Description

  The present invention relates to a hydrogen water generator and a hydrogen water generator including a hydrogen water generator.

  In the body, mitochondria generate active oxygen during energy generation, and when this active oxygen accumulates in the body, it oxidizes cells and destroys cell membranes and damages DNA, causing various diseases. It has been reported. Therefore, it is necessary to eliminate active oxygen for beauty, health and diet.

  In recent years, it has become well known that hydrogen can reduce active oxygen by incorporating hydrogen water, and the demand for hydrogen water is increasing for beauty, health and diet.

Various apparatuses for producing hydrogen water have been disclosed (Patent Document 1) and are also provided on the market. However, most of them generate hydrogen by electrolysis of water, and since energization is necessary, the apparatus is complicated and expensive (Japanese Patent Laid-Open No. 2005-186034).
As a simpler hydrogen water generator, water can be generated by simply putting water into a PET bottle or cup and then adding it into the metal. Magnesium, quartz stone, obsidian, tourmaline, antibacterial sand, weathered coral, silicon A ball-shaped hydrogen generator containing benzene is disclosed (Japanese Patent Laid-Open No. 2013-82585).
In sports gyms, high-concentration hydrogen water containing aluminum pouches is sold at vending machines. Such hydrogen water is manufactured by filling hydrogen with water under high pressure.

Japanese Patent Laid-Open No. 2005-186034 JP2013-82585A

As described above, in the technology already disclosed, it is necessary to purchase an expensive apparatus or to purchase commercially available high-concentration hydrogen water as needed. Moreover, even if a means using a simple hydrogen generator is used, hydrogen water must be prepared for each cup, and it is difficult to prepare the next cup unless the generated hydrogen water is consumed.
Therefore, the present inventor thinks that hydrogen water can be drunk more easily and on a daily basis if hydrogen water can be generated simply by twisting the tap, and a hydrogen water generating device attached to the tap is completed. It came to.
Therefore, this invention makes it a subject to provide the instrument which can produce | generate hydrogen water easily from tap water.

  The present invention relates to a housing having a water inlet and a water outlet, a first filter provided in the water inlet, a second filter provided in the water outlet, and a housing including the two filters. A hydrogen water generator is provided that includes magnesium metal and a zeolite in between.

Since the hydrogen water generator of the present invention contains metallic magnesium, hydrogen is generated by the contact between the water introduced into the housing and the metallic magnesium, and hydrogen water can be produced. In addition, zeolite has the ability to take in cations, and magnesium ions become magnesium oxide and adhere to the surface of metal magnesium, eliminating the factors that hinder the production of hydrogen, thus stabilizing the hydrogen concentration of hydrogen water. Have.
The two filters provided at the water inlet and the water outlet of the hydrogen water generator of the present invention enclose a material such as magnesium metal and zeolite filled in the housing, while introducing water from the outside and from the inside of the housing. There is no particular limitation as long as the material and structure do not hinder the water from flowing out.
Examples of the filter material include fibrous activated carbon, nonwoven fabric, and sintered body. When a material with weak structural strength such as a nonwoven fabric is used, a strength member such as a frame may be further provided. Since a sintered filter using a sintered body has strength, a strength member is not necessary.

  In one aspect of the hydrogen water generator of the present invention, one or a plurality of layers having a hydrogen water generating ability including a metal magnesium layer on the water inlet side and a zeolite layer on the water outlet side are arranged.

In one embodiment of the hydrogen water generator of the present invention, activated carbon is further included between the two filters.
Activated carbon has not only a water purification function for removing chlorine compounds and the like, but also a hydrogen storage capacity.
The activated carbon can be included as an activated carbon layer independent of the magnesium metal layer and the zeolite layer.
Regarding the arrangement of the activated carbon layer and the multilayer composed of the magnesium metal layer and the zeolite layer, any layer may be on the inlet side, but from the viewpoint of effectively utilizing the hydrogen storage capacity of the activated carbon, It is preferable to arrange a multilayer composed of a layer and a zeolite layer on the water inlet side and the activated carbon layer on the water outlet side.

Moreover, as another aspect of the hydrogen water generator of the present invention, activated carbon can be included as a layer of a mixture of magnesium metal and activated carbon.
In this case, from the viewpoint of effectively utilizing the cation uptake ability of zeolite, it is preferable to dispose a layer of a mixture of metallic magnesium and activated carbon on the water inlet side and a zeolite layer on the water outlet side.

  In another aspect, the present invention includes a hydrogen water generating unit and a raw water receiving unit, wherein the hydrogen water generating unit and the raw water receiving unit communicate with each other through a communication unit so that water can pass therethrough. The hydrogen water generating unit is fitted with the hydrogen water generator receiving unit for receiving the hydrogen water generator of the present invention and the hydrogen water generator receiving unit, and covers the hydrogen water generator in a liquid-tight manner. The raw water receiving unit includes a cap and a water receiving port that receives the raw water by connecting to a tap and a water supply port that circulates the received raw water to the hydrogen water generating unit via the communication unit. A hydrogen water generator characterized by the above is provided.

  The hydrogen water generator of the present invention can be attached to a tap of a water supply, and the hydrogen water generator of the present invention is mounted as a cartridge so that the raw water of the water is discharged from the water inlet upstream of the hydrogen water generator. Hydrogen water can be generated by passing water toward the water inlet.

The solubility of hydrogen in water is 1.62 ppm at room temperature and normal pressure, and the medical effect of hydrogen water is said to be about 1 ppm (1000 ppb).
If it is an expensive electrolysis-type hydrogen water generator, hydrogen water of about 1000 ppb can be obtained. If hydrogen is filled in water at a high pressure, hydrogen water having a concentration higher than the above-described solubility can be obtained. . Since hydrogen is degassed from hydrogen water having a relatively high hydrogen concentration, if an effect of high concentration hydrogen water is to be obtained, it must be drunk up early.
However, about 100 ppb is considered sufficient for cosmetic health purposes. The cumulative effect obtained by continuously drinking low-concentration hydrogen water is considered to be greater than occasional intake of high-concentration hydrogen water.

  By simply passing raw water through the hydrogen water generator of the present invention, hydrogen water having a hydrogen concentration exceeding about 100 ppb and up to about 1000 ppb can be obtained. Can be drunk.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following forms are illustrations for explaining the present invention, and the present invention is not limited to the following forms.

FIG. 1 is a schematic view showing a state in which the hydrogen water generator 1 is attached to a tap 2, and FIG. 2 is a schematic cross-sectional view of the hydrogen water generator 1.
The hydrogen water generator 1 includes a hydrogen water generator 11 and a raw water receiver 12. The hydrogen water generating unit 11 and the raw water receiving unit 12 are communicated with each other through the communication unit 13 so that water can be passed therethrough.
The hydrogen water generator 3 is provided in a housing 31 having a water inlet 311 on the upstream side and a water outlet 312 on the downstream side, and a sintered filter 32a and a water outlet 312 as a first filter provided in the water inlet 311. The second filter includes a sintered filter 32b and a metal magnesium layer 35 and a zeolite layer 36 in the housing 31 and between the two sintered filters.

The hydrogen water generator 11 includes a hydrogen water generator receiver 111 that receives the hydrogen water generator 3 of the present invention, and a cap that fits the hydrogen water generator 3 in a liquid-tight manner by fitting with the hydrogen water generator receiver 111. 112. The hydrogen water generator receiving portion 111 has an opening 111a from the communication portion 13 and a hydrogen water discharge port 111b for discharging hydrogen water.
The raw water receiving part main body 121 of the raw water receiving part 12 is connected to the tap 2 of the water supply and receives the raw water receiving part 121a for receiving the raw water of the water supply and the hydrogen water generating part 11 through the communication part 13 for the received raw water. And a raw water discharge port 121c for discharging the received raw water as it is. Moreover, the flow path switch 122 is provided in the side surface of the raw | natural water receiving part main body 121, and the flow path to the raw | natural water feed port 121b and the flow path to the raw | natural water discharge port 121c can be switched.

  The raw water discharged from the water tap flows into the raw water receiving section 12 from the raw water receiving port 121a, and the flow path to the raw water discharging port 121c is opened by the operation of the flow path switching switch 122 to be discharged as raw water. When the flow path to the raw water discharge port 121c is closed by the operation of the flow path switch 122 and the flow path to the raw water supply port 121b is opened, the raw water passes through the communication unit 13 to the hydrogen water generation unit 11. Watered.

  A recess is formed in the bottom of the hydrogen water generator receiving portion 111, and the lower part of the hydrogen water generator 3 is fitted in the recess. When the cap 112 is fitted to the hydrogen water generator receiving portion 111 in this state, the hydrogen water generator 3 is covered. Since the O-ring is sandwiched between the recess and the lower part of the hydrogen water generator 3 and between the hydrogen water generator receiving portion 111 and the cap 112, the hydrogen water generator 3 is covered in a liquid-tight manner.

  The raw water flowing into the hydrogen water generator 11 is not directly discharged from the hydrogen water discharge port 111b, fills the space between the inner wall of the cap 112 and the hydrogen water generator 3, and the housing of the hydrogen water generator 3 Hydrogen water flows into the housing 31 through a water inlet 311 provided on the upstream side of 31 and reacts with metallic magnesium inside the housing 31 to generate hydrogen water. The generated hydrogen water flows out from the water outlet 312 provided on the downstream side of the housing, and is discharged from the hydrogen water outlet 111 b of the hydrogen water generator receiving portion 111.

  A conventional water purifier 4 (cartridge) includes a housing 41 having a water inlet 411 on the upstream side and a water outlet 412 on the downstream side, and a sintered filter 42 a and a water outlet 412 as a first filter provided in the water inlet 411. A sintered filter 42b is provided as a second filter provided, and activated carbon 43 is included in the housing 41 between the two sintered filters (FIG. 8).

  The conventional water purifier 4 (cartridge) is filled with activated carbon 43 instead of the metal magnesium layer 35 and the zeolite layer 36 contained in the housing 31. Except for this point, the hydrogen water generating apparatus of the present invention. The water flow from the faucet 2 to the hydrogen water discharge port 111b is the same as that of the conventional water purifier.

  The hydrogen water generator 3 of the present invention is filled with metallic magnesium having hydrogen water generating ability. When water contacts metal magnesium, hydrogen is generated according to Reaction Formula I, and the metal magnesium becomes magnesium hydroxide.

  Magnesium hydroxide produced on the right side of reaction formula I is further converted into magnesium oxide according to reaction formula II.

  Magnesium oxide (MgO) is a stable substance, and when a film is formed on the surface of magnesium metal, hydrogen generation is suppressed. Therefore, it is desirable to inhibit the progress of Reaction Formula II and inhibit the production of MgO. For that purpose, it is necessary to dry it so that water does not disappear at the stage of reaction formula I and to drive out magnesium ions out of the system.

  In the preliminary experiment, the inventors did not stabilize the hydrogen concentration when the hydrogen water was repeatedly generated with only metallic magnesium, but it was repeatedly generated when the metallic magnesium and zeolite coexisted. It was clarified that the fluctuation of the hydrogen concentration was small and converged to a constant value (FIG. 11). When metal magnesium and zeolite coexist, it is considered that the purpose of the zeolite to take in magnesium ions and inhibit the production of MgO is achieved.

In the present invention, coexistence of metallic magnesium and zeolite means that metallic magnesium and zeolite are present inside the hydrogen water generator so that water flowing into the hydrogen water generator is brought into contact with both metal magnesium and zeolite. Means that.
Coexistence of metallic magnesium and zeolite is, for example, a multilayer formed by placing a layer of a mixture of metallic magnesium and zeolite inside the hydrogen water generator, and contacting the metallic magnesium layer and the zeolite layer. It can be achieved by arranging the metal magnesium layer and the zeolite layer without contacting each other as a single layer.
The metal magnesium and zeolite multilayers, the metal magnesium monolayer and the zeolite monolayer can be independently arranged in one or more layers, and the multilayer and each single layer can be appropriately combined. .
The magnesium metal layer and the zeolite layer may be arranged in any order. For example, the metal magnesium layer may be arranged on the water inlet side of the hydrogen water generator, and the zeolite layer may be arranged on the water outlet side. it can.

Moreover, the water purification function of this invention can be provided with a water purification function. Chlorine is added to the raw water for sterilization. In Japan, chlorine is disinfected so that water in the faucet (faucet) retains 0.1 mg / L (0.1 ppm) or more of free residual chlorine based on the Water Supply Law. It is stipulated that
Currently, chlorine (liquefied chlorine), sodium hypochlorite (NaClO), chlorine dioxide, etc. are used as chlorinated disinfectants, and these break into the cells of pathogenic organisms and destroy the functions of DNA and the like. Is disinfected by. Furthermore, carcinogenic substances such as trihalomethane are also produced. Although the residual concentration of these chlorinated substances is low and does not directly affect the human body, it is preferably removed in consideration of beauty and health. These chlorinated substances can be removed by decomposition or adsorption when water is passed through a porous substance such as activated carbon.

The hydrogen water generator 3 of the present application can include activated carbon in order to impart water purification capability in addition to metal magnesium and zeolite having a hydrogen water production stabilizing function.
Activated carbon can be arranged alone as an activated carbon layer, or can be mixed with metallic magnesium or zeolite and arranged as a mixed layer.
The activated carbon layer may be arranged in any order with respect to the metallic magnesium layer and the zeolite layer. For example, the metallic magnesium layer is arranged on the inlet side of the hydrogen water generator, and the activated carbon layer is arranged on the outlet side. Can be arranged.

  In the present invention, metallic magnesium may be used in any shape such as a cut shape, a powder shape, a granular shape, and a plate shape.

  Zeolite is a hydrous aluminosilicate containing an alkali or alkaline earth metal and is well known as a pore material. The pore diameter in the structure is usually about 0.2 to 1.0 nm (2 to 10 mm).

  Activated carbon is made by heating carbon substances such as coconut shells and pulps at a high temperature of about 1000 ° C, and there are many types with pore diameters of 2 nm or less (microporous material) to those exceeding 1000 nm (macroporous material). To do. There are various shapes such as powder, granule, fiber, cloth, and honeycomb.

  Examples relating to the present invention will be described below, but these do not limit the present invention.

Example 1
(1) Production of hydrogen water generator with water purification function A hydrogen water generator (cartridge) of a first specific example is shown in FIG.
A housing 31 having a sintered filter 32b is prepared at the bottom, 15 g of zeolite is uniformly spread on the sintered filter 32b, 10 g of metal magnesium is spread thereon, and the metal magnesium layer 35 and the downstream are arranged on the upstream side. A multi-layer 37 composed of a zeolite layer 36 was formed on the side. An activated carbon layer 34 made of fibrous activated carbon was formed thereon, and an activated carbon layer 33 made of 16 g of granular activated carbon was further formed thereon. In a normal water purifier, as will be described later, 32 g of granular activated carbon is filled in a housing 41 having the same size as the housing 31. However, in the hydrogen water generator of the present invention, most of the volume of the housing is made of metal magnesium and Since the zeolite occupies, the amount of activated carbon is reduced by half and the ability to remove chlorine substances decreases. Therefore, an activated carbon layer 34 made of fibrous activated carbon is disposed to compensate for the chlorine substance removing ability. Finally, the lid was covered with the sintered filter 32a to produce a hydrogen water generator of the first specific example.

(2) Measurement of hydrogen water generation capacity A hydrogen water generation device containing the hydrogen water generator of the first specific example is attached to a tap and water is fed at a predetermined flow rate (about 2 L / min). At each time point, 500 mL of hydrogen water was collected. The dissolved hydrogen concentration (ppb) of the collected sample water was measured with a dissolved hydrogen concentration meter (KM2100DH; Kyoei Electronics Research Laboratories). The dissolved ClO concentration was measured by a colorimetric method (DPD method) using diethyl-p-phenylenediamine (DPD) and a pH / ion meter (F-23; Horiba Seisakusho). The measurement results are shown in Table 1.

When the water flow was continued at a flow rate of about 2 L / min, the hydrogen concentration became 50 ppb or less. When the hydrogen concentration was measured again after stopping the water flow overnight (16 hours), it increased to about 700 ppb. This is because the raw water that had stopped inside the hydrogen water generator reacted with magnesium to generate hydrogen while the water flow was stopped.
It was found that hydrogen water having a high hydrogen concentration exceeding 500 ppb can be collected if the water flow is stopped.
The dissolved ClO concentration of the raw water was about 0.7 mg / L, but the dissolved ClO concentration of the collected hydrogen water was about 0.1 mg / L or less, and the water purification ability was also demonstrated.

Example 2
(1) Production of hydrogen water generator with water purification function A hydrogen water generator (cartridge) of a second specific example is shown in FIG. In FIG. 4, the description about the same part as FIG. 3 may be omitted.
A housing 31 having a sintered filter 32b at the bottom was prepared, and an activated carbon layer 34b made of fibrous activated carbon was disposed on the sintered filter 32b. 7.5 g of zeolite was uniformly spread thereon, and 5 g of metal magnesium was spread thereon to form a multilayer 37b composed of a metal magnesium layer 35b on the upstream side and a zeolite layer 36b on the downstream side. In the same manner, a multilayer 37a composed of a metal magnesium layer 35a on the upstream side and a zeolite layer 36a on the downstream side was formed. An activated carbon layer 34a made of fibrous activated carbon was disposed thereon. Further, an activated carbon layer 33 made of 16 g of granular activated carbon was formed thereon. Finally, the lid was covered with the sintered filter 32a to produce a hydrogen water generator of the second specific example.

(2) Measurement of hydrogen water generating capacity A hydrogen water generating device containing the hydrogen water generator of the second specific example is attached to a tap of water supply, and raw water is passed at a predetermined flow rate (about 2 L / min), At each time point, 500 mL of hydrogen water was collected. The dissolved hydrogen concentration (ppb) of the collected sample water was measured with a dissolved hydrogen concentration meter (KM2100DH; Kyoei Electronics Research Laboratories). The dissolved ClO concentration was measured by a colorimetric method (DPD method) using diethyl-p-phenylenediamine (DPD) and a pH / ion meter (F-23; Horiba Seisakusho). The measurement results are shown in Table 2.

When water flow was continued at a flow rate of about 2 L / min, the hydrogen concentration became about 50 to 100 ppb. When the total water flow rate was 196 L, after stopping water flow for 1 hour, when the hydrogen concentration was measured again, it increased to about 260 ppb. When the total water flow amount was 650 L, after stopping the water flow for a long time (64 hours), when the hydrogen concentration was measured again, it increased to about 250 ppb.
Note that the dissolved ClO concentration of the collected hydrogen water was approximately 0.1 mg / L or less, and the water purification ability was also exhibited.
The collected hydrogen water was alkaline with a pH of about 8 to 10 suitable for drinking.

Example 3
(1) Production of hydrogen water generator with water purification function A hydrogen water generator (cartridge) of a third specific example is shown in FIG. In FIG. 5, the description about the same part as FIG. 3 and FIG. 4 may be abbreviate | omitted.
A housing 31 having a sintered filter 32b at the bottom was prepared, and two layers of activated carbon layers 34a and 34b made of fibrous activated carbon were disposed on the sintered filter 32b. On top of that, two layers 37a and 37b composed of a metal magnesium layer and a zeolite layer were formed in the same manner as in Example 2. A non-woven fabric 38 (Nippon Vilene Co., Ltd.) was placed thereon. Further, an activated carbon layer 33 made of 16 g of granular activated carbon was formed thereon. Finally, the lid was covered with the sintered filter 32a to produce a hydrogen water generator of the third specific example.

(2) Measurement of hydrogen water generation capacity A hydrogen water generation device containing the hydrogen water generator of the third specific example is attached to a tap, and the raw water is passed at a predetermined flow rate (about 2 L / min). At each time point, 500 mL of hydrogen water was collected. The dissolved hydrogen concentration (ppb) of the collected sample water was measured with a dissolved hydrogen concentration meter (KM2100DH; Kyoei Electronics Research Laboratories). The dissolved ClO concentration was measured by a colorimetric method (DPD method) using diethyl-p-phenylenediamine (DPD) and a pH / ion meter (F-23; Horiba Seisakusho). Table 3 shows the measurement results.

When water was kept flowing at a flow rate of about 2 L / min, the hydrogen concentration became about 50 to 60 ppb. When the total water flow rate was 950 L, after stopping water flow for a long time (40 hours), when the hydrogen concentration was measured again, it increased to about 320 ppb. When the total water flow amount was 150 L, the hydrogen concentration was not sufficiently recovered even after the water flow was stopped for a long time (64 hours), probably because the system was not stable.
Note that the dissolved ClO concentration of the collected hydrogen water was approximately 0.1 mg / L or less, and the water purification ability was also exhibited.
The collected hydrogen water was alkaline with a pH of about 7 to 10 suitable for drinking.

Table 4 shows the measurement results when water was further passed through the above.
Here, the oxidation-reduction potential (ORP) in terms of H ₂ is further measured with a pH / ion meter (F-23; Horiba Seisakusho) and displayed on the basis of a standard hydrogen electrode.

  The ORP value obtained by the measurement is a value for the reference electrode used for the measurement. Therefore, when a standard hydrogen electrode (NHE) is used as a reference electrode in the following procedure in order to standardize a measurement value obtained using an Ag / AgCl inner electrode having 3.33 MKCl as an internal solution as a reference electrode Converted to the value of.

In the formula, E _NHE is an ORP measurement value using a standard hydrogen electrode (NHE) as a reference electrode, E is an ORP measurement value using 3.33 MKCl—Ag / AgCl as a reference electrode, and t is a measurement temperature (0 to 60 ° C.). is there.

When the system was stabilized, the hydrogen concentration was maintained at about 120 ppb or more due to intermittent water flow even at a flow rate of about 2 L / min. On the way, the hydrogen concentration was maintained at about 120 ppb or more even when the water flow rate was about 0.5 L / min. That is, it was found that hydrogen water having a sufficient concentration can be collected if water is intermittently passed even at a flow rate of about 2 L / min.
The collected hydrogen water was alkaline with a pH of about 8.5 to 9.5 suitable for drinking, and the ORP was 220 to 300 mV. The pH of tap water is 7.5 and the ORP is about 800 mV.

FIG. 9 is a graph showing the correlation between the ORP of water and pH. The higher the ORP value, the more water is oxidized, and the lower the ORP, the lower the value. The ORP decreases as the pH increases, and the upper and lower solid lines indicate the upper and lower limits of water. In addition, the area below the dotted line in the center is said to be a state of water good for the body such as natural water.
The tap water (black square) showed the upper limit of ORP at around pH 7. The ORP of purified water (black triangles) from which only chlorine was removed with activated carbon was slightly lower than that of raw water, and did not become a state of water that was considered good for the body.
On the other hand, the hydrogen water produced by the present invention (black circle) increased in pH as compared with the raw water, while the ORP greatly decreased and became below the dotted line, and the water was considered good for the body.

Furthermore, two layers of multiple layers 37a and 37b composed of a metal magnesium layer and a zeolite layer were formed thereon as in Example 2. Finally, the lid was covered with the sintered filter 32a to produce a hydrogen water generator of the fourth specific example.

(2) Measurement of hydrogen water generation capacity A hydrogen water generation device containing the hydrogen water generator of the fourth specific example is attached to a faucet, and the raw water is passed at a predetermined flow rate (about 2 L / min). At each time point, 500 mL of hydrogen water was collected. The dissolved hydrogen concentration (ppb) of the collected sample water was measured with a dissolved hydrogen concentration meter (KM2100DH; Kyoei Electronics Research Laboratories). The dissolved ClO concentration was measured by a colorimetric method (DPD method) using diethyl-p-phenylenediamine (DPD) and a pH / ion meter (F-23; Horiba Seisakusho). The redox potential (ORP) in terms of H ₂ is measured with a pH / ion meter (F-23; Horiba Seisakusho) and displayed on a standard hydrogen electrode basis. Table 5 shows the measurement results.

When the total water flow rate was 400 L, after stopping the water flow overnight (16 hours), when the hydrogen concentration was measured again, it increased to about 650 ppb. When water was continuously passed at a flow rate of about 2 L / min, the hydrogen concentration became about 40 to 70 ppb.
The collected hydrogen water was alkaline with a pH of about 7 to 10 suitable for drinking.

  Table 6 shows the measurement results when the water continuation and the water flow stop were further repeated in the above continuation, and each 500 mL was collected and the change in hydrogen concentration was examined.

  After stopping water flow overnight (16 hours), the hydrogen concentration was about 660 ppb. After collecting 500 mL, the hydrogen concentration dropped to 450 ppb. Here, after the water flow was stopped for 3 hours, when the hydrogen concentration was measured again, it recovered to about 690 ppb. Thereafter, when the collection of 500 mL of hydrogen water was repeated after stopping the water flow for 1 hour, the hydrogen concentration was maintained at 220 ppb or more. This is a value that can sufficiently achieve the purpose of beauty and health. FIG. 10 shows the relationship between the water passage stop time and the change in hydrogen concentration.

A mixture of 8 g of granular activated carbon and 5 g of magnesium metal was spread thereon to form a mixture layer 39b. Further, a zeolite layer 36a was formed thereon in the same manner, and a mixture layer 39a was formed thereon. Finally, the lid was covered with the sintered filter 32a to produce a hydrogen water generator of the fifth specific example.

Specifically, using a batch type cartridge (not shown), the effect of zeolite was examined by comparing the hydrogen water generating ability of metallic magnesium with and without zeolite. The bottom of the cartridge was filled with 13 g of metallic magnesium to produce a hydrogen water generator a for element testing. Similarly, 20 g of zeolite was uniformly spread on the bottom of the cartridge, and 13 g of metal magnesium was filled thereon to produce a hydrogen water generator b for element testing.

(2) Measurement of hydrogen water generation capacity Hydrogen water generator Hydrogen water generator a or hydrogen water generator b is housed in a dedicated hydrogen water generator (not shown), and 210 mL of tap water is poured from the upper part. The operation of collecting hydrogen water from the lower part was repeated. FIG. 11 shows the change over time in the dissolved hydrogen concentration of the hydrogen water collected at each generation time. The dissolved hydrogen concentration (ppb) was measured with a dissolved hydrogen concentration meter (KM2100DH; Kyoei Electronics Research Laboratories).
When the hydrogen water generator a containing only metallic magnesium was used, the dissolved hydrogen concentration of the collected hydrogen water varied greatly and was not stabilized. On the other hand, when the hydrogen water generator b in which metal magnesium and zeolite coexist was used, the fluctuation of the dissolved hydrogen concentration of the collected hydrogen water was small and converged to a constant value.
