Abstract:
1. A process of controlling an operation of an electric kettle comprising a heat-up circuit to heat up a predetermined volume of water in a controlled manner, wherein said process comprises the steps of: (a) initializing a microprocessor to detect a temperature of said water via a temperature sensor in said electric kettle so as to set a system parameter; (b) checking a status of said heat-up circuit, wherein said heat-up circuit is adapted to operate at an “ON” mode or an “OFF” mode, and determining a heat up time period for continuously heating up said water in said kettle; (c) setting a preserve status of said water for maintaining said water at a preserve temperature; (d) heating said water in said kettle in responsive to a condition of said water so as to heat up said water to said preserve temperature when said a temperature of said water is less than that of said preserve temperature; (e) stopping heating said water in said kettle when said temperature of said water in said kettle reaches said preserve temperature; and (f) cutting off power supply to said heat-up circuit by a cut off circuit in a controlled manner, so that said cut off circuit is arranged to cut off said power supply to said heat-up circuit for preventing said water from being totally evaporated.
