Abstract

A refrigerator includes a cabinet, a door, and a hinge connecting the door to an upper surface of the cabinet. The hinge includes a mounting part mounted on the cabinet and a hinge pin inserted into the door. The door includes a door body that has a hinge mounting part and is filled with an insulating material, and a panel assembly mounted on a front surface of the door body. The hinge mounting part is recessed into the door body and receives the hinge inserted at a position spaced apart from the upper end of the door body. A pin mounting hole into which the hinge pin is inserted is formed on a lower surface of the hinge mounting part, and an upper opening through which an electric wire directed into the door passes is formed on an upper surface of the hinge mounting part.

Claims (48)

1. A refrigerator comprising:

a cabinet that defines a storage space;

a door configured to open and close at least a portion of the storage space; and

a hinge that rotatably connects the door to the cabinet, the hinge comprising:

a mounting part disposed at the cabinet,

an extension part that extends forward relative to the mounting part, an end portion of the extension part being curved toward a side edge of the door,

a hinge pin that extends from the end portion of the extension part and is inserted into the door, the hinge pin defining a rotation axis of the door, and

a reinforcing part that is disposed between the mounting part and the extension part and extends forward in a front-rear direction from the mounting part to a portion above the door, the reinforcing part protruding laterally toward the side edge of the door relative to the hinge pin,

wherein the reinforcing part comprises a protrusion that protrudes from the extension part toward the side edge of the door,

wherein the extension part defines a recess between the protrusion and the end portion of the extension part, the recess being recessed inward away from the side edge of the door, and

wherein a horizontal width of the protrusion in a horizontal direction is greater than a horizontal width of the end portion of the extension part in the horizontal direction; wherein a horizontal distance between a side end of the protrusion and the side edge of the door is less than a horizontal distance between an outer surface of the hinge pin and the side edge of the door.

2. The refrigerator of claim 1 , wherein at least a portion of the protrusion is disposed above a space between a front surface of the cabinet and a rear surface of the door.

3. The refrigerator of claim 1 , wherein the protrusion is disposed above an upper surface of the door, and

wherein the protrusion is configured (i) to cover at least a portion of the upper surface of the door based on the door being closed and (ii) to cover an upper side of a space defined between a front surface of the cabinet and the side edge of the door based on the door being opened.

4. The refrigerator of claim 1 , wherein the protrusion extends from the extension part toward the side edge of the door in the horizontal direction.

5. The refrigerator of claim 1 , wherein a horizontal width of the reinforcing part in the horizontal direction is equal to a horizontal width of the mounting part in the horizontal direction.

6. The refrigerator of claim 1 , wherein the side end of the reinforcing part is configured to be arranged on the side edge of the door based on the door being closed.

7. The refrigerator of claim 1 , wherein the reinforcing part extends in the horizontal direction parallel to a front surface of the door.

8. The refrigerator of claim 1 , wherein the hinge pin is spaced apart from a side edge of the cabinet by a set distance in the horizontal direction, and

wherein a distance between the hinge pin and a corner of the door defines a rotation radius of the door that is less than or equal to the set distance.

9. The refrigerator of claim 1 , wherein the door comprises (i) a door body configured to face the storage space based on the door being closed and (ii) a panel assembly that is disposed at a front surface of the door body and defines a front outer appearance of the door, and

wherein the protrusion extends from the extension part to the side edge of the door in the horizontal direction.

10. The refrigerator of claim 9 , wherein the side edge of the door is recessed inward relative to a side edge of the cabinet in the horizontal direction, and

wherein a side end of the protrusion is configured to be arranged on the side edge of the door based on the door being closed, and

wherein a front surface of the panel assembly is configured to, based on the door being opened, be disposed at a position between the side end of the protrusion and the side edge of the cabinet.

11. The refrigerator of claim 10 , wherein the hinge pin is spaced apart from the side edge of the cabinet by a set distance in the horizontal direction, and

wherein a distance between the hinge pin and a corner of the panel assembly defines a rotation radius of the door that is less than or equal to the set distance.

12. The refrigerator of claim 11 , wherein a protrusion length of the protrusion relative to the hinge pin in the horizontal direction toward the side edge of the door is less than the rotation radius.

13. The refrigerator of claim 9 , wherein a front surface of the panel assembly is configured to, based on the door being opened, be positioned inward relative to a side edge of the cabinet by a first set distance in the horizontal direction, and

wherein a distance between the hinge pin and a corner of the panel assembly defines a rotation radius of the door that is greater than the first set distance.

14. The refrigerator of claim 13 , wherein the hinge pin is spaced apart from the side edge of the cabinet by a second set distance in the horizontal direction, and

wherein a protrusion length of the protrusion relative to the hinge pin in the horizontal direction is greater than the first set distance and less than the second set distance.

15. The refrigerator of claim 14 , wherein the rotation radius of the door that is less than or equal to the second set distance.

16. The refrigerator of claim 1 , wherein the door comprises (i) a door body configured to face the storage space based on the door being closed and (ii) a panel assembly that is disposed at a front surface of the door body and defines a front outer appearance of the door, and

wherein the hinge pin is disposed closer to the panel assembly than to the reinforcing part in the front-rear direction.

17. A refrigerator comprising:

a cabinet that defines a storage space;

a door configured to open and close at least a portion of the storage space; and

a hinge that rotatably connects the door to the cabinet, the hinge comprising:

a mounting part disposed at the cabinet,

an extension part that extends forward relative to the mounting part, an end portion of the extension part being curved toward a side edge of the door,

a hinge pin that extends from the end portion of the extension part and is inserted into the door, the hinge pin defining a rotation axis of the door, and

a reinforcing part that is disposed between the mounting part and the extension part and extends forward in a front-rear direction from the mounting part to a portion above the door, the reinforcing part protruding laterally toward the side edge of the door relative to the hinge pin,

wherein the door comprises (i) a door body configured to face the storage space based on the door being closed and (ii) a panel assembly that is disposed at a front surface of the door body and defines a front outer appearance of the door,

wherein the hinge pin is disposed closer to the panel assembly than to the reinforcing part in the front-rear direction,

wherein the reinforcing part comprises a protrusion that extends along a rear surface of the door body, and

wherein the side edge of the door is disposed closer to an end of the protrusion than to an outer surface of the hinge pin in a left-right direction.

18. The refrigerator of claim 17 , wherein the extension part defines a recess between the protrusion and the end portion of the extension part, the recess being recessed inward away from the side edge of the door.
