ABSTRACT:
Disclosed herein is a drying machine or a drying machine with washing function. The drying machine or the drying machine with washing function comprises a heater for heating air introduced into an inlet channel of a drum, an outlet channel for allowing air in the drum to be discharged out of the drying machine or the drying machine with washing function therethrough, and a circulating channel connected between the outlet channel of the drum and the heater. When the exhaust resistance of air at the outlet channel is large, some of air, passing through the outlet channel, is guided to the heater through the circulating channel. Consequently, the drying machine or the drying machine with washing function according to the present invention has an effect in that air flow rate sufficient to dry the laundry is obtained and time necessary to dry the laundry is reduced.
