Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air purifying filter that allows air to pass through and removes dust in the air, and an air treatment device using the same.
[0002]
[Prior art]
For example, as shown in FIG. 6, the air purification filter 10 is installed in a part or all of the passage of the air 21 that is sucked and exhausted by the blower 20 to remove dust in the air and perform sterilization. There is an air treatment device 100 as an air cleaning device.
[0003]
For example, as shown in FIG. 7, the air passage portion of the air cleaning filter 10 used in such an application includes a nonwoven fabric 11a made of a charged fiber, antibacterial properties, and antiviral properties (hereinafter collectively referred to as antibacterial properties). And a non-illustrated non-illustrated nonwoven fabric 11b attached with chlorhexidine gluconate having a large surface area by laminating a flat nonwoven fabric 11c made of a double nonwoven fabric and a corrugated nonwoven fabric 11d made of the double nonwoven fabric. It is created by forming it into a honeycomb shape (thickness: about 5 to 10 mm).
[0004]
Therefore, the air sucked and exhausted by the blower 20 is filtered out by dust and oil (steam) by the nonwoven fabrics 11a and 11b of the air cleaning filter 10, and dust that is fine enough to pass between the fibers of the nonwoven fabric is charged fiber. Since there is a nonwoven fabric 11a made from the above, fine dust that is easily charged is attracted to the nonwoven fabric 11a by the Coulomb force and removed. Further, since chlorohexidine gluconate having antibacterial properties is provided on the nonwoven fabric 11b, it does not grow even if bacteria adhere to the dust or oil that is filtered and adhered to the nonwoven fabrics 11a and 11b.
[0005]
However, the air purifying filter having the above-described structure is antibacterial by artificial chlorhexidine gluconate and does not satisfy the natural taste of consumers.
Therefore, the present inventors have previously described the honeycomb dust collection filter 11 that is formed in a honeycomb shape so as to have a large surface area using a nonwoven fabric or the like as shown in FIGS. 8 and 9. In addition, an air purifying filter formed by disposing a deodorizing filter 12 formed in a sheet form by dispersing activated carbon in porous urethane foam, and further disposing a non-woven fabric 13 made of charged fibers impregnated with polyphenol 14 behind it. 10 was proposed (Japanese Patent Application No. 11-152883).
[0006]
[Problems to be solved by the invention]
However, in the air purification filter 10 having the configuration shown in FIGS. 8 and 9, since the honeycomb dust collection filter 11, the deodorization filter 12, and the nonwoven fabric 13 are all insufficient in rigidity, the air purification filter 10 is generally soft, for example, one end. When it has, there is a problem that it is easy to bend greatly and it is difficult to handle in work such as filter replacement.
The first object of the present invention is not only to remove dust in the air, but also to provide a deodorizing action, antibacterial and antiviral properties, and to make the filter itself rigid and difficult to bend to replace the filter. The object of the present invention is to provide an air purifying filter that is easy to handle in operation, and a second object of the present invention is to provide an air treatment device using the air purifying filter.

A first embodiment of the present invention will be described in detail based on FIG. 1 and FIG.
The air purifying filter 10 of the first embodiment shown in FIGS. 1 and 2 includes a flat nonwoven fabric 11e made of charged fibers (for example, charged fibers made of polyolefin resin such as polyethylene and polypropylene) and a wave made of the same charged fibers. Behind the honeycomb dust collecting filter 11 formed in a honeycomb shape by laminating the plate-like nonwoven fabric 11f,
A deodorizing filter 12 made of porous urethane foam carrying activated carbon is laminated, and a rigid resin net 15 carried by attaching, adhering, applying and impregnating polyphenol 14 behind the deodorizing filter 12. For example, known hot melt type adhesives 16 (for example, thermoplastic resins such as polyvinyl acetate, polyvinyl butyral, acrylic resin, polyisoprene polyamide, ethylene-vinyl acetate copolymer, ethylene-acrylic ester copolymer, It is formed by bonding using a terpene resin, a rosin derivative, a hot melt type adhesive composed of natural resin such as rubber, and the like. The honeycomb dust collecting filter 11 and the deodorizing filter 12 are each usually formed to a thickness of about 5 to 10 mm, and the rigid resin net 6 is usually formed to a thickness of about 0.5 to 5 mm.
[0011]
The polyphenol 14 supported on the resin net 15 has a deodorizing action on methyl mercabtan (cause of bad breath) and trimethylamine (fish odor component).
And as this polyphenol 14, for example, about 50% of proanthocyanidins that have been shown to have strong antioxidant action and suppress the occurrence of heart diseases, gastric ulcers, and even cancer, suppression of active oxygen and carcinogenicity About 30% of chlorogenic acid, which inhibits the production of substances (nitrosamines), about 10% of phlorizin, which reduces the symptoms of diabetes, suppresses the generation of lipid peroxides and removes cholesterol and neutral fat in the blood Extracted and prepared from immature fruits of apples containing about 10% of certain epicatechins and about 5% of catechins that have arteriosclerosis, anti-aging, and carcinogenesis-preventing effects and strong bactericidal action comparable to antibiotics. Natural polyphenols having strong antibacterial properties (for example, Applephenon manufactured by Nikka Whiskey Co., Ltd.) are used.
[0012]
[Second Embodiment]
The resin net 15 carrying the polyphenol 14 is coupled to the back of the honeycomb dust collection filter 11 as shown in FIGS. 1 and 2, and is disposed in front of the honeycomb dust collection filter 11 as shown in FIG. May be.
[0013]
[Third Embodiment]
Further, as shown in FIG. 4, the entire dust collection filter 11 and the deodorizing filter 12 may be wrapped and disposed both in front of the dust collection filter 11 and behind the deodorizing filter 12.
[0014]
[Fourth Embodiment]
Further, as shown in FIG. 5, the resin net 15 may be sandwich-stacked with the honeycomb dust collecting filter 11 and the deodorizing filter 12.
3 to 5, the same components as those of the air purification filter shown in FIGS.
[0015]
And in the air purifying filter 10 of the said 2nd Embodiment, the resin-made net | networks 15 are integrated | attached on the front surface of the honeycomb dust collection filter 11, and are integrated.
In the air purifying filter 10 of the third embodiment, the overlapping portions of the resin net 15 are integrated with the dust collecting filter 11 and the deodorizing filter 12 by bonding, fusing or sewing.
Further, in the air purification filter 10 of the fourth embodiment, the resin net 15 is sandwiched between the honeycomb dust collection filter 11 and the deodorizing filter 12 and bonded or fused to be laminated and integrated.
[0016]
When the air purification filter 10 of the first embodiment is installed in an air passage such as the air treatment device 100 shown in FIG. 6, the air 21 sucked and exhausted by the blower 20 is first passed through the honeycomb dust collection filter 11. The dust and oil (vapor) contained in the air 21 are removed, and a relatively large matter is removed here, and the honeycomb dust collecting filter 11 is made of a charged fiber. Dust is attracted to the honeycomb dust collection filter 11 by the Coulomb force and is surely removed.
[0017]
The air 21 from which dust, oil, and the like have been removed subsequently passes through the deodorizing filter 12, and fine dust, oil, and the like that have not yet been removed contained in the air 21 pass through the urethane foam gap of the deodorizing filter 12. The odor component contained in the air 21 is adsorbed and removed by the activated carbon dispersedly supported on the deodorizing filter 12.
[0018]
The air 21 from which dust, fats and oils, odorous components, and the like have been removed through the deodorizing filter 12 subsequently passes through the resin net 15.
Even if bacteria adhere to the dust or oil removed by the honeycomb dust collecting filter 11 or the deodorizing filter 12, the antimicrobial action of the polyphenol 14 carried on the resin net 15 suppresses the propagation of bacteria, and the indoor Bacterial contamination of the blown out air 21 is prevented.
[0019]
Further, since the polyphenol 14 has a deodorizing action, the air deodorized by the deodorizing filter 12 can be further deodorized.
[0020]
Thus, the air purifying filter 10 of the first embodiment not only removes dust and oil in the air, but also has a deodorizing action, antibacterial / antiviral properties, and a rigid resin net 15. Since they are laminated, rigidity is imparted to the air cleaning filter 10 itself, and it becomes difficult to bend even if it has an end, and it is very easy to handle in operations such as filter replacement.
[0021]
In the air purifying filter 10 of the second embodiment, since the resin net 15 carrying the polyphenol 14 is disposed in the part where the air 21 first passes, the air is deodorized in this part. Even if bacteria adhere to the dust or oil removed by the honeycomb dust collecting filter 11 or the deodorizing filter 12, the antimicrobial action of the polyphenol 14 carried on the resin net 15 suppresses the growth of the bacteria and blows it out indoors. Bacterial contamination of the air 21 is prevented. Further, since the rigid resin net 15 is laminated, the air purification filter 10 itself is given rigidity, and even if it has an end, it is difficult to bend, and it is very easy to handle in operations such as filter replacement.
[0022]
Moreover, in the air purification filter 10 of the said 3rd Embodiment, while having the same effect as the air purification filter 10 of the 1st-2nd embodiment, the proliferation of bacteria is suppressed in two places before and behind the air purification filter 10. In addition, there is an advantage that deodorization of air is achieved.
[0023]
Moreover, in the air purifying filter 10 of the said 4th Embodiment, while having the same effect as the air purifying filter 10 of the 1st-3rd embodiment, the resin nets 15 are the honeycomb dust collection filter 11 and the deodorizing filter 12. Since the sandwich lamination is integrated, there is an advantage that the growth of bacteria in the honeycomb dust collecting filter 11 and the deodorizing filter 12 is effectively suppressed, and the air is deodorized.
[0024]
In addition, since this invention is not limited to the said embodiment, various deformation | transformation implementation is possible in the range which does not deviate from the meaning as described in a claim.
[0025]
The air treatment apparatus of the present invention may be an air conditioner, a warm air heater, or the like installed in an air passage where the air purification filter having the above-described configuration connects the intake port and the exhaust port.
[0026]
