*도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 전자렌지도아 2 : 고주파차단판1: microwave oven 2: high frequency blocking plate
3 : 단층면 4 : 캐비티3: single-sided surface 4: cavity
5 : 조리실5: cooking chamber
본 고안은 전자렌지도아 후면에 융기된 고주파 차단판을 부설하여 캐비티 전면에 밀착되도록 도아를 개량한 고주파차단용 전자렌지도아장치에 관한 것이다.The present invention relates to a microwave oven device for high-frequency cut off by improving the door to be in close contact with the cavity front by placing a high frequency blocking plate raised on the rear of the microwave oven.
일반적으로 전자렌지의 누설전파를 방지하기 위하여는 도아쵸크의 구조가 ㅅ/4≒30.61㎜로 된 것을 사용해야 한다.In general, to prevent the leakage propagation of the microwave oven, the structure of the doach choke should be used to be S / 4 ≒ 30.61㎜.
또한 잔류고주파를 누설은 캐비티면과 도아밀착면의 면적이 클수록 유리하다.In addition, the leakage of residual high frequency is advantageous as the area of the cavity surface and the door contact surface becomes larger.
그러나 종래의 도아구조는 개키티전면에만 도아의 고주파 차단판이 밀착된 상태로써 밀착면이 협소하고 도아 자체가 상하좌우로 유동되기 때문에 캐비티와 도아쵸크 사이에 공극이 생겨 이로 말미암아 누설전파가 새어나오는 성능상의 결함이 있었다. 또한 전자렌지 도아의 유동에 따른 후크부의 안전스위치가 작동되지 않아 전자레ㅐㄴ지의 기능이 저하되는 단점이 있다.However, in the conventional door structure, the high frequency blocking plate of the door is in close contact with only the front surface of Gakitty, and the contact surface is narrow and the door itself flows up, down, left, and right, so that a gap is generated between the cavity and the door choke, which causes leakage propagation. Was defective. In addition, there is a disadvantage in that the function of the microwave oven is deteriorated because the safety switch of the hook portion according to the flow of the microwave oven is not operated.
본 고안은 이와 같은 단점을 개선하기 위하여 도아후면에 융기는 고주파 차단판을 설치하여 전자렌지 캐비티와의 접촉면을 증대시킴으로써 누설전파를 확실히 차단할 수 있는 도아를 제공하는데 있다.The present invention is to provide a door that can block the leakage propagation by increasing the contact surface with the microwave cavity by installing a high-frequency blocking plate on the back of the door to improve such disadvantages.
본 고안의 또 다른 목적은 상ㅇ기 고주파 차단판이 전자렌지 캐비티내에 어느 정도 삽입되어 밀착되는 관계로 도아의 유동을 방지하는 구조를 제공함과 아울러 도아에 부착된 앉스위치의 작동을 확실하게 하는데 있다.Another object of the present invention is to provide a structure to prevent the flow of the door as the high frequency blocking plate is inserted into the microwave cavity to some extent and to ensure the operation of the seat switch attached to the door.
이하 본 고안을 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
즉 제 1도는 본 고안의 고주파 차단판을 전자렌지도어 후면에 부착한 상태를 도시한 것으로 도아(1) 후면으로 캐비티(4)의 조리실(5)크기와 동일한 고주파 차단판(2)을 부착하여 상기 고자푸차단판(2)의 절곡된 단층면(3)이 조리실(5) 내부로 약간 삽입되어 캐비티(4)와의 접촉면적을 증대시켜 누설전파를 억제하는데 있다.1 shows a state in which the high frequency blocking plate of the present invention is attached to the rear of the microwave oven, and the same high frequency blocking plate 2 as the size of the cooking chamber 5 of the cavity 4 is attached to the rear side of the oven 1. The bent tomographic surface 3 of the gojapu barrier plate 2 is slightly inserted into the cooking chamber 5 to increase the contact area with the cavity 4 to suppress leakage propagation.
제 2도는 도아를 닫았을 때 고주파 차단판의 주연과 캐비티와 접촉상태를 나타낸 일부단면도로서 상술한 바와 같이 도아(1)의 고주파 차단판(2)이 캐비티(4) 내에 삽입됨으로써 밀착면을 캐비티(4)의 전면부 및 내측까지 확대하여 잔류 고주파의 누설을 방지하는 것이다.FIG. 2 is a partial cross-sectional view showing the periphery of the high frequency blocking plate and the contact state with the cavity when the door is closed. As described above, the high frequency blocking plate 2 of the door 1 is inserted into the cavity 4 to close the cavity. It extends to the front part and inside of (4), and prevents the leakage of residual high frequency.
따라서 전자렌지도아(1)가 저면부에만 밀착되는 종래의 경우에는 도아의 자중에 의하여 도아내에 연결된 안전스위치의 조정이 어려운 점이 있었으나 본 고안은 도아(!)의 고주파차단판(2)이 캐비티(4)내에 일부 삽입되어 도아(1)를 지지하기 때문에 구조적으로 도아의 안전스위치 조정이 쉽고 확실하게 할 수 있는 것이다.Therefore, in the conventional case in which the microwave oven 1 is in close contact with only the bottom part, it is difficult to adjust the safety switch connected to the door by the weight of the door, but the present invention has a cavity (!) Of the high frequency blocking plate 2 of the door (!). 4) It is partly inserted into the door 1 to support the door 1 so that the safety switch of the door can be easily and reliably adjusted.
이와 같은 본 고안에 의하면 도아(1)내의 철구조물인 고주파차단판(2)을 전자렌지 캐비티(4)내부에 삽입가능하도록 ""According to the present invention as described above, the high-frequency shielding plate 2, which is the steel structure in the door 1, may be inserted into the microwave cavity 4. "
