Description

Technical field

[0001] The invention relates to a gas stove overheating anti-air burning device based on a single-chip microprocessor intelligent control and a control method thereof. Background technique

[0002] Gas stoves are very popular in household use. At present, most of the gas stoves produced on the market use mechanical means to control the gas, and the main purpose is to overcome the midway flameout and shut down. There is no device and method for preventing overheating and air burning with a single-chip microprocessor intelligently. , It is more difficult to protect the safety of users. Summary of the invention

[0003] In order to overcome the above shortcomings, the present invention provides a gas stove overheating and empty burning prevention device and method. The device and method not only have the traditional low temperature flameout protection function, but also add intelligent high temperature protection through overheat detection and overheat curve. Discrim...
