Image-based object sensing is utilized in a dishwasher to configure a wash cycle and/or perform other operations in the dishwasher.

A beverage container washing system may be used for rapid washing and/or sanitizing of beverage containers, e.g., for use in a retail environment to wash and/or sanitize customer-provided beverage containers prior to filling the beverage containers with purchased beverages, among other applications. Separate entrance and exit openings may be provided in some instances to minimize employee interaction with unwashed customer beverage containers.

A prewashing system includes a dish recognizing unit that recognizes a dish that is an object of prewashing executed prior to main washing, a first prewashing unit that performs prewashing of the dish that is the object of prewashing by a flow of water, a second prewashing unit that performs prewashing of the dish that is the object of prewashing by a washing tool, a prewashing method deciding unit that decides a prewashing method using at least one of the first prewashing unit and the second prewashing unit, on the basis of a form of the dish that is the object of prewashing, which is recognized by the dish recognizing unit, and a prewashing executing unit that executes prewashing of the dish that is the object of prewashing, by the prewashing method decided by the prewashing method deciding unit.

A system includes a dishwasher including a dishwasher cavity, a spray facility for applying washing liquor and/or fresh water to dishes accommodated in the dishwasher cavity, a drive facility for actively driving the spray facility, and a control apparatus for activating the drive facility depending on a control signal. An input unit detects a user input for moving the spray facility, and a generation unit generates the control signal depending on the user input detected.

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.

The present disclosure relates to a dishwasher. The dishwasher according to an embodiment comprises: a tub having a washing room, in which an object to be washed is accommodated, formed therein; a nozzle which is arranged in the washing room and sprays washing water to the object to be washed, and includes a magnetic body at one end thereof; a coil which his formed to surround a region corresponding to a movable range of the nozzle, and through which an electric current flows according to the rotation of the nozzle; and a controller which controls an operation of the nozzle according to an operation command, and determines an operating status of the nozzle on the basis of a value of the voltage generated in the coil.

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.

Systems and/or methods for the monitoring and/or control of thermal sanitization in automated cleaning machines are described. A cleaning machine controller may predict a number of heat unit equivalents that will be delivered during a cleaning process based on a sump temperature difference (i.e., a change in the temperature of the cleaning solution in the sump) experienced at or near the beginning of the cleaning process. One or more cleaning process parameters may be adjusted and/or controlled based on the sump temperature difference in order to ensure that a target number of heat unit equivalents are delivered in order to achieve thermal sanitization of the wares subjected to the cleaning process.

A dishwasher and method utilize an imaging system to perform various diagnostic operations within the dishwasher, including one or more of level sensing, filter cleaning, wash tub rinse down, foam detection, imaging system cleaning, and remote viewing. A controller may clean a filter by controllably-redirecting a controllably-movable sprayer to spray fluid onto the filter.

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.
