Ozone cleaning method air cleaner

The present invention relates to an Ozone cleaning method of air cleaner, which includes the following steps: A. guiding external air, B. proceeding Ozone oxidation, and C. releasing clean air. By using an air-flow guiding device, air is guided from an air-inlet on the main body of air cleaner into a mixing chamber inside the main body of air cleaner. The Ozone is generated by an Ozone generating unit and then is mixed with the air in the mixing chamber. The Ozone/air mixture flows into the action chamber inside the main body of air cleaner to proceed an oxidation, and then flows into the buffer chamber inside the air cleaner for reducing residual Ozone to oxygen by using an Ozone-eliminating unit. Finally, the cleaned air is released from the air-outlet on the main body of air cleaner.
