Definitions

  • the dust collector of a related art when more than a predetermined amount of dusts are stored in the dust collector while the vacuum cleaner is operating, the dust circulates and rises along an inner wall of the dust collector to invade the cyclone unit formed in an upper space of the dust collection body. Thus, the non-separated dust is discharged together with the air current through the outlet, thus lowering the dust collecting effectiveness of the dust collector.
  • the present invention is directed to a vacuum cleaner that substantially obviates one or more problems due to limitations and disadvantages of the related art.
  • Fig. 2 is a perspective view illustrating the dust collector separated from a dust collector receiving part applied to the vacuum cleaner.
  • Fig. 3 is a sectional perspective view of the dust collector.
  • Fig. 4 is an enlarged view of section "A" in Fig. 3 .
  • Fig. 5 is a perspective view illustrating a coupling relation between a driving apparatus for compressing dust stored in the dust collector and the dust collector.
  • the second press member 320 may be disposed between an inner circumferential surface of the dust storage part 221 and a rotating shaft 312 serving as a rotation center of the first press member 310.
  • the driving motor 430 may rotate the first press member 310 in the forward/reverse directions at a constant angular speed, in order to more easily compress the dust.
  • the first press member 310 When the first press member 310 rotates in the other direction (counterclockwise direction), the first press member 310 pushes the dust collected between the first and second press members 310 and 320 toward one side of the second press member 320, thereby compressing the dust.
  • the first press member 310 continuously rotates until the torque generated during the compression of the dust reaches the set value.
  • the air firstly purified by means of the main cyclone unit 211 passes through the exhaust member 211c and is discharged through the outlet 211b. Then the air flows into the auxiliary cyclone unit 140.
