本発明は、空気清浄器の逆風手段として有効な
イオン風を利用したイオン風起風装置。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention is an ion wind fan device that utilizes ion wind, which is effective as a back wind means for an air purifier.

発生することが知られている。(Prior Art) Conventionally, when a high voltage is applied between a first electrode body, which is a discharge electrode, and a second electrode body, which is a counter electrode, and which is arranged to face the first electrode body, the first electrode body moves from the first electrode body to the second electrode body. It is known that corona discharge occurs toward the Earth, generating ion wind.

イオン化され、この塵埃を第２電極体上に集塵す
る正電式集塵器の機能をも有する。 That is, the air near the first electrode body is ionized by the corona discharge, and the ions move toward the second electrode body by the positive electric power. In the process of this movement, many neutral molecules are repelled and a flow of molecules, or wind, is induced.
This ion wind has a wind speed of several meters per second, and depending on how it is used, it is possible to obtain a sufficient amount of air. Furthermore, during corona discharge, dust in the air is also ionized, and it also has the function of a positive electrostatic dust collector that collects this dust on the second electrode body.

容易に設計できる。 Therefore, if this ionized wind can be used, the blowing section and the dust collecting section can be integrated, eliminating the need for a blower with a fan and a motor, and making it possible to make the air purifier smaller and lighter. In addition, since there are no moving parts and the duct can be set freely, when used in an air purifier, the degree of freedom in designing the shape is increased, and thin products can be easily designed.

る事もある。(Problems to be Solved by the Invention) However, when the present inventors conducted detailed research in order to apply an ionic wind air purifier to a small air purifier installed in a passenger car, etc.,
The ion wind generating area also needs to be small, and there should be enough space between the first electrode body (metal wire, etc., several tens of μm thick), which is the discharge electrode, and the wall of the duct, etc., made of an insulator, etc. I confirmed that this is not possible. Conventionally, in such an ion wind generating section, among the ions generated near the first electrode body, ions having an electrode opposite to the second electrode body are pulled toward the second electrode body to generate an ion wind. and gives charge to the second electrode body. On the other hand, ions having the opposite polarity to the ions give charge to the first electrode body, thereby forming an electric circuit including a power source. However, as mentioned above, if the distance between the first electrode body and the wall is short, the ions that should give charge to the first electrode body will move towards the wall (capacitively at ground potential). The present invention has been discovered. At this time, since it has the same polarity as the second electrode body, the direction of movement is opposite to that of the second electrode body, that is, the direction opposite to the flow of the ion wind. On the other hand, the ions that were being pulled toward the second electrode body also move toward the wall. Therefore, from the above, near this wall, the flow of ions will flow not only in the direction of the second electrode body, but also in the opposite direction, and the flow of ion wind will be obstructed, resulting in the worst case scenario. In some cases, backflow development may occur.

い。 The ion repelling electrode 4 in the ion wind generating section is such that a distance between the ion repelling electrode 4 and the discharge electrode is approximately equal to or greater than the distance between the discharge electrode 1a and the counter electrode 2a. Furthermore, the voltage applied to the ion repelling electrode 4 is an intermediate voltage between the voltages of the discharge electrode and the counter electrode, but approximately 1/4 to 1/2 of the voltage required for this discharge is appropriate and desirable. It is better if it can be used in common with the electric field forming voltage for dust collection.

In FIGS. 1 and 5, a high voltage (several kV to several
10kv), the difference in electrode wire diameter (40μ and
400μ), an unequal electric field is formed between the two electrodes, and the electric field is concentrated around the sharp 40μ discharge electrode 1a, causing corona discharge. This corona discharge generates ions of both positive and negative polarities, but most of the negative ions with the opposite polarity to the discharge electrode 1a are absorbed by the discharge electrode 1a, and only the positive ions with the same polarity are absorbed by the opposite electrode 2a. I am drawn to it. In the process of being attracted to the counter electrode 2a, these positive ions collide with a large number of neutral gas molecules, and by giving kinetic energy to these neutral gas molecules and driving them, the positive ions and neutral gas molecules are separated. Both generate wind toward the counter electrode 2a.

As shown in FIGS. 2 and 2, dust can be collected by installing a dust collection electrode 3 on the downstream side of the flow.
At this time, since almost no current flows through the electric field forming power source for dust collection, it can be used in common with the ion repulsion power source 7. Therefore, when the dust is charged with positive ions in the ion wind generating section and passes through the electric field formed between the electrode 3a applied with negative polarity by the power source 7 and the grounded electrode 3b, The dust is collected on the electrode 3 having a polarity different from that of the dust.

されている。 Therefore, the dirty air inside the vehicle is located at arrow D in Figure 3.
1. As shown in D2, the dust is sucked in from the suction ports 10A and 10B, and after being collected by the dust collection electrodes 3a and 3b,
The purified air is blown out into the vehicle interior from the air outlet 10C as shown by the arrow. However, among the negative ions generated around the discharge electrode 1a, those near the wall made of an insulator are not only absorbed by the grounded discharge electrode 1a, but also absorbed by the wall (capacitance-wise, it is not connected to the ground). Objects that move toward the same direction also occur. At this time, since the negative ions have the same polarity as the counter electrode 2a, the negative ions have the same polarity as the counter electrode 2a.
However, since the ion repelling electrode 4 has the same polarity as the negative ions, the negative ions near the wall also move toward the discharge electrode 1a. Absorbed. In this way, more ion wind can be generated because the movement of negative ions to the air upstream side of the discharge electrode, which is a major factor in the backflow phenomenon required in the case where the ion repelling electrode 4 is not provided, is eliminated. FIGS. 6 and 7 are examples of experimental results using the ion repelling electrode. In Figure 7, which is a diagram of its principle,
The distance l1 between the discharge electrode 1a and the counter electrode 2a is 10
mm, the discharge electrode pitch l2 is 10 mm, the counter electrode pitch l3 is 5 mm, and the discharge electrode and the counter electrode are each 1:
They are arranged in a staggered pattern. The ion repelling electrode 4 is a metal band with a width of 5 mm exposed on the inner surface of the duct, and the discharge electrode 1a and the ion repelling electrode 4
The distance l4 to the end on the discharge electrode side is set to 11 mm.
以上の様な構成で、放電電極１ａと対向電極２

FIG. 6 shows the change in wind speed when a voltage of V 2 is applied to the V 1 ion repelling electrode during period a.

いることが解る。 As shown in Figure 6b, when there is no ion repelling electrode as shown in Figure 6, that is, V 2 = 0 [kv]
It can be seen that the wind speed is improved for the same V 1 when V 2 =2.5 [kv] is applied to the ion repelling electrode 4.

あるので、電源７にはほとんど電流が流れない。
従つて、電源７は集塵用電源と共用できる。 Also, at this time, the ion repelling electrode 4 is the counter electrode 2a.
Compared to the above, the distance from the discharge electrode 1a is larger, and
Since the voltage applied during this time is also small, positive ions due to corona discharge generated around the discharge electrode 1a do not reach the discharge electrode 1a, and negative ions are only repelled, so that almost no current flows through the power source 7.
Therefore, the power source 7 can be used in common as a power source for dust collection.

In this embodiment, as the ion repelling electrode 4, a thin metal film 40 (aluminum foil number of about 10 μm) is placed on the inner surface of the duct 5 on the upstream side of the discharge electrode 1a (on the side opposite to the counter electrode 2a with respect to the discharge electrode 1a). It is attached by adhesive or the like at a constant distance from the discharge electrode 1a. Other configurations and structures are the same as in the first embodiment.

ある。 FIG. 8 shows a third embodiment of the present invention. In the third embodiment, a wire mesh 40 is used as an ion repelling electrode. At this time, the wire mesh 40 is connected to the discharge electrode 1a.
and the discharge electrode 1a, or the voltage applied by the power source 7 is lower than the voltage applied to the electrode 6. Alternatively, by increasing the distance and decreasing the voltage, the ion repelling electrode 4 is moved from the discharge electrode 1a.
It is designed to prevent corona discharge from occurring.

The function and effect are the same as in the first embodiment, but as in this embodiment, by installing a wire mesh on the upstream side of the ion wind, it can be used as a pre-filter to remove relatively large debris such as lint, and remove ions. It is possible to prevent obstruction at the wind generating part.

れる。 FIG. 9 shows a fourth embodiment of the present invention. Performing positive discharge to reduce ozone generation is
As mentioned before, in this embodiment, although the same positive discharge is performed, unlike the first embodiment, the discharge type is such that the discharge electrode 1a is the positive pole, the counter electrode 2a is the negative pole, and is grounded. At this time, the ion repelling electrode 4 is connected to ground. Furthermore, in this example,
The power source 7 is used only for forming an electric field such as dust collection.

It goes without saying that the same electrodes as in the second and third embodiments can be used in this embodiment as well. In particular, in this example,
If a wire mesh like the one in the third embodiment is used as the ion repelling electrode, the wire mesh can be grounded to provide a safer configuration against intrusion from the outside.

る。(Effects of the Invention) As described above, according to the present invention, since the ion repelling electrode with the opposite polarity to the discharge electrode is provided on the air upstream side of the discharge electrode, ions of the same polarity as the discharge electrode generated in the discharge electrode are Even if the ions move to the air upstream side from the discharge electrode, they are repelled by the ion repelling electrode toward the discharge electrode and absorbed by the discharge electrode. Therefore, since backflow of air on the upstream side of the discharge electrode is prevented, a large wind speed can be obtained even when the distance between the discharge electrode and the inner wall of the case is small, and as a result, it is possible to downsize the ion wind blower. There is an effect.
