Description

Sterilization Illuminator with Fan {STERILIZATION ILLUMINATION APPARATUS PROVIDED WITH FAN}

The present invention relates to a fan-equipped antibacterial lighting device capable of efficiently removing contaminants suspended in air at the same time as illumination.

Conventionally, indoor air contains various biological contaminants (e.g., influenza virus, corona virus, MRSA (methicillin resistant Staphylococcus aureus), mold, allergens (mite carcasses, allergens from pets, etc.)) However, air pollutants such as active oxygen are suspended and are harmful to the human body.

In addition, various methods have been developed to remove the harmful air pollutants from the air, and one of the effective apparatuses is a sterilization apparatus including a cation generator and an anion generator (for example, Japanese Patent Laid-Open No. 2006-34957). Is proposed.

This sterilizer flows air from the cation generator to the anion generator, and firstly, a positive voltage is applied to the air from the cation generator to decompose water molecules in the air to generate hydrogen ions (H ⁺ ).

4H ₂ O → 2H ₂ O + O ₂ + 4H ⁺

On the other hand, the negative ion generating unit applies a high voltage of a negative component to the air to generate electrons (e ⁻ ) and oxygen ions (O ₂ ⁻ ).

^{_{O 2 + e - → O 2}} -

When the hydrogen ions generated in the cation generator are close to the anion generator, the hydrogen ions combine with the electrons generated in the anion generator to form a hydrogen atom (H).

H ^{+ +} e ^- → H

Hydroperoxy radical (HOO ⁻ ) is generated by the combination of hydrogen atom (H) and oxygen ion (O ₂ ⁻ ). The hydroperoxy radical (HOO ⁻ ) surrounds and attaches a positively charged biological contaminant, destroying the hydrogen bonds of the protein structure on the surface of the biological contaminant, thereby destroying the biological contaminant. At the same time, the reacted HOO-radical returns to water (H ₂ O) and back to the air.

On the other hand, part of the hydrogen atom (H) is combined with the active oxygen (OH-radical) suspended in the air, becomes a water molecule to neutralize the active oxygen (OH-radical).

In addition, this active oxygen (OH-radical) is the most toxic (oxidative power) of the active oxygen species, known as the causative agent of skin aging and skin diseases.

In this manner, the sterilizing apparatus can effectively remove harmful air pollutants from the air, and thus is effective for cleaning indoor air. And it is conceivable to use a blowing fan as a means for supplying air to the sterilizer. That is, if a fan-mounted sterilizer is constructed by installing a fan in the vicinity of the sterilizer, air is blown out by the fan to drive the sterilizer, and air flows from the cation generator to the anion generator of the sterilizer, and the fan is cleaned while the air is cleaned. It is discharged from the mounting sterilizer to the outside. The discharged air is cleaned, for example, by circulating the room.

However, in the case of installing the fan-mounted sterilizer in the ceiling of a building, for example, the installation place is limited because the installation must be avoided by a lighting device or other various devices installed on the ceiling, and the number of installation is limited, There is a possibility that the installation place may not be uniform. If the number of installations is limited, sufficient sterilization of indoor air will not be performed. In addition, when the installation place is not uniform, uniform sterilization of the entire indoor air is not performed.

On the other hand, there is a conventional lighting device using a fluorescent lamp for illuminating an indoor light. However, in recent years, as a lighting apparatus of this kind, it has been performed to use a light emitting diode instead of an incandescent lamp or a fluorescent lamp. Since light emitting diodes consume less power and have a longer lifespan than incandescent lamps, fluorescent lamps, and the like, energy saving can be achieved, which is promising as a lighting device in the future. However, since the light emitting diode is weak in heat, when it is used in a lighting apparatus, there is a possibility that the life may be shortened by its heat generation, and a cooling means for preventing this is required separately.

Since the outer periphery of the reflecting plate 60 is located at almost the same height on all four sides, the inner periphery formed between the apparatus main body 30 (or the wall surface 110) and the reflecting plate 60 by mounting the outer periphery on the wall surface. The space 70 becomes an almost closed space.

5 is a perspective view of the air sterilization unit 80 viewed from the lower side, and FIG. 6 is a perspective view of the air sterilization unit 80 viewed from the upper side. As shown in both figures, the air sterilization unit 80 flows air from the suction port 83 toward the discharge port 85 to the case 81 having the suction port 83 and the discharge port 85. And a sterilization apparatus 100 for supplying active oxygen and oxygen ions to the air flowing in the case 81.

The case 81 is a molded article made of synthetic resin, which has a substantially rectangular elongated box shape, and an inlet port 83 is formed on the lower surface of one end, and a discharge port 85 is formed on the lower surface of the other end. Between the suction port 83 and the discharge port 85, the duct part 87 which connects both is formed, and the opening 89 is formed in the upper surface of the duct part 87. As shown in FIG.

The sterilizing apparatus 100 is housed in the recessed part formed in the bottom face of the duct part 87 so that the upper surface of the sterilizing apparatus 100 and the bottom surface in the duct part 87 may become substantially the same surface. 7 is a perspective view of the sterilization apparatus 100. As shown in FIG. 7, the sterilizing apparatus 100 has a substantially rectangular shape and is provided with a cation generating unit 130 near one end of the upper surface of the base 110 covered by the resin case, and the base 110. The negative ion generating part 150 is provided in the vicinity of the other end part of an upper surface, and is comprised.

The cation generating unit 130 is configured to house the flat ceramic plate 131 in the concave portion formed on the upper surface of the base 110 so that the upper surface thereof is exposed. Discharge electrodes are provided on the upper side of the ceramic plate 131 and induction electrodes are disposed on the lower side of the ceramic plate 131. Plasma discharge is generated by applying a high voltage of positive component (for example, about 3 kV) between both electrodes, thereby generating moisture in the surrounding air. (H ₂ O) is ionized to generate hydrogen ions (H ⁺ ).

4H ₂ O → 2H ₂ O + O ₂ + 4H ⁺

The negative ion generating unit 150 is configured by providing a protecting unit 153 so as to surround the needle-shaped electrode 151 in a U-shape. By applying a high voltage of a negative component (for example, about -4 kV) to the needle-shaped electrode 151, positive ions gather around the needle-shaped electrode 151 by plasma discharge, and a large amount of electrons are generated from the needle-shaped electrode 151. (e ^-) are emitted in the air. Because the large amount of electrons released into the air is so unstable, it is trapped in oxygen molecules (O ₂ ) to form superoxide anions (O ₂ ⁻ ). That is, a high voltage of a negative component is applied to the needle-shaped electrode 151 to generate electrons and superoxide anions. At the same time, when electrons are emitted from the needle-shaped electrode 151, electrons are generated from the ceramic plate 131 and are combined with hydrogen ions passing around the needle-shaped electrode 151 to become active hydrogen (hydrogen atom; H).

H ^{+ +} e ^- → H

^{_{O 2 + e - → O 2}} -

Hydroperoxy radicals (HOO ⁻ ) are produced by the combination of these active hydrogens (H) and oxygen ions (O ₂ ⁻ ). The hydroperoxy radical (HOO ⁻ ) surrounds and attaches a positively charged biological contaminant to generate HOO-radical on the surface of the biological contaminant, destroying the hydrogen bonds in the protein structure on the biological contaminant surface, thereby destroying the biological contaminant. . At the same time, the reacted HOO-radical returns to water (H ₂ O) and back to the air.

On the other hand, a part of the active hydrogen (H) is combined with the active oxygen (OH-radical) suspended in the air, neutralizing the active oxygen (OH-radical) in the form of water molecules.

H + OH → H ₂ O

In order to effectively produce the above effect, air around the sterilization apparatus 100 flows as linearly as possible from the cation generator 130 side toward the anion generator 150 side and is generated in the cation generator 130. It is necessary to reliably supply the hydrogen ions (H ⁺ ) to the surroundings of the negative ion generating unit 150. In this embodiment, the air flowing over the cation generating unit 130 in the case 81 is the negative ion generating unit 150 The cation generator 130 is disposed on the upstream side and the anion generator 150 on the downstream side so as to flow the phase.

As shown in FIG. 4, the air sterilization unit 80 fixes the upper surface of the air sterilization unit 80 to the mounting plate 31 of the apparatus main body 30 by the mounting unit 91, thereby fixing the opening 89 to the mounting plate 31. Is blocked).

As shown in FIG. 3, a reflecting plate 60 is provided below the apparatus body 30 mounted on the ceiling so as to cover the apparatus body 30, which is also mounted on the ceiling. The discharge port 85 of the case 81 of the air sterilization unit 80 is exposed to the air discharge port 69. At this time, each lamp socket 33 protrudes toward the lower surface side of the reflecting plate 60. And as shown in FIG. 2, when the terminal connection part 13 of the both ends of LED tube light 10 is couple | bonded with each lamp socket 33, assembly of the fan-mounted germicidal lighting apparatus 1-1 is completed. In addition, the cooking order is one example, it goes without saying that it may be assembled using a variety of other assembling order.

In the fan-mounted bactericidal lighting device 1-1 configured as described above, for example, when the on / off switch installed indoors or outdoors is turned on, the power supply voltage is supplied to the LED tube light 10 through the power supply unit 35. The LED tube light 10 is illuminated brightly when applied. At the same time a power supply voltage is also applied to the air sterilization unit 80, the fan 90 is driven at the same time the sterilizer 100 is driven. When the fan 90 is driven, external air is sucked in from the inlet port 83, passes through the inside of the fan 90, and then passes through the duct part 87, so that the outside of the reflector plate 60 from the discharge port 85 ( On the lower side).

In addition, since the air sucked from the inlet port 83 is air in the inner space 70, and the air is discharged from the discharge port 85 to the outside of the inner space 70, the insufficient air in the inner space 70 is reflected by the reflector plate ( The external air is sucked in from the air intake port 67 provided on the curved surface 65 of 60 to be replenished. In the fan-mounted bactericidal lighting device 1-1, since the air suction port 67 is provided at a position facing the LED tube light 10 of the reflecting plate 60, the outside introduced into the interior space 70 is provided. Air passes before around the outer circumferential side of the LED tube light 10. As a result, heat of the LED tube light 10 generated by lighting is efficiently transmitted to the air, thereby cooling the LED tube light 10. As described above, since the LED tube light 10 is weak against heat, there is a risk that the lifespan of the built-in light emitting diode may be greatly shortened unless effective heat dissipation is performed. Effective cooling of the LED tube light 10 can be achieved without providing a special cooling means, and the life can be extended. In particular, in the case of the fan-mounted bactericidal lighting device 1-1, the surface facing the LED tube light 10 of the reflector 60 is formed in a yaw shape that accommodates a part of the outer circumference of the LED tube light 10. Since the air inlet 67 is provided in the curved surface 65, the outside air sucked in from the air inlet 67 reliably flows along the outer circumferential surface of the LED tube light 10, The LED tube light 10 can be cooled more effectively.

On the other hand, in the air sterilization unit 80, the hydrogen ions (H ⁺ ) generated by the plasma discharge of the cation generating unit 130 of the sterilization device 100 is carried by the air flow by the fan 90 anion generating unit ( 150) is carried nearby. Hydrogen ions (H ⁺ ) transported near the anion generator 150 are combined with electrons (e ⁻ ) generated by plasma discharge of the needle-shaped electrode 151 to become active hydrogen (H), and oxygen ions generated at the same time. Hydroperoxy radicals (HOO-) are produced by combining with (O ^{2 −} ). This hydroperoxy radical (HOO-) is blown downward from the discharge port 85 of the case 81 to the outside (lower surface side) of the reflecting plate 60 by air flow. Exhausted hydroperoxy radicals (HOO-), as described above, are biological contaminants in indoor air (e.g. influenza virus, corona virus, MRSA (methicillin resistant Staphylococcus aureus), mold, allergens (carcasses of mites) / Stools, allergens from pets, etc.) are effectively destroyed. At the same time, part of the active hydrogen (H) binds to and neutralizes the active oxygen suspended in the air. The discharged air purifies the entire room to effectively sterilize / clean the entire room. At the same time, the room temperature can be equalized by the air circulation.

The fan-equipped bactericidal lighting device 1-1 according to the present embodiment installs the air sterilization unit 80 (sterilization apparatus 100) on the lighting apparatus itself installed in the ceiling of a building, etc. ) Is not limited to the installation place or the number of installations, it is possible to easily install a sufficient number of air sterilization unit 80 uniformly, such as on the ceiling of the building, thereby enabling to perform a uniform and sufficient sterilization of the entire indoor air . In addition, since the air sterilization unit 80 is housed in the lighting fixture, it is also clean in appearance. In addition, in the case where the fan-mounted germicidal lighting apparatus 1-1 according to the present embodiment is installed in an existing building, an existing lighting apparatus (for example, a fluorescent lamp apparatus) is replaced with a fan-mounted germicidal lighting apparatus 1- according to the present invention. Since it is only necessary to replace it with 1), it is not necessary to provide an air sterilization unit 80 installation hole or the like separately on the ceiling, so that the installation can be facilitated.

At the same time, a voltage is applied to the fan 400 and the sterilizer 100 so that the fan 400 is driven and the sterilizer 100 is driven. When the fan 400 is driven, outside air is sucked from the air inlet 380, and after passing through the air passage 340, air is blown out from the air outlet 390 toward the outside (down) through the fan 400. Lose.

In the fan-mounted germicidal lighting apparatus 1-2, since the air flows through the air passage 340 facing the upper portion of the mounting plate 310 for heat dissipation, the heat of the light emitting plate 300 that generates heat by lighting. The heat conduction combined with the air through the mounting plate 310 can be efficiently cooled to the light emitting plate 300. As described above, the light emitting diode mounted on the light emitting plate 300 is weak in heat generation, and if its effective heat dissipation is not carried out, its life may be greatly shortened. Even without providing a cooling means, effective cooling can be achieved and the life of the light emitting diode can be extended.

On the other hand, from the sterilization apparatus 100, hydroperoxy radicals (HOO-) are generated in the same manner as in Example 1, and are discharged from the air discharge port 390 toward the outside (downward) in the air flow along with the active hydrogen (H). Hydroperoxy radicals (HOO-) effectively destroy biological pollutants in the indoor air, and at the same time, the active hydrogen (H) binds to and neutralizes the active oxygen suspended in the air. That is, the discharged air circulates through the entire room to effectively sterilize / clean the entire room. At the same time, the room temperature can be equalized by the air circulation.

Since the fan-mounted germicidal lighting device 1-2 according to the present embodiment can be installed as a lighting fixture installed in the ceiling of a building, etc., it can be easily and uniformly installed in a sufficient number of ceilings of a building. Uniform and sufficient sterilization of the whole can be performed. In addition, since the sterilizer 100 and the like are housed in the lighting fixture, they are also neat in appearance. In addition, in the case of installing the fan-mounted germicidal lighting apparatus 1-2 according to the present invention in an existing building, an existing lighting apparatus (for example, a fluorescent lamp apparatus) is replaced with the fan-mounted germicidal lighting apparatus 1-1 according to the present embodiment. It only needs to be replaced with 2), which facilitates the installation.

As mentioned above, although embodiment of this invention was described, this invention is not limited to the said Example, A various change is possible within the range of the technical idea described in the claim and specification and drawing. In addition, any shape, structure, or material that is not directly described in the specification and drawings are within the scope of the technical idea of the present invention as long as the action / effect of the present invention is exhibited.
