Background

As a commonly used household appliance, a full-automatic pulsator type washing machine generally includes an outer tub, an inner tub disposed inside the outer tub, and a pulsator disposed inside the inner tub. The outer barrel is used as a water containing barrel and used for containing washing water, the inner barrel is used as a dewatering barrel and can be driven to rotate at a high speed for dewatering, and the impeller can be driven to rotate in the inner barrel in a forward and reverse direction to stir the washing water to form washing water flow so as to wash clothes.

The existing full-automatic impeller washing machine drives the impeller to rotate forward and backward to form washing water flow by controlling the motor during washing, and drives the impeller and the inner barrel to rotate at the same speed and the same direction at high speed during dewatering to realize centrifugal dewatering of clothes in the inner barrel. In the washing process, only the impeller rotates, the rotating mode is single, and the flow direction of formed washing water flow is too simple, so that the washing effect of the washing water flow on clothes is poor, the regular single impeller rotates forwards and backwards, and the clothes are wound seriously.

Aiming at the problems, the diversity of the washing water flow generated in the washing process is increased, the washing effect of the clothes can be increased, and the entanglement of the clothes can be reduced. Therefore, a dual-power washing machine appears, and the main difference from the traditional full-automatic pulsator washing machine is as follows: in the washing process, the relative rotation between the impeller and the inner barrel is realized through control, so, because two rotating parts of the impeller and the inner barrel rotate in the washing water, more various washing water flows can be generated in the washing water, the washing effect of clothes is improved, and the winding of the clothes can be lightened due to the diversity of the washing water flows.

The existing dual-power washing machine controls the inner barrel and the impeller to rotate oppositely in the washing process, generally realized by a speed reduction clutch device, and the combined action of a speed reduction gear train and a clutch mechanism of the speed reduction clutch device can realize the power transmission effect of one-in two-out, thereby realizing the power driving of the dual-power washing machine. However, the power driving mode of the dual-power washing machine is realized by the speed reduction clutch device, certain requirements are required on the structural design and durability of the speed reduction clutch device, and the rotating mode of the inner barrel and the impeller is limited by the design of the speed reduction clutch device.

Therefore, another implementation manner of implementing a dual-power washing machine is proposed, in which dual-power washing of the washing machine is implemented by a dual-rotor motor, the dual-rotor motor includes two rotors, the two rotors respectively drive the pulsator and the inner tub, and various operation manners of the pulsator and the inner tub can be implemented by controlling the operation of the dual-rotor motor, and the rotation speed and the rotation direction are controllable. However, in the dewatering process of the washing machine, the impeller and the inner barrel need to be kept to synchronously rotate at high speed, the dual power is realized by keeping the integrated mechanical locking of the impeller shaft and the inner barrel shaft through the speed reduction clutch device, for the double-rotor motor, the complete synchronous rotation of the two rotors needs to be ensured, the control requirement and the precision requirement are high, and the double-rotor motor has certain realization difficulty.

In view of this, the utility model discloses a specially propose the patent of this utility model.
