[0006] That is, in the anode, magnesium ions (Mg 2+However, this thinning does not occur uniformly throughout the anode, but rather occurs first in the vicinity of the conductor.

[0007] When the anode portion is locally thinned in the vicinity of the conductor in this manner, the remaining unthinned portions are prematurely detached from the conductor, making it impossible to proceed with electrolysis while leaving much of the electrode effective, and making it difficult to obtain a sufficient service life.

[0008] In view of the above circumstances, an object of the present invention is to provide a water alkalinization apparatus that can extend its service life. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the water alkalinization device of the present invention is a water alkalinization device that alkalizes the water quality of an electrolyte stored inside an electrolytic cell by applying a voltage from a power supply unit between electrodes at least partially immersed in the electrolyte stored inside the electrolytic cell to generate a basic liquid, and is characterized in that at least the anode of the electrode comprises a collector rod that is electrically connected to the power supply unit, an electrode component that is in electrical contact with the collector rod, and a cylindrical body that is formed with a plurality of holes and that houses the collector rod and the electrode component.

[Figure 2] FIG. 2 is an explanatory diagram showing a state in which electrolysis of tap water has progressed in the water alkalinization device shown in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the water alkalizing device according to the present invention will be described in detail below with reference to the accompanying drawings.

[0020] 1 is an explanatory diagram showing a schematic configuration of a water alkalizing device according to an embodiment of the present invention. The water alkalizing device 1 shown here includes an electrolytic cell 10.

[0021] The electrolytic cell 10 stores an electrolyte, which in this embodiment stores tap water 11. An electrode 20 is disposed in the electrolytic cell 10 with a portion of the electrode 20 immersed in the tap water 11.

[0022] The electrode 20 has a first electrode portion 21 and a second electrode portion 22 that are arranged in a spaced apart manner, and each is electrically connected to a power supply portion 16 via a conductor 15 .

[0023] The first electrode section 21 constituting the electrode 20 is configured to include a first filter cylinder 211 , a first current collecting rod 212 and a first electrode component 213 .

[0024] The first filter cylinder 211 is a cylindrical body with the vertical direction as the longitudinal direction. More specifically, the first filter cylinder 211 is a cylindrical body having a tapered shape such that the cross-sectional area of the lower end portion gradually decreases as it extends downward. The first filter cylinder 211 is made of a mesh material made of a conductive material such as metal, and has a plurality of holes 211a formed therein.

[0025] The first current collecting rod 212 is a rod-shaped body extending in the vertical direction, and has a vertical dimension that is approximately equal to the vertical dimension of the first filter cylinder 211. The first current collecting rod 212 is made of a conductive material, and extends along the central axis of the first filter cylinder 211 from the lower end portion to the upper end portion of the first filter cylinder 211. The upper end portion of such a first current collecting rod 212 is electrically connected to the conductive wire 15, and the lower end portion is in contact with the first filter cylinder 211.

[0026] The first electrode constituent material 213 is housed in the first filter cylinder 211 together with the first current collecting rod 212. This first electrode constituent material 213 is composed of a plurality of first electrode components 213a containing a metal included in the second element, and in this embodiment, is composed of a plurality of first electrode components 213a containing magnesium.

[0027] The plurality of first electrode components 213a are particulate, and the outer diameter (maximum width) thereof is larger than the width of the holes 211a. That is, the first filter cylinder 211 has a size in which the plurality of holes 211a are smaller than the outer diameter (maximum width) of the first electrode components 213a and allow the tap water 11 to pass through.

[0028] The second electrode part 22 constituting the electrode 20 has the same configuration as the first electrode part 21, and is composed of a second filter cylinder 221, a second current collecting rod 222 and a second electrode component 223.

[0029] The second filter cylinder 221 is a cylindrical body with the vertical direction as the longitudinal direction. More specifically, the second filter cylinder 221 is a cylindrical body having a tapered shape such that the cross-sectional area of the lower end portion gradually decreases as it extends downward. The second filter cylinder 221 is made of a mesh material made of a conductive material such as metal, and has a plurality of holes 221a formed therein.

[0030] The second current collecting rod 222 is a rod-shaped body extending in the vertical direction, and has a vertical dimension that is approximately equal to the vertical dimension of the second filter cylinder 221. The second current collecting rod 222 is made of a conductive material, and extends along the central axis of the second filter cylinder 221 from the lower end portion to the upper end portion of the second filter cylinder 221. The upper end portion of such second current collecting rod 222 is electrically connected to the conductive wire 15, and the lower end portion is in contact with the second filter cylinder 221.

[0031] The second electrode component 223 is housed in the second filter cylinder 221 together with the second current collecting rod 222. The second electrode component 223 is composed of a plurality of second electrode components 223a containing a metal included in the second element, and in this embodiment, is composed of a plurality of second electrode components 223a containing magnesium.

[0032] The plurality of second electrode components 223a are particulate, and the outer diameter (maximum width) thereof is larger than the width of the holes 221a. That is, the second filter cylinder 221 has a size in which the plurality of holes 221a are smaller than the outer diameter (maximum width) of the second electrode components 223a and allow the tap water 11 to pass through.

[0033] The power supply unit 16 applies a DC voltage (e.g., DC 24 V) between the electrodes 20. In response to a command given from a control unit 30 that comprehensively controls the operation of the water alkalinization device 1, the power supply unit 16 applies a DC voltage between the electrodes 20 so that the first electrode unit 21 serves as an anode and the second electrode unit 22 serves as a cathode.

[0034] The water alkalizing device 1 having the above-described configuration produces alkaline water from tap water 11 stored in the electrolytic cell 10 and alkalizes the water in the following manner.

[0035] In response to a command from the control unit 30, the power supply unit 16 applies a voltage between the electrodes 20, with the first electrode unit 21 serving as an anode and the second electrode unit 22 serving as a cathode.

[0036] In the first electrode unit 21, the first current collecting rod 212 is electrically connected to the conducting wire 15, and a part of the first filter cylinder 211 is in contact with the first current collecting rod 212, so the first filter cylinder 211 is also in an electrically conductive state. Moreover, the first electrode constituent material 213 is in an electrically conductive state because a part of the first electrode constituent elements 213a is in contact with the first current collecting rod 212 and the first filter cylinder 211.

[0037] In the second electrode section 22, the second current collecting rod 222 is electrically connected to the conducting wire 15, and a part of the second filter cylinder 221 is in contact with the second current collecting rod 222, so the second filter cylinder 221 is also in an electrically conductive state. Moreover, the second electrode constituent material 223 is in an electrically conductive state because a part of the second electrode constituent elements 223a is in contact with the second current collecting rod 222 and the second filter cylinder 221.

[0038] As a result, the water alkalinization device 1 electrolyzes the tap water 11, and an electrolytic reaction of magnesium occurs at the first electrode portion 21 as shown in the following formula (1), and a reaction occurs at the second electrode portion 22 as shown in the following formula (2).

[0039] Formula (1) Mg→Mg 2+ +2e - Formula (2) 2H2O+2e - →H2+2OH -

[0040] As a result, hydroxide ions are generated at the second electrode portion 22, and the quality of the tap water 11 can be made alkaline.

[0041] In the first electrode unit 21, the first electrode constituent material 213 dissolves and is reduced in thickness due to the reaction of the above formula (1). However, since the first electrode constituent material 213 is housed in the first filter cylinder 211, as shown in Fig. 2, even if a portion of the first electrode constituent material 213 is reduced in thickness, electrical continuity between the first current collecting rod 212 and the first filter cylinder 211 is ensured, and the first electrode unit 21 can continue to function as the first electrode unit 21 and electrolysis of tap water 11.

[0042] As described above, in the water alkaline generation device 1 according to the embodiment of the present invention, the first electrode unit 21, which constitutes the anode of the electrode 20, is housed in the first filter cylinder 211 with the first electrode constituent material 23 electrically connected to the first current collector rod 212, which is electrically connected to the power supply unit 16. Therefore, even if the first electrode constituent material 23 dissolves and is reduced in thickness due to electrolysis of the tap water 11 in the electrolytic cell 10, the first electrode unit 21 can continue to function as an anode by being housed in the first filter cylinder 211 while maintaining electrical connection with the first current collector rod 212. Therefore, the first electrode unit 21 can function as an anode until the first electrode constituent material 23 disappears from the first filter cylinder 211, thereby extending the service life.

[0043] According to the water alkalinization device 1, since the first filter cylinder 211 is made of a conductive material, the first filter cylinder 211 can also function as a current collecting member, thereby promoting the electrolytic reaction of the first electrode component 23.

[0044] According to the water alkalinization device 1, the first filter cylinder 211 has a cylindrical shape with a tapered lower end, so that the thinned first electrode component 23 (first electrode component 23a) can be concentrated and accommodated so that it is in contact with the first collector rod 212, thereby maintaining a good electrolytic reaction of the first electrode component 23 even when the first electrode component 23 has been thinned.

[0045] Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this and various modifications can be made.

[0046] In the above-described embodiment, the second electrode portion 22 includes a second filter cylinder 221, a second current collecting rod 222, and a second electrode component 223, and has the same configuration as the first electrode portion 21. However, in the present invention, the second electrode portion forming the cathode may be made of a conductive material such as SUS or graphite.

[0047] In the above-described embodiment, the first electrode component 213a and the second electrode component 223a are in a particulate form, but in the present invention, they may be in a thin, flaky form, so-called flake form. Also, the electrode constituent material may be a mixture of particulate electrode components and flake electrode components.

[0048] In the above-described embodiment, the first electrode constituent material 213 etc. is configured as an assembly of the first electrode components 213a etc., but in the present invention, the electrode constituent material may be in the form of a flat plate. In this case, as in the conventional case, there is a risk that the thickness of the conductive wire will be reduced near the conductive wire and that the conductive wire will fall off. However, since the conductive wire is housed in a cylindrical body, the electrical connection as a current collecting rod is maintained, and the electrolytic reaction can be continued.

[0049] In the above-described embodiment, the first filter cylinder 211 and the second filter cylinder 221 are formed from a conductive material, but in the present invention, the cylindrical body may be formed from a non-conductive material such as ceramics.

[0050] Although not mentioned in the above-described embodiment, in the present invention, the control unit 30 may alternate the polarity of the voltage applied between the electrodes 20 at predetermined time intervals. In this way, one of the first electrode unit 21 and the second electrode unit 22 alternates as the anode, and the other alternates as the cathode. Hydroxide ions are generated at the cathode, thereby continuously alkalizing the tap water 11, and the anode thinning can alternately occur between the first electrode unit 21 and the second electrode unit 22, thereby extending the service life.

[0051] The configurations illustrated in the above-described embodiments are merely functional schematics and are not necessarily physically configured as shown. In other words, the distribution and integration of each device and component is not limited to that illustrated, and all or part of them can be functionally or physically distributed and integrated in any unit depending on various usage situations, etc. [Explanation of symbols]
