종래의 전기밥솥에 있어서는 밥의 상태 즉, 밥이 질거나 된밥으로 조정하는데는 쌀에 가하는 물의 양에 따라 결정지울 수가 있으나, 전기 압력솥에 있어서는 진밥을 짓기 위하여 물을 많이 넣는 경우에 있어서나 또는 된밥을 짓기 위하여 물을 적게 붓거나 관계없이 압력솥내의 습기가 어느 정도 증발한 뒤에야 가열이 끝나도록된 것이므로 결국은 질거나 된밥이 되지 않고 찰기가 흐르는 보통의 압력솥밥이 되고 만다.In a conventional electric rice cooker, the condition of the rice, that is, the rice is cooked or adjusted, depending on the amount of water added to the rice can be determined, but in the electric pressure cooker in the case of adding a lot of water in order to make a jinbap or cooked rice Regardless of the amount of water poured into the cooker, the moisture in the pressure cooker has evaporated to some extent so that the heating is finished, so it does not become boiled or boiled rice.

Since the heater line RO is also known, specific illustrations and descriptions thereof are omitted for simplicity of the specification.

따라서 본 고안의 전기적 회로도를 설명함으로서 본 고안을 쉽게 이해될 것이다.Therefore, the present invention will be easily understood by explaining the electrical circuit diagram of the present invention.

즉 제2도에 있어서 비교증폭기(IC)의 비반전입력단(B)에는 저항(R1)을 통해 절환스위치(SW)의 가동단자(4)에 연결되어 반고정저항(R3)과 연결되는 고정단자(1)와 반고정저항(R4)과 연결되는 고정단자(2) 및 반고정저함(R14)과 연결되는 고정단자(3)를 선택적으로 절환 접속하도록 되고 상기한 반고정저항(R3, R4, R14)은 접지와 비교증폭기(IC)의 진원입력단 사이에 연결된 저항(R2)과 저항(R5)의 분압전압에 연결되었으며, 상기한 비교증폭기(IC)의 반전입력단자(A)에는 온도센서인 서미스너(Th)를 통해 접지되어 있다. 또 상기 비교증폭기(IC)의 출력단(C)은 입부가 다이오드(D1)와 저함(R8)과 저항(R9)이 직연결하여 에미터 접지된 트랜지스터(Tr1)의 베이스에 연결되고 콜렉터와 전원(B+)사이에는 릴레이(Ry1)가 접속되었으며, 또 상기한 비교증폭기(lC)의 출력단(C)일부는 다이오드(D2)와 저항(R6)및 콘덴서(C1)를 직열로 하여 접지되어 있으며, 콘덴서(C2)의 방전시의 전류를 재너다이오드(ZD3)를 통해 콜렉터가 저항(R1)을 통해 에미터 정지된 트랜지스터(Tr3)의 베이스에 연결된 트랜지스터(Tr4)의 베이스에 통전하므로서 상기 트랜지스터(Tr3)와 트랜지스터(Tr2)로 되는 스위칭회로를 통해 트랜지스터(Tr2)의 콜렉터와 전원(B+)사이에 연결되는 릴레이(Ry2)접점을 통해 보조히이터선(RO)에의 통전을 콘트롤하도록 하여서 된 것이다.That is, in FIG. 2, the non-inverting input terminal B of the comparative amplifier IC is connected to the movable terminal 4 of the switching switch SW through a resistor R 1 and connected to the semi-fixed resistor R 3 . The fixed terminal 1 and the fixed terminal 2 connected to the semi-fixed resistor R 4 and the fixed terminal 3 connected to the semi-fixed fixture R 14 are selectively switched and connected to each other. R 3 , R 4 , and R 14 ) are connected to the divided voltages of the resistor R 2 and the resistor R 5 , which are connected between the ground and the input terminal of the comparative amplifier IC, and the inverting of the comparative amplifier IC described above. The input terminal A is grounded through a thermistor (Th), which is a temperature sensor. In addition, the output terminal C of the comparison amplifier IC is connected to the base of the transistor Tr 1 having an emitter grounded by directly connecting a diode D 1 , a resistor R 8 , and a resistor R 9 . A relay Ry 1 is connected between the collector and the power supply B + , and the output terminal C of the comparative amplifier lC is a diode D 2 , a resistor R 6 , and a capacitor C 1 . Is grounded in series, and the transistor connected to the base of the transistor Tr 3 whose emitter is stopped through the resistor R 1 through the zener diode ZD 3 is used to discharge the current during the discharge of the capacitor C 2 . The relay Ry 2 contact is connected between the collector of the transistor Tr 2 and the power supply B + through a switching circuit comprising the transistors Tr 3 and Tr 2 while energizing the base of Tr 4 . This is to control the energization to the auxiliary heater line (RO) through.

도면중 미설명부호 ZD1은 저항(R7)과 함께 상기한 비교증폭기(IC)에 정전압을 공급키 위한 제너다이오드이며, ZD2는 제너다이오드, C1은 콘덴서로 저항(R8, R9)와 시정수가 결정됨을 의미한다.In the drawing, reference numeral ZD 1 denotes a zener diode for supplying a constant voltage to the comparative amplifier IC together with the resistor R 7 , ZD 2 denotes a zener diode, and C 1 denotes a resistor R 8 , R 9. ) And time constant are determined.

상기와 같은 구성으로되는 것이므로 교류입력단자 L1, L2사이에 전원을 인가하고 정원(B+)에도 직류전류를 인가하는 경우 온도센서인 서미스터(Th)에 의해 비교증폭기(IC)의 출력층에는 +가 되어 이 신호는 다이오드(D1)가 도통됨으로 그 신호는 저항(R8)을 통해 콘덴서(C1)를 층전하기 시작하고 방전개시되면 저항(R9)을 통해 에미터 접지된 트랜지스터(Tr1)의 베이스에 인가되므로 콜렉터와 전원(B+)사이에 연결된 릴레이(Ry1)가 여자된다. 따라서 릴레이(R1)접점이 주가열히이터(Rm)하게 되고, 이와같은 가열이지속되면서 온도설정 반고정저항 R3, R4, R14으로 설정된 온도가 되면 서미스터(Th)의 저항변화에 따라 비교증폭기(IC)의 반전입력단자(A)와 비반전입력단자(B) 사이에 전위차가 발생함으로 비교 증폭기(IC)의 출력은 +에서 -으로 변하므로 콘텐서(C1)에 충전되었던 전하가 저항(R9)을 통해 방전되는 시간동안 릴레이(Ry1)는 여자되었다가 멈추게됨으로 주가열히이터(Rm)에 의한 가열이 멈추게 되어, 또 상기한 비교증폭기(IC)의 출력이 -로 됨으로 인하여 이번에는 다이오드(D2)와 저항(R8)으로 콘덴서(C2)를 충전하기 시작된다. 이와같이 충전된 전하가 방전되기 시작하면 제너다이오드(ZD3)에 의해 트랜지스터 (Tr4)가 통전됨으로 전원(B+)은 저항(R10)과 트랜지스터(Tr4)의 에미터,-콜렉터가 도통되어 저항(R11)용 통해 트랜지스터(Tr3)를 턴-온시키므로 지금까지 저항(R13, R12)으로 도통상태에 있던 트랜지스터(Tr3)의 베이스전압을 바이어스시켜 트랜지스터(Tr2)는 오프되어 릴레이(Ry2)단자에 의한 보조히이터(RO)애 통전을 중지하고 또 콘덴서(C2)가 방전되어 다시 충전되는 동안 릴레이(Ry2)가 도통되는바 이와같이 콘덴서(C2)의 충전방전함에 따라 계속 온, 오프가 되풀이됨은 본 출원인의 선출된 제89-18240호에 의해 이미 제안된바 있다.In this case, when the power is applied between the AC input terminals L 1 and L 2 and the DC current is applied to the garden B + , the temperature sensor thermistor (Th) provides an output layer of the comparative amplifier (IC). This signal becomes positive and the diode (D 1 ) is conducted so that the signal begins to layer capacitor (C 1 ) through resistor (R 8 ) and when discharge is initiated, the emitter grounded through resistor (R 9 ) ( Since it is applied to the base of Tr 1 ), the relay Ry 1 connected between the collector and the power supply B + is excited. Therefore, the relay (R 1 ) contact becomes the main heating heater (Rm), and if the temperature is set to the temperature setting semi-fixed resistors R 3 , R 4 , and R 14 as the heating continues, the resistance of the thermistor (Th) changes. Since the potential difference is generated between the inverting input terminal A and the non-inverting input terminal B of the comparison amplifier IC, the output of the comparison amplifier IC changes from + to-so that the charge charged in the capacitor C 1 is increased. Since the relay Ry 1 is excited and stopped during the time that is discharged through the resistor R 9 , the heating by the main heating heater Rm is stopped, and the output of the comparative amplifier IC becomes-. This time charging of the capacitor C 2 with the diode D 2 and the resistor R 8 begins. When the charged charge starts to be discharged, the transistor Tr 4 is energized by the zener diode ZD 3 , so that the power supply B + conducts the emitter and collector of the resistor R 10 and the transistor Tr 4 . resistance (R 11) turns on the transistor (Tr 3) through for -one because so far resisted by biasing the base voltage of the transistor (Tr 3) which was in a conductive state with (R 13, R 12) a transistor (Tr 2) is off is chungjeonbang ships of the relay (Ry 2) the auxiliary heater (RO) Ke relay bar in this way capacitor (C 2) is (Ry 2) it is conductive for stopping the power application, and is also a capacitor (C 2) discharge to be charged again by terminal Repeated on and off in accordance with has already been proposed by the Applicant's elected 89-18240.

그러나 본 고안에 있어서는 비교증폭기(IC)의 비반전입력단(B)에 저함(R1)을 통해 절환스위치(SW)의 가동단자(4)에 연결된 것이므로 반고정저항(R3, R4, R14)으로 연결된 고정단자(1, 2, 3)의 어느 단자에 절환연결되느냐에 따라 반고정저항의 저항치에 의해 압력솥내의 밥이 익은 상태 즉, 질거나 보용이거나 또는 된밥을 선정할수가 있게 되는 것이다.However, in the present invention, since the non-inverting input terminal (B) of the comparative amplifier (IC) is connected to the movable terminal (4) of the switching switch (SW) through the low point (R 1 ), the semi-fixed resistors R 3 , R 4 , R 14 ) The rice in the pressure cooker is ripe, i.e., it can be cooked, boiled or picked, depending on which terminal of the fixed terminals (1, 2, 3) connected to it. .

도시에서는 가동단자(4)가 고정단자(1)에 연결되는 경우 비반전입력단자(B)와 접지사이의 저항치가 커지므로 진밥이 되고 가동단자(4)가 고정단자(3)에 연결하는 경우 저항치에 의해 된밥이며, 고정단자(2)에 연결되는 경우 보통의 찰진밥이 되도록 설정할 수가 있는 것이다.In the city, when the movable terminal 4 is connected to the fixed terminal 1, the resistance value between the non-inverting input terminal B and the ground becomes large, and thus, it becomes a jinbap and the movable terminal 4 is connected to the fixed terminal 3. By the resistance value, the rice is, when connected to the fixed terminal (2) can be set to be the normal waxy rice.

상기와 같이 비교회로(lC)의 비반전입력단(B)에 입력되는 저항치를 임의 설정함으로서 본 고안의 목적을 완성시킬 수 있는 것이므로 구조가 간단하며, 기존의 비교증폭회로의 비반전입력단에 절환스위치만 설치하면되는 실용적인 고안인 것이다.As described above, the purpose of the present invention can be completed by arbitrarily setting the resistance value input to the non-inverting input terminal B of the comparison circuit lC, so that the structure is simple, and the switch is switched to the non-inverting input terminal of the conventional comparison amplifier circuit. It is a practical design that only needs to be installed.
