PURPOSE: To ensure effective deodorization in shortened time by pumping pressurized air to the ozone generator and blowing out a large amount of air containing ozone with a blower set on the outlet.

CONSTITUTION: Pump 1, fan 2 and ozone generator 3 are connected to the power source in parallel. The pressurized air is fed through pump 1 and tube 10 to the ozone generator 3 where ozone of high concentration is formed. The ozone is sent through vinyl tube 11 and blown out into the chamber with the fan 2. The fan 2 sucks the air in the chamber, too and the ozone is diluted with the air. The chamber contaminated with bad smells can be deodorized in a shortened time.
