A dishwasher includes a tub, a door, and a drying device configured to supply air to a washing space in the tub. The drying device includes a condensing duct disposed outside the tub, a cold air supply module that is disposed outside the tub and defines a heat exchange flow path part adjoining the condensing duct, and a fan configured to cause air flow in the condensing duct. The condensing duct includes an upstream portion communicating with the inlet port and extending above the inlet port and then downward, and a heat exchange portion connected to the upstream portion and extending downward to the heat exchange flow path part. A height of an upper end of the heat exchange flow path part is equal to or larger than a height of a lower end of the inlet port.

A dishwasher includes a tub, a door, and a drying device configured to supply air to a washing space in the tub. The drying device includes a drying duct that is disposed outside the tub and includes a condensing duct and a return duct, a fan configured to cause a flow of air in the drying duct, and a heater configured to heat the air in the drying duct. The condensing duct includes a first condensing duct connected to an inlet port configured to receive moist air from the washing space, and a second condensing duct disposed vertically below a bottom portion of the tub and connected to the first condensing duct. The return duct includes a return upstream end connected to the second condensing duct and a return downstream end connected to an outlet port configured to supply air to the tub.

A dishwasher includes a tub, a door, and a drying device disposed outside the tub. The drying device includes a condensing duct that faces an outer surface of the tub, that is in fluid communication with an inlet port defined at the tub, and that extends in a vertical direction and a first direction intersecting the vertical direction, and a fan configured to cause a flow of air in the condensing duct. The condensing duct includes an upstream portion in fluid communication with the inlet port, a downstream portion that is in fluid communication with the upstream portion and includes a bent portion disposed below the upstream portion, and a rib that is disposed inside the bent portion and extends across the bent portion, where the rib protrudes in a second direction that intersects the vertical direction and the first direction.

A dishwashing appliance includes a tub defining a wash chamber. The tub includes an inlet and an outlet. The dishwashing appliance also includes a drying system in fluid communication with the wash chamber. The drying system includes a heat pipe heat exchanger having a condenser section and an evaporator section. The evaporator section is downstream of the outlet. The condenser section is downstream of the evaporator section and upstream of the inlet. A thermoelectric assembly is in thermal communication with the heat pipe heat exchanger.

A dishwasher system for cleaning dishes may include a dishwasher tub configured to house dishes therein and run a dishwasher cycle, a door assembly configured to selectively seal the dishwasher tub, the door assembly including an inlet nozzle arranged on the inside of the door assembly, the inlet nozzle extending across the width of the door at the top of the door assembly to receive hot and moist air post wash from the dishwasher tub, and a duct fluidly connected to the inlet nozzle and configured to transfer the air through the door assembly and out an outlet nozzle during a drying phase of the dishwasher cycle prior to the door assembly being opened post-cycle.

A household dishwasher includes a dishwasher cavity for receiving items to be washed for treatment, and a structural unit sized to extend over at least half of a width of the household dishwasher. The structural unit includes an air outlet for blowing air out of the dishwasher cavity, an extensive slotted blow-out opening in an upper region of the structural unit, and a collecting tank in a lower region of the structural unit for collecting condensate.

A dishwasher includes a dishwasher cavity for treatment of items to be washed and an air outlet for blowing out air from a dishwasher cavity. The air outlet is arranged in a lower quarter of a height of the dishwasher and extends as a slotted outlet across at least two thirds of a width of the dishwasher. The air outlet includes a first air-guiding element designed for a targeted removal of air into a region in front of a front face of the dishwasher, with the first air-guiding element applying a downward component to outflowing air.

A household dishwasher includes a dishwasher cavity for processing items to be washed, a front panel attached to a front side of the household dishwasher, and an air discharge unit arranged in a lower quarter of a height of the household dishwasher and including an air outlet designed to discharge air from the dishwasher cavity and arranged in the lower quarter of the height of the household dishwasher. The air outlet extends as a slotted outlet over at least two thirds of a width of the household dishwasher. The air discharge unit is designed to be held indirectly or directly on the front panel via a retaining connection in such a way that the air discharge unit is detachable from the front panel when the front panel is dismantled.

A dishwashing appliance may include a cabinet, a tub, a pump, a spray assembly, a fluid recirculation duct, a cold water loop, a heat exchanger, and a tub fan. The fluid recirculation duct may extend from a path inlet to a path outlet to recirculate air within a wash chamber. The cold water loop may define a cold water nozzle 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. The heat exchanger may be mounted to the cold water loop outside of the fluid recirculation duct to cool water within the cold water loop. The tub fan may be configured to selectively motivate an airflow from the path inlet to the path outlet.

A dishwasher includes a dishwasher cavity for treatment of items to be washed, and an air outlet for blowing out air from the dishwasher cavity. The air outlet is arranged in a lower quarter of a height of the dishwasher and extends as a slotted outlet over at least two thirds of a width of the dishwasher. A connection located on a rear face of the air outlet introduces humid air into the air outlet and is designed to supply the introduced air to an air distributor for separating the supplied air into differently oriented sub-flows.
