본 고안은 원심력 셔터 환풍기의 개량 고안으로 특히, 환풍날개와 개폐날개를 분리시킨 셔터 환풍기를 제공하려는 것이다.The present invention is an improvement of the centrifugal shutter fan, and in particular, to provide a shutter fan that separates the fan blade from the opening and closing wing.
종래 셔터 환풍기는 국내 실용신안 공고 85-6047, 87-2514, 88-1785 등에서와 같이 셔터날개에 겸용되는 환풍날개와, 환풍날개를 로터의 방사축에 조립하고 환풍날개를 닫힌셔터 상태와 환풍상태로 전환조작하는 변환기구와, 로터의 회전시 환풍상태가 되게 하며 반대로 정지시 닫힌 상태로 구동하는 리턴스프링으로 구성한 것이었다.Conventional shutter ventilator is equipped with a vent blade that is combined with the shutter blades, as in the domestic utility model announcements 85-6047, 87-2514, 88-1785, and the vent blade to the radial axis of the rotor and the vent blade is closed shutter and ventilated state It is composed of a converter mechanism for converting and switching to a return spring, which causes a ventilated state when the rotor rotates and, in contrast, drives a closed state when stopped.
이와같은 환풍기는 환풍날개가 셔터날개에 겸용되기에 환풍효율과 개폐기능을 동시에 만족하는 최적 설계가 어려운 것이어서, 환풍효율이 감소되고 셔터의 개폐동작시 원심기구의 동작 충격음이 발생하며 환기구 차단상태가 불량한 등의 문제점을 가지는 것이었다.Such a ventilator is difficult to design optimally to satisfy both the ventilation efficiency and the opening / closing function at the same time because the ventilation blades are combined with the shutter blades. It was to have a problem such as poor.
본 고안은 이와같은 문제점을 개선한 고안으로, 환풍날개와 셔터 날개를 분리 구성하여 환풍효율과 셔터 기능을 최적화 하며, 셔터의 개폐동작이 정숙 원활하게 이루어질고, 환풍동작시 모터의 구동축을 셔터 기구와 분리시켜 환풍모터의 부하를 최소화 하게한 것으로, 본 고안은 환풍날개를 가지는 환풍모터, 환풍모터의 연장축에 장치되고 원심력으로 진퇴동작하여 셔터구동기구를 동작시키는 셔터조작기구, 셔터 조작기구의 진퇴동작에 대응동작하여 방사상 개폐용 개폐날개를 동작시키는 셔터구동기구, 및 셔터하우징 독립된 개폐날개를 방사상으로 배열하여 환풍구를 개폐하는 개폐기구로 구성함을 특징으로 하는 것으로 첨부도면에 따라서 상세하게 설명하면 다음과 같다.The present invention improves the above problems, and separates the ventilation blades and the shutter blades to optimize the ventilation efficiency and the shutter function, the operation of opening and closing the shutter is made smoothly, and the drive shaft of the motor during the ventilation operation In order to minimize the load of the vent motor, the present invention provides a vent motor having a vent vane, a shutter operating mechanism which is installed on an extension shaft of the vent motor and moves the shutter drive mechanism by centrifugal force to move the shutter driving mechanism. According to the accompanying drawings, characterized in that it comprises a shutter drive mechanism for operating the radial opening and closing wings in response to the advance and backward operation, and an opening and closing mechanism for opening and closing the ventilation opening by arranging the independent opening and closing of the shutter housing. As follows.
환풍구(1)가 형성된 프레임(2)에 지지되며 환풍날개(3)를 가지는 환풍모터(4); 환풍모터(4)의 연장축(6)에 회전축(7)을 연결하고, 회전아암(8)의 장공(9)에 구비한 원심추(10)와 회전축(7)에 의지시킨 진퇴캡(11)을 링크(12)로 연결하며, 동시에 회전축(7) 외단에 진출스프링(13)과 스토퍼(14)를 구비한 셔터조작기구(15); 셔터하우징(19)의 중심지축(20)에 닫기스프링(21)을 내장한 진퇴부재(22) 중심의 미끄럼지지체(23)를 의지시키고, 진퇴부재(22)의 외륜(24)에 방사상으로 치구(25)를 배열하고 개폐치차(26)를 결합시킨 셔터구동기구(27); 상기 치구(25)에 대응하는 셔터하우징(19)측 보스(31)에 환풍구(1) 개폐용 개폐날개(32)의 회동축(33)을 의지시키고 동시에 회동축(33)을 상기 개폐치차(26)에 부착한 개폐기구(34)를 구성하였고,진퇴캡(11)외단에 진퇴부재(22)의 가압돌기(35)를 구성하여 환풍기가 정상속도로 회전할때 가압돌기(35)는셔터하우징(19)과 분리되게 하며, 진출스프링(13)의 압력을 닫기스프링(21)의 압력보다 크게 하였다.A ventilation motor 4 supported by the frame 2 on which the ventilation holes 1 are formed and having a ventilation wing 3; A revolving cap 11 connected to the extension shaft 6 of the ventilation motor 4 to the centrifugal weight 10 and the rotation shaft 7 provided in the long hole 9 of the rotation arm 8. The shutter operating mechanism 15 having a spring 12 and a stopper 14 connected to the outer side of the rotary shaft 7 at the same time; The sliding support 23 in the center of the retracting member 22 having the closing spring 21 embedded therein is relied on the central axis 20 of the shutter housing 19, and the outer ring 24 of the retracting member 22 is radially jagged. A shutter driving mechanism 27 in which 25 is arranged and the opening and closing gear 26 is coupled; The rotating shaft 33 of the opening / closing blade 32 for opening / closing the ventilation opening 1 is relied on the shutter housing 19 side boss 31 corresponding to the jig 25, and at the same time, the rotating shaft 33 is opened and closed. 26) the opening and closing mechanism 34 attached thereto, and the pressing protrusion 35 of the pressing member 22 is formed at the outer end of the pressing cap 11 so that the pressing protrusion 35 is shuttered when the fan is rotated at a normal speed. The pressure of the outgoing spring 13 was greater than the pressure of the closing spring 21 to be separated from the housing 19.
이와같이 구성된 본 고안은 환풍날개(3)와 개폐날개(32)가 분리되어 있어 각각 그 기능에 따른 최적 설계가 용이하므로 환풍효율과 개폐효율을 높일 수 있는 것이다.The present invention configured as described above has the ventilation wing 3 and the opening and closing wing 32 are separated, so that the optimum design according to their respective functions is easy to increase the ventilation efficiency and opening and closing efficiency.
환풍기가 정지상태에서 셔터 조작기구(15)는 제 4 도의 (a)도와 같이, 진출스프링(13)의 압력이 가압돌기(35)를 통해 진퇴부재(22)를 가압하므로 닫기스프링(21)은 수축되고 중심지축(20)을 따라 외측으로 밀려있는 진퇴부재(22)의 치구(25)는 개폐치차(26)를 회동시켜 보스(31)에 의지된 개폐날개(32)는 제 3 도와 같이 닫힌상태가 되는 것이다.When the fan is stopped, the shutter operating mechanism 15 closes the spring 21 because the pressure of the advance spring 13 presses the retreating member 22 through the pressing projection 35 as shown in FIG. The jig 25 of the retracting member 22, which is contracted and pushed outward along the central axis 20, rotates the opening and closing gear 26 so that the opening and closing wing 32 relied on the boss 31 is closed like a third degree. It becomes a state.
환풍기가 구동되어 연장축(6)이 회전되면 셔터조작기구(15)는 진퇴캡(11)을 후진시켜 제 4 도의 (b)도와같이 가압돌기(35)를 셔터구동기구 (27)에서 분리시킨다.When the fan is driven and the extension shaft 6 is rotated, the shutter operating mechanism 15 reverses the retreat cap 11 to separate the pressing projection 35 from the shutter driving mechanism 27 as shown in FIG. .
환풍기의 완속 회전시 가압돌기(35)는 셔터조작기구(15)와 셔터구동기구(27)간의 마찰을 최소화시켜 준다. 아암(8)의 회전시 원심추(10)에 작용하는 원심력은 원심추(10)를 장공(9)내에서 이동시켜 진출스프링(13)을 누르면서 진퇴캡(11)을 후진시키고,원심추(10)의 원심력이 소멸되면 진출스프링(13)이 원심추(10)를 원위치로 복귀시키고 진퇴캡(11)을 전진시키는 것이다.When the fan rotates slowly, the pressing protrusion 35 minimizes the friction between the shutter operating mechanism 15 and the shutter driving mechanism 27. The centrifugal force acting on the centrifugal weight 10 during the rotation of the arm 8 moves the centrifugal weight 10 in the long hole 9 to reverse the retreat cap 11 while pressing the advance spring 13 and the centrifugal weight ( When the centrifugal force of 10) is extinguished, the advance spring 13 returns the centrifugal weight 10 to its original position and advances the retraction cap 11.
상기 셔터조작기구(15)에서 분리되는 셔터구동기구(27)는 닫기스프링(21)의 압력으로 진퇴부재(22)를 중심지축(20)상에서 이동시키는 것이며, 이동작에서 외륜(24)상의 치구(25)들이 개폐치차(26)를 회전시키고, 개폐치차(26)는 회동축(33)이 보스(31)에 의지된 개폐날개(32)들을 동시에 회동시켜 환풍구(1)를 개방하게 되는 것이다.The shutter drive mechanism 27 separated from the shutter operation mechanism 15 moves the retraction member 22 on the central axis 20 by the pressure of the closing spring 21, and the jig on the outer ring 24 in the movement. (25) rotate the opening and closing gear 26, the opening and closing gear 26 is to rotate the opening and closing blades 32, the rotation shaft 33 is dependent on the boss 31 at the same time to open the vent (1). .
환풍기가 회전상태에서 정지상태로 되면 제 4 도의 (b)도에서 (a)도와같은 상태가 되는 것으로 진퇴캡(11)의 가압돌기(35)가 진출스프링(13)의 압력으로 닫기스프링(21)을 누르면서 진퇴부재(22)를 이동시켜 치구(25)들이 개폐치차(26)를 상기와는 반대로 회전시키고 이 동작으로 개폐날개(32)들이 동시에 회동되어 환풍구(1)를 닫게 되는 것이다.When the ventilator is stopped in the rotating state, the pressure projection 35 of the retraction cap 11 is closed by the pressure of the advance spring 13 as shown in FIG. 4 (b) in FIG. While moving the retreat member 22 while pressing), the jig 25 rotates the opening and closing gear 26 as opposed to the above, and the opening and closing wings 32 are rotated at the same time to close the ventilation opening 1.
상기와 같이 본 고안은 환풍날개와 셔터 날개를 분리 구성하여 환풍효율과 셔터 기능을 최적화하며, 셔터의 개폐동작이 정숙원활하게 이루어지고, 환풍동작시 모터의 구동축을 셔터기구와 분리시켜 환풍모터의 부하를 최소화 하게한 환풍기를 제공하게 된 것이다.As described above, the present invention separates the ventilation blades and the shutter blades to optimize the ventilation efficiency and the shutter function, and smoothly opens and closes the shutter, and separates the driving shaft of the motor from the shutter mechanism during the ventilation operation. It provides a ventilator that minimizes the load.
