The present invention relates to a method of handling process water in a household appliance (1) and to a household appliance, for example a dish washer. The household appliance comprises a wash tub (3) for performing wash program cycles and a tank (5) for storing process water to be re-used in a following program cycle, the method comprising the steps of: determining (101) the type of detergent used in the household appliance with a sensor unit (7), measuring (102) the amount of detergent in the process water with the sensor unit, comparing (105) at least one sensor unit output value with a predetermined threshold value to define the quality of the process water, and storing (106) at least a part of the process water from a rinse cycle in the tank (5) when the sensor unit output value complies with the predetermined threshold value related to the quality of the process water.

An adaptive dosing system having a control module, a flow sensor unidirectionally connected to the control module for reporting a volume of a fluid passed through the system, a pump for dosing a required volume of the fluid and being uni-directionally connected to and controlled by the control module and a communication module bi-directionally connected with the control module, the communication module being configured to connect via Internet with an application server and a database server.

The present invention relates to a method of controlling a dispenser for dosing a product in a washing machine leading to an optimized dosing result, a dispenser controller programmed with an algorithm to execute the method of the present invention as well as the use of said dispenser for controlling dosing of a product in a washing machine.

A laundry treating appliance having a trating chamber and a bul 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 portable handheld submersible ultrasonic cleaning device has a generally elongate body defining proximal and distal ends, a power supply and an ultrasonic transducer powered thereby, wherein the distal end exposes the ultrasonic transducer to agitate surrounding water when the base is submerged in the water use. A propeller device comprising a propeller may force the water across the ultrasonic transducer. When cleaning, the device may be held with the distal end thereof submerged for enhanced cleaning and removing surface contaminants such as dust, dirt, oil, pigments, bacteria and the like. The device may be stood upright upon the base on the floor of a container for hands-free application of ultrasound whilst cleaning.

A condition warning system for an apparatus such as a pot and pan washing machine, a control system and control methods for a pot and pan washing machine are provided. The condition warning system includes a control system that monitors operational, safety or compliance parameters of an apparatus, and a light that illuminates a location below (or above) an operator's direct line of sight, and which is outside of the operator's direct line of sight. The control system and control methods include a punitive wash action lockout, an extended wash cycle time, and a deep clean wash cycle.

An out-of-product alarm process includes initiating an out-of-product check by sending a signal to a controller from an optical sensor assembly connected to a fluid delivery medium for delivering a product to a fluid dispensing site, performing an out-of-product check, running an alarm cycle with the controller after receipt of an out-of-product signal, and executing a corrective action. Performing the out-of-product check includes directing light into the fluid delivery medium, generating a detector output based on detected light within the fluid delivery medium, determining an out-of-product state within the fluid delivery medium based on a comparison of the detector output to an out-of-product threshold, starting an out-of-product timer, when the out-of-product state is determined, and determining an out-of-product event when the out-of-product timer reaches a threshold out-of-product time period.
