The working principle of the electric kettle is that the steam generated when the water boils deforms the bimetal of the steam temperature sensing element, and the power switch is pushed by the deformed lever principle, so that the electric kettle is automatically powered off after the water boils. Its power failure can't reset itself, so the kettle won't automatically reheat after power failure. ?
First weight: steam switch, when the water boils, the steam switch will cut off the power supply of the kettle; Second, dry burning protection: If the steam switch is not activated, the water will continue to burn and decrease. When the water is below the lowest water level or dried up, the bimetal on the other thermostat will cut off the power supply of the kettle; Third, if none of the above works, as the temperature rises, a plastic push rod in the thermostat will melt, so that the kettle will be cut off.
