It relates to a blower fan mounting structure of the air conditioner that can be robust.

일반적으로 공기 조화기는 난방기, 냉방기, 공기 정화기 등으로 실내를 냉난방시키거나 공기를 정화할 목적으로 설치되어 인간에게 보다 쾌적한 실내 환경을 조성하는 역할을 한다.In general, the air conditioner is installed for the purpose of heating or cooling the room or purifying the air with a heater, an air conditioner, an air purifier, etc., and serves to create a more comfortable indoor environment for humans.

이러한 공기 조화기는 실내의 공기를 흡입하는 송풍팬과 이 송풍팬을 구동시키는 송풍모터와, 송풍팬에 의해 흡입된 공기가 통과하면서 가열 및 냉각되는 열교환기 등으로 이루어진다.The air conditioner includes a blower fan for sucking air in the room, a blower motor for driving the blower fan, and a heat exchanger for heating and cooling while the air sucked by the blower fan passes.

도 1은 종래 기술에 따른 송풍팬과 송풍모터 사이의 장착구조를 나타낸 정면도이고, 도 2는 도 1 A-A 선의 단면도이다.1 is a front view illustrating a mounting structure between a blower fan and a blower motor according to the prior art, and FIG. 2 is a cross-sectional view taken along the line A-A of FIG. 1.

송풍팬은 중앙측에 위치한 팬 허브(102)와, 팬 허브(102)의 둘레방향으로 형성되어 송풍작용을 하는 회전날개(104)와, 팬 허브(102)의 중앙측에 형성되어 송풍모터(미도시)와 연결되는 모터 장착홈(106)으로 이루어지고, 모터 장착홈(106)에는 모터의 회전축(108)이 끼워지고, 회전축(108)이 이탈되는 것을 방지하기 위해 모터 장착홈(106)과 회전축(108) 사이에 클램프(110)가 장착된다The fan is a fan hub 102 located on the center side, the rotary blade 104 is formed in the circumferential direction of the fan hub 102 and blows, and is formed on the center side of the fan hub 102 and the blower motor ( The motor mounting groove 106 is connected to the motor mounting groove 106, and the motor mounting groove 106 is fitted into the motor mounting groove 106 to prevent the rotation shaft 108 from being separated. The clamp 110 is mounted between the shaft 108 and the rotary shaft 108.

상기 팬 허브(102)의 모터 장착홈(106)은 일정 간격을 갖고 3등분으로 분리되어 있고, 그 사이에 모터의 회전축(108)을 끼운 뒤 팬 허브(102)의 외측 둘레로 클램프(110)를 장착한 후 클램프(110)를 조이면 3등분된 모터 장착홈(106)의 간격이 좁아지면서 송풍모터의 회전축(108)이 팬 허브(102)에 고정된다.The motor mounting groove 106 of the fan hub 102 is divided into three equal parts at regular intervals, and between the clamp shaft 110 around the outer side of the fan hub 102 after sandwiching the rotating shaft 108 of the motor therebetween. After mounting the clamp 110 and tightening the clamp 110, the interval of the motor mounting groove 106 divided into three is narrowed and the rotating shaft 108 of the blower motor is fixed to the fan hub 102.

그러나, 상기한 바와 같은 종래 기술에 따른 송풍팬 장착구조는 송풍모터에서 발생되는 진동이 송풍팬으로 전달되어 송풍팬의 회전을 방해함과 아울러 소음이 발생되고, 또한 송풍팬과 송풍모터 사이는 클램프에 의해 고정되기 때문에 송풍팬의 고정을 위해 별도의 부품을 필요로 하여 조립 부품수가 증가되는 문제점이 있다.However, in the blower fan mounting structure according to the related art as described above, the vibration generated from the blower motor is transmitted to the blower fan, which hinders the rotation of the blower fan and generates noise, and also the clamp between the blower fan and the blower motor is clamped. Since it is fixed by the need for a separate part for fixing the blowing fan there is a problem that the number of assembly parts increases.

상기한 과제를 실현하기 위한 본 발명에 따른 공기 조화기용 송풍팬 장착구조는 송풍작용을 하는 회전날개가 둘레방향으로 일체로 팬 허브가 형성되고, 상기 팬 허브의 중앙측에 형성되는 모터 장착홀에 송풍모터의 회전축이 끼워지고, 상기 팬 허브의 모터 장착홈의 내측에 일체로 형성되어 송풍모터의 회전축을 탄성적으로 지지하고, 송풍모터로부터의 진동이 송풍팬으로 전달되는 것을 차단하는 완충부가 형성되어짐을 특징으로 한다.Blowing fan mounting structure for an air conditioner according to the present invention for realizing the above problem is formed in the motor mounting hole formed in the central side of the fan hub, the fan blade is formed integrally in the circumferential direction of the rotary blades The rotary shaft of the blower motor is fitted, integrally formed inside the motor mounting groove of the fan hub to elastically support the rotary shaft of the blower motor, and a shock absorbing portion for blocking vibration from the blower motor from being transmitted to the blower fan. It is characterized by.

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 3은 본 발명에 따른 송풍팬과 송풍모터 사이의 장착구조를 나타낸 사시도이고, 도 4는 도 3 B-B 선의 단면도이다.3 is a perspective view illustrating a mounting structure between a blower fan and a blower motor according to the present invention, and FIG. 4 is a cross-sectional view taken along line BB of FIG. 3.

송풍팬 장착구조는 송풍작용을 하는 회전날개(2)가 둘레방향으로 일체로 연결되는 팬 허브(4)와, 이 팬 허브(4)의 중앙측에 형성되는 모터 장착홀(10)에 끼워지는 송풍모터의 회전축(8)과, 팬 허브(4)의 모터 장착홈(10) 내주면에 일체로 형성되어 송풍모터의 회전축(8)을 고정시킴과 아울러 송풍모터로부터의 진동이 송풍팬으로 전달되는 것을 차단하는 완충부(6)로 이루어진다.The blowing fan mounting structure includes a fan hub (4) to which the rotary blade (2) which blows is integrally connected in the circumferential direction, and a motor mounting hole (10) formed at the center side of the fan hub (4). It is formed integrally with the rotation shaft 8 of the blower motor and the inner circumferential surface of the motor mounting groove 10 of the fan hub 4 to fix the rotation shaft 8 of the blower motor, and the vibration from the blower motor is transmitted to the blower fan. It consists of a buffer part 6 to block the thing.

팬 허브(4)는 원통형태로 중앙측에 송풍모터가 장착되는 모터 장착홈(10)이 형성되고, 이 모터 장착홈(10)은 길이방향으로 다수개로 분할되어 있으며, 이 분할된 각 부분 사이는 일정 간격을 유지하고 있다.The fan hub 4 has a cylindrical shape in which a motor mounting groove 10 in which a blower motor is mounted is formed at the center thereof, and the motor mounting groove 10 is divided into a plurality of longitudinally, and between the divided portions. Maintains a certain interval.

완충부(6)는 팬 허브의 모터 장착홈(10) 내주면에 일정간격을 두고 형성되는 원통형태의 탄성체로서, 팬 허브(4)와 동일하게 분할되고, 그 내주면에 송풍모터의 회전축(8)이 억지 끼움된다. 즉, 완충부(6)는 팬 허브(4)의 내주면에 둘레방향으로 일정 간격을 두고 위치되고, 그 한쪽 끝부분은 팬 허브(4)에 일체로 연결되는 탄성체로 이루어진다.The shock absorbing portion 6 is a cylindrical elastic body formed at regular intervals on the inner circumferential surface of the motor mounting groove 10 of the fan hub and is divided in the same manner as the fan hub 4, and the rotary shaft 8 of the blower motor is formed on the inner circumferential surface thereof. This is forced. That is, the shock absorbing portion 6 is positioned at regular intervals in the circumferential direction on the inner circumferential surface of the fan hub 4, and one end thereof is formed of an elastic body integrally connected to the fan hub 4.

이러한 완충부(6)는 그 자체에 일정 탄성력을 보유하고 있기 때문에 송풍모터의 회전축(8)이 억지 끼움된 상태에서 같이 회전되고, 모터 장착홈(10)과의 사이에 일정 간격을 두고 형성되므로 회전축(8)에서 발생되는 진동 및 소음에 대해 완충되는 작용을 한다.Since the shock absorbing part 6 retains a certain elastic force in itself, the shock absorbing part 6 is rotated together in a state in which the rotary shaft 8 of the blower motor is fitted, and is formed at a predetermined interval between the motor mounting grooves 10. It functions to cushion the vibration and noise generated in the rotary shaft (8).

이와 같이 이루어진 송풍팬 장착 방법은 다음에서 설명한다.The blowing fan mounting method made in this way will be described below.

팬 허브(4)에 형성된 모터 장착홈(10)의 내측으로 형성된 완충부(6)에 송풍모터의 회전축(8)을 억지 끼움시키면 송풍모터와 송풍팬 사이의 조립이 완료된다. 이러한 상태에서 송풍모터를 구동시키면 회전축(8)의 회전이 팬 허브(4)로 전달되어 회전날개(2)가 회전되면서 송풍작용을 한다. 이때, 회전축(8)은 완충부(6)에 탄성적으로 끼워져 있어 회전축(8)에서 발생되는 진동 및 소음의 완충작용을 하고 조립이 간편하다.When the rotary shaft 8 of the blower motor is forcibly inserted into the buffer part 6 formed inside the motor mounting groove 10 formed in the fan hub 4, the assembly between the blower motor and the blower fan is completed. When the blower motor is driven in this state, the rotation of the rotary shaft 8 is transmitted to the fan hub 4 so that the rotary blade 2 rotates and blows. At this time, the rotating shaft 8 is elastically fitted to the shock absorbing portion 6, and the vibration and noise generated from the rotating shaft 8, the shock absorbing action and easy assembly.

따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 공기 조화기의 송풍팬 장착구조는 팬 허브의 모터 장착홈 내측에 둘레방향으로 완충부를 형성하여 송풍모터의 회전축을 탄성적으로 억지 끼움함으로써, 송풍모터의 진동 및 소음이 완충부에서 완충작용으로 흡수하여 송풍팬으로 전달되는 것을 방지할 수 있고, 또한 완충부에 회전축을 끼우는 작업에 의해 조립이 완료되므로 조립성이 향상되고, 조립부품을 줄일 수 있는 이점이 있다.Therefore, the blower fan mounting structure of the air conditioner according to the present invention constructed and acted as described above forms a shock absorbing portion in the circumferential direction inside the motor mounting groove of the fan hub to elastically press the rotary shaft of the blower motor, thereby blowing The vibration and noise of the motor can be prevented from being absorbed by the shock absorbing function at the shock absorbing part and transmitted to the blower fan. Also, assembling is completed by inserting the rotating shaft into the shock absorbing part, the assembly performance is improved and the assembly parts can be reduced. There is an advantage to that.
