Removal of heat and water vapor from commercial dishwashing machines
First Claim
1. A dishwashing machine that can be cooled after completing one or more cycles, said machine using water of elevated temperature, said machine producing a hot humid atmosphere, the machine comprising:
- (i) a machine enclosure comprising at least one inlet in fluid communication between the machine interior and the machine exterior, and (ii) extraction means comprising a housing comprising a water jet with a spray nozzle, and at least one conduit in fluid communication between the machine enclosure interior and the housing, the spray nozzle providing a water spray effective to create a zone of reduced pressure within the housing for removing the hot humid atmosphere from within the machine enclosure through the conduit, while causing entry of fresh air into the machine through the inlet.

Abstract
A water-driven jet or venturi extraction means is used to remove, capture and cool the hot, highly humid air created within commercial dishwashers during a wash rinse or sanitization cycle. A cold water spray is used to create a pressure reduction zone which serves to draw in hot, highly humid air from the dishwasher. Water vapor cools and condenses on contact with the cold water spray within the venturi. The invention also serves to help vent the dishwasher. Cool, fresh air is drawn into the dishwasher while the hot air is drawn into the venturi.
