A drum structure of a drier is provided to promptly dry laundry by widening the heat transfer area by the hot wind supplied into a drum. In a drum(210) structure of a drier, annular prominences and depressions(202) are repetitively formed in a drum to widen the heat transfer area. The annular prominences and depressions are formed in the drum of the drier. The inner and outer surfaces of the drum form wrinkle shapes. The annular prominences and depressions of the drum are alternately formed in the longitudinal direction of the drum and are formed along the circumference of the drum. |
