Zusammenfassung: | PURPOSE:To prevent excessively long continuation of ozon generation when an abnormal person detection signal is output by providing a control means which stops driving of an ozon deodorizing means when a person detection signal from a person detecting means continues over a prescribed time period. CONSTITUTION:When a person detecting part 3 detects a person, a fan 13 and an ozon generater 12 of a deodorizer 1 are started to operate. After driving, time elapse of a person detection signal is counted by a counter, and when a prescribed time elapses, the deodorizer 1 is stopped. By this, as ozon generation is automatically restricted within the prescribed time period even when a person detecting means is in trouble, possibility of making bad influence on persons due to an abnormal density of ozon can be eliminated. |
