본 발명은 환풍기에 관한 것으로 더욱 구체적으로는, 환풍기 양측에 개폐문을 가진 배기부를 형성하여 우수한 환기 성능을 보장함과 동시에 환풍기의 미작동시 배기부를 차단하여 외부의 각종 이물질이나 먼지, 곤충 등이 환풍기 내부로 유입되는 것을 방지할 수 있게 한 환풍기에 관한 것이다.The present invention relates to a ventilator, more specifically, to the exhaust vents having opening and closing doors on both sides of the ventilator to ensure excellent ventilation performance and at the same time shut off the exhaust vent when the ventilator is not in operation, various foreign substances, dust, insects, etc. It relates to a ventilator that can be prevented from entering inside.

일반적으로 환풍기는 건물 내부의 공기를 외부로 내보내기 위해 설치하는 것으로서, 일반 주택 뿐만 아니라 비닐하우스, 공장 건물 등에서 많이 설치된다.In general, the ventilator is installed to export the air inside the building to the outside, and is installed in a plastic house, a factory building, as well as a general house.

이러한 환풍기의 일반적인 구성을 간략히 설명하면, 모터에 의해 회전하는 팬이 설치되는 본체와, 건물 내부 공기를 흡입하는 흡기부 및 흡입된 건물 내부 공기를 배출하는 배기구 및 배기구를 개폐하는 개폐문으로 구성된다.Briefly describing the general configuration of the fan, the fan is composed of a main body that is installed by the rotating fan, an intake unit for sucking the air inside the building, and an exhaust port for discharging the intake air inside the building and the opening and closing door for opening and closing the exhaust port.

그리하여 환풍기가 작동할 때는 개폐문을 열고, 환풍기를 작동하지 않을 때는 개폐문을 닫아서 외부의 각종 먼지나 이물질, 벌레 등이 환풍기를 통해 건물 내부로 유입되는 것을 방지하게 되는데, 종래의 일반적인 환풍기는 개폐문의 개폐 구조가 환풍기의 팬에 의해 발생한 바람의 힘에 의해 여닫히는 구조로 되어 있어서, 개폐문의 개폐 작동시 작동의 신뢰성이 떨어질 뿐만 아니라, 외풍이 심한 경우에는 팬이 작동하더라도 개폐문이 열리지 않는 경우도 빈번히 발생하는 문제점이 있었다.Thus, when the ventilator is operating, the opening and closing door is opened, and when the ventilator is not operating, the opening and closing door is closed to prevent various dusts, foreign substances, and insects from entering the building through the ventilator. As the structure is opened and closed by the force of wind generated by the fan of the fan, the operation reliability of the opening and closing doors is not only decreased, and in the case of heavy drafts, the opening doors do not open even if the fan is operated. There was a problem.

본 발명은 위와 같은 종래의 불편을 해소하기 위하여 안출한 것으로서, 본 발명의 목적은 우수한 환기 성능을 보장함과 동시에 개폐문의 정확한 개폐가 이루어질 수 있게 하여 환풍기의 작동 신뢰성을 크게 향상시키는 데 있다.The present invention has been made to solve the above conventional inconveniences, the object of the present invention is to ensure an excellent ventilation performance and at the same time to accurately open and close the opening and closing door to significantly improve the operation reliability of the fan.

이하, 본 발명의 바람직한 실시 예를 첨부된 도면에 의하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

첨부도면 도 1은 본 발명의 사시도이며, 첨부도면 도 2는 본 발명의 정면 단면 예시도로서, 도면과 같이 본 발명의 본체(10)는 하부에 흡기부(20)를 형성하고 상부 양 측면에 배기부(30)를 형성한 구조로 이루어진다.Figure 1 is a perspective view of the present invention, Figure 2 is a front cross-sectional view of the present invention, as shown in the main body 10 of the present invention to form an intake portion 20 in the lower and the upper both sides It has a structure in which the exhaust unit 30 is formed.

또한, 본체(10) 상부에는 모터(40)가 설치되어 보호커버로 덮여 있으며, 모터(40)의 회전축(601)은 본체(10) 내부로 투입되어 그 단부에 팬(50)을 설치하게 된다.In addition, the motor 40 is installed above the main body 10 and covered with a protective cover, and the rotating shaft 601 of the motor 40 is introduced into the main body 10 to install a fan 50 at an end thereof. .

그리하여 팬(50)이 회전하면 흡기부(20)를 통해 공기를 흡입하여 본체(10) 양측의 배기부(30)를 통해 배출하게 된다.Thus, when the fan 50 rotates, the air is sucked through the intake unit 20 and discharged through the exhaust unit 30 on both sides of the main body 10.

또한, 본체(10) 양 측면에 형성된 배기부(30) 내측에는 개폐문(60)을 설치하게 되는데, 개폐문(60)은 하부에 회전축(601)을 설치하여 회전 가능케 하되, 회전축(601)에는 비틀림스프링(602)을 설치하여, 비틀림스프링의 일단부는 본체(10)의 내벽 일측에 고정하고, 비틀림스프링의 타단부는 개폐문(60)과 고정함으로써, 첨부도면 도 3과 같이 비틀림스프링(602)의 장력에 의해 개폐문(60)은 자동으로 개방된다.In addition, an opening and closing door 60 is installed inside the exhaust unit 30 formed on both sides of the main body 10, and the opening and closing door 60 is rotatable by installing a rotating shaft 601 at a lower portion thereof, and twisting the rotating shaft 601. By installing a spring 602, one end of the torsion spring is fixed to one side of the inner wall of the main body 10, and the other end of the torsion spring is fixed to the opening and closing door 60, as shown in Figure 3 of the torsion spring 602 The door 60 is automatically opened by the tension.

한편, 본체(10)의 일측면에는 개폐수단을 설치하여 개폐수단에 의해 개폐문(60)을 강제로 개폐할 수 있게 되는데, 첨부도면 도 4에서 도시한 바와 같이 본체(10) 일측 외벽에는 모터(701)에 의해 회전하는 릴(70)을 설치하여 본체(10) 양측의 배기부(30) 내측에 각각 설치된 개폐문(60)과 본체(10) 외벽에 설치된 릴(70)을 와이어(702)로 연결하여 모터(701)를 이용해 릴(70)을 회전시키면 릴(70)에 와이어(702)가 감기거나, 감겨있던 와이어(702)가 풀릴(70) 수 있게 구성함으로써, 릴(70)을 회전시켜 와이어(702)를 감으면, 와이어(702)가 당겨지면서 와이어(702)가 연결된 개폐문(60)도 당겨져 배기부(30)를 닫게 된다.On the other hand, one side of the main body 10 is provided with the opening and closing means to be able to open and close the opening and closing door 60 by the opening and closing means, as shown in Figure 4, the outer wall of the main body 10, the motor ( The reel 70 rotated by the 701 is installed to open and close the door 60 and the reel 70 provided on the outer wall of the main body 10, respectively, on the inside of the exhaust unit 30 on both sides of the main body 10, with the wire 702. When the reel 70 is rotated by using the motor 701, the wire 702 is wound around the reel 70, or the wire 702 that is wound is configured to be loosened 70, thereby rotating the reel 70. When the wire 702 is wound around the wire 702, the wire 702 is pulled and the opening / closing door 60 to which the wire 702 is connected is also pulled to close the exhaust unit 30.

반면에 릴(70)을 회전시켜 감겨있던 와이어(702)를 풀어주면, 개폐문(60)과 릴(70) 간의 와이어(702)가 느슨해짐과 동시에 개폐문(60)의 회전축(601)에 설치된 비틀림스프링(602)의 복원력이 개폐문(60)에 작용하여 개폐문(60)이 자동으로 열리면서 배기부(30)가 개방되기 때문에 환풍기에 의한 환기가 이루어질 수 있게 된다.On the other hand, when the reel 70 is rotated to release the wound wire 702, the wire 702 between the opening and closing door 60 and the reel 70 is loosened and at the same time, the torsion installed in the rotating shaft 601 of the opening and closing door 60. Since the restoring force of the spring 602 acts on the opening / closing door 60, the exhaust door 30 is opened while the opening / closing door 60 is automatically opened, thereby allowing ventilation by the fan.

한편, 첨부도면 도 5와 같이 개폐문(60)과 릴(70) 간을 연결한 와이어(702)에는 가이드(703)를 따라 이동하는 스위치블럭(704)을 고정하며, 스위치블럭(704)의 이동 경로에는 회전레버(705)를 설치하고, 그 하부에는 리미트스위치(706)와 받 침대(707)를 부설함으로써, 스위치블럭(704)이 릴(70) 쪽으로 이동하면 스위치블럭(704)에 의해 회전레버(705)가 회전하면서 받침대(707)에 거치된 리미트스위치(706)의 레버(705)를 가압하면, 레버(705)가 휘어지면서 리미트스위치(706)의 OFF시킴으로써, 릴(70)을 회전시키는 모터(701)의 자동을 정지시켜, 개폐문(60)의 개폐를 담당하는 모터(701)의 작동을 제어할 수 있게 된다.Meanwhile, as shown in FIG. 5, the switch block 704 moving along the guide 703 is fixed to the wire 702 connecting the opening / closing door 60 and the reel 70, and the switch block 704 moves. The rotary lever 705 is installed in the path, and the limit switch 706 and the support 707 are installed in the lower part thereof. When the switch block 704 moves toward the reel 70, the switch block 704 rotates. When the lever 705 is rotated and the lever 705 of the limit switch 706 mounted on the pedestal 707 is pressed, the reel 70 is rotated by turning off the limit switch 706 while the lever 705 is bent. By automatically stopping the motor 701, the operation of the motor 701 in charge of opening / closing the opening / closing door 60 can be controlled.

이상에서 설명한 바와 같이 본 발명은 환풍기의 배기부를 본체 상부 양측에 형성하고, 그 내부에는 모터와 비틀림스프링의 힘에 의해 개폐되는 개폐문을 설치하여 개폐문이 개폐가 정확히 이루어지도록 함으로써, 환풍기 작동의 신뢰성을 향상시킬 수 있을 뿐만 아니라, 다중 배기구에 의한 환기 성능을 향상시킬 수 있는 이점이 있다.As described above, according to the present invention, the exhaust parts of the fan are formed on both sides of the upper part of the main body, and an opening / closing door which is opened and closed by the force of the motor and the torsion spring is installed in the inside thereof so that the opening / closing door can be precisely opened and closed, thereby improving the reliability of the fan operation. Not only can it be improved, there is an advantage that can improve the ventilation performance by multiple exhaust ports.
