Application of Article 30, Paragraph 2 of the Patent Act On March 17, 2016, Techno Excel Co., Ltd. sold the mixer and electrolyzed water generator invented by the inventor of the present application to Morinaga Dairy Co., Ltd.

The present invention comprises a mixer for producing electrolyzed water by mixing an electrolyzed product produced by electrolysis of an aqueous electrolyte solution with source water, and electrolyzed water provided with such a mixer and an electrolytic cell. It is about a generator.

For example, in the following patent documents, dilute hydrochloric acid supplied from a dilute hydrochloric acid tank to an electrolytic cell is electrolyzed to generate hypochlorite water, and the generated hypochlorite water is mixed with water in a storage tank. As a result, the invention of an electrolyzer for producing hypochlorite water (hereinafter, also simply referred to as “electrolyzer”) that produces a hypochlorite water having a desired concentration is disclosed. In this case, in this electrolytic cell, the electrolytic cell is connected to the intermediate portion of the circulation pipeline connected to the storage tank. Further, in this electrolyzer, the hypochlorite water generated in the electrolytic cell is mixed with the water in the circulation pipe through the mixing pipe, so that the connection portion with the mixing pipe in the circulation pipe is "". A configuration is adopted in which the hypochlorite water and water are mixed by functioning as a "mixer".

Japanese Unexamined Patent Publication No. 2012-115479 (Page 3-5, Fig. 1-3)

However, the electrolytic apparatus disclosed in the above patent document has the following problems. That is, in the above-mentioned electrolyzer, the hypochlorite water generated in the electrolytic cell is mixed with the water in the circulation pipe to mix the hypochlorite water and water to obtain a desired concentration of hypochlorite. A configuration that produces acid water is adopted. In this case, in this electrolyzer, the inside of the electrolytic cell (electrolysis treatment space) and the inside of the circulation pipe are always in communication with each other via the mixing pipe. Therefore, in this electrolyzer, the pressure in the circulation pipe applied by the circulation pump to pump water from the storage tank directly acts in the mixing pipe. Therefore, in this electrolyzer, a part of the water pumped into the circulation pipe by the circulation pump may enter the inside of the electrolytic cell (electrolysis treatment space) through the mixing pipe.

In such a case, the amount of hypochlorous acid generated in the electrolytic cell supplied to the circulation pipe due to the infiltration of water into the mixing pipe (the liquid flows back in the mixing pipe). Decreases, making it difficult to produce the desired concentration of hypochlorous acid. Further, as a result of diluting the dilute hydrochloric acid supplied from the dilute hydrochloric acid tank into the electrolytic cell by the water that has entered the electrolytic cell through the mixing pipeline, the electrolysis efficiency in the electrolytic cell is lowered, and the inside of the circulation conduit is reduced. In, the amount of hypochlorite water to be mixed with water per unit time decreases, or the concentration of hypochlorite water produced decreases. Therefore, the electrolytic apparatus disclosed in the above patent document has a problem that it takes a long time to generate a hypochlorite water having a desired concentration and the power consumption is increased.

Therefore, according to the mixer according to claim 1 and the electrolyzed water generator according to claim 3, due to the presence of the partition portion provided with the communication hole, the source water is introduced from the first introduction port from the upstream space. However, since the pressure in the space on the downstream side where the electrolytic product from the electrolytic cell is introduced can be sufficiently lowered, the situation where the source water invades the electrolytic cell through the second introduction port is suitably avoided. be able to. As a result, according to this mixer and the electrolytic cell generator, it is possible to avoid the situation where the electrolytic cell aqueous solution in the electrolytic cell is diluted by the source water, so that the electrolysis efficiency of the electrolytic cell aqueous solution in the electrolytic cell is sufficiently improved.

Further, by avoiding the infiltration of the source water from the mixer into the electrolytic cell, the electrolytic product produced in the electrolytic cell can be efficiently supplied from the electrolytic cell to the mixer, so that the electrolysis at a desired concentration can be performed. Water can be efficiently generated in a short time.

Hereinafter, embodiments of the mixer and the electrolyzed water generator according to the present invention will be described with reference to the accompanying drawings.

The electrolyzed water generating device 1 shown in FIG. 1 corresponds to the "electrolyzed water generating device", and as an example, "electrolyzed generation" is performed by electrolyzing the "electrolyzed water solution (electrolyzed water)" supplied from the electrolyzed water tank 2. It is configured so that "electrolyzed water" can be generated and stored in the electrolyzed water tank 3 by generating "objects" and mixing the generated "electrolyzed products" with "source water". In the electrolytic water generation device 1 of this example, as an example, the "electrolytic product" generated by electrolyzing water as the "electrolyte aqueous solution (water to be electrolyzed)", saline solution, dilute hydrochloric acid, etc. is used as the "source water". It is configured so that hypochlorite water as "electrolyzed water" can be produced by mixing with tap water as "electrolyzed water".

The electrolyzed water generating device 1 includes an electrolytic cell 10, a metering pump 11, a check valve 12, a power supply unit 13, a solenoid valve 14, a flow rate sensor 15, and a controller 16. The electrolytic cell 10 is made by mixing an electrolytic cell body 10a (a "bipolar electrolytic cell" which is an example of an "electrolyzing tank") and an "electrolysis product" generated in the electrolytic cell body 10a with tap water. A mixing portion 10b (an example of a "mixer") that produces chlorinated water is integrally formed.

It is configured with.

In the electrolysis of dilute hydrochloric acid by this type of device, "gas components" such as chlorine, hydrogen and oxygen and water (water used to dilute hydrogen chloride in the production of dilute hydrochloric acid: remained without electrolysis. A "mixed fluid" with a "liquid component" such as (extremely low concentration dilute hydrochloric acid containing hydrogen chloride) is produced as an "electrolytic product". Further, a part of chlorine constituting the above-mentioned "gas component" reacts with water as the above-mentioned "liquid component", whereby hypochlorite water is generated in the electrolytic cell.

However, for the "electrolytic product" generated by electrolysis, that is, the "mixed fluid" discharged from the electrolytic cell, the concentration of dilute hydrochloric acid used as the "electrolyte aqueous solution (electrolyzed solution)" and the electrolytic treatment conditions (unit). The concentration of hypochlorite water as a "liquid component" (generated by electrolysis) depends on the amount of dilute hydrochloric acid supplied to the electrolytic cell per hour and the voltage value of the DC voltage applied to the electrodes in the electrolytic cell. How much of chlorine reacts with water in the electrolytic cell) and the ratio of chlorine etc. to the "gas component" are different. Therefore, in this example, in order to facilitate the understanding of the configuration of the electrolyzed water generator 1, chlorine, hydrogen and oxygen contained in the "electrolyzed product" composed of the above "mixed fluid" are not distinguished. The hypochlorite water contained in the "electrolyzed product", which is referred to as "gas component", is referred to as "liquid component" and will be described below.

In the container body 21, the processing tank side container body 21a, the mixing portion side container body 21b, and the partition portion 21c (see FIG. 4) are integrally formed of a resin material (as an example, vinyl chloride). The container body 21a on the processing tank side is a box-shaped container body having one side opened, and together with the lid body 22, constitutes a "treatment tank" of the electrolytic cell body 10a, and includes an electrode plate 23 and an electrode holder. An electrolytic processing space S1 (see FIGS. 4 and 5) capable of accommodating 25 and the like is formed. In the processing tank side container body 21a, as will be described later, a plurality of supply holes 31 for supplying the "electrolysis product" generated in the electrolytic treatment space S1 to the mixing unit 10b (inside the mixing unit side container body 21b). (See FIGS. 4, 6 and 7) and an insertion hole 32 (see FIGS. 4 and 5) through which the connection conductor 24 connected to the electrode plate 23 housed in the electrolytic treatment space S1 can be inserted are formed. Has been done.

The container body 21b on the mixing portion side is an example of the “container body” and is formed in a cylindrical shape as shown in FIGS. See). The container body 21b on the mixing portion side has a flange 35a for connecting the introduction port 35 on the one end side (an example of the "first introduction port") to the water supply, and the discharge port 36 on the other end side ("outlet port"). An example) is formed with a flange 36a for connecting the electrolyzed water tank 3 to the electrolytic water tank 3. In the electrolytic cell 10 (mixing section 10b) of this example, the opening on the mixing section side container body 21b side in each supply hole 31 communicated with the processing tank side container body 21a to the mixing section side container body 21b is formed. Corresponds to the "second introduction port".

The partition portion 21c is an example of the “partition portion”, and as shown in FIGS. A container body 21b on the mixing portion side so as to partition S4a (an example of an "upstream space") and a downstream space S4b (an example of an "downstream space") on the discharge port 36 side for discharging hypochlorite water. It is integrally formed. As shown in FIGS. 6 and 7, the partition portion 21c is provided with a communication hole 37 (an example of a “communication hole”) for communicating the upstream space S4a and the downstream space S4b with each other, whereby the upstream side is provided. The passage of tap water from the space S4a to the downstream space S4b is allowed. In this case, in the electrolytic cell 10 (mixing section 10b) of this example, as shown in FIG. 6, four communication holes 37 are opened in the partition section 21c.

Further, in the electrolytic cell 10 (mixing unit 10b) of this example, as shown in FIG. 7, each of the "electrolyzed products" generated in the electrolytic cell body 10a is introduced into the mixing processing space S4 of the mixing unit 10b. The supply holes 31 are opened in the downstream space S4b, respectively. As a result, in the electrolytic cell 10 (mixing unit 10b) of this example, the "electrolysis product" supplied from the electrolytic cell body 10a is introduced into the downstream space S4b in the mixing processing space S4.

The lid 22 is a member that closes the opening of the container 21a on the processing tank side in the container 21 to form the electrolytic treatment space S1 together with the container 21a on the processing tank side, and is shown in FIGS. 2 to 5. As shown, an introduction hole 33 for introducing dilute hydrochloric acid supplied from the electrolyzed water tank 3 into the electrolysis treatment space S1 and a connection conductor 24 connected to the electrode plate 23 housed in the electrolysis treatment space S1. An insertable hole 34 is formed. In this case, in the electrolytic cell 10 (electrolytic cell body 10a) of this example, the processing tank side container body is provided with the lid 22 attached to the processing tank side container body 21a accommodating the electrode plate 23 and the connecting conductor 24. The contact portion between the 21a and the lid 22 is ultrasonically welded to integrate the two.

As shown in FIG. 3, the electrode plate 23 is formed in a rectangular shape in a plan view by a metal material having high corrosion resistance to hydrochloric acid or the like (for example, a titanium plate coated with a noble metal oxide such as platinum or ruthenium). Note that FIG. 3 illustrates only three of the seven electrode plates 23 included in the electrolytic cell 10 in order to facilitate understanding of the shapes and the like of the components of the electrolytic cell 10. In this case, in the electrolytic cell 10 (electrolytic cell main body 10a) of this example, as shown in FIGS. 4 and 5, each electrode plate 23 is housed in an upright state in the electrolytic cell processing space S1.

The connecting conductor 24 is a conductor for connecting the two electrode plates 23 arranged on both end sides of the seven electrode plates 23 housed in the electrolytic processing space S1 to the power supply unit 13. As shown in FIG. 3, as an example, it is formed in a columnar shape by a metal material such as titanium, and is welded to the electrode plate 23 in a state of being erected in the center of the electrode plate 23.

As shown in FIGS. It is configured to be receivable. Specifically, in the electrode holder 25, the frame-shaped holding portion 41 and the plurality of partition portions 42 are integrally formed of a resin material (for example, vinyl chloride). In this case, in the electrode holder 25 of this example, as shown in FIG. 3, the frame-shaped holding portion 41 is formed in a square frame shape in accordance with the shapes of the processing tank side container body 21a and the electrode plate 23 in the container body 21. ing. In the figure, only two of the six electrode holders 25 included in the electrolytic cell 10 are shown in order to facilitate understanding of the shapes and the like of the components of the electrolytic cell 10. ..

Further, in the electrode holder 25 of this example, as shown in FIGS. A configuration is adopted in which the frame-shaped holding portion 41 is in contact with the outer edge portion to hold both the electrode plates 23 and 23. In this case, the frame-shaped holding portion 41 is provided with a rectangular opening 41a slightly smaller than the outer shape of the electrode plate 23, and each partition arranged at equal intervals in the inner space S2 of the opening 41a. The inner space S2 is partitioned by the portion 42 into a plurality of unit spaces S3 adjacent to each other in the width direction of the electrode plate 23 to be held.

Further, as shown in FIG. 4, in the electrode holder 25 of this example, the dilute hydrochloric acid introduced into the electrolytic treatment space S1 from the introduction hole 33 is introduced from the vicinity of the lid 22 to the lid 22 in the container 21a on the treatment tank side. The frame consists of a plurality of recesses 45 that allow flow to face the opposite surface side, and a plurality of recesses 46 that allow dilute hydrochloric acid flowing through each recess 45 to flow into the inner space S2 (each unit space S3). It is formed on each of the lower beam portions of the shape holding portion 41. Further, in the electrode holder 25 of this example, a plurality of recesses 47 in which the "electrolyzed product" generated in each unit space S3 can enter, and the "electrolyzed product" that has entered each of the recesses 47 are supplied. A plurality of holes 48 for guiding to the holes 31 are formed in the upper beam portion of the frame-shaped holding portion 41, respectively.

In the electrode holder 25 of this example in which the inner space S2 of the frame-shaped holding portion 41 is divided into 10 unit spaces S3 by nine partitioning portions 42, the recesses 45 to 47 and the holes 48 are respectively. Ten of each are provided corresponding to the unit space S3. Further, as shown in FIG. 7, the container body 21 is provided with the above-mentioned 10 supply holes 31 corresponding to the positions of the holes 48.

In this case, in the electrolytic cell 10 (electrolytic cell body 10a) of this example, as shown in FIGS. 4 and 5, two of the seven electrode plates 23 on both ends (connecting conductors 24 are connected to each other). One of the electrode plates 23) is held in the electrolytic processing space S1 so as to be sandwiched between one of the six electrode holders 25 and the lid 22, and the two electrode plates 23 are held. The other of the six electrode holders 25 is sandwiched between the other one of the six electrode holders 25 and the forming surface of the supply hole 31 in the processing tank side container body 21a so as to be sandwiched in the electrolytic cell processing space S1. It is being held.

Further, in the electrolytic cell 10 (electrolytic cell main body 10a) of this example, the frame-shaped holding portions 41 of the electrode holders 25 are housed in the electrolytic processing space S1 in a state of being in contact with each other, and two adjacent electrodes are held. Five of the seven electrode plates 23, excluding the above two, are held in the electrolytic processing space S1 so that the outer edge portion is sandwiched between the frame-shaped holding portions 41, 41 in the tools 25, 25. ing.

On the other hand, the metering pump 11 is composed of a tube pump as an example, and supplies dilute hydrochloric acid from the electrolyzed water tank 2 to the electrolytic cell 10 (electrolyzed tank main body 10a) according to the control of the controller 16. As shown in FIG. 1, the check valve 12 is arranged in a connection pipe connecting the metering pump 11 and the electrolytic cell 10 (introduction hole 33 of the electrolytic cell body 10a), and the metering pump 11 (water to be electrolyzed). The passage of dilute hydrochloric acid from the tank 2) toward the electrolytic cell 10 is permitted, and the passage of dilute hydrochloric acid from the electrolytic cell 10 toward the metering pump 11 is restricted. The power supply unit 13 applies a DC voltage for electrolytic processing between the electrode plates 23 and 23 via both connecting conductors 24 under the control of the controller 16.

The electromagnetic valve 14 is arranged between the water supply and the electrolytic cell 10 (introduction port 35 of the mixing section 10b), and allows / regulates the supply of tap water from the water supply to the electrolytic cell 10 according to the control of the controller 16. The flow sensor 15 is disposed between the electromagnetic valve 14 (water supply) and the electrolytic cell 10, and detects the flow rate of tap water that passes through the electromagnetic valve 14 and is supplied to the electrolytic cell 10 (mixing section 10b). And outputs the sensor signal.

The controller 16 comprehensively controls the electrolyzed water generator 1. Specifically, the controller 16 controls the metering pump 11 to supply dilute hydrochloric acid from the electrolyzed water tank 2 to the electrolytic cell 10 (electrolysis tank main body 10a), and controls the power supply unit 13 to electrolyze the electrolytic cell 10 (electrolysis). A DC voltage is applied to each electrode plate 23) of the tank body 10a, and the electromagnetic valve 14 is controlled according to the sensor signal from the flow sensor 15 to supply a specified amount of tap water to the electrolytic cell 10 (mixing unit 10b). Let me.

In the electrolyzed water generation device 1, when an operation unit (not shown) is operated to instruct the start of generation of hypochlorite water, the controller 16 controls the metering pump 11 to electrolyze the electrolyzed water tank 2 from the electrolyzed water tank 2. Dilute hydrochloric acid is supplied to 10 (electrolyzed water tank main body 10a), and the power supply unit 13 is controlled to start applying a DC voltage between the electrode plates 23 and 23. At this time, the dilute hydrochloric acid supplied by the metering pump 11 is introduced into the electrolytic processing space S1 of the electrolytic cell 10 (electrolytic cell main body 10a) from the introduction hole 33, and each recess 45 provided in each electrode holder 25. Is flowed over the entire bottom of the electrolytic cell treatment space S1.

Further, when the dilute hydrochloric acid is further supplied by the metering pump 11, the dilute hydrochloric acid in each recess 45 flows into each unit space S3 through each recess 46, and each electrode facing the electrode holder 25 is interposed therebetween. The plate 23 is in contact with dilute hydrochloric acid. As a result, the dilute hydrochloric acid in contact with the electrode plate 23 is electrolyzed to generate an "electrolytic product" composed of a "mixed fluid" of a "gas component" and a "liquid component".

On the other hand, the "gas component" generated in each unit space S3 is generated in the electrolytic treatment space S1 generated by the increase in pressure in the unit space S3 due to the generation of gas and the sequential supply of dilute hydrochloric acid by the metering pump 11. Due to the increase in pressure in each unit space S3), it enters each hole 48 through each recess 47 in the electrode holder 25, and enters the mixing processing space S4 (downstream side) in the mixing portion 10b through each supply hole 31. It is supplied to the space S4b).

Further, the controller 16 is in parallel with the above-mentioned control regarding the supply of dilute hydrochloric acid to the electrolytic cell 10 (electrolytic cell main body 10a) by the metering pump 11 and the application of the DC voltage between the electrode plates 23 and 23 by the power supply unit 13. Then, while monitoring the sensor signal from the flow sensor 15, the electromagnetic valve 14 is controlled to start supplying tap water to the electrolytic cell 10 (mixing unit 10b). As a result, a specified amount of tap water is supplied from the introduction port 35 into the mixing processing space S4 (upstream side space S4a) of the mixing unit 10b.

In this case, in the electrolytic cell 10 (mixing section 10b) of this example, the upstream space S4a on the introduction port 35 side where tap water is introduced and the downstream side where the "electrolysis product" from the electrolytic cell body 10a is introduced. The space S4b is partitioned by the partition portion 21c, and the upstream space S4a and the downstream space S4b are communicated with each other through a small communication hole 37 provided in the partition portion 21c. Therefore, when the electromagnetic valve 14 is opened by the controller 16 and tap water is supplied from the water supply to the mixing portion 10b (introduction port 35), the water pressure of the tap water introduced into the upstream space S4a from the introduction port 35 causes. The pressure inside the upstream space S4a becomes high to some extent, and tap water flows from the upstream space S4a into the downstream space S4b through the communication holes 37.

At this time, the water pressure of the tap water flowing into the downstream space S4b becomes sufficiently lower than that of the upstream space S4a due to the pressure loss generated when passing through each communication hole 37. Therefore, in the mixing section 10b of this example, tap water flowing into the downstream space S4b does not invade the inside of the electrolytic cell main body 10a (inside the electrolysis treatment space S1) from each supply hole 31. The "electrolyzed product" supplied through the supply hole 31 and the tap water flowing into the downstream space S4b via the communication hole 37 are suitably mixed in the downstream space S4b to form hypochlorite. Water is produced.

In this case, an "electrolyzed product (mixed fluid)" containing extremely low-concentration hypochlorite water as a "liquid component" and a sufficient amount of chlorine as a "gas component" passes through each supply hole 31. When the water is supplied from the main body 10a of the electrolytic tank, chlorine as a "gas component" is mixed with tap water in the downstream space S4b to generate hypochlorite water having a desired concentration, and the "liquid component" is produced. When the "electrolyzed product (mixed fluid)" containing a high concentration of hypochlorite water is supplied from the electrolytic tank main body 10a through each supply hole 31, this hypochlorite water is on the downstream side. By mixing with tap water and diluting in the space S4b, hypochlorite water having a desired concentration is produced.

Further, in the mixing portion 10b of this example, a plurality of (four in this example) communication holes 37 are provided in the partition portion 21c that partitions the upstream side space S4a and the downstream side space S4b. In this case, even when a configuration is adopted in which one "communication hole" having an opening area equal to the total opening area of each communication hole 37 is provided in the partition portion 21c instead of the four communication holes 37, the tap water is the same. The magnitude of the pressure loss that occurs when passing through the "communication holes" is about the same as the magnitude of the pressure loss that occurs when tap water passes through the above four communication holes 37. Therefore, even in a configuration in which one "communication hole" is provided in the partition portion 21c instead of the four communication holes 37, the downstream space S4b is lower than the upstream space S4a in the same manner as the mixing portion 10b of this example. Can be pressure.

However, in the configuration where only one "communication hole" is provided in the partition portion 21c, only one tap water flows into the downstream space S4b from the upstream space S4a, so that the downstream space S4b is already provided. The inflowing tap water (or hypochlorite water in which "electrolytic product" and tap water are mixed) and the tap water newly flowing into the downstream space S4b from the "communication hole" are on the downstream side. There is a possibility that the water is discharged from the discharge port 36 without being suitably stirred in the space S4b.

On the other hand, in the mixing portion 10b of this example in which a plurality of communication holes 37 are provided in the partition portion 21c, the tap water in the upstream space S4a is tap water (or hypochlorite water) in the downstream space S4b. ), The tap water (or hypochlorite water) in the downstream space S4b is suitably agitated by a plurality of jets of tap water from each communication hole 37. To. As a result, the "electrolyzed product" and tap water (or hypochlorite water) are suitably mixed. After that, the hypochlorite water generated in the downstream space S4b is discharged from the discharge port 36 and stored in the electrolyzed water tank 3.

As described above, in the mixing unit 10b, the introduction port 35 for introducing "source water (tap water in this example)", the supply hole 31 for introducing "electrolyzed product", and "electrolyzed water (in this example)". , Hypochlorite water) ”is provided in the mixing section side container body 21b provided with the discharge port 36, and the inside of the mixing section side container body 21b (mixing processing space S4) is the upstream side space S4a on the introduction port 35 side and It is provided with a partition portion 21c provided with a communication hole 37 for partitioning the downstream space S4b on the discharge port 36 side and for communicating the two spaces S4a and S4b with each other, and the supply hole 31 is supplied from the electrolytic cell body 10a. The "electrolyzed product" is open so that it can be introduced into the downstream space S4b. Further, the electrolyzed water generating device 1 includes the above-mentioned mixing unit 10 and the electrolytic cell main body 10a, and is configured to be able to generate "electrolyzed water".

Therefore, according to the mixing unit 10b and the electrolyzed water generator 1, the presence of the partition portion 21c provided with the communication hole 37 causes the electrolytic cell body 10a to be more than the upstream space S4a into which tap water is introduced from the introduction port 35. Since the pressure in the downstream space S4b into which the "electrolysis product" from the above is introduced can be sufficiently lowered, the situation where tap water invades the electrolytic cell body 10a through the supply hole 31 is suitably avoided. can do. As a result, according to the mixing unit 10b and the electrolytic cell generation device 1, it is possible to avoid the situation where the dilute hydrochloric acid in the electrolytic cell body 10a is diluted with tap water, so that the electrolysis efficiency of the dilute hydrochloric acid in the electrolytic cell body 10a is sufficient. The amount of electric power required for electrolysis can be sufficiently reduced. Further, by avoiding the infiltration of tap water from the mixing section 10b into the electrolytic cell body 10a, the "electrolyzed product" generated in the electrolytic cell body 10a is efficiently supplied from the electrolytic cell body 10a to the mixing section 10b. Therefore, it is possible to efficiently generate hypochlorite water having a desired concentration in a short time.

Further, according to the mixing unit 10b and the electrolyzed water generator 1, tap water from each communication hole 37 is formed by forming a plurality of communication holes 37 (four in this example) in the partition portion 21c of the mixing unit 10b. The tap water and the "electrolyzed product" can be suitably stirred in the downstream space S4b by the jet flow of the above, and both can be suitably mixed.

Further, according to the electrolytic cell generator 1, the "electrolyzer tank" and the "mixer" are formed by integrally forming the mixing section side container body 21b in the mixing section 10b and the treatment tank side container body 21a in the electrolytic cell body 10a. Compared to the configuration in which "" is formed as a separate body and integrated by screwing, etc., the space required for installing the "electrolyzer tank" and "mixer" can be sufficiently reduced, and the "electrolyzer tank" can be sufficiently reduced. ] And the sealing for sealing the joint portion of the “mixer” are not required, so that the manufacturing cost of the electrolytic cell generator 1 can be sufficiently reduced.

The configurations of the "mixer" and the "electrolyzed water generator" are not limited to the examples of the configurations of the electrolytic cell 10 (mixing unit 10b) and the electrolyzed water generator 1 described above. For example, a mixing portion 10b having a partition portion 21c provided with four communication holes 37 has been described as an example, but the number of [communication holes] provided in the “partition portion” is not limited to this, and one or more. It can be specified in any number. Further, the shape of the "communication hole" is not limited to a round hole such as the communication hole 37, and can be defined as any shape such as an elliptical hole, a triangular hole, a rectangular hole, and a polygonal hole. In addition, the configuration in which the electrolytic cell main body 10a corresponding to the "electrolytic cell" and the mixing section 10b corresponding to the "mixer" are integrally formed has been described as an example, but the "electrolytic cell" and the "mixer" have been described. Can also be formed as a separate body.
