Description

【０００１】
【発明の属する技術分野】
本発明は、室内空気と室外空気との互いの熱エネルギーを交換しながら吸・排気する空調換気扇に関するものである。
【０００２】
【従来の技術】
図１４は、例えば特公昭６１−９２９９号公報に記載された従来の空調換気扇の構成図であり、この図において、１は本体ケーシング、１ａはこの本体ケーシング１の室外側壁面に設けられ、室外空気を吸い込む室外側吸込口、１ｂは本体ケーシング１の室外側壁面に設けられ、室内空気を吹出す室外側吹出口、２ａは本体ケーシング１の室内側壁面に設けられ、（外気）を吹出す室内側吹出口、２ｂは本体ケーシング１の室内側壁面に設けられ、室内空気を吸い込む室内側吸込口、Ａは室外側吸込口１ａと室内側吹出口２ａとを連通して室外空気を室内に給気する給気風路、Ｂは室外側吹出口１ｂと室内側吸込口２ｂとを連通して室内空気を室外に排気する排気風路であり、これらの風路Ａ，Ｂは熱交換器４を介して互いに交差し、該熱交換器４で互いの空気の保有熱を熱交換している。
【０００３】
また、５は給気風路内に設けられ、室外空気を室内に給気する給気送風機、６は排気風路内に設けられ、室内空気を室外に排気する排気送風機、７はこれら給気送風機５及び排気送風機６を駆動する電動機である。
【０００４】
次に、この動作について説明する。
まず、電源が入れられ、給気送風機５及び排気送風機６が駆動されると、給気送風機５の駆動によって室外側吸込口１ａから吸い込まれた室外空気が、熱交換器４を介して給気風路を通り、室内側吹出口２ａから室内へ吹出される一方、排気送風機６の駆動によって室内側吸込口２ｂから吸い込まれた室内空気は、熱交換器４を介して排気風路を通り、室外側吹出口１ｂから室外へ吹出される。
【０００５】
なお、この時、熱交換器４で室外空気と室内空気とは熱交換され、互いに保有する温・湿度の授受を行うので、冬場の温・湿度が低い室外空気は温・湿度が高い室内空気によって、温・湿度共に上げられ、その後給気送風機５の送風容量に対応した新鮮な空気が室内に給気されると共に、この給気送風量とほぼ同一の汚れた室内空気が排気送風機６によって室外に排気される。
【０００６】
また逆に、夏場の温・湿度が高い室外空気は温・湿度が低い室内空気によって、温・湿度共に下げられ、その後給気送風機５の送風容量に対応した新鮮な空気が室内に給気されると共に、この給気送風量とほぼ同一の汚れた室内空気が排気送風機６によって室外に排気される。
【０００７】
このように、従来の空調換気扇では、給気送風機５又は排気送風機６の送風容量のいずれか一方に対応した空気量のみが順次置換され、室内空気を換気するものであった。
【０００８】
【発明が解決しようとする課題】
以上説明したように、従来の空調換気扇では、給気送風機又は排気送風機のいずれか一方の送風容量の対応した空気量のみが順次置換され、室内空気を換気するため、例えば、タバコ等で室内空気が急激に汚れも、スピーデイに換気することができないという問題点があった。
【０００９】
この発明は係る問題点を解決するためになされたもので、室内空気がタバコ等で急激に汚れても、スピーデイに排出して室内空気をきれいにする空調換気扇を得ることを目的とする。
【００１０】
また、風路切換操作が簡単に行える使い勝手の良い空調換気扇を得ることを目的とする。
【００１１】
また、風路切換を行った時、送風量が自動的に切換わり、換気スピードが向上した使い勝手が良く、信頼性の高い空調換気扇を得ることを目的とする。
【００１２】
【課題を解決するための手段】
本発明の空調換気扇は、本体ケーシング内に設けられ、熱交換器を介して互いに交差する給気及び排気風路と、これら給気及び排気風路内のそれぞれに設けられ、それぞれの空気を給気・排気する給気・排気送風機と、を具備した空調換気扇において、前記給気及び排気風路の互いの風路がそれぞれ固定風路部と移動風路部とからなり、前記移動風路部が、前記固定風路部から切離されて所定の位置まで移動した時、該移動風路部の給気風路部が排気風路部として機能して室内空気を室外へ排出するように構成したものである。

【００１６】
また、レールが、前記本体ケーシングの床面に設けられ、前記車輪部を案内するものである。
【００１７】
また、前記移動風路部の底面の下方側に設けられ、該風路部を移動する移動手段と、この移動手段の移動方向の側面に設けられ、該側面の垂直方向に可変する弾性材からなる爪部と、前記本体ケーシングの床面に設けられ、前記移動手段の移動方向に長い長穴と、この長穴の長手方の側面に設けられ、前記爪部と係合する前切欠部と、を具備し、前記爪部が前記前切欠部に係合することにより、前記移動風路部が前記固定風路部に接合するものである。
【００１８】
また、後切欠部が、前記長穴の長手方の同一側面に前記前切欠部から所定の位置に設けられ、前記爪部と係合することにより、前記移動風路部が前記固定風路部から所定の位置に切離されるものである。
【００１９】
また、前記固定風路部及び前記移動風路部との互いの接合部がテーパ形状をなし、該テーパ形状の面で互いに接合させることにより、前記固定風路部と前記移動風路部とを接続させるものである。
【００２０】
また、前記固定風路部及び前記移動風路部との互いの接合部のいずれか一方が凹形状をなし、他方が凸形状をなし、該凹凸形状を嵌合させることにより、前記固定風路部と前記移動風路部とを接続させるものである。
【００２１】
また、制御部が、前記移動風路部が所定の位置に移動された時、前記給気送風機及び前記排気送風機を駆動するものである。
【００２２】

【００２３】
また、給気フィルタ及び排気フィルタが、前記固定風路部の切離部の開口に設けられたものである。
【００２４】
【発明の実施の形態】
実施の形態１．
図１は、この発明の実施の形態１における空調換気扇の風路切換前の断面図であり、図２は風路切換後の断面図である。
これらの図において、１は本体ケーシング、１ａはこの本体ケーシング１の室外側壁面（背面）に設けられ、室外空気を吸い込む室外側吸込口、１ｂは本体ケーシング１の室外側壁面（背面）に設けられ、室内空気を吹出す室外側吹出口、２ａは本体ケーシング１の室内側壁面に設けられ、（外気）を吹出す室内側吹出口、２ｂは本体ケーシング１の室内側壁面に設けられ、室内空気を吸い込む室内側吸込口、Ａは室外側吸込口１ａと室内側吹出口２ａとを連通して室外空気を室内に給気する給気風路、Ｂは室外側吹出口１ｂと室内側吸込口２ｂとを連通して室内空気を室外に排気する排気風路であり、これらの風路Ａ，Ｂは熱交換器４を介して互いに交差し、該熱交換器４で互いの空気の温・湿度を交換している。
【００２５】
また、５は給気風路内に設けられ、室外空気を室内に給気する給気送風機、６は排気風路内に設けられ、室内空気を室外に排気する排気送風機、７はこれら給気送風機５及び排気送風機６を駆動する電動機で、１１は給気風路内に設けられ、異物等を除去する給気フィルター、１２は排気風路内に設けられ、異物等を除去する排気フィルターである。
【００２６】
また、前述した給気風路Ａ，排気風路Ｂはいずれも固定風路部３と移動風路部９、即ち、給気風路Ａは固定給気風路部３ａと移動給気風路部９ａとからなり、排気風路Ｂは固定排気風路部３ｂと移動排気風路部９ｂとからなると共に、固定風路部３は熱交換器４を内蔵し、移動風路部９は送風機５，６を内蔵し、かつ本体ケーシング１の前後壁面に沿って移動する。
【００２７】
また、この移動風路部９の移動給気風路部９ａは、移動前に、本体ケーシングの室外側吸込口１ａと対向して連通した外気連通口９ｃを有すると共に、移動後に、本体ケーシング床又は天井等に設けられた第２の室内側吸込口１５と連通する室内連通口９ｄを有して室内と連通する構造になっている。
なお、移動給気風路部９ａの外気連通口９ｃ及び室内連通口９ｄは、図１に示すように、移動給気風路部９ａの吸込チャンバー室に設け、その吸込チャンバー室に設けても良いし、吸込チャンバー室を設けず、図５，６に示されるように、移動給気風路部９ａに直接設けても良い。
【００２８】
また、本体ケーシング１は、移動風路部９が移動できるようにするための空間Ｈを有し、かつ、その本体ケーシングの床又は天井には室内空気を吸込むための第２の室内側吸込口１５を有している。
【００２９】
次に、この動作について説明する。
まず、移動風路部９が移動されずに、固定風路部３と接続された状態で電源が入れられると、図１、３に示すように、給気送風機５の駆動によって室外空気が室外側吸込口１ａから吸い込まれ、熱交換器４を介して給気風路Ａを通り、室内空気と熱交換され、室内側吹出口２ａから室内へ吹出される一方、排気送風機６の駆動によって室内空気は室内側吸込口２ｂから吸い込まれ、熱交換器４を介して排気風路Ｂを通り、室外空気と熱交換され、室外側吹出口１ｂから室外へ吹出される。
【００３０】
即ち、室外空気と室内空気とは熱交換器４で熱交換され、互いに保有する温・湿度の授受を行いながら換気されるので、特に冬場においては、温・湿度が低い室外空気は温・湿度が高い室内空気によって、温・湿度共に上げられ、その後給気送風機５によって室内に給気される。一方、室内空気は温・湿度共に下げられ、排気送風機６によって室外に排気される。
【００３１】
また逆に、夏場においては、温・湿度が高い室外空気は温・湿度が低い室内空気によって、温・湿度共に下げられ、その後給気送風機５によって室内に給気される。一方、室内空気は温・湿度共に上げられ、排気送風機６によって室外に排気され、同一送風容量の給気送風機５又は排気送風機６に対応した空気量が順次置換され、室内空気を換気する。
【００３２】
次に、移動風路部９が移動手段（例えば、移動用電動機構、或いは、後述する図９のつまみ部２３とスリット穴２１の組み合わせ等）によって本体ケーシング１の前後壁面に沿って左右方向（この場合右方向）に移動され、固定風路部３から切り離されると、図２、４に示すように、本体ケーシングの室外側吸込口１ａと対向して連通した外気連通口９ｃが本体ケーシング１の背面によって塞がれると共に、今まで（即ち、移動前まで）本体ケーシング１の壁面（床又は天井等）で塞がれていた室内連通口９ｄが本体ケーシング１の床又は天井等に設けられた第２の室内側吸込口１５と連通し、室内と連絡され、その結果、移動給気風路９ａ及び移動排気風路９ｂ吹出口が、固定風路部３と移動風路部９の切離し部を介して室外側吸込口１ａと室外側吹出口１ｂとに連絡される。
【００３３】
次に、この状態で電源が入れられ、給気送風機５及び排気送風機６が駆動されると、第２の室内側吸込口１５及び室内側吸込口２ａから吸い込まれた室内空気は移動風路部９の切離し部を介して室外側吸込口１ａ及び室外側吹出口１ｂとから室外に吹出される。
即ち、移動前まで給気風路として機能していた移動給気風路９ａが排気風路として機能するようになる。
【００３４】
なお、この時、固定風路部３の固定給・排気風路部３ａ、３ｂの開口に給・排フィルター１１，１２をそれぞれ設けると、フィルターが抵抗物体となり、室内空気が固定風路部３へ流れなくなるため、室内側吸込口１５及び室内側吸込口２ａから吸い込まれた室内空気の大部分は移動風路部９の切離し部を介して室外側吸込口１ａ及び室外側吹出口１ｂからスムースに室外に吹出されることになる。
【００３５】
以上説明したように、本体ケーシング内に設けられ、熱交換器を介して互いに交差する給気及び排気風路と、これら給気及び排気風路内のそれぞれに設けられ、それぞれの空気を給気・排気する給気・排気送風機と、を具備した空調換気扇において、前記給気及び排気風路がそれぞれ固定風路部と移動風路部からなり、前記移動風路部が前記固定風路部から切離されて所定の位置まで移動した時、該移動風路部の給気風路部が排気風路部として機能して室内空気を室外へ排出するので、移動排気風路部と共に移動給気風路部が室内空気を室外へ排出するようになるため、室内空気がタバコ等で急激に汚れても、スピーデイに排出して室内空気をきれいする空調換気扇が得られる。
【００３６】
なお、この時、前述したように、移動風路部が本体ケーシングの前後壁面に沿って給気・排気送風機と共にスライドすることによって前記固定風路部から切離されて所定の位置まで移動するように構成すると、本体ケーシングの前後の幅を広くすることなく、移動風路部の給気風路部が排気風路部として機能して室内空気を室外へ排出するようになるため、薄型タイプの排気量が向上した空調換気扇が得られる。
【００３７】
実施の形態２．
この実施の形態２においては、図５，６に示すように、ファンケーシングである移動通風路９を本体ケーシング１の前後壁面間で回転させることにより、移動風路部９の移動給気風路部９ａを排気風路部として機能させるものであり、なお、このものは、移動通風路９に本体ケーシング１の室外側吸込口１ａと対向して連通した外気連通口９ｃを有すると共に、回転移動後に、本体ケーシング１の天井等に設けられた第２の室内側吸込口１５と連通する室内連通口９ｄとを有する構造になっており、また、本体ケーシング１には、移動風路部９が回転できるための空間Ｈを有し、かつ、その本体ケーシングの天井には室内空気を吸込むための第２の室内側吸込口１５を有し、かつ、本体ケーシング１内には室内連通口９ｄを閉じるためのケーシング塞ぎ板１９を有する構造になっている。
なお、その他の構成は実施の形態１とほぼ同じである。
【００３８】
次に、この動作について説明する。
まず、ファンケーシングである移動風路部９が回転されずに、固定風路部３と接続された状態で電源が入れられると、図５に示すように、給気送風機５の駆動によって室外空気が室外側吸込口１ａから吸い込まれ、熱交換器４を介して給気風路を通り、室内空気と熱交換され、室内側吹出口２ａから室内へ吹出される一方、排気送風機６の駆動によって室内空気は室内側吸込口２ｂから吸い込まれ、熱交換器４を介して排気風路を通り、室外空気と熱交換され、室外側吹出口１ｂから室外へ吹出される。
なお、この時、移動給気風路９ａの室内連通口９ｄはケーシング塞ぎ板１９で塞がれているため、室内連通口９ｄから室内空気は吸引されない。
【００３９】
次に、ファンケーシングである移動風路部９のみが本体ケーシング１の前後壁面間で回転され、固定風路部３から切り離されると、図６に示すように、固定風路部３の接続風路開口部は移動風路部９の特にファンケーシング壁面で塞がれ、本体ケーシング１の室外側吸込口１ａと対向して連通していた外気連通口９ｃも本体ケーシング１の背面（後面）によってほぼ塞がれ、今まで（即ち、回転前まで）本体ケーシング１の塞ぎ板１９で塞がれていた室内連通口９ｄが本体ケーシング１の天井に設けられた第２の室内側吸込口１５と連通し、室内と連絡され、その結果、移動給気風路９ａ及び移動排気風路９ｂの吹出口が本体ケーシング１のバイパス空間を介して室外側吸込口１ａと室外側吹出口１ｂとに連絡される。
【００４０】
次に、この状態で電源が入れられ、給気送風機５及び排気送風機６が駆動されると、第２の室内側吸込口１５及び室内側吸込口２ａから吸い込まれた室内空気は回転後のファンケーシング吹出口（移動風路部の吹出口）を介して室外側吸込口１ａ及び室外側吹出口１ｂとから室外に吹出される。
即ち、回転前まで給気風路として機能していた移動給気風路９ａが排気風路として機能するようになる。
【００４１】
以上説明したように、ファンケーシングである移動風路部のみを本体ケーシングの前後壁面間で回転することによって前記固定風路部から切離されて所定の位置まで移動するように構成して、移動給気風路を排気風路として機能させるようにしたので、本体ケーシングの前後の幅を広くすることなく、また、移動風路部内の給・排気送風機を動かすことなく、給気風路部を排気風路部として機能させて室内空気を室外へ排出するようになるため、更に使い勝手が良く、薄型タイプの排気風量が向上した空調換気扇が得られる。
【００４２】
実施の形態３．
この実施の形態３においては、実施の形態１に、図７、８に示すように、移動風路部９の底面部に車輪部２０を追加して設けると共に、本体ケーシング１の床面に車輪部２０を支えて案内するレール２１を追加して設けたものである。
【００４３】
次に、この動作について説明する。
まず、移動風路部９の底面部に車輪部２０を設けるだけで、移動風路部９の底面と本体ケーシングの床面との摩擦抵抗が軽減されるため、移動風路部９を移動する時に、簡単に移動できるようになるが、更に、この車輪部２０を案内するレール２１を本体ケーシング１の床面に設けると、移動風路部９を固定風路部３から切離し、その後再び移動して固定風路部３と接続するような時にも、固定風路部３に対して常にレール２１を介して位置決めがなされているので、確実に接続されるようになる。
【００４４】
以上説明したように、移動風路部の底面部に車輪部を設けると、移動時の風路部と本体ケーシングの床面との摩擦抵抗を軽減するため、簡単にスムースに移動できる空調換気扇が得られる。
【００４５】
また更に、車輪部を案内するレールを本体ケーシングの床面に設けると、レールが固定風路部に対して移動風路部の位置を決めるため、スムースに移動ができ、繰り返し確実に風路が接続される信頼性の高い空調換気扇が得られる。
【００４６】
なお、上記実施例では、摩擦抵抗を減らすのに車輪２１を用いたが、摩擦抵抗の小さい材料で一体成形するか、もしくは潤滑剤を用いても良い。
【００４７】
実施の形態４．
この実施の形態４においては、実施の形態１に、図９、１０に示すように、移動風路部９の底面の下方側に設けられ、該移動風路部を移動する移動手段としてのつまみ部（突起部）２３と、このつまみ部２３の移動方向の側面に設けられ、該側面の垂直方向に可変するプラスチック等の弾性材からなる爪部２３ａと、本体ケーシング１の床面に設けられ、つまみ部（突起部）２３が挿入される左右（移動）方向に長いスリット穴２４、即ち、長穴２４と、この長穴２４の長手方の同一側面に所定位置に設けられ、爪部２３ａと係合する前切欠部２４ａ及び前切欠部２４ｂと、を追加したものである。
【００４８】
次に、この動作について図１０，１１を用いて説明する。
まず、移動風路部９が固定風路部３に接続された状態では、図１０に示すように、つまみ部２３の爪部２３ａがスリット穴２４の前切欠部２４ａに挿入された状態となる。
【００４９】
次に、移動風路部９が固定風路部３から切離され、移動されると、図１１に示すように、爪部２３ａが押され、爪部２３ａの高さを低くして切欠部２４ａから解除し、つまみ部２３がスリット穴２４に沿って移動されて所定の位置に来ると、即ち、移動風路部９が移動されて所定の位置に来ると、爪部２３ａの押え付け力を解除し、爪部２３ａのバネ力によってつまみ部２３がスリット穴２４に固定される。
【００５０】
なお、この時、移動風路部９の固定状態を更に確実にするために、爪部２３ａが所定の位置に設けられた後切欠部２４ｂで解除され、該後切欠部２４ｂに挿入されるようにすると、移動風路部９が更に安定した状態で固定される。
【００５１】
その後再び、移動風路部９と固定風路部３とを接続する時は、爪部２３ａの押え付けながら、つまみ部２３を移動し、爪部２３ａの押え付け力を前切欠部２４ａで解除して、爪部２３ａを前切欠部２４ａに挿入する。
【００５２】
以上説明したように、移動風路部の底面の下方側に設けられ、該風路部を移動する移動手段と、この移動手段の移動方向の側面に設けられ、該側面の垂直方向に可変する弾性材からなる爪部と、本体ケーシング１の床面に設けられ、前記移動手段の移動方向に長い長穴と、この長穴の長手方の側面に設けられ、前記爪部と係合する前切欠部と、を具備し、移動風路部と固定風路部との接合位置関係を規制したので、移動風路部と固定風路部との接合が確実に行なわれ、接合時の空気漏れが防止された信頼性の高い空調換気扇が得られる。
【００５３】
また、後切欠部が、前記長穴の長手方の同一側面に前記前切欠部から所定の位置に設けられ、前記爪部と係合して移動風路部と固定風路部との切離し距離を規制したので、移動風路部と固定風路部との切離し距離が適性に確保されるため、切離し時の風路未確保が防止された信頼性の高い空調換気扇が得られる。
【００５４】
実施の形態５．
この実施の形態５においては、実施の形態１から４における固定風路部３と移動風路部９との接合構造を、図１２、１３に示すように、互いの接合面をテーパ形状にして接合したり、或いは互いに嵌合する形状にして接合したりしたものである。
【００５５】
なお、このように、固定風路部３及び移動風路部９との互いの接合部のいずれか一方が凹形状をなし、他方が凸形状をなすようにして、該凹凸形状を嵌合させることにより、固定風路部３と移動風路部９とを接続させると、固定風路部３と移動風路部９との接合部からの給気及び排気空気の漏れが少くなるため、給・排気を確実に行う信頼性の高い空調換気扇が得られる。
【００５６】
特に、接合部をテーパ形状にして接合するようにすると、固定風路部と移動風路部との接合時に、互いの位置が若干ズレても、スムースに接合するようになるため、空気漏れを防止して給・排気を確実に行う使い勝手の良い空調換気扇が得られる。
【００５７】
実施の形態６．
この実施の形態６においては、実施の形態１から４において、移動風路部９を固定風路部３から切離し、移動風路部９が移動された所定の位置、即ち、移動給気風路９ａとして機能していた風路が排気風路として機能するような位置にセットされた時、位置確認機構としてのスイッチ等からの信号に基づいて制御部（図示せず）が給気送風機５及び排気送風機６を駆動するものである。
【００５８】
なお、このようにすると、給・排気するための運転スイッチを作動させることなく、給気送風機５及び排気送風機６を駆動して排気できるようになるため、運転スイッチ作動有無に起因するトラブルが防止できると共に、使い勝手の良い空調換気扇が得られる。
【００５９】
また、給気送風機５及び排気送風機６の送風量を強、中、弱のノッチで制御し、即ち、送風機の回転数を変え、送風量を変化させるものにおいては、給気風路として機能していた移動給気風路９ａが排気風路として機能するような位置にセットされた時に、制御部（図示せず）が各送風機５，６の回転数を上限値で回転させるようにすると、給・排気送風機が室内空気をその最高風量で排気するようになるため、スピーデイに汚れた室内空気を換気する使い勝手の良い空調換気扇が得られる。
【００６０】
【発明の効果】
以上説明したように本願発明によれば、本体ケーシング内に設けられ、熱交換器を介して互いに交差する給気及び排気風路と、これら給気及び排気風路内のそれぞれに設けられ、それぞれの空気を給気・排気する給気・排気送風機と、を具備した空調換気扇において、前記給気及び排気風路の互いの風路がそれぞれ固定風路部と移動風路部とからなり、前記移動風路部が、前記固定風路部から切離されて所定の位置まで移動した時、該移動風路部の給気風路部が排気風路部として機能して室内空気を室外へ排出するように構成したので、移動排気風路部と共に移動給気風路部が室内空気を室外へ排出するようになるため、室内空気がタバコ等で急激に汚れても、スピーデイに排出して室内空気をきれいする排気風量が向上した空調換気扇が得られる。。
【００６１】
また、前記移動風路部が、前記本体ケーシングの前後壁面に沿って前記給気及び排気送風機と共にスライドすることによって前記固定風路部から切離されて所定の位置まで移動するように構成されたので、本体ケーシングの前後の幅（奥行き）を広くすることなく、給気風路部を排気風路部として機能させて室内空気を室外へ排出するようになるため、薄型タイプの排気風量が向上した空調換気扇が得られる。
【００６２】
また、前記移動風路部が、前記本体ケーシングの前後壁面に沿って前記給気及び排気送風機のファンケーシングのみを回転することによって前記固定風路部から切離されて所定の位置まで移動するように構成されたので、本体ケーシングの前後の幅を広くすることなく、また、移動風路部内の給・排気送風機を動かすことなく、給気風路部を排気風路部として機能させて室内空気を室外へ排出するようになるため、更に使い勝手が良く、薄型タイプの排気風量が向上した空調換気扇が得られる。
【００６３】
また、車輪部が、前記移動風路部の底面部に設けられ、前記本体ケーシングの床面を移動するので、移動時の風路部と本体ケーシングの床面との摩擦抵抗が軽減されるため、簡単にスムースに移動できる使い勝手の良い空調換気扇が得られる。
【００６４】

These air passages A and B intersect with each other via the heat exchanger 4. The humidity is changed.
[0025]
Reference numeral 5 denotes an air supply blower that is provided in the supply air passage and supplies outdoor air into the room, 6 is an exhaust air blower that is provided in the exhaust air passage and exhausts indoor air to the outside, and 7 is these supply air blowers. 5 and an electric motor that drives the exhaust blower 6, 11 is an air supply filter that is provided in the supply air passage and removes foreign matters, and 12 is an exhaust filter that is provided in the exhaust air passage and removes foreign matters and the like.
[0026]
Further, the above-described supply air passage A and exhaust air passage B are both from the fixed air passage portion 3 and the moving air passage portion 9, that is, the supply air passage A is formed from the fixed air supply air passage portion 3a and the moving air supply air passage portion 9a. The exhaust air passage B includes a fixed exhaust air passage portion 3b and a moving exhaust air passage portion 9b. The fixed air passage portion 3 includes a heat exchanger 4, and the moving air passage portion 9 includes the fans 5 and 6. It moves along the front and rear wall surfaces of the main casing 1.
[0027]
Further, the moving air supply air passage portion 9a of the moving air passage portion 9 has an outside air communication port 9c communicating with the outdoor suction port 1a of the main body casing before the movement, and after the movement, the main body casing floor or The indoor communication port 9d that communicates with the second indoor-side suction port 15 provided on the ceiling or the like has a structure that communicates with the room.
The outdoor air communication port 9c and the indoor communication port 9d of the moving air supply air passage portion 9a may be provided in the suction chamber chamber of the moving air supply air passage portion 9a as shown in FIG. Instead of providing the suction chamber, it may be provided directly in the moving air supply air passage portion 9a as shown in FIGS.
[0028]
Moreover, the main body casing 1 has a space H for allowing the moving air passage section 9 to move, and a second indoor side air inlet for sucking indoor air into the floor or ceiling of the main body casing 15.
[0029]
Next, this operation will be described.
First, when the power is turned on while the moving air passage portion 9 is not moved and is connected to the fixed air passage portion 3, the outdoor air is driven by the air supply blower 5 as shown in FIGS. The air is sucked in from the outside suction port 1a, passes through the air supply passage A via the heat exchanger 4, is exchanged with the room air, and blows out into the room from the room side air outlet 2a. Is sucked in from the indoor suction port 2b, passes through the exhaust air passage B via the heat exchanger 4, is exchanged with the outdoor air, and is blown out from the outdoor air outlet 1b.
[0030]
That is, the outdoor air and the indoor air are exchanged by the heat exchanger 4 and are ventilated while exchanging the temperature and humidity held by each other. Therefore, especially in winter, outdoor air with low temperature and humidity is temperature and humidity. Both the temperature and humidity are raised by the high indoor air, and then the air is supplied into the room by the air supply blower 5. On the other hand, the temperature and humidity of the room air are both lowered and exhausted to the outside by the exhaust fan 6.
[0031]
On the other hand, in summer, outdoor air having a high temperature / humidity is reduced in both temperature and humidity by indoor air having a low temperature / humidity, and then supplied to the room by an air supply blower 5. On the other hand, the room air is raised in both temperature and humidity, exhausted to the outside by the exhaust blower 6, and the air quantity corresponding to the supply blower 5 or the exhaust blower 6 having the same air blowing capacity is sequentially replaced to ventilate the room air.
[0032]
Next, the moving air passage portion 9 is moved in the left-right direction along the front and rear wall surfaces of the main casing 1 by moving means (for example, a moving electric mechanism or a combination of a knob portion 23 and a slit hole 21 in FIG. 9 described later). In this case, when it is moved to the right) and separated from the fixed air passage section 3, as shown in FIGS. 2 and 4, the outdoor air communication port 9c communicating with the outdoor suction port 1a of the main casing is opposed to the main casing 1 The indoor communication port 9d that has been blocked by the wall surface (floor or ceiling, etc.) of the main casing 1 until now (ie, before moving) is provided in the floor or ceiling of the main casing 1 and so on. The second indoor side air inlet 15 communicates with the room, and as a result, the moving air supply air passage 9a and the mobile exhaust air passage 9b are separated from the fixed air passage portion 3 and the moving air passage portion 9. Through the outdoor suction port 1a It is communicated to the outdoor side air outlet 1b.
[0033]
Next, when the power is turned on in this state and the air supply blower 5 and the exhaust blower 6 are driven, the indoor air sucked from the second indoor side suction port 15 and the indoor side suction port 2a is moved to the moving air passage portion. The air is blown out from the outdoor suction port 1a and the outdoor blower outlet 1b through the separation part 9.
In other words, the moving air supply air passage 9a that has functioned as the air supply air passage before the movement functions as the exhaust air passage.
[0034]
At this time, if the supply / exhaust filters 11 and 12 are respectively provided in the openings of the fixed supply / exhaust air passage portions 3a and 3b of the fixed air passage portion 3, the filter becomes a resistance object, and the room air becomes the fixed air passage portion 3 Therefore, most of the indoor air sucked in from the indoor side air inlet 15 and the indoor side air inlet 2a is smooth from the outdoor air inlet 1a and the outdoor air outlet 1b via the cut-off portion of the moving air passage portion 9. It will be blown out outdoors.
[0035]
As described above, the air supply and exhaust air passages provided in the main body casing and intersecting each other through the heat exchanger, and the air supply and exhaust air passages are provided in each of the air supply and exhaust air passages. -In an air-conditioning exhaust fan equipped with an air supply / exhaust fan for exhausting, the air supply and exhaust air passages are each composed of a fixed air passage portion and a moving air passage portion, and the moving air passage portion is from the fixed air passage portion. When separated and moved to a predetermined position, the supply air passage portion of the moving air passage portion functions as an exhaust air passage portion and discharges indoor air to the outside. Since the unit discharges the room air to the outside, an air-conditioning ventilation fan that discharges the room air quickly and cleans the room air even when the room air is abruptly contaminated with tobacco or the like can be obtained.
[0036]
At this time, as described above, the moving air passage portion slides along with the front and rear wall surfaces of the main body casing together with the air supply / exhaust blower so as to be separated from the fixed air passage portion and move to a predetermined position. With this configuration, the supply air passage portion of the moving air passage portion functions as an exhaust air passage portion and discharges indoor air to the outside without increasing the front and rear width of the main body casing. An air-conditioning ventilation fan with improved volume is obtained.
[0037]
Embodiment 2. FIG.
In the second embodiment, as shown in FIGS. 5 and 6, the moving air supply passage portion of the moving air passage portion 9 is rotated by rotating the moving air passage 9, which is a fan casing, between the front and rear wall surfaces of the main body casing 1. 9a functions as an exhaust air passage portion, and this has an outside air communication port 9c that communicates with the moving air passage 9 in opposition to the outdoor air inlet 1a of the main casing 1 and after the rotational movement. The main body casing 1 has a structure having an indoor communication port 9d communicating with the second indoor side suction port 15 provided on the ceiling or the like of the main body casing 1, and the main body casing 1 has a moving air passage portion 9 rotating. The main body casing has a second indoor side air inlet 15 for sucking indoor air, and the main body casing 1 closes the indoor communication port 9d. Case for It has a structure having a ring closing plate 19.
Other configurations are substantially the same as those of the first embodiment.
[0038]
Next, this operation will be described.
First, when the power is turned on while the moving air passage portion 9 that is a fan casing is not rotated and is connected to the fixed air passage portion 3, the outdoor air is driven by the air supply blower 5 as shown in FIG. Is sucked in from the outdoor suction port 1a, passes through the air supply air passage through the heat exchanger 4, exchanges heat with room air, and blows out into the room through the room side air outlet 2a. The air is sucked from the indoor suction port 2b, passes through the exhaust air passage through the heat exchanger 4, is heat-exchanged with the outdoor air, and is blown out from the outdoor air outlet 1b.
At this time, since the indoor communication port 9d of the moving air supply air passage 9a is closed by the casing closing plate 19, the indoor air is not sucked from the indoor communication port 9d.
[0039]
Next, when only the moving air passage portion 9 that is a fan casing is rotated between the front and rear wall surfaces of the main body casing 1 and separated from the fixed air passage portion 3, as shown in FIG. The road opening is blocked by the wall surface of the moving air passage 9, particularly the fan casing wall, and the outside air communication port 9 c that is in communication with the outdoor suction port 1 a of the main body casing 1 is also formed by the back surface (rear surface) of the main body casing 1. The indoor communication port 9d that has been substantially blocked and has been blocked by the closing plate 19 of the main casing 1 until now (that is, until before the rotation) is provided with the second indoor-side suction port 15 provided on the ceiling of the main casing 1. As a result, the air supply air passage 9a and the mobile exhaust air passage 9b are connected to the outdoor air inlet 1a and the outdoor air outlet 1b through the bypass space of the main body casing 1. The
[0040]
Next, when the power is turned on in this state and the supply blower 5 and the exhaust blower 6 are driven, the indoor air sucked from the second indoor suction port 15 and the indoor suction port 2a becomes the fan after rotation. The air is blown out from the outdoor air inlet 1a and the outdoor air outlet 1b through the casing air outlet (the air outlet of the moving air passage).
That is, the moving air supply air passage 9a that has functioned as the air supply air passage before the rotation functions as the exhaust air passage.
[0041]
As described above, only the moving air passage portion that is the fan casing is rotated between the front and rear wall surfaces of the main body casing so as to be separated from the fixed air passage portion and moved to a predetermined position. Since the supply air passage is made to function as an exhaust air passage, the supply air passage portion is exhausted without widening the front and rear width of the main body casing and without moving the supply / exhaust fan in the moving air passage portion. Since the indoor air is discharged outside the room by functioning as a road portion, an air-conditioning ventilator with improved usability and improved exhaust airflow is obtained.
[0042]

In addition, the air supply amount of the air supply blower 5 and the exhaust air blower 6 is controlled by strong, medium, and weak notches, that is, the one that changes the rotation amount of the blower and changes the air supply amount functions as an air supply air path. When the moving air supply air passage 9a is set to a position that functions as an exhaust air passage, the control unit (not shown) rotates the rotation speed of each of the blowers 5 and 6 at the upper limit value. Since the exhaust blower exhausts indoor air at the maximum air volume, a convenient air-conditioning ventilation fan that ventilates dirty indoor air quickly can be obtained.
[0060]
【The invention's effect】
As described above, according to the present invention, the air supply and exhaust air passages provided in the main body casing and intersecting each other via the heat exchanger, and the air supply and exhaust air passages are provided respectively. In the air-conditioning exhaust fan provided with the air supply / exhaust fan for supplying / exhausting the air, each air path of the air supply and exhaust air path is composed of a fixed air path part and a moving air path part, When the moving air passage portion is separated from the fixed air passage portion and moves to a predetermined position, the supply air passage portion of the moving air passage portion functions as an exhaust air passage portion and discharges indoor air to the outside. Since the moving air supply air passage portion and the moving air supply air passage portion discharge indoor air to the outside of the room, even if the indoor air suddenly gets dirty with cigarettes or the like, it is quickly discharged and the indoor air is discharged. Air-conditioning ventilation fan with improved exhaust air flow It is. .
[0061]
In addition, the moving air passage portion is configured to slide from the fixed air passage portion to a predetermined position by sliding together with the air supply and exhaust air blowers along the front and rear wall surfaces of the main body casing. Therefore, without increasing the front and rear width (depth) of the main body casing, the supply air passage portion functions as the exhaust air passage portion and exhausts the indoor air to the outside, thus improving the thin type exhaust air flow rate. An air-conditioning ventilation fan is obtained.
[0062]
Further, the moving air passage portion is separated from the fixed air passage portion and moves to a predetermined position by rotating only the fan casing of the air supply and exhaust blower along the front and rear wall surfaces of the main body casing. Therefore, without increasing the front and rear width of the main body casing, and without moving the supply / exhaust blower in the moving air passage, the air supply air passage functions as the exhaust air passage and Since it is discharged outside the room, it is possible to obtain an air-conditioning ventilation fan that is more convenient and has a thin type with improved exhaust air flow.
[0063]
In addition, since the wheel portion is provided on the bottom surface portion of the moving air passage portion and moves on the floor surface of the main body casing, frictional resistance between the air passage portion and the floor surface of the main body casing during movement is reduced. An easy-to-use air conditioning ventilator that can be moved easily and smoothly is obtained.
[0064]
In addition, since the rail is provided on the floor surface of the main casing and guides the wheel portion, the rail determines the position of the moving air passage portion with respect to the fixed air passage portion, so that the moving can be performed smoothly and repeatedly. A highly reliable air-conditioning ventilation fan that secures the air path is obtained.
[0065]
Also, a moving means provided on a lower side of the bottom surface of the moving air passage section, and a moving means for moving the air passage section, and an elastic material provided on a side surface in the moving direction of the moving means and variable in the vertical direction of the side face. A claw portion provided on the floor surface of the main body casing, a long hole that is long in the moving direction of the moving means, and a front notch portion that is provided on a longitudinal side surface of the long hole and engages the claw portion. When the claw portion engages with the front notch portion, the moving air passage portion is joined to the fixed air passage portion, so that the moving air passage portion and the fixed air passage portion are reliably joined. Thus, a highly reliable air-conditioning ventilation fan in which air leakage during joining is prevented can be obtained.
[0066]
In addition, a rear notch is provided at a predetermined position from the front notch on the same side surface in the longitudinal direction of the elongated hole, and the moving air passage portion is engaged with the claw portion so that the moving air passage portion is the fixed air passage portion. Since the separation distance between the moving air passage section and the fixed air passage section is adequately secured, a highly reliable air-conditioning ventilation fan that prevents unsecured air passage at the time of separation is obtained. It is done.
[0067]
In addition, the joint portion between the fixed air passage portion and the moving air passage portion has a tapered shape, and the fixed air passage portion and the moving air passage portion are connected to each other on the tapered surface. Since they are connected, they can be joined smoothly even if their positions are slightly misaligned, so that it is possible to obtain an easy-to-use air-conditioning ventilation fan that prevents air leakage and reliably supplies and exhausts air.
[0068]
Further, either one of the joint portions of the fixed air passage portion and the moving air passage portion has a concave shape, the other has a convex shape, and the concave and convex shapes are fitted to each other, so that the fixed air passage is fitted. Since the part and the moving air path part are connected to each other, leakage of air supply and exhaust air from the joint part is reduced, so that a highly reliable air-conditioning exhaust fan that reliably supplies and exhausts air is obtained.
[0069]
Further, since the control unit drives the air supply blower and the exhaust air blower when the moving air passage unit is moved to a predetermined position, the air supply can be performed without operating the operation switch for supplying and exhausting air. -Since the exhaust blower is driven to exhaust, a highly reliable air-conditioning ventilation fan that is easy to use and prevents troubles caused by the operation switch operation is obtained.
[0070]
In addition, the control unit changes the rotation speed of the air supply blower and the exhaust blower, and the rotation speed of each of the blowers is rotated at an upper limit value. Since the exhaust air is exhausted, a convenient air-conditioning fan that ventilates dirty indoor air on a speedy day can be obtained.
[0071]
Further, since the air supply filter and the exhaust filter are provided at the opening of the separation portion of the fixed air passage portion, the filter becomes a resistance object, and the indoor air does not flow to the fixed air passage portion, so that the indoor air is smoothly supplied. A highly reliable air-conditioning fan that is blown out outdoors can be obtained.
