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.

Abstract: Air conditioner is provided that may include a case having an inlet and an outlet provided below the inlet, a heat exchanger configured to heat exchange external air introduced into the case through the inlet, a blower fan disposed below the heat exchanger and configured to be rotated by a rotational shaft formed in a lateral direction so as to send air inside the case from the inlet to the outlet, a lower guide that guides air, which is blown toward a lower side of the blower fan by the blower fan, to the outlet, an upper guide spaced apart from the lower guide to form a discharge passage with the lower guide, and a sterilization device disposed at one side of the lower guide and having a sterilization lamp configured to emit ultraviolet light toward the blower fan. A lower end of the sterilization lamp may be disposed lower than an upper surface of the lower guide.
