(54) A screen filter for a liquid-conducting device, in particular a dishwashing machine


(57) The invention reveals a screen filter for a liquid-conducting device, in particular a household dishwashing machine, that is designed flat with flow holes, separates the water-conducting space from a drainage shaft and lies at the bottom of the water-conducting space, sealing the perimeter. The invention provides that the screen is designed and manufactured as a plastic-injection mould part, that it is divided on its underside at least in partitions by injected reinforcement links in fields with flow holes arranged in rows and that it is provided with defined bearing surfaces for retainers; in doing so a screen filter is created that can be manufactured cost-effectively with optimal use of its surface space for a large overall flow surface space, but with the smallest flow holes possible, that is nonetheless sufficiently stable and rigid.
