The filler is an insulating resin.

[0003] However, in a certain discharge device, under harsh conditions such as high humidity and condensation, water droplets sometimes adhere to the support parts, such as the discharge electrode needles, on the filler, and moisture seeps between the support parts and the filler. Because of the water droplets adhering to the support parts, the discharge electrode needles may corrode. Summary of the Invention

[0016] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, the same or equivalent parts in the drawings will be labeled with the same reference numerals, and their descriptions will not be repeated. In the embodiments of the present invention, the X-axis, Y-axis, and Z-axis are orthogonal to each other, the X-axis and Y-axis are parallel to the horizontal plane, and the Z-axis is parallel to the vertical line.

[0017] Reference Figure 1 Figure 4 The discharge device 100 according to the first embodiment of the present invention will be described below. First, referring to... Figure 1 This describes the discharge device 100 of the first embodiment. Figure 1 This diagram illustrates the discharge device 100 according to the first embodiment. The discharge device 100 generates active groups by discharging. The active groups contain ions.

[0018] The discharge device 100 has a plurality of electrodes 19, a housing portion 1, and a cover portion 2. The plurality of electrodes 19 are discharged by applying a voltage. The plurality of electrodes 19 may be, for example, two electrodes 19. That is, the plurality of electrodes 19 may be, for example, a pair of electrodes 19. A portion of each of the pair of electrodes 19 penetrates the cover portion 2.

[0019] The housing 1 houses a portion of a pair of electrodes 19. The housing 1 is a box-shaped housing. The housing 1 is insulating. The housing 1 is, for example, formed of resin.

[0020] The cover portion 2 covers the portion of the receiving portion 1 in which a pair of electrodes 19 are disposed. The cover portion 2 is insulating. The cover portion 2 is, for example, formed of resin.

[0021] Next, refer to Figure 2 Detailed description of the discharge device 100. Figure 2 It means Figure 1 A cross-sectional view (II-II) of the discharge device 100 shown. Figure 2As shown, the discharge device 100 also includes multiple sensing electrodes 132, a first substrate 51, a second substrate 52, a third substrate 53, electronic components 7, a transformer 8, and insulating components 9.

[0022] like Figure 2 As shown, the housing 1 houses a first substrate 51, a second substrate 52, a third substrate 53, an electronic component 7, a transformer 8, and an insulating component 9. The housing 1 is box-shaped with an opening 13. The housing 1 has a side wall portion 11 and a bottom wall portion 12.

[0023] The bottom wall portion 12 supports the side wall portion 11. A transformer 8 and electronic components 7 are disposed on the bottom wall portion 12. The side wall portion 11 surrounds the bottom wall portion 12. The side wall portion 11 extends from the bottom wall portion 12 toward the opening 13.

[0024] A plurality of sensing electrodes 132 form an electric field between the sensing electrode 132 and the electrode 19. The plurality of sensing electrodes 132 may be, for example, two sensing electrodes 132. That is, the plurality of sensing electrodes 132 may be, for example, a pair of sensing electrodes 132. The pair of sensing electrodes 132 are respectively disposed around the electrode 19. The sensing electrodes 132 are annular or substantially annular. Substantially annular means that a portion of the sensing electrode 132 is interrupted in the circumferential direction.

[0025] A pair of sensing electrodes 132 are connected to the first substrate 51.

[0026] The pair of electrodes 19 are, for example, brush-shaped electrodes. The pair of electrodes 19 are connected to the second substrate 52. The pair of electrodes 19, when subjected to a high voltage, generate corona discharge. That is, the pair of electrodes 19 discharge to generate ions.

[0027] For example, one of a pair of electrodes 19 releases positive ions through discharge. Positive ions are formed when hydrogen ions (H+) are present in the atmosphere. + Cluster ions (H+) formed by the clustering of multiple water molecules around a group of water molecules. + (H2O) m (m is any positive number above zero). Furthermore, for example, one electrode 19 of a pair of electrodes 19 releases negative ions through discharge. Negative ions are oxygen ions (O... 2- Cluster ions (O) formed by the clustering of multiple water molecules around ) 2- (H2O) n (n is any positive number above zero).

[0028] When both positive and negative ions are emitted, the greater the interval between the electrode 19 that emits positive ions and the electrode 19 that emits negative ions, the greater the amount of ions emitted from each electrode 19.

[0029] The released positive and negative ions, for example, surround airborne mold, initiating a chemical reaction on the mold's surface. This chemical reaction generates reactive hydroxyl radicals (·OH). Furthermore, the mold is removed through the action of these hydroxyl radicals (·OH).

[0030] A pair of sensing electrodes 132 are disposed on a first substrate 51. The first substrate 51 is electrically connected to the pair of sensing electrodes 132. The first substrate 51 is a so-called printed circuit board. The first substrate 51 is disposed at a position closer to the opening 13 than the second substrate 52. The first substrate 51 is connected to a transformer 8 via leads. The first substrate 51 is connected to a third substrate 53 via the transformer 8.

[0031] A pair of electrodes 19 are disposed on the second substrate 52. The second substrate 52 is electrically connected to the pair of electrodes 19. The second substrate 52 is a so-called printed circuit board. The second substrate 52 is disposed on the side closer to the opening 13 than the third substrate 53. The second substrate 52 is connected to the transformer 8 via leads. The second substrate 52 is connected to the third substrate 53 via the transformer 8.

[0032] A circuit is formed on the third substrate 53. Specifically, a circuit for electrical connection with the first substrate 51, the second substrate 52, the transformer 8, and the electronic component 7 is formed on the third substrate 53. More specifically, the third substrate 53 electrically connects the transformer 8 and the electronic component 7 through a pattern. Specifically, the third substrate 53 is connected to the terminals of the transformer 8. The third substrate 53 is disposed between the electronic component 7 and the second substrate 52.

[0033] Electronic components 7 include, for example, power terminals, diodes, resistors, transistors, capacitors, etc. The power terminals are connected to an external power source via a pattern.

[0034] Transformer 8 boosts the voltage generated in electronic component 7 and applies the resulting high voltage to a pair of electrodes 19.

[0035] The insulating component 9 is insulating. The insulating component 9 is, for example, polyurethane resin or epoxy resin. The insulating component 9 cures, for example, over time. Alternatively, the insulating component 9 may be cured by temperature (heat) or light (ultraviolet light).

[0036] The cover 2 covers the opening 13 of the receiving part 1. The cover 2 includes a main body 21 and a pair of openings 20. A pair of electrodes 19 are respectively inserted through the pair of openings 20.

[0037] Next, refer to Figure 3 and Figure 4 The discharge device 100 will be described in more detail. Figure 3 It is shown in magnification Figure 2 A diagram of electrode 19 is shown. For ease of understanding of the invention, in... Figure 3 and Figure 4 The image shows electrode 19, second substrate 52, and insulating component 9. Figure 4 Observing from other angles Figure 3 Figure 19 of electrode 19.

[0038] like Figure 3 and Figure 4 As shown, electrode 19 includes a support portion 191 and a discharge component 192.

[0039] The support portion 191 supports the discharge component 192. Voltage is applied to the support portion 191 together with the discharge component 192. The support portion 191 has a main body portion 194. The main body portion 194 penetrates the second substrate 52. Furthermore, the main body portion 194 penetrates the insulating component 9.

[0040] like Figure 4 As shown, the main body 194 has a flat plate shape. The main body 194 has a pair of opposing first surfaces 191A, a pair of opposing second surfaces 191B, a first support end 191C, and a second support end 191D. The pair of second surfaces 191B are disposed between one first surface 191A and the other first surface 191A. The width of the first surface 191A is greater than the width of the second surface 191B. That is, the area of ​​the first surface 191A is greater than the area of ​​the second surface 191B. In other words, the main body 194 is a thin plate.

[0041] The first support end 191C is the end on the side of the first direction D1. The first direction D1 indicates the direction from the second substrate 52 toward the discharge member 192. The first support end 191C passes through the insulating member 9 and protrudes to the outside of the insulating member 9. The first support end 191C corresponds to the portion CA that protrudes to the outside of the insulating member 9.

[0042] The second support end 191D is the end on the second direction D2 side. The second support end 191D is connected to the second substrate 52. The second direction D2 indicates the direction from the discharge member 192 toward the second substrate 52. A portion of the second support end 191D penetrates through the second substrate 52. Another portion of the second support end 191D is located inside the insulating member 9. The other portion of the second support end 191D corresponds to the portion CB located inside the insulating member 9.

[0043] The discharge component 192 is discharged when a voltage is applied.

[0044] Additionally, the discharge device 100 also includes a covering member 201. The covering member 201 covers the support portion 191. The covering member 201 is a resin that shrinks upon heating. The covering member 201 has a cylindrical shape. The covering member 201 is, for example, a heat-shrinkable tube. Before shrinkage, the covering member 201 is a cylindrical shape larger than the support portion 191. After shrinkage, the covering member 201 is formed into a cylindrical shape smaller than the support portion 191. Therefore, the shrinkage covering member 201 can cover the support portion 191.

[0045] Specifically, the covering member 201, before shrinkage, is inserted through the support portion 191. Then, the covering member 201 is heated. Then, the covering member 201 shrinks until it is tightly attached to the surfaces of a pair of first surfaces 191A and a pair of second surfaces 191B. That is, the covering member 201 covers the support portion 191 while reducing the gap between the covering member 201 and the support portion 191.

[0046] The covering member 201 covers the support portion 191, thereby reducing the bending of the support portion 191 due to external forces. For example, the covering member 201 reduces the bending of the support portion 191 due to external forces. Figure 3 The bending in the third direction D3 is shown. The third direction D3 represents the direction along which one first surface 191A moves towards another first surface 191A. For example... Figure 3 As shown, the thickness of the support portion 191 on the third direction D3 is greater than that of the support portion 191. Figure 4 The support portion 191 in the fourth direction D4 is thin. The fourth direction D4 refers to the direction along which one second surface 191B moves towards another second surface 191B. The fourth direction D4 intersects with the third direction D3. That is, the support portion 191 is easy to bend along the third direction D3, but difficult to bend along the fourth direction D4. Therefore, the covering member 201 can reduce the bending of the support portion 191 towards the third direction D3. In addition, an insulating member 9 is filled around the covering member 201.

[0047] Specifically, such as Figure 3 and Figure 4 As shown, the covering member 201 covers the portion CA protruding outward from the insulating member 9 in the support portion 191 and the portion CB located inside the insulating member 9. That is, it can prevent moisture from penetrating between the covering member 201 and the support portion 191. Therefore, it can prevent water droplets from adhering to the support portion 191. As a result, it can suppress corrosion of the support portion 191.

[0048] Next, refer to Figure 3 and Figure 4 Electrode 19 will be described in further detail. For example... Figure 3 and Figure 4As shown, the discharge component 192 is a plurality of fibers. That is, the discharge component 192 is a fiber bundle. Each of the plurality of fibers is a conductor. The discharge component 192 is, for example, carbon fiber. The discharge component 192 can also be, for example, a metal, conductive fiber, or conductive resin. During discharge, a portion of the plurality of fibers in the discharge component 192 disperses.

[0049] The support portion 191 of electrode 19 also has a holding portion 193. The holding portion 193 holds the discharge member 192. The holding portion 193 extends from the support portion 191. The holding portion 193 is made of the same material as the support portion 191 and is integrally formed with the support portion 191. Furthermore, the holding portion 193 bundles multiple fibers of the discharge member 192. That is, the holding portion 193 holds the discharge member 192 in a brush-like manner.

[0050] The retaining portion 193 has a first retaining piece 193A and a second retaining piece 193B. The first retaining piece 193A and the second retaining piece 193B retain the base end of the discharge member 192. Specifically, the first retaining piece 193A and the second retaining piece 193B retain the base end of the discharge member 192 by riveting deformation. By making the first retaining piece 193A and the second retaining piece 193B retain the base end of the discharge member 192, the discharge member 192 becomes brush-shaped.

[0051] In addition, such as Figure 3 and Figure 4 As shown, the first covered end 201A of the covering member 201 represents the end of the covering member 201 that protrudes from the surface 9S of the insulating member 9 toward the discharge member 192. Specifically, the first covered end 201A of the covering member 201 is positioned closer to the insulating member 9 than the discharge member 192, and positioned closer to the discharge member 192 than the surface 9S of the insulating member 9. The first covered end 201A is another part of the covering member 201 that protrudes from the insulating member 9. The first covered end 201A is an example of a "first end". Moreover, the second covered end 201B of the covering member 201 represents the end of the covering member 201 that abuts against the second substrate 52. The second covered end 201B is a part of the covering member 201 disposed inside the insulating member 9. That is, the covering member 201 covers the support portion 191 between the second substrate 52 and the discharge member 192. The second covered end 201B is an example of a "second end". Therefore, the support portion 191 can be covered between the second substrate 52 and the discharge member 192. As a result, the exposed portion of the support portion 191 can be reduced, and water intrusion between the covering member 201 and the support portion 191 can be further suppressed.

[0052] Furthermore, the first covered end 201A of the covering member 201 is positioned closer to the insulating member 9 than the holding portion 193. There is a possibility that the closer the covering member 201 is to the discharge member 192, the weaker the discharge of the discharge member 192 becomes. Therefore, the first covered end 201A of the covering member 201 does not cover the holding portion 193. As a result, it is possible to suppress the weakening of the discharge member 192 by the covering member 201.

[0053] (Variation Example 1)

[0054] Next, refer to Figure 5 This section describes a first modification of the discharge device 100 according to the first embodiment. The main difference between this first modification and the first embodiment lies in the covering member 201 covering and holding portion 193. Hereinafter, the differences between this first modification and the present embodiment will be explained.

[0055] Figure 5 This is an enlarged view showing the electrode 19 of the discharge device 100 involved in the first modified example. For ease of understanding of the invention, in Figure 5 The image shows electrode 19, second substrate 52, and insulating component 9. (See image for details.) Figure 5 As shown, the retaining part 193 has a first retaining end 193C and a second retaining end 193D.

[0056] The first holding end 193C is the end on one side of the discharge component 192. That is, the first holding end 193C is the end on the side in the first direction D1.

[0057] The second retaining end 193D is the end on the insulating member 9 side. That is, the second retaining end 193D is the end on the second direction D2 side. The second retaining end 193D is continuous with the main body 194 of the support portion 191.

[0058] like Figure 5 As shown, in the first modified example, the covering member 201 covers the portion of the support portion 191 from the second substrate 52 to the discharge member 192. Specifically, the first covering end 201A of the covering member 201 is positioned at the first holding end 193C. Furthermore, the second covering end 201B of the covering member 201 abuts against the second substrate 52. Therefore, the entire support portion 191 is covered by the covering member 201. As a result, the exposed portion of the support portion 191 can be reduced, further suppressing moisture adhesion to the support portion 191.

[0059] (Second variation)

[0060] Next, refer to Figure 6This section describes a second modification of the discharge device 100 according to the first embodiment. The main difference between the second modification and the first embodiment lies in the presence of a filling member 202 and a cover portion 203. The differences between the second modification and this embodiment will be explained below.

[0061] Figure 6 This is an enlarged view showing the electrode 19 of the discharge device 100 involved in the second modification. For ease of understanding of the invention, in Figure 6 The image shows electrode 19, second substrate 52, and insulating component 9.

[0062] In addition, such as Figure 6 As shown, the discharge device 100 of this embodiment also includes a cover 203 and a filling member 202.

[0063] The cover portion 203 covers the first covered end portion 201A of the covering member 201. Therefore, the first covered end portion 201A of the covering member 201 is closed by the cover portion 203. As a result, it is possible to further inhibit moisture from entering the interior of the covering member 201 from the first covered end portion 201A.

[0064] Alternatively, the cover portion 203 may not cover the outer edge of the first covered end portion 201A. The cover portion 203 covers at least the boundary portion between the support portion 191 and the first covered end portion 201A. By covering at least the boundary portion between the support portion 191 and the first covered end portion 201A, moisture intrusion into the interior of the covered member 201 can be prevented.

[0065] The cap 203 is made of resin and is thermoplastic. That is, the shape of the cap 203 changes upon heating. Therefore, by heating the cap 203, which is positioned at the first covering end 201A of the covering member 201, the cap 203 penetrates the gap between the covering member 201 and the support portion 191. Thus, the cap 203 reduces the gap between the covering member 201 and the support portion 191. As a result, it is possible to further suppress moisture penetration into the gap between the covering member 201 and the support portion 191.

[0066] A filling component 202 is disposed between the covering component 201 and the support portion 191. The filling component 202 fills the gap between the covering component 201 and the support portion 191. Therefore, the gap between the covering component 201 and the support portion 191 is reduced. As a result, it is possible to prevent moisture from entering the gap between the covering component 201 and the support portion 191, and to prevent the covering component 201 from falling off the support portion 191.

[0067] The filler component 202 is an adhesive. The filler component 202 is applied to the inner surface of the covering component 201. The filler component 202 is a resin and is thermoplastic. That is, the form of the filler component 202 changes with temperature. Specifically, the filler component 202 becomes liquid by heating. Furthermore, the filler component 202 becomes solid by cooling. Additionally, as... Figure 6 As shown, three types of resin are disposed on the outer side of the support portion 191. Specifically, a filling member 202, a covering member 201, and an insulating member 9 are disposed sequentially on the outer side of the support portion 191.

[0068] The melting point of the filling component 202 is lower than that of the covering component 201. Specifically, the filling component 202 melts at the temperature at which the covering component 201 contracts. That is, by heating the covering component 201, the filling component 202 melts and penetrates the gap between the covering component 201 and the support portion 191. Then, the filling component 202 cools and becomes solid, bonding the covering component 201 to the support portion 191. Therefore, it is possible to reduce the gap between the covering component 201 and the support portion 191 while heating the covering component 201, and to bond the covering component 201 to the support portion 191. As a result, the hassle of bonding the covering component 201 to the support portion 191 can be suppressed.

[0069] (Third variation)

[0070] Next, refer to Figure 7 and Figure 8 This section describes a third modification of the discharge device 100 according to the first embodiment. The main difference between the third modification and the first embodiment lies in the shape of the discharge member 192. The differences between the third modification and the first embodiment will be explained below.

[0071] Figure 7 This is an enlarged view of the electrode 19 of the discharge device 100 according to the third modification. For ease of understanding of the invention, in Figure 8 The image shows electrode 19, second substrate 52, and insulating component 9. Figure 8 Observing from other angles Figure 7 Figure 19 of electrode 19.

[0072] like Figure 8 As shown, the discharge component 192 is a flat plate with a pointed front end. In other words, the discharge component 192 is a thin plate with a triangular shape. The discharge component 192 is a conductor. The discharge component 192 extends from the support portion 191. The discharge component 192 and the support portion 191 are made of the same material and are integrally formed with the support portion 191.

[0073] In addition, such as Figure 7 and Figure 8As shown, the first covering end 201A of the covering member 201 is positioned closer to the side of the insulating member 9 than the discharge member 192, and closer to the side of the discharge member 192 than the surface 9S of the insulating member 9. Furthermore, the second covering end 201B of the covering member 201 abuts against the second substrate 52. That is, the covering member 201 covers the support portion 191 between the second substrate 52 and the discharge member 192. Therefore, the support portion 191 can be covered between the second substrate 52 and the discharge member 192. As a result, the exposed portion of the support portion 191 can be reduced, and water intrusion between the covering member 201 and the support portion 191 can be further suppressed.

[0074] More specifically, in the third variation, the first covered end 201A of the covering member 201 is disposed adjacent to the boundary portion of the support portion 191 and the discharge member 192. Furthermore, the second covered end 201B of the covering member 201 abuts against the second substrate 52. Therefore, the entire support portion 191 is covered by the covering member 201. As a result, the exposed portion of the support portion 191 can be reduced, further suppressing moisture adhesion to the support portion 191.

[0075] (Fourth variation)

[0076] Next, refer to Figure 9 This section describes a fourth modification of the discharge device 100 according to the first embodiment. The main difference in this fourth modification is the shape of the electrode 19 compared to the first embodiment. The differences between this fourth modification and the first embodiment will be explained below.

[0077] Figure 9 This is an enlarged view showing the electrode 19 of the discharge device 100 according to the fourth modified example. For ease of understanding of the invention, in Figure 9 The image shows electrode 19, second substrate 52, and insulating component 9.

[0078] like Figure 9 As shown, the support portion 191 is cylindrical. The main body portion 194 of the support portion 191 has a first support end 191C and a second support end 191D.

[0079] The first support end 191C is the end on the side of the first direction D1. The first support end 191C penetrates the insulating member 9 and protrudes to the outside of the insulating member 9. The second support end 191D is the end on the side of the second direction D2. The second support end 191D is connected to the second substrate 52. A portion of the second support end 191D penetrates the second substrate 52. Another portion of the second support end 191D is located inside the insulating member 9.

[0080] The discharge component 192 is needle-shaped with a pointed tip. The discharge component 192 is a conductor. The discharge component 192 extends from the support portion 191. The discharge component 192 and the support portion 191 are made of the same material and are integrally formed with the support portion 191.

[0081] In addition, such as Figure 9 As shown, the first covering end 201A of the covering member 201 is positioned closer to the insulating member 9 than the discharge member 192, and positioned closer to the discharge member 192 than the surface 9S of the insulating member 9. Furthermore, the second covering end 201B of the covering member 201 abuts against the second substrate 52. That is, the covering member 201 covers the support portion 191 between the second substrate 52 and the discharge member 192. Therefore, the support portion 191 can be covered between the second substrate 52 and the discharge member 192. As a result, the exposed portion of the support portion 191 can be reduced, and water intrusion between the covering member 201 and the support portion 191 can be further suppressed.

[0082] More specifically, in the fourth modification, the first covered end 201A of the covering member 201 is disposed adjacent to the boundary portion of the support portion 191 and the discharge member 192. Furthermore, the second covered end 201B of the covering member 201 abuts against the second substrate 52. Therefore, the entire support portion 191 is covered by the covering member 201. As a result, the exposed portion of the support portion 191 can be reduced, further suppressing moisture adhesion to the support portion 191.
