Abstract: Addresses the limitations of smart gas stoves that rely on temperature sensor to identify boiling states, as well as the uncontrollable cooking outcomes caused by gas pressure fluctuations during smart recipe applications. An intelligent control solution based on weighing sensor is proposed. By monitoring cookware mass changes in real-time, boiling states are precisely identified. A regression model correlating evaporation rate with burner power and gas pressure is established. For soup-boiling/braising scenarios, evaporation patterns are investigated separately. Dynamic adjustment of burner power based on evaporation rates achieves precise control over the final volume of broth in cooked dishes. Utilizing weighing sensor signal values to achieve intelligent boiling recognition and dynamic burner power adjustment for gas stoves, enabling smart and precise cooking while enhancing user experience.
