Abstract: Disclosed herein is an electric pot having an improved relay installation position. The electric pot includes a pot main body that is provided with a magnetic field generator generating a magnetic field at a lower portion of the pot main body, and a supporter that includes a magnetism detection sensor detecting magnitude of a magnetic field generated by the magnetic field generator and, based on the detected magnitude of a magnetic field, generating a voltage and that includes a comparator comparing the voltage generated by the magnetism detection sensor with a predetermined reference voltage and, based on the comparison, controlling a switchover operation of a relay part, thereby controlling the relay part through a simple circuit configuration and through magnetic field generation and detection means without an additional communication means.

Abstract: An electric pot may have an improved relay installation position. The electric pot may include a supporter and a pot main body provided with a heater driven to provide heat through an electric connection with connection terminals. The supporter may include a relay part that optionally switches between a connection of the power supply to a third connection terminal and a disconnection of the power supply to the third connection terminal.
