    regarding the masked surface. Thus, by removing the masking, at least two different surface areas are generated.
    In another advantageous development of the invention, it is envisaged that the coating be cured before removing the masking. In this way, the coating can be prevented from deteriorating.
    In another advantageous development of the invention, the method comprises at least the steps consisting of applying a coating on the base element at least in the area of the information to be provided, and removing one or more parts of the coating to create the first and the second surface areas. In other words, the selected coating is applied first to the combined areas of the first and second surface areas and then removed in the first or second surface area.
    The third aspect of the invention refers to a household appliance, which comprises at least one household appliance component according to the first aspect of the invention and / or at least one household appliance component manufactured by a method according to the second aspect of the invention. The resulting features and their advantages can be drawn from the description of the first and second aspects of the invention.
    In an advantageous embodiment of the invention, it is envisioned that the household appliance is configured as a dishwasher, dryer, washing machine, microwave oven, and / or steam oven. Since the domestic appliance is configured as a domestic appliance that operates with water and / or steam, the display means or means can be used in a particularly simple way to display the information when the water and / or steam accumulate in a specific way, which Any form is available, over the first hydrophilic area (s).
    Other features of the invention are drawn from the claims and the following embodiments. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the embodiments, are usable not only in the combination indicated in each case, but also in other combinations without leaving the scope of the invention. Therefore, variations of the invention are also possible that are not explicitly shown and described in the embodiments but which, however, can be formulated through different combinations of separate features of


    the described embodiments. Variations and combinations of features that do not contain all the features of an independent claim originally formulated are also possible. Next, the embodiments of the invention are described in more detail with reference to the schematic drawings. Here, they show:

    Fig 2 a front view of a household appliance with a display means to provide information;
    Fig. 3 an enlarged view of a door of the domestic appliance of figure 2;
    Fig. 4 an enlarged view of the door during operation of the household appliance shown in figure 2;

    Fig. 6 an enlarged view of the household appliance component of figure 5;
    Fig. 7 a front view of the domestic appliance according to another embodiment;
    Fig. 8 a front view of the domestic appliance of figure 7 at the beginning of its operation;
    Fig. 9 a front view of the household appliance of figure 7 during operation;
    Fig. 10 a front view of the household appliance of figure 7 at the end of its operation;
    Fig. 11 an enlarged view of the household appliance component shown in figure 10.
    Figure 1 shows a perspective view of a household appliance component 1 with a display means 2 to provide information. The display means 2 comprises first surface areas 3 with hydrophilic properties,


    which are surrounded by a second surface area 4 with hydrophobic properties. The first and second surface areas 3, 4 jointly define information, the information shown in Figure 1 being the "SIEMENS" logo. As a consequence of the different hydrophilic and hydrophobic properties, water accumulates on the first surface areas 3 and forms the logo or inscription. Therefore, the display means 2 can be seen as a kind of "watermark logo" applied on the household appliance component 1, which is originally made of stainless steel (initially hydrophilic). The display medium 2 has been produced by masking the letters "SIEMENS" and applying a
    10 superhydrophobic coating on the hydrophilic surface 3 of the household appliance component 1. After removal of the masking, the original hydrophilic surface area 3 is exposed again and attracts water significantly more intensely than the remaining hydrophobic surface area 4.
    This principle can be applied to all types of household appliances that
    15 run on water or steam, such as dishwashers, washing machines, and steam ovens. Table 1 shows different combinations of the first and second surface areas 3, 4 to define a logo based on the initial surface properties of the household appliance component 1.

    Figure 2 shows a front view of a household appliance 5 with a display means 2 for providing information. Figure 2 will be described together with Figures 3 and 4. Figure 3 shows an enlarged view of a household appliance component 1, which is configured as a door of domestic appliance 5, while Figure 4 shows an enlarged view of the door 1 during operation of the domestic appliance 5. The domestic appliance 5, which is configured as a washing machine, is provided with the gate 1 comprising a means of


    2 display in the form of the “BOSCH” logo on its inner surface. The display means 2 has been produced by applying a hydrophobic coating only on the "BOSCH" logo, while the rest of the surface of the door 1 has been masked. As can be seen in Figure 4, during operation of the washing machine 5, the water droplets join on the hydrophilic surface area 3, while the hydrophobic surface area 4 in the form of the logo is at least almost completely without water, thus presenting the "negative" logo.
    Figure 5 shows a perspective view of the household appliance component 1 with a display means 2 to provide a "BOSCH" logo, while Figure 6 shows an enlarged view of the household appliance component 1 of Figure 5. The component of household appliance 1 is configured as a door for a dishwashing machine 5. The display means 2 has been made on the inner wall of the door 1 by masking the "BOSCH" logo and applying a hydrophobic coating on the entire inner surface of the door 1 After removing the masking, the water adheres on the hydrophilic surface area 3 and disperses on the hydrophobic surface area 4.
    Figure 7 shows a front view of the domestic appliance 5 according to another embodiment. The domestic appliance 5 is configured as a steam oven and comprises a household appliance component 1 configured as a steam oven door 5, and which comprises a display means 2 for displaying a "BOSCH" logo on a window of the door 1 .
    The display means 2 comprises a first hydrophilic surface area 3, which is constituted by the uncoated glass surface of the door window. Also, the display means 2 comprises a second superhydrophobic surface area 4 in the form of a logo. As can be seen in Figure 7, the display means 2 is invisible while the steam oven 5 is deactivated or while the humidity level inside the oven 5 is below a predetermined threshold.
    Figure 8 shows a front view of the steam oven 5 at the beginning of its operation. The humidity level inside the steam oven 5 is still below the predetermined threshold, so that water drops begin to form inside the door 1, while the display means 2 continues to be deactivated or invisible.


    Figure 9 shows a front view of the household appliance of Figure 7 during operation. As can be extracted from Figure 9, the logo appears after approximately 2 minutes of steam cooking, that is, after the humidity level inside the steam oven 5 exceeds the predetermined threshold level. Figures 10 and 11 show other front views of the domestic appliance 5 at the end of its operation.
    It is possible to use different coatings to provide hydrophobic or superhydrophobic properties such as, for example, SiO2, fluoropolymers, titanium dioxide, silanes, and all their derivatives.
