본 고안은 전자레인지 상방에 설치되어 고주파를 분산시키는 작용을 하는 스티러팬(Stirrer Fan)의 구동장치에 관한 것으로, 특히 고주파 가열에 의해 스티러팬의 카버 또는 샤프트가 변형되는 경우에도 스티러팬이 원활하게 회전될 수 있도록 한 것이다.The present invention relates to a driving device of a stirrer fan which is installed above the microwave oven to disperse high frequency. In particular, the stirrer fan is smooth even when the cover or shaft of the stirrer fan is deformed by high frequency heating. It can be rotated.

일반적으로 전자레인지의 상방에는 스티러팬이 설치되어 있으며 이 스티러팬에 의해 캐비티(Cavity)내로 유입된 고주파를 골고루 분산시켜 음식물이 균일하게 가열되도록 하고 있다.In general, a stirrer fan is installed above the microwave oven, and the food is uniformly heated by uniformly distributing high frequency introduced into the cavity by the stirrer fan.

이러한 작용을 하는 스티러팬을 전자레인지의 상방에 설치하기 위해 종래에는 제3도에 도시한 바와 같이 스티러 캐비티(1)에 샤프트(11)를 고정하여 이 샤프트(11)에 스티러팬(12)의 중심부 부싱(13)을 끼우고 샤프트(11)의 하단부에는 슬라이딩 왓샤(14)와 로크 왓샤(15)를 결합하여 스티러팬(12)이 스티러 캐비티(1)와 팬카버(2) 사이에 위치되게 하였다.In order to install a stirrer pan having such a function above the microwave oven, as shown in FIG. 3, the shaft 11 is fixed to the stirrer cavity 1 and the stirrer pan 12 is attached to the shaft 11. Insert the central bushing (13) of the shaft 11, the lower end of the shaft (11) and the sliding washer (14) and lock washer (15) by combining the stirrer fan 12 between the stirrer cavity (1) and the fan cover (2) Positioned.

즉, 스티러팬(12)을 샤프트(11)에 매어달린 상태로 결합하여 캐비티(1)의 일측으로 부터 유입되는 바람에 의해 스티러팬(12)이 회전하도록 하였으나, 이러한 종래의 장치는 스티러팬(12)과 부싱(13)이 서로 결합된 상태로 함께 회전하는 구조이어서 고주파 가열에 의해 샤프트(11)가 변형되어 어느 일측방향으로 경사지게 기울어지는 경우 부싱(13)의 상단부가 스티러 캐비티(1)에 걸려 로킹(Locking)될 우려가 많고 이러한 경우 스티러팬(12)의 회전이 불가능하게 되어 전자파의 집중현상이 발생하게 되며, 전자파의 집중으로 인해 캐비티 내의 트레이(Tray)가 녹거나 파손되기 쉬운 문제가 있다.That is, the stirrer fan 12 is coupled to the shaft 11 in a suspended state so that the stirrer fan 12 is rotated by the wind flowing from one side of the cavity 1, but such a conventional apparatus is a stirrer fan ( 12) and the bushing 13 are rotated together in a state where they are coupled to each other, so that the shaft 11 is deformed by induction heating and is inclined obliquely in one direction, so that the upper end of the bushing 13 is stirrer cavity 1. In this case, the stirrer fan 12 cannot be rotated, which causes concentration of electromagnetic waves, and concentration of electromagnetic waves tends to melt or break the tray in the cavity. There is.

또 종래의 장치는 스티러팬의 조립을 위해 샤프트를 비롯한 여러 가지의 부수적인 부품이 필요하고 이에따라 조립공정의 증가와 생산성의 저하가 초래되며, 이들 부수적인 부품들에 의해 전체적인 회전기구의 중량이 무거워져 전자레인지에 저전압이 인가되는 경우 스티러팬의 회전작동이 순조롭지 못한 문제도 있다.In addition, the conventional apparatus requires a number of additional parts including a shaft for assembling the stirrer pan, which leads to an increase in the assembly process and a decrease in productivity, and the weight of the entire rotating mechanism is heavy due to these additional parts. When a low voltage is applied to the microwave oven, there is a problem that the rotation operation of the stirrer fan is not smooth.

본고안은 종래의 이와같은 문제점을 해소하기 위한 것으로 스티러팬의 조립에 필요한 부품수를 줄이고 고주파에 의해 회전기구가 가열되는 경우에도 스티러 팬의 회전불능 현상이 일어나지 않도록 한것인바, 이를 첨부된 도면 제1도 내지 제2도에 의해 더욱 상세히 설명하면 다음과 같다.The purpose of this paper is to solve such problems in the related art, and to reduce the number of parts required for assembling the stirrer fan and to prevent the rotator from rotating even when the rotating mechanism is heated by high frequency. More detailed description with reference to FIGS. 1 to 2 as follows.

스티러 캐비티(1)와 팬카버(2) 사이 공간부에 스티러팬을 설치하도록 된것에 있어서, 팬카버(2)에 상향 돌출된 형상의 샤프트부(2a)를 일체로 형성하여 이 샤프트부(2a)의 외주면에 반원형 접속돌기(3a)를 가진 부싱(3)을 결합하고 부싱(3)의 외주면에는 역시 반원형 접속돌기(4a)를 가진 스티러팬(4)을 결합하여 부싱(3)과 스티러팬(4)이 샤프트부(2a)를 축으로 각각 회전할 수 있게 한것이다.In the case where the stirrer fan is provided in the space portion between the stirrer cavity 1 and the fan cover 2, the shaft portion 2a having an upwardly protruding shape is integrally formed on the fan cover 2 and the shaft portion ( A bushing 3 having a semicircular connecting projection 3a is coupled to the outer circumferential surface of 2a) and a stirrer fan 4 having a semicircular connecting projection 4a is also attached to the outer peripheral surface of the bushing 3 to bushing 3 and the It is to allow the rubbing fan 4 to rotate the shaft portion 2a about the shaft, respectively.

도면중 미설명 부호 5는 샤프트부(2a)의 상면에 결합되어 부싱(3)의 접속돌기(3a)와 접속하는 슬라이딩 왓샤이다.In the figure, reference numeral 5 denotes a sliding washer coupled to the upper surface of the shaft portion 2a and connected to the connecting projection 3a of the bushing 3.

이와같이된 구성된 본고안의 스티러팬(4)은 통상의 스티러팬과 같이 캐비티의 일측으로부터 유입되는 바람에 의해 회전하여 고주파를 골고루 분산시키게 되는데, 본 고안에서는 스티러팬(4)이 부싱(3)과 함께 회전하지 않고 이들이 샤프트부(2a)를 중심으로 각각 회전하게 되어 있으므로 통상의 상태에서는 부싱(3)과 스티러팬(4)에 형성된 각 접속돌기(3a)(4a)에 부싱(3)과 스티러팬(4)이 점접촉을 하면서 원활하게 회전될 수 있고, 만약 고주파 가열에 의해 부싱(3)이 변형되어 구속되는 경우에도 스티러팬(4)만이 부싱(3)을 중심으로 하여 회전할 수 있게 되는 것이다.This configuration of the stirrer fan 4 of the present configuration is rotated by the wind flowing from one side of the cavity like a conventional stirrer fan to distribute the high frequency evenly. Since they are rotated about the shaft portion 2a without rotation, the bushing 3 and the stirrer fan are formed in each of the connecting projections 3a and 4a formed in the bushing 3 and the stirrer pan 4 in a normal state. (4) can be smoothly rotated while the point contact, and even if the bushing (3) is deformed and constrained by high frequency heating, only the stirrer fan (4) can be rotated about the bushing (3) will be.

따라서 고주파 열에 의해 부싱과 스티러팬이 구속되어 구주파가 집중되는 현상이 없어지고 이에따른 트레이의 파손을 사전에 예방할 수 있게 된다.Therefore, the bushing and the stirrer pan are constrained by the high frequency heat, and the phenomenon of concentration of the sine wave is eliminated, and thus the damage of the tray can be prevented in advance.

또 샤프트부(2a)가 팬카버(2)에 일체로 형성되어 있고 부싱(3)과 스티러팬(4)이 샤프트부(2a)에 얹혀지는 구조이어서 스티러팬(4)의 조립을 위한 부수적인 부품이 감소되고 조립공정의 단축과 생선성의 향상을 가져오게 되며, 전체 회전기구의 무게가 가벼워져 저전압이 인가되는 경우에도 스티러팬이 원활히 회전될 수 있다.In addition, the shaft portion 2a is integrally formed on the fan cover 2, and the bushing 3 and the stirrer fan 4 are mounted on the shaft portion 2a. Reduced parts, shortening the assembly process and improving the fish properties, the light weight of the entire rotary mechanism can be smoothly rotated even when a low voltage is applied.
