とを特徴とする電動送風機。 An electric blower comprising: an electric motor built into a blower body; a suction fan attached to a rotating shaft of the motor to suck air from an intake port; and a discharge port to discharge air inside the blower body to the outside. The main body is provided with an exhaust cover that covers the outer peripheral surface including the discharge port, and the exhaust cover includes a rectifying plate that rectifies air in one direction along the outer peripheral surface of the blower main body from the discharge port to the exhaust port of the exhaust cover. 1. An electric blower characterized in that the exhaust cover has a sound insulating material attached to an inner wall surface of the exhaust cover for absorbing rotational noise of the electric motor.
