Abstract
The invention discloses an improved electric kettle control circuit. By virtue of a steam-type automatic-power-off switch, steam is generated after water in an electric kettle is boiled, so that a metal sheet in the a steam switch deforms due to heating and then automatically bounces up the switch, and the a circuit is disconnected; a temperature controller is adopted, so as to achieve achieve cause an anti-dryout protection effect in the electric kettle; a thermal fuse is adopted, when the switch is invalid, the thermal fuse is fused along with an increase of the temperature, so that the electric kettle is powered off. According to the an application design, a light-emitting diode and a current-limiting resistor R are connected in series and are connected with a boiling heater in parallel; when the circuit of the electric kettle is connected, and the boiling heater has a working voltage under in a boiling state, the light-emitting diode emits light so as to indicate that the electric kettle is in a boiling heating state. When the a the water temperature is at higher than 96 DEG C or above, the steam-type automatic-power-off switch is disconnected, then the electric kettle is in a disconnection state, and the light-emitting diode is powered off. The improved electric kettle control circuit is high in safety, low in design cost and favorable in market application prospect.
