PURPOSE: To keep the temperature of the boiled rice constant regardless of the boiled rice quantity and suppress the deterioration of the boiled rice by detecting the first and second pot temperatures, calculating the time required for the temperature change between both pot temperatures, measuring the boiled rice quantity in an inner pot, and controlling the electric power applied to a heating means.
CONSTITUTION: After rice is boiled by a rice cooker, the boiled rice temperature is lowered to the heat retaining temperature of about 72° by heat radiation, the temperature lowering rate at this time differs according to the boiled rice quantity, the lowering rate is large when the boiled rice quantity is small, and the lowering rate is small when the boiled rice quantity is large. The counting of the lowering time Δt, is started when the temperature of a pot temperature detector 4 reaches T1 (76°C) or below, the counting of Δt1 is completed when the pot bottom temperature reaches T2 (73°C) or below, the lowering time Δt, is fed to a controller 6 to judge the heat retaining boiled rice quantity, the heat retaining heating quantity at the time of heat retention is set in response to the heat retaining boiled rice quantity, and the heating quantity (electric power) is controlled.
