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.

Systems and methods are described, which relate to the control of additive dispensers to provide defined amounts of one or more additive compounds to water to produce customized water. A given additive dispenser may include multiple inputs and/or outputs. Predefined water profiles may be stored in memory. A given water profile may define the amounts of additives to be delivered by the additive dispensers to achieve desired water characteristics. A controller may determine actual water characteristics of input water based on corresponding sensor data, and may compare the actual water characteristics to desired water characteristics in order to determine the amount of additive or additives that should be delivered to the input water to achieve the desired water characteristics. The additive dispensers may be network-enabled and may include transceivers configured to receive instructions related to production of customized water from a user device.

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 system for dosing substances such as cleaning and/or care agents is disclosed. The system includes a dosing device, at least one energy source, a control unit, a sensor unit, and at least two cartridges for respectively accommodating at least one of the cleaning and/or care agents. The at least two cartridges are capable of being coupled to the dosing device.

A household dishwasher includes a washing chamber, a control apparatus for running a washing program from a number of washing programs, a metering system having a supply unit for receiving an individual dose of a first cleaning agent and supplying the individual dose into the washing chamber at a metering point in time while running the washing program, and an automatic metering apparatus for automatically metering a plurality of metering quantities from a supply of a second cleaning agent in the form of a solid material into the washing chamber at the metering point in time, and a sensor apparatus configured to detect a state of the metering system and to emit a sensor signal depending on the detected state of the metering system. The control apparatus runs the washing program depending on the sensor signal.

A conveyor dishwashing machine (1) has at least one washing zone (7), and at least one final rinse zone (8) which is connected downstream (as viewed in the transport direction (T) of the wash items) of the at least one washing zone (7). The conveyor dishwashing machine (1) has a transport apparatus for transporting the wash items through the treatment zones (6, 7) of the conveyor dishwashing machine (1) so that the wash items are situated at least in regions in a washing plane (5) which runs horizontally. The washing plane (5) is configured as a main washing plane, and there is at least one additional washing plane (6) in at least one of the treatment zones (7, 8) of the conveyor dishwashing machine (1), in which additional washing plane (6) wash items can be treated.

A detergent dispenser may be positioned to dispense detergent into a wash tub of a household appliance. The detergent dispenser may include a detergent cartridge. The detergent cartridge may include a detergent strip having a plurality of detergents. One or more ejection mechanisms may be used to expel the detergent from the detergent strip through an outlet of the detergent cartridge.

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.

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 system for monitoring the operation of a commercial dishwasher (2), which is embodied as a box-type dishwasher or as a conveyor dishwasher, includes at least one temperature sensor (60) designed to record a temperature profile with respect to time which corresponds to the temperature profile with respect to time to which an item of washware is subjected when it is treated in the dishwasher (2). The system further includes an evaluation device (62) designed to receive and to evaluate the temperature profile recorded by the at least one temperature sensor (60), wherein the evaluation device (62) is further designed to ascertain a value of a notional unit of quantity of heat from the temperature profile recorded by the temperature sensor (60). A dishwasher (2) including a corresponding monitoring system and a method for monitoring the operation of a dishwasher (2) are also provided.
