FIG. 5 is a cross-sectional view of the hydrogen water generation filter 12. The hydrogen water generation filter 12 includes a cylindrical body 24 made of a fired and molded magnesium-containing composition in a cylindrical case 25. At the upper part of the cylindrical case 25, an inlet 26 for water is formed at the peripheral edge, and an outlet 27 is formed at the center.
The cylindrical body 24 is formed by pressing and baking magnesium alone or a mixture of magnesium and an inorganic material or an organic material into a cylindrical shape. By firing and molding in this manner, discharge of dust powder into water is prevented. As the cylindrical body 24, magnesium alone or a mixture of magnesium and an inorganic material or an organic material in a nonwoven fabric can be used.

The water flowing in from the inlet 26 flows from the outer peripheral portion of the cylindrical body 24 to the central portion and is discharged from the outlet 27. In this flow of water, hydrogen is generated in contact with magnesium, and hydrogen water is generated. By setting it as the cylindrical body 24, the surface area which reacts with water can be increased and highly active hydrogen water can be produced | generated. This hydrogen water is strongly alkaline having a pH of 10 or higher.
Even if the inlet 26 and the outlet 27 are reversed, the same effect can be obtained.

  FIG. 6 is a cross-sectional view of the cation exchange resin filter 13. The cation exchange resin filter 13 has a cylindrical case 28 in which a cation exchange resin 29 is built. In the upper part of the cylindrical case 28, an inlet 30 for water is formed at the periphery, and an outlet 31 is formed at the center. The cation exchange resin 29 is accommodated in an inner cylinder, and water is infiltrated into the inside from the lower part of the inner cylinder. Acidic water is produced in the process of passing water through the cation exchange resin from the bottom to the top.

Referring to FIG. 4, a valve 32 is provided on the inlet side piping of the hydrogen water generation filter 12 and the cation exchange resin filter 13 to control the amount of water entering the cation exchange resin filter 13 . The opening adjustment of the valve 32 is manual. By adjusting the valve 32, the alkalinity of the hydrogen water discharged from the drain port 5 can be adjusted. In this embodiment, the pH is adjusted to weak alkalinity of about 9.5.
In the above embodiment, the hydrogen water generation filter 12 and the cation exchange resin filter 13 are arranged in parallel, but a series arrangement is also possible.

In FIG. 4, the pressure adjusting means 21 will be described.
The pressure adjusting means 21 is provided for preventing water leakage because there is a possibility that water leakage may occur due to the pressure of hydrogen gas generated in the hydrogen water generation filter 12 when the user does not use the product for a long time. It is.
The pressure adjusting means 21 has a tank 33 provided in an outlet side pipe on the downstream side of the hydrogen water generation filter 12. The tank 33 is hermetically sealed and has an inlet at the top and an outlet at the bottom. Outlet piping is connected to the inlet and outlet.

A return pipe 34 branched from the outlet side pipe connected to the outlet of the tank 33 and connected to the suction port side of the pump 20 is provided.
A bypass pipe 35 that bypasses the tank 33 and connects to the outlet side pipe is formed. The return pipe 34 is connected to the outlet pipe upstream of the downstream end connection point of the bypass pipe 35. A check valve 33 a for preventing a back flow toward the tank 33 is provided on the outlet side pipe between the outlet side pipe connection end of the return pipe 34 and the tank 33.

  A float valve 33 b is provided in the tank 33. The float valve 33b controls the inflow of hydrogen water into the tank. When the water level in the tank is lower than a predetermined position, the valve is opened to allow water to flow in. When the water level is higher than the predetermined position, the valve is closed. This prevents inflow into the tank. The float valve 33b closes the valve when the float position is higher than a predetermined position. In this closed state, when the internal pressure of the pipe becomes high, the valve is pushed open, and a small amount of hydrogen water or hydrogen (gas). Is allowed to flow into the tank 33.

The operation of the float valve 33b will be described.
First, since the tank 33 is empty when the apparatus is used, the float of the float valve 33b is lowered and the valve 33b is open.
The water supply pump 20 is started by operating the button of the operation unit 3, and the solenoid valves 22 and 23 are opened after 1 second. At this time, the valve of the float valve 33b in the tank 33 is open, and hydrogen water flows into the tank. Then, the water level in the tank 33 rises, the float rises, and the valve 33b is closed when it reaches a predetermined position.

At this time, the water sent by the water supply pump 20 flows into the tank 33 and is drained from the drain outlet 5 through the bypass pipe 35. After the float valve 33b is closed, the water is drained through the bypass pipe 35.
When a predetermined amount of hydrogen water is discharged from the drain port 5, the solenoids 22 and 23 are closed and the water supply pump 20 is stopped at the same time.

  The above is the first use, but in the normal use after that, the float valve 33b is closed, so that the hydrogen water is discharged from the discharge port 5 through the bypass pipe 35. At this time, the water in the outlet side pipe is circulated to the water supply pump 20 via the return pipe 34. This amount of circulation is 1 to 3% of the total amount of water. This circulating water amount adjustment is performed by the valve 36. This valve 36 is manually operated.

When the water level in the tank 33 falls due to the circulation, the float valve 33b opens, hydrogen water is supplied into the tank 33, and the valve 33b closes when the water level rises. Such operations are repeated to perform stable drainage.
When not in use for a long period of time, hydrogen gas is generated in the hydrogen water generation filter 12 to increase the internal pressure in the pipe. At this time, although the float valve 33b is closed, the pressure gradually increased by the hydrogen gas momentarily opens the valve of the float valve 33b, and a small amount of hydrogen gas or hydrogen water flows into the tank 33, and the inside of the piping The pressure balance is maintained.

The pressure adjusting means 21 suppresses an increase in pressure in the pipe when not used for a long period of time, thereby preventing water leakage.
As shown in FIG. 4, the hydrogen water production apparatus is provided with a control device 37 that controls the water supply pump 20, the solenoid valves 22 and 23, and the like. The control device 37 controls the water supply pump 20 to stop draining for a predetermined time when the discharge amount from the drain port 5 continuously exceeds a predetermined amount.

In FIG. 7, the control flow of the feed water pump 20 by the said control apparatus 37 is shown.
The operation button of the operation unit 3 provided on the front surface of the hydrogen water production apparatus is operated (S1). By this button operation, the water supply pump 20 is activated and the solenoid valves 22 and 23 are opened (S2). An average of 15 ml / sec of hydrogen water is discharged from the drain port 5 (S3). After the solenoid operation, it is determined whether the interval exceeds 300 seconds before the next operation (S4). If not exceeded, the solenoid operating time is added up (S5). It is determined whether the total operating time of the solenoids 22 and 23 has exceeded 110 seconds (S6). If not, the process returns to S4. If it exceeds, the function of the operation button is forcibly stopped (S7). It is determined whether the forced stop has elapsed for 5 minutes (S8). If not, the process returns to S7. If it has elapsed, the total solenoid operating time is initialized (S9). Then, the process proceeds to S4.

The above control is for preventing the hydrogen concentration from decreasing when water is continuously discharged for a long time.
According to the above-described embodiment, a hydrogen-dissolved amount of about 1,600 ppb of hydrogen water can be generated, and the water-dissolved 1,000 ppb can be maintained for 5 hours after pouring into a cup.
The organic matter removal filter 14 and the microorganism removal filter 15 are preferably replaced in about 6 to 12 months. The hydrogen water generation filter 12 and the cation exchange resin filter 13 are also preferably replaced every about 6 to 12 months or about every 1,080 liters used.
