摘要： 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.

摘要： 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.
