Abstract

The present invention provides an oven including: a cabinet having a cooking space open forward; a door rotating to open/close the cooking space; and a rotary hinge disposed on the front of the cabinet to rotate the door in various directions, in which the door includes: a first ink moving in a first direction; and a second link moving in a second direction perpendicular to the first direction by movement of the first link, and the rotational direction of the door depends on movement of the first link.

First claim

What is claimed is:

1. An oven comprising:
a cabinet that defines a cooking space and that defines an opening at a front of the cabinet;
a door configured to rotate relative to the cabinet to open and close at least a portion of the opening at the front of the cabinet; and
a rotary hinge that is located at the front of the cabinet and that allows the door to rotate relative to the cabinet in a plurality of rotation directions,
wherein the door includes:
a door case,
a handle located at a front of the door case,
a first link configured to move in a first direction relative to the cabinet,
a second link configured to, based on movement of the first link in the first direction, move in a second direction that is perpendicular to the first direction, and
an operation unit that is located at the handle, that is configured to cause the first link to move relative to the cabinet, and that is configured to pass through the door case to press the first link, and

wherein the door is configured to rotate in a first rotation direction among the plurality of rotation directions based on movement of the first link relative to the cabinet.

2. The oven according to claim 1 , wherein the operation unit is configured to press the first link in a direction that is perpendicular to the first direction and to the second direction.

3. The oven according to claim 1 , wherein the first direction comprises a first lateral direction toward a first side of the door and a second lateral direction toward a second side of the door, and
wherein the second direction is a vertical direction of the cabinet.

4. The oven according to claim 3 , wherein the second link is configured to:
move upward based on the first link moving toward the first side of the door in the first lateral direction; and
move downward based on the first link moving toward the second side of the door in the second lateral direction.

5. The oven according to claim 1 , wherein the first link includes a guide configured to contact the operation unit and the second link.

6. The oven according to claim 5 , wherein the second link includes a slide slope that is inclined with respect to the second direction, and
wherein the guide is configured to move relative to the slide slope in a state in which the guide contacts the slide slope.

7. The oven according to claim 1 , wherein the first link is configured to press an upper end of the second link.

8. The oven according to claim 1 , wherein the first link includes a first elastic member configured to provide first elastic force that causes the first link to move to an initial position of the first link.

9. The oven according to claim 8 , wherein the second link includes a second elastic member configured to provide second elastic force that causes the second link to move to an initial position of the second link.

10. The oven according to claim 9 , wherein an elastic modulus of the first elastic member is greater than an elastic modulus of the second elastic member.

11. The oven according to claim 9 , wherein the second elastic member is configured to be stretched based on the first elastic member being compressed.

12. The oven according to claim 1 , further comprising:
a coupling hinge located at the cabinet and spaced apart from the rotary hinge in the first direction; and
a fixed hinge located at the cabinet and spaced apart from the rotary hinge in the second direction.

13. The oven according to claim 12 , wherein the door is configured to open and close at least a portion of the opening at the front of the cabinet (i) in a first mode in which the door rotates about a side end of the cabinet or (ii) in a second mode in which the door rotates about a lower end of the cabinet.

14. The oven according to claim 12 , wherein the first link is configured to couple to the fixed hinge.

15. The oven according to claim 12 , wherein the second link is configured to couple to the coupling hinge.

16. The oven according to claim 13 , wherein the first link is configured to couple to the fixed hinge in the first mode, and to separate from the fixed hinge in the second mode.

17. The oven according to claim 13 , wherein the second link is configured to separate from the fixed hinge in the first mode, and to couple to the fixed hinge in the second mode.

18. An oven comprising:
a cabinet that defines a cooking space and that defines an opening at a front of the cabinet;
a door configured to rotate relative to the cabinet to open and close at least a portion of the opening at the front of the cabinet; and
a rotary hinge that is located at the cabinet and that allows the door to rotate relative to the cabinet in a plurality of rotation directions,
wherein the door includes:
a first link configured to move in a first direction relative to the cabinet, and
a second link configured to, based on movement of the first link in the first direction, move in a second direction that is perpendicular to the first direction, and

wherein the door is configured to, based on movement of the first link in the first direction, open and close at least a portion of the opening at the front of the cabinet (i) in a first mode in which the door rotates about a side end of the cabinet or (ii) in a second mode in which the door rotates about a lower end of the cabinet,
wherein the rotary hinge includes:
a coupling base coupled to the cabinet,
a rotary rib connected to the coupling base and configured to, in the first mode, rotate about a rotary shaft relative to the coupling base, and
a side shaft that extends in a direction that is perpendicular to the rotary shaft of the rotary rib.

19. The oven according to claim 18 , wherein the rotary hinge is coupled to a side of a lower end of the cabinet.

20. The oven according to claim 18 , wherein the coupling base protrudes from a front of the cabinet.

21. The oven according to claim 18 , wherein the rotary hinge further includes a down shaft configured to connect the rotary rib to the coupling base.
