A wash monitoring system including a water flow meter that transmits water flow readings of flow through a water line, chemical conduits with color sensors on the chemical conduits and configured to transmit color readings of a chemical within the chemical conduits, and chemical flow meters on the chemical conduits that transmit chemical flow readings of flow through the chemical conduits. The system includes a memory containing processor-executable instructions that cause processors to compare the water flow readings with a range of water flow readings, compare the chemical flow readings with a range of chemical flow readings, compare the color readings with a range of color readings associated with each of the one or more chemical conduits, and initiate an alarm if one of the water flow readings, the chemical flow readings, or the color readings are not within the respective ranges of readings.

A retrofit auxiliary device for distributing cleaning resources to a household cleaning appliance having a treating chamber is described wherein the device can connect to various household cleaning appliances of different makes and models and can learn the flow of water and detergent during various stages of operation and then perform the dispensing itself.

A method of operating a dishwasher appliance, as provided herein, may include detecting a door of the dishwasher appliance in an open position and determining the door is maintained in the open position for a preset minimum continuous period. The method may further include detecting the door in a closed position following the preset minimum continuous period. The method may still further include measuring an additive volume of a wash additive in an additive compartment on the door while the door is in the closed position following the preset minimum continuous period.

A dispenser of washing agents for washing machines has a first tank, to contain a first washing agent, and a first dispensing arrangement, to dispense first dosed amounts of the first washing agent. The first dispensing arrangement comprises a peristaltic pump, which is configured to be driven in a first direction of rotation to cause delivery of the first dosed amounts of the first washing agent. The dispenser comprises a second tank, to contain a second washing agent, and a second dispensing arrangement, to dispense second dosed amounts of the second washing agent. The peristaltic pump has a command arrangement of the second dispensing arrangement, and is configured to be driven in a second direction of rotation, to drive the command arrangement so as to cause dispensing of the second dosed amounts of the second washing agent.

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 detergent dispensing apparatus 3 used for a dish washer and a dish washer comprising the detergent dispensing apparatus 3. The detergent dispensing apparatus 3 comprises a liquid storage box, a liquid outlet pump 32 and a pipeline module. The liquid storage box comprises a first half housing and a second half housing, and the first half housing and the second half housing fixedly connect each other in a first direction so as to define a liquid storage cavity used for storing detergent. The liquid outlet pump 32 is configured to suction the detergent from the liquid storage cavity and dispense the detergent to the exterior of the detergent dispensing apparatus 3. The pipeline module comprises a liquid adding channel used for adding the detergent to the liquid storage cavity, a liquid inlet channel used by the liquid outlet pump 32 for extracting the detergent from the liquid storage cavity, and a liquid outlet channel used by the liquid outlet pump 32 for dispensing the detergent. The second half housing defines at least a portion of a pump accommodating space that is used for accommodating the liquid outlet pump.

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.

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.

The present inventive concept relates to a method for optimizing water usage in a device utilizing water for a group of cleaning procedures, wherein the device comprises a sensor arrangement (518) and a data processing device, wherein the method comprises the steps of: determining a first substance content (400a) of first cleaning phase water from a first cleaning phase of the cleaning procedure (428) using the sensor arrangement (518); in the data processing device, receiving data comprising a target substance content interval requirement (844) of at least one of a plurality of cleaning phases (314); in the data processing device, comparing the first substance content to the target substance content interval requirement (844); and forming cleaning phase water to be used in the at least one of the plurality of cleaning phases (314) by transferring the first cleaning phase water to the at least one of the plurality of cleaning phases (314) based on the comparison.
