The present invention relates to a device for separating acidic ionized water and alkaline ionized water.

[0002]

2. Description of the Related Art Devices for separating water into alkaline ionized water and acidic ionized water have been developed. Alkaline ionized water exhibits excellent solubilizing power and penetrating power, in addition to the swelling action that softens the product. Acidic ion water has a cleaning action,
It has excellent bactericidal and bleaching properties. Taking advantage of these effects, alkaline ionized water is used for drinking water, water for water splitting, water for cohesion and tea. Further, acidic ionized water is used as boiling water for noodles, boiling water for beans, washing water for fruits and vegetables, boiling water for eggs, cleaning water, and the like.

Alkaline ionized water and acidic ionized water are
It is obtained by providing positive and negative electrodes in the water passage and electrolyzing water at the electrodes. Negative ions such as chlorine and sulfur contained in water are electrically sucked into the + electrode, and calcium ions contained in water are contained in the-electrode.
Positive ions such as sodium ions, magnesium ions or potassium ions are attracted. Therefore, +
The water drained from the vicinity of the electrode becomes acidic ion water containing many negative ions, and the water drained from the vicinity of the electrode becomes alkaline ion water containing a large amount of positive ions.

The electrolyzed ionized water producing apparatus is roughly classified as follows.
There are two structures, continuous flow type and pumping type. The continuous flowing type electrolytic ionized water generator is used by being connected to the tap of the water supply. In this device, an electrolytic bath is connected to a tap of a tap, and the tap water is separated into alkaline ionized water and acidic ionized water by the electrolytic bath and drained from separate outlets. Therefore, the device of this system can be conveniently used because the faucet can be opened to use the ionized water. The pumping-type electrolytic ionized water generator puts water in a tank and separates it into acidic ionized water and alkaline ionized water. In this device, the tank is partitioned by a bisque-fired partition. A + electrode and a-electrode are provided in the partitioned portion, and the electrodes are energized to separate them into alkaline ionized water and acidic ionized water. The compartment with the + electrode becomes acidic ionized water, and the compartment with the − electrode becomes alkaline ionized water. A device of this construction can be used without connecting the device to a tap. Therefore, it has the feature that it can be installed easily without the need for installation work.

[0005]

The continuous flowing type electrolytic ionized water generator has a feature that it can be conveniently used because the ionized water can be drained by opening the faucet, but it is necessary to connect it to the faucet of the water supply in a watertight manner. However, there is a drawback that the installation work is troublesome. In particular, water faucets have a wide variety of shapes and require a huge number of attachments with different structures to connect to all shapes of faucets. Further, a major drawback that the device of this structure cannot solve in principle is that high-concentration ionized water cannot be obtained because water is passed through the electrolytic cell once to be separated. In order to make the concentration of separated ionized water as high as possible, the device of this structure uses an extremely large capacity power supply. A large electrolytic ionized water generator uses a transformer as large as 200 to 300 VA. For this reason, there is a drawback that the power source becomes expensive and the total weight becomes significantly heavy.

The pumping-type electrolytic ionized water generator does not need to be connected to a tap. However, this device has the disadvantage that it takes a considerable amount of time to separate the water.
This is because an electrode is provided in the tank divided by the unglazed partition wall, and the water stored in the tank is directly separated into ionic water and stored. Therefore, this device cannot be drunk immediately after filling the tank with water. Further, the electrolytic ionized water generator of this system, when the power is turned off after separating the water into alkaline ionized water and acidic ionized water,
There is a drawback that the concentrations of alkaline ionized water and acidic ionized water gradually decrease. This is because positive ions and negative ions pass through the partition wall and are neutralized.

Embodiments of the present invention will be described below with reference to the drawings. However, the examples shown below exemplify an electrolytic ionized water generator for embodying the technical idea of the present invention, and the electrolytic ionized water generator of the present invention is:
The material, shape, structure, and arrangement of the components are not specified in the structure below. The device of the present invention can be variously modified based on the scope described in the claims. Further, in this specification, for easy understanding of the claims, the numbers corresponding to the members shown in the examples are
It is added to the members shown in the "claim column", the "means for solving conventional problems" and the "action column". However, the members shown in the claims are not limited to the members of the embodiment.

The electrolytic ionized water producing apparatus shown in FIGS. 1 and 2 comprises a water supply tank 1, an alkaline tank 6, a water purification tank 5, a circulation pump 2, an electrolytic tank 3 and an acidic tank 4. ing.

In the apparatus shown in FIG. 1, the water supply tank 1 and the alkaline tank 6 are provided in one tank 15. The tank 15 is watertightly divided into a water supply tank 1 and an alkaline tank 6 by a flexible sheet 16. The tank 15 is open at the top. This tank 15 can supply water to the water supply tank 1 through the upper opening. Further, the alkaline tank 6 can supply the alkaline ionized water from the upper opening, and can also pump out the alkaline ionized water from this.

Flexible sheet 1 for partitioning the tank 15
For 6, a sheet through which water and ions do not pass, for example, a synthetic resin sheet or the like is used. Flexible sheet 16
When either one of the water supply tank 1 and the alkaline tank 6 is filled with water, is deformed like a chain line. Therefore, the tank 15 having this structure can be downsized and the capacities of the water supply tank 1 and the alkaline tank 6 can be increased. This is because the flexible sheet 16 can be deformed to increase one volume. Both the water supply tank 1 and the alkaline tank 6 are not filled with water. This is because the water discharged from the water supply tank 1 is separated into ionized water in the electrolytic tank 3 and then supplied to the alkaline tank 6. That is, when the water in the water supply tank 1 decreases, the amount of ionized water in the alkali tank 6 increases.

The tank 15 has a capacity of, for example, 1 to 10 liters. In the tank 15 shown in FIG. 1, the discharge side of the water supply tank 1 is connected to the electrolytic cell 3 via the water purification tank 5 and the circulation pump 2. The discharge side of the alkaline tank 6 is directly connected to the circulation pump 2. The device of this structure is a water tank 1.
The water is passed through the water purification tank 5 and supplied to the electrolytic tank 3. The alkaline ionized water stored in the alkaline tank 6 is sucked into the circulation pump 2 without passing through the water purification tank 5. This apparatus has a feature that the concentration of ionized water can be increased by using, for the water purification tank 5, one that removes components dissolved in water, such as activated carbon. This is because no matter how many times the alkaline ionized water stored in the alkaline tank 6 is circulated, the water passes through the water purification tank 5 only once.

In the apparatus shown in FIG. 2, the water supply tank 1 and the alkaline tank 6 are connected to the suction side of the circulation pump 2. The discharge side of the circulation pump 2 is connected to the electrolytic cell 3 via the water purification tank 5. The apparatus having this structure can filter the circulating alkaline ionized water many times by the water purification tank 5. For this reason,
The water purification tank 5 has a feature that alkaline ionized water can be filtered more clearly. However, the filter medium of the water purification tank 5 used at this position is preferably one that does not remove ions contained in water or one that has a low ion removal capability. This is because when the filter medium of the water purification tank 5 removes the ions contained in the water, the ion concentration of the alkaline ionized water becomes low. The water purification tank 5 connected to this position is
As the filter material, for example, a material that mechanically filters foreign matter contained in water, such as a nonwoven fabric or an open-cell synthetic resin foam, is used.

The circulation pump 2 comprises a water supply tank 1 and an alkali tank 6
Water is inhaled from and supplied to the electrolytic cell 3. The suction side of the circulation pump 2 is connected to the water supply tank 1 and the alkaline tank 6 via a float valve 17. The float valve 17 is provided on the bottom discharge side of the water supply tank 1 and the alkaline tank 6. The float valve 17 opens when there is water, and closes when there is no water. Circulation pump 2 with a float valve 17 connected to the suction side
First inhales water from the water supply tank 1. The water sucked from the water supply tank 1 passes through the electrolytic tank 3 and is supplied to the alkaline tank 6. After the water is supplied to the alkaline tank 6, the circulation pump 2 sucks the water from both the water supply tank 1 and the alkaline tank 6. When the water in the water supply tank 1 is used up, the circulation pump 2 sucks ion water only from the alkaline tank 6 and circulates the alkaline ion water in the electrolytic tank 3.

In the apparatus shown in FIG. 2, the suction side of the circulation pump 2 is connected to the water supply tank 1 and the alkaline tank 6 via a switching valve 18. The switching valve 18 connects the suction side of the circulation pump 2 to
Either the water supply tank 1 or the alkaline tank 6 is switched and connected. As shown in FIG. 2, when the switching valve 18 connects the circulation pump 2 to the water supply tank 1, water is sucked from the water supply tank 1. When the switching valve 18 connects the circulation pump 2 to the alkaline tank 6,
The circulation pump 2 sucks alkaline ionized water from the alkaline tank 6. This device first connects the switching valve 18 to the water tank 1 side. After all the water in the water supply tank 1 is separated into alkaline ionized water and acidic ionized water, the switching valve 18 connects the circulation pump 2 to the alkaline tank 6. When the circulation pump 2 is connected to the alkaline tank 6, the ion water in the alkaline tank 6 is circulated to the electrolytic tank 3 and its concentration gradually increases.

The operating time of the circulation pump 2 is controlled by a timer (not shown) or a pH meter (not shown). The timer sets the operating time of the circulation pump 2 to the time when alkaline ionized water having a predetermined concentration is stored in the alkaline tank 6. The pH meter is the pH of the alkaline tank 6.
Is detected and the operation of the circulation pump 2 is controlled. The circulation pump 2 is operated when the pH of the alkaline tank 6 is lower than the set value, and when the pH is equal to or higher than the set value, the operation of the circulation pump 2 is stopped.

The electrolytic cell 3 is shown in FIG. The electrolysis tank 3 shown in this figure electrolyzes water to separate it into alkaline ionized water containing positive ions and acidic ionized water containing negative ions. The acidic ionized water ionized in the electrolysis tank 3 is supplied to the acidic tank 4, and the alkaline ionized water is supplied to the water supply tank 1.
Is returned to. The output side of the electrolytic cell 3 is branched into two, one is connected to the water supply tank 1 and the other is connected to the outlet 14. A valve 19 that can be opened and closed like a faucet is connected to the outlet 14. When the circulation pump 2 is operated and the valve 19 is opened, the alkaline ionized water can be taken out from the outlet 14. When a sufficiently high concentration of alkaline ionized water is stored in the water supply tank 1, it is not necessary to apply a voltage to the electrodes when opening the valve 19. When the alkaline ionized water concentration in the water supply tank 1 is low, a voltage is applied to the electrodes to discharge the alkaline ionized water from the outlet 14. In this way, the device for taking out the alkaline ionized water from the discharge side of the electrolytic cell 3 can open the valve and operate the circulation pump 2 to take out the alkaline ionized water. However, this invention does not specify the extraction structure of alkaline ionized water in this state. As shown in FIG. 1, a structure in which an alkaline ionized water outlet 20 with a valve is provided in a water supply tank 1, a circulation pump 2
, A structure in which a discharge valve 21 is provided on the discharge side, a structure in which a discharge pump is provided at the outlet of the alkaline tank 6, and
A structure in which a part of the alkaline tank is opened and ion water is pumped out from the opening can also be adopted.

The electrolytic cell 3 is provided with a positive electrode 7 for making the inflowing water into acidic ionized water and a negative electrode 8 to make it into alkaline ionized water. Further, the electrolytic cell 3 is connected to an alkaline ionized water drainage channel 9 and an acidic ionized water drainage channel 10 for discharging alkaline ionized water and acidic ionized water separated by electrodes. -The electrode 8 is also used as a case. The case is made of a conductive and corrosion-resistant metal such as stainless steel, and is formed into a cylindrical tank type having a strength to withstand the pressure of tap water. The case has a connecting pipe of the water purification tank 5 at the lower end, and has an alkaline ionized water drainage channel 9 and an acidic ionized water drainage channel 10 at the upper end.

The + electrode 7 is formed in a cylindrical shape and is provided at the center of the case. Negative ions such as chlorine ions collect on the + electrode 7 during electrolysis. + Electrode 7
Is made of a material having sufficient corrosion resistance to chlorine ions. For the + electrode 7, for example, a titanium surface coated with iridium dioxide can be used. +
Both ends of the electrode 7 are insulated and protrude to the outside of the case. A non-conductive material (not shown) is used for the supporting portion of the + electrode 7 of the case. The + electrode 7 and the − electrode 8 are connected to a DC power supply 12. The output voltage of the power supply 12, that is,
The voltage between both electrodes is determined in consideration of the flow rates of the alkaline ionized water and the acidic ionized water, the electrode area, and the required ion concentration contained in the alkaline ionized water and the acidic ionized water. Normally, the voltage between both electrodes is adjusted in the range of 10 to 100 volts. The content of ions ionized in the electrolytic cell 3 is proportional to the current between the electrodes. The current between the electrodes is approximately proportional to the voltage. Therefore, the ion concentration contained in the alkaline ionized water and the acidic ionized water can be adjusted by the voltage between the electrodes. The higher the voltage between the electrodes, the higher the concentration of ions contained in the alkaline ionized water and the acidic ionized water. Electric power is supplied to the electrodes from the power supply while the circulation pump 2 is operating. When the operation of the circulation pump 2 is stopped, no voltage is applied to the electrodes.

A perforated plate 13 is disposed between the + electrode 7 and the − electrode 8 as shown by the chain line. The porous plate 13 is formed in a cylindrical shape and prevents the acidic ion water and the alkaline ion water separated near the + electrode 7 and the − electrode 8 from mixing with each other. The alkaline ionized water drainage channel 9 is connected to the center of the plate material that closes the upper end of the porous plate 13. The acidic ionized water drainage channel 10 is opened at the upper end of the outer peripheral portion of the case.

Both the alkaline ionized water and the acidic ionized water flowing out from the electrolytic cell 3 are discharged at the same time. The flow rate of alkaline ionized water is 2 to 15 times that of acidic ionized water.
It is adjusted to double, preferably 2.5 to 5 times. This is because this type of apparatus mainly uses alkaline ionized water, so that the alkaline ionized water is circulated many times to gradually increase the concentration, in other words, increase the pH.

The acidic tank 4 stores the acidic ionized water separated in the electrolytic tank 3. The flow rate of acidic ionized water is adjusted to a fraction of the flow rate of alkaline ionized water. Therefore, the acid tank can be smaller than the water supply tank. Water tank and acid tank
Although not shown, the structure is such that it can be easily attached and detached. The removable water tank and acid tank can be removed from the device to replenish water, and the accumulated water can be drained.
