Abstract: 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.

Abstract: A clothes treatment apparatus includes a cooling water pipe that is placed within a condensing duct to condense humidity contained in a circulating air current. The latent heat generated from the condensation of humidity causes the temperature of the cooling water in the cooling water pipe to rise. A thermoelectric pump mechanism collects heat from the higher-temperature cooling water and uses it in heating the circulating air.

Abstract: A dishwasher includes a tub, a door coupled to a front of the tub, and a drying device disposed at the door and configured to dry an inside of the tub. The drying device includes a bracket that defines a space configured to receive the wet air and the dry air, an impeller coupled to the bracket and configured to cause the wet air and the dry air to be mixed, where the impeller is configured to generate a flow of the mixed air. The drying device further includes a cover coupled to the bracket, and an air guide disposed between the bracket and the cover and configured to guide the flow of the mixed air into the impeller. The impeller is rotatably coupled to the air guide.

Abstract: A method controls a dishwasher including a tub configured to receive objects to be washed, a drying device configured to receive wet air from the tub and to discharge the wet air to an outside of the dishwasher, and a dry air supplier including a heating part and being configured to supply heated air to the tub. The method includes preheating the drying device by introducing dry air from the outside to the drying device before a first preset time from a start point of a drying operation, performing the drying operation at the start point, wherein the wet air is discharged from the tub during the drying operation, and cooling the dry air supplier by stopping operation of the heating part before a second preset time from an end time point of the drying operation.
