Abstract
This blower apparatus includes an air blowing portion including a plurality of flat plates; a motor portion; and a housing. The housing includes an air inlet and an air outlet. Each of a top flat plate and intermediate flat plates among the flat plates includes an air hole and an air blowing region radially outside of the air hole. Since the air flow is generated between the flat plates, the air flow does not easily leak upwardly or downwardly, and thus, an improvement in air blowing efficiency is achieved. A radial middle of the air blowing region of at least one of the intermediate flat plates is arranged radially outward of a radial middle of the air blowing region of an upwardly adjacent one of the flat plates.
