Description

【０００１】
【発明の属する技術分野】
本発明は、室内空気を除湿する除湿機に関するものである。
【０００２】
【従来の技術】
従来、この種の除湿機は、図６および図７に示すものが一般的であった。
【０００３】
以下、その除湿機について図を参照しながら説明する。
【０００４】
図に示すように、本体１０１内部に、駆動モーター１０２により回転される空気中の水分を吸脱着するための除湿ローター１０３と、この除湿ローター１０３を加熱する発熱ユニット１０４を設け、発熱ユニット１０４は加熱ヒーター１０４ａを備えている。加熱ヒーター１０４ａで加熱された除湿ローター１０３は高温高湿空気を放出し、この高温高湿空気は熱交換器１０５と、サブ熱交換器１０５ａを通るときに結露水を生成し、この結露水は排水タンク１１に流れ込む。除湿ローター１０３、発熱手段１０４、熱交換器１０５、サブ熱交換器１０５ａを支持する仕切り板（図示せず）を設けている。また、除湿ローター１０３から熱交換器１０５、サブ熱交換器１０５ａ、発熱ユニット１０４に戻る閉循環経路ａに空気を通風する第１の送風ファン１０６を設け、本体１０１内に室内空気を吸込み、乾燥空気を排出する通風路に第２の送風ファン１０７を設けている。前記発熱ユニット１０４内は送風領域１０４ｃと加熱領域１０４ｄがあり、加熱ヒーター１０４ａと外枠１０４ｂの間に複数の穴を有した遮蔽板１０４ｅを設けることにより、加熱ヒーター１０４ａによる周辺部品への輻射熱を抑制するとともに、送風領域１０４ｃと加熱領域１０４ｄの通過風量を適正に調節する役目をしている。また、前記発熱ユニット１０４の金属製内枠１０４ｆは回転する除湿ローター１０３の金属製除湿ローター保持枠１０３ａとの隙間を０．１ｍｍ〜０．５ｍｍの隙間となるよう設置され、閉循環経路ａからの空気漏れを防止している。また、吹出口１０９近傍に衣類乾燥時に衣類を早く乾燥させるためのヒーター１１０を設けた構成となっている。
【０００５】
【発明が解決しようとする課題】
このような従来の除湿機では、遮蔽板に複数の穴が開いているため、穴部分から輻射熱が漏れて熱効率が低下し、また、遮蔽板を加熱ヒーターと別に設ける必要があり、部品点数が増えるという課題があり、部品点数を減らし簡単な構造で輻射熱の漏れを防止でき、効率良く除湿ローターに輻射熱を供給することが要求されている。
【０００６】
また、遮蔽板自身が熱を吸収して、間接的に熱が周囲に分散して除湿ローターへの熱効率が低下するという課題があり、遮蔽板の熱吸収を減らして熱効率を上げ、加熱ヒーターの発熱量を有効に利用するとともに周辺部品への熱影響を低減することが要求されている。
また、遮蔽板と外枠との隙間に風が漏れ、加熱ヒーターに均一に送風されないという課題があり、輻射熱を遮蔽しながら通風の抵抗を減らして、加熱ヒーターに均一に送風することが要求されている。
【０００７】
本発明は、このような従来の課題を解決するものであり、加熱ヒーターの輻射熱が周辺部品に漏れるのを防止し、また、加熱ヒーターの輻射熱を有効に使い除湿ローターへの加熱量を増やし、また、加熱ヒーターへの通風を均一にして除湿ローターの水分を効率良く放出させることができる除湿機を提供することを目的としている。
【００１２】
【課題を解決するための手段】
本発明の除湿機は上記目的を達成するために、本体内部に、空気中の水分を吸着する除湿ローターと、前記除湿ローターを回転させる駆動手段と、前記除湿ローターから水分を放出させる発熱手段と、この発熱手段により前記除湿ローターから放出された高温高湿空気を結露させる熱交換器と、前記熱交換器を通過した高温高湿空気を上記発熱手段に戻すダクトと、前記発熱手段、除湿ローター、熱交換器、ダクトの順序に通過する空気を閉循環させる第１送風手段と、前記熱交換器を冷却するとともに前記除湿ローターに水分を吸着させて吹出口から乾燥空気を送出する第２送風手段を有し、前記発熱手段は、内部に設けた遮蔽板および加熱ヒーターと、前記遮蔽板および加熱ヒーターの外枠とからなり、前記加熱ヒーターと前記外枠との間に前記加熱ヒーター前面を覆う前記遮蔽板を設け、前記外枠と前記遮蔽板の間に空気層を設け、前記発熱手段内に設けた前記遮蔽板の前記加熱ヒーター側の表面は光沢性を有し、前記発熱手段内に設けた前記遮蔽板に傾斜面を設け、この傾斜面を空気層側に傾斜させるとともに、前記発熱手段の空気流入側に配置したものである。
【００１３】
本発明によれば、加熱ヒーターへの通風を均一にして除湿ローターの水分を効率良く放出され、加熱ヒーターの輻射熱が周辺部品に漏れるのを防止でき、加熱ヒーターの輻射熱を有効に使い除湿ローターへの加熱量を増やした除湿機が得られる。
【００１６】
本発明は、本体内部に、空気中の水分を吸着する除湿ローターと、前記除湿ローターを回転させる駆動手段と、前記除湿ローターから水分を放出させる発熱手段と、この発熱手段により前記除湿ローターから放出された高温高湿空気を結露させる熱交換器と、前記熱交換器を通過した高温高湿空気を上記発熱手段に戻すダクトと、前記発熱手段、除湿ローター、熱交換器、ダクトの順序に通過する空気を閉循環させる第１送風手段と、前記熱交換器を冷却するとともに前記除湿ローターに水分を吸着させて吹出口から乾燥空気を送出する第２送風手段を有し、前記発熱手段は、内部に設けた遮蔽板および加熱ヒーターと、前記遮蔽板および加熱ヒーターの外枠とからなり、前記加熱ヒーターと前記外枠との間に前記加熱ヒーター前面を覆う前記遮蔽板を設け、前記外枠と前記遮蔽板の間に空気層を設け、前記発熱手段内に設けた前記遮蔽板の前記加熱ヒーター側の表面は光沢性を有し、前記発熱手段内に設けた前記遮蔽板に傾斜面を設け、この傾斜面を空気層側に傾斜させるとともに、前記発熱手段の空気流入側に配置したことにより、傾斜面で加熱ヒーターへの送風を整流でき、加熱ヒーターを通過する風速を均一にして温風温度を均等化できるという作用を有し、遮蔽板で加熱ヒーターの直接的な輻射熱を遮り、遮蔽板と外枠との間の空気層で間接的な輻射熱を遮断でき、加熱ヒーターの直接的な輻射熱を除湿ローターに向けて反射させることができるという作用を有する。
【００１７】
【実施例】
（参考例１）
図１および図２に示すように、本体１内には空気中の水分を吸着する除湿ローター２と、前記除湿ローターを回転させる駆動手段３と、前記除湿ローターから水分を放出させる発熱ユニット４と、この発熱ユニット４により前記除湿ローター２から放出された高温高湿空気を結露させる熱交換器５と、前記熱交換器を通過した高温高湿空気を上記発熱手段に戻すダクト５ａを内蔵している。前記発熱ユニット４、除湿ローター２、熱交換器５、ダクト５ａは仕切り板（図示せず）によって支持され、本体１内部に固定されている。第１送風手段７により発熱ユニット４、除湿ローター２、熱交換器５、ダクト５ａの順序に通過する空気を閉循環させる閉循環風路ａと、第２送風手段８により熱交換器５を冷却するとともに除湿ローター２に水分を吸着させて吹出口から乾燥空気を送出する風路ｂを形成している。なお閉循環風路ａにおいて、熱交換器５内で結露を起こして生じた結露水は排水タンク９に貯えるようになっている。
【００１８】
また、発熱ユニット４の加熱ヒーター４ａと外枠４ｂとの間には加熱ヒーター４ａ前面を覆うように遮蔽板４ｃを設け、外枠４ｂと遮蔽板４ｃの間に空気層４ｄを設けた構成となっている。
【００１９】
上記構成において、発熱ユニット４の加熱ヒーター４ａからの直接的な輻射熱は遮蔽板４ｃによって遮られ、また、間接的な輻射熱は遮蔽板４ｃと外枠４ｂの間に設けた空気層４ｄで断熱され、外枠４ｂを介して発熱ユニット４外部へ熱が拡散することを防止できる。すなわち加熱ヒーター４ａの発熱容量を低減することができるとともに、熱ロスのない効率良い除湿運転を行うことができる。
【００２０】
（参考例２）
本参考例以降において、参考例１と同一構成のものは同一番号を付して詳しい説明を省略する。
【００２１】
発熱ユニット４内に設けた遮蔽板４ｃの加熱ヒーター４ａ側の表面は、鏡面仕上げなど光沢性を有する表面処理が施されている。
【００２２】
上記構成において、発熱ユニット４の加熱ヒーター４ａからの直接的な輻射熱は遮蔽板４ｃによって遮られ、また、間接的な輻射熱は遮蔽板４ｃと外枠４ｂの間に設けた空気の層４ｄで断熱され、外枠４ｂを介して発熱ユニット４外部へ熱が拡散することを防止できる。さらに加熱ヒーター４ａからの直接的な輻射熱を遮蔽板４ｃが除湿ローター２側に反射させて熱効率を向上することができるとともに、周辺に逸散する熱ロスを軽減することができる。
【００２３】
したがって、除湿ローター２を従来と同一温度まで加熱する場合は、加熱ヒーター４ａの入力を低減でき、省エネルギーで効率良く除湿運転を行うことができる。
【００２４】
（実施例１）
図３に示すように、発熱ユニット４内に設けた遮蔽板４ｃの空気流入側に傾斜面４ｅを設け、遮蔽板４ｃと外枠４ｂの間には空気層４ｄを介在させた構成としている。
【００２５】
上記構成において、発熱ユニット４の加熱ヒーター４ａからの直接的な輻射熱は遮蔽板４ｃによって遮られ、また、間接的な輻射熱は遮蔽板４ｃと外枠４ｂの間に設けた空気層４ｄで断熱され、外枠４ｂを介して発熱ユニット４外部へ熱が拡散することを防止できる。さらに傾斜面４ｅが加熱ヒーター４ａ内部へ向かう空気流れを整流して、風速分布を略均一にできるので、加熱ヒーター４ａを通過するときの熱交換効率が改善され、効率良く除湿運転を行うことができる。
【００２６】
（参考例３）
図４に示すように発熱ユニット４の内枠１０に凸部１０ａを設け、この凸部１０ａを、除湿ローター２の表面と除湿ローター保持枠１１の凸部１１ａに沿うように微少な距離（０．５ｍｍ以下）を隔てて突出して配設した構成としている。
【００２７】
上記構成において、発熱ユニット４の内枠１０と除湿ローター保持枠１１の間には０．５ｍｍ以下の隙間が段状に形成され、加熱ヒーター４ａで加熱された熱風の漏れを極めて少なく抑えることができ、除湿性能を向上することができる。
【００２８】
（参考例４）
図４に示すように、発熱ユニット４の内枠１０側の除湿ローター保持枠１１を耐熱性合成樹脂製にしたもので、金属性に比べて厚みがやや大きくなっている。
【００２９】
上記構成において、仕切り板６の反り、歪み等で発熱ユニット４の金属製の内枠１０と樹脂製の除湿ローター保持枠１１が接触した場合は、合成樹脂の表面と金属の接触となるが、金属同士が擦れ合うことがないので、メッキ剥がれや擦れ音の発生がなく、長期間安定して使用することができる。
【００３０】
（参考例５）
図５に示すように第２送風手段８と吹出口１２との間に衣類乾燥用の発熱部１３を有し、前記発熱部１３の上面を開口率が小なる金属メッシュ１３ａで覆った構成としている。上記構成において、開口率が小なる金属メッシュ１３ａが衣類乾燥用の発熱部内部を流れる風を整流し風速分布を均一にできるので、金属メッシュ１３ａを通過して吹出口１２から吹出される温風温度を均一にでき、効率良く衣類を乾燥することができる。
【００３３】
【発明の効果】
以上の実施例から明らかなように、本発明によれば本体内部に、空気中の水分を吸着する除湿ローターと、前記除湿ローターを回転させる駆動手段と、前記除湿ローターから水分を放出させる発熱手段と、この発熱手段により前記除湿ローターから放出された高温高湿空気を結露させる熱交換器と、前記熱交換器を通過した高温高湿空気を上記発熱手段に戻すダクトと、前記発熱手段、除湿ローター、熱交換器、ダクトの順序に通過する空気を閉循環させる第１送風手段と、前記熱交換器を冷却するとともに前記除湿ローターに水分を吸着させて吹出口から乾燥空気を送出する第２送風手段を有し、前記発熱手段は、内部に設けた遮蔽板および加熱ヒーターと、前記遮蔽板および加熱ヒーターの外枠とからなり、前記加熱ヒーターと前記外枠との間に前記加熱ヒーター前面を覆う前記遮蔽板を設け、前記外枠と前記遮蔽板の間に空気層を設け、前記発熱手段内に設けた前記遮蔽板の前記加熱ヒーター側の表面は光沢性を有し、前記発熱手段内に設けた前記遮蔽板に傾斜面を設け、この傾斜面を空気層側に傾斜させるとともに、前記発熱手段の空気流入側に配置したことにより、傾斜面が加熱ヒーター内部への送風を整流し、除湿ローターへ供給される温風の温度分布および風速分布を均一化できるので、高い除湿能力を安定して維持でき、加熱ヒーターからの直接的な輻射熱は遮蔽板によって遮られ、間接的な輻射熱は遮蔽板と外枠の間に設けた空気の層で断熱され、外枠を介して発熱ユニット外部へ熱が拡散することを防止でき、加熱ヒーターの入力を低減でき、加熱ヒーターからの直接的な輻射熱を遮蔽板が除湿ローター側に反射させて熱効率を向上することができるため、除湿ローターから効率良く水分を脱離することのできる効果のある除湿機を提供できる。

(Reference Example 4 )
As shown in FIG. 4, the dehumidifying rotor holding frame 11 on the inner frame 10 side of the heat generating unit 4 is made of heat-resistant synthetic resin, and the thickness is slightly larger than that of metal.
[0029]
In the above configuration, when the metal inner frame 10 of the heat generating unit 4 and the resin-made dehumidifying rotor holding frame 11 come into contact with each other due to warping or distortion of the partition plate 6, the surface of the synthetic resin is in contact with the metal. Since metals do not rub against each other, there is no occurrence of peeling of plating or rubbing noise, and the metal can be used stably for a long time.
[0030]
(Reference Example 5 )
As shown in FIG. 5, it has a heat generating part 13 for drying clothes between the second air blowing means 8 and the air outlet 12, and the upper surface of the heat generating part 13 is covered with a metal mesh 13a having a small opening ratio. Yes. In the above configuration, the metal mesh 13a having a small opening ratio can rectify the wind flowing inside the heat generating part for drying clothes and make the wind speed distribution uniform, so that the warm air blown from the outlet 12 through the metal mesh 13a. The temperature can be made uniform and the clothes can be efficiently dried.
