AIR CLEANING STRUCTURE USING PHOTOCATALYST FOR AIR CLEANER, AIR CLEANER INCLUDING AIR CLEANING STRUCTURE, AND PHOTOCATALYTIC FILTER USED IN AIR CLEANING STRUCTURE
PROBLEM TO BE SOLVED: To provide a structure for cleaning air using a photocatalyst, with which the effect of air cleaning due to a photocatalyst can be improved by efficiently radiating ultraviolet light, and which can be made thin and compact by restricting the overall thickness of the air cleaner.SOLUTION: A photocatalytic filter 2 is configured by disposing a plurality of photocatalyst-supporting plate-shaped portions 20 facing one another across gaps, where the gaps 21 serve as air flow passages 41. An ultraviolet light-radiating portion 3 is disposed in a position facing an end surface 22a and/or an end surface 22b among end surfaces of the plate-shaped portions 20, at a prescribed distance from the corresponding end surface, wherein the end surface 22a is on the side from which air enters the gap 21, and the end surface 22b is on the side from which air exits. Between the ultraviolet light-radiating portion 3 and the plate-shaped portion end surface 22a/22b is formed an air supply path 40 which takes in air from a side part substantially parallel to the end surface and supplies the air to the flow passages 41, or an air discharge path 42 which discharges air output from the flow passages 41 to a side part substantially parallel to the end surface.SELECTED DRAWING: Figure 6【課題】効率よく紫外線を照射して光触媒による空気清浄化作用を向上させ、空気清浄機全体の厚みの厚みを抑え、薄型コンパクト化が可能となる光触媒による空気清浄化構造を提供せんとする。【解決手段】光触媒が担持した複数の板状部２０を隙間をあけて対向配置し、この隙間２１を空気の流通路４１とする光触媒フィルタ２を構成し、各板状部２０の端面のうち、隙間２１への空気の入口側の端面２２ａ及び空気の出口側の端面２２ｂの少なくとも一方の側の端面に対向する位置に、所定距離離して紫外線照射部３を配置し、該紫外線照射部３と各板状部端面２２ａ／２２ｂとの間に、該端面に略平行な側方より空気を取り込み、流通路４１に供給する空気供給路４０、又は流通路４１から出た空気を前記端面に略平行な側方に排出する空気排出路４２を形成した。【選択図】図６
