Gas burner assembly

Abstract

A gas burner assembly includes a burner base and a bottom plate. The burner base includes a round burner and an elongated burner. The bottom plate is mounted to the burner base. A Venturi mixing tube of the round burner is positioned or disposed within a collar of the bottom plate.

What is claimed is: 
     
         1 . A gas burner assembly, comprising:
 a burner base having a round burner and an elongated burner, the round burner positioned at a middle portion of the elongated burner, the burner base also defining a Venturi mixing tube of the round burner;   a bottom plate mounted to the burner base such that the bottom plate and the burner base define a fuel chamber therebetween, the bottom plate also having a collar, an end portion of the Venturi mixing tube of the round burner positioned within the collar of the bottom plate.   
     
     
         2 . The gas burner assembly of  claim 1 , wherein the Venturi mixing tube of the round burner is received within the collar of the bottom plate such that the Venturi mixing tube of the round burner and the collar of the bottom plate define a joint therebetween, the joint extending between the fuel chamber and an interior volume of the Venturi mixing tube of the round burner. 
     
     
         3 . The gas burner assembly of  claim 2 , wherein fuel leaking from the fuel chamber flows through the joint into the Venturi mixing tube of the round burner. 
     
     
         4 . The gas burner assembly of  claim 1 , wherein the bottom plate is screwed, riveted or staked to the burner base. 
     
     
         5 . The gas burner assembly of  claim 4 , wherein the bottom plate has a perimeter, the bottom plate mounted to the burner base at the perimeter of the bottom plate. 
     
     
         6 . The gas burner assembly of  claim 1 , wherein the burner base and the bottom plate are formed with discrete material. 
     
     
         7 . The gas burner assembly of  claim 1 , wherein the Venturi mixing tube of the round burner extends downwardly from the burner base such that the Venturi mixing tube of the round burner has a distal end spaced from the fuel chamber, the collar extending downwardly from the bottom plate such that the collar has a distal end spaced from the fuel chamber, the distal end of the Venturi mixing tube of the round burner positioned at the distal end of the collar. 
     
     
         8 . The gas burner assembly of  claim 1 , wherein the Venturi mixing tube of the round burner extends downwardly from the burner base such that the Venturi mixing tube of the round burner has a distal end spaced from the fuel chamber, the collar extending downwardly from the bottom plate such that the collar has a distal end spaced from the fuel chamber, the distal end of the Venturi mixing tube of the round burner positioned within the collar such that the distal end of the Venturi mixing tube of the round burner is spaced apart from the distal end of the collar. 
     
     
         9 . The gas burner assembly of  claim 1 , wherein the bottom plate defines a Venturi mixing tube of the elongated burner. 
     
     
         10 . The gas burner assembly of  claim 1 , wherein the elongated burner extends between a first end portion and a second end portion, the round burner positioned between the first and second end portions of the elongated burner, the elongated burner having flame ports at the first and second end portions of the elongated burner. 
     
     
         11 . A gas burner assembly, comprising:
 a burner base having a round burner and an elongated burner, the round burner positioned at a middle portion of the elongated burner, a Venturi mixing tube of the round burner extending from the burner base;   a bottom plate mounted to the burner base such that the bottom plate and the burner base define a fuel chamber therebetween, a collar also extending from the bottom plate, the Venturi mixing tube of the round burner positioned within the collar of the bottom plate, the collar extending to or past a distal end of the Venturi mixing tube of the round burner.   
     
     
         12 . The gas burner assembly of  claim 11 , wherein the Venturi mixing tube of the round burner is received within the collar of the bottom plate such that the Venturi mixing tube of the round burner and the collar of the bottom plate define a joint therebetween, the joint extending between the fuel chamber and an interior volume of the Venturi mixing tube of the round burner. 
     
     
         13 . The gas burner assembly of  claim 12 , wherein fuel leaking from the fuel chamber flows through the joint into the Venturi mixing tube of the round burner. 
     
     
         14 . The gas burner assembly of  claim 11 , wherein the bottom plate is screwed, riveted or staked to the burner base. 
     
     
         15 . The gas burner assembly of  claim 14 , wherein the bottom plate has a perimeter, the bottom plate mounted to the burner base at the perimeter of the bottom plate. 
     
     
         16 . The gas burner assembly of  claim 11 , wherein the burner base and the bottom plate are formed with discrete material. 
     
     
         17 . The gas burner assembly of  claim 16 , wherein the burner base and the bottom plate are discrete pieces of aluminum alloy. 
     
     
         18 . The gas burner assembly of  claim 11 , wherein the bottom plate defines a Venturi mixing tube of the elongated burner. 
     
     
         19 . The gas burner assembly of  claim 11 , wherein the elongated burner extends between a first end portion and a second end portion, the round burner positioned between the first and second end portions of the elongated burner, the elongated burner having flame ports at the first and second end portions of the elongated burner.
