A method for the dosing of cleaning agents in cleaning machines includes the steps: receiving the control information items; wherein the control information items are dependent on an information item about a cleaning machine; determining the progress of a cleaning operation; dosing of cleaning agent depending on the received control information items and the determined progress of the cleaning operation; wherein the information item about the cleaning machine can be manually input via a user interface.

A conveyor dishwasher includes at least one wash zone and at least one final rinse zone, wherein the at least one wash zone is designed to spray wash liquid, wherein the wash liquid is, at least proportionally, liquid which has already been used for final rinsing in the at least one final rinse zone and to which a wash chemical is added in a metered manner or is fresh water to which a wash chemical is added in a metered manner, wherein the conveyor dishwasher has a metering pump for adding the wash chemical in a metered manner to the liquid to be sprayed in the at least one wash zone, and wherein a controller is associated with the conveyor dishwasher in order to actuate the metering pump and a wash pump or final rinse pump of the dishwasher.

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.

The invention relates to a device for particle sizing of particles distributed in a fluid within a household appliance, comprising at least one first emission means emitting a first electromagnetic radiation along a first optical axis into the fluid present in a test volume, at least one first measuring means detecting at least one characteristic of a second electromagnetic radiation emerging from the fluid an evaluation means provided and adapted to evaluate the characteristics of the second electromagnetic radiation, whereby particle sizes can be detected using reference characteristics, wherein the emitted first electromagnetic radiation is quasi-monochromatic or is a sequence of predetermined wavelengths within a predetermined time interval, the first measuring means being arranged off the first optical axis

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

A dishwasher utilizing one or more sprayer rings disposed proximate to one or more tines of a dishwasher rack, where the sprayer ring(s) are in fluid communication with a fluid supply that is configured to supply a fluid to the one or more sprayer rings to spray fluid onto utensils disposed within the wash tub.

A dish treating appliance for treating dishes according to an automatic cycle of operation and including a tub at least partially defining a treating chamber, multiple sprayers emitting a liquid into the treating chamber, and a diverter valve having a rotatable valve body, which can be rotated to discrete rotational positions to selectively fluidly couple with the multiple sprayers. A rotary drive is located exteriorly of the tub and comprises a housing defining an interior with a liquid leak reservoir, a motor carried by the housing, an output shaft rotationally driven by the motor, extending through the housing and the tub, and operably coupled to the valve body, and a printed circuit board (PCB) located within the housing.

Among other things, a method is disclosed which includes the following: acquiring at least one set of acceleration data indicative of a progression of measured acceleration values; determining status data indicative of a process step within a cleaning program performed by a dishwasher; outputting or causing the output of the determined status data. Further revealed is a device for executing and/or controlling this method, a system with one or more devices for executing and/or controlling this method and a computer program for executing and/or controlling this method by employing a processor.

A dish washer minimizes a possibility of deviation in a detergent supply amount regardless of a change in power supplied to an electric motor by controlling the detergent supply amount based on the number of revolutions of a roller of a detergent pump. The dish washer includes a tub and a detergent supply. The detergent supply includes a container configured to store detergent and a detergent pump configured to supply the detergent in the container to the tub. The detergent pump includes a tube that guides the detergent discharged from the container to the washing space, a roller that pressurizes the tube and revolves about a revolution axis to thereby cause the detergent inside the tube to flow, a pump motor configured to generate driving force to revolve the roller about the revolution axis, and a roller sensor configured to sense a location of the roller.
