<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner capable of carrying out automatic suction cleaning of an air filter by a small low-output suction device. <P>SOLUTION: The air conditioner is provided with the suction device connected to a suction nozzle 3 (not shown in the figure)capable of moving along the air filter (not shown in the figure). The suction nozzle 3 has an opening 21, and a suction hole change-over plate 23 arranged with suction holes 22a-22d in deviated states. The whole face of the air filter is cleaned by sequentially changing over sucking suction holes 22a-22d by moving the suction hole change-over plate 23 on the opening 21 every time the suction nozzle 3 is moved along the air filter. Since a sucking portion is limited to a portion of the suction holes 22a-22d overlapping the opening 21, a suction air capacity can be reduced while exercising strong suction force, and the suction device 6 needs only small power. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
