A dishwasher (1) in the form of a commercial utensil washer or dishwasher which is designed as a batch dishwasher and is realized as a hood-type dishwasher, wherein the dishwasher (1) has a treatment chamber (2) with at least one wash system which is designed as a recirculation system, wherein the treatment chamber (2) has a first treatment zone (6) and at least one further, second treatment zone (7), wherein items of washware can be treated independently of one another and at least temporarily at the same time in the first and in the at least one second treatment zone (6, 7).

Disclosed is a dishwasher ejecting wash water containing microbubbles. The dishwasher according to an embodiment includes a tub accommodating dishes therein, a plurality of wash arms spraying wash water into the tub, a bubble nozzle ejecting wash water containing microbubbles to the bottom of the tub, a sump disposed below the bottom of the tub and collecting wash water therein, a wash pump pumping wash water collected in the sump, a channel-switching unit supplying wash water pumped by the wash pump to at least one of the plurality of wash arms, and a bubble module generating microbubbles in wash water pumped by the wash pump and supplying the wash water containing microbubbles to the bubble nozzle, and a controller operates the wash pump and controls the channel-switching unit and the bubble module to spray wash water through at least one of the plurality of wash arms and simultaneously to eject wash water through the bubble nozzle.

A method and a dishwasher utilize a dock detection system to determine when a connector of a spray device is docked to a docking port provided on a manifold of the dishwasher. A dock detector is coupled to the docking port and is electrically coupled to a controller of the dishwasher through electrical conductors that extend along the manifold, thereby enabling a dishwasher controller to detect when spray devices are coupled to the manifold, e.g., to optimize a wash cycle to use a particular spray device docked to the docking port.

The invention relates to a dishwasher in the form of a commercial utensil washer or dishwasher which is designed as a batch dishwasher and is realized as a hood-type dishwasher, wherein the dishwasher has a treatment chamber with at least one wash system which is designed as a recirculation system, wherein the treatment chamber has a first treatment zone and at least one further, second treatment zone, wherein items of washware can be treated independently of one another and at least temporarily at the same time in the first and in the at least one second treatment zone.

A dishwasher and silverware basket therefor include an interior sprayer integrated into the silverware basket and capable of directing a spray of fluid within one or more compartments of the silverware basket to assist in cleaning utensils such as silverware, cutlery, etc. housed within the silverware basket.

A dishwasher including a tub forming a washing chamber; a drying device disposed outside of the tub and including an inlet through which air from the washing chamber is introduceable, a flow channel in which air from the washing chamber introduced through the inlet flows, a fan that is operable to cause air from the washing chamber to be introduced through the inlet to flow in the flow channel, a heater in the flow channel to heat air in the flow channel, an outlet through which air in the flow channel is discharged to the washing chamber, and a temperature sensor between the heater and the outlet; and at least one processor configured to operate the fan based on a start of a drying cycle and to determine an initial operation time point of the heater during the drying cycle based on temperature detected by the temperature sensor.

Proposed is ultrasonic spoon washing apparatus and method, which use ultrasonic waves generated by one or more ultrasonic oscillators provided on a vertical side wall of polygonal surfaces of a wash tub, so that spoons contained in a spoon support part rotating forward/in reverse may very efficiently and conveniently be washed while the number of revolutions changes for each washing stage, the apparatus including: a frame body; the wash tub mounted inside the frame body; one or more ultrasonic oscillators provided on an outer side of the vertical side wall; a forward/reverse rotation support part including a support shaft and a rotation support pipe; a spoon support part including a holder and a spoon accommodation container; a rinsing water supply part configured to spray the rinsing water together with a rinsing aid; and a wastewater and foreign material discharge part configured to discharge, to the outside, wastewater and foreign materials.

A conveyor warewasher has at least one washing zone, at least one rinsing zone and a conveyor apparatus. A camera system is arranged above or below or to the side of the conveyor apparatus and is configured in order capture at least one image of a portion of the conveyor apparatus, preferably continuously or at predetermined or determinable times and/or events. An evaluation device is configured in order to evaluate and determine on the basis of the at least one image whether, at the time of the image capture, washware of the following washware category was present in the portion of the conveyor apparatus: reusable plasticware, in particular in the form of plastic trays, plastic mugs, plastic bowls, plastic covers for plastic bowls, and/or plastic plates.

A conveyor warewasher has at least one washing zone, at least one rinsing zone and a conveyor apparatus. A device for sensing a loading of the conveyor apparatus, which device is configured in order to determine, continuously or at predetermined or determinable times and/or events, a loading of the conveyor apparatus with washware. A control device is configured in order to, during a learning or observation phase over at least one observation period or over a plurality of observation periods each relating to a washing shift or a washing day of the conveyor warewasher or a portion thereof, determine a chronological profile of the loading of the conveyor apparatus with washware to be conveyed, wherein the control device is configured in order to deduce a pattern or a regularity based on the determined chronological profile of the loading of the conveyor apparatus with washware.
