Ductless type clothes drier

A ductless type clothes drier comprises: a heat pump system including a condenser (143) configured to supply hot air into the drum (120), and an evaporator (150) configured to remove moisture inside air exhausted from the drum (120); and a lint removing unit (400) configured to inject water to the evaporator (150) so that lint on the evaporator (150) can be removed. Accordingly, without using water, moisture included in exhausted air can be removed as a heat exchange process is performed at the evaporator (150). Water for removing moisture included in air does not have to be supplied to the ductless type clothes drier, thereby solving cost increase due to increase of a water consumption amount. Furthermore, since clean water remained after being used for heat exchange is not discarded, waste of water resources is prevented. Also, the conventional problem that the ductless type clothes drier has a difficulty in being commercialized due to increase of a water consumption amount is solved. Furthermore, since the lint removing unit configured to inject water to the evaporator is provided, lint on the evaporator (150) is removed. Accordingly, a heat exchange efficiency by the evaporator (150) is enhanced, and a drying function of the ductless type clothes drier is more enhanced.
