Abstract

<P>PROBLEM TO BE SOLVED: To solve problems of room temperature rise in a case of a cold air fan of a vapor compression type when used in a closed room because heat quantity is larger in warm air than in cold air, and relative humidity rises to prohibit vaporization of water, and eliminate coldness during operation in a case of a cold air fan utilizing evaporation heat. <P>SOLUTION: This cold air fan is composed of a freezing device main body 1 including an electric compressor 2, etc., and a cooling water tank 11 separated from the freezing device main body 1 to store cooling water 12 for a condenser 3. Since heat of the condenser is discharged into the cooling water, room temperature is not raised. Since the cooling water tank is separated from the freezing device main body, it can be removed from the freezing device main body for replacement of cooling water when its temperature is raised, so that operation can be easily started without causing water to be splashed on electronic parts, etc. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明は、部屋を簡単に冷房する冷風機に関するものである。
【0002】
【従来の技術】
第1の従来の冷風機を図6に示す。この従来例は、除湿機に、局所冷暖房機能などを加えた移動可能な多機能除湿機である。図6において、本体101内に、圧縮機102と凝縮器103と蒸発器104と減圧器105の主な冷凍サイクルの要素を備え、凝縮器側送風機106により矢印108aの向きに吸込まれた室内空気は、凝縮器103を通過するときに加熱され、矢印108bのように鉛直方向または背面方向に噴出させている。一方、蒸発器側送風機107により矢印109aの向きに吸込まれた室内空気は、蒸発器104を通過する際冷却され、矢印109bのように主に前面上方に吹出され、局所的な冷房を行うものである(例えば、特許文献1参照)。
【0003】
また、第2の従来の冷風扇を図7に示す。この従来例は、気化熱を利用して冷風を吹出す冷風扇である。図7において、ファン122により矢印で示す空気が流れる方向と交差する位置に水フィルタ121を設け、本体ケース123内に空気の流れに沿って、水フィルタ121の上流側に冷却水タンク125内の水を噴霧させる超音波噴霧装置124を設けたものである。この構成によれば、A側から吸込まれた矢印で示す空気は、水フィルタ121を通過するとき、水が蒸発するときの気化熱を利用して冷却され、矢印で示す冷風となってB側に吹出されるというものである(例えば、特許文献2参照)。
【0004】
しかしながら、上記第1の従来の除湿機における構成では、同じ部屋内に冷風と同時に暖気も吹出すものである。一般に蒸気圧縮式の冷凍サイクルの場合、蒸発器側熱量(冷気)と圧縮機の入力の和が凝縮器側熱量(暖気)となることから、冷気より暖気の熱量が大きくなる。従って、除湿機を閉め切った部屋で使用すると室温は上昇してしまうため、暖気を部屋の外に排気しながら使用するか、能力の大きい空気調和機を併用しながら局所的に室温が高いところ(例えば台所)で局所冷房を行うなどの使い方しかできないという問題点を有していた。
【0005】
また、上記第2の従来の冷風扇における構成では、気化熱を利用することから運転しているうちに部屋の相対湿度が上昇し、水が蒸発できなくなってしまい冷風感がなくなってしまうため、この形態の冷風扇も換気をしながら相対湿度を下げるか、能力の大きい空気調和機を併用しながら局所的に室温の高いところ(例えば台所)で局所冷房を行うなどの使い方しかできないという問題点を有していた。

【発明が解決しようとする課題】
上記従来の技術の問題点に鑑み、本発明が解決しようとする課題は、部屋の換気をしなくても、また単独でも使用可能な冷風機を提供することにある。
【0008】
【課題を解決するための手段】
上記課題を解決するために本発明は、凝縮器の冷却用に冷凍装置本体と着脱可能な冷却水タンクを備えるものである。従って、凝縮器が冷却水タンクの冷却水に排熱することにより、冷風機を使用している部屋の室温を上げることなく冷房できる。また、冷却水の温度上昇で冷房能力が低下した場合は、冷却水タンクを着脱して水を入れ替えることにより、容易に冷房能力を回復できる。
【0009】
また、本発明は凝縮器の冷却用に冷凍装置本体と着脱可能な冷却水タンクを備えるとともに、凝縮器を水冷式凝縮器で構成し、凝縮器用の冷却水を循環させる循環ポンプを設けたことにより、凝縮器の凝縮性能を向上させて冷房能力を向上させることができるとともに、冷却水の温度上昇で冷房能力が低下した場合は、冷却水タンクを着脱して水を入れ替えることにより、容易に冷房能力を回復させることができる。
【0010】
また、本発明は前記水冷式凝縮器の冷却水を循環させる循環ポンプを、前記冷凍装置本体内に設けることで、冷却水タンクの着脱に際しての冷却水循環用のホース等の取扱いが容易になり、冷却水の交換作業が容易に行える。
【0011】
また、本発明は前記蒸発器表面に付着した結露水を前記冷却水タンクに排水する手段を有することで蒸発器に設けたた結露水用のドレンタンクが不要となり、ドレンタンクの水を捨てる手間を省くことができ、また、冷凍装置本体も小型にできる。
【0012】
また、本発明は前記冷却水タンクを、冷凍装置本体の下に設けることで結露水の排水を著しく容易にできる。
【0013】
また、本発明は冷却水の温度を測定する温度検出手段を備えることで、温度検出手段の測定信号を利用して電動圧縮機の運転を制御することが可能になり、電動圧縮機に負担をかけることなく、冷風機を運転できる。
【0014】
また、本発明は循環ポンプにより循環する冷却水の水配管に温度を測定する温度検出手段を備えることで、冷却水タンクに温度検出手段を設ける必要がなくなり冷凍装置本体内に設けることが可能になり、冷却水タンクの着脱および冷却水の交換作業に際して温度検出手段に触れないようにする気配りが不要となり、温度検出手段の断線などのトラブル回避と、冷却水タンクの取扱いが容易に行える。
【0015】
また、本発明は冷却水の温度を測定する温度検出手段の測定信号を入力し、前記温度検出手段が停止温度を測定した際に電動圧縮機の運転を停止させ、警報信号を出力する制御手段と、前記制御手段の警報信号により警報を報知するを報知手段とを備えることで、使用者が容易に運転停止している状態を把握でき、すみやかに冷却水タンクの冷却水を交換し、再運転が可能になる。
【0016】
【発明の実施の形態】
本発明の目的は各請求項に記載した構成を実施の形態の要部とすることにより達成できるので、以下には請求項1ないし8に対応する一実施例についての詳細を、図1〜図5を参照して説明し、併せて効果を述べて本発明の実施の形態についての説明とする。
【0017】
(実施の形態1)
図1は、本発明の実施の形態1における冷風機の基本構成図である。図1において、冷凍装置本体1はケース内部に冷媒配管で環状に接続して冷凍サイクルを構成した電動圧縮機2と凝縮器3と減圧機構4と蒸発器5とを設け、さらに蒸発器用送風機6を有している。冷却水タンク11は、蓋11aを開閉して凝縮器3の冷却水12の交換を行えるように構成されて冷凍装置本体1と分離されており、冷凍装置本体1と互いに着脱可能に設置台1aに載せてある。
【0018】
そして、冷却水タンク11の内部には冷却水12が入っており、凝縮器3が浸漬されている。凝縮器3は、一般に冷媒回路で用いる高圧に耐える冷媒用フレキシブル配管8で冷凍装置本体1内の冷媒配管に接続している。従って、冷却水タンク11の冷却水12の温度上昇による交換時には、蓋11aを開いて凝縮器3を冷媒用フレキシブル配管8の伸びる範囲内で冷却水タンク11より取りだし、そして冷却水タンク11のみを冷凍装置本体1と設置台1aより分離して所定の場所に運び温まった水を捨てて冷たい水を入れ、前記とは逆の順序で作業を行い、再び冷凍装置本体1と設置台1aに冷却水タンク11を設置できる構成にしてある。
【0019】
図中、9はドレンタンクで、10は水受け皿である。13はマイクロコンピュータおよびその周辺回路からなる制御手段で、点線で示す有線で電動圧縮機2の運転、停止とそれに伴う蒸発器用送風機6の制御を行うとともに、冷風機全体の運転制御を行うシーケンスを備えている。
【0020】
上記実施の形態において、制御手段13にり運転を開始すると、電動圧縮機2により圧縮された冷媒は、凝縮器3に運ばれ、冷却水タンク11内の冷却水12により冷却され、液化した後、減圧機構4により減圧され、蒸発器5に運ばれて蒸発器内で気化し、電動圧縮機2に戻る。一方、室内の暑い空気W1は蒸発器用送風機6により吸気側から蒸発器5に流入し、蒸発器5を通過する際、冷媒と熱交換し冷却され、吹出し口7より冷風W2となって吹出される。
【0021】
そして、蒸発器5を通過する際、表面に結露した凝縮水は一旦、水受け皿10で受け、その後ドレンタンク9に集められる。
【0022】
以上のように、冷風機の使用を開始すると、凝縮器3の排熱により冷却水12の温度は次第に上昇し、これに伴い凝縮器3の冷却能力は低下し、蒸発能力も低下し冷風感が損なわれる。
【0023】
然るに、本実施の形態では冷却水タンク11を冷凍装置本体1から分離可能に着脱自在にしているので、上記したように蓋11aを開いて凝縮器3を取り出して冷却水タンク11のみを取り外し、冷却水12を冷たい水に入れ替えることで容易に再運転が可能になり、冷却能力を回復させることができる。
【0024】
また、冷却水12を入れ替える時に冷却水タンク11が冷凍装置本体1と分離され、電気部品は設けられていないから、電気部品に水滴などがかかる心配もなくなり、冷却水の交換作業が容易に行うことができる。また、閉め切った部屋で使用しても冷却水温度が上昇するのみで、室温を上げることはなく、冷風感が確実に得られる。
【0025】
なお、冷風機の持ち運び性を考慮し、設置台1aにキャスター(図示せず)などを取り付け、移動しやすくする。そして、冷却水タンク11の冷却水の交換時には冷風機ごと冷却水を交換する場所に移動させて行うようにすれば、作業が一層楽になる。
【0026】
(実施の形態2)
図2は、本発明の実施の形態2における冷風機の基本構成図である。本実施の形態は、凝縮器を水冷式凝縮器で構成し、かつ凝縮器用の冷却水を循環させる循環ポンプを設けた点で実施の形態1の発明と異なり、それ以外の同一構成並びに作用効果を奏するところには図1と同一符号を付して詳細な説明を省略し、異なるところを中心に説明する。
【0027】
図2において、凝縮器は水冷式凝縮器23で構成し、そして水冷式凝縮器23の冷却水を循環させる循環ポンプ14を設けている。水冷式凝縮器23は、水と冷媒を熱交換する二重管式熱交換器で、内管(図示せず)を冷媒が、内管を内包した外管(図示せず)を冷却水がそれぞれ流れ、そして熱交換効率を高めるために前記それぞれ流れの向きは互いに対向する向きにしている。循環ポンプ14は冷却水タンク11内の往復の水配管25a、25bのうち、吸水側の水配管25aの先端に設けて冷却水タンク11の底に配置している。水配管25a、25bは水冷式凝縮器23の外管の出口、入れ口に接続されて冷凍装置本体1の側面に臨む水配管用継ぎ手18に着脱可能に接続している。従って、冷却水タンク11の冷却水12の温度上昇による交換時には、蓋11aを開いて水配管25a、25bを水配管用継ぎ手18から取外し、そして冷却水タンク11のみを冷凍装置本体1と設置台1aより分離して所定の場所に運び温まった水を捨て冷たい水を入れ、前記とは逆の順序で作業を行い、再び冷凍装置本体1と設置台1aに冷却水タンク11を設置できる構成にしてある。なお、制御手段13は循環ポンプ14を運転および停止させるための制御は点線で示す有線を通じて行うが、冷却水タンク11の着脱時に、コンセントとプラグなどの着脱手段で冷却水タンク11側との切り離しができるようにしてある。
【0028】
上記実施の形態において、電動圧縮機2により圧縮された冷媒は、水冷式凝縮器23の内管に運ばれ、水冷式凝縮器23の外管の内側を流れる冷却水と熱交換し冷却され液化した後、減圧機構4により減圧され、蒸発器5に運ばれて蒸発器内で気化し電動圧縮機2に戻る。一方、冷却水タンク11内の冷却水12は、循環ポンプ14により水配管25aを介して水冷式凝縮器23の外管に流れ、内管を流れる冷媒と熱交換した後、温められ再び水配管25bを介して冷却水タンク11に戻る。また、室内の暑い空気W1は蒸発器用送風機6により、吸気側から蒸発器5に流入し蒸発器5を通過する際、冷媒と熱交換し冷却され、吹出し口7より冷風W2となって吹き出るのである。そして、蒸発器5を通過する際、表面に結露した凝縮水は一旦、水受け皿10で受け、その後、ドレンタンク9に集められる。
【0029】
以上のように本実施の形態によれば、実施の形態1で説明した内容と同様の作用効果が得られるとともに、さらに、水冷式凝縮器23を使用し、その水冷式凝縮器23の冷却水は冷却水タンク11内の循環ポンプ14を使用して循環させているので、冷却水タンク11を取り外す際に、水配管用継ぎ手18の部分で水配管25a、25bを取り外すだけで、容易に冷却水の交換が可能となる。これにより冷媒配管を変形させることなく、かつ冷媒洩れの恐れなどを回避できる。また、水配管25a、25bでは、冷媒回路で用いる高圧に耐える冷媒用フレキシブル配管を使用することなく、低コスト化が可能となる。
【0030】
なお、本実施の形態では水冷式凝縮器23の外管を冷却水、内管を冷媒が流れるように構成したが、外管を冷媒、内管を冷却水が流れるようにしても本実施の形態と同様の効果が得られる。また、水冷式凝縮器を二重管式凝縮器で説明したが、冷媒用配管と冷却水用配管とが並行に接触しただけの熱交換器やプレート式熱交換器などを用いても本実施の形態と同様の効果が得られる。
【0031】
また、本実施の形態では冷却水タンク11の着脱時に、水配管用継ぎ手18の部分で水配管25a、25bを取り外す構成にしたが、水配管25a、25bに柔軟性のホースを使用することで水配管用継ぎ手18に接続したまま水配管25a、25bを冷却水タンク11の蓋11aを開けて取り出せるように構成しても冷却水タンク11の着脱時に対応できる。
【0032】
(実施の形態3)
図3は、本発明の実施の形態3における冷風機の基本構成図である。本実施の形態は、凝縮器用の冷却水を循環させる循環ポンプを冷凍装置本体内に設けた点で実施の形態2の発明と異なり、それ以外の同一構成並びに作用効果を奏するところには図2と同一符号を付して詳細な説明を省略し、異なるところを中心に説明する。
【0033】
図3において、水冷式凝縮器23の冷却水を循環させる循環ポンプ24は、冷凍装置本体1の内部に設け、水配管25a、25bは柔軟性のホースを使用して水配管継ぎ手8に着脱可能に接続している。
【0034】
上記実施の形態において、制御手段13により運転開始すると、電動圧縮機2により圧縮された冷媒は、水冷式凝縮器23の内管に運ばれ、水冷式凝縮器23の外管を流れる冷却水と熱交換し冷却され液化した後、減圧機構4により減圧され、蒸発器5に運ばれて蒸発器内で気化し、電動圧縮機2に戻る。一方、冷却水タンク11内の冷却水12は、冷凍装置本体1内の循環ポンプ24により水冷式凝縮器23の外管を流れ、内管を流れる冷媒と熱交換した後、温められて再び冷却水タンク11に戻る。また、室内の暑い空気W1は蒸発器用送風機6により、吸気側から蒸発器5に流入し、蒸発器5を通過する際、冷媒と熱交換し冷却され、吹出し口7より冷風W2となって吹出す。蒸発器5を通過する際、表面に結露した凝縮水は一旦、水受け皿10で受け、その後ドレンタンク9に集められる。
【0035】
以上のように本実施の形態によれば、実施の形態2で説明した内容と同様の効果が得られ、さらに、凝縮器冷却水用の循環ポンプ24を冷凍装置本体1内に備えることで、冷却水タンク11を取り外し冷却水を交換する際に、水配管25a、25bを水配管継ぎ手18に取り付けたまま、蓋11aを開けて取り出し、冷却水タンク11を所定の場所に運んで冷却水12の交換を行うことができる。従って、冷却水タンクの着脱に際しての冷却水循環用のホース等の取扱いが容易になり、冷却水の交換作業が容易に行える。
【0036】
(実施の形態4)
本発明の実施の形態4は、図3の実施の形態3における冷風機の基本構成図に、ドレン水の処理構造を付加したものであり、それ以外の構成並びに作用効果は実施の形態3の発明と同じなので、図3を利用して異なるところを中心に説明する。
【0037】
図3において、実施の形態3で説明した冷凍装置本体1内に、ドレンタンク9に、吸水側の水配管25aの途中に接続したドレンホース26を設けている。ドレンホース26には途中に弁27を設け、冷却水がドレンタンク9側に逆流するのを防止する。なお、この弁の種類としては、一方向にしか流れない逆止弁や開閉を電気的に行う電磁開閉式の二方弁などを用いる。
【0038】
上記実施の形態において、冷風機の基本的な動作、作用は実施の形態3と同様である。そして、実施の形態3の作用効果と同じような作用効果が期待できる以外に、ドレンタンク9に凝縮水が溜まってきた時にドレン水は弁27を介してドレンホース26より水配管25a側の配管に流れ込み、従来のようなドレン水を捨てる作業を省略できる。また、凝縮水は、冷たい蒸発器表面に結露した水であるため温度が低く、この温度の低い凝縮水が冷却水12と混合させることで冷却水12の温度上昇を抑制できる。
【0039】
(実施の形態5)
図4は、本発明の実施の形態5における冷風機の基本構成図である。本実施の形態は、実施の形態3で説明した冷凍装置本体1の下に、冷却水タンク41を備えたものである。そして、冷却水タンク41は冷凍装置本体1から分離可能な着脱自在に冷凍装置本体1の下に設けてある。また、蒸発器5の表面に結露した凝縮水は一旦、水受け皿10で受け、その後、柔軟性のドレンホース43を介して、冷凍装置本体1の下に設けた冷却水タンク41に直接に排水する。また、循環ポンプ24は、実施の形態3のような水配管継ぎ手を設けないで、柔軟性の水配管25a、25bを介して冷却水タンク41と連通している。
【0040】
上記実施の形態において、冷風機の基本的な動作、作用は実施の形態3と同様である。そして、実施の形態3および実施の形態4で説明した作用効果と同じような作用効果が期待できる以外に、さらに、ドレン水を排水するドレンタンクを冷却水タンク41に集約できることで、ドレン水がドレンホース43を流れ落ちて冷却水タンク41に入り、ドレンホースに弁などがなくても水受け皿10側に逆流することがない。これにより弁が不要となり、構造が単純化でき、低コスト化が図れる。
【0041】
(実施の形態6)
本発明の実施の形態6は、図1の実施の形態1における冷風機の基本構成図に、凝縮器の冷却水の温度を測定する温度検出手段を付加したものであり、それ以外の構成並びに作用効果は実施の形態1の発明と同じなので、図1を利用して異なるところを中心に説明する。
【0042】
実施の形態1で説明した冷却水タンク11内に、冷却水12の温度を測定する温度検出器61を設けている。温度検出器61は温度によって電気抵抗が変化するサーミスタで、冷却水に浸るように固定されている。制御手段13は温度検出器61からの測定信号を取りこみ、冷却水12が温度上昇して一定温度を超え、停止温度に達すると電動圧縮機2の運転を停止する制御シーケンスを実行する。
【0043】
上記実施の形態において、冷風機の基本的な動作、作用は実施の形態1の発明と同様である。そして、冷風機を運転し始めると、電動圧縮機2が運転を開始し、凝縮器3を冷却する冷却水12は温められ温度が上昇し、しだいに凝縮性能が低下する。これにより蒸発性能も低下し、冷風感が損なわれる。
【0044】
然るに本実施の形態では、制御手段13は取りこんだ温度検出器61により測定した冷却水温の信号が、一定温度を超えた場合、電動圧縮機2の運転を停止させるようにする。これにより、冷風機運転中に、冷却水温が上昇し、凝縮性能が低下し、蒸発能力が低下してきた際は、一旦、電動圧縮機2が停止するので、その後、冷却水タンク11の水を入れ替えることで、再び蒸発能力が回復し、快適に冷風機を使用することができる。
【0045】
また、冷却水の温度が極端に上昇することは、電動圧縮機2に著しく大きい負荷を与えることになり、圧縮機寿命を短くすることになるが、温度検出器61を備えることで、一定温度を超えた場合、自動的に電動圧縮機2の運転を停止させることが可能となり、長寿命化が図れるものである。
【0046】
(実施の形態7)
本発明の実施の形態7は、図2の実施の形態2における冷風機の基本構成図に、凝縮器の冷却水の温度を測定する温度検出手段を、冷凍装置本体内に設けたものであり、それ以外の構成並びに作用効果は実施の形態2の発明と同じなので、図2を利用して異なるところを中心に説明する。
【0047】
実施の形態2で説明した冷凍装置本体1内に、冷却水12の温度を測定する温度検出器71を設けている。温度検出器71は温度によって電気抵抗が変化するサーミスタで、水配管25aに取り付けられている。制御手段13は温度検出器71からの測定信号を取りこみ、冷却水12が温度上昇して一定温度を超え、停止温度に達すると電動圧縮機2の運転を停止する制御シーケンスを実行する。
【0048】
上記実施の形態において、冷風機の基本的な動作、作用は実施の形態2の発明と同様である。そして、冷風機を使用することで、電動圧縮機2が運転を開始すると、凝縮器3を冷却することで冷却水12は温められ、しだいに凝縮性能が低下する。冷却水12は循環ポンプ14により水配管25aより凝縮器23に運ばれ、温められた水は水配管25bより冷却水タンク11に戻る。
【0049】
制御手段13は、水配管25aに取り付けた温度検出器71により得た冷却水温の信号が一定温度を超えた場合、電動圧縮機2の運転を停止させる。これにより、凝縮性能が低下し、蒸発能力が低下してきた際は、すみやかに電動圧縮機2の運転を停止させ、冷却水タンク11の水を入れ替えることで、蒸発能力が回復し、快適に冷風機を使用することができる。また、冷却水の温度が極端に上昇することは、電動圧縮機2に著しく大きい負荷を与えることになり、圧縮機寿命を短くすることになるが、温度検出器71を備えることで、一定温度を超えた場合、自動的に電動圧縮機2を停止させることが可能となり、長寿命化が図れるものである。
【0050】
(実施の形態8)
本発明の実施の形態8は、図1の実施の形態1における冷風機の基本構成図に、凝縮器の冷却水の温度を測定する温度検出手段と、冷却水の交換を報知する手段を付加したものであり、それ以外の構成並びに作用効果は実施の形態1の発明と同じなので、図5のシステムのフローチャートと図1を利用して異なるところを中心に説明する。
【0051】
実施の形態1で説明した冷却水タンク11内に、冷却水12の温度を測定する温度検出器61を設けている。温度検出器61は温度によって電気抵抗が変化するサーミスタで、冷却水に浸るように固定されている。制御手段13は温度検出器61からの測定信号を取りこみ、冷却水12が温度上昇して一定温度を超え、停止温度に達すると電動圧縮機2の運転を停止する制御シーケンスを実行するとともに、制御シーケンスにより図5に示す、ステップ(以下、Sと表示する)1〜S5のフローを実行し、冷凍装置本体1の上部に取り付けた報知手段である警報ランプ81を点灯させ、冷却水の交換時期を報知する。なお、冷却水交換の時期の報知はブザーなど音で知らせても同様の効果が得られる。
【0052】
上記実施の形態において、冷風機の基本的な動作、作用は実施の形態1の発明と同様である。そして、S1で冷風機を運転し始めると、電動圧縮機2がS2で運転を開始し、凝縮器3を冷却する冷却水12は温められ温度が上昇し、しだいに凝縮性能が低下する。これにより蒸発性能も低下し、冷風感が損なわれる。
【0053】
S3で冷却水温Twを温度検出器61で検出し、冷却水温Twと停止温度Tw0とを常に比較チェイックを繰り返し、冷却水温Twが停止温度Tw0を超えた場合、S4で警報を出力させ、S5で電動圧縮機2の運転を停止させる。この警報が出力された場合、図1における警報ランプ81を点灯または点滅させることで使用者に運転が停止し、冷却水の交換時期であることを知らせることができる。
【0054】
これにより、使用者は冷風機の停止状態が冷却水温の上昇であることを容易に理解でき、冷却水タンク11を取り外し、冷却水を冷たい水に入れ替えるという適切な対応が図れ、すみやかに運転を再開させることができるとともに、再び蒸発能力が回復し、快適に冷風機を使用することができる。
【0055】
【発明の効果】
以上のように本発明によれば、冷却水タンクが冷凍装置本体から分離可能な着脱自在に設けているので、容易に冷却水タンクのみを取り外すことができ、冷たい水に入れ替えることで再運転が可能で、冷却能力を回復させることができる。
【0056】
また、水を入れ替える時に冷却水タンクが冷凍装置本体と分離されていることで、電気部品等に水滴などがかかる心配がないので、冷却水の交換作業を容易に行うことができる。
【0057】
また、凝縮器の熱を冷却水タンクに排熱することで、閉め切った部屋で使用しても冷却水温度が上昇するのみで、室温を上げることはなく、冷風感が確実に得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a cooling fan that easily cools a room.
[0002]
[Prior art]
A first conventional cold air blower is shown in FIG. This conventional example is a movable multi-function dehumidifier in which a local air conditioning function is added to the dehumidifier. In FIG. 6, a main body 101 includes main refrigeration cycle elements of a compressor 102, a condenser 103, an evaporator 104, and a decompressor 105, and indoor air sucked in the direction of an arrow 108 a by a condenser-side blower 106. Is heated when passing through the condenser 103 and is ejected in the vertical direction or the back direction as indicated by an arrow 108b. On the other hand, the indoor air sucked in the direction of the arrow 109a by the evaporator-side blower 107 is cooled when passing through the evaporator 104, and is mainly blown upward at the front surface as shown by the arrow 109b to perform local cooling. (For example, see Patent Document 1).
[0003]
FIG. 7 shows a second conventional cold air fan. This conventional example is a cold air fan that blows out cold air using heat of vaporization. In FIG. 7, a water filter 121 is provided at a position that intersects with the direction of air flow indicated by an arrow by the fan 122, and the cooling water tank 125 is disposed upstream of the water filter 121 along the air flow in the main body case 123. An ultrasonic spraying device 124 for spraying water is provided. According to this structure, the air shown by the arrow sucked from the A side is cooled by using the heat of vaporization when the water evaporates when passing through the water filter 121, and becomes the cold air shown by the arrow as the B side. (For example, refer to Patent Document 2).
[0004]
However, in the configuration of the first conventional dehumidifier, warm air is blown out simultaneously with the cold air in the same room. In general, in the case of a vapor compression refrigeration cycle, the sum of the evaporator-side heat quantity (cold air) and the compressor input becomes the condenser-side heat quantity (warm air), so the heat quantity of warm air is greater than that of cold air. Therefore, when used in a room where the dehumidifier is closed, the room temperature will rise, so use it while exhausting warm air out of the room or using a high-capacity air conditioner in a place where the room temperature is locally high ( For example, it has a problem that it can only be used for local cooling in a kitchen.
[0005]
Further, in the configuration of the second conventional cold air fan, since the relative humidity of the room rises during operation because the heat of vaporization is used, water cannot evaporate and the cold air feeling is lost. This type of cold air fan can also be used only for ventilation such as lowering the relative humidity while ventilating, or using local air conditioning in places with high room temperature (for example, a kitchen) while using a high-capacity air conditioner.

Further, the present invention has means for draining the condensed water adhering to the surface of the evaporator to the cooling water tank, so that a drain tank for condensed water provided in the evaporator becomes unnecessary, and time and effort for throwing away the water in the drain tank is eliminated. In addition, the refrigeration apparatus main body can be reduced in size.
[0012]
In addition, according to the present invention, the drainage of condensed water can be remarkably facilitated by providing the cooling water tank below the refrigeration apparatus main body.
[0013]
In addition, the present invention includes a temperature detection means for measuring the temperature of the cooling water, so that the operation of the electric compressor can be controlled using the measurement signal of the temperature detection means, and the electric compressor is burdened. You can operate the cool air machine without putting it on.
[0014]
Further, the present invention is provided with temperature detection means for measuring the temperature in the cooling water pipe circulated by the circulation pump, so that it is not necessary to provide the temperature detection means in the cooling water tank and can be provided in the refrigeration apparatus main body. Therefore, it is unnecessary to take care not to touch the temperature detecting means when attaching / detaching the cooling water tank or replacing the cooling water, and troubles such as disconnection of the temperature detecting means can be avoided and the cooling water tank can be easily handled.
[0015]
Further, the present invention inputs a measurement signal of a temperature detection means for measuring the temperature of the cooling water, and when the temperature detection means measures a stop temperature, stops the operation of the electric compressor and outputs a warning signal And notifying means for notifying an alarm by means of an alarm signal from the control means, it is possible to easily grasp the state in which the user has stopped the operation, quickly replace the cooling water in the cooling water tank, Driving becomes possible.
[0016]

Water can be exchanged. As a result, it is possible to avoid the risk of refrigerant leakage without deforming the refrigerant piping. Further, the water pipes 25a and 25b can reduce the cost without using the refrigerant flexible pipe that can withstand the high pressure used in the refrigerant circuit.
[0030]
In the present embodiment, the outer tube of the water-cooled condenser 23 is configured so that the cooling water flows and the inner tube is made to flow the refrigerant. However, even if the outer tube is made the refrigerant and the inner tube is made to flow the cooling water, the present embodiment The same effect as the form can be obtained. In addition, although the water-cooled condenser has been described as a double-pipe condenser, the present invention can be implemented using a heat exchanger or a plate-type heat exchanger in which the refrigerant pipe and the cooling water pipe are only in parallel contact. The same effect as that of the embodiment can be obtained.

This embodiment is different from the second embodiment in that a circulation pump for circulating cooling water for the condenser is provided in the refrigeration apparatus main body. The same reference numerals are attached and detailed description is omitted, and different points will be mainly described.
[0033]

[0036]
(Embodiment 4)
In the fourth embodiment of the present invention, a drain water treatment structure is added to the basic configuration diagram of the cool air blower in the third embodiment of FIG. 3, and the other configurations, functions, and effects are the same as those of the third embodiment. Since it is the same as the invention, the difference will be mainly described with reference to FIG.
[0037]
In FIG. 3, a drain hose 26 connected to the drain tank 9 in the middle of a water pipe 25a on the water absorption side is provided in the refrigeration apparatus main body 1 described in the third embodiment. The drain hose 26 is provided with a valve 27 on the way to prevent the cooling water from flowing backward to the drain tank 9 side. In addition, as a kind of this valve, the non-return valve which flows only to one direction, the electromagnetic open / close type two-way valve which electrically opens and closes, etc. are used.
[0038]
In the above embodiment, the basic operation and action of the cold air fan are the same as those in the third embodiment. In addition to the effects similar to the effects of the third embodiment, when condensed water accumulates in the drain tank 9, the drain water is connected to the water pipe 25a side of the drain hose 26 via the valve 27. It is possible to omit the conventional work of draining the drain water. Moreover, since condensed water is water condensed on the surface of a cold evaporator, the temperature is low, and the temperature rise of the cooling water 12 can be suppressed by mixing the low-temperature condensed water with the cooling water 12.
[0039]
(Embodiment 5)
FIG. 4 is a basic configuration diagram of a cold air blower according to Embodiment 5 of the present invention. In the present embodiment, a cooling water tank 41 is provided below the refrigeration apparatus main body 1 described in the third embodiment. The cooling water tank 41 is detachable from the refrigeration apparatus main body 1 and is detachably provided below the refrigeration apparatus main body 1. The condensed water condensed on the surface of the evaporator 5 is once received by the water tray 10 and then drained directly to the cooling water tank 41 provided under the refrigeration apparatus main body 1 through the flexible drain hose 43. To do. The circulation pump 24 communicates with the cooling water tank 41 via flexible water pipes 25a and 25b without providing a water pipe joint as in the third embodiment.
[0040]
In the above embodiment, the basic operation and action of the cold air fan are the same as those in the third embodiment. And besides being able to expect the same effect as the effect demonstrated in Embodiment 3 and Embodiment 4, drain water can be further concentrated by consolidating the drain tank which drains drain water to the cooling water tank 41. Even if there is no valve or the like in the drain hose after flowing down the drain hose 43, it does not flow back to the water tray 10 side. This eliminates the need for a valve, simplifies the structure, and reduces costs.
[0041]
(Embodiment 6)
Embodiment 6 of the present invention is obtained by adding temperature detection means for measuring the temperature of the cooling water of the condenser to the basic configuration diagram of the cold air fan in Embodiment 1 of FIG. Since the operational effect is the same as that of the invention of the first embodiment, a description will be made mainly on the different points using FIG.
[0042]
A temperature detector 61 for measuring the temperature of the cooling water 12 is provided in the cooling water tank 11 described in the first embodiment. The temperature detector 61 is a thermistor whose electric resistance varies depending on the temperature, and is fixed so as to be immersed in the cooling water. The control means 13 takes in the measurement signal from the temperature detector 61 and executes a control sequence for stopping the operation of the electric compressor 2 when the cooling water 12 rises in temperature and exceeds a certain temperature and reaches a stop temperature.
[0043]
In the above embodiment, the basic operation and action of the cold air fan are the same as those of the first embodiment. Then, when the cold air fan is started to operate, the electric compressor 2 starts to operate, the cooling water 12 for cooling the condenser 3 is warmed, the temperature rises, and the condensation performance gradually decreases. As a result, the evaporation performance is also reduced, and the cool air feeling is impaired.
[0044]
However, in the present embodiment, the control means 13 stops the operation of the electric compressor 2 when the cooling water temperature signal measured by the incorporated temperature detector 61 exceeds a certain temperature. As a result, when the cooling water temperature rises, the condensation performance declines, and the evaporation capacity declines during the operation of the cold air fan, the electric compressor 2 is temporarily stopped. Thereafter, the water in the cooling water tank 11 is drained. By replacing it, the evaporation capacity is restored again, and the cooler can be used comfortably.
[0045]
In addition, an extremely high temperature of the cooling water gives a significantly large load to the electric compressor 2 and shortens the life of the compressor. However, by providing the temperature detector 61, a constant temperature can be obtained. When the value exceeds the value, the operation of the electric compressor 2 can be automatically stopped, and the life can be extended.
[0046]
(Embodiment 7)
In the seventh embodiment of the present invention, temperature detection means for measuring the temperature of the cooling water in the condenser is provided in the refrigeration apparatus main body in the basic configuration diagram of the cold air fan in the second embodiment of FIG. Since the other configurations and operational effects are the same as those of the second embodiment, the description will focus on the differences with reference to FIG.
[0047]
A temperature detector 71 for measuring the temperature of the cooling water 12 is provided in the refrigeration apparatus main body 1 described in the second embodiment. The temperature detector 71 is a thermistor whose electric resistance changes depending on the temperature, and is attached to the water pipe 25a. The control means 13 takes in a measurement signal from the temperature detector 71 and executes a control sequence for stopping the operation of the electric compressor 2 when the cooling water 12 rises in temperature and exceeds a certain temperature and reaches a stop temperature.
[0048]
In the above embodiment, the basic operation and action of the cold air fan are the same as those of the second embodiment. And if the electric compressor 2 starts an operation | movement by using a cold air machine, the cooling water 12 will be warmed by cooling the condenser 3, and condensation performance will fall gradually. The cooling water 12 is conveyed from the water pipe 25a to the condenser 23 by the circulation pump 14, and the warmed water returns to the cooling water tank 11 from the water pipe 25b.
[0049]
The control means 13 stops the operation of the electric compressor 2 when the signal of the cooling water temperature obtained by the temperature detector 71 attached to the water pipe 25a exceeds a certain temperature. As a result, when the condensing performance is reduced and the evaporation capacity is reduced, the operation of the electric compressor 2 is immediately stopped and the water in the cooling water tank 11 is replaced, whereby the evaporation capacity is recovered and the cool air is comfortably cooled. You can use the machine. In addition, an extremely high temperature of the cooling water gives a remarkably large load to the electric compressor 2 and shortens the life of the compressor. If this value is exceeded, the electric compressor 2 can be automatically stopped, and the service life can be extended.
[0050]
(Embodiment 8)
In the eighth embodiment of the present invention, a temperature detecting means for measuring the temperature of the cooling water in the condenser and a means for notifying the replacement of the cooling water are added to the basic configuration diagram of the cool air fan in the first embodiment of FIG. Since other configurations and operational effects are the same as those of the invention of the first embodiment, different points will be mainly described using the flowchart of the system of FIG. 5 and FIG.
[0051]
A temperature detector 61 for measuring the temperature of the cooling water 12 is provided in the cooling water tank 11 described in the first embodiment. The temperature detector 61 is a thermistor whose electric resistance varies depending on the temperature, and is fixed so as to be immersed in the cooling water. The control means 13 takes in the measurement signal from the temperature detector 61 and executes a control sequence for stopping the operation of the electric compressor 2 when the cooling water 12 rises in temperature and exceeds a certain temperature and reaches a stop temperature. The sequence of steps (hereinafter referred to as “S”) 1 to S5 shown in FIG. 5 is executed by the sequence, the alarm lamp 81 which is a notification means attached to the upper part of the refrigeration apparatus body 1 is turned on, and the cooling water replacement time Is notified. Note that the same effect can be obtained by notifying the timing of the cooling water exchange by a sound such as a buzzer.
[0052]
In the above embodiment, the basic operation and action of the cold air fan are the same as those of the first embodiment. When the cool air fan is started to operate at S1, the electric compressor 2 starts to operate at S2, and the cooling water 12 for cooling the condenser 3 is heated and the temperature rises, and the condensation performance gradually decreases. As a result, the evaporation performance is also reduced, and the cool air feeling is impaired.
[0053]
The cooling water temperature Tw is detected by the temperature detector 61 in S3, and the comparison check is always repeated between the cooling water temperature Tw and the stop temperature Tw0. When the cooling water temperature Tw exceeds the stop temperature Tw0, an alarm is output in S4, and in S5 The operation of the electric compressor 2 is stopped. When this alarm is output, the operation is stopped by lighting or blinking the alarm lamp 81 in FIG. 1, and it is possible to inform the user that it is time to replace the cooling water.
[0054]
Thus, the user can easily understand that the cooling air temperature is stopped when the cooling air temperature is stopped, the cooling water tank 11 can be removed, and the cooling water can be replaced with cold water. In addition to being able to restart, the evaporation capacity is restored again, and the cool air fan can be used comfortably.
[0055]
【The invention's effect】
As described above, according to the present invention, since the cooling water tank is detachably provided from the refrigeration apparatus main body, only the cooling water tank can be easily removed, and re-operation can be performed by replacing it with cold water. It is possible and the cooling capacity can be restored.
[0056]
In addition, since the cooling water tank is separated from the refrigeration apparatus main body when the water is replaced, there is no concern that water droplets or the like may be applied to the electric parts or the like, so that the cooling water can be easily replaced.
[0057]
Further, by exhausting the heat of the condenser to the cooling water tank, the cooling water temperature only rises even when used in a closed room, and the room temperature is not raised, and a cool wind feeling can be obtained reliably.
