Silverware, flatware or parts washer apparatus and method thereof
An apparatus and a method of washing (or pre-washing) silverware/flatware, or one or more other objects/parts is provided. The apparatus and method utilizes a fluid-push/pull pumping system and method in which generally an entire volume of fluid is pushed or pulled through a cavity of a housing in which the silverware/flatware or other objects/parts are located. The housing is configured to hold a mass of silverware or other item(s) within the cavity. The pumping system, which includes manifolding in fluid communication with the cavity, is configured to pump generally an entire volume of fluid out of the cavity, and to direct the pumped fluid back into the cavity to create a generally continuous flow of generally an entire volume of fluid through the cavity, thereby causing the fluid to flow through the mass of silverware or other item(s).
1. A fluid circulating system for washing items, the system comprising:
a housing;
a cavity for locating silverware, flatware or one or more other items during operation, said cavity positioned within said housing; and
a pumping system including a manifolding in fluid communication with said cavity of said housing, said manifolding being associated with an opening at a first location in association with said cavity;
wherein said manifolding defines a fluid path extending at least from said opening, around said cavity, to another location of said cavity differing from said first location; and
wherein said pumping system creates a generally continuous flow of fluid across substantially an entire cross section of said cavity, such that fluid is caused to flow between items located within said cavity.
2. The fluid circulating system as claimed in claim 1 wherein said fluid path creates a generally continuous flow of fluid through generally the entire volume of said cavity.
3. The fluid circulating system as claimed in claim 1 wherein said manifolding includes a lower portion and an upper portion, and wherein the fluid path extending around said cavity includes the path extending from said opening to a lower portion of said manifolding, then to an upper portion of said manifolding, and then to said another location of said cavity differing from said first location.
4. The fluid circulating system as claimed in claim 1 wherein said opening is an intake port to pull fluid from said cavity.
5. The fluid circulating system as claimed in claim 1 wherein said opening is an outlet port to push fluid into said cavity.
6. The fluid circulating system as claimed in claim 1 wherein said pumping system oscillates from a forward direction to a reverse direction during operation to either push fluid into or pull fluid out of said cavity through said opening.
7. The fluid circulating system as claimed in claim 3 wherein said opening generally extends across an entire bottom area of an end of said cavity, and wherein said another location is an opening in the top of said cavity.
8. The fluid circulating system as claimed in claim 1 further comprising a flow control structure.
9. The fluid circulating system as claimed in claim 1 wherein said cavity is removable from said housing.
10. The fluid circulating system as claimed in claim 1 wherein said pumping system comprises a propeller that generally extends across an entire area of said opening.
11. The fluid circulating system as claimed in claim 1 wherein said opening comprises multiple openings.
12. The fluid circulating system as claimed in claim 1 further comprising a web connecting said cavity and said housing.
13. The fluid circulating system as claimed in claim 1 wherein said manifolding is formed at least in part by a wall of said housing, wherein said manifolding is formed at least in part by a wall of said cavity.
14. The fluid circulating system as claimed in claim 1 wherein said pumping system comprises a centrifugal impeller-type pump.
15. The fluid circulating system as claimed in claim 1 wherein said pumping system comprises a propeller-type pump.
16. The fluid circulating system as claimed in claim 1 further comprising a removable rack within said cavity.
17. The fluid circulating system as claimed in claim 1 wherein said cavity includes one or more openings to allow fluid to flow between said cavity and said manifolding.
18. The fluid circulating system as claimed in claim 17 wherein said one or more openings are located toward an upper portion of said cavity.
19. The fluid circulating system as claimed in claim 18 wherein one or more openings include additional openings that are located toward a lower portion of said cavity.
20. The fluid circulating system as claimed in claim 19 wherein said one or more additional openings toward said lower portion of said cavity have a lower opening density than said one or more openings located toward said upper portion of said cavity.
