Description

방음형 루버를 지닌 도어벤트 기구{Door ventilation device with acoustic louver}[0001] The present invention relates to a door ventilation device having an acoustic louver,

본 발명은 도어벤트 기구에 관한 것으로서, 보다 구체적으로는 선박에 탑재되는 루버형 도어의 저소음 규정을 만족하기 위한 방음형 루버를 지닌 도어벤트 기구에 관한 것이다.The present invention relates to a door vent mechanism, and more particularly, to a door vent mechanism having a soundproof louver for satisfying low noise specifications of a louver door mounted on a ship.

통상적으로 선박의 건조에 있어서 진동/소음과 관련된 규정이 적용되며 특정의 공사에는 도어 루버(Door louver)를 통한 통기(air ventilation) 과정의 소음을 감소시킨 저소음 설계를 요구하기도 한다. 이러한 소음의 발생은 실내외 압력차를 이용하는 도어루버벤트(Door louver ventilation)을 적용하는 경우 루버의 규격, 통기량 등을 주된 요인으로 한다.Vibration / noise related regulations are generally applied in the construction of ships, and certain constructions require a low noise design with reduced noise during air ventilation through door louvers. The generation of such noise is mainly caused by the louver specifications and the aeration amount when the door louver ventilation using the indoor and outdoor pressure difference is applied.

이에 대한 대응책 마련을 위해 참조할 수 있는 선행기술문헌으로서 한국 공개특허공보 제2014-0000363호(선행문헌 1), 한국 공개실용신안공보 제2015-0000646호(선행문헌 2) 등이 알려져 있다.Korean Patent Laid-Open Publication No. 2014-0000363 (Prior Art 1) and Korean Utility Model Publication No. 2015-0000646 (Prior Art 2) are known as prior art documents which can be referred to in order to prepare countermeasures thereto.

선행문헌 1은 내부가 관통형성되는 케이스; 상기 케이스의 외측에 장착되는 외측 커버; 상기 케이스의 내측에 장착되는 내측 커버; 상기 외측 커버와 내측 커버의 사이에 장착되면서 외부에서 내부로 이동하는 외부 공기의 소음을 음파 교란을 통해 절감하는 음향 절연부;를 포함한다. 이에, 루버로 전달되는 공기의 이동에 따른 소음을 감소시키는 효과를 기대한다.The prior art document 1 has a case in which the inside is penetrated; An outer cover mounted on the outside of the case; An inner cover mounted inside the case; And an acoustic insulation part installed between the outer cover and the inner cover to reduce noises of outside air moving from the outside to the inside through disturbance of sound waves. Thus, the effect of reducing noise due to the movement of the air transferred to the louver is expected.

선행문헌 2는 관통부를 갖는 선박용 도어에 설치되는 방음장치에 있어서: 상기 관통부에 탈착되며 흡음재질로 이루어져 소음원을 흡음하는 킥 아웃 패널; 상기 킥 아웃 패널의 상면에 고정되고 상기 킥 아웃 패널로 유입된 소음원을 상쇄시키는 공명기를 포함한다. 이에, 외관상으로 보이지 않아 형상이 미려하며, 선박 내부에서 발생하는 단일주파수를 차단하는 효과를 기대한다.A soundproofing device installed on a ship door having a penetrating portion, wherein the kickout panel is detachably attached to the penetrating portion and comprises a sound absorbing material and absorbs a noise source; And a resonator fixed on an upper surface of the kickout panel and offsetting a noise source introduced into the kickout panel. Therefore, it is expected that the shape will be beautiful because it can not be seen in appearance, and it will block the single frequency generated inside the ship.

다만, 상기한 선행문헌에 의하면 루버의 자유면적비(free area), 유속 등의 변동에 대응하여 도어개폐의 소음을 감소하는 유연성을 확보하는 차원에서 개선의 여지가 크다.However, according to the above-mentioned prior art, there is a lot of room for improvement in securing the flexibility to reduce the door opening / closing noise in response to the variation of the free area ratio and the flow velocity of the louver.

이하, 첨부된 도면에 의거하여 본 발명의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 방음형 루버를 지닌 도어벤트 기구에 관하여 제안한다. 본 발명은 선박에 탑재되는 도어의 저소음 규정을 만족하는 설계를 대상으로 하지만 반드시 이에 국한되는 것은 아니다. 도 1과 같은 방식으로 도어(10)에 루버(15)가 설치되는 경우 개폐작동으로 유발되는 소음을 감소시키기 한계성을 보인다.The present invention proposes a door vent mechanism with a soundproof louver. The present invention is intended to be a design that satisfies the low noise requirements of a door mounted on a ship, but is not necessarily limited thereto. When the louver 15 is installed on the door 10 in the same manner as in Fig. 1, it is difficult to reduce the noise caused by the opening / closing operation.

본 발명에 따르면 벤트도어(20)가 상하로 이격된 루버(21)(22)를 연결하는 통기덕트(25)를 구비하는 구조이다. 도 2에서 상부루버(21)는 외면에 하부루버(22)는 내면에 설치된 상태를 예시한다. 상부루버(21)와 하부루버(22)를 연결하는 통기덕트(25)는 "ㄱ"자와 "ㄴ"자를 상하로 이은 형태로 나타난다. 통기덕트(25)의 공기유동에 의한 압력손실은 덕트 유속과 자유면적 비에 따라 달라지므로 이를 감안하여 설계하여야 한다. 루버(21)(22)의 크기와 간격이 클수록 감음량이 증대되지만 도어의 개폐속도, 공기의 물성 등에 의해 변동될 수 있다.According to the present invention, the vent door (20) has a ventilation duct (25) for connecting the louvers (21) and (22) 2, the upper louver 21 has an outer surface and the lower louver 22 is disposed on the inner surface. The ventilation duct 25 connecting the upper louver 21 and the lower louver 22 is shown in a form of "a" and "b" up and down. The pressure loss due to the air flow of the ventilation duct (25) depends on the duct flow rate and the free area ratio. The greater the size and spacing of the louvers 21 and 22, the greater the amount of noise reduction may be, but may vary depending on the opening and closing speed of the door, the physical properties of the air, and the like.

본 발명의 세부 구성으로서, 상기 벤트도어(20)는 루버(21)(22) 상에 유로단면적을 변동하도록 가동날개(23)와 가동커버(27)를 구비하는 것을 특징으로 한다. 각각의 루버(21)(22)를 구성하는 다수의 가동날개(23)는 동시에 회동 가능하게 설치된다. 가동커버(27)는 루버(21)(22)의 개도면적을 변동하도록 벤트도어(20)의 내외면에 은폐 및 전개 가능하도록 설치된다.The vent door 20 is characterized in that the movable blade 23 and the movable cover 27 are provided on the louvers 21 and 22 so as to vary the cross-sectional area of the flow passage. A plurality of movable blades 23 constituting each of the louvers 21 and 22 are simultaneously rotatably installed. The movable cover 27 is installed so as to conceal and expand on the inner and outer surfaces of the vent door 20 so as to vary the opening areas of the louvers 21 and 22.

또, 본 발명에 따르면 흡음수단(30)이 상기 벤트도어(20)의 루버(21)(22)와 통기덕트(25)에 흡음재(31)(32)를 구비하는 구조이다. 흡음수단(30)은 통기덕트(25)에 설치되는 메인흡음재(31), 루버(21)(22)의 가동날개(23)에 설치되는 서브흡음재(32)를 구비한다. 메인흡음재(31)와 서브흡음재(32)는 다공성, 유연성, 내염수성, 난연성을 지닌 동일ㆍ유사한 소재를 사용할 수 있다. 통기덕트(25)의 경우 메인흡음재(31)에 더하여 특정 주파수의 소음 감소를 위한 공명형 흡음기(도시 생략)를 부가할 수도 있다.According to the present invention, the sound absorbing means 30 is provided with the sound absorbing members 31 and 32 in the louvers 21 and 22 of the vent door 20 and the air duct 25. The sound absorbing means 30 is provided with a main sound absorbing material 31 provided in the ventilation duct 25 and a sub sound absorbing material 32 provided in the movable vanes 23 of the louvers 21 and 22. The main sound absorbing material 31 and the sub sound absorbing material 32 may be the same or similar materials having porosity, flexibility, flame resistance and flame resistance. In the case of the ventilation duct 25, a resonance type sound absorber (not shown) for reducing the noise of a specific frequency may be added to the main sound absorption material 31. [

본 발명의 변형예로서, 상기 흡음수단(30)은 통기덕트(25) 상에 가동판(35)을 구비하여 공기 유동량에 연동하는 것을 특징으로 한다. 가동판(35)은 통기덕트(25)의 일부를 절개하고 위치이동(요동) 가능하게 설치한다. 가동판(35)의 이동력은 통기덕트(25)를 유동하는 공기압으로 유발되며, 궁극적으로 공기유동의 속도와 압력 증가에 기인한 소음 증가를 억제한다.As a modification of the present invention, the sound absorbing means (30) is provided with a movable plate (35) on the ventilation duct (25) and is interlocked with the amount of air flow. The movable plate 35 is provided so that a part of the ventilation duct 25 is cut and positionally moved (oscillated). The moving force of the movable plate 35 is caused by the air pressure flowing through the ventilation duct 25 and ultimately suppresses the noise increase due to the speed of the air flow and the pressure increase.

본 발명의 제1실시예로서, 상기 가동판(35)은 경사진 장공(41)을 개재하여 단축(42) 상에 위치변동 가능하게 설치되는 것을 특징으로 한다. 도 3에서, 장공(41)이 가동판(35)의 측면에서 우측으로 높아지게 형성된 상태를 예시한다. 가동판(35)은 통기덕트(25)에 설치된 단축(42)을 이용하여 장공(41) 상으로 결합한다. 이에 평상시 가동판(35)이 자중에 의한 처짐으로 통기덕트(25)에서 돌출되어 통기덕트(25)의 유로단면적을 축소하고, 도어의 개폐 과정에서 공기 유동량이 증가하면 가동판(35)이 부호 35'처럼 우상향으로 이동하면서 통기덕트(25)의 유로단면적을 증대한다. 물론 가동판(35)의 일측에 부착되는 메인흡음재(31)는 변형이 용이하도록 유연성을 지닌 소재로 형성된다.As a first embodiment of the present invention, the movable plate (35) is provided so as to be positionally variable on the short axis (42) via an inclined long hole (41). In Fig. 3, a state in which the long hole 41 is formed to be higher rightward from the side surface of the movable plate 35 is illustrated. The movable plate 35 is coupled on the long hole 41 by using the short shaft 42 provided in the ventilation duct 25. If the movable plate 35 normally protrudes from the ventilation duct 25 due to deflection due to its own weight to reduce the cross-sectional area of the flow path of the ventilation duct 25 and the amount of air flow increases during the opening and closing of the door, So that the flow path cross-sectional area of the ventilation duct 25 is increased. Of course, the main sound absorbing material 31 attached to one side of the movable plate 35 is formed of a material having flexibility to facilitate deformation.

본 발명의 제2실시예로서, 상기 가동판(35)은 일측에서 스프링(43)을 개재하여 탄성적으로 위치변동 가능하게 지지되고, 타측에서 노브(45)와 볼트(46)를 개재하여 위치변동의 범위를 제한하는 것을 특징으로 한다. 도 4에서, 가동판(35)은 우측에 설치된 스프링(43)에 의하여 좌측으로 통기덕트(25)의 유로단면적을 축소한다. 도 3과 마찬가지로, 도어의 개폐 과정에서 공기 유동량이 증가하면 가동판(35)이 우상향으로 이동하면서 통기덕트(25)의 유로단면적을 증대한다. 노브(45)는 벤트도어(20)의 내면에 설치되고, 소켓(48)은 가동판(35)의 일면에 설치되고, 볼트(46)는 노브(45)에 고정되는 동시에 소켓(48)에 회전 가능하게 수용된다. 이에, 노브(45)를 회전하면 스프링(43)을 압축하면서 가동판(35)의 위치변동을 허용하면서 초기위치를 결정한다.As a second embodiment of the present invention, the movable plate 35 is supported at one side by a spring 43 so as to be resiliently positionally displaceable, and at the other side of the movable plate 35 via a knob 45 and a bolt 46, And limits the range of fluctuation. In Fig. 4, the movable plate 35 reduces the flow path cross-sectional area of the ventilation duct 25 to the left by the spring 43 provided on the right side. As shown in FIG. 3, when the amount of air flow increases during the door opening / closing process, the movable plate 35 moves to the right side to increase the flow path cross-sectional area of the ventilation duct 25. The knob 45 is provided on the inner surface of the vent door 20 and the socket 48 is provided on one side of the movable plate 35. The bolt 46 is fixed to the knob 45, And is rotatably received. Thus, when the knob 45 is rotated, the initial position is determined while permitting the positional variation of the movable plate 35 while compressing the spring 43. [

이와 같이 본 발명은 상부루버(21)와 하부루버(22)의 단차로 인해 생긴 통기덕트(25) 상에 흡음재를 적용하므로 루버(21)(22)와 통기덕트(25) 상으로 유동되는 공기가 흡음재, 특히 가동판(35) 상의 메인흡음재(31)를 통과하면서 소음감소 효과를 나타낸다.As described above, according to the present invention, since the sound absorbing material is applied on the ventilation duct 25 formed by the step between the upper louver 21 and the lower louver 22, the air flowing into the louvers 21, 22 and the ventilation duct 25 Particularly, the main sound absorbing material 31 on the movable plate 35, thereby exhibiting a noise reduction effect.
