送風口５から送出される。The operation in this configuration will be explained. When the air purifier is operated, dust-containing air is sucked through the intake port 4, coarse dust is removed by the pre-filter 11, and the ionizing electrode 1 and counter electrode 2
When the temperature reaches between 1 and 2, the minute dust particles are charged by the ion current. When this charged dust flows into the charged filter 8, it receives an electrostatic force due to the local electric field inside the charged filter 8, and is attracted to the fiber surface and collected. At this time, the surface of the charged filter 8 on the ionization electrode 1 side becomes high voltage due to the adhesion of charged dust. This increase in potential increases the electric field between the air-permeable ground metal oil 9 at the rear of the charged filter 8 and the surface of the charged filter 8, increasing the collection efficiency. In this way, dust is collected in the dust-containing air, and the clean air is sent out from the air outlet 5.

フィルタ１６で捕集される。FIG. 4 is a cross-sectional side view showing the schematic structure of another conventional electrostatic air cleaner. Components having the same configuration as those in FIG. 3 are given the same reference numerals and explanations will be omitted. In Figure 4,
The ground electrode 15 is formed in a wave shape, and the charged filter 16 is provided along the surface of the ground electrode 15 on the side of the air intake port 4 . Further, the ionization electrode 17 is arranged between the crests of the waves on the side of the intake port 4. The ground electrode 15 also serves as a counter electrode, and minute dust that has flowed in through the prefilter 11 is charged by the ion current flowing between the ground electrode 15 and the ionization electrode 17, and this charged dust is captured by the charged filter 16. collected.

配置して構成したものである。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a dust collecting section disposed downstream of an ionization section consisting of an ionization electrode and a counter electrode, with a two-layer structure consisting of a main filter and a ground electrode. A plurality of corrugated plates are arranged in a zigzag shape in a direction perpendicular to the inflow direction of the wind flowing from the ionization section, and the ridge lines of the crests of the corrugated plates are substantially parallel to the inflow direction of the wind,

Pressure loss can be reduced. In addition, since the charged dust flows along the flow path horizontally to the ridgeline of the corrugated sheet, there are no areas with large potential differences on the corrugated sheet surface, and the ridgeline of the corrugated sheet is long. Together, the dust can be collected uniformly over the entire main filter, and the life of the main filter can therefore be extended.
