PHOTOCATALYTIC DEVICE AND FLUID PURIFYING APPARATUS INCLUDING THE PHOTOCATALYTIC DEVICE

摘要

Provided are a photocatalytic device 1 capable of further enhancing an effect on purification of fluid such as air by a photocatalyst and also efficiently dissipating heat emitted from a light applying portion, and capable of further enhancing the purification effect by increase of a light amount, and a fluid purifying apparatus including the photocatalytic device. Both end portions 321, 325 of an upper-side inner wall 32 of a housing 3 in the lateral direction are in contact with upper faces of both end portions, in the lateral direction, of a photocatalyst filter 2 to support the photocatalyst filter 2, and form upper-side edge portions for openings 3a, 3b. A center portion 323 of the upper-side inner wall 32 in the lateral direction is distant from an upper face of a center portion, in the same direction, of the photocatalyst filter 2 over a predetermined distance H1 in an upward direction. Tilted portions 322, 324 are positioned in regions between both the end portions 321, 325 and the center portion 323 of the upper-side inner wall 32 so that a distance in the upward direction between each of the tilted portions 322, 324 and the upper face of the photocatalyst filter is gradually increased from the both end portions toward the center portion. A lower-side inner wall 33 of the housing 3 covers a lower face of the photocatalyst filter, is in contact with the lower face of the photocatalyst filter 2 to support the photocatalyst filter 2, and forms lower-side edge portions for the openings 3a, 3b. A light applying portion 4 is disposed on a lower face of the center portion 323 of the upper-side inner wall 32.
