Description

The invention relates to an electrical appliance, in particular a dishwasher or a refrigerator, which is provided in a kitchen with a flat to be attached to a door of the electrical appliance panel. Likewise, the invention relates to a corresponding arrangement of such an electrical device with a diaphragm and a method for producing such an arrangement.

Such electrical appliances are also known as built-in or fully integrated household appliances. They have no own front or front panel, which should be visible when installed. Rather, a panel is attached to the front of the door, this panel can be kept in an otherwise in the kitchen, the fronts forming design. Typically, such a panel is a panel made of wood or a fiberboard with a coating, such as a paint or a real wood veneer.

From the EP 1576632 A1 as well as the EP 1421893 A1 Such electrical appliances in the form of dishwashers are known, which are designed as fully integrated household appliances. At their doors so an aforementioned aperture is attached. In order to be able to create a visible to an operator display, for example, to be able to display a residual maturity of an operating program, they have the bottom of the door or behind the door on a kind of projection device. This maps a light indicator on a floor in front of the device. However, this has the disadvantage that this area is not always clearly visible, especially from a slightly greater distance. Depending on the nature of the floor, a projection can be very difficult to recognize.

Task and solution

The invention has for its object to provide an electrical appliance mentioned above, a corresponding arrangement of such an electrical appliance with a diaphragm and a method for producing such an arrangement, with which problems of the prior art can be solved and it is in particular possible, a display or to provide a light indicator for such an electrical appliance with a front panel mounted practical and inexpensive.

This object is achieved by an electrical appliance with the features of claim 1, by an arrangement with the features of claim 8 and by a method for producing such an arrangement with the features of claim 13. Advantageous and preferred embodiments of the invention are the subject of the other claims and are explained in more detail below. Some of the features are described only for the electrical appliance, only for the arrangement or only for the process. However, they should be able to apply independently and independently of each other both for the electrical appliance as well as for the arrangement and for the procedure. The wording of the claims is incorporated herein by express reference.

The electrical appliance, which is advantageously a dishwasher or a refrigerator and which is to be installed in a kitchen, has a door for opening, wherein on this door a flat or large-scale aperture is applied, as can be done with integrated electrical appliances. This door can be advantageously covered over the entire surface of the panel. Furthermore, the door can be articulated open particularly advantageous, but alternatively be thought for a so-called pull-out refrigerator.

According to the invention a display device is arranged on the door, which has a light indicator or forms. This display device will be explained in more detail below in its construction, but may be located at the front of the door of the electrical appliance, in the door or even behind the door. Advantageously, it is at least partially or a part of it arranged on the forward or outward facing front of the door. A part of the display device can project beyond the front or front surface of the door, in particular an optical part of the display device or possibly provided light guide body or light guide, as will be explained in more detail below. The survival of the display device or at least a portion of the display device has the meaning that it can thereby extend into a recess to be mounted in the diaphragm for the production of said arrangement recess or recess to be produced closer to the front surface or closer to to provide a covering covering or covering its front surface. Advantageously, it is applied to the back of the lamination. This lamination is designed to be transparent in this area of the display device in such a way that the illuminated display in an activated state, if it shines, illuminates through the lamination and can therefore be recognized by an operator. The closer the display device is to this lamination or a back side of the lamination, the better, brighter and sharper the illuminated display can be perceived.

With the invention, it is possible that a trained as a fully integrated electrical appliance electrical appliance is provided as usual for installation in a kitchen with a said aperture. In this panel, however, just simply arbitrarily arranging any display device results in a usually not particularly advantageous optical impression, which is to be avoided precisely by the provision of such a panel. If the electrical appliance is not in operation, nothing should be visible, in particular no deactivated or inactive display device, which usually does not look very attractive visually. The above-mentioned prior art avoids this yes by the projection down to the floor area, which also is not visible in the non-active state, neither light display nor display device.

In an advantageous embodiment of the invention, the light display can occupy a single closed area on the door. This means that the light indicator is not provided at a plurality of separate or remote locations, so that only a single recess must be made in said aperture. In addition, a spatially combined light display is visually appealing, in addition, the production cost is significantly reduced for the display device.

In a further embodiment of the invention, the display device or the illuminated display can have a plurality of independently illuminable lighting elements. These can, for example, form at least two seven-segment displays and have LEDs for this purpose. Their arrangement or the construction of a light display can be done according to the prior art, as he also for example from the DE 10352714 A is known. Such seven-segment displays can display both numeric values and simple letters or symbols. The lighting elements can also form any other symbols or illuminate and display.

An electronics for the display device, in particular on a printed circuit board or a component carrier may be attached to or on the front of the door of the electrical appliance. It is protected and covered by the front panel to be attached. A connection to this electronics can by means of cable, foil conductor or the like. through the door, as often in such electrical appliances, especially dishwashers, and the control device and the controller sitting in the door. Alternatively, an electronics may also be arranged behind or in the door and only one type of separate display module of the illuminated display with luminous elements and the aforementioned light-guiding bodies or light guides may be arranged on or in front of the door, in particular projecting therefrom. This can be achieved in that the aperture a smaller recess can be provided, since not the entire electronics space must find in it, but only the aforementioned display module or lighting elements and light guide or light guide.

In a further embodiment of the invention it can be provided that the display device has at least one aforementioned translucent Lichtleitkörper or light guide for the light indicator. Such a light guide body or light guide is preferably arranged between the aforementioned luminous elements and a front side surface of the diaphragm. They serve, as known from seven-segment displays, not only to the light pipe, but also by appropriate material compositions to equalize a light phenomenon, thus forming a kind of diffusion body for the light indicator. So it can be used in principle a similar material. This also serves to ensure that the abovementioned luminous elements do not themselves have to be arranged as close as possible to the lamination in order to be easily recognizable through them or to form a good recognizable luminous display. Furthermore, under certain circumstances, they can also be designed so wide or large that they completely fill the recess in the panel, in particular flush with the surface. So the applied lamination is, so to speak, on a flat and continuous surface and in turn gives a smooth and even and thus beautiful surface.

It is possible that an aforementioned optical fiber or optical fiber has a masking masking. Such a masking can be a kind of paint or printing. In this case, at least one cutout per light guide body or light guide is provided, which forms a kind of transilluminable symbol. Thus, in addition to an aforementioned seven-segment display, a symbol in a specific form can also be displayed as a light-emitting display in a light-guide body or light guide of a very simple design.

In an embodiment of the invention, the display device may have a cover or a cover plate. This can form the front of the display device. Such a cover or cover should be at least partially translucent. It serves as a termination of the display device, in particular as a mechanically stable termination and possibly also in order to achieve a stable and flush-mounted closure in the aforementioned recess in the diaphragm. Such a cover or cover may advantageously consist of glass or completely translucent plastic. Possibly, it may also at least partially have the aforementioned properties of light guide body or light guide, ie of translucent or opaque material exist and ensure a homogenization of the indicator. It may also be possible, on the front side and / or the back side, to have the aforementioned masking for displaying a transilluminable symbol.

An aforementioned cover or cover may advantageously be formed in a very simple basic geometric shape in order to facilitate the production of a recess in the panel and the fitting. Here is a rectangular shape or, even better, a circular shape. Thus, in a panel made of wood or fiber material with a circular saw very easily a well-defined and exact recess can be made.

It is possible that an aforementioned display device with electronics or their component carrier or, if this is arranged elsewhere, at least one cable connection, the lighting elements, possibly a light guide or light guide and possibly a cover or cover is designed as a self-contained assembly. This can then be easily attached to the door of the electrical appliance or attached when installing the electrical appliance. Especially with a mobility of the display device in conjunction with a cable, flex conductor or the like. Thus, an exact adaptation to a recess produced in the diaphragm can be achieved in order to be able to compensate for errors or tolerances that arise.

Such movability of the display device with respect to the door or a front side of the door can advantageously be at least in one direction perpendicular to the front of the door, advantageously in general. This makes it easy to adapt to different thicknesses of a panel to be attached. The cables, flex conductors or the like. can compensate for this by appropriate length dimensioning.

In a further embodiment of the invention, it is also conceivable that not only the electronics is arranged behind the front surface of the door of the electrical appliance or in the door, but also the lighting elements themselves. Then advantageously can be arranged on the door display device quasi formed by optical fibers, which depart from said unit and run in the door and emerge at the front of the door. So they can then be connected to the aforementioned further Lichtleitkörper or optical fibers, which in turn then make, so to speak from the luminosity of the optical fiber symbols representing a light indicator.

An arrangement according to the invention thus has a prescribed electrical appliance and a cover therefor, wherein the panel is attached to the door of the electrical appliance. This can advantageously cover the door largely, at an upper edge and on the sides, particularly advantageously at least substantially also downwards. A recess is provided in the bezel when the device is manufactured, in order to arrange the display device therein, or at least the areas that protrude beyond the front of the door. Such a recess may be continuous, advantageously with constant cross-section, in particular in order to make it easier, as has been described above, for example with a circular hole saw. This functionally serves above all to arrange an area or a front side of the display device as close as possible to a front side of the panel or the lamination to be applied. Advantageously, a front side of the display device rests directly on a rear side of the lining. So a fluoroscopy in the activated state of the light display is well possible, while in the deactivated state of the light display only the lamination is seen with their optics. This lamination covers the aperture at least in the region of the display device, so that it is not visible, in particular not in its function as a display device. A lamination as above-described film or a foil-like lamination may have a thickness of less than or equal to 1 mm, preferably 0.01 mm to 0.5 mm thick. In any case, a transparency of the lamination should be such that it can be transilluminated by the illuminated display or the light of the lighting elements of the display device, and thus the illuminated display can be recognized. In addition to a thickness of the lamination or their material and production, the smallest possible distance between the front side of the display device or light exit from the display device and the lamination itself or its rear side must be taken into account.

On the one hand, said lamination can have a plastic carrier film on which a decorative layer is applied, which forms the front or front surface. Such a decorative layer may be a color layer or else a thin metallization, as is known from the field of film technology, however. If such a metallization is thin enough, it can also be well illuminated by a light display, which has, for example, as a light-emitting element a conventional SMD LED with medium brightness.

In yet another advantageous embodiment of the invention, the display device at a front or front at least one touch switch or a proximity switch for operating functions of the electrical appliance. So it can be created a kind of control device with control and light indicator. This is particularly advantageous a touch switch or proximity switch with a capacitive sensor element, but also optical touch switch or proximity switches are possible with transillumination of the yes translucent lamination. Likewise, other functional principles of touch switches or proximity switches are conceivable.

The touch switch or proximity switch is located near the indicator or within the indicator, so within their luminous appearance. Preferably, the display device, the one or more touch switches or proximity switches and capacitive sensor elements provided for this purpose can be designed as a structural unit. So installation and especially electrical connection are easy to perform. The aforementioned component carriers or printed circuit boards for the illuminated display or its electronics can also carry the touch switch or proximity switch with the sensor elements. Particularly advantageously display device and touch switch can be integrated or designed as a structural unit according to the prior art, see for example the DE 10352714 A1 for an optical touch switch or the EP 1030536 A2 or the WO 2011/012501 A1 for a capacitive touch switch. There are examples of the design or integration of display with lighting elements, light guide and capacitive sensor elements as a touch switch included. The units shown there can also be used here in principle in the present invention with advantage to realize the functions of light indicator and control function in a novel phenomenon, namely behind a lamination on the front of the door of an electrical appliance.

In an extension of the invention can be provided that optical or capacitive sensor elements serve simultaneously as a touch switch and as a proximity switch with respect to the front or the surface of the lamination. So you can first recognize an approach of a finger and that a touch with your finger and distinguish each from each other. Thus, it is possible that when approaching with his finger on the lamination in the region of the display device or operating device, for example, less than 10 cm or 5 cm, in the function as a proximity switch, the light indicator is activated. Thus, an operator can be displayed the possible functions as a control device by the light indicator. In the function as a touch switch can then be made a specific operation. For the exact realization is on the DE 102007057076 A1 directed. Although this is related to always visible mechanical rotary knob, this also reveals this for both optical and capacitive sensors. It will then be easy for those skilled in the art to use these sensors for operation, and the transfer to the present application will also be readily apparent to those skilled in the art with this advice.

A touch switch or capacitive sensor elements should advantageously bear against the back of the lamination for a good function or reliable detection of an operation or touch or approach. Thus, a flush design of the front of the door is achieved or maintained. In order to allow a transillumination or not to affect the light display, the sensor element can either surround a light element, as it DE 10352714 A1 or the EP 1030536 A2 demonstrate. Alternatively, a sensor element may be translucent, as it is the WO 2011/012501 A1 shows, and extend over a large area above or above the lighting elements. An electrical contact to capacitive sensor elements on top of a display device or a light guide can be done as described there, advantageously on laterally extending contacts.

For the inventive method applies that in the panel for mounting the electrical appliance in the kitchen a recess must be made, which is at least so large that it can accommodate the display device. In particular, it must be able to accommodate the front of the door part of the display device. Thereafter, the panel is attached to the door, wherein depending on the nature of the connection of the protruding part of the display device with the electrical appliance or the door an adjustment of this projecting part in the recess takes place. A mounted on the front of the panel or arranged lining then ultimately covers the display device.

There are two possibilities for the chronological order of the attachment of the lining to the panel. On the one hand, the lamination can be attached to the panel before the panel is attached to the door of the electrical appliance. Although the application of the lamination may be simplified, the arrangement of the panel on the door is somewhat more difficult. Furthermore, care must be taken during this assembly process not to damage or negatively affect the lamination. On the other hand, the lamination can be attached to the panel after the panel has already been attached to the door. This is a bit more involved. But then attaching the lamination is the last assembly step and this can be better protected against damage. Furthermore, the arrangement of the display device in the recess and a possible adjustment or accurate adjustment are easier.

These and other features will become apparent from the claims but also from the description and drawings, wherein the individual features each alone or more in the form of sub-combinations in an embodiment of the invention and in other fields be realized and advantageous and protectable Representations for which protection is claimed here. The subdivision of the application in individual sections as well as intermediate headings do not limit the statements made thereunder in their generality.

Detailed description of the embodiments

In the Fig. 1 a kitchen 1 is shown with a simplified front view of a kitchen front, which is designed as usual. Under a worktop 2, a base 4 and right next to drawers 5 are arranged. To the left of the lower cabinet 4, an inventive arrangement 10 of a dishwasher 11 is provided as a household appliance according to the invention, which is designed and arranged as a fully integrated household appliance. The sectional view of the Fig. 2 serves in conjunction with the documents of the prior art explained in the introduction to better understand the arrangement 10 of the dishwasher 11.

The dishwasher 11 has a door 13 which is hinged at a lower edge, as is customary for such fully integrated dishwashers. At an upper edge of the door 13, not shown here, an operating device is arranged with controls in the form of push buttons or touch sensors. An essential part of the control of the dishwasher 11 is thus contained in the door 13.

The front or front surface of the dishwasher 11 in the Fig. 1 is formed by a film 40 as a lining according to the invention, which covers the entire front of the door 13. A recognizable handle 16 of the dishwasher is placed on top of this film 40 and fixed, for example, screwed. In the upper part of a light indicator 18 can be seen, here from a kind of seven-segment display of a Fig. 2 is formed to be seen display device. It represents the number "87", which is clearly visible as a light indicator 18. This number indicates to an operator the remaining time of a currently running program of the operation of the dishwasher 11. Basically, however, very different symbols or information can be displayed. In this case, the light indicator 18 and the film 40 are formed so that in the deactivated state of the light indicator 18, so if it is off, nothing can be seen. An operator then only perceives the front side of the film 40 or the film 40 itself. At the same time, the film 40, at least in the region of the illuminated display 18, but so translucent, usually by a correspondingly small thickness, that when activated, so luminous, light indicator 18, a transillumination of the film 40 is possible. The indicator 18 is then easy to see.

The structure of the embodiment of Fig. 2 shows the door 13a in section, wherein in the door 13a to the right to the front of the dishwasher 11 toward or to the arrangement 10a toward a recess 14a is provided. This may be a few millimeters deep and have a diameter or width and height of a few centimeters, for example 3 cm to 10 cm. A channel 15 leads from the depression 14a to a control of the dishwasher 11 arranged in the door 13a. A feed line 20a extends there as electrical supply and control to a component carrier 19a, which is completely embedded in the depression 14a.

The component carrier 19a is part of a display device 17a and may possibly have further components on one of its upper sides. These can be used to control one of the LEDs 22a on its right-facing front. These LEDs 22a are advantageously SMD LEDs, wherein they should be designed relatively bright with a light output of at least 0.01 Im, preferably at least 0.1 Im. In order to operate the light indicator 18 as intended, any number of LED 22a in any arrangement be provided. At least two seven-segment displays are advantageous accordingly Fig. 1 can be displayed, under certain circumstances also another, in order to be able to display a symbol or a letter in addition to a two-digit number.

On the component carrier 19 or via the LED 22a, a light guide 24a is placed, which is advantageously formed in one piece and block-like. It may serve to even out the illumination of the LED 22a for a uniform and beautiful-looking light indicator 18a. Furthermore, it can serve as protection and front cover of the display device 17a. For this purpose, it can be accurately inserted into a recess 32a in a diaphragm 30a. Such a diaphragm 30a corresponds to a conventional diaphragm, as it is used for a fully integrated dishwasher 11 in an arrangement 10 according to the invention. Advantageously, such a panel 30a made of wood or plywood or fiber material such as pressboard or MDF. While the panels for attractive fronts of the cabinet 4 and the drawers 5 are painted in front or can carry a real wood veneer, this is not absolutely necessary for the panel 30a. However, all fronts of the kitchen can be covered with the same foil, for example as a kind of renovation. The recess 32a is made to fit the light guide body 24a and the display 17a therein, usually by a kitchen maker or technician of the kitchen. It is also installed in exactly to the dishwasher 11 matching position.

At the front of the panel 30a, a film 40a is applied as a lamination, in particular glued as a self-adhesive film. This film 40a covers, like the Fig. 1 shows the entire door 13 of the dishwasher. Only a recessed lower bar is usually not covered, as is known from such fully integrated kitchen appliances.

The film 40a is generally advantageously made of plastic or has a plastic base as a kind of carrier. It may have a colored coating on its front or be dyed through. Likewise, it may represent a wood veneer imitation, possibly even with a light structure, as is known for such wood veneer films. Likewise, it may have a thin metallization. In any case, however, it should be translucent such that the light of an aforementioned LED 22a is visible therethrough. Apply this film 40a then the same fitter for the kitchen.

In the dishwasher 11a and the door 13a accordingly Fig. 2 the display device 17a, in particular with the component carrier 19a, fixedly secured in the recess 14a of the door 13a, for example, glued. The light-guiding body 24a projects beyond a front surface of the door 13a, but disappears, as it were, in the recess 32a of the panel 30a. The display device 17a is mounted on the door 13a at the manufacturer or at the factory of the dishwasher 11a.

Important in the arrangement 10a accordingly Fig. 2 , and actually also generally, it is that as far as possible no gaps or air spaces between LED 22a and / or light guide body 24a and foil 40a exist. These would severely adversely affect both the luminosity and the sharpness of the optical representation. While the LED 22a may still have a small air space to the light guide body 24a, the film 40a should rest directly on the front side of the light guide body 24a.

A symbol shape or defined luminous shape of the illuminated display 18a can be formed by corresponding channels in the optical waveguide 24a, which are not shown here, but are known from the seven-segment displays mentioned above. Alternatively or additionally, an additional masking or printing with corresponding cutouts can also be provided on a front side of the light guide body 24a.

The film 40a should therefore also be glued to the front of the light guide 24a. In addition to the above-mentioned technical reasons for better fluoroscopy, this is also important for the most pleasing visual appearance. Furthermore, the light guide body 24a should be arranged as accurately as possible in the recess 32a, so that no joints through the film 40a can be seen or when loading the front of the dishwasher 11, for example, during cleaning, no such gap or depression is visible. Finally, the purpose of the film 40a as lamination is to give the impression that a stable, continuous and uniform or monolithic front is present.

In a modification of the embodiment of the invention accordingly Fig. 3 is in an inventive arrangement 10b in a door 13b of a differently designed dishwasher 11b only a continuous channel 15b provided. On the back of the door 13b, ie inside, a component carrier 19b is arranged. It may be covered towards the inside of the dishwasher 11 b and, in particular, connected to a control of the dishwasher, not shown here. It is easy to imagine that the component carrier 19b here completely eliminated and its functionality of driving LED 22b of the display device 17b or for the light indicator 18b of components or a processor of the general control of the dishwasher is taken.

In the channel 15b in the door 13b, a supply line 20b extends to the LED 22b, so that they are formed as a kind of integrated assembly together with the light guide body 24b and an electrical connection, not shown. This light guide 24b or this Assembly is in turn arranged in a recess 32b of a diaphragm 30b, which accordingly Fig. 2 can be trained. This arrangement should therefore again be made accurately and flush with the surface. From the front, a film 40b is applied as a lamination according to the invention, which covers the entire front side of the panel 30b and thus also of the door 13b and forms the optical surface. To form this film 40b the same applies as previously stated. A light indicator 18b can be seen when the LED 22b is activated. If the LEDs 22b are inactive, nothing is discernible except the front of the film 40b.

A further alternative embodiment of an arrangement 10c according to the invention is shown in FIG Fig. 4 shown. In a door 13c of a dishwasher according to the invention, a relatively large channel 15c is provided. It leads upwards to a control of the dishwasher, not shown, and contains two light guides 26c or actually much more, namely per luminous segment of the light indicator 18c, a light guide 26c. The light guides 26c lead with slightly enlarged ends into a light guide 24c, which consists of a previously described plastic. It also belongs to the display device 17c and is correspondingly flush tight and firmly inserted into a recess 32c of a diaphragm 30c. On the front side could now according to the representations of FIGS. 2 and 3 again be directly glued to a corresponding foil as a lamination. Here, as a modification, a full-surface pane 35c is provided with light-permeable material at least in the region of the illuminated display 18c. This disc 35c covers the entire front of the door 13c and the panel 30c. So it is also attached by a fitter of the kitchen, possibly even tailored. Therefore, as a material for the disc 35c, a plastic, for example, acrylic. Its strength can be relatively low, for example 1 mm to 5 mm. The task of this disc 35c is an additional protection for the display device 17c. Furthermore, what has been explained above, an exactly full-surface and uninterrupted flat front side should be provided, which can then be provided with the film 40c as a lamination or glued. However, such a large or full-surface disc 35c may be provided regardless of whether LED as in the FIGS. 2 and 3 are provided on the front of the display or a few millimeters below the film 40 or whether, as here in Fig. 4 the case, light guides are provided.

The light guides 26c may have a certain freedom of movement for the light guide body 24c, so that it can be inserted well into a recess 32c in the aperture 30c and certain installation tolerances can be compensated. An intervening gap would not be so bad in the present case, since the full-surface disc 35c is still mounted in front of it.

In the Fig. 5 In a further embodiment of an arrangement 10d according to the invention with a door 13d of a dishwasher, an electrical supply line 20d is again provided in a channel 15d of the door 13d. In a recess 14d at the front of the door 13d a display device 17d according to the invention is arranged. However, a component carrier 19d of the display device 17d is not fixedly or flush inserted into the recess 14d, but has a distance therefrom. The component carrier 19d is held in that it forms a structural unit with the optical waveguide 24d or adheres to it or is otherwise mechanically connected thereto. The light-guiding body 24d, in turn, is connected with its front side to a pane 35d and, at the same time, to its rear side, so that as a whole a structural unit is formed. This disc 35d is fixedly arranged in a recess 32d in the diaphragm 30d, for example glued. This is done without joint and flush with the panel 30d, so that again very easily a film 40d can be glued as a lamination.

However, a capacitive sensor element 28d is still attached here on the front side of the light guide body 24d, as explained above as an advantageous possibility. The capacitive sensor element 28d here is advantageously flat or particularly advantageously arranged over its entire surface on the front side of the optical waveguide 24d, preferably in accordance with the aforementioned WO 2011/012501 A1 as a coating. Thus, a large sensor element is provided. It is electrically contacted and connected to the component carrier 19d by a laterally guided on the light guide 24d along electrically conductive connection, for example, by a lateral coating, in particular to a control and evaluation, as is known from the cited prior art and here easy to realize. Therefore, a more detailed presentation can be omitted. By placing a finger on the lining 40d in front of the capacitive sensor element 28d through this and through the disc 35d therethrough in the usual manner an operation. The lamination should therefore be designed so that this is possible. The position of the capacitive sensor element 28d or a contact switch formed thereby can be mediated by the illuminated display. Likewise, it can thus also the above-described function of a proximity switch can be realized, namely it can detect whether a finger, for example, approaches less than 10 cm or 5 cm. Then can be activated via a corresponding control only the light indicator 18d, which was previously completely or partially disabled.

The display device 17d is here by the capacitive sensor element 28d to an operating device with light indicator and at least one control element for an operator, so with input and output. For example, a dishwasher could as an electrical appliance by placing the finger on a flashing light indicator 18 d, indicating the end of a rinse, be turned off without having to open the door 13.

In this embodiment, therefore, a disc 35d is also provided for the display device 17d, but corresponding to the light guide 24 in the embodiments of the FIGS. 2 and 3 flush with the surface is inserted in the aperture 30. However, the disc 35d can be quite thick and mechanically stable. Furthermore, it has the advantage that a certain flexibility in the arrangement or placement is possible by the formation of a structural unit together with the light guide 24d and the component carrier 19d, since no attachment in the door 13d is provided directly and the aforementioned recess 14d also allows sufficient margin.

Out Fig. 5 It can also be seen that the usual LED 22d is again provided on a front side of the component carrier 19d, but also other electrical components on the rear side, for example for driving this LED 22d and / or the capacitive sensor element 28d. Due to the slightly larger recess 14d sufficient space is given here. By gluing the disc 35d in the recess 32d, a mechanically stable arrangement can be created, which does not have to be supported inwardly. A disk 35d may also be made of plastic, for example of acrylic glass, and have a thickness of 2 mm to 5 mm or even more. So it is stable enough not to be depressed in the area of the display device 17d.

It is easy to imagine that instead of a dishwasher 11, another electrical appliance can be installed in this way, and not only mandatory in a kitchen with continuous fronts. In general, such an electrical device can be created with an individualizable front or optics. At the same time just a light indicator on this electrical appliance should be possible, which has the great visual and technical appeal that it is not visible in the disabled state and just visible as a light indicator when it is active. Under certain circumstances, even an operating device with light indicator and touch switches or proximity switches can be created as controls.
