Definitions

  • the invention relates to a pyrolysis cleaning cooking oven having a catalyst in the smoke evacuation circuit.
  • Pyrolysis is a known operation for cleaning baking ovens which consists of destroying by heat the fatty deposits or dirt which appear on the walls of an oven during cooking or reheating of food.
  • the temperature of the oven must be 500 ° C for the pyrolysis to take place normally, which is obtained by putting simultaneously into service at least the vault resistors and the sole resistors that the oven can contain.
  • the catalyst is brought to a temperature of 350 ° C. and becomes effective before the temperature of the center of the furnace reaches the saturation temperature in smoke.
  • Such an oven is known from FR-A 2 365 927.
  • the subject of the invention is therefore a pyrolytic oven with a smoke catalyst which does not have these drawbacks, and which allows the pyrolysis operation to be carried out without additional consumption compared to the ovens of the prior art.
  • the cooking ovens generally comprise at least one resistance of the vault, in the upper part, and one of the hearth, in the lower part of the oven.
  • the floor resistor can be in two parts which can be supplied separately.
  • the smoke evacuation duct is located in the upper part, near the vault.
  • the invention starts from these observations and also aims at the production of a catalyst pyrolysis oven, the priming of which takes place before the furnace is saturated by the fumes.
  • a pyrolytic electric oven with smoke catalyst comprising at least one vault resistance and one sole resistance of usual values, is characterized in that it comprises means for putting into service at the start of an operation. simultaneously and exclusively pyrolysis the vault resistance and part of the sole resistance, such that the power supplied by this part of sole resistance is less than the power supplied by the vault resistance, and in that the catalyst consists in a material which allows its priming exclusively thanks to the convection heat passing through the duct where it is located and coming from the oven thanks to said vault resistance and sole resistance part, before the oven is saturated by the fumes.
  • the catalyst consists of a cellular ceramic impregnated with platinum oxide in an amount such that it initiates when it is at a temperature below 300 ° C.
  • This temperature can easily be obtained in the conduit where the catalyst is located using conventional vault and sole resistors.
  • resistors of higher value which would lead to higher consumption during cooking and pyrolysis.
  • the ignition temperature of the catalyst is obtained by using exclusively resistors used for cooking, it will happen under certain cooking conditions that the catalyst becomes effective, if its temperature is higher than the ignition temperature. In this case, if fumes appear during cooking, they will be purified of harmful gases.
  • the catalyst when the catalyst has reached its initiation temperature, the then The heat distributed to the cooking chamber is modified so that the pyrolysis temperature is reached in the oven.
  • means are provided for detecting the fact that the catalyst has reached its initiation temperature.
  • a pyrolysis cleaning oven 1 having a catalyst 2 based on cellular ceramic impregnated with platinum oxide, which initiates at 250 ° C., and which is placed in a conduit 3 for discharging the fumes.
  • the oven comprises at least one vault resistor 4 and a hearth resistor comprising two parts 5, 6 which can be supplied separately.
  • the first part 5 is, for example, a peripheral part and the second part 6 is for example the central part. It is indeed common to make ovens having such a hearth resistance structure.
  • Means for commissioning the resistors are provided. They are for example constituted by a switch 7 with several positions.
  • the vault resistance and the peripheral part 5 of the floor resistance are supplied. This is achieved by putting the switch in position 1 in solid lines in the figure.
  • the peripheral part 5 of the floor resistor is generally less soiled by dirt than the central part 6. This therefore explains the choice of supplying this peripheral part.
  • the peripheral part 5 of the floor resistor has a lower power than that of the vault resistor
  • the simultaneous entry into service of the vault resistor 4 and of the peripheral part 5 of the hearth resistor allows the oven to heat up without significant creation of smoke.
  • the vault resistance with a power greater than the peripheral part of the sole resistance, more easily influences the catalyst.
  • the simultaneous commissioning of the peripheral part 5 of the floor resistor promotes the convection of heat to the duct 3, and prevents too much of the energy supplied by the vault resistor from being used for reheat the enclosure, and therefore be lost to reheat the duct 3 where the catalyst 2 is located.
  • a vault resistance with a power of approximately 700 W and a peripheral portion of sole resistance of approximately 450 W one quickly obtains, depending on the types of oven, a temperature in the center of the oven between 250 ° C and 350 ° C which allows the initiation of the catalyst before saturation of the furnace by the fumes.
  • the power is modified to quickly obtain the 500 ° C. in the furnace, for example by putting in service in addition the central part 6 of the hearth resistance and any other resistances that may include the oven (position 2 of switch 7).
  • thermostat 8 which allows an all-or-nothing regulation of the temperature in the center of the oven in order to maintain it at 500 ° C.
  • the thermostat 8 opens and closes a switch 9 which controls the general supply oven resistances.
  • the temperature of the catalyst is a function of the temperature of the center of the furnace.
  • the switch 7 can be associated with a reversing thermostat (not shown) which detects the temperature in the center of the oven and switches on the higher power as soon as the temperature of the center of the oven is such that the temperature of the duct is sufficient for the catalyst to prime.
  • a reversing thermostat not shown
  • priming takes place for a temperature in the center of the oven between 250 ° C and 350 ° C.
  • the exact threshold is determined during start-up settings.
  • a variant consists in placing the thermostat in the duct 3, in the immediate vicinity of the catalyst. However, there is a risk of the thermostat getting dirty.
  • the switch 7 is associated with a clock, reset at the start of a pyrolysis operation.
  • the rise in temperature of an oven is a function of time, and for a given type of oven, knowing which resistances are in service, we can determine by measurement when after commissioning, the oven reaches a temperature given.
  • FIG. 2 represents an improved variant of the oven of the invention.
  • the switch 7 is associated with an electronic device 10 which makes it possible to activate the desired resistances during the cooking operations and the pyrolysis operations.
  • the device 10 controls the opening or closing of the contacts 11, 12, 13 placed in the supply circuit of the vault resistors 4 and of the sole 5, 6.
  • the device makes it possible to obtain associations in parallel. It is conceivable that the device allows series-parallel associations.
  • the device is associated with thermostat 8 from which it derives its control information.
  • the device closes the switches 11 and 12 respectively associated with the vault resistors 4 and the peripheral sole 5.
  • thermostat trigger threshold at the oven temperature corresponding to the priming of the catalyst.
  • the device switches on the power necessary to bring the oven to 500 ° C and regulate this temperature.
  • the device is associated with a clock which switches when the ignition time is exceeded.
