Heating control method, apparatus and device

A heating control method for a cooking device comprising a first heating tube, a second heating tube, and a cooking cavity formed between the first heating tube and the second heating tube for heating food, the method comprising the steps of:

• (a) obtaining a target heating mode of the cooking device, the target heating mode comprising a switching time point, one of a first magnitude relationship and a second magnitude relationship between heating temperatures of the first heating tube and the second heating tube, the first magnitude relationship being defined as the heating temperature of the first heating tube is greater than the heating temperature of the second heating tube,
• the second magnitude relationship being defined as the heating temperature of the first heating tube is less than the heating temperature of the second heating tube;
• and
• (b) controlling the heating temperatures of the first heating tube and the second heating tube to achieve a non-zero temperature difference between the heating temperatures of the first heating tube and the second heating tube and
• (c) when the switching time point is reached, controlling the temperatures of the first heating tube and the second heating tube by switching from the first magnitude relationship to the second magnitude relationship or vice versa so as to achieve an effect of turning the food;
• wherein step (a) comprises the steps of:
• in response to a customized cooking setup operation, obtaining a set target temperature value and a total heating duration to determine the target heating mode based on the target temperature value and the total heating duration;
• wherein the step (a) further comprises the steps of setting a number of switch time points based on the total heating duration.
