Definitions

  • the present invention relates to the general technical field of flat heating structures of the sandwich type, intended to assume at least two differentiated thermal functions.
  • the present invention relates to a sandwich heating structure, externally limited by two elements having a certain veryness and of which at least one is a heating plate capable of diffusing the heat produced by a resistive element extending between the two elements.
  • a structure is therefore able to provide heat production which can be differentiated from each element in the case of the use of two heating plates to ensure distinct thermal functions such as heating, vaporization or simply the thermal dissipation.
  • the present invention applies in particular, but not exclusively, to household appliances, and among these, preferably to appliances capable of operating in a humid environment or of being in contact with humidity, such as irons in general whether steamed or dry (use of pattemouille), or even such as fryers or broilers of all kinds.
  • the heating structure is advantageously integrated in an iron of the steam or dry type, and the present invention also directly relates to an iron provided with such a heating structure.
  • an iron soleplate comprising a metal sheet intended to diffuse heat produced by a resistive element and coming into contact with the textile article to be ironed.
  • the resistive element is electrically insulated using a polymerized plastic material, of the silicone resin or epoxy or polyimide type, consisting of a lower insulating coating layer and an upper insulating coating layer. The whole of the resistive element and of these two layers of electrical insulation is bonded to the metal sheet by means of an adhesive layer.
  • the sole must then perform a double thermal function, since it involves on the one hand evaporating water from the upper surface of the sole, and on the other hand assuming ironing proper through the lower surface of said sole.
  • sandwich structure soles externally limited by two heat diffusing elements such as metal plates between which are arranged a plurality of intermediate layers superimposed on each other at starting from a central element consisting of the resistive element.
  • sandwich structure can be illustrated, for example, by the sole described in French patent application FR-A2,641,291, in which the intermediate layers between the central resistive element and the two external metal sheets are made up of collaminated alloy layers brazing, the resistive element being separated from the latter by electrically insulating layers made of micanite sheets.
  • the use of a sandwich structure of this type can be considered as generally satisfactory in terms of the thermal resistance properties of the sole.
  • the object of the present invention therefore aims to remedy the various drawbacks listed above, and to provide a high temperature heating structure with a sandwich structure capable of assuming at least one and preferably two differentiated thermal functions, capable of improving the dissipation of heat from the resistive element without negatively influencing the resistance over time of the proper internal structure of the heating structure whatever the thermal stresses undergone, and this at a reduced manufacturing cost.
  • An additional object of the invention aims to provide a heating structure produced in a particularly simplified manner, and having improved air and vapor tightness characteristics.
  • Another object of the invention aims to provide a heating structure having an improvement in the resistance over time of the cohesion of the various layers constituting it, and this despite strong thermal constraints.

  • the lower metal plate 2 forms the ironing sole proper intended to come into contact with a textile article to be ironed not shown in the figure, while the upper metal plate 3 at least partially forms the lower wall of a vaporization chamber 16 consequently arranged directly above the heating structure 1.
  • the function of sealing against steam and external aggressions in general is ensured as described above by mounting a track resistive 14, de-energized forming peripheral seal at the end of the first resin layer 5.
  • the sealing function can be improved by the interposition of a seal 17 of silicone type, disposed between a lateral peripheral wing 18 of the vaporization chamber 16 and the upper metal plate 3.

  • the different layers of the heating structure of the sole are then held in place at the orifice 21 by riveting the threads, so that the upper flange 23 of the orifice 21 forming the rivet not only assumes a function of compression of the different layers of the heating structure between the plates, 2, 3, so as to promote heat exchange and to avoid deformation, but also a vapor tightness function.
  • the tightness is further improved at the passage openings 21, as shown in FIGS. 5 and 6, by the incorporation, in the first resin layer 5, of tracks of resistive elements 24, in the form of a ring surrounding the external diameter of the walls 22 constituting the spinning of the orifices 29.
  • the heating structure according to the invention thus has, thanks to the presence of three layers of thermoplastic resin, on the one hand good properties of heat transmission between the different layers, and on the other hand also good resistance to mechanical shocks and while maintaining good adhesion properties between the different layers.
  • heating structure does not require the use of a heavy and expensive industrial infrastructure, and the cost of such a heating structure can therefore be substantially reduced.
  • dielectric properties of the heating structure can be obtained at the lowest cost, by limiting the quantities of the thermoplastic materials used to form the first layer of resin 5.
  • the heating structure according to the invention and in particular the iron comprising such a heating structure has remarkable vapor tightness properties obtained at a lower cost. Sealing is in fact ensured by eliminating the mounting of a traditional sealing element through the use, as a sealing means, of certain tracks of the resistive element 4.
  • the incorporation of a heating structure in accordance with the invention in the ironing soleplate of a steam iron allows, thanks to the good heat dissipation properties of the heating assembly, to mount the vaporization chamber directly above the upper plate of the sandwich structure. This results in a great simplification of the internal arrangement of the iron influencing in a posi cost and ease of manufacture.
  • the heating structure according to the invention is preferably incorporated in an iron of the steam type, but it is obvious that its mounting can extend to any type of iron in general, and also to receptacles fryers of the culinary type, to devices ensuring a grilling function, or having to ensure the formation of steam, such as coffee makers or kettles for example.
