PROBLEM TO BE SOLVED: To provide an air cleaner capable of discharging the air from a discharge port to the front of a cleaner body without increasing the flow resistance of the discharge port which is the cause of air quantity reduction and increase of noise. SOLUTION: A pressure difference between the air discharge upward from the discharge port 7 and the air on the inclined plane 1a of a cleaner body case 1 is generated, and the flow along the inclined plane 1a is caused by Coanda effect in the air discharged from the discharge port 7, and the air from the discharge port 7 can be discharged toward the front of the cleaner body case 1 by providing such discharge port 7 in which gratings 6 are formed integrally at the top surface of the cleaner body case 1 and providing such inclined plane 1a lowering with a depression angle of 40-50 deg. toward the rear side of the cleaner body case 1 at the front of the discharge port 7. |
