Embodiment Construction

[0029] In the figures, identical or functionally identical elements have the same reference signs.

[0030] figure 1 In , a domestic appliance part 1 is shown in a sectional view, which may be, for example, a control panel. The household appliance part 1 comprises a base body or base 2 which is made at least partially, in this embodiment preferably completely, of plastic. On the top side 3 of the base 2 a marking 5 is produced by means of a laser 4 . In this case, the laser beam 4 melts the plastic material with its laser beam, whereby a plastic foam region 6 is produced which protrudes to the top relative to the surface 3 a in a convex manner. In this way, the marking 5 stands out visually in contrast to the plastic material which has not been treated by the laser 4 .

[0031] Then, in a subsequent step, after the creation of this plastic foam region 6 , the plastic foam region 6 is compressed and thus increased in its density. this is in figure 2 , wherein a compressio...

Abstract

The invention relates to a method for producing a household appliance component (1), in which a base part (2) of the household appliance component (1) is provided, which is formed of plastic at least one a top side (3) and a mark (5) is generated with a laser (4) on the top side (3), wherein a plastic foam area (6) is formed on the top side (3) by means of the laser (4) for the mark (5), wherein the plastic foam area (6) is reduced in thickness (d) and / or increased in density afterwards. The invention also relates to a household appliance component (1).

Description

technical field [0001] The invention relates to a method for producing a domestic appliance part in which a base of the domestic appliance part is provided. The marking is formed on the top side of the base with a laser, wherein the plastic foam area is formed on the top side by means of the marking laser. Furthermore, the invention relates to a domestic appliance part which is produced by means of a corresponding method. Background technique [0002] Document EP 2072478 A1 discloses a method and a household appliance part of this type, wherein the top side is formed from glass or ceramic, and glass or ceramic foam is formed on the top side by means of a laser for marking. [0003] It is known that a large number of materials can be processed by means of lasers. In this case, plastics can also be processed. The laser beam acts on the plastic material and melts it on the top side. Markings can be produced by this method, since for example dark-colored plastics can be disc...
