    percentage of defective products. It is also possible to advantageously dispense with light shielding elements to shield the light of a control panel, as well as to increase the comfort of use. The section of the raw plate can be made rough in the process step, for example, by grinding, by sandblasting, by Bristle Blasting and / or by acid treatment. Also, the section of the raw plate can be coated in the process step and / or in a subsequent process step, for example, by anodizing, by electrophoresis and / or with an anti-reflective coating.
    Other advantages are taken from the following description of the drawing. Two embodiments of the invention are represented in the drawing. The drawing, description and claims contain numerous features in combination. The person skilled in the art will consider the characteristics advantageously also separately, and will gather them in other reasonable combinations.
    They show:
    Fig. 1 a top view on an exemplary household appliance as
    cooking field with a household appliance device, Fig. 2 a sectional representation through a part of the appliance device
    domestic with a partially rough armor plate, with a field plate
    of cooking, and with a light source, and Fig. 3 a sectional representation through a part of another apparatus device
    domestic with a partially coated shield plate, with a plate
    cooking field, and with a light source.
    Figure 1 shows a domestic appliance 10a made as a cooking appliance, in a schematic representation. In this case, the domestic appliance 10a is made as a cooking field.
    The domestic appliance 10a has a domestic appliance device. In this case, the home appliance device is made as a cooking field device. The home appliance device comprises a heating unit (not shown). The heating unit is intended to heat at least one cooking battery (not shown). For this, the heating unit has at least one heating element (not shown). In this case, the heating element is made as an inductor. In addition, the home appliance device has an electronics (not shown).

    In addition, the home appliance device comprises a shield plate 20a (see Figure 2). The shield plate 20a is flat and is made in one piece. In this case, the shield plate 20a is made as an aluminum plate. The shield plate 20a is made as a base plate 24a and is arranged between the heating unit and the electronics. In this case, the shield plate 20a is arranged on top of the electronics being observed in the direction of the force of gravity. In addition, the shield plate 20a is disposed below the heating unit being observed in the direction of the force of gravity. In the installation position, the main extension plane of the shield plate 20a is arranged perpendicular to the direction of the force of gravity. Alternatively, a shield plate could be composed of several components. In addition, a shield plate could be composed of a material other than aluminum, in particular an alloy, advantageously, an aluminum alloy, a copper alloy, an iron alloy and / or a Mu-metal, and / or a metal, advantageously, copper and / or iron.
    The shield plate 20a is intended to electromagnetically shield the electronics. In this case, the shield plate 20a shields the electronics against an electromagnetic field generated by the heating element. In addition, the shield plate 20a is provided to support the heating unit.
    The home appliance device further comprises a cooking field plate 12a. The cooking field plate 12a is made in one piece. In this case, the cooking field plate 12a is made as a ceramic hob. The cooking field plate 12a is arranged approximately or exactly parallel to the shield plate 20a. In the present case, the cooking field plate 12a is disposed above the shield plate 20a in the direction of the force of gravity. The cooking field plate 12a is intended to place the cooking battery on top of it and has a control panel 16a. In at least one operating state, the control panel 16a is provided for the user to direct the domestic appliance 10a. The area surrounding the control panel 16a does not have a light shielding element that is provided at least to shield the light from the control panel 16a.
    The household device also has a light source 18a. In this case, the light source 18a is made as a light-emitting diode (LED). In Figure 2, it can be seen that the light source 18a is disposed between the cooking field plate 12a and the shield plate 20a. The light source 18a is fixed to the shield plate 20a. In at least one operating state, specifically, in an operating state of

    heating, the light source 18a is provided to illuminate through a partial section of the cooking field plate 12a. Alternatively, a home appliance device could present multiple sources of light.
    In order to limit the lighting of the cooking field plate 12a effected by the light source 18a, the home appliance device has an essential or totally opaque coating 14a. The coating 14a covers the cooking field plate 12a at least partially on a side directed towards the shield plate 20a. The coating 14a covers another partial section of the cooking field plate 12a made differently with respect to the partial section of the cooking field plate 12a. The coating 14a is provided to prevent an internal area of the domestic appliance 10a made as a cooking field from being observed through the cooking field plate 12a. In addition, the coating 14a is provided to prevent the multiple reflections of light between the cooking field plate 12a and the shield plate 20a being visible. However, the coating 14a may have defects, namely holes, in the context of conventional manufacturing procedures.
    A section 22a of the shield plate 20a is provided to significantly attenuate at least the regular reflection of the light. For this, section 22a has a rough surface. Section 22a has a surface with an average roughness of at least 1 µm. The surface causes at least partially the attenuation of regular reflection, so that particularly intense reflections can be prevented. In this case, the surface allows diffuse and / or irregular reflection.
    Figure 2 also shows an example of the evolution of light beams in an intermediate area between the cooking field plate 12a and the shield plate 20a. A first beam of rays 28a emitted by the light source 18a crosses the intermediate area in a first direction. The cooking field plate 12a causes by regular reflection the transition of the first beam of lightning 28a to a second beam of lightning 30a. The second beam of rays 30a crosses the intermediate area in a second direction. The second direction encloses with the cooking field plate 12a the same angle as the first direction with the cooking field plate 12a. The rough surface of section 22a causes by irregular and / or diffuse reflection the transition of the second beam of rays 30a to multiple third beams of rays 32a. The third beams of rays 32a have different directions from each other. Therefore, the third beams of rays 32a affect different partial sections of the coating 14a. If the coating 14a has a defect, in particular a hole, the third beams of rays 32a pass through the field plate of

    12a cooking by different points. In this way, the light diffusely reflected in the shield plate 20a is uniformly distributed by the cooking field plate 12a. In addition, the light emitted by the light source 18a is prevented from moving in a directed manner. Also, intense reflections on the cooking field plate 12a and on the shield plate 20a are avoided.
    In Figure 3, another embodiment of the invention is shown. The following description is essentially limited to the differences between the examples of embodiment, where, in relation to components, characteristics and functions that remain the same, the description of the embodiment of figures 1 and 2 can also be referred to. For differentiation of the exemplary embodiments, the letter "a" of the reference symbols of the embodiment example of Figures 1 and 2 has been replaced by the letter "b" in the reference symbols of the embodiment example of Figure 3. In in relation to components indicated in the same way, in particular, as regards components with the same reference symbols, it is also possible to refer basically to the drawing and / or to the description of the embodiment of figures 1 and 2.
    In this case, a section 22b of a shield plate 20b comprises a coating 26b. The coating 26b causes at least partially the attenuation of the regular reflection.
    The coating 26b is made as an aluminum oxide layer. Section 22b has a maximum reflection coefficient of 50%. In this case, section 22b has a maximum reflection coefficient of 0.3%. Alternatively, the coating could be partially or completely composed of aluminum hydroxide.
    In this case, the coating 26b of section 22b causes the partial absorption of a second beam of rays 30b. In this way, it is partially prevented that the light emitted by the light source 18b continues to move in a directed manner. In addition, the coating 26 causes by regular reflection the transition of a non-absorbed part of the second beam of rays 30b to a third beam of rays 32b. The third beam of rays 32b crosses the intermediate area in a third direction. The third direction encloses the same angle with the coating 26b as the second direction with the coating 26b. If the third beam of lightning 32b strikes a defect, in particular a hole, of a coating 14b, the third beam of lightning 32b then passes through the cooking field plate 12b. The third beam of rays 32b has an attenuated intensity with respect to the first beam of rays 28b emitted by
