发明名称 ELECTRIC VACUUM CLEANER
摘要 A rotating brush including a hollow cylindrical rotor having through holes in it s peripheral wall and bristles on its peripheral surface is provided in a nozzle o f an upright electric vacuum cleaner. A reflux passage connecting a fan chamber in th e cleaner body and an end of the rotor is provided so that a slip stream of an ele ctric fan for producing a suction stream jets out into the nozzle from the rotor through t he holes. A fan for sucking air outside the nozzle is provided at the other end of the rot or so that the sucked air also jets out into the nozzle through the holes. In another elect ric vacuum cleaner, the rotor of the rotating brush is not provided with through hol es but the slip stream of the electric fan is caused to blow the peripheral surface of the rotating brush from its end.
