The present invention relates generally to cooking stations and, more specifically, the present invention relates to structure for griddles to resist the effects of thermal stress and strain on such griddles.
Barbequing has become a popular and pervasive tradition in much of the world. A barbeque grill is a device for cooking food by applying heat directly below a grill cooking surface. Another preferred cooking surface is a griddle due to the larger variety of foods one is able to cook over its cooking surface. A griddle is a cooking device having a broad flat cooking surface that is typically heated by being placed directly on a grill or over flame burners and is used in both residential and commercial applications for a variety of cooking operations. Some griddles are also heated using electrical elements. The griddle is most commonly a flat metal plate composed of cast or wrought iron, aluminum or carbon steel.
An issue found with griddles is that over time griddles have a tendency to warp due to the repeated thermal stress and strain placed on the griddle. This issue can be accelerated depending on how the griddle is used when heated at high temperatures. For example, when a hot griddle receives cold food or water on the cooking surface, the metal is cooled quickly at the surface. This causes the metal along the cooking surface to contract more than the metal along the bottom surface of the griddle, typically kept hot over flame burners, for example. These types of uses with the griddle may cause thermal fatigue and cause the griddle to warp.
The present invention is directed to devices, systems and methods for minimizing the effects of thermal stress and thermal strain on a griddle. In one embodiment, a main body and a griddle are provided. The main body extends to define a front side, a rear side, a left side and a right side each extending between a lower end and an upper portion. Further, the main body includes multiple heating elements supported by the main body and coupled to the upper portion of the main body. The griddle is sized and configured to be removably positioned over and supported by the main body, the griddle including a flat cooking surface and an oppositely facing underside surface. The underside surface extends to define a front end, a rear end, a left end and a right end, the front end extending parallel with the rear end, the left end extending parallel with the right end. Further, the underside surface of the griddle includes diagonal reinforcement portions that extend to exhibit an x-configuration such that the diagonal reinforcement portions extend longitudinally so as to extend transverse along the underside surface relative to each of the front end, the rear end, the left end and the right end of the underside surface of the griddle. The x-configuration defines a central intersection, the central intersection having a central plate coupled directly to the central intersection of the x-configuration.
In another embodiment, the central plate extends substantially parallel with the underside surface of the griddle. In another embodiment, the central plate includes a plate opening defined therein, the plate opening of the central plate configured to be positioned over the central intersection.

In accordance with another embodiment of the present invention, a griddle configured to minimize the effects of thermal stress is provided. The griddle includes a flat cooking surface and an underside surface. The flat cooking surface extends to define a periphery and a splash guard, the splash guard extending upward from the periphery of the flat cooking surface. The underside surface faces opposite of the flat cooking surface, the underside surface extending to define a front end, a rear end, a left end and a right end.

The reinforcement structure 18 may include diagonal support structures 182 that may extend diagonally across the underside surface 98. The diagonal support structures 182 may extend to define an x-configuration or x-structure. Such x-configuration may be formed as a single piece or continuous structure positioned directly against the underside surface 98. The continuous structure of the x-configuration may mean that different structural pieces may be interconnected together and to the underside surface 98 (via welding) to form the x-configuration or general x-structure. The diagonal support structures 182 may extend along the underside surface 98 so as to extend generally between oppositely spaced corners of the underside surface 98 of the griddle 12 such that terminal ends of the diagonal support structures 182 may extend between and adjacent to the front right corner 141 and the rear left corner 143 as well as the front left corner 139 and the rear right corners 145.

In another embodiment, the diagonal reinforcement portions 242 may extend to exhibit an x-configuration. In another embodiment, the diagonal reinforcement portions 242 may extend longitudinally transverse relative to any one of the front end 234, the rear end 236, the first end 238 and the second end 240 to generally exhibit a diamond configuration. Such a diamond configuration may include different pieces interconnected together, via welding, as well as being secured to the underside surface 230 of the griddle, via welding.
The underside surface 230 of the griddle 222 may extend to define first and second front corners 250, 252 and first and second rear corners 254, 256 of the griddle 222, each of the corners being corners of the rectangular configuration. The griddle 222 with the x-configuration of the diagonal reinforcement portions 242 may extend with terminal ends or ends 258 such that the ends 258 may be positioned adjacent corresponding ones of the first and second front corners 250, 252 and the first and second rear corners 254, 256 of the griddle 222. Even though the ends 258 of the x-configuration that are closest to respective ones of the first and second front corners 250, 252 may include other portions of the reinforcement structure 220 that are closer to the first and second front corners 250, 252, such ends 258 may still be considered adjacent to the first and second front corners 250, 252 due to their relative close proximity to the first and second front corners 250, 252 compared to, for example, an intersection point 264 of the diagonal reinforcement portions 242 of the x-configuration.
