Abstract

A refrigerator includes a refrigerator cabinet, a refrigerator compartment disposed within the refrigerator cabinet, a freezer compartment disposed within the refrigerator cabinet, and a battery. There is at least one fan disposed within the refrigerator cabinet and electrically connected to the battery. The battery powers the at least one fan during a power outage to thereby circulate air from the freezer compartment to the refrigerator compartment. The at least one fan may be a direct current operated fan. The refrigerator may also include an inverter and the at least one fan may then be an alternating current operated fan electrically connected to the inverter. The battery may be disposed within the refrigerator cabinet or may be external to the refrigerator cabinet.
