Abstract

PURPOSE: To provide an electric blower used for a vacuum cleaner with an air guide having spiral air guiding elements formed on one of its surfaces to prevent an impeller from increasing its rotation when there is no air flow.
CONSTITUTION: An air guide 6 has on its upper surface a volute portion 11 designed to convert a dynamic pressure generated by an impeller 5 into a static pressure and on its lower surface an exhaust passage 12. On the upper surface of the air guide 6 facing the impeller 5, there is also provided an air guiding portion 13 formed with one or more spiral grooves. When there is no air flow, air around the impeller 5 is flowed, in correspondence with its rotation, toward a shaft 9 along the spiral air guiding portion 13, pressing the shaft 9 there and braking a motor 2. Accordingly, the impeller 5 is prevented from increasing its rotation an electric blower with this structure is given a wide range for the adjustment of its input.
