[0117] Resistor R12 (3KΩ) is a basic component in the circuit and is used to limit the current. In this low power consumption subcircuit 50, R12 is used for voltage division, current limiting or as a working point setting for other components. 3KΩ means that its resistance is 3 kilo ohms.

[0118] Transistor Q1 (8050): 8050 is a commonly used NPN silicon transistor with amplification and switching functions. In this low power subcircuit 50, Q1 is used for signal amplification, switch control or as part of a relay drive circuit.

[0119] Relay RY1 (3KΩ, RELAY1) is an automatic switch that can control a large current with a small current. In this low-power subcircuit 50, the coil resistance of RY1 is 3KΩ, which means that the power consumed by its coil is low, which helps to achieve low power consumption.

[0126] The first end of the electric ceramic stove circuit 20 is electrically connected to the first end of the first protection module 401; the second end of the first protection module 401 and the first end of the second protection module 402 are both used to connect to the positive electrode of the external power supply; the second end of the second protection module 402 is electrically connected to the first end of the induction cooker circuit 10;

[0127] The first protection module 401 is used to detect a first current value corresponding to a first current flowing through the first protection module 401, and when it is determined that the first current value is higher than a first rated current value, perform a fuse control on the first protection module 401 to cut off the connection circuit between the first protection module 401 and the electric ceramic stove sub-circuit 20;

[0128] The second protection module 402 is used to detect a second current value corresponding to a second current flowing through the second protection module 402, and when it is determined that the second current value is higher than the second rated current value, perform fuse control on the second protection module 402 to cut off the connection circuit between the second protection module 402 and the induction cooker sub-circuit 10.

[0129] In this optional embodiment, by setting up the first and second protection modules, real-time monitoring of the current flowing through is achieved, and when the current flowing through exceeds the rated current value, fuse control is automatically executed to cut off the connection circuit between the protection module and other circuits connected to it (such as the connection circuit between the first protection module and the electric ceramic stove circuit), thereby preventing safety hazards such as overheating, damage and even fire caused by excessive current.

[0130] In this optional embodiment, specifically, the first protection module 401 and the second protection module 402 may be conventional fuses.

[0131] It can be seen that in this optional embodiment, by designing the protection sub-circuit to include the first protection module and the second protection module, dual protection of the electric ceramic stove sub-circuit and the induction cooker sub-circuit is achieved. This design not only enhances the safety of the intelligent control circuit, but also helps to improve the stability, reliability and practicality of the intelligent control circuit.

[0132] In yet another optional embodiment, Figure 2 As shown, the protection subcircuit 40 further includes a zero-crossing detection module 403, wherein:

[0134] The zero-crossing detection module 403 is used to perform at least one operation of detection, isolation and transmission on the zero-crossing signal of the intelligent control circuit, and perform zero-crossing protection on the intelligent control circuit according to the zero-crossing signal.

[0135] See also Figure 8 , Figure 8 1 is a schematic diagram of the structure of a zero-crossing detection module in an intelligent control circuit integrating an induction cooker and an electric ceramic cooker disclosed in an embodiment of the present invention; Figure 8 As shown, the zero-crossing detection module 403 includes a resistor R5 (10K), a diode D1 (M7), a capacitor U5 (200K / 0.5w), a resistor R1 (200K / 0.5w) and an optocoupler isolator (OPTOISO1, U5), wherein:

[0136] Resistor R5 (10K) is used as a current limiting resistor to limit the current flowing into the subsequent circuit and protect the circuit components from being damaged by excessive current.

[0137] The diode D1 (M7) is used as a half-wave rectifier or a signal detector. In the zero-crossing detection module 403, it is used to convert the AC signal into a DC signal, or to allow only the positive half cycle (or negative half cycle) of the signal to pass. Usually in zero-crossing detection, the diode is used to detect the zero-crossing point of the signal, because when the signal passes through the zero point, the conduction state of the diode changes.

[0138] ZERO Zero-crossing signal: This is the detection target of the zero-crossing detection module 403, which is usually an AC voltage or overcurrent signal extracted from an AC power supply. This signal passes through the zero point twice in each AC cycle.

[0139] Resistor R1 (200K / 0.5w), as a current limiting resistor, is similar to R5 and is used to limit the current flowing into the subsequent circuit.

[0140] Optocoupler isolator (OPTOISO1, U5), an optical coupler isolator is a component that completely isolates the input circuit from the output circuit electrically, and is usually used to eliminate the ground potential difference between circuits or to achieve isolated signal transmission. In the zero-crossing detection module 403, the optical coupler isolator can be used to isolate the detected zero-crossing signal from the main circuit to protect the main circuit from interference or damage.

[0141] In this optional embodiment, the zero-crossing detection module can monitor the voltage waveform of the intelligent control circuit in real time and accurately capture the voltage zero-crossing point, that is, the moment when the voltage passes through the zero point when changing from positive to negative or from negative to positive. This function is crucial for circuit protection, because the zero-crossing point is usually the safest switching moment in the circuit, which can avoid switching the circuit state at the voltage peak, thereby reducing arc generation and contact wear, and extending the service life of the circuit.

[0142] In this optional embodiment, the zero-crossing detection module also has an isolation function, which can ensure that the detected zero-crossing signal is not interfered by other circuits, thereby ensuring the accuracy and reliability of the signal. This feature is particularly important for signal transmission in complex circuit systems, and can avoid misoperation or protection failure caused by signal distortion or interference.

[0143] More importantly, the zero-crossing detection module can perform zero-crossing protection on the intelligent control circuit according to the detected zero-crossing signal. This means that when an abnormality or fault occurs in the circuit, the zero-crossing detection module can respond quickly and safely cut off or adjust the circuit state near the voltage zero-crossing point, thereby effectively preventing circuit damage or equipment failure caused by sudden power failure or abnormal switching.

[0144] It can be seen that in this optional embodiment, by introducing a zero-crossing detection module in the protection sub-circuit, not only the accurate detection, effective isolation and reliable transmission of the zero-crossing signal of the intelligent control circuit are achieved, but also the zero-crossing protection strategy is executed based on these zero-crossing signals, thereby greatly improving the overall performance of the circuit system and further improving the practicability and safety of the intelligent control circuit.
