Description

【０００１】
【産業上の利用分野】
この発明は、水道水を原水として使用し電気分解する電解水生成装置に関するものである。更に詳述すると、所望によって、飲料に供する陰極水を主として吐水するものと、消毒や殺菌用洗浄用水などに供する強い陽極水を主として吐水するものを自在に切り換えて生成する電解水生成装置に関する。
【０００２】
【従来の技術】
図３に示す電解水生成装置において、電解槽１は、電解槽内を隔膜９によって陰極室１１と陽極室１２に分け、夫夫の室内に電極１０、１０を挿入し、陰陽極室内に供給した原水を電極間に印加した直流電流の通電によって電気分解することにより陰極室に陰極水を、陽極室に陽極水を電解生成するものである。
【０００３】
飲料に供する陰極水を主として吐水する装置にあっては、飲料水として好ましい水質を得るため、つまり、電解槽供給前の原水中に含まれる飲料に不適な成分、例えば、臭気やカルキ、汚濁成分などの微細不純物や細菌などを取り除くため、電解槽流入前に浄水器１５を取り付け、装置内外の水道の蛇口１６で開閉して得られる水道水などの原水を浄水器の流入口１７に供給すると共に、流出口１８から流出させ、浄水器１５を通過した原水のみを給水管１９を介して電解槽１に流入するように構成している。
【０００４】
上記浄水器は上記のように臭気やカルキなどの飲料に不適な化学成分を取り除く吸着作用と汚濁物質や細菌などを取り除く濾過作用を効率的に行うため、夫夫に最適な部材をもって構成されている。すなわち、この目的の浄水器は水道水中の塩素などを除去する銀イオンを含む粒状の活性炭に亜硫酸カルシウムなどを層状に構成して吸着剤としたものに、更に、中空糸からなる濾過部材を通す方法が行われている。しかも上記浄水器は原水が多量に通過して浄水能力が低下した場合、容易に交換できるようにカートリッジとして構成し、能力の低下に従って浄水器自体を交換する。
【０００５】
従来、上記陰極水は健康に好ましい作用をする水として主に飲料水として使われる一方、陽極水はアストリンゼン水などとして使われてきた。陽極水は上記陰極水の使用に較べるとその使用量は少なく陽極水はそのまま排水される場合が多い。
【０００６】
ところが、水道水に含まれる塩素および塩素イオン自体が電解槽供給前の原水中に電解質としてＮａＣｌ、ＫＣｌなどのハロゲン化合物を一定の割合で添加して、電解槽で電気分解すると、電解質を構成するアニオンは陽極室に移動する。この結果、陽極室にはＨＣｌＯ、ＣｌＯ^-などアニオンを多量に含んだ低いｐＨの陽極水が得られる。この水には消毒および殺菌効果があるため、消毒や殺菌用洗浄用水として重宝される。
【０００７】
このような消毒および殺菌効果のあるアニオンを多量に含んだ陽極水を主に得るための電解装置では、陽極水は飲料に適さず、しかも上記のように陽極水を得るのが目的で陰極水は通常排水されるので、少なくとも陽極水を吐水する際には、原水を上記浄水器へ通過させる必要はない。
【０００８】
このため、飲料水としての陰極水を得るときは水道水などの原水を浄水器に通過するようにし、主として殺菌に効果のある陽極水を得るときは浄水器をバイパスさせて、原水を直接電解槽に供給することが考えられる。例えば、特開平６−１５４７５５号公報に開示された図４に示す装置においては、電解槽１の上流側に設けた浄水器２に対して切換え手段６を設けると共に、上記切換え手段を操作することにより、電解槽への原水を供給する際、浄水器を通過する場合と非通過する場合が選択できるようにしている。
【０００９】
すなわち、上記装置においては、飲料用としての陰極水を得る場合には、切換え手段６により原水を浄水器２を通過させて電解槽１に供給し、また洗浄や殺菌用の陽極水を必要とする場合には、切換え手段６により原水を通過させることなくバイパス流路４を通して直接電解槽に原水を供給するものである。
【００１０】
この浄水器２は浄化手段として、その筐体内部に活性炭７が充填されている。浄水器の上流側に位置する給水管３と電解槽１との間にバイパス流路４を設けると共に、給水管３とバイパス流路４との分岐部５に三方弁からなる切換え手段６を設け、（ａ）水道水を浄水器を介して電解槽に供給したり、（ｂ）水道水を浄水器を通過させることなく直接電解槽に供給したりする。
【００１１】
上記装置においては、飲料用の陰極水を必要とする場合には、図５（ａ）に示すように切換え手段６である三方弁を原水が給水管３から浄水器の流入口に原水が流通するように位置させ、原水を一旦浄水器２で浄化した後電解槽で陰極水を生成させる。また、洗浄や殺菌性の陽極水を使用する場合には図５（ｂ）に示すように、原水が給水管３からバイパス流路４に供給するように位置させ、原水を浄化器２を通過させることなく、バイパス流路４を通じて直接電解槽に供給して電解槽で陽極水を生成する。この結果、所望の水が得られると共に、陽極水を得るときは浄水器を通過させないので、浄水器の寿命を延長することができる。
【００１２】
【発明が解決しようとする課題】
ところが上記方法で、陽極水を吐水するため原水が浄水器を通らないように給水管から電解槽に直接流水するようにすると、原水は浄水器を通らないだけ流通抵抗が減少して電解槽に供給される原水の流量が増加する。
【００１３】
陽極水を主に得ようとする場合、とりわけ原水中に含まれている塩素イオンや塩素を利用して消毒や殺菌効果のある殺菌用洗浄用水を得ようとする場合、供給水量を絞り強力な電解を行うことにより始めて所望の陽極水が得られる。つまり、図４に示した単に切換え手段を切り換える従来法においては、陽極水を主に得る場合は水量を自動的に少なくしなければならない。このため、改めて、原水の供給側や吐水側に水量制御手段を設けるか、電解槽の陰陽極に印加する電流を供給水量に合わせて自動的に増大する手段を設けなければならず甚だ煩わしい。
そこで本発明は陽極水を主に得る場合には電解槽に供給する水量を自動的に少なくすることにより、上記課題を解決しながら浄水器の寿命を延長させうる殺菌用洗浄用水を簡単に得る装置を提供しようとするものである。
【００１４】
【課題を解決するための手段】
本発明の電解水生成装置はその目的を達成するため、原水を電気分解して陰極水と陽極水とを生成する電解槽の上流側に浄水器を設けると共に、原水が浄水器を通過、非通過する原水切換え手段を設けてなる電解水生成装置において、
原水が浄水器を非通過する原水切換え手段の管路を原水切換え手段の浄水器通過管路より径小にしたをことを特徴とすることを要旨とするものである。
【００１５】
【作用】
水道水などの原水を電解槽を通し主に陰極水を吐水する場合には、浄水器を通過させる。他方、主に陽極水を吐水する場合には、原水切換え手段をもって浄水器を非通過させる。この場合、原水は原水切換え手段の径小な管路を流れるため、抵抗を受けて流量が自動的に減少する。殺菌水を得るのに最適な条件にその径を設定しておけば、切換え手段を変えるだけで所望の殺菌、洗浄用陽極水が得られる。
【００１６】
【実施例】
図１は本発明に関わる電解水生成装置の一実施例であり、図２は本発明に関わる切換え手段を説明する図である。図３と同じ作用・機構を示す部材には同じ符号を表示し、重複する説明は省く。以下、本発明を、図面に示した実施例に基づいて説明する。
【００１７】
すなわち、本発明の電解水生成装置は、水道水などの原水を電気分解する電解槽１と、電解槽１の上流側に浄水器１５を備えている。原水の取り入れ側に位置する給水管２３と浄水器の流入口１７との間に切換え手段２１を設けて給水管２３から送られる原水を所望によって浄水器を介してまたは浄水器を介さないで直接電解槽に達する２方向のいずれかに切り換え流通させる。切換え手段２１から分岐された一方の給水管は浄水器を介してその流出口１８から給水管１９に達し、切換え手段２１から分岐された他方の給水管はバイパス給水管２４を介して給水管１９に達する。
【００１８】
切換え手段２１は三方弁のような弁体が使用される。図２（ａ）に示されるように、陰極水を主に得る場合には、原水を給水管２３から取り入れ、浄水器の流入口１７に流入させ、浄水器を通過させた後、電解槽１に供給する。図２（ｂ）に示されるように、陽極水を主に得る場合には、原水を給水管２３から取り入れ、バイパス給水管２４を介して電解槽１に供給する。
【００１９】
切換え手段のバイパス給水管側の管径ｍは浄水器の流入口側に較べて遥かに径小に構成されている。このため、陽極水を得るため切換え手段を図３（ａ）から図３（ｂ）にするとき、原水の流通は上記径小部２２によって制約を受けて流量は少なくなる。すなわち、陰極水を得るため浄水器を通過させるときよりも少なくすることができる。
【００２０】
径小部２２の管径は原水中に含まれる電解質の含有量、電解槽の許容電流容量および所望する陽極水の強度（例えば、ＯＲＰ）などによって適宜変更することができる。
【００２１】
従って、本発明の電解水生成装置では、飲料用の陰極水を主に得ようとする場合には、原水は浄水器を通過するのに対して、洗浄や殺菌用の陽極水を必要とする場合には、切り換え手段２１により原水を浄水器を通過させることなくバイパス給水管２４を通じて電解槽１に供給することができるため、浄水器の不必要な使用を避けることができる。
【００２２】
【発明の効果】
本発明の電解水生成装置において、主に陰極水を吐水する場合には、浄水器を通過させ、他方、主に陽極水を吐水する場合には、原水切換え手段をもって浄水器を非通過させる。この場合、原水は原水切換え手段の径小な管路を流れるため流量は自動的に減少する。殺菌水を得るのに最適な条件にその径を設定しておけば、切換え手段を変えるだけで所望の殺菌、洗浄用陽極水が簡単に得られる。
【００２３】
しかも、陽極水を主に得る際には、切換え手段により原水を浄水器を通過させることなく電解槽に供給するため、浄水器の不必要な使用を避けて寿命を長くすることができる。

[Industrial application fields]
The present invention relates to an electrolyzed water generating apparatus that uses tap water as raw water and performs electrolysis. More specifically, the present invention relates to an electrolyzed water generating device that generates water by switching freely one that mainly discharges cathodic water used for beverages and one that mainly discharges strong anode water used for cleaning water for disinfection or sterilization.
[0002]
[Prior art]
In the electrolyzed water generating apparatus shown in FIG. 3, the electrolyzer 1 is divided into a cathode chamber 11 and an anode chamber 12 by a diaphragm 9, and electrodes 10 and 10 are inserted into their chambers and supplied to the negative anode chamber. The raw water is electrolyzed by energization of a direct current applied between the electrodes, whereby the cathode water is electrolyzed in the cathode chamber and the anode water is electrolyzed in the anode chamber.
[0003]
In a device that mainly discharges cathodic water used for beverages, in order to obtain water quality preferable as drinking water, that is, components that are unsuitable for beverages contained in raw water before supplying the electrolytic cell, such as odors, chalk, and pollutants In order to remove fine impurities such as bacteria and bacteria, a water purifier 15 is attached before inflow of the electrolytic cell, and raw water such as tap water obtained by opening and closing the tap faucet 16 inside and outside the apparatus is supplied to the inlet 17 of the water purifier. At the same time, only the raw water that has flowed out from the outlet 18 and passed through the water purifier 15 is configured to flow into the electrolytic cell 1 through the water supply pipe 19.
[0004]
As described above, the water purifier is composed of the optimal members for the husband to efficiently perform the adsorption action to remove chemical components unsuitable for beverages such as odor and chalk and the filtration action to remove pollutants and bacteria. Yes. That is, the water purifier for this purpose is a granular activated carbon containing silver ions that removes chlorine and the like in tap water and is made into a layer of calcium sulfite and the like as an adsorbent, and further passes a filtration member made of hollow fiber. The way is done. Moreover, the water purifier is configured as a cartridge so that it can be easily replaced when a large amount of raw water passes and the water purifying capacity is reduced, and the water purifier itself is exchanged as the capacity decreases.
[0005]
Conventionally, the cathodic water has been used mainly as drinking water as water having a positive effect on health, while the anodic water has been used as astringent water. The amount of the anodic water used is less than that of the above-mentioned cathodic water, and the anodic water is often drained as it is.
[0006]
However, chlorine and chlorine ions contained in tap water themselves constitute an electrolyte when they are electrolyzed in an electrolytic cell by adding a halogen compound such as NaCl or KCl as an electrolyte to the raw water before supplying the electrolytic cell. The anion moves to the anode chamber. As a result, the anode chamber HClO, ClO ^- lower pH anodic water containing plenty anion is obtained like. Since this water has a disinfection and sterilization effect, it is useful as a cleaning water for disinfection and sterilization.
[0007]
In the electrolyzer for mainly obtaining anodized water containing a large amount of anions having a disinfecting and sterilizing effect, the anodized water is not suitable for beverages, and for the purpose of obtaining anodized water as described above, Is normally drained, it is not necessary to pass raw water to the water purifier at least when discharging the anode water.
[0008]
For this reason, when obtaining cathodic water as drinking water, raw water such as tap water is passed through the water purifier, and when obtaining anode water that is mainly effective for sterilization, the water purifier is bypassed and the raw water is directly electrolyzed. It is conceivable to supply the tank. For example, in the apparatus shown in FIG. 4 disclosed in JP-A-6-154755, the switching means 6 is provided for the water purifier 2 provided on the upstream side of the electrolytic cell 1, and the switching means is operated. Thus, when supplying raw water to the electrolytic cell, the case of passing through the water purifier and the case of not passing through the water purifier can be selected.
[0009]
That is, in the above apparatus, when obtaining cathodic water for beverages, the raw water is passed through the water purifier 2 by the switching means 6 and supplied to the electrolytic cell 1, and anodic water for washing and sterilization is required. In this case, the raw water is directly supplied to the electrolytic cell through the bypass channel 4 without passing the raw water by the switching means 6.
[0010]
The water purifier 2 is filled with activated carbon 7 as a purifying means. A bypass flow path 4 is provided between the water supply pipe 3 and the electrolytic cell 1 located on the upstream side of the water purifier, and a switching means 6 comprising a three-way valve is provided at a branch portion 5 between the water supply pipe 3 and the bypass flow path 4. (A) Supply tap water to an electrolytic cell through a water purifier, or (b) Supply tap water directly to an electrolytic cell without passing the water purifier.
[0011]
In the above apparatus, when drinking cathodic water is required, as shown in FIG. 5 (a), the raw water flows through the three-way valve as the switching means 6 from the water supply pipe 3 to the inlet of the water purifier. Then, after the raw water is once purified by the water purifier 2, the cathode water is generated in the electrolytic cell. Further, when using cleaning or bactericidal anode water, as shown in FIG. 5 (b), the raw water is positioned so as to be supplied from the water supply pipe 3 to the bypass channel 4, and the raw water passes through the purifier 2. Without making it, it supplies to an electrolytic cell directly through the bypass flow path 4, and anodized water is produced | generated with an electrolytic cell. As a result, desired water can be obtained, and when the anode water is obtained, the water purifier is not allowed to pass, so that the life of the water purifier can be extended.
[0012]
[Problems to be solved by the invention]
However, with the above method, if the raw water flows directly from the water supply pipe to the electrolytic cell so that the anode water is not discharged through the water purifier, the flow resistance of the raw water is reduced to the electrolytic cell only through the water purifier. The flow rate of raw water supplied increases.
[0013]
When trying to obtain anode water mainly, especially when using chlorine ions or chlorine contained in the raw water to obtain sterilizing cleaning water that has a disinfection and sterilizing effect, the amount of water supplied is reduced. The desired anode water can be obtained only by performing electrolysis. That is, in the conventional method of simply switching the switching means shown in FIG. 4, the amount of water must be automatically reduced when mainly obtaining the anode water. For this reason, it is necessary to provide a means for controlling the amount of water on the supply side or the discharge side of the raw water, or a means for automatically increasing the current applied to the negative anode of the electrolytic cell in accordance with the amount of supplied water.
Therefore, in the present invention, when the anode water is mainly obtained, the amount of water supplied to the electrolytic cell is automatically reduced to easily obtain the sterilizing cleaning water that can extend the life of the water purifier while solving the above problems. The device is to be provided.
[0014]
[Means for Solving the Problems]
In order to achieve the object, the electrolyzed water generating device of the present invention is provided with a water purifier upstream of the electrolyzer that electrolyzes raw water to generate cathodic water and anodized water, and the raw water passes through the water purifier, In the electrolyzed water generating device provided with the raw water switching means to pass through,
The gist is characterized in that the diameter of the pipe of the raw water switching means through which the raw water does not pass through the water purifier is made smaller than that of the water purifier passing pipe of the raw water switching means.
[0015]
[Action]
When raw water such as tap water passes through the electrolytic cell and mainly discharges the cathode water, the water is passed through the water purifier. On the other hand, when mainly discharging the anode water, the water purifier is made to pass through the raw water switching means. In this case, since the raw water flows through a small diameter pipe of the raw water switching means, the flow rate is automatically reduced due to resistance. If the diameter is set to an optimum condition for obtaining the sterilizing water, the desired sterilizing / cleaning anode water can be obtained simply by changing the switching means.
[0016]
【Example】
FIG. 1 is an embodiment of an electrolyzed water generating apparatus according to the present invention, and FIG. 2 is a diagram for explaining switching means according to the present invention. Members having the same action / mechanism as in FIG. 3 are denoted by the same reference numerals, and redundant description is omitted. Hereinafter, the present invention will be described based on the embodiments shown in the drawings.
[0017]
That is, the electrolyzed water generating apparatus of the present invention includes an electrolyzer 1 that electrolyzes raw water such as tap water, and a water purifier 15 on the upstream side of the electrolyzer 1. A switching means 21 is provided between the water supply pipe 23 located on the raw water intake side and the inlet 17 of the water purifier, and the raw water sent from the water supply pipe 23 is directly passed through the water purifier or not through the water purifier as required. Switch to one of two directions to reach the electrolytic cell. One water supply pipe branched from the switching means 21 reaches the water supply pipe 19 from the outlet 18 via the water purifier, and the other water supply pipe branched from the switching means 21 is supplied to the water supply pipe 19 via the bypass water supply pipe 24. To reach.
[0018]
The switching means 21 is a valve body such as a three-way valve. As shown in FIG. 2 (a), when the cathode water is mainly obtained, the raw water is taken from the water supply pipe 23, flows into the inlet 17 of the water purifier, passes through the water purifier, and then the electrolytic cell 1 To supply. As shown in FIG. 2B, when mainly obtaining anode water, raw water is taken from the water supply pipe 23 and supplied to the electrolytic cell 1 through the bypass water supply pipe 24.
[0019]
The pipe diameter m on the bypass water supply pipe side of the switching means is configured to be much smaller than the inlet diameter of the water purifier. Therefore, when the switching means is changed from FIG. 3A to FIG. 3B in order to obtain anode water, the flow of raw water is restricted by the small diameter portion 22 and the flow rate is reduced. That is, it can be reduced compared with the case where it passes through a water purifier in order to obtain cathode water.
[0020]
The tube diameter of the small diameter portion 22 can be appropriately changed depending on the content of the electrolyte contained in the raw water, the allowable current capacity of the electrolytic cell, the desired strength of anodic water (for example, ORP), and the like.
[0021]
Therefore, in the electrolyzed water generating apparatus of the present invention, when the cathodic water for drinking is mainly obtained, the raw water passes through the water purifier, whereas the anodic water for cleaning and sterilization is required. In this case, since the raw water can be supplied to the electrolytic cell 1 through the bypass water supply pipe 24 without passing through the water purifier by the switching means 21, unnecessary use of the water purifier can be avoided.
[0022]
【The invention's effect】
In the electrolyzed water generating apparatus of the present invention, when mainly discharging the cathode water, the water purifier is allowed to pass through. On the other hand, when mainly discharging the anode water, the water purifier is made non-passable by the raw water switching means. In this case, since the raw water flows through the small diameter pipe of the raw water switching means, the flow rate automatically decreases. If the diameter is set to an optimum condition for obtaining sterilizing water, the desired sterilizing and washing anode water can be easily obtained by simply changing the switching means.
[0023]
In addition, when the anode water is mainly obtained, since the raw water is supplied to the electrolytic cell by the switching means without passing through the water purifier, the life can be extended by avoiding unnecessary use of the water purifier.
