Description

  The present invention relates to an electrolyzed water generating apparatus that generates electrolyzed water containing a hydrogen storage metal.

  Conventionally, various research and development have been conducted on electrolyzed water containing colloidal hydrogen storage metal colloids. For example, Patent Document 1 proposes a water treatment apparatus including an electrode pair to which an AC voltage is applied and an electrode pair to which a DC voltage is applied.

JP 2009-50774 A

  However, since the above apparatus requires an electrode pair for AC electrolysis in addition to a normal electrode pair for DC electrolysis, the cost of the apparatus is increased. In addition, since a circuit for applying an appropriate AC voltage to the electrode pair for AC electrolysis is required separately, an increase in the cost of the apparatus is inevitable.

  Further, in the apparatus shown in FIG. 4 of the same document, it is not possible to perform AC electrolysis and DC electrolysis at the same time because of the structure, so it takes time until desired electrolyzed water is generated. For this reason, it is not convenient and electrolyzed water containing a large amount of hydrogen storage metal colloid cannot be easily produced.

  The present invention has been devised in view of the above circumstances, and has as its main object to provide an electrolyzed water generating device that can easily generate electrolyzed water containing a large amount of hydrogen storage metal colloid with a simple configuration. .

  A first invention of the present invention is a first electrolysis chamber and a second electrolysis chamber for electrolyzing water, and an anode to which a DC voltage is applied, which is disposed in each electrolysis chamber of the first electrolysis chamber and the second electrolysis chamber. A feeder and a cathode feeder, a diaphragm disposed between the anode feeder and the cathode feeder, and dividing the electrolysis chamber into an anode chamber on the anode feeder side and a cathode chamber on the cathode feeder side; The surface of the anode feeder in the first electrolysis chamber is formed of a hydrogen storage metal and electrolyzed electrolyzed water electrolyzed in the anode chamber of the first electrolysis chamber. It has the 1st water channel led to the cathode room of 2 electrolysis rooms, It is characterized by the above-mentioned.

  In the electrolyzed water generating apparatus, it is preferable that an AC voltage is not applied to the anode feeder and the cathode feeder in the first electrolysis chamber.

  The electrolyzed water generating device preferably includes a second water channel that guides electrolyzed water electrolyzed in the cathode chamber of the first electrolysis chamber to the cathode chamber of the second electrolysis chamber.

  According to a second aspect of the present invention, there is provided an electrolyzed water generating method for generating electrolyzed water by electrolyzing supplied water in a plurality of electrolysis chambers including a first electrolysis chamber and a second electrolysis chamber. Each electrolytic chamber of the electrolysis chamber and the second electrolysis chamber is disposed between an anode feeder and a cathode feeder, and between the anode feeder and the cathode feeder, and each electrolytic chamber is disposed on the anode feeder side. A diaphragm that is divided into an anode chamber and a cathode chamber on the cathode feeder side, and the anode feeder in the first electrolysis chamber has a surface formed of a hydrogen storage metal, and the anode of the first electrolysis chamber Supplying water to the chamber and the cathode chamber; and applying a DC voltage to the anode feeder and the cathode feeder in the first electrolysis chamber to electrolyze water in the anode chamber and the cathode chamber And electrolyzed water generated in the anode chamber of the first electrolysis chamber Supplying a DC voltage to the anode feeder and the cathode feeder of the second electrolysis chamber; supplying the cathode chamber of the second electrolysis chamber with water; supplying water to the anode chamber of the second electrolysis chamber; And electrolyzing water in the anode chamber and the cathode chamber of the second electrolysis chamber.

  In the electrolyzed water generating device according to the first aspect of the invention, the surface of the anode feeder in the first electrolysis chamber is formed of a hydrogen storage metal. Therefore, during electrolysis, the hydrogen storage metal is ionized in the anode chamber of the first electrolysis chamber. To do. The ions of the hydrogen storage metal generated at this time are guided to the cathode chamber of the second electrolysis chamber through the first water channel together with the electrolyzed water electrolyzed in the anode chamber of the first electrolysis chamber. In the cathode chamber of the second electrolysis chamber, when the cathode power supply supplies electrons to the ions of the hydrogen storage metal, colloidal hydrogen storage metal is precipitated, and electrolyzed water containing a large amount of hydrogen storage metal colloid is generated. Generated.

  In addition, since the anode chamber and the cathode chamber are separated by the diaphragm in the first electrolysis chamber, the ions of the hydrogen storage metal generated in the cathode chamber of the first electrolysis chamber move to the cathode chamber of the second electrolysis chamber. There is no. Furthermore, since the anode chamber and the cathode chamber are separated by the diaphragm in the second electrolysis chamber, the hydrogen storage metal colloid generated in the cathode chamber does not move to the anode chamber. For this reason, the quantity of the hydrogen storage metal colloid contained in the electrolysis hydrogen water taken out from an apparatus increases easily. Furthermore, since electrolyzed water containing a large amount of hydrogen storage metal colloid is generated only by direct current electrolysis, the configuration of the apparatus is simple and the time required for generating electrolyzed water is shortened.

  In the electrolyzed water generating method of the second aspect of the invention, in the step of electrolyzing water in the anode chamber and the cathode chamber of the first electrolysis chamber, the hydrogen storage metal is ionized on the surface of the anode feeder in the first electrolysis chamber. The ions of the hydrogen storage metal generated at this time move to the cathode chamber together with the electrolyzed water in the step of supplying the electrolyzed water to the cathode chamber of the second electrolysis chamber. In the step of electrolyzing water in the anode chamber and the cathode chamber of the second electrolysis chamber, the cathode power supply supplies electrons to the ions of the hydrogen storage metal, so that the cathode chamber of the second electrolysis chamber has a colloidal shape. The hydrogen storage metal is precipitated, and electrolyzed water containing a large amount of hydrogen storage metal colloid is generated. Moreover, since electrolyzed water containing a large amount of hydrogen storage metal colloid is generated only by direct current electrolysis, the steps required for generating electrolyzed water are simplified and the time is shortened.

It is a figure which shows the flow-path structure of the modification of the electrolyzed water generating apparatus of FIG. It is a figure which shows the flow-path structure of another modification of the electrolyzed water generating apparatus of FIG.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of an electrolyzed water generating apparatus 1 of the present embodiment. FIG. 2 shows the electrical configuration of the electrolyzed water generator 1. The electrolyzed water generating apparatus 1 includes a plurality of electrolyzers 3 and 4 and a control unit 8 that controls each part of the electrolyzed water generating apparatus 1.

  Inside the electrolytic cell 3, an electrolysis chamber 30 (first electrolysis chamber) to which water to be electrolyzed is supplied is formed. The electrolysis chamber 30 is supplied with raw water before electrolysis. As the raw water, tap water is generally used, but well water, ground water, and the like can be used. A water purification cartridge for purifying water supplied to the electrolysis chamber 30 may be provided on the upstream side of the electrolysis chamber 30.

  The electrolysis chamber 30 accommodates first and second power feeding bodies 31 and 32 having different polarities, and a diaphragm 33 that separates the electrolysis chamber 30.

  The first power supply body 31 and the second power supply body 32 are disposed to face each other in the electrolysis chamber 30. The surface of the 1st electric power feeding body 31 and the 2nd electric power feeding body 32 is formed with the hydrogen storage metal. Examples of the hydrogen storage metal include platinum, palladium, vanadium, magnesium, and zirconium, and alloys including these as components are also included. In the present embodiment, a platinum plating layer is formed on the surfaces of the first power feeding body 31 and the second power feeding body 32.

  The diaphragm 33 is disposed between the first power feeding body 31 and the second power feeding body 32. The diaphragm 33 divides the electrolysis chamber 30 into a first electrode chamber 30a on the first power feeder 31 side and a second electrode chamber 30b on the second power feeder 32 side. The diaphragm 33 is made of, for example, a polytetrafluoroethylene (PTFE) hydrophilic film. When a DC voltage is applied between the first power supply body 31 and the second power supply body 32, water is electrolyzed in the electrolysis chamber 30 to obtain electrolyzed water.

  The configuration of the electrolytic cell 4 is the same as that of the electrolytic cell 3. That is, an electrolysis chamber 40 (second electrolysis chamber) is formed inside the electrolytic cell 4, and the electrolysis chamber 40 is divided into a first feeding body 41 and a second feeding body 42 having different polarities, and the electrolysis chamber 40. A diaphragm 43 is accommodated.

  The 1st electric power feeder 41 and the 2nd electric power feeder 42 are arrange | positioned facing each other, and those surfaces are formed with the hydrogen storage metal. The diaphragm 43 is disposed between the first power supply body 41 and the second power supply body 42, and the electrolysis chamber 40 includes a first electrode chamber 40 a on the first power supply body 41 side and a second pole on the second power supply body 42 side. It is divided into the chamber 40b. The diaphragm 43 is made of, for example, a polytetrafluoroethylene hydrophilic film in the same manner as the diaphragm 33.

  For example, in the state shown in FIG. 1, positive charge is charged in the first power feeding body 31 of the electrolytic cell 3, and the first electrode chamber 30 a functions as an anode chamber. On the other hand, negative charge is charged in the second power feeding body 32, and the second electrode chamber 30b functions as a cathode chamber. As a result, reducing electrolytic hydrogen water in which the generated hydrogen gas is dissolved is generated in the second electrode chamber 30b, and electrolytic acid water in which the generated oxygen gas is dissolved in the first electrode chamber 30a.

  On the other hand, positive charge is charged in the first power supply body 41 of the electrolytic cell 4, and the first electrode chamber 40a functions as an anode chamber. On the other hand, negative charge is charged in the second power feeding body 42, and the second electrode chamber 40b functions as a cathode chamber. Thus, reducing electrolytic hydrogen water in which the generated hydrogen gas is dissolved is generated in the second electrode chamber 40b, and electrolytic acid water in which the generated oxygen gas is dissolved in the first electrode chamber 40a.

  As shown in FIG. 2, the first power supply body 31 and the second power supply body 32 of the electrolytic cell 3 and the control means 8 are connected via a current supply line 34. In the current supply line 34 between the first power feeder 31 and the control means 8, a current detection means 34a is provided. The current detection unit 34 a may be provided in a current supply line between the second power feeder 32 and the control unit 8. The current detection unit 34 a detects a direct current (electrolytic current) supplied to the first power supply body 31 and the second power supply body 32, and outputs an electric signal corresponding to the value to the control means 8.

  Similarly, the first power supply body 41 and the second power supply body 42 of the electrolytic cell 4 and the control means 8 are connected via a current supply line 44. The current supply line 44 is provided with current detection means 44a. The current detection unit 44 a detects a direct current (electrolytic current) supplied to the first power supply body 41 and the second power supply body 42, and outputs an electric signal corresponding to the value to the control means 8.

  The control unit 8 includes, for example, a CPU (Central Processing Unit) that executes various arithmetic processes, information processing, and the like, a program that controls the operation of the CPU, and a memory that stores various information. Various functions of the control means 8 are realized by a CPU, a memory, and a program.

  For example, the control unit 8 controls the DC voltage (electrolytic voltage) applied to the first power supply body 31 and the second power supply body 32 based on the electrical signal output from the current detection unit 34a. More specifically, the control means 8 controls the first power supply 31 and the first power supply 31 so that the electrolytic current detected by the current detection means 34a becomes a desired value according to the dissolved hydrogen concentration set by the user or the like. 2. The voltage applied to the power feeder 32 is feedback controlled. For example, when the electrolysis current is excessive, the control unit 8 decreases the voltage, and when the electrolysis current is excessive, the control unit 8 increases the voltage. Thereby, the electrolysis current supplied to the first power supply 31 and the second power supply 32 is appropriately controlled, and hydrogen water having a desired dissolved hydrogen concentration is generated in the electrolysis chamber 30.

  Similarly, the control means 8 controls the DC voltage applied to the first power supply body 41 and the second power supply body 42 based on the electrical signal output from the current detection means 44a. Thereby, the electrolysis current supplied to the first power supply body 41 and the second power supply body 42 is appropriately controlled, and hydrogen water having a desired dissolved hydrogen concentration is generated in the electrolysis chamber 40.

  The polarities of the first power feeder 31 and the second power feeder 32 are controlled by the control means 8. That is, the control unit 8 functions as a polarity switching unit that switches the polarities of the first power supply 31 and the second power supply 32. When the control unit 8 appropriately switches the polarities of the first power supply body 31 and the second power supply body 32, the opportunity for the first power supply body 31 and the second power supply body 32 to function as an anode chamber or a cathode chamber is equalized. Thereby, adhesion of the scale to the 1st electric power feeder 31 and the 2nd electric power feeder 32 grade | etc., Is suppressed.

  Similarly, the polarities of the first power supply body 41 and the second power supply body 42 are controlled by the control means 8. By the control means 8 appropriately switching the polarities of the first power feeding body 41 and the second power feeding body 42, the adhesion of the scale to the first power feeding body 41, the second power feeding body 42 and the like is suppressed.

  In the electrolyzed water generating apparatus 1, the first power feeding body 31 and the first power feeding body 41 are controlled to have the same polarity, and the second power feeding body 32 and the second power feeding body 42 have the same polarity. To be controlled. Hereinafter, in this specification, unless otherwise specified, as shown in FIG. 1, the first power feeder 31 and the first power feeder 41 function as the anode power feeder, and the second power feeder 32 and the second power feeder 32. Although the case where the power feeding body 42 functions as a cathode power feeding body will be described, the same applies to the case where the polarities of the first power feeding bodies 31 and 41 and the second power feeding bodies 32 and 42 are interchanged with each other (a diagram to be described later). The same applies to 4, 5).

  As shown in FIG. 1, the electrolyzed water generating apparatus 1 includes a water inlet 2 provided on the upstream side of the electrolyzer 3, an intermediate portion 5 provided between the electrolyzer 3 and the electrolyzer 4, and electrolysis And a water discharge section 6 provided on the downstream side of the tank 4.

  The water inlet 2 has a water supply channel 21, a flow rate sensor 22, a branching portion 23, a flow rate adjustment valve 25, and the like. The water supply path 21 supplies water to be electrolyzed to the electrolysis chamber 30. The flow sensor 22 is provided in the water supply channel 21. The flow rate sensor 22 periodically detects the flow rate per unit time of water supplied to the electrolysis chamber 30 (hereinafter sometimes simply referred to as “flow rate”) F, and outputs a signal corresponding to that value to the control means 8. Output to.

  The branch part 23 branches the water supply path 21 into the water supply paths 21a and 21b. The flow regulating valve 25 connects the water supply channels 21a and 21b to the first electrode chamber 30a or the second electrode chamber 30b. The flow rate of water supplied to the first electrode chamber 30 a and the second electrode chamber 30 b is adjusted by the flow rate adjusting valve 25 under the control of the control means 8. In the present embodiment, since the flow sensor 22 is provided on the upstream side of the branch portion 23, the flow rate of water supplied to the first electrode chamber 30a and the flow rate of water supplied to the second electrode chamber 30b are The total, that is, the flow rate F of water supplied to the electrolysis chamber 30 is detected.

  The intermediate part 5 includes intermediate water channels 51 and 52. The intermediate water channel 51 (first water channel) allows the first electrode chamber 30a of the electrolytic cell 3 and the second electrode chamber 40b of the electrolytic cell 4 to communicate with each other, and the electrolyzed water electrolyzed in the first electrode chamber 30a is the second electrode. Lead to chamber 40b. The intermediate water channel 52 communicates the second electrode chamber 30b of the electrolytic cell 3 and the first electrode chamber 40a of the electrolytic cell 4, and guides the electrolyzed water electrolyzed in the second electrode chamber 30b to the first electrode chamber 40a.

  The water outlet 6 has a first water outlet 61, a second water outlet 62, and a flow path switching valve 65.

  In FIG. 1, the first outlet channel 61 functions as a cathode channel for taking out the electrolyzed water (that is, electrolyzed hydrogen water) generated in the cathode chamber of the first and second electrode chambers 40a and 40b. ing. On the other hand, the second water discharge channel 62 functions as an anode water channel for taking out the electrolyzed water generated in the anode chamber of the first and second electrode chambers 40a and 40b.

  The flow path switching valve 65 is provided downstream of the electrolytic cell 4. The flow path switching valve 65 functions as a flow path switching means for switching the connection between the first and second polar chambers 40a and 40b and the first and second outlet channels 61 and 62.

  In the present embodiment, the control unit 8 switches the polarity of the first power supply body 31, the second power supply body 32, the first power supply body 41, and the second power supply body 42 and the flow path switching by the flow path switching valve 65. By synchronizing, the electrolyzed water selected by the user (for example, electrolyzed hydrogen water in FIG. 1) can always be discharged from one water channel (in FIG. 1, the first water outlet 61).

  In switching the polarities of the first power feeding body 31, the second power feeding body 32, the first power feeding body 41, and the second power feeding body 42, the control means 8 interlocks the flow rate adjusting valve 25 and the flow path switching valve 65. It is desirable to operate in the form of Thereby, before and after switching the polarity, the water supply to the polar chamber connected to the second drainage channel 62 is ensured while sufficiently supplying the water to the polar chamber connected to the first drainage channel 61. It is possible to suppress the supply amount and to effectively use water.

  For example, as described in Japanese Patent No. 5809208, the flow rate adjusting valve 25 and the flow path switching valve 65 are preferably integrally formed and driven in conjunction with a single motor. That is, the flow rate adjustment valve 25 and the flow path switching valve 65 are configured by a cylindrical outer cylinder and an inner cylinder. A flow path constituting the flow rate adjustment valve 25 and the flow path switching valve 65 is formed inside and outside the inner cylinder, and each flow path is in accordance with the operating state of the flow rate adjustment valve 25 and the flow path switching valve 65. It is configured to cross appropriately. Such a valve device is referred to as a “double auto change cross line valve”, contributes to the simplification of the configuration and control of the electrolyzed water generating device 1, and further increases the commercial value of the electrolyzed water generating device 1.

  In the electrolyzed water generating apparatus 1, the surface of the first power feeding body 31 of the electrolysis chamber 30 is formed of a hydrogen storage metal. Therefore, during electrolysis, the hydrogen storage metal is ionized in the first electrode chamber 30 a of the electrolysis chamber 30. To do. The ions of the hydrogen storage metal generated at this time are guided to the second electrode chamber 40b of the electrolysis chamber 40 through the intermediate water channel 51 together with the electrolyzed water electrolyzed in the first electrode chamber 30a of the electrolysis chamber 30. In the second electrode chamber 40b of the electrolysis chamber 40, the second power feeding body 42 supplies electrons to the ions of the hydrogen storage metal, so that colloidal hydrogen storage metal is deposited and contains a large amount of hydrogen storage metal colloid. Electrolyzed water is generated.

  Further, since the first electrode chamber 30a and the second electrode chamber 30b are separated from each other by the diaphragm 33 in the electrolysis chamber 30, the ions of the hydrogen storage metal generated in the first electrode chamber 30a are separated from the second electrode chamber 30b and the second electrode chamber 30b. There is no movement to the unipolar chamber 40a. Furthermore, since the first electrode chamber 40a and the second electrode chamber 40b are separated by the diaphragm 43 in the electrolysis chamber 40, the hydrogen storage metal colloid generated in the second electrode chamber 40b moves to the first electrode chamber 40a. There is nothing. For this reason, the quantity of the hydrogen storage metal colloid contained in the electrolysis hydrogen water taken out from the electrolysis water production | generation apparatus 1 increases easily. Furthermore, since electrolyzed water containing a large amount of hydrogen storage metal colloid is generated only by direct current electrolysis, the configuration of the electrolyzed water generating apparatus 1 is simple and the time required for generating electrolyzed water is shortened.

  As shown in FIG. 1, in the electrolyzed water generating device 1, a filter 53 may be provided in the intermediate water channel 51. The filter 53 removes hypochlorous acid contained in the electrolyzed water taken out from the first electrode chamber 30a. The filter 53 is effective when tap water containing calcium hypochlorite is used as raw water. The filter 53 may be provided in the first water discharge channel 61.

  FIG. 3 shows an embodiment of a treatment procedure of an electrolyzed water generation method for electrolyzing supplied water using a plurality of electrolysis chambers 30 and 40 to generate electrolyzed water containing a large amount of hydrogen storage metal colloids. It is a flowchart to show.

  When water is supplied to the first electrode chamber 30a and the second electrode chamber 30b of the electrolysis chamber 30 (S1), when a DC voltage is applied between the first power supply body 31 and the second power supply body 32, The water in the first electrode chamber 30a and the second electrode chamber 30b is electrolyzed (S2). As a result, the anode-side first power feeder 31 takes electrons from the surrounding water and generates oxidized water. At this time, the hydrogen storage metal loses electrons and ionizes on the surface of the first power feeder 31. That is, the oxidized water generated in S2 contains ions of the hydrogen storage metal.

  Next, the oxidized water generated in the first electrode chamber 30a is supplied to the second electrode chamber 40b of the electrolytic cell 4 through the intermediate water channel 51 and is moved to the vicinity of the second power supply body 42 on the cathode side (S3). ). Along with this, ions of the hydrogen storage metal are also moved to the periphery of the second power feeder 42. Further, the reduced water generated in the second electrode chamber 30b is supplied to the first electrode chamber 40a of the electrolytic cell 4 through the intermediate water channel 52 (S4). In S4, water (for example, raw water flowing through the water supply channel 21) other than the oxidized water generated in the second electrode chamber 30b may be supplied. By S3 and S4, the first electrode chamber 40a and the second electrode chamber 40b of the electrolytic cell 4 are filled with water to be electrolyzed.

  And if a DC voltage is applied between the 1st electric power feeder 41 and the 2nd electric power feeder 42, the water in the 1st polar chamber 40a and the 2nd polar chamber 40b will be electrolyzed (S5). Thereby, the 2nd electric power feeder 42 supplies an electron to peripheral oxidation water, and reduces oxidation water. At this time, the ions of the hydrogen storage metal receive electrons from the second power supply body 42, become minute hydrogen storage metal colloids, precipitate in the reduced water, and generate electrolyzed water containing a large amount of hydrogen storage metal colloids. .

  FIG. 4 shows an electrolyzed water generating apparatus 1A that is a modification of the electrolyzed water generating apparatus 1 shown in FIG. Regarding the portion of the electrolyzed water generating apparatus 1A that is not described below, the configuration of the electrolyzed water generating apparatus 1 described above can be employed.

  The electrolyzed water generating device 1 </ b> A differs from the electrolyzed water generating device 1 in that the electrolyzed water generating device 1 </ b> A includes a flow path switching valve 55 in the intermediate portion 5. The flow path switching valve 55 includes a first polar chamber 30a through the intermediate water channel 56a, a second polar chamber 30b through the intermediate water channel 56b, a first polar chamber 40a through the intermediate water channel 57a, and a second polar chamber 40b through the intermediate water channel 57b. Each communicates. The flow path switching valve 55 functions as a flow path switching means for switching the connection destination of the first electrode chamber 30a and the second electrode chamber 30b of the electrolytic cell 3 to the first electrode chamber 40a or the second electrode chamber 40b of the electrolytic cell 4. To do.

  The flow path switching valve 55 is controlled by the control means 8. The control unit 8 synchronizes the switching of the polarities of the first power feeding body 31, the second power feeding body 32, the first power feeding body 41 and the second power feeding body 42 with the switching of the flow path by the flow path switching valve 55. Accordingly, the flow path switching valve 55 operates in synchronization with the flow rate adjustment valve 25 and the flow path switching valve 65.

  In the state shown in FIG. 4, the intermediate water channels 56 a and 56 b are communicated with the intermediate water channel 57 b by the flow path switching valve 55. That is, the first electrode chamber 30 a and the second electrode chamber 30 b of the electrolytic cell 3 are connected to the second electrode chamber 40 b of the electrolytic cell 4. In this case, the intermediate water channel 56a and the intermediate water channel 57b function as a first water channel that guides the electrolyzed water electrolyzed in the first polar chamber 30a to the second polar chamber 40b, and the intermediate water channel 56b and the intermediate water channel 57b are the second water channel. It functions as a second water channel that guides the electrolyzed water electrolyzed in the polar chamber 30b to the second polar chamber 40b. Then, raw water is separately supplied to the first electrode chamber 40 a of the electrolytic cell 4 from a water channel (not shown) branched from the water supply channel 21.

  In the electrolyzed water generating apparatus 1 </ b> A, the electrolyzed hydrogen water that is generated in the second electrode chamber 30 b of the electrolyzer 3 and in which hydrogen gas has already dissolved is supplied to the second electrode chamber 40 b of the electrolyzer 4. The electrolytic hydrogen water is further increased in dissolved hydrogen concentration by electrolysis in the second electrode chamber 40b. Therefore, according to the electrolyzed water generating apparatus 1A, electrolyzed water having a high dissolved hydrogen concentration and rich in hydrogen storage metal colloids can be generated.

  When the first power feeders 31 and 41 are switched to the cathode and the second power feeders 32 and 42 are switched to the anode, the intermediate water passages 56a and 56b are communicated with the intermediate water passage 57a by the flow passage switching valve 55, and the electrolytic cell 3 The first electrode chamber 30 a and the second electrode chamber 30 b are connected to the first electrode chamber 40 a of the electrolytic cell 4. In addition, raw water is separately supplied from the water supply channel 21 to the second electrode chamber 40b. Thereby, similarly to the above, electrolyzed water having a high dissolved hydrogen concentration and rich in hydrogen storage metal colloids can be generated.

  FIG. 5 shows an electrolyzed water generating device 1B which is another modified example of the electrolyzed water generating device 1 shown in FIG. About the part which is not demonstrated below among the electrolyzed water generating apparatuses 1B, the structure of the electrolyzed water generating apparatus 1 mentioned above can be employ | adopted.

  The electrolyzed water generating device 1 </ b> B is different from the electrolyzed water generating device 1 in that the second water discharge channel 62 is connected to the intermediate water channel 51.

  In the electrolyzed water generating apparatus 1 </ b> B, electrolyzed water that is generated in the first electrode chamber 40 a of the electrolyzer 4 and contains hydrogen storage metal ions is supplied to the second electrode chamber 40 b of the electrolyzer 4. The electrolyzed water is also electrolyzed hydrogen water in which hydrogen gas already generated in the second electrode chamber 30b of the electrolytic cell 3 is dissolved. Therefore, according to the electrolyzed water generating apparatus 1B, electrolyzed water having a high dissolved hydrogen concentration and rich in hydrogen storage metal colloids can be generated.

  In addition, the electrolyzed water generating method shown in FIG. 3 can be implemented by the electrolyzed water generating device 1A and the electrolyzed water generating device 1B in addition to the electrolyzed water generating device 1.

  As mentioned above, although the electrolyzed water generating apparatus 1 etc. of this invention were demonstrated in detail, this invention is changed and implemented in various aspects, without being limited to said specific embodiment. That is, the electrolyzed water generating apparatus 1 includes at least an electrolysis chamber 30 and an electrolysis chamber 40 that electrolyze water, and a first power supply body 31 and a second power supply body 32 that are disposed in the electrolysis chamber 30 and to which a DC voltage is applied. The electrolysis chamber 30 is disposed between the first power supply body 41 and the second power supply body 42 and the first power supply body 31 and the second power supply body 32, which are arranged in the electrolysis chamber 40 and to which a DC voltage is applied. The diaphragm 33 is divided between the first electrode chamber 30a on the first power supply body 31 side and the second electrode chamber 30b on the second power supply body 32 side, and is disposed between the first power supply body 41 and the second power supply body 42. And a diaphragm 43 that divides the electrolysis chamber 40 into a first electrode chamber 40a on the first power supply body 41 side and a second electrode chamber 40b on the second power supply body 42 side, and the first power supply body 31 of the electrolysis chamber 30 is provided. The surface of the electrode is formed of hydrogen storage metal and electrolyzed electrolyzed water electrolyzed in the first electrode chamber 30a of the electrolysis chamber 30. It may be composed to have an intermediate water channel 51 that leads to the second electrode chamber 40b of the chamber 40.

  In the present electrolyzed water generating apparatus 1 and the like, the polarities of the first power feeding body 31 and the second power feeding body 32 are configured to be switchable. Therefore, the surfaces of the first power feeding body 31 and the second power feeding body 32 are hydrogen storage metals. Is formed by. However, in the configuration in which the polarity switching is not performed, only the surface of the anode power feeding body may be formed of a hydrogen storage metal.
