Abstract

본 발명은 전자레인지의 도어 힌지 구조에 관한 것으로, 종래의 전자레인지의 도어 힌지 구조는 힌지판이 상차측으로 분리되어 있어 부품수가 많아져 조립시 작업공정이 많고, 재료비가 상승되는 등의 문제가 있고, 또한 도어(8)의 상단부에 조립되는 힌지핀(6)은 별도의 브라켓트(9)가 도어(8)에 용접된 상태에서 조립되는 것이므로 상부 힌지판(2)의 힌지공(2a)과, 하부 힌지판(3)의 힌지핀(3a)의 위치가 편심되기 쉬워 조립이 어려운 문제가 있는 바, 캐비티(11)에 고정되는 힌지판(12)의 상하판을 일체로 형성하여 도어측 또는 힌지판 중 일측에 힌지핀 또는 힌지공을 형성하며, 타측에 힌지핀 또는 힌지공을 형성하여 결합이 한 번에 이루어져 조립 작업이 간소화됨으로써 작업생산성이 향상되며, 특히 가조립 단계가 없어 조립작업이 용이하게 이루어지는 효과가 있고, 힌지판이 상하 일체형이기 때문에 조립작업시 발생되기 쉬운 상하측 힌지공의 편심을 방지하도록 한 것이다.The present invention relates to a door hinge structure of a microwave oven, the door hinge structure of a conventional microwave oven has a problem that the hinge plate is separated to the vehicle side, the number of parts increases, there is a lot of work processes when assembling, the material cost increases, In addition, the hinge pin 6 assembled to the upper end of the door 8 is assembled in a state in which a separate bracket 9 is welded to the door 8, so that the hinge hole 2a of the upper hinge plate 2 and the lower part Since the position of the hinge pin 3a of the hinge plate 3 tends to be eccentric and difficult to assemble, the upper and lower plates of the hinge plate 12 fixed to the cavity 11 are integrally formed so that the door side or the hinge plate is integrally formed. The hinge pin or the hinge hole is formed on one side of the hinge, and the hinge pin or the hinge hole is formed on the other side, so that the assembly work is simplified by simplifying the assembly work. Filial piety And, because the hinge plate is vertically integrated, it is to prevent the eccentricity of the upper and lower hinge holes that are likely to occur during assembly work.
