  Hereinafter, an embodiment of the present invention relating to an ozone generator will be described with reference to the drawings. First, in FIG. 1, which is a simplified structural diagram of an ozone generator, when AC power or DC power is supplied from the power supply circuit 1, a high voltage is generated in the high voltage generator 2, and this high voltage is generated by the ozone generator. 3 is supplied to one discharge electrode 3A which is the first embodiment.

  When AC power or DC power is supplied from the power supply circuit 1, the high voltage generator 2 boosts the voltage by a transformer or the like and outputs a high voltage of several thousand volts to the one discharge electrode 3A. The other discharge electrode 3 </ b> B is connected to the ground, and the ground is provided outside the high voltage generator 2, but may be provided inside the high voltage generator 2.

  Both the discharge electrodes 3A and 3B are composed of conductive plates, and the distance between the discharge electrodes 3A and 3B is preferably determined by the voltage value supplied from the high voltage generator 2. That is, the current value of the current flowing between the discharge electrodes 3A and 3B due to discharge varies depending on the height of the voltage supplied from the high voltage generator 2 and the distance between the discharge electrodes 3A and 3B. In this case, ozone and ions are generated by this discharge when the current value is large, and only ions are generated by this discharge when the current value is small.

  The pair of discharge electrodes 3A and 3B may be installed in parallel, but by adjusting the angle so that they are not parallel to each other, the intensity of the discharge can be adjusted and adjusted from voiced discharge to silent discharge. Can do.

  Next, a second embodiment of the ozone generating unit 3 will be described with reference to FIG. 2, but since the pair of discharge electrodes have the same structure, one discharge electrode 3C will be described. A plurality of conductive wires 4 are fixed to a fixed portion 5 having conductivity formed of conductive synthetic resin or metal by pressure bonding. And when the wire 4 is comprised with a metal, it fixes to the fixing | fixed part 5 after taking an oxidation countermeasure etc. When a high voltage is supplied from the high voltage generator 2 to the one discharge electrode 3 </ b> C, the high voltage generator 2 is configured to supply the fixed portion 5.

  In addition, although the number and length of the wire 4 may be changed as necessary, each wire 4 is fixed to the fixing portion 5 with an equal interval parallel to a certain direction. The conductive fixing part 5 of the one discharge electrode 3C is connected to the high-voltage generator 2 and the conductive fixing part 5 of the other discharge electrode 3C is connected to the ground.

  Next, a third embodiment of the ozone generating unit 3 will be described with reference to FIG. 3, but since the pair of discharge electrodes have the same structure, one discharge electrode 3D will be described. The discharge electrode 3D is formed by fixing, for example, a metallic net 6 having conductivity to the fixing portion 7 having conductivity by pressure bonding. The conductive fixing portion 7 of the one discharge electrode 3D is connected to the high-voltage generator 2 and the conductive fixing portion 7 of the other discharge electrode 3D is connected to the ground.

  And this net | network 6 exhibits various shapes, as shown to FIG. 3 (A), (B), (C), (D), (E). That is, as shown in FIG. 3 (A), the outer shape constituted by a plurality of wires extending in the vertical direction and the horizontal direction may be rectangular, and as shown in FIGS. 3 (B) and 3 (C), The outer shape composed of a plurality of wires extending diagonally right upward and diagonally downward to the right may be rectangular, and as shown in FIG. 3D, a plurality of wires extending in the vertical and horizontal directions. The outer shape configured in (3) may be triangular, and as shown in FIG. 3 (E), the outer shape configured by a plurality of wires extending in the vertical and horizontal directions may be arc-shaped.

  And as shown in FIGS. 3 (A), (C), (E), the outer peripheral edge may be cut at a place other than the seam of the mesh, and as shown in FIGS. 3 (B), (D), What cut | disconnected the outer periphery part in the location of the joint of a net | network may be used. In this case, cutting at a portion other than the joint increases the number of discharge points at the tip of the discharge electrode 3C, and ozone and ions, or only ions are easily generated.

  And FIG. 4 which is the graph which measured the generation amount of ozone by the location which the said net | network 6 cut | disconnected 3D of discharge electrode 3D is demonstrated. The graph of FIG. 4 is a graph in which the vertical axis represents the ozone concentration and the horizontal axis represents the passage of time. A line graph group in which the ozone concentration is stable around 6 ppm (part per million) is a net 6 cut at a portion other than a joint, and an unstable line graph group is a net 6 cut at a seam.

  Comparing the discharge electrode 3D of FIG. 3B with the discharge electrode 3D of FIG. 3C, the number of discharge tips of the mesh 6 is approximately twice that of the discharge electrode 3D of FIG. 3C. As the number of discharge tips increases, the ozone concentration becomes more stable. Therefore, in order to increase the discharge tip, the size of the conductive mesh 6 may be increased, or a fine mesh may be used. Further, the net 6 may be cut out to increase the number of discharge tips.

  Next, a fourth embodiment of the ozone generating unit 3 will be described with reference to FIG. 5, but since one pair of discharge electrodes has the same structure, one discharge electrode 3E will be described. The discharge electrode 3E has conductivity, for example, one or a plurality of metallic plates, a plurality of metallic wires, a net formed of the metallic wires (hereinafter referred to as “plate”). The body etc. 8 "is fixed to the fixing portion 9 having conductivity, and the plate body 8 is bent and fixed so as not to be perpendicular to the mounting surface of the fixing portion 9.

  Specifically, as shown in FIGS. 5 (F) and 5 (G), only the tip portion of the plate body 8 or the like may be bent, or as shown in FIG. 5 (H), from the root portion, that is, from the fixing portion 9. It may be bent or may be bent from the middle as shown in FIG. Further, the bending method may be provided with an angle as shown in FIGS. 5F and 5G or an arc shape.

  Then, a pair of discharge electrodes 3E configured as described above is prepared, and the fixing portion 9 having the conductivity of one discharge electrode 3E is connected to the high-voltage generator 2 and the conductivity of the other discharge electrode 3E is set. The fixed portion 5 is connected to the ground, and the paired electrodes 8 such as the plate bodies 8 are arranged side by side so that the tip portion is closer to the portion other than the tip portion.

  Next, a fifth embodiment of the ozone generating unit 3 will be described with reference to FIG. 6, but this embodiment has a structure in which a pair of discharge electrodes 3F are integrated, and will be described below. The discharge electrode 3F has conductivity, for example, one or a plurality of metallic plates, a plurality of metallic wires, a net formed of the metallic wires (hereinafter referred to as “plate”). The body etc. 10 ”) is fixed to the fixing portion 11.

  The fixing portion 11 includes a first fixing portion 11A having conductivity for fixing one plate body 10 and the like, a second fixing portion 11B having conductivity for fixing the other plate body 10 and the like, The non-conductive connecting portion 11C that connects the first fixing portion 11A and the second fixing portion 11B. Then, one fixing part 11A or 11B is connected to the high-pressure generator 2, and the other fixing part 11B or 11A is connected to the ground.

  Then, ozone can be generated or ions can be generated by adjusting the discharge area and the angle with respect to the mounting surface of the fixing portion 11. For example, a pair of plate bodies 10 or the like may be provided in parallel as shown in FIGS. 6 (J) and (M), or only the tip portion of one plate body 10 or the like as shown in FIG. 6 (K). As shown in FIG. 6 (L), only the tip portions of the pair of plate bodies 10 or the like are bent inward (may be linear or curved), or as shown in FIG. 6 (N). An angle is set so that the front end sides of the plate bodies 10 are close to each other, or as shown in FIG. 6 (O), they are bent from the middle of the pair of plate bodies 10 and bent so that the front end portions are close. Like (P), you may bend in a circular arc shape inside so that only the front-end | tip parts of a pair of board etc. 10 may become near.

  In addition, when the pair of plate bodies 10 or the like is constituted by a plate body or a net, the distance between the tips (upper ends) of the pair of plate bodies 10 is not limited even if the tip portion is bent or not. Plates and nets are arranged at the same interval over the entire length. Thereby, the generation of ozone is stabilized.

  In this case, one or both of the plate bodies 10 or the like are bent so that the distance between the pair of electrodes such as the plate bodies 10 is close to the tip portion only, that is, the tip portion is closer to the portion other than the tip portion. In such a case, ozone may be generated at the near tip, and ions may be generated at other locations (distant portions).

  FIG. 7 and FIG. 8 that are graphs showing the amount of ozone generated by the ozone generator 3 according to the fifth embodiment will be described. The graph of FIG. 7 shows a line graph when the discharge electrode 3F having the structure of FIG. 6 (J) is used, and the graph of FIG. 8 is a line graph when the discharge electrode 3F having the structure of FIG. 6 (L) is used.

  As shown in FIG. 7, when the discharge electrode 3F having the structure of FIG. 6 (J) is used, the ozone concentration varies greatly, and as shown in FIG. 8, the discharge electrode having the structure of FIG. 6 (L). When 3F is used, it is stable with little variation in ozone concentration. This is a result of the ozone generation amount being stabilized without causing unnecessary discharge by setting the discharge location as a specific location.

  Next, a sixth embodiment of the ozone generator 3 will be described with reference to FIG. 9, but since the pair of discharge electrodes have the same structure, one discharge electrode 3G will be described. The discharge electrode 3G has a structure in which the mesh 12 made of, for example, a metal wire material is fixed to the fixing portion 14, and will be described in detail below.

You may integrate by the insert molding which shape | molds by the injection molding of a nonelectroconductive synthetic resin, and makes it an integral product. In addition, when using a several plate body, these plate bodies are made to contact directly or connect with the connection body which has electroconductivity, and insert molding is performed.
