Title:
FOOD WARMING UNIT WITH HUMIDITY CONTROL
Document Type and Number:
WIPO Patent Application WO2001023809
Kind Code:
A3
Abstract:
A food warming cabinet (10) includes inner and outer spaced wall members (14,34), and a door (20) forming an internal compartment (12). A heated cable arrangement (30) is interposed between the outer and inner wall members and provides a source of heat to keep the food warm. Heat insulation (32) is disposed between the inner (14) and outer (34) wall members to support the heating cable arrangement and maintain the heat developed by the heating cable arrangement in the internal compartment. A solenoid valve (44) and a spray nozzle (42) project through the wall members for selectively delivering a spray film of water from an outside source to a drip pan (50). A controller (38) is associated with the internal compartment (12) for activating the solenoid valve (44) for a predetermined time in response to opening of the door (20), whereby evaporation of moisture from the heated food lost in the opening of the door is replenished by evaporation of the water film deposited in the drip pan.
