Abstract
An electric kettle has a kettle body and a power supply unit that is configured to supply power to the kettle body. The power supply unit has a power supply base, a mounting unit and a first detection part. The power supply base is configured such that the kettle body is placed on top thereof, and has a power supply connection part that is configured to be electrically removably connected to a power receiving connection part. The mounting unit is configured such that a battery pack is removably coupled thereto as an external power source for supplying power to a heating part via the power supply connection part and the power receiving connection part. The first detection part is configured to detect that the power supply unit is on a plane.
Claims17
An electric kettle, comprising:
- a kettle body having a power receiving connection part configured to receive power from an external power source, and a heating part configured to heat liquid contained in the
- 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 power supply base configured such that the kettle body is placed on top thereof, the power supply base including a power supply connection part that is configured to be electrically removably connected to the power receiving connection part;
- a mounting unit 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 part and the power receiving connection part;
- and
- a first sensor configured to detect that the power supply unit is placed on a plane, wherein:
- an indicator configured to indicate drive information of the electric kettle;
- and
- a second controller configured to control the indicator based on a detection result of the first sensor, wherein:
- the second controller is configured to cause the indicator to indicate, as the drive information that the power supply unit is not on the plane when the power supply unit is not placed on the plane.
A power supply unit, which is configured such that a kettle body is placed thereon, and configured to supply power to the kettle body, comprising:
- a power supply base configured such that the kettle body is placed on top thereof, the power supply base including a power supply connection part that is configured to supply power to the kettle body;
- a mounting unit that is configured such that a battery pack is removably coupled thereto to supply power to the kettle body via the power supply connection part;
- a first sensor configured to detect that the power supply unit is on a plane;
- an indicator configured to indicate drive information of an electric kettle;
- and
- a second controller configured to control the indicator based on a detection result of the first sensor, wherein:
- the second controller is configured to cause the indicator to indicate, as the drive information that the power supply unit is not on the plane when the power supply unit is not placed on the plane.
An electric kettle, comprising:
- a kettle body having a power receiving connection part 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 part 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 power supply base configured such that the kettle body is placed on top thereof, the power supply base including a power supply connection part that is configured to be electrically removably connected to the power receiving connection part;
- a mounting unit 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 part and the power receiving connection part;
- and
- a sensor configured to detect that the power supply unit is placed on a plane, wherein:
- the sensor includes a switch provided in a lower surface of the power supply unit, and
- the switch is configured to protrude from the lower surface when the power supply unit is not on the plane, while being pushed into the lower surface when the power supply unit is on the plane.
