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

1 - 15 . (canceled)

16 . 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 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.

17 . The household dishwasher of claim 16 , further comprising a receptacle accommodated in the dishwasher interior for the item to be washed, said placement region being provided on the receptacle.

18 . The household dishwasher of claim 17 , wherein the spraying facility is rotatably mounted on the receptacle.

19 . The household dishwasher of claim 16 , wherein the spraying facility is arranged below the placement region as viewed along a direction of gravity.

20 . The household dishwasher of claim 16 , 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.

21 . The household dishwasher of claim 16 , wherein the placement region comprises a geometry configured to fan out a spray jet of the spraying facility.

22 . The household dishwasher of claim 16 , 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.

23 . The household dishwasher of claim 16 , wherein the spraying facility is driven by the wash liquor and/or fresh water emerging from the spraying facility, said blocking facility mechanically blocking the spraying facility for blocking the rotational movement of the spraying facility.

24 . The household dishwasher of claim 23 , 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.

25 . The household dishwasher of claim 24 , 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.

26 . The household dishwasher of claim 24 , wherein the rocker is mounted off-center.

27 . The household dishwasher of claim 24 , wherein a first lever arm of the cleaning agent is larger than a second lever arm of the counterweight.

28 . The household dishwasher of claim 24 , 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.

29 . The household dishwasher of claim 23 , 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.

30 . The household dishwasher of claim 29 , wherein the placement region releases the spraying facility as soon as a weight force of the cleaning agent is smaller than the spring force.
