The invention relates to an electric
cooker and a rice-cooking heating control method. The electric
cooker comprises a
cooker body, an inner container, an upper cover device, a heating device for heating the inner container and food; wherein the outside of the bottom of the inner container is provided with a bottom temperature
detector for detecting temperature of the inner container, the upper cover device is provided with a cover temperature
detector for detecting temperature of the upper cover and a control device for controlling rice cooking; the control device comprises a main controller and a
timer and a memory respectively connected with the main controller; the output terminals of the bottom temperature
detector and the cover temperature detector are connected with the input terminal of the main controller, the output terminal of the main controller is electrically connected with the heating device. The rice-cooking control method of the invention at least comprises a first heating phase, a second heating phase and a first boiling phase; wherein in the second heating phase,
heating temperature and
heating time of the first boiling phase is determined by
heating time of the first heating phase, so that
moisture of small amount of rice can be fully evaporated and overflow can be prevented; in addition, early termination of heating due to abnormal conditions at the bottom of the inner container in the case of large amount of rice can be avoided, thus ensuring enough heating to ripen the rice.
