PROBLEM TO BE SOLVED: To hold an air filter provided in an air conditioner unit in a cleaned state and to eliminate necessity of a cleaning operation by providing a means for moving to circulate the filter at a predetermined amount each time an air conditioner is operated for a predetermined time, and a means for automatically cleaning the filter. SOLUTION: An operating lapse time of the air conditioner is integrated by a controller. When its integrated value becomes a predetermined set value, a rotation start signal is output from the controller to a motor 15, and the motor 15 is rotated. Then, a drive gear 11 is rotated to move an air filter 10. Moving gears 12, 13, 14 also rotate as the filter 10 moves. Simultaneously, a gear 19 fixed to the gear 11 is rotated. A gear 20 fixed to a shaft of a cleaning brush 16 is rotated to rotate the brush 16, thereby cleaning contaminant of the filter. Simultaneously, the controller outputs a rotation signal to a dust collecting motor 18 to rotate a fan 17, thereby collecting dust removed by the brush 16. |
