Description

  • The invention relates to an electrical household appliance, in particular a washing machine, a tumble dryer or a dishwasher, with at least one operating device, which is associated with at least one display device for optical operator information.
  • The housing of washing machines, dryers, dishwashers or other household electrical appliances of comparable size are usually constructed in several parts and have screens on which controls and display devices are arranged for optical operator information. These panels are nowadays mainly made of high-strength, impact-resistant plastic by injection molding. The controls in the form of knobs, switches, buttons, touch pads or the like allow the user manual operation of the device. Display devices are provided for displaying the device status and / or for displaying values, for example temperature values or the like. Multi-segment displays, such as LCD displays, are often used to display values. To display states, LED displays are usually used, which are usually switched so that they light up when a corresponding state is active. For mounting the LCD displays or the light-emitting diodes, through-openings adapted to the shape are either already formed during spraying or introduced by subsequent mechanical processing.
  • Especially for applications in wet rooms, such as washing machines or dryers, it is appropriate to the area seal the display devices used, so that no moisture passes through the aperture in the usually arranged behind the panel electronic control device of the device. The bezels also offer little flexibility in the variant formation, since for each equipment variant of an electrical household appliance, which is characterized by a certain number and certain types of display devices, specially adapted panels must be kept with a corresponding number of openings. The lack of flexibility in variant formation has a detrimental effect on achievable delivery times and the cost of finished devices.
  • The WO 98/31864 shows a panel for household appliances with various design options. In order to illuminate operating symbols or backlighting openings are provided in the aperture. A second outer layer of the panel of transparent material covers these recesses and closes them. Light can radiate through the transparent properties of the second layer of material.
  • Task and solution
  • The invention has for its object to provide an electrical household appliance of the type mentioned above, for the production of a high flexibility in the variant formation is given and which is characterized by reliability and attractive design.
  • To achieve this object, the invention provides an electric household appliance with the features of claim 1. Further, an operating device or a panel for such household electrical appliance with the features of claim 28 is provided. Advantageous developments of the invention are specified in the further claims and are explained in more detail below. The wording of all claims is incorporated by express reference into the content of the description.
  • In an inventive electrical household appliance of the type mentioned above, the operating device consists at least partially of a covering material which is substantially opaque in the selected for the surface of the operating device standard material thickness. In an area provided for the display device, the operating device has at least one transillumination area, in which the material thickness of the covering material is reduced in relation to the standard material thickness in such a way that the transillumination area can be transilluminated at least in regions by the light of a light source assigned to the operating device. When the light source is not activated, the transillumination area should be opaque.
  • As a control device can serve a variety of facilities. This will be discussed in more detail.
  • Control devices according to the invention therefore do not have to have through holes for the introduction of light sources, displays or the like in the region of the display device. Rather, it is according to the invention with a suitable choice of material for the operating device possible to make them translucent in the transillumination area and otherwise in the environment of the transillumination area and all not required for a visual display functions areas with such a large wall thickness that the control device as a dimensionally stable component a protective function can take over for the arranged behind the control device components.
  • It may be provided that the light source is arranged opposite the transillumination region on the rear side of the operating device.
  • In particular, any suitable plastic can be selected as cover material, for example a suitable ABS plastic, as used, for example, in conventional covers for household appliances or in housings for other electrical appliances. In the case of plastic diaphragms, it is possible to introduce the transillumination region into the component already during the production process by appropriate shaping of the injection tool, so that no mechanical post-processing is necessary. However, it is also possible in a conventionally produced Operating device subsequent fluoroscopy, for example, by material-removing machining to bring.
  • Normally, the standard material thickness is in the range above 1 mm, in particular at least 2 mm. These material thicknesses are sufficient to ensure sufficient stability even with extensively extended operating devices or, for example, diaphragms. In the fluoroscopy area, however, the material thickness should at least partially be less than 0.8 mm. In particular, it should be between about 0.3 mm and about 0.5 mm. It has been shown that, for example, in ABS plastics material thicknesses of about 0.3 to 0.4 mm for light commercial, equipped with normal brightness light sources, such as LED displays, is sufficiently transparent to clear even in bright rooms To distinguish between turned on and off the light source.
  • The invention makes it possible to provide operating devices whose front surface facing the operator is closed in the region of the display device, ie is continuous or continuous. In contrast to conventional control devices so no openings, cracks or the like are present, could penetrate through the example of moisture and / or impurities. Normally the front surface is smooth and easy to clean throughout. In many embodiments, it is such that at the front of the aperture in the vicinity of the transillumination area and / or in the transillumination area, a, preferably permanent, label is attached, which recognizes, for example by means of a suitable icon the function to which the corresponding light source is assigned. It may be, for example, printed or laser-processed symbols, numbers, letters and / or the like.
  • The effect achieved by the invention, namely to create partially transparent or partially transparent areas in an outwardly closed operating device with a continuous, gap-free surface, would also be achievable if provided in the production of an operating device in the field of a display device small "window" made of a plastic would be much more transparent to the light from the light source than the plastic used for the remaining parts of the diaphragm. However, the use of a single covering material for thick and thin areas is much less expensive.
  • The invention makes it possible to use the same operating device with a fixed number of fluoroscopy areas for all devices of a device series, which can be characterized by a large number of different equipment variants. This number of fluoroscopic areas should correspond to the maximum possible number of states and / or display devices to be displayed. If one or the other function is not provided with simpler equipment variants, the corresponding transillumination area need not be used. He is then not visible in the outer appearance of the aperture, since without backlighting the fluoroscopic areas are usually indistinguishable from the surrounding opaque areas.
  • In simple variants, the transillumination region can essentially be characterized by a recess introduced from the rear side into the covering material, in the region of which the material thickness is brought to a transilluminable thickness. In some embodiments, it is provided to provide the light source facing or zuwendbare back of the operating device in the transillumination area with a macroscopic surface structuring. It may, for example, be a scattering structure that leads to a uniform illumination of a broader range of transillumination contributes, even if only a single, small-area light source is used if necessary.
  • A macroscopic surface structuring may have a number of grooves and raised portions, which are then to be dimensioned so that the cover material is so thin at least in partial areas of the grooves that it is transilluminable. For a surface structure having grooves or furrows corresponding to areas of lesser thickness, and thicker lands or raised portions, the raised portions may pass from one to the other of the fluoroscopic area. In this way they contribute to a mechanical stabilization of the transillumination area. In this case, the macroscopic surface structuring can fulfill a dual function. The cross-sectional shape of the grooves may be, for example, V-shaped, U-shaped, trapezoidal or rectangular. The shape of the grooves may be rectilinear or curved. For example, structures with parallel grooves in one direction or with crossed grooves, for example in two mutually perpendicular directions, are possible. In this case, for example, in the case of V-shaped or trapezoidal grooves, the raised portions located therebetween may be pyramidal and optionally form a light scattering structure. Structures with concentric circles are also conceivable. In all structures, uniform or uneven distances between individual grooves or the like are possible.
  • In or on the transillumination area, additional light-modifying or light-conducting devices can be arranged. These can consist of separate parts. It is possible to colorize or colorize the facilities. Also suitable are so-called color slices or color filters.
  • Advantageously, at least one light-modifying or light-conducting device is provided from the following group:
    • Light guides, light distributors, light deflectors, concentrators, lenses, prisms. Of course, a plurality of functionalities can also be configured in one device. In the case of light-conducting elements, the light source can also be arranged further away from the transillumination area.
  • On the one hand, the light-altering or light-guiding device can be permanently and non-detachably connected to the operating device near or directly at the transillumination area. Here either gluing on or an encapsulation or injection offers. Injection is advantageous in a multi-component process.
  • On the other hand, the light-altering or light-conducting device can be releasably attached to the operating device. Here, for example, screw or Klips- or latching connections are preferably used.
  • It is also possible to provide at least one recess in the form of a multi-segment display in the transillumination area, for example in the form of a seven-segment display. Each of the segments can be assigned at least one separately controllable light source to bring the corresponding furrow targeted to appear. On the back of the operating device may optionally be formed on the operating device between the individual grooves corresponding to the segments Abschattungsstege or the like, to prevent over-irradiation of light sources in unassigned segment sections.
  • Display devices according to the invention can be provided largely separately or in spatial association with other operating elements, such as mechanical buttons, knobs, sliders or the like be. In preferred embodiments, an integration of a display device with an associated control element is provided. As a result, a combined display and control element can be created. In particular, the transillumination area can be assigned a sensor device for generating a switching signal which comprises at least one sensor element which responds when approaching a finger or the like and / or when touching a fingertip or the like in order to initiate the generation of a switching signal (proximity or touch sensor). , The control element can be designed, for example, as a capacitive control panel in a sandwich construction, as is the case in German utility models DE 201 19 700.6 is disclosed. The relevant disclosure of this application is made by express reference to the content of the present application.
  • As mentioned above, such an operating device may for example be a diaphragm, but also a movable operating device in the form of a rotary or sliding fog or a button. A movable operating device may be attached to a panel or a side, advantageously the front, of the household electrical appliance. On the one hand, a light source can at least partially protrude into this movable operating device, preferably be arranged therein. On the other hand, the light source in the household electrical appliance can be arranged outside the operating device. For example, a light-conducting channel lead from the light source to the transillumination area, wherein in particular the light-conducting channel is a light guide.
  • The invention also relates to an operating device or a diaphragm of the type described with at least one transillumination region. Such controls or panels provide maximum flexibility in the appearance and color of the device operating front, which is formed or embossed by the operator facing the front surface of the panel. Inventive panels are easy to produce and mountable. They make it possible in a simple manner to introduce light-conducting and / or illumination-shaping devices into the plastic injection material, for example scattering structures or the like. The reliability of the electrical devices equipped with the invention panels increases, since penetration of moisture and impurities in the aperture is reliably avoided.
  • The foregoing and other features will become apparent from the claims, as well as from the description of the 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 Can represent versions.

    Detailed description of the embodiments
  • The schematic representation in Fig. 1 shows a section through the front panel of a clothes dryer in the region of a user-facing panel 10. The panel 10 is a one-piece plastic injection molded component, which is made in the example of ABS plastic. The dimensionally stable component has a front side 11 facing the user with a smooth, shiny, closed surface 12. At most points of the diaphragm, the standard material thickness of this diaphragm 10, ie the distance between the front surface 12 and the rear surface 13, is approximately 2.6 mm. With this material thickness, the visor material ABS is impermeable to visible light, so that the components of the device lying behind the diaphragm, in particular the components of an electronic control, are not visible from the front side. In this material thickness, the diaphragm material is torsionally rigid, so that the entire panel is self-supporting as a separate component and can be easily mounted on this example, by screws during assembly of the device.
  • The aperture is associated with a display device 15 for optical operator information. This display device comprises a light-emitting diode designed as a light source 16, which is mounted on a circuit board 17 which is connected by not shown fastening elements with the diaphragm. In the area provided for the display device, the diaphragm 10 has a circular transillumination region 20, in which the material thickness of the diaphragm material is reduced compared to the standard material thickness 14 such that the transillumination region is at least partially separated from the light of the light source 16 arranged opposite the rear side 13 of the diaphragm its surface is durchleuchtbar. The transillumination region 20 is essentially formed by a region of reduced material thickness in the diaphragm 10. He is surrounded by a circumferential, the light source 16 projecting web 18.
  • In the embodiment, an approximately circular recess was formed in the manufacture of the diaphragm 10 by injection molding by appropriate shaping of the tool, on whose front side 11 facing bottom macroscopic surface structure in the form of furrows 21 and intermediate raised portions 22 is formed. The furrows and raised sections each have a triangular cross-section. In the region of the vertices of the raised portions 22 facing the light source, the material thickness is approximately 0.5 mm, while in the region of the bottoms of the grooves 21 facing the surface 12 it is only approximately 0.3 mm. These material thicknesses are matched to the optical properties of the ABS plastic used so that the light of the light emitting diode 16 in the region of the raised portions 22 weak and in the region of the furrows 21 and clearly visible from the outside, the aperture material in the transillumination area 20, so that for an operator can be seen from the front 11 through the aperture, whether the LED 16 is turned on or off. Thus, the transillumination region 20 of reduced material thickness has the function of a frosted glass window formed integrally with the surrounding diaphragm material The light source 16 facing, structured surface generates a certain scattering effect to allow regardless of the shape of the light source 16, a relatively uniform illumination of the entire transillumination area 20. Optionally, a visually attractive stripe structure within the illuminated area can be seen.
  • The light-emitting diode 16 serves as an optical status indicator for a function of the tumble dryer. For example, the clothes dryer may be configured to illuminate the light emitting diode 16 when a crease protection function or a dry cycle is engaged. An identical or analogously constructed display can also be provided, for example, for the start / stop function. Other modes may also be displayed in the manner shown. In order to allow a clear assignment for the operator between the illumination of a transillumination area 20 and an associated function of the device, a marking 25 is applied by printing on the front surface 12 of the diaphragm 10. This comprises a closed ring 26, which encloses the transillumination area, and a symbol 27 characterizing the corresponding function within the ring 26.
  • The embodiment shown of an electrical household appliance is characterized by highest ease of use, which is supported by the fact that in this embodiment, the display device is combined with a capacitive actuator in sandwich construction. The function indicated by the tag 25 can be turned on or off by the operator by operating a capacitive sensor device. The sensor device comprises a sensor element 30 applied to the rear side 13 of the diaphragm 10, which annularly surrounds the transillumination region 20 outside of the web 18, and a controller 31 on the printed circuit board 17. A possible construction of such a sensor element and its function will be exemplary in the EP 859 468 whose contents are to this extent made by reference to the content of the present application. A corresponding description is also in the DE 201 19 700.6 the Applicant, the content of which is also incorporated herein by reference. Typically, the size of such a sensor element is in the range of the size of a fingertip, for example, may have a side edge length or a diameter between about 10 mm and about 25 mm.
  • An elongated, pin-like contact part 32 extends from the printed circuit board 17 with the controller 31, to which it is electrically conductively connected via a flat contact, up to a contact field of the sensor element 30. In this way, the sensor element 30 is electrically conductive with the control 31 or the circuit board 17 is connected. The contact part can be designed to be elastic, for example as a metallic coil spring or as a compressible element of conductive, elastic plastic.
  • The sensor element 30 is applied directly to the rear side 13 of the diaphragm 10 by means of a printing process, for example a suitable screen printing process. As an alternative to using a screen printing process with an electrically conductive mass for the sensor element 30, a metal foil-like part or plate may also be attached to the rear side 13 of the screen by gluing or otherwise. Metallized or metallic adhesive films can also be used as sensor elements 30.
  • Now, when an operator puts his finger in the vicinity or on the area indicated by the number plate 25, a capacitance change occurs in an electrical circuit comprising the sensor element, which is further processed by the controller 31 to generate a switching signal. At the same time as switching on or turning off the corresponding function, the light emitting diode 16 is turned on or off.
  • Based on Fig. 2 and 3 alternative forms and structures of fluoroscopy areas are presented. Fig. 2 (a) shows a circular transillumination region 35, in which the region of low material thickness on the side facing the light source has a pyramidal structure with a plurality of directly adjacent quadrilateral pyramids 36. If the light source side of the transillumination region is produced by removal of material, then the pyramidal structure can be produced by creating grooves with a V-shaped cross-section directly next to one another in mutually perpendicular directions 37, 38. If the structure is produced during injection molding, then for this purpose the corresponding part of the tool can have a circular area with a corresponding waffle structure. The pyramidal structure has a scattering effect, so that the transillumination area appears to be largely uniformly illuminated from the operator side, regardless of the shape of the light source.
  • In the Fig. 2 (b) Panel 40 shown in section has a rectangular transillumination area 41 which is formed by mutually parallel V-shaped grooves and raised portions. In this case, the material thickness of the panel material in the area of the furrow bottoms facing the front surface 42 is about 0.3 to 0.4 mm so thin that sufficient transparency is present here. In the area of the tips of the raised portions on the back 43, the material is largely opaque at about 0.5 to 0.7 mm thickness. In this way, the transillumination area 41 appears in a striped pattern when the light source is switched on.
  • Based Fig. 2 (c) For example, a diaphragm is shown which has a circular transillumination region 46, in which macroscopic Surface structures are arranged in the form of concentric circles, which may be formed for example by rectangular or V-grooves.
  • The examples of transillumination regions shown so far are preferably usable in conjunction with simple light sources in order to indicate the switching state of a function (on or off). For many devices, it is also desirable to have values associated with a mode of operation or an additional function, such as e.g. Preselection times, remaining maturities, moisture levels, temperatures or the like display. Conventional devices often use multi-segment displays such as LCD or LED seven-segment displays. A corresponding functionality can also be provided using the invention.
  • This shows Fig. 3 schematically a diaphragm 50, which has a thickness of about 2.6 mm in their thickest, illustrated areas. In a rectangular area 51 provided for a display device, the material thickness is reduced to approximately 1 mm. Within this range, a further wall thickness reduction occurs to provide a transillumination area 60 in the form of a seven segment display. For this purpose, 53 furrows 54 to 57 are introduced with trapezoidal cross-section at the bottom of the rectangular area, ie on the opposite side of the front side 52. The grooves form an overall configuration in the shape of a rectangular figure eight and can be thought of as a seven-segment display divided into seven functionally separate partial grooves or furrow segments. Each of the groove segments is assigned a group of light sources. By way of example, a row of three light-emitting diodes 58 is shown, which are arranged at a small distance behind the rear side 53 in the region of the above-visible transverse groove 55. If these light sources 58 light up, then the emerging light falls essentially only in the transverse groove 55, which then lights up noticeably on the front side 52 for the operator. To prevent the light from shining into other segments, you can be shielded by suitable, not shown shields against the light of the light sources 58. Likewise, for example, for the middle transverse groove 57, a row (not shown) of three light-emitting diodes is provided. At the vertically extending longitudinal grooves 54, 56, which are to be divided into two partial grooves, respectively, two independently controllable groups of three light-emitting diodes are arranged, which illuminate these partial grooves.
  • By suitable control of the furrow segments associated lighting sources, any digit and any letter can be symbolized with this display in the manner of a seven-segment display. Normally, a display device has a plurality of such seven-segment transillumination areas arranged side by side, for example, four such areas to indicate times or time intervals, optionally also for displaying temperatures or the like.
  • The Fig. 4 shows a greatly simplified illustrated modification of the aperture 10, which in Fig. 1 is shown. In the Fig. 4 illustrated aperture 60 has a smooth front 61. Of course, here, as appropriate Fig. 1 , Symbols or the like. The aperture 60 has a per se normal material thickness 14, for example, according to the in Fig. 1 , On the other hand, the transillumination area 63 is again made thinner, roughly corresponding to FIG Fig. 1 , However, he has no structure.
  • For a so-called light distribution plate 65 is provided. This is how in Fig. 4 can be clearly seen embedded in the material of the aperture 60.
  • The embedding of the light distribution plate 65 in the aperture 60 can in principle, as previously described, take place in various ways. In Fig. 4 is it injected, in a so-called Two-component process. This is known per se and therefore need not be explained in detail here. In this way, the light distribution plate 65, which may be made of transparent plastic such as acrylic, fixed and insoluble and immovable embedded.
  • Instead of injecting, a light distribution plate 65 could also be clipped. This would be possible if the Hintergreifung in Fig. 4 would be lower. A clipping is indeed less expensive from the production cost of the aperture itself. However, an assembly process is needed.
  • Behind the light distribution plate 65, a first light guide 67 is arranged. Light from a light emitting diode 66 is coupled via a second light guide 68 and the first light guide 67 in the light distribution plate 65. This in itself can be explained by the person skilled in the art from the drawing in connection with the above description and need not be explained in more detail here.
  • As in Fig. 4 indicated, the first and second optical fibers 67 and 68 may be attached to the circuit board 62, for example, clamped or glued.
  • Advantageously, at the aperture 60, again similar to in Fig. 1 shown, actuators, such as sensor elements, arranged in the surrounding region of the fluoroscopic region 63. For the sake of simplicity, this illustration is omitted here.
  • While in the preceding figures fixed or immovable operating devices have been shown in the form of a diaphragm, show Fig. 5 and 6 movable operating devices, namely rotary knobs. In Fig. 5 a rotary knob 70 is shown. This is at the front of a conventional panel 71, which, for example, a glass ceramic hotplate can be arranged. He sits on a rotary shaft 72, which is connected to a behind the aperture 71 arranged switching device 73. By turning the rotary knob 70, an actuation is made on the switching device 73.
  • Behind the aperture 71, an LED 76 is arranged. This emits light into a second light guide 78. As in Fig. 5 can be seen, protrudes the light guide 78 through the passage opening 74 in the aperture 71 therethrough. In this area, the second light guide 78 is circumferential, that is approximately cup-shaped.
  • A first light guide 77 is light-conductively connected to the second light guide 78 at a small distance therefrom. As can be seen, the first light guide 77 is enclosed in the rotary knob 70. With its front end, the light guide 77 extends into a transillumination region 75 on the front surface of the rotary knob 70. In the transillumination region 75, the material thickness of the front side, according to the invention, is considerably smaller than the standard material thickness otherwise given.
  • Due to the peripheral design of the second light guide 78 above the aperture 71, light emission takes place constantly in each rotational position. The first light guide 77, however, is rather rod-shaped. It can remove light from the second light guide 78 in each rotational position and emit substantially point-like in the transillumination region 75. The attachment of the first light guide 77 in the rotary knob 70 is advantageously carried out by inserting with interference fit or gluing.
  • In Fig. 6 is another rotary knob 80 is shown, which is a modification of the rotary knob 70 Fig. 5 is. Via a passage opening 84 in the aperture 81 of the rotary knob 80 is connected by means of the rotary shaft 82 to the switching device 83.
  • Here, an LED 86 is connected to a second light guide 88. The second light guide 88 projects, for example in the manner of a rod, through the passage opening 84 into the interior of the rotary knob 80. Unlike in Fig. 5 Here, the second light guide is not cup-shaped or circumferentially formed.
  • The second light guide 88 connects to a first light guide 87 and couples light into it. The first light guide 87 is aligned towards the side of the rotary knob 80 at a side transillumination area 85. In this transillumination area 85, the material thickness is reduced compared to the other standard material thickness such that the material according to the invention is translucent and the transmitted light of the LED 86 to the outside radiates as shown.
  • This variation of a rotary knob 80 thus causes a radiation of a light signal or the like in a single rotational position of the rotary knob 80. This is precisely the position in which the rotating by rotation first optical fiber 87 matches exactly with the fixed to the aperture 81 first optical fiber 88th
  • For which use a rotary knob 70 after Fig. 5 or a rotary knob 80 after Fig. 6 can be used in each case can be decided on a variety of aspects and therefore need not be explained.
  • It is pointed out again that the drawings are only to be understood schematically. This applies in particular to sizes or thicknesses or proportions to each other.
  • The invention exemplified with reference to some embodiments can be used to provide arbitrarily designed display devices for use in electrical or electrically controlled systems, apparatus or devices, especially in household appliances.
  • Preferred fields of application are large household appliances, for example washing machines, dryers or dishwashers, which are conventionally provided with non-transparent plastic screens or operating devices such as rotary knobs or the like. are provided. If these are modified in accordance with the invention, then cost-effective possibilities arise for ensuring a maximum of flexibility in the variant formation of display devices. Thanks to the invention can be used for a whole family of devices with different functionality equipment, a type of aperture with prepared fluoroscopy areas, which can then be combined depending on the equipment with suitable lighting devices. Since, due to the invention, shutters with displays and closed surfaces can be created, a maximum of functional reliability is possible with an extremely attractive appearance.
