A tube fixing portion 46a for fixing a tube (reference numeral is omitted) connected to the discharge port of the ion exchange resin filter 31 is formed on the upper end side of the water supply joint 46, and below the tube fixing portion 46a. Is formed integrally with a valve body mounting portion 46b for mounting a float valve body 47 to be described later. A discharge hole 46d having a diameter larger than that of the water supply hole 46c is formed in the valve body mounting portion 46b, and a tapered hole having a tapered surface that decreases in diameter toward the water supply hole 46c is formed at the upper end of the discharge hole 46d. 46 f is formed, and a part of the valve body mounting portion 46 b is formed with a notch (reference numeral is omitted) in which a later-described support body 47 c of the float valve body 47 can be rotated.

In the electrolyzer 32, a float valve body 47 for maintaining the predetermined amount of ultrapure water supplied from the water supply hole 46 c is mounted on the valve body mounting portion 46 b of the water supply joint 46. . The float valve body 47 prevents the inflow of the ultrapure water when the ultrapure water reaches a predetermined amount, and includes a floating body 47a that is sealed in a hollow shape and floats on the water surface, The rod 47b is composed of a floating body 47a and an L-shaped support 47c that supports the valve rod 47b. The support 47c has a floating body 47a fixed to one end side, and the other end is rotatably supported by a valve body mounting portion 46b of the water supply joint 46 by a pin 47d. Further, a valve rod 47b is erected on the other end side of the support 47c, and the taper is formed on the upper end of the valve rod 47b by rotating the support 47c counterclockwise as shown in FIG. A tapered convex portion 47f having a tapered surface that can be in close contact with the hole 46f is formed.

When the surface of the ultrapure water stored in the electrolyzer 32 is reduced by a certain amount, the float valve body 47 is lowered at the front end side of the floating body 47a, and this lowering causes the support 47c to pass through the support body 47c. The tapered protrusion 47f of the valve rod 47b is separated from the tapered hole 46f of the water supply joint 46 to form a gap, and ultrapure water from the ion exchange resin filter 31 is pumped into the inside through this gap. When the amount of ultrapure water stored in the electrolyzer 32 increases, the leading end of the floating body 47a rises accordingly, and when the amount of stored water reaches a predetermined amount, the support 47c is interposed. The tapered protrusion 47f of the valve rod 47b is brought into close contact with the tapered hole 46f of the water supply joint 46, and the supply of ultrapure water pumped from the ion exchange resin filter 31 is prevented by this close contact state.

Further, in the electrolysis apparatus 32, an electrolysis unit 40 that generates hydrogen gas and oxygen gas by electrolysis is disposed in the body 33a of the inner container 34 shown in FIG. In the electrolysis section 40, a cathode side electrode rod 48 and an anode side electrode rod 49 are fixed to the body portion 33a so as to face each other in an insulated state, and one cathode side electrode rod 48 is formed in a plate shape. The cathode electrolytic plate 51 with titanium platinum plating on the surface is fixed, and the anode electrode plate 49 with the titanium platinum plating on the plate-shaped surface is attached to the other anode side electrode rod 49. It is fixed so as to face the cathode electrolytic plate 51. The cathode electrolytic plate 51 and the anode electrolytic plate 52 are disposed below the flow port 34a of the inner vessel 34, and an ion exchange film 53 is provided in a gap between the cathode electrolytic plate 51 and the anode electrolytic plate 52 facing each other. The cathode electrolytic plate 51 and the anode electrolytic plate 52 are separated from each other by the ion exchange film 53. Further, around the cathode electrolytic plate 51 and the anode electrolytic plate 52, a net body 54 having a mesh capable of freely flowing pure water is disposed.

In the electrolysis apparatus 32 configured as described above, the deionized water (electrolytic solution) stored therein is electrolyzed by energizing the cathode side electrode rod 48 and the anode side electrode rod 49 shown in FIG. Then, hydrogen gas (H ₂ ) is generated on one cathode electrolytic plate 51 side. This hydrogen gas is discharged to the hydrogen gas discharge port 38d of the hydrogen gas duct 38 through the hydrogen gas flow path 43, and one of the hydrogen gases is connected via the piping member 56 (see FIG. 3) connected to the hydrogen gas discharge port 38d. It is sent to the carbon air filter 57. Further, oxygen gas (O ₂ ) is generated on the other anode electrolytic plate 52 side, and this oxygen gas is discharged through the oxygen gas flow path 44 to the oxygen gas discharge port 39d of the oxygen gas duct 39. It is sent to the other oxygen delivery fan 59 through a piping member 58 connected to the oxygen gas discharge port 39d.

Among these, in one carbon air filter 57, bubbles contained in the hydrogen gas generated by the electrolysis device 32 are removed by a filtering material such as carbon powder (not shown). A circulation pump 62 is connected to the carbon air filter 57 via a tube (reference numerals are omitted). The circulation pump 62 is driven only when the electrolysis device 32 is operated. The circulation pump 62 includes a gas inlet 62a connected to the carbon air filter 57 and one end of the cold water tank 22 described above. And a water suction port 62b connected to the other end of the pipe body (the reference numeral is omitted) is disposed, and when the circulation pump 62 is driven, the carbon air filter 57 is connected to one of the gas suction ports 62a. From the cold water tank 22 is sucked through the other water suction port 62b.

In the circulation pump 62, the sucked hydrogen gas (H ₂ ) and water (H ₂ O) are mixed by a pump mechanism (not shown) by a pump mechanism (not shown), and hydrogen water (H ₂ + H ₂ O), which is pumped from the discharge port 62c. The discharge port 62c of the circulation pump 62 is connected to the bubble miniaturization filter 63 via a tube (reference numerals are omitted). The bubble miniaturization filter 63 is a built-in semipermeable membrane having a micropore (not shown) of 0.0001 μm (about 1 / 1,000,000 of hair), and the circulation pump 62 is formed by the semipermeable membrane. The hydrogen gas bubbles pumped from are refined to increase the amount of dissolved hydrogen in the hydrogen water. The bubble miniaturizing filter 63 is connected to the cold water tank 22 through a tube (reference numerals are omitted).

Therefore, as shown in FIG. 3, the hydrogen water from the bubble miniaturization filter 63 is pumped and stored in the cold water tank 22, and the hydrogen water stored in the cold water tank 22 is stored in the circulation pump 62. By being driven, it is sucked from the water suction port 62b of the circulation pump 62 and mixed with the hydrogen gas from the carbon air filter 57 sucked from the gas suction port 62a, and the discharge port 62c of the circulation pump 62 From the above, the air is refined and stored in the cold water tank 22 through the bubble refining filter 63. That is, the hydrogen water stored in the cold water tank 22 is circulated through the cold water tank 22, the circulation pump 62 and the bubble refinement filter 63 constituting the circulation route of the present invention, so that the amount of dissolved hydrogen in the treated water is reduced. It gradually increases, and the user can drink in a state where the amount of dissolved hydrogen is close to saturation.

The other oxygen delivery fan 59 connected to the electrolysis device 32 is driven only while the electrolysis device 32 is in operation, and when the oxygen delivery fan 59 is driven, the electrolysis device Oxygen generated by 32 is sucked from the electrolysis device 32 and sent out into the oxygen suction tube 7 shown in FIG. The user can suck oxygen gas from the oxygen gas discharge port 7a of the oxygen suction tube 7 while the electrolysis device 32 is in operation.

The electrolysis device 32 is operated by the bright signal of the light illuminance sensor 9C described above or by pressing the oxygen release switch 9A even when not activated by the dark signal from the light illuminance sensor 9C (forcedly). The circulation pump 62 and the oxygen delivery fan 59 are driven simultaneously with the operation of the electrolyzer 32. Further, the time for the electrolyzer 32 and the like to operate is set to 15 minutes by the hydrogen generation operation timer 9H connected to the control device 20 shown in FIG. The time is set to 45 minutes by the hydrogen generation pause timer 9I connected to the control device 20. These set times are not limited to the set times described above, and can be freely changed according to the frequency of drinking hydrogen water from the cold water outlet 3.

Next, a procedure for generating hydrogen gas by the electrolytic water purification apparatus 1 to store hydrogen water and generating oxygen gas, and an operation effect thereof will be described with reference to a flowchart shown in FIG. In the preparatory stage before the electrolytic water purifier 1 is operated, the set time of the hydrogen generation operation timer 9H is set to 15 minutes, the set time of the hydrogen generation stop timer 9I is set to 45 minutes, and the light intensity sensor The set illuminance of 9C is set to illuminance corresponding to the use time zone of the electrolytic water purifier 1 (indoor illuminance in the sunshine hours body). Moreover, the water stop valve 11 shown in FIG. 1 is previously opened manually.

In the first step St1, whether or not the amount of water in the reserve tank 18 is a predetermined amount is determined by the control device 20 via the micro switch 21c of the float switch 21, and it is determined that the predetermined amount has not been reached. Advances to step St2, and if it is determined that the predetermined amount has been reached, advances to the next step St3. Among these, when the process proceeds to step St2, the electromagnetic valve 14 is opened and the pressurizing pump 15 is driven, so that the sediment filter 12, the carbon filter 13, the electromagnetic valve 14, and the reverse osmosis membrane filter are driven. 16 and the ore filter 17 are used to pump the purified water and replenish it to the spare tank 18, and the routine returns to step St1 to repeatedly determine whether or not the amount of water in the spare tank 18 is a predetermined amount. The water pumped by the pressurizing pump 15 is also branched from the reverse osmosis membrane filter 16 to the ion exchange resin filter 31, and the tapered hole 46f of the water supply joint 46 disposed in the electrolysis device 32 is opened. If so, the electrolyzer 32 is also purified and replenished with water.

When the process proceeds to the next step St3, whether or not the illuminance of the light illuminance sensor 9C is the set illuminance is determined by the control device 20 via the light illuminance sensor 9C, and it is determined that the set illuminance has not been reached. In this case, the process returns to step St3 and is repeated, and when it is determined that the set illuminance has been reached, the process proceeds to the next step St4. When the process proceeds to the next step St4, the electrolysis device 32 is activated, and the circulation pump 62 and the oxygen delivery fan 59 are driven, so that hydrogen gas, oxygen gas and Is generated, and the process proceeds to the next step St5.

This lighting state is the above electrolyzer in step St6 described later. 32 until the operation of 32 is stopped. The hydrogen gas generated by the electrolysis device 32 is sucked into the circulation pump 62 through the carbon air filter 57 and mixed with the hydrogen water from the cold water tank 22, and the hydrogen gas passes through the bubble refinement filter 63. Is returned to the cold water tank 22 again as dissolved hydrogen water. By circulating through these circulation routes, the amount of dissolved hydrogen in the treated water gradually increases, and the user can drink in a state where the amount of dissolved hydrogen is close to saturation. Further, the oxygen gas generated by the electrolysis device 32 is sent out by the oxygen sending fan 59 and can be sucked from the tip of the oxygen suction tube 7.

In the next step St5, whether or not the operating time of the electrolyzer 32 has elapsed for 15 minutes is determined by the control device 20 via the hydrogen generation operation timer 9H, and the operating time of the electrolyzer 32 and the like is determined. If it is determined that 15 minutes have not elapsed, the process returns to step St4 and is repeated. If it is determined that 15 minutes have elapsed for the electrolyzer 32 or the like, the next step St6 is performed. Proceed to When the process proceeds to the next step St6, the operation of the electrolysis device 32 is stopped and the driving of the circulation pump 62 and the oxygen delivery fan 59 is stopped, so that hydrogen gas and oxygen gas by the electrolysis device 32 are stopped. Is paused, and the process proceeds to the next step St7. When the operation of the electrolyzer 32 is stopped in step St6, the hydrogen / oxygen resting lamp 8E of the display panel 8 shown in FIG. 2 is turned on. This lighting is performed in the next step St4. The operation is continued until the operation is started.

In the next step St7, whether or not the oxygen release switch 9A is ON is determined by the control device 20 via the oxygen release switch 9A. If it is determined that the oxygen release switch 9A is ON, the process returns to step St4. The electrolysis device 32 is operated repeatedly, and the circulation pump 62 and the oxygen delivery fan 59 are driven to generate hydrogen gas and oxygen gas by the electrolysis of the electrolysis device 32, and not ON ( If it is determined that it is OFF, the process proceeds to the next step St8. In step St4, the condition for determining that the oxygen release switch 9A is ON is that the hydrogen / oxygen resting lamp 8E is lit and hydrogen gas and oxygen gas are not generated. The condition is that the oxygen release switch 9A is pressed in order for the user to suck oxygen gas.

When the process proceeds to the next step St8, it is determined by the control device 20 via the hydrogen generation pause timer 9I whether or not the pause time of the electrolyzer 32 etc. has passed 45 minutes, and the electrolyzer 32 etc. If it is determined that the pause time has not elapsed for 45 minutes, the process returns to step St6 and is repeated. If it is determined that the operation time of the electrolyzer 32 or the like has elapsed for 45 minutes, step St3 To go back and repeat.

As described above, the electrolytic water purifier 1 according to the present embodiment is not always operated continuously, for example, at midnight (while sleeping) that does not require drinking of hydrogen water or ingestion of oxygen gas.
