Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an improvement of an ionized water generator.

0002

[Conventional technology]

Conventionally, ionized water generators pass water through a material such as non-woven fabric or unglazed plate through the center of opposing electrodes. The passage of water is restricted by partitioning it with a diaphragm that partially restricts the water and applying voltage to both electrodes. The ions are then passed through the diaphragm by the action of an electric field and attracted to each electrode, producing acidic ions. It is designed to electrolyze water and alkaline ionized water.

0003

[Problem that the idea aims to solve]

However, the problem with ionized water generators using the above-mentioned diaphragm is that bacteria and microorganisms are present in the diaphragm. There is a risk that the diaphragm may adhere and grow, and furthermore, the diaphragm may become damaged by the insulator after long-term use. This causes clogging, which cuts off the flow of current and reduces electrolytic efficiency.

0004 In other words, bacteria such as E. coli can easily live in the diaphragm that gets wet with water, and the above-mentioned The diaphragm is attracted to the electrode, with cations flowing towards the cathode and anions towards the anode. will pass through, but these ions are limited to hydroxyl ions and hydrogen ions. Calcium ions, magnesium ions, and silicon content contained in water. The silicon content is itself an insulator, and calcium ions and magnesium The bulk ions adhere to the diaphragm and are absorbed by insoluble calcium carbonate and calcium carbonate. This is because it becomes an insulating substance and is deposited.

[0005] Therefore, this invention was devised to solve the above problem, and the diaphragm was omitted. An ionizer that does not contain any breeding sources for bacteria or microorganisms and can guarantee efficient electrolysis over a long period of time. The purpose of this project is to provide a water generator for water production.

[0006]

[Means to solve the problem] In line with the above purpose, the structure of the present invention, which has the gist of the above-mentioned utility model registration claims, is as follows: In order to solve the above-mentioned problem, an electrolytic cell 1 with a raw water inlet 2 at one end is installed. A pair of flat electrodes 8 and 9 are housed in parallel with an electrolytic flow path 7a formed in the center. At the other end of the tank 1, there is an acidic ion which communicates with the anode plate-like electrode 8 side of the electrolytic flow path 7a. The alkali ions that communicate with the water outlet 3 and the cathode flat plate electrode 9 side of the electrolytic flow path 7a A water outlet 4 is provided, and the acidic ionized water outlet 3 and the alkaline ionized water outlet 4 are provided. One or both of the above include the amount of outflow from the acidic ionized water outlet 3 and the amount of alkaline water. Flow restrictors 51 and 52 are provided to provide a difference in the amount of outflow from the ionized water outlet 4. This was achieved by taking technical measures.

[0007]

[Effect]

Therefore, in the present invention, the water passing through the electrolytic flow path 7a is connected to the anode flat electrode 8 and the cathode flat electrode 8. It is electrolyzed by the electric field generated between the electrode 9 and acidic ions on the anode flat electrode 8 side. The alkaline ionized water gathers on the cathode flat plate electrode 9 side, and the acidic ionized water exits. Acidic ionized water flows out from 3 and alkaline ionized water flows out from alkaline ionized water outlet 4. This is the same as before.

[0008] However, in the present invention, the diaphragm that was conventionally required for the electric field action described above is not used. I haven't. The function of this diaphragm is to prevent water from mixing due to turbulence, and to prevent water from mixing due to turbulence. One side and the other side partitioned by each have a uniform pH value. However, this does not necessarily mean that electrolysis cannot occur without this diaphragm. That is also true.

[0009] Mixing due to turbulence causes the pH values of acidic ionized water and alkaline ionized water to be close to each other. As a result, the electrolytic efficiency decreases, but the inventor of the present invention We focused on the fact that it is not impossible to adjust the pH value if a certain amount of control is applied. sand In other words, if the purpose is to obtain alkaline ionized water, alkaline ionized water is on the acidic ionized side. Conversely, when the purpose is to obtain acidic ionized water, acidic ionized water becomes alkalized. By allowing it to mix into the potassium ionized water side, ionized water with the desired pH value can be obtained. Therefore, this control is performed by the acidic ionized water outlet 3 and the alkaline ionized water outlet 4. This can be achieved by creating a difference in the amount of outflow. That is, the flow restricting bodies 51 and 52 are It has the effect of controlling the outflow amount of electrolyzed water and biasing the mixing of electrolyzed water in a predetermined direction.

【Example】

Next, embodiments of the present invention will be described with reference to the accompanying drawings. In the figure, 1 is an electrolytic cell, and this electrolytic cell 1 has a raw water inlet 2 at one end. 1, a pair of flat electrodes 8 and 9 are housed in parallel with an electrolytic flow path 7a formed in the center. The other end of the electrolytic cell 1 is connected to the anode flat electrode 8 side of the electrolytic flow path 7a. The acidic ionized water outlet 3 connected to the cathode flat plate electrode 9 side of the electrolytic flow path 7a This is a version that omits the diaphragm compared to the conventional version that has a potassium ion water outlet 4. However, in this example, in order to avoid the occurrence of turbulence as much as possible, "Fig. 2" to "Fig. 4" I am using something like the one shown below.

[0011] That is, the electrolytic cell 1 has a thin longitudinal structure with one side container part 1a and the other side container part 1b. It is constructed in the shape of a two-part container. The one side container portion 1a and the other side container portion 1b are the same. Of course, it is made of a waterproof material such as synthetic resin, but it is preferable to use an anode flat plate as described below. In order to accommodate the shaped electrode 8 and the cathode flat electrode 9, it is preferable to use an insulating material. . Moreover, the one side container part 1a and the other side container part 1b have a packing 11 in the fitting part. Thin, airtight seals that are secured to each other with interposed fastening screws 12, 12, 12... It is shaped like a container.

0012 Then, a raw water inlet 2 is provided at one end of the electrolytic cell 1, and an acidic ion water flow is provided at the other end. An outlet 3 and an alkaline ionized water outlet 4 are provided. That is, this electric field chamber 1 is Raw water such as tap water that flows in from the raw water inlet 2 passes through the electric field tank 1 and collects acidic ions. The ionized water flows out from an ionized water outlet 3 and an alkaline ionized water outlet 4.

[0013] In addition, there is a portion downstream of the portion where the raw water inlet 2 in the electrolytic cell 1 is communicated with. , with a cross-sectional area smaller than the cross-sectional area of the raw water inlet 2 over the entire width of the electrolytic cell 1. A weir 5 forming a slit-like constricted flow path 10 is provided, and the slit is located upstream of the weir 5. A tank chamber 6 having a predetermined capacity and having the same width as the narrowed channel 10 is provided. main application The total width of electrolytic cell 1 is the inner dimension in the left and right direction in "Figure 2" and "Figure 3". Therefore, the width of the slit-like constricted flow path 10 and the tank chamber 6 (also shown in "Fig. 2" and "Fig. 3") are both of the electrolytic cell 1 (more precisely, the electrolytic flow path 7a described later). It will have a full width dimension.

[0014] The slit gap (width in the left-right direction in "Fig. 4") of the slit-like constricted flow path 10 is , the cross section of the slit-like constricted channel 10 is determined from the cross-sectional area (cross-sectional area of the inner diameter) of the raw water inlet 2. Set so that the area is small. This difference in cross-sectional area is due to the slit-like constriction channel 1 By narrowing the flow path with 0, the inflowing raw material water is forced into the entire tank chamber 6. , and then passes through the slit-like constricted flow path 10 to obtain a laminar flow without turbulence. I am doing it.

[0015] In the illustrated embodiment, there is also a pre-stage weir 5a in the upstream part of the weir 5, and further upstream of the weir 5a. A pre-stage tank chamber 6a is provided in the section so that water passes through two stages: the weir 5 and the pre-stage weir 5a. However, the front weir 5a and the front tank chamber 6a may be omitted. Also, As most clearly shown in FIG. , 13... are provided, but these rectifying protrusions 13, 13, 13... can also be omitted. It is.

[0016] Further, in the electrolytic cell 1, an electrolytic cell is provided on the downstream side of the slit-like constricted flow path 10. A chamber 7 is provided in which a pair of flat anode electrodes 8 and a flat cathode electrode 8 are installed. The electrode 9 is connected to the tank chamber 6 through the slit-like constricted channel 10 at its center. The electrolytic channels 7a are formed and are housed parallel to each other.

[0017] There are no particular restrictions on the materials of the anode flat electrode 8 and cathode flat electrode 9. However, it goes without saying that a corrosion-resistant metal is used, and the anode flat electrode 8 and the cathode flat electrode 8 are connected to each other. A predetermined DC voltage is applied between the electrode 9 by a power supply device (not shown). It's the same as before.

[0018] Further, the slit-like constricted flow path 10, the anode flat plate electrode 8 and the cathode flat plate electrode 9 are also included. The electrolytic flow path 7a between the It is more practical because it is less likely to cause turbulence in the flow.

[0019] Then, the upstream end of the acidic ionized water outlet 3 is connected to the anode level on the downstream side of the electrolytic flow path 7a. Place the upstream end of the alkaline ionized water outlet 4 on the plate electrode 8 side under the electrolytic flow path 7a. The flow side communicates with the cathode flat electrode 9 side.

[0020] That is, the acidic ion water outlet 3 has its upstream end connected to the anode on the downstream side of the electrolytic flow path 7a. By being located on the flat electrode 8 side, the anode flows along the surface of the flat electrode 8 and causes electrolysis. More acidic ionized water flows out, and the alkaline ionized water outlet 4 connects the upstream end to Alkaline flows along the surface of the cathode flat plate electrode 9 on the downstream side of the electrolytic flow path 7a and is electrolyzed. It allows ionized water to flow out.

[0021] The acidic ionized water outlet 3 and alkaline ionized water outlet 4 have their cross-sectional areas as an anode. Cross section of the electrolytic flow path 7a formed by the gap between the flat plate electrode 8 and the cathode flat electrode 9 If the value is set to 1/2 or more of the product, turbulence will hardly occur in the upstream region. However, in the illustrated example, an anode flat electrode of the electrolytic flow path 7a is provided on the downstream side of the electrolytic flow path 7a. A collision plate 14 corresponding to approximately half of the pole 8 side is provided to allow the flow to flow along the surface of the anode flat electrode 8. The falling water collides with this collision plate 14, and the downstream end of the anode flat electrode 8 and the collision plate 14 and flows into the folded passage 15 through the folded gap 18 formed between the folded An acidic ion water outlet 3 is provided at the downstream end of the flow path 15. Note that this turning flow The channel 15 is formed in a bulge 16 (see FIG. 1) that bulges in the one side container portion 1a. It is located along the back surface of the extremely flat electrode 8.

[0022] Therefore, in the illustrated embodiment, the risk generated at the upstream portion of the acidic ionized water outlet 3 is To reduce the influence of turbulent flow, the acidic ion water outlet 3 is positioned below the anode flat electrode 8. This is avoided by keeping a distance from the flow end.

[0023] Furthermore, in the illustrated example, the water flowing along the surface of the cathode flat electrode 9 remains as it is. However, it passes directly through the upper gap 19 formed between the collision plate 14 and the other side container part 1b. However, the electrolytic flow flows through the upper gap 19 on the downstream side of the electrolytic flow path 7a. A downstream tank chamber 17 having a predetermined capacity communicating with the passage 7a is provided, and the alkali The upstream end of the ionized water outlet 4 communicates with this downstream tank chamber 17.

[0024] That is, the downstream tank chamber 17 is connected to the alkaline ionized water outlet 4 and the electrolytic flow path. 7a, and has a predetermined capacity to prevent local pressure fluctuations. Therefore, in the illustrated example, the alkaline ionized water effluent can be homogenized. The influence of turbulence that may occur upstream of the port 4 is reduced by reducing the pressure in the downstream tank chamber 17. This is avoided by equalizing force fluctuations.

[0025] In addition, the present invention provides a connection between the acidic ionized water outlet 3 and the alkaline ionized water outlet 4. One or both of them contain the amount of outflow from the acidic ionized water outlet 3 and the amount of alkaline water. Flow restrictors 51 and 52 are provided to provide a difference in the amount of outflow from the on-water outlet 4. .

[0026] The flow rate restricting bodies 51 and 52 may be fixed or variable restrictors, and may be either fixed or variable restrictors. ", fixed throttle valves 51a, 52a, orifices 51b, 52b, variable throttle valve 51 c, 52c are shown, but one type of these may also be used. Although not shown in the drawings, instead of the pipes 51b and 52b, pipes with reduced diameter may be used. Of course it's a good thing.

[0027]

[Effect of the idea]

The present invention is as described above, and the flow restricting bodies 51 and 52 have the same restricting ratio. When there is, the water flowing in from the raw water inlet 2 is electrolyzed and flows through the acidic ion water outlet 3 and the Lucariion water flows out in a one-to-one ratio with the outflow port 4, but in this case, the diaphragm was omitted. As a result, the contamination of electrolyzed ionized water cannot be completely prevented, so only the efficiency decreases. However, the squeezing ratio changes between the acidic ionized water outlet 3 and the alkaline ionized water outlet 4. When the electrolyzed ionized water is mixed exclusively from one side to the other, it flows in the opposite direction. Most of the contamination in the opposite direction can be avoided. Therefore, for example, when obtaining alkaline ionized water, If you want to increase the amount of alkaline ion water, narrow down the alkaline ion water outlet 4 side more. If the settings are set so that the on-water is mixed into the acidic ionized water side, the acidic ionized water will not be mixed in. The alkaline ionized water flows out from the alkaline ionized water outlet 4, and the diaphragm It is possible to provide an ionized water generator that can be omitted without any problem.

[0028] In addition, mixing ionized water that has been electrolyzed into the other side will result in Although it reduces the electrolytic efficiency, eliminating the diaphragm is good for hygiene and eyesight. It has sufficient practicality in terms of avoiding efficiency loss due to clogging, and what is particularly noteworthy is that , one side of the acidic ionized water outlet 3 and the alkaline ionized water outlet 4 is made larger than the other side. When narrowed down, the anode flat electrode 8 side and the cathode flat electrode 9 side in the electrolytic flow path 7a. A difference also occurs in the flow velocity, and the narrowed side stays in the electric field for a longer time and becomes more ionized. In reality, the decrease in field efficiency was negligible.
