Abstract
Abstract A grooved griddle for grilling or broiling foods. The griddle includes a plate having longitudinal grooves sloped so that food fats that drop into the grooves flow downwardly toward a collection area. The grooves terminate inwardly of the rear of the plate in a configuration which facilitates cleaning. Heat sensors located in recesses in the underside of the plate detect localized temperature drops. The ridges between the grooves are preferably flat to provide uniform sear stripes on the food, and the grooves preferably increase in depth from the rear to the front of the plate to promote grease drainage and uniform heating.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
159 words
A grooved griddle for grilling foods, said griddle comprising: a non-apertured, thick metal grill plate adapted to overlie a heat source, said plate having a sloping uncovered upper surface to allow vaporized fats to be carried upwardly past food disposed thereon, and which includes a plurality of sloping, generally parallel grooves and intermediate ridges defining a continuous, unapertured cooking area whereby liquified food fats from said food thereon are unable to drop through said plate to said heat source, the move elevated extremities of the sloping said grooves terminating short of the upper edge of said plate to define an edge margin to act as a barrier for said food fats, the depth of said grooves being less than half the thickness of said plate and defining a substantial metal mass below said grooves; and a plurality of heat sensors disposed in close proximity to said metal mass below said grooves for sensing temperature drops across said metal Mass.
Claim 2
Dependent Claim
159 words

Claim 3
Dependent Claim
17 words
A grooved griddle according to claim 1 wherein said ridges are flat to provide uniform sear stripes.
Claim 4
Dependent Claim
25 words
A grooved griddle according to claim 1 wherein said grooves increase in depth as they extend from the rear to the front of said plate.
Claim 5
Dependent Claim
30 words
A grooved griddle according to claim 1 wherein said elevated extremities of said grooves are each characterized by a generally arcuate end wall whereby cleaning of said grooves is facilitated.
Claim 6
Dependent Claim
19 words
A grooved griddle according to claim 1 wherein the slope of said plate is approximately one inch per foot.
Claim 7
Dependent Claim
24 words
A grooved griddle according to claim 1 wherein one of said ridges is located at each side of said plate to define side margins.
