PROBLEM TO BE SOLVED: To provide an air conditioner having a filter cleaning function of automatically cleaning dust on the filter, and preventing accumulation of dust on blades of a fan. SOLUTION: The air conditioner comprises a suction exhaust device 6 sucking dust collected by the filter (not shown in the figure) disposed upstream of a heat exchanger (not shown in the figure), through a suction nozzle (not shown in the figure). The suction exhaust device 6 is formed of a motor 11 rotating a cross flow fan 12, and a fan casing 9 covering the cross flow fan 12 and having a suction casing part 10 having a suction port 18, and a blowoff port 15. The suction port 18 communicates with the suction nozzle, and the blowoff port 15 communicates with the outdoors through an exhaust duct 8. Since dust on the filter is automatically eliminated and discharged outdoors, maintenance is easy, and suction performance is not degraded since dust is not accumulated on the blades 12a because of a self-cleaning function of the cross flow fan 12.
