Liquid overflow detection method and device, cooker 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 comprises the following steps of generatingan air flow signal according to the air flow state of air passing a through hole in a cover plate in the process of heating liquid in a container covered with the cover plate; and judging whether theliquid is in a to-be-overflowing state according to the change tendency of the air flow signal. According to the method and device, overflow of liquid can be accurately and reliably detected while the liquid in the cooker is cooked, and then the liquid in the cooker can be effectively prevented from overflowing.

Description

Technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a liquid overflow detection method and device, pots and pans, and electromagnetic heating components. Background technique [0002] With the rapid development of social economy and technology, time has become the most valuable asset for people, and cooking, as a necessary life foundation that is inaccessible to humans, requires a certain amount of time. Therefore, cooking efficiency has become a demand for people. And the focus of attention, especially liquid foods such as porridge or soup. 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 several minutes to ten to twenty minutes to boil the soup. During the whole process of cooking porridge or soup, users need to go to the induction cooker ...

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
