That is, as described above, the entire region of the filter unit 20 in the second direction D2 is irradiated with the deep ultraviolet rays by the three irradiation units 33. Accordingly, the bacteria and viruses adhered to the filter unit 20 and the dust are killed (sterilized and disinfected).
  • the dust is likely to accumulate in the filter unit 20, and the filter unit 20 is likely to be clogged. Therefore, the dust is removed by the cleaning device 30.

In this way, the filter unit 20 can be efficiently sterilized and disinfected in accordance with the driving of the cleaning device 30.
  • the filter unit 20 is a photocatalyst filter. Since the filter unit 20 is the photocatalyst filter, the filter unit 20 can be autonomously sterilized and disinfected over time by being irradiated with the ultraviolet rays by the irradiation unit 33 in addition to the visible light emitted from indoor illumination or the like. That is, it is possible to achieve both the sterilization and disinfection of the filter unit 20 by the irradiation unit 33 and the self-cleaning action based on a photocatalyst effect of the filter unit 20. As a result, the filter unit 20 can be maintained in a cleaner state.
  • the plurality of irradiation units 33 are arranged at intervals in the second direction D2 orthogonal to the first direction D1, which is the reciprocating direction of the cleaning unit 32. Accordingly, the filter unit 20 can be sterilized and disinfected over a wider range in the first direction D1 and the second direction D2.
  • the UVC-LED that emits the deep ultraviolet rays as described above is generally expensive. Therefore, the number of the UVC-LEDs required can be reduced by disposing only the plurality of (for example, three) irradiation units 33 at intervals in the second direction D2 in this way. As a result, it is possible to reduce the manufacturing cost and the maintenance cost of the device.
  • the UVC-LED that emits the deep ultraviolet rays having a short wavelength is used as the irradiation unit 33.
  • the deep ultraviolet rays have an effect of fundamentally killing the bacteria and viruses by destroying genes of the bacteria and viruses. Therefore, the filter unit 20 can be maintained in an extremely clean state.
  • the irradiation unit 33 is provided adjacent to the first direction D1, which is the reciprocating direction of the cleaning unit 32.
  • the cleaning unit 32 reciprocates, first, on an outbound path, the sterilization and disinfection of the dust adhered to the filter unit 20 are performed, and the dust is removed by the brush unit 84. That is, the dust stored in the dust box 88 is already in a state of being sterilized and disinfected.
  • the filter unit 20 after the dust is removed can be directly sterilized and disinfected by the ultraviolet rays emitted by the irradiation unit 33, and at the same time, the photocatalyst effect can also be obtained. Accordingly, it is possible to reduce the possibility that the user comes into contact with the bacteria and viruses.
  • the irradiation unit 33 and the pedestal unit 83 are provided on the side opposite to a side where the drive motor 81a of the brush mechanism 82 is located.
  • the irradiation unit 33 and the pedestal unit 83 may be provided on the side where the drive motor 81a of the brush mechanism 82 is located.
  • the same actions and effects as described above can be obtained as the brush mechanism 82 reciprocates in the first direction D1. Which side of the brush mechanism 82 the irradiation unit 33 and the pedestal unit 83 are provided on may be appropriately selected as long as interference with the drive motor 81a does not occur.
  • a configuration in which the pedestal unit 83 is not provided can be adopted.
  • the irradiation unit 33 is directly fixed to an end surface of the brush mechanism 82 facing the first direction D1.
  • the irradiation unit 33 further includes a prism 100 for directing an irradiation direction of the irradiation unit 33 to the filter unit 20.
  • the filter unit 20 is the photocatalyst filter.
  • the UVC-LED capable of irradiating the deep ultraviolet rays is used as the irradiation unit 33, a certain sterilization and disinfection effect can be obtained by the irradiation unit 33 alone. Therefore, the filter unit 20 does not necessarily need to be configured with the photocatalyst.
  • the air conditioner described in each embodiment is understood as follows, for example.
  • the irradiation unit 33 is provided adjacent to the first direction D1, which is the reciprocating direction of the cleaning unit 32. In this manner, as the cleaning unit 32 reciprocates, on one of the outbound path or the inbound path, the sterilization and disinfection of the dust adhered to the filter unit 20 are performed. On the other of the outbound path or the inbound path, the filter unit 20 after the dust is removed can be directly sterilized and disinfected.
