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.
Driven by a small DC motor (often 12V or 18V) powered by a small internal transformer or power supply board.
Once boiling, the main thermostat opens its contacts. The circuit then redirects power through the secondary "Keep-Warm" TÉN or a control relay. shema jelektrochajnika termosa
) that permanently breaks the circuit if the thermostats fail and the pot overheats dry.
), the keep-warm thermostat closes, activating the low-power heater until the water is back to the target temperature. In the context of home appliances, a "shema"
): Monitors the temperature to cycle the smaller heating element on and off. Thermal Fuse ( ): A one-time safety device (usually rated for ~
A manual bellows-style pump that works without electricity. 2. Operational Logic (How the Circuit Works) Once boiling, the main thermostat opens its contacts
Scale buildup on the sensors can cause the thermopot to switch off too early or fail to maintain the correct temperature.
