Description

[Technical field]

[0001] The present disclosure relates to an air purifying device and an air direction adjusting device for an air conditioning outlet. [Background technology]

[0002] A technique for attaching a filter to the intake of an air conditioner has been disclosed (for example, Patent Document 1). The purpose of attaching a filter includes, for example, cleaning, disinfecting, antibacterial, or deodorizing the air blown out from the air conditioner. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2019 / 097647 Summary of the Invention [Problem to be solved by the invention]

[0004] When it is desired to improve the cleanliness of the air in the air-conditioned space, it is possible to use different types of filters. The air conditioner's intake port is one possible mounting location for these filters. Then, for example, it is possible to cut and paste multiple filters of different types and arrange them at the intake port. However, when cutting and pasting multiple filters of different types and arranging them at the intake port, the pasting work becomes cumbersome. In addition, it is possible that the air blown out from the air conditioner's outlet directly hits a user in the air-conditioned space, causing the user to feel uncomfortable. It is also possible that the components processed in the filter are unlikely to reach any direction other than the direction of the blown out air.

[0005] In one aspect, the present disclosure has been made in consideration of the above-mentioned situation, and its purpose is to provide technology that can easily improve the purification of air in an air-conditioned space and reduce the risk of the air blown out by the air conditioner directly hitting the user. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present disclosure employs the following configuration.

[0007] That is, an air purifying device according to one aspect of the present disclosure comprises a panel portion that is positioned in front of an air outlet from which conditioned air is blown out of an air conditioner, receives the air blown out from the air outlet, and has a plurality of holes penetrating in the thickness direction, an attachment portion that attaches the panel portion to the front of the air outlet, and a plurality of filters that are arranged to block each of the holes, and components capable of purifying the air are processed into the plurality of filters.

[0008] Here, the components capable of purifying air include components that suppress the function of impurities captured by the filter, components that suppress the function of impurities contained in the air that has passed through the filter, and components that can purify air include components that have a positive effect on the human mind.

[0009] According to this configuration, the blown air that has passed through each of the multiple filters is supplied to the space to be air conditioned, thereby increasing the effect of cleaning the air in the space to be air conditioned.

[0010] Also, according to this configuration, the purification of the blown air can be improved with a simple configuration in which the holes provided in the face plate portion are blocked with a filter.

[0011] In addition, according to this configuration, the speed of the blown air is reduced by passing through the filter. This reduces the direct exposure of the air blown out by the air conditioner to the user. This reduces the discomfort felt by the user in the air-conditioned space due to the strong wind. Furthermore, with this configuration, if the air conditioner is installed in the upper part of the room, and a component with a specific gravity heavier than air is processed into the filter, the component will sink to the lower part of the room. Therefore, the component is suitably diffused throughout the room.

[0012] Furthermore, according to this configuration, a portion of the blown air travels along the surface of the panel portion without passing through the filter. This blown air is then supplied to the space to be air-conditioned. This reduces the direct contact of the air blown by the air conditioner with the user. This reduces the discomfort felt by the user from being directly blown with air. Furthermore, a portion of the blown air travels along the surface of the panel portion without passing through the filter, and is then diffused into the room. This allows the components processed by the filter to be delivered in directions other than the blown direction of the blown air.

[0013] In the air purifying device according to the above aspect, at least two of the plurality of filters may each be processed with a different component capable of purifying air.

[0014] According to this configuration, the blown air that has passed through each of the multiple filters having different cleaning functions is supplied to the target space to be air conditioned, thereby increasing the effect of cleaning the air in the target space to be air conditioned.

[0015] The air purifying device according to the above aspect may further comprise a frame-shaped paper that is overlaid on the filter, the paper having a grip portion that extends outward from the area that overlaps with the filter and can be gripped with fingers.

[0016] According to this configuration, the filter can be easily removed by pinching the grip, making filter installation and replacement easy.

[0017] Furthermore, according to this configuration, the flexible filter is fixed to the frame-shaped paper. Therefore, the rigidity of the filter and paper combined is improved compared to the rigidity of the filter alone. This prevents the filter from being deformed during installation and replacement, making installation and replacement of the filter easier.

[0018] In the air cleaning device according to the above aspect, the holes may be spaced apart from each other by a predetermined distance.

[0019] According to this configuration, the air blown through each filter is prevented from mixing. Therefore, when components having different types of air purification functions are processed in each of the multiple filters, it is possible to provide different purification functions to the air-conditioned space.

[0020] The air purifying device according to the above aspect may further include protrusions that separate the areas of the face plate in which the holes are provided.

[0021] A portion of the air blown out from the air outlet does not pass through the filter and remains near the filter. Thus, the components processed in the filter are mixed into the remaining air. The protrusions prevent the remaining air containing such components from mixing with the remaining air containing components from another filter. The remaining air then passes over the panel portion and is supplied to the space to be air-conditioned. Thus, when components having different types of air purification functions are processed in each of the multiple filters, it is possible to provide different purification functions to the space to be air-conditioned.

[0022] In addition, according to this configuration, when the protrusion is formed integrally with the face plate, the decrease in flatness of the face plate is suppressed. Therefore, it is not necessary to seal the gap between the paper on which the filter is provided and the face plate with an adhesive or the like. Therefore, the occurrence of a gap between the paper on which the filter is provided and the face plate is suppressed. Therefore, the leakage of the blown air into the space to be air-conditioned through the gap without passing through the filter is easily suppressed. Therefore, the deterioration of the cleaning function of the configuration is easily suppressed. In addition, since there is no need to provide an adhesive between the paper on which the filter is provided and the face plate, the paper on which the filter is provided can be easily installed and replaced on the face plate.

[0023] Furthermore, according to this configuration, the protrusion can be used when fixing the filter to the face plate, which makes it easy to install the filter.

[0024] Furthermore, an air direction adjustment device for an air conditioning outlet according to one aspect of the present disclosure includes a panel portion that is disposed in front of the outlet from which conditioned air is blown out of an air conditioner, receives the air blown out from the outlet, and has a plurality of holes that penetrate in the thickness direction and are blocked by filters processed with components capable of purifying air, and an attachment portion that attaches the panel portion to the front of the outlet.

[0025] According to this configuration, when the multiple holes are blocked by the filters, the blown air that has passed through each of the multiple filters is supplied to the target space to be air conditioned, thereby increasing the effect of cleaning the air in the target space to be air conditioned.

[0026] Also, according to this configuration, the purification of the blown air can be improved with a simple configuration in which the holes provided in the face plate portion are blocked with a filter.

[0027] Furthermore, according to this configuration, when the multiple holes are blocked by the filter, the speed of the blown air is slowed down by passing through the filter. This reduces the direct contact of the blown air from the air conditioner with the user. This reduces the discomfort felt by the user in the air-conditioned space due to the strong wind. Furthermore, according to this configuration, when the air conditioner is installed at the top of the room, if a component with a specific gravity heavier than air is processed into the filter, the component will sink to the bottom of the room. Therefore, the component is suitably diffused in the room.

[0028] Furthermore, according to this configuration, when the multiple holes are blocked by the filter, part of the blown air travels along the surface of the panel portion without passing through the filter. This blown air is then supplied to the space to be air-conditioned. This reduces the direct contact of the air blown by the air conditioner with the user. This reduces the discomfort felt by the user from being directly exposed to the blown air. Furthermore, part of the blown air travels along the surface of the panel portion without passing through the filter, and is then diffused into the room. This allows the components processed by the filter to be delivered in directions other than the blown direction of the blown air. Effect of the Invention

[0029] According to the present disclosure, it is possible to easily improve the purification of air in a space to be air-conditioned, and to reduce the direct exposure of the air blown out by the air conditioner to a user. [Brief description of the drawings]

[Diagram 2] FIG. 2 is an example of an exploded perspective view of an air purifying device. [Diagram 3] FIG. 3 is an example of an enlarged view of a portion of a rib. [Figure 4] FIG. 4 shows an example of a state in which a filter is attached to a cleaning plate. [Diagram 5] FIG. 5 illustrates an outline of a plate according to a first modified example. [Figure 6] FIG. 6 illustrates an outline of a plate according to a second modified example. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] Hereinafter, an embodiment according to one aspect of the present disclosure (hereinafter, also referred to as "the present embodiment") will be described with reference to the drawings. However, the present embodiment described below is merely an example of the present disclosure in every respect. It goes without saying that various improvements and modifications can be made without departing from the scope of the present disclosure. In other words, in implementing the present disclosure, a specific configuration according to the embodiment may be appropriately adopted.

[0032] 1 shows a schematic diagram of an air purifying device 1 according to this embodiment installed in an air conditioner 50. Although a ceiling-embedded type of air conditioner 50 is shown as an example, the air conditioner 50 may be a wall-embedded type, a ceiling-suspended type, or a wall-mounted type.

[0033] The air purifier 1 includes a cleaning plate 2 (one example of a "face plate" in the present disclosure) and an arm 5 that positions the cleaning plate 2 in front of an air outlet 51 of an air conditioner 50. By positioning the cleaning plate 2 in this manner, the cleaning plate 2 can receive air blown out from the air outlet 51. The cleaning plate 2 is also provided with a hole 8, and the side of the hole 8 facing the air outlet 51 is covered by filters 10A, 10B, 10C, and 10D (details will be described later). In the following description, the filters 10A, 10B, 10C, and 10D may also be simply referred to as filters 10.

[0034] When air blown out from the air outlet 51 reaches the cleaning plate 2, a part of the blown air passes through the filters 10A, 10B, 10C, and 10D. Then, the blown air is purified by the filters 10A, 10B, 10C, and 10D, and then diffused into the room.

[0035] A hinge 3 is provided midway along the arm 5. The cleaning plate 2 is rotatable about the hinge 3 in the longitudinal direction. Thus, the angle of the cleaning plate 2 with respect to the blowing port 51 is changeable.

[0036] FIG. 2 is an example of an exploded perspective view of the air purifier 1. The purifier plate 2 shown in FIG. 2 is made of plastic or other synthetic resin, and its overall shape is a nearly rectangular shallow container. The purifier plate 2 has wall portions 14A and 14B that are erected at right angles to the main surface portion 13 on both longitudinal ends and the remaining side edge, except for one side edge of the main surface portion 13. The purifier plate 2 also has a curved portion 15 that is continuous with the main surface portion 13 and curves gently on the one side edge where the wall portions 14A and 14B are not formed. By providing such wall portions 14A and 14B, the air blown out from the outlet 51 of the air conditioner 50 is guided to the curved portion 15.

[0037] The cleaning plate 2 has holes 8 spaced at predetermined intervals in the longitudinal direction. The predetermined intervals are, for example, about several centimeters. The holes 8 are, for example, rectangular in shape, and there are four of them. The sum of the opening areas of the holes 8 is equal to or greater than half the surface area of ​​the main surface portion 13. The sum of the opening areas of the holes 8 may be less than half the surface area of ​​the main surface portion 13.

[0038] In addition, between the holes 8, ribs 6 are provided extending in the short direction of the main surface portion 13. In addition, ribs 7 are provided in the middle of the ribs 6, perpendicular to the ribs 6. The ribs 6 divide the main surface portion 13 into four regions in the longitudinal direction. The ribs 6 and 7 improve the overall rigidity of the cleaning plate 2 and the rigidity of the portions of the cleaning plate 2 between the holes 8. This prevents the flatness of the main surface portion 13 from decreasing. The ribs 7 are also provided on the wall portion 14A. The ribs 6 and 7 are examples of the "protrusions" of the present disclosure. Although the ribs 6 and 7 are formed integrally with the cleaning plate 2, the ribs 6 and 7 may be convex members separate from the cleaning plate 2.

[0039] Fig. 3 is an example of a partially enlarged view of the rib 7. As shown in Fig. 3, the rib 7 has a notch 71 in a part of the portion that contacts the main surface portion 13. The height of the notch 71 is such that the overlapping filter 10 and plate 11 (described later) can be inserted.

[0040] The air purifying device 1 also includes filters 10A, 10B, 10C, and 10D. The filters 10A, 10B, 10C, and 10D are made of, for example, a flammable nonwoven fabric, and cover the holes 8, respectively.

[0041] Each of the filters 10A, 10B, 10C, and 10D is processed with a different type of component that purifies the air. The component that purifies the air includes, for example, powder of Abies sachalinensis (an example of the "component capable of purifying the air" of the present disclosure) that has a deodorizing and fragrant function. The filter 10 processed with such a component can purify nitrogen dioxide, VOCs (Volatile Organic Compounds), and other pollutants. pounds) and has a cleaning effect such as removing the ammonia odor. Such a filter 10 suppresses the function of impurities captured by the filter. Also, such a filter 10 suppresses the function of impurities contained in the air that has passed through the filter. Also, such a filter 10 can be said to be processed with ingredients that have a positive effect on the human psyche.

[0042] At least one of the filters 10A, 10B, 10C, and 10D may be impregnated with a component contained in Abies sachalinensis (an example of an "air-purifying component" in the present disclosure). Such a filter 10 provides effects such as stress reduction, measures against hay fever, and forest bathing. In other words, such a filter 10 suppresses the function of impurities captured by the filter. Such a filter 10 also contains a component that has a positive effect on the human psyche. In addition to the components contained in Abies sachalinensis, examples of components that have a positive effect on the human psyche include aromas and the like.

[0043] Moreover, the component that purifies the air includes, for example, a component having an oxidation catalyst function (an example of the "component capable of purifying the air" of the present disclosure). The filter 10 processed with such a component exhibits cleaning effects such as anti-mold, anti-bacterial, and ammonia deodorization. In other words, such a filter 10 suppresses the function of impurities captured by the filter. Moreover, such a filter 10 suppresses the function of impurities contained in the air that has passed through the filter.

[0044] At least one of the filters 10A, 10B, 10C, and 10D may be a filter using Minerpa (registered trademark, an example of the "component capable of purifying air" in the present disclosure). Such a filter 10 provides cleaning effects such as deodorization, antibacterial properties, and suppression of virus activity. In other words, such a filter 10 suppresses the function of impurities captured by the filter. Also, such a filter 10 suppresses the function of impurities contained in the air that has passed through the filter.

[0045] At least one of the filters 10A, 10B, 10C, and 10D may be a filter using chlorine dioxide granules (an example of the "component capable of purifying air" of the present disclosure). Such a filter 10 exerts a cleaning effect such as sterilization, deodorization, or suppression of virus activity. In other words, such a filter 10 suppresses the function of impurities captured by the filter. Also, such a filter 10 suppresses the function of impurities contained in the air that has passed through the filter.

[0046] Furthermore, the components processed into the filter 10 may be components that purify air other than those mentioned above. Furthermore, the filter 10 may be non-flammable, and the material thereof is not limited to non-woven fabric.

[0047] The air purifying device 1 also includes a plate 11. The plate 11 is frame-shaped and made of, for example, paper. One side of the plate 11 is provided with an adhesive for fixing the filter 10 to the plate 11. One side of the plate 11 is provided with a gripping portion 12 that extends in a direction away from the center and can be gripped with fingers. Note that the plate 11 does not necessarily need to be provided with an adhesive, and the filter 10 may be clamped by, for example, bending the plate 11.

[0048] The air purifying device 1 also has a hinge 16 at the connection between the arm 5 and the cleaning plate 2. The cleaning plate 2 can rotate around the hinge 16 in the longitudinal direction. Therefore, the angle of the cleaning plate 2 relative to the air outlet 51 can also be changed by the hinge 16. The arm 5, hinge 3 (see FIG. 1), and hinge 16 are an example of an "attachment part" in the present disclosure.

[0049] FIG. 4 shows an example of a state in which the filters 10A, 10B, 10C, and 10D are attached to the cleaning plate 2. In order to attach the filters 10A, 10B, 10C, and 10D to the cleaning plate 2 as shown in FIG. 4, the filters 10A, 10B, 10C, and 10D are first fixed to one side of the plate 11. Next, the gripping portion 12 of the plate 11 (hereinafter referred to as a cartridge) to which the filters 10A, 10B, 10C, and 10D are fixed is gripped by the user's fingers. Then, the cartridge is moved so as to slide on the main surface portion 13 from the curved portion 15 toward the wall portion 14B. At this time, the cartridge is moved so that the cartridge fits into the notch 71 of the rib 7. In this way, the filters 10A, 10B, 10C, and 10D are installed in the respective areas of the main surface portion 13 partitioned by the rib 6. It should be noted that the cartridge may be bent and fitted into the notch 71 of the rib 7, rather than being slid on the main surface portion 13. In this manner, the cartridge is easily positioned by the rib 7 and fixed onto the main surface portion 13.

[0050] [Actions and Effects] According to the air purifying device 1 as described above, the blown air that has passed through the filters 10A, 10B, 10C, and 10D having a plurality of different types of cleaning functions is supplied to the space to be air-conditioned. This increases the effect of cleaning the air in the space to be air-conditioned. In addition, holes 8 are provided on more than half of the main surface portion 13. This means that most of the air blown out from the air outlet 51 passes through the holes 8 (with the filters 10). This means that a large amount of blown air that has been cleaned by the filters 10 is supplied to the space to be air-conditioned. This also increases the effect of cleaning the air in the space to be air-conditioned.

[0051] Moreover, according to the air purifying device 1 as described above, the purification of the blown air can be improved with a simple configuration in which the holes 8 provided in the cleaning plate 2 are blocked with the filters 10.

[0052] Moreover, according to the air purifying device 1 as described above, the holes 8 are provided at intervals of about several centimeters. Therefore, the filters 10A, 10B, 10C, and 10D are arranged at intervals of about several centimeters. Therefore, even if the filter 10A has an aroma function and the filter 10B arranged next to the filter 10A has a deodorizing function, the air blown through the filters 10A and 10B is prevented from mixing. Therefore, it is possible to provide different cleaning functions to the air-conditioned space without the different cleaning functions canceling each other out.

[0053] Furthermore, according to the air purifying device 1 as described above, the speed of the air blown out from the air outlet 51 of the air conditioner 50 is slowed down by passing through the filter 10. This reduces the direct blowing of the air from the air conditioner 50 onto the user. This reduces the discomfort felt by the user in the air-conditioned space due to exposure to strong winds.

[0054] According to the air purifying device 1 as described above, a wall portion 14A is erected along the short side of the main surface portion 13. A wall portion 14B is erected along the long side of the main surface portion 13, which is an edge in the long side of the main surface portion 13 and is opposite to the curved portion 15. Ribs 6 are erected along the short side of the main surface portion 13 between the filters 10A, 10B, 10C, and 10D. Thus, the blown air that hits the main surface portion 13 is prevented from flowing in the long axis direction of the main surface portion 13, and travels along the surface of the main surface portion 13 in the short axis direction. Then, the blown air passes over the curved portion 15 and is supplied to the space to be air-conditioned. This reduces the direct blown air blown to the user in the space to be air-conditioned. This reduces the discomfort felt by the user when the user is directly exposed to the wind. A part of the blown air does not pass through the filter 10, but travels along the surface of the main surface portion 13, and then is diffused into the room. Therefore, the components processed by the filter 10 are delivered to directions other than the blowing direction of the blown air.

[0055] Moreover, the blown air stagnating near each of the filters 10A, 10B, 10C, and 10D contains components processed in each of the filters 10A, 10B, 10C, and 10D. Moreover, each of the filters 10A, 10B, 10C, and 10D is partitioned by the rib 6. Therefore, the stagnant air containing the components processed in any one of the filters 10A, 10B, 10C, and 10D is prevented from mixing with the stagnant air containing the components processed in another filter 10. Then, the stagnant air travels in the direction of the curved portion 15 of the main surface portion 13 (in the long axis direction) and is then supplied to the space to be air-conditioned. Therefore, the different cleaning functions are not cancelled out and the air is supplied to the space to be air-conditioned.

[0056] Moreover, the air purifying device 1 as described above has a simple structure. The air purifying device 1 is disposed in front of the air outlet 51 of the air conditioner 50. Therefore, the pressure loss of the air sucked into the air conditioner 50 is easily reduced while the cleaning effect is increased.

[0057] Moreover, according to the air purifying device 1, the cartridge (filter 10 and plate 11) is easily fixed to the main surface portion 13 by being fitted into the notch 71 of the rib 7. This makes it easy to install and replace the filter 10. Furthermore, the plate 11 is provided with a gripping portion 12 that can be held by fingers. Therefore, when it is desired to replace the filter 10, it is only necessary to pinch the gripping portion 12 and remove it. This also makes it easy to install and replace the filter 10. Furthermore, the filter 10 is made of nonwoven fabric, and the plate 11 is made of paper. Therefore, the removed filter 10 and plate 11 can be disposed of as combustible waste. In other words, the filter 10 can be easily replaced and disposed of.

[0058] Furthermore, according to the air purifying device 1, the filter 10 is flexible because it is made of nonwoven fabric, but the filter 10 is fixed to the frame-shaped plate 11 made of paper. Therefore, the rigidity of the cartridge in which the filter 10 and the plate 11 are integrated is improved compared to the rigidity of the filter 10 alone. Therefore, deformation of the filter 10 during installation and replacement is suppressed. Therefore, it can be said that installation and replacement of the filter 10 is easy.

[0059] Moreover, according to the air purifying device 1 described above, the ribs 6 and 7 prevent the flatness of the main surface portion 13 from decreasing. Therefore, the occurrence of gaps between the plate 11 and the main surface portion 13 is prevented. Furthermore, by ensuring the flatness of the main surface portion 13, the occurrence of gaps between the plate 11 and the main surface portion 13 is prevented without bonding the plate 11 and the main surface portion 13 with an adhesive or the like. Therefore, the leakage of the blown air from the gap into the space to be air-conditioned without passing through the filter 10 is easily prevented. Therefore, the deterioration of the purification function of the blown air is easily prevented. Furthermore, since there is no need to provide an adhesive between the plate 11 and the main surface portion 13, the occurrence of gaps between the plate 11 and the main surface portion 13 is prevented. It can be easily installed and replaced on the surface portion 13.

[0060] Moreover, according to the air purifying device 1, the air conditioner 50 is installed on the ceiling of the room. Therefore, if chlorine dioxide, which has a specific gravity heavier than air, is processed into the filter 10, the chlorine dioxide will settle to the bottom of the room. Therefore, the chlorine dioxide will be suitably diffused in the room.

[0061] [Variation 1] FIG. 5 illustrates an outline of a plate 11A according to a first modified example. FIG. 5(A) is an example of a state before the plate 11A is assembled. FIG. 5(B) is an example of a state in which the plate 11A is assembled with the filter 10 installed thereon. The plate 11A is made of paper, similar to the plate 11. As shown in FIG. 5(A), the plate 11A has holes 21A and 21B. The plate 11A has semi-arc-shaped notches 17 and 18 on the upper part thereof. Meanwhile, the plate 11B has a claw 19 on the lower part thereof.

[0062] The filter 10 is placed on the plate 11A so as to overlap the hole 21A. After that, the plate 11A is folded and assembled as shown by the arrow in FIG. 5(A) to form the shape shown in FIG. 5(B). When the plate 11A is assembled, the notch 17 is pushed to the back side of the paper. In this way, a gripping portion 12A that can be gripped by fingers is completed as shown in FIG. 5(B). Also, the claw 19 is fitted into the notch 18 as shown in FIG. 5(B). By assembling in this way, the filter 10 is sandwiched between the plate 11A and easily fixed without using adhesive or the like. Then, the plate 11A to which the filter 10 is fixed is fixed to the main surface portion 13 by fitting it into the notch 71 as in the above-mentioned embodiment. When fixed to the main surface portion 13, the surface 110 of the plate 11A becomes the upper surface. Also, a striped line may be applied to a part of the plate 11.

[0063] [Variation 2] FIG. 6 illustrates an outline of the plate 11B and the plate 11C according to the second modification. In the plate 11B shown in FIG. 6(A), a strip of paper 20 is provided so as to cover a part of the hole 21A. By providing the strip of paper 20 in this manner, the amount of the blown air that passes through the filter 10 and passes through the hole 21A is limited. Therefore, the blown air is prevented from hitting a user in the air-conditioned space directly and causing discomfort to the user. In addition, the strip of paper 20 receives the filter 10, and the filter 10 is prevented from being pushed by the blown air and bending and falling out of the hole 21A. Thus, the fixation of the filter 10 is strengthened. In addition, in the plate 11C shown in FIG. 6(B), the strip of paper 20 is also provided in the hole 21B. According to such a plate 11C, in addition to the function of the plate 11B, the amount of the blown air that hits the filter 10 is limited. Therefore, the blown air is prevented from hitting a user in the air-conditioned space directly and causing discomfort to the user. The form formed by the belt-shaped paper 20 is not limited to the examples shown in Figures 6(A) and 6(B). For example, a cross-shaped frame may be formed by the belt-shaped paper 20, and a part of the holes 21A and 21B may be blocked.

[0064] [Other variations] Although the plate 11 described above is made of paper, the material of the plate 11 is not limited to paper. Furthermore, the plate 11 does not necessarily have to be provided with the gripping portion 12. Furthermore, the plate 11 does not necessarily have to be provided, and the filter 10 may be directly fixed to the edge of the hole 8 with an adhesive or the like, without the plate 11 being interposed therebetween, and cover the hole 8.
