<p>PURPOSE:To contrive the maintenance of a deodorizer at longer intervals by detecting the odor amount of the air drawn in by an odor detecting means, judging whether or not the detected results exceed a predetermined value by an odor amount judging means, and, if they do, operating an ozonizing means for deodorization. CONSTITUTION:An electric charge part 1 consisting of a discharge wire 2 and a plate electrode 3 is provided on the upstream side of air flow and a dust collector 5 on the downstream thereof. An odor detecting means 11 detects the odor of the air drawn in and an odor amount judging means 12 finds out whether or not the signal from the means 11 exceeds a predetermined value. The discharge wire 2 produces ozone according to the judgement by the means 12. As a result, the deodorization can be effected as required and the deodorizer can be maintained at longer intervals.</p> |
