The heat quantity discharged out of the dehumidifier is reduced, and the power consumption is reduced. Moisture absorption efficiency of the moisture absorber 2 is improved by taking the air 7d for regeneration into a moisture absorption passage A, condensation efficiency of a condenser 3 is improved by constituting the condenser 3 so that condensed water 19 is not reserved in the bottom of the condenser 3, and hence the dehumidifier 1 is miniaturized. <P>COPYRIGHT: (C)2004,JPO

Description

【０００１】
【発明の属する技術分野】
本発明は、除湿機に関し、特に吸湿剤を用いて除湿を行う、乾式除湿機に関するものである。
【０００２】
【従来の技術】
従来の除湿機は、図１に示すように、除湿機１外部から送風機４によって取り入れられた吸湿用空気１４ａが、２経路を持った凝縮器３の一方の通路（以下、低温通路３ａと呼ぶ）を通った後、内部にシリカゲルなどの吸湿剤２６が充填され、風路を２分割された回転式の吸湿器２の一方の風路（以下、吸湿部２ａと呼ぶ）を通って吸湿され、除湿機１の外部へ乾燥空気１４ｂが放出される吸湿経路Ａが構成されている。
【０００３】
また、吸湿用空気１４ａに含まれる水分を吸収した吸湿剤２６を再生するために、除湿機１外部から送風機６によって取り入れられた再生用空気７ａは、再生用ヒータ５によって昇温され（７ｂ）、吸湿器２内の吸湿剤２６を乾燥させる。水分を含んだ高温の再生用空気７ｃは、前記凝縮器３の他方の通路（以下、高温通路３ｂと呼ぶ）を通ることで、低温通路３ａ内を通る吸湿用空気１４ａと熱交換されて冷却及び凝縮され、除湿機１の外部へ放出される再生経路Ｂが構成されている。
【０００４】
凝縮器３に流入する再生用空気７ｃは、冷却されるため、水分が凝縮され、凝縮水１９となって落下する。この時に飽和水蒸気量が少ないほうが、多くの水分を凝縮できるので、できるだけ低温に冷却した方が望ましい。また、再生経路Ｂ内に凝縮水１９が溜まらないように、凝縮水１９を受ける貯水部１０と、貯水部１０にあけられた孔１０ａから落下する凝縮水２０を受ける貯水槽２７が配されている。
【０００５】
また、図２は、他の従来例を示し、再生経路Ｂが、循環した閉回路を構成した再生用空気循環式除湿機である。凝縮器３を通過後の再生用空気７ｄは、再生用ヒータ５で、昇温され、吸湿器２の再生部２ｂを通って吸湿剤２６を再生し、凝縮器３で凝縮される。この構成によると、凝縮後の高湿度の再生用空気７ｄが除湿機１外へ放出されないため、前述の例と比較して除湿効果が高くなる。
【０００６】
また、図３に凝縮器３の詳細を示す。凝縮器３は、図３における（ａ）に示すように、吸湿経路Ａの低温通路３ａと再生経路Ｂの高温通路３ｂとは直交しており、図３における（ｂ）に示すような、内部が多数の通路に分割されたシート２２，２３が互いに直交して複数段交互に積層固着されて構成されている。シート２２，２３の固着面２２ａ，２３ａは、極力薄く、また接触面積が大きく形成され、低温通路３ａを通る吸湿用空気１４ａと、高温通路３ｂを通る再生用空気７ｃとの間の熱交換の効率を向上させている。
【０００７】
熱交換によって冷却された再生用空気７ｃは、図３における（ｃ）に示す高温通路３ｂの断面図のように、水分が凝縮されて、凝縮水１９となり、凝縮水１９は自重により高温通路３ｂ内を落下して排出される。
【０００８】
【発明が解決しようとする課題】
このような構成の除湿機において、吸湿器２が吸湿用空気１４ａから水分を吸収する際には吸着熱が発生し、凝縮器３が、再生用空気７ｃを凝縮する際には凝縮熱が発生する。また、吸湿剤２６を再生するためには、再生用空気７ｂは、約１４０℃以上に加熱される必要があるため、再生用ヒータ５には、送風機６により決定される風量の再生用空気７ｂを昇温させる電力が必要である。
【０００９】
再生用空気７ｂの昇温時に再生用ヒータ５によって発生する余熱は、前記の吸着熱と凝縮熱とともに、除湿機１から放出されて、使用される部屋の室温を上昇させ、ユーザに不快感を与える要因となる。また、余熱分のエネルギーが再生用ヒータ５によって余分に消費されるので、除湿機１の消費電力を大きくしていた。
【００１０】
また、乾式の除湿機は、コンプレッサ式除湿機などと比較し、静音であるが形状が大きくなるという欠点があった。
【００１１】
また、図３における（ｃ）に示すように、高温通路３ｂ内を壁面に伝って成長しながら落下してきた凝縮水１９は、凝縮器３の下端面３０で表面張力によってある程度の重量になるまでは落下せずに留まり、大きな水滴１９ａとなって高温通路３ｂを塞でいた。
【００１２】
この水滴１９ａによって、高温通路３ｂが部分的に塞がれることにより、再生用空気７ｃの通過面積が減少して熱交換を行う面積が少なくなり、さらに、通過面積が減少し、送風機６による風量が一定であるために再生用空気７ｃが凝縮器３を通過する速度が速くなることで、凝縮効率を悪化させる要因となっていた。
【００１３】
また、再生用空気循環式除湿機においては、凝縮器３の貯水部１０に開けられた孔１０ａは、再生用空気７ｄが閉じた再生経路Ｂからできる限り漏れないように、最小限の大きさに開けられている。しかし、再生経路Ｂにおいて、凝縮器３の高温通路３ｂが細管状となっているため最も通気抵抗が大きく、凝縮器３を通過後の再生用空気７ｄの気圧が大気圧よりも低くなり、孔１０ａから凝縮水１９が排出されにくくなることによって再生経路Ｂに凝縮水１９が溜まる要因となっていた。
【００１４】
また、除湿機１を運転する際に、湿度は、温度に比較して体感しにくいため、ユーザが除湿効果を確認しにくかった。
【００１５】
また、再生経路Ｂは、高湿度状態であり、除湿機１を運転停止後に、再生経路Ｂが室温まで低下した際には、再生経路Ｂのほぼ全体が露点温度に達している。再生経路Ｂは、高湿度の再生用空気７ｄの排出を少なくするために、細い経路で構成されているので（例えば吸湿経路Ａの１／１０）、除湿機１の運転停止後長時間放置しても乾燥しにくく、かびの発生、雑菌の繁殖、金属部の腐食などの問題があった。
【００１６】
本発明は、外部へ放出される熱を低減し、消費電力の少ない除湿機を提供することを目的とする。
【００１７】
また、本発明は、小型でコストパフォーマンスに優れた除湿機を提供することを目的とする。
【００１８】
また、本発明は、安定した凝縮効率を得ることのできる除湿機を提供することを目的とする。
【００１９】
また、本発明は、凝縮水の排出をスムーズに行うことが可能な除湿機を提供することを目的とする。
【００２０】
また、本発明は、運転効果を容易に確認可能な除湿機を提供することを目的とする。
【００２１】
また、本発明は、かびや雑菌の発生及び金属の腐食を防止した除湿機を提供することを目的とする。
【００２２】

【００２５】
この構成によると、再生用ヒータで昇温された再生用空気は、吸湿器の再生部における吸湿器回転方向前方を通り、吸湿剤を再生した後、熱交換器を通り熱交換器に余熱を与える。また、吸湿用空気の一部は、再生用空気が通った熱交換器の区域と隣接した区域を通って熱交換器の伝導熱を受け取り、吸湿器の再生部における吸湿器回転方向後方を通り、吸湿剤に予熱を与える熱回収回路を構成する。
【００２６】
また、本発明は、回転式の吸湿器と、前記吸湿器内部に充填され、水分を吸収する吸湿剤と、前記吸湿器内の風路を分割された吸湿部を通り、吸湿用空気から水分を吸収する吸湿経路と、前記吸湿器内の風路を分割された再生部を通り、前記吸湿剤を再生する再生経路と、前記再生経路内を通り再生用空気を昇温する再生用ヒータと、前記再生用空気内の水分を凝縮させて除去する凝縮器とを備えた除湿機において、低温流体と高温流体との間で熱交換を行う回転式の熱交換器を有し、前記熱交換器は、前記熱交換器の回転方向前方より順に、第１熱交換区域と第２熱交換区域に風路を分割され、前記吸湿器の前記再生部は、前記吸湿器の回転方向前方より順に、第１再生区域と第２再生区域に風路を分割されており、前記再生用空気は、前記再生用ヒータ、前記第１再生区域、前記第２熱交換区域の順に通過し、前記吸湿用空気の一部は、前記第１熱交換区域、前記第２再生区域の順に通過し、前記吸湿器から熱回収する。
【００２７】
この構成によると、再生用ヒータで昇温された再生用空気は、吸湿器の再生部における吸湿器回転方向前方を通り、吸湿剤を再生した後、回転式の熱交換器を通り余熱を与える。また、吸湿用空気の一部は、熱交換器内の再生経路と隣接した該熱交換器の回転方向後方を通って熱を受け取り、吸湿器の再生部における吸湿器回転方向後方を通り、吸湿剤に予熱を与える熱回収回路を構成する。

【００２９】
この構成によると、凝縮器を通った相対湿度１００％の再生用空気は、吸湿器の吸湿部を通って吸湿された後除湿機外に放出され、吸湿剤に吸収された水分は、再生経路を通って凝縮される。
【００３０】
また、本発明は、回転式の吸湿器と、前記吸湿器内部に充填され、水分を吸収する吸湿剤と、前記吸湿器内の風路を分割された吸湿部を通り、吸湿用空気から水分を吸収する吸湿経路と、前記吸湿器内の風路を分割された再生部を通り、前記吸湿剤を再生する再生経路と、前記再生経路内を通り再生用空気を昇温する再生用ヒータと、前記再生用空気内の水分を凝縮させて除去する凝縮器とを備えた除湿機において、前記再生経路における前記凝縮器の出口側形状を、長溝状としている。

【００３３】
この構成によると、循環した再生経路において、凝縮器を通過した再生用空気は、通気抵抗を受け、凝縮器の出口付近の気圧が高くなる。
【００３４】
また、本発明は、回転式の吸湿器と、前記吸湿器内部に充填され、水分を吸収する吸湿剤と、前記吸湿器内の風路を分割された吸湿部を通り、吸湿用空気から水分を吸収する吸湿経路と、前記吸湿器内の風路を分割された再生部を通り、前記吸湿剤を再生する再生経路と、前記再生経路内を通り再生用空気を昇温する再生用ヒータと、前記再生用空気内の水分を凝縮させて除去する凝縮器とを備えた除湿機において、前記凝縮器を通過後の前記再生経路を構成する部材が、前記再生経路内部の少なくとも一部を可視できる材料で構成されている。
【００３５】
この構成によると、凝縮器を通った後の再生経路の一部は、除湿機外より視認できる状態で、除湿が行われる。
【００３６】
また、本発明は、回転式の吸湿器と、前記吸湿器内部に充填され、水分を吸収する吸湿剤と、前記吸湿器内の風路を分割された吸湿部を通り、吸湿用空気から水分を吸収する吸湿経路と、前記吸湿器内の風路を分割された再生部を通り、前記吸湿剤を再生する再生経路と、前記再生経路内を通り再生用空気を昇温する再生用ヒータと、前記再生用空気内の水分を凝縮させて除去する凝縮器とを備えた除湿機において、前記吸湿経路の送風機を停止時に、前記再生経路の送風機と前記再生用ヒータとを運転可能としている。
【００３７】
この構成によると、除湿機の運転停止後に、再生経路の送風機を運転した際に、吸湿用空気は流れずに、高温の乾燥した再生用空気が再生経路に流れる。
【００３８】
【発明の実施の形態】
本発明における第１の実施形態を図４及び図５を参照して説明する。図４は、第１実施形態の構成図であり、図５は吸湿器２の部分を説明する概略図である。なお、従来例と同一の構成部材においては、同一の番号を付している。
【００３９】
図において、吸湿器２は、吸湿器２の回転方向（矢印２４）の前方より順に放熱区域２ｂａ、再生区域２ｂｂ、受熱区域２ｂｃに、風路を分割されている。再生用ヒータ５によって昇温された再生用空気７ｂは、吸湿器２の再生部２ａの再生区域２ｂｂを通り、吸湿剤２６の再生を行う。再生区域２ｂｂを通過した再生用空気７ｂ２は、再生用空気７ｂよりも温度が下がっているが、まだ高温状態であるので、再度、吸湿器２の再生部２ｂにおける、受熱区域２ｂｃを通って吸湿剤２６に余熱を与える。予熱された受熱区域２ｂｃの吸湿剤２６は、吸湿器２の矢印２４方向の回転に伴い前記の再生区域２ｂｂへ移動する
【００４０】
受熱区域２ｂｃを通った再生用空気７ｃは、凝縮器３を通って冷却及び凝縮され、冷却された再生用空気７ｄは、吸湿器２の放熱区域２ｂａを通る。再生区域２ｂｂで加熱された吸湿剤２６は、吸湿器２の回転に伴い放熱区域２ｂａへ移動しているので、再生用空気７ｄは、吸湿剤２６から予熱され、再生用空気７ｄ２となって再生用ヒータ５によって昇温される。
【００４１】
この構成によると、図５に示すように、再生用空気７ｄ２が、放熱区域２ｂａと再生区域２ｂｂを介して吸湿剤２６の熱を回収する第１の熱回収回路Ｄが形成されることにより、再生用空気７ｄ２は、再生用ヒータ５で加熱される前に予め昇温されるので、再生用ヒータ５の、加熱エネルギーを低減可能となる。
【００４２】
また、受熱区域２ｂｃの吸湿剤２６が、再生用空気７ｂ２の予熱を回収して再生区域２ｂｂに引き渡す第２の熱回収回路Ｅが形成されることにより、吸湿剤２６が再生区域に位置する前に予め昇温されるので、吸湿剤２６の再生に必要な温度まで再生空気７ｂを昇温させる、再生用ヒータ５の加熱エネルギーを低減可能である。
【００４３】
なお、図４において、再生経路Ｂを循環した閉回路としているが、放熱区域２ｂａに入る再生用空気７ｄを除湿機１の外部から取り入れ、凝縮器３を通過した再生用空気７ｄを除湿機１の外部へ放出する開回路でも同様の効果を得ることができる。
【００４４】
次に、第２実施形態を図６及び図７を参照して説明する。図６は、第２実施形態の構成図であり、図７は吸湿器２及び熱交換器８の部分を説明する概略図である。なお、従来例と同一の構成部材においては、同一の番号を付している。
【００４５】
同図において、吸湿器２に隣接して、吸湿器２の再生部２ｂから吸湿部２ａの一部にかけて形成される熱交換器８が配置され、再生用ヒータ５によって昇温された再生用空気７ｂは、吸湿器２の再生部２ｂを通って吸湿剤２６を再生した後、熱交換器８内の再生経路Ｂ１を通って凝縮器３へ送られる。熱交換器８は、伝熱性の高い材料で形成され、吸湿器２を通ったまだ高温状態の再生用空気７ｂは、熱交換器８に余熱を与える。
【００４６】
吸湿経路Ａから分岐した吸湿経路Ａ２を通る吸湿用空気１４ｃは、熱交換器８内の再生経路Ｂ１と隣接した吸湿経路Ａ１を通って、再生経路Ｂ１からの伝導熱を与えられ、吸湿器２の再生部２ｂと隣接して回転方向（矢印２４）の後方側に位置する受熱部２ｃを通り吸湿剤２６に予熱を与え、受熱部２ｃ内の吸湿剤２６は回転によって再生部２ｂへ移動する。吸湿器２を通った吸湿用空気１４ｄは、吸湿剤２６により水分を除去されているので吸湿経路Ａに戻り、除湿機１外へ放出される。
【００４７】
この構成によると、昇温された再生用空気７ｂの余熱を熱交換器８と吸湿用空気７ｂを介して吸湿剤２６が回収する回収回路Ｆが形成されることにより、吸湿剤２６が再生区域に位置する前に予め昇温されるので、吸湿剤２６の再生に必要な温度まで再生空気７ｂを昇温させる、再生用ヒータ５の加熱エネルギーを低減可能である。
【００４８】
なお、図６において、吸湿経路Ａ２が、吸湿経路Ａから分岐した構成を示しているが、吸湿経路Ａの一部が熱交換器８内の吸湿経路Ａ１にかかるように構成すれば、吸湿経路Ａ２を分岐させなくても同様の効果を期待することができる。
【００４９】
次に、第３実施形態を図８及び図９を参照して説明する。図８は、第３実施形態の構成図であり、図９は吸湿器２及び回転式の熱交換器９の部分を説明する概略示図である。なお、従来例と同一の構成部材においては、同一の番号を付している。

同図において、吸湿器２に隣接した位置に回転式の熱交換器９が配置され、再生用ヒータ５によって昇温された再生用空気７ｂは、吸湿器２の再生部２ｂを通って吸湿剤２６を再生した後、熱交換器９内の受熱部９ａを通って凝縮器３へ送られる。吸湿器２を通ったまだ高温状態の再生用空気７ｂは、熱交換器９に余熱を与える。
【００５１】
吸湿経路Ａから分岐した吸湿経路Ａ２を通る吸湿用空気１４ｃは、熱交換器９内の受熱部９ａと隣接した放熱部９ｂを通る。熱交換器９の受熱部９ａの吸湿剤２６は、熱交換器９の矢印２５方向の回転によって放熱部９ｂに移動しているため、吸湿用空気１４ｃは熱交換器９の放熱部９ｂから熱を与えられ、吸湿器２の再生部２ａと隣接して回転方向（矢印２４）の後方側に位置する吸湿器２の受熱部２ｃを通り吸湿剤２６に予熱を与え、吸湿器２の受熱部２ｃ内の吸湿剤２６は矢印２４方向の回転によって再生部２ｂへ移動する。吸湿器２を通った吸湿用空気１４ｄは、吸湿剤２６により水分を除去されているので吸湿経路Ａに戻り、除湿機１外へ放出される。
【００５２】
この構成によると、昇温された再生用空気７ｂの余熱を熱交換器９と吸湿用空気７ｂを介して吸湿剤２６が回収する熱回収回路Ｇが形成されることにより、吸湿剤２６が再生区域に位置する前に予め昇温されるので、吸湿剤２６の再生に必要な温度まで再生空気７ｂを昇温させる、再生用ヒータ５の加熱エネルギーを低減可能である。
【００５３】
なお、図８において、吸湿経路Ａ２が、吸湿経路Ａから分岐した構成を示しているが、吸湿経路Ａの一部が熱交換器９内の放熱部９ａにかかるように構成すれば、吸湿経路Ａ２を分岐させなくても同様の効果を期待することができる。
【００５４】
以上の第１、第２及び第３の実施形態によると、再生用ヒータ５によって加熱された再生用空気７ｂ及び吸湿剤２６の余熱を回収することから、除湿機１外に放出される熱量が低減されるとともに、再生用ヒータ５が加熱を行うために必要な加熱エネルギーが低減され、再生用ヒータ５の消費電力を低減することができる。
【００５５】
なお、第２及び第３実施形態において、熱交換器８及び熱交換器９は、必ずしも吸湿器２に隣接する必要はなく離れた位置に構成しても同様の効果を得ることが可能であるが、できるだけ近い位置に配置した方が、熱交換器８，９と吸湿器２との間の、再生経路Ｂ及び吸湿経路Ａ２を短くでき、再生経路Ｂ及び吸湿経路Ａ２からの放熱量を少なくできるので望ましい。
【００５６】
また、第２及び第３実施形態において、再生経路Ｂ及び吸湿経路Ａ２は、対向流としているが、必ずしも対向流とする必要はなく図１４に示すように、平行流でも構成可能で、同様の効果を得ることが可能であるが、対向流とした方が、熱交換器８，９と吸湿器２との間の、再生経路Ｂ及び吸湿経路Ａ２を短くでき、再生経路Ｂ及び吸湿経路Ａ２からの放熱量を少なくできるので望ましい。
【００５７】
また、第３実施形態において、熱交換器９と吸湿器２の回転方向を逆方向としているが、必ずしも逆方向とする必要はなく図１５に示すように、同一方向でも構成可能で、同様の効果を得ることが可能であるが、逆方向とした方が、熱交換器９と吸湿器２との間の、再生経路Ｂ及び吸湿経路Ａ２を短くでき、再生経路Ｂ及び吸湿経路Ａ２からの放熱量を少なくできるので望ましい。
【００５８】
次に、第４実施形態を図１０を参照して説明する。なお、従来例と同一の構成部材においては、同一の番号を付している。図１０において凝縮器３を通過した再生用空気７ｄは、吸湿経路Ａにおける吸湿器２の上流側に合流し、吸湿器２の吸湿部２ａで、吸湿用空気１４ａとともに水分を吸収され除湿機１外へ放出される。
【００５９】
この構成によると、凝縮後、相対湿度がほぼ１００％の再生用空気７ｄを吸湿経路Ａに合流させることで、吸湿用空気１４ａの水分濃度を上げ、再生用空気７ｄに含まれた水分も吸湿器２によって吸湿することになるので、除湿効果を向上させることができるため、吸湿器２を小型化することが可能である。
【００６０】
次に、第５実施形態を図１１を参照して説明する。先に説明した図３と同一の構成部材においては、同一の番号を付している。図１１において、（ａ）は、第５実施形態における凝縮器３の斜視図を示し、（ｂ）は、高温通路３ｂの縦断面図を示している。これによると、低温通路３ａのシート２２は、高温通路３ｂのシート２３よりも下方に突出して積層されており、突出部３ｄと、厚みｔ，奥行きｄの長溝部３ｃとを形成している。
【００６１】
凝縮器３に流入した再生用空気７ｃは、凝縮されて凝縮水１９を生成して高温通路３ｂ内を成長しながら内壁面を伝って落下する。凝縮水１９が高温通路３ｂを構成するシート２３の下端面３０に達すると、凝縮水１９に表面張力が低温通路３ａを構成するシート２２の側面３２との間で働くことで、凝縮水１９は留まらずに、シート２２の側面３２を伝ってシート２２の下端面３１まで落下する。シート２２の下端面３１では、凝縮水１９に、側面３２及び下端面３１との間で表面張力が働くため落下しにくくなり、適当時間留まって大きな凝縮水１９ａとなり、ある程度の自重になってから、貯水部１０に落下する。
【００６２】
このように、凝縮水１９は、高温通路３ｂの下端面３０で留まることが無くなるため、高温通路３ｂを通った再生空気７ｃは、下端面３０と凝縮水１９ａとの隙間から流出し、高温通路３ｂを塞いで再生用空気７ｃの通過面積を減少させることなく常にほぼ最大に維持することが可能で、安定した凝縮効率を得ることができる。
【００６３】
次に、第６実施形態を図１２を参照して説明する。なお、従来例と同一の構成部材においては、同一の番号を付している。図１２において、除湿機１は、再生用空気循環式に構成されており、凝縮器３を通過した後の再生経路Ｂの一部分を、凝縮器３の貯水部１０の気圧が大気圧よりも高くなるように、他よりも細くして通気抵抗１３を形成している。これによって、貯水部１０の孔１０ａからスムーズに凝縮水２０が貯水槽２７に落下し、再生経路Ｂに凝縮水２０が大量に溜まることを防止している。
【００６４】
次に、第７実施形態を図１３を参照して説明する。なお、従来例と同一の構成部材においては、同一の番号を付している。図１３において、凝縮器３の貯水部１０と、除湿機１の窓部１８は、透明な材料で形成され、除湿機１外からユーザが貯水部１９の内部を見られるようになっている。これによると、除湿機１の運転開始後に凝縮水１９，２０が溜まっていくのをユーザが視認でき、運転効果を確認できるようになる。
【００６５】
次に、第８実施形態を説明する。先に述べたように、除湿機１の運転停止後の再生経路Ｂは、室温まで低下した際には、再生経路Ｂのほぼ全体が露点温度に達しており、除湿機１の運転停止後長時間放置しても乾燥しにくい。
【００６６】
これに対し、除湿機１を運転停止し、吸湿用の送風機４を停止させたときに、再生用の送風機６と再生用ヒータ５とを運転可能なスイッチを設け、ユーザによってこのスイッチが入れられるかまたは吸湿器の停止後自動的に、適当時間再生用の送風機６を運転し、ユーザによりまたは自動的に停止させるようにすることで、低温通路３ａ内の吸湿用空気１４ａは送風機４が停止していることから、停留し再生経路Ｂとの熱交換によって高温となるため、再生経路Ｂの凝縮が行われなくなる。
【００６７】
この状態で、送風機６と再生用ヒータ５の運転を続け、再生経路Ｂ内を乾燥させた後、送風機６と再生用ヒータ５の運転を停止させることで、除湿機内を乾燥させた状態で維持できる。
【００６８】
【発明の効果】
請求項１乃至請求項３の発明によると、除湿機外に放出される熱が低減され使用される部屋の室温上昇を低くすることが可能である。また、再生用ヒータの消費電力を低減可能である。
【００６９】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dehumidifier, and more particularly to a dry dehumidifier that performs dehumidification using a moisture absorbent.
[0002]
[Prior art]
As shown in FIG. 1, in the conventional dehumidifier, the air 14a for moisture absorption taken in from the outside of the dehumidifier 1 by the blower 4 is connected to one of two paths of the condenser 3 having two paths (hereinafter, referred to as a low-temperature path 3a). ), The interior is filled with a desiccant 26 such as silica gel, and the moisture is absorbed through one of the two air passages (hereinafter, referred to as the moisture absorbing portion 2a) of the rotary moisture absorber 2 having two divided air passages. A moisture absorption path A through which the dry air 14b is discharged to the outside of the dehumidifier 1 is configured.
[0003]
The regeneration air 7a introduced by the blower 6 from the outside of the dehumidifier 1 to regenerate the moisture absorbent 26 that has absorbed the moisture contained in the moisture absorption air 14a is heated by the regeneration heater 5 (7b). Then, the moisture absorbent 26 in the moisture absorber 2 is dried. The high-temperature regeneration air 7c containing water passes through the other passage (hereinafter, referred to as a high-temperature passage 3b) of the condenser 3 and exchanges heat with the moisture-absorbing air 14a passing through the low-temperature passage 3a to be cooled. And a regeneration path B that is condensed and discharged to the outside of the dehumidifier 1 is configured.
[0004]
Since the regeneration air 7c flowing into the condenser 3 is cooled, the water is condensed and falls as condensed water 19. At this time, since the smaller the amount of saturated water vapor is, the more water can be condensed, it is desirable to cool to as low a temperature as possible. Further, a water storage section 10 for receiving the condensed water 19 and a water storage tank 27 for receiving the condensed water 20 falling from the hole 10a formed in the water storage section 10 are provided so that the condensed water 19 does not accumulate in the regeneration path B. I have.
[0005]
FIG. 2 shows another conventional example, in which the regeneration path B is a regeneration air circulation type dehumidifier in which a closed circuit is circulated. The temperature of the regeneration air 7 d after passing through the condenser 3 is increased by the regeneration heater 5, passes through the regeneration section 2 b of the moisture absorber 2 to regenerate the moisture absorbent 26, and is condensed by the condenser 3. According to this configuration, since the high-humidity regeneration air 7d after condensation is not released to the outside of the dehumidifier 1, the dehumidifying effect is higher than in the above-described example.
[0006]
FIG. 3 shows details of the condenser 3. In the condenser 3, as shown in FIG. 3A, the low-temperature passage 3a of the moisture absorption path A and the high-temperature passage 3b of the regeneration path B are orthogonal to each other, and as shown in FIG. The sheets 22 and 23 divided into a number of passages are stacked and fixed alternately at a plurality of levels orthogonally to each other. The fixing surfaces 22a and 23a of the sheets 22 and 23 are formed as thin as possible and have a large contact area. The heat exchange between the moisture absorbing air 14a passing through the low temperature passage 3a and the regeneration air 7c passing through the high temperature passage 3b is performed. Improving efficiency.
[0007]
As shown in the cross-sectional view of the high-temperature passage 3b shown in FIG. 3C, the regeneration air 7c cooled by the heat exchange is condensed with water to form condensed water 19, and the condensed water 19 is owed to its own weight. Drops inside and is discharged.
[0008]
[Problems to be solved by the invention]
In the dehumidifier having such a configuration, heat of adsorption is generated when the moisture absorber 2 absorbs moisture from the air 14a, and heat of condensation is generated when the condenser 3 condenses the regeneration air 7c. I do. Further, in order to regenerate the moisture absorbent 26, the regeneration air 7b needs to be heated to about 140 ° C. or higher, so that the regeneration heater 5 is provided with the regeneration air 7b having the air volume determined by the blower 6. Requires power to raise the temperature.
[0009]
The residual heat generated by the regeneration heater 5 when the temperature of the regeneration air 7b rises is released from the dehumidifier 1 together with the above-mentioned heat of adsorption and heat of condensation, and raises the room temperature of the room in which it is used. It becomes a factor to give. Further, since the energy of the residual heat is excessively consumed by the regeneration heater 5, the power consumption of the dehumidifier 1 is increased.
[0010]
Further, the dry type dehumidifier has a disadvantage that it is quieter but has a larger shape than a compressor type dehumidifier.
[0011]
As shown in FIG. 3 (c), the condensed water 19 that has grown and propagated along the wall surface in the high-temperature passage 3b is dropped on the lower end surface 30 of the condenser 3 by a surface tension to a certain weight. Stayed without falling, and became a large water droplet 19a, blocking the high-temperature passage 3b.
[0012]
The high-temperature passage 3b is partially blocked by the water droplets 19a, so that the passage area of the regeneration air 7c is reduced and the area for heat exchange is reduced, and the passage area is further reduced. Is constant, the speed at which the regeneration air 7c passes through the condenser 3 is increased, which is a factor of deteriorating the condensation efficiency.
[0013]
In the regeneration air circulating dehumidifier, the hole 10a formed in the water reservoir 10 of the condenser 3 has a minimum size so that the regeneration air 7d does not leak from the closed regeneration path B as much as possible. It is open to. However, in the regeneration path B, since the high-temperature passage 3b of the condenser 3 has a thin tubular shape, the ventilation resistance is the highest, and the pressure of the regeneration air 7d after passing through the condenser 3 is lower than the atmospheric pressure, and This makes it difficult for the condensed water 19 to be discharged from 10a, thereby causing the condensed water 19 to accumulate in the regeneration path B.
[0014]
Further, when the dehumidifier 1 is operated, it is difficult for the user to confirm the dehumidifying effect because the humidity is less sensible than the temperature.
[0015]
Further, the regeneration path B is in a high humidity state, and when the operation of the dehumidifier 1 is stopped and the regeneration path B drops to room temperature, almost the entire regeneration path B has reached the dew point temperature. Since the regeneration path B is constituted by a narrow path (for example, 1/10 of the moisture absorption path A) in order to reduce the discharge of the high humidity regeneration air 7d, the regeneration path B is left for a long time after the operation of the dehumidifier 1 is stopped. However, it is difficult to dry, and there are problems such as generation of mold, propagation of various bacteria, and corrosion of metal parts.

An object of the present invention is to provide a dehumidifier that reduces heat released to the outside and consumes less power.

Another object of the present invention is to provide a dehumidifier having a small size and excellent cost performance.

BEST MODE FOR CARRYING OUT THE INVENTION
A first embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a configuration diagram of the first embodiment, and FIG. 5 is a schematic diagram illustrating a portion of the moisture absorber 2. Note that the same components as those of the conventional example are denoted by the same reference numerals.
[0039]
In the drawing, the air path of the moisture absorber 2 is divided into a heat radiation area 2ba, a regeneration area 2bb, and a heat receiving area 2bc in order from the front in the rotation direction (arrow 24) of the moisture absorber 2. The regeneration air 7 b heated by the regeneration heater 5 passes through the regeneration section 2 bb of the regeneration section 2 a of the moisture absorber 2 to regenerate the moisture absorbent 26. Although the temperature of the regeneration air 7b2 that has passed through the regeneration section 2bb is lower than that of the regeneration air 7b, it is still in a high temperature state, so the moisture is absorbed again through the heat receiving section 2bc in the regeneration section 2b of the moisture absorber 2. The agent 26 is given residual heat. The moisture absorbent 26 in the preheated heat receiving area 2bc moves to the regeneration area 2bb as the moisture absorber 2 rotates in the direction of the arrow 24.
[0040]
The regeneration air 7c passing through the heat receiving area 2bc is cooled and condensed through the condenser 3, and the cooled regeneration air 7d passes through the heat radiation area 2ba of the moisture absorber 2. Since the moisture absorbent 26 heated in the regeneration section 2bb moves to the heat radiation area 2ba with the rotation of the moisture absorber 2, the regeneration air 7d is preheated from the moisture absorbent 26 and becomes regeneration air 7d2. The temperature is raised by the heater 5.
[0041]
According to this configuration, as shown in FIG. 5, a first heat recovery circuit D is formed in which the regeneration air 7d2 recovers the heat of the desiccant 26 via the heat radiation area 2ba and the regeneration area 2bb. Since the temperature of the regeneration air 7d2 is raised before it is heated by the regeneration heater 5, the heating energy of the regeneration heater 5 can be reduced.
[0042]
Further, the second heat recovery circuit E is formed, in which the moisture absorbent 26 in the heat receiving area 2bc recovers the preheating of the regeneration air 7b2 and passes it to the regeneration area 2bb, so that the moisture absorbent 26 is located in the regeneration area. Since the temperature is raised in advance, the heating energy of the regeneration heater 5 for raising the temperature of the regeneration air 7b to a temperature required for regeneration of the moisture absorbent 26 can be reduced.
[0043]
In FIG. 4, although the regeneration path B is a closed circuit circulating, the regeneration air 7d entering the heat radiation area 2ba is taken in from the outside of the dehumidifier 1, and the regeneration air 7d passing through the condenser 3 is supplied to the dehumidifier 1 The same effect can be obtained with an open circuit that discharges to the outside.
[0044]
Next, a second embodiment will be described with reference to FIGS. FIG. 6 is a configuration diagram of the second embodiment, and FIG. 7 is a schematic diagram illustrating portions of the moisture absorber 2 and the heat exchanger 8. Note that the same components as those of the conventional example are denoted by the same reference numerals.
[0045]
In the figure, a heat exchanger 8 formed from the regeneration section 2b of the moisture absorber 2 to a part of the moisture absorption section 2a is arranged adjacent to the moisture absorber 2 and the regeneration air heated by the regeneration heater 5 is heated. 7 b is sent to the condenser 3 through the regeneration path B 1 in the heat exchanger 8 after regenerating the desiccant 26 through the regeneration section 2 b of the moisture absorber 2. The heat exchanger 8 is formed of a material having a high heat conductivity, and the regeneration air 7 b in a still high temperature state that has passed through the moisture absorber 2 gives residual heat to the heat exchanger 8.
[0046]
The moisture-absorbing air 14c passing through the moisture-absorbing path A2 branched from the moisture-absorbing path A passes through the moisture-absorbing path A1 adjacent to the regeneration path B1 in the heat exchanger 8, and is given conduction heat from the regeneration path B1. Is preheated to the desiccant 26 through the heat receiving part 2c located in the rotation direction (arrow 24) adjacent to the regenerating part 2b, and the desiccant 26 in the heat receiving part 2c moves to the regenerating part 2b by rotation. . The moisture absorbing air 14 d that has passed through the moisture absorber 2 returns to the moisture absorption path A because the moisture has been removed by the moisture absorbent 26, and is discharged outside the dehumidifier 1.
[0047]
According to this configuration, the recovery circuit F that recovers the residual heat of the heated regeneration air 7b via the heat exchanger 8 and the moisture absorption air 7b is formed. , The heating energy of the regeneration heater 5 for raising the temperature of the regeneration air 7b to a temperature required for regeneration of the moisture absorbent 26 can be reduced.
[0048]
Although FIG. 6 shows a configuration in which the moisture absorption path A2 is branched from the moisture absorption path A, if the moisture absorption path A is configured to partially extend to the moisture absorption path A1 in the heat exchanger 8, the moisture absorption path A2 Similar effects can be expected without branching A2.
[0049]
Next, a third embodiment will be described with reference to FIGS. FIG. 8 is a configuration diagram of the third embodiment, and FIG. 9 is a schematic diagram illustrating portions of the moisture absorber 2 and the rotary heat exchanger 9. Note that the same components as those of the conventional example are denoted by the same reference numerals.
[0050]
In the same figure, a rotary heat exchanger 9 is arranged at a position adjacent to the moisture absorber 2, and the regeneration air 7 b heated by the regeneration heater 5 passes through the regeneration section 2 b of the moisture absorber 2 and absorbs moisture. After regenerating 26, it is sent to the condenser 3 through the heat receiving section 9a in the heat exchanger 9. The high-temperature regeneration air 7b that has passed through the moisture absorber 2 gives residual heat to the heat exchanger 9.
[0051]
The moisture-absorbing air 14c passing through the moisture-absorbing path A2 branched from the moisture-absorbing path A passes through the heat-radiating section 9b adjacent to the heat-receiving section 9a in the heat exchanger 9. Since the desiccant 26 in the heat receiving part 9a of the heat exchanger 9 is moved to the heat radiating part 9b by the rotation of the heat exchanger 9 in the direction of the arrow 25, the moisture absorbing air 14c generates heat from the heat radiating part 9b of the heat exchanger 9. , And preheats the hygroscopic agent 26 through the heat receiving portion 2c of the moisture absorber 2 located on the rear side in the rotational direction (arrow 24) adjacent to the regenerating portion 2a of the moisture absorber 2 so that the heat absorbing portion 26 of the moisture absorber 2 is heated. The moisture absorbent 26 in 2c moves to the reproducing unit 2b by rotation in the direction of arrow 24. The moisture absorbing air 14 d that has passed through the moisture absorber 2 returns to the moisture absorption path A because the moisture has been removed by the moisture absorbent 26, and is discharged outside the dehumidifier 1.
[0052]
According to this configuration, the heat recovery circuit G that recovers the residual heat of the heated regeneration air 7b via the heat exchanger 9 and the moisture absorption air 7b is formed, whereby the moisture absorption agent 26 is regenerated. Since the temperature is raised before being located in the zone, the heating energy of the regeneration heater 5 for raising the temperature of the regeneration air 7b to a temperature necessary for regeneration of the moisture absorbent 26 can be reduced.
[0053]
Although FIG. 8 shows a configuration in which the moisture absorption path A2 is branched from the moisture absorption path A, if the moisture absorption path A is configured to partially extend to the heat radiating portion 9a in the heat exchanger 9, the moisture absorption path A2 will be described. Similar effects can be expected without branching A2.
[0054]
According to the above-described first, second and third embodiments, since the regenerating air 7 b heated by the regenerating heater 5 and the residual heat of the desiccant 26 are recovered, the amount of heat released outside the dehumidifier 1 is reduced. In addition to the reduction, the heating energy required for the regeneration heater 5 to perform heating is reduced, and the power consumption of the regeneration heater 5 can be reduced.
[0055]
Note that, in the second and third embodiments, the heat exchanger 8 and the heat exchanger 9 do not necessarily need to be adjacent to the moisture absorber 2, and the same effects can be obtained even if they are configured at distant positions. However, by arranging them as close as possible, the regeneration path B and the moisture absorption path A2 between the heat exchangers 8, 9 and the moisture absorber 2 can be shortened, and the amount of heat radiation from the regeneration path B and the moisture absorption path A2 is reduced. It is desirable because it can be done.
[0056]
In addition, in the second and third embodiments, the regeneration path B and the moisture absorption path A2 are counterflow, but need not necessarily be counterflow, and can be configured with parallel flow as shown in FIG. Although it is possible to obtain the effect, the counter flow makes it possible to shorten the regeneration path B and the moisture absorption path A2 between the heat exchangers 8 and 9 and the moisture absorber 2, and the regeneration path B and the moisture absorption path A2 This is desirable because the amount of heat radiation from the surface can be reduced.
[0057]
Further, in the third embodiment, the rotation directions of the heat exchanger 9 and the moisture absorber 2 are set in opposite directions. However, it is not always necessary to set the rotation directions in opposite directions, and as shown in FIG. Although it is possible to obtain the effect, the reverse direction can shorten the regeneration path B and the moisture absorption path A2 between the heat exchanger 9 and the moisture absorber 2, and the direction from the regeneration path B and the moisture absorption path A2 can be shortened. This is desirable because the amount of heat radiation can be reduced.
[0058]
Next, a fourth embodiment will be described with reference to FIG. Note that the same components as those of the conventional example are denoted by the same reference numerals. In FIG. 10, the regeneration air 7d that has passed through the condenser 3 joins the upstream side of the moisture absorber 2 in the moisture absorption path A, and the moisture is absorbed by the moisture absorption section 2a of the moisture absorber 2 together with the moisture absorption air 14a. Released outside.
[0059]
According to this configuration, after the condensation, the regeneration air 7d having a relative humidity of about 100% is joined to the moisture absorption path A to increase the moisture concentration of the moisture absorption air 14a, and the moisture contained in the regeneration air 7d also absorbs moisture. Since moisture is absorbed by the device 2, the dehumidifying effect can be improved, so that the size of the device 2 can be reduced.
[0060]
Next, a fifth embodiment will be described with reference to FIG. The same components as those of FIG. 3 described above are denoted by the same reference numerals. In FIG. 11, (a) shows a perspective view of the condenser 3 in the fifth embodiment, and (b) shows a longitudinal sectional view of the high temperature passage 3b. According to this, the sheet 22 of the low-temperature passage 3a is laminated so as to protrude below the sheet 23 of the high-temperature passage 3b, and forms a protruding portion 3d and a long groove 3c having a thickness t and a depth d.
[0061]
The regeneration air 7c that has flowed into the condenser 3 is condensed to generate condensed water 19 and drops along the inner wall surface while growing in the high-temperature passage 3b. When the condensed water 19 reaches the lower end surface 30 of the sheet 23 forming the high-temperature passage 3b, the surface tension of the condensed water 19 acts between the condensed water 19 and the side surface 32 of the sheet 22 forming the low-temperature passage 3a. Instead of stopping, it falls along the side surface 32 of the sheet 22 to the lower end surface 31 of the sheet 22. At the lower end surface 31 of the sheet 22, the condensed water 19 is hardly dropped due to surface tension acting between the side surface 32 and the lower end surface 31. After a suitable time, the condensed water 19 becomes large condensed water 19a. , Falls into the water storage unit 10.
[0062]
As described above, since the condensed water 19 does not stay at the lower end surface 30 of the high-temperature passage 3b, the regenerated air 7c passing through the high-temperature passage 3b flows out of the gap between the lower end surface 30 and the condensed water 19a, and the high-temperature passage It is possible to keep almost the maximum without reducing the passage area of the regeneration air 7c by closing 3b, so that stable condensation efficiency can be obtained.
[0063]
Next, a sixth embodiment will be described with reference to FIG. Note that the same components as those of the conventional example are denoted by the same reference numerals. In FIG. 12, the dehumidifier 1 is configured as a regeneration air circulation system. The dehumidifier 1 partially regenerates the regeneration path B after passing through the condenser 3 and the pressure of the water storage unit 10 of the condenser 3 is higher than the atmospheric pressure. Thus, the ventilation resistance 13 is formed to be thinner than the others. This prevents the condensed water 20 from dropping into the water storage tank 27 smoothly from the hole 10a of the water storage unit 10, and prevents a large amount of the condensed water 20 from accumulating in the regeneration path B.
[0064]
Next, a seventh embodiment will be described with reference to FIG. Note that the same components as those of the conventional example are denoted by the same reference numerals. In FIG. 13, the water reservoir 10 of the condenser 3 and the window 18 of the dehumidifier 1 are formed of a transparent material so that a user can see the inside of the water reservoir 19 from outside the dehumidifier 1. According to this, the user can visually recognize the accumulation of the condensed water 19 and 20 after the start of the operation of the dehumidifier 1 and can confirm the operation effect.
[0065]
Next, an eighth embodiment will be described. As described above, when the regeneration path B after the operation of the dehumidifier 1 has been stopped has dropped to room temperature, almost the entire regeneration path B has reached the dew point temperature, and the length of time after the operation of the dehumidifier 1 has been stopped is long. Hard to dry even if left for a long time.
[0066]
On the other hand, when the operation of the dehumidifier 1 is stopped and the blower 4 for absorbing moisture is stopped, a switch capable of operating the blower 6 for regeneration and the heater 5 for regeneration is provided, and this switch is turned on by the user. By automatically operating the blower 6 for regeneration for an appropriate time after the stop of the humidifier or by stopping the blower 4 by the user or automatically, the blower 4 stops the humidifying air 14a in the low-temperature passage 3a. Therefore, the temperature of the regeneration path B becomes high due to heat exchange with the regeneration path B, so that the regeneration path B is not condensed.
[0067]
In this state, the operation of the blower 6 and the regeneration heater 5 is continued, and after the inside of the regeneration path B is dried, the operation of the blower 6 and the regeneration heater 5 is stopped, so that the inside of the dehumidifier is kept dry. it can.
[0068]

[0070]
According to the invention of claim 5, since the effective area of the condenser outlet in the regeneration path is always constant, it is possible to obtain a stable condensation efficiency.
[0071]
According to the invention of claim 6, in the regeneration air circulation type dehumidifier, the pressure at the outlet of the condenser in the regeneration path can be maintained higher than the atmospheric pressure, so that the condensed water can be discharged smoothly.
[0072]
According to the invention of claim 7, the user can visually recognize the dehumidifying effect.
[0073]
According to the invention of claim 8, since the inside of the regeneration path can be maintained in a dry state, it is possible to prevent the occurrence of mold, propagation of various bacteria, corrosion of metal parts, and the like.
