KR970014653A - 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-term heat retention, and in particular, by setting the set temperature pattern to two types of high and low temperatures in the warming mode, The present invention relates to a method of controlling the temperature of an electric warming cooker that suppresses a change in the state of rice and reduces power consumption by maintaining warmth by intermittent control. Judging step, measuring the temperature of the hot plate by the temperature sensor to determine whether it is a high temperature or low temperature, and lighting of the indication lamp to confirm this at high temperature, each hot plate heater drive unit, body heater tri fluid drive unit, lid heater Lowering the temperature until the low temperature by cutting off the power of the triac driving unit, and display to confirm this at a low temperature There is a characteristic in the power to each heating plate heater driving part, the body heater triac drive unit, lid heater triac driver with the lighting of the program is to be run by raising the temperature to a high temperature until the guon.

Claims (4)

In the initial stage of thermal insulation, checking the input of the insulation key with the low temperature set, and checking the temperature of the hot plate by a temperature sensor to determine whether the temperature is high or low, and when the temperature is high, When the lamp is turned on, the power is lowered until the low temperature by cutting off the power of each hot plate heater driving part, the body heater tri fluid driving part, and the lid heater tri fluid driving part, and the hot plate heater driving part with the lighting of the display lamp which confirms this at low temperature. Method of controlling the thermal insulation temperature of the electric heat cooker characterized in that the power is applied to the body heater tri-liquid driving unit, the lid heater tri-liquid driving unit to increase the temperature to a high temperature until high temperature. The method according to claim 1, further comprising the step of setting the low temperature at the initial stage of thermal insulation during the control from the high temperature to the low temperature, thereby clearing the high temperature to return to the initial state. The method according to claim 1, further comprising: setting the initial temperature at the initial temperature when controlling the temperature from the low temperature to the high temperature, while clearing the low temperature to return to the initial state. The method according to claim 1, wherein the low temperature is set at 55 ° C, and the high temperature is set at 75 ° C. ※ Note: The disclosure is based on the initial application.
