Description

【０００１】
【発明の属する技術分野】
本発明は室内空気中の煙草の臭気や建材、壁、家具から発生するアルデヒドなどの揮発性有機化合物、燃焼機などから発生する一酸化炭素などの無機ガスで代表される汚染ガスを焼却、分解して除去する空気清浄装置に関するものである。
【０００２】
【従来の技術】
従来よりこの種の機能を有する空気清浄装置としては、活性炭などの吸着材に空気中の臭い等の汚染ガスを吸着し除去するもの、また触媒やオゾンによって汚染ガスを分解する構成のものがあった。しかしながら、上記従来の脱臭フィルタを設けただけの空気清浄器では長時間使用すると脱臭フィルタの極細孔が臭い成分で塞がるため吸着脱臭能力が低下する。このため、一定期間ごとにフィルタの交換が必要であった。また、オゾン方式、触媒方式で連続的に汚染ガスを処理するには家庭用空気清浄装置であっても１ｍ3／分〜４ｍ3／分の処理風量が必要のため規模の大きな装置が必要であった。
【０００３】
また、吸着材を初期性能に再生する空気清浄装置として特開平３−２１３２３号公報に記載されている様なものが知られている。この装置は図９に示すように、臭気を含むガスを内部に吐出させるための吐出部を上部に有するダクト内に、上方から第１のヒータ、前記第１のヒーターにより加熱される熱分解触媒、吸着材、前記吸着材を加熱する第２のヒータ、およびファンを設置し、脱臭時には前記ファンを作動させ吸着材に臭気を吸着させ、前記吸着材の再生時には前記第１および第２のヒータに通電を行うとともに前記ファンを停止する構成とし、吸着材を加熱することで臭気を脱着させ、脱着した臭気ガスを加熱した熱分解触媒で分解し吸着材を初期状態に再生するものである。さらに再生時に臭気ガスが吐出部から臭気ガスが漏れるのを防ぐために、再生時に形状記憶合金ばねや風圧によって閉じるダンパを吐出部につけた構成が考案されている。

【発明が解決しようとする課題】
しかしながら、上記従来の脱臭フィルタを設けただけの空気清浄器では長時間使用すると脱臭フィルタの極細孔が臭い成分で塞がるため吸着脱臭能力が低下する。このため、一定期間ごとにフィルタの交換が必要であった。
【０００５】
また、オゾン方式、触媒方式で連続的に汚染ガスを処理するには家庭用空気清浄装置であっても１ｍ3／分〜４ｍ3／分の処理風量が必要のため規模の大きな装置が必要であった。
【０００６】
また、特開平３−２１３２３号公報のような方式では、図９に示すように、吐出部６が上部にあるため、第１のヒーター３および第２のヒーター５で発生した上昇気流が抵抗なく吐出部からダクト外に抜けるため、上昇気流による風量が大きくなり、熱分解触媒で脱着した臭気ガスが完全に分解しきれず、臭気ガスがダクト外に漏れる。臭気ガスの漏れを防止するには、吐出部の面積を小さくすれば良いが、脱臭時は圧力損失が大きくなり、ファン９の大型化や騒音の増大などの課題があった。
【０００７】
このため、再生時に形状記憶合金ばね８や風圧によって閉じるダンパ７を吐出部につけた構成が考案されている。しかし、ダンパー取り付けのため構成が複雑になることや、形状記憶合金ばね等でダンパーを開閉する構成では、外気温の変動等によって開閉が不安定になりやすく臭気ガスが漏れる、風圧ダンパーの構成ではヒーターからの熱でダンパーが昇温・熱膨張し動作が不安定になり臭気ガスが漏れるという課題があった。
【０００８】
【課題を解決するための手段】
本発明は上記課題を解決するために、吸込口と吹出口を持ち内部に浄化風路を有する本体と、前記浄化風路に空気を送風する送風手段と、浄化風路内に設けられた吸着手段と、吸着手段を加熱するように配置された加熱手段と、前記吸着手段上部に近接もしくは接触して配置された分解手段と、前記分解手段の上部に配置された通気口を持った滞留室を備え、前記通気口が前記滞留室天井面よりも下にあり、前記通気口に下向きの通気口ルーバーを設けた空気清浄装置とする。
【０００９】
上記発明によれば、部屋の空気に含まれる汚染ガスを除去する吸着モードの際は、送風手段のみを駆動し、本体外の空気を吸込口から通気口に導き、浄化風路内の分解手段、吸着手段の順に導き、吸着手段に吸着させる。吸着手段に所定量の汚染ガスが吸着すると、次に再生モードに入る。送風手段を停止した後、分解手段を駆動し、加熱手段を駆動することで汚染ガスは吸着手段から高温の汚染ガスとして脱着し、上昇気流となって分解手段である高温の電気発熱体や酸化分解触媒に接触し酸化され、揮発性有機化合物や一酸化炭素は水や二酸化炭素に分解される。分解後の水や二酸化炭素等のガスは上昇気流となって滞留室内を上昇し、滞留室天面から溜まっていき、順次押し出される形で下降し天面より下部に設けられた通気口から排気され、吸込口から部屋に排気される。このため、再生モードのほうが吸着モードの場合よりもガスが通過する流路が長く、送風抵抗が大きい。したがって再生モード、吸着モードとも同じ流路となる図９に示す従来例の構成のように、吸着モードの通気抵抗が同じ条件でも可動ダンパをつけなくても再生モードの流量を小さくすることができる。
【００１０】
【発明の実施の形態】
本発明は、吸込口と吹出口を持ち内部に浄化風路を有する本体と、前記浄化風路に空気を送風する送風手段と、浄化風路内に設けられた吸着手段と、吸着手段を加熱するように配置された加熱手段と、前記吸着手段上部に近接もしくは接触して配置された分解手段と、前記分解手段の上部に配置された通気口を持った滞留室を備え、前記通気口が前記滞留室天井面よりも下にあり、前記通気口に下向きの通気口ルーバーを設けた空気清浄装置とする。そして部屋の空気に含まれる汚染ガスを除去する吸着モードの際は、送風手段のみを駆動し、本体外の空気を吸込口から通気口に導き、浄化風路内の分解手段、吸着手段の順に導き、吸着手段に吸着させる。吸着手段に所定量の汚染ガスが吸着すると、次に再生モードに入る。送風手段を停止した後、分解手段を駆動し、加熱手段を駆動することで汚染ガスは吸着手段から高温の汚染ガスとして脱着し、上昇気流となって分解手段である高温の電気発熱体や酸化分解触媒に接触し酸化され、揮発性有機化合物や一酸化炭素は水や二酸化炭素に分解される。分解後の水や二酸化炭素等のガスは上昇気流となって滞留室内を上昇し、滞留室天面から溜まっていき、順次押し出される形で下降し天面より下部に設けられた通気口から排気され、吸込口から部屋に排気される。このため、再生モードのほうが吸着モードの場合よりもガスが通過する流路が長く、送風抵抗が大きい。したがって可動ダンパをつけなくても再生モードの流量を小さくすることができ、分解手段で脱離したガスを完全に分解することができる。
【００１１】
また、通気口に下向きの通気口ルーバを設けることにより、再生モードの場合、分解手段で分解後の水や二酸化炭素等のガスは通気口ルーバの上方から溜まっていき順次押し出される形で通気口ルーバ面に沿って下降し通気口ルーバ下部から排気され、吸込口から部屋に排気される。したがって吸着モードの通気抵抗が同じ条件で可動ダンパをつけなくても再生モードの流量をより小さくすることができ、分解手段の分解性能をより向上させることができる。
【００１２】
また、吸込口と吹出口を持ち内部に浄化風路を有する本体と、前記浄化風路に空気を送風する送風手段と、浄化風路内に設けられた吸着手段と、吸着手段を加熱するように配置された加熱手段と、前記吸着手段上部に近接もしくは接触して配置された分解手段と、前記分解手段の上部に配置された通気口を持った滞留室と、通気風路を備え、前記通気風路の一端が前記通気口に連通し他端が前記通気口よりも下にある構成では、再生モードの場合、分解手段で分解後の水や二酸化炭素等のガスは通気風路の上方から溜まっていき順次押し出される形で通気風路を下降し通気風路他端から排気され、吸込口から部屋に排気される。したがって、吸着モードの通気抵抗が同じ条件で可動ダンパをつけなくても再生モードの流量を小さくすることができ、分解手段で脱離したガスを完全に分解することができる。
【００１３】
また、上記構成において通気風路がノズル構造になっている場合、吸着モード時は汚染ガスを含んだ部屋の空気はノズルで滑らかに絞られノズル構造でない場合に比べて圧損が小さくなるとともに、再生モード時は分解手段で分解後の水や二酸化炭素等のガスは通気風路の上方から溜まっていき順次押し出される形で通気風路のノズル面を下降し通気風路他端から排気され、吸込口から部屋に排気される。したがって、吸着モードの通気抵抗が同じ条件で可動ダンパをつけなくてもノズル構造でない構成よりもさらに再生モードの流量を小さくすることができ、送風手段の小型化および分解手段の能力向上を実現できる。
【００１４】
また、通気風路途中に分離口が設けられ、分離口が浄化風路の吸着手段と分解手段の間に設けられた集合口に連通している構成では、再生モードの場合、分解手段通過後のガスは通気風路の上方から溜まっていき順次押し出される形で通気風路を下降し、通気風路他端から排気されるとともに、一部は集合口から再び分解手段に送られる。このため、一度に大量の脱離ガスが吸着手段から脱離し分解手段の処理能力を越え一部の未分解ガスが通気風路に漏れた場合においても、全量が通気風路他端から漏れるのを防止することができる。
【００１５】
また、分離口が集合口よりも下に設けられた構成では、再生モードで、吸着手段から脱離した汚染ガスは上昇気流となって上昇するため、集合口から分離口を通って通気風路に漏れることがないので、本体が多少傾いても再生時の汚染ガスの漏れがない。
【００１６】
また、滞留室内部に通気口より分解手段方向に空気の流れを変える変向ルーバーを設けたことを特徴とする構成では、吸着モードの場合通気口から滞留室に導かれた部屋の汚染ガスは変向ルーバで風向きを分解手段の方向へ滑らかに変えられ分解手段、吸着手段の順に導き、吸着手段に吸着させる。このため変向ルーバがない場合に比べて圧力損失を小さくすることができ、送風手段を小型化できる。
【００１７】
【実施例】
（実施例１）
図１は本発明の実施例１の要部切欠き斜視図であり、図２は図1の縦断面図である。
【００１８】
１０は吸込口１１と吹出口１２を持ち内部に浄化風路１３を有する本体であり、１４は浄化風路内１３に部屋内の空気中のホルムアルデヒドやトルエンなどの揮発性有機化合物からなる汚染ガスを選択的かつ発生量を十分に吸着するゼオライト等の吸着材でできた吸着手段であり、前記浄化風洞１３内には前記吸着手段１４を加熱して吸着した汚染ガスを脱着させる電気ヒータ等の加熱手段１５と、前記吸着手段１４から脱着した汚染ガスを分解する電気発熱体や酸化分解触媒からなる分解手段１６を吸着手段上部に近接もしくは接触して配置し、さらに、前記分解手段１６の上部には通気口１８が天井面よりも下に設けられた滞留室１７を設置し、前記浄化風路１３に空気を送風する送風手段１９によって前記吸着手段１４に汚染ガスを含む空気を送風する構成としたものである。
【００１９】
実施例１では、部屋の空気に含まれる汚染ガスを除去する吸着モードの際は、送風手段１９のみを駆動し、本体外の空気を吸込口１１から通気口１８に導き、浄化風路内１３の分解手段１６、吸着手段１４の順に導き、前記吸着手段１４に吸着させる。吸着モードでの空気の流れを破線矢印で示す。吸着手段１４に所定量の汚染ガスが吸着すると、次に再生モードに入る。前記送風手段１９を停止した後、分解手段１６を駆動し、加熱手段１５を駆動することで汚染ガスは吸着手段１４から高温の汚染ガスとして脱着し、上昇気流となって分解手段１６である高温の電気発熱体や酸化分解触媒に接触し酸化され、揮発性有機化合物や一酸化炭素は水や二酸化炭素に分解される。分解後の水や二酸化炭素等のガスは上昇気流となって滞留室内１７を上昇し、滞留室天面から溜まっていき、順次押し出される形で下降し天面より下部に設けられた通気口１８から排気され、吸込口１１から部屋に排気される。再生モードでの空気の流れを実線矢印で示す。このため、再生モードのほうが吸着モードの場合よりもガスが通過する流路が長く、送風抵抗が大きい。したがって再生モード、吸着モードとも同じ流路となる図９に示す従来例の構成のように、吸着モードの通気抵抗が同じ条件において可動ダンパをつけなくても再生モードの流量を小さくすることができ分解手段で脱離したガスを完全に分解することができる。

【００２１】
実施例１の構成に加え、通気口１８に下向きの通気口ルーバ２０を設けた点にある。本実施例においては、再生モードの場合、分解手段１６で分解後の水や二酸化炭素等のガスは通気口ルーバの上方から溜まっていき順次押し出される形で通気口ルーバ面に沿って下降し通気口ルーバ下部から排気され、吸込口から部屋に排気される。再生モードでの空気の流れを実線矢印で示す。したがって吸着モードの通気抵抗が同じ条件で可動ダンパをつけなくても再生モードの流量を小さくすることができ、分解手段の分解性能をより向上させることができる。

【００２３】
１０は吸込口１１と吹出口１２を持ち内部に浄化風路１３を有する本体であり、１４は浄化風路内１３に部屋内の空気中のホルムアルデヒドやトルエンなどの揮発性有機化合物からなる汚染ガスを選択的かつ発生量を十分に吸着するゼオライト等の吸着材でできた吸着手段であり、前記浄化風洞１３内には前記吸着手段１４を加熱して吸着した汚染ガスを脱着させる電気ヒータ等の加熱手段１５と、前記吸着手段１４から脱着した汚染ガスを分解する電気発熱体や酸化分解触媒からなる分解手段１６を吸着手段上部に近接もしくは接触して配置し、さらに、前記分解手段１６の上部には通気口１８が設けられた滞留室１７を設置し、前記通気口には一端２２が連通し、他端２３が前記通気口よりも下にある通気風路２１がつながっている。
【００２４】
そして前記浄化風路１３に空気を送風する送風手段１９によって前記吸着手段１４に汚染ガスを含む空気を送風する構成としたものである。
【００２５】
実施例３では、部屋の空気に含まれる汚染ガスを除去する吸着モードの際は、送風手段１９のみを駆動し、本体外の空気を吸込口１１から通気風路２１そして通気口１８に導き、浄化風路内１３の分解手段１６、吸着手段１４の順に導き、前記吸着手段１４に吸着させる。吸着モードでの空気の流れを破線矢印で示す。吸着手段１４に所定量の汚染ガスが吸着すると、次に再生モードに入る。前記送風手段１９を停止した後、分解手段１６を駆動し、加熱手段１５を駆動することで汚染ガスは吸着手段１４から高温の汚染ガスとして脱着し、上昇気流となって分解手段１６である高温の電気発熱体や酸化分解触媒に接触し酸化され、揮発性有機化合物や一酸化炭素は水や二酸化炭素に分解される。分解後の水や二酸化炭素等のガスは上昇気流となって滞留室内１７を上昇し、滞留室天面から溜まっていき、順次押し出される形で通気口１８から排気され、吸込口１１から通気風路２１に入り、通気風路を通って吸込口１１から部屋に排気される。再生モードでの空気の流れを実線矢印で示す。このため、再生モードのほうが吸着モードの場合よりもガスが通過する流路が長く、送風抵抗が大きい。したがって再生モード、吸着モードとも同じ流路となる図９に示す従来例の構成のように、吸着モードの通気抵抗が同じ条件において可動ダンパをつけなくても再生モードの流量を小さくすることができ分解手段で脱離したガスを完全に分解することができる。
【００２６】
（実施例４）
図５は、本発明の実施例４の断面図である。
【００２７】
実施例３と異なる点は、通気風路２１がノズル構造になっている場合、吸着モード時は汚染ガスを含んだ部屋の空気は通気風路２１のノズルで滑らかに絞られる。破線矢印に吸着モードの際の空気の流れを示す。本発明の構成では実施例３の構成比べて圧力損失が小さくなるとともに、再生モード時は分解手段１４で分解後の水や二酸化炭素等のガスは通気風路の上方から溜まっていき順次押し出される形で通気風路２１のノズル面を下降し通気風路他端２３から排気され、吸込口１１から部屋に排気される。したがって、吸着モードの通気抵抗が同じ条件で可動ダンパをつけなくてもノズル構造でない構成よりもさらに再生モードの流量を小さくすることができ、送風手段の小型化および分解手段の能力向上を実現できる。
【００２８】
（実施例５）
図６は、本発明の実施例５の断面図である。
【００２９】
実施例３の構成に加え、通気風路２１の途中に分離口２４が設けられ、前記分離口２４が浄化風路１３の吸着手段１４と分解手段１６の間に設けられた集合口２５に連通している事にある。本発明では吸着モードの場合、送風手段１９のみを駆動し、本体外の空気を吸込口１１から通気風路２１に導き、空気の一部は分離口２４と集合口２５を通って吸着手段１４に導くとともに、残りの空気は浄化風路内１３の分解手段１６、吸着手段１４の順に導き、前記吸着手段１４に吸着させる。吸着モードでの空気の流れを破線矢印で示す。したがって吸着モードの場合、実施例３に示す構成よりも圧力損失を小さくすることができ、ファン等の送風手段１９の小型化が図れる。また再生モードの場合、分解手段１６通過後のガスは通気風路２１の上方から溜まっていき順次押し出される形で通気風路を下降し、通気風路２１他端２３から排気され、吸込口１１から部屋へ排気されるとともに、一部は分離口２４および集合口２５を通って再び分解手段１４に送られる。再生モードの空気の流れを実線矢印で示す。このため、一度に大量の脱離ガスが吸着手段１４から脱離し分解手段１６の処理能力を越え一部の未分解ガスが通気風路２１に漏れた場合においても、全量が吸込口１１から漏れるのを防止することができる。
【００３０】
（実施例６）
図７は、本発明の実施例６の断面図である。
【００３１】
実施例５と異なる点は、分離口２４が集合口２５よりも下に設けられていることにある。本発明において再生モードでは、吸着手段１４から脱離した汚染ガスは上昇気流となって上昇するため、本体が多少傾いていても集合口２５から分離口２４を通って通気風路２１に漏れることなく分解手段１６に導かれ分解手段である高温の電気発熱体や酸化分解触媒に接触し酸化され、揮発性有機化合物や一酸化炭素は水や二酸化炭素に分解される。分解手段１６通過後のガスは通気風路２１の上方から溜まっていき順次押し出される形で通気風路を下降し、通気風路２１他端２３から排気され、吸込口１１から部屋へ排気されるとともに、一部は分離口２４および集合口２５を通って再び分解手段１４に送られる。再生モードの空気の流れを実線矢印で示す。このため、一度に大量の脱離ガスが吸着手段１４から脱離し分解手段１６の処理能力を越え一部の未分解ガスが通気風路２１に漏れた場合においても、全量が吸込口１１から漏れるのを防止することができる。
【００３２】
（実施例７）
図８は、本発明の実施例７の断面図である。
【００３３】
本発明は、実施例１の構成に加え、滞留室１７内部に、通気口１８より分解手段１６方向に空気の流れを変える変向ルーバー２６を設けた構成となっている。吸着モードの場合、通気口１８から滞留室１７に導かれた部屋の汚染ガスは変向ルーバ２６で風向きを分解手段１６の方向へ滑らかに変えられ分解手段１６、吸着手段１４の順に導き、吸着手段１４に吸着させる。吸着モードの空気の流れを破線矢印に示す。このため実施例１の構成に比べ、圧力損失を小さくすることができ、送風手段１９を小型化できる。なお、再生モードでは、分解手段１６を通過した、分解後の水や二酸化炭素等のガスは上昇気流となって滞留室１７内を上昇し、滞留室１７天面から溜まっていき、順次押し出される形で下降し天面より下部に設けられた通気口１８から排気され、吸込口１３から部屋に排気される。
【００３４】
したがって可動ダンパをつけなくても再生モードの流量を小さくすることができ、分解手段の分解性能をより向上させることができる。
【００３５】

【００３７】
（２）滞留室の通気口に下向きの通気口ルーバを設けたことを特徴とする構成においては、再生モードの際に自然対流によるガスの流れの送風抵抗をさらに大きくし、可動ダンパをつけなくても再生モードの流量を小さくすることができ、分解手段で脱離したガスをより完全に分解することができる空気清浄装置を実現できる。

BACKGROUND OF THE INVENTION
The present invention incinerates and decomposes odors of cigarettes in indoor air, volatile organic compounds such as aldehyde generated from building materials, walls, furniture, and inorganic gases such as carbon monoxide generated from combustors. It is related with the air purifying apparatus removed by doing.
[0002]
[Prior art]
Conventionally, air purifiers having this type of function include those that adsorb and remove pollutant gases such as odors in the air on adsorbents such as activated carbon, and those that decompose pollutant gases with catalysts and ozone. It was. However, in the case of using the above-mentioned conventional air purifier with only the deodorizing filter, the adsorption / deodorizing ability is lowered because the pores of the deodorizing filter are blocked with odorous components when used for a long time. For this reason, it is necessary to replace the filter at regular intervals. Moreover, in order to continuously treat polluted gases using ozone and catalyst systems, a large-scale device is required because a processing air volume of 1 m3 / min to 4 m3 / min is required even for a domestic air purifier. .
[0003]
In addition, as an air cleaning device for regenerating the adsorbent to the initial performance, a device as described in JP-A-3-21323 is known. As shown in FIG. 9, this apparatus has a first heater and a pyrolysis catalyst heated by the first heater from above in a duct having a discharge section for discharging a gas containing odor inside. An adsorbent, a second heater for heating the adsorbent, and a fan are installed to operate the fan during deodorization to adsorb odor to the adsorbent, and to regenerate the adsorbent, the first and second heaters The odor is desorbed by heating the adsorbent and the desorbed odor gas is decomposed by a heated thermal decomposition catalyst to regenerate the adsorbent to the initial state. Further, in order to prevent the odor gas from leaking from the discharge portion during regeneration, a configuration has been devised in which a damper that is closed by a shape memory alloy spring or wind pressure at the time of regeneration is attached to the discharge portion.
[0004]
[Problems to be solved by the invention]
However, in the case of using the above-mentioned conventional air purifier with only the deodorizing filter, the adsorption / deodorizing ability is lowered because the pores of the deodorizing filter are blocked with odorous components when used for a long time. For this reason, it is necessary to replace the filter at regular intervals.
[0005]
Moreover, in order to continuously treat polluted gases using ozone and catalyst systems, a large-scale device is required because a processing air volume of 1 m3 / min to 4 m3 / min is required even for a domestic air purifier. .
[0006]
Further, in the system as disclosed in Japanese Patent Laid-Open No. 3-21323, as shown in FIG. 9, since the discharge unit 6 is at the upper part, the ascending airflow generated in the first heater 3 and the second heater 5 has no resistance. Since the air flows out of the duct from the discharge part, the air volume due to the rising air flow increases, and the odor gas desorbed by the thermal decomposition catalyst cannot be completely decomposed, and the odor gas leaks out of the duct. In order to prevent leakage of odorous gas, the area of the discharge portion may be reduced. However, pressure loss increases during deodorization, and there are problems such as an increase in the size of the fan 9 and an increase in noise.
[0007]
For this reason, a configuration has been devised in which a shape memory alloy spring 8 and a damper 7 that is closed by wind pressure at the time of regeneration are attached to the discharge part. However, because the configuration is complicated due to the installation of the damper, or when the damper is opened and closed with a shape memory alloy spring or the like, the opening and closing tends to become unstable due to fluctuations in the outside temperature, etc., and odor gas leaks. There was a problem that the damper heated up and thermally expanded due to the heat from the heater, resulting in unstable operation and odor gas leaking.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has a main body having a suction port and a blower outlet and having a purification air passage inside, a blowing means for blowing air into the purification air passage, and an adsorption provided in the purification air passage. A retention chamber having a means, a heating means arranged to heat the adsorption means, a decomposition means arranged close to or in contact with the upper part of the adsorption means, and a vent arranged above the decomposition means And the air vent is located below the ceiling surface of the retention chamber, and the air vent is provided with a downward vent louver .

The present invention includes a main body having a suction port and a blower outlet and having a purification air passage inside, a blower means for blowing air to the purification air passage, an adsorption means provided in the purification air passage, and heating the adsorption means Heating means arranged so as to dispose, decomposition means arranged close to or in contact with the upper part of the adsorption means, and a residence chamber having an air vent arranged on the upper part of the decomposition means, The air purifier is located below the ceiling surface of the retention chamber and has a downward vent louver at the vent . And in the adsorption mode to remove the pollutant gas contained in the room air, only the air blowing means is driven, the air outside the main body is led from the suction port to the ventilation port, the decomposition means in the purification air passage, the adsorption means in this order Guide and adsorb to adsorption means. When a predetermined amount of contaminated gas is adsorbed on the adsorbing means, the regeneration mode is entered next. After stopping the air blowing means, the decomposition means is driven, and the heating means is driven, so that the pollutant gas is desorbed from the adsorption means as a high-temperature pollutant gas and becomes an ascending air current, which is a high-temperature electric heating element or oxide Oxidized by contact with the decomposition catalyst, volatile organic compounds and carbon monoxide are decomposed into water and carbon dioxide. After decomposition, gas such as water and carbon dioxide rises into the residence chamber, rises from the top of the residence chamber, accumulates from the top of the residence chamber, descends in a push-out manner, and exhausts from a vent provided below the top surface. And exhausted from the suction port to the room. For this reason, the flow path through which gas passes is longer in the regeneration mode than in the adsorption mode, and the blowing resistance is larger. Therefore, the flow rate in the regeneration mode can be reduced without attaching a movable damper, and the gas desorbed by the decomposition means can be completely decomposed.
[0011]
Further, by kicking setting a downward vent louvers vents, if the playback mode, gas water and carbon dioxide after the decomposition by the decomposition means in the form of sequentially pushed gradually accumulated from above the vent louver It descends along the vent louver surface, exhausts from the lower part of the vent louver, and exhausts from the suction port to the room.

[0012]
A main body having a suction port and a blower outlet and having a purification air passage inside; a blowing means for blowing air into the purification air passage; an adsorption means provided in the purification air passage; and heating the adsorption means A heating means arranged in the above, a decomposition means arranged close to or in contact with the upper part of the adsorption means, a staying chamber having a vent arranged in the upper part of the decomposition means, and a ventilation air passage, In the configuration in which one end of the ventilation air passage communicates with the air vent and the other end is below the air vent, in the regeneration mode, water such as water and carbon dioxide after decomposition by the decomposition means is above the ventilation air passage. From the other end of the ventilation air passage, it is exhausted from the other end of the ventilation air passage and exhausted into the room. Therefore, the flow rate in the regeneration mode can be reduced without attaching a movable damper under the same adsorption resistance in the adsorption mode, and the gas desorbed by the decomposing means can be completely decomposed.
[0013]
Also, in the above configuration, when the ventilation air passage has a nozzle structure, the air in the room containing the pollutant gas is smoothly squeezed by the nozzle in the adsorption mode, and the pressure loss is smaller than that in the case where the nozzle structure is not used. In the mode, water such as water and carbon dioxide after being decomposed by the decomposition means accumulates from above the ventilation air passage and is sequentially pushed out, descends the nozzle surface of the ventilation air passage and is exhausted from the other end of the ventilation air passage. It is exhausted from the mouth to the room. Accordingly, the flow rate in the regeneration mode can be further reduced as compared with the configuration without the nozzle structure even if the movable damper is not attached under the same conditions of the suction resistance in the suction mode, and the downsizing of the blowing means and the improvement of the ability of the disassembling means can be realized. .
[0014]
Further, in a configuration in which a separation port is provided in the middle of the ventilation air passage and the separation port communicates with a collecting port provided between the adsorption means and the decomposition means of the purification air passage, in the regeneration mode, after the passage of the decomposition means The gas accumulates from above the ventilation air passage and descends in the form of being sequentially pushed out, exhausted from the other end of the ventilation air passage, and partly sent again to the disassembling means from the collecting port. For this reason, even if a large amount of desorbed gas is desorbed from the adsorbing means at a time and exceeds the processing capacity of the decomposing means, and part of the undecomposed gas leaks into the ventilation air passage, the entire amount leaks from the other end of the ventilation air passage. Can be prevented.
[0015]
Further, in the configuration in which the separation port is provided below the collection port, in the regeneration mode, the polluted gas desorbed from the adsorption means rises as an updraft, so the ventilation air passage from the collection port through the separation port Therefore, even if the main body is tilted slightly, there is no leakage of contaminated gas during regeneration.
[0016]
Further, in the configuration characterized in that a direction changing louver that changes the flow of air from the vent in the direction of the decomposition means is provided in the stay chamber, in the adsorption mode, the pollutant gas in the room led from the vent to the stay chamber is The direction of the wind is smoothly changed in the direction of the disassembling means by the turning louver, and the disassembling means and the adsorbing means are guided in this order and adsorbed by the adsorbing means. For this reason, pressure loss can be made small compared with the case where there is no turning louver, and a ventilation means can be reduced in size.

[0025]
In Example 3, in the adsorption mode for removing pollutant gas contained in room air, only the air blowing means 19 is driven, and air outside the main body is guided from the suction port 11 to the ventilation air passage 21 and the ventilation port 18. The decomposing means 16 and the adsorbing means 14 in the purification air passage 13 are led in this order and adsorbed by the adsorbing means 14. The flow of air in the adsorption mode is indicated by broken line arrows. When a predetermined amount of contaminated gas is adsorbed on the adsorbing means 14, the regeneration mode is entered next. After stopping the blowing means 19, the decomposition means 16 is driven, and the heating means 15 is driven so that the pollutant gas is desorbed from the adsorption means 14 as a high-temperature pollutant gas and becomes an ascending air current.

The difference from the third embodiment is that when the ventilation air passage 21 has a nozzle structure, the air in the room containing the contaminated gas is smoothly throttled by the nozzle of the ventilation air passage 21 in the adsorption mode. The broken line arrow shows the air flow during the adsorption mode. In the configuration of the present invention, the pressure loss is smaller than in the configuration of the third embodiment, and in the regeneration mode, the gas such as water and carbon dioxide after decomposition is accumulated from above the ventilation air passage and sequentially pushed out by the decomposition means 14. In this manner, the nozzle surface of the ventilation air passage 21 is lowered, exhausted from the other end 23 of the ventilation air passage, and exhausted to the room from the suction port 11. Accordingly, the flow rate in the regeneration mode can be further reduced as compared with the configuration without the nozzle structure even if the movable damper is not attached under the same conditions of the suction resistance in the suction mode, and the downsizing of the blowing means and the improvement of the ability of the disassembling means can be realized. .

[0029]
In addition to the configuration of the third embodiment, a separation port 24 is provided in the middle of the ventilation air passage 21, and the separation port 24 communicates with a collecting port 25 provided between the adsorption means 14 and the decomposition means 16 of the purification air passage 13. There is in doing. In the present invention, in the adsorption mode, only the air blowing means 19 is driven, air outside the main body is guided from the suction port 11 to the ventilation air passage 21, and a part of the air passes through the separation port 24 and the collecting port 25, and the adsorption means 14. The remaining air is led in the order of the disassembling means 16 and the adsorbing means 14 in the purification air passage 13 and is adsorbed by the adsorbing means 14. The flow of air in the adsorption mode is indicated by broken line arrows. Therefore, in the case of the adsorption mode, the pressure loss can be reduced as compared with the configuration shown in the third embodiment, and the blower 19 such as a fan can be downsized. In the regeneration mode, the gas that has passed through the decomposition means 16 accumulates from above the ventilation air passage 21, descends in the ventilation air passage while being sequentially pushed out, and is exhausted from the other end 23 of the ventilation air passage 21. As a result, the air is exhausted to the room and part thereof is sent again to the disassembling means 14 through the separation port 24 and the collecting port 25. The air flow in the regeneration mode is indicated by solid arrows. For this reason, even when a large amount of desorbed gas is desorbed from the adsorbing means 14 at one time and exceeds the processing capacity of the decomposing means 16, and a part of the undecomposed gas leaks into the ventilation air passage 21, the entire amount leaks from the inlet 11.

[0031]
The difference from the fifth embodiment is that the separation port 24 is provided below the assembly port 25. In the present invention, in the regeneration mode, the polluted gas desorbed from the adsorbing means 14 rises as an updraft, and therefore leaks from the collecting port 25 through the separation port 24 to the ventilation air passage 21 even if the main body is slightly inclined. Without being led to the decomposition means 16, the decomposition means comes into contact with a high-temperature electric heating element or oxidative decomposition catalyst and is oxidized, and volatile organic compounds and carbon monoxide are decomposed into water and carbon dioxide. The gas after passing through the decomposing means 16 accumulates from above the ventilation air passage 21 and descends in the form of being sequentially pushed out, exhausted from the other end 23 of the ventilation air passage 21, and exhausted from the suction port 11 to the room. At the same time, a part is sent again to the disassembling means 14 through the separation port 24 and the collecting port 25. The air flow in the regeneration mode is indicated by solid arrows. For this reason, even when a large amount of desorbed gas is desorbed from the adsorbing means 14 at one time and exceeds the processing capacity of the decomposing means 16, and a part of the undecomposed gas leaks into the ventilation air passage 21, the entire amount leaks from the inlet 11. Can be prevented.

In addition to the configuration of the first embodiment, the present invention has a configuration in which a turning louver 26 that changes the air flow from the vent 18 toward the disassembling means 16 is provided inside the stay chamber 17. In the case of the adsorption mode, the pollutant gas in the room led from the vent 18 to the staying chamber 17 is smoothly changed in the direction of the decomposition means 16 by the direction change louver 26 and guided to the decomposition means 16 and the adsorption means 14 in this order. Adsorbed on the means 14. The air flow in the adsorption mode is indicated by a broken-line arrow. For this reason, compared with the structure of Example 1, pressure loss can be made small and the ventilation means 19 can be reduced in size. In the regeneration mode, the decomposed gas such as water and carbon dioxide that has passed through the decomposition means 16 becomes an ascending current, rises in the retention chamber 17, accumulates from the top of the retention chamber 17, and is sequentially pushed out. Then, the air is exhausted from the vent 18 provided below the top surface and exhausted from the suction port 13 to the room.
