Gas burner head

Abstract

A gas burner head assembly characterized by a flame-leading pipe strategically positioned between a burning plate and an igniter to provide a climbing path for the flame. The igniter is a part of a standard gas oven and has a fixed height. The burning plate rests on top of a housing that confines a gas-air mixing chamber. The upper open end of the flame-leading pipe is secured on an upper rim of a peripheral wall of the housing. The lower open end of the flame-leading pipe is aligned to the igniter and the main gas nozzle of a valve module mounted on the oven body. By leading the ignited flame to climb from a lower level located by the igniter to a higher level positioned by the burning plate, the gas burner head effectively eliminates the undesirable ignition obstruction while accommodating the standard gas oven valve assembly and igniter.

1 . A burner head assembly, comprising: 
 a housing confining a chamber to accommodate a gas-air mixture, said housing having an open top and an upper rim;    a burning plate located on said open top of said housing for performing radiation and emission of heat;    a gas mixing pipe secured on and penetrating to a vertical wall of said housing, wherein    said gas mixing pipe is positioned to receive a gas nozzle, and wherein    said gas mixing pipe serves as a communication passage of said gas-air mixture between said chamber and said gas nozzle; and    a flame-leading pipe having an upper open end and a lower open end for providing a climbing path that leads an ignited flame to climb from a lower place, where said flame is ignited by a fixed igniter, upward to said upper open end, which is located at a level slightly higher than said burning plate, wherein    said upper open end is securely attached to said rim, and wherein    said lower open end is configured and positioned to align with said ignited flame.    
     
     
         2 . The burner head assembly of  claim 1 , wherein said burner head is an infrared gas burner head.  
     
     
         3 . The burner head assembly of  claim 1 , wherein said flame-leading pipe is a curved hollow pipe and wherein said upper open end has a straight portion.  
     
     
         4 . The burner head assembly of  claim 1 , wherein said flame-leading pipe is an arc-shaped pipe without a straight portion.  
     
     
         5 . The burner head assembly of  claim 1 , wherein said upper open end is securely attached to said rim by welding.  
     
     
         6 . The burner head assembly of  claim 1 , wherein said upper open end is securely attached to said rim with a fastener.  
     
     
         7 . The burner head assembly of  claim 1 , further comprising a brace affixed to a bottom surface of said housing, said brace supporting said lower open end of said flame-leading pipe.  
     
     
         8 . The burner head assembly of  claim 1 , further comprising a heat-proof mesh covering said burning plate.  
     
     
         9 . The burner head assembly of  claim 1 , wherein said housing is a rectangular shaped case.  
     
     
         10 . The burner head assembly of  claim 1 , wherein said flame-leading pipe is formed by joining two straight pipes.  
     
     
         11 . An infrared gas burner head assembly, comprising: 
 a housing confining a chamber to accommodate a gas-air mixture, said housing having an open top and an upper rim;    a burning plate located on said open top of said housing for performing radiation and emission of heat;    a gas mixing pipe secured on and penetrating to a vertical wall of said housing, wherein    said gas mixing pipe is positioned to receive a gas nozzle, and wherein    said gas mixing pipe serves as a communication passage of said gas-air mixture between said chamber and said gas nozzle; and    a flame-leading pipe having an upper open end and a lower open end for providing a climbing path that leads an ignited flame to climb from a lower place, where said flame is ignited by a fixed igniter, upward to said upper open end, which is located at a level slightly higher than said burning plate, wherein    said upper open end is securely attached to said rim, and wherein    said lower open end is configured and positioned to align with said ignited flame.    
     
     
         12 . The infrared gas burner head assembly of  claim 11 , wherein said upper open end has a straight portion.  
     
     
         13 . The infrared gas burner head assembly of  claim 11 , wherein said flame-leading pipe has a curved, arc, or angular shape.  
     
     
         14 . The infrared gas burner head assembly of  claim 11 , wherein said upper open end is securely attached to said rim by welding or with a fastener.  
     
     
         15 . The infrared gas burner head assembly of  claim 11 , further comprising a holding means for supporting said lower open end of said flame-leading pipe, wherein said holding means is attached to a bottom surface of said housing.  
     
     
         16 . The infrared gas burner head assembly of  claim 11 , further comprising a heat-proof mesh covering said burning plate.  
     
     
         17 . The infrared gas burner head assembly of  claim 16 , wherein said mesh is attached to said rim.  
     
     
         18 . The infrared gas burner head assembly of  claim 11 , wherein said flame-leading pipe is formed by joining straight pipes.
