Abstract
A blower is provided that includes a lower case having a suction hole through which air flows into the blower; an upper case which is disposed at an upper side of the lower case and which has a discharge port through which the air is discharged from the blower; a fan motor that provides a rotational force; and a fan disposed inside of the lower case and fixed to a motor shaft of the fan motor. The fan includes a hub having an outer surface, which extends at an incline 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 extends at an incline, 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 plurality of blades, and thus, the air discharged from the fan may change into an ascending current.
