20은 하부이젝트레버로서, 축(21)을 중심으로 회동되도록 설치되어 있으며 그 상단에는 걸림편(22)과 누름돌기(23)가 형성되고 하단에는 이젝트버튼(미도시)에 의해 조작되도록 캠홀(24)이 마련되어 있다.20 is a lower eject lever, which is installed to rotate around the shaft 21, and a locking piece 22 and a pressing protrusion 23 are formed at an upper end thereof, and a cam hole (not shown) to be operated by an eject button (not shown). 24) is provided.
30은 도어(60)의 누름봉(62)에 의해 승강작동하는 작동구로서, 누름봉(63)의 누름을 받는 경사면(31)이 전면에 형성되고 하부에 탄발스프링(32)이 설치되어 있다. 이 작동구(30)는 상기 모니터스위치(S3)와 제2안전스위치(S2)사이에서 승강되도록 설치된다.30 is an operation tool for lifting and lowering by the push rod 62 of the door 60. An inclined surface 31 which is pushed by the push rod 63 is formed on the front side, and a tan ball spring 32 is provided at the bottom thereof. . This operating port 30 is installed to be elevated between the monitor switch (S3) and the second safety switch (S2).
40은 상기 기판(10)과 별개로 구성된 상부후크홀더로서, 상부후크(61)의 걸림턱(41)의 하부에 후방으로 향하는 협지편(42)이 형성되어 있다.40 is an upper hook holder configured separately from the substrate 10, and a clamping piece 42 facing backward is formed at a lower portion of the locking jaw 41 of the upper hook 61.
50은 상부이젝트레버로서, 하단에 요홈(51)이 형성되어 하부이젝트레버(20)의 상단과 결합되고 상단은 상부 후크홀더(40)의 걸림턱(41) 하방에 위치하도록 협지편(42)에 협지되어 있다.50 is an upper eject lever, the groove 51 is formed at the lower end is coupled to the upper end of the lower eject lever 20, the upper end of the clamping piece 42 to be located below the locking jaw 41 of the upper hook holder 40 It is narrowed in
상기와 같이 구성된 본 고안은 제1도, 제2도 및 제3a도와 같이 도어(60)가 열린상태에서는 상부이젝트레버(50), 하부이젝트레버(20), 작동구(30)가 상승된 위치에 있게되어 모니터스위치(S3), 제1안전스위치(S1), 제2안전스위치(S2), 스타트스위치(S4)등 모든 스위치가 대기상태에 있다가, 도어(60)가 닫혀지면, 도어의 상, 하부후크(61)(62)가 상, 하후크홀더(40)(11)의 걸림턱(41)(11a)에 걸림과 동시에 상, 하부이젝트레버(50)(20)를 눌러주게됨과 동시에 누름봉(63)이 경사면(31)을 타고 들어 가면서 작동구(30)를 하강시키 모니터스위치(S3), 제1안전스위치(S1), 제2안전스위치(S2)를 ON시켜주는 한편, 스타트스위치(S4)는 대기상태에 돌입하게 된다.The present invention configured as described above, the upper ejection lever 50, the lower ejection lever 20, the operation opening 30 is raised in the state in which the door 60 is opened as shown in FIGS. 1, 2 and 3a When all the switches such as the monitor switch (S3), the first safety switch (S1), the second safety switch (S2), the start switch (S4) are in the standby state, and the door 60 is closed, The upper and lower hooks 61 and 62 are engaged with the locking jaws 41 and 11a of the upper and lower hook holders 40 and 11 and simultaneously press the upper and lower eject levers 50 and 20. At the same time, the push rod 63 enters the inclined surface 31 and lowers the operation port 30 to turn on the monitor switch S3, the first safety switch S1, and the second safety switch S2. The start switch S4 enters the standby state.
이러한 상태에서 사용자가 스타트버튼(미도시)을 눌러주면 대기중이던 스타트스위치(S4)가 ON되어 결국 전자레인지는 가열작동을 하게된다.In this state, when the user presses a start button (not shown), the standby start switch S4 is turned on and eventually the microwave oven is heated.
상기와 같이 작동 하다가 세팅된 조리시간이 다되면 모든 작동은 중앙 제어시스템에 의해 자동 정지되고, 이때 사용자가 이젝트버튼(미도시)을 누르면 제2도에 도시된 하부이젝트레버(20)가 축(21)을 중심으로 하여 반시계방향으로 회전하면서 그 상단이 상승하게 되면서 하부후크(62)를 밀어올림과 동시에 상부이젝트레버(50)도 상승하면서 상부후크(61)를 밀어올려 도어(60)를 열어주게 된다.As described above, when the set cooking time is reached, all operations are automatically stopped by the central control system. When the user presses an eject button (not shown), the lower eject lever 20 shown in FIG. 21, while rotating in a counterclockwise direction, the upper portion of the upper hook is raised, while the upper hook lever 50 is raised, the upper hook 61 is pushed up, and the upper hook 61 is pushed up to open the door 60. Open it.
이상과 같이 작동하는 본 고안은 모든 스위치동작이 체계적으로 ON, OFF됨과 동시에 도어의 상, 하부후크 및 누름봉과 연계동작을 하면서 모든 스위치를 동작시켜주는 수단들이 정확하게 작동하고 열변형등이 일어날 염려가 없어 제품의 안전성을 향상시키고 구성이 간단하게 제작 및 조립을 간편하게 하는 것등의 특징을 지는 것이다.This design works as described above, all the switch operation is systematically ON, OFF and at the same time the means to operate all the switches while operating in conjunction with the upper, lower hooks and push rods of the door, there is a risk of heat deformation, etc. It improves the safety of the product and makes it easy to manufacture and assemble.
