Abstract

A household dishwasher includes a dishwasher interior, a spraying facility rotatably mounted in the dishwasher interior for spraying wash liquor and/or fresh water upon an item to be washed received in the dishwasher interior, a placement region for placement of a cleaning agent, and a blocking facility configured to block a rotational movement of the spraying facility in such a manner that the spraying facility during blocking of the spraying facility selectively sprays the placement region with wash liquor and/or fresh water in order to dissolve the cleaning agent.

First claim

The invention claimed is:

1. A household dishwasher, comprising:
a dishwasher interior;
a spraying facility rotatably mounted in the dishwasher interior for spraying wash liquor and/or fresh water upon an item to be washed received in the dishwasher interior;
a metering facility located on a wall or a door within the dishwasher interior to receive a cleaning agent;
a placement region for placement of the cleaning agent, the placement region having an open top and aligned with the metering facility to receive the cleaning agent from the metering facility during a wash cycle of the household dishwasher; and
a blocking facility configured to block a rotational movement of the spraying facility in such a manner that the spraying facility during blocking of the spraying facility selectively sprays the placement region with wash liquor and/or fresh water in order to dissolve the cleaning agent.

2. The household dishwasher of claim 1 , further comprising a receptacle accommodated in the dishwasher interior for the item to be washed, said placement region being provided on the receptacle.

3. The household dishwasher of claim 2 , wherein the spraying facility is rotatably mounted on the receptacle.

4. The household dishwasher of claim 1 , wherein the spraying facility is arranged below the placement region as viewed along a direction of gravity.

5. The household dishwasher of claim 1 , wherein the blocking facility is configured to unblock the spraying facility as soon as a residual weight of the cleaning agent falls below a predetermined limit value.

6. The household dishwasher of claim 1 , wherein the placement region comprises a geometry configured to fan out a spray jet of the spraying facility.

7. The household dishwasher of claim 1 , further comprising a drive element configured to actively drive the spraying facility, said blocking facility controlling the drive element such as to block the rotational movement of the spraying facility.

8. The household dishwasher of claim 1 , wherein the spraying facility is drivable by the wash liquor and/or fresh water emerging from the spraying facility, said blocking facility configured to mechanically block the spraying facility for blocking the rotational movement of the spraying facility.

9. The household dishwasher of claim 8 , wherein the blocking facility comprises a rotatably mounted rocker which has the placement region at a first end portion and a counterweight to the cleaning agent at a second end portion that is remote from the first end portion, said placement region blocking the rotational movement of the spraying facility when in contact with the spraying facility.

10. The household dishwasher of claim 9 , wherein the placement region comprises a stop which is in contact with a corresponding counter stop of the spraying facility so as to block the rotational movement of the spraying facility.

11. The household dishwasher of claim 9 , wherein the rocker is mounted off-center.

12. The household dishwasher of claim 9 , wherein a first lever arm of the cleaning agent is larger than a second lever arm of the counterweight.

13. The household dishwasher of claim 9 , wherein the counterweight is modifiable and/or a bearing location of the rocker is displaceable in order to adapt the blocking facility to a different type of the cleaning agent.

14. The household dishwasher of claim 8 , wherein the placement region is mounted in the dishwasher interior for rotation about an axis of rotation, said cleaning agent displacing the placement region against a spring force of a spring element in such a manner that the placement region mechanically blocks the spraying facility so as to block the rotational movement of the spraying facility.

15. The household dishwasher of claim 14 , wherein the placement region releases the spraying facility as soon as a weight force of the cleaning agent is smaller than the spring force.

16. The household dishwasher of claim 1 , wherein the placement region is box- shaped or trough-shaped.

17. The household dishwasher of claim 1 , wherein the placement region is a tray.

18. A household dishwasher, comprising:
a dishwasher interior;
a spraying facility rotatably mounted in the dishwasher interior for spraying wash liquor and/or fresh water upon an item to be washed received in the dishwasher interior, the spraying facility rotationally drivable by wash liquor and/or fresh water emerging from the spraying facility;
a placement region for placement of a cleaning agent; and
a blocking facility comprising a rotatably mounted rocker which has the placement region at a first end portion and a counterweight to the cleaning agent at a second end portion that is remote from the first end portion, the blocking facility configured so that the placement region mechanically blocks a rotational movement of the spraying facility in such a manner that the spraying facility, during blocking of the spraying facility, selectively sprays the placement region with wash liquor and/or fresh water in order to dissolve the cleaning agent.

19. The household dishwasher of claim 18 , further comprising a receptacle accommodated in the dishwasher interior for the item to be washed, the placement region being provided on the receptacle.

20. The household dishwasher of claim 18 , wherein the spraying facility is arranged below the placement region as viewed along a direction of gravity.
