Description

  The present invention relates to an ion generating apparatus including a discharge unit that generates positive or negative ions.

  In recent years, an ion generator that generates both positive ions and negative ions in a predetermined space and cleans the air in the space has been developed and put into practical use. The ion generator generates positive ions and negative ions in a target space, and these ions adhere to airborne bacteria and harmful substances in the air to cause a chemical reaction to generate hydrogen peroxide, hydroxyl radicals, etc. The active species are generated, and the fungus, Escherichia coli, suspended bacteria, etc. in the air in the space are removed by the action of decomposing the active species.

  Such an ion generator uses a method of discharging generated ions into the space using a blower fan, and an air flow excited by the migration of the generated ions without using a blower fan, so-called ion wind. There are ion diffusion methods to be released.

  FIG. 8 is a schematic diagram showing the distribution of ions released in a conventional diffusion ion generator. The conventional diffusion type ion generator includes a positive discharge needle 30b that generates positive ions, a negative discharge needle 30a that generates negative ions, and a voltage that applies a positive voltage and a negative voltage to the positive discharge needle 30b and the negative discharge needle 30a, respectively. And an application circuit 20. When a positive voltage and a negative voltage are respectively applied to the positive discharge needle 30b and the negative discharge needle 30a, positive ions and negative ions are generated and released from the positive discharge needle 30b and the negative discharge needle 30a, respectively. In this case, as shown in FIG. 8A, single ion regions 60 and 70 in which only one of positive ions and negative ions exists and a mixed region 50 in which positive ions and negative ions are mixed are formed. . Such a mixed region 50 varies depending on the distance between the positive discharge needle 30b and the negative discharge needle 30a. That is, as shown in FIG. 8B, when the distance between the positive discharge needle 30b and the negative discharge needle 30a is shortened, the mixed region 50 is expanded, but between the positive discharge needle 30b and the negative discharge needle 30a. When the distance becomes longer (FIG. 8A), the mixed area 50 is reduced.

  On the other hand, Patent Document 1 includes an ion generator provided with a positive discharge needle and a negative discharge needle that are appropriately separated, and discharges ions generated from the ion generator toward the passenger in the vehicle, thereby charging the passenger. We have proposed a vehicle static eliminator that eliminates static electricity.

Patent Document 2 proposes a static eliminator in which a partition plate is provided between a positive discharge needle and a negative discharge needle that are appropriately separated. The positive ions and negative ions generated from the positive discharge needle and the negative discharge needle are attracted to each other by the Coulomb force and recombined, and the generated ions may disappear. Such recombination between opposite ions is more likely to occur in the vicinity of a positive discharge needle and a negative discharge needle having a high ion concentration. The static eliminator of Patent Document 2 includes the partition plate, and suppresses the disappearance of ions due to such recombination of ions.

  However, in order to neutralize static electricity in the vehicle static eliminator of Patent Document 1, it is necessary to ensure a wide mixed area. In order to ensure a wide mixed area, as described above, the positive discharge needle and It is necessary to shorten the distance between the negative discharge needles. However, the vehicle static eliminator of Patent Document 1 cannot shorten the distance between the positive discharge needle and the negative discharge needle to a predetermined value or less. FIG. 9 is a schematic diagram showing the distribution of the electric lines of force 80, 80, 80. is there. (In FIG. 9, the electric force line 80 is indicated by using a dotted line.) The vehicle static eliminator of Patent Document 1 has a positive voltage applied to the positive discharge needle 302 and the negative discharge needle 301, and the positive discharge needle 302 and the negative discharge needle 301. And a voltage application circuit 21 for applying a negative voltage. However, when the distance between the positive discharge needle 302 and the negative discharge needle 301 becomes shorter than a predetermined value, the electric field strength increases when the distribution density of the electric force lines 80, 80, 80. Since S occurs, there is a problem in that the distance between the positive discharge needle 302 and the negative discharge needle 301 cannot be reduced below the predetermined value, and the miniaturization of the apparatus itself is limited.

  Further, the static eliminator of Patent Document 2 has a problem that generated ions collide with the partition plate and disappear. FIG. 10 is a schematic diagram showing the release of ions in the static eliminator of Patent Document 2. In FIG. The static eliminator of Patent Document 2 includes a positive discharge needle 304 and a negative discharge needle 303, a partition plate 40 disposed between the positive discharge needle 304 and the negative discharge needle 303, and a positive voltage across the positive discharge needle 304 and the negative discharge needle 303. And a voltage application circuit 22 for applying a negative voltage respectively. Positive ions and negative ions generated from the positive discharge needle 304 and the negative discharge needle 303 are released into the air by an ion wind. In this case, some of the released positive ions and negative ions collide with the partition plate and disappear. The disappearance of ions due to the collision with the partition plate may reduce the amount of ions and cause a reduction in charge removal performance.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a partition member disposed between the first discharge portion and the second discharge portion where positive or negative ions are generated. In the vicinity, a first conductive member having the same polarity as the ions emitted by the first discharge part, and a second conductive member having the same polarity as the ions emitted by the second discharge part are provided, and the first discharge part and the second By suppressing the approach of the ions generated from the discharge part to the partition member using the repulsive force of the same polarity between the first conductive member or the second conductive member and the ions, recombination of ions, the partition The distance between the first discharge part and the second discharge part can be shortened without reducing the amount of ions due to collision with a member, etc., and the apparatus can be downsized, and a blower fan is not used. In addition, it is possible to efficiently release ions. To provide a down generator.

  An ion generator according to the present invention includes a first discharge unit and a second discharge unit that generate positive or negative ions, and a partition member disposed between the first discharge unit and the second discharge unit. In the ion generator, a first conductive member disposed between the partition member and the first discharge part, having the same polarity as the ions generated by the first discharge part and repelling the ions, and the partition And a second conductive member disposed between the member and the second discharge part and having the same polarity as ions generated by the second discharge part and repelling the ions.

  In the present invention, since the first conductive member and the second conductive member have the same polarity as the first discharge part and the second discharge part, respectively, they are generated and emitted from the first discharge part and the second discharge part. When the ions to be moved approach the partition member, the partition member is repelled by the first conductive member and the second conductive member respectively disposed between the partition member and the first discharge portion or the second discharge portion. Move away from. Therefore, the generated ions are prevented from colliding with the partition member and disappearing. In addition, the approach to the partition member between ions of opposite polarity is suppressed, and the disappearance of ions due to recombination of ions is prevented.

  The ion generator according to the present invention is characterized in that the first conductive member and the second conductive member have the same potential as the first discharge unit and the second discharge unit, respectively.

  In the present invention, the first conductive member is configured to have the same potential as the first discharge part, and the second conductive member is configured to have the same potential as the second discharge part. For example, the first discharge Ion migration that can occur when there is a potential difference between the first portion and the first conductive member (or the second discharge portion and the second conductive member) is prevented.

  In the ion generator according to the present invention, the partition member, the first conductive member, and the second conductive member are plate-shaped, and the first conductive member and the second conductive member are within a contour in a direction perpendicular to the surface of the partition member. It is characterized by opposing so that a member may be settled.

  In the present invention, the partition member, the first conductive member, and the first conductive member are arranged so that the first conductive member and the second conductive member are within the contour of the partition member in a direction perpendicular to the surface of the partition member. Since the two conductive members are arranged to face each other, the shortest distance along the surface of the partition member from the first conductive member to the second conductive member, that is, a so-called creepage distance is sufficiently secured, and the first conductive member The spark discharge between the member and the second conductive member is suppressed.

  The ion generator which concerns on this invention is equipped with the box in which the said partition member, the 1st conductive member, and the 2nd conductive member were provided in one outer surface, The said 1st conductive member and the 2nd conductive member are the said partition members It has the partition side part distribute | arranged along the surface of this, and the box side part distribute | arranged along the said one surface of the said box, and is extended in the said partition side part, It is characterized by the above-mentioned.

  In this invention, when the ion which generate | occur | produces and discharge | releases from the said 1st discharge part and a 2nd discharge part approaches the said one surface of the said partition member or the said box, the said 1st conductive member and a 2nd conductive member It is repelled by each partition side and box side and moves away from the one side of the partition member and box. Therefore, the generated ions are prevented from colliding with the partition member and the one surface of the box and disappearing.

  The ion generator according to the present invention is characterized in that the first discharge part and the second discharge part are configured to alternately generate ions of opposite polarities.

  In the present invention, the first discharge part and the second discharge part alternately generate ions of opposite polarity, and in the region where only unipolar ions near the first discharge part and the second discharge part exist. By changing the polarity of the emitted ions, the bias of the ion species present in the region is improved. Further, charging of the dust existing in the region is suppressed, and the charged dust is prevented from adhering to the first discharge unit and the second discharge unit.

  The ion generator according to the present invention is characterized in that the first discharge part and the second discharge part have a period in which ions of the same polarity are generated.

  In the present invention, the ions emitted from the first discharge part and the second discharge part have the same polarity during the period, and repulsion of the same polarity occurs between these ions, so that they are emitted to a farther distance. It becomes possible to do.

  According to the present invention, the approach of the ions generated from the first discharge part and the second discharge part to the partition member is caused by the repulsive force between the same polarities of the first conductive member or the second conductive member and the ions. Therefore, the recombination of ions and the collision between the partition member and the ions can be prevented, and the distance between the first discharge part and the second discharge part can be shortened without reducing the amount of ions due to these. In addition, the apparatus can be downsized and ions can be efficiently discharged without using a blower fan.

  Hereinafter, an ion generator according to the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a configuration diagram showing a main configuration of an ion generator according to Embodiment 1 of the present invention, and FIG. 2 is a perspective view of the ion generator according to Embodiment 1 of the present invention. The ion generator according to Embodiment 1 of the present invention includes a first discharge needle 3a (first discharge part) and a second discharge needle 3b (second discharge part) capable of generating positive ions and negative ions, and a first discharge. A partition member 4 disposed between the needle 3a and the second discharge needle 3b and a voltage application circuit 2 that applies a positive voltage or a negative voltage to the first discharge needle 3a and the second discharge needle 3b, respectively. .

  Between the 1st discharge needle 3a and the partition member 4, the 1st electroconductive member 9a which repels the ion which generate | occur | produces from the 1st discharge needle 3a is arrange | positioned, Between the 2nd discharge needle 3b and the partition member 4, A second conductive member 9b that repels ions generated from the second discharge needle 3b is provided.

  The voltage application circuit 2 is accommodated in a rectangular parallelepiped box 1. A first discharge needle 3a and a second discharge needle 3b, a partition member 4, a first conductive member 9a and a second conductive member 9b are attached to one outer surface of the box 1.

  The first discharge needle 3a and the second discharge needle 3b are substantially conical, and the partition member 4 is a rectangular plate. The 1st discharge needle 3a and the 2nd discharge needle 3b have electroconductivity, and the partition member 4 has insulation. The partition member 4 protrudes from the one outer surface of the box body 1 so as to block between the first discharge needle 3a and the second discharge needle 3b.

  FIG. 3 is a schematic diagram showing the distribution of lines of electric force of the ion generator according to Embodiment 1 of the present invention. In the ion generator according to Embodiment 1 of the present invention, the partition member 4 is provided so as to block between the first discharge needle 3a and the second discharge needle 3b. Only field lines will be formed. Thus, by arranging the partition member 4 between the first discharge needle 3a and the second discharge needle 3b, the first discharge needle that occurs when the distance between the first discharge needle 3a and the second discharge needle 3b is short. It is possible to prevent recombination due to Coulomb force between ions of opposite polarity generated from 3a and second discharge needle 3b and occurrence of spark discharge due to an increase in electric field strength between first discharge needle 3a and second discharge needle 3b. it can. Therefore, the distance between the first discharge needle 3a and the second discharge needle 3b can be shortened, and the ion generator can be downsized.

  FIG. 4 is a schematic diagram showing the relationship between the arrangement and size of the partition member 4 and the first conductive member 9a of the ion generator according to Embodiment 1 of the present invention. In the drawing, only the first conductive member 9a is illustrated. The first conductive member 9a and the second conductive member 9b are plate-like conductors made of a metal such as stainless steel.

  The first conductive member 9a is disposed along the one side of the partition body 4 along the one surface of the partition member 4 and the one outer surface of the box body 1, and is disposed on the box body 1 side of the partition side portion 91a. And a box side portion 92a extending to the edge. The partition side portion 91a and the box side portion 92a are integrally formed, and the partition side portion 91a is attached so as to be in contact with the one surface of the partition member 4 and the box side portion 92a is in contact with the one outer surface of the box body 1. It has been. The partition side portion 91a has a substantially semicircular shape, and the box side portion 92a has a rectangular shape. A first discharge needle 3a projects from the box side portion 92a in the thickness direction at the end portion in the longitudinal direction of the box side portion 92a.

  On the other hand, the second conductive member 9b is disposed along the other side surface of the partition member 4 along the other surface 91b and the one outer surface of the box body 1, and the box body of the partition side portion 91b. And a box side portion 92b extending to the edge on the one side. The partition side portion 91b and the box body side portion 92b are integrally formed. The partition side portion 91b is in contact with the other surface of the partition member 4, and the box body side portion 92b is in contact with the one outer surface of the box body 1. It is attached. The partition side part 91b has a substantially semicircular shape, and the box side part 92b has a rectangular shape. Further, the second discharge needle 3b projects from the box side portion 92a in the thickness direction at the end portion in the longitudinal direction of the box side portion 92a.

  In other words, the partition member 4, the first conductive member 9a, and the second conductive member 9b are arranged in parallel so as to face each other, and the partition member 4 blocks between the first conductive member 9a and the second conductive member 9b. It is attached as follows. Further, the partition member 4 is larger than the first conductive member 9a and the second conductive member 9b, and the first conductive member 9a and the second conductive member 9b are within the outline of the partition member 4 in the direction perpendicular to the surface of the partition member 4. The partition member 4, the first conductive member 9a, and the second conductive member 9b are configured so as to be accommodated. Therefore, the shortest distance along the surface of the partition member 4 from the first conductive member 9a to the second conductive member 9b, that is, a so-called creepage distance is sufficiently secured, and the electric power between the first conductive member 9a and the second conductive member 9b is secured. Attains electrical insulation and suppresses spark discharge.

  That is, the first conductive member 9a and the second conductive member 9b are disposed with the partition member 4 interposed therebetween, and the distance between the first conductive member 9a and the second conductive member 9b is only the thickness of the partition member 4. . In such a case, if the partition member 4 is not provided, or if the partition member 4 is smaller than the first conductive member 9a and the second conductive member 9b, the space between the first conductive member 9a and the second conductive member 9b is used. There is a risk that spark insulation may occur because electrical insulation is not secured. However, as described above, the first conductive member 9a and the second conductive member 9b have a size that can be accommodated in the outline of the partition member 4 in the direction perpendicular to the surface of the partition member 4, and therefore the creeping distance is sufficient. It is possible to achieve electrical insulation between the first conductive member 9a and the second conductive member 9b and to suppress spark discharge.

  Further, the first conductive member 9a and the second conductive member 9b are connected to the voltage application circuit 2, and voltages having the same potential as the potential applied to the first discharge needle 3a and the second discharge needle 3b are respectively applied. It is configured as follows. Accordingly, the first conductive member 9a and the second conductive member 9b have the same potential and the same polarity as the first discharge needle 3a and the second discharge needle 3b, respectively, and the ions generated from the first discharge needle 3a are the first. The ions generated from the second discharge needle 3b with respect to the conductive member 9a have a repulsive force with respect to the second conductive member 9b.

  The first conductive member 9a and the second conductive member 9b are configured to synchronize with voltage application to the first discharge needle 3a and the second discharge needle 3b. That is, the first conductive member 9a and the second conductive member 9b are configured to always have the same potential and the same polarity as the first discharge needle 3a and the second discharge needle 3b.

  Further, the first conductive member 9a and the second conductive member 9b are configured to have the same potential as the first discharge needle 3a and the second discharge needle 3b, respectively, so the first discharge needle 3a and the first conductive member 9a, or the problem that may occur when there is a potential difference between the second discharge needle 3b and the second conductive member 9b, that is, the problem that ions generated at either low potential move, Release can be performed.

  Hereinafter, the behavior of ions generated in the ion generator according to Embodiment 1 of the present invention will be described. FIG. 5 is an explanatory view for explaining the behavior of ions generated in the ion generator according to the present invention.

  Hereinafter, the voltage application circuit 2 applies a negative voltage having the same potential to the first discharge needle 3a and the first conductive member 9a, and applies a positive voltage having the same potential to the second discharge needle 3b and the second conductive member 9b. An example will be described. For convenience of explanation, the space on the first discharge needle 3a side is abbreviated with respect to the partition member 4 and the second discharge needle is abbreviated with the space on the second discharge needle 3b side with respect to the partition member 4. It is called 3b side.

  When a negative voltage is applied to the first discharge needle 3a and the first conductive member 9a by the voltage application circuit 2, and a positive voltage is applied to the second discharge needle 3b and the second conductive member 9b, the first discharge needle 3a. Negative ions are generated, and positive ions are generated from the second discharge needle 3b. The negative ions and positive ions are released and diffused to the first discharge needle 3a side and the second discharge needle 3b side, respectively.

  In this case, some of the negative ions on the first discharge needle 3 a side and some of the positive ions on the second discharge needle 3 b side move toward the one surface of the partition member 4 and the box 1. However, the negative ions moving toward the partition member 4 are rebounded by the partition side portion 91a of the first conductive member 9a before colliding with the partition member 4, and are moved toward the one surface of the box 1 Is rebounded by the box side portion 92a of the first conductive member 9a before colliding with the one surface of the box body 1. This is because a voltage having the same potential as the first discharge needle 3a is applied to the first conductive member 9a and has the same potential and the same polarity as the first discharge needle 3a. This is because repulsive forces between the same poles occur. This also applies to positive ions moving toward the partition member 4, and the positive ions are separated from the partition member 4 and the box by the repulsive force between the same polarity between the second conductive member 9 b and the positive ions. Before colliding with the one surface, the first conductive member 9b is rebounded by the partition side portion 91b and the box body side portion 92b.

  Therefore, the ion generator according to Embodiment 1 of the present invention can prevent the generated ions from disappearing by colliding with the partition member 4 and the one surface of the box 1, and the amount of ions due to the disappearance can be reduced. It is possible to prevent a decrease in performance due to a decrease and a decrease in the amount of ions. Furthermore, since the vicinity of the opposite polarity partition member 4, that is, the opposite ions are suppressed from approaching each other, the disappearance of ions due to recombination of the opposite polarity ions in the vicinity of the partition member 4 is prevented.

Hereinafter, the bactericidal action of positive ions and negative ions generated in this way will be described. For convenience of explanation, H ⁺ (H ₂ O) _m (m is an arbitrary natural number) is generated as a positive ion, and O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) is generated as a negative ion. An example of the case will be described. When H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n adhere to the surface of airborne bacteria or harmful substances in the air, a chemical reaction occurs and hydrogen peroxide (H ₂ O, which is an active species), is generated. ₂ ) or hydroxyl radicals (.OH) are generated respectively. These active species perform an action of oxidizing and decomposing odor molecules in the air, a bactericidal action for surrounding and killing airborne bacteria in the air, and the like.

  FIG. 6 is a graph showing an example of a voltage application pattern by the voltage application circuit 2 in the ion generator according to Embodiment 1 of the present invention. The vertical axis of the graph in FIG. 6 indicates voltage (V), and the horizontal axis indicates elapsed time (t). At the time of voltage application start (t0) by the voltage application circuit 2, first, a positive voltage is applied to the first discharge needle 3a, and a negative voltage is applied to the second discharge needle 3b. The application of a positive voltage to the first discharge needle 3a and the application of a negative voltage to the second discharge needle 3b are continuously performed until t1 after Δt time from t0. Thereafter, when the elapsed time reaches t1, a negative voltage is applied to the first discharge needle 3a, and a positive voltage is applied to the second discharge needle 3b. This continues until t2 after Δt time from t1. Thereafter, when the elapsed time reaches t2, a positive voltage is applied again to the first discharge needle 3a, and a negative voltage is applied again to the second discharge needle 3b. Such voltage application is repeated. That is, the ion generator according to Embodiment 1 of the present invention is configured to repeatedly apply positive and negative voltages alternately at predetermined time intervals, in other words, periodically.

  By alternately applying positive and negative voltages to the first discharge needle 3a and the second discharge needle 3b, the first discharge needle 3a and the second discharge needle 3b alternately generate ions having opposite polarities. Become. Therefore, on the first discharge needle 3a side and the second discharge needle 3b side, the polarity of the ions released to the one-ion region where only one-polar ion exists (for example, the regions 60 and 70 in FIG. 8) is changed. It is possible to improve the bias of ion species existing in the one-ion region. Moreover, since a positive voltage and a negative voltage are alternately applied, charging of dust existing in the one-ion region is suppressed, and the charged dust adheres to the first discharge needle 3a and the second discharge needle 3b. Reduce.

  In the above description of the first embodiment, the case where the first conductive member 9a and the second conductive member 9b are disposed so as to be in contact with the partition member 4 has been described as an example, but the present invention is not limited thereto. For example, the same effect can be obtained even when the first conductive member 9a and the second conductive member 9b are appropriately separated from the partition member 4 and are respectively disposed between the partition member 4 and the first discharge needle 3a or the second discharge needle 3b. Can be obtained.

(Embodiment 2)
FIG. 7 is a graph showing an example of a voltage application pattern by the voltage application circuit 2 in the ion generator according to Embodiment 2 of the present invention. The vertical axis of the graph in FIG. 7 indicates voltage (V), and the horizontal axis indicates elapsed time (t). In the ion generator according to Embodiment 2, a positive voltage and a negative voltage are alternately applied to the first discharge needle 3a and the second discharge needle 3b in a predetermined cycle, but the voltage is applied to the first discharge needle 3a. The period and the voltage application period to the second discharge needle 3b are configured to deviate by a predetermined time, and the first discharge needle 3a and the second discharge needle 3b periodically have a period in which ions of the same polarity are generated. .

  For example, when the voltage application circuit 2 starts voltage application (t0), a positive voltage is applied to the first discharge needle 3a and the second discharge needle 3b. Thereafter, a negative voltage is applied to the first discharge needle 3a and the second discharge needle 3b. The negative voltage is applied to the first discharge needle 3a at a time t1 after lapse of Δt time from t0. For the second discharge needle 3b at t1 / 2 after ½ Δt time has elapsed from t0. That is, the negative voltage is applied to the second discharge needle 3b earlier than the first discharge needle 3a by ½Δt. Therefore, in the time range from t0 to t1 / 2 (between 1 / 2Δt), the first discharge needle 3a and the second discharge needle 3b generate the same polarity ions (positive ions).

  Thereafter, in the first discharge needle 3a, the negative voltage is continuously applied from t1 to t2 after Δt time, and the positive voltage is applied again when the elapsed time is t2. On the other hand, in the second discharge needle 3b, the negative voltage is continuously applied from t1 / 2 to t3 / 2 after Δt time, and the positive voltage is applied again when the elapsed time is t3 / 2. That is, the positive voltage is applied to the second discharge needle 3b earlier than the first discharge needle 3a by ½Δt. Therefore, within the time range from t1 to t3 / 2 (between 1 / 2Δt), the first discharge needle 3a and the second discharge needle 3b generate ions of the same polarity (negative ions).

  Thus, the ion generation neglect according to Embodiment 2 of the present invention periodically has a period (1/2 Δt) in which the first discharge needle 3a and the second discharge needle 3b generate ions of the same polarity. Inside, since repulsion of the same polarity occurs in the ions generated from the first discharge needle 3a and the second discharge needle 3b, it becomes possible to discharge (diffusion) farther away, without providing a blower fan, It is possible to efficiently release ions using an ion wind.
