본 발명은 환기덕트용 댐퍼에 관한 것으로서, 더욱 상세하게는 환기덕트에 회전 개폐되어 냄새나 연가가 배출되도록 하거나 역류되는 것을 방지하도록 된 환 기덕트용 댐퍼에 관한 것이다.The present invention relates to a damper for ventilation ducts, and more particularly to a damper for ventilation ducts to be rotated and opened in the ventilation ducts to prevent odor or smoke from being discharged or prevented from flowing back.

일반적으로, 아파트나 빌라와 같은 공동주택이나 빌딩과 같은 고층건물에는 옥상으로 연통되는 공동구가 설치되고, 상기 공동구에는 건물의 각 실내로 분기되는 환기덕트가 연결되어 있으며, 각각의 분기된 환기덕트에는 어느 실내의 공기가 다른 실내로 유입되어 영향을 주지 않도록 댐퍼가 설치되되 댐퍼의 둘레부에는 씰링부재가 구비되어 기밀을 유지할 수 있도록 되어 있다.In general, high-rise buildings, such as apartments and villas, and high-rise buildings, such as buildings, are provided with communal ducts connected to the roof, and the communal ducts are connected with ventilation ducts branching to each interior of the building. A damper is installed so that air from one room does not enter and influence another room, but a sealing member is provided at the periphery of the damper to maintain airtightness.

이러한 댐퍼에 의하면, 예컨데, 주방에서 요리할 때 발생되는 연기를 배출할 경우에는 욕실이나 안방의 환기덕트에 설치된 댐퍼는 폐쇄되고 해당 환기덕트의 댐퍼는 개방되어, 요리시 발생되는 연기가 욕실이나 안방으로 유입되지 않고 건물의 공동구를 통해 외부로 배출되도록 한다. 즉, 각 환기덕트의 댐퍼는 필요한 실내의 환기를 위해서 선택적으로 개폐되도록 구성되는 것이 일반적이다. 또한, 외부의 화재시, 내부의 화재시에도 유독가스가 공동구를 따라 이동되는 것을 막기에 필수적인 구조인 것이다.According to such a damper, for example, when discharging smoke generated in a kitchen, the damper installed in the ventilation duct of the bathroom or the main compartment is closed and the damper of the ventilation duct is opened, so that the smoke generated during cooking is discharged from the bathroom or the main compartment. Do not enter the building, but let it out through the building's cavity. That is, the damper of each ventilation duct is generally configured to be selectively opened and closed for the necessary ventilation of the room. In addition, it is an essential structure to prevent the toxic gas from moving along the cavity in the event of an external fire.

그런데 종래의 댐퍼는 씰링부재가 단순히 댐퍼의 둘레부에 감싸져 있으므로, 댐퍼를 계폐작동시키는 과정에서 씰링부재가 덕트의 내벽면과 마찰접촉되면서 댐퍼에서 분리되는 경우가 빈번하게 발생하고, 이에 따라, 댐퍼가 덕트를 정확히 폐쇄하지 못하여 냄새나 연기가 역류되는 문제점이 있다.However, in the conventional damper, since the sealing member is simply wrapped around the damper, the sealing member is frequently separated from the damper while frictionally contacting the inner wall surface of the duct in the process of enclosing the damper. The damper does not close the duct correctly, there is a problem that the smell or smoke backflow.

따라서, 본 발명은 전술한 바와 같은 종래기술의 근본적인 문제점을 해결하기 위해 제안된 것으로서, 본 발명의 목적은 씰링부재가 댐퍼에서 분리되는 것을 방지하여 환기덕트를 정확히 폐쇄할 수 있도록 하고, 외기압이 발생되면 환기덕트와 접촉면적을 넓혀 기밀력을 향상시킬 수 있도록 된 새로운 구성의 환기덕트용 댐퍼를 제공하는 데 있다.Therefore, the present invention has been proposed to solve the fundamental problems of the prior art as described above, an object of the present invention is to prevent the sealing member from being separated from the damper to accurately close the ventilation duct, and the external air pressure The present invention provides a new configuration of the damper for the ventilation duct, which can improve the airtight force by increasing the contact area with the ventilation duct.

상기한 목적을 달성하기 위하여 본 발명은, 건물의 실내와 외부로 연통되도록 설치되는 덕트(100)의 내부에 회동 개폐가능하게 설치되며 둘레부에는 씰링부재(300)가 구비된 환기덕트용 댐퍼(200)에 있어서, 상기 씰링부재(300)는 상기 환기덕트용 댐퍼(200)를 감싸도록 금형에 금속 댐퍼(200)를 인서트성형하여 형성된 것을 특징으로 한다.In order to achieve the above object, the present invention is installed in the duct 100 is installed to communicate with the interior and exterior of the building to be rotatable open and close the damper for the ventilation duct provided with a sealing member 300 ( In 200, the sealing member 300 is formed by insert molding the metal damper 200 in a mold to surround the damper 200 for the ventilation duct.

이때, 상기 댐퍼(200)의 둘레부에는 둘레부를 따라 일정간격으로 통공(220)이 다수 형성되고, 댐퍼(200)의 일면과 타측면 부위를 깜싸는 씰링부재(300)의 일측부분과 타측부분이 상기 통공(220)을 통해 서로 일체로 연결되도록 하며, 상기 씰링부재(300)의 외측 둘레부에는 끝단부가 댐퍼(200)의 내측에 위치되는 밀폐날개(350)가 둘레부를 따라 일체로 형성되고, 상기 밀폐날개(350)는 외부의 공기가 유입되는 것을 방지하기 위하여 공동구 측으로 배치되며, 기밀을 위하여 덕트(100)의 내측면에 밀착되도록 형성한 것을 특징으로 한다.At this time, a plurality of through-holes 220 are formed in the circumferential portion of the damper 200 at predetermined intervals along the circumference, and one side portion and the other side portion of the sealing member 300 which blinks one side and the other side portion of the damper 200.

도시된 바와 같이, 본 발명에 따른 환기덕트용 댐퍼(200)는 시스크형상으로 이루어지며 건물의 실내와 외부로 연통되도록 설치된 원형의 덕트(100)의 내부 중앙에 모터(10)에 의해 회전되는 회전축(20)에 고정되어, 모터(10)의 구동에 따라 댐퍼(200)가 회동되어 덕트(100)를 개폐하도록 된 것으로, 댐퍼(200)의 둘레부에는 둘레부를 따라 씰링부재(300)가 댐퍼(200)의 둘레부를 감싸도록 구비되어 댐퍼(200)를 닫으면 상기 씰링부재(300)에 의해 덕트(100)를 완전히 밀폐시킬 수 있도록 구성되며, 상기 모터(10)는 덕트(100)의 외측에 브라켓(지시하지 않음)을 매개로 고정 장착된다.As shown, the damper for the ventilation duct 200 according to the present invention is made of a shek shape is rotated by the motor 10 in the inner center of the circular duct 100 installed to communicate with the interior and exterior of the building. It is fixed to the rotating shaft 20, the damper 200 is rotated in accordance with the driving of the motor 10 to open and close the duct 100, the sealing member 300 along the circumference of the damper 200 When the damper 200 is closed to close the damper 200, the damper 200 is configured to completely seal the duct 100 by the sealing member 300, and the motor 10 is disposed outside the duct 100. It is fixedly mounted on the bracket (not indicated).

이때, 본 발명에 따른 댐퍼(200)의 외곽 둘레부에는 원주방향을 따라 일정간격으로 원형의 통공(220)이 다수 관통형성되고, 상기 씰링부재(300)는 상기 댐퍼(200)의 통공(220)을 감싸도록 댐퍼(200)를 인서트성형하여 구비된다. 더 상세히 설명하면, 씰링부재를 링형상으로 성형한 후 기 성형된 씰링부재를 댐퍼(200)의 둘레부, 즉, 통공(220)을 감싸도록 댐퍼(200)의 둘레부에 결합되는 것이 아니라, 댐퍼(200)의 통공(220)을 감싸도록 댐퍼(200)를 인서트성형하여 댐퍼(200)의 둘레 부에 씰링부재(300)가 구비되도록 하게 된다.At this time, the outer periphery of the damper 200 according to the present invention is formed through a plurality of circular through holes 220 at regular intervals along the circumferential direction, the sealing member 300 is the through hole 220 of the damper 200 It is provided by insert-molding the damper 200 to surround the. In more detail, after the sealing member is molded into a ring shape, the pre-molded sealing member is not coupled to the circumference of the damper 200, that is, the circumference of the damper 200 to surround the through hole 220. The damper 200 is insert-molded to surround the through hole 220 of the damper 200 so that the sealing member 300 is provided at the circumference of the damper 200.

따라서, 본 발명에 따른 댐퍼(200)의 씰링부재(300)는 인서트성형하여 구비되므로, 도면에 도시된 바와 같이, 상기 댐퍼(200)의 통공(220)에 씰링부재(300)가 충진되어 댐퍼(200)의 상측 둘레부에 위치되는 상측부분(301)과 댐퍼(200)의 하측 둘레부에 위치되는 하측부분(303)이 서로 연결하는 연결부(310)가 마련되어 상하측부분(301,303)이 일체로 연결되도록 하게 된다.Therefore, since the sealing member 300 of the damper 200 according to the present invention is provided by insert molding, as shown in the drawing, the sealing member 300 is filled in the through-hole 220 of the damper 200 and the damper is filled. An upper portion 301 positioned at an upper circumference of the 200 and a lower portion 303 positioned at a lower circumference of the damper 200 are provided with a connecting portion 310 for connecting with each other, thereby allowing the upper and lower portions 301 and 303 to be integrated. Will be connected to.

따라서, 본 발명에 따른 씰링부재(300)는 그 둘레부에 통공(220)이 형성된 댐퍼(200)의 둘레부, 즉, 통공(220)을 감싸도록 댐퍼(200)를 인서트하여 성형하여 구비하여, 씰링부재(300)의 상하측부분(301,303)이 서로 일체로 연결되어 있으므로, 댐퍼(300)를 개폐작동킴에 따라 씰링부재(300)가 덕트(100)의 내벽면과 마찰접촉하더라도 댐퍼(200)에서 씰링부재(300)가 분리되는 것을 방지할 수 있으며, 이에 따라, 덕트(100)를 정확히 폐쇄하여 냄새나 연기가 역류되는 것을 방지할 수 있는 것이다.Therefore, the sealing member 300 according to the present invention is formed by inserting and molding the damper 200 to surround the periphery of the damper 200, that is, the through-hole 220 having the through-hole 220 formed at the periphery thereof. Since the upper and lower portions 301 and 303 of the sealing member 300 are integrally connected to each other, the damper 300 is opened and closed to operate the damper 300 even when the sealing member 300 is in frictional contact with the inner wall surface of the duct 100. The sealing member 300 can be prevented from being separated at 200, and thus, the duct 100 can be accurately closed to prevent odor or smoke from flowing back.

이때, 상기 씰링부재(300)의 외측 둘레부에는, 즉, 씰링부재(300)의 외측면 상단에는 끝단부가 댐퍼(200)의 내측에 위치되는 밀폐날개(350)가 둘레부를 따라 일체로 형성된다. 더 상세히 설명하면, 끝단부가 댐퍼(200)의 내측에 위치되되 외측으로 볼록하게 만곡지도록 호형상으로 밀폐날개(350)가 일체로 형성된다.At this time, the outer peripheral portion of the sealing member 300, that is, the upper end of the outer surface of the sealing member 300, the sealing wing 350, the end of which is located inside the damper 200 is integrally formed along the circumference. . In more detail, the closed end 350 is integrally formed in an arc shape so that the end portion is located inside the damper 200 but is curved convexly outward.

따라서, 상기 밀폐날개(350)는 평상시에 만곡진 상태로 유지하다가 댐퍼(200)의 상면측으로 외기압이 발생되면 도 4의 (B)에 도시된 바와 같이, 밀폐날개(350)가 상측으로 펼쳐지면서 덕트(100)의 내벽면에 밀착되도록 되어, 덕트(100) 와의 접촉면적을 넓혀 보다 확실하게 덕트(100)를 차단할 수 있는 것이다. Therefore, while the closed wing 350 is normally maintained in a curved state, when the outside air pressure is generated on the upper surface side of the damper 200, as shown in FIG. 4B, the closed wing 350 is extended upward. While being made to be in close contact with the inner wall surface of the duct 100, it is possible to block the duct 100 more reliably by increasing the contact area with the duct 100.

미설명 번호 30은 회전축(20)의 하측을 감싸는 고정브라켓이고, 번호, 40은 볼트와 너트로 이루어지며 상기 고정브라켓(30)과 댐퍼(200)를 체결하여 댐퍼(200)를 회전축(20)에 고정되도록 하는 체결구이다.Reference numeral 30 is a fixing bracket surrounding the lower side of the rotating shaft 20, the number, 40 is made of a bolt and nut, and the fixing bracket 30 and the damper 200 by fastening the damper 200 to the rotating shaft 20 Fastener to be fixed to.

이상에서와 같이 본 발명에 의하면, 댐퍼의 둘레부에 통공을 형성하고 상기 통공을 감싸도록 댐퍼를 인서트하여 씰링부재를 구비하되, 씰링부재의 상하측부분이 상기 통공에 충전되는 연결부에 의해 일체로 연결되어 있어 덕트와 마찰접촉하더라도 씰링부재가 댐퍼에서 분리되는 것을 방지할 수 있으므로, 덕트를 정확히 폐쇄시킬 수 있는 장점이 있다. 더욱이, 씰링부재에 외기압에 의해 펼쳐져 덕트의 내벽면에 밀착되는 밀폐날개를 구비하여 덕트와의 접촉면적을 넓힐 수 있어 보다 더 기밀을 향상시킬 수 있는 장점이 있다.As described above, according to the present invention, a through hole is formed in the periphery of the damper and the sealing member is provided by inserting the damper so as to surround the through hole, and the upper and lower parts of the sealing member are integrally connected by the connection part filled in the through hole. Since it is connected to prevent the sealing member from being separated from the damper even if the friction contact with the duct, there is an advantage to close the duct accurately. In addition, the sealing member is provided with a sealing wing that is expanded by the outside air pressure and is in close contact with the inner wall surface of the duct, so that the contact area with the duct can be widened, thereby further improving airtightness.
