As a result, it is possible to prevent bubbles from remaining in the vicinity of the interface of the groove, thereby further increasing the dissolved concentration of the electrolytic product in the liquid.

Further, a plurality of the grooves are formed so as to be aligned in the liquid flow direction, and the width of the projection in the liquid flow direction at least at the contact portion with the electrolytic section is between the adjacent grooves in the electrolytic section. is smaller than the width in the direction of liquid flow.

Further, the protrusion is formed to have a polygonal contour shape with an R portion formed at the vertex when viewed from the stacking direction.

In this way, by forming the R portion at the apex portion of the contour shape of the protrusion, the flow of the liquid in the vicinity of the protrusion can be made smoother, thereby suppressing the occurrence of stagnation of air bubbles. It is possible to further improve the dissolved concentration of the electrolytic product in the liquid.

The extension wall 62b is formed so as to overlap the guide projection (introduction guide portion) 353 when viewed from the longitudinal direction (flow direction: front-rear direction X).

In the present embodiment, by providing such an extended wall 62b, it is possible to suppress the occurrence of turbulent flow in the vicinity of the guide projection (introduction guide portion) 353. As shown in FIG.

A plurality of projections 64 arranged along the longitudinal direction (liquid passing direction: front-rear direction X) is formed at the center of the lower surface 62a of the fitting projection 62 in the width direction Y. As shown in FIG.

Then, when the electrolytic part 80 is accommodated in the second concave portion (electrolytic part accommodating space) 342 via the elastic body 90 and the electrode case lid 60 is attached to the electrode case 20 , the electrode case lid 60 is provided with a The electrolytic portion 80 is pressed downward by the projecting portion 64 .

As described above, in the present embodiment, by pressing the electrolytic section 80 downward, a constant pressure is applied to the entire electrolytic section 80 by the elastic body 90, and the members constituting the electrolytic section 80 are brought into close contact with each other. It is designed to enhance sexuality.

Further, when the electrode case lid 60 is attached to the electrode case 20 , the upper surface 80 a of the electrolytic section 80 (the surface on one side in the stacking direction Z) is made substantially flush with the intermediate surface 351 . By doing so, formation of a step in the flow path 11 is suppressed. In addition, the cross-sectional area of the flow path (the electrolysis-section-side flow path 14) formed in the upper portion of the electrolytic section 80 is made substantially the same as the cross-sectional area of the other flow paths.

By making the cross-sectional areas of the flow paths 11 substantially the same as described above, it is possible to prevent the flow of water (liquid) flowing through the flow paths 11 from being disturbed. As a result, it is possible to suppress the generation of a stagnation portion in the flow path 11, and it is possible to suppress the generated ozone (electrolysis product) from growing into bubbles, and the flow rate of the gas from the outflow port 11b can be suppressed. It becomes possible to further improve the concentration of ozone (electrolyzed product) in the discharged ozone water (electrolyte liquid).

Next, a specific configuration of the electrolytic section 80 will be described.

As shown in FIGS. 16 and 17 , the electrolyzer 80 has a substantially rectangular shape with the liquid flow direction X being the longitudinal direction when viewed from the stacking direction Z. As shown in FIG. The electrolytic section 80 includes a laminate 81 configured by laminating an anode 84, a conductive film 86, and a cathode 85 in this order. Thus, in the present embodiment, laminate 81 is laminated such that conductive film 86 is interposed between adjacent electrodes (anode 84 and cathode 85). In the present embodiment, a power feeder 83 made of titanium, for example, is layered under the anode 84 , and electricity is supplied to the anode 84 via this power feeder 83 .

Furthermore, in the present embodiment, a groove 82 having an opening 82a that opens to the flow path 11 is formed in the laminate 81, and the groove 82 is formed at least at an interface 88 between the conductive film 86 and the cathode 85. It is configured such that a portion can come into contact with water (liquid). At least part of the interface 87 between the conductive film 86 and the anode 84 is also configured to be in contact with water (liquid).

Specifically, the cathode 85 is formed with a cathode side hole 85c, and the conductive film 86 is formed with a conductive film side hole 86c. When the cathode 85 and the conductive film 86 are laminated, the cathode side hole 85c and the conductive film side hole 86c are communicated with each other.

Therefore, the inner side surface 86d of the conductive film 86 and the inner side surface 85d of the cathode 85 form the side surface 82c of the groove 82, and the upper surface (surface) 84a of the anode 84 forms the bottom surface 82b of the groove 82 (see FIG. 20). By forming such a groove portion 82, at least a portion of an interface 88 between the conductive film 86 and the cathode 85 (interface between the conductive film and the electrode) is exposed to the groove portion 82. Water can now freely contact the interface 87 . Moreover, at least a part of the interface 87 between the conductive film 86 and the anode 84 (the interface between the conductive film and the electrode) is also exposed in the groove 82, so that water can freely contact the interface 87 exposed in the groove 82. become.

In the present embodiment, the groove portion 82 is formed so as to have a shape in which both ends in the width direction Y of the groove portion elongated in the width direction Y are bent upstream. That is, the cathode-side hole 85c formed in the cathode 84 and penetrating in the stacking direction Z is formed in a V shape with the bending point portion disposed on the downstream side.

A conductive film-side hole 86c formed in the conductive film 86 and penetrating in the stacking direction Z is also formed in a V shape with a bending point portion disposed on the downstream side. A V-shaped groove 82 is formed by connecting the membrane side hole 86c.

Moreover, in the present embodiment, a plurality of grooves 82 are formed so as to line up along the longitudinal direction X, but at least one groove 82 may be formed.

The interface 88 between the conductive film 86 and the cathode 85 in this embodiment is the boundary line between the side surface of the cathode 85 and the side surface of the conductive film 86 . An interface 87 between the conductive film 86 and the anode 84 is a line of intersection between the surface of the anode 84 and the side surface of the conductive film 86 .

The conductive film 86 and the cathode 85 may have the same size or may have different sizes, but at least the mutual holes (the cathode side hole 85c and the conductive film side hole 86c) need to communicate with each other. Also, a sufficient electrical contact area must be secured. Therefore, in consideration of these, it is preferable that the conductive film 86 and the cathode 85 have substantially the same projected dimension (they have substantially the same size when viewed from the stacking direction Z).

In addition, the anode 84 may have the same size as the conductive film 86 and the cathode 85, or may have a different size. is preferred.

In this embodiment, the anode 84, the cathode 85 and the conductive film 86 are made to have substantially the same projected dimensions.

By doing so, when the laminated body 81 is formed, the sides of the anode 84, the cathode 85, and the conductive film 86 are arranged to be substantially flush with each other.

That is, when the laminate 81 is formed, at least the side surfaces 84b, 85b, and 86b of the anode 84, the cathode 85, and the conductive film 86 extending in the longitudinal direction are made substantially flush.

Further, in the present embodiment, the power feeder 83 and the elastic body 90 are also made to have approximately the same projected dimensions as the anode 84, the cathode 85 and the conductive film 86. FIG.

A shaft attachment piece 85e is formed at one end of the cathode 85, and a cathode-side power supply shaft 85f is attached to the shaft attachment piece 85e by welding or the like. By attaching the cathode-side power supply shaft 85f to the shaft attachment piece 85e in this manner, the cathode-side power supply portion 80c is formed.

The cathode 85 is electrically connected to the power source section 100 via a lead wire 101a on the cathode 101 side connected to the cathode side power supply shaft 85f.

In this embodiment, the cathode-side power supply shaft 85f is also attached to the shaft attachment piece 85e so as to extend in the stacking direction Z. As shown in FIG. The cathode 85 is inserted into the second concave portion (electrolytic unit accommodating space) 342 with the cathode-side power supply shaft 85f extending toward the opposite side (lower side) of the flow path 11. .

That is, the grooves 82 are formed so that the height H1 of the flow path 11 in the stacking direction Z>the depth D1 of the grooves 82, or the opening width L1 of the grooves 82 in the liquid flow direction X>the depth D1 of the grooves 82. ing.

In this embodiment, the height H1 of the flow path 11 in the stacking direction Z is set to about 2 mm as described above.

Further, since the depth D1 of the groove portion 82 is the sum of the thickness of the conductive film 86 and the thickness of the cathode 85, it is about 0.6 mm to about 0.7 mm in this embodiment.

Furthermore, in the present embodiment, the protrusion 64 is in contact only with the upper surface (the surface on one side in the stacking direction Z) 80a of the electrolytic section 80 . That is, when viewed from the stacking direction Z, at least the contact portion 64a of the protrusion 64 that contacts the electrolytic portion 80 is prevented from overlapping the groove portion 82 .

Specifically, as shown in FIG. 21, at least the width L2 in the liquid passing direction of the contact portion 64a of the protrusion 64 with the electrolytic portion 80 is equal to the width L3 in the liquid passing direction between the grooves 82 adjacent to each other in the electrolytic portion 80. , so that the protrusion 64 contacts only the upper surface 80a of the electrolytic section 80 (the surface on one side in the stacking direction Z).

The ozone water generator (electrolyte liquid generator) 1 having such a configuration can be assembled, for example, by the following method.

First, the elastic body 90 is inserted into the recess 34 from the side of the opening 332 a of the electrode case 20 , and the elastic body 90 is arranged in the second recess (electrolytic section housing space) 342 .

Next, while the power feeder 83 is inserted into the recess 34 from the opening 332a side of the electrode case 20 with the tip of the anode power feed shaft 83b facing downward, the anode power feed shaft 83b is moved to one side. The body portion of the power supply body 83 is laminated on the elastic body 90 by inserting it into the power supply part insertion hole 313a.

Next, the anode 84 is inserted into the recess 34 from the opening 332 a side of the electrode case 20 to stack the anode 84 on the power feeder 83 .

Next, the conductive film 86 is inserted into the recess 34 from the opening 332 a side of the electrode case 20 to stack the conductive film 86 on the anode 84 .

Next, while the cathode 85 is inserted into the recess 34 from the opening 332a side of the electrode case 20 with the tip of the cathode-side power supply shaft 85f facing downward, the cathode-side power supply shaft 85f is inserted into the other power supply. The body portion of the cathode 85 is laminated on the conductive film 86 by inserting it through the insertion hole 313a.

At this time, each member constituting the elastic body 90 and the electrolysis section 80 is inserted into the second recess (electrolysis section accommodation space) 342 while being guided by the guide projection (introduction guide section) 353 .

However, simply stacking the members constituting the elastic body 90 and the electrolysis section 80 in the recess 34 leaves the elastic body 90 in a substantially free state (a state in which it is hardly elastically deformed).

Therefore, at least the cathode 85 of the electrolytic section 80 is in a state of floating above the intermediate surface 351 (see FIG. 18). However, relative movement in the longitudinal direction X of the cathode 85 floating above the intermediate surface 351 is suppressed by a guide projection (introduction guide portion) 353 . In the present embodiment, each member constituting the elastic body 90 and the electrolytic portion 80 is positioned in the width direction Y by the width direction side inner surface 321a.

After that, by moving the electrode case lid 60 relative to the electrode case 20 in the stacking direction Z, the welding protrusion 62 is inserted into the groove 333a while fitting the fitting projection 62 into the opening 332a.

Then, the electrode case cover 60 and the electrode case 20 are welded to each other by vibration welding, heat welding, or the like while fitting the fitting projection 62 into the opening 332a and inserting the welding projection 62 into the groove 333a. .

Thus, the electrode case lid 60 seals the recess 34 of the electrode case 20 .

At this time, the upper surface (surface on one side in the stacking direction Z) 80a of the electrolytic section 80 is pressed downward by the extended wall 62b and the protrusion 64, so that the electrolytic section 80 elastically deforms the elastic body 90. The whole is inserted into the second concave portion (electrolytic portion housing space) 342 (see FIG. 19).

Next, an O-ring 314 is inserted from the tip of the shaft (the anode-side power-supply shaft 83b and the cathode-side power-supply shaft 85f) of the power supply portion 80a exposed to the outside of the tip electrode case 20, and formed in the pressure plate accommodation recess 313. It is arranged in the O-ring insertion groove 313b.

Then, the tip of the shaft (the anode side power supply shaft 83b and the cathode side power supply shaft 85f) of the power supply portion 80a is inserted into the shaft insertion hole 316a formed in the pressure plate 316, and the pressure plate 316 is inserted into the pressure plate accommodation recess 313. accommodate the

Then, the pressing plate 316 is fixed to the electrode case 20 by inserting the screws 315 into the screw insertion holes 316b formed in the pressing plate 316 and the screw holes 313c formed in the pressing plate accommodating recess 313 and screwing them.

Thus, the ozone water generator (electrolyte liquid generator) 1 is assembled. As described above, the ozone water generator (electrolytic liquid generator) 1 according to the present embodiment can be assembled only by relatively moving each member in the stacking direction Z with respect to the electrode case 20 .

In the above embodiment, the anode-side power supply shaft 83b and the cathode-side power supply shaft 85f are welded to the shaft mounting pieces 83a and 85e.

In FIG. 22, the anode side power supply shaft 83b is provided separately from the power supply body 83 (anode 84), and the cathode side power supply shaft 85f is provided separately from the cathode 85. In FIG.

When the ozonized water generator (electrolyte liquid generator) 1 is assembled, the respective shafts are brought into contact with the feeder 83 and the cathode 85 .

Note that FIG. 22 illustrates that both the anode-side power supply shaft 83b and the cathode-side power supply shaft 85f are separated. It is also possible to use the body.

Further, as shown in FIG. 23, at least one of the members constituting the electrolytic section 80 may be curved in the stacking direction Z. In addition, as shown in FIG.

FIG. 23 illustrates a configuration in which the feeder 83 and the cathode 85, which are members arranged at both ends in the stacking direction Z among the members constituting the electrolytic section 80, are curved in the stacking direction Z. FIG. Although not shown in FIG. 23, the cathode 85 is formed with a cathode side hole communicating with the conductive film side hole 86c.

When the ozone water generating device (electrolyte liquid generating device) 1 is assembled using such curved members, the curved members are made to have a substantially flat plate shape.

By doing so, when the ozone water generator (electrolytic liquid generator) 1 is assembled, pressing pressure is generated against the conductive film 86 .

That is, in FIG. 23, the power feeder 83 and the cathode 85 are curved in the stacking direction Z, so that the power feeder 83 and the cathode 85 have the function of the elastic body 90 shown in the above embodiment. .

As described above, the power feeder 83 and the cathode 85 are curved in the stacking direction Z, and the power feeder 83 and the cathode 85 generate pressing pressure against the conductive film 86, as shown in FIG. As shown, even when the ozone water generator (electrolyte liquid generator) 1 is assembled without using the elastic body 90, the adhesion between the members constituting the electrolytic section 80 can be further enhanced. Become.

FIG. 23 illustrates an example in which the ozone water generator (electrolyte liquid generator) 1 is assembled without using the elastic body 90. It is also possible to arrange the elastic body 90 below the power supply body 83 while forming a curved shape.

Also, the curved shape of the members constituting the electrolysis unit 80 can be any shape as long as it is a shape that generates pressing pressure against the conductive film 86 when the ozone water generator (electrolyte liquid generator) 1 is assembled. shape. For example, in FIG. 23, it is curved in a direction (lamination direction Z) orthogonal to the longitudinal direction X (liquid passing direction) and curved so as to be convex toward the conductive film 86 side. It may be curved so as to be convex on the side opposite to the 86 side. Alternatively, it may have a shape in which a plurality of portions are curved, such as a waveform.

Further, it is possible to bend only one of the power feeder 83 and the cathode 85, and it is also possible to bend other members constituting the electrolytic section 80. FIG. That is, when the ozonized water generator (electrolyte liquid generator) 1 is assembled, any member among the members constituting the electrolysis unit 80 can be used as long as it is configured to generate a pressing pressure against the conductive film 86 . The shape can be curved.

Next, the operation and action of the ozone water generator (electrolyte liquid generator) 1 having such a configuration will be described.

First, in order to supply water (liquid) to the ozone water generator (electrolyte liquid generator) 1, water (liquid) is supplied from the inlet 11a to the channel 11. As shown in FIG.

A part of the water supplied to the flow path 11 flows into the groove portion 82 and contacts the interfaces 87 and 88 of the groove portion 82 .

When the power supply unit 100 is turned on and a voltage is applied between the anode 84 and the cathode 85 of the electrolysis unit 80 by the power supply unit 100 in such a state (a state in which the electrolysis unit 80 is immersed in the supplied water), A potential difference is generated between the anode 84 and the cathode 85 via the conductive film 86 . By generating a potential difference between the anode 84 and the cathode 85 in this way, the anode 84, the conductive film 86 and the cathode 85 are energized, and the water in the groove 82 is subjected to electrolytic treatment. Ozone (electrolysis product) is generated in the vicinity of the interfaces 87 and 88 between the electrode and the anode 84 .

The voltage applied at this time ranges from several volts to several tens of volts, and the higher the voltage (the higher the current value), the greater the amount of ozone (electrolyzed product) generated.

Ozone (electrolyzed product) generated in the vicinity of the interfaces 87 and 88 between the conductive film 86 and the anode 84 is transported along the flow of water (liquid) to the downstream side of the channel 11 while the water ( liquid). In this manner, dissolved ozone water (ozone water: electrolytic liquid) is generated by dissolving ozone (electrolyzed product) in water (liquid).

Such an ozonated water generator (electrolyte liquid generator) 1 can be applied to an electric device that uses the electrolyte liquid generated by the electrolyte liquid generator, a liquid reformer equipped with the electrolyte liquid generator, and the like. .

In addition, as electric equipment and liquid reforming equipment, water treatment equipment such as water purifiers, washing machines, dishwashers, hot water washing toilet seats, refrigerators, hot water supply equipment, sterilization equipment, medical equipment, air conditioning equipment, or kitchen equipment, etc.

As described above, the ozone water generator (electrolyte liquid generator) 1 according to the present embodiment includes the laminate 81 which is laminated such that the conductive film 86 is interposed between the electrodes 84 and 85 adjacent to each other. and includes an electrolyzer 80 that electrolyzes water (liquid) and a housing 10 in which the electrolyzer 80 is arranged.

Further, the housing 10 is formed with a channel 11 in which the liquid passing direction X intersects with the stacking direction Z of the stack 81 .

The flow path 11 includes an inlet 11a, which is communicated with a water path (upstream external flow path) 71a of the upstream pipe 71 and into which the liquid supplied to the electrolysis unit 80 flows, and a water path of the downstream pipe 72 (downstream side). and an outflow port 11b through which the ozone water (electrolyte liquid) generated in the electrolysis unit 80 flows out, which is communicated with the external flow path 72a.

Further, the electrolytic section 80 is formed with a groove section 82 that opens to the flow path 11 and exposes at least part of the interfaces 87 and 88 between the conductive film 86 and the electrodes 84 and 85 .

Furthermore, the housing 10 is formed with a recess 34 having an opening 332a through which the electrolytic part 80 can be inserted, and covers the electrode case 20 in which the electrolytic part 80 is accommodated in the recess 34 and the opening 332a of the electrode case 20. and an electrode case lid 60 .

The electrolytic section 80 is accommodated in the recess 34 with the stacking direction Z of the laminate 81 approximately aligned with the opening direction of the opening 332a.

As a result, the mounting direction of the electrode case lid 60 to the electrode case 20 can be substantially aligned with the stacking direction Z of the laminate 81 . As a result, by moving each member constituting the electrolytic part 80 and the electrode case lid 60 relative to the electrode case 20 in the stacking direction Z, the ozone water generator (electrolyte liquid generator) 1 can be assembled. become. Thus, according to the present embodiment, it is possible to obtain the ozone water generator (electrolyte liquid generator) 1 that can be assembled more easily.

Further, in the present embodiment, flow path 11 is formed between electrolytic section 80 and electrode case lid 60 .

In this way, the flow path 11 can be formed by covering the opening 332a of the electrode case 20 with the electrode case cover 60 while the electrolysis unit 80 is housed in the recess 34 . Therefore, the ozone water generator (electrolyte liquid generator) 1 having the flow path 11 can be assembled more easily.

By the way, in the electrolytic liquid generating apparatus disclosed in Patent Document 1, an electrolytic electrode device is formed by simply laminating an anode, a conductive film, and a cathode. Therefore, when stacking the anode, the conductive film, and the cathode, the positional relationship of each member may shift in the direction intersecting the stacking direction Z (on the XY plane).

When the anode, the conductive film and the cathode are laminated, if the positional relationship of each member deviates in the direction intersecting the lamination direction Z (on the XY plane), the contact area of the anode, the conductive film and the cathode may increase or decrease, and the concentration of ozone (electrolyzed product) in the ozone water (electrolyte liquid) may become unstable.

In particular, if each member is displaced in the flow channel width direction Y, the exposed amount of the interface in the groove fluctuates greatly. It may become stable.

Therefore, in the present embodiment, the electrodes 84 and 85 and the conductive film 86 are laminated so that at least the side surfaces 84b, 85b and 86b extending in the longitudinal direction are substantially coplanar.

In this way, the stack 81 can be positioned in the flow path width direction Y simply by making the side surfaces 84b, 85b, and 86b extending in the longitudinal direction flush with each other. Positioning of the channel width direction Y of 81 can be performed more easily.

In addition, by making it possible to suppress positional displacement in the flow channel width direction Y, which greatly affects the ability to generate ozone (electrolysis products), the concentration of ozone (electrolysis products) in the ozonized water (electrolyte liquid) can be made more stable.

Further, the electrode case 20 is provided with an introduction guide portion 353 that extends in the stacking direction Z of the laminate 81 and guides the insertion of the electrolytic portion 80 into the recess 34 .

By providing the introduction guide portion 353 in this way, when assembling the ozone water generator (electrolyte liquid generator) 1, the positions of the members constituting the laminate 81 can be prevented from being displaced during assembly. is suppressed, and the ozone water generator (electrolyte liquid generator) 1 can be assembled more easily.

Further, in the electrolytic liquid generating apparatus disclosed in Patent Document 1, as described above, the electrolytic electrode device is formed by simply stacking the anode, the conductive film, and the cathode. Gaps may be created between parts. If gaps are formed between the components, there is a risk that the energization on the lamination surface of the laminate will become non-uniform. If the energization on the laminate surface of the laminate becomes uneven in this way, the efficiency of generating ozone (electrolyzed product) may decrease, and the service life of the electrodes and the conductive film may be shortened. There is a risk of

Therefore, in the present embodiment, the elastic body 90 is arranged in the housing 10 so as to be in contact with one side in the lamination direction Z of the laminate 81 in the electrolytic section 80 .

By providing the elastic body 90 in this manner, one side of the electrolytic section 80 in the stacking direction Z can be pressed by the elastic body 90 , and the dimensional variation of the electrolytic section 80 in the stacking direction Z can be suppressed by the elastic body 90 . can be absorbed by As a result, the positioning of the electrolytic section 80 in the stacking direction Z can be performed more easily.

Further, by providing the elastic body 90, it becomes possible to apply a constant pressure to the entire electrolytic section 80, so that the adhesion of each member can be further enhanced. By increasing the adhesion of each member in this manner, the efficiency of generating ozone (electrolysis product) can be further improved, and the life of the electrodes and the conductive film can be extended. Become.

Further, if the elastic body 90 enhances the adhesion of each member, it becomes possible to simplify the structure and more easily assemble the electrolytic section 80 in which the adhesion of each member is enhanced.

Further, in the present embodiment, an elastic body 90 is arranged between the electrolytic section 80 and the electrode case 20 .

In this way, when assembling the ozone water generator (electrolyte liquid generator) 1, the elastic body 90 can be arranged inside the electrode case 20 (inside the recess 34), so that the ozone water generator ( Electrolyte liquid generator) 1 can now be assembled.

In addition, a welded portion 17 is formed at the peripheral edge portion 333 of the opening 332a of the housing 10, where the electrode case 20 and the electrode case lid 60 are welded together.

By doing so, the electrode case lid 60 can be attached to the electrode case 20 more easily, and the ozone water generator (electrolyte liquid generator) 1 can be assembled more easily.

Also, in this embodiment, the electrodes comprise an anode 84 and a cathode 85 . Furthermore, the electrolysis unit 80 is electrically connected to the anode 84 and has an anode-side power supply shaft 83b that applies voltage to the anode 84, and a cathode-side power supply shaft 83b that is electrically connected to the cathode 85 and applies voltage to the cathode 85. and a power supply shaft 85f.

The anode-side power supply shaft 83b and the cathode-side power supply shaft 85f are extended in the stacking direction Z. As shown in FIG.

By doing so, it is possible to uniquely determine the size and position of each member constituting the electrolytic section 80, and it is possible to suppress the positional deviation of each member during lamination. As a result, the assembly of the electrolysis unit 80 and the alignment of each member can be performed more easily, and ozone (electrolysis product) can be generated more stably.

Further, in the present embodiment, the anode-side power supply shaft 83b and the cathode-side power supply shaft 85f are extended toward the opposite side of the flow path 11. As shown in FIG.

By doing so, it is possible to prevent the anode-side power supply shaft 83b and the cathode-side power supply shaft 85f from being arranged in the channel 11, so that water (liquid) flowing in the channel 11 is prevented from stagnation. be able to

Further, in the present embodiment, the anode-side power supply shaft 83b, which is either one of the anode-side power supply shaft 83b and the cathode-side power supply shaft 85f, is provided on the inlet 11a side of the electrolysis unit 80. As shown in FIG. A cathode-side power supply shaft 85f, which is the other, is provided on the outflow port 11b side of the electrolysis unit 80. As shown in FIG.

In this way, the distance between the anode-side power supply shaft 83b and the cathode-side power supply shaft 85f can be maximized while preventing the ozone water generator (electrolyte liquid generator) 1 from becoming large. As a result, it is possible to suppress short-circuiting between the anode 84 and the cathode 85 while suppressing an increase in the size of the ozone water generator (electrolyte liquid generator) 1 .

In addition, the electrolytic section 80 has a substantially rectangular shape with the liquid passing direction X being the longitudinal direction when viewed from the stacking direction Z. It is provided at the corner 80b.

By doing so, it is possible to eliminate the directionality of the inlet side and the outlet side of the electrode case 20, so that the ozone water generator (electrolytic liquid generator) 1 can be assembled more efficiently. Become.

At this time, at least one of the anode-side power supply shaft 83b and the cathode-side power supply shaft 85f can be provided separately from the electrodes 84,85.

This eliminates the need to weld the anode-side power supply shaft 83b and the cathode-side power supply shaft 85f. As a result, each member constituting the electrolysis unit 80 can be processed more easily, and the cost can be reduced.

Further, at least one member (power feeder 83 and cathode 85) among the members constituting electrolytic section 80 may be curved in stacking direction Z. FIG.

This makes it possible to generate a stable pressing pressure against the electrodes 84 and 85 when the ozone water generator (electrolyte liquid generator) 1 is assembled. As a result, the current-carrying area of the electrolysis unit 80 can be more stably secured, and the ability to generate ozone (electrolyzed product) can be more stabilized. In addition, since it is not necessary to tighten the electrolytic part 80 arranged in the electrode case 20 with a screw or the like, it is possible to suppress the occurrence of variations in assembly and further stabilize the ability to generate ozone (electrolyzed product). be able to Furthermore, since the number of parts can be reduced, the cost can be reduced.

In addition, the above Patent Document 1 discloses an electrolytic liquid generating device provided with a baffle structure for turbulent tap water passing through the electrolytic electrode device, and by providing such a baffle structure, It is designed to electrolyze tap water more efficiently.

However, simply generating turbulent flow cannot obtain enough hydraulic power to forcibly strip the microbubbles of the electrolysis product from the interface of the electrode, and the generated electrolysis product does not peel off from the interface of the electrode. It may grow into a large bubble in a short period of time.

As described above, when the bubbles of electrolytic products grow large, even if they are separated from the interface of the electrode, they may float in the liquid without being dissolved in the liquid, and the dissolved concentration of the electrolytic products in the liquid decreases. There is a risk of doing so.

Therefore, in the present embodiment, the groove portion 82 is formed so that the depth D1 is smaller than at least one of the opening width L1 of the groove portion 82 in the liquid flow direction X and the height H1 of the flow path 11 in the stacking direction Z. formed.

Thus, if the height H1 of the flow path 11 in the stacking direction Z>the depth D1 of the groove 82, or the opening width L1 of the groove 82 in the flow direction X>the depth D1 of the groove 82, then ozone (electrolytic Since the water flow speeds up at the location (near the interface 87) where the product) is generated, it is possible to strip off the generated ozone (electrolysis product) in the state of ultrafine bubbles. As a result, ozone (electrolytic product) is prevented from floating in the liquid without being dissolved in the liquid, and the dissolved concentration of ozone (electrolytic product) in water (in the liquid) can be further improved. become.

In addition, since it is possible to suppress the water (liquid) flowing in the flow path 11 from remaining in the groove 82, ozone (electrolyzed product) in water (in the liquid) It becomes possible to further improve the dissolution concentration of

In addition, Patent Document 1 above also discloses an electrolytic liquid generating device in which an anode, a conductive film, and a cathode are laminated, water passage holes are provided in the conductive film and the cathode, and a water passage (flow path) is one path. By adopting such a configuration, it is possible to reduce the size and cost of the electrolytic liquid generating device.

However, in Patent Document 1, the height of the flow path is not defined at all. Therefore, depending on the structure of the flow path, the flow velocity of the liquid flowing through the flow path may become extremely slow. As described above, in the structure of Patent Document 1, there is a possibility that the dissolved concentration of the electrolytic product in the liquid may decrease.

Therefore, in the present embodiment, the flow path 11 is formed so that the height in the stacking direction Z is a height H1 that is smaller than the flow path width W1.

Thus, if the flow path 11 is formed so that the height in the stacking direction Z has a height H1 that is smaller than the flow path width W1, the surface flow velocity in the vicinity of the interfaces 87 and 88 can be increased. become. Therefore, the generated ozone (electrolysis product) can be dissolved in water (liquid) more quickly, and the dissolved concentration of ozone (electrolysis product) in water (liquid) can be further improved. will be able to

Further, in the structure of Patent Document 1, as described above, the anode, the conductive film, and the cathode are simply laminated, so the contact between the anode and the conductive film and the connection between the conductive film and the cathode Contact may become uneven.

Thus, when the contact between the anode and the conductive film and the contact between the conductive film and the cathode become uneven, the dissolved concentration of the electrolysis products becomes unstable, and the generation efficiency of the electrolysis products decreases. There is a risk of

Therefore, in the present embodiment, the protruding portion 64 is brought into contact with the surface 80a of the electrolytic portion 80 on the flow path 11 side.

By bringing such projections 64 into contact with the flow path 11 side surface 80a of the electrolytic section 80, the electrolytic section 80 can be pressed by the projections 64. , 85 can be made more uniform. As a result, the current density of the current flowing through the electrolysis section 80 can be made more uniform, and the efficiency of generating ozone (electrolyzed product) can be further improved. In addition, the dissolved concentration of ozone (electrolysis product) in water (in liquid) can be stabilized.

Further, in the present embodiment, the protrusion 64 is formed in the central portion of the channel 11 in the channel width direction Y. As shown in FIG.

By pressing the central portion of the electrolytic portion 80 with the protrusion 64 in this manner, the conductive film 86 and the electrodes 84 and 85 can be brought into more uniform contact. As a result, the current density of the current flowing through the electrolysis section 80 can be made more uniform, and the efficiency of generating ozone (electrolyzed product) can be further improved. In addition, the dissolved concentration of ozone (electrolysis product) in water (in liquid) can be stabilized.

Further, in the present embodiment, a plurality of protrusions 64 are formed so as to line up in the liquid passing direction X. As shown in FIG.

In this manner, if the protrusion 64 presses the electrolytic portion 80 along the liquid feeding direction X, the conductive film 86 and the electrodes 84 and 85 can be brought into more uniform contact. As a result, the current density of the current flowing through the electrolysis section 80 can be made more uniform, and the efficiency of generating ozone (electrolyzed product) can be further improved. In addition, the dissolved concentration of ozone (electrolyzed product) in water (liquid) can be more stabilized.

Further, in the present embodiment, the protrusions 64 are formed so that at least the contact portions 64a with the electrolytic section 80 do not overlap the grooves 82 when viewed in the stacking direction Z. As shown in FIG.

By doing so, it is possible to prevent the projections 64 from being arranged on the grooves 82 , so that the flow of water (liquid) in the grooves 82 is prevented from being obstructed by the projections 64 . become. As a result, the generation of air bubbles in the vicinity of the interfaces 87 and 88 of the groove 82 is suppressed, and the dissolved concentration of ozone (electrolyzed product) in water (liquid) can be further improved. become.

Further, in the present embodiment, a plurality of grooves 82 are formed so as to line up in the liquid passing direction X. As shown in FIG. At least the width L2 in the liquid passage direction of the contact portion 64a of the projection 64 with the electrolytic portion 80 is made smaller than the width L3 in the liquid passage direction between adjacent groove portions 82 in the electrolytic portion 80. As shown in FIG.

In this way, even if the positions of the projections 64 are slightly displaced during assembly of the ozone water generator (electrolyte liquid generator) 1 , the projections 64 can be prevented from being arranged on the grooves 82 . Therefore, it is possible to more reliably suppress the generation of air bubbles in the vicinity of the interfaces 87 and 88 of the groove 82, and further improve the concentration of dissolved ozone (electrolyzed product) in water (in the liquid). be able to

Further, in the present embodiment, the protrusions 64 are formed so that, when viewed from the stacking direction Z, the outline shape 64b has a polygonal shape with rounded portions 64d formed at the vertex portions 64c.

By forming the rounded portion 64d at the apex portion 64c of the outline shape 64b of the protrusion 64 in this manner, the liquid can flow more smoothly in the vicinity of the protrusion 64, so that air bubbles do not accumulate. This makes it possible to more reliably suppress the dissolution of ozone (electrolyzed product) in water (liquid), thereby further increasing the dissolved concentration of ozone (electrolyzed product).

Chlorous acid may be generated and used for sterilization, water treatment, and the like. It is also possible to use a device that generates oxygen water, hydrogen water, chlorine-containing water, hydrogen peroxide water, and the like.

Also, the anode 84 can be made of, for example, conductive silicon, conductive diamond, titanium, platinum, lead oxide, tantalum oxide, etc., and is an electrode having conductivity and durability capable of generating electrolyzed water. Any material may be used. Further, when the anode 84 is a diamond electrode, its manufacturing method is not limited to the manufacturing method by film formation.
