The invention belongs to the field of household appliances, and in particular relates to an electric
cooker and a heating control method thereof. The electric
cooker comprises a pot body, a pot cover, an inner pot and a heater arranged under the inner pot; the inside of the pot body is provided with a control part and a temperature sensor; the control part comprises a main controller, a first
timer, a second
timer, a temperature incremental memory and a total working time memory; and the main controller is electrically connected with the heater, the temperature sensor, the first
timer, the second timer, the temperature incremental memory and the total working time memory respectively. The heating control method comprises a preheating stage A and a heating and temperature rising stage B; and in the heating and temperature rising stage B, the main controller controls the heater to continue heating or to finish the heating and temperature rising stage B according to an inner pot
temperature increment delta T correspondingly generated in a unit time
delta t timed by the second timer, a
temperature increment preset in the temperature incremental memory, a total working time t timed by the first timer and a total working time preset in the total working time memory. The method can accurately judge the quantity and boiling state of food in the
cooker, has the advantages of simple control and low cost, and is suitable for various electric stewpots and
ceramic pots with separated upper covers.
