Grate to improve the simmering on a gas hob

Abstract

Gas burner assemblies include a cooking gas hob and a grate for supporting cooking utensils. The grate includes a plate which integrates a protection for preventing the flame of a burner from being extinguished from a wind blow when operating around the minimum level. Simmering performance of such burner assembly is enhanced.

1 . A gas burner assembly comprising:
 a cooking gas hob having a gas burner which feeds combustible gas to a flame;   a grate positioned above the gas burner; and   a plate secured to the grate and presenting a surface above the burner,   wherein the plate is displaced a predetermined distance from the gas burner so as to retain the flame of the gas burner below the grate when the burner is operated near the minimum level   
   
   
       2 . The gas burner assembly according to  claim 1 , wherein the plate is integral with the grate. 
   
   
       3 . The gas burner assembly according to  claim 1 , wherein the plate is flat and parallel with a worktop in which the hob is installed. 
   
   
       4 . The gas burner assembly according to  claim 1 , wherein the plate and the grate are formed by a metal casting process. 
   
   
       5 . The method for preventing the extinguishing of a gas burner flame from accidental air blows in a cooking gas hob according to  claim 1 , wherein the method comprises the step of setting the burner to operate to a predetermined minimum power level retaining the flame underneath the plate.
