吹出しベーン２はエアコン室内機の本体１の正面に取り付けられ、閉じている状態では本体カバー１ａと同一面をなしている（図１（ａ）及び図２（ａ）を参照）。
熱交換器４は吸込み口３から吸込まれた室内の空気と図示せぬ室外機から送られた冷媒の間で熱交換を実施する。プロペラファン５は吸込み口３から室内の空気を吸込んで熱交換器４に通し、その熱交換器４を通過した空気を室内に送風する。
【０００８】
上端部支持部材６は先端６ａが吹出しベーン２の上端部にピン接合され、その吹出しベーン２を支持している。なお、上端部支持部材６の先端６ａは、吹出しベーン２の上端部に対して接合角度が自在に変わるように係合されており、上端部支持部材６の長手方向の下側には歯車６ｂが形成されている。
下端部支持部材７は先端７ａが吹出しベーン２の下端部にピン接合され、その吹出しベーン２を支持している。なお、下端部支持部材７の先端７ａは、吹出しベーン２の下端部に対して接合角度が自在に変わるように係合されており、下端部支持部材７の長手方向の上側には歯車７ｂが形成されている。
【０００９】
回転体であるモータ８の回転軸を上端部支持部材６の歯車６ｂと噛み合う歯車８ａの回転軸と連結し、モータ８により上端部支持部材６を駆動して、吹出しベーン２の上側を開閉する。なお、モータ８は上側開閉手段を構成している。

【００１０】
次に動作について説明する。
図１（ａ）及び図２（ａ）に示すように、吹出しベーン２が閉じている状態では、吹出しベーン２が本体カバー１ａと同一面をなしているが、モータ９が歯車９ａを右回転させると、その歯車９ａと下端部支持部材７の歯車７ｂが噛み合うことにより、下端部支持部材７が左方向に移動する。
これにより、図１（ｂ）及び図２（ｂ）に示すように、吹出しベーン２の上側が閉じたまま、吹出しベーン２の下側が開くようになる。

これにより、図１（ｃ）及び図２（ｃ）に示すように、吹出しベーン２の下側が閉じたまま、吹出しベーン２の上側が開くようになる。
なお、吹出しベーン２の上側が開いているとき、モータ８が歯車８ａを右回転させると、その歯車８ａと上端部支持部材６の歯車６ｂが噛み合うことにより、上端部支持部材６が右方向に移動して、図１（ａ）及び図２（ａ）のように吹出しベーン２が閉じた状態に戻る。
【００１２】
以上で明らかなように、この実施の形態１によれば、上端部支持部材６を駆動して、吹出しベーン２の上側を開閉するモータ８と、下端部支持部材７を駆動して、吹出しベーン２の下側を開閉するモータ９とを設けるように構成したので、例えば、温風であれば、吹出しベーン２の下側を開いて下方向に送風し、冷風であれば、吹出しベーン２の上側を開いて上方向に送風することができるようになり、その結果、冷風や温風を効率よく循環させることができる効果を奏する。

さらに、この実施の形態１によれば、モータ８が上端部支持部材６の歯車６ｂと噛み合う上側開閉手段を構成し、モータ９が下端部支持部材７の歯車７ｂと噛み合う下側開閉手段を構成しているので、複雑な機構を用いることなく、吹出しベーン２の開閉機構を構築することができる効果を奏する。
【００１４】
実施の形態２．
図３はこの発明の実施の形態２によるエアコン室内機を示す断面図であり、図において、図２と同一符号は同一または相当部分を示すので説明を省略する。
上端部支持部材１１は先端１１ａが吹出しベーン２の上端部に対して上下方向に移動自在に係合されており（図４を参照）、上端部支持部材１１は先端１１ａが伸縮するピストン機構を備えている。

【００１５】
クランク機構１３は上端部支持部材１１の先端１１ａを伸縮させることにより、吹出しベーン２の上側を開閉する上側開閉手段を構成している。
クランク機構１４は下端部支持部材１２の先端１２ａを伸縮させることにより、吹出しベーン２の下側を開閉する下側開閉手段を構成している。
図５はクランク機構１３（または１４）の構成を示す斜視図であり、クランク機構１３（または１４）はモータ２１と、モータ２１の回転軸に取り付けられているギア２２と、ギア２２と噛み合って回転軸２４を回転させることにより、上端部支持部材１１の先端１１ａ（または下端部支持部材１２の先端１２ａ）を伸縮させるギア２３とから構成されている。
【００１６】
次に動作について説明する。
図１（ａ）及び図３（ａ）に示すように、吹出しベーン２が閉じている状態では、吹出しベーン２が本体カバー１ａと同一面をなしているが、クランク機構１４が回転軸２４を回転させると、下端部支持部材１２の先端１２ａが左方向に伸びる。
これにより、図１（ｂ）及び図３（ｂ）に示すように、吹出しベーン２の上側が閉じたまま、吹出しベーン２の下側が開くようになる。
なお、吹出しベーン２の下側が開いているとき、クランク機構１４が回転軸２４を反転させると、下端部支持部材１２の先端１２ａが縮むので、図１（ａ）及び図３（ａ）のように吹出しベーン２が閉じた状態に戻る。
【００１７】
一方、吹出しベーン２が閉じている状態のとき、クランク機構１３が回転軸２４を回転させると、上端部支持部材１１の先端１１ａが左方向に伸びる。
これにより、図１（ｃ）及び図３（ｃ）に示すように、吹出しベーン２の下側が閉じたまま、吹出しベーン２の上側が開くようになる。
なお、吹出しベーン２の上側が開いているとき、クランク機構１３が回転軸２４を反転させると、上端部支持部材１１の先端１１ａが縮むので、図１（ａ）及び図３（ａ）のように吹出しベーン２が閉じた状態に戻る。
【００１８】
これにより、上記実施の形態１と同様に、例えば、温風であれば、吹出しベーン２の下側を開いて下方向に送風し、冷風であれば、吹出しベーン２の上側を開いて上方向に送風することができるようになり、その結果、冷風や温風を効率よく循環させることができる効果を奏する。
なお、この実施の形態２によれば、クランク機構１３が上端部支持部材１１の先端１１ａを伸縮させる上側開閉手段を構成し、クランク機構１４が下端部支持部材１２の先端１２ａを伸縮させる下側開閉手段を構成しているので、複雑な機構を用いることなく、吹出しベーン２の開閉機構を構築することができる効果を奏する。
【００１９】
また、吹出しベーン２の開閉手段として、上端部支持部材１１及び下端部支持部材１２の代わりに、吹出しベーン２の開放側に張力をもつバネなどの弾性部材を用いてもよい。
この場合、例えば、バネの一端を吹出しベーン２に取り付け、他端を固定された支持部材に取り付ける。また、室内機の本体１の内部にモータと、このモータの回転軸に取り付けたプーリとを設けるとともに、そのバネの一端にワイヤロープや紐状のもの（以下、ロープという）の一端に取り付け、このロープを上記バネの内部及び上記支持部材に設けられた穴を通した上で、このロープの他端を上記プーリに巻き付ける。
【００２０】
上記のように構成した上で、モータを回転させると、その回転がプーリに伝わり、上記ロープを上記プーリに巻き込むことによりロープが室内機に引き込まれ、これにより、バネが圧縮するとともに吹出しベーン２が閉じる。
モータを逆方向に回転すると、プーリに巻き付けられていたロープの張力が緩むので、圧縮されていたバネの延伸力でロープが外側に引き出されるとともに吹出しベーン２が開く。
この場合も、上記実施の形態１，２と同様の効果を奏することができる。
【００２１】
【発明の効果】
以上のように、この発明によれば、上端部支持部材を駆動して、吹出しベーンの上側を開閉する上側開閉手段と、下端部支持部材を駆動して、吹出しベーンの下側を開閉する下側開閉手段とを設けるように構成したので、例えば、温風であれば、吹出しベーンの下側を開いて下方向に送風し、冷風であれば、吹出しベーンの上側を開いて上方向に送風することができるようになり、その結果、冷風や温風を効率よく循環させることができる効果がある。
