본 고안은 선풍기의 수진속도 조절장치에 관한 것으로, 특히 별도로 수진속도 조절을 위한 모우터를 사용하지 않고 다수단의 스퍼어기어를 이용하여 수진속도를 조절할 수 있도록 한 선풍기의 수진속도 조절장치에 관한 것이다.The present invention relates to a water speed control device of the fan, and more particularly to a water speed control device of the fan to adjust the water speed using a multi-stage spur gear without using a motor for water speed control separately. will be.
종래 선풍기의 수진장치는 제6도에서 보인 바와같이, 모우터축(1)에 구동기어(2)를 통하여 전동축(3)을 결합하고 이 전동축(3)에 착설된 기어(4)를 단일 스퍼어기어(5)에 연결하여 크랭크축(6)을 통해 크랭크(7)를 작동케하므로서 수진이 이루어지도록 하였으며, 전동축(3)에는 수진기구버튼(8)을 역하여 이 수진기구버튼(8)을 승강시키므로서 기어(4)가 스퍼어기어(5)에 결합분리되게 하여 수진작동이 이루어지도록 하였다.As shown in FIG. 6, a conventional electric fan of a fan is coupled to a motor shaft 1 through a drive gear 2 through a drive shaft 2, and the gear 4 mounted on the drive shaft 3 is unified. It is connected to the spur gear (5) to operate the crank (7) through the crankshaft (6) so that the dust is made. By elevating 8), the gear 4 was separated from the spur gear 5 so that the water-repellent operation was performed.
그러나 이는 수진속도가 일정하게 되는 형태이므로 수진속도를 가변적으로 조절하기 위한 제안이 있었다.However, since this is a form in which the water velocity becomes constant, there has been a proposal to variably adjust the water velocity.
그 한가지 제안의 형태로서는 수진기구를 별도의 모우터에 연결하여 모우터의 가변속도에 따라서 수진속도가 조절되도록 하였으나 이는 부가적으로 고가의 모우터가 사용되어야 하며 이에 부속되는 다수의 부품이 사용되어야하므로 제품의 원가면에 불리한 점이 있었다.In one form of proposal, the oscillation mechanism is connected to a separate motor so that the oscillation speed can be adjusted according to the variable speed of the motor, but additionally, an expensive motor should be used and a number of parts attached thereto should be used. Therefore, there was a disadvantage in the cost of the product.
본 고안에 있어서는 종래의 이와같은 점을 감안하여 안출한 것으로 별도로 수직속도 조절을 위한 모우터를 사용하지 않는 형태의 수진속도 조절장치를 제공하는데 그 목적이 있는바, 이를 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention has been made in view of such a conventional point of the present invention is to provide a water speed control device of the type that does not use a motor for the vertical speed adjustment separately, based on the accompanying drawings in more detail The explanation is as follows.
제1도 내지 제5도에 도시된 바와같이 모우터축(11)의 단부에 수개의 방사상 종요홈(12)을 갖는 축공(13)을 형성하여 압축스프링(14)을 내장하고 방사상 종요홈(12)에 결합되는 방사상돌기(15)를 갖는 전동축(16)의 단부를 모우터축(11)의 축공(13)에 삽입하며, 전동축(16)의 타측단부에는 전면중앙에 안내홈(17)을 갖는 평기어(18)를 착설하고, 수진을 위한 크랭크(19)가 착설된 크랭크축(20)에 구동푹(21)을 결합하여 이에 착설된 스퍼어기어(22)가 평기어(18)에 교합되게 한 것에 있어서, 크랭크축(20)에 수개의 방사상 종요홈(23)을 갖는 축공(24)이 형성된연결캡(25)을 착설하여 축공(24)에 인장스프링(26)을 내장하고 구동축(21)의 하단에 수개의 방사상돌기(27)를 형성하여 연결캡(25)에 연결하며, 스퍼어기어(22)는 대중소기어(22a)(22b)(22c)로 구성되는 다단의 형태로 구동축(21)에 착설하고, 구동축(21)의 상단부는 제1견인 와이어(28)로 축(29)으로 축설된 레바(30)의 일단에 연결하며, 레바(30)의 타단은 경사측면(31)을 갖는 속도조절판(32)에 제2견인 와이어(33)로 연결하고 속도 조절판(32)의 하단은 제3견인와이어(34)로 좌판(도시하지 않았음)에 착설된 작동버튼(35)에 연결하며, 평기어(18)와 속도조절판(32) 사이에는 선단부(36)가 평기어(18)의 전면안내홈(17)에 삽입되고 중간에는 구동축(21)이 지날 수 있는 안내로(37)가 형성되어 있고 후단부에는 속도조절판(32)의 경사측면(31)이 삽입되는 경사안내구(38)가 형성된 평기어가동축(39)을 착설하여서된 구조이다.As shown in FIGS. 1 to 5, a shaft hole 13 having a plurality of radial grooves 12 is formed at the end of the motor shaft 11 to incorporate the compression spring 14 to accommodate the radial springs 12. The end of the transmission shaft 16 having a radial projection (15) coupled to the insert into the shaft hole 13 of the motor shaft 11, the guide groove 17 in the front center at the other end of the transmission shaft (16) The spur gear 22 mounted on the spur gear 22 is installed by mounting the spur gear 18 having the same, and driving the sprocket 21 to the crank shaft 20 on which the crank 19 is installed. In the occlusal connection, a connecting cap 25 having a shaft hole 24 having several radial grooves 23 formed in the crank shaft 20 is installed, and a tension spring 26 is built in the shaft hole 24. A plurality of radial projections 27 are formed at the lower end of the drive shaft 21 and connected to the connection cap 25, and the spur gear 22 is a multi-stage structure composed of mass gears 22a, 22b and 22c. Furnace drive shaft (21) And the upper end of the drive shaft 21 is connected to one end of the lever 30 arranged on the shaft 29 by the first towing wire 28, and the other end of the lever 30 has the inclined side surface 31. The second towing wire 33 is connected to the adjusting plate 32 and the lower end of the speed adjusting plate 32 is connected to the operation button 35 installed on the seat plate (not shown) by the third towing wire 34. Between the spur gear 18 and the speed regulating plate 32, a tip portion 36 is inserted into the front guide groove 17 of the spur gear 18, and a guide path 37 through which the drive shaft 21 can pass is formed in the middle. The rear end portion has a structure in which a spur gear moving shaft 39 is provided with an inclined guide tool 38 into which the inclined side surface 31 of the speed control plate 32 is inserted.
이와같은 본 고안은 작동버튼(35)을 조작하여 수진이 이루어지지 않도록 할때에는 제3견인와이어(34)를 당기어 주므로서 속도조절판(32)이 하강되어 그 경사축면(31)이 경사안내구(38)에 결합된 평기어가동축(39)를 밀어 평기어(18)의 전면안내홈(17)에 삽입된 평기어가동축(39)의 선단부(36)가 평기어(18)를 후진케하며, 이 평기어(18)는 전동축(16)이 모우터축(11)의 축공(13)내로 스프링(14)을 압축하면서 후진케되나 방사상종요홈(12)과 방사상돌기(15)의 결합으로 모우터축(11)의 회전력이 평기어(18)에 전달되는 상태는 그대로 유지된다. 평기어(18)의 추진으로 이는 스퍼어기어(22)와 분리되므로 구동축(21)이 회전되지 않아 수진이 이루어지지 않는다. 선풍기의 수진이 이루어지도록 하는 경우에는 작동버튼(35)을 조작하여 제3견인와이어(34)를 풀어주면 속도조절판(32)은 상승하고 이에따라 경사측면(31)에 경사안내구(38)가 결합된 평기어가동축(39)이 후진하며 평기어(18)는 스프링(14)의 힘으로 전진하여 스퍼어기어(22)에 결합되어 구동축(21)을 구동시키게 된다.The present invention, such as when operating the operation button 35 to prevent the dust is made by pulling the third towing wire 34, the speed control plate 32 is lowered and its inclined shaft surface 31 is inclined guide A tip 36 of the spur gear movable shaft 39 inserted into the front guide groove 17 of the spur gear 18 by pushing the spur gear movable shaft 39 coupled to the 38 moves backward of the spur gear 18. The spur gear 18 is reversed while the transmission shaft 16 compresses the spring 14 into the shaft hole 13 of the motor shaft 11, but the radial groove 12 and the radial projection 15 The state in which the rotational force of the motor shaft 11 is transmitted to the spur gear 18 by the coupling is maintained. Since the spur gear 22 is separated by the propulsion of the spur gear 18, the driving shaft 21 is not rotated, and thus no dust is generated. If the fan is to be made of water, the operation of the operation button 35 to release the third towing wire 34, the speed control plate 32 is raised and accordingly the inclined guide (38) is coupled to the inclined side 31 The spur gear moving shaft 39 is retracted, and the spur gear 18 is advanced by the force of the spring 14 to be coupled to the spur gear 22 to drive the drive shaft 21.
이때에 작동버튼(35)을 조작하여 속도조절판(32)의 상승정도를 조절하면 제2견인와이어(33), 레바(30) 및 제1견인와이어(28)로 연결된 구동축(21)의 승강정도가 조절되므로 스퍼어기어(22)중에서 대기어(22a), 중기어(22b), 또는 소기어(22c)가 선택적으로 평기어(18)에 결합되어 수진속도 조절이 가능하게 되는 것이다.At this time, by operating the operation button 35 to adjust the lifting degree of the speed control plate 32, the lifting degree of the drive shaft 21 connected to the second towing wire 33, the lever 30 and the first towing wire 28 Since the spur gear 22 is controlled, the standby gear 22a, the heavy gear 22b, or the small gear 22c is selectively coupled to the spur gear 18 to adjust the water speed.
구동축(21)과 이에 교차되는 평기어가동축(39)은 평기어가동축(39)에 넓은 안내로(37)가 형성되어 상호 영향을 주지않는다.The drive shaft 21 and the spur gear moving shaft 39 intersected therewith are formed with a wide guide path 37 formed on the spur gear moving shaft 39 so as not to influence each other.
이와같이 본 고안은 다단의 스퍼어기어를 사용하여 수진속도를 조절할 수 있도록 한 것으로, 수진속도 조절을 위한 별도 모우터를 사용하지 않으므로 제품원가면에서 매우 유리한 이점이 있다.As such, the present invention is designed to control the speed of oscillation using a multi-stage spur gear, and does not use a separate motor for controlling the speed of oscillation, which is very advantageous in terms of product cost.
