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

Abstract

The invention provides a liquid overflowing detection method and device, a pot and an electromagnetic heating assembly. The liquid overflowing detection method comprises the steps of generating a gaspressure signal according to a gas pressure state in a container in the process of heating liquid in the container covered with a cover plate; judging whether or not the liquid is in a state of beingabout to overflow according to the change trend of the gas pressure signal. By means of the liquid overflowing detection method and device, liquid overflowing can be accurately and reliably detected while it is ensured that the liquid in the pot is well cooked, and therefore the liquid in the pot can be effectively prevented 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
