Problems solved by technology

[0007] As soon as an attempt was also made to print coloring patterns on anodized aluminum substrates, it quickly became apparent that due to multiple operations of the iron, the coloring patterns did not adhere permanently enough, so that in practice no printed coloring patterns were found due to quality defects anodized aluminum base

Embodiment Construction

[0028] figure 1 The surface 11 of the iron base 10 of the steam iron 1 is schematically shown, which is opened by openings 13 for the passage of steam.

[0029] The surface 11 of the substrate 10, which is at least designed to come into contact with the item to be ironed, is made, for example, of rolled aluminium, which is then electrolytically oxidized. In this case, a thin native oxide layer forms already after a short time in air due to the high affinity of aluminum for oxygen. The process ends after a few months and forms an oxide layer so thick that oxygen diffusion is no longer possible. The layer then reaches a thickness of about 0.05 μm and does not expand any further. However, smaller layer thicknesses do not provide sufficient protection. Therefore, the aluminum is protected on the surface 11 with a thick aluminum oxide layer, which is called ELOXAL (electrolytic aluminum oxide) in German, by anodizing in the electrolyte. The method is technically known specifica...

Abstract

The present invention relates to an iron soleplate (10) and to a method for the production thereof, in particular for a steam iron (1), the surface (11) of which provided for placement on objects to be iron consists of anodized aluminum and / or is coated with an anodized aluminum layer. In order to improve the ironing and gliding properties, a raised enamel graphics element (20) is applied to the anodized aluminum surface (11), which element can preferably contain color pigments of a silicate dye, in which in particular the silicon components were replaced with aluminum. The present invention surprisingly improves the prior art of iron soleplates (10), wherein at least the surface (11) consists of anodized aluminum.

Description

technical field [0001] The invention relates to an iron base, in particular for a steam iron, and a method for producing the same, the surface of which is intended to be applied to an object to be ironed made of anodized aluminum formed and / or covered with an anodized aluminum layer. Background technique [0002] It is known to have iron bases made of metal, the surface of which is provided for application to an object to be ironed is polished. Because it proceeds from this: the best method for obtaining high ironing quality consists in using a substrate whose surface roughness is as small as possible in order to obtain a good heat transfer between the substrate and the object to be ironed and at the same time reduce Small coefficient of friction, which improves the "slide" of the iron on the object. [0003] However such polished substrates are prone to scratching or spotting, especially when the substrate is made of aluminum or covered with an aluminum layer. [0004] T...
