For example, when the sterilization apparatus is used in a commercial facility (a supermarket, a department store, or the like), it is possible to give a feeling of reassurance to customers that air is sterilized. In the case of the sterilization apparatus described in patent document 1, it is conceivable to suspend the sterilization apparatus from a wall of a commercial facility, a display, or the like.
However, the sterilization apparatus described in patent document 1 includes a rectangular frame body, and may give an uncomfortable feeling to an observer depending on the contents of commercial facilities, the atmosphere, and the like.
However, when the sterilization apparatus is hidden, the guest may misunderstand that the air is not sterilized.
Disclosure of Invention
The invention aims to provide a sterilizing device, an illuminating and sterilizing device and an installation method of the sterilizing device, which are easy to be coordinated with the appearance of an installation place.
The present invention provides a bacteria removing device used in a spot where a spotlight is used, the bacteria removing device including: a cylindrical frame body; a blower configured to blow air sucked into the housing from one opening of the housing out of the other opening of the housing; a photocatalyst member that is in contact with air flowing inside the frame; a light source for irradiating light to the photocatalyst part; and a support member that supports the housing and is attached to an attachment position where the spotlight can be attached, wherein the blower, the photocatalyst member, and the light source are built in the housing.
According to the present invention, the frame body is cylindrical.
Light emitted from the light source is irradiated to the photocatalyst member, and active oxygen is generated around the photocatalyst member.
The air is blown by the blower, and the air sucked from one opening of the housing flows through the inside of the housing. The air flowing inside the housing comes into contact with the photocatalyst member, and bacteria are removed by active oxygen generated around the photocatalyst member. The air after sterilization is blown out from the other opening of the housing.
Since the blower, the photocatalyst mechanism, and the light source are built in the housing, the sterilizing apparatus has a cylindrical shape supported by the support member. Therefore, the appearance of the sterilizing apparatus can be made similar to that of a general spotlight including a cylindrical housing and a holder for the housing.
In a place where a spotlight is used (e.g., a commercial facility), a support member is mounted at a mounting position where the spotlight can be mounted (e.g., a ceiling of the commercial facility or a wiring rail suspended and supported on the ceiling). The sterilizing device then looks like a spotlight. That is, the bacteria removing device is easily compatible with the appearance of the installation site.
Since the sterilization apparatus that is easily compatible with the appearance of the installation place does not give an uncomfortable feeling to the observer, it is not necessary to hide the sterilization apparatus. Therefore, the bacteria removing device can be found by searching, and it is easy to confirm that the air is removed.
In the bacteria removing device of the present invention, the housing includes: a first cylinder supported by the support member and having the blower and the light source built therein; and a second cylinder which is detachably connected to the first cylinder and which contains the photocatalyst member.
According to the present invention, the frame is formed by coupling the second cylinder to the first cylinder.
A blower and a light source are built in the first cylinder. That is, since objects requiring power supply are concentrated in the first cylinder, wiring from the power supply to each of the blower and the light source is facilitated. Since the first cylinder is supported by the support member, a power supply member for supplying power to the blower and the light source may be arranged along the support member.
A photocatalyst member is built in the second cylinder. The second cylinder is detachable from the first cylinder. When the second cylinder is removed, there is no need to remove the first cylinder from the support member or to remove the support member from the mounting position. Therefore, the photocatalyst member can be easily replaced or cleaned.
In the sterilization apparatus according to the present invention, the light source emits visible light or ultraviolet light, and the sterilization apparatus further includes a light transmitting body that transmits the visible light emitted from the light source directly to the outside of the housing, or converts the ultraviolet light emitted from the light source into visible light and transmits the visible light to the outside of the housing.
According to the present invention, the light source emits visible light or ultraviolet light.
When the light source emits visible light, the light-transmitting body allows the visible light emitted from the light source to directly transmit to the outside of the housing. When the light source emits ultraviolet rays, the light-transmitting body converts the ultraviolet rays emitted from the light source into visible light and transmits the visible light to the outside of the housing.
In short, when the light source emits light, the light-transmitting body appears to emit light. Whether the light-transmitting body appears to be emitting indicates whether the light source is emitting light, i.e., whether air blown from the frame is sterilized. Therefore, in order to indicate whether or not bacteria are being removed on the outside of the housing, a light source located on the inside of the housing can be used.
In the sterilization apparatus of the present invention, the plurality of light sources are arranged in a circumferential direction of the housing.
According to the present invention, since the plurality of light sources are arranged in the circumferential direction of the housing, light emitted from the light sources can be irradiated to the photocatalyst member in the circumferential direction of the housing without omission. Therefore, active oxygen can be efficiently generated in the circumferential direction of the frame.
In the sterilization apparatus of the present invention, the support member includes: a support main body attached to the frame; and a mounting portion detachably mounted to the support member main body and mounted at the mounting position.
According to the present invention, the bearing includes a bearing main body and a mounting portion.
The support member main body is mounted to the frame. The mounting portion is detachable from the support member main body.
The mounting portion mounted to the support member main body is mounted at the mounting position. Therefore, by attaching the attachment portion corresponding to the structure of the attachment position to the holder main body, the sterilizing device can be attached to an arbitrary attachment position.
In the bacteria removing device of the present invention, an air throttle is incorporated in the housing at a position downstream of the blower, the photocatalyst member, and the photocatalyst member.
According to the present invention, the housing further incorporates an air throttle. The air throttle is disposed downstream of the blower, the photocatalyst member, and the photocatalyst member.
Since the air flow is throttled by the air throttle, the air after sterilization blown out from the housing does not spread over a wide range and reaches a remote place.
The illumination and sterilization apparatus of the present invention includes: a spotlight having a tubular housing in which a light source for emitting visible light is built, and a support member for supporting the housing; the sterilization apparatus of the present invention; and a wiring rail on which the supports of the spotlight and the sterilizing device are mounted, and which is used for wiring power supply components for supplying power to the spotlight and the sterilizing device.
According to the present invention, both the spotlight and the bacteria removing device of the present invention include a cylindrical housing and a holder for the housing. A wiring track is provided at a place where the spotlight is used, and supports for the spotlight and the sterilizing device are attached to the wiring track. Therefore, the sterilizing apparatus is likely to be contaminated with spot lights in appearance, and is likely to be compatible with the appearance of the installation site.
In the sterilization apparatus, power supply members for supplying power from the wiring rail to the blower and the light source built in the housing can be wired along the support member interposed between the wiring rail and the housing. Similarly, in the spotlight, a power supply member for supplying power to the light source incorporated in the housing can be wired along the support member.
In the illumination and sterilization apparatus of the present invention, the colors of the frame bodies of the spotlight and the sterilization device are the same as each other, and the shapes and the colors of the support members of the spotlight and the sterilization device are the same as each other.
According to the present invention, the housing provided in the spotlight and the housing provided in the sterilizing device are both cylindrical and have the same color.
In addition, the supporting member of the spotlight and the supporting member of the sterilizing device have the same shape and the same color.
That is, since the appearance of the spotlight and the sterilizing apparatus are similar to each other, there is no sense of discomfort even if the spotlight and the sterilizing apparatus are mixed.
The method of installing a bacteria removing device according to the present invention is characterized in that the bacteria removing device includes: a cylindrical frame body; a blower configured to blow air sucked into the housing from one opening of the housing out of the other opening of the housing; a photocatalyst member that is in contact with air flowing inside the frame; a light source for irradiating light to the photocatalyst part; and a support member that supports the housing and is attached to an attachment position where the spotlight can be attached, wherein the blower, the photocatalyst member, and the light source are built in the housing, the sterilizing device is prepared, and the sterilizing device is installed by attaching the support member to the attachment position where the plurality of spotlights are attached, and detaching a part of the plurality of spotlights from the attachment position.
According to the present invention, the lighting and bacteria removing apparatus can be easily obtained by replacing at least one of the spot lights with the bacteria removing device of the present invention at a place where the spot lights are respectively installed at the installation positions.
According to the sterilization apparatus, the illumination and sterilization apparatus, and the method of installing the sterilization apparatus of the present invention, the sterilization apparatus can be easily matched with the appearance of the installation place.

Detailed Description
Hereinafter, embodiments of the present invention will be described.
Embodiment 1.
Fig. 1 is a perspective view of a bacteria removing device according to embodiment 1.
FIG. 2 is a side view of the degerming device.
The illustrated sterilization apparatus 1 includes a housing 2 and a support 3.
The frame 2 is cylindrical.
Hereinafter, one opening of the housing 2 is referred to as an intake port 2a, and the other opening of the housing 2 is referred to as an outlet port 2b.
The frame 2 includes 4 cylindrical bodies 21 to 24.
Fig. 3 is an exploded perspective view of the sterilization apparatus 1. Fig. 3 shows the bacteria removing apparatus 1 with a part cut away.
As shown in fig. 2 and 3, an opening at one end of the cylindrical body 21 is a suction port 2a.
An external thread is provided on the outer peripheral surface of the other end of the cylindrical body 21.
A shield member 211 is fixed to the inner peripheral surface of the cylindrical body 21. The shield member 211 prevents foreign matter (e.g., insects) from entering the inside of the housing 2 through the suction port 2a. The shield member 211 does not obstruct the air flow into the inside of the housing 2. The shield member 211 is, for example, a louver.
A blower 221 and a light source member 222 are fixed to an inner peripheral surface of the cylindrical body 22 (first cylindrical body). The light source member 222 and the blower 221 are adjacent to each other with an appropriate distance therebetween in the axial direction of the cylinder 22.
The blower 221 is a propeller fan and is disposed coaxially with the cylinder 22. The blower 221 blows air from an opening of the drum 22 on the blower 221 side toward an opening of the drum 22 on the light source member 222 side.
The light source unit 222 includes a strip-shaped wiring board and an LED223 (light source) mounted on one surface of the wiring board. The plurality of LEDs 223 are arranged in the longitudinal direction of the light source part 222. Fig. 3 illustrates a case where the LEDs 223 are also arranged in the width direction of the light source part 222. The light source unit 222 extends over the entire circumference of the cylinder 22. The surface on which the LED223 is mounted faces the axis of the cylindrical body 22.
The LED223 emits visible light or ultraviolet light.
An inner peripheral surface of one end of the cylinder 22 on the blower 221 side is provided with a female screw that can be screwed with the male screw of the cylinder 22.
The outer peripheral surface of the other end of the cylindrical body 22 on the light source member 222 side is provided with a male screw similar to the male screw of the cylindrical body 22.
A light-transmitting body 224 (see fig. 1 and 2) is provided on the outer peripheral surface of the cylindrical body 22. The light-transmitting body 224 is formed in a ring shape over the entire circumference of the cylinder 22, and is made of, for example, acrylic resin.
The cylinder 22 is provided with a slit 225 extending in the circumferential direction of the cylinder 22. The plurality of slits 225 are arranged in the circumferential direction of the cylinder 22. The opening of the slit 225 in the outer peripheral surface of the cylinder 22 is closed by the light-transmitting body 224.
A part of the light emitted from the LED223 is incident to the light-transmissive body 224 through the slit 225.
When the LED223 emits visible light, the visible light incident on the light-transmitting body 224 from the inside of the cylindrical body 22 directly passes through the light-transmitting body 224 and is emitted to the outside of the cylindrical body 22.
When the LED223 emits ultraviolet light, for example, a particulate fluorescent material that absorbs ultraviolet light and emits visible light is contained in the light-transmitting body 224. The ultraviolet rays incident on the light-transmitting body 224 from the inside of the cylindrical body 22 are converted into visible light, transmitted through the light-transmitting body 224, and emitted to the outside of the cylindrical body 22.
When the LED223 emits visible light together with ultraviolet light, an optical filter that transmits visible light but does not transmit ultraviolet light may be disposed in each slit 225. In this case, the light-transmitting body 224 does not need to contain the above-described phosphor.
A photocatalyst member 231 is fixed to the inner peripheral surface of the cylindrical body 23 (second cylindrical body). The photocatalyst member 231 has a photocatalyst function and does not obstruct the flow of air. For example, the photocatalyst member 231 includes a cylinder fitted into the cylinder 23 and a mesh covering openings at both ends of the cylinder. The cylinder and the mesh support a photocatalyst in a particulate form, or the cylinder and the mesh are made of a photocatalyst.
The photocatalyst member 231 is activated by receiving visible light or ultraviolet light. The activated photocatalyst member 231 generates active oxygen from oxygen in the air and water. The LED223 emits light for activating the photocatalyst member 231.
An inner peripheral surface of one end of the cylindrical body 23 is provided with a female screw similar to the female screw of the cylindrical body 22.
The outer peripheral surface of the other end of the cylindrical body 23 is provided with a male screw similar to the male screw of the cylindrical body 22.
An inner peripheral surface of one end of the cylindrical body 24 is provided with a female screw similar to the female screw of the cylindrical body 22.
The other end of the cylindrical body 24 opens as the outlet 2b.
A flow straightening grill 241 is fixed to the inner peripheral surface of the cylindrical body 24. The rectifying grill 241 rectifies the flow of the air.
The cylinders 21 and 22 are coupled to each other by screwing male and female screws. Similarly, the cylindrical bodies 22 and 23 (and the cylindrical bodies 23 and 24) are coupled to each other by screwing male and female screws. The tubular bodies 21 to 24 are connected to each other in this order to form the housing 2 (see fig. 1 and 2).
The shield member 211, the blower 221, the light source member 222, the photocatalyst member 231, and the flow straightening grill 241 are arranged in this order from the inlet port 2a toward the outlet port 2b.
As shown in fig. 1 to 3, the support 3 includes a support body 31 and a mounting portion 32.
The support main body 31 includes an arm 311, a fixing member 312, and a pivot shaft 313.
The arm 311 has a straight bar shape. One end portion of the arm 311 is divided into two branches.
The fixing member 312 is held by the fork portion of the arm 311 in such a manner that a part thereof protrudes from the arm 311. The protruding portion of the fixing member 312 protruding from the arm 311 is fixed (e.g., welded) to the cylindrical body 21 of the frame 2.
Further, the cylinder 21 may be provided with the fixing member 312 instead of the support main body 31. In this case, the fixing member 312 is integrally provided to the cylindrical body 21 when the cylindrical body 21 is formed, for example.
The pivot 313 penetrates the fork of the arm 311 and the fixing member 312 perpendicularly to the longitudinal direction of the arm 311. The axial length direction of the pivot shaft 313 is orthogonal to the axial length direction of the housing 2. The holder 312 can swing within a predetermined range around the pivot shaft 313. Since the fixing member 312 is fixed to the cylinder 21, the inclination angle of the frame 2 can be changed around the pivot 313. The tilt angle of the frame 2 is maintained by friction between the fixing member 312 and the arm 311 and the pivot 313, for example.
The mounting portion 32 is cylindrical and includes a threaded 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 direction in opposite directions and coaxially with the mounting portion 32.
As shown in fig. 3, a screw hole 314 is provided along the longitudinal direction of the arm 311 at the other end (end not divided into two parts) of the arm 311. The mounting portion 32 is detachably mounted to the support main body 31 by screwing the threaded portion 321 into the threaded hole 314 of the arm 311.
As shown in fig. 2, an engaging piece 323 is provided on the circumferential surface of the proximal end portion of the mounting shaft 322, and a connection terminal 324 is provided on the circumferential surface of the distal end portion of the mounting shaft 322. The engaging piece 323 and the connection terminal 324 are each in the shape of a flange.
The connection terminal 324, the blower 221, and the light source member 222 are electrically connected to each other via the metal power supply member 11. The power supply member 11 is wired along the support 3. The power supply member 11 disposed on the mounting portion 32 and the power supply member 11 disposed on the support main body 31 are electrically connected by screwing the screw portion 321 into the screw hole 314.
Fig. 4 is a perspective view of the illumination and sterilization apparatus.
The illumination and sterilization apparatus 4 in the figure includes a sterilization device 1, a wiring rail 5 (mounting position), and a spotlight 6.
As shown in fig. 2 and 4, the wiring rail 5 has a square tubular shape and is suspended and supported on a ceiling 71 of a commercial facility.
A string-like hanger 72 is hung from the ceiling 71. The plurality of suspending members 72 are arranged in one direction. The wiring rail 5 is held at the lower end of each hanger 72 so as to extend parallel to the ground of a commercial facility, not shown.
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 supply members 52 are arranged on the inner side of the wiring track 5 over the entire length. One power supply member 52 is along one side surface of the wiring rail 5, and the other power supply member 52 is along the other side surface of the wiring rail 5. Each power feeding member 52 has a U-shaped cross section. The respective U-shaped openings of the two power supply members 52 face each other.
The mounting portion 32 of the support 3 of the sterilizing apparatus 1 is detachably mounted on the wiring rail 5. For example, the attachment shaft 322 of the attachment portion 32 is inserted into the wiring rail 5 from the end portion in the longitudinal direction of the wiring rail 5, and vertically penetrates through the slit 51 of the wiring rail 5. At this time, the engaging pieces 323 of the mounting portion 32 engage with both edge portions of the slit 51 of the wiring rail 5 from above.
When the attachment portion 32 is attached to the wiring rail 5, the connection terminal 324 of the attachment portion 32 is fitted into each of the two power supply members 52 and electrically connected to the power supply member 52.
As shown in fig. 4, the spotlight 6 includes a frame 61 and a holder 62.
The frame 61 is cylindrical. The color and size of the frame 61 are the same as those of the frame 2 of the sterilizing apparatus 1.
A lens 611 is provided in the opening of the frame 61. The housing 61 incorporates a light source (not shown) that emits visible light. The visible light emitted from the light source is transmitted through the lens 611 to be irradiated to the outside of the housing 61. The lens 611 aligns the direction of the visible light emitted from 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 those of the support 3 of the sterilizing apparatus 1. The support 62 is mounted to the middle of the frame 61.
The support 62 of the spotlight 6 is also attached to the wiring rail 5, as is the case with the support 3 of the sterilizing apparatus 1.
As described above, the sterilizing device 1 and the spotlight 6 are suspended on the wiring track 5. Further, a plurality of sterilizing devices 1 (or spotlights 6) may be suspended on the wiring rail 5.
The inclination angle of the housing 2 of the sterilization apparatus 1 is adjusted so that the air outlet 2b faces a display tool, not shown, in a commercial facility, for example. Similarly, the inclination angle of the frame 61 of the spotlight 6 is adjusted so that the lens 611 faces the display device.
The power supply member 52 of the wiring rail 5 is electrically connected to a commercial power supply, not shown, to supply power to the sterilizing apparatus 1 and the spotlight 6.
The powered spotlight 6 illuminates the not-shown merchandise items displayed on the display device.
In the sterilization apparatus 1, air is blown by the blower 221 to which power is supplied, and the air sucked from the suction port 2a flows inside the housing 2, is rectified by the rectifying grill 241, and is blown out from the blow port 2b.
The LED223 to which power is supplied emits light, and the light emitted from the LED223 is irradiated to the photocatalyst member 231. As a result, active oxygen is generated around the photocatalyst member 231.
The air flowing inside the housing 2 contacts 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 from the LEDs 223 (i.e., the light for activating the photocatalyst) can be irradiated to the photocatalyst member 231 without omission in the circumferential direction of the housing 2. Therefore, active oxygen can be efficiently generated in the circumferential direction of the frame 2.
Therefore, the sterilization apparatus 1 can efficiently blow out the sterilized air from the housing 2. Since the sterilizer 1 is directed to the display device, the sterilized air can be efficiently sent to the periphery of the display device.
According to the above-described sterilization apparatus 1, the sterilization apparatus 1 is mounted on the wiring rail 5 at a place where the spotlight 6 is used, so that the sterilization apparatus 1 looks like the spotlight 6. That is, the sterilization apparatus 1 is easily compatible with the appearance of the installation site.
Since the bacteria removing device 1 which is easily compatible with the appearance of the installation place does not give a sense of discomfort to the observer, it is not necessary to hide the bacteria removing device 1. Therefore, the bacteria removing device 1 is found when the user looks for it, and thus it is easy to confirm that the air is removed.
The blower 221 and the LED223 are integrally built in the barrel 22. Therefore, wiring from the commercial power supply to the blower 221 and the LED223, respectively, becomes easy. Since the cylindrical body 22 is supported by the support 3, the power supply member 11 for supplying power to the blower 221 and the LED223 can be wired along the support 3.
When the photocatalyst member 231 deteriorates with time, the photocatalyst member 231 needs to be replaced because the air purification function is lost. In addition, when inorganic substances (for example, dust floating in the air) adhere to the photocatalyst member 231, the photocatalyst member 231 needs to be periodically cleaned because the adhering substances inhibit the air purification function.
The photocatalyst member 231 is built in the cylinder 23. Since the cylindrical bodies 21 to 24 are coupled to each other by screwing screws, the cylindrical body 23 can be easily detached from the cylindrical bodies 22 and 24. In addition, when the cylinder 23 is detached, neither the support 3 nor the cylinder 22 (and the cylinder 21) from the support 3 need to be detached from the wiring rail 5. Therefore, the photocatalyst member 231 can be easily replaced or cleaned.
When the LED223 emits light, visible light is emitted from the light-transmitting body 224 to the outside of the housing 2, and therefore the light-transmitting body 224 appears to emit light. Whether or not the light-transmitting body 224 appears to be emitting indicates whether or not the LED223 is emitting light, that is, whether or not the air blown out from the frame body 2 is sterilized. Therefore, the LED223 positioned inside the housing 2 can be used to indicate whether or not bacteria are being removed on the outside of the housing 2.
Since the light-transmitting body 224 is provided over the entire circumference of the housing 2, light emission/non-light emission can be visually confirmed from any position in the circumferential direction of the housing 2.
Alternatively, a light source that emits visible light may be provided on the outer surface of the housing 2 separately from the LED223, and the light source may be connected in series to the LED223. In this case, since the light source on the outer surface of the housing 2 emits light when the LED223 emits light, it is known whether or not the LED223 emits light.
The mounting portion 32 can be easily replaced. Therefore, the sterilizing apparatus 1 can be mounted at an arbitrary mounting position by mounting the mounting portion 32 directly fixed to, for example, the ceiling 71 (or a wall of a commercial facility) or the mounting portion 32 that can be mounted to a wiring rail constituting a different structure from the wiring rail 5 to the support main body 31.
According to the above illumination and sterilization apparatus 4, the commodity is illuminated by the spotlight 6, and the commodity can be made conspicuous, thereby enhancing the purchase desire of the purchaser. Further, the air having been sterilized is sent toward the display device by the sterilizing device 1, and the purchaser can be provided with a feeling of reassurance that the air around the display device is sterilized.
Since active oxygen also decomposes odor components, the sterilizer 1 also functions as a deodorizing device.
In addition, active oxygen also decomposes mold, ethylene gas, and the like, which are causes of deterioration of fresh foods. Therefore, the sterilization apparatus 1 is particularly useful in the case where the commercial product is fresh food and sold in a state of being exposed to the outside air.
The frame 61 and the holder 62 provided in the spotlight 6 and the frame 2 and the holder 3 provided in the sterilizer 1 have the same shape, color, and size. That is, since the spot light 6 and the bacteria removing device 1 have similar external shapes, there is no uncomfortable feeling even if the spot light 6 and the bacteria removing device 1 are mixed.
In the sterilizing apparatus 1, the power supply member 11 for supplying power from the wiring rail 5 to the blower 221 and the LED223 built in the housing 2 can be wired along the support 3. Similarly, in the spotlight 6, a power supply member for supplying power to the light source inwardly placed in the frame 61 can be wired along the support 62.
The wiring rail 5 is not limited to a structure suspended from the ceiling 71 of the commercial facility, and may be, for example, a structure held by a bracket protruding from a wall of the commercial facility. Alternatively, the wiring track 5 may be installed in a public facility such as an art gallery or a museum, a general house, or the like. In any case, the wiring track 5 can be easily added to an existing building. Therefore, the illumination and sterilization apparatus 4 can be easily introduced not only into a newly constructed building but also into an existing building.
Further, the lighting and sterilizing device 4 can be easily obtained by adding the sterilizing device 1 to the existing lighting device in which the spotlight 6 is attached to the wiring rail 5.
Alternatively, an existing lighting apparatus in which a plurality of spot lamps 6 are attached to the wiring track 5 may be changed to the lighting and sterilizing apparatus 4. In this case, the operator removes a part of the plurality of spotlights 6 from the wiring rail 5. Further, the worker mounts the carrier 3 on the wiring rail 5 to install the sterilizing apparatus 1. By replacing at least one spot light 6 with the sterilizing apparatus 1, the illumination and sterilization apparatus 4 can be easily obtained.
The mounting portion 32 of the support 3 of the sterilizing device 1 can be common to the mounting portion of the support 62 of the spotlight 6. In this case, the operator removes the support body of the support 62 from the mounting portion of the support 62 mounted on the wiring rail 5, and mounts the support body 31 of the support 3 of the sterilizing device 1 on the mounting portion of the remaining support 62.
Preferably, the manufacturer of the sterilization apparatus 1 prepares the sterilization apparatus 1 in a variety of colors and in a variety of sizes. The worker 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 dimensions of the frame body 2 are, for example, the length and the outer diameter of the frame body 2.
In the present embodiment, since the light source unit 222 is exposed to the air flowing inside the housing 2, the air flowing inside the housing 2 contributes to heat dissipation of the LED223. When the housing 2 is made of metal (for example, aluminum), the housing 2 also contributes to heat dissipation of the LED223.
When the LED223 emits ultraviolet rays, a protective layer for protecting the surface of the blower 221 and the inner circumferential surface of the housing 2 from ultraviolet rays is preferably formed on these surfaces. The protective layer may have light reflectivity for reflecting ultraviolet rays. In this case, the reflected ultraviolet rays are also irradiated to the photocatalyst member 231.
When the LED223 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 irradiated to the photocatalyst member 231.
The tilt angle of the frame 2 can be adjusted by remote operation. The sterilizing apparatus 1 may be configured such that the housing 2 automatically swings or rotates.
The light source that emits visible light may be provided on the inner periphery of the cylindrical body 24 so as not to obstruct the flow of air blown out from the outlet port 2b. In this case, the sterilization device 1 also functions as a spotlight.
The illumination and sterilization apparatus 4 is not limited to the configuration in which the sterilization device 1 and the spotlight 6 are mounted on 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 sterilization apparatus 1 may be used together with a heat lamp for keeping the temperature of the commercial product.
Embodiment 2.
Fig. 5 is an exploded side view of the bacteria removing device 1 according to embodiment 2. Fig. 5 shows a part of the housing 2 in a cutaway view.
The sterilization apparatus 1 of the present embodiment is substantially the same as the sterilization apparatus 1 of embodiment 1 except for the configuration of the housing 2. Hereinafter, differences from embodiment 1 will be described, and the same components as those in embodiment 1 will be denoted by the same reference numerals and their description will be omitted.
The housing 2 of the present embodiment further includes the cylindrical bodies 25 to 27.
The inner peripheral surfaces of one ends of the tubular bodies 25 to 27 are provided with female screws similar to those of the tubular body 22.
The outer peripheral surfaces of the other ends of the cylindrical bodies 25 to 27 are provided with male screws similar to those of the cylindrical body 22.
A dust collecting filter 251 is fixed to the inner peripheral surface of the cylindrical body 25. The dust collecting filter 251 captures dust in the air. The dust collecting filter 251 may also be a HEPA (High Efficiency Particulate Air) filter or an ULPA (Ultra Low polishing Air) filter.
A fragrance member 261 is fixed to the inner peripheral surface of the cylindrical body 26. The fragrance member 261 is configured by, for example, loading a particulate fragrance on a web. The fragrance member 261 imparts a fragrance component to the air.
An air throttle 271 is fixed to the inner peripheral surface of the cylinder 27. The air throttle 271 is in the form of an iris adjuster, and the opening area can be manually adjusted. In order to easily observe the shape of the air throttle 271, only a front view of the air throttle 271 is shown in fig. 5.
The cylinders 21 to 27 can be coupled to each other by screwing the male screw and the female screw.
Preferably, the cylinder 25 is mounted between the cylinders 21, 22. In this case, the air sucked from the suction port 2a passes through the dust collection filter 251, and thereby the dust in the air is collected by the dust collection filter 251. Therefore, there is no fear that dust is blown out from the sterilizing apparatus 1 together with air. Further, there is no fear that dust in the air adheres to the LED223 or the photocatalyst member 231 to hinder the sterilization of the air.
By adding the cylindrical body 25 to the housing 2 of embodiment 1, a dust collecting function can be added to the sterilizing apparatus 1.
Preferably, the cylinder 26 is mounted between the cylinders 23, 24. Since the air after sterilization can be imparted with the aromatic component, the air to which the aromatic component is imparted can be blown out from the housing 2.
By adding the cylindrical body 26 to the housing 2 of embodiment 1, the fragrance diffusing function can be added to the sterilizing device 1.
Similarly to the removal of the cylindrical body 23, the respective removal of the cylindrical bodies 25 and 26 is easy. The cylinder 25 is detached from the housing 2 for replacement or cleaning of the dust collection filter 251. To replace the fragrance member 261, the cartridge 26 is detached from the housing 2.
Preferably, the cylinder 27 is installed between the cylinders 23 and 24. When both the cylindrical bodies 26 and 27 are mounted between the cylindrical bodies 23 and 24, the cylindrical body 27 is preferably mounted between the cylindrical bodies 24 and 26.
When the opening area of the air throttle 271 is small, the air blown out from the frame 2 does not spread over a wide range and reaches a distant place. When the opening area of the air throttle 271 is large, the air blown out from the frame 2 spreads widely in the vicinity of the frame 2. That is, by adjusting the opening area of the air throttle 271, the distance that the sterilized air reaches and the range over which the sterilized air spreads can be changed.
In addition, the opening area of the air throttle 271 can be adjusted by remote operation.
The air throttle 271 is not limited to the structure in which the opening area can be adjusted. Even if the opening area of the air throttle 271 is constant, the distance the sterilized air reaches and the range over which the sterilized air spreads can be changed by attaching and detaching the cylinder 27.
It is needless to say that the embodiments disclosed herein are illustrative in all respects, and not restrictive. The scope of the present invention is not limited to the above-described meanings, but is intended to include meanings equivalent to the claims and all modifications within the scope.
The constituent elements (technical features) disclosed in the respective embodiments may be combined with each other, and new technical features may be formed by the combination.
