The plasma electrode 900 may be disposed at the center of the first part 810 of the guide part 800, and thus, in the conventional plasma sterilizing purifier, the discharge effect of the plasma electrode was low due to the lack of moisture. In the plasma sterilization purifier 1000 of the present invention, the air humidified by the humidification module 700 is discharged by the plasma electrode 900 to increase the sterilization efficiency.

In summary, in the plasma sterilization purifier 1000 of the present invention, since the plurality of filters and the humidification module 700 are filtered by upward movement of the air in a compact structure stacked, the installation area is maintained and the humidification function is provided. There is an advantage (large space cover) that can be performed and the filtering effect can be increased at the same time.

In addition, referring to FIG. 4 , on the upstream side of the blowing module 500 on the static pressure distribution by the blowing module 500 , the density of the air far from the blowing module 500 is the highest, and the air moves in the blowing direction due to the density difference. And, on the downstream side of the blowing module 500, the density of the air near the blowing module 500 is the highest, and the air moves in the blowing direction due to the density difference. By disposing the HEPA filter module 300 in charge of the dust collection function far from the blowing module 500 on the upstream side and disposing the semi-filter module 600 close to the blowing module 500 on the downstream side, that is, the HEPA filter By disposing the module 300 and the semi-filter module 600 at a high density of air, the purification efficiency can be further improved.

Furthermore, in the main case 100, a passage network 150 through which the filtered air moves may be formed between the humidification module 700 and the guide part 800, and the passage network 150 has the largest circular shape in the center. The hole may be formed, and a plurality of small holes may be formed radially based on the outer periphery of the circle.

Accordingly, a large amount of the filtered air is distributed from the center of the first part 810 of the guide part 800 through the plasma electrode 900 directly through the large hole in the center of the passage network 150 to be discharged to the outside. A small amount other than the filtered air passes through the plasma electrode 900 indirectly through a plurality of small holes at the edge of the passage network 150 through the edge of the first part 810 of the guide part 800 . It can be distributed and discharged to the outside.

As a result, in the plasma sterilization purifier 1000 of the present invention, the flow of the filtered main air is not excessively disturbed, that is, by properly distributing, the advantage of being able to distribute evenly in one horizontal direction maximizing the plasma discharge effect is have.

On the other hand, in a modified example (not shown) of the plasma sterilization purifier 1000 of the present invention, when the moisture in the room exceeds the reference amount by the humidity sensor, the injection amount of the radiator 720 is reduced, and the injection direction of the radiator 720 is It can be automatically controlled to change (usually spray in a different direction) to the central direction in which the hollow of the chamber 710 of the humidification module 700 is formed (electronic control module). As a result, although the amount of humidification is reduced, the plasma discharge efficiency is increased and the sterilization function can be maintained.
