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.

An on-demand glasswasher comprises a drive motor; a rotary conveyor connected to the drive motor; an ultrasonic sensor assembly positioned adjacent to the rotary conveyor; a microprocessor connected to the drive motor and the ultrasonic sensor assembly; and a memory device coupled to the microprocessor, the memory device storing processor-executable instructions which, when executed by the microprocessor, cause the microprocessor to receive, from the ultrasonic sensor assembly, ultrasonic signals; analyze the ultrasonic signals to detect the presence of one or more objects on the rotary conveyor; and responsive to detecting the presence of one or more objects on the rotary conveyor, perform operations to stop operation of the on-demand glasswasher.

A system includes a dishwasher including a washing chamber, a sensor unit designed to detect a time curve of at least one sensor signal of a washing liquor and to output the detected time curve of the at least one sensor signal, a memory unit designed to store the time curve of the at least one sensor signal, an ascertaining unit designed to ascertain a temporal functional value based on the time curve of the at least one sensor signal, and a control device designed to carry out a washing program for washing washware in the washing chamber of the dishwasher and to carry out a specified action as a function of the temporal functional value..

A system includes a dishwasher, an image capturing device designed to capture an image of washware arranged in the washing chamber, with the image including a plurality of sub-images, each of which having different spectral information of the washware. An illumination unit illuminates the washware in the washing chamber, and an image analysis unit receives the captured image from the image capturing device and to carry out a chemical analysis of soiling on the washware based on the plurality of sub-images of the received image and to ascertain a dirt characteristic of soiling as a result of the chemical analysis. A control device carries out a washing program for washing the washware in the washing chamber. The control device receives the dirt characteristic from the image analysis unit and adapts the washing program for washing the washware as a function of the received dirt characteristic.

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 in one embodiment is provided with a spray arm, and the spray arm is provided individually with areas configured to spray water to a first spray area and a second spray area, and sprays water to the first spray area to entirely wash objects to be washed accommodated in the dishwasher and sprays water to the second spray area to wash objects to be washed with remaining contaminants by applying a great impact on the object to be washed with remaining contaminants.

A system and method for cleaning a dish, comprising: capturing at least one image of said dish using at least one camera; computing a bounding polygon for a dirty region in said image, wherein said dirty region is a region of said dish containing unwanted material that needs to be removed; computing a three dimensional representation of said bounding polygon by estimating three dimensional locations of multiple points within said bounding polygon; computing a spray pattern within said three dimensional representation of said bounding polygon such that the spray pattern substantially covers all regions of said three dimensional representation; and spraying a fluid on said dirty region of said dish with a nozzle, wherein said nozzle is reoriented or relocated such that said fluid reaches at least one location within said three dimensional representation of said bounding polygon according to said spray pattern, whereby dirty regions of said dish are targeted for a fast and efficient cleaning of said dish.

A washing and drying unit configured to perform at least one of washing, drying, and sterilizing, or any combination thereof includes at least one sensor configured to determine a dimension and/or shape of the object, a washing and/or sterilizing apparatus and a drying and/or sterilizing apparatus configured to direct at least one apparatus or spray of a washing and/or sterilizing or a drying and/or sterilizing fluid to the object, at least one robot arm connected to at least one of the apparatuses, and a controller operable to orient and move the at least one robot arm. A separate sterilization apparatus may be included and the sterilization may include using electrified water or water that has been exposed to ultraviolet light. The controller orients the at least one robot arm based on the dimension and/or shape determined by the at least one sensor.
