Description

Hereinafter, Tables 1 and 2 are shown with respect to Examples 1 to 8 and Comparative Examples 1 to 12 of the present invention for generating water containing fine bubbles of ozone-containing oxygen and hydrogen using the above-mentioned fine bubble-containing water generator 1. Although described with reference to the present invention, it goes without saying that the present invention is not limited to the following examples.

(Examples 1 to 8 and Comparative Examples 1 to 12)
As shown in Table 1, in Examples 1 to 8 and Comparative Examples 2 to 12, electrolysis in which 1 [L] of water at 20 ° C. was introduced into the storage tank 10 and immersed in the water stored in the storage tank 10. By applying a DC voltage of 12 [V] between the electrodes (anodide 22 and cathode 23) of the element 21 for 10 minutes, ozone-containing oxygen bubbles and hydrogen bubbles are generated in the stored water in the storage tank 10, and then the vibrator is used. By 31, vibration was continuously applied to the stored water in the storage tank 10 for 1 minute. The frequency, amplitude and intensity of the vibration applied to the water by the vibrator 31 at this time are as shown in Table 1. On the other hand, as shown in Table 1, for Comparative Example 1, 1 [L] of water at 20 ° C. was introduced into the storage tank 10, and a DC voltage of 12 [V] was applied between the electrodes of the electrolytic element 21 for 10 minutes. By doing so, ozone-containing oxygen bubbles and hydrogen bubbles were generated in the stored water in the storage tank 10, but no vibration was applied.

Regarding the vibration amplitude, the amplitude voltage V generated by the unimorph type piezoelectric element (C-8 manufactured by Fuji Ceramics Corporation) immersed in the water in the storage tank 10 in response to the vibration applied by the vibrator 31. Was measured, and it was calculated from the following equation (2) from the measured amplitude voltage V and the equivalent piezoelectric constant d31 of the piezoelectric element.
A = d ₃₁ x V ... (2)
A: Amplitude [m]
d ₃₁ : Equivalent piezoelectric constant [m / V] (= -274 × ^10-12 )
V: Measured amplitude voltage [V]

The vibration intensity was calculated from the lower equation (3) from the frequency of the vibration applied to the water by the vibrator 31 and the amplitude calculated from the upper equation (2).
I=(2π×f×A) ² ×Z ₀ /2 (3)
I: Strength [W / m ² ]
f: Frequency [Hz]
A: Amplitude [m]
Z ₀ : Acoustic impedance of water (=1.6×10 ⁶ [kg/(cm ² ·s)])

For Examples 1 to 8 and Comparative Examples 2 to 12 in which vibration was applied after the generation of ozone-containing oxygen and hydrogen, the state of the generated water before and after the application of vibration was applied, and the vibration was applied after the generation of ozone-containing oxygen and hydrogen. In Comparative Example 1 in which the voltage was not applied to the electrolytic element 21, the state of the produced water was visually confirmed, and the state is shown in Table 2. Further, with respect to Examples 1 to 8 and Comparative Examples 2 to 12 in which vibration was applied after the generation of ozone-containing oxygen and hydrogen, ozone-containing oxygen and ozone-containing oxygen and the time after 15 minutes had passed after the application of vibration by the vibrator 31 was stopped. In Comparative Example 1 in which vibration was not applied after the generation of hydrogen, the bubble diameter (mode diameter) and the number of fine bubbles contained in the generated water were nano-sized when 15 minutes had passed after the voltage application to the electrolytic element 21 was stopped. Measurements were made using a particle analysis system (Nanosite LM10 manufactured by Malvern), and the results are shown in Table 2.

As can be seen from Table 2, in Examples 1 to 8 in which the intensity I of the vibration applied by the vibrator 31 is 8.56 × 10 ¹² [W / m ² ] or more, the generated water that was cloudy before the vibration was applied. After the vibration was applied, it became transparent, and in 1 ml of the obtained generated water, 5.1 × 10 ⁸ to 8.6 × 10 ⁸ ozone-containing oxygen-containing fine bubbles and hydrogen fine bubbles having an average bubble diameter of about 100 nm were found. It was confirmed that it exists. Before the application of vibration, the generated water becomes cloudy due to the large diameter of ozone-containing oxygen bubbles and hydrogen bubbles, but vibration with an intensity I of 8.56 × 10 ¹² [W / m ² ] or more is applied to this generated water. It is probable that the diameter of the ozone-containing oxygen bubbles and the hydrogen bubbles was reduced to about 100 nm, and the generated water became transparent.

In particular, in Examples 2, 4, 6 and 8 in which the intensity I of the vibration applied by the vibrator 31 is less than 1.00 × 10 ¹³ [W / m ² ], the cloudy generated water is completely transparent. It took about 30 seconds from the start of application of vibration, but the intensity I of the vibration applied by the vibrator 31 was 1.00 × 10 ¹³ [W / m ² ] or more. Examples 1, 3, 5, 7 As for, it becomes transparent immediately after the vibration is applied, and if the intensity I of the applied vibration is set to 1.00 × 10 ¹³ [W / m ² ] or more, ozone-containing oxygen-containing fine cells having an average cell diameter of about 100 nm. And hydrogen microbubbles can be generated faster.

On the other hand, in Comparative Example 1 in which the vibration was not applied and Comparative Examples 2 to 12 in which the intensity I of the applied vibration was less than 8.56×10 ¹² [W/m ² ], the generated water was obtained. Is still cloudy, and it is considered that a large amount of ozone-containing oxygen bubbles of 3 μm or more and hydrogen bubbles are generated. Therefore, the above-mentioned nanoparticle analysis system cannot measure the bubble size and the number of nano-sized fine bubbles.

In the fine bubble-containing water generator 1, the electrolytic element 21 is held at the bottom of the storage tank 10, and the vibrator 31 that vibrates the water stored in the storage tank 10 is placed in the upper opening of the storage tank 10. Although it is held via the fixed support plate 32, the present invention is not limited to this. For example, as shown in FIG. 4, the oscillator 31 is fixed to the inside of a hermetically sealed case 34 by adhesive bonding. The oscillator of the above may be adopted, and the electrolytic element 21 may be attached to the top surface of the case 34. Moreover, as shown in FIG. 5, a directional oscillator 31 may be attached to a predetermined position in the storage tank 10 so that the traveling direction of the vibration is directed to the electrolytic element 21.

FIG. 6 shows another embodiment. This fine bubble-containing water generation device 2 includes a storage tank 10 for storing water, an electrolytic element 21 and a DC power supply device 26 for electrolyzing water to generate (oxygen and hydrogen) or (ozone-containing oxygen and hydrogen). The above-mentioned fine bubble-containing material is included in that it is provided with the water electrolysis gas generating means 20 having the above and the vibration applying means 30 having the vibrator and the oscillating device 33 for applying vibration to the water stored in the storage tank 10. Although having the same configuration as the water generator 1, the storage tank 10 includes an anode-side storage part PS in which stored water contacts only the anode 22 of the electrolytic element 21 with the electrolytic element 21 as a part of the partition wall. Anode-side oscillator 31p that divides the stored water into a cathode-side storage portion NS that contacts only the cathode 23 of the electrolytic element 21 and applies vibration to the stored water in the anode-side storage portion PS, and stored water in the cathode-side storage portion NS The configuration is different from that of the fine bubble-containing water generator 1 in that each of the anode-side transducers 31n for applying vibration to the surface is provided.

Therefore, in this fine bubble-containing water generator 2, ozone-containing oxygen fine bubble-containing water or oxygen fine bubble-containing water is stored in the anode side storage part PS of the storage tank 10, and hydrogen fine bubbles are stored in the cathode side storage part NS of the storage tank 10.

Examples 17 to 24 and Comparative Examples 25 to 36, Examples 25 to 32 and Comparative Examples 37 to 48 of the present invention for producing water containing hydrogen fine bubbles will be described with reference to Tables 3 to 8. It goes without saying that the present invention is not limited to the following examples.

(Examples 9 to 16 and Comparative Examples 13 to 24)
As shown in Table 3, for Examples 9 to 16 and Comparative Examples 14 to 24, 0.5 [L] of water at 20° C. was introduced into the anode side storage part PS of the storage tank 10, and the anode side storage part By applying a DC voltage of 12 [V] between the electrodes (anode 22 and cathode 23) of the electrolytic element 21 in which the anode 22 is in contact with the water stored in the PS for 10 minutes, the inside of the anode-side storage portion PS After generating ozone-containing oxygen bubbles in the stored water, vibration was continuously applied to the stored water in the anode-side storage portion PS by the anode-side vibrator 31p for 1 minute. Table 3 shows the frequency, amplitude, and intensity of the vibration applied to the water by the anode-side vibrator 31p at this time. On the other hand, as shown in Table 3, in Comparative Example 13, 0.5 [L] of water at 20° C. was introduced into the anode-side storage part PS of the storage tank 10 and 12 [V] was applied between the electrodes of the electrolytic element 21. By applying the DC voltage of 10 minutes for 10 minutes, ozone-containing oxygen bubbles were generated in the stored water in the anode side storage part PS, but no vibration was applied.

Regarding the vibration amplitude, a unimorph type piezoelectric element (C-8 manufactured by Fuji Ceramics Corporation) immersed in water in the anode side storage portion PS of the storage tank 10 applies vibration by the anode side vibrator 31p. The amplitude voltage V generated in response to the measurement is measured, and the measured amplitude voltage V and the equivalent piezoelectric constant d31 of the piezoelectric element are calculated from the above equation (2). Regarding the vibration intensity, the anode side vibrator 31p is water. It was calculated from the above-mentioned equation (3) from the frequency of the vibration applied to the above and the amplitude calculated from the above-mentioned equation (2).

Regarding Examples 9 to 16 and Comparative Examples 14 to 24 in which vibration was applied after the generation of ozone-containing oxygen, the states of the produced water before and after the application of vibration were compared, and in Comparative Example 13 in which the vibration was not applied after generation of ozone-containing oxygen. The state of the generated water at the time when the voltage application to the electrolytic element 21 was stopped was visually confirmed, and the state is shown in Table 4. Further, in Examples 9 to 16 and Comparative Examples 14 to 24 in which vibration was applied after the generation of ozone-containing oxygen, 15 minutes after the application of vibration by the anode-side vibrator 31p was stopped, after the generation of ozone-containing oxygen. For Comparative Example 13 in which no vibration was applied, the bubble diameter (mode diameter) and the number of the fine bubbles contained in the generated water were measured at the nanoparticle analysis system (at 15 minutes after the voltage application to the electrolytic element 21 was stopped). Measurements were made using Malvern nanosite LM10), and the results are shown in Table 4.

As can be seen from Table 4, Examples 9 to 16 in which the intensity I of the vibration applied by the anode-side vibrator 31p was 8.56 × 10 ¹² [W / m ² ] or more were cloudy before the vibration was applied. The generated water became transparent after vibration was applied, and in 1 ml of the obtained generated water, 6.7 × 10 ⁸ to 9.5 × 10 ⁸ ozone-containing oxygen-containing fine bubbles having an average cell diameter of about 100 nm were present. I was able to confirm that. Before the application of vibration, the generated water becomes cloudy due to the large diameter of the ozone-containing oxygen bubbles. However, by applying vibration with a strength I of 8.56 × 10 ¹² [W / m ² ] or more to this generated water, It is considered that the bubble diameter of the ozone-containing oxygen bubbles was reduced to around 100 nm, and the resulting water became transparent.

Particularly, in Examples 10, 12, 14, and ^{16 in} which the intensity I of the applied vibration by the anode-side vibrator 31p is lower than 1.00×10 ¹³ [W/m ² ], the white turbid generated water is completely generated. It took about 30 seconds from the start of the application of vibration until it became transparent, but the intensity I of the applied vibration by the anode-side vibrator 31p was 1.00×10 ¹³ [W/m ² ] or more. , 13 and 15 are transparent immediately after the vibration is applied, and when the intensity I of the applied vibration is 1.00×10 ¹³ [W/m ² ] or more, the average bubble diameter of about 100 nm is included. Ozone oxygen fine bubbles can be generated faster.

On the other hand, in Comparative Example 13 in which no vibration was applied and Comparative Examples 14 to 24 in which the intensity I of the applied vibration was less than 8.56 × 10 ¹² [W / m ² ], the obtained generated water was obtained. Is still cloudy, and it is considered that a large amount of ozone-containing oxygen bubbles of 3 μm or more are generated. Therefore, the above-mentioned nanoparticle analysis system cannot measure the bubble size and the number of nano-sized fine bubbles.

(Examples 17 to 24 and Comparative Examples 25 to 36)
As shown in Table 5, in Examples 17 to 24 and Comparative Examples 26 to 36, 0.5 [L] of water at 20 ° C. was introduced into the anode side storage portion PS of the storage tank 10, and 0.5 [L] of water was introduced into the anode side storage portion PS. Storage in the anode side storage unit PS by applying a DC voltage of 1.23 [V] between the electrodes (anode 22 and cathode 23) of the electrolytic element 21 in which the anode 22 is in contact with the stored water in the room for 10 minutes. After generating oxygen bubbles in the water, vibration was continuously applied to the stored water in the anode-side storage portion PS for 1 minute by the anode-side transducer 31p. The frequency, amplitude and intensity of the vibration applied to the water by the anode side oscillator 31p at this time are as shown in Table 5. On the other hand, as shown in Table 5, in Comparative Example 25, 0.5 [L] of water at 20 ° C. was introduced into the anode-side storage portion PS of the storage tank 10 and 1.23 between the electrodes of the electrolytic element 21. By applying the DC voltage of [V] for 10 minutes, oxygen bubbles were generated in the stored water in the anode side storage portion PS, but no vibration was applied.

The amplitude and intensity of vibration were calculated in the same manner as in Examples 9 to 16 and Comparative Examples 13 to 24.

For Examples 17 to 24 and Comparative Examples 26 to 36 in which vibration was applied after oxygen generation, the state of the generated water before and after the vibration was applied, and in Comparative Example 25 in which vibration was not applied after oxygen generation, the electrolytic element was used. The state of the generated water at the time when the voltage application to the 21 was stopped was visually confirmed, and the state is shown in Table 6. Further, in Examples 17 to 24 and Comparative Examples 26 to 36 in which the vibration was applied after the oxygen was generated, the vibration was applied after the oxygen was generated 15 minutes after the application of the vibration by the anode side vibrator 31p was stopped. In Comparative Example 25, which did not, the particle diameter (mode diameter) and the number of fine bubbles contained in the generated water were determined by the nanoparticle analysis system (Nanosite manufactured by Malvern) 15 minutes after the voltage application to the electrolytic element 21 was stopped. The measurement was performed using LM10), and the results are shown in Table 6.

As can be seen from Table 6, Examples 17 to 24 in which the intensity I of the vibration applied by the anode-side vibrator 31p was 8.56 × 10 ¹² [W / m ² ] or more were cloudy before the vibration was applied. The generated water became transparent after the application of vibration, and in 1 ml of the obtained generated water, 4.3 × 10 ⁷ to 8.8 × 10 ⁷ oxygen fine bubbles having an average cell diameter of about 100 nm were present. I was able to confirm that. Before the vibration is applied, the generated water becomes cloudy due to the large diameter of the oxygen bubbles. However, by applying vibration with a strength I of 8.56 × 10 ¹² [W / m ² ] or more to the generated water, the oxygen bubbles are generated. It is considered that the bubble diameter of the water was reduced to around 100 nm, and the resulting water became transparent.

Particularly, in Examples 18, 20, 22, and 24 in which the intensity I of the applied vibration by the anode-side vibrator 31p is lower than 1.00×10 ¹³ [W/m ² ], the white turbid generated water is completely generated. It took about 30 seconds from the start of application of the vibration until it became transparent, but the intensity I of the applied vibration by the anode-side vibrator 31p was 1.00×10 ¹³ [W/m ² ] or more. , 21 and 23 are transparent immediately after the vibration is applied, and when the intensity I of the applied vibration is 1.00×10 ¹³ [W/m ² ] or more, the average bubble diameter of about 100 nm is included. Ozone fine bubbles can be generated faster.

On the other hand, in Comparative Example 25 in which no vibration was applied and Comparative Examples 26 to 36 in which the intensity I of the applied vibration was less than 8.56 × 10 ¹² [W / m ² ], the obtained generated water was obtained. Is still cloudy, and it is considered that a large amount of oxygen bubbles of 3 μm or more are generated. Therefore, the above-mentioned nanoparticle analysis system cannot measure the bubble size and the number of nano-sized fine bubbles.

(Examples 25 to 32 and Comparative Examples 37 to 48)
As shown in Table 7, for Examples 25 to 32 and Comparative Examples 38 to 48, 0.5 [L] of water at 20° C. was added to the anode side storage part PS and the cathode side storage part NS of the storage tank 10, respectively. 6 between the electrodes (anode 22 and cathode 23) of the electrolytic element 21 in which the anode 22 is in contact with the stored water in the anode side storage portion PS and the cathode 23 is in contact with the stored water in the cathode side storage portion NS. After applying a DC voltage of [V] for 10 minutes to generate hydrogen bubbles in the stored water in the cathode side storage portion NS, the cathode side vibrator 31n vibrates the stored water in the cathode side storage portion NS. It was applied continuously for 1 minute. Table 7 shows the frequency, amplitude, and intensity of the vibration applied to the water by the cathode-side vibrator 31n at this time. On the other hand, as shown in Table 7, in Comparative Example 37, 0.5 [L] of water at 20° C. was introduced into the anode-side storage part PS and the cathode-side storage part NS of the storage tank 10, and the electrode of the electrolytic element 21 was used. By applying a DC voltage of 6 [V] for 10 minutes, hydrogen bubbles were generated in the stored water in the cathode side storage part NS, but no vibration was applied.

Regarding the amplitude of the vibration, a unimorph type piezoelectric element (C-8 made by Fuji Ceramics Co., Ltd.) immersed in water in the cathode side reservoir NS of the storage tank 10 was applied by the cathode side oscillator 31n. The amplitude voltage V generated in response to the measurement is measured, and the measured amplitude voltage V and the equivalent piezoelectric constant d31 of the piezoelectric element are calculated from the above equation (2). Regarding the vibration intensity, the cathode side vibrator 31n is water. It was calculated from the above-mentioned equation (3) from the frequency of the vibration applied to the above and the amplitude calculated from the above-mentioned equation (2).

For Examples 25 to 32 and Comparative Examples 38 to 48 in which the vibration was applied after hydrogen generation, the state of the produced water before and after the vibration was applied, and in Comparative Example 37 in which the vibration was not applied after the hydrogen generation, the electrolytic element was used. The state of the generated water at the time when the voltage application to the 21 was stopped was visually confirmed, and the state is shown in Table 8. Further, in Examples 25 to 32 and Comparative Examples 38 to 48 in which vibration was applied after hydrogen was generated, vibration was applied after hydrogen was generated 15 minutes after the application of vibration by the cathode side vibrator 31n was stopped. In Comparative Example 37, which was not used, the particle diameter (mode diameter) and the number of fine bubbles contained in the generated water were determined by the nanoparticle analysis system (Nanosite manufactured by Malvern) 15 minutes after the voltage application to the electrolytic element 21 was stopped. The measurement was performed using LM10), and the results are shown in Table 8.

As can be seen from Table 8, Examples 25 to 32 in which the intensity I of the applied vibration by the cathode side vibrator 31n is 8.56×10 ¹² [W/m ² ] or more were cloudy before application of the vibration. The generated water became transparent after the application of vibration, and in 1 ml of the obtained produced water, 6.8 × 10 ⁸ to 9.7 × 10 ⁸ hydrogen fine bubbles having an average cell diameter of about 100 nm were present. I was able to confirm that. Before the vibration is applied, the generated water becomes cloudy because the hydrogen bubble has a large bubble diameter. However, by applying a vibration having an intensity I of 8.56×10 ¹² [W/m ² ] or more to the generated water It is considered that the bubble diameter of the water was reduced to around 100 nm, and the generated water became transparent.

In particular, in Examples 26, 28, 30 and 32 in which the intensity I of the vibration applied by the cathode side vibrator 31n is less than 1.00 × 10 ¹³ [W / m ² ], the cloudy generated water is completely. It took about 30 seconds from the start of application of vibration until it became transparent, but Examples 25 and 27 in which the intensity I of the applied vibration by the cathode side vibrator 31n was 1.00 × 10 ¹³ [W / m ² ] or more. , 29 and 31 become transparent immediately after the application of vibration, and when the intensity I of the applied vibration is set to 1.00 × 10 ¹³ [W / m ² ] or more, the average cell diameter includes about 100 nm. Ozone microbubbles can be generated faster.

On the other hand, in Comparative Example 37 in which no vibration was applied and Comparative Examples 38 to 48 in which the intensity I of the applied vibration was less than 8.56 × 10 ¹² [W / m ² ], the obtained generated water was obtained. Is still cloudy, and it is considered that a large amount of hydrogen bubbles of 3 μm or more are generated. Therefore, the above-mentioned nanoparticle analysis system cannot measure the bubble size and the number of nano-sized fine bubbles.

And the number was measured using a nanoparticle analysis system (Malvern Nanosite LM10), and the results are shown in Table 26.

As can be seen from Table 26, in Examples 77 to 84 in which the intensity I of the applied vibration by the anode-side vibrator 31n was 8.56 × 10 ¹² [W / m ² ] or more, the obtained generated water was transparent. It was confirmed that there were 2.6 × 10 ⁸ to 6.4 × 10 ⁸ hydrogen fine bubbles having an average cell diameter of about 100 nm in 1 ml of the generated water. By applying vibration with an intensity I of 8.56 × 10 ¹² [W / m ² ] or more while generating hydrogen bubbles in running water, the diameter of the generated hydrogen bubbles is reduced to around 100 nm, thereby reducing the diameter of the generated hydrogen bubbles to around 100 nm. It is probable that the generated water became transparent.

On the other hand, in Comparative Example 105 in which no vibration was applied and Comparative Examples 106 to 116 in which the intensity I of the applied vibration was less than 8.56 × 10 ¹² [W / m ² ], the obtained generated water was obtained. Is cloudy, and it is considered that a large amount of oxygen bubbles of 3 μm or more are generated. Therefore, the above-mentioned nanoparticle analysis system cannot measure the bubble size and the number of nano-sized fine bubbles.

With the water filled unit WSU circulating the stored water in the storage tank 10n through the cathode side flowing water channel NC of the flow path forming body 25 for 25 minutes while the water is being filled, the anode 22 is in the anode side flowing water path PC. By applying a DC voltage of 6 [V] between the water and the electrodes (anode 22, cathode 23) of the electrolytic element 21 in which the cathode 23 is in contact with the flowing water in the cathode side flowing water channel NC, the cathode side flowing water channel By generating hydrogen bubbles in the running water in the NC and adjusting the circulation flow rate, the running water in the cathode side flowing water channel NC was turbulent.

While circulating for 25 minutes through the anode side flowing water channel PC of the body 44, a DC voltage of 6 [V] is applied between the electrodes of the electrolytic element 21 to generate hydrogen bubbles in the flowing water inside the cathode side flowing water channel NC. However, the flowing water in the anode side flow channel PC was not turbulent. The bubble generation time is 25 minutes, which is the same as the water circulation time, and the circulation flow rate and the flow velocity in the anode side flow channel PC are as shown in Table 37.

It is considered that by generating hydrogen bubbles in the turbulent flowing water, the bubble diameter of the generated hydrogen bubbles was reduced to about 100 nm, and as a result, the produced water became transparent.

On the other hand, in Comparative Examples 126 to 128 in which bubbles were supplied to the laminar flowing water without turbulence, the obtained generated water became cloudy and a large amount of hydrogen bubbles of 3 μm or more were generated. It is thought that it is. Therefore, the nanoparticle analysis system could not measure the diameter and number of nano-sized fine particles.

Alternatively, since it can be retained in water as hydrogen fine bubbles, as in the conventional case, in order to generate ozone-containing fine bubble-containing water, a fine bubble-containing water generator and an oxygen gas generator can be combined, or oxygen fine bubbles are contained. There is no need to connect an oxygen cylinder or hydrogen bomb to a microbubble-containing water generator in order to generate water or hydrogen microbubble-containing water, and a simple device can inexpensively generate fine bubble-containing water with a bubble diameter of about 100 nm. Can be generated.

In the fine bubble-containing water generators 1 and 2 described above, after generating bubbles in the stored water in the storage tank 10, the strength I of the stored water is 8.56 × 10 ¹² [W / m ² ] or more.

In this way, when vibration having an intensity I of 8.56 × 10 ¹² [W / m ² ] or more is applied while generating bubbles in the stored water, the generated water is less likely to become cloudy, and in particular, the intensity of the applied vibration. When I is set to 1.00 × 10 ¹³ [W / m ² ] or more, the generated water does not become cloudy, so that water containing fine bubbles having a bubble diameter of about 100 nm can be generated more efficiently. ..

Further, in Examples 9 to 32 using the fine bubble-containing water generator 2, vibration is applied to either the stored water of the anode side storage unit PS or the stored water of the cathode side storage unit NS. It is also possible to apply vibration to both the water stored in the anode side storage part PS and the water stored in the cathode side storage part NS, and in that case, the anode side storage part of the storage tank 10 is used.

While hydrogen bubbles are generated in the flowing water in the inside, the anode side vibrator 31p or the cathode side vibrator 31n applies vibration to the flowing water in the anode side flowing water channel PC or the cathode side flowing water channel NC. Not limited to this, electrolysis is performed while simultaneously circulating the stored water in the storage tank 10p and the storage tank 10n through the anode-side flow channel PC of the flow path forming body 44 and the cathode-side flow path NC of the flow path forming body 44. By applying a DC voltage between the electrodes of the element 21, ozone-containing oxygen bubbles or oxygen bubbles are simultaneously generated in the flowing water in the anode-side flowing water channel PC, and hydrogen bubbles are simultaneously generated in the flowing water in the cathode-side flowing water channel NC. It is also possible to simultaneously apply vibration to the flowing water in the anode side flowing water channel PC and the flowing water in the cathode side flowing water channel NC by the anode side vibrator 31p and the cathode side vibrator 31n. In that case, the storage tank 10p Thus, ozone-containing oxygen fine bubble-containing water or oxygen fine bubble-containing water is simultaneously produced in the storage tank 10n.

Further, in Examples 85 to 93 using the fine bubble-containing water generator 7, the water stored in the storage tank 10p or the storage tank 10n is collected from the anode side flow channel PC of the flow path forming body 44 or the cathode of the flow path forming body 44.

While generating hydrogen bubbles in the running water inside, the swirling unit 50 swirls the running water inside the anode-side flowing water passage PC or the cathode-side flowing water passage NC, but the invention is not limited to this, and it is not limited to this. A DC voltage is applied between the electrodes of the electrolytic element 21 while simultaneously circulating the stored water in 10p and the storage tank 10n through the anode-side flow channel PC of the flow path forming body 44 and the cathode-side flow path NC of the flow path forming body 44. By applying, ozone-containing oxygen bubbles or oxygen bubbles are simultaneously generated in the flowing water in the anode side flowing water channel PC, and hydrogen bubbles are simultaneously generated in the flowing water in the cathode side flowing water channel NC, and the flowing water in the anode side flowing water channel PC is generated.

Further, in the above-mentioned fine bubble-containing water generators 3 to 8, vibration is applied to the running water, the running water is vortexed, and the running water is turbulent while generating bubbles in the running water, but the flow is limited to this. Instead, after generating bubbles in the running water by the electrolytic element, vibration may be applied to the running water, the running water may be vortexed or turbulent, and conversely, vibration may be applied to the running water. After applying the vibration, bubbles are generated in the flowing water to which the vibration is applied, or after the flowing water is swirled, the bubbles are generated in the swirled flowing water, or the flowing water is turbulent, and then Bubbles may be generated in the turbulent running water. However, if vibration is applied to the running water after the bubbles are generated in the running water, or the running water is vortexed or turbulent, the bubbles are generated in order to suppress collision between the generated bubbles. Immediately after the generation of, it is necessary to apply vibration to the flowing water, make the flowing water swirl, or make it turbulent.
