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は、以下の第一の従来例がある（例えば特許文献１参照）。すなわち、第１の従来例の図１２に示すように座席本体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を前記座席本体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としては以下の内容が開示されている（例えば特許文献２参照）。第二の従来例の図１３、図１４、図１５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。なお、空気乾燥装置１２は、図１４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。
【０００６】
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１５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。
【０００７】
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。
【０００８】
また、吸着材を用いて連続的に吸着再生を行う第三の実施例としてとして、さらに示すような装置がある（例えば特許文献３参照）。これは図１６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離し、湿り空気Ａ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Ｂ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。
【０００９】
しかし、上記従来の構成では、水分を脱離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３１の温度が高くなり、乾燥空気３１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。
【００１４】
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、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。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、除湿と送風を交互に繰り返し連続運転が可能であるため、吸着材の再生中にも送風運転を行い冷涼感を下げない。さらに、吸着材の再生を短時間で行うことができるので、除湿運転を間欠運転させたとしても、座席に除湿空気を送る除湿運転をしていない時間が短いため、違和感のない冷涼感を有する空調座席装置を提供することを目的とする。
【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、車室内空気を送風するシロッコファン等の送風機と、前記送風機で送風された空気をシリカゲルやゼオライトや活性アルミナなどの吸着材からなる除湿手段と、除湿後の空気を車室内空気で冷却する熱交換器と、座席本体の表皮に設けられた空気を噴出する噴出口と、座席本体外に連通した排出路と、前記除湿手段を加熱する電気ヒーター等の加熱手段と、前記噴出口へ送風することを可能とする送風手段と、熱交換後の乾燥空気を前記噴出口に導く通風路と、前記通風路と排出路を切り替える切替手段と、除湿空気が前記噴出口から噴出させる除湿モード時は前記切替手段を閉じるとともに、前記除湿手段の除湿性能を回復させる再生モード時は前記切替手段を開くとともに前記加熱手段を動作させるものである。
【００１７】
上記発明によれば、除湿モード運転では切替手段を閉じる位置にし、送風機を駆動する。送風機によって０．２ｍ^３／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、ムレ感を防止する。
【００１８】
次に、除湿モード運転が終了した後は、除湿手段が除湿性能を回復させる再生モード運転を行う。切替手段によって排出路を開く位置にし、加熱手段を通電し、０．０１ｍ^３／分の流量で送風機を駆動させる。シリカゲルの吸着材の場合は吸着材が１２０℃まで加熱されると水蒸気が吸着材から脱離し始めるが、発生した水蒸気を送風機で排出路から車室内に放出させる。さらに、再生モード運転と同時に、噴出口へ送風することを可能とする送風手段によって、車室内の空気は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。その際体表面に吹き付けられた風により、ムレ感を防止し人体への冷涼感を下げないようにする。
【００１９】
【発明の実施の形態】
第１の発明は、送風手段と、前記送風手段から送風された空気を除湿する除湿手段と、除湿後の空気を冷却する熱交換器と、座席本体の表皮に設けられた空気を噴出する噴出口と、座席本体外に連通した排出路と、前記除湿手段を再生時に加熱する加熱手段と、熱交換後の乾燥空気を前記噴出口に導く通風路と、前記除湿手段を通過した空気を前記熱交換機側または前記排出路側に切り替える切替手段とを有し、前記切替手段により、除湿モード時は前記除湿手段を通過した空気を前記通風路に導き、再生モード時は前記加熱手段を動作させるとともに、前記除湿手段を通過した空気を前記排出路に導くもので、かつ空調座席装置において、前記熱交換器は前記除湿後の空気と車室内の空気との熱交換により前記除湿後の空気を冷却するものである。
【００２０】
そして、除湿モード運転では切替手段によって排出路を閉じる位置にし、送風機を駆動する。送風機によって０．２ｍ^３／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、ムレ感を防止する。
【００２１】
次に、除湿モード運転が終了した後は、除湿手段が除湿性能を回復させる再生モード運転を行う。切替手段によって排出路を開く位置にし、加熱手段を通電し、０．０１ｍ^３／分の流量で送風機を駆動させる。シリカゲルの吸着材の場合は吸着材が１２０℃まで加熱されると水蒸気が吸着材から脱離し始めるが、発生した水蒸気を送風機で排出路から車室内に放出させる。さらに、再生モード運転と同時に、噴出口へ送風することを可能とする送風手段によって、車室内の空気は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。その際体表面に吹き付けられた風により、ムレ感を防止し人体への冷涼感を下げないようにする。
【００２２】
また、除湿手段によって乾燥された空気は熱交換器によって冷却されて、通風路を通り座席表面に設けられた噴出口から吹出す構成となっているので、結露水の処理が必要ない。また、コンプレッサー方式と比べて構成が簡易なので安価につくることができる。また、除湿手段が再生されていれば送風機の電力のみで動作させることができるので電力の消費が少ない。
【００２３】
第２の発明は、送風手段と、前記送風手段から送風された空気を除湿する除湿手段と、空気冷却フィンと前記空気冷却フィンの熱を放熱する放熱フィンを備えた熱交換器と、前記除湿手段と前記熱交換器を結ぶ送風路と、前記放熱フィンの冷却を行う冷却空気送風手段と、座席本体の表皮に設けられた空気を噴出する噴出口と、熱交換後の乾燥空気を前記噴出口に導く通風路と、前記除湿手段を加熱する加熱手段と、座席本体外に連通した排出路と、前記除湿手段を通過した空気を前記送風路側または排出路側に切り替える第１の切替手段と、前記冷却空気送風手段で送風された空気を前記送風路側または前記排出路側に切り替える第２の切替手段を有し、前記第１の切替手段および前記第２の切替手段により、再生モード時は前記除湿手段を通過した空気を排出路に導くとともに、前記冷却空気送風手段で送風された空気を前記通風路に導き、除湿モード時は前記除湿手段を通過した空気を前記通風路に導くとともに前記冷却空気送風手段で送風された空気により前記熱交換器を冷却し、前記冷却空気送風手段で送風された空気を前記排出路に導くものである。
【００２４】
このようにして、第１の発明では３つの送風手段を備える必要があったが、２つの送風手段を備えるだけで同じモード運転ができる。このため、簡易な構成となり、制御方法も複雑にならない。また、部品点数が少なく安価とすることができる。
【００２５】
第３の発明は、特に請求項３に記載の第１の切替手段と第２の切替手段を一体で構成した風路切替手段を有し、前記風路切替手段により、前記除湿手段を通過した空気を送風路側に切り替えた場合は冷却空気送風手段で送風された空気を排出路側に切り替え、前記除湿手段を通過した空気を排出路側に切り替えた場合は冷却空気送風手段で送風された空気を送風路側に切り替えるようにしたものである。
【００２６】
このようにして、切替手段と風路切替手段を一体化させて構成することができるので、ダンパーなどの切替手段が１つ減らすことができる。
【００２７】
第４の発明は、除湿手段は加熱手段表面に吸着材を担持し除湿風路内に挿入したものである。
【００２８】
このようにして、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。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。
【００２９】
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、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。
【００３０】
【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。
【００３１】
（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は再生モードにおける座部の除湿ユニット等の断面図、図３は除湿モードにおける座部の除湿ユニット等の断面図である。図において、３１は座席本体、３２は座席本体の座部、３３は座席本体の背部、３４は車室内空気を送風するシロッコファン等の送風機、３５は送風機３４の動作時に車内の空気を吸い込む送風機吸込口、３６は湿気を吸着する吸着材、３７は前記送風機３４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チタシリケートやシリカゲルや活性アルミナなどの吸着材３６からなる除湿手段である。
【００３２】
３８は空気冷却フィン、３９は放熱フィン、４０は仕切板で、４１は熱交換器で上部に空気冷却フィン３８と下部に放熱フィン３９が仕切板４０に取り付けられ上下で空気の送風が可能に構成されている。４２は熱交換器４１の放熱フィン３９を車室内空気で強制冷却させる冷却ファン、４３は冷却ファン４２を駆動させたときに車室内空気を吸い込む冷却ファン吸込口、４４は冷却ファン４２が放熱フィン３９を冷却して吹き出す冷却ファン吹出口である。ここで、冷却ファン４２を動作させると、まず放熱フィン３９が冷却され、熱伝導で熱交換器４１の空気冷却フィン３８が仕切板４０を介して冷却される。これにより、除湿後の空気を空気冷却フィン３８に通して連続的に冷却することができる。なお、熱交換器４１は空気冷却フィン３８と放熱フィン３９を両側備えた構成としてアルミ押出材などを用いて一体成形でつくられる。
【００３３】
４５は座席の表皮、４６は座席本体の表皮４５に設けられた空気を噴出する噴出口、４７は熱交換後の乾燥空気を噴出口４６に導く通風路、４８は除湿手段３７の下流に設けて除湿手段３７を加熱する電気ヒーター等の加熱手段、４９は除湿手段３７から座席本体外に連通した除湿手段３７より下流に設けた排出路、５０は除湿手段３７を通過した空気を、排出路４９側または熱交換器４１側に切り替えるための切替手段である。
【００３４】
５１は除湿手段３７の除湿性能を回復させる再生モード時において、座席表面に送風を可能とする送風手段、５２は送風手段吸込口、５３は通風路４７の一部に開口部を設けて送風を通風路４７に流し込む送風手段吹出口である。また、送風手段吹出口５３は除湿運転の送風の際に送風手段から漏れないようにする誘引板５４が先端部に設けられている。
【００３５】
５５は送風機３４の回転数、冷却ファン４２の回転数、送風手段５１の回転数を制御して送風量の可変と切替手段５０の開閉動作を制御することのできる制御手段である。
【００３６】
上記構成において、まず、図２を用いて、除湿手段３７の除湿性能を回復させる再生モードの動作を説明する。制御手段５５によって、切替手段５０を垂直にして排出路４９を開く位置に設定し、加熱手段４８に通電し、送風機３４を駆動させ、制御手段５５によって回転数を送風量を、０．０２ｍ^３／分微弱風となるよう制御する。吸着材３６がシリカゲルの場合は、１２０℃まで加熱させると水蒸気が吸着材３６から脱離し始め、発生した水蒸気を送風機３４で排出路４９から車室内に放出させる。なお、切替手段５０によって除湿手段３７と熱交換器４１が熱的に遮断されているため加熱手段４８で発生した熱が熱交換器４１で奪われることなく効率的に除湿手段３７に伝わるので除湿手段３７の吸着材３６の再生時間が早くなる。
【００３７】
さらに、再生モード時には、送風手段５１を駆動させて、車室内空気を送風手段吸込口５２より吸込み、通風路４７に導かれ表皮の噴出口４６から吹き出し、人体背側面を流れるようにする。従って、体表面に吹き付けられた風により、ムレ感を防止し人体への冷涼感を下げないようにすることができる。
【００３８】
なお、送風機３４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５５を設けた構成においては、再生モード時における送風機３４の送風量を、０．０２ｍ^３／分の微弱風となるよう制御する。このとき、加熱手段４８を通電すると、空気は温度が１２０℃〜１４０℃となって除湿手段３７の吸着材３６に送られ、吸着材３６を加熱するとともに、吸着材３６から脱離した水蒸気を吹き飛ばし、除湿手段３７の吸着材の再生を短時間で行うことができる。
【００３９】
なお、除湿運転と吸着材の再生運転を交互に繰り返し、再生運転中には送風手段を駆動させて送風を通風路４７に導き、表皮の噴出口４６から吹き出し、全体としては除湿運転と送風運転を交互に繰り返す連続運転としているが、送風手段５１を設けずに除湿運転を間欠して行えば送風手段を設けないので安価にできる。
【００４０】
次に、車室内空気を除湿する除湿モードについて動作を説明する。図３に示すように、制御手段５５によって、切替手段５０を水平にして排出路４９を閉じる位置に設定し、送風機３４を駆動する。送風機によって０．２ｍ^３／分の流量で除湿手段３７に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は吸着材３６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）の高温低湿度の空気となる。次に、この高温低湿度の空気は熱交換器４１の上部に備えられた空気冷却フィン３８に導かれて冷却され（３７℃、２０％）の低湿度空気となって通風路４７に導かれ表皮の噴出口４６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。
【００４１】
なお、本実施例では、切替手段により、除湿モード時に排出路４９を閉じ、再生モード時に排出路４９を開く構成としたが、除湿モード時に通風路４７を開き、再生モード時に通風路４７を閉じる構成としても同様に動作が実現できることはいうまでもない。
【００４２】
なお、図４に室温３５℃湿度５５％ＲＨの室内で、０．２ｍ^３／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、０．２ｍ^３／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。
【００４３】
なお、本実施例では、両側にフィンを設けたアルミ押出材の熱交換器としたが、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。
【００４４】
また、本実施例では、熱交換器４１を冷却する冷却手段として冷却ファン４２を使用することによって車室内空気を強制的に熱交換器４１の下部に吹き付けて冷却させる構成で説明したが、収納空間の制約の範囲で熱交換器４１のサイズを大きくすることが可能であれば、冷却ファン４２を設けなくとも自然対流のみでも熱交換器４１は熱交換されて冷却されるのはいうまでもない。または、アルミダイキャストやマグネシウム合金といった材料で形成された座席のフレームなどの車載部品の一部を熱交換器として利用することによって、吸着材３６の吸着熱の熱容量によっては冷却ファン４２などの冷却手段を設けなくとも熱交換器４１は熱交換されて冷却される。また、熱交換器４１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配置構成すれば、冷却ファン４２などの冷却手段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。
【００４５】
以上のように、送風運転を可能とする送風手段５１を備えることにより、除湿手段を除湿性能の回復を行う再生運転中でも座席表面に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。そして、ムレ感を防止し人体への冷涼感を下げないようにすることができる。
【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、背部のみあるいは、他の車内の空間を利用して、１つの装置として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５、図６は本発明の実施例２の空調座席装置の断面図であり、図５は除湿モードにおける座部の除湿ユニット等の断面図、図６は再生モードにおける座部の除湿ユニット等の断面図である。なお、実施例１と同一符号のものは同一構造を有し、説明は省略する。
【００４８】
図５において、６０は除湿手段３７と熱交換器４１を結ぶ送風路で、５６は冷却空気送風手段５７で送風された空気を前記送風路６０側または前記排出路４９側に切り替える風路切替手段で、同時に吸着材３６を通過した空気を前記送風路６０側または排出路４９側に切り替えることができる。風路切替手段５６を水平状態とした位置では、送風機３４によって送風される空気を除湿手段３７から送風路６０、熱交換器４１の上側の空気冷却フィン３８、通風路４７に送風して座席表面の噴出口４６から乾燥空気を噴出させるとともに、冷却空気送風手段５７によって送風される空気を熱交換器４１の下側の放熱フィン３９から排出路４９に放出する。また、ほぼ垂直状態とした位置では、加熱手段４８に通電し除湿手段３７を加熱して、送風機３４によって送風される空気により、除湿手段の湿気を排出路４９に放出するとともに、冷却空気送風手段５７によって送風される空気を放熱フィン３９、空気冷却フィン３８、通風路４７を通って噴出口４６に噴出するように送風を可能とする。
【００４９】
上記構成において、送風機３４で送風した空気を除湿する除湿モードでは、図５に示すように、制御手段５５によって、風路切替手段を水平状態とした位置にし、送風機３４を動作させて除湿手段３７に送風すると車室内の空気（３５℃、５５％ＲＨ）は、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）の高温低湿度の空気となり、送風路６０へ運ばれる。このとき送風路６０に備えられた風路切替手段５６は水平状態とした位置になっているため、高温低湿度の空気は熱交換器４１の上部に備えられた空気冷却フィン３８に導かれて熱交換される。次に空気冷却フィン３８が蓄えた熱は仕切板４０に伝わり、さらに熱交換器４１の下部に備えられた放熱フィン３９へと伝熱される。そして、放熱フィン３９に伝わった熱は、制御手段５５によって、冷却空気送風手段５７を動作させて車室内の空気を冷却空気送風手段吸込口５８より取り入れて、放熱フィン３９に送風し、送風路６０へ運ばれる。このとき送風路６０に備えられた風路切替手段５６は水平状態となって放熱フィン３９と排出路４９は連通するようになっているため、熱交換器４１の下側に設けられた放熱フィン３９の排熱は冷却空気送風手段５７によって排出路４９から放出される。これにより、放熱フィン３９は冷却されて、仕切板４０を介して上部の空気冷却フィン３８を常に冷却することになる。こうして、空気冷却フィン３８を通過した高温低湿度の空気は冷却され（３７℃、２０％）の低湿度空気となって通風路４７に導かれ表皮の噴出口４６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。

次に、除湿手段３７の能力を回復させる再生モードでは、図６のように風路切替手段をほぼ垂直状態とした位置にし、冷却空気送風手段５７によって車室内の空気を冷却空気送風手段吸込口５８から吸込みまれ、吸い込まれた空気は熱交換器４１の下部に備えられた放熱フィン３９を通過し、送風路６０へと導かれる。、そして送風路６０に設けられた風路切替手段５６がほぼ垂直状態となって送風路６０を遮蔽しているため、冷却空気送風手段５７で送風された空気は放熱フィン３９を通過し、風路切替手段５６によってＵターンして熱交換器４１の上側に備えられた空気冷却フィン３８を通過し、通風路４７に導かれ噴出口４６から噴出される。一方、加熱手段４８に通電し除湿手段３７を加熱するとともに送風機３４を動作させて、除湿手段の湿気を排出路４９に放出し、除湿手段の除湿性能を回復させる。
【００５１】
そして、実施例１のように送風手段を追加しなくても、除湿手段の再生モード中に座席表面に送風させることができる。
【００５２】
なお、本実施例では、風路切替手段５６のように１つのダンパーのみを備える構成としたが、図７に示すように、除湿手段３７を通過した空気を送風路６０側または排出路４９側に切り替える第１の切替手段５０ａと、冷却空気送風手段で送風された空気を排出路４９側または送風路６０側に切り替える第２の切替手段５０ｂの２つダンパーを設けて、冷却空気送風手段を座席表面の噴出口に送風するように構成することも可能である。
【００５３】
（実施例３）
図８は、本実施例３の空調ユニットの断面図、図９は除湿手段の斜視図、図１０は電気抵抗発熱体を構成する基材の断面図である。実施例１、２と異なるのは、除湿手段に加熱手段を一体に組み込んだ除湿加熱手段を用いた点であり、本実施例では、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としている。
【００５４】
図９、図１０に示すように、除湿加熱手段６１は、電気抵抗発熱体６２を形成する基材６３の表面にアンダーコート６５を施し、吸着材３６が担持されている。従って、再生時において加熱手段である電気抵抗発熱体６２の熱が直接吸着材３６に伝わり吸着材３６の昇温速度が速くなる。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除湿加熱手段６１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３６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。
【００５５】
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、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。
【００５６】
なお、図１１は基材６３としてエキスパンドメタルを用いた除湿手段の展開図であり、他に基材としてはパンチングメタルを用いてもよい。６２は基材６３をヒーターとして構成した電気抵抗発熱体で、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６５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３６を担持させて構成したものである。
【００５７】
この構成により、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３６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全面に接触するように溶接した給電端子６４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。
【００５８】
このようにして、エキスパンドメタルやパンチングメタルのように特別な加工を必要としない汎用な材料を基材として用い、電気抵抗発熱体として直接通電させることにより加熱手段としてりようすることができ、安価に構成できる。
【００５９】
また、電気抵抗発熱体６２の表面にアンダーコート６５を施し、アンダーコート６５の表面に吸着材３６を担持することにより、吸着材３６の担持が容易となり、剥がれにくくなる。また、金属などの電気抵抗発熱体と吸着材の熱膨張の違いで発生する剥がれ、脱離という問題は、アンダーコート材料自体が柔軟性材料であるため膨張収縮しても、アンダーコートが緩和させてアンダーコート表面に担持した吸着材が剥がれることを防ぐ。そして、吸着材の脱離による吸着性能の劣化がなく耐久性能が向上する。
【００６０】
また、図９のように電気抵抗発熱体を波板状に、折り曲げ加工することにより、平面状では長尺となる電気抵抗発熱体を小さくすることができ、除湿手段の小型化が計れる。また、除湿風路内では外気の通過面積当たりの吸着材との接触面積を増大することになるため、小型の除湿手段であるにもかかわらず、優れた吸着性能が実現できる。また、使用できる消費電力に規定がある場合などでは、折り曲げするターン数によって電気抵抗発熱体の長さを適宜調整できるので抵抗値を規格範囲内に設定することも容易である。
【００６１】
このようにして、吸着性能が高く、安価で、メンテナンスフリ−で、また環境負荷の小さいといった優れた点を有する。またチタン含有のゼオライトであるチタシリケート、シリカゲル、活性アルミナでは、吸着した後の再生モード時の再生温度を１２０℃程度と低く設定することができるため、加熱手段の消費電力を小さく抑えることができる。
【００６２】
【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、再生モード運転と同時に、噴出口へ送風することを可能とする送風手段によって、車室内の空気は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。その際体表面に吹き付けられた風により、顕熱を奪い、ムレ感を防止し人体への冷涼感を下げないようにする。そして、除湿モード運転では、噴出口から吹出した低湿度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、常に人体は冷涼感を得ることができる。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]
As this type of conventional air-conditioning seat device, there is the following first conventional example (see, for example, Patent Document 1). That is, as shown in FIG. 12 of the first conventional example, the seat body 1 is provided with an air bag 3 that forcibly sucks outside air through a portion of the skin cloth 2 corresponding to a portion where the back of the human body of the seat body 1 abuts. A dehumidifying and drying device 6 including a cooling dehumidifier 4 and a heating dryer 5 that dehumidify and dry the outside air taken in by the air bag 3 and exhausted to the back of the human body through the air bag 3 is incorporated in the headrest. The dehumidifying and drying device 6 and the air bag 3 are communicated 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 following content is disclosed as the air-conditioning seat apparatus of the 2nd prior art example which uses a hygroscopic material (for example, refer patent document 2). As shown in FIGS. 13, 14, and 15 of the second conventional example, the backrest portion 9 has an air passage 10 therein, and a water vapor partial pressure gradient is provided between the backrest portion 9 and the air passage 10. Accordingly, a moisture permeable layer 11 having both non-breathability and moisture permeability is disposed, and water vapor that is permeable 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. . As shown in FIG. 14, 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. .
[0006]
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 shown by a broken line, the heater 22 is energized to regenerate the adsorbing material 18 in the reaction vessel 16 and the air flowing through the reaction vessel 15 into the adsorbing material 17. It is dried by the hygroscopic action. Further, as shown in FIG. 15, the fan 23 may be disposed in the vicinity of the vehicle interior outlet 19.
[0007]
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.
[0008]
Further, as a third embodiment in which adsorption regeneration is performed continuously using an adsorbent, there is an apparatus as further shown (for example, see Patent Document 3). As shown in FIG. 16, 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 A. 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 B, and can dehumidify high-humidity air continuously.
[0009]
However, in the above-described conventional configuration, the heat of the adsorbent 24 where the moisture is desorbed and regenerated is transferred to the dehumidified portion, so that the temperature of the dry air 31 is increased, and the dry air 31 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.
[0014]
Also, in the case of a rotor type that rotates a cylindrical adsorbent molded into a corrugated or honeycomb shape to perform dehumidification operation and regeneration of the adsorbent, the adsorbent heat of the desorbed part is dehumidified Therefore, the temperature of the dry air becomes high, and the dry air is not suitable for a device that obtains a cool feeling. 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. 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-mentioned conventional problems, and since dehumidification and blowing can be alternately and continuously operated, the blowing operation is performed even during regeneration of the adsorbent, and the cool feeling is not lowered. Further, since the adsorbent can be regenerated in a short time, even if the dehumidifying operation is intermittently performed, the time when the dehumidifying operation for sending the dehumidifying air to the seat is short is short, so that it has a cool feeling without a sense of incongruity. It aims at providing an air-conditioning seat device.
[0016]
[Means for Solving the Problems]
In order to solve the conventional problem, a blower such as a sirocco fan that blows air in the vehicle interior, a dehumidifying means that is made of an adsorbent such as silica gel, zeolite, or activated alumina, and the air blown by the blower, Heat such as a heat exchanger that cools the air with vehicle interior air, a spout for ejecting air provided in the skin of the seat body, a discharge passage communicating with the outside of the seat body, and an electric heater that heats the dehumidifying means Means, air blowing means that allows air to be blown to the jet outlet, a ventilation path that guides the dry air after heat exchange to the jet outlet, a switching means that switches between the ventilation path and the discharge path, and dehumidified air In the dehumidifying mode for ejecting from the jet outlet, the switching means is closed, and in the regeneration mode for recovering the dehumidifying performance of the dehumidifying means, the switching means is opened and the heating means is operated. It is.
[0017]
According to the above invention, in the dehumidifying mode operation, the switching means is set to the closed position and the blower is driven. 0.2m by blower ³ 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.
[0018]
Next, after the dehumidifying mode operation is completed, a regeneration mode operation is performed in which the dehumidifying means recovers the dehumidifying performance. Switch to the position to open the discharge path with the switching means, energize the heating means, 0.01m ³ The blower is driven at a flow rate of / min. In the case of an adsorbent made of silica gel, when the adsorbent is heated to 120 ° C., water vapor begins to desorb from the adsorbent, but the generated water vapor is released from the discharge path into the vehicle compartment by a blower. Furthermore, the air in the vehicle compartment is guided to the ventilation path and blown out from the spout of the epidermis and flows on the back side of the human body by the air blowing means that allows air to be blown to the spout at the same time as the regeneration mode operation. At that time, the wind blown on the body surface prevents the feeling of stuffiness and does not lower the coolness of the human body.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
First The invention includes a blowing means, a dehumidifying means for dehumidifying the air blown from the blowing means, a heat exchanger for cooling the air after dehumidification, and a jet outlet for jetting air provided on the skin of the seat body. A discharge path communicating with the outside of the seat body, a heating means for heating the dehumidifying means at the time of regeneration, a ventilation path for guiding the dry air after heat exchange to the jet outlet, and the air passing through the dehumidifying means for the heat exchanger Switching means for switching to the discharge path side or the discharge path side, the switching means guides the air that has passed through the dehumidification means to the ventilation path in the dehumidification mode, operates the heating means in the regeneration mode, and The air that has passed through the dehumidifying means is guided to the discharge path. In the air conditioning seat device, the heat exchanger cools the air after dehumidification by heat exchange between the air after dehumidification and the air in the passenger compartment. .
[0020]
And in dehumidification mode driving | operation, it sets to the position which closes a discharge path by a switching means, and drives a fan. 0.2m by blower ³ 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.
[0021]
Next, after the dehumidifying mode operation is completed, a regeneration mode operation is performed in which the dehumidifying means recovers the dehumidifying performance. Switch to the position to open the discharge path with the switching means, energize the heating means, 0.01m ³ The blower is driven at a flow rate of / min. In the case of an adsorbent made of silica gel, when the adsorbent is heated to 120 ° C., water vapor begins to desorb from the adsorbent, but the generated water vapor is released from the discharge path into the vehicle compartment by a blower. Furthermore, the air in the vehicle compartment is guided to the ventilation path and blown out from the spout of the epidermis and flows on the back side of the human body by the air blowing means that allows air to be blown to the spout at the same time as the regeneration mode operation. At that time, the wind blown on the body surface prevents the feeling of stuffiness and does not lower the coolness of the human body.
[0022]
Further, since the air dried by the dehumidifying means is cooled by the heat exchanger and blows out from the jet outlet provided on the seat surface through the ventilation path, it is not necessary to treat the condensed water. In addition, since the configuration is simple compared to the compressor method, it can be manufactured at low cost. Further, if the dehumidifying means is regenerated, it can be operated only by the power of the blower, so that power consumption is small.
[0023]
Second The invention of the present invention comprises a blowing means, a dehumidifying means for dehumidifying the air blown from the blowing means, a heat exchanger provided with a heat dissipating fin for radiating heat from the air cooling fins and the air cooling fins, and the dehumidifying means, An air passage connecting the heat exchangers, cooling air blowing means for cooling the heat radiation fins, a jet port for jetting air provided on the skin of the seat body, and dry air after heat exchange to the jet port A ventilation path that leads, a heating means that heats the dehumidifying means, a discharge path that communicates with the outside of the seat body, a first switching means that switches the air that has passed through the dehumidifying means to the air blowing path side or the discharge path side, and the cooling There is a second switching means for switching the air blown by the air blowing means to the blowing path side or the discharge path side, and the dehumidifying means is operated in the regeneration mode by the first switching means and the second switching means. Through In the dehumidification mode, the air that has passed through the dehumidifying means is guided to the ventilation path and the cooling air blowing means is used to guide the air to the exhaust path. Blown air By Cooling the heat exchanger The air blown by the cooling air blowing means It leads to the discharge path.
[0024]
In this way First In the invention, it is necessary to provide three air blowing means, but the same mode operation can be performed only by providing two air blowing means. For this reason, it becomes a simple structure and the control method is not complicated. In addition, the number of parts can be reduced and the cost can be reduced.
[0025]
Third In particular, the present invention has air path switching means in which the first switching means and the second switching means according to claim 3 are integrally formed, and the air passing through the dehumidifying means by the air path switching means. When switched to the air passage side, the air blown by the cooling air blowing means is switched to the discharge path side, and when the air passed through the dehumidifying means is switched to the discharge path side, the air blown by the cooling air blowing means is moved to the air passage side. It is to be switched.
[0026]
In this way, since the switching means and the air path switching means can be integrated, the number of switching means such as a damper can be reduced by one.
[0027]
4th According to the invention, the dehumidifying means carries an adsorbent on the surface of the heating means and is inserted into the dehumidifying air passage.
[0028]
In this way, since the adsorbent is supported on the surface of the heating means such as the electric resistance heating element, the heat of the heating means is directly transferred to the adsorbent during regeneration, and the temperature rising 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. Further, since the adsorbent is directly heated, the air is hardly heated and the regenerative power is small.
[0029]
In addition, even if left for a long period of time, the dehumidifying means can be immediately regenerated, eliminating the need for a strict seal configuration to prevent the adsorption of water vapor in the atmosphere and a configuration that rotates a cylindrical adsorbent. Miniaturization of the unit can be realized.
[0030]

Embodiments of the present invention will be described below with reference to the drawings.

Heating means such as an electric heater for heating the dehumidifying means 37; 49, a discharge path provided downstream from the dehumidifying means 37 communicating with the outside of the seat body from the dehumidifying means 37; 50, a discharge path for air that has passed through the dehumidifying means 37; Switching means for switching to the 49 side or the heat exchanger 41 side.
[0034]
Reference numeral 51 denotes a blowing unit that enables air to be blown to the seat surface in the regeneration mode for restoring the dehumidifying performance of the dehumidifying unit 37, 52 is a blowing unit suction port, and 53 is an opening provided in a part of the ventilation path 47 for blowing air. It is a blower outlet that flows into the ventilation path 47. In addition, the blower outlet 53 is provided with an attracting plate 54 at its tip so as not to leak from the blower during the dehumidifying operation.
[0035]
55 is a control means that can control the rotation amount of the blower 34, the rotation speed of the cooling fan 42, and the rotation speed of the blower means 51 to control the change of the blower amount and the opening / closing operation of the switching means 50.
[0036]
In the above configuration, first, the operation in the regeneration mode for restoring the dehumidifying performance of the dehumidifying means 37 will be described with reference to FIG. The control means 55 sets the switching means 50 to a vertical position to open the discharge passage 49, energizes the heating means 48, drives the blower 34, and the control means 55 sets the rotation speed to the air flow rate of 0.02 m. ³ Control the wind to be weak per minute. When the adsorbent 36 is silica gel, water vapor begins to be detached from the adsorbent 36 when heated to 120 ° C., and the generated water vapor is discharged from the discharge passage 49 into the vehicle compartment by the blower 34. Since the dehumidifying means 37 and the heat exchanger 41 are thermally shut off by the switching means 50, the heat generated by the heating means 48 is efficiently transferred to the dehumidifying means 37 without being taken away by the heat exchanger 41. The regeneration time of the adsorbent 36 of the means 37 is shortened.
[0037]
Further, in the regeneration mode, the air blowing means 51 is driven so that the air in the passenger compartment is sucked from the air blowing means suction port 52, led to the ventilation passage 47, blown from the spout 46 of the epidermis, and flows on the back side of the human body. Accordingly, it is possible to prevent the feeling of stuffiness and the coolness of the human body from being lowered by the wind blown on the body surface.
[0038]
In the configuration in which the motor of the blower 34 is a direct current motor and the control means 55 for controlling the number of revolutions is provided, the amount of air blown by the blower 34 in the regeneration mode is set to 0.02 m. ³ Control the wind to be weak per minute. At this time, when the heating means 48 is energized, the air becomes 120 ° C. to 140 ° C. and is sent to the adsorbent 36 of the dehumidifying means 37 to heat the adsorbent 36 and remove water vapor desorbed from the adsorbent 36. It is possible to blow off and regenerate the adsorbent of the dehumidifying means 37 in a short time.
[0039]
The dehumidification operation and the adsorbent regeneration operation are alternately repeated. During the regeneration operation, the air blowing means is driven to guide the air flow to the air passage 47 and blown out from the spout 46 of the epidermis. However, if the dehumidifying operation is performed intermittently without providing the air blowing means 51, the air blowing means is not provided, so that the cost can be reduced.
[0040]
Next, operation | movement is demonstrated about the dehumidification mode which dehumidifies vehicle interior air. As shown in FIG. 3, the control means 55 sets the switching means 50 to a horizontal position to close the discharge path 49 and drives the blower 34. 0.2m by blower ³ The air in the passenger compartment (35 ° C., 55% RH) sent to the dehumidifying means 37 at a flow rate of / min is adsorbed by the adsorbent 36 to reduce the humidity and generate heat due to the adsorption heat (65 ° C., 3% RH). ) High temperature and low humidity air. Next, this high-temperature and low-humidity air is converted into air cooling fins provided at the upper part of the heat exchanger 41 38 Then, the air is cooled (37 ° C., 20%) as low-humidity air, led to the air passage 47, blown from the spout 46 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.
[0041]
In this embodiment, the switching means is configured to close the discharge path 49 in the dehumidification mode and open the discharge path 49 in the regeneration mode. However, the ventilation path 47 is opened in the dehumidification mode and the ventilation path 47 is closed in the regeneration mode. Needless to say, the same operation can be realized in the configuration.
[0042]
In FIG. 4, the room temperature is 35 ° C. and the humidity is 55% RH, 0.2 m ³ 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 ³ When air with a temperature of 31 ° C. and a humidity of 75% was ejected, the same cool feeling as that of 38 ° C. and 20% dry air was obtained.
[0043]
In this embodiment, the heat exchanger of the aluminum extruded material provided with fins on both sides is used, but the base surfaces of the aluminum extruded material provided with fins on one side are overlapped with each other with a heat conductive material such as silicon grease. Even if they are bonded 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.
[0044]
In the present embodiment, the cooling fan 42 is used as a cooling means for cooling the heat exchanger 41 so as to forcibly blow the passenger compartment air to the lower part of the heat exchanger 41 to cool it. If it is possible to increase the size of the heat exchanger 41 within the range of space constraints, it goes without saying that the heat exchanger 41 is cooled by heat exchange even by natural convection without providing the cooling fan 42. Absent. Alternatively, by using a part of an in-vehicle component such as a seat frame formed of a material such as aluminum die cast or magnesium alloy as a heat exchanger, depending on the heat capacity of the adsorption heat of the adsorbent 36, the cooling fan 42 or the like can be cooled. Even if no means is provided, the heat exchanger 41 is heat-exchanged and cooled. Further, if the heat exchanger 41 is arranged and configured to blow the air blown from an air conditioner such as an air conditioner, the heat exchanger can be effectively cooled without adding cooling means such as a cooling fan 42. Needless to say, you can.
[0045]
As described above, by providing the air blowing means 51 that enables the air blowing operation, the dehumidifying means can be blown to the seat surface even during the regeneration operation in which the dehumidifying performance is restored, so the dehumidifying operation and the air blowing operation are alternately repeated. The wind can be continuously sent to the seat surface as a whole. Further, it is possible to prevent a feeling of stuffiness and not to lower the coolness to the human body.
[0046]
In addition, although it demonstrated by the case where one apparatus was each integrated in a back part and a seat part like the seat apparatus of FIG. 1, only one seat part, only a back part, or the space in another vehicle is used, As a device, 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]

5 and 6 are cross-sectional views of the air-conditioning seat device according to the second embodiment of the present invention. FIG. 5 is a cross-sectional view of the seat dehumidifying unit and the like in the dehumidifying mode. FIG. FIG. In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
[0048]
In FIG. 5, 60 is an air passage connecting the dehumidifying means 37 and the heat exchanger 41, 56 is an air passage switching means for switching the air blown by the cooling air blow means 57 to the air passage 60 side or the exhaust passage 49 side. Thus, the air that has passed through the adsorbent 36 at the same time can be switched to the blower passage 60 side or the discharge passage 49 side. At the position where the air passage switching means 56 is in a horizontal state, the air blown by the blower 34 is blown from the dehumidifying means 37 to the air passage 60, the air cooling fins 38 on the upper side of the heat exchanger 41, and the air passage 47. The dry air is ejected from the nozzle 46 and the air blown by the cooling air blowing means 57 is discharged from the heat dissipating fins 39 below the heat exchanger 41 to the discharge passage 49. In a substantially vertical position, the heating means 48 is energized to heat the dehumidifying means 37, and the air blown by the blower 34 releases the moisture of the dehumidifying means to the discharge passage 49 and the cooling air blowing means. The air can be blown so that the air blown by 57 passes through the heat radiation fins 39, the air cooling fins 38, and the ventilation passage 47 and is jetted to the jet outlet 46.
[0049]
In the above configuration, in the dehumidifying mode in which the air blown by the blower 34 is dehumidified, as shown in FIG. 5, the control means 55 places the air path switching means in the horizontal state and operates the blower 34 to remove the dehumidifying means 37. When the air is blown into the air, the air in the passenger compartment (35 ° C., 55% RH) is adsorbed with water vapor to lower the humidity and generate heat due to the heat of adsorption (65 ° C., 3% RH). Carried to. At this time, since the air passage switching means 56 provided in the air passage 60 is in the horizontal position, the high-temperature and low-humidity air is guided to the air cooling fins 38 provided in the upper portion of the heat exchanger 41. Heat exchanged. Next, the heat stored in the air cooling fins 38 is transferred to the partition plate 40 and further transferred to the radiation fins 39 provided at the lower part of the heat exchanger 41. Then, the heat transmitted to the heat radiating fins 39 is operated by the control means 55 to operate the cooling air blowing means 57 so that the air in the passenger compartment is taken in from the cooling air blowing means suction port 58 and blown to the heat radiating fins 39. To 60. At this time, the air path switching means 56 provided in the air passage 60 is in a horizontal state so that the heat radiation fin 39 and the discharge path 49 are in communication with each other, so that the heat radiation fin provided on the lower side of the heat exchanger 41. The exhaust heat 39 is released from the exhaust passage 49 by the cooling air blowing means 57. As a result, the radiation fins 39 are cooled, and the upper air cooling fins 38 are always cooled via the partition plate 40. Thus, the high-temperature and low-humidity air that has passed through the air cooling fins 38 is cooled (37 ° C., 20%) as low-humidity air, led to the ventilation path 47, blown out from the spout 46 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.
[0050]
Next, in the regeneration mode in which the ability of the dehumidifying means 37 is restored, the air passage switching means is brought into a substantially vertical position as shown in FIG. 6, and the air in the vehicle compartment is cooled by the cooling air blowing means 57. The air sucked from 58 passes through the radiation fins 39 provided in the lower part of the heat exchanger 41 and is guided to the air blowing path 60. Since the air passage switching means 56 provided in the air passage 60 is in a substantially vertical state and shields the air passage 60, the air blown by the cooling air air blowing means 57 passes through the radiating fins 39, and the wind The path switching means 56 makes a U-turn, passes through the air cooling fins 38 provided on the upper side of the heat exchanger 41, is guided to the ventilation path 47, and is ejected from the ejection port 46. On the other hand, the heating means 48 is energized to heat the dehumidifying means 37 and the blower 34 is operated to release the moisture of the dehumidifying means to the discharge passage 49 and restore the dehumidifying performance of the dehumidifying means.
[0051]
And even if it does not add a ventilation means like Example 1, it can be made to air on the seat surface during the reproduction | regeneration mode of a dehumidification means.
[0052]
In this embodiment, only one damper is provided as in the air path switching means 56. However, as shown in FIG. 7, the air passing through the dehumidifying means 37 is supplied to the air passage 60 side or the discharge path 49 side. There are provided two dampers, a first switching means 50a for switching to air and a second switching means 50b for switching the air blown by the cooling air blowing means to the discharge path 49 side or the air blowing path 60 side. It is also possible to configure so as to blow air to the spout on the seat surface.

(Example 3)
FIG. 8 is a cross-sectional view of the air conditioning unit of the third embodiment, FIG. 9 is a perspective view of the dehumidifying means, and FIG. 10 is a cross-sectional view of the base material constituting the electric resistance heating element. The difference from the first and second embodiments is that a dehumidifying heating means in which a heating means is integrated into the dehumidifying means is used. In this embodiment, an adsorbent is supported on the surface of the heating means such as an electric resistance heating element. The configuration is as follows.
[0054]
As shown in FIGS. 9 and 10, the dehumidifying and heating means 61 applies an undercoat 65 to the surface of the base material 63 that forms the electric resistance heating element 62, and the adsorbent 36 is carried thereon. Accordingly, during regeneration, the heat of the electric resistance heating element 62 as heating means is directly transmitted to the adsorbent 36, and the temperature raising rate of the adsorbent 36 is increased. 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 the adsorption mode are repeated intermittently, the sufficient dehumidification capacity can be exhibited. Can be easily incorporated. Further, since the adsorbent 36 is directly heated, the air is hardly heated and the regenerative power is small.
[0055]
In addition, even if left for a long period of time, the dehumidifying means can be immediately regenerated, eliminating the need for a strict seal configuration to prevent the adsorption of water vapor in the atmosphere and a configuration that rotates a cylindrical adsorbent. Miniaturization of the unit can be realized.
[0056]
FIG. 11 is a development view of a dehumidifying means using expanded metal as the base 63, and punching metal may be used as the base. 62 is an electric resistance heating element comprising a base material 63 as a heater, and an undercoat 65 obtained by sintering and oxidizing aluminum hydroxide, cerium nitrate or the like is applied to an expanded metal surface such as stainless steel, zeolite, titasilicate, silica gel, active It is configured to carry an adsorbent 36 such as alumina.
[0057]
With this configuration, in the dehumidifying mode, the expanded metal mesh is open, so that the contact area with the adsorbent 36 is increased, and the pressure loss of the blower can be reduced because of the porous body. In the reproduction mode, the power feeding terminal 64 welded so as to be in contact with the entire surface of the expanded metal 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.
[0058]
In this way, a general-purpose material that does not require special processing such as expanded metal or punching metal can be used as a base material, and it can be used as a heating means by directly energizing it as an electric resistance heating element. Can be configured.
[0059]
Further, by applying the undercoat 65 to the surface of the electric resistance heating element 62 and supporting the adsorbent 36 on the surface of the undercoat 65, the adsorbent 36 can be easily carried and is not easily peeled off. In addition, the problem of peeling and detachment that occurs due to the difference in thermal expansion between the electric resistance heating element such as metal and the adsorbent is that the undercoat is relaxed even if it expands and contracts because the undercoat material itself is a flexible material. This prevents the adsorbent carried on the undercoat surface from peeling off. Further, the durability performance is improved without deterioration of the adsorption performance due to the desorption of the adsorbent.
[0060]
Further, by bending the electric resistance heating element into a corrugated plate as shown in FIG. 9, the electric resistance heating element that is long in the planar shape can be made smaller, and the dehumidifying means can be downsized. In addition, since the contact area with the adsorbent per passage area of the outside air is increased in the dehumidifying air passage, excellent adsorption performance can be realized in spite of the small dehumidifying means. In addition, when the power consumption that can be used is regulated, the length of the electric resistance heating element can be adjusted as appropriate depending on the number of turns to be bent, so that the resistance value can be easily set within the standard range.
[0061]
In this way, it has excellent points such as high adsorption performance, low cost, maintenance-free, and low environmental load. In addition, with titanium silicate, silica gel and activated alumina, which are titanium-containing zeolites, the regeneration temperature in the regeneration mode after adsorption can be set as low as about 120 ° C., so the power consumption of the heating means can be kept small. .
[0062]
【The invention's effect】
As described above, according to the air-conditioning seat device of the present invention, the air in the passenger compartment is guided to the ventilation path by the air blowing means that allows the air to be blown to the air outlet at the same time as the regeneration mode operation. Balloon, flowing on the back side of the human body. At that time, the wind blown on the body surface takes away sensible heat, prevents the feeling of stuffiness and prevents the coolness of the human body from being lowered. In dehumidifying mode operation, low-humidity air blown out from the spout evaporates sweat on the body surface, which gives heat to the human body, which cools the body and prevents stuffiness. Can be obtained. In particular, the seats in the vehicle in the summer can rapidly have a comfortable seating feeling.
