본 고안은 전자레인지의 스터러팬 설치구조에 관한 것으로서, 특히 스터러팬과 축관의 조립을 용이하게 개량한 것에 관한 것이다.The present invention relates to a structure for installing a stirrer pan of a microwave oven, and more particularly, to an easily improved assembly of a stirrer pan and a shaft tube.

일반적으로 도파관을 통해 스터러팬은 마그네트론(magnetron)에서 발생되어 도파관을 통해 캐비티로 유입되는 고주파를 분산시켜 줌으로써 음식물이 골고루 익을 수 있도록 하는 것으로 종래의 스터러팬과 축관은 나사 또는 리벳에 의해 조립되어 캐비티 상판에 설치 고정된 고정축 하부에 결합하도록 되어 있기 때문에 조립이 번거로울 뿐만 아니라 작업시 무리한 힘을 가하다 보면 스터러팬이 변형될 우려가 있었다.In general, a stirrer pan is generated from a magnetron through a waveguide to disperse high frequency waves flowing into the cavity through the waveguide so that food is cooked evenly. Since it is designed to be coupled to the lower part of the fixed shaft fixed to the top plate, the assembly is cumbersome and there is a risk that the stirrer pan may be deformed when the work is applied excessively.

본 고안은 상기의 문제점을 개선하기 위하여 고정축이 끼워지는 축관의 플랜저 외연부에 적정간격을 갖는 걸림편을 형성하고 스터러팬의 결합공 주위에는 상기 걸림편에 대응하는 끼움공 및 걸림부를 형성하여 나사 또는 리벳 없이도 이들을 조립할 수 있도록 함과 아울러 비용을 절감할 수 있도록 한 전자레인지의 스터러팬 설치구조를 제공함에 그 목적이 있다.The present invention is to form a locking piece having an appropriate interval in the flanger outer edge of the shaft tube to which the fixed shaft is fitted in order to improve the above problems and to form a fitting hole and a locking portion corresponding to the locking piece around the coupling hole of the stirrer pan Its purpose is to provide a microwave oven stirrer pan installation structure that allows them to be assembled without screws or rivets and to reduce costs.

이하, 본 고안의 바람직한 한 실시예를 첨부된 도면에 의거하여 상세히 설명하기로 한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

즉 제 1 도에 도시한 바와 같이 캐비티 상판(1)에 고정되는 고정축(2)이 끼워지도록 된 축관(3)이 플랜지(4)를 형성하되, 그 외연부에 적정간격을 두고 걸림편(5)을 하향 형성하는 한편, 스터러팬(6)의 결합공(7) 주위에는 상기 걸림편(5)이 끼워져 걸릴 수 있도록 된 끼움공(8) 및 걸림부(9)를 형성하여서 된 것으로 미설명부호 10은 고정나사이다.That is, as shown in FIG. 1, the shaft tube 3, into which the fixed shaft 2 fixed to the cavity upper plate 1 is fitted, forms a flange 4, but at an outer edge thereof, the locking piece ( 5) is formed downward, while the fitting hole 8 and the locking portion 9 are formed so that the locking piece 5 can be caught around the coupling hole 7 of the stirrer fan 6. Reference numeral 10 is a set screw.

이와 같이 구성된 본 고안은 상기 걸림편(5)이 상기 끼움공(8)의 위치와 일치하도록 하여 축관(3)을 스터러팬(6)의 결합공(7)에 끼운다음 축관(3)을 시계 반대 방향으로 회전시키면 상기 걸림편(5)이 끼움공(8) 일측에 형성된 걸림부(9)를 상호간의 탄력에 의해 극복하면서 이 걸림부(9)의 후면에 걸리게 되어 상기 축관(3)과 스터러팬(6)은 이탈되지 않고 견고한 조립상태를 유지하게 된다.The present invention configured as described above allows the locking piece 5 to coincide with the position of the fitting hole 8 so that the shaft tube 3 is inserted into the coupling hole 7 of the stirrer pan 6 and then the shaft tube 3 is clocked. Rotating in the opposite direction, the locking piece 5 is caught by the rear of the locking portion 9 while overcoming the locking portion 9 formed on one side of the fitting hole 8 by mutual elasticity and the shaft tube 3 and The stirrer fan 6 is not detached to maintain a solid assembly state.

이 상태에서 상기 고정축(2)을 축관(3)에 끼운 다음 고정축(2) 하단에 고정나사(10)를 체결하고 고정축(2) 상부를 캐비티 상판(1)에 고정하게 되면 스터러팬(6)의 설치작업은 완료된다.In this state, the fixed shaft (2) is inserted into the shaft tube (3), and then the fixing screw (10) is fastened to the lower end of the fixed shaft (2) and the upper part of the fixed shaft (2) to the cavity upper plate (1) The installation work in (6) is completed.

이와 같은 본 고안은 스터러팬과 축관을 자체의 결합수단에 의해 조립이 가능하도록 함으로써 조립이 용이할 뿐만 아니라 나사 또는 리벳이 필요 없게 되어 제작비용이 절감되는 잇점이 있는 것이다.The present invention has the advantage that the assembly can be assembled by the coupling means of the stirrer pan and the shaft by not only easy to assemble but also eliminates the need for screws or rivets, thereby reducing the manufacturing cost.
