Electric cooker and porridge-cooking control method thereof

Abstract

The invention relates to an electric cooker and a porridge-cooking control method thereof. In the electric cooker, a temperature memory is preset with a second temperature T2 and a third temperature T3 and T2 is less than or equal to T3; a time memory is preset with a first boiling time t3 and a second boiling time t4; a heating power memory is preset with a second power ratio B, a third power ratio C and a fourth power ratio D corresponding to rice quantity grades; a main controller is provided with a control module; after the electric cooker is used for heating and finishes the first boiling time t3 by the second power ratio B at the boiling stage, a heating device is controlled to heat by the third power ratio C or the fourth power ratio D according to a ratio of an upper cover temperature T to the second temperature T2 and the third temperature T3 until the set second boiling time t4 is met. Heating power is changed according to the upper cover temperature at the boiling stage, so the defect that rice and water are not boiled completely under low voltage or low environmental temperature is overcome, and the porridge-cooking effect is effectively improved.

Description

technical field [0001] The invention belongs to the field of cooking control of an electric rice cooker, in particular to an electric rice cooker and a porridge cooking control method thereof. Background technique [0002] For various computer-type rice cookers currently on the market, in the process of cooking porridge or soup, the work control process generally sets the initial temperature detection stage, heating control stage, stop control stage, and boiling control stage; the length of working time through the heating control stage , to determine the level of rice water in the pot, and then set a fixed heating power corresponding to the level of rice in the boiling control stage for continuous heating to maintain the porridge in a boiling state until the end of the porridge cooking process. However, this control method is easily affected by the working voltage of the rice cooker and the ambient temperature. When cooking porridge or soup under the condition of low voltag...

AI Technical Summary

Problems solved by technology

However, this control method is easily affected by the working voltage of the rice cooker and the ambient temperature. When cooking porridge or soup under the condition of low voltage or low external ambient temperature, the effect of cooking porridge or soup is poor, especially when the amount of rice is large. , the rice water is not fully boiled, resulting in the rice grains not blooming, and the porridge water is relatively clear and not strong enough, which will easily lead to dissatisfaction with customers
