PROBLEM TO BE SOLVED: To rapidly guide contaminated air such as the smoke of cigaret in a room to the suction ports of a purifier main body by providing a divided flow outlet port for supplying purified air downward along the side surface of the purifier main body from a divided flow passage. SOLUTION: When a purifier main body 1 is turned on, contaminated air is sucked to the purifier main body 1 from a suction port 2 as shown by arrow marks B, dust is removed while it passes through a prefilter 9 and a dust collecting cell 8 and purified air is discharged through an exhaust port 6 as shown by arrow marks A from the outlet port 12 of a suction fan 7. At this time, a part of the air enters a divided flow passage 18 through a partition wall 13 and supplied downward from a divided flow outlet port 14. Then, the air flows as shown by arrow marks A' and flows again toward the lower part and and the suction port 2 of the purifier main body 1. This flow enables negative pressure to be increased from the lower part of the purifier main body 1 to its front part. Thus, the air flows together with the smoke of cigaret resident nearby toward the suction port 2 as shown by the arrow marks B, is sucked to the purifier main body 1 and purified. |
