Abstract

In order to produce a cleaning device which cleans in a particularly effective manner wherein the cleaning device comprises a cleaning chamber for accommodating a workpiece requiring cleaning and a fluid transfer device for transferring at least one fluid into the cleaning chamber and/or out of the cleaning chamber and wherein the fluid transfer device comprises at least one nozzle in the form of a slotted nozzle extending along a slot axis and said fluid is arranged to be fed into the cleaning chamber or fed out of the cleaning chamber by means of said fluid transfer device in a direction transverse to the slot axis, it is proposed that the cleaning device comprise a slotted nozzle moving device for moving at least a part of the slotted nozzle.

Claims (20)

1. A cleaning device comprising a cleaning chamber for accommodating a workpiece requiring cleaning and a fluid transfer device for transferring at least one fluid into the cleaning chamber and/or out of the cleaning chamber,

wherein the fluid transfer device comprises at least one nozzle in the form of a slotted nozzle which extends along a slot axis and the at least one fluid is arranged to be fed into the cleaning chamber or fed out of the cleaning chamber by means of said slotted nozzle in a direction transverse to the slot axis,

wherein the cleaning device comprises a slotted nozzle moving device for moving at least a part of the slotted nozzle,

wherein the cleaning chamber can be filled with a liquid bath into which a slotted nozzle opening of the slotted nozzle is arranged to be dipped,

said cleaning device further comprising a slot-width adjusting device for adjusting the slot-width of the slotted nozzle.

2. A cleaning device in accordance with claim 1 , wherein the fluid transfer device comprises a fluid feed-in device for feeding at least one fluid into the cleaning chamber.

3. A cleaning device in accordance with claim 1 , wherein the fluid transfer device comprises a fluid feed-out device for feeding at least one fluid out of the cleaning chamber.

4. A cleaning device in accordance with claim 1 , wherein the slotted nozzle is pivotal or rotatable by means of the slotted nozzle moving device.

5. A cleaning device in accordance with claim 1 , wherein the slot-width adjusting device comprises at least one adjusting element which is movable along an adjustment axis.

6. A cleaning device in accordance with claim 5 , wherein the adjustment axis is substantially parallel to the slot axis.

7. A cleaning device in accordance with claim 5 , wherein the at least one adjusting element is pivotal or rotatable about the adjustment axis.

8. A cleaning device in accordance with claim 5 , wherein the at least one adjusting element is pivotal or rotatable independently of linear movement along the adjustment axis of the at least one adjusting element.

9. A cleaning device in accordance with claim 5 , wherein the slot-width adjusting device and the slotted nozzle moving device are operable independently of one another.

10. A cleaning device in accordance with claim 1 , wherein the cleaning chamber has at least one chamber wall and in that a direction in which the fluid is fed-in through the slotted nozzle is adjustable in such a manner that at least one section of at least one chamber wall of the cleaning chamber can be cleaned by means of the fluid being fed-in.

11. A cleaning device in accordance with claim 1 , further comprising a fluid line system which is connected in fluid conveying manner to the fluid transfer device for the purposes of supplying or removing a fluid and comprises a plurality of fluid lines for mutually differing fluids.

12. A cleaning device in accordance with claim 1 , further comprising a workpiece moving device for moving a workpiece that is accommodated in the cleaning chamber relative to the slotted nozzle.

13. A cleaning device in accordance with claim 1 , wherein at least a section of a workpiece requiring cleaning is arranged to be dipped into the liquid bath.

14. A method for the cleaning of a workpiece in which a workpiece is arranged in a cleaning chamber and at least one fluid is fed into the cleaning chamber or fed out from the cleaning chamber by a fluid transfer device which comprises a nozzle in the form of a slotted nozzle which extends along a slot axis and wherein the direction of feed is transverse to the slot axis, wherein at least a part of the slotted nozzle is moved relative to the cleaning chamber by a slotted nozzle moving device,

wherein the cleaning chamber is filled with a liquid bath into which a slotted nozzle opening of the slotted nozzle is dipped,

said fluid transfer device further comprising a slot-width adjusting device for adjusting the slot-width of the slotted nozzle.
