BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0016]
FIG. 1 is a diagram showing a first embodiment of the present invention. Reference numeral 1 in FIG. 1 denotes an oxygen-dissolved water conditioner. The oxygen-dissolved water conditioner 1 has a high oxygen partial pressure and is an "oxygen supply means" capable of supplying oxygen 5, and has a very small capacity of 98 cc. And a pressure vessel 3 having a capacity of, for example, 1300 cc and made of a metal plate such as aluminum and stored in a predetermined water level or a full state. By injecting the water 4 into the water 4 toward the water surface 4a and entraining bubbles of oxygen 5 to increase the contact area with the water 4, the water 4 has a high concentration of at least 60 mg / L or more, preferably 100 mg / L or more. It forms water 4 in which oxygen is dissolved. Reference numeral 7 denotes a second pipe having one end connected to the water pump 14, the other end arranged at a position close to the bottom 3 a of the pressure vessel 3, and a strainer 11 formed at the other end.
[0017]
A pressure regulator 8 is connected between the pressure vessel 3 and the oxygen cartridge 2 so that the oxygen pressure can be controlled to a predetermined value, for example, 0.2 Mpa. A first valve 10 that can be opened and closed is interposed between the pressure regulator 8 and the first pipe 6. To the water pump 14 to which the second pipe 7 is connected is connected a third pipe 9 which can flow to the pressure vessel 3 side. The water pump 14 can drain, for example, 1100 cc per minute. In the middle of the third pipe 9, a second valve 12 that can switch between the flow toward the pressure vessel 3 and the flow toward the sixth pipe 13 for drainage is provided. Reference numeral 15 denotes a water supply device, which is connected to a fourth pipe 17 which is connected to the port 3b of the pressure vessel 3, and the fifth pipe 17 is provided with a third valve 16 which can be opened and closed. Become. Reference numeral 20 denotes a fifth pipe disposed on the water surface 4a of the pressure vessel 3, and a fourth valve 19 that can be opened and closed is interposed in the fifth pipe 20. The air can be exhausted and drained from the fourth valve 19. Reference numeral 18 denotes a lid that can open and close the opening 3b of the pressure vessel 3.
[0018]
Therefore, in order to generate the high-oxygen-dissolved water 4 by the oxygen-dissolved water dispenser 1, as a first step, the third and fourth valves 16 and 19 are opened, and the water from the water supply device 15 is supplied through the fourth pipe 17. The water fills the pressure vessel 3 with a predetermined water level or fills. At this time, the air in the pressure vessel 3 is replaced with the water 4 and exhausted and drained through the fifth pipe 20. If the water level is not set to a predetermined level or full, nitrogen in the air is mixed with oxygen and the oxygen partial pressure drops. Therefore, the oxygen 5 and the water 4 are replaced after the water level is set to a predetermined level or full.
[0019]
As the second stage, the third and fourth valves 16 and 19 are closed, the first valve 10 is opened, the second valve 12 is connected to the sixth pipe 13 side, and the water pump 14 is rotated, so that the pressure is increased. The water 4 in the container 3 is sucked from the strainer 11 and drained to the outside via the second pipe 7, the water pump 14, the second valve 12, and the sixth pipe 13. Although the pressure in the pressure vessel 3 is reduced by draining, the oxygen 5 is supplied into the pressure vessel 3 through the first pipe 6, and the oxygen 5 replaced with the water 4 in the upper part of the pressure vessel 3 is retained. About 40 cc is formed.
[0020]
As a third stage, after a lapse of a predetermined time, the water pump 14 is stopped, the first valve 10 is closed, the second valve 12 is switched to open the third pipe 9 side, the third valve 16 is opened, and the water supply equipment 15 is opened. To fill the pressure vessel 3 with water 4 and raise the pressure in the system to about 0.35 Mpa, which balances the pressure with the tap water pressure.
[0021]
As a fourth step, the water 4 in the pressure vessel 3 is sucked up from the strainer 11 of the second pipe 7 by rotating the water pump 14 in anticipation of the time when the pressure is balanced, and the water 4 is supplied to the second pipe 7, Injection is performed by the third pipe 9 toward the water surface 4a in the pressure vessel 3 via the pump 14 and the second valve 12, and the circulation and the fountain of the water 4 are sequentially repeated. When the circulation fountain is repeated at a high pressure and about 3 minutes have passed, water 4 in which oxygen 5 is dissolved in the pressure vessel 3 at a high concentration of 199.5 mg / L or more is generated.
[0022]
The position of the strainer 11 is not limited to being close to the bottom 3a of the pressure vessel 3, and it is sufficient that the strainer 11 is located in the water. If the position of the strainer 11 is close to the bottom 3a of the pressure vessel 3, although the oxygen 5 supplied from the third pipe 9 can be prevented from being sucked into the strainer 11 as it is, the third pipe 9 itself becomes longer and the convenience is inferior. Will be.
[0023]
At the stage when the water 4 in which the oxygen 5 is dissolved at a high concentration of 199.5 mg / L or more is generated in the pressure vessel 3, the water pump 14 is stopped, the first and third valves 10, 16 are closed, and the fourth By opening the valve 19, the pressure of the oxygen 5 in the pressure vessel 3 is reduced by extracting the oxygen 5 to the outside through the fifth pipe 20 and the fourth valve 19. At this time, the decompression is performed stepwise by opening and closing the fourth valve 19 intermittently, and it is possible to prevent the oxygen 5 dissolved in the water 4 in the pressure vessel 3 from dropping out due to rapid decompression. Thereafter, the lid 18 of the pressure vessel 3 is opened, and the water 4 in which the oxygen 5 is dissolved at a high concentration of at least 60 mg / L or more, preferably 100 mg / L or more can be taken out. In the experimental apparatus of the present applicant, 199.5 (mg / L) was confirmed by measurement of dissolved oxygen generated and immediately after release to the atmosphere.
[0024]
FIG. 2 is a diagram showing a second embodiment of the present invention. Reference numeral 30 in FIG. 2 denotes another oxygen-dissolved water conditioner. The oxygen-dissolved water conditioner 30 includes the oxygen cartridge 2 which is an “oxygen supply unit” capable of supplying oxygen 5 and a predetermined water level or full water level. By connecting the pressure vessel 3 stored in a state with the first pipe 6 and bubbling water 4 in the pressure vessel 3 with high partial pressure oxygen 5, the water 4 and the high partial pressure oxygen The contact area with oxygen 5 is increased to produce water 4 in which oxygen is dissolved at a high concentration of at least 60 mg / L or more, desirably 100 mg / L or more. The end of the first pipe 6 on the side of the pressure vessel 3 is near the opening 3b of the pressure vessel 3, and is disposed above the water surface 4a.
[0025]
A pressure regulator 8 is connected between the pressure vessel 3 and the oxygen cartridge 2 so that the oxygen pressure can be controlled to a predetermined value. A first valve 10 that can be opened and closed is interposed between the pressure regulator 8 and the first pipe 6. One end of a second pipe 7 is connected in communication with the first pipe 6, and the other end of the second pipe 7 is connected to the pressure vessel 3 via a check valve 32 to the air pump 31. And extends to a position close to the bottom 3 a of the pressure vessel 3. The other end of the second pipe 7 is provided with a bubble generator 33. Reference numeral 15 denotes a water supply device, which is connected to a fourth pipe 17 which is connected to the port 3b of the pressure vessel 3, and the fifth pipe 17 is provided with a third valve 16 which can be opened and closed. Become. Reference numeral 20 denotes a fifth pipe disposed on the water surface 4a of the pressure vessel 3, and a fourth valve 19 that can be opened and closed is interposed in the fifth pipe 20. The air can be exhausted and drained from the fourth valve 19. Reference numeral 18 denotes a lid that can open and close the opening 3b of the pressure vessel 3.
[0026]
Accordingly, in order to generate the water conditioner 4 in which oxygen is dissolved at a high concentration by the oxygen-dissolved water conditioner 30, as a first step, the third and fourth valves 16 and 19 are opened, and the water supply through the fourth pipe 17 is performed. The inside of the pressure vessel 3 is set to a preset water level or full from the device 15. At this time, the air in the pressure vessel 3 is replaced with the water 4 and exhausted and exhausted through the fifth pipe 20. At this stage, if the water level is not set to the preset water level or full, the nitrogen in the air is mixed with oxygen and the oxygen partial pressure drops. You do it.
[0027]
As a second stage, when the inside of the pressure vessel 3 reaches a preset water level or full, the third valve 16 is closed, the first valve 10 is opened, and the pressure of the oxygen 5 in the oxygen cartridge 2 reduced by the pressure regulator 8 is reduced. The pressure is applied to the inside of the pressure vessel 3 through the first pipe 6, and the water 4 in the pressure vessel 3 is drained from the fifth pipe 20, and a predetermined water level or water 4 in the pressure vessel 3 is set to The replaced oxygen 5 forms a space 21 in the upper part of the pressure vessel 3 where the oxygen 5 stays. When a preset time has elapsed, the first valve 10 and the fifth valve 19 are closed to stop draining.
[0028]
As a third stage, by turning the air pump 24, the oxygen 5 accumulated in the upper space 21 in the pressure vessel 3 is sucked through the first pipe 6, and the bubble generator 33 in the pressure vessel 3 through the second pipe 7. Start publishing by repeatedly discharging into the water. At this time, since the pressure of the oxygen 5 stored in the pressure vessel 3 is a low partial pressure, the air pump 24 can rotate smoothly.
[0029]
As a fourth step, the third valve 16 is opened, and the tap water is introduced into the pressure vessel 3 again from the fourth pipe 17 by the water supply device 15 so that the pressure in the pressure vessel 3 is equal to the pressure of the tap water at about 0.35 MPa. Increase the pressure inside the system.
[0030]
As the fifth stage, the third valve 16 is closed when the pressure in the pressure vessel 3 has equilibrated with the pressure of the tap water, the inflow of the tap water is stopped, and publishing is continued at a high pressure for about 3 minutes. Then, water 4 in which oxygen 5 is dissolved at a high concentration is generated in the pressure vessel 3.
[0031]
When the water 4 in which the oxygen 5 is dissolved at a high concentration is generated in the pressure vessel 3, the air pump 31 is stopped. At this time, when the air pump 31 is stopped, the backflow prevention valve 32 prevents the water 4 in which the oxygen 5 is dissolved at a high concentration in the pressure vessel 3 from flowing back and entering the air pump 31. Thereafter, the fourth valve 19 is opened to reduce the pressure of the oxygen 5 in the pressure vessel 3 through the fifth pipe 20. At this time, by opening and closing the fourth valve 19 intermittently, the pressure is reduced in a stepwise manner, so that the oxygen 5 dissolved in the water 4 in the pressure vessel 3 is less likely to drop out due to the rapid pressure reduction. Thereafter, the lid 18 of the pressure vessel 3 is opened, and the water 4 in which the oxygen 5 is dissolved at a high concentration of at least 60 mg / L or more, desirably 100 mg / L or more can be taken out.
[0032]
At the stage where the first embodiment and the second embodiment are described, the same reference numeral 4 is used for the water 4 as the water before the water preparation, for the tap water, etc., but the meaning is different. Of course, the same reference numerals are used because the figure becomes complicated. The same reference numeral 5 is used for the oxygen 5 in the case where the oxygen is dissolved in the water 4, the oxygen is present only as oxygen, and the oxygen in the stage before the oxygen is dissolved in the water 4. However, since the figure is complicated, the same reference numerals are used.
[0033]
When the pressure vessel 3 is made of a material such as PET resin that can expand and deform when the pressure inside the vessel increases, when pressure is applied to the pressure vessel 3, the pressure vessel 3 itself expands and deforms. This automatically lowers the water level in the pressure vessel 3 without draining and replacing it with the oxygen 5, and an appropriate water level can be obtained.
[0034]
In the above description, the water used as the raw material is described as tap water. However, the prepared water 4 in which oxygen 5 is dissolved at a high concentration using tap water as a raw material has a slightly higher oxidation-reduction potential (ORP) than tap water. Because of the tendency, it has been confirmed that water 4 after alkali ion water preparation is more desirable as a raw material. That is, by using the water 4 after alkali ion water conditioning as a raw material, the water 4 having a higher dissolved oxygen amount, a higher PH, and a lower oxidation-reduction potential (ORP) than tap water can be obtained.
[0035]
In addition, the oxygen cartridge 2 has been described as an example of the oxygen supply means. However, the present invention is not limited to this, and the oxygen supply means may be used as it is in the atmosphere or high-concentration oxygen of an oxygen concentrator may be used.
[0036]
