Dry burning control method for gas stove

Abstract

The invention discloses a dry burning control method for a gas stove. The dry burning control method for the gas stove comprises the following steps: successively acquiring the temperature of a pot onthe gas stove according to a preset time interval delta t and recording the temperature as TN, wherein N is a positive integer greater than 0; when TN is greater than T0, determining that the pot isin a dry burning state, controlling gas of the gas stop and stopping combustion; when TN is less than T', determining that the pot is not in the dry burning state and maintaining the state of the gasstove; when TN is greater than T' and less than or equal to Tp, calculating a first derivative dTN / dt and a second derivative d2TN / dt2 of the temperature TN, and judging whether dTN / dt and d2TN / dt2 simultaneously meet the following requirements or not: dTN / dt is greater than delta 1, d2TN / dt2 is greater than delta 2, wherein delta 1 is greater than or equal to 0, and delta 2 is greater than or equal to 0; if dTN / dt and d2TN / dt2 simultaneously meet the requirements, determining that the pot is in the dry burning state, controlling the gas of the gas stove and stopping combustion; and if dTN / dtand d2TN / dt2 do simultaneously meet the requirements, determining that the pot is not in the dry burning state and maintaining the state of the gas stove. According to the dry burning control method for the gas stove, dry burning can be judged effectively and timely, and pot burning caused by dry burning is avoided.

Description

technical field [0001] The present invention relates to the technical field of gas stoves, and more specifically, to a method for controlling dry burning of gas stoves. Background technique [0002] When users use gas stoves to cook, cook soup, or perform other cooking actions, they may have to leave the kitchen temporarily due to various emergencies, such as visiting guests, answering the phone, receiving express delivery, etc., and users often forget to turn it off because they leave in a hurry Gas stoves may cause the dishes in the pot to burn and carbonize. More seriously, the pot may be burned through, and the carbonized dishes in the pot are ignited when they come into contact with the fire, causing a fire. Therefore, it is of great significance to add an anti-dry system to the gas stove to avoid the occurrence of the above situation. [0003] However, the anti-dry burning system in the related art cannot effectively and accurately realize the detection of the dry bu...

AI Technical Summary

Problems solved by technology

[0003] However, the anti-dry burning system in the related art cannot effectively and accurately realize the detection of the dry burning state, and some false detections often occur. The dish cannot be cooked; another example, when it has reached the dry state, it has not yet been judged as dry state, resulting in the dish being burnt or the pot body being burnt
