Description

  The present invention is an apparatus that generates an ion wind by corona discharge, and more specifically, an ion wind generator that generates an ion wind having a larger air volume. Further, in one aspect, the present invention relates to an apparatus and method for sterilizing / deodorizing an object such as dust, and in particular, corona discharge is performed in a space different from a space where the object is disposed, thereby generating ions and ozone. The present invention relates to an apparatus and a method for generating and sterilizing / deodorizing an ion / ozone wind to a space where an object is arranged. More specifically, the present invention relates to a highly airtight box, for example, a waste container such as garbage or diapers, a processing odor, a shoe or a boot of a garbage disposal machine, a box / toilet / toilet tank for storing, an airtight The present invention relates to an environmental device for sterilization and deodorization that is mounted on a highly-contained container with a refrigeration / refrigeration device, a vehicle with a refrigeration / refrigeration device, a refrigerator, an indoor / interior air conditioner, and the like.

  Along with the aging society, demand for filth containers such as diapers is increasing in proportion to the population requiring nursing care. It is unsanitary. In addition, each household, restaurant, and the like also have a garbage storage box, but each time it is opened, it emits a bad odor due to the growth of various germs, which is a heavy burden on housewives and workers. Garbage disposal machines are also increasing along with the growth of biotechnology, but the bad smell emitted around the disposal machines is a serious problem during operation. In addition, overseas and domestic logistics such as refrigeration, refrigeration, and room temperature products are mainly transported by transport containers and trucks, and there are many marine containers with air conditioners, land containers, container-type trucks, etc. Residual odors in cargo and mold odors in air conditioners are problematic. Furthermore, odors are also a problem in air conditioners such as warehouses, refrigerators, rooms, and vehicles depending on the usage of stored materials.

  Here, as a method for solving the above problem, a simple germicidal deodorant such as a spray type has been proposed. However, when used in a trash bin or a garbage storage box, the present situation is that a bad odor is emitted when the container is opened. In addition, when used in an air conditioner (for example, spraying or circulation sterilization method), the parts that cannot be cleaned inside the air conditioner, or if an odor or mold odor remains even after cleaning, the odor will be transferred to the next loaded cargo. It has become. Furthermore, as another solution technique, a method of sucking air from a space to be sterilized and deodorized and adsorbing or removing contaminants with a filter and an expensive malodor removing catalyst have been proposed. However, maintenance such as filter replacement is indispensable due to long-term use, and because the performance of the filter is not sufficient, if the satisfactory performance is not obtained or even if the performance is good, the large and expensive catalyst body, In addition, maintenance and management costs are often high.

  By the way, in recent years, air cleaners and air conditioners that generate negative ions and ozone are widely used for indoor air cleaning and refreshing. Many techniques have been proposed for deodorizing the target space using a negative ion / ozone generator that simultaneously generates negative ions and ozone having a deodorizing effect.

  First, the negative ion / ozone generator according to Patent Document 1 is an apparatus that is assumed to be attached to the ceiling of a room, and is characterized in that the positive electrode is disposed below the negative electrode. According to this, a downward airflow containing negative ions and ozone can be generated without using a fan or a motor.

  Next, the negative ion / ozone generator according to Patent Document 2 includes a negative electrode having a needle-like tip and a cylindrical ground electrode arranged concentrically in parallel to the negative electrode, and the negative electrode and the ground electrode are relatively disposed. The negative electrode or ozone is generated by adjusting the distance between the tip of the negative electrode and the end face of the ground electrode by applying a high voltage to the negative electrode.

  Next, the negative ion / ozone generator according to Patent Document 3 is a device that generates ozone and negative ions by applying a DC high voltage between the needle electrode and the ground electrode to cause corona discharge at the tip of the needle electrode. is there.

  Next, the negative ion / ozone generator according to Patent Document 4 has a positive electrode made of a metal plate provided with one or a plurality of holes having a raised portion around the periphery, and the tip of the negative electrode is the positive electrode. It is located in the vicinity of the hole. With this configuration, a sufficient air flow is generated by the discharge, so that it is possible to generate an air flow that diffuses the generated negative ions and ozone into the space without using a blower such as a fan or a pump. .

  The inventions according to Patent Documents 1 to 4 describe that ions and ozone are generated and applied to an object, but these technologies are in a space to be sterilized or deodorized such as the inside of a trash can. It is assumed that it is arranged and discharged. For example, in a trash can, odorous organic matter may be decomposed by microorganisms to produce flammable gas such as methane gas. If discharge occurs under such conditions, a fire or explosion may occur due to the occurrence of a spark. There is a risk that will occur.

  Therefore, in order to remove such dangers, external discharge is performed outside the space where the object is placed to generate ions and ozone and introduce these products into the space where the object is placed. Development of a mold sterilization / deodorization apparatus has been studied (Patent Document 5).

  However, in the inventions according to Patent Documents 1 to 5, it is possible to generate ions and ozone, but it is difficult to configure the generated ions to spread over the entire room. More specifically, in these technologies, since the generated wind of the ion wind containing the generated ions and ozone is weak, in order to spread the ions and ozone throughout the room, a separate blower or the like Therefore, it is necessary to boost the ion wind. As a result, the ion wind can be boosted, but the ions contained in the ion wind are diluted. Furthermore, in these technologies, the ozone concentration may be high in the vicinity of the jet outlet, so that the articles near the device are unintentionally bleached by the ozone that is simultaneously generated when ion wind is generated in the device. There was a case where it was done. In such a case, as a means for reducing the ozone concentration, a method using a filter or the like has been proposed. However, there is a problem that the ion concentration in the ion wind is also reduced or that the filter needs to be replaced. there were.

  Before explaining the details of the ion / ozone wind generating apparatus according to the present invention, referring to FIGS. 1 to 4, the ion / ozone wind generating apparatus according to the present invention (the fourth and fifth embodiments described later) will be described. The outline of such an ion / ozone wind generator will be described. Here, the present invention is not limited to these examples. For example, the embodiments and modifications given as examples in this specification should be understood as being applied to specific ones. Any combination may be used. For example, it should be understood that a modification example of an embodiment is a modification example of another embodiment, and even if one modification example and another modification example are described independently, there is the modification example. It should be understood that a combination of the modified example and another modified example is also described. Further, numerical values as specific examples shown in the embodiments and modified examples {for example, the diameter and length / thickness of the discharge electrode and the counter electrode, the voltage difference between the discharge electrode and the counter electrode, the discharge electrode and the counter electrode, which will be described later, It is to be understood that the separation distance, etc. is merely an example, and may be appropriately changed as long as it does not significantly depart from the spirit of each embodiment or modification.

  First, an outline of an ion / ozone wind generator 100-4 according to one embodiment (fourth embodiment described later) of the present invention will be described with reference to FIG.

  As shown in FIG. 1, an ion / ozone wind generator 100-4 according to this embodiment includes a needle-like discharge electrode 120-4 and an annular counter electrode 130-4, and between these electrodes. A cylindrical ion wind guide member 140-4 (guide member 140-4) capable of introducing the generated ion wind is provided. More specifically, the guide member 140-4 has an outlet 141-4 (constriction 141-4) that is an opening through which ion wind is ejected (in this embodiment, the constriction that has the narrowest cross-sectional area in the member). The portion 141-4 is also the jet outlet 141-4.), An intake opening 142-4 serving as an inlet having a larger diameter (ring diameter) than the jet outlet 141-4, and an intake opening 142-4 A reduced diameter portion 140r-4 (inclined portion) that is reduced in diameter toward the ejection port 141-4. Thus, in this embodiment, the diameter (ring diameter) of the intake opening 142-4 is configured to be larger than the diameter (ring diameter) of the counter electrode 130-4 (for example, the guide member 140-4 The main feature is that the counter electrode 130-4 can be visually recognized as a ring from the outlet 141-4 when viewed in the central axis direction. As a specific flow path of the ion wind, the ion wind generated by the counter electrode 130-4 passes through the internal space of the guide member 140-4 and goes from the intake opening 142-4 side to the jet outlet 141-4 side. And will be ejected from the ejection port 141-4 (the principle of ion wind generation will be described later). In addition, although the jet nozzle 141-4 (constriction part 141-4), the intake opening 142-4, etc. point out each structure part (edge part) in the guide member 140-4, the said structure part (edge part). May also refer to the space formed by.

  Next, operations and effects of the ion / ozone wind generator 100-4 according to this embodiment will be described with reference to FIG.

  For example, as shown in FIG. 2 (b), a conventional ion / ozone wind generator having a guide member is arranged {on the counter electrode, straight toward the spout side shown in FIGS. A8 and A9. In particular, a device provided with a truncated conical guide member 140 having a shape in which the cross-sectional diameter is small (the cross-sectional diameter is reduced) is included. Conventionally, the reason why such a truncated conical guide member is arranged is to increase the ion wind by concentrating the ion wind inside the guide member. At first glance, the ion / ozone wind generator 100-4 according to the present embodiment seems to be similar to such a conventional ion / ozone wind generator. However, the guide member 140-4 according to the present embodiment is created based on a concept different from that of the conventional guide member 140.

  Specifically, as a result of experiments conducted by changing the shape of the guide member in various ways, the present inventor increases the shape of the outlet 141-4 of the guide member 140-4 (the diameter of the outlet 141-4). 2 is designed to be larger than the ring diameter of the counter electrode 130-4), as shown in FIG. 2A, the guide member functions (occurs) in the direction of diffusing rather than concentrating the ion wind. Ion wind diffused. Regarding the principle of the effect according to the present embodiment, the present inventor predicts as follows.

  According to the ion / ozone wind generator 100-4 according to the present embodiment, the discharge electrode 120-4 and the counter electrode are formed by configuring the ring diameter of the jet nozzle 141-4 to be larger than the ring diameter of the counter electrode 130-4. It is considered that the ion wind generated between the guide member 140-4 and the jet member 141-4 is pushed to the front surface in the form of a certain degree along the shape (annular shape) of the counter electrode 130-4. {FIG. 2B is a schematic cross-sectional view of the ion / ozone wind generator 100-4, where the discharge point 120x-4 of the discharge electrode 120-4, the power reception point 130x-4 of the counter electrode 130-4, and The dotted line arrow indicates that the discharge is performed at the power receiving point 130y-4. However, since the discharge point is continuously formed in the counter electrode 130-4, the discharge electrode 120-4 is connected to the counter electrode. 130-4 Discharge for the entire edge portion Okonawaru}. In this case, a portion through which the ion wind easily passes (a region corresponding to the counter electrode 130-4 with respect to the shadow of the ejection port 141-4 when projected in the ring axis direction of the counter electrode 130-4), and the ion wind Is difficult to pass through (a region corresponding to a portion in which the counter electrode 130-4 is cut from the ejection port 141-4 when projected in the ring axis direction of the counter electrode 130-4). It will be uniform. Therefore, apart from the ion wind, the wind from the intake opening 142-4 toward the jet outlet 141-4 along the inner wall surface of the guide member 140-4 (the wind passing through the portion where the ion wind is difficult to pass) Occurs. As a result, it is considered that a turbulent flow that pulls the ion wind in the outer circumferential direction of the jet nozzle 141-4 is generated at the jet nozzle 141-4, and the ion wind is diffused by entraining the ion wind. Furthermore, according to the present embodiment, since the distance between the guide member 140-4 and the ion wind generated at the counter electrode is easily separated, the ion wind is generated before reaching the ejection port 141-4. It becomes difficult to come into contact with the guide member 140-4 (further, the wind passing through the portion where the ion wind is difficult to pass protects the ion wind itself), and the attenuation of the ion wind inside the guide member 140-4 is suppressed. (Furthermore, the ion wind is gathered in a form along the inner wall of the guide member 140-4 while being hardly contacted with the guide member 140-4). As a result, an ion wind having a sufficient air volume (including sufficient ions) reaches the jet nozzle 141-4 and further diffuses at the jet nozzle 141-4. It is possible to deliver ions over a wide range while reducing the ozone concentration. It should be noted that the difference in ion concentration between the ion wind and the wind flowing in from the intake opening 142-4 is also involved in the generation of turbulent flow that diffuses the ion wind, further enhancing the diffusion effect of the ion wind. There is a possibility.

  On the other hand, when the ring diameter of the jet nozzle 141 of the guide member 140 is equal to or less than the ring diameter of the counter electrode, as in the conventional apparatus shown in FIG. The wind that wraps around from the outside of the electrode joins the ion wind inside the guide member 140. As a result, since the integrated wind is ejected from the jet outlet 141 as a whole, it is considered that the turbulent flow that pulls the ion wind in the outer peripheral direction of the jet outlet 141 is unlikely to occur (as a result, the jet The ozone concentration in the vicinity of the outlet 141 remains high). In addition, since the guide member 140 and the ion wind are easily in contact with each other, the ion wind is attenuated inside the guide member 140. As a result, the generated ion wind may be poor in wind power, and ions (ion wind) are delivered over a wide range. It becomes difficult to let you.

  As described above, the ion / ozone wind generating apparatus 100-4 according to the present embodiment changes the shape of the guide member 140-4 to perform efficient diffusion without separately providing a blower or the like and deliver it to the target space. The ozone concentration in the vicinity of the jet nozzle 141-4 is lowered while maintaining the amount of ions to be performed (blowing ions widely).

  Next, an outline of an ion / ozone wind generator 100-5 according to a second embodiment (a fifth embodiment described later) of the present invention will be described with reference to FIG.

  As shown in FIG. 3, an ion / ozone wind generator 100-5 according to this embodiment includes a cylindrical counter electrode 130-5 having an internal space, and a part (tip) in the internal space of the counter electrode 130-5. ) In a state of being inserted into the needle-shaped discharge electrode 120-5. More specifically, the counter electrode 130-5 has an outlet 130α-5 (constriction 130α-5) that is an opening through which ion wind is ejected (in this embodiment, the constriction that has the narrowest cross-sectional area in the member). Portion 130α-5 is also a jet outlet 130α-5), an intake opening portion 130β-5 serving as an intake port having a larger diameter (ring diameter) than the jet port 130α-5, and jetting from the intake opening portion 130β-5 A reduced diameter portion 130r-5 (inclined portion) that is reduced in diameter toward the outlet 130α-5. Thus, the main feature of the present embodiment is that the diameter (ring diameter) of the intake opening 130β-5 is configured to be larger than the diameter (ring diameter) of the jet outlet 130α-5. The jet outlet 130α-5, the intake opening 130β-5, and the like indicate each component (edge) in the counter electrode 130-5, but indicate a space formed by the component (edge). In some cases.

  Next, the operation and effect of the ion / ozone wind generator 100-5 having the above-described structure will be described with reference to FIG.

  Since the ion / ozone wind generator 100-5 according to the present embodiment has the above-described structure, as shown in FIG. 4, the discharge electrode 120-5 and the entire inner wall surface of the counter electrode 130-5 (In this embodiment, discharge is mainly performed from the tip of the needle serving as the end thereof. However, since the discharge point can be other than the tip of the needle, the discharge electrode 120 in FIG. -5 is schematically depicted such that the discharge point of -5 is not only the tip of the needle). More specifically, the distance between the inner wall surface and edge portion of the counter electrode 130-5 and the discharge electrode 120-5 (particularly, the tip of the discharge electrode 120-5) is determined from the intake opening 130β-5 to the jet outlet 130α-5. Therefore, the discharge is not locally generated only at the edge portion of the counter electrode 130-5, but is dispersedly and stably repeated over a wide area of the entire inner wall surface of the counter electrode 130-5. Discharge (surface discharge) is performed. As a result, local discharge is reduced, and the ozone concentration contained in the generated ion wind can be reduced. Furthermore, since the counter electrode 130-5 has a shape in which the cross-sectional area gradually decreases from the intake opening 130β-5 side toward the jet outlet 130α-5, the counter electrode 130-5 occurs in the vicinity of the intake opening 130β-5. The ions (ion wind) generated inside the counter electrode 130-5 including the ions are surely guided to the vicinity of the jet outlet 130α-5. As a result, an ion wind having a high ion concentration and torque is ejected.

  On the other hand, in the case of a conventional ion / ozone wind generator provided with a simple cylindrical counter electrode and a discharge electrode facing the cylindrical inlet, its edge (the end of the cylinder facing the discharge electrode). As a result of local discharge being easily performed at (1), an ion wind with an increased ozone concentration may occur. Furthermore, the ion wind generated from the counter electrode is decelerated due to the reaction between the inner wall surface of the counter electrode and the ion wind, and the ion wind tends to stay inside the counter electrode. As a result, the ion wind ejected from the cylindrical electrode has a high ozone concentration, but the ion wind force is not sufficient (does not have wind force enough to diffuse around).

  As described above, the ion / ozone wind generator 100-5 according to the present embodiment designs the shape of the counter electrode 130-5 while paying attention to the facing relationship between the counter electrode 130-5 and the discharge electrode 120-5. Thus, the ozone generation amount itself is suppressed, and an ion wind with torque is generated.

  Examples of the ion / ozone wind generator according to the present invention include the above-described configurations (ion / ozone wind generator 100-4 and ion / ozone wind generator 100-5). Various ion / ozone wind generators have been created. Hereinafter, such an example will be described as a first embodiment to a third embodiment, and by describing in detail the ion / ozone wind generator according to the first embodiment, first, the principle explanation of the generation of ion wind will be given, Next, the ion / ozone wind generators according to the second and third embodiments will be described as aspects of the ion / ozone wind generator created up to the present invention. The ion / ozone wind generator (ion / ozone wind) according to the present invention, which has been created based on various theories found in the creation of such an ion / ozone wind generator, has been developed. The generator 100-4, the ion / ozone wind generator 100-5), and other components that serve as peripheral technology thereof will be sequentially described in detail in the fourth embodiment and the fifth embodiment.

<< First Embodiment >>
First, the ion / ozone wind generator according to the present embodiment has an electrode pair having a needle-like electrode and a counter electrode, generates a potential difference between the needle-like electrode and the counter electrode, and generates corona discharge. Generates ions, ozone and ionic wind. Further, the ion / ozone wind generating apparatus according to the present embodiment includes a main annular counter electrode having a planar shape and a sub-annular counter electrode having a planar shape surrounding the main annular counter electrode. The longest distance between the tip of the electrode and the main annular counter electrode is shorter than the shortest distance between the tip of the needle electrode and the sub annular counter electrode.

  With this configuration, an ionic wind having a large air volume is obtained. In the case of a mere cylindrical or one flat circular counter electrode, the discharge discharges in a donut shape along the inner side of the cylindrical electrode of the counter electrode at the shortest distance or the inner side of the flat circular electrode, and a donut ion wind is generated. The center of the donut is windless. Therefore, the ionic wind becomes weak as a result of the loss that uses the energy that the generated ionic wind induces the windless center. The problem is solved by providing the main annular counter electrode and the sub annular counter electrode as in this embodiment.

  The ion / ozone wind generator according to this embodiment has an electrode pair having a needle electrode and a counter electrode, generates a potential difference between the needle electrode and the counter electrode, and generates ion / ozone by corona discharge. And an ionic wind is generated. In general, an ion wind is generated by repeatedly colliding with air molecules while ions emitted from the needle electrode during the corona discharge migrate toward the counter electrode, so that the needle winds from the needle electrode toward the counter electrode. It is said that the resulting air flow. That is, it is an air flow generated according to the flow direction of ions generated during discharge. Hereinafter, the detailed structure of the ion / ozone wind generator according to the present embodiment will be described.

  A schematic structure of the ion / ozone wind generator according to this embodiment is shown in FIG. Here, FIG. A1 (a) is a conceptual front view of the counter electrode of the apparatus, and FIG. A1 (b) is a conceptual side view of the ion / ozone wind generating apparatus 100. The ion / ozone wind generator 100 according to this embodiment includes an electrode pair 110 having a needle electrode 120 and a counter electrode 130. Here, the counter electrode 130 includes a circular annular electrode 131 located on the innermost side disposed on the extension line axis of the needle-like electrode 120, and an outer circular annular electrode 132 having a different radius arranged coaxially with the electrode. . That is, these annular electrodes are disposed so as to be perpendicular to the annular plane and to be positioned on an axis passing through the center of gravity (circular center) of the ring. By using the counter electrode having such a circular shape among the annular counter electrodes, the distance from the tip of the needle-like counter electrode to each part of the counter electrode becomes substantially equal, so that discharge unevenness is reduced. In addition, since the needle-like electrodes are arranged on the axis of the ring in this way, the ionic wind generated from the main annular counter electrode is particularly strong.

  These annular electrodes 131 and 132 are preferably bridged so as to be energized by a connecting member such as a bridge 139. With this configuration, each annular electrode can be made equipotential, It becomes easy to adjust the positional relationship between these electrodes. For example, when connected by a corrugated member, a portion having a substantially triangular shape is formed between the main annular counter electrode and the sub-annular counter electrode, so that unevenness occurs in corona discharge and a large amount of ion wind is forward. Will not be pushed out. Therefore, a conceptual straight line connecting the connecting portion between the connecting member and the secondary annular counter electrode and the connecting portion between the connecting member and the main annular counter electrode passes through the center of gravity of the main annular counter electrode so as not to interfere with the generation of ion wind. It is preferable to arrange the connecting members as described above. By connecting in this way, the generation unevenness of the ionic wind due to the discharge unevenness is less likely to occur.

  The main annular counter electrode and the sub-annular counter electrode constituting the counter electrode are preferably arranged in the same plane. Since it is the distance that makes the discharge efficiency of the sub-annular counter electrode gradually weaker than that of the main annular counter electrode, it is preferable to arrange the same on the same plane because the distance can be easily changed.

  The needle electrode 120 and the counter electrode 130 are connected to a voltage applying means or a ground, respectively, and in use, a potential difference is generated between the electrodes to discharge. Here, the positional relationship between the distal end portion P of the needle-like electrode 120 and the innermost main annular counter electrode 131 is preferably a positional relationship that is most suitable for emitting ion wind, and such a distance is set. By disposing, a relatively strong ion wind is emitted as the annular counter electrode having a smaller radius located at the center of the counter electrode, and as a result, a large amount of ion wind can be obtained. If it exists in such a positional relationship, the cyclic | annular counter electrode may be distribute | arranged on the same plane and may be distribute | arranged on another plane. In addition, the broken line arrow shown from the front-end | tip part P to the cyclic | annular counter electrode in the figure shows the ion migration direction by corona discharge.

  A positional relationship suitable for emitting ion wind will be described with reference to the schematic diagram of FIG. In FIG. A2 (a), the positional relationship between the annular counter electrode 131 and the tip portion P of the needle electrode 120 is shown using the cross section of the annular counter electrode 131 located in the innermost part. In FIG. The positional relationship between the annular counter electrode 132 and the tip portion P is shown.

First, when there is a positional relationship between the tip portion P and the annular counter electrode 131, ions migrate toward the electrode in the direction of the arrow. That is, the ion wind is theoretically generated with an angle of θ ₁ from the tip portion P. Therefore, as a whole, an ion wind is generated in the direction of the generatrix line connecting the apex of the cone having the tip P as the apex to the end of the bottom surface. That is, ion wind is generated also in the outward direction of the annular counter electrode, but as a whole, the ion wind is pushed out from the center of the annular counter electrode in the front direction. On the other hand, in the case of a ring electrode having a relatively large radius like the annular counter electrode 132 shown in FIG. A2 (b), the ion wind is theoretically generated at an angle of θ ₂ from the tip P. Become. That is, since the angle becomes larger, the ionic wind derived from this electrode has more components emitted toward the outer side of the annular counter electrode, and the volume of the ionic wind pushed toward the front surface becomes smaller.

  Further, corona discharge is likely to occur with respect to the counter electrode located near the needle electrode. As the annular counter electrode is located at the center, the distance from the distal end portion P of the needle electrode becomes closer. That is, since the probability of occurrence of corona discharge is higher in the annular counter electrode positioned at the center, the absolute counter pressure of the generated ion wind is also higher in the annular counter electrode positioned at the center.

  As described above, the annular counter electrode 131 located in the innermost portion is advantageous in the direction in which ion wind is generated, and the absolute wind pressure in which ion wind is generated is also large. Therefore, the counter electrode as shown in FIG. A1 is in a state in which the ion wind emitted from the annular counter electrode becomes stronger as the radius of the annular electrode becomes smaller. By arranging in this way, no stagnation occurs due to the ionic wind emitted from the external electrode, and the ionic wind emitted from the center is involved, so the air volume increases, and the ions and ozone generated by the discharge are reduced. Since the action of extruding to the front surface by the ionic wind is obtained, the effect of sterilization and deodorization is enhanced. Further, it is more preferable that the distance between the annular counter electrode 131 located at the innermost part and the tip end portion P is maintained at a distance that is most easily discharged in corona discharge. However, if the diameter of the annular portion of the counter electrode is simply made large, a large discharge reaction occurs, but since the discharge occurs in a donut shape, the central portion of the windless area is also large due to the absence of the counter electrode portion at the annular center of the counter electrode. As a result, discharge unevenness occurs and a donut-like ion wind is generated. As a result, the outer periphery and the central portion of the generated ion wind are in a no-wind state, and the donut-like ion wind induces a no-wind region so that no strong wind is generated. If the diameter of the annular part is small, ion wind with strong wind pressure is emitted, but the amount of generation is small, so by arranging the secondary annular counter electrode, which is the secondary generation pole, on the outer periphery of the main annular counter electrode, the mainstream wind has a small diameter at the center. While generating strong wind pressure, the outer circumference has a large diameter and weak wind pressure but emits a side stream with a large air volume. In other words, the counter electrode according to the present embodiment has a large air diameter, the wind pressure is weak but the air volume is large, and if the diameter is small, the wind pressure is strong but the air volume is small. The shape is compatible with wind pressure and large amount of generation.

  By making the counter electrode planar, the ionic wind generated from the counter electrode is not decelerated due to the reaction between the obstacles such as the wall surface and the ionic wind, and the main ionic wind generated from the main annular counter electrode; Since the secondary ion wind generated from the secondary annular counter electrode is immediately synthesized, the main ion wind can quickly obtain the synergistic effect of the tail wind by the surrounding secondary ion wind immediately after the generation, so that a larger volume of ion wind can be generated. Can be obtained. On the other hand, when the counter electrode is, for example, cylindrical, a wall surface is present in the counter electrode, so that the ion wind generated from the counter electrode is decelerated due to the reaction between the wall surface and the ion wind. Thus, by making the counter electrode planar, it becomes possible to obtain a large amount of ionic wind, unlike the case of a cylindrical shape or the like. In addition, since the shape of the counter electrode is not a cylindrical shape but a flat shape, the device can be miniaturized, and even if the device is miniaturized in this way, The air volume is not reduced. In addition, the planar electrode facilitates cleaning of the counter electrode. Note that, for example, in the case of the wire mesh counter electrode as in Patent Document 9 described above, each counter electrode is not annular, and the planar normal vector in each counter electrode is not substantially in the same direction. The ion wind generated from the counter electrode is decelerated due to the fact that uneven discharge is likely to occur and the ion wind generated from the counter electrode is not uniform, etc. (the ion wind generated at each counter electrode is optimal) Not synthesized), which is not preferable.

  In the ion / ozone wind generator according to this embodiment, the longest distance between the tip of the needle electrode and the main annular counter electrode is shorter than the shortest distance between the tip of the needle electrode and the sub annular counter electrode. By arranging the needle-like electrode and the counter electrode in such a distance relationship, the ion wind with the strongest wind pressure is generated from the opening formed in the center of the main annular counter electrode, and from the surrounding sub-annular counter electrode. Since an ionic wind having a low wind pressure is generated, a large amount of ionic wind can be obtained. When deviating from the positional relationship between the needle-like electrode and the counter annular electrode, the ion wind is mainly generated from the space between the main annular counter electrode and the sub-annular counter electrode, resulting in uniform wind. For this reason, the ionic wind released in the air becomes weak, and a reaction also occurs when a guide member is provided.

  The number of annular counter electrodes constituting the counter electrode 130 is not limited to two as shown in FIG. A1, and a large number of annular counter electrodes are provided like the annular counter electrodes 131 to 133 as shown in FIG. A3. It may be. Fig. A3 (a) is a conceptual front view of the counter electrode 130 of the apparatus, and Fig. A3 (b) is a conceptual side view of the ion / ozone wind generating apparatus 100. Here, the case where three annular counter electrodes are used has been described. However, any number of annular counter electrodes constituting the counter electrode may be provided as long as the distance relationship with the needle electrode is satisfied. By providing a large number of electrodes in this way, even if one electrode becomes dirty and no longer discharges, it can be discharged by another electrode, leading to an improvement in the operational stability of the apparatus.

  As shown in FIG. A4, the counter electrode according to the present embodiment may be polygonal. Also in this case, each needle electrode and the counter electrode are positioned such that the longest distance between the tip of the needle electrode and the main annular counter electrode is shorter than the shortest distance between the tip of the needle electrode and the sub annular counter electrode. It is arranged in. Fig. A4 (a) is a conceptual front view of the counter electrode of the device, and Fig. A4 (b) is a conceptual side view of the ion / ozone wind generating device 100. Even in this triangular shape, the ion wind generated from the main annular counter electrode is smaller than the ion wind generated from the sub annular counter electrode, and a large amount of ion wind can be obtained. Although the main annular counter electrode is shown in a circular shape here, it may be a polygon more than a triangle. In addition, when the annular counter electrode is polygonal, it is advantageous that the number of sides is larger because the number of points that are the shortest distance from the needle-like electrode is increased, so that uneven discharge is less likely to occur.

  As shown in FIG. A5, a plurality of needle-like electrodes may be provided like the needle-like electrodes 121-123. In this case, all the acicular electrodes and the counter electrodes are positioned such that the longest distance between the tip of the acicular electrode and the main annular counter electrode is shorter than the shortest distance between the tip of the acicular electrode and the sub annular counter electrode. Has been. Fig. A5 (a) is a conceptual front view of the counter electrode of the device, and Fig. A5 (b) is a conceptual side view of the ion / ozone wind generator 100. By providing a plurality of needle electrodes in this manner, more dielectric breakdown occurs and molecules collide more easily than in the case of a single electrode, and the ability to push out increases, so that a large amount of ozone can be generated.

  FIG. A6 is a schematic diagram illustrating an example of the counter electrode according to the present embodiment. Here, the counter electrode is formed by providing a hole in the plate. FIG. A6 (c) is a conceptual diagram of a plate-like counter electrode 130c having a circular counter electrode. The counter electrode includes a first counter electrode 130c-1 and a second counter electrode 130c-2. The first counter electrode 130c-1 is formed with a circular main annular counter electrode 131c-1 at the center, and a circular sub annular counter electrode 132c-1 is formed around the first counter electrode 130c-1. Sub-circular counter electrodes 133c-1, 134c-1, and 135c-1 are further formed on the outer periphery of the electrode 132c-1. A connecting member 139c-1 is formed between these counter electrodes. Similarly, the second counter electrode is also formed with a circular main annular counter electrode 131c-2 at the center, and a circular sub annular counter electrode 132c-2 is formed around it. Sub-circular counter electrodes 133c-2 and 134c-2 are further formed on the outer periphery of the electrode 132c-2. A connecting member 139c-2 is formed between these counter electrodes. Needle-like electrodes are arranged at appropriate positions with respect to these plate-like counter electrodes.

FIG. A6 (b) is a diagram showing a schematic configuration of the plate-like counter electrode 130b. In the plate-like counter electrode 130b, the main annular counter electrode has a circular shape, and the surrounding sub-annular counter electrode has a hexagonal shape. The plate-like counter electrode 130b includes a first counter electrode 130b-1 and a second counter electrode 130b-2. A circular main annular counter electrode 131b-1 is formed at the center of the first counter electrode 130b-1, and a hexagonal sub-annular counter electrode 132b-1 is formed around it. Sub-circular counter electrodes 133b-1, 134b-1, and 135b-1 are formed on the outer periphery. These counter electrodes are connected by a connecting member 139b-1.
Similarly, a circular main annular counter electrode 131b-2 is formed at the center of the second counter electrode 130b-2, and hexagonal sub-annular counter electrodes 132b-2 to 134b-2 are formed around it. These electrodes are connected by a connecting member 139b-2.

  FIG. A6 (a) is a diagram showing a schematic configuration of the plate-like counter electrode 130a. In the plate-like counter electrode 130a, a circular main annular counter electrode and an annular sub-annular counter electrode are formed around it. The plate-like counter electrode 130a includes a first counter electrode 130a-1 and a second counter electrode 130a-2. A circular main annular counter electrode 131a-1 is formed at the center of the first counter electrode 130a-1, and a plurality of sub-annular counter electrodes 132a-1 are formed around it. In FIG. A6 (a), a representative example of the sub annular counter electrode 132a-1 is shown, but 132a-1 formed around the main annular counter electrode 131a-1 is also a sub annular counter electrode. is there. By forming in this way, the member formed between the sub-annular counter electrodes is in a state of spreading radially from the main annular counter electrode, so in addition to the ion wind generated from the main annular counter electrode, As the distance from the main annular counter electrode increases, the amount of ion wind continuously decreases. Similarly to the first counter electrode, the second counter electrode 132a-2 has a main annular counter electrode 131a-2 and a sub-annular counter electrode 132a-2 at the center.

  FIG. A6 (d) is a common side view of the plate-like counter electrodes 130a to 130c.

  As shown in FIG. A7, an ion / ozone wind generator having a plurality of electrode pairs 110 according to this embodiment is suitable. FIG. A7 is a conceptual plan view of the ion / ozone wind generator 100. FIG. Two electrode pairs are arranged on the left and right of the electrode pair arranged in the center, and the ion wind generation direction of the two electrode pairs arranged on the left and right with respect to the ion wind generation direction of the electrode pair arranged in the center It is preferable that they are arranged so as to intersect each other. In addition, it is more preferable that the ion wind generated from each electrode pair is concentrated at one point. By using such an apparatus, ion winds emitted from each electrode pair can be merged, and an ion wind with a larger air volume can be obtained.

  As shown in FIG. A8, it is preferable that an ion wind guide member 140 having a truncated cone shape is provided. FIG. A8 (a) is a conceptual front view of the counter electrode 130 of the apparatus, and FIG. A8 (b) is a conceptual side view of the ion / ozone wind generating apparatus 100. The ion wind generated from the annular counter electrode located outside the ion wind generated from the annular counter electrode 131 located at the innermost part of the counter electrode 130 is aggregated (combined) to the ion wind jet port 141. By sending, the air volume of the ionic wind pushed out to the front surface increases. Even if the guide member is provided in this manner, the ion wind generated on the outside is smaller than the ion wind generated on the innermost side, so that it is pushed forward so as to be drawn into the center ion wind without staying. . The guide member has a shape in which the opening cross-sectional area gradually decreases. When a guide member having such a shape is provided, the ion wind generated from the counter electrode is uniform, and the donut wind that does not generate wind pressure at the center has a shape that reduces the cross-sectional area with respect to the blowing action. The wind collides with the inner wall of the guide member and turbulence is generated, causing a reaction inside the guide member, resulting in a slight wind, but if the main ion wind is strong and the sub ion wind is weak, even when the guide member is narrowed to a small diameter, Therefore, the collision with the inner wall of the guide member is naturally weakened, and the main ion wind is combined with the secondary ion wind and concentrated and ejected.

  Further, it is preferable that a blower path 150 is provided at the jet outlet 141 of the guide member 140. Here, the delivery path is not particularly limited as long as the direction of the ejected ion wind can be adjusted, but it is preferable that the delivery path is a tubular member having the same diameter as the ejection port 141. Here, the material of the air blowing path is not particularly limited, and examples thereof include a hose and a vinyl chloride pipe. The air blowing path can be used so that ion winds generated from these electrode pairs are easily collected when a plurality of electrode pairs are provided as will be described later. Further, when the electrode pair is used alone, ions and ozone may be sent into the sterilization / deodorization target space or the like through the sending route.

  As shown in FIG. A9, it is preferable to provide a plurality of electrode pairs 110 provided with these guide members 140. When three electrode pairs 110 are provided, two electrode pairs are arranged on the left and right of the electrode pair arranged at the center, and arranged on the left and right with respect to the ion wind generation direction of the electrode pair arranged at the center. The two electrode pairs are arranged so that the ion wind generation directions intersect each other. In addition, it is preferable that the ion wind generated from each electrode pair is concentrated at one point. By comprising in this way, the ion wind of large air volume can be obtained by making the ion wind generated from each electrode pair merge.

  As shown in FIG. A10, it is preferable to provide six electrode pairs 110 provided with guide members 140 (here, needle-like electrodes are omitted for ease of drawing). Fig. A10 (a) is a conceptual plan view of an ion / ozone wind generator, Fig. A10 (b) is a conceptual side view of the ion / ozone wind generator, and Fig. A10 (c) is an ion / ozone wind generator. It is the conceptual front view seen from the jet nozzle side of the apparatus. In this case, the electrode pairs are arranged in two upper and lower stages for every three pairs, and arranged according to the arrangement method for the three electrode pairs shown above for each of the upper and lower stages {FIG. A10 (a)}. Are arranged so that ion winds generated from the group of electrode pairs merge {FIG. A10 (b)}. Here, it is preferable to arrange the ion wind generated from each electrode pair so that one point is concentrated. That is, by arranging the ion winds generated from the electrode pairs located at the center of the upper and lower stages at an angle, the ion winds from each electrode pair can be merged to obtain a large air volume ion wind. be able to.

<Another form of electrode pair>
According to the ion / ozone wind generator 100 described above, a sufficient amount of ion wind can be obtained, but there is room for further improvement in terms of miniaturization and portability. Therefore, as compared with the ion / ozone wind generator 100 described above, the ion wind can be generated even at a lower voltage (that is, it is possible to reduce the size), and a stronger ion wind can be stably generated. The ion / ozone wind generating device 100, which is another form of the sterilizing / deodorizing device according to the present embodiment, that can be generated will be described in detail. This embodiment is an example, and other forms or various modifications that can be conceived by those skilled in the art also belong to the technical scope of the present embodiment (specific modifications will be described later). In addition, the embodiment and the modification example given as examples in the present specification should not be construed as being limited to being applied to specific things, and may be in any combination. For example, it should be understood that a modification example of an embodiment is a modification example of another embodiment, and even if one modification example and another modification example are described independently, there is the modification example. It should be understood that a combination of the modified example and another modified example is also described. Further, numerical values as specific examples shown in the embodiments and modifications {for example, the diameter and length / thickness of the discharge electrode and the counter electrode, the voltage difference between the discharge electrode and the counter electrode, the separation between the discharge electrode and the counter electrode It should be understood that the distance, etc. is merely an example and may be changed as appropriate as long as it does not significantly depart from the spirit of each embodiment or modification.

  A schematic structure of the ion / ozone wind generator 100 according to the present embodiment is shown in FIG. The ion / ozone wind generator 100 according to the present embodiment mainly includes one main electrode pair and six sub electrode pairs provided so as to surround the main electrode pair. As described above, the electrode pair is a set of electrodes having a discharge electrode (a needle electrode in the present embodiment) and a counter electrode, and the main electrode pair is an annular counter electrode 130a (hereinafter referred to as the counter electrode). The six counter electrode pairs have annular counter electrodes 130b to 130g (hereinafter referred to as second counter electrodes 130b to 130g, etc.) as the counter electrodes. Moreover, any counter electrode is comprised from a plate-shaped member and / or a linear member.

  Further, in the ion / ozone wind generating apparatus 100 according to the present embodiment, the first counter electrode 130a and the six second counter electrodes 130b to 130g are all in the same shape (substantially annular with the same diameter). In the ion / ozone wind generator 100 according to the present embodiment, the second counter electrodes 130b to 130g are arranged along the outer periphery of the first counter electrode 130a and adjacent to each other. As a result, a virtual circle S (a portion indicated by a broken line in FIG. B1) inscribed with the second counter electrodes 130b to 130g is formed outside the second counter electrodes 130b to 130g.

  More specifically, when assuming a substantially regular hexagonal shape, the second opposed electrodes are adjacent to each other so that the centers of the six second opposed electrodes 130b to 130g form vertices of the substantially regular hexagonal shape. Electrodes 130b to 130g are provided. In other words, in the ion / ozone wind generating apparatus 100 according to the present embodiment, the second counter electrodes 130b to 130g are arranged such that the outer peripheries of the counter electrodes adjacent to each other are in contact with each other. For example, the outer periphery of the second counter electrode 130b is in contact with the outer periphery of the second counter electrodes 130c and 130g adjacent to the second counter electrode 130b. Further, the first counter electrode 130a is further in contact with each of the second counter electrodes 130b to 130g (that is, arranged at the center of a substantially regular hexagonal shape assumed by the second counter electrodes 130b to 130g). ) Can be defined as provided. The second counter electrodes 130b to 130g do not necessarily have to be adjacent (contacted) with adjacent counter electrodes, and may be in close proximity to each other. However, if they are too far apart, The wind force generated from the generator 100 is reduced. Therefore, in each of the second counter electrodes 130b to 130g, the distance between the outer peripheries of the adjacent counter electrodes (particularly, the shortest distance) is equal to or less than the diameter of the second counter electrodes 130b to 130g (or 1 / n or less of the diameter; It is preferable that n is a natural number). Further, the first counter electrode 130a does not necessarily have to be in contact with all the second counter electrodes 130b to 130g, and may be in a close state, but is in contact with at least a part of the second counter electrodes 130b to 130g. (Even in such a case, the shortest distance between the outer peripheries is not more than the diameter of the first counter electrode 130a and the second counter electrodes 130b to 130g or 1 / n or less of the diameter; n is a natural number. Is preferred).

  In addition, the first counter electrode 130a and the second counter electrodes 130b to 130g include a needle-like electrode 120 (particularly, the needle-like electrodes 120a and 120b that serve as discharge portions in the respective counter electrodes) as a pair of discharge-side electrodes. 120g) forms a main electrode pair and a sub electrode pair. In addition, each counter electrode (1st counter electrode 130a and 2nd counter electrode 130b-130g) which concerns on this embodiment is a double annular structure as mentioned above, and it is provided so that a main ring electrode and a main ring electrode may be enclosed. The secondary annular electrode is fixed in a conductive state by a bridge. Here, the role of each of the main annular electrode, the sub-annular electrode, and the bridge in each electrode pair and the principle of generation of ion wind by the double annular electrode having these are as described above, and will be omitted. Each counter electrode (the first counter electrode 130a and the second counter electrodes 130b to 130g) is not limited to a double ring structure, but a part or all of the counter electrode is a single ring structure (or three or more layers). Or a spiral structure (a specific aspect of the spiral structure will be described later).

  Next, the action and effect of the ion / ozone wind generator 100 according to the present embodiment in generating the ion wind will be described with reference to FIG. B2. In addition, in FIG. B2, in order to make it easy to imagine the action and effect, there are cases where each counter electrode is positioned on a different plane, but each counter electrode is positioned on the same plane. However, it is supplemented that the same action and effect are brought about.

  According to the ion / ozone wind generating apparatus 100 according to the present embodiment, the first counter electrode 130a is set to the approximate center (near the center of the virtual circle S), and the second counter electrodes 130b to 130g are provided so as to surround the periphery. As a result, the ion wind generated in the main electrode pair is pushed forward by the follow-up wind of the ion wind generated in the sub electrode pair. Will be delivered to the object without being scraped (protective effect by the sub electrode pair). That is, even when each electrode pair has a smaller shape {for example, the diameter of the counter electrode is about 1 cm (preferable range is 5 mm to 5 cm), and the distance between the needle electrode and the counter electrode is about 1 to 2 cm. (The preferred range is 1 mm to 2 cm), the potential difference between the needle electrode and the counter electrode is about 3 to 100 volts}, and an ion wind having a sufficient air volume can be obtained.

  In the ion / ozone wind generating apparatus 100 according to the present embodiment, the first counter electrode 130a is surrounded by the adjacent second counter electrodes 130b to 130g (the second counter electrode as much as possible). , A configuration provided to be adjacent to the first counter electrode 130a). By adopting such a configuration, the ratio of the ionic wind generated by each electrode pair to be in contact with the ionic wind generated from the adjacent electrode pair is greater than the ratio of being in contact with the stationary outside air ( That is, the generated ionic wind is difficult to come into contact with the stationary outside air, and resistance due to friction with the outside air is reduced).

  Further, particularly, the ion wind generated at the first counter electrode 130a is surrounded by another ion wind, so that it is difficult to come into contact with the outside air, and the protection effect by the sub electrode pair is further enhanced. Will be. Thus, the ion / ozone wind generating apparatus 100 according to the present embodiment is a region where the ion wind ejected from the ion / ozone wind generating apparatus 100 comes into contact with the stationary outside air even when viewed from the entire ejected ion wind. The ionic wind at the center (ion wind generated at the main counter electrode pair) is protected by the surrounding ionic wind (ion wind generated at the sub counter electrode pair). This makes it possible to deliver a stronger ionic wind to a far object. In this way, by providing each counter electrode adjacent to each other and reducing the gap between the counter electrodes as much as possible, a larger counter electrode is provided in a limited space (or the number of counter electrodes is reduced). It is possible to generate an ionic wind having a larger air volume.

  Further, like the ion / ozone wind generating apparatus 100 according to the present embodiment, the counter electrodes (the first counter electrode 130a and the second counter electrodes 130b to 130g) are all formed in the same shape, whereby the main electrode pair and the sub electrode Each of the ion winds generated in each pair of electrodes has a large air volume to some extent (a portion having a small air volume does not occur locally). Furthermore, by making these second counter electrodes 130b to 130g have the same shape, the ion wind generated in the sub electrode pair (particularly each of the second counter electrodes 130b to 130g) has a region in contact with the outside air. Since the electrode pairs are substantially equal regardless of where the electrode pairs are installed, the local air volume unevenness in the entire ion wind is reduced. Accordingly, with such a configuration, it is possible to obtain an ion wind that is more stable and has a large air volume even when viewed with the entire ion / ozone wind generator 100.

  As shown in FIG. B1, the ion / ozone wind generating apparatus 100 according to the present embodiment makes the opposing electrodes in the main electrode pair and the sub electrode pair adjacent to each other so that they can be electrically connected (each of the needle electrodes 120a to 120a). Similarly, each of 120g can be conducted). With this configuration, each counter electrode (each needle electrode) can be made equipotential, facilitating control of the voltage in the entire sterilization / deodorizing apparatus, and stabilizing the generation of ion wind. {However, the present invention is not limited to this, and each counter electrode (each needle electrode) may not be conductive).

  In addition, according to the ion / ozone wind generating apparatus 100 according to the present embodiment, there is one needle-like electrode for one counter electrode (double annular counter electrode) (there is one-to-one correspondence). In addition, since the corona discharge can be performed by each electrode pair (ion wind can be generated by a plurality of electrode pairs), the operation stability of the entire ion / ozone wind generator 100 is maintained, Since a large air volume ion wind is obtained by each electrode pair and further combined, it is possible to stably obtain a large air volume ion wind.

  As described above, according to the ion / ozone wind generating apparatus 100 according to the present embodiment, a virtual circle in which an ion wind can be generated is assumed, and shapes adjacent or close to each other on the circumference of the virtual circle. By providing a plurality of sub electrode pairs that are electrode pairs in which the counter electrode is positioned, and by providing a main electrode pair that is an electrode pair in which the counter electrode is positioned in the circumference of the virtual circle, a stronger ion wind is obtained. It is possible to generate more stably. Here, in FIG. B1, the sizes of the annular counter electrode in the main electrode pair and the annular counter electrode in the sub electrode pair are all equal, and the six annular counter electrodes in the sub electrode pair are replaced with the annular counter electrode in the main electrode pair. However, the shape and positional relationship of each counter electrode pair is not limited to this, and there are various configurations that can exhibit the above-described effects (for example, the protective effect by the sub electrode pair). A simple configuration is conceivable.

  For example, as shown in FIG. B3, the annular counter electrode in the sub electrode pair has a smaller diameter (ring diameter) than the annular counter electrode in the main electrode pair, and circumscribes the annular counter electrode in the main electrode pair. May be arranged (so that the respective annular counter electrodes are adjacent to each other).

  On the other hand, as shown in FIG. B4, the sub-electrode is formed so that the annular counter electrode in the sub-electrode pair has a larger diameter (ring diameter) than the annular counter-electrode in the main electrode pair and circumscribes the annular counter-electrode in the main electrode pair. You may arrange | position the cyclic | annular counter electrode in a pair (so that each cyclic | annular counter electrode may adjoin).

  As shown in FIG. B5, the annular counter electrodes in the plurality of sub electrode pairs do not have to have the same shape. The ring counter electrodes in some of the sub electrode pairs have a large diameter (ring diameter), and another sub electrode pair has another sub electrode pair. The annular counter electrode in the electrode pair may have a smaller diameter (ring diameter).

  Further, as shown in FIG. B6, the annular counter electrode in the main electrode pair and the annular counter electrode in the sub electrode pair are not on the same plane (a plane including the annular counter electrode in the main electrode pair), but different. It is good also as a structure distribute | arranged on the plane {For example, in FIG. B6, it arrange | positions so that the main electrode pair may become the front side (ion-air blowing direction side) rather than the sub electrode pair}.

  Furthermore, as shown in FIG. B7, the number of main electrode pairs is not limited to one, and a plurality of main electrode pairs may be provided (for example, three first counter electrodes 130a are provided in FIG. B6).

  Here, as shown in FIG. B8, the counter electrode in the main electrode pair and / or the sub electrode pair is not limited to a polygonal shape, a circular shape, and a substantially circular shape, but is a spiral shape (the number of turns and the winding width are It may be an example only). Here, the difference between the spiral shape as shown in FIG. B8 (a) and the spiral shape as shown in FIG. B8 (b) is the presence or absence of the end point of the spiral when the spiral shape is formed toward the center. . In particular, when each counter electrode has a spiral shape as shown in FIG. B8 (b), there is an advantage that it is easy to conduct the counter electrodes. When the counter electrode has such a spiral shape, there is a concern that unevenness may occur in the corona discharge as compared with the case of the multi-ring structure. However, as the counter electrode itself becomes smaller, (For example, the diameter of the counter electrode is about 1 cm), and the distance error (peeling from the multiple ring structure) between each part of the spiral lead wire that causes the unevenness and the needle-like electrode is small, so it is equivalent to the multiple ring structure It will be supplemented that the effect of can be easily obtained.

  As shown in FIG. B9, the discharge-side electrode (for example, a needle-like electrode) is an annular discharge electrode 120 {FIG. B9 (b)}, or simply an annular discharge electrode 120 in which the needle-like electrode is bridged in an annular shape. It is good also as {FIG. B9 (a)}.

  The negative ion / ozone generator is inevitable to be downsized (portable) = small wind of ion wind, so the wind of ion wind generated by corona discharge is delivered to the target without being cut as much as possible. Some kind of ingenuity is important for commercialization. However, as long as aiming for miniaturization (portability), it is desirable to devise an electrode configuration that is an essential configuration of the negative ion / ozone generator without providing an additional device such as a blower or a boost converter. According to this embodiment, even if the negative ion / ozone generator is downsized (portable), a means for generating an ion wind well can be provided.

<< Second Embodiment >>
According to the ion / ozone wind generator 100 described above, an ion wind having a sufficient air volume can be obtained, but there is room for further improvement in that the generated ion wind is substantially unidirectional {specifically Since the generated ionic wind is directed in a specific direction, for example, when the above-described ion / ozone wind generator 100 is installed in an arbitrary place in a sealed room, the generated ionic wind is There was a possibility that the entire room would not be effectively spread (the ion / ozone molecule circulates in a sealed room due to the strong ionic wind generated, but the circulation efficiency is low)}. Therefore, as compared with the ion / ozone wind generator 100 described above, the ion / ozone wind generator 100, which is another form of the sterilizer / deodorizer, capable of generating ion wind in a wider range. This will be described in detail as a second embodiment. The illustration shown in the second embodiment is merely an example, and specific modifications belonging to the technical scope of the present embodiment will be described later in the third embodiment. In addition, the embodiment and the modification example given as examples in the present specification should not be construed as being limited to being applied to specific things, and may be in any combination. For example, it should be understood that a modification example of an embodiment is a modification example of another embodiment, and even if one modification example and another modification example are described independently, there is the modification example. It should be understood that a combination of the modified example and another modified example is also described. Further, numerical values as specific examples shown in the embodiments and modifications {for example, the diameter and length / thickness of the discharge electrode and the counter electrode, the voltage difference between the discharge electrode and the counter electrode, the separation between the discharge electrode and the counter electrode It should be understood that the distance, etc. is merely an example and may be changed as appropriate as long as it does not significantly depart from the spirit of each embodiment or modification.

  First, after describing the outline of the ion / ozone wind generator according to the second embodiment, the outline of the third embodiment, which is another form of the second embodiment, will be described.

  As an example of the electrode pair 310 included in the ion / ozone wind generator 100-3 according to the second embodiment, as shown in FIGS. C1 and C2, a discharge electrode 320 having a linear discharge portion (discharge line) 321; , Electrode pair 310 composed of a counter electrode 330 having a linear power receiving unit (receiving wire) 331 (electrode pair, discharge electrode, discharge unit, discharge wire, discharge point, counter electrode, power receiving unit, power receiving wire, Details of the power receiving point will be described later). More specifically, the discharge unit 321 and the power reception unit 331 are annular, the power reception unit 331 has a larger diameter than the discharge unit 321, and the power reception unit 331 is arranged in a plane parallel to the plane where the discharge unit 321 is arranged. It is configured to be.

  In the electrode pair 310 according to FIG. C1, since the discharge unit 321 and the power reception unit 331 are arranged in the same circle, a corona discharge is generated substantially uniformly between the discharge unit 321 and the power reception unit 331. It is configured as follows. On the other hand, the electrode pair 310 according to FIG. C2 has a shape in which the discharge portion 321 has a protrusion (spin) on the outer periphery of the circle, and is configured so that corona discharge is likely to occur intensively at the tip of the protrusion. The discharge electrode 320 (discharge part 321) according to FIG. C1 and the discharge electrode 320 (discharge part 321) according to FIG. C2 have the same shape, and the outer periphery of the discharge electrode 320 (discharge part 321) is both edge-shaped. (A shape that forms an acute angle toward the power receiving unit 331).

  The electrode pair 310 generates a potential difference between the discharge points 322 scattered on the discharge part (discharge line) 321 and the power reception points 332 scattered on the power reception part (received wire) 331. Thus, it is configured to simultaneously generate ions, ozone, and ion wind by corona discharge at multiple points. That is, when the electrode pair 310 as shown in FIG. C1 and FIG. C2 generates ions, ozone, and ion wind by corona discharge simultaneously at multiple points, the electrode pair 310 spans 360 degrees around the power receiving unit (receiving wire) 331. The ionic wind will be scattered over a wide area. Therefore, for example, the electrode pair 310 is sized to fit in the palm (the maximum diameter is about 10 to 20 cm), and is provided in the center of the ceiling of a square six-mat room, so that ion wind is scattered throughout the room. It is possible to remove (deodorize and disinfect) malodorous components staying in the room by the oxidizing power of ozone contained in the scattered ion wind. When the discharge unit 321 and the power reception unit 331 in the electrode pair 310 are reversed (when the discharge unit 321 is located outside the power reception unit 331), the electrode pair 310 faces the center of the power reception unit (received wire) 331. Therefore, for example, the electrode pair 310 is sized to fit in the palm of the hand (the maximum diameter is about 10 to 20 cm), and is provided at the opening of the trash can. It is possible to prevent the malodorous component from leaking out.

  The ion / ozone wind generator according to the present embodiment has, as its basic concept, a discharge electrode that becomes a discharge part (discharge wire) 321 and a counter electrode that becomes a power reception part (received wire) 331. The airflow generated in accordance with the flow direction (vector) of ions generated during discharge with an electrode pair is an ion wind. In the present invention, the negative pressure generated by the airflow and the negative pressure are generated. We are also paying attention to the effect of increasing the ionic wind due to the intake flow of outside air into the open space. That is, when a corona discharge occurs between the inner peripheral edge portion of the annular counter electrode and the discharge electrode existing on the inner peripheral side of the counter electrode, the ion wind generated in the vicinity of the inner peripheral edge portion. Is discharged to the side of the annular counter electrode that does not face the discharge electrode, and at that time, a negative pressure is generated on the outer peripheral side of the annular portion of the counter electrode (the side that does not face the discharge electrode). Then, toward the space where the negative pressure is generated, the outside air surrounding the outer periphery of the counter electrode is sucked, and the ion wind pushed out to the side of the annular counter electrode not facing the discharge electrode by the sucked outside air. The wind power will increase.

  Next, FIG. C3 is a conceptual cross-sectional view showing a specific usage example of the ion / ozone wind generator 100-3 according to FIG. C1 or the ion / ozone wind generator 100-3 according to FIG. C2. The ion / ozone wind generator 100-3 according to FIG. C3 has one discharge electrode 320 and four counter electrodes 330 according to FIG. C1 or C2. The ion / ozone wind generator 100-3 according to FIG. C3 is configured to be fixed to the ceiling 400 by a fixing member 380 and to be supplied with electric power from the ceiling 400. The cover unit 350 serves as a guide member for guiding the ion wind generated from the counter electrode 330 and also serves to protect the ion / ozone wind generator 100-3. Further, the cover unit 350 has an intake port in the lower opening, and the generated ion wind can be increased by intake from the intake port.

  Here, in the ion / ozone wind generating apparatus 100-3 according to FIG. C3, the four counter electrodes 330A to 330D (power receiving units 331A to 331D) have the same shape and inner diameter, and are substantially parallel to different planes. Is arranged. Therefore, the power receiving points (power receiving points 332B and 332C) of the counter electrode {the counter electrode 330B (power receiving unit 331B) and the counter electrode 330C (power receiving unit 331C)} disposed at a position close to one discharge electrode 320 (discharge unit 321). ) Is one discharge electrode than the power receiving points (power receiving point 332A, power receiving point 332D) in the counter electrode {counter electrode 330A (power receiving unit 331A), counter electrode 330D (power receiving unit 331D)} arranged at a distant position. The distance from the discharge point 322 in 320 (discharge part 321) becomes short. Therefore, the generation rate of corona discharge between this one discharge electrode 320 (discharge part 321) and the counter electrode {counter electrode 330B (power receiving part 331B), counter electrode 330C (power receiving part 331C)} is the largest, The wind of ion wind generated from the counter electrodes 330B and 330C is the largest. The generation rate of corona discharge between this one discharge electrode 320 (discharge part 321) and the other counter electrode {counter electrode 330A (power receiving part 331A), counter electrode 330D (power receiving part 331D)} is relative. The wind force of the ion wind generated from the counter electrode 330A and the counter electrode 330D is also relatively weak. With this configuration, the ion wind generated by the counter electrode 330B and the counter electrode 330C is boosted by the tail wind of the ion wind generated by the counter electrode 330A and the counter electrode 330D. Is pushed out to the side not facing the discharge electrode 320. From this, even if the electrode pair 310 according to FIG. C3 is downsized, there is an effect that the wind force of the ion wind generated by the corona discharge spreads over a wide range without being cut as much as possible. In FIG. C3, the counter electrode 330 is not arranged on the same plane as the discharge electrode 320, but the counter electrode 330 may be arranged on the same plane.

  Next, FIG. C4 is a conceptual cross-sectional view showing a usage example that is different from FIG. C3 of the ion / ozone wind generator 100-3 according to FIG. C1 or the ion / ozone wind generator 100-3 according to FIG. C2. It is. The difference from the ion / ozone wind generator 100-3 according to FIG. C3 is that the inner diameters of the four counter electrodes 330A to 330D (power receiving units 331A to 331D) are not uniform, and FIG. In the case of the ion / ozone wind generator 100-3, the distance between the discharge point 322 and each of the power reception points (332A to 332D) is a uniform distance. By comprising in this way, the ion wind of the substantially the same air volume generate | occur | produces from each receiving point (332A-332D), and the ion wind over a three-dimensional and wide range can be generated. In FIG. C4 as well, similarly to FIG. C3, the discharge electrode 320 and the counter electrode 330 may be arranged on the same plane.

  As described above, the ion / ozone wind generator according to the second embodiment and the third embodiment to be described later is the first concept in that it has an electrode pair having a discharge electrode and a counter electrode. Although it is the same as that of embodiment, a discharge electrode is made into a linear discharge part (discharge wire), and a counter electrode is also made into a linear power receiving part (received electric wire). That is, a potential difference is generated between the discharge points scattered on the discharge part (discharge line) and the power reception points scattered on the power reception part (received wire), and coronas are simultaneously generated at multiple points. Ion, ozone and ion wind are generated by the discharge. In addition, as described above, the ion wind generally causes collisions with air molecules while ions emitted from the discharge point during corona discharge migrate toward the power reception point, so that the power reception point from the discharge point. It is said that the air flow is generated toward That is, the air flow generated according to the flow direction (vector) of ions generated during discharge is an ion wind. In the present invention, the negative pressure generated by the air flow and the space where the negative pressure is generated are generated. We are also paying attention to the effect of increasing ion wind by the intake air flow of outside air. For example, as apparent from the location where the ion wind is generated as shown in FIG. A1, when corona discharge occurs at the inner peripheral edge portion of the annular counter electrode, the ion wind flows from the vicinity of the inner peripheral edge portion toward the front surface (needle). In that case, a negative pressure is generated on the back side of the annular portion of the counter electrode (the surface not facing the needle electrode). Then, the outside air surrounding the outer periphery of the counter electrode is sucked toward the space where the negative pressure is generated, and the wind force of the ion wind pushed out toward the front surface by the sucked outside air increases. This is because a potential difference is generated between the discharge points scattered on the discharge part (discharge line) and the power reception points scattered on the power reception part (received wire), and ions and ions are generated by corona discharge. The same applies to the case where ozone and ionic wind are generated, and the ionic wind increased by the negative pressure is generated in the open portion of the power receiving portion (receiving wire) on the side not facing the discharge portion (discharge line). It becomes. The detailed structure of the ion / ozone wind generator according to the second embodiment based on such a basic concept will be described below.

  First, the schematic structure of the ion / ozone wind generator 100-2 according to the second embodiment is shown in FIG. C5. C5 (a) is a conceptual front view of the electrode pair 310 of the device, and FIG. C5 (b) is a conceptual side view of the electrode pair 310. The ion / ozone wind generator 100-2 according to the second embodiment includes a pair of electrode pairs each having a discharge electrode (annular electrode in the present embodiment) and a counter electrode (annular electrode in the present embodiment). Here, the counter electrode and the discharge electrode (especially the discharge electrode) are perforated so that the outer periphery of the disk-shaped electrode remains, as well as a linear member (however, the linear electrode is shaped so as to surround the ring electrode). The electrode pair 310 is composed of a linear and annular discharge electrode 320 and a linear and annular counter electrode 330. In addition, when the discharge electrode 320 is linear, the discharge portion 321 that is the outer peripheral edge of the return of the discharge electrode 320 (return edge on the side facing the counter electrode 330) is also linear, and hence the discharge electrode is hereinafter referred to. 320 and the discharge portion 321 may be described as the same member (that is, the members are the same, but a portion where discharge is generated in particular is referred to as the discharge portion 321). Similarly, when the counter electrode 330 is linear, the counter electrode 330 and the power receiving unit 331 may be described as the same member (in this case, although the members are the same, in particular, the power reception is not performed). The portion where the power is generated is referred to as a power receiving unit 331). Here, in this example, the counter electrode 330 (power receiving unit 331) and the discharge electrode 320 (discharge unit 321) in the electrode pair 310 are arranged on substantially the same plane, and the counter electrode 330 (power receiving unit 331) and The discharge electrode 320 (discharge part 321) is configured such that the circumference of the discharge electrode 320 (discharge part 321) is smaller. Moreover, in this example, the discharge electrode 320 (discharge part 321) and the counter electrode 330 (power receiving part 331) are similar and are arranged concentrically, so that the discharge point in the discharge electrode 320 (discharge part 321). Since the distance between 322 and the power receiving point 332 (the power receiving point at the shortest distance from the discharge point 322) in the counter electrode 330 (power receiving unit 331) is substantially the same at any location, the discharge unevenness is reduced. ing.

  With this configuration, when a potential difference is generated between the discharge electrode 320 (discharge unit 321) and the counter electrode 330 (power reception unit 331), the outer periphery of the counter electrode 330 (power reception unit 331) {discharge electrode 320 ( The ion wind can be generated in all directions (360 degree direction) in the open portion on the side not facing the discharge portion 321) (the lightning line in the figure is an image of corona discharge, the ion wind in which a thick arrow line is generated) It is an image diagram regarding the generation direction in a part). Note that the discharge electrode 320 (discharge part 321) and the counter electrode 330 (power reception part 331) according to this example are provided with the counter electrode 330 (power reception part 331) for convenience of explanation in FIG. Although it is illustrated that a distance between the plane and the plane on which the discharge electrode 320 (discharge section 321) exists is provided (separated), the counter electrode 330 (power receiving section 331) and the discharge electrode 320 (discharge) are actually illustrated. Part 321) is preferably present on the same plane {ie, the counter electrode 330 (power receiving part 331) and the discharge electrode 320 (discharge part 321) are present on substantially the same plane. It is possible to create such an effect, but maximize the discharge efficiency = minimize the distance from the discharge point 322 in the discharge electrode 320 (discharge part 321) to the power reception point 332 in the counter electrode 330 (power reception part 331). In terms, it is meant that it is desirable to place on the same plane counter electrode 330 (the power receiving unit 331) and the discharge electrode 320 (discharge portion 321)}.

  In this example, the counter electrode 330 (power receiving unit 331) is provided outside the return of the discharge electrode 320 (discharge unit 321). However, the discharge electrode 320 (power receiving unit 331) is provided outside the return of the counter electrode 330 (power receiving unit 331). The discharge unit 321) may be provided (that is, both arrangements may be reversed). In such a configuration, an ion wind is generated toward the inner center direction of the return of the counter electrode 330 (the power receiving unit 331). That is, in the case where ion wind is generated in all directions (360-degree direction) in the outer periphery of the counter electrode 330 (power receiving unit 331) {the open portion on the side not facing the discharge electrode 320 (discharge unit 321)} It is also possible to aggregate the ion wind. This supplements that the same can be said for all configurations exemplified in the second embodiment and the third embodiment described later.

  Next, FIG. C6 has illustrated an example at the time of use and cleaning of the ion ozone wind generator 100-2 which concerns on 2nd Embodiment. When the ion / ozone wind generator 100-2 according to the second embodiment is used, the ion / ozone wind generator 100-2 is mounted on the ceiling 400 (for example, in a rectangular six-tatami room, as shown in FIG. C6 (a)). Install it near the center of the ceiling. The attachment method is not particularly limited, and there is no problem as long as the ion / ozone wind generator 100-2 is fixed to the ceiling 400 (for example, a well-known method such as assembly with a screw may be used). In this example, the cover unit 350 is configured to cover the electrode pair 310 of the ion / ozone wind generator 100-2, and the cover unit 350 is fixed to the ceiling 400 when installed on the ceiling 400. The cover member 360 is a cover member 360 and the cover member 360 is a cover member 370. Further, a jet outlet 340 is provided between the cover member 360 and the lid member 370, and the ion wind generated from the electrode pair 310 is jetted from the jet outlet 340 to the outside of the ion / ozone wind generator 100-2. Will be. The shape of the ejection port 340 may be any shape as long as the generated ion wind can pass therethrough. For example, the ejection port 340 may have a slit shape or a shape in which a hole is formed by hollowing the cover unit 350.

  Then, when cleaning the ion / ozone wind generator 100-2 according to the second embodiment, the lid member 370 is removed from the cover member 360 as shown in FIG. C6 (b). As shown in the figure, the cover member 360 and the discharge electrode 320 (discharge part 321) are fixed, and the cover member 370 and the counter electrode 330 (power receiving part 331) are fixed. Then, the lid member 370 and the counter electrode 330 (power receiving unit 331) can be removed from the ion / ozone wind generator 100-2 at the same time, and the counter electrode 330 (power receiving unit 331) or ceiling to which dirt easily adheres can be removed. The area around 400 can be easily cleaned. In addition, the usage method and installation location of the ion / ozone wind generator 100-2 are not limited to this. For example, the ion / ozone wind generator 100-2 may be used on a desk or hung on a wall {in that case, The inner diameters of the discharge electrode 320 (discharge part 321) and the counter electrode 330 (power reception part 331) may be changed as appropriate depending on the application}.

  The above is an example of the ion / ozone wind generator 100-2 according to the second embodiment, but the shape, number, and positional relationship of the discharge electrode and the counter electrode are not limited thereto, and the ion wind is generated in a wide range. Various configurations are possible as possible configurations. Therefore, an example of such various configurations will be shown below.

  First, the discharge electrode 320 and the counter electrode 330 (power reception unit 331) according to the second embodiment may be polygonal, for example, a triangle as shown in FIG. C7. FIG. C7 (a) is a conceptual front view of the electrode pair 310 of the device, and FIG. C7 (b) is a conceptual side view of the electrode pair 310 of the device. As shown in the figure, even if the electrode pair 310 has a triangular shape, substantially uniform discharge is performed on each side of the triangle, so that an ion wind can be generated over the entire circumference (see FIG. The lightning line in the middle is an image of corona discharge, and the thick arrow line is an image of the generation direction of a part of the ion wind). In this example, the discharge electrode 320 (discharge part 321) and the counter electrode 330 (power reception part 331) are triangular, but may be a polygon that is equal to or greater than a triangle. The shape may have a concavo-convex shape, or the concavo-convex shape may be wavy. However, if the discharge electrode 320 (the discharge part 321) is a triangle, the number of vertices of the discharge electrode 320 (the discharge part 321) and the counter electrode 330 (the power reception part 331) is such that the counter electrode 330 (the power reception part 331) is also a triangle. Are preferably the same, and the discharge electrode 320 (discharge part 321) and the counter electrode 330 (power reception part 331) are more preferably similar. In addition, when the discharge electrode 320 (discharge part 321) and the counter electrode 330 are similar, the center of gravity of the ring of the discharge electrode 320 (discharge part 321) and the center of gravity of the return of the counter electrode 330 (power reception part 331) It is preferable that the position substantially coincides. With such a configuration, the distance between the electrodes (especially, the distance between the discharge point 322 and the power reception point 332) can be made uniform, so that discharge unevenness is less likely to occur (the ion wind over the entire circumference). Can be generated). In addition, when the discharge electrode 320 (discharge part 321) and the counter electrode 330 (power receiving part 331) are polygonal, by increasing the number of sides, the distance between each other (in particular, the discharge point 322 and the power receiving point 332). ) Is more uniform and discharge unevenness is less likely to occur (for this reason, the electrode shape is particularly preferably circular).

  As shown in FIG. C8, the discharge part 321 (360 degrees outside the discharge electrode 320) of the ion / ozone wind generator 100-2 according to the second embodiment has fine irregularities on the discharge part 321 that is the edge part. (For example, a shape having many irregularities such as a shape like a saw blade). Even in such a configuration, since discharge occurs between the convex portion (discharge point 322) of the discharge portion 321 and the power reception portion 331 (power reception point 332), the discharge portion 321 does not provide the fine unevenness. Similarly, the structure in which fine irregularities are provided in the discharge part 321 within the range where a substantially uniform ion wind can be generated, and the structure in which fine irregularities are not provided in the discharge part 321 Meaning that they can be considered the same).

  As shown in FIG. C9, the discharge electrode 320 and the counter electrode 330 of the ion / ozone wind generator 100-2 according to the second embodiment may have a plate shape. By comprising in this way, the intensity | strength of the discharge electrode 320 and the counter electrode 330 can go up, and it can make it hard to break. On the other hand, in particular, the shape of the discharge electrode 320 is not a plate shape but an annular shape (for example, a linear electrode constituted only by the discharge part 321 or a shape in which the outer periphery of the discharge electrode 320 shown in FIG. Since the opening of the ring serves as an intake port, a stronger ion wind can be generated. Note that the shapes of the discharge electrode 320 and the counter electrode 330 are not limited to this, and one may be plate-shaped and the other may be linear (that is, the discharge unit 321 and the power reception unit 331 exist). As long as it is).

  Next, a plurality of discharge electrodes 320 and / or counter electrodes 330 may be provided in the ion / ozone wind generator 100-2 according to the second embodiment. For example, as shown in FIG. 1 unit 321) and three counter electrodes 330 (power receiving unit 331) {counter electrode 330a (power receiving unit 331a), counter electrode 330b (power receiving unit 331b), counter electrode 330c (power receiving unit 331c)}. . As shown in FIG. C11, when three counter electrodes are provided, one discharge electrode 320 (discharge unit 321) and each counter electrode {counter electrode 330a (power receiving unit 331a), counter electrode 330b (power receiving) Portion 331b) and counter electrode 330c (power receiving portion 331c)} are arranged in multiple layers as shown in the figure to generate a potential difference, and simultaneously from each counter electrode 330 (counter electrode 330a, counter electrode 330b, counter electrode 330c). An ion wind is generated (the lightning line in the figure is an image of corona discharge, and a thick arrow line is an image of the generation direction in a part of the ion wind). That is, at the discharge point 322 and each counter electrode {counter electrode 330a (power receiving unit 331a), counter electrode 330b (power receiving unit 331b), counter electrode 330c (power receiving unit 331c)} in one discharge electrode 320 (discharge unit 321)}. Corona discharge occurs simultaneously with each power receiving point (power receiving point 332a, power receiving point 332b, power receiving point 332c) that is the power receiving point and is the shortest distance from the discharge point 322.

  Here, in this example, since the three counter electrodes 330a to 330c (power receiving units 331a to 331c) have the same shape and inner diameter, they are arranged in substantially the same plane as one discharge electrode 320 (discharge unit 321). The power receiving point (power receiving point 332a) of the counter electrode {counter electrode 330a (power receiving unit 331a)} is the power receiving point of the other counter electrode {counter electrode 330b (power receiving unit 331b), counter electrode 330c (power receiving unit 331c)}. The distance from the discharge point 322 in one discharge electrode 320 (discharge part 321) is shorter than the point (power reception point 332b, power reception point 332c). Therefore, the generation ratio of corona discharge between the one discharge electrode 320 (discharge part 321) and the counter electrode 330a (power receiving part 331a) is the largest, and the wind of ion wind generated from the counter electrode 330a is the largest. Become. The generation rate of corona discharge between the one discharge electrode 320 (discharge part 321), the counter electrode 330b (power receiving part 331b) and the counter electrode 330c (power receiving part 331c) is relatively low, and the counter electrode The wind force of the ion wind generated from 330b and the counter electrode 330c is also relatively weak. Therefore, by configuring in this way, the ion wind generated by the counter electrode 330a is pushed to the front surface by the tail wind of the ion wind generated by the counter electrode 330b and the counter electrode 330c. Is as described above in the present embodiment). From this, even if the electrode pair shown in this example is downsized, it can be said that the wind force of the ion wind generated by the corona discharge reaches the wide range without being cut as much as possible.

  Note that the three counter electrodes of the counter electrodes 330a to 330c need not have the same shape. For example, by increasing the counter electrode 330a (the diameter of the power receiving unit) and making the counter electrode 330b and the counter electrode 330c (the diameter of the power receiving unit) smaller than that, the discharge unit and each counter electrode in one discharge electrode 320 The distance to the power receiving unit may be uniform. In the case of such a configuration, an ion wind having the same air volume is generated from each counter electrode (thus, an ion wind can be generated in three dimensions and over a wide range).

  Further, in the ion / ozone wind generating apparatus 100-2 according to the second embodiment, a plurality of discharge electrodes 320 may be provided instead of one. For example, as shown in FIG. Three discharge parts 321) {discharge electrode 320a (discharge part 321a), discharge electrode 320b (discharge part 321b), discharge electrode 320c (discharge part 321c)}, three counter electrodes 330 (power receiving part 331) {counter electrode 330a (power receiving unit 331a), counter electrode 330b (power receiving unit 331b), counter electrode 330c (power receiving unit 331c)} may be provided, in which case the discharge electrode and the counter electrode are staggered as illustrated. (In the illustration of the same figure, the aspect which provides one discharge electrode in the intermediate | middle layer between counter electrodes can be illustrated). With such a configuration, even if a corona discharge does not occur due to contamination on a certain discharge electrode or counter electrode, a corona discharge of a discharge electrode or counter electrode other than the certain discharge electrode or counter electrode Therefore, an ionic wind can be generated.

  In the above description, the shapes of the discharge electrode 320 and the counter electrode 330 according to the second embodiment are not limited to polygons and circles, and may be any ring shape (for example, a star shape). Also has the same effect). In addition, the annular shape of the discharge electrode 320 may be a flat plate shape. However, since the annular shape plays a role of an intake port, the discharge electrode 320 has a shape having a hole in the flat plate or a linear member (for example, a wire). It is preferable that the shape is a ring-like shape. In addition, it is preferable that the shape of the discharge part 321 (the edge of the discharge part) of the annular discharge electrode 320 is an acute angle in terms of reducing discharge unevenness.

«Third embodiment»
In addition, although the shape of the discharge electrode 320 and the counter electrode 330 which concerns on 2nd Embodiment was comprised so that it might become cyclic | annular, it is not limited to this, For example, the discharge electrode 320 and the counter electrode 330 which concern on 2nd Embodiment A part of the shape may be cut by two half straight lines that pass through the center of gravity (the center of gravity where the discharge electrode 320 and the counter electrode 330 substantially coincide). Therefore, such a configuration will be described in detail as a third embodiment of an ion / ozone wind generator 100-3, which is another embodiment of the sterilizing / deodorizing apparatus according to the present embodiment. In the third embodiment, the basic concept is that the discharge electrode is a linear discharge part (discharge line) and the counter electrode is also a linear power receiving part (received wire). This is the same as in the second embodiment.

  First, as shown in FIG. C13, the discharge electrode 320 (discharge part 321) and the counter electrode 330 (power reception part 331) according to the third embodiment have two circular shapes shown in FIG. {I.e., the discharge electrode 320 (discharge part 321) and the counter electrode 330 (power reception part 331) are arcs of a quarter of the circle shown in FIG. C5. Is}. Fig. C13 (a) is a conceptual front view of the electrode pair 310 of the ion / ozone wind generating apparatus 100-3 according to the third embodiment, and Fig. C13 (b) is an ion / ozone wind according to the third embodiment. It is a conceptual side view of the electrode pair 310 of the generator 100-3. By comprising in this way, the range which ion wind generate | occur | produces becomes narrow compared with the ion ozone wind generator 100-2 which concerns on 2nd Embodiment (in this example, 90 degree | times), but a shape can be made smaller. In addition, as described later, it is suitable for a usage method or installation method (use method or installation method different from the ion / ozone wind generator 100-2 according to the second embodiment) such as use in a corner of a room. The shape of the ion / ozone wind generator 100-3 according to the third embodiment is the same as that of the ion / ozone wind generator 100-2 (annular) according to the second embodiment with two half straight lines passing through the center of gravity. The cut-out shape may be used, and the cut-out range (size and angle) is no problem in any way (for example, half of a circle, one-eighth, etc.), and matches the method of use (installation location). May be changed as appropriate.

  Next, FIG. C14 has illustrated an example at the time of use of the ion ozone wind generator 100-3 which concerns on 3rd Embodiment. Note that FIG. C14 (a) is a top view of the ion / ozone wind generator 100-3 according to the third embodiment. When using the ion / ozone wind generator 100-3 according to the third embodiment, as shown in FIG. C14 (a), the ion / ozone wind generator 100-3 is attached to the wall 500 (for example, a rectangular six-tatami room). Install near the ceiling). As shown in the figure, the shape of the electrode pair 310 is cut from a ring shape to a quarter of two half lines passing through the center of gravity, so that it is installed at the four corners of the room. The shape is suitable for. Further, by installing at the four corners of the room, a strong ion wind can be spread throughout the room even if the shape of the discharge electrode 320 (discharge part 321) and the counter electrode 330 (power reception part 331) is not circular. . Further, by forming the discharge electrode 320 and the counter electrode 330 in a curved shape, a uniform ion wind can be generated in a wider range (the generation direction in a part of the ion wind in which a thick arrow line in the figure is generated). Is an image diagram). FIG. 14B is a side view of the ion / ozone wind generator 100-3 according to the third embodiment. Similarly to the ion / ozone wind generator 100-2 according to the second embodiment, the ion / ozone wind generator 100-3 according to the third embodiment is provided with a jet nozzle 340, and the jet nozzle 340 Ion wind will be ejected to the outside of the ion / ozone wind generator 100-3 (thick arrow line in the figure is an image diagram relating to the generation direction of a part of the ion wind). The method for attaching the ion / ozone wind generator 100-3 is not particularly limited. For example, the ion / ozone wind generator 100-3 may be fixed to the ceiling 400 or the wall 500 as shown in FIG. C14 (b). Further, the ion / ozone wind generator 100-3 is configured in such a form that the cover unit 350 covers the electrode pair 310. The cover unit 350 includes a cover member 360 that is fixed to the ceiling 400 and the wall 500 when installed on the ceiling 400 and the wall 500, and a lid member 370 that serves as a lid of the cover member 360. Further, a jet outlet 340 is provided between the cover member 360 and the lid member 370, and the ion wind generated from the electrode pair 310 is jetted from the jet outlet 340 to the outside of the ion / ozone wind generator 100-3. Will be. The shape of the ejection port 340 may be any shape as long as the generated ion wind can pass therethrough. For example, the ejection port 340 may have a slit shape or a shape in which a hole is formed by hollowing the cover unit 350.

  Note that a plurality of discharge electrodes 320 and / or counter electrodes 330 in the ion / ozone wind generator 100-3 according to the third embodiment may be provided. For example, as shown in FIG. 321) and three counter electrodes 330 (power receiving unit 331) {counter electrode 330a (power receiving unit 331a), counter electrode 330b (power receiving unit 331b), counter electrode 330c (power receiving unit 331c)} may be provided. In addition, as shown in FIG. C16, when three counter electrodes are provided, one discharge electrode 320 (discharge unit 321) and each counter electrode {counter electrode 330a (power receiving unit 331a), counter electrode 330b (power receiving) Portion 331b) and the counter electrode 330c (power receiving unit 331c)}, a potential difference is generated between the counter electrode 330 {the counter electrode 330a (power receiving unit 331a), the counter electrode 330b (power receiving unit 331b), and the counter electrode 330c. (Power receiving unit 331c)} simultaneously generates ion wind (the lightning line in the figure is an image diagram of corona discharge, and a thick arrow line is an image diagram regarding the generation direction in a part of the ion wind). That is, at the discharge point 322 and each counter electrode {counter electrode 330a (power receiving unit 331a), counter electrode 330b (power receiving unit 331b), counter electrode 330c (power receiving unit 331c)} in one discharge electrode 320 (discharge unit 321)}. Corona discharge occurs simultaneously with each power receiving point (power receiving point 332a, power receiving point 332b, power receiving point 332c) that is the power receiving point and is the shortest distance from the discharge point 322.

  Here, in this example, since the three counter electrodes 330a to 330c (power receiving units 331a to 331c) have the same shape and inner diameter, one discharge electrode 320 (discharge) is similar to the electrode pair 310 of FIG. Portion 321) and the counter electrode 330a (power receiving unit 331a) have the largest corona discharge generation rate, and the ion wind generated from the counter electrode 330a (power receiving unit 331a) has the largest wind force. The generation rate of corona discharge between the one discharge electrode 320 (discharge part 321), the counter electrode 330b (power receiving part 331b) and the counter electrode 330c (power receiving part 331c) is relatively low, and the counter electrode The wind force of the ion wind generated from 330b (power reception unit 331b) and the counter electrode 330c (power reception unit 331c) is also relatively weak. Therefore, with this configuration, the ions generated by the counter electrode 330a (power receiving unit 331a) by the tail wind of the ion wind generated by the counter electrode 330b (power receiving unit 331b) and the counter electrode 330c (power receiving unit 331c). The wind is pushed forward to the front (this effect is as described above). From this, even if the annular electrode pair shown in the second embodiment is miniaturized, the wind force of the ion wind generated by corona discharge spreads over a wide range as much as possible by devising the installation location. It can be said that there is an effect.

  Note that, in the ion / ozone wind generating apparatus 100-3 according to the third embodiment, the three counter electrodes 330a to 330c do not have to have the same shape as in the second embodiment described above. The effect similar to the ion ozone wind generator 100-2 which concerns on a form will be acquired.

  Further, in the ion / ozone wind generating apparatus 100-3 according to the third embodiment, a plurality of discharge electrodes 320 may be provided instead of one. For example, as shown in FIG. Three discharge parts 321) {discharge electrode 320a (discharge part 321a), discharge electrode 320b (discharge part 321b), discharge electrode 320c (discharge part 321c)}, three counter electrodes 330 (power receiving part 331) {counter electrode 330a (power receiving unit 331a), counter electrode 330b (power receiving unit 331b), counter electrode 330c (power receiving unit 331c)} may be provided. With such a configuration, even if the corona discharge does not occur due to contamination on a certain discharge electrode or the counter electrode, like the ion / ozone wind generator 100-2 according to the second embodiment. An ion wind can be generated by corona discharge of a discharge electrode or counter electrode other than the certain discharge electrode or counter electrode.

  As described above, according to the ion / ozone wind generator 100-3 according to the third embodiment, the range in which the ion wind is generated is narrower than that of the ion / ozone wind generator 100-2 according to the second embodiment. It is suitable for the case where the ion wind is generated only in a specific range (necessary range) or in a specific place.

  As described above, according to the ion / ozone wind generator according to the second and third embodiments, the following effects can be obtained.

  That is, according to the ion / ozone wind generator according to the present embodiment, a discharge wire having a continuous discharge point and a receiving wire having a continuous power reception point are provided, By generating a corona discharge toward the receiving line, it is possible to generate an ion / ozone wind in a wide range and an ion wind containing ion and ozone on the side of the receiving line that does not face the discharge line. it can.

  According to the ion / ozone wind generating apparatus according to the present embodiment, the ion wind can be spread over a wider range in addition to the above effects by generating the ion wind from the plurality of receiving wires.

  According to the ion / ozone wind generating apparatus according to the present embodiment, the ion wind generated from the main receiving wire is pushed out to the front in the form of being boosted by the ion wind generated from the sub receiving wire. Even if the electrode pair in the generator is reduced in size, the ion wind generated by the corona discharge is prevented from being scraped as much as possible.

  According to the ion / ozone wind generating apparatus according to the present embodiment, the distance from a certain discharge point on the discharge line to the power reception point on a certain power receiving line and the distance to the certain discharge point is the minimum. And the distance from the certain discharge point to the power receiving point at the power receiving line different from the certain power receiving line and the distance from the certain discharge point to the minimum is substantially the same, An ionic wind having substantially the same air volume is generated from each power receiving point, and an ionic wind covering a wide range can be generated.

  According to the ion / ozone wind generator according to the present embodiment, in addition to the above-described effect, the discharge unit and the power reception unit of the ion / ozone wind generator are segmented, so that the ion / ozone wind generator is In the case of installing in a corner, etc., a suitable shape can be obtained.

  According to the ion / ozone wind generating apparatus according to the present embodiment, in addition to the above-described effects, the discharge unit and the power receiving unit of the ion / ozone wind generating apparatus are curved line segments, and the discharge unit and the power receiving unit are the same. By curving in the direction, the ion / ozone wind generator is suitable for installation in the corner of the room, and the ion / ozone wind can be generated uniformly over a wide range.

  According to the ion / ozone wind generating apparatus according to the present embodiment, in addition to the above-described effect, the discharge / reception part of the ion / ozone wind generating apparatus is formed into an annular shape so that the ion / ozone wind is transmitted around the power receiving part 360. When the ion / ozone wind generator is installed at the center of the ceiling of the room, etc., the ion / ozone wind can be spread throughout the room.

  According to the ion / ozone wind generator according to the present embodiment, in addition to the above-described effect, the discharge part and the power receiver of the discharge part are similar to each other by making the discharge part and the power receiver of the ion / ozone wind generator similar to each other. The distance from the power receiving point can be made close to uniform, and the amount of ion / ozone wind generated from the power receiving unit can be made close to uniform.

<Other changes and usage>
In the ion / ozone wind generating apparatus according to the present embodiment, the shape of the discharge electrode may be a three-dimensional shape (for example, a spherical shape) (in this case, the discharge electrode is cut at a plane where the power receiving portion of the counter electrode exists). In this case, it is only necessary that the shape of the outer periphery of the cross section of the three-dimensional discharge electrode is substantially similar to the power receiving portion of the counter electrode).

  The ion / ozone wind generator according to the present embodiment can be used as a sterilizing / deodorizing device and also as an ionic water / sterilizing water generating device.

  In the apparatus according to this embodiment, ions and / or ozone are generated by corona discharge, and further, an ionic wind with a large air volume is generated. It can be used as an ozone wind generator. In addition, since a large volume of ionic wind is generated, it is possible to generate ions and ozone without using a pump and send them to the space where the object to be sterilized / deodorized is placed. It can also be used as a device.

  The ion / ozone wind generator according to the present embodiment can be used for sterilization and deodorization of seawater and fresh water using an air stone / nano bubble air supply source. In other words, since it is indispensable for the nanobubble generator to take in air, the ion / ozone wind reacts in water by combining the ion wind guide member and the feed path and using it as an air supply source for the nanobubbles. Ionized water / sterilized water can be made easily. As a result, the use of sterilization in the fish tanks for fishery, such as the whitening effect using the bleaching action that is the characteristic of ozone and the removal of oil deep in the pores by the sterilization washing of the skin by the synergistic effect of ozone water and nanobubbles, In addition to deodorization, sterilization of culture broth in hydroponics, etc., and also in kitchens, etc., sterilized water is generated using the discharge pressure of the water supply as a power source, and oil and fat can be easily decomposed by effective sterilization / deodorization and ozone water Inexpensive and safe.

  Further downsizing of the ion / ozone wind generator {for example, downsizing the external dimensions of the ion / ozone wind generator to a length of 7 cm × width of 7 cm × height of about 3 cm, that is, easy to grip with one hand} When the purpose is to save space in the electrode configuration {for example, a counter electrode having a diameter of about 1 cm (preferable range is 5 mm to 5 cm) is arranged as shown in FIG. B1, and the needle electrode and the counter electrode are separated from each other. When the distance is about 1 to 2 cm (preferred range is 1 mm to 2 cm)}, the ion / ozone wind generator can be carried in a pocket or bag of clothes. It is easy to use the ion / ozone wind generator when necessary (for example, when you want to remove the odor source attached to your body or clothes) or as close to the sterilization / deodorization object as possible. Become. In addition, when the ion / ozone wind generator is downsized, it is permanently installed in facility facilities in restaurants, game centers, pachinko halls, etc. (for example, a gap between counters in restaurants and game machine facilities in entertainment facilities). ), And the use of providing a personal air purifying space for each customer by partitioning a bad odor source (for example, sidestream smoke of cigarettes) from a neighbor.

≪Example of changes related to counter electrode≫
In addition, the counter electrode (for example, FIG. B1) shown as a conceptual diagram in the above description is a separate conductive member so that each of the first counter electrode 130a and the second counter electrodes 130b to 130g is planar and annular. This is an image in which the separate conductive members are processed so as to be adjacent to each other (for example, soldered) (hereinafter, this processed image is referred to as a bonding process). On the other hand, the counter electrode (for example, FIGS. C5 to C6) shown as a structural diagram is an image in which an annular through-hole is formed in one flat conductive member (hereinafter, this processing image). Is called drilling). Thus, due to the difference in processing method, the overall structure of the counter electrode can be different as shown in this example. However, as described above with reference to FIG. A1, in consideration of the fundamental mechanism of corona discharge generation, the portion of the counter electrode where the distance between the needle electrode and the counter electrode is closest (that is, the annular counter electrode) In the counter electrode processed by either joining or drilling, the corona discharge is excellent at the inner peripheral edge of the annular counter electrode. It does not change that discharge occurs. And when actually manufacturing the counter electrode, it is easier to form the counter electrode in the perforation process than in the joining process, but this is only supposed to be a flat plate as the counter electrode. That is why (assuming that the counter electrode is cylindrical, if the counter electrode is formed by drilling, the counter electrode itself is likely to be enlarged and the drilling itself is difficult. Can be said). That is, when actually manufacturing the counter electrode, it can be said that it is more advantageous to make the counter electrode flat than to make the counter electrode cylindrical.

  However, when the mechanism of ion wind generation based on corona discharge is taken into account, the generated ion wind is reduced when the counter electrode is formed by drilling rather than when the counter electrode is formed by bonding. Is assumed. Here, the ion wind generation mechanism is generally opposed to the needle electrode by repeatedly colliding with air molecules while ions released from the needle electrode during the corona discharge migrate toward the counter electrode. Although it is said that the air flow is generated toward the electrode, in the present invention, attention is also paid to the negative pressure generated by the air flow and the effect of increasing the ionic wind by the intake air flow of outside air into the space where the negative pressure is generated. doing. For example, as apparent from the location where the ion wind is generated as shown in FIG. A1, when corona discharge occurs at the inner peripheral edge portion of the annular counter electrode, the ion wind is pushed out from the vicinity of the inner peripheral edge portion toward the front surface. At that time, negative pressure is generated on the back side of the annular portion of the counter electrode (the surface on the side not facing the needle electrode). Then, the outside air surrounding the outer periphery of the counter electrode is sucked toward the space where the negative pressure is generated, and the wind force of the ion wind pushed out toward the front by the sucked outside air increases (this In this respect, it can be said that it is more advantageous to make the counter electrode have a flat plate shape than to make the counter electrode have a cylindrical shape).

  Based on such an understanding of the mechanism of ion wind generation, a preferred embodiment in the case of forming the counter electrode by drilling will be described in detail. First, FIG. D1 (left) is a conceptual diagram in the case where the counter electrode shown in FIG. B1 (b) is formed by drilling, and as shown in the figure, one flat conductive member 130 is formed. On the other hand, the entire counter electrode is formed by drilling annular through holes corresponding to the first counter electrode 130a and the second counter electrodes 130b to 130g. Here, in the present example, in view of an error that may occur when the annular through-hole is formed, the first counter electrode 130a and the second counter electrodes 130b to 130g are arranged so as to be separated from each other by at least several mm (1 to 3 mm). Has been. Further, in this example, by forming the flat conductive member 130 in a substantially rectangular shape, for example, holes for supporting the conductive member 130 at four corners of the substantially rectangular shape (as shown in FIG. C5). A hole for assembling a simple device).

  When a needle-like electrode serving as a discharge portion for each counter electrode in the first counter electrode 130a and the second counter electrodes 130b to 130g thus formed is provided and a potential difference is generated between the electrodes, the first counter electrode Corona discharge mainly occurs at the inner peripheral edge portions of 130a and the second counter electrodes 130b to 130g (in this example, a double annular structure is formed, but the inner peripheral edge portion and the outer peripheral edge portion of the inner annular structure are formed. Corona discharge occurs at both inner peripheral edges of the annular structure). When the ion wind is pushed out from the vicinity of the inner peripheral edge portion toward the front surface, a negative pressure is generated on the back side of the annular portion of the counter electrode (the surface on the side not facing the needle electrode). This is the same as the action indicated by B2.) However, the conductive member 130 shields the outside air that surrounds the periphery S of the counter electrode and sucks the outside air that exists between the counter electrode and the needle electrode toward the space where the negative pressure is generated. It is assumed that there will be a situation. Therefore, as shown in FIG. D1 (right), it is preferable to provide a suction hole 130S so that outside air can pass through the conductive member 130 to be sucked. If the distance between the suction hole 130S and the outer periphery of the second counter electrodes 130b to 130g is too far away, the distance between the outside air to be sucked and the space where the negative pressure is generated becomes large. Moreover, there is a possibility that the effect of increasing the wind force of the ionic wind may be reduced due to an increase in the difference between the direction in which the ionic wind is generated and the movement direction of the outside air to be sucked. Therefore, the distance between the suction hole 130S and the outer periphery of the second counter electrodes 130b to 130g is preferably equal to or less than the diameter of the second counter electrodes 130b to 130g (or 1 / n or less of the diameter; n is a natural number). Become.

  From the above, when the counter electrode is formed by perforation, the suction hole 130S is surrounded so as to surround the outside of the second counter electrodes 130b to 130g (the side that is not adjacent to the other counter electrode in a certain second counter electrode). By providing the above, the suction effect of the outside air surrounding the outer periphery of the counter electrode based on the mechanism of the ion wind generation to which the present invention is focused, and the ion wind pushed out from the counter electrode in the front direction by the suction effect The effect of increasing wind power can be expected. Further, not only the effect of increasing the wind force of the ion wind but also the merit that the risk of adversely affecting the human body is reduced because the ion wind containing ozone is diluted by the outside air. That is, providing a counter electrode capable of generating a good (good) ionic wind without separately providing a device for increasing the wind force of ion wind and a device for removing ozone, and Even when the counter electrode is actually manufactured, it is possible to easily form the counter electrode by this modification (particularly, by making the counter electrode into a flat plate shape).

  In addition, in this example, although illustrated only about the point which makes the suction hole 130S the circumferential hole, it is not necessarily limited to this. That is, since the shape of the counter electrode formed by the bonding process is more suitable, various forming methods with the purpose of approaching the shape can be exemplified. For example, in the second counter electrodes 130b to 130g, the suction holes 130S may be provided so as to be curved along an arc that is not adjacent to the other counter electrodes. Further, it may be provided so as to surround the second counter electrodes 130b to 130g, or, for example, a plurality of substantially triangular holes along the arc may be provided. In addition, if there is no need to make the conductive member 130 square, the conductive member 130 itself may be circular (for example, the outer portion of the suction hole 130S in FIG. C11 is removed) or the circular shape. Further, an unnecessary portion may be removed (the second counter electrode 130b to 130g may be removed along an arc not adjacent to the other counter electrode). However, when the shape is as shown in FIG. C11 (right), compared to the shape of the counter electrode formed by the joining process, it is negative on the back side of the annular portion of the counter electrode (the surface not facing the needle electrode). Since the suction path of the outside air to the space where the pressure is generated (especially the outside air surrounding the periphery S of the counter electrode and existing between the counter electrode and the needle electrode) can be narrowed, the suction force of the outside air Can be strengthened (the wind power of the outside air to be sucked in increases). Therefore, when the counter electrode is formed by perforation, it is desirable to design so as to have an optimum shape in consideration of such effects.

  Also, as shown in FIGS. D2 (a) and (b), at first glance, there are a plurality of main electrode pairs, and the sub-electrode pairs are arranged so as to surround them {FIG. A plurality of annular counter electrodes illustrated in bold lines in b) are regarded as an annular counter electrode in the main electrode pair (and an annular counter electrode indicated by a thin line arranged on the outer periphery is an annular counter electrode in the sub electrode pair). Even if it is the structure which can be comprised}, it may be comprised as an aggregate | assembly of what has one set of main electrode pairs, and the sub electrode pair is arrange | positioned so that it may be surrounded. That is, as shown in the "annular counter electrode image diagram in the main electrode pair" in the lower box in the same figure, among the annular counter electrodes indicated by bold lines, the annular counter electrode located in the center is the annular counter electrode in the main electrode pair, It will be supplemented that the annular counter electrode indicated by the thick line around it is regarded as the annular counter electrode in the sub electrode pair, and can be understood as an aggregate. Therefore, even when the suction hole 130S is provided along the outer periphery of the sub electrode pair shown in FIG. D2 (b), the main electrode pair is provided and the sub electrode pair is arranged so as to surround it. It can be said that the suction hole 130 </ b> S is provided along the outer periphery.

  Here, as in the ion / ozone wind generator 100-3 according to FIG. C4, as the configuration in which the distance (discharge distance) between the discharge point of the discharge electrode 120 and the power reception point of the counter electrode 130 is made equal, Various things are possible. For example, as shown in FIG. D3 (a), when viewed in the cross section, there are a plurality of power receiving points of the counter electrode 130 in a circular shape centered on the discharge location (edge portion) of the discharge electrode 120. Can be considered. In this case, a plurality of power receiving points of the counter electrode 130 are separated from each other in the cross section, and an ion wind is ejected from the separated space. In FIG. D3 (a), the counter electrode 130 has a circular cross section, but the cross section is circular (triangular and square) shown in FIGS. D3 (b) and D3 (c). Or the linear shape shown in FIGS. D3 (d) to D3 (f). In this case, the overall shape of the discharge electrode 120 and the counter electrode 130 is a shape rotated around the major axis direction of the discharge electrode 120 shown in the figure, or the minor axis direction of the discharge electrode 120 shown in the figure. A rotated shape or the like can be considered.

<< Fourth Embodiment >>
Here, the ion ozone wind generator according to the second embodiment and the third embodiment described above is
It is possible to generate ion wind in a flat shape (over 360 °) (by making the direction of the generated ion wind multi-directional, for example, it is configured to spread the ion wind over the entire room) However, there is room for improvement in terms of uniformly spreading the ion / ozone wind throughout the space. More specifically, since the ion / ozone wind generator according to the second and third embodiments ejects the ion wind as a plane, the entire space including the space above and below the plane is also included. When considering the spread of the ion, ozone and Ozone were unevenly distributed. In view of this, an ion / ozone wind generator has been invented that can diffuse ions (ion wind) generated more spatially by adopting a configuration different from those of the second and third embodiments described above. . Hereinafter, such an ion / ozone wind generator will be described in detail as a fourth embodiment.

  The basic configuration of an ion / ozone wind generator 100-4 according to this embodiment is as shown in FIG. That is, as described above, the cylindrical guide member 140-4 having the needle-like discharge electrode 120-4 and the annular counter electrode 130-4 and capable of introducing the ion wind generated between these electrodes is provided. The guide member 140-4 has an outlet 141-4 (constriction 141-4) that is an opening through which ion wind is ejected, and a diameter (ring diameter) larger than the constriction 141-4. An intake opening 142-4 that serves as a wind intake port, and a reduced diameter portion 140r-4 that is reduced in diameter from the intake opening 142-4 toward the narrowed portion 141-4. The diameter (ring diameter) of the portion 142-4 is configured to be larger than that of the counter electrode 130-4. The guide member 140-4 may be fixed to the ion / ozone wind generator 100-4 by an appropriate method.

Here, with reference to FIG. E1, the specific configuration of the guide member 140-4 and the counter electrode 130-4 of the ion / ozone wind generator 100-4 according to the present embodiment will be described in detail. The diameter (ring diameter) of the jet outlet 141-4 is R _A , the diameter (ring diameter) of the intake opening 142-4 is R _B , and the distance (guide member 140) between the jet outlet 141-4 and the suction opening 142-4. -4 height with respect to the axial direction) of d, the diameter of the counter electrode 130-4 (the ring diameter) upon the _{R 1,} R a / _{R 1} is greater than 1, preferably 1.1 to 3.5, more preferably 1.2 to 3, particularly preferably 1.3 to 1.8. The upper limit of R _A / R ₁ is not particularly limited, but is less than 4, for example. R _A / R _B is more than 1, preferably 1.1 to 3, and more preferably 1.2 to 3. R _A / d is not particularly limited, but is preferably 0.1 to 2, and more preferably 0.3 to 1.5. By making the configuration of the guide member 140-4 in such a range, the effect of this embodiment can be further enhanced.

  Further, the guide member 140-4 is not limited to a frustum shape (conical frustum shape) as shown in FIGS. 1 and E1, and for example, as shown in FIGS. E2 (a) and E2 (b). The diameter-reduced portion 140r-4 of the guide member 140-4 has a curved cross-sectional diameter from the intake opening 142-4 toward the jet outlet 141-4 {the cross-section here refers to the member axis (the direction in which the ion wind travels) A vertical section of the internal space with respect to the (axis) direction is shown. } May change (the cross-sectional area of the opening gradually decreases while increasing the rate of change).

  Here, the narrowed portion (the narrowed portion 141-4) in the above-described configuration may be any portion in the member (guide member 140-4) where the cross-sectional area of the internal space with respect to the central axis direction is substantially minimum. The narrowed portion 141-4 may not coincide with the ejection port. More specifically, for example, as shown in FIGS. E3 (a) and E3 (b), a constricted portion 141-4 is provided between the intake opening 142-4 and the jet outlet (jet outlet 143-4). And a reduced diameter portion 140r-4 having a reduced cross-sectional diameter (curved to a reduced diameter) from the intake opening 142-4 toward the narrowed portion 141-4. This is a structure provided with an enlarged diameter portion 140S-4 whose sectional diameter increases in a curved line toward the jet nozzle 143-4 (in which the sectional diameter increases). In addition, the shape of the enlarged diameter portion 140S-4 and / or the reduced diameter portion 140r-4 in the case of providing the enlarged diameter portion 140S-4 is not particularly limited, and the sectional diameter increases independently in a curved manner ( The shape may be selected from a shape in which the diameter of the cross section increases, a frustum shape in which the cross section diameter increases linearly, and the like.

  In this case, it is preferable that the enlarged diameter portion 140S-4 has a shape (so-called trumpet shape) whose sectional diameter changes in a curved manner. By adopting such a shape, an air pocket (a portion surrounded by a dotted line in FIG. E3 (a)) in which an ion wind after passing through the constricted portion 141-4 is difficult to occur is generated. That is, since the inner wall of the guide member 140-4 becomes a curved surface whose diameter increases from the narrowed portion 141-4 toward the jet outlet 143-4, the ion wind directed in the vicinity of the narrowed portion 141-4 gradually increases. As a result, the ionic wind is unlikely to exist and air pockets with non-uniform air pressure are generated. As a result, a turbulent flow is generated in the pocket portion, and the ion wind ejected from the ejection port 143-4 is further diffused.

  Similarly, the structure in which the air pocket is formed by the enlarged diameter portion 140S-4 may be a structure in which the enlarged diameter portion 140S-4 is rapidly expanded. For example, a structure in which an annular plane member is provided in which the jet nozzle 141-4 is an inner peripheral edge (a structure in which the enlarged diameter portion 140S-4 extends in a direction substantially perpendicular to the axial direction of the ion wind) is adopted. Even in this case, it is considered that an air pocket is formed in the vicinity of the outer peripheral edge of the ring.

  Here, in the ion / ozone wind generating apparatus 100-4 according to the present embodiment, a member capable of diffusing the ion wind by facing the ion wind so as to inhibit the progress of the ion wind may be provided. . As a more specific configuration, for example, as shown in FIG. E4, a conical splitter 145-4 is provided at the jet outlet 143-4 of the ion / ozone wind generator 100-4 according to FIG. E3 described above. It is. In such a configuration, the ion wind ejected from the jet outlet 143-4 spreads by the splitter 145-4 and is forcibly diffused. Furthermore, since turbulent flow can occur at the back of the splitter 145-4, it can be considered that the ion wind is more diffused. The shape of such a splitter 145-4 is not particularly limited. From the tip (where the ion wind can first contact), the shape is such that the ion wind is diffused efficiently but does not interfere with the ejection of the ion wind. It is preferable that the cross-sectional area gradually increases (the cross-section increases in diameter) from the rear end (where the ion wind can finally contact) (for example, a weight shape as shown in FIG. E4) (Conical)}. The diameter of the maximum diameter portion of the splitter 145-4 (the bottom surface when the splitter 145-4 is conical) is not particularly limited, and may be set as appropriate according to the degree of diffusion of the ion wind. The diameter can be changed as appropriate, such as a diameter of 1/1 to 1/4 with respect to the diameter of 141-4. The splitter 145-4 is arranged in such a manner that all of the splitters 145-4 are inserted into the internal space of the guide member 140-4; some of them are inserted into the internal space of the guide member 140-4. Any of the form existing outside the internal space of the guide member 140-4; the form existing entirely outside the internal space of the guide member 140-4 may be used. Further, the splitter 145-4 may be fixed to the ion / ozone wind generator 100-4 by an appropriate method. In addition to the ion / ozone wind generator 100-4 (that is, the structure in which the enlarged diameter portion 140S-4 is provided) according to FIG. E3 described above, the splitter 145-4 is not shown in FIG. 1 or FIG. The ion / ozone wind generator 100-4 (that is, the structure in which the enlarged diameter portion 140S-4 is not provided) can be similarly installed. An ionic wind diffusion effect can be achieved.

  Here, in this embodiment, in order to enhance the effect of the invention, the counter electrode 130-4 exists in the internal space of the guide member 140-4 (the counter electrode 130-4 is covered with the guide member 140-4). However, the present invention is not limited thereto, and a part or all of the counter electrode 130-4 may be configured to exist outside the internal space of the guide member 140-4 (that is, the counter electrode 130-4 The electrode 130-4 may exist in a region opposite to the narrow portion 141-4 side when viewed in a plane where the intake opening 142-4 exists.

  Further, in order to further increase the diffusion efficiency of the ion wind in the vicinity of the jet outlet of the guide member 140-4, the intake opening 142-4 and the jet outlet 141-4 (constriction 141-4) are substantially similar in shape. However, the present invention is not limited to this, and the intake opening 142-4 and the jet outlet 141-4 may be formed in a similar shape (for example, the intake opening 142-4 is formed in a circular shape). And the jet nozzle 141-4 has a rectangular shape). In this case, the shape of the reduced diameter portion 140r-4 can be appropriately changed in accordance with the shapes of the intake opening 142-4 and the jet outlet 141-4. Similarly, the shape of the intake opening 142-4 is preferably substantially similar to the shape of the annular electrode 130-4, but is not limited to this, and the shape of the annular electrode 130-4 and the intake opening 142- 4 may be formed in a non-similar shape (for example, the annular electrode 130-4 is circular and the intake opening 142-4 is rectangular).

  Furthermore, in this embodiment, the axis of the constricted portion 141-4 (annular axis), the axis of the intake opening 142-4 (annular axis), and the axis of the counter electrode 130-4 are substantially aligned with each other. However, the positions of these axes may be deviated as long as the effects of the invention are not impaired.

  Here, the counter electrode 130-4 according to the present embodiment has a monocyclic structure, but is not limited thereto, and may have a multi-ring structure. For example, as shown in FIGS. E5 and E6, a double ring structure having a main ring electrode 131-4 and a sub ring electrode 132-4 may be used.

Here, when the counter electrode 130-4 has a multiple ring structure, the ring diameter of the jet port of the guide member 140-4 is a ring of the main ring electrode 131-4 which is a counter electrode capable of generating main ion wind. (The main ion wind and the secondary ion wind have different flow rates, and the main ion wind is the main factor. Therefore, the main ion wind is not the entire ion wind generated by the multi-ring electrode, but the main ion wind. Just focusing on the wind can produce the above effects). When the counter electrode 130-4, which is a multiple annular electrode, and the guide member 140-4 according to this embodiment are combined, the counter electrode 130-4 may be configured to be larger than the ring diameter of the plurality of annular electrodes including the main annular electrode. The diameter may be larger than the entire diameter of the multiple annular electrode. For example, the ring diameter _{R 1} of the primary annular electrode 131-4, the ring diameter _{R 2} of the secondary annular electrodes 132-4, with respect to the ring diameter _{R B} ring diameter _{R A} and the intake opening 142-4 jets 141-4, The ion / ozone wind generator 100-4 shown in FIG. E5 assumes the relationship of R _B > R _A > R ₂ > R ₁ , and the ion / ozone wind generator 100-4 shown in FIG. _A relationship of _B > R ₂ > R _A > R ₁ is assumed. Similarly, for example, when various members other than the sub annular electrode (for example, a member made of a resin material for holding the annular electrode) are provided around the main annular electrode 131-4, the main annular electrode 131-4 is also provided. The diameter of the electrode 131-4 and the diameter of the jet outlet of the guide member 140-4 should satisfy the above relationship.

  Further, the ion / ozone wind generating apparatus 100-4 according to this embodiment includes a configuration having a plurality of electrode pairs (a counter electrode 130a-4 including 132a-4 and 131a-4, and a discharge electrode 120a-4). It is good also as a structure which has multiple electrode pairs. For example, when a plurality of electrode pairs are configured as shown in FIG. B1, the guide member 140-4 is arranged as follows: (1) As shown in FIG. A method of arranging the guide member 140-4 as one counter electrode; (2) a method of arranging the guide member 140-4 on each of the counter electrodes as shown in FIG. E7 (b); It is not limited. The form (2) is that the ion wind ejected from the outlet of a certain guide member is mixed with the ion wind from the adjacent guide member, so that the ion wind in the entire apparatus is more easily diffused. Is preferred. When the ion / ozone wind generator 100-4 has a plurality of electrode pairs, the guide member 140-4 may be arranged only for an arbitrary electrode pair (counter electrode), or other implementations. The configuration described in the embodiments can be applied as appropriate.

  As described above, according to the ion / ozone wind generator according to the present embodiment, the guide member itself is configured to diffuse the ion / ozone wind. It is possible to suppress the attenuation of ion wind inside the guide member. As a result, it is possible to reduce the amount of ozone in direct contact with the object in the vicinity of the jet outlet while diffusing ions in the target space (as a result, it is also used in the vicinity of objects where the bleaching effect by ozone is not desirable). Can do).

<Modification Example of Fourth Embodiment>
The ion / ozone wind generating apparatus according to the fourth embodiment described above has a structure in which the diameter is reduced to the constriction along the traveling direction of the ion wind, and the guide member has a diameter larger than that of the counter electrode. By providing the above, diffusion of ion wind and reduction of ozone concentration in the vicinity of the jet outlet are performed. Next, the concept described above is the concept of the ion / ozone wind generator according to the second embodiment and the third embodiment (that is, the configuration in which the counter electrode is arranged on a plane parallel to the plane on which the discharge electrode exists). ) Will be described in detail as a modified example according to the fourth embodiment.

  As shown in FIG. E8, the ion / ozone wind generating apparatus 100-4 ′ according to the present embodiment includes, as an electrode pair, an annular discharge electrode 120-4 ′ and a plane where the discharge electrode 120-4 ′ exists (plane X ) And the other side of the plane X, the annular counter electrode 130a-4 ′ existing on one plane side of the plane X and substantially parallel to the plane X (referred to as plane A1). And an annular counter electrode 130b-4 'existing on a plane substantially parallel to the plane X (referred to as plane B), and further, the guide member so as to cover the electrode pair 140-4 'is provided.

More specifically, as shown in FIG. E8, the guide member 140-4 ′ includes a truncated conical upper member 140a-4 ′, a truncated conical lower member 140b-4 ′, and an upper member 140a. -4 ′ and the bottom surface side of the lower member 140b-4 ′, and a spout 141- formed as a gap between the upper member 140a-4 ′ and the lower member 140b-4 ′. 4 ', an air hole 144a-4' that is an air inlet provided on the head side of the upper member 140a-4 ', and an air hole that is an air inlet provided on the head side of the lower member 140b-4' 144b-4 ′ and the guide member 140-4 ′ from the central axis direction (air hole 144a-4 ′ and air hole 144b-4 ′ direction) toward the jet outlet 141-4 ′. Reduced diameter portion 140r-4 ′ configured to reduce the height (diameter) and reduced diameter portion 140r-4 ′ Having a 'different ends side (air holes 144a-4 and''intake opening 142-4 is a virtual regions provided on the veranda of and air holes 144b-4)' jetting port 141-4. Further, in the present embodiment, ejection ports 141-4 'height (diameter) _{R A} and intake openings 142-4' height (diameter) _{R B} and the counter electrode 130a-4 'and the counter electrode 130b The distance R ₁ to −4 ′ is R _B > R _A > R ₁ .

  In other words, the ion / ozone wind generating apparatus 100-4 ′ according to the present embodiment is a constituent part of the cross section of the ion / ozone wind generating apparatus 100-4 shown in FIG. 1 and FIG. -4 power receiving points (a power receiving point 130x-4 corresponding to the upper end of the counter electrode 130-4 and a power receiving point 130y-4 corresponding to the lower end of the counter electrode 130-4 in FIG. 2A), With respect to the discharge point of the discharge electrode 120-4 (the discharge point 120x-4 corresponding to the right end of the discharge electrode 120-4 in FIG. 2A) and the reduced diameter portion 140r-4}, the positional relationship is maintained. It is also possible to consider the formed rotating body (in this case, the discharge point 120x-4, the power reception point 130x-4, the power reception point 130y-4, and the reduced diameter portion 140r-4 in FIG. 2 are the discharge points in FIG. E8. 120x-4 ', receiving point 130x-4 , The receiving point 130y-4 'and reduced diameter portion 140r-4', corresponding respectively).

  Similar to the ion / ozone wind generator 100-4 according to the fourth embodiment, the ion / ozone wind generator 100-4 ′ according to the present embodiment and the guide member 140 are ejected from the jet outlet 141-4 ′. Since a gap is generated between -4 ′ and the ionic wind, the gap is diffused by the gap. That is, according to the ion / ozone wind generator 100-4 ′, while generating the ion wind over 360 ° with respect to the installation surface, the ozone concentration in the vicinity of the jet outlet is reduced, and the ion wind is made more space-saving. Diffusion (further diffusion in the vertical direction of the plane on which the counter electrode is present).

  The ion / ozone wind generator 100-4 ′ according to this embodiment is the same as the ion / ozone wind generator 100-4 (device provided with the splitter 145-4) according to the fourth embodiment shown in FIG. E4. In addition, a member for further diffusing ion wind ejected from the ejection port 141-4 ′ may be further provided. Although it does not specifically limit as such a member, For example, it is a member which obstruct | occludes a part of the path | route of the ion wind over 360 degree opening part of jet nozzle 141-4 ', More specifically, the Annular shape (doughnut shape) whose cross section is similar to that of the splitter 145-4 shown in FIG. E4 {from the inner peripheral edge (where the ion wind can first contact) to the outer peripheral edge (where the ion wind can finally contact) , Etc., and the like.

  This embodiment is the same as the second embodiment and the third embodiment in that an ion wind is generated along a plane on which an annular (or linear) discharge electrode is placed. It is. Therefore, it is possible to appropriately apply the concepts detailed in the second embodiment and the third embodiment as long as the effects of the invention are not impaired.

«Fifth embodiment»
Here, the ion / ozone wind generating apparatus according to the fourth embodiment reduces the ozone concentration in the vicinity of the jet port by changing the configuration of the jet port, which is a location where the ion / ozone wind jets as a guide member, It was a configuration that allowed ion wind to reach a wide area. Next, unlike the ion / ozone wind generating apparatus according to the fourth embodiment, the ion / ozone wind generating apparatus 100 according to the fifth embodiment mainly intended to reduce the concentration of ozone generated during corona discharge. -5 will be described in detail.

  The basic configuration of the ion / ozone wind generator according to the present embodiment is as shown in FIG. That is, as described above, the ion / ozone wind generator 100-5 according to this embodiment includes a cylindrical (frustum-shaped) counter electrode 130-5 having an internal space, and a part of the counter electrode 130-5. A needle-like discharge electrode 120-5 in which the (tip) is inserted, and the counter electrode 130-5 is an outlet 130α-5 (a narrowed portion 130α-5) that is an opening through which ion wind is ejected. ) And an intake opening 130β-5 serving as a wind inlet having a larger diameter (ring diameter) than the jet outlet 130α-5, and the diameter of the air outlet is reduced from the jet outlet 130α-5 toward the intake opening 130β-5. A reduced diameter portion 130r-5.

Here, with reference to FIG. F1, a more specific configuration of the counter electrode 130-5 of the ion / ozone wind generator 100-5 according to the present embodiment will be described in detail. The diameter (ring diameter) of the ejection port 130α-5. R _α , the diameter (ring diameter) of the intake opening 130β-5 is R _β , and the distance between the jet outlet 130α-5 and the intake opening 130β-5 (the height of the counter electrode 130-5 in the axial direction) is When z is set, R _β / R _α is more than 1, more than 1, preferably 1.1 to 3, more preferably 1.2 to 3. Further, R _α / z is not particularly limited, but is preferably 0.1 to 2, and more preferably 0.3 to 1.5. By making the configuration of the counter electrode 130-5 in such a range, the effect of this embodiment can be further enhanced.

  In the ion / ozone wind generator 100-5 according to the present embodiment, the positional relationship between the discharge electrode 120-5 and the counter electrode 130-5 is not particularly limited, and the discharge is performed outside the internal space of the counter electrode 130-5. The electrode 120-5 may be provided (that is, the discharge electrode 120-5 is opposite to the region where the intake opening 130β-5 exists when viewed from the plane where the intake opening 130β-5 exists). May be provided in the area). Note that, as in this embodiment, the tip of the discharge electrode 120-5 is inserted into the internal space of the counter electrode 130-5, so that the local area of the counter electrode 130-5 and the intake opening 130β-5 is local. Therefore, it is possible to suppress discharge (by making the entire inner wall surface of the counter electrode 130-5 function as a discharge part), and to generate ions / ozone wind with a more uniform and low ozone concentration. On the other hand, when the discharge electrode 120-5 is arranged outside the internal space of the counter electrode 130-5, discharge from the edge portion (for example, the intake opening 130β-5) of the counter electrode 130-5 is performed. In some cases, the ratio becomes high and it is difficult for electric discharge with the inner wall surface of the counter electrode 130-5 to occur (that is, local electric discharge with the intake opening 130β-5 is likely to occur). Therefore, from the viewpoint of further reducing the ozone generation rate, it is preferable to dispose at least a part (tip) of the discharge electrode 120-5 so as to be inserted into the internal space of the counter electrode 130-5.

  Furthermore, in the ion / ozone wind generator according to the present embodiment, it is preferable that the discharge electrode 120-5 does not penetrate to the ejection port 130α-5 side. When discharge electrode 120-5 penetrates to ejection port 130α-5 (when the tip of discharge electrode 120-5 is in a region opposite to intake opening 130β-5 when viewed from the plane where ejection port 130α-5 exists) ) Since the ion wind in the reverse direction from the jet outlet 130α-5 toward the intake opening 130β-5 may be generated, the momentum of the ion wind may be cut off. From this point of view, the distance from the tip of the discharge electrode 120-5 to the jet outlet 130α-5 is z (jet) under the condition that the tip of the discharge electrode 120-5 does not penetrate to the jet outlet 130α-5. 4/5 or less, more preferably 3/4 or less, and 2/3 or less based on the distance between the outlet 130α-5 and the intake opening 130β-5). It is particularly preferred. Further, in this embodiment, the main traction force of the ion wind generated from the jet outlet is the discharge electrode 120-5 and the jet that are directed from the intake opening 130β-5 side to the jet outlet 130α-5 side. Ion wind generated between the vicinity of the outlet 130α-5. Therefore, in order to increase the wind force of the ion wind toward the jet outlet 130α-5, the tip of the discharge electrode 120-5 does not penetrate to the jet outlet 130α-5 side, and the jet outlet 130α is discharged from the tip of the discharge electrode 120-5. The distance to −5 is preferably 1/5 or more, more preferably ¼ or more, based on z (distance between the jet outlet 130α-5 and the intake opening 130β-5). It is suitable and it is especially suitable that it is 1/3 or more.

  Further, the counter electrode 130-5 is not limited to the frustum shape (conical frustum shape) shown in FIGS. 3 and F1, and the reduced diameter portion 130r-5 of the counter electrode 130-5 is an intake opening portion 130β-5. It is good also as a shape from which a cross-sectional diameter changes in a curve toward the jet nozzle 130α-5. At this time, as the shape of the counter electrode 130-5, (1) a convex shape on the outer side of the counter electrode 130-5 as shown in FIG. F2 (a) {similar to a part of a sphere (sphere crown) (Shape)}; (2) As shown in FIG. F2 (b), it may be any shape of a convex shape (so-called trumpet shape) on the inner side of the counter electrode 130-5. When the counter electrode 130-5 has a frustum shape or a trumpet shape, a slight unevenness can be generated in the discharge portion (the relationship between the discharge electrode 120-5 and the counter electrode 130-5) to such an extent that the ozone concentration does not increase. As a result, a discharge relationship close to that when the counter electrode is a multiple ring is formed inside the counter electrode, and further, the ion wind generated inside the counter electrode is smoothly guided toward the jet outlet 130α-5. It is preferable that the momentum of the ion wind is strengthened. From the viewpoint of forming a multiple ring inside the counter electrode due to the structure of the counter electrode, a structure such as providing a groove or a projection that is substantially concentric with the electrode inside the counter electrode is also conceivable.

  Moreover, as shown in FIG. F3, the ion / ozone wind generating apparatus 100-5 according to the present embodiment has a configuration having a plurality of electrode pairs (an electrode pair including a counter electrode 130a-5 and a discharge electrode 120a-5). It is good also as a structure which has multiple. In addition, although this figure is an example at the time of applying the structure of an electrode arrangement | positioning as shown in FIG. B1 as counter electrode 130a-5, the structure which has ion / ozone wind generator 100-5 with several electrode pairs In such a case, the configurations described in the other embodiments can be applied as appropriate.

  Further, the counter electrode 130-5 according to the present embodiment may have a jet ring 130α-5 having a multi-ring structure (the nozzle 130α-5 is regarded as a sub-annular electrode, and is formed into a ring that forms a main ring electrode therein. An electrode may be further provided). With such a configuration, the ion wind generated by the discharge of the main annular electrode and the discharge electrode provided at the jet outlet 130α-5 converts the ion wind generated inside the counter electrode 130-5 into the jet outlet 130α-. It is considered that the momentum of the ion wind that is pulled in five directions and ejected from the ejection port 130α-5 increases.

  In addition, the discharge electrode 120-5 which concerns on this form is not limited to a needle-like electrode, You may use a cyclic | annular discharge electrode.

  As described above, according to the ion / ozone wind generator according to the present embodiment, the generated ozone concentration is lowered, and ions (ion wind) generated inside the counter electrode are guided to the jet outlet. Therefore, it is possible to reduce the amount of ozone in direct contact with the object in the vicinity of the ejection port while ejecting torque ion wind and sufficiently diffusing ions in the target space (as a result, the bleaching effect by ozone It can also be used near objects that are not desirable).

<Modification Example of Fifth Embodiment>
The ion / ozone wind generating apparatus 100-5 according to the fifth embodiment described above includes the counter electrode 130-5 having a structure that reduces the diameter along the traveling direction of the ion wind, so that the ion wind with torque can be generated. Generation and reduction of ozone concentration.

  Next, the concept described above is the concept of the ion / ozone wind generator according to the second embodiment and the third embodiment (that is, the configuration in which the counter electrode is arranged on a plane parallel to the plane on which the discharge electrode exists). ) Will be described in detail as a modified example according to the fifth embodiment.

  As shown in FIG. F4, an ion / ozone wind generator 100-5 ′ according to this embodiment includes an annular discharge electrode 120-5 ′ and a counter electrode 130-5 ′ that covers the discharge electrode 120-5 ′. Is provided.

More specifically, as shown in FIG. F4, the counter electrode 130-5 ′ includes a truncated conical upper member 130a-5 ′, a truncated conical lower member 130b-5 ′, and an upper member 130a. −130′− formed as a gap between the bridge 130c-5 ′ connecting the bottom surface side of −5 ′ and the bottom surface side of the lower member 130b-5 ′ and the upper member 130a-5 ′ and the lower member 130b-5 ′ 5 ', an air hole 134a-5' that is an air inlet provided on the head side of the upper member 130a-5 ', and an air hole that is an air inlet provided on the head side of the lower member 130b-5' 134b-5 ′ and the counter electrode 130-5 ′ from the central axis direction (air hole 134a-5 ′ and air hole 134b-5 ′ direction) of the counter electrode 130-5 ′ toward the jet outlet 130α-5 ′. The reduced diameter portion 130r-5 ′ configured to have a large height (diameter) and the injection of the reduced diameter portion 130r-5 ′ Having a 'different ends side (air holes 134a-5 and''intake opening 130β-5, which is a virtual regions provided on the veranda of and the air hole 134b-5)' mouth 130α-5. Further, in this embodiment, the spout 130α-5 'in height (diameter) R _alpha and the intake opening 130β-5' in height (diameter) R _beta have a R β> R _α.

  In other words, the ion / ozone wind generator 100-5 ′ according to this embodiment is a cross section of the ion / ozone wind generator shown in FIG. 3 {two discharge lines of the counter electrode 130-5 (in FIG. 3). The discharge line corresponding to the upper cross section of the counter electrode 130-5 and the discharge line corresponding to the lower cross section of the counter electrode 130-5) and the power receiving point of the discharge electrode 120-5 (in FIG. 1, the discharge electrode 120- The power receiving point corresponding to the tip of the needle 5)} can be regarded as a rotating body formed while maintaining its positional relationship.

  Also in this embodiment, since the discharge is performed on the entire inner wall surface of the counter electrode 130-5 ′, the local discharge can be reduced and the ozone concentration can be reduced. Since the diameter-reduced portion 130r-5 ′ whose sectional area gradually decreases toward −5 ′, the ions generated near the intake opening 130β-5 ′ are included inside the counter electrode 130-5 ′. Uniformly generated ions are surely guided to the vicinity of the jet outlet 130α-5 ′, and an ion wind having a torque in which the ion concentration contained in the ion wind is increased can be obtained. That is, according to the ion / ozone wind generator 100-5 ′, it is possible to suppress the ozone concentration in the vicinity of the jet outlet while generating an ion wind having a torque over 360 ° with respect to the installation surface. It becomes.

  In addition, this form is the same as that of 2nd Embodiment and 3rd Embodiment by the point that an ion wind is generated along the said plane, when the plane where an annular discharge electrode exists is assumed. Therefore, the concept detailed in the second embodiment and the third embodiment can be applied as appropriate without departing from the effects of the invention.

  Here, the ion / ozone wind generator 100-4 according to the fourth embodiment and the ion / ozone wind generator 100-5 according to the fifth embodiment particularly reduce the ozone concentration in the vicinity of the jet nozzle. Have the same problem. Therefore, an ion / ozone wind generator with further improved effects of the invention can be obtained by appropriately combining these. For example, the splitter 145-4 described in the ion / ozone wind generator 100-4 according to the fourth embodiment may be provided to the ion / ozone wind generator 100-5 according to the fifth embodiment. With reference to the shape of the guide member 140-4 of the ion / ozone wind generator 100-4 according to the fourth embodiment, the counter electrode 130-5 of the ion / ozone wind generator 100-5 according to the fifth embodiment The shape may be changed as appropriate.

  Next, the present invention will be described more specifically with reference examples and reference comparative examples, but the present invention is not limited to these examples.

<< Reference Example I >>

For Reference Example I, an ion wind is generated using an ion wind generator having an electrode pair having the shape shown in FIG. C5, and the points A to H are equally spaced on the outer periphery of the counter electrode 330 (power receiving unit 331). The wind speed of the ion wind was measured at 8 locations up to. Further, the potential difference (applied voltage) between the discharge electrode and the counter electrode when generating the ion wind is 7000 [V] (current: 500 μA), and the measurement environment is a temperature of 25 degrees Celsius and a humidity of 60%.

For Reference Example 1, Reference Example 2, Reference Comparative Example 1, Reference Comparative Example 2, and Reference Comparative Example 3, an ion wind is generated using an ion wind generator equipped with the counter electrode shown in FIGS. The wind speed of the ion wind was measured by the method shown in FIG. The electrode size of each device is as shown in Table T4 below. Further, the potential difference (applied voltage) between the needle electrode and the counter electrode when generating the ion wind was set to 7000 [V] (current: 500 μA), and the height of the stage on which the anemometer was placed was set to 39 mm.

(Reference Example 1)
As shown in FIG. T1, the structure of Reference Example 1 has a main electrode pair and a plurality of sub electrode pairs positioned so as to surround the main electrode pair. It is what.

(Reference Example 2)
As shown in FIG. T2, the structure of Reference Example 2 has the same structure as Example 1 except that each counter electrode has a main annular counter electrode and a sub-annular counter electrode. .

(Reference Comparative Example 1)
As shown in FIG. T3, the structure of Reference Comparative Example 1 is provided with a plurality of adjacent electrode pairs so as to surround one set of electrode pairs. The counter electrode is cylindrical.

(Reference Comparative Example 2)
As shown in FIG. T4, the structure of the second reference comparative example is provided with a plurality of electrode pairs arranged in series. The counter electrode is cylindrical.

(Reference Comparative Example 3)
As shown in FIG. T5, the structure of the reference comparative example 3 is provided with a plurality of electrode pairs arranged in series. Each electrode pair is planar and annular.

(Measurement results of Reference Example and Reference Comparative Example)
The measurement results of the above reference examples and reference comparative examples are shown in Table T5 below. As shown in Table T5, the wind speed of the ion wind generated by the ion wind generator of Reference Example 1 is significantly greater than the wind speed of the ion wind generated by the ion wind generators of Reference Comparative Examples 1 to 3. I understand that.

  In addition, as will be described in detail below, from the results of this measurement, as in the present invention, (A) a main electrode pair and a plurality of sub electrode pairs positioned so as to surround the main electrode pair, (B) Only when each electrode pair is planar and annular, the effect of significantly amplifying wind power can be obtained. (A), (B) It can be said that the amplification effect is small.

  Specifically, comparing Reference Comparative Example 1 and Reference Comparative Example 2, when the counter electrode is cylindrical, a plurality of electrode pairs are arranged so as to surround the main electrode pair from the series arrangement. Even if it changes to the arrangement | positioning which has a pair of subelectrode pair, it turns out that a wind speed becomes only 0.1 m / s, and the amplification effect of a wind force is small. On the other hand, when Reference Example 1 is compared with Reference Comparative Example 3, when each electrode pair is planar and annular, the arrangement of the plurality of electrode pairs is positioned so as to surround the main electrode pair from the series type. When the arrangement is changed to an arrangement having a plurality of pairs of sub-electrodes, the wind speed is significantly increased to 0.3 m / s, and it can be seen that the effect of amplifying the wind force is great.

  Further, comparing Reference Comparative Example 2 and Reference Comparative Example 3, when the arrangement of the plurality of electrode pairs is a series arrangement, even if the shape of the counter electrode is changed from a cylindrical shape to a planar shape and an annular shape, It can be seen that the wind speed is only 0.1 m / s, and the amplification effect of the wind is small. On the other hand, when Example 1 is compared with Comparative Example 1, when the arrangement of the plurality of electrode pairs has a plurality of sub electrode pairs positioned so as to surround the main electrode pair, the shape of the counter electrode is cylindrical. When the shape is changed from a flat shape to an annular shape, the wind speed is significantly increased to 0.3 m / s, and it can be seen that the amplification effect of the wind force is great.

  As described above, it can be seen that the ion / ozone wind generating apparatus according to Reference Example 1 of the present invention generates significantly larger wind power than the apparatus according to Reference Comparative Examples 1 to 3. Further, it can be seen that the effect of amplifying the ion wind by providing a plurality of sub electrode pairs positioned so as to surround the main electrode pair becomes remarkable when each electrode pair is planar and annular.

  Further, it can be seen from the comparison between the reference example 1 and the reference example 2 that each counter electrode has a main annular counter electrode and a sub-annular counter electrode, thereby further exerting a remarkable wind power amplification effect.
