The operation of the air blowing unit 15 for blowing the outdoor air into the drying chamber 7 constituted by 4 can be performed by operating only the air blowing means 8 for the entire drying process or by using both the air blowing means 8 and the heating means 9 for the entire drying process. Or the first half of the drying process is operated only by the air blowing means 8 and the second half of the drying process is operated by both the air blowing means 8 and the heating means 9 to select the course. This realizes a clothes dryer that can efficiently dry clothes stored in the storage 7.
