         9 . The household cooking appliance of  claim 1 , wherein a first panel of the mechanically coupled panels includes a first flange and a second panel of the mechanically coupled panels includes a second flange adjacent to the first flange of the first panel,
 wherein at least one of the first flange and the second flange includes an emboss extending along a longitudinal centerline of the at least one of the first flange and the second flange,   wherein the seal is disposed in the emboss between the first flange and the second flange, and   wherein the first flange is mechanically coupled to the second flange with the seal therebetween.   
     
     
         10 . The household cooking appliance of  claim 9 , wherein the first flange and the second flange include matching embosses extending along a longitudinal centerline of each of the first flange and the second flange, and
 wherein the seal is disposed between the first flange and the second flange and at least partially within the matching embosses.   
     
     
         11 . The household cooking appliance of  claim 10 , wherein the seal is disposed between the first flange and the second flange and entirely within the matching embosses. 
     
     
         12 . The household cooking appliance of  claim 9 , wherein the first flange is mechanically coupled to the second flange by a plurality of fixation elements, and
 wherein each of the plurality of fixation elements is alternately located on opposite sides of the emboss.   
     
     
         13 . The household cooking appliance of  claim 9 , wherein the seal has one of an oval cross-section and a circular cross-section corresponding to at least a portion of a cross-section of the emboss. 
     
     
         14 . The household cooking appliance of  claim 1 , wherein a first panel of the mechanically coupled panels includes a flange adjacent to a surface of a second panel of the mechanically coupled panels,
 wherein the seal is disposed between the flange of the first panel and the surface of the second panel, and   wherein the flange of the first panel is mechanically coupled to the surface of the second panel with the seal therebetween.   
     
     
         15 . The household cooking appliance of  claim 14 , wherein the flange of the first panel is mechanically coupled to the surface of the second panel by at least one fixation element, and
 wherein the at least one fixation element is centrally located along a longitudinal centerline of the flange of the first panel.   
     
     
         16 . The household cooking appliance of  claim 15 , wherein the at least one fixation element is centrally located along the longitudinal centerline of the flange and a longitudinal centerline of the seal. 
     
     
         17 . The household cooking appliance of  claim 14 , wherein the seal is a flat seal. 
     
     
         18 . The household cooking appliance of  claim 14 , wherein at least one of the flange of the first panel and the surface of the second panel includes an emboss extending along a longitudinal centerline of the flange,
