How does the overheating protection device of electric food steamer work

Electric food steam ovens are important equipment in modern kitchens. During the cooking process, safety issues have attracted much attention. Among them, the overheating protection device is one of the keys to ensuring user safety.

Basic principles of overheating protection devices
The overheating protection device is a safety protection device used to monitor and control the temperature of the heating system of an electric food steam oven. The basic principle is to monitor the temperature of the heating system in real time through a temperature sensor. When the temperature exceeds the set safety threshold, the power supply is automatically cut off and heating is stopped to prevent the heating system from being damaged or causing safety accidents due to overtemperature.

The role of temperature sensor
The temperature sensor is one of the core components of the overheating protection device and is used to monitor the temperature of the heating system. Typically, temperature sensors are installed at key locations in the heating system, such as on the surface of heating elements or heating tubes. Once the temperature sensor detects that the temperature of the heating system exceeds the set safety threshold, it will send a signal to the control system to trigger the overheating protection device.

Control system response
Generally speaking, electric food steam ovens are equipped with intelligent control systems for monitoring and controlling the working status of the heating system. When the control system receives the signal sent by the temperature sensor, it will respond immediately and perform the corresponding operation. The overheating protection device will automatically cut off the power supply and stop heating to reduce the temperature of the heating system and prevent the heating system from being damaged due to overtemperature.

How to cut off the power
There are usually two ways for an overheating protection device to cut off power: one is to cut off the circuit through a circuit breaker or switch, causing the heating system to cut off power and stop heating; the other is to control the power supply to reduce the output voltage of the power supply to Cool down and stop heating within a safe range. No matter which method is used, the safety of the heating system and users can be effectively protected.

Automatic reset function
Some electric food steam ovens are equipped with an overheat protection device with an automatic reset function. Once the temperature of the heating system drops to a safe range, the overheating protection device will automatically resume normal operation and re-energize the heating to ensure that the equipment continues to operate in a safe working condition.
