Description

  The present invention relates to a functional water generator that uses hydrogen gas generated by electrolysis of water.

  Various studies have been made that the utility of hydrogen water has been effective in removing harmful active oxygen and free radicals in the living body. For example, see WO2007-21034. When such an antioxidant component is expressed in a living body, the concentration of hydrogen gas dissolved in water needs to be as high as possible.

  Conventionally, when increasing the hydrogen concentration in water by electrolysis using tap water, it is customary to increase the hydrogen concentration in water by dissolving the hydrogen gas generated from the cathode surface in the water. There are many products on the market, such as products that use a technique that dissolves hydrogen generated between plate-like electrodes such as water vessels into water.

  However, the hydrogen concentration in water when the electrolysis is performed under static conditions is 1.6 ppm at a maximum under 1 atm, and this concentration depends on the concentration of oxygen gas generated simultaneously during electrolysis. Is further reduced.

  On the other hand, as a method for efficiently dissolving hydrogen gas in water, oxygen gas generated by electrolysis is removed, and further, the hydrogen gas solubility is temporarily increased to supersaturation by giving peristalsis such as stirring water. It is known that the hydrogen gas concentration can be increased to 3 ppm or more by this method.

  As a representative example of the above method, an electrode part composed of an anode and a cathode is attached to a frame of an arbitrary shape and a separator is disposed between the anode and the cathode, and the anode and cathode of the electrode part are energized. There is known a stirring device for generating hydrogen water comprising an energization section. (Patent Document 1, hereinafter referred to as Prior Example 1)

  As another example, hydrogen-reduced water can efficiently and stably generate hydrogen bubbles, and hydrogen-reduced water that can maintain a low oxidation-reduction potential by allowing hydrogen to exist in water for a long time. A method for producing hydrogen-reduced water that can be produced in an economical manner has been proposed. (Patent Document 2, hereinafter referred to as Prior Example 2)

Japanese Patent Laid-Open No. 2005-95808 JP 2009-195882 A

  However, since the gas generated at the anode and the cathode is dissolved in water by the ordinary stirring method shown in the first example, only the desired gas cannot be dissolved in water at a high concentration. In addition, when the method of dissolving the gas by reducing the diameter by the method as shown in the preceding example 2, it is necessary to dissolve the gas after creating the swirling flow. There was a problem that it was difficult to introduce into the home easily.

  In order to solve the above-mentioned problems, the agitation-type functional water generator according to the present invention has a first electrode disposed in the center, and a cylindrical mesh structure electrode disposed as a second electrode around the first electrode. A diaphragm capable of separating only gas was disposed between the electrode and the second electrode when water was immersed. In addition, in the water electrolysis vessel having a substantially cylindrical structure, a detachable flow generator is further provided at the lower portion of the electrolysis vessel, an exhaust port is provided at the upper portion of the electrolysis vessel, and the upper portion of the second electrode portion is sealed. A special lid is provided.

  In the present invention, the functional water to be generated is hydrogen water. The first electrode may be a carbon rod and an anode.

  In the present invention, the detachable lid has a mechanism capable of being pressurized.

  In the present invention, the metal electrode is characterized in that a part of the electrode material is provided as a cylindrical center or a protruding portion directed outward.

  In the present invention, the electrolytic container is detachable from the main body.

  As described above, according to the present invention, since the diaphragm is made of a material that separates gas when immersed in water, the gas generated from the first electrode during electrolysis is discharged out of the electrolytic cell and generated from the second electrode. Only the gas can be dissolved in water, and the gas can be dissolved effectively by providing a part of the electrode material of the second electrode as a protruding portion toward the center of the cylindrical shape.

  Thereby, when the functional water to be generated is hydrogen water, it is possible to form a stirring type hydrogen water generator capable of effectively dissolving only hydrogen gas in water while having a relatively compact mechanism. it can.

[Embodiment 1]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an example showing the configuration of a stirred hydrogen water generator according to the present invention.

  The agitation-type functional water generator 101 according to the present invention has a first electrode 1 at the center and a metal electrode having a cylindrical network structure as the second electrode 2 around the first electrode 1. Between the two electrodes 2, a diaphragm 3 capable of transmitting dissolved ions in water and separating only gas when water was immersed was disposed. Further, in the water electrolysis vessel 4 having a substantially cylindrical structure, a swirl flow generating portion 5 is further provided at the lower portion of the electrolysis vessel 4, an exhaust port 6 is provided at the upper portion of the electrolysis vessel 4, and the upper portion of the second electrode portion A removable cover 7 is provided for hermetically sealing. In addition, a power supply unit 9 for applying a DC voltage is provided between the first electrode 1 and the second electrode 2.

  The operation of the electrolysis unit having the above configuration will be described. First, raw water is supplied into the electrolytic vessel 4. Ordinary tap water can be used as raw water to be used. Specifically, for example, tap water (pH = 7.6, hardness 45 mg / L) from Yao City, Osaka Prefecture can be used.

  Electrolysis is performed in the electrolytic vessel 4. As the electrode for electrolysis, for example, a carbon rod electrode having a diameter of 5 to 10 mm is disposed as the first electrode 1 in the center, and a cylindrical metal electrode having a network structure is disposed as the second electrode 2. It is installed so that the surface distance between the central carbon rod electrode and the surrounding metal electrode is about 10 to 20 mm, and electrolysis is performed.

At this time, oxygen gas and hydrogen gas are generated in the first electrode 1 by the reaction of the following formula (1) and in the second electrode 2 by the formula (2).
_{H 2 O → 1 / 2O 2} ↑ + 2H + + 2e - ··· formula (1)
2H ₂ O + 2e ⁻ → H ₂ ↑ + 2OH ⁻ Formula (2)

  At this time, a diaphragm 3 is disposed between the first electrode 1 and the second electrode 2 so that ions dissolved in water can be transmitted and gas can be separated when the water is immersed. 1 to release the oxygen gas generated by the above formula (1) from the exhaust port 6 at the upper part of the opened first electrode chamber, and only the hydrogen gas generated by the above formula (2) from the second electrode 2 To stay in.

  The carbon rod electrode, which is the first electrode 1 arranged in the center, can be electrolyzed even as a metal electrode having a titanium rod surface coated with platinum or the like. When the anode is a metal electrode, there is an advantage that oxygen gas is easily generated. On the other hand, when it is made of a carbon rod electrode, it has a merit that generation of oxygen gas due to electrolysis can be reduced at the same voltage value because the work function is larger than that of a metal electrode in addition to low cost.

  Further, the cylindrical metal electrode used as the second electrode 2 preferably has a structure that allows water to pass easily inside and outside the electrode, and may be formed by, for example, mesh forming, lath forming, punching metal forming, or the like. . Further, as the metal electrode, a metal that can easily perform electrolysis of water efficiently, for example, any one of platinum, gold, palladium, rhodium, and iridium, or an alloy thereof, or an oxide thereof is preferable. .

  In addition, the gas-separable diaphragm 3 surrounds the center electrode, and oxygen gas generated at the first electrode 1 does not leak out from the gas-separable diaphragm 3. For example, a tester-like structure or a vertically long mortar structure can be considered. Further, the shape of the material may be reinforced by attaching the diaphragm 3 to a plastic framework. The material of the diaphragm 3 includes natural fibers such as cotton, hemp, hair and silk, and hydrophilic fibers such as rayon and cupra, as well as ion exchange such as Nafion (R) (registered trademark) by DuPont. You may form with a film | membrane etc.

  When the functional water to be generated is hydrogen water, in the present invention, a swirl flow generating portion 5 is further provided in the lower part of the electrolytic vessel 4, and the hydrogen gas selectively discharged into water by the gas-separable diaphragm 3 is used. Thus, the swirl flow is generated, and the hydrogen gas can be effectively dissolved in the water using the shear flow generated by the swirl flow applied.

[Embodiment 2]
In the present embodiment, a lock mechanism 8 for applying pressure to the lid 7 of the first embodiment is additionally provided. The other parts are the same as those of the first embodiment, and the same function parts are denoted by the same reference numerals and the description thereof is omitted.
It is desirable that the lid 7 provided on the top of the electrolytic vessel 4 is detachable, and further has about 2 to 4 locking mechanisms with movable hinges as shown in FIG. This is because hydrogen gas generated at the metal electrode as the second electrode 2 can be dissolved in water in a swirling flow in a pressurized state by using such a mechanism, and a hanging mechanism is provided. Thus, it is possible to further increase the solubility of hydrogen gas. The pressurizing mechanism may be a screw screw type, but is not limited thereto as long as it is a pressurizable mechanism.

  The stirred functional water generator 102 of the present invention performs electrolysis and swirl generation in the electrolytic vessel 4. For example, a carbon rod having a diameter of 5 mm and a height of 70 mm is used as the first electrode 1 as an anode, and a platinum coated titanium electrode having a surface distance of 10 mm and a height of 70 mm is provided as a second electrode 2 as a cathode. Voltage value: When electrolysis is performed with direct current of 35 to 45 V, oxygen and hydrogen are generated on each electrode surface immediately after electrolysis. In the same manner as in the first embodiment, oxygen is selectively removed, and a swirling flow having a rotational speed of 900 to 1200 rpm is generated in the swirling flow generating unit 5 with respect to the pressurized hydrogen gas in about 2 to 3 minutes. High concentration hydrogen water having a hydrogen concentration of 3 ppm or more can be produced.

  As shown in FIG. 3, when a swirling flow is generated in the electrolytic vessel 4, the water surface is low at the center and high at the periphery due to centrifugal force, but at least one of the first electrode 1 and the second electrode 2 is stirred. It is desirable that the entire electrode is immersed in water. This is because the electrode is always immersed in water, improving the electrolysis efficiency and facilitating gas generation. In addition, one of the electrodes is always immersed in water, so that the current is shorted between the two electrodes. This is because it is considered necessary from the viewpoint of safety to prevent the occurrence of spark discharge. In addition, the white arrow in a figure shows a swirl flow.

[Embodiment 3]
In the present embodiment, a protrusion is added to the second electrode 2 of the second embodiment. The other parts are the same as those of the second embodiment, and the same function parts are denoted by the same reference numerals and the description thereof is omitted.

A removable lid 7 is provided, and the metal electrode as the second electrode 2 is further provided with a protruding portion 10 in which a part of the electrode material is directed toward the center of the cylindrical shape.

  The operation of the electrolysis part and the diaphragm part is as described in Example 1. In this embodiment, the first electrode 1 is an anode, the second electrode 2 is a cathode, and the electrode material for forming the second electrode 2 is used. A protrusion 10 is provided on a part of the protrusion. As long as the swirl flow reaches, the protrusion 10 may be outward in the radial direction of the second electrode or inward.

  This is because the water in the electrolysis vessel 4 forms a concentric flow even if a swirl flow is generated in a normal case, so that the shear flow is mainly around the swirl flow generator 5 when the surface is smooth. Only occurs in However, when the protrusions 10 are provided on a part of the electrode material forming the second electrode 2, the shear flow is also generated on the surfaces of these protrusions 10. Providing protrusions with a height of about 2 to 5 mm with respect to the flow path of the swirl flow makes it easy to generate a shear flow, and undissolved hydrogen gas bubbles with a fine particle diameter of about several μm to several tens of μm due to the shear flow. It can be dissolved as so-called microbubbles to further increase the hydrogen gas concentration in the water.

  In addition, it is desirable that the protrusion 10 on the metal electrode that is the second electrode 2 is oriented in the center direction. This is because hydrogen gas is likely to be generated around the tip of the protrusion 10 by being directed in the center direction. Further, since there is no catch when the electrode is removed and cleaned, cleaning becomes easy.

It is provided.

  In the present embodiment, a protrusion similar to the protrusion described in the third embodiment is provided as a protrusion 11 on the inner wall of the electrolytic vessel 4. When electrolysis is performed using the first electrode 1 as an anode and the second electrode 2 as a cathode, oxygen gas is generated from the first electrode and hydrogen gas is generated from the second electrode. In the present embodiment, the hydrogen gas having a fine particle size generated by the protrusions of the second electrode 2 is refined by a shear flow generated also from the protrusions 11 of the electrolytic vessel 4. Providing protrusions with a height of about 2 to 5 mm with respect to the flow path of the swirl flow makes it easy to generate a shear flow, and undissolved hydrogen gas bubbles with a fine particle diameter of about several μm to several tens of μm due to the shear flow. It can be dissolved as so-called microbubbles to further increase the hydrogen gas concentration in the water.

[Embodiment 5]

  The stirring type functional water generator 106 according to the present embodiment is a modification of the fifth embodiment. The structure is shown in FIG. Functional parts having the same functions as those in the fifth embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The agitation-type functional water generator 106 according to the present invention has a first electrode 1 at the center and a metal electrode having a cylindrical network structure as the second electrode 2 around the first electrode 1.

  In the present embodiment, unlike Embodiments 1 to 5, electrolysis is performed using the first electrode 1 as a cathode and the second electrode 2 as an anode. It is preferable to use a carbon rod for the first electrode and a platinum-coated electrode for the second electrode. Further, the electrode of the second electrode 2 is provided with a protruding portion 10 in which a part of the electrode material is directed toward the center of the cylindrical shape. In the present embodiment, the electrolytic vessel 4 is further detachable from the main body 12 after the generation of functional water is completed.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

[Summary]
In the first aspect of the present invention, a first electrode made of a carbon electrode and a second electrode made of a metal electrode are installed at the center of the electrolytic cell. The second electrode preferably has a wire mesh structure or a perforated structure so that water can pass therethrough. A partition wall is formed between the first electrode and the second electrode using a material that can transmit ions in water but not air. When electrolysis is performed using the first electrode as an anode and the second electrode as a cathode, oxygen is generated from the first electrode and hydrogen is generated from the second electrode.

  In the present invention, oxygen generated from the first electrode is prevented from being mixed with hydrogen generated from the second electrode by being blocked by a partition wall that does not allow gas to pass therethrough. Oxygen generated from the first electrode is diffused into the room from an exhaust port provided at the top of the electrode. Further, hydrogen generated from the second electrode is dissolved in water in the electrolytic vessel. Thereby, so-called hydrogen water is obtained.

  In the present invention, a stirrer (swirl flow generator) is installed at the bottom of the electrolytic vessel in order to help dissolve hydrogen. Further, the space between the partition wall and the outer shell of the electrolytic vessel is covered with a lid, so that diffusion of hydrogen from the water into the room is prevented.

  In aspect 2 of the present invention, a lock mechanism that applies pressure to the lid provided in aspect 1 is added. This increases the hydrogen concentration in the electrolytic vessel.

  In the aspect 3 of the present invention, the second electrode is provided with a plurality of protrusions. The protrusions are directed inward or outward in the radial direction of the electrolytic container, and a shearing force is generated when the swirling flow in the electrolytic container hits these protrusions. Hydrogen bubbles in water are refined by shearing force and mixed as so-called microbubbles, and can remain in water stably for a long time. This can increase the hydrogen concentration in the water.

  In aspect 4 of the present invention, in addition to the structure of aspect 3, protrusions are also provided on the inner wall of the electrolytic vessel. The protrusion has the same shape as that provided on the second electrode, and a shearing force is generated in the swirling flow along the wall of the electrolytic vessel. In both the second electrode and the electrolytic vessel wall, hydrogen bubbles in water are refined by shearing force and mixed as microbubbles, and more bubbles than in mode 3 remain in water stably for a long time. I can do it. Thereby, the hydrogen concentration in water can be made higher.

  In aspect 5 of the present invention, the electrolytic container part disclosed in aspect 3 is configured to be removable. By doing in this way, hydrogen water in which hydrogen is dissolved can be easily used for drinking.

  In aspect 6 of the present invention, the hydrogen water generator disclosed in aspect 5 is an oxygen water generator or an ozone water generator in which the polarities of the first electrode and the second electrode are switched. Using the first electrode as a cathode and the second electrode as an anode, hydrogen is generated from the first electrode, and oxygen and ozone are generated from the second electrode. Hydrogen generated from the first electrode is diffused from the exhaust port into the room.

  Oxygen or ozone generated from the second electrode is dissolved in water in the electrolytic vessel. Since ozone is more soluble in water than oxygen, so-called ozone water is obtained. This makes it possible to easily use the bactericidal power of ozone water at home for disinfecting wounds.
