BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
Figure 1 shows an example of a filter body 1 of the invention of claim 1, the filter body 1 is formed in a plate shape of a porous material or the like. A V-groove 2a as shown in FIG. 2 is formed on the front surface (both surfaces) of the filter main body 1, and the separating portion 2 is provided on the filter main body 1 by the V-groove 2a. Separating portions 2 formed by V grooves 2a are provided in the filter body 1 in the vertical and horizontal directions.
[0009]
This filter body 1, by folding the filter body 1 along the cut-off portion 2 by V grooves 2a as shown in FIG. 1 (b), disconnect the filter body 1 in a plurality pieces as shown in FIG. 1 (c) The air purifier can be divided into a size suitable for the type of the air purifier and can be attached to the air purifier.
[0010]
FIGS. 3 and 4 show another example of the filter body 1 according to the first embodiment of the present invention, in which a granular odor adsorbent 16 is placed at a plurality of positions on a nonwoven fabric 15 and another nonwoven fabric 15 is placed on the nonwoven fabric 15. The filter body 1 is manufactured by sandwiching the odor adsorbent 16 between the two nonwoven fabrics 15 and 17 by laminating the nonwoven fabric 17 and bonding the nonwoven fabrics 15 and 17 at a position surrounding the odor adsorbent 16. . As the odor adsorbent 16, activated carbon or a substance in which an agent for decomposing odorous substances is carried on a carrier such as activated carbon can be used. Then, perforations 2b are inserted into the nonwoven fabrics 15 and 17 at locations where the nonwoven fabrics 15 and 17 are adhered so as to surround the odor adsorbent 16, and the cut-off portion 2 is provided on the filter body 1. Separating portions 2 formed by perforations 2b are provided in the filter body 1 in the vertical and horizontal directions.
[0011]
This sheet-like filter body 1, by cutting the filter body 1 along the cut-off portion 2 by perforation 2b, it is those that can be divided disconnect the filter body 1 in a plurality pieces, air purifiers It can be mounted on an air purifier in a size suitable for the model.
[0012]
Figure 5 shows an example of an embodiment of the invention of claim 1, by attaching paste the frame 3 on one side of a sheet-like filter body 1, are to be prepared filter A. Since the filter body 1 formed in a sheet shape by the nonwoven fabrics 15 and 17 as shown in FIGS. 3 and 4 has no stiffness, the filter A can be easily handled by attaching the frame 3 to the filter body 1. Things. The frame body 3 can be formed of a material having a strong stiffness such as a resin molded article, paper, cardboard, or the like, and the frame body of the frame body 3 is provided on the filter body 1 with perforations 2b or the like. Since the frame can be superimposed on the separating portion 2, a frame separating portion 4 is provided on the frame of the frame body 3 along the separating portion 2. The frame separating portion 4 can be formed by a V groove 4a as shown in FIG.
[0013]
In this device, by cutting both the separating portion 2 of the filter main body 1 and the frame separating portion 4 of the frame body 3, the filter main body 1 and the frame body 3 can be divided while being attached to each other. Yes, the size can be adapted to the model of the air purifier and can be attached to the air purifier.
FIG. 7 shows an example of the embodiment of the third aspect of the present invention, in which a plurality of (two in FIG. 7) filter pieces 5 and 6 are attached to the frame body 3 by bonding, and The filter A is formed from the filter body 1 composed of the filter pieces 5 and 6 and the frame 3. Each of the filter pieces 5 and 6 may be, for example, one having a high performance of deodorizing a nitrogen-based odor such as ammonia, and the other filter piece 6 having a high performance of deodorizing a formaldehyde odor such as formaldehyde. Are formed as different types of deodorizing odor components. Each of the filter pieces 5 and 6 is provided with a separating portion 2 formed by a perforation 2b or the like, so that the separating portion 2 provided on the filter piece 5 and the separating portion 2 provided on the filter piece 6 are continuous as a straight line. Each of the filter pieces 5 and 6 is disposed. Further, a frame separating portion 4 formed by a V-groove 4a or the like is provided along the separating portion 2 in the frame of the frame 3 to be overlapped with the separating portion 2 of the filter pieces 5, 6. The joint between them is joined to a wide vertical frame 3a at the center of the frame 3.
[0014]
The filter A thus formed as shown in FIG. 8A is a combination of the filter pieces 5 and 6 for deodorizing different types of odor components. 6 can be efficiently deodorized. Then, the filter pieces 5, 6 and the frame 3 were cut along the separating section 2 and the frame separating section 4, respectively, so that the filter pieces 5, 6 and the frame 3 were bonded together as shown in FIG. The air purifier can be divided as it is, and can be mounted on the air purifier in a size suitable for the type of the air purifier.
[0015]
FIG. 9 shows an embodiment of the third aspect of the present invention, in which a filter A is provided with a joining means 8 for attaching to a device for air cleaning. For example, it is possible to provide an engagement protrusion 8a on the frame 3 of the filter A and form the joining means 8 with the engagement protrusion 8a. On the other hand, as shown in FIG. 9B, an engagement hole 20 corresponding to the engagement protrusion 8a of the filter A is provided in a frame 19 around the existing filter 18 attached to the air purifying device. The existing filter 18 is a member attached to the air purifying device and is detachably attached to the air purifying device. The existing filter 18 is formed by fixing a deodorizing filter 21 such as an activated carbon filter in a frame portion 19. Reference numeral 22 denotes a handle provided on a side surface of the frame 19 of the existing filter 18.
[0016]
In this case, as shown in FIG. 10, the joining means 8 formed by the engaging projection 8 a of the filter A is inserted into the engaging hole 20 of the existing filter 18 so as to be able to be pulled out and removed so as to engage with the existing filter 18. The filter A can be detachably joined and attached, and when the existing filter 18 is attached to the air purifying device, the filter A can be attached to the air purifying device at the same time. FIG. 11 shows another example of the embodiment of the fourth aspect of the present invention, in which the joining means 8 is formed by fastening tapes 8b and 8c commonly called magic tapes. Of the pair of free fastening tapes 8b and 8c, one fastening tape 8b is attached to the back surface of the filter A, and the other fastening tape 8c is attached to the frame 19 of the existing filter 18 by bonding or the like. The filter A is detachably joined to and attached to the existing filter 18 by engaging the tapes 8b and 8c. The joining means 8 can be further formed using a double-sided adhesive tape or the like.
[0017]
FIG. 12 shows an example of the embodiment of the fourth aspect of the present invention, in which a frame 3 used by being attached to the filter main body 1 is provided with a hole 9 for air passage. When the filter A is formed by attaching the frame body 3 to the filter body 1, the area through which air passes through the filter body 1 is reduced by the area of the frame body 3, resulting in a pressure loss during the passage of air. By providing the air holes 9 in the frame 3, air can pass through the holes 9 and pass through the filter body 1 in the portion of the frame 3, and the pressure loss when air is passed through the frame 3 is reduced. It can be reduced. The shape of this hole 9 is not limited to a square hole as shown in FIG. Alternatively, the frame 3 may be formed of a mesh, and the holes 9 may be formed as meshes.
[0018]
