DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolyzed water generating apparatus having a processing means for processing harmful gas generated in an electrolyzer for electrolyzing water to be electrolyzed to generate electrolyzed water.

[0002]

2. Description of the Related Art An electrolyzed water generator is connected to a water supply facility such as a water supply, and performs electrolysis in a flowing water state to generate acidic water or alkaline water. There is a batch method in which water is electrolyzed in a stagnant state. The flowing water method has the merit that the electrolyzed water can be immediately taken.However, when trying to obtain acidic water with strong oxidizing power or alkaline water with strong reducing power, the electrode needs to be large, large power is required, and it is complicated. This necessitates a simple configuration, and increases the cost of the entire apparatus. On the other hand, in the batch method, electrolysis is performed in a stagnant state, so that electrolysis can be performed for a long time, and the above-mentioned acidic water or alkaline water can be easily obtained with a simple configuration.

[0003] As a conventional electrolyzed water generating apparatus, Japanese Patent Application Laid-Open No. HEI 1-1990 discloses an example which can efficiently generate electrolyzed water even in a flowing water system.
There was the one described in Japanese Patent Application Laid-Open No. 0-472. As shown in FIG. 5, this electrolyzed water generating apparatus is provided with electrode plates 2 and 3 opposed to the inside of an electrolytic cell 1 through which raw water such as tap water or well water flows. It is configured to be added by the pump 5. Reference numeral 6 denotes a diaphragm, 7 denotes a raw water supply channel, 8 denotes a first drain pipe, 9 denotes a second drain pipe, 10 denotes a forward / reverse voltage switch, and 11 denotes a DC power supply.

In this configuration, the salt (NaCl), which is an electrolyte to be added, lowers the electric resistance of raw water to lower the voltage at the time of electrolysis, stabilizes the electrolysis efficiently, and removes the salt by electrolysis. It acts to supply chlorine ions for producing hypochlorous acid (HClO) having bacterial power.

When the hypochlorous acid (HClO) is generated, chlorine gas, which is a harmful gas, is generated by an anodic reaction of the electrode plates 2 and 3 in the aqueous salt solution. In particular, the electrode 2 of the electrolytic cell 1,
When the pH value on the anode side of 3 decreases, chlorine gas is also generated from the electrolyzed water itself. The chlorine gas has a strong oxidizing effect and causes problems such as corroding a metal surface and the like and having a pungent odor.

Therefore, there is a conventional harmful gas processing apparatus as disclosed in Japanese Patent Application Laid-Open No. 9-329570. As shown in FIG. 6, this harmful gas processing apparatus is configured to send chlorine gas generated around the electrode 11 together with the electrolytic solution 12 to the harmful gas purifying member 14 by the suction pump 13 for processing. Further, the chlorine gas released from the liquid surface of the electrolytic solution 12 was sent to the chlorine gas adsorbing member 16 by the exhaust fan 15 for processing. It is shown that a catalyst or activated carbon is used for the harmful gas purifying member 14 and the chlorine gas adsorbing member 16.

[0007]

However, in the conventional structure described in the above-mentioned Japanese Patent Application Laid-Open No. 9-329570, it is not possible to carry out a sufficient treatment of harmful gases unless the suction pump and the exhaust fan are driven. In addition to the complicated structure, the device is expensive because it needs to have a structure that can withstand chlorine gas. In addition, catalysts and activated carbon are inconvenient because they have a short life and require periodic replacement.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide an electrolyzed water generating apparatus capable of treating a harmful gas with a simple configuration.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 shows a configuration diagram of an electrolyzed water generating apparatus according to Embodiment 1 of the present invention. This embodiment shows a case where alkaline water is collected as electrolyzed water and used as washing water. In the figure, reference numeral 20 denotes an electrolytic cell, and a diaphragm 21
Thus, an anode chamber 22 and a cathode chamber 23 are formed, and an anode 24 and a cathode 25 are respectively opposed to each other with a diaphragm 21 therebetween. An anode water outlet 26 and a cathode water outlet 27 are provided below the electrolytic cell.

Above the electrolytic cell 20, there are provided liquid holding means 28 for dissolving chlorine gas, which is a harmful gas generated from the anode chamber 22, and liquid supply means 29 for supplying a liquid to the liquid holding means 28. And the liquid holding means 28
Is made to penetrate and hold the liquid in the liquid holdings 2A and 28B divided into upper and lower parts. The liquid here refers to the electrolytic cell 20
Tap water and groundwater, which are electrolyzed water supplied to
Write water.

The electrolytic gas generated from the electrolytic cell 20 passes through the liquid holding liquids 28A and 28B and is exhausted from the exhaust port 30.
During this time, gases that are difficult to dissolve in water, such as oxygen gas and hydrogen gas, are exhausted from the exhaust port 30, and chlorine gas that is easily soluble in water comes into contact with and dissolves in the water contained in the liquid retention liquids 28A and 28B.

Numeral 31 is provided at the upper end of the electrolytic cell 20,
0 is a lid that opens and closes, and is insulated about the hinge 31A to open and close. When supplying water to the electrolytic cell, the lid 31 is opened and poured, and when performing electrolysis, the lid 31 is closed. The exhaust port 30 is provided on the upper surface of the lid 31, and the liquid retention 28A is attached to the inner surface thereof.
Is opened and closed together with the lid 31 at the time of opening and closing.

The liquid supply means 29 is configured to open the lid 31 before the electrolysis, divide the liquid holding liquid 28A and the liquid holding liquid 28B, and pour water onto the liquid holding liquid 28B. And the storage container 32 which stores the water supplied to the electrolytic tank 20 is provided, and the bottom part of the liquid retention 28B is immersed in the water of the storage container 32 and permeated. Then, when the lid is closed, the water that has permeated into the liquid retention liquid 28B comes into contact with the liquid retention liquid 28A, is sucked up by capillary action, penetrates into the liquid retention liquid 28A, and the water spreads throughout.

The liquid holding liquids 28A and 28B are made of a sponge made of a polyethylene foam, which is a chlorine-resistant material, which is formed into a continuously foamed porous body so that the electrolytic gas can pass through and water can be contained. Reference numeral 33 denotes an electrolyte tank having a detachable cap 34 and an electrolyte bed 35, in which salt is filled as an electrolyte. Raw water introduced into the electrolytic tank 20 by a pulse pump 37 from a water supply port 36 provided in the anode chamber 22 is introduced into the electrolyte tank 33 through an introduction path 38.
Through the electrolyte tank 33. The introduced water is mixed with salt to form a supersaturated saline solution, and the electrolyte bed 35
The electrolyte solution is supplied from the electrolyte supply port 40 through the liquid supply passage 39 to the anode chamber 22.

Here, a check valve 41 is provided near the electrolyte supply port 40 of the liquid supply passage 39 in a direction for preventing intrusion of raw water in the anode chamber 22. It is provided above the liquid level.

A discharge means 42 is provided downstream of the cathode water outlet 27. Cathode water is taken from the discharge port 44 into the electrolytic water container 45 through the discharge path 43 by being driven.
A drain valve 47 for discharging anode water through a drain passage 46 is provided downstream of the anode water outlet 26.

Numeral 48 denotes control means comprising an operation panel 49 and a control circuit 50. A signal from a container detecting means 51 for detecting the presence of the electrolyzed water container 45 is input to the control circuit 50, and the container detecting means 51 discharges the container. It is configured to perform the electrolysis operation only when it is located at a position facing the outlet 44.
Numeral 52 is a pulse counter for counting the driving pulses of the liquid supply means 37 composed of a pulse pump. The consumption of salt is detected in a simulated manner by counting the number of accumulated pulses. It is configured to provide notification of replenishment.

The operation panel 49 has a power switch, an electrolytic switch, and a container detecting means 51 for notifying the presence of the electrolyzed water container by means of the container detecting means 51. It has a salt supply notifying means for notifying (not shown).

Next, the operation and operation of the above configuration will be described. Before the electrolysis, the lid 31 is opened and water is poured into the electrolytic cell 20. At this time, the water mainly flows along the upper surface of the liquid retention liquid 28 </ b> B and is poured into the anode chamber 22. Part of the water also accumulates in the storage container 32 while penetrating into the liquid retention liquid 28B. Then, water is further poured, and the water overflowing the anode chamber 22 enters the cathode chamber 23 and is filled up to a predetermined water level in the cathode chamber 23. Here, when the lid 31 is closed, the upper surface of the liquid retention 28B and the lower surface of the liquid retention 28A come into contact, and the water of the liquid retention 28B permeates also into the liquid retention 28A.

Next, the power supply switch of the operation panel 47 is turned on, and the electrolysis operation is started by turning on the electrolysis switch. At this time, if the electrolyzed water container 35 is set at a predetermined position, the container set notification means on the operation panel 47 is turned on, and the electrolysis operation is started. When the electrolyzed water container 43 is not placed at a position facing the discharge port 42, the electrolyzed water container 43 is detected by the container detection means 49, and does not shift to the electrolysis operation. As a result, it is possible to prevent the electrolytic water from being discharged to the outside of the container by mistake.

The electrolysis operation will be described. When the electrolytic switch 44 is turned on, first, the salt supply means 35 is driven for a predetermined time, and the raw water in the anode chamber 22 is sent to the electrolyte tank 31 via the introduction path 36. The electrolyte tank 31 is configured in a watertight state. When the raw water is introduced, the supersaturated saline solution flows from the electrolyte supply port 38 into the anode chamber 22 through the electrolyte bed 32, the liquid supply path 37, and the check valve 39. A predetermined amount is supplied, and it becomes salt dilution water of a predetermined concentration. Next, the control circuit 48
Operates to apply a current between the anode 24 and the cathode 25 in reverse polarity, that is, with the anode 24 side being a minus pole and the cathode 25 side being a plus pole for a predetermined time. Thus, the scale component deposited on the surface of the cathode 25 by the previous electrolysis is oxidized and reduced and washed. In other words, raw water contains various ions,
In particular, cations such as calcium ions and magnesium ions react with hydroxyl groups in the cathode chamber 23 to form calcium hydroxide and magnesium hydroxide. When the cations exceed the solubility limit, they are deposited on the surface of the cathode 25 and the diaphragm 21 and interfere with the electrolytic current. However, by performing the reverse voltage cleaning for a predetermined time before the electrolysis, the cleaning is performed well, the scale component is decomposed, and the life of the electrode can be extended.

After that, it is electrolyzed with a normal polarity for a predetermined time. In the anode chamber 22 during electrolysis, the reaction shown in (Chem. 1) occurs to generate acidic water.

(Chemical Formula 1) 2Cl ⁻ → Cl ₂ ↑ + 2e ^- Cl ₂ + H ₂ O → HCl + HClO 2H ₂ O → O ₂ ↑ + 4H ⁺ + 4e ^- On the other hand, in the cathode chamber 23, the reaction shown in Chemical Formula 2 occurs to form hydroxyl groups. Na ⁺ moves through the diaphragm 21 to neutralize OH ⁻ , generating alkaline water.

(2) 2H ₂ O + 2e ⁻ → H ₂ ↑ + 2OH ⁻ Na ⁺ + e ₋ → Na 2Na + 2H ₂ O → 2NaOH + H ₂ ↑ Here, since the salt solution is supplied only to the anode chamber 22, the reducing power is reduced in a short time. Strong alkaline water is obtained. That is,
When a voltage is applied between the anode 24 and the cathode 25, the ions contained in the water to be electrolyzed become positive / negative 24, 25
The ions of the opposite polarity move through the diaphragm 21. Therefore, Na ions contained in the salt introduced into the anode chamber 22 immediately move to the cathode chamber 25 via the diaphragm 21. In addition to the electric attractive force, for example, according to the diffusion theory, Na ions act to make the ion concentration uniform by diffusion. As a result, the current flowing between the positive / negative electrodes 24 and 25 increases, and alkaline water having a strong reducing power can be obtained in a short time. According to the experiment, 500 cc of water at 15
By electrolyzing for minutes, alkaline water having a pH of 12 was obtained. The alkaline water having a strong reducing power has a saponifying or emulsifying effect on fats and oils and a hydrolyzing effect on proteins, and can be used as washing water for surfaces of furniture, house building materials, electric appliances and the like.

Further the cathode chamber 23 by saline solution only to the anode chamber 22 is supplied chlorine ions Cl ^- produced low density alkaline water. Since Cl ^- is a factor that impairs the detergency, alkaline water having a high detergency can be generated by supplying the salt solution only to the anode chamber 22.

After the alkaline water generated in the cathode chamber 14 is electrolyzed for a predetermined time, the water discharging means 32 is immediately driven to be injected into the electrolytic water container 35 from the discharge port 34 through the discharge path 33. Thereby, permeation and mixing of acidic water and alkaline water through the electrolytic diaphragm can be prevented, the deterioration of the pH value can be prevented, and erroneous ejection in the absence of a container can be prevented. The electrolyzed water container 35 may be provided with a spray mechanism (not shown) so that it can be sprayed directly onto the surface to be cleaned.

The acidic water generated in the anode chamber 22 is supplied to the drain valve 4
5 is opened and discharged through the drainage channel 44.
The acidic water generated at the same time has a bactericidal action and can be used as germicidal water. It can also be mixed with alkaline water at a predetermined ratio and used as neutral or weakly acidic sterilized water.

When electrolysis is performed in the electrolytic cell 20, the anode chamber 2
2 produces acidic water, and the cathode chamber 23 contains alkaline water.
At the same time, chlorine gas is
Cl _Two↑, oxygen gas O_Two↑ is generated in the cathode chamber 23 and
Hydrogen gas H_Two↑ is generated (in this embodiment,
Are collectively called an electrolytic gas). Electrolytic gas generated here
Accumulates above acidic water and alkaline water,
Therefore, the liquid passes through the inside of the liquid holding parts 28A and 28B. Liquid retention
Components soluble in water in electrolytic gas inside 28A and 28B
Dissolves. Chlorine gas dissolves in water, so remove it here
Is done. Insoluble components such as oxygen gas and hydrogen gas
Most of them pass through the interior of the liquid holding devices 28A and 28B.
The gas is discharged from the exhaust port 30 to the outside of the apparatus. Anode compartment 22
And sufficient concentration of acidic water and alkaline water in the cathode 23
When it is completed, the power supply to the electrodes 24 and 25 is stopped.
After that, when performing electrolysis again, open the electrolytic cell lid 20A and again
Is supplied, the liquid holding means 28A, 28A of the liquid holding means 28
The chlorine component (hypochlorous acid) dissolved in B is electrolyzed together with water
It can flow out to the tank 20 and maintain the chlorine gas removal performance.
it can. Thus, chlorine gas generated by electrolysis leaks.
The liquid enters the liquid holding means 28 without leaking, and is removed by dissolution.
Chlorine gas in the atmosphere where the device is being used.
Since the concentration does not increase, there is no irritating odor and it is used comfortably.
Can be used.

The gas containing chlorine gas generated in the electrolytic cell 20 passes through the inside of the continuous foam of the liquid holding means 28 due to its own pressure rise, and is dissolved while contacting a liquid capable of dissolving chlorine gas. Therefore, the total amount of chlorine gas generated by the electrolysis and leaking to the outside of the electrolytic cell comes into contact with the liquid having a large surface area, so that the chlorine gas can be efficiently removed.

The liquid supply means 29 uses the liquid for dissolving the chlorine gas as the water to be electrolyzed,
Since water is automatically supplied when water is supplied, the liquid for dissolving the chlorine gas is not consumed, so that the chlorine gas can be reliably removed.

In the present embodiment, the electrolyzed water is used as the liquid for dissolving the chlorine gas. However, any liquid that dissolves the chlorine gas may be an organic solvent, oil or fat, or a mixture thereof.

Even when water is used, most of the dissolved chlorine gas becomes hypochlorite ion when it becomes alkaline, and the abundance of water rapidly increases from neutral (pH 7). It is better to lean to the alkaline side even a little. If possible, the pH may be 8.0 or more. Therefore,
Alkaline water generated on the cathode side may be used. In this way, when the liquid is made alkaline, the mixed chlorine gas is easily dissolved and becomes hypochlorite ion, so that the dissolved chlorine gas is not generated again, so that the chlorine gas is reliably removed. Can be.

Further, in order to further improve the performance of the chlorine gas removing means, it is only necessary to add hypochlorous acid and an agent for decomposing hypochlorite ions generated by dissolving chlorine gas in water. Such agents include ascorbic acid, polyphenols, calcium sulfite, sodium thiosulfate, iron oxide, manganese solution, calcium carbonate compounds, proteins and organic substances reactive with hypochlorite compounds. By adding these agents, these compounds are decomposed, so that the concentration in the solution can be maintained at a lower level than the saturation concentration of hypochlorous acid and hypochlorite ion, and the dissolving performance can be improved. Can be maintained,
Even if the liquid holding means touches the hand, no chlorine is felt or the skin becomes rough. Therefore, since the agent capable of decomposing the chlorate compound is dissolved in the liquid, the chlorate compound generated by dissolving the chlorine gas can be chlorided, so that the concentration of the chlorate compound in the liquid is always low. Since it is possible at the level, there is no leakage of chlorine gas from the chlorine removing means, so that chlorine gas can be reliably removed.

Since the amount of chlorine gas dissolved in water can be increased, the effect of removing chlorine gas can be improved.

In this embodiment, as the liquid holding means for holding the liquid in the liquid holding means, continuous expanded polyethylene is used, but a nonwoven fabric or a cotton-like fiber aggregate may be used. In this case, unlike the foam, the ratio of the voids as the liquid retaining liquid can be increased, so that the permeability of the liquid is improved, and the passage resistance of the electrolytic gas can be reduced, so that the smooth exhaust can be performed. Further, the fiber aggregate is a collection of a plurality of fibers, and a narrow or wide gap between fibers is crowded together. In a narrow portion of the gap, the liquid acts so as to be easily permeated and held by a capillary phenomenon. On the other hand, where the gap is wide, the harmful gas easily permeates and penetrates, and the liquid and the harmful gas have a structure that easily contacts inside the fiber assembly.
