Description

filter

[0001] The present invention relates to a filter.

[0002] An air purifier is a device that improves indoor air quality by sucking in indoor air contaminated with dust and other pollutants, purifying it, and then discharging the purified air into the room.

[0003] Typically, an air purifier includes a filter that captures pollutants contained in the air and purifies the air, a blower fan that provides suction power to draw in indoor air and discharges the air purified by the filter back into the room, and a housing in which various parts are installed.

[0004] As air purifiers are recently manufactured with a cylindrical appearance, the filters installed in the air purifiers are also manufactured in a cylindrical shape.

[0005] The filter comprises a cylindrical member having a plurality of activated carbon filling chambers, and can provide a deodorizing function by allowing air to come into contact with activated carbon filled in the activated carbon filling chambers.

[0006] However, the cylindrical member has the problem that it is difficult to manufacture a structure that has multiple activated carbon charging chambers while implementing a cylindrical, curved shape, and that the manufacturing cost is high, resulting in low productivity.

[0010] The present invention aims to provide a filter including a plate having a plurality of activated carbon filling chambers that are easily deformed in shape.

[0011] According to one feature of the present invention, a filter comprises a plate having a plurality of activated carbon charging chambers, wherein each of the activated carbon charging chambers forms an independent space, and one of the walls forming the space is shared with one of the walls of another activated carbon charging chamber and is integrally connected to each other, and the space has a corner portion by a portion where adjacent wall surfaces meet each other, and has a groove-shaped deformation portion crossing the portion where the corner portions of each of the spaces meet.

[0012] In addition, the first space and the second space are provided adjacent to each other and meet from the corner portion, and the deformation portion includes a first inclined portion formed on the upper portion of two wall surfaces forming the corner portion of the first space and a second inclined portion formed on the upper portion of two wall surfaces forming the corner portion of the second space.

[0013] In addition, the filter can be deformed into a round shape by meeting the first slope and the second slope so that they come close to each other.

[0014] In addition, the plurality of activated carbon charging chambers are provided in a square structure and are connected to each other as one body.

[0015] In addition, a thin section is provided at the lower part of the above-mentioned deformation section.

[0016] A filter according to the present invention comprises a plate having a plurality of activated carbon charging chambers, wherein each of the activated carbon charging chambers forms an independent space, and one of the walls forming the space is shared with one of the walls of another activated carbon charging chamber and is integrally connected to each other, and a groove-shaped deformation portion is formed across the wall surfaces facing in the width direction or length direction.

[0017] In addition, a plurality of the activated carbon charging chambers are provided with a honeycomb structure and are integrally connected to each other, and the honeycomb structure is a structure in which each of the activated carbon charging chambers has a hexagonal cross-sectional shape, and six vertices forming the hexagonal cross-sectional shape are shared as one of the vertices forming another hexagonal cross-sectional shape and are integrally connected.

[0018] Additionally, the deformation section cuts across the wall surface.

[0019] In addition, a thin section is provided at the lower part of the above-mentioned deformation section.

[0020] In addition, when one end and the other end of the plate are in contact with each other to form a cylindrical shape, there is no space between the activated carbon charging chambers.

[0021] The present invention provides a filter that can easily transform from a flat shape to a cylindrical shape by having a transforming portion, and that does not require a space between activated carbon charging chambers, thereby improving deodorizing performance by utilizing the entire area as an area capable of containing activated carbon.

[0040] Hereinafter, the width direction of the filter (100) described is the ±x direction indicated in the drawing, the length direction of the filter (100) is the ±y direction indicated in the drawing, and the thickness direction of the filter (100) is the ±z direction indicated in the drawing.

[0041] The filter (100) described below can be preferably deformed into a round shape and formed into a cylindrical filter.

[0042] FIG. 1 is a perspective view of a plate (10) of a first embodiment of a first embodiment provided in a filter (100) of the present invention, FIG. 2 is an enlarged view of a part of FIG. 1, FIG. 3 is a plan view of FIG. 1, and FIG. 4 is a side view of FIG. 1.

[0043] Referring to FIGS. 1 to 4, the plate (10) of the first embodiment of the first embodiment may be provided in a form having a length that is relatively longer in the width direction (±x direction) than in the length direction (±y direction).

[0044] The plate (10) of the first embodiment of the present invention has a plurality of activated carbon charging chambers (11). The activated carbon charging chambers (11) provide a space in which a certain amount of activated carbon (AC) in contact with air is charged.

[0045] The plate (10) of the first embodiment of the present invention is formed with a structure in which each activated carbon charging chamber (11) forms an independent space (SP), and one of the wall surfaces (WA) forming the space (SP) is shared with one of the wall surfaces (WA) of another activated carbon charging chamber (11) and is connected integrally.

[0046] In other words, the plate (10) of the first embodiment of the present invention has a structure in which a wall surface (WA) forming a space (SP) of one activated carbon charging chamber (11) is configured as a wall surface (WA) of another adjacent activated carbon charging chamber (11) to form another independent space (SP). Accordingly, in the plate (10) of the first embodiment of the present invention, a plurality of activated carbon charging chambers (11) are integrally connected through the wall surface (WA) shared by each other, so that no space exists between the plurality of activated carbon charging chambers (11).

[0047] The plurality of activated carbon charging chambers (11) are preferably provided with a honeycomb structure and can be integrally connected to each other. Alternatively, the plurality of activated carbon charging chambers (11) may be provided with a polygonal structure including a square structure, a triangular structure, an octagonal structure, or a circular structure.

[0048] A honeycomb structure is a structure in which six vertices forming a hexagonal cross-section shape are connected as one by sharing one of the vertices forming another hexagonal cross-section shape.

[0049] Accordingly, each activated carbon charging chamber (11) may be provided with a hexagonal column-shaped empty space having a hexagonal cross-sectional shape. Each activated carbon charging chamber (11) may have a space (SP) formed by six wall surfaces (WA). The six wall surfaces (WA) may be shared to function as the wall surfaces (WA) of another adjacent activated carbon charging chamber (11), thereby forming another independent space (SP).

[0050] Accordingly, the plate (10) of the first embodiment of the present invention is formed in a honeycomb structure in which a plurality of activated carbon charging chambers (11) share a wall surface (WA) with each other and are integrally connected while sharing six vertices forming a hexagonal cross-sectional shape.

[0051] The plate (10) of the first embodiment of the present invention is provided in a honeycomb structure and has activated carbon charging chambers (11) having a hexagonal cross-sectional shape arranged in a plurality of rows in the length direction (±y direction) and a plurality of columns in the width direction (±x direction).

[0052] Accordingly, in each activated carbon charging chamber (11), a plurality (six) of wall surfaces (WA) forming an independent space (SP) include a first wall surface (WA1) and a second wall surface (WA2) that are opposed in parallel in the longitudinal direction (±y direction). At this time, each of the first and second wall surfaces (WA1, WA2) is opposed in the longitudinal direction (±y direction) while being shared to form a space (SP) of a different activated carbon charging chamber (11).

[0053] The plate (10) of the first embodiment of the present invention has a deformation portion (TP) that crosses a plurality of activated carbon charging chambers (11). The deformation portion (TP) is formed in the shape of a groove that crosses the first and second wall surfaces (WA1, WA2) of each of the activated carbon charging chambers (11) that face each other in the longitudinal direction (±y direction) in the longitudinal direction (±y direction).

[0054] Specifically, the plate (10) of the first embodiment of the present invention is arranged in a form in which a plurality of activated carbon charging chambers (11) are arranged in the width direction (±x direction) and the length direction (±y direction), so that the first and second wall surfaces (WA1, WA2) of each activated carbon charging chamber (11) are aligned with a distance apart in the length direction (±y direction).

[0055] However, at least some of the plurality of activated carbon charging chambers (11) arranged in the width direction (±x direction) on the outer portion in the width direction (±x direction) may omit at least one of the first and second walls (WA1, WA2). In this case, the activated carbon charging chamber (11) in which at least one of the first and second walls (WA1, WA2) is omitted may be connected to the space (SP) of another activated carbon charging chamber (11) adjacent in the length direction (±y direction) to form an activated carbon charging chamber (11) having an octagonal structure and a relatively large space (SP). The activated carbon charging chamber (11) having an octagonal structure includes eight corners, the space (SP) is formed through eight wall surfaces (WA), and has an octagonal cross-sectional shape. The plate (10) of the first embodiment of the present invention alternately has activated carbon charging chambers (11) having an octagonal structure and activated carbon charging chambers (11) having a hexagonal structure on the outer portion in the width direction (±x direction), so that when deforming into a cylindrical shape, bending deformation can be more easily implemented on the outer portion in the width direction (±x direction). The plate (10) of the first embodiment of the present invention may be provided in a form in which activated carbon charging chambers (11) having a hexagonal structure are arranged in a plurality of rows and columns, share a wall surface (WA), and are integrally connected through the wall surface (WA).

[0056] In the drawing, at least a part of the second wall surface (WA2) of a plurality of activated carbon charging chambers (11) arranged in the outer portion in the width direction (±x direction) is omitted. Accordingly, in the outer portion in the width direction (±x direction), an activated carbon charging chamber (11) including the first and second wall surfaces (WA1, WA2) and having a relatively small space (SP) of a hexagonal structure, and an activated carbon charging chamber (11) having a relatively small space (SP) by omitting the second wall surface (WA2) are connected to each other, so that an activated carbon charging chamber (11) having a relatively large space (SP) of an octagonal structure can be arranged alternately based on the width direction (±x direction).

[0057] In other words, the plate (10) of the first embodiment of the present invention has a form in which an activated carbon charging chamber (11) having an empty space (SP) inside in a hexagonal structure on the outer portion in the width direction (±x direction) and an activated carbon charging chamber (11) having an empty space (SP) inside in an octagonal structure are alternately arranged based on the width direction (±x direction). In the octagonal structure, the first wall surfaces (WA1) may face each other in the length direction (±y direction).

[0058] In the central portion surrounded by the outer portion of the plate (10) of the first embodiment of the present invention, a plurality of activated carbon charging chambers (11) having a hexagonal structure are arranged integrally connected through the wall surfaces (WA) by six wall surfaces (WA), including the first and second wall surfaces (WA1, WA2).

[0059] A plurality of deformation portions (TP) are provided corresponding to a plurality of columns of activated carbon charging chambers (11) aligned in the width direction (±x direction), and are formed across a plurality of rows of activated carbon charging chambers (11) aligned in the length direction (±y direction) in the length direction (±y direction). Accordingly, deformation portions (TP) are formed on the walls of the activated carbon charging chambers (11) arranged in a plurality of rows and columns (first wall surfaces (WA1) facing each other in an activated carbon charging chamber (11) having an octagonal structure, and first and second wall surfaces (WA1, WA2) facing each other in an activated carbon charging chamber (11) having a hexagonal structure).

[0060] In other words, the deformation portion (TP) is formed on a wall surface (WA) that crosses the plurality of activated carbon charging chambers (11) in the longitudinal direction (±y direction) and faces the entire plurality of activated carbon charging chambers (11) in the longitudinal direction (±y direction).

[0061] The deformation portion (TP) is formed in a shape that cuts across the wall surface (WA) in the thickness direction (±z direction). Referring to Fig. 2, the deformation portion (TP) is formed on each of the first and second wall surfaces (WA1, WA2), and the deformation portion (TP) can be formed by cutting the first and second wall surfaces (WA1, WA2) from the top to the bottom of the first and second wall surfaces (WA1, WA2) based on the thickness direction (±z direction). Accordingly, the deformation portion (TP) can be formed by a cut portion formed by cutting each of the first and second wall surfaces (WA1, WA2).

[0062] Accordingly, the portion where the first and third wall surfaces (WA1, WA3) meet by the deformation portion (TP) to form the corner portion (EG) is cut to form a V-shaped cross-sectional shape, and the upper portions in the thickness direction (±z direction) of the first and third wall surfaces (WA1, WA3) are provided in a cut-off state. In addition, the portion where the second and fourth wall surfaces (WA2, WA4) meet by the deformation portion (TP) to form the corner portion (EG) is cut to form a V-shaped cross-sectional shape, and the upper portions in the thickness direction (±z direction) of the second and fourth wall surfaces (WA2, WA4) are provided in a cut-off state.

[0063] The deformation portion (TP) can be formed in a form that completely cuts the wall surface (WA) in the thickness direction (±z direction), or can be formed in a form that at least partially cuts the wall surface (WA) in the thickness direction (±z direction) to provide a thin-wall portion (TW) at the bottom of the deformation portion (TP).

[0064] In the drawing, as an example, the wall surface (WA) is shown as having a deformation portion (TP) and a thin-wall portion (TW) formed by cutting at least a portion of the wall surface (WA) in the thickness direction (±z direction).

[0065] The deformation portion (TP) can be formed to have a constant width direction (±x direction) dimension from the top to the bottom in the thickness direction (±z direction). In this case, the deformation portion (TP) can be formed in a constant shape, for example, a 'U' shape, with the width direction (±x direction) dimension between the first cutting surface (IC1) and the second cutting surface (IC2) provided by the cutting portion being the same dimension.

[0066] The deformation portion (TP) may preferably be formed in a 'V' shape in which the width direction (±x direction) dimension gradually decreases from the top to the bottom in the thickness direction (±z direction). In this case, the deformation portion (TP) may have a shape in which the width direction (±x direction) dimension between the first cutting surface (IC1) and the second cutting surface (IC2) provided by the cut portion gradually decreases from the top to the bottom in the thickness direction (±z direction). However, the shape of the deformation portion (TP) is not limited to a 'U' shape or a 'V' shape, and may include all shapes that can be formed by cutting.

[0067] The deformation portion (TP) is preferably formed to have a smaller dimension than the thickness direction (±z direction) dimension of the wall surface (WA). Accordingly, the deformation portion (TP) may be formed by cutting the wall surface (WA) in the thickness direction (±z direction), but may be formed in a form that does not completely divide the wall surface (WA).

[0068] The plate (10) of the first embodiment of the present invention has a thickness direction (±z direction) dimension of a deformation portion (TP) smaller than a thickness direction (±z direction) dimension of a wall surface (WA), and has a thin-wall portion (TW) formed through a portion that is not cut at the lower portion of the deformation portion (TP). The thin-wall portion (TW) may be a portion formed by a difference between a thickness direction (±z direction) dimension of the wall surface (WA) and a thickness direction (±z direction) dimension of the deformation portion (TP). Accordingly, the thin-wall portion (TW) has a thickness direction (±z direction) dimension equal to the difference between the thickness direction (±z direction) dimension of the wall surface (WA) and the thickness direction (±z direction) dimension of the deformation portion (TP). The thickness direction (±z direction) dimension of the thin-wall portion (TW) is smaller than the thickness direction (±z direction) dimension of the deformation portion (TP).

[0069] The plate (10) of the first embodiment of the present invention can be more easily deformed into a cylindrical shape through a deformation portion (TP) that cuts the wall surface (WA) facing in the longitudinal direction (±y direction) of each activated carbon charging chamber (11) across a plurality of activated carbon charging chambers (11).

[0070] Specifically, the plate (10) of the first embodiment of the present invention is deformed into a cylindrical shape having an empty space inside by contacting one end and the other end in the width direction (±x direction).

[0071] FIG. 5 is a perspective view of a state in which a plate (10) of the first embodiment of the present invention in the form of a flat plate is deformed into a cylindrical shape by contacting one end and the other end in the width direction (±x direction) of the plate (10) of the first embodiment of the present invention, and FIG. 6 is a plan view of FIG. 5.

[0072] Referring to FIGS. 5 and 6, the plate (10) of the first embodiment of the present invention is deformed into a cylindrical shape by contacting one end and the other end and bending the area between the one end and the other end. The plate (10) of the first embodiment of the present invention can be fixedly connected by bonding the contact interface between the one end and the other end with an adhesive material or by using a hook. The method for fixing and connecting the one end and the other end of the plate (10) of the first embodiment of the present invention is not limited thereto.

[0073] The entire area of ​​the plate (10) of the first embodiment of the present invention, which has a plurality of activated carbon charging chambers (11), is bent and deformed by a force that contacts and deforms one end and the other end of the plate (10) of the first embodiment of the present invention. The plate (10) of the first embodiment of the present invention can preferably be bent and deformed in a form in which a thin-walled portion (TW) is positioned on the outer side in the thickness direction (±z direction) and a deformed portion (TP) is positioned on the inner side in the thickness direction (±z direction).

[0074] More specifically, the plate (10) of the first embodiment of the present invention has a thin-walled portion (TW) at the bottom in the thickness direction (±z direction) and a deformation portion (TP) at the top in the thickness direction (±z direction) in a flat plate shape. Referring to FIGS. 1, 2, and 4, in the plate (10) of the first embodiment of the present invention in the flat plate shape in which no force causing bending deformation is generated, the deformation portion (TP) is provided in a shape in which the width direction (±x direction) dimension between the first and second cutting surfaces (IC1, IC2) becomes smaller from the top to the bottom in the thickness direction (±z direction).

[0075] The plate (10) of the first embodiment of the present invention can undergo bending deformation on the xz plane of Fig. 1 by a force that deforms the flat shape by contacting one end and the other end in the width direction (±x direction). At this time, the plate (10) of the first embodiment of the present invention is in a state in which the width direction (±x direction) dimension is relatively reduced by the deformation portion (TP) that cuts the wall surface (WA) of each of the plurality of activated carbon charging chambers (11).

[0076] In other words, the plate (10) of the first embodiment of the present invention has a deformation portion (TP) that cuts the wall surface (WA), and thus has a relatively smaller overall width direction (±x direction) dimension compared to a structure having an activated carbon charging chamber (11) having a wall surface (WA) that is not cut by the deformation portion (TP). Accordingly, the plate (10) of the first embodiment of the present invention can be more easily bent and deformed from a flat plate shape into a cylindrical shape.

[0077] The plate (10) of the first embodiment of the present invention is preferably made of a material that is easily bendable and has a deformation portion (TP) that reduces the width direction (±x direction) dimension of the entire plate (10) of the first embodiment of the present invention in the form of a cut in the wall surface (WA) of the activated carbon charging chamber (11), thereby enabling it to be easily transformed from a flat plate shape to a cylindrical shape.

[0078] Referring to FIGS. 5 and 6, in the plate (10) of the first embodiment of the present invention having a cylindrical shape, the deformation portion (TP) is formed such that the upper portion in the thickness direction (±z direction) is folded so that the upper portions in the thickness direction (±z direction) of each of the first and second cutting surfaces (IC1, IC2) are in contact. In this way, the plate (10) of the first embodiment of the present invention can be easily bent into a cylindrical shape when the deformation portion (TP) is folded when it is transformed from a flat plate shape into a cylindrical shape.

[0079] The plate (10) of the first embodiment of the present invention has a plurality of activated carbon charging chambers (11) that are integrally connected to each other while sharing at least one wall surface (WA). Therefore, in the plate (10) of the first embodiment of the present invention, there is no space between the plurality of activated carbon charging chambers (11) in a cylindrical configuration.

[0080] The plate (10) of the first embodiment of the present invention has a deformation portion (TP) that crosses a plurality of activated carbon charging chambers (11), so that it can be easily bent into a cylindrical shape without providing a separate space between the plurality of activated carbon charging chambers (11) to allow for the bending deformation into a cylindrical shape. Accordingly, the plate (10) of the first embodiment has a structure in which the plurality of activated carbon charging chambers (11) share at least one wall surface (WA) and are integrally connected to each other.

[0081] In addition, the plate (10) of the first embodiment of the present invention may have the same area as the entire area of ​​the plate (10) of the first embodiment and the area of ​​the charging chamber area (AF) having a plurality of activated carbon charging chambers (11).

[0082] In other words, the plate (10) of the first embodiment of the present invention has a structure in which a plurality of activated carbon charging chambers (11) are integrally connected without a space between them. Therefore, the plate (10) of the first embodiment of the present invention can have a greater number of activated carbon charging chambers (11) than a structure in which a separate space is provided between a plurality of activated carbon charging chambers (11) in consideration of bending deformation in the same total area. This allows the entire area of ​​the plate (10) of the first embodiment to be utilized as an area capable of providing activated carbon (AC), thereby further improving the deodorizing performance of the plate (10) of the first embodiment.

[0083] Figures 7a and 7b are schematic diagrams illustrating a process of providing activated carbon (AC) in a plurality of activated carbon charging chambers (11).

[0084] The plate (10) of the first embodiment of the present invention has a first mesh net (12) bonded to at least one surface in the thickness direction (±z direction) in a flat shape. Referring to Fig. 7a, the plate (10) of the first embodiment preferably has the first mesh net (12) on the outside of the thin-walled portion (TW) in the thickness direction (±z direction), so that the first mesh net (12) can be bonded to the outside in the thickness direction (±z direction) of the plate (10) of the first embodiment. Through this, at least one of the one-side opening and the other-side opening in the thickness direction (±z direction) of the plurality of activated carbon charging chambers (11) is closed by the first mesh net (12). In Fig. 7a, the first mesh net (12) closes one-side opening located close to the thin-walled portion (TW) and is bonded to the outside (lower part) in the thickness direction (±z direction) of the plate (10) of the first embodiment.

[0085] Then, activated carbon (AC) is filled into the space (SP) of each activated carbon charging chamber (11) through an open other-side opening located on the inner side (upper side in the flat plate form) in the thickness direction (±z direction) of the plate (10) of the first embodiment of the present invention.

[0086] The activated carbon (AC) may be provided so that its width direction (±x direction) dimension is larger than the width direction (±x direction) dimension of the deformation portion (TP). Accordingly, the activated carbon (AC) may not escape outside the activated carbon charging chamber (11) through the deformation portion (TP) while being provided in the activated carbon charging chamber (11).

[0087] The plate (10) of the first embodiment of the present invention fills each of a plurality of activated carbon charging chambers (11) with activated carbon (AC), and then functions as an activated carbon (AC) inlet and closes the other side opening that is open. The other side opening is closed by a second mesh net (13). The second mesh net (13) is attached to the inner side (upper side in the flat plate shape) of the plate (10) of the first embodiment in the thickness direction (±z direction) to close the other side opening.

[0088] The connection between the plate (10) of the first embodiment of the present invention and the first and second mesh nets (12, 13) can be achieved by a material having adhesive force. In this case, the first mesh net (12) can be fixedly connected to the plate (10) of the first embodiment by a material having adhesive force applied to one surface in the thickness direction (±z direction) of the wall surface (WA) of each activated carbon charging chamber (11). In addition, the second mesh net (13) can be fixedly connected to the plate (10) of the first embodiment by a material having adhesive force applied to the other surface in the thickness direction (±z direction) of the wall surface (WA) of each activated carbon charging chamber (11). However, the method of fixedly connecting the plate (10) of the first embodiment and the first and second mesh nets (12, 13) is not limited thereto.

[0089] The plate (10) of the first embodiment of the present invention is bent and deformed into a cylindrical shape while filling each of a plurality of activated carbon charging chambers (11) with activated carbon (AC) and closing each of one side opening and the other side opening of each of the plurality of activated carbon charging chambers (11) by the first and second mesh nets (12, 13).

[0090] The plate (10) of the first embodiment of the present invention can close the open cylindrical internal empty space by closing one opening and the other opening in the longitudinal direction (±y direction) of the cylinder in a cylindrical state in which the first and second mesh nets (12, 13) are fixedly connected. The closing member that closes the one opening and the other opening of the cylinder can be made of a mesh material, can be a material having relatively high strength, and can be the same material as the material constituting the plate (10) of the first embodiment. The material of the closing member is not limited thereto.

[0091] Then, the plate (10) of the first embodiment of the present invention may be combined with a filter member (not shown) for filtering fine particles on its outer surface. The filter member covers and surrounds the plate (10) of the first embodiment from the outside. Accordingly, the plate (10) of the first embodiment may be provided in a state where it is not exposed to the outside. The filter member may preferably be composed of a HEPA filter.

[0092] In the description referring to FIGS. 5 to 7b, the plate (10) of the first embodiment of the present invention is described as having a cylindrical shape in which a deformation portion (TP) is positioned on the inner side in the thickness direction (±z direction) and a thin portion (TW) is provided on the outer side. However, the shapes of the deformation portion (TP) and the thin portion (TW) based on the thickness direction (±z direction) are not limited thereto. The plate (10) of the first embodiment of the present invention may also be configured in a cylindrical shape in which a thin portion (TW) is positioned on the inner side in the thickness direction (±z direction) and a deformation portion (TP) is positioned on the outer side.

[0093] Fig. 8 is a schematic diagram illustrating a modified example of the plate (10) of the first embodiment of the present invention having a deformation portion (TP). Fig. 8 illustrates a plan view of the cylindrical plate (10) of the first embodiment.

[0094] The deformation example has an outer deformation portion (OT) having a dimension smaller than the thickness direction (±z direction) dimension of the deformation portion (TP) on the outer side (lower side in the plate shape) in the thickness direction (±z direction), and has a deformation portion (TP) on the inner side (upper side in the plate shape) in the thickness direction (±z direction) at a position where the center lines of the outer deformation portion (OT) are misaligned so as not to overlap with the center lines of the outer deformation portion (OT).

[0095] In other words, the deformation portion (TP) and the outer deformation portion (OT) are not adjacent to each other in the width direction (±x direction) but are located diagonally to each other in a zigzag shape. Accordingly, the deformation portion (TP) is provided on the inner side (upper side in a flat plate shape) in the thickness direction (±z direction) diagonally of the outer deformation portion (OT), and the outer deformation portion (OT) is provided on the outer side (lower side in a flat plate shape) in the thickness direction (±z direction) diagonally of the deformation portion (TP).

[0096] The outer deformation portion (OT) may be provided in a form that cuts across the wall surface (WA) facing in the longitudinal direction (±y direction) of a plurality of activated carbon charging chambers (11).

[0097] An example of a deformation is an outer deformation portion (OT) provided between two adjacent deformation portions (TP), but the deformation portions (TP) and the outer deformation portion (OT) are located in opposite directions with respect to the thickness direction (±z direction). Accordingly, the deformation portion (TP) is provided on the inner side (upper side in a flat plate shape) in the thickness direction (±z direction), and the outer deformation portion (OT) is provided on the outer side (lower side in a flat plate shape) in the thickness direction, but they are provided in a zigzag shape and are located diagonally from each other so that their center lines do not overlap.

[0098] An example of deformation is that when bending deformation from a flat shape to a cylindrical shape occurs through a deformation portion (TP) on the inside (upper in a flat shape) in the thickness direction (±z direction), deformation on the inside in the thickness direction (±z direction) can be more easily performed, and on the outside (lower in a flat shape) in the thickness direction (±z direction) can be more easily performed through an outer deformation portion (OT) on the outside (lower in a flat shape).

[0099] The plate (10) of the first embodiment of the present invention may have a more diverse shape of the deformation portion (TP).

[0100] FIGS. 9a to 14b are schematic diagrams illustrating various examples of a deformation portion (TP) formed on a plate (10) of the first embodiment of the present invention.

[0101] Figure 9a is a first embodiment of the invention in which the first and second cutting surfaces (IC1, IC2) are parallel to each other but are inclined obliquely to one side in the width direction (±x direction).

[0102] In the first embodiment, the first cutting surface (IC1) is formed obliquely in one direction (left side in the drawing of Fig. 9a) in the width direction (±x direction), and the second cutting surface (IC2) is formed obliquely in the same direction as the first cutting surface. Therefore, the first embodiment has an 11-shape (' / ' shape) that is obliquely inclined to one side in the width direction (±x direction) in the cross-sectional shape based on the width direction (±x direction). In other words, the first embodiment is formed by cutting the wall surface (WA) in the thickness direction (±z direction) so as to have an 11-shape obliquely inclined to one side in the width direction (±x direction).

[0103] Figure 9b is a first-second embodiment having protrusions (PJ, PJ') and concave portions (DT, DT') on the first and second cutting surfaces (IC1, IC2), respectively.

[0104] Embodiment 1-2 has a protrusion (PJ) protruding in the width direction (±x direction) on the first cutting surface (IC1) and a concave portion (DT) that is stepped in the length direction (±y direction) from the protrusion (PJ). Embodiment 1-2 has a concave portion (DT') corresponding to the protrusion (PJ) of the first cutting surface (IC1) on the second cutting surface (IC2) and a protrusion (PJ') corresponding to the concave portion (DT) of the first cutting surface (IC1).

[0105] Accordingly, in the first and second embodiments, the first and second cutting surfaces (IC1, IC2) are formed to face each other in the width direction (±x direction), and the concave portion (DT) of the first cutting surface (IC1) and the protrusion (PJ') of the second cutting surface (IC2) correspond to each other, and the protrusion (PJ) of the first cutting surface (IC1) and the concave portion (DT') of the second cutting surface (IC2) correspond to each other.

[0106] In the plate (10) of the first embodiment in the form of a flat plate, the concave portion (DT) of the first cutting surface (IC1) and the protrusion (PJ') of the second cutting surface (IC2) are maintained in a state of having a separation distance in the width direction (±x direction), and the protrusion (PJ) of the first cutting surface (IC1) and the concave portion (DT') of the second cutting surface (IC2) are maintained in a state of having a separation distance in the width direction (±x direction).

[0107] When a force that causes a cylindrical bending deformation is applied to the plate (10) of the first embodiment in the form of a flat plate, the distance between the concave portion (DT) of the first cutting surface (IC1) and the protrusion (PJ') of the second cutting surface (IC2) may be reduced, thereby forming an interlocking shape. In addition, the distance between the protrusion (PJ) of the first cutting surface (IC1) and the concave portion (DT') of the second cutting surface (IC2) may be reduced, thereby forming an interlocking shape.

[0108] In the first and second embodiments, a flat plate can be easily transformed into a cylindrical shape by forming a shape in which the concave portion (DT) of the first cutting surface (IC1) and the protrusion portion (PJ') of the second cutting surface (IC2) are interlocked with each other, and the protrusion portion (PJ) of the first cutting surface (IC1) and the concave portion (DT') of the second cutting surface (IC2) are interlocked with each other.

[0109] Figure 10a is an example 1-3 having a plurality of deformation parts (TP).

[0110] Embodiment 1-3 has a form in which, as an example, first and second cutting surfaces (IC1, IC2) are formed obliquely in one direction in the width direction (±x direction), and a plurality of deformation portions (TP) having a 'V'-shaped cross-section shape in the thickness direction (±z direction) are provided. In the drawing, two deformation portions (TP) of Embodiment 1-3 are provided in a form in which they cut the wall surface (WA) and cross the plate (10) of Embodiment 1 in the length direction (±y direction). The number of deformation portions (TP) is not limited thereto, and at least two or more may be provided.

[0111] The shape of the plurality of deformation portions (TP) is not limited thereto, and may include a shape having a 'U'-shaped cross-sectional shape in the thickness direction (±z direction), a shape having a 'V'-shaped cross-sectional shape including first and second cutting surfaces (IC1, IC2) that are not obliquely inclined and are opposed in the width direction (±x direction), and all of the shapes of the first embodiment and the first embodiment.

[0112] FIG. 10b is a first embodiment of the present invention having a shape including first and second cutting surfaces (IC1, IC2) that are opposite to each other in the width direction (±x direction) but having a flat bottom surface (BT) in the thickness direction (±z direction).

[0113] In the first to fourth embodiments, the first and second cutting surfaces (IC1, IC2) are formed vertically in the thickness direction (±z direction), and a plurality of deformation portions (TP) are formed as a flat surface with a bottom surface (BT) connecting the first and second cutting surfaces (IC1) and IC2. Accordingly, the first to fourth embodiments may have a concave shape composed of the first and second cutting surfaces (IC1, IC2) formed vertically with the flat bottom surface (BT).

[0114] Fig. 11 is a first embodiment 1-5 in which a wall surface (WA) forming an activated carbon charging chamber (11) is configured in the form of a plurality of columns (CL) and a deformation portion (TP) is provided through a gap space (SD) between two adjacent columns (CL). In the drawing, the columns (CL) are illustrated as square columns as an example. The shape of the columns (CL) forming the first embodiment 1-5 is not limited thereto and may include circular cylinders.

[0115] Embodiment 1-5 is formed through a gap space (SD) between two adjacent columns (CL), and as an example, the cross-sectional shape in the thickness direction (±z direction) may have a 'U' shape. The shape of Embodiment 1-5 is not limited thereto.

[0116] Fig. 12 is a 1-6 embodiment having a deformation portion (TP) on the inner side in the thickness direction (±z direction) and an outer deformation portion (OT) on the outer side in the thickness direction (±z direction).

[0117] Embodiment 1-6 includes, as an example, a deformation portion (TP) having a cross-sectional shape in the thickness direction (±z direction) in the shape of a 'V', and an outer deformation portion (OT) having a cross-sectional shape in the thickness direction (±z direction) in which the 'V' shape is flipped upside down in the thickness direction (±z direction). The shapes of the deformation portion (TP) and the outer deformation portion (OT) are not limited thereto.

[0118] The center line of the deformation part (TP) and the center line of the outer deformation part (OT) are positioned so as not to overlap but to be misaligned.

[0119] In the first embodiment, a thin-walled portion (TW) is provided on the lower side of a deformation portion (TP) provided on the inner side in the thickness direction (±z direction), and an inner thin-walled portion (IT) is provided on the upper side of an outer deformation portion (OT) provided on the outer side in the thickness direction (±z direction).

[0120] In the first embodiment, the thickness direction (±z direction) dimension of the deformation portion (TP) is larger than the thickness direction (±z direction) dimension of the thin portion (TW), and the thickness direction (±z direction) dimension of the outer deformation portion (OT) is larger than the thickness direction (±z direction) dimension of the inner thin portion (IT).

[0121] Fig. 13 is a 1-7th embodiment having a deformation portion (TP) in the form of a cut line.

[0122] In the first embodiment, a cutting line is formed with a dimension larger than the thickness direction (±z direction) dimension of a thin wall portion (TW) provided on the outer side in the thickness direction (±z direction) from the inner side in the thickness direction (±z direction). By the cutting line of the first embodiment, the wall surface (WA) is divided into two parts except for the thin wall portion (TW).

[0123] The plate (10) of the first embodiment of the present invention can be bent into a cylindrical shape by contacting one end and the other end so that the cutting line of the first to seventh embodiments is located on the inside in the thickness direction (±z direction).

[0124] The plate (10) of the first embodiment of the present invention is preferably formed in a form in which the wall surface (WA) divided into two is spread apart by the cutting line of the first to seventh embodiments, and the thin-walled portion (TW) is positioned on the inside in the thickness direction (±z direction) so that one end and the other end are in contact and can be bent and deformed into a cylindrical shape. The arrows in Fig. 13 indicate the direction in which the wall surface (WA) divided into two by the cutting line of the first to seventh embodiments is spread apart.

[0125] The plate (10) of the first embodiment of the present invention can be deformed into a cylindrical shape in which a deformation portion (TP) is provided in a linear shape like the cut line of the first to seventh embodiments, and a thin portion (TW) is positioned on the inside in the thickness direction (±z direction) and a deformation portion (TP) is positioned on the outside in the thickness direction (±z direction).

[0126] Figure 14a is an example of the 1st to 8th embodiment of the deformation portion (TP).

[0127] In the first embodiment of the present invention, the angle (θ) between the first horizontal line (HL1) located on the inner side in the thickness direction (±z direction) and the first cutting line (IL1) of the first cutting plane (IC1) is provided as an acute angle, and the angle (θ) between the second horizontal line (HL2) located on the outer side in the thickness direction (±z direction) and opposite to the first horizontal line (HL1) and the second cutting line (IL2) of the second cutting plane (IC2) is provided as an acute angle. The first embodiment of the present invention has a dimension smaller than the dimension of the wall surface (WA) in the thickness direction (±z direction) and is formed in a groove shape. Accordingly, the thin-walled portion (TW) is provided on the lower side in the thickness direction (±z direction) of the deformation portion (TP) of the first embodiment of the present invention.

[0128] In the first embodiment, the angle (θ) between the first cutting line (IL1) and the first horizontal line (HL1), and the angle (θ) between the second cutting line (IL2) and the second horizontal line (HL2) may preferably be provided in a range of 1° to 45°. More preferably, the angle (θ) between the first cutting line (IL1) and the first horizontal line (HL1), and the angle (θ) between the second cutting line (IL2) and the second horizontal line (HL2) may be provided in a range of 1° to 30°.

[0129] Accordingly, in the first embodiment, the width direction (±x direction) cross-sectional area of ​​the first cutting plane (IC1) can be formed relatively large, in a range of two to three times the width direction (±x direction) cross-sectional area of ​​the first cutting plane (IC1) in a form in which the angle (θ) between the first horizontal line (HL1) and the first cutting line (IL1) and the angle (θ) between the second horizontal line (HL2) and the second cutting line (IL2) are right angles (hereinafter, 'form having a right angle (θ)'). Likewise, the width direction (±x direction) cross-sectional area of ​​the second cutting plane (IC2) can be formed relatively large, in a range of two to three times the width direction (±x direction) cross-sectional area of ​​the second cutting plane (IC2) in a form in which the angle (θ) between the first horizontal line (HL1) and the first cutting line (IL1) and the angle (θ) between the second horizontal line (HL2) and the second cutting line (IL2) are perpendicular.

[0130] Embodiment 1-8 may be a preferable form for positioning the deformation portion (TP) toward the outside in the thickness direction (±z direction) and the thin portion (TW) toward the inside in the thickness direction (±z direction) when bending and deforming the plate (10) of Embodiment 1 in the form of a flat plate into a cylindrical shape.

[0131] The plate (10) of the first embodiment of the present invention has a shape of a deformation portion (TP) as in the first to eighth embodiments (a shape in which the angle (θ) between the first horizontal line (HL1) and the first cutting line (IL1), and the angle (θ) between the second horizontal line (HL2) and the second cutting line (IL2) are in a range of 1° to 30°). Accordingly, the plate (10) of the first embodiment can prevent the problem of the activated carbon (AC) of the activated carbon charging chamber (11) falling outward through the groove of the deformation portion (TP) in the process of deforming the flat plate shape into a cylindrical shape so that the deformation portion (TP) is positioned outward in the thickness direction (±z direction).

[0132] Specifically, in the process of deforming the plate (10) of the first embodiment in the form of a flat plate into a cylindrical shape so that the deformation portion (TP) is positioned outward in the thickness direction (±z direction), the first and second cutting surfaces (IC1, IC2) can be deformed by bending while spreading out in opposite directions with the y-axis as the central axis.

[0133] At this time, the plate (10) of the first embodiment of the present invention may be provided in a manner such that the cross-sectional area in the width direction (±x direction) of the first and second cut surfaces (IC1, IC2) through the first to eighth embodiments is at least two times and at most three times the cross-sectional area in the width direction (±x direction) of the first and second cut surfaces (IC1, IC2) in a form having a right angle (θ).

[0134] Accordingly, the plate (10) of the first embodiment of the present invention having the deformation portion (TP) of the first-eighth embodiment may have a portion where at least a portion of the first and second cutting surfaces (IC1, IC2) overlaps without a gap between the first and second cutting surfaces (IC1, IC2) during the process of being transformed from a flat plate shape into a cylindrical shape and in a state of being configured in a cylindrical shape. More specifically, an end portion located on the inner side in the thickness direction (±z direction) of the first cutting surface (IC1) and an end portion located on the outer side in the thickness direction (±z direction) of the second cutting surface (IC2) may overlap to form an overlapping portion.

[0135] In other words, in the process of being deformed into a cylindrical shape and in a state of being configured into a cylindrical shape, the plate (10) of the first embodiment may not have a gap in the wall surface (WA) of the activated carbon charging chamber (11) through the overlapping portions of the first and second cutting surfaces (IC1, IC2). As a result, the plate (10) of the first embodiment can prevent the problem of activated carbon (AC) falling out from the activated carbon charging chamber (11) having the deformed portion (TP).

[0136] Figure 14b is a diagram illustrating the first-ninth embodiment.

[0137] The first-ninth embodiment is configured such that the first cutting surface (IC1) includes a protrusion (PJ) and a concave portion (DT), and the second cutting surface (IC2) includes a protrusion (PJ') and a concave portion (DT').

[0138] In the first embodiment, the width direction (±x direction) dimension of the portion having the largest dimension in the width direction (±x direction) of each of the protrusion (PJ) of the first cutting surface (IC1) and the protrusion (PJ') of the second cutting surface (IC2) may be provided to be preferably 3 to 5 times the length direction (±y direction) dimension of each of the recessed portions (DT, DT'). Accordingly, the recessed depth in the width direction (±x direction) of the recessed portions (DT, DT') formed by the protrusions (PJ, PJ') can be formed relatively deep.

[0139] The plate (10) of the first embodiment of the present invention has the deformation portion (TP) of the first to ninth embodiments, and can prevent the problem of activated carbon (AC) falling out from the activated carbon charging chamber (11) during the process of being bent into a cylindrical shape so that the deformation portion (TP) is positioned on the outside in the thickness direction (±z direction). In addition, even when configured in a cylindrical shape, the problem of activated carbon (AC) falling out from the activated carbon charging chamber (11) can be prevented.

[0140] Specifically, when the plate (10) of the first embodiment in the form of a flat plate is bent and deformed into a cylindrical shape, the plate (10) of the first embodiment can be bent and deformed while the first and second cutting surfaces (IC1, IC2) are spread apart in opposite directions with the y-axis as the central axis. At this time, the largest width direction (±x direction) dimension of the protrusion (PJ, PJ') of each of the first and second cutting surfaces (IC1, IC2) is provided to be 3 to 5 times greater than the length direction (±y direction) dimension of the concave portion (DT, DT') of each of the first and second cutting surfaces (IC1, IC2), so that one end of the width direction (±x direction) of the protrusion (PJ) of the first cutting surface (IC1) and one end of the width direction (±x direction) of the protrusion (PJ') of the second cutting surface (IC2) overlap to form an overlapping portion.

[0141] The plate (10) of the first embodiment of the present invention having the first-ninth embodiment is deformed into a cylindrical shape by being bent by the overlapping portion, and in a state of being configured in a cylindrical shape, there is no gap in the activated carbon charging chamber (11) having the deformation portion (TP). As a result, the plate (10) of the first embodiment can prevent the problem of the activated carbon (10) falling outward from the activated carbon charging chamber (11) in a cylindrical shape having the deformation portion (TP) of the first-ninth embodiment, but positioning the deformation portion (TP) outward in the thickness direction (±z direction).

[0142] Meanwhile, the plate (10) of the first embodiment of the present invention may be configured in a cylindrical shape in which the deformation portion (TP) is positioned outward in the thickness direction (±z direction) by including other embodiments of the deformation portion (TP) described with reference to FIGS. 1 to 13.

[0143] Fig. 15 is a partially enlarged view of a second embodiment of the present invention. The plate (10') of the second embodiment may be configured to include a deformation portion (TP), a middle thin portion (MT), and an outer deformation portion (OT).

[0144] The plate (10') of the second embodiment may have a deformation portion (TP) that cuts across the activated carbon charging chamber (11) at the upper portion in the thickness direction (±z direction) based on the flat plate shape, and an outer deformation portion (OT) that cuts across the activated carbon charging chamber (11) at the lower portion in the thickness direction (±z direction).

[0145] The vertical center line in the thickness direction (±z direction) of the deformation portion (TP) and the vertical center line in the thickness direction (±z direction) of the outer deformation portion (OT) can be located on the same line. Accordingly, the outer deformation portion (OT) can be located below the thickness direction (±z direction) of the deformation portion (TP).

[0146] The deformation portion (TP) and the outer deformation portion (OT) may be provided with a distance apart in the thickness direction (±z direction). The plate (10') may be provided with an intermediate thin portion (MT) through the distance apart.

[0147] As an example, the deformation portion (TP) may be provided in a 'V' shape, and the outer deformation portion (OT) may be provided in a shape in which the angle (θ) between the first horizontal line (HL1) and the first cutting line (IL1), and the angle (θ) between the second horizontal line (HL2) and the second cutting line (IL2) preferably have a range of 1° or more and 30° or less. The shape of the outer deformation portion (OT) when the plate (10') is flipped up and down in the thickness direction (±z direction) may be the shape of the deformation portion (TP) of the first-eighth embodiment of FIG. 14a.

[0148] The plate (10') of the second embodiment is configured in a form in which the vertical center line in the thickness direction (±z direction) of the deformation portion (TP) and the vertical center line in the thickness direction (±z direction) of the outer deformation portion (OT) are positioned on the same line, so that it is easy to bend from a flat plate shape to a cylindrical shape, and the problem of activated carbon (AC) falling off from the activated carbon charging chamber (11) during the bending deformation process and in the state configured in the cylindrical shape can be prevented.

[0149] Specifically, the plate (10') of the second embodiment may preferably be provided in a cylindrical shape with the deformation portion (TP) positioned on the inner side (upper side in the flat plate shape) in the thickness direction (±z direction) and the outer deformation portion (OT) positioned on the outer side (lower side in the flat plate shape).

[0150] The plate (10') of the second embodiment can be easily bent through the deformation portion (TP) during the process of being bent from a flat shape to a cylindrical shape. When the plate (10') is bent into a cylindrical shape, the upper portion of the deformation portion (TP) in the thickness direction (±z direction) can be folded. Accordingly, the cylindrical plate (10') can prevent the problem of activated carbon (AC) falling off from the inside of the activated carbon charging chamber (11) in the thickness direction (±z direction).

[0151] In addition, the plate (10') has an outer deformation portion (OT) having a shape in which the angle (θ) between the first cutting line (IL1) and the angle (θ) between the second horizontal line (HL2) and the second cutting line (IL2) on the outer side in the thickness direction (±z direction) is in a range of 1° to 30°, so that no gap exists on the outer side in the thickness direction (±z direction) when configured in a cylindrical shape. This can prevent the problem of activated carbon (AC) falling out from the activated carbon charging chamber (11).

[0152] The plate (10') of the second embodiment has a deformation portion (TP) and an outer deformation portion (OT) in which the vertical center line in the thickness direction (±z direction) of the deformation portion (TP) and the vertical center line are positioned on the same line, thereby preventing the problem of activated carbon (AC) falling out from the activated carbon charging chamber (11) in the process of being bent and deformed from a flat plate shape into a cylindrical shape and in a state configured in a cylindrical shape.

[0153] Due to this, the plate (10') can prevent the deodorizing function from being reduced due to the activated carbon (AC) being charged insufficiently in the activated carbon charging chamber (11) compared to the standard amount.

[0154] The deformation portion (TP) may be configured in various embodiments described with reference to FIGS. 1 to 14b, and the outer deformation portion (OT) may also be provided in the shape of various embodiments of the deformation portion (TP) described with reference to FIGS. 1 to 14b.

[0155] Referring to FIG. 15, as an example, the plate (10') of the second embodiment is described as being configured as a cylinder with the deformation portion (TP) positioned on the inside in the thickness direction (±z direction) and the outer deformation portion (OT) positioned on the outside. However, the plate (10') of the second embodiment may also be configured as a cylinder with the deformation portion (TP) positioned on the outside in the thickness direction (±z direction) and the outer deformation portion (OT) positioned on the inside.

[0156] FIG. 16 is an enlarged perspective view of a portion of a plate (10") of a third embodiment of the present invention, FIG. 17 is a plan view of a plate (10") of a third embodiment, and FIG. 18 is an enlarged view of a portion of a plate (10") of a third embodiment.

[0157] Referring to FIGS. 16 to 18, the plate (10") of the third embodiment may be configured to include a groove-shaped deformation portion (TP) that crosses the portion where the corner portions (EG) of each space (SP) formed by the activated carbon charging chamber (11) meet.

[0158] The plate (10") of the third embodiment is preferably provided with a plurality of activated carbon charging chambers (11) in a square structure.

[0159] A square structure is a structure in which four vertices forming a square cross-section shape are shared as one of the vertices forming another square cross-section shape and are connected as one.

[0160] Accordingly, each activated carbon charging chamber (11) may be provided as a square column-shaped empty space having a square cross-sectional shape. The activated carbon charging chamber (11) is provided in such a way that two of the four vertices of the square cross-sectional shape, which are opposite to each other, are located on one side and the other side in the length direction (±y direction), and the remaining two opposite vertices are located on one side and the other side in the width direction (±x direction).

[0161] Each activated carbon charging chamber (112) provided on the plate (10") of the third embodiment may be provided as a square column-shaped empty space having a square cross-sectional shape. Each activated carbon charging chamber (11) may have a space (SP) formed by four wall surfaces (WA). Accordingly, one space (SP) may be provided as a tetrahedron having a square cross-sectional shape. The four wall surfaces (WA) may be shared to function as the wall surfaces (WA) of another adjacent activated carbon charging chamber (11) to form another adjacent independent space (SP).

[0162] Accordingly, the plate (10") of the third embodiment can be formed into a square structure in which a plurality of activated carbon charging chambers (11) share a wall surface (WA) with each other and share four vertices forming a square cross-section shape and are integrally connected.

[0163] The plate (10") of the third embodiment is a form in which activated carbon charging chambers (11) having a rectangular cross-sectional shape are arranged in a plurality of rows in the longitudinal direction (±y direction) and a plurality of columns in the width direction (±x direction). At this time, the activated carbon charging chamber (11) is a form in which, among the four vertices of the rectangular cross-sectional shape, two vertices are positioned opposite each other on one side and the other side in the length direction (±y direction), and the remaining two vertices are positioned opposite each other on one side and the other side in the width direction (±x direction).

[0164] Accordingly, in each activated carbon charging chamber (11), a plurality (four) of wall surfaces (WA) forming an independent space (SP) include first and third wall surfaces (WA1, WA3) and second and fourth wall surfaces (WA2, WA4) that are diagonally opposed on the xy plane.

[0165] Each space (SP) forming an activated carbon charging chamber (11) has an edge portion (EG) formed by adjacent wall surfaces (WA). More specifically, one space (SP) has an edge portion (EG) formed by a portion where adjacent first and second wall surfaces (WA1, WA2) meet, and an edge portion (EG) formed by a portion where adjacent third and fourth wall surfaces (WA1, WA2) meet. In addition, one space (SP) has an edge portion (EG) formed by a portion where adjacent first and third wall surfaces (WA1, WA3) meet, and an edge portion (EG) formed by a portion where adjacent second and fourth wall surfaces (WA2, WA4) meet. Accordingly, one space (SP) has four edge portions (EG) formed by portions where adjacent wall surfaces (WA) meet. The four edge portions (EG) correspond to the positions of four vertices of a rectangular cross-section shape. Accordingly, two of the four corners (EG) are positioned so as to face each other on one side and the other side in the length direction (±y direction) in the space (SP), and the remaining two corners (EG) are positioned so as to face each other on one side and the other side in the width direction (±x direction).

[0166] The activated carbon charging chamber (11) provided by the space (SP) is arranged in a plurality of rows and a plurality of columns. At this time, one space (SP) is provided in a form in which it meets another adjacent space (SP) at a corner (EG) in at least one of the longitudinal direction (±y direction) and the width direction (±x direction).

[0167] The plate (10") of the third embodiment has a groove-shaped deformation portion (TP) that crosses the area where the corner portions (EG) of each space (SP) meet.

[0168] As an example, the first and second spaces (SP1, SP2) may be provided adjacent to each other in the longitudinal direction (±y direction).

[0169] The first and second spaces (SP1, SP2) have four corners (EG) formed by the points where the first and second walls (WA1, WA2), the first and third walls (WA1, WA3), the second and fourth walls (WA2, WA4), and the third and fourth walls (WA3, WA4) meet each other.

[0170] The first and second spaces (SP1, SP2) each meet at one of the corners (EG) located in the longitudinal direction (±y direction). For example, since the first space (SP1) and the second space (SP2) are arranged adjacent to each other in the longitudinal direction (±y direction), the corner (EG) located on one side of the longitudinal direction (±y direction) of the first space (SP1) and the corner (EG) located on one side of the longitudinal direction (±y direction) of the second space (SP2) correspond and meet.

[0171] The plate (10") of the third embodiment has a deformation portion (TP) that crosses the portion where the corner portions (EG) of the first and second spaces (SP1, SP2) meet. The deformation portion (TP) is preferably provided in the form of a groove having a V-shaped cross-sectional shape in the thickness direction (±z direction).

[0172] The deformation portion (TP) includes a first inclined portion (SL1) formed on the upper side in the thickness direction (±z direction) of two wall surfaces (WA) forming an edge portion (EG) of a first space (SP1) and a second inclined portion (SL2) formed on the upper side in the thickness direction (±z direction) of two wall surfaces (WA) forming an edge portion (EG) of a second space (SP2).

[0173] Specifically, the first space (SP1) has a first inclined portion (SL1) above the thickness direction (±z direction) of the corner portion (EG) formed by the first and second walls (WA1, WA2), the first and third walls (WA1, WA3), the second and fourth walls (WA2, WA4), and the third and fourth walls (WA3, WA4).

[0174] The first inclined portion (SL1) is formed by cutting the upper portion of the corner portion (EG) in the thickness direction (±z direction) diagonally, while forming the corner portion (EG) through two adjacent wall surfaces (WA). The upper portion of the corner portion (EG) separated by cutting has a triangular cross-sectional shape. The portion of the corner portion (EG) formed through two adjacent wall surfaces (WA) where cutting is performed is cut to have a V-shaped cross-sectional shape in the width direction (±x direction) or the thickness direction (±z direction).

[0175] The first slope portion (SL1) is formed by cutting the upper portion of the corner portion (EG) formed by two adjacent wall surfaces (WA) in the thickness direction (±z direction) in a diagonal direction that can form a cut having a triangular cross-sectional shape.

[0176] As an example, the first slope (SL1) can be provided in a form in which the upper portion of the corner (EG) formed by the adjacent third and fourth walls (WA3, WA4) of the first space (SP1) is cut diagonally in the thickness direction (±z direction).

[0177] The second space (SP2) has a second inclined portion (SL2) above the thickness direction (±z direction) of the corner portion (EG) formed by the first and second walls (WA1, WA2), the first and third walls (WA1, WA3), the second and fourth walls (WA2, WA4), and the third and fourth walls (WA3, WA4).

[0178] The second slope portion (SL2) is provided in the same form as the first slope portion (SL1). Specifically, it is provided in a form in which the upper portion of the thickness direction (±z direction) of the edge portion (EG) is cut diagonally while forming the edge portion (EG) through two adjacent wall surfaces (WA). The upper portion of the cut edge portion (EG) has a triangular cross-sectional shape.

[0179] As an example, the second slope (SL2) can be provided in a form in which the upper portion of the corner (EG) formed by the adjacent first and second walls (WA1, WA2) of the second space (SP2) is cut diagonally in the thickness direction (±z direction).

[0180] Through this, the plate (10") of the third embodiment has a deformation portion (TP) formed by first and second inclined portions (SL1, SL2) that are opposed to each other in the longitudinal direction (±y direction) at the point where the corner portions (EG) of the first and second spaces (SP1, SP2) meet. As an example, the first and second inclined portions (SL1, SL2) are formed in a shape in which the upper portions of the corner portions (EG) are cut in a diagonal direction in a straight line and are opposed to each other.

[0181] The deformation portion (TP) has a groove shape having a V-shaped cross-sectional shape when viewed in at least one of the longitudinal direction (±y direction) and the width direction (±x direction) as it is formed by the first and second inclined portions (SL1, SL2).

[0182] The plate (10") of the third embodiment can be deformed into a round shape as the first and second slopes (SL1, SL2) come closer to each other. Through this, the plate (10") of the third embodiment can be configured as a filter, preferably a cylindrical filter.

[0183] The plate (10") of the third embodiment can be deformed into a round shape while being bent in the direction of bringing the first and second inclined portions (SL1, SL2) into contact. More specifically, the first inclined portion (SL1) of the first space (SP1) includes a first-first inclined portion (SL1-1) provided on one of two adjacent wall surfaces (WA) and a first-second inclined portion (SL1-2) provided on the other of the two adjacent wall surfaces (WA) adjacent to and opposite the first-first inclined portion (SL1-1). The second inclined portion (SL2) of the second space (SP2) includes a second-first inclined portion (SL2-1) provided on one of two adjacent wall surfaces (WA) and a second-second inclined portion (SL2-2) provided on the other of the two adjacent wall surfaces (WA) adjacent to and opposite the second-first inclined portion (SL2-1).

[0184] The plate (10") of the third embodiment is deformed into a round shape through the deformation portion (TP) while bringing the first and second inclined portions (SL1, SL2) into contact. Accordingly, the plate (10") of the third embodiment is deformed into a round shape and, in a state configured as a filter, brings into contact the first-first inclined portion (SL1-1) of the third wall surface (WA3) of the first space (SP1) and the second-first inclined portion (SL2-1) of the first wall surface (WA1) of the second space (SP2), and brings into contact the first-second inclined portion (SL1-2) of the fourth wall surface (WA4) of the first space (SP1) and the second-second inclined portion (SL2-2) of the second wall surface (WA2) of the second space (SP2).

[0185] In this way, the plate (10") of the third embodiment can more easily implement a transformation into a cylindrical shape in a round shape by forming a deformation portion (TP) that crosses the area where the corner portions (EG) of two adjacent spaces (SP) including the first and second inclined portions (SL1, SL2) meet through the first inclined portion of the first space (SP1) and the second inclined portion (SL2) of the second space (SP2).

[0186] In addition, the plate (10") of the third embodiment can be easily deformed into a cylindrical shape through a deformation portion (TP) crossing the corner portion (EG) without providing a space between the spaces (SP) forming the activated carbon charging chamber (11). Accordingly, the plate (10") of the third embodiment can utilize the entire area as an area containing activated carbon, thereby maximizing the deodorizing performance.

[0187] A thin wall portion (TW) is provided at the lower portion of the deformation portion (TP). The thin wall portion (TW) is provided through a portion of the corner portion (EG) where the deformation portion (TP) is not formed. Accordingly, the thin wall portion (TW) is provided at the lower portion of the deformation portion (TP) at a position corresponding to the deformation portion (TP) in the thickness direction (±z direction). The thin wall portion (TW) may be a portion that integrally connects each space (SP).

[0188] Meanwhile, the first and second inclined portions (SL1, SL2) of the deformation portion (TP) may be formed in corresponding shapes. For example, one of the first and second inclined portions (SL1, SL2) may be formed concavely, and the other may be formed convexly. Accordingly, when the plate (10") of the third embodiment is deformed into a round shape, the first and second inclined portions (SL1, SL2) that are in contact may be complementarily coupled.

[0189] Referring to FIG. 17, the plate (10") of the third embodiment may have a deformation portion (TP) only in at least a portion, and may have a corner portion (EG) formed by a portion where two adjacent wall surfaces (WA) meet without having a deformation portion (TP) in the remaining portion.

[0190] The plate (10") of the third embodiment may preferably have a deformation portion (TP) only at the corner portion (EG) of a space (SP) arranged in an even or odd column among the spaces (SP) arranged in a plurality of columns.

[0191] As an example, a deformation portion (TP) may be provided at a corner (EG) of a space (SP) arranged in an even column, and a deformation portion (TP) may not be provided at a corner (EG) of a space (SP) arranged in an odd column. Conversely, a deformation portion (TP) may be provided at a corner (EG) of a space (SP) arranged in an odd column, and a deformation portion (TP) may not be provided at a corner (EG) of a space (SP) arranged in an even column.

[0192] In the drawing, odd-numbered columns include the 1st column (R1), the 3rd column (R3), the 5th column (R5), the 7th column (R7), the 9th column (R9), the 11th column (R11), the 13th column (R13), and the 15th column (R15). Even-numbered columns include the 2nd column (R2), the 4th column (R4), the 6th column (R6), the 8th column (R8), the 10th column (R10), the 12th column (R12), and the 14th column (R14).

[0193] The plate (10") of the third embodiment may have a shape in which only the corners (EG) of at least some of the spaces (SP) (for example, the spaces (SP) arranged in even or odd rows) among the plurality of spaces (SP) have deformation parts (TP), and the corners (EG) of the remaining spaces (SP) do not have deformation parts (TP).

[0194] In this case, the plate (10") of the third embodiment can be easily deformed into a round shape through a portion having a deformation portion (TP) (for example, a deformation portion (TP) formed at a corner portion (EG) of a space (SP) arranged in an even or odd row).

[0195] Fig. 19 is an enlarged perspective view of a portion of the plate of the fourth embodiment.

[0196] Referring to Fig. 19, the plate of the fourth embodiment has a deformation portion (TP) that crosses the portion where the corner portions (EG) of the first and second spaces (SP1, SP2) meet in either the longitudinal direction (±z direction) or the width direction (±x direction).

[0197] As an example, the deformation portion (TP) may preferably be provided as a deformation portion (TP) that crosses the portion where the corner portions (EG) of the first and second spaces (SP1, SP2) meet in the longitudinal direction (±z direction). In this case, the deformation portion (TP) is provided in the form of a groove having a V-shaped cross-sectional shape in the longitudinal direction (±z direction).

[0198] The deformation portion (TP) includes a first inclined portion (SL1') formed as an inclined surface, and a second inclined portion (SL2') formed as an inclined surface and adjacent to and facing the first inclined portion (SL1') in the width direction (±x direction).

[0199] The first and second slope portions (SL1', SL2') are formed by cutting an edge portion (EG) formed by two adjacent walls (WA) in the longitudinal direction (±y direction) to have a V-shaped cross-section in the width direction (±x direction), and providing a slope corresponding to the cut portion and slanting diagonally to the cut portion. Therefore, the first slope portion (SL1') is composed of a slope.

[0200] More specifically, a V-shaped cut portion in the longitudinal direction (±y direction) intersects the portion where the corners (EG) of the first and second spaces (SP1, SP2) that are adjacent to each other in the longitudinal direction (±y direction). As a result, the corners (EG) formed where the first and third wall surfaces (WA1, WA3) that are adjacent in the longitudinal direction (±y direction) meet are cut to have a V-shaped cross-sectional shape in the width direction (±x direction), thereby forming a cut portion. An inclined surface that fills the cut portion formed between the first and third wall surfaces (WA1, WA3) is provided, and a first inclined portion (SL1') is provided by the inclined surface.

[0201] In addition, a V-shaped cut portion in the longitudinal direction (±y direction) intersects the portion where the corners (EG) of the first and second spaces (SP1, SP2) that are adjacent to each other in the longitudinal direction (±y direction). As a result, the corners (EG) formed by the second and fourth wall surfaces (WA2, WA4) that are adjacent in the longitudinal direction (±y direction) are cut to have a V-shaped cross-sectional shape in the width direction (±x direction), and a cut portion is formed. An inclined surface that fills the cut portion formed between the second and fourth wall surfaces (WA2, WA4) is provided, and a second inclined portion (SL2') is provided by the inclined surface.

[0202] In other words, the first and second inclined portions (SL1', SL2') are formed by a V-shaped cut portion at a point where the first and third walls (WA1, WA3) and the second and fourth walls (WA2, WA4) meet, by a V-shaped cut portion that crosses the longitudinal direction (±y direction) at the point where the corners (EG) of the first and second spaces (SP1, SP2) meet, and then the cut portion is filled and blocked by an inclined surface.

[0203] The plate of the fourth embodiment has a deformation portion (TP) including a cut portion that crosses the portion where the corner portions (EG) of the first and second spaces (SP1 and SP2) meet in the longitudinal direction (±y direction), and first and second inclined portions (SL1', SL2') that are formed as inclined surfaces that fill the cut portions formed at the portions where two adjacent wall surfaces ((WA1, WA3), (WA2, WA4)) meet in the longitudinal direction (±y direction) by the cut portions that cross the longitudinal direction (±y direction). Accordingly, the plate of the fourth embodiment has a V-shaped cross-sectional groove that crosses the corner portion (EG) formed where two adjacent wall surfaces (WA) meet in the longitudinal direction (±y direction). Meanwhile, in the width direction (±x direction), a first inclined portion (SL1') or a second inclined portion (SL') formed as a diagonally inclined surface is provided at a corner portion (EG) formed by two adjacent wall surfaces (WA) meeting.

[0204] Meanwhile, the plate of the fourth embodiment may include a deformation portion (TP) formed by first and second inclined portions (SL1', SL2') formed as a groove and an inclined surface that cross the portion where the corners (EG) of the first and second spaces (SP1, SP2) meet in the width direction (±x direction). In this case, the first inclined portion (SL1') or the second inclined portion (SL') formed as an inclined surface that is inclined in a diagonal direction may be provided at a cut portion that cuts the corner portion (EG) formed where two adjacent wall surfaces (WA) meet in the length direction (±y direction). Meanwhile, in the width direction (±x direction), the plate may be provided with a V-shaped groove that crosses the corner portion (EG) formed where two adjacent wall surfaces (WA) meet.

[0205] The plate of the fourth embodiment has a deformation portion (TP) that crosses the portion where the corner portions (EG) of the first and second spaces (SP1, SP2) meet in the longitudinal direction (±y direction), so that when round deformation is performed with the axis in the thickness direction (±y direction) as the round deformation axis, the inclined surfaces forming the first and second inclined portions (SL1', SL2') come into contact with each other and can be easily rounded.

[0206] The first inclined portion (SL1') and the second inclined portion (SL') are connected to each other at the lower side of the wall surface (WA), and may be formed to become further apart from each other as they go upwards of the wall surface (WA). The first inclined portion (SL1') and the second inclined portion (SL') may contact each other when the plate is roundly deformed, and may have complementary shapes. For example, the first inclined portion (SL1') may be formed convexly, and complementarily, the second inclined portion (SL') may be formed concavely.

[0207] The plates of the first to fourth embodiments of the present invention described above have a first mesh net (12) bonded to one surface to close one opening in the thickness direction (±z direction) of a plurality of activated carbon charging chambers (11), and each of the plurality of activated carbon charging chambers (11) is filled with activated carbon (AC), and then the activated carbon (AC) is charged, thereby functioning as an activated carbon (AC) inlet, and the other open opening can be closed by a second mesh net (13). The first mesh net (12) and the second mesh net (13) can be heat-sealed to one surface and the other surface of the plate or bonded by an adhesive.

[0208] As described above, the present invention has been described with reference to preferred embodiments thereof, but it will be understood by those skilled in the art that various modifications or variations may be made to the present invention without departing from the spirit and scope of the present invention as set forth in the following claims.
