Washings overturned washing method by impeller of washing machine

The invention discloses a washings overturned washing method by an impeller of a washing machine. In the method, impeller vanes are arranged on the impeller in the radial direction, and an upward raised impeller neck is arranged on the position of a central axis. The washings overturned washing comprises a forward moving process and a backward moving process: when the washings are on the bottom of an inner barrel and move towards the center of the impeller, the washings moving mode is that washings make spiral ascending motion upwards along the impeller vanes while revolving around the central axis, and move upwards along the impeller vanes to the impeller neck in the center of the impeller; when the washings move to the top of the impeller neck, the washings move upwards due to inertia; after short upcast, the washings make external overturn revolution under the action of centrifugal force and bottom washings until the washings reach the position of inner barrel wall far away from the center of the impeller, and then the washings are pulled downwards by the washings on the bottom and the washings contacted with the impeller until the washings reach the bottom of the barrel; and while the washings move, the washings make overturned motion. The washing method has the characteristics of comprehensiveness, sufficiency, repetition and high efficiency.
