The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention can be taken from the dependent claims.

The invention is based on a domestic appliance display device having at least one display unit and at least one control unit which has at least one data collection.

It is proposed that the data collection has at least one dataset which is provided to display at least one part of a graphic displayed by the display unit in an operating mode changed in terms of at least one display variable. By "provided" is meant in particular specially equipped and / or designed and / or programmed A "control unit" is to be understood in particular as a unit having a computing unit or processor unit and / or a memory unit. In particular, at least the data collection is stored in the memory unit. A "graphic" is in particular at least an image, a letter, a symbol, an image, a visualization and / or an outline.Particularly advantageously, the graphic is assigned to an object, which is in particular a cooking zone in the change of the representation of the graphic advantageously maintained intended to display the entire graphic changed in terms of at least one representation size. A "representation size" of a part of a graphic should be understood to mean, in particular, an extension length of the part in one of its directions of extent Value of a representation size is displayed, which differs from a value of the representation size in another representation of the part. With an embodiment according to the invention, an easily comprehensible display of information can be achieved.

Preferably, the amount of data is intended to be a symbol of a selected one

Highlight cooking zone. As a result, a high level of operating comfort can be achieved. Particularly advantageous is the amount of data provided to enlarge the symbol, whereby a very simple operation can be achieved. In particular, the icon will be flashing, further highlighting the icon.

Furthermore, it is proposed that the amount of data is intended to represent at least one part of a graphic displayed by the display unit in an operating mode in a distorted manner. The term "distorted representation" of a part of a graphic should in particular mean that at least one proportion of the part is shown altered in a comparison to another representation of the part Part. As a result, a particularly high flexibility in the representation of the graph can be achieved.

Advantageously, the amount of data is provided to represent at least one of the display unit in an operating mode displayed position of two symbols changed relative to each other. In particular, a position of two symbols relative to one another is changed by changing a distance of the two displayed symbols or by changing a direction of a connecting line of the two center points of the symbols. A "distance" of a first and a second symbol is to be understood in particular to mean the shortest connecting distance of a point of the first symbol to a point of the second symbol, whereby a compact display of the symbols can be achieved. The data collection has at least the amount of data which in particular represents at least a quantity of image data, which in particular is a graphic. It should be understood, in particular, that there is a device which can display the graphic by means of the image data set Graphics that differ in terms of at least one representation size of a portion of the graph, so that can be easily displayed a graph with a changed display size, while a computational effort can be avoided.

Alternatively or additionally, the data collection may have at least one amount of data corresponding to at least one software. In particular, at least one program is to be understood as "software." In particular, a program is a collection of instructions that are intended to be executed by at least one processor or a computing unit, and which in particular are combined into one unit and The task may be a control of the display unit, In a preferred embodiment of the invention, at least a portion of the data set is a presentation size change program. which is intended to allow a representation of a displayed graphic with at least one changed presentation size. This allows a flexible variability of presentation sizes can be achieved and it can be saved storage capacity. For example, it is proposed that at least part of the data set is a distortion program. In particular, a "distortion program" is to be understood as meaning a program which is intended to enable a display of a displayed graphic, which may be represented by an image data set, with at least one changed quotient of two presentation variables Representation of a graph in an output by the display unit for a comparison in a modified representation in a final size by the display unit, a representation of the graph in sizes, which are between the starting and the final size possible, thereby enabling the operator to perceive the resizing of the graph , Advantageously, the graphic has at least one cooking zone symbol. This can be an easy understandability of a display can be achieved. Preferably, at least one symbol is integrated in the cooking zone symbol, whereby displayed information can be assigned to a user in a particularly intuitive way.

In addition, it is proposed that the graph represents at least one hob. In this way, a high degree of clarity can be achieved.

In a preferred embodiment of the invention, the amount of data is intended to increase at least one of at least two symbols displayed by the display unit in an operating mode and to reduce the size of at least one other. Thus, despite a constant display area with a high clarity, a symbol can be displayed very easily detected.

Furthermore, a display method is proposed in which at least one part of a graphic displayed by a display unit in an operating mode is displayed differently in terms of at least one display variable. According to the invention, an easily comprehensible information representation can be achieved.

Further advantages emerge from the following description of the drawing. In the drawings, embodiments of the invention are shown.

FIG. 1 shows a plan view of a domestic appliance designed as a hob 38. The cooking field 38 has cooking zones 28 to 36 and a domestic appliance display device 40 with a display unit 10, an operating unit 42 and a control unit 12. The control unit 12 has a data collection 14 with a data set 16 which is provided to display at least one circular graphic 18 displayed by the display unit 10 in an operating mode with respect to at least one display variable 20 (FIG. 2).

The display unit 10 has a rectangular shape and is constituted by two hundred pixels in its longitudinal direction by one hundred and twenty-eight pixels in its width direction, dispense with the representation of the individual pixels. The display unit 10 is intended to reproduce representations of the cooktop 38, with the cooking zones 28-36 generally being represented by the graphic 18 and circular graphics 22, 24, 26, 27. In Figure 2, the graphs 18, 22, 24, 26, 27 are consistent with figures 19, 21, 146, 148, 150 showing the cooking zones 28 to 36 in an inactive state. Representations of the graphics 18, 22, 24, 26, 27, such. The illustrations 19, 21, 146, 148, 150 are included in the data set 16 in the form of image data. The illustration 19 corresponding to a representation of the graphic 18 is a symbol with a diameter 56 which corresponds to the representation variable 20. If an operator selects the cooking zone 28 by means of a touch element 54 (FIG. 2) of the operating unit 42, the graphic 18 is changed in such a way that the cooking zone 28 is represented by a circular image 58 with a larger diameter 60 compared to the diameter 56 symbolizes becomes (Figure 3), whereby the symbol of the cooking zone 28 is highlighted. Since the display unit 10 has a display surface which is invariable in size, the remaining cooking zones 30 to 36 are now represented by circular figures 62 to 68 of reduced diameter compared to the pictures 21, 146, 148, 150 (FIG. 2) , For this purpose, the representation of the hob 38 with the images 58 and 62 to 68 in the form of image data is stored in the data set 16 of the display unit 10 in Figure 3.

FIG. 2 shows a graph 70, which is formed by the graphics 18, 22, 24, 26, 27 and represents the hob 38. 3, the illustrations 58, 62, 64, 66, 68 together form a representation of the graphic 70, which likewise symbolizes the hob 38. Due to the selection of the cooking zone 28 by the operator, a representation changes from the graphic 70 from that shown in FIG. 2 to the representation depicted in FIG. 3, which is given by a symbol 72 and a distortion of the representation of FIG Graphic 70 in FIG. 2. Thus, for example, the ratio of a length 74 to a width 76 of the graphic 70 in FIG. 2 differs from a ratio of a length 78 to a width 80 of the graphic 70 in FIG. 3. As a result of this distortion, space is created on the display surface of the display unit 10 Display of a thermometer icon 84 is used. The thermometer icon 84 symbolizes that the home appliance display 40 is in a temperature selection mode.

In FIG. 2, a symbol 120 of the cooking zone 30 is represented by the illustration 21 and a symbol 122 of the cooking zone 34 by the illustration 148. Both symbols 120, 122 have a circle as an outline. The symbols 120, 122 are spaced apart from each other by a distance of 124. Following selection by the operator of the cooking zone 28, the symbols 120, 122 are represented by Figures 62 and 66 (Figure 3), which are reductions of Figures 21 and 148, and as well as these are stored as image data in the data set 16. Since the distance 126 of the images 62, 66 is greater than the distance 124, the display unit 10, after selecting the cooking zone 28, changes the position of the symbols 120, 122 relative to one another.

Further, the operator is prompted by the display of a touch element icon 86, which is integrated into the image 58, which has a cooking zone symbol, to set a power level for the cooking zone 28 by means of a symbolized touch element 82 of the control unit 42. If the operator follows this request, then a figure indicating the selected power level is integrated into the map 58, and in addition, a color of a circular area 59 of the image 58 symbolizing the cooking zone 28 is changed, forming an image 88 (FIG. 4). If no further adjustment is made, the image 88 is automatically reduced to the extent of the image 19 (FIG. 2) after a settable time span, which is, for example, five seconds, which results in an image 92 (FIG. 5). Optionally, in an active state of the cooking zone 28, this can also be symbolized by an enlarged illustration 94 in comparison to FIG. 19 (FIG. 6). In both variants, the touch element icon 86 is replaced by a bar icon 87, indicating that a selection of a power level has been made.

Furthermore, by a time-selection touch element 96 of the operating unit 42, a time preset mode for the last activated cooking zone 28 can be selected. If an operator actuates the time-selection touch element 96, an image 98 representing the cooking zone 28 is enlarged in comparison to the image 19 (FIG. 2). By means of the touch element 82, the operator can set a cooking time 100, which is displayed integrated into the cooking zone symbol shown in FIG. 98 (FIG. 7). Optionally, after that, the cooking zones 28 to 36 can again be symbolized in an output variable shown in FIG. 2 (FIG. 8).

In an analogous way, a power level and a cooking time can be selected for the cooking zone 36 (FIGS. 9 to 16). After a selection (FIG. 9) of a power level of the cooking zone 36, this is symbolized by an image 102 (FIG. 10) that is enlarged, colored and displays the selected power level in comparison to FIG. 150. In this case, the cooking zone 28 is represented by a reduced and colored image 110 compared to FIG. 19 (FIG. 2), in which the selected power level of the cooking zone 28 and the cooking time set for the cooking level are displayed. If, due to the size of a cookware placed on the cooking zone 36, a cooking zone extension 104 (FIG. 1) is automatically switched on by the hob 38, this is indicated by a complete coloration of an image 106 symbolizing the cooking zone 36 (FIG. 11). If the cooking zone extension 104 is inactive, then an outer area 108 of the image 102 symbolizing the cooking zone 36 remains uninfluenced both in a selected and in an unselected state of the cooking zone 36 (FIGS. 12 and 13). Figure 14 shows the graph 27 for a selection of a cooking time. FIG. 15 is an illustration of the hob 38, wherein the cooking zone 36 after selecting the cooking time is in an unselected state. FIG. 16 is an alternative illustration of the cooktop 38 in this state.

If one of the cooking zones 28 to 36, such. As the cooking zone 30, and turned off after a certain period of operation again, so that this cooking zone 30 has a residual heat, the residual heat is represented by a coloring of this cooking zone 30 symbolizing Figure 1 12 (Figure 17). Optionally, the residual heat can be additionally illustrated by a letter integrated into a cooking element symbolizing the cooking zone 30 (FIG. 18).

The cooking zone 34 (FIG. 1) has a booster function, which can be activated by means of a touch element 16 of the operating unit 42. If an operator makes the activation, then the cooking zone 34 is represented by an enlarged image 118 (FIG. 19) in comparison with FIG. 148 (FIG. 2), and a representation of the hob 38 by the display unit 10 is distorted, leaving room for one Boost symbol 119 appears on the display area. After the cooking zone 34 has reached its maximum temperature, as described for the cooking zone 28, a power level can also be set for the cooking zone 34 (FIGS. 20 and 21), which is analogous to the process described by FIGS. 4 and 5.

Further, the cooking zone 34 may be used in a fryer sensor operating mode with a pyrometer 39 extended from the hob 38 (see FIG. 1). If the frying sensor operating mode is selected by means of a touch element 128, this is represented by a pan symbol 130, which is integrated into an image 132 symbolizing the cooking zone 34 (FIG. 22). Further, the operator is prompted by three different bar symbols 134 integrated into the image 132 to select one of three possible power levels. A selection of the first power level by means of the touch element 82 is indicated by a coloring of the first bar symbol 134. Accordingly, a selection of the second and third power levels is displayed. After selecting a power level, the cooking zone 34 is again displayed in its output, with the selected power level represented by the bar symbols 134 (Figure 23).

The cooking zone 34 is also programmable. If such a programming is carried out by means of the operating unit 42, this is indicated by a symbol 136, which in an illustration 138 symbolizing the cooking zone 34 is shown (FIG. 24). At the same time, the display unit 10 forms an operating menu 140, from which different, time-dependent performance characteristics are selectable, which are particularly suitable for certain dishes. Due to the operating menu 140 shown, the graphic 70 (see FIG. 2), which symbolizes the hob 38, is distorted and reduced in a figure 142 by the display unit 10 (FIG. 24).

FIGS. 25 to 27 show an alternative embodiment of a domestic appliance display device. Substantially identical components, features and functions are in principle numbered with the same reference numerals. However, to distinguish between the embodiments, the letters "a" are added to the reference numerals of the embodiment in Figures 25 to 27. The following description is limited essentially to the differences from the embodiment in Figures 1 to 24, with respect to components remaining the same and functions can be referred to the description of the embodiment in Figures 1 to 24.

FIG. 25 shows a hob 38a with a domestic appliance display device 40a, which has a control unit 12a with a data set 16a. A part of the data amount 16a is a display size changing program including a distortion program. In addition, the control unit 12a comprises a processor unit 152.

In FIG. 26, a display unit 10a depicts a representation of the cooktop 38a. A cooking zone 28a is represented by a representation of a graphic 18a shown in FIG. 19a with a representation size 20a which corresponds to a diameter 56a. If an operator selects the cooking zone 28a, the display size changing program causes an enlargement of the representation of the graphic 18a in FIG. 26 in that the processor unit 152 calculates an enlargement of the image 19a by means of data representing the image 19a, which is represented by the display unit 10a in a figure 58a (Figure 27).

In FIG. 26, the hob 38a is symbolized by a representation of a graphic 70a. Upon selection of the cooking zone 28a by the operator, the processor unit 152 calculates, based on the representation of the graph 70a, by means of the distortion program a distortion of this representation, which is shown in Figure 27 by a symbol 72a of the display unit 10a.
