Abstract
Description
一方、図6に示すように、空気調和機101の吹き出し口103には、気流制御を行うための可動フラップ104,105が備えられている(例えば特許文献1参照)。この可動フラップ104,105を用いることで、気流を無理矢理遠くに飛ばすことも考えられるかもしれない。しかしながら、この場合、風路壁102と可動フラップ104,105との間の隙間や段差などによる圧力損失が大きいため、高効率運転を実現できないという課題がある。
実施の形態1.
図1はこの発明の実施の形態1に係る空気調和機1の構成(停止時・運転時)を示す断面図である。図1において左側が空気調和機1の前方側であり、右側が後方側である。
空気調和機1の筐体2内には、図1に示すように、熱交換器3と、当該熱交換器3により熱交換された空気を送風するファン4とが設けられている。また、筐体2の底面には、ファン4からの空気を外部に吹き出す吹き出し口5が設けられている。
空気調和機1を停止する場合には、図1(a)に示すように、前フラップ7および風路延長部8は回動機構により回転軸71,82を中心に閉方向に回動し、吹き出し口5を塞ぐ。ここで、図1(a)に示すように、風路延長部8によって吹き出し口5および前フラップ7全体を覆うことで、停止時の空気調和機1の美観を高めることができる。
実施の形態2では、実施の形態1とは別の構成により、風路長を延長する構成について説明する。
図2はこの発明の実施の形態2に係る空気調和機1の構成(停止時・運転時)を示す図である。図2に示す実施の形態2に係る空気調和機1の構成において、図1に示す実施の形態1に係る空気調和機1と同様の構成については同一の符号を付し、異なる部分についてのみ説明を行う。
また、吹き出し口5の後方側には、気流制御を行うための後フラップ9が設けられている。この後フラップ9は、不図示の回動機構により回転軸91を中心に空気調和機1の外側に回動可能に構成されている。
また、図2に示す風路壁6の段差部61bは、風路延長部8bが滑らかに移動可能なように斜面状に構成されている。そして、この段差部61bの形状に伴い、風路延長部8bの後端部81b側の底面も斜面状に構成されている。
図3に示すように、風路延長部8bの幅(長手)方向両端には、風路延長部8bを筐体2内外に移動するための移動機構83が設けられている。
図3に示す移動機構83は、風路延長部8bの上面に設けられた直線状のラック部831と、当該ラック部831と噛み合うギア部832とから構成されている。ギア部832は位置が固定されており、接続された不図示のモータにより所定方向に回転することで、ラック部831を介して風路延長部8bを所定方向に移動させる。
空気調和機1を停止する場合には、図2(a)に示すように、前フラップ7および後フラップ9は回動機構により回転軸71,91を中心に閉方向に回動し、吹き出し口5を塞ぐ。また、図2(a),3(a)に示すように、風路延長部8bは、移動機構83により筐体2内側(風路壁6面上)に移動し、筐体2内に収納される。このように、空気調和機1の停止時には風路延長部8bが筐体2内に収納された状態となるため、美観を損なうことはない。
図4に示す移動機構83は、ギア部832に変えて、当該ラック部831と噛み合うベルトコンベア833を用いたものである。ベルトコンベア833は位置が固定されており、接続された不図示のモータにより所定方向に回転することで、ラック部831を介して風路延長部8bを所定方向に移動させる。図3に示す移動機構83では、ギア部832の設置位置が段差部61bから離れるのに伴いラック部831を後方側に延長する必要があるが、図4に示すようなベルトコンベア833を用いることでラック部831を延長する必要がなくなる。
