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 spray arm provided inside the washing space to spray washing water; a circulation pump that pumps the washing water of the sump; a washing water guide that guides the washing water pumped by the circulation pump to the spray arm; a heat pump provided with a compressor, an evaporator, an expansion apparatus, and a condenser provided to exchange heat in contact with the washing water of the washing water guide; and a controller that controls the heat pump to increase the temperature of the washing water of the washing water guide. As a result, it may be possible to suppress heat loss from being generated while heating washing water.
