Boiling state detection method and cooking system applying the same

Abstract

The invention relates to a boiling state detection method. The method comprises the following steps of: detecting acquired weight data, calculating weight difference data of weight data change, comparing the weight difference data with a weight fluctuation threshold range corresponding to a boiling state, and then judging the boiling state. According to the boiling state detection method, the boiling state is not simply judged through a single change trend of weight, the judgment error caused by the influence of vibration brought by the boiling state on the weight is avoided, and the judgmenterror caused by material change is also avoided. The boiling state detection method is more accurate in judgment of the boiling state and wide in applicability. The invention further relates to a cooking system, which comprises a weight sensor arranged on a cooking utensil and a controller arranged in the cooking utensil, and the weight sensor is electrically connected to the controller. Accordingto the cooking system applying the boiling state detection method, the cooking state is judged more accurately in the working process, and use is more intelligent.

Description

technical field [0001] The invention relates to a boiling state detection method, and also relates to a cooking system. Background technique [0002] With the continuous improvement of people's living standards and the continuous iteration and intelligence of smart devices, smart cooking is currently a hot research topic in the cooking field. In the existing cooking equipment, weighing is used to identify whether to add or remove ingredients in the pot, so as to realize part of intelligent cooking, but the weighing function only stays at the weighing of food, and does not have other in-depth functional explorations. For example, the recognition of boiling soup. [0003] Authorized announcement number is CN104510329 (application number is 201510024278.7) Chinese invention patent "recipe generation system and cooking utensils for cooking utensils", in which the disclosed scheme calculates the weight loss of cooking materials at different cooking time points during the cooking...

AI Technical Summary

Problems solved by technology

However, the randomness of the user's operation during the cooking process is relatively high. It is judged as the boiling state only by the weight loss, and it is inevitable that the boiling state will be misjudged due to the artificial reduction of materials, and the applicability is poor.

[0004] In addition, the application publication number is CN107992808A (application number is 201711193739.9) Chinese invention patent "Boiling Vibration Acoustic Signal Time-Frequency Joint Feature Extraction and Boiling Recognition Method", in which the disclosed scheme uses the acoustic signal to identify the boiling of the liquid in the pot However, due to the interference of noise during the cooking process, the collected signals are difficult to process. At the same time, the algorithm and program for identifying boiling with sound wave information also have extremely high requirements for software and hardware, making it difficult to use sound waves to analyze boiling. and realizability
