Description

How to install sterilizer, lighting and sterilization equipment, and sterilizer

This disclosure relates to a sterilization device, lighting and sterilization equipment, and a method of installing the sterilization device.

Conventionally, a sterilization device that sterilizes air by using a photocatalyst has been proposed. The sterilization device (“photocatalyst device” in the text) described in Patent Document 1 includes a housing, a photocatalyst member, a blower (“fan” in the text), and a light source (“LED light” in the text).
The housing has a rectangular shape, and contains two photocatalytic members in each net shape, a blower, and a light source. The housing is provided with a hooking portion. The user hangs the sterilizer from an appropriate position by passing a string or rope through the hook. An outlet and a suction port are provided on the upper surface and the lower surface of the housing.

The two photocatalyst members are separated from each other by an appropriate length and face each other in the front-rear direction. The light emitted by the light source irradiates the two photocatalyst members. When the photocatalyst member is irradiated with light, active oxygen is generated, and germs contained in the air are decomposed and removed by the active oxygen.
The air sucked from the suction port flows between the two photocatalyst members to be sterilized by the blower of the blower, and is blown out from the outlet.

Japanese Unexamined Patent Publication No. 2020-44506

For example, when a sterilizing device is used in a commercial facility (supermarket, department store, etc.), it is possible to give a sense of security to the visitor that the air is sterilized. In the case of the sterilizing device described in Patent Document 1, it is conceivable to suspend the sterilizing device from the wall of a commercial facility, a display fixture, or the like.
However, the sterilizing device described in Patent Document 1 is provided with a rectangular housing, and may give a sense of discomfort to the viewer depending on the interior or atmosphere of the commercial facility.
However, if the sterilizer is blindfolded, the visitor may misunderstand that the air has not been sterilized.

An object of the present disclosure is to provide a sterilizing device, a lighting and sterilizing device, and a method for installing the sterilizing device, which easily match the appearance of the installation site.

The sterilization device according to the present disclosure is a sterilization device used in a place where a spotlight is used, and is sucked into the inside of the housing through a tubular housing and one opening of the housing. A blower that blows air so as to blow out from the other opening of the housing, a photocatalyst member that the air passing through the inside of the housing comes into contact with, a light source for irradiating the photocatalyst member with light, and the above. The housing is provided with a support that supports the housing and is mounted at a mounting position to which the spotlight can be mounted, and the blower, the photocatalyst member, and the light source are built in the housing.

In the present disclosure, the housing has a cylindrical shape.
The light emitted by the light source irradiates the photocatalyst member, and active oxygen is generated around the photocatalyst member.
When the blower blows air, the air sucked from one opening of the housing passes through the inside of the housing. The air flowing inside the housing comes into contact with the photocatalyst member and is sterilized by the active oxygen generated around the photocatalyst member. The sterilized air is blown out from the other opening of the housing.

Since the blower, photocatalyst member, and light source are built in the housing, the appearance of the sterilizer is a cylinder supported by the support. Therefore, the appearance of the sterilizer can be made to resemble the appearance of a general spotlight provided with a cylindrical housing and a support for the housing.

Where the spotlight is used (eg, a commercial facility), the support is mounted at a mounting position where the spotlight can be mounted (eg, the ceiling of the commercial facility, or a wiring rail suspended and supported by the ceiling). Then, it looks as if the sterilizer is a spotlight. That is, the sterilizer tends to match the appearance of the installation location.
Since the sterilizer that easily matches the appearance of the installation location does not give the viewer a sense of discomfort, there is no need to hide the sterilizer. Therefore, if you look for it, you can find a sterilizer, so it is easy to confirm that the air is sterilized.

In the sterilization device according to the present disclosure, the housing is supported by the support and is separably connected to the first cylinder in which the blower and the light source are built and the first cylinder. It is characterized by including a second cylinder in which the photocatalyst member is built.

In the present disclosure, the housing is formed by connecting the second cylinder to the first cylinder.
A blower and a light source are built in the first cylinder. That is, since the objects that require power supply are grouped in the first cylinder, wiring from the power supply to the blower and the light source is easy. Since the first cylinder is supported by the support, it is also possible to wire the power supply member for supplying power to the blower and the light source along the support.

A photocatalyst member is built in the second cylinder. The second cylinder can be removed from the first cylinder. When removing the second cylinder, it is not necessary to remove the first cylinder from the support or the support from the mounting position. Therefore, it is easy to replace or clean the photocatalyst member.

In the sterilization apparatus according to the present disclosure, the light source emits visible light or ultraviolet light, and the visible light emitted by the light source is transmitted as it is to the outside of the housing, or the ultraviolet light emitted by the light source is converted into visible light. It is characterized by further including a translucent body that is converted and then transmitted to the outside of the housing.

In the present disclosure, the light source emits visible light or ultraviolet light.
When the light source emits visible light, the translucent body transmits the visible light emitted by the light source to the outside of the housing as it is. When the light source emits ultraviolet rays, the translucent body converts the ultraviolet rays emitted by the light source into visible light and then transmits the ultraviolet rays to the outside of the housing.

In any case, when the light source is emitting light, the translucent body appears to be shining. Whether or not the translucent body appears to be shining indicates whether or not the light source is emitting light, that is, whether or not the air blown out from the housing is sterilized. Therefore, a light source inside the housing can be used to indicate whether or not the bacteria are being sterilized on the outside of the housing.

The sterilization apparatus according to the present disclosure is characterized in that a plurality of the light sources are arranged in the circumferential direction of the housing.

In the present disclosure, since a plurality of light sources are arranged in the circumferential direction of the housing, the light emitted by the light source can be evenly applied to the photocatalyst member in the circumferential direction of the housing. Therefore, active oxygen can be effectively generated over the circumferential direction of the housing.

The sterilization device according to the present disclosure is characterized in that the support has a support main body attached to the housing and a mounting portion detachably attached to the support main body and attached to the attachment position. And.

In the present disclosure, the support includes a support body and a mounting portion.
The support body is attached to the housing. The mounting part is attached to and detached from the support body.
The mounting part mounted on the support body is mounted at the mounting position. Therefore, the sterilizing device can be mounted at any mounting position by mounting the mounting portion according to the configuration of the mounting position on the support main body.

The sterilization apparatus according to the present disclosure is characterized in that an air throttle is built in the blower of the housing, the photocatalyst member, and the air throttle on the downstream side of the photocatalyst member.

In the present disclosure, an air throttle is further built in the housing. The air throttle is arranged on the downstream side of the blower, the photocatalyst member, and the photocatalyst member.
Since the air flow is throttled by the air throttle, the sterilized air blown out from the housing can reach a long distance without being diffused over a very wide area.

The lighting and sterilization equipment according to the present disclosure includes a tubular housing having a built-in light source that emits visible light, a spotlight having a support for supporting the housing, and a sterilization device according to the present disclosure. The spotlight and the support for each of the sterilizers are attached, and the spotlight and the sterilizer are provided with a wiring rail to which a feeding member for feeding the sterilizer is wired.

In the present disclosure, the spotlight and the sterilizing device according to the present disclosure both include a cylindrical housing and a support for the housing. A wiring rail is provided at the place where the spotlight is used, and a support for the spotlight and the disinfectant device is attached to the wiring rail. Therefore, in terms of appearance, the sterilizer is easily mixed with the spotlight, and it is easy to match the appearance of the installation location.

In the sterilizer, a power feeding member for supplying power from the wiring rail to the blower and the light source built in the housing can be wired along the support tool interposed between the wiring rail and the housing. Similarly, in the spotlight, a power feeding member for supplying power to the light source built in the housing can be wired along the support.

In the lighting and sterilization equipment according to the present disclosure, the color of the housing of the spotlight and the sterilizer is the same as each other, and the shape and color of the support of the spotlight and the sterilizer are different. It is characterized by being the same as each other.

In the present disclosure, the housing provided in the spotlight and the housing provided in the sterilizing device are both cylindrical and have the same color.
Further, the support provided by the spotlight and the support provided by the sterilizer have the same shape and color.
That is, since the appearances of the spotlight and the sterilizer are similar to each other, there is no sense of discomfort even if the spotlight and the sterilizer are mixed.

The method for installing the sterilizer according to the present disclosure is a tubular housing and air blown from one opening of the housing so that air sucked into the inside of the housing is blown out from the other opening of the housing. A blower, a photocatalyst member that comes into contact with air flowing inside the housing, a light source for irradiating the photocatalyst member with light, and a mounting position that supports the housing and allows a spotlight to be mounted. Prepare a sterilizer with a support to be attached, the blower, the photocatalyst member, and the light source built into the housing, at a location where each of the plurality of spotlights is attached to the attachment position. The sterilization device is installed by removing a part of the plurality of spotlights from the mounting position and mounting the support at the mounting position from which the spotlight has been removed.

In the present disclosure, lighting and sterilization equipment can be easily obtained by replacing at least one spotlight with the sterilization device according to the present disclosure at a place where a plurality of spotlights are mounted at the mounting positions. be able to.

It is a perspective view of the sterilization apparatus which concerns on Embodiment 1. FIG. It is a side view of a sterilizer. It is an exploded perspective view of a sterilizer. It is a perspective view of the lighting and sterilization equipment. It is an exploded side view of the sterilization apparatus which concerns on Embodiment 2. FIG.

Hereinafter, embodiments of the present disclosure will be described.

Embodiment 1.
FIG. 1 is a perspective view of the sterilization apparatus according to the first embodiment.
FIG. 2 is a side view of the sterilizer.
In the figure, 1 is a sterilizing device, and the sterilizing device 1 includes a housing 2 and a support 3.
The housing 2 has a cylindrical shape.
In the following, one opening of the housing 2 is referred to as a suction port 2a, and the other opening of the housing 2 is referred to as an outlet 2b.
The housing 2 includes four cylinders 21 to 24.

FIG. 3 is an exploded perspective view of the sterilizing device 1. In FIG. 3, a part of the sterilizing device 1 is broken and shown.
As shown in FIGS. 2 and 3, the opening at one end of the tubular body 21 is a suction port 2a.
A male screw is provided on the outer peripheral surface of the other end of the cylinder 21.
A guard member 211 is fixed to the inner peripheral surface of the tubular body 21. The guard member 211 prevents foreign matter (for example, insects) from entering the inside of the housing 2 from the suction port 2a. The guard member 211 does not block the inflow of air into the housing 2. The guard member 211 is, for example, a louver.

A blower 221 and a light source member 222 are fixed to the inner peripheral surface of the cylinder 22 (first cylinder). The light source member 222 and the blower 221 are adjacent to each other with an appropriate length separation in the axial length direction of the tubular body 22.
The blower 221 is a propeller fan, which is coaxially arranged on the cylinder 22. The blower 221 blows air from the opening on the blower 221 side of the cylinder 22 toward the opening on the light source member 222 side of the cylinder 22.

The light source member 222 includes a band-shaped wiring board and an LED 223 (light source) mounted on one surface of the wiring board. A plurality of LEDs 223 are arranged in the length direction of the light source member 222. FIG. 3 shows a case where the LEDs 223 are also arranged in the width direction of the light source member 222. The light source member 222 extends over the entire circumference of the tubular body 22. The surface on which the LED 223 is mounted is oriented toward the axis of the cylinder 22.
The LED 223 emits visible light or ultraviolet light.

A female screw into which a male screw of the cylinder 22 can be screwed is provided on the inner peripheral surface of one end of the cylinder 22 on the blower 221 side.
A male screw similar to the male screw of the tubular body 22 is provided on the outer peripheral surface of the other end of the tubular body 22 on the light source member 222 side.

A translucent body 224 is provided on the outer peripheral surface of the tubular body 22 (see FIGS. 1 and 2). The translucent body 224 forms an annular shape over the entire circumference of the tubular body 22, and is made of, for example, an acrylic resin.
The cylinder 22 is provided with a slit 225 extending in the circumferential direction of the cylinder 22. A plurality of slits 225 are arranged in the circumferential direction of the cylinder 22. The opening of the slit 225 on the outer peripheral surface of the tubular body 22 is closed by the translucent body 224.
A part of the light emitted by the LED 223 is incident on the translucent body 224 through the slit 225.

When the LED 223 emits visible light, the visible light incident on the translucent body 224 from the inside of the tubular body 22 passes through the translucent body 224 as it is and is emitted to the outside of the tubular body 22.
When the LED 223 emits ultraviolet rays, for example, a particulate phosphor that absorbs ultraviolet rays and emits visible light is contained in the translucent body 224. Ultraviolet rays incident on the translucent body 224 from the inside of the tubular body 22 are converted into visible light, transmitted through the translucent body 224, and emitted to the outside of the tubular body 22.

When the LED 223 emits visible light together with ultraviolet rays, an optical filter that allows visible light to pass through and does not transmit ultraviolet rays may be arranged in each slit 225. In this case, it is not necessary for the translucent body 224 to contain the above-mentioned phosphor.

A photocatalyst member 231 is fixed to the inner peripheral surface of the cylinder 23 (second cylinder). The photocatalyst member 231 has a photocatalytic function and does not obstruct the flow of air. For example, the photocatalyst member 231 includes a cylinder internally fitted in the cylinder 23 and a net covering the openings at both ends of the cylinder. The cylinder and net carry a particulate photocatalyst, or the cylinder and net are made of photocatalyst.
The photocatalyst member 231 is activated by receiving visible light or ultraviolet rays. The activated photocatalyst member 231 generates active oxygen from oxygen in the air and water. The LED 223 emits light that activates the photocatalyst member 231.

A female screw similar to the female screw of the cylinder 22 is provided on the inner peripheral surface of one end of the cylinder 23.
On the outer peripheral surface of the other end of the cylinder 23, a male screw similar to the male screw of the cylinder 22 is provided.

A female screw similar to the female screw of the cylinder 22 is provided on the inner peripheral surface of one end of the cylinder 24.
The opening at the other end of the cylinder 24 is the outlet 2b.
A rectifying grid 241 is fixed to the inner peripheral surface of the cylinder 24. The rectifying grid 241 rectifies the flow of air.

The cylinders 21 and 22 are connected to each other by screwing a male screw and a female screw. Similarly, the cylinders 22, 23 (and the cylinders 23, 24) are connected to each other by screwing a male screw and a female screw. The housing 2 is formed by connecting the cylinders 21 to 24 so as to be arranged in this order and connected to each other (see FIGS. 1 and 2).
The guard member 211, the blower 221, the light source member 222, the photocatalyst member 231 and the rectifying grid 241 are arranged in this order from the suction port 2a toward the outlet 2b.

As shown in FIGS. 1 to 3, the support 3 includes a support main body 31 and a mounting portion 32.
The support body 31 includes an arm 311, a fixed body 312, and an Axis 313.
The arm 311 has a straight rod shape. One end of the arm 311 is bifurcated.
The fixed body 312 is sandwiched between the bifurcated portions of the arm 311 so that a part thereof protrudes from the arm 311. The protruding portion of the fixed body 312 from the arm 311 is fixed (for example, welded) to the tubular body 21 of the housing 2.
The tubular body 21 may be provided with the fixed body 312 instead of the support main body 31. In this case, the fixed body 312 is integrally provided with the tubular body 21, for example, when the tubular body 21 is formed.

The pivot 313 penetrates the bifurcated portion of the arm 311 and the fixed body 312 perpendicularly to the length direction of the arm 311. The axial length direction of the pivot axis 313 is orthogonal to the axial length direction of the housing 2. The fixed body 312 can swing within a predetermined range about the pivot 313. Since the fixed body 312 is fixed to the tubular body 21, the tilt angle of the housing 2 can be changed around the pivot axis 313. The tilt angle of the housing 2 is held, for example, by friction between the fixed body 312 and the arm 311 and the pivot 313.

The mounting portion 32 has a cylindrical shape and includes a screw portion 321 and a mounting shaft 322. The screw portion 321 and the mounting shaft 322 project from both ends of the mounting portion 32 in the axial length direction in directions opposite to each other and coaxially with the mounting portion 32.
As shown in FIG. 3, a screw hole 314 is provided in the other end of the arm 311 (the end that is not bifurcated) in the longitudinal direction of the arm 311. The mounting portion 32 is detachably mounted on the support main body 31 by screwing the screw portion 321 and the screw hole 314 of the arm 311.

As shown in FIG. 2, an engaging piece 323 is provided on the peripheral surface of the base end portion of the mounting shaft 322, and a connection terminal 324 is provided on the peripheral surface of the tip end portion of the mounting shaft 322. The engaging piece 323 and the connecting terminal 324 each have a flange shape.
The connection terminal 324, the blower 221 and the light source member 222 are electrically connected to each other via a metal feeding member 11. The feeding member 11 is wired along the support 3. The power feeding member 11 arranged in the mounting portion 32 and the feeding member 11 arranged in the support main body 31 are electrically connected by screwing the screw portion 321 and the screw hole 314.

FIG. 4 is a perspective view of the lighting and sterilization equipment.
In the figure, 4 is a lighting and sterilizing facility, and the lighting and sterilizing facility 4 includes a sterilizing device 1, a wiring rail 5 (mounting position), and a spotlight 6.
As shown in FIGS. 2 and 4, the wiring rail 5 has a square cylinder shape and is suspended and supported by the ceiling 71 of a commercial facility.
A string-shaped hanging tool 72 is hung from the ceiling 71. A plurality of hanging tools 72 are arranged side by side in one direction. The wiring rail 5 is held at the lower end of each hanging tool 72 so as to extend parallel to the floor (not shown) of the commercial facility.

As shown in FIG. 2, a slit 51 is provided on the lower surface of the wiring rail 5 over the entire length.
Two power feeding members 52 are wired over the entire length inside the wiring rail 5. One feeding member 52 is along one side surface of the wiring rail 5, and the other feeding member 52 is along the other side surface of the wiring rail 5. Each feeding member 52 has a U-shaped cross section. The U-shaped openings of the two feeding members 52 face each other.

The mounting portion 32 of the support 3 of the sterilizing device 1 is detachably attached to the wiring rail 5. For example, the mounting shaft 322 of the mounting portion 32 is inserted into the inside of the wiring rail 5 from the end portion in the length direction of the wiring rail 5, and penetrates the slit 51 of the wiring rail 5 up and down. At this time, the engaging piece 323 of the mounting portion 32 engages with both edges of the slit 51 of the wiring rail 5 from above.
When the mounting portion 32 is mounted on the wiring rail 5, the connection terminal 324 of the mounting portion 32 is fitted inside each of the two power feeding members 52 and electrically connected.

As shown in FIG. 4, the spotlight 6 includes a housing 61 and a support 62.
The housing 61 has a tubular shape. The color and size of the housing 61 are the same as the color and size of the housing 2 of the sterilizing device 1.
A lens 611 is arranged in the opening of the housing 61. The housing 61 has a built-in light source (not shown) that emits visible light. The visible light emitted by this light source passes through the lens 611 and is irradiated to the outside of the housing 61. The lens 611 aligns the direction of the visible light emitted by the light source with the axial length direction of the housing 61.

The shape, color, and size of the support 62 are the same as the shape, color, and size of the support 3 of the sterilizer 1. The support 62 is attached in the middle of the housing 61.
The support 62 of the spotlight 6 is also attached to the wiring rail 5 in the same manner as the support 3 of the sterilizer 1.

As described above, the sterilizing device 1 and the spotlight 6 are suspended from the wiring rail 5. A plurality of sterilizing devices 1 (or spotlights 6) may be suspended from the wiring rail 5.
The tilt angle of the housing 2 of the sterilizer 1 is adjusted so that, for example, the outlet 2b faces a display fixture (not shown) in a commercial facility. Similarly, the tilt angle of the housing 61 of the spotlight 6 is adjusted so that the lens 611 faces the display fixture.
The power feeding member 52 of the wiring rail 5 is electrically connected to a commercial power source (not shown) to supply power to the sterilizing device 1 and the spotlight 6.
The powered spotlight 6 illuminates a product (not shown) displayed on the display fixture.

In the sterilizer 1, the air supplied from the blower 221 blows air, so that the air sucked from the suction port 2a passes through the inside of the housing 2, is rectified by the rectifying grid 241 and blown out from the outlet 2b.
The fed LED 223 emits light, and the light emitted by the LED 223 irradiates the photocatalyst member 231. As a result, active oxygen is generated around the photocatalyst member 231.
The air flowing inside the housing 2 comes into contact with the photocatalyst member 231 and is sterilized by active oxygen.

Since the plurality of LEDs 223 are arranged in the circumferential direction of the housing 2, the light emitted by the LED 223 (that is, the light that activates the photocatalyst) can be evenly applied to the photocatalyst member 231 in the circumferential direction of the housing 2. Therefore, active oxygen can be effectively generated over the circumferential direction of the housing 2.
Therefore, the sterilizing device 1 can effectively blow out the sterilized air from the housing 2. Since the sterilizing device 1 is directed to the display fixture, the sterilized air can be effectively sent to the periphery of the display fixture.

According to the sterilization device 1 as described above, the sterilization device 1 is attached to the wiring rail 5 at the place where the spotlight 6 is used, so that the sterilization device 1 is as if the spotlight 6 is used. appear. That is, the sterilizing device 1 tends to match the appearance of the installation location.
Since the sterilizing device 1 that easily matches the appearance of the installation location does not give a sense of discomfort to the viewer, it is not necessary to hide the sterilizing device 1. Therefore, since the sterilizing device 1 can be found by searching, it is easy to confirm that the air is sterilized.

The blower 221 and LED 223 are collectively built in the cylinder 22. Therefore, wiring from the commercial power supply to the blower 221 and the LED 223 respectively is easy. Since the tubular body 22 is supported by the support tool 3, the power supply member 11 for supplying power to the blower 221 and the LED 223 can be wired along the support tool 3.

If the photocatalyst member 231 deteriorates over time, the air purification function is lost, so it is necessary to replace the photocatalyst member 231. Further, when an inorganic substance (for example, dust floating in the air) adheres to the photocatalyst member 231, the purifying function of the air is hindered by the adhered substance, so that the photocatalyst member 231 needs to be cleaned regularly.

The photocatalyst member 231 is built in the tubular body 23. Since the cylinders 21 to 24 are connected to each other by screwing screws, it is easy to remove the cylinder 23 from the cylinders 22 and 24. Moreover, when the cylinder 23 is removed, it is not necessary to remove the support 3 from the wiring rail 5, nor is it necessary to remove the cylinder 22 (and the cylinder 21) from the support 3. Therefore, it is easy to replace or clean the photocatalyst member 231.

When the LED 223 is emitting light, visible light is emitted from the translucent body 224 to the outside of the housing 2, so that the translucent body 224 appears to be shining. Whether or not the translucent body 224 appears to be shining indicates whether or not the LED 223 is emitting light, that is, whether or not the air blown from the housing 2 is sterilized. Therefore, the LED 223 inside the housing 2 can be used to indicate whether or not the bacteria are being sterilized on the outside of the housing 2.

Since the translucent body 224 is provided over the entire circumference of the housing 2, light emission / non-light emission can be visually recognized from any position in the circumferential direction of the housing 2.
In addition to the LED 223, a light source that emits visible light may be provided on the outer surface of the housing 2, and this light source may be connected in series with the LED 223. In this case, since the light source on the outer surface of the housing 2 emits light when the LED 223 emits light, it can be known whether or not the LED 223 emits light.

The mounting unit 32 can be easily replaced. Therefore, for example, a mounting portion 32 that is directly fixed to the ceiling 71 (or a wall of a commercial facility) or a mounting portion 32 that can be mounted on a wiring rail having a configuration different from that of the wiring rail 5 is mounted on the support main body 31. The sterilizing device 1 can be mounted at any mounting position.

According to the lighting and sterilization equipment 4 as described above, the spotlight 6 illuminates the product, so that the product can be made to stand out and the purchase motivation of the purchaser can be enhanced. Further, when the sterilizing device 1 sends the sterilized air toward the display fixture, it is possible to provide the purchaser with a sense of security that the air around the display fixture is sterilized.
Since active oxygen also decomposes odorous components, the sterilizing device 1 also functions as a deodorizing device.
In addition, active oxygen also decomposes mold, ethylene gas, etc., which cause deterioration of fresh foods. Therefore, when the product is a fresh food and is sold in a state of being exposed to the outside air, the sterilizing device 1 is particularly useful.

The housing 61 and the support 62 included in the spotlight 6 and the housing 2 and the support 3 included in the sterilizer 1 have the same shape, color, and size. That is, since the appearance shapes of the spotlight 6 and the sterilizing device 1 are similar to each other, there is no sense of discomfort even if the spotlight 6 and the sterilizing device 1 are mixed.

In the sterilizing device 1, the feeding member 11 for feeding power from the wiring rail 5 to the blower 221 and the LED 223 built in the housing 2 can be wired along the support tool 3. Similarly, in the spotlight 6, a power feeding member for supplying power to the light source built in the housing 61 can be wired along the support 62.

The wiring rail 5 is not limited to the configuration suspended from the ceiling 71 of the commercial facility, and may be held by a bracket projecting from the wall of the commercial facility, for example. Alternatively, the wiring rail 5 may be provided in a public facility such as an art museum or a museum, a general house, or the like. In any case, it is easy to add the wiring rail 5 to the existing building. Therefore, the lighting and sterilization equipment 4 can be easily introduced not only in a newly constructed building but also in an existing building.
Further, by adding the sterilizing device 1 to the existing lighting equipment in which the spotlight 6 is attached to the wiring rail 5, the lighting and sterilizing equipment 4 can be easily obtained.

Alternatively, the existing lighting equipment in which a plurality of spotlights 6 are attached to the wiring rail 5 may be changed to the lighting and sterilization equipment 4. In this case, the operator removes a part of the plurality of spotlights 6 from the wiring rail 5. Further, the operator installs the sterilizing device 1 by attaching the support 3 to the wiring rail 5. By replacing at least one spotlight 6 with the sterilizing device 1, the lighting and sterilizing equipment 4 can be easily obtained.
The mounting portion 32 of the support 3 of the sterilizing device 1 and the mounting portion of the support 62 of the spotlight 6 may be shared. In this case, the operator removes the support main body of the support 62 from the mounting portion of the support 62 attached to the wiring rail 5, and the support tool of the sterilizing device 1 is attached to the remaining mounting portion of the support 62. Attach the support main body 31 of 3.

It is desirable that the manufacturer of the sterilizer 1 prepares the sterilizer 1 having a plurality of colors and a plurality of sizes. The operator replaces the spotlight 6 attached to the wiring rail 5 with the sterilizing device 1 having a color and size corresponding to the color and size of the spotlight 6. Here, the size of the housing 2 is, for example, the length and the outer diameter of the housing 2.

In the present embodiment, since the light source member 222 is exposed to the air flowing inside the housing 2, the air flowing inside the housing 2 contributes to the heat dissipation of the LED 223. When the housing 2 is made of metal (for example, made of aluminum), the housing 2 also contributes to heat dissipation of the LED 223.
When the LED 223 emits ultraviolet rays, it is desirable that a protective layer for protecting them from ultraviolet rays is formed on the surface of the blower 221 and the inner peripheral surface of the housing 2. This protective layer may have light reflectivity for reflecting ultraviolet rays. In this case, the reflected ultraviolet rays are also applied to the photocatalyst member 231.
When the LED 223 emits visible light, a reflective layer that reflects visible light may be provided on the inner peripheral surface of the housing 2. In this case, the reflected visible light is also applied to the photocatalyst member 231.

The tilt angle of the housing 2 may be adjustable by remote control. Further, the sterilization device 1 may be configured such that the housing 2 automatically swings or rotates.
A light source that emits visible light may be provided on the inner circumference of the cylinder 24 so as not to obstruct the flow of air blown out from the outlet 2b. In this case, the sterilizer 1 also functions as a spotlight.
The lighting and sterilization equipment 4 is not limited to a configuration in which the sterilization device 1 and the spotlight 6 are attached to the same wiring rail 5. For example, the sterilizing device 1 may be attached to one of the two adjacent wiring rails 5, and the spotlight 6 may be attached to the other.
The sterilizer 1 may be used together with a heat lamp that keeps the product warm.

Embodiment 2.
FIG. 5 is an exploded side view of the sterilization apparatus 1 according to the second embodiment. In FIG. 5, a part of the housing 2 is broken and shown.
The sterilizing device 1 of the present embodiment is substantially the same as the sterilizing device 1 of the first embodiment except for the configuration of the housing 2. Hereinafter, the differences from the first embodiment will be described, and the same components as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

The housing 2 of the present embodiment further includes cylinders 25 to 27.
A female screw similar to the female screw of the cylinder 22 is provided on the inner peripheral surface of one end of each of the cylinders 25 to 27.
On the outer peripheral surface of the other end of each of the cylinders 25 to 27, a male screw similar to the male screw of the cylinder 22 is provided.

A dust collection filter 251 is fixed to the inner peripheral surface of the cylinder 25. The dust collection filter 251 collects dust in the air. The dust collection filter 251 may be a HEPA (High Efficiency Particulate Air) filter or a ULPA (Ultra Low Penetration Air) filter.
The fragrance member 261 is fixed to the inner peripheral surface of the tubular body 26. The fragrance member 261 is configured by, for example, a particulate fragrance being supported on a net. The fragrance member 261 imparts an fragrance component to the air.

An air diaphragm 271 is fixed to the inner peripheral surface of the cylinder 27. The air diaphragm 271 has an iris diaphragm shape, and the opening area can be adjusted manually. In order to make it easier to see the shape of the air throttle 271, only the front view of the air diaphragm 271 is shown in FIG.
The cylinders 21 to 27 can be connected to each other by screwing the male screw and the female screw.

It is desirable that the cylinder 25 is mounted between the cylinders 21 and 22. In this case, the air sucked from the suction port 2a passes through the dust collection filter 251 so that the dust in the air is collected by the dust collection filter 251. Therefore, there is no possibility that dust will be blown out from the sterilizing device 1 together with the air. Further, there is no possibility that dust in the air adheres to the LED 223 or the photocatalyst member 231 and hinders the sterilization of the air.
By adding the tubular body 25 to the housing 2 of the first embodiment, the dust collecting function can be added to the sterilizing device 1.

It is desirable that the cylinder 26 is mounted between the cylinders 23 and 24. Since the fragrance component can be added to the sterilized air, the air to which the fragrance component is added can be blown out from the housing 2.
By adding the tubular body 26 to the housing 2 of the first embodiment, the fragrance diffusion function can be added to the sterilizing device 1.

Similar to the removal of the cylinder 23, the removal of the cylinders 25 and 26 is easy. The cylinder 25 is removed from the housing 2 for replacement or cleaning of the dust collection filter 251. The tubular body 26 is removed from the housing 2 for replacement of the fragrance member 261.

It is desirable that the cylinder 27 is mounted between the cylinders 23 and 24. When both the cylinders 26 and 27 are mounted between the cylinders 23 and 24, it is desirable to mount the cylinder 27 between the cylinders 24 and 26.
When the opening area of the air throttle 271 is small, the air blown out from the housing 2 reaches a long distance without being diffused over a very wide area. When the opening area of the air throttle 271 is large, the air blown out from the housing 2 diffuses over a wide area in the vicinity of the housing 2. That is, by adjusting the opening area of the air throttle 271, the distance that the sterilized air reaches and the range in which the sterilized air diffuses can be changed.

The opening area of the air throttle 271 may be adjustable by remote control.
The air throttle 271 is not limited to the one in which the opening area can be adjusted. Even if the opening area of the air throttle 271 is constant, the distance that the sterilized air can reach and the range in which the sterilized air diffuses can be changed by attaching and detaching the tubular body 27.

The embodiments disclosed this time should be considered to be exemplary in all respects and not restrictive. The scope of the present invention is not intended to include the meaning described above, but is intended to include the meaning equivalent to the scope of claims and all modifications within the scope of claims.
The constituent requirements (technical features) disclosed in each embodiment can be combined with each other, and new technical features can be formed by the combination.
