PROBLEM TO BE SOLVED: To purify air in a small section without making an air curtain. SOLUTION: A suction port 23 and a discharge port 24 are made in the upper part and the lower part of the front plate of a box body 22 of an air purifier 21 respectively, and a discharge port 25 is made in the lower part of the back plate thereof. Inside the box body 22, a fan 26 is installed below between the upper and lower parts thereof and a dust collector 27 is installed above the fan 26 and a flow diverter 28 is installed below the fan 26. By action of the fan 26, contaminated air in front of the box body 22 is sucked in from the suction port 23 and is purified by a dust collector 27 and is diverted by the flow diverter 28 and is discharged from the first and the second discharge ports 24, 25. The purified air discharged from the first discharge port 24 flows along a floor surface 31c, and as it approaches to a side wall 31a, it rises and is sucked into the suction port 23 while catching smoke of cigarettes. |
