Abstract
A gas burner for a cooking appliance includes a frustoconically-shaped crown having a plurality of gas ports defined therein, a cover positioned above the crown, and a shell secured to the cover and positioned on the crown. The shell defines a hollow chamber positioned between the crown and the cover.
Claims14
A gas burner for a cooktop comprising:
- a frustoconically-shaped crown attached to a circular base having a vertical annular surface and includes an inclined annular surface, the crown having a plurality of gas ports defined therein;
- a cover positioned above the crown;
- a shell having a first inclined surface, the shell secured to the cover and positioned on the crown, the shell defining a hollow chamber positioned between the crown and the cover, wherein the shell includes a waist where the first inclined surface intersects with a second inclined surface, the crown includes a rim, and a diameter of the waist is less than a diameter of the rim of the crown;
- a first imaginary line extends along the inclined annular surface;
- and
- a second imaginary line extends along the vertical annular surface and a third imaginary line extends along the first inclined surface, wherein an angle is defined between the first imaginary line and the second imaginary line;
- and wherein the third imaginary line is coincident with the first imaginary line.

A gas burner for a cooktop comprising:
- a cap having a hollow chamber defined therein, said cap comprising a first inclined surface;
- said cap further comprising:
- a shell having said first inclined surface, the shell secured to a cover and positioned on a crown, the shell defining a hollow chamber positioned between the crown and the cover, wherein the shell includes a waist where the first inclined surface intersects with a second inclined surface, the crown includes a rim, and a diameter of the waist is less than a diameter of the rim of the crown;
- and
- the crown having a plurality of gas ports defined therein, the crown having an inclined annular surface and a vertical annular surface, wherein
- (i) a first imaginary line extends along the inclined annular surface, a second imaginary line extends along the vertical annular surface and a third imaginary line extends along the first inclined surface;
- (ii) an angle is defined between the inclined annular surface and the vertical annular surface, wherein the third imaginary line is coincident with the first imaginary line, and
- (iii) the magnitude of the angle is between 30 degrees and 45 degrees.
