Electric kettle and power supply unit

A power supply unit that is configured such that a kettle body is placed thereon, the kettle body having a power receiving connection terminal configured to receive power from an external power source, and a heating part configured to heat liquid contained in the kettle body by the power the power receiving connection terminal receives, the power supply unit comprising:

• a plate part that includes a wall and a base, the wall extending orthogonally from the base such that the plate part defines a first surface of the wall and the base and a second
• surface of the wall and the base opposing the first surface of the wall and the base;
• a power supply base that is arranged on a side of the first surface of the plate part and configured such that the kettle body is placed on top thereof, the power supply base having a power supply connection terminal that is configured to be electrically removably connected to the power receiving connection terminal;
• and
• a mounting unit that is arranged on a side of the second surface of the plate part and configured such that a battery pack is removably coupled thereto as the external power source for supplying power to the heating part via the power supply connection terminal and the power receiving connection terminal, wherein:
• the plate part is connected to the power supply base,
• the wall is offset from a rear edge of the base such that the wall divides the base into a first region that accommodates the kettle body and a second region that accommodates the power supply unit, and
• the mounting unit is arranged on the second surface of the wall and the base.

An electric kettle, comprising:

• a kettle body having a power receiving connection terminal configured to receive power from an external power source, and a heating part configured to heat liquid contained in the kettle body by the power the power receiving connection terminal receives;
• and
• a power supply unit configured such that the kettle body is placed thereon, and configured to supply power to the kettle body,
• the power supply unit including:
• a plate part having a first surface and a second surface;
• a power supply base that is arranged on a side of the first surface of the plate part and configured such that the kettle body is placed on top thereof, the power supply base having a power supply connection terminal that is configured to be electrically removably connected to the power receiving connection terminal;
• a mounting unit that is arranged on a side of the second surface of the plate part and configured such that a battery pack is removably coupled thereto as the external power source for supplying power to the heating part via the power supply connection terminal and the power receiving connection part;
• a controller that is configured to calculate an amount of liquid that can be heated up to a predetermined temperature based on (i) a predetermined relation between amounts of the liquid in the kettle body and power required to heat each amount of the liquid up to the predetermined temperature and (ii) a residual capacity of the battery pack that is obtained via the mounting unit;
• and
• a visual display that is provided on the power supply unit and configured to display the amount of the liquid calculated by the controller.
