Definitions

  • the invention relates to a household appliance with a touch-sensitive operating and display device which has a display unit for displaying operating information and a light-permeable carrier part. At least one capacitive sensor electrode is arranged on the carrier part as part of a touch capacitor, which is arranged in overlap with the display unit on the one hand and in overlap with a touch-sensitive actuation surface of the operating and display device on the other hand.
  • an LED display with an associated capacitive operating device.
  • light elements - LEDs - are used, by means of which function signs or display symbols can be backlit.
  • Such an operating and display device is, for example, from the document DE 102 36 718 A1 known.
  • This operating and display device contains an operating panel, which is a one-piece plastic injection-molded component made from ABS plastic.
  • the control panel has a circular fluoroscopic area in which the material thickness of the panel material is reduced compared to the standard material thickness in such a way that the fluoroscopic area is translucent.
  • This transillumination area forms an optical display device - display symbols or function signs are attached to the surface of the transillumination area and can be illuminated by means of a light-emitting element, such as a light-emitting diode.
  • the light element is attached to a circuit board.
  • a sensor electrode is attached to the rear of the control panel, which is part of a capacitive switch or part of a touch capacitor. The sensor electrode is electrically connected to the circuit board and thus to an evaluation unit via a coupling element or contact part.
  • an operating and display device for a household appliance On a circuit board, which is connected to the other controls of the household appliance via a ribbon cable, is a two-line, with Display with fonts and symbols applied.
  • the display is covered by a control panel or control panel, which is provided with transparent, metallic surfaces. These metallic surfaces together with the surfaces underneath form a capacitive switching element that controls the command.
  • the display is equipped, for example, with light elements in LED or LCD technology.
  • Such layers are predominantly transparent to visible light.
  • the ITO layers find their limits when they are applied to three-dimensional surfaces. They are only suitable to a limited extent for this.
  • the carrier part on which the sensor electrodes are arranged has a curved - for example convex or concave - surface, as can be the case with control panels of household appliances, the ITO layers can no longer be used satisfactorily.
  • raw materials are relatively expensive compared to other electrically conductive materials.
  • the object of the invention is to create a household appliance with an operating and display device in which the at least one sensor electrode can also be attached to the carrier part with little technical effort and at low cost, in particular if the carrier part has a three-dimensional - for example a curved - surface having.
  • a household appliance comprises a touch-sensitive operating and display device which has a display unit which is designed to display operating information.
  • the operating and display device also has a translucent or transparent carrier part on which at least one capacitive, electrically conductive sensor electrode is arranged as part of a touch capacitor.
  • the sensor electrode is arranged in an overlap with the display unit on the one hand and in an overlap with a touch-sensitive actuation surface of the operating and display device on the other hand.
  • the operating surface can be touched or tapped by the user in order to operate the household appliance.
  • the at least one sensor electrode is formed from a - at least for visible light - transparent and electrically conductive lacquer and / or adhesive which contains nanotubes made of carbon.
  • the effect according to the invention is thus achieved through the use of a special material for the sensor electrode, namely through the use of a translucent and electrically conductive adhesive and / or lacquer. It has been found that such materials are significantly better suited for application to three-dimensional surfaces than, for example, the so-called ITO layers, which consist of indium tin oxide.
  • the household appliance according to the invention thus has the advantage that the at least one sensor electrode can be attached to the carrier part without much effort even if the same carrier part has three-dimensional, for example curved, surfaces. While the layers formed from indium tin oxide are only suitable to a limited extent for application to such surfaces, transparent and conductive lacquers and / or adhesives can also be applied to concave or convex surfaces without much effort.
  • the operating and display device of the household appliance according to the invention can thus be shaped or configured as desired - it can have a wide variety of geometric shapes without its functionality having to be restricted due to the material of the sensor electrode.
  • transparent and electrically conductive paints or adhesives, which contain CNT are also relatively inexpensive, so that overall costs can be saved.
  • a household appliance is understood to mean a device which is used for housekeeping.
  • the household appliance is therefore a device which is designed for the treatment of household objects, for example items of laundry, dishes, food and the like. It can be a large household appliance, such as a washing machine, a tumble dryer, a dishwasher, a cooking appliance, an extractor hood, a refrigerator, a fridge-freezer or an air conditioner. However, it can also be a small household appliance, such as a fully automatic coffee machine or a food processor.
  • the at least one sensor electrode is attached to the carrier part by screen printing.
  • the at least one sensor electrode can therefore be applied to the carrier part in a screen printing process.
  • the screen printing process ensures extremely precise positioning of the sensor electrodes; on the other hand, it also prevents an unwanted short circuit between the sensor electrodes - for example due to inaccurate positioning.
  • the operating and display device has a plate-like, transparent and electrically non-conductive pane, the front side of which forms the touch-sensitive actuation surface that can be touched or tapped by the user to operate the household appliance.
  • the pane thus represents a display window made of a translucent material.
  • the pane can be inserted into a through opening of a control panel of the household appliance; it can be welded into the control panel, for example.
  • Such a disk which is arranged in an overlap with the at least one sensor electrode and in an overlap with the display unit and whose front side forms the touch-sensitive actuation surface, has the advantage that, on the one hand, the The display unit can be protected from external influences and, on the other hand, the outer surface of the operating and display device can also be designed in a visually appealing manner in a wide variety of ways, regardless of the display unit. For example, different device variants with different panes - for example with different colors - can be provided without the display unit having to be redesigned.
  • the pane is made of transparent plastic.
  • a material can namely be shaped in the most varied of ways, so that a three-dimensional configuration of the actuating surface is also made possible.
  • the pane can also be made from a material that is tinted, in particular in color.
  • a (color) tinted design of the pane is based on the knowledge that the transparent and electrically conductive paints and / or adhesives used do not necessarily have 100% transparency, but the transparency can be between 80% and 100%. If a completely translucent pane were used, the user might also perceive the sensor electrode optically. To avoid this, the transparency of the pane can be adapted to the transparency of the conductive paints and / or adhesives.
  • the design of the pane from a color-tinted material also ensures that any blocking pressure applied to the rear of the pane cannot be seen on the operating side or on the side of the actuating surface.
  • the carrier part on which the at least one sensor electrode is arranged can be formed by the pane itself.
  • the at least one sensor electrode is arranged on a rear side of the pane - opposite the front side.
  • the arrangement of the sensor electrode on the pane has the advantage that the use of a separate support part is unnecessary, and the pane takes on two different functions, namely on the one hand the function of covering the operating and display device and on the other hand also the function of carrying the at least one Sensor electrode. Components can thus be saved.
  • the pane can be arranged resting on the display unit in such a way that the at least one sensor electrode rests on the rear side of the pane on the one hand and on a front side of the display unit facing the pane on the other hand.
  • the at least one sensor electrode thus bridges the distance between the display unit on the one hand and the pane on the other hand or fills this distance. This has the advantage that no air gaps are formed between the actuation surface on the one hand and the sensor electrodes on the other, which could worsen the sensitivity of the capacitive operating and display device.
  • the carrier part is designed as a transparent and flexible film, so that the at least one sensor electrode is arranged on the film.
  • the film can be arranged on the display unit in such a way that the film rests on the one hand against a rear side of the pane and on the other hand against the display unit.
  • the at least one sensor electrode can be arranged here either on a rear side of the film facing the display unit or on a front side of the film facing the pane.
  • the film can be made of plastic. It can be a single or multi-layer film. It can be glued to the pane or back-injected directly using injection molding or injection compression molding processes (IML, IMD technology). With the printed, transparent film, there is no direct printing on the pane.
  • This embodiment also has the advantage that the pane itself does not have to be geometrically adapted due to a screen printing on the back. This enables an even more flexible design of the operating and display device.
  • the display unit is preferably an LED display: it can have a light guide part or a light shaft which is designed to guide light and on which at least one function symbol is arranged as operating information in an overlap with the sensor electrode.
  • the display unit can also have a lighting device - in particular with at least one light-emitting diode - which is used for backlighting or for optically highlighting the function sign when the user touches the touch-sensitive actuation surface in an overlapping area with the function sign.
  • the operating and display device thus represents a touch-sensitive LED display in which a function of the household appliance is selected by tapping the function symbol and the selection or the tapping of the function symbol is signaled by backlighting this symbol.
  • the operating and display device is thus operated by touching the operating surface, specifically in an area of overlap with the sensor electrode and the function symbol. No mechanical movement of an operating button has to be carried out.
  • control panels in which such control devices are used can be designed with a closed surface without an opening, which has the particular advantage in household appliances that no contamination can enter the interior of the device and the closed surface can also be cleaned particularly easily .
  • a thin film with the at least one function symbol can be attached to the light guide part.
  • This can be a writing film or a light mask.
  • the at least one functional symbol can thus be designed in the most varied of ways, regardless of the design of the light guide part. For different country variants or device variants, only different writing foils need to be used in each case, while the other components - in particular the light guide part itself - can be retained.
  • a plurality of capacitive sensor electrodes can also be arranged on the translucent or transparent carrier part in an overlap with the display unit and in an overlap with the touch-sensitive actuation surface, which are arranged at a distance from one another.
  • a value of a parameter of the household appliance assigned to this sensor electrode can be selected.
  • the most varied values of the parameter can be selected or a large number of parameters of the household appliance can be set with the aid of the touch-sensitive actuation surface.
  • each of the sensor electrodes is assigned at least one illuminable function symbol which is arranged on the light guide part in an overlap with the associated sensor electrode and which symbolizes the value of the parameter associated with the associated sensor electrode.
  • the selection of a parameter value can thus be signaled with a function symbol.
  • the A parameter value is thus selected by tapping one of the function symbols or the actuation area in an overlap area with one of the function symbols.
  • a wide variety of functional signs can therefore be attached to the light guide part, which can be backlit by means of the lighting device, namely through the light guide part.
  • the function symbols each symbolize a different value of a parameter of the household appliance.
  • a value of the parameter can also be understood in the present case to mean designations or letter sequences, namely, for example, various operating programs of the household appliance and / or various additional functions.
  • a parameter can, for example, also be an operating program for the household appliance - the name of the specific operating program is understood here as the parameter value.
  • An additional function of the household appliance can also be set as a parameter, for example "easy-iron" or "prewash” in the case of a washing machine.
  • the function symbols can generally include word symbols and / or numbers and / or symbols or symbols and / or combination symbols, such as word-symbol symbols.
  • the operating and display device can therefore be designed to set at least one of the following parameters of an operating process of the household appliance: It can be designed as a parameter for setting an operating temperature.
  • the display unit can have a large number of illuminated function symbols, each of which symbolizes a selectable value of the operating temperature. This embodiment proves to be particularly advantageous in a household appliance for caring for items of laundry - such as a washing machine or a tumble dryer - or in a dishwasher or in a household appliance for preparing food - such as an oven and / or a hob.
  • the operator can tap the desired temperature value on the touch-sensitive actuation surface in order to set this temperature value.
  • the operating and display device can be designed to set a speed of movement of a component of the household appliance - for example a speed of rotation of a laundry drum.
  • the display unit can have a large number of illuminated function symbols, each of which symbolizes a selectable value of the speed of movement. This embodiment is particularly useful for household appliances that have a movable component, such as a laundry drum or the like.
  • the operating and display device can also be designed as a parameter to define an operating program.
  • the display unit can have a large number of illuminated function symbols, each of which symbolizes a different operating program. This applies accordingly to additional functions of the household appliance. Thus, each of the function symbols can identify a different additional function of the household appliance.
