본 고안은 모터팬 취부구조에 관한 것으로, 더욱 상세하게는 모터축에 팬(FAN)을 고정하는 경우 별도의 보스 및 체결부재가 불필요하게 되어 작업성을 향상시키며 팬에 대해 보스를 고정후 사출성형시 불량 발생됨을 방지할 수 있도록 한 모터팬 취부구조에 관한 것이다.The present invention relates to a motor fan mounting structure. More specifically, when fixing a fan to a motor shaft, an additional boss and a fastening member are unnecessary, thereby improving workability and injection molding after fixing a boss to a fan. The present invention relates to a motor fan mounting structure for preventing occurrence of defects at the time.
제1도에 개략적으로 도시된 바와같이, 에어콘등의 실내기, 실외기에 장착되어 회전시 흡입력에 의해 외부공기를 흡입하는 종래기술에 의한 모터팬(MOTOR-FAN)의 취부구조는, 팬(1)의 사출성형시 재질이 상이한 별도의 보스(2)를 소정위치에 가고정한 상태에서 팬(1)을 사출제작하며, 모터팬의 조립시 별도의 체결부재(3)를 이용하여 보스(2)와 모터축(4)을 고정시키는 것이다.As schematically shown in FIG. 1, a mounting structure of a motor-fan according to the prior art, which is mounted to an indoor unit or an outdoor unit such as an air conditioner and sucks external air by suction power during rotation, is a fan (1). In the injection molding of the fan (1) is injection-fabricated in a state in which a separate boss (2) different from the material is temporarily fixed to a predetermined position, and when assembling the motor fan using a separate fastening member (3) and the boss (2) The motor shaft 4 is fixed.
따라서, 모터팬 고정시 별도의 보스(2) 및 체결부재(3) 사용으로 인한 원가상승은 물론, 모터팬 조립시 팬(1)의 이웃한 날개(깃)사이로 드라이버등의 공구를 이용하게 되므로 작업이 불편하며, 모터팬 구동시 팬(1)이 모터축(4)으로부터 이탈됨을 방지하기 위해 보스(2)와 모터축(4)을 고정시키는 체결부재(3)의 결합부위에 본드제를 도포시켜야 되므로 작업성이 저하된다.Therefore, as well as the cost increase due to the use of a separate boss (2) and fastening member (3) when fixing the motor fan, as well as tools such as drivers are used between the adjacent blades (flags) of the fan (1) when assembling the motor fan. The work is inconvenient, and in order to prevent the fan 1 from being disengaged from the motor shaft 4 when the motor fan is driven, a bonding agent is attached to the coupling part of the fastening member 3 which fixes the boss 2 and the motor shaft 4. Since it has to be applied, workability is reduced.
그리고, 팬(1)의 사출성형시 보스(2)의 중심위치를 정확하게 맞추지 못하는 경우 팬(1) 회전시 이상소음으로 인한 불량 발생율이 높은 것이었다.In addition, when the center position of the boss 2 is not accurately matched during the injection molding of the fan 1, the failure rate due to abnormal noise during the rotation of the fan 1 was high.
따라서, 본 고안의 목적은, 모터축에 팬을 고정시키는 경우 별도의 체결부재 및 보스사용이 불필요하게 되므로 원가비용을 줄이며, 모터팬 구동시 모터축으로부터 팬 이탈방지 부재가 불필요하며 이에 따른 작업성을 향상시킬 수 있도록 한 모터팬 취부구조를 제공하는 것이다.Accordingly, an object of the present invention is to reduce the cost cost because it is unnecessary to use a separate fastening member and the boss when fixing the fan to the motor shaft, the need to prevent the fan separation from the motor shaft when driving the motor fan and workability accordingly It is to provide a motor fan mounting structure to improve the performance.
전술한 본 고안의 목적은, 모터축에 팬을 고정시키는 모터팬 취부구조에 있어서, 상기 팬의 보스 내주연에 형성된 돌기부와, 상기 보스에 삽입시 상기 돌기부와 결합되어 상기 보스에 대해 모터축을 고정시키는 가이드홈을 구비하여 구성됨을 특징으로 하는 모터팬 취부구조를 제공함에 의해 달성된다.An object of the present invention described above, in the motor fan mounting structure for fixing the fan to the motor shaft, the projection formed on the inner periphery of the boss of the fan, and coupled to the projection when inserted into the boss to secure the motor shaft to the boss It is achieved by providing a motor fan mounting structure characterized in that it comprises a guide groove to make.
본 고안의 바람직한 특징은, 상기 가이드홈 일측으로 형성되어 상기 팬 구동시 상기 모터축으로부터 팬의 이탈됨을 방지하는 록킹홈을 더 구비한다.According to a preferred feature of the present invention, the guide groove further includes a locking groove which is formed at one side of the guide groove to prevent the fan from being separated from the motor shaft when the fan is driven.
이하, 본 고안의 바람직한 실시예를 첨부도면에 따라 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도에 도시된 바와같이, 에어콘등의 실내기, 실외기에 장착되어 외부공기를 흡입하는 팬(10)의 보스(11) 내주연에 구형상의 돌기부(12)가 형성되며, 보스(11)에 삽입되는 모터축(13) 외주연에 축방향으로 반구형상의 가이드홈(14)을 형성하되, 가이드홈(14)에 전술한 팬(10) 구동시 모터축(13)으로부터 팬(10)의 이탈됨을 방지하는 록킹홈(15)이 연장형성된다.As shown in FIG. 2, a spherical protrusion 12 is formed at the inner circumference of the boss 11 of the fan 10, which is mounted to an indoor unit or an outdoor unit such as an air conditioner and sucks external air, and is formed on the boss 11. A hemispherical guide groove 14 is formed on the outer circumference of the motor shaft 13 to be inserted in the axial direction, and the fan 10 is separated from the motor shaft 13 when the fan 10 is driven in the guide groove 14. Locking groove 15 is formed to prevent the extension.
위와같은 본 고안의 작동을 설명하면, 모터팬 조립시 팬(10)의 보스(11)에 형성된 돌기부(12)에 대해 모터축(13)의 가이드홈(14)을 일치시켜 삽입시킨 다음, 모터축(13)을 시계방향으로 소정각도로 회전시켜주면 가이드홈(14)에 연장 형성된 록킹홈(15)에 팬(10)의 돌기부(12)가 안착되며, 이로인해 팬(10) 구동시 즉, 팬(10)이 시계방향으로 회전하게 되므로 돌기부(12)가 록킹홈(15)으로부터 이탈됨이 방지되어 모터축(13)으로부터 팬(10)의 이탈됨은 방지되는 것이다.Referring to the operation of the present invention as described above, the guide groove 14 of the motor shaft 13 to match the projection 12 formed in the boss 11 of the fan 10 when the motor fan assembly, and then insert the motor When the shaft 13 is rotated by a predetermined angle in the clockwise direction, the protrusion 12 of the fan 10 is seated in the locking groove 15 formed in the guide groove 14, thereby driving the fan 10. Since the fan 10 rotates in the clockwise direction, the protrusion 12 is prevented from being separated from the locking groove 15, thereby preventing the fan 10 from being separated from the motor shaft 13.
한편, 팬(10) 또는 모터(16)를 수리점검하는 경우에는 모터축(13)에 대해 팬(10)을 반시계방향으로 소정각도 범위내에서 회전시켜주면, 팬(10)의 돌기부(12)가 록킹홈(15)으로부터 이탈되어 가이드홈(14)에 위치하게 되며, 이때 팬(10)을 모터축(13)으로부터 축방향으로 분리시키면 모터(16)와 팬(10)의 분리는 완료되는 것이다.On the other hand, in the case of repairing the fan 10 or the motor 16, if the fan 10 is rotated in the counterclockwise direction within a predetermined angle range with respect to the motor shaft 13, the projections 12 of the fan 10 ) Is separated from the locking groove 15 and positioned in the guide groove 14. At this time, when the fan 10 is separated from the motor shaft 13 in the axial direction, the separation of the motor 16 and the fan 10 is completed. It will be.
이상에서와 같이 본 고안에 의한 모터팬 취부구조는, 에어콘등의 실내기, 실외기에 장착되는 팬을 모터축에 고정시키는 경우 별도의 보스 및 체결부재가 불필요하여 원가비용을 줄이며, 팬의 구동시 모터축으로 이탈됨을 방지하는 부재가 불필요하게 되므로 조립성을 향상시키며, 모터축에 대해 팬의 중심위치를 맞추는 과정이 불필요해 불량발생율을 줄일 수 있는 것이다.As described above, the motor fan mounting structure according to the present invention, when fixing the fan mounted to the indoor unit, such as air conditioners, outdoor unit to the motor shaft, a separate boss and fastening member is unnecessary, reducing the cost cost, the motor during the drive of the fan Since the member preventing the deviation from the shaft is unnecessary, the assembly is improved, and the process of aligning the center of the fan with respect to the motor shaft is unnecessary, thereby reducing the failure rate.
