Definitions

  • the invention relates to an electrically heated iron, namely steam iron according to the preamble of claim 1.
  • an iron soleplate is excluded Aluminum on an electric radiator, also called Heating insert is called and with it in heat conducting Connection is established.
  • Heating insert is also one from the soleplate Steam chamber.
  • Sole made of aluminum.
  • the soleplate is made with a thin steel foil encased or on its underside with an additional Sole plate made of steel, which is a thickness of some Can have millimeters. This coating or casing or have the additional steel sole plate the fundamental disadvantage of being less than aluminum Thermal conductivity.
  • An electric iron is already part of the prior art consisting of soleplate with electric radiator and a hood handle part that is spaced above the soleplate is arranged and in which between the hood of the hood handle part and the soleplate in the area of the iron tip a two-leg spacer is arranged (DE-G 97 17 313.1). At the front upper area of the spacer can be formed a retaining lug, which in the installed state Grips the tip of a hood handle part.
  • the spacer a connection of thermoplastic hood handle parts with metal sole plates without an air gap in the Allow area of iron tip that is normally for the hood portion as a heat shield against that of the soleplate outgoing heat, and thus the disadvantage of the air gap avoids straps between the hood and the soleplate, Bows, buttons, buckles or similar accessories for the ironing material Clamp. So that the spacer the heat shielding function of the air gap to the hood, it is clear that the Spacers are made of poorly heat-conducting material got to.
  • the electrically heated iron with spacer points So with regard to the undesirably strong cooling of the iron tip the same disadvantage as that discussed above known steam iron without such a spacer.
  • a soleplate that is thermally conductive with an electrically heated mass is connected and which is made of a plastic poor thermal conductivity, with one exception the rear of the soleplate with a raised edge Groove that is used to hold the heated mass (US-A-4,233,763).
  • the edge goes into a Elevation with a threaded hole for receiving a fastening screw about. Steam channels end in the heated mass - seen in the longitudinal direction of the iron - at a distance from the elevation.
  • the small bump and the grooved edge are not suitable and are not intended the thermal conditions in the area of the sole tip are noteworthy to influence.
  • the present invention has the object based on an electrically heated steam iron at the beginning mentioned genus uncomplicated to train that in the area the sole tip on the tread of an additional sole plate made of steel or a steel coating of the soleplate No annoying temperature drop occurs when the sole tip heat is removed by ironing. This is said to be in use of the iron for better, faster and more even ironing results to lead.
  • the advantages of coated or with one Covering or an additional sole plate refined tread the iron should be preserved.
  • This task is accomplished through the training of the electrically heated Steam iron according to the characterizing part of claim 1 solved in that the soleplate in the area of the sole tip a thickening of good heat-conducting and good heat-storing Has material.
  • This material is according to claim 5 aluminum, of which the soleplate is also made.
  • a coating of this soleplate with steel, so a material of proportionate to aluminum poor thermal conductivity, or the additional sole plate made of steel does not cause an undesirably large drop in temperature in the sole tip area when ironing, because the delayed due to the low thermal conductivity of the steel Heat transfer between the heating of the iron and the Ironing goods through the good heat-conducting and good heat-storing thickened sole tip is balanced.
  • the thickening made of good heat-conducting and good heat-storing material becomes quick Guaranteed heat delivery to the sole tip, with what even a higher temperature in Area of the sole tip than in the remaining area of the soleplate is achieved.
  • the thickening with two legs is approximately V-shaped when viewed in plan view, the Thigh a steam generator and especially a steam labyrinth at least partially grasp the top of the soleplate, which removes a lot of heat from the soleplate and thus significantly to cool a sub-area the soleplate contributes.
  • the thickening is in one piece molded from the soleplate, which includes that the Thickening made of the same material as the soleplate, especially made of aluminum. A heat transfer problem cannot occur between the soleplate and the thickening.
  • 1 denotes an iron body, of a lower housing and one arranged above this Contains water tank and a handle.
  • an iron soleplate 2 is located on the iron body Aluminum. Between the plastic housing there is an air gap between the iron body and the soleplate 2, which is designated in the area of the sole tip.
  • a heating element 3 In the Soleplate is a heating element 3, of which in Fig. 2 shows a cross section.
  • a steam chamber 4 located above the radiator 3 there is a steam chamber 4, on both sides as a leg adjacent steam boost channels 5 and 6 are arranged.
  • runs parallel to it i.e. to the iron tip towards a steam maze 7, in the bottom of which steam holes 8, 9, 10 through the soleplate and one on the Additional sole plate attached to the underside of the soleplate reach out of steel 11.
  • FIG. 2 From Fig. 2 it can be seen that the steam chamber 4 and that Steam labyrinth 7 covered by a steam duct cover 12 above are, which is also over the steam boost channels 5 and 6.
  • a water valve 13 extends through the steam duct cover 12 the water tank (not shown) into the steam chamber 4.
  • the soleplate 2 has a bug- or plow-shaped thickening 14 on the top view 3 with two legs not designated a part of the steam maze 7 and the steam chamber 4 includes.
  • the thickening consists of the same good heat-conducting Material that also has a relatively high heat capacity has like the soleplate, namely made of aluminum. Due to their shape and arrangement, the thickening causes on the soleplate tip not only that this in time average a higher temperature than without such Has thickening, but it also ensures the desired temperature of the adjacent steam-generating or - guiding elements.
  • the sole of the soleplate which is also one for ironing should have a suitable shape
  • the strength of the Thickening of the soleplate tip and an outer edge 16 starting at first quickly to gradually move towards the back Soleplate 2 fall off, as shown in detail in FIG. 1 and 2 can be seen.
  • the housing of the iron body 1 compared to the increased temperature at the thickening 14 of the To shield the tip of the soleplate is between the top of the thickening and the housing the air gap 15, which is higher and set back compared to the usual air gap between the top of a soleplate and a plastic housing.
