[0002] Currently, most cookware on the market is made of metal or ceramic and requires manual control. During cooking, the cookware, stove, and range hood are operated separately, which is overly complicated for users lacking cooking experience. Traditional stoves on the market control temperature through heat, resulting in imprecise control. This can lead to insufficient preservation of the deliciousness and nutrition of food cooked in traditional cookware, as well as problems such as high electricity and water consumption and environmental pollution. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a gas-electromagnetic dual-mode stove and its control system based on adaptive thermal field reconstruction; it can solve the problem that the control of traditional stoves on the market is not precise enough because they control the stove temperature by heat.

[0004] Technical solution: To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, a gas-electromagnetic dual-mode stove control system based on adaptive thermal field reconstruction, the system includes: a human-machine interaction module, an adaptive adjustment module, a data acquisition module, a data storage module, a core processing module, and an early warning module;

[0005] Human-computer interaction module: used to set stove operating parameters and display the thermal field reconstruction efficiency index and stove operating stability index;

[0006] Adaptive adjustment module: Used to adjust the stove according to the parameters set by the human-computer interaction module, and to determine whether the stove needs to be reconstructed to improve the heating effect based on the thermal field reconstruction efficiency index and the threshold of the thermal field reconstruction efficiency index.

[0007] Data acquisition module: used to collect the required data and transmit the collected data to the data storage module and the core processing module;

[0008] Data storage module: Used for storing and managing various types of data;

[0009] The core processing module is used to calculate the thermal field reconstruction efficiency index based on the average temperature of the heating area, the effective heat absorbed by the cookware, the total energy consumption of gas and electromagnetic heating, the preset theoretical minimum time to reach the target temperature, and the actual time to reach the target temperature. It calculates the stove stable operation index based on the thermal field reconstruction efficiency index, the preset thermal field reconstruction efficiency index threshold, the number of times the thermal field reconstruction efficiency index is lower than the thermal field reconstruction efficiency index threshold, the preset upper limit of the number of times the thermal field reconstruction efficiency index does not exceed the thermal field reconstruction efficiency index threshold, and the value of each thermal field reconstruction efficiency index not exceeding the thermal field reconstruction efficiency index threshold. It then compares the stove stable operation index with the stove operation stability index threshold set by the human-computer interaction module.

[0010] Early warning and reminder module: Based on the comparison result between the stove stable operation index and the threshold of the stove stable operation index, it determines whether to issue an early warning and reminder to the user through the human-computer interaction module to perform maintenance.

[0011] The core processing module obtains the average temperature of the heating area, the effective heat absorbed by the cookware, the total energy consumption of gas and electromagnetic heating, the preset theoretical minimum time to reach the target temperature, and the actual time to reach the target temperature to calculate the thermal field reconstruction efficiency index. First, the heat absorption rate of the cookware is obtained by using the effective heat absorbed by the cookware, the working power of the gas, the working time of the gas, the working power of the electromagnetic heating system, and the working time of the electromagnetic heating system. The proximity to the target temperature is obtained by using the average temperature of the heating area and the preset target temperature. The deviation of the heating efficiency is obtained by using the actual time to reach the target temperature and the preset theoretical minimum time to reach the target temperature. Finally, the heat absorption rate of the cookware, the proximity to the target temperature, and the deviation of the heating efficiency are multiplied together to obtain the thermal field reconstruction efficiency index.

[0012] The core processing module acquires the thermal field reconstruction efficiency index, a preset thermal field reconstruction efficiency index threshold, the number of times the thermal field reconstruction efficiency index is lower than the thermal field reconstruction efficiency index threshold, a preset upper limit for the number of times the thermal field reconstruction efficiency index does not exceed the thermal field reconstruction efficiency index threshold, and calculates the stove stable operation index based on the value of each thermal field reconstruction efficiency index not exceeding the thermal field reconstruction efficiency index threshold.

[0013]

[0014] in, To ensure the stable operation of the stove, This refers to the number of times the thermal field reconstruction efficiency index falls below the threshold of the thermal field reconstruction efficiency index. The upper limit of the number of times the preset thermal field reconstruction efficiency index does not exceed the threshold value of the thermal field reconstruction efficiency index is set. The thermal field reconstruction efficiency index is defined as the thermal field reconstruction efficiency index that falls below the thermal field reconstruction efficiency index threshold each time. The preset threshold for thermal field reconstruction efficiency index. This is the preset index.

[0015] Furthermore, when the human-computer interaction module displays the thermal field reconstruction efficiency index, the effect of thermal field reconstruction can be judged based on the thermal field reconstruction efficiency index. The larger the thermal field reconstruction efficiency index, the better the thermal field reconstruction effect, and vice versa.

[0016] Furthermore, when the core processing module compares the thermal field reconstruction efficiency index with the threshold of the thermal field reconstruction efficiency index to determine whether thermal field reconstruction is needed to improve the heating effect of the stove, if the thermal field reconstruction efficiency index is greater than the threshold of the thermal field reconstruction efficiency index, the current state is maintained and thermal field reconstruction is not performed; otherwise, the stove heating effect is improved by thermal field reconstruction through the adaptive adjustment module.

[0017] Furthermore, when the human-computer interaction module displays the stove's operational stability index, the stove's operating status can be judged by the stove's operational stability index. The higher the stove's operational stability index, the better the stove's operating status, and vice versa.

[0018] Furthermore, the early warning module determines whether to issue a maintenance warning to the user through the human-computer interaction module based on the comparison result between the stove stable operation index and the threshold of the stove stable operation index. When the stove stable operation index is not greater than the threshold of the stove stable operation index, the early warning module issues a maintenance warning to the user through the human-computer interaction module; otherwise, it does not issue a maintenance warning to the user through the human-computer interaction module.

[0019] Furthermore, the threshold of the thermal field reconstruction efficiency index, the upper limit of the number of times the thermal field reconstruction efficiency index does not exceed the threshold of the thermal field reconstruction efficiency index, and the threshold of the stove operation stability index can all be modified according to actual usage needs.

[0020] Furthermore, the data acquisition module collects the average temperature of the heating area and the effective heat absorbed by the cookware through sensors installed in the heating area of ​​the cookware. The total energy consumption of gas and electromagnetic heating is collected through sensors installed in the gas heating area and the electromagnetic heating area, respectively. The actual time to reach the target temperature is obtained through the built-in timer of the control system.

[0021] According to another aspect of the present invention, a gas-electromagnetic dual-mode stove based on adaptive thermal field reconstruction is provided. This stove is used to implement the aforementioned gas-electromagnetic dual-mode stove control system based on adaptive thermal field reconstruction. The stove includes: a stove body; a plurality of casters are provided at the bottom of the stove body; a gas heating device and an electromagnetic heating device are symmetrically arranged on the left and right sides of the top of the stove body; a switch device is symmetrically arranged on the left and right sides of the upper front part of the stove body; a first indicator light is provided on the side of the switch device closest to the middle of the upper front part of the stove body; a second indicator light is provided on the side of the first indicator light furthest from the switch device; and a pot is provided above both the gas heating device and the electromagnetic heating device.

[0022] Beneficial effects: The thermal field reconstruction efficiency index is calculated by taking the average temperature of the heating zone, the effective heat absorbed by the cookware, the total energy consumption of gas and electromagnetic heating, the preset theoretical minimum time to reach the target temperature, and the actual time to reach the target temperature. When the thermal field reconstruction efficiency index is displayed in the human-computer interaction module, the effect of thermal field reconstruction can be judged based on the thermal field reconstruction efficiency index. The higher the thermal field reconstruction efficiency index, the better the thermal field reconstruction effect, and vice versa. The thermal field reconstruction efficiency index is obtained by deriving the thermal field reconstruction efficiency index from multiple data to measure the effect of stove thermal field reconstruction, and the measurement results are more accurate and reliable. When the thermal field reconstruction efficiency index is greater than the threshold of the thermal field reconstruction efficiency index, the current state is maintained and thermal field reconstruction is not performed. Conversely, the adaptive adjustment module performs thermal field reconstruction on the stove to improve the stove heating effect, thereby performing adaptive thermal field reconstruction in a timely manner to ensure the stove cooking effect and avoid the situation where the stove control is inaccurate or untimely due to manual operation, which affects the stove's usage effect. The stove's stable operation index is calculated using the following parameters: the thermal field reconstruction efficiency index, a preset thermal field reconstruction efficiency index threshold, the number of times the thermal field reconstruction efficiency index falls below the threshold, the preset upper limit for the number of times the thermal field reconstruction efficiency index does not exceed the threshold, and the value of each thermal field reconstruction efficiency index not exceeding the threshold. The stove's stable operation index is used to determine its operating status; a higher index indicates better operation, and vice versa. This allows for real-time monitoring of the stove's current operating status. Furthermore, when the stable operation index is not greater than the threshold, a maintenance warning is issued to the user via the human-computer interaction module, ensuring that the user promptly detects any issues with the stove's operation and performs timely maintenance to maintain its effectiveness.

[0026] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0027] First, the stove is started through the human-machine interaction module, and relevant parameters are set during the stove control process. The adaptive control module adjusts the stove according to the parameters set by the human-machine interaction module. The data acquisition module collects various data required during the operation of the stove control system and transmits them to the data storage module and the core processing module. The data storage module stores and manages the various data collected by the data acquisition module.

[0028] Then, the core processing module obtains the average temperature of the heating area, the effective heat absorbed by the cookware, the total energy consumption of gas and electromagnetic heating, the preset theoretical minimum time to reach the target temperature, and the actual time to reach the target temperature from the data acquisition module and data storage module. It calculates the thermal field reconstruction efficiency index and compares the thermal field reconstruction efficiency index with the threshold set by the human-computer interaction module. The human-computer interaction module displays the thermal field reconstruction efficiency index. The adaptive adjustment module determines whether the stove needs thermal field reconstruction to improve the stove's heating effect based on the comparison results of the thermal field reconstruction efficiency index and the threshold set by the core processing module.

[0029] The core processing module obtains the average temperature of the heating area, the effective heat absorbed by the cookware, the total energy consumption of gas and electromagnetic heating, the preset theoretical minimum time to reach the target temperature, and the actual time to reach the target temperature to calculate the thermal field reconstruction efficiency index. First, the heat absorption rate of the cookware is obtained by using the effective heat absorbed by the cookware, the working power of the gas, the working time of the gas, the working power of the electromagnetic heating system, and the working time of the electromagnetic heating system. The proximity to the target temperature is obtained by using the average temperature of the heating area and the preset target temperature. The deviation of the heating efficiency is obtained by using the actual time to reach the target temperature and the preset theoretical minimum time to reach the target temperature. Finally, the heat absorption rate of the cookware, the proximity to the target temperature, and the deviation of the heating efficiency are multiplied together to obtain the thermal field reconstruction efficiency index. The cookware heat absorption rate represents the effective heat absorbed by the cookware per unit of energy consumption, thus measuring energy utilization efficiency. The target temperature proximity rate assesses how close the current temperature is to the target temperature. When the average temperature of the heating area is lower than the preset target temperature, the larger the denominator, the lower the closeness between the current temperature and the target temperature. The heating efficiency deviation rate compares the actual heating speed with the theoretical optimal value. When the actual heating time to the target temperature is greater than the preset theoretical minimum heating time to the target temperature, the larger the denominator, the greater the deviation of the actual heating speed from the theoretical optimal value.

[0030] When the thermal field reconstruction efficiency index is displayed in the human-computer interaction module, the effect of thermal field reconstruction can be judged based on the thermal field reconstruction efficiency index. The larger the thermal field reconstruction efficiency index, the better the thermal field reconstruction effect, and vice versa. Based on the comparison results of the thermal field reconstruction efficiency index and the threshold of the thermal field reconstruction efficiency index by the core processing module, it is determined whether thermal field reconstruction of the stove is needed to improve the stove heating effect. When the thermal field reconstruction efficiency index is greater than the threshold of the thermal field reconstruction efficiency index, the current state is maintained and thermal field reconstruction is not performed. Otherwise, the stove heating effect is improved by thermal field reconstruction through the adaptive adjustment module. The ways to improve the stove heating effect by thermal field reconstruction through the adaptive adjustment module include, but are not limited to: adjusting the gas valve opening and adjusting the power of the electromagnetic coil. After adjusting the gas valve opening and the power of the electromagnetic coil, the adjusted thermal field reconstruction efficiency index is analyzed and processed until the adjusted thermal field reconstruction efficiency index is greater than the threshold of the thermal field reconstruction efficiency index, and then the thermal field reconstruction adjustment of the stove is stopped.

[0031] Finally, the core processing module obtains the thermal field reconstruction efficiency index, the preset thermal field reconstruction efficiency index threshold, the number of times the thermal field reconstruction efficiency index is lower than the threshold, the preset upper limit of the number of times the thermal field reconstruction efficiency index does not exceed the threshold, and the value of each thermal field reconstruction efficiency index not exceeding the threshold from the data acquisition module, data storage module, and human-computer interaction module. It then calculates the stove stable operation index and compares it with the stove operation stability index threshold set by the human-computer interaction module. The human-computer interaction module displays the stove operation stability index, and the early warning module determines whether to issue a maintenance early warning to the user through the human-computer interaction module based on the comparison result between the stove stable operation index and the threshold.

[0032] The core processing module acquires the thermal field reconstruction efficiency index, the preset thermal field reconstruction efficiency index threshold, the number of times the thermal field reconstruction efficiency index is lower than the threshold, the preset upper limit of the number of times the thermal field reconstruction efficiency index does not exceed the threshold, and the value of each thermal field reconstruction efficiency index not exceeding the threshold to calculate the stove's stable operation index.

[0033]

[0034] in, To ensure the stable operation of the stove, This refers to the number of times the thermal field reconstruction efficiency index falls below the threshold of the thermal field reconstruction efficiency index. The upper limit of the number of times the preset thermal field reconstruction efficiency index does not exceed the threshold value of the thermal field reconstruction efficiency index is set. The thermal field reconstruction efficiency index is defined as the thermal field reconstruction efficiency index that falls below the thermal field reconstruction efficiency index threshold each time. The preset threshold for thermal field reconstruction efficiency index. For the preset index, in In the process, when the number of times the thermal field reconstruction efficiency index falls below the threshold is closer to the preset upper limit of the number of times the thermal field reconstruction efficiency index does not exceed the threshold, this item tends to zero, indicating a significant decrease in the stability of stove operation. This is indicated by the index... The negative impact of the number of times the thermal field remodeling efficiency index falls below the threshold on the stove's operational stability was mitigated by... This represents the total deviation of the thermal field reconstruction efficiency index. The larger the total deviation of the thermal field reconstruction efficiency index relative to the preset thermal field reconstruction efficiency index threshold, the better. The smaller the value, the higher the deviation of the thermal field reconstruction efficiency index. The natural exponential function ensures that the higher the deviation of the thermal field reconstruction efficiency index, the lower the stove stable operation index.

[0035] When the human-computer interaction module displays the stove's operational stability index, the stove's operating status can be judged by the index. The higher the index, the better the stove's operating status, and vice versa. When the stove's operational stability index is not greater than the threshold, the human-computer interaction module will issue a maintenance warning to the user; otherwise, it will not. Example

[0036] When calculating the stable operation index of a stove, there are , =0.7, 0.45, then we have:

[0037]

[0038] Then when At that time, a maintenance warning is issued to the user through the human-computer interaction module. At times, maintenance warnings are not sent to users through the human-computer interaction module.

[0039] Furthermore, the threshold values ​​for the thermal field reconstruction efficiency index, the maximum number of times the thermal field reconstruction efficiency index does not exceed the threshold value, and the threshold values ​​for the stove operation stability index can all be modified according to actual usage needs. Example

[0040] The gas-electromagnetic dual-mode stove control system based on adaptive thermal field reconstruction includes: a stove body 1, with multiple casters 2 at the bottom of the stove body 1 for easy movement; a gas heating device 3 and an electromagnetic heating device 4 symmetrically arranged on the left and right sides of the top of the stove body 1; a switch device 5 symmetrically arranged on the left and right sides of the upper front of the stove body 1; a first indicator light 6 located on the side of the switch device 5 closest to the center of the upper front of the stove body 1; and a second indicator light 7 located on the side of the first indicator light 6 furthest from the switch device 5; and a pot 8 located above the gas heating device 3 and the electromagnetic heating device 4, with the pot 8 heated by the cooperation of the gas heating device 3 and the electromagnetic heating device 4.

[0041] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
