A portable handheld submersible ultrasonic cleaning device has a generally elongate body defining proximal and distal ends, a power supply and an ultrasonic transducer powered thereby, wherein the distal end exposes the ultrasonic transducer to agitate surrounding water when the base is submerged in the water use. A propeller device comprising a propeller may force the water across the ultrasonic transducer. When cleaning, the device may be held with the distal end thereof submerged for enhanced cleaning and removing surface contaminants such as dust, dirt, oil, pigments, bacteria and the like. The device may be stood upright upon the base on the floor of a container for hands-free application of ultrasound whilst cleaning.

A system (10) for loading different conveying tracks (2, 3, 4) of at least one in particular commercial conveyor dishwasher (1, 1′). The system (10) includes a feed conveyor belt (11) for delivering washware (9a, 9b, 9c) to loading regions of the at least one conveyor dishwasher (1, 1′). The system (10) further includes a sorting arrangement for sorting the washware (9a, 9b, 9c) delivered to the loading regions of the at least one conveyor dishwasher (1, 1′) via the feed conveyor belt (11) according to previously defined or definable washware groups. The sorting arrangement is associated with at least one loading arrangement (13a, 13b, 13c) for automatically loading the different conveying tracks of the at least one conveyor dishwasher (1, 1′) with washware (9a, 9b, 9c) of one of the previously defined or definable washware groups.

A free-standing Energy Recovery System enables sanitary recovery of thermal energy with heat transfer from hot waste effluent to incoming domestic water. The source of the effluent may, for example, be conventional commercial ware-washing, clothes washing equipment, pasteurization and other industrial processes.

A washing system for determining an operating state of a dishwasher comprises a dishwasher, in particular wherein the dishwasher comprises a dishwasher interface, a dispenser unit, in particular wherein the dispenser unit comprises a dispenser interface, wherein the dispenser unit is connected to the dishwasher for dosing a detergent to the dishwasher, a logic unit, in particular wherein the logic unit is connectable to the dishwasher interface and the dispenser interface, and a current sensor for measuring an electrical current consumed by the dishwasher, wherein the current sensor is connected to the logic unit. By replacing costly water meters by a current sensor, the cost efficiency of the washing system may be increased. In addition, the assembling and maintenance effort of the washing system may be reduced.

A dishwashing appliance may include a cabinet, a tub, a spray assembly, a drain pump, a turbidity sensor, and a controller. The tub may be positioned within the cabinet and defining a wash chamber for receipt of articles for washing. The spray assembly may be positioned within the wash chamber. The drain pump may be in fluid communication with the wash chamber. The turbidity sensor may be mounted within the cabinet. The controller may be in operative communication with the turbidity sensor and the drain pump. The controller may be configured to initiate a wash operation. The wash operation may include initiating a rinse cycle, obtaining an image of the wash chamber, determining calibration viability for the turbidity sensor based on the obtained image, and adjusting a calibration state of the turbidity sensor based on the determined calibration viability.

A warewash machine for washing wares includes a chamber for receiving wares, the chamber having an inlet side, an outlet side, multiple spray zones between the inlet side and the outlet side, and a conveyor arrangement for moving wares along a conveyance path through the multiple spray zones in a ware travel direction. A prescrapping zone is located toward the inlet side of the chamber, the prescrapping zone having a blow-off system comprising a plurality of prescrapping nozzles and a compressed air feed line for delivering compressed air to the prescrapping nozzles.

A system and method for cleaning a reusable dish, comprising: picking a dirty dish from a load module disposed to contain at least one dirty dish with a robotic arm, wherein said dirty dish is stained with material that needs to be removed prior to reuse; transporting said dirty dish from said load module to a wash module with said robotic arm; cleaning said dirty dish in said wash module having the means to transform said dirty dish into a clean dish, wherein said clean dish does not exhibit any material that needs to be removed prior to reuse; transporting said clean dish from said wash module to a store module with said robotic arm; and dropping off said clean dish in said store module, wherein said store module is disposed to contain at least one clean dish, whereby each dirty dish is cleaned thoroughly and efficiently with individual attention in real time.

A system includes a dishwasher having a receptacle for items to be washed, an image capturing facility configured to capture an image of the receptacle of the dishwasher for items to be washed, and an image processing facility configured to determine in dependence upon the captured image a map of an arrangement of the items to be washed. The map includes a division of the receptacle into a number of regions, with each region having a predetermined arrangement of items to be washed from a number of predetermined arrangements of items to be washed. An allocation unit determines a cleaning matrix including an allocation of a treatment specification to each of the regions in the map, and outputs the cleaning matrix. A control apparatus executes a wash program based on the cleaning matrix.

A computer program product for a robot which includes a computer for operating a household dishwasher having a plurality of treatment programs is disclosed. The computer program product includes a non-transitory computer readable medium having commands which when the computer program product is run by the computer prompt the robot to carry out the steps of loading dishwasher skills which are specific to the household dishwasher from a storage device, and carrying out at least some of the loaded dishwasher skills in order to operate the household dishwasher.

A dishwasher for treating dishes according to an automatic cycle of operation having a tub that at least partially defines a treating chamber, a slidable dish holder, an electricity-consuming component having a rechargeable battery, and a battery charging system to recharge the rechargeable battery of the electricity-consuming component when the dish holder is in the treating position.
