Abstract

A batch-type warewash machine includes a chamber for receiving wares to be cleaned, the chamber having a chamber access opening and a single spray zone, with at least one spray system for spraying liquid onto wares in the single spray zone. A door is movable between a closed position covering the chamber access opening and an open position away from the chamber access opening to allow wares to be moved in and out of the chamber. A curtain structure is mounted on the machine, the curtain structure located behind the door when the door is in the closed position. The curtain structure remains in position and at least partially covers the chamber access opening when the door is in the open position so as to retain hot moist air within the chamber when the door is moved to the open position upon completion of a ware cleaning cycle.
