Incidentally, the configurations and operating principles of the electrolytic tank and the salt water (electrolyte) tank of the electrolyzed water generating device of FIG. 1 are the same as those in Patent Document 1 and Non-Patent Document 1.

  This apparatus includes a three-chamber type electrolytic cell 1 and a salt water tank 2 that stores and circulates a salt water as an electrolyte (liquid) in the electrolytic cell 1 for circulation. The electrolytic cell 1 is a vertically long plate-shaped rectangular parallelepiped ( A vertically long intermediate chamber (electrolyte chamber) 4 partitioned by left and right ion-permeable diaphragms (anion exchange membrane 3a, cation exchange membrane 3b) is formed at the center. Further, an anode chamber 6 and a cathode chamber 7 are formed on both the left and right sides. Sheet-like positive and negative electrodes 8a and 8b having water permeability are provided along the outer sides of the respective diaphragms 3.

  The upper and lower sides of the salt water tank 2 and the intermediate chamber 4 are connected by circulation paths (piping) 9 a and 9 b for circulating salt water (electrolyte), and the supply side circulation path 9 a connecting the lower part of the salt water tank 2 and the upper part of the intermediate chamber 4.

In addition, a drain pipe 14 with a drain valve 13 is provided at the lower part of the salt water tank 2 to discharge the salt water when the salt water in the salt water tank 2 is repeatedly used and the electrolytic function is reduced. . Reference numeral 16 denotes a level sensor that detects the level of the salt solution provided in the salt water tank 2.

  Further, branch pipes 17a and 17b branched from a water supply pipe 17 for supplying tap water are connected to the lower part of the anode chamber 6 and the cathode chamber 7, respectively. Extraction pipes 18a and 18b for taking out water (highly reduced water in which positive ions are dissolved and high oxidized water in which negative ions are dissolved) are connected to each other, and the front ends of the respective extraction pipes 18a and 18b also serve as an ejection nozzle or an ejection nozzle. A spout (not shown) is provided.

Each is provided. Moreover, you may provide the heating apparatus (not shown) for warming extraction water (for example, to 35 degreeC) to either the water supply circuit 17 side or extraction pipe 18a, 18b.

  Next, a description will be given of an electric system for performing electrolysis operation and supply / drainage, electrolyzed water extraction and other controls in the electrolyzer 1. The electrolysis circuit uses a 100V AC power source and is connected to the electrolysis electrodes 8a and 8b. 24 and a control circuit 26 used for various operation controls.

  Since the electrolytic circuit 24 applies DC power to the electrodes 8a and 8b, the ends thereof are connected to the positive electrode 8a and the negative electrode 8b, but the main switch 27, the converter (electrolytic power source) 28, and electrode switching are connected from the base end side. The changeover switch 29 is interposed. In addition to AC-DC conversion, the converter 28 has a function of, for example, transforming a DC output voltage to 12 V and outputting it at a constant current of 6A. The output at a constant current here is for changing the voltage according to the electrolytic load. The changeover switch 29 is provided to separate and remove the scale adhering to each electrode by the continuation of the electrolytic operation.

  On the other hand, on the control circuit 26 side, for example, a converter 31 for control power source that outputs 30 W at 24 VDC is provided, and on the output side, the pump 11, the water supply electromagnetic valve 22, and other devices and switches are used as input signals. A control device 32 provided with a program for controlling accordingly is provided.

Various electrical components and the like required for the operation are installed as necessary.

  Further, the structure, function and usage of the electrolytic cell 1 of the apparatus shown in FIG. 1 are basically the same as those shown in Patent Document 1, but this is used for hand washing and disinfection as described later.

The electrolytic bath provided on both sides of the intermediate chamber 4 by circulating the electrolytic solution between the intermediate chamber 4 of 1 and a salt water tank 2 containing a saline solution as an electrolytic solution. The point that high reduced water and high oxidized water are generated by supplying and discharging water to and from the cathode chamber 7 and the anode chamber 6 is the same as the conventional method.

  However, as described above, in the method using the three-chamber electrolyzed water generating apparatus, hydrochloric acid generated by the electrolysis of the salt water is not only taken out as electrolyzed water on the cathode side, but also returned to the salt water tank 2 from the intermediate chamber. Furthermore, it is stored in the salt water tank 2 along with the continuation of electrolysis, resulting in a high concentration. For this reason, various disadvantages as described above occur.

In contrast in this onset bright it is to add inhibit hydrochloric acid gas inhibitor generation of hydrochloric acid gas (hydrogen chloride) in saline to be introduced into the brine tank 2. In the examples described later, sodium hydrogen carbonate (NaHCO ₃ ) is used as a hydrochloric acid gas inhibitor, but for example, carbonate ions (CO ₃ ⁽² ) such as calcium carbonate (CaCO ₃ ) or potassium carbonate (K ₂ CO ₃ ). ^-) ), In these cases, it reacts with hydrochloric acid to produce either sodium chloride (NaCl), calcium chloride (CaCl ₂ ) or potassium chloride (KCl), water and carbon dioxide, respectively.

A display 56 is provided outside the right side wall 43 outside the display device 54. The display 56 is exposed to the outer surface by fitting and attaching the display device 54 to a flat recess 57 formed on the right side of the right side wall 43 as shown in the figure.

  A converter 31 serving as an overall control power source is mounted and installed on the inner bottom 44 on the back side of the electrolytic cell 1 at a substantially central position in the main body chamber 48. 58 is installed in the left-right direction, and a converter 28 serving as a power source for electrolytic operation is installed on the mounting shelf 58 between the top plate 47 on the upper side. An electrode changeover switch 29 is mounted on the inner bottom 44 near the front under the salt water pump 11.

Thus, the washing water and the sterilizing water are sequentially discharged from the extraction pipes 18b and 18a one after another.

  Distributing pipes 18a and 18b for sterilizing water and washing water are attached to the top plate 47 in the front-rear direction, and the various taking-out pipes 18a and 18b are metal spiral pipes that can be plastically deformed. A bracket 61 projects from the front and rear center position of the plate 47 to the right, and a left and right bar-shaped handle 62 is laterally disposed between the bracket 61 and the upper projecting end of the left side wall 42 to carry the device. Sometimes used as a handle.

  A pipe (hose) 17a for supplying water for generating electrolyzed water to the cathode chamber 7 and the anode chamber 6 or a connection port 63a of the same 17b is taken out at the lower position of both the front and rear walls of the electrolytic cell 1 and taken out at the upper position. A connecting port 63b for removing the generated water connected to the pipe 18a or 18b is provided, and a salt water supply (circulation) pipe from the salt water tank 2 is provided at the upper left position of the middle chamber 4 at the center in the front-rear direction.

  1 to 4 describe an example in which water for electrolytically generated water is connected to a water pipe, and washing water and sterilized water are taken out using water pressure, but the case 41 in FIGS. As indicated by the lower phantom line, the water supply tank 66 having a larger volume than that of the pipe chamber 49 is integrally provided at the lower portion of the case 41 without being provided with the piping chamber 49, and is supplied and stored through the water supply port 67. Water can be supplied to the anode chamber 6 and the cathode chamber 7 of the electrolytic cell 1 by a water supply pump (not shown) provided in the main body chamber 48. Since this type of device does not need to be connected to a water pipe, it can be used even in places where there is no water pipe, and has the advantage that it can be carried around anywhere.

  FIG. 5 is an example of the instruction content and flow displayed on the display 56 of the display device 54. The user can perform cleaning and sterilization according to this instruction, and the electrolytic function is kept below a certain level by repeatedly using the electrolyte. When the voltage drops, the replacement procedure is displayed and the electrolyte is replaced.

  1 (100%), 1 minute, 5 minutes, and 10 minutes after addition, the number of bacteria was negative for Pseudomonas aeruginosa, negative for Bacillus cereus, negative only after 10 minutes, others over time Although it shows a slight decrease, a large bactericidal effect is not recognized.

In contrast, the sterilized water (100%), the sterilized water (50%), and the tap water (50%) were all negative for each elapsed time (Shimane Environmental Insurance Corporation experiment).
The electrolyzed water produced by the method of this example also gave substantially the same results.

  Caregivers and nurses frequently wash their hands 20 to 30 times a day, but often use alcohol or isodine disinfection, but in these cases, rough skin is unavoidable. On the other hand, according to the experiment at the Department of Dermatology and Industry-Academia Research, Shimane University School of Medicine, it was possible to reliably prevent rough skin with the washing water and the sterilizing water according to the method of the present invention in comparison after 4 weeks.

  Next, the above-described method of the present invention is applied to the conventional large commercial electrolyzed water generating device (“business device” shown in FIG. 1 used for washing or washing clothes such as hospitals and nursing care facilities. )) And an example using the small-sized hand-washing electrolyzed water generating device (“hand device”) of the present invention shown in FIGS. 1 to 4. Table 1 shows the specifications of the two types of devices.

  FIG. 6 shows an electrolyte solution (saline solution) in the case where electrolyzed water is produced using a saturated saline solution and a solution to which sodium chloride and sodium bicarbonate (sodium bicarbonate) are added at a ratio of 3: 7, respectively, using the above two types of devices. ), Sterilized water, washing water hydrogen ion concentration (pH), redox potential (ORP), chlorine concentration (ppm) is a table showing the change over time.

  According to Table 1, there is no significant difference in the measured value of any target water except for the pH value of the electrolyte in the salt water tank in any of the devices. It is clear that both the devices were obtained by adding sodium bicarbonate to saline and having a high pH value compared to saline and neutralizing or weakly alkalizing.

That is, in the electrolyte in the salt water tank in the case of a commercial apparatus, the latter pH value shows strong acidity of 0.88 to 1.41 (high hydrochloric acid concentration), whereas the former pH value is 7.25. It is clear that it remains neutral or weakly acidic (no hydrochloric acid) at ~ 8.50.
Similarly, in the case of a device for fingers, saturated saline shows a strong acid having a pH value of 0.22 to 1.15, whereas a sodium salt added is 7.82 to 10.35 neutral to weakly alkaline. It is clear that it does not contain hydrochloric acid. The mixing ratio of sodium chloride and sodium bicarbonate is appropriately determined in consideration of the amount of hydrogen chloride generated, the total amount of electrolyte, the amount of electrolyte used, and the like.

  FIG. 7 is used in the method of the present invention, and particularly suitable for taking out washing water (reduced water) and disinfecting water (oxidized water) separately at different timings when used for hand washing / disinfection. It is provided as a device. That is, in the apparatus shown in FIG. 1, since the washing water and the sterilizing water are provided by a single three-chamber electrolysis tank 1, when one of the electrolyzed water is generated and taken out, the other electrolyzed water is always generated. As a result, when only one of them is used, the other water is wasted, and when one of the acid and alkali concentrations (pH) is determined, the other is automatically determined accordingly. However, there is a problem that one cannot be adjusted with respect to the other.

  This embodiment corresponds to the above-described problem. As shown in FIG. 7, the electrolytic cell 1 is divided into an electrolytic cell (acidic electrolytic cell) 1A for generating sterilized water and an electrolytic cell (reducing electrolytic layer) 1B for generating cleaning water. It is divided and formed. Each electrolytic cell 1A, 1B is inserted with a positive electrode 8a and a negative electrode 8b, which are arranged close to the ion-permeable diaphragm 8a or 8b, and water to be electrolyzed water is introduced into and discharged from both sides to generate an electrolyzed water generation chamber. The point which forms (the anode chamber 6 or the cathode chamber 7) and the point which each electrolyte solution chamber 4a, 4b is connected with the salt water tank 2, and is supplied while circulating a salt solution are common.

  On the other hand, in both electrolytic cells 1A and 1B, the diaphragm 3a on the acidic electrolytic cell 1A side is an anion exchange membrane, the anode chamber 6 is formed on the positive electrode 8a side, and the electrolyte chamber 4a is formed on the negative electrode 8b side. In contrast, the diaphragm 3b is a cation exchange membrane on the reducing electrolytic cell 1B side, the cathode chamber 7 is formed on the negative electrode 8b side, and the electrolyte chamber 4b is formed on the positive electrode 8b side. Different. In other words, in the apparatus shown in this example, the electrolyte chamber (intermediate chamber) 4 of the three-chamber type apparatus shown in FIG. 1 is divided into left and right parts 4a and 4b, and each of the electrolyte chambers 4a and 4b has salt water. The electrolyzed water generation function is substantially the same as that of the three-chamber type device.

  Corresponding to the above configuration, electromagnetic valves 22a and 22b are provided on the upstream side of the water supply branch pipes 17a and 17b connected to the electrode chambers 6 and 7, respectively, the two electrolyte chambers 4a, 4b is connected to the circulation passages 9a and 9b in a branched manner, and each branch pipe of the circulation passage 9a on the liquid supply side is provided with valves 12a and 12b for adjusting the flow rate, respectively. Electrolytic circuits 24a and 24b are branched and connected to 1A and 1B, and the switch for switching electrodes is divided into two stages as shown in 29a and 29b along with branching to electrolytic circuits 24a and 24b. 1 is different from the electrolyzed water generating device of FIG. 1 in that the electrodes of both electrolytic cells 1A and 1B can be selected and operated separately. Except for the above differences, reference numerals common to the apparatus of FIG. 1 represent parts or parts having the same functions as those of the apparatus of FIG.

  The apparatus shown in FIG. 7 is configured as described above. As a result, in the acidic electrolyzer 1A and the reducing electrolyzer 1B, acidic water (sanitized water) and reduced water (washing water) are influenced by the other independently. There is an advantage that it can be generated separately and can be generated and taken out independently, and the pH concentration and flow rate of both product water can be adjusted independently according to the purpose of use, and it is a device for hand washing and disinfection Also suitable.

  In this embodiment as well, since the salt water as the electrolyte is stored in the salt water tank 2 and circulates between the electrolytic cells 1A and 1B, an inhibitor that suppresses the generation of hydrochloric acid gas is supplied to the salt water tank 2. Of course, the generation of hydrochloric acid gas can be suppressed.

Equipment of the present invention can utilize the various operations of cleaning and disinfection, and manufacture of the device is one which itself suitable for industrial production.
