A deep fat fryer includes a plurality of open-ended burner tubes that are end-welded between opposing walls of the fry pot. A front heat shield is formed from a pair of steel sheets and is positioned between the wall of the fry pot and the burner so that the end weld is protected from the burner flame. Airflow is established over the end weld during operation of the burner. A rear heat shield is positioned in the rear of the burner tube and blocks the rear end weld from the hot combustion products. The spaces between the rear heat shield and the burner tube inner wall and the fry pot outer wall are filled with insulation.

A natural or LP gas-fired laminated griddle top structure providing an even distribution of heat over its cooking surface is disclosed. The griddle top includes an upper plate formed from a relatively thick iron or steel plate and a plurality of relatively thick lower plates formed from a dissimilar material having a high thermal conductivity. A thermal break is provided between adjacent lower plates and each lower plate has a channel provided therein for the receipt of a temperature sensing device. In addition, laterally extending grooves are provided in the bottom surface of the lower plates increasing the resulting heat transfer surface improving the thermal efficiency of the griddle top. One or more natural or LP gas-fired burners and associated controls are provided adjacent each lower plate permitting the entire cooking surface to be maintained at the same temperature or portions thereof to be maintained at different temperature, if desired.

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.
