ABSTRACT:
A liquid heating vessel, such as a kettle, enables user selection of the temperature to which the liquid is to be heated. A thermal sensor is provided which is responsive to the temperature of the heating element. During the heating cycle, the operation of the heating element is interrupted, and temperature samples are obtained as the element cools. Analysis of the temperature decay function of the heating element during the interruption enables the liquid volume to be estimated, as well as the time required to heat the liquid to the selected temperature.
