Abstract

PURPOSE: To improve the taste and easily find the progress degree of gelatinization by providing a rice cooker with rice cooking process completion detecting means, boiling detecting means, timer means for counting the time necessary for gelatinization of starch, display means for displaying the gelatinization process stepwise on the basis of its output, and heating value control means. CONSTITUTION: When it is detected by a lid sensor 4 and a boiling detecting means 7 that rice reaches the boiling temperature, the time necessary for gelatinization is counted by timer means 8, the residual time is displayed on a residual time indicator 20, and a first lamp 1 of lamps displaying the gelatinization process is lighted. When the residual time is 10 minutes, for example, a second lamp 18 is additionally lighted. In the counting period, a heating element 2 is controlled so that the rice temperature by the lid sensor is 100 deg.C or more. When it is detected by a rice cooking process completion detecting means 5 that the detected temperature by a pan bottom sensor 3 was raised to a rise cooking process complete point, a heating value control means 6 tuns off the heating elements 2 to transfer the process to steaming process. Thereafter, the gelatinization and steaming process are completed by the count termination signal by the timer means 8.
