Description

초고주파 및 열겸용 전자렌지의 오동작 방지장치Malfunction prevention device for microwave and heat microwave

제1도는 본 고안 장치의 회로도.1 is a circuit diagram of the device of the present invention.

제2도는 제1도 장치의 작동 설명을 위한 도표.2 is a diagram for explaining the operation of the device of FIG.

본 고안은 초고주파 장치 및 가열장치를 겸용하는 전자렌지에 있어서 초고주파 장치와 가열장치가 동시에 작동되는 오동작을 방지하기 위한 장치에 관한 것이다.The present invention relates to a device for preventing a malfunction in which the microwave device and the heating device are operated at the same time in the microwave oven that combines the microwave device and the heating device.

종래의 겸용전자렌지에서는 제어기로 사용되는 마이크로 컴퓨터의 출력제어부가 파괴되어서 초고주파장치와 가열장치를 동시에 작동시키게 되는 경우가 있었는데 이렇게 두가지 장치가 작동시키게 되면 정격용량을 초과하며 사용된 각 부재들에 과부하가 걸리게 되어 소손될 뿐만 아니라 전자렌지가 과열되어 파괴되는 문제점이 있었다.In the conventional microwave oven, the output control part of the microcomputer used as a controller is destroyed, and thus, the microwave and heating devices are operated simultaneously. When the two devices are operated, the rated capacity is exceeded, and each member used is overloaded. There is a problem in that the microwave is overheated and destroyed as well as being burned.

따라서 본 고안은 이러한 종래의 문제점을 없애기 위하여 마이크로 컴퓨터의 출력제어부에 출력비교장치를 설치하여, 마이크로 컴퓨터의 출력제어부가 파괴되면 초고주파 장치와 가열장치가 비작동되도록 하되 출력제어부가 정상시에는 정상작동이 되도록 하는 오동작 방지장치를 제공하고자 하는 것으로서 첨부된 도면을 참조하여 설명하면 다음과 같다.Therefore, the present invention provides an output comparator in the output control unit of the microcomputer in order to eliminate such a conventional problem, and if the output control unit of the microcomputer is destroyed, the high frequency device and the heating device are deactivated, but the output control unit is normally operated. It will be described with reference to the accompanying drawings as to provide a malfunction preventing device to be as follows.

제 1도를 참조하여 본 고안의 구성을 설명하면,Referring to the configuration of the present invention with reference to Figure 1,

마이크로 컴퓨터(1)의 출력제어부(2)에서의 초고주파 장치 제어출력단(3)에 트랜지스터 (Q1,Q5)를 연결하여 트랜지스터 (Q1)는 초고주파 발생장치(4)의 전원제어를 하도록 하되 트랜지스터(Q5)로서는 가열장치(5)의 절원제어리드스위치(7) 구동트랜지스터 (Q3)를 제어하도록 하고, 출력제어부(2)에서의 가열장치 제어출력단(6)에는 트랜지스터(Q6,Q4)를 연결하여 트랜지스터 (Q6)는 초고주파 발생장치(4)의 전원 제어를 하는 리드스위치(8) 구동 트랜지스터(Q2)를 제어하도록 하고, 트랜지스터 (Q4)는 가열장치 (5)의 전원제어를 하도록 하여서된 것이다.Transistors Q 1 and Q 5 are connected to the microwave control device 3 at the output control unit 2 of the microcomputer 1 so that the transistor Q 1 controls power of the microwave generator 4. As the transistor Q 5 , the driving control lead switch 7 driving transistor Q 3 of the heating device 5 is controlled, and the transistor Q 6 , in the heating device control output terminal 6 of the output control unit 2 is controlled. Q 4 ) is connected so that the transistor Q 6 controls the driving switch Q 2 of the reed switch 8 which controls the power supply of the ultra-high frequency generator 4, and the transistor Q 4 is the heating device 5. This is to control the power supply.

이러한 구성의 제 2도를 참조하여 작용 효과를 설명하면 다음과 같다.Referring to Figure 2 of this configuration will be described the operation and effect.

마이크로 컴퓨터의 출련 제어부가 파괴되어 그 출력(3,6)이 모두 하이레벨로 되면 출력(3)은 저항(R1)을 통해 트랜지스터(Q1)를 온시키거나 저항(R7)을 통해 트랜지스터(Q5)는 오프되고 따라서 저항(R3,R4)을 통해 트랜지스터(Q3)도 오프된다.If the output control of the microcomputer is destroyed and its outputs 3 and 6 are all at a high level, the output 3 turns on the transistor Q 1 through the resistor R 1 or through the resistor R 7 . Q 5 is turned off and thus transistor Q 3 is turned off via resistors R 3 and R 4 .

트랜지스터 (Q3)가 오프되면 트랜지스터(Q4)가 온되어 있다해도 리드스위치 (7)는 오프되며 따라서 가열장치(5)를 구동하는 트라이악(B)는 오프되어 가열장치(5)는 구동되지 알게 된다.When the transistor Q 3 is turned off, the reed switch 7 is turned off even when the transistor Q 4 is turned on. Thus, the triac B driving the heating device 5 is turned off, and the heating device 5 is driven. I will not know.

또한 출력(3)은 저항(R8)을 통해 트랜지스터(Q6)를 오프시키므로 트랜지스터 (Q2)의 베이스 전압은 0레일로 되며 따라서 출력(3)으로 인해 트랜지스터(Q1)가 온되어 있다 하더라도 리드스위치(8)는 온될 수가 없다. 따라서 트라이악(A)은 오프되어 초고주파장치(4)를 구동시키지 않는다(제2도의 4경우임).In addition, since the output 3 turns off the transistor Q 6 through the resistor R 8 , the base voltage of the transistor Q 2 becomes zero rail and thus the transistor Q 1 is turned on due to the output 3. Even if the reed switch 8 cannot be turned on. Therefore, the triac A is turned off so as not to drive the ultra-high frequency apparatus 4 (four cases in FIG. 2).

정상 상태에서 출력(3)이 하이레벨이고 출력(6)이 로우레벨이 되면 출력(6)의 로우레벨로 인해 트랜지스터(Q6)가 온되며, 출력(3)의 하이레벨 신호에 의해 트랜지스터(Q1)도 온되며, 트랜지스터(Q6)가 온되므로 트랜지스터(Q2)도 온되어 따라서 리드스위치(8)가 온되어 트라이악(A)에 정상적인 신호를 공급하여 고주파 장치(4)를 동작시킨다.In the steady state, when the output 3 is high level and the output 6 becomes low level, the transistor Q 6 is turned on due to the low level of the output 6, and the transistor ( Q 1 ) is also turned on, and transistor Q 6 is turned on, so transistor Q 2 is turned on so that reed switch 8 is turned on to supply a normal signal to triac A to operate the high frequency device 4. Let's do it.

정상 상태에서 출력(3)이 로우 레벨이고 출력(6)이 하이레벨이 되면 출력(3)의 로우레벨로 인해 트랜지스터(Q5)가 온되며 이로 인해 트랜지스터(Q3)가 온된다.In the normal state, when the output 3 is at the low level and the output 6 is at the high level, the transistor Q 5 is turned on due to the low level of the output 3, thereby turning on the transistor Q 3 .

또한 출력(6)의 하이레벨로 인해 트랜지스터(Q4)가 온되어 리드스위치(7)가 온되어 트라이악(B)이 온되고 따라서 가열장치(5)에 전원을 공급하게 된다.In addition, the high level of the output 6 causes the transistor Q 4 to be turned on so that the reed switch 7 is turned on so that the triac B is turned on to supply power to the heating device 5.

이상에서 설명된 바와같이 본 고안에 의하면, 초고주파 장치와 가열장치가 동시에 작동될 염려가 전혀없으므로 오작동에 의한 전자렌지의 손상 내지 파괴를 완전하게 예방할 수가 있는 것이다.As described above, according to the present invention, since there is no fear that the ultra-high frequency device and the heating device are operated at the same time, it is possible to completely prevent damage or destruction of the microwave oven due to malfunction.
