Description

  The present invention relates to a dissolved oxygen water generating device that reforms raw water to generate a dissolved oxygen water that is neutral and rich in dissolved oxygen.

  Conventionally, an electrode composed of a cathode and an anode and an ion permeable separation membrane for partitioning both electrodes and allowing ions in water to pass freely are provided in the electrolytic cell, and raw water such as tap water is provided in the electrolytic cell. By supplying and applying a DC voltage between both electrodes, ion permeation separation is performed by utilizing the fact that cations in aqueous solution move to the cathode side and anions move to the anode side in the process of electrolyzing water. Alkaline ion water containing a large amount of cations such as magnesium ion, potassium ion and sodium ion is generated on the cathode side of the membrane, and acidic ion water containing a large amount of anions such as chloride ion and sulfate ion is generated on the anode side. There is an electrolyzed water generating apparatus (see, for example, Patent Document 1).

In this type of electrolyzed water generator, when a DC voltage is applied to the cathode (alkaline electrode) and anode (acidic electrode), the positive ions that are mineral nutrients such as calcium, magnesium, sodium, and potassium present in the raw water are Attracted to the cathode. Also, negative ions such as chlorine, sulfuric acid, and sulfur are attracted to the anode. At the same time, at the cathode, hydrogen ions H ⁺ take electrons from the cathode and become hydrogen molecules H ₂ , which escape into the air, so that hydroxide ions OH ⁻ increase and water becomes alkaline. On the other hand, at the anode, the hydroxide ions OH ⁻ give electrons to the anode and become oxygen molecules O ₂ and escape into the air, so that the hydrogen ions H ⁺ increase and the water becomes acidic. The electrolysis reaction between the cathode and the anode is represented by the following chemical equation.
Cathode: 4H ⁺ + 4e → 2H ₂
Anode: 4OH ⁻ → O ₂ + 2H ₂ O + 4e
JP 2003-390068 A

  When such an electrolyzed water generator is used, the alkaline ion water generated on the cathode side is used for various purposes such as drinking water because it contains various mineral nutrients, but the acidic water generated on the anode side Is not economical because most are thrown away.

And water exists as a water molecule group (cluster) by combining water molecules (H ₂ O) with each other with a weak force such as hydrogen bond or van der Waus (such as general tap water or spring water). Water usually forms a cluster of about 15 to 20 water molecules on average). When the raw material water is separated and produced from the alkaline ionized water and the acidic water using the electrolyzed water generating apparatus as described above, it cannot be easily separated due to the large size of the cluster, and the ionization tank is subjected to a heavy burden. The life of the generator is shortened. Furthermore, when the raw material water is generated and separated into alkaline water and acidic water, mineral components such as calcium and magnesium adhere to the electrode of the ionization tank due to electrolysis, thereby reducing the function of the electrode. is happening.

  In recent years, it has been known that so-called cluster water having a small water molecule group (cluster) improves the metabolic function of the human body, and various means for reducing the water molecule group (cluster) have been developed.

FIG. 4 is a schematic block diagram for explaining a configuration of a control device in the apparatus.

  First, the structure of the dissolved oxygen water production | generation apparatus of this example is demonstrated, referring FIGS. 1-4. As shown in FIG. 1 or FIG. 2, the dissolved oxygen water generation device 1 is schematically configured to include a water storage container 10, a water discharge cock 20, an electrode member 30, and a control device 40. In addition, the raw material water used by the following description points out common waters, such as a tap water, natural spring water (mineral water), well water, for example.

  The water storage container 10 is made of a material that is transparent so that the stored water such as glass can be seen from the outside, and the composition components of the main body of the water storage container 10 are not dissolved in the dissolved oxygen water by electrolysis performed when the raw water is reformed. It is suitable that it is formed. Moreover, the upper part of the water storage container 10 is provided with an opening 10a for pouring raw water, and is used when replenishing raw water. In addition, a detachable container lid 11 for closing the opening is provided. A vent hole 11a for releasing hydrogen gas generated when the raw water in the water storage container 10 is reformed is formed in the upper part of the container lid 11.

  The water discharge cock 20 is made of a material having excellent corrosion resistance such as plastic and stainless steel. The water discharge cock 20 is disposed at a predetermined location of the water storage container 10 and is used when the dissolved oxygen water in the water storage container 10 is discharged by operating the provided lever 21.

  In the electrode member 30, a pair of electrodes including a cathode electrode 31 and an anode electrode 32 whose surfaces are coated with platinum on a titanium electrode is disposed at a predetermined position of the central member 33. As shown in FIG. 3, the cathode electrode 31 and the anode electrode 32, when electrolyzing raw material water and reforming the water, efficiently perform electrolysis on the entire electrode. The center member 33 is formed in such a shape that one side is clockwise and the other is counterclockwise as the center and is spirally wound with a predetermined diameter, and the electrodes 31 and 32 are not in contact with each other. The electrode is disposed so that the position of the electrode is up and down with respect to the vertical direction. Further, below the electrode member 30, electrode plugs 34 for supplying a voltage to the electrodes 31 and 32 are provided corresponding to the electrodes 31 and 32, and are connected to the control device 40.

The control device 40 is a device that performs drive control of each part constituting the dissolved oxygen water generation device 1. As shown in FIG. 1, the control device 40 is provided with changeover switches 41a and 41b for switching power supply ON / OFF to the electrode member 30 and power supply ON / OFF to the illumination means 45 described later. The power is turned on / off by a predetermined operation according to the above. As shown in FIG. 4, the control device 40 includes a voltage conversion unit 42, a time measuring unit 43, a polarity switching unit 44, and an illumination unit 45.
In this example, the power supply ON / OFF to the electrode member 30 is configured by the changeover switch 41a and the power supply ON / OFF to the illumination unit 45 is performed by the changeover switch 41b. However, the arrangement position is not particularly limited.

  The voltage conversion means 42 is composed of an AC / DC converter that converts an alternating current (AC) voltage supplied from an external power source 50 such as a commercial power source into a direct current (DC) voltage, and the external power source 50 is AC / DC converted. After that, power is supplied to each part.

  The time measuring means 43 is constituted by, for example, a timer, and measures the switching time when the polarity of each electrode 31, 32 is reversed by switching the + voltage and the − voltage supplied to the cathode electrode 31 and the anode electrode 32. When the preset switching time is counted, switching information corresponding to the timing is output to the polarity switching means 44. This switching time can be arbitrarily set according to the size of the device and the use environment, but mineral components such as calcium and magnesium contained in the raw water by electrolysis at the time of water reforming are each electrode 31, In order not to adhere to the surface portion of 32, it is preferable to set within at least 10 minutes.

  The polarity switching means 44 is composed of a switch or the like, for example, and is connected to the power plug 34 of the electrode member 30. The polarity switching unit 44 switches the voltage supplied to the electrodes 31 and 32 of the electrode member 30 based on the switching information output from the time measuring unit 43 to reverse the polarity of the electrodes 31 and 32.

  The illuminating means 45 is constituted by, for example, an illumination device such as an LED, and is disposed in the vicinity of the bottom 10 b of the water storage container 10 in order to irradiate the water storage container 10 with illumination light. The illumination means 45 is used as illumination when used as a viewing display, and is turned on / off by a predetermined operation of the changeover switch 41b.

  In the dissolved oxygen water generator 1 having the above-described configuration, first, raw water is stored in the water storage container 10, and then the power is turned on by operating the changeover switch 41 a to supply power to the electrode member 30. Then, the raw water stored by supplying the direct current voltage converted from the external power supply 50 to each of the electrodes 31 and 32 of the electrode member 30 while switching the polarity at predetermined intervals is renewed, and the water discharge cock 20 is passed after a predetermined time has elapsed. Operate to discharge the modified dissolved oxygen water. Further, if necessary, the illumination switch 45 for the illumination means 45 is operated to turn on / off the illumination.

  Next, a comparative experiment between the dissolved oxygen water generated using the above-described dissolved oxygen water generator 1 and the raw water before the water reform will be described.

The contents of the experiment are: tap water is used as raw material water, and the direct current voltage converted from the external power source 50 (AC100V) to DC24V is applied to the electrode member 30 for 20 minutes to reform the raw material water to produce dissolved oxygen water. did. And compared with the produced | generated dissolved oxygen water, what put raw material water of the same quantity as dissolved oxygen water into the water storage container 10 of the same formula as what was used for the dissolved oxygen water production | generation was used as a comparison object. Moreover, the dissolved oxygen meter for measuring dissolved oxygen uses “HI98129 (combo) manufactured by Iijima Electronics Co., Ltd.”, and the pH meter uses “F-102 manufactured by Hanna Instruments Japan Co., Ltd.”. Then, the dissolved oxygen content and pH of the water stored in each container were measured.
(Raw material water)
-PH: 7.26
・ Amount of dissolved oxygen: 7.3 ppm
(Dissolved oxygen water)
-PH: 7.57
・ Amount of dissolved oxygen: 14.7ppm

  From the above experimental results, the pH of the raw water and the dissolved oxygen water of this example showed a neutral range, whereas the dissolved oxygen amount of the dissolved oxygen water was about twice that of the raw water. This is because the dissolved oxygen water generating device 1 decomposes and ionizes the water molecule group (cluster) of the raw water (formed with an average of about 5 to 7 per cluster), so that the amount of dissolved oxygen in the raw water is reduced. It is thought that it increased.

Thus, the above-described dissolved oxygen water generating apparatus 1 stores the raw water in the water storage container 10, and each electrode 31, 32 is centered on the central member 33 on the bottom 10 b of the water storage container 10, one of which is clockwise. The other is formed in a shape that is spirally wound with a predetermined diameter in the counterclockwise direction, and the electrodes 31 and 32 are electrodes with respect to the vertical direction of the central member 33 so as not to contact each other. The raw material water stored by applying a direct current voltage to the electrode member 30 arranged so that the position of the upper and lower portions of the electrode member 30 is arranged is electrolyzed and reformed.
As a result, the raw water stored in the water storage container 10 is reformed simultaneously by the electrodes 31 and 32, so that the neutral dissolved oxygen water with abundant dissolved oxygen amount and decomposed water molecule group (cluster) can be obtained. Can be generated.

  In addition, the electrode member 30 is formed in such a shape that each electrode 31 and 32 is spirally wound with a predetermined diameter, one in the clockwise direction and the other in the counterclockwise direction with the center member 33 as the center. In addition, since the electrodes 31 and 32 are arranged so that the positions of the electrodes are up and down with respect to the vertical direction of the central member 33 so that they do not contact each other, Water reforming can be performed efficiently.

  Furthermore, since the polarity of the voltage applied to the electrodes 31 and 32 of the electrode member 30 is reversed within at least 10 minutes, the effect of preventing the mineral components in the raw material water from adhering to the electrodes on the electrodes 31 and 32 is achieved. Play.

  By the way, in the dissolved oxygen water production | generation apparatus 1 mentioned above, although the shape of the water storage container 10 gave the example of the water storage container 10 of hexagonal column shape, it is not limited to this shape, According to the place and use to be used. For example, various shapes such as a cube, a rectangular parallelepiped, a polyhedron, and a sphere can be used according to the overall size and appearance balance of the apparatus.

  In addition, the electrode member 30 is not limited to the shape in which the electrodes 31 and 32 have substantially the same predetermined diameter as described above. The shape can be appropriately selected according to the size and shape of the water storage container 10 such as the size and shape of the electrode (for example, a plate shape or a rod shape) as long as the shape allows efficient electrolysis on the entire surface. Furthermore, the arrangement positions of the cathode electrode 31 and the anode electrode 32 may be reversed because the voltages supplied at predetermined intervals are reversed.

  Moreover, the dissolved oxygen water production | generation apparatus 1 mentioned above reflects illumination light in the bubble which generate | occur | produced by dissolved oxygen water and the electrolysis in the water storage container 10 by lighting / flashing the illumination means 45, and has a visual appreciation effect. It can also be used as a display for viewing. In this case, the electrode member 30 uses an electrode having a diameter smaller than that of the electrode disposed on the lower side, so that bubbles generated from the lower electrode and bubbles generated from the upper electrode are removed. Since it is mixed in a substantially annular shape and rises toward the liquid surface, the visual effect as a viewing display is further improved. In the above-described embodiment, the illumination unit 45 is described as being disposed on the bottom 10b of the water storage container 10. However, the illumination unit 45 is disposed at a location where the illumination light emitted from the illumination unit 45 is irradiated into the water storage container 10. If it is, the arrangement place of the illumination means 45 is not particularly limited.

  Further, in the above-described embodiment, the configuration in which the illumination unit 45 is provided in the control device 40 has been described. However, the present invention is not limited to this. For example, the control device 40 and the illumination unit 45 may be configured separately. it can. In this case, when a malfunction occurs in either the control device 40 or the illumination unit 45, since it is a separate body, only the failed part can be repaired, and maintenance is facilitated and convenience is improved.

As is apparent from the above description, the dissolved oxygen water produced by the present invention is not limited to use as potable water, and can be applied to a wide variety of water. For example, the chlorine odor of tap water and the ammonia odor of drainage channels and toilets can be effectively suppressed by the action of water molecules that are ionized into (clusters) and subdivided.
In addition, the abundance of dissolved oxygen makes it possible to store water for various purposes in industries such as agriculture, fishery or industry, or in buildings and general houses, such as aquariums such as goldfish and tropical fish. Aquarium for breeding animals for the purpose of appreciation and sales, aquarium and reservoir for aquaculture of seafood and algae, swimming or fire fighting pool, natural pond, lake, artificial pond, dam, etc. When it is used in this place, it is possible to prevent the water from rotting and the occurrence of water bullies.

  As mentioned above, although the best form in this invention was demonstrated, this invention is not limited with the description and drawing by this form. That is, it is a matter of course that all other forms, examples, operation techniques, and the like made by those skilled in the art based on this form are included in the scope of the present invention.
