Abstract:
1. A method of heating a liquid using an apparatus that is operable by a supply voltage that is either a first AC voltage from a first source or a second AC voltage from a second source, wherein the first source is different from the second source, the method comprising: providing a container for retaining a liquid to be heated; providing a heating element; coupling the heating element directly to the supply voltage regardless of whether the supply voltage is the first AC voltage or the second AC voltage; providing a power supply capable of receiving a variety of input voltages; coupling an input of the power supply directly to the supply voltage regardless of whether the supply voltage is the first AC voltage or the second AC voltage, wherein the power supply and the heating element are coupled in parallel to the first AC voltage or the second AC voltage; providing a DC output from the power supply; providing a controller; coupling the controller to the DC output from the power supply; providing a switch coupled to the controller and coupled to the heating element, the controller opening and closing the switch to control heating of the liquid in the container, the first AC voltage being applied to the heating element when the switch is closed when the beverage heating apparatus is operated in a first area, and the second AC voltage being applied to the heating element when the switch is closed when the beverage heating apparatus is operated in a second area; operating user inputs to signal the controller coupled to the DC voltage output to control the operation of the heating element to heat liquid contained in a container.
