Description

  The present invention relates to a method and an apparatus for generating negative air ions, and more particularly to a method for generating a large amount of negative air ions by ionized fog using water and an apparatus used for the method.

Although the ratio of negative ions to positive ions in the atmosphere is said to be about the same, the number of positive ions has increased in recent years as the environment has changed, and the ion balance in the atmosphere has been disrupted. To avoid this harmful effect, put yourself in a balanced environment of negative ions and positive ions, such as fatigue recovery effect, blood purification effect, mental stability effect, resistance enhancement effect, autonomic nerve adjustment effect, etc. It is widely known that a medical effect can be obtained.
Based on these findings, various methods for artificially increasing the concentration of negative ions have been proposed. These are broadly divided into those using high-pressure corona discharge, those using ultraviolet rays, those using radiation, and water. It is classified into things to use. The present invention belongs to a method for increasing the concentration of negative ions using water.

  In Patent Document 1, in the processing chamber 1 through which the air to be processed should pass, water is collided with the rotating bodies 12A and 12B having the meshes and scattered, thereby generating a water curtain by mist and passing through the processing chamber. There has been proposed an anion generation method and apparatus for increasing the concentration of anions in the air to be treated by contacting the water curtain. This method has a large contact area between water and air, and is an effective method for splitting water. However, suspended dust in which water in the reservoir is contained in the air due to the contact reaction between water and air. There is a problem that gets dirty.

  In Patent Document 2, the housing 1 has a nozzle 10 in the square tube 14 as the water splitting portion 2. External air is forcibly press-fitted into the square tube 14 and flows while turning inside the square tube 14. The nozzle 10 ejects water toward the inner wall of the rectangular tube 14 during the swirling flow of air. Since air swirls within the rectangular tube 14, vortices are generated at the corners of the rectangular tube 14 and flow as a swirl flow with turbulent flow as a whole, and the jet water is effectively involved in the turbulent flow and fine water droplets. A negative ion generator that generates a large amount of negative ions in the air has been proposed. This method also has a large contact area between water and air, and is an effective method for splitting water. However, because of the contact reaction between water and air, the water in the reservoir is contained in the air. There is a problem that gets dirty.

  Patent Document 3 discloses a cabinet 21 and a water spray rotator 41 that is provided inside the cabinet 21 and receives water supply and scatters the water toward the inner wall of the first vertical partition plate 27 by centrifugal force. And a fin-shaped protruding wall 14 provided along the inner wall of the first vertical partition plate 27 so as to face the tangential direction of the water spray rotator 41, and is ejected from the tangential direction of the water spray rotator 41. Compared with the case where the water collides with the fin-type protruding wall 14 at a right angle and collides with the water along the inner wall of the first vertical partition wall 27, Liquid refining devices, air purifiers, negative ion generators, and humidifiers that can reduce water flowing in the direction have been proposed. This method also has a large contact area between water and air, and is an effective method for splitting water. However, because of the contact reaction between water and air, the water in the reservoir is contained in the air. There is a problem that gets dirty.

  In Patent Document 4, there is a soot firing means B for firing weathered soot powder, there is a soot ceramic cartridge 1 and a desorption water container 2 for containing water, and the soot ceramic 1a formed by the soot firing means is supplied from the water inlet 3. The water W is reacted with water, and the water W is alkali ionized. Further, there is an ultrasonic oscillator 6 that applies vibration force to the alkaline ionized water produced by reacting the soot ceramic 1a with the water W in the desorption water container 2 described above. Finally, a functional bioactive negative ion air generator using ceramic vibration force utilizing ceramics, in which the fan 7 applies wind force to the negative ion air A emitted by the ultrasonic oscillator 6 has been proposed. This method uses an ultrasonic vibrator in the atomizing section, and can select the size of the generated mist while separating the mist directly from the water, so that the water in the water storage section is less likely to be contaminated by floating dust contained in the air, Although it is an excellent method capable of separating the generated mist from the inside and the inside, there is a problem that the generation of negative ion air is suppressed by the step of alkali ionizing water.

  In patent document 5, while providing the ventilation part 7 and the atomization part 8 in the inside of the container 1 which provided the foot insertion part 2, the mist channel | path leading to the blower outlet 18 which faces the foot insertion part 2 from this atomization part 8 In the vicinity of the air outlet in 19, an ionization portion 21 that charges mist by discharge is provided. When the atomizing unit 8 is operated by putting the foot into the foot putting unit 2, the water W in the atomizing unit 8 is atomized to become mist, and is negatively ionized by the ionizing unit 21 through the mist passage 19 and is discharged from the outlet 18. There has been proposed a mist spraying device that is blown into the foot insert 2 and fills the foot insert 2. This method uses an ultrasonic vibrator in the atomizing part and separates the mist directly from the water, so it is an excellent method that the water in the water storage part is less likely to be contaminated by airborne dust contained in the air. Since the separation step is not included, there is a problem in that all mist including large, medium and small mist generated is discharged. There is also a problem that an ionization part needs to be provided because the amount of ions generated from the atomization part is small.

  In Patent Document 6, a rotating body 1 is disposed so that an upper part is surrounded by a sirocco fan 2 and a lower part protrudes from a fan casing 3 and is immersed in water 5 stored in a lower part of a housing 4. 1 and the sirocco fan 2 are rotated in conjunction with each other by power, the water is pumped by the rotating body 1 and projected and pulverized onto the sirocco fan 2, and the generated water droplets are reprojected and pulverized onto the fan casing 3 by the sirocco fan 2. Negative ion generators that increase the generation volume have been proposed. This method also has a large contact area between water and air, and is an effective method for splitting water. However, because of the contact reaction between water and air, the water in the reservoir is contained in the air. There is a problem that gets dirty.

  In Patent Document 7, in the processing chamber 1 into which outside air can be introduced, the lower part of the rotating body 3 whose diameter increases upward is immersed in water and rotated, so that the water along the outer periphery of the rotating body. The thin film is sequentially formed and scattered upward, and the scattered water collides with a screen having a mesh 4 through which water and air arranged around the rotating body can pass. In addition, there has been proposed an anion generator that uses the inner wall of the eye to increase the collision frequency of water to form a mist atmosphere containing anions. This method also has a large contact area between water and air, and is an effective method for splitting water. However, because of the contact reaction between water and air, the water in the reservoir is contained in the air. There is a problem that gets dirty.

  Patent Document 8 includes a water tank 3, a mist outlet 4, a blower fan 5, and an ultrasonic transducer 6 attached to the water tank 3. A driving frequency of the ultrasonic transducer 6 is set to 2 to 4.7 MHz, and a negative ion generating method and a negative ion generating device for generating negative ions at the same time as generating mist in the air inside the water tank 3 are proposed. ing. This method also uses an ultrasonic vibrator in the atomizing part and separates the mist directly from the water, so it is an excellent method that the water in the water storage part is less likely to be contaminated by airborne dust contained in the air. Since the separation step is not included, there is a problem in that all mist including large, medium and small mist generated is discharged.

  In Patent Document 9, (1) in an air ion generation method in which water is atomized and ionized mist is supplied into the air, at the time of causing the mist to collide with a collision wall to generate a flow of ionized mist, An air ion generation method in which Mizuku Electric Dipole Crystal Mineral is present on the surface or ionization mist flow path to increase the number of ions, (2) In an air ion generator that atomizes water and supplies ionized mist into the air, The water in the basin container is atomized by using an atomizer and supplied into the air, the mist supplied in the air collides with the collision wall to generate a flow of ionized fog, and at least the collision wall Air ion generation method, generator and set are proposed, which is an air ion generator having a configuration in which the number of ions is increased by the presence of Mizuku Electric Dipole crystal mineral on the surface or ionization fog channel That. This method also uses an ultrasonic vibrator in the atomization part and separates the mist directly from the water, but this method also has a contact area between water and air due to the presence of collision walls and Mizuhisa's electric dipole crystal mineral. In many cases, the water in the reservoir is contaminated by airborne dust contained in the air.

  In Patent Document 10, the raw liquid is atomized and evaporated by ultrasonic waves generated from an ultrasonic vibrator, thereby generating pseudo smoke and pseudo incense that are the same as smoke and scent generated during cooking. In an ultrasonic atomizer that spouts the liquid on the cooking table, an inverted conical trap for suspending the liquid column generated by the ultrasonic vibrator is suspended, and an air intake is provided on one side of the liquid bowl. On the other side, there has been proposed an ultrasonic atomizing device for use in a sales device for foods or the like with a pseudo effect, characterized in that a gas spout opening on a cooking table is provided. Although it is used for a different purpose, it is a small and flat device, and it is an excellent method that the mist is fine.However, because the air intake is located under the trap due to structural problems, the water in the reservoir is turned into air. The problem of fouling with the airborne dust contained remains unresolved.

  In Patent Document 11, supply water that has been activated in advance is atomized, and this is brought into contact with a rotating body with pores and scattered by centrifugal force to collide with a ceramic plate for water activation arranged around the rotating body. After that, a negative ion generation method and apparatus have been proposed in which negative ions are generated by discharging only fine mist to the surrounding environment except for a relatively large size mist. Although this method is an excellent method in that the released mist is fine, there is a problem that the water in the water storage section is contaminated by the suspended dust contained in the air because the water in the water storage section is circulated and used.

These conventional ion generation methods using water as a medium do not generate ozone, which is a problem of using high-pressure corona discharge, but overcome the problem of ion generation, which is a problem of using ultraviolet rays, and problems of using radiation. Although it is an excellent method that can solve the problem of exposure, it has individual problems as described above.
However, it is not focused on the generation of negative ions for the supplied water, the amount of generated air negative ions is limited, and a device with a complicated structure is required to generate air negative ions. The problem remains.

JP-A-9-203540 JP-A-10-160211 Japanese Patent Laid-Open No. 11-19537 JP 2000-227239 A JP 2002-143267 A JP 2002-195615 A JP 2002-349919 A JP 2003-322369 A JP 2004-154461 A JP-A-2005-106906 JP 2006-180895 A

  Accordingly, an object of the present invention is to provide a method and an apparatus for easily generating air negative ions simultaneously with atomization while solving the problem that the water in the water storage section is contaminated by suspended dust contained in the air.

  In order to achieve the above object, the method for generating negative air ions with water according to claim 1 is characterized in that, in the step of generating a large amount of negative air ions by fine mist using water, the water to be used is purified and water is used. The electrical conductivity is regulated to 10 μS / cm or less so that the charging energy of water can be easily extracted.

  This invention is based on the result of paying attention to the electric resistivity (electric conductivity) of water, and in the case of ordinary tap water, the resistivity is about 4,000 Ω · cm to 5,000 Ω · cm (100 μS / cm). On the other hand, in the case of ultrapure water, the resistivity becomes approximately 10 MΩ · cm to 18 MΩ · cm (0.1 μS / cm) and approaches the insulator. Even if the water in this state is flowed, an electrostatic phenomenon occurs in the water, the water is negatively charged, and the nearby resin container is positively charged.

  Furthermore, when burst (explosion / explosion / crushing) energy or water (cavity) energy is added to refine water, it induces an accumulative additional charging phenomenon depending on the type and strength. At the same time, a large amount of negative air ions are generated. In the apparatus of the present invention, the cavity energy is used, but the apparatus using the burst energy can be realized and is not limited to the apparatus, and can be applied to all methods of generating negative air ions using water.

  The apparatus for generating negative air ions according to claim 2 includes a step of supplying water, a step of generating violent vibration by locally generating vibration by vibration from an ultrasonic transducer, and a fine amount of fog generated. In an air negative ion generator comprising a step of separating mist and a step of discharging separated fine mist, the supplied water is purified to restrict the electric conductivity to 10 μS / cm or less, and a large amount of air negative ions It is characterized by generating.

  In order to realize generation of a large amount of negative air ions with a simple mechanism for generating mist by an ultrasonic vibrator, the present invention purifies the supplied water and regulates the electric conductivity to 10 μS / cm or less. This creates a situation where water tends to be negatively charged. The electric conductivity of the supplied water tends to increase the amount of negative air ions as it decreases, but it peaks at about 0.05 μS / cm, and then becomes tapered. If economical efficiency is calculated | required, it will be about 5 micro S / cm-10 micro S / cm, and if it pursues performance, it will be 1 micro S / cm or less.

  The negative air ion generator with water according to claim 3, wherein in the step of separating the fine mist from the generated mist, an inverted conical cylinder surrounding a water column that is expressed by vibration from an ultrasonic vibrator is provided. A water return is provided, an infinite number of holes are provided at the top of the water return part, and an air intake for guiding fine mist that has passed through the hole is provided above the top of the water return part at the bottom of the inverted conical cylinder. It is characterized by that.

  This invention is for solving the problem that the water in the water storage section is contaminated by the suspended dust contained in the air, and the liquid droplets are separated and scattered from the water column generated by the cavity energy of the ultrasonic vibrator. Large droplets return to the water because they are heavy when they hit the inner wall of the inverted conical cylinder, but small droplets are light even if they collide with the inner wall of the inverted conical cylinder, so they enter the space between the inner wall and water. Drift and fill. Since the internal pressure slightly increases with the fullness, only the fine mist with the smallest diameter passes through the return of water to the lower part of the inverted conical cylinder and further passes through the hole at the apex. However, since the absolute amount of the fine mist that has passed through is insufficient, an air intake that guides the fine mist that has passed through the hole is provided above the top of the water return part at the bottom of the inverted conical cylinder. Therefore, the amount of necessary fine mist can be adjusted by the amount of air flowing into the air intake.

  In addition, by providing a water return at the bottom of the inverted conical cylinder, it is possible to select only a fine mist from medium and small droplets. This fine mist is a very small particle that does not get wet even if it is attached to the hand, and since it is released to the outside together with the air induced from the air intake, it can eliminate the problem of contaminating the water in the reservoir due to the introduced air. is there.

  As described above, according to the invention of claim 1, the water to be used is purified and the electric conductivity of the water is regulated to 10 μS / cm or less, thereby creating a situation where the water is easily charged negatively. Air negative ions can be generated with higher efficiency than the conventional generation method.

  According to the invention of claim 2, by controlling the electric conductivity of the simple mechanism for generating mist by the ultrasonic vibrator and the supplied water to 10 μS / cm or less, the air can be produced with higher efficiency than the conventional generator. Negative ions can be generated.

  According to the invention of claim 3, the inverted conical cylinder of the droplet separation mechanism and the return of the lower water produce a fine mist of extremely small particles that do not wet even when attached to the hand, and by the introduced air The problem of dirty water in the reservoir can be solved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. FIG. 1 is a cross-sectional view showing the structure of the present invention, which includes a container 1, an ultrasonic vibrator 2, a transmission circuit 3 connected to the ultrasonic vibrator 2, and a mist separation mechanism 4. FIG. 2 is a cross-sectional view of the mist separation mechanism 4. The container 1 is provided with an ultrasonic vibrator 2, an air intake 5, an air negative ion discharge port 6, and a purified water supply port 7.

  When power is supplied from the transmission circuit 3 to the ultrasonic vibrator 2, the purified water 8 generates a substantially conical liquid column 9 by vibration energy. The liquid column 9 generates various droplets of various sizes by vibration. When a large droplet hits the inner wall of the inverted cone tube of the mist separation mechanism 4, its weight is returned to the water because it is heavy, and a small droplet is light even if it hits the inner wall of the inverted cone tube. The space 10 is filled with drifting. Since the internal pressure slightly increases with the fullness, only the fine mist with the smallest diameter flows in the direction of the arrow 11 and passes through the water return portion 12 at the bottom of the inverted conical cylinder of the mist separation mechanism 4 of FIG. , It passes through the hole 13 at the apex.

  The source of the negative ionization mist uses pure water 8 that has been purified to produce a situation in which water tends to be negatively charged by regulating the electrical conductivity to 10 μS / cm or less. Therefore, the fine mist generated through the water return portion 12 at the bottom of the inverted conical cylinder of the mist separation mechanism 4 of FIG. 2 and generated from the hole 13 at the apex contains a large amount of negatively charged ions.

  The fine mist that drifts and fills the space 10 between the inner wall of the inverted conical cylinder of the mist separating mechanism 4 and the water and passes through the hole 13 at the apex is guided by the air flow 14 fed from the air intake 5, The mixture is stirred and mixed in the space 15 between the mist separation mechanism 4 and the container 1, and is discharged from the container 1 as air negative ions 16. The amount of air negative ions 16 required is adjusted by the amount of air flow 14 flowing into the air intake 5.

  Using the air negative ion generator of the present invention, air is supplied to the air intake 5 at about 4 liters / min, the electric conductivity of the supplied water is changed, and the air negative ions 16 of the air negative ion discharge port 6 are changed. As a result of measuring a numerical value (manufactured by Andes Electric Co., Ltd., air ion counter ITC201A), the following measured value was obtained.

  When the electric conductivity of the supplied water is adjusted to 40 μS / cm, the numerical value of the air negative ions 16 in the air negative ion discharge port 6 is 325.000 / cc on average (the positive ion is 211.000 on average) Pcs / cc).

  When the electric conductivity of the supplied water is adjusted to 30 μS / cm, the value of the air negative ions 16 of the air negative ion discharge port 6 is 497.7000 / cc on average (the value of positive ions is 272.000 on average). Pcs / cc).

  When the electric conductivity of the supplied water is adjusted to 20 μS / cm, the number of air negative ions 16 in the air negative ion discharge port 6 is 566.6000 / cc on average (the number of positive ions is 298.000 on average) Pcs / cc).

  When the electric conductivity of the supplied water is adjusted to 10 μS / cm, the number of air negative ions 16 in the air negative ion discharge port 6 is 679.000 / cc on average (the number of positive ions is 357,000 on average) Pcs / cc).

  When the electric conductivity of the supplied water is adjusted to 5 μS / cm, the numerical value of the air negative ions 16 of the air negative ion discharge port 6 overflows (1300.000 or more) and cannot be measured (the positive ion value is , Averaged 438.000 pieces / cc).

  According to the measurement results, it can be seen that the numerical value of the air negative ions 16 greatly increases as the electrical conductivity decreases, and a large amount of air negative ions are generated. And it became clear that the ratio of a negative ion and a positive ion was also improved, and the effect of the present invention was acquired.

It is sectional drawing which shows the structure of this invention. It is sectional drawing of the mist separation mechanism of this invention.
