Description
本考案は、ウィルス・細菌、ホコリ等の拡散や、それによる汚染・感染の拡大を抑えることのできる空調設備を設けた教室、ブース、病室等の部屋に関する。 The present invention relates to a room such as a classroom, a booth, a sickroom, etc., which is provided with an air-conditioning system capable of suppressing the spread of viruses, bacteria, dust, etc., and the spread of contamination and infection caused thereby.
新型コロナウィルス（ＣＯＶＩＤ−１９）、ＳＡＲＳ（重症急性呼吸器症候群）、新型インフルエンザ等の大流行によって、ウィルスの拡散、感染の拡大を如何にして防ぐかが、喫緊の課題となっている。
特に職場や学校、病院、公共機関、店舗等の不特定多数の人が集合する屋内におけるウィルスの拡大や感染を防止することが重要である。
また飲食品を扱う店舗、工場等の衛生管理を必須とする室内において、人や物品に付着して、ウィルスや細菌、ホコリ等が仮に侵入しても、その影響を最小限に留めることも重要である。
ここで、研究機関や学校での実験の際に、意図せぬ塵芥や細菌・ウィルス等の混入を防ぐための、いわゆるクリーンベンチは公知である（例えば特許文献１等参照）。
また特許文献２には、医療の分野で求められる細菌・ウィルス等が除去された清浄空間を提供する空間清浄度保持装置が記載されている。
しかしこれらの装置等は比較的狭い空間を清浄にすることを目的としたものであり、職場や学校等の広い空間を清浄にすることは難しい。
特許文献３には、新型インフルエンザ等のパンデミックが発生した場合に、管理対象区画における感染症による汚染を防止し、該区画の保全を行うための管理対象区画保全方法が記載されており、パーソナル執務スペースで用いる空気清浄装置が開示されている。
しかしながら、これら設備では、様々な機構を必要とし、また各区画で気圧を変えるなど、設置にかなりの費用が掛かると思われる。またクリーンベンチは実験用に手元を隔離するに留まる。
またいずれの先行技術においても、給気口と吸気口の位置が完全には対応していないため、空気の流れが一方向とはならず、乱流等により細菌・ウィルス等の一部が拡散してしまう恐れがあった。
It is an urgent issue how to prevent the spread of virus and the spread of infection due to the pandemic of new coronavirus (COVID-19), SARS (Severe Acute Respiratory Syndrome), and new influenza.
In particular, it is important to prevent the spread and infection of viruses inside the workplace, school, hospitals, public institutions, stores, etc. where many unspecified people gather.
In addition, it is important to minimize the effect of viruses, bacteria, dust, etc., even if they adhere to people or goods in a room where hygiene management is essential in stores handling food and drinks, factories, etc. Is.
Here, a so-called clean bench is known to prevent unintended contamination of dust, bacteria, viruses, etc. during experiments at research institutions and schools (see, for example, Patent Document 1).
Patent Document 2 describes a space cleanliness retention device that provides a clean space free of bacteria, viruses, etc., which is required in the medical field.
However, these devices are intended to clean a relatively narrow space, and it is difficult to clean a large space such as a workplace or school.
Patent Document 3 describes a managed area conservation method for preventing contamination by infectious diseases in a managed area and performing conservation of the area when a pandemic such as a new strain of influenza has occurred. An air purifier for use in a space is disclosed.
However, in these facilities, various mechanisms are required, and it is considered that the installation costs a lot because of changing the atmospheric pressure in each section. Also, the clean bench keeps hands isolated for testing.
In addition, in any of the prior arts, the position of the air supply port and the position of the air intake port do not correspond completely, so the air flow is not in one direction, and some bacteria, viruses, etc. diffuse due to turbulence etc. I was afraid to do it.
ウィルスが空気感染・プラズマ感染・マイクロ飛沫感染する場合には、特に、室内や一部ブースを十分に換気したとしても、雰囲気中で乱流が生じたり、空気が水平方向に流れることにより、周囲の人や風下にいる人への感染リスクが大きくなる可能性がある。本考案は、この可能性を無くすために、より広い空間での下向きの空気流を可能な限り維持するものである。
そして、学校や職場、病院、公共機関、店舗等の不特定多数の人が集まる、屋内の比較的広い空間、例えば部屋全体、又は室内の特に限定されたブースにおけるウィルスや細菌の拡散、感染の拡大を防止することを課題とする。
When a virus infects air, plasma, or micro droplets, turbulence may occur in the atmosphere or air may flow horizontally even if the room or some booths are well ventilated. Can increase the risk of transmission to people in and downwind. The present invention attempts to eliminate this possibility by maintaining downward airflow in a larger space as much as possible.
In addition, a relatively large indoor space where a large number of unspecified people such as schools, workplaces, hospitals, public institutions, and shops gather, for example, the entire room, or the spread of viruses and bacteria in a particularly limited booth inside the room, The challenge is to prevent expansion.
