摘要： The present invention discloses a method for determining whether water inside an electric kettle is boiling. The technical problem to be solved by the invention is to accurately detect whether water is boiling inside the electric kettle, and turn off the heating power supply when the water is boiling. The present invention comprising the following steps: (1) setting a temperature sensor, a microprocessor and a control circuit in the electric kettle; (2) detecting a temperature of the water inside the electric kettle, a temperature of a bottom heating unit which is in contact with the water, or a temperature of the sidewall of the electric kettle in real time by the sensor; (3) calculating a temperature change rate and comparing the temperature change rate with that of a period prior to the current period by the microprocessor; and (4) sending a signal to the control circuit when the temperature change rate decreases and reaches a minimum value. Compared with the prior art, the present invention adopts a microprocessor to determine whether the water inside the electric kettle is boiling according to the variation of the temperature change rate during the heating process, and send a signal to the control circuit to turn off the heating power supply when the water is boiling. The present invention provides an accurate method of determining the water boiling inside the electric kettle and provides a timely control of power-breaking to avoid any potential safety hazard and accident.

摘要： The present invention discloses a control method for preventing an electric kettle from dry boiling, and the technical problem to be solved by the invention is to accurately determine the temperature rise in the electric kettle, and turn off the heating power supply correspondingly. The method includes the following steps: (1) setting a temperature sensor, a microprocessor and a control circuit in the electric kettle; (2) detecting a real-time temperature inside the electric kettle by the sensor; (3) calculating a temperature change rate in accordance with the detected temperature and comparing the temperature change rate with a preset value by the microprocessor; and (4) sending a signal to the control circuit if the temperature change rate is grater than the preset value. Compared with the prior art, the present invention adopts a microprocessor to calculate the temperature change rate and the acceleration of change of the temperature, and compares those rates with their preset value. When the temperature change rate and the acceleration of change of the temperature exceed the preset values, a signal is sent to the control circuit to turn off the heating power supply The present invention provides an accurate method of estimating the temperature rise inside the electric kettle and provides a timely control of power-breaking to avoid any possible damage.
