본 고안은 360°또는 그 이하의 각도 범위에서 선풍기헤드 부분이 회전하여 풍향이 변환할 수 있도록한 선풍기, 특히 스탠드형 선풍기의 풍향 변환 장치에 관한 것이다.The present invention relates to a wind direction conversion device of a fan, in particular a stand type fan, in which the fan head portion rotates in an angle range of 360 ° or less.

종래 선풍기헤드 또는 넥크 부분에 정회전력에 어떠한 구속력이 가하여지면 역회전 하는 별도의 동기모우터를 이용하여 일정한 각도 범위내에서 선풍기헤드가 반복회전토록하며 이 각도 범위를 선택하여 풍향변환이 이루어지도록 한 것이 알려져 있으며, 동기모우터에 가하여지는 구속력을 해제하므로서 선풍기헤드가 일방향으로 연속 360°회전토록 하는 것이 알려져 있다. 그러나 이들 종래 기술에 있어서는 동기모우터에 구속력을 가하기 위한 조작 구조가 복잡할 뿐아니라 부품수가 증가하여 원가 상승의 요인이 된다. 또한 선풍기헤드가 연속 360°회전토록 하는 구성과 일정한 각도 범위 내에서 반복 회전토록 하는 구성을 결합하는 경우 그동기모우터로의 급전 장치와 함께 동기모우터에 구속력을 가하기 위한 조작 구조가 선풍기헤드 또는 넥크하우징의 좁은 공간내에 설치되어야하므로 그 조립에 있어서 많은 시간과 경비가 소요되는 결점이 있었다.When any constraining force is applied to the turning fan head or neck in the conventional fan head, the fan head is repeatedly rotated within a certain angle range by using a separate synchronous motor that rotates in reverse, so that the direction of the wind is changed by selecting this angle range. It is known that the fan head rotates 360 ° continuously in one direction while releasing the restraining force applied to the synchronous motor. However, in these prior arts, not only the operation structure for applying the restraining force to the synchronous motor is complicated, but also the number of parts increases, which causes a cost increase. In addition, when the fan head is configured to rotate continuously 360 ° and the configuration to be repeatedly rotated within a certain angle range, the operation structure for applying a binding force to the synchronous motor together with the feeding device to the synchronous motor has a fan head or Since it had to be installed in the narrow space of the neck housing, there was a drawback in that the assembly took a lot of time and expense.

본 고안에 있어서는 종래의 이와 같은 점을 감안하고, 이를 규모가 큰 스탠드형 선풍기에 적용토록한 것으로, 선풍기헤드의 360°연속 회전과 일정한 각도 범위, 예를 들어 120°의 범위 내에서의 반복 회전이 간단한 구조로 이루어질 수 있도록 하는 동시에 부품수를 현저히 줄이므로서 제조 경비를 줄일 수 있도록 한 것인바, 이를 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention, in view of such a conventional point, it is applied to a large-sized stand-type fan, and the 360 ° continuous rotation of the fan head and the repeated rotation within a constant angle range, for example, the range of 120 ° This simple structure can be made while reducing the number of parts while significantly reducing the number of parts, which will be described in more detail based on the accompanying drawings as follows.

원통형 지주봉(1)상에 2단원 통체로된 하부지지대(2)를 착설하고 이 하부지지대(2)의 중앙에는 축관(3)을 일체로 입설하여 이에 축공(4)과 이 축공(4)의 직경 방향으로 수직 연장된 핀홈(5)을 요설하고, 또한 하부지지대(2)의 내부 상부면에는 수 개의 동심원상 급전대(6)(6')가 배설되어 전원용 코드(7)가 연결된 급전판(8)을 착설하며, 하부지지대(2)상에는 이에 고정된 지지링(9)으로 급전부러쉬(15)를 갖는 하측 지지원반(10)이 회전가능하게 지지되고 선풍기헤드(도시하지 않았음)의 일부를 구성하는 원통형상의 상부지지대(11)를 상치하여 상부지지원반(10)을 통하여 하부지지대(2)의 축공(4)에 삽입하고 회전축(13)의 하단에 삽착된 핀(14)이 핀홈(5)에 삽입되어 공회전이 방지 되도록 한 것에 있어서, 하부지지대(2)의 상측 변부 주연에 동일한 간격, 예를 들어 120°의 간격을 둔 돌기(16)를 돌설하고, 상부지지대(11)의 하측변부 주연에는 "L"자형의 대향된 안내대(17)(17')를 입설하여 그 내면에 상, 하 한쌍의 삼각 요구(18)(18')를 요설하며, 이 안내대(17)(17') 사이에는 거의 판상으로 측부에 삼각돌기(19)(19')가 돌설되고 내부 양측으로 장요홈(20)(20')이 요설되어 있으며 표면에 미끄럼 방지용 돌조(21)가 돌설된 레바(22)를 삽설하여서된 구조이다.A lower support (2) consisting of a two-stage cylindrical body is installed on the cylindrical support rod (1), and a shaft pipe (3) is integrally installed in the center of the lower support (2), thereby the shaft hole (4) and the shaft hole (4). A pin groove 5 extending vertically in the radial direction, and several concentric feeders 6 and 6 'are disposed on the inner upper surface of the lower support 2 so that the power supply cord 7 is connected. The board 8 is installed, and the lower support disk 10 having the feeder part rush 15 is rotatably supported by a support ring 9 fixed thereto on the lower support 2, and a fan head (not shown). The pin 14 inserted into the shaft hole 4 of the lower support 2 through the upper support plate 10 and the upper support 11 of the cylindrical portion constituting a portion of the pin 14 is inserted Inserted into the pin groove 5 to prevent idling, the same distance to the peripheral edge of the upper side of the lower support 2, for example 120 Protruding the spaced projections 16, the opposite side of the lower side of the upper support 11 is inserted into the opposite guide 17 (17 ') of the "L" shape and a pair of upper and lower triangles on the inner surface Requests 18 and 18 'are provided, and between the guides 17 and 17', triangular projections 19 and 19 'are protruded on the sides in a substantially plate shape, and the grooves 20 on both sides inside ( 20 ') is provided by inserting the lever 22 in which the anti-slip protrusion 21 is protruded on the surface.

이와 같은 본 고안은 선풍기헤드의 팬을 회전시키고 동기모우터(12)를 구동시킬 때에 그 회전축(13)이 하부지지대(2)에 고정되어 있으므로 이 화부지지대(2)에 대하여 선풍기헤드의 일부를 이루는 상부지지대(11)가 회전하는 것으로서, 레바(22)를 그 표면의 돌조(21)를 이용하여 상측으로 밀어올려 장요홈(20)(20')에 의하여 탄성이 부여된 레바(22)측부의 삼각돌기(19)(19')가 안내대(17)(17')의 상부측 삼각요구(18)(18')에 삽입되어 고정되는 경우 상부지지대(11)는 일측 방향으로 360°연속회전하게 될 것이다. 또한 레바(22)를 내려 삼각돌기(19)(19')가 안내대(17)(17')의 삼각요구(18)(18')에 삽입 고정되는 경우 레바(22)의 하측부가 하부지지대(2)의 상측변부 주연에 돌설한 돌기(16) 사이의 구간에서 이들 돌기(16)에 닿아 동기모우터(12)에 구속력을 가하므로서 상부지지대(11)는 양측돌기(16)가 이루는 각도 범위에서 반복 회전하게 되는 것이다.The present invention as described above rotates the fan of the fan head and drives the synchronous motor 12, so that the rotating shaft 13 is fixed to the lower support (2) part of the fan head with respect to the fire support (2). As the upper support 11 is rotated, the lever 22 is pushed upward by using the protrusion 21 on the surface thereof so that the elastic part 22 is elastically provided by the jangyo grooves 20 and 20 '. When the triangular projections 19, 19 'are inserted into and fixed to the upper triangular demands 18, 18' of the guides 17, 17 ', the upper support 11 is continuous 360 ° in one direction. Will rotate. In addition, when lowering the lever 22 and the triangular projections 19 and 19 'are inserted into and fixed to the triangular demands 18 and 18' of the guides 17 and 17 ', the lower part of the lever 22 is supported by the lower supporter. In the section between the protrusions 16 protruding from the upper edge of (2), the upper support 11 is formed by both side protrusions 16 while touching the protrusions 16 and applying a restraining force to the synchronous motor 12. It will rotate repeatedly in the angular range.

이와 같이 본 고안은 선풍기헤드의 360°연속회전과 설정된 각도 범위에서의 반복 회전이 간단한 구조의 선택적인 조작으로 이루어질 수 있는 것이다.As such, the present invention may be made by selective operation of a simple structure of 360 ° continuous rotation of the fan head and repeated rotation in a set angle range.
