Definitions

  • the invention relates to the field of pyrolysis ovens.
  • the operation of pyrolysis makes it possible to clean a dirty oven whose walls are covered with soiling.
  • An oven has a cooking cavity and a duct evacuation connecting the cooking cavity to the outside environment which is example the kitchen in which the oven is located.
  • the cavity temperature becomes very high, for example of the order of 500 ° C, and under the effect of heat, the dirt detaches from the walls of the cavity. Soiling in gaseous form is discharged into the environment outside after passing through the exhaust duct.
  • soiling also includes all gaseous products combustion products likely to generate bad odors, even if these products do not settle on the walls of the oven cavity and by therefore do not properly "dirty" the oven.
  • a dirt cracking located in the exhaust pipe and at the end of the duct on the side of the cavity.
  • Cracked cells usually have an activation temperature above which dirt passing through the cracking cells are cracked, ie broken down into residues.
  • the activation temperature is reached in pyrolysis mode, when the temperature in the upper part of the cavity rises. Indeed the cell of cracking being close to the cavity, the heat of the cavity heats the cell in a big way. This cracking results in the removal of bad odors in pyrolysis mode.
  • the activity A of the cell as a function of the temperature T of the cell is represented in FIG. 1.
  • the activity A of the cell represents the more or less complete cracking rate dirt passing through the cell.
  • a rate of zero means that the cell is completely inactive, that is to say that practically no dirt is broken down during the crossing of the cell.
  • a rate equal to one means that the cell is completely active, that is to say that practically all the soils are completely decomposed, the cracking is then complete, during the crossing of the cell.
  • Complete cracking transforms dirt into elementary residues, mainly water and carbon dioxide. This switching between the inactive and active states of the cell occurs for a temperature T 0 called cell activation temperature.
  • the actual cracking cells differ from the ideal case.
  • the activity A of the cell as a function of the temperature T of the cell is shown in FIG. 2.
  • the cell is completely inactive below a certain minimum temperature T 1 and completely active above a certain maximum temperature T 2 , at least with regard to cracking reactions liable to generate bad odors.
  • T 1 and T 2 the cracking cell is partially active and the cracking is incomplete for certain cracking reactions, that is to say that the dirt is only partially decomposed.
  • These partially decomposed soils are the source of bad odors, in particular during oxidation reactions of alcohols, aldehydes, and organic compounds in general.
  • the temperature T of the cell is greater than T 2 , while it is between T 1 and T 2 in cooking mode.
  • the solution of the invention consists in making the cell inactive by cooking mode, while keeping it active in pyrolysis mode.
  • the states inactive and active are understood at least with respect to cracking reactions likely to generate bad odors.
  • the good smell characteristic of dishes being cooked is thus preserved; but that smell can be a useful element for the user of the oven for the appreciation of the degree completion of the cooking of a dish.
  • a pyrolysis oven comprising a cooking cavity, an evacuation duct connecting the cavity to the middle outside, a dirt cracking cell located in the duct and active in pyrolysis mode, characterized in that the oven includes means making the cell inactive in cooking mode.
  • These means are for example a sliding cracking cell in the exhaust duct.
  • the cell In pyrolysis mode, the cell is placed in a position close to the cavity.
  • the cell In cooking mode, the cell is placed in a position further from the cavity.
  • the means making the cell inactive are means of cooling the cell.
  • These means are for example a particular arrangement of the circuit cooling so that the air carried by the cooling licks the exhaust duct at the level of the cracked. By thermal conduction from the periphery to the center of the cracking cell, it is then cooled.
  • the cooling means comprise an air flow of cooling through the cell when the oven is in cooking mode.
  • An additional cooling air circuit is for example provided to send forced air by a fan into the exhaust duct of way to cross the cell.
  • the oven comprises advantageously a main cooling circuit including a bypass conveys the cooling air flow.
  • FIG. 3 schematically represents a first preferred type of oven according to the invention.
  • the air flows are represented by arrows.
  • the oven comprises an oven cavity 1 generally defined by an enclosure 10, the enclosure 10 comprising a muffle and an insulator surrounding the muffle.
  • the enclosure 10 has an inner wall 11 and an outer wall 12.
  • a discharge pipe 2 connects, directly or indirectly, the cavity 1 to the outside environment 3.
  • a cell 4 for cracking soiling.
  • the cell 4 is advantageously located partially above and partially below the outer wall 12 of the enclosure 10.
  • the oven also preferably includes a main cooling circuit 6 conveying a flow f 3 of air.
  • the flow f 3 of air conveyed by the main cooling circuit 6 licks the duct 2.
  • the main circuit 6 advantageously comprises a bypass 7 which conveys the flow f 1 of cooling air from the cell 4.
  • the flow f 1 of cooling air and the flow f 3 of air are preferably pulsed by a fan 5.
  • the flow f 1 of cooling air leaves the main cooling circuit 6 at the level of the discharge duct 2 to follow the bypass 7 until reaching the upper part of the cavity 1.
  • the pressure prevailing in the main circuit 6 at the bypass 7 is preferably greater than the pressure prevailing in the cavity 1.
  • the flow f 0 d air from the cavity 1 engages in the duct 2 causing the flow f 1 of cooling air in its movement.
  • the flows f 1 and f 0 pass through the cell 4 and continue in the duct 2 in the form of a flow f 2 of air.
  • the flow f 2 of air is mixed with air coming from the external medium 3, before passing through the fan 5 and continuing in the main cooling circuit 6 in the form of the flow f 3 of air.
  • the branch 7 preferably comprises a branch zone 70 located along the duct 2 and extending from the outer wall 12 of the enclosure 10 to the inner wall 11 of the enclosure 10.
  • This area 70 surrounds for example the end of the duct 2 on the side of the cavity 1 and then constitutes a cylindrical ring connecting the main cooling circuit 6 to the cavity 1.
  • the ratio between the average section of the duct and the minimum section of the bypass is preferably between ten and twenty.
  • the diameter of cell 4 is for example 35 millimeters, while the thickness of the crown surrounding cell 4 is of the order of a millimeter.
  • the only bypass 7 allows for example to lower the temperature T of the cell 4 from 190 ° C to 150 ° C in cooking mode.
  • the intensity of the flow f 1 of cooling air is advantageously on the one hand sufficiently large so that in cooking mode the temperature T of cell 4 is lower than the minimum temperature T 1 and on the other hand sufficiently low so that in pyrolysis mode the temperature T of cell 4 is higher at the maximum temperature T 2 .
  • the flow f 1 of cooling air makes cell 4 inactive in cooking mode while keeping it active in pyrolysis mode.
  • Cavity 1 usually includes a grill heating element 8 in its upper part.
  • the heating element 8 operates generally continuously, while during most cooking it does not works only intermittently.
  • the relative proximity of the heating element 8 and cell 4 allows the temperature variation of cavity 1 between the cooking mode and the pyrolysis mode to have an influence on cell 4 large enough to switch it between inactive and active states, and thus avoid a partially active state of cell 4 leading to a incomplete cracking of dirt and generating bad odors in the external environment 3.
  • the types of cooking during which the element heater 8 runs continuously do not have reactions of cracking likely to generate bad odors at temperature that cell 1 then has in cooking mode.
  • the cracking cell 4 is preferably a cell catalytic, i.e. it contains a catalyst responsible for a cracking of dirt by catalysis within cell 4.
  • Cell 4 is for example consisting of a ceramic cylinder pierced with small channels whose axis is parallel to the axis of the cylinder and whose interior is lined by the catalyst. The channels have for example a diameter of the order of or several millimeters.
  • the catalyst can be palladium or platinum.
  • cell 4 The air upstream of cell 4, that is to say on the side of cavity 1, is laden with dirt.
  • cell 4 must satisfy the air flow constraints imposed by the exhaust duct 2 and the ventilation system represented here by the fan 5.
  • the flow imposed in cell 4 must be compatible with the kinetics of the reaction for example catalysis taking place in cell 4.
  • all the air which passes through the discharge duct 2 also passes through the cell 4, this in order to there is little or no dirt in the air entering the environment exterior 3.
  • FIG. 4 schematically represents a preferred embodiment of part of FIG. 3, namely the vicinity of the cell 4 and the branch 7.
  • the branch 7 comprises a zone 70 which extends substantially from the outer wall 12 of the enclosure 10 to the inner wall 11 of the enclosure 10.
  • the zone 70 advantageously surrounds the end of the duct 2 and then constitutes, all around this end, a cylindrical ring connecting the main cooling circuit 6 to the cavity 1.
  • This cylindrical crown has for example a thickness of one to a few millimeters.
  • the zone 70 is preferably connected to the parts of the furnace by means of orifices. Between the main circuit 6 and the zone 70, on all or part of the periphery of the conduit 2 are located one or more upper orifices 73.
  • the lower openings 74 and upper 73 are distributed regularly around the periphery of the duct 2 in the form of holes.
  • the minimum section of the bypass 7 is advantageously located at the orifices 74 so as to better control the flow of cooling air arriving at the end of the duct 2 on the cavity side 1.
  • Zone M must be of sufficient size to allow good homogenization of the air flows before crossing cell 4.
  • FIG. 5 schematically represents a second preferred type of oven according to the invention.
  • This second type of oven is similar to the first type described in Figure 3. The differences include the following.
  • the oven has a grill screen 9 usually located just above the grill heating element 8, in the upper part of the cavity 1.
  • the grill screen 9 has a hole shown in dotted lines to let the flow f 0 of air going from the cavity 1 to the duct 2.
  • the branch 7, instead of extending along the duct 2, comprises two parts 71 and 72, which are on the one hand a channel 71 going from the main circuit 6 cooling at the upper part of the cavity 1 and on the other hand a space 72 situated between the screen 9 of the broiler and the inner wall 11 of the enclosure 10 at the level of the upper part of the cavity 1.
  • the flow of air numbered f 2 can for example arrive directly in the main cooling circuit 6.
  • the cell 4 is located for example just below the outer wall 12 of the enclosure 10.
