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。

[0011]
In FIG. 1, reference numeral 1 denotes an air conditioner indoor unit according to an embodiment of the present invention, which is connected to an outdoor unit (not shown) and an inter-unit pipe (not shown) to constitute the air conditioner.
[0012]
The case of the indoor unit 1 is composed of a front case 20 on the front side and a rear case 10 on the back side, and includes an air passage to be described later.
[0013]
Reference numeral 40 denotes a heat exchanger that cools indoor air, and functions as a cooler during the cooling / dehumidifying operation when the refrigerant passes through the heat exchanger.
[0014]
Reference numeral 50 denotes a blower fan, which directs the indoor air into the air path of the indoor unit 1 (suctioned from the suction port 21 of the front case 20, cooled by the heat exchanger 40, and circulated into the room again) and blown out into the room again.
[0015]

The gap between the bottom piece 60A of the drain pan 60 and the bottom 40B of the heat exchanger 40 is sealed with a seal member 62 so that air does not short-circuit.
[0019]
As described above, since the heat exchanger 40 and the drain pan 60 are configured, the drain water 41 condensed on the heat exchanger 40 falls between the fins of the heat exchanger 40 to the bottom 40B of the heat exchanger 40, and the drain pan. A drain hose (not shown) at one end of the drain pan 60 gathers in the groove portion 60B along the bottom piece 60A of 60 and is discharged out of the machine. Meanwhile, the groove portion 60B through which the drain water passes is thermally insulated by the heat insulating member 61 so that condensation does not occur on the back surface of the groove portion 60B. That is, the upper part of the blower outlet 66 and the drain pan 60 are integrally provided, a space is provided between the upper piece 66A of the upper part of the blower outlet 66 and the bottom piece 60A of the drain pan 60, and the bottom piece 60A of the drain pan 60 is bent. The heat insulating member 61 is arranged in the space between the upper piece 66A of the upper part of the blower outlet 66 and the bottom piece 60A of the drain pan 60 so as to cover the outer lower part of the groove part 60B with the lowest part as the groove part 60B. The drain water produced | generated by 40 is collected by the groove part 60B, and is discharged | emitted outside the indoor unit 1. FIG.
[0020]
In addition, since the gap of the bottom 40B of the heat exchanger 40 is sealed by the sealing member 62, air in the room that has not been dehumidified does not leak from the gap of the bottom 40B, and dew condensation around the outlet 66 is reduced.
[0021]
If the heat insulating member 61 is provided at least up to the vicinity of the bottom 40B of the heat exchanger 40, the bottom piece 60C (the upper piece 66A of the outlet 66) of the drain pan 60 behind it becomes the lee of the heat exchanger 40, so that condensed water is also present. There is little possibility of condensation on the upper piece 66A of the air outlet 66.
