Description

[Technical field]

[0001] The present disclosure relates to a facility having an insect-proofing function. [Background technology]

[0002] In facilities with clean rooms, such as parts factories, food factories, and medical facilities, where contamination by foreign matter is a problem, it is important to take insect control measures to prevent insects from entering. From the perspective of insect control measures that are friendly to the natural ecosystem, it is necessary to realize facilities that do not attract insects, rather than just exterminating them with insecticides, etc. For example, Patent No. 7040845 discloses a system that uses a low-insect-attracting or insect-repelling light source and an insect-attracting light source to prevent insects from entering a building. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7040845 Summary of the Invention [Problem to be solved by the invention]

[0004] Furthermore, there is a demand for facilities with improved insect intrusion prevention capabilities.

[0005] The present inventors have an intention to provide a facility with improved insect intrusion prevention function. [Means for solving the problem]

[0006] According to one embodiment, the facility includes a building having an entrance, a UV-absorbing member constituting the entire or part of the entrance, and an UV generator for irradiating the member with UV rays. The building is airtight against insects when the entrance is closed.

[0007] A facility in another embodiment includes a building having an entrance / exit, an openable / closable first partition covering the entrance, an openable / closable second partition located inside the building relative to the first partition and defining a first space between the first partition and the second partition, and a pressurizer that puts the first space under positive pressure relative to the outside. Effect of the Invention

[0008] The inventors analyzed the ways in which insects enter facilities and found that the main routes are entrances and exits through which people and objects enter and exit, and gaps connecting the outside and inside of the facility.

[0009] In one embodiment, the entire or part of the entrance is made of a material having ultraviolet absorbing properties, and an ultraviolet generator irradiates this material with ultraviolet rays. Since ultraviolet rays are attractive to insects, insects near the entrance are attracted to the ultraviolet generator. This prevents insects from entering through the entrance. Furthermore, the building of this facility is airtight against insects when the entrance is closed. This building prevents insects from entering through gaps other than the entrance.

[0010] In another embodiment, the facility includes a first partition covering an entrance to a building, a second partition forming a first space between the first partition and the second partition, and a pressurizer that puts the first space under positive pressure relative to the outside. Because the first space is under positive pressure, when the first partition is opened, for example, to bring in cargo or to allow people to enter or exit, the air in the first space flows outward. Even if there are insects near the first partition, the insects are prevented from entering the first space. This prevents insects from entering through the entrance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, the present invention will be described in detail based on preferred embodiments with reference to the drawings as appropriate.

[0013] FIG. 1 is a schematic diagram showing a facility 2 according to an embodiment. The facility 2 includes a building 4, an ultraviolet generator 6, and an ultraviolet absorbing member 8 (ultraviolet absorber 8). FIG. 2 is a schematic diagram showing the facility 2 of FIG. 1 from above. In this figure, the internal structure of the facility 2 is shown. The facility 2 further includes a clean room 10, an inner ultraviolet generator 12, an inner member 14 (inner ultraviolet absorber 14) having ultraviolet absorbing properties, an outside air intake 16, and an interior light 18. In this embodiment, the facility 2 is an industrial product factory. The facility 2 does not have to be an industrial product factory. The facility 2 may be any facility 2 where prevention of insect intrusion is required, such as a food factory or a medical facility.

[0014] The building 4 is provided with an entrance 20. Workers, equipment, cargo, etc. enter and exit through the entrance 20. In Figs. 1 and 2, one entrance 20 is shown, but multiple entrances 20 may be provided. In this embodiment, the building 4 is provided with multiple windows 22. The windows 22 are normally closed. An interior light 18 is provided inside the building 4. LED lighting is used as the interior light 18.

[0015] When the entrance 20 is closed, the building 4 is airtight against insects. Specifically, when the entrance 20 is closed, all gaps connecting the outside and inside of the building 4, such as gaps at the entrance 20, gaps at the windows 22, and gaps between the pipes and the walls of the building 4, are sealed and do not exist, or even if they do exist, their width is suppressed to 0.4 mm or less. Alternatively, gaps with a width greater than 0.4 mm are covered with a net with a mesh width of 0.4 mm or less, so that the width of the gap is substantially 0.4 mm or less.

[0016] FIG. 3(a) shows an example of a net 24 that is placed over a gap with a width of more than 0.4 mm, and FIG. 3(b) shows an enlarged portion of FIG. 3(a). In this embodiment, the mesh is square. In FIG. 3(b), the symbol W represents the width of the mesh of the net 24. As shown in the figure, the width W of the mesh is defined as the width of the gap between adjacent warp threads 26 of the net 24 or the width of the gap between weft threads 28. When the mesh is rectangular, that is, when the width of the gap between the warp threads 26 is different from the width of the gap between the weft threads 28, the larger of these widths is defined as the width W of the mesh. As described above, the width W is 0.4 mm or less. The shape of the mesh may be hexagonal. In this net, the shape is a hexagonal mesh. In this case, the width W of the mesh is defined as the largest distance between the opposing sides. The mesh may be shaped in other polygonal shapes. The net may have a plurality of types of meshes with different sizes. In this case, the width W is measured relative to the largest mesh.

[0017] In Fig. 3, the mesh is arranged in a checkerboard pattern, but the arrangement of the mesh is not limited to this. For example, in a structure in which vertical rows of mesh are arranged horizontally, the mesh positions between adjacent vertical rows may be shifted vertically in a "zigzag" arrangement.

[0018] The ultraviolet absorbing body 8 constitutes the whole or a part of the entrance / exit 20. In this embodiment, the ultraviolet absorbing body 8 is a sheet shutter having ultraviolet absorbing properties. This sheet shutter covers the whole opening of the entrance / exit 20. When the sheet shutter is closed, the entrance / exit 20 is closed.

[0019] A film having ultraviolet absorbing properties that covers the whole or part of the entrance 20 may be used as the ultraviolet absorbing body 8. For example, a film having ultraviolet absorbing properties may be attached to the front surface of a door or shutter provided at the entrance 20. A curtain having ultraviolet absorbing properties may be used as the ultraviolet absorbing body 8. A curtain having ultraviolet absorbing properties may be hung on the front surface of a door or shutter provided at the entrance 20.

[0020] In this specification, "ultraviolet rays" refers to light having a wavelength of 330 nm or more and 370 nm or less. "Ultraviolet ray absorbing member" refers to a member having an ultraviolet ray absorption rate of 90% or more.

[0021] The ultraviolet generator 6 is located outside the building 4. The ultraviolet generator 6 irradiates ultraviolet rays toward the ultraviolet absorber 8 from a position away from the building 4. The ultraviolet rays emitted from the ultraviolet generator 6 have directionality. The output intensity of the ultraviolet generator 6 is variable. In FIG. 2, the symbol L represents the distance between the ultraviolet generator 6 and the ultraviolet absorber 8. In this embodiment, the distance L is set to 4 m or more and 30 m or less. In this embodiment, the ultraviolet generator 6 irradiates the entire ultraviolet absorber 8. The ultraviolet generator 6 does not have to irradiate the entire ultraviolet absorber 8. The ultraviolet generator 6 may irradiate a part of the ultraviolet absorber 8.

[0022] The clean room 10 is located inside the building 4. The clean room 10 is a room in the facility 2 that requires particularly strict cleanliness. The clean room 10 has stricter control standards for not only insects but also dirt and airborne dust than other rooms. In this embodiment, the cleanliness of the clean room 10 is Class 1000 according to the US Federal Standard Fed.Std.209E. That is, in this clean room 10, the number of foreign matter particles of 0.5 μm or more per cubic foot is 1000 or less. The clean room 10 has an entrance / exit 20. Although not shown, an air shower room is provided inside the entrance / exit 20 of the clean room 10.

[0023] The inner ultraviolet absorber 14 constitutes the whole or part of the entrance 30 of the clean room 10. In this embodiment, the inner ultraviolet absorber 14 is an ultraviolet absorbing film attached to the front of the door of the entrance 30. This film covers the entire door. A UV absorbing curtain may be used as the inner ultraviolet absorber 14. A UV absorbing curtain may be hung on the front of the door provided at the entrance 30 of the clean room 10.

[0024] The inner ultraviolet ray generator 12 is located inside the building 4 and outside the clean room 10. The inner ultraviolet ray generator 12 irradiates ultraviolet rays toward the inner ultraviolet ray absorber 14 from a position away from the clean room 10. In this embodiment, the inner ultraviolet ray generator 12 irradiates the entire inner ultraviolet ray absorber 14. The inner ultraviolet ray generator 12 does not have to irradiate the entire inner ultraviolet ray absorber 14. The inner ultraviolet ray generator 12 may irradiate a part of the inner ultraviolet ray absorber 14.

[0025] The facility 2 does not necessarily have to have the clean room 10. The entire building 4 may be the clean room 10.

[0026] The outside air intake 16 is attached to the building 4. The building 4 is provided with a plurality of outside air intakes 16. Each outside air intake 16 connects the inside and outside of the building 4. In this embodiment, the outside air intake 16 has a tubular shape with a circular opening. The opening of the outside air intake 16 may be rectangular or another polygonal shape. FIG. 4 is a front view of the outside air intake 16. As shown in FIG. 4, the outside air intake 16 is covered with a net 32. The mesh width W of this net 32 ​​is 0.4 mm or less.

[0027] The effects of this embodiment will be described below.

[0028] In this embodiment, the entire or part of the entrance / exit 20 is made of an ultraviolet absorbing body 8, and the ultraviolet absorbing body 8 is irradiated with ultraviolet rays by the ultraviolet absorbing body 6. Ultraviolet rays are attractive to insects. Because the ultraviolet absorbing body 8 absorbs ultraviolet rays, reflection of ultraviolet rays at the ultraviolet absorbing body 8 is suppressed. Because reflected light from the ultraviolet absorbing body 8 constituting the entrance / exit 20 is suppressed, insects approaching the entrance / exit 20 are not attracted in the direction of the entrance / exit 20. Insects approaching the entrance / exit 20 are attracted in the direction of the ultraviolet absorbing body 6. This prevents insects from entering through the entrance / exit 20.

[0029] It is preferable that the ultraviolet absorbing body 8 constitutes the entire front surface of the entrance / exit 20. In this way, it is possible to prevent insects from being attracted to the entire surface of the entrance / exit 20.

[0030] A sheet shutter having ultraviolet absorbing properties is preferable as the ultraviolet absorbing body 8. The sheet shutter can be used as a door for the entrance / exit 20. No special materials are required to realize the ultraviolet absorbing body 8. By using the sheet shutter, the ultraviolet absorbing body 8 can be easily realized.

[0031] A film having ultraviolet absorbing properties may be used as the ultraviolet absorbing body 8. The film can be attached to an existing entrance 20 constituted by a door or the like. By using the film, an entrance 20 that is insect-proof can be realized by utilizing an existing structure.

[0032] It is preferable that the ultraviolet ray generator 6 irradiates ultraviolet rays onto the entire front surface of the entrance / exit 20. In this way, insects approaching the entrance / exit 20 can be effectively attracted to the ultraviolet ray generator 6 side.

[0033] It is preferable that the ultraviolet ray generator 6 does not radiate ultraviolet rays to areas around the entrance 20 other than the entrance 20. In this manner, insects that are not in the vicinity of the entrance 20 are effectively prevented from being attracted to the entrance 20 side.

[0034] The distance L between the ultraviolet ray generator 6 and the ultraviolet ray absorber 8 is preferably 10 m or more. By setting the distance L to 10 m or more, insects attracted by the ultraviolet ray generator 6 are prevented from approaching the entrance / exit 20.

[0035] It is preferable that the intensity of the ultraviolet light emitted by the ultraviolet light generator 6 is variable. The environment in which the ultraviolet light generator 6 is installed differs depending on the facility. The feasible distance between the ultraviolet light generator 6 and the ultraviolet light absorber 8 also differs depending on the facility. By making the intensity of the ultraviolet light emitted by the ultraviolet light generator 6 variable, it is possible to select the intensity of the ultraviolet light according to the distance between the ultraviolet light generator 6 and the ultraviolet light absorber 8. This makes it possible to effectively attract insects near the entrance / exit 20 to the ultraviolet light generator 6 while suppressing the output of the ultraviolet light generator 6.

[0036] In this embodiment, the entirety or part of the entrance / exit 30 of the clean room 10 is formed of the inner ultraviolet absorber 14, and the inner ultraviolet generator 12 irradiates the inner ultraviolet absorber 14 with ultraviolet rays. Insects approaching the vicinity of the entrance / exit 30 of the clean room 10 are attracted toward the inner ultraviolet generator 12 without being attracted toward the entrance / exit 30. As described above, in this embodiment, insects are prevented from entering the building 4, but even if an insect does enter, the insect is effectively prevented from entering the clean room 10 through the entrance / exit 30 of the clean room 10.

[0037] The distance between the inner ultraviolet ray generator 12 and the inner ultraviolet ray absorber 14 is preferably 10 m or more. By setting this distance to 10 m or more, insects attracted to the inner ultraviolet ray generator 12 are prevented from approaching the entrance / exit 30 of the clean room 10.

[0038] In this embodiment, the building 4 is airtight against insects when the entrance 20 is closed. Specifically, the building 4 does not have any gaps connecting the inside and outside, or even if it has a gap, the width of the gap is 0.4 mm or less. For example, all the gaps of the windows 22, the gaps between the pipes and the walls of the building 4, etc. are filled, or even if a gap exists, the width is 0.4 mm or less, or a net 24 with a mesh size of 0.4 mm or less is placed over a gap with a width larger than 0.4 mm, so that the gap width is substantially 0.4 mm or less. This prevents insects from entering the building 4 from the outside.

[0039] From the viewpoint of effectively preventing the intrusion of insects, the width of the gap is more preferably 0.3 mm or less, and further preferably 0.2 mm or less.

[0040] In this embodiment, the outside air intake 16 provided in the building 4 is covered with a net 32. The mesh width W of this net 32 ​​is 0.4 mm or less. This net 32 ​​prevents insects from entering from the outside. From the viewpoint of effectively preventing insects from entering, the mesh width W is more preferably 0.3 mm or less, and further preferably 0.2 mm or less. From the viewpoint of effectively taking in outside air, the mesh width W is preferably 0.15 mm or more.

[0041] In this embodiment, the interior lights 18 in the building 4 are LED lights. LED lights generally have fewer wavelengths of light that attract insects compared to incandescent lights. For example, LED lights contain less ultraviolet light than incandescent lights. By using LED lights as the interior lights 18, it is possible to prevent insects from being attracted by light leaking from the interior to the outside when the doorway 20 is open, for example.

[0042] 5 is a schematic diagram showing the internal structure of a facility 40 according to another embodiment. The facility 40 includes a building 42, an ultraviolet generator 44, an ultraviolet absorber 46, a clean room 48, a first inner ultraviolet generator 50, a second inner ultraviolet generator 52, an outside air intake 54, and an interior light 56. The facility 40 does not include an inner ultraviolet absorber. The facility 40 is the same as the facility 2 in FIG. 1 except that it does not include an inner ultraviolet absorber and that it includes the first inner ultraviolet generator 50 and the second inner ultraviolet generator 52.

[0043] The first inner ultraviolet generator 50 is located inside the building 42 and outside the clean room 48. The first inner ultraviolet generator 50 is provided at a position where it can irradiate as wide an area as possible inside the building 42. The second inner ultraviolet generator 52 is located inside the clean room 48. The second inner ultraviolet generator 52 is provided at a position where it can irradiate as wide an area as possible inside the clean room 48.

[0044] In this embodiment, a first inner ultraviolet ray generator 50 is provided outside the clean room 48 inside the building 42. Even if insects invade the building 42, the first inner ultraviolet ray generator 50 attracts the insects. By capturing the insects, the insects are effectively prevented from invading the clean room 48. Furthermore, since the first inner ultraviolet ray generator 50 attracts the insects inside the building 42, it also functions as a monitoring device for determining whether insects have invaded the building 42 and how many insects have invaded.

[0045] In this embodiment, a second inner ultraviolet ray generator 52 is provided in the clean room 48. Even if insects invade the clean room 48, the second inner ultraviolet ray generator 52 attracts the insects. By capturing the insects, the insects in the clean room 48 can be removed. The second inner ultraviolet ray generator 52 also functions as a monitoring device for whether insects have invaded the clean room 48 and how many insects have invaded.

[0046] FIG. 6 is a schematic diagram showing a facility 60 according to another embodiment. This figure shows the facility 60 from above. In this figure, the internal structure of the facility 60 is shown. This facility 60 includes a building 62, a clean room 64, and an outside air intake 66. The clean room 64 and the outside air intake 66 are the same as those in the facility 2 in FIG. 1. In this embodiment, this facility 60 is an industrial product factory. The facility 60 does not have to be an industrial product factory. The facility 60 may be any facility 60 where prevention of insect intrusion is required, such as a food factory or a medical facility.

[0047] The building 62 is provided with an entrance / exit 68. Workers, equipment, cargo, etc. enter and exit through the entrance / exit 68. In FIG. 1, one entrance / exit 68 is shown, but multiple entrances / exits 68 may be provided. FIG. 7 is an enlarged view of the vicinity of the entrance / exit 68. As shown in FIG. 7, the facility 60 further includes a first partition 70, a second partition 72, a third partition 74, and a pressurizer 76. The first partition 70, the second partition 72, the third partition 74, and the pressurizer 76 provide an insect-proofing function.

[0048] The first partition 70 covers the entrance / exit 68. In this embodiment, the first partition 70 covers the entrance / exit 68 together with the pressurizer 76. The first partition 70 can be opened and closed. The outer surface of the first partition 70 faces the outside of the facility 60. The outer surface of the first partition 70 is exposed to the outside. In this embodiment, the first partition 70 has light-blocking properties. In this embodiment, the first partition 70 is a curtain. The first partition 70 may be a door or a shutter. The first partition 70 may be another member.

[0049] The second partition 72 is located inside the building 62 relative to the first partition 70. The second partition 72 can be opened and closed. The second partition 72, together with the first partition 70, the walls, the ceiling, etc., configures a closed first space 78. In this embodiment, the second partition 72 is a shutter. The second partition 72 may be a door or a curtain. The second partition 72 may be another member.

[0050] The third partition 74 is located inside the building 62 relative to the second partition 72. The third partition 74 can be opened and closed. The third partition 74, together with the second partition 72, the walls, the ceiling, and the like, constitutes a closed second space 80. The inside of the third partition 74 is the "interior" of the building 62, where various facilities such as the clean room 64 are present. In this embodiment, the third partition 74 is a shutter. The third partition 74 may be a door or a curtain. The third partition 74 may be another member. As shown in FIG. 7, in this embodiment, the volume of the second space 80 is larger than the volume of the first space 78.

[0051] The pressurizer 76 is located in the first space 78. The pressurizer 76 makes the pressure in the first space 78 positive with respect to the outside. In this embodiment, the pressurizer 76 is an air jet that blows air into the first space 78. In this embodiment, as shown in Fig. 7, air is jetted from both ends of the first space 78 toward the center. The pressurizer 76 does not have to be an air jet.

[0052] In this facility 60, the first partition 70, the second partition 72, and the third partition 74 are usually closed to prevent insects and the like from entering the building 62. The typical steps for carrying cargo and the like from the outside into the building 62 are as follows. The same applies when a person enters the building. (a) The pressurizer 76 is operated to create a positive pressure in the first space 78. (b) The first partition 70 is opened. (c) Open the second partition 72 and move the cargo to the second space 80. (d) The first partition 70 and the second partition 72 are closed and the pressurizer 76 is stopped. (e) Open the third partition 74 and move the cargo to the inside of the building 62. (f) Close the third partition 74.

[0053] In the above, the pressurizer 76 is stopped in step (d), but it is not necessary to stop the pressurizer 76 at this point. The pressurizer 76 may be operating before the first partition 70 is opened and may continue to operate while the first partition 70 is open.

[0054] The typical steps for carrying out cargo from inside the building 62 to the outside are as follows. The same applies when a person goes outside. (a) The third partition 74 is opened. (b) Move the cargo to the second space 80. (c) The third partition 74 is closed. (d) The pressurizer 76 is operated to create a positive pressure in the first space 78. (e) Open the first partition 70. (f) Open the second partition 72 and move the cargo outside the building 62. (g) The first partition 70 and the second partition 72 are closed and the pressurizer 76 is stopped.

[0055] The effects of this embodiment will be described below.

[0056] In this embodiment, the facility 60 includes a first partition 70 covering an entrance / exit 68 of a building 62, a second partition 72 forming a first space 78 between itself and the first partition 70, and a pressurizer 76 that puts the first space 78 under positive pressure relative to the outside. Since the first space 78 is under positive pressure, when the first partition 70 is opened, for example, to bring in cargo or the like, the air in the first space 78 flows outward. Even if there are insects near the first partition 70, the insects are prevented from entering the first space 78. This prevents insects from entering through the entrance / exit 68.

[0057] From the viewpoint of effectively preventing insects from entering by the air flow from the first space 78, the pressure in the first space 78 when the first partition 70 is opened is preferably 15 Pa or more. From the viewpoint of reducing the cost of making the first space 78 positively pressurized, the pressure in the first space 78 when the first partition 70 is opened is preferably 20 Pa or less.

[0058] In this embodiment, the facility 60 includes a third partition 74 that defines a second space 80 between the third partition 72 and the second partition 72. For example, when cargo or the like is brought in, the cargo is temporarily placed in the second space 80, the second partition 72 is closed, and then the third partition 74 is opened, thereby more effectively preventing insects from entering the building 62.

[0059] In this embodiment, the volume of the first space 78 is smaller than the volume of the second space 80. By reducing the volume of the first space 78, the first space 78 can be efficiently made to have a positive pressure with respect to the outside. This contributes to reducing the cost of making the first space 78 a positive pressure.

[0060] The pressurizer 76 is preferably an air jet. After the first partition 70 opens, the pressure in the first space 78 drops and approaches atmospheric pressure. Even in this case, by using an air jet for the pressurizer 76, an air "curtain" can be formed in the first space 78. This makes it possible to effectively prevent insects from passing through the second partition 72 into the second space 80 even after the first partition 70 and the second partition 72 are opened.

[0061] It is preferable that the first partition 70 has light-blocking properties. Many insects have the tendency to gather around light. By making the first partition 70 light-blocking, light inside the building 62 is prevented from leaking out through the first partition 70. This prevents insects from gathering around the first partition 70.

[0062] Although not shown, the facility 60 does not necessarily have to have the third partition 74. The inside of the second partition 72 may be the interior of the facility 60.

[0063] Although not shown, in a facility according to yet another embodiment, the first partition is provided with an ultraviolet absorbing material, and the facility further includes an ultraviolet generator outside the building. This facility is the same as the facility 60 in FIG. 6 except for the first partition and the ultraviolet generator. The ultraviolet generator irradiates ultraviolet light toward the first partition from a position away from the building. In this embodiment, the ultraviolet generator irradiates the entire first partition. The ultraviolet generator may also irradiate a portion of the first partition.

[0064] In this embodiment, the first partition is provided with an ultraviolet ray absorber, and the ultraviolet ray generator irradiates the ultraviolet ray absorber with ultraviolet ray. The ultraviolet ray is attractive to insects. Because the ultraviolet ray absorber absorbs the ultraviolet ray, reflection of the ultraviolet ray at the first partition is suppressed. Because reflected light from the first partition is suppressed, insects approaching the entrance / exit are not attracted toward the entrance / exit. Insects approaching the entrance / exit are attracted toward the ultraviolet ray generator. This prevents insects from entering through the entrance / exit.

[0065] As described above, in this embodiment, insects are prevented from entering the building. From this, the superiority of this embodiment is clear.
