Description

TECHNICAL FIELD [0001] The present invention relates to an electrode structure for enhancing the hydrogen concentration of fresh water or tap water, an apparatus for producing hydrogen water using the electrode structure, and a radio-frequency water producing apparatus using the electrode structure. WATER PRODUCING APPARATUS FOR THE SAME}

TECHNICAL FIELD OF THE INVENTION The present invention relates to a hydrogen-producing plant, and more particularly, to a hydrogen-producing plant and a hydrogen-producing plant capable of enhancing the hydrogen concentration of fresh water or tap water.

Hydrogen molecules dissolved in water have a strong reducing power, which can remove active oxygen in water. This mechanism only produces water molecules and there are no other by-products. On the other hand, it is widely known that active oxygen generated during metabolism in a cell causes denaturation of proteins or genes and contributes to aging. If hydrogen molecules are abundantly dissolved in water, that is, hydrogen-rich water or water- If you can remove the active oxygen in your body, you will be able to keep your cells healthy longer. In the academic world, there have been various reports that hydrogen molecules dissolved in water have effects such as antioxidation, anti-inflammation, allergy reduction and metabolism in cells.

In general, the dissolved hydrogen concentration at room temperature can reach up to about 1.6 ppm theoretically, but it is less than 0.1 ppm in ordinary tap water or mineral water without any hydrogenation treatment. Naturally, because the concentration of dissolved hydrogen in fresh water or tap water is very low, several methods have been used to artificially strengthen the dissolved hydrogen concentration to produce hydrogen peroxide.

First, the chemical reaction method is a method in which an alkali metal stick, which generates hydrogen violently when encountered with water, is put into water to dissolve the generated hydrogen in water. Hydrogen water obtained by this method has a low hydrogen concentration and a large amount of hydrogen clusters. Therefore, the hydrogen molecules form large bubbles and are released into the atmosphere in a short time. In addition, water containing a large amount of alkali metal ions is not suitable for drinking water.

Next, the hydrogen gas injection method is a method of forcibly injecting hydrogen into water by filling high pressure hydrogen gas into purified water. This method is a good method to mass-produce hydrogenated water, but since the hydrogen dissolution state in the hydrogenated water is uneven, it is known that most hydrogen is released into the atmosphere after about half a day after opening.

On the other hand, the non-diaphragmatic electrolysis method is a method of providing hydrogen peroxide by using a phenomenon in which hydrogen ions and oxygen are enriched on the anode side and hydroxyl groups and hydrogen are enriched on the cathode side when water is electrolyzed. In order to cause electrolysis in water lacking electrolytes such as bottled water or tap water, it is necessary to apply a high voltage of several tens of volts (V) or dissolve materials such as sodium or sodium hydroxide to make electrolytic water. The electrode has a low durability because of the precipitation of salts or elution of the electrodes. Therefore, means for alternating the polarity of the two electrodes is required in order to reduce precipitation or elution phenomenon. In addition, this method is problematic in that chlorine gas is generated in the anode when tap water is used or in the case of adding water to the water to produce a strong odor, and a problem that a large amount of hypochlorous acid (HClO) Etc. To prevent this, an expensive filter, which can remove chlorine in water, may be needed.

The membrane type electrolysis method electrolyzes water in an electrolytic cell separated by an ion exchange membrane to make an acidic water rich in hydrogen ions and oxygen on the anode side and an alkaline water rich in hydroxyl and hydrogen on the cathode side, This is a method of providing water in small numbers. In addition to all the problems of the non-diaphragmatic electrolysis method, this method has a problem that the diaphragm has low durability and high cost, and that the pH of water is high for long-term drinking water.

The PEM (Polymer Electrolyte Membrane) electrolysis method is a method in which a PEM membrane is provided between a cathode electrode and a cathode electrode of a water tank, and electrolysis is performed in a single tank. While hydrogen water rich in hydroxyl and hydrogen is produced on the cathode side (That is, a proton) enriched in the positive electrode is sent to the negative electrode through the PEM membrane, and the hydroxyl group enriched on the negative electrode side is reduced by the hydrogen ion, thereby neutralizing the pH of the hydrogenated water. Although this approach solves many of the problems of conventional electrolysis, the low durability and high cost of PEM membranes and the problem of chlorine gas from the anode in the case of tap water are still present.

The hydrogen dissolution method divides the supply water into two chambers and stores it. When some feed water is electrolyzed, the gasified oxygen is released to the atmosphere, and at the same time, the gasified hydrogen is collected and the collected hydrogen is injected into the remaining supply water It is the method of manufacturing a small number. This method requires an expensive configuration such as a PEM membrane in order to generate a large amount of hydrogen at the time of electrolysis, a configuration in which hydrogen is separately collected while discharging oxygen, and a configuration in which collected hydrogen is injected into water to be dissolved Is required.

Manufacturers who market commercial hydrogenated water in a variety of ways claim that their respective dissolved hydrogen concentrations range from 0.4 to 1.6 ppm. However, the mass production of hydrogenated water is difficult to distribute cheaply while maintaining a sufficiently high dissolved hydrogen concentration. For example, because hydrogen molecules are so small, conventional plastic containers can not hold hydrogen molecules long. The aluminum can is also an overly expensive material considering the recommended intake of drinking water. On the other hand, existing devices that make small-scale, instantaneous, small-scale production of households have a high overall cost due to excessive alkaline ionization, too high pH, chlorine gas, complex construction, expensive materials and low durability there is a problem.

Accordingly, there is a need for a means for simply producing hydrogen water for a long time at a low cost.

1 is an exploded view showing a water-producing apparatus 10 according to an embodiment of the present disclosure.

1, the hydrogen-producing plant 10 may include a water tank 11, a housing 12, an electrode unit 13, and a driving circuit unit 14. As shown in FIG. According to the embodiment, the hydrogen-producing plant 10 can produce hydrogen-water by a non-membrane-type electrolysis method.

The water tank 11 is provided with a water storage space surrounded by the outer wall 111 and the bottom surface 112 so as to carry a predetermined amount of water. The bottom surface 112 of the water tank 11 is in contact with the upper surface 121 of the housing 12. The outer wall 111 and the bottom surface 112 of the water tub 11 do not cause malfunction or accidental electrical contact even when they are in contact with the metal electrode 13 and are made of a material which does not react with the produced hydrogen water, It is preferable to be made of a material.

The bottom surface 112 of the water tub 11 provides a passage for electrical connection between the drive circuit portion 14 in the housing 12 and the electrode portion 13 to be disposed in the water storage space inside the water tank 11 At least one through hole 113a, 113b, or, according to an embodiment, at least two through holes 113a, 113b.

The conductive members 134a and 134b are penetrated through the through holes 113a and 113b of the bottom surface 112 of the water tank 11 so that the inner water of the water tank 11 is filled with the conductive members 134a and 134b. An electrical connection may be formed between the electrode portion 13 disposed in the space and the driving circuit portion 14 disposed in the housing 12. [ The two conductive members 134a and 134b are electrically insulated.

Specifically, the water tray 11 can be completely separated from the housing 12, and each of the conductive members 134a and 134b can be separated from the corresponding through holes 113a and 113b of the bottom surface 112 of the water tray 11 And the first contact members 135a and 135b are engaged with the first contact members 135a and 135b at the lower portion of the bottom surface 112 of the water tank 11 through the upper surface 121 of the housing 12 And can be in electrical contact with the second contact members 122a and 122b.

More specifically, the conductive members 134a and 134b and the first contact members 135a and 135b may be coupled, for example, in a male and female thread engagement manner. 1, the first contact members 135a and 135b protrude from the bottom surface 112 of the water tub 11. However, the first contact members 135a and 135b may protrude from the bottom surface 112 of the water tub 11, The bottom surface 112 of the water tub 11 may have a shape conforming to or recessed from the lower surface of the water tub 11 so as not to damage the flatness.

The electrode unit 13 may include a cathode electrode 131 disposed to face the bottom surface of the water tub 11 and an anode electrode 132 disposed to face the cathode electrode 131. [ Specifically, the electrode unit 13 includes a cathode electrode 131 arranged horizontally and spaced apart from the bottom surface 112 of the water tank 11, for example, in the vertical direction, And the anode electrode 132 may be disposed horizontally. In other words, the anode electrode 132 is disposed on the cathode electrode 131.

When a predetermined direct current electric field is applied between the cathode electrode 131 and the anode electrode 132 in the water, the cathode electrode 131 and the anode electrode 132 are electrically connected to the cathode electrode 131 and the anode electrode 132, Lt; RTI ID = 0.0 > 132 < / RTI > In addition, the anode electrode 132 may include a plurality of voids, and the void may be formed by a mesh, a perforation, a winding, or the like. Similarly, the cathode electrode 131 may include voids implemented by meshing, perforation, winding preheating, or the like.

According to the embodiment, the anode electrode 132 is a material having a lower overvoltage to oxygen O ₂ than an overvoltage for chlorine (Cl ₂ ), and the cathode electrode 131 is lower in electrical conductivity than the anode electrode 132 It may be a material. For example, the anode electrode 132 may be a platinum or platinum coated conductive material, and the cathode electrode 131 may be a titanium material.

As a voltage is applied to the cathode electrode 131 and the anode electrode 132, aeration occurs in the water between the cathode electrode 131 and the anode electrode 132. The aeration passes through the openings of the anode electrode 132 And the hydrogen generated in the cathode electrode 131 is diluted in the water contained in the water tank 11 in accordance with the flow of the water so that the water producing apparatus 10 can remove water from fresh water or tap water Hydrogen water can be produced.

Since the cathode electrode 131 and the anode electrode 132 are arranged very close to each other, the electrical conditions under which electrolysis typically occurs in water, for example, a voltage of about 25 V and a relatively low electrical condition , Hydrogen gas can be generated in water at a direct current voltage of, for example, about 12 V and a current of about 0.5 to 1 A.

On the other hand, the following reactions may occur in the cathode electrode 131 and the anode electrode 132, respectively.

<Cathode>

2H + + 2e- &lt; / RTI &gt; H ₂

2H ₂ O + 2e - H ₂ + 2 (OH) -

<Anode>

2 (OH) - ↔ 2H + + O 2 + 4e-

2H ₂ O ↔ 4H + + O ₂ + 4e-

Since the titanium-based cathode electrode 131 is strong in corrosion resistance and relatively low in electric conductivity compared to the electrode made of platinum, precipitation of dissolved metal ions in the water can be suppressed. Low electrical conductivity of the cathode electrode 131 is to lower the current density of only the generation efficiency of hydrogen gas is also less lowering, at the place of the strong oxidizing power on the cathode electrode 132, oxygen-based active species (O-, O _2, O _3, HO ₂ , and H ₂ O ₂ ) can be suppressed. The hydrogen gas generated in a large amount around the cathode electrode 131 passes through the anode electrode 132 in an instant according to the flow of water due to the aeration due to the discharge heat generated in the cathode electrode 131 and the anode electrode 132, 11). &Lt; / RTI &gt; Therefore, the water producing apparatus 10 can reduce the time for making the ordinary water or the tap water into hydrogen water as compared with the conventional art, and the current consumption can be reduced because of the low electric conductivity of the cathode electrode 131.

Since the anode electrode 132 of the platinum material or the platinum coated conductive material has lower overvoltage to oxygen O ₂ than the overvoltage to chlorine Cl ₂ , Well oxidized and oxygen gas (O ₂ ) is produced better than chlorine gas (Cl ₂ ). Since chlorine gas (Cl ₂ ) can generate hypochlorous acid (HOCl), which is a powerful oxidant, in the periphery of the anode electrode 132, less chlorine gas (Cl ₂ ) is generated. Generating a number, even with the small number of production apparatus 10 includes a water anode electrode, so 132, suppressing the generation of chlorine gas (Cl ₂₎ in a chlorine gas hypochlorous acid (HOCl) generated from (Cl ₂₎ can be suppressed have.

On the other hand, the conventional anode electrode of iridium or iridium oxide produces chlorine gas (Cl ₂ ) well in tap water because the overvoltage for chlorine (Cl ₂ ) is lower than the overvoltage for oxygen (O ₂ ). In addition, when a cathode electrode of a platinum material having a high electrical conductivity is paired with a cathode electrode of a conventional iridium or iridium oxide, chlorine gas (Cl ₂ ) is generated more easily, making it difficult to produce water suitable for drinking.

The cathode electrode 131 and the anode electrode 132 are formed by the respective conductive members 134a and 134b and the through holes 113a and 113b formed in the bottom surface 112 of the water tank 11, And may be electrically connected to the driving circuit portion 14 inside the housing 12. [

An electrode separator 133 of nonconductive material may be interposed between the cathode electrode 131 and the anode electrode 132 to prevent electrical shorting of the two electrodes 131 and 132. The electrode separation plate 133 mainly has a function of physically separating the electrodes 131 and 132 from each other so that the electrodes 131 and 132 are not in direct contact with each other. For example, a honeycomb structure so as to occupy a space as small as possible between the electrodes 131 and 132 so as not to interfere with the flow.

The electrode separator 133 may be made of a nonconductive material of silicon, PP, or Teflon, which is resistant to acid and corrosion and is harmless to human body. The cell gap of the electrode separator 133 is about 3 to 15 mm larger than the mesh cells of the electrodes 131 and 132. The cell gap of the electrode separator 133 is about 3 to 15 mm, The thickness of the separation plate 133 may be determined to be about 0.1 mm to 5 mm. Unlike the PEM or the ion exchange membrane, the electrode separator 133 does not move charge or exchange ions, so that the cost is not increased.

The driving circuit portion 14 is connected to the cathode electrode 131 and the cathode electrode 131 via the second contact members 122a and 122b and the first contact members 135a and 135b and the conductive members 134a and 134b, A predetermined direct current electric field can be generated between the anode electrodes 132. Specifically, the driving circuit portion 14 applies a predetermined voltage and current controlled to cause electrolysis between the cathode electrode 131 and the anode electrode 132 of the electrode portion 13 to at least two conductive members 134a, 134b To the cathode electrode 131 and the anode electrode 132 via the anode electrode 131 and the anode electrode 132. [ For example, the driving circuit portion 14 can apply a voltage of about 12 V and a current of about 0.5 to 1 A between the cathode electrode 131 and the anode electrode 132. [ Under these driving conditions, the hydrogen-producing plant 10 can produce hydrogen water having a dissolved hydrogen concentration of about 800 bpm, a redox potential of about -500 mV, a pH of 7, and a residual chlorine concentration of less than an error range.

The driving circuit unit 14 internally includes a timer, a scheduler, and the like, and can drive the electrode unit 13 for a predetermined time.

For this, the cathode and anode electrodes 131 and 132 are formed with coupling holes 136a and 136b smaller than the head diameters of the bolt-type conductive members 134a and 134b and through holes 137a and 137b, respectively, have.

The head of the first bolt-type conductive member 134a passes through the through hole 137b of the anode electrode 132 and the electrode separation plate 133 but is caught by the coupling hole 136a of the cathode electrode 131, The one-bolt-type conductive member 134a can be strongly coupled to the cathode electrode 131 without touching the anode electrode 132. [ On the other hand, the head of the second bolt-type conductive member 134b does not pass through the coupling hole 136b of the anode electrode 132, but the body of the second bolt-type conductive member 134b does not touch the cathode electrode 131 The second bolt-type conductive member 134b can be insulated from the cathode electrode 131 while being strongly coupled to the anode electrode 132. As a result, the through hole 137a of the cathode electrode 131 is completely passed through.

The electrode separator 133 is preferably made of a minimum number of frames for separating and insulating the electrodes 131 and 132 and for maintaining the mechanical shape. Particularly, aeration and water flow are generated between the electrodes 131 and 132 And has a shape that can pass through. Therefore, there is no problem that the first and second bolt-type conductive members 134a and 134b are passed through the electrode separation plate 133. [

On the other hand, the bottom surface 512 of the water tank 51 is provided with at least one (at least one) water tank 51 that can provide a path for electrical connection between the wireless power receiving unit 54 and the electrode unit 53 to be disposed in the water storage space inside the water tank 51 Through holes 513a and 513b, or two or more through holes 513a and 513b according to an embodiment. The first conductive members 534a and 534b are penetrated through the through holes 513a and 513b of the bottom surface 512 of the water tank 51 so that the first conductive members 534a and 534b penetrate the water tank 51 An electrical connection may be formed between the electrode portion 53 disposed in the inner water storage space of the water tank 51 and the wireless power receiving portion 54 disposed outside the water tank 51. [ The two first conductive members 534a and 534b are electrically insulated.

Specifically, the water tank 51 can be completely separated from the housing 52, and each of the first conductive members 534a and 534b can be connected to the corresponding through hole 513a of the bottom surface 512 of the water tank 51 And 513b to be coupled with the second conductive members 535a and 535b at the lower portion of the bottom surface 512 of the water tub 51 while the second conductive members 535a and 535b are connected to the bottom surface of the water tub 51 And may be electrically connected to a wireless power receiving unit 54 fixedly attached under the wireless power receiving unit 512. More specifically, the first conductive members 534a and 534b and the second conductive members 535a and 535b may be coupled by, for example, male and female thread engagement.

The electrode unit 53 may include a cathode electrode 531 horizontally disposed so as to face the bottom surface of the water tank 51 and an anode electrode 532 horizontally disposed so as to face the cathode electrode 531. More specifically, the electrode unit 53 includes a cathode electrode 531 horizontally spaced apart from the bottom surface 512 of the water tank 51, for example, in the vertical direction, And the anode electrode 532 may be disposed horizontally. In other words, the anode electrode 532 is disposed on the cathode electrode 531.

When a predetermined direct current electric field is applied between the cathode electrode 531 and the anode electrode 532 in the water, the cathode electrode 531 and the anode electrode 532 are electrically connected to the cathode electrode 531 and the anode electrode 532, Lt; RTI ID = 0.0 &gt; 532 &lt; / RTI &gt; Further, the anode electrode 532 may include a plurality of voids, and the void may be formed by a mesh, a perforation, a winding, or the like. Similarly, the cathode electrode 531 may include voids implemented by meshing, perforation, winding preheating, or the like.

The anode electrode 532 is a material having a lower overvoltage to oxygen O ₂ than the overvoltage for chlorine Cl ₂ and the cathode electrode 531 is lower in electrical conductivity than the anode electrode 532 It may be a material. For example, the anode electrode 532 may be a platinum or platinum coated conductive material, and the cathode electrode 531 may be a titanium material.

As a voltage is applied to the cathode electrode 531 and the anode electrode 532, aeration occurs in the water between the cathode electrode 531 and the anode electrode 532. The aeration passes through the pores of the anode electrode 532 So that the hydrogen generated in the cathode electrode 531 is diluted in the water contained in the water tank 51 in accordance with the flow of the water so that the radiofrequhe water producing apparatus 50 can supply fresh water or tap water Can be produced.

Since the cathode electrode 531 and the anode electrode 532 are disposed very close to each other, the electrical conditions under which electrolysis typically takes place in water, for example, a voltage of about 25 V and a relatively low electrical condition , Hydrogen gas can be generated in water at a direct current voltage of, for example, about 12 V and a current of about 0.5 to 1 A.

When a direct current voltage of several to several tens of volts in the water is applied between two electrodes which are closely spaced at intervals of, for example, 1 mm, that is, between the anode electrode 532 and the cathode electrode 531, The local discharge heat is generated, and the water absorbing the discharge heat is locally vaporized to form bubbles. In the process of forming the bubbles formed, the liquid space in which the electric field is concentrated becomes narrower. As a result, The discharge is also caused by an electric field that is not so strong, leading to rapid destruction of the liquid dielectric. This electrochemical reaction occurring in the hydrogen-reduced water producing apparatus 50 is different from the conventional electrolysis of water in that oxygen or hydrogen is generated at each electrode due to oxidation / reduction reactions in the vicinity of distant electrodes, Which is caused by the breakdown of the insulation between the electrodes. The hydrogen-producing plant 50 can generate a large amount of hydrogen ions and hydroxyl ions at lower voltage and lower current than in the case of conventional electrolysis of water.

This phenomenon can be further enhanced if the cathode electrode 531 and the anode electrode 532 have a plurality of protrusions on their respective surfaces. The protrusions of the cathode electrode 531 and the protrusions of the anode electrode 532 are formed in the same manner as in the case where a predetermined DC electric field is applied between the cathode electrode 531 and the anode electrode 532 in the water, The insulation between the projections can be more easily broken.

On the other hand, the following reactions may occur in the cathode electrode 531 and the anode electrode 532, respectively.

<Cathode>

2H + + 2e- &lt; / RTI &gt; H ₂

2H ₂ O + 2e - H ₂ + 2 (OH) -

<Anode>

2 (OH) - ↔ 2H + + O 2 + 4e-

2H ₂ O ↔ 4H + + O ₂ + 4e-

The titanium cathode electrode 531 has a strong corrosion resistance and is relatively low in electric conductivity compared to the electrode of the platinum material, so that precipitation of metal ions dissolved in the water can be suppressed. Low electrical conductivity of the cathode electrode 531 is to lower the current density of only the generation efficiency of hydrogen gas is also less lowering, at the place of the strong oxidizing power on the anode electrode 532, oxygen-based active species (O-, O _2, O _3, HO ₂ , and H ₂ O ₂ ) can be suppressed. The hydrogen gas generated in a large amount around the cathode electrode 531 passes through the anode electrode 532 in an instant according to the flow of water due to the aeration due to the discharge heat generated in the cathode electrode 531 and the anode electrode 532, 51). &Lt; / RTI &gt; Therefore, the radio-frequency water producing apparatus 50 can reduce the time for making the ordinary water or tap water into hydrogen water as compared with the conventional techniques, and the current consumption can be reduced due to the low electric conductivity of the cathode electrode 531.

The cathode electrode 531 and the anode electrode 532 are connected to each of the two first conductive members 534a and 534b and the through holes 513a and 513b formed in the bottom surface 512 of the water tank 51 And can be electrically connected to the wireless power receiving unit 54 under the water tank 51. [

An electrode separator 533 of nonconductive material may be interposed between the cathode electrode 531 and the anode electrode 532 to prevent electrical shorting of the two electrodes 531 and 532. The electrode separator 533 mainly has a function of physically separating the electrodes 531 and 532 from each other so that the electrodes 531 and 532 are not in direct contact with each other. While the DC electric field is generated between the electrodes 531 and 532, It may have a structure that occupies a space as small as possible between the electrodes 531 and 532, for example, a honeycomb structure so as not to disturb the flow.

The electrode separator 533 may be made of silicon, PP or Teflon, which is resistant to acid and corrosion and is harmless to the human body, in the form of a net. The cell gap of the electrode separator 533 is about 3 to 15 mm larger than the mesh cells of the electrodes 531 and 532 and the electrodes 531 and 532 are formed on the electrodes 531 and 532 in accordance with specific operating conditions, The thickness of the separation plate 533 may be determined to be about 0.1 mm to 5 mm. Unlike the PEM or the ion exchange membrane, the electrode separator 533 does not increase the cost because it does not move charges or exchange ions.

The wireless power receiving unit 54 includes a power receiving coil 541 and a rectifying circuit 542. The wireless power receiving unit 54 receives the wireless power supplied by the power receiving coil 541 in the form of electromagnetic waves and controls the power receiving coil 541, The rectifying circuit 542 can rectify the AC voltage induced in the rectifying circuit 542 to generate the DC voltage. According to the embodiment, the wireless power receiving unit 54 may be configured to be integrally fixed to the electrode unit 53 and the water tub 51. [ In this case, the wireless power receiving unit 54 may be attached to the bottom surface 512 of the water tank 51.

More specifically, the wireless power receiving unit 54 receives a predetermined direct current (DC) voltage between the cathode electrode 531 and the anode electrode 532 through the first conductive members 534a and 534b and the second conductive members 535a and 535b. An electric field can be generated. More specifically, the wireless power receiving unit 54 is configured to receive a predetermined amount of radio wave power between the cathode electrode 531 and the anode electrode 532 of the electrode unit 53, A direct current electric field can be generated.

The electrode unit 53 and the wireless power receiving unit 54 are integrally coupled to each other and the electrode unit 53 and the wireless power receiving unit 54 coupled to the electrode unit 53 and the wireless power receiving unit 54 are coupled to the bottom surface 512 of the water tank 51, It can be set freely without being fixed. In this case, the wireless power receiving unit 54 may be realized by winding the electrodes 531 and 532 of the electrode unit 53 around the electrodes.

The wireless power transmission unit 55 is mounted inside the housing 52 and can supply wireless power to the wireless power reception unit 54 in the form of electromagnetic waves when aligned with the wireless power reception unit 54. [

Specifically, the radio power transmission unit 55 can transmit radio power sufficient to cause underwater plasma discharge between the cathode electrode 531 and the anode electrode 532 through the coil 551 for power transmission. For example, the wireless power transmission unit 55 may be configured such that the wireless power receiving unit 54 receiving the wireless power supplies a voltage of about 12 V and a current of about 0.5 to 1 A between the cathode electrode 531 and the anode electrode 532 It is possible to transmit the predetermined radio power through the coil 551 for power transmission. Under such driving conditions, the hydrogen-producing plant 50 can produce hydrogen water having a dissolved hydrogen concentration of about 800 ppb, an oxidation-reduction potential of about -500 mV, a pH of 7, and a residual chlorine concentration below the error range .

The wireless power supply unit 55 may further include a control unit 552 for controlling the operation of supplying wireless power. The control unit 552 can intermittently control the supply of the radio power, thereby reducing the power consumption of the radio frequency water producing apparatus 50. [ The configuration of the control unit 552 can be variously changed.

The control unit 552 controls the operation of supplying the wireless power from the wireless power supply unit 55 to the wireless power reception unit 54 only when the wireless power reception unit 54 is aligned with the wireless power supply unit 55 Can be activated. Concretely, a groove having the same or similar size as that of the wireless power receiving section 55 can be formed on the bottom surface 512 of the water tank 51, corresponding to the position of the wireless power receiving section 54. It is also possible to form a projection corresponding to the position of the wireless power supply unit 55 on the upper surface of the housing 52 and having the same or similar size as the wireless power receiving unit 54. [ For example, the push switch can be disposed inside the projection, and the push switch can be turned on when the projection of the housing 52 is aligned with the groove of the water tub 51. [ Accordingly, the control unit 552 can activate the operation of supplying the wireless power from the wireless power supply unit 55 to the wireless power receiving unit 54 only when the push switch is turned on.

According to one embodiment, the control unit 552 enables the operation of supplying wireless power only when the wireless power receiving unit 54 is aligned with the wireless power supply unit 55 while holding a predetermined amount of water in the water tank 51 can do. More specifically, the control unit 552 measures the weight of the water tank 51 and activates the operation of supplying the wireless power from the wireless power supply unit 55 to the wireless power receiving unit 54 only when the measured weight is equal to or greater than the reference value . For example, the control unit 552 may include a weight sensing sensor (e.g., Force Sensing Resistor, FSR). The FSR can change the resistance value according to the pressure with which the water tank 51 presses the housing 52, whereby the weight can be sensed.

[ On the other hand, the other head of the first conductive member 534b does not pass through the coupling hole 536b of the anode electrode 532, but the body of the first conductive member 534b does not touch the cathode electrode 531, Hole 537a of the electrode 531 so that the first conductive member 534b can be insulated from the cathode electrode 531 while strongly coupling to the anode electrode 532.
