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.

A method for controlling a washing machine includes: detecting a first sensor value by a first set of electrode sensors and a second sensor value by a second set of electrode sensors having at least one electrode sensor which is placed vertically higher than the first set of electrode sensors, the first and second set of electrode sensors comprising at least three electrode sensors which are located at least one of cartridges and configured to detect an amount of detergent contained in the at least one the cartridges; comparing the first sensor value and the second sensor value with a first predetermined value, respectively; passing a predetermined time; redetecting the first sensor value and the second sensor value and calculating a difference sensor value; and determining that the detergent is filling to a height between the first set of electrode sensors and the second set of electrode sensors.

A laundry appliance includes a cabinet defining an opening with a laundry vessel mounted within the cabinet. The laundry vessel defines a treatment chamber. The laundry appliance also includes an electrolytic hypochlorous acid generator upstream of the treatment chamber with respect to a flow of cold water through the laundry appliance and a controller. The controller may be configured for and/or a method of sanitizing the laundry appliance may include opening a valve upstream of the electrolytic hypochlorous acid generator to provide the flow of cold water through the laundry appliance, confirming the presence of the cold water in the laundry appliance after opening the valve, and activating the electrolytic hypochlorous acid generator after confirming the presence of the cold water in the laundry appliance.

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 appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A dispensing assembly selectively dispenses a flow of wash fluid through a discharge nozzle into the wash tub and a camera assembly is used to monitor the wash fluid and diagnose issues related to the detergent dispenser. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain one or more images of the flow of dispensed wash fluid, analyze the one or more images using a machine learning image recognition process to determine an actual detergent content of the flow of wash fluid, determine that the actual detergent content is different than a target detergent content, and implement a responsive action, e.g., such as stopping the operating cycle and notifying a user.

Device for detecting substance groups in a fluid within a household appliance, comprising an emission apparatus that emits a first electromagnetic radiation, characterized by an emission spectrum, into a test volume present with the fluid, further comprising a first measuring apparatus that detects a first spectrum of a second electromagnetic radiation led out of the test volume present with the fluid, further comprising an evaluation apparatus that is provided and designed to evaluate the first spectrum, whereby substance groups can be identified by using reference spectra, with the emission spectrum comprising a wavelength range of visible light and infrared radiation.

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 system for monitoring sanitation agents in a laundry machine comprises a plurality of channels. Each channel has an input port, an output port, and a glass tube. Each input port and output port is adapted to be fluidly coupled to the laundry machine. The system includes a monitoring unit associated with each of the glass tubes. Each monitoring unit includes a bubble detector and a flow rate measurement unit. A beeper is configured to generate an indication of an alarm condition based on a determination made by any one of the monitoring units. The system has a display screen, a memory storing computer-readable instructions, and a controller communicatively coupled to each of the monitoring units. The controller is configured to execute the instructions to wirelessly communicate to a web page a volume of a sanitation agent that has passed through each of the glass tubes.

The present disclosure relates to a method for washing laundry of a laundry load, in particular in a washing drum (B2), carried out by at least one device (100, 200). In one example, the method includes generating steam and applying the steam to the laundry of the laundry load; producing a microemulsion by employing a detergent composition; and washing the laundry of the laundry load using a first wash liquor based on the microemulsion.

A laundry treating appliance comprising a dispensing assembly which can identify laundry treating chemistry filled in a loading cup by way of a material sensor, and supplying said laundry treating chemistry to a proper corresponding bulk reservoir.
