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 means that when there are many people inside the vehicle while heating and cooling the vehicle, the amount of carbon dioxide from exhalation is 000! This is because carbon monoxide (CO) caused by smoking and carbon monoxide generates internal air pressure, and the oxygen content in the air decreases by that amount, accelerating driver fatigue and causing drowsiness. Therefore, toxic gases (c) are removed from the air inside the vehicle.
It is necessary to quickly remove O, Co, ) and increase the oxygen content in the air for safe driving and for obtaining a comfortable driving environment.

的に二酸化炭素濃度を低下せしめドライバの疲労感の回
復及び眠は防止を図ることができる。There is a close relationship between this carbon dioxide concentration and the exposure time of humans.When the carbon dioxide concentration exceeds 2-2, humans notice a slight change in perception within about 10 minutes, and when the carbon dioxide concentration exceeds 3%. After about 20 minutes, humans experience a level of discomfort that confuses their feelings. When the carbon dioxide concentration exceeds 4%, it takes about 6 or 7 minutes for the body to become uncomfortable and cause confusion. Therefore, for safe driving, it is necessary to reduce the carbon dioxide concentration in the vehicle interior to within a certain value. To achieve this objective, 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.

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, but the oxygen content of the air is 40% at 1 atm.
To a certain extent, the danger of oxygen poisoning can be ignored, so in practice: there is no problem. In other words, oxygen poisoning is 3
Symptoms appear after about 150 hours in air with an oxygen content of about 40%, and 6 hours in air with an oxygen content of about 40%.
Symptoms only appear at about 0 hours. However, it is unthinkable for drivers to drive continuously for such long periods of time.
Therefore, it can be considered that there is no danger of oxygen poisoning.

Although the oxygen-enriched air supply device has a structure in which pressurized air is sucked and permeated from outside the pipe line of the oxygen-enriched membrane using a suction pump, the device is not limited to this, and can be used, for example, in an oxygen enricher. The oxygen enriched membrane is formed into a thin tube shape, and the air taken in from the inlet using a blower is blown under pressure to the outer circumference of the oxygen enriched membrane pipe, and the pressurized air is enriched with oxygen. As explained above, according to the present invention, oxygen is preferentially permeated from the air, and toxic gases are selectively permeated. It becomes possible to obtain oxygen-enriched air with a high oxygen content separated by using a small and simple device.
