Benefits of technology
The present invention provides an oven appliance with a cooking chamber that includes a top wall and a bottom wall, as well as an air handler to circulate heated gas. The oven appliance also includes a convection duct and a radiant heating element. The air handler is in communication with the convection duct to supply heated gas to the cooking chamber through the convection duct. The radiant heating element is positioned proximate to the top wall of the cooking chamber. This design enables the oven appliance to cook items quickly and evenly using both convection and radiant heating.
Problems solved by technology
Oftentimes, these conventional appliances are unable to provide an even or desirable heat distribution above the food item being cooked.
For example, the broiler element may be unable to evenly heat the predefined heating surface.
In turn, radiation from the predefined heating surface may heat or cook items in an undesirable or uneven manner.
Such appliances are unable to quickly transition from baking to broiling, and vice versa.
For example, only one gas burner can be ignited at a given time because simultaneous burner operation may result in poor combustion.
In such systems, transitioning between bake and broil can require significant time since one burner (e.g., the bake burner) needs to be turned off and then the other (e.g., the broil burner) ignited.
Moreover, in conventional appliances, the broiler element may require a significant amount of pre-heating time before a suitable broiler temperature is reached.
This additional pre-heating time may frustrate a user and / or hinder cooking operations.

An oven appliance includes a cabinet defining a cooking chamber to receive items to be cooked. The cooking chamber includes a top wall, a bottom wall, a rear wall, and opposing sidewalls. The top wall and the bottom wall are spaced apart along a vertical direction. The opposing sidewalls are spaced apart along a lateral direction. The oven appliance also includes a broiler assembly. The broiler assembly includes a convection heating element and a radiant heating element. The convection heating element is disposed outside of the cooking chamber and in convective communication with the cooking chamber to supply heated gas to the cooking chamber. The radiant heating element is disposed in the cooking chamber proximate the top wall of the cooking chamber.
Description
FIELD OF THE INVENTION[0001]The present subject matter relates generally to oven appliances, and more particularly to oven appliances having combined convection and radiant heating features.BACKGROUND OF THE INVENTION[0002]Conventional residential and commercial oven appliances generally include a cabinet that defines a cooking chamber for receipt of food items for cooking. Heating elements are positioned within the cooking chamber to provide heat to food items located therein. The heating elements can include, for example a bake heating assembly positioned at a bottom of the cooking chamber and / or a broiler heating assembly positioned at a top of the cooking chamber. Typical broiler heating assemblies include one or the other of a radiant heating element or a convection heating element, but not both.[0003]Some conventional appliances include a broiler assembly that uses a burner or electric heating element directed toward a predefined heating surface. During use, the burner or elec...
