Abstract: A blower includes a housing through which air is introduced, a plurality of discharge ports disposed above the housing, each having a discharge port, and facing each other, a blowing space formed to be spaced at least partly between the plurality of discharge departments facing each other and open at least front and rear, a ground disposed on a downstream side of the blowing fan, spaced downward from the plurality of discharge departments, and connected to the housing, and a supporter extending upward from the ground to support the plurality of discharge departments. Accordingly, it is possible to improve blowing performance of the blower by reducing the occurrence of vortex through a pressure buffer zone formed by vertical separation of the ground and the discharge department, and structural stability of the blower can be improved by supporting the discharge department by the supporter and ground disposed inside the housing.
