Patent ID: 7617830

Claim:
An automated cleaning station to at least partially clean at least a portion of at least one appendage of a person using at least one fluid, comprising: a body; a rotatable wash chamber associated with the body, the wash chamber including a first end and a second end, the wash chamber including an axis of rotation; an appendage receiving cavity located within the wash chamber, the appendage receiving cavity adapted for being accessible by the portion of the at least one appendage through an opening in the first end of the wash chamber; a first set of nozzles disposed on the wash chamber in a ring configuration, the first set of nozzles located proximate to the first end of the wash chamber, wherein each nozzle of the first set nozzles is adapted to produce a spray that is projected at a pitch angle of between 15 and 35 degrees and at a roll angle of substantially 0 degrees; a second set of nozzles disposed on the wash chamber in a helical pattern along a length of the wash chamber, the second set of nozzles including a first nozzle located proximate to the opening in the first end of the wash chamber, wherein each nozzle of the second set of nozzles is adapted to produce a spray pattern that is projected at a pitch angle of substantially 0 degrees, wherein a first spray pattern associated with the first nozzle is projected at a first roll angle, wherein a second spray pattern associated with a second nozzle of the second set of nozzles is projected at a second roll angle, the second roll angle being different from the first roll angle, and wherein a remainder of the second set of nozzles each have a corresponding spray pattern oriented at progressively greater roll angles; at least one off-helix nozzle disposed on the wash chamber; whereby the first and second sets of nozzles, and the at least one off-helix nozzle are operable to receive the at least one fluid and to project the fluid into the appendage receiving cavity.
