This is a change in the state of the rice rapidly while the water is kept in a supersaturated state and the remaining gas remains in a state of keeping warm.

이에따라, 보온공정시에도 수시로 밥솥내부에 계속적으로 잔존하고 있는 잔류가스를 제거하는 방법이 요구되어 왔다.Accordingly, there has been a demand for a method of removing residual gas remaining in the rice cooker continuously during the warming process.

여기서, 상기 제2단계에 의한 설정시간은 30분으로 지정되도록 한다.Herein, the setting time according to the second step is designated as 30 minutes.

상술한 바와 같이 구성된 본 발명의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effect of the present invention configured as described in detail as follows.

통상취사공정이 마친상태후 본 발명에 따른 보온공정이 개시되는데, 이때 보온공정이 시작과 동시에 마이컴(40)은 타이머부(30)을 제어하여 타이머카운트가 진행되도록 한다(S100). 그리고, 이 타이머 카운트의 진행과 함께 온도감지부(20)를 통해 온도를 측정케하고(S101) 보온공정진행에 기준데이터로써 이용한다.After the normal cooking process is finished, the warming process according to the present invention is started. At this time, as the warming process starts, the microcomputer 40 controls the timer unit 30 to advance the timer count (S100). Then, the temperature is measured through the temperature sensing unit 20 with the progress of the timer count (S101) and used as reference data for the progress of the thermal insulation process.

상기한 타이머카운트가 본 발명에서 설정한 시간(제품출하시 30분으로 설정한다.)에 도달하였는가를 판정하여 설정시간이내로 판별되면 초기에 온도측정한 데이터를 세트하여 그 결과로써 보온공정이 진행토록 하는 바, 즉, 60℃이하인 것으로 판정되면 마이컴(40)은 열판히터구동부(50)와 보온히터구동부(60)를 구동제어하여 재가열하는 동작을 진행하고, 60℃이상 75℃이하인 것으로 판정되면 보온히터구동부(60)만 구동제어하여 보온동작이 이루어지도록 진행하는 한편, 75℃이상인 것으로 판정되면 보온히터구동부(60)를 구동오프 시켜 모든 히터가 오프된 상태에서 보온이 진행토록 하고 초기의 상태로 리턴되도록 제어한다.It is determined whether the timer count has reached the time set in the present invention (set to 30 minutes at the time of shipment). If it is determined within the set time, the temperature measurement data is set initially to allow the thermal insulation process to proceed. That is, when it is determined that the temperature is 60 ° C. or less, the microcomputer 40 proceeds with the operation of reheating by controlling the hot plate heater driving part 50 and the warming heater driving part 60, and when determined to be 60 ° C. or more and 75 ° C. or less While only the heater driving unit 60 is driven to proceed with the warming operation, and when it is determined that the temperature is 75 ° C. or higher, the warming heater driving unit 60 is driven off so that the warming proceeds in the state where all the heaters are turned off and the initial state is maintained. Control to return.

반면, 상기한 타이머카운트가 본 발명에서 설정한 시간(제품출하시 30분으로 설정한다.)에 도달하였는가를 판정하여 설정시간에 도달한 상태로 판정되면 본 발명에 따른 잔류가스를 제거하는 단계의 동작으로 진행한다. 즉, 마이컴(40)은 출력단에 하이전위를 인가하면 그 인버터(I1)에 의해 반전된 신호로 릴레이(RY)의 코일부가 자화되고, 그 스위치부가 온되므로써 결국 전원(AC)이 솔레노이드밸브(SV)에 인가되어 솔레노이드밸브(SV)가 온된다(S103). 이 솔레노이드밸브(SV)온 상태는 밥솥내부의 증기압의 순간적으로 배출되면서 잔류가스를 제거하게 된다. 이와같은 배출진행상태에서 마이컴(40)은 소정의 시간(약10초)을 카운트하여(S104) 이 시간이 경과된 것으로 판정되면 솔레노이드밸브구동부(70)로 로우전원을 인가하여 솔레노이드밸브(SV)가 오프상태가 되도록 제어한다(S105). 그 제어동작은, 마이컴(40)은 출력단에 로우전원을 인가하면 그 인버터(I1)에 의해 반전된 신호로 릴레이(RY)이 코일부가 비자화되고, 스 스위치부가 오프되므로서 결국 전원(AC)이 차단되어 솔레노이드밸브(SV)가 오프된다.On the other hand, it is determined whether the timer count has reached the time set in the present invention (set to 30 minutes at the time of product shipment). If it is determined that the set time has been reached, the step of removing residual gas according to the present invention is performed. Proceed to action. That is, when the microcomputer 40 applies a high potential to the output terminal, the coil part of the relay RY is magnetized by the signal inverted by the inverter I1, and the power supply AC is finally turned on by switching on the switch part. The solenoid valve SV ), The solenoid valve SV is turned on (S103). The solenoid valve (SV) on state removes residual gas while momentarily releasing the steam pressure inside the cooker. In this discharge progress state, the microcomputer 40 counts a predetermined time (about 10 seconds) (S104) and when it is determined that the time has elapsed, the low power is applied to the solenoid valve driving unit 70 to provide the solenoid valve SV. Is controlled to be off (S105). In the control operation, when the microcomputer 40 applies a low power source to the output terminal, the relay RY is non-magnetized by the signal inverted by the inverter I1, and the switch unit is turned off. The solenoid valve SV is turned off.

결국, 이는 짧은시간동안만 잔류가스가 제거되도록 함으로서, 수분의 증발이 극소화되도록 한다.In turn, this allows residual gas to be removed only for a short time, thereby minimizing the evaporation of moisture.

그와동시에 마이컴(40)은 초기에 설정한 30분의 시간을 클리어시키는 제어출력을 인가한 다음 처음의 상태로 복귀하여 제동작하도록 한다(S106).At the same time, the microcomputer 40 applies a control output for clearing the initially set time of 30 minutes and then returns to the initial state to operate it (S106).

이와같이 본 발명은 보온공정중 잔류압력을 주기적으로 제거하는 공정을 추가로 신설함으로써, 밥솥내부의 압력을 항시 대기압상태로 유지시켜 잔류가스로 인한 밥상태변화를 방지하여 줌으로써, 보온성능이 향상되도록 한 유용한 발명이다.As described above, the present invention further establishes a process of periodically removing residual pressure during the thermal insulation process, thereby keeping the pressure in the rice cooker at atmospheric pressure at all times to prevent changes in the rice state due to residual gas, thereby improving thermal insulation performance. It is a useful invention.

이상의 설명한 본 발명의 일실시예에 불과하며, 본 발명의 그 구성요지 범위내에서 얼마든지 변형이 가능하다.It is only one embodiment of the present invention described above, and any modification can be made within the scope of the present invention.
