At the same time, an ionic wind is generated between the accelerating electrode 6 and the counter electrode 5, and the dust in the dust-containing air is charged and collected on the counter electrode 5 using the high electric field between the accelerating electrode 6 and the counter electrode 5.

特に複雑になるという問題点もあった。However, in the conventional configuration, in order to generate high electric fields between the ionization electrode 4 and the counter electrode 5 and between the counter electrode 5 and the acceleration electrode 6, the high voltage power supply 8 has two types of high voltage output parts 8a. It is necessary to provide a ground connection part 8b and a ground connection part 8c, and to connect each electrode to each electrode through a contact point, which not only complicates the structure but also requires the use of inorganic insulating material for high voltage connections for safety reasons. However, there was a problem in that the manufacturing cost was high. Further, since the dust collecting section consisting of the counter electrode 5 and the accelerating electrode 6 needs to be removably attached to the rib 7 of the upper holding case 3, there is also the problem that the structure of the contact section becomes particularly complicated.

In the section, a high electric field causes dielectric breakdown of the air around the ionizing electrode 4, and ions generated by corona discharge move along the electrical line shown by the broken line, and in the process of this movement, many neutral molecules are generated. This causes a flow of molecules, the so-called ion wind. At this time, the charges of a large number of ions moving toward the accelerating electrode 9 accumulate on the accelerating electrode 9, increasing its potential, and generating a high electric field between it and the counter electrode 5. Due to the electrostatic force caused by this high electric field, the dust charged in the ionization section moves toward the counter electrode 5 and is deposited on the counter electrode 5 for collection.
