Document Type and Number:
WIPO Patent Application WO/2023/002765
Kind Code:
A1
Abstract:
[Problem] To provide a photocatalyst unit that makes it possible to efficiently irradiate a photocatalyst with UV light and improve the fluid cleaning effect of the photocatalyst, that can be reduced in thickness and size as a photocatalyst unit formed from a photocatalyst filter and a light irradiation unit, and that also has a high degree of design freedom as pertains to channel structure and can obtain a sufficient cleaning effect overall without increasing the amount of light or increasing number. [Solution] A photocatalyst carrier is a blower fan-like or crossflow fan-like impeller, or an impeller of a blower fan or a crossflow fan. An impeller 4 has a pair of connecting plates 42, 43 that connect each blade plate 41 at both ends thereof in the direction of an axial center 40. The blade plate 41 and the connecting plates 42, 43 are fixed in a state in which a portion of an end part of the blade plate penetrates through a through groove formed in the connecting plate and protrudes therefrom, and the protruding part curves in a direction that intersects the axial center direction and that is parallel to the surface of the blade plate so as to be pressure fitted to an opening edge part of the through groove of the connecting plate.
