The insert body (9), together with the upper part (2) of the housing, forms a chamber system with three sections (II). Liquid can be introduced into the chambers. For flushing out detergent, the liquid can be sprayed through openings in the insert body (9). The outline of the insert body (9) is surrounded by ribs (7) which are shaped on the underside of the top housing part (2) and limit the liquid flow in the horizontal direction to the three sections of the chamber system.
