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 heating process of the liquid in a container covered with a cover plate, generating air pressure according to the air pressure state in the container signal; judging whether the liquid is in a state to be overflowed according to the change trend of the air pressure signal. The invention can accurately and reliably detect the overflow of the liquid while ensuring that the liquid in the pot is cooked, thereby effectively preventing the liquid in the pot from overflowing.

Description

Technical field [0001] Technical Field The present invention relates to a kitchen appliance, particularly relates to a liquid heating assembly electromagnetic spill detection method and apparatus, pots and pans. Background technique [0002] With the rapid development of social economy and science and technology, the time for the people has become the most valuable asset, and cooking as a necessary foundation of human life can not be obtained but need to pay a certain period of time, and therefore, cooking efficiency has become the people's needs and focus, in particular, soups and other liquid foods or soup, which. Induction of high-power characteristics make it become the first choice for people such as porridge or soup. However, the process of porridge or soup with cooker, although relatively fast, it still takes a few minutes to fifteen or twenty minutes to boil the soup, porridge or soup in the whole process, users need to go to the front of the cooker look there is no soup ...

AI Technical Summary

Problems solved by technology

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
