본 고안은 전자렌지에 설치된 고주파 가열장치의 안전스위치를 구동시키기 위한 전자렌지의 안전스위치 구동장치에 관한 것이다.The present invention relates to a safety switch driving apparatus of a microwave oven for driving a safety switch of a high frequency heating apparatus installed in a microwave oven.

종래의 안전스위치는 전자렌지의 조리실 도어에 설치된 키이로 안전스위치의 유동자를 직접 구동시키거나 레버를 통해 간접적으로 구동시키는 구조가 사용되어 왔으나 이는 도어에 설치된 키이와 레버의 제조시에 발생되는 공차와 조평의 미숙으로 인하여 키이 또는 레버가 안전스위치의 유동자만을 구동시키지 못하고 안전스위치의 몸체의 직접 접촉하게 됨으로서 도어를 열고 닫을때 반복되는 충격력에 의하여 안전스위치자체가 파괴되거나 안전거리(0.8㎜)의 유지가 지켜지지 못하여 안전스위치의 수명이 단축되는 결점이 있었다.Conventional safety switch is a key installed in the cooking chamber door of the microwave oven has been used to direct the flow of the safety switch or indirectly through the lever has been used, but this is the tolerance that occurs during the manufacturing of the key and the lever installed in the door Due to immaturity, the key or lever does not drive the sole of the safety switch but directly contacts the body of the safety switch, so the safety switch itself is destroyed by the repeated impact force when opening or closing the door. There was a defect that the life of safety switch was shortened because maintenance was not observed.

본 고안은 이와같은 점을 감안하여 누름판과 절곡편이 구성된 회동대를 안전스위치가 설치된 고정판에 축착하여 도어의 키이가 회동대를 누를때 누름판이 안전스위치의 유동자를 간접적으로 누르도록 함으로서 안전스위치의 파손과 수명의 단축을 방지하기 위한 전자레인지의 안전스위치 구동장치를 제공하기 위한 것으로 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.In view of the above, the present invention is designed to press the rotating plate composed of the pressing plate and the bending piece to the fixed plate on which the safety switch is installed so that the pressing plate indirectly presses the actuator of the safety switch when the key of the door presses the rotating plate. In order to provide a safety switch driving apparatus of a microwave oven to prevent the shortening of the life and it will be described in detail by the accompanying drawings as follows.

제1도와 같이 구동수단(10)를 이루는 본 고안의 회동대(11)는 상단에 통공(15)을 형성시키고 하단에 힌지부(12)를 형성시켜 절곡편(13)이 탄성절곡되도록 구성하며 통공(15)과 힌지부(12)의 사이에는 안전스위치(6)의 유동자(7)를 동작시키는 누름판(14)을 형성시킨후 구동수단(10)의 회동대(11)를 고정판(1)에 형성된 스토퍼(3)와 지지대(4)사이로 삽입하면서 통공(15)을 고정축 (2)에 축착하여서 된 것이다.The rotating table 11 of the present invention constituting the driving means 10 as shown in FIG. 1 is formed so that the bending piece 13 is elastically bent by forming a through hole 15 at the upper end and a hinge portion 12 at the lower end. Between the through-hole 15 and the hinge portion 12 is formed a pressing plate 14 for operating the actuator 7 of the safety switch 6, and then the pivoting plate 11 of the drive means 10 is fixed to the fixed plate (1). The through hole 15 is affixed to the fixed shaft 2 while being inserted between the stopper 3 and the support 4 formed in the).

이와같이 구성된 본 고안은 전자렌지의 도어(16)에 설치된 키이(17)가 고정판(1)내로 삽입되어 회동대(11)를 누르면 구동수단(10)의 회동대(11)가 고정축(2)을 중심으로 회동하면서 안전스위치(6)의 유동자(7)를 동작시키는 것이로 제2도에서와 같이 구동수단(10)의 회동대(11)가 고정판(1)의 스토퍼(3)와 지지대(4)사이에 삽입되고 회동대(11)의 통공(15)이 고정축 (2)에 축착된 상태에서는 힌지부(12)에 의해 탄성력을 갖는 절곡편(13)은 지지대(4)에 탄지 됨과 동시에 누름판(14)은 안전스위치(6)의 유동자(7)에 접촉된 상태가 되는 것이다.According to the present invention, the key 17 installed in the door 16 of the microwave oven is inserted into the fixing plate 1, and the pivoting plate 11 of the driving means 10 is pressed by the pivoting shaft 11. By operating the actuator 7 of the safety switch 6 while rotating about the center, as shown in FIG. 2, the pivot 11 of the drive means 10 is provided with the stopper 3 and the support of the fixed plate 1. In the state where the through hole 15 of the pivot table 11 is inserted into the fixed shaft 2 and is inserted between (4), the bending piece 13 having elastic force by the hinge portion 12 is supported by the support 4. At the same time the pressing plate 14 is in contact with the fluid 7 of the safety switch (6).

이때 제3도와 같이 전자렌지의 도어(16)를 닫으면 도어(16)에 설치된 키이(17)가 고정판(1)내로 삽입되어 도어(17)를 록크 시킴과 동시에 구동수단(10)의 회동대(11)를 밀게 되므로 회동대(11)는 통공(15)이 삽입된 고정축(2)를 중심으로 회동하면 누름판(14)으로 안전스위치(6)의 유동자(7)를 동작시켜 안전스위치(6)을 「온」시키는 것이다.At this time, as shown in FIG. 3, when the door 16 of the microwave oven is closed, the key 17 installed in the door 16 is inserted into the fixing plate 1 to lock the door 17 and at the same time rotate the pivot table of the driving means 10 ( 11) Since the pivot 11 rotates about the fixed shaft 2 into which the through hole 15 is inserted, the pressure plate 14 operates the actuator 7 of the safety switch 6 to operate the safety switch. 6) "on".

즉 도어(16)에 설치된 키이(17)에 의해 구동수단(10)의 회동대(11)가 회동되면 고정판(1)의 지지대(4)에 탄지되어 있는 절곡편(13)은 힌지부(12)에 의해 탄성절곡 됨과동시에 회동대(11)에 일체로 형성된 누름판(14)이 안전스위치(6)의 유동자(7)를 동작시켜 안전스위치(6)를 「온」시키는 것이며 회동대(11)의 회동각도는 지지대(4)에 탄지되어 있는 절곡편(13)의 탄성력에 의해 일정한 각도로 제어되므로 안전스위치(6)의 유동자(7)를 누르면 회동대(11)의 누름판(14)은 유동자(7)를 일정한 깊이로 누르게 되는 것이다.That is, when the pivot 11 of the drive means 10 is rotated by the key 17 installed in the door 16, the bending piece 13 supported by the support 4 of the fixing plate 1 is hinged 12. The pressing plate 14 formed integrally with the rotating table 11 at the same time as the elastic bending is performed to operate the actuator 7 of the safety switch 6 to turn the safety switch 6 on. Rotation angle of the control panel is controlled at a constant angle by the elastic force of the bending piece 13 supported by the support 4 so that the pressing plate 14 of the rotation table 11 is pressed when the actuator 7 of the safety switch 6 is pressed. Is to press the fluid (7) to a constant depth.

한편 전자렌지의 도어(16)를 열어 키이(17)가 고정판(1)으로부터 이탈되면 회동대(11)를 누르는 힘이 제거되므로 구동수단(10)의 회동대(11)는 제2도와 같이 회동복귀되어 안전스위치(6)을 「오프」시키게 되는 것이다.On the other hand, when the door 17 of the microwave oven is opened and the key 17 is separated from the fixing plate 1, the force for pressing the pivot table 11 is removed, so that the pivot table 11 of the driving means 10 rotates as shown in FIG. It returns and the safety switch 6 is "off".

즉 구동수단(10)의 회동대(11)를 누르는 힘이 제거되면 회동대(11)의 힌지부(12)와 고정판(1)의 지지대(4)에 의해 탄성절곡 되었던 절곡편(13)이 회동대(11)에 복귀력을 전달하게되므로 구동수단 (10)의 회동대(11)는 통공(15)이 삽입된 고정축(2)을 중심으로회동복귀 함과 동시에 회동대(11)에 일체로 형성된 누름판(14)로 복귀되므로 누름판(14)이 안전스위치(6)의 유동자(7)로부터 이탈되어 안전스위치(6)를 「오프」시키는 것이며 절곡편(13)의 탄성력에 의해 회동복귀하는 구동수단(10)의 회동대는 고정판(1)에 형성된 스토퍼(3)에 의해 회동정지 되는 것이다.That is, when the force for pressing the pivot 11 of the drive means 10 is removed, the bending piece 13 that has been elastically bent by the hinge portion 12 of the pivot 11 and the support 4 of the fixing plate 1 is removed. Since the return force is transmitted to the pivot table 11, the pivot table 11 of the driving means 10 pivots back around the fixed shaft 2 into which the through hole 15 is inserted and simultaneously pivots on the pivot table 11. Since the return plate 14 is integrally formed, the presser plate 14 is separated from the actuator 7 of the safety switch 6 to turn off the safety switch 6 and is rotated by the elastic force of the bending piece 13. The rotating table of the return means 10 is pivotally stopped by the stopper 3 formed on the fixed plate 1.

상기에서와 같이 본 고안은 안전스위치의 유동자를 동작시키는 누름판과 힌지부에 의해 탁성력을 갖는 절곡편을 회동대에 형성시키고 회동대의 통공을 안전스위치가 설치된 고정판의 고정축에 축착시켜 구동수단을 구성시킴으로서 일체로 형성된 회동대로 안전스위치를 「온」, 「오프」시킬수 있을뿐만 아니라 다수의 부품을 조립하여 안전스위치를 「온」, 「오프」시킴에 따른 원가상승과 안전스위치의 파괴 즉 방지할수 있는 것이며 고정판의 지지대에 탄지된 절곡편에 의해 회동대의 회동이 일정하게 제어되어 누름판은 유동자를 일정한 깊이로 누르게 되므로 안전스위치의 수명 단축을 방지할수 있는 효과가 제공되는 것이다.As described above, the present invention forms a bent piece having a turbulent force by the pressing plate and the hinge portion for operating the actuator of the safety switch on the rotating table, and the opening of the rotating table is fixed to the fixed shaft of the fixed plate on which the safety switch is installed. By constructing, not only can the safety switch be turned “on” or “off” in an integrally formed rotation, but also a plurality of parts can be assembled to prevent the cost increase and the destruction of the safety switch, that is, the safety switch “on” or “off”. The rotation of the pivoting table is constantly controlled by the bending piece supported on the support plate of the fixed plate, so that the pressing plate presses the actuator to a certain depth, thereby preventing the life of the safety switch from being shortened.
