Abstract
A blower including a case; a fan; and a diffuser that is disposed downstream of the fan and guides air, discharged from the fan, toward discharge ports. The diffuser includes an outer wall; an inner wall spaced apart inwardly from the outer wall so that an air passage is formed therebetween; and a plurality of vanes that extends radially between the outer wall and the inner wall and divides the air passage into a plurality of unit passages. The outer wall and the inner wall are formed to have areas with different radial separation distances between the outer wall and the inner wall, such that in an area of the air passage of the diffuser in which air is discharged to a portion having a high flow resistance in the blower, the radial separation distance increases to widen the air passage, thereby compensating for asymmetry of the passage inside of the blower, allowing a uniform volume of air to reach an entire area of the discharge ports, and improving performance of the blower.
