Abstract
A blowing device is provided. The blowing device includes a first blowing unit that suctions air from above and discharges the air downward, and a second blowing unit disposed below the first blowing portion so as to suction air from below and to discharge the air upward. The blowing device is advantageous in that no matter what position the user is in, wind may be easily discharged to the user.
