Abstract

본 발명은 간단한 구성으로 복수의 출사구에서 조사되는 고주파의 강도를 조정할 수 있는 고주파가열장치에 관한 것으로써, 조리실(1)에는 출사구(4)(5)가 설치되어 있고, 도파관(7)은 출사구(4)(5)와 접속되어 있으며, 마크네트론(8)에서의 고주파는 도파관(7)을 통하여 출사구(4)(5)에서 조리실(1)로 조사된다.The present invention relates to a high frequency heating apparatus capable of adjusting the intensity of a high frequency radiated from a plurality of exit ports with a simple configuration. The exit chambers 4 and 5 are provided in the cooking chamber 1, and the waveguide 7 is provided. Is connected to the exit ports 4 and 5, and the high frequency at the macronet 8 is irradiated from the exit ports 4 and 5 to the cooking chamber 1 via the waveguide 7.

도파관(7)의 단부에는 부도파관(9)(10)이 연결되어 있고, 이 부도파관(9)(10)에는 단락면부(13)(14)가 설치되고 제어장치에 의해 이동한다.Sub-waveguides 9 and 10 are connected to the end of the waveguide 7, and the sub-waveguides 9 and 10 are provided with short-circuit surface portions 13 and 14 and are moved by a control device.

마그네트론(8)에서의 고주차는 단락면부(13)(14)에서 반사하기 때문에 그 위치에 따라서 제1, 제2출사구(4)(5)에서 조리실(1)내에 조사되는 고주파의 강도를 의견상 조정할 수 있도록 되어있다.Since the high parking at the magnetron 8 reflects at the short-circuit side portions 13 and 14, the intensity of the high frequency irradiated into the cooking chamber 1 from the first and second exit ports 4 and 5 depending on its position. In the opinion it can be adjusted.
