The electrostatic precipitator may be an electrostatic filter of an electrostatic precipitator method.

Air introduced from the outside along the F direction through a blowing fan provided upstream or downstream of the electric precipitator may pass through the dust collecting sheet 10 and be discharged to the outside again.

The dust collecting sheet 10 may be formed by stacking a plurality of electrodes. The dust collecting sheet 10 may include a high voltage electrode 100 as a positive electrode and a low voltage electrode 200 as a negative electrode. Each of the high voltage electrode 100 and the low voltage electrode 200 may be provided in plurality. The high voltage electrode 100 and the low voltage electrode 200 may be alternately disposed and stacked.

When a constant voltage is applied between the high voltage electrode 100 and the low voltage electrode 200, an electric field may be formed between the high voltage electrode 100 as a positive electrode and the low voltage electrode 200 as a negative electrode. Here, the positive electrode and the negative electrode may represent a high potential level as a plus electrode and a low potential level as a negative electrode based on the potential difference between the two electrodes.

The high voltage electrode 100 may include a dielectric layer 101 and a conductive electrode layer 103 provided inside the dielectric layer 101 . The dielectric layer 101 may include an upper dielectric layer 101a disposed above and a lower dielectric layer 101b disposed below the conductive electrode layer 103 .

The dielectric layer 201 may include an upper dielectric layer 201a disposed above the conductive electrode layer 203 and a lower dielectric layer 201b disposed below.

To distinguish the high voltage electrode 100 from the low voltage electrode 200, the dielectric layer 101 of the high voltage electrode 100 may be referred to as a first dielectric layer, and the dielectric layer 201 of the low voltage electrode 200 may be referred to as a second dielectric layer. have.

Also, the conductive electrode layer 103 of the high voltage electrode 100 may be referred to as a first conductive electrode layer, and the conductive electrode layer 203 of the low voltage electrode 200 may be referred to as a second conductive electrode layer.

Air may pass through the dust collecting sheet 10 along the F direction and be discharged to the outside again. Air may pass between the high voltage electrode 100 and the low voltage electrode 200 stacked in plurality. Before the air passes through the dust collecting sheet 10, pollutants in the air may be charged to a positive pole (+) or a negative pole (-) through discharge. An opening 110 may be formed in the dielectric layer 101 of the high voltage electrode 100 so that air can be discharged before passing through the dust collecting sheet 10 . Through the opening 110, the high voltage electrode 100 may expose a portion of the conductive electrode layer 103 to the outside. The opening 110 may be formed at a portion where the upper dielectric layer 101a and the lower dielectric layer 101b overlap each other. The opening 110 may be formed to have a straight line shape on one side of the dielectric layer 101 . In this case, one side may be an upstream side of the dielectric layer 101 based on the F direction in which air flows. The conductive electrode layer 103 may adhere to an upstream side where the opening 110 is formed in the dielectric layer 101 . Through this, the conductive electrode layer 103 may be exposed to the outside through the opening 110 .

Air passing between the high voltage electrode 100 and the low voltage electrode 200 may be discharged in contact with the conductive electrode layer 103 exposed through the opening 110 . Pollutants in the air can be charged with a positive pole (+) or a negative pole (-) through discharge. When the contaminant is charged with a positive pole (+), the contaminant may be attached to the low voltage electrode 200, which is a negative electrode. When the contaminant is charged with a negative pole (-), the contaminant may be attached to the high voltage electrode 100, which is a positive electrode. Through this, contaminants in the air can be removed. Thus, the air that has passed through the electric precipitator can be discharged in a clean state in which contaminants are removed.

That is, the charging part that charges the dust in the air is between the first conductive electrode layer 103 and the low voltage electrode 200, a part of which is exposed by the opening 110 formed on the upstream side of the first dielectric layer 101 based on the F direction. can be formed in Accordingly, the charging unit may be formed on an upstream side of the plurality of high voltage electrodes 100 and the plurality of low voltage electrodes 200 .

The charging unit and the dust collecting unit may be integrally formed on the plurality of high voltage electrodes 100 and the plurality of low voltage electrodes 200 by the first conductive electrode layer 103 and the second conductive electrode layer 203 integrally formed.

As described above, when the air is discharged through the opening 110 formed in the high voltage electrode 100 forming the dust collecting sheet 10, a separate charging unit is not required, and the electric dust collector can be manufactured slim. In addition, since the number of component parts can be reduced, material costs can be reduced. In addition, since the assembly process of each part can be reduced, manufacturing cost can be reduced. In addition, since the area of the dust collecting part formed by the dust collecting sheet 10 can be increased compared to the same area, the dust collecting efficiency can be improved and the dust collecting capacity can be increased.

That is, it may be the case that another dust collecting sheet 10 is disposed on the downstream side of the downstream side of the dielectric layer 101 based on the F direction (see FIG. 3). The opening 110 may be formed at a portion where the upper dielectric layer 101a and the lower dielectric layer 101b overlap each other.
