Refrigerated case with ventilated glazed frame

In a refrigerator display cabinet including a refrigerated chamber having at least one transparent display window, a cooling system for cooling said refrigerated chamber and including a condenser and a compressor positioned below said refrigerated chamber and means for drawing exterior air through said condenser to thereby warm said air and then directing said warm air to said compressor, and means for preventing condensation from forming on said display window, the improvement wherein said condensation preventing means comprises:

• deflector means for diverting a portion only of the flow of warm air from said condenser to said compressor;
• duct means for receiving and conveying the diverted portion of said warm air and for discharging said diverted portion in a direction to pass across the outer surface of said display window;
• said duct means comprising a first duct extending horizontally from said deflector means above said compressor, the horizontal dimension of said first duct, in a direction transverse to the direction of air flow from said condenser to said compressor, progressively decreasing in a direction away from said deflector means, and said first duct opening laterally along one entire side thereof extending transverse to said horizontal dimension;
• and
• said duct means further comprising a second duct connected to and extending upwardly from said side of said first duct and opening in a direction toward said outer surface of said display window;
• whereby said diverted portion of said warm air passes horizontally through said first duct above said compressor and then passes upwardly through said second duct and is discharged therefrom across said outer surface of said display window.
