Abstract

The steam distribution groove comprises a flat steam bed (11), which is at least 10 mm wide, preferably 20 mm wide. The steam bed is preferably incorporated into the area of a U-shaped heating body (5) held on the iron sole.

Description

The present invention relates to a steam iron with an iron soleplate with a in this trained steam chamber, from which the steam flows in via steam channels a steam distribution groove opens, which is formed on the ironing surface of the soleplate is and has a U-shaped course, the U-bend on the tip of Iron sole is directed.

Such a steam iron is known from DE-41 07 237 A1, the steam distribution groove is formed by a continuous channel, which preferably the Depth of 4 to 8 mm and a width of 2 to 4 mm. At the steam distribution groove are followed by beads running radially outwards towards the tip, which in are arranged approximately at the same distance one behind the other. For cleaning the steam distribution groove it is only necessary to put a cleaning cloth through the groove pull.

The object of the present invention is the ironing behavior in a generic Improve steam iron.

According to the invention this is achieved in that with a steam iron after Preamble of claim 1, the steam distribution groove through a flat steam bed is formed, the width of which is at least 10 mm, in particular approximately 20 mm. in the In the area of the flat and wide steam bed, the soleplate lies only with her Ironing area, which is reduced by the area of the steam bed, directly on one level ground. Due to the design of the steam bed is the ironing required effort due to the reduced support or sliding surface with simultaneous large steam cushion between ironing and soleplate clearly reduced, which without interruption substantially over the entire length of the Iron sole U-shaped steam bed continues the sliding properties and that Improve ironing result. The steam bed is therefore preferably not partially through the ironing surface is interrupted, but actually U-shaped.

The depth of the steam bed is advantageously a few 1/10 mm, in particular 1/10 up to 5/10 mm. This ensures that, depending on the suitable width of the Steam bed on the one hand the ironing material also deeper in comparison to the ironing surface laid bottom surface of the steam bed is smoothed in addition to the ironing surface, and that on the other hand, the steam emerging from the steam outlet openings is sufficient can be distributed over the entire steam bed.

To avoid that the steam laterally between the items to be ironed and the soleplate emerges, the steam bed is spaced from the edge of the iron soleplate arranged.

According to a preferred embodiment are in the bottom surface of the steam bed Beading formed, the steam flowing out of the steam channels in the steam bed to distribute. The beads improve the distribution or filling of the steam bed with steam and preferably direct the steam to areas of the steam bed that are attached to the radiator of the steam iron. It is particularly effective if the beads Direct steam from the edge of the soleplate towards the center. About the steam distribution To make cheap in the steam bed, advantageously flows between each two beads at least partially a steam channel in the bottom surface of the steam bed. In addition, this provides sufficient floor space in the steam bed for smoothing is less deep than the bead bottom surface.

The steam bed is advantageously in the region of a U-shaped soleplate on the iron supported radiator trained. This is the shape and location of the steam bed adapted to that of the radiator.

Below is an embodiment of the invention based on schematic representations Steam iron described.

A steam iron known per se has an iron soleplate 1 as an aluminum casting on. On the side facing the top of the iron is on the soleplate 1 a steam chamber 3 is formed in one piece in a manner known per se, in which the steam required for ironing is generated. The steam chamber 3 is with a lid, not shown, can be closed. In the steam chamber 3 or the soleplate 1 is a tubular heater 5 which extends in a known manner in a U-shape cast for heating the soleplate 1. The U-arm of the Tubular heater 5 on the top of the iron soleplate 1. Furthermore, in the Iron sole 1 steam channels 7 are provided, which arise in the steam chamber 3 Guide the steam down. An ironing surface 9 on the underside of the soleplate 1 is highly polished, but could also use an additional one, for example Provided ironing layer or otherwise processed (Fig. 1, 2).

A U-shaped flat steam bed 11 is formed in the ironing surface 9. A Bottom surface 13 of the steam bed 11 is 3/10 mm below the ironing surface 9 parallel to this. The steam bed 11 has a width of approximately 25 in its two legs mm, the outer edge of the steam bed over its entire length in runs substantially equally spaced from the outer edge of the soleplate 1 (FIG. 1). The inner edge of the steam bed 11 runs essentially parallel to the latter outer edge. In the relatively cold rear area of the soleplate 1 is in the In contrast to the tip section, the formation of a steam bed 11 is dispensed with. The bottom surface 13 of the steam bed 11 predominates in the area of the tip, while in the middle region of the soleplate 1 the surfaces of the bottom surface 13 and Ironing surface 9 are approximately the same size. First steam outlet openings are in the steam bed 11 15 and second steam outlet openings 17 are arranged. During the first Steam outlet openings 15 are formed in the bottom surface 13 of the steam bed 11, are the second steam outlet openings 17 in funnel-shaped beads 19 des Steam bed 11. The beads 19 run at a distance from the outer edge of the steam bed 11 to its inner edge. A beaded base 21 rises from the deepest area the bead 19, in which the second steam outlet opening 17 is arranged, for inner area of the steam bed 11 to the level of the bottom surface 13 of the steam bed 11, the level of the bead base 21 at a distance from the inner edge of the steam bed 11 reached (Fig. 1, 3). With the steam bed 11 is so with the exception of the beads 19 and first steam outlet openings 15 slightly in relation to the ironing surface 9 recessed bottom surface 13 of the steam bed 11 is provided.

The depth of the steam bed 11 is formed in comparison to its width in such a way that also with the bottom surface 13 of the steam bed 11 a smoothing effect of the ironing material in addition to the smoothing effect of the ironing surface 9 can be achieved. On the other hand, it is Depth of the steam bed 11 sufficient to clearly show the forces required for ironing to reduce. The mutual arrangement of first steam outlet openings 15 and second steam outlet openings 17 has a good steam distribution over the width of the Steam bed 11 result. While the first steam outlet openings 15 more external area of the steam bed 11, the second from Steam outlet openings 17 exiting steam through the beads 19 more inside Area of the steam bed 11 out.
