Abstract
Simmer performance in gas ranges is improved by providing a burner grate with a flame impingement ring centered over the gas burner. The burner grate includes a base and a plurality of fingers attached to the base. The flame impingement ring is attached to all or some of the fingers. The flame impingement ring is sized so that simmer flames from the gas burner will impinge thereon. Thus, the flames are directed away from direct impingement on the cooking utensil, and some heat from the flames is absorbed by the grate. The flame impingement ring can have many cross-sectional configurations including curved, circular, oval or straight.
Claims15
A burner grate comprising:
- a base having a center point;
- a plurality of fingers having proximal ends attached to said base, and distal ends spaced radially inwardly from said base adjacent to said center point;
- and
- a flame impingement ring attached to at least some of said plurality of fingers coaxially with said center point, and including an inner rim defining an opening around said center point, and an outer rim disposed at said finger distal ends so that a burner flame may be selectively directed in impingement against said ring during simmer operation and directed radially outwardly of said ring during operation above simmer.
A burner grate for a range having at least one gas burner, said burner grate comprising:
- a base having a center point;
- a plurality of fingers having proximal ends attached to said base, and distal ends spaced radially inwardly from said base adjacent to said center point;
- and
- a flame impingement ring attached to at least some of said plurality of fingers coaxially with said center point, and including an inner rim defining an opening around said center point, and an outer rim disposed at said finger distal ends so that a burner flame may be selectively directed in impingement against said ring during simmer operation, and directed radially outwardly of said ring during operation above simmer.
A gas range comprising:
- at least one gas burner;
- a burner grate situated coaxially over said gas burner, said burner grate comprising:
- a base having a center point;
- a plurality of fingers having proximal ends attached to said base, and distal ends spaced radially inwardly from said base adjacent to said center point;
- and
- a flame impingement ring attached to at least some of said plurality of fingers coaxially with said center point, and including an inner rim defining an opening around said center point, and an outer rim disposed at said finger distal ends so that a burner flame may be selectively directed in impingement against said ring during simmer operation, and directed radially outwardly of said ring during operation above simmer.
