It is about a crossflow fan.
일반적으로 크로스플로우팬은 냉장실의 상부 즉, 냉장고의 사절부 하부면을 따라 형성된 순환덕트의 후방에 설치되어 도어오픈시나 냉장실 고내온도 상승시에 상기 크로스플로우팬이 급속회전하여 냉기토출구를 통해 증발기에서 생성된 냉기를 고내로 공급하게 된다.In general, the crossflow fan is installed at the upper part of the refrigerating chamber, that is, at the rear of the circulation duct formed along the lower surface of the freezing section of the refrigerator. Cold air is supplied to the inside of the refrigerator.
도 1은 종래 크로스플로우팬의 구조를 나타낸 분리사시도로서, 도면에 도시된 바와 같이, 구동모터(25)는 전후방에 방진고무(80)를 전면고정구(92)와 후면고정구(94)에 개재시켜 모터설치부(60)의 내측에 고정되고, 그 후측으로 후면고정구(94)가 결합되어 볼트고정되며, 중심축(30)에 일정한 간격으로 다수의 지지링(32)이 연설되어 상기 지지링(32)의 테두리를 따라 횡으로 긴 팬날개(35)가 일정각도로 연설된다.1 is an exploded perspective view showing the structure of a conventional crossflow fan, as shown in the drawing, the drive motor 25 is provided with a dustproof rubber 80 in the front and rear 92 and the rear fixture 94 in front and rear It is fixed to the inner side of the motor installation unit 60, the rear fixing tool 94 is bolted to the rear side thereof, a plurality of support rings 32 are addressed to the central axis 30 at regular intervals to the support ring ( The fan blades 35 that are laterally long along the rim of 32 are spoken at a predetermined angle.
또한 상기 팬날개(35)의 길이를 따라 그 후측에 후방커버(50)가 설치된다.In addition, the rear cover 50 is installed on the rear side along the length of the fan blade (35).
한편 상기 모터설치부(60) 반대편의 축고정부(20) 중앙에는 회전팬(40)이 삽입되는 설치공(15)이 형성되고, 상기 축고정부(20)의 외측으로는 베어링(5)이 내설된 방진고무(1)가 강제끼움고정되도록 끼움공(3)이 형성된 금속재질의 고정브라켓(10)이 볼트결합되는데 상기 고정브라켓(10)에 방진고무(1)가 강제끼움고정되고, 회전팬(40)의 중심축(30)은 상기 방진고무(1)의 베어링(5)에 회전가능하게 결합된다.On the other hand, in the center of the shaft fixing part 20 opposite to the motor mounting part 60, an installation hole 15 into which the rotating fan 40 is inserted is formed, and the bearing 5 is installed on the outside of the shaft fixing part 20. The fixing bracket 10 of the metal material having the fitting hole 3 formed thereon is bolted to prevent the dustproof rubber 1 from being forcedly fastened, and the dustproof rubber 1 is forcedly fixed to the fixing bracket 10, and a rotating fan. The central shaft 30 of the 40 is rotatably coupled to the bearing 5 of the anti-vibration rubber 1.
이러한 구성으로 이루어진 종래 크로스플로우팬은 상기 설치공(15)내로 회전팬(40)을 끼워넣어 좌측으로는 구동모터(25)의 회전축과 결합시키고 우측으로는 상기 방진고무(1)내의 베어링(5)에 결합시키며 상기 방진고무(1)를 고정브라켓(10)의 끼움공(3)에 강제끼움결합시켜 고정브라켓(10)의 테두리에 형성된 볼트공(11)에 볼트를 결합함으로써 축고정부(20)에 고정되게 된다.In the conventional crossflow fan having such a configuration, the rotary fan 40 is inserted into the installation hole 15 to the left to engage with the rotation shaft of the drive motor 25, and to the right, the bearing 5 in the anti-vibration rubber 1. ) And the dustproof rubber (1) by forcibly fitting the fitting hole (3) of the fixing bracket (10) by coupling the bolt to the bolt hole (11) formed on the edge of the fixing bracket (10) Will be fixed).

There has been a problem such as to occur.
상기한 문제점을 해결하기 위하여 본 고안 냉장고의 크로스플로우팬은 별도의 고정브라켓을 사용하지 않고 회전팬의 중심축 일측단부를 베어링과 방진고무로서 직접 축고정부에 회전가능하게 고정하고 타측단을 구동모터에 연동되어 회전가능하도록 고정하여 부품수를 줄임은 물론 작업공수를 줄여 생산단가를 낮추고 내식성을 높일 수 있는 크로스플로우팬의 제공을 그 기술적과제로 한다.In order to solve the above problems, the crossflow fan of the present invention refrigerator does not use a separate fixing bracket, and directly rotates one end of the central shaft of the rotating fan to the shaft of the shaft directly as a bearing and dustproof rubber, and drives the other end of the drive motor. The technical challenge is to provide a cross-flow fan that can be fixed in a rotatable way to reduce the number of parts as well as reduce the labor cost and increase the corrosion resistance.
