Method of accurately measuring temperature of food in cookware on gas stove

Abstract

The invention relates to a method of accurately measuring the temperature of food in cookware on a gas stove, which is characterized in that an infrared temperature measurement module is installed onthe rear wall surface of a stove or on a range hood above the stove; the infrared temperature measurement module comprises a distance sensor and an infrared temperature measurement sensor which are rotatably arranged, and a controller electrically connected with the distance sensor and the infrared temperature measurement sensor, and a pre-stored data table when no cookware is placed on the stoveis pre-stored in the controller; when the cookware is placed on a combustor of the stove, after the combustor is ignited, the controller finds any three points on the edge of the upper end of the cookware, and the diameter, the height and the central point position of the cookware are determined through any three points on the edge of the upper end of the cookware; then, the infrared temperature measurement sensor is rotated, so that the infrared temperature measurement sensor obtains the temperature of the food at different points in the cookware according to a preset line. Compared with theprior art, the method disclosed in the invention has the advantages that the cost is low, the structure of the combustor does not need to be changed, and the temperature of food in cookware on the gasstove can be accurately measured.

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] The existing food temperature measurement methods in the gas stove pot 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-t...

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.
