Regarding the technical means of our inventors, several preferred embodiments are described in detail below in conjunction with the drawings, in order to provide a thorough understanding and approval of the present invention.

Hereinafter, an embodiment of the present invention will be described based on the drawings.

Fig. 1 shows a schematic configuration of the hydrogen-rich water supplier 1 of the present embodiment. The hydrogen-rich water supplier 1 is a device for storing hydrogen-rich water in which hydrogen is dissolved, and can provide hydrogen-rich water in which hydrogen is dissolved at any time. The hydrogen-rich water provided by the hydrogen-rich water supplier 1 can be used as water for drinking or cooking.

The hydrogen-rich water supplier 1 includes a water purification box 2, a water storage tank 3, and an electrolytic cell 4.

The water purification box 2 purifies the water supplied to the water storage tank 3. The water purification box 2 is configured to be detachable and replaceable with respect to the main body of the hydrogen-rich water supplier 1. The water purification box 2 is provided in the water inlet path 11 on the upstream side of the water storage tank 3. The water inlet path 11 is supplied with raw water such as tap water. The water inlet path 11 has a water inlet valve 21. The water inlet valve 21 controls the amount of water passed to the hydrogen-rich water supplier 1.

The water storage tank 3 stores the water supplied from the clean water tank 2. By appropriately controlling the opening and closing of the water inlet valve 21, the water storage volume of the water storage tank 3 is made appropriate. The water stored in the water storage tank 3 is supplied to the electrolytic tank 4 and electrolyzed.

The electrolytic tank 4 electrolyzes the water supplied from the water storage tank 3 to generate hydrogen-rich water. The electrolysis cell 4 has an electrolysis chamber 40, an anode power feeder 41, a cathode power feeder 42, and a diaphragm 43. The electrolysis chamber 40 is divided by a diaphragm 43 into an anode chamber 40A on the anode power feeder 41 side and a cathode chamber 40B on the cathode power feeder 42 side.

For the anode power feeder 41 and the cathode power feeder 42, for example, a member having a platinum plating layer formed on the surface of a mesh metal such as a metal mesh made of titanium or the like is used. The net-shaped anode power feeder 41 and the cathode power feeder 42 can spread water across the surface of the diaphragm 43 while sandwiching the diaphragm 43, thereby promoting electrolysis in the electrolysis chamber 40. The platinum coating prevents oxidation of titanium.

For the separator 43, for example, a solid polymer material composed of a fluorine-based resin having a sulfonic acid group or the like is suitably used. A plating layer composed of platinum is formed on both sides of the diaphragm 43. The plating layer of the diaphragm 43 abuts and is electrically connected to the anode power feeder 41 and the cathode power feeder 42. The diaphragm 43 passes ions generated by electrolysis. The anode power feeder 41 and the cathode power feeder 42 are electrically connected via a separator 43. In the case of applying the diaphragm 43 composed of a solid polymer material, the dissolved hydrogen concentration can be increased while the pH value of the hydrogen-rich water is increased.

Through the electrolysis in the electrolysis chamber 40, oxygen is generated in the anode chamber 40A, and hydrogen is generated in the cathode chamber 40B. In the present invention, the hydrogen gas generated in the cathode chamber 40B is dissolved in the water in the cathode chamber 40B to generate hydrogen-rich water. The hydrogen-rich water produced with electrolysis is called "electrolysis hydrogen-rich water". In addition, as an operation mode, the hydrogen-rich water supplier 1 has an “electrolyzed water production mode” that generates hydrogen-rich water through electrolysis.

The hydrogen-rich water supplier 1 of the present invention stores the hydrogen-rich water generated in the cathode chamber 40B in the storage tank 3. Then, the hydrogen-rich water stored in the water storage tank 3 can be provided according to the user's request. Therefore, the hydrogen-rich water can be provided at any time according to the user's request, and the usability of the hydrogen-rich water supplier 1 is improved.

Fig. 2 shows the electrical structure of the hydrogen-rich water supplier 1. The hydrogen-rich water supplier 1 includes: an operating unit 5 operated by a user; and a control unit 6 responsible for controlling various parts such as the water inlet valve 21, the anode feeder 41, and the cathode feeder 42.

The operation part 5 has a switch operated by a user or a touch panel for detecting electrostatic capacity (not shown in the figure). The user can set the operation mode of the hydrogen-rich water supplier 1 by operating the operation unit 5, for example. In addition, the user can set the dissolved hydrogen concentration of the hydrogen-rich water by operating the operation unit 5. When the user operates the operating portion 5, the operating portion 5 outputs a corresponding electrical signal to the control portion 6.

The control unit 6 has, for example, a CPU (Central Processing Unit) that executes various arithmetic processing, information processing, and the like, and a memory that stores programs and various information in charge of the operation of the CPU. A current detection unit 44 is provided on the current supply line between the anode feeder 41 and the control unit 6. The current detection unit 44 may be provided in the current supply line between the cathode feeder 42 and the control unit 6. The current detection unit 44 detects the electrolysis current I supplied to the anode power feeder 41 and the cathode power feeder 42 and outputs an electrical signal corresponding to the value to the control unit 6.

The control unit 6 controls the DC voltage applied to the anode power feeder 41 and the cathode power feeder 42 based on the electrical signal output from the current detection unit 44, for example. More specifically, the control unit 6 supplies power to the anode feeder 41 and the cathode so that the electrolysis current I detected by the current detection unit 44 becomes a desired value based on the dissolved hydrogen concentration set by the user or the like. The DC voltage of the body 42 performs feedback control. For example, when the electrolysis current I is too large, the control unit 6 reduces the voltage, and when the electrolysis current I is too small, the control unit 6 increases the voltage. Thereby, the electrolysis current I supplied to the anode power feeder 41 and the cathode power feeder 42 is appropriately controlled.

The control unit 6 controls the opening and closing of the water inlet valve 21 based on the electrical signal output from the water volume sensor 31. As shown in FIG. 1, the water volume sensor 31 is provided on the upper part of the water storage tank 3. The water volume sensor 31 has a floating part that floats on water. In this embodiment, the water volume sensor 31 is provided on the upper part of the water storage tank 3, and when the water storage volume of the water storage tank 3 is substantially full, the water volume sensor 31 outputs the electric signal to the control unit 6.

When the controller 6 does not receive the above-mentioned input of the electrical signal indicating that the water is in the full water state from the water volume sensor 31, it controls the water inlet valve 21 to be in an open state. As a result, water is appropriately replenished to the water storage tank 3, and the amount of water stored is maintained appropriately. In addition, the water storage amount of the water storage tank 3 in the electrolysis water production mode is represented as the first water storage amount W1.

A circulation path 12 for circulating water is provided between the water storage tank 3 and the electrolytic tank 4. A pump 22 is provided in the circulation path 12. The pump 22 drives the water in the circulation path 12 to circulate the water in the circulation path 12. The operation of the pump 22 is controlled by the control unit 6.

In the electrolyzed water production mode, the control unit 6 controls the driving voltage of the pump 22 in conjunction with the driving voltage of the pump 22 and the DC voltage applied to the anode power feeder 41 and the cathode power feeder 42. As a result, the water stored in the water storage tank 3 is circulated between the water storage tank 3 and the electrolytic tank 4, and the water supplied to the electrolytic tank 4 is electrolyzed, and the dissolved hydrogen concentration of the water stored in the water storage tank 3 is increased.

The circulation path 12 includes a flow rate adjustment valve 23 that adjusts the flow rate of water supplied to the anode chamber 40A. The flow rate adjustment valve 23 is provided in the circulation path 12a on the upstream side of the anode chamber 40A. The flow rate adjustment valve 23 restricts the flow rate of water supplied to the anode chamber 40A in the electrolytic water production mode to the first flow rate. The "first flow rate" refers to a flow rate smaller than the flow rate of water supplied to the cathode chamber 40B in the electrolysis water production mode. The flow rate of the water supplied to the anode chamber 40A is restricted by the flow rate adjustment valve 23, thereby suppressing the flow rate of the electrolyzed water flowing out of the anode chamber 40A. As a result, while effectively increasing the dissolved hydrogen concentration of the water stored in the water storage tank 3, the water utilization efficiency is also improved.

The water storage tank 3 is connected to the cooling device 7. The cooling device 7 cools the water storage tank 3 by cooling the refrigerant and supplying it to the outer wall of the water storage tank 3. The operation of the cooling device 7 is controlled by the control unit 6. As a result, the hydrogen-rich water stored in the water storage tank 3 is cooled to a desired temperature by the cooling device 7. Therefore, the cooled hydrogen-rich water can be provided at any time according to the user's request, thereby improving the usability of the hydrogen-rich water supplier 1.

The water storage tank 3 is connected to the water intake path 13. The hydrogen-rich water stored in the water storage tank 3 is taken out from the water intake path 13 and can be used by the user. A water intake valve 24 is provided in the water intake path 13. The user operates the operation unit 5 to output an electric signal from the operation unit 5 to the control unit 6, and the control unit 6 controls the opening and closing of the water intake valve 24 based on the electric signal output from the operation unit 5. Thereby, the hydrogen-rich water stored in the water storage tank 3 is taken out from the water intake 13a and can be used. A space in which the cup 100 and the like can be placed is formed under the water intake 13a, and a pan portion 13b for collecting water overflowing from the cup 100 is provided.

When the hydrogen-rich water stored in the water storage tank 3 is consumed, the control unit 6 opens the water inlet valve 21 based on the electrical signal output from the water volume sensor 31 and replenishes the water storage tank 3 from the water inlet path 11. At this time, since the dissolved hydrogen concentration of the hydrogen-rich water stored in the water storage tank 3 decreases, the control unit 6 causes the water stored in the water storage tank 3 to circulate between the water storage tank 3 and the electrolytic tank 4 again, and at the same time, in the electrolytic tank 4 Medium electrolysis, thereby increasing the concentration of dissolved hydrogen. As a result, the dissolved hydrogen concentration of the hydrogen-rich water stored in the water storage tank 3 can be maintained at a high level.

In this embodiment, under the management of the control unit 6, the hydrogen-rich water stored in the water storage tank 3 is periodically replaced. When the hydrogen-rich water is replaced, first, the hydrogen-rich water stored in the water storage tank 3 is discharged, and then new water is supplied to the water storage tank 3 from the water inlet path 11.

The water storage tank 3 is connected to a drainage path 14 for discharging hydrogen-rich water. In this embodiment, the water storage tank 3 and the drainage path 14 are connected via a part of the circulation path 12. The structure in which the water storage tank 3 and the drainage path 14 are directly connected may also be used.

A drain valve 25 is provided in the drain path 14. The drain valve 25 is controlled by the control unit 6 to perform opening and closing operations. When the drain valve 25 is opened, the hydrogen-rich water stored in the water storage tank 3 is discharged from the drain port 14a.

The tray portion 13b is connected to the drainage path 14 via a path 13c. The water collected by the tray portion 13b is discharged from the drainage path 14 via the path 13c.

Fig. 3 shows the operation of each part of the hydrogen-rich water supplier 1 and the flow of water in the electrolysis water production mode. In this figure, the water-filled area is shown with a shallow shading (hereinafter, the same applies to Figures 4 to 6).

In the electrolysis water generation mode, the water intake valve 24 and the drain valve 25 are closed, and the water inlet valve 21 is appropriately opened and closed according to the amount of water stored in the water storage tank 3. Then, the flow rate adjustment valve 23 restricts the flow rate of the water supplied to the anode chamber 40A. When a DC voltage is applied to the anode power feeder 41 and the cathode power feeder 42 in a state where the anode chamber 40A and the cathode chamber 40B are full of water, electrolysis is started in the electrolytic cell 4, and hydrogen-rich water is generated in the cathode chamber 40B.

When a driving voltage is applied to the pump 22, the water in the circulation path 12 is pressure-transported through the pump 22, the water circulates in the circulation path 12 including the water storage tank 3 and the electrolytic cell 4, and the hydrogen-rich water generated in the cathode chamber 40B is recovered To water storage tank 3.

At this time, since the flow rate of the water supplied to the anode chamber 40A is restricted by the flow rate adjusting valve 23, the dissolved oxygen concentration of the water in the anode chamber 40A rises and soon approaches saturation. Along with this, the oxygen generated by electrolysis in the anode chamber 40A is not completely dissolved in the electrolyzed water in the anode chamber 40A, but returns to the water storage tank 3 through the circulation path 12b on the downstream side of the anode chamber 40A in a gas state. The oxygen is discharged to the outside of the water storage tank 3 through the vent hole 32 provided in the upper part of the water storage tank 3. Since the internal space of the hydrogen-rich water supplier 1 is not sealed from the outside, the oxygen discharged from the water storage tank 3 is released to the atmosphere outside the hydrogen-rich water supplier 1.

The above-mentioned first flow rate is preferably set to a flow rate that supplements the water reduced by the generation of oxygen in the anode chamber 40A and the movement of ions from the anode chamber 40A to the cathode chamber 40B via the diaphragm 43. In this case, only the oxygen generated in the anode chamber 40A by the electrolysis of the permeated water flows out of the anode chamber 40A. That is, since the electrolyzed water in the anode chamber 40A does not return to the water storage tank 3, while suppressing the decrease in the dissolved hydrogen concentration of the water stored in the water storage tank 3, the water use efficiency is further improved.

As an operation mode, the hydrogen-rich water supplier 1 has a “sterilization mode” that sterilizes the water storage tank 3, the circulation path 12, the pump 22, the flow control valve 23, and the electrolytic cell 4. In the sterilization mode, the water in the water storage tank 3 or the circulation path 12 is heated and circulated. This suppresses the proliferation of bacteria and the like in each part in the hydrogen-rich water supplier 1. The sterilization mode is periodically executed under the management of the control unit 6. For example, the sterilization mode is executed in the middle of the night every day. The time zone for executing the sterilization mode and the like can be appropriately set by the user operating the operation unit 5, for example.

The water storage tank 3 is provided with a heater (heating unit) 8 for heating water in the sterilization mode. The heater 8 generates heat through Joule heat, and heats the water stored in the water storage tank 3. In addition, a heater (heating unit) 8A is provided between the water storage tank 3 and the pump 22 of the circulation path 12. The heater 8A is provided on a part of the pipe constituting the circulation path 12. The heater 8A generates heat through Joule heat, and heats the water in the circulation path 12. The heater 8 and the heater 8A are controlled by the control unit 6. Only one of the heater 8 or the heater 8A may be used as a heating unit.

Figures 4 to 6 show in time series the operation of each part of the hydrogen-rich water supplier 1 and the flow of water in the sterilization mode.

As shown in Fig. 4, in the sterilization mode, with the water inlet valve 21 and the water intake valve 24 closed, the drain valve 25 is first opened. As a result, the water stored in the water storage tank 3 is discharged from the drainage path 14, and the amount of water stored in the water storage tank 3 decreases.

Then, as shown in Fig. 5, when the water storage volume of the water storage tank 3 is smaller than the first water storage volume W1 in the electrolysis water production mode and becomes the predetermined second water storage volume W2, the control unit 6 temporarily closes the drain valve 25 to make Drainage stops. The second water storage volume W2 can be detected, for example, by installing a water volume sensor (not shown in the figure) on the side wall of the water storage tank 3.

After that, the control unit 6 heats the water stored in the water storage tank 3 and the water in the circulation path 12 through the heater 8 and the heater 8A. Thereby, hot water is generated in the water storage tank 3, and the permeated hot water in the water storage tank 3 and the circulation path 12 is sterilized, and the growth of bacteria and the like is suppressed.

Then, the control unit 6 drives the pump 22 to circulate the hot water in the circulation path 12. Thereby, hot water flows into the pump 22, the flow control valve 23, and the electrolytic cell 4, and the pump 22, the flow control valve 23, and the electrolytic cell 4 are sterilized through the hot water, and the growth of bacteria and the like is suppressed. At the same time, the circulation path 12 is sterilized through hot water throughout the week, suppressing the growth of bacteria and the like.

When the electrolytic cell 4 is sterilized, the control unit 6 controls the flow rate adjustment valve 23 so that the flow rate of the hot water supplied to the anode chamber 40A becomes a second flow rate greater than the first flow rate. Thereby, hot water is also distributed in the anode chamber 40A, the circulation path 12a on the upstream side, and the circulation path 12b on the downstream side, and the anode chamber 40A, the circulation path 12a, and the circulation path 12b are sterilized by the hot water.

The above-mentioned second flow rate is preferably set to be the same as the flow rate of the hot water supplied to the cathode chamber 40B. Thereby, the anode chamber 40A is also supplied with the same amount of hot water as the cathode chamber 40B, and the anode chamber 40A, the circulation path 12a, and the circulation path 12b can be sufficiently sterilized.

In addition, in order to obtain a sufficient sterilization effect in a short time, the temperature of the hot water is preferably 75°C or higher, for example.

In this embodiment, after the water storage volume of the water storage tank 3 is reduced to the above-mentioned second water storage volume W2, the water in the water storage tank 3 and the circulation path 12 is heated to circulate a small amount of hot water to the electrolytic cell 4, etc. Sterilize. Thereby, since the water to be heated becomes a small amount, the heating can be completed in a short time, and the electric power required for the heating can be reduced. From this viewpoint, the ratio W2/W1 of the second storage water amount W2 to the first storage water amount W1 is particularly preferably 1/10 or less, for example.

The hot water in the water storage tank 3 in the sterilization mode preferably contains water vapor S. By filling the water vapor S in the water storage tank 3, the water storage volume of the water storage tank 3 is reduced to the second water storage volume W2, and the upper region of the water storage tank 3 not soaked in hot water is sterilized by the water vapor S. For example, the water volume sensor 31, the vent hole 32, the ceiling wall 33, and the like are sterilized by permeating water vapor S.

When the sterilization of the water storage tank 3, the electrolytic tank 4, etc. is completed, the control unit 6 turns off the heater 8 and the heater 8A to end the heating. Then, as shown in FIG. 6, the water intake valve 24 and the drain valve 25 are opened, and hot water is discharged from the water storage tank 3, the circulation path 12, the electrolytic tank 4, and the like. At this time, the water intake path 13 and the drainage path 14 are sterilized by the hot water passing through the water intake path 13 and the drainage path 14. In addition, the hot water discharged from the water intake 13a is collected by the pan receiving portion 13b, and reaches the drainage path 14 through the path 13c. Thereby, the receiving part 13b and the path 13c are sterilized.

As shown in FIG. 1, in this embodiment, an ultraviolet LED (ultraviolet irradiation unit) 34 is provided on the top wall 33 of the water storage tank 3. The ultraviolet LED 34 is a light emitting diode that is controlled by the control unit 6 and irradiates ultraviolet rays. The inside of the water storage tank 3 is sterilized by the ultraviolet rays irradiated from the ultraviolet LED34. The ultraviolet LED 34 may be installed in the circulation path 12 or the electrolytic tank 4 in addition to the water storage tank 3. The ultraviolet LED 34 can be lit in the above-mentioned electrolyzed water generation mode and sterilization mode. It may be configured such that the ultraviolet LED 34 is always lit during the operation of the hydrogen-rich water supplier 1.

FIG. 7 shows a modified example of the hydrogen-rich water supplier 1, that is, the hydrogen-rich water supplier 1A. For parts of the modification shown in the figure that are not described below, the configuration of the above-mentioned hydrogen-rich water supplier 1 can be adopted. The difference between the hydrogen-rich water supplier 1A and the hydrogen-rich water supplier 1 is that it replaces the flow control valve 23 (see Figure 1) of the circulation path 12a on the upstream side of the anode chamber 40A and circulates on the downstream side of the anode chamber 40A. The path 12b is provided with a purge valve 26 and a circulation valve 27. The purge valve 26 and the circulation valve 27 are the same as the water inlet valve 21, the water intake valve 24, and the drain valve 25, and are controlled by the control unit 6 (refer to FIG. 2).

The purge valve 26 is provided between the anode chamber 40A and the circulation valve 27. The purge valve 26 separates only gas from the fluid in the circulation path 12b and guides it to the exhaust path 15. In the electrolysis water generation mode, the oxygen generated in the anode chamber 40A by the electrolysis of the permeated water is guided by the purge valve 26 and released from the exhaust path 15 to the atmosphere outside the hydrogen-rich water supplier 1A. The exhaust path 15 may be omitted, and the oxygen gas may be released into the hydrogen-rich water supplier 1A.

The circulation valve 27 controls the flow of water returning from the anode chamber 40A to the water storage tank 3 via the circulation path 12b. In the electrolyzed water production mode, the circulation valve 27 is closed, preventing the flow of electrolyzed water returning from the anode chamber 40A to the water storage tank 3. As a result, the electrolyzed water in the anode chamber 40A does not return to the water storage tank 3, thereby suppressing the decrease in the dissolved hydrogen concentration of the water stored in the water storage tank 3, and further improving the water utilization efficiency.

On the other hand, in the sterilization mode, the circulation valve 27 is opened. Thereby, hot water circulates between the water storage tank 3 and the anode chamber 40A, and the circulation path 12a, the circulation path 12b, the anode chamber 40A, the purge valve 26, and the circulation valve 27 are sterilized.

As mentioned above, the hydrogen-rich water supplier 1 of the present embodiment has been described in detail, but the present invention is not limited to the specific embodiment described above, and can be modified and implemented in various modes. That is, the hydrogen-rich water supplier 1 is provided with at least an electrolytic cell 4 that is divided into an anode chamber 40A and a cathode chamber 40B by a diaphragm 43, and generates hydrogen-rich water in the cathode chamber 40B through the water supplied by electrolysis. The hydrogen-rich water supplier 1 for hydrogen-rich water is further provided with a water storage tank 3, and it is sufficient to store the hydrogen-rich water generated in the cathode chamber 40B in the water storage tank 3.

In summary, the technical means disclosed in the present invention can effectively solve the conventional problems and achieve the expected purpose and effect. It has not been seen in the publications, has not been used publicly, and has long-term progress before the application. The patent law claims that the invention is correct.
