  • Patent number: 7712183
    Abstract: An electric vacuum cleaner (1) of the invention is adapted for wipe off cleaning using a sheet wound about a rotary brush (25) incorporated in a suction device (10). In order to wind a sheet (50) around a periphery of the rotary brush (25), a brush motor (44) rotates the rotary brush (25) in a predetermined direction at a predetermined rotational speed. At the same time, suction force of an electric blower fan (42) is set to the lowest level. This achieves the following advantage in a case where a wet sheet is used as the sheet (50). During sheet winding, water and alcohol released from the wet sheet (50) can be prevented from being scattered on a surface (100) to be cleaned. Further, the released water and alcohol do not adversely affect the electric blower fan (42).

  • Patent number: 7374443
    Abstract: There are provided a flexible hose 6, a connection tube 7 in which one end is connected to the inner peripheral face of the flexible hose 6 from the end 10 of the flexible hose and another end is exposed outside of the flexible hose 6, and a mold resin 24 which fixes the flexible hose 6 and the connection tube 7 by being filled over from the outer peripheral face of the flexible hose 6 nearby the end of the flexible hose 6 to the outer peripheral face of the connection tube 7 which is exposed out of the flexible hose 6.

  • Patent number: 6460217
    Abstract: An electric cleaning device circulates exhaust air from an electric blower to a floor intake tool. The exhaust air passes through an exhaust guide, formed as one element, in a main cleaning device unit from the electric blower through a hose to the floor intake tool. The exhaust guide is a resilient unitary resin part with sufficient resilience to permit compression for installation. The springback of the exhaust guide seals the exhaust path against leakage.
