Description

역류방지용 댐퍼{A damper for intercepting of adverse wind}A damper for intercepting of adverse wind}

본 발명은 실내기류등을 환풍시키기 위하여 송풍기 통로상에 설치되는 역류방지용 댐퍼에 관한 것으로 안내부재와 함께 기류개폐수단으로 비닐막을 부착시킨 역류방지용 댐퍼에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backflow prevention damper installed on a blower passage for ventilating indoor airflow, and the like, and a backflow prevention damper having a vinyl film attached to the airflow opening and closing means together with a guide member.

종래에는 첨부 도면 도 3a와 도 3b에서 도시하는 바와같이 기류를 받는 측으로 오목하게 요입되고 편심된 유동축을 가진댐퍼가 사용되었다.Conventionally, a damper having a flow shaft concave recessed and eccentric to a side receiving air flow is used, as shown in FIGS. 3A and 3B.

그러나 송풍코자 하는 기류의 배기시에는 배기력에 의하여 축을 중심으로 개도가 개방되기는 하나, 반대로 역류방지를 위하여 불룩하게 가이드면을 형성하기는 하였으나 역류가 불어 올때에도 후방으로 개도를 어느 정도 허용하는 문제점이 있었다.However, although the opening degree is opened around the axis by the exhaust force when the air flow is intended to be blown, the guide surface is formed bulge to prevent the reverse flow, but the opening degree is allowed to some extent even when the backflow blows. There was this.

배기력과 역류 기류의 힘이 동일할 때에는 댐퍼는 개도를 개방하지 못한다. 그러나 송풍기의 배기력을 보다 강하게 집속하면서 가볍게 배기시키는 구조가 가능하다면 종래와 같은 단지 편심축 유동에 의한 댐퍼에 비하여 보다 개도를 여는 힘은 개선할 수 있다.The damper does not open the opening when the forces of exhaust and backflow are equal. However, if a structure capable of lightly exhausting the exhaust air of the blower while concentrating it more strongly, the opening force can be improved as compared with the conventional damper by eccentric shaft flow.

본 발명은 단지 편심축을 구비하고, 역류방지측이 불룩한 형태의 단순 댐퍼가 갖는 단순구조를 탈피하여 송풍기로 부터의 배기를 집속하도록 하면서 보다 간단한 구조의 댐퍼수단으로 배기개도를 개방가능하도록 하는 고정식 댐퍼를 제공하는 데에 그 목적이 있다.The present invention has a fixed damper which has an eccentric shaft, and allows the exhaust opening to be opened by a damper means having a simpler structure while concentrating exhaust from the blower by escaping the simple structure of the simple damper having a bulging back side. The purpose is to provide.

Guide members protruding from the upper and lower ends of the frame, respectively; A slim vinyl film formed with long cutting holes in the upper and lower parts of the center so as to be elastically opened and closed at both sides of the center in the vertical direction from the rear of the guide member, and the fixing holes are coupled to the fixing protrusions of the guide member; And it is achieved as a backflow prevention damper comprising a piece of film formed in each of the fixing holes in the upper, middle, and bottom of the rectangle to fix the vinyl film to the guide member.

상기한 안내부재는 그 후방 소정위치에 고정돌기를 돌설하고, 비닐막은 이 고정돌기에 끼워지는 구멍을 직선방향 형성하며,그 직선방향을 따라 절취공을 형성하여서 된다. 또한 상기 비닐막은 그의 결합을 위하여 고정공이 형성된 조각막을 더포함함이 바람직하다,The guide member protrudes a fixing projection at a predetermined rear position thereof, and the vinyl film forms a hole inserted into the fixing projection in a linear direction, and forms a cutting hole along the linear direction. In addition, it is preferable that the vinyl film further includes an engraving film having a fixing hole formed therein for bonding thereof.

이하 본 발명의 바람직한 실시예를 첨부 도면에 따라 구체적으로 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부 도면중 도 1은 본 발명 역류방지용 댐퍼의 분해사시도이다.1 is an exploded perspective view of the damper for preventing backflow of the present invention.

상기 도면에 의한 본 발명 역류방지용 댐퍼는 안내부재(100)와, 비닐막(200)과, 조각막(300)으로 이루어진다.The damper for preventing backflow of the present invention according to the drawings includes a guide member 100, a vinyl film 200, and an engraving film 300.

구체적으로 상기 안내부재(100)는 링형의 틀체(110)와, 이 틀체(110)의 내부를 따라 방사상으로 형성된 날개(120)들과, 이 날개들(120)이 한곳에 집중되는 중심부(130)로 이루어지고, 그 뒷면에는 고정돌기(140)들이 중심부(130), 틀체(110)의 상,하단에 걸쳐 돌출되어 있다.Specifically, the guide member 100 has a ring-shaped frame 110, wings 120 formed radially along the interior of the frame 110, and the central portion 130 where the wings 120 are concentrated in one place. It is made of, the fixing projections 140 on the back side of the central portion 130, the frame 110 is projected over the upper and lower ends.

비닐막(200)은 원판형의 비닐이며, 중점에서 어느 하나의 직선방향을 따라 대칭인 직선형의 절취공(210)을 형성하며, 절취공(210)의 사이와,상,하방에 각각 고정공(220)을 형성하여서 되며, 상,하절취공(210)을 축으로 두개의 막이 나비날개처럼 접어지거나 펼쳐지게 된다.The vinyl film 200 is a disc-shaped vinyl, and forms a straight cut hole 210 which is symmetrical along any straight direction at the midpoint, and is fixed between the cut holes 210 and above and below, respectively. 220 is formed, and the two membranes are folded or unfolded like a butterfly wing based on the upper and lower cutting holes 210.

따라서 상기 안내부재(100)와 비닐막(200)의 조립은 상기한 안내부재(100)의 후방 소정위치에 고정돌기(140)에 상기 비닐막(200)의 고정공(220)을 끼움으로써조립된다.Therefore, the assembly of the guide member 100 and the vinyl film 200 is assembled by fitting the fixing hole 220 of the vinyl film 200 to the fixing protrusion 140 at the rear predetermined position of the guide member 100. do.

본 발명의 상기 비닐막(200)은 그의 후방 분리를 방지하기 위하여 더 작은 크기의 고정공(310)이 형성된 조각막(300)에 의하여 체결고정된다.즉, 기 조립된 비닐막(200)의 고정공(220)을 통하여 돌출된 안내부재(100)의 고정돌기(140)에 고정공(310)을 끼움으로써 조립이 완성된다.The vinyl film 200 of the present invention is fastened and fixed by the engraving film 300 formed with a smaller fixing hole 310 in order to prevent the rear separation thereof. That is, the pre-assembled vinyl film 200 Assembly is completed by fitting the fixing hole 310 to the fixing protrusion 140 of the guide member 100 protruding through the fixing hole 220.

첨부 도면중 도 2a는 본 발명 역류방지용 댐퍼의 기류흐름이 없는 상태의 작용단면도이며, 도 2b는 본 발명 역류방지용 댐퍼의 기류흐름이 있는 경우의 작용단면도이다.상기 도면에 따르는 본 발명 역류방지용 댐퍼의 작용은 도 2a와 같이 전방에서 기류유입이 없을 때에는 비닐막(200)은 펼쳐진 상태이며, 후방의 기류이동이 있더라도 펼쳐진 상태를 유지한다. 즉, 후방으로 부터 역기류가 발생하면 비닐막(200)은 안내부재(100)의 날개(120)들에 막혀 전방으로의 개방이 차단되어 역기류의 전방이동을 차단하자만 송풍기쪽으로 부터 기류가 유입되면 공회전중인 날개(120)들 사이를 통과하여 비닐막(200)을 후방으로 벌려 두개의 비닐막 개방상태를 유지하게 된다. 이것은 첨부 도면 도 2b에서 도시하는 바와같이 두개의 비닐막이 갖는 연질의 재료특성상 전방 기류의 유입에 따라 구부러지기 때문이다.이후 송풍기쪽의 기류유입이 정지되면 비닐막(200)은 비닐막이 갖는 탄력으로써 원복되어 펼쳐진다.이와같이 본 발명 역류방지 댐퍼의 비닐막은 전방에서의 정상 기류유입시에는 개방작동을 하나, 반대로 내측으로 부터 반대 기류가 발생되면 비닐막(200)은 전방쪽 안내부재의 공회전 날개(120)들에 의하여 막혀 개방이 되지 않는 특징이 있다.이것은 본 발명 역류방지 댐퍼가 설치된 내측으로 부터의 역기류를 외측으로 보내지 않도록 함으로써 기류의 일방향 이동만을 가능하게 하는 경우에 적당한 댐퍼기능을 수행하게 된다.In the accompanying drawings, Figure 2a is a cross-sectional view of the operation of the present invention in the absence of the airflow flow of the damper for preventing the backflow of the present invention, Figure 2b is a cross-sectional view of the action of the airflow of the damper for preventing the backflow of the present invention. When there is no airflow in the front as shown in FIG. 2A, the vinyl film 200 is in an unfolded state and maintains an unfolded state even when there is a rearward air flow. That is, when the back air flows from the rear, the vinyl film 200 is blocked by the wings 120 of the guide member 100 to block the opening of the front air to block the forward movement of the back air, but the air flow from the blower side is blocked. When introduced, the vinyl film 200 is opened to the rear by passing between the blades 120 that are idle and maintain two vinyl film open states. This is because the flexible material characteristic of the two vinyl membranes is bent due to the inflow of the front airflow as shown in FIG. 2B. When the airflow to the blower side is stopped, the vinyl membrane 200 is elastic due to the vinyl membrane. As described above, the vinyl membrane of the backflow prevention damper of the present invention operates in the inflow of normal airflow from the front, but on the contrary, if the opposite airflow is generated from the inside, the vinyl film 200 is the idle blade 120 of the front guide member. This is a feature that is blocked by the () is not opened. This is a damper function is performed in the case of enabling only one-way movement of the air flow by not sending the reverse air flow from the inside in which the present backflow prevention damper is installed to the outside. .

종래 편심축과 고깔모양의 구조를 갖는 댐퍼부재가 갖는 문제점, 즉 외부배출기류의 배기시에는 고깔안쪽을 밀어내어 개도를 개방하고,역류유입시에는 돌출부를 통하여 양연부로만 기류가 흐르도록 하여 완전 차단은 어렵고 일부 기류유입이 이루어지는 구조에 비하여 본 발명 역류방지 댐퍼는 역류의 완전한 차단이 가능한 효과가 있다.아울러 이와같은 기류의 개폐작동을 위하여 사용된 재료가 비닐재의 막이므로 설치단가면에서 저렴한 경제적 효과도 있다.The problem with the conventional damper member having an eccentric shaft and a solid shape, that is, when exhausting the external discharge airflow, pushes the inside of the solid opening to open the opening, and when the inflow flows, the airflow only flows through the protruding portion to the edge. In contrast to the structure in which blocking is difficult and the inflow of some airflow is made, the backflow prevention damper of the present invention has the effect of completely blocking the backflow. It also works.
