Description

Dishwasher holder.

The present invention relates to a dishwasher holder.

In general, the present invention is applied to the field of dishwashers comprising a washing tank in which one or several dishes baskets can be arranged.

The cleaning of the dishes placed in these crockery baskets is done by spraying, thanks to windlasses arranged below and / or above the crockery basket that allow directional water jets to be sent over the crockery.

It is therefore important that the dishes are properly placed in these baskets so that the dishes to be cleaned, usually glasses, bowls, plates, cutlery, cooking vessels, can be cleaned by means of water jets while being maintained stable in crockery baskets.

The arrangement of the crockery elements must also be compatible with the process of drying by circulation of hot air in the washing tank.

In a traditional dishwasher, dishware baskets are equipped with tableware holders dedicated to different types of dishes.

Generally, the lower basket is intended to accommodate a relatively dirty tableware, of the dish, dish, casserole, pan type, while the upper basket is intended to accommodate a less dirty tableware, of the bowl, glass, cup type.

In particular, the plates are held in place substantially vertically thanks to a series of rods of rilsanized wires.

However, a structure of rods of this type, although it can be folded to the bottom of the basket for dishes for the placement of large-scale fountains, does not allow the stable maintenance of vessels or bowls.

There are also flat support structures, generally inclined, and that act together with vertical walls to allow the placement of vessels or bowls.

These flat support structures do not allow the vertical placement of plates or saucepans.

Also known from DE-U-20 2005 001 096 is a plate support area formed by a structure comprising grooves. However, this support area is limited to the vertical placement of plates.

Also known from DE-U-20 201 02 169 is a plate support area formed by fins that extend respectively in vertical planes.

The present invention aims to solve the aforementioned drawbacks and propose a dishwasher holder that allows a universal load of different pieces of dishes in the same support area.

To this end, the present invention relates to a dishwasher support as defined in claim 1.

Such a structure optionally allows plates to be held in position thanks to the presence of grooves and other pieces of crockery, of the glass, bowl type, placed in contact with the curved and curved surface of the structure.

A support area of this type that creates a concave shape that protrudes from the tableware support plane, allows a universal load of the tableware support.

This tableware holder offers greater modularity when loading a dishwasher.

The specific curved profile of the arches is well adapted to the maintenance of the dishes.

Preferably, the surface forms, at the level of the union of the structure with the plane of the tableware support, an angle between 25 ° and 45 °.

This angle formed by the curved surface that protrudes from the plane of the tableware holder is particularly well adapted to the placement on this curved surface of glasses, cups, bowls, by offering a suitable inclination both for washing these elements and for drying, avoiding the stagnation of water at the bottom of bowls, cups or glasses.

Advantageously, the radius of curvature of the surface is between 50 mm and 200 mm.

The grooved structure therefore has a curvature particularly well adapted to the maintenance of dishes.

The present invention also relates to a dishwasher basket that integrates a tableware holder according to the invention.

Preferably, at least one plate support area is adjacent to a substantially vertical wall of the dish basket.

This wall therefore allows the creation of a stop to keep in an inclined position elements of the glass, bowl, cup type, placed on the curved and domed surface of the structure.

The present invention also relates to a dishwasher comprising a washing tank and at least one basket for dishes according to the invention.

This dishwasher has advantages and characteristics analogous to those of the tableware holder and the dishwasher basket described above.

According to a preferred embodiment, the dishwasher comprises two dishware baskets that respectively integrate two identical tableware holders.

Thanks to the use of a tableware support with loading areas, which allow the placement of dishes, fountains, glasses, bowls, it is possible to equip the dishwasher with identical tableware holders in each tableware basket.

Therefore, in addition to the possibility of a traditional load, which includes dishes, sources and the like in a lower basket and glasses, bowls and the like in an upper basket, it is also possible to carry out a similar load in the two dishes baskets, and by example make a load only of glasses.

Other particularities and advantages are further derived from the following description.

Referring to the figures, a dishwasher basket according to different embodiments of the invention is described.

The invention applies in particular to a dishwasher 1 as illustrated in Figure 8 which comprises a washing tank 10 containing two dishes baskets 20, 30.

For reasons of clarity in the illustration, the right part of the baskets 20, 30 has been removed in Figure 8.

Obviously, the number of dishware baskets is not limiting, the dishwasher in particular being able to comprise a single dishware basket in a washing tank.

Generally, the upper tableware basket 20 is mounted on guide rails fixed inside the walls of the washing tank so that it can be removed from this tank for loading and unloading the dishes.

Likewise, the lower tableware basket 30 rests on rails arranged at the bottom of the washing tank and on the counter door 2 of the dishwasher 1 so that it can be removed for loading and unloading the dishes.

A windlass 21, 31 can be placed under each crockery basket 20, 30 which allows directional water jets to be sent to clean the dishes arranged in the crockery baskets.

In this embodiment, a dishwasher 1 is illustrated, comprising a separation wall 3 that separates the washing tank 10 into two parts, a basket for dishes 20, 30 being arranged in each of the parts of the washing tank 10.

In this case, the separation wall 3 is disposed substantially at mid-height of the washing tank 10, thus creating two washing compartments of substantially identical dimension.

A dishwasher of this type allows, in particular, a separate and independent operation of the upper part and the lower part of the washing tank, simultaneously or not.

In this embodiment, and in a non-limiting manner, each dish basket is equipped at the front with a front face 4, 5 in order to isolate each half of the washing tank during its different operation and protect the counter door 2 against to splashes of water or dirt.

Obviously, the invention is applied in the same way to a single wash tank containing two dishes baskets.

A tableware holder adapted to be equipped is illustrated in Figure 1, and for example the upper tableware basket 20 as illustrated in Figure 3.

The basket for dishes can be made in a metallic structure of rilsanized wires, and presented in the form of a lattice structure.

The realization of such a basket for dishes of this type will not be detailed here, from transverse wires 22 and longitudinal wires 23 that extend in a plane and thus constitute a perforated bottom of the tableware basket 20.

In addition, wires 25 partially or totally surround the contour of the basket for dishes 20.

These wires 25 are welded at the folded ends of the transverse wires 22 and the longitudinal wires 23.

The contour 25 of the basket thus forms edges or side walls 26 or transverse 27.

The front face 4 is made for example by a vertical plastic wall, placed at the level of a front transverse wall 27 of the dishware basket 20.

The tableware basket 20 is adapted to integrate a particular tableware holder such as that illustrated in Figures 1 and 2 according to a first embodiment.

This tableware holder 40 comprises at least one plate support area.

In the embodiment illustrated in Figure 1, this tableware holder 40 comprises two plate support areas 410, 420. First, a first plate support area 410 will be described, the second support area being

of dishes 420 similar, except for certain dimensions as explained below. The plate support area 410 is formed by a structure comprising grooves 411. These slots 411 allow in particular the introduction of plates in the plate support area 410. The structure cover of this plate support area 410 constitutes a curved and curved surface

which extends above the plane P of the tableware holder, in this case substantially adjacent to the plane

horizontal bottom of the basket for dishes 20. The structure of the plate support area 410 thus constitutes a concavity whose rounded part is it has in front of the plane P of the tableware holder 40.

In this embodiment, the domed structure is constituted by a series of separate arches 412

from each other. The space between two adjacent arches 412 makes it possible to create a slot 411 suitable to accommodate one more plate or less inclined with respect to the plane P of the tableware holder 40.

The surface of these arches has a curvature that allows straddling these arches of

pieces of crockery of the type glass, bowl, saucepan, cup (see in particular figure 3). As illustrated well in Figure 2, the radius of curvature R1 of the surface is between 50 mm and 200 mm

On the other hand, in order to offer a suitable inclination for bowls or cups placed on it curved surface, this forms an angle between 25º and 45º between this structure and the plane P of the tableware holder

Preferably, this angle is between 30 ° and 35 °, and for example equal to 32 °. Thanks to this inclination, as illustrated in Figure 3, when a bowl straddles the arches 412 of the curved structure, the inclination of this bowl is of the order of 35 °, such that it is possible

obtain a good drying performance of this bowl, and in particular avoid the stagnation of water in the bowl bottom. Also, the curvature of the structure constituted by the arches 412 allows to place vessels in this structure of

so that its inclination is of the order of 21º, also allowing good yields of

dried Returning to Figure 1, the tableware holder 20 comprises, as indicated above, two areas of plate holder 410, 420.

These plate support areas are arranged in parallel to the direction corresponding to the depth of

the basket 20 when the tableware holder 40 is integrated in the tableware basket 20. They are also arranged side by side across this tableware basket 20 so that they are created two support areas for parallel plates.

In this exemplary embodiment, the first plate support area 410 comprises thirteen arches 412. The second plate support area 420 comprises eleven arches 422. Obviously, the number of arches is not at all limiting, and allows you to create, between each arc, a space or

slot 411, 421 capable of accommodating a plate.

The first support area 410 is adapted in this case to support in each slot 411 flat plates of small or large dimensions, and for example of a diameter between 20 and 26 cm. The radius of curvature R1 of the curved and domed surface of the first plate support area 411 is therefore between 120 mm and 150 mm, and for example is substantially equal to 140 mm.

The second plate support zone 420 is intended to support deep plates.

The curved and domed surface of the structure of the second plate support zone 420 has a radius of curvature R2 comprised between 70 mm and 90 mm, and for example is equal to 80 mm.

On the other hand, to allow the maintenance of elements such as vessels, or bowls, on the curved surfaces of the plate support areas 410, 420, the plate support areas 410, 420 are adjacent to a substantially vertical wall of the crockery basket 20, and for example in the embodiment illustrated in Figure 3, to the side walls 26 described above.

This tableware holder 40 is fixed to the structure of rilsanized wires of the tableware basket 20 for example by means of forms 41 dedicated to engaging the holder 40 in the rilsanized wires of the basket

twenty.

These forms of engagement 41 are made at the edges 42, 43 of the tableware holder 40.

On the other hand, the tableware support 40 may comprise stops 413, 423 at the end of the arches 412, 422, at the level of its base part that joins these arches to the side edges 43 of the tableware support 40.

As illustrated well in Figure 2, these stops 413, 423 allow to maintain in an inclined position elements of the bowl, vessel type, placed on the curved surface of the plate support area 410, 420.

These stops 413, 423 prevent the sliding of the vessels and bowls over the arches 412, 422.

In addition, the arches 412, 422 may comprise stops 415, 425 made in the arches 412, 422, by rounded prominences at the top of the arcs 412, 422.

These stops 415, 425 prevent any sliding of the vessels or bowls placed on the curved and domed surface constituted by the rounded upper portions of the arches 412, 422.

Thanks to the presence of these plate support areas 410, 420, the loading of the basket is universal since it allows at the same time the loading of plates or the loading of glasses, bowls, or cups in the same support structures for dishes .

As a complement to these plate support areas 410, 420, the tableware holder 40 may further comprise one or more inclined flat areas 50 that extend across the tableware holder 40, and adapted to support vessels, or bowls, or even to accommodate accommodation for cutlery.

In this exemplary embodiment, the tableware basket 20 comprises two flat areas inclined 50 towards the front of the tableware holder, that is to the front face 4 of the tableware basket 20.

These inclined flat areas 50 are made by a cross structure of curved or straight bars 51 that define a perforated surface.

On the other hand, the structure of the dishware basket 20 can also integrate side grilles 60 mounted on the wires 25 of the contour of the dishware basket 20, at the level of the side edges 26.

These grilles 60 are generally made of a plastic structure that engages the rilsanized wires 25 of the contour 25 of the dishware basket 20.

In this way, the vessels with foot resting on the arches 412, 422 have their foot held by notches 61, in the form of battlements, arranged in the side grilles 60.

This tableware basket 20 also allows one or more cutlery trays (not shown), of traditional configuration, to be placed in different areas of the basket 20, on the tableware holder 40.

These cutlery baskets can rest on the arches 412, 422 and the side edges 26 of the crockery basket 20, or even on the inclined surfaces 50 on the front of the crockery basket 20.

A basket for dishes of this type equipped with a universal tableware holder can be used interchangeably at the top or bottom of a dishwasher washing tank.

In this embodiment, the dishwasher as illustrated in Figure 8 may comprise two dishware baskets 20, 30 having an identical tableware holder 40.

Thanks to the modularity of the tableware load on the tableware holders described above, all tableware pieces can be easily placed anywhere in the tableware basket.

In particular, the curved structure of the plate support areas does not create protruding elements in the plane of the crockery basket, which may disturb the provision of bulky utensils such as salad bowls, casseroles.

These bulky utensils can be placed, as described above for the glasses or bowls, directly on the curved and domed structure of the tableware holder, astride the arches 412,

422

By using identical dishware baskets for both the top and bottom of a dishwasher, a glass, cup and saucer load can be made in a top basket 20 and a source, pan and dish type load in the basket lower crockery 30.

In a second configuration, an identical load can be made in the two dishes baskets 20, 30.

By way of examples, it is possible to place approximately forty glasses without a foot in a tableware holder as described above.

On the other hand, when the dishwasher has its washing tank 10 separated in two different cleaning zones, each dish basket 20, 30 can be loaded differently or identically and adapted washing programs are implemented in each half of the tank.

Each plate support structure 410, 420 will now be described in reference to Figures 4 to 6.

As illustrated well in Figure 6, each arch 412, 422 extends over a complex surface substantially inclined with respect to the plane P of the tableware holder 40 and to the bottom 24 of the tableware basket 20.

Each arc thus forms an arc of circle of radius of curvature adapted and extending substantially up to a height between 40 and 50 mm above the bottom 24 of the dishware basket 20.

Each arch 412, 422 extends between a side edge 43 and a central bar 44 of the tableware holder 40.

The height of the arches 412, 422 is determined in such a way that the bottom of the plates of traditional size comes into contact with an arch 412, 422.

More generally, the shape of each arc 412, 422 is determined from a truncated revolution surface corresponding to a virtual plate profile that is globally inclined. Each arch 412, 422 therefore has a curved profile, above the plane P of the tableware holder, as can be seen in the figure

3.

As can be seen in the figures, each arc 412, 422 has a curved profile at the same time in a vertical projected plane (see figure 4) and in a horizontal projected plane (see figure 5).

Each arch 412, 422 is separated with a regular pitch between 15 and 30 mm, and preferably between 20 and 25 mm.

By way of non-limiting examples, the first series of arcs of the plate support area 410 has a regular passage between the arches of the order of 23 mm adapted for the placement of plain or dessert plates as illustrated in Figure 5 .

The second plate support area 420 also comprises a series of arches 422 whose separation is of the order of 24.5 mm, adapted for the placement of deep plates, whose thickness between the bottom and the edges of the plate is more important than for flat dishes.

As illustrated well in Figure 6, the arches 412, 422 are therefore respectively extended by complex surfaces parallel to each other and inclined with respect to plane 24 of the crockery basket.

On the other hand, a rack 430 constituted by teeth 431 having a predetermined inclination is arranged in a direction parallel to the longitudinal direction of the series of arches 412, 422.

This rack 430 therefore extends along the direction parallel to the depth of the basket 20, parallel to the side edges 26.

The teeth 431 are arranged protruding from the bottom plane 24 of the dishware basket 20.

As also illustrated in Figure 5, the teeth 431 are separated with a regular pitch, equal to the step separating the arches 412, 422.

This zipper constituted by teeth 431 allows to keep the plates placed in the grooves 411, 421 at the level of their lower edge that comes into contact with the bottom 24 of the basket 20.

In order to further improve the maintenance in position of the dishes above the bottom 24 of the dishware basket 20, the support structure comprises two identical zippers 430 arranged symmetrically with respect to a plane of symmetry of the series of arches, that is to a vertical plane that extends along the depth of the basket 20 (see in particular Figure 2).

In this way two support points are created in the bottom 24 of the dishware basket 20 for each plate, preventing the latter from rotating between the arches.

The teeth 431 of the zippers are made directly in the structure of the dishware basket 20, for example by means of a rilsanized metal wire welded to a longitudinal wire 23 of the dishware basket 20.

The shape of the teeth 431 of the zippers is determined in such a way that the position of the plates above the plane 24 of the basket 20 allows to guarantee at the same time the passage of the water jets in order to obtain satisfactory washing performances , and get a good drying of the dishes.

The shape of the teeth is determined so that the plates are tilted backwards at an angle between 0 and 5º with the vertical.

Obviously, the zippers could also be made of plastic material and mounted, for example by hooking, on the structure of rilsanized wires that constitutes the basket for crockery 20.

The zippers could also be replaced by series of simple wedges.

As well illustrated in Figures 4 and 5, each arc comprises at least one projecting element 414, 424.

These protruding elements 414, 424 are intended to form a substantially point contact point of the plates on a surface of each arc 412, 422.

In this embodiment, each projecting element 414, 424 is constituted by a line of small dimension that extends over the surface of each arc 412, 422, intended to come into contact with the bottom of a plate.

Each protruding element 414, 424 can therefore be made by oval moldings that extend along the height of the profile of each arch 412, 422.

These protruding elements make it possible to guarantee the support of the plates on substantially point contact points.

In the second plate support area 420, intended to mainly support deep plates, two protruding elements 424 are arranged on a surface of each arc 422, symmetrically with respect to an axis of symmetry of this arc 422.

As illustrated well in Figure 5, the distance between these two elements 424 is adapted to correspond to the classic diameter of a bottom of a deep plate.

For the first plate support area 410, intended to support both large-format flat plates and flat dessert plates, each arch 412 preferably comprises four protruding elements 414 arranged symmetrically with respect to an axis of symmetry of the arc 412 .

Each arc 412 thus comprises a first pair of projecting elements 414 arranged symmetrically with respect to the axis of symmetry of the arc and whose distance substantially corresponds to the classic diameter of the bottom of a dessert plate.

A second pair of protruding elements 414 are arranged symmetrically with respect to the axis of symmetry of the arc 412 and separated by a greater distance, which substantially corresponds to the diameter of the bottom of a traditional flat plate.

Thanks to these substantially point contact points on the bottom of the plates, these plates are only held in position at the level of the teeth 431 of the zippers 430 and of the protruding elements 414, 424.

Consequently, the risks of water retention at the level of the contact points are minimized, as well as the risks of food jamming between the plates and the contact points of the support structure.

By way of non-limiting example, the protruding elements 414, 424 can be constituted by oval moldings having a thickness on the surface of each arch 412, 422 between 1 mm and 1.5 mm.

Preferably, the tableware holder assembly 40 is made of plastic material, and preferably of a rigid plastic material that has good elasticity and high resistance to deformation.

This plastic material must be resistant to the temperature and chemical aggressions of the detergent bath used in the dishwasher washing tank.

The use of a robust plastic material of this type allows the tableware support structure to be made at a lower cost while ensuring the maintenance of the tableware pieces in a stable position during a dishwasher operation cycle, and this during all the life span of that dishwasher.

It is important in particular that the arches 412, 422 do not undergo deformation caused by the weight of the dishes and the heat transmitted by the wash bath.

By way of non-limiting example, the tableware support structure 40 is made of polypropylene loaded with glass fibers.

This choice of material allows to obtain a good resistance to chemical aggressions, and a good mechanical resistance and particularly to deformation. On the other hand, this material is low cost.

Thanks to the use of a plastic material to make the tableware support 40, this plastic material can also be overmolded with an elastomer so that the shocks for fragile tableware pieces are cushioned.

The use of an elastomer of this type also makes it possible to improve the adhesion of the dishes against the arches, and in particular of the vessels or bowls as illustrated in Figures 2 and 3.

This improves the stability of the dishes arranged on the curved and domed structure above the plane 24 of the dishware basket.

In order to limit the manufacturing cost of this tableware support structure, the overmolding of an elastomer could also be limited to certain areas, and for example to parts of the arches 412, 422 intended to come into contact with the tableware and which They can be sensitive to shocks while loading dishes.

In the tableware support structure 40 described above, it is also important to improve the passage of the water jets in the direction of the dishes to be cleaned, and in any circumstance, not to disturb the projection of these water jets.

In this regard, the tableware support structure 40 described above comprises different curved or rectilinear elements, generally of plastic material.

These elements are in particular the arches 412, 422, the edges 42, 43 and the curved or straight bars 51.

These elements have at least one wall that extends substantially in an oblique plane with respect to the horizontal plane of the bottom 24 of the dishware basket 20.

As illustrated well in Figure 6, for an arch 412, the cross section of this arch is shaped like an airplane wing.

More precisely, the cross section of the profiled curved element constituting the arch 412 comprises an acute angle edge 415 directed substantially downward, in the direction of the horizontal plane of the bottom 24 of the dishware basket 20.

Therefore, for each arch 412, while the curved profile of each arch is substantially inclined with respect to the plane of the bottom 24 of the dishware basket 20, the cross section of each arch comprises an acute angle edge directed towards the bottom of the crockery basket 20.

More precisely, each profiled element comprises a substantially flat wall 418 and a contoured wall 417, the intersection of these walls constituting the sharp angle edge 415 as described above.

Opposite this sharp angle edge 415, a circle-shaped part 416 allows the flat wall 418 to be joined with the contoured wall 417 of the profiled element.

This specific embodiment of the cross-section of the curved profiled element that forms the arc 412 allows the water jets to be directed preferably towards the dishes as is well illustrated in Figure 7 by means of the arrows that schematize the direction of the water jets.

The substantially flat wall 418 makes it easy to demould the plastic arch 412 during its manufacture.

The contoured wall 417 makes it possible to improve the stiffness of this arc by increasing the width of the cross section in the direction perpendicular to the inclined plane containing the arc 412.

The bevel shape of the edge 415 therefore allows the water jets to optimally reach the dishes to be cleaned.

While a different form would resend the water jets to the washing tank, this bevel shape of the cross section allows the water jets to be reflected on the walls 417, 418 of the cross section of the arc profile 412 and therefore direct these jets of water towards the dishes, and in particular towards the plates arranged in the grooves 411 on each side of this arch 412.

In order to further improve the steps of the water jets produced by the windlass 21 disposed under the tableware basket 20, the structure of the tableware holder 40 comprises at least one side edge portion 43 forming a deflector, adapted for direct the water jets into the tableware holder 40 (see arrow in figure 4). In this regard, the side edges 43 comprise recessed portions 43 ', which form baffles to guide the water jets towards the center of the tableware holder 40. In addition, the tableware holder 40 comprises, as illustrated well in Figure 2 , side edges 43 whose height extends under the lower plane P of the tableware holder 40, that is also beyond the lower plane 24 of the tableware basket 20.

This extension of the side edges 43 of the tableware holder 40 can be limited to a central part of these side edges 43.

As is well illustrated in Figure 4, these lateral edges therefore allow to reflect the water jets (see arrow) coming from the windlass 21 arranged at the bottom, in the direction of the crockery elements supported on the tableware holder 40 .

In addition, central bars 44 intended to support the arches 412, 422 in the center of the tableware holder 40 may also comprise recesses or notches 45 (see in particular Figure 3 or Figure 13) to allow the passage of water jets .

These notches 45 can be made in the form of an arc of a circle in the vertical plane of each bar 44 so that a passage for the water jets is created in the direction of the dishes arranged on the tableware holder 40.

In order to obtain a uniform distribution of the tensions in the set of each arc 412, 422, the cross section of the profile of the arches 412, 422 varies between a base part of the arches, located near the bottom 24 of the basket for crockery 20 and a remote part, and for example the central part of each arch.

Therefore, the cross-section of the curved elements constituting the arches in the base part is larger than the cross-section of these same curved elements in the remote part of the base part of the curved elements.

More precisely, the width of the cross section, that is the distance between the flat wall 418 and the contoured wall 417, is increased in the base part of the arches 412, 422 with respect to the cross section located in the center of the arc 412, 422.

Although a profiled cross section in plane wing has been described for a curved element and that constitutes an arch of the tableware support structure, this specific cross section can also be applied to rectilinear elements or other curved elements of the support structure for crockery, and for example to the different bars 51 that allow to support the crockery on the crockery basket 20.

Finally, in order to improve the placement of large-sized tableware elements, of the large-diameter plate type, or even glass with a foot, the tableware basket comprises a maintenance element 440 near a tableware support area 40 in crockery position.

In the embodiment as illustrated in Figure 3, the dishware basket comprises three maintenance elements 440, 440 ’.

A first maintenance element 440 is disposed near a tableware support area 410, 420, and preferably between these two tableware support areas 410, 420.

This maintenance element 440 is adapted to be oriented according to several positions:

-

 a position separated from the support zones 410, 420 as illustrated in Figure 1;

-

 a position close to the first tableware support zone 410; Y

-

 a position close to the second of tableware support 420.

In this embodiment, the orientable element 440 may comprise battlement shapes 441, 442 (see in particular Figures 2 and 3).

These battlement shapes 441, 442 can have a flat bottom (form 442) or a circular bottom (form 441) adapted for the maintenance of different vessel shapes and sizes. Therefore, flat bottom battlements 442 are adapted to keep a glass without a foot and circular bottom battlements 441 are adapted to keep a glass standing.

As also illustrated in Figure 2, the orientation of this maintenance element 440 can be achieved thanks to an elastic coupling system in a fixing area 443. The maintenance element can therefore be constituted by a rilsanized wire having its ends two feet 444 adapted to pivot (for example by means of an interlocking system), to modify the orientation of this maintenance element 440.

Between the two feet 444 of the maintenance element 440, the curved curved wire is extended to make the different battlements 441, 442, at a height of the order of 50 to 70 mm above the plane P of the tableware holder 40.

So that it can be used with one or another of the tableware support areas 410, 420, this orientable maintenance element 440 is reversible to allow any use position.

In addition to its operating positions, the orientable maintenance element 440 could also be foldable and therefore occupy a substantially folded position in the plane of the bottom 24 of the dishware basket 20. This maintenance element 440 can also be removable.

In this embodiment, the tableware holder further comprises two other maintenance elements in the position of the tableware 440 ′ arranged in the front part of the tableware holder and across this tableware holder 40.

These maintenance elements 440 ′ are arranged in this case near an inclined surface 50 allowing glasses to be arranged.

A maintenance element 440 ’can be, for example, fixed, mounted on the front face of the dish basket. A second maintenance element 440 ’can be removed from the front face of the basket and foldable against the inclined surface 50.

As before, these 440 ’maintenance elements comprise battlements 441’ adapted to maintain a tall glass or the foot of a glass with a foot (see Figure 3).

It is noted that the whole of the description that has been previously made with respect to the dishware basket 20 is applied identically to the description of the basket for lower dishes 30.

Now, other embodiments of a tableware holder whose maintenance element in the tableware position has been modified to adapt to the support of large plates, generally larger than 26 in diameter, will be described in reference to Figures 9 to 13 cm.

The elements common to the embodiments described above, in particular in reference to Figure 3, will now not be described again.

As before, the dishware basket 20 comprises in this embodiment two plate support areas 410, 420.

In this embodiment, and not limitatively, the support means of the plates are constituted by the arches 412, 422 described above.

These arches 412, 422 are adapted to support the plates according to a first angle of inclination with respect to the vertical.

As indicated above, this angle of inclination is of the order of 0 to 5º with respect to the vertical.

A maintenance element in plate position 450, 450 'is disposed near the plate support area 410, and in this embodiment, near the two plate support areas 410, 420.

More precisely, the maintenance element in plate position 450, 450 'is disposed between the two plate support areas 410, 420.

As well illustrated in Figures 9 and 10, the maintenance element in plate position 450, 450 'is adapted to support in cooperation with the support means of the plate support area, which have the embodiment with the arches 412 of the plate support area 410, plates according to a second angle of inclination with respect to the vertical.

The position of these maintenance elements in plate position 450, 450 'allows the plates to be tilted better, so that the second angle of inclination is greater than the first angle of inclination defined above by the plate support structure by means of the arches 412.

As well illustrated in Figures 9 and 10, each maintenance element in plate position 450, 450 'comprises a series of rods 451, 451.

As described in reference to the first embodiment of Figure 1 and to the maintenance element in tableware position 440, the maintenance element in plate position 450, 450 'is orientable, for example by means of a fixing system 443 as described above, which implements an interlocking system.

For this, the series of rods 451, 451 ’is mounted on a pivoted structure 452, 452’ pivotally mounted on the dishware basket 20.

The maintenance element in plate position 450, 450 'is therefore at least adapted to adopt a position separate from the first plate support area 410 or a position close to this plate support area 410.

As illustrated well in Figures 9 and 10, the maintenance element in position of plates 450, 450'coopera to maintain the large diameter plates with the arches 412 of the first plate support area 410 when the maintenance element in the plate position it is in a separate position from this plate support area 410.

In this embodiment in which the maintenance element is placed between the plate support areas 410, 420, when the plate position maintenance element cooperates with the arches 412 of the first plate support area 410, it is at the same time in a separate position of this first plate support zone 410 and in contact with the second plate support zone 420.

As well illustrated in Figures 9 and 10, the maintenance element in position of plates 450, 450 'therefore comes into contact with a part of the curved and curved surface of the second plate support area 420, preferably near from the base of the arches 422 of this second plate support area 420.

This ensures the blocking of the maintenance element in plate position 450, 450 ’in a position separated from the first plate support area 410.

This arrangement ensures reliable maintenance of large format plates.

Obviously, although a cooperation of the plate support maintenance element 450, 450 'with the first plate support zone 410 has been described, identical cooperation can be performed, in the opposite direction orienting the plate support maintenance element 450, 450 ', with the second plate support area 420.

In this case, in the embodiment described in Figure 9, the rods 451 'are fixed with respect to the pivot structure 452' and form an angle of at least 45 ° with this pivot structure 452 '.

In the embodiment as illustrated in Figure 10, the rods 451 are articulated on the pivoted structure 452 of the maintenance element in plate position 450.

This second embodiment is described in more detail in reference to Figures 11A and 11B.

More precisely, the pivoted structure 452 is constituted in this case by a rilsanized wire folded at its ends 453 to allow a pivotal mounting on the fixing means 443 as described above.

Between these ends 453 extends a rilsanized wire 454 on which the rods 451 are pivotally mounted.

These rods 451 are in turn integral with a rilsanized wire 455 mounted by means of a grip system 456 on the rilsanized wire 454.

These rods 451 form an angle of approximately 45 ° with the rilsanized wire 455 and the rilsanized wire 454 of the pivot structure 452.

The grip system 456 allows the relative rotation of the rilsanized wires 454 and 455.

In order to limit the amplitude of the pivoting of the rods 451 around the rilsanized wire 454 of the pivoting structure 452, the wire 455 supporting the rods 451 comprises battlements 457 (see in particular Figure 11A).

These battlements 457 are intended to act together with battlements 458 provided in the length of the wire 454 of the pivoted structure 452.

More precisely, some battlements 457 are intended to come into contact with battlements 458 when the rods 451 are in a substantially perpendicular position and above the wire 454, which therefore extends opposite the mounting ends 453. This first position It is illustrated in particular in Figure 11B.

A second part of the battlements 457 of the wire 455 supporting the rods 451 is intended to be locked in the battlements 458 of the wire 454 when the rods 451 are perpendicular to the wire 454 but in the same direction as the mounting ends 453.

This second position pivoted 180 ° with respect to the first position is illustrated in particular in Figure 13.

In addition to the pivoting locking function of the rods 451, the battlements 458 of the pivoting structure 452 of the maintenance element in plate position 450 are adapted to keep the foot of a vessel.

This functionality is obtained, in particular, when the maintenance element in plate position 450 is in a central position, between the tableware support areas 410, 420, as illustrated in Figures 12 and

13.

Thanks to the arrangement of the rods 451 in the vertical plane containing the maintenance element in the plate position, these rods 451 do not bother for the arrangement of tableware elements as described above in the tableware support areas 410, 420, nor for the maintenance of vessels supported on the battlements 458 of the maintenance element in plate position 450.

Thanks to the presence of these rods 451, 451 ', it is possible to keep a large diameter plate inclined in each tableware support area 410, 420 so that the upper part of the plate cannot come into contact with the upper part of the wash tank or with a spray pinwheel arranged at the top, or even, as illustrated in Figure 8 in the case of the basket for lower dishes 30, with the separation wall 3.

In particular, the inclination of the plates can be of the order of 45 ° with respect to the vertical, allowing the large diameter plates, between 26 and 33 cm, not to exceed the maximum height of the dishware basket 20, and rest inside of the volume of the basket as defined in particular by the front face door 4.

Obviously, the present invention is not limited to the embodiments described above.

In particular, tableware basket 20 could comprise a single tableware support area 410 as described above.

On the other hand, this support area for tableware 410, and more particularly the arches 412 could also be made from rilsanized wires and not from molded plastic material.

In addition, the different elements of the dishware basket 20 described above for the different embodiments can be practiced independently of each other.

10 In particular, the maintenance elements in position of the plates, intended to keep the large plates in the crockery basket very inclined, can be used for other types of plate support, which do not necessarily include arches.

On the other hand, the structure of the plate support area that forms a curved and curved surface can be performed differently, without putting into practice the arches described above to keep the plates in grooves.
