Electric cooker and control method thereof

Abstract

The invention provides an electric cooker and a control method thereof. The control method comprises the following steps: after the electric cooker is started, the electric cooker is controlled to be heated at the first average power; when the temperature in the electric cooker reaches a first preset temperature, heating of the electric cooker is controlled to be stopped temporarily; first preset time later, the electric cooker is controlled to be continuously heated at the first average power; when the temperature in the electric cooker reaches a second preset temperature, the electric cooker is controlled to be heated at the second average power, wherein the first preset temperature is larger than the second preset temperature, the power regulation ratio of the second average power is smaller than that of the first average power and the power regulation cycle of the second average power is larger than that of the first average power; when the temperature in the electric cooker reaches a boiling balance temperature point, the electric cooker is controlled to be heated at the third average power so as to keep boiling; and second preset time later, heating of the electric cooker is controlled to be stopped. According to the electric cooker and the control method thereof, the fact that the electric cooker reaches boiling temperature and material in the electric cooker does not overflow can be guaranteed and temperature control is more accurate.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an electric rice cooker and a control method for the electric rice cooker. Background technique [0002] The rice cooker is a commonly used household appliance. At present, when the rice cooker cooks porridge, the temperature sensor is generally used to detect the temperature, and the rice water level and boiling state are judged during the heating stage. to ensure that the rice water boils and does not overflow. Specific process such as figure 1 As shown, it mainly goes through heating 01 stage, stopping 01 stage, heating 02 stage, stopping 02 stage and maintaining boiling stage. Among them, P01 is the temperature curve detected by the sensor at the bottom of the rice cooker, P02 is the water temperature curve, P03 is the temperature detected by the temperature sensor on the top cover of the rice cooker, and P04 is the heating pulse of the heater. The pulse is me...

AI Technical Summary

Problems solved by technology

[0003] Even if the existing electric rice cooker obtains the temperature through the temperature sensor on the upper cover, it still overflows or does not fully boil when cooking porridge or soup, the effect is unstable and the consistency is poor

In addition, the influence of ambient temperature will also lead to errors in the judgment of the boiling state and rice water level. For example, at the end of the heating stage, the water temperature does not reach the boiling temperature, and the judgment of the rice water level is too high, etc., which leads to non-boiling in the boiling stage. or the phenomenon of violent boiling and overflowing
