Abstract:
A fan includes a motor, an impeller fixed to the motor, and a housing including a cylindrical inner circumferential surface. The impeller includes a plurality of blades extending radially outward. The housing is arranged to surround outer peripheries of the motor and the impeller. The housing includes an intake port which is an upper opening of the housing, an upper edge which surrounds the intake port, an exhaust port which is a lower opening of the housing, a lower edge which surrounds the exhaust port. An axial distance from an upper end of each of the blades to an upper edge is ½ times or more of an axial distance from the upper end of each of the blades to a lower end thereof. This makes it possible to restrain an air flow having a swirling component from passing through the intake port.

Claim (Index 1):
A fan comprising:\n a motor that rotates about a center axis extending up and down; an impeller including a plurality of blades extending radially outward, the impeller being fixed to the motor; a housing that surrounds outer peripheries of the motor and the impeller, the housing including a cylindrical inner circumferential surface, a plurality of ribs that interconnect the motor and the housing; and a cover including an outer wall portion disposed radially outward of the housing, wherein the housing includes an intake port which is an upper opening of the housing, an upper edge which surrounds the intake port, an exhaust port which is a lower opening of the housing, a lower edge which surrounds the exhaust port, and a flow straightening grid disposed in the upper edge, the flow straightening grid is disposed radially inward of the outer wall portion.
