Patent ID: 8707728

Claim:
A refrigerator comprising: a refrigerator cabinet; a mullion wall dividing the refrigerator cabinet into a plurality of storage cavities; a refrigerating chamber defined as one of the plurality of storage cavities, the refrigerating chamber being configured to maintain a refrigerating temperature that is above freezing; a refrigerating chamber door configured to open and close at least a portion of the refrigerating chamber; a freezing chamber defined as another of the plurality of storage cavities, the freezing chamber being configured to maintain a temperature that is below freezing and being positioned below the refrigerating chamber; a freezing chamber door configured to open and close at least a portion of the freezing chamber; an ice compartment located on the refrigerating chamber door and configured to maintain a temperature that is below freezing, the ice compartment including: at least one insulating wall; and an ice container configured to store ice; at least one evaporator mounted in the freezing chamber; a cold air supply duct extending from the freezing chamber to the ice compartment and configured to, when the refrigerating chamber door is closed, supply air cooled to a freezing temperature by the evaporator to the ice compartment; a dispenser positioned on the refrigerating chamber door and configured to dispense ice stored in the ice container; a return duct having a first end in communication with the ice compartment, having a second end in communication with the freezing chamber, and being configured to, when the refrigerating chamber door is closed, enable return of air from the ice compartment to the at least one evaporator mounted in the freezing chamber; and a gasket located at a portion of the return duct that separates when the refrigerating chamber door opens, the gasket being configured to prevent leakage of air from the return duct at the portion of the return duct when the refrigerating chamber door is closed, wherein a first portion at which the cold air supply duct establishes communication with the ice compartment is spaced apart in a vertical direction from a second portion at which the first end of the return duct establishes communication with the ice compartment, and the ice container is located at a third portion that is between the first portion and the second portion such that air flowing from the cold air supply duct to the return duct passes over the ice container in the vertical direction.
