In the context of home appliances, a "shema" (circuit/wiring diagram) for an electric kettle-thermos—commonly known as a —is significantly more complex than that of a standard kettle. While a regular kettle only boils water and shuts off, a thermopot acts as a hybrid device that boils water and then maintains its temperature using a secondary, lower-power heating element.
If the water temperature drops below the set limit (e.g.,
Driven by a small DC motor (often 12V or 18V) powered by a small internal transformer or power supply board.
Scale buildup on the sensors can cause the thermopot to switch off too early or fail to maintain the correct temperature.
): Monitors the temperature to cycle the smaller heating element on and off. Thermal Fuse ( ): A one-time safety device (usually rated for ~
Once boiling, the main thermostat opens its contacts. The circuit then redirects power through the secondary "Keep-Warm" TÉN or a control relay.
