DE 10 2010 016 754 B3 relates to a laundry treatment machine, such as a washing machine or a tumble dryer, with a drum rotatably mounted in a housing, the housing having a floor pan in the bottom area which is made of a non-corrosive material, which is a plate-like surface in the bottom area of the housing for collecting of leakage and / or condensate liquid, strips made of a material of higher rigidity for fixing foot elements are arranged at least on the longitudinal sides of the plate-like surface.

Aus DE 3644053 A1 ist eine Geschirrspülmaschine, eine Waschmaschine oder dergleichen mit einer Auffangwanne für Leckwasser bekannt. Die Auffangwanne für Leckwasser ist bei der Geschirrspülmaschine, der Waschmaschine oder dergleichen bodenseitig am Gerätegehäuse unterhalb der Funktionseinheiten, wie beispielsweise Pumpen, Magnetventile, Druckwächter und so weiter angeordnet.the end DE 3644053 A1 a dishwasher, a washing machine or the like with a drip tray for leakage water is known. In dishwashers, washing machines or the like, the collecting pan for leaking water is arranged on the bottom of the device housing below the functional units, such as pumps, solenoid valves, pressure monitors and so on.

EP 2 889 425 A1 offenbart eine Waschmaschine mit einem Gehäuse mit einer Bodenabdeckung aus Kunststoff und einem hydraulischen Waschsystem, wobei mindestens ein Teil von mindestens einem Hydraulikelement, ausgewählt aus den Waschflüssigkeitskanälen und den Pumpenmotoren in die Bodenabdeckung integriert ist. EP 2 889 425 A1 discloses a washing machine with a housing with a bottom cover made of plastic and a hydraulic washing system, wherein at least a part of at least one hydraulic element selected from the washing liquid channels and the pump motors is integrated into the bottom cover.

Aufgabe der Erfindung ist die Bereitstellung einer Waschmaschine, eines Wäschetrockners oder einer Geschirrspülmaschine mit einem Gehäuse und einem Bodenmodul aus Kunststoff, das allen auf das Modul wirkenden Kräften beim Betrieb des Gerätes standhält, möglichst viele Anbauteile für die Funktionseinheiten integriert und alle weiteren Eigenschaften eines üblichen Stahlblechbodens übernimmt. Eine weitere Teilaufgabe der vorliegenden Erfindung besteht in der akustischen Optimierung insbesondere im Vergleich zu einem Kunststoffboden, der im Stand der Technik bereits bekannt ist.The object of the invention is to provide a washing machine, a tumble dryer or a dishwasher with a housing and a base module made of plastic that withstands all forces acting on the module during operation of the device, integrates as many attachments as possible for the functional units and all the other properties of a conventional sheet steel base takes over. A further sub-task of the present invention consists in the acoustic optimization, in particular in comparison to a plastic floor, which is already known in the prior art.

Die vorgenannte primäre Aufgabe wird in einer ersten Ausführungsform gelöst durch eine Waschmaschine, einen Wäschetrockner oder eine Geschirrspülmaschine mit einem Gehäuse und einem Kunststoffboden aus einer plattenartigen Grundfläche im Bodenbereich des Gehäuses zum Auffangen von Leckage- und Kondensatflüssigkeit, wobei der einschalige oder mehrschalige Boden

  1. (a) integrale einstückige Befestigungen von Funktionseinheiten, insbesondere Laugenbehälterstoßdämpfer; Pumpen; Magnetventile; Steuerungselektronik; Füllbehälter für Waschmittel, Waschmitteladditive oder Reinigungsmittel; Sensoren; Wasserwächter; Schmutzwasserleitungen; Schläuche und/oder Kabel und/oder
  2. (b) integrale einstückige Gehäuse oder Gehäuseteile von Funktionseinheiten, insbesondere Wasch- und/oder Reinigungsmittelbehälter, Pumpengehäuse und/oder Steuerungsgehäuse
aufweist, dadurch gekennzeichnet, dass die Unterseite des Kunststoffbodens eine flächenoffene Wabenverrippung mit Zellstegen, die sich im Wesentlichen senkrecht zur Fläche des Bodens erstrecken, aufweist.The aforementioned primary object is achieved in a first embodiment by a washing machine, a tumble dryer or a dishwasher with a housing and a plastic base made of a plate-like base in the base area of the housing for collecting leakage and condensate liquid, the single-shell or multi-shell floor
  1. (a) integral one-piece fastenings of functional units, in particular suds container shock absorbers; Pump; Solenoid valves; Control electronics; Filling containers for detergents, detergent additives or cleaning agents; Sensors; Water guard; Sewage pipes; Hoses and / or cables and / or
  2. (b) integral one-piece housings or housing parts of functional units, in particular washing and / or cleaning agent containers, pump housings and / or control housings
characterized in that the underside of the plastic base has an open-surface honeycomb ribbing with cell webs which extend essentially perpendicular to the surface of the base.

Mit Hilfe der vorliegenden Erfindung ist es dementsprechend möglich, die vorgenannte Aufgabe zu lösen. Bedingt durch die Herstellung des Bodenmoduls aus Kunststoff ist es möglich, Bauteile von Funktionseinheiten direkt als integrale einstückige Befestigungen in das Bodenmodul zu integrieren. Wird das Bodenmodul beispielsweise im Spritzgussverfahren hergestellt, so lassen sich beispielsweise Laugenbehälterstoßdämpfer; Pumpen; Magnetventile; Steuerungselektronik; Füllbehälter für Waschmittel, Waschmitteladditive oder Reinigungsmittel; Sensoren; Wasserwächter; Schmutzwasserleitungen; Schläuche und/oder Kabel direkt in die Bodenplatte integrieren.Accordingly, the present invention makes it possible to achieve the aforementioned object. Due to the fact that the floor module is made of plastic, it is possible to use components of functional units directly as integral ones integrating one-piece fixings into the floor module. If the floor module is manufactured, for example, by injection molding, then, for example, tub shock absorbers; Pump; Solenoid valves; Control electronics; Filling containers for detergents, detergent additives or cleaning agents; Sensors; Water guard; Sewage pipes; Integrate hoses and / or cables directly into the base plate.

In gleicher Weise können auch Gehäuse oder die Gehäuseteile von Funktionseinheiten wie beispielsweise Wasch- und/oder Reinigungsmittelbehälter, Pumpengehäuse oder Steuerungsgehäuse in den Kunststoffboden integriert werden.In the same way, housings or the housing parts of functional units such as washing and / or cleaning agent containers, pump housings or control housings can also be integrated into the plastic base.

"Integral einstückig" im Sinne der vorliegenden Erfindung bedeutet, dass die Funktionseinheiten, Gehäuse oder Gehäuseteile ebenfalls aus Kunststoffmaterial gefertigt sind und entweder in einem einzigen Arbeitsgang als Bestandteile des Kunststoffbodens gefertigt sind oder in einem oder mehreren nachträglichen Arbeitsgängen aus Kunststoffmaterial an dem Kunststoffboden abgeformt sind."Integrally in one piece" within the meaning of the present invention means that the functional units, housing or housing parts are also made of plastic material and are either made in a single operation as components of the plastic base or are molded from plastic material on the plastic base in one or more subsequent operations.

In der Fig. 1 sind schematisch Lagerbuchsen in Aufnahmen der Trommelstoßdämpfer, Aufnahmen der Standfüße, seitliche Abtropfwände, Gehäuse der Wasserpumpe, Aufnahmen für einen Schwimmer, Gehäuse für die Steuerungselektronik, Waschmittelbehälter sowie eine Schmutzwasserleitung in die Bodenplatte integriert.In the Fig. 1 Bearing bushings are schematically integrated into the drum shock absorber mounts, the feet mounts, side drip walls, the water pump housing, mounts for a float, housing for the control electronics, detergent container and a dirty water pipe in the base plate.

Dementsprechend besteht eine besondere Ausführungsform der vorliegenden Erfindung darin, dass der Boden an den Längsseiten der plattenartigen Fläche Bereiche zur Festlegung von Fußelementen aufweist. So wird das Gehäuse weitgehend von der Unterlage akustisch entkoppelt.Accordingly, a particular embodiment of the present invention consists in the fact that the bottom has areas for fixing foot elements on the longitudinal sides of the plate-like surface. In this way, the housing is largely acoustically decoupled from the base.

In einer weiteren Ausführungsform der vorliegenden Erfindung ist die Waschmaschine, der Wäschetrockner oder die Geschirrspülmaschine dadurch gekennzeichnet, dass das Gehäuse eine Abwasserpumpe oder eine Umwälzpumpe aufweist, die einstückig an dem Boden angeformt ist. Hiermit ist eine hervorragende Schalldämpfung ebenso verbunden, wie die zusätzliche Materialeinsparung eines Kunststoff-Gehäuses der Pumpe, das aufwendig an dem Boden befestigt werden müsste.In a further embodiment of the present invention, the washing machine, the tumble dryer or the dishwasher is characterized in that the housing has a waste water pump or a circulation pump which is integrally formed on the base. This is associated with excellent sound attenuation as well as the additional material savings of a plastic housing of the pump, which would have to be attached to the floor in a complex manner.

In der Fig. 1 ist darüber hinaus auch eine der notwendigen Wasserabtropfwände dargestellt, die in diesem Fall einstückig an dem Kunststoffboden angeformt ist. Auch hiermit ist eine erhebliche Einsparung an Arbeitsschritten verbunden.In the Fig. 1 one of the necessary water drip walls is also shown, which in this case is integrally formed on the plastic base. This, too, is associated with a considerable saving in work steps.

Erfindungsgemäß weist die Unterseite des Kunststoffbodens eine flächenoffenen Wabenverrippung mit Zellstegen auf, die sich im Wesentlichen senkrecht zur Fläche des Bodens erstrecken. In der Fig. 1 ist diese Wabenverrippung an einer Seitenwand erkennbar.According to the invention, the underside of the plastic base has an open-surface honeycomb ribbing with cell webs which extend essentially perpendicular to the surface of the base. In the Fig. 1 this honeycomb ribbing can be seen on a side wall.

In der Fig. 2 ist erkennbar, dass nicht nur die Unterseite des Kunststoffbodens, sondern auch eine seitliche Wasserabtropfwand eine entsprechende Wabenverrippung aufweisen kann.In the Fig. 2 it can be seen that not only the underside of the plastic floor, but also a lateral water drainage wall can have a corresponding honeycomb ribbing.

Dementsprechend ist es eine besondere Ausführungsform der vorliegenden Erfindung darin dadurch gekennzeichnet, dass die Wabenverrippung die Unterseite des Kunststoffbodens teilflächig oder vollständig bedeckt. Die Wabenverrippung kann somit auf die Bereiche des Bodens erstreckt werden, in denen eine Versteifung des Bodenmoduls oder eine verbesserte Akustik notwendig oder sinnvoll ist.Accordingly, a particular embodiment of the present invention is characterized in that the honeycomb ribbing partially or completely covers the underside of the plastic floor. The honeycomb ribbing can thus be extended to those areas of the floor in which stiffening of the floor module or improved acoustics is necessary or useful.

Bekanntermaßen hat sich die hexagonale Struktur einer Wabenkammer als besonders vorteilhaft bewiesen, so dass auch erfindungsgemäß diese Ausführungsform besonders bevorzugt ist.As is known, the hexagonal structure of a honeycomb chamber has proven to be particularly advantageous, so that this embodiment is also particularly preferred according to the invention.

Kumulativ oder alternativ kann die Wabenverrippung auch in Form einer so genannten Voronoi-Struktur vorhanden sein, um besondere strukturelle Bereiche des Kunststoffbodens zu versteifen. Als Voronoi-Struktur bezeichnet man bekanntermaßen eine Zerlegung des Raumes in Regionen, die durch eine vergebene Menge an Punkten des Raumes bestimmt werden. Jede Region wird genau durch ein Zentrum bestimmt und umfasst alle Punkte des Raumes die in Bezug zur euklidischen Metrik näher an dem Zentrum der Region liegen als an jedem anderen Zentrum. So können durch entsprechende Berechnungen Regionen des Kunststoffbodens für eine Wabenverrippung festgelegt werden, die einer besonderen strukturellen Stärkung bedürfen.Cumulatively or alternatively, the honeycomb ribbing can also be present in the form of a so-called Voronoi structure in order to stiffen special structural areas of the plastic floor. As is well known, a Voronoi structure is a division of space into regions that are determined by a given set of points in space. Each region is precisely defined by a center and includes all points in space which, in relation to the Euclidean metric, are closer to the center of the region than to any other center. Corresponding calculations can be used to determine regions of the plastic floor for honeycomb ribbing that require special structural reinforcement.

Neben der Unterseite des Kunststoffbodens ist es selbstverständlich auch möglich, die oben definierte Wabenverrippung auch auf der Außenseite der Wasserabtropfwände einzurichten, wobei auch hier eine vollständige oder teilweise Bedeckung der Außenseite möglich ist.In addition to the underside of the plastic base, it is of course also possible to set up the honeycomb ribbing defined above on the outside of the water drainage walls, with complete or partial coverage of the outside being possible here as well.

Der erfindungsgemäße Kunststoffboden kann auch aus einem oder mehreren, gleichen oder verschiedenen thermoplastischen oder duroplastischen Kunststoffen hergestellt werden. Besonders bevorzugt im Sinne der vorliegenden Erfindung sind thermoplastische Kunststoffe, da diese sich im Spritzgussverfahren hervorragend für die Zwecke der vorliegenden Erfindung eignen. Besonders bevorzugt im Sinne der vorliegenden Erfindung wird ein Polyolefin, insbesondere Polypropylen eingesetzt, das gegebenenfalls mit Fasern gefüllt ist. Besonders bevorzugt im Sinne der vorliegenden Erfindung ist ein Füllgrad des Kunststoffs im Bereich von 20 bis 40 Gew.%, bezogen auf die Gesamtmasse an Kunststoff und Fasern.The plastic floor according to the invention can also be produced from one or more, identical or different thermoplastic or thermosetting plastics. Thermoplastic plastics are particularly preferred for the purposes of the present invention, since they are outstandingly suitable for the purposes of the present invention in the injection molding process. In the context of the present invention, it is particularly preferred to use a polyolefin, in particular polypropylene, which is optionally filled with fibers. A degree of filling of the plastic in the range from 20 to 40% by weight, based on the total mass of plastic and fibers, is particularly preferred for the purposes of the present invention.

Neben anorganischen Fasern, können erfindungsgemäß auch organische Fasern eingesetzt werden. Besonders bevorzugt im Sinne der vorliegenden Neuerung sind jedoch Glasfasern, da diese dem Kunststoff eine hohe Steifigkeit verleihen.In addition to inorganic fibers, organic fibers can also be used according to the invention. In the context of the present innovation, however, glass fibers are particularly preferred, since they give the plastic a high degree of rigidity.
