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.
