The present disclosure relates generally to dishwasher appliances and to racks for holding dishware and cutlery for a dishwasher. More particularly, the present disclosure relates to a third or top washware rack that is made out of wire and that has greater spacing between an upper surface of a deepest portion of the top washware rack and an inner surface of a top wall of the dishwashing compartment.
In general, most domestic dishwashers include two dishware racks to support items to be washed such as dishware, glassware, kitchen utensils, pots, pans, and the like. Typically, the two dishware racks include an upper dishware rack positioned near a top portion of the dishwasher, and a lower dishware rack arranged below the upper dishware rack. The upper dishware rack is used to support glassware, utensils, and other small items, while the lower dishware rack is used to support larger items, such as dinner plates, large bowls, cooking sheets, and baking pans. The dishware racks are normally formed from several discrete lengths of wire, welded together and then covered with a rubber or a plastic coating. Further, the dishware racks are formed with a plurality of vertically projecting tines to support and organize the items placed on the dishware rack.
Moreover, the use of a third, top washware rack is known per se in household dishwasher appliances. Such a third, top washware rack is positioned immediately above a second or middle washware rack. The second, middle washware rack is in turn positioned above a first or bottom washware rack that normally hold lager items, such as large dinner plates, etc., as noted above, inside the dishwashing compartment.
However, the known third, top washware racks are limited in their capacity, flexibility, and versatility.
More specifically, the known third, top washware racks have a large plastic insert piece that forms the basket of the rack and that is fitted over a wire frame. The wire frame is thus substantially hidden from view to the user by the plastic insert. The bulky plastic insert results in a relatively small clearance or spacing between an upper surface of a deepest portion of the top washware rack and an inner surface of a top wall of the dishwashing compartment, thereby limiting what can be placed on the third washware rack. Also, the bulky plastic insert that forms the basket of the third washware rack causes water to be retained and thus inhibits the drying performance of the dishwasher.
An apparatus consistent with the present disclosure is directed to a third, top washware rack that increases the dishwasher capacity, flexibility, and versatility, as well as enhancing the drying performance of the dishwasher.
An apparatus consistent with the present disclosure is directed to a third, top washware rack that is made out of wire and eliminates the bulky plastic insert. Thus, the third, top wire rack has a greater spacing between an upper surface of a deepest portion of the top washware rack and an inner surface of a top wall of the dishwashing compartment. Also, the third, top wire rack enhances the drying performance.
An apparatus consistent with the present disclosure is directed to a third, top washware rack that allows the dishwasher to accommodate specialty items such as stemmed wine glasses.
An apparatus consistent with the present disclosure is directed to a third, top washware rack that is configured to hold bowls at a slight tilt with respect to horizontal in order to drain off water from the bowls.
