Abstract
Description
この発明は大小、屋内空気中の細菌及びウイルスを減菌、滅菌させることを目的とした空調機器の仕組みに関する。The present invention relates to a mechanism of an air conditioner for the purpose of sterilizing and sterilizing bacteria and viruses in large and small indoor air.
波長260nm付近の7.5J/m2以上の紫外線照射による直接的な空気中の細菌及びウイルスの減菌、滅菌及び二酸化チタン光触媒反応による細菌、ウイルスの不活性化Direct sterilization of bacteria and viruses in the air by irradiation with ultraviolet rays of 7.5 J / m 2 or more near the wavelength of 260 nm, sterilization and inactivation of bacteria and viruses by titanium dioxide photocatalytic reaction.
紫外線による細菌、ウイルスへの殺菌を空気清浄の副次的な目的とした機器は従来から存在する。しかし、それらは小規模な室内用に限られ、また、空気中での効果的な紫外線照射には限界があった。特に人体への悪影響を避ける為、外部暴露が極力少ない機械内部での紫外線照射に限られることになり、その場合に十分な効果を生む照射時間が得られないことが大きな課題である。There have been devices for the secondary purpose of air purification to sterilize bacteria and viruses with ultraviolet rays. However, they were limited to small indoor use, and effective UV irradiation in the air was limited. In particular, in order to avoid adverse effects on the human body, the irradiation is limited to ultraviolet rays inside the machine where the external exposure is as small as possible, and in that case, it is a big problem that the irradiation time that produces a sufficient effect cannot be obtained.
この課題を解決するために、第一の発明は特殊な除菌ユニットを発明した。これをラビリンスチャネルと称する。また、第二の発明はこの除菌ユニットを用いて商用ホール規模の空気中の細菌、ウイルスを減菌、滅菌することを主目的とした機器である。これを空間除菌機と称する。In order to solve this problem, the first invention invented a special sterilization unit. This is called a labyrinth channel. The second invention is a device whose main purpose is to sterilize and sterilize bacteria and viruses in the air on a commercial hall scale using this sterilization unit. This is called a space sterilizer.
除菌ユニット(ラビリンスチャネル)
この課題を解決するために導入した空気を折り畳むような形状の空気路を通すことで*照射時間を確保することが出来る。これにより、その間に複数の265nm紫外線LEDを設置した仕切りパネル内を通過する際に十分な長さの*照射時間を与えることが出来る共に、照射距離を近くすることで効果的な殺菌効果を得られる。また、設備をコンパクトにまとめることが可能となる。 さらに、通路内面に二酸化チタンをコーティングし、紫外線による直接の殺菌効果と光触媒反応によって発生するOHラジカルの強い酸化反応で細菌、ウイルスの無害化に強く作用することが出来るもの。ここでは高速で通過する通路内のパネルが振動することによって騒音を発生させない為に、仕切り内部に樹脂材料をクッション材として使用する、もしくは仕切りパネル素材を耐振動性のあるチタン、及びチタン合金材等の使用するもの。図2、図3、図4、及び図5
*照射時間
空気中ウイルスの90%殺菌率 D値=7.5J/m2
殺菌線照度E(W/m2)と照射時間t(秒)の積[殺菌線量(J/m2)]
照度E=光出力(W)/距離d(m)2
265nm UV LED光出力 50mW
ラビリンスチャネル内壁面間隔<0.1m (高さ1.5m、幅1.2m、奥行0.9mの場合)
以上からD値7.5を満たす照射時間(t)の必要値を1.5秒と計算される。
(実際には複数の光源からの照射があり、且つ、距離を最大値で設定している為、十分 以上の効果を見込むことが出来る)Sterilization unit (labyrinth channel)
* Irradiation time can be secured by passing through an air passage that is shaped to fold the air introduced to solve this problem. As a result, a sufficient length of * irradiation time can be given when passing through the partition panel in which a plurality of 265 nm ultraviolet LEDs are installed, and an effective bactericidal effect can be obtained by shortening the irradiation distance. Be done. In addition, the equipment can be compactly integrated. Furthermore, titanium dioxide is coated on the inner surface of the passage, and it can strongly act to detoxify bacteria and viruses by the direct bactericidal effect by ultraviolet rays and the strong oxidation reaction of OH radicals generated by the photocatalytic reaction. Here, in order not to generate noise due to vibration of the panel in the passage passing at high speed, a resin material is used as a cushion material inside the partition, or the partition panel material is made of vibration-resistant titanium and titanium alloy material. Etc. used. 2, FIG. 3, FIG. 4, and FIG.
* Irradiation time 90% sterilization rate of virus in air D value = 7.5J / m 2
Sterilization line Illuminance E (W / m 2 ) and irradiation time t (seconds) product [sterilization dose (J / m 2 )]
Illuminance E = light output (W) / distance d (m) 2
265nm UV LED light output 50mW
Labyrinth channel inner wall surface spacing <0.1m (height 1.5m, width 1.2m, depth 0.9m)
From the above, the required value of the irradiation time (t) satisfying the D value 7.5 is calculated to be 1.5 seconds.
(Actually, there are irradiations from multiple light sources, and the distance is set to the maximum value, so more than sufficient effects can be expected.)
空間除菌機
ラビリンスチャネルの効果により効率的に、また、大容量が可能になり、大きなホール規模の空気中の細菌及びウイルスを減菌、滅菌させることが出来る。構造は正面部から空気を取り込み、フィルターで濾過後にラビリンスチャネルに導入される。中では効果を得られる風速を維持するためにインバーターで制御されたモーターによりファンが回転し、上部から処理された空気を排出する。図1The effect of the space sterilizer labyrinth channel enables efficient and large capacity, and can sterilize and sterilize bacteria and viruses in the air on a large hall scale. The structure takes in air from the front, filters it and then introduces it into the labyrinth channel. Inside, a fan is rotated by a motor controlled by an inverter to maintain a wind speed that is effective, and the processed air is discharged from the top. Figure 1
第一発明を組込んだ第二発明である空間除菌機は十分な紫外線照射効果と光触媒効果により導入空気の90%以上のウイルスを死滅若しくは不活性化させることが出来る。これを連続的に使用することでホール内の空気を安全なものへ変化させることが出来る。The space sterilizer, which is the second invention incorporating the first invention, can kill or inactivate 90% or more of the viruses in the introduced air by a sufficient ultraviolet irradiation effect and photocatalytic effect. By using this continuously, the air in the hall can be changed to a safe one.
この発明の空間除菌機の一実施形態を図1に示す。
本体前面部から取り入れられた空気はフィルターを通過後に除菌ユニット(ラビリンスチャネル)に導入され細菌やウイルスを減菌、除菌した上で上部吹き出し口から排出される。
また、除菌ユニット(ラビリンスチャネル)の一実施形態を図2に示す。
除菌ユニット内部には265nm UV LEDモジュールが多数配置され、さらに内部は二酸化チタンがコーティングされている。この一実施形態を図3、図4、及び図5 で示す。An embodiment of the space sterilizer of the present invention is shown in FIG.
The air taken in from the front part of the main body is introduced into the sterilization unit (labyrinth channel) after passing through the filter, and after sterilizing and sterilizing bacteria and viruses, it is discharged from the upper outlet.
Moreover, one embodiment of the sterilization unit (labyrinth channel) is shown in FIG.
A large number of 265 nm UV LED modules are arranged inside the sterilization unit, and the inside is coated with titanium dioxide. This embodiment is shown in FIGS. 3, 4, and 5.
