ABSTRACT:
The invention relates to a pulsator with an improved structure and more particularly to a pulsator having punching function used in the washing machine. The pulsator of the present invention is composed of such improved structure that a rotating member has a guiding dimple formed on the its upper end surface, and an elevating member has a guiding protrusion projected from the inner surface. According to such pulsator, non-symmetrical water flow and up-and-down water flow can be generated easily so that the entanglement of the washing articles can be minimized, and the washing is carried out effectively.
