The present invention relates to a photocatalyst filter module and an air cleaner having the same, and more particularly, to a photocatalyst filter module and an air equipped with the same according to an appropriate structure, arrangement, and configuration between an ultraviolet light source and a photocatalyst filter. It relates to a purifier.

Referring to FIG. 1A, a configuration of a deodorization filter using a conventional ultraviolet lamp is shown as a perspective view, and referring to FIG. 1B, a cross-sectional view of a conventional deodorization filter is illustrated. (Republic of Korea Patent Publication No. 10-2004-0075457, published August 30, 2004, Name; Air purifier with a deodorizing filter)

As shown in FIGS. 1A and 1B, the deodorizing filter 40 includes a filter case 43, two deodorizing members 42 inside the filter case 43, and two ultraviolet rays irradiating ultraviolet rays with the two deodorizing members 42. It comprises a spacer 44 between the lamp 41, the two ultraviolet lamps 41 and the two deodorizing members 42.

Open filter case 43 is composed of two to be separated and coalesced for accommodating the deodorizing member 42. In addition, the two deodorizing members 42 are installed to be spaced apart from each other inside the filter gauge 43. The deodorizing members 42 are made of paper and coated with a photocatalytic material and penetrated in a lattice form for air circulation.

The two ultraviolet lamps 41 are disposed on both sides of the separation space 48 to evenly irradiate the two deodorizing members 42 with ultraviolet rays. And the spacer member 44 is installed in the center between the two deodorizing members 42, to prevent deformation and sag of the two deodorizing members 42 made of paper so that the UV lamp 41 is properly maintained. In addition, the engaging projection 47 is formed at the end of each support 45 in contact with the deodorizing member 42 so that the spacer 44 is not separated from the initial installation position.

As described above, the conventional air cleaner deodorizing filter is supported by two deodorizing members inside the filter case to prevent deformation through the separating member, and at the same time, the deodorizing member and the ultraviolet lamp are kept properly spaced, so that the light irradiated from the ultraviolet lamp It can be evenly distributed throughout the deodorizing member, and through this, the photoreaction of the photocatalytic material can be actively performed as a whole, so that the deodorizing efficiency is improved and shows excellent deodorizing effect even after long-term use.

However, since the conventional deodorizing member is basically made of a paper material, it is easy to be damaged by impact during handling, and if it is exposed to moisture for a long time, such as during the rainy season, even if the spacer member is adopted, deformation is inevitable due to the characteristics of the material. Deflections occur in sections other than located. In addition, the deodorizing member having a certain thickness is formed in a lattice shape in consideration of the air distribution, so that the light emitted from the UV lamp is disturbed by the adjacent grid wall, so that the shade is generated in a condition where the thickness is far from the UV lamp. In order to uniformly irradiate ultraviolet rays, there is a problem that more light sources are required.

In addition, the UV lamp used as a light source of ultraviolet light requires an inverter for driving, which not only causes a cost increase, but also has a weak impact durability due to the use of a glass tube, so it is easy to be damaged and requires careful handling. It is harmful to the environment, the service life is also about 50,000 hours, there is a disadvantage that it is rather short to apply as a permanent filter, there is a problem that requires a lot of power consumption.
