【発明の属する技術分野】
本発明は天吊型空気調和機に関わり、詳しくは、正面斜め下向きの吹出口から送出される吹出空気が、直ちに吸込口に流入する所謂ショートサーキットを防止すると共に、外観性をよくした風向板の構造、および同風向板を駆動する駆動装置の構造に関する。
【0002】
【従来の技術】
従来の天吊型空気調和機は例えば図6および図7に示すような構造になっている。図6は内部構成を示したもので、図7は風向板を示したもである。本体21はその背面側の底面に吸込口22を設け、正面に支軸部28a を有し、回動自在に軸支した風向板28を備えた斜め下向きの吹出口23を設け、本体21内部は通風口を備えた仕切板21a により前後に区画され、前方の区画には熱交換器24とドレンパン25が配置され、後方の区画には送風口を前記熱交換器24に向けた送風機26が、前記仕切板21a の通風口に接続されたファンケーシング27に収容され配置された構成となっていた。
【0003】
前記風向板28は、例えば図7(A)で示すように、合成樹脂製からなり、ほぼ均一な板厚により平面形状に形成されたものや、図7(B)で示すように、通風抵抗を低減するため、断面形状が翼状としたものがある。
しかしながら、これらの形状の風向板28は、吹出口23から吹き出される吹出空気が矢印aで示すように下方後方に向けて送出されやすい構成となり、吹出空気が直ちに前記吸込口22に流入する所謂ショートサーキットを起こして、熱交換効率を低下させてしまうという問題を有していた。
【0004】
または、前記風向板28は、図7(C)で示すように、ほぼ均一な板厚により曲面形状に形成することにより、前記吹出口23から吹き出される吹出空気を矢印bで示すように水平方向に向けてショートサーキットを防止する反面、空気調和機の運転停止時に前記吹出口23を閉じた際、風向板28の短手方向の後部と吹出口23との間に凹凸ができてしまい外観性を損ねてしまうという問題を有していた。
【0005】
【発明が解決しようとする課題】
本発明は上記問題点に鑑みなされたもので、正面斜め下向きの吹出口から送出される吹出空気が、直ちに吸込口に流入する所謂ショートサーキットを防止すると共に、外観性を良くした風向板の構造、および同風向板を駆動する駆動装置の構造を備えた天吊型空気調和機を提供することを目的としている。
【0006】
【課題を解決するための手段】

前記風向板の裏面は、短手方向の両端部を厚肉状に形成し、表面はほぼ平面状に形成し、短手方向の両先端部を円弧状に形成した構成となっている。
【0007】
また、前記斜め下向きの吹出口を運転停止時に、前記風向板により遮蔽した時、吹出口の短手方向の両端角隅部を、前記風向板の短手方向の両端部に沿って近接するよう形成し、前記本体内側が真下から見えないようにした構成となっている。
【0008】
また、前記風向板裏面の厚肉状両端部を曲面形状に形成した構成となっている。
【0009】
また、前記風向板の表面をほぼ平面状に形成した構成となっている。
【0010】
また、前記風向板を1枚羽根または2枚羽根で形成した構成となっている。
【0011】
また、前記風向板を、枠部により前記吹出口に拡開するように支持した構成となっている。
【0012】
また、前記枠部の一側に、前記風向板を回動するための駆動装置を設け、前記風向板の少なくとも一端の支軸部が、前記枠部に設けられた軸受孔に回動自在に軸支されると共に、連係手段によって前記駆動装置に連係された構成となっている。
