[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device which can be connected to a tap water tap of a general household and used to selectively generate electrolytic water and oxidizing potential water.

[0002]

2. Description of the Related Art After removing odors, coloring components, pollutants, chlorine for sterilization and the like contained in raw water such as tap water through a filtration device such as activated carbon, a chemical solution which is useful for health is aforesaid. After adding to the raw water, it is supplied to a closed electrolytic cell, and a direct current is passed between the separated negative and positive electrodes via the ion-permeable diaphragm in the electrolytic cell to perform electrolysis of water and ionic permeation, There is an electrolyzed water producing apparatus that produces alkaline water on the side and acidic water on the anode side, and discharges this to different outlets to use the alkaline water for drinking and the like and to use the acidic water for the astringent solution and the like.

For example, in the household continuous electrolyzed water generator shown in FIG. 6 and the apparatus of Japanese Utility Model Publication No. 3-123595, an inflow passage, an outflow passage, and an electrolyzer of feed water, which are the components housed in the box 5, are provided. A flow path control unit 9 which is a collection of inflow and outflow paths to and from a drainage port for removing unnecessary water, and a water purifier 7 that allows all raw water to pass through and removes raw water pollutants,
Raw water is supplied to the electrolytic cell 3 through an auxiliary agent adder 6 for adding an electrolysis accelerator to a part of the raw water that has passed through the water purifier, and an electrode of the electrolytic cell for varying the electrolytic strength (not shown). Electrolysis is performed with a means for varying the voltage applied to the electrode and a mechanism for reversing the polarity, and alkaline water discharged from the cathode chamber is discharged through the discharge pipe 8 and unnecessary water used for cleaning the electrode chamber is flowed. Draining through control unit.

Separately, an electrolyte such as salt is added at a constant ratio to raw water such as tap water and the mixture is introduced into a closed electrolytic cell, which is separated through an ion-permeable diaphragm in the electrolytic cell. A direct current is passed between them to perform electrolysis and ion penetration of water, producing cathode water on the cathode side and anode water on the anode side, draining the cathode water, and disinfecting the anode water with sterilizing water. There is an oxidation potential water generator used as.

It is well known that oxidation potential water is effective as disinfecting and sterilizing water. For example, JP-A 1-228
No. 589 discloses that low-pH anodic water produced by adding salt to raw water is effective as disinfecting and sterilizing water. Moreover, since a sterilizing agent such as an organic sterilizing solution is not added to this oxidizing potential water, it is useful as a reliable disinfecting and sterilizing water because it does not contain harmful substances and has no residue of the agent.

In order to generate such oxidation potential water, an electrolyte, for example, salt has conventionally been required to be replenished, and moreover, a complicated operation such as addition of the electrolyte at a constant ratio has been required. Since it is used as disinfecting and sterilizing water in hospitals and the like, the device is large and difficult to use at home. On the other hand, oxidation potential water for household use, for example,
It is desired to use it as a disinfectant and sterilizing water for washing cutting boards and dishes, washing cloths and hands, and gargle.

[0007]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to provide a device which can be used as a continuous electrolysis water producing device for household use as an electrolysis water producing device and also as a continuous oxidation potential water producing device. It is a thing.

Most of raw water such as tap water originates from surface water such as rivers, and seawater evaporates into rainwater and is immersed in the ground. Therefore, in the process of evaporation, the substance contained in the seawater is mixed with the evaporation or by being scattered and is contained in the tap water. Tap water or the like contains chlorine ions that are such a cause. It is also well known to add chlorine for sterilization. A part of the added chlorine is dissociated to generate Cl ions and hypochlorite ions. In the present invention, the Cl ion or hypochlorite ion is used as an electrolyte, and the amount of raw water flowing into the electrolytic cell is squeezed so as to increase the unit electrification electricity amount so as to be suitable for oxidation potential water generation. Thus, oxidation potential water is obtained without adding an electrolyte.

[0009]

In order to achieve the object, the present invention has a direct current between the cathode and cathode electrodes of the cathode chamber and the anode chamber, which are divided by an ion-permeable diaphragm and in which the cathode and anode are inserted. In an apparatus for applying a voltage and providing an applied voltage varying means for varying the electrolysis strength of an electrolytic cell to electrolyze raw water continuously flowing into the electrolytic cell, the raw water is changed in at least two directions, and at least one of them is changed. Direction flow rate
The flow rate of the raw water, which is provided with a valve body to limit the flow path
A water purifier suitable for removing chlorine ions and hypochlorite ions is attached to at least one flow path that does not limit
At least one flow path that restricts the flow rate is composed of a flow path through which raw water directly flows, and the raw water restricts the above flow rate.
When flowing into the electrolytic cell through the valve, pH is 2.8, ORP
The anode water in the vicinity of 1050 mv is configured to be discharged.

The valve body has a closure rotatably engaged in the outer shell and a through hole for controlling the supply of electrolytic water and raw water necessary for producing oxidizing potential water. The gist is that the through hole of the husband is formed at an angle deviated in the rotating direction.

[0011]

The present invention uses a valve body for switching the flow path of the raw water supplied to the electrolyzer between the production of electrolyzed water and the production of oxidation potential water depending on the use, and the valve body uses the oxidation potential water when the electrolysis water is produced. The generation flow path is closed, and conversely, when the oxidation potential water is generated, the electrolyzed water generation flow path is closed, so that electrolysis water and oxidation potential water can be freely generated as desired. Further, since an electrolyte such as salt required for generating oxidation potential water uses chlorine ions dissolved in water, an electrolyte for generating oxidation potential water and a device for adding the electrolyte are not required.

[0012]

1 and 2 are operation explanatory views of an electrolysis / potential water generator according to the present invention. Members having the same functions and mechanisms as those in FIGS. 3, 4, 5 and 6 are designated by the same reference numerals. 1 and 2 show that the position of the valve body can be freely changed and used according to the arrangement of the members. The effect is the same. Reference numeral 1 is an electrolyzed water production flow path, 2 is an oxidation potential water production flow path, and 3 is a common electrolytic cell of both production devices. Reference numeral 4 is a valve body that switches between the electrolytic water generation flow channel and the oxidation potential water generation flow channel.

When the valve body 4 is switched to the electrolyzed water generation flow path 1, raw water such as tap water is filled with activated carbon or the like for removing chlorine and organic substances such as odors and colorants contained in the raw water. After the organic substances and chlorine are removed by passing through 7,
It flows into the electrolytic cell 3. Here, a DC voltage is applied to the positive and negative electrodes arranged in each of the cathode and anode chambers divided by the partition walls in the electrolytic cell to perform electrolytic action and ion permeation action to perform alkaline action from the cathode chamber and acidic water from the anode chamber. Discharge and use as drinking water and astringent water.

On the other hand, when the valve body 4 is switched to the oxidation potential water generation flow path 2, the amount of raw water such as tap water flowing into the electrolytic cell is narrowed compared to the generation of electrolyzed water, while passing through the water purifier 7. Flows into the electrolytic cell 3 without any action. Here, a DC voltage is applied to the positive and negative electrodes arranged in each of the cathode and anode chambers divided by the partition walls in the electrolytic cell to give an electrolytic action and an ion permeation action to give cathode water from the cathode chamber and oxidation potential water from the anode chamber. Discharges. Oxidation potential water discharged in this state usually has a pH of 2.8 and an oxidation-reduction potential (ORP) of about 1050 mv , and functions sufficiently as disinfection and sterilization water. At this time, the cathode water discharged at the same time is normally discharged, but since it can ensure pH 12 or more, it can be used for various applications requiring a high pH, for example, as an acid neutralizer.

Since the electrolyzed water production flow path 1, the oxidation potential water production flow path 2, the electrolytic bath 3 and the valve body 4 form a closed flow path, when the electrolyzed water production flow path 1 is opened, the oxidation potential is increased. The water generation channel 2 is closed, and conversely, the oxidation potential water generation channel 2 is
When is open, the electrolyzed water generation flow path 1 is closed. Although both flow paths are joined immediately before the raw water inlet of the electrolysis tank, there is no risk of mutual inflow water mixing.

In the above description, the valve body has been described as one that divides two paths for electrolyzed water and oxidation potential water, but it is divided into three or more paths, two paths of which are for electrolyzed water,
Others can be used for the oxidation potential water. in this case,
Water purifiers having different capacities can be attached to the two paths for electrolyzed water. One of the water purifiers is specified by the particle size, for example, it is composed of a member such as a hollow fiber that is suitable for blocking contaminants such as certain particles and bacteria, and the other water purifiers are mainly contained in raw water. A substance containing activated carbon or the like that removes the chemical substance can be attached to the husband.

FIG. 3 is a diagram showing an embodiment of the valve body. The valve body 10 is composed of a rotatable closure 13 which is inserted into and engaged with a hole 12 opened in the outer shell 11. A through hole 14 that functions as an electrolyzed water generation flow path and a through hole 15 that is smaller in diameter than the flow hole 14 that functions as an oxidation potential water generation flow path with a constant deviation angle from the flow hole 14 pass through the closure 13. . Then, it is connected to a driving device 16 such as a pulse motor that can accurately adjust the rotation angle. In the outer shell 11, there are pipe openings 17 and 19 for injecting raw water such as tap water into the circulation holes 14 and 15 of the husband and outflow of supply water passing through the valve body. Although the closure 13 is shown in the shape of a cylinder in the figure, the same action and effect can be obtained even if it has a conical shape.

For example, with respect to the diameter of an arbitrary closure, the diameter of each hole is defined as the diameter of the closure / 2.gtoreq.a.
When the diameters of the flow paths of Nos. 19 and 19 are smaller than the hole diameter ... A, the deviation angle is provided, so that there is a possibility that the closed position where both the flow paths are switched is generated in the closure, and the electrolytic water and the oxidation potential water are mixed. Disappear. Moreover, since the diameter of the through hole 15 is smaller than that of the through hole 14, it is further safe. In this way, when the flow path is switched to the oxidation potential water side, pH 2.8, ORP
Oxidation potential water of about 1050 mv is 800 to 1000 cm
³ / min can be obtained.

FIG. 4 is a view showing another embodiment of the valve body closure. In the figure, an outer shell similar to that shown in FIG. 2 is formed on the valve body, and a rotatable cone-shaped closure 23 is inserted therein. A flow hole 24 that acts as an electrolyzed water generation flow channel and a flow hole 25 that has the same diameter and that acts as an oxidation potential water generation flow channel with a constant deviation angle pass through the closing member 23. The closure 23 is connected to a drive member that can accurately adjust the rotation angle. Various known methods can be used as the driving member.

For example, the voltage applied to the positive and negative electrodes of the electrolytic cell is 25 V, the hole diameter for the electrolyzed water generation flow passage formed in the upper part of the closure 23 is 7 mm, and the hole diameter for the oxidation potential water formed in the lower part is When the flow path is switched to the oxidation potential water side by setting the deviation angle of the respective holes to 111 ° and 7 mm, the same pH value of 2.
8, ORP1050 mv oxidation potential water 800-1
000 cm ³ / min can be obtained.

FIG. 5 illustrates another embodiment of the valve body of the present invention as may be implemented in FIG. The valve body is a rotatable closure 33 having a through hole for controlling the supply of the electrolyzed water and the raw water necessary for generating the oxidation potential water in parallel with the rotation axis of the closure 33 which is inserted and engaged in the outer shell 31. It consists of. Closed 33
A through hole 34 that functions as an electrolyzed water generation flow path and a circulation hole 35 that functions as an oxidation potential water generation flow path with a constant deviation angle from the flow hole 34 penetrate therethrough. Then, it is connected to a driving device 16 capable of accurately adjusting the turning angle that allows the turning to the left and right. In the outer shell 31, raw water such as tap water and raw water from the water purifier flow into the husband's circulation holes 34 and 35, and pipe mouth portions 3 and 39 through which the supply water that has passed through the valve body flows out.
There is 7.

The flow holes 34 and the flow holes 35 are not circular in shape, for example, a persimmon seed shape, and the valve body is simply switched between the electrolytic water generating flow path and the oxidation potential water generating flow path. Instead, it can also function as a flow rate control valve.

In FIG. 1, the raw water inflow passages to the cathode and anode chambers of the electrolytic cell are merged, but these are provided independently, for example, a health agent adder for adding a health agent to the inflow passages to the cathode chamber. Etc. can be arranged freely. These are merely examples, and various modifications can be made within the scope of the present invention other than the embodiments described above.

[0024]

EFFECTS OF THE INVENTION When the raw water supplied to the electrolytic cell is switched between electrolytic water generation and oxidation potential water generation depending on the purpose,
In addition, a valve body that restricts the flow rate in at least one direction is used, and the valve body closes the oxidation potential water generation flow path when electrolytic water is generated, and conversely when the oxidation potential water is generated, electrolytic water generation is performed. Since the flow path is closed, either electrolyzed water or oxidation potential water can be freely generated as desired, regardless of the simple device.

Since the electrolyte such as sodium chloride required for generating the oxidation potential water utilizes chlorine ions dissolved in water, the electrolyte and the addition device thereof are not required for the generation of the oxidation potential water. Therefore, oxidation potential water can be produced at low cost.

By using an electrolysis tank for producing electrolyzed water and oxidation potential water as a common member, the whole apparatus can be constructed compactly, and inspection and repair can be easily performed even in maintenance after installation. .
