A method for setting a time of a release of a cleaning agent during a cleaning cycle in a household appliance includes obtaining an evolution over time of a local parameter inside the appliance, the local parameter comprising an acceleration induced by the cycle or a temperature inside the appliance; obtaining reference patterns of evolutions of the local parameter during a cycle comprising different cleaning steps including a step adapted for releasing the cleaning agent at a predetermined adapted time; comparing the evolution of the local parameter to the reference patterns and identifying a cleaning step within the cycle when a similarity between a reference pattern and the evolution is above a predetermined threshold, and setting the release of the agent at the predetermined adapted time within the identified cleaning step when the identified step corresponds to a step adapted for releasing the agent.

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 washing machine and an operating method thereof are disclosed. A washing machine according to an embodiment of the present invention comprises: a washing tub; a touch screen for outputting a graphical object corresponding to a washing-related function which can be performed by the washing tub; a detergent supplying unit which is formed to receive a laundry detergent in an inner space thereof and supply the received laundry detergent to the washing tub through a supply fluid path; and a control unit which detects a load and a contamination level of laundry in response to input of a washing start command and determines an input quantity of the laundry detergent received in the detergent supplying unit on the basis of the detected load and contamination level. In addition, the control unit displays a graphical object related to the determined laundry detergent input quantity on the touch screen.

A laundry washing machine comprising: a cabinet, a washing tub housed inside the cabinet, a drum rotatably housed inside the tub, and an electric liquid supplying device mounted in or on the drum and configured for dispensing a liquid in an inner region of the drum. The invention is also related to a method for operating such a laundry washing machine.

In order to increase an adsorption rate of softener for laundry, a method of controlling a washing machine according to an embodiment includes performing a first rinsing process based on a first target water level and a first duty ratio of a motor; when a second rinsing process is started, supplying water to an intermediate water level of a fixed tub; additionally supplying water to a second target water level together with the softener; setting a duty ratio of the motor to a second duty ratio higher than the first duty ratio; and driving the motor based on the second duty ratio.

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.

A device for dosing a detergent ingredient into the drum of an automatic washing machine which can include a reservoir, a one-way valve, an inlet, and a dosing manifold.

The present disclosure relates to a washing machine and a control method of the same. The washing machine includes: a detergent supply device which supplies a liquid additive to the tub; and a controller which controls the operation of the detergent supply device. The detergent supply device includes: a plurality of cartridges which contain the additive respectively; an electrode sensor which detects conductivity of the additive contained in the plurality of cartridges; and a pump which extracts the additive contained in the cartridge. The controller determines a type of additive contained in the cartridge based on a detection value of the electrode sensor.
