Description

  The present invention includes a rotary cleaning body that cleans a floor surface and the like, and a cleaning body that cleans an air filter attached to an air conditioner, a cleaning body that constitutes the rotary cleaning body, and a cloth thereof, and the rotary cleaning body. The present invention relates to a vacuum cleaner suction tool and an air conditioner, and an electric vacuum cleaner including the vacuum cleaner suction tool.

  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 air filter is moved by rotating the drive shaft. 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).
