(Embodiment 1)
The ion generator of Embodiment 1 of this invention is demonstrated with reference to FIGS. 1A is a plan view of an ion generator according to Embodiment 1 of the present invention, FIG. 1B is a side view of the ion generator, and FIG. 1C is a bottom view of the ion generator. . First, the ion generator 1 is covered with a housing 2, and the housing 2 is provided with an attachment portion 5 of an ion emission cylinder 4 of an air gun 3, and a positive discharge is provided at the center of the discharge space portion 6 at the center thereof. An electrode 7 and a negative discharge electrode 8 are provided. A connector 9 for connecting a power source is provided on the bottom surface side of the ion generator 1.

  Next, the basic internal configuration of the ion generator 1 will be described with reference to FIG. 2A is a side view of the control unit of the ion generator of Embodiment 1, FIG. 2B is a side cross-sectional structure diagram of the ion generator, and FIG. 2C is an enlarged cross-sectional view of the ion emitter. (D) is an IID-IID line enlarged sectional view in (B). In FIG. 2, the ion generator 1 includes an ion generator 10, an ion emitter 11, and a high-voltage power supply 12 that applies a high voltage for generating ions to the ion generator 11. The ion emission unit 11 includes an ion emission cylinder 4 surrounding the ion generation unit 10, an air cannon 3, and a driving unit 16 for the air cannon 3. The air cannon 3 instantaneously increases the atmospheric pressure in the ion emission cylinder 4 and releases ions generated in the ion generation part 10 from the opening 14 provided in the ion emission cylinder 4 at a stretch.

  The ion generator 1 in this Embodiment is provided with the control part 17, and is controlled by this control part 17 as follows. One air vortex by the air cannon 3 can contain both positive ions and negative ions, or one air vortex by the air cannon 3 can contain only positive ions or negative ions. In addition, the type of generated ions, that is, positive and negative ions, only positive ions, or only negative ions, and the timing of ion generation can be made variable. Furthermore, the drive timing of the air cannon 3 and the timing for switching the type of ions to be generated can be linked.

  A power source is connected to the control unit 17 and the high voltage power source 12 by a connector 9. It is conceivable that this power source is supplied directly from a power source or from a battery. The control unit 17 is supported by the substrate holding unit 2 a of the housing 2, and the discharge electrodes (the positive discharge electrode 7 and the negative discharge electrode 8) protrude from the inside of the housing 2 through the housing 2. The control unit 17 includes a circuit for generating a drive waveform of an ion generation element (not shown) of the ion generation unit 10, and includes a booster coil 19, a switching element 20, a connector 9 for connecting a power source on the substrate 18, Other necessary electronic components 21 (only some of them are displayed) are mounted.

  The booster coil 19 houses the booster coil 19b (primary and secondary) inside the cover 19a, and is connected to the substrate 18 by a terminal 19c for connecting a power source (FIG. 2D). The air gun holding part 5 of the housing 2 is fixed by attaching the ion emission cylinder 4, and the positive discharge electrode 7 and the negative discharge electrode 8 pass through the housing 2 at the discharge electrode holding part 2 b to the substrate 18 of the control part 17. It is connected. In the first embodiment, the discharge electrode itself is connected to the substrate 18, but the discharge electrodes 7, 8 and the control unit 17 may be connected by another conductive material. The inside of the housing 2 is filled with the filling resin 23 up to a position 22 slightly above the upper surface of the substrate 18.

  Next, the details of the ion emission part 11 will be described with reference to FIG. Inside the ion emission cylinder 4 of the air cannon 3, a partition plate 24 for pumping air is disposed inscribed so as to cover almost the entire cross section of the ion emission cylinder 4, supported by a spring 25, and a magnetic body 26. Is pressed against the housing 2. The positive discharge electrode 7 and the negative discharge electrode 8 penetrate the partition plate 24 through holes 27 formed in the partition plate 24. The spring 25 is guided by a spring guide 28 provided on the ion emission cylinder 4 and a spring guide 29 provided on the partition plate 24. A magnetic body 26 is fixed to the partition plate 24, and the magnetic body 26 is disposed at the center of the electromagnetic coil 30 so as to be movable. By energizing the electromagnetic coil 30 from the control unit 17, a repulsive force acts on the electromagnetic coil 30 and the magnetic body 26, and the magnetic body 26 and the partition plate 24 are pushed out in the arrow X direction, and the spring 25 is compressed. . By energizing the electromagnetic coil 30, the partition plate 24 is pushed out toward the opening 14 at the tip of the gun barrel 4, whereby the air of the ion generator 10 can be pushed out.

  Next, FIG. 3 is a partial cross-sectional view of ion generator 10 and ion emitter 11 of ion generator 1 according to Embodiment 1, in which ions are generated by corona discharge from positive discharge electrode 7 and negative discharge electrode 8. Is generated in the ion generator 10. The discharge electrodes 7 and 8 are needle-shaped electrodes with sharp tips. The positive discharge electrode 7 is connected to the positive high voltage circuit of the high voltage power source 12, and the negative discharge electrode 8 is connected to the negative high voltage circuit of the high voltage power source 12. Normally, positive and negative high voltage are alternately applied, and positive, The controller 17 controls the negative ions so that they are alternately emitted. Both ions are emitted toward the external space from the opening 14 provided in the ion emission cylinder 4 while attracting each other. In this case, the distance that ions reach from the opening 14 provided in the ion emission cylinder 4 is about 50 cm to 1 m (the portion illustrated by the broken line ellipse 31). Since the positive and negative high voltage outputs are individually controlled by the control unit 17, the positive or negative high voltage output can be controlled independently, so that only the positive high voltage output or only the negative high voltage output can be output. Is possible. That is, the control unit is configured to separately control the release of positive and negative ions as necessary.

  Next, the controller 17 that controls ion generation will be described with reference to FIG. FIG. 4 is a block diagram of the configuration of the control unit 17 of the ion generator 1 according to the first embodiment. First, power is supplied from the power input unit 32, and the drive circuit unit 33 operates. The drive circuit unit 33 includes an oscillation circuit unit (not shown) for ON / OFF of ion generation and high voltage generation. In response to the oscillation signal from the drive circuit unit 33, an AC high voltage is generated by the high voltage generation circuit unit 34 (comprising the booster coil 19 and the like). The positive and negative voltages are selected by the positive high voltage control unit 35 and the negative high voltage control unit 36, and the high voltage is output to the discharge electrode via the positive high voltage output unit 37 and the negative high voltage output unit 38, respectively. By turning ON / OFF the positive and negative outputs by the high voltage control units 35 and 36, the release of positive ions and negative ions can be controlled.

  Next, the state of ion emission by the air cannon 3 will be described with reference to FIG. In the figure, FIGS. 5A to 5D sequentially show time-series changes. First, FIG. 5A is a diagram at the beginning of the generation of ions, and positive ions, negative ions, or both ions are generated from the positive discharge electrode 7 and the negative discharge electrode 8 as necessary. Next, in FIG. 5 (B), the electromagnetic coil 16 is energized, the partition plate 24 is pushed out, and the air of the ion generating part 10 is pushed out. Then, the pushed air generates a rotating airflow in the direction of the arrow X in the vicinity of the opening 14 of the air cannon 3, and one ring-shaped air vortex 39 is formed, and the air vortex 39 rotates while maintaining the ring shape. Fly away. Since the ions fly while being confined in the air vortex 39, the ions are sent to the place where the air vortex 39 reaches. Next, in FIG. 5C, the energization to the electromagnetic coil 16 is turned off and the partition plate 24 is pushed back by the spring 25. At this time, the first air vortex 39 is flying a little earlier. Next, in FIG. 5D, the electromagnetic coil 16 is energized, and the next air vortex 40 is pushed out and jumps out in the same manner as in FIG. 5B. As described above, the air vortices 39 and 40 containing ions can be continuously blown, and the reach distance of the air vortices 39 and 40 is determined by the performance of the air cannon 3 but is pushed out by the air cannon 3. By appropriately setting the air volume and speed, the size of the air vortices 39, 40, etc., it is possible to fly up to a distance of several meters, and the ion reach distance is considerably larger than the distance of emitting ions with only the ion wind. Can be stretched. Needless to say, in the present embodiment, an operation mode using only ion wind is also selectable.

  Next, another operation example in this embodiment will be described with reference to FIG. FIG. 6A is a diagram illustrating a state where ions (air vortex) are generated, and FIG. 6B is a time chart of energization of the electromagnetic coil 16 of the air gun 3. In FIG. 6A, the generation density of the air vortex is sparse in the space 41 and dense in the spaces 42 and 43. Thus, the amount of ion radiation can be controlled as necessary by controlling the timing of energization of the electromagnetic coil 16 by the control unit. Further, the ion density can be varied from dense to sparse by adjusting the emission timing. Timing adjustment is performed by controlling the positive and negative high voltage control units 35 and 36 using a microcomputer or the like (not shown) arranged in the control unit 17, and the timing can be made variable. . Further, the control unit 17 controls the positive or negative high voltage output to the positive discharge electrode 7 and the negative discharge electrode 8 independently of each other in accordance with the timing of energization of the electromagnetic coil 16, thereby generating air vortices. The ions in can be positive only, negative only, or both positive and negative. In this case, for example, by alternately discharging positive and negative ions, the positive and negative ions can be mixed in the vicinity of the final point of arrival such as the air vortex 39, and the positive and negative ions can be mixed. Ions can be ejected more efficiently than when they are released. If positive and negative ions are mixed and discharged, a decrease phenomenon in which positive and negative ions are neutralized in the air vortex 39 or the like occurs and the number of ions decreases. When the ion irradiation distance is long, positive and negative ions are radiated independently as described above, so that the reduction in the number of ions is suppressed and the efficiency is improved. When the distance is short, even if positive and negative ions are mixed and radiated, the phenomenon due to neutralization is less affected.

  Next, still another operation example in this embodiment will be described with reference to FIG. FIG. 7A is a diagram showing the state of ion (air vortex) generation in chronological order, and FIG. 7B is an air vortex firing timing diagram of the air cannon 3 at the moment when ON fires the air vortex. Is a rest period. FIG. 7C is a timing diagram of switching between positive and negative voltages by the high voltage control units 35 and 36 of the control unit 17. The top is a positive ion and the bottom is a negative ion. As shown in FIG. 7, by switching between positive and negative voltages at a predetermined timing, it is possible to discharge positive ions and negative ions alternately on an air vortex. When the released air vortex 39 collides with an object or reaches the final arrival point (point where the vortex disappears) such as the air vortex 39, the air vortex 39 is decelerated and the air vortices coming later sequentially collide with each other. The negative ions are mixed.

(Embodiment 2)
Next, the ion generator of Embodiment 2 of this invention is demonstrated with reference to FIG. In addition, about the same component as Embodiment 1, the same number is attached | subjected and description is abbreviate | omitted. FIGS. 8A and 8B are partial cross-sectional views of the ion generator 11 and the ion emitter 42 of the ion generator 41 of the present embodiment. In the ion generator 41 of the present embodiment, ion emission is performed. A movable blowout port 43, which is a separate component, is rotatably attached to the tip of the tube 4. By providing the movable blowout port 42 in this way, the air vortex firing direction of the air cannon 3 can be varied in the front, rear, left and right directions. FIG. 8A shows a state in which the movable outlet 43 is straight, and FIG. 8B shows a state in which the movable outlet 43 is inclined to the right by about 20 degrees (a state rotated as indicated by an arrow Y). With such a configuration, the ion radiation from the air cannon 3 can be freely directed in the target direction, so that the ion concentration can be increased at a specific location. The effect of sterilization, deodorization, etc. can be improved.

(Embodiment 3)
Hereinafter, the ion generator of Embodiment 3 of this invention is demonstrated with reference to FIG. In addition, about the same component as Embodiment 1, the same number is attached | subjected and description is abbreviate | omitted. 9A and 9B are partial cross-sectional views of the ion generator 10 and the ion emitter 45 of the ion generator 44 of the present embodiment, and FIG. 9C is the discharge electrode of the present embodiment. In the ion generator 44 of the present embodiment, the means 46 for cleaning the dust is a means for scrubbing the dust adhering to the tip portions of the discharge electrodes 7 and 8 in conjunction with the driving of the air cannon 3 to clean the discharge electrode. 46. Since the tips of the discharge electrodes 7 and 8 apply a high voltage, a dust collecting action is inevitably generated to adsorb dust in the air. When dust is adsorbed and accumulated, the electric field at the tips of the discharge electrodes 7 and 8 is lowered, and the amount of generated ions is reduced. Therefore, it is necessary to periodically clean the tips of the discharge electrodes 7 and 8. Specifically, the means 46 for cleaning the discharge electrode by scraping dust is provided with a brush 49 inside a through-hole 48 provided in the base 47 as shown in FIG. It is configured to be fixed to the plate 24. The brush 49 is a flexible brush 49 that allows the positive discharge electrode 7 and the negative discharge electrode 8 to pass through, and extends from the inner circumference of the through hole 48 toward the center. Further, the structure of the brush 49 may be any structure that can rub the tips of the positive discharge electrode 7 and the negative discharge electrode 8 or can pass through the very vicinity. Therefore, in addition to the above embodiments, the lattice structure having flexibility may be a mesh structure such as fine fabric, air filter, or non-woven fabric, and the shape does not have to be particularly specified. .

  The operation of the means 46 for scrubbing dust to clean the discharge electrode is because the partition plate 24 is pushed by the spring 25 when the electromagnetic coil 30 is not energized in FIG. The positive discharge electrode 7 and the negative discharge electrode 8 are in a state of penetrating the brush 49 of the base 47 of the means 46 for scraping dust to clean the discharge electrode. Since the brush 49 is flexible, it is pressed against the positive discharge electrode 7 and the negative discharge electrode 8. Next, in FIG. 9B, the electromagnetic coil 30 is energized to push out the air vortex. At this time, the partition plate 24 protrudes to the tip portions of the positive discharge electrode 7 and the negative discharge electrode 8 and covers the tips of the positive discharge electrode 7 and the negative discharge electrode 8 with the brush 49. Next, when the energization of the electromagnetic coil 30 is further turned off, the partition plate 24 is pushed back by the spring 25, but at that time, the brush 49 moves so as to trace the tips of the positive discharge electrode 7 and the negative discharge electrode 8, The dust adhering to the tips of the discharge electrode 7 and the negative discharge electrode 8 is scraped off. As described above, by operating the air cannon 3, the tips of the positive discharge electrode 7 and the negative discharge electrode 8 can be simultaneously cleaned, and the best discharge state can always be maintained.

(Embodiment 4)
Next, the ion generator of Embodiment 4 of this invention is demonstrated with reference to FIG. In addition, about the same component as Embodiment 1, the same number is attached | subjected and description is abbreviate | omitted. FIG. 10 is a partial cross-sectional view of an ion generator according to Embodiment 4 of the present invention. The ion generator 50 of the present embodiment has a configuration in which a discharge electrode part 51 that generates positive ions and a discharge electrode part 52 that generates negative ions can be independently driven by independent air cannon devices 53. It is what you have. In this case, the positive discharge electrode 54 of the discharge electrode portion 51 that generates positive ions and the negative discharge electrode 55 of the discharge electrode portion 52 that generates negative ions are independent, and the distance between the positive and negative discharge electrodes 54 and 55. By taking this, it is possible to prevent a decrease in the number of ions due to neutralization of positive ions and negative ions in the vicinity of the discharge electrodes generated when both the discharge electrodes 54 and 55 are close to each other. In FIG. 10, the ion emission cylinders 57 of the two air cannons 56 are integrally formed by a housing 584. However, when the distances between the positive and negative discharge electrodes 54 and 55 are further increased, they can be independent housings.

(Embodiment 5)
Next, the ion generator of Embodiment 5 of this invention is demonstrated with reference to FIG. In addition, about the same component as Embodiment 4, the same number is attached | subjected and description is abbreviate | omitted. As shown in FIG. 11, the ion generator 60 of the fifth embodiment includes a discharge electrode unit 51 that generates positive ions and a discharge electrode unit 52 that generates negative ions, which are independent of each other by an independent air gun device 53. Can be driven. Further, in the ion generator 60, when the directions of the tips of the positive and negative discharge electrodes 54 and 55 are extended, the directions of the positive and negative discharge electrodes 54 and 55 are made parallel so that they intersect within the reach limit of ions by the air gun 56. It is tilted inward and supported by the housing 61.

Thus, the discharge electrode generated when the positive and negative discharge electrodes 54 and 55 are close to each other by taking the distance between the discharge electrodes 54 and 55 by making the positive discharge electrode 54 and the negative discharge electrode 55 independent. It is possible to prevent a decrease in the number of ions due to neutralization of positive ions and negative ions in the vicinity. Further, by providing an angle so as to intersect within the arrival point of the air vortex by the air cannon 56, a space where positive ions and negative ions are mixed in the vicinity of the arrival point of the air vortex can be created. In the space where positive ions and negative ions are mixed, the positive ions and the negative ions are H ⁺ (H ₂ O) _m and O ²⁻ (H ₂ O) _n (m and n are arbitrary natural numbers), respectively. . When these positive ions and negative ions are released into the air at the same time, a chemical reaction occurs between them and hydrogen peroxide (H ₂ O ₂ ) or hydroxy radical (.OH), which is an active species, is generated. . Hydrogen peroxide (H ₂ O ₂ ) or hydroxy radical (.OH) exhibits extremely strong activity and can kill airborne bacteria and viruses present in the air.

  In the fourth and fifth embodiments shown in FIG. 10 and FIG. 11, by performing ion emission by the air cannon 56 at a constant sense interval, the ion discharge by the ion wind is performed when the ion emission by the air cannon 56 is stopped. Ions can be emitted from 54 and 55 in the vicinity, and at a little distance, ion radiation can be performed by the air cannon 56, and the characteristics of both ion radiation by the ion wind and ion radiation by the air cannon 56 can be utilized. In addition, it is possible to effectively release ions to a point far from the vicinity of the ion generator.

(Embodiment 6)

The ion generating element 62 in the case of the ion generating apparatus according to the sixth embodiment of the present invention is a plate-type ion generating element, and uses an ion generating electrode 63 that is baked and formed on both surfaces of a ceramic plate. One electrode is formed on the outer surface and the other electrode is formed on the lower surface of the ceramic, so it cannot be seen from the table. In this case, the air cannon 64 functions to discharge the ions generated on the upper surface of the ceramic ion generation electrode 63 in a direction along the surface by the ion emission cylinder 65 in a timely manner. Since the structure of the air gun 64 is the same as that described in the first to third embodiments, the description thereof is omitted.
