상기한 과제를 실현하기 위한 본 발명에 따른 공기조화기의 송풍팬은 구동모터의 회전축이 끼움 결합되는 팬 허브와, 상기 팬 허브의 둘레방향으로 장착되어 송풍작용을 하는 회전날개와, 상기 회전날개와 팬 허브 사이에 장착되어 구동모터에서 발생되는 진동 및 소음을 흡수하는 흡진부재로 이루어진다.Blowing fan of the air conditioner according to the present invention for realizing the above object is a fan hub to which the rotary shaft of the drive motor is fitted, the rotary blade mounted in the circumferential direction of the fan hub and the blowing blades, the rotary wing And a suction member mounted between the fan hub and absorbing vibration and noise generated from the driving motor.
이하, 첨부된 도면을 참조하여 본 발명의 일실시예를 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
도 2는 본 발명에 따른 공기조화기용 송풍팬의 단면도이고, 도 3은 도 2 A부의 확대도이다.2 is a cross-sectional view of a blower fan for an air conditioner according to the present invention, and FIG. 3 is an enlarged view of a portion A of FIG. 2.
이러한 송풍팬은 중앙측에 위치되고 구동모터(4)의 회전축(6)이 끼움 결합되는 삽입홀(8)이 형성되는 팬 허브(10)와, 이 팬 허브(10)의 둘레방향으로 일체로 형성되어 송풍작용을 하는 회전날개(12)와, 상기 회전날개(12)와 팬 허브(10) 사이를 연결하는 연결리브(16)에 장착되어 구동모터(4)의 진동 및 소음이 회전날개(12) 측으로 전달되는 것을 방지하는 흡진부재(18) 등으로 구성된다.The blower fan is located at the center and integrally formed in the circumferential direction of the fan hub 10 with the fan hub 10 having an insertion hole 8 formed therein to which the rotary shaft 6 of the driving motor 4 is fitted. It is formed and mounted on the rotary blade 12 for blowing and the connecting rib 16 for connecting between the rotary blade 12 and the fan hub 10, the vibration and noise of the drive motor 4 is the rotary blade ( 12) is composed of a suction member 18 and the like to prevent the transfer to the side.
상기 팬 허브(10)는 중앙측에 구동모터의 회전축(6)이 삽입되는 삽입홀(8)이 형성되고, 그 외주면 둘레방향으로 진동 및 소음을 흡수하는 흡진부재(18)가 장착된다.The fan hub 10 has an insertion hole 8 into which the rotation shaft 6 of the driving motor is inserted in the center side thereof, and is equipped with a suction member 18 that absorbs vibration and noise in the circumferential direction of the outer peripheral surface thereof.
상기 회전날개(12)는 팬 허브(10)와 연결리브(16)에 의해 연결되고 팬허브(10)의 원주방향으로 일정간격으로 다수개로 형성되어 회전시 송풍작용을 수행한다.The rotary blades 12 are connected by the fan hub 10 and the connecting rib 16 and formed in plural at regular intervals in the circumferential direction of the fan hub 10 to perform a blowing operation during rotation.
상기 흡진부재(18)는 팬 허브(10)의 외주면에 고정되는 고정부(20)와, 이 고정부(20)의 일측에 일정 폭만큼 돌출되어 상기 연결리브(16)에 고정되는 플랜지부(22)로 이루어진다.The suction member 18 may include a fixing part 20 fixed to the outer circumferential surface of the fan hub 10 and a flange part protruding to one side of the fixing part 20 by a predetermined width to be fixed to the connecting rib 16. 22).
즉, 상기 흡진부재(18)는 팬 허브(10)와 회전날개(12) 사이에 장착되어 팬 허브(10)에 끼움 결합된 구동모터의 회전축(6)을 통해 전달되는 진동 및 소음을 흡수하여 회전날개(12)측으로 전달되는 것을 저감시킬 수 있는 고무 재질의 흡진제로 이루어짐이 바람직하다.That is, the suction member 18 is mounted between the fan hub 10 and the rotary blade 12 to absorb the vibration and noise transmitted through the rotary shaft 6 of the drive motor fitted to the fan hub 10 by It is preferably made of a rubber reducer that can reduce the transmission to the rotary blade 12 side.
이와 같은 본 발명에 따른 송풍팬은 구동모터(4)가 구동되면 회전축(6)이 회전되고, 이에 따라 송풍팬이 회전되면서 송풍작용을 수행한다. 이때, 흡진부재(18)가 구동모터(4)에서 발생되는 진동 및 소음이 송풍팬으로 전달되는 것을 저감시켜 송풍팬 회전시 진동 및 소음 발생을 저감시킨다.Such a blowing fan according to the present invention, when the driving motor 4 is driven, the rotating shaft 6 is rotated, thereby performing a blowing operation while the blowing fan is rotated. At this time, the vibration absorbing member 18 reduces the vibration and noise generated from the driving motor 4 to the blowing fan to reduce the vibration and noise generated when the blowing fan rotates.
따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 공기정화기의 송풍팬은 구동모터의 회전축이 끼워지는 팬 허브와 회전날개가 연결되는 연결리브 사이에 흡진 작용을 하는 흡진부재를 설치함으로써, 구동모터에서 발생되는 진동 및 소음이 송풍팬으로 전달되는 것을 저감시킬 수 있고, 구동모터의 회전축과 팬 허브 사이의 장착구조가 불일치될 경우에도 송풍팬의 울렁거림을 방지하여 제품의 품질을 향상시킬 수 있는 이점이 있다.Therefore, the blower fan of the air purifier according to the present invention configured and operated as described above, by installing a suction member that acts as a suction member between the fan hub to which the rotating shaft of the drive motor is fitted and the connecting rib connected to the rotary blades, It is possible to reduce the vibration and noise generated from the blower fan and to improve the quality of the product by preventing the blowing fan from rumble even when the mounting structure between the rotating shaft of the drive motor and the fan hub is inconsistent. There is an advantage.
