Description

technical field

[0001] The invention relates to an anti-dry-burning device for gas cookers with self-generating function, and belongs to the technical field of anti-dry-burning for cookers. Background technique

[0002] With the development of kitchen culture, various anti-dry cooking utensils have been born one after another. Anti-dry cooking utensils can complete the work of detecting dry-boiling, alarming and stopping dry-boiling. The principle is to collect the temperature of the pot body by placing the temperature sensor inside the cooker or close to the outside of the cooker, and then analyze the collected temperature information through a single-chip microcomputer. After it is judged to be dry burning, control the alarm device to alarm or directly cut off the power supply or gas source to achieve the purpose of preventing dry burning. The Chinese patent "Anti-dry Burning Gas Cooker", the publication number is CN202561827U, and the publication date is 20121128, disclo...
