Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0020] In addition, the technical features involved in the different embodiments of the present invention described later can be combined with each other as long as they do not conflict with each other.
[0021] See also Figure 1-2 In an embodiment of the utility model, an electric flame stove heating device includes: a plasma combustion module, a detection module, a feedback module, and a processing module;
[0022] In the embodiment of the utility model, the plasma combustion module includes a plurality of plasma heaters, and the plasma heaters generate plasma by arc discharge. The plasma has an extremely high temperature and can quickly heat the wok;
[0023] like Figure 1 As shown, implementation mode 1 includes:
[0024] S101: The detection module obtains the temperature of each area of the wok, wherein each plasma heater corresponds to each area of the wok.
[0025] Specifically, the detection module is used to monitor the temperature of each area on the wok during cooking. The detection module obtains the temperature change data of each area of the wok in real time through an infrared temperature sensor arranged above the wok, and transmits the monitored temperature data to the feedback module. The transmission method can be wireless transmission or wired transmission; each area on the wok corresponds to a plurality of plasma heaters respectively;
[0026] S102: The feedback module determines whether there is an unevenly heated area based on whether the difference between the temperature of each area and the average temperature is outside a preset range;
[0027] As a specific implementation method, the feedback module calculates the average temperature value of all areas through an algorithm based on the collected temperature data of all areas. This average temperature value represents the overall heating condition of the wok.
[0028] The following scheme can be used to identify whether there are areas of uneven heating in the wok: the difference between the temperature of each area of the wok and the average temperature is calculated separately. When the difference between the temperature of any area and the average temperature exceeds a preset range, the area is identified as an area of uneven heating.
[0029] S103: The processing module executes instructions to adjust the power of a single plasma heater corresponding to the unevenly heated area.
[0030] As a further implementation method, in order to prevent burning and scorching during cooking, the processing module receives the monitoring results transmitted by the feedback module and regulates the power of the single plasma heater corresponding to the unevenly heated area; when the temperature in any area is too low, the processing module will increase the power of the plasma heater corresponding to the area to raise its temperature to the average temperature value, thereby preventing the dishes in the area from being "difficult to cook" and ensuring that the food can be heated evenly; when the temperature in any area is too high, the processing module will reduce the power of the plasma heater corresponding to the area to ensure that the temperature drops to the average temperature value and avoid burning and scorching that may occur during the cooking process.
[0031] The processing module usually includes a memory and a processor, wherein the memory and the processor are connected by wires or other means, the memory stores data, instructions and calculation results, and the processor regulates the power of a single plasma heater by executing instructions so that each area of the wok is heated evenly.
[0032] like Figure 2 As shown, the second implementation mode includes:
[0033] S201: The detection module obtains the temperature data of each area of the wok and transmits it to the feedback module;
[0034] S202: The feedback module determines whether the pot is in a "dry-burnt" state according to whether the average temperature exceeds a preset maximum temperature value;
[0035] Specifically, the memory presets a maximum temperature value, and when the average temperature of each area of the wok exceeds the maximum temperature value, it is determined to be a "burnt dry pot" state. Usually, the wok is directly heated and burns dry because the water in the wok has evaporated.
[0036] S203: After receiving the "dry pot" information, the processing module immediately initiates the emergency shutdown command to stop the power input of the plasma combustion module;
[0037] Specifically, in order to prevent the food from being burnt or scorched during cooking, the feedback module transmits the "burnt pot" information to the processing module. After receiving the feedback information, the processor immediately executes the instructions preset in the memory to reduce or completely cut off the power input of the plasma combustion module. After the processor executes the above instructions, the system enters a standby state, waiting for user intervention. More specifically, an emergency shutdown instruction is preset in the memory. When the "burnt pot" information is received by the processing module, the emergency shutdown instruction in the memory is immediately activated. After receiving the emergency shutdown instruction in the memory, the processor immediately starts the execution program to stop the control system from outputting power to the plasma combustion module.
[0038] An independent high-voltage rectifier circuit is arranged between a single plasma heater and the processor, and the processor can adjust the power output parameters of the high-voltage rectifier circuit.
[0039] The processor adjusts the density of the ionized gas by regulating the power of the plasma heater corresponding to the non-uniformly heated area, thereby changing the heating parameters of the plasma heater.
[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
