A round mechanical timer in an electric steamer is used to control the cooking duration manually. Here's how it works:
Function of the Mechanical Timer:
Manual Time Setting – The user turns the timer dial to the desired cooking time (e.g., 10, 20, or 30 minutes).
Countdown Mechanism – Once the steamer is turned on, the timer starts counting down automatically.
Power Cutoff – When the time elapses, the timer triggers a switch that cuts off power to the heating element, stopping the steaming process.
How It's Used in an Electric Steamer:
Fill the Steamer – Add water and food to the steamer.
Set the Timer – Rotate the dial to the required cooking time.
Start the Steamer – Turn on the power; the timer begins counting down.
Automatic Shutoff – The steamer turns off when the timer reaches zero.
Advantages:
Simple & reliable (no complex electronics).
No battery needed (works mechanically).
Prevents overcooking by automatically shutting off.
