A system for providing mains power to a cordless appliance, the system comprising a coupler and a complementary coupler on the appliance. The coupler has symmetrically configured concentric power terminals, which are connected to a mains power source in use, and a magnetic coupling region disposed concentrically around an outer periphery of the power terminals. The complementary coupler has complementary power terminals configured to engage with the symmetrically configured concentric power terminals of the coupler, and an engaging region disposed concentrically around an outer periphery of the complementary terminals. A magnetic force provides a mutual attraction between the magnetic coupling region and the engaging region, thereby engaging the power terminals and complementary power terminals and establishing an electrical connection between the coupler and the appliance.

The mug, travel mug, baby bottle, water bottle or liquid container can include a wireless power receiver that wirelessly receives power from a power source and control circuitry configured to charge one or more power storage elements and to control the delivery of electricity from the one or more power storage elements to the one or more heating or cooling elements. The mug, travel mug, baby bottle, water bottle or liquid container also can have one or more sensors that sense a parameter of the liquid or sense a parameter of the heating or cooling system and communicates the sensed information to the control circuitry. The control circuitry can turn on, turn off, and/or operate the heating or cooling element to actively heat or cool at least a portion of the body to maintain the liquid in a heated or cooled state generally at a user selected temperature setting based at least in part on the sensed parameter information. The mug, travel mug, baby bottle, water bottle or liquid container can also be paired with a remote device or mobile electronic device to send or receive communications or commands.

An electric kettle may include a body made of stainless steel and having a cylindrical shape with an open upper surface and an open lower surface, a heating module configured to form a bottom of a space in which fluid, such as water is contained inside of the body and heat the fluid, a handle that protrudes from an upper portion of an outer surface of the body, and a base configured to support the body at a lower side and supply power to the heating module in a state in which the body is seated. The body may include an outer body configured to form the outer surface of the body, an inner body connected to the outer body inside of the outer body and configured to form a space in which fluid is contained, a heat insulation space between the outer body and the inner body, and at least one body hole opened in the lower surface of the body and configured to communicate with the heat insulation space.

An appliance (210) to heat a liquid, the appliance (21) including: a vessel (212) to receive the liquid to be heated, the vessel (212) having a generally central upright longitudinal axis (218), a bottom housing (220), and a side wall (222) extending upwardly from the bottom housing (220), with a portion of the bottom housing (220) and side wall (222) at least partly enclosing a chamber (234) within which the liquid is heated; and a heating element (238) in thermal communication with the chamber (234) so that heat generated by the element (238) can be delivered to the liquid via convection, wherein the housing (210) includes a deformable sealing member (268) sealingly associated with the element (238) to sealingly connect the element (238) and bottom housing (220), with the member (268) inhibiting transmission of sound from the chamber (234).

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.
