It is expected that the reducing electrolytic water generated in the cathode compartment of the electrolytic water producing device exerts an excellent effect for the improvement of gastrointestinal symptoms. Recently, the electrolytic water containing dissolved hydrogen gas produced in the cathode chamber by the electrolysis has attracted attention as being suitable for the removal of active oxygen.

Patent Document 1: Japanese Patent No. 5639724 In the electrolytic water producing apparatus described in Patent Document 1, the first convex portion disposed on the inner surface of the first case piece of the electrolytic bath is in contact with the anode power source, and the second convex portion disposed on the inner surface of the second case piece is in contact with the negative electrode power source .

However, in order to increase the dissolved hydrogen concentration of the electrolytic water, it is necessary to increase the amount of hydrogen gas generated in the electrolytic cell and efficiently dissolve the generated hydrogen gas in the electrolytic water. Since the generation amount of the hydrogen gas depends on the electrolytic current supplied to each class, it is necessary to increase the electrolytic current in order to generate a large amount of hydrogen gas in the electrolytic bath. In order to increase the electrolytic current, it is important to increase the electrolytic voltage applied to each class or to suppress the electrical resistance between the diaphragm and each class.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Fig. 1 shows a schematic configuration of the electrolytic water producing apparatus 1 of the present embodiment. The electrolytic water producing apparatus 1 can be used for the production of water for beverage and cooking at home and for the production of a dialysis liquid for hemodialysis.

The electrolytic water producing apparatus 1 includes an electrolytic bath 4 in which an electrolytic chamber 40 to which electrolyzed water is supplied is formed, and a cathode current collector 41 and a cathode A feeder 42 and a diaphragm 43 disposed between the positive electrode feeder 41 and the negative electrode feeder 42. Another electrolytic bath may be provided on the upstream side or the downstream side of the electrolytic bath 4. [ Further, another electrolytic bath may be provided in parallel with the electrolytic bath 4. The same configuration as that of the electrolytic bath 4 can be applied to the electrolytic bath separately provided.

The diaphragm 43 divides the electrolytic chamber 40 into an anode chamber 40A on the anode current collector 41 side and a cathode chamber 40B on the cathode current collector 42 side. Water is supplied to both the anode chamber 40A and the cathode chamber 40B of the electrolysis chamber 40 and the DC voltage is applied to the anode power supply 41 and the cathode power supply 42, ≪ / RTI > electrolysis of water occurs.

The diaphragm 43 passes electrolytically generated ions, and the positive electrode collector 41 and the negative electrode collector 42 are electrically connected to each other through the diaphragm 43. As the diaphragm 43, for example, a solid polymeric material made of a fluorine-based resin material having a sulfonic acid group is used.

In the electrolytic cell 4 having the diaphragm 43 using the solid polymeric material, neutral electrolytic water and electrolytic oxygen are generated. Electrolytic water containing hydrogen gas is obtained in the cathode chamber 40B by electrolysis of water in the electrolytic chamber 40 and electrolytic water of oxygen gas dissolved in the anode chamber 40A is obtained .

The electrolytic water producing apparatus 1 includes a control means 6 for controlling the electrolytic bath 4, a water intake portion 7 provided on the upstream side of the electrolytic bath 4, (8).

The control means 6 has, for example, a CPU (Central Processing Unit) for executing various kinds of arithmetic processing, information processing, and the like, and a program for carrying out the operation of the CPU and a memory for storing various kinds of information.

In the current supply line between the positive electrode current collector 41 and the control means 6, a current detecting means 44 is provided. The current detecting means 44 may be provided in a current supply line between the negative electrode feeder 42 and the control means 6. [ The current detecting means 44 detects the electrolytic current I supplied to the feeders 41 and 42 and outputs a signal corresponding to the detected value to the control means 6.

The control means 6 performs feedback control of the voltage applied between the positive electrode current collector 41 and the negative electrode current collector 42 on the basis of the signal inputted from the current detecting means 44. [ For example, when the electrolytic current is excessively large, the control means 6 decreases the voltage, and when the electrolytic current is excessively small, the control means 6 increases the voltage. Thus, the electrolytic current I supplied to the feeders 41 and 42 can be appropriately controlled.

The water inlet portion 7 has a water supply pipe 71, a flow rate sensor 72, a branch portion 73, a flow rate regulating valve 74, and the like. The water supply pipe 71 is connected to, for example, a water purification cartridge (not shown), and guides the water to be purified by the water purification cartridge to the electrolysis chamber 40. The flow rate sensor 72 is installed in the water supply pipe 71. The flow rate sensor 72 periodically detects the flow rate of water supplied to the electrolytic chamber 40 per unit time (hereinafter sometimes simply referred to as " flow rate ") F and controls the signal corresponding to the flow rate And outputs it to the means (6).

The branching section 73 branches the water supply pipe 71 to both sides of the water supply pipes 71a and 71b. The flow rate adjusting valve 74 connects the water supply pipes 71a and 71b to the anode chamber 40A or the cathode chamber 40B. The flow rate of the water supplied to the anode chamber 40A and the cathode chamber 40B is adjusted by the flow rate regulating valve 74 under the control of the control means 6. [ The flow rate regulating valve 74 regulates the flow rate of water supplied to the anode chamber 40A and the cathode chamber 40B in order to increase the water utilization efficiency. Thereby, a pressure difference may occur between the anode chamber 40A and the cathode chamber 40B.

Since the flow sensor 72 is provided on the upstream side of the branching section 73, the sum of the flow rate of the water supplied to the anode chamber 40A and the flow rate of the water supplied to the cathode chamber 40B, The flow rate F of water supplied to the electrolytic chamber 40 is detected.

The water outlet portion 8 has a flow path switching valve 81, a water tube 82, a drain pipe 83, and the like. The flow path switching valve 81 selectively connects the anode chamber 40A and the cathode chamber 40B to the water discharge pipe 82 or the discharge pipe 83. [ When the electrolytic water producing apparatus 1 is used for producing a dialysis liquid of hemodialysis, the number of electrolytic hydrogen produced in the cathode chamber 40B is diluted through the water tube 82 for the reverse osmosis membrane module for filtration treatment and the dialysis stock solution And the like.

The control means 6 controls the polarity of the DC voltage applied to the positive electrode feeder 41 and the negative electrode feeder 42. For example, the control means 6 accumulates the flow rate F of water supplied to the electrolytic chamber 40 based on the signal inputted from the flow rate sensor 72, and when the predetermined cumulative value is reached, 41 and the negative electrode current source 42 in accordance with the polarity of the DC voltage applied thereto. Thereby, the anode chamber 40A and the cathode chamber 40B are replaced with each other. In switching the polarity of the DC voltage, the control means 6 operates the flow rate adjusting valve 74 and the flow path switching valve 81 synchronously. Accordingly, the cathode chamber 40B and the water tube 82 are always connected, and the electrolytic hydrogen generated in the cathode chamber 40B is discharged from the water tube 82.

2 is a perspective view of the electrolytic bath 4 before assembly. The electrolytic bath 4 includes a first case piece 50 on the anode current collector 41 side, a second case piece 60 on the cathode current collector 42 side, And a second reinforcing member 120 mounted on an outer surface of the second case piece 60. The first reinforcing member 110 is mounted on the first case member 60, The first case piece 50 and the second case piece 60, which are disposed opposite to each other, are fixed to form an electrolytic chamber 40 (see Fig. 1) inside.

The electrolytic bath 4 houses a laminated body 45 in which an anode feeder 41, a diaphragm 43 and a cathode feeder 42 are superimposed in an electrolysis chamber 40.

The anode class bulk body 41 and the cathode class class body 42 are configured such that water can flow in the plate thickness direction, respectively. Mesh-type metal such as expanded metal can be applied to the anode current collector 41 and the anode current collector 42, for example. The mesh type positive electrode feeder 41 and the negative electrode feeder 42 can distribute the water evenly on the surface of the diaphragm 43 while sandwiching the diaphragm 43 therebetween, Lt; RTI ID = 0.0 > electrolysis < / RTI > In this embodiment, as the positive electrode current collector 41 and the negative electrode current collector 42, a platinum plating layer is formed on the surface of an expanded metal made of titanium. Platinum plated layer prevents oxidation of titanium.

A terminal 41a protruding from the electrolytic bath 4 through the first case piece 50 is provided in the anode current collector 41. [ A terminal 41f is attached to the terminal 41a through a sealing member 41b, a bush 41c and nuts 41d and 41e. Likewise, the negative electrode current collector 42 is also provided with a terminal 42a that extends through the second case piece 60 and protrudes outside the electrolytic bath 4. [ The terminal 42a is mounted with the terminal 42f through the sealing member 42b, the bush 42c, and the nuts 42d and 42e, for example. The terminals 41f and 42f are connected to the control means 6 shown in Fig. DC voltage is applied to the positive electrode feeder 41 and the negative electrode feeder 42 through the terminals 41a, 42a and 41f, 42f.

In the electrolytic cell 4 having the diaphragm 43 using the solid polymeric material, neutral electrolytic water is produced. On both sides of the diaphragm 43, a plated layer 43a made of platinum is formed. The plating layer 43a is in contact with the anode feeder 41 and the cathode feeder 42 and is electrically connected.

The diaphragm 43 is sandwiched and supported between the anode feeder 41 and the cathode feeder 42 in the electrolytic chamber 40. Therefore, the shape of the diaphragm 43 is held by the positive electrode feeder 41 and the negative electrode feeder 42. According to the above-described holding structure of the diaphragm 43, most of the stress caused by the pressure difference between the anode chamber 40A and the cathode chamber 40B is absorbed by the positive electrode current collector 41 and the negative electrode current source 42 And the stress applied to the diaphragm 43 is reduced. Accordingly, even when the electrolytic water producing apparatus 1 operates in a state in which a large pressure difference is generated between the anode chamber 40A and the cathode chamber 40B, large stress is not generated in the diaphragm 43. [ Therefore, it is possible to suppress damage to the diaphragm 43 and easily increase the water utilization efficiency.

The diaphragm 43 is sandwiched between the positive electrode current collector 41 and the negative electrode current collector 42 so that the gap between the plating layer 43a of the diaphragm 43 and the positive electrode current collector 41 and the plating layer 43a, The contact resistance between the negative electrode feeder 42 is reduced, and the voltage drop is suppressed. As a result, the electrolysis in the electrolytic chamber 40 is promoted by the sufficient electrolytic current (I), and electrolytic water of high dissolved hydrogen concentration can be generated.

2, a leakage from the mating surface of the first case piece 50 and the second case piece 60 is formed on the outer side of the outer periphery of the positive electrode class feeder 41 and the negative electrode class feeder 42 A sealing member 46 is provided. The outer peripheral portion of the diaphragm 43 is sandwiched between the sealing members 46 and supported.

Each of the case pieces 50 and 60 is formed of a resin such as ABS (acrylonitrile butadiene styrene) or PPS (polyphenylene sulfide). Each case piece 50 and 60 is formed in a rectangular shape elongated in the longitudinal direction (V) along the flow of water in the electrolytic chamber 40. Thus, the electrolytic chamber 40 is formed into a rectangular shape long in the vertical direction (V). The electrolytic cell (40) in the longitudinally elongated shape increases the flow path in the electrolytic bath (4). As a result, the hydrogen gas generated in the cathode chamber 40B can be easily dissolved in the water in the cathode chamber 40B, and the dissolved hydrogen concentration can be increased.

3 (a) is a perspective view of the first case piece 50 seen from the inner surface side facing the electrolysis chamber 40 side. FIG. 3 (b) is a perspective view of the first case piece 50 seen from the outer side, FIG. 4 (a) is a perspective view of the second case piece 60 seen from the inner surface side facing the electrolytic chamber 40 side. FIG. 4 (b) is a perspective view of the second case piece 60).

3 and 4, the first case piece 50 and the second case piece 60 are fixed to the outer edges of the inner surfaces of the first case piece 50 and the second case piece 60 The mating faces 51 and 61 are formed. The inner walls are recessed in the thickness direction of the first case piece 50 and the second case piece 60 from the mating faces 51 and 61 to form electrolytic portions 52 and 62 on the inside of the mating faces 51 and 61, Respectively. The electrolytic section 52 constitutes the anode chamber 40A and the electrolytic section 62 constitutes the cathode chamber 40B.

A plurality of first convex portions 53 are arranged on the inner surface of the first case piece 50. Each of the first convex portions 53 is arranged in the transverse direction H extending in the longitudinal direction V and perpendicular to the longitudinal direction V of the electrolytic portion 52. On the other hand, a plurality of second convex portions 63 are disposed on the inner surface of the second case piece 60. Each of the second convex portions 63 extends in the longitudinal direction (V) and is arranged in the transverse direction (H). The first convex portion 53 and the second convex portion 63 do not impede the movement of water flowing in the electrolytic chamber 40 in the longitudinal direction V. [

Each of the first convex portions 53 contacts the anode current collector 41 in the anode chamber 40A and urges the anode current collector 41 toward the second case piece 60 side. On the other hand, each second convex portion 63 contacts the negative electrode feeder 42 in the negative electrode chamber 40B to urge the negative electrode feeder 42 toward the first case piece 50 side. Therefore, the laminated body 45 is sandwiched between both surfaces of the first convex portion 53 and the second convex portion 63, and is supported. The shape and arrangement of the first convex portion 53 and the second convex portion 63 are arbitrary. For example, as shown in Fig. 4 of Patent Document 1, the first convex portion 53 and the second convex portion 63 are arranged alternately in the transverse direction of the electrolytic chamber with the laminate sandwiched therebetween Or may be arranged so as to face each other with the stacked body sandwiched therebetween as shown in Fig. 8 of Patent Document 1. The first convex portion 53 and the second convex portion 63 may be arranged discretely in the longitudinal direction as shown in Figs. 9 and 10 of the above-mentioned Patent Document 1. [

2, the first reinforcing member 110 and the second reinforcing member 120 are mounted on the outer surfaces of the case pieces 50 and 60, respectively. In the present embodiment, the first reinforcing member 110 and the second reinforcing member 120 are formed by metal-working a metal such as stainless steel. The first reinforcing member 110 and the second reinforcing member 120 are fixed to the first case piece 50 and the second case piece 60 through screws 95 or the like. The first reinforcing member 110 is provided with a female screw 119 corresponding to the screw 95. [ This eliminates the need for a nut or the like in joining the first case piece 50 and the second case piece 60 to reduce the number of parts of the electrolytic bath 4 and improve the productivity of the electrolytic bath 4. [

The first reinforcing member 110 reinforces the first case piece 50. The second reinforcing member 120 reinforces the second case piece 60. Since deformation of the first case piece 50 and the second case piece 60, that is, expansion of the electrolytic bath 4 is suppressed by the first reinforcing member 110 and the second reinforcing member 120, The contact pressure between the diaphragm 43 and each of the power supplies 41 and 42 is sufficiently secured and the contact resistance between the diaphragm 43 and each of the power supplies 41 and 42 is reduced. This makes it easy to obtain a sufficient electrolytic current I without excessively increasing the electrolytic voltage applied to each of the power supplies 41 and 42, thereby making it possible to easily raise the hydrogen gas generating efficiency.

L-shaped seams 91, 92, 93, and 94 are provided in the electrolytic bath 4. [ The seams 91 and 92 are attached to the lower portions of the first case piece 50 and the second case piece 60 and are connected to the flow rate regulating valve 74. The joints 93 and 94 are mounted on the upper portions of the first case piece 50 and the second case piece 60 and are connected to the flow path switching valve 81. By starting water supply to the electrolytic water producing apparatus 1, a flow of water from the lower portion of the anode chamber 40A and the cathode chamber 40B toward the upper portion is generated.

The hydrogen gas generated in the cathode chamber 40B becomes minute bubbles and moves to the upper side of the cathode chamber 40B. In this embodiment, since the direction of flow of hydrogen gas coincides with the direction of flow of water in a large nation, the hydrogen molecules are easily dissolved in water and the concentration of dissolved hydrogen becomes high.

5 (a) is a perspective view of the first reinforcing member 110 seen from the inner surface side toward the first case piece 50, and FIG. 5 (b) is a perspective view of the first reinforcing member 110). 6 (a) is a perspective view of the second reinforcing member 120 viewed from the inner surface side toward the second case piece 60 side, and FIG. 6 (b) is a perspective view of the second reinforcing member 120 seen from the outer surface side Is a perspective view of the member (120).

5 and 6, the first reinforcing member 110 includes a first base portion 111 formed along the outer surface of the first case piece 50, and a second base portion 111 extending from the first base portion 111, And a first rising part 112 formed by the first rising part 112. The rigidity of the first reinforcing member 110 is increased by the first standing portion 112, so that the expansion of the electrolytic bath 4 is further suppressed, thereby further improving the generation efficiency of the hydrogen gas.

Likewise, the second reinforcing member 120 includes a second base portion 121 formed along the outer surface of the second case piece 60 and a second base portion 121 formed by standing from the second base portion 121 122). The rigidity of the second reinforcing member 120 is increased by the second standing portion 122, so that the expansion of the electrolytic bath 4 is further suppressed, thereby further improving the hydrogen gas generating efficiency.

The first rising section 112 includes a first horizontal rising section 113 extending along the transverse direction H perpendicular to the longitudinal direction V and a second transverse rising section 113 extending along the end edge of the first reinforcing member 110 And a first end edge rising portion 114. Likewise, the second rising section 122 includes a second transverse rising section 123 extending along the transverse direction H perpendicular to the longitudinal direction V and a second transverse rising section 123 extending along the end edge of the second reinforcing member 120 And a second end edge rising portion 124 extending therefrom. The first reinforcing member 110 and the second reinforcing member 120 can be easily formed by press-forming a metal plate.

For example, the first transverse standing portion 113 is formed by partially cutting and erecting the first base portion 111. As a result, the through hole 115 is opened in the first base 111. In the present embodiment, a plurality of first transverse rising portions 113 and through holes 115 are arranged in the longitudinal direction (V). A pair of first horizontal rising portions 113 are formed at both ends of the through hole 115 in the longitudinal direction (V). Likewise, the second transverse standing portion 123 is formed by partially cutting and standing the second base portion 121. Thus, the through hole 125 is opened in the second base 121. The arrangements of the second horizontal rising portions 123 and the through holes 125 are the same as those of the first horizontal rising portions 113 and the through holes 115.

The first reinforcing member 110 is preferably formed with the first transverse standing portion 113 and the first trailing edge rising portion 114. The first transverse rising portion 113 and the first transverse rising edge 113, At least one of the electrodes 114 may be formed. The first horizontal rising portion 113 increases the bending rigidity in the transverse direction H of the first reinforcing member 110, that is, in the short direction, and the expansion of the electrolytic bath 4 is further suppressed. The bending rigidity in the vicinity of the end edge of the first reinforcing member 110 is increased by the first end edge rising portion 114 and the expansion of the electrolytic bath 4 is further suppressed. The same holds for the second transverse standing portion 123 and the second end edge rising portion 124.

Instead of the first transverse standing portion 113, a first longitudinal rising portion extending along the longitudinal direction V may be formed on the first reinforcing member 110. In this case, the longitudinal direction V of the first reinforcing member 110, that is, the bending rigidity in the longitudinal direction is increased, and expansion of the electrolytic bath 4 can be suppressed. Similarly, instead of the second transverse standing portion 123, a second vertical rising portion extending along the longitudinal direction V may be formed on the second reinforcing member 120.

As shown in FIG. 3, a first rib 54 is formed in the first case piece 50. The first ribs 54 protrude from the outer wall surface 50a of the first case piece 50 of the electrolytic chamber 40 toward the outside of the electrolytic bath 4. [ The rigidity of the first case piece 50 is increased by the first ribs 54 and the expansion of the electrolytic bath 4 is further suppressed, whereby the efficiency of generating hydrogen gas is further improved.

The first rib 54 has a first transverse rib 55 extending along the transverse direction H and a second transverse rib 55 extending along the end edge of the outer wall surface 50a of the first case piece 50. [ And a rib 56.

The first transverse rib 55 and the first end edge rib 56 are formed in the first case piece 50. The first transverse rib 55 and the first end edge rib 56, May be formed. The bending rigidity in the transverse direction H of the first case piece 50, that is, the short direction, is increased by the first transverse rib 55, and the expansion of the electrolytic bath 4 is further suppressed. The bending rigidity in the vicinity of the end edge of the first case piece 50 is increased by the first end edge rib 56 and the expansion of the electrolytic bath 4 is further suppressed.

In the present embodiment, the plurality of first lateral ribs 55 are arranged in the longitudinal direction (V). A first raised portion 57 protruding from the outer wall surface 50a of the first case piece 50 is formed between adjacent first lateral ribs 55. [ The first raised portion 57 joins the adjacent first lateral ribs 55 and further increases the rigidity of the first case piece 50. The first raised portion 57 may extend to the first end edge rib 56.
