WAREWASHER WITH ULTRASONIC-BASED WARE DETECTION

A warewash machine includes a housing defining a chamber for receiving wares, the chamber having at least one spray zone, a wash spray system for spraying wash liquid onto wares and a rinse spray system for spraying rinse liquid onto wares. At least one ultrasonic transducer is located for detecting wares feeding into the chamber and/or for detecting wares within the chamber. A controller is associated with the ultrasonic transducer and configured to identify one or more of ware location, ware movement, ware size, ware shape and/or ware material based upon outputs from the at least one ultrasonic transducer. The controller is further configured to control at least one operating parameter of the machine based at least in part upon identified ware location, identified ware movement, identified ware size, identified ware shape and/or identified ware material. 种洗碗机包括壳体，壳体限定用于接收器皿的腔室，该腔室具有至少个喷射区、用于将洗涤液体喷射到器皿上的洗涤喷射系统、以及用于将漂洗液体喷射到器皿上的漂洗喷射系统。设置至少个超声换能器，用于检测送入腔室的器皿和/或用于检测腔室内部的器皿。控制器与该超声换能器相关联，并且被配置为基于来自至少个超声换能器的输出，来识别
