1. A filter insert for cleaning machines, in particular continuous-flow dishwashers, in which a batch to be cleaned runs through at least one treatment zone, the at least one treatment zone being assigned a washing tank, wherein the filter insert has a number of longitudinal ribs which run parallel to one another and delimit flumes, andwherein side faces of the longitudinal ribs are perforated and a bottom of the flumes has a closed surface. 2. The filter insert as claimed in claim 1, wherein the filter insert further includes a connection component for connection to the washing tank of the at least one treatment zone, above a circulating pump. 3. The filter insert as claimed in claim 2, wherein the connection component comprises a peripheral bearing surface for retaining a coarse screen. 4. The filter insert as claimed in claim 1, wherein the filter insert has a peripheral bearing surface for a coarse screen retaining coarser impurities. 5. The filter insert as claimed in claim 1, wherein the filter insert is designed in box form. 6. The filter insert as claimed in claim 1, wherein said longitudinal ribs are arranged in a division. 7. The filter insert as claimed in claim 1, wherein the longitudinal ribs have an essentially triangular cross section. 8. The filter insert as claimed in claim 7, wherein the longitudinal ribs are formed from side faces which are connected to one another along a ridge extending parallel to the flumes. 9. The filter insert as claimed in claim 7, wherein the side faces forming the longitudinal ribs have an orifice pattern, the orifices of which have a smaller cross section than a coarse screen covering the filter insert. 10. The filter insert as claimed in claim 7, wherein the side faces of the longitudinal ribs form at the ridge a taper angle which lies between 15° and 35°. 11. The filter insert as claimed in claim 1, wherein a bottom surface, in particular, of the filter insert in box form has an essentially zigzag-shaped profile. 12. The filter insert as claimed in claim 1, wherein, below each of the longitudinal ribs of the filter insert, a free space runs, through which washing water passing through the side faces of the longitudinal ribs drips off into the washing tank. 13. The filter insert as claimed in claim 1, wherein a width of a respective flume which is delimited by two longitudinal ribs corresponds to a division of the filter insert. 14. The filter insert as claimed in claim 1, wherein said flumes have outflow orifices or issue into a common outflow. 15. The filter insert as claimed in claim 1, wherein the flumes are arranged in a gradient. 16. The filter insert as claimed in claim 1, wherein the flumes are arranged with an inclination in a direction toward an outflow orifice. 17. The filter insert as claimed in claim 1, wherein the longitudinal ribs are connected to each other by closed surface portions. 18. The filter insert as claimed in claim 1, wherein the flumes are configured to flush away retained particles. 19. A filter insert for cleaning machines, the filter insert comprising: parallel longitudinal ribs;an orifice opening;closed surface portions connecting the longitudinal ribs to form flumes; andan orifice pattern formed on a portion of a side face of the parallel longitudinal ribs,wherein a bottom of the flumes has a closed surface, andwherein the flumes are inclined in a direction toward the orifice opening.
