Description

【0001】
【発明の属する技術分野】
本発明は、繰り返し移動する吸湿材を備えた軽量かつコンパクトな除湿機に関し、詳しくは、ファンにより室内空気を吸湿材に通して室内に戻し室内を除湿しながら、加熱した空気を吸湿部に通して吸湿材の水分を奪って再生を図りながら、吸湿材から水分を奪った吸湿空気から熱交換器により水を分離して回収し貯水するようにした除湿機に関するものである。
【0002】
【従来の技術】
この種の除湿機は、繰り返し移動する吸湿材と、室内空気を前記吸湿材に通した後に室内に戻して室内の除湿を行なう除湿ファンと、空気を加熱して前記吸湿材に通して水分を奪い再生させることを循環系にて繰り返す再生ヒータおよび再生ファンと、前記吸湿材に通され水分を奪い再生ヒータ側に戻される途中の吸湿空気と熱交換して水分を分離する熱交換器と、熱交換器によって分離した水を受ける水受けと、水受けの水を着脱できる貯水タンクに送り込んで貯水する貯水ポンプとを、本体に備えたものが知られている(例えば、特許文献1参照。)。
【0003】
このものは、水受け、貯水ポンプ、貯水タンクの組合せから、熱交換器にて吸湿空気から分離される水を、熱交換器の近傍に小さく邪魔なく位置する水受けによって伝い落ちや自然流下を利用して集水しながら、貯水ポンプにより貯水タンクへ送り込むようにして、貯水タンクが設置しやすさや取り扱いやすさなどによって設置位置を自由に選択されても対応でき、設計自由度が高い。
【0004】
再生ファンは前記循環系において、熱交換器と再生ヒータとの間に位置している。これにより、再生ファンは再生ヒータの上流に位置して、再生ファンに送風して加熱された高温空気を吸湿材に通して吸湿材を効率よく再生させられる。また、再生ファンは熱交換器によって冷却され除湿された後の低温な再生空気を吸引することになるので、熱や湿気の影響を受けない利点がある。

【特許文献1】

【0006】
【発明が解決しようとする課題】
しかし、この種の除湿機では、圧縮機、凝縮器、蒸発器を用いた除湿機能や除湿機による場合に比して除湿効果はまだ低い。そこで、本発明者等はさらなる除湿機能の向上を目指して、種々に実験をし、検討を重ねている。このような過程で本発明者は熱交換器から再生ファンに至る連絡路内にも結露水が付着していることに気付いた。これはその部分で循環系内外での温度差によるものと思われるが、連絡路の下部に結露水が徐々に溜まると連絡路の長手方向に広がろうとして再生ファン内に入り込み、再生ファンやその下流の再生ヒータを傷めたり、除湿性能を低下させたりする原因になることを知見した。また、このような結露は循環系の熱交換器以外の他の部分でも生じることが考えられるし、循環系内部での温度差によっても結露することが考えられる。
【0007】
本発明の目的は、熱交換器から出て再度戻る途中で結露水が発生しても再生ファンに入り込むのを防止できる除湿機を提供することにある。
【0008】
【課題を解決するための手段】
上記のような目的を達成するために、本発明の除湿機は、繰り返し移動する吸湿材と、室内空気を前記吸湿材に通した後に室内に戻して室内の除湿を行なう除湿ファンと、空気を加熱して前記吸湿材に通して除湿水を奪い再生させることを循環系にて繰り返す再生ヒータおよび再生ファンと、前記吸湿材に通され除湿水を奪い再生ヒータ側に戻される途中の吸湿空気を熱交換して除湿水を分離する熱交換器と、熱交換器によって分離した除湿水を受ける水受けとを、本体に備え、前記循環系における熱交換後の空気が熱交換器から出て、再度戻るまでの途中で発生しまたは溜まることのある部分から前記水受けに至る回収経路を設けて結露水を回収するようにしたことを特徴としている。
【0009】
このような構成では、吸湿材、除湿ファン、再生ヒータ、再生ファン、熱交換器の組み合わせにより、室内空気を吸湿材にて除湿することを循環系にて繰り返して、室内空気から吸湿して除湿を繰り返す吸湿材につき加熱した空気を通すことによって除湿水を奪い再生を図って前記室内空気に対する吸湿機能を保証しつつ、吸湿材から除湿水を奪った吸湿空気から熱交換器での熱交換によって除湿水を分離し水受けに受けることを継続して、圧縮機を用いるタイプのものよりも小型かつ軽量なものにて除湿機能を満足することができる。
【0010】
この際、熱交換後の空気が熱交換器から出て再生ヒータおよび再生ファンを経て熱交換器に再度戻る途中に、循環系内外での温度差や循環系内で生じる温度差などによって結露水が生じたり溜まったりする部分があっても、この部分から前記水受けに至る回収管路を通じて水受けに回収し、これが循環系の熱交換器以外の部分に及んで除湿機能を損なったり、機器を損なったりするようなことを防止することができる。
【0011】
本発明の除湿機は、また、繰り返し移動する吸湿材と、室内空気を前記吸湿材に通した後に室内に戻して室内の除湿を行なう除湿ファンと、空気を加熱して前記吸湿材に通して除湿水を奪い再生させることを循環系にて繰り返す再生ヒータおよび再生ファンと、前記吸湿材に通され除湿水を奪い再生ヒータ側に戻される途中の吸湿空気と熱交換して除湿水を分離する熱交換器と、熱交換器によって分離した除湿水を受ける水受けとを、本体に備え、再生ファンは前記循環系において熱交換器と再生ヒータとの間に位置し、熱交換器から再生ファンに至る連絡路に、この連絡路の内面に結露し下部に集まる結露水を受け入れる凹部を設け、この凹部に受け入れた結露水を前記水受けに回収するようにしたことを他の特徴としている。
【0012】
このような構成では、吸湿材、除湿ファン、再生ヒータ、再生ファン、熱交換器の組み合わせにより、室内空気を吸湿材にて除湿することを循環系にて繰り返して、室内空気から吸湿して除湿を繰り返す吸湿材につき加熱した空気を通すことによって除湿水を奪い再生を図って前記室内空気に対する吸湿機能を保証しつつ、吸湿材から除湿水を奪った吸湿空気から熱交換器での熱交換によって除湿水を分離し水受けに受けることを継続して、圧縮機を用いるタイプのものよりも小型かつ軽量なものにて除湿機能を満足することができる。
【0013】
この際、熱交換器から再生ファンに至る連絡路の内面に結露することがあって、結露水が連絡路の下部に集まっても、この結露水は連絡路に設けた凹部に受け入れるので、連絡路の平坦な下部に溜まって長手方向に広がろうとするのを防止することができ、再生ファンに入り込むような不都合が生じない。また、凹部に受け入れた結露水は前記水受けに回収するので、凹部の結露水が溢れて凹部がない従来と同じ状態になるのを回避することができる。凹部は除湿機が少々傾いて置かれた場合でも働きを失わない利点がある。
【0014】
凹部は前記連絡路を形成するダクトに形成する、さらなる構成では、特別な部材なしに凹部を設けることができ、その分低コスト化が図れる。
【0015】
凹部は再生ファンの上流側近傍に設ける、さらなる構成では、
連絡路の下部に集まる結露水が再生ファンの側に広がろうとしても、それを凹部に受け入れて、それ以上に再生ファンの側に及ぶのを阻止することができ、連絡路の下部のどの位置に結露水が集まっても、また広がろうとしても対応することができる。
【0016】
凹部の下に結露水の貯留室を設け、この貯留室から結露水を前記水受けへ導く回収管路を設けてある、さらなる構成では、
再生ファンの側に至ろうとする結露水を残さず受け入れられる平面広さの凹部としながら、その下に貯留室があることによって凹部を浅くかさ張らないものとし、かつ、その下の結露水の貯留室は平面的に小さくかさ張らないものにして凹部に受け入れる結露水の貯留量を多くすることができる。また、前記貯留室の結露水を回収管路による任意な経路で水受けまで導けるが、貯留量が多くなることによって、回収管路を細いものにしても回収が間に合うので配管の自由度がさらに高く設けやすい。
【0017】
熱交換器は、前記吸湿空気を、除湿ファンが吸引する室内空気と熱交換させるものである、さらなる構成では、
吸湿空気を除湿ファンが吸引する室内空気と熱交換させる熱交換器は、圧縮機を用いた蒸発器のように吸湿空気を冷やし切るには、その大きさなどから制限があって、熱交換器から再生ファンに至る連絡路に結露しやすく結露水が溜まりやすいが、上記のような構成、作用によって十分に対応することができる。
【0018】
本発明のそれ以上の目的および特徴は、以下の詳細な説明および図面の記載によって明らかになる。本発明の各特徴はそれ単独で、あるいは可能な限り種々な組合せで複合して採用することができる。
【0019】
【実施例】
以下、本発明に係る除湿機につき、図1〜図11を参照しながら詳細に説明し、本発明の理解に供する。以下の説明は、本発明の具体例を示すものであり、特許請求の範囲の記載内容を限定するものではない。
【0020】
本実施例の除湿機は、本実施例における図1、図2に全体構成を示すように、繰り返し移動する吸湿材1と、室内空気2を前記吸湿材1に通した後に室内に戻して室内の除湿を行なう除湿ファン3と、再生用の空気4を加熱して前記吸湿材1に通し除湿水を奪い再生させることを循環系Aにて繰り返す再生ヒータ5および再生ファン6と、前記吸湿材1に通され除湿水を奪い再生ヒータ5側に戻される途中の吸湿した再生用の空気4と熱交換して除湿水を分離する熱交換器7と、熱交換器7によって分離した除湿水を受ける水受け8と、を備えている。
【0021】
このような除湿機は、吸湿材1、除湿ファン3、再生ヒータ5、再生ファン6、熱交換器7の組み合わせにより、室内空気2を吸湿材1にて除湿することを循環系Aにて繰り返す。この際、室内空気2から吸湿して除湿を繰り返す吸湿材1につき加熱した再生空気4を通すことによって除湿水を奪い再生を図って前記室内空気2に対する吸湿機能を保証しつつ、吸湿材1から除湿水を奪った吸湿空気4aにつき熱交換器7での熱交換によって除湿水を分離して再生空気4に戻し、分離した水は水受け8に受けることを継続する。これによって、圧縮機を用いるタイプのものよりも小型かつ軽量なものにて除湿機能を満足することができる。
【0022】
特に、本実施例では、再生ファン6は図1、図2に示すように循環系Aにおいて熱交換器7と再生ヒータ5との間に位置し、熱交換器7から再生ファン6に至る連絡路101に、この連絡路101の内面に結露し下部に集まる結露水を受け入れる図8に示すような凹部102を設け、この凹部102に受け入れた結露水を前記水受け8に回収するようにする。
【0023】
これにより、前記のような除湿動作の際、熱交換器7から再生ファン6に至る連絡路101の内面に結露することがあって、結露水が連絡路101の下部に集まっても、この結露水は連絡路101に設けた凹部102に受け入れるので、連絡路101の平坦な下部に溜まって長手方向に広がろうとするのを防止することができる。従って、再生ファン6に結露水が入り込むような不都合は生じない。また、凹部102に受け入れた結露水は前記水受け8に回収するので、凹部102の結露水が溢れて凹部102がない従来と同じ状態になるのを回避することができる。このような凹部102は除湿機が少々傾いて置かれた場合でも働きを失わない利点がある。
【0024】
このような凹部102は図示するように連絡路101の下部、特に、最低位部に設けるのがよく、連絡路101が横断面円形であることによって、周方向の最下部としている。しかし、最下部は連絡路101の横断面形状や軸線方向の形状、傾斜の有無などによって変化する。図1〜図8に示す例、図9に示す例では、連絡路101の周方向最下部で、しかも、再生ファン6の上流側近傍に凹部102を設けてある。このような再生ファン6の近傍位置では、連絡路101の下部に集まる結露水が再生ファン6の側に広がろうとしても、それを凹部102に受け入れて、それ以上に再生ファン6の側に及ぶのを阻止することができる。従って、連絡路101の下部のどの位置に結露水が集まっても、また広がろうとしても対応することができる。
【0025】
このような凹部102を設けるのに、例えば前記連絡路101をなすダクト103に形成すると、特別な部材なしに凹部102を設けることができ、その分だけ低コスト化が図れる。しかし、このようにすると、ダクト103が筒部材であって、これを型成形するときの型抜き構造が凹部102のために複雑になったりする。そこで、図1〜図8に示す例では、上流側半部102aをダクト103と一体に形成し、残りの下流側半部102bを別体に形成し、半部102aに半部102bを合体させるようにしている。このようにすると、ダクト103と一体成形する上流側半部102aが、ダクト103の下流側端部に向け開放した形態となるので、型の上流側半部102aを形成する部分はダクト103の軸線に沿って下流側の方向に向けて単純に型抜きすることができる。残る下流側半部102bはそれ単体であるので、もとより型抜きの問題はない。
【0026】
図1〜図8に示す例では、さらに、凹部102の下に図1、図2、図3、図8に示すような結露水の貯留室104を設け、この貯留室104から結露水を前記水受け8へ導く回収管路105を設けてある。これによって、凹部102は再生ファン6の側に至ろうとする結露水を残さず受け入れられる平面広さのものとしながら、その下に貯留室104があることによって凹部102を浅くかさ張らないものとすることができる。同時に、その下の結露水の貯留室104は平面的に小さくかさ張らないものにして凹部102に受け入れる結露水の貯留量を多くすることができる。また、貯留室104の結露水を回収管路105による任意な経路で水受け8まで導けるが、貯留量が多くなることによって、回収管路105をかさ張らず、また屈曲度が高くなる細いものにしても回収が間に合うので配管の自由度がさらに高く設けやすい。
【0027】
凹部102の下にこのような深い貯留室104を設けるのに、前記凹部102を上流側半部102aと下流半部102bとに分割して形成したことに関連して、貯留室104の部分をも上流側部分104aおよび下流側部分104bに分割して図8に示すように凹部102の上流側部分102aと下流側部分102bとに振り分け容易に一体形成することができる。これにより、型抜き構造を複雑にして一体成形するよりは容易かつ安価に成形することができる。
【0028】
貯留室104の回収管路105との接続口104cは、成形が容易な側となる下流側部分104bに筒状に一体形成し、この接続口104cに回収管路105を接続している。
【0029】
さらに、図8に示す例では、連絡路101の後部端に再生ファン6の吸引口6cが内嵌めした状態としてあって、凹部102の再生ファン6側に段部111を形成していて、この段部111が堰きとなって連絡路101の下部に集まり再生ファン6の側に広がろうとする結露水を堰き止められるので、凹部102と協働して再生ファン6への結露水の侵入をさらに防止しやすくする。
【0030】
もっとも、連絡路101の下部を、周方向に加え、長手方向にも凹部102に向かって下がり勾配の傾斜を設けるなどして、連絡路101の下部に集まる結露水を凹部102に誘導できるようにすることもできる。
【0031】
図9に示す凹部102の別の例では、図示するように凹部102は熱交換器7の排出口7dにまで面一の状態で達している。これにより、凹部102に受け入れた結露水が溜まって連絡路101の長手方向に広がろうとしても、再生ファン6の側への広がりを堰き止めるので、専ら熱交換器7側にだけ広がるように規制することができる。この結果、凹部102に受け入れた結露水は熱交換器7内に戻して水受け8に受けられ回収されるようにすることができる。従って、この場合、特別な回収管路などが不要となるし、オーバーフローの心配がない。
【0032】
図10に示す他の例では、凹部を省略し、連絡路101の下部壁を熱交換器側に下向きとなる傾斜を持たせて、連絡路101の下部に集まる結露水が熱交換器側に流れ落ちるようにしてある。このような傾斜は連絡路101の下部だけか、全体の傾斜、テーパー形状などによって形成することができる。テーパー形状の場合は連絡路101の上部側に結露する結露水は再生ファン6側に伝い落ちる傾向があるので、後端部に垂下壁を設けてそれを堰き止め、傾斜した下部に滴下するように規制するのが好適である。
【0033】
図1〜図8に示す例の除湿機の熱交換器7は、前記吸湿空気4aを、除湿ファン3が吸引する室内空気2と図1、図2に破線で示すように熱交換させる。このため、熱交換器7は図2、図3に示すような多数の分岐空気通路7aを例えば並列な状態で途中に持った熱交換エレメント7bを複数接続して、吸湿空気4aを導入し、分岐空気通路7aの外側を通過する室内空気2と熱交換させるようにしている。熱交換エレメント7bは樹脂製のブロー成形品であるが、壁厚が薄いので熱交換は図れる。しかし、室内空気2との熱交換であるため、圧縮機を用いた蒸発器のように吸湿空気を冷やし切るには、その大きさなどから制限があって、熱交換器7から再生ファン6に至る連絡路101に結露しやすく結露水が溜まりやすい。また、連絡路101は熱交換器7において、吸湿材1が介在しているものの再生ヒータ5を設置し、また、循環系Aにて比較的近い位置で繋がっているので、内部温度が高くなって結露を招きやすいこともある。しかし、上記のような結露水の回収構造とその作用によって十分に対応することができる。
【0034】
図1〜図8に示す例の除湿機につき、さらに詳述すると、水受け8に回収した除湿水や結露水を貯水するための図1に示すような着脱できる図2に示すような貯水タンク9と、この貯水タンク9に水受け8の除湿水や結露水を送り込んで貯水させる図6に示すような貯水ポンプ11とを備えている。吸湿材1、除湿ファン3、再生ヒータ5、再生ファン6、熱交換器7の組み合わせからなる循環系A、水受け8および貯水ポンプは、除湿機の本体12に例えば図1、図2に示す内部機器16などとして備え、貯水タンク9は本体12に着脱できるように装着するようにしている。
【0035】
これにより、本体12側に備えた循環系Aにて除湿機能を発揮しながら、吸湿材1を再生した後の吸湿した再生空気4から分離した除湿水、および連絡路101での結露水は、同じく本体12側に備えた水受け8で受けることにより広域に拡がらせないで貯水ポンプ11による貯水タンク9への送り込みと貯水に供して、本体12の必要スペースを最小限に抑えて満杯回避により長時間の除湿を可能としながら、分離した除湿水が蒸発、逸散して室内を却って加湿してしまうような不都合を防止することができる。貯水ポンプ11から貯水タンク9への図2、図6に示すような送水路26はどのように構成し、どのように接続してもよいが、貯水タンク9の上部から流し込むのが逆流が生じないので好適である。しかし、送水路26の途中や貯水タンク9の送水路26を着脱できるように接続する部分に逆止弁を設ければ逆流による問題は解消する。また、貯水ポンプ11または専用の図示しないポンプなどによって、凹部102に溜まる結露水を水受け8や貯水タンク9に送り込むようにもできる。
【0036】
特に、貯水タンク9は本体12の上部の前面側に設けている。このようにすると、貯水タンク9は図1に示すように本体12の上部の前面側にあることによって、前記のように水受け8に集められる除湿水の送り込みを受けて貯水し、これが本体12のユーザに近い前部まわりから外観されるようにすることができる。つまり、室内空気2を除湿することによって除湿水が生じ、これが貯水タンク9に貯水されたことをユーザーが確認できることによって除湿が実感され、評価されやすくすることができる。しかも、本体12に設ける貯水タンク9の形状および大きさを本体12側の機器の配置による余剰スペースに対応させることにより、無駄なスペースができたり不自然な窪みや飛び出しをなくして貯水タンク9を設けることができる。同時に、貯水タンク9に関し排水したり、洗浄などの手入れをしたりするのに、本体12外の、しかも前記ユーザーの最も近くで、かつ着脱しやすい側に貯水タンク9が位置しているので、貯水タンク9を単独に容易に取り扱って対応することができる。
【0037】
もっとも、これには貯水タンク9が無色または有色の透明、半透明か、乳白色などの不透明でも内部の貯水やそのレベルの影が外面に反映して外部から確認できるか、あるいは、部分的にでもそのような貯水やそのレベルを確認できる貯水点検部があればよい。このような貯水タンク9やその部分は硝子や合成樹脂によって得られるが、軽量性、破損性の面にて合成樹脂製とするのが好適である。本体12は前記のような多種多様な機器を装備するもので、耐久性上や耐熱性上からその全体または一部を金属製とすることができるが、これに限られることはなくその一部または全体を合成樹脂製とすることができる。また、合成樹脂製でも耐熱樹脂材料によって必要に応じ耐熱性は得られる。

また、図1に示すように、本体12の貯水タンク9の下、つまり貯水タンク9を設ける設置部の下、図示する例では図2に示すような前記段部15の下に、前側から順に、熱交換器7、回転する吸湿材1が位置し、吸湿材1の後ろの上下に再生ヒータ5および再生ファン6が位置して、再生用の空気4が再生ファン6から、再生ヒータ5、吸湿材1、熱交換器7に順次至って後、再生ファン6に戻る循環系Aをなしている。これら再生ヒータ5および再生ファン6の後ろに除湿ファン3がその吸気口3aを吸湿材1を介して本体12の前面の吸気口22に向け開口し、送風口3dを本体12上部の排気口23に繋がるようにして位置している。
【0039】
水受け8は図2、図6に示すような蓋8aを有し、前記熱交換器7にて吸湿空気4aから分離した除湿水、ないしは結露水はこの蓋8aの通水部8bを通じて受け入れる。また、前記凹部102からの回収管路105もこの蓋8aに接続して凹部102からの結露水が水受け8に受け入れられるようにしている。貯水ポンプ11は図3、図6に示すように水受け8の底部から貯水タンク9に至る送水路26の基部側途中に設けてある。また、図示する例では吸気口22の内側に図1、図2に示すようなフィルタ93が設けられている。吸湿材1は図1、図2に示すように、ゼオライトなどの吸湿剤1aを収容保持したケース1bにギヤ1cを設け、このギヤ1cに図3、図4に示すようなギヤドモータ71に直結するなどしたピニオンギヤ72を噛み合わせることによって所定の速度で回転駆動するようにしてある。
【0040】
以上のような内部機器16の配置により、吸湿材1が回転して繰り返し室内空気2の除湿とその後の再生を行うので、前記除湿と再生のための室内空気2の図1に示す通過方向に厚みが向く扁平なものでよくなり、その前部に位置する熱交換器7とともに本体12上部の前側に設けられる貯水タンク9の平面スペースを利用した下側に位置して、前後方向および上下方向に無駄なスペースなく設置できる。また、これら上部の貯水タンク9、その下部の熱交換器7および吸湿材1と、これらの後方に位置した再生ヒータ5および再生ファン6とで、互いが無駄に分散するようなことなく前記循環系Aを、これを収納する本体12部分とともに例えば図1、図2に示すようにコンパクトに構成しながら、この循環系Aの後ろに本体12の高さ一杯を利用した図1に示すような十分な大きさの除湿ファン3を、本体12を特に大型化したりしないで設けて、十分な風量と、静かで人に風を感じさせない程度の低速吸気、および低速送風とを確保して、高い除湿機能を発揮することができる。しかし、広域の除湿には吸気および送風のうち少なくとも一方は除湿の必要な範囲まで及ぶ条件を満足する必要がある。
【0041】
本体12内は図1、図2に示すように除湿ファン3を収容した後部と、循環系Aを収容した前部とを合成樹脂製の仕切り壁75によって仕切っている。仕切り壁75は本体後部側に除湿モータ3eを取り付け、そのまわりに吸気口3aを形成している。除湿モータ3eに直結した除湿羽根車3bは後部側に位置して、仕切り壁75に取り付けた合成樹脂製のカバー壁3cで覆い除湿ファン3を構成している。また、本体12の前部側には、さらに、吸湿材1側と熱交換器7側とを仕切る図1、図2、図3、図4、図5に示すような合成樹脂製の仕切り壁77を設けている。仕切り壁77はその中央に吸湿材1を図1、図2に示す軸部77aによって回転できるように支持するとともに、前記ギヤドモータ71を取り付け、吸湿材1を仕切り壁77上で回転駆動するようにしている。
【0042】
仕切り壁75、77間には除湿モータ3eのほか、前記再生ヒータ5および再生ファン6が位置している。再生ヒータ5は仕切り壁77に取り付けた図2に示すような加熱部カバー73の後部にある流入口73a内に保持し、加熱部カバー73が前部側に向け、上下左右にラッパ形に広がって形成する流出口73bを吸湿材1の再生を図る範囲に対し、図11に示すような適当な隙間Sを持って対向させている。加熱部カバー73の前記のようなラッパ形状は、小さな流入口73aにて再生ヒータ5と再生空気4との効率のよい接触とそれによる加熱を達成した後、十分に昇温した再生空気4を可能な限り加熱部カバー73の後部には再生ファン6からの再生空気4を吸湿材1のより広域に通風させて、効率のよい再生が図れるようにしている。加熱部カバー73の後部には、再生ヒータ5に導いた後、吸湿材1を通過させる、図1、図2、図3、図4に示すような再生カバー74を設けてあり、加熱部カバー73とともに仕切り壁77に取り付けてある。再生カバー74は図2に示すように加熱部カバー73の全体を覆った状態で再生空気4を再生ヒータ5に送風するようにしてあり、加熱部からその後側まわりへの熱影響を防止する遮熱カバーにもなっている。
【0043】
再生ファン6は羽根車6aを収容したケーシング6bの吸引口6cが、図1、図8に示すように仕切り壁77に一体成形した連絡路101のダクト103における後部端に図示するように嵌め合わせるなどして接続してあり、ケーシング6bの吹き出し口6dを図2、図3、図4に示すように再生カバー74の導風口74aに接続してある。
【0044】
ここで、再生ファン6から再生ヒータ5に至る経路、たとえば再生カバー74は図3、図4に示すように、下部が低位部74cに向かう傾斜部74dを有し、温度差などにより万一にも結露水が生じたり、あるいは侵入することがあっても、それを低位部74cに誘導し、結露水が循環系Aを循環して除湿効率を低下させたり、他に影響したりするのを防止することができる。このような結露水が極少ないと低位部74cに至る途中、または至ってから乾燥し発散されるようにすることができる。しかし、それが徐々に増量するような場合は、低位部74cから図2、図3に示すような回収管路112を通じるなどして水受け8へ回収するようにもできる。
【0045】
循環系Aにおいて凹部102と再生カバー74の傾斜形状による低位部74c、および結露水の回収部など、必要な部分以外に、結露水が溜まったり、流れたりする個所を設けないでおくことで、結露水が不用意な部分に流れたり、溜まったりして他に影響するようなことを防止することができる。
【0046】
ところで、循環系Aにおける熱交換後の再生空気4が熱交換器7から出、再生ヒータ5および再生ファン6を経て再度戻る途中、つまり熱交換器7以外の部分でも、循環系A内外の温度差、あるいは内部での温度差、あるいは何らかの理由によって結露水が発生したり、溜まったりすることが考えられる。そこで、そのような部分ないしはそれに続く溜まり部から前記水受け8に至る回収管路112を設けて回収するようにするのが好適である。このような溜まり部および回収管路112を含む回収経路はどのようにも形成することができる。
【0047】
仕切り壁77は、さらに、図1、図2に示すように、吸湿材1に対応する部分を前部側に開放して、再生ファン6によって吸引される室内空気2を吸湿材1に通風させる通風口78と、吸湿材1の前部側で再生ヒータ5、吸湿材1を通過し、吸湿材1を再生させた後の吸湿空気4aを受け入れる図2、図11に示すような受入室79を形成している。受入室79はその後端が吸湿材1と図11に示すような隙間Sを持って対向して吸湿空気4aを受入れ、前部には前記熱交換器7における導入口7cとの接続口80を設けて受け入れた吸湿空気4aを熱交換器7に送り込むようにしてある。熱交換器7の図1に示す排出口7dは図1に示すように連絡路101をなすダクト103の前端部に接続して、吸湿空気4aを室内空気2との熱交換によって除湿し、再生した再生空気4が再生ファン6によって吸引され、吸湿材1の再生に再度供されるようにしている。
【0048】
本体12の後部上面には図2に示す操作面28と除湿ファン3からの排気口23とを横に並ぶように併設している。排気口23は本体12の上面への矩形な開口23aと、本体12の背面への開口23bとが連続した状態に形成してあり、開口23aに軸64により開閉できるように枢支した風向設定蓋65を設け、操作面28にて設定した風向状態になるように図示しないモータなどのアクチュエータにより駆動するようにしてある。風向設定は例えばほぼ鉛直な全閉状態と、この全閉状態から図2に示す全開状態との間の各中間開き状態と、全閉状態と全開状態との間を連続的に往復する風向連続変更状態とがある。全閉状態では開口23bだけが後方向に開かれた状態で、後ろ向き送風となる。全開状態では開口23aの全域が開口されて真上への送風となる。各中間開き状態では風向設定蓋65の開き角度に沿った方向への送風となる。
【0049】
本体12には、さらに、図2に示すように、本体12の側方から見て貯水タンク9と対角線上の位置となるコーナ部の左右両側にキャスタ33を設けてある。これにより、本体12を左右一対のキャスタ33にて接地して引き回すのに、前記対角線が鉛直となる側に本体12を後ろ側に倒すと、本体12の貯水タンク9を含む重心をキャスタ33上に位置させられるし、貯水タンク9での貯水量の違いでその時々で前記重心の位置が異なっても、本体12の後ろ側への倒し角度を調節することによって重量を前後にバランスさせて難なく移動させられ、同一の居室内は勿論、居室間、居室と風呂場など場所を移して使用するような場合に便利である。風呂場ではそれ自体の除湿、乾燥はもとより、洗濯物の乾燥にも供することができる。
【0050】
なお、本体12の底部には使用状態に接地する座部の1つの例として座脚35を設けてあり、図2に示すようにキャスタ33を設置面36から少し浮かせて本体12を設置するようにしてある。これにより、本体12を使用状態に設置している状態ではキャスタ33は接地せず本体12の設置状態を不安定にするようなことはない。
【0051】
前記キャスタ33を設けるのに併せ、本体12の背面には図1、図2に示すように、上下方向に出し入れできる引き手37を設けてある。図示する例の引き手37は本体12の背部の左右方向の中央部に縦向きに設けた鞘部39に出し入れできるように保持された左右一対の引き棒37aと、これら引き棒37aの上端に取り付けられたグリップ37bとで構成している。このような引き手37は本体12を前記のように後ろ側に倒して引き回すときの、本体12の支え、角度調節、引き回しのそれぞれに共用して、容易かつ自在に移動できる。なお、貯水タンク9の上部には図示しない起伏できるように枢支した手提げハンドルを設けるのが好適である。
【0052】
なお、図11に示す加熱部カバー74および受入室79と吸湿材1との間の隙間Sは、吸湿材1が回転駆動されても他と干渉しないためのものである。しかし、この隙間Sは再生空気4と吸湿空気4aとが混合してしまう隙間Sともなり、除湿効率が低下する原因になる。そこで、本実施例では再生ヒータ5として半導体ヒータであるPTCヒータを採用し、これが最大で200℃程度とリボンヒータのような高温にならないのを利用して、前記加熱部カバー73および受入室79と吸湿材1のケース1bとを合成樹脂製とするとともに、それらの熱膨張および成形誤差によっても互いが接触し合わない最低隙間S1を確保し、再生空気4と吸湿空気4aとの混合を最小限に押えられるようにしている。特に、加熱部カバー73とケース1bとの隙間S1は、ケース1bの吸湿材受けフランジ1eと、その内周と嵌り合う加熱部カバー73側の凸部73fとの間、前記フランジ1eの後端面と、この後端面に前記凸部73fの外まわりで対向する加熱部カバー73の前端面との間で、形成する横断面鉤型の間隙部としてあり、これがいわゆるラビリンス隙間S1となって、吸湿空気と再生空気との混合をさらに防止しやすくしている。受入室79と吸湿材1のケース1bとの間の隙間S1は、受入室79の後端と、ケース1bに取り付けた押え金具121との間でストレートに形成している。しかし、この部分でもラビリンス隙間としてもよい。
【0053】
【発明の効果】
本発明の除湿機によれば、吸湿材、除湿ファン、再生ヒータ、再生ファン、熱交換器の組み合わせにより、室内空気を吸湿材にて除湿することを循環系にて繰り返して、室内空気から吸湿して除湿を繰り返す吸湿材につき加熱した空気を通すことによって除湿水を奪い再生を図って前記室内空気に対する吸湿機能を保証しつつ、吸湿材から除湿水を奪った吸湿空気から熱交換器での熱交換によって除湿水を分離し水受けに受けることを継続して、圧縮機を用いるタイプのものよりも小型かつ軽量なものにて除湿機能を満足することができる。
【0054】
この際、熱交換後の空気が熱交換器から出て再生ヒータおよび再生ファンを経て熱交換器に再度戻る途中に、循環系内外での温度差や循環系内で生じる温度差などによって結露水が生じたり溜まったりする部分があっても、この部分から前記水受けに至る回収管路を通じて水受けに回収し、これが循環系の熱交換器以外の部分に及んで除湿機能を損なったり、機器を損なったりするようなことを防止することができる。
【0055】
本発明の他の特徴の除湿機によれば、吸湿材、除湿ファン、再生ヒータ、再生ファン、熱交換器の組み合わせにより、室内空気を吸湿材にて除湿することを循環系にて繰り返して、室内空気から吸湿して除湿を繰り返す吸湿材につき加熱した空気を通すことによって除湿水を奪い再生を図って前記室内空気に対する吸湿機能を保証しつつ、吸湿材から除湿水を奪った吸湿空気から熱交換器での熱交換によって除湿水を分離し水受けに受けることを継続して、圧縮機を用いるタイプのものよりも小型かつ軽量なものにて除湿機能を満足することができる。
【0056】
この際、熱交換器から再生ファンに至る連絡路の内面に結露することがあって、結露水が連絡路の下部に集まっても、この結露水は連絡路に設けた凹部に受け入れるので、連絡路の平坦な下部に溜まって長手方向に広がろうとするのを防止することができ、再生ファンに入り込むような不都合が生じない。また、凹部に受け入れた結露水は前記水受けに回収するので、凹部の結露水が溢れて凹部がない従来と同じ状態になるのを回避することができる。凹部は除湿機が少々傾いて置かれた場合でも働きを失わない利点がある。
【0057】
凹部を前記連絡路を形成するダクトに形成する、さらなる構成によれば、特別な部材なしに凹部を設けることができ、その分低コスト化が図れる。
【0058】
凹部を再生ファンの上流側近傍に設ける、さらなる構成によれば、連絡路の下部に集まる結露水が再生ファンの側に広がろうとしても、それを凹部に受け入れて、それ以上に再生ファンの側に及ぶのを阻止することができ、連絡路の下部のどの位置に結露水が集まっても、また広がろうとしても対応することができる。
【0059】
凹部の下に結露水の貯留室を設け、この貯留室から結露水を前記水受けへ導く回収管路を設けてある、さらなる構成によれば、再生ファンの側に至ろうとする結露水を残さず受け入れられる平面広さの凹部としながら、その下に貯留室があることによって凹部を浅くかさ張らないものとし、かつ、その下の結露水の貯留室は平面的に小さくかさ張らないものにして凹部に受け入れる結露水の貯留量を多くすることができる。また、前記貯留室の結露水を回収管路による任意な経路で水受けまで導けるが、貯留量が多くなることによって、回収管路を細いものにしても回収が間に合うので配管の自由度がさらに高く設けやすい。
【0060】
熱交換器は、前記吸湿空気を、除湿ファンが吸引する室内空気と熱交換させるものである、さらなる構成によれば、吸湿空気を除湿ファンが吸引する室内空気と熱交換させる熱交換器は、圧縮機を用いた蒸発器のように吸湿空気を冷やし切るには、その大きさなどから制限があって、熱交換器から再生ファンに至る連絡路に結露しやすく結露水が溜まりやすいが、上記のような構成、作用によって十分に対応することができる。
【0061】
本発明のそれ以上の目的および特徴は、以下の詳細な説明および図面の記載によって明らかになる。本発明の各特徴はそれ単独で、あるいは可能な限り種々な組合せで複合して採用することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lightweight and compact dehumidifier provided with a moisture absorbing material that moves repeatedly, and more particularly to a method in which heated air is passed through a moisture absorbing portion while returning indoor air to a room by a fan and returning the indoor air to the room. The present invention relates to a dehumidifier in which water is separated from a hygroscopic air from which moisture has been deprived from a hygroscopic material by a heat exchanger to collect and store the water while depriving the moisture of the hygroscopic material for regeneration.
[0002]
[Prior art]
This type of dehumidifier includes a moisture absorber that moves repeatedly, a dehumidification fan that passes indoor air through the moisture absorber and then returns to the room to dehumidify the room, and heats air to pass moisture through the moisture absorber. A regeneration heater and a regeneration fan that repeat deprivation and regeneration in a circulation system, and a heat exchanger that separates moisture by exchanging heat with moisture-absorbing air in the middle of being passed through the moisture absorbent and returning to the regeneration heater side, BACKGROUND ART A body provided with a water receiver that receives water separated by a heat exchanger, and a water storage pump that sends water to a removable water storage tank to store water therein is known (for example, see Patent Document 1). ).
[0003]
This product uses a combination of a water receiver, a water storage pump, and a water storage tank to transfer water separated from moisture-absorbing air by the heat exchanger through a small, undisturbed water receiver near the heat exchanger, and to allow the water to flow down or flow naturally. The water is pumped into the water storage tank by the water storage pump while collecting and using the water, so that even if the water storage tank can be freely selected in accordance with the ease of installation and handling, the degree of freedom in design is high.
[0004]
The regeneration fan is located between the heat exchanger and the regeneration heater in the circulation system. As a result, the regeneration fan is located upstream of the regeneration heater, and the heated high-temperature air blown to the regeneration fan is passed through the desiccant to regenerate the desiccant efficiently. Further, since the regeneration fan sucks the low-temperature regeneration air cooled and dehumidified by the heat exchanger, there is an advantage that the regeneration fan is not affected by heat or moisture.

[0006]
[Problems to be solved by the invention]
However, in this type of dehumidifier, the dehumidification effect using a compressor, a condenser, and an evaporator and the dehumidification effect are still lower than those obtained by a dehumidifier. Therefore, the present inventors have conducted various experiments and studied with the aim of further improving the dehumidifying function. In such a process, the present inventor has noticed that dew condensation water has also adhered to the communication path from the heat exchanger to the regeneration fan. This is thought to be due to the temperature difference inside and outside the circulatory system at that part, but when dew water gradually accumulates at the lower part of the communication path, it tries to spread in the longitudinal direction of the communication path and enters the regeneration fan, It has been found that this may cause damage to the regeneration heater located downstream of the heater or decrease the dehumidification performance. Such dew condensation may occur in other parts of the circulation system than the heat exchanger, and dew condensation may occur due to a temperature difference inside the circulation system.
[0007]
An object of the present invention is to provide a dehumidifier capable of preventing dew water from entering a regeneration fan even when dew water is generated on the way out of a heat exchanger and returning again.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the dehumidifier of the present invention is a dehumidifier that repeatedly moves, a dehumidifying fan that returns indoors after passing indoor air through the desiccant, and dehumidifies the interior of the room. A regenerative heater and a regenerative fan that repeats heating and passing through the hygroscopic material to deprive and regenerate dehumidifying water in a circulating system, and a hygroscopic air that is passed through the hygroscopic material to deprive dehumidifying water and return to the regeneration heater side. A heat exchanger that separates dehumidified water by heat exchange, and a water receiver that receives the dehumidified water separated by the heat exchanger, provided in the main body, air after heat exchange in the circulation system exits the heat exchanger, It is characterized in that a collecting path is provided from a portion that may be generated or accumulated on the way to return to the water receiver and condensed water is collected.
[0009]
In such a configuration, the combination of a moisture absorbing material, a dehumidifying fan, a regeneration heater, a regeneration fan, and a heat exchanger repeatedly dehumidifies the indoor air with the moisture absorbing material in the circulation system, thereby absorbing moisture from the indoor air and dehumidifying. By repeating the process of removing the dehumidifying water by passing the heated air through the absorbent material, the regeneration is performed and the moisture absorption function for the indoor air is ensured, and the heat exchange in the heat exchanger from the absorbent air deprived of the dehumidifying water from the absorbent material. The dehumidification function can be satisfied with a smaller and lighter type than the type using a compressor by continuously separating the dehumidification water and receiving it in the water receiver.
[0010]
At this time, while the air after the heat exchange exits the heat exchanger and returns to the heat exchanger again through the regeneration heater and the regeneration fan, dew condensation water is generated due to a temperature difference inside and outside the circulation system and a temperature difference generated inside the circulation system. Even if there is a portion where water accumulates or accumulates, it is collected in a water receiver through a recovery pipe from this portion to the water receiver, and this reaches a portion other than the heat exchanger of the circulation system, impairing the dehumidifying function, and equipment. Can be prevented from being damaged.
[0011]
The dehumidifier of the present invention also has a dehumidifier that moves repeatedly, a dehumidifying fan that passes indoor air through the desiccant and then returns to the room to dehumidify the room, and heats air to pass through the desiccant. A regeneration heater and a regeneration fan that repeats dehumidifying water deprivation and regeneration in a circulation system and heat exchange with dehumidified air passing through the desiccant and depriving dehumidified water and returning to the regeneration heater side to separate dehumidified water. A heat exchanger and a water receiver for receiving dehumidified water separated by the heat exchanger are provided in the main body, and the regeneration fan is located between the heat exchanger and the regeneration heater in the circulation system, and the regeneration fan is connected to the regeneration fan. Another feature of the present invention is that a recess for receiving dew condensation formed on the inner surface of the connection passage and condensing at the lower portion thereof is provided in the communication path leading to the connection path, and the dew water received in the recess is collected in the water receiver.
[0012]
In such a configuration, the combination of a moisture absorbing material, a dehumidifying fan, a regeneration heater, a regeneration fan, and a heat exchanger repeatedly dehumidifies the indoor air with the moisture absorbing material in the circulation system, thereby absorbing moisture from the indoor air and dehumidifying. By repeating the process of removing the dehumidifying water by passing the heated air through the absorbent material, the regeneration is performed and the moisture absorption function for the indoor air is ensured, and the heat exchange in the heat exchanger from the absorbent air deprived of the dehumidifying water from the absorbent material. The dehumidification function can be satisfied with a smaller and lighter type than the type using a compressor by continuously separating the dehumidification water and receiving it in the water receiver.
[0013]
At this time, dew may condense on the inner surface of the communication path from the heat exchanger to the regeneration fan, and even if dew water collects at the lower part of the communication path, the dew water is received in the recess provided in the communication path. It can be prevented from accumulating in the flat lower part of the road and trying to spread in the longitudinal direction, and there is no inconvenience such as getting into the reproduction fan. In addition, since the condensed water received in the concave portion is collected in the water receiver, it is possible to prevent the condensed water in the concave portion from overflowing into the same state as in the conventional case having no concave portion. The recess has an advantage that the dehumidifier does not lose its function even if it is placed slightly inclined.
[0014]
In a further configuration in which the concave portion is formed in the duct forming the communication path, the concave portion can be provided without any special member, and the cost can be reduced accordingly.
[0015]
The recess is provided near the upstream side of the regeneration fan. In a further configuration,
If the condensed water that collects at the lower part of the access channel tries to spread to the regeneration fan, it can be received in the recess and prevented from reaching the regeneration fan any further. Even if dew water collects at the location, it can respond even if it tries to spread.
[0016]
In a further configuration, a storage chamber for condensed water is provided under the concave portion, and a collection conduit for guiding the condensed water from the storage chamber to the water receiver is provided.
While the recess has a flat surface area that can accept all the dew water that is going to reach the regeneration fan side, the recess is not shallow and bulky due to the storage room below it, and the dew water storage room below it Can be made small and not bulky in a plane, so that the amount of dew water to be received in the concave portion can be increased. In addition, although the dew water in the storage chamber can be guided to the water receiver by an optional route by the recovery pipe, the amount of storage increases, so that the recovery can be completed even if the recovery pipe is made thinner, so that the degree of freedom of piping is further increased. High and easy to set.
[0017]
In a further configuration, the heat exchanger causes the moisture-absorbing air to exchange heat with room air sucked by the dehumidifying fan.
A heat exchanger that exchanges heat with the indoor air sucked by the dehumidifying fan is limited by the size of the heat exchanger to completely cool the absorbed air like an evaporator using a compressor. Although condensation easily forms on the communication path from the fan to the regenerating fan, dew condensation water easily accumulates.
[0018]
Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be employed alone or in combination in various combinations as much as possible.
[0019]
【Example】
Hereinafter, a dehumidifier according to the present invention will be described in detail with reference to FIGS. 1 to 11 to provide an understanding of the present invention. The following description shows specific examples of the present invention, and does not limit the content of the claims.
[0020]
As shown in FIG. 1 and FIG. 2 in the present embodiment, the dehumidifier of the present embodiment is configured such that the hygroscopic material 1 that moves repeatedly and the indoor air 2 are passed through the hygroscopic material 1 and then returned to the room to be indoors. A dehumidifying fan 3 for performing dehumidification, a regenerating heater 5 and a regenerating fan 6 for repeating in a circulating system A heating a regenerating air 4 and passing the dehumidifying water through the dehumidifying material 1 for regenerating. A heat exchanger 7 for exchanging heat with the regenerated air 4 for absorption on the way to return to the regeneration heater 5 to remove the dehumidification water and pass through the heat exchanger 7 to separate the dehumidification water; A receiving water receiver 8.
[0021]
In such a dehumidifier, the circulation system A repeats dehumidification of the room air 2 with the moisture absorbent 1 by a combination of the moisture absorbent 1, the dehumidifying fan 3, the regeneration heater 5, the regeneration fan 6, and the heat exchanger 7. . At this time, the dehumidifying water is deprived by passing the heated regenerated air 4 through the hygroscopic material 1 which repeats the dehumidification by absorbing moisture from the indoor air 2 to regenerate the dehumidified water, thereby guaranteeing the hygroscopic function for the indoor air 2. The dehumidified water 4a from which the dehumidified water has been taken away is separated by heat exchange in the heat exchanger 7 and returned to the regenerated air 4, and the separated water continues to be received in the water receiver 8. This makes it possible to satisfy the dehumidifying function with a smaller and lighter than the type using a compressor.
[0022]
In particular, in the present embodiment, the regeneration fan 6 is located between the heat exchanger 7 and the regeneration heater 5 in the circulation system A as shown in FIGS. The channel 101 is provided with a concave portion 102 as shown in FIG. 8 for receiving the dew water condensed on the inner surface of the communication channel 101 and collected at the lower portion, and the dew water received in the concave portion 102 is collected in the water receiver 8. .
[0023]
As a result, during the dehumidifying operation as described above, dew may condense on the inner surface of the communication path 101 from the heat exchanger 7 to the regeneration fan 6. Since the water is received in the concave portion 102 provided in the communication path 101, it is possible to prevent the water from accumulating in the flat lower portion of the communication path 101 and trying to spread in the longitudinal direction. Therefore, the inconvenience that dew water enters the regeneration fan 6 does not occur. In addition, since the dew water received in the concave portion 102 is collected in the water receiver 8, it is possible to prevent the dew water in the concave portion 102 from overflowing and to be in the same state as the conventional case without the concave portion 102. Such a concave portion 102 has an advantage that the function is not lost even when the dehumidifier is placed slightly inclined.
[0024]
Such a concave portion 102 is preferably provided at the lower part of the communication path 101, particularly at the lowest position, as shown in the figure. However, the lowermost portion changes depending on the cross-sectional shape of the communication path 101, the shape in the axial direction, the presence or absence of the inclination, and the like. In the example illustrated in FIGS. 1 to 8 and the example illustrated in FIG. 9, the concave portion 102 is provided at the lowermost portion in the circumferential direction of the communication path 101 and near the upstream side of the reproduction fan 6. In such a position near the regeneration fan 6, even if dew condensation collected at the lower part of the communication path 101 tries to spread to the regeneration fan 6 side, it is received in the concave portion 102, and furthermore, the condensed water is further moved to the regeneration fan 6 side. Can be prevented from spreading. Therefore, no matter where the dew condensation water collects at the lower portion of the communication path 101, it is possible to cope with the expansion of the dew condensation water.
[0025]
If such a concave portion 102 is provided, for example, if it is formed in the duct 103 forming the communication path 101, the concave portion 102 can be provided without any special member, and the cost can be reduced accordingly. However, in this case, the duct 103 is a cylindrical member, and the die-cutting structure when the die is molded is complicated by the concave portion 102. Therefore, in the examples shown in FIGS. 1 to 8, the upstream half 102a is formed integrally with the duct 103, the remaining downstream half 102b is formed separately, and the half 102b is combined with the half 102a. Like that. In this way, the upstream half 102a integrally formed with the duct 103 has a form opened toward the downstream end of the duct 103, so that the portion forming the upstream half 102a of the mold is the axis of the duct 103. Can be simply stamped out in the downstream direction. Since the remaining downstream half 102b is a single piece, there is no problem of die cutting.
[0026]
In the example shown in FIGS. 1 to 8, a dew condensation water storage chamber 104 as shown in FIGS. 1, 2, 3, and 8 is further provided below the recess 102, and the dew water is discharged from the storage chamber 104. A recovery conduit 105 leading to the water receiver 8 is provided. Accordingly, the concave portion 102 has a flat surface size capable of receiving the dew condensation water that is going to reach the regeneration fan 6 side, and the concave portion 102 is not shallow due to the presence of the storage chamber 104 thereunder. Can be. At the same time, the condensed water storage chamber 104 under the condensed water can be made small and not bulky in a plan view to increase the amount of dew water stored in the recess 102. In addition, the dew condensation water in the storage chamber 104 can be guided to the water receiver 8 by an arbitrary route by the recovery pipe 105. However, the large amount of storage causes the recovery pipe 105 not to be bulky and to have a thinner bending degree. However, since the collection can be made in time, the degree of freedom of the piping is further increased and it is easy to provide.
[0027]
In order to provide such a deep storage chamber 104 below the concave portion 102, the portion of the storage chamber 104 is formed by dividing the concave portion 102 into an upstream half portion 102a and a downstream half portion 102b. 8 can also be divided into an upstream portion 104a and a downstream portion 104b, and easily divided into an upstream portion 102a and a downstream portion 102b of the recess 102 as shown in FIG. Thereby, it is possible to form the mold easily and at low cost as compared with the case where the die-cutting structure is complicated and integrally molded.
[0028]
The connection port 104c of the storage chamber 104 with the recovery pipe 105 is formed integrally with the downstream portion 104b, which is the side on which molding is easy, in a cylindrical shape, and the recovery pipe 105 is connected to this connection port 104c.
[0029]
Further, in the example shown in FIG. 8, the suction port 6c of the reproduction fan 6 is fitted inside the rear end of the communication path 101, and a step 111 is formed on the side of the recess 102 on the reproduction fan 6 side. The step portion 111 functions as a weir and collects at the lower part of the communication path 101 to block the dew condensation water that is going to spread to the regeneration fan 6 side. It is easier to prevent.
[0030]
However, the lower part of the communication path 101 is added to the concave part 102 in the circumferential direction and also in the longitudinal direction toward the concave part 102 so that dew condensation water collected at the lower part of the communication path 101 can be guided to the concave part 102. You can also.
[0031]
In another example of the concave portion 102 shown in FIG. 9, the concave portion 102 reaches the discharge port 7d of the heat exchanger 7 in a flush state as shown in the figure. As a result, even if the condensed water received in the recess 102 accumulates and tries to spread in the longitudinal direction of the communication path 101, the water does not spread to the regeneration fan 6 side, so that it only spreads to the heat exchanger 7 side. Can be regulated. As a result, the condensed water received in the concave portion 102 can be returned to the heat exchanger 7 and received by the water receiver 8 to be collected. Therefore, in this case, no special recovery pipe is required, and there is no fear of overflow.
[0032]
In another example shown in FIG. 10, the concave portion is omitted, and the lower wall of the communication path 101 has a downward slope toward the heat exchanger, so that dew condensation water collected at the lower part of the communication path 101 flows toward the heat exchanger. It is made to run down. Such an inclination can be formed only at the lower portion of the communication path 101, or by the entire inclination, a tapered shape, or the like. In the case of the tapered shape, the dew water condensing on the upper side of the communication path 101 tends to be transmitted to the regeneration fan 6 side. Therefore, a drooping wall is provided at the rear end to block the dripping wall and drip it on the inclined lower part. It is preferred to regulate to.
[0033]
The heat exchanger 7 of the dehumidifier of the example shown in FIGS. 1 to 8 exchanges heat with the indoor air 2 sucked by the dehumidifying fan 3 as shown by broken lines in FIGS. For this reason, the heat exchanger 7 connects a plurality of heat exchange elements 7b having a plurality of branch air passages 7a, for example, in parallel in the middle as shown in FIGS. 2 and 3, and introduces the hygroscopic air 4a. Heat is exchanged with the room air 2 passing outside the branch air passage 7a. Although the heat exchange element 7b is a blow-molded product made of resin, heat exchange can be achieved because the wall thickness is thin. However, since it is heat exchange with the indoor air 2, there is a limit in cooling the moisture-absorbing air like an evaporator using a compressor due to its size and the like. Condensation water easily accumulates on the connecting path 101 leading to the condensed water. Although the communication path 101 is provided with the regenerative heater 5 in the heat exchanger 7 although the hygroscopic material 1 is interposed therebetween, and is connected at a relatively close position in the circulation system A, the internal temperature increases. Can easily lead to condensation. However, it is possible to sufficiently cope with the above-described dew condensation water recovery structure and its operation.
[0034]
The dehumidifier of the example shown in FIGS. 1 to 8 will be described in further detail. A detachable water storage tank as shown in FIG. 2 for storing dehumidified water and dew condensation water collected in a water receiver 8 as shown in FIG. 9 and a water storage pump 11 as shown in FIG. 6 for sending dehumidified water or dewed water of the water receiver 8 to the water storage tank 9 and storing the water. The circulatory system A including the combination of the moisture absorbent 1, the dehumidifying fan 3, the regeneration heater 5, the regeneration fan 6, and the heat exchanger 7, the water receiver 8, and the water storage pump are shown in, for example, FIGS. It is provided as an internal device 16 or the like, and the water storage tank 9 is detachably attached to the main body 12.
[0035]
As a result, while exhibiting a dehumidifying function in the circulation system A provided on the main body 12 side, dehumidified water separated from the regenerated air 4 that has absorbed moisture after regenerating the absorbent material 1 and dew condensation water in the communication path 101 are: Similarly, by receiving the water with the water receiver 8 provided on the main body 12 side, the water is supplied to the water storage tank 9 and stored by the water storage pump 11 without being spread over a wide area, thereby minimizing the required space of the main body 12 and avoiding the fullness. Thus, it is possible to prevent the inconvenience that the separated dehumidified water evaporates and escapes and humidifies the room instead of allowing the dehumidified water to separate for a long time. The water supply channel 26 as shown in FIGS. 2 and 6 from the water storage pump 11 to the water storage tank 9 may be configured in any manner and connected in any way, but flowing from the upper part of the water storage tank 9 causes a reverse flow. It is preferred because there is no However, if a check valve is provided in the middle of the water supply passage 26 or at a portion where the water supply passage 26 of the water storage tank 9 is detachably connected, the problem due to the backflow can be solved. Further, the condensed water accumulated in the concave portion 102 can be sent to the water receiver 8 and the water storage tank 9 by the water storage pump 11 or a dedicated pump (not shown).
[0036]
In particular, the water storage tank 9 is provided on the upper front side of the main body 12. In this manner, since the water storage tank 9 is located on the front side of the upper portion of the main body 12 as shown in FIG. 1, the water storage tank 9 receives and sends the dehumidified water collected in the water receiver 8 as described above. Can be made to appear from around the front of the user. In other words, dehumidifying water is generated by dehumidifying the indoor air 2, and the user can confirm that the dehumidified water is stored in the water storage tank 9, so that the user can feel the dehumidification and can easily evaluate the dehumidification. Moreover, by making the shape and size of the water storage tank 9 provided in the main body 12 correspond to the surplus space due to the arrangement of the devices on the main body 12 side, the water storage tank 9 can be formed without wasteful space or unnatural dents or protrusions. Can be provided. At the same time, since the water storage tank 9 is located outside the main body 12 and at the side closest to the user and for easy attachment / detachment for draining or cleaning the water storage tank 9, The water storage tank 9 can be easily handled independently.
[0037]
However, even if the water storage tank 9 is colorless or colored, transparent, translucent, or opaque such as milky white, the internal water storage and the shadow of that level can be reflected on the external surface and can be confirmed from the outside, or even partially. It is sufficient if there is a water storage inspection unit that can confirm such water storage and its level. Such a water storage tank 9 and its parts are obtained by glass or synthetic resin, but are preferably made of synthetic resin in terms of lightness and breakability. The main body 12 is equipped with a variety of devices as described above, and may be entirely or partially made of metal from the viewpoint of durability and heat resistance, but is not limited to this, and is not limited thereto. Alternatively, the whole can be made of a synthetic resin. In addition, even if it is made of a synthetic resin, heat resistance can be obtained as required by a heat-resistant resin material.
[0038]
Also, as shown in FIG. 1, below the water storage tank 9 of the main body 12, that is, under the installation portion where the water storage tank 9 is provided, in the example shown, under the step portion 15 as shown in FIG. , The heat exchanger 7, the rotating absorbent material 1 is located, the regeneration heater 5 and the regeneration fan 6 are located above and below the absorbent material 1, and the regeneration air 4 is supplied from the regeneration fan 6 to the regeneration heater 5, The circulation system A returns to the regeneration fan 6 after the moisture absorbent 1 and the heat exchanger 7 are sequentially reached. Behind the regeneration heater 5 and the regeneration fan 6, the dehumidifying fan 3 opens its intake port 3a toward the intake port 22 on the front surface of the main body 12 through the hygroscopic material 1, and connects the blow port 3d to the exhaust port 23 on the upper part of the main body 12. It is located so as to be connected to.
[0039]
The water receiver 8 has a lid 8a as shown in FIGS. 2 and 6, and dehumidified water or dew water separated from the hygroscopic air 4a by the heat exchanger 7 is received through a water passage 8b of the lid 8a. Further, the recovery conduit 105 from the recess 102 is also connected to the lid 8 a so that the dew condensation water from the recess 102 is received by the water receiver 8. As shown in FIGS. 3 and 6, the water storage pump 11 is provided in the middle of the base side of the water passage 26 extending from the bottom of the water receiver 8 to the water storage tank 9. Further, in the illustrated example, a filter 93 as shown in FIGS. 1 and 2 is provided inside the intake port 22. As shown in FIGS. 1 and 2, the hygroscopic material 1 is provided with a gear 1c in a case 1b containing and holding a hygroscopic agent 1a such as zeolite, and is directly connected to the geared motor 71 as shown in FIGS. The pinion gear 72 is engaged with the pinion gear 72 to rotate at a predetermined speed.
[0040]
With the arrangement of the internal devices 16 as described above, the moisture absorbent 1 rotates and repeatedly dehumidifies the indoor air 2 and regenerates it thereafter, so that the room air 2 for dehumidification and regeneration passes in the passing direction shown in FIG. It can be a flat one with a good thickness, and it is located on the lower side using the flat space of the water storage tank 9 provided on the front side of the upper part of the main body 12 together with the heat exchanger 7 located on the front side, Can be installed without wasted space. The upper water storage tank 9, the lower heat exchanger 7 and the moisture absorbent 1, and the regenerative heater 5 and regenerative fan 6 located behind the recirculation tank 9 without wasteful dispersion. While the system A is compactly configured as shown in FIGS. 1 and 2 together with the main body 12 for accommodating the system A, as shown in FIG. The dehumidifying fan 3 having a sufficient size is provided without particularly increasing the size of the main body 12 to secure a sufficient air volume, a low-speed intake and a low-speed air blow that are quiet and do not allow a human to feel the wind, and are high. It can exhibit a dehumidifying function. However, for wide-area dehumidification, it is necessary that at least one of the intake air and the air blow satisfies a condition that extends to a required range of dehumidification.
[0041]
As shown in FIGS. 1 and 2, the inside of the main body 12 is partitioned by a partition wall 75 made of a synthetic resin into a rear portion containing the dehumidifying fan 3 and a front portion containing the circulation system A. The partition wall 75 has a dehumidifying motor 3e attached to the rear side of the main body, and forms an air inlet 3a therearound. The dehumidifying impeller 3b, which is directly connected to the dehumidifying motor 3e, is located on the rear side, and is covered with a synthetic resin cover wall 3c attached to the partition wall 75 to constitute the dehumidifying fan 3. Further, on the front side of the main body 12, a partition wall made of a synthetic resin as shown in FIGS. 1, 2, 3, 4, and 5 for further partitioning the moisture absorbent 1 side and the heat exchanger 7 side. 77 are provided. The partition wall 77 supports the hygroscopic material 1 at the center thereof so as to be rotatable by a shaft portion 77a shown in FIGS. 1 and 2, and the geared motor 71 is attached so that the hygroscopic material 1 is driven to rotate on the partition wall 77. ing.
[0042]
In addition to the dehumidifying motor 3e, the regeneration heater 5 and the regeneration fan 6 are located between the partition walls 75 and 77. The regenerating heater 5 is held in an inflow port 73a at the rear of the heating unit cover 73 attached to the partition wall 77 as shown in FIG. 2, and the heating unit cover 73 spreads in a trumpet shape up, down, left and right toward the front side. The outlet 73b formed in this manner is opposed to a range in which the moisture absorbent 1 is to be regenerated with a suitable gap S as shown in FIG. The above-mentioned wrapper shape of the heating unit cover 73 is such that after achieving efficient contact between the regeneration heater 5 and the regeneration air 4 and heating by the small inlet port 73a, the regeneration air 4 which has been sufficiently heated is heated. As much as possible, the regeneration air 4 from the regeneration fan 6 is blown to the rear area of the heating section cover 73 over a wider area of the moisture absorbent 1 so that efficient regeneration can be achieved. At the rear of the heating unit cover 73, a regeneration cover 74 as shown in FIG. 1, FIG. 2, FIG. 3, and FIG. It is attached to a partition wall 77 together with 73. As shown in FIG. 2, the regenerating cover 74 blows the regenerating air 4 to the regenerating heater 5 in a state in which the regenerating air 4 covers the entire heating unit cover 73. It is also a heat cover.
[0043]
The regenerative fan 6 fits the suction port 6c of the casing 6b accommodating the impeller 6a to the rear end of the duct 103 of the communication path 101 formed integrally with the partition wall 77 as shown in FIGS. The outlet 6d of the casing 6b is connected to the air guide port 74a of the regeneration cover 74 as shown in FIGS. 2, 3, and 4.
[0044]
Here, the path from the regeneration fan 6 to the regeneration heater 5, for example, the regeneration cover 74 has an inclined portion 74d whose lower portion is directed to the lower portion 74c as shown in FIGS. Even if condensed water is generated or invades, it is guided to the lower portion 74c to prevent the condensed water from circulating through the circulating system A, reducing the dehumidifying efficiency or affecting other things. Can be prevented. When the amount of dew water is extremely small, the water can be dried and diverged on the way to or from the lower portion 74c. However, when the amount gradually increases, the water can be collected from the lower portion 74c to the water receiver 8 through a collection pipe 112 as shown in FIGS.
[0045]
In the circulatory system A, the low-level portion 74c due to the inclined shape of the concave portion 102 and the regenerating cover 74, and the collecting portion of the condensed water, other than necessary portions, do not provide a place where the condensed water accumulates or flows, It is possible to prevent the dew condensation water from flowing to an inadvertent portion or accumulating therein and affecting other portions.
[0046]
By the way, the regenerated air 4 after the heat exchange in the circulation system A exits from the heat exchanger 7 and returns again through the regeneration heater 5 and the regeneration fan 6, that is, the temperature inside and outside the circulation system A even in a part other than the heat exchanger 7. It is conceivable that dew condensation water is generated or accumulated due to a difference, an internal temperature difference, or for some reason. Therefore, it is preferable to provide a recovery pipe 112 extending from such a portion or a pool portion subsequent thereto to the water receiver 8 for recovery. The collecting path including such a pool portion and the collecting pipe 112 can be formed in any manner.
[0047]
As shown in FIGS. 1 and 2, the partition wall 77 further opens a portion corresponding to the moisture absorbent 1 to the front side to allow the room air 2 sucked by the regeneration fan 6 to flow through the moisture absorbent 1.

The receiving chamber 79 receives the hygroscopic air 4a with its rear end opposed to the hygroscopic material 1 with a gap S as shown in FIG. 11, and has a connection port 80 with the inlet 7 c of the heat exchanger 7 at the front. The provided and received moisture-absorbing air 4 a is sent to the heat exchanger 7. The outlet 7d of the heat exchanger 7 shown in FIG. 1 is connected to the front end of a duct 103 forming a communication path 101 as shown in FIG. 1, and the moisture-absorbed air 4a is dehumidified by heat exchange with the room air 2 to be regenerated. The regenerated air 4 is sucked by the regenerating fan 6 and is again used for regenerating the hygroscopic material 1.
[0048]
An operation surface 28 shown in FIG. 2 and an exhaust port 23 from the dehumidifying fan 3 are provided side by side on the rear upper surface of the main body 12. The air outlet 23 has a rectangular opening 23a formed on the upper surface of the main body 12 and an opening 23b formed on the rear surface of the main body 12 in a continuous state. A cover 65 is provided, and is driven by an actuator such as a motor (not shown) so that the wind direction set on the operation surface 28 is obtained. The wind direction is set, for example, in a substantially vertical fully closed state, each intermediate open state between the fully closed state and the fully open state shown in FIG. 2, and a continuous wind direction that continuously reciprocates between the fully closed state and the fully open state. There is a change state. In the fully closed state, only the opening 23b is opened rearward, and the air is blown backward. In the fully opened state, the entire area of the opening 23a is opened, and the air is blown right above. In each intermediate opening state, the air is blown in a direction along the opening angle of the wind direction setting lid 65.
[0049]
As shown in FIG. 2, the main body 12 is further provided with casters 33 on both left and right sides of a corner that is diagonally located with respect to the water storage tank 9 when viewed from the side of the main body 12. Accordingly, when the main body 12 is grounded by the pair of left and right casters 33 and pulled around, when the main body 12 is tilted backward to the side where the diagonal line is vertical, the center of gravity of the main body 12 including the water storage tank 9 is placed on the casters 33. Even if the position of the center of gravity is different at different times due to the difference in the amount of water stored in the water storage tank 9, the weight can be balanced back and forth by adjusting the tilting angle of the body 12 to the rear side without difficulty. It can be moved and is convenient when it is used in a different room, such as the same room, between rooms, or between a room and a bathroom. In the bathroom, it can be used not only for dehumidification and drying itself, but also for drying laundry.
[0050]
In addition, a seat leg 35 is provided at the bottom of the main body 12 as an example of a seat portion to be grounded in a use state. As shown in FIG. 2, the caster 33 is slightly lifted from an installation surface 36 so that the main body 12 is installed. It is. Accordingly, when the main body 12 is installed in the use state, the casters 33 are not grounded, and the installation state of the main body 12 is not made unstable.
[0051]
Along with the provision of the casters 33, a pull 37 is provided on the back of the main body 12, as shown in FIGS. The puller 37 in the illustrated example has a pair of left and right pull rods 37a held so as to be able to be taken in and out of a sheath 39 provided vertically at the center of the back of the main body 12 in the left and right direction. It is composed of the attached grip 37b. Such a pull 37 can be easily and freely moved by sharing the support of the main body 12, the angle adjustment, and the wiring when the main body 12 is tilted rearward as described above and turned around. In addition, it is preferable to provide a hand-held handle pivotally supported so that it can be raised and lowered (not shown) at the upper part of the water storage tank 9.
[0052]
The gap S between the heating unit cover 74 and the receiving chamber 79 shown in FIG. 11 and the hygroscopic material 1 is for preventing the hygroscopic material 1 from interfering with others even when the hygroscopic material 1 is driven to rotate. However, the gap S also serves as a gap S in which the regeneration air 4 and the moisture-absorbing air 4a are mixed, which causes a reduction in dehumidifying efficiency. Therefore, in the present embodiment, a PTC heater which is a semiconductor heater is employed as the regenerative heater 5, and the heating unit cover 73 and the receiving chamber 79 are utilized by utilizing the fact that the PTC heater does not reach a high temperature of about 200 ° C. at maximum, unlike the ribbon heater. And the case 1b of the hygroscopic material 1 are made of synthetic resin, and a minimum gap S1 at which they do not come into contact with each other due to their thermal expansion and molding errors is secured, and the mixing of the regeneration air 4 and the hygroscopic air 4a is minimized. So that it can be held down. In particular, the gap S1 between the heating unit cover 73 and the case 1b is formed between the hygroscopic material receiving flange 1e of the case 1b and the convex portion 73f of the heating unit cover 73 which is fitted to the inner periphery thereof, and the rear end surface of the flange 1e. Between the rear end face and the front end face of the heating section cover 73 which faces the outer periphery of the convex portion 73f, and is formed as a hook-shaped cross section having a so-called labyrinth gap S1. And regeneration air are more easily prevented from mixing. A gap S1 between the receiving chamber 79 and the case 1b of the absorbent material 1 is formed straight between the rear end of the receiving chamber 79 and the holding member 121 attached to the case 1b. However, a labyrinth gap may be provided in this portion as well.

【The invention's effect】
ADVANTAGE OF THE INVENTION According to the dehumidifier of this invention, the dehumidification of indoor air is repeated by a circulatory system by the combination of a hygroscopic material, a dehumidifying fan, a regeneration heater, a regeneration fan, and a heat exchanger in a circulatory system. The dehumidifying water is removed from the hygroscopic air by removing the dehumidifying water by passing the heated air through the heated hygroscopic material to repeat the dehumidifying and ensuring the function of absorbing the dehumidifying water with respect to the indoor air. The dehumidification function can be satisfied with a smaller and lighter type than the type using a compressor by continuously separating the dehumidification water by the heat exchange and receiving the dehumidification water in the water receiver.
[0054]
At this time, while the air after the heat exchange exits the heat exchanger and returns to the heat exchanger again through the regeneration heater and the regeneration fan, dew condensation water is generated due to a temperature difference inside and outside the circulation system and a temperature difference generated inside the circulation system. Even if there is a portion where water accumulates or accumulates, it is collected in a water receiver through a recovery pipe from this portion to the water receiver, and this reaches a portion other than the heat exchanger of the circulation system, impairing the dehumidifying function, and equipment. Can be prevented from being damaged.
[0055]
According to the dehumidifier of another feature of the present invention, the combination of a moisture absorbent, a dehumidifying fan, a regeneration heater, a regeneration fan, and a heat exchanger, repeatedly dehumidifying the indoor air with the moisture absorbent in the circulation system, Dehumidifying water is repeatedly absorbed by absorbing moisture from indoor air. Dehumidifying water is removed by passing heated air through the heated air. The dehumidifying water can be separated by the heat exchange in the exchanger and continuously received in the water receiver, and the dehumidifying function can be satisfied with a smaller and lighter type than the type using the compressor.
[0056]
At this time, dew may condense on the inner surface of the communication path from the heat exchanger to the regeneration fan, and even if dew water collects at the lower part of the communication path, the dew water is received in the recess provided in the communication path. It can be prevented from accumulating in the flat lower part of the road and trying to spread in the longitudinal direction, and there is no inconvenience such as getting into the reproduction fan. In addition, since the condensed water received in the concave portion is collected in the water receiver, it is possible to prevent the condensed water in the concave portion from overflowing into the same state as in the conventional case having no concave portion. The recess has an advantage that the dehumidifier does not lose its function even if it is placed slightly inclined.
[0057]
According to a further configuration in which the concave portion is formed in the duct forming the communication path, the concave portion can be provided without any special member, and the cost can be reduced accordingly.
[0058]
According to a further configuration in which the concave portion is provided near the upstream side of the regeneration fan, even if the condensed water that collects at the lower portion of the communication path attempts to spread to the regeneration fan side, it is received in the concave portion, and furthermore, the condensed water is further reduced. It can be prevented from spreading to the side, so that no matter where the condensation water collects at the lower part of the connection path, even if it tries to spread, it can cope with it.
[0059]
A condensed water storage chamber is provided below the recess, and a collection conduit for guiding the condensed water from the storage chamber to the water receiver is provided. According to a further configuration, the condensed water trying to reach the regeneration fan is left. The recess shall not be so shallow by the presence of the storage chamber below it, and the storage chamber of the condensed water beneath shall be small and not bulky, and The amount of condensed water to be received can be increased. In addition, although the dew water in the storage chamber can be guided to the water receiver by an optional route by the recovery pipe, the amount of storage increases, so that the recovery can be completed even if the recovery pipe is made thinner, so that the degree of freedom of piping is further increased. High and easy to set.
