Description

The invention relates to a Spülguthalter for a dishwasher, for receiving items to be cleaned, especially laboratory glassware, with an example circular shaped base part having a center opening for receiving an injector lance, and a plurality of starting from the base part extending, a support surface for the dishes to be washed providing webs.

With regard to the geometric design, there is an almost infinite number of variants of laboratory glassware. For example, volumetric flasks, laboratory bottles, Erlenmeyer flasks, round-bottomed flasks and / or the like, each with a different capacity, are used. The geometries of laboratory glassware differ in some cases significantly from one another, for example with regard to the neck and / or belly diameter, the presence of undercuts and / or threads, the size dimensions in the height direction and / or the like.

For automatic cleaning and / or disinfection of laboratory glassware, dishwashers are used, which usually have dishwashing containers for holding laboratory glassware in the particular embodiment of a laboratory dishwashing machine. The laboratory glassware for cleaning and / or disinfection usually with her glass neck down and the glass bottom up on a so-called injector lance is inserted, which has an injector at its upper end and at the lower end there is a support surface for the glass neck.

This bearing surface is typically provided by webs which extend in a star shape from a central base part. The base part has a central opening, through which the injector lance is guided in the final assembled state.

Although previously known Spülguthalter have proven in everyday practice, there is room for improvement. Thus, it is perceived by the user as disadvantageous that corresponding Spülguthalter must be used depending on the geometric design of laboratory glassware to be cleaned. For on the one hand, this requires the stockpiling of a corresponding amount of differently trained Spülguthaltern. And on the other hand, it requires a proper use of a corresponding logistics, so that in the intended use, a size-appropriate assignment of the available Spülguthaltern can take place to be cleaned laboratory glassware. It is not uncommon for this to be misaligned, so the laboratory glassware is not kept safe during cleaning or disinfection, which in the worst case can lead to damage or even breakage of the laboratory glassware. In this respect, the handling of previously known Spülguthalter is complicated and it is incorrect handling possible.

It is therefore based on the above, the object of the invention to provide a Spülguthalter, which allows a simplified handling.

To solve this problem, a Spülguthalter of the type mentioned is proposed with the invention, which is characterized in that the webs have a base close, first portion and an adjoining second portion, wherein the two web portions are aligned angled to each other.

The Spülguthalter invention has in departure from the prior art not star-shaped arranged on a base webs. The webs are formed according to the invention rather angled, each web has two sections which are angled aligned with each other. The two sections are in particular angled around the direction of the center opening axis to each other. This web configuration makes it possible to arrange washware holders of the type according to the invention arranged offset to one another on a washware carrier known from the prior art, so that adjacent washware holders do not interfere. The asymmetric design of the webs according to the embodiment of the invention allows a nested arrangement of Spülguthalter on a Spülgutträger.

The inventive geometry design of Spülguthalters therefore allows Spülguthalter collision-free to arrange on a common Spülgutträger, because the non-star-shaped webs are aligned with a corresponding positioning of the Spülguthalter on Spülgutträger gap to each other. This causes the further positive effect that also in departure from the prior art, a standard size for a variety of Spülgutgeometrien alike can be used. Because the Spülguthalter can be adjusted in terms of its receiving geometry of the largest possible Spülgutform in practical operation, because unlike star-shaped Spülguthalter two intended purpose arranged on a Spülgutträger Spülguthalter of the invention do not hinder each other. This is not because the asymmetrically formed webs intermesh with the gap, so that the items to be washed adjacent to a washing utensil carrier therefore lie nested one below the other. Thus, the previously required variety of variants with regard to the user-side to be stocked Spülguthalter is eliminated. Along with this, the incorrect operation due to wrong or incorrectly positioned Spülguthalter is avoided.

Overall, the Spülguthalter invention allows to replace all previous Spülguthalter variants by a universal asymmetrically shaped holder. Because of the asymmetrical design of Spülguthalters it is possible to use this for both small and large laboratory glassware. The Spülguthalter can be positioned in the intended use relative to him receiving items to be washed by turning, so that a collision with adjacent components, that is adjacent Spülguthaltern and / or components of Spülgutträgers is avoided. If the distance between adjacent Spülguthaltern smaller than the ridge lengths of the two Spülguthalter, there is still no collision of Spülguthalter, because they are due to their coordinated asymmetry evading each other aligned by the positioning of Spülgutträger.

Thus, the Spülguthalter is designed so that it can be optionally arranged in a first position and at least in a second position on Spülgutträger, wherein the Spülguthalter is rotated in the second position about the center opening axis compared to the first position by a predetermined angle. Preferably, the Spülguthalter can also be arranged at least in a further rotated about the center opening axis third position or even beyond, at least in one around the center opening axis even further rotated fourth position or in still other positions on Spülgutträger.

According to one embodiment, the Spülguthalter can optionally both in a first, in a rotated by 90 ° about the center opening axis second, rotated in a 180 ° about the center opening axis third and in a 270 ° to the Mittenöffnungsachse rotated fourth position on Spülgutträger be arranged.

In the case of use, the items to be washed, such as a laboratory glass, is placed upside down over an injector lance and placed on the webs of Spülguthalters, so that the Spülgüt stands on the webs. The webs, in particular the second sections of the webs, together provide a support surface for the items to be washed or laboratory glass. The ware or laboratory glass is or is thus on the edge of this support surface. In this case, the webs, in particular the second sections of the webs, are aligned in a substantially horizontal manner, in particular within a common support plane, in the case of a washware holder arranged on a washware carrier within a dishwasher.

It is provided according to a further feature of the invention that the second web portions are aligned tangentially to the respective base part. It is further provided that the second sections of adjacent webs are aligned at right angles to each other.

Due to this configuration, it is apparent that on the one hand there is an optimized support for items to be cleaned, and on the other hand that a collision-free arrangement of the items to be washed is allowed on a washware carrier, without collision both with respect to adjacent items to be washed and with respect to components of the items to be washed even.

It is provided according to a further feature of the invention that a web extension is arranged on one of the webs. This web extension has a first and a second section, wherein the second section is aligned angled to the first section.

The web extension is not based on the base of the Spülguthalters, but from a web of Spülguthalters. This results in a relative to the circumference of the circular-shaped base part comparatively large angle portion which is free of web or formed Stegfortsatzfrei. By means of this base-part-side gap, it is possible to position the items to be washed on a washware carrier in such a way that under certain circumstances otherwise disturbing attachments of the items to be washed or adjacent items to be washed may lie in the direction of the items to be washed come, so that a collision-free arrangement is allowed on the Spülgutträger.

According to a further feature of the invention it is provided that the first web portion of the web and the first portion of the web extension are formed at right angles to each other. This embodiment also serves to ensure a coordinated geometrical configuration of two items to be washed which are arranged adjacent to one another on a washware carrier.

It is provided according to a further feature of the invention that an opening is formed between adjacent webs. This breakthrough serves in the arrangement of a Spülguthalters on a Spülgutträger to be able to record the provided by a Spülgutträger water distribution pipes. The webs of Spülguthalters invention are aligned in the final assembled state so offset in the height direction to the water-bearing lines of the Spülgutträgers down so that the maximum height in the receiving space can be exploited by a recorded by a Spülguthalter dishes. In other words, the breakthrough causes the webs of the Spülguthalters in the case of use in the arrangement of Spülguthalters to a Spülgutträger is arranged substantially laterally of the water distribution pipe, the provided by the webs of Spülguthalters contact surface for the dishes is approximately equal to the top of the water distribution pipe. It towers above the top of the water distribution pipes in the height direction preferably only to such a small extent that contact of the edge of the webs of Spülguthalters resting dishes with the water distribution pipe is avoided.

It is provided in accordance with a further feature of the invention that the base part carries a ring part spaced therefrom in the height direction. This ring member serves to support wash ware with a comparatively small diameter, that is to say a diameter which is smaller than the diameter of the base part. Thus, the embodiment of the invention is not only suitable for being able to receive items to be cleaned with a diameter which is greater than the diameter of the base part. In this case, according to the invention, the ring part is provided in order to ensure a spacing from the base part, so that flushing liquid introduced into the washware in the intended cleaning process can flow off without hindrance. In order to additionally support this effect, it is provided according to a further feature of the invention, that the ring part has knobs on the upper side. On these knobs comes to be cleaned items to lie, the advantage of Noppenausgestaltung is that the contact surface between Spülguthalter and items to be cleaned is minimized, so that the remaining of the Spülguthalter and / or the items to be washed accumulating residual liquid is minimized is.

The invention further proposes a Spülguthaltersystem. The Spülguthaltersystem has a plurality of Spülguthalter the above-described type, which can be combined on the user side according to the modular principle either with each other. "Modular principle" in the context of the invention means that the user side a variety of Spülguthaltern of the type described above are stored, depending on the amount to be cleaned ware used and insofar can be used either by the user for equipping a Spülgutträgers. Here, the essential advantage of the system according to the invention is that a universal Spülguthalter is used, in contrast to the prior art so do not have to find different Spülguthalter use in their geometric dimensions. This reduces the cost of warehousing and logistics and also ensures that application error rates are minimized.

The Spülguthalter 1 of the invention is in FIG. 1 in a schematic-perspective view and in FIG. 2 shown in a top view.

As FIG. 1 can be seen, the Spülguthalter 1 has a base part 2, which may be circular as shown here approximately. The base part 2 provides a central opening 3, through which, in the intended use case, a connection point 18 provided by a washware carrier 14, which may be round or angular, protrudes. Furthermore, the center opening 3 serves to receive an injector lance 19 connected to a connection point 18, as can be seen for example FIG. 3 or 5 results.

The base part 2 carries a thereto spaced apart in the height direction ring member 11. In this case 11 supports 12 are provided for the spaced arrangement of the ring member. These supports 12 are on the ring part side in nubs 13, which are arranged on the upper side of the ring member 11.

As FIG. 1 and FIG. 2 can be seen, the Spülguthalter 1 further comprises a plurality of starting from the base part 2 extending webs 4. In the illustrated embodiment, a total of three such webs 4 are provided.

Each web 4 has a first web portion 5, which is formed basisteilnah, and a second web portion 6. The two web portions 5, 6 are angled aligned with each other, which results in a deviating from the prior art star-shaped web design deviating geometry.

As FIG. 1 and particularly FIG. 2 can also be seen, the first and second portions 5, 6 of the webs 4 are aligned with each other such that the second web portions 6 are aligned tangentially to the base part 2. Due to the bending of the second web portions 6 according to the invention relative to the first web portions 5, it is also clear that the second web portions 6 of adjacent webs 4 are oriented at right angles to each other.

One of the three webs 4 is further equipped with a web extension 7, which in turn also has a first section 8 and a second section 9. It is the second section 9 of the web extension 7 is aligned angled relative to the first section 8 of the web extension 7.

As FIG. 1 can also be seen, an opening 10 is formed between adjacent webs 4, which accommodates a water-carrying tube of a Spülgutträgers 14 in the final assembled state, as the other FIGS. 3 to 5 can be seen by two different embodiments.

The Spülguthalter 1 is formed as a one-piece injection molded part made of plastic. FIG. 3 shows a Spülgutträger 14. This is located in the intended use case within a washing compartment of a dishwasher, not shown in the figures. The Spülgutträger 14 has in the embodiment shown four square tubes 15, which are coupled via a common connecting pipe 16 fluidly with each other. The connecting pipe 16 carries a water connection 17, which is connected in the intended use case to a dishwasher-side water supply. In the operating case, flushing liquid can thus be introduced into the washware carrier 14 via the water connection 17, wherein the introduced water is distributed through the water connection 17 via the connecting pipe 16 into the square pipes 15.

The square tubes 15 are each equipped with connection points 18, to which injector lances 19 are screwed in the intended use case. Each of the injector lances 19 provides an injector nozzle at its end facing away from the connection point 18.

In the intended use case, a laboratory glass to be cleaned is placed upside down over an injector lance 19. The rinse water leaving the injector lance 19 via the injector nozzle in the intended use case thus ensures internal cleaning of the laboratory glass paned over the injector lance 19.

For a secure positioning of the laboratory glass relative to the injector lance 19 is an inventive Spülguthalter 1, as shown in FIG. 3 is shown on a first embodiment.

As can be seen from the presentation FIG. 3 results, is per junction 18 a Spülguthalter 1 provided. This is placed with its base part 2 on the respective connection point 18. The injector lance 19 extends through the central opening 3 of the base part 2 as well as the corresponding opening formed in the annular part 11th

The square tubes 15 come to lie in the openings 10 which are formed between adjacent webs 4 of a Spülguthalters. It is thus achieved a position-safe position of Spülguthalters 1 relative to the Spülgutträger 14.

The ridges 4 respectively provided by each rinse aid holder 1 serve to receive a rinsing product at the edge, so that a secure positioning of the ware by the rinse aid holder 1 relative to the injector lance 19 is provided.

Like a synopsis of Figures 3 . 4 and 5 results, the web design according to the invention of the Spülguthalters 1 causes that adjacent Spülguthalter 1 with respect to their webs 4 is not in the way, a web collision is thus avoided. The web geometry of the Spülguthalter is coordinated in the manner described above in such a way that adjacent Spülguthalter 1 are offset from each other in gap, so that webs 4 adjacent Spülguthalter 1 collision pass each other, that is, adjacent Spülguthalter 1 interlock.

In this case, the inventive design also allows a Spülguthalter 1 with respect to its respective Injektorlanze 19 about a formed by the injector lance 19 axis of rotation from the respective square tube 15 of the Spülgutträgers 14 can be added. In this case, due to the above-described web design rotated by 90 ° positions of the Spülguthalters 1 relative to the Spülgutträger 14 possible.
