Abstract
This invention relates to an improvement in electric kettles and in particular to the temperature controls for such kettles. The temperature control is adjustable to provide a variation in operating temperature of the heating element of the kettle and thus control the wattage input to the kettle. By this means it is possible to control the rate at which water is boiled or evaporated from the kettle. By setting the temperature control to its highest heat position, full wattage is supplied to the heater element to bring the water in the vessel to a boil and vapourize the contents thereof in the shortest possible time. If the temperature controller is left in the high heat position the kettle will evaporate at an approximate rate of two quarts of water in one hour. If the control is set to the low end of the range the contents will be brought up to a boil condition in the same time as if the thermostat were set on the high heat position, but the same amount of water will be evaporated in 12 to 15 hours. No matter which setting is used the temperature control is effective to protect the kettle during a 'boil dry' overheat cycle.
