[0002] As a new type of electric heating equipment, ceramic stoves have been widely used in home kitchens and commercial kitchens due to their high efficiency, environmental protection, and safety. The working principle of ceramic stoves is mainly to convert electrical energy into thermal energy through internal heating elements (such as heating wires, ceramic heating plates, etc.) to heat cooking utensils or ingredients. However, during the use of ceramic stoves, due to improper operation, external environmental influences, or design defects of the equipment itself, the temperature of the ceramic stove may be too high, which may lead to safety hazards such as equipment damage and fire.

[0003] In order to ensure the safe operation of electric ceramic stoves, most existing electric ceramic stove products are equipped with temperature protection mechanisms. These mechanisms are usually based on temperature sensors such as thermistors or thermocouples at the hardware level. When the temperature of the electric ceramic stove is detected to be too high, the power supply is automatically cut off through the hardware circuit to achieve temperature protection. However, this hardware-based temperature protection method has the problems of slow response speed and poor flexibility, and once the hardware protection circuit fails, it will be difficult to effectively prevent overheating accidents.

[0104] It can be seen that in this optional embodiment, the control submodule can generate a specific heating control instruction according to the heating temperature or power output requirements of the electric ceramic stove, and the heating control instruction can accurately guide the actions of the switch module and the operation control module, thereby realizing accurate temperature or power control of the heating module; this design enables the electric ceramic stove to respond to the user's usage requirements more accurately and improve the user experience. In addition, at least two response mechanisms for user usage requirements are set, specifically temperature control and power control, so that the user can issue instructions according to actual usage requirements, and the corresponding electric ceramic stove equipment can also flexibly adjust the issued instructions, thereby accurately responding to user needs, which is conducive to improving the flexibility of the overall circuit.

[0105] In this optional embodiment, the control submodule 1021 controls the operation control module 103 to execute state switching according to the instruction type of the heating control instruction, specifically including:

[0106] When the instruction type is the temperature control type, and when the heating module 104 is initially heated, the operation control module 103 is controlled to be continuously turned on according to the heating control instruction until it is detected that the module temperature of the heating module 104 reaches the first temperature, and then the operation control module 103 is controlled to be turned off;

[0107] Also, during the continuous operation of the electric ceramic stove, when it is detected that the module temperature drops from the first temperature to the second temperature, the operation control module 103 is switched on according to the heating control instruction; and after it is detected that the module temperature reaches the first temperature, the operation control module 103 is controlled to be disconnected.

[0108] In this optional embodiment, specifically, it is assumed that the working demand temperature issued to the electric ceramic stove is 300°C; when the heating module 104 is initially heated, the switch module 101 is controlled to be permanently turned on, and the operation control module 103 is controlled to be continuously turned on through the heating control instruction until it is detected that the temperature of the heating module 104 is heated to 300°C, and the operation control module 103 is controlled to be turned off; during this period, if it is detected that the temperature of the heating module 104 is lower than the set second temperature, such as 280°C, the operation control module 103 is controlled to be turned on again to heat the temperature of the heating module 104 back to 300°C.

[0109] It can be seen that in this optional embodiment, in the temperature control mode, the temperature of the heating module is monitored in real time, and the power supply is cut off in time when the set temperature (first temperature) is reached to prevent overheating; when the temperature drops to another set value (second temperature), the power supply is turned on again to ensure that the temperature of the stove plate is stable within the range expected by the user. This intelligent temperature adjustment method not only improves the accuracy of temperature control, but also enhances the stability and safety of the circuit.

[0110] Optionally, the control submodule 1021 controls the operation control module 103 to execute state switching according to the instruction type of the heating control instruction, and specifically includes:

[0111] When the instruction type is a power control type, the target output power for the furnace plate and the rated output power of the furnace plate are determined according to the heating control instruction;

[0112] Determine the module on time ratio and the module off time ratio for the operation control module 103 according to the target output power and the rated output power;

[0113] According to the module on-time ratio and the module off-time ratio, the operation control module 103 is subjected to on-off control.

[0114] In this optional embodiment, specifically, it is assumed that the working power demanded by the electric ceramic stove is 400W; and the rated output power of the electric ceramic stove is 1000W; correspondingly, when controlling the heating of the electric ceramic stove, the switch module 101 is controlled to be permanently turned on, and the operation control module 103 is controlled to switch between on and off according to the ratio of module on time: module off time = 6:4, so that the average output power of the electric ceramic stove reaches 400W.

[0115] It can be seen that in this optional embodiment, in the power control mode, the control submodule can calculate the proportion of the on and off time of the operation control module according to the ratio of the target output power to the rated output power, thereby realizing the precise adjustment of the output power of the stove plate. This control method enables the electric ceramic stove to provide appropriate power output according to different cooking needs, improves the accuracy of power output, and is conducive to improving the safety of power output while reducing energy waste.

[0116] In yet another optional embodiment, Figure 2 As shown, the software control module 102 also includes a temperature detection submodule 1022, wherein:

[0117] The third end of the control submodule 1021 is electrically connected to the first end of the temperature detection submodule 1022; the second end of the temperature detection submodule 1022 is electrically connected to the first end of the heating module 104;

[0118] The temperature detection submodule 1022 is used to detect the module temperature of the heating module 104 in real time and feed back the module temperature to the control submodule 1021;

[0119] The control submodule 1021 is further used to analyze the module temperature, and when it is determined that the module temperature is higher than the set safety temperature, generate a first protection instruction, and control the operation control module 103 to disconnect according to the first protection instruction.

[0120] In this optional embodiment, the temperature detection submodule 1022 can specifically be a thermocouple, and the thermocouple can be set to 1-12 groups according to actual usage requirements; the function of the thermocouple is to detect the module temperature of the target module (such as a heating module) and feed back the corresponding module temperature to the software control module 102.

[0121] In this optional embodiment, the control submodule 1021 is further used to generate a second protection instruction after the operation control module 103 is disconnected according to the first protection instruction, and when the module temperature continuously fed back by the temperature detection submodule 1022 is detected, and control the switch module 101 to disconnect according to the second protection instruction;

[0122] The control submodule 1021 is also used to generate a third protection instruction after controlling the switch module 101 to disconnect according to the second protection instruction and when the module temperature continuously fed back by the temperature detection submodule 1022 is detected, and control the mechanical temperature control protection module 105 to disconnect according to the third protection instruction.

[0123] In this optional embodiment, when the module temperature of the heating module is higher than the set safety temperature, the control submodule first generates a first protection instruction to control the operation control module to disconnect so as to cut off the power supply of the heating module to prevent the temperature from continuing to rise; if the temperature detection submodule continues to feedback high temperature after the operation control module is disconnected, it is assumed that there is a fault in the operation control module at this time, and the control submodule generates a second protection instruction to control the switch module to disconnect, and cut off the power supply of the entire circuit at the control level corresponding to the upper management level of the operation control module to ensure that the internal part will not be damaged due to overheating; if the above two layers of protection measures still fail to reduce the temperature, the control submodule will generate a third protection instruction to control the mechanical temperature control protection module to disconnect, which involves the outermost layer (highest management level) protection mechanism to maximize the protection of circuit safety.

[0124] It can be seen that in this optional embodiment, the temperature detection submodule can detect the temperature of the heating module in real time and feed the data back to the control submodule. This real-time monitoring mechanism is conducive to the circuit's detection speed of abnormal temperature conditions; further, through a multi-level, gradually upgraded temperature protection system, it can significantly reduce the risk of damage to the circuit or the device corresponding to the circuit due to overheating, and improve the safety and reliability of the circuit or the device corresponding to the circuit.

[0127] like Figure 1 As shown, the temperature protection and safety protection method applied to the electric ceramic stove may include the following operations:

[0128] 201. The software control module generates a heating control instruction according to the detected usage demand for the electric ceramic stove, and performs heating control on the target operation module according to the heating control instruction.

[0129] In the embodiment of the present invention, the target operation module includes a switch module, an operation control module and a heating module.

[0130] 202. The software control module detects the operating temperature data of the electric ceramic stove in real time, and when it is determined that the operating temperature data meets a preset first temperature protection condition, generates a first temperature control instruction, and executes a first temperature control operation matching the first temperature control instruction.

[0131] In the embodiment of the present invention, the first temperature management and control operation includes disconnection control for the operation control module and / or shutdown control for the switch module.

[0132] It can be seen that implementation Figure 3 The described temperature protection and safety protection circuit applied to the electric ceramic stove can intelligently generate a heating control instruction according to the detected use requirements of the electric ceramic stove (such as the temperature and power set by the user) through the software control module, and perform precise heating control on the target operation module (including the switch module, the operation control module and the heating module). This intelligent control mechanism ensures that the electric ceramic stove can operate stably under the conditions expected by the user, improves the heating efficiency and the user's experience of the electric ceramic stove; further, the software control module also has the function of real-time detection of the operation temperature data of the electric ceramic stove. When it is detected that the operation temperature data meets the preset first temperature protection condition (such as too high temperature, abnormal temperature change, etc.), the module can quickly generate a first temperature control instruction and execute a first temperature control operation matching the instruction (such as disconnecting the operation control module or turning off the switch module). This real-time temperature monitoring and rapid response mechanism effectively prevents safety hazards caused by overheating and ensures the safe operation of the system; in addition, the software control module is linked to the switch module, or the software control module is linked to the operation control module. The dual temperature protection mechanism enables the other temperature protection mechanism to be stably executed when a certain temperature protection mechanism fails, further improving the practicality and safety of the overall circuit.

[0135] The above-mentioned method in which the software control module generates a heating control instruction according to the detected usage requirements for the electric ceramic stove, and performs heating control on the target operation module according to the heating control instruction specifically includes:

[0136] The control submodule generates a heating control instruction according to the detected usage requirements for the electric ceramic stove, and controls the switch module to switch to a closed state according to the heating control instruction. At the same time, the operation control module is controlled to perform state switching according to the instruction type of the heating control instruction. The instruction type includes a temperature control type or a power control type; the state switching includes switching of the module on or off.

[0137] In this optional embodiment, when the instruction type is a temperature control type, the usage requirement includes a heating temperature requirement for the stove plate in the electric ceramic stove; the heating control instruction includes at least a first temperature and a second temperature corresponding to the heating temperature requirement; when the instruction type is a power control type, the usage requirement includes a power output requirement for the stove plate in the electric ceramic stove.

[0138] It can be seen that in this optional embodiment, the control submodule can generate a specific heating control instruction according to the heating temperature or power output requirements of the electric ceramic stove, and the heating control instruction can accurately guide the actions of the switch module and the operation control module, thereby realizing accurate temperature or power control of the heating module; this design enables the electric ceramic stove to respond to the user's usage requirements more accurately and improve the user experience. In addition, at least two response mechanisms for user usage requirements are set, specifically temperature control and power control, so that the user can issue instructions according to actual usage requirements, and the corresponding electric ceramic stove equipment can also flexibly adjust the issued instructions, thereby accurately responding to user needs, which is conducive to improving the flexibility of the overall circuit.

[0139] In this optional embodiment, the above-mentioned manner in which the control submodule controls the operation control module to execute state switching according to the instruction type of the heating control instruction specifically includes:

[0140] When the instruction type is the temperature control type, and when the heating module is initially heated, the control submodule controls the operation control module to be continuously turned on according to the heating control instruction, and controls the operation control module to be turned off after detecting that the module temperature of the heating module reaches the first temperature;

[0141] Also, during the continuous operation of the electric ceramic stove, when it is detected that the module temperature drops from the first temperature to the second temperature, the control submodule switches the operation control module to on according to the heating control instruction; and after it is detected that the module temperature reaches the first temperature, the operation control module is controlled to be off.

[0142] In the temperature control mode, the temperature of the heating module is monitored in real time, and the power supply is cut off in time when the set temperature (first temperature) is reached to prevent overheating; when the temperature drops to another set value (second temperature), the power supply is turned on again to ensure that the temperature of the furnace plate is stable within the range expected by the user. This intelligent temperature adjustment method not only improves the accuracy of temperature control, but also enhances the stability and safety of the circuit.

[0143] Optionally, the above-mentioned method of controlling the operation control module by the control submodule to execute state switching according to the instruction type of the heating control instruction specifically includes:

[0144] When the instruction type is a power control type, the control submodule determines the target output power for the furnace plate and the rated output power of the furnace plate according to the heating control instruction;

The second temperature control operation includes shutdown control for the mechanical temperature control protection module.

[0155] It can be seen that implementation Figure 4 The temperature protection and safety protection circuit described for electric ceramic stoves adds a physical layer of temperature protection measures on the basis of the above temperature protection scheme, that is, a triple temperature protection mechanism is set up. This multi-level design can more effectively cope with different levels of overheating, so that even if the first two layers of temperature protection mechanisms fail, there is still a last layer of physical layer of minimum temperature protection mechanism, which further improves the reliability and safety of the overall circuit.
