| 20100139719 | DISHWASHER HAVING MULTI-MODE SPRAY ARM SYSTEM - A spray assembly for an automatic dishwasher is provided comprising a conduit system for receiving pressurized washing liquid, and an elongated spray arm including an upper surface and a lower surface. The spray arm includes a dividing wall between the upper surface and the lower surface. The spray arm includes a plurality of orifices formed in the upper surface and the lower surface for distributing the liquid throughout the dishwasher. The dividing wall and the upper surface define an upper interior compartment and the dividing wall and the lower surface define a lower interior compartment. The conduit includes a water feed system and a water diverting mechanism for selectively diverting water into the upper compartment, the lower compartment, or both the upper and the lower compartments. | 06-10-2010 |
| 20100314977 | ADJUSTABLE UPPER DISHWASHER RACK - An upper rack vertical adjustment system for a dishwasher, including an upper rack first portion, and an upper rack second portion rotatably attached to the first portion to selectively create an opening in the bottom of the rack to provide clearance for items placed in the lower rack. For adjusting the height of the upper rack, a slidable member has two elongated arms extending therefrom each having a wheel attached at an end of the arms is provided on each side of the rack. For each slidable member, a plate is mounted to a portion of the upper rack and the said slidable member is pivotally mounted to the plate.

| 20110000510 | DISHWASHER STEAM ALGORITHM - A dishwasher having a washing chamber includes at least one prewash cycle for removing loose soil from associated kitchenware, a steam cycle instituted after the at least one prewash cycle for softening soil not removed in the at least one prewash cycle, a main wash cycle commenced after the steam cycle cleaning the associated kitchenware, and at least one rinse cycle commenced subsequent to the main wash cycle for rinsing detergent and remaining soil off of the associated kitchenware. The dishwasher includes a housing having a wash chamber that receives associated kitchenware therein and a controller for selectively controlling water supply from an associated source, water removal to an associated drain, and energization of a heating element contained in the wash chamber. A wash routine having a pulse routine periodically introduces wash fluid into the wash chamber to wet an inner surface of the chamber and the associated kitchenware received therein and a steam routine in which the wash fluid is retained in the wash chamber and the heating element remains energized to generate steam in the wash chamber environment by droplets of the wash fluid contacting exposed surface portions of the heating element. | 01-06-2011 |
| 20110030729 | AUTOMATIC AND MANUAL DETERGENT TYPE IDENTIFICATION TO SELECT A WASH ALGORITHM BASED ON DETERGENT TYPE - A detergent module for dispensing detergent during a wash-cycle is presented in which a sensor senses and indicates or a user via control input indicates whether the detergent in the module is a solid-type detergent or a liquid-type detergent, and the detergent-type indication is used by a dishwashing machine or a laundry washing machine to select a washing algorithm tailored to exploit the cleaning efficiency of the detergent. | 02-10-2011 |
