A reservoir of a liquid heating appliance includes a first chamber and a second chamber, separated by a partition. A heating arrangement is arranged to heat liquid in the first chamber. A first valve, a second valve and a float valve are disposed in the partition to selectively allow liquid to flow between the first and second chambers. Respective lines joining the first and second valves to a center of the partition have an obtuse angular separation. The first and second valves are selectively closed by a valve closure member. The float valve includes a floating valve member arranged to float and mate with a valve seat to prevent the flow of liquid. A liquid outlet in the first chamber connects with a dispense outlet on the appliance to allow liquid to be dispensed when the first and second valves are closed.

An actively heated mug, travel mug, baby bottle, water bottle or liquid container is provided. The mug, travel mug, baby bottle, water bottle or liquid container can include a body that receives a liquid therein and a heating or cooling system at least partially disposed in the body. The heating or cooling system can include one or more heating or cooling elements that heat a surface of the receiving portion of the body and one or more energy storage devices. 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.

The present invention discloses a heating device for a kettle, comprising an enclosure, a radiator fan, a rack, a core PCB, a wire coil, and a temperature sensor in the enclosure. A heating platform which has a housing cavity is arranged on the upper part of the enclosure. The radiator fan is mounted at the bottom of the enclosure. The rack is fixed inside the enclosure. The core PCB is configured in the lower part of the rack and above the radiator fan. The wire coil which is provided with a heat coil is installed on the rack, and the temperature sensor is electrically connected with the core PCB.

An actively heated drinkware container includes a vessel with a chamber that receives and holds a volume of liquid. The drinkware container includes a heating module with a first heating element operable to heat one portion of the chamber and a second heating element operable to heat another portion of the chamber, the second heating element spaced from the first heating element. Operation of the first and second heating elements generates a circulation current in the volume of liquid in the chamber that mixes the liquid and diffuses a temperature of the liquid to thereby reduce temperature stratification of the liquid in the chamber and so that a temperature of the liquid throughout the volume of liquid in the chamber is approximately uniform.

An arrangement is provided comprising a vessel (1) for holding a liquid. The arrangement further comprises at least one of a controllable lock (3) to controllably enable a release of said vessel from a support (2) and a controllable lock (4) to controllably enable opening of said vessel (1). The arrangement further comprises a controller (5) to control the at least one controllable lock. The arrangement is provided with a sensor unit (6) including at least one sensor to sense a mechanical interaction occurring when the vessel is gripped and to issue a sense signal (C.sub.6) that is indicative for said mechanical interaction, wherein said controller controls the at least one controllable lock (3, 4) dependent on said sense signal (C.sub.6) and on one or more safety conditions.

In a portable container system for heating a beverage generally, the system includes a container for containing a beverage to be heated. The container generally has a bottom and a side wall together defining an internal reservoir containing the beverage to be heated. A base of the system is operable to heat the container at the bottom thereof. The base is constructed of multiple layers generally including at least a top barrier layer, an electrically non-conductive bottom barrier layer and a thin film heating element intermediate the top barrier layer and the bottom barrier layer.

A foldable electric kettle has a base, a folding body and a holding mount. The base has a connecting segment and a heating seat. The connecting segment has an engaging protrusion and an engaging surface. The folding body is mounted on and connected to the base and has an engaging segment, a folding segment and a neck. The engaging segment is formed on a bottom of the folding body, is mounted in the connecting segment and has an engaging groove and an engaging strip. The holding mount is an annular metal panel, is mounted in the folding body, is connected securely to the base, and has a clamping face abutting against the upper abutting face of the engaging strip. The abutments between the engaging surface, the abutting faces and the clamping face can mount the folding body securely on the base.

An electric kettle may include: a body receiving water or food therein; a lid configured to shield an open upper side of the body; a base provided at a lower side of the body and configured to support the body; a heating module provided in a side of the body and configured to apply heat to the body such that the content contained in the body is heated; and a handle provided at a side of the body and configured to be held by hand, wherein a control means is provided in the handle, the control means being configured to control power supplied to the heating module or to control a temperature of the content contained in the body. According to such a configuration of the electric kettle, there is an advantage in that the malfunction or failure of the electric kettle is prevented.

An actively heated or cooled food container can have a lid movable between an open and a closed position and an insulated body to which the lid can be attached. The insulated body can have a sidewall that defines a perimeter of the container body and a base, the sidewall and base defining one or more chambers that can be sealed by the lid. The food container can have a temperature control system that can include one or more heating or cooling elements in thermal communication with one or both of the sidewall and the base and operable to heat or cool one or both of the sidewall and the base to thereby heat or cool the one or more chambers in the food container.
