Abstract

본 발명은 전자레인지의 전자파 누설방지장치에 관한 것으로, 도어프레임(30)의 연결수직면(31)에 일체로 절곡형성되어 쵸크채널(41)을 형성하는 쵸크부(40)의 내측쵸크수직면(46)에 단차부(47)와 슬롯트(48)를 주기적으로 형성하는 전자파 누설방지장치에 있어서, 상기 단차부(47)는 전편판넬(21)과 평행하게 마주보는 내측 쵸크수직면(46)에서 쵸크채널(41)의 내측으로 직각절곡된 제1수평단차(47a)와, 상기 제1수평단차(47a)에서 상기 내측쇼크수직면(46)과 평행하게 쵸크채널(41)의 내측으로 직각절곡되는 수직단차(47b)와, 상기 수직단차(47b)에서 외측쵸크수직면(44)으로 직각절곡되는 제2수평단차(47c)로 구성되며, 상기 슬롯트(48)는 상기 내측쵸크수직면(46)의 말단인 상기 제1수평단차(47a)에서부터 형성된다. 상기와 같은 본 발명에 의한 전자레인지의 전자파 누설 방지장치에 의하면 슬롯트의 폭을 조절하여 쵸크채널의 두께를 얇게하면서도 전자파차단특성이 향상되어 조리실의 용량을 증가시킬 수 있는 이점이 있다.The present invention relates to a microwave leakage preventing device of a microwave oven, the inner choke vertical surface 46 of the choke portion (40) forming the choke channel (41) formed integrally bent to the connection vertical surface 31 of the door frame (30). In the electromagnetic leakage preventing device for periodically forming the step portion 47 and the slot 48 in the step, the step portion 47 is choked on the inner choke vertical surface 46 facing in parallel with the front panel 21 A first horizontal step 47a bent at an angle to the inside of the channel 41 and a vertical angle bent perpendicularly to the choke channel 41 in parallel with the inner shock vertical surface 46 at the first horizontal step 47a. A step 47b and a second horizontal step 47c bent at right angles from the vertical step 47b to the outer choke vertical surface 44, wherein the slot 48 is an end of the inner choke vertical surface 46; Is formed from the first horizontal step 47a. According to the microwave leakage preventing device of the microwave oven according to the present invention as described above, the width of the choke channel is reduced by adjusting the width of the slot, and the electromagnetic wave blocking property is improved, thereby increasing the capacity of the cooking chamber.
