PURPOSE:To sharply prolong the life of a deodorizing device by constituting the deodorizing device of the 1st odor sensor, an ozonizer, a catalyst and the 2nd odor sensor and intermittently operating the ozonizer. CONSTITUTION:Let the odor value in an inlet of a deodorizing device measures by the 1st odor sensor be A1 and let the odor value of air after passing through a catalyst measured by the 2nd sensor be A2, then when A1 exceeds an reference B1 equivalent to the allowable odor value and the value obtained by the formula, (A1-A2)/A1, is not more than a reference B2, odor components on the catalyst is deodorized with ozone by operating the ozonizer and when the value by (A1-A2)/A1 exceeds the reference B2, the ozonizer is stopped. |
