The safety mechanism of an electric pressure cooker is designed to ensure safe cooking by preventing accidents and maintaining a controlled cooking environment. Here are some common safety features found in electric pressure cookers:
1. Pressure Release Valve: This valve controls the pressure inside the cooker. It allows excess steam to escape when the pressure reaches a certain limit. It ensures that the pressure cooker does not build up excessive pressure, which could cause an explosion.
2. Locking Lid: The lid of the pressure cooker locks securely in place when the cooker is pressurized. It prevents the lid from being opened while there is pressure inside. Some models have additional safety mechanisms like an indicator or lock handle that cannot be turned until the pressure is released.
3. Pressure Sensors and Thermostat: Electric pressure cookers have built-in sensors and thermostats that monitor the pressure and temperature inside the cooker. If the pressure or temperature exceeds a safe level, the sensors will automatically adjust the heat or activate safety measures to prevent any mishaps.
4. Safety Vent and Gasket: The pressure cooker has a rubber or silicone gasket that seals the lid, creating an airtight environment. In case of excessive pressure build-up, the safety vent will release small amounts of steam to gradually reduce the pressure. This prevents sudden release of steam, which could cause burns or injuries.
5. Automatic Shut-off: Electric pressure cookers often come with an automatic shut-off feature. This feature turns off the heat and stops the cooking process once the cooking time is complete or if any safety parameters are exceeded.
6. Overheating Protection: Some models have an overheating protection feature that detects if the temperature inside the cooker is too high. It automatically turns off the heat source to prevent damage to the pressure cooker or any potential hazards.
These safety mechanisms work together to ensure that the pressure cooker operates within safe limits, preventing accidents such as explosions, excessive steam release, or overheating.
