Electric kettle

An electric kettle, comprising:

• a power supply base;
• and
• a kettle main body removably placed on the power supply base,
• wherein the kettle main body has:
• a container;
• a heater provided on the container;
• a water amount sensor that detects an amount of water in the container;
• a water temperature sensor that detects a current temperature of the water in the container;
• a first display part that displays information on the amount of water detected by the water amount sensor,
• a heater control part that controls the heater such that, after the current temperature reaches a desired temperature and until a heat retention time elapses, the current temperature is maintained at or higher than a heat retention temperature;
• and
• a first control part that controls the first display part such that, after the current temperature reaches the desired temperature and the heat retention time elapses, when the current temperature falls to a safety temperature lower than the heat retention temperature, the first display part is turned off,
• wherein the power supply base has:
• a power supply cable to be connected to a utility power supply;
• an operation part that receives a user operation concerning the desired temperature of the water;
• a power supply circuit that generates a driving power for the heater from an electric power supplied from the utility power supply;
• and
• a second display part that displays at least one of the current temperature and the desired temperature, wherein
• a second control part that controls the second display part such that, after the current temperature reaches the desired temperature, the second display part is turned off when after the current temperature falls to the safety temperature.
