とする電動送風機。[Claims for Utility Model Registration] A stator having a stator core with an approximately rectangular outer shape, and a cylindrical portion arranged at the opening edge of one end of the cylindrical portion housing the rotor disposed inside the stator. Airflow that is formed between the case main body formed with an annular flat portion projecting outward, the inner surface of the cylindrical portion, and the outer surface of the stator core that is placed with the corner portions in close contact with this inner surface. a case that radially traverses the one end opening of the case body and is disposed between a pair of stator windings of the stator, and that both ends are fixed to the annular flat part. with end plate. This case has a fan attached to the rotor shaft that passes through the bearing support provided in the center of the case end plate, multiple air inlets around the periphery, and multiple rectified air channels connected to these air inlets on the inner surface. a rectifying plate that is formed between the fan and the opening at one end of the case body, is provided to cover the opening at one end, and guides the wind discharged from the fan into the case body; , In an electric blower equipped with this rectifier plate and a fan cover that covers the fan and is attached to the opening side of one end of the case body, both ends overlapping the annular flat part of the case end plate and a central bearing are provided. An electric blower characterized in that a through hole is provided between the support portion and the case end plate to communicate the cold rectifying air path with the air path inside the case body.
