Description

【0001】
【発明の属する技術分野】
この発明は、室内の壁面に取り付けて使用する空気調和機の室内機のドレンパン構造に関する。
【0002】
【従来の技術】
従来より、空気調和機の室内機は被調和室内の壁面に取り付けられて使用するものが普及している。
【0003】
この種の空気調和機に関して例えば特開平9−4869号公報に記載の空気調和機が提案されていた。
【0004】
この空気調和機の室内機のドレンパンの前側には断熱部材が設けられ、このドレンパンの前側の結露を防いでいた。
【0005】
【発明が解決しようとする課題】
しかし上述した空気調和機はそのドレンパンのドレン水の集まる溝部には断熱部材が無く、その溝部裏面の吹出口上片に結露が発生することがあった。
【0006】
そこで、本発明は、上述の点に考慮して、吹出口の上片に結露の発生することの無い空気調和機を提供することを目的とする。
【0007】
【課題を解決するための手段】
上記課題を達成するために、請求項1にかかる発明は被調和室内の空気を吸込口から吸い込み、熱交換器で冷却して吹出口から吹き出させると共に前記熱交換器で生成されたドレン水を受けるドレンパンを備え、且つ前記吹出口の上部と前記ドレンパンとを一体に設けた空気調和機の室内機において、この吹出口の上部の上片とこのドレンパンの底片との間に空間を設け、且つこのドレンパンの底片は折り曲げられて一番低い部分を溝部として、この溝部の外側下部を覆うように前記吹出口の上部の上片とこのドレンパンの底片との間に空間に断熱部材を配置して、前記熱交換器で生成されたドレン水は前記溝部に集められて室内機の外部に排出されることを特徴とする。
【0008】
請求項2にかかる発明は、底片は、熱交換器の下部に配置されていることを特徴とする。
【0009】
請求項3にかかる発明は、熱交換器の底部とドレンパンの底片との隙間を塞ぐシール部材を設けることを特徴とする。
【0010】
【発明の実施の形態】
本発明の実施例を図1及び図2を参照して説明する。図1は、本発明の実施例を示す室内機の断面説明図である。図2は、室内機のドレンパンの断面説明図である。
【0011】
図1において、1は本発明の実施例を示す空気調和機の室内機で、室外機(図示せず)とユニット間配管(図示せず)で接続されて空気調和機を構成する。
【0012】
この室内機1のケースは、前面側の前ケース20と、背面側の後ケース10とで構成されその内部に後述する風路を備えている。
【0013】
40は、室内の空気を冷却する熱交換器で、その内部を冷媒が通過することにより、冷房/除湿運転時に冷却器として機能するものである。
【0014】
50は送風ファンで、室内の空気を室内機1の風路(前ケース20の吸込口21から吸い込み、熱交換器40で冷却して再び室内に循環させる)内に導き再び室内に吹き出す。
【0015】
60は、熱交換器40からのドレン水を溜め排出するためのドレンパンである。
【0016】
66は送風ファン5で加速され再び室内に吹き出される冷風の吹出口、67は吹出口66に取付られて吹出口66から吹き出す冷風の上下風向を制御するフラップ、68は同じく左右風向を制御するブレードである。
【0017】
図2に示すように、上述したドレンパン60と吹出口66とは一体に成形され、ドレンパン60の底片60Aは折り曲げられて溝部60Bが設けられている。更にドレンパン60の底片60Aと吹出口66の上片66Aとの間に空間を設け、この空間に断熱部材61を配置している。上述した溝部60Bは、断熱部材61の上部に配置されその裏面に結露が起きないようになっている。
【0018】
ドレンパン60の底片60Aと熱交換器40の底部40Bとの隙間はシール部材62でシールされ空気がエアショートしないようになっている。
【0019】
上述したように、熱交換器40とドレンパン60とが構成されているので熱交換器40に結露したドレン水41は熱交換器40のフィン間を熱交換器40の底部40Bまで落下してドレンパン60の底片60Aに沿って溝部60Bに集まりドレンパン60の一端にあるドレンホース(図示せず)から機外へ排出される。その間ドレン水の通過する溝部60Bは断熱部材61で断熱され、溝部60Bの裏面に結露が起きないようになっている。すなわち、吹出口66の上部とドレンパン60とを一体に設け、この吹出口66の上部の上片66Aとドレンパン60の底片60Aとの間に空間を設け、且つドレンパン60の底片60Aは折り曲げられて一番低い部分を溝部60Bとして、溝部60Bの外側下部を覆うように吹出口66の上部の上片66Aとドレンパン60の底片60Aとの間に空間に断熱部材61を配置して、熱交換器40で生成されたドレン水は溝部60Bに集められて室内機1の外部に排出される。
【0020】
又、熱交換器40の底部40Bの隙間がシール部材62でシールされているので底部40Bの隙間から室内の除湿されていない空気が漏れることが無くなり吹出口66周辺での結露が少なくなる。
【0021】
断熱部材61は少なくとも熱交換器40の底部40Bの近傍まで設けておけば、その奥のドレンパン60の底片60C(吹出口66の上片66A)は熱交換器40の風下になるため結露水も少なく吹出口66の上片66Aに結露が起こる虞も少ない。
【0022】
以上説明したように、ドレンパンの底片と吹出口の上片との間に空間を設け、この空間に断熱部材を配置し、且つ底片は折り曲げられて溝部が設けられており、ドレン水はこの溝部に集められて室内機の外部に排出されることにより、吹出口の上片に結露の発生することの少ない空気調和機を提供することができる。
【0023】
なお、本発明は上述した実施例に限定されず、本発明の要旨を逸脱しない範囲で種々変形可能である。
【0024】
【発明の効果】
上記課題を達成するために、請求項1にかかる発明は被調和室内の空気を吸込口から吸い込み、熱交換器で冷却して吹出口から吹き出させると共に前記熱交換器で生成されたドレン水を受けるドレンパンを備え、且つ前記吹出口の上部と前記ドレンパンとを一体に設けた空気調和機の室内機において、この吹出口の上部の上片とこのドレンパンの底片との間に空間を設け、且つこのドレンパンの底片は折り曲げられて一番低い部分を溝部として、この溝部の外側下部を覆うように前記吹出口の上部の上片とこのドレンパンの底片との間に空間に断熱部材を配置して、前記熱交換器で生成されたドレン水は前記溝部に集められて室内機の外部に排出されるようにしたので、吹出口の上片に結露の発生しにくい空気調和機を提供することができる。
【0025】
請求項2にかかる発明によれば、底片は、熱交換器の下部に配置されていることにより、吹出口の上片に結露の発生することの無い空気調和機を提供することができる。
【0026】
請求項3にかかる発明によれば、熱交換器の底部とドレンパンの底片との隙間を塞ぐシール部材を設けることにより、吹出口の上片に結露の発生することの無い空気調和機を提供することができる。
