A method for accurately measuring the temperature of food in a pot on a gas stove

Abstract

The invention relates to a method for accurately measuring the temperature of food in a cooker on a gas cooker, which is characterized in that an infrared temperature measurement module is installed on the wall behind the cooker or on a range hood above the cooker, and the infrared temperature measurement module includes a rotating distance sensor, infrared temperature sensor, and a controller electrically connected to the distance sensor and the infrared temperature sensor, and the pre-stored data table when there is no pot on the cooker is stored in the controller; when the cooker is placed on the burner of the cooker, Above, after the burner is ignited, the controller finds any three points on the upper edge of the pot, and determines the diameter, height and center point of the pot through any three points on the upper edge of the pot; then, turn the infrared temperature measurement The sensor enables the infrared temperature measuring sensor to obtain the temperature of food at different points inside the pot according to a predetermined circuit. Compared with the prior art, the invention has the advantages of low cost, no need to change the structure of the burner, and the ability to accurately measure the temperature of food in the pan on the gas stove.

Description

technical field [0001] The invention relates to a method for accurately measuring the temperature of food in a pot on a gas stove. Background technique [0002] As users have higher and higher requirements for cooking experience, intelligent control and cooking safety, how to accurately measure the temperature of food in the pot, further prevent food from drying out, and realize the intelligent reminder function of intelligent recipes is an important issue now. research direction. [0003] Existing methods for measuring the temperature of food in gas stoves mainly include: NTC temperature measurement at the bottom of the pot, infrared temperature measurement at the bottom of the pot, and temperature measurement in the form of a probe. [0004] The NTC temperature measurement at the bottom of the pot needs to change the structure of the burner and open holes in the inner ring, which will easily lead to uneven temperature at the bottom of the pot; the interference of high-tem...

AI Technical Summary

Problems solved by technology

[0004] The NTC temperature measurement at the bottom of the pot needs to change the structure of the burner and open holes in the inner ring, which will easily lead to uneven temperature at the bottom of the pot; the interference of high-temperature flue gas and flame in the inner ring will also affect the temperature measurement accuracy; and the adaptability of the pot is poor. If the bottom of the pot is concave, the ceramic pot will affect the temperature measurement accuracy; the infrared temperature measurement of the bottom of the pot still needs to be in contact with the bottom of the pot, and the structure of the burner also needs to be changed, and the inner ring of the burner needs to be opened, and the lens is easily affected by oil pollution.
