A multi-purpose drier is provided to prevent frequent troubles of a PCB(Printed Circuit Board) by automatically cooling down the air during circulating the air by driving of an impeller, by disposing the PCB near the external air inflow part. In a multi-purpose drier, a front body(1a) has a first external air inlet port(3) formed on the lateral side and a mounting unit(4) formed on one side of the front part. A rear body(1b) is disposed at the rear side of the front body and composed of a second external air inlet port(7) formed on the lateral side and a first semicircle-shaped pipe(9) installed at one side of the inner part. A middle body(2) is installed at the rear body, equipped with a blowing unit(14), and provided with a second semicircle-shaped pipe(15). A PCB(20) is disposed at the position adjacent to the first external air inlet port and equipped with a timer. A connecting unit is detachably connected to a pipe body combined with the first and second pipes, and a bellows tube. A fixing unit(5) is arranged in the mounting unit of the front body to function as a switch. An ejection port member is connected to the connecting unit by the bellows tube. The other end of the ejection port member is installed at the mounting unit. The ejection port member is turned on or off by the fixing unit according to the installation state of the mounting unit.
