How does the overheat protection function of the smart air fryer work

In the wide application of modern kitchen appliances, smart air fryers have gradually become a popular choice for consumers with their efficient, convenient and healthy cooking characteristics. However, while enjoying the convenience brought by this innovative device, safety issues cannot be ignored. To ensure the safety of the device during long-term operation or abnormal conditions, the smart air fryer has built-in multiple safety protection mechanisms, among which the overheat protection function is particularly critical.
The overheat protection function is the core of the safety design of the smart air fryer. Its main function is that when the temperature inside the device rises abnormally and exceeds the preset safety range, the system can respond quickly, automatically cut off the power supply or adjust the working state, thereby effectively preventing safety accidents such as fire or equipment damage caused by overheating.
The core components of this function include temperature sensors and overheat protectors (also called thermistors or temperature control switches). The temperature sensor is usually installed near the heating element of the air fryer or in the cooking cavity, responsible for real-time monitoring of the temperature inside the device. When the temperature reaches the set safety threshold, the temperature sensor sends a signal to the control system to trigger the overheat protection mechanism.
As an electrical safety device, the overheat protector is usually connected in series in the power circuit of the device. When the temperature detected by the temperature sensor exceeds the safety threshold, the overheat protector will quickly cut off the circuit and power supply to prevent the device from continuing to heat. This process is automated and does not require user intervention, ensuring that the device can quickly stop working under abnormal circumstances to avoid safety accidents.
In the design of the smart air fryer, the overheat protection function is combined with the temperature control system to form a closed-loop safety protection system. The temperature control system monitors the temperature changes in the cooking cavity in real time and automatically adjusts the heating power and time according to the preset cooking program. When the temperature sensor detects an abnormal increase in temperature, the temperature control system will immediately activate the overheat protection mechanism and sound an alarm to remind users to pay attention to safety.
