<P>PROBLEM TO BE SOLVED: To provide a photocatalytic deodorizing device, maintaining deodorizing performance for a long period by effectively exciting a photocatalyst on the whole surface of a photocatalyst sheet and having a long life. <P>SOLUTION: In the photocatalytic deodorizing device 1, base plates 5, 7 provided with a ventilation hole 4 are disposed parallel to each other, an LED 4 is mounted on at least one base plate 5 of the two substrates, the photocatalyst sheet 6 including a glass fiber woven fabric 6A carrying photocatalyst particles 6B and a frame 6C supporting the woven fabric is disposed between the two base plates, the photocatalyst sheet and the two substrates are fixed to a casing 8, the light emitting surface of the LED light source for exciting the photocatalyst and the photocatalyst sheet are disposed in parallel, and the air fed through the ventilation holes passes through the photocatalyst sheet. The photocatalyst sheet is formed by bundling together glass fibers, and weaving the same longitudinally and laterally to have a predetermined numerical aperture to enable ventilation at a low wind speed, and the photocatalyst particles are mechanically held in contact between the glass fibers of the photocatalyst sheet. <P>COPYRIGHT: (C)2011,JPO&INPIT |
