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.
Claims30
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 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 the X-axis direction and the Y-axis direction with respect to an X-Y plane perpendicular to the rotary shaft.
2 more elements
A washing machine comprising:
- a first pulsator rotated around a rotary shaft;
- a shaft inclined on the first pulsator so as to be rotated together with rotation of the first pulsator;
- 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.
2 more elements
A pulsator device for washing machines comprising:
- a first pulsator rotated around a rotary shaft in a regular direction and the reverse direction;
- and
- a second pulsator selectively rotated according to a rotating direction of the first pulsator.
A pulsator device for washing machines comprising:
- a first pulsator rotated around a rotary shaft, and provided with a plurality of planes formed on the upper surface thereof and inclined at different angles with respect to the horizontal plane;
- a plurality of recesses, each of which is formed on each inclined plane;
- a plurality of shafts, each of which is disposed on the bottom of each recess so as to have a biaxial inclination angle structure;
- and
- a plurality of second pulsators, each of which is rotatably provided on each shaft.
