Abstract: The present invention relates to a blower. A blower according to an embodiment of the present invention comprises: a lower case having a suction hole in through which air flow; an upper case which is disposed at the upper side of the lower case and which has a discharge port through which the air is discharged; a fan motor for providing rotating force; and a fan disposed inside the lower case and fixed to a motor shaft of the fan motor, wherein the fan includes: a hub having an outer surface, which is extended to be inclined at a first angle with respect to the motor shaft; a plurality of blades coupled to the hub; and a shroud having an inner surface which is extended to be inclined, with respect to the motor shaft, at a second angle that is greater than the first angle, and which faces the outer surface of the hub with respect to the blade, and thus the air discharged from the fan can change into an ascending current.

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.
