Zusammenfassung: | An electric kettle (1) according to the present invention includes a container for receiving water and a base (60) on which the container is seated. The container includes a handle (40), a body (10) forming a space in which water is received, a lid (20) for opening or closing the open upper side of the body (10), a heating module (50) mounted on the lower surface of the body (10) to heat water in the body (10), a capacitor, a memory (450), and a controller (410) which detects the voltage of the capacitor according to a preset period and performs a keep-warm operation on the basis of a voltage difference between a first voltage of the capacitor, which is currently detected, and a second voltage of the capacitor, which has been previously detected. When the body (10) is seated on the base (60), commercial power is supplied to the base (60) and the capacitor is charged by power transferred through the base (60), |
