摘要： 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.

摘要： A pump inlet assembly and method of operating a dishwasher appliance are provided. The pump inlet assembly includes an inlet conduit providing fluid communication between a sump and a pump. The inlet conduit defines an integrally formed boss which is coupled with a sensor housing using an overmolding process. A pressure sensor is positioned in the sensor housing and is protected from wash fluid by an airgap defined by the boss. The measured pressure may be used to determine the water level within the dishwasher when the pump is not operating and the suction pressure within the inlet conduit when the pump is operating. The inlet conduit, boss, pressure sensor, and pump housing may be integrally formed by injection molding and/or overmolding processes to reduce costs and the likelihood of leaks.

摘要： A dishwasher appliance includes a tub that defines a wash chamber for receipt of articles for washing. The dishwasher appliance also includes a lower spray assembly located in the wash chamber and configured to direct a spray of fluid into the wash chamber. The dishwasher appliance further includes an upper spray assembly located in the wash chamber above the lower spray assembly along the vertical direction. The upper spray assembly is configured to direct a spray of fluid into the wash chamber. A sump is positioned at a bottom of the wash chamber for receiving fluid from the wash chamber. The dishwasher appliance further includes a pump in fluid communication with the sump. The pump is configured to draw fluid from the sump. A main conduit extends between the pump and the upper spray assembly. The main conduit includes an upper end and a hole defined in the upper end.

摘要： A dishwasher appliance includes a sump that defines a transition fill level where the cross sectional area of the sump increases. A pressure sensor is operably coupled to the sump for monitoring sump pressure and wash fluid level. A controller opens a water supply valve to provide a flow of water into the sump and monitors the sump pressure using the pressure sensor. The controller determines when the water has reached the transition fill level corresponding to a known transition fill volume. The controller determines a fill flow rate based on the amount of time needed to reach the transition fill volume and uses the fill flow rate to determine a remaining fill time needed to reach a target volume.

摘要： A dishwasher or dishwasher door, as provided herein, may include an inner panel and a dispenser assembly. The inner panel may define a stamped hole extending along an aperture axis. The dispenser assembly may be mounted to the inner panel. The dispenser assembly may include a retaining cup, a radial lip, a flat compression gasket, and a discrete bracket. The retaining cup may have an interior surface defining an additive compartment and an exterior surface defining a relief outside of the additive compartment. The retaining cup may be positioned through the stamped hole. The radial lip may be joined to the retaining cup forward from the stamped hole. The flat compression gasket may be disposed about the retaining cup against a front surface of the inner panel. The discrete bracket may be held between a back surface of the inner panel and the relief of the retaining cup.

摘要： A dishwashing appliance and a spray assembly, as provided herein, may include a manifold body, and a cammed diverter valve. The manifold body may be mountable within a wash chamber. The manifold body may define a fluid inlet, a first spray zone, and a second spray zone. The first spray zone may include a first spray outlet. The second spray zone may include a second spray outlet spaced apart from the first spray outlet. The cammed diverter valve may be mounted within the manifold body and be movable between a first zone position and a second zone position. The first zone position may direct wash fluid to the first spray zone and restrict wash fluid to the second spray zone. The second zone position may direct wash fluid to the second spray zone and restrict wash fluid to the first spray zone.

摘要： A dishwashing appliance, as provided herein, may include a cabinet, a tub, a pump, a spray assembly, a fluid recirculation duct, and a cold water line. The tub may be housed within the cabinet and define a wash chamber. The fluid recirculation duct may extend from a path inlet to a path outlet to recirculate air within the wash chamber. The path inlet may be defined in fluid communication between the wash chamber and the path outlet. The path outlet may be defined in fluid communication between the path inlet and the wash chamber downstream from the path inlet. The cold water line may extend through the fluid recirculation duct. The cold water line may define a cold water nozzle that is disposed within the fluid recirculation duct to provide a condensing, cold-water flow into the fluid recirculation duct between the path inlet and the path outlet.

摘要： 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.
