Gas burner assembly for a gas cooking appliance
Field of the Invention The present invention relates to a gas burner assembly for a gas
cooking appliance, in particular for a gas cooking hob. Further,
the present invention relates to a gas cooking appliance includ
ing at least one gas burner assembly. Moreover, the present in
vention relates to a gas cooking hob, including at least one gas
burner assembly.
Background of the Invention Any reference herein to known prior art does not, unless the
contrary indication appears, constitute an admission that such
prior art is commonly known by those skilled in the art to which
the invention relates, at the priority date of this application.
In a gas burner assembly with an atmospheric aeration usually
the air and gas are mixed by a Venturi tube in a primary aera
tion phase. For the primary aeration phase about 60 % of air is
required. A gas jet drags the air into a Venturi tube. The air
and gas are mixed in a convex zone of the Venturi tube and com
pleted in a throat of said Venturi tube. In conventional gas
burner assemblies the primary air is fed either from the bottom
or the top of the gas cooking appliance.
Current gas burner assemblies comprise a burner body, a burner
crown, a burner cap and an external Venturi tube. In order to
improve the efficiency of a gas cooking appliance, the distance
between the gas burner assembly and a pan or pot is continuously
reduced. However, this leads to a centralized temperature dis
tribution.
