Abstract

A lifting device for a dish receptacle of a dishwasher, in particular a household dishwasher, includes a drive facility configured to assist a manual raising or lowering of the dish receptacle between a start position and an end position by applying a supporting force. A control facility activates the drive facility as a function of a manual actuation force when the dish receptacle is raised or lowered manually and a sensor facility is provided to detect the manual actuation force. A transmission facility transmits the manual actuation force from a handle of the dish receptacle to the sensor facility.

First claim

The invention claimed is:

1. A lifting device for a dish receptacle of a dishwasher, said lifting device comprising:
a drive facility configured to assist a manual raising or lowering of the dish receptacle between a start position and an end position by applying a supporting force,
a control facility configured to activate the drive facility as a function of a manual actuation force when the dish receptacle is raised or lowered manually,
a sensor facility configured to detect the manual actuation force, and
a transmission facility configured to transmit the manual actuation force from a handle of the dish receptacle to the sensor facility,
wherein the transmission facility comprises a mechanical transmission member including a control cable, thereby to mechanically couple the handle of the dish receptacle to the sensor facility,
wherein the control cable is directly coupled to the handle of the dish receptacle, and
wherein the sensor facility is configured to detect a movement of the handle as the handle is acted upon by the manual actuation force.

2. The lifting device of claim 1 , wherein the sensor facility is arranged inside a wash container of the dishwasher.

3. The lifting device of claim 1 , wherein the control facility activates the drive facility in such a manner that a movement speed of the dish receptacle is proportional to the manual actuation force and/or the supporting force is proportional to the manual actuation force.

4. The lifting device of claim 1 , wherein the movement speed and/or the supporting force is/are directly proportional to the manual actuation force.

5. The lifting device of claim 1 , further comprising a drag lever having a bearing point for support on the dish receptacle, said drag lever configured to stop the dish receptacle as it is raised or lowered by fixing the dish receptacle to the drag lever in such a manner that the bearing point of the drag lever is pivotable in relation to the dish receptacle and immobile linearly.

6. The lifting device of claim 5 , wherein the drag lever has a further bearing point for support on a wash container of the dishwasher, a sensor line of the sensor facility being dimensioned such as to extend out of the wash container through the further bearing point of the drag lever.

7. The lifting device of claim 5 , wherein the sensor facility is provided in or on the bearing point of the drag lever.

8. The lifting device of claim 5 , wherein the sensor facility is provided on the drag lever and includes an actuation element arranged on the dish receptacle.

9. The lifting device of claim 8 , wherein the actuation element is a magnetic element.

10. The lifting device of claim 5 , wherein the bearing point of the drag lever includes a block mechanism which is provided on the dish receptacle, and a block counter-mechanism which is provided on the drag lever.

11. The lifting device of claim 10 , wherein the block mechanism and the block counter-mechanism are rotatable into one another, when the dish receptacle is moved out of a wash container linearly in the start position.

12. The lifting device of claim 11 , wherein the block mechanism and the block counter-mechanism are movable from a release state, in which the dish receptacle is movable linearly in relation to the drag lever, to a blocking state, in which the bearing point of the drag lever is pivotable in relation to the dish receptacle and immobile linearly.

13. The lifting device of claim 12 , wherein the block mechanism and the block counter-mechanism are movable from the release state to the blocking state by raising the dish receptacle.

14. The lifting device of claim 1 , wherein the dishwasher comprises a household dishwasher.

15. A dishwasher, comprising:
a wash container,
a dish receptacle accommodated in the wash container and including a handle, and
a lifting device comprising a drive facility configured to assist a manual raising or lowering of the dish receptacle between a start position and an end position by applying a supporting force, a control facility configured to activate the drive facility as a function of a manual actuation force when the dish receptacle is raised or lowered manually, a sensor facility configured to detect the manual actuation force, and a transmission facility configured to transmit the manual actuation force from the handle of the dish receptacle to the sensor facility,
wherein the transmission facility comprises a mechanical transmission member including a control cable, thereby to mechanically couple the handle of the dish receptacle to the sensor facility,
wherein the control cable is directly coupled to the handle of the dish receptacle, and
wherein the sensor facility is configured to detect a movement of the handle as the handle is acted upon by the manual actuation force.

16. The dishwasher of claim 15 , wherein the dishwasher comprises a household dishwasher.

17. A lifting device for a dish receptacle of a dishwasher, said lifting device comprising:
a drive facility configured to assist a manual raising or lowering of the dish receptacle between a start position and an end position by applying a supporting force,
a control facility configured to activate the drive facility as a function of a manual actuation force when the dish receptacle is raised or lowered manually,
a sensor facility configured to detect the manual actuation force, and
a transmission facility configured to transmit the manual actuation force from a handle of the dish receptacle to the sensor facility,
wherein the transmission facility comprises a mechanical transmission member, thereby to mechanically couple the handle of the dish receptacle to the sensor facility,
further comprising a drag lever having a bearing point for support on the dish receptacle, said drag lever configured to stop the dish receptacle as it is raised or lowered by fixing the dish receptacle to the drag lever in such a manner that the bearing point of the drag lever is pivotable in relation to the dish receptacle and immobile linearly,
wherein the bearing point of the drag lever includes a block mechanism which is provided on the dish receptacle, and a block counter-mechanism which is provided on the drag lever,
wherein the block mechanism and the block counter-mechanism are rotatable into one another, when the dish receptacle is moved out of a wash container linearly in the start position, and
wherein the block mechanism and the block counter-mechanism are movable from a release state, in which the dish receptacle is movable linearly in relation to the drag lever, to a blocking state, in which the bearing point of the drag lever is pivotable in relation to the dish receptacle and immobile linearly.
