摘要： An electric blower includes an electric motor including a stator and a rotor. The impeller is rotated by the electric motor. An air guide having a plurality of guide blades is disposed around the impeller, and a casing encloses the impeller and the air guide. The casing is provided with a number of exhaust openings through which a part of an air stream suctioned by the impeller is discharged, and a circumferential length of each of the exhaust openings is substantially identical to a circumferential distance between outer peripheral ends of adjacent guide blades. Alternatively, the circumferential length of each of the exhaust openings may be less or greater than the circumferential distance between outer peripheral ends of adjacent guide blades.

摘要： An electric blower includes a motor unit having a stator and a rotor, a fan unit having an impeller attached to an output shaft of the rotor, and a circuit unit having a heat-generating component for controlling electric power to the motor unit. The circuit unit is arranged in an airflow path of air expelled from an outer periphery of the impeller toward the stator and the rotor of the motor unit. The air suctioned by rotation of the impeller cools the heat-generating component in the circuit unit before cooling the stator and the rotor.

摘要： An electric blower includes an electric motor having a rotating shaft and an impeller fixed to the rotating shaft for rotation. The impeller has a rear shroud fixed to the rotating shaft, a front shroud which faces the rear shroud and has an inlet hole to take in air, a plurality of blades disposed between the rear shroud and the front shroud, and an inducer which streamlines air flowing from the inlet hole and has a three dimensional-shaped vane. The inducer is formed separately from the blade and is disposed between the rear shroud and the front shroud, whereby an electric blower that is simple in structure, lower in clearance between parts, higher in strength, and lower in air loss is realized. Also, a practicable vacuum cleaner high in sucking performance is realized by the utilization of the electric blower.
