The present invention relates to an electrostatic precipitating filter of a packaged air conditioner, and particularly, to a two-stage charging method in which a collecting plate is densely installed at the same cross-sectional area of a suction port so that the cross-sectional area is expanded and a high voltage is applied to the collecting plate corresponding pole of the collecting unit. The present invention relates to an electrostatic precipitating filter of a packaged air conditioner to obtain a high dust collection rate.

In general, a packaged air conditioner sucks external air from the inlet formed in the lower part of the air conditioner, passes through an electrostatic precipitating filter, filters dust, etc., and then heats the heat exchanger to the upper outlet by the blower fan. It is configured to perform a series of operations to be blown, which will be described in more detail based on FIGS. 1 to 3 as follows.

The heat exchanger 2 is inclined inside the air conditioner main body 1, and a drain fan 3 for collecting condensate is provided at the lower end of the heat exchanger 2, and the lower side of the heat exchanger 2 is provided. The electrostatic precipitating filter 4 which has the same inclination is provided in it. In addition, the filter 5 is built in the lower part of the main body 1 and the blower fan 6 installed on the upper part of the main body 1 operates to primarily filter dust in the air.

On the other hand, the electrostatic precipitating filter 4 has a negative electrode dust collecting plate 9 in which the positive electrode is arranged in the case 7 with the discharge line 8 and the discharge line 8 coincident in the same circumference. The discharge line 8 and the dust collecting plate 9 are arranged in series in a plurality.

Referring to the operation of the conventional packaged air conditioner having the above-described configuration, the electrostatic precipitating filter 6 will be described. By operating the blower fan 6 in the main body 1, the air in the air in the filter 5 of the inlet port is operated. The first and the like dust is first filtered, and dust of 1 mm or less is collected while passing through the electrostatic precipitating filter 4, which means that the dust passing through the filter 5 is discharged in the electrostatic precipitating filter 4. 8) Charged to the positive pole by the electrons emitted from the negative electrode and collected in the dust collecting plate 9 having the polarity, and then only the filtered pure air is transferred to the heat exchanger 2 by the blower fan 6 so that the heat exchange is performed. The cold air passing through the machine 2 acts to blow a series of air to the outlet of the upper part of the main body 1.

However, the conventional electrostatic precipitating filter 4 as described above has a problem that the apparatus becomes larger and causes a cost increase by lengthening the flat dust collecting plate 9 in order to increase the dust collection rate as the flow rate of the air conditioner is high. In order to prevent dielectric breakdown, the distance between the discharge line 8 and the collecting plate 9 is maintained at about 6-12 mm to form an electric field, whereby the collecting area of the collecting portion is reduced in the same plane, thereby reducing dust collection efficiency. Since the collecting plate 9 of the collecting part is composed of only the negative pole, an electric field is not formed between the ground plates 9, and thus, the first charged particles are collected only by the coulomb force, so that the collection collecting efficiency decreases. Due to this, only the pure air in the heat exchanger (2) can not be heat-exchanged and is cooled with residual dust in the air and is re-extracted into the room by the blower fan (6). There have been problems such as causing.

Therefore, the present invention is to solve the problems described above, it is possible to compactly reduce the gap between the collecting plate and the corresponding electrode plate by coating the corresponding electrode plate of the collecting portion with an insulating material, it is possible to install a large amount of collecting plate By constructing a two-stage charge system that extends the cross-sectional area of the plate and applies a high voltage to the corresponding electrode plate, an electric field is formed on the collecting plate and the corresponding electrode plate, and the charged particles of the dust are collected on the collecting plate under the influence of the electric field.
