When the photocatalytic filter unit 52 and the antibacterial filter unit 56 include a frame supporting the mesh network, the cutting operation may be omitted.

When the photocatalytic filter unit 52 and the antibacterial filter unit 56 are attached to the air vent 24 with an adhesive tape such as a nonwoven tape, the area of the photocatalytic filter unit 52 is larger than the area of the introduction unit 21 of the air vent 24 . ) and it is preferable to cut so that the area of the antibacterial filter unit 56 is slightly larger.

When the photocatalytic filter unit 52 , the ultraviolet light emitting unit 54 , and the antibacterial filter unit 56 are prepared, the installer mounts the antibacterial filter unit 56 for sterilizing the air in the inlet 21 of the air vent 24 . It can be done (step S110).

After the antibacterial filter unit 56 is mounted, the installer may mount the ultraviolet light emitting unit 54 on the antibacterial filter unit 56 to irradiate ultraviolet rays (step S120). The ultraviolet light emitting unit 54 may be mounted to directly contact the surface of the central portion of the antibacterial filter unit 56 .

Thereafter, the installer may install the photocatalytic filter unit 52 for purifying the air passing through the air vent 24 by a photocatalytic reaction to be spaced apart from the antibacterial filter unit 56 by a predetermined interval.

When the photocatalytic filter unit 52 , the ultraviolet light emitting unit 54 , and the antibacterial filter unit 56 are installed in the air vent 24 , the installer installs the vehicle so that the power of the vehicle's power bank is supplied to the ultraviolet light emitting unit 54 . The terminal of the power bank and the power terminal of the ultraviolet light emitting unit 54 may be connected (step S140). The terminal of the power bank connected to the power terminal of the ultraviolet light emitting unit 54 connects the (+) pole to the fuse for the cigar jack in the car interior fuse box, and the (-) pole to the vehicle body is grounded.

The installation method of the sterilization and purification module 50 described above includes the steps of mounting the antibacterial filter unit 52 ( S110 ), mounting the ultraviolet light emitting unit 54 , and mounting the antibacterial filter unit 56 . , can be easily installed in a vehicle at low cost to sterilize and purify the indoor air of the vehicle.

As described above, although the embodiments have been described with reference to the examples and drawings, various modifications and variations are possible from the above description by those of ordinary skill in the art. For example, components such as the described device may be combined or combined in a manner different from the described method, or replaced or substituted by other components or equivalents.
