A dishwasher (1), in particular a commercial dishwasher (1), which is in the form of a box-type dishwasher and has a treatment chamber (2) which can be closed and in which washware can be treated in accordance with a predefined or predefinable treatment program, wherein a washware detector apparatus (51) is designed to detect the type of washware to be, wherein the washware detector apparatus (51) has an optical identification system, which is oriented toward the washware to be treated, and an evaluation device, wherein the optical identification system is designed to record at least a portion of the light reflected by the washware to be treated as a reflection image, and wherein the evaluation device is designed to automatically distinguish between different types of washware on the basis of the recorded reflection image, wherein the extent of the reflection provides information about the type of washware.

A dishwasher may include a washing chamber and a wash arm arrangement having a wash arm rotatably arranged in the washing chamber, and a satellite spray device arranged on the wash arm. The dishwasher may include at least one sensor configured to sense a rotational position of the wash arm and a control unit configured to monitor consecutive sensed rotational positions of the wash arm. The control unit may be configured to calculate a rotational speed of the wash arm based on an elapsed time and a rotational distance between two sensed rotational positions, and may be configured to estimate a current rotational position of the wash arm based on an elapsed time since a previously sensed rotational position and the calculated rotational speed. The control unit may adapt the pumping intensity of a pump of the dishwasher based on the estimated current rotational position of the wash arm.

A dishwashing machine is provided to include at least one spray part spraying washing water, a vane provided to be movable and deflecting the sprayed washing water, a rack accommodating tableware to be washed by the washing water deflected by the vane, a detection part detecting the tableware accommodated in the rack, and a controller generating position information with respect to the tableware detected by the detection part and controlling an operation of at least one of the at least one spray part and the vane based on the generated position information.

A conveyor dishwasher includes at least one wash zone and at least one final rinse zone, wherein the at least one wash zone is designed to spray wash liquid, wherein the wash liquid is, at least proportionally, liquid which has already been used for final rinsing in the at least one final rinse zone and to which a wash chemical is added in a metered manner or is fresh water to which a wash chemical is added in a metered manner, wherein the conveyor dishwasher has a metering pump for adding the wash chemical in a metered manner to the liquid to be sprayed in the at least one wash zone, and wherein a controller is associated with the conveyor dishwasher in order to actuate the metering pump and a wash pump or final rinse pump of the dishwasher.

An appliance, as provided herein, can include a direct current load and a current sensing circuit that can be coupled to the direct current load. The current sensing circuit can be configured to collect electrical data corresponding to the direct current load. The appliance can include one or more processors that can be coupled to the current sensing circuit. The one or more processors can be configured to identify at least one attribute of the direct current load based, at least in part, on the electrical data and activate at least one operation of the direct current load or the appliance based, at least in part, on identification of the at least one attribute of the direct current load.

A light sensor device is disclosed for installation in a heat-using domestic electrical appliance such as, for example, a washing machine or a dishwasher and permits the implementation of a touch-free operating function, for example an automatic door opening function. The light sensor device includes in some embodiments: a window element which is formed of light-permeable material and is arranged with space on a first window side for hand movements; a first light source arrangement arranged to radiate visible light into the window element; a second light source arrangement which is arranged to radiate infrared light through the window element from a second window side opposite the first window side; and a photodetector arrangement which is sensitive to infrared light of the second light source arrangement and is arranged on the second window side, for detecting infrared light which strikes the photodetector arrangement from the window element.

Disclosed is a cleaning device for cleaning washware. The cleaning device may be a conveyor dishwasher. The cleaning device has at least one cleaning chamber and at least one transportation device. The transportation device transports the washware through the cleaning chamber in a transportation direction. The cleaning device has at least one final-rinse nozzle system for applying at least one final-rinse fluid, in particular fresh water, to the washware. The final-rinse nozzle system has at least two final-rinse nozzle units which are arranged in different positions transverse to the transportation direction. The final-rinse nozzle units can be switched independently of one another in order to apply the final-rinse fluid to the washware in the different positions independently of one another.

An air jet generator according to an embodiment of the present invention includes: an impeller which applies centrifugal force to washing water flowing in a forward direction; a decompression portion which decreases a pressure of the washing water that flows; an air suction portion which is opened to allow air to flow into the decompression portion; a pressing portion which increases pressure so as to crush the air introduced from the air suction portion; an air tap which has a plurality of holes so as to crush the air contained in the washing water that passed through the pressing portion; and a reverse spray nozzle which sprays the washing water toward the air tap in a reverse direction.

A dish washer senses an amount of change in a level of a detergent via a floater that moves in a vertical direction based on the level of the detergent and a detergent level sensor that senses a location in the vertical direction of the floater, and effectively identifies a viscosity of the detergent stored in a detergent supply based on the amount of change in the level to simplify a structure, improve space utilization, and reduce a manufacturing cost by eliminating a separate electrode sensor or level sensor to identify the viscosity of the detergent.

A washing apparatus (e.g. a laundry washing machine, dishwasher, etc.) and method configure a wash cycle in part based on spectral data obtained from a spectrometer positioned with the washing apparatus and analyzed in a remote cloud service.
