Abstract
A pulsator device in which a second pulsator performs different movements according to rotating directions of a first pulsator so as to reduce water consumption and improve washing performance.
Claims20
A pulsator device for washing machines comprising:
- a first pulsator rotated around a rotary shaft;
- a shaft fixed to the first pulsator so as to revolve around the rotary shaft, and rotated together with a rotation of the first pulsator;
- and
- a second pulsator rotatably connected to the shaft,
- wherein the shaft is disposed so as to have a biaxial inclination angle structure in an X-axis direction and a Y-axis direction with respect to an X-Y plane perpendicular to the rotary shaft, and
- wherein the first pulsator includes a recess formed on an upper portion thereof, and the second pulsator is disposed in the recess, the recess being eccentrically disposed in a radial direction of the first pulsator.

A washing machine comprising:
- a first pulsator rotated around a rotary shaft;
- a shaft connected to the first pulsator so as to be rotated together with a rotation of the first pulsator, and inclined;
- a second pulsator rotatably connected to the shaft so as to be rotated in a first direction and in a second direction opposite to the first direction;
- and
- a clutch unit to intermit rotation of the second pulsator so as to cause the second pulsator to be rotated in any one direction out of the first direction and the second direction, and
- wherein the first pulsator includes a recess formed on an upper portion thereof, and the second pulsator is disposed in the recess, the recess being eccentrically disposed in a radial direction of the first pulsator.
3 more elements
A pulsator device for washing machines comprising:
- a first pulsator rotated around a rotary shaft in a regular direction and a reverse direction;
- a second pulsator selectively rotated according to a rotating direction of the first pulsator, and
- a shaft connected to the first pulsator so as to be rotated together with a rotation of the first pulsator, and inclined,
- wherein the second pulsator is rotatably connected to the shaft, and
- wherein the first pulsator includes a recess formed on an upper portion thereof, and the second pulsator is disposed in the recess, the recess being eccentrically disposed in a radial direction of the first pulsator.
