선풍기 그릴의 회전 제어장치Fan rotation control

제1도는 본 고안의 단면도.1 is a cross-sectional view of the present invention.

제2도는 제1도 A-A선 단면도.2 is a cross-sectional view taken along the line A-A of FIG.

제3도는 본 고안의 사용예시도.3 is an example of the use of the present invention.

제4도는 본 고안의 정면도.4 is a front view of the present invention.

본 고안은 직사각형 케이스 내부에 선풍기를 장착하여 케이스 전면에 형성된 원형 그릴(grille)로 송풍하게 된 것에 있어서 원형 그릴의 회전축을 액체가 충만된 케이스 내부에 익차와 함께 축설하여 선풍기의 바람에 의하여 원형 그릴이 회전하면서 실내의 사방으로 바람을 보내는 동시 선풍기의 회전속도에 의한 송풍의 강약에 관계 없이 그릴은 거의 일정한 속도로 회전할 수 있게한 선풍기 그릴의 회전 제어장치에 관한 것이다.The present invention is to install a fan inside the rectangular case to be blown by a circular grill (grille) formed on the front of the case in which the rotating shaft of the circular grill is laid in the case filled with liquid with blades of the circular grill by the wind of the fan The rotation control apparatus of the fan grill which enables the grill to rotate at almost constant speed irrespective of the strength or weakness of the blowing due to the rotational speed of the simultaneous fan that sends the wind in all directions in the room while rotating.

종래 케이스 내부에 선풍기가 장착된 것은 고정된 그릴을 통하여 외부로 송풍하게 되어 바람이 그릴의 경사진 안내편의 병렬된 일정방향으로만 송풍되는 결점이 있고 송풍방향을 사방으로 순환시키기 위하여 대형 선풍기의 경우 그릴을 별도의 회전 모우터에 의하여 회전시키게 된 것도 있으나 회전기구가 복잡하고 별도의 동력이 소요되는 비경제적인 결점이 있었다.Conventionally, a fan installed inside the case is blown to the outside through a fixed grill, and the wind is blown only in a parallel direction of the inclined guide piece of the grill, and in the case of a large fan to circulate the blowing direction in all directions The grill was rotated by a separate rotary motor, but there was an uneconomical disadvantage that the rotating mechanism was complicated and required a separate power.

본 고안은 종래의 이러한 결점을 시정하고 선풍기의 바람을 사방으로 확산할 수 있게 하기 위하여 액체탱크 내부에 익차와 증속기어 등을 축설하여 선풍기 케이스의 전면에 유착된 원형 그릴의 회전축을 증속기어축에 접속하여 선풍기의 풍력에 의하여 그릴이 회전되면서 사방에 바람을 확산하는 동시에 선풍기의 회전속도가 빠르게 되어 풍력이 강하게 되면 그릴의 회전속도도 따라서 빠르게 되나 이 때 그릴의 회전축과 연동되는 증속기어의 익차가 회전증가에 상응하여 액체탱크내에서의 유체저항이 크게되어 그릴의 회전속도를 억제시키어 저속으로 회전되고 선풍기의 회전속도가 느려서 풍력이 약하게 되면 그릴의 회전속도도 따라서 느리게 되므로 익차의 액체저항이 보다 감소되어 그릴의 회전이 원활하여서 선풍기의 풍력의 변화에도 그릴의 회전은 거의 균일하여 실내에 균일한 분포로 송풍할 수 있게 안출한 것으로 이를 도면에 의하여 상세히 설명하면 다음과 같다.The present invention corrects these drawbacks of the prior art, and in order to spread the wind of the fan in all directions, the rotor shaft and the gearbox are installed inside the liquid tank, and the rotary shaft of the circular grill adhered to the front of the fan case is connected to the gearbox. When the grill is rotated by the wind power of the fan, the wind spreads in all directions, and the rotation speed of the fan is increased, and when the wind is strong, the rotation speed of the grill is increased accordingly. Corresponding to the increase in rotation, the fluid resistance in the liquid tank is increased, which suppresses the rotational speed of the grille and rotates at low speed. When the wind speed is low due to the slow rotational speed of the fan, the rotational speed of the grille is also slowed down. The rotation of the grille is reduced so that the grille can be rotated even if the wind power of the fan changes. The rotation is almost uniform and can be blown out with a uniform distribution in the room. This will be described in detail with reference to the accompanying drawings.

직사각형의 고정식 케이스(13)의 내부에 모우터(12)로 회전되는 선풍기(11)를 장착하고 케이스(13)의 전면에 원형 그릴(1)을 유착한 것에 있어서 부동액과 같은 액체(3)가 충만된 탱크(4)의 내부에 피니온(7)이 일체로 된 익차(8)를 축설하여 피니온(7)의 축방에는 증속기어(9)를 피니온(7)과 교합되게 축설하고 그릴(1)의 회전축(2)을 전동기어(5)의 지축(6)과 동축으로 연접되게 축설하여 전동기어(5)와 증속 기어(9)에 의하여 익차(8)가 액체 탱크(4)에서 회전하게 된 것이다.In the case where the fan 11 rotated by the motor 12 is mounted inside the rectangular fixed case 13 and the circular grill 1 is adhered to the front of the case 13, a liquid 3 such as an antifreeze solution is formed. Into the inside of the filled tank 4, the blade wheel 8 in which the pinion 7 is integrated is built up, and the gearbox 9 is assembled with the pinion 7 in the axial direction of the pinion 7 and grilled. The rotary shaft 2 of (1) is arranged coaxially with the support shaft 6 of the electric gear 5 so that the blade wheel 8 is driven from the liquid tank 4 by the electric gear 5 and the speed increasing gear 9. It's a turn.

도면중 미설명부호 10은 액체 탱ㅋ의 지지간이다.In the figure, reference numeral 10 denotes the support interval of the liquid tank.

이와 같이된 본 고안은 제3도에 표시한 바와 같이 모우터(12)에 의하여 선풍기(11)가 회전하면 바람은 그릴(1)을 통하여 케이스(13) 외부로 송풍되면서 그릴(1)은 그 풍력에 의하여 공회전하여 선풍기의 바람을 실내사방으로 확산하게 되는 바 선풍기(11)의 회전속도가 빠르게 되어 풍력이 강하면 그릴(1)의 공회전 속도도 자연이 따라서 증가되나 이때 그릴(1)의 회전은 지축(2)에 의하여 전동기어(5)가 회전되고 전동기어(5)와 교합된 피니온(9')과 증속기어(9)가 증속회전하면서 익차(8)의 피니온(7)을 보다 증속 회전시키어 익차(8)는 그릴(1)의 회전속도보다 훨씬 빠르게 회전되면서 액체 탱크(4)내의 액체와의 충돌로 유체저항을 받게되며 이 유체저항을 익차(8)의 회전속도의 완속에 상응하게 증감되므로 선풍기의 풍력이 강하여 그릴(1)의 회전력도 크게되면 익차(8)의 회전저항이 크게되어 크릴(1)의 회전을 억제시키어 저속으로 회전되고 선풍기의 풍력이 약하여서 그릴(1)의 회전력이 저하되면 익차(8)의 회전저항도 적게 되므로 여전히 저속으로 회전되어서 선풍기의 고저속회전에 관계없이 그릴은 거의 일정한 속도로 자동 제어되어 실내 사방에 균일분포로 바람을 확산하게 되고 또한 선풍기의 풍력에 의하여 그릴이 공회동하면서 바람을 확산 송풍할 수 있게 하였기 때문에 종래 별도의 모우터로 회전시켰던 것에 비하여 구조가 간단하고 에너지 소모가 절약되어 보다 경제적으로 편리하게 사용할 수 있는 효과를 가진다.In the present invention as shown in FIG. 3, when the fan 11 is rotated by the motor 12, the wind is blown out of the case 13 through the grill 1, and the grill 1 is When the wind speed of the fan 11 is increased by idling by the wind, the wind speed of the fan is diffused everywhere. If the wind speed is strong, the idling speed of the grill 1 increases according to the nature, but the rotation of the grill 1 The electric gear 5 is rotated by the support shaft 2, and the pinion 9 'and the increase gear 9, which are engaged with the electric gear 5, rotate at a high speed to view the pinion 7 of the vane 8. By increasing the speed of rotation, the vane 8 is rotated much faster than the rotation speed of the grill 1 and is subjected to fluid resistance due to the collision with the liquid in the liquid tank 4, and the fluid resistance is slowed down to the slow speed of the vane 8 rotation. If the wind power of the fan is strong and the rotational force of the grill 1 is large, If the rotational resistance of (8) is large to suppress the rotation of the krill (1) to rotate at low speed, and the wind power of the fan is weak and the rotational force of the grill (1) is lowered, the rotational resistance of the blade (8) is also low, so it is still at low speed. Since the grill is rotated, regardless of the high and low rotation speed of the fan, the grill is automatically controlled at a constant speed to spread the wind in a uniform distribution all around the room, and also by the wind power of the fan, the grill can rotate and blow air. Compared with the conventional motor rotated by a separate motor, the structure is simple and energy consumption is saved, so that it can be used more economically and conveniently.
