The present disclosure relates to a griddle and gas burner range and, more particularly, to a heat barrier that reduces hot air or heat under the griddle plate from escaping to the burners.
In general, for proper performance, open top gas burners require a balanced mix of primary air, fuel, and secondary air. If this balance is disrupted, the quality of the flame of open top gas burners is adversely affected.
However, during operation of a griddle plate, hot air or heat is expelled into adjacent areas above aeration pans of the open top gas burners. This hot air or heat affects the flame of the open top gas burners because the air/gas mixture is incorrect.
An apparatus consistent with the present disclosure is directed to improving the overall performance of an open top gas burner which is disposed adjacent to a griddle and during operation of the griddle.
An apparatus consistent with the present disclosure prevents the heated air or heat from the operating griddle from being expelled into the area above the adjacent aeration pans of the open top gas burners.
An apparatus consistent with the present disclosure provides a heat barrier installed between the griddle and burner area so as to eliminate the escape of hot air or heat.
According to one aspect, the present disclosure provides a griddle and gas burner range, including: a griddle comprising an electric heating element, and a griddle plate that is disposed over the electric heating element; at least one open top gas burner disposed adjacent to the griddle; and a heat barrier installed between the griddle and the at least one open top gas burner, so as to block the escape of heat from the griddle and into an area of the at least one open top gas burner during operation of the griddle.
According to another aspect, the present disclosure provides a griddle and gas burner range, wherein the heat barrier comprises an elongated plate disposed in a fire box of the griddle, and wherein the elongated plate extends upward to a height above an edge of the fire box.

The accompanying drawing figures incorporated in and forming a part of this specification illustrate several aspects of the invention, and together with the description serve to explain the principles of the invention.
The exemplary embodiments set forth below represent the necessary information to enable those skilled in the art to practice the invention. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the invention and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.
Moreover, it should be understood that terms such as top, bottom, front, rear, upper, lower, upward, downward, right, left, right side, left side, and the like used herein are for orientation purposes with respect to the drawings when describing the exemplary embodiments and should not limit the present invention.
The present inventors tested a cooktop of a 60 inch range having a 24 inch griddle and open top gas burners which are disposed adjacent to a griddle, and discovered that the leveling, expansion, and twisting motion of the griddle plate during operation of the griddle was expelling hot air or heat into the adjacent areas above the aeration pans of the open top gas burners. As a result, the heat from under the griddle plate would escape and adversely affect the open top gas burner performance.
More specifically, when the hot air or heat from the griddle plate is expelled into the adjacent areas above the aeration pans of the open top gas burners, the flames of the open top gas burners appear to be “lazy.” A lazy flame occurs when the air/gas mixture tends to have too much gas so that the flame has poor combustion and elongates because the flame is reaching for additional air to properly balance the air/gas mixture.
The hot air or heat from the griddle plate that is expelled into the adjacent areas above the aeration pans of the open top burners also adversely affects the performance of the griddle plate per se as heat is lost and thus adversely affects the temperature performance of the griddle plate.
An apparatus consistent with the present disclosure prevents the heated air or heat from the operating griddle from being expelled into the area above the adjacent aeration pans of the open top gas burners.
The griddle and gas burner range 100 is shown as a 60 inch range with six (6) burners and a 24 inch griddle, although this configuration is only exemplary and other configurations are within the scope of this invention. For example, four (4) burners, with two burners on each side of the griddle, or two (2) burners on just one side of the griddle, or just one (1) burner on one side or both sides of the griddle are also contemplated. Each open top gas burner B includes an aeration pan B″ which provides support for a corresponding cooking grate B′ on which various cooking pots or pans are placed during cooking. Each of the open top gas burners B may include a gas mixer tube for conducting gas and air to within the open top gas burners B, and each mixer tube has a mixer head with an adjustable air shutter for individually adjusting the gas-air mixture to the individual burners, as is conventional and thus not shown. Also, open top gas burners B that do not use an adjustable air mixer may be used, as is conventional.
The griddle and gas burner range 100 includes a griddle 102 disposed between a plurality of open top gas burners B. As noted above, six burners B are shown in
As will be described in more detail below, a heat barrier 105 is installed between the griddle and burner area so as to eliminate the escape of hot air or heat. In the exemplary embodiment shown in
As shown in
A plurality of manual controls C is disposed, for example, on a front face of the griddle and gas burner range 100. For example, individual controls can be provided for each open top gas burner B and for the each griddle portion 102A and 102B. Further, controls for the oven portion O of the range 100 are also provided. The oven portion O is shown, for example, as two side-by-side ovens, with an upper portion of the two doors D to the oven portion O being shown in
The particulars of the heat barrier 105 according to an exemplary embodiment consistent with present disclosure will now be described with reference to

The heat barrier 105 (105A, 105B) can be made from any material that can withstand the heat from the electric heating element 104 (104A, 104B) of ˜550° F. while having some reflective properties. Suitable materials include, but are not limited to, various kinds of steels, or aluminum, or porcelain. Steel or aluminum is preferred.
The present invention has substantial opportunity for variation without departing from the spirit or scope of the present invention. For example, the number of open top gas burners B, the number oven portions O, the size of the range, the size of the griddle can all be varied.
Those skilled in the art will recognize improvements and modifications to the exemplary embodiments of the present invention. All such improvements and modifications are considered within the scope of the concepts disclosed herein and the claims that follow.
