Title: Refrigerated display cabinet with glass doors
Inventor: IBRAHIM FAYEZ F
IPC: A47F3/04
Filed: 1981-04-25
Abstract: The invention relates to a refrigerated display cabinet with a display area inside a cabinet housing and a movable door which covers the front access opening to the display area. The door comprises a frame in which two panes of glass are mounted with an air gap between them. A cooling-air conductor extends over the top, the bottom and the back of the cabinet housing. The cooling-air conductor has an outlet aperture and an inlet aperture at its opposite ends, which apertures are aligned with one another in such a way that air leaving the outlet aperture is directed onto the inlet aperture and taken up by the latter, as a result of which an air curtain is formed transversely over the access opening of the cabinet housing on a path located on the inside of the door. During the cooling cycle of the display cabinet, cooled air is circulated by the cooling-air conductor. Arranged inside the cooling-air conductor is a cooling device which maintains a cooled air strip or a cooled air curtain transversely over the front access opening of the cabinet housing. In order to avoid any accumulation of condensation between the panes of glass in the door, when the door is closed a stream of ambient air is maintained between the panes of glass. During the defrosting cycle, the cooling device is switched off and the door covering the front access opening is opened slightly. Ambient air is then sucked into the cooling-air conductor and circulated by the latter. This ambient air serves for defrosting the cooling device and the interior of the cooling-air conductor. <IMAGE>
