본 고안은 오븐램프(Oven Lamp)에 관한 것으로, 특히 전압절환에 관계없이 단일 오븐램프를 사용하도록한 전원절환표시 오븐램프회로에 관한것이다.The present invention relates to an oven lamp, and more particularly, to a power switching display oven lamp circuit using a single oven lamp regardless of voltage switching.

종래의 기술구성은 제1도에서 보는바와같이 100V전원을 인가했을 경우에 100V선택콘넥터(C5)의 단자(1')에 공통콘넥터(C3)의 단자(1)가 연결되면 1차안전스위치(PS)를 통해 오븐램프(OL1)가 작동하게 되어 있다. 또한 공통콘넥터(C3)의 단자(4)와 (5)가 각각 100V선택콘넥터(C5)의 단자(4')와 (5')를 통하여 오븐램브(OL2)가 작동하게 된다.The prior art configuration is the first safety if the terminal 1 of the common connector C 3 is connected to the terminal 1 'of the 100V selection connector C 5 when 100V power is applied as shown in FIG. The oven lamp OL 1 is activated by the switch PS. In addition, the oven lamps OL 2 operate through the terminals 4 'and 5' of the common connector C 3 through the terminals 4 'and 5' of the 100V select connector C 5 , respectively.

즉, 100V교류(AC)전원은 100V용 휴즈(f2), 100V선택 콘넥터(C5)의 단자(1'), 공통콘넥터(C3)의 단자(1), 1차 안전스위치(PS), 오븐램프(OL1), 공통콘넥터(C3)의 단자(4), 100V선택콘넥터(C5)의 단자(4')를 통해 전류가 흘러 오븐램프(OL1)가 점등되고, 1차안전스위치(PS)에서 공통콘넥터(C3)의 단자(5), 100V선택콘넥터(C5)의 단자(5'), 오븐램프(OL2)를 통해 전류가 흘러 오븐램프(OL1)가 점등된다.That is, the 100V AC power supply is a fuse for the 100V (f 2 ), a terminal 1 'of the 100V selection connector (C 5 ), a terminal (1) of the common connector (C 3 ), and a primary safety switch (PS). Oven lamp (OL 1 ) is turned on, the oven lamp (OL 1 ) is turned on, and current flows through terminal (4) of common lamp (OL 1 ), common connector (C 3 ), and terminal 4 'of 100V selection connector (C 5 ). In the safety switch PS, current flows through the terminal 5 of the common connector C 3 , the terminal 5 ′ of the 100 V selection connector C 5 , and the oven lamp OL 2 so that the oven lamp OL 1 Lights up.

또한 220V 전원을 인가 했을 경우에는 공통콘넥터(C3)의 단자(1∼4)를 220V 선택콘넥터(C4)의 단자(1"∼4")에 연결하면 200V 교류전원은 220V용 퓨즈(f1), 220V 선택콘넥터(C4)의 단자(1"), 공통콘넥터(C3)의 단자(1), 1차 안전스위치(PS)를 통해 오븐램프(OL1)에 인가되어 오븐램프(OL1)만 점등되고, 오븐램프(OL2)는 전압 O〔V〕로서 점등되지 않게된다.In addition, when 220V power is applied, if the terminals 1 to 4 of the common connector C 3 are connected to the terminals 1 "to 4" of the 220V select connector C 4 , the 200V AC power supply uses a 220V fuse (f). 1 ), the oven lamp (OL 1 ) is applied to the oven lamp (OL 1 ) through the terminal 1 "of the 220V selection connector (C 4 ), the terminal (1) of the common connector (C 3 ), and the primary safety switch (PS). Only OL 1 ) is turned on and the oven lamp OL 2 is not turned on as the voltage O [V].

따라서 오븐램프(OL1)는 220V용으로, 오븐램프(OL2)는 100V로서 상호 전원 연결에 따라 선택되어졌다.Therefore, oven lamp OL1 is selected for 220V and oven lamp OL2 is 100V, which is selected according to mutual power connection.

그러나 이와같은 종래의 기술구성에 있어서는 전원절환에 따라서 오븐램프를 2개사용하며, 전원절환유용성에 맞도록하기 위해 6핀(Pin)콘넥터를 사용하여, 가격이 상승함은 물론, 생산성이 저하되는 단점이 있었다. 이에따라 상기한 단점을 해결한 본 고안의 기술구성을 첨부된 도면에 따라 설명하면 다음과 같다.However, in such a conventional technology configuration, two oven lamps are used according to power switching, and a 6-pin connector is used to meet the power switching utility, thereby increasing the price and decreasing productivity. There was a downside. Accordingly, the technical configuration of the present invention that solves the above disadvantages will be described according to the accompanying drawings.

제2도에서 100V전원선택시 100V 교류전원은 100V용 퓨즈(f2), 100V선택콘넥터(C5)의 단자(1'), 공통콘넥터(C3)의 단자(1), 타이머스위치(TS)의 공통단자, 오븐램프(OL1), 공통콘넥터(C3)의 단자(4)를 통해 전류가 흘러 오븐램프(OL1)는 점등되며, 220V 전원선택시 220V 교류전원은 220V용 퓨즈(f1), 220V 선택콘넥터(C4)의 단자(2")를 통해 고압트랜스(VT)에 인가되고, 상기 고압트랜스(VT)에서 전압강하가 생겨 100V로 하향 조정되어 220V 선택콘넥터(C4)의 단자(1"), 공통콘넥터(C3)의 단자(1), 타이머스위치(TS)의 공통단자, 오븐램프(OL1), 공통콘넥터(C3)의 단자(4)를 통해 전류가 흘러 오븐램프(OL1)가 점등된다. 또한 공통콘넥터(C3)에 설치된 전압안전 스위치(SVS)는 전원전압의 선택에 따라서 안전스위치 역할을 하게되고, 인터락(Interlock)회로구성은 프라이머리스위치(PS), 모니터스위치(MS)를 통해 형성된다.In FIG. 2, when the 100V power is selected, the 100V AC power supply includes the fuse for the 100V (f 2 ), the terminal (1 ') of the 100V selection connector (C 5 ), the terminal (1) of the common connector (C 3 ), and the timer switch (TS). ) The current flows through the common terminal of the common terminal, oven lamp (OL 1 ) and terminal (4) of the common connector (C 3 ), and the oven lamp (OL 1 ) is turned on. f 1 ), and applied to the high voltage transformer (VT) through the terminal (2 ") of the 220V select connector (C 4 ), a voltage drop is generated in the high voltage transformer (VT) to be adjusted down to 100V to 220V select connector (C 4) Current through terminal 1 "), terminal 1 of common connector C 3 , common terminal of timer switch TS, oven lamp OL 1 , and terminal 4 of common connector C 3 . The oven lamp OL 1 lights up. In addition, the voltage safety switch (SVS) installed in the common connector (C 3 ) acts as a safety switch according to the selection of the power supply voltage, and the interlock circuit configuration uses the primary switch (PS) and the monitor switch (MS). Is formed through.

이와같이 본 고안에 따른 전원절환표시 오븐램프회로는 오븐램프를 1개사용하여 전원절환 선택에 관계없이 동작하도록하고, 4핀 콘넥터를 사용하여 원가가 절감됨은 물론 생산성이 향상되는 효과를 갖게된다.As described above, the power switching display oven lamp circuit according to the present invention uses one oven lamp to operate regardless of the power switching selection, and the cost is reduced as well as productivity is increased by using a 4-pin connector.
