For example, in a 40 L sealed container, the ozone concentration can be increased to about 30 ppb. Ozone of about 30 ppb is at a level where the odor is slightly felt and is a concentration that is very easy to use. As shown in FIG. 13, when a current of 30 ⁇ A or less flows, the ozone generation amount is about 400 ⁇ g / h.

- the protruding length 106 of the needle tip of the discharge electrode 102 becomes positive with respect to zero, that is, when protruding to a position higher than the counter electrode 101 in the drawing, the amount of negative ions increases and the current value decreases remarkably. .
- the protrusion length 106 is preferably larger than zero. As will be described in detail later, as shown in FIGS. 16 and 17, the protrusion length 106 has a current flowing between the counter electrode 101 and the discharge electrode 102 of 5 ⁇ A even at 13 mm, and is sufficiently ozone. The amount generated can be secured. That is, the amount of ozone generated together with the ions can be secured, and ions and ozone can be made compatible at a practical level.

On the other hand, if it is larger than 5 mm, the generated negative ions are captured by the counter electrode 101, so that the amount of negative ions released is reduced. This tendency decreases as the needle tip protrusion length increases.
- the closest distance 107 represents the distance between the tip of the discharge electrode 102 and the counter electrode 101. If the closest distance 107 is reduced, the intensity of discharge increases and the current value between the electrodes increases, and if it is increased, the current value between the electrodes decreases.

- the conductive wire 103 on the discharge electrode side has a pressure-resistant conductive wire such as a fluororesin coating or a silicone resin coating that can withstand a high voltage. desirable.
- FIG. 19 is a schematic cross-sectional view of an indoor unit of an air conditioner according to the third embodiment.
- the indoor unit 210 is mainly composed of a suction port 2, a blower outlet 3, a blower fan 5, a heat exchanger 6, a suction port side air passage 211, a blower outlet side air passage 212, and an ozone / ion generator 108.
- the suction port 2, the air outlet 3, the air inlet side air passage 211, and the air outlet side air passage 212 are formed in the main body 1.
- the dust collection operation function is that when the blower fan 5 rotates, air is taken from the indoor space into the air inlet side air passage 211 via the air inlet 2 and is cooled by the heat exchanger 6 during the cooling operation, It is warmed during heating operation.
- the ozone / ion generator 108 is energized to generate ions from the ozone / ion generator 108, and the ions are supplied from the outlet 3 to the indoor space.
- the dust collection operation function is strongly desired, the operation of increasing the rotational speed of the blower fan 5 is effective from the viewpoint of increasing the amount of released ions and increasing the amount of indoor air taken into the indoor unit 210. Is.
- this dust collecting operation function can also perform a dust collecting operation only by air blowing by the blower fan 5 without operating the heat exchanger 6.
- the operation is performed by operating the ozone / ion generator 108.
- the ozone generated from the ozone / ion generator 108 passes from the ozone / ion generator 108 through the air outlet side air passage 212 to the suction port 2 side.
- Ozone diffuses into the interior of the indoor unit 210 due to the blowing of ion wind. That is, it can be diffused without operating the blower fan 5, and the internal clean operation can be performed without fan driving noise.
- the ozone / ion generator 108 is arranged in the lower part of the air outlet side air passage 212, but the top surface portion of the air outlet side air passage 212 and the side surface portion of the air outlet side air passage 212 are arranged. It is also possible to arrange them.
- the discharge electrode 102 is disposed on the axis of the counter electrode 101 as described with reference to FIG. 8 in the description of the second embodiment. Since the needle tip 102 is arranged at a position where it protrudes from the end face of the counter electrode 101 (projects upward in the drawing), the amount of ions released can be increased even in a no-wind state, and the air volume and wind speed are greatly increased. This is preferable because ions can be stably discharged into the indoor space without being influenced.
- This ion wind radiates strongly from the discharge electrode 102 toward the counter electrode 101. Further, when the arc angle of the counter electrode 101 is increased, the spread of the ion wind is increased. Conversely, when the arc angle of the counter electrode 101 is decreased, the spread of the ion wind is decreased. In the case where the counter electrode 101 is disposed above the discharge electrode 102, the ion wind is directed upward toward the counter electrode 101. Therefore, it is preferable to incline the needle tip of the discharge electrode 102 toward the blower fan 5 in order to generate ion wind toward the suction port 2 side.
- the high voltage generator 104 applies a high voltage between the counter electrode 101 and the discharge electrode 102, but is a positive or negative DC voltage. Applying a negative DC voltage is more preferable than applying a positive DC voltage, and ozone is more likely to be generated, and a negative DC voltage is more desirable because it is easier to control the amount of ions released into the room and the amount of ozone generated. Moreover, although a pulse and alternating current can also be used, it is preferable in that the ion wind can be continuously generated by using direct current.
- FIG. 20A and 20B show the ozone / ion generator 108 incorporated in the air conditioner according to Embodiment 3 of the present invention
- FIG. 20A is a plan view seen from above the ozone / ion generator

- the arc center direction 232 has an inclination of an angle 233 with the upwind direction of the arc center with respect to the upwind direction 231.
- the windward direction 231 and the arc center direction 232 are substantially the same.
- ion wind is generated from the axis of the needle electrode toward the counter electrode, so that ozone spreads from the center to the inside of the indoor unit, and the ozone is spread inside the indoor unit. It is suitable for making it.

- the angle is set to 90 degrees, most of the counter electrode 101 can exist on the windward side of the discharge electrode 102 during the operation of the dust collecting operation function. Thereby, it is suppressed that ions generated by the wind from the blower fan are neutralized by the counter electrode, and a large amount of ions are released into the indoor space, which is preferable.
- ion wind is generated from the axis of the needle electrode toward the counter electrode, so that ozone spreads from the end to the interior of the indoor unit, and ozone enters the interior of the indoor unit. It is suitable for spreading.
- the ozone / ion generator 108 is installed at the right end as viewed from the front, but can also be installed at the left end.
- the arc center direction 232 is the windward direction 231. Is symmetric about the axis.
- one ozone / ion generator 108 is installed at one end of each side, but one ozone / ion generator 108 can be installed at each end of each side. Accordingly, the angle 233 with the upwind direction at the center of the arc becomes smaller.
- the ion wind radiates strongly from the discharge electrode 102 toward the counter electrode 101. If the arc angle 234 of the counter electrode 101 increases, the spread of the ion wind increases and disperses. Conversely, if the arc angle 234 of the counter electrode 101 decreases, the spread of the ion wind decreases and the local concentration is concentrated. Resulting in. Therefore, the arc angle 234 is preferably 90 degrees to 270 degrees.
- the counter electrode 101 protrudes from the outlet air passage surface 235 so as to be located closer to the inside of the outlet than the discharge electrode 102, the ion wind is not blocked inside the outlet air passage surface 235. It flows along the outlet air passage surface 235 toward the suction port side.
