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.

The utility model discloses embodiment's gas-cooker and be used for control method of gas-cooker sets up flow control system, carries out automatically regulated according to the flow of presetting the instruction set to the gas of flowing through the gas pipeline, accomplishes the regulation of gas flow automatically, realizes automatic culinary art process, improves the intelligent level and the automation level of gas-cooker.

The related exemplary description of the control method for the gas stove of the above scheme refers to the related exemplary description in the gas stove of fig. 1-2, which is not repeated herein.
