すようにしたものである。After the deodorizing device 1 is driven, the presence or absence of a human body detection signal is further examined in step S3. If there is no signal, the deodorizing device 1 is turned off in step S5, and if the signal continues, step S4
Then, the elapsed time T is counted by a counter (not shown), and it is determined in step S6 whether or not a predetermined time T 0 has elapsed,
The process returns to S3 or the operation of the deodorizing device 1 is stopped in step S7. Then, in step S8, the examination of the presence / absence of human body detection is repeated.

止される。By the control operation as described above, the normal operation of the human body detecting unit 3 is not affected by the deodorizing unit 1 for a predetermined time as shown in FIG.
Although it operates for a time T less than T 0 , as shown in FIG. 5, when the signal becomes T> T 0 due to an abnormality in the human body detection unit 3, the operation of the deodorization unit 1 is automatically performed by the control unit 4. Therefore, the ozone generation is stopped at a predetermined time T 0 , and the abnormal ozone generation is prevented.
また、これらの異常がなくなったあとは、実際の人間の
使用時間Ｔに対応してＴ＜T0の任意時間の作動を繰返す
ことになる。Further, after these abnormalities disappear, the operation for an arbitrary time T <T 0 is repeated corresponding to the actual use time T of the human being.
