Figure 1 shows a household appliance 44a in an open state in a perspective view. In the present case, the household appliance 44a is designed, for example, as a domestic refrigeration appliance, in particular as a refrigerator and freezer combination appliance. Alternatively, however, it is also conceivable to design a domestic appliance as another domestic refrigerator, such as a refrigerator or freezer.

The household appliance 44a is provided in a known manner to cool food and other refrigerated goods. For this purpose, the household appliance 44a comprises a Device body 46a. The device body 46a defines an interior with a utility space 48a. The household appliance 44a further comprises a household appliance door 10a. The appliance door 10a is movable, in the present case in particular pivotally connected to the device body 46a. The appliance door 10a is pivotable about a pivot axis 50a, which is oriented vertically relative to a plane. In a closed state, the appliance door 10a is provided to close the working space 48a. Alternatively, a household appliance door could also be connected in a linearly movable manner to a device body. The appliance door 10a comprises a door leaf 12a. The door panel 12a defines a majority of the appliance door 10a. The door leaf 12a covers the working space 48a in the closed state.

The door racks 14a defines a longitudinal extension direction 30a. The longitudinal extension direction 30a is aligned perpendicular to the pivot axis 50a. The door rack 14a is for storage of food, such as beverage bottles, provided. The door racks 14a is arranged on the door leaf 12a, in particular fastened. The door rack 14a is arranged on a side facing the working space 48a and / or an inside of the door leaf 12a. The door racks 14a is also adjustable, in particular displaceable, arranged on the door leaf 12a. In the present case, the door rack 14a is displaceable in height direction and / or height adjustable. In principle, however, a door rack could also be adjustable in a horizontal direction. The door racks 14a can, in particular in the loaded state, be adjusted at least substantially continuously and / or at least substantially continuously between one, in particular lower, first height and one, in particular higher, second height.

The damping elements 60a are formed in this case as a rotary damper. Alternatively, however, it would also be possible to dispense with a damping unit. In addition, a damping unit could have exactly one damping element. Also, a damping unit could in principle be designed as a mechanical, hydraulic and / or pneumatic damper and / or as a friction brake.

FIGS. 8 to 10 show a further exemplary embodiment of the invention. The following descriptions and the drawings are essentially limited to the differences between the exemplary embodiments, wherein, with regard to identically named components, in particular with regard to components having the same reference numbers, in principle also to the drawings and / or the description of the other embodiments, in particular FIGS to 7, can be referenced. In order to distinguish the exemplary embodiments, the letter a is the reference symbol of the Embodiment in the figures 1 to 7 adjusted. In the exemplary embodiment of FIGS. 8 to 10, the letter a is replaced by the letter b.

The further exemplary embodiment of FIGS. 8 to 10 differs from the previous exemplary embodiments at least substantially by a configuration of a synchronization unit 22b of a bearing unit 16b of a household appliance door 10b.

In this case, first synchronization elements 24b of the synchronization unit 22b have an axis of rotation 28b which is aligned at least substantially perpendicular to a main extension plane of a door leaf 12b of the household appliance door 10b.

In addition, a connection unit 32b of the synchronization unit 22b has two connection elements 34b, 36b. A first connecting element 34b of the connecting elements 34b, 36b is designed as a toothed element, in the present case in particular as a toothed wheel. The first connection element 34b meshes with one of the first synchronization elements 24b. The first connection element 34b serves to reverse the direction of a movement transmitted between the first synchronization elements 24b. A second connecting element 36b of the connecting elements 34b, 36b is designed as a belt. In this case, the second connection element 36b connects another of the first synchronization elements 24b to the first connection element 34b. Alternatively, however, a connection unit could also have a plurality of connecting elements, for example at least three toothed elements.

In addition, the bearing unit 16b in this case comprises at least one tightening element 62b. The tightening element 62b serves in the present case to tighten the second connecting element 36b. Alternatively, however, a tightening element can also be dispensed with. reference numeral
