A spray device is provided that is operable to spray at least one jet of liquid and a dissolving chamber having a chamber floor with at least one aperture is mounted to the storage container. The storage container and the spray device are mounted relative to one another such that the dissolving chamber is wetted with liquid that has been sprayed by the spray device.

a dissolving chamber having a chamber floor with at least one aperture, the dissolving chamber being mounted to the storage container and the storage container and the spray device being mounted relative to one another such that the dissolving chamber is wetted with liquid that has been sprayed by the spray device,

wherein the aperture is shaped so that the jet follows the aperture along a portion of a movement path of the spray device, the aperture being a slot shape with a length longer than a width and the portion corresponding to the length.

2. The dishwasher as claimed in claim 1 , wherein the spray device is a rotating spray arm having at least one spray nozzle.

3. The dishwasher as claimed in claim 1 , wherein the aperture is shaped to correspond to, and is vertically aligned with, a nozzle that forms the at least one jet of liquid along the portion of the movement path.

4. The dishwasher as claimed in claim 1 , wherein the movement path is arcuate.

5. The dishwasher as claimed in claim 1 , wherein the storage container comprises a plurality of openings adapted to allow the jet of liquid to contact the items to be washed and a smallest opening of the plurality of openings is larger than the at least one aperture.

6. The dishwasher as claimed in claim 1 , wherein the dissolving chamber is adapted to prevent contact between the items to be washed and detergent in the dissolving chamber.

7. The dishwasher as claimed in claim 1 , wherein the slot is arcuate and the length is arcuate.

8. A dishwasher comprising:

a washing chamber defining a washing volume in which items to be washed are disposed;

a storage container disposed in the washing chamber for retaining the items to be washed at a predetermined storage location within the washing volume;

a spray device operable to spray at least one jet of liquid; and

a dissolving chamber adapted to prevent contact between the items to be washed and detergent in the dissolving chamber, the dissolving chamber having a chamber floor with at least one aperture configured to permit direct entry of at least a portion of the at least one jet of liquid, the dissolving chamber being mounted to the storage container and the storage container and the spray device being mounted relative to one another such that the dissolving chamber is wetted with liquid that has been sprayed by the spray device,

wherein a nozzle that generates the at least one jet of liquid is vertically aligned with the at least one aperture in at least one position of the spray device.

9. The dishwasher as claimed in claim 8 , wherein the jet of liquid strikes the chamber floor at right angles.

10. The dishwasher as claimed in claim 8 , wherein the dissolving chamber is disposed on a front side wall of the storage container.

11. The dishwasher as claimed in claim 8 , wherein the dissolving chamber is disposed on a front wall of the storage container.

12. The dishwasher as claimed in claim 8 , wherein the dissolving chamber is disposed in the middle of the storage container.

13. The dishwasher as claimed in claim 8 , wherein the spray device includes a spray base and at least one spray pipe communicated with the spray base and at least one outlet of the at least one spray pipe is disposed under the dissolving chamber.

14. The dishwasher as claimed in claim 8 , wherein the spray device is a selected one of a spray nozzle and a sprinkler head.

15. The dishwasher as claimed in claim 8 , wherein the chamber floor of the dissolving chamber has slit-shaped apertures.

16. The dishwasher as claimed in claim 15 , wherein the slit-shaped apertures of the chamber floor are arranged one of longitudinally and transversely.

17. The dishwasher as claimed in claim 8 , wherein the chamber floor is embodied in an inward-facing arched shape.

18. The dishwasher as claimed in claim 8 , wherein the dissolving chamber can be closed by means of a lid.

20. The dishwasher as claimed in claim 18 , wherein at least the lid and at least one side wall of the dissolving chamber are permeable to liquid.

21. The dishwasher as claimed in claim 8 , wherein a nozzle that generates the at least one jet of liquid is vertically aligned with the at least one aperture along a range of movement of the spray device.

22. The dishwasher as claimed in claim 21 , wherein the movement path is arcuate.

23. The dishwasher as claimed in claim 8 , wherein the storage container comprises a plurality of openings adapted to allow the jet of liquid to contact the items to be washed and a smallest opening of the plurality of openings is larger than the at least one aperture.

24. The dishwasher as claimed in claim 8 , wherein the aperture is shaped to correspond to a portion of a movement path of the spray device.

25. The dishwasher as claimed in claim 8 , wherein the storage container and the spray device are mounted relative to one another such that the liquid that wets the dissolving chamber is prevented from being deflected off the floor of the dissolving chamber onto a side wall of the washing chamber.
