本発明は自動車等の車両に搭載され車室内の空気を浄化
する車両用空気清浄器に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle air cleaner that is mounted on a vehicle such as an automobile and purifies the air inside the vehicle.
従来、自動車等の車両に搭載される車両用空調装置にお
いては、車室外からの外気を取り入れて、冷房あるいは
暖房する場合と、車室内の内気を循環して、冷暖房する
方法がある。この内、外気の場合は空気の入替えがある
ため、熱効率は悪い。BACKGROUND ART Conventionally, in vehicle air conditioners installed in vehicles such as automobiles, there are two methods: one method is to take in outside air from outside the vehicle interior for cooling or heating, and the other method is to circulate the inside air inside the vehicle interior for heating and cooling. Of these, in the case of outside air, the thermal efficiency is poor because the air must be exchanged.
一方、内気の場合は、空気の出入りがないため、熱効率
は良いが、車室内の臭気、粉塵等の不快成分やＣ０１Ｎ
ｏ、、Ｓｏ、等の有害成分が排除されないため、内気状
態を長時間続けることには問題があった。On the other hand, in the case of inside air, the thermal efficiency is good because there is no air going in and out.
Since harmful components such as O, So, etc. are not eliminated, there is a problem in continuing the indoor air condition for a long time.
また、脱臭、集塵のための空気清浄器が使われるが、臭
い、粉塵は除去されるものの、タバコ等から排出される
Ｃ０１ＮＯＸ、ＳＯＸに対しては効果がなく、これらの
成分を除去しない限り、内気状態での空調継続の問題は
解決されない。Additionally, air purifiers are used to deodorize and collect dust, but although they remove odors and dust, they are ineffective against CO1NOX and SOX emitted from cigarettes, etc., unless these components are removed. , the problem of continuous air conditioning in indoor air conditions remains unsolved.
さらに、一般に使用されている空気清浄器では、活性炭
などの吸着材が用いられているが、これらの吸着材では
、臭い成分の吸着量が飽和に達すれば寿命がつき、交換
しなければならない。Furthermore, commonly used air purifiers use adsorbents such as activated carbon, but these adsorbents reach the end of their lifespan when the amount of odor components adsorbed reaches saturation, and must be replaced.
また、最近、光励起触媒を利用した空気浄化装置（特開
昭６３−８０８３３号公報）も利用されているが、これ
も前記吸着材を用いた空気清浄器より寿命が長いという
利点があるが、酸化反応により、Ｃ０１ＮＯｘ等を排出
するため、内気状態での空調継続の問題は解決されない
。Recently, an air purifier using a photoexcited catalyst (Japanese Patent Application Laid-open No. 63-80833) has also been used, but this also has the advantage of having a longer lifespan than the air purifier using the adsorbent. Since CO1NOx and the like are discharged due to the oxidation reaction, the problem of continuing air conditioning in indoor air conditions is not solved.
本発明は上記事実を考慮し、臭い、粉塵等の不快成分と
、Ｃ０１ＮＯＸ等の有害成分との双方を一括して除去で
き、内気状態で冷暖房の連続運転を可能とすることがで
きる車両用空気清浄器を提供することが目的である。Taking the above facts into consideration, the present invention provides air for vehicles that can simultaneously remove both unpleasant components such as odors and dust, and harmful components such as CO1NOx, and that allows continuous operation of air conditioning and heating in indoor air conditions. The purpose is to provide a purifier.

A part of the air from which dust and odor components have been removed is sucked in by the first blowing means operated by the control means, and when the first flow rate adjustment means is opened by the control means, it is transferred to the separation tube filled with adsorbent. be introduced. The air introduced into the separation tube is N2.0□ and CO
5NOx etc. are separated. That is, in the separation tube, N2.
0□ flows faster than C01No, etc., and C01NOx, etc. lags behind due to its affinity with the adsorbent. Therefore, when most of the N2.0□ has flowed out from the outlet of the separation tube, the control means causes the air sucked in by the second blowing means to flow back into the separation tube by flattening the third flow rate adjustment means, The first flow rate adjustment means is closed and the second flow rate adjustment means is opened to discharge Co, NOx, etc. from the exhaust pipe to the outside of the vehicle. By repeating this process, unpleasant components such as odor, Co, and N are removed.
