Description

本発明は、貯水槽の注水部構造に関するものである。   The present invention relates to a water injection part structure of a water storage tank.

従来、食塩水を用いて真水をアルカリ水と酸性水との電解水に分解し、それぞれの電解水をアルカリ水タンクと酸性水タンクに貯留し、貯留された電解水を利用し衣類等の洗濯を洗剤を使用することなく行うことを可能とする電解装置は、特許文献１に示されるように既に公知である。この電解装置の電解水を貯留する貯水槽（タンク）は、その上方位置に開口される電解水の導入口に、電解槽から電解水を導入して流入させる導入管を設けた注水部構造を採用している。   Conventionally, fresh water is decomposed into electrolyzed water of alkaline water and acidic water using a saline solution, and each electrolyzed water is stored in an alkaline water tank and an acidic water tank, and laundry is washed using the stored electrolyzed water. As shown in Patent Document 1, an electrolysis apparatus that can perform the process without using a detergent is already known. The water storage tank (tank) for storing the electrolyzed water of this electrolyzer has a water injection part structure in which an introduction pipe for introducing and flowing in electrolyzed water from the electrolyzer is introduced into an electrolyzed water inlet opening above the electrolyzed water. Adopted.

この注水部構造において、導入管を導入口からタンク底壁まで延長したパイプの下端のみから電解水を流出させる構成にすると、満水状態にするためにはパイプ内の水圧に抗して電解水を高圧で供給する必要があることから、一般的には導入口位置に臨む導入管の開口部から電解水を放出し自由落下させて貯留する構造とされる。
特開２００４−８９８３公報 In this water injection part structure, if the introduction water is made to flow out only from the lower end of the pipe extending from the introduction port to the tank bottom wall, the electrolysis water is resisted against the water pressure in the pipe in order to fill the water. Since it is necessary to supply at a high pressure, the electrolytic water is generally discharged from the opening of the introduction pipe facing the introduction port position, and is free-falled and stored.
JP 2004-8983 A

上記特許文献１で示される注水部構造は、貯水槽の上方位置に設けた導入管の開口部から電解水を自由落下させて貯留するので、導入管から放出される電解水は、液滴となって内部の空気抵抗を受けて拡散状態でエアーと接触しながら落下する。また電解水は大きな落差を有して落下するので、貯水槽の内部底面（底壁）や水面に衝突し水飛沫を伴って貯留される。   The water injection part structure shown in the above-mentioned Patent Document 1 stores electrolytic water by freely dropping electrolyzed water from the opening of the introduction pipe provided at the upper position of the water storage tank. It falls in contact with air in a diffused state due to internal air resistance. Moreover, since electrolyzed water falls with a big drop, it collides with the internal bottom face (bottom wall) and water surface of a water storage tank, and is stored with water droplets.

このように電解水を貯留するとき、水飛沫や液滴がタンク内エアーと接触する従来方式の注水部構造は、電解槽によって生成された電解水のＯＲＰ（酸化還元電位）の値を大きく変動させることが指摘された。特にアルカリ水はＯＲＰの値を大きく増加させる。   Thus, when storing electrolyzed water, the conventional water injection part structure in which water droplets or droplets come into contact with the air in the tank greatly fluctuates the ORP (oxidation-reduction potential) value of the electrolyzed water generated by the electrolyzer. It was pointed out that In particular, alkaline water greatly increases the value of ORP.

図６はアルカリ電解水の落下試験を行い酸化還元電位の変動を確認したグラフで、この試験では電解槽で生成された電解水のＯＲＰが−８５０ｍＶ程度のアルカリ水を、高さ１２００ミリ程度の貯水槽に、内径９ミリ程度の導入管の開口端から、５０ミリの落差間隔毎に自然落下させ、その着水地点近傍の貯留アルカリ水をＯＲＰ計測器によって計測した。 FIG. 6 is a graph in which a drop test of alkaline electrolyzed water was performed to confirm the change in oxidation-reduction potential. In this test, alkaline water having an ORP of about -850 mV of electrolyzed water generated in the electrolytic cell was measured with a height of about 1200 mm. The water storage tank was naturally dropped from the opening end of the introduction pipe having an inner diameter of about 9 mm at every head interval of 50 mm, and the stored alkaline water in the vicinity of the landing point was measured with an ORP measuring instrument.

これによれば導入管から流出落下するアルカリ水は、底壁から導入管の開口端の高さが略３００ミリの範囲では、水飛沫を大きく生ずることなく緩やかに着水し、ＯＲＰは−１５ｍＶ程度の範囲で変動し−８００ｍＶ以下の値を維持することが確認された。
このレベルのアルカリ水を洗濯水として利用実験したところ、有効利用が可能な酸化還元電位の変動許容範囲を維持することが判明した。 According to this, the alkaline water flowing out from the introduction pipe is landed gently without causing large water splash in the range where the height of the opening end of the introduction pipe from the bottom wall is about 300 mm, and the ORP is −15 mV. It was confirmed that the value fluctuated within a range and maintained at a value of −800 mV or less.
When this level of alkaline water was used as washing water, it was found that the allowable range of oxidation-reduction potential fluctuations that can be used effectively was maintained.

またアルカリ水の落差が３００ミリでは−８２４ｍＶ程度であり、ここを越え落差４５０ミリ程度で落下するとき、着水時の水飛沫も大きくなってアルカリ水のＯＲＰは、−６５ｍＶ程度と一挙に変動増加し、その後はＯＲＰの値は落差１２００ミリ程度で維持され大きく変動しないことも確認された。   In addition, when the drop of alkaline water is 300 mm, it is about -824 mV, and when falling over about 450 mm, the splash of water upon landing increases, and the ORP of alkaline water fluctuates at around -65 mV. After that, it was confirmed that the value of ORP was maintained at a drop of about 1200 mm and did not fluctuate greatly.

そこで本発明は、電解処理された電解水並びに還元水や一般に名水と言われるミネラル水等の、所定の酸化還元電位を有し当該酸化還元電位を保持すべき水を、水飛沫の発生を抑制し酸化還元電位の大きな変動を防止して、貯水槽内に供給することができる貯水槽の注水部構造を提供することを目的とする。   Therefore, the present invention suppresses the generation of water droplets with water that has a predetermined oxidation-reduction potential, such as electrolyzed electrolyzed water, reduced water, or mineral water, which is generally called famous water, and that should retain the oxidation-reduction potential. It is an object of the present invention to provide a water injection part structure of a water storage tank that can prevent large fluctuations in the oxidation-reduction potential and can be supplied into the water storage tank.

上記課題を解決するための貯水槽の注水部構造は、第１に、所定の酸化還元電位を有し、当該酸化還元電位を保持すべき水を導入して貯留する貯水槽７の上方位置に水の導入口２１を設け、該導入口２１より流入する水を貯水槽７内に案内する案内部材２２を下向きに設けたものにおいて、上記案内部材２２として内部に水を流通させるパイプを用い、該パイプの周壁に上下方向の所定のピッチ毎にパイプ内の水をパイプ外に流出させてパイプ外周面に沿って流下させるように案内する案内孔２３を開設してなることを特徴としている。 The water injection part structure of the water tank for solving the above-mentioned problem is, firstly, at a position above the water tank 7 which has a predetermined oxidation-reduction potential and introduces and stores water to hold the oxidation-reduction potential. In the case where a water introduction port 21 is provided, and a guide member 22 that guides the water flowing from the introduction port 21 into the water storage tank 7 is provided downward, a pipe through which water flows is used as the guide member 22. is characterized by comprising opened guide hole 23 for guiding so that flowed down the water in the pipes at predetermined pitches in the vertical direction in a peripheral wall of the pipe along the pipe outer peripheral surface by flow out pipe .

第２に、案内部材２２の下端の貯水槽７の内部底面からの高さ（落差）を水の落下による酸化還元電位の変動を許容範囲内に収める許容高さ以下にするとともに、該案内部２２を電解水が液滴となって落下しない程度に下向きに傾斜させたことを特徴としている。 Second, the height (head) of the lower end of the guide member 22 from the inner bottom surface of the water storage tank 7 is set to be less than or equal to an allowable height that can accommodate the fluctuation of the oxidation-reduction potential due to the drop of water within the allowable range. 22 is inclined downward so that the electrolyzed water does not fall as droplets .

第３に、案内孔２３の開口面積を案内部材２２のパイプ内径断面以上に設定したことを特徴としている。   Third, the opening area of the guide hole 23 is set to be equal to or larger than the pipe inner diameter section of the guide member 22.

第４に、案内孔２３のパイプ内面からの切り込み深さを、パイプの内径の半径に達する深さとしたことを特徴としている。   Fourthly, the depth of cut from the inner surface of the guide hole 23 is a depth that reaches the radius of the inner diameter of the pipe.

第５に、案内部材２２を水との接触により水の酸化還元電位に影響を与えないプラスチック材又はセラミック材としたことを特徴としている。 Fifth , the guide member 22 is characterized in that it is made of a plastic material or a ceramic material that does not affect the redox potential of water by contact with water.

上記のように構成される本発明の貯水槽の注水部構造は、所定の酸化還元電位を有した水を、パイプの周壁に上下方向の所定のピッチ毎に水をパイプ外に流出させるように案内する案内孔を開設した案内部材によって貯水槽に貯水することにより、案内孔から流出する水は案内部材の表面を伝わり水飛沫を発生させることなく緩やかに着水し、酸化還元電位の大きな変動を防止して貯水槽に供給することができる。   The water injection portion structure of the water storage tank of the present invention configured as described above causes water having a predetermined oxidation-reduction potential to flow out of the pipe at predetermined pitches in the vertical direction on the peripheral wall of the pipe. By storing water in the water storage tank with a guide member that has a guide hole that guides it, the water flowing out of the guide hole is gently transferred to the surface of the guide member without generating water droplets, and the oxidation-reduction potential varies greatly. Can be prevented and supplied to the water tank.

このとき案内部材の下端の貯水槽の内部底面からの高さは、水の落下による酸化還元電位の上昇変動を許容範囲内に収める許容高さ（約３００ｍｍ）以下にしたことにより、案内部材の下端から水を流出するとき大きな水飛沫の発生を防止し貯水槽内に供給することができる。   At this time, the height of the lower end of the guide member from the inner bottom surface of the water storage tank is set to be less than an allowable height (about 300 mm) within which an increase in oxidation-reduction potential due to water drop falls within an allowable range. When water flows out from the lower end, it is possible to prevent generation of large water droplets and supply the water into the water storage tank.

また案内孔の開口面積は案内部材のパイプ内径断面以上に設定することにより、案内孔から流出する水を液滴にすることなく、案内部材の表面に沿わせて速やかに流下させることができる。また案内孔は切り込み深さをパイプの内径の半径に達する深さとすることにより、大きな案内孔の開口面積を形成しながらパイプ剛性を維持することができる。   In addition, by setting the opening area of the guide hole to be equal to or larger than the pipe inner diameter cross section of the guide member, the water flowing out from the guide hole can be quickly flowed down along the surface of the guide member without forming droplets. In addition, the guide hole can maintain the rigidity of the pipe while forming a large opening area of the guide hole by setting the cutting depth to a depth that reaches the radius of the inner diameter of the pipe.

また案内部材は水との接触により水の酸化還元電位に影響を与えないプラスチック材又はセラミック材としたことにより、水を案内部材を伝わらせて流下する際に、酸化還元電位の変動を防止して貯水槽に供給することができる。   In addition, the guide member is made of a plastic material or ceramic material that does not affect the redox potential of water by contact with water, thereby preventing fluctuations in the redox potential when water flows down the guide member. Can be supplied to the water tank.

本発明の一実施形態を図面に基づいて説明する。図１は本発明による貯水槽の注水部構造を備えた電解装置１の全体構造を示し、図２は電解装置１の各部の配置及び配管図である。電解装置１は箱型のボックス２内に、水道管に接続され吸水管３から供給される真水（水道水）を電解し酸性水とアルカリ水とに分解する電解槽５と、該電解槽５の陽極側から送り出される酸性水を収容する貯水槽（以下酸性水タンクと言う）６と、陰極側から送り出されるアルカリ水を収容する貯水槽（以下アルカリ水タンクと言う）７等が収納設置される。   An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the overall structure of an electrolysis apparatus 1 having a water injection part structure of a water storage tank according to the present invention, and FIG. 2 is an arrangement and piping diagram of each part of the electrolysis apparatus 1. The electrolyzer 1 is provided in a box-shaped box 2, an electrolytic cell 5 for electrolyzing fresh water (tap water) connected to a water pipe and supplied from a water absorption pipe 3 to decompose it into acidic water and alkaline water, and the electrolytic tank 5. A storage tank (hereinafter referred to as an acidic water tank) 6 for storing acidic water sent out from the anode side of the water tank, a water storage tank (hereinafter referred to as an alkaline water tank) 7 for storing alkaline water sent out from the cathode side, etc. are housed and installed. The

上記電解槽５は、電解質である塩水が自然流出される排水をポンプ９を介して収容する電解質供給タンク１０と、該電解質供給タンク１０に電解質を供給する電解質貯留タンク１１を備えている。また電解質供給タンク１０内には塩分濃度が低く酸性度が高くなった酸性電解水も収容される。電解槽５は一定の直流電流を供給する直流電源１２によって作動される。   The electrolytic tank 5 includes an electrolyte supply tank 10 that stores drainage from which salt water as an electrolyte naturally flows out via a pump 9, and an electrolyte storage tank 11 that supplies the electrolyte to the electrolyte supply tank 10. The electrolyte supply tank 10 also stores acidic electrolyzed water having a low salinity concentration and a high acidity. The electrolytic cell 5 is operated by a DC power source 12 that supplies a constant DC current.

この実施形態による電解槽５によって水道水を電解処理したとき得られるアルカリ水は、ＯＲＰの値が−８５０ｍＶ程度であり、且つｐＨは１１．５０程度である。また酸性水はＯＲＰの値が１１００ｍＶ程度であり、且つｐＨは２．９程度の電解水が生成される。
それぞれの電解水は導入管８，８を介し、酸性水タンク６とアルカリ水タンク７に対し自然流出方式によって供給される。 The alkaline water obtained when the tap water is electrolyzed by the electrolytic cell 5 according to this embodiment has an ORP value of about -850 mV and a pH of about 11.50. Acidic water produces electrolyzed water having an ORP value of about 1100 mV and a pH of about 2.9.
The respective electrolyzed water is supplied to the acidic water tank 6 and the alkaline water tank 7 through the introduction pipes 8 and 8 by a natural outflow method.

以上のように構成される電解装置１は、酸性水タンク６に貯留される酸性水と、アルカリ水タンク７に貯留されるアルカリ水とを、取出バルブ１５，１６を備えた電解水取出管１７，１９からそれぞれ必要量を取り出すことができる。この電解水取出管１７，１９は取出管２０に合流され、酸性水又はアルカリ水が各別に又は必要量を混合した状態で取り出すことができる。上記タンク６，７の上部にはいずれにもエア抜き（図示しない）が設けられている。   The electrolyzer 1 configured as described above is configured to extract the acidic water stored in the acidic water tank 6 and the alkaline water stored in the alkaline water tank 7 from the electrolytic water extraction pipe 17 having extraction valves 15 and 16. , 19 can be taken out the required amount. The electrolyzed water take-out pipes 17 and 19 are joined to the take-out pipe 20 and can be taken out separately in a state where acidic water or alkaline water is mixed separately or in a necessary amount. Air vents (not shown) are provided in the upper portions of the tanks 6 and 7.

尚、各タンクにはそれぞれの液面を検出する液面センサが付設されている。また各タンクの水量や電解水生成量の調節に際し、それぞれのタンクのセンサー検出値等に応じ、図示しないそれぞれのバルブ類を制御して給排水の過不足を補うことができる。この制御を自動的に行うには、各センサーによる検出信号を入力し、バルブ制御信号等に変換して出力制御する制御装置が必要なことは言うまでもない。   Each tank is provided with a liquid level sensor for detecting the liquid level. In addition, when adjusting the amount of water in each tank or the amount of electrolyzed water generated, it is possible to compensate for excess or deficiency of water supply and drainage by controlling each valve (not shown) according to the sensor detection value of each tank. In order to perform this control automatically, it goes without saying that a control device that inputs detection signals from each sensor, converts them into valve control signals and the like and controls output is necessary.

次にアルカリ水タンク７の注水部構造について説明する。アルカリ電解水を導入して貯留するアルカリ水タンク７は、タンクの上方位置に電解水の導入口２１を設け、該導入口２１側から流入する電解水をタンク内の底部に向けて案内する案内部材２２を下向きに延長させて設けている。   Next, the water injection part structure of the alkaline water tank 7 will be described. The alkaline water tank 7 for introducing and storing alkaline electrolyzed water is provided with an electrolyzed water inlet 21 at an upper position of the tank, and guides the electrolyzed water flowing from the inlet 21 toward the bottom of the tank. The member 22 is provided so as to extend downward.

図２〜図５で示すように案内部材２２は、電解水を内部に流通させるパイプの外周壁に、電解水をパイプ外に流出させるように案内する複数の案内孔２３を、タンク内部高さにわたって上下方向の所定のピッチ毎に開設している。また案内部材２２はパイプ上端部を前記導入管８にジョイント部を介し着脱可能に連結した状態で、中途部の上方を導入口２１を塞ぐ止め蓋２４に挿入し支持している。   As shown in FIGS. 2 to 5, the guide member 22 has a plurality of guide holes 23 for guiding the electrolytic water to flow out of the pipe on the outer peripheral wall of the pipe through which the electrolytic water flows. It is opened every predetermined pitch in the vertical direction. The guide member 22 is inserted into and supported by a stopper lid 24 that closes the introduction port 21 above the midway part in a state where the upper end of the pipe is detachably connected to the introduction pipe 8 via a joint.

案内部材２２をアルカリ水タンク７内に略垂直状に設置するとき、上下方向に隣接する案内孔２３のピッチ間隔と、案内部材２２の最下部に形成される案内孔２３或いはパイプ下端の開口とアルカリ水タンク７の内部底面からの高さ（落差）は、共に電解水を放出する際に、酸化還元電位の変動を許容値内に収めることができる許容高さ以下に設定している。   When the guide member 22 is installed in the alkaline water tank 7 in a substantially vertical shape, the pitch interval between the guide holes 23 adjacent in the vertical direction and the guide hole 23 formed at the lowermost portion of the guide member 22 or the opening at the lower end of the pipe The height (drop) from the inner bottom surface of the alkaline water tank 7 is set to be equal to or less than an allowable height at which the fluctuation of the oxidation-reduction potential can be kept within an allowable value when the electrolyzed water is discharged.

さらに案内孔２３の開口面積は、案内部材２２のパイプ内径断面以上に設定して開口させている。これによりパイプ内を流れる電解水は、各案内孔２３から流出するとき、絞り抵抗によって外側に液滴状になって放出落下されることなく、パイプ内から溢れ出る状態で外周面を伝わって下方に流出案内される。これによりパイプ外周面に沿って流下する電解水は、アルカリ水タンク７内で底壁や貯留された電解水の水面に、大きな水飛沫を発生させることなく着水することができる。   Further, the opening area of the guide hole 23 is set to be larger than the pipe inner diameter cross section of the guide member 22 and is opened. As a result, when the electrolyzed water flowing in the pipe flows out from each guide hole 23, the electrolyzed water flows down the outer peripheral surface in a state of overflowing from the pipe without being discharged and dropped in the form of droplets by the squeezing resistance. It is guided to outflow. As a result, the electrolyzed water flowing down along the outer peripheral surface of the pipe can land on the bottom wall or the surface of the electrolyzed water stored in the alkaline water tank 7 without generating large water droplets.

案内孔２３はその切り込み深さを、パイプ表面から内径の半径（略中心）に達する深さ迄とし長孔状に形成している。これにより案内部材２２は長いパイプの強度を維持し、且つ案内孔２３の流出開口を広く形成して電解水の流出を緩やかにすることができる。
また案内部材２２は、ポリプロピレン，塩化ビニール等のプラスチック材又はセラミック材からなる非金属製のパイプで形成され、電解水を貯留する際に酸化還元電位の上昇変動を防止することができる。 The guide hole 23 is formed in the shape of a long hole so that the cut depth is from the pipe surface to the depth reaching the radius (substantially center) of the inner diameter. As a result, the guide member 22 can maintain the strength of the long pipe, and can widen the outflow opening of the guide hole 23 to make the outflow of the electrolytic water gentle.
Moreover, the guide member 22 is formed of a non-metallic pipe made of a plastic material such as polypropylene or vinyl chloride or a ceramic material, and can prevent an increase in oxidation-reduction potential when storing electrolyzed water.

以上のように構成される注水部構造は、図３，図４で示すようにアルカリ水タンク７の止め蓋２４に支持された案内部材２２のパイプ下端から、又はパイプ下端が閉じられた構成の場合は直上の案内孔２３から、電解水をタンク内に供給し水位を上昇させる。
そして、アルカリ水タンク７内に順次貯留される電解水は、水位を上昇させ同図の線Ａ位置に至るとき、前記第１の案内孔２３を完全に塞ぐことになる。 As shown in FIGS. 3 and 4, the water injection portion structure configured as described above has a configuration in which the pipe lower end of the guide member 22 supported by the stopper cover 24 of the alkaline water tank 7 is closed or the pipe lower end is closed. In this case, electrolytic water is supplied into the tank from the guide hole 23 directly above to raise the water level.
And the electrolyzed water sequentially stored in the alkaline water tank 7 will completely block the first guide hole 23 when the water level rises and reaches the position of line A in FIG.

次いで同図の線Ａで示す水位においてパイプ内の電解水は第２の案内孔２３に至り流出し、アルカリ水タンク７内の水位を再び上昇させ第２の案内孔２３を塞ぐ。以下同様に第３，第４・・の案内孔２３から電解水の流出が繰り返され、タンク内の水位が上昇する。   Next, at the water level indicated by the line A in the figure, the electrolyzed water in the pipe reaches the second guide hole 23 and flows out, and the water level in the alkaline water tank 7 is raised again to close the second guide hole 23. Similarly, the outflow of electrolyzed water from the third, fourth,... Guide holes 23 is repeated, and the water level in the tank rises.

このときアルカリ水タンク７内に供給される電解水の落下供給高さは、電解水の落下による酸化還元電位の変動を許容値内に収めることができる許容距離（高さ）以下に設定しているので、案内孔２３から流出する電解水は案内部材２２の表面を伝わって、貯留された電解水の水面に水飛沫を発生させることなく緩やかに着水することができる。   At this time, the drop supply height of the electrolyzed water supplied into the alkaline water tank 7 is set to be equal to or less than an allowable distance (height) that can keep the fluctuation of the oxidation-reduction potential due to the drop of the electrolyzed water within an allowable value. Therefore, the electrolyzed water flowing out from the guide hole 23 is transmitted along the surface of the guide member 22, and can be landed gently without generating water splashes on the surface of the stored electrolyzed water.

これにより電解槽５によって生成された電解水は、落下による酸化を伴うことなく、酸化還元電位の上昇変動を抑制することができる。従って、アルカリ水をアルカリ水タンク７に供給する際に、酸化還元電位を許容値内に維持して貯留することができ、またアルカリ水を洗濯水として利用するときも所期の洗濯効果を発揮することができる。   Thereby, the electrolyzed water produced | generated by the electrolytic vessel 5 can suppress the raise fluctuation | variation of an oxidation-reduction potential, without being accompanied by the oxidation by fall. Therefore, when supplying alkaline water to the alkaline water tank 7, the oxidation-reduction potential can be maintained and stored within an allowable value, and the desired washing effect is exhibited even when alkaline water is used as washing water. can do.

この実施形態における案内部材２２は、タンク高さと略同じ１２００ミリ程度とし、外径が１２ミリ，内径が９ミリ程度の非金属製のパイプとし、案内孔２３のピッチは１５０ミリ程度にした。そしてＯＲＰの値が−８５０ｍＶ程度のアルカリ水の供給時の落差は、図６において既述した落下許容高さの３００ミリ程度に対し、案内孔２３のピッチと同じ１５０ミリ程度以下にしたことにより、ＯＲＰを殆ど変動させることなくアルカリ水タンク７から取出管２０を介し取り出すことができた。 The guide member 22 in this embodiment is about 1200 mm, which is substantially the same as the tank height, is a non-metallic pipe having an outer diameter of 12 mm and an inner diameter of about 9 mm, and the pitch of the guide holes 23 is about 150 mm. The drop when supplying alkaline water with an ORP value of about -850 mV is about 150 mm or less, which is the same as the pitch of the guide holes 23, with respect to the drop allowable height of about 300 mm described in FIG. The ORP could be taken out from the alkaline water tank 7 through the take-out pipe 20 with almost no change.

尚、図示例の案内部材２２は垂直状に立設させたが、電解水が液滴となって落下しない程度に傾斜させることもできる。この場合には案内部材２２に穿設する複数の案内孔２３は傾斜するパイプ表面に一列状に上向きに形成することが望ましい。また電解水は電解槽５から給水ポンプを用いることにより、酸性水タンク６とアルカリ水タンク７に供給することもできる。   In addition, although the guide member 22 in the illustrated example is set up vertically, the guide member 22 may be inclined so that the electrolyzed water does not fall as a droplet. In this case, it is desirable to form the plurality of guide holes 23 formed in the guide member 22 upward in a line on the inclined pipe surface. Electrolyzed water can also be supplied from the electrolytic cell 5 to the acidic water tank 6 and the alkaline water tank 7 by using a water supply pump.

上記電解装置１は、図１で示すように水道水や地下水等の硬水を軟水化させる軟水器３０を切換バルブを介して吸水管３側に設け、軟水処理された軟水を取出管２０から取り出し可能に設けることもできる。この場合にはアルカリ水と酸性水に加え軟水を電動ボールバルブやエアーバルブのコントロールによって、図示しない洗濯機の供給口内に切り換え供給することにより、次のような洗濯を行うことができる。   As shown in FIG. 1, the electrolyzer 1 is provided with a water softener 30 for softening hard water such as tap water or ground water on the side of the water absorption pipe 3 through a switching valve, and takes out the soft water subjected to the soft water treatment from the discharge pipe 20. It can also be provided. In this case, the following washing can be performed by supplying soft water in addition to alkaline water and acidic water to a supply port of a washing machine (not shown) by controlling an electric ball valve or an air valve.

即ち、この洗濯手段を備える電解装置１は、例えば工程サイクルが２０分程度に設定された洗濯を行うとき、先ずアルカリ水のみによる洗濯を５分程度行って、被洗濯物の汚れ落としを主体とするアルカリ水洗濯をする。次いで洗濯機の排水弁を開放しアルカリ水を排出したのち、軟水を供給しアルカリ成分を除去する軟水洗濯を３分程度行い排水弁の開放により軟水を排出する。   That is, the electrolysis apparatus 1 equipped with this washing means, for example, when performing washing with a process cycle set to about 20 minutes, first performs washing only with alkaline water for about 5 minutes, and mainly removes dirt from the laundry. Wash with alkaline water. Next, the drain valve of the washing machine is opened and the alkaline water is discharged. Then, soft water washing is performed for about 3 minutes to supply the soft water and remove the alkaline components, and the soft water is discharged by opening the drain valve.

次いで酸性水を供給し殺菌、脱臭、漂白を主体とする酸性水洗濯を５分程度行う。こののち排水弁を開放し酸性水を排出し被洗濯物の洗濯を完了する。この洗濯工程において酸性水洗濯の際に、軟水を２０％程度混入することにより洗濯水をｐＨ３程度に調整すると、色物の被洗濯物の色落ちを防ぐことができる。
上記洗濯手段によれば、洗剤等を使用することなく多様な被洗濯物に対し、汚れ落とし，殺菌，漂白，脱臭等を効果的に行うことができる。またすすぎ洗濯も簡単であり洗濯水の節約を図ることができると共に、残留物の影響を無くし洗濯物の柔軟仕上げを行うことができる等の特徴がある。 Next, acid water is supplied and acid water washing mainly for sterilization, deodorization and bleaching is performed for about 5 minutes. After that, the drain valve is opened to discharge the acidic water and the washing of the laundry is completed. When washing water is adjusted to about pH 3 by mixing about 20% of soft water during acid washing in this washing step, discoloration of the colored laundry can be prevented.
According to the above-described washing means, it is possible to effectively remove stains, sterilize, bleach, deodorize, and the like on various laundry items without using a detergent or the like. In addition, rinsing and washing are easy, and it is possible to save the washing water, and there is a feature that the influence of the residue is eliminated and the laundry can be softly finished.

また上記注水部構造は酸性水タンク６にも使用することができるが、酸性電解水では落下によるＯＲＰ変動が少ないので使用の意味は乏しい。   Moreover, although the said water injection part structure can be used also for the acidic water tank 6, since there is little ORP fluctuation | variation by fall in acidic electrolyzed water, the meaning of use is scarce.

以上のように構成される注水部構造は、電解槽５によって生成されるアルカリ水をアルカリ水タンク７に供給する場合の他、一般的に自然の名水と称される酸化還元電位の低いミネラル水を、水源から貯水槽としてのポリタンクやペットボトル等に供給する際にも、酸化還元電位の変動を抑制し効果的に利用することができる。この場合には貯水槽の導入口に適宜な止め蓋等を介し着脱可能に構成した案内部材２２を、導入パイプ又は漏斗を介して水源と接続することにより簡単に給水することができる。   The water injection part structure configured as described above is a mineral water having a low oxidation-reduction potential generally referred to as natural water, in addition to supplying alkaline water generated by the electrolytic cell 5 to the alkaline water tank 7. When supplying water from a water source to a plastic tank, a plastic bottle or the like as a water storage tank, fluctuations in the oxidation-reduction potential can be suppressed and effectively used. In this case, it is possible to supply water easily by connecting the guide member 22 configured to be detachable from the inlet of the water storage tank through an appropriate stopper lid or the like to the water source through the introduction pipe or the funnel.
