  • Patent number: 6192550
    Abstract: A dust-collecting device for a vacuum cleaner comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, and a cylindrical filter fitted into the dust-collecting case. The filter is arranged to be rotatable, a spiral rib is formed at an outer periphery of the filter, and the device is equipped with a rotating means for rotating the filter. Dust which cannot be discharge by its own weight since it is in a compressed state can be pushed out through the spiral rib formed on the outer periphery of the filter by rotating the filter, so that dust accumulated within the dust-collecting case in a compressed state can be easily discharged.

  • Patent number: 6058559
    Abstract: An electric vacuum cleaner comprising a vacuum cleaner body, a hose to be connected to the vacuum cleaner body, a support pipe to be connected to the hose, and a suction device to be connected to the support pipe. The suction device is provided with running wheels, and the vacuum cleaner body is able to be detachably fastened to the support pipe so that it is supported by the wheels of the suction device when the vacuum cleaner body is attached to the support pipe. The cleaning workability is thus improved, and the external appearance of the vacuum cleaner body in a condition of being detached from the support pipe can be improved.
