Description
本発明は、空気浄化装置などの機械による強制給排気による空気処理装置に装着使用されるエアフィルタ、特に波板状のフィルタ材を有する脱臭フィルタに関するものである。 The present invention relates to an air filter that is mounted and used in an air treatment device that uses forced air supply and exhaust by a machine such as an air purification device, and more particularly to a deodorization filter having a corrugated filter material.
近年、東アジア内陸部の砂漠、乾燥地域からの砂塵（黄砂）や、ＰＭ２．５、スギ、ヒノキなどの花粉の飛散、また、インフルエンザ等のウイルスによる感染症の流行が健康へ及ぼす影響から、窓を開けた室内空気の換気に代わり、空気清浄機やエアコンを用いて室内空気を浄化、調温、調湿する生活環境が多く見られる。家庭や職場、自動車などの空間の快適性向上の機能に対する市場要望は強く、空気浄化装置の普及が進んでいる。 In recent years, from the impact on the health of deserts in East Asia, dust (yellow sand) from dry areas, the scattering of pollen such as PM2.5, cedar, cypress, and infections caused by viruses such as influenza, There are many living environments in which indoor air is purified, temperature-controlled, and humidity-controlled using air purifiers and air conditioners instead of ventilation of indoor air with windows open. The market demand for the function of improving the comfort of spaces such as homes, workplaces, and automobiles is strong, and the use of air purifiers is progressing.
普及とともに、空気浄化装置に要求される性能は年々高性能化している。一方で、特に家庭用の空気清浄機などでは、省スペース性、意匠性も重要視されるようになっており、従来の箱型だけでなく、円筒形状や円錐形状などの形状の空気浄化装置が上市されている。 With the spread, the performance required for air purification devices has been increasing year by year. On the other hand, especially in home air purifiers, space saving and design are also regarded as important, and air purification devices not only in the conventional box shape but also in the shape of a cylinder or cone Is on the market.
このようなニーズに従い、空気浄化装置に内蔵されるエアフィルタに対しても同様に、高性能化だけでなく、空気浄化装置の設計を妨げない省スペース性や、丸形状や円筒形状など特殊な形状も要求されている。 In accordance with these needs, the air filter built in the air purifier is not only improved in performance, but also has special features such as space saving that does not hinder the design of the air purifier and round and cylindrical shapes. A shape is also required.
エアフィルタの機能は、集塵、脱臭用、抗菌、抗ウイルス、抗アレルゲン、加湿、蒸散、除湿、芳香など様々である。エアフィルタの形状としては、フィルタ材を波板状に折り曲げた、いわゆるプリーツフィルタが知られている。フィルタ材を波板状とすることで、粉塵や臭気の保持容量が向上して長寿命となり、通過風速を遅くして粉塵や臭気の捕捉能力を向上することができる。 The air filter has various functions such as dust collection, deodorization, antibacterial, antiviral, antiallergen, humidification, transpiration, dehumidification, and aroma. As a shape of the air filter, a so-called pleated filter in which a filter material is bent into a corrugated plate shape is known. By making the filter material into a corrugated plate shape, the dust and odor retention capacity is improved and the service life is extended, and the passing air speed is slowed to improve the dust and odor capturing ability.
様々な機能が要求されるエアフィルタについて、高性能化、省スペース性を実現するために、例えば、プリーツフィルタについて、集塵用フィルタと脱臭フィルタを一体化したエアフィルタ（例えば、特許文献１及び２参照）が開示されている。 For air filters that require various functions, in order to achieve high performance and space saving, for example, for pleated filters, an air filter in which a dust collecting filter and a deodorizing filter are integrated (for example, Patent Document 1 and 2).
特許文献１及び２の場合、波板状としたフィルタ材の構造保持と、フィルタ材を通過しない空気の通路を塞ぐため、いずれも、板状の樹脂、紙、不織布や金属などを含む枠材やケースが必要である。その結果、効率的な製造工程を考えると、エアフィルタの形状が実質上、直方体に限られており、空気浄化装置の設計の自由度や意匠性向上に制限が生じる課題があった。 In the case of Patent Documents 1 and 2, in order to close the structure of the corrugated filter material and to block the passage of air that does not pass through the filter material, the frame material includes plate-like resin, paper, nonwoven fabric, metal, etc. Or a case is needed. As a result, when an efficient manufacturing process is considered, the shape of the air filter is substantially limited to a rectangular parallelepiped, and there is a problem that the degree of freedom in designing the air purification device and the improvement in design are limited.
一方、直方体でないプリーツフィルタとして円筒形のプリーツフィルタも開示されている（例えば、特許文献３参照）。このように、比較的複雑な製造工程を経ることで、様々な形状のエアフィルタを供給することはできる。しかしながら、構造が固定され、形状は変化できないため、エアフィルタの輸送や保管時に、その特徴的な構造から、容積が嵩み、輸送や保管の効率が著しく悪くなる課題があった。 On the other hand, a cylindrical pleated filter is also disclosed as a pleated filter that is not a rectangular parallelepiped (see, for example, Patent Document 3). In this way, air filters having various shapes can be supplied through a relatively complicated manufacturing process. However, since the structure is fixed and the shape cannot be changed, there is a problem in that the volume is increased due to the characteristic structure during transportation and storage of the air filter, and the efficiency of transportation and storage is remarkably deteriorated.
本発明の課題は、搭載される空気浄化装置の設計自由度を妨げず、意匠性向上に制限を生じさせない、脱臭フィルタを提供することである。 An object of the present invention is to provide a deodorizing filter that does not impede the degree of freedom of design of an air purification device to be mounted and does not limit the improvement in design.
上記課題は、柔軟で形状が可変な脱臭フィルタによって解決される。具体的には、ケースや枠材を使用しない、波板状で通気性を有する第一のフィルタ材と、第一のフィルタ材の一面側の谷部の空間に充填される粒状脱臭剤と、第一のフィルタ材の上記一面側の山部の頂部に固定されて、粒状脱臭剤を被覆し、通気性を有する第二のフィルタ材とを備えた脱臭フィルタにおいて、第一のフィルタ材と第二のフィルタ材とで構成される三角形状の開口部が樹脂で封鎖されていて、枠材を用いていないことを特徴とする脱臭フィルタ、さらには前記樹脂がホットメルト樹脂である前述の脱臭フィルタで解決される。 The above problem is solved by a deodorizing filter that is flexible and has a variable shape. Specifically, a first filter material that is corrugated and does not use a case or a frame material, and a granular deodorant that is filled in the space of the valley on one side of the first filter material, In the deodorizing filter that is fixed to the top of the peak portion on the one surface side of the first filter material, covers the granular deodorant, and has a second filter material having air permeability, the first filter material and the first filter material A deodorizing filter characterized in that a triangular opening composed of two filter materials is sealed with a resin and no frame material is used , and further, the deodorizing filter described above, wherein the resin is a hot-melt resin Will be solved.
本発明により、搭載される空気浄化装置の設計自由度を妨げず、意匠性向上に制限を生じさせない脱臭フィルタを提供することができる。 According to the present invention, it is possible to provide a deodorizing filter that does not impede the degree of freedom in design of an air purification device to be mounted and does not limit the improvement in design.

For example, in the case of activated carbon, it is determined by calculating the deodorizing performance determined by JEM 1467-1995 or the like and calculating the durability days.
粒状脱臭剤２の形状は、球、円柱、直方体など成型してあっても構わないし、大粒径のものを砕いたそのままの形状でも構わない。大きさは、第一のフィルタ材１及び第二のフィルタ材３を突き抜けて脱落しない必要があり、最大長が０．２ｍｍ以上であることが好ましい（６０ＭＥＳＨ）。 The shape of the granular deodorizer 2 may be a sphere, a cylinder, a rectangular parallelepiped or the like, or may be a shape obtained by pulverizing a large particle size. The size needs to penetrate the first filter material 1 and the second filter material 3 and not fall off, and the maximum length is preferably 0.2 mm or more (60MESH).
第一のフィルタ材１を波板状に加工する方法としては、折り曲げ加工を、山・谷、交互に機械的に連続して折り畳む方法；フィルタ材上の山部の稜線（谷部の谷筋）に相当する位置に、線上の叩き跡を設け、叩き跡を折り線として波板状に折り畳む方法；既定の波型のギヤに挟み込み、波板状に成型する方法、などが挙げられるが、これに限定されない。いずれの方法においても、波板状に加工しやすくする目的で熱や圧力をかけることができる。 As a method of processing the first filter material 1 into a corrugated plate shape, a bending process is a method in which peaks and valleys are alternately and continuously folded; a ridge line (valley in the valley) on the filter material; There is a method of forming a tapping trace on the line at the corresponding position and folding the tapping trace into a corrugated shape as a folding line; sandwiching it in a predetermined corrugated gear and molding it into a corrugated shape, etc. It is not limited.

In order to uniformly fill the granular deodorant 2, it is preferable that the intervals between the valleys of the first filter material 1 processed into a corrugated plate shape are set at equal intervals. The granular deodorizer 2 may be fixed on the first filter material 1 and / or the second filter material 3 with an adhesive or the like, or may not be fixed. When not fixed, ribs or the like can be provided in the valleys so that the granular deodorizer 2 moves greatly and the uniformity is not lost.

本発明では、第一のフィルタ材１と第二のフィルタ材３とで構成される三角形状の開口部４が樹脂５で封鎖される。樹脂５で封鎖されることによって、脱臭フィルタの形状保持が可能となり、また、粒状脱臭剤２の脱落及び空気漏れ（リーク）を防止することができる。また、例えば、図５に示したように、特許文献１（特許第２７９０８５７号公報）に記載されている脱臭フィルタでは、該開口部４における空気漏れのないように、枠材７が接着されているため、脱臭フィルタの形状が実質上、直方体に限られることになり、空気浄化装置の設計の自由度や意匠性向上に制限が生じる課題があったが、三角形状の開口部４が樹脂５で封鎖されている本発明の脱臭フィルタは、第一のフィルタ材１の稜線方向を軸に、任意に曲げることが可能な、柔軟（フレキシブル）なフィルタであり、種々の形状の変形フィルタとなる。その結果、何重にも巻いた巻回状フィルタ；真円筒状、楕円筒状、多角筒状等の筒状フィルタ；コの字形状、Ｓ字形状、Ｕ字形状等の文字形状のフィルタ等；種々の形状のフィルタを製造することができ、搭載される空気浄化装置の自由な設計や意匠性向上に対応することができる。図７〜９は、本発明の脱臭フィルタが任意に変形することが可能であることを説明するための、変形フィルタを示した斜視図であり、樹脂５は省略している。図７は真円筒状の変形フィルタであり、図８はコの字形状の変形フィルタであり、図９はＳ字形状の変形フィルタである。 In the present invention, the triangular opening 4 constituted by the first filter material 1 and the second filter material 3 is sealed with the resin 5. By being sealed with the resin 5, it is possible to maintain the shape of the deodorizing filter, and it is possible to prevent the granular deodorizing agent 2 from dropping and air leakage (leak). Further, for example, as shown in FIG. 5, in the deodorizing filter described in Patent Document 1 (Japanese Patent No. 2790857), the frame material 7 is bonded so that there is no air leakage in the opening 4. Therefore, the shape of the deodorizing filter is substantially limited to a rectangular parallelepiped, and there is a problem that the degree of freedom in design of the air purification device and the improvement in design are limited, but the triangular opening 4 is formed of the resin 5.

第一のフィルタ材１である脱臭機能付き不織布を、プリーツマシンを使用して波高１０ｍｍ、並間隔５ｍｍの波板状に折り曲げ加工し、図４に示すように、波板状の第一のフィルタ材１を平板状に仮固定した状態で、一面側の谷部に、粒状脱臭剤２である円柱状の活性炭ペレット（直径２ｍｍ、高さ４ｍｍ）を均一に充填した。第二のフィルタ材３は活性炭ペレットを充填した面を覆うように、かつ第一のフィルタ材１の山部の頂部６である山部稜線だけに接するように平坦に配置して接着した。接着には、目が粗い非常に高通気なシート状ポリアミド系ホットメルト接着剤を用い、加熱加圧して接着した。 The nonwoven fabric with a deodorizing function which is the first filter material 1 is bent into a corrugated plate shape having a wave height of 10 mm and a parallel interval of 5 mm using a pleat machine, and as shown in FIG. 4, the corrugated first filter In a state where the material 1 was temporarily fixed in a flat plate shape, cylindrical activated carbon pellets (diameter 2 mm, height 4 mm) as the granular deodorizer 2 were uniformly filled in the valleys on one side. The second filter material 3 was flatly disposed and bonded so as to cover the surface filled with the activated carbon pellets and to be in contact with only the peak ridgeline which is the top 6 of the peak of the first filter material 1. For bonding, a sheet-like polyamide-based hot melt adhesive having a rough mesh and a very high air permeability was used and bonded by heating and pressing.
第一のフィルタ材１と第二のフィルタ材３とで構成される三角形状の開口部４は、あらかじめ折り曲げ加工後の平板状に仮固定した状態にある第一のフィルタ材１上の端部において、谷部を埋めるように配しておいたＥＶＡ系ホットメルト樹脂を、第二のフィルタ材３を加熱加圧接着する際に溶融させて、封鎖した。エアフィルタとして実使用上問題のないレベルで該三角形状の開口部４から空気漏れ（リーク）のない実施例１の脱臭フィルタを得た。 The triangular opening 4 constituted by the first filter material 1 and the second filter material 3 is an end portion on the first filter material 1 in a state of being temporarily fixed in a flat shape after bending. The EVA hot melt resin arranged to fill the valleys was melted and sealed when the second filter material 3 was heated and pressure-bonded. The deodorizing filter of Example 1 having no air leakage (leak) was obtained from the triangular opening 4 at a level where there was no problem in practical use as an air filter.
（比較例１）
ホットメルト接着剤を塗布した不織布からなる帯状の枠材７を使用し、三角形状の開口部４を一斉に封鎖した以外は、実施例１と同様にして、比較例１の脱臭フィルタを得た。図５は、比較例１の脱臭フィルタの斜視図であり、第二のフィルタ材３の一部が省略表示されているが、第二のフィルタ材３は粒状脱臭剤２を完全に被覆するように配置される。
(Comparative Example 1)
A deodorizing filter of Comparative Example 1 was obtained in the same manner as in Example 1 except that a belt-like frame material 7 made of a nonwoven fabric coated with a hot-melt adhesive was used and the triangular openings 4 were simultaneously blocked. . FIG. 5 is a perspective view of the deodorizing filter of Comparative Example 1, and a part of the second filter material 3 is omitted, but the second filter material 3 completely covers the granular deodorizing agent 2. Placed in.
（比較例２）
実施例１と同様に波板状に折り曲げ加工した第一のフィルタ材１を、円筒状にして会合部分をＥＶＡ系ホットメルト樹脂で接着、固定した。円筒の内側面の第一のフィルタ材１の山部の頂部６に、接着剤を塗布し、第二のフィルタ材３を、円筒状になるように、第一のフィルタ材１の山部の頂部６に接着し、乾燥して固定した。三角形状の開口部４を封鎖する際に、ホットメルト接着剤を塗布した不織布からなるドーナツ状の枠材８を使用した。最初に片側の三角形の開口部４を一斉にドーナツ状の枠材８で封鎖し、次に反対側の三角形状の開口部４から、実施例１と同様の粒状脱臭剤２を充填した。最後に、粒状脱臭剤２を充填した三角形状の開口部４を、もうひとつのドーナツ状の枠材８で封鎖し、比較例２の脱臭フィルタを得た。図６は比較例２の脱臭フィルタの斜視図である。
(Comparative Example 2)
The first filter material 1 bent into a corrugated plate as in Example 1 was formed into a cylindrical shape, and the association portion was bonded and fixed with an EVA hot melt resin. Adhesive is applied to the top 6 of the crest of the first filter material 1 on the inner side surface of the cylinder, and the second filter material 3 is formed on the crest of the first filter material 1 so as to be cylindrical. Glued to the top 6, dried and fixed. When sealing the triangular opening 4, a donut-shaped frame material 8 made of a nonwoven fabric coated with a hot melt adhesive was used. First, the triangular openings 4 on one side were simultaneously sealed with a donut-shaped frame member 8, and then the same granular deodorizer 2 as in Example 1 was filled from the triangular openings 4 on the opposite side. Finally, the triangular opening 4 filled with the granular deodorizer 2 was sealed with another donut-shaped frame member 8 to obtain a deodorizing filter of Comparative Example 2. 6 is a perspective view of the deodorizing filter of Comparative Example 2. FIG.
実施例１の脱臭フィルタは、枠材を用いていないが、第一フィルタ材１と第二フィルタ材３とで構成される三角形状の開口部４が樹脂５で封鎖されていることで、波板状の第一のフィルタ材１の構造を十分に保持することができ、かつリークを防止できた。また、実施例１の脱臭フィルタは、第一のフィルタ材１の稜線方向を軸に、任意に曲げることが可能で、円筒形状、コの字形状、Ｓ字形状など、種々の形状に柔軟に変形が可能であり、搭載される空気浄化装置の自由な設計や意匠性向上に対応可能であった。また、輸送・保管時の形状を平板形状とすることで、輸送上、保管上の容積を従来同等とし、効率良く輸送や保管を行うことができた。 The deodorizing filter of Example 1 does not use a frame material, but the triangular opening 4 formed by the first filter material 1 and the second filter material 3 is sealed with the resin 5, so The structure of the plate-like first filter material 1 could be sufficiently retained, and leakage could be prevented. Moreover, the deodorizing filter of Example 1 can be arbitrarily bent with the ridge line direction of the first filter material 1 as an axis, and can be flexibly formed into various shapes such as a cylindrical shape, a U shape, and an S shape. Deformation was possible, and it was possible to deal with free design and improved design of the air purification device to be mounted. In addition, by adopting a flat plate shape during transportation and storage, the volume in transportation and storage can be made equivalent to the conventional one, and transportation and storage can be performed efficiently.
比較例１の脱臭フィルタは、帯状の枠材７が用いられている。その結果、脱臭フィルタの形状が変形できない直方体に限られており、空気浄化装置の設計の自由度や意匠性向上に制限が発生した。 The deodorizing filter of Comparative Example 1 uses a strip-shaped frame material 7. As a result, the shape of the deodorizing filter is limited to a rectangular parallelepiped that cannot be deformed, and there has been a restriction on the degree of freedom in design of the air purification device and the improvement in design.
比較例２の脱臭フィルタは円筒形状で、該形状が最適な空気浄化装置などにおいては設計の自由度や意匠性向上に制限を生じさせないと言える。しかしながら、該円筒形状の脱臭フィルタは、円筒形状の中空部分が余剰の空間となり、輸送上や保管上の容積が嵩み、輸送や保管の効率が悪かった。実施例１の脱臭フィルタでは、輸送及び保管時には平板形状として、空気浄化装置に搭載するときには任意の形状をすることができ、輸送や保管の効率が向上した。 The deodorizing filter of Comparative Example 2 has a cylindrical shape, and it can be said that there is no restriction on the degree of freedom in design and the improvement of designability in an air purification device or the like having the optimum shape. However, in the cylindrical deodorizing filter, the hollow portion of the cylindrical shape becomes an excessive space, the volume for transportation and storage increases, and the efficiency of transportation and storage is poor. In the deodorizing filter of Example 1, it was possible to make it into a flat plate shape during transportation and storage, and an arbitrary shape when mounted on the air purification device, thereby improving transportation and storage efficiency.
本発明の脱臭フィルタは、空気清浄機などの空気浄化装置の他、空調機、掃除機、除湿機、乾燥機、加湿機、換気扇、扇風機、熱交換装置等の機械による強制給排気による空気処理装置に装着使用することができる。 The deodorizing filter of the present invention is an air treatment by forced supply / exhaust by a machine such as an air purifier such as an air purifier, an air conditioner, a vacuum cleaner, a dehumidifier, a dryer, a humidifier, a ventilation fan, a fan, a heat exchanger, etc. It can be mounted on the device.
