Abstract:
A stove emergency cutoff system comprising:a) a stove having a front wall, a rear wall, a top wall, laterally spaced side wall, a plurality of burners in said top wall, a plurality of switches, and a plurality of control knobs, wherein each switch is connected between a respective one of said plurality of burners and a power source and each control knob is connected to move a respective one of said plurality of switches between a first position connecting said respective one of said burners to a power source and a second position disconnecting said respective one of said burners from said power source; andb) means connected between each of said plurality of switches and the power source for deactivating any said burner that is connected to the power source when food in a cooking utensil on one of said burners is on fire and producing a large flame, so as to shut down said stove, and as a result will cause the fire to go out said deactivating means including:i) an elongated tube extending from within said stove, mounted to and extending up from said rear wall of said stove, and bent over said burners;ii) a pair of stiff wires affixed in an X-shaped configuration to a top end of said elongated tube over said burners of said stove;iii) a piece of nylon cord tightly placed about the ends of said stiff wires to form a box-shaped web;iv) a flexible cable passing through said elongated tube with each end of said flexible cable extending out of an opposite end of said elongated tube;v) a hook affixed to a top end of said flexible cable to engage with said nylon cord;vi) an actuator arm having an aperture, said actuator arm affixed at a first end to a bottom end of said flexible cable within said stove;vii) a normally closed master switch having a lever mounted with said stove for engaging said actuator arm when in the normally closed position, said master switch electrically connected between a main electrical power supply line and a terminal of all of said electrical switches of said burners, whereby said lever is engaged to said actuator arm through said aperture; andviii) a spring mounted internally between said front wall of said stove and a second end of said actuator arm, so that when the lare flame produced by the fire of the food in the cooking utensil reaches said nylon cord and breaks said nylon cord said hook is causing said spring to move said actuator arm forward towards said front wall of said stove, thereby disengageing said lever and said actuator arm and opening said master switch and disconnecting the main electrical power supply line from all of said electric switches of said burners, and wherein said stove is an electric appliance, said burners are electric coils.
