  • Patent number: 8627531
    Abstract: When the electrically driven fan (14) of a vacuum cleaner is driven, air containing dust is drawn into the cleaner main body (1) through a hose (7) connected to a hose socket (8) and is exhausted into the outside of the cleaner main body (1) through an exhaust port (1b) via first and second suction passageways (10, 13). Disposed outside the first suction passageway (10) is an ion generator (23), it being arranged that plus and minus ions generated in the ion generator (23) are fed to the air stream flowing in the first suction passageway (10). Since the plus and minus ions kill floating germs in the air stream, the exhaust can be purified.

  • Publication number: 20070113373
    Abstract: A vacuum cleaner in accordance with the present invention is provided with a left cover 40 and a right cover 41, which cover a suction port body, so as to be movable in the right and left direction to facilitate cleaning by expanding the suction port body when the side of a wall, a corner of a room, and the like are cleaned. When the vacuum cleaner approaches a wall etc., the right cover 41 moves so as to project to the outside from a bumper 3. A part of the suction port body 2 expands to the side, and an expansion space A covered by the right cover 41 is formed on the right-hand side of the suction port body. Dust and dirt on a floor surface facing to this space are sucked through a main suction port 20. Also, side suction ports 34 made of a flexible material are communicatingly formed in both end portions at the right and the left of a dust suction chamber 18 of the suction port body 2 so that dust and dirt is also sucked through the side suction port 34 when the side of wall is cleaned.
