step S106, if the first temperature rise rate is greater than a first preset slope threshold, the first preset power is reduced to a second preset power, then the cooking appliance is continuously heated, and a second temperature of the bottom of the cooking appliance is acquired;
when the first temperature rising rate is larger than a first preset slope threshold Bmn, the first preset power is reduced to a second preset power, then the cooking appliance is continuously heated, and a second temperature of the bottom of the cooking appliance is acquired; when the first temperature rising rate is less than or equal to the first preset slope threshold Bmn, the step S104 is continuously performed.
