Abstract

An example of what is new or different with my invention is the use of the shield that I created to guide heat flow (convection), to a measured perimeter around the edges of the grate. Avoiding conduction heat that could bum or sear baked foods is accomplished by using the elevated wire racks. The lid is the oven and the temperature inside the oven is monitored by a thermometer outside the oven.

BACKGROUND OF THE INFORMATION

The common use of an outside propane gas grill is to use radiant heat to grill foods. The amount of heat that is used in the cooking process is determined by heat knobs of the gas grill that change the amount of gas supply. Now, with my invention, this same gas grill can be utilized into a new dimension, a convection heat oven that bakes and roasts like a regular kitchen oven.

BRIEF SUMMARY OF THE INVENTION

This invention uses the lid of the gas grill itself to hold in the regulated convection heat. Also, one side of the lid is the location for the thermometer and heat tube.

A shield made of two pieces of aluminum lays on the grate which permits a calculated amount of open space around the perimeter of the shield. A stainless steel wire rack with legs is elevated two and one-half inches above the shield. The amount of heat entering the lid is controlled by the openings around the shield and the gas control knobs of the gas grill. The accurate thermometer reading assures perfect results.

BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE DRAWING

FIG. 1 Shows an outside gas grill with a hinged lid. [0007]
FIG. 1[0008] a Shows the location of the thermometer face on the outside of the lid; the tube will protrude inside through the lid.
FIG. 1[0009] b Displays the two overlapping aluminum shields laying on the grill grate showing an uncovered space of 1½ inches on each end and a space of ¾ inches on both the back and front end of the rack for proper heat flow.
FIG. 2 Shows one of the two aluminum shields of approximately 4 mils that are folded on each end instead of cutting them for the proper size. [0010]
FIG. 3 Shows the type of thermometer used with the face on the outside of the lid and the tube that protrudes through the lid. [0011]
FIG. 4 Shows one of the two 9″ by 10″ wire racks that are elevated 2½″ over the aluminum shield. [0012]

DETAILED DESCRIPTION OF THE INVENTION

This invention is a kit that contains everything that is required to convert an outside propane gas grill into a convection oven and back to a grill again in seconds. The kit contains two sheets of aluminum (about 4 mils), 10″ by 30″ rolled as a cylinder for shipping (the aluminum is the same weight that roofers use to make roof valleys). These aluminum sheets are used as a shield that lay over the existing grate. The kit contains two stainless steel wire racks 9″×10″ with legs or bends to elevate the racks 2½″ over the shield. The kit also contains an accurate oven thermometer with numbers readable outside the lid for the temperature inside the oven. A tube of sealant is provided to secure the installation of the thermometer. [0013]
Everything will fit in a shipping box 11×11×5″ high, including instructions and recipies. [0014]
This kit can accommodate any outside gas grill with a grate that measures as large as 32 inches or as small as 22 inches. This is a side-to-side measurement (the longest part). This kit will fit just about every manufactured propane gas grill. Most gas grill grates are about 26 to 28 inches and about 15 inches from front to back. To customize your gas grill to a convection oven, the process is easy. The two aluminum shield pieces must be 3 inches shorter than the existing grill grate. The shields are made shorter by folding with any straight edge (a ruler or kitchen counter, etc.). [0015]
They must not be cut because the folds add support. As an example, if a 27 inch long grate measurement is used, the shield must be folded so that it becomes 24 inches long. More support is obtained by folding three inches from each end, instead of only one end. [0016]
The two pieces of the aluminum shield should be placed overlapping over the existing grate so that the existing grate is exposed three-quarters of an inch on the front side and three-quarters of an inch on the back side and, because the shields are already folded, each end side will be exposed one and one-half inches. This important shield is now customized for your propane gas grill. [0017]
The two wire racks are placed on the surface of the shields in the center of the grill. [0018]
If the gas grill has a warming rack inside the lid, it must be removed while the oven is in use. The top hole for the warming rack can be utilized for the thermometer or a new one-quarter inch hole about [0019] 6 inches from the top of the lid can be used. The sealant should be used from inside the lid to secure the thermometer and the heat tube.
When the lid is closed the result is a convection oven. [0020]

Claims

1. What I claim as my invention, is making a convention oven for baking and roasting, from an existing propane gas grill with a lid that opens and closes: This invention does not replace the original use of the propane gas grill; instead, it adds a new dimension. The back-and-forth conversion of grill or oven, when needed, is easy and fast.
