It is an object of the invention to provide distance between a kind of interior outer barrel is small, washing machine just can be driven respectively using clutch
The washing machine that impeller and interior bucket rotate.
Can be compact-sized it is a further object of the present invention to provide one kind, clutch abrasion is small, the good laundry of disengaging performance
Machine.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of washing machine that clutch with magnetic rheologic liquid is set,
Interior bucket, outer barrel and impeller including washing machine, the magnetic at least driving impeller to rotate is provided between the inner barrel and outer barrel of washing machine
Rheology fluid clutch.
The clutch with magnetic rheologic liquid include the line shaft of column, the cylindrical shape fixed cover being sheathed on line shaft and
It is arranged at the circular clutch-plate being fixedly connected inside fixed cover with line shaft.
The cavity full of magnetic flow liquid is provided with the fixed cover, the magnetic flow liquid surrounds clutch-plate.
Described clutch-plate is set on line shaft, line shaft driving clutch-plate rotatable movement in cavity.
It is provided with a pair opposite of positive electromagnet and negative electricity magnet of pole polarity outside the fixation, the positive electromagnet and negative
Cavity after electromagnet is powered where caused magnetic force line cutting magnetic flow liquid, positive electromagnet and negative electricity magnet are oppositely arranged.
The line shaft of the clutch with magnetic rheologic liquid is connected with the output shaft of the motor of washing machine, magnetic flow liquid from
When the electromagnet of clutch is not powered on, impeller rotation is operated alone.
The output end of the line shaft is connected with the input shaft of impeller, and fixed cover is connected with the input shaft of interior bucket, electricity
When magnet is powered, clutch with magnetic rheologic liquid driving impeller and interior bucket rotate simultaneously.
The control of the positive and negative magnet switching electricity of control on the power line and washing machine of the positive electromagnet and negative electricity magnet
Device is connected.
The positive electromagnet and negative electricity magnet are oppositely arranged on the both sides of cavity, parallel with the bottom surface of outer barrel in washing machine,
