【発明の属する技術分野】
本発明は、換気口に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
一般に換気口は、図６に図示したように壁面21に設けた取付孔22（一般的にはダクト）に嵌入される筒部23と、該筒部23に連設されて壁外面に露出する換気部24とで構成されるものであり、該換気部24は風雨の侵入を防いだり、また、外観を良好にするための通気窓板25と、該通気窓板25の略全周を囲繞する状態で連設されるカバー筒体26とで構成されている。
【０００３】
従来の通気窓板25は、例えば特許第２９０５９６２号公報に開示されているように、図７に図示したような該通気窓板25に折り曲げ片29付き桟板部27を残して孔28を形成し、この折り曲げ片29を起こして通気窓部30を並設したものである。
【０００４】
ところで、この従来の通気窓板25としては、図８に図示したように上向きに所定角度で折曲した前記折り曲げ片29が連設される左右方向の通気窓部30 を上下方向に複数並設し、排風を下方へ誘導する設定とした下方誘導型や、図９に図示したように左方部位は右向きに、右方部位は左向きに所定角度で折曲した前記折り曲げ片29が連設される上下方向の通気窓部30を左右方向に複数並設し、排風を左右に分流する設定とした左右分流型等が提案されている。
【０００５】
しかし、前記下方誘導型においては、換気口の下方を通行する通行人に排風が当たることがあり、前記左右分流型においても、排風が天井へも誘導され、天井を汚してしまうという問題があった。
【０００６】
そこで最近、図１０に図示したように通気窓板25の上方を前記下方誘導型に設定し、その余を前記左右分流型に設定することで、排風を左右に分流しつつ全体としては緩やかに下方向に誘導して天井及び通行人の双方へ排風が当たらない構成とした三方分流型の通気窓板25が提案されている。
【０００７】
ところが、この三方分流型の通気窓板25においても、換気口の左右方向に位置する壁が該換気口から近い位置にある場合、左右方向への排風により、該壁を汚してしまう問題がある。
【０００８】
本発明は、上述の問題点を解決したもので、天井，壁及び通行人に排風が当たらない極めて実用性に秀れた換気口を提供するものである。

【００１８】
【発明の実施の形態】
図１〜５，１１〜１３は本発明の一実施例を図示したものであり、以下に説明する。
【００１９】
本実施例は、壁面１に設けられる筒部２と該筒部２の屋外側に設けられる換気部３とから成る換気口であって、前記換気部３は通気窓部４が並設された通気窓板５と該通気窓板５を囲繞する状態で連設されるカバー筒体６とで構成され、壁面１から突出する該カバー筒体６の先端周縁を含む開口面Ｓは壁面１に対して傾斜する傾斜面に構成されているものである。
【００２０】
各部を具体的に説明すると、筒部２は壁面１に形成された略円形状の取付孔８（実際には、壁面１に穿設された取付孔８に配設されたダクト。このダクトは図示省略。）と嵌合する円筒形状のものが採用されている。
【００２１】
換気部３は、通気窓板５と該通気窓板５の全周を囲繞する状態で連設されるカバー筒体６とより成り、この換気部３は前記筒部２に被嵌される構成である。尚、通気窓板５はカバー筒体６に対して回動自在に取り付けられている。
【００２２】
カバー筒体６は、筒部２に対して回動自在に取り付けられている。
【００２３】
また、カバー筒体６は、開口面Ｓを平坦面（平面視が直線となる面）とし、カバー筒体６の壁面１から突出する側（図１〜３中左側）において、該カバー筒体６の側部６ａの中程に前記筒部２の側部２ａの延長線Ｌ上に位置する構成である。
【００２４】
通気窓部４は、複数の長窓を並設したものが採用されている。また、この通気窓部４は、前記通気窓板５を打ち抜きプレス，絞りプレス加工，打ち抜きプレス加工により皿状に形成した後、この通気窓板５を排風制御片７付き桟板部９を残してプレス加工により打ち抜くことで形成される（図７の従来の方法と同様）。
【００２５】
この通気窓部４は、通気窓板５の上方部位においては左右方向に延設されて上下方向に複数並設され、その余の部位においては上下方向に延設されて左右方向に複数並設されている。
【００２６】
排風制御片７は、排風制御片７付き桟板部９を残して通気窓部４を形成した後、前記通気窓板５に対して裏方向へ所定角度折曲することで形成されている。
【００２７】
この排風制御片７は等幅で、通気窓板５の上方部位においては上向きに図４に図示したように前記桟板部９に対して所定角度α折曲されて排風を下方へ誘導するように構成され、その余の部位の左方部位においては右向きに図３に図示したように前記桟板部９に対して所定角度β折曲されて排風を左方へ誘導するように構成され、右方部位においては左向きに図３に図示したように前記桟板部９に対して所定角度β折曲されて排風を右方へ誘導するように構成されている。
【００２８】
尚、本実施例においては、前記カバー筒体６を前記通気窓板５の全周を囲繞する状態で該通気窓板５と連設するように構成したが、一部を囲繞するものでも良い。
【００２９】
また、本実施例においては、カバー筒体６として、該カバー筒体６の壁面１から突出する側において、該カバー筒体６の側部６ａの中程に前記筒部２の側部２ａの延長線Ｌ上に位置する構成を採用したが、延長線Ｌ上に側部６ａが位置しない構成を採用しても良い。
【００３０】
図中符号10は、取付孔８に筒部２を係止するための係止板である。
【００３１】
本実施例は上述のように構成したから、壁面１から突出するカバー筒体６の前記開口面Ｓは、壁面１に対して傾斜する傾斜面に構成されているから、例えば前記開口面Ｓを右方向が突出する傾斜面とした場合、筒部２を通って通気窓部４から排出される排風の内、カバー筒体６の突出する右方向から排出される排風は、カバー筒体６の側面６ａと当接することで該側面６ａにガイドされて排出方向が可及的にカバー筒体６の前方に誘導され、筒部２を通って通気窓部４の排風がカバー筒体６の右側に位置する壁に当接することが阻止される。
【００３２】
また、従来は、例えば図５に図示したようにマンションの廊下等に換気口を取り付ける場合、図１１に図示したような取り付け場所Ａにおいては壁面Ｘが汚れやすいため、例えば図１２のような左方誘導型を、また、取り付け場所Ｂにおいては壁面Ｙが汚れやすいため、例えば図１３のような右方誘導型を準備しなければならず、従って、排風制御片７の向きが異なる２タイプの換気口を準備しなければならない。更に、取り付け場所Ｃにおいては上記のような問題はなく、よって、例えば図９のような左右分流型を準備しなければならない。尚、近くに天井がある場合、天井を汚したくないという要求は常に存在する。この点、本実施例によれば前記カバー筒体６を回動して突出方向を変えるだけで容易に右方向若しくは左方向への排風を阻止する設定とすることができるから、本実施例一種を準備するだけで全ての取り付け部位への対応が可能となる。
【００３３】
また、カバー筒体６を回動自在に設けない場合でも、取り付け場所Ｃにおいては左右どちら側の壁も汚す心配がないから、前記カバー筒体６の前記開口面Ｓを右方向が突出する傾斜面とした通気窓板５と、左方向が突出する傾斜面とした通気窓板５との二つのタイプで右方向，左方向若しくは上方向への排風の阻止に対応できる。
【００３４】
以上、本実施例は、例えば換気口の右方向にして該換気口から近い位置に壁があっても、前記開口面Ｓを右方向が突出する傾斜面に設定することで、排風は該壁に当たらず、よって、該壁が排風によって汚れることを確実に阻止できる極めて実用性に秀れた換気口となる。
