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.

Abstract: First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.
