Abstract

The laundry treating apparatus includes a door to open and close the introduction port about a first rotational or a second rotational axis which is different from first rotational axis. A first switching unit is provided in the door to allow rotation of door about the first rotational axis, and a second switching unit is provided in the door to allow rotation of the door about the second rotational axis. A lock fixes a position of at least one of the first switching unit or second switching unit when the door opens the introduction port. As can be appreciated, the mechanism used for the laundry apparatus may be applicable to other home appliances or non-home appliances where two different rotational axes may be needed to open and close a door.

First claim

What is claimed is:

1. A laundry treating apparatus comprising:
a cabinet having a front panel having an introduction port;
a chamber provided in the cabinet to receive laundry introduced through the introduction port;
a door configured to open and close the introduction port selectively about one of a first rotational axis and a second rotational axis, the second rotational axis being different from the first rotational axis;
a first switching unit provided at the door, and based on movement thereof, the first switching unit is configured to couple the door to the front panel to be rotatable about the first rotational axis;
a second switching unit provided at the door, and based on movement thereof, the second switching unit is configured to couple the door to the front panel to be rotatable about the second rotational axis, wherein the second switching unit is configured to couple the door to the front panel when the first switching unit uncouples the door from the front panel; and
a lock configured to fix a position of at least one of the first switching unit or the second switching unit when the door is opened,
wherein the lock further includes:
a lock body provided in the door to be movable in the thickness direction of the door;
a fixing unit supported by the lock body and configured to be detachably coupled to one of the first switching unit and the second switching unit;
a body support unit arranged between the lock body and the door to elastically support the lock body; and
a body push unit supported by the lock body and extending through the door to be exposed from the door, wherein the body push unit is adapted to be pressed by the front panel when the door is closed so as to detach the fixing unit from the one of the first switching unit and the second switching unit.

2. The laundry treating apparatus according to claim 1 , wherein the first or second switching unit includes a first fastening unit and a second fastening unit spaced apart from each other by a predetermined distance in a direction in which the first or second switching unit moves such that fixing unit can be selectively and detachably coupled thereto.

3. The laundry treating apparatus according to claim 2 , wherein
the first fastening unit and the second fastening unit are provided at the first switching unit,
a distance from a side of the door to the first fastening unit is less than a distance from the side to the second fastening unit, and
the door is configured to rotate about the first rotational axis when the lock is coupled to the second fastening unit and about the second rotational axis when the lock is coupled to the first fastening unit.

4. The laundry treating apparatus according to claim 2 , wherein
the first fastening unit and the second fastening unit are provided at the second switching unit,
a distance from a top of the door to the first fastening unit is greater than a distance from the top to the second fastening unit, and
the door is configured to rotate about the first rotational axis when the lock is coupled to the first fastening unit and about the second rotational axis when the lock is coupled to the second fastening unit.

5. The laundry treating apparatus according to claim 1 , wherein
the first switching unit is configured to move in a width direction of the door, and
the second switching unit is configured to move in a height direction of the door.

6. The laundry treating apparatus according to claim 1 , further comprising an elastic support unit to bias at least one of the first switching unit or the second switching unit so that the door is rotatable about the first rotational axis.

7. The laundry treating apparatus according to claim 6 , wherein the elastic support unit comprises a second support unit provided at the door to bias the second switching unit so that the door is not rotatable about the second rotational axis.

8. The laundry treating apparatus according to claim 6 , wherein the elastic support unit comprises:
a first support unit provided at the door to bias the first switching unit toward the first rotational axis while elastically supporting the first switching unit; and
a second support unit provided at the door to bias the second switching unit away from the second rotational axis while elastically supporting the second switching unit.

9. The laundry treating apparatus according to claim 6 , the elastic support unit is adapted to bias the first switching unit to close the first shaft receiving unit and to bias the second switching unit to open the fourth shaft receiving unit when the door is closed.

10. The laundry treating apparatus according to claim 1 , wherein the lock further comprises:
a body flange extending from the lock body such that the fixing unit is supported by the body flange, wherein the body push unit is adapted to be pressed by the front panel when the door is closed so as to move the lock body away from the first or second switching unit.

11. The laundry treating apparatus according to claim 10 , wherein
the first fastening unit and the second fastening unit are fastening holes formed through the first or second switching unit, and
the fixing unit comprises a first fixing protrusion protruding from the body flange to be insertable into the first fastening unit and the second fastening unit.

12. The laundry treating apparatus according to claim 11 , wherein the fixing unit further comprises a second fixing protrusion protruding from the first fixing protrusion, the second fixing protrusion having a smaller with than the first fixing protrusion.

13. The laundry treating apparatus according to claim 1 , further comprising a handle provided at the door to move the first or second switching unit in a direction in which the door is not rotatable about the first rotational axis.

14. The laundry treating apparatus according to claim 13 , wherein the handle comprises:
a handle body exposed out of the door;
a body rotation shaft coupling the handle body and the door to each other such that the handle body can rotate away from the front panel; and
a push unit rotatable about the body rotation shaft by the handle body to move any one of the first and second switching units.

15. The laundry treating apparatus according to claim 1 , further comprising:
a first hinge comprising a first shaft provided at the cabinet to define the first rotational axis and a first shaft receiving unit provided at the door to receive the first shaft, the first shaft receiving unit being adapted to be opened and closed by the first switching unit;
a second hinge comprising a second shaft coupled to the door to define the first rotational axis together with the first shaft and a third shaft rotatably fixing the second shaft to the cabinet while defining the second rotational axis; and
a third hinge comprising a fourth shaft provided at the cabinet to define the second rotational axis together with the third shaft and a fourth shaft receiving unit provided at the door to receive the fourth shaft, the fourth shaft receiving unit being adapted to be opened and dosed by the second switching unit.

16. The laundry treating apparatus according to claim 15 , wherein
the first switching unit comprises a first free end provided such that the first free end can move in a width direction of the door to open and close the first shaft receiving unit and a second free end contacting the second switching unit, and
the second switching unit comprises a third free end provided such that the third free end can move in a height direction of the door to open and close t
