Description

Technical Field

[0001] The present invention relates to a filter laminate for adsorbing odor components and performing deodorization.

Background Art

[0002] Conventionally, it has been known that charcoal (especially activated carbon) has a high deodorizing effect. Charcoal is a porous material having many pores, and its surface area is said to be 200 m 2 ~400 m 2 per 1 g. Thus, charcoal adsorbs odorous substances by strong intermolecular forces and exhibits a deodorizing effect. For this reason, various filters utilizing the deodorizing effect of charcoal have been proposed.

[0003] For example, Patent Document 1 discloses a filter formed by alternately laminating three honeycomb craft papers and two nets, and storing activated carbon in the middle honeycomb craft paper.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Since such a filter is a consumable, an economical configuration that is easy to manufacture without waste of materials is required. Further, since charcoal can be reused, it is desirable that it can be easily separated and recovered from other members. However, the above-described techniques are insufficient in these respects.

[0006] The present invention has been made in view of such conventional circumstances. One object of the present invention is to provide a filter that reduces material loss, is easy to manufacture, and allows easy separation and recovery of charcoal. Means for Solving the Problems and Effects of the Invention

[0007] The filter according to the first aspect of the present invention comprises a honeycomb structure having a first surface formed by one bottom surface of each hollow column and a second surface formed by the other bottom surface of each hollow column, wherein a deodorizing member made of granular charcoal or granular activated charcoal is placed inside the plurality of hollow columns, and a first sheet-like member is a sheet-like member made of a breathable material and is adhered to the first surface, and a breathable material The packaging can be configured to include: a second sheet-like member which is made of a material and is adhered to the second surface but not adhered to the first sheet-like member; a third surface which encloses the honeycomb structure, the deodorizing member, the first sheet-like member and the second sheet-like member, is a surface facing the first surface and has a third opening; a fourth surface which is a surface facing the second surface and has a fourth opening; and an opening which opens the third surface so that the first sheet-like member can be peeled off from the first surface and the deodorizing member can be taken out from the plurality of hollow columnar bodies.

[0008] A filter according to a second aspect of the present invention can be configured such that the opening is a perforation that is arranged along all or part of the edge forming the third surface.

[0009] A filter according to a third aspect of the present invention can be configured such that the third surface is rectangular, and the opening is a perforation arranged along three of the four sides forming the third surface.

[0010] According to the above configuration, since only a plurality of hollow columns are arranged, that is, the hollow columns are not cut in a way that would prevent them from maintaining their hollow column shape, material loss can be reduced. Furthermore, the resulting irregularities in the outer shape of the honeycomb structure 11 can be covered by the frame 15. In addition, since the first sheet-like member and the second sheet-like member are not bonded to each other, their size can be reduced compared to when they are bonded to each other, further reducing material loss. Moreover, in the manufacture of the filter, processes such as bonding the first sheet-like member and the second sheet-like member and cutting off excess parts are unnecessary, making manufacturing easier. Furthermore, by peeling the first sheet-like member from the first surface, the deodorizing member can be easily separated and recovered from within the honeycomb structure. In addition, since the frame has an opening that opens to the third surface, the first sheet-like member can be easily peeled from within the honeycomb structure, and consequently, the deodorizing member can be more easily separated and recovered from within the honeycomb structure. Thus, the filter according to the present invention achieves the aforementioned excellent effects through the close relationship and integration of a honeycomb structure, a first sheet-like member, a second sheet-like member, and a frame, each having specific characteristics.

[Modes for carrying out the invention]

[0012] Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments shown below are illustrative examples for realizing the technical concept of the present invention, and the present invention is not limited to these. Furthermore, this specification does not limit the members shown in the claims to the members of the embodiments. In particular, the dimensions, materials, shapes, relative arrangements, etc. of the components described in the embodiments are not intended to limit the scope of the present invention to those, unless otherwise specifically stated, but are merely illustrative examples. Note that the size and positional relationships of the members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same name and reference numerals indicate the same or similar members, and detailed explanations are omitted as appropriate. Furthermore, each element constituting the present invention may be configured such that multiple elements are made of the same material, with one material serving multiple elements, or conversely, the function of one material may be shared among multiple materials. Furthermore, the function or processing of each element constituting the present invention may be realized by artificial intelligence (AI) to the extent possible. [Filter 1]

[0013] A filter 1 according to one embodiment of the present invention will be described with reference to Figures 1 to 5.

[0014] As shown in Figures 1 to 4, filter 1 mainly consists of a honeycomb structure 11, a deodorizing member 12, a first sheet-like member 13, a second sheet-like member 14, and a frame 15. Each member will be described below. [Honeycomb structure 11]

[0015] As shown in Figure 5, the honeycomb structure 11 is a member having a honeycomb structure formed by connecting hollow cylindrical bodies 111 (corresponding to an example of a "hollow cylindrical body" in the claims) so that their side surfaces are in contact with each other. Here, "honeycomb" is not limited to the narrow sense of "a series of regular hexagonal prisms arranged without gaps," but rather has a broader meaning of "a series of three-dimensional shapes, not limited to regular hexagonal prisms, arranged without gaps."

[0016] Further, each hollow cylinder 111 is arranged such that the positions of both bottom surfaces are substantially aligned with the positions of both bottom surfaces of adjacent hollow cylinders. As shown in FIG. 3, the honeycomb structure 11 has a first surface 112 formed by one bottom surface of each hollow cylinder 111 and a second surface 113 formed by the other bottom surface.

[0017] Also, in the honeycomb structure 11, with the deodorizing member 12 disposed inside the hollow cylinder 111, the first sheet-like member 13 is adhered to the first surface 112 and the second sheet-like member 14 is adhered to the second surface 113, thereby restricting the movement of the deodorizing member 12 out of the hollow cylinder 111. Thereby, it is possible to prevent the deodorizing member 12 from being biased within the filter 1, and thus to prevent the bias of air permeability and deodorizing effect.

[0018] Also, as shown in FIG. 5, the honeycomb structure 11 is formed in a shape that fits within a substantially rectangular frame 15 without being cut in such a way that the hollow cylinder 111 cannot maintain its hollow cylinder shape. The "cut that cannot maintain the hollow cylinder shape" mentioned here is, for example, the cut shown in FIG. 6. In this figure, the hollow cylinder is cut such that the end face is C-shaped and cannot maintain its hollow cylinder shape (the same can be said for hollow cylinder shapes other than the hollow cylinder). And the description "only a plurality of hollow cylinders" in the claims means that the cut that cannot maintain the hollow cylinder shape does not include the hollow cylinder.

[0019] Note that the honeycomb structure 11 is not limited to the above-described embodiment. For example, a honeycomb structure may be formed by connecting hollow triangular cylinders such that their side surfaces are in contact with each other, or a honeycomb structure may be formed by connecting hollow hexagonal cylinders such that their side surfaces are in contact with each other.

[0020] Also, the outer shape of the honeycomb structure 11 only needs to be a shape that can fit within the frame 15 and is not particularly limited. When actually designing and manufacturing the filter 1, first, the space where the filter 1 is to be applied is determined, and accordingly, the shape of the frame 15 is determined. Then, the outer shape of the honeycomb structure 11 may be determined according to the frame 15. 〔Deodorizing member 12〕

[0021] As shown in FIGS. 1 to 4, the deodorizing member 12 is granular charcoal (preferably activated carbon). Charcoal is a porous material having many pores and is characterized by a large surface area. The deodorizing member 12 according to the present invention further increases the surface area by making such charcoal granular. Thereby, the deodorizing member 12 can adsorb odor substances by strong intermolecular forces and deodorize efficiently.

[0022] Note that the deodorizing member 12 is not limited to the above-described aspect, and it may be a mixture of materials having a deodorizing effect other than charcoal. Also, the particle size of the charcoal is not particularly limited, but smaller particle size is preferable because the overall surface area becomes larger, the deodorizing effect is enhanced, and the air permeability of the filter 1 is enhanced (pressure loss is reduced). Furthermore, the amount of the deodorizing member 12 used in the filter 1 is not particularly limited. Increasing the amount of the deodorizing member 12 increases the duration during which the deodorizing effect of the filter 1 lasts, and decreasing the amount of the deodorizing member 12 increases the air permeability of the filter 1. Therefore, it may be appropriately adjusted according to the application. 〔First sheet-like member 13 and second sheet-like member 14〕

[0023] As shown in FIGS. 1 to 4, the first sheet-like member 13 and the second sheet-like member 14 are mesh sheets having air permeability. The first sheet-like member 13 is adhered to the first surface 112, and the second sheet-like member 14 is adhered to the second surface 113. On the other hand, the first sheet-like member 13 and the second sheet-like member 14 are not adhered to each other, and the first sheet-like member 13 and the second sheet-like member 14 sandwich the honeycomb structure 11.

[0024] As a result, the first sheet-like member 13 and the second sheet-like member 14 block the holes in each hollow cylindrical body 111, restricting the movement of the deodorizing member 12 from inside the hollow cylindrical body 111, preventing the deodorizing member 12 from becoming unevenly distributed within the filter 1, and consequently preventing unevenness in airflow and deodorizing effect.

[0025] Furthermore, the first sheet-like member 13 can be easily peeled off from the honeycomb structure 11, and consequently, the deodorizing member 12 can be easily separated and recovered from within the honeycomb structure 11.

[0026] Furthermore, in the manufacturing of filter 1, processes such as bonding the first sheet-like member 13 and the second sheet-like member 14 and cutting off excess portions are unnecessary, and less mesh sheet is needed for the first sheet-like member 13 and the second sheet-like member 14, making filter 1 economical.

[0027] The first sheet-like member 13 and the second sheet-like member 14 are not limited to the embodiments described above. Any embodiment that can close the holes in each hollow cylindrical body 111 is acceptable, and they can be appropriately modified to match the outer shape of the honeycomb structure 11. [Frame 15]

[0028] As shown in Figures 1 to 4, the frame 15 is a substantially rectangular member that encloses the honeycomb structure 11, the first sheet-like member 13, and the second sheet-like member 14. It has a third opening 152 on the third surface 151 facing the first surface 112, and a fourth opening 154 on the fourth surface 153 facing the second surface 113. Furthermore, as shown in Figure 2, the frame 15 has perforations 155 (corresponding to an example of an "opening" in the claims) arranged along three of the four sides forming the third surface 151.

[0029] As shown in Figure 5, the honeycomb structure 11 is formed without cutting the hollow cylindrical body 111 in a way that would prevent it from maintaining its hollow cylindrical shape, resulting in an uneven outer shape. However, by providing the frame 15, the unevenness of the honeycomb structure 11 can be covered, making the outer shape of the filter 1 approximately rectangular.

[0030] Furthermore, by having a third opening 152 and a fourth opening 154, the frame 15 does not obstruct the airflow of the honeycomb structure 11, the first sheet-like member 13, and the second sheet-like member 14.

[0031] Furthermore, by cutting the frame 15 along the perforations 155, the third surface 151 can be opened wide, as shown in Figure 4. This allows the first sheet-like member 13 to be easily peeled off from the honeycomb structure 11, and consequently, the deodorizing member 12 to be more easily separated and recovered from within the honeycomb structure 11.

[0032] Note that the frame 15 is not limited to the embodiments described above. For example, the shape of the frame 15 can be appropriately changed to suit the space to which the filter 1 is applied, and the characteristics of the perforations 155 (shape, position, size, etc.) can also be appropriately changed.

[0033] For example, if the frame 15 is circular in shape, only one edge will form the third surface 151. In this case, a portion of the edge can be left intact, and perforations 155 can be provided along that edge.

[0034] Furthermore, the perforations 155 are not limited to being arranged along a portion of the edge forming the third surface 151, but may be arranged along all of the edge forming the third surface 151. In this case, the third surface 151 can be completely separated by cutting the frame 15 along the perforations 155.

[0035] Furthermore, the perforations 155 are not limited to a shape along the edge forming the third surface 151. For example, some perforations may be semicircular in shape to facilitate the formation of holes for gripping fingers when cutting the frame 15 along the perforations 155.

[0036] Furthermore, the term "opening" in the claims is not limited to perforations. For example, if slits are provided on three of the four sides forming the third surface 151, and the honeycomb structure 11, the first sheet-like member 13, and the second sheet-like member 14 are enclosed within, the slits may be sealed with adhesive tape. When separating and recovering the deodorizing member 12 from the honeycomb structure 11, the adhesive tape may be peeled off to open the third surface 151 wide. [Effect of Filter 1]

[0037] A filter 1 according to one embodiment of the present invention solves the problem of "providing a filter that reduces material loss, is easy to manufacture, and facilitates the separation and recovery of charcoal" through the configuration of its constituent components: honeycomb structure 11, first sheet-like member 13, second sheet-like member 14, and frame 15.

[0038] Specifically, firstly, the filter 1 reduces material loss because it is not cut in a way that would prevent the hollow cylindrical body 111 from maintaining its hollow cylindrical shape. Also, although this results in irregularities on the outer surface of the honeycomb structure 11, the frame 15 covers these irregularities. Previously, the honeycomb structure (finished product) was cut from a large honeycomb structure (material) to fit the space where the filter 1 was to be applied, resulting in scraps.

[0039] Next, because the first sheet-like member 13 and the second sheet-like member 14 are not bonded to each other, their size can be reduced compared to when they are bonded, thereby reducing material waste. Also, in the manufacturing of the filter 1, the process of bonding the first sheet-like member 13 and the second sheet-like member 14 and cutting off the excess is unnecessary, making manufacturing easier. Furthermore, by peeling the first sheet-like member 13 from the first surface 112, the deodorizing member 12 can be easily separated and recovered from the honeycomb structure 11. Conventionally, when a hollow column was cut in a way that prevented it from maintaining its hollow column shape, the first sheet-like member and the second sheet-like member were bonded together to form a bag, which prevented the movement of the deodorizing member placed inside the cut hollow column. In such cases, the required material increases, and the manufacturing process is lengthy. In addition, unless the first sheet-like member was also peeled from the second sheet-like member, it was not possible to separate and recover the deodorizing member from the honeycomb structure, which was time-consuming.

[0040] Next, the frame 15 has perforations 155, which allows the third surface 151 to be opened wide. This makes it easy to peel the first sheet-like member 13 from the honeycomb structure 11, and consequently, easier to separate and recover the deodorizing member 12 from the honeycomb structure 11. Furthermore, the frame 15 has the function of covering the irregularities of the outer shape of the honeycomb structure 11, which is a major difference from the "frame" in the filter disclosed in Patent Document 1.

[0041] Thus, in this embodiment of the present invention, the filter 1 achieves the aforementioned excellent effects because the honeycomb structure 11, the first sheet-like member 13, the second sheet-like member 14, and the frame 15, each having specific characteristics, are closely related to and integrated with one another.
