Abstract

본 발명은 전자렌인지에서 고주파 에너지를 외부로 방사하도록 전송역할을 하는 안테나 피더와 배기관의 구조에 관한 것으로써, 좀더 구체적으로는 안테나 피더와 배기관의 조립작업시에 안테나 피더가 변형되거나, 위치가 가변되지 않도록 한 것이다. 이를 위해, 안테나 피더(5)의 일단을 베인(8)에 고정하고 상기 안테나 피더의 몸통부위를 애노드 시일(21)의 중심부에 위치되도록 배기관(23)에 조립하여 상부를 팁 오프하도록 된 것에 있어서, 안테나 피더(5)의 몸통부위 및 끝단부를 봉형상으로 하고 상기 안테나 피더의 위치되어 팁 오프되는 배기관(23)은 안테나 피더의 외경보다 약간 큰 소경부(23a)와, 상기 안테나 피더의 의경보다 훨씬 큰 대경부(23b)와, 상기 소경부와 대경부를 연결하는 연결부(23c)로 구성하여 상기 안테나 피더(5)의 상부 끝단이 대경부(23b)를 통해 소경부(23a)의 내부로 삽입되도록 하여서 된 것이다.The present invention relates to a structure of an antenna feeder and an exhaust pipe that transmits high frequency energy to the outside in a microwave oven. More specifically, the antenna feeder is deformed or displaced during assembly of the antenna feeder and the exhaust pipe. It is not to be variable. To this end, one end of the antenna feeder (5) is fixed to the vanes (8) and the body of the antenna feeder is assembled to the exhaust pipe 23 so as to be located in the center of the anode seal 21 to tip off the top The exhaust pipe 23 positioned at the tip of the antenna feeder and tip-off of the trunk portion and the end portion of the antenna feeder 5 is slightly smaller than the outer diameter of the antenna feeder 23a and the diameter of the antenna feeder. It consists of a much larger diameter portion 23b and a connecting portion 23c connecting the small diameter portion and the large diameter portion so that the upper end of the antenna feeder 5 is inserted into the small diameter portion 23a through the large diameter portion 23b. It was made as possible.
