Definitions

  • the present invention relates to a steam iron with a water tank for Supply of an evaporator chamber with water, the in the evaporator chamber supplied water can be converted into steam, and with at least a first and a second steam outlet opening can be connected, a heating element for heating of both the evaporator chamber and an iron soleplate, the Iron sole has an ironing surface and at its front end in the direction of movement has a bow tip and the first steam outlet opening is adjacent to the Bow tip is arranged so that the steam in the area next to the bow tip spreads.
  • a steam iron is known from SU 1201376 A, which has a hose line is supplied with steam from an external steam generator and with one second line of electricity to the heating element for heating to the soleplate fed becomes.
  • the external steam generation source is usually a Generated vapor pressure of about 200 kilo-pascals, which corresponds to a vapor pressure that is about 1000 times greater than a steam pressure in conventional household irons with integrated water tank and drip valve.
  • the soleplate of this Steam iron has a gutter that is substantially parallel to the outer contour the soleplate and immediately adjacent to it on all sides of the iron runs, so that the steam to the front in front of the temple tip, to the back to the The tip of the bow faces away from and exits on both sides.
  • the steam is over the Steam pipe passed into a feed channel, the direction of flow of which is almost perpendicular to the ironing material opens into the circumferential channel.
  • a much more compact steam iron for normal household use is known from DE-OS 4133295 A1.
  • a water tank in the iron is integrated, and a heating element heats both the soleplate and the iron a first and a second evaporator chamber.
  • a drip valve Water from the water tank into the first evaporator chamber evenly fed so that the vapor is essentially due to atmospheric pressure and gravitational force a steam pressure of approximately 100 to 200 Pascals from steam outlet openings below of the steam iron emerges.
  • a piston pump can also be operated via an operating button operated, which sucks water from the water tank and into the second Evaporator chamber injects so that this vapor due to the pump pressure slightly higher pressure from an opening about 1.3 cm above the ironing surface and arranged adjacent to the temple tip, exits.
  • This generated with a piston pump Surface steam impact is commonly referred to as a "jet function”.
  • this "jet function" for smoothing particularly difficult to access areas is very suitable, especially when the soleplate is lifted off relative to the items to be ironed, however, a permanent surface steam function is only possible by constant pumping is. Furthermore, only an area around the tip of the iron is vaporized, the Vapor does not spread near the surface due to turbulence.
  • a steam iron of the type mentioned at the outset is already known from US Pat. No. 3,722,117 known that a heating element for heating both the soleplate and one Has evaporator chamber, and is provided with a drip valve to gradually Feed water from the water tank integrated in the iron into the evaporator chamber.
  • the evaporator chamber can be actuated by either the second steam outlet opening for steam under the iron or with the first steam outlet connected for surface steam. According to this known embodiment, accordingly only one of the two steam functions surface steam or steam under the Irons can be selected.
  • Another disadvantage of this embodiment is in that the steam due to the valve mechanism in the steam line very narrow, winding path to the first steam outlet, so that the steam spreads only in an area immediately in front of the temple tip.
  • the steam from the first steam outlet opening hits tissue that is only a few centimeters in front of the iron tip and already through heat radiation starting from the soleplate is preheated, so that the condensation properties the steam on the ironing goods are not optimal.
  • This effect will reinforced by a quick ironing movement with further reduced steam spreading.
  • the narrow steam path and the valve mechanism to the first steam outlet opening susceptible to constipation due to gradually depositing lime particles.
  • the first steam outlet opening Similar to DE-OS 4133295 above the soleplate and only at the tip of the iron arranged so that a lot of escaping steam is also on the housing of the Iron itself precipitates and a not a small proportion of the total steam the first steam outlet is useless as a high cloud of steam in front of the iron hovers, and condenses in the air, with the additional risk of scalding the Hands of the operator is raised.
  • the first and the second steam outlet opening are advantageously in the soleplate of the iron trained so that the steam spreads very close to the surface because today's iron soles usually have a height of less than 10 mm and so that the second steam outlet opening arranged in the soleplate for the Surface steam to less than 10 mm above the height relative to the ironing material or Ironing surface of the soleplate preferably at a height of less than 5 mm emerges in the ironing position relative to the ironing surface.
  • Another impact of the arrangement The first and second steam outlet opening in the soleplate is that the The soleplate of the iron is automatically sufficiently hot so that there are no condensation drops can form at the outlet opening without additional parts attached would have to be in thermal contact with the sole.
  • first and second steam outlet openings are connected in a pressure-equalizing manner, so that in the event that one of the two steam vents or groups is closed by steam outlet openings by thick fabric to be ironed or at least the applied steam pressure is reduced, via the other steam outlet opening self-regulating more steam escapes.
  • the first and the second steam outlet opening are advantageously independent of the ironing material in connection.
  • This is the pressure-equalizing connecting line or connecting groove between the first and second steam outlet opening dimensioned or designed such that even with very soft fabric of the ironing material and thereby deeply pressing the steam iron into the ironing material a pressure-equalizing steam connection between the first and second steam outlet openings given is.
  • the steam connection is pressure equalizing, that preferably no valve is interposed.
  • the second steam outlet opening arranged within the substantially flat ironing surface, so that by the second steam outlet opens the steam under the steam iron and the ironing material is moistened under the steam iron. It is therefore constantly on simultaneous operation of conventional steam under the steam iron and Surface steam through the first steam outlet next to the steam iron possible, so that a significant improvement in the smoothing result after just one time Ironing is given.
  • the ironing material is caused by the surface steam preconditioned from the first steam outlet opening very close to the surface and then conventionally smoothed by ironing.
  • first steam outlet opening and / or the second steam outlet opening in uninterrupted connection to the evaporator chamber.
  • the nominal steam flow rates can thus be achieved under all actual ironing conditions to be kept.

  • Another just here The embodiment shown provides that the pressure-equalizing connection between the first and second steam outlet opening and / or the connection to Evaporator chamber not in the ironing surface of the iron soleplate but in the one above it Body which receives the heating element is formed. By this measure is absolutely ensured that this steam connection is not interrupted by the ironing material can be.
  • This solution is especially heavy for ironing soles deformable materials such as Stainless steel or relevant for iron soles that a flat ironing surface with no or as few depressions or interruptions as possible provide the ironing surface or the flatness of the ironing surface.
  • an imaginary center line closes first and second steam outlet opening through the groove with an imaginary line of symmetry through the temple tip and the middle of the temple surface at an acute angle, so that the steam emerging from the first steam outlet opening in the direction of movement is directed sideways in front.
  • the course of the groove defines the direction of the Steam outlet for an area around the temple tip or around the front half of the Iron around tight.
  • the opposite edge of the soleplate forms the groove between the Steam outlet openings preferably in the form of a V or W.
  • second steam outlet openings are provided, which are essentially V-shaped the tip of the V are arranged facing the iron tip, so that the iron can be easily moved or rotated.
  • the first steam outlet opening is formed by a bevel on the edge of the ironing surface.
  • the bevel preferably has only an angle between 2 ° and 10 ° relative to the material to be ironed, so that the steam emerging from the first steam outlet opening is very close to the surface is directed.
  • the flatness of the beveled surface has a rounded shape also the advantage that a defined, small exit angle of the steam from the first steam outlet opening with little or no undesirable steam direction components up to the operator is reached.
  • the bevel only extends so close to the tip of the iron that the flat iron surface of the soleplate up to Extending the temple tip and around the temple tip, the first steam outlet opening is arranged adjacent to this area. This leaves one Fine temple tip despite the adjacent bevel on the two adjacent sides of the soleplate edge preserved, the unchanged for particularly difficult to access Areas, e.g. around buttons, is usable. Because the bevel, however Extending close to the temple tip ensures that a surface steam in there is a larger area in front of the temple tip.
  • first steam outlet opening above the ironing surface and on the side of the Iron soleplate is designed, on the one hand, is a very flat steam outlet for very Near-surface steam is possible, on the other hand, the steam outlet opening is through the Iron sole itself formed so no condensation drops around the first one Lower the steam outlet opening, with the risk of "closing" the first Steam outlet opening hardly exists.

This tendency is sufficient to ensure constant pressure equalization Connection between first and second steam outlet opening independent to ensure of the ironing material.
  • the relatively small angle 44 gives a steam flow direction before that a very near surface spread of surface vapor enables.
  • FIG. 12a shows, as already described at the beginning, an iron soleplate 12 in which in are conventionally arranged second steam outlet openings.
  • steam outlet openings 18 are only shown in FIG. 12b shown side view of the soleplate recognizable, since they are spaced apart side slits or other, e.g. B. circular openings in the bent Sidewall of the soleplate are formed.
  • This embodiment ensures a conventional constant ironing surface, as in previous ones Iron is also the case, with the peculiarity that surface steam is still through the first steam outlet openings 18 can emerge laterally along the outer contour.
  • the first steam outlet openings 18 are, starting from the temple tip 20, in the front third of the soleplate 12, with no slot opening being formed in the area directly at the temple tip should be to avoid getting caught with the ironing material. Nevertheless, by the The first steam outlet opening 18 closest to the bow tip ensures that the surface steam at the present steam pressure also up to just before Bow tip 20 spreads.
  • Fig. 12c - a partial section through the shoe and the soleplate - is the pressure-equalizing connection between the first and given second steam outlet opening in that 13 grooves, channels or Slots or the like are formed so that the first steam outlet openings 18th are in steam connection with the steam distribution chamber 16.
  • FIG. 13 shows a perspective top view illustration of an iron shoe 46 can be placed on a conventional steam iron. So it is possible to go through Place the iron shoe 46 on the iron sole firmly attached to the steam iron to provide an iron that additionally has first steam vents for surface steam.
