【発明の属する技術分野】
本発明は、空気清浄機能を備えた空気調和機に関する。
【0002】
【従来の技術】
従来、この種空気調和機には、例えば、室内機本体に設けた吸込口及び吹出口をつなぐ通風路に、送風機、熱交換器等を設け、この熱交換器の空気流入側には、全面にわたって設けられるプレフィルタと一部に設けられる空気清浄フィルタとが配置されている。そして、吸込口から吸い込まれた空気は、比較的大きな塵や埃がプレフィルタで補足されて除去され、さらに微細な塵や埃が空気清浄フィルタで除去された後、熱交換器で熱交換されて吹出口から吹き出されるようになっている。(例えば、特許文献1参照。)。

実開平7ー12856号公報
【0004】
【発明が解決しようとする課題】
しかしながら、従来の空気清浄フィルタは、通風路断面の一部を覆うように設けられており、プレフィルタを通過し空気清浄フィルタを通らない微細な塵や埃が通風路内に侵入し、通風路の内壁や送風機のファン等に付着したり、吹出口から室内へ吹き出されるという問題があった。
【0005】
これを防ぐために、通風路断面の全体を覆うように空気清浄フィルタを設けると、空気清浄フィルタによる通気抵抗が大きくなり、十分な送風量が得られなくなるという問題があった。
【0006】
本発明の目的は、上述した従来の事情に鑑みてなされたものであり、空気清浄機能の向上を図るとともに送風量の低下を防止して熱交換効率を確保する空気調和機を提供することにある。
【0007】

【0012】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。図1は本発明の一実施形態における空気調和機の室内機の斜視図、図2は室内機の略断面図である。
【0013】
図1において、本空気調和機の室内機1は、室外に設置される室外機(図示せず)と冷媒管により接続されて、これら室外機と室内機1との間で冷媒が循環するようになっている。この室内機1は、プラスチック等を材料として形成された横長の本体ケース2と、この本体ケース2の前面上部の開口部に取り付けられる前面カバー3とを備え、前面カバー3には吸込口4が、本体ケース2の下部には吹出口5が設けられている。また、本体ケース2の右端部には空気調和機の運転停止や電気部品の動作を制御する制御装置6が設けられている。
【0014】
図2において、本体ケース2内には、前記吸込口4と吹出口5とを連通する通風路7が形成され、この通風路7内の略中心位置には、長手方向に延設されたクロスフローファン8Fを有する送風機8が設けられ、このクロスフローファン8Fと吸込口4との間に熱交換器9が配設されている。
【0015】
前記熱交換器9は、3つのブロックからなり、これら3つのブロックがクロスフローファン8Fを包むように略「く」字状及び「Λ」字状に配設されて、室内機1を小型化しても熱交換効率が低下しないようにしている。熱交換器9の下端部には、この熱交換器9で結露して滴下する水を受け止めるドレンパン12a、12bが設けられ、これらドレンパン12a、12bは本体ケース2に固定されている。
【0016】
前記前面カバー3には、吸込口4を覆うように開閉板13が設けられ、この開閉板13は左右両端に軸14、14を有し、これらの軸14、14が吸込口4の左右両端部に回動自在に枢着されている。右の軸14には駆動用モータ(図示せず)が連結され、この駆動用モータがクロスフローファン8Fの回転に連動して開閉板13を回動し、吸込口4を開放するようになっている。
【0017】
前記前面カバー3と熱交換器9との間、即ち熱交換器9の空気流入側には、開口部2aに着脱可能に設けられた収納ケース15が取り付けられている。この収納ケース15は、前側に吸い込み空気中の塵や埃を除去するフィルタ類を収納するフィルタ収納部17、後側に横並びに2つの補助送風機18、18(図1参照)を収納するモータ収納部19を備え、補助送風機18は、制御線にて制御装置6に接続されて、クロスフローファン8Fの回転に連動してファンを回転するようになっている。
【0018】
前記吹出口5には吹き出す空気の方向を設定するための風向変更器31が設けられている。この風向変更器31は吹き出す空気の左右方向を規定する縦羽根32と、上下方向を規定するフラップ33とにより構成されて、このフラップ33には回動用モータが取り付けられ、この回動用モータはクロスフローファン8Fが回転しているとき、吹出口5を開放し、回転を停止すると閉鎖するようになっている。
【0019】
図3はフィルタ収納部の断面説明図である。前記フィルタ収納部17にはフィルタ類を収納するフィルタ枠22が収納され、前から順に補助枠23、プレフィルタ24、中間枠25、空気清浄フィルタ26及び主枠27が配置されている。
【0020】
プレフィルタ24は、樹脂を網目状に加工して作られ、吸い込まれる空気中から比較的大きな埃やごみを取り除くように構成されている。
【0021】
空気清浄フィルタ26は、多数のプリーツが形成された集塵フィルタ26Sと平坦状の脱臭フィルタ26Dとを重ねた構成となっており、集塵フィルタ26Sは、平板状の補強ネットの上に電荷が付与されたポリプロピレン製不織布(商品名:シンテックスEL.三井石油化学工業株式会社)を熱融着した後、これを波形に折り曲げたものであり、脱臭フィルタ26Dは、網状ウレタンフォームに粒状活性炭を固着したものである。
【0022】
以上のように構成された空気調和機の室内機1において、クロスフローファン8Fの回転とともに空気調和機の運転が開始されると、吸込口4の開閉板13及び吹出口5のフラップ33が開放され、補助送風機18、18が作動する。吸込口4から取り込まれた空気は、プレフィルタ24、空気清浄フィルタ26を通過し、熱交換器9を通過して熱交換された後、吹出口5から吹き出される。
【0023】
ここで、吸込口4から取り込まれた空気は、プレフィルタ24により比較的大きなごみや埃が捕捉されて除去される。続いて、空気清浄フィルタ26を通過するが、空気清浄フィルタ26では、集塵フィルタ26Sにより微細な塵や埃を除去し、続いて脱臭フィルタ26Dが空気中の匂いを除去し、これにより空気を清浄化する。
【0024】
これらプレフィルタ24及び空気清浄フィルタ26は、本体ケース2の開口部2aの輪郭に沿って全面に配置しているので、室内機1に取り入れられる空気全部を通過させて空気清浄効果を高めることができる。また、クロスフローファン8Fの回転中、補助送風機18、18も連動して作動するので、通気抵抗の増大による空気量の低下を招くこともない。
【0025】
また、室内機1の吸込口4を前面だけに設け、かつ吸込口4に開閉板13を設けているので、空気調和機の運転停止中に室内機1への塵や埃の侵入をできるだけ防ぐことができる。
【0026】
このように本実施形態の室内機1は、空気清浄効果を向上させるとともに、送風量の低下を防止して冷暖房能力を確保することができる。
【0027】
なお、本発明は上述した実施形態に限定されることはなく、本発明の要旨を逸脱しない範囲で種々変形可能である。
【0028】
例えば、空気清浄フィルタは、集塵フィルタ26Sと脱臭フィルタ26Dとの2層構造とすることに限らず、集塵フィルタ26Dのみの構成であってもよい。
【0029】
また、補助送風機18にはプロペラファンを用いているが、例えばクロスフローファンを用いても良い。
【0030】
【発明の効果】
以上説明したように本発明の空気調和機の室内機は、本体ケースの前面開口部の全体に空気清浄フィルタを配置しているので、室内機に取り入れられる空気全部を清浄化して空気清浄効果を高めるとともに、補助送風機を設けているので、取り入れる空気量を確保して空調能力の低下を防ぐことができる。
