A motion detector is integrated into the safety device and serves as the front-end to a temperature sensor switch. The switch is designed to trigger a power shut-off mechanism when high utensil temperature is encountered. The mechanism will be deactivated if motion is detected within a set periphery of the stove appliance. It will automatically be reactivated a set time later after no motion is detected. This invention will not interfere with normal cooking procedures while drastically reducing the possibility of kitchen fires due to cooking.

[ We claim:] [1.] An automated fire safety device for a gas or electric stove-top burner utilizes a motion detector governed temperature sensor switch to reduce fire risks in unattended cooking, said motion detector having a built-in timer deactivates the said temperature sensor switch when a user is present or if the period since user motion has last been detected is within a preset time to allow a user a full control of burner operation and resumes sensor switch functions when there is no user present and the said preset time has expired, said temperature sensor switch having a temperature sensor, a power shut-off switch, a linking or controlling mechanism between the sensor and the shut-off switch and an optional load-sensing switch, operable to measure a temperature of a utensil placed on the said burner and to positively shut off power to said burner when the following condition, referred to as condition B is met: there is no user present, the preset time on the said motion detector timer has expired and the temperature measured by the said temperature sensor has reached a preset level indicating an overheating condition.
