第三實施方式中,例如,流體殺菌裝置1B在流路3a的兩端具有光源單元5-1、5-2。由此,根據第三實施方式,例如,通過具有兩個光源單元5-1、5-2,而與具有一個光源單元5-1、5-2的情況相比,水的殺菌能力進一步提高。In the third embodiment, for example, the
另外,第三實施方式中,設為具有兩個光源單元的構成,但光源單元的個數不受限定。例如,也可具有三個或三個以上的多個光源單元。In addition, in the third embodiment, the configuration has two light source units, but the number of light source units is not limited. For example, there may be three or more light source units.
(第四實施方式) 圖8是表示第四實施方式的流體殺菌裝置的主要部分的剖視圖。另外,圖8省略主要部分以外的圖示。第四實施方式在流體殺菌裝置1C中,由流路部件3形成的流路3a的內徑S1、和流路3a與光源單元5C的第一連結部51C的流路51a-1的連接部分的內徑S2滿足S1>S2。(Fourth embodiment) Fig. 8 is a cross-sectional view showing a main part of a fluid sterilization device of a fourth embodiment. In addition, FIG. 8 omits illustration other than the main part. In the fourth embodiment, in the
如圖8所示,流入到流體殺菌裝置1C內的水如圖示的箭頭那樣,在流動於流路3a而到達與流路3a連接的流路51a-1時,流路51a-1與流路3a的連接部分的內徑S2小於流路3a的內徑S1,因而使水集中於流路51a-1附近而提高紫外線的照射效率,並且在該連接部分附近產生水的對流(漩渦),光源6出射的紫外線向對流的水照射更長的時間。由此,根據第四實施方式,能夠抑制作為殺菌對象的水因通過紫外線的照射弱的部位而殺菌效果降低的情況,紫外線無遺漏地照射到水,從而效率佳,且進一步提高殺菌效果。As shown in FIG. 8, when the water flowing into the
(第五實施方式) 圖9是表示第五實施方式的流體殺菌裝置的主要部分的剖視圖。另外,圖9省略主要部分以外的圖示。第五實施方式中,在流體殺菌裝置1D中,由流路部件3形成的流路3a的內徑S1、和流路3a與光源單元5D的第一連結部51D的流路51a-3的連接部分的內徑S3為S1>S3的關係。進而,從流路51a-3向外方延伸的流路51a-4在離開紫外線透光部件7的方向上偏移規定距離。(Fifth Embodiment) Fig. 9 is a cross-sectional view showing a main part of a fluid sterilization device of a fifth embodiment. In addition, FIG. 9 omits illustrations other than the main parts. In the fifth embodiment, in the
如圖9所示,流入到流體殺菌裝置1D內的水,如圖示的箭頭那樣流動於流路3a而到達與流路3a連接的流路51a-3時,流路51a-3與流路3a的連接部分的內徑S3小於流路3a的內徑S1,進而,從流路51a-3向外方延伸的流路51a-4與紫外線透光部件7偏移規定距離。因而,使水集中於流路51a-3附近而提高紫外線的照射效率,並且在該連接部分及紫外線透光部件7附近產生水的對流(漩渦),光源6出射的紫外線向對流的水照射更長時間。由此,根據第五實施方式,能夠進一步防止作為殺菌對象的水因通過紫外線的照射弱的部位而殺菌效果降低的情況,紫外線無遺漏地被照射到水,從而效率佳,且進一步提高殺菌效果。As shown in FIG. 9, when the water flowing into the
