Abstract

PURPOSE:To prevent degradation of taste of generated water by performing stopping of feeding of water by providing a level sensor at a high position than the top opening of an overflow passage and discharging water to keep the water level of a cathode chamber above the water level of an anode chamber. CONSTITUTION:When the water level in a storage tank 14 attains below the specified level, a level sensor detects it and operates a control system to open a feed water valve 11. When the water level in the cathode chamber 3 exceeds the top opening of the overflow passage 12, water begins to enter the anode chamber 4 through the passage 12. When the water level of the anode chamber exceeds the top opening of the passage 12, the levels of both electrode chambers 3, 4 are elevated up to the same level, and the level sensor 13 operates to close the feed water valve 11. A DC voltage is impressed to the electrodes 5, 6, and electrolysis is performed during the time set by a timer, etc.

Description

[Detailed Description of the Invention] The invention relates to an electrolyzed water manufacturing device that generates alkaline ionized water, and in particular, an electrolyzed water manufacturing device that has a configuration for continuously manufacturing electrolyzed water using a purge method. It is related to.

What kind of manufacturing equipment has already been developed by the inventor of the present invention?
The system shown in Figures 1 and 2 was adopted. What can be seen in Figure 1 is that the cathode chamber a and the anode chamber are separated by a partition wall C made of unglazed ceramic, etc., and the electrodes id and e are placed in the bipolar chambers a and b, respectively, and a direct current is applied to the cathode chamber a and the anode chamber. A voltage is applied to cause water electrolysis and electroosmosis, and drain valves f and g are arranged at the bottom of each electrode chamber, and water is supplied to the cathode chamber a. 5. Anode chamber b
K is provided with a level sensor h, and is configured to supply water from the cathode chamber a over the partition wall C to the anode chamber, and the water supply is automatically stopped by the action of the level sensor h. In this manufacturing equipment, a level sensor j is installed in a tank i and a tank When the water used drops below a certain level, this signal is transmitted to a control system (not shown), which performs the sequence of water supply, electrolysis, and drainage. The problem here is that water in the upper part of the cathode chamber a flows over the partition wall C into the anode chamber during the electrolysis process. To understand this problem, we must know the actual situation as follows. As is well known, when electrolysis is carried out, the water level in the cathode chamber a rises due to electroosmosis, and the concentration of hydroxyl ions increases, or the distribution of hydroxyl ions shifts upward. A situation is realized in which the concentration is high at the top and low at the bottom. On the other hand, inside the anode chamber, the water level decreases due to electroosmosis, and a distribution situation in which acidity is high at the top and low at the bottom is realized. Therefore, during electrolysis, when the level in the cathode chamber a rises due to electroosmosis, the part of the water with the highest hydroxyl ion concentration crosses the partition wall C and enters the anode chamber, causing a neutralizing effect. It takes a considerable amount of time to bring the average hydroxyl ion concentration of water within a to a predetermined value, and there are performance disadvantages such as large power loss.

Furthermore, as shown in FIG. 2, a method was adopted in which water was supplied to the anode chamber side and the level sensor h was placed on the cathode chamber a side. In this case, during the initial water supply stage, water is supplied to the cathode chamber a side due to overflow, so scales left on the acidic water side (ABS resin and other resin systems, electrolysis residue, electrode eluate, sulfur, etc.) However, there is a possibility that residual acidic water may enter the cathode chamber A side. Therefore, even if alkaline ionized water with a flavor suitable for drinking is produced in cathode chamber A, the scale that has entered earlier and the residual acidic water may enter the cathode chamber A side. The drawback is that the quality of the taste is significantly reduced by water, etc.

The non-invention was made based on the above circumstances, and although it is an overflow type from the cathode chamber to the anode chamber, it does not reduce the efficiency of increasing the hydroxyl group ion concentration, and moreover, it does not change the taste of the generated alkaline ion water. It is an object of the present invention to provide an apparatus for producing electrolyzed water that does not cause deterioration.

Hereinafter, one embodiment of the present invention will be explained in detail with reference to FIG. In the figure, reference numeral 1 denotes an electrolytic cell that generates drinking water in a purging manner. For example, it is partitioned into two internal and external chambers by a porous partition wall 2 made of cylindrical bisque, and the outside is a cathode chamber 3.
The inner side is an anode chamber 4. And each pole chamber 3.
4 are provided with poles 5 and 6, respectively, and a DC voltage is applied when the switch is turned on.

A drainage valve 7.8 is provided at the bottom of each electrode chamber 3.4 of OX/C1, and a water control valve 9.10 of a water-reinoid type is provided there. In addition, water is supplied to the cathode chamber 3 via the fiber water valve 11, and an overflow passage 12 is formed from the bottom of the cathode chamber 3 to the top of the positive cup chamber 4. It's set up. In this case, the buff flow passage 12 is formed of a tubular body. On the other hand, in the cathode chamber 3, there is provided a repercussion 13 whose contact level with water is higher than that of the top of the overpass 70 and the passage 12.

In the figure, reference numeral 14 denotes a storage tank connected to the drainage channel 7, and a supply column 15 is installed in this tank.
A bell sensor 16 is provided.

Next, I will explain the 11 sequential works of this device. When the water in the storage tank 14 falls below a predetermined level, the level sensor 16 detects this and a control system (not shown) is activated.
(i7 operates to open the water supply valve 11. When the water level in the cathode chamber 3 exceeds the top opening of the over 70 passage 12, water begins to enter the anode chamber 4 through the ±sb passage 12. When the water level in the anode chamber 4 exceeds the top opening of the Yerba flow passage 12, the water level in the two fir chambers 3 and 4 rises to the same level, and the level sensor 13 reaches the level shown in FIG. , close the water supply valve 11, and apply jα to the electrode 5.6.
A current voltage is applied, and electricity is distributed for a set time using a timer or the like.

During this electrolysis process, water moves from the anode chamber 4 to the anode chamber 3 due to frost and permeation, but water refluxes from the cathode chamber 3 to the anode chamber 4 via the overflow passage 12. Unfortunately, there is no difference in water level between anode chambers 3 and 4. Furthermore, since the ocean current of water from the overflow passage to the anode chamber 4 is carried out from the bottom of the anode chamber 3, the water with the lowest ion concentration is refluxed, and the water with the lowest ion concentration is refluxed from the top of the cathode chamber 3. The water portion with a high ion concentration is retained in the cathode chamber 3. Moreover, during electrolysis, the flow of water from the overflow passage 12 is unidirectional, and the water in the anode chamber 4 can only enter the cathode chamber 3 by the action of electric permeation.

When the electrolytic action is completed, the timer (orange) activates the electrode 5.
When the voltage application to the car 6 is released, each drain valve 9.10 is opened, and the alkaline ionized water in the negative 4M chamber 3 is drained into the storage tank 14.
In this implementation evening 11, the acid water on the anode chamber 4 side was
It is discharged via the drain valve 10.

In this embodiment, it is preferable to open the water valve 10 first and delay the opening of the drain valve 9 so that the level of the anode chamber 4 decreases by 1 below the opening of the top of the overflow passage 12. For this purpose, another level sensor 1 is installed in the shade room 3.
It is good to provide 7. During this time, the water at the bottom of the cathode chamber 3 flows through the overflow passage 12 to the positive chamber 4, so that acidic water flows through the overflow passage 12 into the cathode chamber 3.
The amount brought on the side will also be completely l. In addition, the drain valve 9
．． Even if 10 are simultaneously opened, if the water level in the anode chamber 4 is lower than that of the cathode chamber 3 at a high level drop rate, the water level in the anode chamber 4 will be substantially lower than that of the cathode chamber 3 through the overflow oil passage 12.
Water flows from the translation chamber 3 to the anode chamber 4, and conversely, there is no risk that water from the anode chamber 4 will flow into the cathode ♀3 (1!l).

In reality, it is best to devise measures to prevent suction from acting on the bottom opening (ri) of the overflow passage 12, as far as possible from the opening of the drainage channel 7, so that no suction action is applied to the overflow passage 12. As shown, the bottom opening of the overflow passage 12 is located on the opposite side of the drain passage 7.

As described in detail above, the present invention partitions a cathode chamber and an anode chamber with a porous partition, arranges electrodes in both electrode chambers, applies direct current pressure, and controls water electrolysis and electroosmosis. ) In what is now, water supply is 8! vs. house, -c6 not 1.4
□(1) An overflow passage is provided that connects the ag part to the top of the anode chamber, and both bathrooms are configured to drain water from the bottom through multiple drain valves, and a level sensor is installed at the top opening of the overflow passage. <Be sure to stop the water supply before starting the installation, and when you open the drain valve to drain water, the water level in the anode chamber will drop to at least below the top opening of the overflow passage, whereas the water level in the cathode chamber will drop to below the top opening of the overflow passage. Since the water level was set to be 10 times higher than the water level in the anode chamber, the hydroxyl ions mk K
It is hoped that the efficiency of opening the bottle will not be reduced, and since there is no possibility that acidic water will enter the alkaline ionized water side, the taste of the alkaline ionized water will not be impaired.
