Abstract

The invention discloses an electric cooking utensil, an anti-overflow fault detection device and an anti-overflow fault detection method thereof. The anti-overflow fault detection method comprises thefollowing steps: obtaining capacitance value if a foam detection device in a real-time manner after the electric cooking utensil enters a heating phase; determining that steam foams are detected whendifference value between current capacitance value of the foam detection device and capacitance reference value is larger than first pre-set threshold value and obtaining duration of detecting steamfoams; updating the capacitance reference value according to the current capacitance value of the foam detection device if the duration is larger than first pre-set time and controlling the electric cooking utensil to continuously heat foams till the electric cooking utensil enters a boiling phase; and determining an anti-overflow detection fault occurs if difference value between the current capacitance value of the foam detection device and the updated capacitance reference value is smaller than or equal to first pre-set threshold value after the electric cooking utensil enters the boiling phase. Therefore, the electric cooker can continuously cook by avoiding erroneous judgments in order to fully satisfy the usage requirement of a user.

Description

technical field [0001] The invention relates to the technical field of cooking appliances, in particular to an anti-overflow fault detection method of an electric cooker, an anti-overflow fault detection device for an electric cooker and an electric cooker. Background technique [0002] When an electric cooker in the related art, such as an electric rice cooker, detects overflow, it will trigger the electric cooker to stop heating. If overflow is detected for a long time, the electric cooker will stop heating for a long time, resulting in the end of cooking. , the cooking cannot be completed, affecting the user's use. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. For this reason, an object of the present invention is to propose an anti-overflow fault detection method of an electric cooker, which can effectively detect whether an anti-overflow detection ...
