Definitions

  • the invention relates to a steam iron of the type explained in the preamble of claim 1.
  • a steam iron is known from DE-GM 72 00 080, in which a meandering channel system for the steam has been incorporated in the vicinity of the iron sole surface.
  • this channel system additional insert elements are inserted which, in conjunction with the meandering steam guide, are intended to assist the separation of water droplets from the steam.
  • this arrangement is not sufficient to provide a completely dry steam.
  • the invention is therefore based on the object of providing a steam iron with which essentially complete removal of water droplets can be achieved as required.
  • the inventive design of the steam control system creates a type of steam cyclone in which the steam flow is forced into a vortex, whereby the heavier water droplets are thrown outwards against the wall by centrifugal force and the lighter steam can escape in the middle of the vortex.
  • the area of the ironing sole which comes into contact with the steam is enlarged, so that water droplets which have been ejected can be evaporated again immediately. This further improves the drying effect of the steam control system according to the invention.
  • Claims 3 and 4 relate to particularly preferred structural configurations of the embodiment according to claim 2.
  • the water droplets are withdrawn from the vortex flow and evaporated again by the action of heating the iron.
  • Claims 6 and 7 describe particularly preferred structural designs of the water droplet trap.
  • the arrangement of the heater according to claim 8 supports the re-evaporation of the ejected water droplets.
  • the water separation is further improved by the configuration according to claim 9.
  • the degree of water removal can be varied depending on the requirements.
  • the steam iron according to the invention is particularly simple and straightforward to manufacture.
  • Fig. 1 is a steam iron designated as a whole with 1 with a housing 2, a handle 3, and control and regulating means 4, e.g. for the temperature.
  • An electric cable 5 and a steam supply line 6 are arranged on the rear of the steam iron 1.
  • the aforementioned parts are only drawn schematically, since their design is not relevant to the invention.
  • the ironing sole 7 consists of three layer parts 9, 10 and 11, the first layer part 9 having the ironing sole surface 8, the third layer part 11 abutting the housing 2 and the second layer part 10 being arranged between the first and third layer parts 9 and 11.
  • the steam supply line 6 opens in the interior of the first layer part 9 into a first supply channel 12.1.
  • the first feed channel 12.1 opens tangentially into a first recess 13.1, which has a cylindrical wall.
  • a second feed channel 12.2 is arranged in the immediate vicinity of the first cylindrical recess 13.1, which in turn opens tangentially into a second recess 13.2.
  • a total of nine recesses 13.1 to 13.9 with the associated feed channels 12.1 to 12.9 are arranged in the drawing.
  • the dimensions and the number of recesses 13 and the supply channels 12 can be varied according to the available space.
  • each recess 13.1 to 13.9 contains an elevation 14.1 to 14.9.
  • each of the elevations 14 is designed as a truncated cone.
  • the base diameter of the truncated cone is smaller than the base diameter of the recess 13 on the side facing the ironing sole surface 8.
  • the elevations 14 are aligned coaxially with the recesses 13 and correspond in height to the depth of the recesses 13 in the layer part 9.
  • the feed channels 12 are designed as slots which also extend over the entire depth of the recesses 13.
  • a distribution channel 15 which is connected to outlet nozzles 16 emerging on the soleplate surface 8.
  • a horseshoe-shaped heater 17 which should be brought as close as possible to the recesses 13 in order to ensure optimal heating of the walls of the recesses 13 and the elevations 14 and thus optimal evaporation of the condensate being ejected.
  • the heater 17 is connected to the electric cable 5.
  • the feed channels 12, the recesses 13 and the distributor channel 15 are arranged at the bottom of a depression 18 which has been worked into the first layer part 9 on the side facing away from the ironing sole surface 8.
  • the recess 18 is so deep that the layer parts 10 and 11 can be accommodated. From the recess 18 there are only fastening bases 19 for the control means 4 and pins 28 for centering the layer parts 10 and 11 and for abutment of the housing 2.
  • the layer part 10 has an outer shape corresponding to the recess 18.
  • the center holes for plugging onto the pins 28 are from an overview lightness not drawn.
  • the layer part 10 has a multiplicity of through-bores, one part of the bores shown being designed as outlet channels 20 and a second part of the bores being part 21 of the feed channels 12.
  • the outlet channels 20.1 to 20.9 are arranged in such a way that their central axes are aligned coaxially with the central axes of the respectively assigned recess 13.1 to 13.9.
  • the diameter of the outlet channels 20.1 to 20.9 is larger than the smaller top surface of the frustoconical elevations 14.1 to 14.9 and smaller than the diameter of the recesses 13.1 to 13.9, so that the recesses 13 are covered by the layer part 10 except for an annular slot around the elevations 14 .
  • the bores 21 are arranged such that they are located above the end of the feed channels 12 facing away from the recesses 13.
  • This end of the feed channels 12 is expediently widened cylindrically, the diameter of the cylindrically widened ends of the feed channels 12 being matched to the diameter of the bores 21 and the central axes of the bores 21 being aligned essentially coaxially with the cylindrically widened ends of the corresponding feed channels 12.
  • the remaining part of the feed channels 12 is covered by the surface of the second layer part 10. In the same way, the distribution channel 15 is covered up to the surface of a through hole 22.
  • connection channels 23.1 to 23.8 are incorporated into the surface from the underside of the layer part 11.
  • the connection channels 23.1 to 23.8 are matched to the bores 20 and 21 of the second layer part 10 with respect to their position and dimensions such that they each connect between an outlet channel 20 of a recess 13 upstream in the steam flow direction and a feed channel 12 of a recess 13 downstream in the steam flow direction create.
  • the connecting channel 23.1 establishes a connection between the outlet channel 20.1 of the recess 13.1 via the bore 21.2 to the supply channel 12.2 of the recess 13.2.
  • the other connecting channels 23.2 to 23.8 are arranged in the same way.
  • a further connection channel 24 is arranged, which covers the bore 22 at its other end and thus a connection between the last recess 13.9 and the distribution channel 15 with the Steam outlet nozzles 16 produces.
  • two internally threaded lugs 25 are provided, which are used to fasten the iron soleplate 7 to the housing 2.
  • recesses 26 can be seen, which are designed as circular cylinders with a flat bottom.
  • a water droplet trap 27 designed as a blind slot opens into one or more of the cylindrical recesses substantially diametrically and in the opposite direction to the opening of the corresponding feed channel 12.
  • the dimensions and the position of the water droplet traps can be varied according to the available space. It is important, however, that the feed channels 12 and the water droplet traps 27 each open into the recesses 26 in the opposite direction, the outlet points in the steam flow direction being as far apart as possible, so that the steam has to cover the largest possible circular path before it reaches the outlet point of the water droplet trap 27 reached.
  • the water droplet traps 27 are also slit-shaped and extend over the entire height of the cylindrical recesses 26.
  • the heater 17 is brought as close as possible in particular to the water droplet traps 27 in order to optimally vaporize the water droplet traps To ensure 27 accumulating condensate.
  • the layer part 10 is of course designed so that the water droplets are covered upwards.
  • the diameter of the outlet channels 20 thus only has to match the size of the diameter Recesses 26 are matched. Otherwise, the layer parts 10 and 11 of the first exemplary embodiment can be adopted unchanged.
  • the water droplets which have been ejected are evaporated relatively quickly on the wall surface which is enlarged by the elevations and heated by the heater 17, so that they get back into the steam flow as steam.
  • this is Condensate is first collected in the water droplet traps 27 and evaporated there by a longer residence time in contact with the heated, likewise enlarged wall area.
  • the steam conducted in an analogous manner through all the recesses 13 and 26 then passes through the connecting duct 24 and the bore 22 into the distribution duct 15 and is directed there through the steam outlet nozzles 16 onto the material to be ironed.
  • the production of the steam iron according to the invention is considerably simplified by the formation of the iron sole in three layer parts.
  • the ironing sole can also be manufactured in the usual way as a one-piece casting with bores and threaded plugs or in any other way.
