A detergent container for a cleaning device (100) having a receiving slot and a contacting apparatus (106) for the detergent container (200). The detergent container has a housing for storing a detergent, wherein the housing is formed to be inserted into a receiving slot of the cleaning device (100). The detergent container has an electrically conductive contact region which is arranged on an outer side of the housing and includes a content encoding that represents a detergent container content. In the inserted state of the housing, the contact region can be contacted using the contacting apparatus (106) in order to detect the content encoding.

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 laundry treating appliance includes a treating chamber provided for receiving laundry for treatment, a controller having a memory in which is stored a set of executable instructions including a set of cycles of operations. The laundry treating appliance also includes a user interface operably coupled with the controller and having a touchscreen configured to provide an input and output function for the controller.

A washing machine of the present disclosure includes: a tub in which water is stored; a drum which is rotatably provided in the tub, and accommodates laundry; and a detergent supply device which supplies a liquid additive to the tub, wherein the detergent supply device includes: a cartridge which contains the additive; a pump which extracts the additive contained in the cartridge; an outlet flow path pipe which is connected to the cartridge, and through which the extracted additive flows toward the tub; and a flow path pipe sensor which is installed in the outlet flow path pipe, and detects an existence of the additive in the outlet flow path pipe.

A household cleaning appliance having a rotatable drum located within the interior and defining a treating chamber for receiving an article for treating and a method for operating the household cleaning appliance. The household cleaning appliance includes a dispensing system that includes and can be operated as a non-bulk dispensing system or as a bulk dispensing system in a household cleaning appliance.

A washing machine includes: a tub and a detergent supply device which supplies a liquid additive to the tub, wherein the detergent supply device includes: a cartridge containing the additive; a check valve assembly including a check valve for controlling extracting of the additive, and a check valve housing forming a space in which the extracted additive is temporarily stored; a pump for extracting the additive by changing a pressure in the space; and an outlet passage through which the temporarily stored additive is discharged, wherein the check valve assembly comprises a first outlet opening communicating with the cartridge, a second outlet opening communicating with the outlet passage, a first check valve for opening and closing the first outlet opening, and a second check valve for opening and closing the second outlet opening, wherein the first and second check valves are opened in the same direction.

A method and system for setting parameters of a treatment cycle in a household appliance is provided. First a model establishing a relationship between sets of configuration parameter values of achievable treatment performance is obtained. Then a target treatment performance for the treatment cycle is obtained. Values for a subset of a configuration parameter are fixed, the subset comprising at most all configuration parameters but a remaining configuration parameter. Then, a value for the remaining configuration parameter is determined. For this value, a difference between the target treatment performance and an achievable treatment performance predicted by the model using said value is below a predetermined threshold. Finally, the parameters of the treatment cycle, which can be setting parameters of the treatment cycle in the household appliance are output. The parameters comprise the determined value and the fixed values.

A method is provided for monitoring a supply of a cleaning agent. The method includes performing a check of whether the supply of the cleaning agent is likely to be used up. The check is based, at least in part, on quantity information which is representative of an amount of the cleaning agent in a user's supply and on consumption information which is indicative of the user's expected consumption behavior with respect to the cleaning agent. Further, a device is provided for performing the method for monitoring the supply of the cleaning agent.

The disclosure relates to a method including capturing and/or obtaining a reservoir information item at a dispensing module for a detergent and/or cleaning agent, with the reservoir information item representative of at least one property of a reservoir for the detergent and/or cleaning agent, an application specification for the detergent and/or cleaning agent contained in the reservoir, and/or a property of the detergent and/or cleaning agent contained in the reservoir, and the reservoir is connected or connectable to the dispensing module. The method further includes determining and/or causing the determination of a dispensing control information item depending at least in part on the reservoir information item, with the dispensing control information item configured to at least partly control the dispensing of the detergent and/or cleaning agent by the dispensing module.

A laundry treatment composition supply system to supply laundry treatment composition to multiple washing machines. The system can include a first supply container and a second supply container. Each of the supply containers can be operably engaged with a level sensor. Upon a low liquid level signal from a sensor associated with a container, a controller system can switch supply of the laundry treatment composition from the container having a low level to another container. The laundry treatment composition can be pumped from one supply container or the other supply container.
