Abstract

The fill opening extending through a sidewall of a plastic dishwasher tub is sealed with respect to an interconnecting fill funnel while splash-out and spray-out through the fill funnel are substantially eliminated. The fill funnel comprises a unipartite, plastic construction which is secured to the exterior surface of a plastic tub sidewall by fasteners extending through the funnel and into mounting bosses on the tub wall but terminating short of the inner tub surface to eliminate any fastener sealing requirement. The fill funnel includes a short, cylindrical conduit extending through the fill opening which includes an integral, diametral rib whose lower horizontal surface lies within the normal splash-out and spray-out paths intersecting the fill opening.

Claims

1. A dishwasher including a unipartite tub defining a wash chamber said tub having a fill opening in a sidewall thereof and bosses integral with said tub and spaced from said fill opening;

spray means contained within said tub positioned below the level of said fill opening said spray means introducing an upwardly directed liquid spray path intersecting said fill opening at an acute angle relative to said sidewall;

a door adapted to close said tub, said door having a generally vertically closed position;

a fill funnel mounted on an exterior surface of said tub in flow communication with said fill opening to admit water to Said wash chamber, said fill funnel including mounting sockets receivable by said bosses of said tub and baffle means positioned within the confines of said fill opening in intersection relation to said spray path.

2. The dishwasher of claim 1 wherein said fill funnel additionally includes a liquid flow conduit extending through said fill opening to terminate in a truncated open end lying substantially in the plane of said sidewall inner surface;

and said baffle means comprising a horizontally disposed rib integral with said liquid flow conduit.

3. The dishwasher of claim 2 wherein the lower surface of said rib lies within said spray path for deflecting a major fraction of the upwardly directed liquid spray entering the open end of said conduit.

4. The combination of claim 3 including seal means surrounding said fill opening and in sealing engagement with said exterior tub wall surface and the fill funnel.

5. The combination of claim 4 wherein said fill funnel is of unipartite plastic construction.
