  As described in the above "Background Art", the conventional technique uses a dust collection airflow combined with ions, or filters and cleans the dust collection airflow with a filter, and obtains an airflow necessary for the dust collection. For this reason, the required power is large, and the wind noise and wind noise of the windmill cause noise, which inevitably restricts the installation location.

  In addition, a plurality of attracting winds called electronic air showers are combined and surrounded to create a clean shielding space and to obtain a local cleaning system. The forward component was attenuated, and the distance reached was limited, and the size was limited to obtain the necessary clean shielding space.

  In order to reinforce the flow of the electronic air shower, there is also a technique in which both the discharge electrode and the discharge electrode are elongated so as to make it planar instead of linear, but the flow of the planar electronic air shower is still attracting. It was diffused by the air flow and the advancing component of the air flow was greatly attenuated, and the reach was still a small one that could not exceed the range of several meters.

  Therefore, the first term of the present invention is that a dielectric pole made of a conductive material including a dielectric space, a discharge electrode made of a conductive material arranged on an extension of the center line of the dielectric space, and a charge having a polarity opposite to these two poles. The electron generator is configured to continuously emit an electron shower from the dielectric pole to the dielectric space, and has a certain length in a direction substantially perpendicular to the direction in which the dielectric space and the discharge electrode face each other. A dielectric electrode having a thickness and a discharge electrode are provided, and a planar electron shower penetrating toward the center of the dielectric space having the length is continuously generated, and a dielectric electrode is formed near the end of the dielectric electrode. A forward end component of the electron shower is enhanced by providing a thin linear terminal dielectric pole parallel to the longitudinal direction.

  Further, in the second aspect of the present invention, a dielectric pole made of a conductive material containing a dielectric space, a discharge electrode made of a conductive material arranged on the extension of the center line of the dielectric space, and a charge having a polarity opposite to these two poles The electron generator is configured to continuously emit an electron shower from the dielectric pole to the dielectric space, and has a certain length in a direction substantially perpendicular to the direction in which the dielectric space and the discharge electrode face each other.

By making them close to each other in parallel, the forward component of the electronic shower is further strengthened.

  Further, in the third aspect of the present invention, a dielectric pole made of a conductive material containing a dielectric space, a discharge electrode made of a conductive material arranged on an extension of the center line of the dielectric space, and a charge having a polarity opposite to these two poles The electron generator is configured to continuously emit an electron shower from the dielectric pole to the dielectric space, and has a certain length in a direction substantially perpendicular to the direction in which the dielectric space and the discharge electrode face each other. A dielectric space and a discharge electrode are provided, and a planar electron shower penetrating toward the central direction of the dielectric space having the length is continuously generated. The forward components of the electron shower are further strengthened by being configured so that the extension of the center lines emitted by these electron showers intersect with each other in parallel.

  Further, in the fourth aspect of the present invention, a dielectric pole made of a conductive material containing a dielectric space, a discharge electrode made of a conductive material arranged on an extension of the center line of the dielectric space, and a charge having a polarity opposite to these two poles. The electron generator is configured to continuously emit an electron shower from the dielectric pole to the dielectric space, and has a certain length in a direction substantially perpendicular to the direction in which the dielectric space and the discharge electrode face each other. A dielectric space and a discharge electrode are provided, and a film-shaped electron shower penetrating toward the central direction of the dielectric space having the length is continuously generated, and the discharge ports of these electron showers are longitudinally connected to each other. And at least one or a plurality of sets of electron emission generators for electron emission can be arbitrarily deflected so that the extension of the center line emitted by these electron showers intersects each other. It, the more stable the forward component of the electron shower, corresponding to the right man in the right place, is intended to strengthen.

  The prior art related to the present invention is as described in the above "Background Art". A typical known model relating to the generation of the scattering of electrons and the induction thereof will be described with reference to FIG. Here, a needle-like or projecting discharge electrode 1 and a dielectric pole 3 having a length spaced from the same center line 2 are arranged, and the inside of the dielectric pole 3 is defined as a dielectric space A. When high-voltage electricity having opposite polarities is charged to each other, electrons are emitted from the discharge electrode 1 toward the dielectric space A inside the dielectric electrode 3 up to a voltage before the plasma discharge. Some of them reach the dielectric pole 3, but many electrons still pass through the dielectric space A and pass through the dielectric space A, and are also emitted vigorously from the end of the dielectric pole 3. The flow of the discharged electronic shower D attracts and merges the air in the surrounding air, other odor / bad odor gas molecules, airborne foreign particles and airborne bacteria (hereinafter simply referred to as air). Repeatedly, the forward performance gradually attenuates.

  Considering this electron flow component as an invisible shield, several conventional techniques have been introduced. A typical known example will be described with reference to FIG. 7. The discharge electrode 6 and the dielectric pole 4 having the needle-like protrusions 10 have a length in the direction C perpendicular to the center line 5, and therefore the discharge electrode 6 and the dielectric pole 4. Has a length in the direction C, and the flow of electrons becomes a planar electron shower D having a certain width. However, the attenuation of the flow component of the attracted electrons due to air is large, and the practically usable range is within the industrially usable range, that is, for example, the measured wind speed value converted into the air flow is as low as 0.3 m / s. . The reach from the apparatus of the embodiment described later is about 2.0 to 2.5 m.

  In the present invention, the progress performance of the electron shower can be made stronger continuously. A dielectric pole made of a conductive material containing a dielectric space and a thin linear end dielectric pole at the end of the dielectric pole. And a discharge electrode made of a conductive material disposed on an extension of the center line of the dielectric space, and charges of opposite polarities are added to both the electrodes, and electrons are emitted from the discharge electrodes. An electron flow that is attracted in the direction and vigorously penetrates the center of the dielectric pole proceeds. The flow of electrons penetrating and ejecting from the dielectric pole still proceeds while attracting surrounding air molecules, and it can be confirmed that the progress performance of the flow of planar electrons is remarkably improved as compared with the prior art.

  As shown in FIGS. 1 and 2, the first term of the present invention is that the dielectric electrodes 4a and 4b (hereinafter, the same constituent names are omitted and only the reference numerals are described) and the discharge electrodes arranged on the extensions of the center lines 5a and 5b. 6a and 6b are provided in the longitudinal directions Ca and Cb perpendicular to the direction in which the dielectric spaces Ba and Bb and the discharge electrodes 6a and 6b are opposed to each other, and have a certain length 7a and 7b in parallel with a gap G. In addition, planar electron showers Da and Db penetrating toward the centers of the dielectric spaces Ba and Bb are arranged close to each other in parallel so as to be generated continuously and strongly.

  Further, thin linear end dielectric poles 11a and 11b are provided at the ends of the dielectric poles 4a and 4b in parallel with the longitudinal directions Ca and Cb of the dielectric poles 4a and 4b to enhance the attracting performance of the electronic showers Da and Db. Yes.

  Further, the second term of the present invention is that the dielectric electrodes 4a and 4b and the discharge electrodes 6a and 6b arranged on the extensions of the center lines 5a and 5b are connected to the dielectric spaces Ba and Bb and the discharge electrodes 6a as shown in FIG. Each of the dielectric spaces Ba and Bb provided is configured such that the lengths 7a and 7b of a constant length 7a and 7b intersect each other on the extension lines of the center lines 5a and 5b in directions Ca and Cb orthogonal to the direction in which 6b faces each other. A sheet-shaped electron shower Dc that crosses and merges at the point E on the extended line radiating from the planar electron shower Da and Db that penetrates toward the center is continuously generated. The planar electron shower Dc merged by this cross-merging has greatly improved the forward performance. For example, the distance from the apparatus has been improved to 3.0 to 3.8 m in the same manner as described above.

  Further, the third term of the present invention is that, as shown in FIGS. 4 and 5, the dielectric electrodes 4a and 4b and the discharge electrodes 6a and 6b arranged on the extensions of the center lines 5a and 5b are released from the dielectric spaces Ba and Bb. The electrodes 6a and 6b are provided with constant lengths 7a and 7b in directions Ca and Cb perpendicular to the direction in which the electrodes 6a and 6b are opposed to each other on the extension lines of the center lines 5a and 5b. Of the electron showers Da and Db so that the sheet-shaped electron showers Da and Db penetrating toward the center of Bb and Bb cross and merge to generate a single electron shower Dc continuously. At the end in the length direction that does not hinder the flow, it is a known mechanism that can be arbitrarily set with a deflection mechanism Ra, Rb each composed of, for example, a common hinge pin 8 and fixing screws 9a and 9b. It may be configured.

  In the present invention, unlike the so-called prior art electronic air shower, the air flow is not actively used, that is, a fan for sending air is not used as a necessary condition. In other words, there is no wind noise, no noise at all, no noise for driving the fan, no large driving power is required, and it can be operated with only the voltage power applied to each discharge electrode and dielectric pole, so the required power is It is very small and most importantly it is quiet and very economical.

  In the present invention, as shown in FIGS. 1 and 2, the dielectric electrodes 4a and 4b, the discharge electrodes 6a and 6b arranged on the extensions of the center lines 5a and 5b, the dielectric spaces Ba and Bb, and the discharge electrodes 6a and 6b. Planar electron showers Da having constant lengths 7a and 7b close to each other in parallel directions Ca and Cb perpendicular to opposite directions and penetrating toward the centers of the dielectric spaces Ba and Bb, respectively. And Db are close to each other in parallel and can be generated continuously, the emission force is enhanced by the synergistic effect of the electron showers Da and Db that are continuously generated in parallel and close to each other. Although the practical reach of the electron shower is 2 to 2.5 m, the emission force is enhanced by the synergistic effect of the electron shower generated continuously in parallel in the present invention. Release force and 3.8m to practical reach no 3 was enhanced by single electron shower.

  Further, as shown in FIG. 3, dielectric electrodes 4a and 4b, discharge electrodes 6a and 6b arranged on the extension of center lines 5a and 5b, and dielectric spaces Ba and Bb and discharge electrodes 6a and 6b are opposed to each other. Can be set to intersect with each other in the directions Ca and Cb perpendicular to each other on the extension lines of the center lines 5a and 5b, and the position of the intersection can be arbitrarily set, thereby changing the various circumstances of the surrounding space. It is very easy to obtain an increased discharge range.

  The emission force is enhanced by continuously generating a single electron shower Dc in which the planar electron showers Da and Db penetrating toward the centers of the dielectric spaces Ba and Bb intersect and merge, For example, the practical reach of one electronic air shower of the prior art is 2 to 2.5 m, but the emission force is enhanced by the synergistic effect of the electronic shower that is generated in parallel and continuously according to the present invention. For example, a practical reachable distance of 3 to 3.8 m was enhanced by two electronic curtains in close parallel to each other, and the emission force was enhanced.

  1 and 2, the dielectric electrodes 4a and 4b and the discharge electrodes 6a and 6b arranged on the extensions of the center lines 5a and 5b are connected to the dielectric space Ba. , Bb and discharge electrodes 6a and 6b are provided with fixed lengths 7a and 7b in directions Ca and Cb orthogonal to the direction in which the discharge electrodes 6a and 6b are opposed to each other, and the center lines 5a and 5b are parallel to each other with a fixed gap G. The sheet-shaped electron showers Da and Db penetrating toward the respective centers of the dielectric spaces Ba and Bb are generated, and for example, a positive voltage is applied to the dielectric electrodes 4a and 4b, and a negative voltage is applied to the discharge electrodes 6a and 6b. Are charged using a continuous known charging device.

  At the end of the dielectric poles 4a and 4b opposite to the discharge electrodes 6a and 6b, several thin linear end dielectric poles 11a and 11b parallel to the longitudinal directions Ca and Cb, respectively, flow of the electron showers Da and Db. It is electrically connected to the dielectric poles 4a and 4b so as not to cause resistance, and may have any cross-sectional shape such as round material, flat material, wire material, etc., but its surface is smooth and the electronic shower Da and Db. It is more desirable in terms of increasing the dielectric performance of the electron shower and enhancing the traveling ability of the electron showers Da and Db without hindering the flow.

  Further, the discharge electrodes 6a and 6b may be sandwiched by needle-like protrusions 10a and 10b, or may be welded or other joints. In the embodiment of the present invention, the discharge electrodes 6a and 6b and the dielectric poles 4a and 4b are about 40 mm, and the discharge electrodes 6a and 6b have dielectric spaces Ba and Bb of 80 mm, respectively. When the longitudinal directions 7a and 7b of the poles 4a and 4b are 850 mm and the lengths 12a and 12b parallel to the center lines 5a and 5b are 100 mm, respectively, a negative charge of 20,000 volts is supplied to the discharge electrodes 6a and 6b. The same positive charge of 20,000 volts is supplied to the dielectric poles 4a and 4b. If the voltage is further increased, plasma discharge occurs in the space, the current increases, and the state becomes unstable. Further, at a low voltage, there are few emitted electrons and a desired amount of generated electrons cannot be obtained.

  Next, an embodiment of “claim 2” will be described with reference to FIG. 3. Each dielectric is so formed as to intersect with each other on an extension of a common center line 5 a and 5 b of the discharge electrodes 6 a and 6 b and the dielectric electrodes 4 a and 4 b. The discharge electrodes 6a and 6b arranged on the poles 4a and 4b and the center lines 5a and 5b are extended in directions Ca and Cb perpendicular to the directions in which the dielectric spaces Ba and Bb and the discharge electrodes 6a and 6b face each other. Constant lengths 7a and 7b are formed so as to intersect each other on the extended lines of the center lines 5a and 5b, and the planar electron showers Da and Db penetrating toward the centers of the dielectric spaces Ba and Bb respectively provided. In order to induce and form a single film-shaped electron shower that merges by crossing and joining at the point E on the radial direction line, the discharge electrodes 5a and 5b and the dielectric are adjusted in order to arbitrarily adjust and maintain the position adjustment of the point E of the crossing point. Poles 4a and 4b, For example, the hinge pin 13 and the hinge arms 14a and 14b are provided on the dielectric poles 4a and 4b, and the set arms 15a and 15b are set on the other side of the dielectric poles 4a and 4b at the deflection center sharing the cores 5a and 5b. What is necessary is just to make it fix suitably to the elongate hole of both ends of flame | frame Ra, Rb with the volt | bolt etc. which are not shown in figure, and the implementation method of arbitrary sets can employ | adopt well-known various forms, and is not limited to drawing illustration. .

  A known power supply device can be applied to the high-voltage power supply device that charges the discharge electrodes 6a and 6b and the dielectric electrodes 4a and 4b.

  4 and 5 show another embodiment of the present invention. FIG. 5 shows a cross-sectional view taken along the line YY of FIG. A safety grill 21 that can be circulated is provided, and on the other side, frame-shaped dielectric poles 4a and 4b without an elongated bottom, and dielectric pole frames 24a and 24b are connected to the safety grills 22a and 22b via insulating fasteners 25a and 25b. At the same time, it is attached so that it can be accommodated in the case by a grill attachment 23 using a screw or a locking lever. The discharge electrodes 6a and 6b are not shown on the extensions of the center lines 5a and 5b of the dielectric poles 4a and 4b, but are attached to the dielectric poles 4a and 4b while maintaining insulation, and are used for the discharge electrodes provided in the case 20 The elastic contacts 16a and 16b and the dielectric electrode elastic contacts 17a and 17b are connected so that the discharge electrodes and the dielectric electrodes are electrically connected to each other when they are housed in the case. .

  Insulating fasteners 25a and 25b, dielectric pole frames 24a and 24b, safety grills 22a and 22b, grill attachment 23, and the like are shown in FIGS.

  A high voltage power supply device 18 is housed in the case 20, and necessary voltages are distributed to the aforementioned discharge electrode elastic contacts 16 a, 16 b and dielectric electrode elastic contacts 17 a, 17 b by wires (not shown). Necessary electric operation parts such as a switch and a volume knob for operating the high-voltage power supply unit are provided outside the case 20.

  Further, the other side surface of the case 20 is attached with a hanging tool or a mounting tool to a wall or the like as required, but it must be considered not to close the safety grills 22a and 22b on both sides. In the practice of the present invention, in order to obtain a better effect, the advancing component of the electronic curtain expands into the induced airflow and is attenuated by dispersion, and the suction component is low at a distance where the advancing component of the electronic curtain exists. In other words, it is not indispensable to install an exhaust system with low suction performance if necessary, but it is not an indispensable requirement.

  The most important feature of the present invention is that the electronic curtain itself is invisible, has no shape, does not even feel the flow of air, and is capable of shielding the necessary space with a gentle and transparent flow of electrons. . Therefore, in the present invention, when the main body of the embodiment is installed between the space to be cut off, for example, above or on the ceiling, and the electron curtain is emitted downward, the emitted electron ions are not visible. There is a transparent curtain between the other side, but the flow of air cannot come and go freely, so for example, elimination of odors, bad odors, smoke, airborne particles etc. present in the air, deactivation of bacteria Blocking can be performed in a quiet environment such as bacteria. However, the electronic curtain of the present invention relies only on the flow of electrons, so there are no wind turbines, fan-like airflows and wind pressures using electric motors, etc. The effect of the present invention can be exerted by applying to very few places.

  For example, the counter-facing seats with a view to the kitchen, the smell of the dining table between them does not flow to the seats, the smell of various seats, even the smoke of cigarettes is completely on the ceiling of the electronic curtain of the present invention If there is no kitchen, there is no forced exhaust such as a fan in the meantime, so there is no wind and the power is extremely small. Of course, the conventional ventilation fan only for the kitchen or on the audience side may be installed as it is for the original purpose. Although it is a familiar example, there is no sound at all, so it is quiet, there is no odor or smoke, and the electronic curtain can embody a mysterious world without any obstacles to the movement of goods, this example The features of the present invention can be explained in an easy-to-understand manner.

  In other words, the present invention does not use power, and there is no driving noise, unpleasant noise, etc., for example, to cut off from cooking kitchen rooms, smoking rooms, chemical rooms, locations where mist, steam, dust, etc. are generated. Can be obtained very economically in a quiet environment. Moreover, even if it touches a human body etc., there is no presence and it does not give a person a discomfort at all.

  In addition, by applying the ability to variably deflect the outflow direction of electrons in parallel arrangement of multiple rows of electronic curtains, which is a feature of the present invention, it is possible to arbitrarily deflect the flow direction of the electronic curtain after cross-joining without changing the installation position of the electronic curtain. . This means that if there is a slight airflow inherent to the installation location of the electronic curtain, the necessary airflow can be controlled against the flow or without installing a special device in accordance with the flow. Can be created.

  The implementation of the present invention is large-scale, for example, medical treatment field, pharmaceutical manufacturing management field, precision processing field, food manufacturing and storage field, deodorizing room, perfume manufacturing and blending field, etc. The possibility of industrial use will be greatly expanded, for example, by expanding the application to so-called clean room applications.

  In addition, even when exhaust of foreign substances contained in the air attracted by the flow of electrons in the electronic curtain is required, a small exhaust system is sufficient, so noise and discomfort associated with its operation are minimized. It is possible to provide a "people-friendly" economically extremely effective environment.
