Description

  The present invention relates to an air conditioner having a function of automatically cleaning an air filter provided at an air suction port of an indoor unit and an air cleaning function of removing fine dust in the air.

  In a conventional air conditioner filter device, an air filter is provided on the front surface of the heat exchanger to prevent dust from entering the inside of the main body of the air conditioner. It is configured to be detachable so that it can be cleaned. The filter device with such a configuration not only requires frequent maintenance, but the air filter gradually clogs until maintenance is performed, resulting in a reduction in the amount of air passing through the heat exchanger. However, the air conditioning capability is reduced, leading to an increase in power consumption.

For this reason, for the purpose of reducing the labor of maintenance of the air filter, an automatic cleaning device has been proposed in which the suction part moves and periodically cleans dust adhering to the air filter (see, for example, Patent Document 1). ).
