Abstract
Description
はじめに、空気調和装置の室内機の全体的な構造について説明する。図1は、この発明の実施の形態1にかかる空気調和装置の室内機の縦断面図である。図2は、図1のA部分を拡大して示す拡大図である。本実施の形態の室内機は、送風機4と、熱交換器(前面側熱交換器3、背面側熱交換器8)と、送風機4及び熱交換器3,8を収納する本体箱体1とを有している。
First, the overall structure of the indoor unit of the air conditioner will be described. 1 is a longitudinal sectional view of an indoor unit of an air-conditioning apparatus according to
図4は、この発明の実施の形態2にかかる空気調和装置の室内機の断面図である。本実施の形態においては、実施の形態1の延長風路21に替えて、外気(室内機の本体箱体1の外部の空気)の熱を背面板11に伝達する外気導入凹部22が設けられている。外気導入凹部22は、本体箱体1の裏面壁面1bが本体箱体1の内部側に深く断面V字状に後退する(凹む)ことで形成されている。外気導入凹部22は、背面板11の裏面を含めて形成され、本体箱体外部空間と連通し、外気を背面板11の裏面11aに直接接触させる。すなわち、外気導入凹部22は、外気の熱を背面板11に伝達する熱伝達手段を構成している。本実施の形態においては、通常、背面側熱交換器8に発生する結露水よりも温度の高い外気が、背面板11の裏面11aに直接接触するので、背面板11が暖められ、冷やされ過ぎることがなく吹出風路18に結露が発生しない。 Embodiment 2. FIG.

図5-1は、この発明の実施の形態3にかかる空気調和装置の室内機の拡大断面図である。本実施の形態においては、背面板11の熱伝導性を向上させる目的で、背面板11の裏面(外側)に、熱伝導性促進部材として金属板23Aが貼着されている。詳細には、金属板23Aは、背面板11に本体箱体1の裏面壁面1aが接合した部分の角部の外側に、両主面にかかるように折れて貼着されている。金属板23Aの材料は、例えば銅などの熱伝導性に優れた材料でなり、外気に接触れるよう少なくとも一部が本体箱体1の外気に露呈するので、外気の熱を良く吸収して背面板11に伝達する。これにより、吹出風路18の結露発生が緩和される。なお、金属板23Aを本体箱体1の外気に露呈する部分と背面板11との間に架け渡すように設けることにより、外気の熱を背面板11に伝達することができ効果的である。
FIG. 5-1 is an enlarged cross-sectional view of the indoor unit of the air-conditioning apparatus according to
図6は、この発明の実施の形態4にかかる空気調和装置の室内機の拡大断面図である。本実施の形態においては、熱伝達手段として、背面板11の裏面に板形状部材24が立設されている。板形状部材24は熱伝導性に優れた材料で作製されており、外部空気に晒されているので、板形状部材24を介して外気の熱が背面板11に良好に伝達され、背面板11が冷やされ過ぎることがなく吹出風路18に結露が発生しない。板形状部材24は、例えば熱伝導率の高い接着剤などで固着される。なお、板形状部材24の材料は、背面板11の材料より熱伝導率が高い材料であれば、所定の効果を得ることができる。
