DIFFUSION PLATE AND GRATE ASSEMBLY FOR A GAS BURNER

摘要

A gas burner and grate combination includes a gas burner constructed for bei ng operated at least at a high intensity level and at a low intensity level. A grate is located relative to the gas burner for supporting a cooking utensil thereon. A diffusion burner plate is located above the gas burner spaced from a cooking utensil when a cooking utensil is positioned on the grate. The diffusion burner plate is of a size such that when the gas burner is operated at a high intensity level the flame length is lon g enough to reach beyond the edges of the diffusion burner plate, and when the gas burne r is operated at a low intensity level, the flame is contained under the diffusion burner plate such that heating of the cooking utensil occurs by radiation. In a further aspect, a cooktop includes the described gas burner and grate combination.
