A method of controlling a dishwasher includes washing an object accommodated inside a tub by spraying water and detergent onto the object, rinsing the object by spraying water onto the object, drying the object by removing moisture adhered to the object, detecting an amount of a rinsing agent, comparing the detected amount of the rinsing agent to a predetermined amount, based on the comparison, determining whether the detected amount of the rinsing agent is less than the predetermined amount, and increasing at least one of a temperature of water to be supplied in the rinsing or a drying time in the drying based on determining that the detected amount of the rinsing agent is less than the predetermined amount.

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 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 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.

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.

An automated cleaning machine may include one or more short cleaning cycles in which the duration of a cleaning cycle is shortened relative to the duration of a default cleaning cycle. During a short cleaning cycle, other cleaning cycle parameters may also be adjusted to ensure that the articles subjected to the short cleaning cycle are adequately cleaned and sanitized. For example, the wash temperature, rinse temperature, and/or cleaning product amounts or concentrations, may be adjusted to account for the shortened duration of the cleaning cycle. The automated cleaning machine may further include one or more short cycle mode(s) during which short cleaning cycle parameters are used and one or more default cycle mode(s) during which default cleaning cycle parameters are used.

A conveyor warewasher includes at least one washing zone, at least one rinsing zone and a conveyor apparatus. A camera system is configured in order to capture at least one image of an portion of the conveyor apparatus continuously or at predetermined or determinable times and/or events. An image processing device is associated with the camera system and is configured to determine a position, orientation and/or alignment of washware items present in the at least one captured image. An evaluation device is further provided that is adapted to determine based on the determined position, orientation, and/or alignment of the washware items whether, at the time of the image capture, washware items are present in the portion of the conveyor apparatus (2) that: i) are transported incorrectly oriented by the conveyor apparatus (2); and/or ii) are transported misaligned by the conveyor apparatus.

The present disclosure relates to a dishmachine that includes at least two tanks and methods of using the tanks to isolate, substantially isolate, or incrementally isolate different chemistries from each other during a cycle. The disclosed dishmachine design and method allows for the use of two different, and potentially incompatible, reactive, or offsetting chemistries to be used in the same dishmachine cycle.

Disclosed herein is a dishwasher including a main body provided with an open hole and a washing tub; a door configured to open or close the open hole; a door opening/closing member configured to open or close the open hole; an air curtain disposed in the main body, to operate a fan such that ambient air is sucked and the sucked air is discharged; a detector configured to detect information of the fan; and a controller configured to diagnose the failure of the fan based on the detected information of the fan, to control an operation of the door opening/closing member such that the door is opened at a predetermined open time and an open time of the door is delayed when the fan is a failure state, and to control an operation of the fan when the fan is a normal state during a drying operation.
