AI Technical Summary

⚠Technical Problem

Existing electromagnetic heating rice cookers cannot control energy consumption based on the user's opening behavior, resulting in temperature fluctuations inside the pot that affect cooking results and energy consumption.

⚗Method used

By acquiring records of users opening the lid during the cooking process, a database of user lid-opening behavior features is built. Based on the current cooking mode and stage, the reheating temperature and power are adjusted, and the reheating power is lowered to the temperature adjusted when the lid is opened, thus avoiding energy waste caused by frequent lid opening.

🎯Benefits of technology

This technology enables energy-saving control of the electromagnetic heating rice cooker based on the user's lid-opening behavior, avoiding the impact of frequent heating and cooling on the taste of food, and improving cooking efficiency and energy saving.

Abstract

The application belongs to the field of electric rice cooker control, and discloses an electromagnetic heating electric rice cooker heating electric control method and system based on a temperature sensor. A user cover opening behavior feature library is constructed. When a cover opening trigger signal is detected, the current cooking mode, cooking stage and current pot temperature measured by the temperature sensor are synchronously acquired. After the cover opening operation is completed, the expected cover opening times and duration in the subsequent preset period are determined by the feature library in combination with the current cooking mode and stage, and the standard temperature and power for temperature recovery in the corresponding scene are called. If the expected cover opening times are greater than or equal to 1, the temperature recovery temperature in the current temperature recovery stage is set to a cover opening adjustment temperature which is 3-5 DEG C lower than the standard value, and the temperature is recovered to the adjustment temperature by using a low-grade temperature recovery power which is lower than the standard power. The application can control the cooking process of the electromagnetic heating electric rice cooker in an energy-saving manner in combination with the cover opening behavior of the user.
