Definitions

  • the invention relates to a stove with pyrolytic self-cleaning
  • the muffle can be operated by a heating element arranged in at least one wall area and possibly with additional forced-air heating, the muffle being ventilated by a forced-air fan and equipped with means for pyrolytic self-cleaning.
  • the object of the invention is to provide an objectively justified initiation of pyrolytic cleaning processes.
  • the arrangement according to the invention for solving this problem is characterized in that an automatic pyrolysis system recognizing the pollution limit value controls the pyrolytic self-cleaning, the pollution limit value recognizing one
  • the automatic pyrolysis system consists of a limit value comparator and a pyrolysis control, which are connected to each other, and that the limit value comparator enters operational oven pollution values in a register via sensors arranged in the cooking chamber, compares them with an oven contamination limit value and, if the limit value is exceeded, pyrolysis Activation activated, the sensor system consisting of at least one sensor that changes its electrical conductivity due to contamination rates.
  • a further advantageous embodiment of the invention is characterized in that the pyrolysis control (12) activated by the limit value comparator (11) triggers the pyrolytic self-cleaning.
  • the cleaning process of the oven muffle is recommended by the appliance itself if it is sufficiently dirty.
  • the contamination of the oven muffle can be detected and processed by suitable sensors, which, for example, assess the electrical conductivity, or other systems, which, for example, use ultrasound to make distinctions.
  • Another way to record contamination values of the oven muffle is to use a time-dependent and usage-dependent system for the respective stove.
  • a stove 1 is a stove 1 equipped with pyrolytic self-cleaning with a cooking chamber 2, a pyrolysis display 3, operating elements 4, an electrical input and stove control 5, an air blowing device 6, a door handle 7, a viewing window 8 and one in the cooking chamber 2 hole pattern for circulating air heater 9, recognizable.
  • the cooker 1 with pyrolytic self-cleaning, equipped with the pyrolysis display 3, may have sensors in the cooking space 2, but these are not shown.
  • a limit value comparator 11 receives operational oven contamination values via this sensor system arranged in the cooking space 2. The limit value comparator 11 compares these values with an oven contamination limit value and, if the limit value is exceeded, a pyrolysis control 12 is activated, which in turn enables a heating control for pyrolytic self-cleaning 13, so that pyrolytic self-cleaning can be initiated. If the limit value comparator 11 has decrypted a limit value violation, then the pyrolysis display 3 determines an optical and / or acoustic signal. Operating elements for the pyrolysis display 3 allow the display to be deleted, possibly connected with a reset in the limit value comparator register, or an immediate initiation of the pyrolysis.
  • the limit value comparator 11 forms an actual value for oven contamination from the type of use and frequency of use of the oven functions, enters this into the contamination register of the limit value comparator, compares it with a limit value for oven contamination and if this limit value is exceeded, the pyrolysis control 12 is activated.
  • the pyrolysis control 12 activated by the limit value comparator 11 triggers or signals the pyrolytic self-cleaning.
  • the pyrolytic self-cleaning can be signaled optically or acoustically by the pyrolysis display 3.
  • the pyrolysis control 12 releases the heating control 13 after an acknowledgment signal, so that the pyrolysis process can begin in the cooking space.
  • the pyrolysis control 12 can also be used to force pyrolytic self-cleaning after repeated acknowledgment.
  • the contamination values transmitted by the sensor technology or by adding up time values to the limit value comparator 11 are added up in a limit value comparator register. If the comparison with the limit value comparator register and a stored pollution limit value indicates that the limit value has been exceeded and the operator wishes to delay pyrolytic self-cleaning, the pollution values added up in the limit value comparator register can be deleted or reduced using a deletion signal. A forced start for pyrolytic cleaning is also possible.

Claims (9)

  1. Four à autonettoyage par pyrolyse, dont le moufle peut fonctionner avec un élément de chauffage placé au moins dans une paroi et avec, éventuellement, un chauffage supplémentaire à circulation d'air, le moufle pouvant être ventilé par l'intermédiaire d'un ventilateur d'air ambiant et étant équipé de moyens destinés à l'autonettoyage par pyrolyse, caractérisé en ce qu'un système automatique de pyrolyse, qui identifie une valeur limite d'encrassement, commande l'autonettoyage pyrolytique, ce système automatique de pyrolyse étant constitué d'un comparateur (11) de valeurs limites et d'une commande (12) de pyrolyse, tous deux reliés entre eux, et le comparateur (11) de valeurs limites introduisant dans un registre, par l'intermédiaire d'une unité sensorielle disposée dans l'espace de cuisson (2), des valeurs d'encrassement du four, valeurs qui sont conditionnées par l'utilisation, les comparant ensuite avec une valeur limite d'encrassement du four et activant la commande (12) de pyrolyse lorsque la valeur limite est dépassée, l'unité sensorielle étant constituée d'au moins un capteur qui modifie sa conductivité électrique en fonction du degré d'encrassement.
  2. Four selon la revendication 1, caractérisé en ce que le capteur modifie sa conductivité électrique en fonction du degré d'encrassement conditionné par le fonctionnement du four.
  3. Four selon la revendication 1, caractérisé en ce que la commande (12) de pyrolyse, activée par le comparateur (11) de valeurs limites, déclenche l'autonettoyage pyrolytique.
  4. Four selon la revendication 3, caractérisé en ce que la commande (12) de pyrolyse signale l'autonettoyage pyrolytique de manière visuelle à l'aide d'un affichage (3) de pyrolyse.
  5. Four selon la revendication 3, caractérisé en ce que la commande (12) de pyrolyse signale l'autonettoyage pyrolytique de manière sonore à l'aide d'une indication de pyrolyse.
  6. Four selon la revendication 3, caractérisé en ce que, après un signal d'accusé de réception, la commande (12) de pyrolyse débloque une commande (13) de chauffage destinée à l'autonettoyage pyrolytique.
  7. Four selon la revendication 3, caractérisé en ce la commande (12) de pyrolyse impose l'autonettoyage pyrolytique et débloque la commande (13) de chauffage destinée à l'autonettoyage pyrolytique.
  8. Four selon la revendication 3, caractérisé en ce que l'utilisateur peut effacer le registre du comparateur de valeurs limites qui additionne les valeurs d'encrassement.
  9. Four selon la revendication 8, caractérisé en ce que l'autonettoyage pyrolytique peut être déclenché par un démarrage forcé.
