In such an embodiment, in an assembled state, the latching hooks, in particular the latching lugs, engage in a form-fitting manner around the associated edge sections of the electronic circuit board. In that regard, the electronic circuit board can be snapped onto the light-guiding component.

The household appliance can have a fastening frame and the fastening frame can have second holding means, in particular second holding means comprising second latching hooks, which are designed to fasten the light guide component to the fastening frame.

The fastening frame can have second holding means, which are designed to include the light guide component and thus the assembly of the input device, at least the input means or the flexible carrier, in particular the touch screen, the holding device or the light guide component and the electronic control board on which to attach the mounting frame. For this purpose, each second holding means can be designed as a second latching hook. Each latching hook can be formed in one piece with the fastening frame and can comprise a resilient shaft section and a latching lug arranged at the free end of the resilient shaft section. In such an embodiment, in an assembled state, the second latching hooks, in particular the latching lugs, engage in a form-fitting manner around the associated edge sections of the light-guiding component. In this respect, the light guide component or the entire preassembled input device can be snapped onto the mounting frame and thus also onto the control panel.

The household appliance can have a control panel and the fastening frame can be arranged on a rear side of the control panel, in particular can be designed in one piece with this control panel.

The household appliance can have a glass front pane, in particular a glass door leaf, and the fastening frame can be arranged on a rear side of the glass front pane, in particular on the rear side of the glass door leaf.

For the resilient mounting of the light channels or light shafts on the light guide component, elastic web sections can be provided which elastically connect each individual light channel or light shaft to the light guide component. Each web section can run in an S-shape, connecting the respective light channel or light shaft to the light-guiding component. The web section, the light channels or light shafts and the light guide component can be manufactured as a one-piece plastic injection molded part.

For example, due to a large number of controls and variant-specific requirements, such as a different number of controls, different door concepts - glass and metal door, etc., a flexible solution is provided according to the invention, which can be used both for the controls of metal door variants, as well as glass door variants. In this case, the operating elements are designed in particular as elements of a touch foil. The touch foil is attached to a plastic housing with light wells.

There are generally known touch foils that are glued to the light well.

The invention, on the other hand, describes a non-destructive, detachable attachment and assembly of the touch film on a plastic housing with light shafts, which at the same time Recording for a printed circuit board, ie represents a control board. For attaching the touch sheet to the plastic housing, like a light guide component, the touch sheet has four mounting holes on opposite faces of the touch sheet. One hole on each side can be shaped as an elongated hole in order to compensate for the manufacturing tolerances of the touch foil and the plastic part. With these mounting holes, the touch foil is attached to four mounting hooks. Of these fixing hooks, two hooks are designed as flexible hooks, and the other two hooks are rigid. To attach the touch foil, the touch foil can be hung on the two flexible hooks. The touch foil can then be attached to the two rigid hooks. The flexible design of the hooks makes it possible to mount the touch foil on the two rigid hooks without damaging the touch foil, and on the other hand the touch foil is stretched over the light well and held in position by the flexible hooks.

In the known solutions, the touch foil is glued over the light wells. Therefore, an advantage of the solutions described according to the invention is that no gluing processes are necessary during assembly, which place special demands on the surface quality of the light well. The film can be attached in a manual process without tools. In contrast to a glued touch foil, the touch foil can be attached again if the touch foil becomes detached. If the film was glued, it would have to be removed and would therefore be destroyed. Since the plastic housing has flexible light shafts that ensure the touch foil is pressed against the back of the control panel, for example a glass door leaf, the attachment of the touch foil also supports this solution, as the touch foil is flexible over the entire surface.

The invention according to claim 1 accordingly relates to a household appliance, in particular a refrigeration appliance, a cooker, a hob, an extractor hood, a dishwasher, a washing machine, a tumble dryer or a fully automatic coffee machine, which has an input device according to the invention, as described.
