본 고안은 1개의 타이머를 이용하여 타이머 예약시간에 의한 기존의 밥취사기능에 죽취사기능을 첨가한 보온 밥솥 회로에 관한 것이다.The present invention relates to an insulated rice cooker circuit that adds porridge cooking function to the existing rice cooking function by the timer reservation time using one timer.

종래의 전기밥솥은 취사히타가 일정온도에 도달하면 오븐밑면에 밀착된 마그네트스윗치내의 페라이트 자성체가 열에 의해 자성을 잃어 떨어짐과 동시에 자동적으로 보온히타로 인해 보온되는 구조로 된것이므로 은근한 열로서 지속적인 가열을 필요로 하는 죽을 겸용하여 취사할 수 없는 폐단이 있었다.The conventional electric rice cooker is a structure in which the ferrite magnetic material in the magnet switch in close contact with the bottom of the oven loses its magnetism due to heat and is automatically insulated by the warmth heater when the cooking temperature reaches a certain temperature. There was a pulpit that could not be combined with the need of porridge.

본 고안은 이와같은 점을 감안하여 죽취사기능도 겸용하는 밥솥을 안출하므로서 종래의 결점을 일소한것인데 이를 첨부도면에 따라 상술하면 다음과 같다.The present invention is to eliminate the drawbacks of the prior art by devising a rice cooker that also combines the function of porridge in consideration of the above point, as described above according to the accompanying drawings.

도선(L1)(L2)간에 타이머(T), 선택스윗치(SW1)(SW2)(SW3)(SW4), 취사스윗치(SW5), 보온히타(H1), 취사히타(H2)를 각각 연결한것에 있어서 선택스윗치(SW1)D와 (SW2)의 사이에 자동온도제어소자(TS1)(TS2)(서머스타트 : thermostat)를 병렬로 연결하여서 됨을 특징으로 하는 것이다.The timer T, the selector switch SW1, the switch SW2, the switch SW3, the switch SW5, the insulation heater H1, and the heater H2 are connected between the conductors L1 and L2. In this case, the automatic temperature control elements TS1 and TS2 (thermostat: thermostat) are connected in parallel between the selection switches SW1 and SW2.

도면중 미설명부호 LP1은 예악타이머램프이고 LP2는 죽램프이며 LP3는 보온램프이고 LP4는 취사램프이며 TRS는 열감지스윗치이고 RY는 릴레이이다.In the figure, reference numeral LP1 is a preliminary timer lamp, LP2 is a bamboo lamp, LP3 is a warm lamp, LP4 is a cooking lamp, TRS is a heat sensing switch, and RY is a relay.

이와같이된 본 고안은 선택스윗치(SW1)(SW2)(SW3)(SW4)를 밥공정으로 선택한후 취사스윗치(SW5)를 누르면 보온히타(H1)는 작동하지 않고 취사히타(H2)에만 전원이 인가되어 취사램프(LP4)의 점등과 동시에 취사공정이 시작되고 밥이 다되면 오븐밑면에 밀착된 취사스윗치(SW5)의 페라이트 자성체가 열에 의해 자성을 잃어 떨어짐과 동시에 자동적으로 보온히터(H1)가 가열보온이 되는 것은 공지된 바와 같다.According to the present invention, the selection switch (SW1) (SW2) (SW3) (SW4) is selected by the rice process, and then pressing the cooking switch (SW5), the insulation heater (H1) does not operate and the power is supplied only to the cooking heater (H2). As soon as the cooking lamp (LP4) is turned on and the cooking process starts, when the rice is finished, the ferrite magnetic material of the cooking switch (SW5) in close contact with the bottom of the oven loses its magnetism due to heat and the heating heater (H1) automatically heats up. Keeping warm is known.

본 고안은 바이메탈로서 자체적으로 온도를 검출하여 온, 오프되는 자동온도 제어소자(TS1)(TS2)를 병렬로 연결하여 은근한 열로서 죽을 취사할수 있도록 한것을 특징으로 한 것인바 본 고안의 자동온도제어소자(TS1)(TS2)는 밥솥의 상하부 즉 한개의 자동온도제어소자(TS1)는 취사히타(H2)가 설치된 밥솥의 하부에 부착하고 다른하나의 자동온도제어소자(TS2)는 뚜껑부위에 부착하여 하부의 자동온도제어소자(TS1)가 일정한 열에 단절되면 이와 병렬로 연결된 상부 뚜껑부위에 부착된 자동온도제어소자(TS2)에 의해 계속적으로 취사히터(H2)가 가열되어 내용물을 완전히 익혀주므로서 죽을 취사하게 되는 것이다.The present invention is characterized in that the automatic temperature control element (TS1) (TS2) that is on and off by detecting the temperature itself as a bimetal connected in parallel so that it is possible to kill the heat by the subtle heat. The elements TS1 and TS2 are attached to the upper and lower parts of the rice cooker, that is, one thermostat TS1 is attached to the lower part of the rice cooker where the cooking heater H2 is installed, and the other thermostat TS2 is attached to the lid part. When the lower temperature control element TS1 is disconnected in a certain heat, the cooking heater H2 is continuously heated by the automatic temperature control element TS2 attached to the upper lid part connected in parallel, thereby fully cooking the contents. You will be cooking porridge.

보다 상세히 설명하면 선택스위치(SW1)(SW2)(SW3)(SW4)를 죽공정으로 선택하고 죽종류에 따라서 죽취사시간을 선택하여 타이머(T)를 셋팅시키면 자동온도제어소자(TS1)(TS2)를 통하여 전원이 공급된다.In more detail, if the selector switches SW1, SW2, SW3, and SW4 are selected as the bamboo process and the bamboo cooking time is set according to the type of porridge and the timer T is set, the automatic temperature control element TS1 (TS2) is used. Power is supplied through).

이 상태에서 취사스윗치(SW5)를 누르면 취사히타(H2)가 가열되어 내용물을 익히게되고 시간이 흘러 점차 온도가 상승하면 취사히타(H2)측에 부착된 자동온도제어소자(TS1)가 뚜껑측의 자동온도제어소자(TS2)보다는 먼저 기준온도를 감지하여 OFF된다.In this state, when the cooking switch SW5 is pressed, the cooking heater H2 is heated to learn the contents, and when the temperature gradually rises over time, the automatic temperature control element TS1 attached to the cooking heater H2 side is closed. The reference temperature is sensed before the automatic temperature control element TS2 is turned off.

그러나 취사히타(H2)는 하부측에 부착된 자동온도제어소자(TS1)가 OFF되어도 병렬로 연결된 뚜껑부위의 자동온도제어소자(TS2)에 의해 계속 전원이 공급되고 취사히타(H2)에 의해 내용물이 끓어서 올라오는 중기에 의하여 셋팅된 온도에 이르렀을때 뚜껑쪽에 붙어있는 자동온도제어소자(TS2)가 OFF되며 자동온도제어소자(TS2)가 OFF될 때에는 이의 내용물이 거의 익혀지게 된다.However, even if the thermostat TS1 attached to the lower side is turned off, the cooking heater H2 is continuously supplied with power by the thermostat element TS2 on the lid part connected in parallel, and the contents are supplied by the cooker H2. When the temperature set by the boil-up medium is reached, the thermostat TS2 attached to the lid is turned off, and its contents are almost cooked when the thermostat TS2 is turned off.

여기서 자동온도제어소자(TS2)는 뚜껑쪽에 붙어있어 취사히타(H2)의 직접열에 의한 온도제어를 하지 않기 때문에 한번 OFF되면 뚜껑을 열어 완전히 식혀주지 않는한 동작을 하지 않게 되며 자동온도제어소자(TS2)가 OFF되면 이미 OFF된 자동온도제어소자(TS1)도 같이 동작을 하지 않으므로 전원이 차단되어 취사히터(H2)가 식게됨에 따라 이때부터는 빨리 ON, OFF되는 하부쪽에 붙어있는 자동온도제어소자(TS1)의 온도제어에 의해 서서히 죽이 되는 것이다.Since the automatic temperature control element TS2 is attached to the lid side and does not control the temperature by direct heating of the cooking heater H2, once it is turned off, the automatic temperature control element TS2 does not operate unless it is completely cooled. When the) is turned off, the thermostat (TS1) that is already turned off does not work together, so the power is cut off and the cooking heater (H2) cools down. Is gradually killed by temperature control.

이는 재래방식의 죽취사에 있어서 강한 불로서 내용물을 익혀준다음 약한불로서 서서히 죽을 끓이는것과 같은 것이다.This is the same as cooking the contents with a strong fire and then slowly boiling porridge with a weak fire.

또한 선택스윗치(SW3)를 빼고 전후 회로를 바로 연결해줄 경우에는 즉 취사 타이머(T)만 셋팅시키고 취사스위치(SW5)를 누르지 않았을경우 죽램프(LP2)와 보온램프(LP3)가 동시에 점등되어 이상작동 상태임을 알려주는 경고장치로서 활용할수 있다.In addition, when removing the selection switch (SW3) and connecting the front and rear circuits immediately, that is, when only the cooking timer (T) is set and the cooking switch (SW5) is not pressed, the bamboo lamp (LP2) and the warm lamp (LP3) are turned on at the same time. It can be used as a warning device to indicate operation status.

그리고 뚜껑에 부착된 자동온도제어소자(TS2) 대신에 제2도에 도시한바와 같은 TRS와 릴레이(RY)를 사용한 온도검출장치(P)를 연결구성하였을 경우에도 상술한 바와 같은 동일원리로 밥과 죽을 겸용하여 취사할수 있다.The same principle as described above is applied even when the temperature detecting device P using the TRS and the relay RY as shown in FIG. 2 is connected instead of the thermostat TS2 attached to the lid. You can cook with and porridge.

이와같이 본 고안은 기존의 밥솥에 자동온도제어소자(TS1)(TS2)를 병렬로 연결하여 소망하는 설정온도를 자동 조절할 수 있으므로 죽취사뿐 아니라 각종 조리물을 찌거나 끓이는 찜솥으로도 사용이 가능하여 가정에서 다목적으로 사용할 수 있는 효과가 있다.As such, the present invention can automatically adjust the desired set temperature by connecting a thermostat (TS1) (TS2) in parallel to the existing rice cooker, so it can be used as a steaming pot for steaming or boiling various kinds of food as well as porridge. It has a multipurpose effect at home.
