  • DE 30 39 246 A1 discloses an extractor hood with a controllable blower motor for use in kitchens, which has a sensor element that responds to moisture and / or haze and / or smoke and / or heat and faces the stove surface. Furthermore, two sensor elements can be present, one on the side of the cooker hood facing the stove and the other on the side of the cooker shielded from the stove surface. From DE 37 37 712 C2 an electric cooker is known which automatically switches off one or more heat sources after switching on a heat source via an operating switch and after a predetermined time without any further switching, and likewise after the predetermined time since the last switching of a heat source the electric stove is switched off automatically. Likewise, DE 35 35 743 A1 a shutdown safety device for electric cookers is known, which ensures a complete shutdown of the electric cooker in the event of overheating.
  • the power supply includes a resettable switch-off device to switch off the power supply when the current rises above a predetermined value.
  • the shutdown device comprises a smoke detector which is mounted outside the cooker and is capable of emitting an electrical signal in the event of smoke.
  • a device for interrupting the power supply is connected to the above-mentioned signal transmitter in order to automatically interrupt the power supply to the cooker.
  • a device for detecting a predetermined boiling state of a liquid is known from the US-PS 50 79 407, which is located on a hob of a kitchen range.
  • a moisture sensor delivers a first signal at a predetermined humidity, which actuates a timer circuit which supplies a second signal which is capable of triggering an audible or visible alarm, and also to control or control the heating source with which the liquid is heated. switch off.
  • a stable multivibrator is used within the timer circuit, on which the signal from the moisture sensor is applied.
  • the invention has for its object to reduce the given operational risk of cookers and hobs, which are operated energetically with electrical energy or flammable gases, and the associated risk of a house fire and thus the environmental impact of pollutants, which are economically justifiable in such fires to reduce; Furthermore, any existing stove or hotplate should be able to be retrofitted.
  • the object is achieved, according to the invention, by various sensors arranged above the kitchen stove and / or the hotplate, which are smoke sensors and / or temperature sensors and / or moisture sensors and / or grease vapor sensors and / or flame sensors, the signals of which are processed by evaluation electronics equipped with a timer whose an exit with a Separating element, preferably an electrical switch or electromagnetic valve, is connected for the energy supply for the kitchen stove or the hotplate, in such a way that the evaluation electronics limit values for smoke and / or temperature and / or water vapor and / or grease vapor and / or flames can be specified, which are at If the time supply exceeds a predefined time, switch off the energy supply to the kitchen range or the cooking zone with a time delay, the evaluation electronics having a reset input that can be operated by the operator, with which the output signal of the evaluation electronics for switching off the energy supply to the kitchen range or the cooking range can be reset within the preset switch-off time.

  • the safety device can have an extinguishing system which can be activated when detecting flames and / or a specific, predetermined concentration of smoke development and / or when a predetermined temperature is exceeded.
  • the evaluation electronics can emit acoustic and / or optical warning signals before the kitchen stove is switched off.
  • the evaluation electronics of the safety device can trigger an increasing or swelling acoustic and / or optical signal for signaling to the operator so that he actuates the reset, in order thereby to activate the pre-armed switch-off signal within the possible range Deactivate switch-off time.
  • the safety device can preferably be integrated in an extractor hood above the kitchen range or the hotplate.
  • the safety device can have a central temperature sensor connected to the evaluation electronics for integrally detecting the temperature, which is able to act on its response to the main safety switch.
  • a method for monitoring kitchen stoves and / or hotplates which are operated energetically with electrical energy or combustible gases, using an electrical safety device arranged above the kitchen stove and / or the hotplate with evaluation electronics which have at least one acoustic and / or optical signal detector is characterized in that temperature, smoke development, water and / or grease vapor and / or flames are monitored by means of electrical sensors which are preset to a predetermined limit value and whose output signals are recorded in an electronic evaluation unit, with a or respond to several of the limit values within a predetermined limit value period of the acoustic signal and / or optical signaling device, but within this time period no cut-off of the power supply to the kitchen range or the cooking zone is triggered and the operator in response to the response of the acoustic and / or optical signal Signal detectors, preferably within a further, predefinable reset time period, must manually trigger a reset signal in order to ensure a further energy supply to the kitchen range and / or the cooking zone and the
  • an electrical safety device for a kitchen stove 1 is preferably and for the most part integrated into an extractor hood 2, a separating element 3 being arranged within an energy supply line 4 for the kitchen stove 1, which can be a gas pipe or an electrical pipe is either an electromagnetically actuated valve or an electrical isolating switch.
  • An energy line 6 leads from the separating element 3 to the kitchen stove 1, and a control line 5 leads into the separating element 3, with which the separating element 3 with the extractor hood 2 and the units arranged there electrically connected is.
