In the above scheme, for example, the control device may adjust the flow rate of the gas introduced into the gas cooker according to the parameters in each group of instruction parameter arrays in the preset instruction set, so as to implement automatic cooking, and at the same time, in step S112, the temperature of the cooker is detected, and PID adjustment is performed using the temperature of the cooker as a closed-loop control parameter, so as to accurately adjust the flow rate of the gas introduced into the gas cooker, thereby implementing accurate and intelligent automatic cooking.

As an example, during the cooking time, a timer is started, the opening degree of a flow valve is adjusted to a set fire lower case, meanwhile, a detection device, namely a pot bottom temperature sensor arranged at the bottom of a cooker detects the temperature of the cooker, the detected temperature of the cooker is compared with a set cooking temperature, and when the set cooking temperature is exceeded or a set cooking temperature is exceeded for a certain range, for example, 4 ℃, the flow of gas introduced into the gas stove is adjusted to be reduced; on the contrary, reference is made in detail to the above-mentioned related exemplary description of gas cookers. After the cooking parameters of each stage are executed and the end condition is reached, the timer is reset, the gas introduced into the gas stove is adjusted to be closed, the alarm and the display prompt are carried out, the automatic cooking is finished, and one-key cooking is realized.

As another example, when a user needs to autonomously set a cooking mode, the user can input cooking parameters of each stage through the control panel, and receive a user instruction and one or more instruction parameter arrays; and associating the user instruction with the one or more instruction parameter arrays, storing the associated user instruction and the one or more instruction parameter arrays, and completing the writing of the cooking mode.

According to the gas stove and the control method for the gas stove, corresponding protection programs/logics are formulated according to different cooking modes, differential protection and fine control of an automatic cooking process are achieved, and the intelligent level and the automatic level of the gas stove are improved.
