Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a multifunctional electrolyzed water generating apparatus which uses tap water as raw water to electrolyze and discharge alkaline ionized water and strongly acidic water as required. More specifically, the present invention relates to a mechanism for obtaining water with stable characteristics when discharging strongly acidic water by adding an electrolyte to raw water, if desired.

[0002]

2. Description of the Related Art In order to remove unsuitable components in beverages contained in raw water, a water purifier is installed before flowing into an electrolytic cell, and raw water such as tap water is supplied to the water purifier to be filtered and purified.
There is an electrolyzed water generator configured to add an alkaline earth metal salt as a mineral component to a flow path leading to an anode chamber of filtered raw water and then flow into an electrolytic cell. The electrolytic cell used for this is divided into a cathode chamber and an anode chamber by an ion-permeable membrane in the electrolytic cell, and a negative electrode and a positive electrode are provided in each chamber. Is electrolyzed by the application of a direct current applied thereto. As a result of the electrolysis of raw water, cathodic water with a high pH is discharged from the cathode chamber,
Of low anode water.

[0003] The cathodic water thus generated replenishes mineral components that are liable to be lacking in the human body, and moderate alkalinity is said to be effective in preventing acidification of the human body, which is preferable for health. It is used mainly as drinking water under the name of alkaline ionized water as the acting water. On the other hand, the anodic water discharged at the same time is used as astringent water or the like.

[0004] Apart from the above alkaline ionized water, a slight amount of chlorine and chlorine ions contained in tap water are positively utilized, or halogens such as NaCl and KCl are used as electrolytes in raw water before supply to the electrolytic cell. When the compound is added at a certain ratio and electrolyzed in an electrolytic cell, low pH anodic water containing hypochlorous acid and the like is obtained from the anode chamber. In particular, those having a pH of 2.7 or less and an ORP of 1100 mV or more have a strong disinfecting and disinfecting effect. It is commercially available as a water generator.

[0005] Electrolyzed water generators for producing alkaline ionized water are mainly used for homes and restaurants because of their use, whereas electrolyzed water generators for generating strongly acidic water are used for medical institutions such as hospitals. Has been the main target of demand,
In terms of sales channels, they have been marketed as dedicated devices. However, since the sterilizing effect of strong acidic water and its safety have been recognized, there is a strong demand in homes and the like to use an electrolyzed water generator for generating strong acidic water for disinfection and sterilization. The use of strong acid water at home does not require as much as medical institutions. For this reason, a multifunctional electrolyzed water generating apparatus has been developed which discharges an alkaline ionized water and an appropriate amount of strongly acidic water as desired by using one apparatus.

The apparatus for discharging alkaline ionized water and the apparatus for discharging strongly acidic water have almost the same configuration of the electrolytic cell itself. Therefore, both functions can be obtained by changing the dissolved component of raw water supplied to the electrolytic cell. . In other words, by using the same electrolytic cell and appropriately changing the piping route, the chemical solution to be added, the voltage applied to the electrolytic cell, and the like, sometimes it is used as a device for mainly producing alkaline ionized water, and sometimes it is a strong acid. A multifunctional electrolyzed water generation device that can be used as a device for mainly generating sexual water can be provided.

[0007] As a multifunctional electrolyzed water producing apparatus for producing treated water having different uses, that is, alkaline ionized water and strongly acidic water, using the same apparatus, the same applicant has disclosed in Japanese Patent Application No. 10-327556, a method of adding calcium. The first addition cylinder and the second addition cylinder to which salt is added are interchangeably inserted at the same location, and the first addition cylinder is inserted into the first addition cylinder.
The first electrolyte is supplied when the addition cylinder is inserted, and the second electrolyte is supplied.
When the addition cylinder is inserted, the second electrolyte is supplied, and a switch is provided in the vicinity of the addition cylinder provided below the uppermost part of the electrolytic cell.
The difference between the addition cylinders is identified, the discharge / dissolution amount of the electrolyte is changed to a specific value by the structure of each addition cylinder, and when the first addition cylinder and the second addition cylinder are exchanged, the difference is applied to the negative anode. We proposed a device that inverts the voltage polarity and discharges alkaline ionized water for drinking and strong acidic water for sterilization from the same discharge pipe.

FIG. 6 shows this device. Two types of addition cylinders, a first addition cylinder 8-1 and a first addition cylinder 8-
2 is configured to be detachable with mutual compatibility. In other words, by changing the addition cylinder filled with an alkaline earth metal salt and a strong electrolyte, for example, an addition cylinder filled with salt, one time discharges alkaline ionized water, and another time discharges strongly acidic water. is there. FIG.
FIG. 6A is a diagram illustrating a case of discharging alkaline ionized water, and FIG. 6B is a diagram illustrating a case of discharging strongly acidic water.

In FIG. 6 (a), raw water flows through a water purifier 2, becomes purified water, flows out through a pipe 3, and then reaches a first addition cylinder 8-1 filled with an alkaline earth metal salt. 4 and a pipe 5 flowing into the electrolytic cell. The purified water that has passed through the pipe 4 passes through the first addition cylinder 8-1 and joins the purified water flowing through the pipe 5 at the lower port 11 a via the pipe 7. The purified water flowing through the pipe 5 is supplied to the lower tube opening 11a, 1
Cathode 1 divided from 1b by ion-permeable diaphragm 13
Electrolysis is performed in a cathode chamber 15 provided with a cathode chamber 4 and an anode chamber 17 provided with an anode 16, and cathode water and anode water are discharged from water discharge ports 18 and 19 of the respective pole chambers. In FIG. 6B, the purified water flowing through the pipe 4 branched from the water discharge pipe 3 passes through the second addition cylinder 8-2 and then joins the purified water flowing through the pipe 5 via the pipe 6. Reference numeral 29 denotes a flow sensor for measuring the amount of purified water flowing into the electrolytic cell. By measuring the flow rate on one electrode chamber side, the flow rate in the negative anode chamber can be measured from the negative anode chamber flow ratio.

As shown in FIG. 7, a first addition cylinder 8-1 and a second addition cylinder 8-2 are cylindrical storage containers having substantially the same shape, and are provided with pipes 4, 6, and 7 at their ends. It has target mouths 25, 26, and 27 to be inserted, and the pipe 4, the pipe 6, and the pipe 7
Is removably inserted through the packing 28 by moving in the horizontal direction in the figure. In the addition cylinder 8-1, the hole of the pipe port 26a is closed, and the purified water flowing from the pipe 4 flows from the pipe port 25 to the pipe port 27. Therefore, when the cap 30 is opened and the drug containing calcium is filled in the addition cylinder, the drug dissolves in the purified water and the purified water containing the drug is supplied to the tube opening 2.
Discharge from 7a. Similarly, in the addition cylinder 8-2, the hole of the pipe port 27b is closed, and the purified water flowing from the pipe 4 flows from the pipe port 25 to the pipe port 26b. Therefore, when the salt is inserted into the addition cylinder 8-2, the salt is dissolved in purified water to be converted into a salt solution and discharged from the mouth 26b.

In order to add a required amount of the chemical solution to the predetermined electrolytic chamber from the addition cylinder 8, the first addition cylinder 8-1 and the second
When any one of the addition cylinders 8-2 is used, the flow path and amount of the chemical solution are selectively changed. As shown by the solid line in FIG. 6A, when the first addition cylinder 8-1 is inserted, a part of the purified water that has exited the pipe 3 from the water purifier 2 is supplied to the addition cylinder 8-1 via the pipe 4. After dissolving the calcium agent, it flows into the anode chamber of the electrolytic cell via the pipe 7 and is electrolyzed together with the purified water. In this case, since the pipe 6 indicated by the chain line is closed, it is not substantially involved in the operation. On the other hand, when the second addition cylinder 8-2 is inserted, as shown by the solid line in FIG. 6B, part of the purified water that has exited the pipe 3 from the water purifier 2 dissolves salt in the addition cylinder 8-2. Is returned to the pipe 5 via the pipe 6, and the pipe opening 1
Electrons are branched from 1a and 11b to the anode and cathode bipolar chambers of the electrolytic cell. In this case, as shown by a chain line in FIG.
Is not involved in the operation substantially because it is closed.
When changing from the first addition cylinder 8-1 to the second addition cylinder 8-2, the switch means 9 operates to generate a signal indicating that an electrolyte such as NaCl is to be added, and the polarity of the voltage applied to the electrode is changed. As described above, the alkaline ionized water for drinking and the strong acidic water for sterilization can be discharged from the same discharge pipe as described above.

[0012]

However, in the above apparatus, the supply amount of the raw water is supplied through the same flow path in the case of both alkaline ionized water and strongly acidic water.
The dissolved concentration of the electrolyte in the purified water varies depending on the amount of the electrolyte in the addition cylinder that decreases with the passage of the electrolysis time. In particular, when an electrolyte such as NaCl is inserted into the second addition cylinder, when the electrolyte remains sufficiently in the addition cylinder, the water supplied to the electrolytic tank exhibits high electric conductivity, whereas the electrolyte remaining in the addition cylinder is high. If the amount is small, the concentration of the electrolyte in the purified water will be low, and its electric conductivity will be low. During this time, if the voltage applied to the electrolytic cell is the same, the electrolysis cannot be raised as predetermined, and water having a predetermined electrolysis corresponding to a concentration suitable as sterilizing water, for example, water of ORP1100 or higher at pH 2.7 or lower is discharged. In some cases, the user may not be able to use acidic water effective for sterilization and the like. In particular, when using the device at home, etc., when the second addition cylinder is loaded, the anolyte discharged from the container is assumed to be strong acid water and received in a container for washing hands, etc., without checking the above pH and ORP. Even if it is used, in fact, the strongly acidic water discharged when the electrolyticity is high and the strongly acidic water discharged when the electrolyticity becomes low are mixed, and the strong acidic water in the container does not reach the predetermined value, Inconveniences, such as using water discharge with poor bactericidal properties, occur. In addition, since there is no mechanism for responding to fluctuations in the supply amount of raw water due to fluctuations in water pressure, there is a fluctuation in the load of the electrolytic cell with respect to fluctuations in water pressure, and it is difficult to obtain strong acidic water with stable water quality. There were challenges.

Therefore, the present inventor provided a mechanism for changing the supply amount of raw water between alkaline ionized water and strongly acidic water, provided a water inlet control member at the raw water inflow portion of the electrolytic cell, and controlled the water inlet control member. When discharging strongly acidic water, an optimal electrolytic voltage is applied to the electrode corresponding to the amount of the electrolyte in the addition cylinder filled with the electrolyte, and a current is applied to obtain a strongly acidic water of a desired quality. Accordingly, it is an object of the present invention to provide an economical multifunctional electrolyzed water generating apparatus that discharges stable strongly acidic water.

[0014]

The multifunctional electrolyzed water generating apparatus according to the first aspect of the present invention is a multifunctional electrolyzed water generating apparatus for discharging alkaline ionized water and strongly acidic water as required, and is detachable from raw water. In the method of supplying an electrolyte to the diaphragm type electrolytic cell after adding the electrolyte from the electrolyte addition cylinder, the raw water inflow path is provided with control means for controlling the supply of the raw water in conjunction with the strong acid water spouting.

According to a second aspect of the present invention, there is provided a method for generating electrolyzed water in a multifunctional electrolyzed water generating apparatus, wherein the operation of the control means is performed with a fixed period or intermittently for temporarily increasing the solubility of the electrolyte. It is characterized by the following.

According to a third aspect of the present invention, there is provided the multifunctional electrolyzed water generating apparatus, wherein the applied voltage of the electrolysis voltage is controlled to a predetermined value in accordance with the operation of the control means and the amount of the electrolyte added. .

[0017]

FIG. 1 is a block diagram of a multi-function generating apparatus according to the present invention, which is to be compared with FIG. The same members as those in FIG. 6 are denoted by the same reference numerals, and redundant description will be omitted.

Water inlet control functioning as a control means for controlling the amount of water input corresponding to the type of the electrolytic water to be discharged and the fluctuation of the raw water pressure into the flow path from the connection port 20 for tap water to the water purifier 2. A member 21 is provided. The water inlet control member 21 includes an electromagnetic valve 24 that opens and closes in accordance with the type of the addition cylinder, that is, the type of electrolyzed water, and a constant flow valve 23 that controls the flow rate when discharging strongly acidic water. In the figure, the solenoid valve is a plunger 22-1 which moves as indicated by an arrow by turning on / off a signal from the control means 10 and a valve 2 which opens and closes by moving the plunger for easy understanding.
Although shown by 2-2 itself, other solenoid valves that perform the same function can be used. The solenoid valve 24 is controlled via a control means 10 operated by a signal of the switch means 9, and when the first addition cylinder 8-1 is inserted, the operation is released to reach the water purifier 2 from the pipe opening 20. Open all channels. When the second addition cylinder 8-2 is inserted, the flow path related to the electromagnetic valve is closed so that the raw water reaches the water purifier 2 via the constant flow valve 23.

By this control, the amount of water flowing into the electrolytic cell is reduced even if the second addition cylinder 8-2 is filled with an electrolyte having high electric conductivity due to slight dissolution in water such as NaCl. Therefore, it is possible to discharge the strong electrolyzed water for a predetermined time by setting the current load of the electrolytic cell to a current value substantially equal to the current load at the time of discharging the alkaline ionized water. For example, in the case of home use, in many cases, a strong bucket is used as strong electrolyzed water, for example, with a capacity of about 3 liters. The desired purpose can be achieved by setting the amount of outflow.

Further, even when the generator is used for the purpose of generating strongly electrolyzed water, when it is desired to rapidly dissolve the electrolyte, the control means 10 sends an ON / OFF signal to the water inlet control member 21.
The intermittent flow of the OFF signal causes the amount of water flowing to the addition cylinder to increase or decrease in a time-series manner, dissolves the electrolyte by the impact of the input water pressure, increases the solubility of the electrolyte in the purified water, and temporarily reduces the electricity of the raw water. Conductivity can be increased.

FIG. 2 is a diagram showing an example of a time chart in the case where the solenoid valve 24 of the water inlet control member 21 is opened and closed to dissolve the electrolyte in the addition cylinder in accordance with the formation of the strongly acidic water. In the figure, 10 seconds is set as an initial value in accordance with the time when the raw water at the pipe opening 20 reaches the addition cylinder, and then the intermittent operation is repeated every 3 seconds to give a shock to the electrolyte in the addition cylinder. Then, the solenoid valve 24 is closed. Due to this impact, a predetermined amount of electrolyte can be dissolved in purified water even if the raw water has a low water pressure or the electrolyte is in a lump state and is difficult to dissolve. In the figure, 10 seconds are set as an initial value, and an interval of 3 seconds is set as an impact time. However, an optimum value can be selected for the number of repetitions and the time according to the structure of the apparatus.

The constant flow valve 23 controls the amount of raw water flowing from the pipe opening 20 to the water purifier 2 as the water pressure increases. A known valve can be used as the constant flow valve 23. For example, a constant flow valve or the like disclosed in Japanese Utility Model Laid-Open Publication No. 3-123595, in which water of about 1.5 l / min flows regardless of fluctuations in water pressure, can be suitably used.

[0026] In the vicinity portions crossing the second conduit d _2, the tube opening 31 connected to the inlet water purifier 2 is provided. The second conduit d _2, a portion crossing the third conduit d _3, the water purifier tube opening 32 connected to the outlet of is provided, the inlet of additive pipe 8 to the vicinity of the site 25 Is provided at the front part thereof,
Constant flow control unit 3 that functions in the case of generation of alkaline ionized water
4 is provided, and before that, a cathode chamber side tube opening 11b of the electrolytic cell is provided.

The outlet of the addition tube is connected to join the water flowing into the electrolytic cell 12.

FIG. 4 is a diagram showing an operation flow of the multifunctional electrolyzed water generator for generating strongly acidic water. The main part of the operation shown in the figure is performed via the control means 10.

In the figure, a power switch of a device not shown is turned on 100 and the solenoid valve 24 is opened 10
1 is done. Next, the addition cylinder 8-2 is inserted 102. Prior to the insertion, the water shutoff valve (not shown) is provided with a water stop valve (not shown) to prevent water leakage from the pipe 4 to the pipe opening 25 of the addition cylinder 8-2.
03. To stop water, turn on the power switch of the device.
Prior to zero, it may be performed with a faucet outside the device. As a result, the switch means 9 is turned on 104 and the solenoid valve 24 is closed 105. When the faucet or the like is opened in this state, water flow through the flow path 41 is started 106, and the flow rate sensor 2
9 and the pressure-sensitive switch means 36 are turned on 107, 108
become. At the same time, the voltage applied to the electrolytic cell 12 is set to 10 V to start the electrolysis 109. The solenoid valve is closed 110 regardless of the flow rate for 10 seconds from the start of electrolysis, and after 10 seconds, the solenoid valve is repeatedly opened and closed at intervals of 3 seconds until the electrolysis current reaches a first predetermined value or more 111. When the solenoid valve is closed and the water pressure is low and the amount of water flowing through the water inlet control member is less than a predetermined value, the solenoid valve is opened 112 until the discharge of the strong electrolyzed water ends. When the amount of water flowing through the water inlet control member is equal to or more than a predetermined value, the solenoid valve is closed 113 until the discharge of the strong electrolyzed water ends. In this state, when the electrolysis current is lower than the second predetermined value, the electrolysis applied voltage is shifted up to 114V, and when the electrolysis current is lower than the third predetermined value, the electrolysis applied voltage is shifted up to 20V 115. Then, three minutes after the start of electrolysis 109, the electrolysis is automatically stopped 116.

FIG. 5 is a diagram showing the relationship between the electrolysis time during the generation of strongly electrolyzed water based on the operation flow of strongly acidic water generation and the change in electrolysis current based on the shift up of the voltage applied to the electrolytic cell.

When the control means for reducing the amount of raw water during the production of strongly electrolyzed water is operated and the amount of purified water supplied to the electrolytic cell is reduced, the control means is also controlled in response to the pressure of the supplied raw water. Even if opened and closed, the addition cylinder 8 filled with electrolyte
-2, the concentration of the solution containing the electrolyte flowing out gradually changes. That is, after a predetermined time, for example, 10 seconds, when the purified water flows from the control means to the addition cylinder 8-2, the dissolution of the electrolyte sufficiently filled in the addition cylinder 8-2 starts, and the supply of water supplied to the electrolytic cell starts. The conductivity increases, reaches a first predetermined value, and a current shown in FIG. Then, the current rapidly increases with the dissolution of the electrolyte, reaches the illustrated Q, and then gradually decreases with time in accordance with the consumption of the electrolyte in the addition cylinder 8-2. If the water drops below the imaginary line a after reaching the position R, the anolyte discharged at that time will no longer have a sterilizing effect. Therefore, immediately before the water discharge with which the sterilizing effect is lost, that is, when the water becomes equal to or less than the second predetermined value, the voltage applied between the negative and positive electrodes is increased.
As a result, the amount of the electrolyte in the remaining addition cylinder 8-2 is reduced, and even if the electric conductivity of the water supplied to the electrolytic tank is smaller than that between QR, the S shown in the figure between the negative and positive electrodes of the electrolytic tank. Current flows, and the anodic water discharged has a sterilizing effect. Thereafter, the electrolytic current decreases so as to follow the imaginary line b.
The voltage applied between the negative and positive electrodes of the electrolytic cell is increased so as to be equal to or more than the third predetermined value, and the anode water having a sterilizing effect is maintained so as to be discharged. Further, the voltage may be repeatedly increased up to the current value shown in FIG. In this manner, by increasing the voltage applied to the electrode in accordance with the remaining amount of the electrolyte in the addition tube 8-2 for a predetermined period, the anodic water having a sterilizing effect for a predetermined time is discharged.

The operation time,
The applied voltage and current value can be stored in the control means as appropriate based on the experimental results of the mounting apparatus.

[0033]

According to the present invention, when the electrolyte is added from the addition cylinder of the multifunctional electrolyzed water generating apparatus to generate the strongly electrolyzed water, the control means for controlling the supply of the raw water is provided at the flow distributor inlet. By providing and controlling the supply amount of raw water as compared with the case of alkaline ionized water, it is possible to prevent more electrolyte than desired from flowing into the electrolytic cell and increase the load on the electrolytic power supply. In addition, by appropriately changing the voltage applied to the electrolytic cell in accordance with the change in the supply amount of the electrolyte to the raw water due to the remaining amount of the electrolyte in the electrolytic tube, the sterilizing property can be obtained during a predetermined water discharge period without constantly monitoring the water discharge characteristics. Spitted spout can be obtained reliably. As a result, there is no inconvenience such as using water discharge with poor sterilization.

It is possible to reduce fluctuations in the load on the electrolytic cell with respect to slight fluctuations in the supply amount of raw water due to fluctuations in water pressure or the like, and to easily obtain strong acidic water having stable water quality.
