Abstract

An exemplary kitchenware washing assembly generally includes a tank for holding fluid for washing kitchenware. The assembly also includes at least one pump for agitating the fluid in the tank. The at least one pump is configured with at least one drain to allow at least some fluid to drain from the at least one pump.

Claims

1. A kitchenware washing assembly comprising a tank for holding fluid for washing kitchenware, and at least one pump for agitating the fluid in the tank, wherein the at least one pump is configured with at least one drain at about a low point of the at least one pump to allow drainage of the fluid from the at least one pump.

2. The assembly of claim 1, wherein the at least one pump includes at least one outlet coupled in fluid communication with at least one outlet of the assembly for dispensing fluid into the tank.

3. The assembly of claim 1, wherein the at least one pump comprises two pumps.

4. The assembly of claim 3, further comprising at least one valve coupled to the at least one drain of the two pumps such that the at least one valve is operable for opening and closing the at least one drain of the two pumps.

5. The assembly of claim 3, wherein the tank includes at least one drain, and wherein the assembly further comprises an actuator configured for opening and closing both the at least one drain of the tank and the at least one drain of the two pumps.

6. The assembly of claim 1, wherein the tank includes at least one drain, and wherein the assembly further comprises an actuator configured for opening and closing both the at least one drain of the tank and the at least one drain of the pump.

7. The assembly of claim 1, wherein the at least one drain is configured to allow drainage of the fluid from the at least one pump solely via gravity.

8. The assembly of claim 1, wherein the at least one drain is configured to allow drainage of substantially all of the fluid from the at least one pump solely via gravity.

9. A kitchenware washing assembly comprising a tank for holding fluid for washing kitchenware, and at least one pump for agitating the fluid in the tank, wherein the at least one pump is configured with at least one drain to allow at least some fluid to drain from the at least one pump.

10. The assembly of claim 9, wherein the at least one drain is at about at about a low point of the at least one pump to allow drainage of substantially all of the fluid from the at least one pump solely via gravity.

11. The assembly of claim 9, wherein the at least one pump includes at least one outlet coupled in fluid communication with at least one outlet of the assembly for dispensing fluid into the tank.

12. A kitchenware washing assembly comprising a tank for holding fluid for washing kitchenware, and at least one pump for agitating the fluid in the tank, wherein the at least one pump and the tank are connected by at least one fluid passage, and wherein the at least one fluid passage is configured with at least one drain at about a low point of the at least one fluid passage to allow drainage of the fluid from the at least one pump and the at least one fluid passage.

13. In a kitchenware washing assembly having a tank for holding fluid for washing kitchenware, and at least one pump for agitating the fluid within the tank, the improvement comprising at least one drain at about a low point of the at least one pump to thereby allow drainage of the fluid from the at least one pump.

14. In a kitchenware washing assembly having a tank for holding fluid for washing kitchenware, at least one pump for agitating the fluid within the tank, and at least one fluid passage connecting the at least one pump and the tank, the improvement comprising at least one drain at about a low point of the at least one fluid passage to thereby allow drainage of the fluid from the at least one pump and the at least one fluid passage.

15. A method of draining fluid from at least one pump of a kitchenware washing assembly, the kitchenware washing assembly including a tank for holding fluid for washing kitchenware and at least one pump for agitating the fluid within the tank, the method comprising opening at least one drain at about a low of the at least one pump such that the fluid drains from the at least one pump through the open drain.

16. The method of claim 15, further comprising closing the at least one drain.

17. The method of claim 15, wherein opening at least one drain comprises opening at least one valve coupled to the at least one drain.

18. The method of claim 17, wherein opening at least one valve comprises manually opening the at least one valve.

19. The method of claim 17, wherein opening the at least one valve comprises automatically opening the at least one valve without manual intervention.

20. The method of claim 19, wherein automatically opening includes activating at least one solenoid coupled to the at least one valve.

21. The method of claim 15, wherein the tank includes at least one drain, and wherein the method includes substantially simultaneously opening both the at least one drain of the tank and the at least one drain of the at least one pump.

22. The method of claim 15, wherein the tank includes at least one drain, and wherein the method comprises opening the at least one drain of the tank and the at least one drain of the at least one pump with a single actuator.

23. The method of claim 22, further comprising closing the at least one drain of the tank and the at least one drain of the at least one pump with a single reverse actuation of the actuator.

24. The method of claim 15, wherein the at least one pump comprises two pumps, and wherein opening the at least one drain comprises opening at least one valve coupled to the at least one drain of the two pumps.

25. The method of claim 15, wherein the at least one pump comprises two pumps, and wherein opening the at least one drain comprises substantially simultaneously opening the at least one drain of each said pump.

26. The method of claim 15, further comprising:

monitoring washing cycles to detect an indicator that the fluid for washing kitchenware should be replaced;

after detecting the indicator that the fluid for washing kitchenware should be replaced, deactivating the at least one pump; and

opening the at least one drain.

27. The method of claim 15, further comprising:

counting a number of washing cycles since a replacement of the fluid for washing kitchenware;

comparing the counted number of washing cycles to a preset value;

if the counted number of washing cycles is equal to or exceeds the preset value, deactivating the at least one pump; and

opening the at least one drain.

28. The method of claim 27, further comprising allowing an operator to input the preset value.

29. A method of draining fluid from at least one pump of a kitchenware washing assembly, the kitchenware washing assembly including a tank for holding fluid for washing kitchenware, at least one pump for agitating the fluid within the tank, and at least one fluid passage connecting the at least one pump and the tank, the method comprising opening at least one drain at about a low of the at least one fluid passage such that the fluid drains from the at least one pump and the at least one fluid passage through the open drain.

30. A method of assembling a kitchenware washing assembly, the kitchenware washing assembly including a tank for holding fluid for washing kitchenware, at least one outlet for dispensing fluid into the tank, at least one inlet for receiving fluid from the tank, and at least one pump for pumping fluid from the at least one inlet to the at least one outlet, the method comprising positioning the at least one pump such that at least one drain thereof is at about a low point of the at least one pump, to thereby allow drainage of fluid for washing kitchenware from the at least one pump.

31. The method of claim 30, further comprising coupling the at least one drain to at least one valve such that the at least one valve is operable for opening and closing the at least one drain.

32. The method of claim 30, wherein the at least one pump comprises two pumps.

33. The method of claim 32, further comprising coupling the at least one drain of each said pump to the same valve such that the valve is operable for opening and closing the at least one drain of each said pump.

34. The method of claim 30, wherein the tank includes at least one drain, and wherein the method comprises coupling the at least one drain of the tank and the at least one drain of the at least one pump to the same actuator for opening and closing the drains.
