Abstract

A refrigerator includes a cabinet in which a refrigerating compartment and a freezing compartment, each of which has an opened front surface, are defined, and a door configured to open and close the refrigerating compartment. The refrigerating compartment door includes a first door rotatably mounted on the cabinet, and a second door provided in front of the first door and configured to rotate in the same direction as the first door so as to open and close at least a portion of a front surface of the first door. The first door includes an ice-making chamber which is defined in the first door and in which an ice maker is accommodated, and a door storage portion provided in front of the ice-making chamber and opened and closed by the second door to store food.

Claims (52)

1 . A refrigerator comprising:

a cabinet that has a refrigerating compartment and a freezing compartment, each of the refrigerating compartment and the freezing compartment having a front opening; and

a refrigerating compartment door configured to open and close at least a portion of the refrigerating compartment,

wherein the refrigerating compartment door comprises:

a first door rotatably disposed at the cabinet, and

a second door disposed at a front side of the first door and configured to rotate relative to the first door to thereby open and close at least a portion of the front side of the first door,

wherein the first door comprises:

an ice-making chamber,

an ice maker accommodated in the ice-making chamber,

a door storage disposed forward relative to the ice-making chamber and configured to store food, the door storage being configured to be opened and closed by the second door,

a dispenser disposed at a front surface of the first door, the dispenser being disposed below the door storage and configured to dispense ice from the ice-making chamber,

a supply duct configured to communicate the refrigerating compartment with the door storage, the supply duct being configured to introduce cold air from the refrigerating compartment into the door storage, and

a through-portion that passes through a lower portion of the first door and that is disposed below the dispenser, the through-portion being configured to discharge air from the door storage to the refrigerating compartment.

2 . The refrigerator according to claim 1 , wherein the ice-making chamber is recessed from a rear surface of the first door and defines a rear opening at the rear surface,

wherein the door storage is recessed from the front surface of the first door, and

wherein the first door further comprises an ice-making chamber door configured to open and close the rear opening of the ice-making chamber.

3 . The refrigerator according to claim 1 , wherein a rear surface of the second door is recessed and defines at least a portion of the door storage.

4 . The refrigerator according to claim 1 , wherein the door storage is disposed between the first door and the second door in a state in which the second door is closed.

5 . The refrigerator according to claim 1 , wherein the second door is configured to close the door storage and the dispenser simultaneously.

6 . The refrigerator according to claim 5 , wherein the second door comprises a panel assembly that overlaps with at least an area of each of the door storage and the dispenser, the panel assembly being configured to allow a rear side of the second door to be visible from an outside of the cabinet.

7 . The refrigerator according to claim 6 , further comprising a display disposed between the door storage and the dispenser,

wherein the panel assembly is configured to allow the display to be visible therethrough from the outside of the cabinet.

8 . The refrigerator according to claim 6 , further comprising a door light disposed at the first door or the second door, the door light being configured to be turned on and off by manipulation of a user and to selectively illuminate the door storage.

9 . The refrigerator according to claim 1 , wherein the supply duct passes through the first door, the supply duct defining a passage that bypasses the ice-making chamber and that is configured to guide cold air from the refrigerating compartment to the door storage.

10 . The refrigerator according to claim 9 , wherein the first door further comprises a storage fan configured to cause the cold air to flow through the supply duct.

11 . The refrigerator according to claim 1 , wherein the first door further comprises:

an ice outlet defined at a top surface of the through-portion and configured to discharge ice from the ice-making chamber; and

a manipulation member disposed at the top surface of the through-portion and configured to be manipulated for dispensing the ice through the ice outlet.

12 . The refrigerator according to claim 1 , wherein the first door further comprises a second door storage defined at the through-portion and configured to store food.

13 . The refrigerator according to claim 12 , wherein the second door is configured to open and close the through-portion, and

wherein the second door comprises a panel assembly that is configured to allow the door storage and the second door storage to be visible from an outside of the cabinet.

14 . The refrigerator according to claim 1 ,

wherein the second door is configured to open and close the door storage that is disposed above the dispenser.

15 . The refrigerator according to claim 14 , wherein the first door further comprises a protrusion that is disposed at the lower portion of the first door and that protrudes forward relative to the door storage, and

wherein the dispenser is disposed at the protrusion.

16 . The refrigerator according to claim 1 , wherein the second door comprises:

a door panel that defines a front surface of the refrigerating compartment door; and

an insulation material that is provided inside the door panel and that extends from an upper end of the door panel and a lower end of the door panel.

17 . A refrigerator comprising:

a cabinet that has a refrigerating compartment and a freezing compartment, each of the refrigerating compartment and the freezing compartment having a front opening; and

a refrigerating compartment door configured to open and close at least a portion of the refrigerating compartment,

wherein the refrigerating compartment door comprises:

a first door rotatably disposed at the cabinet, and

a second door disposed at a front side of the first door and configured to rotate relative to the first door to thereby open and close at least a portion of the front side of the first door,

wherein the first door comprises:

an ice-making chamber,

an ice maker accommodated in the ice-making chamber,

a door storage disposed forward relative to the ice-making chamber and configured to store food, the door storage being configured to be opened and closed by the second door,

a dispenser disposed at a front surface of the first door, the dispenser being disposed below the door storage and configured to dispense ice from the ice-making chamber,

a supply duct that passes through the first door from an upper side of the ice-making chamber and that fluidly communicates an upper portion of the door storage with the refrigerating compartment, the supply duct being configured to supply cold air from the refrigerating compartment to the door storage, and

a discharge duct that passes through the first door from a lower side of the ice-making chamber and that fluidly communicates a lower portion of the door storage with the refrigerating compartment, the discharge duct being configured to discharge air from the door storage to the refrigerating compartment, and
