  • the blower 4 is driven by operating the switch 45 , with the grip 26 A being gripped.
  • the dust-laden air is sucked from the suction opening 34 a by driving the blower 4 so that it flows into the outlet passage 41 via the intake passage 40 , so as to be exhausted from an outlet (not shown) formed at the cleaner body 1 .
  • the flectional portion 35 is formed at the upper end of the suction tube 32 , facing the dust collecting section 16 of the dust collection container 11 , the air inside the dust collecting section 16 is guided by the flectional portion 35 to turn into a vortex airflow along the inside and outside annular walls 13 , 14 of the dust collection container 11 .
  • the cover 26 is opened by releasing the engagement of the hook 48 with the locker claw 48 A through the operation of the operation button 46 . Thereafter, the filter case 17 and the dust collection container 11 are taken off. Then, the dust collected in the dust collecting section 16 is thrown away into a trashcan while the dust captured by the filter 12 is removed. Thus, the filter case 17 is detachable from the dust collection container 11 , so that the maintenance of the filter 12 can be simplified.
  • the dust collecting section 16 is formed annular, and is arranged in a manner that surrounds the outside periphery of the electric motor 2 and fan 3 , the dust separated by the filter 12 is collected in the dust collecting section 16 while the air from which the dust is cleared away is sucked by the fan 3 surrounded by the dust collecting section 16 to thereby be exhausted outward.
  • the annular formation of the dust collecting section 16 enables the effective collection and large stowage of dust.
  • the installation of the filter 12 at the inner peripheral side of the dust collecting section 16 permits dust sucked by the rotation of the fan 3 to be filtered by the filter 12 provided at the inner peripheral side of the dust collecting section 16 , while the air from which the dust is cleared away is allowed to take a short course to flow to the fan 3 through the filter 12 , so that a compact arrangement of the dust collecting section 16 becomes possible around the electric motor 2 and the fan 3 to enable the cleaner body 1 to be down-sized.
  • the filter 12 is formed along the entire inner periphery of the dust collecting section 16 , the dust contained in the airflow F formed by the rotation of the fan 3 is filtered over the whole area of the filter 12 formed along the entire inner periphery of the dust collecting section 16 , thus ensuring the collection of the dust.
  • the airflow F flowing along the peripheral direction of the dust collecting section 16 is generated, whereby the dust-laden air sucked inside the dust collecting section 16 rotates along the outer periphery of the dust collecting section 16 so that the dust particles of greater size are pressed against the inside wall of the outer peripheral side of the dust collecting section 16 due to a centrifugal force and thus part of the dust particles are removed from the airflow F to be separated, while the dust particles of smaller size are sucked and thus only such smaller dust particles are filtered by the filter 12 provided at the inner periphery of the dust collecting section 16 , thereby preventing the filter 12 from being clogged.
  • the present invention should not be limited to the foregoing embodiment but various modifications are possible within the scope of the present invention.
  • a shape of the flectional portion 35 serving as a vortex airflow generation member or a basic structure of a vacuum cleaner such as a mounting structure of the filter 12 may be suitably selected according to needs.
  • the portable type vacuum cleaner is described in the foregoing embodiment, the present invention is also applicable to other types of vacuum cleaners.
