Abstract

The invention discloses a surge detection circuit, a surge detection method and a cooking utensil. The surge detection circuit comprises a voltage dividing device, a filtering device, a coupling device and a control chip, wherein the voltage dividing device is respectively connected with the filtering device and the coupling device, the filtering device and the coupling device are connected to a first pin of the control chip, and circuit input voltage is divided through the voltage dividing device, and is transmitted to the control chip through the filtering device and the coupling device. According to the invention, the technical problem that the circuit of a household appliance is easy to damage due to the lack of a circuit for effectively detecting the surge in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of home appliance manufacturing, in particular to a surge detection circuit, a detection method and a cooking utensil. Background technique [0002] When the circuit is struck by lightning and when the inductive load or large load is turned on or off, a high operating overvoltage is often generated. This instantaneous overvoltage (or overcurrent) is called surge voltage (or surge current), which is A transient disturbance. [0003] However, in the application process of existing home appliance circuits, transient interference from external power sources is often encountered. Among them, the transient interference is usually generated by power grid fluctuations. How to effectively detect surge generation in home appliance circuits? has become an urgent problem to be solved. [0004] No effective solution has been proposed for the above-mentioned problem that the circuit of the home appliance is easily damag...
