EP1337178B1 - Insert for a basket of a dishwasher - Google Patents

Abstract

An insert having openings for the penetration of dish washing liquid, limited by ridges in-plane crossing at crossing points, ridges are embodied according to the invention at the crossing points in such a sloped manner, that they are provided with a rhomb shaped cross-section. Due to the rhomb shaped profile of the ridges embodied in a sloped manner a type of double pyramid is formed, by which the dish washing liquid can autonomously run off downwards over the sloped planes provided on all sides of the rhombus, particularly in the critical locations.

Description

The invention relates to an insert for a dish rack of a dishwasher according to the preamble of claim 1.

From the German patent DE 36 41 020 is a use for a dish rack of a dishwasher for cleaning and drying of cutlery and small crockery known. 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 other openings for attachable cutlery and / or holders or shots for small dishes in the basket bottom of the dish basket can be used or on the cutlery basket. Cover-shaped placed. The thus arranged in the side walls, the bottom and the cover of cutlery basket and / or tray breakthroughs are each bounded by straight in a plane crossing straight webs.

From the German utility model DE 76 05 749 a cutlery basket 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 difficult-to-manufacture cutlery basket is in comparison to the horizontally extending webs in an improved drop drain from the bottom of the cutlery basket.

From the German patent application DE 198 20 979 For example, a cutlery tray for dishwashers is known, in which mutually coupled webs have higher lying and deeper points in the manner of a pyramid. In the German Offenlegungsschriften 195 40 610 and 195 40 611 are - also referred to as Etagèren - shelves for baskets in a dishwasher described, each fixed or movable connected as a use for cleaning and drying of cutlery and / or crockery with the crockery basket and / or can be arranged loosely.

From the EP 0 966 913 A2 discloses a method for rinsing, cleaning and drying dishes and cutlery in a program-controlled dishwasher, with which can be cleaned on silver arrangement. To accommodate the cutlery, the dishwasher has a cutlery drawer, which can be pulled out of the dishwasher with the door open for loading and unloading. For holding cutlery items, such as. As spoons, forks, knives, ladles, etc., the cutlery drawer is formed from a flat, basket-like frame in the basic dimensions of a dish rack, which preferably receives one or more flat basket inserts interchangeable. The basket bottoms of the basket inserts are designed like a sieve for a flow of rinsing liquid. The basket inserts have cutlery recordings, which consist of cutlery holders formed on the basket bottom of the cutlery drawer and separate cutlery supports, the cutlery holders being designed as toothed racks and the cutlery supports being strips with preferably sawtooth and / or blade-shaped contact surface surfaces. Advantageously, the cut-shaped cutlery supports only touch the cutlery at points, so that drops of water can not attach to the items to be washed, and the dishes can be cleaned and dried optimally without any formation of water stains and residual contamination.

Such a cutlery basket for a dishwasher is also from the WO 89/00022 known.

The profiles of the webs of known solutions all have the disadvantage that flushing liquid often remains on a horizontal surface in particular, which does not run off by itself but must dry off. Leaning cutlery parts are still wet on the shaft even after the drying phase of a cleaning program. In addition, a cutlery basket and / or other inserts are disadvantageously more heavily wetted in the corners of the individual rectangular apertures or apertures where the cutlery pieces are usually in contact, i. There are a variety of "moorings" for the rinsing liquid, which complicate the drying or extend the drying phase and lead to the formation of drying spots on the cutlery.

The invention is based on the object to provide an insert of the types described, by which over known solutions improved drying result can be achieved.

This object is achieved by the features of claim 1 according to the invention. Further developments of the invention are specified in the subclaims.

Starting from an insert with openings for the passage of rinsing liquid, which are bounded by in a plane intersecting points intersecting webs, the webs according to the subject invention 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 double-pyramid-shaped profile created at the crossing points, the rinsing liquid can run down independently, especially at the critical points, via the oblique surfaces existing on all sides of the rhombus or double pyramid. This avoids the rinsing liquid remaining on horizontal surfaces and at the numerous landing stages, especially at the points of intersection. Overall, results from the inventively designed use a comparison with known solutions significantly improved drying result for the given in the use of parts - especially cutlery and / or small dishes. The disadvantageous increased wetting in known applications at the numerous piers and especially in the corners of the individual openings or openings is mitigated by the present invention in cross-section diamond-shaped inclined ridges, which improves drying and reduces the drying phase and the emergence of drying spots on the Prevents cutlery.

According to the invention, the apertures of the insert 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 apertures rounded off in the "corners", which advantageously accelerates the drying of the cutlery pieces and / or small crockery which are usually present in the "corners" at the apertures during the drying phase.

According to further embodiments of the invention formed at the intersection points inclined webs with diamond-shaped cross-section preferably the cutlery basket bottom and / or the cutlery basket cover and / or the side walls of a cutlery basket, which can be equipped with cutlery and / or crockery. Also, the at the intersection points inclined webs formed with diamond-shaped cross-section stocked with cutlery and / or crockery tray - the Etagere - form.

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

FIG. 1

a detail of a well-known use with the cross-section of the webs at crossing points,

FIG. 2

the cutout of the use of FIG. 1 with designed in accordance with the subject invention cross section of the webs.

FIG. 1 and FIG. 2 show only one - for the representation of the principle of the invention but sufficient - a use of insert, for example, as a cutlery basket for equipping with cutlery and / or small dishes in a dishwasher in a dish rack loosely arranged or fixed or movable. The basic structure of a cutlery basket with side walls, bottom and / or cover corresponds to that in the German patent DE 36 41 020 described use. The use of the insert according to the subject matter of the invention as a stockable with cutlery and / or crockery tray - a Etagére - is possible.

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

The intersecting webs 1 to 4 are each at the crossing points 5 to 8 - of which the FIG. 1 an intersection point 7 exemplarily 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 the small crockery over the known inserts 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 mainly the horizontal surfaces of the insert and the corners of the individual openings 9, in which the cutlery basket is increasingly wetted and create the parts.

Therefore, according to the invention, as in FIG. 2 illustrated, the webs 1 to 4 formed inclined so that they each have a diamond-shaped cross-section, where they at the intersection points 5 to 8 - of which in turn only the intersection point 7 is exemplified in the view of the cross section or the profile - a profile have the nature of a double pyramid 12. This results in an optimization of the drying result and the time for the drying phase by the rinsing liquid 10 is pulled over all inclined surfaces of the rhombus down - indicated by the arrow -, ie, the rinsing liquid 10 can flow off by itself. The improvement in drying is additionally assisted by the opening 9 rounded in each case in the region of the crossing points 5 to 8 by radii 13, which is shown as representative of the design of all other openings of the cutlery basket. The wetted 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 dry faster. The rapid and independent discharge of the rinsing liquid 10 due to the cross-section a diamond shape having inclined ridges 1 to 4 and the reduction of the berths due to the rounded openings not only optimize the drying performance, but also improve the cleaning performance of a rinse and advantageously Drying program of a dishwasher and prevent the emergence of drying spots on the cutlery.
