And has a function of catching intruding dust. For this reason, the dust caught on the air filter gradually adheres and the eyes gradually clog and reduce the air volume. It had to be sucked and cleaned with a vacuum cleaner.

  On the other hand, a suction nozzle having a suction port that can move along the upstream surface of the air filter, and a suction device connected to the suction nozzle are provided in the air conditioner body, and the air filter surface extends from the suction port. A structure has been devised that can automatically clean the air filter without removing the air filter by sucking the dust adhering to the surface (see, for example, Patent Document 1).

For the purpose of reducing the maintenance work of the filter, an air filter on the belt stretched around the drive shaft and a rotating brush in contact with the surface of the air filter are provided, and the drive shaft is rotated to move the air filter. However, there is an air conditioner in which dust accumulated on the surface is scraped by rotating a rotating brush (see, for example, Patent Document 2).

Further, as shown in FIG. 10, for removing dust from the air filter, a cleaning piece 64 in which brush bristles 63 are planted on a base cloth 62 is spirally wound from the end of a cylindrical synthetic resin core rod 61. In addition, a rotary cleaning body 60 in which a cap 65 is attached to the end of the core rod 61 has also been used conventionally.
