Air discharge structure for vacuum cleaner, has resilient lever arranged in seating hole located adjacent to exhaust grille, for returning exhaust-grille cover to closed position when cleaner operation is stopped

摘要

A cover (110) arranged in a position corresponding to an exhaust grille (103), closes the grille when vacuum cleaner (100) is not operated. The cover allows air flow through the grille using back pressure of exhaust-air from the grille when the cleaner is operated. A resilient lever (121) arranged in seating hole (130) located adjacent to the grille, returns the cover to closed position when cleaner operation is stopped.
