Description

The present invention relates to a washing basket for dishwashers, the washing basket having a grid-shaped basket base and side walls formed from base bars and the side walls together with the basket base surrounding a basket interior of the washing basket and the basket base and / or the side walls having contact surfaces on an underside of the washing basket, which end in a support level of the washing rack.

In addition, the invention also relates to an arrangement with a dishwasher and a washing basket and a method for washing objects arranged in the interior of a washing basket in a dishwasher.

In the prior art, washing baskets of the generic type are used for washing dishes, glasses, cutlery and the like in dishwashers. In the industrial sector in particular, such washing racks can also be used for washing other items in dishwashers.

A wash basket of the type mentioned is z. B. in the EP 1 287 780 B1 shown.

It is the object of the invention to improve washing racks of the generic type in such a way that they contribute to the best possible washing result.

According to the invention, it is provided for this purpose that the bottom webs have angled web areas which, viewed in a sectional plane orthogonal to the contact plane, are arranged at least in some areas at an acute angle to the contact plane.

Due to the angled web areas of the bottom webs, the one in which

Dishwasher sprayed into the washing basket from below and deflected in a targeted manner, so that the items to be washed stored in the basket interior are exposed to washing liquid from as many different sides as possible. In this way, it is at least largely avoided that there are areas of the objects to be washed that are not exposed to washing liquid. Overall, the wash result is thus improved by the angled web area of the bottom webs. Washing baskets according to the invention can be used for washing dishes, glasses, cutlery, but also other objects in correspondingly suitable dishwashers. The washing racks according to the invention can be used accordingly both in the catering sector and in industrial production. Washing baskets according to the invention can, for. B. if they are used for washing plates, be equipped with special plate supports, known per se, on which plates are supported during the washing process. If they are present, these plate supports are then located in a manner known per se in the interior of the basket and can preferably be integrally formed or attached to the basket base.

The interior of the basket surrounded by the basket base and the side walls can be open at the top, that is to say on the side facing away from the basket base. However, washing baskets according to the invention can also be equipped with lids or the like, optionally latticed.

Basically, the washing baskets can be made of different materials. It is preferably a plastic wash baskets. The bottom webs and the side walls, preferably the entire washing basket, can or can be formed in one piece. The washing racks according to the invention can e.g. are manufactured by injection molding.

On the bottom of the basket and / or the side walls, there are support surfaces on the underside of the wash basket, with which the wash basket can be placed on one level. In this respect, the contact surfaces specify the contact plane of the wash basket in which the wash basket is in the normal position, that is to say with the basket bottom downwards, on a, usually horizontal, surface. The contact areas can be designed as punctiform, linear or otherwise. Even with a so-called point-like design, there is ultimately always a certain area available, so that the concept of the contact area is also permissible in this case.

The orthogonal cutting plane through the bottom webs with the angled web areas is in each case a cutting plane which is orthogonal to the contact plane. In this orthogonal sectional plane, each running through the bottom web with the angled web area, the angled web areas are arranged at least in some areas at an acute angle to the contact plane. Seen in this cutting plane, the bottom webs can be arranged completely at an acute angle to the contact plane. In this case, the bottom webs in this area consist exclusively of angled web areas.

In order to avoid flushing shadows, however, preferred variants of the invention provide that the bottom webs, viewed in the sectional plane orthogonal to the standing plane, are at least partially angled in themselves. It can be provided in the invention that the bottom webs, viewed in the cutting plane orthogonal to the contact plane, also have orthogonal web regions above or below the angled web regions, the orthogonal web regions, viewed in the cutting plane orthogonal to the contact plane, being arranged orthogonal to the contact plane. Overall, angled web areas thus describe an area of a base web which, viewed in a corresponding orthogonal sectional plane, is arranged at least in some areas at an acute angle to the contact plane. An orthogonal web area is one which, viewed in the corresponding orthogonal cutting plane standing orthogonally on the contact plane, is arranged orthogonally, that is, at a right angle to the contact plane.

As is known per se, an acute angle means an angle that is greater than 0 ° and smaller than 90 °, i.e. smaller than an orthogonal angle. In this sense, one could also say that the angled web areas are arranged at an angle or angled to the contact plane, the words angled or angled describing angles that are in the range between 0 ° and 90 °.

In case of doubt, the terms above and below refer to an operating position of the washing rack in which the contact plane is horizontal and the bottom of the basket forms the lower end of the washing basket.

The term of the lattice-shaped basket base describes that the basket base has free spaces or through-openings between the base webs through which e.g. the rinsing liquid can enter the basket interior through the basket bottom.

It is preferably provided that, viewed in the section plane orthogonal to the standing plane, one of the orthogonal web areas, preferably in each case, merges directly into one of the angled web areas.

Preferred variants of the invention also provide that, as seen in the cutting plane orthogonal to the contact plane, one of the orthogonal web areas encloses an obtuse angle with one of the angled web areas. As is known per se, an obtuse angle is an angle that is greater than 180 ° but less than 270 °.

In order that the rinsing liquid deflected at the angled web areas can achieve the maximum effect in the basket interior, it is preferably provided that the angled web areas are arranged below the basket interior. In other words, the angled web areas are not located in the area of the side walls of the wash basket.

Preferred variants of the invention provide that a bottom web has a sequence of angled web areas along its longitudinal extension. It is preferably provided that the angled web areas that follow one another in the sequence are arranged at a distance from one another in the direction of the longitudinal extension of the bottom web. It is also favorable if the angled web areas of the respective bottom web are angled in different directions.

The bottom webs can, seen in a plan view of the basket bottom or the support plane, run parallel to the side walls of the washing basket. The bottom webs can, as seen in said top view, but also run parallel to a diagonal or at a different angle to the side walls of the wash basket through the wash basket. Mixed forms of these are also possible. Preferred variants of the invention provide that at least some of the bottom webs jointly form a diamond-shaped pattern. There can also be base webs running parallel to the side walls as well as base webs forming a diamond-shaped pattern in a basket base. By means of bottom bars running parallel to the side walls, which extend further than the other bottom bars downwards in the direction of the support level, a cross-shaped structure can be created in the basket base, which can be used to move the corresponding means of transport of a dishwasher from below into this cross-shaped structure of the basket base intervene to transport the washing basket through a corresponding dishwasher. Such cross-shaped structures in basket floors are known per se.

In principle, angled web areas according to the invention can be formed on all of the above-mentioned bottom webs.

As is known per se, the wash basket can have a rectangular, in particular square, but also a differently shaped basic shape when viewed from above on the wash basket or on its support plane. The term rectangular or square basic shape also includes those embodiments in which the corners of this basic shape are rounded. In addition to the washing basket per se, the invention also relates to an arrangement with a dishwasher and with a washing basket according to the invention, the washing basket being arranged in the washing machine and washing liquid nozzles of the washing machine being arranged below the basket base and a respective washing liquid discharge direction of the respective washing liquid nozzles being directed towards the basket base. It is preferably provided that the washing liquid nozzles are arranged in a rotatably mounted washing arm of the washing machine, the washing arm then also being located below the basket base. In this arrangement, the washing liquid is sprayed from the washing liquid nozzles from below through the basket bottom onto the objects to be washed in the basket interior. In this case, a relatively large proportion of the total amount of washing liquid discharged by the washing liquid nozzles passes through the free spaces or through openings in the bottom of the basket without being deflected. However, if the rinsing liquid hits the angled web areas of the bottom webs, it is deflected there so that a multitude of different directions is formed in the basket interior, in which the rinsing liquid hits the objects to be washed and stored in the basket interior. As explained above, this achieves a particularly good washing result.

In addition, the invention also relates to a method for washing objects arranged in the basket interior of a washing basket according to the invention in a dishwasher, wherein the washing basket for washing the objects in the dishwasher is arranged via washing liquid nozzles of the dishwasher and washing liquid is sprayed from the washing liquid nozzles through the basket bottom into the basket interior is, with parts of the rinsing liquid being diverted from the angled web areas of the bottom webs into the basket interior.

The objects to be washed arranged in the basket interior can, as already stated above, be dishes, glasses, cutlery, but also other objects.

Fig. 1 shows, in a perspective view obliquely from above, a washing basket 1 in which the bottom webs 3 according to the invention have angled web regions 10, even if they are in FIG Fig. 1 so cannot be seen. As is known per se, the washing basket 1 has a lattice-shaped basket base 4 formed from base webs 3 and side walls 5. The side walls 5 and the basket base 4 together surround the basket interior 6 of the washing basket 1. The side walls 5 can, as shown in this exemplary embodiment, be partially perforated with openings. The basket interior 6 is open at the top in this embodiment. On the underside 7 of the side walls 5 and / or the basket base 4 there are support surfaces 8 which end in a support plane 9 of the washing basket 1. In the z. B. in Fig. 6 normal operating position of the washing rack 1 shown, the support level 9 is usually a horizontal plane. It can also be said that the contact areas 8 together span or define the contact plane 9.

The in Fig. 1 The washing basket 1 shown is a washing basket 1 specially designed for washing plates in dishwashers 2. In this exemplary embodiment, plate supports 21 are in itself on the bottom webs 3 A known manner, on which the plates can be leaned against in a manner known per se, so as to be able to stand on their edge in the washing basket 1 for the washing process. These plate supports 21 are of course optional and can, especially when other objects 19 such. B. glasses or cutlery to be washed, also omitted.

The washing basket 1 shown here has a square basic shape with rounded corners. As already explained at the beginning, washing racks 1 according to the invention can of course also be designed with rectangular or other basic shapes, optionally with rounded or non-rounded corners. Rinsing baskets 1 according to the invention are advantageously made from plastic. It can be provided that all components of the washing rack are connected to one another in one piece. According to the invention washing baskets 1 can, for. B. be manufactured by injection molding.

Fig. 2 shows a view from above of the top side 7 of the washing basket 1 Fig. 1 . In Fig. 2 is the contact plane 9 in the plane of the sheet. The basket interior 6 is delimited at the bottom by the basket base 4, which consists of a plurality of base webs 3 with free spaces or through openings between them. The bottom webs 3 can be designed to run differently. In the exemplary embodiment shown here, there are bottom webs 3, which in their longitudinal extension 15 run parallel to one of the side walls 5. Such parallel bottom webs form the cross-shaped structure already mentioned at the beginning, which can be used to transport the washing rack 1 through a dishwasher 2. In the exemplary embodiment shown here, however, some of the bottom webs 3 also form a diamond-shaped structure. In this exemplary embodiment, the plate supports 21 are also formed at the crossing points of this diamond-shaped structure. All of these bottom webs 3 can have angled web regions 10 according to the invention. As already stated at the outset, these can be arranged at a distance from one another in the direction of the longitudinal extension 15 of the respective bottom web 3. The angled web areas 10 are advantageously below the basket interior 6 and not arranged under the side walls 5. In the exemplary embodiment shown, both the bottom webs 3, which run diamond-shaped to one another, and the bottom webs 3, which run parallel to the side walls 5, each have angled web regions 10. In addition, in all four corner areas of the basket bottom 4, along the respective diagonals with respect to the respective rounded corners of the side walls 5, inwardly displaced bottom webs 3 with each angled web regions 10 are provided, as shown in particular in FIG Fig. 2 are marked at the bottom left. These bottom webs 3 arranged in the corner areas enclose an orthogonal angle with one another when viewed from above on the underside 7 of the wash basket 1.

The Figures 3, 4 and 5 now show, by way of example, sections 11 orthogonal to the support plane 9, sections through base webs 3 with angled web regions 10. The in Fig. 2 entered cutting planes 11 are orthogonal to the plane of the sheet Fig. 2 , which also forms the standing level 9. Fig. 3 shows the corresponding orthogonal section plane 11 along section line AA Fig. 2, Fig. 4 along the section line BB and Fig. 5 in a section line CC Fig. 2 . The standing plane 9 and the respective orthogonal cutting planes 11 are in the Figures 3, 4 and 5 each shown. In the Figures 3, 4 and 5 the orthogonal cutting planes 11 each lie in the plane of the sheet. The contact planes 9 are orthogonally so at right angles to the sheet plane. In all three Figures 3, 4 and 5 it can be clearly seen that the bottom webs 3 each have angled web regions 10 which, viewed in the respective sectional plane 11 orthogonal to the contact plane 9, are at least partially arranged at an acute angle 12 to the contact plane 9. In all three figures it can also be seen that these bottom webs 3 with the angled web areas 10, viewed in the respective orthogonal sectional plane 11, are at least partially angled, i.e. have two areas which are angled to one another. In the exemplary embodiments shown here, these areas are each the angled web regions 10 and the orthogonal web regions 13. The angled web regions 10 are each seen in the respective orthogonal sectional planes 11 at an acute angle 12 to Support plane 9 is arranged, wherein different angled web areas 10 can also be arranged at different acute angles 12 to the support plane 9. The orthogonal web areas 13 run, seen in the respective orthogonal cutting plane 11, orthogonally to the contact plane 9. This is also shown in FIG Figures 3, 4 and 5 clearly visible. In all three figures it is also the case that, viewed in the respective orthogonal sectional plane 11, the respective orthogonal web area 13 encloses an obtuse angle 14 with the respective angled web area 10. The wall thicknesses of the bottom webs can generally speaking z. B. in the range from 1mm to 10mm, preferably from 2.5mm to 4mm. The length extension 24 of the angled region 10 to the length extension 25 of the orthogonal web region 13 can be in a ratio of 10: 1 to 1:10, preferably 3: 1 to 1: 3, the length extensions 24, 25 always in a normal, i.e. in all directions orthogonal, on the contact plane 9 running direction are measured. The angles 12 between the angled web areas 10 and the contact plane 9 in the said orthogonal cutting planes 11 are advantageously in a range between 30 ° and 85 °, particularly preferably in a range between 60 ° and 80 °. The length of an angled web region 10, viewed in the respective direction of the longitudinal extension 15 of the respective bottom web 3, is advantageously at least 5 mm. All of the preferred value ranges mentioned can be used in the most varied of embodiments of the invention.

In the Figures 3, 4 and 5 rays are also drawn in by way of example, which represent rinsing liquid 20 deflected at the bottom webs 3 and in particular at the angled web regions 10.

Fig. 6 shows an example of an arrangement with a dishwasher 2 and a washing rack 1 according to the invention arranged therein, the dishwasher 2 being shown only in a very simplified manner. The dishwasher 2 can be designed as is known per se in the prior art. Fig. 6 shows a vertical section through this arrangement along a diagonal through the in Fig. 1 and 2 shown Washing rack 1, which is supported with its contact surfaces 8 on corresponding rails 22 of the dishwasher 2. The operating position of the washing rack 1 is thus shown in which the washing process in the washing machine 2 is usually carried out. In this operating position, the contact plane 9 of the washing rack 1, which is predetermined by the contact surfaces 8, runs in a horizontal plane. In the basket interior 6 are in Fig. 6 Plate shown in a highly schematic section as objects 19 to be washed. In the Fig. 1 visible plate supports 21 on which these plates or objects 19 are supported are shown in Fig. 6 not to see. The washing liquid nozzles 16 are located below the basket bottom 4, which in the exemplary embodiment shown here are embodied in a rotatably mounted washing arm 17 of the dishwasher 2. The rinsing liquid delivery directions 18 of the respective rinsing liquid nozzle 16 are directed towards the bottom of the basket, so that the washing liquid 20 passes from below through the lattice-shaped basket bottom 4 into the basket interior 6 during the washing process, in order to wash the items 19 there. A method according to the invention is thus shown for washing objects 19 arranged in the basket interior 6 of a washing basket 1 according to the invention in the dishwasher 2, the washing basket 1 being arranged for washing the objects 19 in the dishwasher 2 via the washing liquid nozzles 16 of the dishwasher 2 and the washing liquid 20 is sprayed from the washing liquid nozzles 16 through the basket bottom 4 into the basket interior 6, parts of the washing liquid 20 being diverted from the angled web regions 10 of the base webs 3 into the basket interior 6. Other parts of the washing liquid 20, which do not come into contact with the base webs 3 when penetrating the basket bottom 4, reach the basket floor interior 6 without being deflected. Overall, this means that the objects 19 to be washed arranged in the basket interior 6 are hit by the washing liquid 20 from different directions, which leads to a very good washing result overall.

Fig. 7 shows again a view from above of the washing basket 1 of Fig. 1 and 2 , only a part of which is shown enlarged. The direction arrows 23 show the directions in which the respective in this area of the base web 3 formed angled web areas 10 are angled out. This illustrates, on the one hand, that in preferred embodiments such as the one shown here, the angled web regions 10 which follow one another in the sequence are arranged at a distance from one another in the direction of the longitudinal extension 15 of the bottom web 3. In addition, the representation in Fig. 7 As an example, it can be seen that the angled web areas 10 of the respective bottom web can be angled in different directions from one another. In the exemplary embodiment shown here, the successive web regions 10 of the bottom webs 3 running parallel to the side walls 5 are always alternately angled or inclined in mutually opposite directions 23. In the case of the bottom webs 3 arranged in a rhombic shape, this embodiment provides that two adjacent angled web areas 10 are angled in the same direction 23 and the angled web areas 10 which then follow in the direction of the longitudinal extension 15 of the respective bottom web 3 are inclined in the other direction , as can also be seen from the directional arrows 23.
