PURPOSE:To keep the deodorizing capacity for a long period by forming a photcoatalyst layer on the surface of adsorbent, kneading a photocatalyst in an adsorbent, or using a photocatalyst to act as an adsorbent, and providing the light source to excite the potocatalyst. CONSTITUTION:A fan 4 is driven by a fan motor 8 and air is sucked from an air sucking-in opening 3c through a prefilter 3b and is deodorized by deodorant 5 and discharged through a fan cover 3a. The deodorant 5 is so made that the photocatalyst layer of TiO2 group is formed on the surface of honeycomb type activated carbon or the photocatalyst of TiO2 group is kneaded in activated carbon, or a photocatalyst to act as an adsorbent is used, and the photocatalyst is excited by an ultraviolet ray lamp 6 to decompose the odor components to be removed. |
