Abstract
A dryer includes a hollow casing, a fan disposed inside the casing so as to cause air to be introduced into the casing and to be discharged therefrom, a heater disposed inside the casing to heat the air introduced into the casing by the fan, and a discharge tube including an inlet into which the air is introduced, and an outlet from which the air is discharged. The fan includes a first fan and a second fan, which rotate in opposite directions about an imaginary axis shared by the first and second fans. A discharge amount or a discharge rate can be controlled in a stepwise manner. The discharge tube is disposed inside the casing so as to be rotated in at least one direction, thereby diffusely discharging drying air to a region desired to be dried.
