Definitions

  • the invention relates to irons.
  • Hand irons are preferably light in weight and should glide lightly over the fabric to facilitate handling when ironing, with the ironing surface coming into contact with the fabric having the desired smoothing effect.
  • Irons of this type have a heating device by means of which an iron soleplate which forms the contact surface with the material to be ironed and is usually made of metal or plastic is heated.
  • the temperature of the soleplate can usually be adjusted depending on the particular ironing material, and since the smoothing effect is often increased by the action of steam, many irons have a water container and means for generating steam, the steam during the ironing process from in the soleplate provided openings emerges.
  • the ironing surfaces of such devices are often made of aluminum and / or provided with a low-friction coating made of a polymer such as polytetrafluoroethylene.
  • a polymer such as polytetrafluoroethylene.
  • scratches or other damage for example when trying to clean the surface of the soleplate of fixed suspended therefrom foreign bodies, or as a result of Bu g elvorgangs even if have settled for Example dirt particles in the material to be ironed, and such scratches or damage are suitable for impairing the smoothing effect of the iron on the items to be ironed.
  • an iron is provided with a composite sole made of a carrier part made of heat-conducting material, which is connected to the heating device of the iron, and a ceramic layer adhering to the carrier part, which has a thickness of about 50 / um - 500 microns and has a smooth ironing surface, the surface quality of which should be at least about 2 ⁇ m roughness.
  • This ceramic surface has high wear and impact resistance and has excellent static and sliding friction properties.
  • the ceramic layer also does not adversely affect the heating time of the device, which essentially corresponds to that of an iron provided with an uncoated iron soleplate, for example consisting only of aluminum.
  • the ceramic layer consists of bonded ceramic particles, for example of a carbide, boride or a metal oxide such as aluminum oxide, cobalt oxide, titanium oxide or mixtures of such ceramic materials, the Vickers hardness number (diamond pyramid) of which is over 1,000 with a test load of 10 g.
  • a method for producing an iron comprises the following steps: production of a heat-conducting support part which can be connected to the heating device of the iron and has a rough surface, application of an approximately 50 ⁇ m to 500 ⁇ m thick layer ceramic material on the rough surface of the carrier part, and smoothing the surface of the applied layer of ceramic material in order to obtain a flat ironing surface.
  • various methods such as vapor deposition or surface T Steam Spraying can be used, according to preferred embodiments, after roughening the surface of the carrier part by sandblasting to achieve a typical roughness depth of at least 10 microns entrained in a plasma stream and heated ceramic particles are sprayed onto the roughened surface of the carrier part, the heated particles being impacted deform onto the carrier part in such a way that they form a bonded ceramic layer with a density of at least about 80%.
  • the surface of the ceramic layer thus obtained is then polished by polishing to such an extent that a surface quality of at least about 1 pm of roughness results.
  • the iron has a a water container and means containing steam generation body that are provided in the soleplate with the vapor space in Related openings through which the vapor g by the soleplate on the bracket is provided, guided ut is that a radiator is embedded in the carrier part and that a power supply and a controller for adjusting the temperature of the soleplate are provided.
  • the iron is easy to handle, has an easy-to-clean soleplate with high wear and shock resistance, and the friction properties of the friction pair fabric / ceramic material are comparable to or even superior to those of conventional irons with polymer-coated soleplates.
  • Fig. 1 shows an iron
  • the body 10 has an iron soleplate 12 and a handle 14.
  • a water container is formed in the body 10 and is filled and emptied through an opening 16.
  • a heating element contained in the body 10 is in close connection with the soleplate 12, is supplied with current via a power supply cable 18 and regulated via a temperature controller 20 in order to adjust the temperature of the soleplate 12.
  • the iron also has a steam regulator 22.
  • In the bottom of the soleplate 12 there is an arrangement of openings 24 (as shown in FIG. 2) through which steam exits to increase the ironing effect.
  • the soleplate 12 consists of a ceramic layer 28 that adheres firmly to the underlying and heat-dissipating aluminum support 30 (as shown in the microphotograph of the cross section of FIG. 3).
  • the composite sole 12 is obtained by cleaning and roughening the aluminum support 30 by means of sandblasting (the roughened surface that forms has a typical roughness depth of about 20 ⁇ m), after which an up to about 200 ⁇ m thick ceramic layer is applied.
  • sandblasting the roughened surface that forms has a typical roughness depth of about 20 ⁇ m
  • aluminum oxide in spherical shape with a diameter of 10 ⁇ m is heated in a plasma stream generated by a plasma spray gun and sprayed onto the carrier part 30, the heated balls becoming slices of approximately 1 when they strike the carrier Deform micron thickness and thus form a bonded ceramic layer 28 of a density of approximately 90%.
  • the surface 32 thereof is first smoothed with a nylon disk in which silicon carbide is embedded and then polished with diamond paste to a nominal surface roughness of approximately 1 micron.
  • Fig. 4 shows a photomicrograph of the polished ceramic surface (aluminum oxide), the dark spots representing voids or pores.
  • the hardness of the Vickers aluminum oxide particles (diamond pyramid) is around 2,400 with a test load of 10 g.
  • the heating-up time of the polished soleplate 32 essentially corresponds to the uncoated soleplate consisting only of aluminum, the sole is also easy to clean and also has a high wear and impact resistance.
  • the friction properties of irons with ceramic-coated iron soles according to the invention were investigated and compared with those of irons whose iron soles consist only of aluminum and of aluminum with a polymer coating such as Teflon (polytetrafluoroethylene).
  • the friction properties of the irons involved in the comparison were measured using different textile materials and under different ironing temperatures.
  • the results of the comparison of the friction properties of the irons on lines are shown in FIGS. 5 and 6, the static friction being compared in FIG. 5 and the sliding friction in FIG. 6.
  • the friction of aluminum soles according to the prior art is represented by a circle, the friction of the ceramic-coated composite sole according to the invention by a square and the friction of Teflon-coated (polytetrafluoroethylene) aluminum soles by an "X". While in these three types of soleplate the static friction on linen was essentially the same at ambient temperature (with a force of 200 g or slightly above), the static friction with the ceramic-coated composite sole on linen was lower at 125 ° C and 175 ° than with the two irons Aluminum sole or Teflon-coated sole. As Fig.
  • the irons according to the invention have equally good or even better frictional properties than commercial irons, the ironing soles of which are polymer-coated (e.g. Teflon).
