9. A cooking apparatus according to claim 1 wherein the apparatus includes a first grid or mesh located towards a bottom of the apparatus on to which fuel is placed and prevents fuel from contacting the housing in use.

10. A cooking apparatus according to claim 9 wherein the first grid or mesh is located in or on a horizontal plane and prevents the fuel from contacting the bottom of the housing in use and a second mesh or grid is located above the first mesh or grid in use to prevent food from falling onto the fuel located below the first mesh or grid.

11. A cooking apparatus according to claim 10 wherein the second mesh or grid includes one or more further formations onto which at least part of the skewers can be located in use.

12. A cooking apparatus according to claim 1 wherein the housing is divided or portioned into at least a head section and a body section and the head section and the body section are engaged together in use at least whilst cooking or for storage.

13. A cooking apparatus according to claim 12 wherein the head section and the body section can be disengaged or detached to allow cleaning, removal of food, or addition/removal of fuel.

14. A cooking apparatus according to claim 12 wherein the apparatus includes a lid member located on or attached to the head section.

15. A cooking apparatus according to claim 14 wherein the rib or baffle members are located on the head section.

(3) FIGS. 2A to 2D show cross sectional views of the apparatus in accordance with one embodiment of the invention;

(4) FIGS. 3A to 3C illustrate the various means by which the apparatus is assembled or attached together in accordance with one embodiment of the invention; and

(5) FIGS. 4A to 4F illustrate a configuration of the head section in accordance with one embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION

(6) FIGS. 1 and 2 show an outdoor cooking device 2 which is egg or ovoid shaped, the shell of body 4 is constructed primarily from aluminium. Using aluminium has provided the optimum balance of mass for heat retention and conduction over weight to make the whole unit practical for consumer use. Ceramic outdoor cooking products like traditional Indian tandoors are very heavy (for example 70 kg for a similar size unit to the embodiment depicted here which is 15 kg).

(7) The body 4 is divided circumferentially into a head portion 6 and a body portion 8. The head portion 6 and the body portion 8 are attached together by hook or latch means as depicted in FIG. 3A.

(8) The head portion 6 includes a number of equidistantly and circumferentially spaced notch or slot formations 10 which are adapted to receive skewers 12. Food items, typically meats such as chicken and lamb etc., can be hung on the skewers and then placed into a cooking area inside the housing 4. Once inside the food items are cooked, or at least warmed, over fuel (not shown). The fuel is typically charcoal or similar, and located in the bottom of the housing.

(9) To insert the food, rather than detaching the head portion 6 from the body, 8, the device 2 includes a lid 14 which covers an opening 16 in the top of the device through which food items and/or skewers can be inserted and/or removed in use. The opening 16 has been designed to be large enough for skewers and other devices to be lowered into the cooking area, which can hold whole chickens and lamb legs. This means that the whole upper half doesn't have to be opened which would drastically compromise heat retention. Furthermore the egg shape from the testing has proved to be a perfect shape that provides maximum functional usage when using skewers. It maximises the cooking area in the top half chamber whilst providing enough air flow around the food to cook the food evenly. The ovoid shape also gives sufficient separation between the food and the charcoal level so that the food is not too close to burn. It also enable fatty foods to be placed high enough above the charcoal so that by the fat drips onto the hot charcoal it is sufficiently diffused to not flame and char the food.

(10) The head portion 6 also includes a pair of handles 18 so that the head portion 6 can be removed from the body portion 8 to facilitate cleaning, insertion/removal of fuel etc. The device 2 can be placed on legs or a stand. In this embodiment three equally spaced legs 20 are used to keep the longitudinal axis of the device substantially vertical, with the narrow end of the oval at the bottom.

(11) Turning now to the cross sectional FIGS. 2A and 2B which show the typical location of the skewers 12 through the slots 10 formed in the housing 4. Once inserted into the slots the skewers 12 dependent downwardly through the cooking area inside the body and the ends of the skewers are located on a plate 22 or mesh grid positioned above the bottom area of the body 8 in which the charcoal is usually situated.

(12) FIGS. 2A and 2B, as well as FIGS. 4A-4F also show the location of a number of rib or baffle portions 24 which, in this embodiment, are located on the inside surface of the head portion 6. FIGS. 4B and 4F show the shape and configuration of these linear baffles or ribs 24. The internal ribs 24 in the head portion 6 of the body 4 maximise the heat generated by the charcoal fuel by: a) Breaking up the airflow and allowing greater movement of heat around the top half before escaping through the top vent aperture 16 or being conducted through the aluminium body 4; and b) the ribs add mass to the top half holding the heat and radiating the heat back into the cooking chamber. This has been evidenced during trials where surfaces of the cooked food have charred quite evenly.
