Description

本発明は、例えば自動車等に搭載される車両用空調装置のエアフィルタ構造に関するものである。 The present invention relates to an air filter structure of a vehicle air conditioner mounted on, for example, an automobile.

従来から、自動車に搭載される車両用空調装置には、空気を濾過するためのエアフィルタが設けられている。 Conventionally, an air filter for filtering air is provided in a vehicle air conditioner mounted on an automobile.

エアフィルタの濾過性能向上と長寿命化の両立を図るためには、濾過面積をできるだけ大きく確保すべく大きな濾材とするのが好ましい。ところが、エアフィルタは定期的な交換が必要であり、交換時に、空調装置の周囲に車両側の機器が搭載されている場合にはエアフィルタが大きいと交換作業が困難になる。 In order to achieve both the improvement of the filtration performance of the air filter and the extension of the service life, it is preferable to use a large filter medium so as to ensure as large a filtration area as possible. However, the air filter needs to be replaced periodically, and if the equipment on the vehicle side is mounted around the air conditioner at the time of replacement, the replacement work becomes difficult if the air filter is large.

そこで、例えば、特許文献１のエアフィルタ構造では、ケーシング内に配設されるフィルタを２つのフィルタ部材に分割し、一方のフィルタ部材をケーシングのフィルタ挿入孔からケーシング内に挿入してケーシング内に設けられているガイドに沿って押し上げた後、他方のフィルタ部材をフィルタ挿入孔から挿入するようにしている。 Therefore, for example, in the air filter structure disclosed in Patent Document 1, the filter disposed in the casing is divided into two filter members, and one filter member is inserted into the casing from the filter insertion hole of the casing, and is then inserted into the casing. After being pushed up along the provided guide, the other filter member is inserted from the filter insertion hole.

特許文献１のものでは、初めに挿入したフィルタ部材をケーシング内のガイドで案内するようにしているが、作業者は目視できない状況なので、フィルタ部材をガイドに沿わせること自体が困難である。また、２回分の挿入作業が必要で交換作業が煩雑である。 In the thing of patent document 1, although the filter member inserted initially is guided with the guide in a casing, since it is the situation which an operator cannot visually observe, it is difficult to make a filter member follow a guide itself. Moreover, the insertion work for 2 times is required and the replacement work is complicated.

この特許文献１に対し、例えば、特許文献２、３では、エアフィルタの濾材を縮めてフィルタ挿入孔からケーシング内に挿入した後、ケーシング内で展開させるようにしており、これによれば、ガイドに沿わせる作業や、複数回の挿入作業が不要になるという利点がある。 In contrast to this Patent Document 1, for example, in Patent Documents 2 and 3, the filter medium of the air filter is contracted and inserted into the casing through the filter insertion hole, and then deployed in the casing. There is an advantage that it is not necessary to carry out the operation along the line and to insert a plurality of times.

ところで、特許文献２、３のエアフィルタ構造では、濾材を縮めた後、展開するようにしているが、濾材を一旦縮めてしまうと、その縮まった形状が一部に残ってしまい、後に所期の形状で展開しない場合が考えられ、空気の濾過性能に悪影響を与えてしまう恐れがある。 By the way, in the air filter structures of Patent Documents 2 and 3, the filter medium is expanded after being contracted. However, once the filter medium is contracted, the contracted shape remains in a part, and later is expected. The shape may not be developed, and there is a risk of adversely affecting the air filtration performance.

また、濾材を縮めながらフィルタ挿入孔に挿入する際に、濾材に無理な力がかかって濾材が損傷する恐れもある。 Further, when the filter medium is inserted into the filter insertion hole while being contracted, there is a possibility that the filter medium is damaged by applying an excessive force to the filter medium.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、エアフィルタをフィルタ挿入孔に挿入する場合に、濾材に永久変形や損傷を与えることなく、しかも、作業性を良好にすることにある。 The present invention has been made in view of the above points, and the object of the present invention is to prevent the filter medium from being permanently deformed or damaged when the air filter is inserted into the filter insertion hole, and to improve workability. It is to improve.

上記目的を達成するために、本発明では、エアフィルタが第１及び第２フィルタ部材を備えるものとし、第１フィルタ部材の濾材を第２フィルタ部材の濾材に対してスライド可能に配置した。 In order to achieve the above object, in the present invention, the air filter includes the first and second filter members, and the filter medium of the first filter member is slidably disposed with respect to the filter medium of the second filter member.

第１の発明は、車両用空調装置の空気通路を構成する空気通路構成部材と、上記空気通路構成部材の空気通路に配設されるエアフィルタとを備え、上記空気通路構成部材の壁部には、該壁部を貫通するフィルタ挿入孔が形成され、該フィルタ挿入孔から上記エアフィルタを上記空気通路に挿入可能に構成された車両用空調装置のエアフィルタ構造において、上記エアフィルタは、濾材を有する第１及び第２フィルタ部材を備え、上記第１フィルタ部材の濾材は、上記第２フィルタ部材の濾材の厚み方向一側の面に、該面に沿ってスライド可能に配置されていることを特徴とするものである。 1st invention is equipped with the air path structural member which comprises the air path of a vehicle air conditioner, and the air filter arrange | positioned in the air path of the said air path structural member, The wall part of the said air path structural member In the air filter structure of a vehicle air conditioner, in which a filter insertion hole penetrating the wall portion is formed and the air filter can be inserted into the air passage from the filter insertion hole, the air filter includes a filter medium And the filter material of the first filter member is slidably disposed along the surface on one side in the thickness direction of the filter material of the second filter member. It is characterized by.

この構成によれば、第１フィルタ部材の濾材が第２フィルタ部材の濾材の厚み方向に重なることになるので、濾過面積の大きな濾材を小さくしておくことが可能になり、空調装置の周囲に様々な機器等が配設されている状況下でエアフィルタをフィルタ挿入孔から空気通路へ容易に挿入可能になる。挿入前には第１及び第２フィルタ部材の濾材を単に重ねておけばよいので、従来例のように縮めたり、無理な力をかけずに済む。 According to this configuration, since the filter medium of the first filter member overlaps the thickness direction of the filter medium of the second filter member, it is possible to keep the filter medium having a large filtration area small and around the air conditioner. The air filter can be easily inserted into the air passage from the filter insertion hole under a situation where various devices are disposed. Prior to insertion, the filter media of the first and second filter members may be simply overlapped, so that it is not necessary to shrink or apply excessive force as in the conventional example.

そして、空気通路への挿入後には、第１フィルタ部材の濾材を第２フィルタ部材の濾材に沿ってスライドさせることで、濾過面積の大きな濾材が得られる。第１フィルタ部材の濾材をスライドさせる際、第２フィルタ部材の濾材が第１フィルタ部材の濾材の案内として機能することになるので、作業者は目視できない状況でも作業が簡単に行える。 Then, after insertion into the air passage, a filter medium having a large filtration area is obtained by sliding the filter medium of the first filter member along the filter medium of the second filter member. When the filter medium of the first filter member is slid, the filter medium of the second filter member functions as a guide for the filter medium of the first filter member, so that the work can be easily performed even in a situation where the operator cannot see.

また、空気通路内のエアフィルタを取り出す際には、第１フィルタ部材の濾材と第２フィルタ部材の濾材とが重るように第１フィルタ部材の濾材をスライドさせることで濾材が小さくなり、容易に取り出すことが可能になる。 Further, when taking out the air filter in the air passage, the filter medium of the first filter member is slid so that the filter medium of the first filter member and the filter medium of the second filter member are overlapped with each other. It becomes possible to take out.

第２の発明は、第１の発明において、第１及び第２フィルタ部材の濾材には、プリーツ形状となるように複数の折り目が成形されており、上記第１フィルタ部材の濾材は、該濾材のプリーツ形状と上記第２フィルタ部材の濾材のプリーツ形状とが略一致するように、かつ、該第２フィルタ部材の濾材に対して折り目の延びる方向にスライド可能に重ね合わされていることを特徴とするものである。 According to a second invention, in the first invention, the filter medium of the first and second filter members is formed with a plurality of folds so as to have a pleat shape, and the filter medium of the first filter member is the filter medium. The pleat shape of the second filter member and the pleat shape of the filter medium of the second filter member are substantially coincided with each other, and are slidably overlapped with the filter medium of the second filter member in a direction in which the fold extends. To do.

この構成によれば、第１フィルタ部材の濾材を第２フィルタ部材の濾材の厚み方向に重ねて両フィルタ部材を空気通路に挿入した状態で第１フィルタ部材の濾材をスライドさせる際、第２フィルタ部材の濾材の折り目の延びる方向にスライドさせればよいので、第１フィルタ部材の濾材を所定方向に確実に、かつ、容易にスライドさせることが可能になる。 According to this configuration, when the filter medium of the first filter member is slid with the filter medium of the first filter member overlapped in the thickness direction of the filter medium of the second filter member and both filter members are inserted into the air passage, Since it is only necessary to slide in the direction in which the fold of the filter medium of the member extends, the filter medium of the first filter member can be reliably and easily slid in a predetermined direction.

また、空気通路内のエアフィルタを取り出す際にも、第１フィルタ部材の濾材を同様に容易にスライドさせて第２フィルタ部材の濾材と重ねることが可能になる。 Further, when the air filter in the air passage is taken out, the filter medium of the first filter member can be easily slid and overlapped with the filter medium of the second filter member.

第３の発明は、第１または２の発明において、空気通路構成部材は、フィルタ挿入孔を開閉するカバー部材を備え、第１フィルタ部材には、該第１フィルタ部材が空気通路に配置された状態でフィルタ挿入孔側となる部位に被係合部が設けられ、上記カバー部材には、上記第１フィルタ部材の被係合部に係合する係合部が設けられていることを特徴とするものである。 According to a third aspect, in the first or second aspect, the air passage component member includes a cover member that opens and closes the filter insertion hole, and the first filter member is disposed in the air passage. An engaged portion is provided in a portion on the filter insertion hole side in the state, and the cover member is provided with an engaging portion that engages with the engaged portion of the first filter member. To do.

この構成によれば、第１及び第２フィルタ部材の濾材を重ね合わせた状態でフィルタ挿入孔から挿入すると、第１フィルタ部材の被係合部がフィルタ挿入孔側に位置することなる。この被係合部は、カバー部材の係合部に係合するので、カバー部材と第１フィルタ部材とを一体化することが可能になる。これにより、カバー部材を用いて第１フィルタ部材の濾材をスライドさせることが可能になる。 According to this configuration, when the filter media of the first and second filter members are overlapped and inserted from the filter insertion hole, the engaged portion of the first filter member is positioned on the filter insertion hole side. Since the engaged portion engages with the engaging portion of the cover member, the cover member and the first filter member can be integrated. Thereby, it becomes possible to slide the filter medium of the first filter member using the cover member.

第４の発明は、第３の発明において、空気通路構成部材には、カバー部材をフィルタ挿入孔の開閉方向に案内するための案内部が設けられ、上記案内部の案内方向は、第１フィルタ部材の濾材のスライド方向であることを特徴とするものである。 In a fourth aspect based on the third aspect, the air passage component member is provided with a guide portion for guiding the cover member in the opening / closing direction of the filter insertion hole, and the guide direction of the guide portion is the first filter. It is a sliding direction of the filter medium of a member, It is characterized by the above-mentioned.

この構成によれば、カバー部材の案内方向が第１フィルタ部材の濾材のスライド方向であるので、カバー部材の係合部を第１フィルタ部材の被係合部に係合させた状態でカバー部材を開閉方向に操作するだけで、第１フィルタ部材の濾材をスライドさせることが可能になる。 According to this configuration, since the guide direction of the cover member is the sliding direction of the filter medium of the first filter member, the cover member is engaged with the engaging portion of the cover member engaged with the engaged portion of the first filter member. The filter medium of the first filter member can be slid only by operating in the opening / closing direction.

第１の発明によれば、エアフィルタが第１及び第２フィルタ部材を備えるものとし、第１フィルタ部材の濾材を第２フィルタ部材の濾材に厚み方向に重ねた状態でスライド可能にしたので、エアフィルタをフィルタ挿入孔から空気通路に挿入する場合に、濾材に変形や損傷を与えることなく、しかも、作業性を良好にすることができる。 According to the first invention, the air filter is provided with the first and second filter members, and the filter medium of the first filter member is made slidable in a state of being superimposed on the filter medium of the second filter member in the thickness direction. When the air filter is inserted into the air passage from the filter insertion hole, the filter medium is not deformed or damaged, and the workability can be improved.

第２の発明によれば、第１フィルタ部材の濾材のプリーツ形状と第２フィルタ部材の濾材のプリーツ形状とを略一致させ、第１フィルタ部材の濾材を、第２フィルタ部材の濾材に対して折り目の延びる方向にスライド可能に重ね合わせたので、第１フィルタ部材の濾材を所定方向にスライドさせる作業を確実に、かつ、容易に行うことができ、作業性をより一層良好にできる。 According to the second invention, the pleat shape of the filter medium of the first filter member and the pleat shape of the filter medium of the second filter member are substantially matched, and the filter medium of the first filter member is made to the filter medium of the second filter member. Since the folds are slidably overlapped in the extending direction of the fold, the operation of sliding the filter medium of the first filter member in the predetermined direction can be performed reliably and easily, and the workability can be further improved.

第３の発明によれば、フィルタ挿入孔を開閉するカバー部材を用いて第１フィルタ部材の濾材をスライドさせることができるので、作業性をより一層良好にできる。 According to the third invention, since the filter medium of the first filter member can be slid using the cover member that opens and closes the filter insertion hole, the workability can be further improved.

第４の発明によれば、カバー部材をフィルタ挿入孔の開閉方向に案内するための案内部を設け、この案内部によるカバー部材の案内方向を第１フィルタ部材の濾材のスライド方向としたので、カバー部材の開閉動作に連動させて第１フィルタ部材の濾材をスライドさせることができる。 According to the fourth invention, the guide member for guiding the cover member in the opening / closing direction of the filter insertion hole is provided, and the guide direction of the cover member by the guide portion is the sliding direction of the filter medium of the first filter member. The filter medium of the first filter member can be slid in conjunction with the opening / closing operation of the cover member.

以下、本発明の実施形態を図面に基づいて詳細に説明する。尚、以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものではない。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

図１は、本発明の実施形態にかかる車両用空調装置のフィルタ構造１を示すものである。車両用空調装置１００は、図示しないが例えば自動車の車室内に配設されたインストルメントパネル内に搭載されるようになっている。この空調装置１００は、冷却用及び加熱用熱交換器（図示せず）を収容する樹脂製のケーシング１０１を備えている。ケーシング１０１には、図示しないが、空調用空気を導入するための導入口と、調和空気の吹出口とが形成されている。また、ケーシング１０１の内部には、導入口から吹出口まで延びる空気通路Ｒが形成されており、導入口から導入された空調用空気は空気通路Ｒを流れる間に上記熱交換器によって温度調節されて吹出口から車室の各部に供給される。上記ケーシング１０１は本発明の空気通路構成部材である。 FIG. 1 shows a filter structure 1 of a vehicle air conditioner according to an embodiment of the present invention. Although not shown, the vehicle air conditioner 100 is mounted, for example, in an instrument panel disposed in a vehicle interior of an automobile. The air conditioner 100 includes a resin casing 101 that houses cooling and heating heat exchangers (not shown). Although not shown, the casing 101 is formed with an inlet for introducing air for air conditioning and an outlet for conditioned air. An air passage R extending from the inlet to the outlet is formed inside the casing 101, and the temperature of the air-conditioning air introduced from the inlet is adjusted by the heat exchanger while flowing through the air passage R. Then, it is supplied to each part of the passenger compartment from the outlet. The casing 101 is an air passage constituent member of the present invention.

フィルタ構造１は、ケーシング１０１と、ケーシング１０１内に配設されるエアフィルタ１０とを備えている。ケーシング１０１の空気通路Ｒにおける熱交換器よりも上流側には、エアフィルタ１０を配設するためのフィルタ配設部Ｒ１が設けられている。このフィルタ配設部Ｒ１を囲むケーシング１０１の周壁部は、図２に示すように、断面が略矩形状とされており、上壁部１０１ａ、左側壁部１０１ｂ、右側壁部１０１ｃ及び底壁部１０１ｄを備えている。 The filter structure 1 includes a casing 101 and an air filter 10 disposed in the casing 101. On the upstream side of the heat exchanger in the air passage R of the casing 101, a filter disposition portion R1 for disposing the air filter 10 is provided. As shown in FIG. 2, the peripheral wall portion of the casing 101 surrounding the filter arrangement portion R1 has a substantially rectangular cross section, and includes an upper wall portion 101a, a left wall portion 101b, a right wall portion 101c, and a bottom wall portion. 101d.

エアフィルタ１０の上下寸法は、フィルタ配設部Ｒ１の上下寸法と略同じに設定され、また、エアフィルタ１０の左右寸法は、フィルタ配設部Ｒ１の左右寸法と略同じに設定されている。そして、エアフィルタ１０は、フィルタ配設部Ｒ１を横切るように配置されて空調用空気の略全量を濾過するようになっている。 The vertical dimension of the air filter 10 is set to be substantially the same as the vertical dimension of the filter arrangement portion R1, and the horizontal dimension of the air filter 10 is set to be substantially the same as the horizontal dimension of the filter arrangement portion R1. And the air filter 10 is arrange | positioned so that the filter arrangement | positioning part R1 may be crossed, and it filters the substantially whole quantity of air for an air conditioning.

尚、この実施形態の説明では、車両前側を単に「前」といい、車両後側を単に「後」といい、車両左側を単に「左」といい、車両右側を単に「右」というものとする。 In the description of this embodiment, the front side of the vehicle is simply referred to as “front”, the rear side of the vehicle is simply referred to as “rear”, the left side of the vehicle is simply referred to as “left”, and the right side of the vehicle is simply referred to as “right”. To do.

図３及び図４に示すように、ケーシング１０１の右側壁部１０１ｃには、該右側壁部１０１ｃを貫通するフィルタ挿入孔１１が形成されている。フィルタ挿入孔１１は、カバー部材１２によって開閉されるようになっている。 As shown in FIGS. 3 and 4, the right side wall portion 101 c of the casing 101 is formed with a filter insertion hole 11 that passes through the right side wall portion 101 c. The filter insertion hole 11 is opened and closed by a cover member 12.

フィルタ挿入孔１１は、右側壁部１０１ｃの上下方向中央部近傍から下端部まで延びる上下方向に長い略矩形状に形成されている。つまり、フィルタ挿入孔１１の上下寸法は、エアフィルタ１０の上下寸法よりも短く、エアフィルタ１０の上下寸法の約１／２程度に設定されている。その理由は、ケーシング１０１外部の右側壁部１０１ｃの上側近傍には、車両側の他の機器が配置されており、その機器の存在によってケーシング１０１の上側からはエアフィルタ１０の挿入や取り出しができないためである。 The filter insertion hole 11 is formed in a substantially rectangular shape that is long in the vertical direction and extends from the vicinity of the center in the vertical direction of the right side wall 101c to the lower end. That is, the vertical dimension of the filter insertion hole 11 is shorter than the vertical dimension of the air filter 10 and is set to about ½ of the vertical dimension of the air filter 10. The reason is that another device on the vehicle side is arranged near the upper side of the right side wall portion 101c outside the casing 101, and the air filter 10 cannot be inserted or removed from the upper side of the casing 101 due to the presence of the device. Because.

フィルタ挿入孔１１の前縁部及び後縁部は、上下方向に直線状に、かつ、互いに略平行に延びている。フィルタ挿入孔１１の上縁部は、前後方向に略直線状に延びている。フィルタ挿入孔１１の下部は、底壁部１０１ｄの右端部に亘って形成されている。 The front edge portion and the rear edge portion of the filter insertion hole 11 extend linearly in the vertical direction and substantially parallel to each other. The upper edge portion of the filter insertion hole 11 extends substantially linearly in the front-rear direction. The lower part of the filter insertion hole 11 is formed over the right end part of the bottom wall part 101d.

右側壁部１０１ｃ外面におけるフィルタ挿入孔１１の前縁部には、カバー部材１２を開閉方向である上下方向に案内するための前側レール（案内部）１３が設けられている。前側レール１３は、フィルタ挿入孔１１の前縁部に沿って上下方向に延びており、下縁部が、フィルタ挿入孔１１の上下方向中間部に位置し、フィルタ挿入孔１１の下部には、前側レール１３が形成されない領域がある。 A front rail (guide portion) 13 for guiding the cover member 12 in the up-down direction which is the opening / closing direction is provided at the front edge portion of the filter insertion hole 11 on the outer surface of the right side wall portion 101c. The front rail 13 extends in the vertical direction along the front edge portion of the filter insertion hole 11, and the lower edge portion is positioned at the middle portion in the vertical direction of the filter insertion hole 11. There is a region where the front rail 13 is not formed.

前側レール１３は、ケーシング１０１外へ突出した後、その先端側が前側へ向けて折り曲げられており、水平方向の断面形状が略Ｌ字状となっている。また、右側壁部１０１ｃ外面におけるフィルタ挿入孔１１の後縁部には、前側レール１３と同様に、カバー部材１２を案内するための後側レール（案内部）１４が該前側レール１３と略平行に設けられている。尚、前側及び後側レール１３，１４の一方を省略することも可能である。 After the front rail 13 protrudes out of the casing 101, the front end side thereof is bent toward the front side, and the horizontal cross-sectional shape is substantially L-shaped. A rear rail (guide portion) 14 for guiding the cover member 12 is substantially parallel to the front rail 13 at the rear edge of the filter insertion hole 11 on the outer surface of the right side wall 101c. Is provided. One of the front and rear rails 13 and 14 can be omitted.

カバー部材１２は、フィルタ挿入孔１１よりも大型の矩形板状に形成された樹脂材からなるものである。カバー部材１２の前縁部には、上記前側レール１３が嵌る前溝１６が形成されている。前溝１６は、前側レール１３の水平方向の断面形状に対応した略Ｌ字状の断面を有している。また、カバー部材１２の後縁部には、同様に上記後側レール１４が嵌る後溝１７が形成されている。これら前溝１６及び後溝１７は、互いに略平行に延びている。前溝１６及び後溝１７の上端部は開放されており、この上端の開放部分から前側及び後側レール１３，１４の下端部を前溝１６及び後溝１７に挿入することができるようになっている。 The cover member 12 is made of a resin material formed in a rectangular plate shape larger than the filter insertion hole 11. A front groove 16 into which the front rail 13 is fitted is formed at the front edge of the cover member 12. The front groove 16 has a substantially L-shaped cross section corresponding to the horizontal cross section of the front rail 13. Similarly, a rear groove 17 into which the rear rail 14 is fitted is formed at the rear edge of the cover member 12. The front groove 16 and the rear groove 17 extend substantially parallel to each other. The upper ends of the front groove 16 and the rear groove 17 are open, and the lower ends of the front and rear rails 13 and 14 can be inserted into the front groove 16 and the rear groove 17 from the open portion of the upper end. ing.

前側及び後側レール１３，１４が前溝１６及び後溝１７に嵌った状態で、カバー部材１２は、上下方向にのみ移動可能となり、前後方向や左右方向には移動不能となる。 With the front and rear rails 13 and 14 fitted in the front groove 16 and the rear groove 17, the cover member 12 can move only in the vertical direction, and cannot move in the front-rear direction and the left-right direction.

カバー部材１２の上部近傍には、摘み部１８がケーシング１０１外へ突出するように形成されている。摘み部１８は、カバー部材１２をケーシング１０１に取り付ける際に作業者が指で摘んで操作するためのものであり、カバー部材１２の開閉方向（上下方向）と略直交する方向（水平方向）に延びる厚肉板状に形成されている。図４や図７に示すように、摘み部１８の内部には、中空部Ｓが設けられており、この中空部Ｓは、カバー部材１２におけるケーシング１０１内側の面に開口している。 Near the upper part of the cover member 12, a knob 18 is formed so as to protrude out of the casing 101. The knob 18 is for an operator to grip and operate the cover member 12 with a finger when attaching the cover member 12 to the casing 101, and in a direction (horizontal direction) substantially orthogonal to the opening / closing direction (vertical direction) of the cover member 12. It is formed in a thick plate shape that extends. As shown in FIG. 4 and FIG. 7, a hollow portion S is provided inside the knob portion 18, and this hollow portion S opens on the surface of the cover member 12 inside the casing 101.

図４に示すように、カバー部材１２の下端部には、左側へ延出する延出部２０が形成されている。この延出部２０は、フィルタ挿入孔１１の下端部を下方から閉塞するための部分であり、閉塞状態でケーシング１０１の底壁部１０１ｄ外面に当接するようになっている。 As shown in FIG. 4, an extension 20 that extends to the left is formed at the lower end of the cover member 12. The extending portion 20 is a portion for closing the lower end portion of the filter insertion hole 11 from below, and comes into contact with the outer surface of the bottom wall portion 101d of the casing 101 in the closed state.

次に、上記のように構成された車両用空調装置のフィルタ構造１において新品のエアフィルタ１０を取り付ける場合について説明する。尚、古いエアフィルタはケーシング１０１から予め取り出しているものとする。 Next, the case where the new air filter 10 is attached in the filter structure 1 of the vehicle air conditioner configured as described above will be described. It is assumed that the old air filter has been taken out from the casing 101 in advance.

新品のエアフィルタ１０は、図８に示すように、第１枠状部材３２の内側に第２枠状部材４２が嵌入されて縮小状態となっている。縮小状態では、第１濾材３１と第２濾材４１との大部分が互いに厚み方向に重なっている。 As shown in FIG. 8, the new air filter 10 is in a contracted state with the second frame-shaped member 42 fitted inside the first frame-shaped member 32. In the reduced state, most of the first filter medium 31 and the second filter medium 41 overlap each other in the thickness direction.

エアフィルタ１０を縮小状態のまま、ケーシング１０１のフィルタ挿入孔１１からフィルタ配設部Ｒ１へ挿入していく。このようにエアフィルタ１０を縮小状態のままフィルタ配設部Ｒ１に挿入できるので、ケーシング１０１の周囲に他の機器が存在していても、濾過面積の広いエアフィルタ１０をフィルタ配設部Ｒ１へ挿入できる。 The air filter 10 is inserted into the filter disposition portion R1 from the filter insertion hole 11 of the casing 101 with the air filter 10 in a reduced state. Thus, since the air filter 10 can be inserted into the filter placement portion R1 in a reduced state, the air filter 10 having a wide filtration area can be connected to the filter placement portion R1 even if other devices exist around the casing 101. Can be inserted.

図３及び図４に示すように、縮小状態のエアフィルタ１０がフィルタ配設部Ｒ１へ挿入されると、エアフィルタ１０の突板部３２ｄがケーシング１０１のフィルタ挿入孔１１内に位置する。このとき、突板部３２ｄの突出長さをフィルタ挿入孔１１からケーシング１０１の外部へ飛び出すように設定しておくのが好ましい。 As shown in FIGS. 3 and 4, when the reduced air filter 10 is inserted into the filter placement portion R <b> 1, the protruding plate portion 32 d of the air filter 10 is positioned in the filter insertion hole 11 of the casing 101. At this time, it is preferable to set the protruding length of the protruding plate portion 32d so as to protrude from the filter insertion hole 11 to the outside of the casing 101.

エアフィルタ１０の挿入後、図７に示すように、カバー部材１２をエアフィルタ１０に接近させていき、図１０に示すように、カバー部材１２の摘み部１８の中空部Ｓにエアフィルタ１０の突板部３２ｄを挿入する。これにより、カバー部材１２の摘み部１８が突板部３２ｄに係合して一体化する。 After the air filter 10 is inserted, the cover member 12 is moved closer to the air filter 10 as shown in FIG. 7, and the air filter 10 is inserted into the hollow portion S of the knob 18 of the cover member 12 as shown in FIG. The protruding plate part 32d is inserted. Thereby, the knob | pick part 18 of the cover member 12 engages and integrates with the protruding plate part 32d.

しかる後、図９に示すように、カバー部材１２を上方へ移動させていきながら、カバー部材１２の前溝１６及び後溝１７に、ケーシング１０１の前側レール１３及び後側レール１４の下端部を挿入する。前溝１６及び後溝１７に前側レール１３及び後側レール１４を挿入していくと、カバー部材１２は、両レール１３，１４によって上方へ案内されるので、作業者は目視することなくカバー部材１２を閉方向に移動させることができる。 Thereafter, as shown in FIG. 9, the lower ends of the front rail 13 and the rear rail 14 of the casing 101 are placed in the front groove 16 and the rear groove 17 of the cover member 12 while moving the cover member 12 upward. insert. When the front rail 13 and the rear rail 14 are inserted into the front groove 16 and the rear groove 17, the cover member 12 is guided upward by the rails 13, 14, so that the operator does not visually observe the cover member. 12 can be moved in the closing direction.

カバー部材１２を上方へ移動させていくと、エアフィルタ１０の第１枠状部材３２がカバー部材１２と一体化しているので、第１濾材３１と共に上方へ移動していく。このとき、図１０に示すように、カバー部材１２の突出部２１の上端部２１ａが第１枠状部材３２の右板部３２ｃの下端部に下方から当接しているので、右板部３２ｃの下端部にも上向きの力を加えることができ、第１枠状部材３２が安定する。尚、第２濾材４１及び第２枠状部材４２は自重により下に留まったままとなるが、第２枠状部材４２をケーシング１０１の内面に係合させるようにしてもよい。 When the cover member 12 is moved upward, the first frame-like member 32 of the air filter 10 is integrated with the cover member 12, and therefore moves upward together with the first filter medium 31. At this time, as shown in FIG. 10, the upper end portion 21a of the protruding portion 21 of the cover member 12 is in contact with the lower end portion of the right plate portion 32c of the first frame-like member 32 from below, so that the right plate portion 32c An upward force can also be applied to the lower end portion, and the first frame member 32 is stabilized. Although the second filter medium 41 and the second frame member 42 remain below due to their own weight, the second frame member 42 may be engaged with the inner surface of the casing 101.

カバー部材１２の動きに連動して第１濾材３１は、第２濾材４１に沿って上方へ移動していく。図２に示すように、カバー部材１２が全閉状態になると、フィルタ挿入孔１１がカバー部材１２で閉塞されるとともに、第１枠状部材３２が上端位置になってケーシング１０１の上壁部１０１ａ内面に近接し、さらに、第１濾材３１が上端位置になり、エアフィルタ１０が展開した状態になる。 In conjunction with the movement of the cover member 12, the first filter medium 31 moves upward along the second filter medium 41. As shown in FIG. 2, when the cover member 12 is fully closed, the filter insertion hole 11 is closed by the cover member 12, and the first frame member 32 is at the upper end position so that the upper wall portion 101 a of the casing 101. Close to the inner surface, the first filter medium 31 is at the upper end position, and the air filter 10 is deployed.

また、カバー部材１２は、その係合爪がケーシング１０１に係合して全閉状態が維持され、これにより、エアフィルタ１０が展開したままになる。 Further, the cover member 12 is maintained in the fully closed state by the engagement claw of the cover member 12 being engaged with the casing 101, whereby the air filter 10 remains unfolded.

以上のようにしてエアフィルタ１０がケーシング１０１に装着される。 The air filter 10 is attached to the casing 101 as described above.

エアフィルタ１０が展開した状態では第１濾材３１の下端部と第２濾材４１の上端部とが前後方向（空気の流通方向）に重なっている。これにより、第１濾材３１と第２濾材４１との間から未濾過の空気が下流側へ洩れるのを抑制することができる。 When the air filter 10 is deployed, the lower end of the first filter medium 31 and the upper end of the second filter medium 41 overlap in the front-rear direction (air flow direction). Thereby, it can suppress that unfiltered air leaks from between the 1st filter medium 31 and the 2nd filter medium 41 to the downstream.

また、古くなったエアフィルタ１０をケーシング１０１から取り出す際には、カバー部材１２のケーシング１０１への係合状態を解除した後、カバー部材１２を下へ移動させる。これにより、第１フィルタ部材３０が下方へ移動していき、エアフィルタ１０が縮小状態になる。そして、カバー部材１２をケーシング１０１から外した後、エアフィルタ１０をフィルタ挿入孔１１から抜き出す。 Further, when the old air filter 10 is taken out from the casing 101, the cover member 12 is moved downward after releasing the engagement state of the cover member 12 with the casing 101. Thereby, the 1st filter member 30 moves below, and the air filter 10 will be in a contracted state. Then, after removing the cover member 12 from the casing 101, the air filter 10 is extracted from the filter insertion hole 11.

以上説明したように、この実施形態によれば、エアフィルタ１０が第１及び第２フィルタ部材３０，４０を備えており、第１フィルタ部材３０の第１濾材３１を第２フィルタ部材４０の第２濾材４１に厚み方向に重ね合わせた状態でスライド可能にしたので、エアフィルタ１０をフィルタ挿入孔１１に挿入する場合に、第１及び第２濾材３１，４１に変形や損傷を与えることなく、しかも、作業性を良好にすることができる。 As described above, according to this embodiment, the air filter 10 includes the first and second filter members 30 and 40, and the first filter medium 31 of the first filter member 30 is the second filter member 40. Since the air filter 10 is inserted into the filter insertion hole 11 without being deformed or damaged, the two filter media 41 can be slid in a state of being overlapped in the thickness direction. In addition, workability can be improved.

また、第１フィルタ部材３０の第１濾材３１のプリーツ形状と、第２フィルタ部材４０の第２濾材４１のプリーツ形状とを略一致させ、第１濾材３１を、第２濾材４１に対して折り目の延びる上下方向にスライド可能に重ね合わせたので、第１濾材３１を上下方向にスライドさせる作業を確実に、かつ、容易に行うことができ、作業性をより一層良好にできる。 In addition, the pleat shape of the first filter medium 31 of the first filter member 30 and the pleat shape of the second filter medium 41 of the second filter member 40 are substantially matched, and the first filter medium 31 is folded with respect to the second filter medium 41. Since the first filter medium 31 is slidably overlapped in the up-down direction in which the first filter medium 31 extends, the operation of sliding the first filter medium 31 in the up-down direction can be performed reliably and easily, and the workability can be further improved.

また、フィルタ挿入孔１１を開閉するカバー部材１２を用いて第１フィルタ部材３０をスライドさせることができるので、作業性をより一層良好にできる。 Moreover, since the 1st filter member 30 can be slid using the cover member 12 which opens and closes the filter insertion hole 11, workability | operativity can be improved further.

また、カバー部材１２をフィルタ挿入孔１１の開閉方向に案内するための前側及び後側レール１３，１４を設け、これらレール１３，１４の案内方向を第１濾材３１のスライド方向としたので、カバー部材１２の開閉動作に連動させて第１濾材３１をスライドさせることができる。 Further, since the front and rear rails 13 and 14 for guiding the cover member 12 in the opening / closing direction of the filter insertion hole 11 are provided, and the guide direction of the rails 13 and 14 is set as the sliding direction of the first filter medium 31, the cover The first filter medium 31 can be slid in conjunction with the opening / closing operation of the member 12.

尚、この実施形態では、第１濾材３１をカバー部材１２によってスライドさせるようにしているが、これに限らず、作業者が第１フィルタ部材３０を直接持って第１濾材３１をスライドさせるようにしてもよい。この場合、カバー部材１２と第１フィルタ部材３０とを係合させなくてもよい。 In this embodiment, the first filter medium 31 is slid by the cover member 12. However, the present invention is not limited to this, and the operator directly holds the first filter member 30 and slides the first filter medium 31. May be.
