A dispensing device for a dishwasher and a dishwasher are provided. The dispensing device for the dishwasher has a liquid storage container, a pump body and a driving assembly. The liquid storage container stores liquid detergent. The pump body is mounted on the liquid storage container and has a pump head. The driving assembly operates to drive the pump head to pump the detergent in the liquid storage container into a washing chamber of the dishwasher.

A dishwasher includes an image-based detergent sensor that in some instances is configured to sense a type of detergent for use in optimizing a wash cycle based upon the type of detergent, and that in some instances is configured to direct one or more controllable sprayers to facilitate dissolution or mixing of detergent into a wash fluid during a wash cycle.

A metering device for metering and supplying media via a fluid line to at least one target apparatus, in particular to an industrial textile washing machine, wherein the metering device is connected to at least one container which is filled with a medium. The metering device has a control unit which, in order to carry out a metering process with the aid of at least one pump, causes a specific volume of medium to be removed from the container and a conveyance of this volume towards the target apparatus. The fluid line has at least one heating element and at least one temperature sensor connected to a measuring device, wherein, by way of the measuring device, with the aid of a measurement value output by the temperature sensor, information about a performed conveyance of the medium through the fluid line can be determined and transmitted to the control unit.

An auxiliary gray water supply device captures used wash water from a commercial warewashing machine for supply to a pre-rinse station without substantial modification of the commercial warewashing machine. The captured wash water and treatment agent are delivered to a pre-rinse station for pre-rinsing of dishes that will be washed within the commercial warewashing machine.

A dishwasher includes an image-based detergent sensor that in some instances is configured to sense a type of detergent for use in optimizing a wash cycle based upon the type of detergent, and that in some instances is configured to direct one or more controllable sprayers to facilitate dissolution or mixing of detergent into a wash fluid during a wash cycle.

System and method for dispensing product to a washing machine. A chemical dispensing system includes a system controller, machine interface, and pump controller that communicate through serial data buses. The system controller provides a user interface, retrieves washing machine status information from the machine interface, and issues product dispensing commands to the pump controller. The pump controller monitors pump status and dispenses product in response to commands from the system controller. The pump controller: (1) determines pump activation periods based on calibration data stored in a pump controller memory; (2) tracks pump usage and adjusts the activation period to compensate for pump wear as the pump ages; (3) disables the pump if conditions exists that preclude operating the pump; (4) monitors product levels, and (5) reports pump status to the system controller. Integral channels are included in the pump housing to provide stress relief to a squeeze tube.

A dishwasher has a liquid supply system with a first conduit portion through which the liquid passes, and an air supply system with a second conduit portion through which the air passes. The first conduit portion at least partially forms the second conduit portion to define a thermal transfer interface. A heating system includes a heating element provided on the thermal transfer interface. Activation of the heating element provides heat to both the liquid supply system and the air supply system.

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.

A dishwasher (100) for pot washing, comprising a detector (160) for automatically detecting what type of washing basket (140) has been placed in the dishwasher (100). This enables automatic selection of water pressure and granule control, such that more sensitive crockery and plates are not damaged. The detector can be an inductive sensor (160) that detects an indicating member (141) of the washing basket. The washing basket can comprise one or several indicating members, for enabling a more reliable detection. A method of operating such a dishwasher (100) comprises the steps of automatically detecting what type of washing basket (140) is placed in the dishwasher, and then controlling the water pressure and granule addition according to what washing basket was detected. A system comprises an above dishwasher and an above washing basket.

A wash-aid dispenser (20) for dispensing dishwasher detergent and rinse-aid employs a DC motor (46) and drive train (43) to separately actuate a door (23) for the release of detergent and a valve (21) for the release of rinse-aid allowing reduced noise and reduce energy operation using a single electric actuator.
