본 고안은 전자레인지의 전파누설방지 장치의 개량에 관한 것이다.The present invention relates to an improvement of a radio wave leakage prevention apparatus of a microwave oven.
전자레인지의 본체와 문짝사이의 간극으로부터 전파가 누설되면 이 전파가 인체에 악영향을 미칠뿐만아니라 라디오, 텔레비젼, 콤퓨터에 간섭을 일으키거나 각종 통신장애를 발생시킨다.The leakage of radio waves from the gap between the main body and the door of the microwave oven not only adversely affects the human body, but also causes interference with radios, televisions, computers, and various communication disturbances.
상기한 전파의 불필요한 누설을 방지하기 위하여 일반적으로 쵸오크 캐비타의 개구부에 합성수지로 된 쵸오크캐비티 커버를 덮고 쵸오크캐비티의 내측 외주부등에 쵸오크캐비티 커버와는 별도로 만든 전파흡수체를 내측 외주부등에 쵸오크캐비티 커버와는 별도로 만든 전파흡수체를 설치하여서 전파를 흡수하여 본체와 문짝사이에서의 전파누설을 방지하고 있다.In order to prevent unnecessary leakage of the above-mentioned electric wave, cover the choke cavity cover made of synthetic resin in the opening of the choke cavity and cover the inside of the choke cavity with the electric wave absorber made separately from the chock cavity cover. A radio wave absorber, which is made separately from the oak cavity cover, is installed to absorb radio waves to prevent leakage between the body and the door.
또한 최근에 와서는 종래 쵸오크캐비티 커버와 전파흡수체가 각각 별도로 되어 있어서 조립비용의 증가등의 이유로 제3도와 같이 쵸오크캐비티의 개구부에 쵸오크캐비티 커버와 전파흡수를 겸하는 전파흡수판을 덮고 있다. 그러나 이것은 조립비용의 감소등은 해결되었으나 가열실의 발생열에 의하여 전파흡수판이 변형될 뿐만 아니라 전파흡수 효과가 떨어져 본체와 문짝 사이로 전파가 누설될 염려가 있고 문짝 외주연부와 전파흡수판의 사이로 국물, 음식 찌거기등의 오물이 쵸오크캐비티에 들어가거나 문짝주연부와 전파흡수판 사이에 끼워 불결한 점등이 있었다.In addition, in recent years, the conventional choke cavity cover and the radio absorber are separately provided so that the opening of the choke cavity covers the electric wave absorbing plate which serves as the choke cavity cover and the electric wave absorption as shown in FIG. . However, this has solved the reduction of the assembly cost, but the radio wave absorbing plate is not only deformed by the generated heat of the heating chamber, but the radio wave absorbing effect may be reduced, causing radio waves to leak between the main body and the door. Dirt, such as food debris, entered the chock cavity or was caught between the perimeter of the door and the radio wave absorption plate, resulting in dirty lighting.
본 고안은 상기한 결점을 개량하여 전파흡수판의 설치를 견고하게 하고 전파흡수효과가 떨어지는 것을 방지하며 오물이 끼는것등을 방지하기 위한 것을 특징으로 한다.The present invention is characterized in that to improve the above-mentioned defects to strengthen the installation of the radio wave absorption plate, to prevent the radio wave absorption effect is lowered, and to prevent contamination.
본 고안은 상기한 목적을 달성하기 위하여 쵸오크캐비티 커버를 겸하는 전파흡수판의 외주연부에 후육부를 일체로 형성하고 후육부에 홈을 설치하여 이 홈을 문짝주연부에 끼우도록 한것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that the thick portion is integrally formed at the outer circumferential edge of the radio wave absorbing plate which serves as the choke cavity cover, and the groove is fitted to the edge of the door by installing the groove in the thick portion. .
이하 실시예 도면에 의하여 상세히 설명한다.Hereinafter will be described in detail with reference to the accompanying drawings.
본체(1)에 가열실(3)을 형성하고 가열실(3)의 전면에 개폐가 자유롭게 문짝(4)을 설치하여 그의 전주면에 쵸오크캐비티(6)를 형성하며 쵸오크캐비티의 개구부(6')에 쵸오크캐비티커버를 겸하는 전파흡수판(7)을 덮은 통상의 것에 있어서 전파흡수판(7)의 외주연부에 후육부(8)을 일체로 형성하고 후육부(8)에 홈(9)을 설치하여 이 홈을 문짝(4)의 주연부에 끼우도록 한것이다.The heating chamber 3 is formed in the main body 1, the door 4 is opened and closed freely in the front of the heating chamber 3, and the choke cavity 6 is formed on the front circumference thereof, and the opening of the choke cavity ( 6 '), the thick part 8 is integrally formed on the outer periphery of the radio wave absorbing plate 7 in the ordinary thing covering the electric wave absorbing plate 7 serving as the choke cavity cover. 9) to install this groove to the periphery of the door (4).
상기한 전파흡수판(7)은 공지한 카본전파흡수재, 페라이트전파 흡수재 및 카본과 페라이트를 혼합한 전파흡수재로 만든것을 사용한다.The radio wave absorbing plate 7 is made of a known carbon wave absorber, a ferrite wave absorber, and a wave absorber mixed with carbon and ferrite.
미 설명부호 2는 본체의 전면부, 5는 금망(차폐판), 10,10'는 화장판이다.Reference numeral 2 is a front portion of the main body, 5 is a gold screen (shield plate), 10, 10 'is a decorative plate.
이상과 같은 본 고안의 전파누설방지 기능은 문짝(4)과 본체(1)의 전면부(2) 사이로 누설되는 전파가 쵸오크캐비티(6)의 작용에 의하여 감쇠되고, 일부는 본체(1)와 문짝(4)의 간극으로 진행하다가 전파흡수판(7)및 후육부(8)에 흡수되는 것이다.The propagation leakage prevention function of the present invention as described above is attenuated by the action of the choke cavity 6, the radio wave leaked between the front door 2 of the door 4 and the main body 1, a part of the main body (1) Proceeding to the gap between the and door (4) is absorbed by the radio wave absorption plate 7 and the thick portion (8).
이상과 같은 본 고안은 전파흡수판(7)의 외주연부에 후육부(8)를 일체로 형성하였으므로 전파흡수기능을 보완하므로서 전파흡수성능이 향상되어 전파의 누설을 완전히 방지하고, 후육부(8)에 홈(9)을 설칭하여 이홈을 문짝(4)의 주연부에 끼웠으므로 그 설치가 견고하여 가열실의 발생열에 의하여도 전파흡수판(7)이 변형됨을 방지할 뿐만아니라 오물이 문짝의 주연부와 전파흡수판 사이에 끼는것과 쵸오크캐비티에 들어가는 것이 방지되므로 위생상 청결한 효과등이 있다.In the present invention as described above, since the thick portion 8 is integrally formed on the outer periphery of the radio wave absorbing plate 7, the radio wave absorbing function is improved, thereby improving the radio wave absorbing performance to completely prevent the leakage of radio waves, and the thick portion 8 The grooves 9 are installed at the periphery of the door 4 so that the installation is firm and prevents the radio wave absorbing plate 7 from being deformed by the heat generated in the heating chamber. It is prevented from being caught between and the radio wave absorption plate and entering into the choke cavity, so there is a sanitary clean effect.
