The indoor unit of the present invention will be described in detail with further reference to fig. 1 to 6.

Thus, the active particles can act on pathogenic microorganisms in the air through the flow of the airflowThe sterilization device has a killing effect, and hardly has an inactivation effect on pathogenic microorganisms attached to the culture dish; long-lived active species (e.g. O)3、O2-, excited state N2、NO、H2O2Etc.) assist in sterilization in this type of plasma, these minute amounts of O being within safe thresholds3And a large number of excited states N2Etc. may flow with the airflow and diffuse into the room, inactivating pathogenic microorganisms. Meanwhile, after the negative ions are generated, the negative ions are attached to the surfaces of dust particles, smog, dust, PM2.5 and the like in the air to form heavy ions for sedimentation, and the negative ions also have the effects of reducing dust and PM2.5 in the air.
Therefore, when the first air outlet 4 supplies air, the high-energy negative ions and the short-life ions purify and sterilize the air in the air-conditioning air supply passing through the ion field, and the long-life active ions reach the negative pressure area 7 under the driving of the air-conditioning air supply, are secondarily guided by the air-conditioning air supply polymerized after passing through the air-out baffle column 2, and are sent to all parts of the room, so that the air purification and sterilization functions are realized.
