The bridges are inclined so as to form a diamond-shaped cross-section.

Description

The invention relates to an insertable with cutlery and / or with small dishes insert for a dish rack, namely a cutlery basket for a dishwasher, which is operable with at least a partial program drying and a program program purging comprehensive cleaning programs, and a crockery basket with at least one with cutlery and / or with cutlery basket and a dishwasher with at least one with cutlery and / or with crockery stocked cutlery basket.

From the German patent application DE 44 14 347 A1 a method for operating a dishwasher is known, which can be actuated with at least one sub-program drying and a subprogram purging comprehensive cleaning programs.

From the German patent DE 36 41 020 C1 a device is known in a dishwasher for cleaning and drying of cutlery and small crockery, which allows an improvement in the drying performance over previous devices. In this case, at least one crockery basket has a cutlery basket which can be inserted therein, with apertures for the passage of flushing liquid present in each case in the cutlery basket bottom and the cutlery basket side walls. In addition, a tray with further breakthroughs for attachable cutlery and / or holders or shots for small dishes in the cutlery basket bottom of the dish basket can be used or lidded on the cutlery basket placed. The openings thus arranged in the side walls, the cutlery basket bottom and the cutlery basket cover of the cutlery basket and / or of the tray are delimited in each case by straight webs which intersect at right angles in a plane.

From the German Utility Model DE 76 05 749 U1 a device is known in which the webs, which limit the openings of the cutlery basket bottom, have inclined web portions. These web sections start from the level of the cutlery basket floor and unite outside this level. The advantage of this - but difficult to produce - cutlery basket is compared to the horizontally extending webs in an improved drop flow only from the cutlery basket bottom of the cutlery basket.

From the German patent application DE 198 20 979 A1 a device for dishwashers is known in which belonging to a cutlery tray and coupled to each other webs have higher and deeper points in the manner of a pyramid to improve the drying performance of the cutlery tray. In the German Offenlegungsschriften DE 195 40 610 A1 and DE 195 40 611 A1 are - also referred to as Etageren - shelves for baskets in a dishwasher described, each of which can be used as an insert for cleaning and drying of cutlery and / or small crockery firmly or movably connected to the crockery basket and / or loosely arranged.

The known devices all have the disadvantage that often rinsing liquid - for example, on a horizontal surface - remains, which does not run independently, but must dry. Leaning cutlery are therefore still wet even after the drying phase of a cleaning program usually on the shaft. In addition, a cutlery basket and / or other devices disadvantageously reinforced in the corners of each rectangular configured openings or openings where the cutlery usually present, that is, there are a variety of "berthing" for the rinsing liquid, which complicate the drying or prolong the drying phase and lead to the formation of drying spots on the cutlery.

The cutlery basket of PCT application WO 89/00022 A1 has cutlery holders and cutlery supports for storing cutlery to be washed and dried. The cutlery supports are provided with differently profiled bearing surfaces and / or different support heights. The cutlery supports are arranged to form cutlery support groups in alternating sequence in the cutlery basket. The cutlery of a cutlery tray group are formed with sawtooth shaped bearing surfaces and the cutlery of the other cutlery tray group with cut-shaped, flat bearing surfaces for the cutlery, the cut-shaped, flat cutlery cushions have the larger support height.

The Bestecktrockner the German disclosure DE 15 03 780 A1 comprises a housing part and a housing lower part, which are quiver-like plugged together with a horizontal plane of separation. The upper housing part has a top open compartment partition and a bottom end with arranged in this drain openings. To form different deep pockets, the bottom end for the compartmentalization extends in different parallel planes.

The invention is based on the object to be equipped with cutlery and / or small crockery insert for a crockery basket, namely a cutlery basket for a dishwasher, through which compared to known solutions additionally improved drying result for the cutlery and / or for the small crockery is achievable.

This object is achieved in a dishwasher of the type mentioned above in that the can be equipped with cutlery and / or with crockery insert for a crockery basket, namely a cutlery basket for a dishwasher, which is operable with at least a partial program drying and a program program purging comprehensive cleaning programs, wherein the cutlery basket has a plurality of openings for the passage of rinsing liquid, which are bounded by in a plane at intersections intersecting webs, the cutlery basket as means that cause problem areas in the cutlery basket, the drainage of drops of a rinsing liquid, provides that the openings in each case in the region of the crossing points are formed rounded by radii. Furthermore, the webs, which have inclined surfaces around their respective vertical plane and which have a diamond-shaped cross-section, form the cutlery basket bottom and / or the cutlery basket cover of the cutlery basket.

Other developments of the invention are specified in the subclaims.

Starting from a device of the type mentioned above means are formed on a can be fitted with cutlery and / or small dishes cutlery basket for draining drops of a rinsing liquid, which cause the drainage of drops of a rinsing liquid in problem areas of the cutlery basket. These agents cause liquid droplets to run off their own accord, and thus the formation of undesirable drying spots on the cutlery pieces and / or the small crockery is prevented. An even better drying performance and a shortening of the drying phase than in known devices is the result.

The cutlery basket has a plurality of openings for the passage of the washing liquid, which are bounded by in a plane at intersections intersecting webs. The webs are formed inclined so that they each have a diamond-shaped cross-section. Due to the diamond-shaped profile of the inclined webs formed at the crossing points a kind of double pyramid. Due to the diamond-shaped profile and the resulting at the crossing points double-pyramidal profile, the rinsing liquid - especially at the critical points - via the existing on all sides of the diamond or double pyramid sloping surfaces run down automatically. This avoids the rinsing liquid remaining on horizontal surfaces and at the numerous landing points, especially at the crossing points. Overall, results in such a designed cutlery basket over known solutions significantly improved drying results for the given in the cutlery basket parts - especially cutlery and / or small dishes. The adverse increased wetting in known applications at the numerous berthing and especially in the corners of the individual openings or openings is mitigated by in the cross-section diamond-shaped inclined ridges, which improves the drying and shortening the drying phase and the emergence of drying spots on the cutlery prevented.

Furthermore, the openings of the cutlery basket are each rounded off in the region of the crossing points by radii. As a result, the rinsing liquid can flow even better through the openings which are rounded off in the "corners", which advantageously accelerates the drying of the cutlery parts and / or small dishes, which are usually located at the openings in the "corners" -that is problem zones-during the drying phase.

According to an alternative, but equally favorable development of the invention, the cutlery basket constructed with cutlery basket compartments separated by partitions has at least two cutlery basket compartments with cutlery basket bottoms arranged at different heights for setting different cutlery parts and / or different small crockery. Overall, results in such a designed cutlery basket over known solutions significantly improved drying result for the cutlery basket given cutlery and / or small dishes. The cutlery and / or the small dishes can be adjusted depending on their length / size / shape in the cutlery tray with associated Besteckkorbboden at the appropriate height so that they stand up on the cutlery basket floor and no longer need to be hung. The self-draining flow of rinse liquid drops that would otherwise lead to the unwanted dry spots is supported by this simple yet effective measure. The hanging especially the small parts in a cutlery basket cover, which causes the mentioned drainage problems for the drops eliminated by the cutlery basket compartments with different heights basket cutlery.

According to a further embodiment of the invention, the heights of the cutlery basket bottoms of the cutlery basket are adaptable to the length and / or the size of the cutlery parts and / or the small crockery. As a result, depending on the requirements, sections which are partially adapted in the useful height are created as variable cutlery basket compartments which can be combined to form a variably configurable cutlery basket for a wide variety of cutlery items and / or for a wide variety of small crockery.

The cutlery basket compartments thus form a cutlery basket, which has a different useful height having cutlery basket bottom by the cutlery basket bottoms.

The object of the invention will be explained in more detail with reference to an embodiment shown in FIGS.

a second variant of an insert with a greatly simplified side view of a cutlery basket with multiple cutlery basket compartments to improve the drying performance according to the subject invention.

The Fig. 1 and the Fig. 2 show only one - for the representation of the principle of the invention but sufficient - section of the use to improve the drying performance. This can be equipped with cutlery and / or small crockery insert for a dish rack is a cutlery basket 13 for a dishwasher. The cutlery basket 13 may be loosely arranged in the dish rack or attached thereto fixedly or movably. The basic structure of a cutlery basket with side walls, cutlery basket bottom and / or cutlery basket cover corresponds to that in the German patent DE 36 41 020 C1 described use. Also, the use of the use of means according to the subject invention as a stocked with cutlery and / or with small dishes shelf - a storage rack - is possible.

The section of the cutlery basket 13 according to the prior art in the Fig. 1 comprises two longitudinal webs 1 and 2 and two transverse webs 3 and 4, which can form the cutlery basket bottom and / or the cutlery basket cover of a cutlery basket 13. In this case, the longitudinal webs 1 and 2 intersect with the transverse webs 3 and 4 at four crossing points 5, 6, 7 and 8 and thereby define an opening 9, which forms an opening for the passage of rinsing liquid 10.

The intersecting webs 1 to 4 are each at the crossing points 5 to 8 - of which the Fig. 1 an intersection point 7 by way of example in the view of the cross section or the profile shows - preferably inclined downwards in the manner of a cone 11 formed to improve the drying result for the cutlery and / or for the small crockery over the known cutlery baskets with straight webs. The Fig. 1 shows still existing problem areas where rinsing liquid 10 remains despite inclined ridges and can not drain by itself. These are above all the horizontal surfaces of the cutlery basket 13 and the corners of the individual openings 9, in which the cutlery basket is increasingly wetted and to which the parts create.

Therefore, according to the Fig. 2 formed the webs 1 to 4 inclined so that they each have a diamond-shaped cross-section, wherein they are shown at the intersection points 5 to 8 - of which again only the intersection point 7 is exemplified in the view of the cross section or the profile - a profile like a Double pyramid 12 have. This optimizes the Drying result and the time for the drying phase by the rinsing liquid 10 is pulled over all oblique surfaces of the rhombus down - indicated by the arrow -, that can flow off by itself. The improvement in drying is additionally assisted by the opening 9 which is rounded off in the region of the crossing points 5 to 8 by radii 23 and which is shown as representative of the design of all other openings in the cutlery basket 13. The moistened with rinsing liquid landing in the "corners" are no longer available for reasons of runoff down, on the cutlery basket leaning cutlery and / or small dishes are rather dry. The rapid and independent derivation of the rinsing liquid due to the inclined cross-section in a diamond shape inclined ridges and the reduction of the berths due to the rounded openings not only optimize the drying performance, but also advantageously improve the cleaning performance of a rinse and drying program of a dishwasher and prevent the formation of drying spots on the cutlery.

The Fig. 3 shows another variant of the device with means for improving the drying performance. The facility includes - as well as the Fig. 1 and the Fig. 2 - An insert that is designed as a cutlery basket 13 for equipping with cutlery and / or with small dishes - in the example chosen with spoons 14 and 15 different length or size - and loosely mounted in a dishwasher in a dish rack or fixed or movably attached thereto. The basic structure of a cutlery basket 13 with side walls, cutlery basket bottom and / or cutlery basket cover also corresponds to that in the German patent DE 36 41 020 C1 described use.

The cutlery basket 13 comprises in the example selected a total of three cutlery basket compartments 16, 17 and 18, which are delimited from each other by two vertically extending partitions 19 and 20. In principle, the cutlery basket can also have a different number - but at least two separate - compartments. According to the invention, at least two cutlery basket compartments, for example the cutlery basket compartments 16 and 17 or 17 and 18, have cutlery basket bottoms 16 'and 17' or 17 'and 18' arranged at different heights. Thus, as shown, the long spoon 14 is placed in the cutlery basket tray 16 with associated cutlery basket bottom 16 'and longer payload so that it safely rests on the cutlery basket bottom 16'. Also, adjusting the spoon 14 in the Cutlery tray 18, the cutlery basket bottom 18 'is at the same level with the cutlery basket tray 16' is possible. In contrast, the cutlery basket compartment 17 located in the middle serves for receiving or for adjusting the short spoon 15, so that it also securely rests on the associated cutlery basket bottom 17 '.

The three cutlery basket compartments 16 to 18 preferably have cutlery basket bottoms 16 'to 18' located at different heights, so that different useful heights for the cutlery basket 13, which can be partially adapted in the individual sections, result. Overall created by the height of their individual cutlery basket floors 16 'to 18' of the cutlery basket compartments 16 to 18 a cutlery basket bottom with different effective height. This makes it possible to raise and lower the cutlery basket floor in selected sections, in order to optimize the drying result when fitting the cutlery basket, particularly with cutlery pieces and / or with small dishes of the most varied length, size, shape and so on. The drying improvement is achieved by the variable design of the insert according to the invention, in that the rinsing liquid drop outlet is favored by the formation of a cutlery basket base having different useful heights. The on the cutlery basket floors 16 'to 18' in any case upstanding cutlery and / or small dishes are rather dry. The rapid and independent discharge of the rinsing liquid to the corresponding cutlery basket compartments 16 to 18 with a suitable height of the associated cutlery basket bottoms 16 'to 18' not only optimizes the drying performance, but also advantageously improves the cleaning performance of a rinsing and drying program of a dishwashing machine.

The above-described agents according to the invention result in liquid droplets running off independently and thus preventing the formation of undesired drying spots on the cutlery parts and / or on the small dishes. An even better drying performance and a shortening of the drying phase than in known applications is the result.
