Description

【０００１】
【発明の属する技術分野】
本発明は、主に一般家庭において部屋の除湿、室内に干された洗濯物の乾燥等に用いられる回転式吸着材（除湿ローター）を備えた吸着式の除湿装置並びに除湿装置の結露水処理方法に関するものである。
【０００２】
【従来の技術】
近年、主に一般家庭で使用される回転式吸着材（除湿ローター）を備えた吸着式の除湿装置においては、再生に用いる空気を循環させて高露点状態にし、その高露点状態の空気を室内空気で冷却して凝縮させ結露水として回収することにより除湿を行うものが一般的であった（例えば、特許文献１参照）。
【０００３】
以下、吸着材で室内から吸湿して結露水として回収する吸着式の除湿装置の構成及び動作について図９を参照しながら説明する。
【０００４】
図９は従来の再生に用いる空気を循環させて結露水として回収する除湿装置の構成を示す簡易的な断面図であり、図９に示すように、除湿装置の本体１０１に、室内空気の吸込口１０２と吹出口１０３を開口し、本体１０１内には吸湿部１０４において室内空気から吸湿し、再生部１０５では加熱手段１０６により加熱されて脱湿し再生する吸着材１０７と、吸湿部１０４と再生部１０５が連続的に入れ替わるように吸着材１０７を回転させる駆動手段１０８と、吸込口１０２から室内空気を吸い込んで吸湿部１０４に供給した後、吹出口１０３から室内に吹出す処理ファン１０９と、加熱手段１０６を介して再生部１０５に高温の再生空気を供給する再生ファン１１０と、再生部１０５において吸着材１０７の脱湿分を含んだ再生空気を処理ファン１０９により供給される室内空気によって冷却する凝縮器１１１とを備えており、凝縮器１１１で冷却された再生空気を再生部１０５に戻して循環させる循環風路１１２を形成している。
【０００５】
以上のように構成された除湿装置の動作について説明すると、室内空気は処理ファン１０９によって吸込口１０２から吸い込まれ、凝縮器１１１に供給されて高湿の再生空気を冷却して吸湿部１０４に供給される。吸湿部１０４において室内空気は吸着材１０７に吸湿されて乾燥空気となり、吹出口１０３から室内に吹出す。一方、再生ファン１１０により創出させる再生空気は加熱手段１０６で加熱されて高温となり再生部１０５に供給される。再生部１０５において吸着材１０７から脱湿する水分を含んで高湿となった後、凝縮器１１１において室内空気によって露点温度以下に冷却されて再生ファン１１０に吸い込まれ循環する。この循環により再生空気は室内空気の温度より高い露点を維持して凝縮器１１１での結露を促進する。凝縮器１１１で露点温度以下に冷却された再生空気中の水分は結露水となって水抜き穴１１３から外部に排水され、この排水された結露水の量が除湿装置の除湿量になる。なお、吸着材１０７の吸湿量には限界があるので、駆動手段１０８によって吸着材１０７を回転移動させ、吸湿部１０４における吸湿と再生部１０５における脱湿再生を連続的に入れ替え繰り返し実行することにより、長時間の連続した除湿を可能にしている。

【０００７】
【発明が解決しようとする課題】
以上の例のように、再生に用いる空気を循環させて高露点状態を維持し、室内空気により冷却して結露水として回収することにより除湿を行う技術が開示されているが、この高露点状態の再生空気は循環風路１１２内の凝縮器１１１以外の部分で特に飽和蒸気となる再生ファン１１０においては外部の雰囲気により冷却されて結露し易く、結露が進むと再生ファン１１０内部に結露水として滞留して送風量を低下させるという問題点があった。そして、この滞留した結露水を処理するには再生ファン１１０にホースを接続して排水する等の大掛かりな対策が必要であった。
【０００８】
本発明は上記課題を解決するものであり、再生ファン１１０内での結露を抑制するとともに、循環風路１１２内の凝縮器１１１以外の部分、特に再生ファン１１０内部に滞留する結露水を確実に且つ簡易的に処理して所定の再生風量を維持できる除湿装置並びに除湿装置の結露水処理方法を提供することを目的としている。
【０００９】
【課題を解決するための手段】
本発明の除湿装置は上記目的を達成するために、再生ファンに発生した結露水を集水する集水手段と、集水した結露水をケーシング外部に排水する排水溝と、排水溝から排水される結露水を貯留して吸着材の吸湿部の回転軸近傍の加熱手段に対向する面に接触させる貯水部とを再生ファンのケーシングに形成して、貯水部と吸着材の間隔を貯水部に溜まった結露水が吸着材に接触可能な寸法に規定することとしている。そして、再生ファンに発生した結露水を集水手段で集水し、排水溝を通じてケーシング外部に排水し、排水した結露水を貯水部で貯留して成長させ、成長した結露水を吸着材に接触させて浸潤させ、結露水が浸潤した吸着材を再生部において加熱して脱湿し、脱湿した水分を凝縮器において冷却して結露水として回収することにより簡易的に処理することができる。また、貯水部から滑落した結露水を貯水部の下方に吸着材に向けて付設した弾性体によって受け止め、吸着材に再接触させて確実に処理することができる。
【００１０】
また、他の手段は、吸湿部において発生する吸着熱を再生ファン内部に伝達するようにケーシングの吸着材に対向する面を熱伝導の良い金属部材で形成し、更に伝熱面積の増加と再生空気の撹拌を行うため金属部材及び金属部材の逆面に複数の凸部及び突起部を形成することとしている。そして、吸着熱をケーシング内部の再生空気に効率良く伝達し温度を上昇させて再生ファン内での結露を抑制することができる。
【００１１】
【発明の実施の形態】
本発明は、除湿装置の本体内に、吸湿部において室内空気より吸湿し、再生部では加熱手段により加熱されて脱湿し再生する吸着材と、吸湿部と再生部が入れ替わるように吸着材を回転させる駆動手段と、吸湿部に室内空気を供給する処理ファンと、加熱手段を介して再生部に高温の再生空気を供給する再生ファンを備え、吸着材からの脱湿分を再生空気に混合して凝縮器に導入し、処理ファンにより供給される室内空気を用いて冷却して結露水として回収し、冷却されて飽和した再生空気を再生部に戻す循環風路を形成して再生空気を高露点状態に維持し、循環風路内に滞留する結露水を吸着材に浸潤させるようにしている。そして、結露水が湿潤した吸着材を駆動手段によって再生部に回転移動し、再生部において加熱手段で加熱して湿潤した水分を脱湿し、脱湿した水分を再生空気に混合して凝縮器に導入し、凝縮器において室内空気によって冷却して再度凝縮させて結露水として回収することによって簡易的に処理を行うものである。
【００１２】
また、循環風路内に滞留した結露水を集水し、集水した結露水を吸着材に接触させ、接触時の水滴の表面張力を利用して円滑に湿潤させるものである。
【００１３】
また、再生部において加熱手段に対向する吸着材表面に結露水を接触させ、加熱手段近傍において十分に乾燥した吸着材表面を活用して確実に結露水を湿潤させるものである。
【００１４】
また、吸湿部に位置する吸着材に結露水を接触させて、吸着材が吸湿部から再生部に回転移動する間に接触した結露水を十分に湿潤させて拡散し、再生部における脱湿を容易にするものである。
【００１５】
また、結露水を吸着材の回転軸近傍に接触させ、室内空気の吸湿に用いる吸着材の領域を確保して除湿性能への影響を抑制するものである。
【００１６】
また、本発明は、除湿装置の本体内に吸湿部において室内空気より吸湿し、再生部では加熱手段により加熱されて脱湿し再生する吸着材と、吸湿部と再生部が入れ替わるように吸着材を回転させる駆動手段と、吸湿部に室内空気を供給する処理ファンと、加熱手段を介して再生部に高温の再生空気を供給する再生ファンを備え、吸着材からの脱湿分を再生空気に混合して凝縮器に導入し、処理ファンにより供給される室内空気を用いて冷却して結露水として回収し、冷却されて飽和した再生空気を再生部に戻す循環風路を形成して再生空気を高露点状態に維持し、再生ファンの外郭を形成するケーシングに循環風路内に滞留する結露水を集水する集水手段と集水した結露水を吸着材に接触させる接触手段を形成している。そして、再生ファン内に結露して滞留した結露水を集水手段で集水し、集水した結露水を接触手段において吸着材に接触させて湿潤させ、結露水が湿潤した吸着材を駆動手段によって再生部に回転移動し、再生部において加熱手段で加熱して湿潤した水分を脱湿し、脱湿した水分を再生空気に混合して凝縮器に導入し、凝縮器において室内空気によって冷却して再度凝縮させて結露水として回収することによって簡易的に処理を行うものである。
【００１７】
また、ケーシングの内面下方に水受け部を設け、この水受け部の最下点に向けて下り勾配を形成して、ケーシング内面に結露した結露水をその自重を利用して水受け部に滴下させ、水受け部に形成した下り勾配によって最下点に導いて容易に集水を行うものである。
【００１８】
また、水受け部の最下点とケーシング外部を排水溝により連通し、この排水溝の下端に貯水部を設けて、集水手段に集水した結露水を排水溝からケーシング外部に排水し、排水した結露水を貯水部に貯留して成長させ、結露水の成長によって吸着材への接触を円滑に促すものである。
【００１９】
また、貯水部と吸着材の間隔を２ｍｍ以下に設定して、貯水部からの結露水の滑落を抑制するものである。
【００２０】
また、貯水部の下方に平板状の弾性体を吸着材に向けて取り付けて、貯水部から滑落する結露水を弾性体で受け止めて吸着材に再接触させるものである。
【００２１】
また、弾性体と吸着材の間隔を貯水部と吸着材の間隔より狭めて、結露水の滑落を二段階で抑制し、更に寸法誤差や組付け誤差により弾性体が吸着材に接触しても、弾性体が吸収して吸着材の磨耗を防止するものである。
【００２２】
また、弾性体をフッ素ゴムで構成して、寸法誤差や組付け誤差による吸着材接触時の弾性体の磨耗を抑制するものである。
【００２３】
また、再生ファンを吸着材の吸湿部の通風方向における後段に配し、ケーシングの吸着材に対向する面を金属部材で形成して、室内空気の吸湿時に発生する吸着熱を金属部材を介してケーシング内の再生空気に伝達し、再生空気の温度を高めて相対湿度を低下させ結露を抑制するものである。
【００２４】
また、吸着材の回転方向において再生部の出口側に位置する吸着熱の発生量が多い吸湿部の通風方向後段に再生ファンを配して、吸着熱の再生空気への伝熱量を高めるものである。
【００２５】
また、金属部材にケーシングの内側に向けて複数の凸部を形成して、伝熱面積を増加させ伝熱量を高めるものである。
【００２６】
また、金属部材の逆面にケーシングの内側に向けて複数の突起部を形成して、再生空気の主流を温度の高い金属部材側に導くと共に撹拌して伝熱量を高めるものである。
【００２７】
また、金属部材に形成した複数の凸部と金属部材の逆面に形成した複数の突起部を相互に重ならないように配して、金属部材の凸部に伝熱面積の増加と撹拌の二重効果を持たせて伝熱量を高めるものである。
【００２８】
【実施例】
以下、本発明の実施例について図面を参照しながら説明する。なお、従来例と同じ構成要素については同じ符号を用い、詳細な説明を省略する。
【００２９】
図１は本発明の実施例における除湿装置の概略構成を示す簡易的な分解図である。図１に示すように、この除湿装置は本体１０１の外郭を形成するケース２０１に吸込口１０２と吹出口１０３を開口し、本体１０１内に吸込口１０２から室内の空気を吸込んで吹出口１０３より室内に吹出す処理ファン１０９を設けている。処理ファン１０９の前段には円筒状の吸着材１０７を回転軸２０２を中心に仕切板２０３に回転自在に取り付けて、吸着材１０７の外周に設けた駆動手段１０８の作動により回転移動を為すようにしている。また、吸着材１０７の一部を室内空気の通風方向後段側から扇型のボックス２０４によって覆蓋し、このボックス２０４に加熱手段１０６を内包して、吸着材１０７のボックス２０４覆蓋部分を再生部１０５、それ以外の部分を吸湿部１０４に区分している。吸湿部１０４には処理ファン１０９により室内空気を供給して吸着材１０７への吸湿を行い、再生部１０５にはボックス２０４に接続する再生ファン１１０により、加熱手段１０６を介して高温の再生空気を供給して吸着材１０７の脱湿再生を行う。再生ファン１１０はボックス２０４に近接して接続され、ボックス２０４同様に吸着材１０７の室内空気の通風方向後段側に配される。吸着材１０７の室内空気の通風方向前段には、入口管２０５と出口管２０６と水抜き穴１１３を有する中空状の凝縮器１１１を設け、再生部１０５に供給された再生空気を入口管２０５から凝縮器１１１内に導入し、出口管２０６から仕切板２０３に設けた接続管２０７を介して再生ファン１１０に戻すように連結して循環風路１１２を形成している。また、凝縮器１１１の外郭には通風可能な複数の通風孔２０８を開口し、この通風孔２０８に処理ファン１０９により送風される室内空気を通過させ、凝縮器１１１内を循環する再生空気をその露点温度以下に冷却して結露させる。凝縮器１１１内面に結露した再生空気中の水分は、その自重によって下方に滴下し水抜き穴１１３からタンク２０９に集水される。このタンク２０９を本体１０１から取り外して排水することにより結露水の処理が為されることになる。上記構成において、再生空気は循環風路１１２内を高露点状態で循環しており、凝縮器１１１の出口管からボックス２０４に至る経路では飽和蒸気となるため、その経路中に介在する再生ファン１１０において外部の雰囲気により冷やされて結露を生じることになる。
【００３０】
図２（ａ）（ｂ）（ｃ）は再生ファン１１０の詳細構成を示す斜視図及び分解図である。図２（ａ）（ｂ）に示すように再生ファン１１０は、モータ２１０の軸に締着した羽根２１１を吸引口２１２と吐出口２１３を開口したケーシング２１４に内包し、モータ２１０の駆動によって羽根２１１を回転させることにより、吸引口２１２から空気を吸い込んで吐出口２１３より吹き出す送風動作を為し得るものである。そして、前述したように本体１０１の組付け状態においては、吸引口２１２は仕切板２０３に設けた接続管２０７を介して凝縮器１１１の出口管２０６に接続され、吐出口２１３はボックス２０４に接続されることになる。また、ケーシング２１４は図２（ｃ）に示すように、モータ２１０を固定する樹脂部材２１５と吸引口２１２が開口した板状の金属部材２１６とから構成させており、金属部材２１６は本体１０１の組付け状態においては吸着材１０７に対向するように配される。
【００３１】
図３は樹脂部材２１５の詳細構成を示す斜視図である。図３に示すように樹脂部材２１５には結露した結露水を集水する集水手段２１７として、樹脂部材２１５の内面下方に設けた水受け部２１８に最下点２１９に向けて下り勾配を形成しており、樹脂部材２１５の内面に結露した水滴を自重により水受け部２１８に導き、下り勾配を利用して最下点２１９に集水するものである。また、集水した結露水を吸着材１０７に接触させる接触手段２２０として、水受け部２１８の最下点２１９から金属部材２１６との接触面２２１を貫通してケーシング２１４の外部に連通する排水溝２２２を形成し、この排水溝２２２の下端に結露水を貯留する貯水部２２３を設けている。そして、最下点２１９に集水した結露水を排水溝２２２を通じてケーシング２１４外部に排水し、排水された水滴を貯水部２２３で受け止めて表面張力を利用して成長させ、この水滴の成長によって吸着材１０７に円滑に接触させるものである。また、樹脂部材２１５の内面には再生空気を撹拌し且つ主流を金属部材２１６側に導くための複数の突起部２２４を形成している。
【００３２】
図４（ａ）（ｂ）はケーシング２１４内の再生空気の流れを流線にて示した説明図であり、図４（ａ）に示すように樹脂部材２１５に形成した突起部２２４により再生空気の主流が伝熱面である金属部材２１６に寄っている状態が確認でき、更に図４（ｂ）に示すように伝熱面である金属部材２１６に流れを拡散する効果を有していることが分かる。
【００３３】
図５は樹脂部材２１５に弾性体２２５を取り付けた構成を示す斜視図であり、図５に示すように、樹脂部材２１５の外面下端に弾性体２２５を接続するための連結部材２２６を螺子止めにより固定し、この連結部材２２６にフッ素ゴムを加工した平板状の弾性体２１５を吸着材１０７方向に向けて取り付けている。
【００３４】
図６（ａ）（ｂ）（ｃ）は樹脂部材２１５と弾性体２２５の本体１０１組付け時の吸着材１０７との位置関係を示した簡易的な縦断面図であり、図６（ａ）に示すように、ケーシング２１４は樹脂部材２１５に形成した接触手段２２０の貯水部２２３において吸着材１０７との間隔（図中矢符Ａ）が最短となるように配しており、更に弾性体２２５と吸着材１０７の間隔（図中矢符Ｂ）を貯水部２２３と吸着材１０７の間隔よりも短くなるように設けている。ここで矢符Ａの距離を２ｍｍ以下とすれば、除湿装置の本体１０１を傾けても貯水部２２３から結露水滴が滑落することは無く、吸着材１０７に確実に接触させて浸潤させることができる。また、その時の矢符Ｂの距離は限りなく０ｍｍに近くなり、図６（ｂ）に示すように組付けが悪く矢符Ａの距離が２ｍｍ以上となって貯水部２２３から結露水滴が滑落しても弾性体２２５で受け止めて吸着材１０７に再接触させることが可能である。また、図６（ｃ）に示すように組付け具合によって矢符Ａの距離が２ｍｍ未満となった場合は、弾性体２２５と吸着材１０７が接触することになるが、接触した余剰分は弾性体２２５の変形により吸収されるので、吸着材１０７にストレスが加わらず破損を防止できる。更に弾性体２２５はフッ素ゴムで形成されているので弾性体２２５の磨耗も抑制できる。
【００３５】
図７（ａ）（ｂ）（ｃ）は本実施例の除湿装置に用いる金属部材２１６の形状パターンを示す斜視図である。図７（ａ）に示した金属部材２１６は平板状のものであり、図７（ｂ）及び図７（ｃ）に示した金属部材２１６は絞り加工により凸部２２７を形成している。何れの金属部材２１６も本体１０１の組付け時には、吸着材１０７の吸湿部１０４に対向して配され、室内空気の吸湿時に発生する吸着熱を金属部材２１６自身を介してケーシング２１４内の再生空気に伝達する作用を持つ。従って金属部材２１６の材質は熱伝導率が高く、更に高湿の再生空気による錆の発生を抑制するため防錆加工を施したものが好ましく、例えば、ステンレス板、或いは防錆処理した鉄板及びアルミ板を用いることができる。そして図７（ｂ）のように長円状に凸部２２７を形成したり、図７（ｃ）のように凸部２２７を半球状に突出すれば、伝熱面積が増加して吸着熱の伝達量を高めることができるのである。更に樹脂部材２１５との組付けにおいては、突起部２２４と凸部２２７を互い違いに重ならないように配すれば、再生空気の拡散を促して金属部材２１６の伝熱面をより有効に活用することができる。
【００３６】
図８は吸着材１０７、再生ファン１１０及びボックス２０４の仕切板２０３への組付け状態を処理ファン１０９側から示した縦断面図であり、図８に示すように吸着材１０７の上方左側を加熱手段１０６を内包したボックス２０４で覆該して再生部１０５を形成し、ボックス２０４の右側面に吐出側が吸湿部１０４に重なるように再生ファン１１０を接続している。吸着材１０７は駆動手段１０８により矢符Ａに示す方向に回転するので、再生ファン１１０は吸着材１０７の回転方向において再生部１０５の出口側に位置する吸湿部１０４の通風方向後段側に配されることになる。羽根２１１の回転により吐出口２１３に向かう再生空気は、その主流を矢符Ｂに示す方向に向けて拡散しながらケーシング２１４内を流れ、吸着材１０７の回転方向に対しては略対向した流れとなる。室内空気からの吸湿により発生する吸着熱は再生部１０５から吸湿部１０４に移動した直後が最も多く、回転が進むにつれ除々に減少するので、矢符Ｂに示す再生空気は金属部材２１６を介して授受する熱量においても対向流となり効率良く昇温されて結露を抑制することになる。また、ケーシング２１４内に発生した結露水を貯留する貯水部２２３は図中点Ｃに位置し、貯水部２２３で成長した結露水滴は点Ｃと通風方向で同軸となる吸着材１０７の回転軸２０２近傍の吸湿部１０４に接触する。接触した結露水滴は吸着材１０７の回転に伴い矢符Ｄに示すように吸湿部１０４を移動し、その間に吸着材１０７に十分浸潤して拡散し再生部１０５に入る。再生部１０５では吸着材１０７の結露水接触面が加熱手段１０６に対向して近接し、加熱手段１０６の熱を直接的に利用して吸着材１０７に浸潤した結露水滴を十分に脱湿乾燥し、再び浸潤可能な状態に再生して吸湿部１０４に戻す。脱湿した結露水は凝縮器１１１に導入されて再結露しタンク２０９に滴下して処理される。また、点Ｃに示す吸着材１０７の結露水接触部は回転軸２０２近傍の吸着材１０７内周寄りに位置するので室内空気の吸湿量には影響を及ぼさず、更に再生部１０５においては回転軸２０２近傍が比較的低温で加熱されるので連続的な加水加熱による吸着材１０７の劣化も生じない。
【００３７】
上記した構成により、本実施例の除湿装置は、再生ファン１１０内に生じる結露水の発生量を毎時２ｃｃ以内に抑制でき、更に発生した結露水を再生ファン１１０に滞留させずに、その全量を吸着材１０７に浸潤させて処理し、再生ファン１１０の所定風量を維持して安定した除湿量を確保することができるものである。
【００３８】
なお、本実施例に用いる吸着材１０７としては、吸着材１０７が比較的湿分を多く含むときに相対的に湿度の低い空気、例えば加熱された再生空気が通過すると通過空気中に水分を放湿し、吸着材１０７が比較的乾燥しているときに相対的に湿度の高い空気、例えば室内空気が通過すると通過空気中の水分を吸湿する性質を有するものであれば良く、例えば、セラミック繊維、ガラス繊維等の無機繊維、もしくはそれら無機繊維とパルプとを混合して抄造した平面紙とコルゲート加工を施した波型紙とを積層して巻き上げて円盤状に形成し、ゼオライト、シリカゲル、活性炭などの吸着材料を１種類以上担持したものを用いることが可能である。
【００３９】
また、吸着材１０７を回転移動させる駆動手段１０８としては、ＡＣインダクタモータを使用すれば良く、モータの軸にギアを締着して吸着材１０７の外周に設けたギアに噛み合わせれば容易に回転駆動が可能である。そして、吸着材１０７の回転速度を毎時２０回転から４０回転に調整すれば吸着と脱着をバランス良く実行することができる。
【００４０】
また、再生部を加熱する加熱手段１０６としては、例えば、ニクロムヒーター、セラミックヒーター、シーズヒーター、輻射ヒーター等の電気式ヒーターを用いれば良く、更にはヒーターに限らず再生空気を昇温可能なものであれば良いのであって、内部に高温の流体が流れる熱交換器を使用することも可能である。その熱交換器の内部を流す高温の流体としては、温水ボイラ、ＣＯ_２ヒートポンプ給湯機、コージェネ排熱等を熱源とする温水、或いは直膨式ヒートポンプを熱源とするＲ４１０Ａ、ＣＯ２等の冷媒を用いれば良い。

The operation of the dehumidifier configured as described above will be described. Indoor air is sucked from the suction port 102 by the processing fan 109 and supplied to the condenser 111 to cool the high-humidity regenerated air and supply it to the moisture absorbing section 104. Is done. In the moisture absorbing section 104, the indoor air is absorbed by the adsorbent 107 to become dry air, and is blown out from the outlet 103 into the room. On the other hand, the regeneration air created by the regeneration fan 110 is heated by the heating means 106 to a high temperature and supplied to the regeneration unit 105. After the moisture is dehumidified from the adsorbent 107 in the regenerating unit 105 and becomes high in humidity, the air is cooled to the dew point temperature or lower by the indoor air in the condenser 111 and is sucked into the regenerating fan 110 and circulated. Due to this circulation, the regeneration air maintains a dew point higher than the temperature of the room air to promote dew condensation in the condenser 111. The moisture in the regenerated air cooled to a dew point temperature or lower in the condenser 111 becomes condensed water and is discharged to the outside through the drain hole 113, and the amount of the condensed water discharged becomes the dehumidification amount of the dehumidifier. Since there is a limit to the amount of moisture absorbed by the adsorbent 107, the adsorbent 107 is rotationally moved by the driving unit 108, and the moisture absorption in the moisture absorption unit 104 and the dehumidification regeneration in the regeneration unit 105 are continuously switched and repeatedly executed. , Enables long-term continuous dehumidification.

[0029]
FIG. 1 is a simplified exploded view showing a schematic configuration of a dehumidifier according to an embodiment of the present invention.

Further, a part of the adsorbent 107 is covered by a fan-shaped box 204 from the rear side in the ventilation direction of the room air, and the box 204 is provided with the heating means 106. , And other portions are divided into moisture absorbing portions 104. Room air is supplied to the moisture absorbing section 104 by the processing fan 109 to absorb moisture into the adsorbent 107, and high temperature regenerated air is supplied to the regenerating section 105 via the heating means 106 by the regenerating fan 110 connected to the box 204. The adsorbent 107 is supplied to perform dehumidification regeneration. The regeneration fan 110 is connected close to the box 204 and, like the box 204, is disposed downstream of the adsorbent 107 in the ventilation direction of the room air. A hollow condenser 111 having an inlet pipe 205, an outlet pipe 206, and a drain hole 113 is provided at a stage upstream of the adsorbent 107 in the ventilation direction of the indoor air, and the regenerated air supplied to the regenerating unit 105 is supplied from the inlet pipe 205 through the inlet pipe 205. The air is introduced into the condenser 111, and is connected back to the regeneration fan 110 from the outlet pipe 206 via a connection pipe 207 provided on the partition plate 203 to form a circulation air passage 112. A plurality of ventilation holes 208 capable of ventilation are opened in the outer periphery of the condenser 111, and the room air blown by the processing fan 109 is passed through the ventilation holes 208, and the regenerated air circulating in the condenser 111 is supplied to the ventilation hole 208.

The moisture in the regenerated air that has condensed on the inner surface of the condenser 111 drips downward by its own weight and is collected in the tank 209 from the drain hole 113. By removing the tank 209 from the main body 101 and draining the water, the dew water is treated. In the above configuration, the regeneration air circulates in the circulation air passage 112 at a high dew point, and becomes saturated steam in the path from the outlet pipe of the condenser 111 to the box 204. Therefore, the regeneration fan 110 Is cooled by an external atmosphere to cause dew condensation.
[0030]
2A, 2B, and 2C are a perspective view and an exploded view showing a detailed configuration of the reproduction fan 110. FIG. As shown in FIGS. 2A and 2B, the regenerating fan 110 includes a blade 211 fastened to a shaft of a motor 210 in a casing 214 having a suction port 212 and a discharge port 213 opened. By rotating 211, air can be blown from suction port 212 and blown out from discharge port 213. As described above, in the assembled state of the main body 101, the suction port 212 is connected to the outlet pipe 206 of the condenser 111 via the connection pipe 207 provided on the partition plate 203, and the discharge port 213 is connected to the box 204.

In the assembled state, it is arranged to face the adsorbent 107.
[0031]
FIG. 3 is a perspective view illustrating a detailed configuration of the resin member 215. As shown in FIG. 3, the resin member 215 has a water collecting means 217 for collecting dew condensation water, and a water receiving part 218 provided below the inner surface of the resin member 215 has a downward gradient toward the lowest point 219. Water droplets condensed on the inner surface of the resin member 215 are guided to the water receiving portion 218 by its own weight, and collected at the lowest point 219 by using a downward gradient. Further, as a contact means 220 for bringing the collected dew water into contact with the adsorbent 107, a drain groove communicating from the lowest point 219 of the water receiving portion 218 to the outside of the casing 214 through the contact surface 221 with the metal member 216. A drain 222 is provided at the lower end of the drain groove 222 for storing dew water. Then, the condensed water collected at the lowest point 219 is drained to the outside of the casing 214 through the drain groove 222, and the drained water droplets are received by the water storage part 223 and grown by utilizing the surface tension. This is to make the contact with the material 107 smoothly. Further, a plurality of protrusions 224 are formed on the inner surface of the resin member 215 for stirring the regeneration air and guiding the main flow to the metal member 216 side.
[0032]
FIGS. 4A and 4B are explanatory diagrams showing the flow of the regeneration air in the casing 214 by streamlines. As shown in FIG. 4A, the projection air 224 formed on the resin member 215 causes the regeneration air to flow. Can be confirmed that the main flow is shifted to the metal member 216 as the heat transfer surface, and further has the effect of diffusing the flow to the metal member 216 as the heat transfer surface as shown in FIG. I understand.
[0033]
FIG. 5 is a perspective view showing a configuration in which the elastic member 225 is attached to the resin member 215. As shown in FIG. 5, a connecting member 226 for connecting the elastic member 225 to the lower end of the outer surface of the resin member 215 is screwed. The connecting member 226 is fixed, and a flat elastic body 215 formed by processing fluoro rubber is attached to the connecting member 226 toward the adsorbent 107.
[0034]
FIGS. 6A, 6B, and 6C are simplified vertical cross-sectional views showing the positional relationship between the resin member 215 and the adsorbent 107 when the elastic body 225 is attached to the main body 101, and FIG. As shown in the figure, the casing 214 is arranged so that the distance (arrow A in the figure) between the adsorbent 107 and the water storage part 223 of the contact means 220 formed on the resin member 215 is minimized. The interval between the adsorbents 107 (arrow B in the figure) is provided to be shorter than the interval between the water storage section 223 and the adsorbent 107. Here, if the distance of the arrow A is 2 mm or less, even if the main body 101 of the dehumidifier is tilted, the dew condensation water droplets do not slide down from the water storage part 223, and can be surely brought into contact with the adsorbent 107 and infiltrated. . In addition, the distance of the arrow B at that time is infinitely close to 0 mm, and as shown in FIG. 6B, the assembly is poor, and the distance of the arrow A is 2 mm or more, and the dew condensation water drops from the water storage part 223. Even if it is, it can be received by the elastic body 225 and brought into contact with the adsorbent 107 again. When the distance of the arrow A is less than 2 mm due to the mounting condition as shown in FIG. 6C, the elastic body 225 and the adsorbent 107 come into contact with each other. Since the adsorbent 107 is absorbed by the deformation of the body 225, no stress is applied to the adsorbent 107, so that damage can be prevented. Further, since the elastic body 225 is made of fluoro rubber, wear of the elastic body 225 can be suppressed.
[0035]
FIGS. 7A, 7B, and 7C are perspective views showing a shape pattern of the metal member 216 used in the dehumidifier of the present embodiment. The metal member 216 shown in FIG. 7A has a flat plate shape, and the metal member 216 shown in FIGS. 7B and 7C has a projection 227 formed by drawing. When the main body 101 is assembled, any of the metal members 216 is disposed so as to face the moisture absorbing portion 104 of the adsorbent 107, and the heat of adsorption generated at the time of absorbing the indoor air is absorbed by the regenerated air in the casing 214 via the metal member 216 itself. Has the effect of transmitting to. Therefore, the material of the metal member 216 is preferably a material having a high thermal conductivity, and further subjected to a rust-preventing process in order to suppress the generation of rust due to the high-humidity regenerated air. A plate can be used. If the convex portion 227 is formed in an elliptical shape as shown in FIG. 7B or the convex portion 227 is projected in a hemispherical shape as shown in FIG. The amount of transmission can be increased. Further, in assembling with the resin member 215, if the protrusions 224 and the protrusions 227 are arranged so as not to alternately overlap, the diffusion of the regeneration air is promoted, and the heat transfer surface of the metal member 216 is more effectively utilized. Can be.
[0036]
FIG. 8 is a vertical cross-sectional view showing the assembled state of the adsorbent 107, the regenerating fan 110, and the box 204 to the partition plate 203 from the processing fan 109 side. As shown in FIG. The regenerating unit 105 is formed by covering the box with the means 106 therein, and a regenerating fan 110 is connected to the right side of the box 204 so that the discharge side overlaps the moisture absorbing unit 104. Since the adsorbent 107 is rotated in the direction indicated by the arrow A by the driving means 108, the reproducing fan 110 is disposed on the downstream side in the ventilation direction of the moisture absorbing part 104 located at the outlet side of the reproducing part 105 in the rotational direction of the adsorbent 107. Will be. The regenerated air flowing toward the discharge port 213 due to the rotation of the blade 211 flows through the casing 214 while diffusing the main flow in the direction indicated by the arrow B, and flows substantially opposite to the rotation direction of the adsorbent 107. Become. The heat of adsorption generated by the absorption of moisture from the indoor air is the largest immediately after moving from the regeneration unit 105 to the moisture absorption unit 104, and gradually decreases as the rotation proceeds, so that the regeneration air indicated by the arrow B passes through the metal member 216. Even in the amount of heat to be transferred, the flow becomes a counter flow and the temperature is efficiently raised to suppress dew condensation. Further, a water storage portion 223 for storing the dew condensation water generated in the casing 214 is located at a point C in the figure, and the dew condensation water droplets grown in the water storage portion 223 are coaxial with the point C in the ventilation direction. It comes into contact with the nearby moisture absorbing portion 104. The condensed water droplets move in the moisture absorbing section 104 as shown by the arrow D with the rotation of the adsorbent 107, and during this time, sufficiently penetrate and diffuse into the adsorbent 107 and enter the regenerating section 105. In the regenerating section 105, the dew-water contact surface of the adsorbent 107 is opposed to and close to the heating means 106, and the heat of the heating means 106 is directly used to sufficiently dehumidify and dry the dew-water droplets infiltrating the adsorbent 107. Then, it is regenerated to a state capable of infiltration and returned to the moisture absorbing section 104. The dehumidified condensed water is introduced into the condenser 111, dew-condensed again, and dropped into the tank 209 for processing. Further, since the dewed water contact portion of the adsorbent 107 shown at the point C is located near the inner periphery of the adsorbent 107 near the rotating shaft 202, it does not affect the moisture absorption of the indoor air. Since the vicinity of 202 is heated at a relatively low temperature, the adsorbent 107 does not deteriorate due to continuous water heating.
[0037]
With the above-described configuration, the dehumidifier of the present embodiment can suppress the amount of dew water generated in the regeneration fan 110 to within 2 cc per hour, and further reduce the entire amount of generated dew water without remaining in the regeneration fan 110. The treatment is performed by infiltrating the adsorbent 107, and a predetermined air volume of the regenerating fan 110 can be maintained to secure a stable dehumidification amount.
[0038]
As the adsorbent 107 used in this embodiment, when the adsorbent 107 contains a relatively large amount of moisture, air having a relatively low humidity, for example, when heated regeneration air passes, moisture is released into the passing air. When the adsorbent 107 is relatively dry, the air having relatively high humidity, for example, indoor air, may have a property of absorbing moisture in the passing air. Inorganic fibers such as glass fibers, or a mixture of these inorganic fibers and pulp, and a flat paper made from paper and a corrugated corrugated paper are laminated and rolled up to form a disk, and zeolite, silica gel, activated carbon, etc. It is possible to use one carrying at least one kind of adsorbing material.
