Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolytic ion water generator.

[0002]

2. Description of the Related Art Conventionally, an ionized water generator divides the center of a pair of electrodes with a non-woven fabric, a unglazed plate or the like with a partition that partially limits the passage of water, and applies a voltage to both electrodes to prevent the passage of water. The ions are allowed to pass through the diaphragm by the action of an electric field while being restricted, and are attracted to the respective electrodes to be electrolyzed into acidic ion water and alkaline ion water.

[0003]

However, the problem of the ion water generator using the above-mentioned diaphragm is that there is a risk of bacteria and microorganisms adhering and growing on the diaphragm, and further, the diaphragm is made of an insulating material due to long-term use. This causes clogging, interrupts the flow of current, and lowers the electrolysis efficiency.

That is, bacteria, such as Escherichia coli, tend to inhabit the membrane wet with water, and the membrane is attracted to the electrode by cations toward the cathode side and anions toward the anode side. Although they pass through, these ions are not limited to hydroxyl ions and hydrogen ions, but also include calcium ions, magnesium ions, and silicon content contained in water, which is itself an insulator and calcium. This is because the ions and magnesium ions adhere to the diaphragm and are deposited as insoluble and insulating substances such as magnesium carbonate ions and magnesium carbonate ions.

Therefore, the present invention has been made in order to solve the above-mentioned problems, and it is an ionized water that can guarantee efficient electrolysis over a long period of time by omitting the diaphragm and having no breeding source of bacteria and microorganisms. It is intended to provide a generator.

[0006]

In order to solve the above-mentioned problems, in order to solve the above-mentioned problems, the constitution of the present invention, which is based on the above-mentioned claims, is based on the above-mentioned object. It is configured as a thin vertical two-divided container with the portion 1b, the tap water inlet 2 is provided at one end side of the electrolytic cell 1, and the acidic ion water outlet 3 and the alkaline ion water outlet 4 are provided at the other end side, and the electrolysis is performed. A slit-shaped narrowed channel 10 having a cross-sectional area smaller than the cross-sectional area of the tap water inlet 2 is formed in the electrolytic cell 1 at a portion downstream of the portion where the tap water inlet 2 is communicated in the tank 1 over the entire width of the electrolytic cell 1. A weir 5 to be formed is provided, and a tank chamber 6 of a predetermined capacity having a width equal to that of the slit-shaped constriction flow channel 10 is provided upstream of the weir 5, and the electrolytic cell 1 is also provided.
An electrolytic cell chamber 7 is provided inside the slit-shaped constricting channel 10 in the inside, and a pair of flat plate-shaped anode electrode plates 8 and cathode electrode plates 9 are provided in the electrolytic cell chamber 7, and the center of the electrode plate 8 An electrolytic flow path 7a communicating with the tank chamber 6 via the slit-shaped constriction flow path 10 is formed and accommodated in parallel, and the upstream end of the acidic ion water outlet 3 is located at the downstream side of the electrolytic flow path 7a. Board 8
On the other hand, the technical means for connecting the upstream end of the alkaline ionized water outlet 4 to the cathode electrode plate 9 side on the downstream side of the electrolytic flow path 7a is taken.

[0007]

Therefore, in the ion water generator of the present invention, the water flowing from the tap water inlet 2 first flows into the tank chamber 6,
After passing through the slit-shaped constriction flow channel 10, it flows into the electrolytic flow channel 7a. Since the cross-sectional area of the slit-shaped constriction channel 10 is set smaller than the cross-sectional area of the tap water inflow port 2, water has a resistance to pass through the slit-shaped constriction channel 10, and therefore, The water that has flowed into the tank chamber 6 is first pressed into the tank chamber 6 and spreads over the entire width of the tank chamber 6. Then, when passing through the slit-shaped narrowed channel 10, the water flow becomes a thin and almost full-width flow that matches the cross-sectional shape of the slit-shaped narrowed channel 10, and becomes a laminar flow referred to in fluidics and flows into the electrolytic flow channel 7a. To do.

Since the laminar flow has a tendency not to change the flow direction unless the flow path is bent or there is an obstacle in the middle, the water in the electrolytic flow path 7a on the side of the anode electrode plate 8 is the surface of the anode electrode plate 8. Along the surface of the cathode electrode plate 9 on the cathode electrode plate 9 side, and the water and the cathode electrode plate 9 on the anode electrode plate 8 side.
The water on the side has the effect of flowing without mixing, without the use of conventional diaphragms.

A direct current voltage of a predetermined voltage is applied between the anode electrode plate 8 and the cathode electrode plate 9, and the water flowing in the electrolysis passage 7a between them is electrolyzed while passing through the electric field. It is the same operation as before.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes an electrolytic cell, and the electrolytic cell 1 is configured in a thin vertical two-divided container shape with a one side container portion 1a and another side container portion 1b. It is needless to say that both the one-side container part 1a and the other-side container part 1b are made of a waterproof material such as a synthetic resin, but preferably they are insulated to accommodate the later-described anode electrode plate 8 and cathode electrode plate 9. It is desirable to use a material. Further, the one-side container part 1a and the other-side container part 1b are hermetically sealed by inserting packing 11 into a fitting part and fixing each other with fastening screws 12, 12, 12 ... It is in a state.

A tap water inlet 2 is provided at one end of the electrolytic cell 1, and an acidic ion water outlet 3 and an alkaline ion water outlet 4 are provided at the other end. That is, in the electric field tank 1, the tap water flowing from the tap water inlet 2 flows through the electric field tank 1 and flows out from the acidic ion water outlet 3 and the alkaline ion water outlet 4.

In addition, a cross-sectional area smaller than the cross-sectional area of the tap water inlet 2 is provided in a portion of the electrolysis tank 1 downstream of the portion where the tap water inlet 2 communicates with the electrolysis tank 1 over substantially the entire width thereof. Weir 5 forming slit-shaped constriction channel 10
A tank chamber 6 having a predetermined width and a width equal to that of the slit-shaped narrowed channel 10 is provided upstream of the weir 5. In the present application, the width and width of the electrolytic cell 1 are the inner dimensions in the left-right direction of FIG. 1 and FIG.
The widths of the slit-shaped narrowed channel 10 and the tank chamber 6 both have dimensions of substantially the entire width of the electrolytic cell 1.

The slit gap (width in the left-right direction in FIG. 3) of the slit-shaped constriction channel 10 is determined from the cross-sectional area of the tap water inlet 2 (cross-sectional area of the inner diameter). Set to be smaller. In the illustrated embodiment, a pre-stage weir 5a is provided also in the upstream portion of the weir 5, and a pre-stage tank chamber 6a is further provided in the upstream part of the weir 5, so that water is supplied to the weir 5 and the pre-stage weir 5.
Although it is configured so as to pass through two stages of a and a, the front weir 5a and the front tank chamber 6a may be omitted. Further, as shown most clearly in "FIG. 2", the weir 5 is provided with rectifying protrusions 13, 13, 13 ... In the vertical direction, but the rectifying protrusions 13, 13, 13 ... Are also omitted. It is possible.

An electrolytic cell chamber 7 is provided in the electrolytic cell 1 at a downstream side of the slit-shaped narrowed channel 10, and a pair of flat plate-shaped anode electrode plates 8 and cathode electrodes are provided in the electrolytic cell chamber 7. The plate 9 and the plate 9 are housed in parallel with each other by forming an electrolytic flow path 7a in the center of the plate 9 which communicates with the tank chamber 6 through the slit-shaped narrowed flow path 10.

There are no particular restrictions on the materials of the anode electrode plate 8 and the cathode electrode plate 9, but it is a matter of course that a corrosion resistant metal is used, and between the anode electrode plate 8 and the cathode electrode plate 9, there is no restriction. As in the prior art, a predetermined DC voltage is applied by the power supply device as shown in FIG.

In the power supply device shown in FIG. 5, 31 is a transformer, 32 is a rectifier, 33 is a stable circuit, 34 is a water pressure switch, and 35 is an applied voltage changeover switch, which are connected as shown.

As shown in FIG. 4, the water pressure switch 35 is used such that the power supply circuit is closed when water pressure is applied to the inside of the flow path. In the example of FIG. 4, the tap water inlet 2 is upstream. A reduced diameter portion 41 is provided in the middle of the conduit body 40 to be interposed in a proper position such as a portion, and a piston 42 that can be inserted and removed is inserted from a cylinder 42 at a position upstream of the reduced diameter portion 41 of the conduit body 40. The water pressure switch 34 composed of a micro switch is opened and closed by the movement of 42. In FIG. 4, 43 is a packing, 44 is a retaining ring for the packing 43, and 44 is a packing. Further, although the spring is not shown in the drawing, when there is no water pressure, the piston 42 is lowered by the spring with a built-in micro switch and the water pressure switch 35 is in the open state (OF
(F state).

In the above power supply device, a voltage is applied so that the left side is the anode electrode plate 8 and the right side is the cathode electrode plate 9, and when the applied voltage changeover switch 35 is operated, the cathode side and the anode side are connected. Is applied in reverse. It should be noted that this reverse application is for reversely energizing to wash off the surface of the electrode, as is conventionally done, to release the deposits and deposits.

Further, the slit-shaped narrowing channel 10 and the electrolytic channel 7a between the anode electrode plate 8 and the cathode electrode plate 9 are
It is more practical that they have substantially the same dimensions and that they are on substantially the same plane because turbulence does not easily occur in the water flow.

The upstream end of the acidic ion water outlet 3 is located downstream of the electrolytic flow passage 7a on the anode electrode plate 8 side, and the upstream end of the alkaline ion water outlet 4 is also located downstream of the electrolytic flow passage 7a on the cathode electrode side. It communicates with the plate 9 side.

That is, the acid ion water outlet 3 has its upstream end located on the anode electrode plate 8 side on the downstream side of the electrolytic flow path 7a, so that the acidic ion water outlet port 3 flows along the surface of the anode electrode plate 8 and the acid ion water is hydrolyzed by electrolysis. The alkaline ionized water outlet 4 is arranged so that the upstream end of the alkaline ionized water outlet 4 flows along the surface of the cathode electrode plate 9 at the downstream side of the electrolytic flow path 7a and the alkaline ionized water is discharged by electrolysis.

The acidic ion water outlet 3 and the alkaline ion water outlet 4 have a cross-sectional area which is half the cross-sectional area of the electrolytic flow path 7a formed by the gap between the anode electrode plate 8 and the cathode electrode plate 9. If it is set to 1 or more, turbulent flow is hardly generated in the upstream portion, but in the illustrated example, it corresponds to the downstream side of the electrolytic flow passage 7a and approximately half of the electrolytic flow passage 7a on the anode electrode plate 8 side. The collision plate 14 is provided, and the water flowing along the surface of the anode electrode plate 8 collides with the collision plate 14, and the folding gap 18 formed between the downstream end of the anode electrode plate 8 and the collision plate 14 is formed. To the return flow path 15, and the acidic ion water outlet 3 is provided at the downstream end of the return flow path 15. The folded flow path 15 is formed in the bulging portion 16 (see FIG. 1) bulging in the one-side container portion 1a and is located along the back surface of the anode electrode plate 8.

Therefore, in the illustrated embodiment, the influence of the turbulent flow that may occur at the upstream portion of the acidic ion water outlet 3 is set so that the position of the acidic ion water outlet 3 is located farther from the downstream end of the anode electrode plate 8. I am avoiding it.

Further, in the illustrated example, the water flowing along the surface of the cathode electrode plate 9 should go straight through the upper gap 19 formed between the collision plate 14 and the other side container portion 1b. However, a downstream side tank chamber 17 having a predetermined capacity that communicates with the electrolytic flow path 7a through the upper gap 19 is provided on the downstream side of the electrolytic flow path 7a, and the upstream end of the alkali ion water outlet 4 is provided. Communicates with this downstream side tank chamber 17.

That is, the downstream side tank chamber 17 is interposed between the alkaline ionized water outlet 4 and the electrolytic flow passage 7a, and has a predetermined capacity to make the local pressure fluctuation uniform. Therefore, in the illustrated embodiment, the influence of the turbulent flow that may occur at the upstream portion of the alkaline ionized water outlet 4 is avoided by the pressure fluctuation equalizing action of the downstream side tank chamber 17.

As described above, the folded-back flow passage 15 and the downstream side tank chamber 17 are not always necessary, but when the area of the anode electrode plate 8 and the cathode electrode plate 9 is reduced, the size is reduced. Has a remarkable turbulent flow prevention effect. In the illustrated example, one of the anode electrode plate 8 side and the cathode electrode plate 9 side is the return passage 15 and the other is the downstream tank chamber 17, but both return passages 15 or the downstream tank chamber 17 are used. Of course, there is nothing wrong with it.

In the figure, 21 is a screw hole for fastening the electric field tank,
Reference numeral 22 is a screw hole for fixing the electrode plate, and 23 is a lead wire extraction hole for the electrode.

EFFECTS OF THE INVENTION The present invention is as described above, and since the diaphragm which has been indispensable in the past is not used, bacteria and microorganisms do not adhere to the diaphragm, and the possibility of clogging of the diaphragm is of course eliminated. That is, it is possible to provide an ion water generator that can be stably used for a long period of time.

In the present invention, the diaphragm is omitted, but the weir 5 and the tank chamber 6 are provided, so that the water passing through the electrode gap becomes a clean laminar flow, and the alkaline ionized water and the acidic ionized water to be electrolyzed are separated. Not only does it not mix, the electrolysis efficiency does not decrease, but rather the diaphragm does not act as a kind of insulating material, so the electrolysis efficiency increases and it is possible to provide an efficient ion water generator. .
