Description

【０００１】
【発明の属する技術分野】
本発明は、酸化還元電位の低い還元水を生成する浄水器及び浄水方法に関する。
【０００２】
【従来の技術】
従来、浄水器では、水道水、井戸水等を不純物を採取するフィルタで濾過し、さらにカーボンフィルタにより汚染物質等を除去し、これを飲用に供している。また日常飲用している水道水には、浄水場で殺菌のために加えられる塩素のため、水の味を悪くし、さらには残留塩素と水中の有機物が化合してトリハロメタン等の人体に悪影響を及ぼす物質が生成されることが周知の事実となりつつある。
【０００３】
ここで、水の改質方法として、特許第２６１１０８０号、特許第２６１５３０８号及び特許第２６２３２０４号等に係る各公報に還元水を得る方法が開示されている。かかる方法は、水中に第１、第２、第３の電極を配置し、この内第１の電極と第２の電極との間に高周波の交流電圧を印加するとともに、第３の電極を接地し、水を電気分解して酸化還元電位の低い還元水を作るものである。
【０００４】
上記電極に交流を印加すると、第１の電極と第２の電極では金属イオンの溶出と水素ガスの発生、第３の電極では水素ガスと酸素ガスの発生が起こり、また、第３の電極で発生する酸素は大気中に放出され溶存酸素量が増加する。一方、上記反応によって生じた水素は過飽和に液中に溶け込み、この結果、酸素に比べて還元体である水素が増加し酸化還元電位が低下するものと考えられている。上記水の改質方法によれば、酸化還元電位が低く、活性水素を多く含んだ良好な還元水が生成できる。
【０００５】
【特許文献１】
特開２００２−１８４２９号公報
【０００６】
一方、上記特許文献１には図５に示すように、水中のゴミや塩素を除去するカートリッジ４２と、容器４３内の電極４５により水をアルカリイオン水に変える電解水生成装置４４とを有し、さらにこれらの間に、光触媒装置４６（紫外線ランプ４７の周りに二酸化チタンを内臓した導水管を有する）を配置した飲料用浄水器が開示されている。この浄水器は、ダイオキシン、塩素化合物等を酸化分解処理し、また水中の細菌類をオゾンによって殺菌し、このオゾンを上記電解水生成装置４４で分解して無害化するとともにアルカリイオン水を生成するというものである。
【０００７】
【発明が解決しようとする課題】
さて、上記水の改質方法によれば酸化還元電位の低い水が得られるが、なお水道水などの水中には、塩素、有機物、或いは一般雑菌が多く含まれている場合があり、これらを除去しさらに良質の水を得ることが望まれている。また、上記飲料用浄水器によれば、殺菌等を行う光触媒装置と電解水生成装置とが別の容器で構成されているため装置全体が大型化、複雑化するという問題があり、またこのため浄水器の維持管理が容易ではないという問題が予想される。
【０００８】
本発明は、上記問題点に鑑みてなされたものであり、簡便に良質の還元水が得られ、併せて維持管理の容易な浄水器及びこれを用いた浄水方法を提供することを目的とする。
【０００９】
【課題を解決するための手段】
以上の技術的課題を解決するため、本発明に係る浄水器は、図１に示すように、水を蓄える浄水槽２と、オゾン発生器で発生させたオゾンを上記浄水槽２の水中に注入する手段と、上記浄水槽２に３つの電極を突入させ、この内の第１の電極２４と第２の電極２５との間に交流を印加するとともに、第３の電極２６を接地し、上記第１及び第２の電極から上記第３の電極に水を経て電流を流し、上記水を電気分解してこの水の酸化還元電位を下げて還元水を作る電解手段と、を有するものである。
【００１０】
また、本発明に係る浄水器は、上記浄水槽２として上部が開口した容器を用い、上記開口した部位を閉塞する蓋体部４に、上記注入手段及び上記第１、第２、第３の電極２４，２５，２６の一端部を固定し、この蓋体部４が閉状態のときに、上記注入手段及び上記第１、第２、第３の電極の他端部を水中に突入可能に、また上記蓋体部４が開状態のときに、上記注入手段及び上記第１、第２、第３の電極の他端部が上記浄水槽から引き上げ可能に設けられ、上記蓋体部４が開状態のときに、上記浄水槽が脱着可能に配置されたものである。
【００１１】
また、本発明に係る浄水器は、上記第１の電極、第２の電極２４，２５として何れも網体を用いる一方、上記第３の電極２６として筒体を用い、上記第３の電極の両側に上記第１及び第２の電極を配置し、この第３の電極としての筒体を上記注入手段として用いたものである。
【００１２】
本発明に係る浄水器は、上記浄水槽２をステンレス材により形成し、上記第３の電極２６と上記浄水槽２とを電気的に接続したものである。
【００１３】
本発明に係る浄水方法は、上記何れかに記載の浄水器を用い、浄水槽２の水中にオゾンを注入してオゾン処理を行った後、又はこのオゾン処理と同時に、上記浄水槽２の水中に突入した上記３つの電極２４，２５，２６により、水を電気分解して酸化還元電位を下げて還元水を作るものである。
【００１４】
【発明の実施の形態】
以下、本発明に係る浄水器の実施の形態を図面に基づいて説明する。図１乃至図４は、上記浄水器１を示したものである。この浄水器１は、水道水などの水を蓄え、これから還元水を生成する浄水槽２、この浄水槽２を載置する制御ボックス部６及び蓋体部４を有し、全体が略円筒状の形態である。
【００１５】
上記浄水器１には、上記制御ボックス部６の側部から立設された筒状の支持体８が設けられている。この支持体８内にはホース２１及び電気コード３０，３１，３２等が収納され、支持体８の上部は枢軸部９により、上記蓋体部４が開閉自在に取り付けられている。上記蓋体部４には、３つの電極２４，２５，２６が固定され、これら電極は蓋体部４と一体に移動する。制御ボックス部６は上下部が平坦面で閉塞した円筒状の容器からなり、この側部には、電源等の操作スイッチ、ランプ等が設けられた操作部１１が形成されている。
【００１６】
上記制御ボックス部６内には、ＣＰＵを中心に制御回路が設けられた制御基板部１２、エアーポンプ１４、オゾン発生機１６、高圧電源装置１８が組み込まれている。電源トランス部１０は、制御ボックス部６のコンパクト化のため別途外部に設けている。上記高圧電源装置１８は、オゾン発生機１６に高圧電気を供給する。上記制御基板部１２には制御回路として、還元水生成のための高周波交流発生回路、変調回路、クリーニング回路、タイマー回路及び、オゾンの発生を制御するオゾン制御回路などが設けられている。
【００１７】
上記３つの電極２４，２５，２６は、それぞれ一端部が上記蓋体部４の下面部に固定されている。この内、第３の電極２６は中央に、この両側には第１及び第２の電極２４，２５がそれぞれ等間隔に設けられ、かつ３つの電極が一列状に配置されている。また上記電極２４，２５は、それぞれ長方形状の網体からなり、これらはチタンに白金メッキが施されている。
【００１８】
原理的には、電気分解の効率（酸化還元電位の低下）は、電極の面積が大きいほど良くなるが、電極を上記網体とした場合には、同じ表面積の板状電極と比べて酸化還元電位の低下が大きく、良好な結果が得られている。また、網体は白金メッキの量が少なくて済む。電極に用いたチタンは耐蝕性、耐久性に優れ、また白金は表面に酸化被膜ができないため水の電気分解力が安定し、かつ水に溶け込むことがなくメンテナンスも不要である。
【００１９】
第３の電極２６には、ステンレス製の円管が用いられ、この管内には上記オゾン用のホース２１を挿通させてこれを保持している。この第３の電極２６は、電極としての機能と、注入手段としてオゾンを水中に注入する機能の両機能を兼用させ、機構の簡素化を図っている。なお、上記電極２４，２５，２６の材料としては、他に、アルミニウム、亜鉛、鉄、ステンレス、銅などの金属を用いることができる。
【００２０】
上記第１の電極２４と第３の電極２６、第２の電極２５と第３の電極２６との空間距離は等しく設定され、２０ｍｍ〜５０ｍｍの範囲としている。これら電極同士の間隔は、狭い方が電解が活発に行われるが、広くして時間をかけることにより、水素の発生が適度に行われて効率的よく水中に溶け込むことから、水の品質が良くなる。
【００２１】
なお、オゾンの注入手段として、ホース２１を第３の電極２６である円管の上端部に単に接続する形態としてもよい。また他の注入手段として、第３の電極２６を他の電極と同様な網状の形状とし、これに沿って上記ホース２１を保持してホース自体を水中に延設するような形態、あるいは別途オゾン注入用のパイプを第３の電極２６に隣接させて蓋体部４に設け、ホース２１をこれに接続する形態としてもよい。
【００２２】
図３に示すように、上記浄水槽２に蓋体部４が閉じたときには、電極２４，２５，２６及び注入パイプ２２は、浄水槽２に突入した状態となり、水の電気分解及び水中内へのオゾンの注入が可能となる。また、図４に示すように、蓋体部４を開いた状態では、蓋体部４は略垂直向きとなり電極２４，２５，２６は浄水槽２から引き上げられ横向きとなる。このとき蓋体部４は、枢軸部９に設けられたロック機構により開状態で固定され、浄水槽２の着脱が自在となる。
【００２３】
上記制御ボックス部６内のエアーポンプ１４とオゾン発生機１６との間、及びこのオゾン発生機１６と浄水槽２内との間には、空気及びオゾンを空気と共に送るための弾性を有するホース２１（シリコンホース）が連結されている。このホース２１は、上記支持体８の筒内部を経由し、枢軸部９の近傍を屈曲して通過し、蓋体部４に固定された第３の電極２６の管内に挿通保持されている。また、このホース２１の途中には、空気（或いは水）の逆流を防止するための逆止弁２３が設けられている。
【００２４】
一方、上記制御ボックス部６の制御基板１２からは、上記電極２４，２５，２６に電気を供給するための電気コード３０，３１，３２がそれぞれ出力され、これらは支持体８の内部を経由して、蓋体部４に固定された電極２４，２５，２６に接続されている。この内、第３の電極２６に接続される電気コード３２の一端は、上記浄水槽２の裏面部に電気的に接続されている。
【００２５】
上記浄水槽２はステンレス製の容器からなる。この浄水槽２は、上記制御ボックス部６の上部面に載置された状態に置かれ、着脱可能である。浄水槽２の容器は、上記第３の電極２６とともにそれ自体が電極を兼ねている。このように浄水槽２自体を電極とすることで、第３の電極２６の面積が広くなり効率的に電気分解が行われる。また、浄水槽２の側面の下部には給水栓２８が設けられ、側面の上下向にはスリット状の窓部２９が設けられており、所定の目盛により水量が確認できるようにしている。この窓部の他の形態として、一定の間隔をおいて、各目盛りに対応する位置にそれぞれ孔状の窓を設けることとしてもよい。
【００２６】
電気分解に際しては、従来技術の欄で示したように、第１の電極２４と第２の電極２５との間に高周波の交流（３０ＫＨｚ〜５０ＫＨｚ）の電圧（１０Ｖ〜５０Ｖ）を印加するとともに、第３の電極２６を接地し、上記第１の電極２４及び第２の電極２５から第３の電極２６に水を経て直流電流を流し、水を電気分解してこの水の酸化還元電位を下げて還元水を作る。
【００２７】
この電気分解処理の時間は選択により１時間、１時間３０分、２時間と区別される。この時間は、原則的には水量が多いと長く設定するが、利用者は任意に設定可能である。また、クリーニング回路により、第３の電極（及び浄水槽２）に定期的に低周波の交流電位が加えられ、この電極に付着物が付くのを防止し電極の保守を容易にしている。この浄水器１には、通常水道水が用いられるが、活性炭（カーボン）を包含するカーボンフィルタ等で浄化した水を用いるのは何ら差し支えない。
【００２８】
上記浄水器１は、浄水槽２内で、オゾンを発生して殺菌などを行うオゾン処理と、水を電気分解して還元水を作る電解処理とを行う。浄水の手順は、先ずオゾン処理により、浄水槽２内の水にオゾンを注入し、塩素、トリハロメタンなどを除去し、また脱臭、殺菌を行う。このオゾン処理の時間として、約５〜１０分程度要する。この後、電解処理により上記オゾン処理した水を交流電気分解し、活性水素の豊富な抗酸素水を作る。
【００２９】
また、この浄水器１において、オゾン処理と、電解処理とを同時、並行的に行わせることとしてもよい。この場合には、最初の約５〜１０分はオゾン処理と電解処理が並行して行われ、その後は電解処理のみが行われることになる。この並行処理により、時間の短縮が図れる。また、浄水器１で電解処理のみを行うようにすることとしてもよい。
【００３０】
上記浄水器１では、一の浄水槽２で、オゾン処理による酸化反応と電解処理による還元反応とを行っているため、酸化還元反応を連続して効果的に行うことができる。オゾン処理を行った水を電解処理した場合、水質（水道水、雨水、川水等）の如何に係わらず一律に酸化還元電位の低い浄水が得られることが確認されている。また、オゾン処理により水のＰＨは酸性に移行するが、電解処理では逆にアルカリ性に移行し、結果的には人体に影響のない良質の中性の水が得られる。
【００３１】
上記浄水器１の具体的利用方法は、先ず利用者は浄水器１の蓋体部４を開けて、浄水器１から浄水槽２を取り出し、この浄水槽２を水道蛇口まで持っていき必要な量の水を注ぎ込む。そしてこの浄水槽２を、元の浄水器１の制御ボックス部６の上に装着し、蓋体部４を閉塞して電極２４，２５，２６を水中に突入させる。次に利用者は、操作部１１を操作して電源を投入し、また必要に応じて操作部１１を操作して所望する還元の時間（１時間、１時間３０分、２時間）を選択する。この選択操作により、該当する時間を示す表示ランプが点灯する。また、還元処理中は操作部１１の還元ランプが点灯し、これが終了すれば完了ランプが点灯する。
【００３２】
さて、電源の投入により、上記制御基板１２のオゾン制御回路は、高圧電源装置１８及びオゾン発生器１６を駆動してオゾンを発生させ、同時にエアーポンプ１４を駆動する。すると、上記発生したオゾンは、エアーポンプ１４から送られる空気とともにホース２１を経由して第３の電極２６の管内を通過し、この下端部から水中に放出注入される。なお、ホース２１の途中に設けた逆止弁２３により空気の逆流が防止される。
【００３３】
上記空気と共に水中に放出されたオゾンは、水中に拡散される。この間に、オゾンは水中の塩素、トリハロメタン、及び有機物を除去、分解するとともに、水中の大腸菌、一般細菌等を殺菌し脱臭し、またミネラル分を増加する。水中にミネラルが多くなると、ミネラルのイオンに水素が吸着して酸化還元電位を下げ、加えて水素が分解し難くなって低電位の持続時間が長くなる。水中の塩素は酸化物として、還元電位の上昇をもたらすが、上記オゾンの作用により水中から塩素、有機物がなくなると還元水生成の際の還元作用が増大し、また容器にカルキが付着しなくなる。
【００３４】
上記オゾン処理の後は電解処理が行われる。この電解処理では、上記制御基板１２から浄水槽２の電極２４，２５に高周波の交流を印加し、これにより第１及び第２の電極２４，２５から第３の電極に電流が流れて、水の電気分解が行われる。この電気分解により、還元電位が低下し、活性水素の豊富な抗酸素水が生成される。この生成された還元水は、浄水槽２に設けられた給水栓２８を操作してコップ等に移して飲料に供する。
【００３５】
したがって、上記浄水器１によれば、水中の雑菌が殺菌され衛生的であり、かつ、有機物が分解沈殿し、有害なトリハロメタンなども除去できて安全な水が得られ、また酸化還元電位が低く、活性水素、溶存酸素を多く含んだ良好な還元水が得られる。さらに上記浄水器１は、殺菌された衛生的でかつオゾン処理と電解処理を同じ浄水槽２内で行わせるようにしたから、装置がコンパクトかつ簡易な形状に構成されて経済性にも優れ、また浄水槽の着脱が容易に行え、維持管理が容易である。
【００３６】
【発明の効果】
以上説明したように、本発明に係る浄水器によれば、オゾンを浄水槽の水中に注入する手段と、浄水槽に３つの電極を突入させて水を電気分解して還元水を作る電解手段とを有するものとしたから、水中の雑菌が殺菌されトリハロメタンなども除去できた衛生的かつ安全で、酸化還元電位が低い還元水が得られるとともに、機器がコンパクトかつ簡易な形状に構成されて維持管理性および経済性にも優れるという効果を奏する。
【００３７】
また、本発明に係る浄水器は、浄水槽として上部が開口した容器を用い、開口した部位を閉塞する蓋体部に、注入手段及び各電極を固定し、蓋体部が開状態のときに、浄水槽が脱着可能に配置された構成を採用したから、機器が簡易な形状に構成されるとともに浄水槽の着脱が容易に行え、維持管理が容易であるという効果がある。
【００３８】
また、本発明に係る浄水器は、第１の電極、第２の電極として何れも網体を用いる一方、第３の電極の筒体を注入手段として用いたものとしたから、機器が簡易な構成で形成され、また浄水槽をステンレス材により形成して第３の電極と電気的に接続したことから、電解処理の効率化が図れるという効果がある。
【００３９】
本発明に係る浄水方法は、浄水槽でオゾン処理を行った後、又はこのオゾン処理と同時に、浄水槽で電解処理を行うこととしたから、衛生的かつ安全で、酸化還元電位が低い還元水が得られるとともに、機器の維持管理が容易であり、しかも水質の如何に係わらず一律に酸化還元電位が低い浄水が得られるという効果を奏する。

[0002]
[Prior art]
Conventionally, in a water purifier, tap water, well water, and the like are filtered by a filter that collects impurities, and further, contaminants and the like are removed by a carbon filter, which is used for drinking. In addition, tap water that is drunk daily is chlorine added for sterilization at the water purification plant, so the taste of the water deteriorates, and the residual chlorine and organic substances in the water combine to adversely affect the human body such as trihalomethane. It is becoming a well-known fact that an effecting substance is produced.
[0003]

On the other hand, it is considered that hydrogen generated by the above reaction dissolves into the liquid in a supersaturated state, and as a result, hydrogen as a reductant increases and the redox potential decreases as compared with oxygen. According to the water reforming method, it is possible to generate good reduced water having a low oxidation-reduction potential and containing a large amount of active hydrogen.

[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a water purifier according to the present invention will be described with reference to the drawings. 1 to 4 show the water purifier 1 described above. This water purifier 1 has a water purifying tank 2 that stores water such as tap water and generates reduced water therefrom, a control box portion 6 on which the water purifying tank 2 is placed, and a lid portion 4, and the whole is substantially cylindrical. It is a form.
[0015]
The water purifier 1 is provided with a cylindrical support 8 erected from the side of the control box 6. A hose 21 and electric cords 30, 31, 32 and the like are accommodated in the support 8, and the lid 4 is attached to the upper part of the support 8 by a pivot 9 so as to be freely opened and closed. Three electrodes 24, 25, and 26 are fixed to the lid body portion 4, and these electrodes move integrally with the lid body portion 4. The control box portion 6 is formed of a cylindrical container whose upper and lower portions are closed with a flat surface, and an operation portion 11 provided with operation switches such as a power source and a lamp is formed on this side portion.
[0016]
In the control box unit 6, a control board unit 12, an air pump 14, an ozone generator 16, and a high-voltage power supply device 18 provided with a control circuit centering on the CPU are incorporated. The power transformer 10 is provided separately outside for the compact control box 6. The high voltage power supply 18 supplies high voltage electricity to the ozone generator 16. The control board unit 12 is provided with a high-frequency alternating current generation circuit for generating reduced water, a modulation circuit, a cleaning circuit, a timer circuit, an ozone control circuit for controlling the generation of ozone, and the like as control circuits.
[0017]
One end of each of the three electrodes 24, 25, 26 is fixed to the lower surface of the lid body 4. Among them, the third electrode 26 is provided at the center, the first and second electrodes 24 and 25 are provided at equal intervals on both sides, and the three electrodes are arranged in a line. The electrodes 24 and 25 are each made of a rectangular mesh, and these are plated with platinum on titanium.
[0018]
In principle, the efficiency of electrolysis (decrease in redox potential) increases as the area of the electrode increases. However, when the electrode is made of the above-mentioned network, the redox is reduced compared to the plate electrode having the same surface area. The decrease in potential is large and good results are obtained. In addition, the net body requires a small amount of platinum plating. Titanium used for the electrode is excellent in corrosion resistance and durability, and platinum cannot form an oxide film on its surface, so that the electrolysis power of water is stable, and it does not dissolve in water, and maintenance is not required.
[0019]
As the third electrode 26, a stainless steel circular tube is used, and the ozone hose 21 is inserted into and held in the tube. The third electrode 26 has both a function as an electrode and a function of injecting ozone into water as an injection means, thereby simplifying the mechanism. In addition, as materials for the electrodes 24, 25, and 26, other metals such as aluminum, zinc, iron, stainless steel, and copper can be used.
[0020]
The spatial distances of the first electrode 24 and the third electrode 26, and the second electrode 25 and the third electrode 26 are set to be equal to each other and range from 20 mm to 50 mm. The narrower the gap between the electrodes, the more active the electrolysis, but the longer the time is spent, the more hydrogen is generated and the water efficiently dissolves in the water. Become.
[0021]
As a means for injecting ozone, the hose 21 may be simply connected to the upper end portion of the circular tube that is the third electrode 26. As another injection means, the third electrode 26 has a net-like shape similar to the other electrodes, the hose 21 is held along the third electrode 26, and the hose itself is extended in water, or separately ozone. An injection pipe may be provided adjacent to the third electrode 26 in the lid body portion 4 and the hose 21 may be connected thereto.
[0022]
As shown in FIG. 3, when the lid 4 is closed to the water purification tank 2, the electrodes 24, 25, 26 and the injection pipe 22 enter the water purification tank 2, and electrolyze water and enter the water. It is possible to inject ozone. Moreover, as shown in FIG. 4, in the state which opened the cover part 4, the cover part 4 becomes substantially perpendicular | vertical direction, and the electrodes 24, 25, and 26 are pulled up from the water purification tank 2, and become sideways. At this time, the lid part 4 is fixed in an open state by a lock mechanism provided in the pivot part 9, and the water purification tank 2 can be attached and detached freely.
[0023]
Between the air pump 14 and the ozone generator 16 in the control box 6 and between the ozone generator 16 and the water purification tank 2, an elastic hose 21 for sending air and ozone together with air is provided. (Silicon hose) is connected. The hose 21 passes through the inside of the cylinder of the support 8, passes through the vicinity of the pivot 9, and is inserted and held in a tube of the third electrode 26 fixed to the lid 4. Further, a check valve 23 for preventing a backflow of air (or water) is provided in the middle of the hose 21.
[0024]
On the other hand, the control board 12 of the control box unit 6 outputs electric cords 30, 31, and 32 for supplying electricity to the electrodes 24, 25, and 26, respectively, which pass through the inside of the support body 8. The electrodes 24, 25, and 26 are fixed to the lid body 4. Among these, one end of the electric cord 32 connected to the third electrode 26 is electrically connected to the back surface portion of the water purification tank 2.
[0025]
The water purification tank 2 is made of a stainless steel container. The water purification tank 2 is placed on the upper surface of the control box 6 and is detachable. The container of the water purification tank 2 itself serves as an electrode together with the third electrode 26. As described above, by using the water purification tank 2 itself as an electrode, the area of the third electrode 26 is increased, and electrolysis is efficiently performed. A water faucet 28 is provided at the lower part of the side surface of the water purification tank 2, and a slit-shaped window 29 is provided vertically on the side surface so that the amount of water can be confirmed by a predetermined scale. As another form of this window part, it is good also as providing a hole-shaped window in the position corresponding to each scale with a fixed space | interval.
[0026]
In electrolysis, as shown in the prior art column, a high-frequency alternating current (30 KHz to 50 KHz) voltage (10 V to 50 V) is applied between the first electrode 24 and the second electrode 25, and The third electrode 26 is grounded, a direct current is passed from the first electrode 24 and the second electrode 25 to the third electrode 26 through water, and the water is electrolyzed to lower the redox potential of this water. Make reduced water.
[0027]
The time of this electrolysis process is distinguished from 1 hour, 1 hour 30 minutes, and 2 hours depending on selection. In principle, this time is set longer when the amount of water is large, but the user can set it arbitrarily. In addition, the cleaning circuit periodically applies a low-frequency AC potential to the third electrode (and the water purification tank 2), and prevents adhesion of the electrode to facilitate maintenance of the electrode. Normally, tap water is used for the water purifier 1, but it is possible to use water purified by a carbon filter containing activated carbon (carbon) or the like.
[0028]
The water purifier 1 performs, in the water purification tank 2, ozone treatment for generating ozone to sterilize and electrolytic treatment for electrolyzing water to produce reduced water. The procedure of water purification is to first inject ozone into the water in the water purification tank 2 by ozone treatment to remove chlorine, trihalomethane, etc., and to deodorize and sterilize. This ozone treatment takes about 5 to 10 minutes. Thereafter, the ozone-treated water is electrolytically electrolyzed by electrolytic treatment to produce anti-oxygen water rich in active hydrogen.
[0029]
Moreover, in this water purifier 1, it is good also as performing ozone treatment and electrolytic treatment simultaneously and in parallel. In this case, the ozone treatment and the electrolytic treatment are performed in parallel for the first about 5 to 10 minutes, and only the electrolytic treatment is performed thereafter. This parallel processing can shorten the time. Moreover, it is good also as performing only an electrolytic process with the water purifier 1. FIG.
[0030]
In the said water purifier 1, since the oxidation reaction by ozone treatment and the reduction reaction by electrolytic treatment are performed in one water purification tank 2, an oxidation reduction reaction can be performed effectively continuously. It has been confirmed that when the ozone-treated water is subjected to electrolytic treatment, purified water having a low oxidation-reduction potential can be obtained regardless of the water quality (tap water, rain water, river water, etc.). In addition, the pH of water shifts to acidic by ozone treatment, but reversely shifts to alkaline by electrolytic treatment, and as a result, high-quality neutral water that does not affect the human body is obtained.
[0031]
The specific usage method of the water purifier 1 is that the user first needs to open the lid 4 of the water purifier 1, take out the water purifier 2 from the water purifier 1, and bring the water purifier 2 to the water tap. Pour a quantity of water. And this water purification tank 2 is mounted | worn on the control box part 6 of the original water purifier 1, the cover body part 4 is obstruct | occluded, and the electrodes 24, 25, and 26 are plunged into water. Next, the user operates the operation unit 11 to turn on the power, and also operates the operation unit 11 as necessary to select a desired reduction time (1 hour, 1 hour 30 minutes, 2 hours). . By this selection operation, a display lamp indicating the corresponding time is turned on. During the reduction process, the reduction lamp of the operation unit 11 is turned on, and when this is completed, the completion lamp is turned on.
[0032]
Now, when the power is turned on, the ozone control circuit of the control board 12 drives the high voltage power supply device 18 and the ozone generator 16 to generate ozone, and simultaneously drives the air pump 14. Then, the generated ozone passes through the tube of the third electrode 26 through the hose 21 together with the air sent from the air pump 14, and is discharged and injected into the water from this lower end portion. The check valve 23 provided in the middle of the hose 21 prevents air backflow.
[0033]
The ozone released into the water together with the air is diffused in the water. During this period, ozone removes and decomposes chlorine, trihalomethane, and organic substances in water, sterilizes and deodorizes E. coli and general bacteria in water, and increases mineral content. When minerals increase in water, hydrogen is adsorbed to mineral ions to lower the oxidation-reduction potential, and in addition, hydrogen becomes difficult to decompose and the duration of the low potential is prolonged. Chlorine in water causes an increase in reduction potential as an oxide. However, when chlorine and organic substances disappear from the water due to the action of ozone, the reduction action during the production of reduced water increases, and the chalk does not adhere to the container.
[0034]
After the ozone treatment, electrolytic treatment is performed. In this electrolytic treatment, high-frequency alternating current is applied from the control substrate 12 to the electrodes 24 and 25 of the water purification tank 2, whereby current flows from the first and second electrodes 24 and 25 to the third electrode, Is electrolyzed. By this electrolysis, the reduction potential is lowered and anti-oxygen water rich in active hydrogen is generated. The generated reduced water is moved to a cup or the like by operating a water tap 28 provided in the water purification tank 2 and used for a beverage.
[0035]
Therefore, according to the water purifier 1, germs in the water are sterilized and sanitary, and organic matter is decomposed and precipitated, harmful trihalomethane can be removed and safe water is obtained, and the redox potential is low. Good reduced water containing a large amount of active hydrogen and dissolved oxygen can be obtained. Furthermore, since the water purifier 1 is sterilized and sanitized, and the ozone treatment and the electrolytic treatment are performed in the same water purification tank 2, the apparatus is configured in a compact and simple shape and is excellent in economic efficiency. Moreover, the water tank can be easily attached and detached, and maintenance is easy.
