Turbulent Flow Washing Apparatus and Method
Methods and apparatus utilizing turbulent fluid flow to wash soiled items. A washing chamber ( 2 ) is connected to a pump ( 10 ) and contains a baffle ( 5 ) that divides or partially divides the chamber ( 2 ). The baffle ( 5 ) contains one or more openings ( 12 ) through which fluid surges in response to pressure generated by the pump ( 10 ). By using a reciprocating piston or diaphragm-type pump, back-and-forth fluid flow is generated. The fluid turbulence created by the fluid surging through the baffle openings creates a “scrubbing action” upon the surface of the items being washed.
1 . A method for washing an item, comprising the steps of:
(a) securing said item into an enclosed chamber that is divided by a baffle, wherein said baffle contains at least one opening therethrough; and
(b) circulating a fluid through said chamber such that the fluid flows back-and-forth through said at least one opening of the baffle, thereby generating a turbulent fluid flow over an exterior of said item.
2 . The method of claim 1 , wherein said chamber is pressurized.
3 . (canceled)
4 . The method of claim 1 , wherein said item is placed within said enclosed chamber such that it is not in contact with said at least one opening in said baffle.
5 . A method for washing an item, comprising the steps of:
(a) securing said item into an enclosed chamber that is partially divided by a baffle, wherein said baffle contains at least one opening therethrough; and
(b) circulating a fluid through said chamber such that the fluid flows back-and-forth through said at least one opening of the baffle, thereby generating a turbulent fluid flow over an exterior of said item.
6 . The method of claim 5 , wherein said chamber is pressurized.
7 . (canceled)
8 . The method of claim 5 , wherein said item is placed within said enclosed chamber such that it is not in contact with said at least one opening of said baffle.
9 . An apparatus for cleaning an item, comprising:
(a) an enclosed chamber divided by a baffle, wherein said baffle contains at least one opening therethrough,
(b) a means for securing said item within said chamber; and
(c) a pumping means in fluid connection with said chamber, wherein a back-and-forth turbulent fluid flow is produced over an exterior of said item as a result of fluid flowing through said at least one opening of the baffle.
10 . The apparatus of claim 9 , wherein said pumping means includes a diaphragm.
11 . The apparatus of claim 9 , wherein said enclosed chamber contains at least one rack.
12 . (canceled)
13 . The apparatus of claim 9 , wherein said enclosed chamber is pressurized.
14 . The apparatus of claim 9 , wherein said at least one opening of said baffle transversely varies in diameter.
15 . The apparatus of claim 9 , wherein said baffle contains two or more openings.
16 . The apparatus of claim 9 , wherein said baffle contains two or more openings of different diameters.
17 . An apparatus for cleaning an item, comprising:
(a) an enclosed chamber partially divided by a baffle, wherein said baffle contains at least one opening therethrough,
(b) a means for securing said item within said chamber; and
(c) a pumping means in fluid connection with said enclosed chamber, wherein a back-and-forth turbulent fluid flow is produced over an exterior of said item as a result of fluid flowing through said at least one opening of the baffle.
18 . The apparatus of claim 17 , wherein said pumping means includes a diaphragm.
19 . The apparatus of claim 17 , wherein said enclosed chamber contains at least one rack.
20 . (canceled)
21 . The apparatus of claim 17 , wherein said enclosed chamber is pressurized.
22 . The apparatus of claim 17 , wherein said at least one opening of said baffle transversely varies in diameter.
23 . The apparatus of claim 17 , wherein said baffle contains two or more openings.
24 . The apparatus of claim 17 , wherein said baffle contains two or more openings of different diameters.
25 . A cleaning system, comprising:
(a) an enclosed chamber, said enclosed chamber being at least partially divided by a baffle containing at least one opening therethrough,
(b) an item to be cleaned secured within said enclosed chamber and free of contact with said baffle and;
(c) a pumping means in fluid connection with said enclosed chamber, wherein a back-and-forth turbulent fluid flow is produced over an exterior of said item as a result of fluid flowing through said at least one opening of the baffle.
