Description

Electrolyzed water generator

The present invention relates to an electrolyzed water generating device that generates electrolyzed reduced water and electrolyzed acidic water by electrolyzing water.

Currently, an electrolyzed water generator for home use approved as a medical device is configured to purify tap water and further electrolyze it to generate electrolyzed reduced water and electrolyzed acidic water. The electrolyzed water generating device includes, for example, an electrolyzer having a cathode chamber and an anode chamber separated by a diaphragm, and electrolyzed water is obtained from the cathode chamber and electrolytic acid water is obtained from the anode chamber by electrolysis of water.

However, in such an electrolyzed water generating apparatus, foreign matter adheres to the electrodes (cathode in the cathode chamber and anode in the anode chamber) arranged to face each other as it is used. In particular, metal ions such as calcium contained in water adhere to the surface of the cathode. When such foreign matter adheres to the surface of the electrode, the electrical resistance of the electrode surface increases, and the current flowing through the electrodes arranged oppositely decreases. Thereby, the ion concentration of the electrolytically-reduced water and electrolytic acid water obtained will fall. For this reason, in the conventional electrolyzed water generating apparatus, after using for a certain period of time, it was necessary to clean the electrode by performing the electrolysis with the polarity of the electrode reversed.

For example, in Japanese Patent No. 2618321 (Patent Document 1), the polarity of electrodes is periodically reversed, and the water channel for taking out electrolytic reduced water and electrolytic acid water is switched accordingly (double auto change cross line method). ) Has been proposed. In the electrolyzed water generating device disclosed in Patent Document 1, a first electrode chamber having a first electrode and a second electrode chamber having a second electrode, which are separated by a diaphragm, and for extracting electrolytic reduced water The electrolytically reduced water outlet, the electrolytically acidic water outlet for taking out the electrolytic acidic water, and the electrolytic water generated in the first electrode chamber provided between the first electrode chamber and the electrolytically reduced water outlet. The first water channel that flows toward the electrolytic reduced water outlet, the second electrode chamber and the electrolytic acidic water outlet is provided, and the electrolytic water generated in the second electrode chamber is supplied to the electrolytic acidic water outlet. A second water channel that flows toward the second, a second electrode chamber and the electrolytically reduced water outlet, and a third channel that causes the electrolytic water generated in the second electrode chamber to flow toward the electrolytically reduced water outlet. The electrolyzed water generated in the first electrode chamber is provided between the water channel, the first electrode chamber and the electrolytic acid water outlet, and the electrolytic acid water When the fourth water channel flowing to the outlet and the first water channel and the second water channel are open, the third water channel and the fourth water channel are closed, while the first water channel and the second water channel are closed. When the second water channel is closed, the switching valve for switching the water channel and the supply between the first electrode and the second electrode so that the third water channel and the fourth water channel are opened. And a control means for controlling the switching valve to operate when the voltage is reversed. As a result, even if the polarity of the electrode is reversed and electrolysis is performed for cleaning the electrode surface, electrolytic reduced water is always taken out from the electrolytic reduced water outlet and electrolytic acidic water is taken out from the electrolytic acidic water outlet. An electrolyzed water generating device is provided.

Japanese Patent No. 2618321

In the electrolyzed water generating apparatus that employs the technique disclosed in Patent Document 1, a plurality of water channels (cross lines) are installed before and after the electrolyzer as described above, and the electrolyzer is supplied to the electrolyzer according to the switching of the polarity of the electrode. The inflow path and the outflow path from the electrolytic cell are switched. In such an electrolyzed water generating apparatus, the volume ratio between the first electrode chamber and the second electrode chamber is normally 1: 1 because the volume ratio is alternately switched between the cathode chamber and the anode chamber. In addition, such an electrolyzed water generating device is usually provided with a flow rate adjusting valve before and after the cross line, and is configured so that the water intake ratio between the electrolytically reduced water and the electrolytic acid water can be changed by the flow rate adjusting valve. ing. The intake ratio of electrolytic reduced water and electrolytic acidic water is limited to electrolytic reduced water: electrolytic acidic water = 1: 1 to 5: 1 due to the relationship between the volume ratio of the first electrode chamber and the second electrode chamber. There is a higher ratio of electrolytically reduced water than this, and hypochlorous acid is mixed in the electrolytically reduced water, which is not practical.

The present invention has been made in order to solve the above-mentioned problems, and the object of the present invention is to generate electrolyzed water that can generate electrolytic reduced water at a high water intake ratio without mixing hypochlorous acid. Is to provide a device.

The electrolyzed water generating apparatus of the present invention includes a first electrode chamber including a first electrode and a second electrode chamber including a second electrode, which are separated by a diaphragm, and the diaphragm includes the first electrode and the second electrode chamber. The second electrode is configured to be movable while maintaining a substantially parallel state with respect to the first electrode and the second electrode.

The electrolytic water generator of the present invention includes an electrolytic reduced water outlet for taking out electrolytic reduced water, an electrolytic acidic water outlet for taking out electrolytic acidic water, a first electrode chamber, and an electrolytic reduced water outlet. Provided between the first water channel for flowing the electrolyzed water generated in the first electrode chamber toward the electrolytically reduced water outlet, the second electrode chamber and the electrolytic acid water outlet, 2 is provided between the second water channel for flowing the electrolyzed water generated in the electrode chamber 2 toward the electrolytic acid water outlet, the second electrode chamber and the electrolytically reduced water outlet, and is generated in the second electrode chamber. A third water channel for flowing the electrolyzed water toward the electrolytically reduced water outlet, the first electrode chamber and the electrolytic acid water outlet, and the electrolyzed water generated in the first electrode chamber is electrolyzed When the fourth water channel that flows toward the water outlet, the first water channel, and the second water channel are open, the third water channel and A switching valve for switching the water channel so that the third water channel and the fourth water channel are opened when the fourth water channel is closed and the first water channel and the second water channel are closed; It is preferable that the apparatus further comprises control means for controlling the switching valve to operate when the supply voltage between the first electrode and the second electrode is inverted.

The electrolyzed water generating apparatus of the present invention includes a plurality of alternately arranged first electrode chambers and second electrode chambers, and the first electrode chamber and the second electrode chamber adjacent to each other are diaphragms. It is preferable that at least one of the diaphragms is configured to be movable while maintaining a substantially parallel state with respect to the first electrode and the second electrode.

In the electrolyzed water generating apparatus of the present invention, it is preferable that the diaphragm is configured to move in accordance with a pressure difference between the first electrode chamber and the second electrode chamber adjacent to each other.

According to the present invention, electrolytic reduced water can be generated at a high water intake ratio without mixing in hypochlorous acid, and it is possible to contribute to the environment by reducing the discharge amount of electrolytic acid water.

It is a figure which shows typically the electrolytic cell 1 in the electrolyzed water generating apparatus of a preferable example of this invention. It is a figure which shows typically the state which reversed the polarity of the electrode of the electrolyzed water generating apparatus shown in FIG. It is a schematic diagram for demonstrating the switching of the water channel in a double auto change crossline system. It is a figure which shows typically the electrolytic vessel 51 in the electrolyzed water generating apparatus of the other preferable example of this invention. It is a figure which shows typically the state which reversed the polarity of the electrode of the electrolyzed water generating apparatus shown in FIG.

FIG. 1 is a diagram schematically showing an electrolyzer 1 in an electrolyzed water generating apparatus as a preferred example of the present invention, and FIG. 2 is a schematic diagram showing a state in which the polarity of the electrode of the electrolyzed water generating apparatus shown in FIG. FIG. The electrolyzed water generating apparatus of the present invention includes a first electrode chamber 4 including a first electrode 3 and a second electrode chamber 6 including a second electrode 5 which are separated by a diaphragm 2. The first electrode 3 and the second electrode 5 are configured to be movable while maintaining a substantially parallel state with respect to the first electrode 3 and the second electrode 5.

In the conventional electrolyzed water generator, when the water intake ratio is increased to about electrolytic reduced water: electrolyzed acidic water = 5: 1 or more, hypochlorous acid has been mixed in the electroreduced water. Hypochlorous acid is usually mixed in the electrolytic acid water obtained in the anode chamber, and the water pressure in the cathode chamber is set to be increased during electrolysis. The chamber should be free of hypochlorous acid. However, in reality, hypochlorous acid was mixed in the electrolytically reduced water because the volume ratio of the anode chamber to the cathode chamber in the electrolytic cell was 1: 1, and when the water intake ratio was increased, the cathode chamber The difference in speed between the electrolytically reduced water passing through the anode and the electrolytic acid water passing through the anode chamber becomes larger (the electrolytically reduced water side becomes faster in proportion to the water intake ratio), and this speed difference causes hypochlorous acid to pass through the diaphragm. It is thought that it may be drawn from the anode chamber to the cathode chamber.

On the other hand, in the electrolyzed water generating apparatus of the present invention, the diaphragm 2 can be moved while maintaining a substantially parallel state with respect to the first electrode 3 and the second electrode 5, so that the cathode chamber can be used depending on the situation. The volume ratio between the anode chamber and the anode chamber can be changed to reduce the difference in speed between the electrolytically reduced water and the electrolytic acid water as described above. This provides an electrolyzed water generating apparatus in which hypochlorous acid is not mixed into the electroreduced water even when electroreduced water is taken at a high ratio.

The electrolyzed water generator of the present invention preferably employs a double auto change / cross line system. Here, FIG. 3 is a schematic diagram for explaining the switching of the cross line 10 in the double auto change cross line system. That is, the electrolyzed water generating apparatus of the present invention includes an electrolytic reduced water outlet 11 for taking out electrolytic reduced water and an electrolytic acidic water outlet 12 for taking out electrolytic acidic water. The electrolyzed water generating apparatus of the present invention further includes the following water channel (cross line 10).

A second water channel 14 provided between the second electrode chamber 6 and the electrolytic acid water outlet 12 and allowing the electrolytic water generated in the second electrode chamber 6 to flow toward the electrolytic acid water outlet 12;
A third water channel 15 provided between the second electrode chamber 6 and the electrolytically reduced water outlet 11 and flowing the electrolytic water generated in the second electrode chamber 6 toward the electrolytically reduced water outlet 11;
A fourth water channel 16 that is provided between the first electrode chamber 4 and the electrolytic acid water outlet 12 and allows the electrolytic water generated in the first electrode chamber 4 to flow toward the electrolytic acid water outlet 12.

In the example shown in FIG. 3, the electrolyzed water generating apparatus of the present invention closes the third water channel 15 and the fourth water channel 16 when the first water channel 13 and the second water channel 14 are open (FIG. 3). (A)) On the other hand, when the first water channel 13 and the second water channel 14 are closed, the third water channel 15 and the fourth water channel 16 are opened (FIG. 3B).

For example, FIG. 1 illustrates the case where the first electrode 3 is an anode and the second electrode 5 is a cathode. In this case, the raw water 21 supplied to the first electrode chamber 4 which is an anode chamber is taken out as electrolytic acid water 23 by electrolysis, and the fourth water channel 16 is opened by the switching valve 17 in the state of FIG. Then, it is flowed to the electrolytic acid water outlet 12. On the other hand, the raw water 22 supplied to the second electrode chamber 6 which is a cathode chamber is taken out as electrolytic reduced water 24 by electrolysis, and passes through the third water channel 15 by the switching valve 17 in the state of FIG. And flowed to the electrolytic acid water outlet 12. In this case, when the water intake efficiency of the electrolytic reduced water 24 from the second electrode chamber 6 serving as the cathode chamber is increased, the pressure in the second electrode chamber 6 increases, and the pressure in the direction indicated by the arrow A in FIG. Occurs. In the electrolyzed water generating apparatus of the present invention, at this time, the diaphragm 2 is moved to the first electrode 3 side by the pressure while maintaining a state substantially parallel to the first electrode 3 and the second electrode 5. To do. As a result, the volume of the second electrode chamber 6 that is the cathode chamber can be made larger than that of the first electrode chamber 4 that is the anode chamber, and the water intake efficiency of the electrolytic reduced water 24 is reduced by electrolytic reduced water: electrolytic acidic water. Even if it is raised to about 5: 1 or more, it passes through the electrolytic reduction water 24 passing through the cathode chamber (in this case, the second electrode chamber 6) and the anode chamber (in this case, the first electrode chamber 4). The difference in speed with the electrolytic acid water 23 to be reduced can be reduced, and hypochlorous acid is not mixed into the resulting electrolytic reduced water 24.

FIG. 2 shows an example in which the polarity of the electrode is reversed from that of the example shown in FIG. 1, and the first electrode 3 is a cathode and the second electrode 5 is an anode. In this case, the raw water 21 supplied to the first electrode chamber 4 which is the cathode chamber is taken out as electrolytic reduced water 24 by electrolysis, and the first water channel 13 is opened by the switching valve 17 in the state of FIG. Then, it flows to the electrolytically reduced water outlet 11. On the other hand, the raw water 22 supplied to the second electrode chamber 6 which is an anode chamber is taken out as electrolytic acid water 23 by electrolysis, and passes through the second water channel 14 by the switching valve 17 in the state of FIG. And flowed to the electrolytic acid water outlet 12. In this case, when the water intake efficiency of the electrolytic reduced water 24 from the first electrode chamber 4 serving as the cathode chamber is increased, the pressure in the first electrode chamber 4 increases, and the pressure in the direction indicated by the arrow B in FIG. Occurs. In the electrolyzed water generating apparatus of the present invention, at this time, the diaphragm 2 moves to the second electrode 5 side by the pressure while maintaining a state substantially parallel to the first electrode 3 and the second electrode 5. To do. Thereby, the volume of the 1st electrode chamber 4 which is a cathode chamber can be made larger than the 2nd electrode chamber 6 which is an anode chamber, and the water intake efficiency of the electroreduction water 24 is electroreduction water: electrolysis acidic water Even if it is raised to about 5: 1 or more, it passes through the electrolytically reduced water 24 that passes through the cathode chamber (in this case, the first electrode chamber 4) and the anode chamber (in this case, the second electrode chamber 6). The difference in speed with the electrolytic acid water 23 to be reduced can be reduced, and hypochlorous acid is not mixed into the resulting electrolytic reduced water 24.

The means for allowing the diaphragm 2 to move while maintaining a state substantially parallel to the first electrode 3 and the second electrode 5 is not particularly limited, and can be realized by using conventionally known appropriate means.

Thereby, in the state shown in FIG. 1, the diaphragm 2 moves to the first electrode 3 side as described above, and the upper rib 31a is locked to the packing 32a on the upper first electrode 3 side, and the lower side The rib 31b is engaged with the packing 32b on the lower first electrode 3 side. In the state shown in FIG. 2, the diaphragm 2 moves to the second electrode 5 side as described above, and the upper rib 31a is engaged with the packing 33a on the upper second electrode 5 side. 31b is locked to the packing 33b on the second electrode 5 side. 1 and 2, the diaphragm 2 is held substantially parallel to the first electrode 3 and the second electrode 4. Thus, in the electrolyzed water generating apparatus of this invention, the diaphragm 2 is comprised so that it may move according to the pressure difference between the 1st electrode chamber 4 and the 2nd electrode chamber 6 which are mutually adjacent | abutted.
