본 고안은 전자레인지의 스터러팬 고정 부싱에 관한 것으로 특히 고회전 및 안정된 회전을 하기에 적당한 구조로 이루어진 전자레인지의 스터러 팬 고정 부싱에 관한 것이다. 종래의 스터퍼랜은 제 1 도의 설치상태 단면도에서와 같이 캐비티(1)의 상측면에 스터러팬용 지지축(8)을 너트(8a)로 고정시키고, 스터퍼팬(2)은 부싱(11)에 코오킹으로 고정시켜서 지지축(8)에 부싱(4)을 끼우면서 부싱(4)과 지지축(8) 사이에 슬라이딩 부싱(5)을 삽입하고 부싱(4)이 이탈되지 않도록 지지축(8) 하단에 슬라이딩 와셔(6)와 고정와서(7)를 끼웠다.The present invention relates to a stirrer fan fixed bushing of a microwave oven, and more particularly, to a stirrer fan fixed bushing of a microwave oven having a structure suitable for high rotation and stable rotation. In the conventional stuffer lan, the stirrer pan support shaft 8 is fixed to the upper side of the cavity 1 with the nut 8a as shown in the installation state sectional view of FIG. 1, and the stuffer pan 2 is attached to the bushing 11. The sliding shaft 5 is inserted between the bushing 4 and the support shaft 8 while the bushing 4 is fixed to the support shaft 8 by fixing by caulking, and the support shaft 8 is not detached from the bushing 4. ) Put the sliding washer (6) and the fixed washer (7) at the bottom.

이와같이 설치된 스터러팬의 회전속에 따라 음식물의 익는 정도가 다른 것으로 즉, 회전수가 어느정도 이상일때 까지는 회전수가 많으면 좋고 또 초기 가동시 정격(120V 60HZ) 미만일때에는 에어가 적게 들어가기 때문에 기동이 되지 않아 국부적으로 집중가열 되어 음식이 타버리는 경우도 있다.The degree of ripening of food is different according to the rotation speed of the installed stirrer fan. That is, the rotation speed should be higher until the rotation speed is higher than a certain number. In some cases, the food will burn when heated.

또한, 종래의 스터러팬 구조는 지지축과의 면접촉 상태로 회전하기 때문에 마찰저항이 커서 초기 기동 및 회전수에 많은 무리가 있었던 것이다.In addition, the conventional stirrer fan structure rotates in the surface contact state with the support shaft, so that the frictional resistance is large, and there is a lot of difficulties in the initial start and rotation speed.

이러한 문제점을 해결하기 위해 안출한 본 고안은 스터러팬의 회전시 발생되는 마찰저항은 최소하게 형성하여 회전력을 증가시킬 뿐만 아니라 스터퍼팬이 좌우 유동하지 않게 하는 것으로 본 고안을 첨부 도면과 함께 상세하게 설명하면 다음과 같다.The present invention devised to solve such a problem is described in detail with the accompanying drawings that the friction resistance generated during the rotation of the stirrer fan to minimize the increase in the rotational force and the stuffer fan does not flow left and right. Is as follows.

제 2 도는 본 고안에 따른 스터러팬의 설치상태 단면도인 것으로 캐비티(9)에 지지축(10)을 끼워 통상의 너트(9a)로 고정하고, 지지축(10)에는 부싱(11)을 끼우되 부싱(11)에 스터러팬(13)을 삽입하여 일체로 돌출시켜 탄성을 함유한 고정편(12)과 받침편(12') 사이에 고정하고, 부싱(11)의 선단(11a)의 원추형상을 이루게 하여 상기의 지지축(10)에 부싱의 내경(11b)을 깊게끼우고 자체의 하중으로 스터러 카바(14)의 상면과 선단(11a)이 점접촉을 이루게 한다.2 is a cross-sectional view of the installation state of the stirrer pan according to the present invention, the support shaft 10 is inserted into the cavity 9 and fixed with a normal nut 9a, and the bushing 11 is inserted into the support shaft 10. The stirrer pan 13 is inserted into the bushing 11 to protrude integrally and is fixed between the fixing piece 12 and the supporting piece 12 'containing elasticity, and the conical shape of the tip 11a of the bushing 11 is fixed. The inner diameter 11b of the bushing is deeply inserted into the support shaft 10, and the top surface of the stirrer cover 14 and the tip 11a are in point contact with their own load.

이러한 구성으로 이루어진 본 고안은 공기가 전자레인지의 강제송풍장치에 의해 스터러 카바(14)내로 들어오면 스터러팬(13)의 날개에 부딪혀 스터퍼팬(13)에 힘을 가한다. 이때 공기의 힘이 지지축(10)의 삽입된 길이(ℓ)에서의 접촉저항과 선단(11a)의 점접촉 저항보다 크면 스터러팬(13)을 회전하게 되나 실질적으로 이들의 접촉저항은 매우적어서 적은 힘의 공기가 유입되어도 용이하게 회전하게 되고 또한 회전초기에 부싱(11) 선단(11a)의 저항이 매우적으므로 초기 기동이 종래보다 쉽게 이루어지는 작용이 이루어지고 지지축의 삽입길이가 길어서 초기기동시 스터러팬이 좌우로 기울어지는 현상이 최소화된다.According to the present invention having such a configuration, when air enters into the stirrer cover 14 by the forced blower of the microwave oven, the impingement of the stuffer fan 13 is applied to the wings of the stirrer fan 13. At this time, if the air force is greater than the contact resistance at the inserted length ℓ of the support shaft 10 and the point contact resistance of the tip 11a, the stirrer fan 13 is rotated, but the contact resistance thereof is very small. Even when a small amount of air flows in, it easily rotates, and since the resistance of the tip 11a of the bushing 11 is very small at the beginning of rotation, the initial starting is made easier than before, and the insertion length of the support shaft is long, so that the initial starting Minimization of the tilt of the stirrer pan from side to side.

이상에서와 같이 본 고안은 부싱자체의 구성만으로 스터러팬을 간단히 고정할 수 있는 효과와 조립구조가 간단해 누구나 용이하게 조립할 수 있는 생산성의 향상 효과가 나타나는 것이고 저전압에서의 스터러팬의 초기기동이 양호하고 스터러팬의 마찰저항을 줄여 회전수의 증가로 인해 균일가열효과를 증대시킬 수 있는 기동성의 향상효과를 볼수 있는 고안인 것이다.As described above, the present invention has the effect of simply fixing the stirrer pan by the configuration of the bushing itself, and the assembly structure is simple, so that the productivity improvement effect can be easily assembled by anyone, and the initial startup of the stirrer fan is good at low voltage. It is designed to see the improvement of maneuverability which can increase the uniform heating effect by increasing the rotational speed by reducing the frictional resistance of the stirrer fan.
