Description

ACCESSORY FOR DISHWASHER
[0001]
BACKGROUND OF THE INVENTION
100021 A dishwasher removes unwanted foreign substances from reusable crockery and utensils using washing liquid injected through an injection nozzle. The nozzle may be located in various locations inside the dishwasher, e.g., typically directly beneath the dishes, or, in the case of U.S. Patent 3,167,183, may be located beside the dishes.
The removed substances then drop to the bottom of a tub beneath the dishes.
[0003] Typically, a dishwasher contains at least one crockery basket or rack, usually two, each with a number of upstanding tines to hold the crockery in an upright position to allow for maximum cleaning. Occasionally, as shown in U.S. Patent 7,793,790 B2, dishwashers will contain a bottle rack for separately placing dishware products having a hollow shape, such as milk bottles and feeding bottles, in a vertical position to maximize cleaning. As shown in U.S. Patent 4,927,033, an article holder for the dish rack of a dishwasher is provided for securely holding cup shaped articles in an upright position on the sides of the basket. In U.S. Patent 2,655,267 a detachable device to prevent damage to glasses and cups from heavier metal instruments by more forcefully supporting the objects is disclosed. U.S. Patent 4,593,822 discloses an arrangement to prevent damage to dishware due to the deterioration of coatings of a wire rack due to continued exposure to high levels of heat by introducing a removable and replaceable sleeve. As shown in U.S. Patent

2,841,288, plates are occasionally held in place by tilted racks on both sides and with raised lower supports extending from one tilted rack to the other, and also holding the dish. In addition to dishes, specific types of reusable bags can also be washed in dishwashers, using the special dishwasher attachment shown in U.S. Patent 5,405,018.

DETAILED DESCRIPTION
[0014] The present technology is described in relation to several examples that may share one or more common features. It should be noted that an aspect of one example can be combined with an aspect of another example, and that any aspect of any example may form the basis for subject matter applicant may wish to pursue.
[0015] Figure 1 is a schematic view of a dishwasher 5 for washing and/or drying crockery items, such as dishes, frying pans, cookie sheets, cutting boards, bowls, pots, etc.
Dishwasher 5 includes a manually openable door 10 and a compartment 15. Door 10 is openable to allow access to the compartment 15. Door 10 will form a generally water/air tight seal relative to the compartment 15 when closed. The compartment 15 includes at least one crockery basket 20, 25.
[0016] Figure 2 shows further details of a portion of the sample crockery basket 25, within which are several rows of generally parallel base rails 27 and upright tines 30, generally used to support the items of crockery to maximize cleaning efficiency.
However, sometimes the existing tines 30 are not enough to fully and/or optimally stabilize larger and/or irregular items, in a space conserving manner, in which case such items may not be fully washed/rinsed, or they may impact the loading/cleaning efficiency of surrounding items. There are several different designs for the dishwasher accessories, and each one may be specifically designed to support a different type of crockery item, or they may be adjustable.
[0017] Figures 2 through 8 show a first example of a dishwasher accessory 45 of the present technology. The dishwasher accessory 45 attaches or is otherwise provided to the crockery basket 20, in an easily removable manner. Dishwasher accessory 45 can be provided to the base rail 27, existing tines 30, or even sides of the basket 25.
[0018] As shown in Figure 2, accessory 45 has a main body 46, a proximal end 50 that is attached to the basket and a distal end 55 that extends away from the distal end 50. The accessory 45 may have a generally U-shape, including a pair of legs 60 and a connecting portion 56 (Figure 4) although other shapes are contemplated. The U-shape is able to better fit the contour of dishes and other crockery and avoids the potential for sharp points (e.g., from existing Attorney Docket No.: 2011P01980US

tines) that may cause damage to the crockery and/or premature wear on the accessory itself, which may be a malleable wire coated with a soft layer, e.g., plastic, etc.
[0019] The spacing between the legs may be about 4-15 cm, e.g., 5-8 cm, or 8-12 cm (or roughly about 95mm) to ensure adequate contact with the crockery, and/or to best ensure stability of the crockery in an upright or optimal cleaning position that can robustly withstand the various cleaning/rinsing cycles which occur in a dishwasher. If the distance between the legs is less than 4cm, then the stability of the crockery may be compromised, and if the distance is greater than about 15 cm, then the accessory will be wider than a large percentage of the crockery that is intended to be supported by the accessory.
[0020] The U-shape may also include smooth, radiused transitions 57 (Figure 4) between the legs 60 of the U-shape and the connecting portion 56 or distal end 55 of the U-shape, to enhance stable support. The distal end 55 and/or the radiused transitions 57 are intended to support the crockery.
[0021] Each leg 60 of the U shape may include an attaching member for attaching to the base rails 27 of the basket 25. In Figure 2, each end of the legs 60 includes an attaching member in the form of a claw 65, one attached or otherwise provided to each leg 60 of the accessory.
Each claw 65 includes a cross member 70 and at least one hook member 75, with two such hook members for each claw 65 being shown in the example of Figure 2. The hook members 75 are spaced to provide sufficient stability.
[0022] Figures 2 and 3 show the accessory 45 in the attached or installation position relative to the basket 25. As shown in Figure 3, the angle of the main body 46 is selected to match the angle of the existing tines 30 (part of the accessory 45 is hidden behind the tine 30), which helps to ensure that the accessory blends 45 with the basket 25, to help maintain maximum loading capacity and cleaning efficiency. The main body 46, e.g., the distal and/or proximal ends 50, 55 of the accessory 45 can be adjustable relative to the cross member 70, e.g., by using deformable materials such as malleable wires, to allow the angle of tines to be matched.

Attorney Docket No.: 2011P01980US

[0023] Figure 3 shows the distal end 55 of the accessory 45 to extend an exposed height h that is greater than the height of the tines 30, e.g., in the range of about

5-10 cm. The accessory has an overall height of approximately 10-20 cm.
[0024] While Figures 2 and 3 show the accessory in the attached or installation position, Figure 4 shows the accessory in the pre-attached, pre-installation position.
As shown in Figure 4, the legs 60 are pulled outwards from both sides in the directions indicated by the arrows until the distance 76 between the claws 65, and more particularly the tips of the hooks 75, is more than the distance 77 (Figure 2) between the base rails 27. Once the legs 60 are stretched to achieve this distance, they are released at which point the resiliency of the legs causes the hooks 75 to "snap" in and firmly engage the respective rails 27. It can be appreciated that the legs 60 in Figure 4 converge towards one another as seen in the direction of the proximal end 50 of the accessory 45, but the legs 60 are generally parallel once the accessory 45 takes up the attached position (Figure 2).
[0025] Figure 4 shows that the hook 75 is formed at an angle a relative to the cross member 70 of the claw 65. Figure 8 shows the accessory 45 from the front, making more apparent the angle a between the cross 75 and the hook 80 that makes supporting larger crockery easier. The angle a is in the range of 5-45 degrees, or about 10-30 degrees.
[0026] Figure 5 shows the accessory in side view, including the angle p that is between the proximal end 50 and the cross member 70. Angle p is in the range of about 45 to less than 90 degrees or about 60-75 degrees. The angles a and 13 may be adjustable, e.g., by making the accessory of spring wire that can be deformed.
[0027] Adjustability may be provided in the form of an adjustment mechanism, e.g., to allow selection of two or more predetermined positions, e.g., like corrugations in a drinking straw may allow the tip of the straw to assume a number of positions. As seen in Figures 6 and 7, the angle f3 may result in the distal end 55 of the accessory being positioned slightly outward of an extent 73 between the hooks 75. Although the distal end 55 is shown to project a small distance 71 (e.g., of a few millimeters, e.g., 1-10mm) outside one of the hooks 75, the distal end 55 may be positioned within the extent 73 and between the claws as seen in Figures 6 and 7.

Attorney Docket No.: 2011P01980US

Such configuration helps to provide stability (given the distance between the hooks) and at the same time allow the angle r3 to match the angle of the tines in the basket.
[0028] Figures 9 through 13 show a second example of a dishwasher accessory 200 according to the present technology. Accessory 200 is similar to accessory 45 and thus parts that operate in the same manner will not be repeated for the sake of conciseness, where like reference numbers indicate like parts. Accessory 200 differs from accessory 45 in a variant on the way that it can be attached to the crockery basket's base rails 27. As shown in Figure 9, the claws 265 are rotated 90 compared to the claws 65 shown in Figures 2-8. The claws 265 may be fixedly attached in this manner, or they can be adjustable via an adjustment mechanism, e.g., the proximal end 250 may be swivelable or rotatable relative to the cross member 270. When in this position, the claws 265 can be squeezed in the direction indicated by the arrows against the natural resiliency of opposed legs 260 of the accessory, which again has a generally U-shape.
This is in contrast to the pulling the legs outwards in relation to accessory 45.
[0029] Figure 10 features the accessory 200 in a relaxed, pre-installation position (solid lines) as well as in the installation position (broken lines). Again, the legs 260 are generally parallel to one another in the installation position, and generally not parallel (diverging away from one another in the direction of the proximal ends 250) in the pre-installation position. As compared to accessory 45, a distance 266 between the claws may be less than the distance 76 between the claws as shown in Figure 4, which distance may be more useful if the base rails 27 of the basket 25 are closer to one another.
10030] As shown in Figure 14, an accessory 290 can also be manufactured of a material (e.g., spring wire) that that allows the claws 65, 265 to be positioned in either the inwardly facing orientation (Figures 2-8) or alternatively the outwardly facing orientation (Figures 9-13). Figure 14 shows the inwardly facing orientation in the broken lines, which can be converted into the solid line orientation by bending one leg 60, 260 over the distal end as indicated by the arrow until the claws 65, 265 face away from one another.
[0031] Figures 15 and 16 show another example of an accessory 300 according to the present technology. Accessory 300 is similar to accessory 45, but has an exposed height H, i.e., Attorney Docket No.: 20 1 1P0 19 80US

the amount it rises above the tines 30, that is greater than the exposed height h shown in Figure 3 in relation to accessory 45. The greater height H allows for better and/or more complete support of even taller pieces of crockery, e.g., cookie sheets. The exposed height H
is approximately 10-15 cm.
[0032] Figure 16 also shows that the claw 365 to have a slightly different shape.
Specifically, the claw 365 includes a cross member 370 and a hook 375, as above, but the hook 375 is generally radiused rather than being angled relative to the cross member 370.
[0033] Figures 17-22 show another variant of an accessory 400 according to the present technology. Accessory 400 includes a proximal end 450 and a distal end 455, but the proximal end 450 attaches onto the crockery basket in a different manner as compared to the examples discussed above. For example, the accessory 400 is U-shaped and includes first and second legs 460, the proximal end of which is connected to the tines 30 (Figure 22). In the specific example shown each end 450 has a hollow tip portion 451 dimensioned to receive the end 30.1 of an existing tine 30 of the crockery basket 25. Specifically, the inner diameter d of the hollow tip portion is about equal to, or slightly greater or less than, the diameter D
(or cross sectional dimension) of the end 30.1 of tine 30. The hollow tip portions 451 may take the form of a blind bore to limit the insertion depth (e.g., 1-2 cm) of the tines 30 into the hollow tip portions 451 of the accessory 400.
[0034] As shown in Figure 18, accessory 500 has a general "U" shape, with the distal and proximal ends being in the same general plane, as also shown in Figures 19-21.
The distal end provides a smooth surface such that crockery, e.g., a plate or pan 499 (Figure 22) with a shallow concavity, can be supported in a position that is more ideal for dishwashing machines and without scratching and with improved stability.
[0035] Figures 23-28 show an accessory 500 according to another aspect of the present technology. Accessory 500 shares many similarities with accessory 400. One main difference is that the accessory 500 has a more pronounced three dimensional shape to better support crockery with a deeper bowl area, as shown in Figure 28. The accessory may have a pre-defined shape, or it may start off in a generally planar state as in the accessory 400 and be bent or shaped to match CA 02792623,2012-10-19 Attorney Docket No.: 2011P01980US
the general dimensions or depth of the crockery to be supported, e.g., by plastic deformation and/or by elastic deformation due to the weight of the crockery.
10036] Accessory 500 has a generally U-shape with a pair of legs 560 or proximal portions 550 and a connecting portion 556 or distal portion 555 that connects the legs 560 to one another. Legs 560 have hollow tips 551 as described above, and begin to curve at a distance 553 that is about two thirds of the total height 554 of the accessory 500. The connecting portion 556 extends at an angle 6 that is about 50-80 degrees relative to the legs 560.
This shape helps to support bowls or other deeply concave crockery, e.g., pots.
[00371 While the accessory shown in Figures 23-28 includes hollow ends that receive tines of the basket, in an alternative, the accessory 500 may be attached to the basket using an attachment mechanism like those shown and described in relation to Figure 8 or Figure 9, e.g., claw like attachment mechanism.
[0038] While the present technology has been described in connection with what are presently considered to be the most practical and preferred examples, it is to be understood that the technology is not to be limited to the disclosed examples, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the disclosure.
