Abstract
A pulsator device that generates a composite stream of water to improve performance of a washing machine. The pulsator device includes a first pulsator configured to be rotated about a rotary shaft, a shaft connected to the first pulsator such that the shaft is rotated with the first pulsator, the shaft being eccentric with respect to the rotary shaft, and a second pulsator rotatably coupled to the shaft.
Claims6
A washing machine, comprising:
- a tub;
- a rotary tub rotatably disposed in the tub;
- a first pulsator coupled to a drive shaft, at least part of the first pulsator being rotatably disposed in the rotary tub, the first pulsator having a recess around the drive shaft, the recess formed eccentric to the drive shaft;
- a shaft connected to the first pulsator such that the shaft revolves around the drive shaft, the shaft being inclined with respect to the drive shaft toward an outside of the first pulsator in a radial direction away from the drive shaft;
- and
- a second pulsator rotatably coupled to the shaft, the second pulsator being disposed in the recess of the first pulsator, wherein
- the second pulsator is inclined with respect to a horizontal direction,
- an inner periphery of the first pulsator is in a same plane as an outer periphery of the second pulsator, and
- the same plane is inclined with respect to the horizontal direction.
