본 고안은 전자렌지에 있어서 PCB(인쇄회로기판)설치구조의 개선에 관한 것으로, 특히 조리실상부에 전열 히터를 설치운용하는 타입의 전자렌지에 유리하게 적용될 수 있도록 안출한 새롭고 유용한 PCB설치구조에 관한 것이다.The present invention relates to the improvement of the PCB (printed circuit board) installation structure in a microwave oven, and in particular, to a new and useful PCB installation structure designed to be advantageously applied to a microwave oven of a type in which an electric heating heater is installed on an upper part of a cooking chamber. will be.
종래에 이러한 타입의 전자렌지는 그 조리실상부에 설치된 전열히터로 인해 렌지가동중 조리실 상측벽부가 상당한 고열상태로 가열되기 때문에 이 조리실 상측벽부와 캐비넷 상판사이의 공간내에 PCB를 설치하는 것이 유리한 경우(예컨대 렌지의 콘트롤부가 렌지의 전면상부에 위치하는 등의 경우)에 있어서도 PCB를 그와 같이 설치하지 못하고 상기 조리실 상측벽부로부터 멀리 떨어진 위치(주로 여러가지 부품들이 복잡하게 설치되는 전장부내)에 설치해주어야 함으로써 렌지의 설계제작상에 많은 제한과 어러움을 초래하였을 뿐만 아니라 PCB와 콘트롤부사이의 거리가 멀어져 그 연결전선들의 길이가 현저히 길어지는 관계로 전선들의 연결 및 그 처리 정리에 많은 번거로움과 경비소요가 뒤따르는 것등의 문제점이 있었다.Conventionally, this type of microwave oven is advantageous to install a PCB in the space between the upper wall of the chamber and the cabinet top plate because the upper wall of the cooking chamber is heated to a considerable high temperature during the operation of the oven due to the electric heater installed in the upper part of the cooking chamber. Even in the case where the control part of the stove is located on the front of the stove, the PCB cannot be installed in such a way, and is installed at a position far away from the upper wall of the cooking chamber (mainly in the electric part where various components are complicatedly installed). In addition to the limitations and difficulties in designing the microwave oven, the distance between the PCB and the control unit is increased, and the length of the connecting wires is considerably longer. There was a problem such as a riot following.
본 고안은 이러한 전자렌지의 조리실 상측벽부직상부에 PCB를 벽부와 근접시켜 설치하는 것을 가능케 할수 있는 수단을 재공하여 상기와 같은 종래의 문제점을 효과있게 해소하고자 안출한 것으로, 그 구체적인 기술내용과 작용효과를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made to effectively solve the above-mentioned problems by providing a means for enabling the PCB to be installed in close proximity to the upper wall portion of the cooking chamber of the microwave oven. The effects will be described in detail with reference to the accompanying drawings as follows.
즉, 본 고안은 도어(2)가 설치된 전면상부에 콘트롤부(3)가 위치하고 그 조리실(4)내 상부에는 전열히터(도시되지 않음)를 설치사용하는 종류의 전자렌지(1)에 있어서, 조리실 벽부, 특히 상측벽부(5)의 외측을 단열층(6)으로 둘러싸고 이 단열층(6)외측에 보조외판(7)을 부착고정하되 상기 보조외판(7)상의 적소에 다수의 돌출 지지부(8)를 두어 이들 돌출지지부(8)상에 PCB(9)를 설치고정토록 하는 것을 특징으로 하는 것이다.That is, in the present invention, in the microwave oven 1 of the type in which the control unit 3 is disposed on the front surface where the door 2 is installed, and the heat transfer heater (not shown) is installed on the upper part of the cooking chamber 4, Surround the outer side of the cooking chamber wall, in particular the upper wall part 5, with a heat insulating layer 6, and fix the auxiliary shell 7 to the outside of the heat insulating layer 6, but with a number of projecting supports 8 in place on the auxiliary shell 7. It is characterized in that the mounting and fixing the PCB (9) on these protruding support (8).
도시된 실시예에서 상기 돌출지지부(8)들은 보조외판(7) 몸체로부터 일체로 타발형성되어 그 전후양단이 보조외판(7)에 일체로 연결되어 있고 좌우양단은 보조외판(7)으로부터 적정 거리로 떨어져 나온 그러한 형태로 형성되어 있으며, 이와같이 형성됨으로써 상기 돌출지지부(8)하면과 보조외판(7)사이에는 적정의 통기공간부(10)가 효과적으로 형성제공된다.In the illustrated embodiment, the protruding supports 8 are integrally punched from the body of the auxiliary shell 7 so that both front and rear ends thereof are integrally connected to the auxiliary shell 7 and the right and left ends are appropriate distances from the auxiliary shell 7. It is formed in such a shape as to be separated from each other, so that the appropriate aeration space 10 is effectively provided between the lower surface of the protruding support 8 and the auxiliary shell 7.
변형 실시예에 있어서는, 상기 돌출지지부(8)들이 열전도율이 보다 낮은 별도의 재질로 형성된 후 보조외판(7)상의 설정된 위치에 별도로 결합설치될 수 있다.In a variant embodiment, the protruding supports 8 may be formed of a separate material having a lower thermal conductivity and then separately installed at a predetermined position on the auxiliary outer plate 7.
PCB(9)는 위와 같은 돌출지지부(8)들상에 예컨대 스크류우(11)와 같은 통상의 고정수단을 통해 제2도의 예와 같이 설치고정될수 있으며, 이와같이 설치된 상태에서 상기 PCB(9)에는 렌지가동중 조리실 상측벽부(5)로부터의 열이 단열층(6)에 의해 차단되어 이에 거의 이르지 못하게 됨과 동시에 상기 단열층(6) 및 보조외판(7)을 통해 전해지는 약간의 여열도 상술한 돌출지지부(8)를 하방의 공간부(10)를 통한 통기작용에 의해 효과 적으로 방열되어서 결국 상기 PCB(9)는 조리실 상측벽부(5)로부터의 고열로부터 완벽히 차단 보호되어지는 것이다.The PCB 9 can be fixed on the protruding supports 8 as above by means of a conventional fixing means such as, for example, the screw 11, as in the example of FIG. The heat from the cooking chamber upper wall part 5 during operation is blocked by the heat insulating layer 6 and hardly reaches this, and at the same time, a slight amount of heat transmitted through the heat insulating layer 6 and the auxiliary outer plate 7 is also provided. (8) is effectively dissipated by aeration through the lower space portion 10 so that the PCB 9 is completely blocked and protected from the high heat from the upper wall portion 5 of the cooking chamber.
따라서 본 고안은 위와 같은 설치구조 및 그 작용효과를 통해 PCB(9)를, 콘트롤부(3)와 근접한 위치의 조리실 상측벽부(5)바로 위쪽 공간내에 아무런 제약없이 견실, 안정적으로 설치해줄수가 있으므로 이러한 전자렌지의 설계제작상에 많은 융통성과 자유도를 제공할 수 있고, 또 상기 PCB(9)와 콘트롤부(3)간의 거리 및 그 연결전선들의 길이를 최대한으로 짧게하여 렌지조립상의 간편화와 경비절감을 도모할수 있는 것등의 다대한 이점을 지닌 것이다.Therefore, the present invention can install the PCB (9) through the above-described installation structure and the effect thereof, without any restrictions in the upper space immediately above the upper wall part 5 of the cooking compartment close to the control unit 3, without any restrictions Therefore, it is possible to provide a lot of flexibility and degree of freedom in the design and manufacturing of such a microwave oven, and to simplify the cost and assembly cost of the microwave oven by shortening the distance between the PCB (9) and the control unit (3) and the length of the connecting wires to the maximum. It has many advantages, such as savings.
