Abstract: Disclosed is a hair dryer capable of improving convenience in handling, changing a temperature range of a blown air variously, and generating anions in the blown air. The hair dryer includes a manipulating panel (12) in which switches (S1,S2,S3,S4) are independently mounted, a first microprocessor (MPU1)(100) for transmitting an input signal input from each switch to a second microprocessor (MPU2)(200), and a second microprocessor (MPU2)(200) for controlling operation the driving motor according to the input signal and classifying a connection interval of electric current applied to the heating coil (C). The hair dryer allows a temperature range to be variously controlled, so the hair dryer may be utilized in more various fields, and because of using a single heating coil C, the hair dryer has very simple inner configuration, thereby reducing manufacture costs remarkably.
