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 washing water storage unit provided in the dishwasher body to store washing water therein; a heat pump having a compressor, an evaporator, an expansion apparatus, and a condenser provided to exchange heat with the washing water of the washing water storage unit; and a controller that controls the heat pump to increase the temperature of the washing water of the washing water storage unit. As a result, a heating time of washing water may be shortened, thereby suppressing a time required for washing dishes from being prolonged.
