A kind of washing methods, the driving mechanism that is used for this method and washing machine thereof
Technical field
What the present invention relates to is a kind of driving mechanism, and adopts the washing machine of this driving mechanism and the washing methods that utilizes described driving mechanism and washing machine to wash.Specifically, the present invention relates to a kind of driving mechanism and washing machine and method that washing machine also can start impeller and the rotating simultaneously of interior bucket that be used for.
Background technology
The washing machine that prior art discloses a lot " impeller (axle) and interior bucket (axle) backward rotation ", below just wherein three kinds of typical examples describe, by understanding and compare the content of these prior aries, can know more and understand purpose of the present invention, specific as follows:
KR89-13336, a kind of washing machine is disclosed, concrete is interior bucket rotation, the internal gear of the lower end of interior bucket drives 3 star gear trains and rotates in the same way, the external tooth engagement of 3 star gear trains and impeller bottom also sends power to impeller and makes it backward rotation, if idle running, the rotating ratio between interior bucket (axle) and the impeller (axle) is substantially invariable; When impeller is subjected to resistance, for example, the resistance that the pressure of water (influencing less), especially clothing form impeller, at this moment, the rotating ratio between interior bucket (axle) and the impeller (axle) be according to water yield size and/or clothing how much the change in resistance of formation change.
CN94118550, a kind of " electric washer " disclosed, the not only rotor rotation of described washing machine, sink also is configured to rotate freely, concrete is the power shaft rotation, by gear train power is delivered to interior bucket axle and impeller axle, if idle running, the rotating ratio between interior bucket (axle) and the impeller (axle) is substantially invariable; When adopting this scheme, no matter impeller still in bucket be subjected to resistance, for example, the resistance that the pressure of water and clothing form, at this moment, the rotating ratio between interior bucket (axle) and the impeller (axle) be according to water yield size and/or clothing how much the change in resistance of formation change.
US3216227, this documents discloses and a kind of interior bucket axle and impeller axle has been separately fixed on the stator and rotor of motor, the impeller of described washing machine and the interior barrel-shaped reverse rotation that becomes, equally, when impeller and/or interior bucket are subjected to resistance, the rotating ratio between interior bucket (axle) and the impeller (axle) also with water yield size and/or clothing how much the change in resistance of formation change.
Above-mentioned three typical schemes have a common characteristic, that is, during actual the use, the rotating ratio between interior bucket (axle) and the impeller (axle) changes with water yield size and/or clothing; The impeller axle begins to rotate to end to a direction, and its rotating ratio also changes, and is uncertain in other words conj.or perhaps; Therefore, " the rubbing " that forms between interior bucket and the impeller also is uncertain; Because it is inconsistent to be applied in the positive and negative revolving force (winding process) of washing clothes, therefore just can not farthest reduce winding.
In view of this, the present invention is proposed.
Summary of the invention
Main purpose of the present invention is to provide a kind of impeller that is used for washing machine and can makes washing machine barrel-shapedly to become rotating to get driving mechanism with interior.
Another object of the present invention provides a kind of impeller and interior bucket that is used to adopt the washing machine of described driving mechanism and can make washing machine and form rotating when washing.
A further object of the present invention provides a kind of that be used to adopt described washing machine and can make clothing by the positive and negative washing methods of rubbing.
For the difference of clear and definite the present invention and prior art, researcher of the present invention has carried out as giving a definition:
" wash cycle cycle ", be meant, no matter detergent water washs or carry out rinsing with clear water with containing, and one " wash cycle cycle " comprises, impeller begins to a direction rotation, interior bucket begins reverse rotation simultaneously, the rotating speed of impeller and interior bucket is by zero → maximum → zero, and impeller is to another direction rotation then, and interior bucket also changes the direction rotation simultaneously, the rotating speed of impeller and interior bucket is by zero → maximum → zero, and this complete procedure is defined as " wash cycle cycle " in the present invention;
" on-fixed rotating ratio ", on-fixed rotating ratio of the present invention is meant, in " wash cycle cycle ", the water yield and clothes weight are fixed, the rotating speed of impeller is by zero → maximum → zero, the rotating speed of bucket was also from zero → maximum → zero in reaction force made, and interior bucket is because after being subjected to factor affecting such as frictional resistance, inertia, the rotating ratio of each rotation moment impeller and interior bucket is all different.
" fixed rotating speed ratio ", fixed rotating speed ratio of the present invention is meant, in " wash cycle cycle ", the water yield and clothes weight are fixed, the rotating speed of impeller is by zero → maximum → zero, reverse actuating force makes interior barrel rotating speed also from zero → maximum → zero, and interior barrel is not subjected to factor affecting such as frictional resistance, inertia, and each rotation moment impeller is all the same with the rotating ratio of interior bucket.
" rotating " is meant, in washing machine washing or rinse cycle, impeller (axle) and interior bucket (axle) are pressed the opposite direction rotation simultaneously.
" gear-box " is meant, a cylindrical box is fixed with loam cake and lower cover, and the upper and lower covers center is provided with axis hole, in the gear-box gear train can be set, gear shape for example,
Knucle-gear, cylindrical gear, bevel gear and worm screw, the example of gear train is the fixed shaft gear train that does not have internal gear on the inwall of described gear-box, or, contain, do not contain the differential gear train of internal gear or ring gear in the gear that the gear train in the gear-box relates to.
