Description

The invention relates to a method for producing a component for a household appliance arrangement, in which the component is formed on a surface so that it has a first color. Furthermore, the invention relates to a component, which is produced according to the method, as well as an arrangement with a built-in furniture, a household appliance and a component according to the invention.

It is known that in a built-in furniture installation niches are formed, in which a household appliance, such as an oven, is positionable.

Depending on the size of the household appliance, more or less large gaps form towards the edge of the built-in furniture, which are covered by strips. Due to the different configurations and materials, optical effects occur here which make it difficult to find suitable strips without undesired optical cracks and irregularities occurring.

There are known designs, components which should have different optical effects to brush with two different paints. It is necessary in a complex manner to cover the area in each case, which should not be provided with the currently applied paint. This usually leads to difficulties in terms of generating clean boundary edges, so that the two applied paints flow into each other not insignificant and thus just at the transition very blurred color contours occur that can not produce clean separate formed with different optical effects areas. The entire component therefore acts at this point not only inferior quality, but also reveals an adverse manufacturing process.

From the FR 2 889 544 A1 For example, a method of decorating a workpiece with two or more colors is known. A coloring of the workpiece is here first by a anodic oxidation is achieved. A bleach decolorizes a certain surface area, resulting in a two-tone color.

The GB 2 071 153 describes a process for manufacturing a two-color polyhedral aluminum body. The aluminum body is first dark anodized, then a dark anodized mechanically partially removed and applied a lighter Eloxalschicht.

The JP 2001 219 705 describes a method for producing a two-tone rim for two-wheelers. In this case, a color layer is partially removed and a transparent layer applied, which covers both the remaining ink layer and an exposed surface.

The WO 2011/060934 A1 describes a method for manufacturing vehicle wheel components. There two color layers are applied and removed at least one color layer in a portion of the wheel by mechanical processing.

The US 2008/241478 A1 Finally, discloses a method for producing a decorative object in which a pattern is cut into a color layer with a laser beam. It is also envisaged that a further color layer lying below said ink layer will be exposed.

The EP 1 229 153 A2 Finally, a method of manufacturing a front panel for a microwave oven is described.

It is an object of the present invention to provide a method for producing a component for a household appliance arrangement, such a component as well as a corresponding arrangement in which two areas of the component designed differently with optical effects are clean with respect to their optical effect to delimit each other.

This object is achieved by a method, a component and an arrangement according to the independent claims.

In the method according to the invention for producing a component for a household appliance arrangement, the component is formed on a surface in such a way that it has a first coloration. On the surface, a color layer is at least partially applied, which has a different color for the first second color, wherein the color layer is then removed again at a specific surface area of the surface. For such a procedure, a component can be produced, which has two surface areas arranged adjacent to one another, which generate different optical effects, wherein these surface areas can then be sharply separated, so that the different optical effects with respect to the boundary regions between the two surface areas different colors clearly appear and are recognizable.

In this case, the specific surface area is covered after the removal of the color layer with a transparent and preferably optically neutral with respect to a coloring material layer, wherein the material layer is a non-retaining material on the ink layer. On the one hand, this procedure covers the exposed zone or the area of the component in a protective manner, while still leaving the sharp contours very sharp with regard to the two different optical effects with respect to the two colorations. Since the layer of material on the color layer is non-sustained, the color layer is not adversely affected in terms of its optical effect just at the boundary to the specific area by the color layer was removed, so here, too, no dilution of the optical effects with respect to the two colorations occurs.

Preferably, the color layer is applied over the entire surface. This is advantageous in that it is not necessary to mark individual surface areas beforehand by means of adhesions or the like. The component can be generated very uniformly and also with a relatively equal thickness of the first color layer, so that the uniformity of the optical effect of the second color is achieved.

It is preferably provided that the color layer is removed again at the specific surface area by milling or by grinding or by laser processing.

On the one hand, this allows a very precise areal removal, so that a sharp edge between the two surface areas with the different optical colors can be achieved.

It is preferably provided that the color layer in the specific surface area is completely removed to the surface. The optical effect formation achievable by the first coloring of the component can then be achieved again completely over the entire exposed surface area. Distortions of the optical effect by still small residual thicknesses of the ink layer on the component in this specific area can be avoided.

It is preferably provided that a paint is applied as the material layer. Likewise it can be provided that the material layer is produced by anodizing. It can be provided that the surface of the component is ground or brushed. A structuring with mutually parallel grooves is possible. The optical effects can be further favored.

It is particularly advantageous if the component is made of metal or the surface has a corresponding metallic structure. This can then be sanded or brushed, so that corresponding optical effects appear in appearance.

The component may be made of aluminum, for example. This then gives a metallic optical impression. This then applies in particular to the surface area of the surface which has been freed again from the color layer after application of the color layer and is thus exposed, if appropriate except for an additionally applied, the optical metallic impression not falsifying material layer, for example in the form of a transparent lacquer ,

It can also be provided that, for example, a black anodization is produced over a milled aluminum surface area as the color layer. By removing this black anodized color layer area in a specific surface area, a component is then created which has two adjoining areas separated by a sharp optical boundary, one of which has a first metallic color and the second has a black color and corresponding optical effects the consideration of the component are generated and separated by a sharp edge and are perceptible.

Likewise, a gray lacquer can be provided, which then discharges the anodized.

This can be provided with respect to a color layer or, however, also with regard to the surface design of the surface area of the component exposed by the color layer.

On the milled aluminum surface area, which has the first color, then a transparent anodized can be applied.

Such a transparent anodized material can also be produced in the surface area of the component which is freed of the color layer, above a polished aluminum area, which is then symbolized by a brushed aluminum effect. A black lacquer may be provided in the surface area formed with the color layer, with the anodizing being carried out.

Preferably, a front strip is produced as a component, which is designed to be mounted in a space between a household appliance in an installation niche and a built-in furniture adjacent to the built-in furniture. In particular, a front side of the component is generated in areas with the first color, in particular with a metallic color, and partially generated with the second color, preferably having a black or gray optical effect.

Furthermore, the invention relates to a component for a domestic appliance arrangement, which is produced according to the method according to the invention or an advantageous embodiment thereof.

Moreover, the invention also relates to a household appliance arrangement with a built-in furniture, which has a Einbaunische, in which a household appliance is arranged, and having an inventive component or an advantageous embodiment thereof. The component is designed as a front strip and arranged between the household appliance and an edge of the built-in furniture which limits the installation niche.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 a household appliance assembly 1 is shown, which has a built-in furniture 2, in which a Einbaunische 3 is formed. In the installation niche 3 is designed as a baking appliance 4, for example, a cooking appliance, sunk. The household appliance 4 comprises a control device 6 in a front door 5 at the upper edge.

The household appliance 4 is arranged in the installation niche 3, that between an edge 7 of the built-in furniture 2 and an upper edge 8 of the household appliance 4, a gap is formed by a designed as a component front bar 9 is arranged. The front strip 9 has at least two adjacent to each other and as elongated areas formed surface areas 10 and 11. These are separated only with regard to their optical effects and separated by a quasi-horizontal in the embodiment over the entire length of the front panel 9 extending optical boundary.

To produce the front strip 9, an aluminum structure is provided in the embodiment as a base support. This aluminum structure has a front side 12, which may be formed in sections ground or brushed.

On this first completely metallic looking and with regard to their optical effect correspondingly acting front side 12 then a color layer is applied over the entire surface. This has a different color to the first metallic coloration, which may be black, for example. First, according to the manufacturing method, the front side 12 is then completely covered with the color layer. In the following, in the specific area 11, which is smaller than the area of the front side 12 and which is then intended to produce an optical effect again according to the first coloring, this color layer is again completely removed. This is done by milling or grinding or by laser processing. As a result, a very sharp and in view of the optical effect corresponding acting sharp boundary contour between the surface regions 10 and 11 can be achieved. An optical effect dilution straight at the transition between the surface areas 10 and 11 is thus avoided.

It can then be provided that the specific surface area 11, in which then the first color appearance optically reappears, is coated with a transparent lacquer, which lacquer is materially composed so that it on the color layer, as they still on the surface area 10 is not holding. The sharp optical boundary contour between the surface regions 10 and 11 thus remains, even if paint is applied to the surface region 11.

It can be provided that the color layer is applied by anodizing. Likewise it can be provided that the transparent material layer is applied to the surface area after the removal of the color layer by anodizing.

In Fig. 2 a first embodiment of a front side 12 is shown, wherein here in the surface area 10, a black color layer by anodising over a milled Alulminium, which is the front side 12, is applied. In the surface region 11, which is optically and structurally separated from the surface region 10 by a sharp boundary 13, but nevertheless directly adjoins it, a gray paint is applied by eloxal discharge.

In Fig. 3 is a front view of a front side 12 shown, in which case a gray lacquer is applied as a color layer on the surface area 10, which discharges anodized. On the surface area 11, after the removal of the color layer, a transparent anodized is applied, wherein the surface of the front side 10 in the surface area 11 shows a milled aluminum, so that a corresponding visual impression is produced.

In a further embodiment according to Fig. 4 a plurality of superposed surface areas are formed, in each case a black-looking ink layer is applied by anodizing here in the surface areas 10a, 10b and 10c and in other, freed from the ink layer surface areas 11 a, 11 b and 11 c a transparent anodized on the abraded aluminum surface the front side 12 is applied.

The same is true in the embodiment according to Fig. 5 shown here, wherein here the arrangement of the respective surface areas in comparison to Fig. 4 something varies.

In addition, in all embodiments, further developments can be given to the effect that an at least further surface area is formed which has a third coloration with regard to its optical effect, so that a single component 9 generates three different optical effects with respect to the front strip on its front side 12.
