Abstract

The subject of the invention is a device for the protection of stand-alone thermic household appliances, especially cooking stoves and hotplates against unwanted consequences of untimely interference and against unwanted interference of children. A household appliance (1) has a sensor (2) provided on its upper external edge detecting presence of a person under an angle of between approx. 30° and approx. 80° upwards, and has a clock or rather a timer with a predetermined switch-off time, preferably 15 minutes, which is triggered by the sensor (2). When the sensor (2) detects presence of a person (5), it triggers the clock and unlocks operating controls (3); when the person (5) removes himself, the sensor (2) locks the operating controls (3) thus starting a time interval.
