CONSTITUTION: An air cleaner for an automobile comprises a top body(100), a bottom body(200), a filter element(300), and a resonant plate(400). The top body forms a partition wall(120) downwardly having a constant interval with a one-side wall(110). A closure(130) for filtered air and a closure for a resonator chamber(140) separating an opening part of a bottom surface are formed. The opening part of the closure for the filtered air is blocked by equipping the filter element in an edge end(210) of an upper side of the bottom body. A filter for the resonator chamber blocks an opening part of the closure for the resonator chamber by protruding a neck(410) in a regular length downwardly. In the air cleaner, an intake noise is reduced.

Description

자동차용 에어클리너{Air cleanerfilter for automobile}Air cleaner for automobile {

본 발명은 자동차용 에어클리너에 관한 것으로서 더욱 상세히는 레조네이터를 별도로 제작하여 설치하지 않고 에어클리너를 이용하여 흡기소음을 저감시킬 수 있음에 따라 레조네이터를 제작하기 위한 비용을 절감하여 전체적인 차량가를 낮추는데 일조를 할 수 있는 것은 물론 협소한 엔진룸내에서 레조네이터를 설치하기 위한 공간을 확보할 필요가 없어 엔진룸내의 공간 활용도를 높일 수 있는 자동차용 에어클리너에 관한 것이다.
The present invention relates to an air cleaner for an automobile, and more particularly, it is possible to reduce intake noise by using an air cleaner without manufacturing and installing a separate resonator, thereby reducing the overall vehicle price by reducing the cost for manufacturing a resonator. Of course, the present invention relates to a car air cleaner that can increase the space utilization of the engine room without having to secure a space for installing a resonator in a narrow engine room.

일반적으로 자동차의 흡기장치는 에어덕트를 통해 유입된 공기가 정화되는 에어클리너와 에어클리너와 흡기매니폴드의 서지탱크를 연결하는 에어인테이크 호스와 서지탱크에 장착되는 스로틀바디와 흡입된 공기를 각 실린더로 분배할 수 있도록 구분된 배출 포트를 구비한 흡기 매니폴드 등으로 이루어진다.In general, the intake device of a vehicle includes an air cleaner for purifying the air introduced through the air duct, an air intake hose connecting the air cleaner and the surge tank of the intake manifold, and a throttle body mounted on the surge tank and the intake air. And an intake manifold with a separate discharge port for dispensing.

이러한 흡기장치를 통해 엔진의 실린더로 공급되는 외부의 공기는 엔진의 흡기부압에 의해 부압되는데 이때 공기가 흡입되면서 유동할 때 공기유동에 따른 흡기소음이 차 실내로 전달되어 승차감이 떨어지는 것이다.The outside air supplied to the cylinder of the engine through the intake apparatus is negative pressure by the intake negative pressure of the engine at this time, when the air flows while the air is sucked intake noise due to the air flow is delivered to the interior of the vehicle is less ride comfort.

즉, 흡기장치에서 발생하는 소음의 진동수와 차체의 고유 진동수가 일치하는 경우 공명현상이 일어나는 것이고 이러한 공명현상에 의해 부밍노이즈가 발생하여 실내로 전달되는 것이다.That is, when the frequency of the noise generated from the intake apparatus and the natural frequency of the vehicle body coincide with each other, a resonance phenomenon occurs, and the resonance phenomenon generates booming noise and is transmitted to the room.

따라서 흡기장치에서 발생하는 소음을 저감시키기 위하여 흡기시스템을 특정 주파수로 튜닝하기 위한 공명식 레조네이터를 장착하게 되는데 이 레조네이터는 엔진의 흡,배기행정 및 피스톤의 왕복운동에 따른 흡기소음중 특정주파수를 공진시켜 제거하게 된다.Therefore, in order to reduce noise generated in the intake device, a resonance type resonator for tuning the intake system to a specific frequency is installed. The resonator resonates a specific frequency of intake noise due to the intake and exhaust stroke of the engine and the reciprocating motion of the piston. Will be removed.

즉, 상기의 레조네이터는 흡배기 통로를 따라 흐르는 특정 주파수의 소음을 공명의 원리를 이용하여 저감시키는 장치로서 레조네이터의 부피(V)와 네크의 길이(L) 및 네크의 단면적(A)에 따라 흡기소음의 진동수(fr)를 결정하게 되는데 그 진동수(fr)는 헬름헬쯔 공명공식

Figure pat00001
에 의해 정해지는 것이다.In other words, the resonator is a device for reducing the noise of a specific frequency flowing along the intake and exhaust passage using the principle of resonance, the intake noise according to the volume (V) of the resonator, the length of the neck (L) and the cross-sectional area (A) of the neck. To determine the frequency (fr) of the frequency (fr) is the Helm Hetz resonance formula
Figure pat00001
It is decided by.

따라서 종래에는 도 1에서와 같이 에어클리너(10)의 일측에 별도의 레조네이터를 설치하는데 레조네이터는 소정크기의 부피를 가지는 레조네이터함체(20)와 레조네이터함체(20)의 일측에 에어클리너(10)와 연동되게 설치된 넥크(30)로 이루어진다.Therefore, in the related art, a separate resonator is installed on one side of the air cleaner 10 as shown in FIG. 1, but the resonator has an air cleaner 10 and one side of the resonator enclosure 20 and the resonator enclosure 20 having a volume of a predetermined size. It consists of a neck 30 installed to interlock.

이처럼 흡기소음 저감을 위해 레조네이터를 별도로 제작하여 설치하기 때문에 레조네이터 제작에 따른 비용이 추가되는 것이고, 이처럼 추가되는 비용은 흡기시스템 전체의 원가에 상당한 영향을 끼치게 되어 전체적으로 차량가를 높이는 원인이 된다.As the resonator is manufactured and installed separately to reduce intake noise, the cost of the resonator is added, and the added cost significantly affects the cost of the entire intake system, thereby increasing the overall vehicle price.

또한, 레조네이터가 설치되는 곳은 엔진룸이고, 엔진룸은 자동차의 구동에 필요한 수많은 부품이 설치되는 곳이기 때문에 그만큼 공간이 협소하여 레조네이터함체(20)와 넥크(30)가 놓여지는 공간을 확보 하는데 어려움이 있는 것이므로 그만큼 엔진룸내의 공간 활용도가 떨어지는 문제점이 있었다.
In addition, the place where the resonator is installed is the engine room, and the engine room is a place where a large number of parts necessary for driving the car are installed so that the space is narrow so as to secure a space in which the resonator enclosure 20 and the neck 30 are placed. Since there is a difficulty, there was a problem in that the space utilization in the engine room falls.

이에 본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로 본 발명의 목적은 레조레이터를 별도로 제작하여 설치하지 않고서도 흡기소음을 저감시킬 수 있음에 따라 레조네이터 제작에 따른 비용을 절감하여 전체적인 차량가를 낮추는데 일조할 수 있는 것이고, 또한 협소한 엔진룸내에서 레조네이터를 설치하기 위한 공간을 확보할 필요가 없어 엔진룸내의 공간 활용도를 높일 수 있는 자동차용 에어클리너를 제공하기 위한 것이다.
Accordingly, the present invention is to solve such a conventional problem, and an object of the present invention is to reduce the intake noise by lowering the overall vehicle price by reducing the intake noise as the intake noise can be reduced without separately manufacturing and installing the regulator. It is possible to help, and also to provide a car air cleaner that can increase the space utilization in the engine room because there is no need to secure a space for installing the resonator in the narrow engine room.

In order to achieve the object of the present invention, the upper body of the air cleaner is formed as a compartment for the filtration air and the resonance chamber to form a partition wall downwards at a predetermined distance from the one side wall and the opening of the bottom is separated from each other, the lower At the upper edge of the body, a filter element that blocks the opening of the filter air enclosure and a neck of a predetermined length protrude downward to install a resonance plate that blocks the opening of the resonance chamber, thereby reducing intake noise in the air cleaner itself. do.

이와 같은 본 발명은 에어클리너에 레조네이터 기능을 부여하여 별도의 레조네이터를 제작하여 설치하지 않고서도 흡기소음을 저감시킬 수 있음에 따라 레조네이터 제작에 따른 비용을 절감할 수 있는 것은 물론 협소한 엔진룸내에서 설치공간을 확보할 필요가 없어 엔진룸의 공간활용도를 높일 수 있는 효과가 있다.
As such, the present invention provides a resonator function to the air cleaner to reduce the intake noise without producing and installing a separate resonator, thereby reducing the cost of the resonator manufacturing and installing in a narrow engine room. There is no need to secure a space, which increases the space utilization of the engine room.

그리고 하부몸체(200)의 상측 테두리단(210)에는 여과공기용 함체(130)의 개구부를 막는 필터엘리먼트(300)와, 일정 길이의 넥크(410)가 하향으로 돌출되어 공명실용 함체(140)의 개구부를 막는 공명판(400)을 설치하여 에어클리너 자체에서 흡기소음이 저감되게 한 것을 특징으로 한다.And the upper edge end 210 of the lower body 200, the filter element 300 to block the opening of the filter air housing 130, and the neck 410 of a predetermined length protrudes downward to the resonance chamber enclosure 140 By installing the resonance plate 400 to block the opening of the air cleaner itself, characterized in that the intake noise is reduced.

이와 같은 본 발명은 자동차의 엔진룸에 흡기소음을 저감시키기 위한 장치를 설치하여 흡기소음을 저감시켜 탑승자의 승차감을 향상시키도록 한 것은 종래와 마찬가지이다.As described above, the present invention provides a device for reducing intake noise in an engine room of an automobile to reduce intake noise to improve a passenger's riding comfort.

그러나 본 발명에서의 특징은 흡기소음을 저감시키기 위하여 레조네이터를 별도로 제작하던 것을 삭제할 수 있음에 따라 레조네이터 제작 비용을 절감할 수 있는 것은 물론 레조네이터 설치 공간을 확보할 필요가 없어 엔진룸의 공간 활용도를 높일 수 있도록 한 것이다.However, the feature of the present invention is that it is possible to delete the resonator manufactured separately to reduce the intake noise, which can reduce the cost of manufacturing the resonator as well as to increase the space utilization of the engine room without having to secure the resonator installation space. I would have to.

즉, 본 발명은 에어클리너의 상부몸체(100)에 일측벽(110)과 일정간격이 유지되게 격벽(120)을 형성하여 상부몸체(100)에 여과공기용 함체(130)와 공명실용 함체(140)가 형성되게 한다.That is, the present invention forms the partition wall 120 to maintain a constant distance and the one side wall 110 in the upper body 100 of the air cleaner to filter the air chamber 130 and the resonance chamber in the upper body 100 ( 140) is formed.

그리고 에어클리너의 하부몸체(200)에는 필터엘리먼트(300)와 일정 길이의 넥크(410)가 하향으로 돌출되는 공명판(400)을 설치한다.And the lower body 200 of the air cleaner is provided with a resonance plate 400, the filter element 300 and the neck 410 of a predetermined length protrudes downward.
