しかしながら、特許文献1のエレクトレットフィルタをエアフィルタとして用いると、油分の付着により帯電が低下し、捕集効果が下がるといった問題点がある。 However, when the electret filter of Patent Document 1 is used as an air filter, there is a problem that the charge is lowered due to the adhesion of oil and the collection effect is lowered.

そこで、本考案は、捕集効果が持続するエアフィルタの提供を目的とする。 Therefore, an object of the present invention is to provide an air filter having a long-lasting collection effect.

本考案は、気流の中に設けられるエアフィルタであって、気流の下流側に配置される不織布製の帯電フィルタと、気流の上流側に配置され、前記帯電フィルタに対して厚み方向で重ねて接合される不織布製の非帯電フィルタと、を備えることを特徴とする。 The present invention is an air filter provided in the airflow, which is a non-woven fabric charging filter arranged on the downstream side of the airflow and is arranged on the upstream side of the airflow and is overlapped with the charging filter in the thickness direction. It is characterized by comprising a non-woven fabric non-charged filter to be joined.

上記構成のエアフィルタでは、上流側の非帯電フィルタによって油分が捕集されるため、下流側の帯電フィルタへの油分の付着が抑制される。よって、帯電フィルタの捕集性能を維持でき、エアフィルタとしての捕集性能を持続させることができる。 In the air filter having the above configuration, the oil content is collected by the non-charged filter on the upstream side, so that the adhesion of the oil content to the charged filter on the downstream side is suppressed.

本考案は、前記帯電フィルタの目付は、前記非帯電フィルタの目付より小さい構成を採用することができる。 In the present invention, the basis weight of the charging filter can be smaller than that of the non-charging filter.

上記構成のエアフィルタでは、気流の上流側の非帯電フィルタで先に大きいもの(物質)を捕集し、下流側の帯電フィルタで残りの小さいものを捕集することで、高い捕集性能が発揮される。 In the air filter having the above configuration, the non-charged filter on the upstream side of the airflow collects the large ones (substances) first, and the charged filter on the downstream side collects the remaining small ones, thereby achieving high collection performance. It is demonstrated.

本考案は、前記帯電フィルタの厚みは、前記非帯電フィルタの厚みより薄い構成を採用することができる。 In the present invention, the thickness of the charging filter can be thinner than the thickness of the non-charging filter.

上記構成のエアフィルタでは、目付の小さい帯電フィルタを、目付の大きい非帯電フィルタよりも薄い厚みとすることで、気流の圧力損失を制御することができる。 In the air filter having the above configuration, the pressure loss of the airflow can be controlled by making the charge filter having a small basis weight thinner than the non-charged filter having a large basis weight.

本考案では、前記帯電フィルタと前記非帯電フィルタとは、厚み方向で重なる領域内に形成される接合部を介して接合されており、該接合部は、前記重なる領域内に形成された構成を採用することができる。 In the present invention, the charging filter and the non-charging filter are joined via a joining portion formed in the overlapping region in the thickness direction, and the joining portion has a configuration formed in the overlapping region. Can be adopted.

上記構成のエアフィルタでは、捕集性能を確保しつつ両フィルタを強固に接合することができる。 With the air filter having the above configuration, both filters can be firmly joined while ensuring the collection performance.

本考案では、前記接合部は、前記帯電フィルタの繊維と前記非帯電フィルタの繊維とが、互いに絡み合う、又は、溶着して形成されている構成を採用することができる。 In the present invention, the joint can adopt a structure in which the fibers of the charging filter and the fibers of the non-charging filter are entangled with each other or welded together.

上記構成のエアフィルタでは、繊維どうしが絡み合う、又は、溶着されることで、帯電フィルタの繊維と非帯電フィルタとが、しっかりと接合される。 In the air filter having the above configuration, the fibers of the charged filter and the non-charged filter are firmly joined by entanglement or welding of the fibers.

本考案では、前記非帯電フィルタの繊維は、少なくとも酸化チタンとジメチル・フェニル・スルファルドを含むコーティング剤でコーティングされている構成を採用することができる。 In the present invention, the fiber of the non-charged filter can adopt a structure coated with a coating agent containing at least titanium oxide and dimethyl phenyl sulfard.

上記構成のエアフィルタでは、気流中の有害汚染物質を軽減し、埃や黴などの汚れを捕集し、ウィルスや菌を捕集し、消毒することができる。 The air filter having the above configuration can reduce harmful pollutants in the air flow, collect dirt such as dust and mold, collect viruses and bacteria, and disinfect them.

本考案では、前記帯電フィルタは、厚み方向の表面が正極、裏面が負極となる高配向分極構造を有する。 In the present invention, the charging filter has a highly oriented polarization structure in which the front surface in the thickness direction is a positive electrode and the back surface is a negative electrode.

以下、本考案の一実施形態に係るエアフィルタを説明する。まず、第一の実施形態を図1、図2を参照して説明する。図1に示すように、本考案のエアフィルタ1は、エアコンデイショナ2の室内機における気流3の中に配置されるものであり、帯電フィルタ4と非帯電フィルタ5とが厚み方向で重ねられた構成である。 Hereinafter, the air filter according to the embodiment of the present invention will be described. First, the first embodiment will be described with reference to FIGS. 1 and 2. As shown in FIG. 1, the air filter 1 of the present invention is arranged in the air flow 3 in the indoor unit of the air conditioner 2, and the charged filter 4 and the non-charged filter 5 are overlapped in the thickness direction. It is a configuration.

帯電フィルタ4は、気流3の下流側に配置され、非帯電フィルタ5は、気流3の上流側に配置される。これら、帯電フィルタ4および非帯電フィルタ5は、双方とも不織布製である。また、帯電フィルタ4は、厚み方向の表面が正極、裏面が負極となる高配向分極構造を有する。この高配向分極構造について、エレクトレット化した高配向分極電石不織布、厚み方向に揃えて配列した分極構造のため、シート内部および外部に強い電界を作ることができる。また、表面は正負の分極をもっている。 The charging filter 4 is arranged on the downstream side of the air flow 3, and the non-charging filter 5 is arranged on the upstream side of the air flow 3. Both the charging filter 4 and the non-charging filter 5 are made of non-woven fabric. Further, the charging filter 4 has a highly oriented polarization structure in which the front surface in the thickness direction is a positive electrode and the back surface is a negative electrode. Regarding this highly oriented polarization structure, since the electretized highly oriented polarized electret non-woven fabric and the polarization structure arranged in the thickness direction, a strong electric field can be created inside and outside the sheet. Moreover, the surface has positive and negative polarization.

図2で示すように、非帯電フィルタ5は、帯電フィルタ4に比べて大面積に形成されている。例えば、帯電フィルタ4および非帯電フィルタ5は、平面視して矩形形状(略正方形)とし、非帯電フィルタ5が横方向Hおよび縦方向Vにおいて、帯電フィルタ4よりも大きく設定されている。そして、本実施形態では、エアフィルタ1のうち非帯電フィルタ5の四辺部5aを、帯電フィルタ4の四隅に沿って折り曲げている。 As shown in FIG. 2, the non-charged filter 5 is formed in a larger area than the charged filter 4. For example, the charging filter 4 and the non-charging filter 5 have a rectangular shape (substantially square) in a plan view, and the non-charging filter 5 is set to be larger than the charging filter 4 in the horizontal direction H and the vertical direction V. Then, in the present embodiment, the four sides 5a of the non-charged filter 5 of the air filter 1 are bent along the four corners of the charged filter 4.

帯電フィルタ4および非帯電フィルタ5の厚み方向tで重なる部分を、以後、重なり領域6と称す。帯電フィルタ4と非帯電フィルタ5とは、重なり領域6内に形成される接合部8を介して接合されている。このような接合部8は、非帯電フィルタ5を、帯電フィルタ4の四隅に沿って折り曲げた四辺部5aの外側近傍に設け、且つ四辺部5aに沿って設けられている。なお、非帯電フィルタ5を帯電フィルタ4の四隅に沿わせる寸法は3cm程度とされる。 The portion of the charging filter 4 and the non-charging filter 5 that overlap in the thickness direction t is hereinafter referred to as an overlapping region 6. The charging filter 4 and the non-charging filter 5 are joined via a joining portion 8 formed in the overlapping region 6. Such a joining portion 8 is provided with the non-charging filter 5 provided in the vicinity of the outer side of the four-sided portion 5a bent along the four corners of the charging filter 4, and is provided along the four-sided portion 5a. The dimension of the non-charged filter 5 along the four corners of the charged filter 4 is about 3 cm.

また、非帯電フィルタ5の四辺部5aは、エアコンデイショナ2の上流側に取付けられる部分であり、例えば、ベルベットファスナ等の取付手段を介して、エアコンデイショナ2の気流3の外側に着脱自在に取付けられる。 Further, the four side portions 5a of the non-charged filter 5 are portions attached to the upstream side of the air conditioner 2, and can be attached to and detached from the outside of the air flow 3 of the air conditioner 2 via, for example, an attachment means such as a velvet fastener. Can be attached to.

接合部8は、帯電フィルタ4の繊維と非帯電フィルタ5の繊維とが、溶着、又は、互いに絡み合うようにして形成されている。第一の実施形態では、帯電フィルタ4の繊維と非帯電フィルタ5の繊維とが溶着される構成であり、超音波を用いた接着とされる。超音波接着は、溶着物(帯電フィルタ4の繊維と非帯電フィルタ5の繊維)に伝達された超音波振動が溶着物を伝搬することによって、接合面が発熱し、該熱により溶着物が溶解して溶着される。 The joint portion 8 is formed so that the fibers of the charging filter 4 and the fibers of the non-charging filter 5 are welded or entangled with each other. In the first embodiment, the fibers of the charging filter 4 and the fibers of the non-charging filter 5 are welded together, and the fibers are bonded using ultrasonic waves. In ultrasonic adhesion, the ultrasonic vibration transmitted to the welded material (fibers of the charged filter 4 and the fiber of the non-charged filter 5) propagates through the welded material, so that the joint surface generates heat and the welded material is melted by the heat. And welded.

ここで、帯電フィルタ4の厚みは、非帯電フィルタ5の厚みより薄く形成されている。また、帯電フィルタ4の目付は、非帯電フィルタ5の目付より小さく設定されている。 Here, the thickness of the charging filter 4 is formed to be thinner than the thickness of the non-charging filter 5. Further, the basis weight of the charging filter 4 is set smaller than the basis weight of the non-charging filter 5.

具体的に、帯電フィルタ4の厚みは0、1~0、5mmであり、好ましくは0、2mmとされる。帯電フィルタ4の目付は5~30g/mであり、好ましくは15g/mとされる。また、非帯電フィルタ5の厚みは、1~10mmであり、好ましくは5mmとされる。非帯電フィルタ5の目付は50~100g/mであり、好ましく70g/mとされる。 Specifically, the thickness of the charging filter 4 is 0, 1 to 0, 5 mm, preferably 0, 2 mm. The basis weight of the charging filter 4 is 5 to 30 g / m 2 , preferably 15 g / m 2 . The thickness of the non-charged filter 5 is 1 to 10 mm, preferably 5 mm. The basis weight of the non-charged filter 5 is 50 to 100 g / m 2 , preferably 70 g / m 2 .

非帯電フィルタ5の繊維は、少なくとも酸化チタンとジメチル・フェニル・スルファルドを含むコーティング剤でコーティングされている。また、コーティングとして、SiO(二酸化ケイ素)、P(五酸化ニリン)、Al(酸化アルミニウム)、TiO(酸化チタン)、NaO(酸化ナトリウム)の水溶性成分とされている。 The fibers of the non-charged filter 5 are coated with a coating agent containing at least titanium oxide and dimethyl phenyl sulfard. Further, as a coating, water-soluble components such as SiO 2 (silicon dioxide), P2 O 5 (niline pentoxide), Al 2 O 3 (aluminum oxide), TiO 2 (titanium oxide), and Na 2 O ( sodium oxide) are used. Has been done.

上記構成のエアフィルタ1において、上流側の非帯電フィルタ5によって油分が捕集されるため、下流側の帯電フィルタ4への油分の付着が抑制される。よって、帯電フィルタ4の捕集性能を維持でき、エアフィルタ1としての捕集性能を持続させることができる。 In the air filter 1 having the above configuration, the oil content is collected by the non-charged filter 5 on the upstream side, so that the adhesion of the oil content to the charged filter 4 on the downstream side is suppressed. Therefore, the collection performance of the charging filter 4 can be maintained, and the collection performance of the air filter 1 can be maintained.

また、帯電フィルタ4の目付は、非帯電フィルタ5の目付より小さい。これにより、気流3の上流側の非帯電フィルタ5で先に大きいもの(物質)を捕集し、下流側の帯電フィルタ4で残りの小さいものを捕集することで、高い捕集性能が発揮される。 Further, the basis weight of the charging filter 4 is smaller than the basis weight of the non-charging filter 5. As a result, the non-charged filter 5 on the upstream side of the airflow 3 collects the large substances (substances) first, and the charged filter 4 on the downstream side collects the remaining small substances, thereby exhibiting high collection performance. Will be done.

帯電フィルタ4の厚みは、非帯電フィルタ5の厚みより薄い。このため、目付の小さい帯電フィルタ4を、目付の大きい非帯電フィルタ5よりも薄い厚みとすることで、気流3の圧力損失を制御することができる。 The thickness of the charging filter 4 is thinner than the thickness of the non-charging filter 5. Therefore, the pressure loss of the airflow 3 can be controlled by making the charging filter 4 having a small basis weight thinner than the non-charging filter 5 having a large basis weight.

帯電フィルタ4と非帯電フィルタ5とは、厚み方向で重なり領域6内に形成される接合部8を介して接合され、接合部8は、非帯電フィルタ5を、帯電フィルタ4の四隅に沿って折り曲げた四辺部5aの外側近傍に設け、且つ四辺部5aに沿って設けられている。このため、捕集性能を確保しつつ両フィルタを強固に接合することができる。さらに接合部8は、帯電フィルタ4の繊維と非帯電フィルタ5の繊維とが溶着して形成されている。このため、帯電フィルタ4と非帯電フィルタ5とが、しっかりと接合され、且つ帯電フィルタ4や非帯電フィルタ5が破損しにくく、しかも美観的にも優れる。 The charging filter 4 and the non-charging filter 5 are joined via a joining portion 8 formed in the overlapping region 6 in the thickness direction, and the joining portion 8 connects the non-charging filter 5 along the four corners of the charging filter 4. It is provided near the outer side of the bent four-sided portion 5a, and is provided along the four-sided portion 5a. Therefore, both filters can be firmly joined while ensuring the collection performance. Further, the joint portion 8 is formed by welding the fibers of the charging filter 4 and the fibers of the non-charging filter 5. Therefore, the charging filter 4 and the non-charging filter 5 are firmly joined to each other, the charging filter 4 and the non-charging filter 5 are not easily damaged, and the appearance is excellent.

また、帯電フィルタ4は、厚み方向の表面が正極、裏面が負極となる高配向分極構造を有する。このため、帯電フィルタ4によって高い捕集性能を発揮できる。 Further, the charging filter 4 has a highly oriented polarization structure in which the front surface in the thickness direction is a positive electrode and the back surface is a negative electrode. Therefore, the charging filter 4 can exhibit high collection performance.

さらに、非帯電フィルタ5の繊維は、少なくとも酸化チタンとジメチル・フェニル・スルファルドを含むコーティング剤でコーティングされている。このため、有害汚染物質を軽減し、埃や黴などの汚れを捕集し、ウィルスや菌を捕集し、消毒することができる。 Further, the fibers of the non-charged filter 5 are coated with a coating agent containing at least titanium oxide and dimethyl phenyl sulfard. Therefore, it is possible to reduce harmful pollutants, collect dirt such as dust and mold, collect viruses and fungi, and disinfect them.

第一の実施形態では、帯電フィルタ4および非帯電フィルタ5は、平面して矩形形状(略正方形)とされたが、図3で示すように、長方形であってもよい。 In the first embodiment, the charging filter 4 and the non-charging filter 5 have a rectangular shape (substantially square) in a plane, but may be rectangular as shown in FIG.

本考案は、上記実施形態に限定されるものではない。ここで、図4、図5に基づいて第二の実施形態を説明する。帯電フィルタ4と非帯電フィルタ5の構成については、第一の実施形態と同様である。 The present invention is not limited to the above embodiment. Here, the second embodiment will be described with reference to FIGS. 4 and 5. The configurations of the charging filter 4 and the non-charging filter 5 are the same as those in the first embodiment.

図4および図5で示すように、非帯電フィルタ5は、帯電フィルタ4に比べて大面積に形成されている。例えば、帯電フィルタ4および非帯電フィルタ5は、平面視して矩形形状(略正方形)とし、非帯電フィルタ5が横方向Hおよび縦方向Vにおいて、帯電フィルタ4よりも大きく設定されている。 As shown in FIGS. 4 and 5, the non-charged filter 5 is formed in a larger area than the charged filter 4. For example, the charging filter 4 and the non-charging filter 5 have a rectangular shape (substantially square) in a plan view, and the non-charging filter 5 is set to be larger than the charging filter 4 in the horizontal direction H and the vertical direction V.

また、非帯電フィルタ5の余剰部分7(帯電フィルタ4より横方向Hおよび縦方向Vに広い部分)は、エアコンデイショナ2の上流側に取付けられる部分であり、例えば、ベルベットファスナ等の取付手段を介して、エアコンデイショナ2の気流3の外側に着脱自在に取付けられる。 Further, the surplus portion 7 of the non-charging filter 5 (a portion wider in the horizontal direction H and the vertical direction V than the charging filter 4) is a portion mounted on the upstream side of the air conditioner 2 and is, for example, a mounting means such as a velvet fastener. It is detachably attached to the outside of the airflow 3 of the air conditioner 2 via the air conditioner 2.

ところで、上記第一の実施形態では、接合部8は、超音波を用いて四辺部5aの外側近傍に設けたが、第二の実施形態では、接合部8は、重なり領域6内において所定の間隔を空けて複数形成されたものである。これには、超音波ホッチキス(ホッチキス超音波)が用いられる。すなわち、図5において、超音波接着部分、すなわち接合部8は、点状を連ねた線として表されている。 By the way, in the first embodiment, the joint portion 8 is provided in the vicinity of the outer side of the four side portions 5a by using ultrasonic waves, but in the second embodiment, the joint portion 8 is predetermined in the overlapping region 6. It is formed in multiples at intervals. For this, an ultrasonic stapler (stapler ultrasonic wave) is used. That is, in FIG. 5, the ultrasonically bonded portion, that is, the joint portion 8, is represented as a line connecting dots.

この接合部8は、重なり領域6内において、横方向Hおよび縦方向Vに、帯電フィルタ4と非帯電フィルタ5とが確実に接合されるように、所定の間隔を空けて複数形成されている。 A plurality of the joining portions 8 are formed in the overlapping region 6 at predetermined intervals so that the charging filter 4 and the non-charging filter 5 are surely joined in the horizontal direction H and the vertical direction V. ..

帯電フィルタ4と非帯電フィルタ5とは、厚み方向で重なり領域6内に形成される点状の接合部8を介して接合されており、接合部8は、重なり領域6内において所定の間隔を空けて複数形成されている。このため、捕集性能を確保しつつ両フィルタを強固に接合することができる。さらに接合部8は、帯電フィルタ4の繊維と非帯電フィルタ5の繊維とが溶着して形成されている。このため、帯電フィルタ4の繊維と非帯電フィルタ5とが、しっかりと接合される。 The charging filter 4 and the non-charging filter 5 are joined via a point-shaped joining portion 8 formed in the overlapping region 6 in the thickness direction, and the joining portion 8 has a predetermined interval in the overlapping region 6. Multiple pieces are formed in a space. Therefore, both filters can be firmly joined while ensuring the collection performance. Further, the joint portion 8 is formed by welding the fibers of the charging filter 4 and the fibers of the non-charging filter 5. Therefore, the fibers of the charging filter 4 and the non-charging filter 5 are firmly joined.

第二の実施形態では、帯電フィルタ4および非帯電フィルタ5は、平面して矩形形状(略正方形)とされたが、図6で示すように、長方形であってもよい。 In the second embodiment, the charging filter 4 and the non-charging filter 5 have a rectangular shape (substantially square) in a plane, but may be rectangular as shown in FIG.

なお、第一の実施形態および第二の実施形態では、帯電フィルタ4と非帯電フィルタ5との接合は超音波接着とされた。しかしながら、接合部8は、帯電フィルタ4の繊維と非帯電フィルタ5の繊維とが互いに絡み合うようにして接合することもできる。具体的には、帯電フィルタ4と非帯電フィルタ5のとの接合部8は、ニードルパンチによって形成することもできる。 In the first embodiment and the second embodiment, the bonding between the charging filter 4 and the non-charging filter 5 is ultrasonic bonding. However, the joining portion 8 can also be joined so that the fibers of the charging filter 4 and the fibers of the non-charging filter 5 are intertwined with each other. Specifically, the joint portion 8 between the charged filter 4 and the non-charged filter 5 can also be formed by needle punching.

上記第一の実施形態および第二の実施形態では、エアフィルタとしてエアコンデイショナ2の室内機に用いられるものとして説明したが、これに限定されず、例えば換気扇など、気流3を用いるものであれば、その用途は問わない。 In the first embodiment and the second embodiment, the air filter has been described as being used for the indoor unit of the air conditioner 2 as an air filter, but the present invention is not limited to this, and the air flow 3 may be used, for example, a ventilation fan. If so, its use does not matter.
