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 dishwasher can be included in a home network and can be utilized to complete a cycle of operation. The dishwasher includes a controller capable of automatically determining treating at least one cycle parameter based on the communication of at least one aspect of a recipe. The at least one aspect of a recipe can be wirelessly provided to a computer system that is in communication with the dishwasher. The computer system can be the controller or any known computer system in communication with the dishwasher.

A dishwasher utilizes one or more sensors capable of detecting when a rack is at an operative position at which the rack is positioned within the wash tub during washing and/or an extended position at which at least a portion of the rack is extended beyond the wash tub for loading or unloading of utensils, thereby allowing image captures by a camera to be timed relative to the movement of the rack into, between and/or away from the operative and/or extended positions.

A method of controlling a dishwasher including a tub, at least one spray nozzle, a rack, and a microphone, includes: spraying, by the at least one spray nozzle, washing water while the at least one spray nozzle is rotating, analyzing a characteristic of a sound wave input to the microphone, the sound wave being generated based on the washing water colliding with one or more washing targets in the tub, determining whether a washing target made of a set material is present among the one or more washing targets based on the analyzed characteristic, determining, based on determining that the washing target made of the set material is present, a location in which the washing target made of the set material is present according to the analyzed characteristic, and reducing an amount of impact applied to the washing target made of the set material by the washing water.

A domestic laundry-washing appliance including an optical measuring device for obtaining measured values which are representative of a spectral transmission signature of a washing liquid used during operation of the laundry-washing appliance for cleaning textiles, and a control device which is adapted to categorise a cleaning agent contained in the washing liquid in respect of its chemical properties on the basis of the spectral transmission signature obtained, and to control the operation of the laundry-washing appliance in dependence on the categorisation result. The categorisation result can indicate, for example, a distinction between a heavy-duty detergent containing bleach and another bleach-free detergent.

The present disclosure concerns a method for operating or controlling an operation of a household appliance (100, 300) performed by at least one device (100, 200, 300, 400). The method includes: obtaining external information representative of at least one external given situation outside the household appliance (100, 300); and operating or controlling an operation of the household appliance (100, 300) at least taking into account the external information obtained. In addition, the present disclosure concerns a device and a system for performing such a method.

A dishwasher and method for operating the same utilize a rack-mounted rotatable conduit incorporating a keyed connector disposed at an end thereof and configured to mate with a rotatable docking port disposed on a wall of a wash tub at a predetermined angular relationship when the rack is in the washing position such that rotation of the rotatable docking port causes rotation of the rotatable conduit.

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 (1) in the form of an industrial dishwasher which is designed in the form of a box-type dishwasher, configured in the form of a hood-type dishwasher and has a treatment chamber (5) with at least one wash system designed in the form of a recirculation system. In order to make it possible to optimise the actual potential capacity of the dishwasher, to be precise while at the same time easing the burden on the operating staff, the dishwasher (1) is assigned a loading/unloading apparatus (4, 4) for preferably optionally automatically loading the treatment chamber (5) with washware (9) and/or for preferably optionally automatically unloading washware (9) from the treatment chamber (5).

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.
