ABSTRACT:
A pulsator, which is installed in a washing tub of a washing machine, includes a base, a post protruded upwardly from a upper surface of the base, a plurality of blades extended radially with respect to the post and outwardly the base, and protruded upwardly on the upper surface of the base, and a plurality of vanes formed on a upper portion of the post, extended radially and outwardly with respect to the upper portion of the post. The plurality of blades develop a heart-type water flow in the washing tub, and the a plurality of vanes develop a water flow at a central portion of the heart-type water flow, thereby the twisting and tangling of the laundry caused by the heart-type water flow can be minimized.
