    In an advantageous embodiment of the invention, it is envisioned that the domestic appliance is configured as a domestic water carrier, in particular as a dishwasher, washing machine, dryer, water tank, ironing system, coffee machine and / or kettle. Due to the presence of water during the operation of the domestic appliance, the optical appearance of the marking can therefore change from transparent to opaque when wet, and from opaque to transparent if it is dry. Thus, the optical appearance of the marking depends on the presence or absence of water and can be reversibly modified in order to provide information depending on the presence or absence of water.
    Other features of the invention are drawn from the claims, the figures and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures are usable not only in the combination indicated in each case, but also in other combinations, without abandoning the scope of the invention. Therefore, it should be understood that those embodiments of the invention that are not explicitly shown in the figures or explained, but which can be extracted through combinations of features separate from the shapes are also understood and disclosed by the invention. of realization exposed, and that can be generated from these. Therefore, those embodiments and combinations of features that do not have all the features of an independent claim originally formulated will also be considered disclosed. Likewise, those embodiments and combinations of features that transcend or differ from the combinations of features set forth in references to the claims shall be deemed disclosed by means of the embodiments set forth above. The figures show:
    Fig. 1 a schematic illustration of a household appliance component with a base element, on the surface of which a laser marking is generated;
    Fig 2 an illustration of an embodiment of the household appliance component according to the invention, in the dry state of the marking;
    Fig. 3 the household appliance component according to figure 2, in the wet state of the marking;

    - a laser power between 0.5 W and 10 W, for example, 0.5 W, 0.6 W, 0.7 W, 0.8 W, 0.9 W, 1 W, 2 W, 3 W , 4 W, 5 W, 6 W, 7 W, 8 W, 9 W, 10 W, as well as the corresponding intermediate values;
    - a pulse duration between 5 ps and 20 ns, for example, 5 ps, 10 ps, 20 ps, 30 ps, 40 ps, 50 ps, 60 ps, 70 ps, 80 ps, 90 ps, 100 ps, 200 ps , 300 ps, 400 ps, 500 ps, 600 ps, 700 ps, 800 ps, 900 ps, 1 ns, 2 ns, 3 ns, 4 ns, 5 ns, 6 ns, 7 ns, 8 ns, 9 ns, 10 ns, 11 ns, 12 ns, 13 ns, 14 ns, 15 ns, 16 ns, 17 ns, 18 ns, 19 ns, or 20 ns, as well as the corresponding intermediate values; Y
    - a wavelength between 240 nm and 1,064 nm, for example, 240 nm, 290 nm, 340 nm, 390 nm, 440 nm, 490 nm, 540 nm, 590 nm, 640 nm, 690 nm, 740 nm, 790 nm , 840 nm, 890 nm, 940 nm, 990 nm, 1,040 nm, or 1,064 nm, as well as the corresponding intermediate values.
    With the help of such laser marking, it is possible to create a wide variety of 6 markings, including drawings, brand designs, or even create specific messages in some applications.
    The household appliance component 8 can be formed, for example, as a door of a dishwasher, and includes a region 4 that is formed by glass or hob in the embodiment shown in Figure 2. In region 4 a hydrochromatic marking 6, which comprises letters and a symbol in this embodiment. This hydrochromatic marking 6 may, for example, include or be a company logo.
    The hydrochromatic marking 6 is generated by direct action on the surface 7 of the base element 2. Thus, the hydrochromatic marking 6 is generated on the surface 7 of the base element 2 itself by direct action of the laser light on the glass material or the material Ceramic hob Through the action of only laser light, both hydrochromatic marking 6 is generated in its geometric configuration and composition as well as its hydrochromatism.
    The hydrochromatic marking 6 is generated on a surface 7 of the base element 2 directed towards the interior space of a domestic appliance, for example, a dishwasher, in such a way that it comes into immediate and direct contact with the water during the operation of the home appliance


    In Figure 2, the door in region 4 of the marking 6 is shown in an enlarged representation. Here, a state is shown in which the hydrochromatic marking 6 is dry and, therefore, is shown in color, here, in white. Outside of hydrochromatic marking 6, surface 7 is basically transparent as a consequence of its material configuration. In the implementation shown according to Figure 2, hydrochromatic marking 6 includes, in addition to the term "BOSCH", a symbol to the left of it. To the right of this inscription, an area is also formed that is also part of the hydrochromatic marking 6 and forms an opaque curtain. In the embodiment, the hydrochromatic marking 6 is therefore formed by a symbol 6a, letters 6b, and an area 6c.
    Thus, if the hydrochromatic marking 6 is exposed to moisture, for example, steam or water as a reservoir, during the operation of the dishwasher, as illustrated in Figure 3, the hydrochromatic marking 6 becomes transparent.
    In figure 4, in a simplified illustration, another household appliance component 8 is shown which is a container (water tank) for storing a liquid 9. Here, the household appliance component 8 may be a coffee machine component , an iron, or a pressure cooker. The liquid 9 can be water. In this configuration, hydrochromatic marking 6 is formed as an indication of the filling level. Here, a state is shown in Figure 4 in which a high filling level has been reached and, therefore, a relatively large amount of liquid 9 is contained in the household appliance component 8. Here, only a higher value of the marking 6d is not wetted by water or is not in contact with the liquid 9, so that here it is visible and therefore not transparent.
    In figure 5, the household appliance component 8 is shown in a state in which the liquid filling level 9 has been considerably reduced. Here, another value 6e and another value 6f are not in contact with the liquid 9, so that they are also visible and are no longer transparent. In comparison with this, in figure 4, by the contact of the values 6e and 6f of the hydrochromatic marking 6 with the liquid 9, a transparency was given here, so that these elements were transparent and were not recognizable in the figure Four.
    In Figure 6, another embodiment of a hydrochromatic marking 6 is shown which is a symbol of several drops.
    In figure 7, another embodiment of a hydrochromatic marking 6 is shown, which is formed as a symbol and shows a stream of water entering a water tank.


    existing water Through this symbol, the need to fill with a liquid can be illustrated.
    The 6 markings mentioned above offer multiple advantages. There are no adhesion problems, 6 markings can be created immediately on the
    5 base element 2, are very resistant to abrasion, chemicals, or temperature, are very durable, no consumable products are necessary for their production, they can be easily implemented in current and future products, they can be digitally designed, and allow the creation of household appliances with added value.
    Those skilled in the art will understand that, while the present invention has been set forth with reference to the preferred embodiments, various modifications, changes and additions to the previous invention may be made without abandoning the spirit and scope thereof. The values of the parameters used in the claims and in the description to define the process and measurement conditions
    15 to characterize the specific properties of the invention are also included within the framework of deviations, for example, as a result of measurement errors, system errors, weight errors, DIN tolerances, and the like.
