The present invention relates to an ion water generator.

[0002]

2. Description of the Related Art In recent years, ion water generators have become widespread, reflecting the "health boom". This ion water generator electrolyzes tap water or the like in an electrolytic cell to generate acidic ion water on the anode side and alkaline ion water on the cathode side.

A conventional continuous electrolysis type ionized water generator will be described. FIG. 6 is a schematic overall view of a conventional ionized water generator. 1 is a raw water pipe such as tap water, 2 is a faucet,
Reference numeral 3 is an ion water generator connected to the raw water pipe 1 via the faucet 2. Reference numeral 4 is a water purifier having activated carbon or a hollow fiber membrane inside, 5 is a solenoid valve opened / closed by a signal from a controller described later, 6 is a flow rate sensor for confirming water flow and instructing the controller to start control, 8 Is a diaphragm that divides the electrolytic cell 7 for electrolyzing water that has passed through the flow rate sensor 6 into a cathode chamber 7a and an anode chamber 7b, and 9 and 10 are formed by dividing the electrolyte chamber 7 into two parts, a cathode chamber 7a and an anode. Electrodes disposed in the chamber 7b, 11,
12 and 13 are raw water supply pipes, 13a is a water supply channel to the cathode chamber, 13b is a water supply channel to the anode chamber, and 14 is treated water on the electrode 9 side (when the electrode 9 is a cathode, it becomes alkaline ionized water). Alkaline ionized water discharge passage, 15 is treated water on the electrode 10 side (when the electrode 10 is an anode, it becomes acidic ionized water)
The acidic ionized water discharge passage for discharging water, 16 is a fixed throttle portion for adjusting the flow rate provided in the water supply passage 13b to the anode chamber 7b, 17 is a controller for controlling the operation of the ionized water generator 3, and 18
Is a power supply unit, and 19 is a water flow switch.

The operation of the conventional ionized water generator 3 configured as described above will be described below. The raw water that has been passed through the raw water pipe 1 by opening the faucet 2 removes impurities such as residual chlorine odor and general sterilization in the raw water by the water purifier 4, and then passes through the flow rate sensor 6 to the electrolytic cell 7. . On the other hand, power supply unit 1
The electric power supplied from 8 is controlled to a predetermined DC voltage by the controller 17 and supplied to the electrodes 9 and 10. As a result, acidic ionized water is generated in the anode chamber 7b and alkaline ionized water is generated in the cathode chamber 7a.
When a voltage is applied so that the voltage becomes a negative voltage, alkaline ionized water is continuously obtained from the alkaline ionized water discharge passage 14 and acidic ionized water is continuously obtained from the acidic ion water discharge passage 15.

By the way, when the ion water generator 3 is operated for the purpose of generating alkaline ionized water, the structure of the channel for generating alkaline ionized water and the channel for generating acidic ionized water, and the volumes of the cathode chamber 7a and the anode chamber 7b are normally used. Since there is not much difference between the two, the same amount of acidic ionized water as alkaline ionized water is produced at the same time. Therefore, for the purpose of increasing the production amount of alkaline ionized water, the fixed flow restricting throttle portion 16 is provided in the water supply passage 13b to the anode chamber 7b shown in FIG. In general, the amount of alkaline ionized water is reduced and the amount of alkaline ionized water discharged is increased. However, if the flow restricting fixed throttle portion 16 is extremely squeezed in order to reduce the amount of acidic ionized water produced, the pH of the acidic ionized water becomes strongly acidic, and it is necessary to supply a large current. This causes a problem of consuming a large amount of electric power at the same time as shortening the life of the electrode. Since the flow rate of the acidic ionized water is kept low, the high-concentration HClO (hypochlorous acid) generated on the anode side stays in the anode chamber 7b for a long period of time, diffuses through the diaphragm 8, and the cathode chamber 7a There is a problem that the alkaline ionized water on the side mixes with and flows out. Therefore, the electrode life is extended and the power consumption is reduced, while at the same time HCl
Since it is necessary to prevent the mixture of O (hypochlorous acid) into the alkaline ionized water, the ratio of the discharged amount of the alkaline ionized water to the acidic ionized water is usually 4: 1. However, the discharge amounts of the alkaline ionized water and the acidic ionized water are easily affected by the flow rate of the raw water, and the ratio of the discharge amounts of both is greatly changed. Here, the ratio between the raw water flow rate and the discharge rate will be described. FIG. 7 is a conventional relationship diagram of the ratio of the raw water flow rate and the discharge amount. In FIG. 7, the horizontal axis represents the raw water flow rate (l / mi
n. ), And the vertical axis represents the discharge amount of alkaline ionized water (Q
The ratio Qa / Q between a) and the discharge amount (Qb) of acidic ionized water
b is shown. Raw water flows in and the flow rate is about 0.8 l / m
in. When it reaches, the flow rate sensor 16 detects it and electrolysis is started by a signal from the controller 17.
The discharge amount ratio (Qa / Qb) at that time is about 7. Here, the inflow rate of raw water is about 0.8 l / min. The reason for starting the electrolysis as described above is that below that, HClO (hypochlorous acid) mixes with the alkaline ionized water on the cathode side and flows out. Next, the inflow rate of the raw water gradually increased with the lapse of time to 4 l / min. The discharge amount (Qa) of alkaline ionized water is about 3.
2 l / min. In addition, the discharge amount (Qb) of acidic ionized water was about 0.8 l / min. Discharge rate ratio (Qa / Q
In b), a predetermined value of about 4 is obtained, and ionized water is continuously produced. Further, when the inflow amount of the raw water is increased, the discharge amount of the acidic ion water increases, and the discharge amount ratio (Qa / Qb) decreases to about 3. As described above, the conventional ion water generator 3 is provided with the fixed throttle portion 16 for adjusting the flow rate in the water supply path of the acidic ion water generation flow path to suppress the inflow amount of the raw water, thereby reducing the discharge amount of the acidic ion water and reducing the alkaline property. The amount of ionized water discharged is increased. Further, a predetermined amount or more of raw water is made to flow in advance to supply power to the electrode to prevent HClO (hypochlorous acid) generated on the anode side from mixing with alkaline ionized water on the cathode side and flowing out. .

[0006]

However, in the ion water generator of the prior art, since the fixed throttle portion for adjusting the flow rate is provided in the water supply path to the anode chamber, if the water pressure of the raw water changes, the inflow rate also changes. There is a problem. Further, in order to prevent HClO (hypochlorous acid) generated in the anode chamber side from mixing with alkaline ionized water in the cathode chamber and flowing out, a certain amount or more of raw water is preliminarily supplied and electricity is supplied to the electrode later. However, there is a problem that the raw water is discharged in vain. Furthermore, if the inflow of raw water changes, the discharge amount of alkaline ionized water (Qa)
Since the ratio Qa / Qb of the discharge amount of acidic ionized water (Qb) fluctuates, there is also a problem that the inflow rate of raw water needs to be finely controlled in order to generate a fixed amount of ionized water. Was there.

On the contrary, in the ion water generator which requires acidic ion water, there is a problem that the pH of treated water is lowered when alkaline ion water is mixed.

Therefore, the present invention solves the above-mentioned problems of the prior art, and the ratio Qa between the discharge amount (Qa) of alkaline ionized water and the discharge amount (Qb) of acidic ionized water is changed even if the inflow amount of raw water changes. / Qb is kept constant, HCIO (hypochlorous acid) is prevented from being mixed into alkaline ionized water even when the flow rate of acidic ionized water is low, and the discharge of raw water is suppressed to a small amount, which has a simple structure and is maintenance-free. It is intended to provide an ionized water generator.

Further, the present invention provides a maintenance-free ion water generator that does not mix alkaline ionized water with acidic ionized water at a low flow rate, suppresses discharge of raw water to a small amount, has a simple structure. With the goal.

[0010]

In order to achieve the above object, the ion water generator of the present invention has a variable resistance flow rate control having a characteristic that the flow path resistance is reduced in a low pressure region in a water supply path connected to an anode chamber. It is characterized by having a valve.

Further, it is desirable to further provide a resistance variable flow rate control valve having a characteristic that the flow path resistance is lowered in a low pressure region in the discharge path connected to the cathode chamber.

Furthermore, a variable resistance flow control valve has a throttle plate having a water flow hole at its center, and a movable plate with a flow passage arranged below the throttle plate to change the gap between the throttle plate and the water pressure of the raw water supplied. It is preferable to provide a stopper ring for setting the lower limit position of the movable plate with a flow path.

Further, the movable plate with the flow path is made of an elastic material. Further, the water supply passage connected to the cathode chamber is provided with a resistance variable flow rate control valve having a characteristic that the flow passage resistance decreases in a low pressure region.

[0014]

Since the ion water generator of the present invention is provided with the variable resistance flow control valve having the characteristic that the flow path resistance decreases in the low pressure region in the water supply passage connected to the anode chamber, the inflow of raw water is small. Even so, a required amount of raw water can be made to flow into the acidic ionized water generation flow path, and HCIO can be prevented from diffusing into the cathode chamber.

Further, since the resistance variable flow rate control valve having the characteristic that the flow path resistance is lowered in the low pressure region is provided in the discharge passage connected to the cathode chamber, the alkaline ionized water is prevented from diffusing HCIO into the cathode chamber. The discharge amount can be controlled to be constant.

Further, the variable resistance flow rate control valve has a throttle plate having a water flow hole in the center thereof, and a movable plate with a flow passage arranged below the throttle plate to change the gap between the throttle plate and the water pressure of the raw water supplied. Since the stopper ring for setting the lower limit position of the movable plate with the flow path is provided, it is possible to reduce the throttle characteristic in the low water pressure range and increase the throttle characteristic in the high water pressure range.

Further, since the movable plate with the flow path is made of an elastic material, it can be easily brought into pressure contact with the throttle plate by the water pressure of the raw water, and the throttle characteristic can be varied to adjust the flow rate.

Furthermore, since the variable resistance flow control valve having the characteristic that the flow path resistance is lowered in the low pressure region is provided in the water supply passage connected to the cathode chamber, the alkaline ionized water does not diffuse into the anode chamber and the acid flow is prevented. The discharge amount of ionized water can be controlled to be constant.

Embodiments of the present invention will be described in detail below with reference to the drawings. Here, the case of producing alkaline ionized water will be described. FIG. 1 is a schematic overall view of an ionized water generator according to an embodiment of the present invention. FIG. 2A is a sectional view of a variable resistance flow rate control valve of an ion water generator according to an embodiment of the present invention, and FIG. 2B is a variable resistance flow rate control of an ion water generator according to an embodiment of the present invention. It is sectional drawing at the time of operation of a valve. FIG. 2C is an exploded front view of the variable resistance flow control valve of the ion water generator according to the embodiment of the present invention.

Water discharge path, 17 is a controller, 18 is a power supply unit, 1
9 is a water flow switch. The same reference numerals as those of the conventional example have the same basic operations and functions, and thus the description thereof will be omitted. Reference numeral 20 is a variable resistance flow rate control valve provided in the raw water supply path 13b to the anode chamber 7b, and 21 is a variable resistance flow rate control valve provided in the alkaline ionized water discharge path 14. The resistance variable flow rate control valves 20 and 21 have the same structure, which is shown in FIGS. 2 (a), 2 (b), and 2 (c). Here, FIG. 2A shows a state when the raw water inflow is started, and FIG. 2B shows a state when the raw water pressure rises.
Providing the resistance variable flow rate control valve 20 is usually sufficient, but providing the resistance variable flow rate control valve 21 further makes the flow rate control more effective. Reference numeral 30 is a diaphragm plate, 31 is a movable plate with a flow path, 32 is a stopper ring, and 33 is a case for housing them. A disc-shaped diaphragm plate 30 having a water flow hole 30a in the center is fixed by providing a step on the inner wall of the case 33. Next, the movable plate 31 with flow passages having the flow passages 31b at its four corners and the adjustment hole 31a provided in the center is placed immediately below the diaphragm plate 30, and the stopper ring 32 is used to set the movable range of the movable plate 31 with flow passages. Set the lower limit position. It is important that this lower limit position is a position such that when the movable plate 31 with a flow path moves up and down in accordance with the water pressure of the raw water, an interval for allowing the maximum flow rate is formed between the movable plate 31 and the throttle plate 30. Is. Initially, due to gravity, the movable plate 31 with the flow channel is the stopper ring 32.
Although it is on the upper side, when the raw water flows in from the direction of the arrow, the water pressure is low in the initial stage, so that the raw water flows through the adjusting hole 31a and the passage 31b of the movable plate 31 with the flow passage to the flow control valve. Discharge from. Next, when the flow rate increases and the water pressure of the raw water rises, as shown in FIG. 2B, the flowable movable plate 31 is pressed against the diaphragm plate 30 by water pressure. Therefore, the raw water is discharged only from the adjusting hole 31a of the movable plate 31 with the flow path. That is, the flow path resistance increases. When the water pressure of the raw water becomes low in this state, the state returns to the state shown in FIG. 2A and the discharge can be continued from the flow rate control valve. In this way, the resistance variable flow rate control valve 20 is capable of reducing the flow rate resistance and increasing the discharge amount in a low pressure region where the raw water pressure is low, and increasing the flow rate resistance and suppressing the discharge amount when the water pressure increases. , 21 can be obtained. In order to effectively control the flow rate, it is preferable that the movable plate 31 with the flow path is made of an elastic material such as rubber or plastic that is easily deformed by compression by water pressure.

Next, FIG. 3 (a) is a sectional view of a variable resistance flow control valve of an ion water generator according to another embodiment of the present invention, and FIG. 3 (b) is an ion according to another embodiment of the present invention. FIG. 3 is a sectional view of the variable resistance flow rate control valve of the water generator during operation.
(C) is an exploded front view of the variable resistance flow control valve of the ionized water generator in one Example of this invention. The same reference numerals as those in the above-described embodiment have the same basic operation and function, and thus the description thereof will be omitted. Here, FIG. 3A shows a state at the time of starting raw water inflow, and FIG. 3B shows a state when the raw water pressure rises. Reference numeral 31c is a projection-like flow rate adjusting projection provided in the center of the movable plate 31 with a flow path. Although the raw water flows in from the direction of the arrow, since the water pressure is low in the initial stage, the raw water has a large number of control holes 31a provided in the movable plate with flow path 31 and the movable plate with flow path 3
Discharge from the flow rate control valve via the outer peripheral portion of 1. Next, when the flow rate increases and the water pressure of the raw water rises, as shown in FIG. 3B, the movable plate 31 with the flow path is brought into pressure contact with the diaphragm plate 30 by the water pressure, and the flow rate adjusting projection 31 is formed in the water flow hole 30a.
c is inserted to narrow the water flow hole 30a. For this reason, only the adjustment hole 31a of the movable plate 31 with a flow path is passed through, and the flow path hole 30a further reduces the flow path area for discharge. In order to adjust the pressure contact time of the movable plate 31 with flow passages, it is also preferable to urge the movable plate 31 with flow passages downward in advance by a spring or the like. In this state, when the water pressure of the raw water becomes low, the state returns to the state shown in FIG. 3B, and the variable flow rate control valves 20 and 21 can be obtained by continuing the discharge from the flow rate control valve. The variable resistance flow rate control valve 2 described above
FIG. 4 shows the flow rate of raw water discharged from the resistance variable flow rate control valves 20 and 21 by changing the water pressure of the raw water flowing into 0 and 21 and comparing with the conventional example. FIG. 4 is a relationship diagram of the raw water pressure and the treated water discharge amount in one embodiment of the present invention. In FIG. 4, the horizontal axis represents the raw water pressure (Mpa), and the vertical axis represents the treated water discharge rate (l / mi).
n. ). This conventional example is an example in which the fixed throttle portion 16 for flow rate adjustment is used, and the present example is shown in FIGS. 2 (a), 2 (b) and 2 (c). This is the case where the variable resistance flow rate control valves 20 and 21 are used. In both cases, the discharge amount of treated water is 0.8 when the raw water pressure is 0.1 MPa.
l / min. Is adjusted so that In the conventional example, the discharge amount of treated water is finally 0.
2 l / min. It can be seen that the treated water is discharged even at a small raw water pressure of about 0.02 MPa as compared with the treated water discharged at a certain level. When the raw water pressure further increases, the treated water discharge amount of the conventional example continues to increase, but in this embodiment, the treated water discharge amount is maintained substantially constant when the raw water pressure is 0.1 Mpa or more. From this, the effect of the resistance variable flow rate control valves 20 and 21 which can control the discharge amount of treated water by decreasing the flow passage resistance in the low pressure region and increasing the discharge amount of treated water in the high pressure region is clear. Is.

Next, the variable resistance flow control valve of this embodiment used in FIG. 4 is provided in the ion water generator 3 of FIG.
And a variable resistance flow control valve having only 20 were prepared to generate ionized water. FIG. 5 shows the relationship of the ratio Qa / Qb between the discharge amount (Qa) of alkaline ionized water and the discharge amount (Qb) of acidic ionized water when the flow rate of raw water is changed. FIG. 5 is a relationship diagram between the raw water flow rate and Qa / Qb in one embodiment of the present invention. In FIG. 5, the horizontal axis represents the raw water flow rate (l / min.) And the vertical axis represents the ratio Qa / Qb between the discharge amount (Qa) of alkaline ionized water and the discharge amount (Qb) of acidic ionized water. The conventional example is the same as in FIG. 4 and is an example in which a fixed throttle portion 16 for flow rate adjustment is used, and A is a water supply channel 1 connected to the anode chamber 7b of the ion water generator 3 in FIG.
In the case where the variable resistance flow rate control valve is provided only on 3b, and 20 is provided, B indicates the water supply passage 13b connected to the anode chamber 7b of the ion water generator 3 of FIG. 1 and the alkaline ionized water discharge passage 14 connected to the cathode chamber 7a. 20 with a variable resistance flow control valve
The case is 21. In the conventional example, the raw water flow rate is 0.8 l
/ Min. Qa / Qb becomes 7, and Qa / Qb gradually decreases as the raw water flow rate increases. That is, in the initial stage of inflow of raw water, the discharge amount of alkaline ionized water is much larger than the discharge amount of acidic ionized water. However, the raw water flow rates of both A and B according to the method of the present invention are 0.3 l / min. Therefore, Qa / Qb has already become 2, and a discharge amount of acidic ion water sufficient to prevent HClO generated in the anode chamber 7b from diffusing through the diaphragm 8 into the cathode chamber 7a is obtained. As a result, the raw water flow rate was 0.3 l / min. The electrolysis can be started with a small amount of raw water flow. As a result, the ion water generator 3
It is possible to reduce the amount of raw water flow to be wastefully discarded in the initial stage of the operation of, and it is possible to sufficiently eliminate the inclusion of HClO.
Furthermore, the raw water flow rate is 1 l / min. To 10 l / min.
Qa / Qb is constant with almost no change even when the value is increased to. This means that it is possible to always obtain alkaline ionized water and acidic ionized water with a constant discharge amount ratio without being affected by fluctuations in the raw water flow rate.

By the way, in the ionized water generator which requires acidic ionized water, the anode chamber and the cathode chamber are opposite to those in the above-described embodiment. In this case, a variable resistance flow control valve may be provided in the water supply passage connected to the cathode chamber and, if necessary, the discharge passage connected to the anode chamber. By using the variable resistance flow rate control valve in the water supply path connected to the cathode chamber in this way, the alkaline ionized water is diffused into the acidic ionized water and p
Lowering H can be prevented.

Therefore, when the variable resistance flow rate control valve of the present embodiment is provided, it has a simple structure that does not require fine adjustment of the raw water flow rate as in the conventional example and does not require an adjusting mechanism therefor, and is a maintenance-free ion. A water generator can be obtained. This is more effective when producing a large amount of ionized water for industrial use.

[0024]

As is apparent from the above, according to the present invention, the feed water passage connected to the anode chamber is provided with the variable resistance flow control valve having the characteristic that the flow passage resistance decreases in the low pressure region. The required amount of raw water can be made to flow into the acidic ionized water generation flow path even if the inflow amount of H is reduced, and H
It is possible to prevent the CIO from diffusing and to generate a constant flow of ionized water without being affected by the fluctuation of the raw water flow rate.

Further, since the variable resistance flow rate control valve having the characteristic of decreasing the flow path resistance in the low pressure region is provided in the discharge passage connected to the cathode chamber, the required discharge amount of acidic ionized water is small even if the raw water flow rate is small. Therefore, safe alkaline ionized water can be obtained without HCIO diffusion into the cathode chamber.

Further, the variable resistance flow rate control valve has a throttle plate having a water flow hole in the center thereof, and a movable plate with a flow passage arranged below the throttle plate to change the gap between the throttle plate and the water pressure of the raw water supplied. Since it is equipped with a stopper ring that sets the lower limit position of the movable plate with flow path, the flow rate can be adjusted by automatically varying the resistance in the low water pressure range and high water pressure range, and a maintenance-free ion water generator Can be provided.

Further, since the movable plate with the flow path is made of an elastic material, it can be easily brought into pressure contact with the throttle plate by the water pressure of the raw water, and the flow rate can be adjusted with a simple structure.

Further, since the resistance variable flow rate control valve having the characteristic that the flow passage resistance is lowered in the low pressure region is provided in the water supply passage connected to the cathode chamber, the alkaline ionized water does not diffuse into the acidic ionized water, It is possible to provide an ionized water generator capable of stabilizing the pH of acidic ionized water and controlling the discharge amount to be constant.
