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.

A method of operating a washing machine appliance includes filling a wash tub with a wash liquid during a first cycle. The method also includes receiving a pause input after filling the wash tub and before draining the wash tub during the first cycle. In response to the pause input, the first cycle is paused for a pause duration. The method further includes incrementing a pause counter in response to the pause input and storing the pause duration after pausing the first cycle. The method also includes filling the wash tub with a wash liquid during a second cycle after the first cycle and automatically pausing the second cycle after filling the wash tub with the wash liquid during the second cycle, based on the pause counter and the stored pause duration

A laundry treatment appliance having a laundry treatment chamber adapted to receive laundry to be treated, a treatment agent delivery system configured to store an amount of treatment agent sufficient for performing a plurality of treatment cycles, and to deliver a treatment agent dose towards the laundry treatment chamber, the treatment agent dose being a fraction of the stored amount of treatment agent, a water supply unit configured to supply fresh water having a first level of hardness to the laundry treatment appliance, and a water softening system configured to selectively receive the fresh water from the water supply unit and to selectively provide softened water having a second level of hardness lower than the first level of hardness to said treatment agent delivery system.

A laundry treatment appliance comprising: a fresh water supply; a treatment chamber; a water softener; a liquid delivery system connected to the water supply, the water softener, and a treatment agent delivery system configured to store a water-soluble treating agent pod and/or a steam generator. The liquid delivery system is configured to supply fresh water from the water supply or soft water from the water softener into the treatment chamber. The appliance can perform one or more treatment cycles including at least one of: a first cycle in which the process liquid supplied by said process liquid delivery system further includes laundry treatment agents contained in the pod, and a second cycle in which the steam generator is activated to steam into the treatment chamber. The appliance further comprises a control unit to activate the water softener to provide the process liquid delivery system with soft water.

A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be diverted into the modular infrastructure prior to draining into the primary infrastructure. Once diverted, the precedent use water is received at a reservoir system where it is treated for a subsequent use. Treatment may include filtration and/or chemical treatment, and may be based upon sensor feedback from the reservoir system. Once treated, the water is ready for subsequent use and may flow from the reservoir system, via the modular infrastructure, to a subsequent point of use, such as a toilet.

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 water reuse control method of a multiple-drum washing machine, having a first washing drum and a second washing drum. When the first drum reaches a drainage process, comparing a time for the second drum to reach a water supply process T.sub.12 to a time for the first drum to reach a next drainage process T.sub.11; if T.sub.12<T.sub.11, the first drum waits until water is supplied into the second drum; if T.sub.12≧T.sub.11, water in the first drum is directly drained. Alternatively, when the first drum reaches the water supply process, comparing time for the second drum to reach the drainage process T.sub.22 to time for the first drum to reach a next water supply process T.sub.21; if T.sub.22≧T.sub.21, clean water is directly supplied into the first drum; if T.sub.22<T.sub.21, the first drum waits until the second drum drains water.

A washing machine has a reservoir configured to hold materials to be washed, the reservoir positioned to receive water from a water source, a drain pipe connected to the reservoir, at least two cleaning agent dispensers, a controller connected to the cleaning agent dispensers, the controller arranged to control water flow into and out of the reservoir, and dispensing of agents from the cleaning agent dispenser, and at least one sensor arranged to sense contents of one of either the water or materials to be washed and communicate the contents to the controller, the controller to dispense cleaning agents based upon the contents. A method of dispensing cleaning agents includes receiving signals from at least one sensor, wherein the signals provide information about soil in a reservoir, using the information to select appropriate cleaning agents from a set of cleaning agents, and dispensing selected cleaning agents into the reservoir.

In a control method of a washing machine, a primary nephelometric turbidity unit (NTU) of washing water is sensed before a washing course is started in a washing cycle, a second NTU is sensed based on the primary NTU, and a washing time, an amount of washing agent, and/or a number of times of rinsing are varied based on a difference value between the primary NTU and the secondary NTU, thereby improving washing performance and washing efficiency.

The subject disclosure relates to a clothing washing system, an apparatus for generating nano microbubble ionic water, and a method of washing clothes.
