Further, air containing dust sucked into the suction nozzle by the suction input is sucked into the dust collection unit 200 along a predetermined flow path formed inside the connecting pipe and the cleaner body 100. The

  Further, if air containing dust is sucked into the dust collecting unit 200, dust is primarily separated from the sucked air inside the dust collector 210. The separated dust is collected inside the dust collector 210, while the air from which the dust is separated is discharged from the dust collecting unit 200 and flows into the cleaner body 100, and the cleaner. The cyclone separating unit 300 flows into the main body 100 through a connecting flow path.

  In addition, the air flowing into the cyclone separating unit 300 separates dust again, and the separated dust flows into the dust collecting unit 200 and is collected. On the other hand, the air from which the dust has been separated flows along a predetermined flow path inside the cleaner main body 100 and is finally discharged to the outside through the main body discharge portion.

  2 is a cross-sectional view taken along the line II ′ of FIG.

  As shown in FIG. 2, the vacuum cleaner 10 according to the idea of the present invention is a process in which at least a part of the outer surface of the cyclone separator 300 is covered with a cover member 310 and dust is separated by the cyclone separator 300. It is configured to reduce generated vibration and noise.

  The cyclone separator 300 includes at least one or more small cyclones 301 arranged in parallel so that the air discharged from the dust collection unit 200 is separated into each small cyclone 301 and flows into the cyclone.

  Here, FIG. 2 shows that four small cyclones 301 are provided, but it is clarified that the idea of the present invention is not limited to the number of small cyclones.

  Specifically, since dust-containing air sequentially flows inside the dust collection unit 200 and then flows into the cyclone separation unit 300, the dust collection unit 200 and the cyclone separation unit 300 are connected in series. I understand that

  Meanwhile, the air discharged from the dust collection unit 200 moves to the cyclone separator 300 through a predetermined connection channel, and is divided at the inlet of the cyclone separator 300 as shown in FIG. It flows into the cyclone 301. In addition, the air flowing into each small cyclone 301 is separated from dust inside.

  That is, after the air exhausted from the dust collection unit 200 passes through one of the small cyclones 301, it does not pass through the other small cyclones 301, but simultaneously passes through the small cyclones 301. Inflow.

  Therefore, in the present embodiment, it can be clearly seen that the cyclone separator 300 is a plurality of small cyclones 301 having the same function.

  As shown in FIG. 3, the cover member 310 according to the present embodiment covers the outer side of the cyclone separator 300 at a position separated from the cyclone separator 300. Accordingly, a predetermined space 302 is formed between the cyclone separating unit 300 and the cover member 310.

  In addition, a plurality of noise reduction grooves 312 that reduce noise generated in the process of separating dust in the cyclone separation unit 300 are formed on the inner surface of the cover member 310.

  That is, the sound is a wave corresponding to a longitudinal wave, and such a sound hits the wall surface and repels. If noise generated in the cyclone separation unit 300 is projected to the noise reduction groove 312, the noise Since it is trapped in the reduction groove 312 and disappears or is absorbed in the noise reduction groove 312 or is diffusely reflected to cancel each other, a noise reduction effect can be obtained.

  Therefore, according to the present embodiment, noise is primarily blocked by the space 302 between the cover member 310 and the cyclone separator 300, and noise is secondarily reduced by the noise reduction groove 312. Since the noise is thirdarily blocked by the member 310, the noise can be reduced and blocked more effectively.
