To lose.

상술한 바와 같이 구성된 본 발명의 작용 및 효과를 상세히 설명하면 다음과 같다. 통상 취사공정을 마친후 보온공정이 진행되는데, 이때 기존에는 일정한 온도에 따라 단순히 열판과 보온히터를 온/오프제어하는 공정에 의해 밥솥내부 온도분포가 균일치 못하였던 현상이 있었으나, 본 발명은 이를 피하기 위해 열판 및 보온히터의 온/오프제어와 함께 온도상태에 따른 열량주기 및 히터량을 가변시킴으로서, 전체적으로 온도분포를 균일하게 유지하는 바, 이를 좀 더 부연하면, 우선 보온공정이 시작됨과 동시에 마이컴(30)은 온도감지부(20)를 통해 온도를 측정케하고(S1) 이를 입력단을 통해 입력받아 다음의 보온공정진행의 기준데이터로써 이용한다.Referring to the operation and effect of the present invention configured as described in detail as follows. In general, after the cooking process, the warming process is performed. In this case, there was a phenomenon in which the temperature distribution inside the cooker was not uniform by a process of simply turning on / off the heating plate and the warming heater according to a predetermined temperature. In order to avoid the heating plate and the heating heater on / off control by varying the heat cycle and the amount of heater according to the temperature state, to maintain a uniform temperature distribution as a whole, if more in detail, first the thermal process starts and at the same time 30 measures the temperature through the temperature sensing unit 20 (S1) and receives it through the input terminal and uses it as reference data for the next warming process progress.

즉, 상기한 마이컴(30)는 입력단을 통해 입력된 온도에 따라 제3도에 도시된 바와 같은, 열량주기별 데이터를 세트하여 보온공정이 진행개시되도록 하는 바, 여기서, 입력된 온도가 50℃이하이면 릴레이주기 8/14초, 히터량 100%인 열량주기1이 세트되어 가열진행되며 단계(S2-S3)와, 입력된 온도가 55℃이하이면 릴레이주기 6/14초, 히터량 100%인 열량주기2가 세트되어 가열진행하고(S4-S5), 입력된 온도가 60℃이하이면 릴레이주기 4/14초, 히터량 80%인 열량주기3로 세프되어 가열진행하며(S6-S7)와, 입력된 온도가 65℃이하이면 릴레이주기 2/14초, 히터량 60%인 열량주기4로 세트되어 가열진행하고(S8-S9)와, 입력된 온도가 70℃이하이면 릴레이주기 0/14초, 히터량 40%인 열량주기5로 세트되어 가열진행하며(S10-S11)와, 입력된 온도가 75℃이하이면 릴레이주기 0/14초, 히터량 20%인 열량주기6 세트되어 가열진행한다.(S12-S13).That is, the microcomputer 30 sets the calorie cycle-specific data as shown in FIG. 3 according to the temperature input through the input terminal to start the thermal insulation process, where the input temperature is 50 ° C. If it is less than 8/14 seconds of the relay cycle, the heat cycle 1 of 100% of the heater amount is set and proceeds to the heating step (S2-S3), and if the input temperature is less than 55 ℃ relay cycle 6/14 seconds, the heater amount 100% Phosphorus calorie cycle 2 is set and proceeds to heating (S4-S5), and if the input temperature is less than 60 ° C, it is cooked by heating the relay cycle 4/14 seconds and calorie cycle 3 with 80% of the heater quantity and heating (S6-S7). And, if the input temperature is 65 ℃ or less, it is set to relay cycle 2/14 seconds, the heat quantity cycle 4 of 60% of the heater amount and proceeds to heating (S8-S9), and if the input temperature is 70 ℃ or less, the relay cycle 0 / 14 seconds, the heating amount is set to the heat cycle 5, the heater amount 40% (S10-S11), if the input temperature is below 75 ℃ relay cycle 0/14 seconds, heater amount 2 A heat cycle of 0% is set at 6 and proceeds with heating (S12-S13).

이는 결국 전술한 바에서 살펴본 바와 같이, 저온에서 고온까지의 열판 및 보온히터의 가동이 온도상태에 따라 차별적으로 가열되므로서, 기존에 일정한 온도에 따라 가열제어되어 밥의 상태변화를 빠르게 초래하였던 단점을 피할 수 있게 된다.As a result, as described above, since the operation of the hot plate and the warming heater from low temperature to high temperature is heated differently according to the temperature state, the heat control is controlled according to a predetermined temperature, which causes the change of the rice state quickly. Will be avoided.

이와같이, 본 발명은 보온열량주기를 온도단계별로 지정되어 보온이 이루어짐으로서, 균일한 온도제어가 가능하게 되어 결과적으로 내부의 온도상태가 균일함에 의한 냄새가 적고, 밥상태가 양호한 밥을 획득할 수 있는 등의 유용한 효과가 있는 발명이다.As described above, the present invention is to maintain the heat insulation cycle is designated by the temperature step, the heat retention is made, uniform temperature control is possible, as a result, there is less smell due to the uniform internal temperature state, can obtain a good rice state rice It is the invention which has a useful effect, such as that.

이상의 설명은 본 발명의 일실시예에 불과하며, 본 발명의 그 구성요지 범위내에서 얼마든지 변경이 가능하다.The above description is only one embodiment of the present invention, and any change may be made within the scope of the present invention.
