Abstract
In a drawer-style washing appliance, such as a drawer-style dishwasher 100, a tub flange 301 is provided with drainage-facilitating features 167 to encourage draining of any pooled washing liquid on the upper surface of the tub flange during a washing cycle, which would otherwise remain there after opening of the drawer. The drainage features may be one or more ridge 168 or channel on/in the surface of the tub flange, particularly at or about the inner peripheral edge 304 of the tub flange. Alternatively, the drainage-facilitating features may be provided on the underside of the tub lid 201 in a region that will come into contact with the tub flange when the lid is lowered to seal the tub during a washing cycle.

- a seal-contacting side, opposite to and spaced away from the attachment side, including a planar region adapted to be contacted by a lid seal for closing the washing tub during a washing cycle of the appliance,
- a peripheral wall, extending from the seal-attachment side toward the attachment side, forming an opening of the washing tub at a peripheral edge between the peripheral wall and the planar region of the seal-attachment side, and
- at least one drainage ridge or channel on or in the peripheral wall and/or the seal-contacting side, at least in the region of the peripheral edge, for channelling liquid from the seal-contacting side to the peripheral wall.
