AI Technical Summary

Technical Problem

Existing methods for determining whether an electric slow cooker is dry-burning result in a high rate of misjudgment due to the slow heat conduction of the ceramic inner pot. This makes it impossible to accurately determine whether there is food inside the pot, posing a risk of explosion.

Method used

A combination of rapid preheating and heat release stages is employed. Temperature is collected at the heating position of the ceramic inner pot, and dry burning is determined by combining the slope of the temperature curve and the temperature difference. The accuracy of the determination is optimized by using multi-stage heating power control and environmental compensation coefficient.

Benefits of technology

It improves the reliability of dry burning detection, reduces the false alarm rate, ensures user safety, and optimizes preheating efficiency and environmental adaptability.

Abstract

This application relates to a method for determining dry burning in a cooking appliance, the cooking appliance itself, and a storage medium. The method includes: controlling a heating element to heat the inner pot for a first time; completing a rapid preheating stage when the first time reaches a preset first time threshold or the temperature at the heating position of the inner pot reaches a preset first temperature threshold; after the rapid preheating stage, controlling the heating element to stop heating for a second time to complete a heat release stage; acquiring a second temperature at the heating position of the inner pot after the rapid preheating stage and a third temperature after the heat release stage; and determining whether dry burning exists in the inner pot based on the second and third temperatures. This application solves the problems of misjudgment and low reliability in related technologies; by combining the second temperature after rapid preheating with the third temperature after the heat release stage, it quickly and accurately determines whether dry burning exists, reducing the probability of misjudgment and improving the reliability of dry burning determination.
