A dishwashing appliance, as provided herein, may include a cabinet, a tub, a water tank, a wet air duct, a dry air duct, a water supply conduit, a diverter valve, and a diverted branch. The tub may be housed within the cabinet and may define a wash chamber. The water tank may be mounted within the cabinet outside of the wash chamber. The wet air duct may extend from the wash chamber to the water tank. The dry air duct may extend from the water tank to the wash chamber. The water supply conduit may extend to the wash chamber. The diverter valve may be disposed along the water supply conduit upstream from the wash chamber. The diverted branch may extend from the diverter valve to the water tank to selectively guide water from the water supply conduit to the water tank.

A method for removing moisture from moist air in an appliance, such as a treating chamber of a dishwasher, wherein a drying system includes a condensing system and heat exchange systems that enhance condensation with both ambient air and cold water. The method includes storing cold water for use during a cycle of operation; recirculating the moist air in the treating chamber through a condenser; during the recirculating, flowing ambient air over the condenser; and during the recirculating and after the flowing ambient air, flowing the cold water over the condenser.

A dishwasher for treating dishes according to an automatic cycle of operation includes a tub at least partially defining a treating chamber with an access opening. A door selectively closes the access opening. At least one dish rack is located within the treating chamber. A rotating arm assembly is located within the tub below the at least one dish rack and has a rotatable hub with a liquid conduit. A spray arm is carried by the hub and fluidly coupled to the liquid conduit. An air mixing arm is carried by the hub.

A dishwasher, in particular a domestic dishwasher, including a washing compartment, at least one washing basket disposed in the washing compartment to hold items for washing, and a door configured to close the washing compartment. The door has a planar surface to form an inner face of the door as a whole or a part thereof. When the door is closed, a guide structure including a plurality of individual guide elements projects in a raised manner from the planar surface into an interior of the washing compartment and is disposed so as to guide a drying fluid flowing along the inner face of the door onto the items in the washing compartment, when the dishwasher is in drying mode.

A dishwashing appliance includes a tub defining a wash chamber. An inlet is defined in the tub and provides air flow into the wash chamber. An air handler selectively urges air through the inlet in one of a first direction and a second direction different from the first direction. The air flows from the inlet and through the wash chamber of the tub along a first defined path when the air handler urges air through the inlet in the first direction, and the air flows from the inlet and through the wash chamber of the tub along a second defined path when the air handler urges air through the inlet in the second direction.

A drying system includes a tub defining a wet chamber with an outlet defined in the tub. The drying system also includes a heat exchanger comprising a plurality of heat pipes. Each heat pipe of the plurality of heat pipes has an evaporator section and a condenser section. The evaporator sections of the plurality of heat pipes define an evaporator section of the heat exchanger. The condenser sections of the plurality of heat pipes of the heat exchanger define a condenser section of the heat exchanger. The evaporator section of the heat exchanger is in fluid communication with the outlet to receive a flow of humid air from the outlet. The dishwashing appliance also includes an inlet defined in the tub. The inlet is configured to receive a flow of dry air from the condenser section of the heat exchanger.

A dishwasher includes a tub defining a washing space and accommodating dishes and a heat pump apparatus configured to heat wash water introduced into the tub. The heat pump apparatus includes a compressor configured to compress refrigerant, a first heat exchanger configured to heat water introduced into the tub, a first expansion valve configured to expand refrigerant, a second heat exchanger to which refrigerant is introduced from the first expansion valve, a second expansion valve disposed in parallel with the first expansion valve, a third heat exchanger disposed in parallel with the second heat exchanger, and a four way valve connected with the compressor, the first heat exchanger, the second heat exchanger, and the third heat exchanger and configured to change a flow path of the refrigerant.

The present disclosure relates to a dish washer having a heat pump, and the dish washer may include a washing tank having an accommodation space for storing dishes therein; an injection arm disposed inside the washing tank, and provided with a plurality of nozzles to inject washing water or air to the dishes according to a washing stroke and a drying stroke; a duct unit that defines a passage for delivering air to the injection arm; a suction fan that suctions the air and supplies the air to the injection arm; and an air heating element provided inside the duct unit to heat the air to be supplied to the injection arm, wherein the injection arm is rotatably mounted about a rotary shaft, and the plurality of nozzles rotate the injection arm by a pressure that injects the air.

A water-conducting domestic appliance, in particular a dishwasher, includes a wash container for holding items being washed, a first container and a second container for holding water. A a thermal insulation is arranged between the first container and the wash container. The second container is arranged in thermal contact with the wash container. A decanting device is provided for transferring the water from the first container into the second container to dry the items being washed.

A condensate drain pipe apparatus for providing drainage for a condensate pump includes a main drain having a main top end, a main bottom end, and a main sidewall extending therebetween. A dishwasher drain has a main end coupled to the main sidewall of the main drain, a dishwasher end, and a dishwasher sidewall extending therebetween. The dishwasher drain is in fluid communication with the main drain. The dishwasher drain extends perpendicularly from the main drain and the dishwasher end is configured to be coupled to a dishwasher drainage tube. A condensate drain has a drain end coupled to the dishwasher sidewall of the dishwasher drain, a hose end, and a condensate sidewall extending therebetween. The condensate drain is in fluid communication with the dishwasher drain and the hose end is configured to be coupled to a condensate pump hose.
