Abstract: A vapor extraction apparatus for a warewasher includes a housing in which a water-steam separation media is mounted. The housing has an inlet for receiving hot, humid air, water vapor and steam from a washing chamber of a warewasher, a blower for drawing the hot, humid air, water vapor and steam into the housing across the water-steam separation media, and an outlet for air dehumidified and cooled by the water-steam separation media to exit the housing. A duct connects the inlet to a washing chamber of a warewasher, and a bypass damper can be connected to the duct. The bypass damper is operable in a first position to permit air, water vapor and steam from the washing chamber to be drawn into the housing and in a second position to permit ambient room air to be drawn into the housing for cooling the vapor extraction apparatus.

Abstract: A vapor extraction apparatus for a warewasher includes a closed-wall, hollow housing in which a water-steam separation media is mounted above a water-tight base connecting to drainage piping. The housing also includes an inlet for receiving a flow of hot, humid air, water vapor and steam from a washing chamber of a warewasher, a blower located within the housing for drawing the hot, humid air, water vapor and steam into the housing and across the water-steam separation media, and an outlet adjacent the blower for air flowing through the housing and being dehumidified and cooled by the water-steam separation media to exit the housing to ambient room air. A duct can be used to connect the inlet to a washing chamber of a warewasher, and a bypass damper can be connected to the duct.

Abstract: A sensor assembly is provided for determining the presence or lack thereof of a removable dishware rack within a chamber of a warewasher. The sensor assembly includes a mounting bracket within the chamber of the warewasher at a location beyond a path of travel of the dishware rack and a pivot arm connected to the mounting bracket. The pivot arm is moveable relative to the mounting bracket between a normal upright position and an angularly deflected position in which the pivot arm is pivoted in an outward direction relative to the path of travel of the rack. A magnet is mounted on the pivot arm and an actuator extends forwardly from the pivot arm within the path of travel of the dishware rack within the chamber when the pivot arm is in the normal upright position. The pivot arm pivots to the deflected position when the dishware rack is properly loaded within the chamber and engages the actuator. A magnetic proximity switch is mounted on the warewasher for sensing the magnet.
