본 고안은 환풍기에 있어서 별도의 환기 차단용 샷타를 설치할 필요가 없이 날개판이 원심력에 의해 그 각도가 변화되게 하여 환풍기의 작동시에는 환풍구가 개방되어 환풍되게 하고, 환풍기의 정지시에는 별도의 조작을 필요로 함이 없이 날개판이 서로 맞닿아 환풍구를 차단되게 한 날개판의 각도가 변화되게한 환풍기에 관한 것이다.The present invention does not need to install a separate ventilating shotgun in the ventilator so that the angle of the wing plate is changed by centrifugal force so that the vent opening is open when the ventilator is operating, and a separate operation when the ventilator is stopped. It is related with the fan which the wing plates contacted each other without need and the angle of the wing plate which blocked the vent opening was changed.
종래 환풍기는 건물벽 등의 적당한 위치에 설치하여 실내의 탁한 공기를 바깥으로 내뿜거나 외부공기를 유입하여 실내의 공기를 정화하는 것이나 환풍기의 날개는 그 통풍 간격인 환풍통로가 형성되어 있어서 그 회전이 정지되는 시간에는 그 환풍통로로 외부의 해충이 내부로 침입하거나 실내의 난방 또는 냉방온도를 외부로 빼았겼던 것이어서 이를 해결하기 위해 환기차단용 샷타를 별도로 설치하여 이를 개폐조작하게 한 것과, 환풍기의 날개를 겹치게 형성하여 회전시에는 환풍구를 개방하고 정지시에는 날개판에 의해 환풍구가 패쇄되게 한 것등이 있으나, 전자는 환풍기의 작동시 송풍되는 공기가 샷타에 부딪히게 되어 환풍에 장애가 되며 샷타를 별도로 조작하여야 되는 번거로움과 함께 오랜기간 사용하면 먼지 등에 의해 컬타가 꼭 닫히지 않는 등 여러 문제점이 있었으며, 후자는 환풍구를 완전히 차단하여 주지 못하고 날개판끼리의 충돌에 의해 소음이 많고 파손이 잦을 뿐 아니라 비교적 에너지 소모가 많은 결점이 있었다.Conventionally, the fan is installed at a proper position such as a building wall to blow out the muddy air in the room or to purify the air from the outside by inflowing the outside air. At the time of stopping, the outside passage invaded into the ventilation passage or the heating or cooling temperature of the room was subtracted to the outside. To solve this problem, the ventilator was separately installed to open and close the ventilator. In the case of rotation, the vent opening is opened and the vent opening is blocked by the wing plate when the rotation is stopped. However, in the former case, the blown air hits the shota during operation of the fan, which impedes the ventilation and separates the shotta. If you use it for a long time with the trouble of operation, the culter will be closed tightly by dust. Has had several problems, such as the latter not only does not completely block the vents lot of noise by the collision between the blade breakage jateul had a drawback that a relatively large energy consumption.
본 고안은 환풍기에 있어서, 전기한 바와 같은 결점을 제거코저 별도의 샷타나 중첩용 날개를 필요로 하지 않아 번거로움이나, 소음이 없이 원심력에 의해 환풍기의 날개판의 각도가 변화되게 하여 환풍기가 작동하지 아니할 때는 환풍기의 날개가 수평으로 서로 맞닿아 환풍구를 차단시키고 작동시는 환풍기의 날개가 경사지게 환풍구를 형성하여 환풍되게 한 것으로서, 본 고안의 요지를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention eliminates the above-mentioned defects in the fan, and does not require a separate shot or overlapping blade, so that the angle of the wing plate of the fan is changed by centrifugal force without any hassle or noise. If not, the wings of the fans are in contact with each other horizontally to block the vents, and during operation, the wings of the fans are inclined to form a vent to be inclined, ventilated as described in detail by the accompanying drawings the subject matter of the present invention.
통상의 환풍기 모우터(1)의 회전축(2)에, 원주벽의 상단에 축계지홈(3)(3')이 형성되고 중앙에 축파이프(4)가 돌설되어 형성된 회전원통(5)을 그 축파이프(4)로서 삽착하되, 중앙의 축파이프(4)에는 고정구(6)를 지지스프링(7)으로 탄설하고 그 양측에 회동평(8)(8')을 축설하여 대각선 방향의 스프링(9)(9')으로 탄설하되, 그 일측의 외단부(8a)는 무게추(10)를 설착하고 그 타측의 내단부(8b)는 요동원반(11)에 괘지되게 하며, 축계지홈(3)(3')에는 계지부(12)가 형성된 날개판(13)의 회전축(14)을 삽착계지하고 그 계지부(12)에는 ㄱ자 회동봉(15)을 형성하여 전기한 요동원반(11)의 안내홈(16)에 유삽되게 한 것이다.On the rotating shaft 2 of the normal fan motor 1, the shaft stop grooves 3, 3 'are formed at the upper end of the circumferential wall, and the rotating cylinder 5 formed by the projection of the shaft pipe 4 in the center thereof is formed. The shaft pipe 4 is inserted into the shaft pipe 4, and the center shaft pipe 4 is fastened with a fastener 6 with a support spring 7, and the rotating flats 8, 8 'are laid on both sides thereof, and the springs in a diagonal direction. (9) (9 '), but the outer end portion (8a) of one side is installed the weight (10) and the inner end portion (8b) of the other side to be hung on the swinging disc (11), shaft bearing groove (3) (3 ') the rotation disc 14 of the wing plate 13 formed with the locking portion 12 is inserted and stopped, and the locking portion (12) to form a swing bar (15) to form a swing disk ( 11) is guided to the guide groove (16).
미설명부호 17은 보호캡, α는 날개판의 각도가 변화된 경사각이다.Reference numeral 17 is a protective cap, α is the angle of inclination of the wing plate is changed.
이상과 같은 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention as described above in detail.
본 고안의 환풍기가 그 작동을 하지 않고 멈추어 있을 시에는 제3도(a)의 도시와 같이 고정구(6)와 양측의 회동편(8)(8')에 탄설되어 있는 스프링(9)(9')의 탄력으로 회동편(8)(8')의 일측외단부(8a)가 내측으로 잡아 당겨지므로 회동편(8)(8')의 내단부(8b)가 화살표의 방향과 같이 외측으로 밀려 이에 의해 작동되는 요동원반(11)이 역시 화살표 방향인 앞쪽으로 밀리게 되어 요동원반(11)의 안내홈(16)에 유삽되어 있는 ㄱ 자 회동봉(15)의 회전으로 회전축(14)을 중심으로 날개판(13)의 각이 변화되어 제4도(a)의 도시와 같이 서로 일렬로 맞닿아 환풍구를 차단되게 하는 것으로 별도로 개폐샷타를 닫는 등의 번거로움이 없이 실내외의 공기를 차단하여 실외의 해충이 실내로 유입됨을 막음은 물론 난방 또는 냉방시에 실내의 온도를 외부로 빼앗기지 않는 것이다.When the ventilator of the present invention is stopped without its operation, springs 9 and 9 are installed in the fixture 6 and the rotating pieces 8 and 8 'on both sides as shown in FIG. Since one side outer end 8a of the rotating piece 8, 8 'is pulled inward by the elasticity of'), the inner end 8b of the rotating piece 8, 8 'is moved outward in the direction of the arrow. The swing disk 11, which is pushed and operated by this, is pushed forward, which is also the direction of the arrow, and rotates the rotating shaft 14 by the rotation of the a-shaped pivot rod 15 inserted in the guide groove 16 of the swing disk 11. By changing the angle of the wing plate 13 to the center to contact with each other in a line as shown in Fig. 4 (a) to block the air vents to block the air outside the indoor and outdoor without the hassle of closing the opening and closing shot In addition to preventing the introduction of outdoor pests into the room, it does not take the temperature of the room to the outside during heating or cooling.
또한 실내의 공기가 혼탁하여져 환기를 시킬 필요가 있을 때에는 별도의 개폐샷타 등의 조작이 필요없이 전원만을 연결시켜 주면 환풍기의 모우터(1)가 회전을 시작하면서 모우터(1)의 회전축(2)에 삽착되어 있는 회전원통(5)을 회전시키게 되고 이 회전원통(5)의 축파이프(4)에 지지스프링(7)으로 탄설되어 있는 고정구(6)가 회전되면서 제3도(b)의 도시와 같이 고정구(6)와 스프링(9)(9')으로 탄설되어 있는 회동편(8)(8')의 일측외단부(8a)에 설착되어 있는 무게추(10)가 따라 회전하게 되고 회전함에 따라 생기는 무게추(10)의 원심력에 의해 무게추(10)가 밖으로 벗어나려는 힘이 고정구(6)와 회동편(8)(8')을 잡아당겨 주는 스프링(9)(9')의 힘보다 크게 될 때 회동편(8)(8')을 회동편(8)(8')의 외단부(8a)가 제3도(b)의 화살표 방향인 외측으로 벌어지면서 요동원반(11)에 괘지되어 있는 회동편(8)(8')의 타측내단부(8b)가 내측으로 당겨져 이에 의해 요동원반(11)을 화살표 방향인 내측으로 당겨지게 하여 요동원반(11)의 안내홈(16)에 유삽되어 있는 ㄱ자회동봉(15)이 회전원통(5) 원주벽 상단의 축계지홈(3)(3')에 삽착계지되어 있는 회전축(14)을 중심으로 회동되고 이에 따라 날개판(13)이 제4도(b)의 도시와 같이 회동봉(15)의 회동각도만큼 일정하게 각변화하여 경사각(α)을 이룸으로서 그 경사각(α)에 의해 환풍구를 형성시킴과 동시에 날개판(13)의 경사각도에 의해 실내의 공기를 환풍되도록 한 것이다.In addition, when the air in the room becomes cloudy and needs to be ventilated, if only the power supply is connected without the need for a separate opening and closing shot, the motor 1 of the fan starts rotating and the rotating shaft of the motor 1 rotates. Rotating the rotary cylinder (5) inserted in the) and the fixture 6, which is installed as a support spring (7) in the shaft pipe (4) of the rotary cylinder (5) is rotated as shown in FIG. As shown in the figure, the weight 10 installed on one side outer end 8a of the pivoting piece 8, 8 ', which is installed by the fixture 6 and the spring 9, 9', is rotated along. Spring (9) (9 ') that pulls the fixture (6) and the rotating piece (8) (8') by the force that the weight (10) is out of the way by the centrifugal force of the weight (10) generated by the rotation When it becomes larger than the force of the swinging piece 8, 8 ', the outer end 8a of the rotating piece 8, 8' opens outward in the direction of the arrow in FIG. Hanging on The other inner end portion 8b of the pivoting piece 8, 8 'is pulled inward, thereby causing the swinging disc 11 to be pulled inwardly in the direction of the arrow to the guide groove 16 of the swinging disc 11. The inserted A-shaped rotating rod (15) is rotated about the rotating shaft (14) inserted and stopped in the shaft stop groove (3) (3 ') of the upper end of the circumferential wall (5) and thus the wing plate (13). As shown in FIG. 4 (b), the angle is changed at a constant angle by the rotation angle of the rotation rod 15 to form an inclination angle α, thereby forming a vent hole by the inclination angle α and at the same time the wing plate 13 The angle of inclination of the air in the room was to be ventilated.
또한 그 동작을 멈출시는 회전의 정지에 의해 전기한 원심력이 없어지므로 다시 자동적으로 스프링(9)(9')의 탄력으로 전기한 바와 같이 회동편(8)(8')을 원위치시켜 날개판(13)을 역시 원래의 수평상태로 변화하여 서로 맞닿게 되므로서 환풍구를 막아주어 실내외의 공기를 차단하는 것이다.In addition, since the centrifugal force transmitted by the rotation stops when the operation is stopped, the rotating pieces 8 and 8 'are repositioned as shown in the springs 9 and 9'. (13) is also changed to the original horizontal state to be in contact with each other to block the air vents to block the indoor and outdoor air.
이상과 같이 본 고안은 환풍기에 별도의 개폐샷타를 장착할 필요가 없어 구조가 간단할 뿐 아니라 환풍기의 작동시에 개폐샷타를 별도로 조작하여야 되는 번거로움이 없이 스스로 원심력에 의해 날개판이 개폐작동되게 한 매우 유용한 고안이라 하겠다.As described above, the present invention does not need to install a separate opening and closing shotgun in the ventilator, and the structure is simple, and the wing plate is opened and closed by centrifugal force by itself without the hassle of operating the opening and closing shotta separately during the operation of the fan. It is a very useful design.
