Description

Air purification filter{FILTER FOR AIR PURIFIER}

The present invention relates to an air purifying filter, and more specifically, to an air purifying filter capable of uniformly and stably fixing a filter material for air purification to a filter body.

In general, an air conditioner is a device that maintains a comfortable space by controlling the temperature, humidity, and airflow distribution in a certain space suitable for human activity while removing foreign substances in the air. The filter used in these air conditioners filters or deodorizes odorous components, fine dust, bacteria, etc. (hereinafter referred to as 'foreign substances') in the air. A filter material such as activated carbon or zeolite, which has excellent adsorption capacity for foreign substances, is attached to the filter core. It consists of a filled air filter.

Conventional prior art related to air filters includes Patent Publication No. 10-1044655 (registered on June 21, 2011) titled “Air cleaning filter manufacturing method using activated carbon and air cleaning filter manufactured thereby” (hereinafter referred to as ‘Prior Art 1’) )" has been disclosed.

The conventional air purifying filter according to prior art 1 forms a filter body with a honeycomb-shaped compartment structure. After filling the compartments of the filter body with activated carbon, the front and back of the filter body are covered with a mesh net to contain the activated carbon. It is manufactured with a structure that prevents breakaway.

However, conventional air cleaning filters require separate components such as a first mesh and a second mesh to prevent the activated carbon charged in the compartment from escaping, so complex processes to prepare such separate components are essential. This causes manufacturing difficulties, so there is a problem that it takes a lot of time and cost to manufacture it.

In addition, in conventional air purifying filters, air cannot flow smoothly because the first mesh and second mesh, which are provided to prevent activated carbon from escaping, impede the flow of air, so foreign substances in the air passing through them are sufficiently filtered. There was a problem that couldn't be done.

Moreover, in order to improve filtration and deodorization rates, conventional air purifying filters are structured to completely fill the compartment with activated carbon or fill it above a certain amount. When the activated carbon is fully filled, the space size of the compartment containing the activated carbon is minimized, thereby minimizing the air purification rate. There was a problem in that the performance of the filter itself deteriorated due to difficulty in passing and poor air circulation.

In addition, if the activated carbon is not completely filled and the compartment is filled beyond a certain amount, the activated carbon contained in the compartment remains fluid inside the compartment. Therefore, when the filter body is mounted on an air conditioner, it moves downward by gravity, leaving the upper part of the compartment empty. There was a problem that the filtration and deodorization efficiency for certain sections was reduced as space was provided.

In particular, according to the structure in which the filter body is usually installed, when the filter body is installed perpendicular to the ground, the activated carbon is concentrated in the lower part of the compartment, and a certain space in the upper part is provided as an open hole with no activated carbon at all. There was a problem in that a non-filtration area, which is a surplus space where filtration and deodorization does not occur, is created when air passes through.

In other words, if a small amount of activated carbon is filled inside the compartment, the size of the non-filtration area in the upper part of the hole is large, and if a large amount of activated carbon is filled, pressure loss occurs due to the dense space, so the amount of activated carbon filled in the compartment is large. There was a problem that filter performance deteriorated regardless of whether the amount was small or large.

In addition, in the conventional air purifying filter, even if the filter body is installed horizontally, the activated carbon is concentrated toward the opening of the compartment, resulting in a structure similar to a fully charged state of activated carbon, which still causes the problem of filter performance deterioration due to the dense space. There was a problem.

To solve this problem, the present applicant has disclosed “porous filter (hereinafter referred to as ‘prior art 2’)” in Patent Registration No. 10-2011476 (registered on August 9, 2019).

The conventional porous filter according to Prior Art 2 includes a porous plate with a plurality of holes, and has a structure that prevents the filter agent from leaving the hole by adhesively fixing the filter agent, which is activated carbon, through a fixing means provided on the inner peripheral surface of the hole. It is provided as.

Accordingly, the conventional porous filter can fix the filtering agent without mesh members attached to both sides of the porous plate, and has the advantage of cost reduction and smooth air flow due to the removal of the mesh member.

In addition, the conventional porous filter has holes in a circular or oval shape, so that the adhesive, which is a fixing means, can be applied evenly by eliminating corners on the inner circumferential surface, so that the filter medium can be stably fixed to the inner circumferential surface of the hole, and has an attachment structure on the inner circumferential surface. A ventilable area was formed on the inside of the furnace hole, and a separate vent was formed adjacent to the outside of the hole to ensure ventilation.

However, in the conventional porous filter, the filter is attached and fixed only to the inner circumferential surface of the circular hole, so when the size of the hole increases, the filter provided on the inner circumferential surface is placed at a considerable distance from the center of the hole (i.e., the filter is not present). There was a problem that the actual filter efficiency was reduced as the contact area with the passing air (the size of the filtered area increased) decreased.

In addition, the conventional porous filter provides a structure that improves ventilation by forming a ventilation hole for air flow between adjacent holes due to the circular cross-section. However, since the filter cannot be inserted into the ventilation hole, the ventilation hole is required. There was a problem that filtration and deodorization of the passing air was limited. In the end, the conventional porous filter provides a structure with improved breathability, but it does not completely solve the problems of the non-filtration area and the deterioration of the filter performance of the prior art 1, and there are still inherent problems.

Republic of Korea Patent No. 10-1044655 (registered on June 21, 2011) Republic of Korea Patent No. 10-2011476 (registered on August 9, 2019)

The purpose of the present invention is to uniformly and easily fill the filter body with the filter material, prevent the filter material from being tilted even if the filter body is tilted, and improve air flow and filtration amount. The aim is to provide a curved air purification filter with improved filtration efficiency while improving the reliability of the product by making it uniform.

In addition, the purpose of the present invention is to provide an air resistance structure that minimizes pressure loss and ensures ventilation by providing air passages while generating appropriate air flow, but does not cover non-filtration areas such as dead zones that do not contain filter media. The goal is to provide an air purification filter that can prevent air pollution from occurring.

Additionally, an object of the present invention is to provide an air purifying filter that can reduce the total amount of filter media used in the filter and reinforce the rigidity of the main body.

The air purifying filter of the present invention for achieving the above-described object includes a housing having a plurality of compartments for the passage of air, a filter material accommodated inside each compartment, and a plurality of filters integrally provided in the housing to form each space of the compartment. It includes a main part of the main part, a plurality of auxiliary fixing parts installed in the main part and in contact with the filter medium inside the compartment, and fixing means for fixing the filter medium to the main part and the auxiliary fixing part.

Here, the fixing means includes an adhesive member provided on the surface of the main part or the auxiliary fixing part to attach and fix the filter material.

And, the auxiliary fixing part divides the internal space of the compartment into at least two or more chambers.

Additionally, the main part includes at least three side walls that form the compartment into a polygonal space, and the auxiliary fixing part includes a plurality of partition members connecting the side walls.

In addition, the side wall includes first to sixth walls that form the compartment into a hexagonal space, and the partition member includes a first pillar and a third wall that protrude toward the center of the compartment from the surface of the first or second wall. a second pillar that protrudes toward the center of the compartment from the face of the wall or the fourth wall and is connected to the first pillar at a predetermined angle, and a first pillar that protrudes towards the center of the compartment from the face of the fifth or sixth wall and It includes a third pillar connected to the second pillar at a predetermined angle.

Moreover, the partition member is formed in a rectangular or circular bar shape and is formed to have a thickness smaller than the height of the side wall.

Meanwhile, the partition member is formed in the shape of a mesh-shaped plate and is formed to have a height shorter than the height of the side wall.

In addition, the fixing means further includes a groove formed to be recessed in a groove shape on the surface of the main part or the auxiliary fixing part and partially receiving the adhesive member or filter material.

Additionally, the groove includes a plurality of grooves formed along the width or length direction on the surface of the main part and spaced apart at predetermined intervals, and a plurality of dimples formed to be recessed in the surface of the auxiliary fixing part.

Moreover, the fixing means further includes an inclined surface formed to be inclined toward the groove on the surface of the main or auxiliary fixing part.

In addition, the fixing means further includes a plurality of hook protrusions that are formed to protrude adjacent to the groove on the surface of the side wall or partition member and are caught on the surface of the filter medium.

Meanwhile, according to another embodiment of the present invention, the partition member of the air purifying filter includes a first support part extending from one of the side walls, and a second support part extending from another one of the side walls and connected to the end of the first support part. 2 Includes support parts.

Here, the partition member divides the chamber into two spaces with the same size by coaxially connecting each end of the first support part and the second support part.

On the other hand, the partition member is connected so that each end of the first support part and the second support part forms a predetermined angle to partition the chamber into two spaces with different sizes.

On the other hand, the partition member is connected so that each end of the first support part and the second support part intersect at a predetermined angle and penetrate each other, thereby partitioning the chamber into four partition parts having the same size or different sizes.

According to the air purifying filter according to the present invention as described above, the filter medium is attached and fixed to the surface, so it is possible to prevent the filter medium from leaving even without using a separately configured member such as a mesh. In particular, in the air purifying filter according to this embodiment, the filter material is fixed to the main part and the auxiliary fixing part by fixing means, so that the filter material can be uniformly and easily filled and fixed in the internal space of each compartment.

In addition, the air purification filter according to this embodiment has an attached structure and provides a filter material inside the compartment, providing a fixed structure to prevent the filter material contained in the filter from flowing within the compartment, so even if the filter body is tilted, the filter material is maintained inside the compartment. It can prevent tipping, providing uniform filtration efficiency and improving product reliability.

In this way, the air purifying filter according to the present invention can purify the air passing through the compartment by the filter medium included in the housing. At this time, in the present invention, as the compartments are formed in a polygonal cross-sectional shape, it is possible to prevent non-filtration areas from occurring between adjacent compartments compared to the existing structure with a circular cross-sectional shape.

Moreover, the air purifying filter of the present invention can secure the rigidity of the main body frame by playing a supporting role for the compartment by means of an auxiliary fixing part disposed across the interior of the compartment, and the separation structure of the filter media through the auxiliary fixing part allows for , filtration efficiency can be increased by equalizing air flow and filtration amount.

Therefore, the air purifying filter of the present invention, unlike existing filters with a densely packed structure, can improve filtration efficiency while ensuring breathability. In particular, the attachment area to the filter material is expanded so that the filter material is not placed only on the surface of the compartment. As the filter material is attached to the surface of the auxiliary fixture extending to the inner center, the filtration efficiency of the filter material can be improved by increasing the area in contact with passing air.

In addition, the air purifying filter according to the present invention forms a separate vent by a bent portion according to the shape of the compartment, thereby allowing air to pass through the vent provided adjacent to the filter material fixed on the inside, thereby lowering the pressure loss of the filter material. It is possible to induce filtration to occur simultaneously, thereby improving filtration efficiency by reducing the non-filtration area.

In addition, the air purifying filter of the present invention has an attached structure, which has the advantage of reducing costs because it can reduce the total amount of filter media used. In particular, the air purifying filter of the present invention provides an air resistance structure by the main and auxiliary fixing parts while reducing the amount of filter media used, but ensures breathability, which is advantageous in terms of pressure loss and in terms of deodorization efficiency compared to the total amount. has

In addition, the air purifying filter of the present invention can secure the filter material more stably through the grooves, thereby preventing the filter material from coming off.

The advantages and features of the present invention and methods for achieving them will become clear by referring to the embodiments described in detail below along with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and will be implemented in various different forms.

Hereinafter, the technical features of the present invention will be described in detail with reference to the attached drawings.

Figure 2 is a plan view schematically showing an air purification filter according to an embodiment of the present invention. Figure 3 is a partial enlarged view of a portion of Figure 1. Figure 4 is a perspective view schematically showing a portion of a compartment of an air purification filter according to an embodiment of the present invention. Figure 5 is a cross-sectional view showing a main part of Figure 4.

First, the air purifying filter of the present invention may include a housing 10, a filter medium 20, a main part 12, an auxiliary fixing part 30, and a fixing means 40, as shown in FIGS. 1 to 3. You can.

The housing 10 may be formed in a frame shape with a predetermined thickness in the height direction. That is, the housing 10 is a part that is detachably installed in an air conditioner, etc., and the overall exterior may be formed in a polygonal shape such as a square or triangle, or a circular or oval frame corresponding to the installation space, and the outer circumference may be An outer wall (not shown) of a predetermined thickness may be formed along the side to have a reinforcing structure, or the outer perimeter may be cut open.

This housing 10 may have a plurality of compartments 11 provided in the form of holes for the passage of air on the inside.

The compartment 11 may be formed as a space provided in the form of a plurality of holes continuously arranged in the housing 10. The compartment 11 is provided in a shape in which both sides are open in the height direction of the housing 10 to allow air to pass through, and its cross-sectional shape may be polygonal.

For example, the compartment 11 may be formed in a hexagonal cross-sectional shape. At this time, in FIGS. 1 and 2, for convenience of explanation, the compartment 11 of the housing 10 is shown as having a hexagonal cross-sectional shape, but it is not necessarily limited to this, and the compartment 11 may have a triangle, square, pentagon, It can be implemented in various polygonal cross-sectional shapes, such as hexagonal or diamond-shaped, according to various embodiments (see FIGS. 6 to 9).

Here, if the compartment 11 is formed in a circular cross-sectional shape, a gap may be created between the compartment 11 and the other adjacent compartment 11, so fluid may pass through the gap, so it is a structure in which a gap is not created. It is desirable to have a polygonal cross-sectional shape. And, according to an embodiment of the present invention, the compartment 11 provided in a hexagonal shape can provide a more stable arrangement of the partition member 30, which will be described later, compared to other shapes.

Accordingly, the housing 10 can smoothly pass air through the compartment 11 formed on the inside. Although not shown, a breathable member (not shown) such as a mesh net may be provided on the front and rear surfaces of the housing 10 to protect the interior and prevent components from leaving. This compartment 11 can accommodate the filter medium 20 therein.

The filter medium 20 may be made of common materials using physical adsorption, for example, activated carbon, silica gel, activated clay, or zeolite. In the present invention, as an example, it may be composed of activated carbon.

This filter medium 20 is accommodated inside the compartment 11 as shown in FIGS. 1 to 3 and can adsorb foreign substances contained in the air. That is, the filter of the present invention can filter the air passing through the compartment 11 of the housing 10 by the filter medium 20, and in particular, can filter or deodorize odorous components, fine dust, bacteria, etc. in the air. .

The main government may be formed integrally with the housing. These main units may be provided to form each space of the compartment 11. The main part may be composed of, for example, a plurality of side walls 12 formed from the walls of each compartment 11. The side wall 12 may be disposed along the perimeter of the compartment 11 to provide each compartment 11 as an individual space. In addition, the filter medium 20 can be fixed to the surface of the side wall 12 through fixing means 40, which will be described later.

Auxiliary fixing parts may be provided inside each compartment (11). For this purpose, the auxiliary fixing unit may be installed in the main fixing unit. This auxiliary fixing part can divide the space of the compartment 11 into at least one chamber 111, 112, and 113. A plurality of chambers (111, 112, 113) are included as part of the compartment (11). At this time, the auxiliary fixing part may be provided in contact with the filter medium (20). For example, the auxiliary fixing part may be composed of a plurality of partition members 30 installed on the side wall 12, which is the main part.

Here, the partition member 30 may be installed inside each compartment 11, and the filter medium 20 accommodated inside the compartment 11 may be provided in contact with the surface. The filter medium 20 may be fixed to the surface of the partition member 30 through fixing means 40, which will be described later. In this way, the partition member 30 can arrange the filter medium 20 in the inner space of the compartment 11 while being spaced apart from the side wall 12, and is configured to support the filter medium 20.

As shown in FIG. 3, the fixing means 40 is for fixing the filter medium 20 accommodated inside the compartment 11 and connecting it to the housing 10, and the filter medium 20 is attached to the main and auxiliary fixing parts. can be fixed. That is, the fixing means 40 may be made of an adhesive that attaches and fixes the filter medium 20. Accordingly, the fixing means 40 may be configured to include an adhesive member 41 applied to the surface of the side wall 12 and the partition member 30.

The adhesive member 41 can secure the filter medium 20 to the surfaces of the housing 10 and the partition member 30 by providing adhesive force on the surfaces of the compartment 11 and the partition member 30. The adhesive member 41 may be composed of, for example, a thermosetting resin adhesive such as phenol resin, urea resin, melamine resin, polyester resin, epoxy resin, silicone resin, etc., and adhesive such as polyvinyl acetate, polyvinyl chloride, polyacrylic acid ester, etc. It may be made of a thermoplastic resin adhesive, but in the present invention, it is preferably made of a thermosetting resin adhesive.

The air purifying filter according to this embodiment configured as described above can purify the air passing through the compartment 11 by the filter medium 20 included in the housing 10.

In addition, in the air purifying filter of the present invention, since the compartments 11 are formed in a polygonal cross-sectional shape, it is possible to prevent non-filtration areas from occurring between adjacent compartments 11 compared to the existing structure with a circular cross-sectional shape. That is, in the present invention, since a bent portion is generated due to the shape of the rectangular structure, the dead zone formed between the adjacent compartments 11 by the bent portion is removed to prevent the occurrence of a non-filtration area.

Moreover, as the compartment 11 forms a separate vent (not shown) by the bent portion, air is allowed to pass through the vent provided adjacent to the filter medium 20 fixed on the inside, thereby reducing pressure loss. It can be lowered, and filtration by the filter medium 20 can be induced to occur together. That is, by forming a vent inside the compartment 11, the occurrence of unfiltered areas can be minimized and filtration efficiency is improved.

Here, the air purifying filter according to the present embodiment secures the filter material 20 to the surface of the side wall 12 provided as the main part and the partition member 30 provided as the auxiliary fixing part by the fixing means 40. , the filter medium 20 can be uniformly and easily filled and fixed in the internal space of each compartment 11.

In addition, the air purification filter according to this embodiment has an attachable structure and provides a filter medium 20 in the compartment 11, and has a fixed structure so that the filter medium 20 included in the filter does not flow within the compartment 11. Therefore, even if the filter body is tilted, it is possible to prevent the filter medium 20 from tilting, thereby providing uniform filtration efficiency and improving product reliability.

At this time, the air purifying filter of the present invention can secure the rigidity of the main body frame by supporting the compartment 11 by the partition member 30 disposed across the interior of the compartment 11, and the partition member ( Due to the spaced structure of the filter medium 20 through 30), the air flow and filtration amount can be made uniform and filtration efficiency can be increased.

In this way, the present invention, unlike existing filters with a densely packed structure, can improve filtration efficiency while ensuring breathability, and in particular, expands the attachment area to the filter medium (20) to only cover the surface of the compartment (11). As the filter medium 20 is provided on the surface of the partition member 30 that extends to the inner center without 20), the area in contact with passing air is increased, thereby improving the filtration efficiency of the filter medium 20. You can.

In addition, the air purifying filter of the present invention has the advantage of reducing costs because it can reduce the total amount of filter media 20 used.

In particular, the air purifying filter of the present invention provides an air resistance structure by the side wall 12 and the partition member 30 while reducing the amount of filter media 20 used, and provides a structure advantageous for pressure loss by ensuring breathability. You can do it. This will be explained in detail through examples below.

Meanwhile, referring again to FIGS. 1 to 3, the partition member 30 may divide the internal space of the compartment 11 into at least two chambers 111, 112, and 113. That is, the plurality of partition members 30 may be installed to cross the internal space of the compartment 11 to divide the space of the compartment 11, and the compartment 11 may be divided into a plurality of chambers 111, 112, 113) to form a division. The chambers 111, 112, and 113 may each be provided as spaces smaller than the size of the compartment 11. At this time, the number of chambers may vary depending on the cross-sectional shape of the compartment 11 and the number of partition members 30.

Since this partition member 30 is divided into a plurality of chambers in which the cross-sectional area of the compartment 11 through which air passes is reduced, it is possible to induce air to pass through the space of the chamber smaller than the compartment 11. .

For example, the partition member 30 may be provided to partition the internal space of the compartment 11 into three chambers 111, 112, and 113, as shown in the drawing. For this purpose, in this embodiment, the main part may be composed of a side wall 12 including the first wall 121 to the sixth wall 126 forming the compartment 11 as a hexagonal space, and a partition member ( 30) may include first to third pillars 31 to 33 connected to these side walls. The compartment 11 may be divided into a first chamber 111 to a third chamber 113 by the partition member 30.

The first pillar 31 constituting the partition member 30 is installed upright on the inner surface of the first wall 121, and the second pillar 32 is installed upright on the inner surface of the third wall 123. And the third pillar 33 may be installed upright on the inner surface of the fifth wall 125. The space of the compartment 11 defined between the first pillar 31 and the second pillar 32 is formed as the first chamber 111, and the space between the second pillar 32 and the third pillar 33 is formed as the first chamber 111. The space of the compartment 11 partitioned between the third pillar 33 and the first pillar 31 is formed as the second chamber 112, and the space of the compartment 11 partitioned between the third pillar 33 and the first pillar 31 is formed as the third chamber 113. ) can be formed.

In addition, each of the pillars 31, 32, and 33 of the partition member 30 may be formed as a rod-shaped member with a diameter smaller than the height direction length of the side wall 12, and the end sides may be connected to each other. Accordingly, the partition member 30 may be composed of an approximately “Y” shaped square pipe or a rod-shaped member. That is, the partition member 30 has each pillar extending from the side wall to form a contact point inside the compartment 11, and provides a predetermined air resistance structure to form a constant vortex for the circulating air flow, thereby maintaining the air flow surface. has an advantage in

At this time, the partition member 30 may be provided as a separate member in which the first to third pillars 31 to 33 are respectively installed inside the compartment 11 and the ends are coupled to each other, but the compartment 11 ) It is explained as being composed of a single body that is integrally connected to. For example, the partition member 30 may be provided integrally with the housing 10 through an injection or press molding process. In contrast, the partition member 30 may be processed as a separate member and fixed to the compartment 11 of the housing 10 through an adhesive or fitting method or a fastening structure.

In addition, as the adhesive member 41 is applied to the circumferential surface of each pillar 31, 32, and 33, the filter medium 20 can be fixed to the surface. Accordingly, the filter medium 20 can be distributed inside the compartment 11, that is, on the central side.

In this way, the partition member 30 divides the internal space of the compartment 11 into a plurality of chambers 111, 112, and 113, thereby reducing the space size of the compartment 11 through which air passes and creating a resistance structure to air passage. By forming chambers 111, 112, and 113, which are spaces of a certain size, between the side wall 12 and the partition member 30, a free space for air to pass can be provided, and a filter material is provided on the circumferential surface. Since (20) is attached, the contact area with the filter medium (20) can be increased.

On the other hand, considering the case where the size of the compartment itself is simply reduced, unlike the chamber-type structure of the present invention, when the size of the compartment is formed small, the space itself where filter media of different lengths and sizes but of a predetermined size are accommodated As it becomes narrow, there is a problem of clogging the space inside the compartment, and the relatively small size of the compartment is provided, so the air passage space is formed at tight intervals, similar to the existing fully filled structure, due to the filter media densely packed in the internal space. Accordingly, it is still not possible to solve the conventional problem. In addition, if the size of the compartment is simply small, the air flow is restricted due to the multiple compartment walls that exist along the air passage path, resulting in increased pressure loss and reduced filtration efficiency.

However, the air purifying filter according to an embodiment of the present invention has a bar-shaped partition member 30 in the form of a square or cylindrical tube on which the filter medium 20 can be attached to the peripheral surface, not in the form of a partition, across the side wall 12. It is provided in a structure in which a plurality of chambers 111, 112, and 113 are arranged inside the compartment 11.

Accordingly, the air purifying filter of the present invention differs from simply forming the compartment 11 itself to a small size, and installs a partition member 30 inside the compartment 11, but filters the filter material 20 through the partition member 30. By providing a support structure, the attachment area of the filter medium 20 can be increased and the rigidity of the frame can be strengthened, and the spaced structure between the filter medium 20 through the partition member 30 ensures uniform air flow and filtration amount. This can increase filtration efficiency.

In particular, the present invention divides the space where the filter medium 20 is accommodated into chambers 111, 112, and 113 smaller than the compartment 11, so that the structure of the filter medium 20, which is attached and fixed on the surface of the frame, occurs. It is possible to reduce the size of the dead zone, and provide a predetermined air resistance structure for the partition member 30 disposed across the interior of the compartment 11, while at the same time providing a filter material 20 provided around the partition member 30. ) can induce filtration. In other words, it has the advantage of improving filtration efficiency while minimizing pressure loss due to air passage.

In the end, the air purifying filter according to an embodiment of the present invention holds the filter medium 20 in the compartment ( Since it can be placed in the internal space of 11), the dead zone can be reduced and the area in contact between the filter medium 20 and air can be increased.

Typically, filters installed in air conditioning equipment or air conditioning performance measurement equipment have air flowing inward due to resistance caused by the filter medium 20 attached to the compartment 11. And, the air flows outward due to resistance caused by the filter medium 20 attached to the partition member 30. Ultimately, as a plurality of chambers 111, 112, and 113 are formed inside one compartment 11, the resistance is increased by the filter medium 20 disposed on the inner surface of each chamber 111, 112, and 113. As this occurs, the air has a flow toward the inside. Accordingly, the air purifying filter of the present invention reduces pressure loss and maximizes the contact area where air comes into contact with the filter medium 20.

Here, the pillars 31, 32, and 33 of the partition member 30 may be formed to have a diameter D2 smaller than the height D1 of the side wall 12, and the chamber 111 forming the compartment 11 , 112, 113), it is desirable to have a thickness that does not make the space very narrow.

For example, the filter medium 20 may be described as activated carbon as an example, and the approximate average size required for appropriate filtration efficiency of the filter medium 20 used is about 3 mm in length and about 2 mm in diameter and thickness. It can be provided, and at this time, thin and long extruded activated carbon is usually cut into arbitrary sizes and used. The size of the filter medium 20 is approximately 1 to 7 mm in length and 1 to 3 mm in diameter and thickness. can be used.

On the other hand, if the amount of filter media 20 filled in the filter housing 10 is small, it is difficult to expect an increase in filtration effect, and the filtration effect increases as the total amount of filter media filled in the receiving space of the main body increases. Not only that, but the pressure loss increases as the filter is used, which may result in a decrease in filtration efficiency.

Accordingly, the height value of the housing 10, which forms the main frame of the filter, can be set to a size of approximately 10 mm to 45 mm in terms of increasing the deodorization rate and relatively low pressure loss, that is, optimizing filtration efficiency.

For example, the furrow groove 421 may be formed as a long groove disposed in the longitudinal direction of the short side of the side wall 12 along the height direction of the main body frame of the housing 10, as shown in Figure 4, and a plurality of long grooves are formed on the side wall. It can be arranged and spaced apart in the longitudinal direction of the long side of (12). That is, the furrow groove 421 may be formed on the inner surface of each side wall 12.

The dimple 422 may be provided as a groove that is recessed in the surface of the partition member 30. These dimples 422 may be composed of a plurality of dimples 422 and may be arranged on the surface of the partition member 30 while being spaced apart at predetermined intervals. For example, the dimples 422 may be formed as a plurality of hemispherical grooves formed on the peripheral surface of the partition member 30, as shown in FIG. 4.

The adhesive member 41 can be accommodated in these furrow grooves 421 and dimples 422, and the filter material 20 can be partially inserted and fixed therein. Accordingly, the air purifying filter of the present invention can effectively fix the filter medium (20).

At this time, the groove 42 may be provided with an inclined surface 42a that is inclined on the surface of the side wall 12, as shown in FIG. 5. For example, the inclined surface 42a may be formed to be inclined toward the furrow groove 421. This inclined surface (42a) guides the entry of the filter medium (20) partially accommodated in the groove groove (421), and is arranged to contact the surface of the inserted filter medium (20) to support the filter medium (20). Accordingly, the groove 42 improves the attachment area so that more filter media 20 can be accommodated, and the filter media 20 can be stably fixed.

In addition, although not shown, the fixing means 40 may further include a plurality of hook protrusions (not shown), and the hook protrusions are formed against the groove 42 on the surface of the side wall 12 or the partition member 30. It may be formed to protrude adjacently and be caught on the surface of the filter medium 20. Accordingly, the present invention can fix the filter medium 20 more stably.
