RELATED APPLICATIONS 
     The present invention was first described in and claims the benefit of U.S. Provisional Application No. 61/121,804 filed Dec. 11, 2008, the entire disclosures of which are incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to electric home appliances, and in particular, to a system for sensing dangerous conditions and the subsequent automatic shutoff of electric home appliances. 
     BACKGROUND OF THE INVENTION 
     Electric home appliances represent an ever-growing percentage of household amenities. In particular, electric version of items such as stoves, microwaves, toasters, and the like dominate the marketplace. The automatic nature of such items makes for easy preparation, maintenance, and accurate heating of food, beverages, and the like. Such electric appliances allow a user to automatically heat the device to specific temperatures, allow a user to time preparation in an automated fashion, and allow a user to perform many other similar tasks in a hands-free, automatic manner. 
     The shift to automatic food heating and preparation appliances, among other household appliances, has led to an increase in house fire and the like as a result of increased absence of a user during the time of use. Such accidents can easily result if a burner, heater, or other similar component or appliance is left on and unattended for a period of time. Fires may result from gas buildup, overheating, a misplaced item which catches fire, or any number of other mishaps which would potentially be mitigated by the presence and attention of the user. 
     Various attempts have been made to provide automatic safety features for stoves and the like. Examples of these attempts can be seen by reference to several U.S. patents. U.S. Pat. No. 5,094,259, issued in the name of Hsu, describes an automatic shut-off safety device for gas stoves. The Hsu device detects the extinguishment of a flame on a gas stove and shuts off the flow of gas to prevent a dangerous gas buildup. 
     U.S. Pat. No. 6,032,663, issued in the name of Pencheon, describes a stove emergency cutoff system. The Pencheon device has a sensor located above a stove&#39;s burners which senses the presence of a large flame and shuts off the corresponding burner. 
     U.S. Pat. No. 6,046,441, issued in the name of Daffron, describes a combustion activated device for disabling an electrical appliance. The Daffron apparatus can sense the presence of a flame on an electrical appliance and subsequently shuts off power to the appliance. 
     While these devices fulfill their respective, particular objectives, each of these references suffer from one (1) or more of the aforementioned disadvantages. Many such devices are not adaptable to types of stoves such as gas, electric, and the like. Also, many such devices do not sense an adequate range of dangerous conditions and instead only focus on one particular situation. In addition, many such devices are not easily retrofitted to existing appliances. Furthermore, many such devices are not adaptable to a variety of appliances. Finally, many such devices involve physically intrusive components which may be either in the way of a user of the appliance or perceived as aesthetically unpleasing. Accordingly, there exists a need for an emergency shutoff system for cooking appliances without the disadvantages as described above. The development of the present invention substantially departs from the conventional solutions and in doing so fulfills this need. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the prior art, it has been observed that there is need for an emergency shut-off system for deactivating an electric stove upon sensing smoke or heat and thereby reducing kitchen fires. Such an electric stove preferably has a first plug connected to a first outlet for receiving power therefrom. The first outlet is electrically mated to a circuit breaker box including a ground fault circuit interrupter. 
     Notably, the emergency shut-off system preferably includes a smoke detector having an input and an output respectively, and an emergency shut-off device adapted to be interconnected to the electric stove. Such an emergency shut-off device may be interconnected to the input and the output of the smoke detector. In this manner, upon detecting smoke or heat, the smoke detector sends a current to the emergency shut-off device which concurrently trips the ground fault circuit interrupter thereby terminating power to the first outlet and the electric stove. 
     Such an embodiment may further include a corresponding method of utilizing an emergency shut-off system for deactivating an electric stove upon sensing smoke or heat and thereby reducing kitchen fires. Such an electric stove is preferably connected to a first outlet for receiving power therefrom. The first outlet may be electrically mated to a circuit breaker box including a ground fault circuit interrupter. Notably, such a method preferably includes the steps of: providing a smoke detector having an input and an output respectively; providing and interconnecting an emergency shut-off device to the electric stove as well as the input and the output of the smoke detector; and upon detecting smoke or heat, terminating power to the first outlet and the electric stove by the smoke detector sending a current to the emergency shut-off device and thereby tripping the ground fault circuit interrupter. 
     In one embodiment, the emergency shut-off device may include a top housing and a bottom housing removably connected thereto, a circuit board located within the top and bottom housings, first and second resistors connected to the circuit board, and a contactor connected to a surface of the circuit board. Such a contactor may be a relay receiving a five volt direct current from the output of the smoke detector. 
     In one embodiment, the emergency shut-off system may further include a transmitter connected to the smoke detector. Such a transmitter includes an internal transmitter power supply for providing power to the transmitter. A receiver may be interconnected to the electric stove panel. Such a receiver may include a receiver power supply for providing power to the receiver. Notably, the transmitter transmits a wireless signal when smoke or heat is detected. In this manner, the receiver receives the signal which terminates power to the electric stove. 
     In one embodiment, the present invention may include an emergency shut-off system for deactivating an electric stove upon sensing smoke or heat and thereby reducing kitchen fires. Such an electric stove preferably has a first plug connected to a first outlet for receiving power therefrom. The first outlet may be electrically mated to a circuit breaker box without a ground fault circuit interrupter. Notably, such an emergency shut-off system preferably includes a smoke detector including an input and an output as well as a reset button and a battery interconnected thereto. An emergency shut-off device is adapted to be interconnected to the electric stove wherein such an emergency shut-off device is interconnected to the input and the output of the smoke detector. Also, the reset button may be interconnected to the emergency shut-off device. 
     Notably, the emergency shut-off device may further include a second plug adapted to be interconnected to a second outlet, a junction box adapted to be interconnected to the second outlet, a third plug adapted to be plugged into the second outlet, and a forty amp (40 A) contactor having a 120-Volt alternating current activation coil wired to the third plug. Such a contactor preferably has a first pair of poles adapted to be interconnected to a 230-Volt alternating current coming from the circuit breaker. The contactor may further have a second pair of poles adapted to be interconnected to the first outlet. In this manner, upon detecting smoke or heat, the smoke detector sends a current to the emergency shut-off device which terminates power to the first outlet and the electric stove. 
     Such an embodiment may further include a method of utilizing an emergency shut-off system for deactivating an electric stove upon sensing smoke or heat and thereby reducing kitchen fires. The electric stove having a first plug connected to a first outlet for receiving power therefrom.
