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 fluid-driven chemical product dispensing system dispenses fluid chemical product concentrates. The dispensing system includes a fluid drive unit powered by flow of a fluid, such as a diluent, and a pump which delivers the fluid chemical product concentrate from a supply to a destination. Upon exit from the fluid drive unit, the diluent is also delivered to the destination, where it mixes with the dispensed fluid chemical product concentrate to form a use solution. The dilution ratio of the volume of fluid chemical product concentrate dispensed per unit time versus the volume of diluent exiting the drive unit per unit time is constant over a defined range of diluent flow rates.

A cleaning device (110) for cleaning articles (112) to be cleaned is proposed. The cleaning device (110) includes at least one cleaning chamber (118) for receiving the articles (112) to be cleaned. In addition, the cleaning device (110) includes at least one application device (124) for acting upon the articles (112) to be cleaned with at least one cleaning fluid. The cleaning device (110) additionally comprises at least one cooling surface (158) which points to the cleaning chamber (118) and at least one cooling container (160) which is thermally coupled with the cooling surface (158) for receiving a cooling liquid. The cleaning device (110) comprises at least one control system (178) which is set up to control at least one regeneration step in the cleaning device (110). The regeneration step includes the following substeps: d) fill the cooling container (160) with cooling liquid; e) heat the cooling liquid in the cooling container (160); and f) remove the cooling liquid from the cooling container (160).

A household appliance includes a selectively mountable wireless communication module. The selectively mountable wireless communication module can be selectively mounted in a toe kick area of the household appliance. The household appliance can be, but is not limited to, a dishwasher, an oven, a refrigerator, a freezer, a microwave, a washing machine, a dryer, or a combo washer-dryer.

Provided are a method performed by an appliance for washing and rinsing goods, where some of the goods loaded into the appliance are sensitive to process water temperature changes, and an appliance performing the method. The method may include receiving via a user interface, an instruction that an appliance, during execution of a general-type washing program, should take into account that goods sensitive to temperature changes are loaded into the appliance, measuring a temperature value in a washing compartment of the appliance upon executing a draining process, and supplying fresh water to the washing compartment of the appliance. The method may include measuring, when the fresh water has been supplied, whether the process water being accommodated in a sump of the appliance is at a target temperature value or not and if not adjusting the temperature of the process water in the sump to attain the target temperature value.

Methods of operating a dishwashing appliance are provided herein. A method may include measuring a temperature at a temperature sensor and identifying a runaway heat condition within a wash chamber based on the measured temperature. The method may also include directing a volume of water to the wash chamber in response to identifying the runaway heat condition and circulating the volume of water within the wash chamber for a recirculation period.

A dishwasher utilizing one or more sprayer rings disposed proximate to one or more tines of a dishwasher rack, where the sprayer ring(s) are in fluid communication with a fluid supply that is configured to supply a fluid to the one or more sprayer rings to spray fluid onto utensils disposed within the wash tub.

A dish washer includes: a washing tank including a sump at a bottom surface thereof; a water storage unit disposed inside or outside the washing tank to store washing water to be supplied to the washing tank; a heat pump system including a compressor that compresses and circulates refrigerant, a first heat exchanger disposed in the sump, an expansion apparatus, and a second heat exchanger disposed in the water storage unit to heat washing water for washing the dishes; and a reverse valve that changes a flow of refrigerant flowing through each of the first heat exchanger and the second heat exchanger to allow each of the first heat exchanger and the second heat exchanger to be switched from each other between a heating mode for heating the washing water and a heat recovery mode for recovering heat from washing water discharged to the outside from the washing tank.

A method for controlling a dish washer includes: supplying washing water to a water storage unit; delivering washing water from the water storage unit to the washing tank; heating washing water in the sump by a first heat exchanger disposed in the sump; injecting heated washing water through an injection arm; recovering heat from heated washing water by the first heat exchanger and transferring heat to a second heat exchanger disposed in the water storage unit after completion of washing; and discharging washing water cooled by the first heat exchanger from the sump to an outside. The dish washer includes a heat pump system including the first heat exchanger, the second heat exchanger, an expansion apparatus, that expands refrigerant received from the first heat exchanger or the second heat exchanger, a compressor that compresses and circulates refrigerant received from the first heat exchanger or the second heat exchanger.

The present disclosure relates to a dishwasher having a heat pump, including a dishwasher body provided with a tub configured with a washing space therein and a sump provided at a bottom of the tub to temporarily accommodate washing water; a washing water storage unit provided in the dishwasher body to store washing water therein; a heat pump having a compressor, an evaporator, an expansion apparatus, and a condenser provided to exchange heat with the washing water of the washing water storage unit; and a controller that controls the heat pump to increase the temperature of the washing water of the washing water storage unit. As a result, a heating time of washing water may be shortened, thereby suppressing a time required for washing dishes from being prolonged.
