WASHING METHOD OF WASHING MACHINE AND WASHING MACHINE

摘要

A washing method of a washing machine and the washing machine. The washing machine comprises an outer tub (1), an inner tub (2), a pulsator (3) and a driving device. The driving device is a bi-rotor direct driving motor, comprising two rotors (4, 5) and one stator (6), wherein one of the rotors (4) is connected with a shaft (21) of the inner tub, and the other one (5) is connected with a shaft (31) of the pulsator. During washing, the impeller (3) and the inner tub (2) are respectively driven by the two rotors (4, 5) to rotate independently. During washing, the driving device drives the inner tub (2) and the impeller (3) to rotate reversely. The inner tub (2) and the pulsator (3) change the rotation direction in every rotation cycle. The driving device drives the inner tub (2) and the impeller (3) to change the rotation direction asynchronously so that the inner tub (2) and the impeller (3) rotate in the same direction during the time difference of reversing. The washing machine changes the washing water stream so as to relieve the intertwining of the laundry due to the synchronous reversing of the inner tub and the pulsator, therefore reducing the wear of the laundry. The application of the direct driving with two rotors, changing the conventional way of transmitting torque through gear reduction, reduces the energy loss caused by sub process energy transmission and meanwhile the noise is reduced.
