2. Description of the Related Art Electric rice porridge cookers currently on the market are provided with a heater at the bottom of an inner pot, and heating power is supplied to the heater to cook porridge.

Further, for the purpose of cooking delicious porridge, the temperature of the porridge cooking pot is measured by a controller equipped with a temperature sensor and a microcomputer as shown in FIG. An electric rice porridge cooker controlled by a microcomputer has been developed, which is input to a microcomputer to determine the porridge cooking capacity and perform appropriate power control according to the cooking capacity. An electric porridge cooker that cooks under the control of a microcomputer performs cooking process control such as a water absorption process, a cooking capacity determination process, a cooking process, and a boiling maintenance process in sequence under the program control of a microcomputer, and the porridge is in an optimal state. After cooking and porridge cooking control, the heat retention control state is entered. Thus, in the electric rice porridge cooker controlled by a microcomputer, the control of the cooking process can be finely controlled by the program control, so that delicious rice porridge can be cooked.
