Description

The The invention relates to an operating device for a program-controlled household appliance according to the upper handles the sibling claims 1, 3, 5, 8, 12 and 36 and a method according to claim 50.

There Controllers with microcomputers become more powerful and efficient As they become cheaper, they are increasingly finding their way into home appliances. hereby will be a big one Functionality with many adjustment options available, the Although usually not needed, but if necessary without studying The instructions for use may also be accessible to the less experienced user should. There is always the danger that the user the operating system too complicated, and he only a minimum of the possibilities offered uses. A big Number of actuators and any associated indicator lights on the screen z. B. a stove or a washing machine is confusing and expensive. Therefore, a dialogue operation with the help of a graphic screen display to the variety of settings to manage something. The However, known dialogue systems are compared to conventional Operating systems with rotary and pushbutton switches are unfamiliar and time-consuming in the Operation and require an increased Concentration. When preparing food, can be a fast Action is needed and it is difficult here about one Menu navigation in the Dialogue system to react quickly. The user-friendly operability is, however, a purchasing-critical feature and has top priority in the Development of a useful household appliance

One Problem is also that for a housing of the ad and the control elements usable height the control panel frequently limited is, for. B. in sub-equipment due to a visual restriction through one over it projecting kitchen worktop. With such a dialogue operation under the table, with possibly bad Light and visibility There are particularly high requirements in terms of ease of use, in particular with regard to easily legible, clear display content, an easy to understand dialog guidance and easily understandable arranged and easily operable Controls.

The present application is based on the stove E 9871-4 AEG. This stove has a control panel that is colored in its side areas divided, each in a lower adjustment range with a hob associated cooking stage turntables and one about it lying, display area, in which in small displays with these Turntables set cooking levels are displayed. In the middle Range of the horizontal extension of the control panel is a relative high screen display for one Dialogue operation arranged between the cooking stage turntable protrudes downwards and at its lower edge, lower than the cooking stage turntables, color integrated into the downwardly projecting display area, a control panel is arranged in the form of touch keys. This is the proven and familiar optically clear outline of a control panel in a horizontal continuous adjustment area and a horizontally continuous display area, each with the same height, broken, which is less clear is. Execution the buttons as a touch switch in the area a vertical control panel under the table is also disadvantageous. The user must first with look for the right switch on the flat surface, before pressing it with your finger can. So he is distracted by the ad. In the ad with Representation in several lines are two main selection fields on top of each other or main processing areas for Control variables, once for oven functions or programs and on the other for Program parameters such as temperature, weight or time arranged. The programs or values in it are switched on with the on / off switch or an option key called for display and are above each a separate navigation device in the form of a separate button pair by so-called rolling or scrolling adjustable, these two pairs of buttons on different Ends of the row of keys are arranged. For automatic programs can in another selection field of the display next to the programs Weight indication appear, which can be adjusted with the same pair of buttons is like the other parameters in the other selection box. This is confusing and getting used to.

From the DE 196 06 115 a control panel of a household appliance is known, which has two, partly numeric and partly alphanumeric graphical displays. In the first display, all selectable programs are shown in plain text in a multi-line and multi-column table as the first control variable and can be selected by means of a turntable arranged underneath with a vertically displaceable marking in the display. In a second display arranged next to it, as a further control variable, a single-line value of an assigned parameter, e.g. B. the temperature proposed, which is changeable by means of a pair of keys arranged under this display and can be actuated by means of a confirmation key, whereupon a next adjustable control variable or another parameter appears in this selection field or processing area. The set or confirmed parameters are displayed one above the other in a status field of the second display to the right of the selection field. This concludes on the right, a third setting field, in which microwave defrosting programs are displayed in a multi-line plain text list for selection. The selection from this plain text list is made with the key pair, which otherwise serves to change the parameter values. The selection in three very different selectable selection fields by means of two navigation devices is not easy for the user to understand. There is also limited space available for programs in the selection list in the first ad, since the font may not be too small. Furthermore, the arrangement of the controls in several rows of keys, z. T. one above the other confusing. For example, memory programs are programmable with buttons 14 and 18 on the far right, far from the left program selector. It is also confusing that the status field with the already set parameter values in read direction after the main selection field for parameters lies between two selection fields of the same display. Also, it is not clear how to return to setting an already edited parameter without canceling the setting.

The European patent EP 0 976 862 B1 shows a washing machine with a multi-line high screen display, at one side edge, the lines associated keys are arranged, which can be acted modifying on the program parameters displayed in the lines. A correspondingly constructed washing machine LAVAMAT 1820 AEG has in addition to the other side of the screen display a turntable for vertical displacement of a marker in a display of selectable programs shown in the display list. This design also has the disadvantage of a high height of the display. This would be less problematic in a washing machine per se. But you want to different devices of a device series with user-friendly similar or

similar Equip control devices, too the conditions described at the outset with reference to the hearth of AEG in stoves with cooktop controls on the control panel of the oven considered become.

From the EP 1 174 538 A2 is an operating device of a washing machine is known in which a setting is done in dialogue with a display. By means of a multi-function turntable, in a setting process, depending on the context menu, a marker is vertically moved in a list (column 4, lines 50 to 54) or a list rolled or a marker moved horizontally between selection boxes (column 9; lines 15 to 19). Although the display fields (gap 8, lines 15 to 20) arranged differently in each display level for the different control variables (clue 8, lines 15 to 20) may provide clues to the respective mode of operation of the turntable, however, one may from such a small display, if any in a vertical plane under a Table edge is not expected too much. The user will have little patience in stooping position. So the operation remains confusing at least for the less experienced user. In addition, keys arranged under the display are assigned changing functions as the settings progress, initially serving as program memory keys and later as function keys. This, too, is confusing, even if the display arranged very close above displays pointers to the key mapping. A built according to this application, quite multi-part display must be relatively high, if the font or the symbols should still be easy and quick to read without looking too much or the device must be installed with the control panel in face height.

The EP 1 278 016 A2 and the kitchen stove H4540 Fa. Miele show a dialogue control similar to the EP 1 174 538 A2 for which essentially the same applies to the previous one. In addition, it is proposed there to associate the controls of the dialogue operating device to the display area, while the cooking stage turntable are arranged outside this range. 1 this application shows a centrally located between the right and left of it, arranged at different heights cooking stage turntable display and close underneath, low-lying, spaced-apart controls of the operating device. For this purpose, the above applies to the stove E 9871-4 AEG said.

From the above already discussed EP 1 174 538 A3 It is also known, with five buttons arranged under a display to make individual programs callable. The disadvantage here is that as described above, the keys subsequently have other functions in the dialog method. A long list of other available programs can be accessed as a submenu by selecting and selecting the term "program selection" in the display, however, program selection is via submenus for quick operation in the kitchen, such as when guests are expected and Housewife is nervous, unfavorable and if possible to avoid.

It is also known from washing machines of various manufacturers, in addition to a setting of control variables by means of a dialogue operation to set additional control variables via keys. This has the disadvantage of increased number of keys. Furthermore, this has the significant and some users some confusing disadvantage that depending on the selected program type, each of the keys each functionally have to go. In the present case, on the other hand, only the sensibly adjustable control variables are displayed.

Of the The stove E 9871-4 from the company AEG, which was described in the introduction, calls with the switch-on a big list available Work programs, which then scroll through a window of the ad are and shows in a submenu more Work programs. This requires when looking for a more specific one Program long scrolling.

at the stove H4540 of the company Miele is in a relatively high indication a long program list is displayed in which a cursor is selected.

Of the Invention is based on the object disadvantages of the prior art technology to avoid or reduce and in particular the ease of use to increase.

These Task is solved by the feature combinations of the independent claims 1, 3, 5, 8, 12, 36 and the method of claim 50. Drawing these solutions characterized by their simplicity and efficiency. The operating system is mainly because of its consistently largely uniform Conception easy to learn and easy with optical and tactile user guidance detectable and therefore fast and safe to use. The display content is simple and clear built and enabled at a relatively large Character size and good Readability a relatively small and above all low screen display. This in turn gives creative freedom and allows a clear overview Integration into the overall concept of a control panel with a clear, tidy Outline and a good, clear Placement and assignment of controls especially at under Equipment for installation under a kitchen worktop. The operation becomes clearer and more convenient. The overall arrangement is a powerful, simple, home appliances, in particular under Equipment adapted dialog system that guides the user through clarity, Clarity, simplicity and beauty appeals and animates to use.

The solution according to claim 1 is characterized by its uniformity by a control element or a function of a multifunction control element with a always the same or at least visually consistent Effect on the display can affect all entries. This is easy and memorable for the Users and the previously known devices and patent applications to dialogue operations in household appliances so unknown. Avoidance different movements triggered by a control element function or actions in the display makes the operation clearer, faster understandable and therefore safer.

To the claims 1 to 3: Two in opposite directions Directions Modifying Controls can also to a rocker switch or a turntable in two directions turntable be summarized, which also in a third direction as a driving device can act by the same time as a push-button is tippable. The latter is known from flocks of the Fa. Miele. Important Here is that every feature of such a multifunction control always the same effect, especially on the movements in the Maintains display and also no two navigation devices for different control variables available are like the stove E9871-4 of the company AEG.

It It is important that all tax figures are consistent with a drive control or a directional function of a Navigation device are controlled, as far as they are not with the Calling a group of control variables as their first entry already when they appear in the ad controlled and immediately changeable are. Preferably, each first control variable entry is automatically activated and every second and further control variable entry by means of the drive device controllable. With the in reverse direction Actuating drive direction function can also all already edited or abandoned entries the groups are redirected. Each is a separate one Directional control to prefer, because it is the directional component the control or navigation to the right or left, up or below to highlight the entries there, as seen from the marker, what the operation obvious power. The preview of the control variables pending for processing next to each driven or standing in a processing area Tax size facilitates the operation. You can see what might still be set. The different controllable control variables can be side by side or with each other be arranged. Conveniently, becomes a four-way navigation device used with four directional functions, two of which are in opposite directions. This is always a return and correcting possible, without all the entries would have to be rolled through in the circulation. The four-way navigation facilitates the operation.

The navigation takes place in a three-dimensional conceivable table with stepped control variable entries or parameter values permitted for the selected program as branches or chains in the third dimension. In a display with a preview to the entry controlled adjacent entries of the control variable is the entries branch of each triggered control variable tilted in the display level and displayed in sections. Rolls or sheets are understood to mean the pushing through of such a branch by the display, whereby depending on the design of the display only one entry is shown as a visible section or two or more entries are displayed with preview and in the display as well as into or out of it this can hike out.

in the the simplest case has the device or the operating device only one, all work programs comprehensive Group of user-adjustable control variables z. B. same with the Switch on the device is called for display and possibly a supplementary basic tax group. The on-off control can be a preselection control in this case at the same time. However, it is for a quick and easy operation a division into several Groups of advantage (see the claims 5 to 7).

The solution according to claim 2 relates to all in the embodiments illustrated display designs or dialog designs with the Preview and control in the horizontal direction of the different Control variables in the Display. this makes possible the horizontally stretched, relatively low indicator, which looks good in the technical and creative meaningful overall concept insert the operating device and devices and allow large, easy-to-read entries. The processing of the different control variables in one processing series or only one editing area is convenient for the user. He does not have to search where else parameters are set.

Claim 3 (see in particular 4 - 11 and 24 - 28 ) relates to a preferred embodiment in which all entries are retractable and editable into a substantially fixed area of the display, which makes the operation pleasant and quick. The first control variable of a group of control variables called up for display, which may be a program or a parameter assigned to a program, is already activated in the selected processing area with the call.

Preferably the operation takes place after a program start according to the changed until the start time entries and as far as indicated, adjustable and other control variables in the Operating phase were not processed, alternatively according to the Operating device for it proposed entries or values. To have to So not all or even no control variables controlled and edited be, if you have the suggestions the operating device takes over. The start is preferably carried out by pressing a start button, can but also done automatically z. When after a setting step a certain time no operation took place. Important for a quick information about the operating status of the device is that the display in operation after the program start, z. B. by at least partially color inversions, clearly different is as in the operating phase. The main parameter z. B. the working temperature preferably remains always, even in working mode, displayed and is controlled with the start and expediently, except possibly with automatic programs, can be changed at any time. The timing variables become only effective if the user has changed them from their default value "0", the control device still check the sense of adjustment and may possibly give an error message. Appropriately be in the operating phase and in working mode, all control variables that are processed in the operating procedure were shown in the display, at least as symbols.

Of the in claim 5 proposed entry into the dialogue control means Program group preselection controls has the advantage of a great sense of purpose for the User as an introduction to two "different Worlds "and shortens them Lists of each adjustable work programs, what the clarity improves and facilitates operation and, above all, faster power. A shortening The lists in known devices partly by a hierarchical Selection structure with program lists in submenus reached, but the here proposed group classification is not found. A Program selection via submenus is for a quick operation in the kitchen unfavorable and if possible to avoid. This especially if the operation s.einer under appliance under the edge of the table, in low light and visibility must be done.

The Work programs of the different groups differ approach, preferably by machine orientation or problem orientation or in the type of the main parameter. For example, has an oven Machine-oriented heating programs with the operating temperature as the main parameter and problem-oriented Automatic programs with the type and weight of the food as Main parameters and a washing machine textile type programs with the Washing temperature as main parameter and pollution type programs. In automatic programs, the oven z. B. the type of food, its weight and its desired Entered final state and it is left to the oven for this purpose suitable temperatures and to choose cooking times.

Furthermore, a further division according to claim 6 is appropriate. So with the call of one of the pre-selection groups preferably only the first accessible to a selected work program associated with major major control variables. A group of other less important or rarely used additional control variables also associated with this work program can be called up for display with a supplementary control variable control element for a previously called work program, wherein a further control variable group can be provided in addition to a time control group, preferably all others left by the user adjustable control variables includes to avoid individual control variables controls. In a washing machine main control variables z. For example, the wash temperature and spin speed and possibly "prewash on / off" and additional control variables eg final spin on / off "," anti-crease on / off "and" buzzer on / off "are another group of this type. The time settings also contain a short-term alarm clock, which can also be used independently of the operation of the device, and therefore can also be called up independently of a previous selection of a program, which also applies to the group of basic settings in which among others Control variable "time of day" is included. With their call, the additional control variables preferably displace the entries of the program and the main parameters into a status area of the display. The entry of the first control variable of each group is controlled by the call in the display and a possibly existing second is also displayed for preview. All control variable groups are expediently consistently processed in the dialog method by demand-driven control and changing by means of the navigation device, whereby the operation is easy to learn and executable.

The Division into the group of main and auxiliary parameters is psychologically very important for a simple operation. It gives the inexperienced user one Selection help not to overwhelm him and lets the experienced user all possibilities open. Here is to think fast, stressful kitchen operation. The Limit of this division is not sharp, but according to expediency for the device type to draw. It is known from washing machines of various manufacturers in addition to the setting of control variables by means of a dialog operation Additional control variables via buttons adjust. However, this has the disadvantage of the increased number of keys the essential and for the user some confusing disadvantage, that depending on the selected program type each of the buttons must be inoperative. In the present case on the other hand, only the respectively meaningfully adjustable control variables in the Display is displayed. With the timing variables, which can not be combined arbitrarily are, can with the setting of one size another then no longer meaningful deleted from the group.

The Additional control variables and the time control variables become preferably not their turn when they call for presentation the main control variables attached but occupy the processing suite and displace the main control variables including the Designation of the chosen Program in a status area of the ad, so as possible many of the additional control sizes clearly in find space for the ad. When the additional control variable preselection control element is pressed again in the processing series, the state that existed before the connection restored while in the status series the additional or at least by an icon be displayed as made.

To Claim 8: For Fast, safe operation is the design of the control panel of the operating device containing household appliance of greater Importance. This is especially true for Cookers, in addition to an operating device for an oven also Controls for a hob included. The claims 8 to 13 relate to the appropriate integration the operating device in a control panel, taking into account especially is that the user with the eyes as possible in the operations in the display can remain and therefore the control panel series designed is that she can be served more or less blindly. By an arrangement of the Bedienereiereih a preferably clear Distance, under the display will be avoided, that the fingers of the user a fast optical recording of the content by concealment or interfere with close movements. The arrangement of the cooking level adjusters at the same height in the operating area facilitates quick orientation and operation.

In the ad can as a guide the line-like horizontal next to each other displayed entries the control variables with sorted in the reading direction of decreasing importance of the control variables and with normal operating progress, as required, in reading direction be controlled sequentially. Furthermore, the controls of the line-like horizontal control element row as a guide at least until finally the navigation device according to a, usually occurring in normal operations temporal sequence be ordered and depending on the case selected controls be operated sequentially in the reading direction, the series preferably starts on the left with the on / off switch. and end on the right with a start control can. Also these parallels and matches bring uniformity and sense in the concept and make the operation comfortable.

different equipment a cross-product device series of a manufacturer such as stoves, washing machines, dishwashers own to standardize, in turn, the usability of the various equipment simplified, a corresponding, same or similar arrangement of the display and the controls series. The organization proposed here of the entries in the display allows a mainly horizontally stretched aligned low display, which facilitates such integration, wherein to take into account is that with all sub-assemblies the view of the control panel through the projecting worktop limited is and therefore the upper areas of the control panel for accommodation the ad are not suitable when the user is at the Do not bend down too much should. The display area and the operating area are preferable creative z. B. color from each other.

The Navigation device has a drive device and a change device on, each one directional function or two opposite directional functions exhibit and spatially to a panel group or a multifunction panel combined with at least two, preferably four Stellrichtungen are. The series of controls extends advantageously horizontally under the display, the navigation device preferably approximately centrally located under the display and as a central element can be arranged approximately in the middle of a row of controls and preferably felt by the rest Different operating elements. In this case, as a change device, a turntable serve, which is preferably rotatable in both directions of rotation for pushing a marker vertically over several rows or rolls several programs or parameter values "quer, z. B. vertical "by a in the Height fixed Machining series, each in two directions. With the turntable the user has something tangible in the hand, to which he can hold on and the spatial Orientation especially to the other controls and the Ad gives. However, the changing device may alternatively also two on top of each other having arranged controls, preferably non-latching Buttons or a push-button rocker with horizontal axis, z. B. in the form of a circular disk for a recognizability of the change device, according to the front surface the turntable of another device of a design together matched Set of devices like dishwasher, Oven or washing machine or a stove according to one Rotary knob of a cooktop control of this stove. The rocker switch jump over the Control panel and preferably also the other controls something before and is due to their shape felt or on the control panel palpable.

When Control device advantageously serve a right next to the change device and preferably also a left side disposed directional control, the can be designed as a non-detent direction key, where appropriate between the direction button and the adjacent button of the control panel a sensible and visible small distance greater than the distance between the other controls of the series. In the present case more mobile Posts or a moving marker in the display, are the directional buttons for navigation to the right and left more obvious and fit better in the overall concept as a simple confirmation button.

The Control row summarizes according to a preferred embodiment all controls of the operating device including the on-off control together. In the case of a cooker with control of an associated one Hob from the control panel of the oven, this is true for the operating device of the oven in the device On / off switch is integrated. The cooking levels are not but integrated into the control element series of the operating device side of this and at a height with everyone separated for arranged. The navigation device is preferably located approximately centrally under the display and can be used as a central Element may be arranged approximately in the middle of a row of controls and preferably felt from the rest Different operating elements. In this organization, the User, probably at the beginning of the operation with the eyes the Fingers to the on-off switch follows, left outside from the on-off switch coming to the navigation device and the about that lying display led. This applies in particular in the case of the claim 11 described above Arrangement of controls in the most prevalent temporal Operating sequence and in reading direction progressive operation. This is a not unimportant contribution to the various measures user guidance, who make the service more sympathetic and impatient and hectic Cramping in the fast kitchen operation Counteract and thus the operation more pleasant and faster do. By an arrangement of the control panel in a preferably clear distance, under the display will be avoided, that the fingers the user a quick visual capture of the display content interfere with coverings or close movements.

The controls of the series next to the changing device of the navigation device advantageously differ palpably from a control surface in or on which they are arranged, being keyboard-like or inserted into gaps in a rib of the control surface one, the finger form the user's leading, substantially closed row. They are preferably shaped or held or arranged at small intervals so that they can be felt individually, blindly. The controls preferably project easily over the control surface, but may also be arranged in a groove-shaped depression of the control surface leading to the user's finger. Furthermore, the controls can also be designed as arranged behind the panel touch switch, which respond to touches of the aperture surface in their area. For haptic user guidance in this case, a guide rib profiled to recognize the keys is expediently attached or raised on the diaphragm surface. The key areas can also by sublime z. B. imprinted symbols for a blind operation, which can be used, moreover, on or next to other controls. Due to the special design of the series, the operation is facilitated by fast, blind, haptic orientation. This is important because the user must keep an eye on the display for fast operation. Beginning and end of the series are tactile and the intervening controls z. As keys due to the systematic arrangement and the other tactile navigation device easily findable and blind operated for the experienced user. The paths to be covered by the user's fingers during the operating phase are pleasantly short.

A significant reassurance of the user and thus operator safety assumes that all controls always have the same function like program group call or control of the control variables in one Direction or the same multiple functions as Change in two opposite directions, Additional control size and timing control call and -back, Device-off or Keypad On-Off or Start-Pause retained.

The Controls preferably left of the navigation device include at least one area code for calling one given program group for display in the display as adjustable Control variable. there can be the device on-off control simultaneously serve as one of at least two area code controls and with switching one of at least two program groups call, with the user preferably in the basic settings can choose Which. As a result, an operating step is saved in many cases. Furthermore, can the controls, preferably left of the navigation device at least one further program group preselection control element for Calling a memory program group include user-stored, finished programs and / or a control for calling a special program, eg. B. one Machine-cleaning program.

Further can the controls at least one preferably right of the navigation device arranged additional control variable operating element include, after the control or selection of a program a group that is not always necessarily set, usually less important, additional Control variables like the time control variable group with the control variables duration, Start, end and short-term alarm callable in the display for adjustment is.

you like the stove H4540 of the company Miele in a dialog operation get along with two or even a single control. This is elegant, but makes the device somewhat repellent and difficult for many User operation, which then largely on submenus in the dialog he follows. The combination of the navigation device proposed here with a few, purposefully used selector switches makes the operation more pleasant, faster and safer.

The Navigation device may have a light indicator that is lit. if by means of a setting is possible and the z. B. one Has light ring around the turntable. It can control the controls have luminous directional arrows assigned to the control device, which preferably indicate by their illumination of the possible directions of adjustment.

The have not belonging to the navigation device controls expediently in each case a light on, after pressing the respective control element lights up to show where you stand, with the light displays preferably a substantially closed beam over the row of controls form. The light color is according to a preferred embodiment a medium to bright blue, which on the one hand reassuring and clear, but it also has a stimulating effect. This light color promotes the aesthetic beauty the operating device and makes them sympathetic and tunes the user Positive in the approach to getting used to the familiar dialogue. The light display of the navigation device can from the other controls deviate and z. B. slightly pulsating or another light color to reflect on the different function of the light in the two cases once as a ready display and on the other as a status indicator to point.

The series of processing in the display is preferably substantially fixed in height and the controlled quantity controlled by vertically rolling its various entries into the processing row changeable. A stationary machining series facilitates orientation for the user. In this direction also acts that the display according to a preferred embodiment, to make their contents clearer, in the operating phase by lines and / or shading and / or inverse representation in the entries receiving areas is divided to adapt to changing sizes or Lengths of the entries are preferably flexible in their size, in particular in their horizontal extent.

Of the Processing area expediently forms with one next to it arranged control variable preview area a horizontal processing series, where in the preview area as Entry or entries one value of the next controllable parameter or values of several parameters next to each other standing in line. Furthermore, the display above and / or below the processing series a change preview series or over and / or have a change preview area under the edit area, in the one or more possible selectable Entry of the controlled tax quantity is. The preview areas give the user hints about what he can do next and make it easier thereby the operation. Conveniently, will be a change preview For the sake of uniformity, all control values are shown, even if only between two entries how to choose ON and OFF is, but for the clarity preferably always only at the respectively controlled control variable.

According to one preferred embodiment the entries each adjustable in the dialog control variables in the preferably single-line Processing series flow text-like strung together and can preferably flow along the processing line. Conveniently, the Entries out the processing series or the display and preferably also again in this back flow. flowing text is defined in Wikipedia as follows: "as body text is called in the pleading Text in one piece without interruption by heels or headings continued becomes. The text "flows" from one filled Line in the next, the line break results from the available type area width and not from the point of view of content or design. "www.at-mix.de states:" Ongoing entered text without fixed division. The word processors let the text "flow" like on a string of pearls, and the words will be redone if necessary distributed on lines. The text "flows" only in certain Limits ".

In the case of the present operating device, the space occupied by the entries in the processing row is preferably measured flexibly according to their length. If due to lack of space in the processing row are not yet displayed additional control variables in a memory of the operating device, you can view the transition from memory to the processing line as a line break. In the case of a line break from the processing series into the status series, a conversion into symbols is sometimes carried out in abbreviation in order to accommodate more. Each entry, preferably in plain text and preferably with dimensions such as degrees Celsius or rev / min for self-explanatory labeling gets the place he needs, preferably in standardized lengths z. B. occupy a maximum of half or a third or a quarter of the width of the display. Most of the time you will choose slightly larger distances between the entries than in a normal text, so that the entries are easier to distinguish between each other or so that they are more easily distinguishable. The font size is preferably uniform in the processing series. The mark z. B. in the form of a frame or a contrasting area is preferably flexible in size to accommodate different lengths entries. It may also be appropriate to display the entries of the processing series not single-line, but two-line, which accommodates more control variables in the display side by side. However, even a single entry can be carried out in two lines if it is particularly long (cf. 11 ). Any two-line entries flow as two-line blocks. If not all entries fit into the mostly one line row, then the missing ones must be rolled out of the memory into the display. According to a modified embodiment with activation by means of a moving marking, the first control variable "programs" always remains in its place in the processing row during the operating phase, while all other control variables next to it are horizontally rollable.

Out the processing series preferably left outflowed, overflowed Posts can in a lower or preferably above the horizontal row of the processing series be at least z. T. abbreviates or turns into symbols can be indicating that the corresponding tax code has been processed or at least controlled or marked for processing has stood, what the overview of the each setting state easier. Timing variables only displayed if they have been set. Become symbols preferably right-justified displayed and in their area, the dividing line of the status area they do not need more space and quick readability disturb. text messages are expediently left justified shown.

The entries of the control variables juxtaposed in the processing series can be of decreasing importance of the tax in the reading direction orderly and controllable in the reading direction one after the other with normal operating progress, which saves a long search for important parameters. In this case, the main parameter z. B. the working temperature or z. B. in automatic programs, the parameters to which the user may also still have the most likely still work changes in the change requests, always displayed and preferably always controlled after the start and at any time immediately adjustable with the change device.

The Display can be changing and also animated symbolic hints Operating options, z. B. directional arrows or pointing to the change device Arrow circle symbol represent and in a lateral, preferably Right section of the editing area by a circle arrow symbol indicate the turntable of the navigation device as a change device. The directional arrows can be shown in a halftone screen. This allows as Note on the next possible Setting steps z. B. an emphasis by changing the contrast, the can also be flashing. The entries are expediently, z. B by the addition of a dimension specification at least in the processing series, self explanatory and the display or its mask or division, as more or less solid component except possibly symbolic Notes on operating options and possibly the time by the way preferably no text or dimensions.

In the operating phase can in the action instructions or temporary help information status series in place of the control size entries and possibly also the usual time there or next to these representable are, for. B. when the user hesitates to operate. About one Information control can Also, more extensive information is called, the whole Fill in the ad can.

The Display may preferably be in the status row after the program start, in the case of a given or set working time the temporal Represent work progress in a progress bar and possibly display in clear text or by icons after the program starts, which working phase z. B. Heating is in progress. Furthermore, if the entries to be displayed not all together in the status row place, groups of entries in short-term change z. B. each about 4 seconds are displayed.

The independent, siblings, claims 1, 3, 5, 8, 12 and 36 can be combined differently with each other and for the claims 1 to 7, 11 and 33 to 48 will be added the genus method claims, the relationships of the claims to each other and the possible combinations the method claims unchanged remain or correspond to the device claims. These device claims are in itself very functional, procedurally formulated.

The terminology used in this application is predominantly colloquial and used only in exceptional cases and possibly coincidental terminology Computer science, which is therefore not too narrow in the present context should be seen. It is the visible representations and processes or apparent events on the graphical user interface, the ad described the electronic and programming technology causes in various ways can be. The present application is generally vertical Control panels off, but are control panels z. B. at Toplader washing machines also aslant or horizontally and could by the way, too be arranged on a remote control. In this case, they are the same here used terms above and below to translate in the back and front and a vertical extension as an extension to the user out or away from him. The term "edit an entry" means this entry to control and accept or change. The term "setting" is the driving and change of entries subsumed. The "changing" not only includes change this predetermined or proposed by the operating device entry values, but also, z. For example, at the time settings, enter a Value of zero. Moving a marker can be done by jumping on the controlled entry and also when rolling or "flowing" can the Jump entries.

Operating methods or operating devices according to the present application can be used not only in ovens, ovens or washing machines, but in dishwashers, fryers, coffee machines, microwave ovens and other household appliances. It is expedient to apply the same operating concept with the same operating elements as far as possible across different creatively matched devices of a device series of a manufacturer, since the owner of several such devices then knows the operating concept and can operate it more easily with the various devices. In this case, modifications may be expedient for the sake of simplicity or cost reasons. For example, in a dishwasher that has a few programs, the display may be lower, single-line and without status. Furthermore, instead of a turntable of the navigation device and a cheaper rocker switch ( 450 ) are used, the function for the recognition in the same way as the turntable with other devices of the same Ge rätereihe is centrally located in a row of controls and seen from the front a circular shape as the turntable ( 50 and 250 ) owns. Also this serving as a change or vertical device switching rocker ( 450 ) may be raised slightly above the remaining keys of the control panel row to give the user a tactile, haptic orientation on the control panel when operating beyond their shape deviating from the other keys.

The in the 1 to 11 illustrated Household Unterbauherd 12 has an oven 14 standing under a cut out kitchen worktop 16 is installed and an associated hob 18 , the deck side in a section of the worktop 16 is used. The oven 14 owns a between a lower oven door 20 and the worktop 16 over its entire width extending control panel 22 , This is in an upper display area 24 and a lower operating area 26 divided, each with a constant height over the entire width of the oven 14 extend and preferably differ in color for orientation of the user in its surface. The operating area 26 has a horizontal row of controls in the middle of its width and medium height 28 and right and left of it distributed at the same height four cooking stage turntable 30 to 36 to operate the hob 18 , About the turntables 30 to 36 are in the display area 24 four cooking level displays 38 to 44 arranged. Between the latter is above the middle of the control line 28 an ad 46 the oven is centrally located. At the display 46 it is a screen display or a full graphics dot matrix display.

The control panel series 28 and the ad 46 are components of an operating device of a computerized control of the oven 14 with several adjustable control variables, eg. B. program groups or lists of selectable work programs and each program programs associated parameters with which the user is required for the respective operation operating program is adjustable. For this the in 2 Larger control row shown 28 in the middle and in the middle of the display 46 a four-way navigation device 48 with a central turntable 50 which forms a change device in the form of a two-way vertical actuator and is freely rotatable through to the right and left, which in the display 46 shown entries of the control variables are vertically scrollable or blätterbar. The turntable has a slightly curved front surface 51 , As a drive device in the form of a horizontal adjusting device serve a left directional key 52 and a right directional button 54 that left and right next to the turntable 50 are arranged on a horizontal axis crossing its axis of rotation and are used for navigation to the left and to the right. This is followed by a horizontal row of lower horizontally stretched, adjacent keys to the right and left, for easy removal of the navigation device in a small distance or a gap 74 and 76 from the directional buttons 52 and 54 kick off. The left row starts with an on / off button 56 , This is followed by a program group preselection key 58 on, with which is a control preset area with work programs with conventional heating modes such as top / bottom heat, top or bottom heat alone, and hot air for display and selection in the display 46 can be called, whose main parameter is the operating temperature. With the next program group preselection key 60 For example, a control variable group can be called up with automatic programs, which then ask for the type of food, its weight as main parameter, desired final state and possibly further information, whereupon the operating device automatically determines the type of heating, the operating temperature and the operating time. The next program group preselection key 62 inside a list of programs that the user has set and saved according to his needs. Notwithstanding the illustrated embodiment could be present in this left-hand row another key with a self-cleaning program, eg. B. can be selected with pyrolysis. The key-wings projecting horizontally from the turntable are symmetrically the same length and with the same number of keys for easier orientation.

The right row of keys starts with a default key 64 with a group of other control variables such as language, time of day, signal volume, screen brightness, etc. in the display 46 can be called up for adjustment and can be switched off by pressing the button again. This is followed by a lock key 66 on, with the whole control panel locked or rendered ineffective and can be unlocked again by pressing the button again. Right next to it is a time button 68 with the addi tional, not always necessarily to be set timing control variables duration, beginning, end and short-term alarm callable in the display and by pushing the button again reset. The series closes with a start / pause button 70 , Deviating from the illustration, the right-hand row of keys can be provided with an additional quick-heat button. All these controls of the control panel 28 are essentially occupied from left to right as they are needed in normal operation in the setting in chronological order, of course, as required, individual keys are skipped.

The in the presentation of the 2 under the control panel 28 arranged arrows and numbers in circles indicate that the device firstly with the left most extreme control 56 secondly set with the following controls and third with the rightmost control 70 is started. All buttons of the control panel 28 Rectangles are horizontally stretched horizontally as two keyboard groups, with non-latching short-stroke keys that feel something over the front surface 72 the control panel 22 and are shaped or held so that the transition of the finger from one key to the next is noticeable.

Above the left row of keys, with a small gap 74 to the left direction button 52 connects is a lightbar 78 arranged, consisting of individual, low, in each case over the entire button width extending light indicators that light up when the corresponding button was pressed. Likewise, it owns with a small distance 76 to the right direction button 54 subsequent right button row such a light bar 78 , The light color is blue. The navigation device 46 owns on the directional buttons 52 and 54 light arrows 53 and 55 and a turntable 50 surrounding light ring 84 that light up when settings can be made with the navigation device. The function of the light indicators of the left and right row of keys and the navigation device are therefore different, which can also be indicated by a different light color. Furthermore, the light arrows work 53 and 55 with the dialogue control together and show by their illumination in which directions a setting is vornehmbar.

The turntable 50 is essentially circular cylindrical and jumps clearly over the key row and direction keys 52 and 54 before and is z. B. lowered for cleaning purposes ver. Its front surface is slightly convex, slightly arched towards the middle. The spatial design of the control panel series 28 gives the user a haptic guidance during operation. So he can easily on the left outside the slightly projecting first power button 56 by the way, according to a modification, a pre-selection program group can also be called up for display. This program group can be determined by the user by means of the basic setting control variables and z. These include, for example, the standard heaters or the user-defined storage programs. The finger can then, sliding along the slightly projecting rows of keys, blind the navigation device 46 find where he is at the projecting turntable 50 with which he then settings in the at a distance directly above display 46 performs. Also the start button 70 is easy to feel as the end of the series again. These sensitivities are important because the user wants to act quickly with his eyes as possible when viewing 46 should remain and especially important in the arrangement of an operating device on a base unit in the low position under a table edge.

4 shows the illustrations in the display 46 after pressing the program group button 58 to call the programs by heating modes. The ad 56 is in the setting or operating phase divided into a lower, left processing area 86 , which is almost three quarters of the height of the ad 46 occupies and whose width is variable. Through this editing area 86 extends across the full width of the ads 46 a horizontal machining series 88 , in which control value entries ie list contents and parameter values of the control variables can be displayed. This processing series 88 can such. B. in the case of 10 and 11 For the operation shown after the start also be once two lines, if the desired information is not to be housed in a single line. The right edge area of the editing area 86 is as a reference section 90 designed, with directional arrows up and down and a circular arrow symbol that flashes to indicate that here with the turntable 50 a setting is vornehmbar. The arrow symbols indicate by brighter or darker or flashing, in which direction a change is possible, that is, in which direction rolling of the entries in the editing area 86 standing control variable by means of the turntable 50 can be done. Right next to the editing area 86 closes a preview area 92 , through which also the processing series 88 extends and as an entry a default value of a parameter supplemented by a designation z. B. a unit of measurement, such as degrees Celsius. It also contains the processing series 88 to the left, in the preview area, a right-pointing arrow 96 , which implies that with the right directional key 54 a navigation to the right and in the preview area 92 standing control variable can be controlled for adjustment. Another directional arrow 98 right next to it indicates that at least one further control variable is available in the memory for possible adjustment and by means of the direction key 54 in the ad 46 can be rolled. Above the editing area 86 and the preview area 92 is one, the remaining height and the whole width of the ad engaging status area 100 with a status series 102 whose characters are slightly smaller than those of the processing series 88 , The presentation in the preview area 92 and in the status area 100 done with bright characters on a dark background while the editing area 86 Inversely, it has dark representations on a light background, whereby it is marked bright, in order to indicate that the value of a control variable currently standing in this area is marked and by means of the turntable 50 is adjustable. The status area 100 , which can show the time, help texts and settings, is by a dividing line 101 separated from the lower areas that serve the setting.

weitere Heizarten mit Drehwähler...". Gleichzeitig wird der untere Richtungspfeil 102 im Hinweisabteil 90 des Bearbeitungsbereichs 86 animiert, um anzudeuten, dass es sich um den ersten Eintrag der Liste handelt und eine Verstellung nur durch Rollen nach oben in diesem Fall durch Drehen des Drehstellers 50 entgegen dem Uhrzeigersinn erfolgen kann. Dies ist in 5 dargestellt.The display content of the display 46 in 4 appears after pressing the program group pre-selection key 58 , whereby a corresponding main control group is called, which contains only a more important part of the adjustable control variables. "Heating modes" is the first control variable in the form of a program list, the first program "Upper / lower heat" after pressing the preselection key 58 in the editing area 86 appears. If the user does not do anything for a few seconds, appears in the status series 102 the help text "

other types of heating with rotary selector ... ". At the same time the lower directional arrow appears 102 in the notice section 90 of the editing area 86 animated to indicate that it is the first entry in the list and an adjustment only by scrolling up in this case by turning the turntable 50 can take place counterclockwise. This is in 5 shown.

6 shows the situation after rolling the second list value "3D hot air" of the control variable "heating modes" in the editing area 86 , If the user wants to use this program, he could now do it immediately by pressing the Start / Pause button 70 start. However, he can also use the left arrow 96 in the preview area 92 follow and the right direction button 54 to press. He then rolls the proposed parameter value "200 ° C" in the preview area, together with the unit of measure, to the left in the editing area 86 ( 7 ). In doing so, the first control variable "3D hot air" flows, reduced in size to the top 102 in the status area 100 and to the left of the editing area 86 appears a narrow dark hint field 107 with a directional arrow 103 in the processing series 88 pointing to the left, indicating that with the left directional key 52 the first control size also back to the editing area 86 is rollable, if the user still wants to make a change in the type of heating. In the preview area 92 was like in 7 to see is the hint "options" rolled, which says that additional control variables in the ad 46 can be called, in the present case by means of the time key 68 Time control variables such as duration, start time, end and short-term alarm clock or according to a modified embodiment with a Zusatzsteuergrößen- or options key, not shown here right row of keys between the right directional key 54 and the start button 70 Furthermore, an additional group of additional control variables z. B. when using a Speisethermometers the core temperature at which the oven should shut down. However, in modification of the In the embodiment shown, the entry "options" is preferably left out and the preview area is left empty, since this is not a control variable but an indication and thus the uniformity of the system, which is particularly important for simple operability, is broken via the activation of the entry "Options" in the display to control the additional control group of sizes and thus to call it.

The 8th and 9 show other examples of setting using a slightly different embodiment of the operating device, not shown here with a modified Bedieneinereihe having an additional Schnellaufheiz button right of the navigation device. The same reference numbers are used here for the same parts as in the 1 to 3 , 8th shows the representation in the display 46 after pressing the time key 68 , Preceded, as is clear from the entries of the ad 46 In this case, after switching on a selection of the preselected program group "Automatic programs" by pressing the corresponding program group key 60 , Subsequently, by means of the turntable 50 the program "squid rings, cut and deep frozen" as, in the present figures, not shown, blocked two-line entry in the processing area 86 rolled.

Continue by pressing the right arrow key 76 the next parameter, in this case the weight from the preview area 92 in the editing area 86 rolled. The weight may have been changed or left unchanged by turning the turntable. By pressing on the in 2 If there is no quick-heat button on the right side of the navigation device, then this single additional control variable has been set additionally or this function has been selected, the top right corner of the status row by the shaft symbol 104 is documented. Then by pressing the time button 68 the time functions are called, which contains several parameters such as timer or short-term alarm, start time, finished time and duration. The program information "squid rings" and the weight parameter value "0.8 kg" have been moved upwards in the status series with the various adjustment steps 102 moved, whereby the program name was abbreviated. The first parameter "Timer: 0 min" (short-term alarm clock) now in the editing area after calling the time functions is presumably not needed and you can use the arrow 96 in the preview area 92 indicated by pressing the direction button 54 to the now in the preview area 92 standing parameter "start time" continue, causing this parameter in the editing area 86 is moved to the left, which is not shown here. Subsequently, by turning the turntable 50 a start time can be set. Duration and finish time are not set in this case, since they are then specified by the program automatic. The control variable "Duration" is not displayed and the control variable "Finished time" expires as soon as the start time is set.

9 shows the representation in the display 46 after pressing the on-off button 56 and then the program group preselection key 58 , "Heating programs" and selecting the control size or the program "Upper / lower heat spec." and further change or confirm a temperature setting to "200 ° C" and press the time key 68 to call the timing variable group. The timing variables displace all previously in the processing series 88 standing entries in the status series. In this conventional program, there is no predetermined running time, so that you can now set either the timer or short-term alarm clock and / or continue and by pressing the right arrow key or several times 54 The next control variables "Start Time" and / or "End" and / or "Duration" can be controlled and set up and then the program can be started.You can combine the duration with a start time setting or end time setting At these time setting parameters, the unit of measure "min" occurs several times, so that it not only suffices for marking and that further terms such as "timer" or "start time" unambiguously accompany the value of the parameter. In the control size preview, the non-meaningful dimension "min" and in this case also the value "0", from which the setting is made, are suppressed in order to increase the clarity.

The 10 and 11 show the representations in the display after the start, where the clear distinction from the adjustment phase, the division of the display is strikingly different. Instead of the previous editing area and the preview area, there is now a large two-line continuous display and adjustment panel 105 same height over the entire width of the display 46 present in which the selected program and the main parameter, in this case the selected or confirmed temperature are displayed in two lines, with the temperature being controlled and changeable as the first parameter, followed by the circle-arrow symbol behind it 106 indicates that unlike the adjustment phase is not animated, since it does not ask for a change, but only to show the changeability. Between the program and the temperature is an arrow 96 pointing to the left to indicate that with the directional key 52 could also be moved to a renewed program selection. In the case of 10 and 11 was in the status series the symbol 104 for the set rapid heating from the setting according to 9 respectively. 8th accepted. To the left is the bell-shaped timer symbol 108 , because in these cases, a short-term alarm clock has been set, the user z. B. calls to see if the dish is ready or requires any intermediate treatment. In addition to the time of day displayed in the status row on the left-hand side 109 is a progress bar 110 This shows how much has elapsed from the runtime set with the time functions. Right next to it contains the status series 102 a work phase indication 112 in plain text, in the present case "heating up".

Also 11 shows in principle similar representations in the display after the start, but relates to an automatic program, in which not a working temperature, but the weight of the main parameters and permanently controlled in the working mode and at any time remains changeable. A directional arrow 116 right outside next to the main parameter indicates that also other parameters can be controlled and changed again. In the status row appears next to the progress bar 110 a time indication 114 "Finished in 0:42 h." The large display panel 105 is like the editing area 86 framed with dark signs on a light background.

The 12 to 16 show a different type of representations of various operating conditions on a arranged in the control panel of a cooker screen display 546 according to another embodiment of the operating device. Their control row, not shown, agrees with the control panel 28 the embodiment according to the 1 to 3 match. The content of the ad 546 is designed entirely with dark characters on a light background and has a lower width across the width of the display 546 continuous adjustment range 512 with three horizontal rows for entries, namely a top change preview row 514 , a lower change preview series 516 and an intermediate processing series 518 , which are each formed in a single line in this case, but in individual cases may be two lines in particular space requirements of an entry. Above it is above a hyphen 520 a status area with a one-line status row 522 in which left the time 524 is available as long as help information is not called in the status series. The in 18 displayed content appears after turning on the oven and pressing the program group preset button 60 , which calls up a program group with automatic programs that automatically set the heating modes and the working time according to specifications such as type, weight and desired final state of the food. Left in the adjustment area 512 stand on top of each other three of the work programs contained in this program group as a first control variable, which in the processing series 518 standing work program "Meat" by a marker 526 is highlighted in the form of a respective frame length adapted framing. In the change preview series 514 and 516 above and below are other programs of this program group or list, by turning the turntable 50 in the mark 526 are rollable. Right next to the work program is in a control size preview area 528 the processing series 518 as the next entries of the other control variables or parameters, a "type of meat" and a weight which are proposed for the marked program by the operating device, in the present case, the selected one, in the marking 526 standing program "meat" confirmed by the user by pressing the directional key 54 navigate to the right and the marker 526 in the processing series 518 on the behind entry of the kind of meat "pig" pushes on. The previously indicated not selected programs "fish" and "cake" disappear and it becomes above and below the marking 526 alternatively selectable meat type entries. Then the user has the meat type by means of the turntable 50 changed to "cattle", as in 13 you can see. Above and below the mark 526 are now the alternative selectable meat type entries "pig" and "poultry".

The user then pushed with the right direction button 54 , as in 14 you can see the mark 526 to the weight preset by the operator as an average, with the alternative types of meat from the change preview series 514 and 516 disappeared and over and under the mark 526 other selectable weights were displayed. These are just the next values of a larger list of adjustable values, which also applies to the type of meat and the work programs. The entries are all self-explanatory by z. B. in the processing series next to the actual value, the unit of measurement such as C ° or rpm are specified. The units are in the preview rows 314 and 316 suppressed, which makes the overall presentation clearer. In the present case, the user has like 14 and 15 visible, by means of the turntable 50 set a higher weight and then with the direction button 54 the next control variable called "Gargrad" is called, by then in the display 546 was not visible, but their presence by an arrow 530 at the right end of the processing series 518 was indicated. The mark 526 stays in the right end area of the processing series 518 stand and the in the ad 246 and the mark 526 scrolled entry "through" the further control size leaves the other entries to the left flow, leaving the work program "meat" left out and into the status line 522 flows. At the right end of the processing series 518 stands like in 15 you can not see an arrow anymore, which means there is no further tax code. For this, a left-pointing arrow is now on the left end 531 shown, which indicates that with the left directional key 54 also the first control variable "food" with the entry "meat" could be redone. How out 16 As can be seen, the user has changed the entry "by" to the entry "medium", wherein a parameter entry "raw", not shown in the present drawings, first in the upper preview row 514 stand was rolled out of the ad. Then he has the program sequence by pressing the start-pause button 70 started, whereupon the display 546 , as in 16 shows a somewhat different construction to indicate that the device is in operation. It also works with a color inversion, which emphasizes this condition even more clearly. At the right end of the status series 522 is now, warm the program is finished. Until the start there was after the confirmation of a program ( 13 ) How long the program in each case runs under average assumptions on the type of meat, weight and degree of cooking, this duration then being adapted to the other settings.

As 16 will be shown in the ad 46 During operation, all selected entries are displayed. In this case, the main parameter, namely the weight, is not exposed, but a parameter that is believed to be most likely to be subsequently changed by the user in use. This parameter is then permanently activated during operation, which is indicated by the marking 532 is indicated and can at any time by turning the turntable 50 be changed. However, deviating from this with automatic programs, it may make sense to not change anything after the start of the program, but to allow only a cancellation. All controls can be activated by pressing the lock button 66 be made ineffective to avoid accidental misalignment. This status is then indicated in the display by a key symbol in the status series and can be changed by pressing the lock key again 66 be undone.

In the 17 partially shown washing machine 212 has a front door 220 a control panel 222 with a division into a left detergent drawer 223 and a right panel 225 , The latter is divided into an upper display area 224 , which in the middle of the front an ad 246 has a lower operating range 226 the laterally offset below the display 246 in the middle between the drawer 223 and the right outside a horizontal control row 228 in principle, as in the case of the stove according to the 1 to 3 is constructed with a central navigation device 248 with a turntable 250 and left outside of an on-off button 256 and right outside a start-pause button 270 , Right and left of the turntable 250 are directional buttons 252 and 254 arranged. The on-off button 256 functions simultaneously as a program group preselection key and, when switched on, calls a work program group of conventional textile type programs, with the main parameter working temperature. There is also a program group preselection button 257 arranged to call up pollution type programs e.g. For example, "sports underwear" or "outdoor", with the main parameter pollution type, which are different from the approach of the Textilart programs, and further to the right a program group preselection key 259 for calling individually set and stored by the user work programs. Right of the navigation device 248 are still a setup button 260 for calling up and removing programs for basic settings and an information key 262 arranged to call and remove help texts. All buttons of the control panel 28 are rectangular horizontally stretched arranged as two keyboard groups, with non-latching short-stroke keys that feel something about the front face of the control panel 222 rise. Above the left row of keys, with a small gap 274 to the left direction button 252 connects is a lightbar 278 arranged, consisting of individual, low, in each case over the entire button width extending light indicators that light up when the corresponding button was pressed. Likewise, it owns with a small distance 276 to the right direction button 254 subsequent right button row such a light bar 278 , The light color is blue. The navigation device 246 owns on the directional buttons 252 and 254 light arrows 253 and 255 and a turntable 250 surrounding light ring 284 that light up when using the navigation device 246 Settings can be made. The function of the light indicators of the left and right row of keys and the navigation device are therefore different, which can also be indicated by a different light color. Furthermore, the light arrows work 253 and 255 together with the dialogue control and show by their illumination in which directions a setting is possible.

The content of in 18 display shown in detail 246 the washing machine of 17 is designed entirely with dark characters on a light background and has a lower, across the width of the ad 246 continuous adjustment range 312 with three horizontal rows for entries, namely a top change preview row 314 , a lower one Änder preview series 316 and an intermediate processing series 318 , which are each formed in a single line in this case, but in some cases can also be used in two lines with particular space requirements of an entry. Above is a horizontal hyphen 320 across the entire width of the ad 246 a status area 321 with a one-line status series 322 in the left the time 324 does not stand help information in the status series 322 is called. The in 18 displayed content appears when you turn on the washing machine by pressing the on-off button 256 , which calls up a program group of conventional washing programs by textile type. Left in the adjustment area 312 stand on top of each other three of the work programs contained in this program group, which in the processing series 318 standing work program by a marker 326 is highlighted in the form of a respective frame length adapted framing. In the change preview series 314 and 316 above and below are other programs by turning the turntable 250 in the mark 326 are rollable. Right next to the work program are in a control size preview area 328 the processing series 318 as next entries of the other control variables or parameters a washing temperature and a spin speed, which are proposed for the marked program by the operating device. In the present case, the selected, in the mark 326 standing program "Coloreds" thereby confirming that the user by pressing the directional key 254 navigate to the right and the marker in the editing row 318 moves on to the entry behind the proposed temperature. This will disappear the previously displayed non-selected programs and it will be in the change preview rows 314 and 316 above and below the mark 326 alternatively selectable temperature entries shown as in 19 you can see. In the present case, the user rolled a higher temperature from the change preview series 316 in the mark 326 as in 20 can be seen and then navigated to the right the marker 326 to the proposed spin speed on. The alternative temperature values from the change preview series disappeared as well 316 . 318 , Above and below the mark other selectable speed entries are displayed. These are only the next values of a larger list of adjustable values, which also applies to the temperatures and the work programs. The entries are all self-explanatory by z. B. in the processing series next to the actual value, the unit of measurement such as C ° or rpm are specified. The units are in the preview rows 314 and 316 suppressed, which makes the overall presentation clearer.

In the present case, the user has like 21 seen, a higher spin speed selected and confirmed by pressing the direction button 254 called up the next control variable, which was not seen in the ad until then, but whose presence is indicated by an arrow 330 at the right end of the processing series 318 was indicated. The mark 326 stays in the right end area of the processing series 318 stand and the in the ad 246 and the mark 326 The entry "Pre-wash on" of the further control variable causes the other entries to flow to the left, with the work program "Color wash" left out and into the status line 322 flows. At the end of the processing row is like in 21 you can not see an arrow anymore, which means there is no further tax code. This is now indicated at the left end of the processing series 318 a left arrow 331 , who points out that also the repressed control variable "work programs" with the left directional key is again controllable, ie back into the processing row holbar.If the user agrees with the suggestion "Prewash on", he can program the program by pressing the start -Pause button 270 start, prompting the ad 246 , as in 22 shows a slightly different structure to indicate that the device is in operation. Deviating from the illustration in 22 could also be worked with a color inversion, which indicates this condition even more clearly. At the right end of the status series 322 is when the program is finished. Until the start there was the choice of a program ( 18 ) how long the respective program is running. In the present schematic representations, the same duration has always been indicated for the sake of simplification in the further work steps or operating steps, but this will change practically in dependence on the selected temperature and spin speed.

As 22 will be shown in the ad 246 During operation, all selected entries are displayed. The main parameter is in the adjustment range 312 shown exposed and permanently activated during operation, what the mark 332 is indicated and can at any time by turning the turntable 250 be changed. By a lock button, not shown, the controls can also be made ineffective to avoid accidental adjustment.

At the in 23 illustrated modified control element series 428 are in a modification of the washing machine according to 17 next to a turntable 450 , a navigation device 448 right and left directional buttons 452 and 454 arranged. In addition to an on-off button 456 on the left outside are to the right a program group preselection key 457 for calling conventional textile programs with the washing temperature as the main one parameter, a program group preselection key 458 for calling a program group of pollution type programs and a program group preset key 459 for calling user-set and stored work programs. To the right direction button 454 Close an additional control key to the right 459 for calling up a group of additional control parameters or parameters, a set-up key 460 and an information button 462 as well as a start-pause button 470 at. The in the presentation of the 23 under the control panel 28 Arranged arrows and numbers in circles indicate that the device is first turned on with the left most extreme control and secondly set with the following controls and thirdly started with the right most extreme control. The keys, which are arranged in a row with a slight projection, are shaped and lined up in such a way that the transitions between them are easily felt with the fingers, with each one between the directional keys 452 and 454 and the adjacent keys 449 and 459 a noticeably larger but still small gap 476 and 476 in the series. All buttons of the control panel 428 are rectangular horizontally stretched arranged as two keyboard groups, with non-latching short-stroke keys that rise tangibly something over the front surface of the control panel, not shown. Above the left row of keys is a light bar 478 arranged, consisting of individual, low, in each case over the entire button width extending light indicators that light up when the corresponding button was pressed. Likewise, the right row of keys has such a light bar 478 , The light color is blue. The navigation device 446 owns on the directional buttons 452 and 454 light arrows 453 and 455 and a turntable 450 surrounding light ring 484 that light up when using the navigation device 448 Settings can be made. The function of the light indicators of the left and right row of keys and the navigation device are therefore different, which can also be indicated by a different light color. Furthermore, the light arrows work 453 and 455 together with the dialogue control and show by their illumination in which directions a setting is possible.

The control device to which this control row 447 to 23 owned, owns an ad 446 , which is designed entirely with dark characters on a light background and their content based on some examples in the 24 to 28 is explained. The ad 446 has a lower over its entire width continuous adjustment range 412 with three horizontal rows for entries, namely an upper change preview series 414 , a lower change preview series 416 and intermediate processing series 418 , which are each formed in a single line in this case, but in some cases can also be used in two lines with particular space requirements of an entry. Above is a horizontal hyphen 420 a status area 421 with a one-line status series 422 in the left the time 424 is, as long as not a help information in the status series 422 is called. The in 24 display content displayed in this case appears after switching on by pressing the on-off button 456 and then pressing the program group key 457 or P with which the group of conventional textile type work programs with the main parameter temperature is called. Left in the adjustment area 412 stand on top of each other three of the work programs contained in this program group, which in the processing series 518 standing work program "color laundry" by a mark 526 is highlighted in the form of a respective frame length adapted framing. In the change preview series 514 and 516 above and below are other work programs, by turning the turntable 450 in the mark 426 are rollable. Right next to the work program are in a control size preview area 427 the processing series 418 as next entries of the other control variables or parameters a washing temperature and a spin speed, which are proposed for the marked program by the operating device. In the present case, the selected, in the mark 426 The program "Coloreds" is confirmed by the user continuing to navigate to the right by pressing the right arrow key to the next entry of the proposed temperature, with all entries in the processing series 418 flow to the left and the temperature in the fixed processing area of the frame-like marking 426 is formed in the left end area of the processing series 418 goes. To the left of this, at the left end of the processing row, is a directional arrow pointing to the left 431 shown, indicating that the previously edited and now in the status series 422 flowed control variable "color laundry" with the left directional key 452 is again controllable. Above and below the temperature proposed by the operating device for the selected program 60 ° Celsius are in the preview rows 414 and 416 in each case the next below and above selectable temperature, where in the preview rows 414 and 416 For clarity, the specification of the dimension degrees Celsius is suppressed. The in the preview series 414 and 416 standing and more in the ad 446 Scrollable temperature entries can now be moved up and down by turning the turntable 450 be selected to the right or left. Then you can press the right direction button again 454 moved to the right and the control variable or the parameter "spin speed" in the processing area or the mark 426 at the left end of the processing series 418 pulled and even be changed with the turntable. In 25 the control variable preview range contains only the control variable spin speed, since in this case no further adjustable control variable follows this program call. The control color "Colored laundry" has moved into the status series when controlling the temperature control variable to indicate what has already been set.The status row contains an indication of the working time of this program at its right end and the time when the program was pressed when the start button was pressed finished, which is not shown here.

In the embodiment according to the 24 to 28 is different from the embodiment according to the 18 to 22 , the control quantity "prewash on / off" is not assigned to the main control variables appearing after calling up a preselection program group, but to an additional control variable group which is assigned by means of the right of the right directional key 454 arranged additional control variables button 461 is called, whereupon the in 26 displayed content appears and the contents of the editing series 418 displaced into the status series. The previously made settings will continue to be displayed by moving the corresponding selected or left entries to the status row. Again, in the case of additional control variables, the controls and changes, as described above with reference to 24 and 25 described made. Is there enough space in the status series? 422 It is no longer possible to record and display all the parameter entries that have flown out of the processing row to the left, showing them these entries by alternately representing part of them every three to five seconds. Alternatively, the status series can also be formed in two lines or the entries to be displayed there can be transformed into symbols which require less space. In order not to disturb the symbols, which are preferably placed in a right-justified manner in the status series, or to make them not too small and poorly visible, the dividing line can in each case be located in their area 420 be interrupted. By pressing the additional control key again 561 the old state is restored before their pressures, see abge that the controlled additional control variables are displayed even after the shutdown by means of the additional control variables button in the status row at least as symbols. In the present case, the user first changed the first additional control variable "prewash" from "off" to "on" ( 26 ), then control the "pollution" control variable and leave it "easy" ( 27 ) and then in this schematic. Example last control variable "final spin" of this group activated and left "on" ( 28 ). The control size preview area is now empty. If it now starts the program sequence directly or after switching back to the pre-selection group, then the division of the display contents after the start is a different one not shown here, similar to the one in FIG 22 which shows that the device is in operation. Even after the start, the settings of all control variables activated in the operating phase are displayed. The additional control variable group preferably contains only control variables or parameters with two values, eg. Yes / no or on / off. The control variables which can be set by the user in the normal operating phase for a specific work program are all contained in the two control variable groups which can be called up by means of one of the program group preselection keys and then the additional control variable key. For other devices, some of the control variables that can be set in the operating phase are still grouped in a time control group, which can be called up for adjustment via a time button. Single control size keys, which only set a control value or call up for setting in the display, should be avoided as far as possible in order to keep the setting system as uniform as possible and to keep the number of keys low. It should be achieved with a minimum number of controls one, for a quick, easy operation overall optimal combination of operation via controls and dialogue with the display.

The reference numbers above 500 be prominent in the 12 to 16 used.

The in the 29 and 30 show a section of a control panel 622 a dishwasher with an operating area 626 on the one control panel 628 is arranged. This has in its center a four-way navigation device 648 with a central rocker switch 650 which is tiltable about a horizontal axis from a neutral position in two directions. The rocker switch 650 forms a change device in the form of a two-way vertical adjusting device, with the entries of the control variables shown in a display are vertically scrollable or blätterbar. As a horizontal adjusting device serve a left directional key 652 and a right directional button 654 , the left and right of the rocker switch 650 are arranged approximately along the horizontal tilt axis. This is followed by a horizontal row of lower horizontal stretched substantially gapless adjacent keys to the right and left, for easy removal of the navigation device 648 at a small distance 674 and 676 from the directional buttons 652 and 654 kick off. All buttons of the control panel 628 Rectangles are horizontally stretched horizontally as two keyboard groups, with non-latching short-stroke keys that feel something over the front surface 672 the control panel 622 rise. Above the left row of keys, with a small gap 674 to the left Rich PREPARATION button 652 connects is a lightbar 678 arranged, consisting of individual, low, in each case over the entire button width extending light indicators that light up when the corresponding button was pressed. Likewise, it owns with a small distance 676 to the right direction button 654 subsequent right button row such a light bar 678 , The light color is blue. The navigation device 646 owns on the directional buttons 652 and 654 left and right-facing light arrows 653 and 655 and one the rocker switch 650 surrounding light ring 684 that light up when using the navigation device 646 Settings can be made. The rocker switch 650 is cylindrical as seen from the front and bounces slightly over the rows of keys and the directional keys 652 and 654 before and has a concave slightly inwardly curved front surface with two, pointing up and down direction arrows 653 and 655 , It corresponds in diameter and in the curvature of its front face a turntable of another device a series creatively matched to each other different devices such as ovens, washing machines or dishwashers, but the front surface of the turntable is curved outward. Such a rocker switch is preferably used in devices with smaller adjustment ranges.
