<p>PURPOSE:To deodorize to meet the requirement and retain deodorizing function for a long time by generating ozone when the odor measuring result is beyond the given value N1, computing the time required for the odor volume rising to the given value N2 or over, determining ozone generation volume and preforming deodorizing. CONSTITUTION:A charged section 1 consisting of an electrical discharge wire 2 and a flat plate electrode 3 on the upper stream side and a dust collecting section 5 on the downstream side of air flow, and odor of sucked air is sensed by an odor sensing means 12. Also, whether the measuring result from the means 12 reaches the given value N1 or not is determined by an odor volume determining means 13, and ozone is generated by an ozone generating means 14 based on the determination of means 13. Further, when ozone is generated, the required time for an odor measuring signal rising up to the given value N2 is computed by an odor volume computing means 17, based on what is measured by the determination of the means 13, while ozone generation volume is determined by an ozone generation volume determining means 18 to correspond to said required time. As a result, the device can deodorize to correspond with requirement and its deodorizing function can be retained for a long time.</p> |
