- the structure is the same as that of the ion generator 1 shown in FIG. 1, but the measurement result of the ion generation amount of the ion generator is also shown with the ground electrode 42 connected to the insulating case. (See dotted line). From the graph, it can be seen that the ion generation voltage is lowered by connecting the Darnd electrode 42 to the insulating case. Also, the voltage that reaches the measurement limit is lower than when the ground electrode 42 is not connected to the insulation case.
- FIG. 9 is a graph showing the amount of ions generated at a point 50 cm away from the ion generator 1 when the input voltage is fixed at ⁇ 2.5 kV (see solid line).
- the structure is the same as that of the ion generator 1 shown in FIG. 1, except that the ground electrode 42 is connected to the insulating case! Describe (see dotted line). It can be seen from the graph that the amount of ions generated increases when the ground electrode 42 is connected to the insulating case.
- the power supply circuit and insulation structure can be simplified.
- the AC voltage generated in the AC circuit 65 is boosted by the transformer 66, and further boosted by the cockcroft circuit (a circuit that rectifies and doubles the voltage by combining the capacitor C and the diode D).
- the voltage is boosted by a transformer 66 at about ⁇ lkV to ⁇ 1.5 kV, and then boosted by a cockcroft circuit 67 as shown in FIG.

- the linear electrode 45 and the ground electrode 42 are planarly formed on the insulating substrate 41, The volume is reduced and the size can be reduced.
- Table 2 shows the results of measuring the amount of ozone generated when the voltage applied to the linear electrode 45 is changed. The measurement point is 5 mm away from the ion generator 1. The wind speed was OmZs. Table 2 also shows, for comparison, the results of measuring the amount of ozone generated using a single saw tooth 112a of the conventional ion generator 110 shown in FIG.
- the ion generation apparatus 1 of this example has an extremely small amount of ozone generation in the use state. Furthermore, since the insulating film 44 covering the ground electrode 42 is formed, the discharge start voltage between the ground electrode 42 and the linear electrode 45 can be increased as compared with the case of air alone. As a result, dark current (leakage current, not discharge) flowing between the tip of the linear electrode 45 and the ground electrode 42 can be suppressed. As a result, the amount of ozone generated in proportion to the amount of current can be reduced.
- the ground electrode 42 is disposed between the ground electrode 42 and the linear electrode 45. It is possible to prevent problems such as abnormal discharge.
- FIG. 11 is a plan view of another ion generating component 4A.
- the ground electrode 42 of the ion generating component 4A has only one leg portion 42a parallel to the linear electrode 45.
- the insulating film 44 covers only the ground electrode 42 and its vicinity, leaving a contact portion 42c that does not cover substantially the entire surface of the insulating substrate 41. Also, this ion generating component 4A is insulated by the contact part 42c. When directly joined to the upper case 3 of the case, there is a characteristic.
