Electric cooker and heating control method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the field of household electrical appliances, in particular to an electric cooker capable of accurately detecting the temperature and boiling state of food, and also relates to a heating control method of the electric cooker. Background technique [0002] Computerized electric cooking utensils currently on the market, such as purple casserole, electric rice cooker, etc., generally use a temperature sensor at the bottom of the pot body to sense whether the temperature at the bottom of the pot reaches a preset temperature value, thereby indirectly judging the boiling state of the food. The above temperature preset values ​​are all higher than the boiling point of water. When there is a difference in the amount of cooking, such as cooking a small amount of food, when the temperature at the bottom of the pot reaches the preset temperature value, the food in the pot is often boiling. It is difficult to avoid the phenomenon of overfl...
