본 고안은 전자레인지에 관한 것이며, 특히 전자레인지 본체와 문 사이에 형성되는 틈사이로 전파가 누설되는 것을 방지하는 전파누설 방지장치에 관한 것이다.The present invention relates to a microwave oven, and more particularly, to a radio wave leakage preventing device that prevents radio waves from leaking between a gap formed between a microwave oven body and a door.
주지하는 바와 같이 전자레인지는 그 본체와 문 사이의 틈에서 전파가 누설되면 그 전파가 인체에 악영향을 미치며, 또한 전자기기, 통신기기등에 대하여 간섭을 일으켜 통신장애 등을 발생시킨다. 이를 방지하기 위하여 종래에는 제3도에 도시한 바와 같이 전자레인지본체(1)의 가열실(2)에 개폐자재하게 설치되는 문(3)의 주연부에 쵸오크캐비티(4)를 쵸오크캐비티커버(8)로서 덮고 그 커버(8)에 전파흡수체(9)를 설치하여 전자레인지 본체(1)와 문(3) 사이에 형성되는 틈(전파누설통로)에서 전파의 누설을 방지하고 있다. 그러나 전자레인지본체와 문은 방청, 방식을 위하여 도료로서 표면처리를 하고, 또한 전파누설을 방지하기 위하여 별도의 전파흡수체를 쵸오크캐비티등에 설치하였기 때문에 그 생산비가 고가로 되며 생산성도 좋지 못한 결점이있었다.As is well known, when microwaves leak from the gap between the main body and the door, the radio waves adversely affect the human body, and also cause interference with electronic devices, communication devices, and the like. In order to prevent this, the choke cavity cover 4 is provided in the periphery of the door 3, which is conventionally installed in the heating chamber 2 of the microwave oven body 1, as shown in FIG. 3. Covered with (8), a radio wave absorber (9) is provided in the cover (8) to prevent the leakage of radio waves in a gap (propagation leakage passage) formed between the microwave oven main body (1) and the door (3). However, since the microwave oven body and door are surface-treated as paint for antirust and anticorrosion, and a separate electric wave absorber is installed in the choke cavity to prevent radio leakage, the production cost is high and productivity is not good. there was.
본 고안은 위와 같은 결점을 시정하여 문에 표면처리용 도료 또는 유약과 전파흡수재를 혼합한 전파흡수층을 형성하여 그 생산비를 절감하고 생산성도 향상시키며 전파흡수효과도 양호하게 함을 목적으로 한다.The present invention aims to correct the above drawbacks to form a wave absorbing layer of the surface treatment paint or glaze and the wave absorbing material to reduce the production cost, improve productivity and improve the radio wave absorption effect.
본 고안을 실시예도면에 의거 상세히 설명한다.The present invention will be described in detail based on the embodiment drawings.
전자레인지본체(1)에 형성된 가열실(2)의 전면개구부에 문(3)을 개폐가 자유롭게 설치하고 그 문(2)의 주연부에는 쵸오크캐비티(4)를 형성함과 동시에 문(3)의 내부에는 접촉편(6)이 일체로 되고 금망로 된 투시창(7)을 설치하며 쵸오크캐비티(4)에는 쵸오크캐비티커버(8)를 덮은 통상의 전자레인지에 있어서 상기구성의 문을 만든 다음 그 문을 전파흡수재를 혼합한 전파흡수도료 또는 법랑용 유약에 침적하거나 분무방법등에 의하여 문의 전체에 전파흡수층(10)을 형성하여서 된 것이다. 전파흡수층(10)은 상기한 바와 같이 문의 전체에 형성할 수도 있고 또한 쵸오크캐비티(4)의 내벽에만 형성할수도 있으며, 쵸오크캐비티(4)의 내벽과 체결판(6) 또는 문의 주연부 중에서 전파누설통로가 되는 본체(1)와의 접촉부에만 1개소 이상 형성될 수도 있다.The door 3 is freely opened and closed at the front opening of the heating chamber 2 formed in the microwave oven body 1, and the choke cavity 4 is formed at the periphery of the door 2. In the inside of the contact piece (6) is integrally provided with a gold mesh see-through window (7) and the choke cavity (4) made of a door of the above configuration in a conventional microwave oven covered with the choke cavity cover (8) Next, the door is formed by mixing the radio wave absorbing material or enamel glaze mixed with the radio wave absorber or by forming a radio wave absorption layer 10 on the entire door by a spraying method. The electromagnetic wave absorbing layer 10 may be formed in the entire door as described above, or may be formed only in the inner wall of the choke cavity 4, and among the inner wall of the choke cavity 4 and the fastening plate 6 or the periphery of the door. One or more places may be formed only at the contact portion with the main body 1 serving as the radio wave leakage passage.
또한 상기한 전파흡수재는 페라이트와 같은 자성재료, 카본과 같은 도전재료, 티탄산바륨과 같은 유전재료를 1종 이상 포함한 것이 사용되며 다른 전파흡수재도 사용될 수 있다.In addition, the radio wave absorber may include a magnetic material such as ferrite, a conductive material such as carbon, and one or more kinds of dielectric materials such as barium titanate. Other radio wave absorbers may be used.
미설명부호 5는 체결편이다.Reference numeral 5 is a fastening piece.
이상과 같은 본 고안은 가열실(2)에서 본체(1)와 문(3)의 틈(전파누설통로) 사이로 진입되는 전파는 접촉편(6)에서 일부가 흡수되고 나머지는 료오크캐비티 커버(8)를 통하여 쵸오크캐비티(4)에 진입되어 그 내벽에 형성된 전파흡수(10)에서 흡수되고 나머지 전파는 가열실(2)에 다시 되돌아가며 가열실(2)에 되돌아가지 못한 전파는 전파누설통로에 형성된 전파흡수층에서 흡수되는 것이다.The present invention as described above is a part of the radio wave entering the gap between the main body 1 and the door (propagation leakage passage) in the heating chamber (2) is absorbed in the contact piece (6) and the rest of the ryok cavity cover ( 8) through the choke cavity (4) enters and absorbs in the radio wave absorption (10) formed on the inner wall and the remaining radio waves are returned to the heating chamber (2) again, the radio waves not returned to the heating chamber (2) It is absorbed by the radio wave absorption layer formed in the passage.
이상과 같이 본 고안은 문을 형성한 후 그 문의 전체 또는 일부(쵸오크캐비티(4)의 내벽, 쵸오크캐비티(4)의 내벽과 접촉편 또는 쵸오크캐비티(4) 내벽과 문의 주연부 중 본체(1)와의 접촉부등)에만 도료 또는 유약에 전파 흡수재를 혼합한 전파흡수층을 형성하므로서 종래와 같이 문에 도료를 도포한 다음 별도의 전파흡수체를 설치하던것에 비하여 그 부품수도 적어도 제조공정이 단순화되어 생산성이 향상되고 또한 접촉편과 문의 주연부 중 본체와 접촉부에서도 전파흡수가 가능하므로 전파흡수효과가 양호한 것이다.As described above, after the door is formed, the present invention includes the whole or part of the door (inner wall of the choke cavity 4, inner wall and contact piece of the choke cavity 4, or main body of the inner wall of the choke cavity 4 and the peripheral part of the door). (1) the radio wave absorbing layer in which the radio wave absorber is mixed with the paint or the glaze is formed only on the part, and the manufacturing process is simplified at least in the number of parts compared with the conventional application of the paint to the door and then the installation of a separate radio wave absorber. Since the productivity is improved and the radio wave can be absorbed by the main body and the contact part of the contact piece and the peripheral part of the door, the radio wave absorption effect is good.
