[기술분야][Technical Field]

본 고안은 전자렌지에 있어 전체가 보다 견고하도록 하는 동시에 전파누설이 방지되도록 하는 전자렌지의 캐비티 보강구조에 관한 것이다.The present invention relates to a cavity reinforcing structure of the microwave oven to make the whole more robust and to prevent radio leakage.

[고안의 배경][Design background]

일반적으로 전자렌지는 전, 후, 상, 하면판이 용접되어 조리실이 되는 내부공간, 즉 캐비티(CAVITY)가 형성되는데 종전에 있어서는 제5도에 도시된 바와 같이 단순한 면판상태로 되고 당도가 약한 전, 후, 상, 하면판(a∼d)이 용접되는 구조로 이루어져 있기 때문에 쉽게 휘어지는 변형이 발생되므로서 전면판(a)의 경우 도어와의 틈이 생김에 따라 전파누설이 많이 되는 문제점이 초래되었을 뿐만 아니라 도어와 접촉되면서 소음이 크게 발생되는 현상이 야기되는 문제점이 있었다.In general, the microwave oven is formed before, after, the upper and lower plates are welded to form an inner space, that is, a cavity (CAVITY). In the past, as shown in FIG. Afterwards, since the upper and lower plates a to d are welded, deformations are easily bent, and in the case of the front plate a, a large amount of radio leakage occurs due to a gap with the door. In addition, there was a problem that a phenomenon that the noise is greatly generated while contacting the door.

[고안의 목적][Purpose of designation]

본 고안은 상기한 바와 같은 종래의 제반 문제점을 감안하여 캐비티를 형성하는 구조가 보다 보강되도록 하므로서 전파누설을 방지하고 소음경감을 도모하려는데 그 목적이 있는 것이다.The present invention aims to prevent radio leakage and to reduce noise by improving the structure of the cavity in view of the conventional problems as described above.

[고안의 요약]Summary of the proposal

상기한 목적을 달성하기 위해 본 고안은 전, 후면판에 보강요부를 가지도록 하는 한편 전면판의 보강요부에는 도어에 설치되는 옵서버의 삽입돌부가 도어폐문이 되도록 안출되어 있다.In order to achieve the above object, the present invention has a reinforcing recess on the front and rear plates, while the reinforcing recesses of the front plate are designed so that the insertion protrusion of the observer installed in the door becomes the door closing door.

[고안의 구체적 실시예에 대한 설명][Description of Specific Example of Design]

이하, 본 고안을 첨부도면을 참조하여 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 저면판(1)의 개구부(1a) 외주변에 테두리형의 보강요부(5)가 형성되도록 하는 한편 후면판(2)에 호 상, 하부에 보강요부(5')가 형성되도록 한다.The present invention allows the frame-shaped reinforcing recesses 5 to be formed on the outer periphery of the opening 1a of the bottom plate 1, while the reinforcing recesses 5 'are formed on the lower and upper sides of the back plate 2, respectively. .

상기 보강요부(5)(5')는 전, 후면판(1)(2)의 절곡작업시 형성되는 것으로서 동일한 높이를 가지도록 절곡형성된다.The reinforcing recesses 5 and 5 'are formed at the front and rear plates 1 and 2, and are bent to have the same height.

그리고 상, 하판(3)(4)이 보강요부(5)(5')의 안쪽부분에 각각 용접되어 캐비티(6)를 이루도록 구성되는 한편 도어(7)에 부착되어 전파흡수기능을 하는 업서버(8)에는 삽입돌부(9)가 형성되도록 구성한다.The upper and lower plates 3 and 4 are welded to the inner portions of the reinforcing recesses 5 and 5 ', respectively, to form a cavity 6, and attached to the door 7 to absorb radio waves. (8) is configured such that the insertion protrusion 9 is formed.

도면중 미설명부호 10은 도어스크린이고 W는 용접부위를 나타낸 것이다.In the figure, reference numeral 10 denotes a door screen and W denotes a welded portion.

이와 같이 구성된 본 고안은 전면판(1)과 후면판(2)에 각각의 보강요부(5)(5')가 절곡형성되어 있기 때문에 판자체적으로 견고성이 보강되게 된다.In the present invention configured as described above, since the reinforcing recesses 5 and 5 ′ are bent on the front plate 1 and the rear plate 2, the rigidity of the board is reinforced.

또한, 본 고안은 보강요부(5)(5') 내측으로 상, 하판(3)(4)이 용접되기 때문에 즉, 다른 부위보다는 더욱 강한 견지력을 가지는 보강요부(5)(5') 부근에 상, 하판(3)(4)이 용접되므로 전체적으로 볼 때 보다 안정적이고 보강력을 가지는 구조가 되는 것이다.In addition, since the upper and lower plates 3 and 4 are welded to the inner side of the reinforcing recess 5, 5 ′, that is, the vicinity of the reinforcing recess 5, 5 ′ having a stronger holding force than other parts. In the upper and lower plates (3) (4) is welded to be a more stable and reinforcing structure as a whole.

그리고 본 고안은 전면판(1)의 보강력을 가지기 위하여 형성되는 보강요부(5)에 도어(7) 업서버(8)의 삽입돌부(9)가 삽입 폐문되고 이탈 개문되도록 함에 따라 전파누설을 방지함과 동시에 도어(7)의 폐문작동시 보강요부(5)에 삽입돌부(9)가 끼워 들어가는 접촉이 먼저 이루어지기 때문에 소음발생이 보다 완화되게 된다.In addition, the present invention allows the insertion protrusion 9 of the door 7 and the upserver 8 to the reinforcing recess 5 formed to have the reinforcing force of the front plate 1 so that the insertion protrusion 9 of the door 7 and the upserver 8 is closed and separated. At the same time to prevent the noise from the noise generated is further reduced because the first contact is made to insert the protrusion 9 into the reinforcing recess (5) during the closing operation of the door (7).

이상에서와 같이 본 고안은 강도가 약한 전, 후면판(1)(2)이 보강요부(5)(5')에 의해 보다 보강되므로 휘어짐변형이 방지되게 되고 보강요부(5)에 삽입돌부(9)가 삽입 폐문되므로서 도어(7)가 닫힐 때 나는 소음이 보다 경감될 뿐 아니라 전파누설을 미연에 방지할 수 있게 되는 효과를 제공하게 되는 것이다.As described above, the present invention is because the front, back plate (1) (2) of the strength is more reinforced by the reinforcing recess (5) (5 ') is prevented from deformation and the insertion protrusion (reinforcement recess 5) As the 9 is inserted and closed, the noise generated when the door 7 is closed is further reduced, and the radio leakage can be prevented in advance.
