Description
- The present subject matter relates generally to burner assemblies, such as burner assemblies for range appliances.
- Range appliances generally include a cooktop portion and an oven portion. The cooktop portion of certain range appliances includes a griddle burner for heating large cookware, such as griddles and fish poachers. Griddle burners provide flame ports along a length of the griddle burner in order to more uniformly or evenly heat large cookware on the cooktop portion. However, griddle burners have certain drawbacks. For example, heating smaller cookware, such as round pots, with griddle burners can be inconvenient and/or difficult. Thus, griddle burners may consume a large surface area of an associated range appliance despite having limited cooking utility.
- Certain griddle burners include features for assisting heating of cookware smaller than griddles. Partitioned griddle burners permit independent operation of discrete sections of the griddle burner. Thus, a user may operate a single section of the griddle burner in order to heat a small pot or may operate all the sections to heat a griddle. However, partitioned griddle burners can be expensive to manufacture, difficult to operate and may not heat smaller cookware uniformity due to the asymmetrical distribution of flame ports within the griddle burner sections.
