Can be removed effectively.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the filter 100 according to the present invention is mounted inside the air cleaner 10 and includes yellow dust and fine dust contained in the indoor air, as well as toluene, formaldehyde, ammonia, sulfur oxides and nitrogen oxides. It adsorbs environmentally harmful substances and cleans the indoor air.

The air cleaner filter 100 of the present invention as described above will be described in detail.

2 is a perspective view of the filter 100 according to the present invention.

As shown in FIG. 2, the filter 100 of the present invention includes a rolled film 101, and a plurality of protrusions 102 are formed on the film 101. An incision 103 is formed.

The film 101 of the filter 100 is formed of a polymer synthetic resin such as polypropylene and polyethylene. At this time, the thickness of the film 101 is preferably molded to a thickness of 0.1 ~ 1.0mm, because if the thickness of the film 101 is less than 0.1mm there is a problem that the rigidity of the film 101 is not maintained to be.

The charged film 101 is charged by the high voltage generator so that the film 101 retains static electricity, so that fine dust is collected by electrostatic charge and fine dust.

That is, one side of the film 101 has a polarity of (+), the other side of the film 101 has a polarity of (-), and when the film 101 is wound, the (+) and (- ) Polarity is alternately stacked to generate strong static electricity. In addition, after the film 101 is charged by the high voltage generating device as described above, the non-conductive coating layer 104 is formed on the surface of the film 101 to prevent static electricity from being discharged, thereby preventing static electricity of the film 101 from being discharged. Make it exist permanently.

Since the charge of the film 101 by the high voltage generator is already known, a detailed description thereof will be omitted.

Most of the fine dust in the air has a polarity, when the fine dust is attached to the film 101 due to the traction force due to the polarity of the fine dust and the polarity of the film 101 when passing through the filter 100 having the static electricity Fine dust is filtered out.

In addition, some fine dust in the air does not have a polarity, but when such non-polar fine dust approaches the filter 100, induced static electricity is generated so that the non-polar fine dust has polarity and sticks to the film 101 and is collected.

In addition, a plurality of protrusions 102 are formed on the surface of the film 101. When the film 101 is wound to form the filter 100, the film 101 and the film (with which the protrusions 102 are wound) are formed. A gap is created between 101 to allow air to flow smoothly into the gap and to remove fine dust.

At this time, the air introduced into the filter 100 forms a vortex by the protrusion 102 to extend the flow time of the air introduced into the filter 100, thereby collecting dust more efficiently.

The surface of the protrusion 102 is formed with a cutout 103 in which a portion of the film 101 is cut in the form of a crank or a cross. By forming the cutout 103 in the protrusion as described above, by increasing the contact area between the air introduced into the filter 100 and the filter 100, dust in the air can be efficiently collected.

The filter 100 of the present invention is applied to the projections of the film 101 by applying and adhering the extract liquid and the functional liquid which is a photocatalyst mixture according to the applicant's patent No. 586924 "Method of manufacturing and processing a multipurpose natural plant extract" By forming the coating layer 105, in addition to yellow sand and fine dust, it is possible to remove environmental harmful substances such as toluene, formaldehyde, ammonia, nitrogen oxides (NOx) and sulfur oxides (SOx) contained in the air.

The extract of the above-mentioned patent No.586924 is fast extract, goji berry, tofu, medicinal herb, bokbunja strawberry, ogapi, schisandra, violet, camphor ginseng, balm, thistle, cheonma, nectar, dandelion herb, longan, haesong, 칡, pear scent, sewage, yellow Dry, powder, mix, and dry 37 ingredients of cinnamon, super stone, golden, thyme, bellflower, deodeok, mugwort, health, donkey, Chinese quince, hyssop, sage, red ginseng, venom, three hundreds, white ginseng, and ginseng The extract is collected by passing through a cooler.

Application and fixation of the functional solution of 30-70% by weight of the extract of Patent No.586924 (hereinafter referred to as "extract") and 30-70% by weight of a photocatalyst made of titanium dioxide to the projections 102 of the film 101 By removing the environmental harmful substances such as formaldehyde, ammonia, toluene, nitrogen oxides (NOx) and sulfur oxides (SOx) by the mixture, to generate far infrared rays, and to produce a filter 100 having antibacterial properties. .

The photocatalyst is widely used as an environmentally friendly material as a material for removing odors, bacteria and volatile organic compounds by using light as a catalyst. However, as the photocatalyst emits a function using light as a catalyst, there is a problem that it is difficult to exhibit the function at night or indoors where the amount of light is insufficient. Therefore, by mixing the photocatalyst and the extract liquid to form a functional liquid and applying it to the projection 102 of the filter 100, it can exhibit its function even at night without light.

In addition, the functional coating layer 105 formed by applying the functional liquid containing the extract liquid can maintain the air in the room more comfortably because the antibacterial and far-infrared rays are radiated.

The manufacturing method of the air cleaner filter of this invention as mentioned above is demonstrated in detail.

3A to 3E are cross-sectional views of the film 101 for each process of manufacturing the filter 100 for an air cleaner according to the present invention.

Press punching the film 101 of FIG. 3A charged by the high voltage generator to form a protrusion 102 on the surface of the film 101 as shown in FIG. 3B. At this time, the degree of protrusion of the protrusion 102 is preferably about 0.5 to 3.0 mm. If the degree of protrusion of the protrusion 102 is smaller than 0.5 mm, the flow resistance of air passing through the filter 100 is increased, and the protrusion is increased. This is because when the degree of protrusion of the 102 is larger than 3.0 mm, the function of the filter 100 may not be properly performed.

As described above, as shown in FIG. 3C, the protrusions 102 formed on the film 101 are cut to form a cutout 103 to crank or cross-shaped.

The protrusion forming step and the incision forming step may be simultaneously made by press working, or may be made by a separate process.

As described above, an insulator coating layer forming step of forming the insulator coating layer 104 is performed by applying an insulator material to both surfaces of the film 101 that has undergone the incision forming step as shown in FIG. 3D. The non-conductive material is to prevent the discharge of the static electricity of the charged film 101, the non-conducting material of this function can be selectively selected and used in the non-conductive material already widely commercially available in the market, so Description is omitted.

The functional liquid formed by mixing 30 to 70% by weight of the extract and 30 to 70% by weight of the photocatalyst is applied to both sides of the protrusions 102 of the film 101 which has undergone the step of forming the non-conductive coating, and dried. By performing the functional liquid coating step of fixing to form a functional coating layer 105 by.

Thereafter, the film 101 is wound around a predetermined number of times according to the design conditions of the air cleaner 10 to form a roll-shaped filter 100 and cut to a predetermined length to produce a filter for an air cleaner.
