Description

Electrolysis tank and electrolyzed water generator

The present invention relates to an electrolytic cell having electrodes (a cathode plate and an anode plate), and an electrolyzed water generating apparatus including the electrolytic cell.

Generally, an electrolyzed water generating apparatus includes an electrolyzer having electrodes (a cathode plate and an anode plate), and generates alkaline ionized water in the electrolyzer. Alkaline ionized water is said to be effective in improving gastrointestinal symptoms such as relieving stomach upset and stomach discomfort, and assisting gastrointestinal function and improving bowel movements. This reason is considered to be due to the action of hydrogen dissolved in alkaline ionized water. For this reason, it is desired to increase the dissolved hydrogen concentration of alkaline ionized water.

The more dissolved hydrogen is, the stronger it becomes strong alkaline water. However, the pH value of alkaline ionized water increases when it is desired to secure the desired amount of dissolved hydrogen. Therefore, when it is attempted to produce alkaline ionized water at a pH value of 7 to 8 (hereinafter, neutral range) suitable for drinking, a desired dissolved hydrogen amount cannot be ensured.

As a conventional electrolyzed water generating device, an electrolyzed water generating device is known in which a raw water bypass channel branched from the upstream side of the electrolyzer is connected to an ion outflow pipe through which alkaline ionized water generated in the electrolyzer passes ( Patent Document 1). In this conventional electrolyzed water generating apparatus, alkaline ionized water having an increased dissolved hydrogen concentration is diluted with raw water passing through the raw water bypass flow path. As a result, neutral alkaline water having a high dissolved hydrogen concentration and suitable for drinking is produced.

JP 2009-160503 A (JP 2009-160503 A)

However, in the conventional electrolyzed water generating apparatus described above, it is necessary to provide a raw water bypass channel. For this reason, in the conventional electrolyzed water generating apparatus, there existed a problem that manufacturing work (assembly work) will become complicated with becoming a complicated structure. Moreover, in the conventional electrolyzed water generating apparatus, there also existed a problem that a product enlarged by the raw | natural water bypass flow path.

An object of the present invention is to provide an electrolytic cell capable of simplifying the manufacturing work and suppressing an increase in the size of the product, and an electrolyzed water generating apparatus including the electrolytic cell.

In order to solve the above-described problems, the present invention has the following characteristics. First, an electrolytic cell according to the first technical aspect of the present invention has a diaphragm and a cathode plate and an anode plate facing each other with the diaphragm interposed therebetween. An electrolytic cell capable of taking water into acidic water, and has a main channel capable of electrolyzing raw water between a cathode plate and an anode plate, and a sub-channel which does not electrolyze the raw water.

As a result, without providing a raw water bypass channel outside the electrolytic cell as in the prior art, the alkaline ionized water generated by passing through the main channel only in the electrolytic cell is converted to the raw water that has passed through the sub channel. Can be diluted. For this reason, it is not necessary to provide a flow path outside the electrolytic cell, the manufacturing work can be simplified, and an increase in the size of the product can be suppressed.

An opening through which raw water can pass may be formed in at least one of the cathode plate and the anode plate.

Thereby, bubbles generated when the raw water is electrolyzed in the main channel (between the cathode plate and the anode plate) can be discharged from the opening to the sub-channel side (the back side of the cathode plate or the anode plate). Specifically, the raw water flowing through the main flow channel flows slower than the raw water flowing through the sub flow channel due to electrolysis by the cathode plate and the anode plate. For this reason, bubbles generated in the main channel are drawn into the raw water flowing through the sub-channel faster than the main channel through the opening. Therefore, it is difficult for bubbles to exist in the main flow path, and stable electrolysis can be performed by the cathode plate and the anode plate without hindering the electrolysis.

The interval between the cathode plate and the anode plate may be set so as to increase from the upstream side to the downstream side in the raw water flow direction.

Thereby, bubbles generated when the raw water is electrolyzed in the main channel (between the cathode plate and the anode plate) can easily flow from the upstream side to the downstream side in the raw water flow direction. For this reason, the said bubble becomes difficult to adhere to the surface of a cathode plate or an anode plate, and becomes difficult to stay on the surface of a cathode plate or an anode plate. Therefore, it is difficult for bubbles to exist in the main flow path, and stable electrolysis can be performed by the cathode plate and the anode plate without hindering the electrolysis.

A plurality of at least one of a cathode plate and an anode plate are provided, and a relay for controlling a voltage applied to the cathode plate and the anode plate is connected to the cathode plate and the anode plate. May be formed between the cathode plate and the anode plate.

This makes it possible to perform electrolysis with a cathode plate and an anode plate over a wide range in the electrolytic cell without intentionally providing a sub-flow channel. For this reason, it is possible not only to generate neutral alkaline ionized water suitable for drinking, but also to generate alkaline ionized water having a high dissolved hydrogen concentration.

The cathode plate and the anode plate are disposed in a state of being separated from the wall surface of the electrolytic cell, and the sub channel is a cathode side sub channel disposed between the cathode plate and the wall surface of the electrolytic cell, and the anode plate and the electrolytic cell. And an anode-side sub-flow channel disposed between the two wall surfaces.

Thereby, the main flow path and the sub flow path are formed in the thickness direction of the electrolytic cell. For this reason, the alkali ion water produced | generated by passing a main flow path can be diluted with the raw | natural water which passed the subflow path, and the compactization to the transversal direction (width direction) of an electrolytic cell is realizable.

The cathode plate and the anode plate are disposed adjacent to the wall surface of the electrolytic cell and are unevenly distributed in the short direction of the wall surface of the electrolytic cell, and the sub-flow path is an area where the cathode plate and the anode plate are not disposed. It may be formed.

Thereby, in the short direction (width direction) on the wall surface of the electrolytic cell, a main flow path and a sub flow path are formed, and electrolysis by the cathode plate and the anode plate can be performed locally. For this reason, the alkali ion water produced | generated by passing a main flow path can be diluted with the raw | natural water which passed the subflow path, and the compactization to the thickness direction of an electrolytic cell is realizable.

The electrolyzed water generating device according to the second technical aspect of the present invention includes the electrolytic cell according to the first technical aspect of the present invention.

According to the technical aspect of the present invention, it is possible to provide an electrolytic cell capable of simplifying the manufacturing operation and suppressing an increase in the size of the product, and an electrolyzed water generating apparatus including the electrolytic cell.

(1) First Embodiment (1.1) Schematic Configuration of Electrolyzed Water Generating Device First, the schematic configuration of the electrolyzed water generating device 1 according to the first embodiment will be described with reference to FIGS.

As shown in FIG. 1-3, the electrolyzed water generating apparatus 1 can take water from raw water into alkaline ionized water and acidic water by electrolyzing the raw water (applying a voltage to the electrodes). In the first embodiment, as raw water, tap water, well water, and the like are purified by passing through a water purification filter (not shown) (for example, adsorption means such as activated carbon, sand filtration, ion exchange resin) and purified. Shall be used.

The electrolyzed water generating apparatus 1 includes a substantially rectangular electrolytic cell 100 disposed downstream of a water purification filter (not shown). The electrolytic cell 100 includes a plurality of

Specifically, the electrolytic cell 100 includes an electrolytic cell case 110 that can be divided into an upper case 111 and a lower case 112, and a rectangular box-shaped diaphragm case 120 that is accommodated in the electrolytic cell case 110. .

In the electrolytic cell case 110, a cathode chamber 10 containing the

cathode plates

cathode plates

11 and 12 are provided. The anode plate 21 is built in the diaphragm case 120.

Cathode plates

11 and 12 are disposed on both sides of the anode plate 21 (anode chamber 20).

The

cathode plates

11, 12 and the anode plate 21 are disposed at approximately the center in the short direction of the wall surface 113 (the wall surface of the cathode chamber 10 and the wall surface of the anode chamber 20) of the electrolytic cell case 110. The

cathode plates

11 and 12 and the anode plate 21 are respectively provided with electrode terminals T (see FIG. 8A) protruding outward from the lower side of the electrolytic cell case 110. Each electrode terminal T is sealed in a watertight manner by an O-ring, and is connected to an electrode type relay (not shown) for controlling the voltage applied to the

cathode plates

11 and 12 and the anode plate 21.

The electrolytic cell case 110 is provided with a purified water supply pipe 130, an alkaline water outflow pipe 140, and an acidic water outflow pipe 150.

The purified water supply pipe 130 is provided with a supply port 131 for supplying purified water into the electrolytic cell 100 on the upper case 111 side. In the middle of the purified water supply pipe 130, an electrolytic auxiliary agent addition tube 160 filled with an electrolytic auxiliary agent such as a calcium additive that promotes electrolysis is disposed. The purified water supply pipe 130 branches into a cathode supply pipe 130A and an anode supply pipe 130B on the downstream side of the electrolytic auxiliary agent addition cylinder 160 (in the vicinity of the divided part of the upper case 111 and the lower case 112).

The cathode supply tube 130A communicates with the lower side of the lower case 112 (that is, the lower part of the cathode chamber 10). The anode supply pipe 130B communicates with the lower side of the diaphragm case 120 (that is, the lower part of the anode chamber 20).

The alkaline water outflow pipe 140 flows out the alkaline ionized water generated by passing through the cathode chamber 10. The alkaline water outflow pipe 140 communicates with the upper side of the upper case 111. The acidic water outflow pipe 150 flows out acidic water generated by passing through the diaphragm case 120 (the anode chamber 20).

The diaphragm case 120 has an electrolytic diaphragm 120A, and is formed by insert-molding the electrolytic diaphragm 120A and a resin. The diaphragm case 120 constitutes the anode chamber 20. The diaphragm case 120 is formed with an inlet 121A through which purified water flows in and an outlet 121B through which acidic water generated in the diaphragm case 120 flows out. Outflow port 121 </ b> B communicates with acidic water outflow pipe 150.

(1.2) Internal structure of electrolytic cell The internal structure of the electrolytic cell 100 is demonstrated referring FIG. 2, 3 (a), 3 (b).

As shown in FIGS. 2, 3 (a) and 3 (b), each of the

cathode plates

11, 12 and the anode plate 21 has a plate shape and is disposed substantially parallel to the wall surface 113 of the electrolytic cell case 110. The

The cathode plates

11 and 12 are disposed in a state of being separated from the wall surface 113 of the electrolytic cell case 110 and the diaphragm case 120 (anode plate 21).

Specifically, the diaphragm case 120 supports the positioning rib 122 and the

cathode plates

11 and 12 along the longitudinal direction of the electrode (vertical direction in the drawing) so as to correspond to the sides of the

cathode plates

11 and 12. And supporting ribs 123 are formed. The positioning rib 122 positions the

cathode plates

11 and 12 in a state of being separated from the wall surface 113 of the electrolytic cell case 110 and the diaphragm case 120.

In the first embodiment, as shown in FIGS. 3 (a) and 3 (b), the electrolytic cell case 110 is separated from the

cathode plate

11, 12 with respect to the separation distance D 1 from the diaphragm case 120 to the

cathode plate

11, 12. The separation distance D2 to the wall surface 113 is set to about twice (D1: D2 = 1: 2).

The electrolytic cell 100 does not electrolyze the purified water introduced from the purified water supply pipe 130 and the main flow path 30 capable of electrolyzing the purified water introduced from the purified water supply pipe 130 between the

cathode plates

11 and 12 and the anode plate 21. And a secondary flow path 40.

The main flow path 30 is provided between the

cathode plates

11 and 12 and the anode plate 21. On the other hand, the auxiliary flow path 40 is provided between the

cathode plates

11 and 12 and the wall surface 113 of the electrolytic cell case 110. That is, the purified water passing through the sub-flow channel 40 is not electrolyzed by the

cathode plates

11 and 12 and the anode plate 21.

(1.3) Movement of purified water The movement of purified water flowing in the electrolytic cell 100 will be described with reference to FIG.

As shown in FIGS. 1 and 2, the purified water that has passed through the purified water filter (not shown) is introduced into the purified water supply pipe 130 and passes through the electrolytic auxiliary agent addition tube 160. The purified water that has passed through the electrolytic auxiliary agent addition tube 160 branches into the cathode supply tube 130A and the anode supply tube 130B, and is introduced into the cathode chamber 10 and the anode chamber 20 (diaphragm case 120), respectively.

As shown in FIG. 3B, the purified water introduced into the cathode chamber 10 from the cathode supply tube 130A branches into purified water that passes through the main flow path 30 and purified water that passes through the sub flow path 40. The purified water passing through the main flow path 30 is electrolyzed by the

cathode plates

11, 12 and the anode plate 21, and then passes through the sub-flow path 40 where electrolysis by the

cathode plates

11, 12 and the anode plate 21 has not been performed. It is combined with purified water to be discharged and discharged from the alkaline water outflow pipe 140 as alkaline ionized water.

The water introduced into the anode chamber 20 (diaphragm case 120) from the anode supply pipe 130B passes between the anode plate 21 and the diaphragm case 120 and is discharged from the acidic water outflow pipe 150 as acidic water.

(1.4) Actions / Effects As described above, in the electrolyzed water generating apparatus 1 according to the first embodiment, the electrolytic cell 100 includes the main channel 30 capable of electrolyzing the raw water (purified water) and the raw water (purified water). And a sub-flow channel 40 that does not electrolyze. Thereby, the alkali ion water produced | generated by passing the main flow path 30 only in the inside of the electrolytic cell 100, without providing a raw | natural water bypass flow path outside the electrolytic cell 100 like the conventional electrolytic water production | generation apparatus. Can be diluted with purified water that has passed through the sub-channel 40. For this reason, it is not necessary to provide the raw water bypass channel outside the electrolytic cell 100, and the manufacturing operation can be simplified and the increase in size of the product can be suppressed.

Here, as shown in FIG. 4, during the electrolysis by the

cathode plates

11, 12 and the anode plate 21, an electrolytic reaction is locally performed in the main flow path 30 along with the flow of purified water. For this reason, when the pH on the surface of the anode plate 21 is low, a pH concentration gradient is generated in the electrolytic diaphragm 120A, and the neutralization effect that facilitates the alkaline ionized water to be in a neutral region (pH is 7 to 8) is promoted.

Therefore, for example, in the case of water quality that does not contain much carbonic acid component, as shown in FIG. 4A, the pH value tends to increase on the

cathode plate

11, 12 side, and the pH value tends to decrease on the anode plate 21 side. For this reason, the pH concentration gradient in the electrolytic diaphragm 120A is increased, and the neutralization effect is greatly increased, thereby suppressing an excessive increase in the pH value of the alkaline ionized water.

On the other hand, in the case of water quality containing a large amount of carbonic acid components, for example, as shown in FIG. 4B, the pH value does not rise so much on the

cathode plates

11 and 12 side, and the pH value hardly falls on the anode plate 21 side. For this reason, the pH concentration gradient in the electrolytic diaphragm 120A becomes small, and the neutralization effect does not work (is small), thereby reducing the influence of suppressing the increase in the pH value of the alkaline ionized water.

Further, as shown in FIG. 5, when there is no sub-flow channel 40, the inclination becomes steep with respect to the applied current, and the influence of water quality variation (variation in carbonic acid component content) increases. Thereby, pH value of alkaline ionized water exceeds 8.6, and control of purified water becomes difficult.

On the other hand, when the sub-flow channel 40 is provided as in the first embodiment, the inclination with respect to the applied current becomes gentle and the influence due to variations in water quality is reduced. For this reason, it becomes easy to control the purified water, and it becomes possible to obtain weak alkaline alkaline ionized water having a pH of about 8.0 to 8.5.

In the first embodiment, the

cathode plates

11 and 12 and the anode plate 21 are disposed in a state of being separated from the electrolytic cell 100 (the wall surface 113 of the electrolytic cell case 110). Thereby, the main flow path 30 and the sub flow path 40 are formed in the thickness direction of the electrolytic cell 100. For this reason, while being able to dilute the alkali ion water produced | generated by passing the main flow path 30 with the purified water which passed the subflow path 40, it is compact to the short direction (width direction; left-right direction in drawing) of the electrolytic cell 100. Can be realized.

In the first embodiment, the separation distance D2 from the

cathode plates

11 and 12 to the wall surface 113 of the electrolytic cell case 110 is set to about twice the separation distance D1 from the diaphragm case 120 to the

cathode plates

11 and 12. (D1: D2 = 1: 2). Thereby, it becomes easy to dilute the alkali ion water produced | generated by passing the main flow path 30 with the purified water which passed the subflow path 40. FIG.

(1.5) Modified Example An electrolytic cell 100A according to a modified example of the first embodiment will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the same part as the electrolytic cell 100 which concerns on 1st Embodiment, and a different part is mainly demonstrated.

In the electrolytic cell 100 according to the first embodiment, the

cathode plates

11 and 12 are arranged in a state of being separated from the wall surface 113 of the electrolytic cell case 110 and the diaphragm case 120. On the other hand, in the electrolytic cell 100A according to the modified example of the first embodiment, the

cathode plates

11 and 12 are disposed adjacent to the wall surface 113 of the electrolytic cell case 110 as shown in FIG. .

Specifically, the electrode terminal T of the cathode plate 11 is connected to an electrode type first relay Ry1 that controls the voltage applied to the cathode plate 11 and the anode plate 21, and the electrode terminal T of the cathode plate 12 is connected to the electrode terminal T of the cathode plate 12. An electrode-type second relay Ry2 for controlling the voltage applied to the cathode plate 12 and the anode plate 21 is connected. By the switching operation of these relays Ry1 and Ry2, a voltage is applied to only one of the

cathode plates

11 and 12 during electrolysis at low pH, and when electrolysis at high pH is obtained, A voltage may be applied to both.

For example, when obtaining weak alkaline water, only the first relay Ry1 is operated. In this case, the space between the cathode plate 11 and the anode plate 21 becomes the main flow path 30, and the space between the cathode plate 12 and the anode plate 21 becomes the sub flow path 40. Moreover, when obtaining strong alkaline water, both relays Ry1 and Ry2 are operated. In this case, the main flow path 30 is formed between the

cathode plates

11 and 12 and the anode plate 21 without providing the sub flow path 40. That is, the sub flow path 40 is formed between the cathode plate 12 and the anode plate 21 by the switching operation of the relay.

Thus, in the modification of the first embodiment, the main flow path 30 and the sub flow path 40 are formed between the

cathode plates

11 and 12 and the anode plate 21 by the switching operation of the relays Ry1 and Ry2. Thereby, it is possible to perform electrolysis with the

cathode plates

11 and 12 and the anode plate 21 in a wide range in the electrolytic cell 100A without intentionally providing the dedicated sub-flow channel 40. For this reason, while being able to produce | generate the alkaline ionized water of the neutral range suitable for drinking, the alkaline ionized water with high dissolved hydrogen concentration can be produced | generated.

(2) Second Embodiment An electrolytic cell 200 according to a second embodiment will be described with reference to FIGS. 7 (a) and 7 (b). In addition, the same code | symbol is attached | subjected to the same part as the electrolytic cell 100 which concerns on 1st Embodiment, and a different part is mainly demonstrated.

(2.1) Internal configuration of electrolytic cell In the first embodiment,

cathode plates

11 and 12 are disposed on both sides of the anode chamber 20 (anode plate 21). In contrast, in the second embodiment, the cathode plate 11 is disposed on one side of the anode chamber 20 (anode plate 21).

As shown in FIGS. 7A and 7B, the cathode chamber 10 in which the cathode plate 11 is built and the anode chamber 20 in which the anode plate 21 is built are partitioned by a plate-shaped electrolytic diaphragm 124. . The cathode plate 11 and the anode plate 21 are disposed in a state of being separated from the wall surface 113 (the wall surface of the cathode chamber 10 and the wall surface of the anode chamber 20) of the electrolytic cell case 110 and the electrolytic diaphragm 124. In the second embodiment as well, the cathode plate 11 and the anode plate 21 are disposed approximately in the center in the short-side direction of the electrolytic cell 200 (the wall surface 113 of the electrolytic cell case 110).

The main flow path 30 includes a cathode-side main flow path 31 disposed between the

cathode plates

11 and 12 and the electrolytic diaphragm 124, and an anode-side main flow path 32 disposed between the anode plate 21 and the electrolytic diaphragm 124. Consists of.

The sub-channel 40 includes a cathode-side sub-channel 41 disposed between the

cathode plates

11 and 12 and the wall surface 113 of the electrolytic cell case 110 (cathode chamber 10), an anode plate 21 and the electrolytic cell case 110 (anode). It is comprised by the anode side subchannel 42 arrange | positioned between the wall surfaces 113 of the chamber 20).

As described above, in the second embodiment, the cathode plate 11 and the anode plate 21 are disposed in a state of being separated from the electrolytic cell 200 (the wall surface 113 of the electrolytic cell case 110). Thereby, the main flow path 30 and the sub flow path 40 are formed in the thickness direction (depth direction in the drawing) of the electrolytic cell 200. For this reason, while being able to dilute the alkali ion water produced | generated by passing the main flow path 30 with the purified water which passed the subflow path 40, compactization to the transversal direction (width direction) of the electrolytic cell 200 is realizable.

(2.2) Modified Example An electrolytic cell according to a modified example of the second embodiment will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same part as the electrolytic cell 100 which concerns on 1st Embodiment, and a different part is mainly demonstrated.

(2.2.1) Modification 1
An electrolytic cell 200A according to Modification 1 of the second embodiment will be described with reference to FIG.

In the electrolytic cell 200 according to the second embodiment, the cathode plate 11 and the anode plate 21 have a plate shape in which no opening or the like is formed. On the other hand, in the electrolytic cell 200A according to the first modification of the second embodiment, the cathode plate 11 has an opening 11A penetrating the cathode plate 11, as shown in FIGS. Are formed, and the anode plate 21 is formed with a plurality of openings 21 </ b> A penetrating the anode plate 21. Air bubbles generated by electrolysis of the cathode plate 11 and the anode plate 21 can pass through the opening 11A and the opening 21A. The openings 11A and the openings 21A are arranged in a lattice shape when the cathode plate 11 and the anode plate 21 are viewed from the front.

Thus, in the electrolytic cell 200A according to Modification 1 of the second embodiment, the opening 11A or the opening 21A is formed in at least one of the cathode plate 11 and the anode plate 21. Thereby, bubbles generated when the purified water is electrolyzed in the main flow path 30 (between the cathode plate 11 and the anode plate 21) from the opening to the sub flow path 40 side (the back side of the cathode plate 11 or the anode plate 21). ) Can be discharged. Specifically, the purified water flowing through the main flow path 30 flows slower than the purified water flowing through the sub flow path 40 due to electrolysis by the cathode plate 11 and the anode plate 21. For this reason, bubbles generated in the main flow path 30 are drawn into the purified water flowing through the sub flow path 40 that is earlier than the main flow path 30 via the opening 11A or the opening 21A. Accordingly, it is difficult for bubbles to exist in the main flow path 30, and stable electrolysis can be performed by the cathode plate 11 and the anode plate 21 without the bubbles hindering electrolysis.

In the electrolytic cell 200A according to the first modification of the second embodiment, the openings 11A and the openings 21A are arranged in a lattice shape when the cathode plate 11 and the anode plate 21 are viewed from the front. As a result, bubbles generated in the main channel 30 are easily drawn into the purified water flowing through the sub-channel 40 faster than the main channel 30 via the opening 11A or the opening 21A, and are less likely to exist in the main channel 30. .

Here, the openings 11A and the openings 21A have been described as being arranged in a grid pattern in the front view of the cathode plate 11 and the anode plate 21, but the present invention is not limited to this, and the arrangement method is not limited thereto. Can be set arbitrarily.

(2.2.2) Modification 2
An electrolytic cell 200B according to Modification 2 of the second embodiment will be described with reference to FIG.

In the electrolytic cell 200 according to the second embodiment, the cathode plate 11 and the anode plate 21 have a plate shape in which no opening or the like is formed. On the other hand, in the electrolytic cell 200B according to the modified example 2 of the second embodiment, a plurality of openings 11A are formed in the cathode plate 11 as in the electrolytic cell 200A according to the modified example 1 of the second embodiment. A plurality of openings 21 </ b> A are formed in the plate 21.

Further, as shown in FIG. 9, the cathode plate 11 and the anode plate 21 are disposed in an inclined state with respect to the wall surface 113 of the electrolytic cell case 110. Specifically, the distance D between the cathode plate 11 and the anode plate 21 is set so as to gradually increase from the upstream side to the downstream side in the purified water flow direction (from the bottom to the top in the drawing).

Thus, in the electrolytic cell 200B according to Modification 2 of the second embodiment, the distance between the cathode plate 11 and the anode plate 21 is set wider from the upstream side to the downstream side in the flow direction of the purified water. Thereby, bubbles generated when purified water is electrolyzed in the main flow path 30 (between the cathode plate 11 and the anode plate 21) can easily flow from the upstream side toward the downstream side in the flowing direction of the purified water. For this reason, the generated bubbles are less likely to adhere to the surfaces of the cathode plate 11 and the anode plate 21 and are less likely to stay on the surfaces of the cathode plate 11 and the anode plate 21. Accordingly, it is difficult for bubbles to exist in the main flow path 30, and stable electrolysis can be performed by the cathode plate 11 and the anode plate 21 without the bubbles hindering electrolysis.

(3) Third Embodiment An electrolytic cell 300 according to a third embodiment will be described with reference to FIGS. 10 (a) and 10 (b). In addition, the same code | symbol is attached | subjected to the electrolytic cell 100 (100A) which concerns on 1st Embodiment mentioned above, and the electrolytic cell 200 (200A, 200B) which concerns on 2nd Embodiment, and a different part is mainly demonstrated. To do.

(3.1) Internal configuration of electrolytic cell In the electrolytic cell according to the first and second embodiments, the cathode plate 11 (12) and the anode plate 21 are provided on the wall surface 113 of the electrolytic cell case 110 (the wall surface of the cathode chamber 10). And the wall surface of the anode chamber 20). On the other hand, in the electrolytic cell 300 according to the third embodiment, as shown in FIGS. 10A and 10B, the cathode plate 11 and the anode plate 21 are separated from the electrolytic cell 300 (the wall surface of the electrolytic cell case 110). 113) are arranged unevenly in the lateral direction.

In this case, the main channel 30 is disposed between the cathode plate 11 and the anode plate 21, and the sub-channel 40 is formed in a region where the cathode plate 11 and the anode plate 21 are not disposed. .

As described above, in the electrolytic cell 300 according to the third embodiment, the cathode plate 11 and the anode plate 21 are adjacent to the electrolytic cell 300 (the wall surface 113 of the electrolytic cell case 110) and are unevenly distributed in the short direction of the wall surface 113. It is arrange | positioned in the state made. Thereby, the main flow path 30 and the sub flow path 40 are formed in the short direction (width direction) in the wall surface 113, and the electrolysis by the cathode plate 11 and the anode plate 21 can be performed locally. For this reason, it is possible to dilute the alkaline ionized water generated by passing through the main flow path 30 with the purified water that has passed through the sub flow path 40, and to achieve downsizing of the electrolytic cell 300 in the thickness direction.

Specifically, although the electrolyzed water production | generation apparatus 1 demonstrated as what has a water purification filter, it is not limited to this, For example, the apparatus (For example, the bottle water server which stores drinking water) which does not have a water purification filter Or the like.

Moreover, although the electrolytic cell case 110 was demonstrated as what can be divided | segmented into the upper case 111 and the lower case 112, it is not limited to this, Even if comprised by one case and a cover body Good.

Moreover, although the electrolytic cell 100 according to the first embodiment has been described as having the plurality of
