That is, as will be described later, it is sufficient that the external input line can contact the external connection terminal 70 through the lid member 110b.

  The pointed end side of the first discharge electrode 160 is located outside the negative electrode case portion 120. The pointed end side of the second discharge electrode 170 is located outside the positive electrode case portion 130. In the present embodiment, the first discharge electrode 160 and the second discharge electrode 170 face each other with a space therebetween, but the present invention is not limited to this. For example, the first discharge electrode 160 and the second discharge electrode 170 May be arranged in parallel.

  As shown in FIG. 1, in the ion generator, the negative electrode case portion 120 engages with the inner wall on one side of the duct 20. The positive electrode case part 130 engages with the inner wall on the other side opposite to the one side of the duct 20. Accordingly, the first discharge electrode 160 protrudes from the inner wall on one side of the duct 20. The second discharge electrode 170 protrudes from the inner wall of the duct 20 so as to face the first discharge electrode 160 at a distance from the first discharge electrode 160 in a direction orthogonal to the blowing direction.

  The induction electrode 180 is arranged on an intermediate inner wall connecting the inner wall on one side and the inner wall on the other side in the duct 20. As a result, the induction electrode 180 is disposed at a position between the protruding position of the first discharge electrode 160 and the protruding position of the second discharge electrode 170 on the inner wall of the duct 20. The position is shifted from the straight line connecting the tip of the discharge electrode 170.

  In the present embodiment, the induction electrode 180 is disposed at a position where the distance between the first discharge electrode 160 and the induction electrode 180 and the distance between the second discharge electrode 170 and the induction electrode 180 are substantially equal. Has been. However, the position of the induction electrode 180 is not limited to this, and the distance between the first discharge electrode 160 and the induction electrode 180 and the distance between the second discharge electrode 170 and the induction electrode 180 are induced at different positions. An electrode 180 may be disposed.

  In order to efficiently release ions in the ion generator, the ratio of the negative ions generated at the first discharge electrode 160 and the positive ions generated at the second discharge electrode 170 disappear before being discharged from the duct 20. Need to be reduced.

  The causes of the negative ions and positive ions disappearing in the duct 20 are captured by the induction electrode or the discharge electrode having the reverse polarity, trapped on the inner wall of the duct 20, and bound to the reverse polarity ion. .

  In the ion generator including the ion generator according to the present embodiment, the first discharge electrode 160 and the second discharge electrode 170 are arranged on the opposite sides in the duct 20 and separated from each other, so that negative ions and The positive ions are prevented from being captured by the discharge electrode having the reverse polarity.

  Further, in order to suppress negative ions and positive ions from being captured by the induction electrode, the distance between the first discharge electrode 160 and the induction electrode 180 and the distance between the second discharge electrode 170 and the induction electrode 180 are also illustrated. These distances are secured at a predetermined distance or more.

  The first discharge electrode 160 and the induction electrode 180, the second discharge electrode 170 and the induction electrode 180, and the distances between the electrodes in the first discharge electrode 160 and the second discharge electrode 170, which are electrically different in polarity, are By ensuring the predetermined distance or more, it is possible to suppress the occurrence of a leak current that may occur depending on the use environment. In conventional ion generators, for example, when an ion generator is used for a long time in a dusty and humid environment, dust adheres to the case of the ion generator, and leakage current is generated through the creepage of this case. There was something to do. In the ion generating apparatus according to the present embodiment, even if dust adheres to the case of the ion generator due to long-term use by securing the distance between the electrodes of different polarities to a predetermined distance or more, this case Leakage current between the electrodes through the creeping surface is less likely to occur.

  As described above, the induction electrode 180 is provided on the inner wall of the duct 20 so as to be shifted from the straight line connecting the tip of the first discharge electrode 160 and the tip of the second discharge electrode 170, thereby reducing the size. Within the restricted dimensions of the ion generator, the distance between the first discharge electrode 160 and the induction electrode 180 and the distance between the second discharge electrode 170 and the induction electrode 180 are each ensured to a maximum at a predetermined distance or more. can do.

  As described above, in the ion generating apparatus according to the present embodiment, the space inside the duct 20 is effectively used as much as possible, thereby suppressing the generation of leakage current due to long-term use while suppressing a decrease in ion emission efficiency. Thus, the durability can be improved and the enlargement of the duct 20 can be suppressed. In other words, compared to the case where the induction electrode 180 is provided in an internal space that is not the inner wall of the duct 20, the outer shape of the duct 20 can be reduced, and the ion generator can be downsized.

  FIG. 5 is a plan view showing an insulating sealing structure in the ion generator according to the present embodiment. 6 is a view of the insulating sealing structure of FIG. 5 as viewed from the direction of the arrow VI. 5 and 6, the case is shown through.

  As shown in FIGS. 5 and 6, a transformer 50 and a transformer driving circuit including a diode 61, a capacitor 60, and other resistors are mounted on the lower surface of the substrate 10. External connection terminals 70 are mounted on the upper surface of the substrate 10. That is, components other than the first discharge electrode 160 and the second discharge electrode 170 among components to which a high voltage is applied are concentrated on the substrate 10.

  As described above, the substrate 10 is accommodated in the main body case portion 110, the substrate 30 on which the first discharge electrode 160 is mounted is accommodated in the negative electrode case portion 120, and the substrate 40 on which the second discharge electrode 170 is mounted is positive. It is accommodated in the electrode case part 130.

  The container member 110a of the main body case portion 110 stores therein the first insulating sealing portion 90 filled from the upper opening as indicated by an arrow 2 in FIG. The first insulating sealing portion 90 is made of an insulating resin such as an epoxy resin that is an insulating material.

  The main body case portion 110 and the left conductor case portion 140 are partitioned by a partition wall 141. The main body case portion 110 and the right conductor case portion 150 are partitioned by a partition wall 151.

  The partition walls 141 and 151 are formed to a height above the upper surface of the substrate 10 and to ensure a gap in which the connection conductors 80 and 81 can be routed between the partition walls 141 and 151 and the lid member 110b.

  The first insulating sealing portion 90 is filled up to a position above the upper surface of the substrate 10 and below the end surface of the external connection terminal 70 opposite to the substrate 10 side. By doing so, the substrate 10 can be reliably sealed by the first insulating sealing portion 90, and the side opposite to the substrate 10 side of the external connection terminal 70 is outside the first insulating sealing portion 90. Can be positioned.

  As described above, since the lid member 110 b has the hole 111 at a position covering the external connection terminal 70, the external input line is inserted in the direction indicated by the arrow 71, and the first insulating seal is passed through the hole 111. By connecting to the external connection terminal 70 located outside the stopper 90, the external input line and the external connection terminal 70 can be electrically connected.

  The container member 110a of the negative electrode case part 120 and the positive electrode case part 130 stores therein the second insulating sealing part 91 filled from the upper opening as shown by an arrow 2 in FIG. The second insulating sealing portion 91 is made of an insulating resin such as an epoxy resin.

  The negative electrode case part 120 and the left conductor case part 140 are partitioned by a partition wall 142. The positive electrode case part 130 and the right conductor case part 150 are partitioned by a partition wall 152.

  The partition walls 142 and 152 are formed to a height above the upper surfaces of the substrates 30 and 40 and to ensure a clearance that allows the connection conductors 80 and 81 to be routed between the partition walls 142 and 152 and the lid member 110b.

  The second insulating sealing portion 91 is filled up to a position above the upper surfaces of the substrates 30 and 40. By doing in this way, the board | substrates 30 and 40 can be reliably sealed with the 2nd insulation sealing part 91. FIG.

  With the above configuration, one end of each of the connection conductors 80 and 81 is sealed by the first insulating sealing portion 90, and the other end of the connection conductors 80 and 81 is sealed by the second insulating sealing portion 91. Therefore, only the connection part with the board | substrates 10, 30, and 40 of the connection conductors 80 and 81 can be sealed easily.

  In the present embodiment, since the convex portion is provided on the container member 110a only in a portion corresponding to the transformer 50 having a large volume, the case is larger than the case where the entire container member 110a is enlarged to accommodate the transformer 50. Can be reduced. Therefore, the ion generator 100 can be miniaturized.

  In order to further reduce the size of the case, the container member 110a may be formed so that the outer shape thereof conforms to the outer shape of the transformer 50 and the transformer drive circuit provided on the substrate 10 accommodated inside the container member 110a.

  In the ion generator 100 according to the present embodiment, a high voltage concentrated on the substrate 10 is applied by filling the main body case portion 110 with the first insulating sealing portion 90 from above as indicated by the arrow 2. Therefore, the manufacturing time and manufacturing cost of the ion generator 100 can be reduced.
