Description

【０００１】
【発明の属する技術分野】
本発明は、屋外と連通するダクトの接続される接続部材の装着部に本体を装着して天井に設置する換気装置に関する。
【０００２】
【従来の技術】
近年、屋外と連通するダクトが接続されるダクト接続口と、本体に設けた通風口に対応し、本体の側面が装着される装着部を設けた接続部材を介して本体を天井に設置し、ダクトを介して室内の汚染空気を室外に排出する換気装置が普及している。
【０００３】
従来、この種の一例として図１４〜図１９に示されるものが知られている。以下、その構成について図１４〜図１９を参照しながら説明する。
【０００４】
図１４および図１５の第１の例に示すように、下面に吸込口１０１を有し、複数の側面に通風口１０２を設け内部に送風機１０３が設けられた換気装置の本体１０４と、本体１０４の通風口１０２が設けられた側面が装着される装着部１０５を有し、通風口１０２に連通する本体側接続口１０６およびダクト１０７と連通するダクト側接続口１０８を一体的に設け、内部にシャッター１０９を設けた接続部材１１０とを設け、天井１１１に取り付けた本体１０４の吸込口１０１側にはグリル１１２を設けていた。
【０００５】
また、図１６および図１７の第２の例に示すように複数設けられる通風口のうち、不使用な通風口１０２Ａがある場合には、装着部１０５Ａに遮へい板１１３を設けた遮へい部材１１４で遮へいしていた。
【０００６】
また、図１８および図１９の第３の例に示すように、本体１０４Ａの通風口１０２Ｂを設けた側面が係合する接続部材１１０Ａの装着部１０５Ｂには、本体１０４Ａが装着されたときに本体１０４Ａに設けた通風口１０２Ｂの４周が囲まれるようにクッション材１１５を設けていた。
【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、ダクト１０７の接続された接続部材１１０を天井１１１に設けた開口１１６の縁部に取り付け、本体１０４を開口１１６より天井裏内に挿入し、本体１０４の側面を接続部材１１０の装着部１０５に装着していたが、本体１０４の側面と接続部材１１０の装着部１０５間に隙間が発生し易く、風漏れを生じるとともに、接続部材１１０の装着部１０５に本体１０４の側面を合致させるための案内が無かったので取り付け工事に手間がかかるという課題があり、風漏れがなく取付工事の省施工化が図れることが要求されている。
【０００８】
また、遮へい板１１３を設けた遮へい部材１１４を取り付けた場合にも風漏れおよび取り付け工事に手間がかかるという課題があり、風漏れが無く取付工事の省施工化が図れることが要求されている。
【０００９】
また、接続部材１１０Ａの装着部１０５Ｂに通風口１０２Ｂを囲むようにクッション材１１５を設けた場合には、本体１０４Ａが装着部１０５Ｂの下方から上方に向かい摺動して装着されるときに、クッション材１１５により滑りが悪く、装着性が悪いとともに、クッション材１１５の損傷も大きく風漏れを生じるという課題があり、装着性が良く、風漏れをなくすことが要求されている。
【００１０】
本発明は、上記課題を解決するもので、風漏れがなく、取付工事の省施工化を図ることができる換気装置を提供することを目的とする。
【００１１】
【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、下面に吸込口を有し側面に通風口を設けた換気扇の本体と、この本体の前記通風口の設けられた側面が装着される装着部を有し、前記通風口に連通する本体側接続口およびダクトと連接するダクト側接続口を一体に設け、内部に開閉自在なシャッターを設けた接続部材とを備え、前記接続部材の装着部の断面略コの字状のレールを縦方向に設け、前記本体の通風口の縦方向の縁部に段部を設けて、前記本体の通風口を設けた側面に前記レールに係合する係合部を形成し、前記接続部材に前記本体を接続する構成とした換気装置。
【００１２】
この本発明によれば、風漏れがなく、取付工事の省施工化を図ることができる換気装置を提供することができる。
【００１３】
【発明の実施の形態】
本発明の請求項１に記載の発明は、下面に吸込口を有し、側面に通風口を設けた換気装置の本体と、この本体の前記通風口の設けられた側面が装着される装着部を有し、前記通風口に連通する本体側接続口およびダクトと連通するダクト側接続口を一体的に設け、内部に開閉自在なシャッターを設けた接続部材とを備え、前記接続部材の装着部に断面略コの字状のレールを縦方向に設け、前記本体の通風口の縦方向の縁部に段部を設けて、前記本体の通風口を設けた側面に前記レールに係合する係合部を形成し、前記接続部材に前記本体を接続する構成としたものであり、本体を接続部材に装着時には接続部材に設けたレールに、本体に設けた係合部を係合して本体を接続部材に接続することとなり、接続時の取付工事が容易にでき省施工化を図ることができるという作用を有する。
【００１４】
以下、本発明の実施の形態について図１〜図１３を参照しながら説明する。
【００１５】
（実施の形態１）
図１〜図４に示すように、下面に吸込口１を有し、側面に通風口２を設け、内部に送風機３を収納した箱状の換気装置の本体４と、本体４の通風口２の設けられる側面５が装着される装着部６を有し、通風口２に連通する本体側接続口７およびダクト８と連通するダクト側接続口９を一体的に設け、内部に開閉自在なシャッター１０を設けた接続部材１１とを備え、接続部材１１の装着部６に外側に向け開口した断面略コの字状のレール１２を縦方向に設け、本体４の通風口２の縦方向の縁部１３に段部１４を設けレール１２に係合する係合部１５を通風口２を設けた側面５に形成し、本体４の吹出口１６側は吹出ダクト１７と接続される形状で内部に外風防止用シャッター１８を設け、本体４が装着できる装着部６を設けたアダプター１９に装着され、天井２０に設けた開口２１を覆うようにグリル２２を設け構成する。
【００１６】
上記構成において、換気装置を取り付け施工するときには、天井２０に設けた開口２１の一方側に縁部に吹出ダクト１７の接続されたアダプター１９を設け他方の縁部には、他の室と連通されたダクト８を接続部材１１に接続して設け、本体４の吹出口１６がアダプター１９側となるように本体４を開口２１より天井裏内に挿入する。
【００１７】
このとき、接続部材１１に設けたレール１２に本体４の通風口２を形成した側面５に設けた係合部１５が係合し、レール１２により案内されながら本体４が天井裏内に挿入され、本体４の吹出口１６側はアダプター１９に、本体４の通風口２側は接続部材１１に装着され、本体４は開口２１の縁部に取り付けられ本体４の吸込口１の下方にはグリル２２を取り付け施工が完了する。
【００１８】
そして、換気装置を運転すると、送風機３が駆動し、吸込口１から自室の空気が吸い込まれるとともに、ダクト８を介して他室の空気がシャッター１０を開放しながら接続部材１１を通じて本体４内に吸い込まれ、吹出口１６よりアダプター１７に送られ外風防止用シャッター１８を開放し、吹出ダクト１７を介して室外に排出されることとなる。
【００１９】
また、換気装置の運転停止時には、送風機３の運転が停止され、シャッター１０および外風防止用シャッター１８が閉鎖され、吹出ダクト１７を介して室外より侵入しようとする外風は、外風防止用シャッター１８を閉鎖勝手方向に押圧することにより外風の侵入が防止されるとともに、接続部材１１内に設けたシャッター１０により自室の汚染された空気や温度差の異なる空気が他室に侵入するのが防止できることとなる。
【００２０】
このように本発明の実施の形態１の換気装置によれば、下面に吸込口１を有し、側面５に通風口２を設け内部に送風機３を収納した換気装置の本体４と、本体４の通風口２の設けられた側面５が装着される装着部６を有し、通風口２に連通する本体側接続口７およびダクト８と連通するダクト側接続口９を一体的に設け内部に開閉自在なシャッター１０を設けた接続部材１１とを備え、接続部材１１の装着部６に外側に向け開口した断面略コの字状のレール１２を縦方向に設け、本体４の通風口２を設けた側面５にレール１２に係合する係合部１５を形成し、接続部材１１に本体４を接続する構成としたので、本体４を接続部材１１に接続するとき、接続部材１１に設けたレール１２に本体４に設けた係合部１５が係合し、レール１２より案内されて接続部材１１に本体４が密接状態で取り付けられることとなり、風漏れが防止されるとともに、本体４の取付施工が容易となり、取付工事の省施工化が図れる。
【００２１】
なお、実施の形態１では通風口２を１個用いて説明したが本体４の３側面のいずれかにも通風口２を設けても良いことはいうまでもない。
【００２２】
（実施の形態２）
図５〜図７に示すように、通風口２Ａを設けた本体４Ａの側面５Ａがレール１２Ａを介して装着される装着部６Ａを有し、通風口２Ａとの連通を遮へいするように遮へい板２３を設けた遮へい部材２４を形成し不使用の通風口２Ａを遮へいする構成とする。
【００２３】
上記構成において、複数の通風口２Ａのうち、通風を必要としない通風口２Ａがある場合には、本体４Ａに設けた係合部（図示せず）に遮へい部材２４に設けたレール１２Ａを係合し、本体４Ａに遮へい部材２４を取り付け、通風口２Ａを遮へい状態で天井２０に設けたアダプタ１９に本体４Ａを装着し、本体４Ａを開口２１の縁部に取り付ける。
【００２４】
そして、換気装置が運転されると吸込口１より自室の空気が吸い込まれ、アダプター１９を介して室外に排出され、他室の換気は行われず自室の換気のみが行われることとなる。
【００２５】
このとき、３個設けられる通風口２Ａのうち１個のみ不使用の場合には他の２個の通風口２Ａは他室と連通し、自室および他室の換気が行われることとなる。
【００２６】
このように本発明の実施の形態２の換気装置によれば、通風口２Ａを設けた本体４Ａの側面５Ａがレール１２Ａを介して装着される装着部６Ａを有し、通風口２Ａとの連通を遮へいするように遮へい板２３を設けた遮へい部材２４を形成し、不使用の通風口２Ａを遮へいする構成としたので、本体４Ａと遮へい部材２４間からの風漏れを防止することができる。
【００２７】
（実施の形態３）
図８および図９に示すように、断面が略コの字状に形成されるレール１２Ｂの溝幅２５を本体に設けた係合部（図示せず）が係合する入口側となる下方側を大きく、上方に向かうにしたがい順次狭くなるように接続部材１１Ａまたは遮へい部材２４Ａを形成した構成とする。
【００２８】
上記構成において、接続部材１１Ａまたは遮へい部材２４Ａに、本体を接続するときには、本体に設けた係合部をレール１２Ｂの溝幅２５の広い部分に係合したのち、順次上昇させると、係合部はレール１２Ｂの溝幅２５の狭い部分に移動し、接続部材１１Ａまたは遮へい部材２４Ａの装着部６Ｂに装着され、本体は接続部材１１Ａまたは遮へい部材２４Ａに密接状態で接続されることとなる。
【００２９】
このように本発明の実施の形態３の換気装置によれば、略コの字状に形成されるレール１２Ｂの溝幅２５を、本体に設けた係合部が係合する入口側となる下方側を大きく、上方に向かうにしたがい順次狭くなるように接続部材１１Ａまたは、遮へい部材２４Ａを形成したので、本体が接続部材１１Ａまたは遮へい部材２４Ａに接続する略コの字状のレール１２Ｂの入口側となる下方側の溝幅２５が広いことにより、本体の係合部との係合が容易で、取り付け作業が容易となるとともに、接合部材１１Ａまたは、遮へい部材２４Ａに本体が溝幅２５の上部の狭い部により密接して接続されることで、風漏れの防止も行うことができる。
【００３０】
（実施の形態４）
図１０および図１１に示すように、通風口２Ｂを設けた本体４Ｂの側面５Ｂと接続部材１１Ｂの装着部６Ｃ間に対応する通風口２Ｂの側方に縦方向に凸部２６を設け、接続部材１１Ｂ側に凸部２６の係合する縦方向の凹部２７と、本体側接続口７の上部と下部に横方向のクッション材等よりなるクッション手段２８を設け、凸部２６と凹部２７により係合手段２９を形成した構成とする。
【００３１】
上記構成において、接続部材１１Ｂに本体４Ｂを接続するときには、接続部材１１Ｂの装着部６Ｃに設けた凹部２７に本体４Ｂに設けた凸部２６を合わせ、本体４Ｂを上方に向け移動させることにより、接続部材１１Ｂの装着部６Ｃに本体４Ｂが接続され、本体４Ｂに設けられた通風口２Ｂの左右側方は凸部２６と凹部２７による係合手段２９により通風抵抗が増大し遮へいされて密閉され、通風口２Ｂの上下はクッション手段２８により密閉されることとなる。
【００３２】
このように本発明の実施の形態４の換気装置によれば、通風口２Ｂを設けた本体４Ｂの側面５Ｂと接続部材１１Ｂの装着部６Ｃ間に通風口２Ｂの側方を遮へいする凹部２７と凸部２６が係合する係合手段２９を縦方向に設け、通風口２Ｂの上部と下部を遮へいするクッション材等よりなるクッション手段２８を設けたので、通風口２Ｂの側方はクッション材を設けなくても係合手段２９により通気抵抗が増大して通風が遮へいされ風漏れを防止することができる。
【００３３】
（実施の形態５）
図１２および図１３に示すように、係合手段の凸部２６Ａと凹部２７Ａを鋭角的に係合するように、凸部２６Ａの先端を先細り状または鋭角状に形成し、凹部２７Ａを先細り状または鋭角状の溝により形成した構成とする。
【００３４】
上記構成において、接続部材１１Ｃの装着部６Ｄに設けられる凹部２７Ａは先のとがった先細り状または鋭角状の溝により形成され、本体４Ｃの通風口２Ｃの側方に設けられる凸部２６Ａは先端が先細り状または鋭角状にとがった突起により形成されることにより、接続部材１１Ｃに本体４Ｃを接続するときに、接続部材１１Ｃに設けた凹部２７Ａに対し、本体４Ｃに設けた凸部２６Ａの係合がスムースに行え、密接状態で接続されることとなる。
【００３５】
このように本発明の実施の形態５の換気装置によれば、係合手段の凸部２６Ａと凹部２７Ａを鋭角的に係合するように凸部２６Ａの先端を先細り状または鋭角状にし、凹部２７Ａを先細り状または鋭角状の溝により形成したので、凸部２６Ａと凹部２７Ａよりなる係合手段の係合が容易となるとともに、溶接状態が良くなり、風漏れの防止効果がさらに向上する。
【００３６】
【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、下面に吸込口を有し、側面に通風口を設けた換気装置の本体と、この本体の前記通風口の設けられる側面が装着される装着部を有し、前記通風口に連通する本体側接続口およびダクトと連通するダクト側接続口を一体的に設け、内部に開閉自在なシャッターを設けた接続部材とを備え、前記接続部材の装着部に断面略コの字状のレールを縦方向に設け、前記本体の通風口の縦方向の縁部に段部を設けて、前記本体の通風口を設けた側面に前記レールに係合する係合部を形成し、前記接続部材に、前記本体を接続する構成としたので、本体と接続部材間からの風漏れを防止することができるとともに、換気装置の設置時における接続部材への本体の取付け工事の省施工化が図れる換気装置を提供できる。
【００３７】
また、通風口を設けた本体の側面がレールを介して装着される装着部を有し、前記通風口との連通を遮へいするように遮へい板を設けた遮へい部材を形成し、不使用の通風口を遮へいする構成としたので、本体と遮へい部材間からの風漏れを防止できる。
【００３８】
また、コの字状に形成されるレールの溝幅を本体に設けた係合部が係合する下方側を大きく、上方に向かうにしたがい順次狭くなるように接続部材または、遮へい部材を形成したので、換気装置の設置工事時において、本体と接続部材または、遮へい部材との係合性が向上し、作業が容易になるので、作業性の向上と風漏れ防止の両立を図ることができる。
【００３９】
また、通風口を設けた本体の側面と接続部材の装着部間に通風口の側方を遮へいする凹部と凸部が係合する係合手段を縦方向に設け、前記通風口の上部と下部を遮へいするようにクッション手段を設けたので、係合手段により、通気抵抗を増加させて本体と接続部材間からの風漏れを防止できる。
【００４０】
また、係合手段の凸部の先端および凹部の底部を先細り状に形成して係合させたので、凸部と凹部の係合性が向上し、風漏れを防止できる。
