US 4,904,289 A · Deodorizing apparatus

Abstract

A deodorizing apparatus includes a case having an air inlet and an air outlet, an ozone generator of the discharge type disposed in an air flow channel between the air inlet and the air outlet, an acceleration device disposed in the air flow channel at the air outlet side thereof for accelerating the decomposition of odors and ozone, a fan provided within the case, an electric motor provided within the case for driving the fan, and device disposed in the air flow channel at the air inlet side thereof for preventing an excess of ozone from flowing out. As a result, odors can be efficiently removed by a decomposition with ozone, while the leakage of residual ozone is minimized.
