Combination gas burner assembly

Abstract

A combination gas burner assembly includes a first burner forming a first profile shape and a second burner positioned above the first burner. The second burner forms a second profile shape different from the first profile shape. The first burner and the second burner form a perimeter of the gas burner assembly. The first profile shape overlaps with the second profile shape forming an overlapping portion of the perimeter.

         2 . The burner assembly according to  claim 1 , wherein the at least one turn limits a velocity of the fuel output via the first ignition port. 
     
     
         3 . The burner assembly according to  claim 1 , wherein the passage is formed on a bottom surface of the first spreader. 
     
     
         4 . The burner assembly according to  claim 1 , wherein the first spreader comprises a receiving arc terminal formed on the bottom surface along a first perimeter of the first spreader and proximate to the first ignition port, wherein the arc terminal is spaced over a spark gap from the igniter. 
     
     
         5 . The burner assembly according to  claim 1 , wherein the passage comprises a recessed passage and the at least one turn forms a tortuous path comprising a plurality of switchback turns. 
     
     
         6 . The burner assembly according to  claim 5 , wherein the tortuous path comprises a chamber labyrinth extending from the supply aperture to the supply port. 
     
     
         7 . The burner assembly according to  claim 1 , wherein the passage comprises at least one intermediate barrier wall forming the at least one turn. 
     
     
         8 . The burner assembly according to  claim 1 , wherein the at least one burner comprises a first burner comprising the first spreader and a second burner comprising a second spreader, wherein the second spreader is in fluid communication with the fluid supply. 
     
     
         9 . The burner assembly according to  claim 8 , wherein the second burner is stacked over the first burner and the second spreader of the second burner comprises a second ignition port position below the first ignition port and proximate to the igniter. 
     
     
         10 . The burner assembly according to  claim 9 , wherein the second ignition port extends from an interior cavity formed between a burner cap of the second burner and the second spreader, wherein the burner cap is interposed between the first burner and the second burner. 
     
     
         11 . The burner assembly according to  claim 9 , wherein the first spreader forms a first perimeter comprising a plurality of first burner ports and the second spreader forms a second perimeter comprising a plurality of second burner ports, wherein a portion of each of the first perimeter and the second perimeter extend proximate the igniter. 
     
     
         12 . The burner assembly according to  claim 11 , wherein the second perimeter forms a shared ignition aperture extending from the igniter to the first ignition port and the second ignition port. 
     
     
         13 . A method for delivering fuel to a burner assembly of an appliance, the method comprising:
 receiving the fuel from a supply port from a fuel supply;   communicating the fuel supply to a first spreader of at least one burner of the burner assembly; and   communicating the fuel through a passage of the first spreader comprising a plurality of turns and extending from the supply port to a first ignition port, wherein a velocity of the fuel is controlled through the passage by navigating the plurality of turns.   
     
     
         14 . The method according to  claim 13 , wherein the plurality of turns comprise a plurality of switchback turns formed by intermediate barrier walls and extend along a tortuous path. 
     
     
         15 . The method according to  claim 13 , wherein the at least one burner comprises a first burner and a second burner, the first burner comprising the first spreader, the method further comprising:
 supplying the fuel from the supply port to a second spreader of the second burner, wherein the fuel supplied to the first spreader is communicated through the second spreader.   
     
     
         16 . The method according to  claim 15 , wherein the fuel supplied to the second spreader is communicated through a second ignition port formed below the first ignition port. 
     
     
         17 . The method according to  claim 16 , further comprising:
 supplying the fuel from the first ignition port and the second ignition port to a shared ignition aperture forming a portion of a perimeter of the second burner between the second ignition port and an igniter of the burner assembly.   
     
     
         18 . The method according to  claim 16 , further comprising:
 controlling the igniter to output an ignition spark extending over a spark gap between the igniter and an arc terminal formed on the first spreader.   
     
     
         19 . A burner assembly comprising:
 an igniter;   a first burner comprising a first spreader having a first ignition port in fluid communication with a fuel supply and proximate the igniter;   a second burner comprising a second spreader having a second ignition port in fluid communication with a fuel supply and proximate the igniter, wherein the first burner is positioned above the second burner in a stacked configuration;   wherein the first ignition port extends from a passage formed through a portion for the first spreader extending from a supply aperture in fluid communication with the fuel supply; and   wherein the passage comprises a plurality of turns between the supply aperture and the first ignition port, wherein the at least one turn limits a velocity of the fuel output via the first ignition port.   
     
     
         20 . The burner assembly according to  claim 19 , wherein the second ignition port extends from an interior cavity formed between a burner cap of the second burner and the second spreader; and the first burner port and the second burner port outlet to a shared ignition aperture formed along a perimeter of the second spreader.
