Flame hole unit structure of a gas burner

Abstract

A gas burner for simplifying assembling and manufacturing of a burner flame hole unit by overlapping plates. Portions of the plates are cut so that the cut portions communicate with each other. Flame holes and mixture channels for a mixture of gas and air pass through a gap between the cut portions. The cut portions overlap and communicate with each other between adjacent plates, thereby forming flame holes and channels for flow of the mixture of gas and air through gaps between the cut portions.

1 . A gas burner having a plurality of inlets and a plurality of flame holes through which a mixture of a gas and air is injected and at which flames are supported, the gas burner comprising at least two overlapping cut plates, each cut plate having a plurality of cutout portions extending from a respective edge of the cut plate, wherein
 the cutout portions of adjacent cut plates partially overlap each other for continuous flow of a gas mixture, and   the cutout portions include gaps at respective edges of the plates, the gaps defining the inlets for the gas mixture and the flame holes for supporting flames.   
     
     
         2 . The structure according to  claim 1 , comprising sets of overlapping cut plates, each set of overlapping cut plates including
 an inner cut plate having cutouts and having gaps at an upper edge, and   outer cut plates overlapping opposite sides of the inner cut plate and having cutouts and having gaps at lower edges, the cutouts in the inner plate corresponding to and in fluid communication with the cutouts in the inner cut plate.   
     
     
         3 . The structure according to  claim 2 , including fixing plates overlapping opposite sides of each set of cut plates, wherein the flame holes are disposed at a uniform interval. 
     
     
         4 . The structure according to  claim 1 , wherein each flame hole has a rectangular cross-sectional shape. 
     
     
         5 . The structure according to  claim 2 , wherein each flame hole has a rectangular cross-sectional shape. 
     
     
         6 . The structure according to  claim 3 , wherein each flame hole has a rectangular cross-sectional shape.
