Background

The washing machine is a convenient and quick washing tool, and saves a lot of time in the daily washing process. The existing washing machines are generally classified into two types, i.e., a drum washing machine and a pulsator washing machine. The impeller washing machine turns clothes up and down in water through the reciprocating motion of an impeller in the modes of waterfall water flow, water jet, hand scrubbing washing and the like, rubs the clothes and the wall of a barrel in the water, and achieves the purpose of decontamination and cleaning under the action of a detergent; meanwhile, the pulsator washing machine saves more time than a drum washing machine, can add clothes at any time, is light in weight and is convenient to move. However, the conventional pulsator washing machine has the following disadvantages in the washing process, such as that in the pulsator of the conventional washing machine, the washing water is driven to move by the rotation of the base plate, the water basically rotates, and in addition, since the plurality of stirring blades are uniformly and radially distributed from the center to the outside on the base plate, the intensity of the washing water flow generated by the stirring blades is larger on the outer side of the base plate than on the inner side, and the friction force of the water to the clothes is also larger on the outer side of the base plate than on the inner side, so that in this case, the clothes to be washed are driven to gather from the place with large force to the place with small force, namely from the outer side to the inner side, the clothes are entangled, the clothes are seriously contacted with the pulsator base plate, the clothes abrasion is increased, and the washing uniformity is reduced.

Chinese patent with application number CN201210430832.8 discloses a low-winding low-abrasion impeller and a washing machine using the same, the impeller comprises a base plate and stirring blades arranged on the base plate, wherein the base plate is provided with at least one clamping groove; and stirring blades capable of rotating relative to the clamping grooves are arranged in the clamping grooves.

Chinese patent application No. CN01273989.8 discloses a washing machine impeller with a movable rod, wherein a device capable of beating clothes is arranged on the washing machine impeller. The beating device mainly comprises an impeller, a wave wheel disc and at least more than 1 movable rod, wherein the impeller is arranged below the wave wheel disc and is fixed with the movable rods above the wave wheel disc through holes in the wave wheel disc.

Although the technical scheme about anti-winding is provided from different angles in the prior art, the problems of winding of clothes and abrasion of the clothes are solved to a certain extent, in practical application, the effect is not ideal, the water flow direction of the inner barrel cannot be changed, the flow of the water flow is stable and less in change, the washing effect of the water flow on the clothes is difficult to guarantee, and the phenomena of abrasion and clothes winding still exist.
