Box 9. As shown in FIGS. 1 and 2, the upstream side of the fluid sterilization device 1 is connected to the pump 12 and the flow path member 23 connected to the water supply tank 8 via a connection member 22 such as a joint. Furthermore, in the fluid sterilization device 1, the downstream side is connected to the flow rate adjustment mechanism 14 and the flow path member 25 communicating with the recovery tank 9 via a connecting member 24 such as a joint, similarly to the upstream side.

流體殺菌裝置1例如在飲用水供給裝置中被用於對供水箱8內的水進行殺菌處理。本實施方式中，作為流體，例如適用於自來水等的水。The fluid sterilization device 1 is used, for example, in a drinking water supply device to sterilize the water in the water supply tank 8. In this embodiment, as the fluid, for example, it is applied to water such as tap water.

如圖2所示，流體殺菌裝置1具有連結部2、形成作為第一流路的流路3a的流路部件3、蓋4、及光源單元5。As shown in FIG. 2, the fluid sterilization device 1 has a connecting portion 2, a flow path member 3 forming a flow path 3a as a first flow path, a cover 4, and a light source unit 5.

連結部2經由連結部件22而與流路部件23連結，形成利用泵12使來自流路部件23的水流入到流體殺菌裝置1內的流路。流路部件3為與連結部2連結且在流體殺菌裝置1內形成作為殺菌對象的水的流路3a的筒狀部件。The connection portion 2 is connected to the flow path member 23 via the connection member 22 to form a flow path through which the pump 12 allows water from the flow path member 23 to flow into the fluid sterilization device 1. The flow path member 3 is a cylindrical member that is connected to the connecting portion 2 and forms a flow path 3a of water to be sterilized in the fluid sterilization device 1.

流路部件3優選由紫外線反射率高且無紫外線引起的劣化的原材料所形成，本實施方式中，使用在透明的石英管的整個外表面形成紫外線反射率高的反射部3b的部件。反射部3b為使從後述的光源單元5出射的紫外線在流路部件3的流路3a內反射的反射部件的一例，例如為二氧化矽膜。The flow path member 3 is preferably formed of a material having high ultraviolet reflectance and no deterioration caused by ultraviolet rays.

The reflection portion 3b is an example of a reflection member that reflects ultraviolet rays emitted from the light source unit 5 described later in the flow path 3a of the flow path member 3, and is, for example, a silicon dioxide film.

另外，形成於流路部件3的反射部3b不限於二氧化矽膜，也可為形成於透明的石英管的整個外表面的鋁蒸鍍膜。而且，流路部件3不限於透明的石英管，也可為高反射率的聚四氟乙烯（polytetrafluoroethylene：PTEF，四氟乙烯的聚合物）等氟樹脂。而且，反射部3b也可不形成於流路部件3的外表面，而形成於整個內周面。In addition, the reflection part 3b formed on the flow path member 3 is not limited to a silicon dioxide film, and may be an aluminum vapor-deposited film formed on the entire outer surface of a transparent quartz tube. In addition, the flow path member 3 is not limited to a transparent quartz tube, and may be a fluororesin such as polytetrafluoroethylene (PTEF, a polymer of tetrafluoroethylene) with high reflectivity. Moreover, the reflection part 3b may not be formed on the outer surface of the flow path member 3, but may be formed on the entire inner peripheral surface.

蓋4為從流路部件3的外周覆蓋該流路部件3的筒狀部件。The cover 4 is a cylindrical member that covers the flow path member 3 from the outer periphery of the flow path member 3.

光源單元5具有第一連結部51、第二連結部52、光源6、及紫外線透光部件7。第一連結部51具有作為第二流路的流路51a-1、流路51a-2。第一連結部51及第二連結部52由導熱率為大於或等於規定的母材、例如腐蝕性強的不銹鋼形成。然而，第一連結部51及第二連結部52不限於不銹鋼，也可為導熱率高的鋁的複合原材料，還可為陶瓷或填充了填料的高導熱率樹脂等。The light source unit 5 has a first connecting portion 51, a second connecting portion 52, a light source 6, and an ultraviolet light transmitting member 7. The first connecting portion 51 has a flow path 51a-1 and a flow path 51a-2 as the second flow path. The first connecting portion 51 and the second connecting portion 52 are formed of a base material having a thermal conductivity greater than or equal to a predetermined value, for example, highly corrosive stainless steel. However, the first connecting portion 51 and the second connecting portion 52 are not limited to stainless steel, and may be a composite material of aluminum with high thermal conductivity, ceramics, filler-filled high thermal conductivity resin, or the like.

流路51a-1位於第一連結部51的中心附近，與流路3a連接。流路51a-2與流路51a-1連接，從第一連結部51的中心向外方延伸。第一連結部51與流路部件3及蓋4連結，將流路3a、流路51a-1及流路51a-2連接。The flow path 51a-1 is located near the center of the first connecting portion 51 and is connected to the flow path 3a. The flow path 51a-2 is connected to the flow path 51a-1, and extends outward from the center of the first connecting portion 51. The first connecting portion 51 is connected to the flow path member 3 and the cover 4, and connects the flow path 3a, the flow path 51a-1, and the flow path 51a-2.

第二連結部52具有作為第二流路的流路52a-1、流路52a-2、及位於由流路52a-1及流路52a-2包圍的區域的凹狀的光源收容部52b。第二連結部52在光源收容部52b中收納光源6，例如在光源收容部52b的開口部由紫外線透光部件7覆蓋的狀態下與第一連結部51連結，從而將流路52a-1與流路51a-2連接。The second connecting portion 52 has a flow path 52a-1 as a second flow path, a flow path 52a-2, and a concave light source accommodating portion 52b located in an area surrounded by the flow path 52a-1 and the flow path 52a-2. The second connecting portion 52 houses the light source 6 in the light source housing portion 52b, and is connected to the first connecting portion 51 in a state where the opening of the light source housing portion 52b is covered by the ultraviolet light transmitting member 7, thereby connecting the flow path 52a-1 with The flow path 51a-2 is connected.

而且，第二連結部52經由連結部件24而與流路部件25連結，形成使已經由底下所述流路的水經由流量調整機構14而向流體殺菌裝置1外流出的流路，即，經由與流路3a連接的紫外線透光部件7的中心附近的流路51a-1、朝向光源收容部52b的外周的流路51a-2、通過光源收容部52b的外周附近的流路52a-1、在光源6的發光面的相反面側從光源收容部52b的外周到中心附近的流路52a-2。Furthermore, the second connecting portion 52 is connected to the flow path member 25 via the connecting member 24, and forms a flow path that allows the water that has flowed from the flow path below to flow out of the fluid sterilization device 1 via the flow adjustment mechanism 14, that is, through The flow path 51a-1 near the center of the ultraviolet light transmitting member 7 connected to the flow path 3a, the flow path 51a-2 toward the outer periphery of the light source housing portion 52b, the flow path 52a-1 near the outer periphery passing through the light source housing portion 52b, The flow path 52a-2 is from the outer periphery of the light source housing portion 52b to the vicinity of the center on the side opposite to the light emitting surface of the light source 6.

光源6為在基板61上安裝著出射紫外線的LED（Light Emitting Diode）元件62（以下簡單表述為“LED 62”）的模組。基板61將金屬材料作為母材而形成。基板61上，雖未圖示，但隔著絕緣層而形成著所需的導電圖案（配線圖案），在導電圖案上設置著LED 62。另外，基板61不限於金屬材料，例如也可將氧化鋁等陶瓷作為母材。而且，光源6所具有的發光元件不限於LED 62，也可為鐳射二極體（Laser diode，LD）等其他半導體元件。The light source 6 is a module in which an LED (Light Emitting Diode) element 62 (hereinafter simply referred to as “LED 62”) that emits ultraviolet rays is mounted on a substrate 61. The substrate 61 is formed using a metal material as a base material. Although not shown in the figure, a required conductive pattern (wiring pattern) is formed on the substrate 61 via an insulating layer, and the LED 62 is provided on the conductive pattern. In addition, the substrate 61 is not limited to a metal material, and for example, ceramics such as alumina may be used as a base material. Furthermore, the light-emitting element included in the light source 6 is not limited to the LED 62, and may be other semiconductor elements such as a laser diode (LD).

光源6從未圖示的電源被供給電力，使LED 62發光。光源6配置成LED 62的發光面側與在流路3a內流動的水的前進方向相向的位置關係，例如光源6的基板61相對於流路3a為大致垂直面，對在流路3a內流動且靠近光源6的水照射LED 62的發光所產生的紫外線。換句話說，搭載於光源單元5的光源6的發出紫外線的方向與流動於流路3a（第一流路）的流體的流動方向大致相向。此處，“LED 62的發光面側”不僅表示LED 62的發光面，還意味著LED 62放出光的方向整體，即，除基板61上未設置LED 62的方向外的方向。而且，“光源6的發出紫外線的方向與流動於流路3a的流體的流動方向大致相向”不僅限定於完全地相向，還例如意味著容許光源6的發出紫外線的方向與流動於流路3a的流體的流動方向所成的角度（銳角）達±10°。The light source 6 is supplied with electric power from a power source not shown in the figure, and causes the LED 62 to emit light. The light source 6 is arranged in a positional relationship where the light-emitting surface side of the LED 62 faces the advancing direction of the water flowing in the flow path 3a. And the water close to the light source 6 irradiates the ultraviolet rays generated by the light emission of the LED 62. In other words, the direction in which the light source 6 mounted on the light source unit 5 emits ultraviolet rays is substantially opposed to the flow direction of the fluid flowing in the flow path 3 a (first flow path). Here, "the light-emitting surface side of the LED 62" means not only the light-emitting surface of the LED 62, but also the entire direction in which the LED 62 emits light, that is, a direction other than the direction in which the LED 62 is not provided on the substrate 61. Moreover, "the direction of the light source 6 emitting ultraviolet rays and the flow direction of the fluid flowing in the flow path 3a are substantially opposed to each other" is not limited to completely facing each other, but also means that, for example, the direction in which the ultraviolet light emitted by the light source 6 is allowed to be opposite to the flow direction of the fluid flowing in the flow path 3a. The angle (acute angle) formed by the flow direction of the fluid reaches ±10°.

另外，光源6的基板61不限於相對於流路3a為大致垂直面的位置關係，只要相對於流動於流路3a的水為相向的位置關係，則可為任一位置關係。而且，LED 62優選在殺菌效果相對高的波長275 nm附近具有波峰（peak）波長，但只要為具有殺菌效果的波長區域，則可使用任一者。In addition, the substrate 61 of the light source 6 is not limited to the positional relationship of a substantially vertical plane with respect to the flow path 3a, and any positional relationship may be adopted as long as it is opposed to the water flowing in the flow path 3a. Furthermore, the LED 62 preferably has a peak wavelength near the wavelength of 275 nm where the sterilization effect is relatively high, but any one may be used as long as it is a wavelength region having a sterilization effect.

紫外線透光部件7為相對於光源6，即，基板61大致平行配置的具有紫外線透光性的板狀部件，以對在流路3a內流動且靠近光源6的水照射光源6所出射的紫外線的方式使紫外線透過。The ultraviolet light transmitting member 7 is a plate-shaped member having ultraviolet light transmitting properties arranged approximately parallel to the light source 6, that is, the substrate 61, and irradiates the ultraviolet light emitted by the light source 6 to water flowing in the flow path 3a and close to the light source 6 The way to make ultraviolet light through.

從光源6出射的紫外線透過紫外線透光部件7，對在流路3a內流動的水照射來自光源6的直射光，並且如圖2所示的箭頭那樣，在流路3a內由反射部3b反射而對在流路3a內流動的水間接地照射來自光源6的反射光。The ultraviolet light emitted from the light source 6 passes through the ultraviolet light transmitting member 7, and irradiates the water flowing in the flow path 3a with direct light from the light source 6, and is reflected by the reflection part 3b in the flow path 3a as shown by the arrow in FIG. On the other hand, the reflected light from the light source 6 is indirectly irradiated to the water flowing in the flow path 3a.

而且，如圖3所示，從流路部件23形成的流路向流體殺菌裝置1內流入的水，如圖示的箭頭那樣，在流路3a內流動，且經由流路51a-1、流路51a-2、流路52a-1、流路52a-2，而向流體殺菌裝置1外的流路部件25形成的流路流出。向流體殺菌裝置1內流入的水在通過流路51a-2、流路52a-1、流路52a-2的路徑時，奪去收容於光源收容部52b的光源6發出的熱，並向流體殺菌裝置1外流出。Furthermore, as shown in FIG. 3, the water flowing into the fluid sterilization device 1 from the flow path formed by the flow path member 23 flows in the flow path 3a as shown by the arrow in the figure, and passes through the flow path 51a-1 and the flow path. The flow path 51a-2, the flow path 52a-1, and the flow path 52a-2 flow out to the flow path formed by the flow path member 25 outside the fluid sterilization device 1. When the water flowing into the fluid sterilization device 1 passes through the path of the flow path 51a-2, the flow path 52a-1, and the flow path 52a-2, it deprives the heat of the light source 6 contained in the light source housing portion 52b and sends it to the fluid. The sterilization device 1 flows out.

即，流路3a中已由從光源6出射的紫外線的照射而殺菌的水，從在光源6的發光面側形成於發光面的直行方向上的流路3a向發光面方向的流路51a-1流入，且在光源單元5內通過流路51a-1、流路51a-2、流路52a-1、流路52a-2的多個路徑，而向發光面的相反面側流出。將光源單元5內的流路51a-1、流路51a-2、流路52a-1、流路52a-2的多個路徑設置於包圍光源6的周邊，流體從光源6的發光面側向相反面側穿行。由此，光源6無須使用其他冷卻手段，使用通過流路51a-1、流路51a-2、流路52a-1、流路52a-2的多個路徑的水，雖間接但能夠有效率地冷卻。而且，無須使用其他冷卻手段，使用通過流路51a-1、流路51a-2、流路52a-1、流路52a-2的多個路徑的水來進行光源6的冷卻，由此無須設置例如鰭片（fin）等其他冷卻部件。由此，能夠實現流體殺菌裝置1的小型化。That is, the water sterilized by the ultraviolet rays emitted from the light source 6 in the flow path 3a flows from the flow path 3a formed on the light emitting surface side of the light source 6 in the straight direction of the light emitting surface to the flow path 51a in the direction of the light emitting surface. 1 flows in, passes through a plurality of paths of the flow path 51a-1, the flow path 51a-2, the flow path 52a-1, and the flow path 52a-2 in the light source unit 5, and flows out to the side opposite to the light emitting surface. The multiple paths of the flow path 51a-1, the flow path 51a-2, the flow path 52a-1, and the flow path 52a-2 in the light source unit 5 are arranged around the periphery of the light source 6, and the fluid flows from the light emitting surface side of the light source 6 Walk on the opposite side. Therefore, the light source 6 does not need to use other cooling means, and uses water passing through multiple paths of the flow path 51a-1, the flow path 51a-2, the flow path 52a-1, and the flow path 52a-2, which is indirect but can be efficiently used. cool down. Moreover, no other cooling means is required, and water passing through multiple paths of the flow path 51a-1, the flow path 51a-2, the flow path 52a-1, and the flow path 52a-2 is used to cool the light source 6, thereby eliminating the need to install For example, other cooling components such as fins. As a result, the size of the fluid sterilization device 1 can be reduced.

另外，宜在收容於光源收容部52b的光源6與光源收容部52b之間設置導熱率為大於或等於規定的導熱部件，例如宜為鋁、不銹鋼等。In addition, it is desirable to provide a thermally conductive member having a thermal conductivity greater than or equal to a predetermined value between the light source 6 housed in the light source accommodating portion 52b and the light source accommodating portion 52b, for example, aluminum, stainless steel, or the like.

另外，流體殺菌裝置1內水流動的方向不限於圖3所圖示的方向，也可為與圖3相反的方向。即，從形成著流路部件25的流路向流體殺菌裝置1內流入的水，也可經由流路52a-2、流路52a-1、流路51a-2、流路51a-1而在流路3a內流動，並向流體殺菌裝置1外的流路部件23形成的流路流出。而且，圖2及圖3中，由流路部件3形成的流路3a設為相對於光源單元5的光源6的發光面大致垂直，但不限於垂直，也可為對光源6的發光面，具有規定的角度的構成或者取自由角度的構成。In addition, the direction of the flow of water in the fluid sterilization device 1 is not limited to the direction illustrated in FIG. 3, and may be a direction opposite to that in FIG. 3. That is, the water flowing into the fluid sterilization device 1 from the flow path forming the flow path member 25 may also flow through the flow path 52a-2, the flow path 52a-1, the flow path 51a-2, and the flow path 51a-1. It flows in the passage 3a and flows out to the flow passage formed by the flow passage member 23 outside the fluid sterilization device 1. In addition, in FIGS. 2 and 3, the flow path 3a formed by the flow path member 3 is set to be substantially perpendicular to the light emitting surface of the light source 6 of the light source unit 5. However, it is not limited to being vertical, and may be the light emitting surface to the light source 6. A configuration with a predetermined angle or a configuration with a free angle.

（流體殺菌裝置的主要部分的I-I剖面（A方向）） 圖4是從A方向觀察第一實施方式的流體殺菌裝置的主要部分中的相對於流體流動的方向正交的I-I剖面的剖視圖。(I-I cross-section (A direction) of the main part of the fluid sterilization device) FIG. 4 is a cross-sectional view of the I-I cross-section perpendicular to the direction of fluid flow in the main part of the fluid sterilization device of the first embodiment viewed from the A direction.

即，圖2及圖3中，如果在圖示的A方向上觀察I-I剖面，則如圖4所示，出現第二連結部52及光源6。圖2及圖3中，在圖示的A方向上觀察I-I剖面的情況下，如圖4所示，第二連結部52為圓狀，在其中心附近具有凹狀的光源收容部52b。而且，在光源收容部52b中，將在基板61上安裝LED 62而成的光源6以光源6的紫外線照射方向為流路3a側的方式收容。而且，在光源收容部52b的周圍設置著多個流路52a-1。That is, in FIGS. 2 and 3, if the I-I cross section is viewed in the direction A as shown in the figure, as shown in FIG. 4, the second connecting portion 52 and the light source 6 appear. In FIGS. 2 and 3, when the I-I cross-section is viewed in the direction A shown in the figure, as shown in FIG. 4, the second connecting portion 52 has a circular shape and has a concave light source housing portion 52b near the center thereof. In addition, in the light source accommodating portion 52b, the light source 6 in which the LED 62 is mounted on the substrate 61 is accommodated so that the ultraviolet ray irradiation direction of the light source 6 is on the side of the flow path 3a. In addition, a plurality of flow paths 52a-1 are provided around the light source accommodating portion 52b.

另外，安裝於基板61的LED 62的數量不限於圖4中圖示的數量。而且，流路52a-1的數量不限定於圖4所圖示的數量。In addition, the number of LEDs 62 mounted on the substrate 61 is not limited to the number illustrated in FIG. 4. In addition, the number of flow paths 52a-1 is not limited to the number illustrated in FIG. 4.

（流體殺菌裝置的主要部分的I-I剖面（B方向）） 圖5是從B方向觀察第一實施方式的流體殺菌裝置的主要部分中的相對於流體流動的方向正交的I-I剖面的剖視圖。(I-I cross section (B direction) of the main part of the fluid sterilization device) FIG. 5 is a cross-sectional view of the main part of the fluid sterilization device according to the first embodiment of the I-I cross section perpendicular to the direction of fluid flow when viewed from the B direction.

即，圖2及圖3中，如果在圖示的B方向上觀察I-I剖面，則如圖5所示，出現第一連結部51及紫外線透光部件7。圖2及圖3中，在I-I剖面的圖示的B方向上觀察的情況下，如圖5所示，第一連結部51為圓狀，其中心附近具有與流路3a連接的圓狀的流路51a-1、及從流路51a-1向第一連結部51的外方呈放射狀延伸的多個流路51a-2。而且，第一連結部51中，在比流路51a-1及流路51a-2更靠近第二連結部52的一側設置著紫外線透光部件7。That is, in FIGS. 2 and 3, if the I-I cross section is viewed in the direction B as shown in the figure, as shown in FIG. 5, the first connecting portion 51 and the ultraviolet light transmitting member 7 appear. In FIGS. 2 and 3, when viewed in the direction B of the diagram of the II cross section, as shown in FIG. The flow path 51a-1, and a plurality of flow paths 51a-2 extending radially from the flow path 51a-1 to the outside of the first connecting portion 51. Furthermore, in the first connecting portion 51, an ultraviolet light transmitting member 7 is provided on the side closer to the second connecting portion 52 than the flow path 51a-1 and the flow path 51a-2.

在將第一連結部51與第二連結部52連結時，圖5所示的各流路51a-2的放射狀的前端部分和位置分別對應的圖4所示的各流路52a-1連接。When the first connecting portion 51 and the second connecting portion 52 are connected, the radial end portions and positions of the respective flow paths 51a-2 shown in FIG. 5 correspond to the respective flow paths 52a-1 shown in FIG. 4 respectively. .

第一實施方式中，例如，流體殺菌裝置1具有：出射紫外線的LED 62安裝於基板61上而成的光源6、及在光源6的發光面側配置紫外線透光部件7而成的光源單元5；以及流路部件3，在光源單元5的發光面側，使從光源6對在流路3a內流動且靠近光源單元5的水進行照射的紫外線在流路3a的壁面反射，光源單元5在包圍光源6的周邊形成多個從光源6的發光面側貫通到相反面側之與流路3a大致同軸的流路51a-1、流路51a-2、流路52a-1、流路52a-2的路徑。In the first embodiment, for example, the fluid sterilization device 1 includes a light source 6 in which an LED 62 that emits ultraviolet rays is mounted on a substrate 61, and a light source unit 5 in which an ultraviolet light transmitting member 7 is arranged on the light-emitting surface side of the light source 6 And the flow path member 3, on the light-emitting surface side of the light source unit 5, the ultraviolet light irradiated from the light source 6 to the water flowing in the flow path 3a and close to the light source unit 5 is reflected on the wall surface of the flow path 3a, and the light source unit 5 is in Surrounding the periphery of the light source 6 are formed a plurality of flow paths 51a-1, flow paths 51a-2, flow paths 52a-1, and flow paths 52a- that penetrate from the light-emitting surface side of the light source 6 to the opposite surface side and are substantially coaxial with the flow path 3a. 2 path.

由此，根據第一實施方式，例如，來自光源6的紫外線在流路3a內反射後再次被照射到流路3a內，可減少向流路3a外漏出的損失，因而能夠有效率地照射到作為殺菌對象的水從而獲得高殺菌效果。而且，根據第一實施方式，例如，光源6發出的熱被水所奪去，且向流體殺菌裝置1外排出，所述水通過形成於包圍光源6的周邊的從光源6的發光面側貫通到相反面側的多個流路，因而能夠使用作為殺菌對象的水有效率地將光源6冷卻而抑制LED 62的溫度上升，從而抑制光源6的LED 62的輸出效率降低。而且，根據第一實施方式，比起其他構成能夠更有效果地進行LED 62的冷卻。而且，根據第一實施方式，也能夠增加光源6中LED 62的安裝數，從而能夠提高流體殺菌裝置1的殺菌效果能力。Thus, according to the first embodiment, for example, the ultraviolet rays from the light source 6 are reflected in the flow path 3a and then irradiated into the flow path 3a again, and the loss of leakage to the outside of the flow path 3a can be reduced, so that it can be irradiated efficiently. The water that is the object of sterilization thus obtains a high sterilization effect. Furthermore, according to the first embodiment, for example, the heat emitted by the light source 6 is deprived of water and discharged to the outside of the fluid sterilization device 1. The water passes through the light-emitting surface side of the light source 6 formed around the periphery of the light source 6 The plurality of flow paths to the opposite surface side enable the light source 6 to be efficiently cooled using water as a sterilization target to suppress the temperature increase of the LED 62, and to suppress the decrease in the output efficiency of the LED 62 of the light source 6. Furthermore, according to the first embodiment, the LED 62 can be cooled more effectively than other configurations. Furthermore, according to the first embodiment, the number of LEDs 62 installed in the light source 6 can also be increased, so that the sterilization effect capability of the fluid sterilization device 1 can be improved.

（第二實施方式） 圖6是表示第二實施方式的流體殺菌裝置的主要部分的剖視圖。(Second Embodiment) Fig. 6 is a cross-sectional view showing a main part of a fluid sterilization device according to a second embodiment.

第二實施方式的流體殺菌裝置1A代替第一實施方式的流體殺菌裝置1中的形成於流路部件3的整個外表面的反射部3b，而在形成流路3a的流路部件3A使用透明的石英管，且代替蓋4，而使用由鋁等形成的筒狀的反射部4A，從流路部件3A的外周覆蓋該流路部件3A。另外，只要反射部4A的內徑大於流路部件3A的外徑，則可為任一大小。此外，只要為由從光源6出射的紫外線能夠由反射部件反射的構成，則可為任一者。The fluid sterilization device 1A of the second embodiment replaces the reflective portion 3b formed on the entire outer surface of the flow path member 3 in the fluid sterilization device 1 of the first embodiment, and uses a transparent flow path member 3A that forms the flow path 3a. A quartz tube is used instead of the cover 4, and a cylindrical reflector 4A formed of aluminum or the like is used, and the flow path member 3A is covered from the outer periphery of the flow path member 3A. In addition, as long as the inner diameter of the reflecting portion 4A is larger than the outer diameter of the flow path member 3A, it may be any size. In addition, as long as it is a structure which can reflect the ultraviolet-ray emitted from the light source 6 by a reflective member, it may be any.

第二實施方式中，例如，流體殺菌裝置1A具有反射部4A，該反射部4A使光源單元5的光源6照射到水的紫外線在流路3a的外周反射。由此，根據第二實施方式，例如，來自光源6的紫外線在反射部4A內反射後留在反射部4A內，從而能夠減少向反射部4A外漏出的損失，因而能夠有效率地照射到作為殺菌對象的水，獲得高的殺菌效果。而且，根據第二實施方式，例如，因在流路部件3A中使用透明石英管，且使用具有反射性的反射部4A從流路部件3A的外周覆蓋該流路部件3A，所以無須對流路部件3A實施反射加工，從而能夠簡化流體殺菌裝置1A的製造工序。In the second embodiment, for example, the fluid sterilization device 1A has a reflecting portion 4A that reflects the ultraviolet rays irradiated to water by the light source 6 of the light source unit 5 on the outer periphery of the flow path 3a. Thus, according to the second embodiment, for example, the ultraviolet rays from the light source 6 are reflected in the reflective portion 4A and remain in the reflective portion 4A, so that the loss of leakage to the outside of the reflective portion 4A can be reduced, and therefore, the ultraviolet rays can be efficiently irradiated to The water to be sterilized has a high sterilizing effect. Furthermore, according to the second embodiment, for example, a transparent quartz tube is used in the flow path member 3A, and the flow path member 3A is covered from the outer periphery of the flow path member 3A with the reflective part 4A having reflectivity, so there is no need for the flow path member 3A. 3A implements reflection processing, so that the manufacturing process of the fluid sterilization device 1A can be simplified.

（第三實施方式） 所述第一實施方式的流體殺菌裝置1及第二實施方式的流體殺菌裝置1A中，在作為殺菌對象的水的流路3a的下游側設置光源單元5。然而，不限於此，也可在流路3a的上游側及下游側，即流路3a的兩端，以相向的方式設置光源單元5-1及光源單元5-2。圖7是表示第三實施方式的流體殺菌裝置的主要部分的剖視圖。(Third Embodiment) In the fluid sterilization device 1 of the first embodiment and the fluid sterilization device 1A of the second embodiment, the light source unit 5 is provided on the downstream side of the flow path 3a of the water to be sterilized. However, it is not limited to this, and the light source unit 5-1 and the light source unit 5-2 may be provided facing each other on the upstream side and the downstream side of the flow path 3a, that is, at both ends of the flow path 3a. Fig. 7 is a cross-sectional view showing a main part of a fluid sterilization device according to a third embodiment.

如圖7所示，第三實施方式的流體殺菌裝置1B具有光源單元5-1、形成流路3a的流路部件3（或流路部件3A）、蓋4（或反射部4A）、及光源單元5-2。As shown in FIG. 7, the fluid sterilization device 1B of the third embodiment has a light source unit 5-1, a flow path member 3 (or a flow path member 3A) forming a flow path 3a, a cover 4 (or a reflection part 4A), and a light source Unit 5-2.

光源單元5-1經由連結部件22而與流路部件23連結，形成使來自流路部件23的水流入到流體殺菌裝置1B內的流路。流路部件3與光源單元5-1連結，在流體殺菌裝置1B內形成作為殺菌對象的水的流路3a。而且，光源單元5-2經由連結部件24而與流路部件25連結，形成使流體殺菌裝置1B內的水向流體殺菌裝置1B外流出的流路。The light source unit 5-1 is connected to the flow path member 23 via the connection member 22 to form a flow path through which water from the flow path member 23 flows into the fluid sterilization device 1B. The flow path member 3 is connected to the light source unit 5-1, and a flow path 3a of water to be sterilized is formed in the fluid sterilization device 1B. Furthermore, the light source unit 5-2 is connected to the flow path member 25 via the connection member 24 to form a flow path through which the water in the fluid sterilization device 1B flows out of the fluid sterilization device 1B.

此處，光源單元5-1及光源單元5-2為與所述第一實施方式或第二實施方式的光源單元5相同的構成。Here, the light source unit 5-1 and the light source unit 5-2 have the same configuration as the light source unit 5 of the first embodiment or the second embodiment.

如圖7所示，從流路部件23流入到流體殺菌裝置1B內的水如圖示的箭頭那樣，在光源單元5-1中，經由流路52a-2、流路52a-1、流路51a-2及流路51a-1而到達流路3a。從流路部件23流入到流體殺菌裝置1B內的水在流路52a-2及流路52a-1中會奪去光源6發出的熱。而且，從光源單元5-1的流路51a-2向流路51a-1流入的水通過流路3a而到達光源單元5-2的流路51a-1之前，被光源單元5-1及光源單元5-2出射的紫外線照射而得到殺菌。As shown in FIG. 7, the water flowing into the fluid sterilization device 1B from the flow path member 23 is as shown by the arrow in the figure. In the light source unit 5-1, it passes through the flow path 52a-2, the flow path 52a-1, and the flow path 51a-2 and the flow path 51a-1 reach the flow path 3a. The water flowing into the fluid sterilization device 1B from the flow path member 23 deprives the heat of the light source 6 in the flow path 52a-2 and the flow path 52a-1. Furthermore, the water flowing from the flow path 51a-2 of the light source unit 5-1 to the flow path 51a-1 passes through the flow path 3a and reaches the flow path 51a-1 of the light source unit 5-2 before being passed by the light source unit 5-1 and the light source. The ultraviolet rays emitted from the unit 5-2 are irradiated and sterilized.

而且，從流路3a到光源單元5-2的流路51a-1的水在光源單元5-2中，經由流路51a-1、流路51a-2及流路52a-1而到達流路52a-2。向光源單元5-2流入的水在流路52a-1及流路52a-2中奪去光源6發出的熱。而且，向光源單元5-2的流路51a-2流入的水經由利用流路部件25形成的流路，而向流體殺菌裝置1B外流出。In addition, the water in the flow path 51a-1 from the flow path 3a to the light source unit 5-2 reaches the flow path through the flow path 51a-1, the flow path 51a-2, and the flow path 52a-1 in the light source unit 5-2. 52a-2. The water flowing into the light source unit 5-2 deprives the heat of the light source 6 in the flow path 52a-1 and the flow path 52a-2. Then, the water flowing into the flow path 51a-2 of the light source unit 5-2 flows out of the fluid sterilization device 1B through the flow path formed by the flow path member 25.

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 fluid sterilization device 1B has light source units 5-1 and 5-2 at both ends of the flow path 3a. Thus, according to the third embodiment, for example, by having two light source units 5-1, 5-2, the sterilization ability of water is further improved compared to the case of having one light source unit 5-1, 5-2.

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 fluid sterilization device 1C, the inner diameter S1 of the flow path 3a formed by the flow path member 3 and the connection portion between the flow path 3a and the flow path 51a-1 of the first connection portion 51C of the light source unit 5C The inner diameter S2 satisfies S1>S2.

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 fluid sterilization device 1C flows through the flow path 3a and reaches the flow path 51a-1 connected to the flow path 3a as shown by the arrow in the figure, the flow path 51a-1 and the flow path The inner diameter S2 of the connection part of the path 3a is smaller than the inner diameter S1 of the flow path 3a, so that water is concentrated near the flow path 51a-1 to improve the ultraviolet radiation efficiency, and convection (vortex) of water is generated near the connection part. The ultraviolet rays emitted from the light source 6 irradiate the convective water for a longer time. Thus, according to the fourth embodiment, it is possible to prevent the water as a sterilization target from passing through the weakly irradiated portion of the ultraviolet rays to reduce the sterilization effect, and the ultraviolet rays are irradiated to the water without any omission, so that the efficiency is improved and the sterilization effect is further improved.

（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 fluid sterilization device 1D, the inner diameter S1 of the flow path 3a formed by the flow path member 3 and the connection between the flow path 3a and the flow path 51a-3 of the first connection portion 51D of the light source unit 5D The inner diameter S3 of the part has a relationship of S1>S3. Furthermore, the flow path 51a-4 extending outward from the flow path 51a-3 is shifted by a predetermined distance in the direction away from the ultraviolet light transmitting member 7.

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 fluid sterilization device 1D flows through the flow path 3a as shown by the arrow and reaches the flow path 51a-3 connected to the flow path 3a, the flow path 51a-3 and the flow path The inner diameter S3 of the connecting portion of 3a is smaller than the inner diameter S1 of the flow path 3a, and the flow path 51a-4 extending outward from the flow path 51a-3 is offset from the ultraviolet light transmitting member 7 by a predetermined distance. Therefore, the water is concentrated in the vicinity of the flow path 51a-3 to increase the efficiency of ultraviolet radiation, and convection (vortex) of water is generated near the connection part and the ultraviolet light transmitting member 7, and the ultraviolet light emitted by the light source 6 irradiates the convective water more. Long time. Thus, according to the fifth embodiment, it is possible to further prevent the sterilization effect of the water as the object of sterilization from being reduced by passing through the weakly irradiated part of the ultraviolet rays, and the ultraviolet rays are irradiated to the water without omission, so that the efficiency is improved and the sterilization effect is further improved. .
