Description

【０００１】
【発明の属する技術分野】
本発明は、集合住宅や戸建住宅などで用いられて好適な給気口に関する。
【０００２】
【従来の技術】
従来、室内外を連通するように壁に通気通路を貫通させ、この通気通路が室内に臨む開口部分を空気吹き出し口とした給気口が提供されている。この種の給気口は、室内外での気圧差を利用して外気を室内に取り入れるようにしている。すなわち、室内において換気設備などを用いると、外気圧に比べて室内の気圧が低下するので、その際の室内外の気圧差により外気を室内に取り入れるようにしたものである。
そして、この種の給気口では、その構造上、外気温度の空気がそのまま室内に流れ込む。
【０００３】
【発明が解決しようとする課題】
一方、冬期では、室内外(屋内外)温度差が２０°Ｃを越えることもある。
このような場合、給気口から冷たい外気が室内にそのまま流れ込んだのでは、居住者に寒いという不快感が与えられる。
そのため、給気口が閉じられてしまうことが多く、給気口が閉じられると、室内に供給されるべきである新鮮な外気の量が減り、換気不足を生じ、結露やカビ、化学物質過敏症の発生の原因となる。
本発明は前記事情に鑑み案出されたものであって、本発明の目的は、居住者に不快感を与えることなく外気を室内に取り入れることができ、これにより給気口が閉じられてしまうことで生じる換気不足を解消できる給気口を提供することにある。
【０００４】
【課題を解決するための手段】
前記目的を達成するため本発明は、室内外を連通する給気通路および空気吹き出し口を介して外気を室内に吹き出させる給気口であって、第１空気通路と第２空気通路と空気混合路とを備え、前記第１空気通路と第２空気通路は互いに仕切られ、前記第１空気通路の上流端は前記給気通路に連通可能に設けられ、前記第２空気通路の上流端は前記室内に連通可能に設けられ、前記空気混合路は、前記第１空気通路の下流端と第２空気通路の下流端とのそれぞれに接続され、第１空気通路を流れる空気により第２空気通路に気流を生じさせると共に第１空気通路を流れる空気と第２空気通路を流れる空気を混合させるように構成され、前記空気混合路の下流端により前記空気吹き出し口が構成され、室内の壁に設けられた前記給気通路の開口よりも大きな直径で形成され、前記開口に臨ませかつ前記給気通路の延在方向とほぼ直交する方向に延在し前記壁に対して離間接近する方向に移動可能に配置された円板状の内側ガイド部材と、前記内側ガイド部材が前記開口に臨む面と反対の面に臨ませて前記内側部材とほぼ同軸上に配置される環板状の外側ガイド部材とを備え、前記第１空気通路は、前記開口の周囲に位置する前記室内の壁部分と前記内側ガイド部材との間で構成され、前記第２空気通路は、内側ガイド部材と外側ガイド部材との間で構成され、前記空気混合路は、前記内側ガイド部材の端部の外側に露出する前記室内の壁部分と外側ガイド部材との間で構成され、回転することで前記内側ガイド部材を前記壁に対して離間接近する方向に移動させ前記第１空気通路の断面積および前記第２空気通路の断面積を変えると共に、前記内側ガイド部材を前記壁に当接し前記第１空気通路を閉塞する第１空気通路閉塞状態と、前記内側ガイド部材を前記外側ガイド部材に当接し前記第２空気通路を閉塞する第２空気通路閉塞状態とを形成する雄ねじ部材が前記内側ガイド部材の雌ねじに螺合し前記外側ガイド部材を貫通して設けられていることを特徴とする。
【０００５】
本発明によれば、給気口内において外気と室内空気が混合されたのち室内に吹き出され、室内温度に近づけられた外気が室内に吹き出されることになる。
【０００６】
【発明の実施の形態】
以下、本発明の給気口を添付図面にしたがって説明する。
まず、第１の実施の形態から説明すると、図１は第１の実施の形態に係る給気口の断面側面図、図２は同正面図、図３は内側ガイド部材の正面図、図４(Ａ)、(Ｂ)は外側ガイド部材の取り付け説明図を示す。
図１において符号１２は室内、符号１４は室内外を仕切る壁、符号１６は給気口を示し、前記壁１４を貫通して給気通路１８が設けられ、符号１８０２は給気通路１８の室内側の開口を示している。なお、給気通路１８の室外側の開口あるいは給気通路１８の途中に、虫の侵入を阻止するための防虫網などが配設されている。外気は前記給気通路１８を経て給気口１６の空気吹き出し口２０から室内に吹き出され、符号１９は、給気通路１８が室内１２に開口する部分に取着されたスリーブを示す。
前記給気口１６は、第１空気通路２２、第２空気通路２４、空気混合路２５とを備えており、これら第１、第２空気通路２２、２４、空気混合路２５は本実施の形態では壁１４と内側ガイド部材２６と外側ガイド部材２８を介して形成されている。
【０００７】
前記内側ガイド部材２６は、図１および図３に示すように、給気通路１８よりも大きな直径の円板状に形成され、その肉厚は、中央部が厚く、外周部が薄く形成されている。
前記内側ガイド部材２６の一方の面２６Ａは、その中央部が内側ガイド部材２６の厚さ方向に凸状に形成され、他方の面２６Ｂは、その中央部が内側ガイド部材２６の厚さ方向に凹状に形成されている。
前記内側ガイド部材２６の外周部には雌ねじ３０が貫通形成され、内側ガイド部材２６の外周部の周方向に間隔をおいた箇所に４つのピン挿通孔３２が貫通形成されている。
【０００８】
前記外側ガイド部材２８は均一の厚さで環板状に形成され、その外径は内側ガイド部材２６の外径よりも大きな寸法で形成され、その中央には給気通路１８の直径よりも小さいものの室内空気を吸い込むのに十分な直径の中心孔２８０２が形成されている。なお、外側ガイド部材２８の厚さや断面形状は図１に示される平板に限らず任意である。外側ガイド部材２８には、図４(Ｂ)に示すように、雄ねじ部材取り付け孔３４が貫通形成され、図４(Ａ)に示すように、外側ガイド部材２８の周方向に間隔をおいた箇所に４つのピン取り付け孔３６が貫通形成されている。これら雄ねじ部材取り付け孔３４と４つのピン取り付け孔３６は、内側ガイド部材２６と外側ガイド部材２８を同一軸心上に合わせた時に内側ガイド部材２６の雌ねじ３０と４つのピン挿通孔３２に合致する箇所に形成されている。なお、内側ガイド部材２６と外側ガイド部材２８は、木材や合成樹脂、金属などの材料を用いて形成することができるが、結露し易い状況に置かれることを考えた場合、断熱性のよい木材や合成樹脂のような材料が好ましい。
【０００９】
前記内側ガイド部材２６と外側ガイド部材２８は、４本のピン３８と、１本の雄ねじ部材４０を介して配設されている。
すなわち、４本のピン３８が、給気通路１８の開口１８０２の周囲の壁１４に立設され、これらピン３８はそれぞれ内側ガイド部材２６のピン挿通孔３２に移動可能に挿通され、図４(Ａ)に示すように、各ピン３８の小径雄ねじ部３８０２が外側ガイド部材２８のピン取り付け孔３６に挿通され、この小径雄ねじ部３８０２に外側ガイド部材２８の外側からナット４２が螺合される。
【００１０】
また、前記雄ねじ部材４０は、図４(Ｂ)に示すように、雄ねじ部４００２と雄ねじ部４００２の頭部をなすつまみ部４００４とを備え、つまみ部４００４が外側ガイド部材２８の外側に位置するように雄ねじ部４００２が外側ガイド部材２８の雄ねじ部材取り付け孔３４に空転可能に挿通される。
そして、前記雄ねじ部材４０には、雄ねじ部４００２からつまみ部４００４にわたりピン挿通孔４００６が貫通形成されており、壁１４に立設されたピン４４がピン挿通孔４００６に挿通され、これにより雄ねじ部材４０はその長手方向に移動不能でかつ回転可能に配設されている。
また、前記雄ねじ部材４０の雄ねじ部４００２は内側ガイド部材２６の雌ねじ３０に螺合され、したがって、つまみ部４００４を回転操作すれば、内側ガイド部材２６は４本のピン３８に案内されつつ壁１４に対して離間接近する方向に移動することになる。
【００１１】
このように４本のピン３８と、１本の雄ねじ部材４０を介して、内側ガイド部材２６と外側ガイド部材２８は給気通路１８と同一軸心上に配設され、また、内側ガイド部材２６は凸状の面２６Ａが給気通路１８に臨み、かつ、給気通路１８の軸心に対して直交する方向に広がるように配設され、外側ガイド部材２８も給気通路１８の軸心に対して直交する方向に広がるように配設されることになる。そして、前記第１空気通路２２は、壁１４と内側ガイド部材２６との間の環板状の空間により形成され、第２空気通路２４は、内側ガイド部材２６と外側ガイド部材２８との間の環板状の空間により形成され、空気混合路２５は、内側ガイド部材２６の半径方向外方で壁１４と外側ガイド部材２８との間の環板状の空間により形成されている。また、前記第１空気通路２２の軸心および第２空気通路２４の軸心ならびに空気混合路２５の軸心は互いにほぼ平行しており、また、給気通路１８の軸心に対してほぼ直交している。
【００１２】
したがって、前記第１空気通路２２の上流端は前記給気通路１８に連通され、第１空気通路２２の下流端は空気混合路２５に連通され、第２空気通路２４の上流端は外側ガイド部材２８の中心孔２８０２を介して室内１２に連通され、第２空気通路２４の下流端は空気混合路２５に連通されている。
また、空気混合路２５の上流端は第１空気通路２２の下流端および第２空気通路２４の下流端に連通され、空気混合路２５の下流端が給気口１６の前記空気吹き出し口２０となっており、室内１２に連通している。
そして、前記空気混合路２５は、第１空気通路２２を流れる外気により第２空気通路２４に気流を生じさせると共に、第１空気通路２２を流れる外気と第２空気通路２４を流れる室内空気を混合させて空気吹き出し口２０から吹き出させるように構成されている。
【００１３】
次に、作用について説明する。
例えば、冬期、冷たい外気が給気通路１８から室内１２に流れ込む場合、最初は、冷たい外気が第１空気通路２２、空気混合路２５、空気吹き出し口２０から室内に吹き出される。
そして、冷たい外気が空気混合路２５を流れると、その誘引作用により第２空気通路２４に空気の流れが生じ、室内空気が外側ガイド部材２８の中心孔２８０２から第２空気通路２４に吸い込まれる。
第２空気通路２４に吸い込まれた室内空気は、第２空気通路２４を流れて空気混合路２５に至り、空気混合路２５において、第１空気通路２２から流出された冷たい外気と混合される。この混合された空気の温度は、冷たい外気に比べて室内温度に近づけられる。
そして、このように空気混合路２５において室内温度に近づけられた外気が空気吹き出し口２０から室内１２に吹き出される。
【００１４】
したがって、本実施の形態によれば、室内温度に近づけられた外気が室内１２に供給されるので、冬期であっても、居住者に不快感を与えることなく外気を室内に取り入れることが可能となる。
そして、不快感を与えることなく外気を室内に取り入れることができるので、給気口が閉じられてしまう不具合はなくなり、換気不足による結露やカビ、化学物質過敏症の発生を防止できる。
また、本実施の形態では、内側ガイド部材２６が給気通路１８に対してほぼ直交する方向に延在しているので、言い換えると、第１空気通路２２が給気通路１８に対してほぼ直交しているので、室外の風速(風圧)が強い場合であっても、外気を給気口２０から緩やかに吹き出させることができる。
【００１５】
また、本実施の形態では、つまみ部４００４を回転操作すれば、内側ガイド部材２６が４本のピン３８に案内されつつ壁１４に対して離間接近する方向に移動し、第１空気通路２２と第２空気通路２４の断面積が変えられるので、給気口１６から室内１２に流入される外気量の増減を調節することも可能となる。
すなわち、図５(Ａ)に示すように、内側ガイド部材２６を壁１４に近づけ、第１空気通路２２の断面積を小さく、第２空気通路２４の断面積を大きくすれば、給気口１６から室内１２に流入される外気量を少なく調節できる。あるいは、図５(Ｂ)に示すように、内側ガイド部材２６を壁１４から離し、第１空気通路２２の断面積を大きく、第２空気通路２４の断面積を小さくすれば、給気口１６から室内１２に流入される外気量を多く調節できる。無論、内側ガイド部材２６の一方の面２６Ａを壁１４に当接し第１空気通路２２を閉塞して外気の室内１２への流入を遮断することも可能であり、また、内側ガイド部材２６の他方の面２６Ｂを外側ガイド部材２８に当接し第２空気通路２４を閉塞して外気のみを室内１２に流入することも可能である。
【００１６】
また、図５(Ｂ)に示すように、第１空気通路２２あるいは混合路２５を形成する壁部部分に発熱体４６を配設し、外気の温度が低い場合に発熱体４６に通電し、発熱体４６により第１空気通路２２を流れる外気を暖め、より一層室内温度に近づけられた外気を室内１２に供給することも可能である。
なお、上記の実施の形態では、内側ガイド部材２６の全周においてその半径方向外方に、外気と室内空気を混合した空気を吹き出させるようにしたが、内側ガイド部材２６や外側ガイド部材２８の形状を適宜設定することで、互いに直交する４方向に十字状に吹き出させたり、あるいは、互いに逆向きで同一直線上に位置する２方向に吹き出させたり、あるいは、一方向のみに吹き出させるなど任意である。
【００１７】
次に、図６を参照して第２の実施の形態について説明する。
図６は第２の実施の形態に係る給気口の断面側面図を示す。
第１の実施の形態と同様な箇所部材について同一の符号を付して説明すると、第２の実施の形態の給気口１６では、第１空気通路２２２を流れる空気により第２空気通路２２４に気流を効率よく生じさせると共に、空気混合路２２５において、外気と室内空気がより効率良く混合されるように、第１、第２空気通路２２２、２２４や空気混合路２２５の形状が選定されている。具体的には、スリーブ２１９が壁１４に合わせられる部分、内側ガイド部材２２６、外側ガイド部材２２８の形状が第１の実施の形態と異なっている。内側ガイド部材２２６と外側ガイド部材２２８が、４本のピン３８と、ナット４２、雄ねじ部材４０、ピン４４を介して配設され、内側ガイド部材２２６が移動調節される点は第１の実施の形態と同様である。
【００１８】
より詳細に説明すると、給気通路１８に取着されたスリーブ２１９が壁１４に合わされる部分は、内側ガイド部材２２６の直径よりも大きな寸法の外径の環板部２１９０２として形成されており、環板部２１９０２が内側ガイド部材２２６に臨む面２１９０２Ａは凸状に形成されている。
前記内側ガイド部材２２６は、給気通路１８よりも大きな直径の円板状に形成され、その肉厚は、中央部が厚く、外周部が薄く形成され、内側ガイド部材２２６の両面２２６Ａは厚さ方向に凸状に形成されている。
前記外側ガイド部材２２８は環板状に形成され、外側ガイド部材２２８が内側ガイド部材２２６に臨む面２２８Ａは凸状に形成されている。
【００１９】
そして、前記第１空気通路２２２は、スリーブ２１９の環板部２１９０２の面２１９０２Ａと、内側ガイド部材２２６の面２２６Ａとの間の環板状の空間により形成され、第２空気通路２２４は、内側ガイド部材２２６の面２２６Ａと外側ガイド部材２２８の面２２８Ａとの間の環板状の空間により形成されている。
前記空気混合路２２５は、内側ガイド部材２２６の半径方向外方でスリーブ２１９の環板部２１９０２の面２１９０２Ａと外側ガイド部材２２８の面２２８Ａとの間の環板状の空間により形成され、空気混合路２２５の上流端はその通路の断面積が小さく、空気吹き出し口２０をなす下流端はその通路の断面積が大きく形成されている。これにより、前記空気混合路２２５は、第１空気通路２２２を流れる空気により第２空気通路２２４に気流を効率良く生じさせると共に、第１空気通路２２２を流れる外気と第２空気通路２２４を流れる室内空気を効率良く混合させるように構成されている。
【００２０】
次に、図７を参照して参考例について説明する。
図７は参考例に係る給気口の断面側面図を示す。
第１の実施の形態と同様な箇所部材について同一の符号を付して説明すると、参考例の給気口１６では、第１空気通路３２２、第２空気通路３２４、空気混合路３２５が給気通路１８と同軸上に設けられ、外気と室内空気とが混合された空気が給気通路１８の軸心上で吹き出される点が第１の実施の形態と異なっている。
前記給気口１６は、第１空気通路３２２、第２空気通路３２４、空気混合路３２５とを備えており、これら第１、第２空気通路３２２、３２４、空気混合路３２５は本実施の形態では内側ガイド部材３２６と外側ガイド部材３２８を介して形成されている。
【００２１】
前記内側ガイド部材３２６は、給気通路１８に取着されるスリーブ１９に一体に形成されたもので、給気通路１８と同軸上で壁１４から垂直に室内１２に突出する筒状に設けられている。前記内側ガイド部材３２６の基部は給気通路１８とほぼ同じ内径で形成され、内側ガイド部材３２６の先部は先端に至るにつれて次第に内径が小さくなるように傾斜して形成されている。
前記外側ガイド部材３２８は内側ガイド部材３２６よりも大きい内径の筒状に形成され、前記外側ガイド部材３２８は内側ガイド部材３２６と同軸上で内側ガイド部材３２６の半部の外側を覆うように複数のステイ５０を介して配設されている。
前記外側ガイド部材３２８の基端は壁１４から離して配置され、また、内側ガイド部材３２６の半径方向の外側に位置する部分は、大きな内径の基端から先部に至るにつれてその内径が小さくなるよう傾斜面で形成され、参考例では、内側ガイド部材３２６の前方に位置する部分は均一の内径で形成されている。
【００２２】
そして、前記第１空気通路３２２は、内側ガイド部材２６の内側の円柱状の空間により形成され、第２空気通路３２４は、内側ガイド部材３２６と外側ガイド部材３２８との間の環板状の空間により形成され、空気混合路３２５は、内側ガイド部材３２６の前方で外側ガイド部材３２８の内側の円柱状の空間により形成されている。
したがって、前記第１空気通路３２２の軸心および空気混合路３２５の軸心は、給気通路１８の軸心とほぼ同軸上に位置している。
また、前記第１空気通路３２２の上流端は給気通路１８に連通され、第１空気通路３２２の下流端は空気混合路３２５に連通され、第２空気通路３２４の上流端は外側ガイド部材３２８と壁１４との間の空間を介して室内１２に連通され、第２空気通路３２４の下流端は空気混合路３２５に連通されている。
また、空気混合路３２５の上流端は第１空気通路３２２の下流端および第２空気通路３２４の下流端に連通され、空気混合路３２５の下流端が給気口１６の前記空気吹き出し口２０となっている。
そして、前記空気混合路３２５は、第１空気通路３２２を流れる空気により第２空気通路３２４に気流を生じさせると共に、第１空気通路３２２を流れる空気と第２空気通路３２４を流れる空気を混合させて空気吹き出し口２０から吹き出させるように構成されている。
【００２３】
このような参考例によっても、例えば、冬期、冷たい外気が給気通路１８から室内１２に流れ込む場合、最初は、冷たい外気が第１空気通路３２２、空気混合路３２５、空気吹き出し口２０から室内に吹き出される。
そして、冷たい外気が空気混合路３２５を流れると、その誘引作用により第２空気通路３２４に空気の流れが生じ、室内空気が第２空気通路３２４に吸い込まれる。
第２空気通路３２４に吸い込まれた室内空気は、空気混合路３２５において、第１空気通路３２２から流出された外気と混合される。
【００２４】
この混合された空気の温度は、冷たい外気に比べて室内温度に近づけられ、このように室内温度に近づけられた外気が空気吹き出し口２０から室内１２に吹き出される。
したがって、第３の実施の形態によっても、室内温度に近づけられた外気が室内１２に供給されるので、冬期であっても、居住者に不快感を与えることなく外気を室内に取り入れることが可能となる。
そして、不快感を与えることなく外気を室内に取り入れることができるので、給気口が閉じられてしまう不具合はなくなり、換気不足による結露やカビ、化学物質過敏症の発生を防止できる。
【００２５】
【発明の効果】
以上の説明で明らかなように本発明の給気口によれば、給気口内において外気と室内空気が混合され、室内温度に近づけられた外気が室内に吹き出される。
したがって、冬期であっても、居住者に不快感を与えることなく外気を室内に取り入れることが可能となる。
また、不快感を与えることなく外気を室内に取り入れることができるので、給気口が閉じられてしまう不具合はなくなり、換気不足による結露やカビ、化学物質過敏症の発生を防止できる。

As shown in FIG. 4 (B), the outer guide member 28 has a male screw member mounting hole 34 formed therethrough, and as shown in FIG. 4 (A), the outer guide member 28 is spaced apart in the circumferential direction. The four pin mounting holes 36 are formed through. The male screw member mounting hole 34 and the four pin mounting holes 36 match the female screw 30 and the four pin insertion holes 32 of the inner guide member 26 when the inner guide member 26 and the outer guide member 28 are aligned on the same axis. It is formed in the place. The inner guide member 26 and the outer guide member 28 can be formed using a material such as wood, synthetic resin, or metal. However, when considering that the inner guide member 26 and the outer guide member 28 are likely to be condensed, wood with good heat insulation is used. And materials such as synthetic resins are preferred.
[0009]
The inner guide member 26 and the outer guide member 28 are disposed via four pins 38 and one male screw member 40.
That is, four pins 38 are erected on the wall 14 around the opening 1802 of the air supply passage 18, and these pins 38 are movably inserted into the pin insertion holes 32 of the inner guide member 26, respectively. As shown in A), the small diameter male screw portion 3802 of each pin 38 is inserted into the pin mounting hole 36 of the outer guide member 28, and the nut 42 is screwed into the small diameter male screw portion 3802 from the outside of the outer guide member 28.

When cold outside air flows through the air mixing passage 25, the air flow is generated in the second air passage 24 by the attraction action, and the indoor air is sucked into the second air passage 24 from the center hole 2802 of the outer guide member 28.
The room air sucked into the second air passage 24 flows through the second air passage 24 to the air mixing passage 25 where it is mixed with the cold outside air that has flowed out of the first air passage 22. The temperature of the mixed air is brought closer to the room temperature compared to cold outside air.

Since the cross-sectional area of the second air passage 24 is changed, it is also possible to adjust the increase / decrease in the amount of outside air flowing into the room 12 from the air supply port 16.
That is, as shown in FIG. 5A, if the inner guide member 26 is brought closer to the wall 14, the cross-sectional area of the first air passage 22 is reduced, and the cross-sectional area of the second air passage 24 is increased, the air inlet 16 Thus, the amount of outside air flowing into the room 12 can be adjusted to be small. Alternatively, as shown in FIG. 5B, if the inner guide member 26 is separated from the wall 14, the cross-sectional area of the first air passage 22 is increased, and the cross-sectional area of the second air passage 24 is decreased, the air supply port 16 The amount of outside air flowing into the room 12 can be adjusted in a large amount. Of course, it is also possible to block the first air passage 22 by making one surface 26A of the inner guide member 26 abut against the wall 14 and block the inflow of the outside air into the chamber 12, and the other side of the inner guide member 26 can be blocked. It is also possible to contact the outside guide member 28 with the surface 26B and close the second air passage 24 to allow only the outside air to flow into the room 12.
[0016]
Further, as shown in FIG. 5B, a heating element 46 is disposed on the wall portion forming the first air passage 22 or the mixing path 25, and the heating element 46 is energized when the temperature of the outside air is low, It is also possible to warm the outside air flowing through the first air passage 22 by the heating element 46 and supply the outside air that has been brought closer to the room temperature to the room 12.
In the above-described embodiment, air that is a mixture of outside air and room air is blown out radially outside the entire circumference of the inner guide member 26. However, the inner guide member 26 and the outer guide member 28 By appropriately setting the shape, it can be blown out in four directions orthogonal to each other, blown in two directions opposite to each other on the same straight line, or blown in only one direction It is.
