  • the dirt receptacle unit 600 collects the dirt separated from the air in the dust-collecting unit 200.
  • the dust-collecting unit 200 comprises the first dust-collector 300 and a second dust-collector 400.
  • the first dust-collector 300 firstly separates dirt from the drawn-in air by using inertia and gravity.
  • the second dust-collector 400 is arranged around an outer circumference of the first dust-collector 300 and secondly separates minute dirt particles that are not yet separated from the air in the first dust-collector 300, by using centrifugal force.

  • the first housing 310 forms an exterior contour of the first dust-collector 300.
  • the first housing 310 comprises a first inlet 311 through which the air flows into the first housing 310 from the suction pipe 320 and a first outlet 312 through which the air is discharged to the outside of the first housing 310.
  • the suction pipe 320 has a curved shape such that the suction pipe 320 has a horizontal portion 321 and a vertical portion 322.
  • a part of the horizontal portion 321 protrudes from a second housing 410 of the second dust-collector 400, and the rest part of the horizontal portion 321 penetrates through the second housing 410 of the second dust-collector 400 and the first housing 310 of the first dust-collector 300.
  • the vertical portion 322 fluidly communicates with the horizontal portion 321 and extends downwards and towards the dirt receptacle unit 600 in parallel to a common axis 301 of the second housing 410 and the first housing 310.
  • An air suction port 321a is formed at the horizontal portion 321 to guide the air into the multi dust-collecting apparatus 100.

  • the vertical portion 322 is connected to the first inlet 311 to guide the air passed through the suction pipe 320 into the first housing 310.
  • the suction pipe 320 downwardly directs the dirt-laden air in the first dust-collector 300.
  • the dirt included in the descending air descends due to gravity and inertia and collides with a bottom surface 611 of the dirt receptacle unit 600, thereby being separated out from the air and collected in a first dust-collecting chamber 620.
  • the air separated from the dirt ascends due to suction force of a suction motor (not shown) disposed in a vacuum cleaner (not shown).
  • the suction pipe 320 penetrates through an upper center portion 313 of the first and the second housings 310 and 410 along the axis 301 of the first and the second housings 310 and 410.
  • the multi dust-collecting apparatus 100 does not require the suction pipe 310 or an air inflow port to be disposed at an upper side portion 314 of the first housing 310 to generate a centrifugal force. This is because according to the present invention the dirt is separated from the drawn-in air by the gravity and the inertia.

  • the first backflow prevention member 331 has a first inclination angle ⁇ 1 with respect to the first housing 310 and has a first opening 333 having a predetermine diameter D1. Due to the first inclination angle ⁇ 1, dirt particles piled on an upper surface 331a of the first backflow prevention member 331 slide down to the dirt receptacle unit 600. Meanwhile, a first air passing opening 335 is formed between an end 331 b of the first backflow prevention 331 and the vertical portion 322 of the suction pipe 320.
  • the second backflow prevention member 332 is disposed above the first backflow prevention member 331 and fixed to the first housing 310. Like the first backflow prevention member 331, the second backflow prevention member 332 may be adhered or welded to the first housing 310, or may be integrally formed with the first housing 310.
  • the second backflow prevention 332 has a second inclination angle ⁇ 2 with respect to the first housing 310 and has a second opening 334 having a predetermined diameter D2.

  • the air outflow guide channels 530 fluidly communicates with the second outlet 424.
  • the cover 510 may be integrally formed with the air inflow guide channels 520 and the air outflow guide channels 530, or may be fabricated separately from them.
  • the air discharge pipe 540 fluidly communicates with the air outflow guide channels 530 and guides the air discharged from the respective cyclones 420 through the air outflow guide channels 530 to the outside of the multi dust collecting apparatus 100.

  • the air drawn in through the suction pipe 320 descends and arrives at the bottom 611 of the first dust-collecting chamber 620.
  • Relatively large dirt particles have the tendency to keep descending due to the inertia and the gravity, so they collide with the bottom surface 611 of the first dust-collecting chamber 620 and are separated from the air.
  • the air separated from the dirt exits through the first air passing opening 335 and the second air passing opening 336 in sequence. At this time, the air-borne dirt collides with the first and the second backflow prevention members 331 and 332 and thus does not ascend. Rather, the dirt is separated from the air and drops down to the first dust-collecting chamber 620.
  • the air exiting from the second air passing opening 336 passes through the first outlet 312 and is guided to the air inflow guide channels 520. Then, the air flows into the respective cyclone chambers 421 through the second inlets 423 of the plurality of cyclones 420. Minute dirt particles are separated out by being centrifuged in the cyclone chambers 421 and collected in the second dust-collecting chamber 630 of the dirt receptacle unit 600.

  • the cleaned air is discharged to the outside of the multi dust-collecting apparatus 100.
  • the relatively large dirt particles are firstly separated out by using the gravity and the inertia and the relative minute dirt particles are secondarily separated out by using centrifugal force. Accordingly, compared to the conventional cyclone apparatus taking both the first and the second steps to separate dirt particles using the centrifugal force, a loss of suction force can be greatly reduced. Therefore, a power consumption can be reduced.
  • the backflow prevention member 330 is provided in the first dust-collector 300 separating the dirt firstly, it prevents the large dirt particles from flowing into the second dust-collector 400. Also, the plurality of cyclones 420 are provided in the second dust-collector 400 so that minute dirt particles collection efficiency can be improved.
