Problems solved by technology

[0003] Traditional spray arm systems, while simple and most effective, have the disadvantage that they must spread the wash liquid evenly over all areas to achieve satisfactory results
Doing so often wastes resources such as time, energy, and water because the wash solution cannot be concentrated exactly where it is needed
Additionally, because the spray arms follow a generally circular path, the corners of the bucket may not be fully covered, resulting in lower cleaning performance for utensils located in the corners of the rack
Additionally, in some cases, during at least part of the rotation, the spray port of the spray arm can be aimed at the side of the wash tub, causing unwanted noise during the wash cycle

Embodiment Construction

[0049] In some embodiments according to the invention, the one or more conduits supported by the dishwasher rack may selectively interface with a wall-mounted docking device comprising multiple and / or swivel docking ports, And optionally includes a check valve and / or diverter valve integrated with each docking port, and a return mechanism for biasing each conduit to a predetermined rotational position.

[0050] In this regard, a conduit may be considered a body capable of conveying a fluid, such as water, a washing liquid including water, a detergent and / or another treatment component, or compressed air. In some embodiments, the conduit may deliver fluid to one or more jetting elements supported by the stent, while in other embodiments the conduit itself may include one or more holes or nozzles such that the conduit also serves as the jetting element to spray fluid onto the utensils in the wash tub. One particular type of conduit used in some embodiments of the present invent...

Abstract

A dishwasher (10, 250) and method for operating the same utilizing a shelf-mounted rotatable conduit having a return mechanism (562, 584) that When the docking arrangement (302, 400, 500) on the wall (234) of the barrel (16, 252) is disconnected, the return mechanism positions the rotatable conduit to a predetermined rotational position.

Description

technical field [0001] The present invention relates to a dishwasher with a rack-mounted conduit return mechanism. Background technique [0002] Dishwashers are used in many single-family and multi-family residential applications for cleaning dishes, silverware, cutlery, cups, glasses, pots, pans, etc. (collectively referred to herein as "ware"). Many dishwashers rely primarily on rotatable spray arms disposed on the bottom and / or top of the tub and / or mounted on racks of the container. A spray arm is coupled to a source of washer fluid and includes a plurality of holes for spraying washer fluid onto the utensils, and generally rotates about a central hub such that each hole follows a circular path during rotation of the spray arm. The holes can also be angled so that the force of the wash liquid exiting the spray arm causes the spray arm to rotate about the central hub. [0003] Traditional spray arm systems, while simple and the most effective, have the disadvantage that...
