The ultrasound generator applies ultrasonic energy to the washing water to cause chaotic oscillation of the bubbles.
Claims17
A washing machine comprising:
- a tub;
- a drum rotatably disposed inside the tub;
- an agitator having a cylindrical shape, disposed in the drum, and configured to rotate about a central axis of the cylindrical shape;
- and
- an ultrasound generator having a cylindrical shape with a lower part coupled at a connection point with an upper part of the agitator to extend a vertical and axial length of the agitator along the central axis, and configured to emit ultrasonic waves to washing water loaded in the drum, to generate bubbles in the washing water,
- wherein an exterior circumference of the lower part of the ultrasound generator at the connection point is substantially flush with an exterior circumference of the upper part of the agitator at the connection point to provide a smooth transition from the ultrasound generator to the agitator to prevent an entanglement of laundry at the connection point.
