Definitions

  • the invention relates to an iron comprising a soleplate intended to slide on a fabric, heating means for heating the soleplate, a thermal detector for measuring a temperature of the fabric during ironing operations and for monitoring the iron. , fixing means for securing the detector to the sole by thermally insulating it.
  • Document JP 4-5998 describes an iron comprising in particular a thermal detector for measuring the temperature of a fabric during ironing.
  • the detector is inserted into the soleplate of the iron. So that the detector is not too strongly influenced by the temperature of the soleplate, a thermal shield is placed around the detector. The constitution of the thermal shielding is not revealed in the document.
  • the temperature measurement of the fabric must be carried out.
  • the iron cannot remain stationary at the risk of burning the fabric. Therefore, for the control of the parameters of the iron, the response times of the detectors must be very short.
  • the detector must therefore have a low thermal inertia without being vulnerable to thermal inputs from the sole. he It is therefore not permissible for the temperature of the detector to be influenced too much, in dynamic regime and in static regime, by the temperature of the soleplate.
  • the object of the invention is therefore to meet these requirements with the aid of specific fixing means, of low cost, making it possible to subject the thermal detector to the soleplate of the iron.
  • the fastening means comprise a flexible dimpled blade of low effusiveness, the blade being intended to keep the detector thermally isolated from the sole and to press the detector flexibly against the fabric during ironing, the dimpled blade being subject to the sole. by a rigid thermal insulating support.
  • the fixing means are thus rigid enough to avoid significant bending of the detector, which prevents any embrittlement, while correctly applying the detector to the fabric to ensure good thermal contact.
  • Low effusiveness is characterized by low thermal conductivity, low specific mass, low heat capacity.
  • the thermal detector takes an equilibrium temperature closer to the temperature of the sole (generally significantly higher than 100 ° C) than the temperature of the fabric (generally close to room temperature).
  • the temperature of the detector must drop very quickly to the temperature of the fabric.
  • the time constant of the detector is around 0.1 to 0.4 seconds.
  • the honeycomb blade is embedded in the support to thermally isolate it laterally from the sole and improve its mechanical strength.
  • the fixing means give good lateral insulation of the detector parallel to the plane of the sole.
  • the detector is coated with a thin protective layer. This layer can cover the support, at least partially, to seal between the detector and the support.
  • Figure 1 a diagram of an iron fitted with a thermal detector.
  • Figure 2 a diagram of a first embodiment of the fixing means of the thermal detector according to the invention.
  • Figure 3 a diagram of a second embodiment of the fastening means of the thermal detector according to the invention.
  • Figure 4 a diagram of a particular embodiment corresponding to the second mode.
  • Figure 5 a sectional view of a detector placed in fixing means which give the detector a slightly domed shape towards the outside.
  • FIG. 1 represents an iron 10 of known type comprising a soleplate 11, heating means 12, a thermal detector 13 and fixing means 14 which join the detector 13 to the soleplate 11 by thermally insulating them from one the other.
  • the thermal detector is used to regulate the heating means and / or the emission of steam in the case of a steam iron.
  • the honeycomb blade 110 is formed of a first flexible and thermal insulating material, such as a felt, having by its constitution a honeycomb structure therefore very ventilated providing both the required flexibility and the required thermal insulation.
  • a first flexible and thermal insulating material such as a felt
  • Felt has the advantage of being a very good thermal insulator.
  • the temperature of the felt can rise above 100 ° C when the felt is not in contact with the fabric. Thanks to its low heat capacity involved and its low effusiveness, it allows the detector to return very quickly to a temperature close to that of the fabric.
  • Other cellular materials can also be used, for example a very low density silicone foam (0.1 to 0.2 approximately) or materials with a honeycomb structure such as the polyaramide material called "Nomex" *. They can be used alone or preferably in combination with a felt which provides additional flexibility.
  • the felt prevents the detector from being damaged by direct contact with the honeycomb.
  • the felt may itself be provided with an interlayer, for example a polyimide sheet, to prevent the honeycomb material from piercing the felt.
  • Commercial felts can be used which resist temperatures up to around 250 ° C and have a very low density of the order of about 0.1 to 0.2. * trademark
  • a felt-based support does not have sufficient mechanical properties to be mounted and held in isolation on an iron soleplate without the detector being damaged either during assembly or during use.
  • a support 120 which provides the required mechanical rigidity and satisfactory additional thermal insulation.
  • This support is for example made of "Teflon” *, a material which is suitable for the range of temperatures usually encountered with an iron. * trademark
  • One face of the honeycomb blade 110 receives the detector 13 which is maintained for example by pressure or by bonding.
  • the detector 13 is covered with a protective layer 150 of small thickness, for example made of polyimide, to ensure the sealing and the mechanical protection of the detector.
  • a protective layer 150 of small thickness for example made of polyimide, to ensure the sealing and the mechanical protection of the detector.
  • the other face of the blade 110 is also held by pressure on the support 120.
  • a thin intermediate sheet 140 can be placed at the interface between the detector and the felt to prevent the detector from rubbing against the felt.
  • the detector being generally deposited on a substrate, the latter can constitute either the protective layer 150 or the interlayer sheet 140 depending on the mounting direction given to the detector.
  • the support 120 is provided with a tip 130 intended to pass through the sole 11. The tip is provided with a passage for guiding and isolating electrical connections 15 connected to the detector 13.
  • One side B of the sole is in contact with the fabric.
  • Another face A of the sole is in contact at least in part with a reserve of water (not shown), the water transforming into vapor on contact with the sole.
  • the steam thus produced passes, during ironing, through the soleplate through orifices 17.
  • the support 120 provided with its tip 130 must ensure the water vapor tightness on the side of the side A. This is obtained, for example, by forcing it slightly into the sole and / or by gluing the support.
  • the mechanical strength of the support therefore serves both to ensure a rigid and waterproof attachment with the sole and to maintain the blade.
  • the honeycomb blade being quite fragile, it is therefore avoided to open it on the side of side B. Therefore, to obtain a correct lateral thermal insulation, preferably the blade is embedded in the support.
  • the protective layer 150 is then extended to cover the junction between the blade and the support in order to prevent the passage of moisture or water vapor.
  • the combination of the blade and the rigid support therefore provides an optimal solution to the problems encountered in fixing a thermal detector to the soleplate of an iron.
  • This combination combines a honeycomb blade of very low effusiveness and of low heat capacity but which does not necessarily have good mechanical qualities, with a support having very good mechanical qualities but which is not necessarily as good a thermal insulator as the felt, and which, if used alone, would not be sufficient to meet the requirements.
  • the heat capacity of the fixing means As much as possible. This reduction can lead to reducing the dimensions of the fixing means. It may then happen that the desirable thickness to be given to the support becomes so small that its mechanical qualities are reduced.
  • This problem is solved by making the support in two parts: a first part having as preponderant quality its thermal insulation and a second part having as preponderant quality its mechanical rigidity. The material forming the second part is then selected for its good rigidity even at small thicknesses.
  • the support 120 is then formed of two parts: an external part 124, in contact with the sole, chosen first for its qualities of insulation, but nevertheless rigid, for example Teflon, and an internal part 122, in contact with the blade 110, formed by a material chosen in the first place for its qualities of rigidity, for example Celeron *.
  • This last material in particular, retains a very good rigidity even for a very small thickness and this even after long periods of maintenance at high temperature. Its thermal insulation qualities are nevertheless less good than those of Teflon. It is also more suitable for receiving the protective layer 150 by bonding.
  • the complementarity of these two materials makes it possible to obtain a support having sufficient thermal insulation and sufficient mechanical rigidity even for a very small thickness, therefore for a low capacity. calorific. * trademark
  • FIG. 4 An exemplary embodiment in the case where the support is formed of two parts is shown in FIG. 4.
  • the external part 124 and the internal part 122 have recesses 125 which lighten each of the parts on their peripheries.
  • the heat exchanges between the external part 124 and the internal part 122 on the one hand and the heat exchanges between the external part 124 and the sole 11 on the other hand, are thus reduced.
  • Other ways of reducing the bearing surfaces can be envisaged by a person skilled in the art.
  • the surfaces of the supports 124 and 122 can be made reflective, in particular those facing the sole. This can be achieved by depositing a reflective layer in the infrared (aluminum, gold) for example by evaporation.
  • the protective layer 150 is slightly flush with the outside of the sole 11. This arrangement is provided so that during ironing the detector 13 can be applied, for example. through the protective layer 150, on the fabric to be ironed. It is possible to promote this contact with the fabric by giving the blade 110 a slightly domed shape, for example in its center. In a particular embodiment, this case is shown in the diagram in Figure 5 which shows a section of the fixing means in a perspective view.
  • the fixing means have a general shape of cylindrical appearance with a circular base.
  • the external part 124 of the support has the appearance of a cup (inverted in FIG. 5) filled with another cup 122 in Celeron, itself filled with a honeycomb material 123 forming the internal part.
  • the felt 110 is positioned on the material 123. It is preferable to place a thin sheet of polyimide between the felt and the honeycomb part to avoid damaging the felt blade.
  • This felt is slightly put in compression by the pressure exerted by the protective layer 150 bonded to the external part 124.
  • the felt has, in its center, a domed shape giving it an elasticity effect.
  • a thin interlayer sheet 140 (FIG. 4) (not shown in FIG. 5 but which can be the substrate of the detector), the thermal detector 13 and the protective layer 150.
  • the detector must have a low heat capacity. It may be a surface temperature detector formed of a sensitive element such as a resistive layer deposited for example on a substrate formed of a thin sheet of polyimide by a thick layer or thin layer technique, or d 'a resistive layer maintained by gluing for example. It can also be sensitive elements such as surface thermocouples formed, for example, thin or thick layers deposited by appropriate techniques.
  • the thin sheet used must be able to withstand temperatures of the order of 100 ° C. without being deformed and even above it because of the heating generated by the soleplate of the iron. The thin sheet must have a sufficiently low heat capacity so as not to disturb the temperature measurement. Thin sheets of polyimide or Teflon 20 to 100 micrometers thick are suitable for this use.
