Abstract

A refrigerator includes: a cabinet in which a refrigerating compartment is provided; a first door connected to the cabinet to open and close the refrigerating compartment and having an opening; a housing provided in the first door and accessible through the opening therein; an ice making room provided in the housing; a storage room that is provided below the ice making room and maintained at a temperature different from that of the refrigerating compartment; a guide duct provided below the ice making room to guide discharge of ice; a second door connected to the first door; a dispenser disposed on a front surface of the second door; and a discharge duct provided in the second door, wherein, when the second door is closed, the guide duct communicates with the discharge duct, and ice made in the ice making room is discharged to the dispenser.

Claims (35)

1. A refrigerator comprising:

a cabinet that defines a refrigerating compartment;

a first door connected to the cabinet and configured to open and close the refrigerating compartment, the first door defining an opening;

a housing provided in the first door and accessible through the opening therein;

an ice making room provided in the housing;

a guide duct provided below the ice making room and configured to guide discharge of ice;

a second door connected to the first door;

a dispenser provided in the second door; and

a discharge duct provided in the second door at an upper position of the dispenser,

wherein the dispenser and the discharge duct are configured to, based on the second door being moved from a closed position to an opened position relative to the first door, move together with the second door to separate from the guide duct, and

wherein the guide duct is configured to, based on the second door being moved from the opened position to the closed position relative to the first door, communicate with the discharge duct to allow ice made in the ice making room to be discharged to the dispenser.

2. The refrigerator of claim 1 , further comprising a storage room provided below the ice making room and maintained at a temperature different from that of the refrigerating compartment.

3. The refrigerator of claim 2 , further comprising a partition wall that defines the ice making room and the storage room,

wherein a part of a bottom surface of the partition wall on which an outlet of the guide duct is disposed and a top surface of the dispenser on which an inlet of the discharge duct is disposed are gradually inclined backward.

4. The refrigerator of claim 3 , further comprising:

a first gasket disposed around an edge of the outlet of the guide duct; and

a second gasket disposed around an edge of the inlet of the discharge duct and closely attached to the first gasket when the second door is closed.

5. The refrigerator of claim 3 , further comprising:

a communication hole passing through the partition wall and connect the ice making room to the storage room; and

a damper provided in the communication hole.

6. The refrigerator of claim 3 , wherein the opening is partitioned into an opening defining a front surface of the ice making room and an opening defining a front surface of the storage room by the partition wall.

7. The refrigerator of claim 6 , further comprising an ice making room door rotatably connected to an edge of the opening to define the front surface of the ice making room.

8. The refrigerator of claim 2 , wherein, when the second door is closed, a rear surface of the dispenser is accommodated in the storage room.

9. The refrigerator of claim 2 , further comprising:

an opening provided in a rear surface of the housing defining the storage room; and

a cover blocking the opening.

10. The refrigerator of claim 1 , further comprising:

an ice maker accommodated in the ice making room; and

an ice bin accommodated in the ice making room and disposed below the ice maker,

wherein an ice discharge hole is defined in a bottom of the ice bin to communicate with an inlet of the guide duct, and

an ice discharged to the ice discharge hole is discharged to the dispenser through the guide duct and the discharge duct.

11. The refrigerator of claim 1 , further comprising a sealing member disposed around a back surface of the second door and closely attached to an edge of the opening when the second door is closed.

12. The refrigerator of claim 1 , further comprising:

a first door hinge unit rotatably connecting the first door to the cabinet; and

a second door hinge unit rotatably connecting the second door to a front surface of the first door.
