While the supply air ventilation operation is stopped for the filter cleaning operation, the display unit 77 displays that the supply air ventilation operation is stopped. Then, in step S10, it is determined whether or not the filter cleaning operation is completed. When the filter cleaning operation is completed, the supply air ventilation operation is resumed in step S11.
• the filter cleaning operation is not performed even during the humidification operation or the air supply ventilation operation, which is not only during the temperature adjustment operation. This prevents the indoor heat exchanger 12 from being covered with the filter 21 and performing the humidification operation or the supply air ventilation operation in the state! As a result, it is possible to prevent an increase in the contamination of the indoor heat exchanger 12 due to air that has not passed through the filter 21 passing through the indoor heat exchanger 12.
• Another condition may be used as the filter cleaning operation start condition instead of the above condition. Another condition may be added together with the above condition. [0036] (2)
• the display unit 77 may be a power indoor unit 2 configured by a plurality of LEDs or a liquid crystal screen provided in the remote controller 81.
• the force using the wall-mounted indoor unit 2 may be used.
• the filter 21 reciprocates and the rotating brush 71 is operated during the forward path.
• the operation is not limited to these operation methods as long as dust on the filter 21 is removed.
• the rotary brush 71 is operated to clean, the filter 21 is partially reciprocated, the filter 21 is temporarily stopped to clean, and the rotational direction of the rotary brush 71 is reversed. It may be operated completely.
• the driving method of the filter 21 may be a driving method such as a force that reciprocates the belt drive.
• the present invention has an effect of preventing air from flowing without passing through a filter by a filter cleaning operation, and is useful as an air conditioner.
