Abstract
A food warming device assembly supported on legs comprises a stand or a frame having a heater supporting shelf for supporting a tray-like food container, an opening disposed in the heater supporting shelf, a gas burner extending into the opening and supported therein by an annular flange, and a control box containing a fuel cartridge connected to the gas burner by means of an automatic piezo-electronic ignition line and a fuel supply line for automatically igniting and controlling the supply of fuel to the gas burner, whereby the food warming device assembly can be used to maintain food in a warm condition in a controlled manner.
Claims8
A portable food heating assembly used in food warming devices which comprises:
- at least one portable gas burner assembly, said gas burner assembly containing mounting means for removably mounting said gas burner within the food warming device;
- a portable control box separate from said gas burner and containing a fuel cartridge and a piezo-electric element;
- a flexible fuel supply line;
- and
- a flexible piezo-electric ignition line, said flexible fuel supply line and said flexible piezo-electric ignition line being removably connected to said portable control box for controlling the supply of fuel to said gas burner and igniting the gas at said gas burner, wherein the fuel line and the flexible ignition line form elements of the circuit to conduct the spark generated by the piezo-electric element to the burner so that the portable gas burner assembly can be selectively separated a predetermined distance from the portable control box containing said fuel cartridge so that the heating assembly can readily adapt to the environment in which it is used.
