6. Cooking heating control device of a hob according to claim 5, characterised in that the controller is further adapted to:
when the heating time is greater than or equal to a third preset time, calculating a second temperature difference value, wherein the second temperature difference value is the temperature difference value between the current pot bottom temperature and the last pot bottom temperature; when the second temperature difference value is larger than a preset temperature difference value, returning to the step of controlling the valve to be opened and the ignition device to ignite to heat the cooker, and timing the heating time; and when the second temperature difference value is smaller than or equal to the preset temperature difference value, updating the temperature of the water in the pot represented by the pot bottom temperature detected this time to the boiling point temperature of the water.
7. Cooking heating control device of a hob according to claim 6, characterised in that the controller is further adapted to:
when the second temperature difference value is smaller than or equal to the preset temperature difference value, recording the cumulative frequency of the second temperature difference value reaching the preset temperature difference value and adding one; when the accumulated times are less than the preset times, returning to the step of controlling the valve to be opened and the ignition device to ignite to heat the cooker, and timing the heating time; and after the accumulated times reach preset times, updating the temperature of the water in the pot represented by the pot bottom temperature detected this time to the boiling point temperature of the water.
8. Cooking heating control device of a hob according to claim 6 or 7, characterised in that the controller is further adapted to:
searching a preset fire value corresponding to the updated boiling point temperature of the water in a comparison table of a plurality of preset boiling point temperature ranges and preset fire values of the kitchen range; and adjusting the valve opening of the stove to the valve opening of the stove represented by the preset fire value.
9. A hob, characterized in that it comprises:
a gas supply duct;
a valve mounted on the gas supply duct;
the ignition device is used for igniting the fuel gas sprayed out of the gas supply pipeline;
the pot rack is used for placing a pot;
a cooking heating control device of a cooker as claimed in any one of the claims 5 to 8.
10. A computer storage medium, characterized in that instructions are stored in the computer storage medium, and when the instructions are executed, the instructions realize the cooking heating control method of the cooking range of any one of the claims 1-4.
