Abstract

A wash cylinder or chamber for an automated cleaning station to clean an object or a person'"'"'s body part includes nozzles on the interior of the cylinder, the nozzles of one embodiment comprising an increasing roll angle providing a novel spray pattern. Additionally, embodiments of the invention include fluid guidance and conveyance structures, angled nozzles, sealing structures, finger guards, nozzle ribs, wash chamber seating mechanisms and drains, and nozzle inlays having a plurality of nozzles. Also disclosed are methods of washing an object or body part using a wash cylinder or chamber and methods of assembling a wash cylinder or chamber.

the inner member includes a cylinder portion and a frusto-conical portion, the frusto-conical portion including a flat surface and a sloped surface; and

wherein the outer member and the inner member are separate components that interconnect with each other to form the wash chamber.

3. The cleaning station of claim 2, wherein the recessed portion includees a first substantially rectangular portion and a second substantially rectangutar portion, the first rectangular portion having a first width and the second rectangular portion having a second width, the first width being less than the second width, wherein the nozzle inlay having a first substantially rectangular section adapted to be received in the first substantially rectangular portion of the recessed portion, and the nozzle inlay having a second substantially rectangular section adapted to be received in the second substantially rectangular portion of the recessed portion.

4. The cleaning station of claim 3, wherein the nozzle inlay includes an inlet side and an outlet side, wherein the outlet side is flush with the first surface of the inner member.

5. The cleaning station of claim 4, wherein the recessed portion is oriented parallel to the opening of the first end of the body and is disposed proximate to the first end of the body, and wherein the plurality of nozzles associated with the nozzle inlay project fluid at an angle between about 10 and about 30 degrees with respect to a normal to the first surface.

6. The cleaning station of claim 5, wherein the nozzle inlay includes four nozzles.

7. The cleaning station of claim 4, wherein the recessed portion is oriented in a helix along a length of the inner member, and wherein the nozzles associated with the nozzle inlay project fluid at progressively steeper roll angles.

8. The station of claim 1, wherein at least two of the plurality of nozzles have different pitch angles.

9. The station of claim 1, wherein at least two of the plurality of nozzles have different roll angles.

10. A cleaning station, comprising:

a rotatable wash chamber, the wash chamber including a first end and a second end;

an appendage receiving cavity located within the wash chamber, the appendage receiving cavity adapted for being accessible by at least a portion of at least one appendage of a user through an opening in the first end of the wash chamber; and

a nozzle inlay including a plurality of interconnected nozzles, the nozzle inlay being removably interconnected to the wash chamber, the plurality of nozzles being adapted to receive at least one fluid and to project the fluid into the appendage receiving cavity to at least partially clean the at least a portion of the at least one appendage of a person using the at least one fluid.

11. The cleaning station of claim 10, wherein the nozzle inlay is connectable to a recessed portion of the wash chamber, the recessed portion including a first substantially rectangular portion and a second substantially rectangular portion, the first rectangular portion having a first width and the second rectangular portion having a second width, the first width being less than the second width, the nozzle inlay having a first substantially rectangular section adapted to be removably received in the first substantially rectangular portion of the recessed portion, and the nozzle inlay having a second substantially rectangular section adapted to be removably received in the second substantially rectangular portion of the recessed portion.

12. The cleaning station of claim 11, wherein the recessed portion is oriented paraltel to the opening of the first end of the wash chamber and is disposed proximate to the first end of the wash chamber, and wherein the plurality of nozzles associated with the nozzle inlay project fluid at an angle between about 10 and about 30 degrees with respect to the surface of the wash chamber.

13. The cleaning station of claim 10, wherein the nozzle inlay includes an inlet side and an outlet side, wherein the outlet side is flush with a surface of the wash chamber.

14. The cleaning station of claim 10, wherein the wash chamber includes an inner body member and an outer body member.

15. The station of claim 10, wherein at least two of the plurality of nozzles have different pitch angles.

16. The station of claim 10, wherein at least two of the plurality of nozzles have different roll angles.
