  • Patent number: 7559963
    Abstract: A vacuum cleaner includes a suction port assembly, a motor generating a suction force at the suction port assembly, and a cyclone dust collecting device for centrifugally separating air drawn in through the suction port assembly and the motor in sequence. The cyclone dust-collecting device includes an air discharge port penetratingly formed on an outer circumference of the cyclone dust-collecting device and exposed to an outside of the cleaner body, for guiding the air discharged to the outside. Accordingly, since the air discharge port is disposed in the cyclone dust collecting device, not in the cleaner body, a discharge channel for connecting the cyclone dust collecting device and cleaner body is omitted and thus a structure of the vacuum cleaner becomes simplified.
