A gas/liquid heat exchanger for cooling a hot gas has a plastic housing at least partly surrounding a metal core. The housing has separately formed inlet and outlet segments which may be formed from plastic materials having different heat resistance, and which are joined together along a sealed joint. One or both of the inlet and outlet segments are provided with bypass blocking element to at least partially blocks any gaps between the irregularly shaped sides of the core and the sides of the housing. Where the sides of the core include indentations, the bypass blocking elements may comprise a comb structure having fingers extending into the indentations. The housing is constructed to permit the core to be slidingly received into one or both of the inlet segment and the outlet segment of the housing.

A dishwasher, including a tub provided with a front lip, has a front door provided with alignment structure on an inner bottom portion which is designed to abut and deflect the front lip, when the front lip is bowed or otherwise deformed, to control the relative positioning between the door and the frontal lip in order to prevent the development of a leakage gap or undesirable engagement between the door and lip. The alignment feature preferably includes at least one cam rib located on the lower underside of the door, as well as adjacent abutment rib(s) adapted to extend toward the front lip of the tub when the door is opened. The cam rib functions to guide the lip along a smooth surface when the tub is bowed or otherwise significantly shifted from a design position to assure quiet shifting of the door, while the abutment rib functions to prevent the development of a potential leakage gap between the front lip and the door.

Tub lip alignment system for a dishwasher

A dishwasher includes a tub, a frame extending around the tub, and a door pivotally secured to the frame for movement between a vertical closed position and a horizontal open position. Hinges are provided on each side of the door to provide a door pivot axis, and are fixed to the frame of the dishwasher. The hinges are accurately positioned relative to the tub by providing at least one boss on each side of the tub, and a recess or hole in each hinge to receive the boss. The hinges are then secured to the frame with screws or by welding. Thus, the hinges are accurately aligned with one another at the proper location on the frame so as to provide proper sealing between the door and the tub when the door is in the closed position.

Dishwasher door hinge positioning means and method

A dishwasher tub is provided with containment structure which prevents liquid from leaking around a door seal. The containment structure includes a bead that extends along side portions of a front flange of the dishwasher tub. At each lower portion of the front flange, the bead includes an inward and downward extending portion which leads to a substantially vertical portion, and finally to another inward and downward extending portion. The final two portions of the bead are arranged along a reduced dimension section of the front flange and define a trough which guides the liquid back into the tub.

A single piece tub support and frame for a dishwasher has a unitary support member that includes a pair of laterally spaced U-shaped upright end portions and an intermediate inverted U-shaped upright portion. The intermediate portion fits over the top and sides of the dishwasher tub rearwardly adjacent the front flange portion thereof. When the U-shaped end portions clear the bottom wall of the tub, they resiliently spring inward into supporting positions under the bottom wall. The unitary support member greatly reduces the number of components required, reduces manufacturing time and cost, and maintains the tub in its designed shape.
