<Embodiment>
[1. Configuration of automatic cleaning equipment]
In this embodiment, since it is suitable, it demonstrates using sodium chloride (NaCl) as an electrolyte and tap water as raw | natural water, but it is not limited to this.

As raw water, it is also possible to use various adjustment waters such as tap water, mineral water, purified water, hydrochloric acid aqueous solution or sodium hydroxide aqueous solution subjected to softening treatment. Examples of the electrolyte that can be used include various substances that dissolve in water and ionize, such as sodium hypochlorite, sodium hydrogen carbonate, hydrochloric acid, and potassium carbonate.

  FIG. 1 shows an automatic cleaning apparatus 1 as a whole, and it is assumed that various cleaning objects are cleaned.

The automatic cleaning device 1 includes a control unit 2, a bubble electrolyzed water generation device 3, and a cleaning unit 4. The control unit 2 performs overall control of the bubble electrolyzed water generating device 3 and the cleaning unit 4.

The bubble electrolyzed water generating device 3 generates electrolyzed water (hereinafter referred to as bubble electrolyzed water) containing fine bubbles (nanobubbles) on the order of nanometers and supplies it to the cleaning unit 4.

The cleaning unit 4 is, for example, a jet type cleaning machine or cleaning gun having a jet outlet for jetting bubble electrolyzed water to the object to be cleaned, a storage type washing machine or cleaning machine that stores the bubble electrolyzed water and cleans it using a water flow. Etc. are assumed. That is, the cleaning unit 4 cleans the object to be cleaned by a process such as jetting, spraying, running water, or immersion.

The control unit 2 monitors at least one of the amount of bubble electrolyzed water used in the cleaning unit 4 and the amount of bubble electrolyzed water stored or generated in the bubble electrolyzed water generating device 3, and the bubble electrolyzed water in the bubble electrolyzed water generating device 3. Control the amount of production.

  As shown in FIG. 2A, the bubbling electrolyzed water generating device 3 includes an electrolyzed water generating unit 8, a bubble generating unit 9, and a bubbling water storage unit 10. The electrolyzing unit 11 of the electrolyzed water generating unit 8 includes a cathode chamber having a cathode electrode, an anode chamber having an anode electrode, and an intermediate chamber provided between the cathode chamber and the anode chamber via a diaphragm. It has a tank-type electrolytic cell. In addition, there is no restriction | limiting in the structure of an electrolytic cell, It is possible to use the electrolytic cell of various structures, such as a 1 tank type and a 2 tank type electrolytic cell.

  When the electrolysis unit 11 is supplied with power from the power supply unit 21 and supplied with tap water as raw water and a sodium chloride aqueous solution as an electrolyte, the electrolysis unit 11 generates alkaline electrolyzed water and acidic electrolyzed water, respectively. To the unit 12. At this time, the alkaline electrolyzed water and the acidic electrolyzed water contain hydrogen gas, chlorine gas, and ozone gas generated at the electrode, respectively.

  The gas-liquid separator 12 pools alkaline electrolyzed water and acidic electrolyzed water containing the generated gas, and separates them into gas and liquid. The electrolysis unit 11 to the gas-liquid separation unit 12 preferably have a sealed structure. The gas-liquid separation unit 12 may simply stand the pooled electrolyzed water, or may perform gas-liquid separation quickly by stirring or the like.

  The gas-liquid separation unit 12 supplies generated gas (that is, hydrogen gas, chlorine gas, and ozone gas), which is a separated gas, to the bubble mixing unit 14 respectively, while separated electrolyzed water that is a separated liquid (that is, alkaline electrolyzed water). And acidic electrolyzed water) are respectively supplied to the electrolyzed water storage unit 13.

  The electrolyzed water storage unit 13 stores the separated electrolyzed water and supplies it to the bubble mixing unit 14. As a result, in the bubble mixing unit 14, the electrolyzed water stored in the electrolyzed water storage unit 13 from the electrolyzed water storage unit 13 (hereinafter referred to as stored electrolyzed water) is generated from the gas-liquid separation unit 12. Is supplied.

  The bubble mixing unit 14 mixes the stored electrolyzed water and the generated gas while swirling at high speed, thereby containing nanobubbles containing nano-order bubbles in the stored electrolyzed water and returning it to the electrolyzed water storage unit 13. In addition, the bubble mixing part 14 has two swirl tanks, mixes hydrogen gas with alkaline electrolyzed water, and mixes chlorine gas and ozone gas with acidic electrolyzed water. The configuration of this swirl tank is described in Patent Document 2, for example. And the electrolyzed water storage part 13 supplies the stored electrolyzed water to the bubbling water storage part 10 at a predetermined speed.

  Here, for example, the supply amount of the separated electrolyzed water supplied from the gas-liquid separation unit 12 and the supply amount of the stored electrolyzed water supplied to the bubble water storage unit 10 are set to 5 liters / minute, and supplied to the bubble mixing unit 14. The amount of stored electrolyzed water supplied is 20 liters / minute. In addition, the supply amount of these electrolyzed water can be freely set by changing the open area of the valve in piping, or changing the operating force of a pump.

  In this case, the stored electrolyzed water is supplied to the bubble mixing unit 14 on average four times before being supplied to the bubble water storage unit 10 and contains bubbles.

  When other conditions are the same and the supply amount of the stored electrolyzed water supplied to the bubbly water storage unit 10 is 2.5 liters / minute, the stored electrolyzed water is supplied to the bubbly water storage unit 10. In addition, the bubbles are supplied to the bubble mixing unit 14 eight times on average, and bubbles are contained.

  For example, when chlorine gas is mixed with acidic electrolyzed water, a part of the chlorine gas remains as nanobubbles in the acidic electrolyzed water, but most of the chlorine gas is separated from the acidic electrolyzed water. At this time, a part of chlorine gas is dissolved in the acidic electrolyzed water.

  When air is used as nanobubbles, if acidic electrolyzed water is supplied to the swirl tank multiple times in order to improve the nanobubble content, dissolved chlorine in the acid electrolyzed water evaporates due to neutralization reaction and high-speed swirl, and acidic electrolysis The effect as water will fade.

  However, by mixing chlorine gas with the acidic electrolyzed water, the concentration of dissolved chlorine in the acidic electrolyzed water is rather improved, so that the nanobubble content can be improved while improving the effect as the acidic electrolyzed water. Become. In addition, when it is not desired to improve the dissolved chlorine concentration, the chlorine gas concentration can be adjusted by mixing chlorine gas and air. The same applies to ozone gas.

  The same applies to alkaline electrolyzed water. By mixing hydrogen gas, the nanobubble content can be improved while improving the effect of alkaline electrolyzed water.

  As described above, the bubble electrolyzed water generating device 3 adjusts the supply amount of the stored electrolyzed water supplied to the bubble mixing unit 14 and the supply amount of the stored electrolyzed water supplied to the bubble water storage unit 10. Electrolyzed water and generated gas can be mixed over time. As a result, the bubble electrolyzed water generating device 3 can maintain or improve the effect as electrolyzed water while changing the content of nanobubbles.

  The stored electrolyzed water generated in this way is stored in the bubble water storage unit 10 as bubble electrolyzed water.

  An example of the bubble electrolyzed water generator 3 is shown in FIG. The anode electrode 22 </ b> A and the cathode electrode 22 </ b> B are connected to the power supply unit 21 and receive supply of current from the power supply unit 21. The power supply unit may supply a current from an external power supply, or may supply a current from a power supply included in the battery supply unit. In the following, only the anode side where acidic electrolyzed water is generated will be described by indicating A at the end of the symbol on the anode side and B at the end of the symbol on the cathode side. On the cathode side, the configuration is the same as that on the anode side except that alkaline electrolyzed water is generated and the generated gas is different.

  The electrolyzed water generating unit 8 includes an electrolyzing unit 11 and a gas-liquid separating unit 12 (FIG. 2A), and is connected to the fine bubble generating device 9A via pipes 24A and 25A. The pipe 24A supplies the generated gas generated by electrolysis, and the pipe 25A supplies mainly the acidic electrolyzed water to the fine bubble generating device 9A as the bubble generating unit 9.

  The fine bubble generating device 9A mixes the acidic electrolyzed water and the generated gas by, for example, high-speed turning, and includes the fine bubbles made of the generated gas in the acidic electrolyzed water to generate the bubble electrolyzed water. The fine bubble generating device 9 </ b> A is connected to the bubble water storage unit via the pipe 26 </ b> A, and stores the bubble electrolyzed water in the bubble water storage unit 10.

  In addition, in embodiment mentioned above, the case where the bubble electrolyzed water production | generation apparatus 3 produced | generated both alkaline bubble electrolyzed water and acidic bubble electrolyzed water was described. The present invention is not limited to this, and at least one of alkaline cell electrolyzed water and acid cell electrolyzed water may be generated. For example, the bubble electrolyzed water generating device 3 may generate only one of alkaline electrolyzed water and acidic electrolyzed water, and may generate bubble electrolyzed water using one of hydrogen gas, chlorine gas, and ozone gas. Alternatively, both alkaline electrolyzed water and acidic electrolyzed water may be mixed, and any one of the generated gases may be mixed to generate bubble electrolyzed water. In short, the bubble electrolyzed water generating device 3 may generate at least one bubble electrolyzed water.

[2. Example of use of bubble electrolyzed water]
Next, the usage example of bubble electrolysis water is demonstrated. The bubbling electrolyzed water has excellent oil and fat removal performance due to the effect of the electrolyzed water, and the surface tension is reduced due to the effect of fine bubbles, so that it can enter fine irregularities and effectively remove dirt. Is possible. Moreover, since the bubble electrolyzed water of this invention forms the fine bubble with the generated gas, the active ingredient in electrolyzed water elutes from the fine bubble, and the effect can be increased. Further, unlike the surfactant, rinsing is unnecessary, and the cleaning operation itself can be simplified.

  In addition, since the bubbling electrolyzed water contains ion gas, it is excellent in sterilization and deodorizing effect. Here, the sterilization and deodorization effect refers to showing at least one of the sterilization and deodorization effect. Moreover, the thing used as at least one object among disinfection and deodorization is called the disinfection deodorization object. A sterilization and deodorizing effect can be obtained simply by spraying the bubble electrolyzed water onto the sterilization and deodorization target.

  Usually, it is possible to obtain a sterilizing and deodorizing effect even with electrolyzed water, but the lifetime for maintaining the sterilizing and deodorizing effect is short, and it can be stored only for 1 to 2 weeks. On the other hand, in the cell electrolyzed water, since the active ingredient is contained as stable fine bubbles, it has a long life and can be stored in a span of several months (about 5 to 6 months) or more.

  Although it does not specifically limit as a washing | cleaning object, For example, an industrial product and the parts used for the said industrial product, a human body, an animal, a food packaging material, a cloth product, a glass product, a metal processing product, jewelry, a construction thing, a medical instrument It is preferable to be a pipe, a human body contact object with which the human body comes into contact, a rental product, a food, or the like.

  As industrial products, they are used for cleaning precision machines, substrates, semiconductors and their parts, and cleaning in manufacturing processes. When using electrolyzed water for metal cleaning applications, the electrolyte and electrolyzed water used are selected so that the oxidation state of the metal surface can be controlled. For example, when it is not desired to oxidize the metal, alkaline bubble electrolyzed water is used.

  As a human body, bubble electrolyzed water is used for washing hair, scalp, body and the like. For example, it is possible to use bubble electrolyzed water containing carbon dioxide bubbles by selecting an electrolyte that generates carbon dioxide gas as the generated gas. For example, sodium carbonate, sodium hydrogen carbonate, potassium carbonate and the like are preferably used.

  In addition, since the human skin is weakly acidic with a pH of about 4.0 to 6.5, it is possible to minimize the influence on the human body while removing dirt from the human body by making the pH of the bubble electrolyzed water weakly acidic. It becomes possible to suppress to. The pH can be controlled by adjusting the type of electrolyte, the content of the generated gas, and the concentration of the electrolyzed water. Even if the pH is adjusted by mixing acidic cell water and alkaline cell water, Good. The same applies to animals, and particularly animals such as cats that have a habit of licking their bodies can be washed without using a surfactant, so that safety can be significantly improved.

  As a food packaging material, it can be used for washing bags, plastic bottles, trays, films, tableware and the like. Since no chemicals are used for cleaning, safety can be significantly improved.

  Examples of cloth products include clothes, mats, towels and linens. In general, washing can be performed by using bubble electrolyzed water as water used in a washing machine.

  Glass products include building windows, mobile phones and smartphones, glass surfaces of liquid crystal displays, lenses, and bottles. When generating electrolyzed water, by using high-purity purified water that has passed through a filter or the like to remove chalk and minerals, air bubbles that hardly cause so-called white residue when impurities are left white when dried It is possible to generate electrolyzed water.

  Examples of metal processed products include cut products, bent products, polished products, and sheet products. It is preferable to select an electrolyte and electrolytic water to be used so that the oxidation state of the metal surface can be controlled.

  Examples of jewelry include rings, necklaces, watches, and glasses. Examples of the medical device include a wheelchair, a prosthetic leg, and a crutch.

  Construction includes public facilities, workplaces, floors and walls of ordinary households. Especially in facilities where many people come and go, such as kindergartens, nursing homes, and floors and walls of hospitals, etc., by using bubble electrolyzed water generated using an electrolyte that generates chlorine as the generated gas, at the same time as cleaning It can be sterilized and deodorized.

  Moreover, it can disinfect effectively by using for the washing | cleaning of a toilet floor, a toilet bowl, etc. It is possible to perform quick deodorization and sterilization by always providing spray-type cell electrolyzed water and spraying it on the toilet after the toilet. By mixing bubble electrolyzed water generated using an electrolyte that generates chlorine as a generated gas with a bubble water or alkaline electrolyzed water based on alkaline electrolyzed water of about 10 to 70% by weight, the odorous substances are mixed. Since both the oxidation reaction and the reduction reaction occur, the deodorizing effect is further improved.

  Examples of the pipe include various pipes such as water and sewage pipes and air ducts for houses and buildings.

  Examples of food include agricultural products such as vegetables and fruits. In addition, for foods that are easily preserved and that do not change in flavor even when immersed in water, they are immersed in bubble electrolyzed water generated using an electrolyte that generates chlorine as a generated gas for a predetermined time (for example, 1 to 120 minutes). It is preferable. When the food is immersed in the bubbling electrolyzed water, fine bubbles gather around the food and come into direct contact with each other, so that a trace amount of chlorine can be included in the food.

  As a result, it becomes possible to delay the preservation of the food and maintain the freshness of the food. For example, seafood, whole chickens and birds, such as foods that are difficult to cause body fluids to flow out due to osmotic pressure even when immersed in water due to the presence of skins and shells, and body fluids such as lard and beef tallow are hardly present in the first place For food (hereinafter referred to as body fluid non-spilled food), preservative treatment can be performed with almost no loss of flavor by applying to bubble electrolyzed water, which is preferable.

  Examples of the human body contact object with which the human body comes into contact include a bed, a sofa, a seat sheet for public transportation, and a seat sheet for a concert hall. A human body contact object with a long contact area and long contact time tends to be poor in hygiene, and is not easy to clean because of its size. By spraying the bubble electrolyzed water, a sterilizing and deodorizing effect can be obtained, and a sanitary state can be maintained.

  Examples of rental items include rental costumes used for weddings, ornaments, various accessories, and temporarily used event goods and barbecue sets. In rental products, there are many consumers who care about the hygiene condition, but the sanitary condition can be remarkably improved by the sterilization and deodorizing treatment by washing with the bubble electrolyzed water or spraying the bubble electrolyzed water.

  Moreover, it is possible to use bubble electrolysis water for a bathing use. In that case, while mainly using an electrolyte that generates carbon dioxide as the generated gas, and adding a small amount of electrolyzed water that generates chlorine as the generated gas, it is possible to obtain a heat retaining effect by the carbon dioxide gas while suppressing the growth of bacteria. It becomes possible. Moreover, by mixing the alkaline electrolyzed water-based cell electrolyzed water, it is possible to prevent the protein from adhering to the bath and to obtain a skin beautifying effect by hydrogen gas.

"Measurement and calculation method"
After washing, the reflectance at 520 nm was measured using a spectrocolorimeter, and the K / S value and the cleaning efficiency (%) were calculated from the following formula.
K / S value = {1- ^{reflectivity}} 2/2 / reflectance Washing efficiency (%) = {(K / S of the cleaning cloth) - (K / S of stained cloth after washing)} / {(stained cloth K / S)-(K / S of uncontaminated cloth)} × 100

  As shown in FIGS. 3 to 5, the cleaning power of the nano electrolyzed water 1 using the generated gas was equal to or higher than that when using the detergent, and was higher than that of the nano electrolyzed water 2 using air.

  From the above, it was confirmed that the use of the generated gas improves the cleaning effect as bubble electrolyzed water.

[3-2. Experiment of bactericidal power]
"contents of the test"
Using the bubble electrolyzed water according to the present invention, three leaves were randomly extracted from Boston lettuce (commercially available), and one was divided into four to be specimens. The sample amount was about 8 g. After the sample was lightly washed with water, it was washed with running water for 2 minutes using test water. After washing, the specimen was lightly washed with water.

  The specimen was placed in a sterilized bag and 10-fold diluted solution was added and homogenized for 1 minute. 1 ml of the finished sample solution was dispensed with a simple medium and serial dilution was performed by the pour method. The cells were cultured in an incubator at 35 ° C. for 48 hours, the number of bacteria was measured, and the average value per 3 sheets was measured.

"Test water"

Aerated acidic electrolyzed water pH3.05 Free residual chlorine concentration 40ppm

  As shown in FIG. 6, the bubbling acidic electrolyzed water had the smallest number of bacteria, and a remarkable sterilizing effect was confirmed even when compared with tap water and normal acidic electrolyzed water.

[3-3. Cleaning effect test by lard side]
A washing experiment was conducted using lard meat pieces, which are foods that do not leak body fluid, using the cell electrolyzed water according to the present invention. As the bubble electrolyzed water, alkaline electrolyzed water-based bubble electrolyzed water (about pH 11) produced using sodium chloride (NaCl) as an electrolyte was used. The main component of the fine bubbles is highly reducible hydrogen gas.

  About 1 kg of lard meat pieces were used as specimens, immersed in a water tank in which bubbling electrolyzed water was stored, and washed for 10 minutes while applying a water flow with a simple pump. The temperature in the water tank was 28 ° C. Thereafter, running water was washed with tap water, and lard meat pieces were observed. In the experiment, the same treatment was performed on five specimens.

  The lard meat pieces before washing had a light pink surface and blood spots were present in some places. Surface hair and foreign matter were also observed.

  After washing, the surface of the lard meat pieces was pure white, which is the color of lard itself, and there were almost no blood marks. Even in areas where blood stains remained slightly, the color was very light. The lard meat pieces after washing showed almost no adhesion of surface hair or foreign matter.

  That is, the surface of the lard meat piece is dissolved by the washing with the bubbling electrolyzed water, and the foreign matter is lifted and separated by the effect of the fine bubbles. In addition to protein being decomposed by high pH, it is considered that the fats and oils on the surface are emulsified and the color is whitened.

  In general, hot water is used for cleaning lard meat pieces, but the use of bubble electrolyzed water enables cleaning at room temperature, saving energy.
