DISHWASHER VENT CLOSING ARRANGEMENT 9D-DW-13146 ABSTRACT OF THE DISCLOSURE An arrangement for controlling communication of a dishwasher vent opening to allow escape of the humid air from the interior of the dishwasher cabinet during the drying cycle, while sealing the opening during the wash and rinse cycles, including a vertically aligned series of ribs mounted within the opening. Each rib is trough-shaped to provide a liquid retention channel and the bottom of each rib is posi- tioned within the next succeeding rib such that upon each channel being filled with water, a water seal of the opening is achieved. Alternate ends of each rib are open to create a cascade flow draining of the water through the rib series. The water level is maintained by being continuously replen- ished during the wash and rinse cycles to maintain the water seal. At the end of the rinse cycle, the water drains from the liquid retention channels to enable venting of the in- terior air through the ribs.
