Description

[Technical field]

[0001] The present invention relates to an antibacterial passageway which has antibacterial and antiviral properties. [Background technology]

[0002] It has been known for some time that a sterilizing space can be formed in a passageway connecting an isolation ward and a general ward to reduce the activity of bacteria and viruses attached to people and objects passing through. Patent Document 1 discloses a sterilization system unit for hospitals that sprays a sterilizing agent into the passageway space to sterilize it.

[0003] In addition, at the entrance to clean rooms where electronic parts, food, etc. are manufactured, air shower rooms are provided in which a current of air is blown toward people entering and leaving to prevent the bringing in of dust adhering to the human body or clothing.

[0004] With the recent increase in the number of people infected with the new coronavirus, households may take measures such as brushing off dust from clothes at the entrance to prevent the virus from being brought into the home from outside. However, the virus attached to the brushed off dust is dispersed into the air, and even if it adheres to a wall or floor, it is not killed, so the actual effectiveness of such measures is questionable. In addition, it is difficult to install large-scale equipment such as a hospital sterilization room in a residence, and there are health concerns about spraying a disinfectant liquid toward people.

[0005] [Patent Document 1] JP 2009-261596 A Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, an object of the present invention is to provide an antibacterial passageway that can be easily installed at the entrances of homes, facilities, etc. and that is expected to have not only antibacterial but also antiviral effects. [Means for solving the problem]

[0007] The antibacterial passage of the present invention, which has been made to solve the above problems, has an inner surface of a tunnel-shaped passage made of a copper plate made of pure copper or a copper alloy. An antibacterial passage, in which a compression-molded plate made of copper material shavings is laid on the floor of the tunnel-shaped passage. The copper alloy may be any one of beryllium copper, phosphor bronze, and zirconium copper.

[0008] In addition, the tunnel-like passage is installed at the entrance or exit of the building or room. preferable. Effect of the Invention

[0009] The antibacterial passage of the present invention is a tunnel-shaped passage whose inner surface is made of copper plates made of pure copper or copper alloy, so that the antibacterial and antiviral effects of copper can reduce the activity of bacteria and viruses attached to the inner surface of the passage. Therefore, if dust attached to clothes is brushed off when passing through the antibacterial passage, the scattered bacteria and viruses will lose their activity when they come into contact with the copper plates, and it is possible to prevent them from being brought into the room. In addition, the antibacterial passage of the present invention has a simple structure and can be manufactured at low cost, and does not require consumables such as disinfectant liquid, so there is an advantage that there is no running cost.

[0010] In addition, the floor of the passageway is also covered with compressed copper shavings. So, It is possible to capture bacteria and viruses that have fallen downward and reduce their activity, and also to provide an anti-slip effect. [Brief description of the drawings]

[0011] [Figure 1] FIG. 1 is a perspective view showing a first embodiment of the present invention. [Diagram 2] FIG. 11 is a perspective view showing a second embodiment of the present invention. [Diagram 3] FIG. 1 is a perspective view showing an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An embodiment of the present invention will be described below. FIG. 1 shows the first embodiment of the present invention. Reference form The side walls and ceiling of the tunnel-shaped passage 10 are made of copper plates 11.

[0013] The copper plate 11 is a plate made of pure copper or a copper alloy. As has been known for some time, copper is a metal with antibacterial and antiviral properties. The mechanism is thought to be that copper ions make holes in the envelope membrane of the virus, and free radicals generated by the copper ions decompose the genetic material of bacteria and viruses. According to a research team at the National Institutes of Health (NHI) in the United States, the survival time of the new coronavirus is 72 hours on the surface of plastic or stainless steel, 24 hours on the surface of cardboard, and 4 hours on the surface of copper, confirming that copper also has an antiviral effect against the new coronavirus.

[0014] Since copper ions thus exert antibacterial and antiviral effects, it is not necessary to use pure copper, and copper alloys such as beryllium copper, phosphor bronze, and zirconium copper may also be used. Beryllium copper and phosphor bronze are widely used as conductive spring materials, and zirconium copper is an industrial material that is widely used as a material for welding contact tips, so it has the advantage of being easily available.

[0015] Conventionally, copper powder and copper fiber have been used as antibacterial materials that utilize the antibacterial and antiviral effects of copper, but these require a lot of processing costs to be made into fine powder or fine fibers. In comparison, the copper plate 10 used in the present invention has the advantage that the processing costs are low and the material costs can be kept low by making the plate thinner.

[0016] The first one shown in FIG. Reference form In this example, the entire passage 10 is made of copper plate 11. However, Fig. 2 Shown in Second Reference As shown in the embodiment, the side walls and ceiling of the passage 10 may be made of a base material 12 made of wood or resin, and a copper plate 11 may be attached to the inner surface of the base material 12. In order to obtain the antibacterial and antiviral effects of copper, it is not necessary to make the plate thick. Reference form In the second case, a copper plate 11 of a certain thickness is required to ensure the strength of the passage 10. Reference form In this case, a thin copper plate 11 can be used, and the manufacturing cost can be reduced.

[0017] From the viewpoint of antibacterial and antiviral effects, the longer the length of the passage 10, the better, but if it is too long, a large installation space is required, which may be a hindrance when installing indoors, so a length of about 0.5 to 2 m is practical. If the length of the passage 10 is too short, the surface area of ​​the copper plate 11 that comes into contact with airborne bacteria and viruses is reduced, which is undesirable.

[0018] If an antibacterial passage constructed in this way is installed at the entrance of a building or room, and dust adhering to clothes is brushed off inside the passage 10 when passing through the entrance, the scattered bacteria and viruses will be inactivated by contact with the copper plate 11, and it is possible to prevent them from being brought into the room. Furthermore, since copper is a metal that is safe for the human body and is used in dishes, pots, etc., there are no health concerns as with spraying a germicidal liquid. Moreover, the copper plate 11 maintains its copper luster for a long period in the air, so the aesthetic appearance is not diminished.

[0019] Since the larger the surface area, the greater the antibacterial and antiviral effects, it is possible to make the surface of the copper plate 11 uneven or to form grooves. Furthermore, in order to more actively remove dust adhering to the surface of the human body or clothing, it is also possible to provide a blowing means such as a fan to blow air.

[0020] The first one mentioned above Reference form and the second Reference formIn the example, the side walls and the inner surface of the ceiling of the passageway 10 are made of copper plates 11, but it is highly likely that the dust dispersed in the air will eventually fall onto the floor together with the adhering bacteria and viruses. Embodiment In this example, a compression molded plate 13 made of copper shavings was laid on the floor of a tunnel-like passage 10.

[0021] When cutting copper materials with a lathe or milling machine, a large amount of shavings is generated. As shown in the enlarged view in Figure 3, these shavings are fine spirals, and although they vary depending on the cutting conditions, their width is about 1 to 10 mm, the spiral diameter is about 1 to 10 mm, and their thickness is about several μm to several tens of μm. Therefore, their surface area becomes very large. If these shavings are pressed and compressed, they become entangled with each other, and falling dust and bacteria and viruses adhering to the surface can be captured and sterilized within the internal space.

[0022] In addition, because the compression-molded plate 13 made from shavings has fine irregularities, it has a larger coefficient of friction than the copper plate 11, and exhibits an anti-slip effect. Moreover, since the shavings were previously disposed of as waste, they can be obtained at low cost. It is not necessary for the entire floor surface to be made of compression-molded plates 13, and they can be placed at appropriate intervals.

[0023] As explained above, the antibacterial passage of the present invention can be easily installed at the entrances of residences, facilities, etc., and has the advantage of being able to exert not only antibacterial but also antiviral effects. The installation location may be outdoors or indoors, and it can be installed at the entrances of general homes and apartment buildings, as well as hospitals and facilities. [Explanation of symbols]
