TECHNICAL FIELDThe present disclosure is generally related to outdoor cooking grills and, more particularly, is related to an apparatus and method for providing an improved cooking grate for an outdoor cooking grill.
BACKGROUNDOutdoor cooking grills are popular for many reasons including enhanced food flavor and enjoyment of the outdoor cooking process. Gas-fired cooking grills are popular for home use and differ from traditional barbecue grills in that they rely upon a gas flame for heat energy, as opposed to the combustion of charcoal briquettes or the like. Conventional burner gas grills frequently utilize tubular burners having multiple combustion ports or orifices. The grills often employ an inert material, such as so-called “lava rocks” or ceramic tiles, to absorb drippings from food cooking on a grate positioned above the material and to radiate heat for providing a more even heat distribution. Infrared burner gas grills provide a generally planar heat source where the combustion occurs at or near the surface of a ceramic or fiber element. The planar configuration of infrared burners reduces or eliminates the need for the inert material with respect to heat distribution.
A disadvantage with such grills is that food drippings, such as liquefied greases and oils, that come into contact with gas flames or other heat sources during cooking cause flash flames or “flare-ups,” which can result in the charring of the food product being grilled. Although vaporization of the food drippings is desirable because the vapors enhance the flavor of food cooked on a grill, the flare-ups frequently associated with the food drippings can be detrimental to the resulting quality of grilled food. One attempted solution to the problem of flare-ups includes U.S. Pat. No. 5,355,780 to Campbell, which discloses a grate for a cooking grill that utilizes the spacing between the rails to prevent flames from passing through the spaces. Another device, disclosed in U.S. Pat. No. 5,735,260, utilizes one or more tiles positioned between the heat source and the cooking surface. The tiles include channels for allowing food drippings to flow through to the heat source. Similarly, U.S. Pat. No. 6,114,666 utilizes a ceramic infrared radiant energy emitter that is positioned above the heat source. The emitter re-radiates thermal energy that is absorbed from the burner below. Other devices, such as disclosed in U.S. Pat. No. 5,911,812, utilize fluid channels to direct the food drippings away from the hottest section of the cooking grill. Still other devices, such as disclosed in U.S. Pat. No. 6,314,870 utilize various forms of drip pans placed between the item being cooked and the heat source. In some cases, the above described devices require additional grill structural features for proper implementation. For example, the tiles of the '260 patent and the emitter of the '666 patent require a support structure between the heat source and the cooking grate. Similarly, other of the devices reduce the flavor of the cooked food by completely eliminating or reducing the favorable impact of the food drippings. Thus, a heretofore unaddressed need exists in the industry to address the aforementioned deficiencies and inadequacies.
SUMMARYBriefly described, one embodiment, among others, can be implemented as a cooking grate for improving cooking performance on an outdoor cooking grill, comprising: a metallic plate configured to be placed over a heat source in the outdoor cooking grill, the metallic plate having a plurality of perforation holes; and a plurality of cooking surface ribs configured to support food during cooking and positioned above the metallic plate.
Embodiments of the present disclosure can also be viewed as providing methods of providing an improved cooking grate for an outdoor cooking grill comprising: perforating a metallic plate, configured to be positioned above a heat source on the outdoor cooking grill; forming a plurality of cooking surface ribs, configured to be received by the plurality of cooking rib supports and positioned above the metallic plate; and assembling a cooking grate by attaching the plurality of cooking rib supports to the metallic plate utilizing the plurality of cooking rib supports.
Embodiments of the present disclosure can also be viewed as providing an apparatus for improving cooking performance on an outdoor cooking grill, comprising: a grate bar assembly, configured to support food on the outdoor grill; a grate housing, configured to receive the grate bar assembly; a first end cap, attached to the grate housing; and a second end cap, attached to the grate housing.
Embodiments of the present disclosure can also be viewed as providing a cooking grill, comprising: a housing having a cavity; a heat source mounted within the cavity of the housing; and a cooking surface, supported in the housing at a position above the heat source. The cooking surface comprises a perforated plate and a plurality of cooking surface ribs positioned above the perforated plate.
Other systems, methods, features, and advantages of the present disclosure will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the present disclosure, and be protected by the accompanying claims.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Having summarized various aspects of the present disclosure, reference will now be made in detail to the description of the disclosure as illustrated in the drawings. While the disclosure will be described in connection with these drawings, there is no intent to limit it to the embodiment or embodiments disclosed herein. On the contrary, the intent is to cover all alternatives, modifications and equivalents included within the spirit and scope of the disclosure as defined by the appended claims.
Reference is now made to
The cooking grill 100 includes a cooking grate 108 positioned above the heat source 104 and supported within the cavity 103 by cooking grate supports 110. One of ordinary skill in the art will appreciate that the cooking grate supports 110 can be configured as separately attached members or integrally formed into the grill housing 102. Further, the grill supports 110 can be configured as multiple distinct points of support around the periphery of the grill housing 102 or as a supporting surface, such as a lip or ledge, integrally formed in the grill housing 102.

The metallic plate 124 also includes multiple perforation holes 125. During cooking, the perforation holes 125 are configured to allow a portion of the liquid drippings from the food to drop to the heat source. As the drippings are vaporized by the heat source, the flavor of the food is enhanced by the resulting vapors. Additionally, the remaining portion of the drippings are vaporized by the elevated temperature of the metallic plate 124. Further, the configuration of the perforations reduces the flow of air from the cavity 103 and thus to the spaces between the ribs 122, which reduces or eliminates requisite combustion air for grill flare-ups. In the embodiment shown in
Alternative embodiments of the cooking grate can be configured without the rib mounts 120. For example, the cooking surface ribs 122 can be directly attached to the metallic plate 124 through any of the mechanical fastening techniques discussed above. Alternatively, the cooking surface ribs 122 may be supported by a structural component in the grill housing (not shown). An exemplary structural component for supporting the cooking surface ribs 122 can include a ledge or lip feature attached to or integrated into the grill housing, among others. Similarly, although the cooking surface ribs are illustrated as substantially parallel, other cooking surface rib arrangements are consistent within the scope and spirit of this disclosure.
