Description
- Not Applicable.
- The present invention relates in general to cooking assemblies, and more particularly, to a gas burner apparatus and the method for providing both a high burning rate of such apparatus when needed and maintaining stable flame conditions when the burning rate of such apparatus is reduced.
- In conventional gas cooking appliances, a plurality of gas burners are arranged in an array on a gas cook top. A manifold connects the plurality of gas burners to a source of gas fuel and the valves on the manifolds allows the user to adjust the flow of gas to the burners. Typically, gas burners are annular or circular in shape. There are also flame-generating ports disposed around the burner to provide a ring of burning flames emanating from the ports when the user adjusts the flow of gas to the burner. However, conventional gas burners fail to provide a wide range of heating capability, for example, from high burning rates with low-time-to-boil to low burning rates with simmering capability. Thus, a user who wants to run at high burning rates to cook food as quickly as possible may not be able to turn the burner down low enough to keep the burner at a consistent burning rate for simmering food. The lower burning rate will also save fuel if the user decides to keep the burner running so that there will be no heat up delay when the burner is restarted. Therefore, a need exists for a burner apparatus that allows users to maintain a low burning rate and more consistent burning flames without the need to completely turn off the burner and the ability to run at a high burning rate to cook the food when needed.
- The present invention provides an apparatus and a method for maintaining stable flame conditions of a gas burner without sacrificing the burning rate at the top end. In one aspect of the present disclosure, a gas burner apparatus is provided comprising a burner base disposed over a gas burner, a burner head disposed over the burner base, and one or more burner covers disposed over the burner head.
- A gas burner apparatus is disclosed in accordance with one embodiment of the present disclosure. A gas burner apparatus comprising a burner base disposed over a gas burner, a burner head disposed over the burner hot plate base and one or more burner covers slidably disposed over the burner head.
- A method for maintaining stable burning flames of a gas burner is also disclosed. The method comprises providing a burner base over a gas burner, providing a burner head with one or more burner ports over the burner base, providing one or more burner covers over the burner head, and sliding the one or more burner covers over at least one of the one or more burner ports.
- The following description and drawings set forth in detail a number of illustrative embodiments of the invention. These embodiments are indicative of but a few of the various ways in which the present invention may be utilized.
- A more complete appreciation of the present invention is provided by reference to the following detailed description of the appended drawings and figures.
