The wiper device at least as claimed in claim 3, characterized in that the inner circle guide unit (14a; 14b) has at least one second nozzle element (50b). 5. The wiper device as claimed in claim 4, characterized in that the at least one second nozzle element (50b) is arranged in front of the guide recess (40a; 40b), as viewed in the first wiping direction (42a). 6. The wiper device at least as claimed in claim 1, wherein the at least one nozzle element is an at least one first nozzle element, characterized in that the inner circle guide unit (14a; 14b) has at least one second nozzle element (50b). 7. The wiper device as claimed in claim 6, characterized in that the at least one second nozzle element (50b) is arranged in front of the guide recess (40a; 40b), as viewed in a first wiping direction (42a). 8. A system comprising a wiper device as claimed in claim 1 and the wiper blade (12a; 12b) which is guided by the inner circle guide unit (14a; 14b). 9. The wiper device as claimed in claim 1, characterized in that the at least one nozzle element (18a; 18b) is disposed laterally adjacent to the guide recess for receiving the wiper blade in an interlocking manner. 10. The wiper device as claimed in claim 1, characterized in that a tube (52a) that conveys the washing liquid is fastened to the nozzle element (18a), the tube terminating at the inner circle guide element (16a; 16b). 11.
