    摘要: In one aspect the invention discloses a gas cooktop which is relatively easy to clean and which is not visually complex. The gas cooktop surface is provided with a trivet having two operating conditions. In a first condition the trivet is retracted and is substantially flush with the cooktop surface. In a second condition the trivet is extended to support a cooking vessel above a gas burner. In another aspect the invention discloses an improved gas burner with a high turn-down ratio. The improved burner includes first and second gas flow passages, a flame front locator, in one of the passages and a burner head. Fuel gas is injected into an end of one of said passages and is ignited to establish a flame at the flame front locator. Secondary combustion air is provided through the other of the passages which on a high setting enables secondary combustion and on a low setting may mix with the hot gases and cool them resulting in a lower temperature at the cooking vessel.

    摘要: In one aspect the invention discloses an improved gas burner with a high turn-down ratio. The improved burner includes first and second gas flow passages (44, 47), a flame front locator (49) in one of the passages of the burner head. Fuel gas is injected into an end of one of one of the passages (47) and is ignited to establish a flame at the flame front locator (49). Secondary combustion air is provided through the other of the passages (44) which on a high setting enables secondary combustion and on a low setting may mix with the hot gases and cool them resulting in a lower temperature at the cooking vessel.
