Description

소음 기능을 가지는 필터 조립체{Filter assembly with silencing function}Filter assembly with silencing function

본 발명은 예를 들어 본 출원인의 대한민국 특허출원 10-2001-10268에 개시된 공기조화기의 산소부화공기 공급기에 설치되어 공기 압축기로부터 토출되는 압축 공기로부터 먼지와 같은 이물질을 제거하는 동시에 압축기의 압력 맥동을 저감할 수 있도록 소음 기능을 가지는 필터 조립체에 관한 것이다.The present invention is installed in the oxygen-enriched air supply of the air conditioner disclosed in, for example, the Republic of Korea Patent Application No. 10-2001-10268 of the present applicant to remove foreign substances such as dust from the compressed air discharged from the air compressor at the same time pressure pulsation of the compressor It relates to a filter assembly having a noise function to reduce the.

2001년 2월 28일자로 출원된 본 출원인의 대한민국 특허출원 10-2001-10268은 일반 공기에 비하여 산소의 농도가 훨씬 높은 산소부화공기를 실내로 공급할 수 있는 산소부화공기 공급기를 구비한 공기조화기를 개시하고 있다.The applicant's Korean Patent Application No. 10-2001-10268, filed on February 28, 2001, discloses an air conditioner with an oxygen-enriched air supply that can supply oxygen-enriched air with a much higher oxygen concentration than ordinary air. It is starting.

그리고, 상기의 공기조화기에 구비된 산소부화공기 공급기는 공기 압축기에서 압축된 공기로부터 이물질을 제거하기 위한 제 1 및 제 2 필터 조립체를 가지고 있다.In addition, the oxygen-enriched air supply unit provided in the air conditioner has first and second filter assemblies for removing foreign matter from the compressed air in the air compressor.

이 중에서 제 1 필터 조립체는 이물질을 제거하는 기능 외에도 압측기의 작동 과정에서 발생되는 압력 맥동에 의한 소음(騷音)을 제거하는 기능을 더 가지고 있다.Among these, the first filter assembly further has a function of removing noise caused by pressure pulsation generated during the operation of the pressure gauge in addition to the function of removing foreign substances.

이와 같이, 압력 맥동을 제거하기 위한 소음(消音) 기능을 가지는 필터 조립체는, 도 1에 도시된 바와 같이, 입구(11)와 출구(12)를 가지는 하우징(10)과, 하우징(10)의 내부에 설치된 필터(20)로 이루어져 있다. 하우징(10)의 입구(11)는 일측 방향으로 경사진 형상을 가지고 있다. 필터(20)는 상면이 개방된 원통 형상을 가지고 있으며, 개방된 상면은 하우징(10)의 출구(12)와 소통되어 있다.As such, the filter assembly having a noise function for removing the pressure pulsation includes a housing 10 having an inlet 11 and an outlet 12, as shown in FIG. It consists of a filter 20 installed inside. The inlet 11 of the housing 10 has a shape inclined in one direction. The filter 20 has a cylindrical shape with an open top surface, and the open top surface is in communication with the outlet 12 of the housing 10.

압축기에서 압축된 공기는 입구(11)를 통해 하우징(10)의 내부로 유입된다. 이때, 입구(11)가 일측 방향으로 경사져 있기 때문에, 하우징(10) 내로 유입된 공기에 소용돌이에 의한 와류가 발생된다. 이러한 와류 및 하우징(10) 내에서의 공명 효과에 의해 압축 공기의 압력 맥동은 저감되며, 공기가 필터(20)를 통과할 때 압력 맥동은 더 저감된다. 또한, 공기가 필터(20)를 통과할 때 먼지와 같은 공기에 포함된 이물질이 필터(20)에 의해 걸러진다.The compressed air in the compressor is introduced into the housing 10 through the inlet 11. At this time, since the inlet 11 is inclined in one direction, vortices due to vortex are generated in the air introduced into the housing 10. Due to this eddy current and resonance effect in the housing 10, the pressure pulsation of the compressed air is reduced, and when the air passes through the filter 20, the pressure pulsation is further reduced. In addition, when the air passes through the filter 20, foreign matter contained in the air such as dust is filtered by the filter 20.

그런데, 상기와 같은 종래의 필터 조립체는 하우징이 단순한 원통 형상을 가지고 있기 때문에, 공기가 입구를 통해 하우징 내부로 유입될 때 입구의 형상에 의해 발생되는 소용돌이에 의한 와류만 발생되며, 소용돌이에 의한 와류는 비교적 그 형태가 일정하다. 따라서, 종래의 필터 조립체로서는 와류에 의한 압력 맥동의 저감 효과가 낮은 단점이 있다.However, in the conventional filter assembly as described above, since the housing has a simple cylindrical shape, only the vortex caused by the vortex generated by the shape of the inlet is generated when air is introduced into the housing through the inlet, and the vortex caused by the vortex Is relatively constant in its form. Therefore, the conventional filter assembly has a disadvantage in that the effect of reducing the pressure pulsation due to vortex is low.

본 발명은 상기와 같은 점을 감안하여 안출된 것으로, 와류에 의한 압력 맥동의 저감 효과가 향상된 필터 조립체를 제공하는데 그 목적이 있다.The present invention has been made in view of the above, and an object thereof is to provide a filter assembly in which an effect of reducing pressure pulsation due to vortex is improved.

상기의 목적을 달성하기 위하여, 본 발명에 따른 필터 조립체는 압축기에서 압축된 유체로부터 이물질을 제거하는 동시에 압력 맥동을에 의한 소음을 제거하기 위한 것으로, 입구와 출구가 상면에 각각 형성된 원통형의 하우징; 상면이 개방된 원통형 부재로서 개방된 상면이 하우징의 출구와 소통하도록 하우징의 내부에 설치되어, 입구를 통해 하우징 내부로 유입되고 출구를 통해 하우징의 외부로 빠져나가는 유체 내에 포함된 이물질을 제거하기 위한 필터; 및 하우징의 내부로 유입된 유체에 와류가 크게 발생되도록 하우징의 내벽에 형성되는 다수의 와류 증대용 돌기를 포함한다. 다수의 와류 증대용 돌기는 하우징 측벽의 내면을 따라 링 형상으로 각각 형성된다.In order to achieve the above object, the filter assembly according to the present invention is to remove the foreign substances from the compressed fluid at the same time at the same time to remove the noise caused by the pressure pulsation, the inlet and outlet are formed in the upper housing; A cylindrical member having an open top surface, which is installed inside the housing so that the open top surface communicates with the outlet of the housing, for removing foreign matter contained in the fluid flowing into the housing through the inlet and exiting the outside of the housing through the outlet. filter; And a plurality of vortex augmentation protrusions formed on an inner wall of the housing such that vortices are largely generated in the fluid introduced into the housing. The plurality of vortex increasing protrusions are each formed in a ring shape along the inner surface of the side wall of the housing.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 2는 본 발명의 제 1 실시예에 따른 필터 조립체를 도시한다.2 shows a filter assembly according to a first embodiment of the invention.

도시된 바와 같이, 본 발명의 제 1 실시예에 따른 필터 조립체는 하우징(100), 필터(200), 및 다수의 와류 형성 돌기(300)를 포함하고 있다.As shown, the filter assembly according to the first embodiment of the present invention includes a housing 100, a filter 200, and a plurality of vortex forming protrusions 300.

하우징(100)은 입구(110)와 출구(120)가 상부에 형성되어 있는 대략 원통형의 부재이다. 하우징(100)의 입구는 압축기의 토출구와 소통되어 있고, 하우징(100)의 출구(120)는 제 2 필터 조립체를 통해 산소부화공기 분리기의 입구와 소통되어 있다.The housing 100 is a substantially cylindrical member having an inlet 110 and an outlet 120 formed thereon. The inlet of the housing 100 is in communication with the outlet of the compressor, and the outlet 120 of the housing 100 is in communication with the inlet of the oxygen enriched air separator via the second filter assembly.

필터(200)는 상면이 개방된 원통형의 부재이며, 개방된 상면이 하우징(100)의 출구(120)와 소통되도록 하우징(100)의 내부에 설치되어 있다. 이에 따라, 입구(110)를 통해 하우징(100)의 내부로 유입된 압축 공기는 반드시 필터(200)를 통과한 다음 출구(120)를 통해 하우징(100)의 외부로 유출된다. 그리고, 하우징(100)의 입구(110)는 하우징(100)의 내부로 유입되는 공기에 소용돌이(whirl)에 의한 와류가 발생될 수 있도록 그 내면이 일측으로 경사진 형상을 가진다.The filter 200 is a cylindrical member having an open top surface, and is installed inside the housing 100 such that the open top surface communicates with the outlet 120 of the housing 100. Accordingly, the compressed air introduced into the housing 100 through the inlet 110 necessarily passes through the filter 200 and then flows out of the housing 100 through the outlet 120. In addition, the inlet 110 of the housing 100 has a shape in which an inner surface thereof is inclined to one side so that vortices due to whirls may be generated in the air introduced into the housing 100.

다수의 와류 형성 돌기(300)는 하우징(100)의 측벽 내면에 각각 형성되어 있다. 본 발명의 제 1 실시예에서 와류 형성 돌기(300)는 하우징(100)의 내면을 따라 링 형상으로 형성되어 있으며, 삼각형의 단면 형상을 가지고 있다.A plurality of vortex forming projections 300 are formed on the inner surface of the side wall of the housing 100, respectively. In the first embodiment of the present invention, the vortex forming protrusion 300 is formed in a ring shape along the inner surface of the housing 100 and has a triangular cross-sectional shape.

이러한 구성으로 이루어진 본 발명의 제 1 실시예에 따른 필터 조립체에 있어서, 압축기에서 압축된 공기가 입구(110)를 통해 하우징(100)의 내부로 유입될 때 입구(110) 형상에 의해 소용돌이에 의한 와류가 발생되며, 이 와류는하우징(100)의 측벽 내면에 형성된 다수의 와류 형성 돌기(300)에 의해 더욱 증대된다. 그리고 나서, 하우징(100)의 내부의 공기는 필터(200)를 통과한 다음 하우징(100)의 출구(120)를 통해 외부로 유출된다.In the filter assembly according to the first embodiment of the present invention having such a configuration, when the compressed air in the compressor is introduced into the housing 100 through the inlet 110 by the vortex by the shape of the inlet 110 A vortex is generated, which is further augmented by a plurality of vortex forming protrusions 300 formed on the inner surface of the side wall of the housing 100. Then, the air inside the housing 100 passes through the filter 200 and then flows out through the outlet 120 of the housing 100.

유입되는 공기의 압력 맥동은 와류 및 하우징(100) 내부에서의 공명 현상에 의해 저감되고, 필터(200)를 통과할 때 다시 한번 더 저감된다. 여기서, 하우징(100)의 측벽 내면에 다수의 와류 형성 돌기(300)가 형성되어 있어 하우징(100) 내부로 유입된 공기의 와류가 더욱 증대되어 상호 간섭에 의한 압력 맥동의 저감 효과는 훨씬 커진다. 또한, 공기가 필터(200)를 통과할 때, 먼지와 같이 공기 중에 포함된 이물질은 필터(200)에 의해 걸러진다.Pressure pulsations of the incoming air are reduced by vortices and resonance phenomena inside the housing 100, and are once again reduced when passing through the filter 200. Here, the plurality of vortex forming protrusions 300 are formed on the inner surface of the side wall of the housing 100, so that the vortices of air introduced into the housing 100 are further increased, and the effect of reducing pressure pulsation due to mutual interference is much greater. In addition, when the air passes through the filter 200, foreign matter contained in the air, such as dust, is filtered by the filter 200.

도 3 및 도 4는 본 발명의 제 2 및 제 3 실시예를 각각 도시한다. 본 발명의 제 2 및 제 3 실시예는 상술한 제 1 실시예와 동일한 구성으로 이루어져 있고 그 작용도 동일하다. 다만, 와류 형성 돌기(300', 300")의 단면 형상이 각각 사각형 및 반원형으로 이루어져 있는 점이 제 1 실시예와 상이하다.3 and 4 show a second and a third embodiment of the present invention, respectively. The second and third embodiments of the present invention have the same configuration as the first embodiment described above, and the functions thereof are also the same. However, the point that the cross-sectional shapes of the vortex forming protrusions 300 'and 300 "are formed in a square and a semicircle, respectively, is different from the first embodiment.

상기된 바와 같은 본 발명에 따른 소음 기능을 가지는 필터 조립체는, 하우징의 측벽 내면에 다수의 와류 형성 돌기들이 형성되어 있기 때문에, 하우징의 내부로 유입된 공기의 와류는 더욱 증대되고 이에 따라 압력 맥동의 저감 효과는 훨씬 향상될 수 있다.In the filter assembly having the noise function according to the present invention as described above, since a plurality of vortex forming protrusions are formed on the inner surface of the side wall of the housing, the vortex of the air introduced into the housing is further increased, and thus the pressure pulsation is increased. The reduction effect can be much improved.

이상에서는, 본 발명을 특정의 바람직한 실시예에 대해서 도시하고 설명하였다. 그러나, 본 발명은 상술한 실시예에만 한정되는 것은 아니며, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 이하의 특허청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어남이 없이 얼마든지 다양하게 변경실시할 수 있을 것이다.In the above, the present invention has been illustrated and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention pertains may vary without departing from the spirit of the technical idea of the present invention described in the claims below. It may be changed.
