따라서 이러한 종래의 상기 에어크리너용 필터는 도 4에 도시된 바와 같이 상기 필터프레임(11)의 전후방측에 상기 필터엘리먼트(15)의 전후방을 차폐하는 차폐날개(11a)가 형성되어 상기 필터엘리먼트(15)의 전후방에 형성된 골로 공기가 통과하는 것을 차단한다.Therefore, the conventional air cleaner filter has a shielding blade 11a shielding the front and rear of the filter element 15 in front and rear sides of the filter frame 11, as shown in FIG. Block the passage of air to the bone formed in front and rear of 15).
그런데 이러한 종래의 상기 에어크리너용 필터는 전술한 바와 같이 상기 필터프레임(11)의 상기 삽입날개(11w)에 상기 가스킷(12)을 고정해야 하므로 상기 가스킷(12)을 별개로 제조해야 하고, 상기 필터프레임(11)의 전후방측에 상기 차폐날개(11a)를 형성하여야 하므로 제조비용이 과도하게 소요되는 문제점이 있다.However, the conventional air cleaner filter has to be manufactured separately from the gasket 12 because the gasket 12 must be fixed to the insertion blade 11w of the filter frame 11 as described above. Since the shielding blades 11a must be formed on the front and rear sides of the filter frame 11, there is a problem that excessive manufacturing cost is required.
또한 상기 차폐날개(11a)가 상기 필터엘리먼트(15)와 별개를 이루므로 상기 필터엘리먼트(15)의 상기 골을 확실하게 실링하지 못하여 여과되지 않은 공기가 상기 골을 통해 유입되는 문제점이 있다.In addition, since the shielding wing (11a) is separated from the filter element 15, there is a problem that the unfiltered air flows through the valleys because the shielding of the filter element (15) cannot be reliably sealed.
또한 에어크리너용 필터는 소모품이므로 일정거리의 주행시 마다 새것으로 교환됨에 따라 저가로 제조 및 판매되어야 하지만, 상기 필터프레임(11)이 고무로 구성되어 사출성형되므로 제조단가를 절감할 수 없다.In addition, since the air cleaner filter is a consumable, it must be manufactured and sold at a low price as it is replaced with a new one every time a certain distance is driven. However, since the filter frame 11 is made of rubber and injection molded, the manufacturing cost cannot be reduced.
특히, 사출성형시 고무레진을 고압으로 금형에 충전해야 하고, 금형을 가열하여 고무를 가황해야 하는 등의 과정으로 인하여 금형장비 및 운용비용이 과도하게 소요됨에 따라 제조단가를 절감할 수 없다.In particular, due to the process of filling the mold with a rubber resin at high pressure during the injection molding, and heating the mold to vulcanize the rubber, the manufacturing cost cannot be reduced due to excessive mold equipment and operating costs.
본 발명은 상부케이스 및 하부케이스의 결합부를 실링하는 종래의 가스킷을 구비하지 않아도 실링이 가능하고, 필터엘리먼트의 전후방측에 위치하는 골을 실링할 수 있고, 특히나 발포폼으로 성형되어 제조가 용이하고, 우레탄으로 발포되어 탄성력 및 방수성이 우수하고, 상부케이스 및 하부케이스의 결합력에 의해 압축되어 실링하는 실링부재가 구비되고, 하부케이스 및 필터엘리먼트 사이에 단턱을 제공하여 실링성을 향상시킬 수 있는 에어크리너용 필터를 제공한다.The present invention can be sealed without the conventional gasket for sealing the coupling portion of the upper case and the lower case, it is possible to seal the bone located in the front and rear sides of the filter element, in particular molded in foam foam and easy to manufacture It is foamed with urethane and has excellent elasticity and waterproofness, and is provided with a sealing member that is compressed and sealed by the coupling force of the upper case and the lower case, and provides air to improve the sealing property by providing a step between the lower case and the filter element.

상기 필터프레임(51)은 도 12에 확대 도시된 바와 같이 상기 필터엘리먼트(55)의 좌우측 양단이 인서트되어 상기 필터엘리먼트(55)가 수평상태로 고정된다.12, the left and right ends of the filter element 55 are inserted into the filter frame 51 to fix the filter element 55 in a horizontal state.
상기 필터프레임(51)은 방수가능한 탄성재로 이루어져서 도 7 및 도 8에 도시된 바와 같이 상기 필터엘리먼트(55)의 테두리를 따라 틀을 형성하며, 도 12에 도시된 바와 같이 상기 케이스(1)에 수평으로 내장되어 일부분이 상기 케이스(1)를 구성하는 상부케이스(1a) 및 하부케이스(1b)의 결합부에 끼워진 상태로 고정된다.The filter frame 51 is formed of a waterproof elastic material to form a frame along the edge of the filter element 55 as shown in Figures 7 and 8, the case (1) as shown in FIG. It is fixed in a state that is embedded in the horizontal portion fitted in the engaging portion of the upper case (1a) and lower case (1b) constituting the case (1).
상기 필터프레임(51)은 도 7에 도시된 바와 같이 대략 사각형의 틀로 구성되며, 방수재로 이루어져서 발포에 의해 사각형의 틀로 성형되는 발포폼으로 구성된다.The filter frame 51 is composed of a substantially rectangular frame as shown in Figure 7, it is composed of a foam foam formed of a rectangular frame by foaming the waterproof material.
상기 필터프레임(51)은 수분의 소통이 방지되는 미세한 크기의 공극으로 발포되어 방수가 가능하며, 이에 따라 공기의 소통도 실질적으로 제한할 수 있다.The filter frame 51 is foamed into a pore of a fine size to prevent the communication of moisture can be waterproof, thereby substantially limiting the communication of air.
상기 필터프레임(51)은 방수성 및 탄성력이 우수한 폴리우레탄으로 성형되는 것이 바람직하다.The filter frame 51 is preferably molded of polyurethane having excellent waterproofness and elasticity.
상기 필터프레임(51)은 상기 필터엘리먼트(55)의 테두리를 따라 발포되어 성형됨으로써 상기와 같이 사각형의 틀로 형성된다.The filter frame 51 is formed by foaming along the edge of the filter element 55 to form a rectangular frame as described above.
상기 필터프레임(51)은 도 12에 확대 도시된 바와 같이 좌우측의 내측으로 상기 필터엘리먼트(55)의 좌우측 양단이 인서트되도록 발포되어 성형된다.The filter frame 51 is foamed and molded so that both ends of the left and right sides of the filter element 55 are inserted into the left and right sides as shown in an enlarged view of FIG. 12.
따라서 상기 필터프레임(51)은 좌우측의 내측에 상기 필터엘리먼트(55)의 좌우측 양단이 일체로 고정된다.Therefore, the filter frame 51 is fixed to both ends of the left and right sides of the filter element 55 inside the left and right.
상기 실링돌기(51a)는 상기 필터프레임(51)과 동일한 재질로 형성되어 도 8 및 도 9에 도시된 바와 같이 상기 필터프레임(51)의 전후방측 하부면에 돌출상태로 연장형성된다. The sealing protrusion 51a is formed of the same material as the filter frame 51 and extends in a protruding state on the front and rear lower surfaces of the filter frame 51 as shown in FIGS. 8 and 9.
이때 상기 실링돌기(51a)는 도 8에 도시된 바와 같이 상기 필터프레임(51)의 전후방 양측에 하방으로 연장형성된다.In this case, the sealing protrusion 51a is extended downward in both front and rear sides of the filter frame 51, as shown in FIG.
상기 실링돌기(51a)는 도 7의 (b)와 도 10 및 도 11에 도시된 바와 같이 상기 필터엘리먼트(55)의 전후방측 길이방향을 따라서 상기 필터엘리먼트(55)의 상기 골(55b)에 삽입되어 상기 골(55b)을 실링한다.The sealing protrusion 51a is formed in the valley 55b of the filter element 55 along the longitudinal direction of the filter element 55 along the front and rear sides of the filter element 55 as shown in FIGS. 7B and 10 and 11. It is inserted to seal the valley 55b.
상기 실링돌기(51a)는 상기 필터프레임(51)과 동일한 재질로 이루어짐에 따라 폴리우레탄으로 이루어진 방수재 발포폼에 의해 발포로 성형된다.The sealing protrusion (51a) is formed of the foam by the foam foam made of a waterproof material made of polyurethane according to the same material as the filter frame 51.
상기 실링돌기(51a)는 상기 필터프레임(51)의 성형시 함께 성형되어 도 9에 도시된 바와 같이 상기 필터프레임(51)과 일체를 이룬다.The sealing protrusion 51a is molded together at the time of forming the filter frame 51 to form an integrated body with the filter frame 51 as shown in FIG. 9.
상기 실링돌기(51a)는 상기 필터엘리먼트(55)의 상기 골(55b)에 대응하는 형상으로 형성되므로 도 9에 도시된 바와 같이 대략 역삼각형을 이루면서 상기 필터프레임(51)의 하방으로 길게 형성된다.Since the sealing protrusion 51a is formed in a shape corresponding to the valley 55b of the filter element 55, the sealing protrusion 51a is formed to be elongated downward of the filter frame 51 while forming an approximately inverted triangle as shown in FIG. 9. .
한편, 상기 필터프레임(51)은 도 12에 도시된 바와 같이 돌출부(51b)가 구비된다.On the other hand, the filter frame 51 is provided with a protrusion 51b as shown in FIG.
상기 돌출부(51b)는 도 12에 확대된 바와 같이 상기 케이스(1)의 상기 상부케이스(1a)에 밀착되는 상부에 돌출형성된다.As the protrusion 51b is enlarged in FIG. 12, the protrusion 51b protrudes from the upper part in close contact with the upper case 1a of the case 1.
상기 돌출부(51b)는 상기 상부케이스(1a) 및 상기 하부케이스(1b)가 서로 밀착되어 조립됨에 따라 상기 상부케이스(1a) 및 상기 하부케이스(1b)에 의해 가압됨으로써 압축되어 상기 상부케이스(1a) 및 상기 하부케이스(1b)의 결합면을 실링한다.The protruding portion 51b is compressed by being pressed by the upper case 1a and the lower case 1b as the upper case 1a and the lower case 1b are in close contact with each other, thereby being compressed to the upper case 1a. ) And the coupling surface of the lower case (1b).
즉 상기 돌출부(51b)는 압축되어 상기 상부케이스(1a) 및 상기 하부케이스(1b) 사이에 공기가 소통되는 공극이 발생되지 않도록 한다.That is, the protrusion 51b is compressed so that air gaps between the upper case 1a and the lower case 1b do not occur.
또 한편, 상기 필터프레임(51)은 도 12에 확대된 바와 같이 걸림턱(51c)이 구비된다.On the other hand, the filter frame 51 is provided with a locking step (51c) as enlarged in FIG.
상기 걸림턱(51c)은 확대된 바와 같이 상기 케이스(1)의 상기 하부케이스(1b)에 밀착되는 하부에 단차형태로 형성되어 상기 하부케이스(1b)에 걸린다.The latching jaw 51c is formed in a stepped shape at a lower portion in close contact with the lower case 1b of the case 1 and is caught by the lower case 1b as enlarged.
따라서 상기 걸림턱(51c)은 상기 하부케이스(1b)의 내측 단부에 밀착되면서 상기 하부케이스(1b)의 내측 단부를 실링한다.Accordingly, the locking jaw 51c seals the inner end of the lower case 1b while being in close contact with the inner end of the lower case 1b.
상기와 같이 구성된 본 발명에 따른 에어크리너용 필터의 제조방법 및 작용을 설명하면 다음과 같다.Referring to the manufacturing method and action of the air cleaner filter according to the present invention configured as described above are as follows.
본 발명에 따른 에어크리너용 필터(50)는 완제품의 제조를 위해 우선, 도 8에 도시된 바와 같은 상기 필터엘리먼트(55)를 미도시된 발포폼 성형틀의 내부에 삽입한다.The filter 50 for an air cleaner according to the present invention first inserts the filter element 55 as shown in FIG. 8 into the foam foam forming mold (not shown) to manufacture a finished product.
이때 상기 필터엘리먼트(55)는 상기 산(55a)과 상기 골(55b)이 형성된 상태로 상기 발포폼 성형틀의 내부에 삽입된다.In this case, the filter element 55 is inserted into the foam foam mold in a state in which the peak 55a and the valley 55b are formed.
그리고 상기 발포폼 성형틀에 폴리우레탄으로 이루어진 발포제를 주입하여 상기 필터엘리먼트(55)의 테두리를 따라 발포제를 발포시킨다.Then, a foaming agent made of polyurethane is injected into the foaming mold to foam the foaming agent along the edge of the filter element 55.
이때 상기 발포제는 상기 발포폼 성형틀에 상기 실링돌기(51a)가 성형되는 케비티(미도시)가 형성됨에 따라 상기 필터엘리먼트(55)의 양측을 따라, 즉 상기 필터엘리먼트(55)의 전후방 테두리를 따라 상기 골(55b)에 주입된 후 발포된다.In this case, the foaming agent is formed along the both sides of the filter element 55, that is, the front and rear edges of the filter element 55, as the cavity (not shown) is formed in the foam forming mold forming the sealing protrusion (51a). It is injected into the bone 55b and then foamed.
따라서 상기 발포제는 발포가 완료되면, 도 8 및 도 9에 도시된 바와 같이 상기 실링돌기(51a)가 전후방을 따라 형성된 상기 필터프레임(51)으로 변환된다.Therefore, when the foaming agent is completed foaming, the sealing protrusion 51a is converted into the filter frame 51 formed along the front and rear as shown in FIGS. 8 and 9.
이때 상기 필터프레임(51)은 도 12에 확대 도시된 바와 같이 좌우측 양단부에 상기 필터엘리먼트(55)의 양단부가 인서트됨으로써 상기 필터엘리먼트(55)와 일체를 이룬다.At this time, the filter frame 51 is integrally formed with the filter element 55 by inserting both ends of the filter element 55 at both left and right ends thereof, as enlarged in FIG. 12.
또한 상기 실링돌기(51a)는 도 10 및 도 11에 도시된 바와 같이 상기 필터엘리먼트(55)의 전후방측 테두리에 형성된 상기 골(55b)로 삽입되어 상기 필터엘리먼트(55)의 표면에 고착됨으로써 상기 필터엘리먼트(55)의 상부면에 일체로 고정된다.In addition, the sealing protrusion 51a is inserted into the valley 55b formed at the front and rear edges of the filter element 55, as shown in FIGS. 10 and 11, thereby fixing the sealing protrusion 51a to the surface of the filter element 55. It is fixed to the upper surface of the filter element 55 integrally.
한편, 상기 필터프레임(51)은 상기 발포폼 성형틀에 의해 도 12에 확대된 바와 같이 전술한 상기 돌출부(51b)가 형성되고, 상기 걸림턱(51c)이 형성될 경우 상기 케이스(1)의 상기 상부케이스(1a) 및 상기 하부케이스(1b) 사이를 거의 완전하게 실링하고, 상기 하부케이스(1b)의 내측 테두리를 실링한다.On the other hand, the filter frame 51 is formed by the foam foam forming mold as shown in the above-described protrusion (51b) is formed, and when the locking step (51c) is formed of the case (1) The upper case 1a and the lower case 1b are sealed almost completely, and the inner edge of the lower case 1b is sealed.
따라서 상기 필터프레임(51)은 상기 필터엘리먼트(55)의 테두리를 따라 원활하게 실링한다.Therefore, the filter frame 51 seals smoothly along the edge of the filter element 55.
상기와 같은 본 발명에 따른 에어크리너용 필터(50)는 필터프레임(51) 및 실링돌기(51a)가 방수성 탄성재로 구성되어 상부케이스(1a) 및 하부케이스(1b)의 결합부를 실링하는 종래의 가스킷을 구비하지 않아도 실링이 가능함으로써 제조비용을 절감할 수 있고, 실링돌기(51a)가 필터엘리먼트(55)의 전후방측에 위치하는 골을 차폐하여 실링함으로써 필터엘리먼트(55)의 골을 통해 공기가 유입되는 것을 확실하게 방지할 수 있고, 상기 필터프레임(51) 및 상기 실링돌기(51a)가 발포폼으로 성형됨으로써 제조가 용이하여 제조단가를 절감할 수 있고, 상기 필터프레임(51) 및 상기 실링돌기(51a)가 우레탄으로 발포되어 탄성력 및 방수성이 우수함으로써 우수한 실링성 및 조립성을 제공할 수 있고, 상기 필터프레임(51)에 돌출부가 형성되어 상부케이스(1a) 및 하부케이스(1b)의 결합력에 의해 압축됨으로써 상부케이스(1a) 및 하부케이스(1b)의 결합부를 확실하게 실링할 수 있고, 필터프레임(51)에 걸림턱이 형성되어 하부케이스(1b) 및 필터엘리먼트(55) 사이에 단턱을 제공함으로써 2차로 실링성을 향상시킬 수 있는 효과가 있다.The air cleaner filter 50 according to the present invention as described above is a filter frame 51 and the sealing projection (51a) is made of a waterproof elastic material to seal the coupling portion of the upper case (1a) and lower case (1b). The manufacturing cost can be reduced by sealing even without the gasket of the gasket, and the sealing protrusion 51a shields and seals the valleys located at the front and rear sides of the filter element 55 through the valleys of the filter element 55. The inflow of air can be reliably prevented, and the filter frame 51 and the sealing protrusion 51a are molded into a foam, so that manufacturing is easy, and manufacturing cost can be reduced, and the filter frame 51 and The sealing protrusion 51a is foamed with urethane to provide excellent sealing and assembly properties by having excellent elasticity and waterproofness, and a protrusion is formed on the filter frame 51 to form an upper case 1a and a lower cable. Compression by the coupling force of (1b) makes it possible to reliably seal the engaging portion of the upper case (1a) and the lower case (1b), the locking jaw is formed in the filter frame 51, the lower case (1b) and the filter element ( By providing a step between the 55) there is an effect that can improve the sealing property in the secondary.
한편, 상기 실링돌기(51a)는 도 13 및 도 14에 도시된 바와 같이 외측면, 즉 상기 필터프레임(51)의 외곽을 향하는 일면에 외측판(51a-1)이 동일체로 형성될 수 있다. 외측판(51a-1)은 실링돌기(51a)의 발포시 함께 발포된다.Meanwhile, as illustrated in FIGS. 13 and 14, the sealing protrusion 51a may have the same outer plate 51a-1 on the outer surface, that is, the outer surface 51a of the filter frame 51. The outer plate 51a-1 is foamed together at the time of foaming of the sealing protrusion 51a.
외측판(51a-1)은 실링돌기(51a)가 필터엘리먼트(55)의 외측으로 이탈되는 것을 방지한다. 즉, 전술한 도 7 내지 도 12에 도시된 실링돌기(51a)는 역삼각형의 가느다란 막대형으로 형성되므로 공기의 유입시 공기압에 의해 필터엘리먼트(55)의 골(55b)에서 필터엘리먼트(55)의 외측으로 이탈되거나, 조립작업시 필터엘리먼트(55)의 외측으로 이탈될 수 있다. 하지만, 전술한 외측판(51a-1)이 마련될 경우 실링돌기(51a)는 외측판(51a-1)의 강성에 의해 쉽게 외측으로 밀려나지 않는다. 이때, 외측판(51a-1)은 필터프레임(51)의 하방으로 연장형성될 뿐만 아니라 자중이 작용하므로 실링돌기(51a)가 필터엘리먼트(55)의 외측으로 이탈되는 것을 방지한다. 또한, 외측판(51a-1)은 실링돌기(51a)와 마주하는 면이 발포에 의해 필터엘리먼트(55)의 표면에 부착되므로 실링돌기(51a)의 이탈을 더욱더 억제한다. 따라서, 실링돌기(51a)는 필터엘리먼트(55)의 측방에 견고하게 고정된다.The outer plate 51a-1 prevents the sealing protrusion 51a from being separated out of the filter element 55. As shown in FIG. That is, since the sealing protrusion 51a illustrated in FIGS. 7 to 12 is formed as a slender rod of an inverted triangle, the filter element 55 is formed at the valley 55b of the filter element 55 by the air pressure when air is introduced. ) Or may be separated to the outside of the filter element 55 during the assembly operation. However, when the above-described outer plate 51a-1 is provided, the sealing protrusion 51a is not easily pushed out by the rigidity of the outer plate 51a-1. At this time, the outer plate (51a-1) is formed to extend below the filter frame 51 as well as the self-weight acts to prevent the sealing projection (51a) is separated from the outside of the filter element (55). In addition, since the surface facing the sealing projection 51a is attached to the surface of the filter element 55 by foaming, the outer plate 51a-1 further suppresses the separation of the sealing projection 51a. Therefore, the sealing protrusion 51a is firmly fixed to the side of the filter element 55. As shown in FIG.
여기서, 전술한 외측판(51a-1)은 도 13에 도시된 바와 같이 다수의 편과 같은 형태로 구성될 수 있으며, 이와 달리 도 15 및 도 16에 도시된 바와 같이 필터프레임(51)의 길이방향을 따라 길게 형성되는 판재형태로 구성할 수도 있다. Here, the aforementioned outer plate 51a-1 may be configured in the form of a plurality of pieces as shown in FIG. 13, and alternatively, the length of the filter frame 51 as shown in FIGS. 15 and 16. It can also be configured in the form of a plate formed long along the direction.
외측판(51a-1)은 도 15 및 도 16에 도시된 바와 같이 판재형태로 구성될 경우 도 13에 도시된 다수의 편과 같은 구조보다 강성이 강화되므로 실링돌기(51a)를 필터엘리먼트(55)의 측방에 좀더 견고하게 고정할 수 있다. 이때, 외측판(51a-1)은 다수의 편과 같이 분리되지 않고 판재형태로 형성되어 일체형으로 구성되므로 강성이 강화된다. 따라서, 실링돌기(51a)는 도 13 및 도 14의 구조에서 보다 좀더 견고하게 필터엘리먼트(55)의 측방에 고정된다.When the outer plate (51a-1) is configured in the form of a plate, as shown in Figure 15 and 16, because the rigidity is strengthened than the structure such as a plurality of pieces shown in Figure 13, the sealing projection (51a) filter element 55 Can be fixed more firmly on the side of). At this time, since the outer plate (51a-1) is formed in a plate shape without being separated like a plurality of pieces are formed in one piece, the rigidity is reinforced. Therefore, the sealing protrusion 51a is fixed to the side of the filter element 55 more firmly in the structure of FIGS. 13 and 14.
이러한 판재형의 외측판(51a-1)은 전술한 다수의 편과 같은 구조에 비해 재료비가 좀더 소요되는 것이 단점이지만, 실링돌기(51a)를 더욱 안정적으로 고정시킬 수 있는 이점이 있다.Such a plate-shaped outer plate (51a-1) is a disadvantage in that the material cost is more than the structure, such as a plurality of pieces described above, there is an advantage that can be more stably fixed to the sealing projection (51a).
