본발명을 첨부도면에 의해 상세히 설명하면 다음과 같다.The present invention will be described in detail with the accompanying drawings as follows.
도 1은 본발명의 천정형 조립식 선풍기 사시도, 도 2는 본발명의 다른 실시례의 걸림부 단면도이다.Figure 1 is a perspective view of a ceiling-type prefabricated fan of the present invention, and Figure 2 is a cross-sectional view of a hanging portion of another embodiment of the present invention.
본발명은 천정형 조립식 선풍기는 천정에 부착되는 선풍기본체(100)가 조립,해체가 용이하여 천정에 부착하여 사용하는 것이다.In the present invention, a ceiling-type prefabricated fan is used by attaching it to the ceiling because the fan body 100 is easy to assemble and disassemble.
상기 선풍기본체는 모터가 설치되는 구동부(10), 전달부(20), 날개부(30)로 구성된다. 모터의 회전력은 전달부의 전달축을 거쳐서 날개부의 축류형 날개를 회전시키는 것이다.The fan main body is composed of a driving part 10 on which a motor is installed, a transmission part 20, and a wing part 30. The rotational force of the motor rotates the axial flow blade of the wing section through the transmission shaft of the transmission section.
상기 날개부(30)는 보스(31)주위에 다수개의 날개(32)가 결합된 것으로 상기 보스에 날개가 볼트너트에 의해 조립된다.The wing portion 30 is formed by combining a plurality of wings 32 around a boss 31, and the wings are assembled to the boss using bolts and nuts.
상기 구동부(10)는 모터가 케이싱(11) 내부에 설치된 것으로, 케이싱 상면은 천정에 고정채널에 의해 부착되어 있다.전달부(20)의 전달축 내부는 공간이 형성되어 케이블이 통과된다. The driving unit 10 has a motor installed inside the casing 11, and the upper surface of the casing is attached to the ceiling through a fixed channel. A space is formed inside the transmission shaft of the transmission unit 20 through which the cable passes.
상기 케이싱(11) 하면에는 전달부의 전달축이 결합된다. 케이싱 하면에 구멍을 형성하고 전달축을 상부에서 삽입하여 통과시키되, 전달축의 상단에는 플랜지가 설치되어 플랜지에 의해 구멍에 고정된다. 이때 구멍상단은 나사가 형성되어 전달축의 상부가 나사결합이 된다. 나사방향은 선풍기 회전방향과 반대로 형성한다. 케이스 상면에도 구멍을 형성하고 나사를 천정에 박을 수 있다. 또한 안전장치로 밖에서 펼쳐지는 걸림부가 상단에 형성되어 천정에 고정되는 고정채널에 걸림부를 펼쳐서 걸치게 하여 낙하사고를 예방한다. 또는 걸림부가 장방형으로 형성되어 단면이 'ㄷ'형상의 고정채널에 삽입한후 90도 돌린후 걸림부의 장방형 긴변이 고정채널 홈사이에 걸치게 되어 선풍기가 떨어지지 않고 고정되낟. 본발명은 전달부의 전달축과 구동부 케이스, 그리고 전달축과 하부 날개부 보스는 일체로 사출에 의해 성형하여 제작될 수 있다. 본발명의 재질은 금속 내지 플라스틱재질이 가능하다.The transmission shaft of the transmission unit is coupled to the lower surface of the casing 11. A hole is formed on the bottom of the casing and the transmission shaft is inserted from the top to pass through. A flange is installed at the top of the transmission shaft and is fixed to the hole by the flange. At this time, a screw is formed at the top of the hole and the upper part of the transmission shaft is screwed together. The direction of the screw is opposite to the direction of rotation of the fan. A hole can also be formed on the top of the case and screws can be driven into the ceiling. In addition, as a safety device, a hanging part that extends from the outside is formed at the top, and the hanging part is spread out and hung on a fixed channel fixed to the ceiling to prevent falling accidents. Alternatively, the hanging part is formed in a rectangular shape and is inserted into a fixing channel with a 'ㄷ' shaped cross section. After turning it 90 degrees, the rectangular long side of the hanging part hangs between the fixing channel grooves so that the fan is fixed without falling. In the present invention, the transmission shaft of the transmission unit, the drive unit case, and the transmission shaft and lower wing boss can be manufactured by molding as one body by injection molding. The material of the present invention can be metal or plastic.
특히 본발명은 케이싱 측면에 개폐구가 형성되고 개폐문이 설치되어 있다. 그러므로 개폐구는 상하로 슬라이딩동작되어 개폐구를 개폐한다.개폐구를 통해 모터 등 전기부품의 선을 정비할 수 있다.In particular, in the present invention, an opening and closing opening is formed on the side of the casing and an opening and closing door is installed. Therefore, the gate slides up and down to open and close the gate. The wires of electrical components such as motors can be maintained through the gate.
그리고 상기 천정형 조립식 선풍기는 리모콘에 의해 온오프 및 속도조절이 되는 것이다. 그리고 진동센서와 제어기가 선풍기본체에 설치되어, 일정진동수 이상의 진동이 감지되면 제어기의 제어부는 선풍기의 전원을 오프시켜 안전을 도모한다. 그리고 모터의 발열도 점검하여 일정온도 이상의 발열이 온도센서에 의해 감지되면 모터동작을 정지시킨다. 한편 무게센서, 장력센서가 선풍기본체에 설치되어 선풍기가 사고로 낙하되면 센서가 이를 감지하여 제어부에 전송하고 제어부는 설정치 이하의 무게가 산정되면 낙하로 간주하여 경보수단인 비상알람을 울리게 된다. 지진 등이 발생되면 선풍기의 진동과 공진이 일어나서 선풍기가 쉽게 파손되므로 지진감지센서의 신호를 전송받은 제어부는 지진파로 판단되면 선풍기의 구동을 중지시킨다. 한편, 상기 선풍기 걸림부는 단면이 도2와 같이 일자형 몸체 양단에 전후방수평걸림편이 반대방향으로 수평으로 형성된 형상이 되어, 채널에 삽입후 채널 내벽 하부에서 돌출되는 전후돌기에 의해 회전이 각각 제한되게 된다. 전후방수평 걸림편 방향은 각각 선풍기 회전방향과 반대방향으로 연장되어 회전을 제한하게 된다. 전후돌기는 하부에 스프링이 형성되어 위에서 수평걸림편이 누르면 하부구멍에 삽입되었다가 다시 올라와서는 수평걸림편이 회전되지 않게 한다.And the ceiling-type prefabricated fan is turned on and off and its speed is controlled by a remote control. Additionally, a vibration sensor and a controller are installed in the fan body, and when vibration above a certain frequency is detected, the control unit of the controller turns off the power of the fan to ensure safety. Additionally, the motor's heat is checked, and if heat above a certain temperature is detected by the temperature sensor, the motor operation is stopped. Meanwhile, a weight sensor and a tension sensor are installed in the fan body, so if the fan accidentally falls, the sensor detects this and transmits it to the control unit. If the weight is calculated to be less than the set value, the control unit considers it as a fall and sounds an emergency alarm, which is an alarm. When an earthquake occurs, vibration and resonance of the fan occur and the fan is easily damaged. Therefore, the control unit that receives the signal from the earthquake detection sensor stops the operation of the fan when it is judged to be a seismic wave. Meanwhile, the fan locking portion has a cross-section as shown in Figure 2 with front and rear horizontal locking pieces formed horizontally in opposite directions at both ends of the straight body, so that rotation is restricted by front and rear protrusions protruding from the lower part of the inner wall of the channel after insertion into the channel. . The directions of the front and rear horizontal locking pieces extend in the opposite direction to the rotation direction of the fan, thereby limiting rotation. The front and rear protrusions have springs formed at the bottom, so that when the horizontal locking piece is pressed from above, they are inserted into the lower hole and come back up to prevent the horizontal locking piece from rotating.
따라서 본발명은 천정에 부착되는 선풍기본체(100)가 조립,해체가 용이하며 설치가 간단하며 안전하게 사용할 수 있는 현저한 효과가 있다.Therefore, the present invention has the remarkable effect that the fan body 100 attached to the ceiling is easy to assemble and disassemble, is simple to install, and can be used safely.
