As shown more particularly in
In the embodiment shown, when grill 10 is turned on by pressing power button 46, power indicator 48 is lit. When the user continues to press or actuate increase button 42, plurality 50 of lights illuminate in sequential order from first light 51 until the nth light, where the nth light can be any one of the lights from first light to eighth light 51-58 and where the value of n is determined based upon how hot the user wants heating element 20. If the user sets heating element to its lowest setting, only first light 51 will be illuminated. If the user presses increase button 42 to its next setting or next elevated temperature for cooking, first and second light 51, 52 will be illuminated. This continues until the user wants heating element 20 at its hottest level or most elevated temperature for cooking, in which all eight lights 51-58 will be illuminated.
Regardless of the temperature setting, first light 51 is illuminated before second light 52, and second light 52 is illuminated before third light 53, and this continues until eighth light 58. Further, the number of lights illuminated, or the value of n, is in direct proportion or has a linear relationship to the user actuating increase button 42.
Likewise, the number of lights illuminated decreases in direct proportion, or has a linear relationship, with the actuation of decrease button 44. Hence, for each user determined setting for heating element in a decreasing fashion, plurality of lights 50 will illuminate in sequential order from first light 51 and terminating with nth light, which is any one of the lights 51-58.
Control 40 operates in an easy to read manner such that the user is able to obtain information quickly without having to scan large areas of the grill or read small minutia on a dial or gauge. Because plurality 50 of lights are arranged in an arc, and because the quantity of lights being lit around power button 46 gives the user a visual indication of the level of heat emitted from heating element 20, control 40 gives the user useful information about heating element 20 in a compact area so it is more beneficial than traditional touch controls that are in a straight line across a substantial width of the grill. Moreover, other traditional grills using dials or digital displays with numerals or other minutia are often difficult to read as opposed to plurality 50 of lights.
In the embodiment show, plurality 50 of lights include eight lights, which means n is any value between 1 and 8. In other embodiments, plurality 50 of lights include numerous lights of any quantity, such as 10, 25, or even 1000, which means n is any value between 1 and 10, 1 and 25, or 1 and 1000, respectively.
In the event the user needs to be reminded as to whether or not the number of lights being illuminated indicates a level of heat being emitted from heating element 20, the thickness of power level indicator 62 from narrow end 64 to thick end 66 indicates the heat output, where thick end 66 is proximate to eighth light 58 and narrow end is proximate to first light 51.
As shown in
Because GFI 72 is located on power cord 75 and away from grate 30 and heating element 20, it is easy for the user to reach during an emergency since most emergencies are due to a problem, such as a fire, located at or near grate 30 or heating element 20.

In some embodiments, grill 10 further includes an automatic shut off switch, which comprises at least one temperature sensor and at least one timer. A temperature sensor in communication with heating element 20 can be set at a user determined or manufacturer determined maximum setting, such as 300 degrees Fahrenheit or some other temperature determined to be unsafe, such as a code or standard in the industry, whereupon heating element 20 reaching this temperature would cause the temperature sensor to send a signal to shut grill 10 off. For example, the signal may be an electric signal sent to GFI 72 to power grill 10 off.
Although the signal to power grill 10 off is sent to GFI 72, the power relay that physically cuts the power may be located any where, whether proximate to grill 10 or GFI 72.
The timer may be set at a user determined or manufacturer determined maximum setting, whereupon heating element 20 being on for this maximum amount of time would cause the timer to send a signal to shut grill 10 off. For example, the signal may be an electric signal sent to GFI 72 to power grill 10 off. The following table is an example of times that the timer may be set, after which grill 10 powers itself off.
Although the invention has been described with reference to a particular arrangement of parts, features and the like, these are not intended to exhaust all possible arrangements or features, and indeed many other modifications and variations will be ascertainable to those of skill in the art.
