The present invention relates to a filter assembly of an air cleaner, and more particularly, to a filter assembly of an air cleaner that exhibits an excellent effect on the removal of odor in a restaurant such as a restaurant where various odors are mixed to cause odors.

As air pollution becomes serious, air contains many harmful substances and pollutants that are harmful to the human body. If the air containing the harmful substances and pollutants is inhaled without filtering, respiratory diseases or headaches, etc. It causes the same disease and adversely affects the human body.

Therefore, the air purifier for filtering the harmful substances and dust in the air to clean the clean air has been in the spotlight from many people in recent years.

Typically, the air purifier filters out harmful substances and dust in the air through the filter. The air purifier filter system has a configuration as shown in FIG.

1 is an exploded perspective view showing a filter system of a conventional air cleaner.

As shown in FIG. 1, the air purifier includes a main body 1 having an air inlet 1a therein, a deodorizing filter 2 installed just before the air inlet 1a of the main body, and the deodorizing filter ( 2) in front of the HEPA filter (3), the medium filter (10) installed in front of the HEPA filter (3), the pretreatment filter (4) and the pretreatment filter (4) provided in front of the medium filter (10) It is composed of a filter cover (5) disposed while hiding the above-described filters from the outside.

Here, the filter system refers to the pretreatment filter 4, the medium filter 10, the hepa filter 3, and the deodorization filter 2, and the air introduced into the filter cover 5 is primarily a pretreatment filter. After passing through each filter in the order of the medium filter (10), hepa filter (3), deodorizing filter (2) through the (4) and enters the air inlet (1a).

The pretreatment filter 4 through which the introduced air passes first has a function of removing dust, pollen, etc. having relatively large particles contained in the air.

Therefore, the air primarily filtered from the pretreatment filter 4 flows back into the medium filter 10. The medium filter 10 typically removes dust of particles larger than 1 μm in a secondary manner, and the medium filter ( Air passed through 10 is introduced into the HEPA filter (3).

The High Efficiency Particulate Air (HEPA) filter 3 has a purifying power to remove a large amount of fine dust of about 0.3 μm or less, which is known to be the most harmful to the human body among dust suspended in the air, as well as contained in the air with strong adsorption power. It has a function to remove dust mites, viruses, molds, bacteria and tobacco smoke that are harmful to the human body.

In addition, the deodorization filter (2) is a composite deodorization filter impregnated with a low temperature catalyst has a strong antibacterial function, and harmful chemicals such as volatile organic compounds (VOCs), ammonia, aldehydes, tobacco smell, Adsorb and remove animal smells.

Here, the medium filter 10 may be disposed in front of the hepa filter 3 in addition to the above-described function to prevent the hepa filter 3 from being damaged from relatively large particles contained in the air. It is recommended to replace it.

FIG. 2 is a cross-sectional view of a conventional medium filter taken along the line A-A of FIG.

Referring to FIG. 2, a conventional medium filter 10 will be described. In the related art, two different members are combined to form a filter assembly (hereinafter, the same reference numeral as the medium filter). The filter assembly 10 is described. The non-woven fabric 11 that faces the air inflow direction first, and the foam member 12 is installed so that the air contacted to the rear surface of the non-woven fabric 11 is passed through the non-woven fabric 11 Is made of.

The nonwoven fabric 11 filters dust having a relatively large particle contained in the air, and the foam member 12 has a function of supporting the nonwoven fabric 11 so as to maintain a predetermined shape.

Since the nonwoven fabric 11 is composed of a soft nonwoven fabric 11 because the material is soft, it is difficult to restore the original shape after the filter is easily wrinkled or crumpled, so the foam member 12 having excellent elastic restoring force on the rear surface of the nonwoven fabric 11 is excellent. To maintain the shape as the filter assembly 10, and to restore the original shape even if it is deformed.

The foam member 12 should not only have strength enough to support the nonwoven fabric 11, but also have excellent elastic restoring force, and the resistance will be minimal when the air passing through the nonwoven fabric 11 passes. It is required to form a foam, that is, many holes are formed to implement this.

However, the conventional medium filter as described above is only equipped with a function of removing only the large particles, such a bad smell in a place where various odors and oils used in cooking, such as a food industry, are mixed with each other to cause odors. There is a problem in that the odor is not removed and passes through the filter to be discharged back to the person to create an unpleasant feeling.

In particular, when the air cleaner is operated for a long time in a bad smell, particulates that cause odor are attached to the filter at all, and the user's dissatisfaction is increased by blowing a disgusting and disgusting smell when the air cleaner is initially operated.

The present invention has been proposed to solve the above problems, the object of which is to filter the odor causing substances and oil floating in the air in a specific filter built in the air purifier ultimately air in restaurants and the like When operating the purifier, it is possible to remove not only dust but also odors.

At this time, the coupling means is characterized in that any one of double-sided tape, hot melt or silicone.

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

Figure 3 is a cross-sectional view showing a medium filter assembly of the present invention with respect to the line AA of Figure 1, Figure 4 is an exploded perspective view showing a medium filter assembly according to the invention, Figure 5 is an exploded perspective view showing an activated carbon member according to the present invention to be.

As shown in the drawings, the present invention relates to a medium filter assembly for secondarily filtering the dust of particles larger than 1 um contained in the air passing through the pretreatment filter among the plurality of filters entering the air cleaner.

The filter assembly 20 of the present invention includes a nonwoven fabric 21, a foam member 22, and an activated carbon member 25. The nonwoven fabric 21 includes dust or pollen of relatively large particles contained in air. Since it is the same configuration as the nonwoven fabric described in the prior art for filtering, further description is omitted.

On the other hand, the activated carbon member 25 is inserted between the nonwoven fabric 21 and the foam member 22, the odor contained in the air passing through the nonwoven fabric 21 is formed on the activated carbon member 25 Odor removal effect by confining and adsorbing in the porous (多 공).

For reference, the activated carbon member 25 is made of carbonaceous material of most of the constituent material, has a strong adsorptive property, and the manufacturing method is a raw material such as wood, lignite, peat, etc. as a activating agent such as zinc chloride or phosphoric acid. Treated to dry or charcoal activated by water vapor.

Activated carbon is used in the form of powder (powder) or granule (granular), and its use is mainly used to absorb gas or moisture as an adsorbent. The principle of adsorption is that gas or water vapor in numerous holes (pores) in activated carbon By attaching molecules, the odor is removed.

Here, the activated carbon member 25 is formed in a granular form having predetermined particles, and is inserted between the nonwoven fabric 21 and the foam member 22, wherein the nonwoven fabric 21 and the foam member 22 are disposed between the nonwoven fabric 21 and the foam member 22. A configuration for facilitating the insertion of the activated carbon member 25 and for preventing the granular activated carbon member 25 from being biased and positioned after the load is applied is required.

That is, the activated carbon member 25 is the nonwoven fabric 21 and the foam member 22 so that the activated carbon member 25 may be uniformly disposed evenly between the nonwoven fabric 21 and the foam member 22. It consists of a mesh member 26 having a predetermined size corresponding to the area of and the granular activated carbon 27 attached to the mesh member 26.

The mesh member 26 may not necessarily be the same as the area of the nonwoven fabric 21 or the foam member 22, and may be formed to have a somewhat smaller area. However, when the mesh member 26 has a small area, the nonwoven fabric 21 or the foam member 26 may be formed. It is preferable that the center of the nonwoven fabric 21 or the foam member 22 and the center of the mesh member 26 coincide with each other so as not to be far from the edge of the (22).

In addition, the granular activated carbon 27 attached to the mesh member 26 is preferably processed to have a size suitable for the mesh of the mesh member 26, and thus activated carbon 27 having a predetermined particle size. ) Is spread evenly attached to the mesh member (26).

On the other hand, the foam member 22 may be of various types, but as a urethane foam (hereinafter, using the same reference numerals as the foam member) to form a sponge by forming a lot of fine holes in the urethane excellent in processing and elastic force It is preferred to be configured.

The urethane foam 22 has a predetermined strength and elastic force, and is only used to support the nonwoven fabric 21 by supplementing the disadvantage that it is difficult to maintain the shape as the filter assembly 20 only by the nonwoven fabric 21. In addition, the restoring force is excellent so that even if the elastic deformation is restored to the original state without damage.

In the present invention, the activated carbon is attached to the urethane foam 22, which is very small in powder form, so that the odor is doubled together with the activated carbon member 25 to double the deodorizing effect. .

At this time, the urethane foam 22 may be directly attached to the powdered activated carbon, but by dipping the urethane foam 22 in a solution in which the activated carbon is dissolved, an immersion method for allowing the activated carbon component to penetrate the urethane foam 22 may be used. It may be.

On the other hand, the nonwoven fabric 21 and the foam member 22 is coupled means 23 so that the granular activated carbon member 25 inserted between the nonwoven fabric 21 and the foam member 22 is prevented from leaking to the outside. It is preferable to combine through.

The coupling means 23 is most preferably provided at four edges of at least one member of the nonwoven fabric 21 and the foam member 22, wherein the coupling means 23 is a double-sided tape, hotmelt , Silicon and the like.

Accordingly, when any one of the coupling means 23 is selected and installed on one or both of the nonwoven fabric 21 and the foam member 22, the nonwoven fabric 21 and the foam member 22 are coupled to each other. The granular activated carbon member 25 embedded therein does not leak to the outside.

Here, since the granular activated carbon member 25 is formed to be somewhat smaller than the nonwoven fabric 21 or the foam member 22 as described above, both sides of the granular activated carbon member 25 are formed at the edges of the nonwoven fabric 21 or the foam member 22. Even if the coupling means 23 such as a tape is installed, the non-woven fabric 21 and the foam member 22 are bonded only to each other without being attached to the activated carbon member 25.

According to the present invention as described above, by removing the dust contained in the air passing through the filter in the medium filter of the air purifier as well as the substances causing the odor largely, especially in a place where a lot of odors are mixed and coexist, such as restaurants There is a peculiar effect of doubling the removal effect.
