Abstract
An automatic cooking vessel includes a container having a water level tube coupled to the lower portion thereof and extending upwardly and outwardly therefrom. A high water level and a low water level sensors are coupled to the interiors of respective portions of the water level tube. The water level tube provides a substantially straight, unobstructed entry to the container for ease of cleaning. Two heating units are positioned in the container above the entry point of the water level tube. Two temperature sensors are coupled to respective thermostats for controlling respective energy flow devices for supplying energy to the respective heating units. The energy flow devices are coupled in series so that for temperatures below a first temperature both heating units are operated and as the temperature approaches a second temperature, equal to the boiling point of water, only one of the heating units operates. Both electric and gas versions of the cooking vessel are shown.
