PROBLEM TO BE SOLVED: To completely sterilize and surely deodorize with a convenient structure. SOLUTION: Upon generation of ozone in an ozone generating part 7, a damper 9 in an opening 3 is opened, and a fan 8 is opened so that the ambient air is sucked into an ozone generating part 7 thr, ozone is emitted into the outside through an opening 2. Ambient air containing emitted ozone is again sucked through the opening 3 and the damper 9, and is fed into the ozone generating part 7 and is emitted into the outside together with ozone which has been additionally generated, through the opening 3. With the repetitions of the above-mentioned process, the quantity of ozone is increased. After a predetermined time elapses while the rotation of the fan 8 is still continued. Thus, the ambient air is sucked through an opening 4, and dust, the odor of the ozone and the like are absorbed by a prefilter 10, ozone deodorizing catalyst 11 and an acid gas adsorbent 12, and clean air is emitted through the opening 2 through the fan 8 and the ozone generating part 7. |
