Fire control method and device of stove, stove and storage medium

The embodiment of the invention provides a fire control method and device of a stove, the stove and a storage medium, and the method comprises the following steps: obtaining a menu, and cooking according to the menu; detecting the temperature value of the bottom of the cooker in the cooking process through a temperature sensor, and determining a temperature change curve according to the temperature value; when a first temperature inflection point appears in the temperature change curve, an inner ring proportional valve is controlled to be closed, so that an inner ring fire distributor stops outputting fire power; the first temperature inflection point is an inflection point at which the temperature change curve is converted from a convex curve to a concave curve; when a second temperature inflection point appears in the temperature change curve, the inner ring proportional valve is controlled to be opened, and the fire output gear of the inner ring fire distributor is adjusted; the second temperature inflecti
