Embodiment Construction

[0061] Figure 1 shows an example of an oven 1 known in the art. The oven 1 has a main body 3 and a cover 5 . The lid 5 can be opened and closed on the main body 3 using the handle 7 .

[0062] The oven 1 comprises a lower interior cavity 8 defined by a body 3 and an upper interior cavity 9 defined by a cover 5 .

[0063] At the bottom of the lower cavity 8 of the body 3 is the bottom wall 4 . The one-piece designed ceramic combustion chamber 10 is inserted into the lower inner cavity 8 of the main body 3 and rests on the bottom wall 4 . The combustion chamber 10 holds a grate 11 which in turn will hold combustion material, such as blocks. A fire ring 13 is placed adjacent to the combustion chamber 10 and holds a grill grate 15 on which food cooked by the oven 1 is placed.

[0064] As shown in FIG. 1 , the main body 3 of the oven 1 has a vent door 21 movable from a fully closed position shown in FIG. 1 to a fully open position shown in FIG. 2 . The opening provided by the ...

Abstract

A firebox for a grill is provided. The firebox has a shell, an insulation layer, and a firebrick layer. The firebrick layer comprising a plurality of firebricks that form an inner peripheral surface of the firebox. The insulation layer formed between the firebrick layer and the shell or the insulation layer forming the outermost layer of the firebox. The shell preventing the collapse and / or unwanted airflow into the internal cavity of the firebox if a fracture is formed in the firebrick layer.

Description

technical field [0001] The present invention relates generally to ovens for cooking, and more particularly to a combustion chamber for an oven. Background technique [0002] Many modern ovens have a one-piece ceramic designed combustion chamber. The use of ceramics in combustion chambers has many advantages compared to other materials, the main being excellent thermal insulation. [0003] The ceramic burners retain heat for a long time as they can be used for grilling, smoking and roasting, making them very versatile. This allows the oven to have a constant temperature as low as 225°F and as high as 750°+F. [0004] Plus, using the ventilation system typical in an oven, precise control over airflow is maintained, allowing the oven to function more like a wood-burning oven and can be used for smoking, roasting, or roasting anything. [0005] However, modern ovens are not without their drawbacks. For example, a major problem faced by oven and combustion chamber manufacture...
