[0035] In the figures, elements that are identical or have the same function have been provided with the same reference characters unless otherwise stated.

[0036] FIG. 1 shows a schematic perspective view of an embodiment of a household appliance 1. The household appliance 1 is preferably a water-using household appliance. In particular, the household appliance 1 is a household dishwasher. However, the household appliance 1 may also be an oven, a washing machine, a tumble dryer, a freezer, a refrigerator or the like. Subsequently it will be assumed, however, that the household appliance 1 is a household dishwasher.

[0037] The household appliance 1 comprises a receiving region 2, which can be closed off by a door 3, in particular in a watertight manner. A sealing facility may be provided for this purpose between the door 3 and the receiving region 2. The receiving region 2 is in particular a dishwasher cavity of the household appliance 1, or may be referred to as such. The receiving region 2 is preferably cuboid in shape. The receiving region 2 may be arranged in a housing of the household appliance 1. The receiving region 2 and the door 3 may form a washing chamber 4 for washing items to be washed.

[0038] The door 3 is shown in its open position in FIG. 1. The door 3 can be closed or opened by pivoting about a pivot axis 5 provided on a lower end of the door 3. A loading opening 6 of the receiving region 2 can be closed or opened with the aid of the door 3. The receiving region 2 has a base 7, a ceiling 8 arranged opposite the base 7, a rear wall 9 arranged opposite the closed door 3, and two side walls 10, 11 arranged opposite one another. The base 7, the ceiling 8, the rear wall 9 and the side walls 10, 11 can be manufactured from a stainless-steel sheet, for example. Alternatively, the base 7 can be manufactured from a plastic material, for example.

[0039] The household appliance 1 also has at least one receptacle 12 to 14 for items to be washed. A number of, for instance three, receptacles 12 to 14 for items to be washed can preferably be provided, wherein the receptacle 12 for items to be washed can be a lower receptacle for items to be washed or a bottom basket, the receptacle 13 for items to be washed can be an upper receptacle for items to be washed or an upper basket, and the receptacle 14 for items to be washed can be a cutlery drawer. As additionally shown in FIG. 1, the receptacles 12 to 14 for items to be washed are arranged one above the other in the receiving region 2. Each receptacle 12 to 14 for items to be washed is optionally able to be shifted into or out of the receiving region 2. In particular, each receptacle 12 to 14 for items to be washed is able to be inserted or pushed into the receiving region 2 in an insertion direction E and extracted or pulled out from the receiving region 2 in an extraction direction A opposite to the insertion direction E.

[0040] FIG. 2 shows a schematic side view of the household appliance 1. As shown in FIG. 2, the door 3 can be brought from a closed state Z1 via any number of intermediate states Z2 into a fully open state Z3. In the intermediate state Z2, the door is referred to with the reference character 3'. In the open state Z3, the door is referred to with the reference character 3". When the door 3 is brought from the closed state Z1 into the open state Z3, the door 3 is pivoted by an opening angle α in relation to the receiving region 2. The opening angle α is defined as an angle between the door 3 and a flange that encloses the loading opening 6 of the receiving region 2. In the closed state Z1, the opening angle α is 0°; in the intermediate state Z2 shown in FIG. 2, the opening angle α is 15 to 25° for example; and in the open state Z3, the opening angle α is 90°.

[0041] FIG. 3 shows the detail view III according to FIG. 2. As shown in FIG. 3, the door 3 comprises a front side 15 facing away from the receiving region 2 and a rear side 16 facing toward the receiving region 2. Here, the front side 15 and the rear side 16 are arranged parallel to one another and positioned at a distance from one another. An upper edge 17 is provided between the front side 15 and the rear side 16. The upper edge 17 connects the front side 15 to the rear side 16. The upper edge 17 is preferably positioned perpendicular both to the front side 15 and also to the rear side 16.

[0042] The household appliance 1 comprises a control and display facility 18 provided in or at the door 3. The household appliance 1 can be controlled with the aid of the control and display facility 18, and an operating state of the household appliance can be displayed, for example. The control and display facility 18 may be or comprise for example a touchscreen. Furthermore, the control and display facility 18 may have any number of other control and display elements. For example, the control and display facility 18 may comprise switches, displays, light-emitting diodes or the like.

[0043] The control and display facility 18 comprises a first section 19 assigned to the front side 15, a second section 20 assigned to the upper edge 17, and a third section 21 assigned to the rear side 16. The first section 19 is arranged at or on the front side 15. The second section 20 is arranged at or on the upper edge 17. The third section 21 is arranged at or on the rear side 16. The control and display facility 18 consequently encloses the upper edge 17.

[0044] Optionally, one of the sections 19 to 21 may also be omitted. For example, the control and display facility 18 may be embodied without the third section 21 assigned to the rear side 16. In this case, the control and display facility 18 is arranged only at or on the front side 15 and at or on the upper edge 17. Furthermore, a control unit 22 which may be arranged inside the door 3, for example, is assigned to the control and display facility 18. Washing programs of the household appliance 1 may be stored in the control unit 22, for example.

[0045] The first section 19 of the control and display facility 18 is suitable for displaying items of information and/or enabling functions that are relevant in the closed state Z1 of the door 3. In the present context, an “item of information” may be understood to mean a symbol, a pictogram or a sequence of letters and/or numbers. An item of information displayed by the control and display facility 18 that is relevant in the closed state Z1 may be a remaining time in a washing program of the household appliance 1, for example. A “function” may be understood to mean for example the selection of various options in a washing program, such as “speed on demand” or “silence on demand”, starting or pausing the washing program or the like, for example. The function can be “enabled” by the item of information, for example a symbol displayed by the control and display facility 18, being chosen or selected by a user with the touch of a finger.

[0046] The second section 20 of the control and display facility 18 is suitable for displaying items of information and/or enabling functions that are relevant in the intermediate state Z2. Here, the relevant items of information or functions comprise the selection of the washing program and/or options of the washing program, or starting the washing program. In particular, a general control of the household appliance 1 is possible in the intermediate state Z2, as this is the most ergonomic position for the user. For example, in the intermediate state Z2 the household appliance 1 may be controlled and the washing program selected with the aid of the control and display facility 18.

[0047] The third section 21 of the control and display facility 18 is suitable for displaying items of information and/or enabling functions that are relevant in the open state Z3 of the door 3. For example, in the open state Z3 top-up reminders may be displayed with the aid of the control and display facility 18, such as when water softener salt, rinse-aid or detergent are low, for example. Furthermore, explanations such as brief instructions regarding the household appliance 1, for example, may also be displayed with the aid of the control and display facility 18.

[0048] FIG. 4 shows one embodiment of the control and display facility 18. This means that, in FIG. 4, all sections 19 to 21 of the control and display facility 18 are arranged in one plane and are not, as shown in FIG. 3, positioned in a U shape. As previously mentioned, each section 19 to 21 is assigned at least one item of information x, y, z that is only displayed by the control and display facility 18 when the door 3 is in the corresponding state Z1 to Z3. Thus, for example, the item of information x is only displayed when the door 3 is in the closed state Z1. The item of information y is accordingly only displayed when the door 3 is in the interim state Z2. By contrast, the item of information z is only displayed when the door 3 is in the open state Z3.

[0049] Furthermore, as shown in FIG. 4 on the basis of the item of information x using arrows 23, 24, it is also possible for the respective item of information x, y, z to move across the control and display facility 18 depending on the opening angle α. For example, when the door 3 is brought from the closed state Z1 into the intermediate state Z2, the item of information x moves from the first section 19 to the second section 20 of the control and display facility 18. Conversely, when the door 3 is brought from the intermediate state Z2 into the closed state Z1, the item of information x can shift again from the second section 20 back to the first section 19. When the door 3 is brought from the intermediate state Z2 into the open state Z3, the item of information x accordingly shifts from the second section 20 to the third section 21 of the control and display facility 18. Conversely, when the door 3 is brought from the open state Z3 into the intermediate state Z2, the item of information x can shift again from the third section 21 back to the second section 20.

[0050] It is therefore possible with the aid of the control and display facility 18 to display to a user only the items of information x, y, z or functionalities that are relevant for the respective opening angle α. Furthermore, printed pictograms or symbols may be dispensed with as these can be digitalized and displayed with the aid of the control and display facility 18. It is thereby possible to display to the user only the respective item of information x, y, z that is relevant at the corresponding moment in time and to link this to the opening angle α of the door 3. Thus, for example, when the door 3 is in the closed state Z1, only the remaining time, the start or pause options, and extra functions such as “speed on demand” and “silence on demand” are displayed on the first section 19 of the control and display facility 18.

[0051] When the door 3 is opened, some items of information x, y, z become irrelevant, such as “speed on demand” or “silence on demand”, for example. This is because the aforementioned functions are only switched on if the household appliance 1 is already running. Other items of information x, y, z still remain relevant when the door 3 is opened, such as the start/pause function, for example. Furthermore, there are items of information x, y, z that may be modified. The clock that displays the remaining time on the outside of the door 3 becomes a clock that displays the program duration. This simplifies the selection of the program.

[0052] The transformation of items of information x, y, z may be visualized by means of an animation to make it clearer for a user that only the relevant items of information x, y, z are in his/her field of view and the household appliance 1 is responding intelligently to his/her behavior. Information overload may be prevented because only those items of information x, y, z are displayed to the user that are appropriate for the opening angle α of the door 3. This increases the operating convenience.

[0053] Although the present invention has been described with reference to exemplary embodiments, it can be modified in numerous different ways.
