  • Patent number: 7276099
    Abstract: An object of the present invention is to provide an electric vacuum cleaner equipped with a compact and easy-to-operate cyclonic separation type dust collector. To accomplish the object, the present invention mounts a cyclonic separation cylinder (104) that centrifugally separates and captures dust and a dust collecting case (105) that contains a first auxiliary filter (106) detachably on the lower case (101) of the cleaner body (1) and part of air from the cyclonic separation cylinder (104) is fed to the motor-driven blower through the dust collecting case (105). The present invention mounts a cyclonic separation cylinder (104) that centrifugally separates and captures dust and a dust collecting case (105) that contains a first auxiliary filter (106) detachably on the lower case (101) of the cleaner body (1) and part of air from the cyclonic separation cylinder (104) is fed to the motor-driven blower through the dust collecting case (105) and a filter provided under it.

  • Patent number: 7207083
    Abstract: The electric vacuum cleaner is disclosed which includes a main body within which an electric blower and cyclonic separation cylinder are provided. A dust collecting case is provided in communication with the cyclonic separation cylinder to receive dust that has been separated from the inlet tube. The dust collecting case also includes a lifter arranged therein. Air received from the inlet tube is separated such that a portion is passed through the dust collecting case and a communicating passage. The air is subsequently merged and discharge through the electric blower.
