A detergent dispenser may be positioned to dispense detergent into a wash tub of a household appliance. The detergent dispenser may include a detergent cartridge. The detergent cartridge may include a detergent strip having a plurality of detergents. One or more ejection mechanisms may be used to expel the detergent from the detergent strip through an outlet of the detergent cartridge.

A dosing system for installation in a domestic dishwasher is disclosed. The dosing system in some embodiments permits the automated delivery of a defined dose of a detergent in powder form into a dishwashing chamber of the dishwasher. It comprises for this purpose a supply chamber for receiving a supply of the detergent and an extracting mechanism for extracting a dose of the detergent from the supply and for delivering the extracted dose into a fall channel. In order to assist with expelling an extracted dose of the detergent powder from the fall channel or/and to accelerate drying of the fall channel, the dosing system in some embodiments includes a fan for generating a blowing air stream which flows through at least parts of the fall channel.

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.

Systems, methods, and software program products for dispensing chemical products to a washing machine. A dispenser receives a conductivity signal from a conductivity circuit having input terminals coupled to a probe in a tank of the washing machine. The dispenser may compare the conductivity signal to a threshold indicative of a low level of conductivity between input terminals of the conductivity circuit. In response to the conductivity signal breaching the threshold, the dispenser may determine the tank of the washing machine is being drained of a washing solution. In response to the conductivity signal subsequently breaching another threshold indicative of a high level of conductivity between the input terminals, the dispenser may determine the tank is being filled, and dispense a predetermined amount of the chemical product into the tank.

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.

A dishwasher, in which a reservoir provided with an electrolyzer is connected to a water collector via a flow path change valve, and wash water in the reservoir is electrolyzed by the electrolyzer during non-operation of the wash water, to generate sterilizing water and to circulate the sterilizing water into the dishwasher, thereby achieving an enhancement in sterilizability of the dishwasher. A method for controlling a dishwasher makes it possible to suppress propagation of microorganisms left in the dishwasher and to remove organic substances, using a sterilizing agent or high-temperature water. It is also possible to reduce generation of offensive odor caused by decomposition of bacteria, through a reduction in the amount of bacteria in the dishwasher. Since sterilization of the dishwasher is automatically carried out, enhanced user convenience is provided.

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 dispensing device for a dishwashing machine, including: a body mounted to a door of the dishwashing machine; a receptacle formed in the body to receive a quantity of a washing or rinsing agent; a lid associated with the receptacle and displaceable in a manner constrained to the body against the action of a spring from an open position into a closed position, wherein the lid comprises an outer face which faces away from the receptacle when the lid is in closed position; a latching apparatus having a striker member assuming a deactivated configuration, in which the striker member is configured to be engaged by the latching member when the lid is closed, and an activated configuration, in which the striker member releases the latching element allowing the lid to pass into the open position; and an opening member which disengages the latching member from the striker element in deactivated configuration, allowing the lid to open.

The present disclosure relates to a dishmachine that includes at least two tanks and methods of using the tanks to isolate, substantially isolate, or incrementally isolate different chemistries from each other during a cycle. The disclosed dishmachine design and method allows for the use of two different, and potentially incompatible, reactive, or offsetting chemistries to be used in the same dishmachine cycle.
