An apparatus for removing moisture as liquid from moisture-laden air in an appliance is provided. The apparatus includes a body that defines a channel extending from a first position to a second position and a serpentine flow path between the first position and the second position that operates to redirect the moisture-laden air to remove the liquid from the moisture-laden air. The body includes an opening at the serpentine flow path that is closed when the apparatus is secured to the wall of the appliance. In operation, the body cooperates with the wall to cause the moisture-laden air entering the channel at the first position through an inlet opening in the wall to pass into the serpentine flow path to remove the liquid from the moisture-laden air before the liquid exits the channel at the second position through an outlet opening in the wall.

A dishwasher appliance is provided. The dishwasher appliance includes a cabinet and a tub positioned within the cabinet. The tub may define a wash chamber. The dishwasher appliance may also include a drying system comprising a cooling conduit, a first fan, and a second fan. The cooling conduit may define a cooling conduit passage that is in fluid communication with the wash chamber. The first fan may be operable to draw wash chamber air into the cooling conduit passage. In addition, the second fan may be operable to direct a flow of ambient air onto an exterior surface of the cooling conduit.

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 drying system includes a tub defining a wet chamber, a water storage chamber, an inlet defined in the tub and providing fluid communication into the wet chamber and a heat pipe heat exchanger. The heat pipe heat exchanger includes a condenser section and an evaporator section. The condenser section is in operative communication with the inlet upstream of the wet chamber and the evaporator section is in operative communication with the water storage chamber.

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 dishwashing appliance includes a tub defining a wash chamber. The dishwashing appliance also includes an inlet defined in the tub and providing fluid communication into the wash chamber. A sump is positioned at a bottom of the wash chamber for receiving fluid from the wash chamber and a heater is in operative communication with the sump. The dishwashing appliance also includes a heat pipe heat exchanger having a condenser section and an evaporator section. The condenser section in operative communication with the wash chamber and the evaporator section is in operative communication with the sump.

A dishwashing appliance includes a tub defining a wash chamber, a water storage chamber, an inlet defined in the tub and providing fluid communication into the wash chamber, and a heat pipe heat exchanger. The heat pipe heat exchanger includes a sealed casing, a working fluid contained within the sealed casing, a condenser section, and an evaporator section. The condenser section is in operative communication with the inlet upstream of the wet chamber. The dishwashing appliance also includes a fluid circulation system configured to deliver fluid to the wash chamber from the water storage chamber. The fluid circulation system includes a spray nozzle configured to spray wash fluid onto the evaporator section of the heat pipe heat exchanger.

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. Optionally, the method can also include a charge or charges of warm, ambient air or ambient air with moist air during recirculation of moist air.

A household dishwasher includes a wash container for holding dishes to be washed and a fill reservoir attached to the wash container. The fill reservoir is filled with fresh water from a fresh water network, and a quantity of fresh water required for the wash sub-cycle is removed from the fill reservoir and feed into the wash container. A heat pump includes an evaporator which is thermally coupled to the fill reservoir to extract heat energy from stored fresh water, and a condenser via which heat energy is fed into an interior space of the wash container. Disposed between the interior space of the wash container and an interior space of the fill reservoir is a single-layer or multilayer insulation material system to reduce a heat flow from the wash container.

A warewash machine includes a chamber for receiving wares, the chamber having at least one wash zone. A refrigerant medium circuit includes a first condenser and a second condenser, the first condenser located upstream of the second condenser in the refrigerant circuit. The refrigerant medium circuit includes a first flow path through the first condenser and a second flow path in bypass of the first condenser, and a valve for selectively controlling whether at least some refrigerant medium flows along the first flow path or the second flow path.
