Abstract
Description
図1および図2を参照して、本発明に基づく実施の形態1における除湿機100について説明する。図1は、除湿機100の構造を概念的に示した平面図であり、図2は図1の中央線II-IIで切断した内部構造を示す断面図である。実際の各部の寸法比や位置関係はこのとおりとは限らない。 (Embodiment 1)
With reference to FIG. 1 and FIG. 2, the
実施の形態1では、高分子ゲル吸湿材料をポリ-N-イソプロピルアクリルアミドとして説明をしたが、同様に温度に応答して吸湿をする第1の状態と放湿をする第2の状態との間で相転移を行う高分子ゲル材料が他にも知られているので、前者とは動作条件が異なるものの除湿機としての応用が可能である。例えば、ポリエチレンオキシド、ポリメチルビニルエーテルや、オキシエチレン鎖を有するビニルエーテルやポリメタクリレート、ポリヒドロキシブチルビニルエーテルおよびこれらの誘導体などがある。 (Embodiment 2)
In the first embodiment, the polymer gel moisture-absorbing material has been described as poly-N-isopropylacrylamide, but similarly, between the first state where moisture is absorbed in response to temperature and the second state where moisture is released. Since other polymer gel materials that undergo phase transition are known, they can be applied as dehumidifiers although their operating conditions differ from those of the former. For example, there are polyethylene oxide, polymethyl vinyl ether, vinyl ether and polymethacrylate having an oxyethylene chain, polyhydroxybutyl vinyl ether, and derivatives thereof.
実施の形態1では、ロータ1を通過した後の高温空気6cの温度が吸湿材2の相転移温度約40℃以上であることが条件であったが、このような不具合に対応するため、本実施形態では上端面近傍の吸湿材の相転移温度と下端面近傍の吸湿材の相転移温度を異ならせることとした。つまり、ロータの上端面近傍の吸湿材の相転移温度よりも、下端面近傍の吸湿材の相転移温度を低くなるように構成する。好ましくは通気構造を通過する高温空気の温度変化に合わせた相転移温度に調整するのが良い。除湿機構造としては実施の形態1と同じものとなる。以下の説明において、図中の符号は実施の形態1と同じものは同じ番号を附し説明は省く。 (Embodiment 3)
In the first embodiment, the condition is that the temperature of the high-
実施の形態3では、ロータの厚さ方向に数種類の吸湿材を相転移温度が低くなる順に担持する構造について述べたが、本実施形態ではロータの半径方向に異なる相転移温度を有する吸湿材を担持させる場合について説明する。 (Embodiment 4)
In the third embodiment, the structure in which several types of moisture absorbing materials are supported in the thickness direction of the rotor in order of decreasing phase transition temperature has been described. However, in this embodiment, moisture absorbing materials having different phase transition temperatures in the radial direction of the rotor are used. The case where it carries is demonstrated.
ロータ41の基材44が構成する通気構造は、図8に示すように断面が三角形であっても、その他の多角形であっても特に制限するものではない。また、吸湿材を粒状に成型して、円筒形で中心軸方向の両端面を通気構造とした筐体に詰めた構造、網状立体構造を有する基材に吸湿材を担持させた構造、など従来から知られる形状であってもよい。 (Embodiment 5)
The ventilation structure formed by the
実施の形態4または実施の形態5に示したような相転移温度の異なる吸湿材を複数使用する場合に、より好ましい刺激付与部61の構造について図9に示す。本実施形態では、実施の形態4で使用したロータ41を使用する除湿機として説明を行う。 (Embodiment 6)
FIG. 9 shows a more preferable structure of the
実施の形態6では、相転移温度が異なる複数の吸湿材をロータの半径方向に配設したものとして説明を行ったが、実施の形態3で使用した様に相転移温度が異なる複数の吸湿材をロータの厚さ方向に配設したものを使用しても同じように動作させることが出来る。除湿機の構成は図10、図11にロータ構造を説明する模式図を示す。 (Embodiment 7)
In the sixth embodiment, a description has been given assuming that a plurality of hygroscopic materials having different phase transition temperatures are arranged in the radial direction of the rotor. However, as used in the third embodiment, a plurality of hygroscopic materials having different phase transition temperatures are used. It is possible to operate in the same manner even if a rotor disposed in the thickness direction of the rotor is used. The structure of a dehumidifier shows the schematic diagram explaining a rotor structure in FIG. 10, FIG.
実施の形態1~7については、使用する吸湿材が温度応答性を有する高分子ゲル吸湿材料であるとして説明を行ったが、温度応答性以外の特性を有する高分子ゲル吸湿材料も使用できる。例えば、電磁波応答性を有する高分子ゲル吸湿材料などが除湿機には使用できる。電磁波応答性を有する高分子ゲル吸湿材料は、前述した温度応答性を有する高分子ゲル吸湿材料に電磁波を吸収して発熱する物質を混合させることで実現できる。例えば、黒鉛やカーボングラファイト、カーボンナノチューブなどの炭素系物質や炭化チタン、炭化ジルコニウムなどの炭化物、黒化銀、酸化鉄などの金属酸化物や天然顔料、有機顔料など多くのものが利用できる。添加する電磁波吸収物質は、高分子ゲル吸湿材料が含んでいる水分に溶解せず、電気的にかい離せずイオン化しない物質が好ましい。 (Embodiment 8)
