- FIGURE 1 is a side View of the fruit and Vegetable washing device properly positioned beneath an open water faucet.
- the arrows indicate the flow path of the circulative liquid flow.
- FIGURE 2 is a plan view of FIGURE 1 showing the comparativelynarrow width, W of the washing device,
- FIGURE 3 is a section along line 3--3 of FIGURE 1 showing, to a larger scale, the typical cross-section of a food unit defiector and liquid guide vane.
- the prior art has provided a narrow two dimensional washing device of the present type, as for example that described in copending application of Serial No. 246,- 715 filed Dec. 24, 1962, now Patent No. 3,208,732.
- That configuration includes a cover specific means for liquid exhaust flow.
- the cover element thereof is effective and functions to provide important advantages as described therein.
- a principal purpose of the present invention is to contribute materially to the preservation of and even to the generation of contained flow which is two dimensional, and hence of ncreased efiicicncy. This allows operation of the device at lower available water pressures, or for the cleaning of larger loads of food units at a given water pressure.
- washing device l is comprised of side walls 2 and 3 extending longitudinally and vertically and spaced apart in relative proximity.
- a lateral wall 4 extends between side walls 2 and 3 to provide a bottom wall 5 and two opposite end walls 6 and 7.
- the bottom wall 5 and end wall 6 are faired together by radius R to provide a curved inner surface, as shown.
- the liquid inlet unit 8 is comprised of a vertically extending duct portion 9, an upper inlet port 10 open upwardly to the atmosphere, and lower exit port 11 which is submerged below normal liquid Operating level.
- Exit port 11 is of elongated cross-section, wherein the major axis is perpendicular to the plane of end wall 6.
- Inlet port 10 is circular and oversize, and duct portion 9 tapers downwardly to elongated exit port 11.
- Inlet unit 8 is fastened to end wall 6 by clip 12.
- the washing device, in service, is postioned under open faucet 13, as shown in FIGURE 1 so that free water jet 14 is in line with inlet port 10. This establshes vetical circulative flow within the device as indicated by the arrows in FIG- URE 1.
- the present device When the width of the device becomes relatively large with respect to the length or height the circulative two dimensional flow pattern is not obtained, but localized random liquid agitation occurs at the region of faucet water entry element which provides liquid flow whereby kinetic energy is more fully conserved in order to do the useful work of forcing the contained food units to revolve with the contained liquid.
- the present device will function to wash a larger load of food units at one time. Also, the present device will function more eflectively at those times of the day when the available water pressure is low, and in second floor apartments, etc., where the available water pressure may be relatively low.
- Closure portion 15 is in three cooperating portions, which may be used separately or in combination.
- Center closure portion 16 is bonded along line 17 to liquid deflector portion 18, and along line 19 to food unit deflector portion 20.
- Liquid deflector portion 18, center closure portion 16, and food unit deflector portion 20 ⁇ function simultaneously to contribute to the preservation of the two dimensional liquid flow within the container.
- Their combined results are more than the sum of their separate results, since lateral flow deviations are continuously suppressed by each of the three portions. The omission of any portion would command a greater restoring effort from the remaining portions which would therefore be less eflicient due to stronger liquid cross flows and eddies.
- Liquid exhaust occurs through the plurality of narrow, elongated slots 21 in center closure portion 16'.
- the flow is up through slots 21 in a plurality of thin parallel streams.
- Exhaust liquid forms in a thin sheet on the upper surface of center closure portion 16 and flows outwardly to the two edges, and from there runs overboard to the floor of the snk.
- exhaust flow from the container is two dimensional and does not induce cross currents within the container. This aids in preserving two dimensional flow within the container.
- Liquid deflector portion 18 is of curved, solid form to deflect both the food units and liquid. Clearances a and b, in FIGURE 2, exist between the closure portion and the walls of device 1. To prevent the flow of liquid through the gaps of clearances a and b, side walls 2 and 3 and end wall 7 are extended locally to upper edges 21A which are of higher elevation than upper edges 22 at the center portion of side walls 2 and 3 to provide three sides of an elevated reservoir.
- Liquid deflector portions 18 includes an integral transverse rib 23 which extends through notches 24 and 25 in side walls 2 and 3 and provides the fourth side of the reservoir. The rib 23 provides a secondary seal and also holds deflector portion 18 in position when the bond at line 17 is omitted.
- Volume A of the eleva-ted reservoir fills with liquid almost to the elevation of upper edge 21A.
- the water level of volu-me A may -be of an inch greater than that of other liquid in the containeror in the cover slots 21.
- the liquid in Volume A stagnates and there is no noticeable flow 'between clearances a and b in normal operation.
- Liquid deflector portion 18 and the static water reservoir function to turn all liquid without leakage. This assures symmetrical flow at the critical turn region and reduces cross flows and eddies and results in important conservaton of kinetic energy.
- Food unit deflector portion 20 ⁇ is comprised of a plurality of deflector vanes 26 cantilevered from support 27. Tabs 28 and 29 extend downwardly from support 27 to externally grip side walls 2. and 3 by a friction fit.
- deflector portion 20 may not be bonded to center closure portion 16 along line 19, in which case tabs 28 and 29 may be bonded to walls 2 and 3 to provide fixed support for deflector vanes 26.
- Deflector vanes 26 are spaced parallel, and a cross-section of one vane is shown typically in FIGURE 3 to enlarged scale.
- contained liquid flow is through the compartment of Volume B, where inlet unit 8 is located.
- Two dimensional liquid flow is stabilized locally by vanes 26. This provides for a more efiicient union of the flow of the contained liquid and the flow of the inlet jet from inlet unit 8.
- a more eflicient mixing of flows occurs with less turbulence and eddies, and with greater conservaton of kinetic energy.
- Upper edges 30 of the walls 2, 3, and 6 above vanes 26 are at a higher elevation than the upper surface of center closure portion 16 to prevent the exhaust of contained liquid from Volume B above vanes 26.
- a washing device including two side walls extending longitudinally and vertically and spaced apart, a lateral wall extending between said side walls to provide a bottom wall and two opposite end walls and connecting with said side walls in unitary relation to provide a container, and the inner surface of said bottom wall and the inner surfaces of said end walls substantially faired to provide substantially curved inner surfaces at the regions of juncture, and said walls terminating upwardly to substantially provide an upper opening for overflow liquid and said container adapted for vertical circulative flow, and said end wall at the normal upflow end of said container and adjacent segments of said side walls extending to a higher elevation locally than said upper opening for overflow liquid, and a transverse substantially vertical walllike portion extending between said higher side wall segments and spaced from said end wall normally to provide a vertical enclosure to contain a liquid column in normal operation at a higher level than said upper opening for overflow liquid.

Another object is to provide for augmentation of the inlet jet by the contained circulating liquid to increase the eflective jet mass at reduced net velocty thereby preserving momentum and reducing kinetic energy losses and improving eficiency.
A number of other Objects and advantages will become apparent as the description proceeds.
One form of the present invention is illustrated in the accompanying drawings wherein similar numerals refer to similar parts throughout the views.
FIGURE 1 is a side View of the fruit and Vegetable washing device properly positioned beneath an open water faucet. The arrows indicate the flow path of the circulative liquid flow.
FIGURE 2 is a plan view of FIGURE 1 showing the comparativelynarrow width, W of the washing device,
and details of the cover or closure member.
FIGURE 3 is a section along line 3--3 of FIGURE 1 showing, to a larger scale, the typical cross-section of a food unit defiector and liquid guide vane.
The prior art has provided a narrow two dimensional washing device of the present type, as for example that described in copending application of Serial No. 246,- 715 filed Dec. 24, 1962, now Patent No. 3,208,732. That configuration includes a cover specific means for liquid exhaust flow. The cover element thereof is effective and functions to provide important advantages as described therein. A principal purpose of the present invention is to contribute materially to the preservation of and even to the generation of contained flow which is two dimensional, and hence of ncreased efiicicncy. This allows operation of the device at lower available water pressures, or for the cleaning of larger loads of food units at a given water pressure.
Referring to the several figures, washing device l is comprised of side walls 2 and 3 extending longitudinally and vertically and spaced apart in relative proximity. A lateral wall 4 extends between side walls 2 and 3 to provide a bottom wall 5 and two opposite end walls 6 and 7. The bottom wall 5 and end wall 6 are faired together by radius R to provide a curved inner surface, as shown.
The liquid inlet unit 8 is comprised of a vertically extending duct portion 9, an upper inlet port 10 open upwardly to the atmosphere, and lower exit port 11 which is submerged below normal liquid Operating level. Exit port 11 is of elongated cross-section, wherein the major axis is perpendicular to the plane of end wall 6. Inlet port 10 is circular and oversize, and duct portion 9 tapers downwardly to elongated exit port 11. Inlet unit 8 is fastened to end wall 6 by clip 12. The washing device, in service, is postioned under open faucet 13, as shown in FIGURE 1 so that free water jet 14 is in line with inlet port 10. This establshes vetical circulative flow within the device as indicated by the arrows in FIG- URE 1. V
The increase in performance ability of washing device 1 is due to the character of lid or closure portion 15-. Closure portion 15 is in three cooperating portions, which may be used separately or in combination. Center closure portion 16 is bonded along line 17 to liquid deflector portion 18, and along line 19 to food unit deflector portion 20. Liquid deflector portion 18, center closure portion 16, and food unit deflector portion 20` function simultaneously to contribute to the preservation of the two dimensional liquid flow within the container. Their combined results are more than the sum of their separate results, since lateral flow deviations are continuously suppressed by each of the three portions. The omission of any portion would command a greater restoring effort from the remaining portions which would therefore be less eflicient due to stronger liquid cross flows and eddies.
Liquid exhaust occurs through the plurality of narrow, elongated slots 21 in center closure portion 16'. The flow is up through slots 21 in a plurality of thin parallel streams. Exhaust liquid forms in a thin sheet on the upper surface of center closure portion 16 and flows outwardly to the two edges, and from there runs overboard to the floor of the snk. Thus, exhaust flow from the container is two dimensional and does not induce cross currents within the container. This aids in preserving two dimensional flow within the container. These details are essentially in accordance with those of referenced Patent No. 3,208,732.
Food unit deflector portion 20` is comprised of a plurality of deflector vanes 26 cantilevered from support 27. Tabs 28 and 29 extend downwardly from support 27 to externally grip side walls 2. and 3 by a friction fit. Optionally, deflector portion 20 may not be bonded to center closure portion 16 along line 19, in which case tabs 28 and 29 may be bonded to walls 2 and 3 to provide fixed support for deflector vanes 26.
