However, in the electrolyzed water generator described in Patent Document 1, scales such as calcium are precipitated in the cathode chamber of the first electrolysis unit accompanying the electrolysis of water. In addition, the scale precipitated in the cathode chamber of the first electrolysis section adheres to the water channel on the downstream side of the cathode chamber of the first electrolysis section, thereby obstructing smooth water flow. That is, the scale not only adheres to the cathode chamber of the second electrolysis section, but also adheres to the water channel for connecting the cathode chamber of the first electrolysis section and the cathode of the second electrolysis section, which may hinder the above-mentioned alkaline water. Flow smoothly.

The present invention is proposed in view of the above circumstances, and its main purpose is to provide an electrolyzed water generator that can suppress the adhesion of scale and generate electrolyzed water with a high concentration of hydrogen dissolved at a pH suitable for drinking.

Each second electrode chamber is connected in series with a second water channel to generate neutral electrolyzed water in the second electrode chamber located on the upstream side of the second water channel, and alkali is generated in the second electrode chamber located on the downstream side of the second water channel Electrolyzed water.

In the electrolyzed water generating device according to the present invention, it is preferable that the direction of water flow in each second electrode chamber is the same.

In the electrolyzed water generator according to the present invention, it is preferable that the electrolysis chambers are arranged side by side in a direction perpendicular to the direction of the water flow.

The electrolyzed water generator of the present invention includes a plurality of electrolysis chambers for electrolyzing water, and generates neutral electrolyzed water in the second electrode chamber located on the upstream side of the second water channel. Since precipitation of scale does not occur in the second electrode chamber on the upstream side, it is possible to suppress adhesion of scale in the second electrode chamber on the upstream side and the second water channel. In addition, neutral electrolyzed water in which hydrogen gas generated by the electrolysis of water is dissolved is generated in the second electrode chamber on the upstream side.

On the other hand, in the second electrode chamber located on the downstream side of the second water channel, the dissolved hydrogen concentration is increased by the electrolysis of water, and reduced alkaline electrolyzed water is produced.

Hereinafter, an embodiment of the present invention will be described based on the drawings.

Fig. 1 shows a schematic configuration of the flow path of the electrolyzed water generator 1 as an embodiment of the present invention. The electrolyzed water generator 1 is used to generate domestic drinking water, for example.

The electrolyzed water generator 1 includes a plurality of electrolytic cells 3, 4, .... Fig. 1 shows an electrolyzed water generator 1 provided with a pair of electrolytic cells 3 and 4. The electrolyzed water generator 1 may have three or more electrolytic cells 3, 4,...

The electrolytic cell 3 and the electrolytic cell 4 are connected in series. The electrolytic cell 3 is installed on the upstream side with respect to the electrolytic cell 4.

The electrolysis cell 3 has: an electrolysis chamber 30 for electrolyzing water; a first power supply body 31 and a second power supply body 32 that are arranged opposite to each other in the electrolysis chamber 30; and a diaphragm 33 for dividing the electrolysis chamber 30 into The first electrode chamber 30A on the side of the first power supply body 31 and the second electrode chamber 30B on the side of the second power supply body 32.

One of the first power supply body 31 and the second power supply body 32 is used as an anode power supply body, and the other power supply body is used as a cathode power supply body. By supplying water to both the first electrode chamber 30A and the second electrode chamber 30B of the electrolysis chamber 30, and applying a DC voltage to the first power supply body 31 and the second power supply body 32, electrolysis of water is generated in the electrolysis chamber 30 .

The diaphragm 33 of the electrolysis chamber 30 on the upstream side uses, for example, a solid polymer membrane made of a fluororesin having a sulfonic acid group. Plated layers made of platinum are formed on both sides of the diaphragm 33. On the other hand, as the first power supply body 31 and the second power supply body 32, for example, a power supply body in which a platinum plating layer is formed on a mesh metal surface such as an expanded alloy made of titanium or the like is used. The first power supply body 31 and the second power supply body 32 of such a net shape can hold the diaphragm 33 while allowing water to spread over the surface of the diaphragm 33, thereby promoting electrolysis in the electrolysis chamber 30.

The plating layer of the diaphragm 33 abuts and is electrically connected to the first power supply body 31 and the second power supply body 32. The diaphragm 33 passes ions generated by electrolysis. The first power supply body 31 and the second power supply body 32 are electrically connected via a diaphragm 33. In the electrolysis chamber 30 using the diaphragm 33 made of a solid polymer material, the pH value of the electrolyzed hydrogen water does not increase, that is, the water in the electrolysis chamber 30 is kept neutral while electrolysis is performed.

Hydrogen and oxygen are generated by electrolyzing water in the electrolysis chamber 30. For example, in the case where the first power supply 31 is used as the anode power supply, oxygen is generated in the first electrode chamber 30A, and neutral electrolytic oxygen water in which oxygen is dissolved is generated. On the other hand, hydrogen gas is generated in the second electrode chamber 30B, and neutral electrolytic hydrogen water in which the hydrogen gas is dissolved is generated. In the case where the first power supply body 31 is used as the cathode power supply body, hydrogen gas is generated in the first electrode chamber 30A, and neutral electrolytic hydrogen water in which the hydrogen gas is dissolved is generated. On the other hand, oxygen is generated in the second electrode chamber 30B, and neutral electrolyzed oxygen water in which oxygen is dissolved is generated.

The electrolytic cell 4 has: a first power supply body 41 and a second power supply body 42 which are arranged opposite to each other in the electrolysis chamber 40 for electrolyzing water; and a diaphragm 43 for dividing the electrolysis chamber 40 into the first power supply body The first electrode chamber 40A on the 41 side and the second electrode chamber 40B on the second power supply body 42 side.

One of the first power supply body 41 and the second power supply body 42 is used as an anode power supply body, and the other power supply body is used as a cathode power supply body. By supplying water to two of the first electrode chamber 40A and the second electrode chamber 40B of the electrolysis chamber 40, and applying a DC voltage to the first power supply body 41 and the second power supply body 42, electrolysis of water is generated in the electrolysis chamber 40 .

The diaphragm 43 is configured of, for example, a polytetrafluoroethylene (PTFE) hydrophilic membrane. For the first power supply body 41 and the second power supply body 42 arranged to face each other with the diaphragm 43 interposed therebetween, metal plates such as titanium are used. The first power supply body 41 and the second power supply body 42 are arranged at positions separated by a diaphragm 43.

In the electrolytic cell 4 of the above-mentioned structure, as the pH value of the electrolyzed hydrogen water increases, that is, as the alkalinity strength of the water in the cathode chamber increases, an electrolysis signal is sent out.

In the case where the first power supply body 41 is used as the anode power supply body, oxygen is generated in the first electrode chamber 40A, and acidic electrolyzed oxygen water in which oxygen is dissolved is generated. On the other hand, hydrogen gas is generated in the second electrode chamber 40B, and alkaline electrolyzed hydrogen water in which the hydrogen gas is dissolved is generated. In the case where the first power supply body 41 is used as the cathode power supply body, hydrogen gas is generated in the first electrode chamber 40A, and alkaline electrolyzed hydrogen water in which the hydrogen gas is dissolved is generated. On the other hand, oxygen is generated in the second electrode chamber 40B, and acidic electrolyzed oxygen water in which oxygen is dissolved is generated.

The electrolyzed water generating device 1 has a water supply channel 20 for supplying water to be electrolyzed to the electrolysis chambers 30 and 40 and drain channels 61 and 62 for discharging the electrolyzed water from the electrolysis chambers 30 and 40.

Raw water is supplied from the water supply channel 20 to the electrolytic water generator 1. Although tap water is usually used as raw water, other than that, for example, well water, ground water, etc. can be used. In the case where the electrolyzed water generator 1 is used to generate drinking electrolyzed hydrogen water or the like, a water purification box or the like for purifying raw water may be appropriately installed in the water supply channel 20.

The water supply channel 20 branches into a water supply channel 21 and a water supply channel 22. The water supply channel 21 is connected to the lower end of the first electrode chamber 30A. The water supply channel 22 is connected to the lower end of the second electrode chamber 30B. The water flowing into the water supply channel 20 passes through the water supply channels 21 and 22, and then flows into the first electrode chamber 30A and the second electrode chamber 30B.

The drain 61 is connected to the upper end of the first electrode chamber 40A. In the electrolytic cell 4 shown in FIGS. 2 and 4, the drain channel 61 is connected to the first electrode chamber 40A via the water channel 53 formed on the second side wall 4W of the electrolytic cell 4. As a result, the water flowing out of the first electrode chamber 40A flows into the drain 61.

The drain 62 is connected to the upper end of the second electrode chamber 40B. In the electrolytic cell 4 shown in FIGS. 3 and 5, the drain 62 is connected to the second electrode chamber 40B via a water channel 54 formed on the second side wall 4W of the electrolytic cell 4. As a result, the water flowing out of the second electrode chamber 40B flows into the drain 62.

The electrolysis current supplied to the power supply bodies 31, 32 and the power supply bodies 41, 42 is controlled by a control unit (not shown). The control unit manages the control of the power supply bodies 31 and 32 and the power supply bodies 41 and 42 and other parts. The control unit has, for example, a CPU (Central Processing Unit, central processing unit), a memory, etc., where the CPU executes various arithmetic processing and information processing, etc., and the memory stores programs and various information used for the operation of the CPU.

The control unit controls the polarities of the first power supply bodies 31, 41 and the second power supply bodies 32, 42, for example.

By changing the polarities of the first power supply bodies 31, 41 and the second power supply bodies 32, 42 to each other, it is possible to discharge the desired electrolyzed water in the electrolyzed hydrogen water or the electrolyzed oxygen water from the drain 61, and discharge the non-volatile water from the drain 62. The required electrolyzed water. In addition, it is possible to suppress the adhesion of scale in the electrolysis chamber 30 and the electrolysis chamber 40 by equalizing the time during which the first power supply bodies 31 and 41 and the second power supply bodies 32 and 42 function as anode power supply bodies or cathode power supply bodies.

Hereinafter, the case where the first power supply bodies 31 and 41 are used as anode power supply bodies is described without prior explanation. The description is also applicable to the case where the first power supply bodies 31 and 41 are used as cathode power supply bodies. .

The control unit, for example, performs feedback control on the DC voltages applied to the power feeders 31 and 32 and the power feeders 41 and 42 based on the hydrogen dissolved concentration set in advance so that the electrolysis current becomes a desired value. For example, when the electrolysis current is too large, the control unit lowers the voltage, and when the electrolysis current is too small, the control unit increases the voltage. Thereby, the electrolysis current supplied to the power supply bodies 31, 32 and the power supply bodies 41, 42 can be appropriately controlled.

The first electrode chamber 30A of the electrolysis chamber 30 and the first electrode chamber 40A of the electrolysis chamber 40 are connected in series through the first water channel 51. In addition, the second electrode chamber 30B of the electrolysis chamber 30 and the second electrode chamber 40 of the electrolysis chamber 40 The electrode chambers 40B are connected in series through the second water channel 52. In this way, since the second electrode chamber 30B for generating neutral electrolyzed water and the second electrode chamber 40B for generating alkaline electrolyzed water are connected in series through the second water channel 52, even if the electrolysis is increased in order to increase the dissolved hydrogen concentration. In the case of electric current, the pH value of the electrolyzed water can be prevented from increasing excessively. Therefore, electrolyzed water with a high dissolved hydrogen concentration can be produced at a pH suitable for drinking.

In addition, in the case where the first power supply bodies 31, 41 are used as anode power supply bodies, that is, when the first electrode chambers 30A, 40A are used as anode chambers, it is also possible to communicate in parallel through the first water channel 51. The first electrode chamber 30A and the first electrode chamber 40A are constructed. In this case, since oxygen generated in the first electrode chamber 30A does not flow into the first electrode chamber 40A, it is also possible to sufficiently supply water to the surface of the first power supply body 41. Therefore, electrolysis can be efficiently performed in the electrolysis chamber 40, and the dissolved hydrogen concentration can be increased.

The electrolysis chamber 30 is arranged on the upstream side of the second water channel 52, and the electrolysis chamber 40 is arranged on the downstream side of the second water channel 52. That is, the second electrode chamber 30B for generating neutral electrolyzed water is arranged on the upstream side of the second water channel 52, and the second electrode chamber 40B for generating alkaline electrolyzed water is arranged on the downstream side of the second water channel 52. side. Thereby, precipitation of scale does not occur in the second electrode chamber 30B located on the upstream side, and the adhesion of scale in the second electrode chamber 30B and the second water channel 52 can be suppressed. In addition, neutral electrolyzed water in which hydrogen gas generated by the electrolysis of water is dissolved is generated in the second electrode chamber on the upstream side.

On the other hand, in the second electrode chamber 40B located on the downstream side of the second water channel 52, the dissolved hydrogen concentration is increased by the electrolysis of water, and reduced alkaline electrolyzed water is produced. Along with this, although scale is deposited with electrolysis in the second electrode chamber on the downstream side, the adhesion area of the scale is limited to the water channel on the downstream side than the second electrode chamber 40B, so that countermeasures for the scale can be easily taken. . For example, by setting the cross-sectional area of the water channel on the downstream side of the second electrode chamber 40B to a larger area, etc., it is possible to It is easy to perform scale countermeasures. Therefore, while suppressing the adhesion of scale, "electrolyzed hydrogen water" with high dissolved hydrogen concentration can be produced at a pH suitable for drinking.

As indicated by arrows 30X and 40X, the direction of water flow in each of the first electrode chambers 30A and 40A is the same. In this embodiment, the water flow directions 30X, 40X in the first electrode chambers 30A, 40A are vertical directions from the lower end to the upper end of the first electrode chambers 30A, 40A. Therefore, since the water flow directions 30X, 40X in the first electrode chambers 30A, 40A coincide with the moving directions of oxygen generated in the first electrode chambers 30A, 40A, oxygen can be efficiently discharged from the first electrode chambers 30A, 40A. As a result, it is possible to suppress the oxygen generated in the first electrode chambers 30A and 40A from staying on the surfaces of the first power supply bodies 31 and 41. Therefore, it is also possible to sufficiently supply water to the surfaces of the first power supply bodies 31, 41, so that electrolysis can be efficiently performed in the electrolysis chambers 30, 40 and the hydrogen dissolved concentration can be increased.

As indicated by arrows 30Y and 40Y, the direction of the water flow in each of the second electrode chambers 30B and 40B is the same. In this embodiment, the water flow directions 30Y, 40Y in the second electrode chambers 30B, 40B are vertical directions from the lower end to the upper end of the second electrode chambers 30B, 40B. Therefore, since the water flow directions 30Y and 40Y in the second electrode chambers 30B and 40B coincide with the moving directions of the hydrogen gas generated in the second electrode chambers 30B and 40B, the hydrogen gas can be efficiently discharged from the second electrode chambers 30B and 40B. As a result, it is possible to suppress the hydrogen gas generated in the second electrode chambers 30B and 40B from staying on the surfaces of the second power supply bodies 32 and 42. Therefore, it is also possible to sufficiently supply water to the surfaces of the second power supply bodies 32 and 42, so that electrolysis can be efficiently performed in the electrolysis chambers 30 and 40 and the hydrogen dissolved concentration can be increased.

Preferably, the electrolysis chambers 30 and 40 are arranged side by side in a direction perpendicular to the water flow directions 30X, 40X, 30Y, and 40Y. In this method, it is easy to control the height of the electrolyzed water generator 1 and achieve a low height.
