Referring to FIG. 1, the air cleaner 100 includes a body 110, a catcher 20, and an air purifier 30 that form an external shape. The body 110 includes a frame 110a having an air flow path therein, a top cover 110b having an air inlet 122 and a bottom cover 110 having an air outlet 132 formed therein .

2 and 3, the catch 20 may be disposed adjacent to the air inlet 122 within the body 110. As shown in FIG. The catching part 20 may include a mineral oil unit 210 for attracting insects and a collecting frame 250 disposed at the rear end of the mineral oilink unit 210. [ The light oil emitter 210 may include a support structure 211, a first light emitting diode portion 212, and a reflective structure 213.

The support structure 211 may be fixed so that the first light emitting diode part 212 and the reflective structure 213 are disposed at predetermined positions inside the body part 110. The first light emitting diode part 212 and the reflective structure 213 may be spaced apart from each other. The support structure 211 can be fixed to the top cover part 110b.

The first light emitting diode unit 212 may be disposed on the support structure 211 to emit insect attracting light toward the interior of the body 110. Specifically, the first light emitting diode unit 212 may provide light having a wavelength of at least one of ultraviolet rays, visible rays, and infrared rays. As an example, in case of ultraviolet rays, the first light emitting diode part 212 may provide ultraviolet rays having a wavelength band of about 200 to 400 nm.

Regarding the wavelength with which the insect is attracted, it is reported that, for example, flies and butterflies prefer light of a wavelength of about 340 nm or about 575 nm, and moths and mosquitoes prefer light of a wavelength of about 366 nm . It has also been reported that, in the case of other common pests, relatively light of wavelengths of about 340 nm to 380 nm is preferred. As another example, Korean Patent Publication No. 2013-0049475 or Korean Published Patent Application No. 2014-0010493 discloses that the induction activity of insects by white, yellow, red, green, and blue light is related to the wavelength of the visible light region in which insects are attracted . In the present embodiment, not only the above-described concrete examples are applied, but also various other wavelengths of light not described in the above-mentioned examples can be applied as long as conditions that can attract the insect vision can be satisfied.

The first light emitting diode unit 212 may include a printed circuit board 212a and a light emitting diode 212b disposed on the printed circuit board 212a. In this specification, the light emitting diode 212b can be used as a concept including a light emitting diode chip or a light emitting diode package. The light emitting diode chip may be mounted on a printed circuit board 212a in the form of a chip on board (COB). The light emitting diode package may be formed by various known bonding methods such as a lead frame, a solder ball, And can be mounted on the printed circuit board 212a.

A reflective structure 213 may be disposed under the first light emitting diode unit 212. The reflective structure 213 may reflect light emitted from the first light emitting diode part 212 and emit the light to the outside of the body part 110. The reflective structure 213 may be made of a material such as silver, aluminum, or a silver or aluminum film coated on a predetermined structure. Although the reflective structure 213 is formed so as to have a predetermined curvature toward the first light emitting diode portion 212, the reflective structure 213 is not necessarily limited to this, but may be formed to have a plate shape or a curvature opposite to that shown There are many variations such as.

The reflective structure 213 may be disposed inside the body 110, away from the first light emitting diode unit 212. The reflective structure 213 may reflect light emitted from the first light emitting diode part 212 and provide light to the outside of the body part 110 through the air inlet 122. In the figure, the reflective structure 213 may have a concave shape with a center of curvature in the direction of the first light emitting diode part 212. However, the present invention is not limited thereto. As shown in FIG. 4 (a), the reflective structure 213a may have a convex shape having a center of curvature in a direction opposite to the first light emitting diode portion 212. In some other embodiments, various shapes of curved or uneven patterns may be disposed on one surface of the reflective structure 213 facing the first light emitting diode 212 to scatter incident light. As an example, as shown in FIGS. 4B and 4C, one surface of the reflective structures 213b and 213c may have a stepped bent pattern. Thus, by providing the grooved or concave-convex pattern, the reflection structure 213 can cause reflection as well as scattering. As a result, the visual attracting effect on the insects located outside the body 110 can be improved. Although not necessarily limited to a specific theory, the inventors have experimentally confirmed that the visual attracting effect of insects is relatively large by the light reflected or scattered by the reflecting structure rather than the light directly irradiated from the light emitting diode. The reflective structures 213 213a 213b 213c may be fixed to the printed circuit board 212a or the support structure 211 by the support members 214. [

A blowing fan 410 may be disposed below the mineral oil unit 210. The blowing fan 410 may generate an air circulation from the air inlet 122 to the air outlet 132. [ The blowing fan 410 may also suck the insect entrained around the air inlet 122 into the body 110 and move the insect to the collecting mold 250. Although the blowing fan 410 is shown between the mineral oil unit 210 of the catching part 20 and the collecting mold 250 in the figure, the present invention is not limited thereto. The blowing fan 410 may be an air purifier 30) and the air outlet 132. [0050]

The collecting mold 250 may be configured to be detachable through the side wall of the frame portion 110a. The collecting mold 250 can collect the insects introduced into the body 110 by the mineral oil unit 210 and the blowing fan 250.

As shown in Fig. 2, the collecting mold 250 may include a lower screening net 254a disposed on the lower surface of the body 254 and the body 254 and having a lattice structure of sufficient thickness to capture insects. have. Therefore, the insect moving along the air flow path inside the body 110 can be captured by the lower screening net 254a. When a certain amount of insects are collected, an upper screening net 254b is inserted into the upper part of the body 254 to prevent the trapped insects from separating from the collecting frame 250. The attracting guide portion 254c attached to the body 254 is then pulled so that the collecting frame 250 can be attached and detached through the side wall of the frame portion 110a in a sliding manner.

In some embodiments, the insecticide may be provided to the sidewall of the body 254 or the insect nets 254a. As a result, the insects trapped in the collecting mold 250 can be killed using the insecticide. In some embodiments, an adhesive material may be applied to the lower screening net 254a. As a result, the insect in contact with the lower screening net 254a can be adhered and captured. In this case, the excessive adhesive material is controlled not to be applied to the lower screening net 254a so that the adhesive does not interfere with the flow of air.

2 and 3, the air purifier 30 is disposed at the rear end of the catcher 20. The air purifying unit 30 includes a second light emitting diode unit 310 disposed along the air flow path inside the body 110 and a filter unit 320 disposed adjacent to the second light emitting diode unit 310 . The filter unit 320 may include a photocatalytic filter 321, a carbon filter 322, and a collecting filter 323 in this order adjacent to the second light emitting diode unit 310.

The second light emitting diode unit 310 may include a printed circuit board 313a disposed on the first surface of the support panel 312 and a sterilizing light emitting diode 314a mounted on the printed circuit board 313a . At this time, the support panel 312 may be manufactured with a passage for air flow. The sterilizing light emitting diode 314a may be arranged to face the catching part 20. The sterilizing light emitting diode 314a may include a light emitting diode chip or a light emitting diode package that emits ultraviolet light having a wavelength of about 200 to 300 nm. The sterilizing light emitting diode 314a can sterilize the collecting mold 250 by irradiating the collecting mold 250 of the collecting part 20 with ultraviolet light having the above-mentioned wavelength.

The second light emitting diode unit 310 may include a printed circuit board 313b disposed on the second side of the support panel 312 and a light emitting diode 314b mounted on the printed circuit board 313b . The light emitting diode may include at least one of a light emitting diode for photocatalyst and a light emitting diode for sterilization. The light emitting diode for photocatalysis may include a light emitting diode chip or a light emitting diode package that emits ultraviolet light having a wavelength of about 200 to 400 nm. The sterilizing light emitting diode may include a light emitting diode chip or a light emitting diode package that emits ultraviolet light having a wavelength of about 200 to 300 nm.

The light emitting diode for the photocatalyst may react with the photocatalytic filter 321. The photocatalytic filter 321 may comprise a material that provides a photocatalytic reaction as a photocatalytic medium. As an example, the photocatalytic medium may include at least one of titanium oxide (TiO2), silicon oxide (SiO2), tungsten oxide (WO3), zirconium oxide (ZnO), strontium titanium oxide (SrTiO3), niobium oxide (Nb2O5) Zinc oxide (ZnO2), tin oxide (SnO2), and the like. The photocatalytic filter 321 may be formed in a layered structure including titanium oxide (TiO2). The photocatalytic filter 321 may be a photocatalyst material such as a metal foam or a porous ceramics, which is manufactured to coat the photocatalyst with a material through which air can flow, or may have a structure capable of air flow.

The photocatalytic filter 321 can perform a photocatalytic reaction with ultraviolet rays of about 200 to 400 nm emitted from the photocatalytic light emitting diode. When the ultraviolet light is absorbed in the photocatalytic medium, electrons (e) and holes (+) are generated on the surface and move to the surface of the photocatalyst. At this time, electrons and holes generated in the photocatalytic medium are redox- The material can be removed. The electrons generated on the surface of the photocatalyst are reacted with oxygen on the surface of the photocatalyst to form a superoxide anion (? O 2 -). The holes are reacted with a hydroxyl group (-OH) To produce hydroxyl radicals (? OH). At this time, the generated hydroxyl radical can oxidatively decompose organic pollutants in the air. Thus, the pollutant and odorous substances in the air introduced into the air purifier can be decomposed and converted into water and carbon dioxide. In addition, the hydroxyl radical may act as a strong oxidizing agent to perform a sterilizing action. In this manner, the photocatalytic light emitting diode and the photocatalytic filter 321 cooperate with each other to perform a deodorizing and sterilizing action on the flowing air.

The sterilizing light emitting diode can directly sterilize bacteria in the air flowing inside the body 110 or sterilize the bacteria trapped in the trapping filter 323. The collecting filter 323 may have fine pores so that bacteria can not easily pass through. The trapping filter 323 may have a shape in which the filter material is folded with respect to the air flow direction so as to increase the surface area to increase the trapping amount per unit area. Bacteria collected in the trapping filter 323 can be sterilized by about 200 to 300 nm ultraviolet rays emitted from the sterilizing ultraviolet light emitting diode. The trapping filter 323 can increase the sterilizing efficiency of the sterilizing ultraviolet light emitting diode by increasing the time for bacteria in the air to be exposed to the sterilizing ultraviolet light. In some embodiments, the collection filter 323 may comprise a sterilizing agent. The bactericide may further increase the bactericidal efficiency.

The filter unit 320 may function in cooperation with the second light emitting diode unit 310 to purify the flowing air as described above. However, according to some embodiments, a carbon filter 322 may be additionally disposed, wherein the carbon filter 322 includes activated carbon and a catalyst to filter organic chemicals in the air. Thereby, a deodorizing action can be performed on the flowing air. In the drawing, the carbon filter 322 is disposed between the photocatalytic filter 321 and the collecting filter 323, but is not limited thereto. The carbon filter 322 may be disposed at the rear end of the trapping filter 323 in order to increase the irradiation efficiency of the sterilizing ultraviolet ray to the trapping filter 323. [ Further, although not shown, the filter unit 130 may further include various functional filters. As an example, the functional filter may include a Hepa filter, a deodorizing filter, an antibacterial filter, an allergen filter, and the like.

A bottom cover 110c having an air outlet 132 may be disposed at a rear end of the filter unit 320. [ The air purified by the air purifier 30 may be discharged to the outside of the body 110 through the air outlet 132.

That is, it is possible to inhibit the growth of bacteria by the insects trapped in the collection frame. The air purifier may perform a sterilization and deodorizing action on the air flowing along the flow path by using a sterilizing light emitting diode and a photocatalytic light emitting diode disposed on the opposite side of the one surface of the support pattern.
