Abstract

A lifting device for a receptacle for items to be washed of a dishwasher, in particular a household dishwasher is constructed to lift the receptacle from a starting position, optionally via at least one intermediate position, into an end position or to lower the washing item receptacle from the end position, optionally via at least one intermediate position, into the starting position. The lifting device includes a braking device having at least one damping element which is designed to brake a movement of the 32-receptacle in particular during the lowering process.

First claim

The invention claimed is:

1. A lifting device for a receptacle for items to be washed of a dishwasher, said lifting device being constructed to lift the receptacle for items to be washed from a starting position into an end position or to lower the receptacle from the end position into the starting position, said lifting device comprising:
a braking device including a damping element configured to brake a movement of the receptacle,
a scissors lift configured to lift and lower the receptacle, wherein the scissors lift comprises first and second scissor arms which intersect one another and are pivotably connected to one another at a pivot point to allow lifting and lowering of the receptacle as a function of a pivot angle between the first and second scissor arms, and
an actuation lever pivotably disposed at a pivot point on the receptacle and having an end segment pivotably connected to one of the first and second scissor arms of the scissors lift via an intermediate lever, the actuation lever also being operably connected to the damping element for allowing actuation of the damping element.

2. The lifting device of claim 1 , wherein the damping element is configured to have an adjustable damping effect.

3. The lifting device of claim 2 , wherein the damping effect of the damping element is adjustable such as to brake the movement of the receptacle more significantly during lowering of the receptacle than during lifting of the receptacle.

4. The lifting device of claim 1 , wherein the damping element is configured so as to be activated or deactivated.

5. The lifting device of claim 1 , wherein the damping element is configured such that the movement of the receptacle is only braked during lowering of the receptacle and unbraked during lifting of the receptacle.

6. The lifting device of claim 1 , further comprising a receptacle carrier for carrying the receptacle, said damping element being arranged in one of three ways, a first way in which the damping element is arranged between the first and second scissor arms, a second way in which the damping element is arranged between the first and second scissor arms and the receptacle carrier, a third way in which the damping element is arranged at the pivot point of the first and second scissor arms.

7. The lifting device of claim 1 , wherein the scissors lift is configured such that in a retracted state thereof the lifting device is movable out of and into a dishwasher cavity of the dishwasher.

8. The lifting device of claim 1 , further comprising a drive facility configured to apply a supporting force to support a manual lifting or lowering of the receptacle.

9. The lifting device of claim 8 , wherein the drive facility is constructed in the form of a spring element.

10. A dishwasher, comprising:
a dishwasher cavity;
a receptacle for items to be washed, said receptacle being receivable in the dishwasher cavity; and
a lifting device constructed to lift the receptacle from a starting position into an end position or to lower the receptacle from the end position into the starting position, said lifting device comprising:
a braking device including a damping element configured to brake a movement of the receptacle,
a scissors lift configured to lift and lower the receptacle, wherein the scissors lift comprises first and second scissor arms which intersect one another and are pivotably connected to one another at a pivot point to allow lifting and lowering of the receptacle as a function of a pivot angle between the first and second scissor arms, and
an actuation lever pivotably disposed at a pivot point on the receptacle and having an end segment pivotably connected to one of the first and second scissor arms of the scissors lift via an intermediate lever, the actuation lever also being operably connected to the damping element for allowing actuation of the damping element.

11. The dishwasher of claim 10 , constructed in the form of a household dishwasher.

12. The dishwasher of claim 10 , wherein the damping element is configured to have an adjustable damping effect.

13. The dishwasher of claim 12 , wherein the damping effect of the damping element is adjustable such as to brake the movement of the receptacle more significantly during lowering of the receptacle than during lifting of the receptacle.

14. The dishwasher of claim 10 , wherein the damping element is configured so as to be activated or deactivated.

15. The dishwasher of claim 10 , wherein the damping element is configured such that the movement of the receptacle is only braked during lowering of the receptacle and unbraked during lifting of the receptacle.

16. The dishwasher of claim 10 , wherein the lifting device includes a receptacle carrier for carrying the receptacle, said damping element being arranged in one of three ways, a first way in which the damping element is arranged between the first and second scissor arms, a second way in which the damping element is arranged between the first and second scissor arms and the receptacle carrier, a third way in which the damping element is arranged at the pivot point of the first and second scissor arms.

17. The dishwasher of claim 10 , wherein the scissors lift is configured such that in a retracted state thereof the lifting device is movable out of and into a dishwasher cavity of the dishwasher.

18. The dishwasher of claim 10 , further comprising a drive facility configured to apply a supporting force to support a manual lifting or lowering of the receptacle.

19. The dishwasher of claim 18 , wherein the drive facility is constructed in the form of a spring element.
