Abstract

A laundry treatment apparatus is disclosed. The laundry treatment apparatus includes a first cabinet, a first drawer drawably disposed in the first cabinet, a first receiver disposed in the first drawer so as to contain laundry therein, a second cabinet disposed under the first cabinet so as to support the first cabinet, a second receiver disposed in the second cabinet so as to contain laundry, a cabinet connecting unit for connecting the first cabinet to the second cabinet, and a cabinet supporting unit for preventing the first cabinet from falling down from the second cabinet when the first drawer is taken out of the first cabinet.

First claim

The invention claimed is:

1. A laundry treatment apparatus comprising:
a first cabinet;
a first drawer located in the first cabinet and configured to be drawn into and out of the first cabinet;
a first receiver located in the first drawer and configured to receive laundry therein;
a second cabinet located under the first cabinet and configured to support the first cabinet;
a second receiver located in the second cabinet and configured to receive laundry therein;
a cabinet connector configured to fix the first cabinet to the second cabinet; and
a cabinet supporter configured to restrict the first cabinet from falling down from the second cabinet when the first drawer is drawn out of the first cabinet,
wherein the cabinet supporter is configured to contact a surface on which the second cabinet is mounted, and configured to extend from the second cabinet in a direction in which the first drawer is drawn out, and
wherein a length between a front surface of the first cabinet and a free end of the cabinet supporter is equal to or longer than a length between a front surface of the first cabinet and a center of mass of the first drawer when the first drawer is drawn out of the first cabinet.

2. The laundry treatment apparatus according to claim 1 , wherein the cabinet supporter includes a bar or plate, the bar or plate extending from the second cabinet in a direction in which the first drawer is drawn out and contacting a surface on which the second cabinet is mounted.

3. A laundry treatment apparatus comprising:
a first cabinet;
a first drawer located in the first cabinet and configured to be drawn into and out of the first cabinet;
a first receiver located in the first drawer and configured to receive laundry therein;
a second cabinet located under the first cabinet and configured to support the first cabinet;
a second receiver located in the second cabinet and configured to receive laundry therein;
a cabinet connector configured to fix the first cabinet to the second cabinet; and
a cabinet supporter configured to restrict the first cabinet from falling down from the second cabinet when the first drawer is drawn out of the first cabinet,
wherein the cabinet supporter comprises:
a support body that extends from the second cabinet in a direction opposite to a direction in which the first drawer is drawn out; and
a fastening member configured to secure the support body to a surface on which the second cabinet is mounted.

4. The laundry treatment apparatus according to claim 3 , further comprising:
a stationary body secured to a bottom surface of the second cabinet; and
an adjusting body rotatably coupled to the stationary body and configured to adjust a height of the second cabinet,
wherein the support body is detachably coupled to the adjusting body.

5. The laundry treatment apparatus according to claim 4 , further comprising:
a contact body provided at the adjusting body and contacting a surface on which the second cabinet is mounted;
a flange provided at the support body and configured to receive the contact body; and
a slit provided in the support body and configured to receive the adjusting body.

6. A laundry treatment apparatus comprising:
a first cabinet;
a first drawer located in the first cabinet and configured to be drawn into and out of the first cabinet;
a first receiver located in the first drawer and configured to receive laundry therein;
a second cabinet located under the first cabinet and configured to support the first cabinet;
a second receiver located in the second cabinet and configured to receive laundry therein;
a cabinet connector configured to fix the first cabinet to the second cabinet; and
a cabinet supporter configured to restrict the first cabinet from falling down from the second cabinet when the first drawer is drawn out of the first cabinet,
wherein the cabinet supporter comprises:
a wire secured to a rear surface of the first cabinet; and
a fastening member configured to secure the wire to a surface on which the second cabinet is mounted or to a wall defining a space accommodating the second cabinet.

7. The laundry treatment apparatus according to claim 1 , further comprising:
a second driving unit configured to rotate the second receiver;
a second controller configured to control the second driving unit; and
a second coupling unit configured to permit the second controller to control the second driving unit to be operated based on the first cabinet being mounted on an upper surface of the second cabinet.

8. The laundry treatment apparatus according to claim 7 , wherein the second coupling unit is configured to open or close a circuit that supplies power to the second driving unit depending on whether the first cabinet is located on the second cabinet.

9. The laundry treatment apparatus according to claim 7 , wherein the second coupling unit is configured to open or close a circuit that connects the second controller to the second driving unit depending on whether the first cabinet is located on the second cabinet.

10. The laundry treatment apparatus according to claim 7 , further comprising a press portion provided at the first cabinet,
wherein the second coupling unit comprises:
a coupling body that extends through the upper surface of the second cabinet, the coupling body being pressed by the press portion; and
a circuit connector configured to open or close a circuit that supplies power to the second driving unit or to the second controller depending on a position of the coupling body.

11. The laundry treatment apparatus according to claim 10 , wherein the cabinet connector comprises:
a first connector provided on a bottom surface of the first cabinet and configured to serve as the press portion; and
a second connector provided on the second cabinet and configured to be coupled to the first connector.

12. The laundry treatment apparatus according to claim 10 , further comprising:
a first driving unit configured to rotate the first receiver;
a first controller configured to control the first driving unit;
