Liquid overflow detection method and device, pot, and electromagnetic heating assembly

Abstract

The invention provides a liquid overflow detection method and device, a cooker, and an electromagnetic heating assembly. The liquid overflow detection method includes: during the process of heating the liquid, generating a sound signal according to the sound state of the liquid; according to the change of the sound signal Trend judges whether the liquid is in a state to be overflowed. The invention can accurately and reliably detect liquid overflow while ensuring that the liquid in the pot is cooked, and then can effectively prevent the liquid in the pot from overflowing.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a liquid overflow detection method and device, a pot, and an electromagnetic heating assembly. Background technique [0002] With the rapid development of social economy and science and technology, time has become the most precious wealth for people, but cooking, as a necessary basis of life that cannot be obtained by human beings, requires a certain amount of time. Therefore, cooking efficiency has become a requirement of people. And the focus of attention, especially liquid foods such as porridge or soup, among them. The high-power characteristics of the induction cooker make it the first choice for people to cook porridge or soup. However, although the process of cooking porridge or soup with an induction cooker is relatively fast, it still takes a few minutes to ten or twenty minutes to boil the soup. During the whole process of cooking porridge or soup, the user ne...

This will inevitably bring a great waste of time and trouble to the user, making the user unable to focus on other things

[0003] At present, some induction cookers on the market have been equipped with temperature sensing devices, but because they are only limited to the contents of the induction cooker, it is still impossible to accurately prevent the overflow of the liquid in the pot set on the induction cooker, and can only measure the temperature roughly. Control, but this kind of rough temperature control still cannot guarantee that the liquid in the pot will not overflow when the user is away, and there is a safety hazard of improper use of the induction cooker
