Benefits of technology

[0014]Further, one or more types of outlet openings are also preferably provided for the rib elements so that hot gas generated by the burner or other heating element does not simply remain stagnant in the interior of the rib elements but continuously flows through and out of the rib elements. This increases and accelerates the heat transfer to the rib elements which greatly reduces the required preheating time and increases the contacting temperature of the rib elements to provide beneficial searing and to produce attractive grill marks. It also increases thermal efficiency and increases the infrared percentage of total cooking energy.

Problems solved by technology

many existing infrared systems, including, but not limited to, those having open grates positioned above an intermediate infrared emitting plate or other structure, are commonly prone to flare-up problems caused by the ignition of fat which drips from the food product; and
cooking grate structures heretofore developed in the art to reduce flare-ups have also had significant shortcomings or deficiencies in that, for example: (a) they can require extended preheat times; (b) the food contacting portions of the grate do not heat quickly enough and / or do not reach a sufficient temperature for adequately searing the food product and / or for providing attractive grill marks on the product; and / or (c) the grate structures can be difficult and expensive to make due to the need to hold tight tolerances and the difficulty of applying porcelain coatings to small openings.

embodiment 100

[0074]An alternative embodiment 100 of the inventive grate assembly is illustrated in FIG. 4. Except for the differences discussed below, the construction, features, materials, and other particulars of the inventive grate assembly 100 will preferably be the same as inventive assembly 2 and / or inventive assembly 50 and these features will provide all of the same benefits and advantages discussed above.

[0075]The inventive grate assembly 100 will preferably be identical to either the inventive grate assembly 2 or the inventive grate assembly 50, or a combination thereof, except that the parallel structures 102 of the lower radiating plate 4 of the assembly 100 have an upwardly curved rather than an inverted V cross-sectional shape.

embodiment 150

[0076]An alternative embodiment 150 of the inventive grate assembly is illustrated in FIG. 5. Except for the differences discussed below, the construction, features, materials, and other particulars of the inventive assembly 150 will preferably be the same as those of the inventive assembly 2 and / or the inventive assembly 50 and these features will therefore provide all of the same benefits and advantages discussed above.

[0077]The inventive grate assembly 150 will preferably be identical to inventive grate assembly 2 or inventive grate assembly 50, or a combination thereof, except that the parallel structures 152 of the lower radiating plate 4 of the grate assembly 150 are flat rather than having an inverted V cross-sectional shape. Consequently, although easier to manufacturer, the rate of fat drainage from the inventive grate assembly 150 will be slower than is provided by inventive assemblies 2 and 50.

embodiment 200

[0078]An alternative embodiment 200 of the inventive grate assembly is illustrated in FIG. 6. Except for the differences discussed below, the construction, features, materials, and other particulars of the inventive assembly 200 will preferably be the same as those of the inventive assembly 2 and / or the inventive assembly 50 and these features will therefore provide all of the same benefits and advantages discussed above.

[0079]The inventive grate assembly 200 will preferably be identical to inventive grate assembly 2 or inventive grate assembly 50, or a combination thereof, except that the parallel structures 202 of the lower radiating plate 4 of the grate assembly 200 have flat top surfaces 204 with downwardly sloping sides 206 which facilitate fat drainage.

Abstract

A cooking grate and a grill assembly having one or more of the cooking grates therein. The cooking grate can be a one-piece structure but is preferably a two-piece structure wherein the upper piece comprises longitudinally extending food support ribs having hollow interiors. The ribs will be positioned over and cover open areas in the lower structure so that combustion gases flowing through the open areas of the lower structure will flow into the hollow interiors of the food support ribs.

Description

RELATED CASE[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 424,308 filed on Dec. 17, 2010, and incorporates said provisional application by reference into this disclosure as if fully set out at this point.FIELD OF THE INVENTION[0002]The present invention relates to cooking grates and grate assemblies which support food items for cooking in outdoor grills and in other cooking systems. The invention also relates to cooking systems which utilize such grates or grate assembliesBACKGROUND OF THE INVENTION[0003]Outdoor grilling systems which primarily utilize infrared radiant energy for cooking food items are known in the art. The beneficial results which these systems are capable of providing over conventional convective grills are also well known. However, there are various shortcomings which are often associated with the current infrared systems. The following are examples of such shortcomings and deficiencies commonly encountered in existi...
