Description

A kind of washing machine drive system and washing machine
Technical field
The present invention relates to washing machine field, and in particular to a kind of washing machine drive system, the invention further relates to the driving The washing machine of system application, is particularly suitable for application to the low and middle-grade washing machine fields that vast family uses.
Background technology
The groundwork of washing machine is rotated by drive mechanism driving impeller, and agitation current and clothing are rotated, and reach washing The purpose of clothing.The power source of conventional drive mechanism is motor at present, and torque when motor is rotated by the output shaft of motor is passed Deceleration device is passed, then the output shaft of deceleration device is connected with impeller, so as to drive impeller to rotate.
The rotating speed of common electric machine is higher, in order to obtain suitable output speed, in actual applications, it is necessary to be carried out to motor Slow down, conventional mode, which has, to be made motor be delivered to decelerator by one-level belt pulley to slow down, one-level or many is set in decelerator Level mechanical reduction gear completes the deceleration of a constant-speed ratio.This structure is not only complicated, and space-consuming is big.In order to solve this skill Art problem, has some on removing belt pulley, motor is directly connected to decelerator at present, due to its motor body and Decelerator is still relatively independent, and motor body respectively needs to take installing space with decelerator, and structure is not compact enough, body Product is still larger.
Therefore, the driving mechanism for washing machine for how to design a kind of compact conformation, occupying little space, is those skilled in the art The technical issues that need to address.
In order to solve the above-mentioned technical problem, with reference to the applicant in the development Experience for many years of this area, the applicant is first Applied for multinomial patent, such as Publication No. CN102677427A discloses a kind of washing machine driver, including motor, wash shaft, Dehydration axle sleeve and gear reduction in the wash shaft are sleeved on, the wash shaft is coaxially installed on the motor of the motor Internal rotor and affixed with the output gear of the gear reduction, the input gear axle of the gear reduction is plugged in In the axis hole of the rotor.Due to the input gear axle of gear reduction is inserted into the axis hole of rotor, make Rotor effectively becomes one gear reduction and motor as the tooth rest of gear reduction, so as to subtract The small axial dimension of washing machine driver so that the washing machine driver it is simple and compact for structure, occupy little space.And for example award Power Publication No. CN103422326B Chinese invention patent discloses a kind of drive unit of washing machine, and it includes:For providing Rotational kinetic energy without rotating shaft rotary body;Speed change gear on the rotary body, for being obtained from rotary body center position Rotational kinetic energy is taken, and exports the power that its rotating speed is equal to or less than the rotary body rotating speed;Connect the washing of the speed change gear Axle and dehydration axle sleeve, will be described dynamic equal to or less than the rotary body rotating speed in the presence of the speed change gear exports power Power is respectively supplied to washing and the dehydration execution unit of washing machine;Wherein, dehydration axle sleeve is sheathed on outside wash shaft and rotated with it Connection, the drive unit of washing machine of the invention, speed change gear is arranged on a rotating body for providing rotational kinetic energy, therefore compression by it The volume of whole drive device, and it is simple in construction, compact, the energy is saved, noise is small.
For another example the Publication No. CN103437126A of the applicant's earlier application Chinese invention patent discloses one kind and washed Clothing machine drive mechanism and washing machine, including motor, the transmission component being connected with motor, clutch component and installation housing, Clutch component includes clutch gear ring and the solenoid mechanism outside clutch gear ring;Installing housing includes stator mounting disc And installing plate, planetary gear train is located in the train cavity that is fixedly connected to form of stator mounting disc and installing plate, and clutch component is located at Stator mounting disc and motor are connected in the motor chamber to be formed, wherein, clutch gear ring is axially slidably socketed in drive shaft Put and be connected together or depart from rotor assembly, and it after rotor assembly disengaging with being in transitory state;Reach it is simple in construction, Compact, small volume purpose.
In summary, these earlier applications of the applicant relative to prior art between gear reduction and motor The volume occupancy of connection and the breakthrough for bringing change formula on compact conformation degree for washing machine driving field, but the applicant These earlier applications be use by gear or electromagnetic clutch mechanism integral installation in motor, it is pre- that this is accomplished by motor Larger installing space is stayed, not only results in that motor size is big, consumptive material is more, manufacturing cost is high, and motor is in design, manufacture view There are more highly difficult, the unsuitable low and middle-grade washing machine fields used applied to vast family.
And Authorization Notice No. discloses a kind of brushless electric machine direct drive for CN2443980Y Chinese utility model patent Decelerating clutch of washing machine, the biography square of Clutch input shaft is directly coaxially mounted to using permanent-magnetic outer rotor brshless DC motor On axle sleeve, and it is fixed on clutch housing, brushless electric machine axle is clutch torque transmissioning shaft again;The technology elimination pulley drive, So that clutch is more minimized.But because the technology uses permanent-magnetic outer rotor brshless DC motor, motor cost is high, and adopts The attachment structure of clutch and rotor is cumbersome, while the independence of driving lever and brake arm is respectively adopted in clutch and arrestment mechanism Structure, the connection member of use is more, and connection is complicated, and cost is high, and structure is not compact enough, same unsuitable applied to vast family The low and middle-grade washing machine fields used.
Accordingly, it would be desirable to seek a kind of washing machine drive system, both meeting simple and compact for structure, the condition occupied little space Under, while cost is low, connection member is few, and manufacturing process is simple.
