ABSTRACT:
FIELD OF THE INVENTION
The invention relates generally to a cooking system and, more particularly, to a versatile outdoor cooking system which permits rapid assembly and disassembly for easy storage and transportation
BACKGROUND OF THE INVENTION
Cooking outdoors is well-known and many system's have been developed to facilitate cooking outdoors. However, the systems that are available either are limited in desirable features or, if they are provided with many desirable features, are heavy and cumbersome to store and difficult to transport, for example, by one hiking through a wilderness area.
Therefore, what is needed is a lightweight outdoor cooking system which provides desirable features and which may also be easily stored and readily transported.
Many available systems are inefficient by design. Deficiencies include:
Inadequate draft control.
No fire grate.
No Combustion air control.
Open lid designs lose heat, do not reflect heat to food being cooked.
No radiant heat.
Not rain proof or wind proof.
Square shapes are less efficient than parabolic or semi circular shapes.
Painted surfaces absorb heat while unpainted aluminum reflects heat.
Grills with short legs may start grass fires.
Grills with short legs are inconvenient, requiring the user to stoop or squat.
No place to hang implements.
SUMMARY OF THE INVENTION
The present invention, accordingly, provides a system for cooking outdoors which permits rapid assembly and disassembly with the feature that when disassembled all the pieces lie flat for easy storage and transportation. Additionally, the system includes a number of additional features which enable it to be used in a number of different cooking modes as, for example, a grill, a baker, a boiler, a smoker, a steamer, a deep fat fryer, and the like. Some of these modes may be carried out simultaneously. A dutch oven may be utilized in the present invention, without a ground fire, and can be used despite rain or wind. Improved draft control makes possible starting of charcoal fire, even in rain, by positioning body and lid ends to control draft.
