Description

  The present invention relates to a filter device for an air conditioner that automatically cleans an air filter.

  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, an automatic cleaning device has been devised that periodically cleans dust adhering to the air filter with a brush, as in Patent Document 1, for the purpose of reducing the maintenance work of the filter.
