A dishwasher includes a case, injection arms, a sump including an injection flow path coupling portion, a washing pump for supplying washing water stored in the sump to the injection arms, and a switching valve including a flow path distributor for distributing washing water to injection arms. The flow path distributor defines distribution holes. When the flow path distributor is in a reference position, the distribution holes are positioned so that all of the injection arm supply holes are opened, and, when the flow path distributor is rotated by a first angle from a reference position, the distribution holes are positioned so that any one of the injection arm supply holes is opened. The injection flow path coupling portion includes a plurality of support ribs protruded toward the flow path distributor and including a support rib corresponding to at least one of the distribution holes.

A dishwasher has a treating chamber for receiving dishes for treatment according to an automatic cycle of operation and a dispensing system for storing and dispensing a treating chemistry to the treating chamber during the cycle of operation. The dishwasher may dispense a treating chemistry when a temperature of a liquid in the treating chamber satisfies a predetermined temperature threshold. The temperature of the liquid may be maintained to satisfy the predetermined temperature threshold for a predetermined period of time based on the treating chemistry.

A vessel contains a quantity of liquid and has a duct connected to an outlet of the vessel. A dispensing device can be actuated in order to cause the quantity of liquid to flow out of the vessel through the duct. A color sensor is also included, which faces towards a monitoring region situated in one of the vessel, the duct and the dispensing device. The color sensor is configured for providing a color signal indicative of the color of the quantity of liquid arriving at the monitoring region. A control device is configured for receiving the color signal from the color sensor and for actuating the dispensing device as a function of the color signal. A method is for dispensing the quantity of liquid from the vessel.

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 hydraulic control device for liquid-conducting household appliances or systems comprises:a hydraulic unit (11), having a hydraulic body (15) defining a duct (30) for the liquid, the duct (30) having an inlet (18i) and an outlet (31), the duct (30) being at least partially defined with an electrically insulating material,an electrical valve arrangement (EV, SH) on the hydraulic body (15), which is electrically switchable between a closing position and an opening position, to prevent or enable, respectively, passage of the liquid between the inlet (180 and the outlet (31) of the duct (30),a flow sensor on the hydraulic body (15). The flow sensor is a non-mechanical flow sensor comprising at least two electrical detection elements (42), prearranged for contact with the liquid that flows in the duct (30) and carried by at least one support (41), that preferably at least partly extends within, or faces the inside of, the duct (30) and/or has two opposite major faces that are substantially parallel to a direction of a flow of the liquid.

A method of controlling a dishwasher is disclosed. The method includes supplying water to a sump, driving a wash pump using a wash motor, introducing a detergent into a tub, and determining whether the amount of bubbles is excessive based on the value of current applied to the wash motor. The determining whether the amount of bubbles is excessive is performed after a lapse of a predetermined period of time since the start of the introducing the detergent into the tub.

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.

A dishwasher has a housing (10) with a wash chamber (20) and a top wall (204) with a non-planar surface (214;214) facing downwardly into the wash chamber, the surface having portions (216,218; 226,228) facing downwardly and facing in different horizontal directions (H1,H2; HX,HY,HP,HQ). Nozzles (402) mounted within the wash chamber spray a liquid upwardly within the wash chamber. The surface portions redistribute the upwardly-sprayed water in horizontal directions to provide a more uniform washing action. A portable dishwasher may have a fresh water reservoir (422) and a used water reservoir (430) mounted in the housing beneath the wash chamber. The used water reservoir may be removably mounted in the housing so that the user can remove used wash water by removing the used water reservoir. The portable dishwasher can be used at a location remote from a sink.

An auxiliary gray water supply device captures used wash water from a commercial warewashing machine for supply to a pre-rinse station without substantial modification of the commercial warewashing machine. The captured wash water and treatment agent are delivered to a pre-rinse station for pre-rinsing of dishes that will be washed within the commercial warewashing machine.

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.
