Burner for gas cooking units

A gas cooking apparatus, comprising:

• a hollow body having a lid;
• and
• a burner unit within the hollow body, the unit including an upwardly concave, disk-shaped member having a center, a bottom and a central protrusion in the bottom, and a manifold having a top with a circular opening and an interior mounting surface within the opening, the disk-shaped member being connected to the manifold within the opening, the protrusion of the disk-shaped member being against the mounting surface, a circular gap extending about the disk-shaped member between the member and the manifold, a drainage passageway extending through the disk-shaped member and the manifold adjacent to the center of the disk-shaped member, the manifold having a gas connection located radially outwards from the disk-shaped member and an opening for air adjacent the connection, whereby air mixes with gas entering the manifold through the connection and an air/gas mixture passes through the gap between the manifold and the disk-shaped member.

A burner unit for a gas cooking apparatus, the unit comprising:

• an upwardly concave, disk-shaped member having a center, a bottom and a drainage passageway extending through the center;
• and
• a manifold having a top with a circular opening, the disk-shaped member being connected to the manifold within the opening by a fastener at the center of the disk-shaped member, a circular gap extending about the disk-shaped member between the member and the manifold, the manifold having a drainage passageway aligned with the passageway in the disk-shaped member, the passageway extending through the fastener, and a gas connection located radially outwards from the disk-shaped member, and an opening for air adjacent the connection, whereby air mixes with gas entering the manifold through the opening and an air/gas mixture passes through the gap between the manifold and the disk-shaped member.

A burner unit as claimed in claimed 7, wherein the fastener is a pair of complementary threaded collars.

A burner unit for a gas cooking apparatus, the unit comprising:

• an upwardly concave, disk-shaped member having a bottom, a central protrusion on the bottom and a plurality of projections extending about the protrusion;
• and
• a manifold having a top with a circular opening and an interior mounting surface within the opening, the protrusion on the disk-shaped member being against the mounting surface, the projections of the disk-shaped member contacting the manifold about the opening, the disk-shaped member being connected to the manifold within the opening, a circular gap extending about the disk-shaped member between the member and the manifold, the manifold having a gas connection located radially outwards from the disk-shaped member, and an opening for air adjacent the connection, whereby air mixes with gas entering the manifold through the opening and an air/gas mixture passes through the gap between the manifold and the disk-shaped member.
