【０００１】
【発明の属する技術分野】
本発明は、送風方向を調節するため、向きが変化される風向板を有する風向調節部材を、送風口へ容易に脱着可能にした送風装置に関する。
【０００２】
【従来の技術】
従来、空気調和機の室内機等の送風装置には、送風口内の風向調節部材に風向板を設けると共にモータ等の駆動源で風向板を回動して送風方向を調節するものが多い。送風装置は、使用に伴い送風口内部、風向調節部材等が汚れるが、これらの箇所の清掃は、一般に風向板の存在で清掃具等を送風口内へ挿入するのが困難となるため、汚れを完全に除去できず、また、清掃自体に手間を要した。一方、風向板を有する風向調節部材を送風口と別体で脱着可能にすれば、清掃やメンテナンス等が容易になると想定できるが、風向板の駆動のため、風向調節部材には駆動源、駆動機構、電気配線等が必要となり、脱着可能な構造を実現するのは容易ではなかった。
【０００３】
このような状況の中、図１１（ａ）（ｂ）に示す実開昭５９−１３１９９９号公報で風向調節部材を脱着可能にした送風装置１が提示されている。送風装置１は、モータ３及び偏心カム４を本体２に設け、送風装置１の本体２の送風口と別体の風向調節部材５には、複数の垂直な風向板６を、接触子８を突設した連結部材７で連結して左右に回動自在に設けている。風向調節部材５の本体２への装着で、接触子８が偏心カム４に接触し、モータ３の駆動で偏心カム４を回転させ、風向板６が回動している。風向調節部材５にはモータ３が存在しないため、清掃時に、風向調節部材５を送風装置１より取り外して水洗い可能にすると共に、本体２の送風箇所内部の清掃も容易にしている。
【０００４】
【発明が解決しようとする課題】
昨今の送風装置は、送風方向を左右に調節するだけでなく、上下に調節可能にしたものも多い。このような送風装置は、垂直方向の風向板に加えて水平方向の風向板を上下に回動自在に設けると共に、各風向板を駆動する複数のモータを設けているので、上述した送風装置１の構造をそのまま適用した場合、駆動機構等が非常に複雑となり、風向調節部材の送風口への脱着が困難になると共に、コストが大幅に上昇する問題がある。
【０００５】
また、昨今の送風装置は、要求される送風量が増大していることから、装置全体が大型化する傾向がある。よって、上述した送風装置１の構造を大型の送風装置へそのまま適用した場合、風向調節部材等の剛性が不足して風向板の適正な回動が妨げられるおそれがあると共に、風向調節部材自体を送風口へ正確に位置決めして装着するのが困難となる問題がある。
【０００６】
本発明は、斯かる問題に鑑みてなされたものであり、モータの駆動力を風向板へ歯車を介して伝達することで、風向調節部材及び送風口等の被装着箇所の構造を簡易な構造にした送風装置を提供することを目的とする。
また、水平方向および垂直方向の複数の風向板を風向調節部材に設けても、送風口への脱着容易性を妨げない送風装置を提供することを目的としている。
さらに、送風装置が大型化した場合でも、所要の剛性及び送風口への確実な装着性を確保した送風装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明に係る送風装置は、風向板が向きの変化可能に回動自在に取り付けてある風向調節部材が、送風口に脱着自在に装着され、前記風向板の向きを変化させるモータを有している送風装置において、前記モータは、モータ軸に設けた駆動歯車を備え、前記風向板は、回動中心となる回転軸と、該回転軸に設けた被動歯車とを備え、前記風向調節部材は送風口に懸架された状態から前上方へ回動することにより前記被動歯車に前記駆動歯車が噛合し、前記風向調節部材が前記送風口に脱着自在に装着する構成としてあることを特徴とする。
【０００８】
本発明においては、送風口周囲に設けたモータと、脱着式の風向調節部材に設けた風向板とを歯車で駆動連結するので、駆動伝達機構が簡易化され、風向調節部材を送風口へ容易に装着できる。また、風向調節部材には電気的な部品、配線等が皆無となり風向調節部材自体の清掃性も向上する上、送風口内部の清掃も容易化できる。さらに、風向板の被動歯車は自由に回転するので、送風口に風向調節部材を装着する際、被動歯車が駆動歯車の状態に合致するように適宜回転して両歯車が噛合し、風向板を確実に駆動できる。また、風向調節部材を回転することで、自然に風向調節部材の送風口に対する上下方向の位置決めがなされ、装着時に風向調節部材を送風口の正規の位置に合わせる手間も大幅に低減できる。
【０００９】
本発明に係る送風装置は、前記風向調節部材は角枠形状であり、一枠辺部に設けたフックと、該一枠辺部と対向する他枠辺部に設けた長孔とを備え、係止突起を有する係止片が、前記長孔に摺動自在に取り付けてあり、前記送風口は開口が略矩形状であり、一辺側に設けた水平方向の係止軸と、該一辺側と対向する他辺側の内面に設けた係止孔とを備え、前記送風口の一辺側の係止軸に前記フックを係止することで懸架された状態の前記風向調節部材が、前記係止軸を回転中心に前記送風口の他辺側へ前上方へ回転した状態にされることにより、前記係止突起が前記係止孔に挿入されていると共に、前記風向調節部材が前記送風口へ前記係止片の摺動により係止装着されていることを特徴とする。
【００１０】
本発明においては、送風口の一辺側に係止軸を、風向調節部材の一枠辺部にフックを夫々設けることで、風向調節部材を送風口へ装着する際、一旦、前記フックを前記係止軸に係止すれば、風向調節部材が懸架された状態となり、装着作業の間、風向調節部材を支持し続ける状態から解放され、装着作業に要する負担を軽減できる。また、フックを係止軸へ外嵌係止した状態から、風向調節部材の他枠辺部が送風口の他辺側へ一致するように風向調節部材を回転することで、自然に風向調節部材の送風口に対する上下方向の位置決めがなされ、装着時に風向調節部材を送風口の正規の位置に合わせる手間も大幅に低減できる。
【００１１】
さらに、送風口の他辺側の内面には係止孔を設けると共に、風向調節部材は他枠辺部に設けた長孔に係止片を取り付けているので、上記回転で、係止片の係止突起が係止孔に挿入され、この状態より係止片を摺動するだけで係止突起を係止孔に係止でき、風向調節部材をワンタッチで確実に装着できる。また、装着された風向調節部材の取り外しは、係止片の係止を解除するだけで、風向調節部材の他枠辺部は送風口の他辺側から解放され、後は、一枠辺部のフックを係止軸から外すのみで、風向調節部材が送風口から切り離され、取り外しも容易に行える。なお、上記取り外しの際も、被動歯車が自由に回転するので、噛合状態の被動歯車と駆動歯車がスムーズに離反し、被動歯車と駆動歯車の噛合が取り外しを妨げることはない。
【００１６】
さらに、また、本発明に係る送風装置は、前記送風口には、前記一辺側と他辺側を繋ぐ補強板が設けてあり、該補強板には係止部が形成されている一方、前記風向調節部材には、前記一枠辺部と他枠辺部を繋ぐ枠補強板が設けてあり、該枠補強板には被係止部が形成されており、前記風向調節部材の前記送風口への装着状態で、前記被係止部に前記係止部が係止されていることを特徴とする。
【００１７】
本発明においては、送風口に補強板を、風向調節部材に枠補強板を夫々設けているので、送風装置が大型化しても、送風口、風向調節部材の両者に所要の剛性を確保できる。さらに、補強板には係止部、枠補強板には被係止部を夫々設けているので、風向調節部材の送風口への装着時に、前記係止部を前記被係止部に係止するだけで、風向調節部材の左右方向の位置決めも確保でき、風向調節部材が大型化しても容易に正規の位置に装着でき、風向板の駆動に必要な各歯車の噛合を規定通りの位置関係で確保できる。
【００１８】
【発明の実施の形態】
以下に、本発明をその実施形態を示す図面に基づき説明する。
図１は、本発明に係る送風装置１０の側面方向からの断面図である。送風装置１０は、上部１０ａの前上面パネル１１、前面１０ｂのオープンパネル１２、キャビネット１３等で筐体となる本体１５を形成している。本体１５は、内部上方に熱交換器１６、内部中央に送風手段としてクロスフローファン１４を設けると共に、下方には内部から外方へ連通して開口する送風口１７を形成している。送風口１７には、本体１５と別体の風向調節部材である角枠形状の枠部材２２を装着している。枠部材２２は、風向板として第１水平風向板１９、第２水平風向板２０、垂直風向板２１等を設けて、送風方向を上下左右に調節可能にしている。
【００１９】
図２、図３（ａ）に示すように送風口１７は、送風装置１０の幅方向を長手方向とした略矩形状であり、上方側の開口縁から口内奥へドレンパン１８を取り付けている。また、送風口１７は、一辺側となる下端１７ａの近傍に水平方向の係止軸１７ｃを設け、他辺側となる上端１７ｂの内面となるドレンパン１８の外方先端部１８ａに長穴形状の係止孔１８ｂを穿設している。なお、本実施形態では、送風口１７は長手方向となる幅方向が縦方向に比べてかなり長いため、長さが１５ｍｍの係止軸１７ｃを長手方向に間隔をへだてて計４箇所に設けると共に、係止孔１８ｂは長手方向に間隔をへだてて計３箇所に設けている。
【００２０】
送風装置１０における送風口１７の右端１７ｄの周囲近傍には、モータとして第１平行モータ３０と第２平行モータ３１を、第１モータ軸３０ａ及び第２モータ軸３１ａが水平となる姿勢で設けている。第１モータ軸３０ａには駆動歯車として円筒形歯車の第１上下駆動歯車３２を、第２モータ軸３１ａにも円筒形歯車の第２上下駆動歯車３３を夫々固着している。なお、本実施形態の第１上下駆動歯車３２及び第２上下駆動歯車３３は平歯車であり、モジュールが０．７５、歯数が１３、基準ピッチ円直径が９．７５ｍｍ、基準圧力角が２０度のものを使用している。
【００２１】
さらに、送風装置１０は、送風口１７の右端１７ｄ側となる下端１７ａの奥側にモータとして直交モータ３４を設けており、モータ軸３４ａには、駆動歯車として円錐形歯車の左右駆動歯車３５を固着している。本実施形態の左右駆動歯車３５は、斜交すぐばかさ歯車であり、歯形はグリーソン式、モジュールは０．８、基準圧力角は２０度、軸角は１３１度、歯数は１２、基準ピッチ円直径が９．６ｍｍのものを使用している。なお、第１平行モータ３０、第２平行モータ３１、直交モータ３４にはステッピングモータを用いて回転方向の制御を容易にしている。
【００２２】
また、送風口１７には、剛性を確保してドレンパン１８とキャビネット１３との間隔を所要寸法に維持するため、上端１７ｂ側のドレンパン１８と下端１７ａ側のキャビネット１３を繋ぐ補強板としてリブ２７を設けており、本実施形態では長手方向に間隔をあけて２箇所にリブ２７を設置している。これらリブ２７は、図３（ｂ）に示すように、前面２７ａに係止部として凹部２７ｂを凹設している。
【００２３】
一方、図４に示す枠部材２２は送風口１７の周囲に装着する外形寸法を有し、図５（ａ）（ｂ）にも示すように、一枠辺部である下辺部２２ａは板形状であり、他枠辺部である上辺部２２ｂは断面が屈折した板形状にしている。また、図６（ａ）に示すように、右側の端部付近には、上辺部２２ｂと下辺部２２ａを繋ぐ連結部２２ｃを設け、連結部２２ｃより右外方には、図６（ｂ）に示すカバー部２２ｄを形成している。なお、左側の端部付近は、右側とほぼ対称に連結部とカバー部を形成している。
【００２４】
図６（ａ）に示すように、枠部材２２は、送風口１７への装着状態で、係止孔１８ｂと対向する上辺部２２ｂの３箇所に長孔２２ｅを夫々穿設している。各長孔２２ｅは、係止孔１８ｂと略同等の長さ寸法を有し、幅は係止孔１８ｂより狭い寸法に設定している。各長孔２２ｅには、図７（ａ）（ｂ）にも示すように、係止片２９を摺動可能に取り付けている。係止片２９は、板状の鍔部２９ａの上面より逆Ｌ字形状の係止突起２９ｂを突設すると共に、係止突起２９ｂの幅方向の両側には爪部２９ｃを立設して長孔２２ｅへの取付け状態で長孔２２ｅの周端に係止し、係止片２９の摺動を確保しながら長孔２２ｅからの脱落を防止している。なお、鍔部２９ａは下面には把持部２９ｄを突設し、係止片２９の摺動を容易にしている。
【００２５】
また、図５（ａ）に示すように、枠部材２２の下辺部２２ａは、前端側に一部を開口した円弧状のフック２２ｆを形成している。さらに、下辺部２２ａは、上面から補助垂直風向板３６を取り付ける多数の垂直軸部２２ｇを、長手方向に所要の間隔をへだてて下辺部２２ａに対して垂直に突設している。また、最右側の垂直軸部２２ｇから右側に所要の間隔をへだてた箇所には、垂直風向板２１を取り付ける支持孔２２ｈを設けている。
【００２６】
さらに、枠部材２２は、長手方向の剛性を確保するため、上辺部２２ｂと下辺部２２ａを繋ぐ枠補強板として枠リブ２６を長手方向に間隔をあけて２箇所に設けている。枠リブ２６は、図５（ｂ）、図６（ａ）に示すように、上辺部２２ｂと下辺部２２ａを繋ぐベース部２６ａより第１突出部２６ｂ及び第２突出部２６ｃを突設しており、第１突出部２６ｂ及び第２突出部２６ｃの夫々の先端には、軸受孔２６ｄ、２６ｅを設けている。また、ベース部２６ａの後面２６ｆには、被係止部として凸部２６ｇを突設している。
【００２７】
なお、枠部材２２は、図４及び図６（ｂ）に示すように、右側の連結部２２ｃとカバー部２２ｄとの連結箇所となる右壁部２２ｉに右軸受孔２２ｊ、２２ｋを軸受孔２６ｄ、２６ｅと同心で設けると共に、図５（ａ）に示すように、左壁部２２ｍには左水平軸２２ｐ、２２ｑを軸受孔２６ｄ、２６ｅと同心で設けている。
【００２８】
枠部材２２へ取り付ける第１水平風向板１９と第２水平風向板２０は略同形状であり、以下、第１水平風向板１９で代表して説明する（なお、第１水平風向板１９の各部の符号は、第２水平風向板２０の対応する各部と同等の符号を付している）。
【００２９】
図８に示すように、第１水平風向板１９は、所要の長さ寸法を有する横長の板部材で形成され、一面１９ａより計４箇所のホルダー部１９ｂを、枠部材２２の左壁部２２ｍ、２箇所の枠リブ２６、右壁部２２ｉに夫々対応する箇所で立設している。最左側のホルダー部１９ｂには、軸孔１９ｃを設け、左から２番目のホルダー部１９ｂには第１回転軸１９ｄを左側へ水平に突設し、左から３番目のホルダー部１９ｂには第２回転軸１９ｅを右側へ水平に突設し、最右側のホルダー部１９ｂには、水平方向の回転軸として水平軸１９ｆを右側に突設している。
【００３０】
第１水平風向板１９は、最左側の軸孔１９ｃに枠部材２２の左壁部２２ｍの左水平軸２２ｐを挿入し、以下、第１回転軸１９ｄを左から２番目の軸受孔２６ｄに、第２回転軸１９ｅを左から３番目の軸受孔２６ｄに、最右側の水平軸１９ｆを右軸受孔２２ｊに挿入し、枠部材２２に上下へ回動自在に取り付けている。第１水平風向板１９は長手寸法が長いが、上記のように計４箇所で支持することで、安定した回動を可能にしている。
【００３１】
なお、本実施形態では、第１水平風向板１９のスムーズな回動を確保するために、ＰＯＭ（ポリアセタール）樹脂成形品の軸受けを上記各軸と各孔間に介在させている。このように第１水平風向板１９を取り付けた後、水平軸１９ｆには、被動歯車として第１平行モータ３０の第１上下駆動歯車３２と同型でＰＯＭ樹脂成形品の第１上下回動歯車３７を固着している。また、第２水平風向板２０も、第１水平風向板１９と同様に枠部材２２に上下へ回動自在に取り付け、水平軸２０ｆに、第２上下駆動歯車３３と同型でＰＯＭ樹脂成形品の第２上下回動歯車３８を固着している。
【００３２】
一方、図５（ｂ）に示すように、垂直方向の垂直風向板２１は、枠部材２２の上辺部２２ｂと下辺部２２ａ間の約３分の２の高さを有する板部材で形成され、下辺２１ａからは垂直方向の回転軸として垂直軸２１ｂを突設すると共に、下辺後端は切り欠いて取付軸２１ｃを突設している。また、図５（ａ）に示す補助垂直風向板３６は、垂直風向板２１と略同等の形状であり、切り欠いた下辺後端には取付軸３６ｃを突設しており、相異する点として下辺３６ａに垂直孔３６ｂを穿設している。
【００３３】
垂直風向板２１は、垂直軸２１ｂを枠部材２２の支持孔２２ｈに挿入し、下辺部２２ａに対して直交とした状態で左右に回転自在に取り付け、各補助垂直風向板３６の垂直孔３６ｂに枠部材２２の垂直軸部２２ｇを挿入し、夫々左右に回転自在に取り付けられている。このように取り付けた状態で、図９に示すように、垂直風向板２１の取付軸２１ｃ及び各補助垂直風向板３６の取付軸３６ｃを、細長形状の連結部材２３に穿設した各孔２３ａへ挿入し、垂直風向板２１と各補助垂直風向板３６を連結部材２３で連結し、垂直風向板２１と各補助垂直風向板３６が連動して回動するようにしている。
【００３４】
具体的には、垂直風向板２１を右方向（図中、黒矢印方向）へ回動すれば、連結部材２３が左方向（図中、黒矢印方向）へ直線移動し、この移動により各補助垂直風向板３６は右方向へ回動する。また、垂直風向板２１を左方向（図中、白矢印方向）へ回動すれば、連結部材２３は、右方向（図中、白矢印方向）へ直線移動し、各補助垂直風向板３６は、左方向（図中、白矢印方向）へ回動する。なお、連結部材２３は、所要箇所を屈折させて移動時に他の部材等と干渉するの防止している。
【００３５】
さらに、垂直風向板２１の垂直軸２１ｂには、被動歯車として円錐形歯車の左右回動歯車２４を固着している。本実施形態の左右回動歯車２４は、斜交すぐばかさ歯車であり、歯形はグリーソン式、モジュールは０．８、基準圧力角は２０度、軸角は１３１度、歯数は１６、基準ピッチ円直径が１２．８ｍｍのものを使用している。
【００３６】
上記のように第１水平風向板１９、第２水平風向板２０、垂直風向板２１、および補助垂直風向板３６を取り付けた枠部材２２を、送風口１７へ装着するには、図１０（ａ）（ｂ）に示すように、先ず、枠部材２２の下辺部２２ａのフック２２ｆを送風口１７の係止軸１７ｃに外嵌係止している。この係止で、枠部材２２が係止軸１７ｃに懸架された状態となり、装着の際、枠部材２２を支持し続ける負担を軽減している。次に、上記係止状態から枠部材２２を係止軸１７ｃを中心に前上方へ回転することで、枠部材２２の上辺部２２ｂと、送風口１７の上端１７ｂが一致した状態になっている。
【００３７】
上記一致で、枠部材２２は、送風口１７に対して上下方向に位置決め規制されている。また、上記回動時には、図３（ｂ）に示すように、送風口１７のリブ２７の凹部２７ｂに、枠部材２２の枠リブ２６の凸部２６ｇを係合させて、枠部材２２を送風口１７に対して左右方向にも正確に位置決めしている。この上下左右の位置決めにより長孔２２ｅの位置が送風口１７の係止孔１８ｂに自然と合致して、長孔２２ｅに取り付けた係止片２９の係止突起２９ｂが、送風口１７の係止孔１８ｂに挿入されている（図３（ａ）、図６（ａ）、図７参照）。
【００３８】
この状態で、図７（ｂ）に示すように、係止片２９を係止孔１８ｂ及び長孔２２ｅの長手方向に摺動させ、係止突起２９ｂを係止孔１８ｂの周縁に係止し、枠部材２２の上辺部２２ｂを送風口１７の上端１７ｂに係止し、装着を完了している。また、上記装着は上下左右に正確に位置決めされているため、第１モータ軸３０ａと水平軸１９ｆの軸間距離が設計値通りの寸法で平行な位置関係になり、第１平行モータ３０の第１上下駆動歯車３２と第１水平風向板１９の第１上下回動歯車３７は適正な状態で噛合している。以下、同様に第２平行モータ３１の第２上下駆動歯車３３と第２水平風向板２０の第２上下回動歯車３８も適正に噛合し、直交モータ３４のモータ軸３４ａと垂直風向板２１の垂直軸２１ｂが直交状態で設計通りの位置関係となり、左右駆動歯車３５と左右回動歯車２４も適正に噛合している。
【００３９】
なお、第１上下回動歯車３７、第２上下回動歯車３８、及び、左右回動歯車２４は、噛合前であれば自由回転可能なので、上記各歯車同士を噛み合せる際、歯車の山同士が一致した状態になっても、即座に回転して歯車の山と谷が一致して所要の噛合を確保している。また、枠部材２２を送風口１７より取り外す際も、各歯車同士の噛合が容易に解除され、枠部材２２のスムーズな取り外しを妨げないようにしている。
【００４０】
このように枠部材２２を装着した送風装置１０は、クロスフローファン１４を駆動することで、外部より本体１５の内部に取り入れた気体を、熱交換器１６を通過させて、送風口１７より外方へ送風している。送風方向を上下に調節する場合は、第１平行モータ３０及び第２平行モータ３１を駆動して、第１水平風向板１９及び第２水平風向板２０を上下に回動している。また、送風方向を左右に調節する場合は、直交モータ３４を駆動して垂直風向板２１を左右に回動し、補助垂直風向板３６も左右に連動回動させている。
【００４１】
また、送風装置１０の送風箇所の清掃等を行う場合は、上述した装着の際と反対の手順で、係止片２９の係止を解除して、係止軸１７ｃを中心に枠部材２２を下方に回動させ、フック２２ｆを係止軸１７ｃより外すことで、枠部材２２を送風口１７から容易に取り外している。枠部材２２の存在しない送風口１７は、奥まで効率良く掃除可能となり、さらに取り外した枠部材２２には、モータ等の電気部品が取り付けられていないため、枠部材２２自体の清掃も容易に行える。
【００４２】
なお、送風装置１０は、上記形態に限定されるものではなく、例えば、水平風向板、補助垂直風向板の個数は、使用される状況等に応じて適宜増減してもよい。また、送風方向の調節が上下方向のみに限定される場合は、垂直風向板、補助垂直風向板を省略してもよく、左右方向のみ調節する場合は、水平風向板を省略してもよい。
【００４３】
【発明の効果】
以上詳述した如く本発明に係る送風装置においては、モータの駆動力を歯車により、別体の枠部材である風向調節部材に取り付けた風向板へ伝達して風向板を回動するので、風向調節部材と送風口との間の動力伝達機構を簡易な構造にでき、それに伴い風向調節部材の脱着も行い易くなり、送風箇所の清掃も容易に行える。
【００４４】
また、風向調節部材は、一枠辺部を送風口の一辺側の係止軸に係止すると共に、他枠辺部を他辺側に係止片を介して係止するので、上下方向に位置決め精度を良好にして容易且つ確実に装着できる。さらに、風向調節部材と送風口の上下位置が正確になることで、風向調節部材側の被動歯車とモータの駆動歯車の噛み合い精度も向上し、風向板の駆動も正確に行える。なお、風向調節部材を取り外す際も、係止片の係止を解除することで容易に行える。
【００４７】
さらに、また、本発明に係る送風装置は、送風口に係止部を形成した補強板を設けると共に、風向調節部材に被係止部を形成した枠補強板を設けることで、送風口、風向調節部材を大型化しても所要の剛性を確保できる。また、風向調節部材の装着時に係止部と被係止部を係止することで、風向調節部材の送風口に対する左右方向の位置決めも確実に確保でき、歯車の噛み合い精度も向上して、風向板も一段と正確に回動できる。

BACKGROUND OF THE INVENTION
The present invention relates to a blower device in which a wind direction adjusting member having a wind direction plate whose direction is changed in order to adjust a blowing direction can be easily attached to and detached from a blowing port.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, many blower devices such as indoor units of an air conditioner are provided with a wind direction plate on a wind direction adjusting member in a blower opening and adjust the blowing direction by rotating the wind direction plate with a driving source such as a motor. The air blower becomes dirty inside the air outlet and the wind direction adjusting member with use, but cleaning of these locations generally makes it difficult to insert a cleaning tool into the air outlet due to the presence of the air direction plate. It could not be removed completely, and it took time and effort to clean itself. On the other hand, if the wind direction adjusting member having the wind direction plate can be detached from the air blowing port separately, it can be assumed that cleaning, maintenance, etc. will be facilitated. A mechanism, electrical wiring, and the like are required, and it is not easy to realize a detachable structure.
[0003]
Under such circumstances, a blower 1 in which a wind direction adjusting member is detachable is proposed in Japanese Utility Model Laid-Open No. 59-131999 shown in FIGS. 11 (a) and 11 (b). The air blower 1 is provided with a motor 3 and an eccentric cam 4 in the main body 2, and a plurality of vertical air direction plates 6 and contacts 8 are provided on the air blowing direction adjusting member 5 separately from the air blowing port of the main body 2 of the air blower 1. It connects with the protruding connection member 7, and is provided so that rotation to right and left is possible. By attaching the wind direction adjusting member 5 to the main body 2, the contact 8 comes into contact with the eccentric cam 4, the eccentric cam 4 is rotated by driving the motor 3, and the wind direction plate 6 is rotated. Since the motor 3 is not present in the wind direction adjusting member 5, the air direction adjusting member 5 is removed from the blower device 1 during cleaning and can be washed with water, and the inside of the blowing portion of the main body 2 is easily cleaned.
[0004]
[Problems to be solved by the invention]
Many recent blowers not only adjust the blowing direction to the left and right, but also can be adjusted up and down. In such a blower device, in addition to the vertical wind direction plate, a horizontal wind direction plate is provided so as to be rotatable up and down, and a plurality of motors for driving each wind direction plate are provided. When the above structure is applied as it is, the drive mechanism and the like become very complicated, and it becomes difficult to attach and detach the wind direction adjusting member to the blower opening, and there is a problem that the cost is significantly increased.
[0005]
Moreover, since the required ventilation volume has increased in recent air blowers, the whole apparatus tends to be enlarged. Therefore, when the structure of the air blower 1 described above is applied as it is to a large air blower, the wind direction adjusting member or the like is insufficient in rigidity, and proper rotation of the wind direction plate may be hindered. There is a problem that it is difficult to accurately position and install the air blowing port.
[0006]
The present invention has been made in view of such a problem. By transmitting the driving force of the motor to the wind direction plate via a gear, the structure of the mounting location such as the wind direction adjusting member and the air outlet is simplified. An object is to provide a blower device.
It is another object of the present invention to provide a blower that does not hinder the ease of detachment from the blower opening even if a plurality of wind direction plates in the horizontal direction and the vertical direction are provided on the wind direction adjusting member.
Furthermore, it aims at providing the air blower which ensured required rigidity and the reliable mounting property to an air blower, even when an air blower enlarged.
[0007]
[Means for Solving the Problems]
The blower device according to the present invention includes a motor for changing a direction of the wind direction plate, in which a wind direction adjusting member on which the wind direction plate is rotatably attached so that the direction can be changed is detachably attached to the blower opening. The motor includes a drive gear provided on a motor shaft, the wind direction plate includes a rotation shaft serving as a rotation center and a driven gear provided on the rotation shaft, and the wind direction adjusting member is The drive gear is engaged with the driven gear by rotating forward and upward from the state suspended from the air outlet, and the wind direction adjusting member is detachably attached to the air outlet.
[0008]
In the present invention, the motor provided around the air outlet and the wind direction plate provided on the detachable air direction adjusting member are driven and connected by a gear, so that the drive transmission mechanism is simplified and the air direction adjusting member is easily connected to the air outlet. Can be attached to. In addition, since there are no electrical parts, wiring, etc. in the wind direction adjusting member, the cleaning property of the wind direction adjusting member itself is improved, and cleaning of the inside of the air blowing port can be facilitated. Further, since the driven gear of the wind direction plate rotates freely, when the wind direction adjusting member is attached to the air blowing port, the driven gear is appropriately rotated so as to match the state of the drive gear, and both gears are engaged, and the wind direction plate is Can be driven reliably. In addition, by rotating the air direction adjusting member, the air direction adjusting member is naturally positioned in the vertical direction with respect to the air blowing port, and the labor for adjusting the air direction adjusting member to the normal position of the air blowing port at the time of mounting can be greatly reduced.
[0009]
In the blower according to the present invention, the wind direction adjusting member has a rectangular frame shape, and includes a hook provided on one frame side and a long hole provided on the other frame side facing the one frame side, A locking piece having a locking projection is slidably attached to the elongated hole, the opening of the blower opening has a substantially rectangular shape, a horizontal locking shaft provided on one side, and the one side The wind direction adjusting member in a state of being suspended by engaging the hook with a locking shaft on one side of the air blowing port.

It is characterized in that it is fixedly mounted by sliding the locking piece.
[0010]
In the present invention, by providing a locking shaft on one side of the air blowing port and a hook on one side of the wind direction adjusting member, when the air direction adjusting member is attached to the air blowing port, the hook is temporarily engaged with the hook. If it is locked to the stop shaft, the wind direction adjusting member is suspended and released from the state in which the wind direction adjusting member is continuously supported during the mounting operation, so that the burden required for the mounting operation can be reduced. Further, the wind direction adjusting member is naturally rotated by rotating the wind direction adjusting member so that the other frame side portion of the wind direction adjusting member coincides with the other side of the air blowing port from the state in which the hook is fitted and locked to the locking shaft. Positioning in the vertical direction with respect to the air blowing port is made, and it is possible to greatly reduce the trouble of aligning the air direction adjusting member with the normal position of the air blowing port at the time of mounting.
[0011]
In addition, a locking hole is provided on the inner surface of the other side of the air blowing port, and the wind direction adjusting member has a locking piece attached to the long hole provided in the other frame side part. The locking projection is inserted into the locking hole, and the locking projection can be locked to the locking hole simply by sliding the locking piece from this state, and the wind direction adjusting member can be securely attached with one touch. In addition, the removal of the installed wind direction adjusting member only releases the locking of the locking piece, and the other frame side portion of the wind direction adjusting member is released from the other side of the air blowing port. By simply removing the hook from the locking shaft, the wind direction adjusting member is separated from the blower opening and can be easily removed. Even during the above removal, the driven gear rotates freely, so that the meshed driven gear and the driving gear are smoothly separated from each other, and the meshing of the driven gear and the driving gear does not hinder the removal.
[0016]
Furthermore, in the air blower according to the present invention, the air blowing port is provided with a reinforcing plate that connects the one side and the other side, and the reinforcing plate has a locking portion, The wind direction adjusting member is provided with a frame reinforcing plate that connects the one frame side portion and the other frame side portion, and the frame reinforcing plate is formed with a locked portion, and the air blowing port of the wind direction adjusting member In the mounted state, the locking portion is locked to the locked portion.
[0017]
In the present invention, since the reinforcing plate is provided at the air blowing port and the frame reinforcing plate is provided at the wind direction adjusting member, the required rigidity can be ensured for both the air blowing port and the air direction adjusting member even if the size of the air blowing device is increased. In addition, since the reinforcing plate is provided with a locking portion and the frame reinforcing plate is provided with a locked portion, the locking portion is locked to the locked portion when the wind direction adjusting member is attached to the air blowing port. By simply doing this, the positioning of the wind direction adjusting member can be secured in the left-right direction, and even if the wind direction adjusting member is enlarged, it can be easily installed in the proper position, and the meshing of each gear necessary for driving the wind direction plate is in the specified positional relationship Can be secured.

[0028]
The first horizontal wind direction plate 19 and the second horizontal wind direction plate 20 to be attached to the frame member 22 have substantially the same shape, and will be described below as a representative of the first horizontal wind direction plate 19 (in addition, each part of the first horizontal wind direction plate 19) Are assigned the same reference numerals as the corresponding parts of the second horizontal wind direction plate 20).
[0029]
As shown in FIG. 8, the first horizontal wind direction plate 19 is formed of a horizontally long plate member having a required length dimension, and a total of four holder portions 19b are connected to the left wall portion 22m of the frame member 22 from one surface 19a.

[0030]
The first horizontal wind direction plate 19 inserts the left horizontal shaft 22p of the left wall portion 22m of the frame member 22 into the leftmost shaft hole 19c. Hereinafter, the first rotation shaft 19d is inserted into the second bearing hole 26d from the left. The second rotary shaft 19e is inserted into the third bearing hole 26d from the left, and the rightmost horizontal shaft 19f is inserted into the right bearing hole 22j, and is attached to the frame member 22 so as to be rotatable up and down. Although the first horizontal wind direction plate 19 has a long longitudinal dimension, the first horizontal wind direction plate 19 is supported in a total of four places as described above, thereby enabling stable rotation.
[0031]
In the present embodiment, in order to ensure smooth rotation of the first horizontal wind direction plate 19, bearings of a POM (polyacetal) resin molded product are interposed between the shafts and the holes. After the first horizontal wind direction plate 19 is attached in this manner, the first vertical rotation gear 37 of the POM resin molded product is the same type as the first vertical drive gear 32 of the first parallel motor 30 as the driven gear on the horizontal shaft 19f. Is fixed. Similarly to the first horizontal wind direction plate 19, the second horizontal wind direction plate 20 is attached to the frame member 22 so as to be rotatable up and down. The second horizontal wind direction plate 20 has the same type as the second vertical drive gear 33 on the horizontal shaft 20f. The second vertical rotation gear 38 is fixed.
[0032]
On the other hand, as shown in FIG. 5B, the vertical vertical wind direction plate 21 is formed of a plate member having a height of about two-thirds between the upper side portion 22b and the lower side portion 22a of the frame member 22, A vertical shaft 21b is projected from the lower side 21a as a vertical rotation shaft, and a rear end of the lower side is notched to project a mounting shaft 21c. Further, the auxiliary vertical wind direction plate 36 shown in FIG. 5A has substantially the same shape as the vertical wind direction plate 21, and a mounting shaft 36 c is projected at the rear end of the cut-out lower side, which is different. As shown, a vertical hole 36b is formed in the lower side 36a.
[0033]
The vertical wind direction plate 21 has the vertical shaft 21b inserted into the support hole 22h of the frame member 22 and is attached to the vertical hole 36b of each auxiliary vertical wind direction plate 36 so as to be rotatable left and right in a state of being orthogonal to the lower side portion 22a. The vertical shaft portion 22g of the frame member 22 is inserted and attached to the left and right to be freely rotatable. In this state of attachment, as shown in FIG. 9, the attachment shaft 21c of the vertical wind direction plate 21 and the attachment shaft 36c of each auxiliary vertical wind direction plate 36 are inserted into each hole 23a formed in the elongated connecting member 23. The vertical wind direction plate 21 and each auxiliary vertical wind direction plate 36 are connected by the connecting member 23 so that the vertical wind direction plate 21 and each auxiliary vertical wind direction plate 36 rotate in conjunction with each other.
[0034]
Specifically, if the vertical wind direction plate 21 is rotated in the right direction (black arrow direction in the figure), the connecting member 23 is linearly moved in the left direction (black arrow direction in the figure), and each movement is supported by this movement. The vertical wind direction plate 36 rotates to the right. Further, if the vertical wind direction plate 21 is rotated in the left direction (the white arrow direction in the figure), the connecting member 23 moves linearly in the right direction (the white arrow direction in the figure), and each auxiliary vertical wind direction plate 36 is Rotate leftward (in the direction of the white arrow in the figure). The connecting member 23 refracts a required portion to prevent interference with other members during movement.
[0035]
Further, a conical gear left / right rotating gear 24 is fixed to the vertical shaft 21b of the vertical wind direction plate 21 as a driven gear. The left and right rotating gear 24 of this embodiment is an oblique straight bevel gear, the tooth profile is Gleason, the module is 0.8, the reference pressure angle is 20 degrees, the shaft angle is 131 degrees, the number of teeth is 16, and the reference A pitch circle diameter of 12.8 mm is used.
[0036]
In order to mount the frame member 22 to which the first horizontal wind direction plate 19, the second horizontal wind direction plate 20, the vertical wind direction plate 21 and the auxiliary vertical wind direction plate 36 as described above are attached to the air outlet 17, FIG. As shown in (b), first, the hook 22f of the lower side portion 22a of the frame member 22 is externally engaged and locked to the locking shaft 17c of the blower port 17. With this locking, the frame member 22 is suspended from the locking shaft 17c, and the burden of continuing to support the frame member 22 during mounting is reduced. Next, the upper side portion 22b of the frame member 22 and the upper end 17b of the blower port 17 are aligned with each other by rotating the frame member 22 forward and upward about the locking shaft 17c from the locked state. .
[0037]
With the above agreement, the frame member 22 is regulated in the vertical direction with respect to the air blowing port 17. Further, at the time of the rotation, as shown in FIG. 3B, the convex portion 26 g of the frame rib 26 of the frame member 22 is engaged with the concave portion 27 b of the rib 27 of the blower port 17 to blow the frame member 22. It is also accurately positioned with respect to the mouth 17 in the left-right direction. The position of the long hole 22e naturally matches the locking hole 18b of the air blowing port 17 by this vertical and horizontal positioning, and the locking protrusion 29b of the locking piece 29 attached to the long hole 22e It is inserted into the hole 18b (see FIG. 3 (a), FIG. 6 (a), and FIG. 7).
[0038]
In this state, as shown in FIG. 7B, the locking piece 29 is slid in the longitudinal direction of the locking hole 18b and the long hole 22e, and the locking projection 29b is locked to the periphery of the locking hole 18b. The upper side 22b of the frame member 22 is locked to the upper end 17b of the air blowing port 17, and the mounting is completed. In addition, since the mounting is accurately positioned vertically and horizontally, the distance between the first motor shaft 30a and the horizontal shaft 19f is parallel to the design value, and the first parallel motor 30 has a first positional relationship. The first vertical drive gear 32 and the first vertical rotation gear 37 of the first horizontal wind direction plate 19 mesh with each other in an appropriate state. Thereafter, similarly, the second vertical drive gear 33 of the second parallel motor 31 and the second vertical rotation gear 38 of the second horizontal wind direction plate 20 are also properly engaged, and the motor shaft 34a of the orthogonal motor 34 and the vertical wind direction plate 21 are The vertical shaft 21b is in an orthogonal state and has a positional relationship as designed, and the left and right drive gears 35 and the left and right rotation gears 24 are also properly meshed.
[0039]
The first vertical rotation gear 37, the second vertical rotation gear 38, and the left / right rotation gear 24 can be freely rotated before meshing. Even if they are in a state of coincidence, the gears rotate immediately and the crests and troughs of the gears coincide to ensure the required meshing. Further, when the frame member 22 is removed from the blower port 17, the meshing between the gears is easily released, so that the smooth removal of the frame member 22 is not hindered.
[0040]
The blower 10 with the frame member 22 thus mounted drives the cross flow fan 14 so that the gas taken into the main body 15 from the outside passes through the heat exchanger 16 and passes through the air outlet 17. It is blowing towards. When adjusting the blowing direction up and down, the first parallel motor 30 and the second parallel motor 31 are driven to rotate the first horizontal wind direction plate 19 and the second horizontal wind direction plate 20 up and down. Further, when adjusting the blowing direction to the left and right, the orthogonal motor 34 is driven to rotate the vertical wind direction plate 21 to the left and right, and the auxiliary vertical wind direction plate 36 is also rotated to the left and right.
[0041]
Moreover, when cleaning the ventilation location of the air blower 10, etc., the lock | rock of the latching piece 29 is cancelled | released in the procedure opposite to the time of the mounting | wearing mentioned above, and the frame member 22 is centered on the latching shaft 17c. The frame member 22 is easily removed from the air blowing port 17 by rotating downward and removing the hook 22f from the locking shaft 17c. The blower port 17 where the frame member 22 does not exist can be efficiently cleaned to the back. Further, since the electric component such as a motor is not attached to the removed frame member 22, the frame member 22 itself can be easily cleaned. .
[0042]
In addition, the air blower 10 is not limited to the said form, For example, you may increase / decrease suitably the number of a horizontal wind direction board and an auxiliary | assistant vertical wind direction board according to the condition etc. to be used. Further, when the adjustment of the air blowing direction is limited to only the vertical direction, the vertical wind direction plate and the auxiliary vertical wind direction plate may be omitted, and when only the horizontal direction is adjusted, the horizontal wind direction plate may be omitted.
[0043]
【The invention's effect】
As described above in detail, in the blower according to the present invention, the driving force of the motor is transmitted to the wind direction plate attached to the wind direction adjusting member, which is a separate frame member, by the gears, and the wind direction plate is rotated. The power transmission mechanism between the adjusting member and the air outlet can be made simple, and the air direction adjusting member can be easily attached and detached accordingly, and the air blowing part can be easily cleaned.
[0044]
In addition, the wind direction adjusting member locks one frame side to the locking shaft on one side of the air outlet, and locks the other frame side to the other side via a locking piece. It can be mounted easily and reliably with good positioning accuracy. Further, since the vertical positions of the wind direction adjusting member and the air outlet are accurate, the meshing accuracy between the driven gear on the wind direction adjusting member side and the drive gear of the motor is improved, and the wind direction plate can be driven accurately. In addition, when removing a wind direction adjustment member, it can carry out easily by cancelling | releasing the latching | locking piece.
[0047]
Furthermore, the air blower according to the present invention is provided with a reinforcing plate in which a locking portion is formed in the air blowing port and a frame reinforcing plate in which a locked portion is formed in the air direction adjusting member, so that the air blowing port and the wind direction are provided. Even if the adjusting member is enlarged, the required rigidity can be ensured. In addition, by locking the locking portion and the locked portion when the wind direction adjusting member is mounted, the positioning of the wind direction adjusting member in the left-right direction with respect to the air blowing port can be ensured reliably, the gear meshing accuracy is improved, and the wind direction is also improved. The plate can also be rotated more accurately.
