Abstract
A clothes dryer capable of minimizing heat energy loss and increasing energy efficiency includes a cabinet, a drum provided within the cabinet, an exhaust duct through which air discharged from the drum is discharged out of the cabinet, an intake duct through which air is guided to the drum, a heating portion which heats air introduced into the intake duct, a heat exchanger provided within the exhaust duct and having a first heat exchange space in which air discharged from the drum exchanges heat with air introduced from the inside or outside of the cabinet into the exhaust duct, and a preheating member including a second heat exchange space through which air passing through the heat exchanger is guided to the intake duct so that air flowing into the intake duct via the heat exchanger exchanges heat with heat radiated from the intake duct in the second heat exchange space.
