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.

The plasma sterilization process mainly comprises the following aspects:
1. penetration effect of high-speed particles: the shearing force generated on the surface of the microorganism is larger than the surface tension of the cell membrane of the microorganism;
2. electric field effect: when the average electric field strength exceeds a certain strength, the bacterial cell membrane can be punctured;
3. ultraviolet light action: ultraviolet light can be emitted in the process of generating the plasma and is absorbed by nucleic acid such as DNA and the like to play a role in sterilization;
4. action of energetic particles and active radicals: reacting with protein and nucleic acid in the body of bacteria.

Specifically, the high-voltage electric module is an internal high-voltage power supply conversion part and is used for processing input direct current or alternating current through an EMI (electro magnetic interference) processing circuit and a lightning stroke protection circuit, increasing low voltage to alternating current high voltage through a pulse oscillation circuit, circuits such as overvoltage current limiting, high-low voltage isolation and the like, rectifying and filtering the alternating current high voltage through a special grade negative ion material to obtain pure direct current negative high voltage and pure direct current positive high voltage, and connecting the direct current negative high voltage and the direct current positive high voltage to the plasma emission module 3 through an electrified wire; the high-voltage module is assembled behind a wall-mounted air conditioner cover shell, the higher the voltage of the plasma emission module 3 is, the stronger the ionization capacity is, the larger the generated plasma quantity is, but the higher the output voltage is, the more complicated the internal boosting circuit is required, the higher the requirements on components are, and the higher the cost is, so comprehensive consideration is required.
In one possible embodiment, the ion outlet 21 is a plurality of small holes arranged side by side.
The setting mode has the advantages that: a plurality of small holes are arranged in parallel on the inner side and the outer side of the air outlet baffle column 2 and are used as ion outlets 21, and plasma can be emitted from the ion outlets 21; simultaneously, a plurality of apertures that set up side by side, shape and outward appearance are all more regular, can not exert an influence to indoor whole air current.
In an embodiment of the present invention, after the indoor unit is normally turned on, regardless of whether the user selects the cooling mode or the heating mode, the indoor unit is operated in the maximum air supply mode, as shown in fig. 5 and 6, that is, the air outlet pillar 2 moves backward to open the first air outlet 4, the air deflector 6 rotates at a small angle (e.g., 45 °) to open the second air outlet 5, both air outlets supply air, when the indoor temperature reaches the set temperature, if the user selects the cooling mode, the air outlet pillar 2 moves backward, the first air outlet 4 is opened, a negative pressure region 7 is formed, cold air is blown out, and cold air is blown upward or blown flatly, and the air deflector 6 of the second air outlet 5 is closed; if the user selects the heating mode, the air outlet baffle column 2 moves forwards, the first air outlet 4 is closed, the air deflector 6 of the second air outlet 5 rotates at a large angle (for example, more than 80 degrees), the second air outlet 5 is opened, and hot air is blown downwards.
Particularly, the sterilization efficiency of the plasma is higher than that of an ultraviolet lamp with the same cost, the plasma module is arranged inside the air outlet baffle column 2, and the outer side of the air outlet baffle column 2 is provided with a plurality of small holes, so that the function of the plasma module can be seen, but the whole function and the safety of the indoor unit are not influenced. Meanwhile, the safety of the plasma is higher than that of ultraviolet rays, and in the process of applying plasma sterilization and purification, active ions contained in the plasma have a plurality of benefits for human bodies, such as blood fat regulation, blood pressure regulation, cardiac function improvement, lung capacity improvement, respiratory function improvement and the like.
In summary, the indoor unit of the embodiment of the present invention is provided with two air outlets, the first air outlet 4 is opened and closed by moving the air outlet pillar 2 back and forth, the air outlet pillar 2 is a hollow structure, the front and rear sides of the air outlet pillar are provided with the ion outlets 21, and the plasma emission module 3 is disposed inside the air outlet pillar 2. The plasma emission module 3 comprises an ion emission unit and a grounding unit 32, the ion emission unit and the grounding unit 32 form an ion field, the plasma emission module 3 is connected with a high-voltage module to obtain direct current high voltage, and ionized air obtains plasma. The short-life plasma purifies and sterilizes the air passing through the ion field in the ion field, and the long-life plasma is emitted to all places indoors along with the air supply of the air conditioner. When first air outlet 4 air supply, air-out bumping post 2 moves back and opens, can realize the reposition of redundant personnel and the polymerization of air conditioner air supply, forms negative pressure region 7, and the longer plasma of life-span reachs negative pressure region 7 under the air conditioner air supply effect to further the drainage transmission is indoor everywhere by the air conditioner air supply, the transmission distance is farther, and the transmission effect is better. When the second air outlet 5 supplies air, because the front side and the rear side of the air outlet baffle column 2 are both provided with the ion outlets 21, the plasma can still diffuse into the indoor and the indoor machine through the ion outlets 21, and the air supply of the second air outlet 5 of the indoor air machine is purified and sterilized.
