Description

Technical Field

[0001] The present invention relates to a filter assembly for filtering foreign matter, odor and the like in the air. Background Art

[0002] The filter assembly is used in the air purifier to remove pollutants in the air. The filter assembly may have a function of filtering specific pollutants to suit the use environment of the air purifier. For example, in order to filter specific pollutants such as dust of a specified size, specific odors, specific viruses, etc., a filter assembly with a specific function is used.

[0003] As an example of such a filter assembly, existing document 1, Korean Patent Publication No. 10-2019-0025882, discloses an air purifier for purifying air inhaled from all directions, in which a cylindrical filter assembly is used. The filter used in such a cylindrical filter assembly can usually be manufactured by stacking components with 2 to 3 functions. That is, filters with specific functions can be made concentric and overlapped on the filter assembly for use. However, in this way, even if air is inhaled from all directions, if the pollution source is on one side, only the air inhaled from that direction and passing through the filter assembly contains pollutants, and there are no pollutants in the air inhaled from other directions. Therefore, the pollutants may be concentrated only in a part of the filter of the filter assembly. Therefore, there is the inconvenience of cleaning or replacing the filter assembly even if there are more clean areas without pollutants left in the filter.

[0004] In the prior art document 2, Korean Patent Publication No. 10-2014-0146190, the filter assembly for filtering pollutants is also arranged in a cylindrical shape, and thus has the same problem as the prior art document 1.

[0005] In the existing document 3, namely Korean Publication Patent No. 10-2018-0044568, a plurality of air purification modules are used, which are combined into a cylindrical shape, and the air sucked from the outside through the center is separated and flows to each air purification module. Due to this structure, air with pollutants of the same composition will be evenly distributed and flow to each air purification module, so all air purification modules are evenly polluted, and thus all air purification modules will be replaced at the same time. Moreover, since each of these air purification modules is a filter assembly, a plurality of filter assemblies are actually used, and each air purification module needs to be replaced when replacing, and there is a problem that there is no reusable part.

[0006] In the existing document 4, namely Korean Patent Publication No. 10-2021-0026729, there are multiple filter assemblies, which are used by rotating and moving in sequence to the position where the air is sucked in. Therefore, it is not capable of purifying the air transmitted from all directions at the same time. Since one filter assembly is used and then rotated to use the filter assembly next to it, there is a problem that it is impossible to purify various pollution sources entering from other directions. Summary of the invention

[0007] Problem that the invention aims to solve

[0008] An object of the present invention is to enable a plurality of filters constituting a filter assembly to be replaced individually.

[0009] An object of the present invention is to produce a filter assembly from a plurality of separable components.

[0010] An object of the present invention is to smoothen the attachment and detachment of a filter constituting a filter assembly.

[0011] An object of the present invention is to enable selective use of a filter having a function corresponding to an adjacent pollution source in a filter assembly having a cylindrical structure.

[0012] Means used to solve problems

[0013] In order to achieve the above-mentioned object, the present invention has a plurality of filters constituting a filter assembly, and these plurality of filters can be replaced individually according to the degree of contamination.

[0014] In the filter assembly of the present invention, a plurality of filters can be detachably provided on the frame forming the skeleton. Therefore, if a specific filter is separated from the frame, the filter can be replaced, and the frame can be used permanently.

[0015] In the filter constituting the filter assembly of the present invention, a handle may be provided on one side of its edge. Therefore, the handle can easily operate the filter without reducing the area through which air passes through the filter.

[0016] Since the filter assembly of the present invention is composed of a plurality of filters, each filter can perform a different function.

[0017] The present invention may include a frame and a filter. The filter is detachably mounted on the frame and configured to filter predetermined pollutants. A plurality of filters are coupled to the frame to form a cylindrical shape.

[0018] In the frame, a first base having a first through hole and a second base having a second through hole are connected to each other by a connecting column, and a filter may be arranged between the first base and the second base.

[0019] The connecting posts may include at least two connecting posts that are spaced apart from each other at a specified angle.

[0020] The inner column locking piece may be formed to protrude with a predetermined width along one side in the width direction of the connecting column, that is, along one side of the connecting column close to the first through hole and the second through hole.

[0021] In some of the connecting columns, an outer column locking piece may be further provided at the other side of the connecting column in the width direction, that is, at a position in the connecting column corresponding to the outer sides of the first base and the second base.

[0022] In the connection column having the outer column retaining piece, the filter can be installed on or removed from the frame in a direction in which a portion of the filter corresponding to the outer column retaining piece approaches the connection column and moves away from the connection column.

[0023] A first inner stopper rib may be formed along the edge of the first through hole of the first base, a second inner stopper rib may be formed along the edge of the second through hole of the second base, a first outer stopper protrusion may be formed along the outer edge of the first base, and a second outer stopper protrusion may be formed along the outer edge of the second base.

[0024] A handle may also be provided in the filter at a position adjacent to the first decorative plate and the second decorative plate.

[0025] The present invention may include a frame and a plurality of filters, wherein the plurality of filters are detachably mounted on the frame and configured to filter predetermined pollutants.

[0026] A plurality of the filters may be mounted on the frame to form a plurality of layers.

[0027] In the frame, a first base having a first through hole, a second base having a second through hole, and a third base having a third through hole can be separated by a specified interval and connected by a connecting column, and the filter is respectively arranged between the first base and the third base and between the third base and the second base to form a cylindrical shape.

[0028] The connecting posts may include at least two connecting posts that are spaced apart from each other at a specified angle.

[0029] The inner column locking piece may be formed to protrude with a predetermined width along one side in the width direction of the connecting column, that is, a side of the connecting column close to the first through hole, the second through hole, and the third through hole.

[0030] In some of the connecting columns, an outer column locking piece may be provided at the other side of the connecting column in the width direction, that is, at a position in the connecting column corresponding to the outer sides of the first base, the second base, and the third base.

[0031] Each of the filters may have a predetermined circumferential angle so that each of the filters is mounted on the frame to form a cylindrical shape.

[0032] The circumferential angle of the filter may have any value among 180 degrees, 120 degrees, and 90 degrees.

[0033] The present invention may include at least two filters and a coupling structure for coupling the filters to each other, wherein the filters are configured to filter predetermined pollutants and form at least two cylindrical shapes.

[0034] The coupling structure may be first coupling concave-convex and second coupling concave-convex respectively formed at corresponding positions of the filters coupled to each other.

[0035] The first coupling protrusions and depressions may be in a convex shape formed protruding from any one of the filters, and the second coupling protrusions and depressions may be in a concave groove shape formed in the other one of the filters.

[0036] Effects of the Invention

[0037] The filter assembly of the present invention can have at least one or more of the following effects.

[0038] In the filter assembly of the present invention, a plurality of filters can be installed in a frame. The plurality of filters can be installed in the frame in a cylindrical shape as a whole. Therefore, each filter can be selectively replaced, so that the filter can be used more effectively.

[0039] In the filter assembly of the present invention, a plurality of filters can be separated from the frame forming the skeleton. According to this structure, when the pollution is serious, the filter can be replaced, and the frame can be used continuously. Therefore, the user only needs to purchase the filter and replace the existing filter on the frame, so the frame can be used permanently, thereby reducing the replacement cost of the filter assembly.

[0040] The plurality of filters constituting the filter assembly of the present invention may each have a handle. These handles are located at positions corresponding to the edges of the filters and can be pulled in a direction that can provide a force for separating the filters from the frame. Therefore, the user can use the handles to operate the filters, thereby improving the convenience of the user. Since the handles are located at positions corresponding to the edges of the filters, the area through which air passes through the filters will not be reduced, thereby maximizing the performance of the filters while facilitating operation.

[0041] On the other hand, there are a plurality of filters constituting the filter assembly of the present invention, and at least one of the plurality of filters can be configured to filter pollutants different from those of another filter. In other words, the plurality of filters can be configured to remove different pollutants respectively. According to this configuration, the user can selectively use the filter assembly by using a filter that can perform a specific function according to the user's use environment. Therefore, it has the effect of being able to meet the various requirements of users who use the filter assembly in various environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] Hereinafter, some embodiments of the present invention are described in detail by means of exemplary drawings. It should be noted that when adding reference numerals to the constituent elements of each figure, the same constituent elements, even if shown in different figures, are given the same reference numerals as much as possible. In addition, when describing the embodiments of the present invention, if it is determined that the specific description of the relevant known structure or function hinders the understanding of the embodiments of the present invention, its detailed description is omitted.

[0085] The filter assembly according to the embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 and Figure 2 It can be seen that the filter assembly 1 may include a frame 10 and a plurality of filters 30 .

[0086] The frame 10 can form the skeleton of the filter assembly 1. The filter 30 can be loaded and unloaded on the frame 10. In the frame 10, the first base 12 and the second base 14 can be parallel to each other. The first base 12 and the second base 14 can be respectively configured as annular plates. A first through hole 12' can be formed through the first base 12, and a second through hole 14' can be formed through the second base 14.

[0087] A plurality of connecting posts 16 may be provided to connect the first base 12 and the second base 14 at a predetermined interval. In the present embodiment, two connecting posts 16 extend side by side to connect the first base 12 and the second base 14 to each other. The connecting posts 16 may be orthogonally connected to the first base 12 and the second base 14, respectively. The connecting posts 16 are plate-shaped with a predetermined width. The thickness of the connecting posts 16 is preferably as thin as possible. This is because if the thickness of the connecting posts 16 becomes thicker, the area where the filter 30 is located becomes narrower.

[0088] The connecting column 16 may include an inner column stopper 18 and an outer column stopper 19. The connecting column 16 may include an inner column stopper 18 on one side in the width direction and an outer column stopper 19 on the other side in the width direction. The outer column stopper 19 may be exposed to the appearance of the filter assembly 1. The inner column stopper 18 may be exposed to the space formed by penetrating the center of the filter assembly 1. The inner column stopper 18 may extend along one side in the width direction of the connecting column 16 corresponding to the first through hole 12' and the second through hole 14'. The inner column stopper 18 and the outer column stopper 19 may be formed as a whole and continuously. However, the inner column stopper 18 or the outer column stopper 19 may be formed intermittently as long as there is no problem in fixing the filter 30. That is, the inner column stopper 18 or the outer column stopper 19 may also be separated into a plurality of parts.

[0089] The cross section including the connecting column 16 , the inner column stopper 18 , and the outer column stopper 19 may be in an “H” shape. The inner column stopper 18 and the outer column stopper 19 may stop the corresponding edges of the filter 30 so that the filter 30 cannot be removed from the frame 10 at will.

[0090] In this embodiment, two connecting posts 16 are arranged at an interval of 180 degrees, which can divide the area where the filter 30 is arranged into two, so that the filter 30 can cover an area of ​​180 degrees.

[0091] A first inner stopper rib 20 may be formed along an edge of the first through hole 12' of the first base 12. The first inner stopper rib 20 may include a portion of the inner column stopper 18 and be annular as a whole. The first inner stopper rib 20 may be formed to be orthogonal to the first base 12. The first inner stopper rib 20 may protrude toward the second base 14.

[0092] A plurality of first outer stopper protrusions 22 may be formed along the outer edge of the first base 12. The first outer stopper protrusions 22 may be formed protrudingly on the first base 12. The first outer stopper protrusions 22 can prevent the filter 30 from arbitrarily detaching from the frame 10. However, the protrusion of the first outer stopper protrusions 22 should not make it difficult to install the filter 30 on the frame 10. Therefore, the protrusion of the first outer stopper protrusions 22 should be less than the protrusion of the first inner stopper rib 20. That is, the first outer stopper protrusions 22 are formed to be lower than the height of the first inner stopper rib 20. The first outer stopper protrusions 22 may be a simple protruding protrusion shape, but differently, they may also be protrusions protruding from the front end of a cantilever-shaped structure.

[0093] A second inner stopper rib 24 may be formed along an edge of the second through hole 14' of the second base 14. The second inner stopper rib 24 may include a portion of the inner column stopper 18 and be annular as a whole. The second inner stopper rib 24 may be formed to be orthogonal to the second base 14. The second inner stopper rib 24 may protrude toward the first base 12.

[0094] A plurality of second outer stopper protrusions 26 may be formed along the outer edge of the second base 14. The second outer stopper protrusions 26 may be formed protrudingly on the second base 14. The second outer stopper protrusions 26 can prevent the filter 30 from arbitrarily detaching from the frame 10. However, the protrusion of the second outer stopper protrusions 26 should not make it difficult to install the filter 30 on the frame 10. Therefore, the protrusion of the second outer stopper protrusions 26 should be smaller than the protrusion of the second inner stopper rib 20. The second outer stopper protrusions 26 may be a simple protruding protrusion shape, but differently, may also be a protrusion protruding from the front end of a cantilever-shaped structure.

[0095] The filter 30 is a component for filtering various pollutants such as dust, odor, and viruses. The filter 30 is installed in the frame 10 for use, and a plurality of filters 30 can be installed in the frame 10. In the present embodiment, two filters 30 are used. Each of the filters 30 can have the same shape. The filter 30 is located in the area where air passes through the filter assembly 1 of the present invention, and can be cylindrical in shape as a whole. That is, in the present embodiment, if two filters 30 are installed in the frame 10, the overall shape can be cylindrical. Therefore, the filter 30 of the present embodiment can have a circumferential angle of 180 degrees.

[0096] The filter 30 may have a plurality of filter parts that perform the function of filtering specific pollutants. In the illustrated embodiment, there are a first filter part 31, a second filter part 32, and a third filter part 33. For example, the first filter part 31 can filter dust, the second filter part 32 can remove odors, and the third filter part 33 can filter viruses. However, in addition to this, the filter parts 31, 32, and 33 of the filter 30 can also be composed of components with various functions. In addition, the number of the filter parts 31, 32, and 33 can be various. For example, there can also be only the first filter part 31. Or there can be both the first filter part 31 and the second filter part 32. In the illustrated embodiment, the first filter part 31 is manufactured separately, and the second filter part 32 and the third filter part 33 are manufactured integrally.

[0097] The filter parts 31, 32, and 33 are all concentric and may have a predetermined radius of curvature. In the illustrated embodiment, the first filter part 31 is located at the outermost side, and the second filter part 32 and the third filter part 33 are sequentially arranged toward the center side of the radius of curvature. If only one filter 30 is observed, the filter parts 31, 32, and 33 are all semi-cylindrical in shape.

[0098] The filter 30 includes a first decorative plate 34 and a second decorative plate 36. The first decorative plate 34 and the second decorative plate 36 can combine the filter parts 31, 32, and 33 in one piece, and can form both side ends of the filter 30. The first decorative plate 34 and the second decorative plate 36 are parts of the first base 12 and the second base 14 of the frame 10, and can be configured to have the same shape as the corresponding parts of the first base 12 and the second base 14. That is, the first decorative plate 34 and the second decorative plate 36 can be configured to have a semicircular ring shape.

[0099] Figure 6 The bottom stereogram of the second decorative plate 36 is shown. For reference, the first decorative plate 34 and the second decorative plate 36 are symmetrical structures, so the structure is described based on the second decorative plate 36. The end rib 37 protrudes a predetermined length around the edge of the second decorative plate 36. The end rib 37 can be formed around the edge of the entire second decorative plate 36. According to design conditions, the end rib 37 can also be formed intermittently. This structure can be formed within the range where there is no problem in fixing the filter parts 31, 32, and 33.

[0100] The second decorative plate 36 may have a spacer rib 38, and the spacer rib 38 can form a gap between the first filter part 31 and the second filter part 32. The spacer rib 38 is formed on the surface of the second decorative plate 36 facing the first decorative plate 34. The two spacer ribs 38 can be formed at a specified interval. Alternatively, the width of a spacer rib 38 can be formed to be the same as the required interval between the first filter part 31 and the second filter part 32. If the spacer rib 38 is present, a space can be formed between the first filter part 31 and the second filter part 32. Due to the existence of this space, the flow of air through the filter parts 31, 32, and 33 can be relatively smoother.

[0101] On the other hand, the portion of the filter 30 that is opposite to the connection column 16 of the frame 10 may have a baffle 40. The baffle 40 can prevent the air passing through the filter 30 from leaking. That is, the air flowing through the filter parts 31, 32, and 33 does not flow to the portion with the baffle 40. In this way, the air can pass through the filter parts 31, 32, and 33 in sequence and flow smoothly to the inside of the filter assembly 1. The baffle 40 can be made of a synthetic resin material with a specified rigidity. Alternatively, a non-woven fabric with a specified rigidity can be used as the baffle 40.

[0102] The filter 30 may have a handle 42. The handle 42 is used to facilitate the user to operate the filter 30. The handle 42 may be located adjacent to the first decorative plate 34 or the second decorative plate 36. This is to prevent the handle 42 from blocking the air passing area of ​​the first filter portion 31. A plurality of handles 42 may be provided in one filter 30. On the other hand, the position of the handle 42 may be selected in consideration of the direction in which the filter 30 is separated from the frame 10.

[0103] Secondly, in Fig.11 Reference Fig.18 The structure of a filter assembly 101 according to another embodiment of the present invention will be described.

[0104] The filter assembly 101 of this embodiment can be manufactured by installing a plurality of filters 130 in the frame 110. In this embodiment, three filters 130 are used. That is, in the above-mentioned embodiment, one filter 30 occupies an area of ​​180 degrees in the entire cylindrical area, but in this embodiment, one filter 130 occupies an area of ​​120 degrees.

[0105] The frame 110 may form a skeleton of the filter assembly 101. The filter 130 may be mounted or removed from the frame 110. On the frame 110, a first base 112 and a second base 114 may be parallel to each other. The first base 112 and the second base 114 may be respectively configured as an annular plate. A first through hole 112' may be formed through the first base 112, and a second through hole 114' may be formed through the second base 114.

[0106] A plurality of connecting posts 116 may be provided to connect the first base 112 and the second base 114 at a predetermined interval. In the present embodiment, three connecting posts 116 extend side by side to connect the first base 112 and the second base 114 to each other. The connecting posts 116 may be orthogonally connected to the first base 112 and the second base 114, respectively. The connecting posts 116 are plate-shaped with a predetermined width. The thickness of the connecting posts 116 is preferably as thin as possible. The reason is that if the thickness of the connecting posts 116 becomes thicker, the area where the filter 130 is located becomes narrower.

[0107] The connecting column 116 may have an inner column stopper 118. The inner column stopper 118 may be on one side of the connecting column 116 in the width direction. The inner column stopper 118 may be exposed in a space formed by penetrating the center of the filter assembly 101. The inner column stopper 118 may extend along one side of the connecting column 116 in the width direction corresponding to the first through hole 112' and the second through hole 114'. The inner column stopper 118 may be formed as a whole and continuously. However, as long as there is no problem in fixing the filter 130, the inner column stopper 118 may be formed intermittently. That is, the inner column stopper 118 may also be separated into a plurality of parts.

[0108] The cross section of the connecting column 116 and the inner column stopper 118 can be configured in a “T” shape. The inner column stopper 118 can stop the corresponding edge of the filter 130 so that the filter 130 is firmly disposed on the frame 110 .

[0109] In this embodiment, three connecting posts 116 are arranged at intervals of 120 degrees, so that the area where the filter 130 is arranged can be divided into three parts, so that the filter 130 can cover an area of ​​120 degrees.

[0110] A first inner stopper rib 120 may be formed along an edge of the first through hole 112' of the first base 112. The first inner stopper rib 120 may include a portion of the inner column stopper 118 and be annular as a whole. The first inner stopper rib 120 may be formed to be orthogonal to the first base 112. The first inner stopper rib 120 may protrude toward the second base 114.

[0111] A plurality of first outer stopper protrusions 122 may be formed along the outer edge of the first base 112. The first outer stopper protrusions 122 may be formed protrudingly on the first base 112. The first outer stopper protrusions 122 can prevent the filter 130 from arbitrarily detaching from the frame 110. However, the protrusion of the first outer stopper protrusions 122 should not make it difficult to install the filter 130 on the frame 110. Therefore, the protrusion of the first outer stopper protrusions 122 should be less than the protrusion of the first inner stopper rib 120. That is, the first outer stopper protrusions 122 are formed to be lower than the height of the first inner stopper rib 120. The first outer stopper protrusions 122 may be a simple protruding protrusion shape, but differently, they may also be protrusions protruding from the front end of a cantilever-shaped structure.

[0112] A second inner stopper rib 124 may be formed along an edge of the second through hole 114' of the second base 114. The second inner stopper rib 124 may include a portion of the inner column stopper 118 and be annular as a whole. The second inner stopper rib 124 may be formed to be orthogonal to the second base 114. The second inner stopper rib 124 may protrude toward the first base 112.

[0113] A plurality of second outer stopper protrusions 126 may be formed along the outer edge of the second base 114. The second outer stopper protrusions 126 may be formed protrudingly on the second base 114. The second outer stopper protrusions 126 can prevent the filter 130 from arbitrarily detaching from the frame 110. However, the protrusion of the second outer stopper protrusions 126 should not make it difficult to install the filter 130 on the frame 110. Therefore, the protrusion of the second outer stopper protrusions 126 should be smaller than the protrusion of the second inner stopper rib 120. The second outer stopper protrusions 126 may be a simple protruding protrusion shape, but differently, may also be a protrusion protruding from the front end of a cantilever-shaped structure.

[0114] The filter 130 is a component for filtering various pollutants such as dust, odor, and viruses. The filter 130 is installed on the frame 110 for use, and the frame 110 can be installed with a plurality of filters 130. In the present embodiment, three filters 130 are used. Each of the filters 130 can have the same shape. The filter 130 is located in the area where air passes through the filter assembly 101 of the present invention, and can be cylindrical in shape as a whole. That is, in the present embodiment, if three filters 130 are installed on the frame 110, the overall shape can be cylindrical. Therefore, the circumferential angle of the filter 130 of the present embodiment can be 120 degrees.

[0115] The filter 130 may have a plurality of filter parts that perform the function of filtering specific pollutants. In the illustrated embodiment, there are a first filter part 131, a second filter part 132, and a third filter part 133. For example, the first filter part 131 can filter dust, the second filter part 132 can remove odors, and the third filter part 133 can filter viruses. However, in addition to this, the filter parts 131, 132, and 133 of the filter 130 can also be composed of components with various functions. In addition, the number of the filter parts 131, 132, and 133 can be diverse. For example, there can also be only the first filter part 131. Or there can be both the first filter part 131 and the second filter part 132. In the illustrated embodiment, the first filter part 131 is manufactured separately, and the second filter part 132 and the third filter part 133 are manufactured in one piece.

[0116] The filter parts 131, 132, and 133 are all concentric and may have a predetermined radius of curvature. In the illustrated embodiment, the first filter part 131 is located at the outermost side, and the second filter part 132 and the third filter part 133 are sequentially arranged toward the center side of the radius of curvature. If only one filter 130 is observed, the filter parts 131, 132, and 133 are all 1 / 3 cylindrical.

[0117] The filter 310 includes a first decorative plate 134 and a second decorative plate 136. The first decorative plate 134 and the second decorative plate 136 can combine the filter parts 131, 132, and 133 in one piece, and can form both side ends of the filter 130. The first decorative plate 134 and the second decorative plate 136 are parts of the first base 112 and the second base 114 of the frame 110, and can be configured to have the same shape as the corresponding parts of the first base 112 and the second base 114. That is, the first decorative plate 134 and the second decorative plate 136 can be configured to have a circular shape with a central angle of 120 degrees.

[0118] Fig.15A bottom stereogram of the second decorative plate 136 is shown. For reference, the first decorative plate 134 and the second decorative plate 136 are symmetrical structures, so the structure is described based on the second decorative plate 136. The end rib 137 protrudes a specified length around the edge of the second decorative plate 136. The end rib 137 can be formed around the edge of the entire second decorative plate 136. Depending on the design conditions, the end rib 137 can also be formed intermittently. This structure can be constructed within the range where there is no problem in fixing the filter parts 131, 132, and 133.

[0119] The second decorative plate 136 may have a spacer rib 138, and the spacer rib 138 can form a gap between the first filter part 131 and the second filter part 132. The spacer rib 138 is formed on the surface of the second decorative plate 136 facing the first decorative plate 134. The two spacer ribs 138 can be formed at a specified interval. Alternatively, the width of a spacer rib 138 can be formed to be the same as the required interval between the first filter part 131 and the second filter part 132. If the spacer rib 138 is present, a space can be formed between the first filter part 131 and the second filter part 132. Due to the existence of this space, the flow of air through the filter parts 131, 132, and 133 can be relatively smoother.

[0120] On the other hand, a baffle 140 may be provided at a portion of the filter 130 that is opposite to the connection column 116 of the frame 110. The baffle 140 may prevent the air passing through the filter 130 from leaking. That is, the air flowing through the filter parts 131, 132, and 133 is prevented from flowing toward the portion where the baffle 140 is provided. Thus, the air may pass through the filter parts 131, 132, and 133 in sequence and flow smoothly toward the inside of the filter assembly 101. The baffle 140 may be made of a synthetic resin material having a predetermined rigidity. Alternatively, a non-woven fabric having a predetermined rigidity may be used as the baffle 140.

[0121] The filter 130 may have a handle 142. The handle 142 is used to facilitate the user to operate the filter 130. The handle 142 may be located adjacent to the first decorative plate 134 or the second decorative plate 136. This is to prevent the handle 142 from blocking the air passing area of ​​the first filter portion 131. A filter 130 may have a plurality of handles 142. On the other hand, the position of the handle 142 may be selected in consideration of the direction in which the filter 30 is separated from the frame 10.

[0122] In this embodiment, the handles 142 may be located at positions corresponding to the middle portions of the outer edges of the first decorative plate 134 and the second decorative plate 136. As in this embodiment, if there are two handles 142, only one of the two handles 142 may be used, or both handles 142 may be used simultaneously to operate the filter 130.

[0123] Secondly, in Fig.19 Reference Fig.25 Another embodiment of the present invention is described below. The filter assembly 201 of this embodiment may include a frame 210 and a plurality of filters 230 .

[0124] The frame 210 may form a skeleton of the filter assembly 201. The filter 230 may be mounted or removed on the frame 210. On the frame 210, a first base 212 and a second base 214 may be parallel to each other. The first base 212 and the second base 214 may be respectively configured as an annular plate. A first through hole 212' may be formed through the first base 212, and a second through hole 214' may be formed through the second base 214.

[0125] A plurality of connecting posts 216 may be provided to connect the first base 212 and the second base 214 at a predetermined interval. In the present embodiment, four connecting posts 216 extend side by side to connect the first base 212 and the second base 214 to each other. The connecting posts 216 may be orthogonally connected to the first base 212 and the second base 214, respectively. The connecting posts 216 are plate-shaped with a predetermined width. The thickness of the connecting posts 216 is preferably as thin as possible. The reason is that if the thickness of the connecting posts 216 becomes thicker, the area where the filter 230 is located becomes narrower.

[0126] The connecting column 216 may have an inner column stopper 218. The inner column stopper 218 may be on one side in the width direction of the connecting column 216. The inner column stopper 218 may be exposed in a space formed by penetrating the center of the filter assembly 201. The inner column stopper 218 may extend along one side in the width direction of the connecting column 216 corresponding to the first through hole 212' and the second through hole 214'. The inner column stopper 218 may be formed as a whole and continuously. However, as long as there is no problem in fixing the filter 230, the inner column stopper 218 may be formed intermittently. That is, the inner column stopper 218 may also be separated into a plurality of pieces. The inner column stopper 218 may stop the corresponding edge of the filter 230 so that the filter 230 is firmly set on the frame 210.

[0127] A portion of the connecting posts 216 may have an outer post stopper 219. Fig.21 As shown, two of the four connecting columns 216 are formed with outer column stoppers 219. The outer column stoppers 219 are formed on two connecting columns 216 facing each other. Here, since the two connecting columns 216 formed with the outer column stoppers 219 also have inner column stoppers 218, the entirety of the connecting column 216 may have an "H"-shaped cross section. On the other hand, the connecting column 216 without the outer column stoppers 219 has only the connecting column 216 and the inner column stoppers 218, and thus the cross section may have a "T"-shaped cross section.

[0128] The inner column stopper 218 may be located on one side of the width direction of all the connecting columns 216, and the outer column stopper 219 may be located on the other side of the width direction of the connecting column 216. The outer column stopper 219 may be exposed from the appearance of the filter assembly 201. The inner column stopper 218 may extend along one side of the width direction of the connecting column 216 corresponding to the first through hole 212' and the second through hole 214'. The inner column stopper 218 and the outer column stopper 219 may be respectively formed as a whole and continuously. However, the inner column stopper 218 or the outer column stopper 219 may be formed intermittently as long as there is no problem in fixing the filter 230. That is, the inner column stopper 218 or the outer column stopper 219 may also be separated into a plurality of parts. The inner column locking piece 218 and the outer column locking piece 219 can lock the corresponding edges of the filter 230 so that the filter 230 cannot be arbitrarily removed from the frame 210 .

[0129] The direction in which the outer column stopper 219 protrudes from the connecting column 216 may be the direction in which the filter 230 is mounted on or separated from the frame 210. Therefore, in the connecting column 216 having the outer column stopper 219, the baffle 240 of the filter 230 moves toward a direction approaching the surface of the connecting column 216 or away from the surface of the connecting column 216.

[0130] In this embodiment, four connecting posts 216 are arranged at 90 degree intervals, which divides the area where the filter 230 is arranged into four areas, so that the filter 230 can cover an area of ​​360 degrees.

[0131] A first inner stopper rib 220 may be formed along an edge of the first through hole 212' of the first base 212. The first inner stopper rib 220 may include a portion of the inner column stopper 218 and be annular as a whole. The first inner stopper rib 220 may be formed to be orthogonal to the first base 212. The first inner stopper rib 220 may protrude toward the second base 214.

[0132] A plurality of first outer stopper protrusions 222 may be formed along the outer edge of the first base 212. The first outer stopper protrusions 222 may be formed protrudingly on the first base 212. The first outer stopper protrusions 222 can prevent the filter 230 from arbitrarily detaching from the frame 210. However, the protrusion degree of the first outer stopper protrusions 222 should not make it difficult to install the filter 230 on the frame 210. Therefore, the protrusion degree of the first outer stopper protrusions 222 should be less than the protrusion degree of the first inner stopper rib 220. That is, the height of the first outer stopper protrusions 222 is lower than that of the first inner stopper rib 220. The first outer stopper protrusions 222 may be a simple protruding protrusion shape, but differently, it may also be a protrusion protruding from the front end of a cantilever-shaped structure.

[0133] On the other hand, a post hook 223 may be formed in the connecting post 216 where the outer post stopper 219 is not formed. The post hook 223 is cantilevered and has a protruding portion at the front end, so as to stop one side of the filter 230. The post hook 223 may play the same role as the first outer protrusion 222.

[0134] A second inner stopper rib 224 may be formed along an edge of the second through hole 214' of the second base 214. The second inner stopper rib 224 may include a portion of the inner column stopper 218 and be annular as a whole. The second inner stopper rib 224 may be formed to be orthogonal to the second base 214. The second inner stopper rib 224 may protrude toward the first base 212.

[0135] A plurality of second outer stopper protrusions 226 may be formed along the outer edge of the second base 214. The second outer stopper protrusions 226 may be formed protrudingly on the second base 214. The second outer stopper protrusions 226 can prevent the filter 230 from arbitrarily detaching from the frame 210. However, the protrusion of the second outer stopper protrusions 226 should not make it difficult to install the filter 230 on the frame 210. Therefore, the protrusion of the second outer stopper protrusions 226 should be smaller than the protrusion of the second inner stopper rib 220. Although the second outer stopper protrusions 226 may be a simple protruding protrusion shape, differently from this, it may also be a protrusion protruding from the front end of the cantilever-shaped structure.

[0136] The filter 230 filters various pollutants such as dust, odor, and viruses. The filter 230 is installed on the frame 210 for use, and a plurality of filters 230 can be installed on the frame 210. In this embodiment, four filters 230 are used. The filters 230 can have the same shape respectively. The filter 230 can be located in the area where air passes through the filter assembly 201 of the present invention, and can be cylindrical in shape as a whole. That is, in this embodiment, if four filters 230 are installed on the frame 210, the overall shape can be cylindrical. Therefore, the circumferential angle of the filter 230 of this embodiment can be 90 degrees.

[0137] The filter 230 may have a plurality of filter parts that perform the function of filtering specific pollutants. In the illustrated embodiment, there are a first filter part 231, a second filter part 232, and a third filter part 233. For example, the first filter part 231 can filter dust, the second filter part 232 can remove odors, and the third filter part 233 can filter viruses. However, in addition to this, the filter parts 231, 232, and 233 of the filter 230 can also be composed of components with various functions. In addition, the number of the filter parts 231, 232, and 233 can be diverse. For example, there can also be only the first filter part 231. Or there can be both the first filter part 231 and the second filter part 232. In the illustrated embodiment, the first filter part 231 is manufactured separately, and the second filter part 232 and the third filter part 233 are manufactured in one piece.

[0138] The filter parts 231, 232, and 233 are all concentric and may have a predetermined radius of curvature. In the illustrated embodiment, the first filter part 231 is located at the outermost side, and the second filter part 232 and the third filter part 233 are sequentially arranged toward the center side of the radius of curvature. If only one filter 230 is observed, the filter parts 231, 232, and 233 are all 1 / 4 cylindrical in shape.

[0139] The filter 230 includes a first decorative plate 234 and a second decorative plate 236. The first decorative plate 234 and the second decorative plate 236 can combine the filter parts 231, 232, and 233 in one piece, and can form both side ends of the filter 230. The first decorative plate 234 and the second decorative plate 236 are parts of the first base 212 and the second base 214 of the frame 210, and can be configured in the same shape as the corresponding parts of the first base 212 and the second base 214. That is, the first decorative plate 234 and the second decorative plate 236 can be configured in a semicircular ring shape.

[0140] Fig.23A bottom stereogram of the second decorative plate 236 is shown. For reference, the first decorative plate 234 and the second decorative plate 236 are symmetrical structures, so the structure is described based on the second decorative plate 236. The end rib 237 protrudes a specified length around the edge of the second decorative plate 236. The end rib 237 can be formed around the edge of the entire second decorative plate 236. Depending on the design conditions, the end rib 237 can also be formed intermittently. This structure can be constructed within the range where there is no problem in fixing the filter parts 231, 232, and 233.

[0141] The second decorative plate 236 may include a spacer rib 238, and the spacer rib 238 can form a gap between the first filter part 231 and the second filter part 232. The spacer rib 238 is formed on the surface of the second decorative plate 236 facing the first decorative plate 234. Two spacer ribs 238 can be formed at a specified interval. Alternatively, the width of a spacer rib 238 can be formed to be the same as the required interval between the first filter part 231 and the second filter part 232. If the spacer rib 238 is present, a space can be formed between the first filter part 231 and the second filter part 232. Due to the presence of this space, the flow of air through the filter parts 231, 232, and 233 can be relatively smoother.

[0142] On the other hand, a baffle 240 may be provided at a portion of the filter 230 that is opposite to the connection column 216 of the frame 210. The baffle 240 may prevent the air passing through the filter 230 from leaking. That is, the air flowing through the filter parts 231, 232, and 233 may not flow to the portion where the baffle 240 is provided. Thus, the air may pass through the filter parts 231, 232, and 233 in sequence and flow smoothly to the inside of the filter assembly 201. The baffle 240 may be made of a synthetic resin material having a predetermined rigidity. Alternatively, a non-woven fabric having a predetermined rigidity may be used as the baffle 240.

[0143] The filter 230 may be provided with a handle 242. The function of the handle 242 is to facilitate the user to operate the filter 230. The handle 242 may be located adjacent to the first decorative panel 234 or the second decorative panel 236. However, in the present embodiment, the handle 242 is located adjacent to the baffle 240. The position of the handle 242 is selected so that the handle 242 does not block the air passing area of ​​the first filter portion 231. There may be a plurality of handles 242 in one filter 230. On the other hand, the position of the handle 242 may be selected in consideration of the direction in which the filter 230 is separated from the frame 10. Therefore, in the present embodiment, the handle 242 is located at a position around the middle of the baffle 240 so that the handle 242 can be pulled in the direction in which the outer column stopper 219 extends.

[0144] Figures 26 to 30 2 shows a filter assembly 301 according to another embodiment of the present invention. The filter assembly 301 according to this embodiment may include a frame 310 and a plurality of filters 330 .

[0145] The frame 310 may form a skeleton of the filter assembly 301. The filter 330 may be mounted or removed from the frame 310. The first base 312, the second base 314, and the third base 315 may be arranged in parallel in sequence at a predetermined interval on the frame 310. The first base 312 and the third base 315 may be arranged opposite to each other, and the third base 315 and the second base 314 may be arranged opposite to each other.

[0146] The first base 312, the second base 314 and the third base 315 can be respectively configured as annular plates. A first through hole 312' can be formed through the first base 312, a second through hole 314' can be formed through the second base 314, and a third through hole 315' can be formed through the third base 315.

[0147] A plurality of connecting posts 316 may be provided to connect the first base 312, the second base 314 and the third base 315 at predetermined intervals. In the present embodiment, the three connecting posts 316 extend side by side to connect the first base 312, the second base 314 and the third base 315 to each other. In the present embodiment, the connecting posts 316 may be connected to the outer edges of the first base 312, the second base 314 and the third base 315. In the present embodiment, the three connecting posts 316 may be arranged within an angle of 180 degrees in the circular area formed by the bases 312, 314, and 315. In this way, only when the connecting posts 316 are arranged within an angle of 180 degrees, the cylindrical filter 330 can be installed on or removed from the frame 310 without interfering with the connecting posts 316. Alternatively, the distance between the connecting posts 316 that are opposite to each other in the connecting posts 316 may be the same as or slightly larger than the outer diameter of the filter 330.

[0148] The connecting column 316 can be orthogonally connected to the first base 312, the second base 314 and the third base 315 respectively. The connecting column 316 is a plate with a predetermined width. The connecting column 316 is preferably as thin as possible. The reason is that if the width of the connecting column 316 becomes larger, the area where air passes through the filter 330 becomes narrower.

[0149] A plurality of first outer stopper protrusions 322 may be formed along the outer edge of the first base 312. The first outer stopper protrusions 322 may be formed protrudingly on the first base 312. The first outer stopper protrusions 322 can prevent the filter 330 from being arbitrarily separated from the frame 310. However, the protrusion degree of the first outer stopper protrusions 322 should not make it difficult to install the filter 330 on the frame 310. The first outer stopper protrusions 322 may be a simple protruding protrusion shape, but differently, may also be a protrusion protruding from the front end of a cantilever-shaped structure.

[0150] A plurality of second outer stopper protrusions 326 may be formed along the outer edge of the second base 314. The second outer stopper protrusions 326 may be formed protrudingly on the second base 314. The second outer stopper protrusions 326 can prevent the filter 330 from being arbitrarily separated from the frame 310. However, the protrusion degree of the second outer stopper protrusions 326 should not make it difficult to install the filter 330 on the frame 310. The second outer stopper protrusions 326 may be a simple protruding protrusion shape, but differently, they may also be protrusions protruding from the front end of a cantilever-shaped structure.

[0151] A plurality of third outer retaining protrusions 328 may be formed along the outer edge of the third base 315. Some of the third outer retaining protrusions 328 protrude toward the first base 312, and some protrude toward the second base 314. The reason is that the third outer retaining protrusions 328 respectively play the role of fixing the filter 330 located between the first base 312 and the third base 315 and the filter 330 located between the second base 314 and the third base 315. The third outer retaining protrusions 328 may be a simple protruding protrusion shape, but differently, they may also be protrusions protruding from the front end of the cantilever-shaped structure.

[0152] The filter 330 constituting the present embodiment is a component for filtering various pollutants such as dust, odor, and viruses. The filter 330 is installed on the frame 310 for use, and the frame 310 may be installed with a plurality of filters. In the present embodiment, two filters 330 are used. Each of the filters 330 may have the same shape. The filters 330 are located in the area where air passes through the filter assembly 301 of the present invention, and may be cylindrical in shape. That is, in the present embodiment, the two filters 330 are installed on the frame 310 at different heights from each other.

[0153] That is, one filter 330 is provided between the first base 312 and the third base 315, and another filter 330 is provided between the second base 314 and the third base 315. In this embodiment, in the filter assembly 301 having a cylindrical shape as a whole, another cylindrical filter 330 is arranged in a different layer.

[0154] On the other hand, the structure of the filter 330 is different from that of the filter described above only in the overall shape of the appearance, and thus the shapes of the various components are different, and other than that, they are substantially the same. Therefore, the description of the specific structure of the filter 330 is omitted. However, the 300 series of reference numerals are used in the drawings to indicate the structure corresponding to the structure of the filter 30, 130, 230 described above. The first filter part 331, the second filter part 332, and the third filter part 333 in each filter 330 are fixed by combining the first decorative plate 334 and the second decorative plate 336, and may have a handle 342.

[0155] Secondly, Figure 31 to Figure 33 Another embodiment of the present invention is shown in FIG. Filter assembly 401 of this embodiment may include a frame 410 and a plurality of filters 430 .

[0156] The frame 410 may form a skeleton of the filter assembly 401. The filter 430 may be mounted or removed from the frame 410. The first base 412, the second base 414, and the third base 415 may be arranged in parallel in sequence at a predetermined interval on the frame 410. The first base 412 and the third base 415 may be opposite to each other, and the third base 415 and the second base 414 may be opposite to each other.

[0157] The first base 412, the second base 414 and the third base 415 can be respectively configured as annular plates. A first through hole 412' can be formed through the first base 412, a second through hole 414' can be formed through the second base 414, and a third through hole 415' can be formed through the third base 415.

[0158] A plurality of connecting posts 416 may be provided to connect the first base 412, the second base 414, and the third base 415 at a predetermined interval. In the present embodiment, two connecting posts 416 extend side by side to connect the first base 412, the second base 414, and the third base 415 to each other. In the present embodiment, the connecting posts 416 may be located between the inner edge and the outer edge of the first base 412, the second base 414, and the third base 415 to connect them to each other. In the present embodiment, the two connecting posts 416 may be arranged at 180 degrees intervals in the circular area formed by the bases 412, 414, and 415.

[0159] The connecting column 416 may be orthogonally connected to the first base 412, the second base 414, and the third base 415, respectively. The connecting column 416 is in the shape of a plate having a predetermined width. The connecting column 416 is preferably as thin as possible. This is because if the thickness of the connecting column 416 increases, the area through which air passes through the filter 430 becomes narrower.

[0160] The connecting column 416 may include an inner column stopper 418 and an outer column stopper 419. The connecting column 416 may include an inner column stopper 418 on one side in the width direction and an outer column stopper 419 on the other side in the width direction. The outer column stopper 419 may be exposed to the appearance of the filter assembly 401. The inner column stopper 418 may be exposed to the space formed by penetrating the center of the filter assembly 401. The inner column stopper 418 may extend along one side in the width direction of the connecting column 416 corresponding to the first through hole 412', the second through hole 414', and the third through hole 415'. The inner column stopper 418 and the outer column stopper 419 may be formed as a whole and continuously. However, the inner column stopper 418 or the outer column stopper 419 may be formed intermittently as long as there is no problem in fixing the filter 430. That is, the inner column locking piece 418 or the outer column locking piece 419 may be separated into a plurality of pieces.

[0161] The cross section including the connecting column 416, the inner column stopper 418, and the outer column stopper 419 may be in an "H" shape. The inner column stopper 418 and the outer column stopper 419 may stop the corresponding edges of the filter 430 so that the filter 430 will not be arbitrarily removed from the frame 410.

[0162] In this embodiment, two connecting posts 416 are arranged at an interval of 180 degrees, which can divide the area where the filter 430 is arranged into two in one layer, so that the filter 430 can cover an area of ​​180 degrees.

[0163] A first inner stopper rib 420 may be formed along an edge of the first through hole 412' of the first base 412. The first inner stopper rib 420 may include a portion of the inner column stopper 418 and be annular as a whole. The first inner stopper rib 420 may be formed to be orthogonal to the first base 412. The first inner stopper rib 420 may protrude toward the third base 415.

[0164] A plurality of first outer stopper protrusions 422 may be formed along the outer edge of the first base 412. The first outer stopper protrusions 422 may be formed protrudingly on the first base 412. The first outer stopper protrusions 422 can prevent the filter 430 from arbitrarily detaching from the frame 410. However, the protrusion degree of the first outer stopper protrusions 422 should not make it difficult to install the filter 430 on the frame 410. Therefore, the protrusion degree of the first outer stopper protrusions 422 should be less than the protrusion degree of the first inner stopper rib 420. That is, the first outer stopper protrusions 422 are formed to be lower than the height of the first inner stopper rib 420. The first outer stopper protrusions 422 may be a simple protruding protrusion shape, but differently, they may also be protrusions protruding from the front end of a cantilever-shaped structure.

[0165] A second inner stopper rib 424 may be formed along an edge of the second through hole 414' of the second base 414. The second inner stopper rib 424 may include a portion of the inner column stopper 418 and be annular as a whole. The second inner stopper rib 424 may be formed to be orthogonal to the second base 414. The second inner stopper rib 424 may protrude toward the third base 415.

[0166] A plurality of second outer stopper protrusions 426 may be formed along the outer edge of the second base 414. The second outer stopper protrusions 426 may be formed protrudingly on the second base 414. The second outer stopper protrusions 426 can prevent the filter 430 from arbitrarily detaching from the frame 410. However, the protrusion of the second outer stopper protrusions 426 should not make it difficult to install the filter 430 on the frame 410. Therefore, the protrusion of the second outer stopper protrusions 426 should be smaller than the protrusion of the second inner stopper rib 424. The second outer stopper protrusions 426 may be a simple protruding protrusion shape, but differently, may also be a protrusion protruding from the front end of a cantilever-shaped structure.

[0167] A third inner retaining member rib 427 may be formed along the edge of the third through hole 415' of the third base 415. The third inner retaining member rib 427 may include a portion of the inner column retaining member 418 and be annular as a whole. The third inner retaining member rib 427 may be formed to be orthogonal to the third base 415. The third inner retaining member rib 427 may protrude toward the first base 412 and the second base 414, respectively.

[0168] A plurality of third outer stopper protrusions 428 may be formed along the outer edge of the third base 415. The third outer stopper protrusions 428 may be formed protrudingly on the third base 415. The third outer stopper protrusions 428 can prevent the filter 430 from arbitrarily detaching from the frame 410. However, the protrusion of the third outer stopper protrusions 428 should not make it difficult for the filter 430 to be installed on the frame 410. Therefore, the protrusion of the third outer stopper protrusions 428 should be less than the protrusion of the third inner stopper rib 427. The third outer stopper protrusions 428 may be a simple protruding protrusion shape, but differently from this, it may also be a protrusion protruding from the front end of a cantilever-shaped structure. Some of these third outer stopper protrusions 428 may protrude toward the first base 412, and some may protrude toward the second base 414.

[0169] The filter 430 is a component for filtering various pollutants such as dust, odor, and viruses. The filter 430 is installed on the frame 410 for use, and the frame 410 can be installed with a plurality of filters 430. In the present embodiment, two filters 430 are used in each layer, for a total of four filters 430. Each of the filters 430 can have the same shape. The filter 430 is located in the area where air passes through the filter assembly 401 of the present invention, and can be cylindrical in shape as a whole. That is, in the present embodiment, if two filters 430 are installed on the frame 10 in one layer, the overall shape can be cylindrical.

[0170] In this embodiment, the filter 430 is constructed similarly to the above-described embodiment. Figure 1 The embodiment shown in FIG. 4 is the same. However, based on the attached drawings, the height of the filter 430 is relatively low. Therefore, in this embodiment, the description of the specific structure of the filter 430 is omitted, and the corresponding components are given the reference numerals of the 400 series. For example, the first filter part 431, the third filter part 433, the first decorative plate 434, the second decorative plate 436, the handle 442, etc. are shown in the figure.

[0171] Secondly, Figure 34 to Figure 36 Another embodiment of the present invention is shown in FIG. Filter assembly 501 of this embodiment may include a frame 510 and a plurality of filters 530 .

[0172] The frame 510 may form a skeleton of the filter assembly 501. The filter 530 may be mounted or removed from the frame 510. The first base 512, the second base 514, and the third base 515 may be arranged in order and in parallel at predetermined intervals on the frame 510. The first base 512 and the third base 515 may be arranged opposite to each other, and the third base 515 and the second base 514 may be arranged opposite to each other.

[0173] The first base 512, the second base 514 and the third base 515 can be respectively configured as annular plates. A first through hole 512' can be formed through the first base 512, a second through hole 514' can be formed through the second base 514, and a third through hole 515' can be formed through the third base 515.

[0174] A plurality of connecting posts 516 may be provided to connect the first base 512, the second base 514, and the third base 515 at predetermined intervals. In the present embodiment, the three connecting posts 516 extend side by side to connect the first base 512, the second base 514, and the third base 515 to each other. In the present embodiment, the connecting posts 516 may be located between the inner edge and the outer edge of the first base 512, the second base 514, and the third base 515 to connect them to each other. In the present embodiment, the three connecting posts 516 may be arranged at intervals of 120 degrees in the circular area formed by the bases 512, 514, and 515.

[0175] The connecting column 516 may be orthogonally connected to the first base 512, the second base 514, and the third base 515, respectively. The connecting column 516 is in the shape of a plate having a predetermined width. The connecting column 516 is preferably as thin as possible. This is because if the thickness of the connecting column 516 increases, the area through which air passes through the filter 530 becomes narrower.

[0176] The connecting column 516 may be provided with an inner column stopper 518. The connecting column 516 may be provided with the inner column stopper 518 on one side in the width direction. The inner column stopper 518 may be exposed to a space formed by penetrating the center of the filter assembly 501. The inner column stopper 518 may extend along one side in the width direction of the connecting column 516 corresponding to the first through hole 512', the second through hole 514', and the third through hole 515'. The inner column stopper 518 may be formed as a whole and continuously. However, as long as there is no problem in fixing the filter 530, the inner column stopper 518 may be formed intermittently. That is, the inner column stopper 518 may also be separated into a plurality of parts.

[0177] The cross section including the connecting column 516 and the inner column locking piece 518 may be in a “T” shape. The inner column locking piece 518 may lock the corresponding edge of the filter 530 so that the filter 530 can be firmly disposed on the frame 510 .

[0178] In this embodiment, three connecting posts 516 are arranged at intervals of 120 degrees, which can divide the area where the filter 530 is arranged into three areas, so that the filter 530 can cover an area of ​​120 degrees.

[0179] A first inner stopper rib 520 may be formed along an edge of the first through hole 512' of the first base 512. The first inner stopper rib 520 may include a portion of the inner column stopper 518 and be annular as a whole. The first inner stopper rib 520 may be formed to be orthogonal to the first base 512. The first inner stopper rib 520 may protrude toward the third base 515.

[0180] A plurality of first outer stopper protrusions 522 may be formed along the outer edge of the first base 512. The first outer stopper protrusions 522 may be formed protrudingly on the first base 512. The first outer stopper protrusions 522 can prevent the filter 530 from arbitrarily detaching from the frame 510. However, the protrusion degree of the first outer stopper protrusions 522 should not make it difficult to install the filter 530 on the frame 510. Therefore, the protrusion degree of the first outer stopper protrusions 522 should be less than the protrusion degree of the first inner stopper rib 520. That is, the first outer stopper protrusions 522 are formed to be lower than the height of the first inner stopper rib 520. The first outer stopper protrusions 522 may be a simple protruding protrusion shape, but differently, they may also be protrusions protruding from the front end of a cantilever-shaped structure.

[0181] A second inner stopper rib 524 may be formed along an edge of the second through hole 514' of the second base 514. The second inner stopper rib 524 may include a portion of the inner column stopper 518 and be annular as a whole. The second inner stopper rib 524 may be formed to be orthogonal to the second base 514. The second inner stopper rib 524 may protrude toward the third base 515.

[0182] A plurality of second outer stopper protrusions 526 may be formed along the outer edge of the second base 514. The second outer stopper protrusions 526 may be formed protrudingly on the second base 514. The second outer stopper protrusions 526 can prevent the filter 530 from arbitrarily detaching from the frame 510. However, the protrusion of the second outer stopper protrusions 526 should not make it difficult to install the filter 530 on the frame 510. Therefore, the protrusion of the second outer stopper protrusions 526 should be smaller than the protrusion of the second inner stopper rib 524. The second outer stopper protrusions 526 may be a simple protruding protrusion shape, but differently, may also be a protrusion protruding from the front end of a cantilever-shaped structure.

[0183] A third inner retaining member rib 527 may be formed along the edge of the third through hole 515' of the third base 515. The third inner retaining member rib 527 may include a portion of the inner column retaining member 518 and be annular as a whole.

The third inner retaining member rib 527 may protrude toward the first base 512 and the second base 514, respectively.

[0184] A plurality of third outer stopper protrusions 528 may be formed along the outer edge of the third base 515. The third outer stopper protrusions 528 may be formed protrudingly on the third base 515. The third outer stopper protrusions 528 can prevent the filter 530 from arbitrarily detaching from the frame 510. However, the protrusion degree of the third outer stopper protrusions 528 should not make it difficult to install the filter 530 on the frame 510. Therefore, the protrusion degree of the third outer stopper protrusions 528 should be less than the protrusion degree of the third inner stopper rib 527. The third outer stopper protrusions 528 may be a simple protruding protrusion shape, but differently from this, it may also be a protrusion protruding from the front end of a cantilever-shaped structure. Some of the third outer stopper protrusions 528 may protrude toward the first base 512, and some may protrude toward the second base 514.

[0185] The filter 530 is a component for filtering various pollutants such as dust, odor, and viruses. The filter 530 is installed on the frame 510 for use, and the frame 510 can be installed with a plurality of filters 530. In the present embodiment, 6 filters 530 are used, 3 per layer. Each of the filters 530 can have the same shape. The filter 530 is located in the area where air passes through the filter assembly 501 of the present invention, and can be cylindrical in shape as a whole. That is, in the present embodiment, if 3 filters 530 are installed on the frame 510 in one layer, the whole can be cylindrical in shape.

[0186] In this embodiment, the structure of the filter 530 is the same as that in the above-described embodiment. Fig.11 The embodiment shown in FIG. 5 is the same. However, based on the drawings, the height of the filter 530 is relatively low. Therefore, in this embodiment, the description of the specific structure of the filter 530 is omitted, and the corresponding components are given the reference numerals of the 500 series. For example, the first filter part 531, the third filter part 533, the first decorative plate 534, the second decorative plate 536, the handle 542, etc. are shown in the figure.

[0187] Secondly, Figure 37 to Figure 39 Another embodiment of the present invention is shown in FIG. Filter assembly 601 of this embodiment may include a frame 610 and a plurality of filters 630 .

[0188] The frame 610 may form a skeleton of the filter assembly 601. The filter 630 may be mounted or removed from the frame 610. The first base 612, the second base 614, and the third base 615 may be arranged in parallel in sequence at a predetermined interval on the frame 610. The first base 612 and the third base 615 may be arranged opposite to each other, and the third base 615 and the second base 614 may be arranged opposite to each other.

[0189] The first base 612, the second base 614 and the third base 615 can be respectively configured as annular plates. A first through hole 612' can be formed through the first base 612, a second through hole 614' can be formed through the second base 614, and a third through hole 615' can be formed through the third base 615.

[0190] A plurality of connecting posts 616 may be provided to connect the first base 612, the second base 614, and the third base 615 at predetermined intervals. In this embodiment, four connecting posts 616 extend side by side to connect the first base 612, the second base 614, and the third base 615 to each other. In this embodiment, the connecting posts 616 may be located between the inner edge and the outer edge of the first base 612, the second base 614, and the third base 615 to connect them to each other. In this embodiment, the four connecting posts 616 may be arranged at 90-degree intervals in the circular area formed by the bases 612, 614, and 615.

[0191] The connecting column 616 may be orthogonally connected to the first base 612, the second base 614, and the third base 615, respectively. The connecting column 616 is in the shape of a plate having a predetermined width. The connecting column 616 is preferably as thin as possible. This is because if the thickness of the connecting column 616 increases, the area through which air passes through the filter 630 becomes narrower.

[0192] The connecting column 616 may be provided with an inner column stopper 618. The connecting column 616 may be provided with the inner column stopper 618 on one side in the width direction. The inner column stopper 618 may be exposed to a space formed by penetrating the center of the filter assembly 601. The inner column stopper 618 may extend along one side in the width direction of the connecting column 616 corresponding to the first through hole 612', the second through hole 614', and the third through hole 615'. The inner column stopper 618 may be formed as a whole and continuously. However, as long as there is no problem in fixing the filter 630, the inner column stopper 618 may be formed intermittently. That is, the inner column stopper 618 may also be separated into a plurality of parts.

[0193] The cross section including the connecting column 616 and the inner column locking piece 618 may be in a “T” shape. The inner column locking piece 618 may lock the corresponding edge of the filter 630 so that the filter 630 can be firmly disposed on the frame 610 .

[0194] In this embodiment, four connecting posts 616 are arranged at intervals of 90 degrees, which can divide the area where the filter 630 is arranged into four areas, so that the filter 630 can cover an area of ​​90 degrees.

[0195] Some of the connecting posts 616 may have outer post stoppers 619. Fig.39 As shown, two of the four connecting columns 616 are provided with outer column stoppers 619. The outer column stoppers 619 are provided at two connecting columns 616 facing each other. Here, since the two connecting columns 616 provided with the outer column stoppers 619 are provided with inner column stoppers 618, the entire structure can have an "H"-shaped cross section.

[0196] The direction in which the outer column stopper 619 protrudes from the connecting column 616 may be the direction in which the filter 630 is mounted on or separated from the frame 610. Therefore, in the connecting column 616 having the outer column stopper 619, the baffle 640 of the filter 630 moves toward a direction approaching the surface of the connecting column 616 or away from the surface of the connecting column 616.

[0197] A first inner stopper rib 620 may be formed along an edge of the first through hole 612' of the first base 612. The first inner stopper rib 620 may include a portion of the inner column stopper 618 and be annular as a whole. The first inner stopper rib 620 may be formed to be orthogonal to the first base 612. The first inner stopper rib 620 may protrude toward the third base 615.

[0198] A plurality of first outer stopper protrusions 622 may be formed along the outer edge of the first base 612. The first outer stopper protrusions 622 may be formed protrudingly on the first base 612. The first outer stopper protrusions 622 can prevent the filter 630 from arbitrarily detaching from the frame 610. However, the protrusion degree of the first outer stopper protrusions 622 should not make it difficult to install the filter 630 on the frame 610. Therefore, the protrusion degree of the first outer stopper protrusions 622 should be less than the protrusion degree of the first inner stopper rib 620. That is, the height of the first outer stopper protrusions 622 is lower than that of the first inner stopper rib 620. The first outer stopper protrusions 622 may be a simple protruding protrusion shape, but differently, it may also be a protrusion protruding from the front end of a cantilever-shaped structure.

[0199] On the other hand, a post hook 623 may be formed in the connecting post 616 without the outer post stopper 619. The post hook 623 is cantilevered and has a protruding portion at the front end, so as to stop one side of the filter 630. The post hook 623 may play the same role as the first outer protrusion 622.

[0200] A second inner stopper rib 624 may be formed along an edge of the second through hole 614' of the second base 614. The second inner stopper rib 624 may include a portion of the inner column stopper 618 and be annular as a whole. The second inner stopper rib 624 may be formed to be orthogonal to the second base 614. The second inner stopper rib 624 may protrude toward the third base 615.

[0201] A plurality of second outer stopper protrusions 626 may be formed along the outer edge of the second base 614. The second outer stopper protrusions 626 may be formed protrudingly on the second base 614. The second outer stopper protrusions 626 can prevent the filter 630 from being arbitrarily separated from the frame 610. However, the protrusion of the second outer stopper protrusions 626 should not make it difficult to install the filter 630 on the frame 610. Therefore, the protrusion of the second outer stopper protrusions 626 should be smaller than the protrusion of the second inner stopper rib 624. The second outer stopper protrusions 626 may be a simple protruding protrusion shape, but differently, may also be a protrusion protruding from the front end of a cantilever-shaped structure.

[0202] A third inner retaining member rib 627 may be formed along the edge of the third through hole 615' of the third base 615. The third inner retaining member rib 627 may include a portion of the inner column retaining member 618 and be annular as a whole. The third inner retaining member rib 627 may be formed to be orthogonal to the third base 615. The third inner retaining member rib 627 may protrude toward the first base 612 and the second base 614, respectively.

[0203] A plurality of third outer stopper protrusions 628 may be formed along the outer edge of the third base 615. The third outer stopper protrusions 628 may be formed protrudingly on the third base 615. The third outer stopper protrusions 628 can prevent the filter 630 from arbitrarily detaching from the frame 610. However, the protrusion degree of the third outer stopper protrusions 628 should not make it difficult to install the filter 630 on the frame 610. Therefore, the protrusion degree of the third outer stopper protrusions 628 should be less than the protrusion degree of the third inner stopper rib 627. The third outer stopper protrusions 628 may be a simple protruding protrusion shape, but differently from this, it may also be a protrusion protruding from the front end of a cantilever-shaped structure. Some of the third outer stopper protrusions 628 may protrude toward the first base 612, and some may protrude toward the second base 614.

[0204] The filter 630 is a component for filtering various pollutants such as dust, odor, and viruses. The filter 630 is installed on the frame 610 for use, and the frame 610 can be installed with a plurality of filters 630. In the present embodiment, 8 filters 630 are used, 4 per layer. Each of the filters 630 can have the same shape. The filter 630 is located in the area where air passes through the filter assembly 601 of the present invention, and can be cylindrical in shape as a whole. That is, in the present embodiment, if 4 filters 630 are installed on the frame 610 in one layer, the whole can be cylindrical in shape.

[0205] In this embodiment, the filter 630 is constructed similarly to the above-described embodiment. Fig.19 The embodiment shown in FIG. 6 is the same. However, based on the attached drawings, the height of the filter 630 is relatively low. Therefore, in this embodiment, the description of the specific structure of the filter 630 is omitted, and the corresponding components are given the reference numerals of the 600 series. For example, the first filter part 631, the third filter part 633, the first decorative plate 634, the second decorative plate 636, the handle 642, etc. are shown in the attached drawings.

[0206] Secondly, Figure 40 to Figure 422 shows a filter assembly 701 of another embodiment of the present invention. The filter assembly 701 of this embodiment is composed of a plurality of filters 730, 730'. The filters 730, 730' are respectively cylindrical in shape, and by stacking these filters 730, 730', the filter assembly 701 can be formed in a cylindrical shape as a whole.

[0207] The filters 730 and 730' are identical in structure except for the coupling protrusions and recesses 740 and 740' described below. Therefore, the components of the filters 730 and 730' are denoted by the same reference numerals.

[0208] The filters 730 and 730' may also have a plurality of filter parts. In the illustrated embodiment, there are a first filter part 731, a second filter part 732, and a third filter part 733. These filter parts 731, 732, and 733 can filter different pollutants respectively. This has been fully described in the above embodiment, so the description is omitted.

[0209] The filter parts 731, 732, 733 may be located between the first decorative plate 734 and the second decorative plate 736. The filter parts 731, 732, 733 are respectively concentric cylindrical shapes, and the first decorative plate 734 and the second decorative plate 736 may be configured as annular plates having a shape corresponding to the cross-sectional shape of the filter parts 731, 732, 733.

[0210] End ribs 737 are provided around the edges of the first decorative plate 734 and the second decorative plate 736. The filter parts 731, 732, 733 are fixedly arranged between the end ribs 737. The first decorative plate 734 is located at one end of the filter parts 731, 732, 733, and the second decorative plate 736 is located at the other end of the filter parts 731, 732, 733.

[0211] The first decorative plate 734 and the second decorative plate 736 may have spacer ribs 738. The spacer ribs 738 are formed on the surfaces of the first decorative plate 734 and the second decorative plate 736 facing each other, respectively, so as to form a predetermined gap between the first filter part 731 and the second filter part 732.

[0212] On the other hand, Fig.42As shown, a first coupling protrusion 740 may be formed on the outer surface of the first decorative plate 734 of the filter 730, and a second coupling protrusion 740' may be formed on the outer surface corresponding to the first decorative plate 736 of the filter 730'. Here, the first coupling protrusion 740 is a protruding annular rib, and the second coupling protrusion 740' is an annular groove. The filters 730 and 730' are combined into one body by combining the first coupling protrusion 740 and the second coupling protrusion 740', so as to form a filter assembly 701.

[0213] For reference, the first convex-shaped coupling concave-convex 740 and the concave-shaped second coupling concave-convex 740' may be formed at opposite positions to each other. That is, the convex annular rib, i.e., the first coupling concave-convex 740, may be formed on the second decorative plate 736 of the filter 730', and the annular groove, i.e., the second coupling concave-convex 740', may be formed on the first decorative plate 734 of the filter 730.

[0214] Hereinafter, a case where the filter assembly according to the embodiment of the present invention having the above-described structure is used will be described in detail.

[0215] Figure 1 The filter assembly 1 of the illustrated embodiment is configured by mounting two filters 30 on a frame 10 , and the two filters 30 are attachable and detachable in opposite directions relative to the frame 10 .

[0216] like Fig. 9 As shown, the filter 30 can be installed on or removed from the frame 10 along the direction of arrow A. The filter 30 moves along the protruding direction of the inner column stopper 18 and the outer column stopper 19. This is to prevent the inner column stopper 18 and the outer column stopper 19 from interfering with the filter 30 during the installation and removal process of the filter 30. When separating the filter 30 from the frame 10, the user can just grab the handle 40 and apply force.

[0217] like Figure 1 As shown, if two filters 30 are installed on the frame 10 to produce a cylindrical filter assembly 1, this can be set in an air purifier for use. For example, the upper or lower part of the through-portion formed by passing through the center of the filter assembly 1 has a fan motor (not shown), so when suction is provided, the external air passes through the filter parts 31, 32, and 33 of the filter 30 from the outer surface of the filter assembly 1 and the pollutants are filtered. At this time, the filter parts 31, 32, and 33 can filter specific pollutants according to their respective functions. The air after the pollutants are filtered can flow from the center of the filter assembly 1 to the side with the fan motor and be delivered to the desired position.

[0218] If the filter assembly 1 is used for a certain period of time, the filter 30 is contaminated and needs to be cleaned or replaced. However, it is possible that not all of the two filters 30 are contaminated, only one of them is contaminated, or relatively more contaminated. In this case, the relatively more contaminated filter 30 can be removed from the frame 10 for cleaning or replacement.

[0219] Secondly, Fig.11 In the embodiment shown, there are three filters 130. These three filters 130 are arranged one for each interval corresponding to 120 degrees in the 360 ​​degree area of ​​the frame 110. Fig.18 As shown, the filter 130 can be pulled from the frame 110 along the centrifugal direction of the frame 110 using the handle 142. Here, the connecting column 116 has only the inner column stopper 118, and there is no structure on the opposite side, so that the filter 130 can be smoothly installed and removed.

[0220] exist Fig.19 In the embodiment shown, there are four filters 230. These four filters 230 are located in intervals corresponding to 90 degrees in the 360-degree area of ​​the frame 210. Fig.25 As shown, in the connection column 216 having the inner column stopper 218 and the outer column stopper 219, it is sufficient to apply force to the filter 230 to move the filter 230 away from and toward the connection column 216. For this purpose, the handle 242 of this embodiment is located at a portion corresponding to the middle edge in the height direction of the filter 230. In this way, if the filter 230 moves, the baffle 240 of the filter 230 at the opposite side end of the filter 230 moves along the surface of the connection column 216, so that the filter 230 can be separated from the frame 210. When installing the filter 230 on the frame 210, it is sufficient to move the filter 230 in the opposite direction to the above.

[0221] exist Fig.26 In the embodiment shown, the filter 330 formed in a cylindrical shape is installed to form two layers on the frame 310. Fig.26 As a reference, any one of the filters 330 layered in the height direction of the filter assembly 301 can be separated and replaced or cleaned. In this embodiment, the filter 330 can move along the extending direction of the connecting column 316 arranged at 180 degree intervals in the connecting column 316. This action can be Fig.30 Seen in.

[0222] Secondly, in Fig.31 In the embodiment shown, the filter 430 is formed in two layers on the frame 410, and there are two filters 430 on each layer. Figure 1As in the illustrated embodiment, the filter 430 is mounted on or removed from the frame 410. Therefore, one or more filters can be separated from the four filters 430 for replacement or cleaning.

[0223] exist Fig.34 In the embodiment shown, the filters 530 are arranged in two layers on the frame 510, with three filters 530 on each layer. Therefore, a total of six filters 530 can be individually mounted on or removed from the frame 510. More than one of the six filters 530 can be separated for replacement or cleaning. Fig.11 The filter 530 is installed and removed as in the illustrated embodiment.

[0224] exist Fig.37 In the embodiment shown, the filters 630 form two layers on the frame 610, and there are four filters 630 in each layer. Therefore, a total of eight filters 630 can be individually installed on the frame 610 or removed from the frame 610. More than one filter can be separated from these eight filters 630 for replacement or cleaning. Fig.19 As in the illustrated embodiment, the filter 630 is mounted and removed.

[0225] On the other hand, Fig.40 In the illustrated embodiment, two cylindrical filters 730, 730' are stacked to form the filter assembly 701. Therefore, the two filters 730, 730' can be separated and replaced or cleaned by simply releasing the first and second coupling projections and recesses 740 and 740' that couple the two filters 730, 730'.
