PURPOSE:To prevent the adhesion of oxide to an ozone generator to certainly obtain deodorizing effect by providing a circulating passage for circulating a part of air treated with an ozone decomposing filter separated from a blower and the ozone decomposing filter and arranging the ozone generator to the circulating passage. CONSTITUTION:The offensive smell component contained in the air introduced from a suction port 1a by a blower 2 is reacted with ozone generated from an ozone generator 3 to be deodorized and the treated air is discharged from an exhaust port 1b and an ozone decomposing filter 4 having a catalyst decomposing ozone remaining in the air after deodorizing is provided. A circulating passage 10 for circulating a part of the air treated with the ozone decomposing filter 4 from the exhaust port 1b to the suction port 1a is provided separatedly from the blower 2 and the ozone decomposing filter 4 and the ozone generator 3 is arranged to the circulating passage 10. Therefore, a part of clean air subjected to ozone deodorizing treatment not containing a large amount of ammonia can always be used as ozone forming air. |
