ABSTRACT:
A food receptacle for a refrigerator freezer compartment for fast-thawing and fast freezing food by the use of a concavo-convex heat energy reflective damper pivotally mounted in an air passage of the receptacle which communicates with an opening in the refrigerated air duct of the compartment. A high energy radiating lamp is located on the pivotal axis of the damper such that a manual control pivots the damper to a first evaporator defrost position closing the passage with the damper operative to direct heat energy from the lamp via reflective surfaces in the duct to the refrigerator cooling coil. The damper upon being pivoted to a second position, opens the passage and cooperates with the duct reflective surfaces to circulate below freezing air through the receptacle to fast freeze food therein. The damper, upon being pivoted to a third position, closes the passage and reflects heat energy from the lamp into the receptacle to fast-thaw food therein.
