ABSTRACT:
A cooking stove useful for all types of cooking, having a semi-conical outer housing and an inverted semi-conical firebox inserted therein. The firebox has a set of openings in its periphery towards the bottom portion thereof which the covered by a ring having similar openings which can be rotated to allow air to flow into the firebox or to prevent the flow of air into the firebox. The housing also has openings which allows air to flow into the area between the housing and the firebox. The interior of the firebox contains a fuel rack upon which fuel such as charcoal briquets or the like may be placed and ignited. The stove can be covered with a grill upon which food may be cooked, or other utensils may be placed on the stove such as wok, a Dutch oven, a steamer, etc. Air flows through the housing and through the venting ring into the firebox where it is heated by the fuel, and then moves upwardly through the firebox to heat the food placed on a grill or in a cooking utensil located at the top opening of the firebox. Because of the distance between the fuel and the top opening of the firebox, food is substantially heated by the rising hot air, instead of by the radiant heat of the burning coals as in prior art devices.
