Gas stove anti-dry-burning control method and device and gas stove

Abstract

The invention discloses a gas stove anti-dry-burning control method and device and a gas stove. The gas stove anti-dry-burning control method comprises the steps of sequentially acquiring the temperature of a pot body on the gas stove according to preset time intervals, namely delta t, and recording the temperature as TN, wherein N is a positive integer greater than zero; when TN is greater than T0, judging that the pot body reaches the dry-burning state, and controlling gas of the gas stove to stop burning; when TN is less than T', judging that the pot body does not reach the dry-burning state, and maintaining the state o the gas stove; when TN is greater than T' and less than or equal to T0, calculating a first order derivative, namely dTN / dt, and a second order derivative, namely d<2>TN / dt<2>, of the temperature TN, and judging whether dTN / dt and d<2>TN / dt<2> meet the requirements that dTN / dt is greater than delta1 and d<2>TN / dt<2> is greater than delta2 at the same time or not, wherein delta1 is greater than or equal to 0, and delta2 is greater than or equal to 0; if the requirements are met, judging that the pot body reaches the dry-burning state, and controlling the gas of the gas stove to stop burning; and if the requirements are not met, judging that the pot body does not reach the dry-burning state, and maintaining the state of the gas stove. By means of the gas stove anti-dry-burning control method, dry burning can be effectively avoided or stopped.

Description

technical field [0001] The invention relates to the technical field of gas stoves, and more specifically, to a gas stove dry-burn prevention control method, a gas stove dry-burn prevention control device, and a gas stove. 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 effective...

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
