Definitions
- microorganisms such as viruses, bacteria, fungi, various allergens (especially pathogenic microorganisms) floating in the air or adhering to walls or the like in human living rooms, working spaces or livestock raising rooms are positive ions and
- the present invention relates to an indoor cleaning method for removing pathogenic effects by using negative ions.
- Patent Document 1 a technique for purifying air in a living room by releasing positive ions and negative ions into the living room is actively used (see Patent Document 1).
- an ion generator that generates positive ions and negative ions is arranged in the middle of an air passage that discharges air current in a space to be cleaned, and the positive ions and negative ions are arranged. Ions are discharged to the outside space.
- the function of purifying the space with positive ions and negative ions is to remove dust and odors in the room with a filter and to adjust the temperature and humidity in the room appropriately. It is only an additional function that accompanies the original functions of the air conditioner and the air conditioner. In other words, the product was not developed with an emphasis on the function of positive ions and negative ions.
- the average ion concentration in the air in the room is 2,000 ions / cm 3 to 3
- the air cleaner or air conditioner uses the same room space before removing the malignant virus. There is a risk of infecting the human body.
- the volume of air that a person inhales with a single breath is about 500 cm 3 , which is a very small amount of air based on the space volume in the living room. From this, it is expected that it will take at least a few minutes for another person in the room to inhale and infect the virus that the person coughs and sneezes in the room and scatters around. . Therefore, it can be said that inactivating 99% or more of the virus in about 10 minutes after the virus scatters is a practical level for preventing the virus infection.
- norovirus is said to be infected by inoculation of about 100 viruses, so if there are 10,000 viruses in the room, it will remain 100 even if 99% is removed. Although the possibility is still undeniable, if 99.9% can be removed in a short time, there are only 10 remaining viruses, so the probability of infection can be reduced considerably. That is, in the virus world, it is understood that there is a difference in the probability of infection between the removal rate of 99% and the removal rate of 99.9%, although the difference is only 0.9%.
- microorganisms include viruses, bacteria, molds, and allergens that cause an allergic reaction in the human body. And when this microorganism causes an inconvenient action such as a disease for the human body, it is called a pathogenic microorganism. In addition, an adverse effect caused by the microorganisms on the human body is called a pathogenic effect, and elimination of the pathogenic effect is called removal. Therefore, inactivating viruses, killing bacteria and fungi, decontaminating allergens to eliminate their action, and the like correspond to removing the pathogenic action of microorganisms.

- the present invention is characterized in that the concentration of the positive ions and negative ions in the indoor air is 30,000 / cm 3 or more. According to this, it becomes possible to suppress the growth of the attached mold.
- the present invention is characterized in that the concentration of the positive ions and the negative ions in the indoor air is set to 50,000 / cm 3 or more. According to this, it is possible to remove 99.9% or more of the pathogenic action of the suspended virus in a short time and 99% or more of the pathogenic action of the attached bacteria.

Formed apart. Therefore, ion loss due to cancellation of positive ions and negative ions is prevented, and a large amount of positive ions and negative ions can be diffused in the room.
- the present invention is characterized in that in the above-described indoor cleaning method, a partition part is provided that partitions the positive ion generation part and the negative ion generation part along an air flow.
- the amount of positive ions generated from the positive ion generator and negative ions generated from the negative ion generator may be 50 cm away from the generator. It is characterized by being 1.5 million pieces / cm 3 or more.
- the present invention is characterized in that, in the above-described indoor cleaning method, an air flow is sent out from the air outlet in a substantially horizontal direction, and an upper air blowing speed is made higher than a lower air blowing speed.
- the high-velocity air stream blown out from the upper part of the outlet becomes an air curtain, and ions contained in the lower-speed air stream are supplied to the lower part of the living room. Accordingly, diffusion of ions upward is suppressed by the air curtain, and the above-mentioned 10,000 ions / cm 3 are placed in a space below a certain floor height (for example, the height of a person's height) in the living room. It can be widely distributed with the above ion concentration.

(1)細胞を用いた浮遊ウイルスの感染能力評価その1
プラスイオン及びマイナスイオンの存在する環境で浮遊インフルエンザウイルスの感染能力低減効果を検証することを目的として、細胞を用いた検証試験を実施した。図28に示すように、容積1m3チャンバー内に実施形態で説明したイオン発生器とチャンバー内空気の空気撹拌用のファンを設置した。次いで、イオン発生器から発生したプラスイオン及びマイナスイオンをファンで撹拌し、空間中のプラスイオン及びマイナスイオンの濃度が50,000個/cm3の均一な濃度となるように維持した。そして、H5N1型トリインフルエンザウイルスをチャンバー内に噴霧し、噴霧終了直後から10分間及び噴霧終了後5分後から10分間、それぞれチャンバー内の浮遊ウイルスを吸引回収し、その感染力価をウイルス研究分野で一般に用いられるTCID50法(段階的に希釈したウイルス液を細胞へ接種し感染力を調べる方法、図29参照)で調べた。ここで、感染力価とは、ウイルスの細胞への感染能力を表す指標である。その結果、ウイルスの感染力価(感染能力)は、約10分という短時間で約99.9%減少することが確かめられた。なお、イオン濃度7,000個/cm3で同様の実験での10分での除去率は99.0%であった。また、H1N1型ヒトインフルエンザウイルスの場合は同様の実験で25分での除去率はイオン濃度7,000個/cm3で99.7%、イオン濃度50,000個/cm3で約99.97%であった。このように、イオン濃度7,000個/cm3以上で浮遊ウイルスの有意な除去効果が見られ、イオン濃度を増すほどその効果が高まるという結果が得られた。
図28に示すように、容積1m3チャンバー内に本実施形態で説明したイオン発生器とチャンバー内空気の空気撹拌用のファンを設置した。次いで、イオン発生器から発生したプラスイオン及びマイナスイオンをファンで撹拌し、空間中のプラスイオン及びマイナスイオンの濃度が50,000個/cm3の均一な濃度となるように維持した。そして、H5N1型トリインフルエンザウイルスをチャンバー内に噴霧し、噴霧終了後5分後から10分間チャンバー内の浮遊ウイルスを吸引回収し、細胞に接種し3日間の細胞の変化を調べた。その結果、プラスイオン及びマイナスイオンを作用させていないウイルスを接種した細胞は、接種3日後で変形し破壊されているのに対し、プラスイオン及びマイナスイオンを作用させたウイルスを接種した細胞では、ほとんど変化が見られず正常な形状を保っていた。このことから、プラスイオン及びマイナスイオンの作用によりウイルスの細胞感染力を抑制することが確認された。
プラスイオン及びマイナスイオンの存在する環境で浮遊インフルエンザウイルスの感染能力低減効果を検証することを目的として、小動物(ヒヨコ)を用いた検証試験を実施した。図30に示すように、イオン発生器と空気撹拌用のファンを設置した容積1m3のチャンバー(イオンとウイルスの接触を行なう室)及び容積270Lのヒヨコの飼育室を2本のチューブで接続し、チャンバーとヒヨコ飼育室を空気が循環できるようにする。次いで、チャンバーとヒヨコ飼育室との間の通気を遮断し、プラスイオン及びマイナスイオンの濃度が3,000、7,000、25,000又は50,000個/cm3の均一な濃度となるように設定したチャンバー(それぞれ、試験区1、2、3又は4とする)内にウイルス濃度105TCID50/1mLのH3N2型トリインフルエンザウイルス液をネブライザーにより25分間かけ全量噴霧を行なう。そして噴霧後1時間、チャンバー内でイオン発生器から前記濃度を維持するようにプラスイオン及びマイナスイオンを発生させ、ファンにてイオンとウイルスの攪拌を行なう。比較のため、イオン発生器を動作させないでイオン濃度を0に設定したチャンバー(対照区とする)内でウイルス液を噴霧、撹拌を行った。
