The invention discloses an anti-overflow detection device for a cooking utensil and the cooking utensil. The anti-overflow detection device comprises a conductor, an insulator and a capacitance detection chip, and the conductor comprises a first conducting part and a second conducting part; the insulator at least comprises a first insulating wall covering the lower surface of the first conductingpart and a second insulating wall covering the lower surface of the second conducting part, the lower surface of the first insulating wall constitutes a first detection surface, the lower surface of the second insulating wall constitutes a second detection surface, and the capacitance value of the conductor changes with a medium in contact with the first detection surface and the second detectionsurface; the capacitance detection chip detects the change quantity of the the capacitance value of the conductor to generate a detection signal. The anti-overflow detection device for the cooking utensil can improve the heating effect of the cooking utensil and has the advantages of being low in cost, high in reliability and the like.
Description
technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to an anti-overflow detection device for cooking utensils and a cooking utensil having the anti-overflow detection device for cooking utensils. Background technique [0002] Cooking utensils such as electric rice cookers are usually equipped with an overflow detection device in order to realize the anti-overflow function. The anti-overflow detection device applied to cooking utensils in the related art realizes the detection of the overflow signal by detecting the resistance characteristic of water, and needs to install at least two probes, which is costly and has a high probability of misjudgment. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. Therefore, the present invention proposes an anti-overflow detection device for cooking utensils,...
