Water is stored in 19 and the water is electrolyzed.

  In this main body part 10, visible light can be transmitted between the outer side of the main body part 10 and the hollow part 19 at a predetermined position above the electrode part 30 on the side surface of the cylindrical part 11 facing the hollow part 19. A window portion 11a made of a transparent material is provided, and water in the main body portion 10 can be visually recognized from the outside through the window portion 11a. Each part of the main body part 10 other than the window part 11a is an opaque material that does not transmit light, and can be given an arbitrary color tone according to demand.

  The lid body 12 is detachably attached to the cylindrical body portion 11 of the main body portion 10 to close the opening of the cylindrical body portion 11, and a new water passage hole 12 c is provided to be openable and closable so that hydrogen water is required. It can be taken out from the main body 10 in accordance with the above.

An upper lid portion 12b that is connected to be tiltable through the portion 12d and opens and closes the water passage hole 12c of the lid base portion 12a.

  At the back of the water passage hole 12c in the lid base portion 12a of the lid portion 12, a vent hole 12e that allows air to flow into the hollow portion 19 when the hydrogen water is taken out from the water passage hole 12c so that the hydrogen water flows out smoothly. Is provided. A peripheral portion surrounding the water passage hole 12c and the vent hole 12e in the lid base portion 12a has a shape that protrudes in a substantially cylindrical shape, and a part of the upper end of the upper edge that is close to the front protrudes and extends upward from the other portion, and the drinking mouth 12f Is done. In addition, a locking portion 12g that locks the convex portion of the upper lid portion 12b and holds the upper lid portion 12b in a closed state is provided at a front position opposite to the hinge portion 12d of the lid body 12.

  The drinking mouth 12f is connected to the hollow portion 19 through the water passage hole 12c, and when the main body portion 10 is sufficiently tilted with the upper lid portion 12b of the lid body 12 opened, the water in the hollow portion 19 passes through the water passage hole 12c. Further, water that is about to go outside along the drinking mouth 12f can be drunk with the mouth of the drinking mouth 12f.

  The lid body 12 is formed with a substantially cylindrical engaging portion 12h projecting downward on the lower surface side of the central portion of the lid base portion 12a. The water purifying cartridge 16 can be engaged and disengaged with the engaging portion 12h. It is a mechanism that can be attached together. When the lid base portion 12a is attached to the cylindrical portion 11, the cartridge 16 protruding into the cylindrical portion 11 is positioned above the window portion 11a of the cylindrical portion 11, and the cartridge 16 cannot be seen from the window portion 11a. The state in which hydrogen bubbles diffuse in the water of the hollow portion 19 can be seen in the entire window portion 11a, which is excellent in terms of beauty.

  The lid base portion 12a is detachably attached to the cylindrical body portion 11 while being kept in a watertight state by screwing or the like, and can be removed as necessary when the cartridge is replaced. One opening part of the cylinder part 11 opened by removing the lid base part 12a from the cylinder part 11 can be used as an input port through which water or an electrolysis auxiliary agent can be supplied into the hollow part 19. In addition, when not providing the cartridge for water purification, the structure part which can attach or detach the cover body 12 on the upper side of the cylinder part 11 is not provided, and it may be set as a simple obstruction | occlusion structure.

  The upper lid portion 12b is formed with a protruding portion 12i that is sized to be inserted inside the cylindrical protruding portion of the lid base portion 12a and protrudes downward, and holds the upper lid portion 12b in a closed state with respect to the lid base portion 12a. In this state, the protruding portion 12i is fitted to the cylindrical protruding portion of the lid base portion 12a. The sealing member 12j made of an elastic body on the surface of the projecting portion 12i is fitted with the projecting portion 12i and the cylindrical projecting portion of the lid base portion 12a so that there is no gap between the upper end of the cylindrical projecting portion of the lid base portion 12a at the periphery. The hollow portion 19 inside the main body 10 is in a watertight state from the outside by adhering to each other and closing each hole by closely adhering to each of the hole edges of the water passage hole 12c and the vent hole 12e of the lid base 12a at the tip. Isolated in

  The cartridge 16 has a large number of granular ceramic materials 17 for water purification accommodated in a hollow container having a large number of through holes and allowing water to flow between the inside and the outside without any stagnation. It is the structure attached to the 12 lid base 12a lower side so that attachment or detachment is possible. When the user tilts the main body 10 and tries to drink the water in the hollow portion 19, the water that tries to go out from the hollow portion 19 through the water passage hole 12 c passes through the cartridge 16, and the water is ceramic in the cartridge 16. By contacting with the material 17, for example, it is a mechanism that can perform water purification such as removing the odor of water. In addition, the cartridge 16 is partially submerged in a state of storing water in the hollow portion 19, and a part of the water purification function can be exerted on the water contained in the hollow portion 19.

  The total volume of the ceramic material 17 is set to be smaller than the internal volume of the cartridge 16, and the ceramic material 17 is movable within the cartridge. For this reason, when drinking the hydrogen water, as the main body 10 is tilted, the ceramic material 17 moves downward in the cartridge and concentrates in a region through which the water passes. It becomes possible to come into contact with water, and even if the ceramic material 17 is not filled with the inner volume of the cartridge 16 closely, sufficient water purification ability can be exhibited and water can be efficiently purified. Further, since each ceramic material 17 can move in the cartridge 16, the ceramic material 17 is moved and stirred every time the main body 10 is tilted, and the position of each ceramic material 17 in the cartridge 16 and the ceramic The surface position of the material 17 in contact with water is changed every time the apparatus is used, and the water purification function of the entire cartridge 16 can be maintained over a long period of time.

  The base 13 is a cylindrical body in which two bottomed cylindrical bodies having different sizes are integrally combined to have different sizes in the upper part and the lower part, and a bottom part 13a in which one bottom forms the bottom of the electrolytic cell; In this configuration, the smaller cylindrical body portion standing from the bottom surface portion 13 a is screwed and connected to the other end portion of the cylindrical body portion 11 so as to be integrated with the cylindrical body portion 11. The base portion 13 is provided with the electrode portion 30, the wall portion 40, the control circuit portion 50, and the power source portion 60. The base portion 13 is integrally combined with the cylindrical body portion 11 together with the lid body 12 to form the main body portion 10. A water-tight hollow portion 19 is generated inside. The base portion 13 can be detachably attached to the cylindrical body portion 11. In this case, maintenance of the electrode portion 30 is facilitated.

  The bottom portion of the base portion 13 is configured to be closed by disposing a bottom cover 13c. A control circuit unit 50 and a power supply unit 60 are provided in a space portion between the bottom surface portion 13a at the top of the base portion 13 and the bottom cover 13c at the bottom.

  A light emitting unit 20 is provided at the center of the bottom surface portion 13 a of the base portion 13. Further, on the side surface of the base portion 13, there are provided a power switch portion 80 and a cartridge state display portion 81 that also serve as an operation state display portion, and a charging connection terminal portion 82 that is covered with a cover when not in use.

  The light emitting portion 20 is disposed on the bottom surface portion 13 a below the hollow portion 19 in the main body portion 10, and can emit visible light toward the hollow portion 19.

  Specifically, the light emitting unit 20 includes a light transmitting window portion 21 made of a light transmitting material provided on the bottom surface portion 13 a of the base portion 13 of the main body portion 10 and a light emitting element (for example, provided below the light transmitting window portion 21). , LED) 22.

  The light emitting section 20 reflects the irradiated light to the wall section 40 provided in the electrode section 30 in a state where water is stored in the hollow section of the main body section 10, and passes through the window section 11 a to the outside of the main body section 10. Is arranged to be reachable.

  The light emitting unit 20 turns on the light emitting element 22 in a predetermined color, for example, blue under the control of the control circuit unit 50 while the electrolysis of water by energization of the electrode unit 30 is normally performed. . The user can confirm the progress of the generation of hydrogen water by electrolysis from the light from the light emitting unit 20 seen from the window 11a and the state of diffusing the hydrogen bubbles illuminated by the light.

The electrode portion 30 is arranged in a substantially cylindrical upright state above the bottom surface portion 13 a of the base portion 13 of the main body portion 10 and around the light emitting portion 20, and applies a voltage to water put in the hollow portion 19. It consists of three electrodes 31, 32, 33 that can be applied. This electrode part 30 is located on the side of the light emitting part 20 and is arranged so as not to prevent the light from the light emitting part 20 from traveling upwards through the hollow part 19.
The electrodes 31, 32, and 33 have a substantially cylindrical shape obtained by bending a metal thin plate, and are arranged along the wall portion 40 in a gap portion inside the wall portion 40 inside the main body portion 10. It is.

  These electrodes 31, 32, 33 have substantially rod-shaped connection conductors 31 a, 32 a, 33 a together with a substantially cylindrically arranged thin plate portion, and these connection conductors 31 a, 32 a, 33 a are below It is the structure which is set as the arrangement | positioning state which extended in this and penetrated the bottom face part 13a of the base 13 in the main-body part 10. FIG.

  As for these electrodes 31, 32, 33, the innermost electrode 31 and the outermost electrode 33 are used as anodes, and the intermediate electrode 32 sandwiched between them is used as a cathode. In some cases, 33 is a cathode and the intermediate electrode 32 is an anode, and the polarity can be switched by the control circuit unit 50. In the control circuit unit 50, the case where the electrodes 31 and 33 are anodes and the electrode 32 is a cathode is a forward-direction energized state, and the case where electrodes 31 and 33 are cathodes and the electrode 32 is an anode is reversed. Direction energized state. When electrolysis is performed by energizing the electrode, hydrogen is generated on the surface of the electrode serving as the cathode. The generated hydrogen bubbles rise along the surface of the electrode and are diffused into the water of the hollow portion 19 away from the electrode portion above the electrode portion 30.

  The wall portion 40 is a substantially cylindrical body in which two cylindrical bodies having different sizes are integrally combined so as to overlap each other inside and outside, and a gap for accommodating the electrode portion 30 is formed in the middle, and the base portion 13 in the main body portion 10 is formed. It is the structure arrange | positioned in the state which protrudes upwards in the bottom face part 13a upper side. The wall portion 40 is disposed in the vicinity of the electrode portion 30 so as to sandwich the electrode portion 30 between inner and outer cylindrical portions forming the wall portion 40.

  Similarly to the electrode unit 30, the wall unit 40 is located on the side of the light emitting unit 20, and is arranged so as not to prevent the light from the light emitting unit 20 from traveling above the hollow portion 19. The light from the light source 20 is allowed to travel straight upward in the hollow portion 19 while the light traveling obliquely from the light emitting portion 20 toward the wall portion 40 is one or more times on the inner peripheral surface of the wall portion 40. It will reflect and will advance the water of the hollow part 19 upwards.

  The surface of the wall 40 is a smooth surface that hardly causes diffuse reflection (irregular reflection) when light from the light emitting unit 20 hits the surface and is reflected. The wall 40 is made of a material whose surface has a high lightness color, for example, white or a plastic having a color close to it, and reduces the absorption of light from the light emitting unit 20 on the surface and reflects light. The degree to do is increased.

  The upper portion of the wall portion 40 is formed to have a shape in which the height of the upper end portion thereof is slightly larger than the height of the upper end portion of the electrode portion 30 and reaches the upper side of the electrode portion 30 so as to cover the electrode portion 30 from above. It is a configuration. And the part which covers the electrode part 30 of the upper part of the wall part 40 from the top is provided with the opening part 41 which allows the hydrogen bubble which the electrode part 30 generate | occur | produced to pass upwards.

  Thus, the wall portion 40 is provided on the electrode portion 30 so that the wall portion 40 covers the electrode portion 30 from at least the inner peripheral side, and an opening portion through which hydrogen bubbles generated in the electrode portion 30 can pass is formed. By providing a structure that allows diffusion of hydrogen bubbles into the water of the hollow portion 19 only in the upper side of the wall portion 40 above the upper end portion of the wall portion 40, hydrogen bubbles generated in the electrode portion 30 are generated from the electrode portion 30. The position where the hollow portion 19 diffuses into the water is located above the electrode portion 30 away from the light emitting portion 20, and until this position, the hydrogen bubbles are blocked by the wall portion 40 and do not leave the electrode portion 30. Since the light stays or rises only near the electrode surface, the light from the light emitting unit 20 is not hindered by the bubbles and the like, and the light appropriately illuminates the hydrogen bubbles diffusing into the water near the window 11a. Can be visible . In addition, when the wall part 40 is provided in the electrode part 30 in this way, and it can prevent that a hydrogen bubble prevents advancing of light above the light emission part 20, each electrode 31 and 32 which comprises the electrode part 30 is shown. , 33 may reach below the light emitting unit 20 so that hydrogen bubbles are generated at a position below the light emitting unit 20.

  Also, any one of the openings 41 at the top of the wall 40 is arranged so as to be located closer to the inner surface of the window 11a, and hydrogen bubbles emitted from these openings 41 diffuse into water near the window 11a. By doing so, immediately before the light traveling from the light emitting unit 20 reaches the outside through the window portion 11a, the hydrogen bubbles diffusing into water are illuminated in the vicinity of the window portion 11a, and the light illuminating the hydrogen bubbles is the shortest here. It reaches the window 11a at a distance and goes outside. As a result, the amount of hydrogen bubbles diffusing into the water while being illuminated with light can be reliably recognized through the window 11a as much as the light illuminating the hydrogen bubbles is prevented from decaying while traveling in the water.

  Furthermore, the electrode portion 30 disposed in the gap of the wall portion 40 is in a substantially cylindrical standing state, and the ratio of the arrangement region of the electrode portion 30 to the area of the cross section of the main body portion 10 is minimized. In addition, by arranging the wall 40 so as to reach the upper side of the electrode part 30, foreign matter other than water or an input necessary for drinking may be accidentally or intentionally placed in the hollow part 19 of the main body part 10. For example, even when ice or the like is charged, the charged material is placed on the upper side of the electrode unit 30 to obstruct the rise of hydrogen bubbles coming out of the opening 41 or to be in contact with the electrode unit 30 to apply force. There is nothing. In this case, the input is guided to the space portion inside the wall portion 40, but the input entering the space portion inside the wall portion 40 and reaching the bottom surface portion 13 a is a wall along the inside of the electrode portion 30. It is blocked by the portion 40 and cannot contact the electrode portion 30 from the side. Thus, by forming the cylindrical wall part 40 in the electrode part 30, the hydrogen bubble which came out from the opening part 41 comes out efficiently, and it is hard to apply unnecessary force from the wall part 40 from an input material. By adopting the structure, deformation of the electrode part 30 can be suppressed and problems can be prevented, and a situation in which the user is adversely affected can be avoided even during use such as putting an input into the hollow part 19.

  The control circuit portion 50 is disposed below the bottom surface portion 13 a of the base portion 13 of the main body portion 10 so as to be isolated from the hollow portion 19 and is electrically connected to the electrodes 31, 32, and 33 of the electrode portion 30. In addition to adjusting and controlling the energization state of the electrode unit 30, various controls including light emission control of the light emitting element 22 of the light emitting unit 20 are performed.

  Specifically, the control circuit unit 50 is attached to the inside of the base 13 as a circuit board on which each element constituting the control circuit and the like is mounted, and each of the electrodes 31, 32, 33 penetrating the bottom surface 13 a of the base 13. It is electrically connected to the connecting conductors 31a, 32a, 33a through lead wires, and the light emitting element 22 of the light emitting unit 20 is provided on the substrate.

  The control circuit unit 50 is also electrically connected to the battery constituting the power source unit 60, and controls whether or not power is supplied to the electrode unit 30 related to electrolysis and the supply level while receiving supply of necessary power. At the same time, the light emitting element 22 of the light emitting unit 20 provided on the circuit board is set to a predetermined light emitting state while the electrode unit 30 is energized, and the light emitting unit 20 performs light irradiation.

  In addition, the control circuit unit 50 includes a switch 80b of the power switch unit 80 located on the side surface of the base unit 13, a light emitting element 80c as an operation state display unit, a light emitting element 81b of the cartridge state display unit 81, and a connection for charging. Terminal portions 82 are each provided in a surface-mounted state on a circuit board.

  The power switch unit 80 is attached in a state of being embedded in the side surface of the base unit 13, and is provided on the circuit board of the control circuit unit 50 as a button unit 80 a to be pressed by the user and an arrangement in contact with the button unit 80 a. The switch 80b is of a type that changes the contact state while the button 80a is pressed, and is disposed on the back side of the button 80a. The light irradiated through the transparent button 80a reaches the outside. And a light emitting element 80c to be operated. The button unit 80a and the light emitting element 80c of the power switch unit 80 also serve as an operation state display unit that performs light emission display according to the device operation state and the error state based on the control of the control circuit unit 50. The light emitting element 80c is an RGB LED whose light emission color can be adjusted, and the control circuit unit 50 can switch the light emission color according to the operating state so that the user can grasp the state of the apparatus by the color of the light. I have to.

  The cartridge status display unit 81 is provided on a circuit board of a light transmission window portion 81a disposed integrally with the side surface of the base portion 13 and the control circuit portion 50 in the vicinity of the light transmission window portion 81a. A light emitting element 81b that allows the light irradiated through the window 81a to reach the outside, and performs light emission display according to the necessity of replacement of the cartridge 16 based on the control of the control circuit unit 50. During a period in which the cartridge 16 can be expected to normally perform the water purification function, the control circuit unit 50 causes the light emitting element 81b of the cartridge state display unit 81 to display a predetermined color (for example, green) indicating the normal state of the cartridge 16. ) Is lit.

  The connection terminal portion 82 can be exposed to the outside through an opening provided on the side surface of the base portion 13 and can be connected to a terminal portion on the charging device side such as an AC adapter. The connection terminal portion 82 is covered with a cover 82a that is detachably attached to the opening of the base portion 13 when not in use, and prevents contact with outside air or moisture. Upon receiving power supply from the charging device connected through the connection terminal unit 82, the control circuit unit 50 controls charging to the power supply unit 60. As the connection terminal portion 82, for example, a USB female connector is used, and power for charging is supplied at a voltage (5 V) corresponding to the USB standard.

  In the charging of the power supply unit 60 by the control circuit unit 50, a direct electrical connection state with the charging device is established by the connection terminal unit 82, and power is supplied for charging. However, the present invention is not limited to this, and a power receiving circuit that combines an element such as a coil that receives power by a non-contact power feeding method and a peripheral circuit is built in the base unit 13 together with the control circuit unit 50, and power feeding corresponding to the non-contact power feeding. It is also possible to adopt a configuration in which the base portion 13 is positioned in the vicinity of the apparatus for use to receive power supply related to charging, and it is possible to save the trouble of connecting a power supply cable or the like related to charging.

  The control circuit unit 50 receives power supply from the power supply unit 60 based on an operation input to the power switch unit 80 by the user, and electrolyzes water by energizing the electrodes 31, 32, 33 of the electrode unit 30. In order to generate hydrogen bubbles and generate hydrogen water, it is possible to perform various controls including energization of the electrodes 31, 32, and 33 so that the electrolysis can be appropriately performed while ensuring safety. Running.

  In the control circuit unit 50, after the start of electrolysis by energization of the electrode unit 30, the current value related to energization is monitored, and this value is preset for a predetermined time (for example, 0.2 seconds). When a predetermined current value (for example, 600 mA) that is a threshold value for current determination is reached, it is determined as an overcurrent state, the energization is stopped and the electrolysis is interrupted, and the light emitting element of the power switch unit 80 is displayed as an error display. Control is performed so that 80c blinks in a predetermined color (for example, red) for a predetermined time (for example, 10 seconds).

  Similarly, in the control circuit unit 50, while monitoring the current value related to energization after the start of electrolysis, the current value becomes a preset threshold for determining an undercurrent during a predetermined time (for example, 1 second). When it reaches a value (for example, less than 100 mA), it is determined as an undercurrent state (so-called open state) due to the absence of water around the electrode unit 30, and control is performed to stop energization and interrupt electrolysis. . Thus, by appropriately performing overcurrent detection and open detection, safety can be ensured and wasteful consumption of power can be suppressed.

  During the electrolysis, the control circuit unit 50 has the innermost electrode 31 and the outermost electrode among the three electrodes 31, 32, 33 of the electrode unit 30 in order to minimize deterioration of the electrode unit 30 due to electrolysis. The forward-direction energized state with the electrode 33 as the anode and the intermediate electrode 32 as the cathode, and the opposite, the innermost electrode 31 and the outermost electrode 33 are the cathode and the intermediate electrode 32 is the anode. Control is performed to switch the reverse direction energization state after a half time (for example, 90 seconds) of a preset electrolysis time (for example, 3 minutes) has elapsed. In addition, the control circuit unit 50 records the respective cumulative electrolysis times in the forward energization state and the reverse energization state, and at the start of energization to the electrode unit 30, the cumulative electrolysis time in the forward energization state and the reverse direction. Comparison is made with the accumulated electrolysis time in the energized state, and the energization is started by setting the energized state with the shorter accumulated electrolysis time as the initial setting, and the deterioration state of the electrode part 30 is made uniform, and the adverse effect on the electrolysis Is suppressed.

  In addition, the control circuit unit 50 prevents the start of energization of the electrode unit 30 due to an erroneous operation of the power switch unit 80 within a few seconds after the user presses the power switch unit 80 (for example, The control for energizing the electrode unit 30 is started only when the pressing operation is performed again within 3 seconds. As a result, when the power switch unit 80 is accidentally pressed due to an object touching the power switch unit 80, the electrode unit 30 is energized as it is, and the electrolysis is performed. It is possible to prevent power consumption and to ensure the maximum power supply possible period of the power supply unit 60 that is a battery.

  In addition, the control circuit unit 50 enters the low power consumption state when a predetermined time (for example, 5 seconds) elapses after the power switch unit 80 is first pressed and then the power switch unit 80 is not pressed. By shifting and stopping the power supply to each light emitting element and each part of the control circuit, the power consumption when the apparatus is not used is suppressed.

  Furthermore, the control circuit unit 50 monitors the battery voltage, and performs control to limit the electrolysis of water due to energization of the electrode unit 30 as a required charge state when the battery voltage falls below a certain set value. Specifically, when the battery voltage is lower than the set value when the electrolysis is not performed, the control circuit unit 50 detects the electrode when the user instructs the execution of the electrolysis by pressing the power switch unit 80 twice. Without starting the energization of the unit 30, as a charging prompt display, the light emitting element 80c of the power switch unit 80 is controlled to blink in a predetermined color (for example, blue) for a predetermined time (for example, 10 seconds).

  On the other hand, if the battery voltage falls below the set value during the electrolysis, the electrolysis under execution is performed normally until a predetermined time (for example, 3 minutes) elapses from the start, and then the battery is charged. As a request display, control is performed so that the light emitting element 80c of the power switch unit 80 blinks in a predetermined color (for example, blue). As a result, the user is informed that charging is required to perform electrolysis, prompts the user to perform charging, and smoothly returns to a state where the power supply 60 can supply power related to electrolysis. be able to.

  In addition, the control circuit unit 50 monitors the temperature of the power supply unit 60 that is a battery, and if this temperature deviates from a preset range (for example, −20 ° C. to 60 ° C.) as an electrolyzable range, In order to maintain the stability of the unit 60, control is performed to limit electrolysis of water due to energization of the electrode unit 30. Specifically, when the temperature is out of the electrolyzable range when electrolysis is not performed, when the user instructs to perform electrolysis by pressing the power switch unit 80 twice, the control circuit unit 50 Control that causes the light emitting element 80c of the power switch unit 80 to blink for a predetermined time (for example, 10 seconds) in a predetermined color (for example, pink) different from the above states as an error display without starting energization of the unit 30. Do.

  On the other hand, when the temperature is out of the electrolyzable range during the electrolysis, the control circuit unit 50 stops the electrolysis being performed, and displays the light emitting element 80c of the power switch unit 80 as a predetermined color (error display). For example, the control is performed to blink in pink). This informs the user that the power supply unit 60 is in a temperature state that is not suitable for performing electrolysis, and waits until the power supply unit 60 returns to an appropriate temperature range or when the temperature of the surrounding environment is the cause. Can be moved to an appropriate environment where the temperature of the power supply unit is within the electrolyzable range and can be handled using the apparatus, and the power supply unit 60 can be prevented from being deteriorated due to unreasonable use.

  In addition, the control circuit unit 50 also performs control for managing the replacement time of the cartridge 16. Specifically, the control circuit unit 50 has completed the electrolysis over a preset electrolysis time (for example, 3 minutes), or has the electrolysis been forcibly terminated by a user operation during the electrolysis time? Regardless, the number of times the electrode section 30 is energized and electrolyzed is held and recorded as the number of cartridge use counters, and updated when the electrolysis is completed or forcibly terminated. When the updated value of the number of cartridge use counters reaches a preset limit value, for example, 360 times (equivalent to the case of using 3 times a day for about 4 months), the control circuit unit 50 The light emitting element 81b of the display unit 81 is turned on in a color other than a predetermined color (for example, green) indicating a normal state (for example, red), and the user temporarily turns on the power switch until the counter number is reset. Even if the unit 80 is pressed twice to instruct the execution of electrolysis, the control circuit unit 50 performs the control to set the electrolysis prohibited state in which the energization to the electrode unit 30 is not started.

  Prior to this, the control circuit section 50 reaches a predetermined value where the updated value of the number of cartridge use counters is smaller than the limit value, for example, 318 times (360 times in about 2 weeks of use 3 times a day). In this case, that is, when the limit value is reached two weeks before the limit value), the light emitting element 81b of the cartridge state display unit 81 is changed from a lighting state of a predetermined color (for example, green) indicating a normal state to the predetermined color. Control to switch to the blinking state is performed to notify the user that the replacement time of the cartridge 16 has been reached.

  As a result, it is possible to allow the user to replace the cartridge 16 so that the cartridge 16 that has reached the end of its service life due to a decrease in the water purification ability cannot be used as it is, and the cartridge 16 that has ensured the water purification ability is used. To maintain the quality of the hydrogen water. In addition, since the user can know that the cartridge 16 has reached the replacement time by blinking display of the cartridge status display unit 81 before the electrolysis can not be performed, the user is prompted to replace the cartridge 16 and the electrolysis is performed. The user can be prevented from falling into a situation where hydrogen water cannot be obtained.

  The number of cartridge use counters in the control circuit unit 50 is equal to or more than a predetermined time (for example, 3 seconds) to the user's power switch unit 80 in a charging state in which the control circuit unit 50 controls charging of the power source unit 60. It is set to be reset when a long press operation is detected. By requiring a preparatory work such as once charging the battery to be reset, the user is not able to easily reset, and the user is prompted to replace the cartridge. After the resetting, the electrolysis can be performed, and the new electrolysis execution count starts from one.

  The power supply unit 60 supplies power to the electrode unit 30 and other operating parts under the control of the control circuit unit 50. Specifically, as the power supply unit 60, a rechargeable secondary battery such as a lithium ion battery is used.

  The power supply unit 60 is held by a holder 60a in a space between the bottom surface 13a above the base 13 and the bottom cover 13c below the base 13 in the main body 10 and in a region below the control circuit unit 50. Arranged. Note that the battery constituting the power supply unit 60 may be replaced after the bottom cover 13c is attached to and detached from the base unit 13 to enable access to the power supply unit 60. In this case, the power supply unit 60 is not limited to a rechargeable secondary battery, and may be a primary battery such as an alkaline battery or a manganese battery.

  Next, the usage state of the hydrogen water generator according to this embodiment will be described. As a premise, the ambient environment temperature of the apparatus is in a state close to room temperature included in a preset electrolyzable range, the power supply unit 60 is charged in advance, and the user operates the power switch unit 80 to operate the electrode unit 30. It shall be in the state which can be supplied with electricity. However, in the initial state of the control circuit unit 50 before the operation, the power supply to each light emitting element and each part of the control circuit is stopped while the input of the user's operation etc. to the power switch unit 80 is detectable. It is assumed that it is in a low power consumption state. Further, it is assumed that the electrodes 31, 32, and 33 of the electrode unit 30 can be electrolyzed with water without any problem when energized without deposits or deterioration. Further, in the recording by the control circuit unit 50, the cumulative electrolysis time in the forward energization state is short, and energization is performed with the forward energization state as the initial setting.

  First, the user removes the lid 12 in the main body part 10 from the cylindrical part 11, and in a state where the hollow part 19 is opened, appropriately pours raw water such as tap water into the hollow part 19 to obtain a predetermined amount of water. Add water until When water is added, the lid body 12 is attached to the cylindrical body portion 11 to integrate the main body portion 10, and the hollow portion 19 is isolated from the outside of the main body portion 10 in a watertight state.

  When the user pushes the power switch unit 80 to generate hydrogen water after putting water into the main body unit 10, the control circuit unit 50 receives the change in the conduction state of the switch 80b and performs the second operation. A transition is made to a waiting state, and the light emitting element 80c of the power switch unit 80 is turned on in a first predetermined color (for example, white).

  After the first operation of the power switch unit 80, before the first preset predetermined time (for example, 3 seconds) elapses, the user performs a second pressing operation on the power switch unit 80. Then, the control circuit unit 50 recognizes that the user has officially instructed hydrogen water generation, starts energization of the electrode unit 30, and sets the light emitting element 80c of the power switch unit 80 to a second predetermined color (for example, , Blue). In this way, energization of each electrode 31, 32, 33 of the electrode part 30 is performed, and electrolysis of water in the hollow part 19 of the main body part 10 proceeds.

  After the first operation of the power switch unit 80, if the user does not press the power switch unit 80 for the second time before the first predetermined time elapses, the control circuit unit 50 performs the first operation incorrectly. It is assumed that the next operation is awaited as a new first operation. If the user performs a new pressing operation on the power switch unit 80 before the second predetermined time (for example, 5 seconds) has elapsed from the previous operation, the control circuit unit 50 is newly changed by the user. The second pressing operation to the power switch unit 80 is awaited. On the other hand, if the user does not operate the power switch unit 80 before the second predetermined time elapses from the previous operation, the control circuit unit 50 shifts to the low power consumption state, and the power switch unit The 80 light emitting elements 80c are switched to the extinguished state, and the initial state of waiting for the first pressing operation of the user on the power switch unit 80 is restored.

  In a state in which electrolysis of water proceeds by energization of the electrode unit 30, it is publicly known on both the front and back surfaces of the intermediate electrode 32 that is a cathode and facing the inner and outer electrodes 31 and 33 that are anodes. As in the case of electrolysis of water, gaseous hydrogen is generated by reduction, a large amount of hydrogen is generated as fine bubbles on the surface of the electrode 32, and each hydrogen bubble rises along the surface of the electrode 32.

Further, in the progress of this electrolysis, the light emitting element 22 of the light emitting unit 20 is also turned on in a predetermined color (for example, blue) by the control circuit unit 50, and among the light irradiated from the light emitting unit 20, Light that travels obliquely through water through the transparent window portion 21 and travels toward the wall portion 40 is reflected one or more times on the inner peripheral surface of the wall portion 40, and the inside of the wall portion 40 in the hollow portion 19 is reflected. Proceeds upward in the water of the space.
Thus, while the light travels through the space portion inside the wall portion 40, the light from the light emitting portion 20 is not prevented from traveling by bubbles or the like, and the light reaches a region above the upper end portion of the wall portion 40.

  On the upper side of the wall portion 40, hydrogen bubbles that have risen and exit from the opening 41 at the top of the wall portion 40 are diffused into the water, and a large amount of hydrogen is dissolved in the water to generate hydrogen water. The light from the light emitting unit 20 illuminates the bubble. In particular, in the window portion 11a on the side surface of the main body portion 10 where the user can see the hollow portion 19, the light traveling from the light emitting portion 20 is close to the inner surface of the window portion 11a immediately before reaching the outside through the window portion 11a. Illuminates the hydrogen bubbles that exit from the opening 41 located in the vicinity of the window 11a and diffuse into the water. The light that illuminates the hydrogen bubbles reaches the window portion 11a with almost no attenuation at the shortest distance, goes out of the main body portion 10 through the window portion 11a, and the user sees this light.

  The user can confirm the progress of hydrogen water generation by electrolysis from the state of diffusing the hydrogen bubbles in the water illuminated by the light from the light emitting unit 20 that can be clearly seen from the window 11a.

  In a state in which electrolysis of water proceeds by energization of the electrode unit 30, the control circuit unit 50 has a length of several seconds (for example, 2 seconds) to the power switch unit 80 according to an instruction to interrupt the electrolysis by the user. It is determined whether or not a pressing operation has been performed. When a long pressing operation has been performed, the energization of the electrode unit 30 is stopped and the electrolysis is terminated.

  On the other hand, when such a long press operation has not been performed, the control circuit unit 50 continues the electrolysis, and thereafter, the elapsed time from the start of energization to the electrode unit 30 related to the electrolysis is once set in advance. When the third predetermined time (for example, 90 seconds), which is half of the electrolysis time (for example, 3 minutes), is reached, the energized state of the electrode unit 30 is set to the inner electrode 31 and the electrode 33 as the anode, The initial forward energization state with the electrode 32 as the cathode is switched to the reverse energization state with the inner and outer electrodes 31 and 33 as the cathode and the intermediate electrode 32 as the anode.

  Thereby, gaseous hydrogen is generated by reduction on each surface of the inner and outer electrodes 31, 33 that are the cathode and facing the intermediate electrode 32 that is the anode due to the reverse energization. 33, a large amount of hydrogen is generated as fine bubbles on the surface, and each hydrogen bubble rises along the surfaces of the electrodes 31, 33, but the raised hydrogen bubbles come out only from the opening 41 at the top of the wall 40. As in the forward energization state, the state in which the user can visually recognize the diffusion of the hydrogen bubbles into the water of the hollow portion 19 and the diffusion of the hydrogen bubbles in the water from the window portion 11a is maintained.

  The control circuit unit 50 switches the energization state of the electrode unit 30 from the forward direction energization state to the reverse direction energization state, and then again for a few seconds to the power switch unit 80 related to the electrolysis interruption instruction by the user (for example, It is determined whether or not a long press operation for 2 seconds has been performed. Here, when a long press operation is performed, the energization to the electrode unit 30 is stopped, and the electrolysis is finished. When the long press operation is not performed, the control circuit unit 50 continues the electrolysis, and thereafter, the elapsed time from the start of energization to the electrode unit 30 related to the electrolysis is set once. When the electrolysis time (for example, 3 minutes) is reached, the energization to the electrode unit 30 is stopped and the electrolysis is terminated.

  After the energization of the electrode unit 30 is stopped, the control circuit unit 50 switches the light emitting element 80c of the power switch unit 80 and the light emitting element 22 of the light emitting unit 20 from the on state to the off state, and to the electrode unit 30 in the previous electrolysis. The cumulative electrolysis time of each energized state is updated and recorded based on the respective durations of the forward energized state and the reverse energized state. Further, the control circuit unit 50 updates the number of cartridge use counters by one increment.

  Subsequently, the control circuit unit 50 determines whether or not the updated value of the number of cartridge use counters has reached a predetermined value (for example, 318 times) before a preset limit value, and the predetermined value Is reached, it is further determined whether or not the limit value (for example, 360 times) has been reached. If the limit value has been reached, the control circuit unit 50 causes the light emitting element of the cartridge state display unit 81 to 81b is turned on in a predetermined color (for example, red) different from the normal state, and after that, even if the user newly presses the power switch unit 80 twice to instruct execution of electrolysis, A transition is made to an electrolysis-inhibited state in which energization to the electrode unit 30 is not started. On the other hand, if the limit value has not been reached, the control circuit unit 50 causes the light emitting element 81b of the cartridge state display unit 81 to blink in a predetermined color (for example, green) indicating the normal state of the cartridge 16. The user is notified that it is time to replace the cartridge 16.

  In addition, when the updated value of the cartridge usage counter number does not reach the predetermined value, the control circuit unit 50 shifts to the low power consumption state as a normal end of the electrolysis, and performs a single electric charge. Processing related to the disassembly is completed.

  The user confirms the end of electrolysis by turning off the light emitting element 80c of the power switch unit 80 and the light emitting element 22 of the light emitting unit 20, and then locks the lid 12 in the main body 10 by the locking portion 12g at a desired timing. Is released, the upper lid portion 12b is raised, the water passage hole 12c is opened, the main body portion 10 is tilted, and the generated hydrogen water is discharged from the hollow portion 19 through the water passage hole 12c. It is possible to drink directly by putting a mouth on the drinking mouth 12f or by pouring it into another container.

  In such drinking, when the main body 10 is tilted and the hydrogen water is taken out from the hollow portion 19 through the water passage hole 12 c, the hydrogen water passes through the cartridge 16, and a large number of the hydrogen water gathered downward in the cartridge 16. By contacting the ceramic material 17, hydrogen water can be efficiently purified, and even when tap water is used as raw water, it is possible to obtain hydrogen water suitable for drinking with good water quality that does not cause discomfort due to the odor of chalk, etc. it can.

  It should be noted that when the light emitting element 81b of the cartridge state display unit 81 is in a lighting state with a predetermined color different from the normal state or in a blinking state with a predetermined color indicating the normal state, the user The body 12 is removed from the cylindrical part 11, and the cartridge 16 engaged with the lower surface side of the lid base 12a is removed and replaced with a new cartridge.

  After replacement of the cartridge 16, the user removes the cover 82 a covering the connection terminal portion 82 on the side surface of the main body, exposes the connection terminal portion 82, and connects the terminal portion on the charging device side to the connection terminal portion 82. When a charging device capable of supplying power is connected to the connection terminal unit 82, the control circuit unit 50 shifts to a charging state in which the power source unit 60 is charged, and indicates the charging state of the light emitting element 80c of the power switch unit 80. The lighting state is a predetermined color (for example, red).

  The user confirms the transition to the charging state from the lighting state of the light emitting element 80c of the power switch unit 80 in the predetermined color, and then resets the number of cartridge use counters to the power switch unit 80 in the fourth state. A long press operation over a predetermined time (for example, 3 seconds) is performed.

  In this charging state, the control circuit unit 50 records when a long press operation for a fourth predetermined time or more is performed on the power switch unit 80 according to the reset instruction of the cartridge usage counter number by the user. The number of used cartridge counters is reset to zero. Thereafter, the control circuit unit 50 returns the light emitting element 81b of the cartridge state display unit 81 to a lighting state in a predetermined color indicating a normal state, and thereafter, the user newly presses the power switch unit 80 twice. When execution of electrolysis is instructed, energization of the electrode unit 30 is started and the initial state in which electrolysis can be performed is restored. When a new electrolysis is performed, the count of the number of times of electrolysis is started from one.

  As described above, the hydrogen water generating apparatus according to the present embodiment includes the light emitting unit 20 in the main body 10 that forms an electrolytic cell, and the window 11 a on the side surface of the main body 10, and the light emitted from the light emitting unit 20. However, it reflects on the wall 40 and proceeds in water, passes through a region where hydrogen bubbles generated by electrolysis are separated from the electrode 30 and diffuses in the water, and then passes through the window 11a to the outside of the main body 10. Since the user can visually recognize this light outside the main body 10 and confirm the state of the hydrogen bubbles traveling in the water, the hydrogen bubbles in the water are illuminated by illuminating the hydrogen bubbles with the light from the inside. Can be surely seen from the window 11a, and even if the window 11a is made small so that light does not easily enter from the outside, a state in which hydrogen bubbles can be seen through the window 11a can be secured, and the window 11a is minimized. Carrying around as a limited size Sufficient strength to withstand a can be granted to the main body portion 10, a reasonably addition to being able to mobile use, is to improve the appearance by increasing the degree of freedom of design of the body portion. In addition, there are no obstacles in the path of the light up to the location where the hydrogen bubbles above the light emitting unit 20 are diffused, and the hydrogen bubbles reach the location of the hydrogen bubbles without being blocked by light. It can be visually confirmed, the generation of hydrogen bubbles can be properly confirmed, giving the user a sense of security, encouraging active use of the device, and reducing power consumption related to light emission, especially the power supply unit When 60 is a battery, use time can be lengthened.

  In the hydrogen water generating apparatus according to the embodiment, the wall 40 is formed in a substantially cylindrical shape with a material such as plastic whose surface has a high brightness, and the surface to which the light from the light emitting unit 20 strikes is made light. However, in addition to this, the window portion 11a reflects a part or all of the light one or more times as a wall portion. As long as it is possible to reach the upper side, a general mirror having another surface property, for example, a transparent and smooth glass plate or a metal plate as a reflective surface attached to the back side of a resin plate Alternatively, a plate-like body having a metallic luster on the surface can be used.

  Further, in the hydrogen water generating apparatus according to the embodiment, the wall portion 40 is configured to be formed in a substantially cylindrical shape that covers the electrode portion 30 from the inner peripheral side so as to accommodate the electrode portion 30 therein. For example, as shown in FIG. 17, the wall portion 42 provided in the electrode portion 35 is erected at a position where light from the light emitting portion 20 is irradiated in the vicinity of the electrode portion 35 to reflect the reflected light. If it can be made to face the window part 11a side, it can also be set as the structure which does not cover the electrode part 35 with the wall part 42 with respect to the light emission part 20 by making the wall part 42 into shapes other than a cylinder shape. And when a part of the light irradiated from the light emission part 20 reaches also the surface of the electrode part 35, as shown in FIG. 17, it reflects on the surface of the electrode part 35, without diffusing light as much as possible, If it is directed to the side with the window portion 11a, the amount of light that illuminates the hydrogen bubbles can be increased, which is desirable.

  Further, in the hydrogen water generating apparatus according to the embodiment, the diffusion state of hydrogen bubbles in the water in the hollow portion can be seen from the outside through one window portion 11 a provided on the side surface of the cylindrical portion 11 of the main body portion 10. However, in addition to this, a plurality of window portions may be provided on the side surface of the main body so that the hollow portions can be seen from the respective window portions. In this case, if the position of each window part is set so that the opening 41 of the wall part 40 is located inside the window part, the light traveling from the light emitting part 20 passes through each window part as in the above embodiment. Immediately before reaching the outside, after illuminating hydrogen bubbles diffusing in water in the vicinity of each window, a state is obtained where the user exits the main body 10 through the window at the shortest distance, and the user can Hydrogen bubbles diffusing in water can be clearly seen.

(Second embodiment of the present invention)
A hydrogen water generator according to a second embodiment of the present invention will be described with reference to FIGS.
In each of the drawings, the hydrogen water generator 2 according to the present embodiment is formed as a cylindrical hollow container closed at both ends, and a main body 10 capable of storing water in the hollow portion 19 and a bottom surface of the main body 10. An electrode part 30 comprising a plurality of electrodes 31, 32, 33 arranged on the upper side of the part 13 b and capable of applying a voltage to water, a wall part 40 provided on the electrode part 30, and a bottom surface of the main body part 10 A control circuit unit 50 that is disposed below the unit 13b and adjusts and controls the energization state of the electrode unit 30; and a power source unit 60 that supplies power to the electrode unit 30 under the control of the control circuit unit 50. It is the composition provided.

  The hydrogen water generating device 2 according to the present embodiment has a configuration common to the hydrogen water generating device 1 according to the first embodiment, but differs from the bottom surface portion 13b below the hollow portion 19 in the main body portion 10 as a different point. The light emitting unit is not provided. Of the components in the hydrogen water generator 2 of the present embodiment, those that are the same as those in the first embodiment are denoted by the same reference numerals, the illustrations are also shared, and the newly illustrated components are different. Only.

  In addition, about the mechanism itself which produces | generates a hydrogen bubble by electrolysis of water, such as the electrode part 30 in the hydrogen water production | generation apparatus 2 which concerns on this embodiment, and each component for electricity supply, it is said 1st. As in the case of the embodiment, it is the same as a known hydrogen water generator, and detailed description thereof is omitted.

  The main body 10 is formed as a hollow container capable of storing a predetermined amount of water therein, and more specifically, a cylindrical body 11 formed in a hollow cylindrical shape and one of the cylindrical body 11 In a state in which the lid body 12 is detachably attached to the cylindrical body portion 11 in a state in which the opening portion 11a is closed, and a bottom surface portion 13b to be the bottom of the electrolytic cell and the other opening portion of the cylindrical body portion 11 is closed. It is the structure provided with the base 13 attached to the cylinder part 11 integrally.

Water is stored in 19 and the water is electrolyzed.

  Each part of the main body 10 is an opaque material that does not transmit light, and can be given an arbitrary color tone according to demand. That is, unlike the main body part in the first embodiment, the main body part 10 in the present embodiment has a configuration in which a window made of a transparent material is not provided on the side surface of the cylindrical part 11 in the main body part 10. However, the configuration of the cylindrical portion 11 other than the window portion is the same as that of the cylindrical portion 11 in the first embodiment, and detailed description thereof is omitted.

The lid body 12 is detachably attached to the cylindrical body portion 11 of the main body portion 10 to close the opening of the cylindrical body portion 11, and a new water passage hole 12 c is provided to be openable and closable so that hydrogen water is required. It can be taken out from the main body 10 in accordance with the above.
The lid 12 is the same as the lid 12 in the first embodiment, including the cartridge 16 attached to the lower side of the lid base 12a, and detailed description thereof is omitted.

  The base portion 13 is a cylindrical body in which two bottomed cylindrical bodies having different sizes are integrally combined to have different sizes in the upper part and the lower part, and a bottom part 13b in which one bottom forms the bottom of the electrolytic cell; In this configuration, the smaller cylindrical portion standing from the bottom surface portion 13 b is screwed and connected to the other end portion of the cylindrical portion 11 so as to be integrated with the cylindrical portion 11. The base portion 13 is provided with the electrode portion 30, the wall portion 40, the control circuit portion 50, and the power source portion 60. The base portion 13 is integrally combined with the cylindrical body portion 11 together with the lid body 12 to form the main body portion 10. A water-tight hollow portion 19 is generated inside.

  Unlike the base portion in the first embodiment, the base portion 13 in the present embodiment is configured such that no light emitting portion is provided on the bottom surface portion 13b of the base portion 13. The configuration of the base portion 13 other than the bottom surface portion 13b is the same as that of the base portion 13 in the first embodiment, including the power switch portion 80, the cartridge state display portion 81, and the connection terminal portion 82 on the side surface of the base portion. Detailed description will be omitted.

The electrode portion 30 is arranged as a substantially cylindrical standing state above the bottom surface portion 13 b of the base portion 13 of the main body portion 10, and three electrodes 31 that can apply a voltage to the water put in the hollow portion 19. , 32, 33.
The electrode unit 30 is the same as the electrode unit 30 in the first embodiment, and a detailed description thereof is omitted.

  The wall portion 40 is a substantially cylindrical body in which two cylindrical bodies having different sizes are integrally combined so as to overlap each other inside and outside, and a gap for accommodating the electrode portion 30 is formed in the middle, and the base portion 13 in the main body portion 10 is formed. It is the structure arrange | positioned in the state which protrudes upwards in the bottom face part 13b upper side. The wall portion 40 is disposed in the vicinity of the electrode portion 30 such that the electrode portion 30 is sandwiched between the inner and outer cylindrical portions forming the wall portion 40. The wall portion 40 is the same as the wall portion 40 in the first embodiment, including a plurality of openings 41 provided in a portion covering the upper electrode portion 30 from above, and detailed description thereof is omitted. However, including the first embodiment, the opening 41 may be formed not only on the upper portion of the wall portion 40 but also on the inner peripheral side.

  However, since the wall portion 40 in this embodiment does not need to reflect light from the light emitting portion, the inner peripheral surface of the wall portion 40 can be a rough surface that is not smooth, and light reflection is also possible. It can also be made of a material whose surface has a low brightness color, for example, black or a material with a color close to it, which increases the degree of absorption.

  The electrode portion 30 positioned in the gap between the wall portions 40 is in a substantially cylindrical standing state, and the ratio of the arrangement region of the electrode portion 30 to the area of the cross section of the main body portion 10 is minimized. In addition, the wall portion 40 is arranged so as to reach the upper side of the electrode portion 30, so that the hollow portion 19 of the main body portion 10 is accidentally or intentionally foreign matter other than water or an input necessary for drinking (for example, Even when ice or the like is charged, it is difficult for the charge to stay on the upper side of the electrode portion 30, and therefore, the possibility that the opening 41 is blocked by the charge is reduced. In this case, the input is guided to the space portion inside the wall portion 40 (see FIG. 21), but the input material that enters the space portion inside the wall portion 40 and reaches the bottom surface portion 13b It is blocked by the wall 40 along the inside of the portion 30 and cannot contact the electrode portion 30 from the side. Thus, by making the wall portion 40 into a substantially cylindrical structure, the input becomes difficult to block the opening 41 on the upper side of the electrode portion 30, and the deformation of the electrode portion 30 can be suppressed to prevent problems, Even in the case where an input is put into the hollow portion 19, it is possible to avoid a situation in which the apparatus is adversely affected.

  The control circuit portion 50 is disposed below the bottom surface portion 13 b of the base portion 13 of the main body portion 10 so as to be isolated from the hollow portion 19 and is electrically connected to the electrodes 31, 32, 33 of the electrode portion 30. Various controls including control of energization to the electrode unit 30 are performed.

  Unlike the control circuit unit in the first embodiment, the control circuit unit 50 in the present embodiment does not provide the light emitting element that forms the light emitting unit on the circuit board, and does not perform control related to the light emitting element of the light emitting unit. It is configured. The configuration and control contents other than those relating to the light emitting unit in the control circuit unit 50 are the same as those in the control circuit unit 50 in the first embodiment, and detailed description thereof is omitted.

  The power supply unit 60 supplies power to the electrode unit 30 and other operating parts under the control of the control circuit unit 50. The power supply unit 60 is the same as the power supply unit 60 in the first embodiment, and a detailed description thereof is omitted.

  Next, the usage state of the hydrogen water generator according to this embodiment will be described. As a premise, the ambient environment temperature of the apparatus is in a state close to room temperature included in a preset electrolyzable range, the power supply unit 60 is charged in advance, and the user operates the power switch unit 80 to operate the electrode unit 30. It shall be in the state which can be supplied with electricity. However, in the initial state of the control circuit unit 50 before the operation, the power supply to each light emitting element and each part of the control circuit is stopped while the input of the user's operation etc. to the power switch unit 80 is detectable. It is assumed that it is in a low power consumption state. Further, it is assumed that the electrodes 31, 32, and 33 of the electrode unit 30 can be electrolyzed with water without any problem when energized without deposits or deterioration. Further, in the recording by the control circuit unit 50, the cumulative electrolysis time in the forward energization state is short, and energization is performed with the forward energization state as the initial setting.

First, the user removes the lid 12 in the main body part 10 from the cylindrical part 11, and in a state where the hollow part 19 is opened, appropriately pours raw water such as tap water into the hollow part 19 to obtain a predetermined amount of water. Add water until When water is added, the lid body 12 is attached to the cylindrical body portion 11 to integrate the main body portion 10, and the hollow portion 19 is isolated from the outside of the main body portion 10 in a watertight state.

When the user pushes the power switch unit 80 to generate hydrogen water after putting water into the main body unit 10, the control circuit unit 50 receives the change in the conduction state of the switch 80b and performs the second operation. A transition is made to a waiting state, and the light emitting element 80c of the power switch unit 80 is turned on in a first predetermined color (for example, white).

After the first operation of the power switch unit 80, before the first preset predetermined time (for example, 3 seconds) elapses, the user performs a second pressing operation on the power switch unit 80. Then, the control circuit unit 50 recognizes that the user has officially instructed hydrogen water generation, starts energization of the electrode unit 30, and sets the light emitting element 80c of the power switch unit 80 to a second predetermined color (for example, , Blue). In this way, energization of each electrode 31, 32, 33 of the electrode part 30 is performed, and electrolysis of water in the hollow part 19 of the main body part 10 proceeds.

After the first operation of the power switch unit 80, if the user does not press the power switch unit 80 for the second time before the first predetermined time elapses, the control circuit unit 50 performs the first operation incorrectly. It is assumed that the next operation is awaited as a new first operation. If the user performs a new pressing operation on the power switch unit 80 before the second predetermined time (for example, 5 seconds) has elapsed from the previous operation, the control circuit unit 50 is newly changed by the user. The second pressing operation to the power switch unit 80 is awaited. On the other hand, if the user does not operate the power switch unit 80 before the second predetermined time elapses from the previous operation, the control circuit unit 50 shifts to the low power consumption state, and the power switch unit The 80 light emitting elements 80c are switched to the extinguished state, and the initial state of waiting for the first pressing operation of the user on the power switch unit 80 is restored.

In a state in which electrolysis of water proceeds by energization of the electrode unit 30, it is publicly known on both the front and back surfaces of the intermediate electrode 32 that is a cathode and facing the inner and outer electrodes 31 and 33 that are anodes. As in the case of electrolysis of water, gaseous hydrogen is generated by reduction, a large amount of hydrogen is generated as fine bubbles on the surface of the electrode 32, and each hydrogen bubble rises along the surface of the electrode 32.

  The hydrogen bubbles rise to reach the opening 41 at the upper portion of the wall 40, the hydrogen bubbles coming out from the opening 41 diffuse into the water, and a large amount of hydrogen dissolves in the water to generate hydrogen water.

In a state in which electrolysis of water proceeds by energization of the electrode unit 30, the control circuit unit 50 has a length of several seconds (for example, 2 seconds) to the power switch unit 80 according to an instruction to interrupt the electrolysis by the user. It is determined whether or not a pressing operation has been performed. If a long pressing operation has been performed, the electrode unit 30 is
Stop energization and finish the electrolysis.

On the other hand, when such a long press operation has not been performed, the control circuit unit 50 continues the electrolysis, and thereafter, the elapsed time from the start of energization to the electrode unit 30 related to the electrolysis is once set in advance. A third predetermined time (for example, 90 minutes) that is half of the electrolysis time (for example, 3 minutes) of
2 seconds), the energized state of the electrode section 30 is changed from the initial forward energized state in which the inner and outer electrodes 31 and 33 are anodes and the intermediate electrode 32 is a cathode to the inner and outer electrodes 31 and 33 as cathodes. And switch to the reverse energization state with the intermediate electrode 32 as the anode.

Thereby, gaseous hydrogen is generated by reduction on each surface of the inner and outer electrodes 31, 33 that are the cathode and facing the intermediate electrode 32 that is the anode due to the reverse energization. 33, a large amount of hydrogen is generated as fine bubbles on the surface, and each hydrogen bubble is generated in the electrodes 31, 33.
Although it will be in a state of rising along the surface, the point that the rising hydrogen bubbles come out only from the opening 41 at the top of the wall 40 is the same as in the forward energization state, and the hydrogen bubbles diffuse into the water of the hollow portion 19. The state is maintained as it is.

The control circuit unit 50 switches the energization state of the electrode unit 30 from the forward direction energization state to the reverse direction energization state, and then again for a few seconds to the power switch unit 80 related to the electrolysis interruption instruction by the user (for example, It is determined whether or not a long press operation for 2 seconds has been performed. Here, when a long press operation is performed, the energization to the electrode unit 30 is stopped, and the electrolysis is finished. When the long press operation is not performed, the control circuit unit 50 continues the electrolysis, and thereafter, the elapsed time from the start of energization to the electrode unit 30 related to the electrolysis is set once. When the electrolysis time (for example, 3 minutes) is reached, the energization to the electrode unit 30 is stopped and the electrolysis is terminated.

  After the energization of the electrode unit 30 is stopped, the control circuit unit 50 switches the light emitting element 80c of the power switch unit 80 from the lighting state to the extinguishing state and reverses the forward energization state to the electrode unit 30 in the previous electrolysis. Based on each duration of the energized state, the cumulative electrolysis time of each energized state is updated and recorded. Further, the control circuit unit 50 updates the number of cartridge use counters by one increment.

Subsequently, the control circuit unit 50 determines whether or not the updated value of the number of cartridge use counters has reached a predetermined value (for example, 318 times) before a preset limit value, and the predetermined value Is reached, it is further determined whether or not the limit value (for example, 360 times) has been reached. If the limit value has been reached, the control circuit unit 50 causes the light emitting element of the cartridge state display unit 81 to 81b is turned on in a predetermined color (for example, red) different from the normal state, and after that, even if the user newly presses the power switch unit 80 twice to instruct execution of electrolysis,
A transition is made to an electrolysis-inhibited state in which energization to the electrode unit 30 is not started. On the other hand, if the limit value has not been reached, the control circuit unit 50 causes the light emitting element 81b of the cartridge state display unit 81 to blink in a predetermined color (for example, green) indicating the normal state of the cartridge 16. The user is notified that it is time to replace the cartridge 16.

  In addition, when the updated value of the cartridge usage counter number does not reach the predetermined value, the control circuit unit 50 shifts to the low power consumption state as a normal end of the electrolysis, and performs a single electric charge. Processing related to the disassembly is completed.

After confirming the end of the electrolysis by turning off the light emitting element 80c of the power switch unit 80, the user releases the locking by the locking portion 12g of the lid body 12 in the main body portion 10 at a desired timing to release the upper lid portion 12b. After the water passage hole 12c is opened, the main body portion 10 is tilted so that the generated hydrogen water is discharged from the hollow portion 19 through the water passage hole 12c, and this hydrogen water is attached to the drinking mouth 12f. You can drink directly or pour into other containers.

In such drinking, when the main body 10 is tilted and the hydrogen water is taken out from the hollow portion 19 through the water passage hole 12 c, the hydrogen water passes through the cartridge 16, and a large number of the hydrogen water gathered downward in the cartridge 16. By contacting with the ceramic material 17, hydrogen water can be purified efficiently,
Even when tap water is used as the raw water, it is possible to obtain hydrogen water suitable for drinking with good water quality that does not cause discomfort due to the odor of lime.

In addition, when the light emitting element 81b of the cartridge state display unit 81 is in a lighting state with a predetermined color different from the normal state or in a blinking state with a predetermined color indicating the normal state, the user performs the first implementation. Similarly to the embodiment, after the cartridge 16 is replaced with a new one, the terminal portion of the charging device is connected to the connection terminal portion 82 on the side surface of the main body portion, and the device is shifted to the charged state to the power source portion 60. After confirming the transition to the charging state from the lighting state of the light emitting element 80c of the power switch unit 80 in a predetermined color, the user performs a long pressing operation on the power switch unit 80 for the fourth predetermined time or more. Then, the control circuit unit 50 resets the number of cartridge use counters to 0, and returns the light emitting element 81b of the cartridge state display unit 81 to a lighting state in a predetermined color indicating a normal state, so that the user power switch unit It returns to the initial state where electrolysis can be performed based on 80 operations.

Thus, in the hydrogen water generating apparatus according to the present embodiment, the ratio of the electrode part 30 to the area of the transverse section of the main body part 10 is arranged in the main body part 10 constituting the electrolytic cell in an upright state. And a wall portion 40 exceeding the height of the electrode portion 30 inside the electrode portion 30.
Therefore, even when ice other than water is accidentally put into the main body 10, there is a state in which the charge is placed on the upper side of the electrode part 30 and is in contact with the electrode part 30 to apply force. In addition, since the input is guided to the space portion inside the substantially cylindrical wall 40, the input does not hinder the rise of hydrogen bubbles coming out from the opening 41 of the wall 40. The input material that has entered the space portion inside the wall portion 40 and has reached the bottom surface portion 13b is blocked by the wall portion 40 and does not contact the electrode portion 30 from the side. Therefore, it is difficult to apply an unnecessary force, the deformation of the electrode part 30 can be suppressed and problems can be prevented, and a situation in which the apparatus is adversely affected can be avoided even when the charged substance is put into the main body part 10.

  In the hydrogen water generator according to each of the above embodiments, the upper portion of the wall portion 40 is formed so as to reach the upper side of the electrode portion 30 so as to cover the electrode portion 30 from above. Is not limited to a partial one like the opening 41, and if the wall has a shape slightly higher than the height of the electrode 30, the wall 40 extends above the electrode 30. There is no need to cover.

  Moreover, although each part of the main-body part 10 in 2nd Embodiment is made into the opaque material which does not permeate | transmit light, when appealing the state of a bubble as a fine bubble, a window part may be formed like 1st Embodiment. The whole can be made of a transparent material.
