【発明の実施の形態】
請求項1に記載の発明は、壁部に設けた換気口に装着される筒状で、室内側に外方に向けて突出する方形のフレーム部を備えた本体と、この本体のフレーム部の外周に装着される枠状で、前面はパネルにより閉鎖され、左右の側面または上面には通気口を設けたグリルと、前記通気口に設けられるシャッターとを備え、前記シャッターは、グリルの外側に設けた操作部の操作により閉鎖時はグリルの枠面に沿うように前記通気口を閉鎖し、開放時にはグリルの枠面に対し略垂直状に可動し、前記通気口を開放する構成としたことにより、通気口の開口部の面積を大きくすることができるので圧損を下げて騒音を低減できるとともに、シャッターがグリルの枠面に対して略垂直状に可動するので通気口の開口部から吹き出される給気流を整流して騒音を低減することができるという作用を有する。
【0015】
請求項2記載の発明は、特に請求項1記載の換気装置について、シャッターを複数枚のシャッター板により構成したことにより、シャッターの開放時のシャッター板の突出量を小さくしてグリル内部の空間を大きくとることができ、例えばフィルターなどの内容物を収納する空間を確保できるという作用を有する。
【0016】
請求項3記載の発明は、特に請求項1記載の換気装置について、パネルの周端部およびグリルの枠状部より操作部が突出しないように通気口の設けられる左右の側面または上面を凹ませて形成したことにより、操作部が何かに接触する度合いが少なくなり、使用者等の意に反して操作部が誤動作することを防止できるという作用を有する。

【0019】
請求項6記載の発明は、特に請求項1、2または4記載の換気装置について、シャッターは、開放時には複数枚のシャッター板をグリルの外方側に向け開放する構成としたことにより、給気流の吹き出しを整流するとともに、グリル内部の空間を大きくとることができるので、換気装置の騒音を低減することができるという作用を有する。
【0020】
以下、本発明の実施の形態について図1〜図8を参照しながら説明する。
【0021】
(実施の形態1)
図1〜図4に示すように、壁部1に設けた換気口2に装着される筒状部3の室内側に外方に向け突出する方形のフレーム部4を設け、筒状部3内にファン5が位置するようにモータ6をフレーム部4に取り付けたファンモータ7を内蔵した本体8を設け、本体8のフレーム部4の外周に装着される枠状で前面はパネル9により閉鎖され、左右の側面10または上面11に通気口12を設けたグリル13を設け、通気口12に設けられるシャッター14を複数枚のシャッター板15により形成し、シャッター板15の両端の片側寄りに軸16を設け、通気口12の側部のグリル13の内面に設けた軸受部17に軸16を介してシャッター板15を回動自在に設け、グリル13の外側に移動自在に設けられる操作部であるレバー18とともに移動する駆動部19をグリル13の内面側に設け、駆動部19に連結された駆動体20をシャッター板15に係合するシャッター開閉機構21を設け、レバー18の操作によりシャッター14の閉鎖時にはグリル13の枠面にシャッター板15が沿うように可動して通気口12を閉鎖し、シャッター14の開放時にはグリル13の枠面に略垂直状にシャッター板15が可動し、通気口12を開放するように設け、パネル9の周端部9aおよびグリル12の枠状部13aよりレバー18が突出しないように通気口12の設けられる左右の側面10または上面11を凹ませて形成する。
【0022】
そして、フィルター部材22をジグザグ状に形成したフィルター23を環状に形成し、内面にスポンジ板24の貼付けたパネル9の内面に、グリル13側に突出するように設けられた取付部25にフィルター23を係合し、略方形状にグリル13内に配設した構成とする。
【0023】
上記構成において、給気を目的とする換気を行う場合には、レバー18を操作しシャッター開閉機構21を介して複数枚のシャッター板15をグリル13の枠面に略垂直状に可動し、通気口12を開放したのち、換気装置を運転すると、ファンモータ7が駆動し室外26の空気が本体8内に給気され、グリル13内に方形状に設けたフィルター23を通り、室外26の空気中に含まれる塵埃等が除去され、浄化された空気が開放されたシャッター板15により整流された状態で通気口12より室内27に放散されて給気される。
【0024】
そして、暴風雨や給気の必要のないときには、ファンモータ7の運転を停止し、レバー18を操作し、レバー18と連動する駆動部19の移動によりシャッター開閉機構21を介してシャッター板15がグリル13の枠面に沿うように通気口12を閉鎖し、室外26の空気が室内27に給気されないようにする。
【0025】
このように本発明の実施の形態1の換気装置によれば、壁部1に設けた換気口2に装着される筒状で、室内側に外方に向けて突出する方形のフレーム部4を設けた本体8と、この本体8のフレーム部4の外周に装着される枠状で前面はパネル9により閉鎖され、左右の側面10または上面11に通気口12を設けたグリル13と、通気口12に設けられるシャッター14とを備え、シャッター14はグリル13の外側に設けたレバー18の操作により、閉鎖時はグリル13の枠面に沿うように通気口12を閉鎖し、開放時にはグリル13の枠面に対し略垂直状に可動し、前記通気口12を開放する構成としたので、グリル13の側面10または、上面11に設けられる通気口12の開口部の面積を大きくすることができるため、圧損を下げられ騒音を低減できるとともに、通気口12には給気流の障害となるような格子がなく、シャッター14により給気流の整流することができ騒音を低減することができる。
【0026】
また、シャッター14を複数枚のシャッター板15により構成したので、シャッター板15が開放されたときの寸法が小さくでき、フィルター23を装着する空間を大きくとることができるため、低圧損なフィルター23を装着することが可能となり、騒音を低減することができる。
【0027】
また、パネル9の周端部9aおよびグリル13の枠状部13aよりレバー18が突出しないように通気口12の設けられる左右の側面10および上面11を凹ませて形成したので、製作時、梱包時、施工時等において、レバー18に接触する度合が少なくなり、レバー18が何かに接触し動いて誤動作することを防止することができる。
【0028】
なお、実施の形態1では、ファンモータ7を設けた強制給気の換気装置について説明したが、図5に示すように、ファンモータを設けていない自然給気の換気装置としても同様の作用効果をもたらすことはいうまでもない。
【0029】
(実施の形態2)
図6に示すように、グリル13Aの通気口12Aに設けたシャッター14Aの開放時に複数枚のシャッター板15Aを斜め前方に向け開放する構成とする。
【0030】
上記構成において、換気装置を運転すると、室外空気筒状部3内に給気され、グリル13Aに設けたシャッター板15Aの面に沿い通気口12Aから斜め前方に吹き出されることとなり、天井面や壁面に向かい送風されることがなくなる。
【0031】
このように本発明の実施の形態2の換気装置によれば、グリル13Aに設けた通気口12Aに設けられるシャッター14Aの開放時に、複数枚のシャッター板15Aを斜め前方に向け開放するので、給気流は通気口12Aから天井面や壁面に向け送風されることがなくなり、天井面や壁面の汚れるのを防止することができる。
【0032】
(実施の形態3)
図7に示すように、グリル13Bの通気口12Bに設けたシャッター14Bの開放時に複数枚のシャッター板15Bをグリル13Bの内方側に向け開放される構成とする。
【0033】
上記構成において、換気装置を運転すると給気流がグリル13Bの内側から通気口12Bを通り室内に放散される。このとき、シャッター板15Bをグリル13Bの内方側に開放していることにより、給気流はシャッター板15Bの面により整流される。
【0034】
このように本発明の実施の形態3の換気装置によれば、グリル13Bの通気口12Bに設けたシャッター14Bの開放時の複数枚のシャッター板15Bをグリル13Bの内方側に向け開放される構成としたので、シャッター板15Bにより給気流が整流され、騒音が低減できるとともに、外風を受けたときにシャッター板15Bは閉鎖方向に風圧を受けることとなり、外風に対する密閉性を高めることができる。
【0035】
(実施の形態4)
図8に示すように、グリル13Cの通気口12Cに設けたシャッター14Cの開放時に複数枚のシャッター板15Cをグリル13Cの外方側に向けて開放させる構成とする。
【0036】
上記構成において、換気装置を運転すると、給気流がグリル13Cの内側から通気口12Cを通り室内に放散される。このとき、シャッター板15Cはグリル13Cの外方側に向け開放していることにより、給気流はシャッター板15Cの面により整流される。
【0037】
このように本発明の実施の形態4の換気装置によれば、グリル13Cの通気口12Cに設けたシャッター14Cの開放時に複数枚のシャッター板15Cをグリル13Cの外方側に向け開放させる構成としたので、シャッター板15Cの面により給気流が整流されることとなるとともに、フィルター23を装着する空間を大きく形成することができ、低圧損のフィルター23を装着することができ、騒音を低減することができる。
【0038】
【発明の効果】
以上のように、本発明の換気装置によれば、壁部に設けた換気口に装着される筒状で、室内側に外方に向けて突出する方形のフレーム部を設けた本体と、この本体のフレーム部の外周に装着される枠状で、前面はパネルにより閉鎖され、左右の側面または上面には通気口を設けたグリルと、前記通気口に設けられるシャッターとを備え、前記シャッターは、グリルの外側に設けた操作部の操作により、閉鎖時はグリルの枠面に沿うように前記通気口を閉鎖し、開放時にはグリルの枠面に対し略垂直状に可動し、前記通気口を開放する構成としたので、騒音を低減できる換気装置を提供することができる。
