The refrigerator door includes an ice compartment, an ice maker in the ice compartment, the ice maker generating ice cubes, an ice bin storing the ice cubes generated in the ice maker, and a cool air duct guiding cool air to the ice maker.
1. A refrigerator comprising:
a cabinet having a refrigerator compartment;
a main body supply duct extending along a side wall of the cabinet;
a main body return duct extending along the side wall of the cabinet; and
a door configured to open and close the refrigerator compartment, wherein the door comprises:
an ice compartment;
an ice making assembly, the ice making assembly including:
an ice maker disposed within the ice compartment and configured to generate ice cubes; and
an ice bin configured to store the ice cubes generated in the ice maker;
a door supply duct installed in a side portion of the door, an inlet of the door supply duct connected to an outlet of the main body supply duct when the door is closed, and an outlet of the door supply duct connected to a side surface of a wall defining the ice compartment;
a door return duct installed in the side portion of the door below the door supply duct, an inlet of the door return duct connected to the side surface of the wall defining the ice compartment, and an outlet of the door return duct connected to an inlet of the main body return duct when the door is closed;
a cool air duct extending from the wall defining the ice compartment to a position above the ice maker to downwardly guide cool air to an upper portion of the ice maker, the cool air duct including:
a first side surface;
a second side surface facing the first side surface;
a bottom surface defined from a lower end of the first side surface to a lower end of the second side surface;
a cool air inflow hole located at the first side surface and arranged in fluid communication with the outlet of the door supply duct; and
a plurality of cool air discharge holes located at the bottom surface and the second side surface, the plurality of cool air discharge holes located above the ice maker;
a cover configured to cover the ice maker to prevent water supplied to the ice maker from overflowing; and
a cool air guide extending upwardly from an upper end of the cover, the cool air guide configured to guide the cool air discharged from the plurality of cool air discharge holes of the cool air duct to the ice maker,
wherein a vertical section area of a cool air passage within the cool air duct is reduced from the first side surface to the second side surface to uniformly supply the cool air throughout an upper portion of the ice maker.
2. The refrigerator according to claim 1 , wherein
the plurality of cool air discharge holes are disposed above the cool air guide to uniformly supply the cool air to the ice maker.
3. The refrigerator according to claim 1 , wherein the cover is rounded, and
the cool air guide extends vertically from the cover.
4. The refrigerator according to claim 1 , further comprising:
a driving source generating a power to automatically rotate the ice maker; and
a gear box transmitting the power of the driving source to the ice maker.
5. The refrigerator according to claim 1 , further comprising a water guide part disposed between the cool air duct and a door liner defining the ice compartment, so as to guide water to the ice maker.
