Definitions
- the present invention relates to a household appliance, in particular a water-conducting household appliance.
- Many household appliances such as household dishwashers, include a pivotable door.
- the household appliance may include a device that can compensate for the weight of the door to prevent falling of the door in the open position.
- the device comprises, for example, a cable which is connected at one end to the door and at the other end to a spring element.
- the spring element in turn is connected, for example, with a housing of the household appliance.
- the spring In an opening movement of the door, for example, the spring is biased so that a spring force by means of the rope so engages the door, that falling of the door is avoided.
- friction elements can be provided which make a pivoting movement of the door difficult. A corresponding frictional force can, in the open position of the door, form a difference between the weight of the door pulling on the cable and the spring force.
- EP 0 541 974 A1 shows a dishwasher with a device housing in which an electromotive drive is provided. With the aid of the electric motor drive, for example, a device door of the dishwasher can be completely or partially closed or opened.
- an object of the present invention is to provide an improved home appliance.
- a household appliance in particular a water-conducting domestic appliance, comprising a housing, a door pivotally connected to the housing, a cable connected to the door, a roller in contact with the cable and a motor which is adapted to the roller to drive the cable so that a pivoting movement of the door is effected.

- the door is pivotally connected to the housing by means of a hinge.
- the door is pivoted to a floor on which the household appliance stands.
- “Roll” in this case means, for example, a rotatably mounted element, which in particular has a rotational symmetry to a central axis. The role may for example be referred to as a pulley.
- a cable is in contact with the roller along a wrap angle, wherein, for example, the wrap angle, in particular substantially, remains constant during a movement of the cable. In other words, for example, an amount of a contact area between the rope and the roller remains constant.
- the rope comprises plastic or metal.
- the rope may comprise yarn or textiles, in particular natural fibers and / or man-made fibers.
- the rope is formed of a plurality of cable sections, which are mechanically connected to each other.

- the door has a lever with which one end of the cable is connected, wherein the door, the motor and the cable are arranged such that a change of a tensile force on the lever by means of the motor and the cable, the pivoting movement the door causes.
- the door comprises a plate-shaped door section, the hinge and the lever.
- the door section can be pivoted about the hinge.
- the lever is formed on the door section in such a way that the change in the tensile force on the lever causes the pivoting movement of the door section.
- the door may include another lever to which another rope is connected.
- the levers may each be arranged on outer sides of an underside of the door section.
- the lever and / or the levers are rigid (not rotatable) connected to the door section.
- the household appliance comprises a spring element, which is connected to the housing and to the cable and is adapted to at least partially compensate for a weight force of the door.
- the spring element is preferably a helical spring.
- a spring characteristic of the spring element is progressive, degressive or linear.
