Definitions
- the present invention relates to heating devices or intended to be heated during their use and comprising a self-cleaning coating.
- Certain heating appliances such as for example iron soles or even cooking appliances, have qualities of ease of use and efficiency, depending inter alia on the state and nature of the surface of their coating. .
- the iron soles could be improved by the care given to the sliding qualities of the ironing surface, combined with the qualities allowing easier spreading of the laundry.
- One way to obtain these qualities is to use enameled soles with a smooth-looking enamel, possibly with extra thickness lines to spread the fabric during the movement of the iron.
- Other metal soles treated mechanically and / or covered or not with a deposit to facilitate sliding can also be suitable for satisfactory use.
- the soleplate may tarnish by carbonizing in a more or less diffuse manner on its ironing surface, and in a more or less incomplete manner, various organic particles captured by friction on the ironed fabrics.
- Iron soleplates comprising a hard and resistant layer covered, as indicated by US Pat. No. 4,862,609, with a layer improving the surface properties. But this patent does not indicate a solution to combat fouling.
- the walls of cooking appliances are also often covered with an enamelled layer of smooth appearance so that any splashes of grease or food do not adhere to the surface.
- Self-cleaning enamelled surfaces are known, for example in ovens and cooking utensils as described for example in patent US4029603 or patent FR2400876. However, these coatings are not entirely satisfactory with regard to their self-cleaning properties.
- the present invention relates to a heating appliance comprising a metal support at least part of which is covered with a self-cleaning coating, characterized in that the coating comprises:
- an outer layer in contact with ambient air, comprising at least one oxidation catalyst chosen from the oxides of platinoids,
- At least one internal layer located between the metal support and the external layer, comprising at least one oxidation catalyst chosen from the oxides of the transition elements from group Ib.
- the present invention also relates to a method for covering the metal support of a heating appliance with a self-cleaning coating as above, characterized in that it comprises the following steps: - i) the surface of the support is heated metallic to be covered in an oven at around 400 ° C,
- the surface of the metal support to be covered is placed under infrared at a temperature ranging from 400 ° C. to 600 ° C. for a few seconds, iii) a solution of an oxidation catalyst precursor chosen from oxides is sprayed transition elements of group Ib on the surface of the metal support to be covered to obtain the internal layer,
- the surface of the metal support to be covered is placed, with the internal layer, under infrared at a temperature ranging from 400 ° C. to 600 ° C. for a few seconds,
- an apparatus is obtained whose self-cleaning coating has a particularly excellent catalytic activity and whose adhesion to the metal support is very good.
- the organic particles in contact with the outer layer of the coating are oxidized when the device is heated. Furthermore, the synergistic effect obtained by the particular association of an internal layer comprising a specific oxidation catalyst and an external layer comprising a specific oxidation catalyst different from that of the internal layer makes it possible to obtain a coating with particularly effective catalytic activity. Thus, the surface of the coating is regenerated very quickly. For example, when ironing with an iron, the organic particles captured by the soleplate are oxidized. They are somehow burned when the iron is hot, the possible solid residue loses all grip and comes off the soleplate. The sole stays clean. Likewise, in a cooking appliance such as an oven for example, the projections of grease present on the wall of the oven are oxidized hot, the solid residue is detached from the wall which is kept clean.
- the adhesion of the coating to the metal support is particularly good.
- This improved adhesion makes it possible to increase the resistance to friction of the coating, this property being particularly advantageous in the case of an iron soleplate for example.
- heating appliance is meant within the meaning of the present application, any appliance, article or utensil, which during its operation reaches a temperature at least equal to 45 ° C, and preferably at least equal to 90 ° C.
- the device can reach this temperature operating by means which are specific to it, such as for example a heating base integrated into the apparatus and provided with heating elements, or by external means.
- Such devices are for example iron soles, cooking appliances, ovens, grills, cooking utensils.
- the outer layer of the coating according to the invention comprises an oxidation catalyst chosen from the oxides of platinoids.
- platinum is meant, within the meaning of the present application, the elements having properties similar to those of platinum, and in particular, in addition to platinum, ruthenium, rhodium, palladium, osmium and iridium .
- the outer layer comprises an oxidation catalyst chosen from palladium oxides, platinum oxides and their mixtures.
- oxidation catalysts are well known in themselves, as well as their processes for obtaining them, without it being necessary to describe in detail their methods of preparation respectively.
- platinum as an oxidation catalyst, its catalytically active form can be obtained by calcination or decomposition of a chloro-platinic acid salt or any other precursor.
- any oxidation catalyst retained according to the present invention must remain sufficiently stable at the operating temperature of the device, and this within the limits of the useful life of the device.
- the surface of the outer layer is in direct contact with the ambient air and with organic dirt.
- organic soiling is meant in the sense of the present application any combustible or oxidizable substance in contact with the ambient air, completely or partially.
- any residue of synthetic fibers, as used in textile articles for example of organic polymer such as polyamide or polyester, any organic residue of washing product and optionally of softening product, any organic substance such as splashes of fat or food.
- the oxidation catalyst chosen from platinum oxides is distributed on and / or in the outer layer of the coating, where it is in contact with dirt, and depending on all or part of the outer layer, continuously or discontinuously.
- the oxidation catalyst chosen from among the platinoids is distributed on the external surface of the sole, intended to be brought into contact with the laundry.
- the coating can comprise, in addition to the oxidation catalyst chosen from platinoid oxides, any internal support layer which is catalytically inert with regard to oxidation.
- This support which adheres to the metallic and catalytically inert support is preferably chosen from aluminum or silicon compounds, such as, for example, alumina in divided or particle form, enamel, polytetrafluoroethylene and their mixtures.
- the catalytically inert support with regard to oxidation is an enamel with low porosity and / or roughness, on a micrometric and / or nanometric scale.
- the enamel is for example a vitreous enamel.
- the enamel should preferably be hard, have a good glide and resist the penetration of steam or hot humidity.
- the outer layer of the coating preferably has a thickness, measured according to the RBS method described in Example 1 of the present application, ranging from 10 nanometers to 500 nanometers, and more preferably ranging from 20 nanometers to 120 nanometers.
- the oxidation catalyst of the outer layer being active at a coating temperature greater than or equal to 90 ° C., it cleans said coating when the latter is heated at least to such a temperature.
- the internal layer comprises at least one oxidation catalyst chosen from the oxides of the transition elements of group Ib, preferably chosen from copper oxides, silver oxides and their mixtures.
- oxidation catalysts are well known in themselves, as well as their processes for obtaining them, without it being necessary to describe in detail their methods of preparation respectively.
- silver oxide as an oxidation catalyst, commercial nitrate of silver sold by the company Aldrich can be used as a precursor.
- the catalytically active inner layer has a thickness, measured according to the RBS method described in Example 1 of the present application, ranging from 20 nanometers to 50 nanometers.
- the oxidation catalyst present in the inner layer has a good affinity with the oxidation catalyst present in the outer layer.
- the support is annealed and, during this step, the oxidation catalyst present in the inner layer can diffuse in the outer layer and the oxidation catalyst present in the outer layer can diffuse in the inner layer.
- the outer layer comprises as an oxidation catalyst a palladium oxide and the inner layer comprises as the oxidation catalyst a silver oxide.
- the silver oxide has diffused in the external layer and the external layer therefore comprises a mixture of palladium oxide and silver oxide. A particular synergistic effect has been observed at the level of the catalytic activity of the coating in such an embodiment of the invention.
- the heating device is in the form of an iron soleplate comprising an ironing surface and the covering covers the ironing surface.
- the heating appliance is a cooking appliance comprising walls capable of coming into contact with organic dirt and the coating covers these walls.
- the catalyst acts at the operating temperature of the device and the coating is kept clean as the device is used.
- a second operating mode during a so-called self-cleaning phase, before or after the use of the appliance, the latter is adjusted to a high temperature, equal to or higher than the highest operating temperatures, it is then left on standby for a predetermined time, during which the oxidation catalyst produces its effect. The user can thus maintain his device regularly, without waiting for a harmful fouling.
- the metal support of the device according to the invention can be based on any metal commonly used in the field of heating devices such as aluminum, steel or even titanium.
- This metallic support may itself be covered with a protective layer such as for example an enameled layer before being covered with the coating of the present invention.
- the device comprises an intermediate enamel layer situated between the metal support and the catalytically active internal layer of the coating.
- the application of the internal and external catalytically active layers to the metallic support, covered or not by an enameled layer, is preferably done by pyrolysis, by heating the surface to be covered and then spraying on this hot surface with a solution containing a precursor of the oxidation catalyst.
- precursor any chemical or physicochemical form of the oxidation catalyst, which is capable of resulting in, or of liberating the latter by any suitable treatment, for example pyrolysis.
- the surface of the metal support to be covered is heated in an oven to approximately 400 ° C. and then placed very briefly, for example for a few seconds, under infrared, until reaching a surface temperature ranging from 400 ° C to 600 ° C.
- This operation softens the surface of the support and makes it possible to increase the subsequent adhesion of the coating.
- a solution of the precursor of the oxidation catalyst chosen from the transition elements of group Ib is sprayed onto the surface of the metal support. On contact with the surface, the precursor oxidizes and fixes on the support and the water evaporates. A layer of thickness ranging from 20 to 50 nm is deposited. The support cools very quickly.
- a support is obtained covered with a coating whose self-cleaning properties are particularly good.
- Figure 1 is a sectional view of an iron soleplate according to the invention
- Figure 2 is a sectional view of an iron soleplate according to the invention comprising an enameled protective layer.

- the soleplate comprises also a heating base 6 provided with heating elements 7.
- the support 2 and the base 6 are assembled by mechanical means or by gluing.
- the inner layer 3 comprises a catalyst oxidation chosen from the oxides of the transition elements of group Ib and the outer layer 4 comprises an oxidation catalyst chosen from the oxides of platinoids.

- the protective layer 5 is made of enamel.
- a clean soleplate of enameled aluminum iron is placed on an aluminum support of about 2 cm to conserve heat as well as possible. The whole is heated to 400 ° C in an oven. The sole, with the support, is placed for a few seconds under infrared until a surface temperature of between 400 ° C. and 600 ° C. is reached. Silver nitrate, sold by the company Aldrich, is dissolved in water at 4 g / 1 and is sprayed by means of a pneumatic gun on the sole. A layer of about 40 to 50 nm, measured according to the RBS method, is deposited.
- the RBS (Rutherford Backscattering Spectroscopy) method is an analysis technique based on the elastic interaction between a 4 He 2+ ion beam and the component particles of the sample.
- the high energy beam (2MeV) hits the sample, the backscattered ions are detected at a teta angle.
- the spectrum thus acquired represents the intensity of the ions detected as a function of their energy and makes it possible to determine the thickness of the layer. This method is described in WK Chu and G. Langouche, MRS Bulletin, January 1993, p 32.
- the soleplate is again heated in the oven at 400 ° C and then placed for a few seconds under infrared at a temperature between 400 ° C and 600 ° C.
