[0002] Conventionally, a fan has been proposed that generates ions to exert effects such as dust removal, deodorization, sterilization, antiviral, and antifungal (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0006] The electric fans described in Patent Documents 1 and 2 above release ions to the outside using airflow, but the amount of ions generated decreases over time. As a result, even using airflow, it is not possible to fill a room or other space with ions. Therefore, even if toxic substances that are harmful to the human body, such as bacteria and viruses, are present in the space, it is difficult to obtain the effect of reliably eliminating, inactivating, or reducing these toxic substances with ions. Consequently, airflow is created while toxic substances remain in the space, and blowing air with an electric fan in this state scatters, agitates, and diffuses toxic substances such as viruses attached to droplets, especially so-called microdroplets and aerosols that are said to have a remarkably long duration of presence in the space, into the indoor space. This poses a problem as it can spread the infection of diseases. Furthermore, the fluid sterilization device described in Patent Document 3 has a problem in that, because it is necessary to irradiate the fluid with a predetermined amount of ultraviolet light or more for sterilization by ultraviolet light, it is extremely difficult to continue irradiating the fluid with ultraviolet light until sterilization is complete, depending on the length and size of the straight pipe.

[0007] This invention was made through the diligent research of the inventors in view of the above-mentioned problems, and aims to provide a means for constructing a channel that can reliably decompose, inactivate, and / or kill toxic targets and reduce their presence with a simple structure.

[0038] An embodiment of a wave amplification device equipped with the wave reflector of the present invention will be described below with reference to the drawings. The wave amplification device has an ultraviolet light emitter (wave generation unit) and a reflector (wave reflector) that generate ultraviolet light as a wave, and is a device that reflects and amplifies ultraviolet light to form a spatial region with a high amount of ultraviolet light. The ultraviolet light emitter is a light source that irradiates ultraviolet light, such as a germicidal lamp, ultraviolet lamp, or ultraviolet LED, which has an appropriate shape such as a straight tube, bulb, or ring, and performs decomposition, inactivation, disinfection, sterilization, and other reductions of toxic targets.

[0039] Such ultraviolet light preferably has a wavelength of 100 to 400 nm, and is particularly desirable to set it around 250 to 270 nm. Of course, the ultraviolet light may also be near-ultraviolet (UV-C), far-ultraviolet (wavelength 10 to 200 nm), or extreme ultraviolet (wavelength 10 to 121 nm), as long as it can at least neutralize the toxic substance. Near-ultraviolet (UV-A, UV-B) with a wavelength exceeding 300 nm may also be used. The reflector has a parabolic surface facing the ultraviolet emitter and reflects the radially irradiated ultraviolet light as parallel light.

[0040] Figure 1 shows a wave amplifier 1 of this embodiment, where (a) is a plan view and (b) is a side cross-sectional view. The wave amplifier 1 has an annular, starter-like ultraviolet light emitter 2, an annular reflector 4, etc., and the ultraviolet light emitter 2 and the reflector 4 are arranged concentrically so as to surround the ultraviolet light emitter 2. In the plan view, the ultraviolet light emitter 2 is hidden by the reflector 4, so its arrangement position is shown by a dotted line in Figure 1(a).

[0041] The reflector 4 has a parabolic surface 6 (reflective portion) on its inner circumferential surface. The parabolic surface 6 extends continuously in a circular manner, is concave, and has a cross-sectional shape that is approximately parabolic. Here, the parabolic shape formed by the cross-section of the parabolic surface 6 is a parabola set with the axis of symmetry perpendicular to the axis of the reflector 4 (the central axis of the ring). The degree of opening of the parabola is not limited here and can be set as appropriate. With respect to such a parabolic surface 6, the ultraviolet light emitter 2 is held by the holding member 3 at a position that overlaps with the focal point of the parabola of the parabolic surface 6. That is, the shapes and positions of the ultraviolet light emitter 2 and the reflector 4 are set so that the geometric center point of the tube cross-section of the ultraviolet light emitter 2 approximately overlaps with the focal point of the parabola formed by the cross-sectional shape of the parabolic surface 6.

[0042] The holding member 3 that holds the ultraviolet light emitter 2 may be provided integrally with the reflector 4, or it may be a separate component from the reflector 4. Furthermore, it is preferable that the holding member 3 is formed of a reflective material that reflects ultraviolet light or a transparent material that transmits ultraviolet light, and that it holds the outer surface of the area where the electrodes (coils) of the ultraviolet light emitter 2 are located. In this way, the holding member 3 is positioned so as to overlap the area where shadows are cast on the ultraviolet light emitter 2, and does not obstruct the radiation of ultraviolet light.

[0043] Here, Figure 2 is a cross-sectional view showing the ultraviolet emitter 2 and the reflector 4. The ultraviolet emitter 2 has a reflective surface 8 on part of its inner surface (the surface inside the tube) or outer surface (the surface outside the tube). This is so that the ultraviolet emitter 2 can radiate ultraviolet light radially in almost all directions when viewed in cross-section, and so that ultraviolet light does not leak to the outside of the reflector 4. The reflective surface 8 is the part of the ultraviolet emitter 2 that does not face the parabolic surface 6, such as the part facing the radially inward side. Therefore, the ultraviolet emitter 2 radiates ultraviolet light toward the parabolic surface 6 across its entire surface.

[0044] The parabolic surface 6 and reflective surface 8 described above can be made of an ultraviolet reflective material. The ultraviolet reflective material preferably has a diffuse transmittance of 1% / 1mm or more and 20% / 1mm or less, and a total reflectance in the ultraviolet region of 60% / 1mm or more and 99.9% / 1mm or less, with the sum of the diffuse transmittance and the total reflectance in the ultraviolet region being 90% / 1mm or more. Such an ultraviolet reflective material may include at least one of the following: silver, aluminum, polytetrafluoroethylene (PTFE), silicon resin, quartz glass containing bubbles of 0.05 μm to 10 μm, partially crystallized quartz glass containing crystal grains of 0.05 μm to 10 μm, alumina sintered body with crystal grains of 0.05 μm to 10 μm, and mullite sintered body with crystal grains of 0.05 μm to 10 μm. Furthermore, the ultraviolet reflective surfaces of the parabolic surface 6 and the reflective surface 8 may be formed by processes such as attaching aluminum foil, anodizing the aluminum surface, vacuum deposition of aluminum, vacuum deposition of silver, or application of a two-component thermosetting ink that forms an ultraviolet reflective film. Alternatively, the ultraviolet reflective surfaces may be formed by combining multiple processes from the above-mentioned processes, for example, by performing anodizing and vacuum deposition of aluminum.

[0045] Furthermore, when using silver or aluminum for the parabolic surface 6, a UV-transmitting film that functions as a coating may be applied to the surface to prevent oxidation. In this case, the transparent film can be made of acrylic resin, quartz glass, PTFE, etc. Methods for forming thin films with quartz glass or PTFE include vapor deposition and sputtering.

[0046] Furthermore, a reflective layer can be formed on the parabolic surface 6 and the reflective surface 8. The reflective layer is configured to be transparent to visible light and infrared rays, and reflective to ultraviolet rays. Such a reflective layer can be formed, for example, by a dielectric multilayer film obtained by depositing a dielectric material in multiple layers on the parabolic surface 6 and the reflective surface 8. Alternatively, a thin plate on which a dielectric multilayer film layer is formed may be attached to the parabolic surface 6 and the reflective surface 8. In this case, the thin plate is made of a material that is transparent to visible light and infrared rays.

[0047] A dielectric multilayer film is a film that can be constructed by alternately stacking dielectric thin films of high refractive index materials and dielectric thin films of low refractive index materials. Examples of high refractive index materials include titanium dioxide (TiO2), tantalum pentoxide (Ta2O5), aluminum oxide (AL2O3), zirconium oxide (ZrO2), and zinc sulfide (ZnS). Examples of low refractive index materials include silicon dioxide (SiO2), zinc peroxide (ZnO2), and magnesium fluoride (MgF2).

[0048] The thickness of the reflective layer can be set as appropriate, but when formed by a multilayer film, the thickness of each layer can be set to an integer multiple of 1 / 4 of the wavelength of the ultraviolet light to be reflected (an odd or even multiple of 1 / 4 of the wavelength of ultraviolet light). Specifically, if the wavelength of the ultraviolet light to be reflected is set to 253.7 nm, the thickness of each layer can be set to 63.4 nm (i.e., 1x 1 / 4 of the wavelength), 126.8 nm (i.e., 2x 1 / 4 of the wavelength), 190.3 nm (3x 1 / 4 of the wavelength), etc. Of course, when the reflective layer is formed by a multilayer film, the film thickness per layer may be a so-called thick film of several tens of micrometers, a so-called thin film of several micrometers, or a so-called ultrathin film of a few nanometers or less.

[0049] Figure 3 shows the round-trip path of ultraviolet light. The ultraviolet light emitted radially from the ultraviolet emitter 2 is reflected by the parabolic surface 6, becoming parallel rays parallel to the axis of symmetry of the parabola formed by the cross-section of the parabolic surface 6. That is, the ultraviolet light becomes parallel rays parallel to the radial direction of the reflector 4 and travels back and forth within the space surrounded by the parabolic surface 6. Specifically, on the left side of Figure 3, the ultraviolet light emitted from a portion 2L of the ultraviolet emitter 2 is reflected by the surface 6L of the opposing parabolic surface 6, becoming parallel light that travels along the radial direction. The parallel ultraviolet light then travels to the surface 6R, which is symmetrical to surface 6L. The ultraviolet light is then reflected by surface 6R and focused onto a portion 2R of the ultraviolet emitter 2 that is opposite surface 6R.

[0050] Ultraviolet light focused on a portion 2R is reflected by the reflective surface 8 inside that portion 2R. Then, similar to the ultraviolet light emitted from portion 2R, it is reflected by the surface 6R of the opposing parabolic surface 6, becoming parallel light that travels radially. The parallel ultraviolet light then travels toward surface 6L, and is reflected by surface 6L, focusing onto a portion 2L of the ultraviolet emitter 2. In this way, the ultraviolet light travels back and forth within a predetermined region, such as between portions 2R and 2L, while being reflected by the parabolic surface 6. In other words, the parabolic surface 6 functions to reflect ultraviolet light emitted from the ultraviolet light emitter 2 in a direction approximately parallel to the axis of symmetry of the parabola of the parabolic surface, thereby creating an ultraviolet light reciprocating region (wave reciprocating region) that causes the ultraviolet light to travel back and forth.

[0051] As described above, according to the wave amplification device 1 of the present invention, ultraviolet light emitted from the ultraviolet light emitter 2 is reflected by the parabolic surface 6 and the reflective surface 8, becoming parallel light parallel to the direction perpendicular to the axis of the reflector 4, and can be made to reciprocate within a predetermined area. That is, since the reflector 4 has a shape that surrounds the ultraviolet light emitter 2, the ultraviolet light emitted from the ultraviolet light emitter 2 can emit a high dose of ultraviolet light in substantially the entire space surrounded by the reflector 4, and toxic targets such as bacteria, viruses, and molds present in the space can be reliably decomposed, inactivated and / or killed, and reduced.

[0052] Furthermore, since the reflector 4 has a parabolic surface with a substantially parabolic cross-section, if the ultraviolet emitter 2 is positioned to align with the focal point of the parabola, almost all of the ultraviolet light emitted from the ultraviolet emitter 2 can be reflected as parallel rays, creating an ultraviolet reciprocating region. As a result, a high-density ultraviolet space is formed in the space surrounded by the reflector 4. Therefore, even by simply placing the wave amplifier 1 in the flow path of a fluid such as air, a flow path that reliably reduces toxic substances can be formed.

[0053] Furthermore, the reflector 4 may have a parabolic surface 7 (reflective portion) (see Figure 4) with a cross-sectional shape other than a substantially parabolic cross-section, as long as it can reflect ultraviolet light emitted from the ultraviolet light emitter. For example, as shown in Figure 4(a), the parabolic surface 7 may have a cross-sectional shape comprising a main surface 7a perpendicular to the radial direction of the ultraviolet light emitter 2 and inclined surfaces 7b at both ends of the main surface 7a that are inclined at an obtuse or acute angle with respect to the main surface 7a. Also, as shown in Figure 4(b), the parabolic surface 7 may be formed with a substantially U-shaped cross-section, and as long as the parabolic surfaces 7 are arranged so that the openings of the U-shape face each other, the parabolic surfaces 7 do not have to extend continuously along the inner circumferential surface of the reflector 4, but may be arranged intermittently. Furthermore, the parabolic surface 7 may have a cross-sectional shape that is an arc shape as shown in Figure 4(c), or it may have an elliptical arc shape as shown in Figure 4(d). Also, the cross-sectional shape of the parabolic surface 7 may be other than the shapes described above, and can be set to any shape as appropriate, such as a curved surface, a convex surface, or a concave surface. Although the reflective surface of the ultraviolet emitter 2 for each of the parabolic surfaces 7 described above is on the radially inner side, it is of course not limited to this, and a configuration without a reflective surface may be used as long as it can create a high-dose ultraviolet region. For example, the ultraviolet emitter 2 may have a reflective surface 8 on its radially outer circumferential surface and emit ultraviolet light from the radially inner side.

[0054] Furthermore, the reflector 4 can have an appropriately set shape in plan view, as long as it has a substantially parabolic surface (reflective part) at least in the area facing the ultraviolet light emitter. Figure 5 shows an example of the plan view shape of the reflector 4, and the reflector 4 may have a shape other than a perfect circular annular shape in plan view. For example, there may be an oval annular shape as shown in Figure 5(a) or an elliptical annular shape as shown in Figure 5(b). In addition to the rectangular shape shown in Figure 5(c) and the pentagonal shape shown in Figure 5(d), there may also be polygonal annular shapes such as triangular or hexagonal shapes. Furthermore, it may also be an annular shape with a part open, such as the substantially semicircular shape shown in Figure 5(e) or the substantially U-shaped shape in plan view shown in Figure 5(f). Even with such a reflector, ultraviolet rays can be reflected and travel back and forth in the area where the parabolic surfaces face each other across the ultraviolet light emitter, increasing the dose of ultraviolet rays emitted from the ultraviolet light emitter. Of course, the reflectors are not limited to those that extend continuously; it goes without saying that a pair (or more pairs) of reflectors facing each other with the ultraviolet reflector 2 in between may also be provided.

[0055] Furthermore, in addition to the shapes described above, the reflector may also be a substantially cylindrical shape having a concave parabolic surface 12 forming a substantially parabolic shape on its outer surface, as shown in Figure 6, or a cylindrical reflector 10 with a body that forms a parabolic surface 12. In this case, the ultraviolet light emitter 16 can be set to an appropriate shape, such as a point light source such as an ultraviolet LED disposed on the outside of the reflector 10, or an arc shape, a curved shape, a line segment shape, etc. Alternatively, multiple ultraviolet light emitters 16 may be arranged at intervals along the circumferential direction of the reflector 10 to form a group of emitters. If the reflector 10 is substantially circular in plan view, multiple ultraviolet light emitters 16 are arranged in a circular shape along the circumferential direction of the reflector 10. Of course, for a reflector 4 having a parabolic surface 6 on its inner circumference, multiple ultraviolet light emitters 16 may be arranged along the circumferential direction on the inner circumference of the reflector 4.

[0056] In a wave amplification device comprising a reflector 10 and an ultraviolet emitter 16, ultraviolet light emitted from the ultraviolet emitter 16 is reflected by the parabolic surface 12 so as parallel rays directed radially outward. Therefore, by placing an ultraviolet-reflective reflector 14 opposite the parabolic surface 12 with the ultraviolet emitter 16 in between, ultraviolet light can be made to travel back and forth between the parabolic surface 12 and the reflector 14.

[0057] The reflectors 14 only need to reflect ultraviolet light reflected by the reflector 10 towards the parabolic surface 12 so that it does not leak out to the outside, and their shape and number can be set as appropriate. For example, the reflectors 14 may have an annular shape and surround the reflector 10 and the ultraviolet light emitter 16, or multiple reflectors may be arranged around the reflector 10 depending on the number of ultraviolet light emitters 16 installed.

[0058] Next, a toxic substance elimination device 20 using a wave amplification device 1 will be described. Figure 7 shows the toxic substance elimination device 20, where (a) is an external view and (b) is a cross-sectional view. The toxic substance elimination device 20 has a substantially cylindrical housing 22 as shown in Figure 7(a), and the wave amplification device 1, a flow generation unit 30, an ultraviolet leakage suppressor 32, etc. are arranged inside the housing 22.

[0059] The housing portion 22 is cylindrical with at least one end being an open end, and has a fluid passage port 24 formed by cutting out the circumferential surface of the other end to create multiple slit-shaped holes. The toxicity mitigation device 20 draws in fluid from either the open end or the fluid passage port 24, and discharges fluid from the other end. Furthermore, the term "fluid" encompasses gases, liquids, and powders, while "toxic objects" include pathogenic microorganisms such as bacteria and viruses, as well as pollen and harmful molecules such as formaldehyde, sulfur dioxide, and nitrite, which are at least toxic to the human body and move along with the fluid.

[0060] The fluid generation unit 30 is located near the fluid passage opening 24 inside the housing unit 22. The fluid generation unit 30 has a fan structure for causing the fluid to flow axially within the housing unit 22. Specifically, the fan structure of the fluid generation means 30 has a propeller 34 with multiple blades arranged around a rotation axis parallel to the axis of the housing unit 22, a motor (drive source) for driving the propeller, etc.

[0061] Furthermore, any fan structure can be applied to the flow generation section 30 as long as it is capable of flowing fluid. For example, axial flow fans (propeller fans), mixed flow fans, centrifugal fans (multi-blade fans, sirocco fans, radial fans, plate fans, turbo fans, limit load fans, airfoil fans, etc.), centrifugal axial flow fans, vortex flow fans, cross-flow fans, etc. can be applied. Furthermore, multiple flow generation units 30 may be provided; for example, multiple units can be arranged axially so as to sandwich the wave amplification device 1.

[0062] The ultraviolet leakage suppressor 32 is positioned to cover the open end and has a structure that prevents ultraviolet rays from being emitted outside the device while not obstructing the fluid flow along the channel. For example, the ultraviolet leakage suppressor 32 has a plurality of shielding regions 32a to 32c arranged in the axial direction, which can prevent people from looking into the interior from the open end. For example, the shielding regions 32a to 32c are composed of a plurality of annular, radially inclined light-shielding surfaces arranged concentrically. Here, in at least adjacent shielding regions 32a to 32c, the inclination angles of the light-shielding surfaces are set such that the interior of the toxicity target reduction device 20 cannot be directly seen, for example. The light-shielding surfaces arranged radially are adjacent to each other with gaps between them, and these gaps prevent obstruction of the flow. Of course, the light-shielding sections are arranged axially and have a curved shape so that the inside of the device cannot be directly seen. In addition, the spacing and angles of the light-shielding sections can be set as appropriate so that they overlap when viewed from above. Furthermore, the light-shielding sections are not limited to annular shapes, but may also be radial or linear in shape.

[0063] Furthermore, as a means of ensuring safety by preventing objects from entering the interior from the opening or people from peeking inside, a human detection sensor or an object detection sensor may be provided to turn off the ultraviolet light emitter or stop the operation of the fan (flow generation unit 30) when a person or object is detected.

[0064] According to the above-described toxic substance reduction device 20, for example, air taken in through the fluid passage port 24 by driving the fluid generation unit 30 passes through the wave amplification device 1 and is discharged from the opening end, while toxic substances in the air can be reduced. That is, air flowing into the device from the fluid passage port 24 passes through a region with a high amount of ultraviolet light created by the wave amplification device 1 (a region in the inner space of the wave amplification device 1), passes through the opening end and is discharged to the outside. Toxic substances in the air are reduced as they pass through the region with a high amount of ultraviolet light.

[0065] Thus, by incorporating the wave amplifier 1, the toxic substance elimination device 20 can take in an external fluid and radiate a high dose of ultraviolet light onto toxic substances in the fluid, thereby eliminating the toxic substances.

[0066] In addition, although the above-mentioned toxicity reduction device 20 has the wave amplifier 1 installed in one location, it goes without saying that multiple units may be installed. For example, multiple wave amplifiers 1 may be installed along the axial direction, and in this case, the wave amplifiers 1 may be placed adjacent to each other as shown in Figure 8(a). Alternatively, the wave amplifiers 1 may be spaced apart as shown in Figure 8(b), in which case it is possible to place a wave generating unit 30 or the like between the wave amplifiers 1.

[0067] Alternatively, the reflectors may be arranged radially. That is, as shown in Figure 9, a columnar reflector 10 may be arranged radially inside the annular reflector 4. In this case, the reflector and the ultraviolet emitter may be paired. That is, an ultraviolet emitter 2 may be provided for the reflector 4, and an ultraviolet emitter 16 may be provided for the reflector 10. Of course, it goes without saying that the number and shape of reflectors arranged along the axial and / or radial directions are not limited to these.

[0068] Furthermore, the wave amplification device 1 may be equipped with an antifouling member to protect the surface of the ultraviolet light emitter and the parabolic surface, and to prevent foreign matter and dirt such as dust and grime from adhering to it. For example, Figure 10 is a cross-sectional view showing a toxic substance reduction device 20 having an antifouling member 40, the antifouling member 40 having a substantially cylindrical shape made of an ultraviolet light transmitting material, and is disposed in the space inside the reflector 4, radially inward from the ultraviolet light emitter 2. The antifouling member 40 is set so that its axial length is substantially equivalent to the axial length of the reflector 4. It is also desirable to provide a sealing structure between the antifouling member 40 and the reflector 4, such as by interposing a sealing member, to prevent foreign matter from entering between the antifouling member 40 and the reflector 4 and to prevent foreign matter and dirt from adhering to the ultraviolet light emitter 2. Furthermore, UV-transmitting materials may include glass, quartz (SiO2), sapphire (Al2O3), amorphous fluoropolymer resins such as PTFE, and acrylic resins.

[0069] By installing the anti-fouling member 40, it is possible to prevent a decrease in ultraviolet radiation dose due to the adhesion of foreign matter, dirt, etc., to the surface of the reflector 4. Furthermore, if the anti-fouling member 40 is made removable, it becomes easier to clean the surface of the anti-fouling member 40 when it becomes dirty, or to replace the anti-fouling member 40 itself, thereby improving maintainability. In addition, it becomes possible to minimize pressure loss by not obstructing the flow of fluid passing through the toxic substance reduction device 20.

[0070] Furthermore, the number and shape of the anti-fouling members 40 can be set as appropriate. For example, when two sets of reflectors and ultraviolet emitters are arranged in the axial direction (as shown in Figure 8(a)), an anti-fouling member 40 may be placed for each reflector, or a long anti-fouling member extending across the two reflectors may be placed.

[0071] Furthermore, the ultraviolet light emitter may be either an electrode type with electrodes or filaments, or an electrodeless type that does not use electrodes or filaments. However, the electrodeless type has more coils that generate high-frequency magnetic fields compared to the electrode type, so shadows are more likely to form when emitting ultraviolet light.

[0072] Figure 11 shows an example of an electrodeless type ultraviolet light emitter 42. The electrodeless type ultraviolet light emitter 42 has a configuration in which there are two (or more) coil sections 44 along the circumferential direction. However, ultraviolet light is not emitted from the coil sections 44, resulting in the generation of a wide shadow. Therefore, in order to suppress the effects of shadow generation, it is desirable to install multiple ultraviolet light emitters. By arranging multiple ultraviolet light emitters 42, the range over which ultraviolet light is emitted is widened, and the orientation of each ultraviolet light emitter 42 is set so that the shadows cast by each ultraviolet light emitter 42 do not overlap along the direction of fluid flow.

[0073] For example, as shown in Figure 8, when the ultraviolet emitters 42 are arranged in two stages in the axial direction, the orientation and arrangement phase of each ultraviolet emitter 42 are set such that the coil portions 44 of the first stage ultraviolet emitter 42 are aligned horizontally, and the orientation of the second stage ultraviolet emitter 42 is set such that the coil portions 44 are aligned vertically, so that the shadows generated by each ultraviolet emitter 42 do not overlap in the axial view. In this way, when the fluid passes through the wave amplifier 1, it can pass through the region where ultraviolet light is emitted, and toxic substances in the fluid can be reliably reduced and eliminated.

[0074] Furthermore, the reflector and the ultraviolet emitter may be integrated. For example, a starter-like, annular ultraviolet lamp may be provided with a reflective surface having ultraviolet reflectivity on the inner or outer surface of the tube of the ultraviolet lamp, so that the entire ultraviolet lamp functions as a wave amplifier. Figure 13 shows an example of an annular ultraviolet lamp type wave amplifier 50, which consists of an annular ultraviolet lamp 52 and a reflective surface 54.

[0075] The reflective surface 54 is formed in a cross-section parallel to the axis of the ultraviolet lamp 52, extending across the inner, radially outer, and axial ends of the circumferential surface of the ultraviolet lamp 52. Therefore, the ultraviolet lamp 52 does not have a reflective surface 54 on its radially inner circumferential surface, which serves as a path for ultraviolet light to pass to the outside. Furthermore, ultraviolet light directed in directions other than radially inward is reflected by the reflective surface 54, resulting in it being radiated outward from the radially inward circumferential surface.

[0076] With this wave amplification device 50, the ultraviolet light emitted by the ultraviolet lamp 52 is emitted radially inward from the side that does not form a reflective surface 54, i.e., from the inner circumferential surface side of the ultraviolet lamp 52. Furthermore, the ultraviolet light emitted from the ultraviolet lamp 52 can travel through the space surrounded by the inner circumferential surface of the ultraviolet lamp 52, enter the ultraviolet lamp 52 at a location opposite the axis, and be reflected again by the reflective surface 54 located at that location. Therefore, the ultraviolet light emitted from the ultraviolet lamp 52 can travel back and forth multiple times within the space surrounded by the ultraviolet lamp 52, resulting in the formation of a high-density ultraviolet region.

[0077] Multiple wave amplifiers 50 may be installed; for example, as shown in Figure 14, multiple amplifiers may be arranged along the direction perpendicular to the radial direction (axial direction) of the ultraviolet lamps 52. In this way, the high-density ultraviolet region can be expanded along the axial direction. Of course, the number of ultraviolet lamps 52 is not limited to the two shown in Figure 14, but may be three or more.

[0078] Furthermore, antifouling members 40 can also be provided for such wave amplification devices 50. For example, when three ultraviolet lamps 52 are arranged as shown in Figure 15, cylindrical antifouling members 40 can be inserted and provided to span the spaces surrounded by each ultraviolet lamp 52. Moreover, by setting the outer diameter of the antifouling member 40 so that its outer surface is close to the tubes of the ultraviolet lamps 52, it is possible to prevent the surface of the ultraviolet lamps 52 from becoming contaminated by foreign matter passing through the spaces surrounded by the ultraviolet lamps 52.

[0079] Furthermore, as long as the purpose is to reflect and oscillate ultraviolet light within a predetermined area, the wave amplification device may be configured simply with a general annular-shaped ultraviolet lamp 60 and a cylindrical reflector 70 surrounding it, as shown in Figure 16(a). In this case, the inner circumferential surface 72 of the reflector 70 can be set to an appropriate shape as long as it has at least ultraviolet reflectivity, and may, for example, have a shape corresponding to the parabolic surface 6 described above. Also, as shown in Figure 16(b), the number of ultraviolet lamps 60 arranged inside the reflector 70 can be set as appropriate, such as arranging three ultraviolet lamps 60 for one reflector 70.

[0080] Furthermore, the ultraviolet lamp 60 may also be provided with a reflective surface 62 that reflects ultraviolet light along its circumferential surface. For example, as shown in Figure 17(a) in a plan view, the reflective surface 62 may be provided over the entire outer circumference, as shown in Figure 17(b), or as shown in Figure 17(c), it may be provided over half of the outer circumference. Of course, the reflective surface 62 may extend over half of the inner circumference, or it may be formed intermittently along the circumferential direction of the outer circumference and / or inner circumference, and can be set to any appropriate shape and range.

[0081] Furthermore, although the ultraviolet light emitter was described as an annular shape in the above-described embodiment, the shape of the ultraviolet light emitter can be appropriately set according to the shape of the reflector. For example, in a plan view, if the reflector 4 shown in Figure 18(a) is rectangular, a rectangular ultraviolet light emitter 2 may be provided, or multiple linear ultraviolet light emitters 2 may be provided and arranged in a row along the circumferential direction of the opposing reflectors 4, as shown in Figure 18(b). Alternatively, multiple point light source-shaped ultraviolet light emitters 2 may be provided and arranged in a row along the circumferential direction of the reflector 4, as shown in Figure 18(c).

[0082] Furthermore, although the above-described toxic substance reduction device 20 has the flow generation unit 30 and the wave amplification device 1 adjacent to each other, it is of course not limited to this arrangement, and they may be arranged spaced apart along the direction of fluid flow. For example, they may be arranged in a conduit that guides the fluid flow within the toxic substance reduction device 20. In that case, as shown in Figure 19, the conduit 80 is arranged to pass through the wave amplification device 1. The flow generation unit 30 is located at one end of the conduit 80. The wave amplification device 1 is located at the other end of the conduit 80, etc. Therefore, the fluid moving within the conduit 80 flows downstream due to the flow generated by the flow generation unit 30. Then, by passing through the high-density ultraviolet region generated by the wave amplification device 1, toxic substances present within the conduit 80 can be reduced.

[0083] Furthermore, the conduit 80 is formed of an ultraviolet-transmitting material at the location where the wave amplifier 1 is installed. It goes without saying that the conduit 80 may also be configured to function as the anti-fouling member for the wave amplifier 1. In addition, if the conduit 80 is installed so that its interior can be seen from the outside, it is desirable to install the ultraviolet leakage suppressor 32, but if it is installed so that its interior cannot be seen, the configuration may be made without the ultraviolet leakage suppressor 32.

[0084] Furthermore, although ultraviolet light was used as an example in the embodiments described above, the invention is not limited to this, and waves can also be sound waves, radio waves, microwaves, infrared rays, visible light, etc. The reflector should be a parabolic reflective material depending on the wave. The reflective material may be, for example, a conductive material (aluminum, copper, plating, etc.) or a material that combines a conductive material and a resin material in layers. For example, when using visible light as a wave, the wave amplification device 1 can function as a device that amplifies the amount of visible light within a predetermined region to increase the amount of light emitted.

[0085] Furthermore, the wave amplification device of the present invention can be used by mounting it on, embedding it in, incorporating it into, or combining it with various devices and equipment. Such devices and equipment can be used in any device in which fluid can flow inside, such as air conditioners, electric fans, circulators, air purifiers, humidifiers, dehumidifiers, ventilation fans, vacuum cleaners, circulation pumps, mist showers (sprayers), exhaust systems, plants, septic tanks, piping, connecting members for connecting pipes, etc. The number and placement of the wave amplification devices can be set as appropriate. For example, multiple wave amplification devices may be placed in the middle of a fluid flow path.

[0086] Furthermore, devices equipped with wave amplification devices are not limited to those having a mechanism for fluid flow; they may also include devices configured so that at least the suction and discharge parts communicate with the outside in order to allow fluid to pass through. Examples of such devices include vehicle roofs, seat backs, seat headrests, plywood panels, tables, desks, chairs, walls, ceilings, elevators, etc. In particular, when using ultraviolet light emitters to reduce or eliminate toxic substances, they can be embedded and used in devices installed in spaces where people gather or where people tend to congregate.
