When the ozone (O ₃ ) is reacted with ultraviolet rays, the concentration of the ozone (O ₂ ) is decomposed into oxygen (O ₂ ) and active oxygen (O), and thus the concentration of the ozone (O ₃ ) may be reduced. The through hole 741 is preferably formed in the photocatalyst plate 740 to be irradiated.

As described above, the UV irradiator 720 may induce a photocatalytic reaction of the photocatalyst plate 740 and reduce ozone (O ₃ ) generation of the plasma reactant 730.

As described above, a plurality of through holes 741 of the photocatalyst plate 740 are formed on the same straight line with respect to each of the UV lamps 722 of the UV irradiator 720. By making the dispersion irradiation, the concentration of ozone (O ₃ ) can be prevented from being reduced and accordingly, the air efficiency of the plasma reactant 730 can be prevented from being reduced.

As shown, five through-holes 741 are formed in the same straight line as one UV lamp 722, but the number of the through-holes 741 is formed in the present invention is not limited thereto, and the air purification efficiency is not limited thereto. Subject to change.

Meanwhile, the ultraviolet rays are divided into UV-C bands of 1 nm to 280 nm, UV-B bands of 280 nm to 320 nm, and UV-A bands of 320 nm to 400 nm with respect to a wavelength range of 1 nm to 400 nm. Can be.

Herein, the ultraviolet wavelength for activating the photocatalytic reaction of titanium dioxide (TiO ₂ ) is in the range of 380 nm or less, and the ultraviolet wavelength in which decomposition of the ozone (O ₃ ) is activated is in the range of 280 nm to 320 nm. The UV irradiator 720 used is preferably irradiated with ultraviolet rays in the UV-B band having a wavelength in the range of 280nm to 320nm.

On the other hand, a plurality of fixing grooves 716 may be formed on the body 711.

In addition, a plurality of fixing rods 742 may protrude from the lower portion of the photocatalyst plate 740 in a vertical state, and a guide bar 743 extending horizontally in a 'c' shape may be provided at an upper portion thereof.

Here, the air inside the vehicle is passed through a space formed between the UV irradiator 720, the photocatalyst plate 740 and the plasma reactant 730 disposed in parallel with each other, so that the flow of air is not interrupted or is decelerated or decelerated on the way. The phenomenon can be prevented.

Meanwhile, the UV irradiator 720 should be spaced apart from the photocatalyst plate 740 by a distance corresponding to the total area of the photocatalyst plate 740 as shown in FIG. 12A. The sterilization and deodorization effect of the air can be maximized as it is set to be irradiated with the maximum luminous intensity with respect to the spaced distance.

Referring to FIG. 12B, the variable 'B' represents a diameter of the through hole 741 formed in the UV irradiator 720. In this experiment, the distance C between the through holes 741 is 1 mm. Fixed.

Table 1 below shows the UV according to the change of the distance A between the photocatalyst plate 740 and the plasma reactant 730 and the diameter B of the through hole 741 formed in the photocatalyst plate 740.

According to Table 1, for the change of the variables A and B, 200,000 to 250,000 anions are generated per 1cc and 150,000 to 170,000 cations are generated, so that the cations do not exceed the anion. It can be seen that, the ozone generation amount to maintain excellent low concentration characteristics of 0.004ppm which is 0.01ppm or less.

Since the anion generation amount disclosed in Table 1 shows superior characteristics of tens to hundreds of times compared to the amount of anion generation around the forest (500 to 3000 / cc) and the waterfall (5000 to 50000 / cc), The air purifier 100 for a vehicle can be seen that effective and excellent purification of harmful substances in the vehicle indoor air is possible.
