Abstract: A blower includes a first tower and a second tower spaced apart from each other each having discharge ports that face each other. A gate is movably installed in at least one of the first tower or the second tower to protrude into and out of the space between the first and second towers to change a flow of air discharged out of the discharge ports. A guide motor may be configured to move the gate. The discharge ports may be provided at a rear side of the space to discharge air toward a front of the space, while the gate may be moved to cover the front side of the space to guide air upward.

Abstract: The present invention relates to a blower, the blower according to an embodiment of the present invention comprising: a lower case having a suction hole formed therein through which air is introduced; an upper case arranged on the upper side of the lower case and having a discharge hole formed therein through which air is discharged; and a fan arranged in the lower case and including a plurality of blades. Each of the plurality of blades includes a plurality of airfoils respectively extending along different camber lines from one another, and a leading edge of connecting the leading ends of the plurality of airfoils. Entrance angles formed by the respective camber lines of the plurality of airfoils and the rotation directions of the blades are different from one another. Thus, due to the curved shape of the leading edge and the design of a recessed notch, a flow separating from the leading edge is reduced, and thus, there is an advantage in that air volume performance is improved.
