  • Publication number: 20050160554
    Abstract: An electric vacuum cleaner 100 and a dust collecting unit 5 for use therein of the present invention include a dust collecting container 51 into which air sucked at the time of cleaning is led and a cyclone mechanism 52 for causing the air led into the dust collecting container 51 to swirl to separate dust contained in the air from the air, and are further provided with a filter 25 outside the dust collecting container 51 for catching minute dust contained in the air discharged from the dust collecting container 51. According to the electric vacuum cleaner 100 and the dust collecting unit 5 for use therein of the present invention, minute dust not removed from the air in the dust collecting container 51 by the cyclone mechanism 52 can be surely caught by the filter 25 provided outside the dust collecting container 51. And since the filter 25 is provided outside the dust collecting container 51, it has a preferable maintenance property for cleaning, exchange and the like.

  • Patent number: 5907889
    Abstract: A vacuum cleaner comprising: a main body having a dust collecting chamber and a motor chamber; a cover for the dust collecting chamber; and an inlet pipe formed on the dust collecting chamber. A lever is provided within the dust collecting chamber, the lever being swingable between a position where one end of the lever is positioned between an opening edge of the dust collecting chamber and the cover to prevent the cover from closing and a position where the lever enables the cover to close. It is not possible to attach the cover to the cleaner in the state where the dust collecting bag is detached so that it is possible to securely prevent misuse of the cleaner in the state where the dust collecting bag is not attached.
