本発明は酸素富化空気供給装置、特に清浄化さ
れた酸素富化空気を提供する酸素富化空気供給装
置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oxygen-enriched air supply system, and more particularly to an oxygen-enriched air supply system that provides purified oxygen-enriched air.
人間が快適に生活し活動するためには、その周
囲に清浄化され所定量の酸素を含んだ空気が存在
することが必要である。従つて、人間の生活空間
内の空気が汚染された場合には、速かにその空気
を清浄にし必要な酸素を供給する必要がある。 In order for humans to live and work comfortably, it is necessary that clean air containing a predetermined amount of oxygen exists around them. Therefore, when the air in a human living space becomes contaminated, it is necessary to quickly purify the air and supply necessary oxygen.
特に、ある程度密閉された生活空間内において
はこの必要性が高く、例えば自動車による長距離
走行の場合に車室内への富化空気の供給が要望さ

（CO，CO2）を速かに除去し、かつ空気中の酸素
含有率を高めることが安全運転上及び快適なドラ
イバ環境を得る上でも必要である。 This is particularly necessary in a living space that is somewhat sealed, and for example, when driving a car over long distances, it is required to supply enriched air to the interior of the vehicle. This is because when a large number of people are inside a vehicle while the vehicle is being cooled and heated, carbon dioxide ( CO2) is released from exhaled air.
Carbon monoxide (CO) is generated in the air by smoking and
As a result, the content of oxygen in the air decreases,
This is because it promotes driver fatigue and causes sleepiness. Therefore, it is necessary to quickly remove harmful gases (CO, CO 2 ) from the air inside the vehicle and to increase the oxygen content in the air, both for safe driving and for providing a comfortable driver environment.
このため、従来、微細孔フイルタ、電気集塵、
活性炭フイルタ等による空調システムが開発され
商品化されており、車両内の汚れた空気の清浄化
をかなりの程度まで行なつている。 For this reason, conventional microporous filters, electrostatic precipitators,
Air conditioning systems using activated carbon filters and the like have been developed and commercialized, and are purifying the dirty air inside vehicles to a considerable extent.

高速道路走行中にあつては安全運転上の問題等の
２次的な諸問題を引きおこす原因となり、その改
良が求められていた。 However, such air conditioning systems cannot sufficiently remove carbon dioxide (CO) and carbon monoxide ( CO2 ) generated within the closed vehicle space, and due to their structure, the oxygen content in the air cannot be sufficiently removed. It was not possible to increase it. For this reason, the driver must open the windows to periodically replace the air inside the car, which increases the burden on air conditioning and causes problems for safe driving when driving on expressways. This caused the following problems, and improvements were needed.
また、このような車両用に限らず、他の方面か
らも、汚れた空気を速かに清浄にし必要な酸素を
供給することができる装置の開発が望まれてい

Equipped with an air blower that blows air under pressure, and a suction pump that sucks and permeates the air pressurized into the oxygen enricher through an oxygen enrichment membrane, the air is enriched with oxygen when the pressurized air is sucked and permeated. It is characterized by selectively permeating oxygen through a membrane to obtain oxygen-enriched air with a high oxygen content.

及び眠け防止を図ることができる。 Generally, an adult's exhaled breath contains 16.4% oxygen O2 and 4.1%
of carbon dioxide , and in a closed space such as a vehicle, the amount of carbon dioxide increases over time. There is a close relationship between the carbon dioxide concentration and the exposure time of humans; when the carbon dioxide concentration exceeds 2%, humans notice a slight change in perception within about 10 minutes, and when the carbon dioxide concentration exceeds 3%, humans notice a slight change in perception. After about 20 minutes, humans experience a level of discomfort that causes confusion.
If the carbon dioxide concentration exceeds 4%, you will begin to feel a confusing and uncomfortable feeling within about 6 or 7 minutes. Therefore, for safe driving, it is necessary to reduce the carbon dioxide concentration in the vehicle interior to within a certain value. For this purpose, if the oxygen-enriched air supply device of the present invention is used as an air conditioner for a vehicle, oxygen-enriched air with a high oxygen content can be supplied into the vehicle interior. In this way, by supplying air with a high oxygen content into the vehicle interior, it is possible to substantially reduce the carbon dioxide concentration, thereby recovering the driver's feeling of fatigue and preventing him from falling asleep.

考えることができるからである。 Note that the oxygen-enriched air of the present invention supplies oxygen-enriched air containing about 37% oxygen, so there may be a problem of oxygen poisoning. The danger of oxygen poisoning is almost negligible, so there is no practical problem. In other words, symptoms of oxygen poisoning appear after about 150 hours in air with an oxygen content of about 30%, and after 40 hours.
Symptoms only appear after about 60 hours in air with an oxygen content of about 50%. However, it is inconceivable that a driver would drive continuously for such a long period of time, and therefore it can be considered that there is almost no danger of oxygen poisoning.
