Abstract

A laundry treatment apparatus including a cabinet comprising a front panel having a laundry introduction hole formed therein, a laundry accommodating unit provided in the cabinet including a predetermined space in which laundry introduced through the laundry introduction hole is held, a door which is coupled to the front panel and rotatable about a horizontal axis parallel to a bottom surface of the cabinet to open and close the laundry introduction hole, and a damper provided in the front panel and upwardly inclined with respect to the bottom surface of the cabinet, to elastically support the door.

Claims (45)

1. A laundry treatment apparatus comprising:

a cabinet forming an exterior appearance of the laundry treatment apparatus including a front panel;

a laundry introduction hole formed in the front panel;

a laundry accommodating unit provided in the cabinet including a predetermined space in which laundry introduced through the laundry introduction hole is held;

a door, coupled to the front panel and rotatable about a horizontal axis parallel to a bottom surface of the cabinet, to open and close the laundry introduction hole; and

a damper, provided in the front panel and upwardly inclined with respect to the bottom surface of the cabinet, to elastically support the door, wherein the damper comprises:

a damper housing provided in the front panel;

a piston including one end reciprocating in the damper housing and a free end supporting the door, wherein the free end of the piston is in contact with the door when the door closes the laundry introduction hole; and

a piston supporter provided in the damper housing to elastically support the piston.

2. The laundry treatment apparatus of claim 1 , wherein the door comprises:

an inclined surface provided in a lower end surface of the front panel, the surface being inclined in a direction away from the front panel,

wherein the free end of the piston supports the inclined surface.

3. The laundry treatment apparatus of claim 2 , wherein the piston reciprocates in a direction inclined a preset angle with respect to a line parallel to a bottom surface of the cabinet and at right angles to the horizontal axis.

4. A laundry treatment apparatus comprising:

a cabinet forming an exterior appearance of the laundry treatment apparatus including a front panel;

a laundry introduction hole formed in the front panel;

a laundry accommodating unit provided in the cabinet including a predetermined space in which laundry introduced through the laundry introduction hole is held;

a door, coupled to the front panel and rotatable about a horizontal axis parallel to a bottom surface of the cabinet, to open and close the laundry introduction hole; and

a damper, provided in the front panel and upwardly inclined with respect to the bottom surface of the cabinet, to elastically support the door,

a first hinge comprising a first shaft provided in the front panel to form a vertical axis perpendicular to the bottom surface of the cabinet and a first shaft accommodating portion provided in the door to accommodate the first shaft;

a second hinge comprising a second shaft coupled to the door to form the vertical axis with the first shaft, and a third shaft rotatably coupling the second shaft to the front panel to form the horizontal axis;

a third hinge comprising a fourth shaft provided in the door to form the horizontal axis with the third shaft, and a fourth shaft accommodating portion provided in the front panel to accommodate the fourth shaft;

a first bar reciprocating in the door to open and close the first shaft accommodating portion; and

a second bar reciprocating in the door to open and close the fourth shaft accommodating portion when the first bar is moved in a direction to open the first shaft accommodating portion.

5. The laundry treatment apparatus of claim 4 , wherein the door further comprises:

an inclined surface provided in a lower end surface of the front panel, the surface being inclined in a direction away from the front panel,

wherein the damper supports the inclined surface.

6. The laundry treatment apparatus of claim 5 , wherein the damper comprises,

a damper housing fixed to a rear surface of the front panel and inclined a preset angle with respect to a horizontal plane at right angles to the horizontal axis;

a piston reciprocating in a direction perpendicular to the inclined surface; and

a piston supporter provided in the damper housing to elastically support the piston.

7. The laundry treatment apparatus of claim 6 , wherein the piston includes one end reciprocating in the damper housing and a free end supporting the inclined surface.

8. The laundry treatment apparatus of claim 6 , wherein the free end of the piston is in contact with an inclined surface of the door when closing the laundry introduction hole.

9. The laundry treatment apparatus of claim 4 , further comprising:

a handle including a handle body, a handle body shaft, a pressure point, and a pressing portion,

wherein the handle body shaft is located at one end of the handle body and the pressing portion is located at the opposite end of the handle body with the pressing point lying there between, and

wherein operation of the handle requires pressure to be applied to the pressure point.

10. The laundry treatment apparatus of claim 9 , wherein operation of the handle causes reciprocation of one or more of the first bar and the second bar.

11. The laundry treatment apparatus of claim 9 , wherein the handle is included in a handle accommodating portion located in the door.

12. The laundry treatment apparatus of claim 4 , further comprising:

a handle including a handle body, a handle body shaft, a pressure point, and a pressing portion,

wherein the pressing point is located at one end of the handle body and the pressing portion is located at the opposite end of the handle body with the handle body shaft lying there between, and

wherein operation of the handle requires pressure to be applied to the pressure point.

13. The laundry treatment apparatus of claim 12 , wherein operation of the handle causes reciprocation of one or more of the first bar and the second bar.

14. The laundry treatment apparatus of claim 12 , wherein the handle is included in a handle accommodating portion located in the door.
