S220, judging whether the upper cover is opened or not according to the temperature value;
after the upper cover is opened, the temperature of the upper cover and/or the opening of the pot body is suddenly reduced, so that whether the upper cover is opened or not can be judged according to the temperature value of the upper cover and/or the opening of the pot body.
S231, if the upper cover is judged to be opened, adding 1 to the count value;
