空気調和機に吸い込まれる空気を清浄するために空気調和機の吸込み口にフィルタを取り付けることが行われている（例えば特許文献１）。 2. Description of the Related Art In order to purify the air sucked into an air conditioner, a filter is attached to the air inlet of the air conditioner (for example, Patent Document 1).

特開２００１－２７４３９号公報JP-A-2001-27439

空気調和機に吸い込まれる空気を清浄するために空気調和機の吸込み口にフィルタを取り付ける場合、空気調和機に吸込まれる空気量は低下することが考えられる。よって、空気調和機の吹出し空気量は低下する虞がある。すなわち、空調対象空間に所望の空気量を吹出すことができない虞がある。また、空気調和機が所望の空気量を吸込むために更なるエネルギーを必要とし、省エネルギー化が実現されない虞が考えられる。 2. Description of the Related Art When a filter is attached to an air inlet of an air conditioner to purify the air drawn into the air conditioner, it is conceivable that the amount of air drawn into the air conditioner decreases. Therefore, there is a possibility that the amount of blown air from the air conditioner will decrease. That is, there is a possibility that a desired amount of air cannot be blown into the air-conditioned space. In addition, there is a possibility that the air conditioner will require more energy to suck in the desired amount of air, and that energy saving will not be achieved.

そこで、本願は、空気調和機へ吸い込まれる空気を清浄しつつ、空気調和機へ吸い込まれる空気量の低下を抑制する技術を開示する。 Therefore, the present application discloses a technique for purifying the air sucked into the air conditioner and suppressing a decrease in the amount of air sucked into the air conditioner.

上記課題を解決するため、本発明では、孔が設けられた空気清浄媒体で空気調和機の吸込み口を覆うこととした。 In order to solve the above problems, in the present invention, the suction port of the air conditioner is covered with an air cleaning medium provided with holes.

詳細には、本発明は、空気調和機の外表面の吸込み部分を覆う空気清浄媒体であって、通気性素材を含み、空気中の不純物を捕捉する通気部と、吸込み部分に通気部を固定する固定部と、を備え、通気部は、吸込み部分へ吸込まれる空気が通過する孔を有する、空気清浄媒体である。 More specifically, the present invention provides an air purification medium covering the suction portion of the outer surface of an air conditioner, which includes a ventilation section that includes a breathable material and traps impurities in the air, and the ventilation section is fixed to the suction section. and a fixed part, wherein the vent part is an air purification medium having holes through which air is drawn into the suction part.

このような空気清浄媒体は、空気調和機の吸込み部分へ吸込まれる空気に含まれる不純物を捕捉する。よって、空気調和機の吸込み部分へ吸込まれる空気は清浄される。また、通気部に孔が設けられているため、空気調和機に吸い込まれる空気量の低下は抑制される。よって、空調対象空間に所望の空気量を吹出すことができる。また、空気調和機が吸込み空気を吸込むためのエネルギーは節減される。 Such air cleaning media trap impurities contained in the air drawn into the suction section of the air conditioner. Therefore, the air sucked into the suction portion of the air conditioner is purified. In addition, since the ventilation part is provided with holes, a decrease in the amount of air sucked into the air conditioner is suppressed. Therefore, a desired amount of air can be blown into the air-conditioned space. In addition, energy is saved for the air conditioner to suck the intake air.

また、空気清浄媒体は、空気中に存在する物質と化学反応し、ラジカルを生成させる物質を含み、通気性素材にコーティングされるラジカル生成部をさらに備えてもよい。 In addition, the air cleaning medium may further include a radical generator that contains a substance that chemically reacts with substances present in the air to generate radicals and that is coated on the air-permeable material.

このような空気清浄媒体であれば、ラジカル生成部が通気性素材にコーティングされているため、通気性素材を通過する空気、あるいは通気部に設けられた孔を通過し、空気調和機の吸込み部分へ吸込まれる空気に含まれる病原菌やウイルスといった不純物は無害化される。すなわち、このような空気清浄媒体であれば、空気調和機へ吸い込まれる空気は清浄されつつ、空気調和機へ吸い込まれる空気量の低下は抑制される。 With such an air purification medium, since the radical generating part is coated with the air-permeable material, air passing through the air-permeable material or passing through the holes provided in the air-permeable part will reach the suction part of the air conditioner. Impurities such as pathogenic bacteria and viruses contained in the air drawn into the air are rendered harmless. That is, with such an air purifying medium, the air sucked into the air conditioner is purified, and the decrease in the amount of air sucked into the air conditioner is suppressed.

また、空気清浄媒体は、通気性素材の密度よりも低く、気散性の物質を含む第２の通気性素材を更に備え、孔は、第２の通気性素材により覆われてもよい。 Also, the air purification medium may further comprise a second breathable material having a lower density than the breathable material and containing a diffusing material, the pores being covered by the second breathable material.

このような空気清浄媒体であれば、孔は覆われるため、孔を通過する空気中に存在する不純物は捕捉される。また、孔を覆う第２の通気性素材は、通気性素材よりも密度が低いため、通気性の低下は抑制される。すなわち、空気調和機へ吸い込まれる空気は清浄されつつ、空気調和機へ吸い込まれる空気量の低下は抑制される。 With such an air cleaning medium, the pores are covered, so impurities present in the air passing through the pores are captured. In addition, since the second breathable material that covers the holes has a lower density than the breathable material, deterioration in breathability is suppressed. That is, the air sucked into the air conditioner is cleaned, and the decrease in the amount of air sucked into the air conditioner is suppressed.

また、第２の通気性素材に含まれる気散性の物質は、吸込み部分から空気調和機へ吸込まれ、空調対象空間へ吹き出される。よって、気散性の物質が芳香性又は消臭性を有する物質の場合、吹出し空気は、不純物が無害化され、芳香性又は消臭性を有する空気である。つまり空調対象空間は、衛生的となり、空調対象空間にいる人間の心理、精神に良い影響が及ぼされる。 Also, the diffuse substance contained in the second air-permeable material is sucked into the air conditioner through the suction portion and blown out into the air-conditioned space. Therefore, when the dispersive substance is a substance having fragrant or deodorant properties, the blown air is air in which impurities are detoxified and which has fragrant or deodorant properties. In other words, the air-conditioned space becomes hygienic, and the psychology and spirit of people in the air-conditioned space are favorably affected.

また、気散性の物質は、芳香性又は消臭性のうち、少なくとも１つの性質を有してもよい。 Also, the diffusing material may have at least one of the properties of being fragrant or deodorant.

気散性の物質は、吸込み部分から空気調和機へ吸込まれ、空調対象空間へ吹き出される。よって、吹出し空気は、不純物が無害化され、芳香性又は消臭性のうち、少なくとも１つの性質を有する空気である。つまり空調対象空間は、衛生的となり、空調対象空間にいる人間の心理、精神に良い影響が及ぼされる。 The diffuse substance is sucked into the air conditioner from the suction portion and blown out to the air-conditioned space. Therefore, the blown air is air in which impurities are detoxified and which has at least one property of aromaticity and deodorization. In other words, the air-conditioned space becomes hygienic, and the psychology and spirit of people in the air-conditioned space are favorably affected.

また、通気性素材の開孔率は、３０％以上であってもよい。このような空気清浄媒体であれば、通気性の低下は抑制される。よって、空気調和機へ吸い込まれる空気は清浄されつつ、空気調和機へ吸い込まれる空気量の低下は抑制される。 In addition, the porosity of the air-permeable material may be 30% or more. With such an air cleaning medium, deterioration in air permeability is suppressed. Therefore, while the air sucked into the air conditioner is purified, the decrease in the amount of air sucked into the air conditioner is suppressed.

また、空気調和機は、外表面の中央部分に設けられる吸込み部分と、吸込み部分の周囲に設けられる吹出し部分と、を有し、孔は、通気部の中央部分に設けられてもよい。 Further, the air conditioner may have a suction portion provided in the central portion of the outer surface and a blowout portion provided around the suction portion, and the hole may be provided in the central portion of the ventilation portion.

このような空気清浄媒体であれば、吹出し部分と孔とは離れている。よって、吹出し部分から吹き出された空気が空調対象空間へ拡散せず、孔を介して再度空気調和機へ吸込まれることは抑制される。すなわち、空調対象空間へ清浄された空気が拡散される。 With such an air purification medium, the blowout portion and the holes are separated. Therefore, the air blown out from the blowing portion does not diffuse into the air-conditioned space, and is prevented from being sucked into the air conditioner again through the holes. That is, the cleaned air is diffused into the air-conditioned space.

上記の空気清浄媒体は、空気調和機へ吸い込まれる空気を清浄しつつ、空気調和機へ吸い込まれる空気量の低下を抑制する。 The above air cleaning medium purifies the air sucked into the air conditioner and suppresses a decrease in the amount of air sucked into the air conditioner.

以下、本発明の実施形態について説明する。以下に示す実施形態は、本発明の一形態であり、本発明の技術的範囲を下記の実施形態に限定するものではない。 Embodiments of the present invention will be described below. The embodiment shown below is one form of the present invention, and the technical scope of the present invention is not limited to the following embodiment.

図１は、本発明に係る空気清浄媒体の概要図である。空気清浄媒体１は、通気性素材である不織布２を備える。不織布２は、例えばポリエステルから形成される。また、不織布２の外形の一辺の長さは、例えば５７ｃｍである。また、不織布２には、例えばラジカル生成部の一態様である空気触媒がコーティングされている。空気触媒は、例えばニチリンケミカル社製品のセルフィーユ（登録商標）が挙げられる。セルフィーユは、http://www.nichirin-chemical.co.jp/に記載されているように、空気中に存在する水や酸素と化学反応し、ラジカルを生成する。また、不織布２の色は、不純物が付着して蓄積した際に、不純物の付着を認識できるように、不純物の色とは異なる色であることが望ましい。また、不織布２には、例えばヒノキの幹から抽出される天然抗菌成分であるヒノキチオールが含まれている。 FIG. 1 is a schematic diagram of an air cleaning medium according to the present invention. The air purification medium 1 includes a nonwoven fabric 2 that is a breathable material. The nonwoven fabric 2 is made of polyester, for example. Moreover, the length of one side of the outer shape of the nonwoven fabric 2 is, for example, 57 cm. Further, the nonwoven fabric 2 is coated with an air catalyst, which is one aspect of the radical generator, for example. Air catalysts include, for example, Serfeuille (registered trademark) manufactured by Nichirin Chemical Co., Ltd. As described at http://www.nichirin-chemical.co.jp/, Cerfeuille chemically reacts with water and oxygen present in the air to generate radicals. Moreover, the color of the nonwoven fabric 2 is desirably a color different from the color of impurities so that when impurities adhere and accumulate, the adherence of impurities can be recognized. In addition, the nonwoven fabric 2 contains hinokitiol, which is a natural antibacterial component extracted from, for example, the trunk of the Japanese cypress.

また、不織布２は、空気調和機７へ取り付けられる側の取付け面３に、空気調和機７と粘着する粘着部分４を備える。粘着部分４は、取付け面３の外周に沿って設けられる。また、粘着部分４は、取付け面３の外周に沿った部分以外にも、取付け面３の面内に設けられる。ここで、粘着部分４は、本発明の「固定部」の一例である。 Moreover, the nonwoven fabric 2 has an adhesive portion 4 that adheres to the air conditioner 7 on the attachment surface 3 on the side attached to the air conditioner 7 . The adhesive portion 4 is provided along the outer circumference of the mounting surface 3 . Further, the adhesive portion 4 is provided within the surface of the mounting surface 3 in addition to the portion along the outer circumference of the mounting surface 3 . Here, the adhesive part 4 is an example of the "fixing part" of the present invention.

不織布２の取付け面３とは反対側の、空気が吸込まれる吸込み面５には、不純物が付着しない防汚部分６を備える。図２は、吸込み面５の概要図を示している。防汚部分６は、例えば複数の直線が交差した模様である。 A suction surface 5 for sucking air on the side opposite to the mounting surface 3 of the nonwoven fabric 2 is provided with an antifouling portion 6 to which impurities do not adhere. FIG. 2 shows a schematic diagram of the suction surface 5 . The antifouling portion 6 is, for example, a pattern in which a plurality of straight lines intersect.

また、不織布２は、孔２０を備える。孔２０の開孔面積の総和は、例えば１００ｃｍ２である。すなわち、不織布２の開孔率は、約３０％である。また、孔２０は、不織布２の中央部分に４つ設けられる。孔２０の形状は何でもよい。また、孔２０の個数は何個でもよい。また、孔２０が設けられる位置は、どこでもよく、不織布２の端部分に設けられてもよい。また、不織布の大きさや孔の寸法は、上記の数値に限定されない。The nonwoven fabric 2 also has holes 20 . The total open area of the holes 20 is, for example, 100 cm 2 . That is, the nonwoven fabric 2 has a porosity of about 30%. Four holes 20 are provided in the central portion of the nonwoven fabric 2 . The hole 20 may have any shape. Also, any number of holes 20 may be provided. Moreover, the position where the hole 20 is provided may be anywhere, and may be provided at the end portion of the nonwoven fabric 2 . Also, the size of the nonwoven fabric and the size of the pores are not limited to the above values.

図３は、空気清浄媒体１を、例えば天井埋め込み型の空気調和機７の吸込み口８に取付けた際の概要図である。空気調和機７は、中央部分に吸込み口８を備える。また、空気調和機７は、吸込み口８の周囲に吹出し口１０を備える。ここで、吸込み口８は、本発明の「吸込み部分」の一例である。また、吹出し口１０は、本発明の「吹出し部分」の一例である。空気清浄媒体１は、吸込み口８を覆うように空気調和機７の外表面に取付けられる。この際、空気清浄媒体１の取付け面３の外周に沿って設けられた粘着部分４は、吸込み口８の外周に粘着される。ここで、空気清浄媒体１は、吸込み口８の大きさに合わせて適当な大きさに切られてもよい。 FIG. 3 is a schematic diagram when the air cleaning medium 1 is attached to the suction port 8 of a ceiling-embedded air conditioner 7, for example. The air conditioner 7 has a suction port 8 in its central portion. The air conditioner 7 also has an outlet 10 around the suction port 8 . Here, the suction port 8 is an example of the "suction portion" of the present invention. Also, the blowout port 10 is an example of the "blowing part" of the present invention. The air cleaning medium 1 is attached to the outer surface of the air conditioner 7 so as to cover the suction port 8 . At this time, the adhesive portion 4 provided along the outer circumference of the mounting surface 3 of the air cleaning medium 1 is adhered to the outer circumference of the suction port 8 . Here, the air purification medium 1 may be cut into a suitable size according to the size of the suction port 8.

図４は、空気調和機７の電源を入れた際の気流の流れを示した図である。空気調和機７の電源を入れると、空調対象空間９から空気調和機７の吸込み口８に貼り付けられた空気清浄媒体１の吸込み面５へ向かって、気流が発生し、空気調和機７の内部へ空気が吸込まれる。ここで、不織布２の中央部分には、孔２０が設けられているため、空気調和機７の内部への通気性の低下は抑制される。 FIG. 4 is a diagram showing the flow of air when the power of the air conditioner 7 is turned on. When the power of the air conditioner 7 is turned on, an airflow is generated from the air-conditioned space 9 toward the suction surface 5 of the air cleaning medium 1 attached to the suction port 8 of the air conditioner 7. Air is sucked inside. Here, since the hole 20 is provided in the central portion of the nonwoven fabric 2, the decrease in air permeability to the inside of the air conditioner 7 is suppressed.

また、空気調和機７へ吸込まれる空気には、例えば、埃、塵、煙草の脂、花粉、細菌、ウイルス、ハウスダストといった不純物が含まれる。これら不純物のうち、埃、塵、花粉、煙草の脂、ハウスダストといった比較的粒径が大きい不純物は、空気清浄媒体１の不織布２によって捕捉される。 Also, the air sucked into the air conditioner 7 contains impurities such as dust, dust, tobacco grease, pollen, bacteria, viruses, and house dust. Among these impurities, impurities having relatively large particle sizes such as dust, dust, pollen, tobacco grease, and house dust are captured by the nonwoven fabric 2 of the air cleaning medium 1 .

しかしながら、細菌やウイルスのように粒径が小さい不純物は、不織布２によって捕捉されず、不織布２内の隙間を通過し、空気調和機７の中へ吸込まれる場合がある。また、細菌やウイルスのように粒径が小さい不純物は、孔２０を通過して空気調和機７の中へ吸い込まれる場合がある。本実施形態の空気清浄媒体１であれば、上記のような細菌やウイルスが不織布２によって捕捉されない場合においても、細菌やウイルスは、不織布２にコーティングされた空気触媒によって生成されるラジカルによって酸化され、その機能は失われる。図５は、空気清浄媒体１によって、空気調和機７へ吸込まれる空気が清浄される様子を説明した断面図である。 However, impurities with small particle sizes such as bacteria and viruses may pass through gaps in the nonwoven fabric 2 and be sucked into the air conditioner 7 without being captured by the nonwoven fabric 2 . Also, impurities with small particle sizes such as bacteria and viruses may pass through the holes 20 and be sucked into the air conditioner 7 . With the air cleaning medium 1 of the present embodiment, even if the nonwoven fabric 2 does not capture the above bacteria and viruses, the bacteria and viruses are oxidized by radicals generated by the air catalyst coated on the nonwoven fabric 2. , its functionality is lost. FIG. 5 is a cross-sectional view illustrating how the air sucked into the air conditioner 7 is cleaned by the air cleaning medium 1. As shown in FIG.

＜作用・効果＞
上記のような空気清浄媒体１であれば、不織布２に孔２０が設けられている。また、不織布２の開孔率は約３０％である。よって、空気調和機７へ吸込まれる空気量の低下は抑制される。よって、空調対象空間に所望の空気量を吹出すことができる。また、空気調和機７が吸込み空気を吸込むためのエネルギーは節減される。<Action/effect>
In the air cleaning medium 1 as described above, the nonwoven fabric 2 is provided with the holes 20 . In addition, the nonwoven fabric 2 has a porosity of about 30%. Therefore, a decrease in the amount of air sucked into the air conditioner 7 is suppressed. Therefore, a desired amount of air can be blown into the air-conditioned space. Also, the energy required for the air conditioner 7 to suck in the air is saved.

また、空気触媒が不織布２にコーティングされているため、不織布２を通過する、あるいは孔２０を通過する空気中に含まれる病原菌やウイルスといった不純物は無害化される。また、不織布２によって、病原菌やウイルスよりも大きい不純物は捕捉される。すなわち、このような空気清浄媒体１であれば、空気調和機７へ吸い込まれる空気は清浄されるとともに、空気調和機７へ吸込まれる空気量の低下は抑制される。 In addition, since the air catalyst is coated on the nonwoven fabric 2, impurities such as pathogens and viruses contained in the air passing through the nonwoven fabric 2 or passing through the holes 20 are rendered harmless. In addition, the nonwoven fabric 2 captures impurities larger than pathogenic bacteria and viruses. That is, with such an air cleaning medium 1, the air sucked into the air conditioner 7 is cleaned, and the decrease in the amount of air sucked into the air conditioner 7 is suppressed.

また、このような空気清浄媒体であれば、吹出し口１０と孔２０とは離れている。よって、吹出し口１０から吹き出された空気が空調対象空間９へ拡散せず、孔２０を介して再度空気調和機７へ吸込まれることは抑制される。よって、清浄された空気は、空調対象空間へ拡散される。 Moreover, with such an air cleaning medium, the outlet 10 and the hole 20 are separated from each other. Therefore, the air blown out from the outlet 10 does not diffuse into the air-conditioned space 9 and is prevented from being sucked into the air conditioner 7 again through the holes 20 . Therefore, the cleaned air is diffused into the air-conditioned space.

また、上記のような空気清浄媒体１であれば、空気調和機７の内部のフィンに衛生機能を有する物質を加工するのではなく、空気清浄媒体１を空気調和機７の吸込み口８へ貼り付けるだけで、空調対象空間９へ衛生的な空気を供給することができる。よって、衛生機能を有する物質を空気調和機７へ加工する費用を低減することができる。 In the case of the air purifying medium 1 as described above, instead of processing the fins inside the air conditioner 7 with a substance having a sanitary function, the air purifying medium 1 is attached to the suction port 8 of the air conditioner 7. Hygienic air can be supplied to the air-conditioned space 9 only by attaching it. Therefore, it is possible to reduce the cost of processing a substance having sanitary functions into the air conditioner 7 .

また、上記のような空気清浄媒体１であれば、空気調和機７を開け、空気調和機７の内部を定期的に清掃する手間を省くことができる。また、空気清浄媒体１は、空気調和機７の外表面に粘着されることによって取り付けられる。よって、空気清浄媒体１は、空気調和機７への設置や交換の手間を要さずに済む。 Further, with the air cleaning medium 1 as described above, the trouble of opening the air conditioner 7 and periodically cleaning the inside of the air conditioner 7 can be saved. Also, the air purification medium 1 is attached by being adhered to the outer surface of the air conditioner 7 . Therefore, the air purification medium 1 does not require time and effort to install or replace it in the air conditioner 7 .

また、不織布２は、例えば煙草、汗、し尿の成分であるアンモニア、卵等が腐った際に発生する硫化水素、玉葱等が腐った際に発生するメチルメルカプタン、建築材料の合板や壁紙、床、家具の接着剤等に用いられるホルムアルデヒド、といった臭気性の不純物も捕捉する、あるいは、その機能を失わせることができてもよい。このような空気清浄媒体１であれば、空気調和機７の内部及び空調対象空間９の消臭も実現される。 In addition, the nonwoven fabric 2 includes, for example, ammonia, which is a component of cigarettes, sweat, and night soil, hydrogen sulfide generated when eggs and the like rot, methyl mercaptan generated when onions and the like rot, plywood and wallpaper used as building materials, and floors. It may also be able to trap or disable odorous impurities such as formaldehyde, which is used in furniture adhesives and the like. With such an air purification medium 1, the inside of the air conditioner 7 and the air-conditioned space 9 can be deodorized.

また、不織布２には、天然由来の成分である、例えばヒノキチオールがコーティングされている。ヒノキチオールは、例えば殺菌機能や抗菌機能といった衛生機能を有する。よって、このような空気清浄媒体１であれば、空気調和機７の吸込み口８へ空気清浄媒体１を取り付ける際、空気清浄媒体１を指でつまむ必要があるが、この際に手の皮膚細胞が壊される虞は低い。 In addition, the nonwoven fabric 2 is coated with, for example, hinokitiol, which is a naturally derived component. Hinokitiol has sanitary functions such as bactericidal and antibacterial functions. Therefore, with such an air purifying medium 1, when attaching the air purifying medium 1 to the suction port 8 of the air conditioner 7, it is necessary to pinch the air purifying medium 1 with fingers. is less likely to be destroyed.

また、上記のように、空調対象空間９の空気を清浄していると、不織布２には、捕捉された不純物が溜まっていき、空気清浄媒体１の吸込み面５の外観は変色する。図６は、空気清浄媒体１の吸込み面５が不純物の蓄積により変色した例を示している。吸込み面５が不純物の蓄積により変色した場合、吸込み面５の不純物が捕捉された部分と、不純物が付着しない防汚部分６とは、明らかに外観が異なることとなる。 Further, as described above, when the air in the air-conditioned space 9 is cleaned, trapped impurities accumulate in the nonwoven fabric 2, and the appearance of the suction surface 5 of the air purification medium 1 changes color. FIG. 6 shows an example in which the suction surface 5 of the air cleaning medium 1 is discolored due to accumulation of impurities. When the suction surface 5 is discolored due to the accumulation of impurities, the appearance of the portion of the suction surface 5 where the impurities are trapped and the antifouling portion 6 where no impurities adhere will clearly differ.

上記のような場合には、不織布２に不純物が蓄積され、通気性が低下しているため、空気調和機７へ吸込まれる空気量は大幅に低下する。よって、空気調和機７の吹出し口１０から吹出される空気量も大幅に低下する。また、空気調和機７から吹出される空気量の低下を防止するために、吹出し動力を上げなければならず、空気調和機７の運転に要する費用が嵩む。 In the above case, impurities are accumulated in the nonwoven fabric 2 and the air permeability is lowered, so the amount of air sucked into the air conditioner 7 is greatly reduced. Therefore, the amount of air blown out from the outlet 10 of the air conditioner 7 is also greatly reduced. In addition, in order to prevent the amount of air blown from the air conditioner 7 from decreasing, the blowing power must be increased, which increases the cost required to operate the air conditioner 7 .

また、このように不純物が蓄積し、吸込み面５と防汚部分６との外観が異なる程に空気の清浄を行うと、不織布２にコーティングされた空気触媒やヒノキチオールの量は減っており、空気触媒やヒノキチオールの効果が低減している。よって、図６のように吸込み面５の外観が、防汚部分６の外観と比較して明らかに異なる場合には、空気清浄媒体１を交換する必要がある。換言すれば、上記のような防汚部分６を備える空気清浄媒体１であれば、交換の頃合を容易に把握することができる。 In addition, when impurities are accumulated in this way and the air is cleaned to such an extent that the appearance of the suction surface 5 and the antifouling portion 6 is different, the amount of the air catalyst and hinokitiol coated on the nonwoven fabric 2 is reduced, and the amount of air is reduced. The effect of catalyst and hinokitiol is reduced. Therefore, when the appearance of the suction surface 5 is clearly different from that of the antifouling portion 6 as shown in FIG. 6, the air cleaning medium 1 needs to be replaced. In other words, with the air purification medium 1 having the antifouling portion 6 as described above, it is possible to easily grasp the timing of replacement.

また、空気清浄媒体１は、空気調和機７に吸込まれる空気の気流によって、自然に空気調和機７の筐体方向へ張り付く。よって、空気調和機７が運転している際に、空気調和機７から空気清浄媒体１が剥がれ落ちる可能性は低い。 Also, the air cleaning medium 1 naturally sticks toward the housing of the air conditioner 7 due to the flow of air sucked into the air conditioner 7 . Therefore, the air cleaning medium 1 is less likely to come off from the air conditioner 7 while the air conditioner 7 is in operation.

また、不織布２には、例えば人間をリラックスさせる効果や集中力を増す効果を有する香料が含まれていてもよい。このような空気清浄媒体１であれば、空気調和機７の吹出し口１０から上記の香料が混ざった空気が吹出され、空調対象空間９にいる人間が上記の香料の混ざった空気を吸込む。よって、香料の混ざった空気を吸込んだ人間の心理や精神に良い影響を与えることができる。 In addition, the nonwoven fabric 2 may contain a perfume having, for example, a relaxing effect or an effect of increasing concentration. With such an air cleaning medium 1, the air mixed with the perfume is blown out from the outlet 10 of the air conditioner 7, and a person in the air-conditioned space 9 inhales the air mixed with the perfume. Therefore, it can have a positive effect on the psychology and spirit of a person who inhales air mixed with fragrance.

＜変形例＞
図７は、空気清浄媒体１Ａの概要の一例を示している。空気清浄媒体１Ａは、孔２０を覆うように不織布２１を備える。ただし、不織布２１の密度は、不織布２の密度よりも低い。ここで、不織布２１は、本発明の「第２の通気性素材」の一例である。<Modification>
FIG. 7 shows an example of an overview of the air cleaning medium 1A. The air cleaning medium 1A includes a nonwoven fabric 21 so as to cover the holes 20. - 特許庁However, the density of the nonwoven fabric 21 is lower than the density of the nonwoven fabric 2 . Here, the nonwoven fabric 21 is an example of the "second breathable material" of the present invention.

また、不織布２１には、例えばトドマツの粉体２２がコーティングされる。ここで、トドマツの粉体２２は、本発明の「気散性の物質」の一例である。トドマツの粉体２２は、例えばhttp://www.kaoriken.com/business/feature.html等に記載されているように、粉体中に含まれるβ－フェランドレンが消臭性及び芳香性を有する。また、トドマツの粉体２２は、粉体中に含まれる物質が大気汚染物質の無害化などの効果を有する。 Further, the nonwoven fabric 21 is coated with powder 22 of Todomatsu, for example. Here, the Todomatsu powder 22 is an example of the "dispersive substance" of the present invention. The Sakhalin fir powder 22 has deodorant and aromatic properties as described in http://www.kaoriken.com/business/feature.html, for example. have. In addition, the Sakhalin fir powder 22 has an effect that the substance contained in the powder renders air pollutants harmless.

上記のような空気清浄媒体１Ａは、孔２０が不織布２１によって覆われるため、不織布２１を通過する空気に含まれる不純物は捕捉される。また、病原菌やウイルスといった不純物が不織布２１を通過する場合、不織布２にコーティングされる空気触媒によって病原菌やウイルスといった不純物は無害化される。すなわち、空気調和機７へ吸い込まれる空気は清浄される。 In the air cleaning medium 1A as described above, since the holes 20 are covered with the nonwoven fabric 21, impurities contained in the air passing through the nonwoven fabric 21 are captured. Moreover, when impurities such as pathogenic bacteria and viruses pass through the nonwoven fabric 21, the air catalyst coated on the nonwoven fabric 2 renders the impurities such as pathogenic bacteria and viruses harmless. That is, the air sucked into the air conditioner 7 is purified.

また、孔２０を覆う不織布２１の密度は、不織布２の密度よりも密度が低い。よって、空気清浄媒体１Ａの通気性の低下は抑制される。すなわち、このような空気清浄媒体１Ａであれば、空気調和機７へ吸い込まれる空気は清浄されるとともに、空気調和機７へ吸込まれる空気量の低下は抑制される。 Moreover, the density of the nonwoven fabric 21 covering the holes 20 is lower than the density of the nonwoven fabric 2 . Therefore, deterioration of the air permeability of the air cleaning medium 1A is suppressed. That is, with such an air cleaning medium 1A, the air sucked into the air conditioner 7 is purified, and the decrease in the amount of air sucked into the air conditioner 7 is suppressed.

また、トドマツの粉体２２は、消臭芳香性を有する。よって、吸込み口８から空気調和機７へ吸込まれ、空調対象空間へ吹出される吹出し空気は、清浄されていることに加えて芳香消臭性を有する。つまり空調対象空間は、衛生的であり、空調対象空間にいる人間の心理や精神に良い影響を与えることができる。 Moreover, the Sakhalin fir powder 22 has deodorizing and aromatic properties. Therefore, the blown air that is sucked into the air conditioner 7 from the suction port 8 and blown out to the air-conditioned space is cleaned and has a deodorizing effect. In other words, the air-conditioned space is hygienic and can have a positive effect on the psychology and spirit of people in the air-conditioned space.

また、空気清浄媒体１の形状はひし形でも正方形でも台形でもなんでもよい。また、空気触媒は、不織布２の全面にわたってコーティングされていても、一部分にのみ加えられていてもよい。また、空気触媒は不織布２にコーティングされていなくてもよい。 Moreover, the shape of the air cleaning medium 1 may be any shape such as rhombus, square, or trapezoid. Moreover, the air catalyst may be coated over the entire surface of the nonwoven fabric 2 or may be added to only a portion thereof. Moreover, the nonwoven fabric 2 may not be coated with the air catalyst.

また、上記の実施形態では、空気触媒が不織布２にコーティングされる空気清浄媒体の一例を示したが、不織布２にコーティングされる物質は空気触媒に限られない。不織布２にコーティングされる物質は、例えば、トドマツ、ミネルパ（登録商標）といった物質を含んでもよい。 Further, in the above-described embodiment, an example of an air purification medium in which the nonwoven fabric 2 is coated with an air catalyst is shown, but the material with which the nonwoven fabric 2 is coated is not limited to the air catalyst. The substance with which the nonwoven fabric 2 is coated may include, for example, Sakhalin fir or Minerpa (registered trademark).

また、ヒノキチオールや香料は、不織布２の全面にわたって加えられていても、一部分に加えられていても、加えられていなくてもよい。 In addition, hinokitiol and perfume may be added to the entire surface of the nonwoven fabric 2, may be added to a portion thereof, or may not be added.

また、不織布２の素材は、何でもよく、例えば紙を含んでもよい。また、例えば市販のペットボトル容器から得られるポリエステルを不織布２の素材に再利用してもよい。また、不織布２の代わりに、埃や塵程度の大きさの不純物を捕捉し、空気触媒をコーティングできる通気性の材料を用いてもよい。また、空気調和機７の形状は何でもよい。また、空気調和機７の種類は、天井埋め込み型に限らず、天井吊り下げ型、壁掛け型、床置き型などであってもよい。 Moreover, the material of the nonwoven fabric 2 may be anything, and may include paper, for example. Further, for example, polyester obtained from a commercially available PET bottle container may be reused as the material of the nonwoven fabric 2 . Also, instead of the non-woven fabric 2, an air-permeable material that can capture dust and impurities of a size similar to dust and that can be coated with an air catalyst may be used. Moreover, the air conditioner 7 may have any shape. Further, the type of the air conditioner 7 is not limited to the ceiling-embedded type, and may be a ceiling-suspended type, a wall-mounted type, a floor-mounted type, or the like.

また、粘着部分４は、空気清浄媒体１の清浄機能が著しく低下せず、空気調和機７へ貼り付けることができる程度に取付け面３に設けられていてもよい。また、空気清浄媒体１は粘着部分４を備えず、空気調和機７へ固定される代替手段を備えてもよい。代替手段とは、例えば、空気調和機７にピンが設けられている場合、当該ピンと嵌合する孔などでもよい。また、防汚部分６は、複数の直線が交差した模様に限らず、空気清浄媒体１の使用後に、不純物を捕捉した部分と防汚部分６とが形成する模様が外部から視認でき、交換の頃合を容易に把握できるような形態であればよい。 Also, the adhesive portion 4 may be provided on the attachment surface 3 to such an extent that the air cleaning medium 1 can be attached to the air conditioner 7 without significantly deteriorating the cleaning function thereof. Alternatively, the air cleaning medium 1 may not have the adhesive portion 4 and may have an alternative means of being fixed to the air conditioner 7 . For example, when the air conditioner 7 is provided with a pin, the alternative means may be a hole to be fitted with the pin. In addition, the antifouling portion 6 is not limited to the pattern in which a plurality of straight lines intersect, and after the air purification medium 1 is used, the pattern formed by the part that traps impurities and the antifouling portion 6 can be visually recognized from the outside. Any form is acceptable as long as the timing can be easily grasped.
