The invention starts from a home appliance system with a home appliance device according to the preamble of claim 1.

An appliance appliance device and, in particular, an appliance appliance plate, with a base body and with a layer unit, which is arranged on one side of the base body has already been proposed. In this case, the base body is configured as a plate unit. The layer unit is configured as a liner, which is placed on one side of the plate unit. The layer unit, which is intended for a decoration, is configured in each non-transparent operating state for visible light and presents colors visible to a user in each operating state.

From the German publication DE 10 2004 033 715 A1, a glass plate or glass-ceramic plate is known, which is typically used in the household appliances sector as cooking surfaces, cooking oven crystals, observation glass fireplace, control screens, etc. The functional decorative layer serves in this case for the representation of screen, design and / or security functions by means of a corresponding functional decoration. The functional decorative layer contains in the zones of the respective functional decorations at least one substance, which in the case of invisible power supply outside, can be activated so that they appear visually optically.

The German publication DE 10 2004 040 759 A1 publishes a ceramic or ceramic hob, which typically finds application in the household appliances sector such as cooking surfaces, cooking oven crystals, chimney observation glasses, control screens, etc. It typically has at least one area for the representation of a function, for example a screen. The ceramic or ceramic hob is provided with at least one substance in the form of luminosforms, which in the case of external power supply of excitation energy, radiates luminescence light in the visible area. A zone of external exciting energy is associated to the zone for the representation of a function, so that the zone can be excited according to the geometry of the function to be represented.

It is already known from the international patent application WO 2008/128900 A2 an home appliance device with a glass of at least partially transparent material, comprising a front side or rear side accessible to a user. A partial area of the glass is provided under the front side or rear side with luminescent material.

The US document US 2004/0112887 A1 publishes a procedure to notify people that the cooking surface of a kitchen is hot. The method comprises that a zone of the cooking surface has an annular element of a thermochromic composition, which surrounds each heating element of the kitchen and represents a heat warning symbol to notify people that the heating element or an area that It is in its proximity is too hot to grab them. A liquid crystal composition or other thermochromic composition, which is intended to have and maintain, at a temperature or above a predetermined temperature, for example 115 degrees Fahrenheit, a noticeable color change, is formed as the outline of the word " HOT "or as another heat warning symbol and is intended to adopt a transparent color and thus under the composition a heat warning symbol configured as such a label or other warning symbol may be visible. The annular element is configured in such a way that it has a ring, a circular arc or a line, which surrounds the heating element, as well as an arrow pointing on the heating element.

In the same way it is conceivable that a single light source is provided, which is intended to activate all the layer units in an operating state by means of infrared radiation. In this case, for example, a beam scattering and / or splitter element could be arranged in the light source to widen a beam of light generated by the light source. In particular, by means of the beam scattering and / or splitter element, in particular by means of the widened beam of light, diffused light can be generated to especially illuminate the base body at least partially, in particular at least for the most part possible, with full advantage. In particular, the base body is divided into several partial zones, so that each light source illuminates one of the partial zones. In particular, the partial areas illuminated by the light sources are made so that they overlap, in particular to achieve high flexibility and / or a high plurality of configuration. The light sources 20, which in each case comprise a laser, are provided to emit infrared radiation in an operating state with an essentially 800 nm wavelength.

In this case, the extractor hood 28 is arranged above the base body 12. Alternatively, the light sources could be arranged in the cover unit. In the same way it is conceivable that the light sources are integrated in the base body. In this case, the light sources may be arranged, for example, between the heating units and / or in the control elements and / or in a center of the base body. In addition, it is conceivable that infrared radiation emitted by infrared sensors of the control elements is used for activation of the layer units. For example, infrared radiation, emitted by a hot cooking dish and / or by the base body, which is heated through the cooking tableware, could be used for the activation of the layer units, if this infrared radiation It has enough energy.

In one configuration of the invention it is conceivable that the layer unit is arranged at least essentially on a complete side, in particular the rear side, of the base body. In particular, the light source could generate by means of a moving light beam, especially laser beam, marks discretionary. For example, by means of the mobile light beam of the light source, an emission of operating parameters, in particular of a heating power and / or a density of heating power, could be generated, in particular to replace an emission unit.
