An open loop drying system includes an intake conduit and an exhaust conduit. The intake conduit and the exhaust conduit are each in fluid communication with an ambient environment. The open loop drying system also includes a heat pipe heat exchanger. The heat pipe heat exchanger includes a condenser section in operative communication with the intake conduit upstream of a wet chamber and an evaporator section in operative communication with the exhaust conduit downstream of the wet chamber. The open loop drying system may be provided in a dishwashing appliance.

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 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 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 dish treating appliance can include a tub at least partially defining a treating chamber and having an access opening providing access to the treating chamber, a closure selectively closing the access opening, a condenser including an inlet, an outlet, and a condensing passage defining a serpentine path with multiple turns fluidly coupling the inlet and the outlet, with the inlet fluidly coupled to the treating chamber, the outlet fluidly coupled to ambient air, and multiple ambient air inlets provided in the serpentine path, and a blower fluidly coupled to the condenser flowing a volume of air through the serpentine path of the condenser, and at least one separator wall located within the condenser.

A dishwasher configured for drying dishes with the dishwasher having a tub at least partially defining a treating chamber and a closed loop condensation system for extracting liquid from air within a treating chamber of the dishwasher and a controller configured to control the dry cycle for drying of the dishes in the treating chamber of the dishwasher.

A dishwashing appliance includes a cabinet, a cabinet door for opening and closing the cabinet, a tub provided in the cabinet, the tub defining a wash chamber, an outlet defined at a first portion of the tub, an inlet defined at a second portion of the tub, an air flow duct defined between the inlet and the outlet, wherein air enters the air flow duct from the tub via the outlet and exits the air flow duct to the tub via the inlet, and an access panel removably attached to the air flow duct, the access panel defining a mounting plate protruding from an interior surface of the access panel.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

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 warewash machine includes a chamber with a wash zone and front, left and right access openings. At least one spray arm is disposed to spray liquid toward the wash zone. A multi-sided hood assembly is movable between a lowered and closed position for washing and a raised open position for inlet and outlet of wares. An air exchange system is provided for extracting hot water vapor from the chamber and for providing heated air into the chamber.
