Abstract

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

First claim

What is claimed is:

1. A refrigerator, comprising:
a cabinet having a storage chamber; and
a door configured to open and close the storage chamber, wherein the door comprises:
an outer plate formed of a metal material and having a front surface defining a first exterior of the door and a plate bent part bent rearward along a perimeter of an opening formed at a center portion of the outer plate;
a front panel formed of a glass material and inserted into the opening, the front panel having a front surface defining a second exterior of the door and a side surface that faces the plate bent part;
a bezel that extends along a perimeter of a rear surface of the front panel to restrict transmission of light;
a door liner spaced apart from the outer plate and having a rear surface defining a third exterior of the door;
a door frame configured to connect the outer plate to the door liner, at least one of an upper surface or a rear surface of the door frame defining a fourth exterior of the door; and
an insulation filled in an insulating space defined by the outer plate, the door liner, the door frame, and the front panel, wherein the first exterior, the second exterior, and the bezel are viewable at a front side of the refrigerator in a state in which the door closes the storage chamber.

2. The refrigerator of claim 1 , wherein an extension length of the plate bent part is greater than a thickness of the front panel.

3. The refrigerator of claim 1 , wherein the bezel is disposed behind the front surface of the outer plate.

4. The refrigerator of claim 1 , wherein the bezel is disposed in a region defined by the plate bent part.

5. The refrigerator of claim 1 , wherein the insulation is in contact with the plate bent part.

6. The refrigerator of claim 1 , wherein the door frame comprises a plurality of injection holes spaced apart from each other through which a foaming solution which forms the insulation is injected.

7. The refrigerator of claim 1 , further comprising a door lighting unit provided in the door.

8. The refrigerator of claim 7 , wherein a brightness of the second exterior of the door when the door lighting unit is turned on is greater than a brightness of the second exterior of the door when the door lighting unit is turned off.

9. The refrigerator of claim 1 , further comprising a detector to detect an input signal applied to the front panel, wherein the detector faces the bezel.

10. The refrigerator of claim 1 , wherein the door further comprises a heater that faces the bezel.

11. The refrigerator of claim 10 , wherein the heater is disposed in a region defined by the plate bent part.

12. A refrigerator, comprising:
a cabinet having a storage chamber; and
a door configured to open and close the storage chamber, wherein the door comprises:
an outer plate formed of a metal material and having a front surface defining a first exterior of the door and a plate bent portion that extends rearward perpendicular to the front surface along a perimeter of an opening formed at a center portion of the outer plate;
a front panel formed of a glass material and inserted into the opening, the front panel having a front surface defining a second exterior of the door and a side surface that faces the plate bent portion;
a bezel that extends along a perimeter of a rear surface of the front panel to restrict transmission of light, wherein the bezel is disposed in a region defined by the plate bent portion;
a door liner spaced apart from the outer plate and having a rear surface defining a third exterior of the door;
a door frame configured to connect the outer plate to the door liner, at least one of an upper surface or a rear surface of the door frame defining a fourth exterior of the door; and
an insulation filled in an insulating space defined by the outer plate, the door liner, the door frame, and the front panel, wherein the first exterior, the second exterior, and the bezel are viewable at a front side of the refrigerator in a state in which the door closes the storage chamber.

13. The refrigerator of claim 12 , wherein an extension length of the plate bent part is greater than a thickness of the front panel.

14. The refrigerator of claim 12 , wherein the bezel is disposed behind the front surface of the outer plate.

15. The refrigerator of claim 12 , wherein the insulation is in contact with the plate bent portion.

16. The refrigerator of claim 12 , wherein the door frame comprises a plurality of injection holes spaced apart from each other through which a foaming solution which forms the insulation is injected.

17. The refrigerator of claim 12 , further comprising a door lighting unit provided in the door.

18. The refrigerator of claim 17 , wherein a brightness of the second exterior of the door when the door lighting unit is turned on is greater than a brightness of the second exterior of the door when the door lighting unit is turned off.

19. The refrigerator of claim 12 , further comprising a detector to detect an input signal applied to the front panel, wherein the detector faces the bezel.

20. The refrigerator of claim 12 , wherein the door further comprises a heater that faces the bezel, wherein the heater is disposed in a region defined by the plate bent portion.
