KR970014652A - Insulation temperature control method of electric rice cooker - Google Patents

Abstract

The present invention relates to a method of controlling an electric thermal rice cooker, which is advantageous for long time warming, and in particular, when a long-term heat keeping key is initially input in a warming mode, it is kept at a temperature below a preset temperature, that is, a low temperature, while releasing the long-term warming key. The present invention relates to a method of controlling an insulation temperature of an electric insulation rice cooker, which is adapted to improve the state of rice with respect to the work time by simple key operation by returning to a temperature suitable for eating rice, which is a high temperature insulation temperature, which has been previously set. A first step of confirming and determining the input of the long-term heat preservation key at the initial stage in the warming mode; a second step of checking the temperature of the hot plate by a temperature sensor when the input of the long-term heat preservation key is confirmed; and the temperature measured in the second step And a third step of judging the temperature set to a predetermined value and differentially controlling the hot plate heater, the trunk heater and the lid heater according to the result. When the temperature is higher than or equal to the predetermined value, it is composed of the fourth step of waiting for the temperature input and the fifth step of confirming the key off of the long-term insulation key after the fourth step. It is characterized in that it is determined whether to keep at a temperature or to perform with a normal thermal mode routine.
