 further comprising a burner cover which covers the burner tube, and   wherein at least a portion of the ignition unit is disposed in the burner cover.   
     
     
         9 . The cooking device of  claim 8 ,
 wherein the ignition unit comprises an ignition bar that faces at least one of the plurality of the gas outlet holes,   wherein the burner cover includes an opening through which air flowing from the cooking chamber passes, and   the ignition bar is positioned in an area between the opening and the burner tube.   
     
     
         10 . The cooking device of  claim 5 ,
 wherein the burner tube includes an inner surface and an outer surface, and   wherein the plurality of the gas outlet holes are provided on the inner surface of the burner tube.   
     
     
         11 . The cooking device of  claim 5 ,
 further comprising a burner cover provided in the frame to form a combustion chamber that is partitioned from the cooking chamber,   wherein the burner cover includes:   an opening formed by opening in a forward and backward directions, through which air flowing from the cooking chamber passes, and   an introduction hole formed by opening downward, through which air supplied to the burner tube is introduced.   
     
     
         12 . The cooking device of  claim 11 ,
 wherein the frame comprises:   the rear wall;   an upper wall forming an upper surface of the cooking chamber;   a bottom wall forming a lower surface of the cooking chamber; and   a pair of side walls forming both side surfaces of the cooking chamber,   wherein the introduction hole is formed at a lower part of the burner cover, and   wherein the bottom wall includes a through-hole into which the lower part of the burner cover is inserted.   
     
     
         13 . The cooking device of  claim 1 ,
 further comprising a burner cover provided in the frame to form a combustion chamber that is partitioned from the cooking chamber,   wherein the burner cover includes:   an opening formed by opening in a forward and backward directions, through which air flowing from the cooking chamber passes, and   an introduction hole formed by opening downward, through which air supplied to the combustion   
     
     
         14 . The cooking device of  claim 1 ,
 further comprising a burner cover provided in the frame to form a combustion chamber that is partitioned from the cooking chamber,   wherein the burner cover comprises:   a first cover covering the burner at a front side of the burner, and   a second cover covering the burner at a rear side of the burner,   wherein the first cover comprises:   a first plate comprising a first opening through which air flowing from the cooking chamber passes, and   a first insertion part formed at a lower end of the first plate and having a first introduction hole for introducing air into the combustion chamber,   wherein the second cover comprises:   a second plate comprising a second opening through which heated air is discharged from the combustion chamber, and   a second insertion part formed at a lower end of the second plate and having a second introduction hole for introducing air into the combustion chamber.   
     
     
         15 . The cooking device of  claim 14 ,
 wherein the first insertion part and the second insertion part are spaced apart from each other to form a third introduction hole for introducing air into the combustion chamber.
