Abstract:
The present invention is provided to improve static pressure efficiency in an air blower provided with a fixed blade on the downstream side of a fan. The air blower includes: a fan which rotates in a predetermined direction around a rotational axis; and a plurality of fixed blades which are arranged radially around the rotational axis on the downstream side in the advancing direction of an airflow generated by the rotation of the fan and are curved in the opposite direction to the rotation direction of the fan from an inner circumferential part toward an outer circumferential part, wherein the fixed blades are configured in such a manner that an inlet angle formed between an inlet end through which the airflow flows and the rotational axis, and a chord angle formed between a chord connecting the inlet end to an outlet end through which the airflow is discharged and the rotating axis, are greater in the inner circumferential part and the outer circumferential part than in the radial center portion, and an outflow angle formed between the outlet end and the rotational axis is greater than 0° and less than 50°.

Claim (Index 1):
An outdoor unit of an air conditioner, comprising:\n an air blowing fan which rotates around a rotational axis; an air blowing fan housing which covers the air blowing fan; and a fixed blade which extends from the rotational axis side toward an inner circumferential surface side of the air blowing fan housing and comprises a curved shape curved along a radial direction of the air blowing fan, wherein the fixed blade comprises an inlet end disposed at a side into which an air current formed by the air blowing fan flows, an inner circumferential part disposed on a side of the rotational axis, an outer circumferential part disposed on a side of an inner circumferential surface of the air blowing fan housing, and a central part disposed between the inner circumferential part and the outer circumferential part, and wherein first inflow angles formed by the inlet end and the rotational axis at the inner circumferential part and the outer circumferential part are greater than a second inflow angle formed by a tangent of the inlet end and the inlet end and the rotational axis at the central part.
