Description

【０００１】
【発明の属する技術分野】
本発明は、壁体内に埋め込まれて設置される換気装置に関する。
【０００２】
【従来の技術】
近年、社会的な省エネルギー指向の高まりや、住環境の快適性の追求から、建物の高気密、高断熱化が進んでおり、このような建物に対する換気の必要性に伴い、種々の換気装置が求められ、特に居室の換気に関しては、冷暖房時のエネルギーロスを抑えるため、小風量で常時換気を行い、かつ室内の美観を損なわない壁埋め込み型の換気装置が要望されている。
【０００３】
従来、この種の換気装置の一例として図１２および図１３に示されるものがあった。
【０００４】
以下、その構成を図１２および図１３を参照しながら説明する。
【０００５】
図に示すように、内部に、ファン１０１と電動機１０２からなる室内の空気を室外に排気する送風機１０３と、室内側に室内側排気口１０４および室内側給気口１０５と、室外側に室外側排気口１０６および室外側給気口１０７と、室内側排気口１０４と室外側排気口１０６を送風機１０３を介して連通させる排気流路１０８と、室内側給気口１０５と室外側給気口１０７を連通させて室外の空気を室内に取り込む、排気流路１０８の外方に形成される給気流路１０９とを設けた箱体状の枠体１１０を設け、枠体１１０の室内側に排気用開口１１１と給気用開口１１２を設けたグリル１１３を設け換気装置を構成していた。
【０００６】
この換気装置を壁に取付施工するには、枠体１１０が挿入される矩形の壁穴１１４を、壁体を構成する室内側パネル１１５と室外側パネル１１６にそれぞれ開けるとともに、室内側パネル１１５と室外側パネル１１６の間に充填された断熱材１１８も壁穴１１４に合わせて切り取り、壁体を補強する補強枠１１７を壁穴１１４に嵌挿固定し、これに換気装置を取り付けていた。
【０００７】
【発明が解決しようとする課題】
このような従来の換気装置では、換気装置を取付施工するときには、室内側壁面に枠体が挿入できるような矩形の壁穴を開け、壁体内に枠体を納めてから、枠体の室内側端面の外周部に外方に向け形成されたフランジを壁面に当接させ、取付ねじでフランジと壁面を固定することになるが、矩形の壁穴の角部は強度が弱いため、壁体内に補強枠を設け、壁面を形成する室内側パネルを補強しなければならないという課題があった。
【０００８】
また、最近の高気密、高断熱化された建物には壁体内に十分に断熱材が設けられているが、枠体は壁体内に納められるため、その面積分は断熱材を切り取る必要があり、その面積が大きいほど建物の断熱効果が低下することになるという課題があった。
【０００９】
本発明は上記課題を解決するもので、壁体内に補強枠を設けないで、室内側パネルに取付施工ができるとともに、壁体内の断熱材を切り取る面積をできるだけ少なくし、断熱性の高い換気装置を提供することを目的とする。
【００１０】
【課題を解決するための手段】
本発明の換気装置においては、室内側と室外側にそれぞれ開口を設け、内部に２個の送風ファンを設けた枠体を備え、前記枠体を壁体内に納めて設置する換気装置において、前記枠体は、前記壁体の室内側壁面に設けられ、その左右両端部に円弧形状を有する補強枠を設けない壁穴に挿入設置され、前記枠体の左右端部は、前記壁穴の左右両端部に形成された円弧形状に沿うように挿入設置される形状を有した構成としたものである。
【００１１】
この本発明によれば、枠体が収納される室内側壁面の壁穴の左右端部が円弧形状を有するので、壁体内に、特に壁穴の角部を補強する補強枠を設けないで、室内側壁面に取付施工ができるとともに、従来の矩形の壁穴形状より壁体内の断熱材を切り取る面積をより少なくし、壁体内の非断熱面積をより小さくできる断熱性の高い換気装置を提供することができる。
【００１２】
【発明の実施の形態】
本発明の請求項１記載の発明は、室内側と室外側にそれぞれ開口を設け、内部に２個の送風ファンを設けた枠体を備え、前記枠体を壁体内に納めて設置する換気装置において、前記枠体は、前記壁体の室内側壁面に設けられ、その左右両端部に円弧形状を有する補強枠を設けない壁穴に挿入設置され、前記枠体の左右端部は、前記壁穴の左右両端部に形成された円弧形状に沿うように挿入設置される形状を有した構成としたものであり、枠体が収納される室内側壁面の壁穴の左右端部が円弧形状を有するので、壁体内に、特に壁穴の角部を補強する補強枠を設けないで、室内側壁面に取付施工ができるとともに、従来の矩形の壁穴形状より壁体内の断熱材を切り取る面積をより少なくし、壁体内の非断熱面積をより小さくして断熱性を高めることができるという作用を有する。
【００１３】
以下、本発明の実施の形態について、図１〜図１１を参照しながら説明する。
【００１４】
（実施の形態１）
図１および図２に示すように、室内側に室内側排気口１および室内側給気口２と、室外側に室外側排気口３および室外側給気口４とを設け、その左右端部の一端側の内部に、排気用ファン５を室内側に、給気用ファン６を室外側に仕切板１０で区画して配設し、排気用ファン５および給気用ファン６を１個の電動機７で駆動させるように設け、室内側排気口１と室外側排気口３を排気用ファン５を介して連通させる排気流路８と、室内側給気口２と室外側給気口４を給気用ファン６を介して連通させる給気流路９とを内部に設けた枠体１１と、枠体１１の室内側端面の外周には外方に向け突出する取付用フランジ１２と、取付用フランジ１２に、室内側から操作することで室内側パネル１７を取付用フランジ１２とで狭持する支持片２３を備えた固定手段２５と、排気用通風口１３および給気用通風口１４を備え、取付用フランジ１２に嵌合して枠体１１に取り付けられるグリル１５とを設け構成され、枠体１１は、その左右端部が円弧に沿ってほぼ内接するような多角形状に形成されている。
【００１５】
また、固定手段２５は、取付用フランジ１２に設けられ、室内側から緩締可能な取付ねじ２４と、取付ねじ２４に螺合され、取付ねじ２４を締めると、室内側に移動して室内側パネル１７を取付用フランジ１２とで狭持し、取付ねじ２４を緩めると、室外側に移動して狭持を解除する支持片２３とから構成される。
【００１６】
上記構成において、換気装置を取付施工するときは、まず、壁体１６の室内側壁面である室内側パネル１７を、枠体１１の外形に合わせ、枠体１１が挿入できるように壁穴１８を開ける。このとき壁穴１８を設ける手順は、まず、給気用ファン６の回転軸をほぼ中心とし、枠体１１の多角形状の左右端部外郭がほぼ内接するような大きさの半径である丸穴を室内側パネル１７に開け、さらに同じ丸穴を左右対称に開ける。そして、距離をおいて開けられたこの２個の丸穴の上端部同士を結んだ線を鋸刃等で切り、また、下端部同士を結んだ線も同様に切ればよい。こうすると、枠体１１の外形が内挿されるように左右端部に円弧状の曲線を有した壁穴１８を容易に開けることができる。
【００１７】
また、丸穴はサークルカッターやホールソーなどで簡単に開けられ、高所などの無理な姿勢で行われることが多い施工において、直線を切ることによって矩形の壁穴を開ける角穴施工と比べて、直線を切るという作業が少なく、作業が容易で、仕上がりが美しいものになる。特に、居室の室内側パネルに一般的に用いられる石膏ボードにおいては、その素材から円弧を有する壁穴をあけることが、強度や仕上がりという点で、非常に有効となる。
【００１８】
さらに、壁穴１８の左右端部を円弧形状とすることで、矩形状壁穴の角部の強度を補強する必要がなくなるに伴い、室内側パネル１７を補強する補強枠を設ける必要もなく、施工性が格段に向上する。
【００１９】
そして、室内側パネル１７に左右端部に円弧状の曲線を有した壁穴１８を開けた後、壁体１６内に設けられている断熱材１９を壁穴１８の形状に沿って切り取り、室外側パネル２０に、室外側排気口３と室外側給気口４に対応する丸穴の開口２１、２２をそれぞれ設け、枠体１１の室外側排気口３と室外側給気口４のそれぞれに室外と連通するダクト（図示せず）を接続して、枠体１１を壁穴１８に取付用フランジ１２が室内側パネル１７に当接するまで挿入する。
【００２０】
枠体１１を壁体１６に固定するには、取付用フランジ１２の前面に複数設けられた取付ねじ２４を締めることで、支持片２３が取付ねじ２４の回転方向に倒れて枠体１１に形成された凹部１１ａに当たり、それ以上回転せず保持されることになるので、取付ねじ２４をさらに締め続けると支持片２３は、取付ねじ２４に螺合されたまま室内側に移動することになり、支持片２３を室内側パネル１７の室外側端面に当接させて、室内側パネル１７を取付用フランジ１２とで狭持するまで締めればよい。
【００２１】
そして、枠体１１の室外側排気口３と室外側給気口４のそれぞれに連通するダクトにフード（図示せず）を設けると換気装置の施工が完了する。この換気装置を運転すると、排気ファン５と給気ファン６がともに回転し、室内側排気口１に対応する排気用通風口１３から室内の空気が吸い込まれ、排気流路８を通り、室外側排気口３、ダクト、開口２１を介してフードから室外に排気されるとともに、フードから室外の空気が吸い込まれ、ダクト、開口２２、室外側給気口４を介して給気流路９を通り、室内側給気口２に対応する給気用通風口１４から室内に給気される。
【００２２】
また、断熱材１９は、壁穴１８の形状に沿って切り取られるので、矩形の壁穴施工に対して、角部に相当する部分を切り取る必要がないため、壁体１６内の非断熱部分をより小さくすることができ、換気装置を取り付けることによる建物のエネルギーロスを低減することになる。
【００２３】
なお、枠体１１の左右端部の外形は、多角形状だけに限定されるものでなく、例えば、部分的に曲面部を有したり、大部分が曲面を有したりする形状でもよく、円弧に沿って内挿されるような形状であれば、その作用効果に差異はない。
【００２４】
このように本発明の実施の形態１の換気装置によれば、枠体１１が収納される室内側壁面である室内側パネル１７の壁穴１８の左右両端部が円弧形状であるので、壁体１６内に、特に壁穴１８の角部を補強する補強枠を設けないで、室内側壁面に取付施工ができるとともに、従来の矩形の壁穴形状より壁体１６内の断熱材１９を切り取る面積をより少なくし、壁体１６内の非断熱面積をより小さくできる断熱性の高い換気装置を提供することができる。
【００２５】
また、室内側から操作可能な固定手段２５を設けたので、着脱自在で、壁体１６を傷めることなく、アンカーナットなどの固定部品を設けなくてよい、施工が容易な換気装置を提供できる。
【００２６】
（実施の形態２）
図３に示すように、枠体１１Ａの室内側に、枠体１１Ａの取付フランジ１２Ａ近傍に設けた挿通孔１１ｂと、挿通孔１１ｂに挿入され、後方部２８を枠体１１Ａの外周に、前方部２７を枠体１１Ａの内側に位置させた弾性体の支持片２６とを有する固定手段２５Ａを設ける。
【００２７】
上記構成において、挿通孔１１ｂに挿入された弾性体の支持片２６の前方部２７を枠体１１Ａの内側に倒すと、山形状に湾曲させた後方部２８がその弾性力により室内側パネル１７の室外側に押し付けられ、室内側パネル１７を取付用フランジ１２Ａとで狭持することになり、枠体１１Ａが壁体１６に固定される。そして、枠体１１Ａの内側に倒された前方部２７は、枠体１１Ａに設けた係止部（図示せず）に係合されたり、枠体１１Ａにねじ固定されたりして元の位置に戻らないように固持されるので、後方部２８は室内側パネル１７を室内側に押圧する状態に維持されることになる。
【００２８】
このように本発明の実施の形態２の換気装置によれば、室内側から操作可能な固定手段２５Ａを設けたので、着脱自在で、壁体１６を傷めることなく、アンカーナットなどの固定部品を設けなくてよい、施工が容易な換気装置を提供できる。
【００２９】
（実施の形態３）
図４に示すように、枠体１１Ｂの内部に、室内側排気口１、排気用ファン５、室外側排気口３を順に経て形成される排気流路８と、室外側給気口４、給気用ファン６、室内側給気口２を順に経て形成される給気流路９とが交差する部分に熱交換素子２９を設ける。
【００３０】
上記構成において、熱交換換気を必要とする断熱性の高い建物に、この換気装置を取り付けるときには、実施の形態１と同様に、室外側パネル１７に、枠体１１Ｂが挿入できるように、枠体１１Ｂの外形より若干大きい、その左右端部に円弧形状を有する壁穴１８を開け、壁体１６内の断熱材１９を壁穴１８に沿った形状で切り取ることになり、矩形状の壁穴と異なり建物の非断熱部分を小さくすることができる。そして、室外側パネル（図示せず）に、室外側給気口４と室外側排気口３のそれぞれに対応する開口（図示せず）を設け、枠体１１Ｂの室外側排気口３および室外側給気口４に室外と連通させるダクト（図示せず）を設け、枠体１１Ｂを壁穴１８に挿入設置する。室外にはフード（図示せず）をダクトに設ける。
【００３１】
このように本発明の実施の形態３の換気装置によれば、熱交換素子２９を有する換気装置が取り付けられる熱交換換気の必要な断熱性の高い建物において、壁体１６内の断熱材１９の切り欠き面積を抑え、熱エネルギーロスを小さくした換気装置を提供できる。
【００３２】
（実施の形態４）
図５に示すように、枠体１１Ｃの左右端部を、壁穴１８の左右端部の円弧形状にほぼ内接して壁穴１８に挿入設置されるように、円弧状に形成する。
【００３３】
上記構成において、換気装置を壁体１６に取り付けるときは、実施の形態１と同様に、室内側パネル１７に、枠体１１Ｃの外形より若干大きい長丸形状の壁穴１８を開け、枠体１１Ｃを壁穴１８に取付用フランジ１２が室内側パネル１７に当接するまで挿入する。このとき、枠体１１Ｃの左右端部は、円弧形状であるので、壁穴１８の左右端部の円弧形状部分にほぼ内接した状態で壁体１６内に収納される。このため、枠体１１Ｃと壁穴１８の間の隙間がほとんどなくなり、取付用フランジ１２の、枠体１１Ｃから外方に突出した部分が、そのまま室内側パネル１７と換気装置との接触面積となり、これによって、室内の空気が壁体１６内に侵入するのを防止することになる。
【００３４】
このように本発明の実施の形態４の換気装置によれば、換気装置を室内側壁面である室内側パネル１７に設置時に、壁穴１８と枠体１１Ｃの隙間を小さくできるので、枠体１１Ｃ端部に形成される取付用フランジ１２と室内側パネル１７の接触面積を確保するために、取付用フランジ１２を外方に向けて大きくしなくても、壁体１６内の結露の原因となる室内空気の壁体１６内への侵入を防止できるとともに、室内側に露出する取付フランジ１２をより小さくでき、コンパクトで美観に優れた換気装置を提供することができる。
【００３５】
（実施の形態５）
図６に示すように、枠体１１の左右端部に、内部に排気用ファン５と、給気用ファン６と、これらを駆動させる電動機７とを設けた送風機ユニット３０をほぼ内接するように設ける。
【００３６】
上記構成において、送風機ユニット３０は、枠体１１の左右端部の内側面１１ｂとの隙間がなく、ほぼ接するように配設されることになる。
【００３７】
このように本発明の実施の形態５の換気装置によれば、送風機ユニット３０の外郭が、枠体１１の左右端部の内側面にほぼ接することになり、枠体１１の内部の左右のデッドスペースがなくなるため、枠体の幅寸法を小さくできるとともに、建物の非断熱面積をより小さくできる。
【００３８】
（実施の形態６）
図７に示すように、枠体１１Ｄの左右端部が、送風機ユニット３０Ａの外枠の約半分を形成するように送風機ユニット３０Ａを設ける。
【００３９】
上記構成において、送風機ユニット３０Ａの外枠の半分は、枠体１１Ｄで形成されるため、枠体１１Ｄは、換気装置の外郭であるとともに、送風機ユニット３０Ａのケーシングの機能を有することになる。
【００４０】
このように本発明の実施の形態６の換気装置によれば、枠体１１Ｄの左右端部が送風機ユニット３０Ａの外枠の約半分を兼ねることになり、枠体１１Ｄの内部の上下、左右のデッドスペースがなくなるため、より枠体の寸法を小さくできるとともに、建物の非断熱面積をさらに小さくできる。
【００４１】
（実施の形態７）
図８に示すように、枠体１１Ｅ内の左右両端部のそれぞれに排気用ファン５と、給気用ファン６とを配設する。
【００４２】
上記構成によって、壁体（図示せず）内に埋め込むことのできる枠体１１Ｅの高さに制限のある建物において、大風量の換気能力が必要なときには、ファン径を大きくすることによる枠体１１Ｅの大型化を行わずに、枠体１１Ｅ内のスペースを活用して大風量の換気を行うことができる。
【００４３】
なお、実施例は、排気用ファンと給気用ファンとを設けた同時給排気機能の換気装置であるが、２つのファンを同じ方向に配設することで排気専用や給気専用の大風量の換気装置とすることも可能で、その作用効果に差異がないことはいうまでもない。
【００４４】
このように本発明の実施の形態７の換気装置によれば、壁体内に埋め込むことのできる枠体１１Ｅの高さに制限のある建物において、枠体１１Ｅの高さを大きくせずに、風量を増加でき、換気能力の高い換気装置を提供できる。
【００４５】
（実施の形態８）
図９に示すように、枠体１１の室内側に、室内側排気口１と室内側給気口２のそれぞれを自在に開閉する室内側排気口シャッター３１と、室内側給気口シャッター３２とを設け、室内側排気口シャッター３１に設けられたシャッターレバー３８の往復直線運動と連動して室内側作動板３３が回動するに伴い、室内側排気口シャッター３１と室内側給気口シャッター３２が互いに逆向きに左右に往復直線運動するように、室内側排気口シャッター３１の下部と室内側給気口シャッター３２の上部をその間に設けた室内側作動板３３で連結する。また、枠体１１の室外側には、室外側排気口３と室外側給気口４のそれぞれを自在に開閉する室外側排気口シャッター３４と、室外側給気口シャッター３５とを設け、室内側作動板３３とそのほぼ中心部同士を連結棒３７で連結された室外側作動板３６が、室内側作動板３３の回動に連動して回動するに伴い、室外側排気口シャッター３４と室外側給気口シャッター３５が互いに逆向きに左右に往復直線運動するように、室外側排気口シャッター３４の上部と室外側給気口シャッター３５の下部をその間に設けた室外側作動板３６で連結する構成とした。
【００４６】
上記構成において、使用者が、取付用フランジ１２の下方に突出したシャッターレバー３８を左側に大きく移動させると、室内側排気口シャッター３１が左に移動するとともに、室内側作動板３３は時計回りに回動し、室内側給気口シャッター３２を右側に移動させ、室内側排気口１と室内側給気口２は開口される。さらに、室内側作動板３３の回動と連動して室外側作動板３６も時計回りに回動し、室外側排気口シャッター３４を右側に、室外側給気口シャッター３５を左側に移動させ、室外側排気口３と室外側給気口４は開口される。これに対して、シャッターレバー３８を右側に大きく移動させると、室内側作動板３３は反時計回りに回動し、これと連動して各構成要素は上記と逆の動きをして室内側排気口１、室内側給気口２、室外側排気口３、および室外側給気口４は閉鎖される。
【００４７】
このように本発明の実施の形態８の換気装置によれば、室内側排気口シャッター３１、室内側給気口シャッター３２、室外側排気口シャッター３４、および室外側給気口シャッター３５の閉鎖により、枠体１１内部に封印された空気が、断熱材の働きをして換気装置の停止時でも壁体の断熱を維持することができる。
【００４８】
（実施の形態９）
図１０および図１１に示すように、枠体１１Ｆの室外側開口であるところの室外側排気口３および室外側給気口４に、室外と連通するパイプ３９を一体に設け、パイプ３９の外周には複数の凹部４２を形成する。
【００４９】
上記構成において、換気装置を取付施工するときには、パイプ３９を室外側パネル２０の開口２１、２２に挿入して、枠体１１Ｆを壁穴１８に挿入設置する。このとき、風雨などの水の浸入や換気漏れを防ぐために、パイプと枠体の接続部や、パイプと壁体に設けた開口との隙間に、コーキング材を充填する必要があるが、枠体１１Ｆとパイプ３９は一体に形成されているので、コーキング材４０は、開口２１、２２とパイプの隙間にのみ施すだけでよい。そして、屋外には、パイプ３９を覆うように風雨防止のフード４１を設ける。また、パイプ３９の長さ調整をする必要のあるときは、パイプ３９の外周に形成された凹部４２に沿って適当な長さに切断すればよい。
【００５０】
このように本発明の実施の形態９の換気装置によれば、枠体１１Ｆにパイプ３９を一体に設けたので、枠体１１Ｆの室外側排気口３および室外側給気口４の外周面と、パイプ３９との結合部のシールをする必要がなく、確実な気密性が確保できるとともに、パイプの長さ調節を行うときには、パイプを枠体に取付けた状態でパイプの長さの見当を付けてからパイプを取外して切断し、また、切断したパイプを取付けるという面倒な作業を行うことがなくなる。
【００５１】
また、パイプ３９の外周面に複数の凹部４２を形成したので、壁の厚さの異なる壁体に対応するためのパイプ長さの切断作業を容易に行うことができる。
【００５２】
【発明の効果】
以上の実施の形態から明らかなように本発明によれば、室内側と室外側にそれぞれ開口を設け、内部に２個の送風ファンを設けた枠体を備え、前記枠体を壁体内に納めて設置する換気装置において、前記枠体は、前記壁体の室内側壁面に設けられ、その左右両端部に円弧形状を有する補強枠を設けない壁穴に挿入設置され、前記枠体の左右端部は、前記壁穴の左右両端部に形成された円弧形状に沿うように挿入設置される形状を有したので、室内側壁面の壁穴の左右端部が円弧形状であるため、壁体内に、特に壁穴の角部を補強する補強枠を設けないで、室内側壁面に取付施工ができるとともに、従来の矩形の壁穴形状より壁体内の断熱材を切り取る面積をより少なくし、壁体内の非断熱面積をより小さくできる断熱性の高い換気装置を提供することができる。
【００５３】
また、室内側に室内側排気口および室内側給気口と、室外側に室外側排気口および室外側給気口とを設けた枠体の内部に、前記室外側給気口と前記室内側給気口を給気用ファンを介して連通させる給気流路と、前記室内側排気口と前記室外側排気口を排気用ファンを介して連通させる排気流路とを形成し、前記給気流路と前記排気流路が交差する部分に熱交換素子を配設したので、熱交換素子を有する換気装置が取り付けられる熱交換換気の必要な断熱性の高い建物において、壁体内の断熱材の切り欠き面積を抑え、熱エネルギーロスを小さくした換気装置を提供できる。
【００５４】
また、枠体の左右端部形状を、壁穴の左右端部の円弧形状に沿うように前記壁穴に挿入設置される円弧状としたので、換気装置を室内側壁面に設置時に、壁穴と枠体の隙間を小さくでき、枠体端部に形成される取付用フランジと室内側壁面の接触面積を確保するために、前記取付用フランジを外方に向けて大きくしなくても、壁体内の結露の原因となる室内空気の壁体内への侵入を防止できるとともに、室内側に露出する取付フランジをより小さくでき、コンパクトで美観に優れた換気装置を提供することができる。
【００５５】
また、枠体内の左右端部に、内部に送風ファンおよび電動機を備えた送風機ユニットを設けたので、送風機ユニットの外郭が、枠体の左右端部の内側面に近接することになり、枠体の内部の左右のデッドスペースがなくなり、枠体の幅寸法を小さくできるとともに、建物の非断熱面積をより小さくできる。
【００５６】
また、枠体の左右端部が送風機ユニットの外枠の約半分を形成するように前記送風機ユニットを設けたので、枠体の左右端部が送風機ユニットの外枠の約半分を兼ねることになり、枠体の内部の上下、左右のデッドスペースがなくなるため、より枠体の寸法を小さくできるとともに、建物の非断熱面積をさらに小さくできる。
【００５７】
また、枠体内の左右両端部のそれぞれに送風ファンを配設したので、壁体内に埋め込むことのできる枠体の高さに制限のある建物において、枠体の高さを大きくせずに、風量を増加でき、換気能力の高い換気装置を提供できる。
【００５８】
また、枠体の室内側端面の外周部に外方に向けて突出する取付用フランジを設け、前記取付用フランジに、室内側から操作することにより、室内側壁面を形成する室内側パネルを前記取付用フランジとで狭持する支持片を備え、前記枠体を前記室内側パネルに固定する固定手段を設けたので、着脱自在で、壁体を傷めることなく、アンカーナットなどの固定部品を設けなくてよい、施工が容易な換気装置を提供できる。
【００５９】
また、枠体の室内側開口と室外側開口のそれぞれに開閉自在なシャッターを設けたので、室内側のシャッター、および室外側のシャッターの閉鎖により、枠体内部に封印された空気が、断熱材の働きをして換気装置の停止時でも壁体の断熱を維持することができる。
【００６０】
また、枠体の室外側開口に室外と連通するパイプを一体に形成したので、枠体の室外側開口の外周面と、パイプとの結合部のシールをする必要がなく、確実な気密性が確保できるとともに、パイプの長さ調節を行うときには、パイプを枠体に取付けた状態でパイプの長さの見当を付けてからパイプを取外して切断し、また、切断したパイプを取付けるという面倒な作業を行うことがなくなる。
【００６１】
また、パイプの外周面に複数の凹部を形成したので、壁の厚さの異なる壁体に対応するためのパイプ長さの切断作業を容易に行うことができる。
