Abstract

The present disclosure relates to a dishwasher having a heat pump, including a dishwasher body provided with a tub configured with a washing space therein and a sump provided at a bottom of the tub to temporarily accommodate washing water; a heat pump having a compressor, an evaporator, an expansion apparatus, and a condenser provided on an inner bottom surface of the tub to exchange heat with washing water inside the tub; and a controller that controls the heat pump to be driven to increase the temperature of the washing water inside the tub. As a result, the heating time of washing water may be shortened.
