Abstract: An apparatus for the evacuation of warm, moist air or vapor from a dishwasher cabinet or other washing machine interior. A centrifugal fan draws the hot air and water vapor out of the washing cavity through a flue riser and discharges it into a cooling chamber with one or more cooling spray nozzles. The cooling spray nozzles spray a fine mist of cold water into the stream of heated air and vapor, and may spray at angle to the flow of the stream of heated air and vapor. As the heated air and vapor from the dishwasher and the cooling spray mix, heat is transferred from the heated air and vapor to the cold water or mist being sprayed into the air stream. This reduces the temperature of the vapors and air that was extracted from the dishwasher. As the temperature is reduced, the water vapors condense and form droplets which accumulate on the sides and bottom of the cooling flue.

Abstract: An apparatus and system for detecting the delivery or nondelivery of a cleaning and sanitizing agent or chemical in automated dishwashers, warewashers, and laundry machines. A detector comprising one or more sensors or two or more electrical electrodes are positioned outside the ends of the delivery tube or tubes for the sanitizing agent or chemical. As the sanitizing agent or chemical liquid is released from the delivery tube or tubes, the liquid forms a stream of flow through the air. The flow passes within sensing range of the sensor or sensors, or encompasses the electrical electrodes thereby completing an electrical circuit. When the sensor detects the flow and the sensor is activated, or the circuit completes, a control unit prevents an alarm from sounding.
