Description

【0001】
【発明の属する技術分野】
本発明は、各種の液体に用いることができ、特に飲料液用に好適な殺菌液生成装置及び殺菌液生成装置付き小型簡易浄水器に関するものである。
【0002】
【従来の技術】
従来から食品用等の液体における殺菌技術は重要な役割を担っており、各種の殺菌方法が実施されている。
代表的なものとして化学薬品を使用する方法や、加熱する方法、加圧する方法、紫外線・放射線・超音波の照射による方法があるが、化学薬品を使用する方法では添加薬剤の残留が問題となる場合があり、加熱・加圧する方法はクリーンではあるが、適用される対象物が限定されると共に大がかりな設備が必要で消費エネルギー大きいという不都合がある。
なお、活性炭や中空糸フィルター等を用いて雑菌を吸着する濾過式の浄水器も知られているが、構造が簡単となる利点はあるものの殺菌作用自体は無く、濾過材である活性炭や中空糸フィルター等の表面に付着した菌体が増殖して目詰まりを起こしやすい等の不都合も生じている。
一方、近年の研究により細胞−電極間の電子移動反応を利用した電気化学的殺菌法が開発され、その内の低電圧殺菌法を用いた浄水器が公知となっている。即ち図9に示すように、浄水器51下方には陽電極(活性炭素繊維)52及び陰電極53が設置されて注入された原水(上水)内に浸積しており、乾電池54により1.5ボルトの電位を与えると、その間の原水に存在する菌体は死滅し、さらに活性炭素繊維に通水することにより浄水が生成される。この方法によれば安全かつ比較的簡単な構造で殺菌繁殖を抑制できるが、更なる簡単な構成の殺菌装置が望まれていた。
なお、貯液容器内に濾過材を浸漬させた各種の小型簡易浄水器も存在しているが、これらは濾過材への雑菌の吸着作用に留まっており、更なる水質向上は使用者にとって有益であると考えられる。
【0003】
【発明が解決しようとする課題】
本発明は、上記実状に鑑み、簡単な構成でありながら安全で、且つ、効果的な液体の殺菌を実現できる殺菌液生成装置及び殺菌液生成装置付き小型簡易浄水器を提供することを目的とする。
【0004】
【課題を解決するための手段】
上記課題を解決するために鋭意検討の結果、本発明においては、液体を介在させることにより起電力を0.7ボルト以上発生させることのできる、異種金属接触腐食における卑な金属からなる両端を解放させた筒状の陰電極とその内側に非接触状態に配置したオープンセル構造の異種金属接触腐食における貴な金属からなる陽電極とで構成する殺菌液生成装置であれば、両極間に介在する液体中の多数の菌体をオープンセル構造の陽電極に広い面積で接触させて死滅させることができるので殺菌に好適であることを究明した。
その場合、陰電極をマグネシウムとするのが好ましく、マグネシウム細線からなるオープンセル筒状構造にするのが最適である。
また、陽電極が銅または銅合金であると液体中に溶け出しにくいと共に汎用材料であるため廉価となるので好ましい。
なお、陰電極の下部に濾過装置を設けると液体中の異物を吸着することができるのでより好ましいものとなる。
さらに、本殺菌装置は小型に形成できるので各種の液体循環装置内に通液可能に装着することができる。
したがって、貯液容器内に濾過部を収容した液体強制循環流路に搭載することも可能であり、水質の向上した小型簡易浄水器に仕上げることもできる。
【0005】
【発明実施の形態】
本発明における殺菌作用を発生させる原理は、上述した電気化学的殺菌法に示されるように、液体中に存在する菌体がマイナス(−)に帯電しているので、陽電極に接触する状態に引き寄せられると共にこの状態で0.7ボルト以上の電圧が印可されると生菌率が急激に減少する(菌体が死滅する)理論に基づくものであるが、該殺菌法における印可電圧の発生方法が乾電池等の電源を使用することに換え、液体中に浸積するように異種金属接触腐食における卑な金属からなる陰極と異種金属接触腐食における貴な金属からなる陽電極を対峙させて配置することによりガルバニック電池が形成されて、その間に自然に発生する起電流を利用するものである。
【0006】
卑な金属としては、マグネシウム、亜鉛、ベリリウム、アルミニウム合金等があり、マグネシウムは−1.6ボルト程度の電位を示し、亜鉛、ベリリウム、アルミニウム合金等は−1.0ボルト程度の電位を示す。
また、貴な金属としては、黒鉛、白金、ニッケル・クロム・モリブデン合金C、チタン・ニッケル・クロム・銅・シリコン合金B、ニッケル・鉄・クロム合金825、アロイ20、ステンレス鋼、銅、銀等が一般的である。このうち、黒鉛および白金は+0.2ボルト程度の電位を示し、他の金属は0ボルト近辺の電位を示す。
本発明における両電極の材料は、これらの貴な金属および卑な金属のうち0.7ボルト以上の起電力を発生させることのできる組み合わせを適宜に選択し使用することができる。
【0007】
また本発明に使用する陽電極及び陰極は、オープンセル構造を採用している。
こうすることにより、液体が流動しやすいと共に陽電極の表面積を単に平面的なものに比べ格段に広くすることができるので、液体中の多数の細菌を接触させることができ、殺菌効率を向上させることができる。
なお、陽電極は汎用材料の銅または銅合金でよく、陰電極をマグネシウムとしたものとの組み合わせは、高くて安定した起電力を得ることができる。
【0008】
以下、具体的な構造を実施例に基づき説明する。
【0009】
図1は本発明の第1の実施例を示す。図2は図1の断面AAを、従来の装置(特願2002−294261)のもの(左側)に較べて、右側に示す。
【0010】
本発明に使用する殺菌液生成装置1は、図1に示すように筒状に形成され両側の端面3,4が解放されたパイプ状及び筒編状陰電極2、当該陰電極2の内部に非接触状態に配置されるオープンセル構造の陽電極5で構成されている。
【0011】
陰電極2は、パイプ状及び筒編状両者ともにマグネシウム製であり、陽電極5はオープンセル構造で形成され、銅或いは銀を5〜30%含んだ銅合金で形成される。
以前の装置断面(図2左図)と較べるとわかるように、本出願の装置(図2右側)は、陰極マグネシウムパイプの内側に筒編マグネシウム合金9を付け加える。マグネシウムパイプを含めて、陰極全体を筒編マグネシウム合金で構成してもよい。筒編マグネシウム合金陰極9を加えることにより、陰極の表面積を増加させることができ、電位の変化は望めないが、電流値を増加させることになり、殺菌効果は電流値に依存するため、殺菌効果を大幅にあげることができる。また筒編マグネシウム合金の線条径を変えることにより、殺菌効果の持続時間を制御が可能になり、本殺菌装置の有効期間の判断が可能になる。また、電流値をあげるためには、筒編マグネシウム合金を、1層から、3層、4層に増やすことができる。図2は筒編マグネシウム合金の3例の写真である。
なお、陽電極5の作製方法としては正規材料の成型品に換え、芯材にウレタンスポンジや金属繊維を束子状にして所定形状とした上で各種メッキにより銅或いは銀を5〜30%含んだ銅合金をコーティングするようにしても良い。
【0012】
また、陰電極2と陽電極3間を非接触状態とするには、図4に表すA−A拡大断面図に示すように樹脂製等の適宜のスペーサ7を用いて間隙部6を設けても良いが、図5に示すように樹脂製等の網状絶縁シート8を介在させるようにしても良く、この場合は殺菌液生成装置1の外径寸法が大きく採れない場合に好適なものになる。
【0013】
図6は第2の実施例を表したものであり、この実施例における殺菌液生成装置11は陰電極12の両側の開口部13,14にメッシュ状等に形成された複数の通液口17を有するカバー部材19,19をねじ構造等で着脱自在に取り付けることができるようにした点が第1の実施例と異なっている。この構成によれば陽電極15の移動を防止することができる。
【0014】
図7は第3の実施例を示し、この実施例における殺菌液生成装置21は第2の実施例に表した片方のカバー部材を濾過構造としたものである。即ち、陰電極22における片方の開口部24の端部には濾過部材26を収納した濾過付きカバー部材29がねじ構造等で着脱自在に取り付けられており、液体中の不純物を吸着できるようになっている。
なお、濾過部材としては中空糸構造や活性炭等の適宜の物を使用してよい。
【0015】
これまで説明した第1〜第3の実施例は、各種の貯液槽や貯液用の器内に浸漬させて使用したり、陰電極における片方の端部から他方の端部に向かって液体を流動させる液路中に配置して使用する。
この使用状態において、陰電極2及び陽電極5の両極間には液体を介してガルバニック電池が形成されて1.5ボルト程度の起電力が発生する。
液体中に存在する菌体は、マイナスイオンに帯電しているため陽電極5側に引き寄せられ接触するが、0.7ボルト以上の電圧に接触することになるので上述の通り死滅することになる。
【0016】
なお本発明は、循環流路中に配置することも可能であり、好ましい使用例として図8で表す第4の実施例について説明する。
【0017】
本実施例に使用する循環流路を有する器体は、特開平9−108658号公報で表される小型簡易浄水器であり、本実施例における殺菌液生成装置付き小型簡易浄水器30も同様に図8に示すように概ね、容量が1.5リットル程度の容器部31、蓋部32で構成され、蓋部32には注水口35、シールキャップ36、撹拌駆動装置37、撹拌翼38が設けられ、撹拌翼38の下方を覆うようにミネラル含有材40と濾過材41が収納された円筒体39が蓋部32に着脱自在に取り付けられる。また、円筒体39の下部には吸水口43を有する可撓性材料の吸水チューブ42が取り付けられている。なお、44は吸水口43の吐出口であり撹拌翼38に対向する円筒体39に形成されている。そして、容器部31と蓋部32間には蓋ロック装置33が設けられシールリング34で密封できるようになっている。
【0018】
以上の構成からなる小型簡易浄水器30において、容器部31内の液体中に浸積状態の撹拌翼38を撹拌駆動装置37により回転させると、円筒体39内の液体が吐出口44から容器部31内に吐出されることと連動して円筒体39の下部に設けられた吸水チューブ42の吸水口43から容器部32内の液体が濾過材41及びミネラル含有材40を介して撹拌翼38近傍まで流入されることにより、容器部内の液体は濾過作用付きの循環を繰り返して純度の良い浄水を得られ、さらにミネラル含有材により天然水や自然水に相当するミネラル水を得られることになる。
【0019】
ここで、円筒体39に収容されるミネラル含有材40の上部に上述した本発明の第1の実施例及び第2の実施例による殺菌液生成装置45を配置すると、殺菌効果にも優れたものとすることができる。なお本実施例は、第1の実施例よる殺菌液生成装置を配置したものである。
【0020】
以上のように本発明による殺菌液生成装置の殺菌力は高く、上水、牛乳、果汁等の各種の飲料用液体に用いることができる。
【0021】
また、本発明は上述した飲料用に限らず、汚染された或いは汚染しやすい装置や容器或いは循環液路中に応用することができ、例えば24時間用を含む風呂、観賞用・養魚用の水槽、プール、その他各種の貯液槽に用いられる液体の殺菌に適用することができると共に、その形態や構造も上記実施例に限らず用途に合わせて変形して実施することができる。
【0022】
【発明の効果】
本発明によれば、液体中に浸積するように異種金属接触腐食における卑な金属からなる陰極と異種金属接触腐食における貴な金属からなる陽電極を対峙させて配置することによりガルバニック電池が形成され、その間に自然に発生する起電流を利用するものであるため、特別な電源が不要となって簡単な構造となると共に、陰極、陽極両者ともにオープンセル構造としたため、高度の殺菌効率を得られる利点がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a germicidal liquid generating device and a small and simple water purifier with a germicidal liquid generating device, which can be used for various liquids and is particularly suitable for beverages.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, sterilization techniques for liquids such as foods have played an important role, and various sterilization methods have been implemented.
Typical methods include the use of chemicals, heating, pressurization, and irradiation with ultraviolet rays, radiation, and ultrasonic waves. In some cases, the method of heating and pressurizing is clean, but there are disadvantages in that applied objects are limited, large-scale equipment is required, and energy consumption is large.
In addition, a filtration type water purifier that adsorbs various bacteria using an activated carbon or a hollow fiber filter is also known. However, there is an advantage that the structure is simple, but there is no bactericidal action itself. There are also inconveniences such as the fact that bacterial cells attached to the surface of a filter or the like multiply and clog.
On the other hand, an electrochemical sterilization method using an electron transfer reaction between cells and electrodes has been developed by recent research, and a water purifier using a low-voltage sterilization method has been known. That is, as shown in FIG. 9, a positive electrode (activated carbon fiber) 52 and a negative electrode 53 are installed below the water purifier 51 and are immersed in the injected raw water (tap water). When a potential of 0.5 volts is applied, the cells present in the raw water during that time are killed, and purified water is generated by passing water through activated carbon fibers. According to this method, sterilization and propagation can be suppressed with a safe and relatively simple structure, but a sterilization apparatus having a further simple structure has been desired.
In addition, there are various small and simple water purifiers in which a filter material is immersed in a liquid storage container. However, these water purifiers merely adsorb germs to the filter material, and further improvement of water quality is beneficial for users. It is considered to be.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and has an object to provide a germicidal solution generation device and a small and simple water purifier with a germicidal solution generation device which can realize safe and effective liquid sterilization with a simple configuration. I do.
[0004]
[Means for Solving the Problems]
As a result of intensive studies to solve the above problems, in the present invention, both ends made of a base metal in dissimilar metal contact corrosion capable of generating an electromotive force of 0.7 volt or more by interposing a liquid are released. A sterilizing liquid generator consisting of a cylindrical negative electrode and a positive electrode made of a noble metal in the dissimilar metal contact corrosion of an open cell structure disposed in a non-contact state inside the negative electrode is interposed between the two electrodes. It has been found that a large number of cells in the liquid can be killed by contacting the positive electrode with an open cell structure over a wide area, so that it is suitable for sterilization.
In this case, it is preferable that the cathode is made of magnesium, and it is most preferable that the cathode has an open cell cylindrical structure made of a thin magnesium wire.
Further, it is preferable that the positive electrode is made of copper or a copper alloy because it is difficult to dissolve into a liquid and is a general-purpose material, so that the cost is low.
It is more preferable to provide a filtration device below the negative electrode because foreign substances in the liquid can be adsorbed.
Further, since the present sterilizing apparatus can be formed in a small size, it can be mounted in various liquid circulating apparatuses such that the liquid can be passed.
Therefore, it can be mounted on the liquid forced circulation flow path in which the filtration unit is accommodated in the liquid storage container, and can be finished as a small and simple water purifier with improved water quality.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The principle of generating the bactericidal action in the present invention is that, as shown in the above-mentioned electrochemical sterilization method, since the cells present in the liquid are negatively (-) charged, the cells come into contact with the positive electrode. It is based on the theory that the viable cell rate sharply decreases when the voltage of 0.7 volt or more is applied in this state and a voltage of 0.7 volt or more is applied in this state (the cells are killed). Instead of using a power source such as a dry cell, a cathode made of a base metal in dissimilar metal contact corrosion and a positive electrode made of a noble metal in dissimilar metal contact corrosion are arranged so as to face each other so as to be immersed in the liquid. As a result, a galvanic battery is formed, and an electromotive current naturally generated during the galvanic battery is used.
[0006]
Examples of the base metals include magnesium, zinc, beryllium, and aluminum alloy. Magnesium has a potential of about -1.6 volts, and zinc, beryllium, and aluminum alloy have a potential of about -1.0 volt.
Noble metals include graphite, platinum, nickel-chromium-molybdenum alloy C, titanium-nickel-chromium-copper-silicon alloy B, nickel-iron-chromium alloy 825, alloy 20, stainless steel, copper, silver, etc. Is common. Among them, graphite and platinum show a potential of about +0.2 volt, and other metals show potentials near 0 volt.
As a material for both electrodes in the present invention, a combination capable of generating an electromotive force of 0.7 volt or more among these noble metals and base metals can be appropriately selected and used.
[0007]
The positive electrode and the cathode used in the present invention adopt an open cell structure.
By doing so, the liquid is easy to flow and the surface area of the positive electrode can be much larger than that of a flat electrode, so that a large number of bacteria in the liquid can be brought into contact and the sterilization efficiency can be improved. be able to.
The positive electrode may be a general-purpose material such as copper or a copper alloy, and a combination of the negative electrode with magnesium may provide a high and stable electromotive force.
[0008]
