A catalytic converter designed to be integrated into a food-cooking appliance and to act, during a cooking cycle in a closed atmosphere and without oxygen being admitted from the outside, to treat the odors in the cooking fumes before the fumes are discharged to the outside, the converter comprising a basic substrate (30) provided with perforations (31) for passing the cooking fumes to be treated, the substrate (30) being coated with an intermediate layer ( 32) having a large surface area, itself provided with a surface component (33) formed of an inorganic solution based on precious metals so as to form the catalytic active layer of the converter, the intermediate layer (32) comprising alumina and cerine so as to form an intermediate layer (32) with a surface area of not less than 150 square meters per gram (m2/g), the amount of alumina/cerine added to the basic substrate (30) lying in the range 30 g/m2 to 35 g/m2, including 15 g/m2 of cerine to 25 g/m2 of cerine. The catalytic converters, in particular, for a deep fryer.

The invention claimed is: 1. A catalytic converter designed to be integrated into a food-cooking appliance, the food-cooking appliance comprising a deep fryer, and to act, during a cooking cycle in a closed atmosphere and without oxygen being admitted from the outside, to treat the odors in the cooking fumes before the fumes are discharged to the outside, said converter comprising a basic substrate (30) provided with perforations (31) for passing the cooking fumes to be treated, said substrate (30) being coated with an intermediate layer ( 32) having a large surface area, said intermediate layer (32) provided with a surface component (33) formed of an inorganic solution based on precious metals so as to form the catalytic active layer of said converter, said intermediate layer (32) comprising alumina and cerine so as to form said intermediate layer (32) with a surface area of not less than 150 square meters per gram (m2/g) , the amount of alumina/cerine added to the basic substrate (30) lying in the range 30 g/m2 to 35 g/m2, including 15 g/m2 of cerine to 20 g/m2 of cerine. 2. The converter according to claim 1, wherein the basic substrate (30) has at least a minimum surface area of 0.0034 m 2/liter of water vapor treated per minute. 3. The converter according to claim 2, wherein the basic substrate (30) is provided with in the range 190 perforations per square inch (PSI) to 400 PSI (in the range 29.49 perforations per square centimeter (PSC) to 62.09 PSC). 4. The converter according to claim 3, wherein the surface component (33) consists of one of a metal, a mixture of metals, a metal oxide, and a mixture of metal oxides, the metal(s) being chosen from platinum, copper, manganese, and palladium. 5. The converter according to claim 4, wherein the surface component (33) is platinum dispersed in the intermediate layer at a concentration of at least 0.02380 mg/m2 and at the most 0. 06666 mg/m2. 6. The converter according to claim 5, wherein the platinum is dispersed at a concentration of about 0.02380 mg/m2. 7. The converter according to claim 1 wherein the basic substrate (30) is a monolithic material having a honeycombed structure consisting of one of alumina and cordierite. 8. An appliance for cooking food in a closed atmosphere, the appliance being equipped with said catalytic converter according to claim 1. 9. The appliance according to claim 8, wherein the appliance further comprises a deep fryer.
