Description

  The present invention relates to a rotary cleaning body of an air conditioner for cleaning an air filter attached to the air conditioner, and an air conditioner using the same.

  In a conventional air conditioner, an air filter is disposed between the suction port and the heat exchanger to prevent dust from entering the air conditioner body, and air flows from the suction port as the air conditioner operates. 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, a disk-shaped air filter, a rotating brush in contact with the surface of the air filter, and a drive unit for rotating the air filter are provided, and the drive unit is driven. There is an air conditioner in which dust accumulated on the surface of an air filter is scraped by rotating a rotary brush while rotating the air filter (see, for example, Patent Document 2).

JP 2005-140405 A JP 2006-71121 A

  However, in the conventional air conditioner disclosed in Patent Literature 1, the suction pressure is increased by reducing the air volume by reducing the opening / closing area of the suction port. If you try to remove dust with such a suction nozzle, you can easily suck cotton dust and the like that floats on the surface of the air filter. In addition, dust containing oil and the like cannot be scraped off and removed like a cleaning brush, and it is very difficult to reliably remove dust stuck to the air filter.

  Further, in the conventional air conditioner disclosed in Patent Document 2, the brush hairs planted on the entire outer periphery of the rotating brush core are of the same type and the same length, and the dust is brush hair. Since the rotating brush becomes dirty, the air filter becomes dirty and the cleaning effect is reduced.
