【発明の属する技術分野】
本発明は、冷凍冷蔵庫やルームエアコン等の冷凍用あるいは空調用の冷凍装置に関する。
【0002】
【従来の技術】
従来の冷凍装置は、実開平2−30878号公報に記載されたものが知られている。以下、図面を参照しながら上記従来の冷凍装置について説明する。
【0003】
図8は、従来の冷凍装置の構造を示す断面図である。図8において、1は冷蔵庫庫内の底部に配置され庫内から吸熱する蒸発装置、2は蒸発装置1の蒸発器、3は蒸発器用ファンである。4は蒸発装置1の下方に位置し吸熱した熱を庫外に放熱する凝縮装置で、5は凝縮器、6は凝縮器用ファン、7は凝縮器下方に配設されたドレン水蒸発皿を示す。また、8は圧縮機、9は減圧装置を示す。
【0004】
冷凍装置は、圧縮機8の運転により冷媒を蒸発器2、凝縮器5に流し、蒸発装置1で庫内空気を冷却、凝縮装置4で放熱する動作を行う。空調あるいは冷蔵用途の場合、蒸発器2を空気が通過し冷却される際に蒸発器2表面にドレン水が発生する。また、冷凍用途の場合でも、一旦は霜として蒸発器2表面に付着するが除霜運転によりドレン水が発生する。
【0005】
何れの場合もドレン水は、蒸発器2下に配設するドレン水受け皿(図示せず)からドレンホース(図示せず)を通りドレン水蒸発皿7まで自重で流れ込む。ドレン水蒸発皿7に溜ったドレン水は凝縮器用ファン6による送風で気中に蒸発するが、高温の凝縮器5に触れることで温度上昇しその蒸発効果は増大する。
【0006】
【発明が解決しようとする課題】
従来の冷凍装置では、凝縮装置4が蒸発装置1より下方に位置しドレン水が自重でドレン水蒸発皿7を有した凝縮装置4へ流れ込むようになっており安価な仕様でドレン水を処理できるが、凝縮装置4と蒸発装置1が水平に配設されドレン水の自重が有効に働かない場合、ドレン水受け皿からドレン水蒸発皿7までドレン水を搬送するポンプ等の手段が別途必要となってくる。
【0007】
本発明は、このように蒸発装置と凝縮装置が水平に配設された冷凍装置において、安価な仕様でドレン水をドレン水受け皿からドレン水蒸発皿まで搬送しドレン水を速やかに処理することを目的とする。
【0008】
【課題を解決するための手段】
本発明の冷凍装置においては、蒸発器と蒸発器用ファンとドレン水排出口を設けたドレン水受け皿から構成される蒸発装置と、凝縮器と前記凝縮器から風を吸い込む凝縮器用ファンと前記凝縮器と前記凝縮器用ファンの間にドレン水供給口を設けたドレン水蒸発皿から構成される凝縮装置と、前記蒸発装置のドレン水排出口と前記凝縮装置のドレン水供給口を接続するドレンホースからなるものである。
【0009】
これにより、蒸発装置と凝縮装置が水平に配設された場合でも、安価な仕様でドレン水を速やかに処理することができる。
【0010】

【0011】
請求項2に記載の発明は、請求項1記載の発明において、蒸発器用ファンが蒸発器から風を吸い込むものとしたとき、ドレン水排出口を蒸発器風上側に配設したものであり、ドレンホース両端の差圧を最大限大きくし、ドレン水受け皿からドレン水蒸発皿までドレン水をより速やかに搬送するものである。
【0012】
請求項3に記載の発明は、請求項1記載の発明において、蒸発器用ファンが蒸発器に風を送り込むものとしたとき、ドレン水排出口を蒸発器と蒸発器用ファンの間に配設したものであり、凝縮器のファンによって発生する負の静圧に加えて蒸発器用ファンによって発生する正の静圧によりさらにドレンホース両端の差圧を大きくし、ドレン水受け皿からドレン水蒸発皿までドレン水を搬送するものである。
【0013】
請求項4に記載の発明は、請求項1記載の発明において、凝縮器用ファンの風路に吸水水プレートを配設したもので、大きなスペースを必要とせずにドレン水の処理能力を向上することができる。
【0014】
請求項5に記載の発明は、請求項4記載の発明において、ドレン水供給口を、凝縮器用ファンと吸水プレートの間に配設したもので、凝縮器のファンによって発生する負の静圧を最大限有効利用できる。
【0015】
【実施例】
以下、本発明の実施例について、図1と図2を用いて説明する。
【0016】
図1は本発明の第1の実施例の冷凍装置を示すもので、冷蔵庫の底部に冷凍装置が内蔵されている。21は蒸発装置で、22は蒸発装置21の蒸発器、23は蒸発器用ファン、30はドレン水受け皿、31は風向に対し蒸発器の風上に配設されたドレン水受け皿30のドレン水排出口である。
【0017】
さらに、24は蒸発装置21の水平に位置する凝縮装置で、25は凝縮器、26は凝縮器用ファン、27は凝縮器下方に配設されたドレン水蒸発皿、28は凝縮器と凝縮器用ファンの間に配設されたドレン水蒸発皿27のドレン水供給口、29はドレン水排出口31とドレン水供給口28との間をつなぐドレンホースを示す。
【0018】
また、図中矢印は風の流れを示し、蒸発器用ファン23は蒸発器22の方向から風を吸い込むもので、凝縮器用ファン26も凝縮器25の方向から風を吸い込むものである。
【0019】
以上のように構成された冷凍装置について以下その動作を説明する。
本実施例の冷凍装置は従来の冷凍装置と同様、圧縮機(図示せず)の運転により冷媒を蒸発器22、凝縮器25に流し、蒸発装置21で庫内空気を冷却、凝縮装置24で放熱する動作を行う。蒸発器22には、冷却運転あるいは除霜運転によりドレン水が発生し、蒸発器22下に配設するドレン水受け皿30に溜るようになっている。
【0020】
以上のように構成された冷凍装置について以下その動作を説明する。
図2に蒸発装置21凝縮装置24の風路における静圧分布を示す。図2に示しように、蒸発器22の風上に配設されたドレン水排出口31の静圧はほぼ0状態で、凝縮器25と凝縮器用ファン26の間に配設されたドレン水供給口28は凝縮器用ファン26により引かれるため負の静圧状態となっている。両口がドレンホース29で接続されているため、両端に差圧△Pが発生しドレンホースを介してドレン水受け皿30に溜ったドレン水がドレン水供給口28からドレン水蒸発皿30に流れる。ドレン水蒸発皿27に流れ込んだドレン水は凝縮器用ファン26による送風で気中に蒸発するが、高温の凝縮器25に触れることで温度上昇しその蒸発効果は増大する。
【0021】
以上のように、本実施例の冷凍装置では、蒸発器22と、蒸発器側から風を吸い込む蒸発器用ファン23と、風向に対し蒸発器22の風上に配設されたドレン水排出口31を設けたドレン水受け皿30から構成される蒸発装置21と、凝縮器25と、凝縮器25から風を吸い込む凝縮器用ファン26と、凝縮器25と凝縮器用ファン26の間にドレン水供給口28を設けたドレン水蒸発皿27から構成される凝縮装置24と、蒸発装置21のドレン水排出口31と凝縮装置24のドレン水供給口28を接続するドレンホース29からなるものであり、凝縮装置24の凝縮器用ファン26によって発生する負の静圧により誘発するドレンホース29両端の差圧を利用し、蒸発装置21と凝縮装置24が水平に配設されてもドレン水受け皿30からドレン水蒸発皿27までドレン水を搬送できるものである。
【0022】
以下、本発明の第2の実施例について、図3と図4を用いて説明する。
図3は本発明の第2の実施例の冷凍装置を示すもので、冷蔵庫の底部に冷凍装置が内蔵されている。なお、第1の実施例と同一構成については、同一符号を付して詳細な説明を省略する。
【0023】
図3において、32はドレン水受け皿で、33はドレン水受け皿32のドレン水排出口で蒸発器22と蒸発器用ファン23の間に配設されている。また、図中矢印は風の流れを示し、第1の実施例と異なり蒸発器用ファン23が蒸発器22の方向に風を送り込むものである。凝縮器用ファン26は第1の実施例と同様に凝縮器25の方向から風を吸い込むものである。
【0024】
以上のように構成された冷凍装置について以下その動作を説明する。
図4に蒸発装置21凝縮装置24の風路における静圧分布を示す。図4に示すように、蒸発器22と蒸発器用ファン23の間に配設されたドレン水排出口33の静圧は、蒸発器用ファン23により風が送り込まれるので正の静圧状態となり、一方凝縮器25と凝縮器用ファン26の間に配設されたドレン水供給口28は凝縮器用ファン26により引かれるため負の静圧状態となっている。両口がドレンホース29で接続されているため、両端に差圧△Pが発生しドレンホースを介してドレン水受け皿32に溜ったドレン水がドレン水供給口28からドレン水蒸発皿30に流れる。ドレン水蒸発皿27に流れ込んだドレン水は凝縮器用ファン26による送風で気中に蒸発するが、高温の凝縮器25に触れることで温度上昇しその蒸発効果は増大する。
【0025】
以上のように、本実施例の冷凍装置では、蒸発器22と、蒸発器22に風を送り込む蒸発器用ファン23と、蒸発器22と蒸発器用ファン23の間にドレン水排出口33を設けたドレン水受け皿32から構成される蒸発装置21と、凝縮器25と、凝縮器25から風を吸い込む凝縮器用ファン26と、凝縮器25と凝縮器用ファン26の間にドレン水供給口28を設けたドレン水蒸発皿27から構成される凝縮装置24と、蒸発装置21のドレン水排出口31と凝縮装置24のドレン水供給口28を接続するドレンホース29からなるものであり、凝縮装置24の凝縮器用ファン26によって発生する負の静圧と、蒸発装置21の蒸発器用ファン23によって発生する正の静圧により誘発するドレンホース29両端の差圧を利用し、蒸発装置21と凝縮装置24が水平に配設されてもドレン水受け皿32からドレン水蒸発皿27までドレン水を搬送できるものである。
【0026】
以下、本発明の第3の実施例について、図5、図6を用いて説明する。
図5は本発明の第3の実施例の冷凍装置を示すもので、冷蔵庫の底部に冷凍装置が内蔵されている。なお、第2の実施例と同一構成については、同一符号を付して詳細な説明を省略する。
【0027】
図5、図6において、34はドレン水蒸発皿27上に配設された吸水プレートで、凝縮器25とドレン水蒸発皿27の供給口28との間に位置する。
【0028】
以上のように構成された冷凍装置について以下その動作を説明する。
蒸発器22と蒸発器用ファン23の間に配設されたドレン水排出口33の静圧は、蒸発器用ファン23により風が送り込まれるので正の静圧状態となり、一方凝縮器25や吸水プレート34と凝縮器用ファン26の間に配設されたドレン水供給口28は凝縮器用ファン26により引かれるため負の静圧状態となっている。両口がドレンホース29で接続されているため、両端に差圧△Pが発生しドレンホースを介してドレン水受け皿32に溜ったドレン水がドレン水供給口28からドレン水蒸発皿30に流れる。ドレン水蒸発皿27に流れ込んだドレン水は凝縮器用ファン26による送風で気中に蒸発するが、高温の凝縮器25に触れることで温度上昇しその蒸発効果は増大する。また、表面積の大きい吸水プレートにドレン水が吸水されることで蒸発効果はさらに増大する。
【0029】
以上のように、本実施例の冷凍装置では、蒸発器22と、蒸発器22に風を送り込む蒸発器用ファン23と、蒸発器22と蒸発器用ファン23の間にドレン水排出口33を設けたドレン水受け皿32から構成される蒸発装置21と、凝縮器25と、凝縮器25の風下に配設された吸水プレート34と、凝縮器25から風を吸い込む凝縮器用ファン26と、凝縮器25や吸水プレート34と凝縮器用ファン26の間にドレン水供給口28を設けたドレン水蒸発皿27から構成される凝縮装置24と、蒸発装置21のドレン水排出口31と凝縮装置24のドレン水供給口28を接続するドレンホース29からなるものであり、凝縮装置24の凝縮器用ファン26によって発生する負の静圧と、蒸発装置21の蒸発器用ファン23によって発生する正の静圧により誘発するドレンホース29両端の差圧を利用し、蒸発装置21と凝縮装置24が水平に配設されてもドレン水受け皿32からドレン水蒸発皿27までドレン水を搬送できるものである。また、吸水プレートを凝縮器24と凝縮器用ファン26の間に収納することで、大きなスペースを有しない。
【0030】
なお、第1、第2、第3の実施例の冷凍装置は、冷蔵庫の底部に内蔵されたもので説明したが、図7に示すように冷蔵庫の天部に据え付けるものでも同様に実施可能である。
【0031】
【発明の効果】
