Flame Flashback Resistant Gas Burner

Abstract

A gas burner includes: a base having a bottom wall and a surrounding wall that extends upwardly from the bottom wall, that cooperates with the bottom wall to define an inner space, and that is formed with flame apertures in fluid communication with the inner space; a partitioning unit dividing the inner space into a main gas chamber and at least one buffer gas chamber separated from the main gas chamber, the partitioning wall being formed with through-holes that are in fluid communication with the main gas chamber and the buffer gas chamber and that open toward the bottom wall of the base; and a gas input conduit secured to the bottom wall of the base and in fluid communication with the main gas chamber.

1 . A gas burner comprising:
 a base having a bottom wall and a surrounding wall that extends upwardly from said bottom wall, that cooperates with said bottom wall to define an inner space therein, and that is formed with a plurality of flame apertures in fluid communication with said inner space and the atmosphere, said surrounding wall having a top opening;   a partitioning unit dividing said inner space into a main gas chamber and at least one buffer gas chamber separated from said main gas chamber, said partitioning unit being formed with a plurality of through-holes that are in fluid communication with said main gas chamber and said buffer gas chamber and that open toward said bottom wall of said base;   a cover covering said top opening of said surrounding wall of said base; and   a gas input conduit secured to said bottom wall of said base and in fluid communication with said main gas chamber.   
   
   
       2 . The gas burner as claimed in  claim 1 , wherein said partitioning unit includes a partitioning wall having a vertical wall portion that is disposed adjacent to and that confronts said flame apertures in said surrounding wall, and a horizontal wall portion that is transverse relative to said vertical wall portion and that is disposed adjacent to and that confronts said bottom wall, said through-holes being formed in said partitioning wall. 
   
   
       3 . The gas burner as claimed in  claim 2 , wherein said vertical and horizontal wall portions of said partitioning wall are substantially and respectively parallel to said surrounding wall and said bottom wall. 
   
   
       4 . The gas burner as claimed in  claim 3 , wherein said buffer gas chamber has an L-shaped cross-section.
