Abstract

A household appliance includes a housing, a door pivotably connected to the housing, a cable having one end connected to the door, a motor, and a cable drum onto which the cable can be unwound at least in partial and from which the cable can be unwound at least in part. The cable and the motor interact such that the door pivots when winding the cable onto the cable drum or when the cable unwinds from the cable drum.

First claim

The invention claimed is:

1. A household appliance, comprising:
a housing;
a door pivotably connected to the housing by a hinge, the door comprising a lever;
a cable having one end connected to the lever;
a motor; and
a cable drum capable of allowing the cable to be wound at least in part thereon and allowing the cable to be unwound at least in part,
wherein the cable and the motor interact such that the door pivots when winding the cable onto the cable drum or pivots when the cable unwinds from the cable drum.

2. The household appliance of claim 1 , constructed in the form of a water-utilizing household appliance.

3. The household appliance of claim 1 , wherein the cable drum is drivably connected to the motor and/or is flange-mounted onto the motor.

4. The household appliance of claim 1 , further comprising a further cable having one end connected to the door, the cable and the further cable capable of being wound at least in part onto the cable drum in synchronism and capable of being unwound at least in part from the cable drum in synchronism, wherein the cable, the further cable and the motor interact such that the door pivots when winding the cable and the further cable onto the cable drum or pivots when the cable and the further cable unwind from the cable drum.

5. The household appliance of claim 1 , further comprising a spring element configured to compensate at least in part for a weight force of the door.

6. The household appliance of claim 5 , further comprising a rotational element configured to tension the spring element.

7. The household appliance of claim 6 , further comprising an auxiliary cable having an end connected to the spring element, said rotational element embodied as an auxiliary cable drum onto which the auxiliary cable is capable of being wound at least in part and from which the auxiliary cable is capable of being unwound at least in part.

8. The household appliance of claim 6 , wherein the rotational element is embodied as the lever that is drivably connected to the cable drum and is connected to the spring element.

9. The household appliance of claim 5 , wherein the spring element has a first end which is connected to another end of the cable, and a second end which is connected to at least one of the motor and the cable drum.

10. The household appliance of claim 1 , further comprising a coupler configured to disconnect a drive connection between the motor and at least one of the cable drum and the cable.

11. The household appliance of claim 1 , further comprising a control unit configured to control the motor in such a manner as to cause the door to perform a pivot movement.

12. The household appliance of claim 11 , wherein the control unit is configured to switch the motor into a generator mode in order to generate a resistance against the pivot movement of the door.

13. The household appliance of claim 11 , further comprising an operator interface configured to communicate with the control unit.

14. The household appliance of claim 1 , further comprising an output apparatus configured to output an acoustic signal and/or an optical signal during a pivot movement of the door.

15. The household appliance of claim 1 , further comprising a locking brake configured to prevent at least one action selected from the group consisting of winding-on movement of the cable, unwinding movement of the cable drum, and pivot movement of the door.
