Description

本発明は、自動車等の車両に搭載されたエンジンにおける吸気部に配設されるエアクリーナに関するものである。   The present invention relates to an air cleaner disposed in an intake portion of an engine mounted on a vehicle such as an automobile.

自動車等の車両に搭載されたエンジンは、外部の空気をエンジン内に吸い込んで駆動するため、空気中に浮遊する塵埃や異物を捕集するエアクリーナを備えている。図13および図14は、従来のエアクリーナAC1の一例を示したものである。このエアクリーナAC1は、別体に形成された第1半体10と第2半体20とを、両半体10,20の各々の開口部側を対向させて組合わせることで中空箱体状のクリーナケースB1が形成され、このクリーナケースB1の内部にフィルタ部材Fを収納し得るようになっている(図14)。そして、第1半体10には空気流入口16が形成され、第2半体20には空気流出口26が形成されている。従って、空気流入口16からクリーナケースB1内の第1半体10へ導入された空気は、フィルタ部材Fを通過する際に塵埃や異物が分離され、空気流出口26およびエンジンに連結された吸気ダクトへ送出されるようになっている。   An engine mounted on a vehicle such as an automobile includes an air cleaner that collects dust and foreign matters floating in the air in order to drive outside air into the engine. 13 and 14 show an example of a conventional air cleaner AC1. This air cleaner AC1 has a hollow box-like shape by combining the first half 10 and the second half 20 formed separately, with the opening sides of both halves 10 and 20 facing each other. A cleaner case B1 is formed, and the filter member F can be accommodated in the cleaner case B1 (FIG. 14). An air inlet 16 is formed in the first half 10, and an air outlet 26 is formed in the second half 20. Accordingly, the air introduced from the air inlet 16 into the first half 10 in the cleaner case B1 is separated from dust and foreign matters when passing through the filter member F, and the intake air connected to the air outlet 26 and the engine. It is sent to the duct.

前記フィルタ部材Fは、使用するに従い、捕集された塵埃や異物の捕集量が徐々に増加するので、目詰まりを防止するため定期的な清掃または交換が必要であり、クリーナケースB1は、第1半体10と第2半体20とを分離し得るように構成されている。第1半体10と第2半体20とを分離可能に構成するため、第1半体10は、開口部の外縁に沿って環状に延在する外端部12に第1接合部14を備え、また第2半体20は、前記第1接合部14に整合する第2接合部24を、開口部の外縁に沿って環状に延在する外端部22に備えている。そして、第1接合部14には、開口部の周方向に沿って所要間隔毎に複数のボルト締結孔18が設けられ、また第2接合部24には、各ボルト締結孔18に整合するボルト挿通孔28が設けられている。これによりクリーナボックスBは、第1半体10に第2半体20をセットしたもとで、各ボルト挿通孔28を介して各ボルト締結孔18へボルトGを締結することで、第1半体10と第2半体20とが不用意な分離が不能に組付けられる。   As the filter member F is used, the amount of collected dust and foreign matter gradually increases. Therefore, periodic cleaning or replacement is necessary to prevent clogging. It is comprised so that the 1st half body 10 and the 2nd half body 20 can be isolate | separated. Since the first half 10 and the second half 20 are configured to be separable, the first half 10 has the first joint portion 14 at the outer end portion 12 extending in an annular shape along the outer edge of the opening. The second half 20 includes a second joint 24 that is aligned with the first joint 14 at the outer end 22 that extends in an annular shape along the outer edge of the opening. The first joint portion 14 is provided with a plurality of bolt fastening holes 18 at required intervals along the circumferential direction of the opening, and the second joint portion 24 has bolts aligned with the bolt fastening holes 18. An insertion hole 28 is provided. As a result, the cleaner box B is fastened with the bolts G to the respective bolt fastening holes 18 via the respective bolt insertion holes 28 with the second half 20 set on the first half 10. The body 10 and the second half 20 are assembled such that careless separation is impossible.

また、エアクリーナAC1は、第1半体10の第1接合部14と第2半体20の第2接合部24との間から外部空気がクリーナケースB1内へ侵入するのを防止する必要がある。このため、図14に示すように、第1接合部14には、開口部の周方向へ延在する突部19が突設され、第2接合部24には、開口部の周方向へ延在して突部19が突入して嵌合する凹部29が形成されている。従って、第1半体10と第2半体20とをボルトGの締結により組付けた際には、凹部29と突部19とが嵌合して密着することで、クリーナケースB1のシール状態が形成されるよう構成されている。このようなエアクリーナは、特許文献1に開示されている。   The air cleaner AC1 needs to prevent external air from entering the cleaner case B1 from between the first joint portion 14 of the first half body 10 and the second joint portion 24 of the second half body 20. . Therefore, as shown in FIG. 14, the first joint portion 14 is provided with a protrusion 19 extending in the circumferential direction of the opening, and the second joint portion 24 is extended in the circumferential direction of the opening. A recess 29 is formed in which the protrusion 19 enters and fits. Therefore, when the first half 10 and the second half 20 are assembled by fastening the bolt G, the recess 29 and the protrusion 19 are fitted and brought into close contact with each other, so that the cleaner case B1 is sealed. Is formed. Such an air cleaner is disclosed in Patent Document 1.

なお、第1半体10の第1接合部14または第2半体20の第2接合部24に、柔軟性を有するスポンジまたはゴム等を材料とするシール部材を装着して、第1半体10と第2半体20とを組付けた際に該シール部材でシール状態を形成する形態も広く実施されている。   In addition, a sealing member made of a flexible sponge or rubber or the like is attached to the first joint portion 14 of the first half body 10 or the second joint portion 24 of the second half body 20, so that the first half body A form in which a sealing state is formed by the sealing member when the 10 and the second half 20 are assembled is also widely implemented.

特開2005−256635号公報JP 2005-256635 A

ところで、図13に示した従来のエアクリーナAC1における第1半体10および第2半体20は、成形時に発生した成形歪みや、該エアクリーナAC1を配設した部位における部周囲の温度や湿度等の使用環境により変形するおそれがある。また、第1接合部14に一体形成した前記突部19は、突出幅が変化するような弾性変形が不可能であり、第2接合部24に一体形成した凹部29は、開口幅が変化するような弾性変形が不可能に形成されている。このため、第1半体10と第2半体20との組付け時に両半体10,20の両方または何れか一方が変形していると、突部19と凹部29とが、両半体10,20の組付け方向で対向しないので嵌合不良によりシール状態が適切に形成されない問題を内在している。また、第1半体10と第2半体20との組付け時には突部19と凹部29とが適切に当接してシール状態が形成されていても、使用途中に第1半体10または第2半体20が変形すると突部19と凹部29との間に隙間が形成されることもあり得る。   By the way, the first half 10 and the second half 20 in the conventional air cleaner AC1 shown in FIG. 13 have molding distortion generated during molding, temperature and humidity around the part where the air cleaner AC1 is provided, and the like. There is a risk of deformation depending on the usage environment. Further, the protrusion 19 formed integrally with the first joint 14 cannot be elastically deformed so that the protrusion width changes, and the opening 29 of the recess 29 formed integrally with the second joint 24 changes. Such elastic deformation is impossible. Therefore, when the first half 10 and the second half 20 are assembled, if both or either one of the half halves 10 and 20 is deformed, the protrusion 19 and the recess 29 are formed into both halves. There is a problem in that the seal state is not properly formed due to poor fitting because it is not opposed in the assembly direction of 10,20. In addition, when the first half 10 and the second half 20 are assembled, the first half 10 or the second half 20 can be used in the middle of use even if the protrusion 19 and the recess 29 are in proper contact with each other to form a sealed state. If the half body 20 is deformed, a gap may be formed between the protrusion 19 and the recess 29.

一方、第1半体10と第2半体20との組付け時に複数のボルトBを締結する作業が伴い、また第2半体20を第1半体10から取外す時にも各ボルトBを緩める作業が必要となるから、フィルタ部材Fの脱着作業が面倒で煩雑になっていた。また、ボルトBを回転させる工具がなければ、第1半体10と第2半体20との分離ができない課題もある。   On the other hand, when the first half 10 and the second half 20 are assembled, a plurality of bolts B are fastened, and each bolt B is also loosened when the second half 20 is removed from the first half 10. Since the work is required, the work of detaching the filter member F is troublesome and complicated. Further, there is a problem that the first half 10 and the second half 20 cannot be separated without a tool for rotating the bolt B.

そこで本発明では、第1半体と第2半体との接合部分を長期間に亘ってシールされた状態に保持すると共に、フィルタ部材の脱着作業の簡易化を図ったエアクリーナを提供することを目的とする。   Therefore, the present invention provides an air cleaner that keeps the joined portion of the first half and the second half sealed for a long period of time and simplifies the removal and attachment of the filter member. Objective.

第1半体30の上端部32の外側には、図1および図2に示すように、上端部32から外方へ延出して該上端部32の全周に亘って延在し、第1開口部34を環状に囲繞する第1接合部50が形成されている。この第1接合部50は、上端部32よりも第2半体40側(上方)へ突出し、上下方向に一致する短手方向での断面形状が略逆U字形をなす軒樋状の環状突条部52を備えている。この環状突条部52は、図1〜図4に示すように、上端部32の外側に隣接する部位から垂直に立ち上がった第1内側部(一方の側壁部)52Aと、第1内側部52Aの上部から上方へ突出しながら外方へ約180度に湾曲した第1湾曲部52Bと、第1湾曲部52Bの外端から下方へ垂直に垂下した第1外側部(他方の側壁部)52Cとから構成されている。そして、第1内側部52Aの外面は、上端部32に沿って延在する環状の第1内側シール面54となっていると共に、第1外側部52Cの外面が、第1内側シール面54の水平方向外側において該第1内側シール面54と相似状に延在する環状の第1外側シール面56となっている。   As shown in FIG. 1 and FIG. 2, the first half 30 has an outer end extending outward from the upper end 32 and extending over the entire circumference of the upper end 32, as shown in FIGS. 1 and 2. A first joint 50 that surrounds the opening 34 in an annular shape is formed. The first joint 50 protrudes from the upper end 32 toward the second half 40 (upward), and has an eaves-like annular protrusion whose cross-sectional shape in the short direction that coincides with the vertical direction forms a substantially inverted U shape. A strip 52 is provided. As shown in FIGS. 1 to 4, the annular protrusion 52 includes a first inner portion (one side wall portion) 52 </ b> A that rises vertically from a portion adjacent to the outside of the upper end portion 32, and a first inner portion 52 </ b> A.

An annular first outer seal surface 56 extends in a similar manner to the first inner seal surface 54 on the outer side in the horizontal direction.

第1内側部52A、第1湾曲部52Bおよび第1外側部52Cは、何れも略同じ厚みに形成されており、環状突条部52の内側(裏側)には空間58が形成されている。従って環状突条部52は、第1湾曲部52Bが弾性変形することで、上下方向に一致する短手方向において、第1外側部52Cが第1内側部52Aに対して近接・離間変位が可能となっている。すなわち環状突条部52は、外力が付与されない状態(自然状態)において、第1内側シール面54と第1外側シール面56とは垂直かつ平行に延在しており、第1内側シール面54と第1外側シール面56との水平方向の突出幅(第1内側部52Aの外面と第1外側部52Cの外面との間隔)はW1となっている(図5)。   The first inner portion 52A, the first curved portion 52B, and the first outer portion 52C are all formed to have substantially the same thickness, and a space 58 is formed on the inner side (back side) of the annular protrusion 52. Accordingly, the annular protrusion 52 can be moved closer to and away from the first inner portion 52A in the short direction that coincides with the vertical direction by elastically deforming the first curved portion 52B. It has become. That is, in the annular protrusion 52, in a state where no external force is applied (natural state), the first inner seal surface 54 and the first outer seal surface 56 extend vertically and in parallel, and the first inner seal surface 54 The horizontal protruding width between the first outer seal surface 56 and the first outer seal surface 56 (the distance between the outer surface of the first inner portion 52A and the outer surface of the first outer portion 52C) is W1 (FIG. 5).

第2半体40は、図1および図2に示すように、インジェクション成形された合成樹脂製の一体成形部材であり、下方に開口する逆バケット形状をなし、下方の第2開口部44を形成する下端部42が、前記第1半体30の上端部32と整合する略五角形をなしている。そして第2半体40は、図4に示すように、下端部42の周方向へ延在する垂直の壁部の内側に、垂直に延在して下端部42(第2開口部44)に下端が位置すると共に内側へ突出した板状のリブ(当接部)48が、該下端部42の周方向へ所要間隔毎に複数個設けられている。各リブ48は、第1半体30に第2半体40を組付けた際に、第1半体30の設置部38にセットしたフィルタ部材Fの上面に当接するようになっている。従って、設置部38にセットしたフィルタ部材Fは、第1半体30と第2半体40との組付け方向において、段部36および各リブ48とにより上下から挟持されて上下方向への移動が規制される。また第2半体40は、図示しないエンジンの吸気部に接続された吸気ダクトに連結される空気流出口入口46を備えている。第2半体40を形成する合成樹脂としては、第1半体30と同じくポリプロピレン、ABS、フェノール樹脂、ポリカーボネート、高密度ポリエチレン等で、JIS K7202に基づくロックウェル硬さがHRR70〜HRR100のものが好適に実施される。   As shown in FIGS. 1 and 2, the second half 40 is an integrally molded member made of synthetic resin that is injection-molded, has an inverted bucket shape that opens downward, and forms a lower second opening 44. The lower end portion 42 to be formed has a substantially pentagonal shape aligned with the upper end portion 32 of the first half 30. Then, as shown in FIG. 4, the second half 40 extends vertically inside the vertical wall portion extending in the circumferential direction of the lower end portion 42 and extends into the lower end portion 42 (second opening 44). A plurality of plate-like ribs (abutting portions) 48 that are located at the lower end and protrude inward are provided in the circumferential direction of the lower end portion 42 at every required interval. Each rib 48 comes into contact with the upper surface of the filter member F set on the installation portion 38 of the first half 30 when the second half 40 is assembled to the first half 30. Therefore, the filter member F set in the installation portion 38 is sandwiched from above and below by the step portion 36 and each rib 48 in the assembling direction of the first half body 30 and the second half body 40 and moves in the vertical direction. Is regulated. The second half 40 also includes an air outlet inlet 46 connected to an intake duct connected to an intake portion of an engine (not shown).

It is preferably implemented.

なお、第1半体30および第2半体40の形成に使用される合成樹脂の硬さがHRR70より小さくなると、エアクリーナACの使用期間中において、第1接合部50と第2接合部60とが変形して両部の嵌合が外れたり、後述する係止手段70が変形して係止が外れるおそれがある。また、硬さがHRR100より大きくなると、第1接合部50と第2接合部60とが弾性変形し難いので両部の嵌合が困難になったり、係止手段70が弾性変形し難いので係止が困難になったり該係止手段70が破損するおそれがある。   When the hardness of the synthetic resin used for forming the first half 30 and the second half 40 is smaller than the HRR 70, the first joint 50 and the second joint 60 are used during the period of use of the air cleaner AC. May be deformed and the fitting of both parts may be released, or the locking means 70 described later may be deformed and unlocked. Also, if the hardness is greater than HRR 100, the first joint 50 and the second joint 60 are difficult to be elastically deformed, making it difficult to fit both parts, and the locking means 70 is difficult to elastically deform. It may be difficult to stop or the locking means 70 may be damaged.

第2半体40の下端部42の外側には、図1および図2に示すように、下端部42から外方へ延出して該下端部42の全周に亘って延在し、第2開口部44を環状に囲繞する第2接合部60が形成されている。この第2接合部60は、下端部42よりも第2半体40側(上方)へ陥凹し、上下方向に一致する短手方向での断面形状が略逆U字形をなす軒樋状の環状凹溝部62を備えている。この環状凹溝部62は、図1〜図4に示すように、下端部42の外側に隣接する部位から垂直に立ち上がった第2内側部(一方の側壁部)62Aと、第2内側部62Aの上部から上方へ突出しながら外方へ約180度に湾曲した第2湾曲部62Bと、第2湾曲部62Bの外端から下方へ垂直に垂下した第2外側部(他方の側壁部)62Cとから構成されている。そして、第2内側部62Aの内面は、下端部42に沿って延在する環状の第2内側シール面64となっていると共に、第2外側部62Cの内面が、第2内側シール面64の水平方向外側において該第2内側シール面64と相似状に延在する環状の第2外側シール面66となっている。なお、第1接合部50と第2接合部60との嵌合時には、第2内側シール面64は第1内側シール面54と面接触し、第2外側シール面66は第1外側シール面56と面接触するようになっている。   As shown in FIGS. 1 and 2, the second half 40 extends outward from the lower end 42 and extends over the entire circumference of the lower end 42, as shown in FIGS. 1 and 2. A second joint 60 that surrounds the opening 44 in an annular shape is formed. The second joint portion 60 is recessed toward the second half 40 side (upward) from the lower end portion 42, and has an eaves-like shape in which the cross-sectional shape in the short direction that coincides with the vertical direction forms a substantially inverted U shape. An annular concave groove 62 is provided.

From a second curved portion 62B that is curved outward by about 180 degrees while projecting upward from the upper portion, and a second outer portion (the other side wall portion) 62C that hangs vertically downward from the outer end of the second curved portion 62B. It is configured. The inner surface of the second inner portion 62 </ b> A is an annular second inner seal surface 64 extending along the lower end portion 42, and the inner surface of the second outer portion 62 </ b> C is the second inner seal surface 64. An annular second outer seal surface 66 extending in a similar manner to the second inner seal surface 64 on the outer side in the horizontal direction. When the first joint 50 and the second joint 60 are fitted, the second inner seal surface 64 is in surface contact with the first inner seal surface 54, and the second outer seal surface 66 is the first outer seal surface 56. And come into surface contact.

第2内側部62Aは、実質的に第2半体40の壁面と一体化しているが、第2湾曲部62Bおよび第2外側部62Cは、何れも略同じ厚みに形成されている。従って環状凹溝部62は、第2湾曲部62Bが弾性変形することで、上下方向に一致する短手方向において、第2外側部62Cが第2内側部62Aに対して近接・離間変位が可能となっている。すなわち環状凹溝部62は、外力が付与されない状態(自然状態)において、第2内側シール面64と第2外側シール面66との水平方向の開口幅(第2内側部62Aの内面と第2外側部62Cの内面との間隔)はW2となっている(図5)。また、第2内側シール面64と第2外側シール面66とは、外力が付与されない状態において、垂直かつ平行になっている。   The second inner portion 62A is substantially integrated with the wall surface of the second half 40, but the second curved portion 62B and the second outer portion 62C are both formed to have substantially the same thickness. Therefore, the annular groove portion 62 is configured such that the second curved portion 62B is elastically deformed so that the second outer portion 62C can be moved toward and away from the second inner portion 62A in the short direction that coincides with the vertical direction. It has become. In other words, the annular groove portion 62 has a horizontal opening width between the second inner seal surface 64 and the second outer seal surface 66 (the inner surface and the second outer surface of the second inner portion 62A) when no external force is applied (natural state). The interval between the portion 62C and the inner surface is W2 (FIG. 5). The second inner seal surface 64 and the second outer seal surface 66 are vertical and parallel when no external force is applied.

すなわち、第1半体30に設けた第1接合部50は、第2半体40側へ環状に突出しており、第2半体40に設けた第2接合部60は、第1半体30から離間する側へ環状に陥凹していると共に該第1半体30側へ環状に開口している。これにより、第1接合部50の環状突条部52を第2接合部60の環状凹溝部62へ突入することで、第1半体30と第2半体40とが組付けられるように構成されている。なお、第1接合部50の第1内側部52A、第1湾曲部52Bおよび第1外側部52Cの厚みと、第2接合部60の第2湾曲部62Bおよび第2外側部62Cの厚みは、第1接合部50と第2接合部60との弾力変形を伴った適切な嵌合を考慮すると1.5〜3.5mmが好ましい。   That is, the 1st junction part 50 provided in the 1st half body 30 protrudes cyclically | annularly to the 2nd half body 40 side, and the 2nd junction part 60 provided in the 2nd half body 40 is 1st half body 30. And is opened in an annular shape toward the first half 30 side.

第1係止部72と第2係止部74とは、第1接合部50の環状突縁部52を第2接合部60の環状凹溝部62の内側に嵌合させると(図6(a))、第2係止部74の係止面部74Dが第1係止部72の係止面部72Cより第2半体40側に位置するように設定されている。そして、第1係止部72と第2係止部74との少なくとも一方の係止部を他方の係止部へ近づけるように変位させることで、第1係止部72の係止面部72Cと第2係止部74の係止面部74Dとが、第1接合部50と第2接合部60との嵌合方向で互いに対向して引掛かり、第1係止部72と第2係止部74とは互いに引き合いながら係止されるようになっている。従って、第2係止部74に係止した第1係止部72により、第1接合部50の環状突条部52は、突出幅がW1より大きくなるように付勢されて、第2接合部60の環状凹溝部62を内側から押し広げるように変形し得る。また、第1係止部72に係止した第2係止部74により、第2接合部60の環状凹溝部62は、開口幅がW2より小さくなるように付勢されて、第1接合部50の環状突条部52を外側から締め付けるように変形する。   The first locking portion 72 and the second locking portion 74 are configured such that the annular protrusion 52 of the first joint 50 is fitted inside the annular groove 62 of the second joint 60 (FIG. 6A). )), The locking surface portion 74D of the second locking portion 74 is set to be positioned closer to the second half 40 side than the locking surface portion 72C of the first locking portion 72. Then, by displacing at least one of the first locking portion 72 and the second locking portion 74 so as to approach the other locking portion, the locking surface portion 72C of the first locking portion 72 The locking surface portion 74D of the second locking portion 74 is hooked opposite to each other in the fitting direction of the first bonding portion 50 and the second bonding portion 60, and the first locking portion 72 and the second locking portion. 74 is locked while attracting each other. Accordingly, the first locking portion 72 locked to the second locking portion 74 urges the annular protrusion 52 of the first bonding portion 50 so that the protruding width is larger than W1. The annular groove portion 62 of the portion 60 can be deformed so as to be expanded from the inside. Further, by the second locking portion 74 locked to the first locking portion 72, the annular groove portion 62 of the second joint portion 60 is urged so that the opening width becomes smaller than W2, and the first joint portion The 50 annular protrusions 52 are deformed so as to be tightened from the outside.

前記係止解除片80は、図1〜図5に示すように、第2係止部74の横基板部74Aの先端において、縦係止板部74Bの延出方向と反対となる上方へ延出するように該縦係止板部74Bに一体的に形成されている。すなわち、係止解除片80と縦係止板部74Bとは、横基板部74Aに連設された1枚の平板状を呈している。従って、図7(a)に示すように、係止解除片80の上端近傍を第2半体40の外側から該第2半体40側へ指先で押すと、該係止解除片80および縦係止板部74Bが横基板部74Aを中心としてシーソー状に姿勢変位するようになっている。すなわち、係止解除片80を第2半体40側へ指先で押すことで、第2係止部74の縦係止板部74Bが第1係止部72の横係止板部72Bから離間するように変位して第1係止部72と第2係止部74との係止が解除され、これにより第2半体40を第1半体30から取り外すことが可能となっている(図7(b))。なお、第2係止部74の横基板部74Aと係止解除片80との連設部内側にはリブ82が形成されており、係止解除片80を指先で押した際には、横基板部74Aと係止解除片80との角度が保持されるよう考慮されている。   As shown in FIGS. 1 to 5, the locking release piece 80 extends upward at the tip of the horizontal substrate portion 74 </ b> A of the second locking portion 74, which is opposite to the extending direction of the vertical locking plate portion 74 </ b> B. It is formed integrally with the vertical locking plate 74B so as to protrude. That is, the locking release piece 80 and the vertical locking plate portion 74B have a single flat plate shape that is connected to the horizontal substrate portion 74A. Therefore, as shown in FIG. 7A, when the vicinity of the upper end of the unlocking piece 80 is pushed from the outside of the second half 40 toward the second half 40 with the fingertip, The locking plate 74B is displaced in a seesaw shape around the horizontal substrate 74A. That is, by pushing the locking release piece 80 toward the second half 40 with the fingertip, the vertical locking plate portion 74B of the second locking portion 74 is separated from the horizontal locking plate portion 72B of the first locking portion 72. Thus, the first locking portion 72 and the second locking portion 74 are unlocked so that the second half 40 can be removed from the first half 30 ( FIG. 7 (b)). A rib 82 is formed on the inner side of the connecting portion between the horizontal substrate portion 74A of the second locking portion 74 and the locking release piece 80. When the locking release piece 80 is pushed with a fingertip, It is considered that the angle between the board portion 74A and the locking release piece 80 is maintained.

フィルタ部材Fは、図2および図4に示すように、不織布やスポンジ等からなる濾材90と、該濾材90を保持する枠体92とからなる。枠体92は、第1半体30に設けた前記設置部38の内壁面形状に合わせた外形形状に形成され、該設置部38にセットした際に、第1半体30と第2半体40との組付け方向と交差する方向へのがたつきが規制される。また枠体92は、上面および下面に開口部を備えており、濾材90の下面側から上面側への空気の通過を許容する。なお、濾材90や枠体92の詳細は本願の要旨ではないので、ここでは説明を省略する。   As shown in FIGS. 2 and 4, the filter member F includes a filter medium 90 made of a nonwoven fabric, sponge, or the like, and a frame 92 that holds the filter medium 90. The frame 92 is formed in an outer shape that matches the shape of the inner wall surface of the installation portion 38 provided in the first half 30, and when set in the installation portion 38, the first half 30 and the second half The rattling in the direction intersecting with the assembly direction with 40 is regulated. Further, the frame body 92 has openings on the upper surface and the lower surface, and allows the passage of air from the lower surface side of the filter medium 90 to the upper surface side. The details of the filter medium 90 and the frame body 92 are not the gist of the present application, and thus the description thereof is omitted here.

前述のように構成された実施例のエアクリーナACは、第1半体30の設置部38にフィルタ部材Fを予めセットしたもとで、第1半体30の上端部32および第2半体40の下端部42を対向させて第1接合部50と第2接合部60とを整合させた姿勢で、両半体30,40を互いに近接する方向に押付けることで、フィルタケースBが組立てられる。このとき、前記条件1に基づき、第1接合部50の環状突条部52では、第1外側部52Cが第1内側部52Aに近接するように弾性変形し、第2接合部60の環状凹溝部62では、第2外側部62Cが第2内側部62Aから離間するように弾性変形して、環状突条部52が環状凹溝部62の内側へ嵌合される(図6(a)参照)。すなわち、第1接合部50の環状突条部52が、その突出幅が適宜小さくなるように弾性変形し、また第2接合部60の環状凹溝部62が、その開口幅が大きくなるように弾性変形することで、第1接合部50と第2接合部60との嵌合が小さな力でスムーズになされる。   The air cleaner AC of the embodiment configured as described above has the upper end portion 32 and the second half 40 of the first half 30 with the filter member F set in advance in the installation portion 38 of the first half 30. The filter case B is assembled by pressing the half halves 30 and 40 in a direction close to each other in a posture in which the first joint portion 50 and the second joint portion 60 are aligned with the lower end portions 42 thereof facing each other. . At this time, based on the condition 1, the annular protrusion 52 of the first joint 50 is elastically deformed so that the first outer portion 52C is close to the first inner portion 52A, and the annular recess of the second joint 60 is formed. In the groove portion 62, the second outer portion 62C is elastically deformed so as to be separated from the second inner portion 62A, and the annular protrusion 52 is fitted inside the annular groove portion 62 (see FIG. 6A). . That is, the annular protrusion 52 of the first joint 50 is elastically deformed so that the protrusion width is appropriately reduced, and the annular groove 62 of the second joint 60 is elastic so that the opening width thereof is increased. By deform | transforming, fitting with the 1st junction part 50 and the 2nd junction part 60 is made smoothly with small force.

次いで、図6(b)に示すように、第1半体30に対して第2半体40が規定の位置まで近接して、第2半体40の各リブ48がフィルタ部材Fの上面に当接したら、第1係止部72の横係止板部72Bを上方へ変位させると共に、第2係止部74の縦係止板部74Bを第1半体30側へ変位させることで、両係止部72,74の各係止面部72C,74Dが当接して横係止板部72Bと縦係止板部74Bとが係止される。これにより、第1係止部72と第2係止部74とは互いに引き合う関係で係止され、第1接合部50の環状突条部52が第2接合部60の環状凹溝部62を内側から押し広げるように弾性変形し、第2接合部60の環状凹溝部62が第1接合部50の環状突条部52を外側から締め付けるように弾性変形する。これにより、第1内側シール面54と第2内側シール面64とが各開口部34,44を囲繞するように環状に面接触して第1シール部L1が形成され、第1外側シール面56と第2外側シール面66とが環状に面接触して、第1シール部L1を囲繞する第2シール部L2が形成される。従って、第1半体30と第2半体40との接合部には、第1シール部L1と第2シール部L2とが内外2重に形成され、エアクリーナACのシール性が向上している。   Next, as shown in FIG. 6 (b), the second half 40 is close to the prescribed position with respect to the first half 30, and each rib 48 of the second half 40 is placed on the upper surface of the filter member F. When abutting, the lateral locking plate 72B of the first locking portion 72 is displaced upward, and the vertical locking plate 74B of the second locking portion 74 is displaced to the first half 30 side, The locking surface portions 72C and 74D of the both locking portions 72 and 74 come into contact with each other, and the horizontal locking plate portion 72B and the vertical locking plate portion 74B are locked. As a result, the first locking portion 72 and the second locking portion 74 are locked in a mutually attracting relationship, and the annular ridge portion 52 of the first joint portion 50 moves the annular groove portion 62 of the second joint portion 60 inside. The annular groove portion 62 of the second joint portion 60 is elastically deformed so as to tighten the annular protrusion 52 of the first joint portion 50 from the outside. As a result, the first inner seal surface 54 and the second inner seal surface 64 are in annular contact with each other so as to surround the openings 34 and 44, thereby forming the first seal portion L 1, and the first outer seal surface 56. And the second outer seal surface 66 are in annular contact with each other to form a second seal portion L2 surrounding the first seal portion L1. Therefore, the first seal portion L1 and the second seal portion L2 are formed in the inner and outer doubles at the joint portion between the first half 30 and the second half 40, and the sealing performance of the air cleaner AC is improved. .

更に、前述した如く、第1湾曲部52Bの内面の外面曲率半径R1が第2湾曲部62Bの内面曲率半径R2より大きく設定されているので、図4に示すように、第1湾曲部52Bと第2湾曲部62Bとの間に適宜の隙間Mが画成され、第1湾曲部52Bと第2湾曲部62Bとが接触していない。更にまた、前記条件2により、第1半体30と第2半体40とを適切に組付けた状態においては、第1半体30の上端部32と第2半体40の下端部42とは当接していないので、第1接合部50の環状突条部52が、第2接合部60の環状凹溝部62に対して奥まで入り込んで深く嵌合している。   Further, as described above, since the outer surface curvature radius R1 of the inner surface of the first curved portion 52B is set larger than the inner surface radius of curvature R2 of the second curved portion 62B, as shown in FIG. An appropriate gap M is defined between the second bending portion 62B and the first bending portion 52B and the second bending portion 62B are not in contact with each other. Furthermore, when the first half 30 and the second half 40 are appropriately assembled according to the condition 2, the upper end 32 of the first half 30 and the lower end 42 of the second half 40 are Are not in contact with each other, and the annular ridge portion 52 of the first joint portion 50 is deeply fitted into the annular groove portion 62 of the second joint portion 60.

なお、第1半体30と第2半体40との組付けは、係止解除片80を第2半体40側へ指先で押して、第2係止部74を傾動変位させながら行なってもよい。このように第2係止部74を変位させれば、該第2係止部74の縦係止板部74Bと第1係止部72の横係止板部72Bとが当接しない状態で第1半体30と第2半体40との組付けがなされるから、該第1半体30と第2半体40との組付けを軽い力で行なうことができる。また、第1半体30と第2半体40とを組付けは、係止解除片80の上端を指先で下方へ押しながら行なってもよい。このように係止解除片80を下方へ押すと、第1係止部72の横係止板部72Bの先端に第2係止部74の係止爪部74Cとが当接する際に、押し下げる力によって係止解除片80が第2半体40側へ指先で押した際と同様に第2係止部74が傾動変位するから、第1半体30と第2半体40との組付けが可能である。   The first half 30 and the second half 40 may be assembled while the second release portion 74 is tilted and displaced by pushing the locking release piece 80 toward the second half 40 with a fingertip. Good. If the second locking portion 74 is displaced in this manner, the vertical locking plate portion 74B of the second locking portion 74 and the horizontal locking plate portion 72B of the first locking portion 72 are not in contact with each other. Since the first half 30 and the second half 40 are assembled, the first half 30 and the second half 40 can be assembled with a light force. The first half 30 and the second half 40 may be assembled while pushing the upper end of the locking release piece 80 downward with a fingertip. When the locking release piece 80 is pushed downward in this way, it is pushed down when the locking claw portion 74C of the second locking portion 74 comes into contact with the tip of the lateral locking plate portion 72B of the first locking portion 72. Since the second locking portion 74 is tilted and displaced in the same manner as when the locking release piece 80 is pushed by the fingertip toward the second half 40 by force, the first half 30 and the second half 40 are assembled. Is possible.

また、フィルタ部材Fの清掃または交換が必要になった場合には、各係止手段70に設けた前記係止解除片80を指先で押し操作して第1係止部72と第2係止部74との係止を解除させたもとで第2半体40を上方へ移動することで、該第2半体40を第1半体30から取り外す。これにより第1半体30の第1開口部34が外部へ露出され、設置部38に対するフィルタ部材Fの脱着が可能となる。   Further, when the filter member F needs to be cleaned or replaced, the first locking portion 72 and the second locking portion are operated by pushing the locking release pieces 80 provided on the locking means 70 with the fingertips. The second half 40 is removed from the first half 30 by moving the second half 40 upward while releasing the locking with the portion 74. As a result, the first opening 34 of the first half 30 is exposed to the outside, and the filter member F can be attached to and detached from the installation portion 38.

従って、実施例のエアクリーナACでは、次のような作用効果を奏する。
(1)第1接合部50の環状突条部52を第2接合部60の環状凹溝部62に嵌合させることで、弾性変形した環状突条部52が環状凹溝部62を内側から押し広げるように付勢し、弾性変形した環状凹溝部62が環状突条部52を外側から締め付けるように付勢するので、第1接合部50と第2接合部60とが弾力的に当接して互いに押付け合うようになり、クリーナケースBの接合部分のシール性が向上する。そして、第1半体30または第2半体40が成形歪みが発生したり、該第1半体30または第2半体40が使用環境により使用途中に変形しても、第1接合部50と第2接合部60とのシール状態を維持することができる。
(2)第1接合部50の環状突条部52を第2接合部60の環状凹溝部62に嵌合させた状態で、更に第1係止部72と第2係止部74とが係止することで、第1接合部50および第2接合部60とのシール状態を長期間に亘って維持でき、使用途中に第1接合部50と第2接合部60との間に隙間が形成されるのを防止し得る。
(3)第1接合部50と第2接合部60とは、第1シール部L1および該第1シール部L1を外側から囲繞する第2シール部L2により内外2重に密着してシールされるので、第1半体30と第2半体40との接合部から塵埃や異物を有する外部空気がクリーナケースB内へ侵入することを防止し得る。
(4)第1係止部72の係止面部72Cと第2係止部74の係止面部74Dとが、第1接合部50と第2接合部60との嵌合方向(第1半体30と第2半体40の組付け方向)で対向して引掛かっているので、両接合部50,60の嵌合が解除され難く、使用途中に第1半体30と第2半体40との連結が不用意に解除されるのを防止し得る。
(5)係止解除片80を指先操作することで、別途の工具を使用することなく第2半体40を第1半体30から取り外すことができ、フィルタ部材Fの取外し作業の簡易化を図り得る。なお、第1半体30に第2半体40を組付ける際にも工具を使用する必要がないので、フィルタ部材Fの取付け作業も煩雑にならない。

By stopping, the sealing state between the first joint 50 and the second joint 60 can be maintained over a long period of time, and a gap is formed between the first joint 50 and the second joint 60 during use. Can be prevented.
(3) The first joint portion 50 and the second joint portion 60 are sealed in close contact with the inner and outer layers by the first seal portion L1 and the second seal portion L2 surrounding the first seal portion L1 from the outside. Therefore, it is possible to prevent the outside air having dust and foreign matter from entering the cleaner case B from the joint between the first half 30 and the second half 40.
(4) The engaging surface portion 72C of the first engaging portion 72 and the engaging surface portion 74D of the second engaging portion 74 are fitted in the fitting direction (first half body) of the first joint portion 50 and the second joint portion 60. 30 and the second half 40 in the opposite direction), the joints 50 and 60 are difficult to be released, and the first half 30 and the second half 40 Can be prevented from being inadvertently released.
(5) The second half 40 can be removed from the first half 30 without using a separate tool by operating the locking release piece 80 with a fingertip, and the removal work of the filter member F can be simplified. It can be planned. In addition, since it is not necessary to use a tool also when assembling the 2nd half body 40 to the 1st half body 30, the installation operation | work of the filter member F does not become complicated.
(6) When the first half 30 and the second half 40 are assembled, the upper end 32 connected to the first joint 50 of the first half 30 and the second half 40 of the second half 40 Since the lower end portion 42 connected to the joint portion 60 does not come into contact, the annular ridge portion 52 of the first joint portion 50 comes into the depth of the annular groove portion 62 of the second joint portion 60, and the first The 1 junction part 50 and the 2nd junction part 60 fit appropriately. And even if the 1st half 30 or the 2nd half 40 deform | transforms suitably, while fitting with the 1st junction part 50 and the 2nd junction part 60 is maintained, the 1st half 30 and the 2nd half It is possible to prevent the first joint 50 or the second joint 60 from being damaged by the deformation of the body 40. Moreover, the filter member F set in the installation part 38 can be appropriately held in the assembly direction of the first half 30 and the second half 40.
(7) The seal between the first joint 50 and the second joint 60 is the first joint 50 formed integrally with the first half 30 and the second joint integrally formed with the second half 40. Since it is made by elastic deformation with the portion 60 and there is no need to prepare and attach a separate seal member, the manufacturing cost of the air cleaner AC does not increase.
(8) Since the space 58 is formed between the first curved portion 52B of the annular ridge portion 52 and the second curved portion 62B of the annular concave groove portion 62, the first is adapted to the deformation of the second joint portion 60. The joint portion 50 can be deformed, and even if the first joint portion 50 or the second joint portion 60 is individually deformed, the sealing performance between the first seal portion L1 and the second seal portion L2 is prevented from being deteriorated. Can do.
(9) By fitting the annular protrusion 52 of the first joint 50 into the annular groove 62 of the second joint 60, the mutual positioning of the first half 30 and the second half 40 is illustrated. Thus, the first half 30 and the second half 40 are unlikely to be misaligned. Further, when the first locking portion 72 and the second locking portion 74 are locked, the locking can be confirmed by a click feeling that the claw catches, and the first half 30 and the second half 40 are securely connected. be able to.

(Example of change)
The air cleaner AC of the present application is not limited to the form of the above-described embodiment, and various modifications are possible. (1) The first joint portion 50 and the second joint portion 60 are limited to those having the shapes shown in the embodiments. For example, a form as shown in FIGS. 8 and 9 may be used. In the form shown in FIG. 8, the first joint portion 50 has an eaves-like shape in which the cross-sectional shape in the short direction that coincides with the vertical direction is a so-called inverted angle U-shape (the example is “reverse-round U-shape”). The second joint portion 60 includes an eaves-like annular groove portion 62 in which the cross-sectional shape in the short direction that coincides with the vertical direction forms an inverted U-shape. Even in such a shape, the first joint portion 50 is provided with the first inner seal surface 54 and the first outer seal surface 56 similar to the embodiment, and the second joint portion 60 has the second inner seal surface. 64 and the second outer seal surface 66 are provided, and the first seal portion L1 and the second seal portion L2 are formed by locking the locking means 70. In the form shown in FIG. 9, the first joint portion 50 includes an eaves-like annular ridge portion 52 whose cross-sectional shape in a short direction that coincides with the vertical direction forms a so-called reverse base shape, and the second joint portion 60 is provided with an eaves-like annular groove portion 62 whose cross-sectional shape in the short direction that coincides with the up-down direction forms a reverse inverted U-shape. Even in such a shape, the first joint portion 50 is provided with the first inner seal surface 54 and the first outer seal surface 56 similar to the embodiment, and the second joint portion 60 has the second inner seal surface. 64 and a second outer seal surface 66 are provided, and the first seal portion L1 and the second seal portion L2 are formed by locking the locking means 70.

(2)係止手段70は、実施例に示した形状のものに限定されず、例えば図10〜図12に示すような形態であってもよい。図10は、第2係止部74の縦係止板部74Bおよび係止解除片80に亘り、薄い鋼板等からなるプレート状の補強体100をインサートしたものである。このような補強体100を第2係止部74にインサートすることで、係止解除片80を押した際に、縦係止板部74Bに対して係止解除片80が撓んだり折曲することがなく、係止解除片80の変位により縦係止板部74を確実に傾動変位させ得る。 (2) The locking means 70 is not limited to the shape shown in the embodiment, and may have a form as shown in FIGS. FIG. 10 shows an example in which a plate-like reinforcing body 100 made of a thin steel plate or the like is inserted across the vertical locking plate portion 74B and the locking release piece 80 of the second locking portion 74. By inserting such a reinforcing body 100 into the second locking portion 74, when the locking release piece 80 is pushed, the locking release piece 80 is bent or bent with respect to the vertical locking plate portion 74B. Therefore, the vertical locking plate portion 74 can be reliably tilted and displaced by the displacement of the locking release piece 80.

図11は、第2係止部74の横基板部74Aから係止解除片80および縦係止板部74に亘り、薄い鋼板を折曲げて形成した補強体102をインサートしたものである。この補強体102は、横基板部74A内に位置する第1補強部102Aと、第1補強部102Aから折曲されて係止解除片80内に位置する第2補強部102Bと、第2補強部102Bから折曲されて該係止解除片80から縦係止板部74に亘り延在する第3補強部102Cとからなる。このような補強体102を台に係止部74にインサートすることで、係止解除片80を押した際に、縦係止板部74Bに対して係止解除片80が撓んだり折曲することがなく、更に折れ難いため前記リブ82が不要となり、第1補強部102Aと第2補強部102Bとの接合部が変形することで、該係止解除片80の変位により縦係止板部74を確実に傾動変位させ得る。なお、図11の形態では、横基板部74Aに前記孔74Eが形成されていないが該孔74Eを形成してもよく、この場合に前記補強体102は、孔74Eに応じた形状に形成して用いることができる。   FIG. 11 shows a structure in which a reinforcing body 102 formed by bending a thin steel plate is inserted from the horizontal substrate portion 74 </ b> A of the second locking portion 74 to the locking release piece 80 and the vertical locking plate portion 74. The reinforcing body 102 includes a first reinforcing portion 102A positioned in the horizontal substrate portion 74A, a second reinforcing portion 102B bent from the first reinforcing portion 102A and positioned in the locking release piece 80, and a second reinforcing member. The third reinforcing portion 102 </ b> C is bent from the portion 102 </ b> B and extends from the locking release piece 80 to the vertical locking plate portion 74. By inserting the reinforcing body 102 into the locking portion 74 in the base, when the locking release piece 80 is pushed, the locking release piece 80 is bent or bent with respect to the vertical locking plate portion 74B. The rib 82 is unnecessary because it is not easily broken, and the joining portion between the first reinforcing portion 102A and the second reinforcing portion 102B is deformed. The portion 74 can be reliably tilted and displaced. In the form of FIG. 11, the hole 74E is not formed in the horizontal substrate portion 74A, but the hole 74E may be formed. In this case, the reinforcing body 102 is formed in a shape corresponding to the hole 74E. Can be used.
