As shown in FIG. 1, the ozone generator 11 includes a case 12 having an inlet 12 a on the back side and an outlet 12 b on the lower side, and a dielectric plate 13 disposed inside the case 12. The dielectric plate 13 is electrically connected to the power supply unit 10 and, as shown in FIG. 2A, has a surface formed of a conductive member and has a pair of opposing comb-shaped members. The surface electrodes 13a and 13b are formed by screen printing. Further, the air blown out from the blower fan 9 by the inflow port 12a formed on the back side of the case 12 flows toward the blowout port 6 on the upper surface of the main body and flows into the case 12 from the inflow port 12a. It is supposed to.
[0015]
When a high voltage is applied from the power supply unit 10 to any of the surface electrodes 13a and 13b of the dielectric plate 13, an arc-shaped surface discharge occurs between the opposing surface electrodes 13a and 13b. Oxygen in the air in the case 12 is converted into ozone by creeping discharge.

The ozone decomposing catalyst made of manganese dioxide decomposes the ozone discharged from the ozone diffusion pipe 14 together with the odor component contained in the air. These ozone decomposition catalysts also absorb a small amount of secondary nitrogen oxides generated when the ozone generator 11 generates ozone.
[0019]
Next, the operation of the above-described air purifier will be described. When a high voltage is applied from the power supply unit 10 to the dielectric plate 13 of the ozone generator 11, an arc-shaped surface discharge occurs between the surface electrodes 13a and 13b, and ozone is generated inside the case 12. appear. The generated ozone flows into the ozone diffusion pipe 14 through the outflow port 12b provided on the lower surface of the case 12, and is diffused left and right by the upper horizontal pipe 15a, while the plurality of vertical branches branch therefrom. It flows into the pipe 16.
