Abstract
The invention discloses an electric pressure cooker boiling point judging method and an electric pressure cooker which are designed for solving the problem that an existing method is high in cost, and belongs to the field of pressure cookers and control methods thereof. The electric pressure cooker boiling point judging method comprises the steps that the ratio M1 of duration of every degree to duration of the last degree is recorded within the set temperature [T0, T1], and a maximum value MD is obtained; after the temperature in the cooker exceeds T1, the ratio M2 of duration of every degree to duration of the last degree is continuously recorded, and when it is found that M2 is larger than MD, it is judged that the electric pressure cooker reaches the boiling point; the set temperature [T0, T1] is a prejudged unboiled temperature interval, and when the temperature in the cooker is within the set temperature [T0, T1], the electric pressure cooker certainly does not reach the boiling point. The electric pressure cooker executes the boiling point judging method. According to the electric pressure cooker boiling point judging method and the electric pressure cooker, the structure of an existing electric pressure cooker does not need to be changed, a detection device does not need to be additionally added, the cost is low, and boiling point judging is accurate.
