Patent ID: 8438872

Claim:
A refrigerator comprising: a refrigerator body; a refrigerating compartment defined at a first portion of the refrigerator body; a freezing compartment defined at a second portion of the refrigerator body, the second portion of the refrigerator body being different than the first portion of the refrigerator body and the freezing compartment being separated from the refrigerating compartment by one or more walls; at least one evaporator configured to cool air used in regulating operating temperatures in the refrigerating compartment and the freezing compartment that differ, with the freezing compartment having an operating temperature that is lower than an operating temperature of the refrigerating compartment; a refrigerating compartment door that is configured to open and close at least a portion of the refrigerating compartment; a freezing compartment door that is configured to open and close at least a portion of the freezing compartment; an ice compartment positioned at the refrigerating compartment door and configured to receive cool air from the freezing compartment; one or more ducts defining a first flow path configured to circulate cool air between the freezing compartment and the ice compartment; one or more ducts defining a second flow path configured to circulate cool air between the freezing compartment, the ice compartment, and the refrigerating compartment; an ice level sensor configured to detect a level of ice within the ice compartment; and a unit positioned at the second flow path and configured to control air flow along at least a portion of the second flow path based on the level of ice within the ice compartment.
