Description

  The present invention relates to an air filter cleaning device disposed in an air conditioner such as an air conditioner, a blower, a humidifier, a dehumidifier, a ventilation fan, or an air purifier, 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, 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. 6, for removing dust from the air filter, a cleaning piece 25 in which brush hairs 24 are planted on a base cloth 23 is spirally wound from the end of a cylindrical synthetic resin core rod 22. In addition, a rotary cleaning body 21 in which a cap 26 is attached to an end of the core rod 22 has also been used conventionally.
