ABSTRACT:
A pulsator of a washing machine for effectively washing small-sized or light weight articles. The pulsator has a rotating disc, and a cylindrical member having a chamber for receiving an article to be washed and integrally formed at a center of an upper surface of the rotating disc. The cylindrical member extends upward by a predetermined length. The pulsator has a lid for preventing the article received in the chamber from coming out of the chamber, and a plurality of vanes for generating a swirl shaped liquid flow. The vanes are regularly installed around an outer wall of the cylindrical member. The cylindrical member is formed at its outer wall with a plurality of holes for introducing/discharging a washing water into/from the chamber. The articles placed in the chamber of the pulsator are subjected to a relatively small centrifugal force, so the small-sized articles can be prevented from tangling with each other and prevented from being damaged. The pulsator has a simple construction and can be easily manufactured by molding process, so the manufacturing cost thereof is reduced.
