Definitions

  • the invention relates to a steam iron according to the preamble of claim 1.
  • Such a steam iron is known for example from DE-OS 41 33 295.
  • the steam iron described in DE - OS 41 33 295 has two evaporator chambers, one of which is intended to evaporate the liquid which is to be directed as a steam-liquid jet in front of the tip of the soleplate.
  • Claims 2 and 3 show particularly advantageous embodiments of the steam channel with regard to the restrictions that result from the spatial limitation of the iron body.
  • the amount of water to be evaporated in the second evaporator chamber can be easily metered by the pump arrangement on the one hand and on the other hand can be conveyed into the evaporator chamber with a sufficiently large delivery rate so that the evaporation of the latter Water can be done in a relatively short period of time.
  • the steam iron according to claim 6 shows that the moisture content of the steam which emerges from the steam outlet nozzle is adjustable.
  • any local cooling that may occur due to the amount of liquid dropping in and the amount of heat extracted from the iron body due to the amount of liquid dropping in and the amount of heat withdrawn from the iron body due to the evaporation by the separate heating devices are regulated separately can be.
  • Fig. 1 shows a section through part of a steam iron according to the invention
  • Fig. 2 is a plan view of the top of the heatable shoe
  • FIG. 1 shows a simplified illustration of a steam iron 2.
  • a heatable shoe 6 is mounted on a sole 4.
  • Two evaporator chambers are incorporated into the heatable shoe 6.
  • a first evaporator chamber 8 is in flow connection with the liquid container 12 via a liquid line 10 which can be closed by a valve (not shown).
  • line 10 open, liquid flows from container 12 through line 10 to a dropping point 14 in the first evaporator chamber and is completely evaporated.
  • the steam flows through an outlet channel 16 to steam outlet holes 18 in the sole 4 of the steam iron 2 in order to moisten the items to be ironed.
  • a second dropping point 20 is provided, which is in flow connection with the first evaporator chamber. Becomes liquid there fed and in addition to the steam generation at the first dropping point converted into steam and passed through the outlet channel 16, a much higher amount of steam emerges from the steam outlet holes 18 per unit time and moistens the ironed material.
  • the heatable shoe 6 has a second evaporator chamber 22.
  • This second evaporator chamber 22 is elongated in the upper side of the shoe 6, as can be seen more clearly from FIG. 2.
  • the evaporator chamber 22 has a first 24 and a second 26 dropping point.
  • the second evaporator chamber 22 is in flow communication with a steam outlet nozzle 28.
  • the steam outlet nozzle 28 is arranged such that the emitted steam liquid jet strikes the tip of the steam iron and thus moistens the ironing material just before the sole 4 of the steam iron slides over it.
  • the dropping points 24 and 26 are acted upon by a pump arrangement 30 with liquid from the liquid container 12.
  • the pump arrangement 30 has a suction channel 32, through which liquid is conveyed from the liquid container 12 into the drop channel 36 when a pump 34 is actuated.
  • the pump 34 for example a piston pump, is operated by rotating and / or pressing an actuating element 38.
  • the amount of liquid to be delivered can be preselected on the pump 34 by the user of the steam iron, for example by preselecting the piston stroke of the pump. Amounts of liquid between approx. 1 and approx. 7 g liquid per stroke are usual.
  • a distributor device 40 can be inserted into the dropping channel 36. In this distributor device 40, the dropping channel opens into two outlet channels 42, 44.
  • the first outlet channel 42 ends above the first dropping point 24 of the second evaporator chamber 22, the second outlet channel 44 ends above the second dropping point 26 of the second evaporator chamber 22.
  • an adjusting device 46 is arranged on the second output channel 44.
  • This adjusting device 46 here a rotatable pin, which can be screwed more or less far into the channel 44 in order to adjust the flow cross section which limits the liquid passage, is to be operated by the user of the steam iron.
  • Other adjusting devices such as a clamp for constricting a flexible line section of the output channel are also suitable for influencing the division of the liquid flow.
  • the dropping channel 36 leads to the first (and in this case only) dropping point 24 of the second evaporator chamber 22.
  • the second evaporator chamber 22 is between the first evaporator chamber 8 in the center of the shoe 6 and the outer edge 48 of the shoe 6 arranged. It extends from a first end 50 in the front third of the shoe 6, at which the first dropping point 24 is arranged, in a fork shape on both sides of the first evaporator chamber 8 to the rear end of the shoe 6. From a bend 52 of approximately 180 ° in In the rear third of the shoe 6, the second evaporator chamber 22 extends to the tip of the shoe 6 and opens there with its second end 54 directly at the steam outlet nozzle 28.
  • the second dropping point 26 can be arranged at the second end 54 of the second evaporator chamber 22.
  • the first 8 and the second 22 evaporator chamber can be heated separately by separate heating wires (not shown).
  • a vapor-liquid jet is generated by, by actuating the pump 34, drawing a predetermined amount of liquid through the suction channel 32 out of the liquid container 12 and conveying it into the drop channel 36, from where the liquid, usually lime-free water, enters the distributor device 40.
  • the amount of liquid is divided here into two partial flows.
  • a first partial flow passes through the outlet channel 42 and reaches the heated first dropping point 24 of the second evaporator chamber 22.
  • the liquid flows through the elongated, second evaporator chamber 22 and begins to evaporate. Because this evaporator chamber 22 extends long, the water that drips in at the first dropping point 24 is evaporated almost completely.
  • this moist steam can be further heated due to the elongate extension of the evaporator chamber 22 during the movement to the steam outlet nozzle 28 from the side walls of the evaporator chamber 22, so that until the steam outlet nozzle 28 is reached, the water is at least almost completely evaporated. Arrived at the second end 54 of the second evaporator chamber, the first partial flow of the supplied liquid has evaporated completely or almost completely and begins to emerge from the steam outlet nozzle 28. The second partial flow of the liquid is discharged into the emerging steam through the outlet channel 44 to the second dropping point 26.
  • This partial flow is only partially evaporated, a substantial part of the liquid is entrained by the already evaporated first liquid partial flow and passes through the steam outlet nozzle 28 as a finely atomized droplet stream with the steam onto the items to be ironed.
  • the distributor device 40 By adjusting the distributor device 40, the user can preset in a wide range whether the second partial flow of the liquid should be evaporated almost completely, so that a relatively hot burst of steam hits the ironing material, or whether the liquid added at the second dropping point 26 is essentially in liquid Physical state is to be entrained by the steam of the first partial flow, so that a jet of steam-liquid that is heavily enriched and less hot strikes the material to be ironed.
  • the distribution device first delivers the first partial flow of the supplied liquid and only then, when the steam generated thereby reaches the second end 54 of the second evaporator chamber 22, the second partial flow of the liquid onto the second dropping point 26 conducts.
  • This time delay therefore results from the time that the water evaporates at the first dropping point 24 plus the time that results from the flow rate of the steam, namely the time that the steam takes to go from the first dropping point 24 to the second dropping point 26 to arrive.
