ULTRAVIOLET IRRADIATION DEVICE AND WASHING TOILET SEAT DEVICE
To provide the ultraviolet irradiation device capable of suppressing deterioration of constituent parts and flow paths of the ultraviolet irradiation device by ultraviolet rays.SOLUTION: The ultraviolet irradiation device 40 used for water sterilization comprises: a main body 41 into which water flows in from a water inlet 43a formed in an inflow part 43 and in which the water flows out from a water outlet 44a formed in an outflow part 44; an irradiation part 45 that is provided inside the main body for irradiating the water flowing through the inside with the ultraviolet rays; a reflecting part 46 that is provided so as to cover an inner wall of the main body and reflects the ultraviolet rays with a higher reflectance than the inner wall of the main body; and a shielding part 49 that shields at least one of the inflow part and the outflow part from the irradiation part.SELECTED DRAWING: Figure 3
【課題】紫外線照射装置の構成部や流路が紫外線によって劣化するのを抑制することができる紫外線照射装置を提供する。【解決手段】水の殺菌に用いられる紫外線照射装置４０は、流入部４３に形成された流入口４３ａから内部に水が流入し、流出部４４に形成された流出口４４ａから内部の水が流出する本体４１と、本体の内部に設けられ、内部を流通する水に紫外線を照射する照射部４５と、本体の内壁を覆うように設けられ、本体の内壁よりも高い反射率で紫外線を反射する反射部４６と、流入部および流出部の少なくとも一方を照射部に対して遮蔽する遮蔽部４９とを備える。【選択図】図３
