A dishwashing appliance or variable spray assembly, as provided herein, may include a manifold body, a diverter valve, and a driver. The manifold body may define a fluid inlet, a first flow path, a second flow path, a first spray outlet, and a second spray outlet. The first and second flow paths may be downstream from the fluid inlet. The second flow path may be in fluid parallel to the first flow path. The second spray outlet may be spaced apart from the first spray outlet. The diverter valve may be mounted within manifold body and movable between a first zone position directing wash fluid to the first flow path and a second zone position directing wash fluid to the second flow path. The driver may be disposed outside of the manifold body to motivate the diverter valve between the first zone position and the second zone position.

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.

A dishwasher having a treating chamber with one or more sprayers through which liquid is recirculated into the treating chamber, whereby the impact of the spray emitted from the sprayers impacts the structure forming the treating chamber to generate noise. Damping material is applied to structure forming the treating chamber to reduce the sound level of the impact exterior of the dishwasher.

A dishwasher includes a dishwashing tub in which dishes are washed; a first tank configured to store therein cold washing water to be used for a next stroke; and a second tank configured to store therein hot washing water, which has been used in the dishwashing tub. The second tank is placed adjacently to the first tank to transfer heat from the stored hot washing water to the cold washing water. An opening is configured to deliver the hot washing water to the dishwashing tub; and a circulation pipe is configured to connect the dishwashing tub and the second tank to enable the hot washing water to circulate between the second tank and the dishwashing tub. A circulation valve is configured to allow the hot washing water to pass therethrough or to block the hot washing water from passing therethrough.

A method of treating at least one of laundry or dishes in a treating chamber of an appliance comprising, recirculating liquid through the treating chamber, centrifugally removing particles greater than a predetermined size from the liquid during recirculation of the liquid, and coagulating particles greater than the predetermined size in the liquid during recirculation of the liquid.

A dishwasher includes a main body, a tub provided in the inside of the main body, a basket provided in the inside of the tub to store dishes, an injection unit configured to spray wash water to wash dishes in the basket, and a circulation pump configured to circulate wash water, a sump arranged on a lower surface of the tub, and a connector provided to connect the circulation pump to the injection unit and having a tubular shape. The sump includes a coupling portion extending upward from the lower surface of the tub, and the connector and the injection unit are connected to each other in the inside of the tub by being coupled to the coupling portion.

A dishwasher and a control method thereof are disclosed. The dishwasher includes a tub accommodating an object to be washed, a spray arm rotatably provided inside the tub to spray wash water toward the object to be washed, a sump for storing wash water and collecting wash water sprayed into the tub therein, a filter separably mounted to the sump to remove foreign substances from wash water, a wash pump for supplying wash water stored in the sump to the spray arm, and a circulation passage for diverting at least a portion of the wash water supplied to the spray arm by the wash pump to the sump. After the dishes are washed, all of the wash water introduced into the wash pump is diverted into the filter. Foreign substances present in the wash water are collected in the filter and are discharged outside along with the wash water.

A dishwashing appliance may include a cabinet, a tub, a fluid pump, and a wireless power transmitter. The tub may define a wash chamber within the cabinet. The fluid pump may be in fluid communication with the tub for motivating a flow of wash fluid from the tub when activated. The fluid pump may include a fluid impeller rotatably positioned in fluid communication with the wash chamber, and an electric motor in mechanical communication with the fluid impeller to motivate rotation thereof. The wireless power receiver may be in electrical communication with the electric motor. The wireless power transmitter may be spaced apart from the wireless power receiver in operable communication with the wireless power receiver to transmit an electromagnetic field thereto.

A dishwasher and method for treating dishes according to a cycle of operation, wherein the dishwasher can include a tub at least partially defining a treating chamber, a dish rack movably received within the treating chamber and a spray system fluidly connected to the water supply. The dish rack is configured for receiving dishes or utensils for treatment during the cycle of operation. The spray system can include a set of sprayers located within the treating chamber that are configured to selectively emit spray from the water supply onto dishes or utensils on the dish rack.

A dishwashing appliance includes a tub defining a wash chamber for receipt of articles for washing. A sump is a sump positioned at a bottom of the wash chamber for receiving fluid from the wash chamber. A circulation pump is connected to the sump. The dishwashing appliance also includes a mounting cable extending from the circulation pump. The circulation pump is suspended by the mounting cable.
