It is a figure which shows preferable embodiment of the electrolytic microbubble water generator for drinks of this invention. It is sectional drawing which shows the structural example of the aspirator shown in FIG. It is a figure which shows the process until a micro bubble disappears. It is a figure which shows the example of a correlation with the time transition of the number of remaining microbubbles, and a particle size distribution. It is a figure which shows another embodiment of this invention.

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

  FIG. 1 shows a preferred embodiment of the electrolytic microbubble water generator for beverages of the present invention.

  The beverage electrolytic microbubble water generator 10 shown in FIG. 1 includes an electrolytic ionic water generator 11 and a microbubble generator 20. The microbubble generator 20 is an aspirator as an example.

  The electrolytic ionic water generator 11 is a commercially available device that passes water L to generate “delicious water”, and the water L is, for example, water pumped up from the underground or tap water. In the electrolytic ion water generator 11, when a direct current is applied to the anode and the cathode and a direct current is passed through the water, the positive ions are attracted to the cathode and the negative ions are attracted to the anode. Further, water in contact with the surface of the electrode is electrolyzed, hydroxide ions (OH-), cations and dissolved hydrogen (H2) are increased on the cathode side, and alkali ion water is generated, and hydrogen is generated on the anode side. The amount of ions (H +), anions, dissolved oxygen (O2), etc. increases, and acidic water is generated.

  As shown in FIG. 1, the inlet 12 of the electrolytic ionic water generator 11 is detachably connected to a faucet 13 for supplying tap water, for example, directly or via a pipe 14. The outlet portion 15 of the electrolytic ion water generator 11 is detachably connected to the inlet portion 19 of the microbubble generator 20 directly or via a pipe 22.

  The microbubble generator 20 shown in FIG. 1 is an apparatus for further smoothing the taste of “delicious water” obtained by passing water L such as tap water through the electrolytic ion water generator 11.

  FIG. 2 is a cross-sectional view showing a structural example of the microbubble generator 20 shown in FIG.

  As shown in FIG. 2, the microbubble generator 20 is a cylindrical member made of, for example, metal, plastic, or the like, and is included by mixing the microbubbles with the water L through the water L. It can be used as a microbubble generator. The microbubble generator 20 has a first cylindrical portion 21 and a second cylindrical portion 22, and the first cylindrical portion 21 and the second cylindrical portion 22 are continuously connected in series along the axial direction CL. Is formed.

  As shown in FIG. 2, the first cylindrical portion 21 has a water passage portion 23 inside, and a tapered member 24 is fixed to the water passage portion 23. The taper member 24 is formed to be tapered so as to become gradually smaller along the water flow direction T. The taper member 24 has a water outlet 26, and a member 25 that forms a swirling flow of water along the central axis CL is fixed in the taper member 24. An inner diameter D1 of the water outlet 26 of the tapered member 24 is set smaller than an inner diameter D2 of the inlet portion 19 of the first tubular member 21.

  As shown in FIG. 2, the second cylindrical member 22 has a water inlet 27 and an outlet portion 28, and the inner diameter of the second cylindrical member 22 is the water inlet 27 and outlet portion. It gradually increases along the water flow direction T toward 28. The inner diameter D3 of the smallest water inlet 27 of the second cylindrical member 22 is the same as the inner diameter D1 of the water outlet 26 of the tapered member 24, and the inner diameter of the largest outlet portion 28 of the second cylindrical member 22 is. D4 is set larger than the inner diameter D3 of the second cylindrical member 22.

  As a result, as shown in FIG. 1, the water L that has exited from the outlet portion 15 of the electrolytic ionic water generator 11 enters the inlet portion 19 of the first cylindrical portion 21 of the microbubble generator 20 in the water flow direction T. When flowing in, the water L turns into a swirl flow by passing through the member 25 that forms a swirl flow of water. The center of the swirling flow of the water L is in a vacuum state, and the air dissolved in the water L and the inflowed air become microbubbles and pass through the water outlet 26 and the water inlet 27 of the tapered member 24. Thus, a large number of microbubbles H are mixed with the water L. In this case, the microbubble generator 20 connected to the electrolytic ionic water generator 11 can generate a microbubble in the electrolytic ionic water by decompressing the electrolytic ionic water and releasing the pressure. Accordingly, the water L containing a large number of microbubbles H can be discharged from the outlet portion 28 to, for example, the cup 30.

  Next, a method for generating electrolytic microbubble water for beverages using the above-described electrolytic microbubble water generator for beverages 10 will be described with reference to FIGS. 1 and 2.

  When the user opens the faucet 13 shown in FIG. 1 and supplies water L to the inlet portion 12 of the electrolytic ionic water generator 11 through the pipe 14, the water L is electrolyzed and is generated in the electrolytic ionic water generator 11. “Delicious water” is produced.

  Next, the water L, which is “delicious water” that has exited from the outlet portion 15 of the electrolytic ion water generator 11, enters the inlet portion 19 of the first cylindrical portion 21 of the microbubble generator 20 in the subsequent stage shown in FIG. When the water L flows in along the flow direction T of the water, the water L, which is “delicious water”, passes through the member 25 that forms the swirling flow of water, and turns into a swirling flow. Thus, the pressure is released toward the outlet portion 28 through the water outlet 26 and the water inlet 27 of the taper member 24, and a large number of microbubbles H are mixed with the water L. For this reason, the water L containing microbubbles can be discharged from the outlet portion 28 to, for example, the cup 30.

  Thereby, the water L, which is “delicious water” generated by the electrolytic ion water generator 11, can be further mellowed by passing through the microbubble generator 20. The microbubbles H generated by the microbubble generator 20 are preferably microbubbles or nanobubbles, and the microbubbles H have an electrolyte around them, and this electrolyte becomes a core of ions and is long in tap water. Studies have shown that time can exist. For example, since microbubbles H have a property of increasing permeability by including microbubbles such as microbubbles in the water L, the water L containing microbubbles is comfortable over the throat when swallowed.

  Water containing microbubbles, such as microbubbles, micronanobubbles and nanobubbles, obtained with the electrolytic microbubble water generator 10 for beverages, for example, when used in a tea pack, improves the dissolution of black tea, Experiments have shown that cooking rice makes the rice taste much better. Water containing microbubbles such as alkaline ionized water and microbubbles is highly effective for beverages, and water containing microbubbles such as acidic ionized water and microbubbles is effective for treating skin diseases such as atopy.

  FIG. 3 (A) shows the process until the microbubbles H disappear. The microbubbles H having a low pressure inside are trying to reduce the surface area, the pressure inside becomes high, and the gas inside the microbubbles H is shown. Dissolves in water. The reason why the internal gas is dissolved in water is that the solubility of this gas is proportional to the pressure (Henry's law). Then, the particle diameter of the microbubbles H becomes smaller and disappears in an attempt to maintain the pressure inside the microbubbles H.

  As described above, the microbubbles H usually disappear in a short time, but in order to solve the disadvantage that the microbubbles H have a short life, an electrolyte is mixed so that the electric conductivity in the aqueous solution is 300 μS / cm or more. By doing so, the short life of the microbubbles H can be solved.

  As shown in FIG. 3B, the inside of the microbubble H has a negative potential and the outside has a positive potential. Although the shrinking force G is applied to the microbubbles H, an electrostatic repulsive force K acts between ions of the same sign existing on the opposite surface of the microbubbles H by mixing the electrolyte. When the particle size of the microbubbles H is 500 nm or less, the shrinking force G and the electrostatic repulsive force K are balanced, so that the particle size of the microbubbles H is not easily reduced, and the life of the microparticles can be extended.

  As described above, according to the embodiment of the present invention, ions that have been electrolyzed by an electrolytic ion generator and have been properly potential-separated are used as nuclei to protect the disappearance of microbubbles, such as nanobubbles, and lengthen microbubbles in water. There is an effect to hold for a period.

  FIG. 4 shows, as an example, a correlation between the time transition of the number of microbubbles (nanobubbles) remaining in water and the particle size distribution.

  In FIG. 4, for nanobubbles that are examples of microbubbles, the total number of microbubbles having a particle size of 100 to 200 nm, the total number of microbubbles having a particle size of 200 to 300 nm, and the total number of microbubbles having a particle size of 300 to 400 nm. And the total number of microbubbles having a particle size of 400 to 500 nm. In FIG. 4, the particle size distribution of the microbubbles is divided every 100 nm, and the transition of the remaining number of elapsed days is graphed.

  According to FIG. 4, the microbubbles of any particle size protect the fine particles by suppressing the disappearance of the fine particles with the ions separated by the potential by electrolysis as the nucleus. It can be seen that the number of days is at least 2 weeks to 3 weeks, but it is slightly decreased, but is almost maintained, and microbubbles remain in water even after 3 weeks. For this reason, about the water containing the microbubble of the particle size shown in FIG.

  On the other hand, in the case where the microbubbles remaining in the water as in the prior art do not contain ions that have been electrolyzed and separated by electric potential as nuclei, the microbubbles are microscopic when 3 hours or more have passed after the microbubbles are generated. The bubbles disappear, and the concentration of the microbubbles decreases in such a short time that the number of microbubbles cannot be measured.

  FIG. 5 shows another embodiment of the present invention.

  FIG. 5 shows another structure example of the microbubble generator. The structure of the microbubble generator 20B is substantially the same as the structure of the microbubble generator 20 shown in FIG. The difference is that a valve 40 is provided. The introduced air amount adjustment valve 40 includes an intake pipe 41 and a sphere 42 disposed in the intake pipe 41. By moving the spherical body 42 in the intake pipe 41, air is introduced or stopped, and the amount of introduced air is optimized according to the amount of tap water flowing into the microbubble generator 20B. Can be adjusted.
