Description

【０００１】
【発明の属する技術分野】
本発明は、座席のように人体を保持し、空調する機能を持った装置に関するもので、例えば除湿装置を備えた自動車用座席、オフィス用椅子、座椅子、寝椅子、ベッド、布団などとして利用される。
【０００２】
【従来の技術】
従来のこの種の空調座席装置として第一の従来例では以下に示す構成が開示されている（例えば特許文献１参照）。第一の従来例に示す図１７に示すようにシート本体１の人体背面部が当接する部分に相当する部分の表皮クロス２を通して外気を強制的に吸気する空気袋３を前記シート本体１に内蔵し、且つ前記空気袋３が吸気した外気を除湿乾燥して前記空気袋３を通して人体背面部に排気する冷却除湿器４と加熱乾燥器５からなる除湿乾燥装置６をヘッドレストに内蔵して前記除湿乾燥装置６と空気袋３を吸気通気路７、排気通気路８で連通させた構成になっている。
【０００３】
上記構成において、人体背面の外気（３２℃、湿度８０％）は表皮クロス２を通して空気袋３に吸気され、吸気通気路７を通して冷却除湿器４に入り冷却除湿（結露）された空気（１５℃、１００％）となり、加熱乾燥器５に送られ加熱乾燥された空気（３０℃、５０％）となり、排気通気路８を通して空気袋３に入り、表皮クロス２から人体背面部に向けて吹出させ、冷却風による体温の奪われを防止しつつ蒸れ発生を防止するものである。
【０００４】
しかし、上記従来の構成では、除湿において冷却除湿器４で除湿を行うため、結露水を流すための排水管（図示せず）が必要になり、自動車用本体などでは特別な加工が必要であり、また移動可能なオフィス用椅子としては簡単に使用できない。
【０００５】
また、吸湿材料を使用した第二の従来例の空調座席装置が以下のように開示されている（例えば特許文献２）。すなわち第二の従来例の図１８、図１９、図２０に示すように、背もたれ部９は内部に空気通路１０を有しており、背もたれ部９と空気通路１０の間には水蒸気分圧の勾配にしたがった非通気性と透湿性を併せ持った透湿層１１が配置されており、空気通路１０には背もたれ部９から透湿してくる水蒸気が流れ込む。そして吸湿性材料を備えた空気乾燥装置１２を通して乾燥させた空気を空気通路１０に流すことで透湿層１１が背もたれ部９外側にある水蒸気が透過し、そして水蒸気は乾燥した空気中で蒸発する。
【０００６】
なお、空気乾燥装置１２は、図１９に示すように、１５、１６は空気入口を持ったゼオライトやシリカゲルのような吸着材料１７、１８で満たされた反応容器であり、それぞれ一体化された電気ヒーター２１、２２を有し、電気駆動される空気フラップ１４で空気通路１０の入口と接続されている通路出口２０、および車室に開口した車内出口１９に流路が切り替えられるようになっている。
【０００７】
上記構成において、空気乾燥装置１２を連続運転するために２つの反応容器１５、１６は交互に吸湿プロセス、ならびに再生プロセスと切り替えられる。一方の反応容器１５内の吸着材料１７が電気ヒーター２１で再生されている時（再生プロセス）、他の反応容器１６がその内部を流れる空気を吸着材料１８の吸湿作用によって乾燥させるとともに、吸着熱で空気を加熱する（吸湿プロセス）。反応容器１６の吸着材料１８が飽和すると、空気フラップ１４を破線のように切り替え電気ヒーター２２を通電し反応容器１６内の吸着材料１８を再生するとともに反応容器１５がその内部を流れる空気を吸着材料１７の吸湿作用によって乾燥させる。また図２０に示すように、ファン２３を車内出口１９近傍に配設してもよい。
【０００８】
しかし、上記従来の構成では、人体で発生した汗は椅子と接した場所以外は吸収されず、また、衣類と透湿層１１を通して水分を吸収するために、汗の吸収量が少ないものであった。また空気乾燥装置１２を出た空気は吸着熱で温度が高くなっているため、そのまま背もたれ部９から吹出しても冷涼感は得られない。
【０００９】
また、吸着材を用いて連続的に吸着再生を行う第三の従来例として、以下の内容が開示されている（例えば特許文献３参照）。この図２１に示すように、コルゲートまたはハニカム形状に成型された円筒状の吸着材２４が知られており、空気の湿度を調節する調湿装置等に利用されている。吸着材２４はタイミングベルト２５を介して駆動モーター２６でゆっくり回転しており、再生ファン２７によって送られた空気は再生用加熱ヒーター２８で高温に加熱された吸着材２４に送られ、吸着材２４に吸着していた水分を脱着し、湿り空気２９ａとして排出される。そして水分を放出し再生した吸着材２４は回転し送風ファン３０によって供給された高湿空気を、吸着材２４が再生した位置に送風し、吸着材２４内へ導入されて水蒸気が吸着され、乾燥空気２９ｂとして排出される構成となっており、連続して高湿空気の除湿を行うことができるものである。
【００１０】
しかし、上記従来の構成では、水分を脱着し再生している部位の吸着材２４の熱が、除湿している部位に伝わるので乾燥空気２９ｂの温度が高くなり、乾燥空気２９ｂによって、冷涼感を得るような装置には不適である。また、加熱ヒーター２８で高温に加熱した空気によって間接的に吸着材２４を加熱する構成のため、吸着材２４の加熱効率が低く、消費電力が大きい。また、吸着材２４に伝わらなかった熱は高温の湿り空気として大量に排出されるため室内の温度が上昇し、冷涼感を得るような装置には不適である。さらに風路が複雑であり、吸着材２４を回転させる構成が必要であり、吸着材２４も大きくなるので装置の小型化が難しかった。

【発明が解決しようとする課題】
しかしながら、前記従来の装置では、２つの反応容器が交互に吸湿プロセス、ならびに再生プロセスと交互に切り替えられることによって、連続運転を可能としていた。この場合、２つの反応容器が必要となり、装置の大型化、部品点数の増加、コストの増加となってしまう。
【００１３】
また、コルゲートまたはハニカム形状に成型された円筒状の吸着材を回転させて除湿運転と吸着材の再生を行うローター式の場合では、水分を脱着している部位の吸着材熱が、除湿している部位に伝わるので乾燥空気温度が高くなり、乾燥空気によって、冷涼感を得るような装置には不適である。また、加熱ヒーターで高温に加熱した空気によって間接的に吸着材を加熱する構成のため、吸着材の加熱効率が低く、消費電力が大きいとともに、再生時間が長くかかってしまう。
【００１４】
また、吸着材に伝わらなかった熱は高温の湿り空気として大量に排出されるため室内の温度が上昇するので、冷涼感を得るような装置には不適である。また、吸着材に伝わらなかった熱量の分だけ吸着材の再生乾燥が不充分となるため、吸着効率の低い装置となってしまう。さらに風路が複雑であり、吸着材を回転させる構成が必要であり、吸着材も大きくなるので装置の小型化が難しい。さらに、連続的に吸着運転と再生運転を行うために、一般的には乾燥空気送風用の送風機と吸着材再生用の送風機の２つの送風機が必要となるので、装置が大型となり、部品点数が増し、コストを増加させるという課題を有していた。
【００１５】
本発明は、前記従来の課題を解決するもので、ダンパー（フラップ）や吸着材の駆動機構が無い簡単な構成で、再生−吸着の連続運転が可能な、吸着材結露水の処理が必要なく、車内の室温が高くても人体の体感温度が低く感じられる空調座席装置の実現を目的としたものである。さらに、加熱効率が高く除湿材料の再生時間の早い小型の空調座席装置の実現を目的としたものである。
【００１６】
【課題を解決するための手段】
前記従来の課題を解決するために、本発明の空調座席装置は、車室内空気を送風するシロッコファン等の送風機と、前記送風機の吹出口に吸込口を近接させて設置したシロッコファン等の再生送風機と、前記送風機と前記除湿手段を結ぶ送風路と、前記送風機で送風された空気をシリカゲルや活性アルミナなどの吸着材で除湿する除湿手段と、除湿後の空気を室内空気で冷却する熱交換器と、除湿手段を加熱させる加熱手段と、座席本体の表皮に設けられた空気を噴出する噴出口と、前記熱交換器で熱交換後の乾燥空気を噴出口に導く通風路とからなるものである。
【００１７】
上記構成において、吸着材の能力を再生させる再生モードでは送風機を停止し、加熱手段と、再生送風機を駆動させる。加熱手段で除湿手段が加熱されると、除湿手段に吸着されていた水蒸気は脱離する。脱離した水蒸気は、再生送風機によって再生送風機の吹出口から、本体外へ排出される。
【００１８】
次に噴出口から乾燥空気を噴出し人体に送風する除湿モードでは、加熱手段と再生送風機を停止し、送風機を駆動する。送風機吹出口と、再生送風機吸込口は近接して設置されているので、送風機吹出口から送風された送風流によって、再生手段の吸込口から空気が誘引されて流出し、送風流は除湿手段に入り、空気流は除湿手段で除湿されて、熱交換器によって冷却される。送風機によって０．２m³／分の流量で除湿手段に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は吸着材で水蒸気を吸着され湿度が低下するとともに吸着熱で発熱し（６５℃、３％ＲＨ）の空気となる。高温低湿度の空気は熱交換器に導かれ車室空気で冷却され（３７℃、２０％）の低湿度空気となって通風路に導かれ表皮の噴出口から吹き出し、人体背側面を流れる。その際体表面の汗を気化させることで気化熱をうばい人体に冷涼感を与えるとともに、ムレ感をも防止する。
【００１９】
また、送風機の吹出口に吸込口を近接させて設置してあるので、ダンパー等で再生送風機の吸込口を塞がなくても、送風機の送風流によって、再生送風機から空気が誘引され、送風流が再生送風機から逆流して本体外へ流出することを防止できる。
【００２０】
【発明の実施の形態】
請求項１に記載の発明は、車室内空気を送風するシロッコファン等の送風機と、前記送風機の吹出口に吸込口を近接させて設置したシロッコファン等の再生送風機と、前記送風機と前記除湿手段を結ぶ送風路と、前記送風機で送風された空気をシリカゲルや活性アルミナなどの吸着材で除湿する除湿手段と、除湿後の空気を室内空気で冷却する熱交換器と、除湿手段を加熱させる加熱手段と、座席本体の表皮に設けられた空気を噴出する噴出口と、前記熱交換器で熱交換後の乾燥空気を噴出口に導く通風路とからなるものである。
【００２１】
上記構成において、吸着材の能力を再生させる再生モードでは送風機を停止し、加熱手段と、再生送風機を駆動させる。加熱手段で除湿手段が加熱されると、除湿手段に吸着されていた水蒸気は脱離する。脱離した水蒸気は、再生送風機によって再生送風機の吹出口から、本体外へ排出される。
【００２２】
次に噴出口から乾燥空気を噴出し人体に送風する除湿モードでは、加熱手段と再生送風機を停止し、送風機を駆動する。送風機吹出口と、再生送風機の吸込口は近接して設置されているので、送風機の吹出口から送風された送風流によって、再生手段の吸込口から空気が誘引されて流出し、送風流は除湿手段に入り、空気流は除湿手段で除湿されて、熱交換器によって冷却される。送風機によって０．２m³／分の流量で除湿手段に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は吸着材で水蒸気を吸着され湿度が低下するとともに吸着熱で発熱し（６５℃、３％ＲＨ）の空気となる。高温低湿度の空気は熱交換器に導かれ車室空気で冷却され（３７℃、２０％）の低湿度空気となって通風路に導かれ表皮の噴出口から吹き出し、人体背側面を流れる。その際体表面の汗を気化させることで気化熱をうばい人体に冷涼感を与えるとともに、ムレ感をも防止する。
【００２３】
したがって、送風機の吹出口に吸込口を近接させて設置してあるので、ダンパー等で再生送風機の吸込口を塞がなくても、送風機の送風流によって、再生送風機から空気が誘引され、送風流が再生送風機から逆流して本体外へ流出することを防止できる。
【００２４】
請求項２に記載の発明は、請求項１の構成において、再生吹出送風機の吸込口に、吸込口面積を絞り、送風機の吹出口に臨ませた誘引補助手段を備えた構成としたものである。
【００２５】
上記構成において、吸着材の能力を再生させる再生モードでは送風機を停止し、加熱手段と、再生送風機を駆動させる。加熱手段で除湿手段が加熱されると、除湿手段に吸着されていた水蒸気は脱離する。脱離した水蒸気は、再生送風機によって再生送風機の吹出口から、本体外へ排出される。
【００２６】
次に、噴出口から乾燥空気を噴出し人体に送風する除湿モードでは、加熱手段と再生送風機を停止し、送風機を駆動する。誘引補助手段によって、再生送風機の吸込口は、送風機の吹出口に臨ませてあるので、再生送風機と、送風機を離れて設置しても、ダンパー等で再生送風機の吸込口を塞ぐことなく、送風機の送風流によって、再生送風機から空気が誘引され、送風流が再生送風機から逆流して本体外へ流出することを防止できる。
【００２７】
請求項３に記載の発明は、請求項１の構成において、再生吹出送風機の吸込口に、吸込口面積を絞り、送風機の送風流下流に、送風機吹出口を臨ませた後、送風路全体へ送風機の送風流を拡大する誘引補助手段を備えた構成としたものである。
【００２８】
上記構成において、吸着材の能力を再生させる再生モードでは送風機を停止し、加熱手段と、再生送風機を駆動させる。加熱手段で除湿手段が加熱されると、除湿手段に吸着されていた水蒸気は脱離する。脱離した水蒸気は、再生送風機によって再生送風機の吹出口から、本体外へ排出される。
【００２９】
次に、噴出口から乾燥空気を噴出し人体に送風する除湿モードでは、加熱手段と再生送風機を停止し、送風機を駆動する。誘引補助手段によって、再生送風機の吸込口は、送風機の吹出口に臨ませてあるので、再生送風機と、送風機を離れて設置しても、ダンパー等で再生送風機の吸込口を塞ぐことなく、送風機の送風流によって、再生送風機から空気が誘引され、送風流が再生送風機から逆流して本体外へ流出することを防止できる。さらに誘引補助手段によって送風機から吹出した送風流が送風路全体に拡大されるので、除湿手段全体に送風流が流れ込み、送風流の除湿が効率よく行われる。
【００３０】
請求項４に記載の発明は、請求項１の構成において、送風機の吹出口に、送風機からの送風流を拡大するとともに、再生送風機の吸込口を絞る拡大手段を備えた構成としたものである。
【００３１】
上記構成において、吸着材の能力を再生させる再生モードでは送風機を停止し、加熱手段と、再生送風機を駆動させる。加熱手段で除湿手段が加熱されると、除湿手段に吸着されていた水蒸気は脱離する。脱離した水蒸気は、再生送風機によって再生送風機の吹出口から、本体外へ排出される。
【００３２】
次に、噴出口から乾燥空気を噴出し人体に送風する除湿モードでは、加熱手段と再生送風機を停止し、送風機を駆動する。拡大手段によって送風機から吹出した送風流が送風路全体に拡大されるので、除湿手段全体に送風流が流れ込み、送風流の除湿が効率よく行われる。また、拡大手段によって、再生送風機の吸込口は、送風機の送風流下流に臨ませてあるので、再生送風機と、送風機を離して設置しても、ダンパー等で再生送風機の吸込口を塞ぐことなく、送風機の送風流によって、再生送風機から空気が誘引され、送風流が再生送風機から逆流して本体外へ流出することを防止できる。
【００３３】
請求項５に記載の発明は、請求項１ないし請求項４に記載の構成において、電気抵抗発熱体等の加熱手段の表面に吸着材を担持した構成であるため、再生時において加熱手段の熱が直接吸着材に伝わり吸着材の昇温速度が大きくなる。つまり再生時間を短くしても吸着した大部分の水蒸気が放出されることになる。
【００３４】
従って、短時間で吸着能力が回復するため断続的に除湿モ−ドと吸着モ−ドを繰り返しても充分な除湿能力を発揮することが出来るため吸着材を大幅に小型化でき座席本体への組込みが容易となる。また直接吸着材を加熱するため、空気を加熱することが少なく、再生電力が少なくて良い。
【００３５】
さらに長期放置された場合でも除湿手段をすぐに再生できるので、大気中の水蒸気を吸着するのを防止するための厳重なシ−ル構成や、円筒状の吸着材を回転させる構成が不要となり、空調ユニットの小型化を実現できる。
【００３６】
【実施例】
以下、本発明の実施例について図面を用いて説明する。
【００３７】
（実施例１）
図１は本発明の実施例１の空調座席装置の断面図であり、図２は除湿モードにおける座部の除湿手段等の断面図、図３は再生モードにおける座部の除湿手段等の断面図、図４は図２の送風路付近の拡大断面図、図５は図３の送風路付近の拡大断面図である。シート本体３１の座部３２、背部３３の内部に車室内空気を押込み送風するシロッコファン等の送風機３４と、前記送風機３４の吹出口４３に吸込口５０を近接させて設置したシロッコファン等の再生送風機と、前記送風機で送風された空気を除湿するコルゲート状や、粒状のゼオライトやシリカゲルや活性アルミナなどの吸着材３５からなる除湿手段３６と、送風機３４と除湿手段３６を結ぶ送風路４４と、除湿後の空気を車室内空気で冷却する仕切板４５の両側にフィン３８を設けたアルミ押出材の熱交換器３７と、熱交換器３７を強制冷却させる冷却ファン４７と、座席本体の表皮３９に設けられた空気を噴出する噴出口４０と、熱交換後の乾燥空気を噴出口に導く通風路４１と、除湿手段３６の下流に設けて加熱する電気ヒーター等の加熱手段４２と、送風機３４、再生送風機４９および冷却ファン４７の送風量を可変させることのできる制御手段４６とからなる。
【００３８】
上記構成において、図３、図５に示す、除湿手段３６の能力を再生させる再生モードでは、送風機３４を停止し、加熱手段４２と、再生送風機４９を駆動させる。加熱手段４２で除湿手段３６が加熱されると、除湿手段３６に吸着されていた水蒸気Ａは脱離する。脱離した水蒸気Ａは、再生送風機４９によって再生送風機の吹出口から、シート本体３１外へ排出される。
【００３９】
次に、車室内空気を除湿し噴出口から乾燥空気を噴出し人体に送風する除湿モードでは、図２、図４に示すように、送風機３４を駆動させて、送風機３４の吸込口４３から車室内空気を除湿手段３６へ送風させる。送風機の吹出口４３と、再生送風機吸込口５０は近接して設置されているので、送風機の吹出口４３から送風された送風流Ｂによって、再生手段の吸込口から空気Ｃが誘引されて流出し、送風流Ｂは除湿手段に入り、空気流Ａは除湿手段３６で除湿されて、熱交換器３７によって除冷却される。送風機３４によって０．２m³／分の流量で除湿手段３６に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は吸着材３５で水蒸気を吸着され湿度が低下するとともに吸着熱で発熱し（６５℃、３％ＲＨ）の空気となる。高温低湿度の空気は熱交換器３７に導かれ、熱交換器３７の下部は車室空気で冷却され（３７℃、２０％）の低湿度空気となって通風路４１に導かれ表皮の噴出口４０から吹き出し、人体背側面を流れる。その際体表面の汗を気化させることで気化熱をうばい人体に冷涼感を与えるとともに、ムレ感を防止する。
【００４０】
なお、図６に室温３５℃湿度５５％ＲＨの室内で、０．２m³／分、湿度２０％の室温以上の温度の乾燥空気を噴出した場合の噴出温度と背部の冷涼感の官能実験結果を示す。図４で示されるように３９℃以下であれば、汗の気化熱で冷涼感を得ることができる。なお、０．２m³／分温度３１℃湿度７５％の空気を噴出した場合は３８℃、２０％の乾燥空気と同じ冷涼感であった。
【００４１】
以上説明したように、送風機の吹出口４３に吸込口５０を近接させて設置してあるので、ダンパー等で再生送風機の吸込口５０を塞がなくても、送風機の送風流Ａによって、再生送風機から空気Ｂが誘引され、送風流が再生送風機４９から逆流して本体外へ流出することを防止できる。
【００４２】
なお、本発明では、両側にフィン３８を設けたアルミ押出材の熱交換器３７としたが、片側にフィンを設けたアルミ押出材のベース面を互い重ね合せてをシリコングリスなどの熱伝導材料で貼り合わせても同様の構成とすることができる。また、熱交換器の材質は、アルミ以外に銅・銀など熱伝導率の高いものを選べば熱交換性能が向上するのはいうまでもない。
【００４３】
なお、本発明では、冷却ファン４７によって車室内空気を強制的に熱交換器３７のフィン３８に吹き付けて冷却させたが、収納空間の上で熱交換器３７のサイズを大きくすることが可能であれば自然対流のみでも熱交換器３７は熱交換されて冷却されるのはいうまでもない。また、熱交換器３７にエアコンなどの空調装置の吹出風が送風されるように構成すれば、冷却ファン４７などの部品を追加させることなく、効果的に熱交換器を冷却させることができるのはいうまでもない。
なお、再生送風機４９のモーターを直流モーターとし、回転数を制御する制御手段４６を設けた構成においては、再生モード時は再生送風機４９の送風量を、０．０２m³／分微弱風となるよう制御する。加熱手段４２を通電すると、空気の温度が１２０℃〜１４０℃となって除湿手段３６の吸着材３５に送られ、吸着材３５を加熱するとともに、吸着材３５から脱離した水蒸気を吹き飛ばし、除湿手段３６の吸着材の再生を短時間で行うことができる。
【００４４】
このようにして、送風機３４と再生送風機４９を交互に動作させることにより、除湿運転と吸着材の再生運転を交互に繰り返す間欠運転させることで、人体に冷涼感を与える。吸着材の再生運転中では、座席表面に送風させることができないが、再生時間が短いため、冷涼感に違和感はない。また、間欠運転は、ゆらぎ制御のような効果をもたらすとともに、除湿を定常運転させるよりも効果的な冷涼感を得ることができる。これは、除湿運転していないときに、人体が発汗した後に、除湿運転をすると、気化熱を奪われ、効果的に冷涼感を得ることになるからである。
【００４５】
また、図７に示すように、吹出口５２を通風路４１に向くようにし誘引板５３を設けて噴出口４０に送風を可能とする送風ファン５１を設けた構成では、除湿手段３６の除湿性能を回復させる再生モード時において、加熱手段４２、再生送風機４９、送風ファン５１を駆動することで再生運転中でも、座席表面に車室内空気を送風させることができるので、除湿運転と送風運転を交互に繰り返すことができ、座席表面には、全体として連続して風を送ることができる。また、車室内空気を除湿し噴出口から乾燥空気を噴出し人体に送風する除湿モードでは、送風機３４を駆動させて、除湿空気を通風路４１へ送風する。この場合誘引板５３付近の除湿空気流によって、吹出口５２から車室内空気が通風路へ誘引されるので、ダンパ等の特別な機構を設けなくても、送風ファンから除湿空気が車室内に漏れることは無い。
【００４６】
なお、図１の座席装置のように、背部と座部にそれぞれ１つずつ装置を組み込んだ場合で説明したが、座部のみ、あるいは、他の車内の空間を利用して、１つの装置で背部と座部に送風させる方法でもよい。この場合、背部と座部の両方に除湿送風させるだけの能力から多少サイズが大きくなるが、１つの装置で済むので部品点数が減り、安価とすることができる。
【００４７】
（実施例２）
図８は、本発明の実施例２の通風路付近の拡大断面図、図９は除湿手段の斜視図、図１０は除湿手段の断面図、図１１は加熱手段の展開正面図であり、実施例１の構成において、除湿手段３６として、電気抵抗発熱体等の加熱手段４２の表面に吸着材３５を担持した構成としたものである。
【００４８】
図８、図９に示すように、除湿手段の内部に加熱手段を備えているため、再生時において加熱手段４２の熱が直接吸着材３５に伝わり吸着材の昇温速度が大きくなる。つまり再生時間を短くしても吸着した大部分の水蒸気が放出されることになる。従って短時間で吸着能力が回復するため断続的に除湿モ−ドと吸着モ−ドを繰り返しても充分な除湿能力を発揮することが出来るため吸着材を大幅に小型化でき座席本体への組込みが容易となる。また直接吸着材６１を加熱するため、空気を加熱することが少なく、再生電力が少なくて良い。
【００４９】
さらに長期放置された場合でも除湿手段をすぐに再生できるので、大気中の水蒸気を吸着するのを防止するための厳重なシ−ル構成や、円筒状の吸着材を回転させる構成が不要となり、空調ユニットの小型化を実現できる。
【００５０】
なお、図１０、図１１は、ステンレス等のエキスパンドメタル表面に水酸化アルミニウムや硝酸セリウム等を焼結酸化させたアンダーコート５４を施し、ゼオライト、チタシリケート、シリカゲル、活性アルミナ等の吸着材３５を担持させ、加熱手段４２をエキスパンドメタル５５で構成したものである。除湿モードではエキスパンドメタルの網目は開口しているので吸着材への接触面積が多くなり、また多孔体のため、送風の圧力損失を低くすることができる。再生モードでは、エキスパンドメタル５５全面に接触するように溶接した端子５６に通電させて発熱させる。エキスパンドメタルは薄板に切れ込みの入った構成のため、薄板に比べ同じ電気抵抗でも低熱容量であり、再生時間を短くすることができる。
【００５１】
（実施例３）
図１２は本発明の実施例３における、除湿モードの通風路付近の拡大断面図、図１３は再生モードにおける通風路付近の拡大断面図である。本実施例では、実施例１の構成において、再生送風機４９の吸込口５０に、吸込口面積を絞り、送風機吹出口を臨ませた誘引補助手段５７を備えた構成としたものである。なお、実施例１、実施例２と同一符号のものは同一構造を有し、説明は省略する。
【００５２】
上記構成において、図１３に示す吸着材の能力を再生させる再生モードでは送風機３４を停止し、加熱手段４２と、再生送風機４９を駆動させる。加熱手段４２で除湿手段３６の吸着材３５が加熱されると、吸着材に吸着されていた水蒸気Ａは脱離する。脱離した水蒸気Ａは、再生送風機４９によって再生送風機４９の吹出口から、本体外へ排出される。
【００５３】
次に、図１２に示す噴出口４０から乾燥空気を噴出し人体に送風する除湿モードでは、加熱手段４２と再生送風機４９を停止し、送風機３４を駆動する。誘引補助手段５７によって、再生送風機の吸込口５０は、送風機３４の吹出口４３に臨ませてあるので、再生送風機と、送風機を離れて設置しても、ダンパー等で再生送風機の吸込口を塞ぐことなく、送風機の送風流によって、再生送風機から空気Ｃが誘引され、送風流が除湿手段に送られず再生送風機から逆流して本体外へ流出することを防止できる。
【００５４】
なお、誘引補助手段５７の先端部５８は、送風機３４の吹出口４３の延長線上にまで伸ばすことが理想であるが、送風流のせん断力が及ぶ範囲まで離しても同様の効果が得られる。
【００５５】
なお、図１４に示すように、再生吹出送風機４９の吸込口５０に、吸込口面積を絞り、送風機３４の送風流下流に、送風機吹出口を臨ませた後、送風路４４全体へ送風機の送風流Ｂを拡大する誘引補助手段５７を設けた構成においては、除湿モードでは、加熱手段４２と再生送風機４９を停止し、送風機３４を駆動する。誘引補助手段５７によって、再生送風機４９の吸込口５０は、送風機の吹出口４３に臨ませてあるので、再生送風機４９と、送風機３４を離れて設置しても、ダンパー等で再生送風機の吸込口５０を塞ぐことなく、送風機３４の送風流Ｂによって、再生送風機４９から空気が誘引され、送風流Ｂが再生送風機４９から逆流して本体外へ流出することを防止できる。さらに誘引補助手段５７によって送風機から吹出した送風流Ｂが送風路４４全体に拡大されるので、除湿手段３６全体に送風流Ｂが流れ込み、送風流の除湿が効率よく行われる。
【００５６】
以上述べたように、本実施例によれば除湿モード、再生モードを行う際でもダンパーなどの風路切替駆動手段を設けずに、送風機のみで構成することができるので、簡単でコストの低減ができるとともに、車の走行中の振動、耐久性についてはダンパーを使用する構成に比べて信頼性の優れたものを実現できる。
【００５７】
（実施例４）
図１５は本発明の実施例４における、除湿モードの通風路付近の拡大断面図、図１６は再生モードにおける通風路付近の拡大断面図である。本実施例では、実施例１の構成において、送風機の吹出口に、送風機３４からの送風流を拡大するとともに、再生送風機４９の吸込口５０を絞る拡大手段５９を備えた構成としたものである。なお、実施例１、実施例２と同一符号のものは同一構造を有し、説明は省略する。
【００５８】
上記構成において、除湿手段３６の能力を再生させる再生モードでは、図１６に示すように、送風機３４を停止し、加熱手段４２と、再生送風機４９を駆動させる。加熱手段で除湿手段が加熱されると、除湿手段に吸着されていた水蒸気は脱離する。脱離した水蒸気Ａは、再生送風機４９によって再生送風機４９の吹出口から、シート本体３１外へ排出される。
【００５９】
次に、噴出口４０から乾燥空気を噴出し人体に送風する除湿モードでは、図１５に示すように加熱手段４２と再生送風機４９を停止し、送風機３４を駆動する。拡大手段５９によって送風機３４から吹出した送風流Ｂが送風路４４全体に拡大されるので、除湿手段３６全体に送風流が流れ込み、送風流の除湿が効率よく行われる。また、拡大手段によって、再生送風機４９の吸込口は、送風機の送風流Ｂ下流に臨ませてあるので、再生送風機４９と、送風機３４を離して設置しても、ダンパー等で再生送風機４９の吸込口５０を塞ぐことなく、送風機３４の送風流Ｂによって、再生送風機４９から空気Ｃが誘引され、送風流Ｂが再生送風機４９から逆流してシート本体３１外へ流出することを防止できる。
【００６０】
【発明の効果】
以上のように、本発明の空調座席装置によれば、再生送風機の吸込口は、送風機の吹出口に臨ませてあるので、風路を切替えたり、開閉を行うためのダンパーが必要ない。このようにしてダンパーがある構成よりも簡易で、安価で、ダンパー駆動電力も必要ないので電力消費が少なくできる。また、車の振動などによりダンパーが変形して動作しなくなるといった信頼性を配慮する必要がなくなる。
【００６１】
このようにして、噴出口から吹出した乾燥空気が体表面の汗を気化させることで気化熱をうばい人体に冷涼感を与えるとともに、ムレ感をも防止するので、特に夏季の車内の座席を急速に快適な着座感を有するものとすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a device having a function of holding a human body and air-conditioning like a seat, for example, as a car seat, an office chair, a sitting chair, a chaise longue, a bed, a futon etc. equipped with a dehumidifying device. Used.
[0002]
[Prior art]
The structure shown below is disclosed by the 1st prior art example as this kind of conventional air-conditioning seat apparatus (for example, refer to patent documents 1). As shown in FIG. 17 showing the first conventional example, an air bag 3 for forcibly sucking outside air through a portion of the skin cloth 2 corresponding to a portion where the back of the human body contacts the seat body 1 is incorporated in the seat body 1. In addition, a dehumidifying and drying device 6 comprising a cooling dehumidifier 4 and a heating dryer 5 for dehumidifying and drying the outside air taken in by the air bag 3 and exhausting it to the back of the human body through the air bag 3 is built in the headrest. The drying device 6 and the air bag 3 are configured to communicate with each other through an intake air passage 7 and an exhaust air passage 8.
[0003]
In the above configuration, the outside air (32 ° C., humidity 80%) on the back of the human body is sucked into the air bag 3 through the skin cloth 2 and enters the cooling dehumidifier 4 through the intake air passage 7 to be cooled and dehumidified (condensed) (15 ° C.). , 100%), and is sent to the heat dryer 5 to be heated and dried (30 ° C., 50%), enters the air bag 3 through the exhaust air passage 8, and blows out from the skin cloth 2 toward the back of the human body. It prevents stuffiness while preventing the body temperature from being taken away by the cooling air.
[0004]
However, in the above-described conventional configuration, dehumidification is performed by the cooling dehumidifier 4, so a drain pipe (not shown) for flowing condensed water is necessary, and special processing is required for the automobile main body and the like. Also, it cannot be easily used as a movable office chair.
[0005]
Moreover, the air-conditioning seat apparatus of the 2nd prior art example using a hygroscopic material is disclosed as follows (for example, patent document 2). That is, as shown in FIGS. 18, 19, and 20 of the second conventional example, the backrest portion 9 has an air passage 10 therein, and the water vapor partial pressure is between the backrest portion 9 and the air passage 10. A moisture-permeable layer 11 having both non-breathability and moisture permeability according to the gradient is disposed, and moisture vapor that permeates from the backrest portion 9 flows into the air passage 10. Then, by passing the air dried through the air drying device 12 provided with a hygroscopic material to the air passage 10, the moisture permeable layer 11 permeates the water vapor outside the backrest 9, and the water vapor evaporates in the dry air. .
[0006]
As shown in FIG. 19, the air drying device 12 is a reaction vessel 15 and 16 filled with adsorbing materials 17 and 18 such as zeolite or silica gel having an air inlet, and each is an integrated electric vessel. The flow path is switched to a passage outlet 20 having heaters 21 and 22 and connected to the inlet of the air passage 10 by an electrically driven air flap 14 and an in-car outlet 19 opened in the passenger compartment. .
[0007]
In the above configuration, in order to continuously operate the air drying apparatus 12, the two reaction vessels 15 and 16 are alternately switched between the moisture absorption process and the regeneration process. When the adsorbing material 17 in one reaction vessel 15 is regenerated by the electric heater 21 (regeneration process), the other reaction vessel 16 dries the air flowing through the inside by the hygroscopic action of the adsorbing material 18 and heats of adsorption. To heat the air (moisture absorption process). When the adsorbing material 18 in the reaction vessel 16 is saturated, the air flap 14 is switched as indicated by a broken line, the electric heater 22 is energized to regenerate the adsorbing material 18 in the reaction vessel 16, and the reaction vessel 15 uses the air flowing through the adsorbing material to adsorb the air. Dry by the hygroscopic action of 17. In addition, as shown in FIG. 20, the fan 23 may be disposed in the vicinity of the vehicle interior outlet 19.
[0008]
However, in the above conventional configuration, sweat generated in the human body is not absorbed except in contact with the chair, and moisture is absorbed through the clothing and the moisture permeable layer 11, so that the amount of absorbed sweat is small. It was. Further, since the temperature of the air that has exited the air drying device 12 is high due to the heat of adsorption, even if it is blown out from the backrest 9 as it is, a cool feeling cannot be obtained.
[0009]
Moreover, the following content is disclosed as a 3rd prior art example which performs adsorption | suction reproduction | regeneration continuously using adsorption material (for example, refer patent document 3). As shown in FIG. 21, a cylindrical adsorbent 24 formed in a corrugated or honeycomb shape is known, and is used in a humidity control device for adjusting the humidity of air. The adsorbent 24 is slowly rotated by the driving motor 26 via the timing belt 25, and the air sent by the regeneration fan 27 is sent to the adsorbent 24 heated to a high temperature by the regeneration heater 28. The water adsorbed on the water is desorbed and discharged as moist air 29a. Then, the adsorbent 24 regenerated by releasing moisture is rotated and blows the high-humidity air supplied by the blower fan 30 to the position where the adsorbent 24 is regenerated, and is introduced into the adsorbent 24 to adsorb the water vapor and dry. It becomes the structure discharged | emitted as the air 29b, and can dehumidify high-humidity air continuously.
[0010]
However, in the above-described conventional configuration, the heat of the adsorbent 24 at the site where moisture is desorbed and regenerated is transmitted to the site where the moisture is dehumidified, so that the temperature of the dry air 29b increases, and the dry air 29b provides a cool feeling. It is unsuitable for such a device. Moreover, since the adsorbent 24 is indirectly heated by the air heated to a high temperature by the heater 28, the heating efficiency of the adsorbent 24 is low and the power consumption is large. Moreover, since the heat that has not been transferred to the adsorbent 24 is exhausted in large amounts as high-temperature humid air, the temperature of the room rises, making it unsuitable for an apparatus that provides a cool feeling. Further, the air path is complicated, and a configuration for rotating the adsorbent 24 is necessary. Since the adsorbent 24 is also large, it is difficult to reduce the size of the apparatus.

[Problems to be solved by the invention]
However, in the conventional apparatus, the two reaction vessels are alternately switched between the moisture absorption process and the regeneration process, thereby enabling continuous operation. In this case, two reaction vessels are required, which increases the size of the apparatus, the number of parts, and the cost.
[0013]
In the case of a rotor type in which a cylindrical adsorbent molded in a corrugated or honeycomb shape is rotated to perform dehumidification operation and regeneration of the adsorbent, the heat of the adsorbent at the portion where moisture is desorbed is dehumidified. Therefore, the temperature of the dry air becomes high, and the dry air is unsuitable for a device that provides a cool feeling with the dry air. In addition, since the adsorbent is indirectly heated by air heated to a high temperature by a heater, the adsorbent heating efficiency is low, the power consumption is large, and the regeneration time is long.
[0014]
Moreover, since the heat that has not been transferred to the adsorbent is exhausted in large amounts as high-temperature humid air, the temperature of the room rises, making it unsuitable for a device that provides a cool feeling. In addition, since the adsorbent is not sufficiently regenerated and dried by the amount of heat not transferred to the adsorbent, the apparatus has a low adsorption efficiency. Furthermore, since the air path is complicated, a configuration for rotating the adsorbent is necessary, and the adsorbent becomes large, so it is difficult to reduce the size of the apparatus. Furthermore, in order to perform the adsorption operation and the regeneration operation continuously, generally, two fans, a blower for blowing dry air and a blower for regenerating the adsorbent, are necessary, so that the apparatus becomes large and the number of parts becomes large. It had the problem of increasing the cost.
[0015]
The present invention solves the above-described conventional problems, and does not require the treatment of adsorbent condensed water with a simple configuration without a damper (flap) or an adsorbent drive mechanism and capable of continuous operation of regeneration and adsorption. The purpose of the present invention is to realize an air-conditioning seat device in which the temperature of the human body can be felt low even when the room temperature is high. Furthermore, it aims at realization of the small air-conditioning seat apparatus with high heating efficiency and quick regeneration time of a dehumidification material.
[0016]
[Means for Solving the Problems]
In order to solve the above-described conventional problems, an air-conditioning seat device according to the present invention reproduces a blower such as a sirocco fan that blows air in the passenger compartment, and a sirocco fan that is installed with a suction port close to the blower outlet of the blower. A heat exchanger that dehumidifies the air blown by the blower with an adsorbent such as silica gel or activated alumina, and air that has been dehumidified is cooled with room air. And a heating means for heating the dehumidifying means, a jet outlet for jetting air provided on the skin of the seat body, and a ventilation path for guiding the dry air after heat exchange in the heat exchanger to the jet outlet It is.
[0017]
In the above configuration, in the regeneration mode for regenerating the capacity of the adsorbent, the blower is stopped and the heating means and the regeneration fan are driven. When the dehumidifying means is heated by the heating means, the water vapor adsorbed on the dehumidifying means is desorbed. The desorbed water vapor is discharged out of the main body from the outlet of the regenerative blower by the regenerative blower.
[0018]
Next, in the dehumidifying mode in which dry air is blown out from the outlet and blown to the human body, the heating means and the regenerative blower are stopped and the blower is driven. Since the blower outlet and the regenerative blower suction port are installed close to each other, air is attracted and flows out from the suction port of the regenerating means by the air flow blown from the blower blower outlet, and the air flow flows to the dehumidifying means. Once entered, the air stream is dehumidified by dehumidifying means and cooled by a heat exchanger. 0.2m depending on the blower ^Three The air in the passenger compartment (35 ° C, 55% RH) sent to the dehumidifying means at a flow rate of / min is adsorbed by water vapor by the adsorbent and the humidity decreases and heat is generated by the adsorption heat (65 ° C, 3% RH). It becomes air. The high-temperature, low-humidity air is guided to the heat exchanger, cooled by the passenger compartment air (37 ° C., 20%) as low-humidity air, led to the ventilation path, blown out from the spout of the epidermis, and flows on the back side of the human body. At that time, the sweat on the surface of the body is vaporized to give a cool feeling to the human body and to prevent the feeling of stuffiness.
[0019]
In addition, since the suction port is installed close to the blower outlet, air is attracted from the regenerative blower by the blower flow even if the damper's suction port is not blocked by a damper or the like. Can be prevented from flowing backward from the regenerative blower and out of the main body.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
The invention described in claim 1 includes a blower such as a sirocco fan that blows air in the passenger compartment, a regenerative blower such as a sirocco fan installed with a suction port close to a blower outlet of the blower, the blower, and the dehumidifying means. A dehumidifying means for dehumidifying the air blown by the blower with an adsorbent such as silica gel or activated alumina, a heat exchanger for cooling the dehumidified air with room air, and heating for heating the dehumidifying means Means, a jet outlet for jetting air provided in the skin of the seat body, and a ventilation path for guiding the dry air after heat exchange by the heat exchanger to the jet outlet.
[0021]
In the above configuration, in the regeneration mode for regenerating the capacity of the adsorbent, the blower is stopped and the heating means and the regeneration fan are driven. When the dehumidifying means is heated by the heating means, the water vapor adsorbed on the dehumidifying means is desorbed. The desorbed water vapor is discharged out of the main body from the outlet of the regenerative blower by the regenerative blower.
[0022]
Next, in the dehumidifying mode in which dry air is blown out from the outlet and blown to the human body, the heating means and the regenerative blower are stopped and the blower is driven. Since the blower outlet and the suction port of the regenerative blower are installed close to each other, air is drawn out from the suction port of the regeneration means by the air flow blown from the blower outlet, and the air flow is dehumidified. Entering the means, the air stream is dehumidified by the dehumidifying means and cooled by the heat exchanger. 0.2m by blower ^Three The air in the passenger compartment (35 ° C, 55% RH) sent to the dehumidifying means at a flow rate of / min is adsorbed by water vapor by the adsorbent and the humidity decreases and heat is generated by the adsorption heat (65 ° C, 3% RH). It becomes air. The high-temperature, low-humidity air is guided to the heat exchanger, cooled by the passenger compartment air (37 ° C., 20%) as low-humidity air, led to the ventilation path, blown out from the spout of the epidermis, and flows on the back side of the human body. At that time, the sweat on the surface of the body is vaporized to give a cool feeling to the human body and to prevent the feeling of stuffiness.
[0023]
Therefore, since the suction port is installed close to the blower outlet, air is attracted from the regenerative blower by the blower flow even if the suction port of the regenerative blower is not blocked by a damper or the like. Can be prevented from flowing backward from the regenerative blower and out of the main body.
[0024]
Invention of Claim 2 is set as the structure provided with the attraction | suction assistance means which restrict | squeezed the inlet area to the suction inlet of the reproduction | regeneration blower fan, and faced the blower outlet in the structure of Claim 1. .
[0025]
In the above configuration, in the regeneration mode for regenerating the capacity of the adsorbent, the blower is stopped and the heating means and the regeneration fan are driven. When the dehumidifying means is heated by the heating means, the water vapor adsorbed on the dehumidifying means is desorbed. The desorbed water vapor is discharged out of the main body from the outlet of the regenerative blower by the regenerative blower.
[0026]
Next, in the dehumidifying mode in which dry air is ejected from the ejection port and blown to the human body, the heating means and the regenerative blower are stopped and the blower is driven. The suction inlet of the regenerative blower faces the blower outlet of the blower by the attraction assisting means. Even if the regenerative blower and the blower are installed away from each other, the blower is not blocked by the damper or the like. By this air flow, air is attracted from the regenerative blower, and it can be prevented that the air flow flows backward from the regenerative blower and flows out of the main body.
[0027]
The invention according to claim 3 is the configuration of claim 1, after narrowing the suction port area to the suction port of the regenerative blower blower, and facing the blower blower outlet downstream of the blower flow of the blower, to the entire blower passage It is set as the structure provided with the attraction assistance means which expands the ventilation flow of an air blower.
[0028]
In the above configuration, in the regeneration mode for regenerating the capacity of the adsorbent, the blower is stopped and the heating means and the regeneration fan are driven. When the dehumidifying means is heated by the heating means, the water vapor adsorbed on the dehumidifying means is desorbed. The desorbed water vapor is discharged out of the main body from the outlet of the regenerative blower by the regenerative blower.
[0029]
Next, in the dehumidifying mode in which dry air is ejected from the ejection port and blown to the human body, the heating means and the regenerative blower are stopped and the blower is driven. The suction inlet of the regenerative blower faces the blower outlet of the blower by the attraction assisting means. Even if the regenerative blower and the blower are installed away from each other, the blower is not blocked by the damper or the like. By this air flow, air is attracted from the regenerative blower, and it can be prevented that the air flow flows backward from the regenerative blower and flows out of the main body. Furthermore, since the blowing flow blown out from the blower by the attraction assisting means is expanded to the entire blowing path, the blowing flow flows into the entire dehumidifying means, and the blowing flow is efficiently dehumidified.
[0030]
Invention of Claim 4 is set as the structure provided with the expansion means which restrict | squeezes the suction inlet of a reproduction | regeneration blower while expanding the ventilation flow from a blower in the blower outlet of the blower in the structure of Claim 1. .
[0031]
In the above configuration, in the regeneration mode for regenerating the capacity of the adsorbent, the blower is stopped and the heating means and the regeneration fan are driven. When the dehumidifying means is heated by the heating means, the water vapor adsorbed on the dehumidifying means is desorbed. The desorbed water vapor is discharged out of the main body from the outlet of the regenerative blower by the regenerative blower.
[0032]
Next, in the dehumidifying mode in which dry air is ejected from the ejection port and blown to the human body, the heating means and the regenerative blower are stopped and the blower is driven. Since the blowing flow blown out from the blower by the expanding means is expanded to the entire blowing path, the blowing flow flows into the entire dehumidifying means, and the blowing flow is efficiently dehumidified. In addition, because the suction port of the regenerative blower faces the downstream side of the air flow of the blower by the expanding means, even if the regenerative blower and the blower are installed separately, the suction port of the regenerative blower is not blocked by a damper or the like. The air from the regenerative blower is attracted by the air flow of the blower, and the air flow can be prevented from flowing back from the regenerative blower and flowing out of the main body.
[0033]
The invention according to claim 5 is the structure according to claims 1 to 4 in which the adsorbent is supported on the surface of the heating means such as an electric resistance heating element. Is directly transferred to the adsorbent, and the temperature rise rate of the adsorbent increases. That is, even if the regeneration time is shortened, most of the adsorbed water vapor is released.
[0034]
Therefore, since the adsorption capacity can be recovered in a short time, even if the dehumidification mode and the adsorption mode are repeated intermittently, sufficient dehumidification capacity can be exhibited. Easy to install. Further, since the adsorbent is directly heated, the air is hardly heated and the regenerative power is small.
[0035]
Furthermore, even if left for a long period of time, the dehumidifying means can be regenerated immediately, eliminating the need for a strict seal configuration to prevent adsorption of water vapor in the atmosphere and a configuration that rotates a cylindrical adsorbent, The air conditioning unit can be downsized.
[0036]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0037]
(Example 1)
1 is a cross-sectional view of an air-conditioning seat device according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view of a dehumidifying means for a seat in a dehumidifying mode, and FIG. 3 is a cross-sectional view of a dehumidifying means for a seat in a regeneration mode. 4 is an enlarged sectional view in the vicinity of the air passage in FIG. 2, and FIG. 5 is an enlarged sectional view in the vicinity of the air passage in FIG. Regeneration of a blower 34 such as a sirocco fan that pushes air inside the seat 32 and the back 33 of the seat body 31 and blows the air inside the vehicle interior, and a sirocco fan installed close to the air outlet 43 of the blower 34. A blower, a corrugated shape that dehumidifies the air blown by the blower, a dehumidifying means 36 made of an adsorbent 35 such as granular zeolite, silica gel, activated alumina, and the like, and a blower path 44 connecting the blower 34 and the dehumidifying means 36, A heat exchanger 37 of an aluminum extrusion material provided with fins 38 on both sides of a partition plate 45 that cools the air after dehumidification with air in the passenger compartment, a cooling fan 47 that forcibly cools the heat exchanger 37, and a skin 39 of the seat body A jet outlet 40 for jetting air, a ventilation passage 41 for guiding the dried air after heat exchange to the jet outlet, an electric heater for heating provided by the downstream of the dehumidifying means 36, etc. And heating means 42, blower 34, and a control unit 46 capable of varying the air volume of the playback blower 49 and the cooling fan 47.
[0038]
In the above configuration, in the regeneration mode for regenerating the ability of the dehumidifying means 36 shown in FIGS. 3 and 5, the blower 34 is stopped, and the heating means 42 and the regeneration blower 49 are driven. When the dehumidifying means 36 is heated by the heating means 42, the water vapor A adsorbed on the dehumidifying means 36 is desorbed. The desorbed water vapor A is discharged out of the sheet main body 31 from the outlet of the regeneration fan by the regeneration fan 49.
[0039]
Next, in the dehumidifying mode in which the air in the passenger compartment is dehumidified and the dry air is blown out from the jet outlet and blown to the human body, as shown in FIGS. 2 and 4, the blower 34 is driven and the vehicle is moved from the suction port 43 of the blower 34. The room air is blown to the dehumidifying means 36. Since the blower outlet 43 and the regenerative blower suction port 50 are installed close to each other, the air C is drawn from the suction port of the regenerating means and flows out by the air flow B blown from the blower outlet 43 of the blower. The air flow B enters the dehumidifying means, and the air flow A is dehumidified by the dehumidifying means 36 and decooled by the heat exchanger 37. 0.2m by blower 34 ^Three The air in the passenger compartment (35 ° C., 55% RH) sent to the dehumidifying means 36 at a flow rate of / min is adsorbed by the adsorbent 35 to reduce the humidity and generate heat due to the heat of adsorption (65 ° C., 3% RH). ) Air. The high-temperature and low-humidity air is guided to the heat exchanger 37, and the lower part of the heat exchanger 37 is cooled by the passenger compartment air (37 ° C., 20%) as low-humidity air and led to the ventilation path 41 to spray the skin. It blows out from the outlet 40 and flows on the back side of the human body. At that time, the sweat on the surface of the body is vaporized to give a cool feeling to the human body and to prevent the feeling of stuffiness.
[0040]
In FIG. 6, the room temperature is 35 ° C. and the humidity is 55% RH. ^Three 1 shows the sensory test results of the jetting temperature and the coolness of the back when jetting dry air at a temperature of room temperature or higher with a humidity of 20% / min. If it is 39 degrees C or less as FIG. 4 shows, a cool feeling can be acquired with the heat of vaporization of sweat. 0.2m ^Three When air at a temperature of 31 ° C./humidity of 75% was ejected, the cooling feeling was the same as that of dry air at 38 ° C. and 20%.
[0041]
As described above, since the suction port 50 is installed close to the blower outlet 43 of the blower, even if the suction port 50 of the regenerative blower is not blocked by a damper or the like, the regenerative blower is used by the blower air flow A. Therefore, it is possible to prevent the air B from being attracted and the air flow from the regenerative blower 49 to flow out of the main body.
[0042]
In the present invention, the aluminum extrudate heat exchanger 37 is provided with fins 38 on both sides, but the base surfaces of the aluminum extrudates provided with fins on one side are overlapped with each other to form a heat conductive material such as silicon grease. Even if they are attached together, the same structure can be obtained. Needless to say, if the heat exchanger is made of a material having high thermal conductivity such as copper or silver in addition to aluminum, the heat exchange performance is improved.
[0043]
In the present invention, the cooling fan 47 forcibly blows the passenger compartment air onto the fins 38 of the heat exchanger 37 to cool it, but it is possible to increase the size of the heat exchanger 37 in the storage space. Needless to say, if only natural convection is present, the heat exchanger 37 is cooled by heat exchange. Further, if the heat exchanger 37 is configured so that the blown air from an air conditioner such as an air conditioner is blown, the heat exchanger can be effectively cooled without adding components such as the cooling fan 47. Needless to say.
In the configuration in which the motor of the regenerative blower 49 is a direct current motor and the control means 46 for controlling the rotational speed is provided, the air flow rate of the regenerative blower 49 is set to 0.02 m in the regeneration mode. ^Three Control the wind to be weak per minute. When the heating means 42 is energized, the temperature of the air becomes 120 ° C. to 140 ° C. and is sent to the adsorbent 35 of the dehumidifying means 36 to heat the adsorbent 35 and blow off the water vapor desorbed from the adsorbent 35 to dehumidify. The adsorbent of the means 36 can be regenerated in a short time.
[0044]
In this manner, by alternately operating the blower 34 and the regenerative blower 49, a cool feeling is given to the human body by intermittently repeating the dehumidifying operation and the adsorbent regenerating operation. During the regeneration operation of the adsorbent, it is not possible to blow air on the seat surface, but since the regeneration time is short, there is no sense of incongruity in the cool feeling. In addition, the intermittent operation can bring about an effect such as fluctuation control, and can obtain a cooler feeling that is more effective than that in which dehumidification is performed in a steady manner. This is because when the dehumidifying operation is performed after the human body sweats when the dehumidifying operation is not performed, the heat of vaporization is deprived and a cool feeling is effectively obtained.
[0045]
Further, as shown in FIG. 7, the dehumidifying performance of the dehumidifying means 36 is provided in the configuration in which the blowing plate 52 is provided so as to face the air passage 41 so that the blowing plate 51 is provided and the blower fan 51 can be blown to the outlet 40. In the regeneration mode for restoring the air, the vehicle interior air can be blown to the seat surface even during the regeneration operation by driving the heating means 42, the regeneration blower 49, and the blower fan 51. Therefore, the dehumidifying operation and the air blowing operation are alternately performed. The wind can be sent continuously to the seat surface as a whole. Further, in the dehumidifying mode in which the vehicle interior air is dehumidified and dry air is blown out from the jet outlet and blown to the human body, the blower 34 is driven to blow the dehumidified air to the air passage 41. In this case, the air in the vehicle interior is attracted from the outlet 52 to the ventilation path by the dehumidified air flow in the vicinity of the attracting plate 53, so that the dehumidified air leaks from the blower fan to the vehicle interior without providing a special mechanism such as a damper. There is nothing.
[0046]
In addition, although it demonstrated by the case where one apparatus was each integrated in the back part and the seat part like the seat apparatus of FIG. 1, only one seat part or the space in another vehicle was used, and one apparatus was used. A method of blowing air to the back portion and the seat portion may be used. In this case, the size is somewhat increased due to the ability to dehumidify and blow air to both the back portion and the seat portion, but since only one device is required, the number of parts can be reduced and the cost can be reduced.
[0047]
(Example 2)
8 is an enlarged cross-sectional view of the vicinity of the ventilation path according to the second embodiment of the present invention, FIG. 9 is a perspective view of the dehumidifying means, FIG. 10 is a cross-sectional view of the dehumidifying means, and FIG. 11 is an exploded front view of the heating means. In the configuration of Example 1, as the dehumidifying means 36, the adsorbent 35 is supported on the surface of the heating means 42 such as an electric resistance heating element.
[0048]
As shown in FIGS. 8 and 9, since the heating means is provided inside the dehumidifying means, the heat of the heating means 42 is directly transmitted to the adsorbent 35 during regeneration, and the temperature raising rate of the adsorbent increases. That is, even if the regeneration time is shortened, most of the adsorbed water vapor is released. Therefore, since the adsorption capacity can be recovered in a short time, even if the dehumidification mode and adsorption mode are repeated intermittently, sufficient dehumidification capacity can be exhibited, so the adsorbent can be greatly reduced in size and incorporated into the seat body. Becomes easy. In addition, since the adsorbent 61 is directly heated, the air is hardly heated and the regenerative power is small.
[0049]
Furthermore, even if left for a long period of time, the dehumidifying means can be regenerated immediately, eliminating the need for a strict seal configuration to prevent adsorption of water vapor in the atmosphere and a configuration that rotates a cylindrical adsorbent, The air conditioning unit can be downsized.
[0050]
In FIGS. 10 and 11, an undercoat 54 obtained by sintering and oxidizing aluminum hydroxide, cerium nitrate or the like is applied to the surface of an expanded metal such as stainless steel, and an adsorbent 35 such as zeolite, titasilicate, silica gel or activated alumina is provided. The heating means 42 is composed of an expanded metal 55. In the dehumidifying mode, since the expanded metal mesh is open, the contact area with the adsorbent is increased, and the pressure loss of the blast can be reduced because of the porous body. In the reproduction mode, the terminal 56 welded so as to be in contact with the entire surface of the expanded metal 55 is energized to generate heat. Expanded metal has a structure in which a thin plate is cut, so that it has a low heat capacity even with the same electric resistance as a thin plate, and can shorten the reproduction time.
[0051]
(Example 3)
FIG. 12 is an enlarged cross-sectional view in the vicinity of the ventilation path in the dehumidification mode in Example 3 of the present invention, and FIG. 13 is an enlarged cross-sectional view in the vicinity of the ventilation path in the regeneration mode. In the present embodiment, in the configuration of the first embodiment, the suction assisting means 57 is provided in which the suction port area of the regenerative blower 49 is narrowed to face the blower outlet. In addition, the thing of the same code | symbol as Example 1 and Example 2 has the same structure, and abbreviate | omits description.
[0052]
In the above configuration, in the regeneration mode for regenerating the capacity of the adsorbent shown in FIG. 13, the blower 34 is stopped, and the heating means 42 and the regeneration fan 49 are driven. When the adsorbent 35 of the dehumidifying means 36 is heated by the heating means 42, the water vapor A adsorbed on the adsorbent is desorbed. The desorbed water vapor A is discharged out of the main body from the outlet of the regeneration fan 49 by the regeneration fan 49.
[0053]
Next, in the dehumidifying mode in which dry air is ejected from the ejection port 40 shown in FIG. 12 and blown to the human body, the heating means 42 and the regenerative blower 49 are stopped and the blower 34 is driven. Since the suction inlet 50 of the regenerative blower faces the air outlet 43 of the blower 34 by the attraction assisting means 57, even if the regenerative blower and the blower are installed apart from each other, the suction blower inlet is closed by a damper or the like. Therefore, it is possible to prevent the air C from being attracted from the regenerative blower by the air flow of the blower, and the air flow is not sent to the dehumidifying means but flows backward from the regenerative blower and flows out of the main body.
[0054]
It should be noted that the tip 58 of the attraction assisting means 57 is ideally extended to the extension line of the blower outlet 43 of the blower 34, but the same effect can be obtained even if it is separated to a range where the shear force of the blown air flow is reached.
[0055]
As shown in FIG. 14, after reducing the suction port area to the suction port 50 of the regenerative blower blower 49 and facing the blower blower outlet downstream of the blower 34, the blower is sent to the entire blower path 44. In the configuration provided with the attraction assisting means 57 for expanding the airflow B, the heating means 42 and the regenerative blower 49 are stopped and the blower 34 is driven in the dehumidifying mode. Since the suction inlet 50 of the regenerative blower 49 faces the air outlet 43 of the blower by the attraction assisting means 57, even if the regenerative blower 49 and the blower 34 are installed apart from each other, the suction opening of the regenerative blower is provided with a damper or the like. Without blocking 50, air is attracted from the regenerative blower 49 by the air flow B of the blower 34, and the air flow B can be prevented from flowing back from the regenerative blower 49 and flowing out of the main body. Furthermore, since the blowing flow B blown from the blower by the attraction assisting means 57 is expanded to the entire blowing path 44, the blowing flow B flows into the entire dehumidifying means 36, and the dehumidification of the blowing flow is performed efficiently.
[0056]
As described above, according to the present embodiment, even when performing the dehumidifying mode and the regeneration mode, it can be configured only by the blower without providing the air path switching drive means such as a damper, so that the cost can be reduced easily. In addition, the vibration and durability during driving of the vehicle can be realized with higher reliability than a configuration using a damper.
[0057]
Example 4
FIG. 15 is an enlarged cross-sectional view in the vicinity of the ventilation path in the dehumidification mode in Example 4 of the present invention, and FIG. 16 is an enlarged cross-sectional view in the vicinity of the ventilation path in the regeneration mode. In the present embodiment, in the configuration of the first embodiment, the blower outlet of the blower is provided with the expanding means 59 that expands the flow of air from the blower 34 and narrows the suction port 50 of the regenerative blower 49. . In addition, the thing of the same code | symbol as Example 1 and Example 2 has the same structure, and abbreviate | omits description.
[0058]
In the above configuration, in the regeneration mode in which the ability of the dehumidifying means 36 is regenerated, the blower 34 is stopped and the heating means 42 and the regenerative blower 49 are driven as shown in FIG. When the dehumidifying means is heated by the heating means, the water vapor adsorbed on the dehumidifying means is desorbed. The desorbed water vapor A is discharged from the outlet of the regeneration fan 49 to the outside of the sheet body 31 by the regeneration fan 49.
[0059]
Next, in the dehumidifying mode in which dry air is blown out from the spout 40 and blown to the human body, the heating means 42 and the regenerative blower 49 are stopped and the blower 34 is driven as shown in FIG. Since the blast flow B blown out from the blower 34 by the magnifying means 59 is expanded to the entire air passage 44, the blast flow flows into the entire dehumidifying means 36, and the dehumidification of the blast flow is performed efficiently. In addition, since the suction port of the regenerative blower 49 faces the downstream side of the air flow B of the blower by the expanding means, even if the regenerative blower 49 and the blower 34 are separated, the suction of the regenerative blower 49 by a damper or the like The air C is attracted from the regenerative blower 49 by the air flow B of the blower 34 without blocking the mouth 50, and the air flow B can be prevented from flowing back from the regenerative blower 49 and flowing out of the sheet body 31.
[0060]
【The invention's effect】
As described above, according to the air-conditioning seat device of the present invention, the suction port of the regenerative blower faces the blower outlet of the blower, so that a damper for switching the air path and opening and closing is not necessary. In this way, the power consumption can be reduced because the damper is simpler and cheaper than the configuration with the damper and does not require the damper driving power. In addition, it is not necessary to consider the reliability that the damper is deformed due to the vibration of the car and stops operating.
[0061]
In this way, the dry air blown out from the spout evaporates the sweat on the body surface, giving the body a heat of vaporization and giving a cool feeling to the human body. It is possible to have a comfortable seating feeling.
