Description

Electrolyzed water generating method, electrolyzed water generating sprayer and electrolyzed water generating spray device

The present invention relates to a method for generating electrolyzed water from raw water by electrolysis, a generating sprayer, and a generating spray device.

Although ozone (O ₃ ) has a strong oxidizing power, it changes to oxygen (O ₂ ) after tens of minutes in an aqueous solution, so there is little residual toxicity. Therefore, today, ozone gas, or ozone aqueous solution, that is, ozone water is used in a wide range of fields such as sterilization, deodorization, decolorization, oxidation and decomposition of harmful substances, and has attracted attention as an oxidant instead of chlorine, especially a fungicide. . Ozone-based sterilization is effective in a wide range of bacteria, yeasts, molds, viruses, etc., and because its mechanism of action is to oxidize and destroy the cell membrane of bacteria, it has the characteristics of being difficult to produce resistant bacteria and having deodorizing effects. On the other hand, because ozone has an odor and irritates the respiratory system of the human body, it is necessary to pay attention to the indoor air quality standard (volume concentration below 0.1ppm) that the concentration in the air must be observed, or ozone can cause iron or carbon dioxide. Corrosion or deterioration of nitrile rubber, etc. (Non-Patent Document 1).

As the main production method of ozone water, there are gas dissolution method and direct electrolysis method. The gas dissolution method is a method of producing ozone water by dissolving ozone gas produced by a method such as generating by electric discharge using oxygen as a raw material in water. Since ozone gas is hard to dissolve in water, it has the disadvantage that it is difficult to obtain high-concentration ozone water. Therefore, the gas dissolution method is mostly used for low concentrations below 1 mg/L. Direct electrolysis is a method of generating ozone water by electrolyzing raw water such as tap water. By direct electrolysis, high-concentration ozone water can be obtained more economically (same document).

In Japanese Patent Laid-Open No. 2003-93479 (Patent Document 1), as shown in Figure 21, it is disclosed that ozone is generated by electrolyzing raw water in a bottle that can be held by one hand in a way that can be easily used at home. The basic structure of a simple ozone water generating sprayer that can spray 0.1mL~1mL at a time. The ozone water generating sprayer is composed of a discharge part 107 and a bottle 104. The bottle 104 has electrodes 105 and 106 erected on its flat inner bottom surface to electrolyze the raw water to generate ozone water. The ozone generated in the bottle 104 The water is sprayed from the discharge part 107 through the spray tube 112. The same basic composition is also disclosed in Japanese Patent Application Publication No. 2019-037946, Japanese Relisted Publication No. 2003-000957, and Japanese Patent Application Publication No. 2003-266073.

In such a simple household-use ozone water generating sprayer, it is a problem to efficiently generate ozone water with a volume of tens of mL and an ozone concentration of about 1 to 2 mg/L in a short time of about 2 to 4 minutes. Of course, although high-concentration ozone water with an ozone concentration of 4 mg/L or more can be generated by increasing the current value or voltage value during electrolysis, the pungent odor is strong when sprayed and when it is continuously generated depending on the conditions, so Practical in the family intolerant. As the prior art using direct electrolysis to improve the efficiency of ozone water generation, (1) arranging electrodes in the zone, (2) design of the electrode surface, (3) control of ion movement, (4) control of convection Wait.

(1) Arrange electrodes in the zone The above-mentioned technology is a technology in which partitions are arranged in the container for storing raw water, and electrodes for electrolysis are arranged in the partitions to perform electrolysis, and only the high-concentration ozone water generated in the partitions is sprayed. For example, as shown in FIG. 22, Japanese Patent Application Laid-Open No. 2009-154030 (Patent Document 2) discloses that an electrolyzed water generating spray device 201 is provided with an electrolytic tank 205 connected to a tank 204, and the tank 204 is connected to the electrolytic tank. The 205 system is configured to communicate only with the communication path 207, and each time the spray mechanism 203 is pressed by hand, ozone water is sprayed from the spray nozzle, and at the same time, the raw material water flows from the tank 204 through the communication path 207 into the small-capacity electrolytic cell 205. It is a technology of electrolyzing in the electrolytic tank 205 and generating high-concentration electrolyzed water in the electrolytic tank 205 again. A similar technique is also disclosed in Japanese Patent Application Publication No. 2011-092883. In addition, Japanese Patent No. 6249200 or Japanese Patent Application Publication No. 2004-148109 discloses a technique for installing an electrolysis unit that generates ozone water inside the spray tube. In addition, Japanese Patent Laid-Open No. 2003-062573 or Japanese Patent Laid-Open No. 2003-181338 discloses a technique of installing an electrode for electrolysis for generating ozone water in the discharge part very close to the spray nozzle. In these technologies, the amount of ozone water that can be stored in the partitioned part is small. Therefore, if the spray amount per unit time exceeds a certain value, the generation speed of ozone water cannot catch up with the spray speed. The disadvantage of reducing the ozone concentration in the water.

(2) Design of electrode surface The above technology is a technology to improve the efficiency of ozone water generation by designing the shape of the electrode or the material on the electrode surface. For example, in Japanese Patent No. 6258566, it is disclosed that in order to increase the contact area with the raw material water and improve the electrolysis efficiency, the invention of making the anode and/or cathode into a mesh is disclosed. In addition, the Japanese Rebroad Publication No. 03-000957 discloses a technique for improving the efficiency of ozone generation by using an electrode for electrolysis having an electrode catalyst composed of tantalum oxide or niobium oxide on the surface. In addition, Japanese Patent Laid-Open No. 08-134677 discloses that a metal mesh made of noble metal with the function of an ozone generating catalyst is used for the anode electrode, and a lath made of corrosion-resistant metal is overlapped on the outer surface of the anode electrode. The net feeds the raw water so that the raw water travels through the narrow gap that connects the meshes to each other. Through its stirring action, the generated ozone bubbles are dissolved in the water to prevent the ozone from being discharged as a gas. , Technology to improve the efficiency of ozone water production. Although these technologies are useful, the electrode structure is often complicated and the manufacturing cost becomes high.

(3) Control of ion movement The above-mentioned technology is a technique to improve the efficiency of ozone water generation by controlling the movement of ions near the electrode. Generally speaking, in the direct electrolysis method, as shown in the following chemical reaction formula, the electrolysis reactions (Equation 1) and (Equation 3) of water that _{generate oxygen (O 2} ) and hydrogen (H _{2) are the main ones. Furthermore,} The reaction (Equation 2) that generates a small amount of ozone (O _{3) is accompanied.} [Anodic reaction] (Formula _{1) 2H 2 O → O 2} + 4H + + 4e - ( Formula _{2) 3H 2 O → O 3} + 6H + + 6e - [ cathode reaction] (Formula 3) 2H ^{+ +} 2e ^- → H ₂ can be seen from (Equation 2) that if hydrogen ions (H ⁺ ) generated at the anode by the electrolysis of raw water stay near the anode and exist in a high concentration, it will hinder the progress of the ozone generation reaction (Equation 2). In the above-mentioned Patent Document 2, an electrolysis unit in which an anode and a linear cathode are partitioned by a cation exchange membrane is disclosed. The hydrogen ions generated at the anode travel to the cathode through the cation exchange membrane, and accept electrons at the cathode as shown in (Equation 3) to become hydrogen (H ₂ ). As a result, since hydrogen ions do not stay in the vicinity of the anode in a high concentration, ozone can be produced efficiently. In addition, Japanese Patent No. 4723627 and the above-mentioned Japanese Patent No. 6258566 also disclose a membrane-electrode structure in which an anode and a cathode are partitioned by a cation exchange membrane. However, in ion exchange membranes, the structure of the membrane-electrode structure often becomes complicated, and maintenance and management costs are required.

(4) Convection control The above technology is a method of spraying high-concentration ozone water (or electrolyzed water) by controlling the convection of the raw water.

In Japanese Publication No. 3207605 (Patent Document 3), as shown in FIG. 23, an invention of a sprayer is disclosed. Counting from the top, the decorative sheet 331 with a plurality of holes, the negative electrode electrolytic sheet 332, the insulating spacer 333, and the positive electrolytic sheet 334 are laminated, and the decorative sheet 331 and the holder 340 are thermally fused, whereby the aforementioned electrode member is accommodated It is fixed to the holder 340. In this invention, the holder 340 for generating electrolyzed water is formed in a cylindrical shape with a short height and a wide bottom area to suppress convection generated in the container 320 during electrolysis. The water suction port of the spraying pipe is set nearby, which can spray the electrolyzed water with high concentration if it is a small amount. However, since the convection in the container 320 is weak, there is a disadvantage that only the concentration of the electrolyzed water near the holder 340 increases, and the concentration of the entire container 320 does not increase so much.

In Japanese Unexamined Patent Publication No. 2003-334557 (Patent Document 4), as shown in FIG. 24, an invention of a sterilizing and clean water generating device is disclosed. The slot 402 and the power supply device 404 are detachable. In order to penetrate the electrode portion 401 in the electrolytic cell 402, a terminal cover portion 415 having an anode power receiving terminal 405-1 and a cathode power receiving terminal 405-2 is provided under the electrolytic cell 402. Therefore, the horizontal section of the lower part of the electrolytic cell 402 is smaller than that of the upper part. During electrolysis, the raw material water in the electrolytic cell 402 generates an upward flow from the electrode portion 401 and a downflow mainly along the inner surface of the electrolytic cell 402. The descending water flow finally reaches the inner bottom surface of the electrolytic cell 402. However, since there is a vertical gap between the inner bottom surface of the electrolytic cell and the electrode section 401, the above-mentioned descending water flow does not directly contact the electrode section 401, so the electrolyzed water with a low concentration contained in the descending water flow is electrolyzed and becomes It takes time to increase the concentration. In addition, since the electrode portion 401 is aligned in the horizontal direction, compared with the case where the alignment is in the vertical direction, the volume of the raw material water affected by the Joule heating and the generation of microbubbles is larger. Accordingly, the flow velocity of the water flow is increased. It also slows down, and it is easier to conflict with the descending current and slow down the speed of convection. In addition, if the electrode portion 401 is aligned in the horizontal direction, since the microbubbles generated by electrolysis accumulate and stay in the lower half of the substantially cylindrical surface of the electrode portion 401, the effective area of the electrode is reduced by about half, so , The generation rate of electrolyzed water is significantly reduced. There is much room for improvement in the configuration and alignment of the electrode portion 401 in the electrolytic cell 402.

In Japanese Patent Laid-Open No. 2017-05191 (Patent Document 5), as shown in FIG. 25, the invention of an electrolytic device is disclosed. The main body, the electrode part 520 arranged in the electrolytic cell 510, and the power supply part 530 for supplying power to the electrode part 520. The power supply part 530 is installed on the main body and extends from the main body to the bottom surface of the electrolytic cell 510, The electrode part 520 is installed in the power supply part 530. There are gaps D1 and D2 between the electrode part 520 and the inner and bottom surfaces of the electrolytic cell 510. A peripheral part 524 is arranged on the outer surface of the electrode part 520. A concentric groove portion 525 is provided, and the lower surface side is open, and water can circulate in the electrode portion 520 along the axial direction. The gap D2 is formed in the electrolysis device, whereby the water flow that flows upward through the electrode portion 520 due to the temperature rise of the electrolyzed water accompanying the electrolysis treatment can be generated, and the electrode portion 520 can be efficiently supplied with the water before the electrolysis treatment. . In addition, by forming the gap D1, the water stored above the electrode portion 520 before the electrolysis treatment can circulate under the electrode portion 520 through the electrode portion 520 and the side surface of the electrolytic cell 510, and from the electrode portion 520 The electrode part 520 is replenished below. Thereby, since the water in the electrolytic cell 510 can be circulated to the electrode part 520 efficiently, the efficiency of the electrolysis treatment can be improved, and the time required for the electrolysis treatment can be shortened. However, in this electrolytic device, the electrode part hangs down from the main body part and the power source part is provided in the main body part. Therefore, there is a disadvantage that the main body part constituting the cover of the electrolytic cell becomes heavy and the operation is inconvenient.

(5) Other In the above-mentioned Japanese Patent No. 6249200, although it is disclosed that an electrolysis unit that generates ozone water is installed inside the spray tube, and a small spiral structure is installed inside the spray tube, thereby, It is a technology that breaks the ozone bubbles generated in the electrolysis unit and transforms them into fine bubbles to increase the dissolution rate of ozone and increase the efficiency of ozone water generation. However, its structure is complicated and maintenance is troublesome. Although it is not a technology to improve the efficiency of ozone water production, it is disclosed in Japanese Special Publication No. 2012-501358 that the display lamp is turned on when the current value flowing to the electrolysis cell is within a predetermined range, and when the current value is outside the range, it is turned on. The technology to show the lights to turn off the lights. In addition, in Japanese Patent Application Publication No. 2006-518666 (Patent Document 6), although the spray head has a spray device with an oxidant effectiveness indicator lamp for displaying the effectiveness of electrolyzed water, there is no description about the use of Oxidizer effectiveness shows the details of the control of the lights on and off.

In this way, in order to use the ozone water generating sprayer (or electrolyzed water generating sprayer) with a bottle held by one hand for simple and low-cost household use, the direct electrolysis method is used to improve the production efficiency of ozone water (or electrolyzed water) The previous technologies (1) ~ (5) are not perfect technologies. Moreover, none of the technologies have the ability to design the shape of the inner bottom surface of the container for storing raw water, etc., to control the rising water flow generated from the vicinity of the electrode structure installed on the inner bottom surface of the container during electrolysis, and the generation along the inner surface of the container. The idea of the flow of precipitation stream underneath to improve the production efficiency of ozone water (or electrolyzed water). For example, in Patent Document 4, although the structure of the inner bottom surface of the container is disclosed that the inner bottom surface is not flat, it is for the purpose of piercing the electrode part on the side of the container, not for controlling the water flow in the container. In addition, in Patent Document 5, although the concept of controlling the flow of the rising water flow and the falling water flow in the container can be seen, there is no concept of controlling the flow of the container by designing the shape of the inner bottom surface of the container. Furthermore, it has not been realized to display the effectiveness of the sprayed ozone water (or electrolyzed water) for sterilization and deodorization in an instant and in a user-friendly way.

[Effects of the invention]

According to the first aspect of the present invention, it is possible to provide an electrolyzed water generating method for an electrolyzed water generating sprayer, the electrolyzed water generating sprayer having at least a container for storing raw water and an electrolysis for spraying the raw water in the container A water spray mechanism; an electrode structure is erected on the inner bottom surface of the container; on the inner bottom surface of the container, or at the lower part of the electrode structure facing the inner bottom surface of the container, provided to promote the inside of the container The convection promoting means of the convection of the raw material water; the electrolyzed water is generated by applying a voltage to the electrode structure and electrolyzing the raw water; generating the raw material water that acts on the electrode structure in the vertical direction during electrolysis The rising water flow generated by the buoyancy, and the raw material water flowing down toward the inner bottom surface of the container, the downward precipitation flow, the convection promotion means promotes the convection of the raw material water in the container, and the raw material water is supplied to the electrode structure , Carry out electrolyzed water generation reaction based on electrolysis, and increase the concentration of electrolyzed water produced.

When there is no convection promotion means on the inner bottom surface of the container or the lower part of the electrode structure facing the inner bottom surface of the container, the convection promotion means to promote the convection of the raw water in the container is provided, because there is only the aforementioned rising water flow, There is no means to promote the flow of raw water toward the bottom of the container. Therefore, the convection of the raw water in the container is weak. The raw water circulates locally in the container, and the generated ozone water (or electrolyzed water) stays in the container. In the lower part, the raw material water with low ozone concentration (or electrolysis product concentration) supplied to the electrode structure decreases. Therefore, the ozone concentration (or electrolysis product concentration) of the raw water in the electrode structure becomes high, and the ozone generation reaction (or electrolysis water generation reaction) shown in (Equation 2) does not proceed much. In contrast, when the inner bottom surface of the container or the lower part of the electrode structure facing the inner bottom surface of the container is provided with a convection promotion means to promote the convection of the raw water in the container, in addition to the aforementioned rising water flow In addition, the raw material water flows down toward the inner bottom surface of the container and the precipitation flow is promoted. The convection of the raw material water in the container becomes stronger, the raw material water in the container circulates on a large scale, and the raw material water with low ozone concentration (or electrolysis product concentration) It is supplied abundantly to the electrode structure. Therefore, the ozone concentration (or electrolysis product concentration) of the raw material water in the electrode structure becomes lower, and the ozone generation reaction (or electrolysis reaction) shown in (Equation 2) proceeds to efficiently produce ozone water (or electrolysis water) ), the generated ozone water (or electrolyzed water) with high ozone concentration (or electrolysis product concentration) spreads over the entire container by the aforementioned rising water flow and the aforementioned falling water flow. In addition, although the cause of the aforementioned rising water flow is buoyancy, the buoyancy is generated by the following reasons, that is, the temperature of the raw water in the electrode structure rises due to the increase in the temperature of the raw material water in the electrode structure and the thermal expansion is caused by the Joule heating accompanying electrolysis, and Since fine bubbles of oxygen, hydrogen, ozone, and other gases generated along with electrolysis are mixed into the raw material water, the actual density of the raw material water decreases.

In this form, the electrode structure system is erected on the inner bottom surface of the container. The so-called "upright installation" means that the surface direction of the electrode constituting the electrode structure becomes the direction intersecting the inner bottom surface of the container (preferably the vertical direction), and the electrode structure is installed on the member having the inner bottom surface as its surface The meaning of the body. Since the electrode structure is erected, the raw material water continuously receives buoyancy while traveling from the bottom to the top in the electrode structure, and a strong rising water flow is generated.

In addition, as the raw material water in the present invention, from the viewpoint that it can be easily used at home, tap water or commercially available mineral water is mainly conceivable, but it is not limited to this. From the viewpoint of the speed of ), it may also be an aqueous solution in which a gas such as chlorine or a salt such as sodium chloride is dissolved in water, or it may be distilled water, deionized water, purified water, etc. Regarding the electrolyzed water (or ozone water) produced by the electrolysis of raw water, it is not limited to ozone, and may be various substances such as chlorine, hypochlorous acid, chlorous acid, sodium hydroxide, oxygen, hydrogen, sodium chloride, etc. Or an aqueous solution in which the electrolysis product is dissolved in water.

According to the second aspect of the present invention, there can be provided a method for producing electrolyzed water, wherein the convection promoting means is provided with a recessed basin portion on the inner bottom surface of the container, and the recessed basin portion is formed by the bottom surface of the recessed basin and The electrode structure is erected on the bottom surface of the recessed basin in the container; the wall surface of the recessed basin of the recessed basin faces the bottom surface of the recessed basin by the raw water Flow down to promote the aforementioned descending water flow.

When a concave basin portion is provided on the inner bottom surface of the container as the aforementioned convection promotion means, in addition to the aforementioned rising water flow, due to the presence of raw water flowing down the concave basin wall surface of the concave basin portion toward the bottom surface of the concave basin portion Therefore, the raw material water flows down toward the inner bottom surface of the container and the precipitation flow is promoted. The convection of the raw material water in the container becomes stronger. The raw material water in the container circulates on a large scale. It is supplied abundantly to the electrode structure. Therefore, the ozone concentration (or electrolysis product concentration) of the raw material water in the electrode structure becomes lower, and the ozone generation reaction (or electrolysis reaction) shown in (Equation 2) proceeds to efficiently produce ozone water (or electrolysis water) ), the generated ozone water (or electrolyzed water) with high ozone concentration (or electrolysis product concentration) spreads over the entire container by the aforementioned rising water flow and the aforementioned falling water flow.

In this form, the electrode structure system is erected on the bottom surface of the concave basin. The so-called "upright installation" means that the surface direction of the electrode constituting the electrode structure becomes the direction intersecting the bottom surface of the recessed portion (preferably the vertical direction), and the electrode is installed on the member having the bottom surface of the recessed portion as its surface. The meaning of the structure. Since the electrode structure is erected, the raw material water continuously receives buoyancy while traveling from the bottom to the top in the electrode structure, and a strong rising water flow is generated.

According to an example of the second aspect of the present invention, there can be provided a method for producing electrolyzed water, wherein the wall surface of the recessed bowl portion is perpendicular to the bottom surface of the recessed bowl portion. The concave portion in this example can be easily manufactured by machining methods such as cutting and injection molding. According to another example of the second aspect of the present invention, there can be provided a method for producing electrolyzed water, wherein the wall surface of the recessed portion is an inclined surface. In this example, since the wall surface of the recessed basin is formed of a slope, the raw material water that descends along the inner surface of the container can be smoothly moved to the bottom of the recessed basin and the electrode structure erected on the bottom of the recessed basin. Guide, and can efficiently generate high-concentration electrolyzed water. According to still another example of the second aspect of the present invention, there can be provided a method for producing electrolyzed water, wherein the wall surface of the recessed portion and the inner surface of the container are smoothly connected. In this example, since the wall surface of the recessed basin is smoothly connected to the inner surface of the container, the raw material water that descends along the inner surface of the container can be smoothly moved to the bottom of the recessed basin and erected on the recessed basin. The electrode structure on the bottom is guided to efficiently generate high-concentration electrolyzed water.

According to a third aspect of the present invention, there can be provided a method for producing electrolyzed water, wherein the electrode structure includes an anode member and a cathode member arranged with an electrode gap between the anode member and the anode member; and the convection promoting means is connected to The inner bottom of the container faces an opening formed between the lower portion of the cathode member facing the container and the inner bottom surface of the container; the raw water flows into the electrode gap through the opening to promote the descending water flow.

In this form, an opening formed between the lower portion of the cathode member facing the inner bottom surface of the container and the inner bottom surface of the container is provided as a convection promoting means, through which the raw water can flow into The electrode gap of the electrode structure. Therefore, the raw material water flows into the electrode gap of the electrode structure through the opening portion along with the rising water flow generated in the electrode gap of the electrode structure during electrolysis. Therefore, the raw material water flows down toward the inner bottom surface of the container.

Generally speaking, if electrolyzed water is produced by electrolysis for a period of time, the sterilization and deodorization effects will gradually disappear. The electrolyzed water generating spray device of this form uses a lamp to display whether the ozone water (or electrolyzed water) in the container has sufficient ozone concentration (or electrolyzed product concentration) in a way that is easy for users to understand Use spray to sterilize and deodorize.

The second generation button 64c. Although long-term generation is the standard, short-term generation can be performed in urgent situations. In this way, by setting a plurality of water level lines, it is possible to reduce the water volume of the raw material water 43 used as the object of electrolysis when it is generated in a short time and when it is generated in a longer time, and the ozone concentration of the generated ozone water (or electrolyzed water) ( Or the concentration of electrolysis products) is kept high.

<Concave Basin> FIG. 4 is a perspective view showing a state where the electrode structure 2 of the ozone water generating sprayer 1 is erected on the inner bottom surface 46 of the container 4 in one embodiment of the present invention. The inner bottom surface 46 of the container 4 has a recessed basin 48. The recessed basin 48 is composed of a recessed basin bottom surface 48a and a surrounding recessed basin wall surface 48b, standing on the recessed basin bottom surface 48a in the container 4 An electrode structure 2 is provided. In addition, the electrode structure support frame 28 is erected on the inner bottom surface 46 of the container 4. In this embodiment, the recessed basin 48 constitutes the convection promoting means 46c. The ozone water generating sprayer 1 can generate ozone water (or electrolyzed water) 42 by applying a voltage to the electrode structure 2 and electrolyzing the raw material water 43. The rising water stream 81 generated by the buoyancy of the water 43 and the raw material water 43 flow down the concave basin wall surface 48b toward the concave basin bottom surface 48a, and the downward precipitation flow 82 promotes the convection of the raw material water 43 in the container 4 and supplies the electrode structure 2 The raw material water 43 undergoes an ozone generation reaction (or electrolysis water generation reaction) based on electrolysis to increase the ozone concentration (or electrolysis product concentration) in the generated ozone water (or electrolysis water) 42. Since the electrode structure 2 is supported by the "匚"-shaped electrode structure support frame 28 by embedding or the like, there is less fear of damage such as collapse or breakage when cleaning with a brush during maintenance.

<Effect of the recessed basin> FIG. 5 is a cross-sectional explanatory view for explaining the function and effect of the recessed basin 48 provided on the inner bottom surface 46 of the container 4. Figure (5A) shows an embodiment of the present invention, and Figure (5B) shows the prior art. In the present invention, as shown in Figure (5A), a concave basin 48 is provided on the upper surface of the container bottom plate 49 of the container 4, that is, the inner bottom surface 46. The concave basin 48 is formed by the concave basin bottom surface 48a and the surrounding concave The basin wall surface 48b is constituted, and the electrode structure 2 is erected on the bottom surface 48a of the recessed basin portion in the container 4. Ozone water (or electrolyzed water) 42 is generated by applying a voltage to the electrode structure 2 and electrolyzing the raw material water 43. During electrolysis, the rising water flow 81 generated by the buoyancy of the raw material water 43 acting in the vertical direction in the electrode structure 2 can be generated. The raw material water 43 flows down the concave basin wall surface 48b toward the concave basin bottom surface 48a. The partial downward water flow 82a and the raw material water 43 descend along the inner side 47 of the container 4 and the downward precipitation flow 82 promotes the convection of the raw material water 43 in the container 4, and supplies the electrode structure 2 with a low ozone concentration (or electrolysis product concentration) The raw material water 43 undergoes an ozone generation reaction (or electrolysis water generation reaction) based on electrolysis to increase the ozone concentration (or electrolysis product concentration) in the generated ozone water (or electrolysis water) 42.

On the other hand, in the prior art, as shown in FIG. 5B, the inner bottom surface 46 of the container 4 is not provided with the recessed portion 48, and the electrode structure 2 is erected on the flat inner bottom surface 46. Therefore, during electrolysis, although there is an ascending water flow 81 generated by the buoyancy of the raw material water 43 acting in the vertical direction on the electrode structure 2, there is no sink portion descending water flow 82a. Accordingly, the raw material water When 43 descends along the inner side surface 47 of the container 4, the precipitation flow 82 becomes weak, and the water flow 82b flowing to the bottom of the electrode structure 2 is also weak. Therefore, the convection of the raw material water 43 in the container 4 becomes weak, and the generated ozone water (or electrolyzed water) 42 will stay at the bottom of the container 4 where the electrode structure 2 exists, and the ozone concentration (or electrolysis product concentration) is low. The raw material water 43 is not sufficiently supplied to the electrode structure 2, and the ozone generation reaction (or electrolysis water generation reaction) by electrolysis does not proceed so much, and the ozone concentration in the generated ozone water (or electrolysis water) 42 cannot be sufficiently increased ( Or electrolysis product concentration).

The rising water stream 81 generated by the buoyancy of the raw material water 43 and the downward precipitation stream 82 of the raw material water 43 flowing down toward the inner bottom surface 46 of the container 4 are promoted by the convection promoting means 46c, that is, the cathode opening 26o. The convection of 43 supplies the raw material water 43 to the electrode structure 2 to perform the electrolyzed water production reaction by electrolysis, and increase the concentration of the produced electrolyzed water 42. Here, the effect of the cathode opening 26o is as follows. In this embodiment, the opening formed between the lower portion of the cathode member 22 facing the inner bottom surface 46 of the container 4 and the inner bottom surface 46 of the container 4, that is, the cathode opening 26o, is used as the convection promoting means 46c. It is assumed that the raw material water 43 can pass through the cathode opening 26o and flow into the electrode gap 23 of the electrode structure 2 in a form in which the water flow 82o flows into the opening. Therefore, due to the rising water flow 81 generated in the electrode gap 23 of the electrode structure 2 during electrolysis, the raw material water 43 can flow into the electrode gap of the electrode structure 2 through the cathode opening 26o in the form of an opening inflow water flow 82o. 23. Therefore, the raw water 43 flows down toward the inner bottom surface 46 of the container 4 and the precipitation flow 82 is promoted. The convection of the raw water 43 in the container 4 becomes stronger, and the raw water 43 in the container 4 circulates on a large scale. The ozone concentration (or electrolysis) The raw material water 43 with a low product concentration) is abundantly supplied to the electrode structure 2. Therefore, the ozone concentration (or electrolysis product concentration) of the raw material water 43 in the electrode structure 2 becomes lower, and the ozone generation reaction (or electrolysis reaction) shown in (Equation 2) proceeds to efficiently generate ozone water (or Electrolyzed water 42, ozone water (or electrolyzed water) 42 with high generated ozone concentration (or electrolysis product concentration) is spread over the entire container 4 by the rising water flow 81 and the falling water flow 82.

<Combination form of opening and recessed basin> FIG. 20 is an explanatory diagram of an embodiment of the present invention in which the recessed basin and the opening are used in combination. Figure (20A) is a front view, and Figure (20B) is a cross-sectional view in the C-C' section of Figure (20A). Since the horizontal cross-sectional view of the electrode structure 2 is the same as that of FIG. (19C), it is omitted. In the present embodiment, the electrode structure 2 of the ozone water generating sprayer 1 is erected on the upper surface of the container bottom plate 49 of the container 4, that is, the inner bottom surface 46. . The recessed basin 48 is composed of a recessed basin bottom surface 48a and a recessed basin wall surface 48b surrounding it. The raw water 43 can flow down from the recessed basin wall surface 48b of the recessed basin 48 toward the recessed basin bottom surface 48a. The electrode structure 2 includes an anode member 21 and a cathode member 22, and is arranged with an electrode gap 23 interposed between the anode member 21 and the anode member 21. The anode member 21 has an anode connecting protrusion 25 that is attached to the container bottom plate 49 in a penetrating state, and an anode leg portion 25 z that is attached to the container bottom plate 49. The cathode member 22 has a cathode connecting protrusion 26 attached to the container bottom plate 49 in a penetrating state, and one or more cathode legs 26 z attached to the container bottom plate 49. The substance constituting the cathode leg portion 26z and the substance constituting the cathode leg portion 26z of the cathode member 22 may be the same or different. Between the lower portion of the cathode member 22 facing the bottom surface 48a of the recessed portion and the bottom surface 48a of the recessed portion, there are formed the lower portion of the cathode member 22, the recessed portion bottom surface 48a, the cathode connecting protrusion 26, and the cathode leg portion. An opening formed by dividing the boundary at 26z, that is, one or more cathode openings 26o. In this embodiment, the recessed basin 48 and the cathode opening 26o constitute a convection promoting means 46c. In this embodiment, it is also possible to use various modifications that are the same as those described for the embodiment shown in FIG. 19, that is, the support by the electrode structure support frame 28 of the electrode structure 2 and the support frame The opening 28a, the linear insulating spacer 30, the plurality of holes 27 provided in the cathode member 22, and various types of electrode structures described below using FIGS. 12 to 18. In addition, with respect to the recessed basin 48, various forms of recessed basins described with reference to Figs. 6 and 7 can also be used. For example, the wall surface 48b of the recessed portion is not limited to a vertical surface, and may be an inclined surface or a multi-step surface. Furthermore, in this embodiment, between the lower portion of the anode member 21 facing the bottom surface 48a of the recessed portion and the bottom surface 48a of the recessed portion, the lower portion of the anode member 21, the recessed portion bottom surface 48a, The anode connecting protrusion 25 and the anode leg 25z are the opening formed by dividing the boundary, that is, the anode opening 25o. However, like the anode member 21 in the embodiment shown in FIG. 19, the lower part of the anode member 21 and the recess The basin bottom surface 48a abuts, or the lower part of the anode member 21 is embedded in the recessed basin bottom surface 48a, and there is no deformed form of the anode opening 25o.

<The effect of the combined use of the opening and the basin> In the present embodiment, the electrolyzed water 42 can be generated by applying a voltage to the electrode structure 2 provided on the bottom surface 48a of the basin and electrolyzing the raw water 43. During electrolysis, the rising water flow 81 generated by the buoyancy of the raw material water 43 in the electrode structure 2 in the vertical direction, and the raw material water 43 flow down toward the inner bottom surface 46 of the container 4, and the lower precipitation flow 82, by means of convection promotion means 46c. The recessed portion 48 and the cathode opening 26o promote the convection of the raw material water 43 in the container 4, supply the raw material water 43 to the electrode structure 2 to perform electrolyzed water production reaction based on electrolysis, and increase the concentration of the produced electrolyzed water 42. Here, the effect of combining the bottom surface 48a of the recessed portion and the cathode opening 26o is as follows. In this embodiment, the openings formed between the lower portion of the cathode member 22 facing the bottom surface 48a of the recessed portion and the inner bottom surface 46 of the bottom surface 48a of the recessed portion, that is, the cathode opening 26o and the recessed portion 48, It is provided as the convection promotion means 46c, and the raw material water 43 can flow into the electrode gap 23 of the electrode structure 2 through the cathode opening 26o in a form of the water flowing 82o in the opening. Therefore, with the rising water flow 81 generated in the electrode gap 23 of the electrode structure 2 during electrolysis, the raw material water 43 flows into the electrode gap 23 of the electrode structure 2 through the cathode opening 26o, so the raw material water 43 is in the recessed basin. The recessed basin wall surface 48b of the portion 48 flows down toward the recessed basin bottom surface 48a. The recessed basin descending water flow 82a, and the raw material water 43 flows down toward the inner bottom surface 46 of the container 4, and the lower precipitation flow 82 is promoted, and the raw material water 43 in the container 4 The convection becomes stronger, the raw material water 43 in the container 4 circulates on a large scale, and the raw material water 43 with a low ozone concentration (or electrolysis product concentration) is supplied to the electrode structure 2 in abundance. Therefore, the ozone concentration (or electrolysis product concentration) of the raw water 43 in the electrode structure 2 becomes low, and the ozone generation reaction or electrolysis water generation reaction shown in (Equation 2) progresses to efficiently generate ozone water (or Electrolyzed water 42, ozone water (or electrolyzed water) 42 with high generated ozone concentration (or electrolysis product concentration) is spread over the entire container 4 by the rising water flow 81 and the falling water flow 82.

<The structure of the lower part of the ozone water generating sprayer> Figure (3A) is a cross-sectional explanatory view showing the structure of the lower part of the ozone water generating sprayer 1 and the structure of the power supply unit 6 which is one embodiment of the present invention. The power supply unit 6 has a power supply cord 61 a, a control unit 63, an operation button 64, an indicator lamp 65, and an electrode unit 62.

The electrode structure 2 extends from the container bottom plate opening 49 a to the inside of the container 4, that is, upward, and its height is higher than the upper surface of the container bottom plate 49 of the container 4.

The shape of the opening 49a of the container bottom plate is substantially quadrangular in plan view. The upper surface of the container bottom plate 49 is inclined at the edge of the container bottom plate opening 49a. Therefore, the inner bottom surface 46 of the container 4 has a recessed basin portion 48, which is formed by the inclined surface, that is, the recessed basin wall surface 48b, and the recessed basin bottom surface 48a surrounded by the recessed basin wall surface 48b In this configuration, the electrode structure 2 is erected on the bottom surface 48a of the recessed portion. In the embodiment shown in FIG. (3A), the bottom surface 48a of the recessed portion is formed by a part of the upper surface of the electrode structure holding plate 29. As a modified form of this embodiment, for example, as shown in FIG. (5A), when the electrode structure holding plate and the container bottom plate are formed integrally, a recessed portion 48 is directly provided on the top surface of the container bottom plate.

<Fixation of the electrode structure> In order to fix the electrode structure 2 to the electrode structure holding plate 29 or the container bottom plate 49, a slit is provided in the electrode structure holding plate 29 or the container bottom plate 49, and the anode member constituting the electrode structure 2 21. The extended anode connection protrusion 25 (refer to FIG. 3) and the cathode connection protrusion 26 extended on the cathode member 22 are inserted into the slit and connected to the wire, so that the corrosion-resistant resin flows into the slit and hardens, thereby , The electrode structure 2 can be fixed to the electrode structure holding plate 29 or the container bottom plate 49 so as to ensure the water tightness between the inside of the container 4 and the circuit chamber 9.

Although the materials constituting the container side wall 4a, the container bottom plate 49, the electrode structure holding plate 29, and the electrode structure support frame 28 are not particularly limited, for example, acrylic resin or polycarbonate resin can be used very suitably. Although the materials constituting the head cover 51a, the rod 54, the power supply part 6, the circuit chamber side wall 95, and the circuit chamber bottom plate 96 are not particularly limited, for example, ABS resin or polycarbonate resin can be used very suitably.

<Change in Ozone Concentration After Generation> FIG. 8 is a graph showing the change over time of the ozone concentration of ozone water after ozone water is generated by electrolysis in the embodiment of the present invention described later. Curve C1 shows the ozone concentration when 115 mL of raw water is electrolyzed for 4 minutes to produce ozone water (Example 1), and curve C2 shows the case when 80 mL of raw water is electrolyzed for 2 minutes to produce ozone water (Example 2) The concentration of ozone. The horizontal axis is the elapsed time from the end of electrolysis. Since the ozone concentration of the ozone water is not uniform immediately after the electrolysis, and the measured concentration is unstable, the data is displayed after the elapsed time is 4 minutes. In either case, the ozone concentration decreases with the passage of time. In the case of Example 1, the ozone concentration after 20 minutes was 0.5 mg/L or more, and in the case of Example 2, the ozone concentration after 10 minutes was 0.5 mg/L or more. Example 1 corresponds to the case where the raw material water 43 is poured into the container 4 to the first water level line 43b in FIG.

<Status display during ozone water production> In one embodiment of the present invention, in the production of ozone water based on electrolysis, the main lamp 92b and the second lamp constituted by the green LED light according to the volume of the raw material water for electrolysis Either one of the first generation lamp 65b or the second generation lamp 65c is turned on to display the current state of the ozone water generating spray device 7 to the user. The main lamp 92b is a blue LED lamp installed on the upper surface of the printed circuit board 92 of the circuit chamber 9, and illuminates the raw water in the container 4 through the translucent container bottom plate 49 (refer to Figure (3A)). When the generation of ozone water ends, the main lamp 92b and the first generation lamp 65b or the second generation lamp 65c are turned off.

<Display of the effectiveness of ozone water> In one embodiment of the present invention, if the generation of ozone water based on electrolysis is completed, the blue LED light, namely the main light 92b, turns off, and the green LED light, namely the auxiliary light 92c, is replaced. That lights up. The auxiliary lamp 92c is a green LED lamp installed on the upper surface of the printed circuit board 92 of the circuit chamber 9, and irradiates the raw material water in the container 4 through the translucent container bottom plate 49 (refer to Figure (3A)). After the generation of ozone water is completed, the auxiliary lamp 92c is turned on for a predetermined period of time according to the volume of the raw material water of the power solution and then turned off. When the raw material water 43 is injected to the first water level 43b of the container 4, and the first generation button 64b is pressed to generate ozone water, the auxiliary lamp 92c lights up for the first effective time (for example, 20 minutes). When the raw material water 43 is poured up to the second water level line 43c of the container 4, and the second generation button 64c is pressed to generate ozone water, the auxiliary lamp 92c lights up for the second effective time (for example, 10 minutes). The first effective time and the second effective time are determined by considering the sterilization and deodorization effects of the sprayed ozone water. While the auxiliary lamp 92c is on, if you hold the ozone water generating sprayer 1 with your hand, pick it up from the power supply 6 and turn the lever 54 with your fingers to spray ozone water, the ozone water in the container 4 will be sprayed. The ozone concentration will not be less than 0.5mg/L, and certain sterilization and deodorization effects can be expected.

<Configuration of Control Unit> The power supply unit 6 has a control unit 63. According to the operation input from the operation button 64, the control unit 63 controls the potential of each electrode of the electrode portion 62 and the current flowing through each electrode, and controls the turning on and off of each lamp of the display lamp 65, and further, through the control electrode 62c sends a control signal to the sub-control part 92a provided on the printed circuit board 92 of the circuit chamber 9 of the container 4. The sub-control section 92a receives the control signal from the control section 63, controls the potential of the anode connection protrusion 25 and the cathode connection protrusion 26 of the electrode structure 2, and the current flowing through each connection protrusion, and controls the main lamp 92b and the sub lamp 92c The lights are turned on and off. The control part 63 has a CPU, a timer, a volatile memory and storage means, and the sub-control part 92a also has a CPU, a volatile memory and storage means.

FIG. 9 is a flowchart showing the main control flow of the control performed by the control unit 63 in the ozone water generating spray device 7 according to an embodiment of the present invention. If the power cord of the ozone water generating spray device 7 is plugged into the socket, the main control flow starts in step S1. Next, in step S2, it is checked whether it is connected to the power source (Y) or not (N), if it is connected, it proceeds to step S3, and if it is not connected, it returns to step S2. In step S3, the power supply lamp is turned on for a predetermined time (for example, 3 seconds), and it is displayed to the user that it is connected to the power supply. Next, in step S4, it is checked whether the ozone water generating sprayer 1 is seated on the power supply unit 6, if seated, go to step S5, and if not seated, return to step S4. Next, in step S5, the initial value 0 is substituted for the variable "state" of the storage state. Next, in steps S6, S7, and S8, check whether any one of the first generation button 64b, the second generation button 64c, and the power button 64a is pressed. If the first generation button 64b is pressed, then go to step S9. If the second generating button 64c is pressed, the process proceeds to step S10, if the power button 64a is pressed, the process proceeds to step S11, and if any button is not pressed, the process returns to step S4. In step S9, the value 1 is substituted for the variable "state", the first generation lamp 65b is turned on, and the first generation processing time (for example, 240 seconds) is substituted _{for the variable "t E ", and the process proceeds to step S12.} In step S10, the value 2 is substituted for the variable "state", the second generation lamp 65c is turned on, and the second generation processing time (for example, 120 seconds) is substituted _{for the variable "t E ", and the process proceeds to step S12.} In step S11, the power supply lamp 65a is turned on for a predetermined time (for example, 3 seconds), and the process proceeds to step S14 in which termination processing is performed.

In step S12, the ozone water generation process described later is performed. Next, in step S13, post-processing of ozone water production described later is performed, and the process proceeds to step S14. In step S14, a termination process described later is performed, and the process proceeds to step S15. In step S15, the main control flow ends.

10, the flow of the generation process of step S12 will be described. In the production process, the raw material water is electrolyzed for a predetermined period of time to produce ozone water. At this time, it is better to display the current status to the user in an easy-to-understand manner. In step S12s, the generation process starts. Next, in step S20, the time t of the timer is set to a zero initial value (t←0), and the timer is started. Next, in step S21, it is checked whether there is an abnormality. The so-called abnormality refers to the abnormality of the current value of the electrode part 2, the abnormality of the temperature detected by the temperature sensor, the detection of the situation where the ozone water generating sprayer 1 is not mounted on the power supply part 6, and so on. If there is an abnormality, proceed to the error termination process of step S25 described later, then proceed to step S15 and end the main control flow. The error termination process here is a process of turning off all the lights and grounding all the terminals of the connection terminal 91 after the display lamp 65 is turned into a flashing state for a predetermined time. If there is no abnormality, proceed to step S22. In step S22, it is determined whether the power button is pressed, if yes, proceed to step S26, and if yes, proceed to step S23. In step S26, the power lamp 65a is turned on for a predetermined time (for example, 3 seconds), and the process proceeds to the termination process of step S27, and then proceeds to step S15 and ends the main control flow. The termination process here is the process of turning off all the lights and grounding all the terminals of the connection terminal part 91. In step S23, the electrode structure 2 is brought into an energized state, and the main lamp 92b is brought into a lighting state, and the process proceeds to step S24. In addition, in order to bring the electrode structure 2 into the energized state, the control unit 63 sends a control signal to the sub-control unit 92a via the control electrode 62c, and the sub-control unit 92a puts the electrode structure 2 into the energized state based on the control signal. In order to turn on the main lamp 92b, the control unit 63 sends a control signal to the sub-control unit 92a via the control electrode 62c, and the sub-control unit 92a turns the main lamp 92b into the on state based on the control signal. The same is true for the auxiliary lamp 92c. In step S24, it is determined whether the time t of the timer is greater than the variable "t _E ". If yes, proceed to step S12e, end the generation process, and return to the main control flow. If so, return to step S21.

Referring to FIG. 11, the flow of the post-generation processing in step S13 will be described. In the post-production treatment, it is preferable to display to the user in an easy-to-understand manner whether the current ozone concentration of the produced ozone water is a concentration effective for sterilization and deodorization after electrolysis. In step S13s, post-generation processing starts. Next, in step S30, in the same manner as described above, the electrode structure 2 is brought into a non-energized state and the main lamp 92b is brought into an off state by the cooperation of the control unit 63 and the sub-control unit 92a. Next, in steps S31 and S32, check whether the value of the variable "state" is one of 1, 2 and neither 1 nor 2. If state=1, go to step S33, if state=2, go to In step S34, if it is neither 1 nor 2, then it is an abnormality, so proceed to step S25 to perform the aforementioned error termination processing, and then proceed to step S15 and end the main control flow. In step S33, the first generating lamp 65b is turned off, the first valid time (for example, 20 minutes) is substituted into the variable "t _G ", and the process proceeds to step S35. In step S34, the second generating lamp 65c is turned off, the second valid time (for example, 10 minutes) is substituted into the variable "t _G ", and the process proceeds to step S35. In step S35, the initial value 0 is substituted into the time t (t←0) of the timer, the timer is started, the sub lamp 92c is turned on, and the process proceeds to step S36. In step S36, it is determined whether the power button 64a is pressed. If yes, proceed to step S39, and after turning on the power lamp for a predetermined time (for example, 3 seconds), proceed to step S13e to end the post-generation process and return to the main control flow. If so, go to step S37. In step S37, it is determined whether the time t of the timer is greater than the variable "t _G ", if yes, go to step S38, if not, return to step S36. In step S38, after turning the sub-lamp 92c into the off state, the process proceeds to step S13e. In step S13e, the post-generation process is ended and the main control flow is returned.

[Example]

As shown in Fig. 5, in the present invention, the convection of the raw water in the container 4 is promoted by providing a recessed basin 48 on the inner bottom surface 46 of the container 4 and erecting the electrode structure 2 on the recessed basin bottom surface 48a. Compared with the case of the prior art without the recessed portion 48, the concentration of the generated ozone water can be increased. While keeping other conditions constant, an experiment was performed to compare the concentration of the generated ozone water in the case where the recessed basin 48 was present on the inner bottom surface 46 and the case where the recessed basin 48 was not present. In addition, with respect to the cathode opening 26o shown in FIGS. 19 and 20, an experiment was performed to compare the concentration of the generated ozone water in the case where the recessed basin 48 was present and the case where the recessed basin 48 did not exist.

<Example: The case where the recessed part is provided> As shown in Figure (18C), the anode member 21 except the anode connecting protrusion 25 has a rectangular shape. The length of the two sides of the rectangle is 14mm and 22mm, and the thickness is 1.0 The platinum anode member 21 with a thickness of 2.0 mm is wound around a linear insulating spacer 30 composed of two O-rings 30a with a thickness of 2.0 mm, and the linear insulating spacer 30 is oriented at 90° to the vertical direction The direction of the angle. The anode member 21 wound with the linear insulating spacer 30 is inserted into the cathode member 22 having a U-shaped cross-sectional shape shown in FIG. 12 to form the electrode structure 2. The cathode member 22 made of titanium with a thickness of 0.6 mm has a rectangular shape in front view except for the cathode connecting protrusion 26, and the lengths of the two sides of the rectangle are 15 mm and 23 mm. In addition, the width of the side view of the cathode member 22 is 5 mm. The cathode member 22 has a plurality of holes 27. The electrode structure 2 is erected at the center of the bottom surface 48a of the bottom portion 48 of the recess portion 48 provided on the flat inner bottom surface 46 of the container bottom plate 49 of the transparent container 4 shown in FIG. 1. The container 4 has a cylindrical shape with an inner diameter of 50mm and a height of 80mm, and the volume when the cup is full is 1.6×10 ² mL. The recessed basin 48 is rectangular in plan view, and is composed of a rectangular recessed basin bottom surface 48a and a vertical recessed basin wall surface 48b surrounding it. The length of the two sides of the rectangle is 19mm and 9mm. In addition, the height of the vertical concave basin wall surface 48b is 5 mm. Put 115 mL (embodiment 1: corresponding to the first water level 43b) or 80 mL (embodiment 2: corresponding to the second water level 43c) of the raw material water 43 into the container 4, so that the electrode structure 2 is immersed under the water surface, and then adjusted Water temperature, after confirming that the water temperature reached 20°C, a constant voltage of 12V was applied between the anode member 21 and the cathode member 22 during 240 seconds (Example 1) or 120 seconds (Example 2). electrolysis. During this period, the current value is approximately 1.0A. While keeping the water temperature at 20°C, 5 minutes after the end of electrolysis, immediately move the raw material water 43 (and ozone water (or electrolyzed water) 42) in the container 4 to a clean beaker, and use the test kit (Kyoritsu) Manufactured by the Institute of Physics and Chemistry, Ozone WAK-O3) to measure ozone concentration. The experiment was repeated 5 times, and the average value of the 5 batches of measurements was taken as the measured value of ozone concentration. The measured values of ozone concentration are 1.8 mg/L (Example 1) and 1.1 mg/L (Example 2). In addition, as the raw material water 43, commercially available mineral waters (Volvic and Kirin Co., Ltd.) that have been confirmed to have hardness and total dissolved solids (TDS) values close to the national average value of tap water are used. ).

<Comparative example: The case where the concave basin is not provided> The electrode structure 2 is constructed in the same manner as in the embodiment, and is erected in the center of the flat inner bottom surface 46 of the container bottom plate 49 of the transparent container 4 shown in FIG. 1. The inner bottom surface 46 is not provided with a recessed portion. The other configurations and conditions were exactly the same as those of Examples 1 and 2, and the production of ozone water by electrolysis and the measurement of ozone concentration were performed. Put 115mL (Comparative Example 1: Corresponding to the first water level 43b) or 80mL (Comparative Example 2: Corresponding to the second water level 43c) into the container 4 for 240 seconds (Comparative Example 1) or Electrolysis was performed during 120 seconds (Comparative Example 2), and the ozone concentration was measured 5 minutes after the end of electrolysis. A constant voltage of 12V is applied during electrolysis, and the current value is about 1.0A. The average value of 5 batches of measurements is taken as the measured value of ozone concentration. The measured values of ozone concentration are 0.6 mg/L (Comparative Example 1) and 0.4 mg/L (Comparative Example 2).

The ozone concentrations measured in Examples 1 and 2 were about 3 times that of Comparative Examples 1 and 2, respectively. In electrolysis, if the convection generated by the raw material water 43 in the container 4 is confirmed by visual inspection, it is found that the convection generated in Comparative Example 1 is significantly weaker than that in Example 1, and is limited to the vicinity of the electrode structure 2 But on a small scale. Similarly, the convection generated in Comparative Example 2 is also significantly weaker than that of Example 2, and is limited to the vicinity of the electrode structure 2 and is small in scale. It can be seen that by providing the recessed basin 48 on the inner bottom surface 46 of the container 4 and the electrode structure 2 standing on the recessed basin bottom surface 48a, the convection of the raw water in the container 4 can be promoted, and ozone can be efficiently generated by electrolysis. , And increase the ozone concentration of the generated ozone water to about 3 times.

<Example: A case where a cathode opening is provided without a recessed basin> The electrode structure 2 is configured as shown in FIG. 19, and is erected in the center of the flat inner bottom surface 46 of the container bottom plate 49 of the transparent container 4 shown in FIG. The inner bottom surface 46 is not provided with a recessed portion. Let the length (height) of the cathode opening 26o in the vertical direction be 3 mm. The other conditions and configurations were completely the same as those of Examples 1 and 2, and the production of ozone water by electrolysis and the measurement of ozone concentration were performed. Put 115mL (embodiment 3: corresponding to the first water level 43b) or 80 mL (embodiment 4: corresponding to the second water level 43c) of the raw material water 43 into the container 4, similarly for 240 seconds (embodiment 3) or Electrolysis was performed during 120 seconds (Example 4), and the ozone concentration was measured 5 minutes after the end of electrolysis. A constant voltage of 12V is applied during electrolysis, and the current value is about 1.0A. The average value of 5 batches of measurements is taken as the measured value of ozone concentration. The measured values of ozone concentration are 1.8 mg/L (Example 3) and 1.2 mg/L (Example 4).

<Example: A case where both the recessed basin part and the cathode opening part are provided> The electrode structure 2 is configured as shown in FIG. 20, and it is erected on the recessed basin 48 of the recessed basin 48 provided on the flat inner bottom surface 46 of the container bottom plate 49 of the transparent container 4 shown in Figure 1 The center of the bottom surface 48a. The length (height) in the vertical direction of the cathode opening 26o and the anode opening 25o is set to 3 mm. The other conditions were exactly the same as those of Examples 1 and 2, and the production of ozone water based on electrolysis and the measurement of ozone concentration were performed. Put 115mL (embodiment 5: corresponding to the first water level line 43b) or 80 mL (embodiment 6: corresponding to the second water level line 43c) of the raw material water 43 into the container 4, similarly for 240 seconds (embodiment 5) or Electrolysis was performed during 120 seconds (Example 6), and the ozone concentration was measured 5 minutes after the end of electrolysis. A constant voltage of 12V is applied during electrolysis, and the current value is about 1.0A. The average value of 5 batches of measurements is taken as the measured value of ozone concentration. The measured values of ozone concentration were 2.3 mg/L (Example 5) and 1.5 mg/L (Example 6).

The ozone concentrations measured in Examples 3 and 4 were approximately three times that of Comparative Examples 1 and 2, respectively. The ozone concentrations measured in Examples 5 and 6 were about 4 times that of Comparative Examples 1 and 2, respectively. In the electrolysis, if the convection generated by the raw material water 43 in the container 4 is confirmed by visual inspection, it is found that the convection generated in Comparative Example 1 is significantly weaker than that of Examples 3 and 5, and is limited to the electrode structure 2 It is small in size nearby. Similarly, the convection generated in Comparative Example 2 is also significantly weaker than that of Examples 4 and 6, and it is limited to the vicinity of the electrode structure 2 and has a small scale. It can be seen from this that the cathode opening 26o is formed between the lower portion of the cathode member 22 facing the inner bottom surface 46 of the container 4 and the inner bottom surface 46 of the container 4, or on this basis, in the container 4 The inner bottom surface 46 is provided with a concave basin 48, and the electrode structure 2 is erected on the bottom surface 48a of the concave basin. Increase to about 3~4 times.

<Verification of safety> By holding the spray mechanism 5 by hand in a space of 1m³ at a room temperature of 25°C and rotating the rod 54 to spray the ozone water generated in Example 1 with a temperature of 20°C for 10 times The space ozone concentration was measured. Perform 5 experiments and find the average value to obtain the results shown in the table below. The discharge amount of ozone water per spray is approximately 0.4 mL. Elapsed time from the end of ozone water production Space Ozone Concentration (ppm) (Before spray) 0.00250 After 0 minutes (just after the end of the generation) 0.00625 1 minute later 0.00875 15 minutes later 0.00500 30 minutes later 0.00250 From this, it can be seen that although high-concentration ozone is harmful to the human body, in the ozone water generating sprayer of the present invention, the ozone concentration is lowered and the space ozone concentration becomes a safe value of 0.01 ppm or less by making it into a mist and spraying it.

＜Verification of sterilization effect＞ After 1 minute from the end of the production, the ozone water produced in Example 1 at a temperature of 20°C was dropped on the target bacteria on the glass slide, and the number of bacteria after 15 seconds was confirmed with an optical microscope. As a result, it was confirmed that 99% of the target bacteria had been removed. The subject strain was collected from the kitchen or toilet of the sample home.

<Verification of the deodorizing effect> After 5 minutes from the end of the generation, by holding the spray mechanism 5 and rotating the rod 54 by hand, the ozone water generated in Example 1 at a temperature of 20°C is used to reduce the gaseous odorous substance Spray 10 times in a 10L bag enclosed with air at room temperature and 20°C, and measure the concentration before spraying and 10 minutes after spraying by gas chromatography, and calculate the deodorization rate. Perform 5 experiments and find the average value to obtain the results shown in the table below. In addition, isovaleric acid is one of the causes of body odor. Malodorous substance Deodorization rate after 10 minutes Isovaleric acid 84.6% acetic acid 80.0% ammonia 45.0% Isovaleric acid, acetic acid, and ammonia are responsible for the smell of toilets or shoe boxes, pets, body odors, tobacco or vehicle odors, clothes, furniture, sofas or curtains. This shows that spraying the ozone water (or electrolyzed water) produced by the ozone water production sprayer of the present invention can exert a deodorizing effect on these bad odors.
