A pulsator of washing machine and a washing machine

Abstract

A pulsator of washing machine and a washing machine, a base body of the pulsator is disk-shaped. A central portion is arranged at and protrudes from a center of the base body of the pulsator, on an upper surface of the base body is provided with and a stirring blade protruding the base body and a groove, the stirring blade extends from the central portion of the base body to a outer periphery of the base body. Moreover, a bottom surface of the base body is provided with a smoothly undulating surface corresponding to the upper surface. The undulating surface does not stiffly protrude from the bottom surface of the base body, so there is no hard angle formed between the undulating surface, or between the undulating surface and the other surface of the base body.
