본 고안은 전자레인지(microwave oven)에 관한 것으로 보다 구체적으로는 그 전파누설 방지구조에 관한 것이다.The present invention relates to a microwave oven (more specifically, to a radio wave leakage prevention structure).

일반적으로 전자레인지는 극초단파등의 전파로 음식물을 자체발열시켜 조리하는 장치인데, 음식물의 조리시 인체에 유해한 전파가 밖으로 누설되지 않도록 해주기 위하여 도어의 투명창 후면에 전파차폐용 스크린등 전파 누설 방지수단을 구비하고 있다.In general, a microwave oven is a device that heats food by itself by microwave waves, and prevents leakage of radio waves, such as a screen for shielding radio waves on the rear of the transparent window of the door so that harmful waves do not leak outside when cooking food. Equipped with.

그러나 종래의 전자레인지는 제3도에 도시된 바와같이 가열실(12)을 차폐하는 도어(13)가 케이싱(casing)의 전판(14)과 단순히 평면 접촉하는 구성이므로 그 접촉부에 전파흡수용 패킹(packing)등과 같은 차폐수단을 구비한다 하더라도, 전판(14)이 변형되거나 도어(13)의 평탄도가 일정치 않은 경우에는 전파가 쉽게 누설되는 문제점이 있었다.However, in the conventional microwave oven, as shown in FIG. 3, since the door 13 shielding the heating chamber 12 is simply configured to be in flat contact with the front plate 14 of the casing, the packing for absorbing radio waves at the contact portion thereof. Even if a shielding means such as packing or the like is provided, radio waves easily leak when the front plate 14 is deformed or the flatness of the door 13 is not constant.

상술한 종래의 문제점을 감안하여 본 고안은 전판이나 도어가 변형되더라도 전파가 누설되지 않는 전파누설 방지구조를 제공하는 것을 목적으로 한다.In view of the above-described conventional problems, the present invention aims to provide a radio wave leakage prevention structure in which radio waves are not leaked even if a front plate or a door is deformed.

이러한 목적을 달성하기 위해 본 고안에 의한 전판누설 방지구조는 도어의 둘레에 돌출턱을 형성하고 전판에 이에 대응하는 인입홈을 형성하여 도어의 폐쇄시 이 돌출턱과 인입홈이 서로 맞추어 짐으로써 전파누설을 차단하는 것을 특징으로 한다.To achieve this purpose, the front plate leakage prevention structure according to the present invention forms a protruding jaw around the door and forms an inlet groove corresponding to the front plate so that the protruding jaw and the inlet groove are aligned with each other when the door is closed. It is characterized by blocking the leakage.

본 고안의 한 특징에 의하면 이 돌출턱 및 인임홈은 다단(多段)으로 구성되어 전파누설을 더욱 확실히 차단할 수 있게 된다.According to one feature of the present invention, the protruding jaw and the recess groove are configured in multiple stages to more reliably block radio leakage.

이하 첨부된 도면을 참조하여 본 고안의 한 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도에서, 전자레인지의 본체(1)내에는 가열실(2)이 구비되어 음식물이 트레이(tray)등에 얹혀 조리된다.In FIG. 1, the heating chamber 2 is provided in the main body 1 of the microwave oven, and food is cooked on a tray or the like.

가열실(2)을 폐쇄하는 도어(3)의 내측에는 본 고안 특징에 따라 그 둘레에 가열실(2)측으로 돌출하는 돌출턱(5)이 형성되고 가열실(2)의 외주를 이루며 도어(3)에 접촉하는 본체(1)의 전판(4)에는 도어(3)의 돌출턱(5)에 대응하는 인입홈(6)이 형성된다.In the interior of the door 3 to close the heating chamber (2) in accordance with the features of the present invention is formed a protruding jaw (5) protruding toward the heating chamber (2) around the periphery of the heating chamber (2) to form a door ( An inlet groove 6 corresponding to the protruding jaw 5 of the door 3 is formed in the front plate 4 of the main body 1 in contact with 3).

도어(3)의 돌출턱(5)과 전판(4)의 인입홈(6)은 도어(3)의 폐쇄시 서로 맞물리게 되어, 그 사이의 접촉면은 종래와 같이 평면이 아니라 지그재그(zig-zag)형의 경로를 이루게 된다.The protruding jaw 5 of the door 3 and the retracting groove 6 of the front plate 4 are engaged with each other when the door 3 is closed, so that the contact surface therebetween is not flat but is zigzag (zag-zag) as before. The path of the type is achieved.

이에 따라 전판(4)이 변형되거나 도어(1)의 평탄도가 불량한 경우에도 그 사이의 경로가 지그재그로 굴곡되므로 전파는 외부로 누설되기 어렵게 된다.Accordingly, even when the front plate 4 is deformed or the flatness of the door 1 is poor, the path between them bends zigzag, so that radio waves are less likely to leak to the outside.

바람직하기로 돌출턱(5)과 인입홉(6)은 제1도, 특히 제2도에 잘 도시된 바와같이 다단으로 구성된다.Preferably, the protruding jaw 5 and the retracting hop 6 are configured in multiple stages as well shown in FIG. 1, in particular in FIG. 2.

이에 따라 도어(3)와 전판(4)간의 접촉면이 더욱 복잡한 경로를 그리게 되어 수십cm정도의 파장을 가지는 전파는 외부누설이 거의 이루어지지 않고 차단된다.Accordingly, the contact surface between the door 3 and the front plate 4 draws a more complicated path, and radio waves having a wavelength of about several tens of centimeters are blocked with little external leakage.

또한 이와같은 도어(3)의 돌출턱(5)과 전파(4)의 인입홈(6)은 도어(3)와 전판(4)의 강성(剛性)을 현저히 증가시키게 되므로, 도어(3)와 전판(4)은 제작이나 사용중의 외력의 인가에 의해 쉽게 변형되지 않게 된다.In addition, the protruding jaw 5 of the door 3 and the inlet groove 6 of the radio wave 4 significantly increase the rigidity of the door 3 and the front plate 4, and thus, the door 3 and the door 3. The front plate 4 is not easily deformed by the application of an external force during manufacture or use.

따라서 제조공정상의 불량이 방지되고 조립성등이 향상되는 구조상의 이점도 가지게 된다.Therefore, there is also a structural advantage that the defects in the manufacturing process is prevented and the assembly properties are improved.

상술한 바와같이 본 고안에 의하면 전파누설이 완전히 차폐될수 있는 전자레인지를 우수한 품질과 생산성으로 제공할 수 있게된다.As described above, according to the present invention, it is possible to provide a microwave oven in which radio leakage can be completely shielded with excellent quality and productivity.
