Description

Ultraviolet sterilizer

The present invention relates to an ultraviolet sterilizing device that can automatically sterilize an entire object.

Awareness of the crisis of infectious diseases is on the rise, and the need for ordinary people to sterilize their own hands or hands in order to protect themselves from infection is also increased. Further, as a sterilizing device that meets such a demand, a portable sterilizing device as disclosed in Patent Document 1 or Patent Document 2 is proposed. In such devices, ultraviolet rays having a sterilizing action, which are emitted from an ultraviolet lamp such as a xenon flash lamp, are irradiated onto the object to be sterilized and sterilized.

On the other hand, a deep ultraviolet light emitting diode (DUV-LED) is known as a light source having ultraviolet light having a bactericidal action, and the DUV-LED is compared with an ultraviolet light lamp because the light output is weak, so it is not known. There is a portable ultraviolet sterilizer that uses this element.

In addition, it is known that a plurality of ultraviolet light-emitting diodes can be arranged to be modularized, and a purple light having a high output of ultraviolet light is emitted. The external beam irradiation device (see Patent Document 3, FIG. 3) is limited in the case where ultraviolet irradiation is performed using the ultraviolet irradiation device.

Patent Document 2 Japanese Patent Laid-Open Publication No. 2005-323654

In the portable sterilizing device described in Patent Documents 1 and 2, an ultraviolet ray having a relatively high intensity of ultraviolet rays such as a xenon flash lamp is used as the ultraviolet ray source. Therefore, the ultraviolet ray irradiation region is relatively wide and can be short. Time will benefit from the sterilization of the surface of the sterilized object. On the contrary, there is a large amount of power consumption, and there is a problem that the lamp is damaged due to rushing, and the life is also short. On the other hand, although the ultraviolet light emitting diode (DUV-LED) has the advantages of less power consumption and higher durability, it is compared with the ultraviolet light as described above because the light output is weak, so it is not known. There is a portable ultraviolet sterilizing device using this element. Further, since the directivity of the ultraviolet light emitted by the DUV-LED is generally high, the irradiation area of the ultraviolet light is narrowed. because On the other hand, in the portable sterilizing apparatus of Patent Documents 1 and 2, it is difficult to obtain a sufficient sterilizing effect only when the light source is replaced with a DUV-LED.

According to the invention described in Patent Document 3, it is possible to irradiate parallel light having an increased intensity. However, when the article is actually sterilized by using the ultraviolet irradiation device of the present invention, it is necessary to change the irradiation position of the object one by one.

Therefore, an object of the present invention is to provide an ultraviolet ray sterilizing apparatus using a DUV-LED as an ultraviolet light source, which can also be used as a carrier, and can improve the operability of sterilization of articles.

An ultraviolet ray sterilizing apparatus according to the present invention is characterized by comprising: an ultraviolet ray sterilizing unit having a frame body having an opening; and an ultraviolet ray permeable window having ultraviolet ray permeable and having an inner side surface and a side opposite to the inner side surface The outer side surface is disposed such that the inner side surface is disposed inside the frame body so as to close the opening of the frame body; the light source has one or more ultraviolet light emitting diodes, and the ultraviolet light is emitted as a band-shaped light beam; and the scanning mechanism is The ultraviolet light from the light source is irradiated with ultraviolet rays from the light source when the ultraviolet light from the light source is incident on the ultraviolet light transmission window in a direction intersecting the width direction of the strip light beam, so that the ultraviolet light from the light source can be irradiated from the inside of the housing body over the ultraviolet ray. Ultraviolet rays are irradiated onto the entire surface of the inner side surface of the window to sterilize the object to be sterilized disposed to face the outer surface of the ultraviolet ray transmitting window.

In the present application, the "width" of the band beam "Direction" means the lengthwise direction on the cross section perpendicular to the propagation direction of the strip beam.

In the present invention, the light source is preferably a deep ultraviolet ray having a wavelength of 200 nm to 300 nm, particularly preferably 220 nm to 280 nm.

The ultraviolet ray sterilizing unit of the ultraviolet ray sterilizing apparatus of the present invention is preferably any of the following aspects (1) and (2).

In the aspect of (1) (hereinafter also referred to as "first ultraviolet ray sterilizing unit"), the scanning mechanism includes a mirror disposed inside the housing and a driving device for changing the angle of the mirror, and the light source is configured to The strip beam is emitted toward the mirror, and the mirror is arranged to reflect the strip beam toward the ultraviolet ray transmitting window, and the angle of the mirror is changed by the driving device, and the ultraviolet ray reflected by the mirror is incident on the ultraviolet ray transmitting window toward the strip. The directions in which the width directions of the beams cross are staggered.

In the aspect of (2) (hereinafter also referred to as "second ultraviolet ray sterilizing unit"), the light source is disposed in the casing so that the strip beam is emitted toward the ultraviolet ray transmitting window, and the scanning mechanism has a moving mechanism. The light source is slidably moved in such a manner as to change the incident position of the strip beam to the ultraviolet ray transmission window.

The second ultraviolet ray sterilizing unit has a feature that the light source is slidably moved along a curved surface which is formed by a cylindrical surface, an elliptical cylinder surface or a parabolic cylindrical surface and which is concavely curved as viewed from the side of the ultraviolet ray transmission window. The sterilizing unit (hereinafter also referred to as "the third ultraviolet ray irradiation unit") can illuminate the ultraviolet ray from the lower side of the object to be sterilized or the lower side of the object to be sterilized.

Among these aspects, a particularly preferable aspect is that the scanning mechanism is obtained by shifting the ultraviolet light from the light source incident on the ultraviolet ray transmitting window toward the width direction of the strip beam. When the ultraviolet light of the light source is irradiated from the inside of the casing, the incident angle of the ultraviolet rays to the inner side surface of the ultraviolet ray transmitting window is changed, and ultraviolet rays can be irradiated to the ultraviolet ray irradiation region of the sterilizing target at two or more different incident angles.

In addition, the ultraviolet ray sterilizing apparatus of the present invention includes a configuration in which two or more ultraviolet ray sterilizing units are connected to each sterilizing unit by a bendable connecting member (hereinafter also referred to as "connected type"). In the ultraviolet ray sterilizing apparatus of the present invention, the ultraviolet ray sterilizing apparatus of the present invention can be irradiated with ultraviolet rays from both the upper and lower (or front and rear) directions of the sterilizing object, for example, by arranging the two ultraviolet ray sterilizing units so as to face each other. In the case where the three-dimensional sterilization target is sterilized, it is possible to sterilize more reliably by one irradiation. In particular, when the third ultraviolet irradiation unit is disposed to face each other, since ultraviolet rays can be irradiated from the right and left oblique directions and the right and left oblique directions, even in the case where the stereoscopic sterilization target is sterilized, One shot is more sterilized.

In the connection type ultraviolet ray sterilizing device, the cymbal for attaching the connecting member is provided in each of the ultraviolet ray sterilizing units, and the connecting member can be detachably attached, and the connecting member can be detachably connected to the connecting member. Each of the ultraviolet ray sterilizing units is used as an individual ultraviolet ray sterilizing device (non-connecting type) of the present invention.

Further, in the ultraviolet ray sterilizing apparatus of the present invention, preferably, the light source (hereinafter also referred to as "concentrating module light source") has a rod-shaped light source that emits deep ultraviolet rays, and a rod-shaped light source that will be emitted from the rod-shaped light source a concentrating device that condenses the emitted deep ultraviolet rays, wherein the rod-shaped light source is a rod-shaped light source having a cylindrical or polygonal columnar body and a plurality of deep ultraviolet light emitting diodes, and the plurality of deep ultraviolet rays The light-emitting diode is disposed on the side surface of the cylindrical or polygonal columnar substrate such that the optical axis of each of the deep ultraviolet light-emitting diodes passes through the central axis of the cylindrical or polygonal columnar substrate. The central axis radiates deep ultraviolet rays radially, the concentrating device has a long elliptical mirror, and the rod-shaped light source is disposed on a focal axis of the long elliptical mirror, and the long elliptical mirror has a long elliptical mirror for The ultraviolet light emission opening that is emitted by the ultraviolet light collected on the condensing axis has a collimating optical system that improves the directivity of the condensed ultraviolet ray in the ultraviolet light emission opening.

Further, in the ultraviolet ray sterilizing apparatus of the present invention, it is preferable to further provide an ultraviolet opaque cover for preventing ultraviolet rays emitted from the light source from leaking to the outside, and to arrange the sterilizing object on the outer surface of the ultraviolet ray transmitting window and the outer cover. Space between.

According to the ultraviolet ray sterilizing apparatus of the present invention, the ultraviolet ray irradiated from the light source is irradiated onto the entire surface of the inner surface of the ultraviolet ray transmitting window by the scanning means, whereby the object to be sterilized can be automatically sterilized. In particular, according to the scanning mechanism, ultraviolet rays from the light source are incident on the ultraviolet light through one side. When the position of the window is shifted in the direction intersecting the width direction of the strip beam, and the ultraviolet light from the light source is irradiated from the inside of the housing, the incident angle of the ultraviolet ray to the inner side surface of the ultraviolet ray transmitting window is changed, and the object can be sterilized. In the ultraviolet ray irradiation region, the ultraviolet ray is irradiated at two or more different incident angles, and scanning is performed while irradiating the ultraviolet ray at various angles from the lower side of the sterilizing target (the ultraviolet ray transmitting window side) (the irradiation region is moved). The sterilized object having irregularities on the surface is reliably sterilized.

By using the ultraviolet ray sterilizing apparatus of the present invention as described above, for example, it is possible to sterilize articles that are in contact with the hands of the hands in a simple and easy manner. For example, according to the ultraviolet ray sterilizing apparatus of the present invention having only a single sterilizing unit, it is possible to automatically sterilize a surface of a table surface, an operation surface of a mobile phone, or a keyboard of a personal computer (the surface of the flat portion must be sterilized). The surface is sterilized. In addition, according to the ultraviolet ray sterilizing device of the present invention, it is possible to automatically perform a three-dimensional shape such as a sterilized object such as a banknote or a coin that needs to be sterilized on both sides, an article such as a toy for children, a part of a human body such as a palm or a fingertip, and the like. Sterilization of the sterilizing object (the whole surface must be sterilized).

Further, as the ultraviolet light source, since one or more ultraviolet light-emitting diodes are used and the ultraviolet light is emitted as a light source of the strip beam, it is not necessary to spread the UV-LED on the entire surface corresponding to the irradiation region. Configuration, which can reduce the number of UV-LEDs used, is more economical. Especially in the case of using the aforementioned concentrating modularized light source, since a relatively low UV-LED can be used to obtain a high-intensity ultraviolet ray band The beam is shaped so that more efficient sterilization can be performed while tightening the device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the invention is not limited to these ways. In addition, the schema does not necessarily reflect the correct method. In addition, in the figure, there is a case where a part of the symbols are omitted.

Fig. 1 is a perspective perspective view schematically showing the structure of an ultraviolet ray sterilizing apparatus 10 according to an embodiment of the present invention having a first sterilizing unit.

The accommodating portion 16 is provided with a switch 17, by which the light source 100 emits light and the driving device 15 changes the angle of the mirror 14. The dotted line arrow in the figure indicates the direction in which the ultraviolet rays travel.

The ultraviolet irradiation device 10 sterilizes the article as follows. The article to be sterilized (sterilization target) is placed on the upper surface of the ultraviolet ray transmitting window 12 of the ultraviolet ray irradiation device 10, and the switch 17 is opened. When the switch 17 is turned on, the light source 100 emits light and the driving device 15 changes the angle of the mirror 14. The ultraviolet ray emitted from the light source 100 is reflected by the mirror 14 through the ultraviolet ray emitting window 13, and the ultraviolet ray reflected by the mirror 14 is transmitted through the ultraviolet ray transmitting window 12 to be irradiated onto the object to be sterilized. At this time, since the angle of the mirror 14 is constantly changed by the driving device 15, the ultraviolet light reflected by the mirror 14 is scanned (changed) at the position where the ultraviolet ray transmitting window 12 is incident. The ultraviolet rays are irradiated onto the entire sterilization target placed on the ultraviolet ray transmission window 12.

Further, as the power source of the light source 100 and the driving device 15, an external power source or a battery may be used. In the case of a UV irradiation device for carrying, it is preferred to use a battery.

The material constituting the frame 11 is not particularly limited as long as it does not allow ultraviolet rays to pass therethrough, and for example, a metal or a resin can be used. However, it is more preferable that the inner surface of the casing 11 has a surface which is visible from the outer side of the ultraviolet ray transmissive window 12 and which is formed of an ultraviolet ray reflecting material. Examples of the ultraviolet reflective material that can be used in the present invention include chromium (ultraviolet reflectance: about 50%), platinum (ultraviolet reflectance: about 50%), and krypton (ultraviolet reflectance: about 65%). Barium sulfate (UV reflectance: about 95%), magnesium carbonate (UV reflectance: about 75%), calcium carbonate (UV reflectance: about 75%), magnesium oxide (UV reflectance: about 90%), aluminum (UV reflectance: about 90%) and the like. Among these, since a surface having a high reflectance can be formed by surface treatment such as electroplating or vapor deposition, it is particularly preferable to use ruthenium, platinum or aluminum as the ultraviolet reflective material. Further, in the case where a metal material is used as the ultraviolet ray reflection material, it is preferable to transmit ultraviolet ray such as quartz, sapphire or polytetrafluoroethylene film from the viewpoint of preventing a decrease in reflectance due to surface oxidation or scratching. The material is coated to cover the surface of the UV reflective material.

The ultraviolet ray transmitting window 12 has an inner side surface and an outer side surface opposite to the inner side surface, and the inner side surface is disposed inside the frame 11 toward the frame 11 The upper portion of the body 11 penetrates (transmits) the ultraviolet rays emitted from the light source 100 and reflected by the mirror 14 toward the sterilization target placed on the upper portion of the ultraviolet ray transmission window 12. As the material constituting the ultraviolet ray transmitting window 12, for example, sapphire, quartz or the like can be preferably used. In addition, the ultraviolet ray transmission window 12 can be suitably configured by a molded body made of an ultraviolet ray permeable resin or a flexible sheet (or film). Preferred examples of the ultraviolet ray permeable resin include polytetrafluoroethylene, polyethylene, polypropylene, methacrylic resin, epoxy resin, alicyclic polyimide resin, polyamide resin, and polychlorinated chlorine. Ethylene, polyvinyl alcohol resin, etc. (excluding additives such as ultraviolet absorbers or plasticizers that absorb ultraviolet rays used for irradiation).

Further, when the ultraviolet ray permeable window is formed of the ultraviolet ray permeable resin, the resin is deteriorated by the ultraviolet ray irradiation. Therefore, it is preferable that the ultraviolet ray permeable window is detachable from the viewpoint of facilitating the replacement of the ultraviolet ray transmitting window. The ground is installed in the frame.

Further, the ultraviolet ray transmissive window does not necessarily have a flat surface (outer side surface), and may be a curved surface, and may have a concave portion or the like in the vicinity of the center portion for the purpose of facilitating the sterilization target.

The ultraviolet light emission window 13 is provided on one side surface 11a of the casing 11. Although a part of the side surface 11a is used as an ultraviolet light emission window in Fig. 1, the present invention is not limited thereto, and an ultraviolet light emission window may be provided on the entire surface of the side surface 11a. The ultraviolet light emission window 13 can be formed, for example, by a through hole provided in the side wall 11a, and a window made of a material that can be used as the ultraviolet light transmission window can be provided in the through hole.

Barium sulfate (UV reflectance: about 95%), magnesium carbonate (UV reflectance: about 75%), calcium carbonate (UV reflectance: about 75%), magnesium oxide (UV reflectance: about 90%), aluminum (UV reflectance: about 90%) and the like. Among these, since a surface having a high reflectance can be formed by surface treatment such as electroplating or vapor deposition, it is particularly preferable to use ruthenium, platinum or aluminum as the ultraviolet reflective material. Further, in the case where a metal material is used as the ultraviolet ray reflection material, it is preferable to transmit ultraviolet ray such as quartz, sapphire or polytetrafluoroethylene film from the viewpoint of preventing a decrease in reflectance due to surface oxidation or scratching. The material is coated to cover the surface of the UV reflective material.

The drive unit 15 is configured to change the angle of the mirror 14 by opening the switch 17. The angular range of the mirror 14 that is changed by the driving device 15 can be scanned on the entire surface of the ultraviolet ray transmitting window 12 by the reflected light reflected by the ultraviolet ray incident on the mirror 14 from the light source 100, in other words, The incident position of the reflected light emitted from the mirror 14 to the ultraviolet ray transmitting window 12 can be changed to the entire surface of the ultraviolet ray transmitting window 12, and is not particularly limited. The ultraviolet ray sterilizing apparatus 10 of the present invention can adjust the purple color reflected by the mirror 14 by providing the driving device 15. In addition, since the irradiation position of the external line can be automatically irradiated with ultraviolet rays to sterilize the entire object, the operability of sterilization can be improved.

The light source 100 has one or more ultraviolet light-emitting diodes, and emits ultraviolet light as a band-shaped light beam. The length of the strip-shaped light beam emitted from the light source 100 in the width direction is equivalent to the length of the opening provided in the frame body in the same direction as the width direction of the strip-shaped light beam. As shown in FIG. 2, the light source 100 is arranged in a plane by one or more ultraviolet light-emitting diodes 101, 101, ..., and the ultraviolet light is emitted as a band beam. . In this arrangement, the number of the ultraviolet light-emitting diodes arranged in the horizontal (short-end) direction (the number of columns) and the number of the ultraviolet light-emitting diodes arranged in the vertical (long-end) direction (the number of rows) are preferably the vertical / horizontal = two or more, more preferably five or more. Further, although the upper limit of the ratio varies depending on the size of the device, it can be determined depending on the number of ultraviolet light-emitting diodes arranged in the width of the opening of the casing to be described later.

Further, the width of the opening (or the ultraviolet ray transmitting window 12) in the same direction as the width direction of the strip beam represents the maximum width in a direction parallel to the longitudinal direction of the cross section perpendicular to the propagation direction of the strip beam. Although depending on the shape of the opening and the direction in which the light source is provided, for example, when the shape of the opening is a rectangle and the light source is arranged in parallel on the short side (or long side) of the rectangle, the short side (or The length of the long side is the width of the opening. Further, for example, when the shape of the opening is a circle or an ellipse and the light source is arranged in parallel with the diameter of the circle or the major axis (or short axis) of the ellipse, the diameter of the circle or the major axis (or short diameter) of the ellipse The length is the width of the opening.

The light source 100 emits ultraviolet light-emitting diodes when the switch 17 is turned on, and a band beam of ultraviolet light is emitted from the ultraviolet light-emitting window 13 toward the mirror 14. The ultraviolet rays emitted toward the mirror 14 are reflected on the reflecting surface of the mirror 14, and are irradiated onto the object to be sterilized through the ultraviolet ray transmitting window 12. As the ultraviolet light-emitting diode of the present invention, a deep ultraviolet light emitting diode (deep ultraviolet light emitting diode) having an ultraviolet wavelength (deep ultraviolet light) having an irradiation wavelength of 200 to 300 nm, particularly, an irradiation wavelength of 220 nm to 280 nm can be suitably used.

The ultraviolet light emitted from the ultraviolet light emitting diode 101 is straightly advanced in the direction of the optical axis 19 of the ultraviolet light emitting diode 101 by the enhanced directivity of the emitted light. Therefore, by bringing the ultraviolet light emitting diode mounting surface of the substrate 102 toward the reflecting surface of the mirror 14, ultraviolet rays having high intensity can be incident on the reflecting surface of the mirror 14, so that ultraviolet rays having higher intensity can be irradiated to the sterilization surface. The object as a whole.

The outer cover 116 is hermetically or watertightly attached to the cylindrical base member 111 by a sealing member 117 such as a sealant or a gasket, an O-ring or the like, and is sealed with an inert gas or dried in order to improve the durability of the deep ultraviolet LED 112 therein. air.

The deep ultraviolet LEDs 112, 112, ... are arranged to emit ultraviolet rays in a fixed direction in a state in which the components are mounted on the sub-carriers or in a state in which they are housed in the package. Further, although not shown, a sub-carrier or a package is formed with a wiring for supplying electric power from the outside of the module to the deep ultraviolet LED 112 or a circuit for causing the deep ultraviolet LED 112 to operate normally, to the wiring or the circuit. The power supply is performed via wiring formed on the surface or inside of the cylindrical substrate 111.

The cylindrical base body 111 has a function as a heat sink in addition to the function as a support for fixing and holding the deep ultraviolet LED 112. By circulating the cooling medium 118 such as cooling water or cooling air to the internal cooling medium flow path 113, temperature rise due to heat generated by the deep ultraviolet LED 112 can be prevented, contributing to stable operation of the element and extending the life of the element. . When the light source 100' is used in the ultraviolet ray sterilizing apparatus of the present invention for carrying, it is preferable to provide a small fan and to supply the cooling air to the cooling medium flow path 113 as the cooling medium 118.

In order to efficiently remove the heat generated by the deep ultraviolet LED 112, the cylindrical base body 111 is preferably made of a metal or ceramic having high thermal conductivity such as copper or aluminum, and is used to increase the cooling medium 118. It is preferable that the heat exchange area is grooved on the inner wall surface of the cooling medium flow path 113. Further, when the cylindrical base body 111 is made of a metal material, it is preferable to form a copper wire for supplying electric power to the deep ultraviolet LED 112 from a battery or an external power source disposed inside or outside the casing or The loop reaches the insulating insulation.

On the side surface of the cylindrical substrate 111, a plurality of deep ultraviolet LEDs 112, 112, ... are arranged such that the optical axis 115 of each deep ultraviolet LED 112 passes through the central axis 114 of the substrate 111 along the circumferential direction thereof. As a result, the deep ultraviolet rays emitted from the deep ultraviolet LEDs 112 are radially emitted to the central axis 114. Further, the optical axis 115 of the deep ultraviolet LED 112 means the central axis of the light emitted from the deep ultraviolet LED 112, and is substantially synonymous with the forward direction of the light. In addition, the term "the optical axis 115 is disposed so as to pass through the central axis 114 of the base 111" means that the optical axis 115 is disposed as much as possible in such a state, and there is no problem even if it is slightly inclined from this state.

In the third drawing, although the example in which four deep ultraviolet LEDs are arranged in the circumferential direction of the substrate 111 is shown, the configuration is not limited thereto, and the number of the deep ultraviolet LEDs 112 can be set according to the outer diameter of the cylindrical substrate 111. Make appropriate changes. Although the number of deep ultraviolet LEDs 112 arranged in the circumferential direction is usually in the range of 3 to 20, preferably 4 to 12, the number of deep ultraviolet LEDs 112 arranged in the circumferential direction is larger. The higher the intensity (photon flux density) of the deep ultraviolet rays emitted from the light source 100', the larger the diameter of the cylindrical substrate 111 can be increased in the case of requiring deeper ultraviolet light of higher intensity, so that the arrangement is The number of ultraviolet light-emitting elements in the circumferential direction is increased to exceed the above range.

The deep ultraviolet LEDs 112, 112, ... are preferably arranged in a row in the longitudinal direction of the cylindrical substrate 111 as shown in the longitudinal cross-sectional view of Fig. 3. At this time, in order to make the intensity in the deep ultraviolet light irradiation region uniform, the deep ultraviolet LEDs 112, 112, ... are preferably arranged so as to be closely and orderly arranged on the side surface of the cylindrical substrate 111.

4 and 5 show a cross-sectional view and a side view of a light source 100' having a rod-shaped light source 110. The light source 100' has a body 150, and the rod-shaped light source 110 is disposed inside the body 150. The body 150 has an emission side frame 125, and an inner surface is formed with an exit side mirror 120 composed of a long elliptical mirror; The side frame body 126 has a condensing side mirror 123 formed of a long elliptical mirror on the inner surface and forms a deep ultraviolet light emitting opening 130; the collimating optical system 140 is disposed in the deep ultraviolet light emitting opening. 130. In the main body 150, it is preferable that the emission side frame body 125 and the light collecting side frame body 126 are detachably or hinged or the like to form an openable and closable. Moreover, the main body 150 is provided with an outer cover (not shown) for preventing ultraviolet rays from leaking to the outside in the opening portions at both end portions in the lower direction of the paper surface of Fig. 5 .

In the aspects shown in FIGS. 4 and 5, since the exit side mirror 120 and the condensing side mirror 123 are substantially elliptical mirrors having substantially the same shape, the main body 150 emits the side frame 125 and Concentrating side The shape of the internal space formed by the combination of the frame 126 is an elliptical cross section in which the two axes of the focal axis 121 of the exit side mirror and the collecting axis 122 of the exit side mirror respectively form a focal axis (wherein the opening is equivalent to the opening) Part of the portion 130 is missing.) The columnar body. The surface of the emission side mirror 120 and the condensing side mirror 123 is preferably a material having a high reflectance to deep ultraviolet light, for example, a platinum group metal such as Ru, Rh, Pd, Os, Ir, or Pt, or Al. , Ag, Ti, an alloy containing at least one of these metals, or magnesium oxide. From the reason of particularly high reflectivity, it is particularly preferable to use Al, a platinum group metal or an alloy containing a platinum group metal, or magnesium oxide. To form.

In the concentrating side mirror 123 and the condensing side frame 126, the deep ultraviolet light emitting opening 130 is provided in a slit shape, and the illuminating ultraviolet ray is converted into a parallel or slightly parallel light beam. Collimating optical system 140. The collimating optical system 140 is preferably made of a material having high ultraviolet ray permeability such as synthetic or natural quartz, sapphire, or ultraviolet ray permeable resin. The collimating optical system 140 is preferably detachably attached to the deep ultraviolet light emitting opening 130.

On the light source 100', the rod-shaped light source 110 is disposed such that its central axis 114 coincides with the focal axis 121 of the exit side mirror. Since the rod-shaped light source 110 is disposed at such a position, the deep ultraviolet light radiated from the rod-shaped light source 110 is reflected by the emission side mirror 120 and the condensing side mirror 123, and is condensed to be reflected on the condensing side. The focus axis 124 of the mirror (in other words, the collecting axis 122 of the exit side mirror) is collected, and the concentrated deep ultraviolet light is emitted from the ultraviolet light emitting window 13 toward the mirror 14.

In this way, in the light source 100', in principle, it can be All of the deep ultraviolet light that is radially emitted from the rod-shaped light source 110 is condensed on the focus axis 124 of the condensing side mirror 123, and the direction that does not face the direction of the deep ultraviolet light emitting opening 130 (for example, the opposite direction) can be effectively utilized. Or horizontally) the ultraviolet rays emitted. In other words, in the rod-shaped light source 110, it is not necessary to arrange all of the deep ultraviolet LEDs 112, 112, ... on the same plane to make the optical axis 115 toward the deep ultraviolet light emitting opening 130, or to the lateral direction or The opposite direction is configured. Therefore, the number of ultraviolet light-emitting elements per unit space can be greatly increased in the rod-shaped light source 110, and the light source 100' can emit ultraviolet rays having higher intensity. In addition, it is not necessary to use a large aperture field of view lens on the light source 100'. Further, in the light source 100', the irradiation region is not narrow, but ultraviolet rays of uniform intensity can be irradiated to the rectangular region having a long side. Therefore, the surface of the object to be sterilized can be uniformly sterilized by deep ultraviolet light. Further, since the deep ultraviolet light can be emitted as a collimated parallel light beam, even when the optical path length from the light source 100' to the surface of the sterilization target is long, the intensity of the deep ultraviolet light is not easily lowered.

In the above description of the present invention, a mirror 14 having a structure in which a cylinder is vertically cut and has a cross-sectional shape as a reflecting surface is provided, and the driving device swings the mirror (the angle of the mirror 14 is changed). The sterilization device 10 is not limited to this embodiment.

Further, the mirror device may be configured such that the mirror-shaped mirror having the double-sided reflecting surface is rotated by the driving device, and the mirror is moved in a direction intersecting the width direction of the strip-shaped light beam by the mirror rotating shaft. The constructed ultraviolet sterilization device.

By sliding the plate mirror (preferably at a high speed) while rotating, the scanning mechanism can shift the incident position of the ultraviolet light from the light source toward the ultraviolet ray transmitting window toward the width direction of the strip beam. When the ultraviolet light from the light source is irradiated from the inside of the casing, the incident angle of the ultraviolet ray to the inner side surface of the ultraviolet ray transmitting window is changed, and the ultraviolet ray irradiation region is irradiated with ultraviolet light at two or more different incident angles in an arbitrary ultraviolet ray irradiation region. Further, in such a case, the surface of the object to be sterilized can be scanned while irradiating the ultraviolet ray at various angles from the lower side (the ultraviolet ray transmitting window side) of the sterilizing target, thereby sterilizing the surface with irregularities. The object is more sterilized. In this aspect, it is preferable to configure the light source so that the strip beam can always be irradiated on the mirror regardless of the position of the plate mirror, or the angle at which the light source is emitted from the strip beam is changed synchronously with the sliding movement of the mirror, so that Regardless of the position of the plate mirror, the ribbon beam can always illuminate the mirror.

In the above description of the present invention, the ultraviolet ray sterilizing apparatus 10 having the form of the box-shaped housing 11 is exemplified, but the present invention is not limited to this embodiment. The shape of the frame is not particularly limited, and may be, for example, a box shape, or may be, for example, a cylindrical shape. In addition, as disclosed in Japanese Laid-Open Patent Publication No. 2007-124124 (Patent Document 4), The inner frame made of a shape memory alloy is formed of an inserted flexible material and bonded to a frame having a shape of an inner frame shape of the memory recovery element.

For example, when a rectangular opening is formed in a part of the upper surface of the casing, the casing may be a square casing, and the casing whose opening is aligned with the opening of the casing may be provided inside the casing. A mirror or ultraviolet transmission window is disposed inside the cabinet.

In the above description of the present invention, the ultraviolet irradiation device 10 having no ultraviolet opaque cover for preventing ultraviolet rays emitted from the light source from leaking to the outside is exemplified, but the present invention is not limited to this embodiment. For example, it may be configured to further include an ultraviolet-impermeable cover for preventing leakage of ultraviolet rays emitted from the light source to the outside (hereinafter referred to as a "cover"), and the outer surface of the window through the ultraviolet ray An ultraviolet ray sterilizer in which a sterilizing target is disposed in a space between the outer surface of the ultraviolet ray permeable window and the ultraviolet opaque cover is surrounded by the ultraviolet opaque cover.

Fig. 6(A) is a plan view of the ultraviolet ray sterilizing apparatus 1010, and Fig. 6(B) is a cross-sectional view taken along line A-A of Fig. 6(A). In the sixth (A) and sixth (B) drawings, the same elements as those already indicated in FIGS. 1 to 5 are given the same symbols as those in the first to fifth figures. And the description is omitted. The ultraviolet ray sterilizing device 1010 is an ultraviolet ray sterilizing device having a form of a second sterilizing unit.

The ultraviolet ray sterilizing apparatus 1010 includes an ultraviolet ray sterilizing unit having a housing 11 having an opening, and an ultraviolet ray transmitting window 12 that is transparent to ultraviolet rays and has an inner side surface 12a and an outer side surface 12b opposite to the inner side surface 12a. The inner side surface 12a is disposed inside the casing 11 so as to close the opening of the casing 11, the light source 100 emits ultraviolet light as a band-shaped light beam, and the scanning mechanism is provided by the light source 100 from one side. When ultraviolet rays are incident on the ultraviolet ray transmitting window 12, the ultraviolet light from the light source 100 is irradiated while shifting in a direction intersecting the width direction of the strip beam, and ultraviolet rays from the light source 100 can be irradiated from the inside of the housing 11 through the ultraviolet ray transmitting window. The entire surface of the inner side surface 12a of 12 is irradiated with ultraviolet rays to sterilize the sterilizing object disposed to face the outer side surface 12b of the ultraviolet ray transmitting window 12. The ultraviolet ray sterilizing device 1010 may further have the ultraviolet opaque outer cover described above.

The moving mechanism 1015 includes an electric motor 1015a and a set of guide rails 1015b and 1015b (hereinafter, simply referred to as "rail 1015b"). The light source 100 is held by the guide rail 1015b, and is driven by the electric motor 1015a to reciprocate (slidely move) in the direction of the arrow B of the sixth (A) diagram on the guide rail 1015b. In the mechanism for converting the rotational driving force of the electric motor 1015a into the linear driving force along the guide rail 1015b, the rack and pinion mechanism and the crank can be used without any particular limitation.

In the above description of the present invention, the ultraviolet ray sterilizing apparatus 1010 having the light source 100 in which the ultraviolet light emitting diodes 101, 101, ... are directly irradiated to the ultraviolet ray transmitting window 12 in the form of a strip light beam is exemplified. However, the present invention is not limited to this form. For example, a unit type light source in which both the ultraviolet light emitting diode and the mirror are combined may be used instead of the light source 100, and the ultraviolet ray sterilizing device in a form of sliding movement along the guide rail. Fig. 7 is a view schematically showing a light source 1100 according to one of the other modes. Fig. 7(A) is a plan view of the light source 1100, and Fig. 7(B) is a C-C cross-sectional view of Fig. 7(A).

The light source 1100 has a substrate 102; ultraviolet light-emitting diodes 101, 101, ... are arranged on the substrate 102; and the light guide 1111 is emitted from the ultraviolet light-emitting diodes 101, 101, ... The light is diffused; the mirror 1114 is disposed at a position where the ultraviolet light emitted from the light guide 1111 is incident; and the retainer 1110 is the substrate 102, the ultraviolet light emitting diode 101, 101, ..., the light guide The 1111 and the mirror 1114 are housed and held in a predetermined positional relationship. The retainer 1110 is attached to the guide rail 1015b (see Fig. 6), and is driven to slide along the guide rail 1015b by the electric motor 1015a. The strip-shaped light beams emitted from the ultraviolet light-emitting diodes 101, 101, ... are diffused by the light guide body 1111, and are reflected by the mirror group 1114 as shown by the arrow group D of Fig. 7(B) The light beam is incident on the ultraviolet ray transmitting window 12 while being scattered in the thickness direction.

a haplotype that combines an ultraviolet light emitting diode and a mirror in this manner The light source 1100 can freely set the angle at which the strip beam is incident on the ultraviolet ray transmissive window 12. Further, since the strip-shaped light beam is incident on the ultraviolet ray transmitting window 12 while being dispersed in the thickness direction like the arrow group D of the seventh (B) drawing, the ultraviolet ray can be moved from the different two by the light source 1100 sliding along the guide rail 1015b. The above angle is irradiated to any of the irradiation sites of the sterilization target. In other words, by means of a compact device structure, "by changing the incident angle of the ultraviolet rays to the inner side surface of the ultraviolet ray transmitting window, the ultraviolet ray irradiation region of the sterilizing object is irradiated with ultraviolet rays at two or more different incident angles." .

Further, for example, an ultraviolet ray sterilizer in a form in which a light source 100 or a light source 1100 is replaced by a unit light source in which both the ultraviolet light emitting diode and the rotating mirror are combined, and is slidably moved along the guide rail may be used. Fig. 8 is a view schematically showing a light source 1200 according to one of the other modes. Fig. 8(A) is a plan view of the light source 1200, and Fig. 8(B) is an E-E arrow view of Fig. 8(A).

The light source 1200 has a support 1210, a substrate 102, ultraviolet light-emitting diodes 101, 101, ... arranged on the substrate 102, and a plate-shaped mirror 1214 disposed on the ultraviolet light-emitting diodes 101, 101. The position at which the emitted ultraviolet light is incident, the double-sided surface has a reflecting surface; the shafts 1215a, 1215b are disposed at both ends of the mirror 1214; the driven pulley 1216 is penetrated by the shaft 1215a and fixed to the shaft 1215a; The electric motor 1217; the drive pulley 1218 is rotated by the electric motor 1217; and the belt 1219 is wound around the drive pulley 1218 and the driven pulley 1216 to transmit the rotation of the drive pulley 1218 to the driven pulley 1216. axis 1215a, 1215b are rotatably held by bearings (not shown) provided on the side wall of the retainer 1210. The retainer 1210 is held in a predetermined positional relationship by accommodating the above-described members. The rotational force of the electric motor 1217 is transmitted to the shaft 1215a provided at the end of the mirror 1214 via the drive pulley 1218, the belt 1219, and the driven pulley 1216, and the mirror 1214 is rotated in the direction of the arrow F of the eighth (B) diagram. . The strip-shaped light beams emitted from the ultraviolet light-emitting diodes 101, 101, ... are reflected by the plate-shaped mirror 1214 having a reflecting surface on both sides and are incident on the ultraviolet light transmitting window 12. Since the mirror 1214 is rotated by the electric motor 1217 and the angle of the mirror 1214 is constantly changed, the angle at which the strip beam reflected by the mirror 1214 is incident on the ultraviolet ray transmissive window 12 is constantly changed. At the same time, the retainer 1210 is attached to the guide rail 1015b (refer to Fig. 6), and is driven to slide along the guide rail 1015b by the electric motor 1015a.

Even if the ultraviolet ray sterilizing device having the light source 1210 is in a state in which the ultraviolet ray from the light source 1210 is incident on the ultraviolet ray transmitting window 12, the light source is shifted in a direction intersecting the width direction of the strip light beam. When the ultraviolet ray of 1210 is irradiated from the inside of the casing 11, the incident angle of the ultraviolet ray to the inner side surface 12a of the ultraviolet ray transmitting window 12 is changed, and the ultraviolet ray irradiation region of the sterilizing object can be irradiated with ultraviolet rays at two or more different incident angles. .

In the above description of the present invention, the ultraviolet ray sterilizing apparatus 1010 that slidably moves the light source 100 (or the light source 1100/1200) along a plane determined by the set of the guide rails 1015b and 1015b is used. However, the present invention does not. Limited to this form. For example, it can also be a light source An ultraviolet sterilizer that slides along a curved surface.

Fig. 9(A) is a plan view of the ultraviolet ray sterilizing apparatus 2010, and Fig. 9(B) is a G-G sectional view of Fig. 9(A). Further, although the posture of the plurality of light sources 100 can be described in the ninth (B) diagram, this does not mean that the ultraviolet ray sterilizing device 2010 has a plurality of light sources 100.

The ultraviolet ray sterilizing device 2010 is an ultraviolet ray sterilizing device having a form of a third sterilizing unit. In the ultraviolet ray sterilizing apparatus 2010, the light source 100 is a curved surface which is formed by a cylindrical surface, an elliptical cylinder surface or a parabolic cylindrical surface and which is concavely curved as viewed from the side of the sterilization target (the side of the ultraviolet ray transmission window 2012). A) Sliding movement in the direction of the arrow H of the figure. The ultraviolet ray sterilizing device 2010 is different from the ultraviolet ray sterilizing device 1010 in that a pair of curved guide rails 2015b and 2015b (hereinafter referred to as "rails 2015b") are replaced by a pair of linear guide rails 1015b, The point of 1015b and the curved-wall ultraviolet light transmission window 2012 which protrudes toward the inside of the frame 11 are replaced by the point of the flat-shaped ultraviolet-ray transmission window 12. The pair of curved guide rails 2015b and 2015b are curved surfaces which are defined by a cylindrical surface, an elliptical cylinder surface or a parabolic cylindrical surface and which are concavely curved from the side of the sterilization target (the side of the ultraviolet window 2012), and the light source 100 is subjected to the edge. The curved surface defined by the guide rail 2015b is slidably moved by the driving force of the electric motor 1015a. According to the ultraviolet ray sterilizing device 2010, as shown by the arrow group I in Fig. 9(B), the angle of the ultraviolet light band incident on the ultraviolet ray transmitting window 2012 can be changed by the irradiation position. change.

Further, even in the ultraviolet ray sterilizer in which the light source is slidably moved along the curved surface defined by the guide rail curved like the guide rail 2015b, the ultraviolet ray permeable window having the flat shape like the ultraviolet ray permeable window 12 described above can be formed.
