A system for dispensing a detergent solution from a solid detergent into a dishwasher includes a dispenser that can collect water sprayed into the dishwasher and use the collected water to produce the detergent solution by dissolving a portion of the solid detergent, controlling the amount of the detergent solution produced, and releasing the produced detergent solution between cleaning cycles. The dispenser can perform these functions automatically without being electrically powered.

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.

A dishwasher and method utilize an image-based position sensor that is positioned to sense the rotational position of a discretely directable tubular spray element driven by a tubular spray element drive.

A method for cleaning items to be cleaned is disclosed. A cleaning device is used that has at least one cleaning chamber and at least one applicator for applying at least one cleaning fluid to the items to be cleaned in the cleaning chamber. A desired hygiene value is prespecified. The method further includes time-resolved recording of at least two influencing variables which influence hygienization of the items to be cleaned. Hygiene share values are determined from the influencing variables using a prespecified relationship between each influencing variable and the respective hygiene value share of said influencing variable. An expected actual hygiene value at the end of the cleaning from the hygiene value shares is ascertained and compared with the desired hygiene value. At least one of the influencing variables is changed based on the comparison. An inventive cleaning device is also disclosed.

A method for removing stains, in particular tea stains, during a cleaning cycle of a household appliance, such as a dishwashing machine. The cleaning cycle comprises at least a main wash cycle. A cleaning agent is released during the main wash cycle when the temperature inside the household appliance during the main wash cycle exceeds a predetermined temperature threshold, the threshold being higher than about 40° C., for example higher than about 55° C.

A dishwasher includes a dishwashing container accommodating items to be washed. A first hydraulic arrangement is provided to wash the items by a dishwashing fluid and includes a spray device arranged in the dishwashing container, a sump arranged below the dishwashing container, a filter device configured to filter the dishwashing fluid in the dishwashing container and/or the sump, and a circulating pump configured to circulate the dishwashing fluid to the spray device. A second hydraulic arrangement is provided for cleaning the filter device by a cleaning fluid. The second hydraulic arrangement includes the filter device, the sump, a pump arrangement, a storage device for holding the cleaning fluid, a cleaning device for spraying at least one segment of the filter device with the cleaning fluid, and an auxiliary pump arranged between the storage device and the cleaning device for applying pressure to the cleaning fluid.

A dishwashing appliance includes a tub defining a wash chamber for receipt of articles for washing, the tub including a plurality of sidewalls; a door movable between a closed position and an open position, the door comprising an inner panel enclosing the wash chamber when the door is in the closed position; and a dispenser assembly mounted to the inner panel. The dispenser assembly includes a door box including a pump chamber, the pump chamber defining an inlet hole and an outlet hole; a tunnel piece extending from the pump chamber; a bottle removably coupled to the tunnel piece; and a cap connected to the bottle, wherein the cap is configured to receive at least a portion of the tunnel piece therethrough.

The invention relates to a method of automatic dishwashing, comprising: placing soiled wares inside a cleaning volume; providing a first cleaning composition comprising a bleach and a second cleaning composition different from the first composition; and delivering the first composition and the second composition separately to the cleaning volume to contact the soiled wares, wherein: the first composition is delivered to the cleaning volume as a mist and the second composition is delivered to the cleaning volume as a jet; and the first and second compositions are delivered to the cleaning volume at a temperature below 100° C. The invention also relates to a dishwasher and a kit for use in the inventive method.

A laundry treating appliance having a treating chamber and a bulk dispenser and a user interface configured to provide an indication to the user related to the bulk chemistry dispenser and a controller coupled with the user interface and the bulk treating chemistry dispenser and configured to execute an operating cycle including controlling the treating chemistry meter to dispense the predetermined amount of treating chemistry and determine a number of doses of treating chemistry available in the bulk treating chemistry dispenser and method of determining the number of doses and the types of a treating chemistry available in the bulk dispensing system, and providing an indication of the determination on a user interface.
