Patent ID: 8448481

Claim:
A pulsator unit for washing machines to generate a washing water current comprising: a first pulsator connected to a washing shaft of the washing machine, the first pulsator including rotary blades which protrude in a radial direction to generate a rotating water current; a rod member installed on the upper surface of the first pulsator such that the rod member is tilted against the washing shaft and rotates in conjunction with the first pulsator, the rod member being tilted toward a central axis of the first pulsator; and a second pulsator shaft-coupled with the rod member such that the second pulsator is relatively rotated against the rod member, wherein a designated angle of the rod member determines a rising and falling range of the second pulsator so that the second pulsator generates a rising and falling water current, and a center of a wobbling movement of the second pulsator is formed at the intersection between the central axis of the first pulsator and a central axis of the rod member.
