Abstract

본 발명은 전자레인지의 턴테이블 회전 및 승강 장치에 관한 것으로, 종래 전자레인지의 턴테이블 회전구조는 턴테이블(3)을 단순히 회전시키는데 불과하여 요리물이 마이크로 웨이브에 균일하게 조사되지 못하는 단계가 있고, 열원에 의한 그릴요리시에도 요리물이 열원과 일정한 거리를 가지고 있기 때문에 조리속도가 느리고, 조리의 질이 떨어지는 결함이 있는 바, 구동원이 모터(11)의 축(12)에 턴테이블(13)이 회전가능하게 고정되어 있고, 상기 모터(11)는 브라켓(14)에 의해 하부 플레이트(15)에 지지고정되어 있는 종래의 전자레인지의 턴테이블 회전구조에서 상기 모터고정브라켓(14)의 내측에 아웃 가이드(16)를 고정하고, 모터축(12)의 회전에 의해 회전되어 상기 아웃 가이드(16)의 내주면에 형성된 안내돌기(16a)에 안내되면서 승강되는 인너 가이드(18)와, 상기 인너 가이드(18)와 턴테이블축(13a)을 연결지지하는 서포터(19)와, 상기 인너 가이드(18)를 모터축(12)에 고정시키는 고정핀(20)이 설치되는 본 발명을 제공하여 단순히 턴테이블의 회전 뿐 아니라 승강동작이 동시에 이루어지므로 요리물에 마이크로 웨이브가 균일하게 조사되며, 열원에도 근접하게 움직이게 되어 요리물의 조리시간이 단축되고, 조리물의 질이 향상되도록 한 것이다.The present invention relates to a turntable rotating and elevating device of a microwave oven, and the turntable rotating structure of a conventional microwave oven merely rotates the turntable 3, so that food is not uniformly irradiated with microwaves, Even when the grill is cooked, since the food has a certain distance from the heat source, the cooking speed is slow and the quality of the cooking is poor. As a result, the drive source can rotate the turntable 13 on the shaft 12 of the motor 11. The motor 11 is fixed to the lower plate 15 by the bracket 14, and the out guide 16 inside the motor fixing bracket 14 in a turntable rotating structure of a conventional microwave oven. Inner guide 18 which is fixed and, which is rotated by the rotation of the motor shaft 12 and guided to the guide protrusion 16a formed on the inner circumferential surface of the out guide 16, is elevated. ), A supporter 19 for supporting the inner guide 18 and the turntable shaft 13a, and a fixing pin 20 for fixing the inner guide 18 to the motor shaft 12 is provided. By providing a simple rotation of the turntable as well as the lifting operation is made at the same time because the microwave is uniformly irradiated to the food, move closer to the heat source to reduce the cooking time of the food, and to improve the quality of the food.
