Definitions

  • the invention refers to a clothes iron sole that is especially applicable to steam irons of the type wherein the sole has an exterior enamel layer.
  • the object of the invention is to achieve a greater hardness of the sole, less friction when sliding and greater simplicity in the manufacturing process.
  • the invention also refers to a process for manufacturing said sole.
  • soles basically comprised of a first injected aluminum body, in which some tube-shaped heating resistors are inserted, and a second body, which constitutes the sole of the clothes iron and that is formed by a laminated aluminum sheet, are known in the steam iron sector.
  • This second body is provided with an enamel coating to improve the sliding of the clothes iron.
  • the laminated aluminum sheet that constitutes the sole is connected directly to the molded aluminum body, and this laminated aluminum sheet is coated with an enamel coating, made from an enamel frit vitrified at a temperature between 500oC and 600oC.
  • the enamel is harder or less hard and it has also been proven that it has more or less sliding resistance. The less hard the enamel coating is, the sole coated with this enamel has a greater sliding resistance and is less resistant to becoming scratched.
  • the invention provides for a clothes iron sole for steam irons that is constituted as of a laminated iron sheet or plate that is joined to the base of the iron, said base being made up of the injected aluminum, and prior to this connection the enameling of the iron sheet is carried out.
  • the vitrification or curing may be carried out at higher temperatures than those provided for in European patent EP-B-0200647 and in European patent application EP-A-0378479, since this vitrification may be done at temperatures between 700oC and 900oC.
  • vitrification of this enamel can be carried out at between 700oC and 900oC implies that the enamel surface has a hardness greater than 30% with regard to the enamel applied to laminated aluminum.
  • the enamel surface provided for in the arrangement of the invention has a greater hardness and, consequently, more resistance to scratching and, as we have mentioned above, this greater hardness determines better sliding of the sole of the clothes iron, which is one of the purposes of the enamel coating.
  • the greater hardness achieved in the enamel to obtain greater sliding and greater scratching resistance represents greater brittleness of the enamel, in such a way that the enamel may peel more easily in the case of accidental knocks, and this danger of peeling of the enamel is even higher on the periphery of the sole.
  • the base of molded aluminum has a recess or hollow in which the iron plate is located, in such a way that the periphery of this enameled sole remains totally protected.
  • the recess or hollow may be provided for in the most part of the surface of the base, with the exception of a small peripheral section, or on the contrary, it may exclusively consist in a channel provided for close to the edge, which runs along the perimeter of the clothes iron, in such a way that in order to protect the enamel of the laminated iron plate, this plate is thinner than the previous one and has a flange that is introduced in said channel, in such a way that the enamel periphery remains perfectly protected at the same time that this channel represents a means of mechanical connection to the base.
  • the enamel coating may consist of depositing one or several layers of this enamel product.
  • Figure 1 shows a partial sectioned view of one portion of a sole of a clothes iron in accordance with an embodiment of the invention.
  • Figure 2 shows a partial schematic sectioned view of another embodiment of the invention.
  • the sole of the invention is constituted starting from a base (1) made of molded aluminum in which the corresponding heating resistor (2) is inlaid, and besides it includes the steam outlet holes (3).
  • a hollow or recess has been made in the base, in which a laminated iron plate (4) is housed, which may remain assembled to the base (1) by mechanical connection or by chemical connection (for example, with silicone), as well as by a combination of both.
  • an enamel layer (5) prior to the cited connection between the base (1) and the laminated iron plate (4), on the laminated iron plate (4) (at least, on the surface that corresponds to the exterior surface of the plate, in other words, to the sliding surface) is deposited an enamel layer (5), whose vitrification or curing is done at a temperature between 700oC and 900oC. This vitrification or curing of the enamel at the indicated temperature makes the enamel surface harder than in the known arrangements and this, also, determines greater scratching resistance and a lower sliding friction coefficient.
  • the enameling is defined by several layers of enamel.
  • a first coating of the enamel layer whose coating may cover all of the surfaces of the plate (4), that is vitrified at a temperature between 700oC and 900oC (preferably between 800oC and 850oC) is done.
  • a second layer of enamel that is applied to the exterior or lower surface of the plate (4) and that reproduces the corresponding pattern of the sole (for example, in the form of alternate rhombi in the form of a chessboard and whose sides have a slant of 37o with regard to the longitudinal axis of the sole), and that is vitrified at a temperature between 700o and 900oC (preferably between 700oC and 800oC), is carried out.
  • the hollow or recess remains located in such a way that the enamel does not reach the periphery of the body (1), whereby the entire periphery of the enamel remains protected, preventing it from undergoing peeling by knocks.
  • the laminated iron plate (4') is assembled on the base (1), as indicated above, with the particularity that close to the edge of the base, a channel (6) has been made in which a flange (7) provided for on the periphery or end of the iron plate (4', is inserted, in such a way that the periphery of the enamel remains protected, and besides, in this way, a mechanical connection with the base (1) is carried out.
  • the vitrification of this coating may be done at a temperature between 700oC and 900oC, with which the enameled surface is harder than in the known systems; in this way, the plate (4) of the sole slides more easily and has a greater scratching resistance; the inconvenience of the brittleness of the coating is eliminated by means of the system of protection of the periphery of the enameled surface.
