The process of ion sterilization refers to the positive and negative ion emitting electrodes ionizing water molecules in the air under the action of high voltage to produce positive ions and negative ions. The positive and negative ions undergo chemical reactions in the air to produce active substances. The process of decomposition by microorganisms such as viruses. After the ion sterilization process, it can remove fungi, planktonic bacteria, viruses and other pollutants in the air.

If this principle is applied to air conditioners, bacteria, fungi, viruses and other microorganisms inside the air conditioner can be decomposed to make the interior of the air conditioner cleaner. At the same time, during the ion sterilization process, due to the strong corona discharge between the high-voltage electrodes, a certain concentration of ozone is generated. If the operation of the air-conditioning fan is combined, the ozone can penetrate into the evaporator and the inner corner of the air duct to kill bacteria, eliminate odor and purify Air.

In the prior art, air conditioners generally have a self-cleaning function, such as the cold expansion self-cleaning method, that is, to control the cooling operation of the air conditioner, and control the heating and defrosting of the air conditioner after the surface of the evaporator of the air conditioner is frosted; another example is the high-temperature steam self-cleaning method, that is, to control The steam generating device inside the air conditioner generates high-temperature steam, which cleans the surface of the evaporator.
