There is nothing. Therefore, when the second separation dust collecting unit 27 is irradiated with ultraviolet rays from the ultraviolet lamp 67, the ultraviolet rays are not blocked or diffused by the coarse dust, so that germs can be effectively removed by the ultraviolet rays.
  • the user since coarse dust is mainly collected in the first separated dust collecting portion 26, the user frequently removes the first separated dust collecting portion 26 from the main body case 25 and discards the dust inside. Since maintenance is performed, it is difficult for dust to accumulate inside for a long period of time, and propagation of germs and the like is relatively small.
  • the second separated dust collecting portion 27 is located at the rear stage of the first separated dust collecting portion 26 from which most of the dust has been removed, so that dust (fine dust) is difficult to collect and maintenance such as dust disposal is performed.

  • the dust collecting means 28 the amount of dust collected in the latter stage (downstream side) is small, and frequent maintenance is not required, and the dust tends to be accumulated over a long period of time. Therefore, by irradiating the second separated dust collecting portion 27 located on the downstream side with ultraviolet rays for sterilization (sterilization), it is possible for the dust collection means 28 as a whole to hardly propagate bacteria.
