Abstract

A laundry treatment apparatus includes a tub body configured to store water, a tub cover configured to define an upper surface of the tub body, an introduction aperture defined through the tub cover, a supply aperture provided in the tub cover, and configured to enable supply of water into the tub body, a drum that is rotatably provided in the tub body, and that is configured to receive laundry, the drum including an opening in communication with the introduction aperture, a door configured to open and close the introduction aperture, and an ejection unit configured to eject water introduced into the supply aperture to at least one of the door or to the drum.

Claims

1. A tub body for storing water therein;

a tub cover for forming an upper surface of the tub body;

an introduction aperture formed through the tub cover;

a drum rotatably provided in the tub body for storing laundry therein, the drum having an opening communicating with the introduction aperture;

a door for opening and closing the introduction aperture; and

a rotating shaft for rotating the drum; and

one or more washing unit or ejecting at least some of water moved toward the tub cover to the door using centrifugal force generated while the drum is rotated.

2. The laundry treatment apparatus according to claim 1, wherein the rotating shaft extends from a bottom surface of the tub body toward the introduction aperture.

3. The laundry treatment apparatus according to claim 2, wherein the washing unit comprises a guide extending from an edge of the tub cover toward the introduction aperture.

4. The laundry treatment apparatus according to claim 3, wherein the washing unit further comprises a discharge unit for discharging water supplied through the guide in a direction in which the door is located

5. The laundry treatment apparatus according to claim 4, wherein at least two of the washing units being arranged so as to face each other with respect to the introduction aperture.

6. The laundry treatment apparatus according to claim 5, wherein the guide comprises:

a first guide for guiding water moved to the tub cover to the discharge unit when the drum is rotated in a clockwise direction; and

a second guide for guiding water moved to the tub cover to the discharge unit when the drum is rotated in a counterclockwise direction.

7. The laundry treatment apparatus according to claim 6, wherein

the washing unit further comprises a barrier protruding from the tub cover toward an upper surface of the drum, and

the discharge unit comprises:

a first discharge unit formed through the barrier for discharging water supplied through the first guide; and
