Patent ID: 8887710

Claim:
A cooking gas burner assembly including a distributor ( 30 ), a gas manifold ( 50 ) and a cup ( 40 ), said gas manifold ( 50 ) including at least one gas inlet and a plurality of gas outlets to deliver supply gas to said distributor ( 30 ), said cup ( 40 ) being in contact with a hob ( 141 ) of a cooking appliance and located between said gas manifold ( 50 ) and said distributor ( 30 ), wherein said gas manifold ( 50 ) is spaced from said cup ( 40 ) by at least one post ( 70 , 72 , 74 ) extending vertically between said manifold ( 50 ) and said cup ( 40 ), and wherein the cup ( 40 ) forms a shield between the manifold ( 50 ) and the distributor ( 30 ) that reduces conductive heat transfer from the distributor ( 30 ) to the manifold ( 50 ); wherein said distributor ( 30 ) includes downwardly extending spigots ( 32 ) to engage said cup ( 40 ), each spigot ( 32 ) defined by a truncated conical geometry with a sidewall and an end surface; wherein said cup ( 40 ) includes a plurality of discrete, enclosed concave recesses ( 48 ) that each receive one of said spigots ( 32 ), wherein the enclosed recesses ( 48 ) are elliptical in cross section and each enclosed recess ( 48 ) having two surfaces is defined by an interior sidewall surface and a base surface that supports the end surface of the spigot ( 32 ); wherein the sidewall of the spigot ( 32 ) is provided at a first angle relative to the base surface and the sidewall surface of the enclosed recess ( 48 ) is provided at a second angle relative to the base surface that is different from the first angle so that as said distributor ( 30 ) changes dimensions during use due to thermal expansion, limiting contact between the sidewall of the spigot ( 32 ) and the sidewall surface of the enclosed recess ( 48 ) due to the difference between the first and second angles; and wherein said enclosed recess ( 48 ) has an elongated shape.
