Abstract

본 발명은 가열실내의 턴테이블에 얹혀진 음식물의 양, 크기, 위치에 관계없이 음식물을 조리할 때 음식물에 흡수되지 못하는 잔류 마이크로파에 따라 턴테이블을 상,하 이동시켜 마그네트론에서 발생하는 마이크로파의 효율이 높게 임피던스 정합되도록 하여 음식물 조리시간을 단축시키면서 최적의 음식물 조리상태가 되도록 한 전자레인지의 임피던스 정합장치에 관한 것으로, 종래 전자레인지는 가열실(1)내의 음식물이 조리되도록 마그네트론(5)에서 마이크로파가 발생되면 도파관(7)에 체결된 스터브(8)는 가열실(1)내의 음식물조리상태가 최적의 상태가 되도록 마이크로파와 도파관(7)을 임피던스 정합하지만 가열실(1)내의 음식물 양, 크기 위치에 관계없이 일률적으로 마이크로파를 도파관(7)과 일률적으로 임피던스 정합하여 가열실(1)내로 전송하므로서 최적의 음식물 조리상태를 얻지 못하는 문제점이 있었다. 본 발명은 이와같은 종래 문제점을 해결하기 위하여 가열실내의 턴테이블에 얹혀진 음식물의 양, 크기, 위치에 관계없이 음식물을 조리할 때 음식물에 흡수되지 못하는 잔류 마이크로파에 따라 턴테이블을 상,하 이동시켜 마그네트론에서 발생하는 마이크로파의 효율이 높게 임피던스 정합되도록 하여 음식물 조리시간을 단축시키면서 최적의 음식물 조리상태가 되도록 한 것으로, 전자레인지에 적용한다.In the present invention, regardless of the amount, size, and position of the food placed on the turntable in the heating chamber, the impedance of the microwave generated in the magnetron is increased by moving the turntable up and down according to the residual microwaves that are not absorbed by the food when cooking the food. It relates to an impedance matching device of the microwave oven to match the food cooking time to reduce the food cooking time to match, the conventional microwave oven, when microwave is generated in the magnetron (5) to cook food in the heating chamber (1) The stub 8 fastened to the waveguide 7 impedance-matches the microwave and the waveguide 7 so that the food cooking state in the heating chamber 1 is optimal, but is related to the amount and size of food in the heating chamber 1. Uniformly matches microwaves with the waveguide 7 and transfers them into the heating chamber 1 without Hameuroseo there are problems do not get the best food cooking conditions. The present invention is to solve the above problems in the magnetron by moving the turntable up and down according to the residual microwaves that are not absorbed by the food when cooking the food regardless of the amount, size, and position of the food placed on the turntable in the heating chamber The efficiency of the microwaves is generated so that the impedance matching is high, so that the food cooking time is reduced to the optimum food cooking state, and is applied to a microwave oven.
