    摘要： A dishwasher operates to sense the need for a drain or purge operation based on dynamic characteristics of a respective washing operation such that an adaptive system is defined. In accordance with the invention, washing fluid used to spray clean kitchenware being washed is filtered and soil from the kitchenware is collected. When the filtering system becomes clogged, a flow signal is established to indicate the need for at least a partial drain operation. Most preferably, this arrangement is used in combination with signals from a turbidity sensor, as well as pump motor current signals, to provide an comprehensive, dynamically adaptive control system.

    摘要： A washing tub is formed with a reinforcing body made from a non-metallic material, such as plastic or fiberglass, and a thin interior liner portion constituted by a metallic material, preferably stainless steel. The metallic material is preferably sprayed onto a tub shaping member and then the reinforcing body is attached to the metallic material. In accordance with one embodiment of the invention, the reinforcing body is formed from plastic, such as polypropylene, which is injected about a mold core following the spray coating of the metallic material on the core. In another embodiment, the reinforcing material is constituted by fiberglass which is layered about a shaping member having the metallic liner portion deposited thereon. In any case, an aesthetically appealing and extremely cost effective, high quality washing tub is produced.

    摘要： The present invention relates to a vent seal device for an automatic dishwasher. The dishwasher includes a door having a vent opening therein. An elongated flexible strip is mounted in the door adjacent and generally registered with the vent opening. The strip has opposite ends and a central portion therebetween. At least one end of the strip is secured against movement with respect to the frame. During certain times of the wash and rinse cycles the strip is deflected into sealing engagement with the vent opening, thereby closing the normally open vent opening.

    摘要： A one-piece wash arm is provided for a dishwasher. The wash arm has an open channel through which water from a water supply hose is directed. The channel has opposite curved ends with discharge openings through which the water is sprayed onto objects to be washed in the dishwasher. The flow of water through the channel and the curved ends imparts rotation to the wash arm. In a preferred embodiment, the open channel is downwardly facing, and the water is substantially maintained in the channel due to the water pressure, velocity and surface tension. In an alternative embodiment, the open channel is directed upwardly.

    摘要： A dishwasher includes a pump assembly having a chopper blade and apertured plate arrangement which function to chop soil particles entrained in a flow of washing fluid. The chopper blade floats or axially slides relative to a drive member from a first position spaced from the apertured plate to a second position closer to the apertured plate in order to macerate the soil particles. The chopper blade is actually mounted to a hub member including a shaft portion that extends into and abuts an inner portion of an impeller to maintain a desired spacing between the chopper blade and the apertured plate, while transferring drive from the drive member to both the chopper blade and impeller.
