Abstract

A kitchenware washing assembly includes a tank for holding fluid for washing kitchenware, and at least one pump. The kitchenware washing assembly can also include at least one outlet chamber for dispensing fluid into the tank, and at least one intake chamber for receiving fluid from the tank. The kitchenware washing assembly may also include at least one intake cover for separating the intake chamber from the tank. The intake cover can include a plurality of inlets and at least one projection that extends into the tank. In addition, either or both of the outlet chamber and/or intake chamber can be configured to have positive drainage from the chamber into the tank. Further, the kitchenware washing assembly may include one or more detachable outlet covers configured to cover the outlet chamber. The detachable outlet cover can include a plurality of outlets for directing fluid into the tank.

Claims

1. A kitchenware washing assembly comprising a tank for holding fluid for washing kitchenware, at least one pump, at least one outlet for dispensing fluid into the tank, at least one intake chamber for receiving fluid from said tank, the intake chamber including at least a portion that is sloped to provide positive drainage along at least one inner surface within the intake chamber into the tank, and at least one intake cover for separating the intake chamber from the tank, said intake cover including a plurality of inlets and a projection extending into the tank, the projection configured to inhibit kitchenware from being drawn up flush against the inlets of the intake cover.

2. The assembly of claim 1, wherein said projection extends across a substantial portion of the intake cover.

3. The assembly of claim 1, wherein the intake cover includes a plurality of projections extending into the tank.

4. The assembly of claim 1, wherein the projection is a rib that generally extends from a first side of the intake cover to a second side of the intake cover.

5. The assembly of claim 4, wherein the rib includes at least a portion of the inlets.

6. The assembly of claim 1, wherein the projection has a generally V-shaped longitudinal cross-section.

7. The assembly of claim 1, wherein the intake cover is detachable from said tank and said intake chamber.

8. The assembly of claim 1, wherein the inlets are patterned to substantially distribute the flow of intake fluid across the intake cover.

9. The assembly of claim 1, wherein the inlets are patterned to substantially evenly distribute the intake fluid pressure across a length of the intake cover.

10. The assembly of claim 9, wherein the inlets are patterned such that more material mass of the intake cover is distributed in front of a fluid conduit connecting the pump to the intake chamber.

11. The assembly of claim 1, wherein at least a portion of the inlets are adjacent the bottom of the intake chamber thereby allowing fluid flowing along the at least one inner surface to drain from the intake chamber into the tank.

12. The assembly of claim 1, wherein the intake cover is oriented at an angle above horizontal.

13. The assembly of claim 1, wherein the intake cover is oriented at an angle of about forty-five degrees or more above horizontal.

14. The assembly of claim 1, wherein the intake cover is oriented substantially vertically.

15. The assembly of claim 1, wherein the intake cover is positioned to be substantially submerged by fluid in the tank during operation of the assembly.

16. The assembly of claim 1, comprising at least one side wall defining at least a portion of the tank, the intake cover being attached to the tank in a substantially parallel configuration with the at least one side wall.

17. A kitchenware washing assembly comprising a tank for holding fluid for washing kitchenware, at least one pump, at least one inlet for receiving fluid from said tank, at least one outlet chamber on at least one wall of the tank for dispensing fluid into the tank, a resilient sealing member, and a plurality of detachable outlet covers each configured to cover the outlet chamber and each having a plurality of outlets forming a different pattern from the other detachable covers, and after being detached, each of the detachable outlet covers being readily reattachable by mechanical fasteners for covering the outlet chamber, wherein the resilient sealing member is positioned to provide a fluid tight seal between the outlet cover and at least one of the tank and the outlet chamber, whereby flow patterns of fluid into the tank may be selectively changed for different washing operations by selecting which of the interchangeable outlet covers is used for covering the outlet chamber.
