The present invention relates to a household appliance, in particular a household dishwasher.

A dishwasher comprises a washing container on which a door is hinged so that it can pivot. An operating and display device can be provided on the door, with the aid of which the dishwasher can be operated and with the aid of which information, such as, for example, the remaining running time of a washing program, can be displayed. When the door is opened, an angle at which a user can inspect the operating and display device changes.

Against this background, it is an object of the present invention to provide an improved household appliance available.

Accordingly, a household appliance, in particular a household dishwasher, is proposed with a receiving area, a door hinged on the receiving area and an operating and display device provided on the door, information displayed by the operating and display device depending on an opening angle of the door change.

Because the information displayed changes as a function of the opening angle of the door, it can be ensured that the information can always be viewed equally well for a user regardless of the opening angle.

The household appliance is preferably a household dishwasher. However, the household appliance can also be a household oven, a household washing machine, a household dryer, a household refrigerator, a household freezer or the like. The receiving area is preferably a washing compartment of the household appliance. The receiving area is preferably cuboid and comprises a floor, a ceiling arranged opposite the floor, two side walls arranged opposite one another and one arranged opposite the closed door Back wall. With the help of the door, a loading opening of the receiving area can be closed and opened. In the present case, the fact that the door has "hit" the receiving area is to be understood in particular as meaning that the door is pivotably connected to the receiving area, for example with the aid of hinges.

The opening angle is defined in particular as an angle between the door and a flange of the receiving area that extends around the loading opening of the receiving area. The operating and display device is preferably mounted on, on or in the door. The operating and display device is preferably permanently connected to the door. With the help of the control and display device, the household appliance can be operated, for example in such a way that a washing program can be selected with the help of the control and display device. Furthermore, the operating and display device is suitable for displaying information to be output by the household appliance.

In the present case, “information” can be understood to mean, for example, pictograms or symbols displayed by the operating and display device.

As FIG. 1 also shows, the items to be washed 12 to 14 are net angeord one above the other in the receiving area 2. Each washware receptacle 12 to 14 can optionally be moved into or out of the receptacle area 2. In particular, each washware receptacle 12 to 14 can be pushed or moved into the receiving area 2 in an insertion direction E and can be pulled out or withdrawn from the receiving area 2 in a pull-out direction A in a pull-out direction A counter to the insertion direction E.

FIG. 2 shows a schematic side view of the household appliance 1. As FIG. 2 shows, the door 3 can be brought from a closed state Z1 via any number of intermediate states Z2 to a completely open state Z3. In the intermediate state Z2, the door is denoted by the reference symbol 3 '. In the open state Z3, the door is denoted by the reference symbol 3 ″. When the door 3 is moved from the closed state Z1 to the open state Z3, the door 3 is pivoted relative to the receiving area 2 by an opening angle α. The opening angle α is defined as an angle between the door 3 and a flange running around the loading opening 6 of the receiving area 2. In the closed state Z1, the opening angle α is 0 °, in the intermediate state Z2 shown in FIG 15 to 25 ° and in the open state Z3 the opening angle α is 90 °.

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 top edge 17 connects the front side 15 to the rear side 16. The upper edge 17 is preferably positioned perpendicularly both to the front side 15 and to the rear side 16.

The household appliance 1 comprises an operating and display device 18 provided in or on the door 3. With the aid of the operating and display device 18, the household appliance 1 can be operated and, for example, an operating state of the same can be displayed. The operating and display device 18 can be, for example, a touchscreen or comprise one. Furthermore, the operating and display device 18 can have any other operating and display elements. For example, the operating and display device 18 can comprise switches, displays, light-emitting diodes or the like.

The operating and display device 18 comprises a first section 19 which is assigned to the front side 15, a second section 20 which is assigned to the upper edge 17, and a third section 21 which is assigned to the rear side 16. From the first section 19 is arranged on or on the front 15. The second section 20 is arranged at or on the upper edge 17. The third section 21 is arranged on or on the rear side 16. The operating and display device 18 thus revolves around the upper edge 17.

Optionally, one of the sections 19 to 21 can also be omitted. For example, the operating and display device 18 can be configured without the third section 21 assigned to the rear side 16. In this case, the operating and display device 18 is arranged only on or on the front side 15 and on or on the upper edge 17. The operating and display device 18 is also assigned a control unit 22 which can be arranged within the door 3, for example. For example, washing programs of the household appliance 1 can be stored in the control unit 22.

The first section 19 of the operating and display device 18 is suitable for displaying relevant information and / or enabling functions in the closed state Z1 of the door 3. In the present case, “information” can be understood to mean a symbol, a pictogram or a sequence of letters and / or numbers. Relevant information displayed by the operating and display device 18 in the closed state Z1 can be, for example, a remaining running time of a washing program of the household appliance 1. Under a "function", for example, the selection of different op- Functions of a washing program, such as "speed on demand" or "silence on demand", starting or pausing the washing program or the like should be understood. The function can be "enabled" by the fact that the information, for example a symbol displayed by the operating and display device 18, is selected or selected by a user by touching a finger.

The second section 20 of the operating and display device 18 is suitable for displaying relevant information in the intermediate state Z2 and / or for enabling functions. The relevant information or functions include the selection of the washing program and / or options for the washing program or starting the washing program. In particular, general operation of the household appliance 1 is possible in the intermediate state Z2, since this is the most ergonomic position for the user. For example, in the intermediate state Z2, using the operating and display device 18, the household appliance 1 can be operated and the washing program selected.

The third section 21 of the operating and display device 18 is suitable for displaying relevant information and / or enabling functions in the open state Z3 of the door 3. For example, in the open state Z3, deficiency indicators, such as a lack of softening salt, rinse aid or cleaning agent, can be displayed with the aid of the operating and display device 18. Furthermore, with the aid of the operating and display device 18, explanations, such as brief instructions for the household appliance 1, can be displayed.

4 shows a development of the operating and display device 18. That is, in FIG. 4 all sections 19 to 21 of the operating and display device 18 are arranged in a plane and not, as shown in FIG. 3, Positioned in a U-shape. As mentioned above, each section 19 to 21 is assigned at least one item of information x, y, z, which is only displayed by the operating and display device 18 when the door 3 is in the corresponding state Z1 to Z3. For example, the information x is only displayed when the door 3 is in the closed state Z1. The information y is accordingly only displayed when the door 3 is in the intermediate state Z2. The information z, however, is only displayed when the door 3 is in the open state Z3. ok

Furthermore, it is also possible that the respective information x, y, z, as shown in FIG. 4 using the information x with arrows 23, 24, moves over the operating and display device 18 as a function of the opening angle a. For example, when the door 3 is moved from the closed state Z1 to the intermediate state Z2, the information x moves from the first section 19 of the operating and display device 18 to the second section 20 of the same. Conversely, when the door 3 is moved from the intermediate state Z2 to the closed state Z1, the information x can migrate back from the second section 20 to the first section 19. When the door 3 is moved from the intermediate state Z2 to the open state Z3, the information x accordingly migrates from the second section 20 of the operating and display device 18 to the third section 21 of the same. Conversely, when the door 3 is moved from the open state Z3 to the intermediate state Z2, the information x can wander back from the third section 21 to the second section 20.

With the aid of the operating and display device 18, it is thus possible to display to a user only the information x, y, z or functionalities relevant to the respective opening angle a. Furthermore, printed pictograms or symbols can be dispensed with, since these can be digitized and displayed with the aid of the operating and display device 18. It is thus possible to display to the user only the respective information x, y, z that is relevant at the corresponding point in time and to link this to the opening angle α of the door 3. For example, when the door 3 is in the closed state Z1, only the remaining running time, the options start or pause and extra functions, such as "speed on demand" and " silence on demand "is displayed.

When the door 3 is opened, some information x, y, z becomes irrelevant, such as, for example, “speed on demand” or “silence on demand”. The aforementioned functions who are only switched on when the household appliance 1 is already running. Other information x, y, z also remain relevant when the door 3 is opened, such as the start / pause function, for example. There is also information x, y, z that changes. The clock at the remaining time display on the outside of door 3 becomes a clock that shows the program duration. This simplifies the selection of the program.

The transformation of information x, y, z can be visualized by an animation, so that it becomes clearer for the user that only the relevant information x, y, z is in his field of vision and the household appliance 1 in an intelligent way on its behavior reacted. Because the user is only shown the information x, y, z that match the opening angle α of the door 3, information overflow can be prevented. This increases the ease of use. Although the present invention has been described on the basis of exemplary embodiments, it can be modified in many ways.
