Abstract

A laundry treatment apparatus includes a cabinet and a drawer retractably provided in the cabinet. An accommodation unit is provided at the drawer and defines a space configured to receive washing water. The laundry treatment apparatus includes a guider. The guider includes a first body rotatably coupled to the cabinet, and a second body rotatably coupled to the first body and the drawer and configured to connect the first body to the drawer. A supply unit is connected to a water supply source. A water supply channel is provided along the guider and is configured to supply water between the supply unit and the accommodation unit.

Claims

1. A laundry treatment apparatus comprising:

a cabinet;

a drawer configured to be extracted from and retracted into the cabinet;

an accommodation unit provided in the drawer to store water therein;

a guider comprising;

a first body having a first end and a second end, the first end of the first body being rotatably coupled to the cabinet, and

a second body having a first end rotatably coupled to the drawer, and a second end rotatably coupled to the second end of the first body;

a water supply channel that is provided in the guider and that connects a water supply source and the accommodation unit;

a water discharge channel provided in the guider and configured to discharge water in the accommodation unit to an outside of the cabinet; and

a communication channel configured to provide communication between the water supply channel and the water discharge channel,

wherein the first body and the second body are configured to be located in a space between an upper surf ace of the drawer and an upper surface of the cabinet when the drawer is in a closed position.

2. The laundry treatment apparatus according to claim 1, wherein the communication channel is a pipe that connects the water supply channel and the water discharge channel directly.

3. The laundry treatment apparatus according to claim 1, wherein the first body and the second body are configured to be parallel to a width direction of the cabinet.

4. The laundry treatment apparatus according to claim 3, wherein the water discharge channel is formed as an external water pipe supported by the guider.

5. The laundry treatment apparatus according to claim 3, further comprising a discharge unit located below the guider and configured to discharge water in the accommodation unit to the outside of the accommodation unit,

wherein the water discharge channel comprises a first discharge channel formed as an internal channel inside the first body, a first water discharge pipe connected between the first discharge channel and the discharge unit, and a second water discharge pipe configured to guide water inside the first discharge channel to the outside of the cabinet.

6. The laundry treatment apparatus according to claim 5, wherein the communication channel is a pipe that is configured to provide communication between the water supply channel and one of the first discharge channel, the first water discharge pipe, or the second water discharge pipe.

7. The laundry treatment apparatus according to claim 5, wherein the water supply channel is formed as an external water pipe supported by the guider.

8. The laundry treatment apparatus according to claim 3, wherein the water supply channel comprises:

a first supply channel formed as an internal channel inside the first body;

a connecting pipe that connects the water supply source and the first supply channel; and

a water supply pipe supported by the second body and configured to supply water discharged from the first supply channel to the accommodation unit.

9. The laundry treatment apparatus according to claim 8, wherein the communication channel is a pipe that is configured to provide communication between the water supply pipe and the water discharge channel.

10. The laundry treatment apparatus according to claim 8, further comprising a discharge unit located below the guider and configured to discharge water in the accommodation unit to the outside of the accommodation unit,

wherein the water discharge channel comprises a first discharge channel formed as an internal channel inside the first body, a first water discharge pipe connected between the first discharge channel and the discharge unit, and a second water discharge pipe configured to guide water inside the first discharge channel to the outside of the cabinet, and

wherein the communication channel is a pipe configured to provide communication between the water supply pipe and one of the first discharge channel, the first water discharge pipe, or the second water discharge pipe.
