が生じ、イオン風が発生ずることが知られている。Conventionally, when a high voltage is applied between a discharge electrode (e.g., needle-shaped) and a counter electrode (e.g., plate-shaped) arranged to face it, a corona discharge is generated from the discharge electrode toward the counter electrode, and an ionic wind is generated. is known to occur.

塵器の機能をも有する。That is, the air near the discharge electrode is ionized by the corona discharge, and the ions move toward the counter electrode due to electrostatic force. In the process of this movement, many neutral molecules are repelled and a flow of molecules, or wind, is induced. This ion wind can achieve 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 the roller discharge, dust in the air is also ionized, and it also has the function of an electrostatic dust collector that collects this dust on the counter electrode.

を利用した空気清浄器と同程度のものが得られる。In FIG. 1, when a voltage (several KV to several tens of KV) is applied between the needle-shaped discharge electrode 1 and the flat counter electrode 5 by the DC power source 8, dielectric breakdown occurs at the tip of the needle-shaped discharge electrode 1 to which the negative voltage is applied. As a result, a corona is generated, and a corona discharge is generated toward the flat counter electrode 5. This phenomenon is! When a voltage is applied between an electrode that is close to a point like 1 and an electrode that has a relatively flat surface like a plate, a significantly unequal electric field is generated between the two electrodes.
Corona is generated at a location where the electric field strength is spatially strong, that is, at the tip of the needle electrode 1. Ions are generated by this discharge, that is, corona discharge, and among these, negative ions move from the discharge electrode l toward the counter electrode along the lines of electric force. In the process of this movement, the ions collide with a large number of neutral gas molecules, and these neutral gas molecules are driven from the needle-shaped discharge electrode 1 to the plate-shaped counter electrode 5 as shown by arrow A in FIG. A wind is generated. This ion wind flows through the needle-shaped discharge electrode 1
The wind speed changes depending on the distance between the two electrodes, the distance between the needle discharge electrode 1 and the flat counter electrode 5, the voltage applied between both electrodes, etc., but if these are properly matched, the speed will be several m/s.
It is easy to do things without blowing the wind. In fact, if there is a wind of several m/s, if the ventilation area of the flat counter electrode 5 is made to be about the same as the aperture area of the dust collection part of an automobile air purifier that uses a motor and a fan, the air volume will be You can get something similar to an air purifier that uses a motor and fan.
また、上記両電極間のコロナ放電は、イオン風を発生さ

５上に集塵させる。Further, the corona discharge between the two electrodes generates an ion wind, and at the same time, dust in the air is charged and collected on the flat counter electrode 5.

。At this time, the electric field forming electrode 6 has a protrusion 6a for taking out the potential.
The electric potential of the same polarity as the discharge electrode 1 (negative electrode in this case) is created by -
are doing. That is, an electric field is formed between the electric field forming electrode 6 and the counter electrode 5 at right angles to the flow of the ion flow. Therefore, when the dust negatively charged due to corona discharge passes through the space between the counter electrode 5 and the electric field forming electrode 6, the electric field formed between the electric field forming electrode 6 and the counter electrode 6 causes the dust to The dust is attracted toward the opposite direction and efficiently collected on the counter electrode 5.
次に本例における電界形成電極６の放電電極１に対向す

において前記帯電距離をｌとする。Next, experiments conducted by the present inventors regarding the distance between the end 6a of the electric field forming electrode 6 facing the discharge electrode 1 and the end 5a of the counter electrode 5 (hereinafter referred to as charging distance) in this example A detailed explanation will be provided based on the results. r FIG. 2 is a diagram showing the principle of the air purifier of the present invention, and in FIG. 2, the charging distance is assumed to be l.
ただし、第２図に示す電界形成電極６は、第１図のもの
と異なり、突起６ｂが形成されていないものとする。However, the electric field forming electrode 6 shown in FIG. 2 is different from that shown in FIG. 1 in that it does not have a protrusion 6b formed thereon.

２酊以下になると急激に風速■が低下することが解乞。As shown in FIG. 3, the shorter the charging distance p, that is, the closer the electrode forming electrode 6 is to the discharge electrode 1, the higher the intermediate potential can be obtained;
Therefore, the potential V2 decreases as the distance increases. Here, in order to obtain high dust collection efficiency, a strong electric field strength, that is, a high potential V2 is required. Therefore, in order to improve the dust collection efficiency, the electric field forming electrode 6 should be replaced with the discharge electrode 1.
1. By the way, when the electric field forming electrode 6 is brought closer to the discharge electrode 1, the speed of the ion wind generated according to the above-mentioned principle decreases. In particular, the charging distance l shown in FIG.
Please note that when the wind speed drops below 2, the wind speed decreases rapidly.

る。The reason for this is that since a potential of the same polarity as that of the discharge electrode 1 is generated in the electric field forming electrode 6, ions that should go toward the counter electrode 5 are repelled by the corona discharge, and the flow of ions is obstructed. By doing so. Therefore, in order to obtain the wind speed, it is necessary to set the charging distance IQlli6 in FIG. 3 to 2IllI or more. However, in this case, a sufficient potential V of the electric field forming electrode 6 cannot be obtained. Therefore, as in the present invention, by providing a protrusion 6b as shown in FIG. 1 on one end of the electric field forming electrode 6, if the high intermediate potential is made small enough not to be adversely affected, sufficient wind speed and dust collection performance can be achieved. is obtained.

ることができる。Incidentally, when the performance was compared with that when the protrusion 6a for taking out the potential was not provided, the following was confirmed. In Fig. 3, when the fin is β-1, the ion wind speed V 1 = l m/s, and the voltage for collecting dust is 2 = 2.
It was 5KV. However, when the protrusion 6b is at the position l-0 and the end 6a of the electric field forming electrode 6 is at the position β-3IIm, the wind speed V=1.5 m/s and the potential V2#3.5.
ν can be obtained, and both wind speed and dust collection performance can be increased.

By alternately arranging a plurality of flat plate-shaped electric field forming electrodes 6, the dust collection efficiency of the counter electrode 5 is increased, so there is no need to arrange a special dust collection electrode downstream of the counter electrode 5, and the air It is possible to downsize the purifier. Further, since the electric field forming electrode 6 does not require a special power source for dust collection, it can be further reduced in size and weight.
