Abstract: A dryer having a waste heat recovery device includes a cabinet, a drum rotatably mounted within the cabinet and having a front surface and a rear surface, an intake duct configured to provide an intake flow path through which air flows into the drum, an exhaust duct configured to exhaust air coming from the drum out of the cabinet, a heater configured to heat air flowing into the drum, and an ambient air duct configured to inhale air from outside the cabinet and supply the air from outside the cabinet into the drum. The waste heat recovery device includes an evaporation unit configured to absorb heat from air that is exhausted from the drum, a condenser unit configured to transfer heat absorbed from the evaporation unit to ambient air that flows into the ambient air duct, and a heat transfer medium configured to transfer heat between the evaporation unit and the condenser unit. The ambient air duct is configured to communicate air from the ambient air duct into the intake duct at a point along a flow path between the drum and the heater.
