Description

  The present invention relates to an ion generator and an electrical apparatus including the ion generator.

  Conventionally, ion generators have been used to purify, sterilize, or deodorize indoor air.

  Generally, an ion generator includes a discharge electrode that generates ions by discharge. In the ion generator, for example, ions are generated by generating corona discharge between the tip of the discharge electrode to which a high voltage is applied and the induction electrode.

  As such a discharge electrode that generates ions by applying a high voltage, a brush-like discharge electrode in which the roots of a plurality of fibrous conductors are bundled is known.

  For example, in Patent Document 1, a part of a bundle of carbon fibers is extended by a predetermined length from one end of a metal pipe, and the metal pipe is fixed by crimping to the other end of the bundle of carbon fibers. A brush-like discharge electrode is disclosed.

JP2003-229232A (released on August 15, 2003)

  In such a brush-like discharge electrode, when a high voltage is applied, the conductors on the unbundled side, which become the tip side of the conductors, are electrically repelled and spread. For this reason, when such a brush-like discharge electrode is used, the amount of ions generated when the same voltage is applied is increased as compared with the case where a needle-like discharge electrode is used. As a result, good ion emission can be performed.

  However, such a brush-like discharge electrode has a problem that it is easily deformed by using a fibrous, that is, linear conductor. For example, in a manufacturing process or the like, when the ion generator using such a brush-like discharge electrode falls and the discharge electrode comes into contact with the floor or the like, there is a problem that the brush portion is crushed.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to protect the conductor in the event of a fall of an ion generator using a discharge electrode formed by bundling linear conductors. An object of the present invention is to provide an ion generator and an electric device including the ion generator.

  In order to solve the above-described problem, an ion generator according to one embodiment of the present invention includes a substrate and a tip portion that is held by the substrate so as to protrude from the surface of the substrate and includes a plurality of linear conductors. And a base end portion to which the plurality of conductors are attached, at least one discharge electrode for generating ions by discharge, and the discharge electrode with respect to the substrate so as to be adjacent to the discharge electrode. And at least one projecting member provided so as to project from the tip portion.

  In order to solve the above-described problems, an electrical device according to one embodiment of the present invention includes the above-described ion generator.

  According to one aspect of the present invention, an ion generator using a discharge electrode formed by bundling linear conductors and capable of protecting the conductor in the event of a fall or the like, and the ion generator It is possible to provide an electrical apparatus including

Embodiment 1
First, an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view showing a schematic configuration of an ion generator according to the present embodiment, and FIG. 2 is a front view, a plan view, and a side view showing a schematic configuration of the ion generator.

  As shown in FIGS. 1 and 2, the ion generator 1 of the present embodiment includes a rectangular case 10 (housing), a transformer driving circuit substrate 12, a high-voltage transformer 13, and an ion generating element substrate 14. The lid body 15, the discharge electrodes 21 and 22, and the protection plates 51 and 52 (protruding members) are provided.

  The case 10 has a box shape with an open front surface and an upper surface, and is formed of an insulating resin. An external connection substrate 11 is attached to the front portion of the case 10. Further, in the case 10, a transformer driving circuit substrate 12, a high-voltage transformer 13, and an ion generating element substrate 14 are accommodated in order from the front. A lid 15 is provided on the upper surface of the case 10 so as to cover the external connection substrate 11, the transformer drive circuit substrate 12, and the high-voltage transformer 13.

  A plurality of (for example, six) connection terminals 16 are provided on the surface of the external connection substrate 11. Each of the plurality of connection terminals 16 is formed of a conductive film formed on the surface of the external connection substrate 11 and is formed by, for example, a printing pattern, plating, sputtering, CVD (Chemical Vapor Deposition), or the like. This conductive film is made of a material such as copper (Cu), aluminum (Al), gold (Au), or an alloy thereof, and has a film thickness on the order of several tens of μm (for example, a film thickness of 35 μm). Have. Each connection terminal 16 is disposed so as to be exposed to the outside of the case 10 in a state where the external connection substrate 11 is supported by the case 10.

  A high voltage transformer driving circuit is disposed on the transformer driving circuit substrate 12. This high-voltage transformer drive circuit is for driving the high-voltage transformer 13 by an external input voltage.

  The high-voltage transformer 13 is driven by the high-voltage transformer drive circuit to boost the input voltage. An ion generating element is arranged on the ion generating element substrate 14. The ion generating element generates at least one of positive ions and negative ions when a voltage boosted by the high-voltage transformer 13 is applied.

  The ion generating element includes discharge electrodes 21 and 22 and annular induction electrodes 23 and 24. The discharge electrode 21 is attached to one side of the ion generating element substrate 14, and the induction electrode 23 is formed around the attachment position of the discharge electrode 21. The discharge electrode 22 is attached to the other side of the ion generating element substrate 14, and the induction electrode 24 is formed around the attachment position of the discharge electrode 22.

  The induction electrode 23 is an electrode for forming an electric field with the discharge electrode 21, while the induction electrode 24 is an electrode for forming an electric field with the discharge electrode 22. The discharge electrode 21 is an electrode for generating negative ions with the induction electrode 23, while the discharge electrode 22 is an electrode for generating positive ions with the induction electrode 24. The induction electrodes 23 and 24 are at ground potential.

  The surface of the ion generating element substrate 14 is covered with an insulating sealing material 41 as shown in FIG. The insulating sealing material 41 covers the insulating sealing material 41 to a position corresponding to the surface of the lid body 15 so as to be substantially flush with the surface of the lid body 15, for example. As the insulating sealing material 41, for example, an insulating material such as an epoxy resin or a urethane resin is used.

  The discharge electrodes 21 and 22 are provided vertically from the surface of the ion generating element substrate 14 and protrude from the surface of the insulating sealing material 41.

  The discharge electrode 21 includes a plurality of linear conductors 25, and is a brush-like discharge electrode including a distal end portion 31 formed in a brush shape and a base end portion 33 to which the plurality of conductors 25 are attached. is there. In addition, the discharge electrode 22 includes a plurality of linear conductors 26, and includes a brush-shaped discharge including a distal end portion 32 formed in a brush shape and a base end portion 34 to which the plurality of conductors 26 are attached. Electrode.

  Note that the tip portions 31 and 32 are provided on the conductors 25 and 26 from the portions ahead of the base end portions 33 and 34, specifically, from the tips 25a and 26a of the conductors 25 and 26 bundled in a brush shape. The part to the connection end (contact end) with the base end parts 33 and 34 is shown. The linear shape includes a thread shape, a fiber shape, and a wire shape.

  The tip portions 31 and 32 of the discharge electrodes 21 and 22 are made of a conductive material such as metal, carbon fiber, conductive fiber, conductive resin, or the like. The outer diameter per one of the plurality of conductors 25 and 26 at the tip portions 31 and 32 is 5 μm or more and 30 μm or less. By setting the outer diameter of the conductors 25 and 26 to 5 μm or more, the mechanical strength of the conductors 25 and 26 can be ensured and the electric wear of the conductors 25 and 26 can be suppressed. Further, by setting the outer diameter of the conductors 25 and 26 to 30 μm or less, the conductors 25 and 26 that bend like hair are formed, and the conductors 25 and 26 are likely to spread and swing.

  The conductors 25 and 26 may be carbon fibers having an outer diameter of 7 μm, respectively, or may be conductive fibers made of SUS (stainless steel) having an outer diameter of 12 μm or 25 μm.

  The base end portion 33 of the discharge electrode 21 is used for binding the sheet metal-like attachment portion 33a for attaching the discharge electrode 21 to the ion generating element substrate 14 and the plurality of conductors 25 at the distal end portion 31 at the connection end. Bundling portion 33b. Similarly, the base end portion 34 of the discharge electrode 22 includes a sheet metal-like attachment portion 34a for attaching the discharge electrode 22 to the ion generating element substrate 14 and a plurality of conductors 26 at the distal end portion 32 at the connection end. A bundling portion 34b for bundling.

  Next, the length of the distal end portion 31 of the discharge electrode 21 will be described with reference to FIG.

  FIG. 3 is a front view showing a schematic configuration of the discharge electrode 21 and the protection plate 51 shown in FIGS. 1 and 2, and the discharge electrode according to the voltage applied to the discharge electrode 21 (and between the induction electrodes 23). 21 shows how the shape of the tip portion 31 of 21 changes. Although not shown, the same applies to the discharge electrode 22.

  L <b> 1 shown in FIG. 3 indicates the length of the distal end portion 31 of the discharge electrode 21, that is, the length (projection length) in which the plurality of linear conductors 25 protrude from the base end portion 33. 3 indicates the length (protrusion length) at which the base end portion 33 of the discharge electrode 21 protrudes (exposes) from the lid 15, that is, the insulating sealing material 41.

  FIG. 3A shows a state in which no voltage is applied to the discharge electrode 21. At this time, the tips of the plurality of linear conductors 25 are closed at the tip 31 of the discharge electrode 21.

  FIG. 3B shows a state where a high voltage pulse is applied to the discharge electrode 21. At this time, since each of the plurality of conductors 25 is electrically repelled at the tip portion 31 of the discharge electrode 21 due to the same polarity, the conductor 25 is bent, and as a result, the tip of the brush is opened. It becomes a shape like this.

  On the other hand, positive ions are generated at the tips of the conductors 25, and as described above, the plurality of conductors 25 have a shape in which the tips of the brushes are open. Will increase. Therefore, the discharge electrode 21 of this embodiment increases the amount of ions generated when the same voltage is applied as compared to the needle-like discharge electrode.

  FIG. 3C shows a state where a higher voltage pulse is applied to the discharge electrode 21. At this time, since the electric repulsive force between the plurality of conductors 25 is increased at the distal end portion 31 of the discharge electrode 21, the shape is such that the distal end of the brush is further opened. Therefore, the amount of generated ions is further increased.

  By the way, the plurality of conductors 25 of the discharge electrode 21 are electrically attracted to the induction electrode 23 having a different polarity. For this reason, one or a plurality of the conductors 25 may be bent greatly toward the induction electrode 23 side.

  On the other hand, in the present embodiment, the protruding length L1 of the conductor 25 is smaller than the protruding length L2 of the base end portion 33. Therefore, even if the conductor 25 is electrically attracted to the induction electrode 23 and bent, or even if the conductor 25 is bent by a mechanical force such as a human touch, the conductive material 25 The body 25 does not contact the insulating sealing material 41. For this reason, abnormal discharge, current leakage, etc. occur at the contact portion where the conductor 25 is in contact with the insulating sealing material 41, and the amount of generated ions decreases or becomes zero. It is possible to reliably avoid problems that the drive circuit board 12, the high-voltage transformer 13, and the ion generating element board 14 are damaged due to abnormal discharge, current leakage, and the like, and that the noise value of the ion generator 1 increases. can do.

  Note that the lengths of the distal end portions 31 and 32 of the discharge electrode 21 (projection length L1 of the conductors 25 and 26) are set to be smaller than the projection length L2 of the base end portions 33 and 34 as described above. If it is, it will not be specifically limited. However, if the lengths of the tip portions 31 and 32 are too short, the conductors 25 and 26 are difficult to bend, so that the spread and swinging movement of the conductors 25 and 26 are reduced, and the effect of the brush-like discharge electrode is sufficient. I can't get it. Moreover, the ion generator 1 becomes large, so that the length of the front-end | tip parts 31 * 32 is lengthened. Therefore, the length of the tip portions 31 and 32 is desirably 3 mm or more. The lengths of the tip portions 31 and 32 may be 5 mm or more. Further, it is desirable that the protruding length L2 of the base end portions 33 and 34 is not more than 5 times the length of the distal end portions 31 and 32 (the protruding length L1 of the conductors 25 and 26).

  Next, the protection plates 51 and 52 will be described below with reference to FIGS.

  The ion generator 1 is mounted on a certain mounting table (not shown) in a state as shown in FIGS. 1 and 2 after it is manufactured and attached to various electric devices. Not exclusively. For example, there is a possibility that the above-described state is repeatedly placed on the mounting table. Thus, when the ion generator 1 falls in the manufacturing process or the like, the discharge electrodes 21 and 22 come into contact with the floor body (floor) such as the mounting table, and damage (deformation) such as the brush portion is crushed. May occur.

  Therefore, in the present embodiment, protective plates 51 and 52 for protecting the discharge electrodes 21 and 22 are provided so as to be adjacent to the discharge electrodes 21 and 22, respectively.

  In the present embodiment, the ion generating element substrate 14 provided with the protruding discharge electrodes 21 and 22 is provided at one end of the rear portion of the upper surface of the rectangular case 10.

  The ion generating element substrate 14 has a rectangular shape, and the discharge electrodes 21 and 22 are arranged along the longitudinal direction of the ion generating element substrate 14. The substrate 14 for ion generating elements is provided facing the side 10a so that the long side 14a, which is a side parallel to the arrangement direction of the discharge electrodes 21 and 22, is parallel to the side 10a at the rear of the case 10. ing.

  Therefore, in the present embodiment, protective plates 51 and 52 are provided so as to protrude from both side end portions of the rear portion on the upper surface of the case 10 so as to be adjacent to the discharge electrodes 21 and 22, respectively.

  The protective plates 51 and 52 are arranged in the longitudinal direction of the ion generating element substrate 14 (that is, the direction parallel to the long side 14a of the ion generating element substrate 14), which is the arrangement direction of the discharge electrodes 21 and 22.・ It is juxtaposed with 22 in between.

  The maximum value of the height of the protective plates 51 and 52 is larger than the height of the discharge electrodes 21 and 22, and the protective plates 51 and 52 have the tip portions 31 of the discharge electrodes 21 and 22 with respect to the surface of the substrate 14 for ion generating elements. -It protrudes vertically on the insulating sealing material 41 or by the upper part of the cover body 15 or integral molding so that it may protrude rather than 32.

  Thereby, even when the ion generator 1 falls, for example, it is possible to prevent the discharge electrodes 21 and 22 from coming into direct contact with an object outside the ion generator 1 such as the mounting table described above, and damage due to the contact can be prevented. .

  Here, the height of the protective plates 51 and 52 is the length in the vertical direction, that is, the height from the surface of the insulating sealing material 41 to the upper surface of the protective plate 51, and the surface of the insulating sealing material 41. To the upper surface of the protective plate 52.

  The height of the protective plates 51 and 52 is not particularly limited as long as the protective plates 51 and 52 are formed so as to protrude from the front end portions 31 and 32 of the discharge electrodes 21 and 22 with respect to the surface of the ion generating element substrate 14. .

  However, if the height of the protective plates 51 and 52 is increased, the ion generator 1 is increased in size accordingly. For this reason, the height of the protection plates 51 and 52 is such that, for example, when the ion generator 1 falls, the discharge electrodes 21 and 22 do not directly contact an object outside the ion generator 1 such as the mounting table. It is desirable to be formed at a height of. For example, the height from the surface of the insulating sealing material 41 to the upper surfaces of the protective plates 51 and 52 is the height from the surface of the insulating sealing material 41 to the tips of the tip portions 31 and 32 in the discharge electrodes 21 and 22. It is desirable that the height be slightly higher than the height (that is, the maximum height from the surface of the insulating sealing material 41 to the tips 25a and 26a of the conductors 25 and 26).

  Further, the protective plates 51 and 52 are discharged so that the distance between the discharge electrodes 21 and 22 and the protective plates 51 and 52 is longer than the lengths of the tip portions 31 and 32 of the discharge electrodes 21 and 22, respectively. The electrodes are spaced apart from the electrodes 21 and 22.

  For this reason, as shown in FIGS. 3B and 3C, the conductors 25 or 26 repel each other and the tip portions 31 and 32 spread, so that Even if it falls to an angle, the conductors 25 and 26 do not come into direct contact with the protective plates 51 and 52, and leakage can be prevented.

  The protection plates 51 and 52 are respectively protected when the discharge electrodes 21 and 22 are viewed through the protection plates 51 and 52 (that is, when the ion generator 1 is viewed from a direction parallel to the side 10a of the case 10). The plates 51 and 52 are formed in a plate shape in which portions facing the tip portions 31 and 32 of the discharge electrodes 21 and 22 are cut out. For this reason, the protective plate 51 is formed with an opening 51 a that faces the discharge electrode 21 and exposes the tip 31. On the other hand, the protective plate 52 is formed with an opening 52 a that faces the discharge electrode 22 and exposes the tip 32.

  Since the openings 51a and 52a are formed in the protective plates 51 and 52 as described above, the protective plates 51 and 52 do not hinder the release of ions by the discharge electrodes 21 and 22, and perform good ion discharge. Can do.

  In the present embodiment, the plate-like attachment portions 33a and 34a are attached to the ion generating element substrate 14 such that the normal direction of the plate surface is the front-rear direction. The conductors 25 and 26 are likely to fall in the direction in which the thickness of the sheet-like attachment portions 33a and 34a is thin, but are difficult to fall in the direction in which the thickness of the sheet-metal attachment portions 33a and 34a is thick. For this reason, the discharge electrodes 21 and 22 are easy to fall down in the front-rear direction but hard to fall down in the left-right direction. Therefore, the protective plates 51 and 52 provided in the left and right direction of the discharge electrodes 21 and 22 are not close to the conductors 25 and 26 of the discharge electrodes 21 and 22, and leakage can be effectively prevented.

  In other words, the plate-like attachment portions 33a and 34a of the discharge electrodes 21 and 22 are for the ion generating element so that the protective plates 51 and 52 do not exist in the normal direction of the plate surface from the attachment portions 33a and 34a. It is desirable that it is attached to the substrate 14.

(Modification)
In the present embodiment, the protective plates 51 and 52 are described as an example in the case where the discharge electrodes 21 and 22 are arranged in parallel in the longitudinal direction of the ion generating element substrate 14. It is not limited to this.

  Even if the ion generator 1 falls, for example, if a protective plate is formed at a position and height that can prevent the conductors 25 and 26 from directly contacting an object outside the ion generator 1, Only one protective plate may be provided.

  Further, in the present embodiment, the case where the ion generating element substrate 14 is provided in the rear portion of the case 10 is described as an example. However, the ion generating element substrate 14 is provided in the front portion of the case 10. It may be provided and may be provided in the central part.

  Further, in the present embodiment, the induction electrodes 23 and 24 are used, but even if this is omitted, positive ions and negative ions can be generated from the discharge electrodes 21 and 22. However, it is desirable to use the induction electrodes 23 and 24 because the electric field strength at the discharge electrodes 21 and 22 increases and the amount of ions generated increases.

[Embodiment 2]
Another embodiment of the present invention will be described mainly with reference to FIGS. In the present embodiment, differences from the first embodiment will be described.

  FIG. 4 is a perspective view showing a schematic configuration of the ion generator according to the present embodiment, and FIG. 5 is a front view, a plan view, and a side view showing a schematic configuration of the ion generator.

  In the ion generator 2 according to this embodiment, instead of the protective plates 51 and 52, protective plates 61 and 62 (protruding members) for protecting the discharge electrodes 21 and 22 are arranged in the direction in which the discharge electrodes 21 and 22 are arranged. In parallel with the discharge electrodes 21 and 22 in the short direction of the ion generating element substrate 14 (that is, the direction parallel to the short side 14b of the ion generating element substrate 14). In addition, the direction in which the mounting portions 33a and 33b of the discharge electrodes 21 and 22 are liable to fall is different, and a recess 90 is provided on the side surface of the case 10 instead of the external connection substrate 11, and a plurality of connections are made in the recess 90. Except for the point provided with the terminal 91, it has the same configuration as the ion generator 1 according to the first embodiment.

  The maximum value of the height of the protective plates 61 and 62 is larger than the height of the discharge electrodes 21 and 22, and the protective plates 61 and 62 have the tip portions 31 of the discharge electrodes 21 and 22 with respect to the surface of the substrate 14 for ion generating elements. -It protrudes vertically on the insulating sealing material 41 or by the upper part of the cover body 15 or integral molding so that it may protrude rather than 32.

  Thereby, also in this embodiment, even when the ion generator 2 falls, for example, it is possible to prevent the discharge electrodes 21 and 22 from coming into direct contact with an object outside the ion generator 2 such as the mounting table. Damage can be prevented.

  Here, the height of the protective plates 61 and 62 is the length in the vertical direction, that is, the height from the surface of the insulating sealing material 41 to the upper surface of the protective plate 61, and the surface of the insulating sealing material 41. To the upper surface of the protective plate 62. The upper surfaces of the protection plates 61 and 62 are specifically upper surfaces of beam portions 71 and 81 to be described later.

  In this embodiment as well, the height of the protective plates 61 and 62 is such that the height of the protective plates 61 and 62 protrudes from the front end portions 31 and 32 of the discharge electrodes 21 and 22 with respect to the surface of the ion generating element substrate 14. If it is formed in, it will not specifically limit.

  However, if the height of the protection plates 61 and 62 is increased, the ion generator 2 is increased in size accordingly. For this reason, the height of the protection plates 61 and 62 is such that, for example, when the ion generator 2 falls, the discharge electrodes 21 and 22 do not directly contact an object outside the ion generator 2 such as the mounting table. It is desirable to be formed at a height of. For example, the height from the surface of the insulating sealing material 41 to the upper surfaces of the protective plates 61 and 62 is the height from the surface of the insulating sealing material 41 to the tips of the tip portions 31 and 32 in the discharge electrodes 21 and 22. It is desirable that the height be slightly higher than the height (that is, the maximum height from the surface of the insulating sealing material 41 to the tips 25a and 26a of the conductors 25 and 26).

  The protective plates 61 and 62 are opposed to each other so that the distance between the discharge electrodes 21 and 22 and the protective plates 61 and 62 is longer than the lengths of the tip portions 31 and 32 of the discharge electrodes 21 and 22. Has been placed.

  That is, the distance between the protection plates 61 and 62 adjacent to each other is formed to be twice or more as long as the tip portions 31 and 32 of the discharge electrodes 21 and 22. For this reason, also in this embodiment, as shown in FIGS. 3B and 3C, the conductors 25 or 26 are repelled and the tip portions 31 and 32 are expanded, so that the conductors 25. Regardless of the angle at which the conductor 26 is tilted, the conductors 25 and 26 are not in direct contact with the protective plates 61 and 62, thereby preventing leakage.

  Note that, for example, the conductors 31 and 32 in FIGS. 4 and 55 adhere to dust or the like due to static electricity due to discharge, which may reduce the amount of discharge. May be removed to remove dust and the like from the conductors 31 and 32. Here, the upper limit of the distance between the protective plates 61 and 62 is not particularly limited as long as the distance between the protective plates 61 and 62 is formed to be at least twice as long as the tip portions 31 and 32 of the discharge electrodes 21 and 22. However, it is desirable that the distance is set so that the user's finger does not touch the conductors 25 and 26. Thereby, it can prevent that a user's finger | toe contacts the conductors 25 and 26. FIG.

  The protection plates 61 and 62 are each formed in a glasses shape. Specifically, the protective plate 61 includes a beam portion 71 made of a horizontal plate parallel to the surface of the ion generating element substrate 14, support portions 72 and 73 that are columns that support both ends of the beam portion 71, and a beam portion. And a support portion 74 that is a support column that supports the central portion of 71.

  Between the adjacent support parts 72 and 74 and between the support parts 74 and 73 are opened. For this reason, the protective plate 61 is provided with two openings 61a and 61b.

  Similarly, the protection plate 62 includes a beam portion 81 made of a horizontal plate parallel to the surface of the ion generating element substrate 14, support portions 82 and 83 that are pillars that support both ends of the beam portion 81, and the beam portion 81. And a support portion 84 that is a support column that supports the center portion.

  Openings are formed between the support portions 82 and 84 adjacent to each other and between the support portions 84 and 83. For this reason, the protective plate 62 is provided with two openings 62a and 62b.

  The support portions 72 and 73 are respectively provided so as to face each other at both ends in the longitudinal direction of the ion generating element substrate 14. Further, the support portion 74 is provided so as to protrude from the center portion of the ion generating element substrate 14 in the longitudinal direction so as to face the support portions 72 and 73.

  Similarly, the support portions 82 and 83 project from the both ends of the ion generating element substrate 14 in the longitudinal direction so as to face each other. Further, the support portion 84 protrudes from the center portion in the longitudinal direction of the ion generating element substrate 14 so as to face the support portions 82 and 83.

  As a result, the beam portions 71 and 81 are bridged from one end in the longitudinal direction of the ion generating element substrate 14 to the other end in parallel with the long side 14 a of the ion generating element substrate 14. Is provided.

  When the discharge electrodes 21 and 22 are viewed through the protective plates 61 and 62 (that is, when the ion generator 2 is viewed from a direction parallel to the side 10a of the case 10), the discharge electrodes 21 and 22 are discharged from the openings 62a and 61b. Is exposed, and the discharge electrode 22 is exposed from the openings 62b and 61a.

  These openings 61 a, 61 b, 62 a, and 62 b function as, for example, a vent for passing a gas that carries ions generated by the discharge electrodes 21 and 22 of the ion generator 2.

  In the example shown in FIGS. 4 and 5, the protection plates 61 and 62 have the tip portions 31 and 32 of the discharge electrodes 21 and 22 (that is, the tip portions of the conductors 25 and 26) and the beam portions 71 and 81. It is formed at a height hidden by

  However, the height of the protective plates 61 and 62 (that is, the height from the surface of the insulating sealing material 41 to the upper surface of the beam portions 71 and 81) is determined from the surface of the insulating sealing material 41 to the conductors 25 and 26. It is sufficient that the height is set higher than the tip 25a / 26a, and the discharge electrode 21 is exposed from the openings 62a / 61b, and the discharge electrode 22 is exposed from the openings 62b / 61a. May be.

  According to the present embodiment, as described above, at least a part of the discharge electrode 21 is exposed from the openings 62a and 61b, and at least a part of the discharge electrode 22 is exposed from the openings 62b and 61a. The release of ions by the discharge electrodes 21 and 22 is not hindered by 61 and 62, and favorable ion release can be performed.

  Further, since the openings 61a, 61b, 62a, and 62b have such a size that the fingers do not contact the conductors 25 and 26, it is possible to prevent the fingers from contacting the conductors 25 and 26. .

  In the present embodiment, the plate-like attachment portions 33a and 34a are attached to the ion generating element substrate 14 such that the normal direction of the plate surface is the left-right direction. As described above, the conductors 25 and 26 are likely to fall in the direction in which the thickness of the sheet-metal mounting portions 33a and 34a is thin, but are difficult to fall in the direction in which the thickness of the sheet-metal mounting portions 33a and 34a is thick. For this reason, the discharge electrodes 21 and 22 are easy to fall down in the left-right direction, but are hard to fall down in the front-rear direction. Therefore, the protective plates 61 and 62 provided in the front-rear direction of the discharge electrodes 21 and 22 do not come close to the conductors 25 and 26 of the discharge electrodes 21 and 22, and leakage can be effectively prevented.

  In other words, the plate-like attachment portions 33a and 34a of the discharge electrodes 21 and 22 are for the ion generating element so that the protective plates 61 and 62 do not exist in the normal direction of the plate surface from the attachment portions 33a and 34a. It is desirable that it is attached to the substrate 14.

  Therefore, as shown in FIGS. 4 and 5, the protective plates 61 and 62 are disposed adjacent to the discharge electrodes 21 and 22 in a direction parallel to the short side 14 b of the ion generating element substrate 14. Thus, the conductors 25 and 26 and the protective plates 61 and 62 are not close to each other, and leakage can be effectively prevented.
