Abstract

A household appliance includes a housing, a door pivotably connected to the housing, a cable connected to the door, a roller in contact with the cable, and a motor configured to drive the roller to move the cable such as to effect a pivoting movement of the door.

First claim

The invention claimed is:

1. A household appliance, comprising:
a housing;
a door pivotably connected to the housing;
a cable connected to the door;
a roller in contact with the cable;
a motor configured to drive the roller to move the cable such as to effect a pivoting movement of the door;
a control device configured to actuate the motor so as to cause the pivoting movement of the door; and
a user interface configured to communicate with the control device to actuate the motor.

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

3. The household appliance of claim 2 , wherein the water-using household appliance is a household dishwasher.

4. The household appliance of claim 1 , wherein the roller and the cable are configured to effect a transfer of drive force from the roller to the cable exclusively via a friction force-fit.

5. The household appliance of claim 1 , wherein the door includes a lever, to which one end of the cable is connected, the door, the motor and the cable being configured to cause the pivoting movement of the door in response to a change in a tensile force on the lever effected by the motor and the cable.

6. The household appliance of claim 1 , further comprising a spring element connected to the housing and to the cable, said spring element configured to at least partially compensate for a weight of the door.

7. The household appliance of claim 1 , wherein the cable has a wrap angle around the roller of between 360° and 540°.

8. The household appliance of claim 1 , wherein the cable has a wrap angle around the roller of between 400° and 500°.

9. The household appliance of claim 1 , wherein the cable has a wrap angle around the roller of between 425° and 475°.

10. The household appliance of claim 1 , wherein the cable has a wrap angle around the roller of between 445° and 455°.

11. The household appliance of claim 1 , wherein the motor is connected in driving relationship to the roller.

12. The household appliance of claim 11 , further comprising a gearing, said motor being connected in driving relationship to the roller via the gearing.

13. The household appliance of claim 12 , wherein the gearing is a worm gearing.

14. The household appliance of claim 12 , wherein the gearing is configured to inhibit a movement of the roller.

15. The household appliance of claim 1 , wherein the control device is configured to actuate the motor such that the door executes a complete opening movement and/or a partial opening movement and/or a complete closing movement and/or a partial closing movement.

16. The household appliance of claim 1 , wherein the cable and the roller are configured to slide the cable over the roller when an opening angle of the door changes as a result of a manual force acting on the door.

17. The household appliance of claim 1 , wherein the motor is embodied as an electric motor, as a hydraulic motor or as a pneumatic motor.

18. The household appliance of claim 1 , further comprising a deflection roller configured to deflect the cable between the roller and the door.
