Description

【0001】
【発明の属する技術分野】
本発明は、潮解性吸湿剤を用いて除湿を行う除湿器に関する。
【0002】
【従来の技術】
従来より、押し入れ内やタンス内の除湿を目的として、潮解性吸湿剤を使用する除湿器が広く利用されている。 このような除湿器としては、例えば容器本体を、潮解液の滴下孔を複数穿設した受皿によって上段空間部、下段空間部の2つの空間部に区分し、前記上段空間部に粉状、顆粒状または粒状などの塩化カルシウムや塩化マグネシウムなどの潮解性吸湿剤を詰め、前記下段空間部に外気中の水分に接触して吸湿して潮解した潮解液を貯溜する構造のものがあり、前記容器本体の開口部をフィルム状の透湿性を有して且つ非透水性を有する透湿・非透水性皮膜で覆うと共に、このフィルム状の透湿・非透水性皮膜に蓋を被せて保護する一方、この蓋に通気部を設けて湿気を含んだ外気が潮解性吸湿剤まで導かれる構成になっている。
【0003】
この除湿器では外気中の湿気は、蓋に設けた通気部を通過した後、透湿・非透水性皮膜を透過し、容器本体の上段空間部に詰められている潮解性吸湿剤に接触する。そして、外気中の湿気が潮解性吸湿剤に接触することにより、やがて潮解液が生じ、この潮解液が受皿に穿設されている滴下孔を通って容器本体の下段空間部に滴下して貯溜されていく。このときの潮解性吸湿剤の吸湿速度は、上段空間部に詰められている潮解性吸湿剤に接触する外気の割合によって決まるので、この除湿器では上部空間部に取り込まれる外気の割合が、容器本体の開口部の皮膜面積に依存し、この皮膜面積が大きくなればなるほど外気と潮解性吸湿剤との接触する割合が増大して吸湿速度が向上する。なお、上述のように構成した除湿器では、4日間で約25グラムの潮解液が得られ、8日間で約50グラムの潮解液を得られた。
【0004】
しかし、吸湿速度を向上させるために上述のように容器本体の開口部の皮膜面積を大きくするようにしたのでは、底面積の大きな容器本体になってしまうので、この容器本体を設置するために大きなスペースが必要になってしまう。また、容器本体の開口部を覆っているシート状の透湿・非透水性皮膜の厚み寸法が、数十μmから数百μmと薄く形成されているので、除湿器生産時や取扱い時、または輸送時などに透湿・非透水性皮膜を破くおそれがあり、万一、開口部を覆う透湿・非透水性皮膜が破れると、上段空間部に詰められていた潮解性吸湿剤が容器本体外部にこぼれ落ちてしまったり、下段空間部に貯溜されていた潮解液が流出して衣類、布団、家具などを汚染するおそれがあるので、取扱いが難しく、十分な注意を払わなければならなかった。
【0005】
また、上述記載のように吸湿速度が潮解性吸湿剤に接触する外気の割合に依存することから、潮解性吸湿剤に導く外気の割合を増大させるようにした除湿器が特開昭57−1072号公報や、実公平4−8985号公報に示されている。これら除湿器によれば、塩化ナトリウムなどの潮解性吸湿剤と外気との接触する割合を増大させるために、潮解性吸湿剤を多数の透孔を設けた容器本体の開口部の皮膜面積より大きくなるように略半球形状に形成したドーム型部材の内部に配置している。この除湿器では、表面積を大きく形成したドーム型部材の通気部からドーム型部材の内部に外気が進入して潮解性吸湿剤に接触して潮解液が生じ、この潮解液が容器本体内に貯溜されていくようになっている。
【0006】
さらに、実公昭61−10743号公報には潮解性吸湿剤を可撓性を有する追従性の高い半透膜で覆って半球形状に形成することによって、外気との接触する割合を大きくする一方、除湿器を転倒させてしまったときなどに、容器内に貯溜されていた潮解液が容器外に流出するのを防止した除湿器が示されている。この除湿器では湿気を含む外気が半透膜を通過して吸湿剤に接触して潮解液が生じ、この潮解液が流下して容器内に貯溜されていく。このとき、潮解性吸湿剤は外気中の湿気に接触して潮解していくことにより潮解性吸湿剤が減少して、初期状態の半球形状から徐々に変形していくが、半透膜が可撓性を有することから常に半透膜と吸湿剤との密着した状態が保持されて半透膜内の潮解性吸湿剤の吸湿効率を持続させている。
【0007】
【発明が解決しようとする課題】
しかしながら、上記特開昭57−1072号公報または実公平4−8985号公報に示されている除湿器では万一、容器本体内に潮解液が貯溜されている状態で、除湿器を転倒させてしまった場合、容器本体の上部に配置されている潮解性吸湿剤を収容しているドーム型や半球形状の部材に形成されている通気部から貯溜されていた潮解液が流れ出てしまうという問題があった。
【0008】
また、上記実公昭61−10743号公報に示されている除湿器は、円筒状の容器のフランジに複数の透孔を設けた多孔状底板を載せて容器の開口部を覆い、前記多孔状底板の上に吸湿剤を半球形状に盛り上げ、この吸湿剤の外表面を半透膜に密着させて覆うと共に、この半透膜の周辺を前記多孔状底板の周縁に接着し、さらに、前記半透膜の外周を半球形状の網蓋によってカバーし、この網蓋の周端部に多孔状底板の周縁をパッキンとして容器のフランジと脱着可能に密着し得る係止部を設けているので、部品点数が多くなることによって組立てが煩雑になるという問題があった。
【0009】
又、前記透湿・非透水性皮膜が半透膜で形成されているため組立て時に破損するおそれがあった。
【0010】
本発明は上記事情に鑑みてなされたものであり、外気と潮解性吸湿剤との接触する割合が大きく、除湿器転倒時に容器本体内に貯溜されている潮解液が流出することが無く、組立構造が簡単な除湿器を提供することを目的としている。
【0011】
【課題を解決するための手段】
本発明の除湿器は、潮解性吸湿剤が潮解した際の潮解液を貯溜する貯溜部を備える容器本体と、
前記潮解性吸湿剤を収納した通気性及び透水性を有する包装体を収容する空間部を内側に備えた立体形状で、外気を前記空間部に導く透湿性及び前記潮解液が外部に漏出することを防止する非透水性を有する部材で形成された可透湿部と、
前記潮解性吸湿剤を収納した前記包装体を前記可透湿部の前記空間部に配置収容する、前記潮解液が通過する透孔を複数設けた仕切部材と、
前記容器本体と前記可透湿部とを、この可透湿部と該容器体との間に前記仕切部材を配置させた状態で、一体的に密着させて固定する固定手段とを具備し、
前記可透湿部は凸型形状であって、可透湿部外表面の表面積を、前記容器本体の開口部の開口面積に対して110パーセントから250パーセントの範囲に設定している。
【0012】
また、前記可透湿部は、超高分子量ポリオレフィン粉末を焼結させて形成した多孔質構造体であって、
丸棒状の多孔質構造体を切断して得られた多孔質構造体円板シートを所定温度で所定時間加熱して、所定形状の金型で賦型した後、冷却して前記空間部を有する凸型形状を形成している。
【0013】
この構成によれば、潮解性吸湿剤を収納した包装体を収容する空間部を備える凸型形状の可透湿部が透湿性を有し、その外表面表面積が容器本体の開口部の開口面積に対して110パーセントから250パーセントの範囲に設定されているので、外気が可透湿部の空間部に多く取り込まれて包装体を通過して、この包装体内に収容された潮解性吸湿剤と外気との接触する割合が増大する。また、潮解性吸湿剤が包装体に収容されているので、可透湿部の空間部内に包装体を配置することによって潮解性吸湿剤の収納を容易に行えるので組立作業性が向上する。さらに、固定手段である固定部材によって可透湿部と、仕切部材と、容器本体とを密着させて一体的に固定しているので、除湿器が転倒してしまったときでも容器本体内に貯溜されている潮解液が外部に漏出しない。
【0014】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を説明する。
図1及び図2は本発明の一実施形態に係り、図1は除湿器の概略構成を説明する図、図2は除湿器の組立構成を説明する分解説明図である。
【0015】
図に示すように除湿器1は、外気中の湿気に接触して潮解することによって吸湿する潮解性吸湿剤2と、この潮解性吸湿剤2を収容する空間部3aを有する略半球形状の立体形状で後述する透湿・非透水性を有する部材で形成された可透湿部3と、前記潮解性吸湿剤2が外気中の湿気に接触して潮解した潮解液8を貯溜するための空間部である貯溜部4aを有する略円筒状の容器本体4とで主に構成されている。
【0016】
前記容器本体4は、潮解液が漏出しない構造体であれば部材は特に限定されるものではなく、この容器本体4の上端部には半径rの円形の本体開口部4bが形成されると共に、外周面に雄ねじ4cを形成した容器本体4の外周面から突出した上端凸部4dが形成されている。
【0017】
前記可透湿部3は、例えば略半球形状であり、前記容器本体4の半径rの円形の本体開口部4bに対向する可透湿部開口3bの開口面積に対して略半球外表面の外表面積の割合を180%などに設定して立体的な凸型形状に形成されている。このとき、前記可透湿部開口3bの開口面積に対して外表面積の割合を200%に設定して可透湿部3を半球形状の立体形状に形成すると、可透湿部開口3bの開口形状が円であることから、この円の面積がπrで表せ、球体の表面積が4πrで表せることから、外表面積が可透湿部開口3bの200%に設定された場合には、外表面積の値が2πrとなって、この外表面積がちょうど球体の表面積の半分に相当して、可透湿部3の形状が半球形状のドーム型になる。なお、この可透湿部3の可透湿部開口3bの外周には前記容器本体4の上端凸部4dに略同径に形成した縁部3cが形成されている。
【0018】
前記可透湿部3の空間部3a内に収容される潮解性吸湿剤2は、前記空間部3a内に容易に収容することが可能なように通気性及び透水性の高い不織布を袋状に形成した包装体5内に収納されている。そして、この潮解性吸湿剤2を収納した包装体5を可透湿部3の空間部3a内に確実に配置・収容するため、前記可透湿部3の可透湿部開口3bを塞ぐように円板状の仕切部材6がこの可透湿部3と容器本体4との間に配設されるようになっている。この仕切部材6は、前記容器本体4の上端凸部4dと略同径であり、潮解液8が通過する透孔6aが複数設けられている。
【0019】
また、前記潮解性吸湿剤2を収容する可透湿部3と潮解液8を貯溜する容器本体4とは、この可透湿部3と容器本体4との間に前記仕切部材6を配置した状態で固定手段である透口7aを形成した略管状の固定部材7によって一体的に密着固定されるようになっている。前記固定部材7の内周面には前記容器本体4の雄ねじ4cに噛合する雌ねじ7cが形成されており、この雌ねじ7cを前記雄ねじ4cに噛合することによって固定部材7の天面7bが仕切部材6を押圧して、縁部3cの下端面と,仕切部材6の上端面及びこの仕切部材6の下端面と上端凸部4dの上端面とを一体的に密着固定させて除湿容器1が構成されるようになっている。
【0020】
ここで、可透湿部3について説明する。
前記可透湿部3には、十分な透湿性と、十分な非透水性と、立体的に形成することのできる成形性(以下賦型性と記載する)とを備えるように、例えば超高分子量ポリエチレン材料で形成した、微細な透孔を複数有する多孔質構造体を成形したものである。
【0021】
前記多孔質構造体は、除湿器1の十分な透湿性としての基本性能を考慮すると、透湿度1,000g/m2・day以上であることが望まれる。この多孔質構造体の透湿度は、この多孔質構造体が有する微細孔の孔径を大きく形成したり、気孔率を高めることによって向上させることが可能であるが、透湿度を過度に高めることは非透水性の減少の要因になってしまうので、本実施形態ではこの可透湿部3の透湿度の上限値を6,000g/m2・dayに設定している。
【0022】
また、前記多孔質構造体は、除湿器1の十分な非透水性としての基本性能を考慮すると、可透湿部3及び除湿器1全体の形状にもよるが、耐水圧10cm以上であることが望まれる。しかし、非透水性の容器本体4の本体開口部4bの上部に可透湿部3を配置する構成の除湿器1では潮解性吸湿剤2がほぼ無くなったとき、潮解液8が貯溜部4aに数百ml貯溜されることになる。このため、この状態で、万一、除湿器1が転倒してしまっても潮解液8が除湿器1の外部に絶対に漏出することがないように、前記可透湿部3の非透水性が十分に保持するために本実施形態では耐水圧を20cm以上に設定している。
【0023】
さらに、前記多孔質構造体の賦型性としては、立体的に形成することが可能であれば特に制限はないが、この可透湿部3を形成する多孔質構造体の厚み寸法に関しては0.5mmから6.0mmの範囲内であることが望ましく、特に、厚み寸法が0.2mm以下である場合には成形が困難になって構造部材としての機械的強度を確保することができなくなってしまい、厚み寸法を0.5mm以上に設定することによって、機械的強度が大幅に増大して破損し難くくなることにより取扱い性が向上する。一方、厚み寸法が5.0mm以上であると賦型が困難になってしまう。
【0024】
なお、前記多孔質構造体に撥水処理を施して非透水性を向上させる場合においては、さらに、透湿性を高めることも可能であり、撥水処理を施すことによって製品には何ら不都合が生じることはなく、むしろ多孔質構造体に撥水処理を施すことが望ましい。
【0025】
また、可透湿部3の立体形状に関しては特にドーム型形状に限定されるものではないが、除湿器外部の外気を除湿器内部に多く取り込んで、潮解性吸湿剤2と外気との接触する割合を増大させるため、可透湿部3の表面積が大きくなるように、前記容器本体4の本体開口部4bの開口面積に対して110パーセントから250パーセントの範囲になるように設計することが好ましく、本実施形態では賦型性が良いことから上述のように可透湿部3をドーム型形状などに形成して外気と潮解性吸湿剤2との接触する割合を増大させるようにしている。
【0026】
ここで、前記超高分子量ポリエチレン材料による多孔質構造体の製造方法の1例を説明する。
まず、多孔質構造体を得るため、超高分子量ポリエチレン粉末を金型に充填した後、金型内をこの超高分子量ポリエチレンの融点以上の温度に加熱して、金型内の超高分子量ポリエチレンを焼結してブロック状の成形体を得る。
【0027】
次に、金型を冷却した後、金型からブロック状に成形された多孔質構造体を取り出し、この多孔質構造体を旋盤などで所定の厚さに切削して多孔質構造体円板シートを得る。
【0028】
そして、上述のように得られた多孔質構造体円板シートを賦型処理してドーム型形状に形成する。このとき、前記多孔質構造体円板シートを120℃から180℃の間に加熱してリング状金型に挟んだ後、凸型金型を圧入して立体形状に形成する。このときの可透湿部3の立体形状は、上述したように賦型が比較的容易で、外表面積が大きくなるドーム型形状としている。
【0029】
なお、上述の製造方法で、多孔質構造体を得る際、金型に充填された超高分子量ポリエチレン粉末を加熱した水蒸気雰囲気中で焼結するので、この金型には少なくとも加熱水蒸気導入用の開口部を設けている。
【0030】
また、焼結時、超高分子量ポリエチレン粉末が融点以上の温度に加熱されて溶融状態になるが、超高分子量ポリエチレンは溶融粘度が高いので、流動することなく、粉末状態での形状をほとんど維持して、隣接する粉末相互の接触部位が熱融着する一方、粉末相互の非接触部が多孔質構造体の微孔になって、複数の微孔を有する多孔質構造体のブロックが成形される。このときの焼結に要する時間は超高分子量ポリエチレン粉末の充填量及び水蒸気の温度などによって変化するが、通常約1から12時間を要する。
【0031】
さらに、水蒸気を超高分子量ポリエチレンの融点以上に昇温させるため、加圧状態にしているので、水蒸気は金型に充填された超高分子量ポリエチレン粉末間に容易に侵入していく。したがって、金型に充填された超高分子量ポリエチレン粉末の焼結は、耐圧容器に水蒸気導入管を設け、この水蒸気導入管に設けた開閉バルブを開状態にして加熱水蒸気を導入する方法によって行われる。
【0032】
又、金型内に充填されている超高分子量ポリエチレン粉末の隣接する粉末相互の間に加熱水蒸気をさらに容易に侵入させるため、前記ポリエチレン粉末を金型に充填した後、金型を耐圧容器に入れ、約1mmHgから100mmHgの範囲の減圧状態にして脱気操作を施した後、加熱された水蒸気雰囲気中で焼結するとよい。
【0033】
さらにまた、焼結後のブロック状に成形された多孔質構造体を冷却する際、多孔質構造体に亀裂が発生するのを防止するため急冷を避ける。このため、室温に放置する冷却方法などを採用する。このとき、ブロック状に成形された多孔質構造体が金型に入ったままの状態であっても、金型から取り出した状態であってもよい。
【0034】
次に、本実施形態の除湿器1の可透湿部3の具体的な製造方法の1例を説明する。
まず、可透湿部3を形成するための多孔質構造体を形成するために、内径寸法を容器本体4の外径寸法に設定した円筒形空間部を有する金型に超高分子量ポリエチレン粉末を充填する。そして、この金型を金属製耐圧容器に入れ、真空ポンプを作動させて雰囲気圧を30mmHgまで減圧し、充填された粉末間の空気を脱気する。脱気後、前記真空ポンプを停止させて水蒸気導入バルブを開いて、金型内に例えば温度158℃で6気圧の水蒸気を導入する。この状態で60分間加熱する。このことによって、金型内の超高分子量ポリエチレン粉末が焼結して丸棒状の多孔質構造体となる。
【0035】
次に、この丸棒状の多孔質構造体が形成されている金型を室温25℃の中に3時間放置して冷却する。そして、冷却された金型から直径寸法が容器本体4の外径寸法に設定された丸棒状の多孔質構造体を取り出す。
【0036】
次いで、前記多孔質構造体を旋盤によって例えば厚み寸法が1mmとなるように切削して、直径寸法が容器本体4の外径寸法と略同径で、厚み寸法が1mm、気孔率25%、平均孔径30μm、ガーレー値4秒/100mm2の白色不透明の多孔質構造体円板シートを得る。
【0037】
上述のように得られた超高分子量ポリエチレンの多孔質構造体円板シートにフッ素系撥水剤を、例えば固形分濃度3%の液に、速度1m/分で浸漬含浸させた後、130℃で乾燥させて、固化定着させる。このことによって、前記多孔質構造体円板シートの耐水圧が20cm、透湿度が4000g/m2・dayになった。
【0038】
そして、この超高分子量ポリエチレンの多孔質構造体円板シートを所定寸法に切断した後、この多孔質構造体円板シートを140℃で1分間加熱し、直径寸法を2rよりやや大きく設定した透孔を有するリング状金型に挟持した後、凸型部を圧入して賦型して冷却することによって、凸型の立体形状に形成された可透湿部3が成形される。
【0039】
ここで、本実施形態の除湿器1の作用を説明する。
まず、容器本体4,仕切部材6,可透湿部3,固定部材7及び潮解性吸湿剤2を収納した包装体5を用意する。
【0040】
次に、容器本体4の本体開口部4aの上端面に仕切部材6を配置し、この仕切部材6の上端面に潮解性吸湿剤2を収納した包装体5を載置する。
【0041】
次いで、この包装体5が載置されている仕切部材6の上部面にドーム型形状の可透湿部3を配置する。そして、固定部材7の透口7aを凸型のドーム部に挿通させて、固定部材7を可透湿部3の縁部3cの上面側に配置して、固定部材7に形成されている雌ねじ部7cを容器本体4の雄ねじ部4cに螺合して可透湿部3と、仕切部材6と、容器本体4とを密着させて一体的に固定する。
【0042】
上述のように形成された除湿器1を洋服ダンスなどの所望の位置に配置する。しばらくすると、ドーム型形状の可透湿部3に設けられている複数の微孔を通って外気が可透湿部内に侵入する。可透湿部内に侵入した外気は、包装体5を通過して潮解性吸湿剤2に接触する。
【0043】
すると、潮解性吸湿剤2に外気が接触することによって、潮解液8が生じる。この潮解液8は、仕切部材6に設けられている透孔6aを通って容器本体4の貯溜部4aに貯溜されていく。このとき、可透湿部3をドーム型形状に形成したことにより、可透湿部内に進入する外気の量が増えることによって、外気と潮解性吸湿剤2との接触する割合が増大して、4日間で約70グラムの潮解液が得られ、8日間では約100グラムの潮解液を得られる。
【0044】
このように、潮解性吸湿剤を収容する収容部となる可透湿部を、透湿性及び非透水性を有し、且つ成形性を備えた多孔質構造体からなるシートで立体形状に形成することにより、潮解性吸湿剤へ外気を導くことのできる可透湿部の外表面積を大きくして、且つ潮解液が漏出することのない除湿器を構成することができる。
【0045】
また、前記可透湿部を形成する多孔質構造体からなるシートは機械的強度を有すると共に、成形性を備えた厚みに設定しているので、生産性が大幅に向上すると共に、取扱いが容易になって、生産コスト及び加工コストの低減を図ることができる。
【0046】
さらに、容器本体,仕切部材,可透湿部,固定部材及び潮解性吸湿剤を収納した包装体で構成される除湿器を組み立てる際、可透湿部と容器本体とを固定部材によって密着されて一体的に組み立てる構造にしているので、組立て性が大幅に向上して組立てコストの低減を図ることができる。
【0047】
又、本発明における前記多孔質構造体シートを、透湿性、非透水性、賦型性及び商品の安定性、生産性及び吸湿能力を考慮して、厚み寸法を0.8mmから1.5mmの範囲に設定することによって、成形性を損なうことなく、機械的強度を大幅に増大させることができる。このことにより、可透湿部の繰り返しの使用が可能になり、可透湿部内に収容されていた潮解性吸湿剤が無くなって、貯溜部に潮解液が貯溜されているとき、上記組立て時の手順と逆の手順で除湿器を分解して貯溜部に貯溜された潮解液を廃棄して、新たな潮解性吸湿剤を収容した包装体に交換して再び組み立てることによって、除湿器1の繰り返し使用が可能になり、省資源化に貢献した除湿器が提供される。
【0048】
なお、潮解性吸湿剤2と外気との接触する割合を増大させるために、この容器本体4を多孔質構造体で形成するようにしてもよい。このとき、容器本体4の耐水圧を10cm以上に設定しておく。また、この容器本体4内に貯溜されていく潮解液8の貯溜量を目視によって容易に確認することができるように容器本体4を透明もしくは半透明な部材で形成するとよい。透明な部材としてはポリカーボネートやポリエチレンテレフタレートなどを用い、半透明な部材としてはポリプロピレンなどを用いる。
【0049】
なお、本実施形態においては可透湿部の立体形状を半球形状などのドーム型形状としているが、可透湿部の立体形状はドーム型形状に限定されるものではない。
【0050】
また、前記固定部材の外周面に凹凸部を形成することによって、この凹凸部が滑り止めになって、この固定部材を容器本体に螺合する際の作業性が大幅に向上する。
【0051】
さらに、前記容器本体の上端凸部の上面と前記仕切部材との間などにOリング形状のパッキン部材を配設することによって、容器本体と仕切部材との密着性を高める構成にしてもよい。
【0052】

BACKGROUND OF THE INVENTION
The present invention relates to a dehumidifier that performs dehumidification using a deliquescent hygroscopic agent.
[0002]
[Prior art]
Conventionally, a dehumidifier using a deliquescent hygroscopic agent has been widely used for the purpose of dehumidification in a closet or a chiffon. As such a dehumidifier, for example, the container body is divided into two space portions, an upper space portion and a lower space portion, by a saucer having a plurality of dropping holes for deliquescent liquid. There is a structure in which a deliquescent hygroscopic agent such as calcium chloride or magnesium chloride in the form of particles or particles is packed, and the deliquescent liquid dehydrated by contact with moisture in the outside air is stored in the lower space, and the container While the opening of the main body is covered with a film-like moisture-permeable and non-permeable moisture-permeable / non-permeable film, and the film-like moisture-permeable / non-permeable film is covered with a lid for protection The lid is provided with a ventilation portion so that the outside air containing moisture is guided to the deliquescent hygroscopic agent.
[0003]
In this dehumidifier, the moisture in the outside air passes through the ventilation part provided in the lid, then passes through the moisture-permeable / non-permeable film, and comes into contact with the deliquescent hygroscopic agent packed in the upper space part of the container body. . Then, when the moisture in the outside air comes into contact with the deliquescent hygroscopic agent, the deliquescent liquid is eventually produced, and this deliquescent liquid is dripped into the lower space portion of the container body through the dripping hole formed in the tray and stored. It will be done. The moisture absorption rate of the deliquescent hygroscopic agent at this time is determined by the ratio of the outside air that comes into contact with the deliquescent hygroscopic agent packed in the upper space portion, so that the ratio of the outside air taken into the upper space portion in this dehumidifier Depending on the coating area of the opening of the main body, the larger the coating area, the greater the proportion of contact between the outside air and the deliquescent hygroscopic agent and the better the moisture absorption rate. In the dehumidifier configured as described above, about 25 grams of deliquesce solution was obtained in 4 days, and about 50 grams of deliquesce solution was obtained in 8 days.
[0004]
However, in order to improve the moisture absorption rate, if the coating area of the opening of the container body is increased as described above, the container body has a large bottom area. A large space is required. In addition, the thickness dimension of the sheet-like moisture-permeable / non-water-permeable coating covering the opening of the container main body is formed as thin as several tens of μm to several hundreds of μm. There is a risk of breaking the moisture-permeable and water-impermeable film during transportation, etc.If the moisture-permeable and water-impermeable film covering the opening is broken, the deliquescent hygroscopic agent packed in the upper space is removed from the container body. It could be spilled to the outside or the deliquescent solution stored in the lower space could leak and contaminate clothing, bedding, furniture, etc., so handling was difficult and sufficient care had to be taken.
[0005]
Further, as described above, since the moisture absorption rate depends on the ratio of the outside air that contacts the deliquescent hygroscopic agent, a dehumidifier that increases the ratio of the outside air that leads to the deliquescent hygroscopic agent is disclosed in JP-A-57-1072. And Japanese Utility Model Publication No. 4-8985. According to these dehumidifiers, in order to increase the ratio of contact between the deliquescent hygroscopic agent such as sodium chloride and the outside air, the deliquescent hygroscopic agent is larger than the film area of the opening of the container body provided with a large number of through holes. It arrange | positions inside the dome-shaped member formed in the substantially hemispherical shape so that it may become. In this dehumidifier, outside air enters the inside of the dome-shaped member from the vent of the dome-shaped member having a large surface area, and contacts with the deliquescent moisture absorbent to generate deliquescent liquid, which is stored in the container body. It has come to be.
[0006]
Furthermore, in Japanese Utility Model Publication No. 61-10743, the deliquescent hygroscopic agent is covered with a flexible semi-permeable membrane having high followability and formed into a hemispherical shape, thereby increasing the ratio of contact with the outside air, A dehumidifier is shown in which the deliquescent liquid stored in the container is prevented from flowing out of the container when the dehumidifier is overturned. In this dehumidifier, the outside air containing moisture passes through the semipermeable membrane and comes into contact with the hygroscopic agent to generate deliquescent liquid. The deliquescent liquid flows down and is stored in the container. At this time, the deliquescent hygroscopic agent is deliquescent by contact with the moisture in the outside air and deliquescent, and gradually deforms from the initial hemispherical shape, but a semipermeable membrane is possible. Since it has flexibility, the semipermeable membrane and the hygroscopic agent are always kept in close contact with each other, and the hygroscopic efficiency of the deliquescent hygroscopic agent in the semipermeable membrane is maintained.
[0007]
[Problems to be solved by the invention]
However, in the dehumidifier disclosed in the above Japanese Patent Application Laid-Open No. 57-1072 or Japanese Utility Model Publication No. 4-8985, the dehumidifier is turned over while the deliquescent liquid is stored in the container body. If this happens, there is a problem that the deliquescent liquid stored in the dome-shaped or hemispherical member that contains the deliquescent hygroscopic agent disposed at the top of the container body will flow out. there were.
[0008]
Further, the dehumidifier disclosed in the Japanese Utility Model Publication No. 61-10743 has a porous bottom plate provided with a plurality of through holes on a flange of a cylindrical container to cover the opening of the container, and the porous bottom plate A hygroscopic agent is heaped up in a hemispherical shape, and the outer surface of the hygroscopic agent is adhered to and covered with the semipermeable membrane, and the periphery of the semipermeable membrane is adhered to the periphery of the porous bottom plate. The outer periphery of the membrane is covered with a hemispherical mesh lid, and the peripheral edge of this mesh lid is provided with a locking portion that can be detachably attached to the flange of the container with the periphery of the porous bottom plate as a packing. There is a problem that the assembly becomes complicated due to the increase in the number.
[0009]
Further, since the moisture-permeable / water-impermeable film is formed of a semi-permeable film, there is a risk of damage during assembly.
[0010]
The present invention has been made in view of the above circumstances, the ratio of contact between the outside air and the deliquescent hygroscopic agent is large, and the deliquescent liquid stored in the container body does not flow out when the dehumidifier falls, The object is to provide a dehumidifier with a simple structure.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1 and 2 relate to an embodiment of the present invention, FIG. 1 is a diagram illustrating a schematic configuration of a dehumidifier, and FIG. 2 is an exploded explanatory diagram illustrating an assembly configuration of the dehumidifier.
[0015]
As shown in the figure, the dehumidifier 1 is a substantially hemispherical three-dimensional solid body having a deliquescent hygroscopic agent 2 that absorbs moisture by contacting with moisture in the outside air, and a space portion 3a that accommodates the deliquescent hygroscopic agent 2. A space for storing a permeable portion 3 formed of a member having moisture permeability and non-water permeability, which will be described later, and a deliquescent solution 8 deliquescent when the deliquescent absorbent 2 is in contact with moisture in the outside air. It is mainly comprised by the substantially cylindrical container main body 4 which has the storage part 4a which is a part.
[0016]
The container body 4 is not particularly limited as long as it is a structure that does not leak deliquescent fluid, and a circular body opening 4b having a radius r is formed at the upper end of the container body 4, An upper end convex portion 4d that protrudes from the outer peripheral surface of the container body 4 having the male screw 4c formed on the outer peripheral surface is formed.
[0017]
The moisture permeable portion 3 has, for example, a substantially hemispherical shape, and is substantially outside the outer surface of the hemisphere with respect to the opening area of the permeable moisture portion opening 3b facing the circular body opening 4b having a radius r of the container body 4. The surface area ratio is set to 180% or the like to form a three-dimensional convex shape. At this time, if the ratio of the outer surface area is set to 200% with respect to the opening area of the moisture permeable portion opening 3b and the moisture permeable portion 3 is formed in a hemispherical three-dimensional shape, the opening of the moisture permeable portion opening 3b is formed. Since the shape is a circle, the area of this circle can be represented by πr 2 , and the surface area of the sphere can be represented by 4πr 2 , so when the outer surface area is set to 200% of the moisture permeable portion opening 3b, The value of the surface area is 2πr 2, and this outer surface area corresponds to half of the surface area of the sphere, so that the shape of the moisture permeable portion 3 becomes a hemispherical dome shape. In addition, an edge portion 3c formed on the upper end convex portion 4d of the container body 4 to have substantially the same diameter is formed on the outer periphery of the permeable moisture portion opening 3b of the permeable moisture portion 3 .
[0018]
The deliquescent hygroscopic agent 2 accommodated in the space portion 3a of the moisture permeable portion 3 is made of a non-woven fabric having high air permeability and water permeability so as to be easily accommodated in the space portion 3a. It is stored in the formed package 5. And in order to arrange | position and accommodate the packaging body 5 which accommodated this deliquescent hygroscopic agent 2 in the space part 3a of the permeable moisture part 3, so that the permeable moisture part opening 3b of the said permeable moisture part 3 may be plugged up. A disc-shaped partition member 6 is arranged between the moisture permeable portion 3 and the container body 4. The partition member 6 has substantially the same diameter as the upper end convex portion 4d of the container body 4 and is provided with a plurality of through holes 6a through which the deliquescent liquid 8 passes.
[0019]
In addition, the permeable portion 3 for storing the deliquescent hygroscopic agent 2 and the container body 4 for storing the deliquescent liquid 8 have the partition member 6 disposed between the permeable moisture portion 3 and the container body 4. In this state, the fixing member 7 is formed to have a through hole 7a, which is a fixing means, so that the fixing member 7 is integrally fixed. A female screw 7c that meshes with the male screw 4c of the container body 4 is formed on the inner peripheral surface of the fixing member 7, and by engaging the female screw 7c with the male screw 4c, the top surface 7b of the fixing member 7 becomes a partition member. The dehumidifying container 1 is constructed by pressing the lower edge 6 of the edge 3c, the upper end surface of the partition member 6 and the lower end surface of the partition member 6 and the upper end surface of the upper end convex portion 4d in close contact with each other. It has come to be.
[0020]
Here, the moisture permeable part 3 is demonstrated.
The moisture permeable portion 3 is provided with, for example, ultra-high moisture so as to have sufficient moisture permeability, sufficient non-water permeability, and formability that can be three-dimensionally formed (hereinafter referred to as moldability). A porous structure having a plurality of fine pores formed from a molecular weight polyethylene material is molded.
[0021]
In consideration of the basic performance of the dehumidifier 1 as sufficient moisture permeability, the porous structure is desired to have a moisture permeability of 1,000 g / m 2 · day or more. The water vapor transmission rate of this porous structure can be improved by forming the pore diameter of the fine pores of this porous structure large or by increasing the porosity. In this embodiment, the upper limit value of the moisture permeability of the moisture permeable portion 3 is set to 6,000 g / m 2 · day because it causes a decrease in non-water permeability.
[0022]
In addition, considering the basic performance of the dehumidifier 1 as sufficiently impermeable, the porous structure has a water pressure resistance of 10 cm or more, depending on the shape of the moisture permeable portion 3 and the entire dehumidifier 1. Is desired. However, in the dehumidifier 1 having the structure in which the moisture permeable portion 3 is disposed above the main body opening 4b of the non-permeable container body 4, when the deliquescent hygroscopic agent 2 is almost lost, the deliquescent liquid 8 is stored in the reservoir 4a. Several hundred ml will be stored. For this reason, in this state, even if the dehumidifier 1 falls down, the non-water-permeable portion 3 of the moisture permeable portion 3 prevents the deliquescent liquid 8 from leaking out of the dehumidifier 1 by any chance. However, in this embodiment, the water pressure resistance is set to 20 cm or more.
[0023]
Further, the formability of the porous structure is not particularly limited as long as it can be three-dimensionally formed, but the thickness dimension of the porous structure forming the moisture permeable portion 3 is 0. Desirably, the thickness is within the range of 0.5 mm to 6.0 mm. Particularly, when the thickness dimension is 0.2 mm or less, molding becomes difficult, and the mechanical strength as a structural member cannot be secured. Therefore, by setting the thickness dimension to 0.5 mm or more, the mechanical strength is greatly increased, and it becomes difficult to break, thereby improving the handleability. On the other hand, if the thickness dimension is 5.0 mm or more, shaping becomes difficult.
[0024]
In addition, in the case where the porous structure is subjected to water repellent treatment to improve water impermeability, it is also possible to improve moisture permeability, and the product is inconvenienced by performing the water repellent treatment. Rather, it is desirable to subject the porous structure to a water repellent treatment.
[0025]
Further, the three-dimensional shape of the moisture permeable portion 3 is not particularly limited to the dome shape, but a large amount of outside air outside the dehumidifier is taken into the dehumidifier, and the deliquescent hygroscopic agent 2 contacts the outside air. In order to increase the ratio, it is preferable that the surface area of the moisture permeable portion 3 is increased so that the surface area of the main body opening 4b of the container body 4 is 110% to 250%. In this embodiment, since the moldability is good, the permeable moisture portion 3 is formed in a dome shape or the like as described above to increase the ratio of contact between the outside air and the deliquescent hygroscopic agent 2.
[0026]
Here, an example of the manufacturing method of the porous structure by the said ultra high molecular weight polyethylene material is demonstrated.
First, in order to obtain a porous structure, after the ultra high molecular weight polyethylene powder is filled in the mold, the inside of the mold is heated to a temperature equal to or higher than the melting point of the ultra high molecular weight polyethylene, and the ultra high molecular weight polyethylene in the mold is obtained. Is sintered to obtain a block-shaped molded body.
[0027]
Next, after cooling the mold, the porous structure formed into a block shape is taken out from the mold, and this porous structure is cut to a predetermined thickness with a lathe or the like to obtain a porous structure disk sheet. Get.
[0028]
Then, the porous structure disk sheet obtained as described above is subjected to a shaping process to form a dome shape. At this time, the porous structure disc sheet is heated between 120 ° C. and 180 ° C. and sandwiched between ring-shaped molds, and then a convex mold is pressed into a three-dimensional shape. The three-dimensional shape of the moisture permeable portion 3 at this time is a dome shape that is relatively easy to mold and has a large outer surface area as described above.
[0029]
When the porous structure is obtained by the above-described manufacturing method, the ultrahigh molecular weight polyethylene powder filled in the mold is sintered in a heated water vapor atmosphere. An opening is provided.
[0030]
Also, during sintering, ultra high molecular weight polyethylene powder is heated to a temperature above its melting point and becomes molten, but ultra high molecular weight polyethylene has a high melt viscosity, so it retains its shape in a powder state without flowing. Then, the contact portions between the adjacent powders are heat-sealed, while the non-contact portions between the powders become micropores of the porous structure, and a block of the porous structure having a plurality of micropores is formed. The The time required for sintering at this time varies depending on the filling amount of the ultra-high molecular weight polyethylene powder, the temperature of the water vapor, and the like, but usually requires about 1 to 12 hours.
[0031]
Furthermore, since the steam is heated to a temperature higher than the melting point of the ultrahigh molecular weight polyethylene, the water vapor is easily invaded between the ultrahigh molecular weight polyethylene powders filled in the mold. Accordingly, the ultrahigh molecular weight polyethylene powder filled in the mold is sintered by a method in which a steam inlet pipe is provided in the pressure vessel, and the opening / closing valve provided in the steam inlet pipe is opened to introduce heated steam. .
[0032]
In addition, in order to allow heated steam to more easily enter between adjacent powders of ultra-high molecular weight polyethylene powder filled in the mold, after filling the polyethylene powder into the mold, the mold is put into a pressure vessel. It is preferable to sinter in a heated steam atmosphere after performing deaeration operation under reduced pressure in the range of about 1 mmHg to 100 mmHg.
[0033]
Furthermore, when the porous structure formed into a block shape after sintering is cooled, rapid cooling is avoided in order to prevent the porous structure from cracking. For this reason, the cooling method etc. which are left to stand at room temperature are employ | adopted. At this time, the porous structure formed into a block shape may be in a state where it is still in the mold or may be in a state where it is taken out from the mold.
[0034]
Next, an example of a specific method for manufacturing the moisture permeable portion 3 of the dehumidifier 1 of the present embodiment will be described.
First, in order to form a porous structure for forming the moisture permeable portion 3, an ultrahigh molecular weight polyethylene powder is applied to a mold having a cylindrical space portion whose inner diameter is set to the outer diameter of the container body 4. Fill. Then, this mold is put in a metal pressure vessel, the vacuum pump is operated, the atmospheric pressure is reduced to 30 mmHg, and the air between the filled powder is deaerated. After deaeration, the vacuum pump is stopped and the water vapor introduction valve is opened to introduce water vapor of 6 atm at a temperature of 158 ° C., for example. Heat in this state for 60 minutes. As a result, the ultrahigh molecular weight polyethylene powder in the mold is sintered to form a round bar-like porous structure.
[0035]
Next, the mold in which the round bar-like porous structure is formed is allowed to cool at room temperature of 25 ° C. for 3 hours. Then, a round bar-like porous structure having a diameter dimension set to the outer diameter dimension of the container body 4 is taken out from the cooled mold.
[0036]
Next, the porous structure is cut with a lathe so that the thickness dimension is, for example, 1 mm, the diameter dimension is substantially the same as the outer diameter dimension of the container body 4, the thickness dimension is 1 mm, the porosity is 25%, and the average A white opaque porous structure disc sheet having a pore size of 30 μm and a Gurley value of 4 seconds / 100 mm 2 is obtained.
[0037]
The ultrahigh molecular weight polyethylene porous structure disc sheet obtained as described above was impregnated with a fluorine-based water repellent, for example, in a liquid having a solid content concentration of 3% at a rate of 1 m / min, and then 130 ° C. Dry with to solidify and fix. As a result, the water pressure resistance of the porous structure disc sheet was 20 cm, and the water vapor transmission rate was 4000 g / m 2 · day.
[0038]
Then, after the ultrahigh molecular weight polyethylene porous structure disk sheet was cut to a predetermined size, the porous structure disk sheet was heated at 140 ° C. for 1 minute, and the diameter dimension was set slightly larger than 2r. After being sandwiched between ring-shaped molds having holes, the convex portion is press-fitted, molded, and cooled to mold the moisture permeable portion 3 formed into a convex three-dimensional shape.
[0039]
Here, the effect | action of the dehumidifier 1 of this embodiment is demonstrated.
First, a package 5 containing a container body 4, a partition member 6, a moisture permeable portion 3, a fixing member 7 and a deliquescent hygroscopic agent 2 is prepared.
[0040]
Next, the partition member 6 is disposed on the upper end surface of the main body opening 4 a of the container body 4, and the package 5 containing the deliquescent moisture absorbent 2 is placed on the upper end surface of the partition member 6.
[0041]
Next, a dome-shaped moisture permeable portion 3 is disposed on the upper surface of the partition member 6 on which the package 5 is placed. Then, the through hole 7a of the fixing member 7 is inserted into the convex dome portion, the fixing member 7 is arranged on the upper surface side of the edge portion 3c of the moisture permeable portion 3, and the female screw formed in the fixing member 7 The part 7c is screwed into the male threaded part 4c of the container body 4, and the moisture permeable part 3, the partition member 6, and the container body 4 are brought into intimate contact and fixed integrally.
[0042]
The dehumidifier 1 formed as described above is arranged at a desired position such as clothes dance. After a while, outside air enters the permeable portion through a plurality of micro holes provided in the dome-shaped permeable portion 3. The outside air that has entered the moisture permeable portion passes through the package 5 and contacts the deliquescent hygroscopic agent 2.
[0043]
Then, the deliquescent liquid 8 is produced by the outside air coming into contact with the deliquescent hygroscopic agent 2. The deliquescent solution 8 is stored in the storage portion 4 a of the container body 4 through the through hole 6 a provided in the partition member 6. At this time, by forming the permeable portion 3 in a dome shape, the amount of outside air entering the permeable portion increases, so that the ratio of contact between the outside air and the deliquescent hygroscopic agent 2 increases, About 70 grams of deliquescent is obtained in 4 days, and about 100 grams of deliquesce is obtained in 8 days.
[0044]
As described above, the moisture permeable portion serving as the accommodating portion for containing the deliquescent hygroscopic agent is formed into a three-dimensional shape with a sheet made of a porous structure having moisture permeability and non-water permeability and having moldability. Accordingly, it is possible to configure a dehumidifier that increases the outer surface area of the moisture permeable portion that can guide the outside air to the deliquescent hygroscopic agent and does not leak the deliquescent liquid.
[0045]
In addition, the sheet made of the porous structure forming the moisture permeable portion has mechanical strength and is set to a thickness having formability, so that productivity is greatly improved and handling is easy. Thus, the production cost and the processing cost can be reduced.
[0046]
Furthermore, when assembling a dehumidifier composed of a container body, a partition member, a moisture permeable portion, a fixing member, and a packaging body containing a deliquescent hygroscopic agent, the moisture permeable portion and the container body are closely attached by the fixing member. Since the structure is integrally assembled, the assemblability is greatly improved and the assembling cost can be reduced.
[0047]
In addition, the porous structure sheet according to the present invention has a thickness dimension of 0.8 mm to 1.5 mm in consideration of moisture permeability, non-water permeability, moldability, product stability, productivity, and moisture absorption capacity. By setting the range, the mechanical strength can be greatly increased without impairing the moldability. This makes it possible to repeatedly use the moisture permeable part, and when the deliquescent absorbent stored in the moisture permeable part is lost and the deliquescent liquid is stored in the storage part, The dehumidifier 1 is repeated by disassembling the dehumidifier in the reverse order of the procedure and discarding the deliquescent solution stored in the reservoir, replacing it with a package containing a new deliquescent hygroscopic agent, and reassembling it. A dehumidifier that can be used and contributed to resource saving is provided.
[0048]
In order to increase the ratio of contact between the deliquescent hygroscopic agent 2 and the outside air, the container body 4 may be formed of a porous structure. At this time, the water pressure resistance of the container body 4 is set to 10 cm or more. Further, the container body 4 may be formed of a transparent or translucent member so that the stored amount of the deliquescent solution 8 stored in the container body 4 can be easily confirmed visually. As the transparent member, polycarbonate or polyethylene terephthalate is used, and as the translucent member, polypropylene or the like is used.
[0049]
In the present embodiment, the three-dimensional shape of the moisture permeable portion is a dome shape such as a hemispherical shape, but the three-dimensional shape of the moisture permeable portion is not limited to the dome shape.
[0050]
Further, by forming the concavo-convex portion on the outer peripheral surface of the fixing member, the concavo-convex portion is prevented from slipping, and the workability when the fixing member is screwed to the container body is greatly improved.
[0051]
Furthermore, you may make it the structure which improves the adhesiveness of a container main body and a partition member by arrange | positioning an O-ring-shaped packing member between the upper surface of the upper end convex part of the said container main body, and the said partition member.
