본 고안은 버튼의 누름에 의하여 자동 취사되고, 취사후 자동보온되는 전기밥솥장치에 관한 것이다. 종래에 일반적인 전기밥솥은 밥솥내통을 열판위에 올려놓고 압압구를 눌러놓아야 취사가 개시되어 열판이 발열되고, 취사완료후에는 눌려진 압압구가 자동복귀되게 하는 구조의 것이었다.The present invention relates to an electric rice cooker which is automatically cooked by pressing a button and is automatically kept warm after cooking. Conventionally, the electric rice cooker has a structure in which a cooker is started by placing a pressure cooker on the hot plate and pressing the pressure port, and the hot plate is heated, and the pressed pressure port is automatically returned after the cooking is completed.
그러나 압압구의 압압작동이 불확실한 경우 취사가 되지 않으며 취사를 개시하기 위한 압압구조가 지나치게 단순한 구조이므로 고장이 잦은 결점도 있었다.However, when the pressing operation of the pressing tool is uncertain, the cooking is not possible, and the pressing structure for starting cooking is too simple, so that there are frequent defects.
따라서 압압구에 의한 압압수단이 아닌 버튼에 의한 순간 텃치로서 열판이 발열되고 열판의 발연후 취사완료시 자동으로 보온상태로 절환되는 장치가 필요로 된다.Therefore, there is a need for a device that heats the hot plate as an instant quench by a button, not a pressing means by a pressure port, and automatically switches to a warm state when cooking is completed after the hot plate is smoked.
본 고안의 목적은 버튼의 순간 첩촉으로서 취사가 개시되고 취사완료후 에는 보온으로 자동 절환되는 전기밥솥장치를 제공하고자 하는데에 그 목적이 있다.It is an object of the present invention to provide an electric rice cooker which is automatically switched to warming after cooking is started as a quick touch of a button.
이와같은 목적을 달성하기 위하여 본고안은 감응소자 저면에서 발열온도에 따라 자석이 탈티되어 접동봉이 마이크로 스위치를 접촉시키는 감응장치(가)와, 마이크로스위치, S.C.R의 게이트와 에노드 사이에 버튼스위치를 접속하고, 이 릴레이의 a접점은 취사용 히터와 접속하고, b접점은 보온용 히터에 접속하여서 되는 취사회로(나)로서 구성된다.In order to achieve this purpose, this paper proposes an induction device in which the magnet is detired according to the heating temperature at the bottom of the induction element so that the sliding rod contacts the micro switch, and the button switch between the micro switch and the gate and the anode of the SCR. The contact a of the relay is connected to the cooking heater, and the contact b of the relay is configured as a cooking furnace (b) connected to the heat keeping heater.
이를 첨부도면에 의거 더욱 상세히 설명하면 다음과 같다.This will be described in more detail based on the accompanying drawings.
본 고안은 전체적으로 감응장치(가)와, 취사회로(나)로서 이루어진다.The present invention is made up entirely of the response device (a) and the cooking furnace (b).
감응장치(가)는 감응판(7a)저면에 일체로 감응소자(7)가 구성되어 있고 이 저면에는 스프링(10) 의하여 접리되는 자석(8)이 접동봉(9)을 일체로하여 승강판(9a)에 구성되어 있다.The induction device (A) has a sensing element (7) integrally formed on the bottom of the sensing plate (7a), and a magnet (8), which is folded by a spring (10), is integrated with the sliding bar (9). It is comprised by (9a).
취사회로(나)는 제4도와 같이 마이크로스위치(A)와 S.C.R(1), 릴레이(2)를 차례로 접속구성하되 S.C.R(1)의 게이트와 에노드사이에 버튼스위치(3)을 구성하고, 릴레이(2)의 접점(2a)은 취사히터(4)에 접속 하고, 접점(2b)은 보온히터(4')에 접속됨과 동시에 또한, 취사회로(나)는 제5도와 같이 타이머접점(T1)(T2)을 S.C.R(1)의 애노드와 게이트사이에 연결함과 동시에 상기 접점(T1)(T2)사이에 릴레이(2')를 접속구성하고, 이 릴레이(2')의 접정(2a')은 타이머(5)와 함께 시한잗동라인을 이루고, 접정(2b')은 상기 릴레이 접정(2b)측에 접속 구성하여서 된다.As shown in FIG. 4, the microswitch A, the SCR 1, and the relay 2 are connected in order as shown in FIG. 4, but the button switch 3 is formed between the gate and the anode of the SCR 1, and the relay The contact 2a of (2) is connected to the cooking heater 4, the contact 2b is connected to the warming heater 4 ', and the cooking furnace (b) is the timer contact T 1 as shown in FIG. (T 2 ) is connected between the anode and the gate of the SCR (1), and at the same time, a relay 2 'is connected between the contacts T 1 and T 2 , and the relay 2' is connected. 2a 'forms the time limit operation line with the timer 5, and the contact 2b' may be connected to the relay contact 2b side.
미설명부호 6,6',6"는 파이롯드 램프, 11은 내통, 12는 스프링, 13은 외통이다.Reference numeral 6,6 ', 6 "is a pilot lamp, 11 is inner cylinder, 12 is spring, 13 is outer cylinder.
이와같이 구성된 본고안은 최초 쌀과 물이 혼합된 내통(11)을 밥솥의 열판위에 재치시킨뒤 버튼스위치(3)를 눌러주면(눌러진뒤 원복됨)제4도의 회로도와 같이 최초 도통상태의 마이크로 스위치(A)에 의하여 S.C.R(1)의 게이트에 신호 펄스가 가하여져 S.C.R(1)이 도통상태로 되어 릴레이(2)가 자화된다.In this configuration, the original rice and water mixed inner cylinder 11 is placed on the heating plate of the rice cooker and then the button switch 3 is pressed (pressed and retracted) as shown in the circuit diagram of FIG. By (A), a signal pulse is applied to the gate of the SCR 1, the SCR 1 is brought into a conductive state, and the relay 2 is magnetized.
릴레이(2)의 자화로서 접점(2a)을 도통상태로 되고, 접점(2b)은 끊어지게되어 취사용 히터(4)와 파일롯트 램프(6)가 발열 및 점등된다.As the magnetization of the relay 2, the contact 2a is brought into a conductive state, and the contact 2b is disconnected so that the cooking heater 4 and the pilot lamp 6 generate heat and light.
한편, 제3도의 (a)와같이 감응소자(7)와 자석(8)은 열판의 발연온도가 130°∼140°미만인 경우에는 항시 서로 붙어있게 되나 130°에 이르게 되면 자석(8)은 감응소자(7)로 부터 스프링(12)에 의해 탈리되게 된다.(대체적으로 열판온도가 125° 정도되게 되면 취사는 완료되게 된다)On the other hand, as shown in (a) of FIG. 3, the sensitive element 7 and the magnet 8 are always attached to each other when the temperature of the hot plate is less than 130 ° to 140 °, but when the temperature reaches 130 °, the magnet 8 is sensitive. It is detached by the spring 12 from the element 7. (In general, when the hot plate temperature is about 125 °, cooking is completed.)
자석(8)이 감응소자(7)로 부터 스프링(12)에 의해 탈리되면 제3도의(b)와 같이 접동봉(9)이 마이크로스위치(A)를 밀게 되므로 제5도의 회로에서 마이크로스위치(A)가 OFF되어 릴레이(2)가 자화력을 잃게 된다.When the magnet 8 is detached from the sensitive element 7 by the spring 12, the sliding rod 9 pushes the microswitch A as shown in FIG. 3 (b). A) turns off and the relay 2 loses the magnetizing power.
따라서 릴레이(2) 접점(2a)이 OFF되고, 접점(2b)이 ON되어 보온용 히터(4')가 발열되어 보온상태를 유지케 된다Therefore, the relay 2 contact 2a is turned off, the contact 2b is turned on, and the warming heater 4 'is heated to maintain the warm state.
특히, 본 고안은 제5도와 같이 취사개시전의 시간을 타임작동시켜 일정시간후 자동으로 취사를 개시하게 할수도 있다.In particular, the present invention may be able to automatically start cooking after a certain time by operating the time before starting cooking as shown in FIG.
즉, 최초 타이머(5)의 접점(T1)을 ON접속시켜 놓으면 접점(T2)측은 OFF되어 있으므로 릴레이(2')가 자화되게 된다.That is, when the contact T 1 of the first timer 5 is ON-connected, the relay T 'is magnetized because the contact T 2 side is OFF.
릴레이(2')의 자화로서 접점(2a')이 ON접속되고, 접점(2b')는 OFF된다.As the magnetization of the relay 2 ', the contact 2a' is connected ON and the contact 2b 'is turned OFF.
타이머(5)의 시한작동이 끝나면 접점(2a')은 OFF되고, 동시에 접점(T2)이 ON접속되어 S.C.R(1)의 게이트에 펄스가 가해져 S.C.R(1)이 도통된다.When the time limit operation of the timer 5 is completed, the contact 2a 'is turned off, and at the same time, the contact T 2 is connected on, and a pulse is applied to the gate of the SCR 1 to conduct the SCR 1.
S.C.R(1) 도통으로 릴레이(2)가 자화되며 릴레이(2)가 자화되면 접점(2a)이 ON되고, 접점(2b)은 OFF되어 취사용 히터(4)가 발열되어 열판이 가열되게 되는 것이다.When the relay 2 is magnetized by S.C.R (1) conduction and the relay 2 is magnetized, the contact 2a is turned on, the contact 2b is turned off, and the cooking heater 4 is heated to heat the hot plate.
이후 열판의 발연온도가 130°정도에 이르면 감응소자(7)로 부터 자석(8)이 탈티되어 ON도통증의 마이크로스위치(A)가 OFF되었다가 다시 ON상태로 원복되며, 릴레이(2)가 자화력을 잃더라도 접점(2b),(2b')은 항시 ON상태로 되므로 취사작동후 보온용 히터(4')가 작동되어 보온상태를 유지케 되는 것이다.After that, when the temperature of the hot plate reaches about 130 °, the magnet 8 is detired from the sensitive element 7 so that the micro switch A of OFF conduction is turned OFF and then restored to ON again. Even if the magnetizing power is lost, the contacts 2b and 2b 'are always in the ON state, so that the warming heater 4' is operated to maintain the warm state after the cooking operation.
이와같이 본 고안은 버튼스위치의 순간 도통으로 취사가 개시 및 환료될 뿐만 아니라 타이머(5)의 작동으로 원하는 시간에 자동 취사토록 할 수 있게되며 취사완료후에는 항시 자동으로 보온상태를 유지케 되므로 종래압압구에 의한 전기밥솥등이 갖는 구조적인 문제점을 완전히 개선케 되는 효과가 있다.In this way, the present invention not only can start cooking and refuel by instantaneous conduction of the button switch, but also enable automatic cooking at a desired time by the operation of the timer (5). There is an effect that completely improves the structural problems that the electric rice cooker and the like due to the pressure ball.
