Description

Die vorliegende Erfindung betrifft ein Haushaltsgerät mit einem schrankförmigen Gehäuse umfassend eine Vielzahl von Wänden, wobei mindestens eine Wand der Vielzahl von Wänden eine Anordnung von Prägungen aufweist. Insbesondere betrifft die Erfindung ein Haushaltsgerät zur Pflege von Wäsche, wie einer Waschmaschine, einem Wäschetrockner oder einem Waschtrockner.The present invention relates to a household appliance with a cabinet-shaped housing comprising a plurality of walls, at least one wall of the plurality of walls having an arrangement of embossings. In particular, the invention relates to a household appliance for caring for laundry, such as a washing machine, a tumble dryer or a washer-dryer.

Schrankförmige Haushaltsgeräte weisen meist zumindest einen Antriebsmotor auf, welcher insbesondere bei Waschmaschinen während des Betriebs in den grundsätzlich aus Metallblech oder Kunststoff ausgebildeten Wänden Schwingungen erzeugt. Die erzeugten Schwingungen bringen eine Reihe von Nachteilen mit sich und erzeugen, unter anderem, unerwünschte Geräusche. Um derartige Nachteile zu reduzieren, wurden insbesondere die Seitenwände von Waschmaschinen mit Versteifungen versehen.Cabinet-shaped household appliances mostly have at least one drive motor which, in particular in washing machines, generates vibrations in the walls, which are basically made of sheet metal or plastic, during operation. The vibrations generated have a number of disadvantages and, among other things, generate undesirable noises. In order to reduce such disadvantages, the side walls of washing machines in particular were provided with stiffeners.

Das Designpatent US D 642 753 S zeigt eine Waschmaschine.The design patent US D 642 753 p shows a washing machine.

Aus der Druckschrift WO 2010/066653 A1 ist ein Hausgerät mit einer Vielzahl von Wänden bekannt, von denen mindestens eine Wand eine Anordnung von Prägungen aufweist, wobei die Anordnung von Prägungen eine bezüglich eines Zentrums der Wand zentriert angeordnete, in der Draufsicht ringförmige erste Prägung, eine außerhalb der ersten Prägung und im Wesentlichen konzentrisch zur dieser angeordnete, in der Draufsicht ringförmige zweite Prägung und zumindest eine außerhalb der zweiten Prägung angeordnete, streifenförmige dritte Prägung umfasst. Durch die Anordnung einer ersten ringförmigen Prägung, einer konzentrisch angeordneten zweite ringförmige Prägung und einer außerhalb der zweiten Prägung angeordnete streifenförmige dritte Prägung, konnte zwar das Schwingungsverhalten verbessert werden, jedoch blieben die Schwingungen flacher Flächen der Wände dennoch zu groß.From the pamphlet WO 2010/066653 A1 A household appliance with a plurality of walls is known, of which at least one wall has an arrangement of embossments, the arrangement of embossments being a first embossing which is arranged centered with respect to a center of the wall and which is ring-shaped in plan view, one outside the first embossing and essentially comprises a second embossing arranged concentrically to the latter and ring-shaped in plan view and at least one strip-shaped third embossing arranged outside the second embossing. By arranging a first ring-shaped embossing, a concentrically arranged second ring-shaped embossing and a strip-shaped third embossing arranged outside the second embossing, the vibration behavior could be improved, but the vibrations of flat surfaces of the walls remained too great.

Es ist daher die Aufgabe der vorliegenden Erfindung die Nachteile aus dem Stand der Technik zu überwinden und ein schrankförmiges Haushaltsgerät bereitzustellen, welches ein verbessertes Gehäuse vorsieht.It is therefore the object of the present invention to overcome the disadvantages of the prior art and to provide a cabinet-shaped household appliance which provides an improved housing.

Diese Aufgabe wird durch den Gegenstand mit den Merkmalen nach dem unabhängigen Anspruch gelöst. Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Figuren, der Beschreibung und der abhängigen Ansprüche.This object is achieved by the subject matter with the features according to the independent claim. Advantageous embodiments of the invention are the subject matter of the figures, the description and the dependent claims.

Gemäß einem Aspekt der Erfindung wird die Aufgabe durch ein Haushaltsgerät mit einem schrankförmigen Gehäuse umfassend eine Vielzahl von Wänden, wobei die Vielzahl von Wänden eine Vorderwand, eine Rückwand, eine Oberseite und eine Unterseite, sowie zwei Seitenwände umfasst, wobei zumindest eine der Seitenwände eine Anordnung von Prägungen aufweist, und wobei die Anordnung von Prägungen eine in einer Draufsicht auf die Wand ringförmige Prägung mit einem Mittelpunkt der ringförmigen Prägung umfasst, wobei der Mittelpunkt der ringförmigen Prägung oberhalb eines Wandzentrums in einer von dem Wandzentrum zur Oberseite des Haushaltsgeräts verlaufenden Richtung angeordnet ist. Dadurch kann beispielsweise der technische Vorteil realisiert werden dass durch die Anordnung von Prägungen sowohl Schwingungen des Haushaltsgeräts im Betrieb effektiv reduziert werden, als auch ästhetischen Gesichtspunkten Rechnung getragen werden. Dies ist insbesondere in den Fällen von Bedeutung, in denen die Seitenwand keine insgesamt quadratische sondern rechteckige Ausbildung aufweist.According to one aspect of the invention, the object is achieved by a domestic appliance with a cabinet-shaped housing comprising a plurality of walls, the plurality of walls comprising a front wall, a rear wall, a top and a bottom, and two side walls, at least one of the side walls being an arrangement of embossments, and wherein the arrangement of embossments comprises an embossing ring-shaped in a plan view of the wall with a center point of the ring-shaped embossing, the center point of the ring-shaped embossing being arranged above a wall center in a direction running from the wall center to the top of the household appliance. In this way, for example, the technical advantage can be realized that the arrangement of embossings effectively reduces vibrations of the household appliance during operation and also takes aesthetic aspects into account. This is particularly important in those cases in which the side wall does not have an overall square but rectangular configuration.

Das schrankförmigen Gehäuse begrenzt erfindungsgemäß einen Innenraum des Haushaltsgerätes. In diesem Innenraum des schrankförmigen Gehäuses ist erfindungsgemäß eine Rotationsachse eines Trommelkörpers angeordnet, wobei die Rotationsachse erfindungsgemäß auf einer Höhe einer von der ringförmigen Prägung umfassten ungeprägten Fläche liegt. Auf diese Weise kann die Rotationsachse oberhalb des Wandzentrums angeordnet werden. Die Schwingungen des Haushaltsgerätes werden wesentlich durch Rotation des Trommelkörpers bzw. durch einen Antrieb des Trommelkörpers erzeugt. Somit kann durch Anpassung der ringförmigen Prägung an die Höhenposition der Rotationsachse die Schwingungsausbreitung in der Seitenwand minimiert werden. Weist das Haushaltsgerät ein Schwingsystem auf, das den Trommelkörper umfasst, so ist darüber hinaus ein Risiko von Schwingsystemanschlägen während des Betriebs reduziert, wenn maximale Ausschläge des Schwingsystems in dem von der ringförmigen Prägung umfassten ungeprägten Bereich der Seitenwand liegen. Ebenso wird einem möglichen Risiko von Transportschäden entgegengewirkt.According to the invention, the cabinet-shaped housing delimits an interior space of the household appliance. According to the invention, an axis of rotation of a drum body is arranged in this interior space of the cabinet-shaped housing, the axis of rotation according to the invention being at the level of an unembossed surface enclosed by the annular embossing. In this way, the axis of rotation can be arranged above the center of the wall. The vibrations of the household appliance are essentially generated by the rotation of the drum body or by a drive of the drum body. Thus, by adapting the ring-shaped embossing to the height position of the axis of rotation, the propagation of vibrations in the side wall can be minimized. If the household appliance has an oscillating system that includes the drum body, the risk of oscillating system stops during operation is also reduced if maximum deflections of the oscillating system are in the unembossed area of the side wall encompassed by the annular embossing. Likewise, a possible risk of transport damage is counteracted.

Weiter liegt erfindungsgemäß die Rotationsachse auf Höhe des Mittelpunktes der ringförmigen Prägung. Dies ist vorteilhaft, wenn maximale Ausschläge des Schwingsystems auf Höhe der Rotationsachse liegen.Furthermore, according to the invention, the axis of rotation lies at the level of the center of the ring-shaped embossing. This is advantageous when the maximum deflections of the oscillating system are at the level of the axis of rotation.

Alternativ weist die Rotationsachse erfindungsgemäß einen Abstand zu dem Mittelpunkt der ringförmigen Prägung auf, wobei die ringförmige Prägung einen Radius aufweist, und der Abstand kleiner als der Radius ist. Der Radius gibt einen Abstand des Mittelpunktes der ringförmigen Prägung zu einem dem Mittelpunkt zugewandten Rand der ringförmigen Prägung an. Erfindungsgemäß liegt die Rotationsachse bei der Alternative auf einer Höhe unterhalb des Mittelpunktes der ringförmigen Prägung. Dadurch wird beispielsweise der technische Vorteil erreicht, dass eine zusätzliche Verbesserung der Steifigkeit beziehungsweise des Modalverhaltens durch die versetzen Prägungen möglich ist. Dies reduziert das Risiko von Schwingsystemanschlägen während des Betriebs sowie das Risiko möglicher Transportschäden des Haushaltsgeräts.Alternatively, according to the invention, the axis of rotation is at a distance from the center point of the annular embossing, the annular embossing having a radius and the distance being smaller than the radius. The radius specifies a distance between the center of the annular embossing and an edge of the annular embossing facing the center. According to the invention, the axis of rotation in the alternative is at a level below the center point of the annular embossing. As a result, for example, the technical advantage is achieved that an additional improvement in the stiffness or the modal behavior is possible through the offset embossing. This reduces the risk of vibration system attacks during operation and the risk of possible transport damage to the household appliance.

Insbesondere kann die Höhenposition der ringförmigen Prägung an konstruktive Besonderheiten von Schwingsystemkomponenten angepasst werden. Derartige Schwingsystemkomponenten sind beispielsweise ein Laugenbehälter bzw. der im Laugenbehälter angeordnete Trommelkörper. Insbesondere kann der Laugenbehälter eine Schweißnaht aufweisen, und die Höhenposition der ringförmigen Prägung bzw. des Mittelpunktes der ringförmigen Prägung kann an die Höhenposition der Schweißnaht angepasst sein.In particular, the height position of the ring-shaped embossing can be adapted to special design features of oscillating system components. Such vibration system components are, for example, a tub or the drum body arranged in the tub. In particular, the tub can have a weld seam, and the height position of the annular embossing or the center of the annular embossing can be adapted to the height position of the weld seam.

Um die zur Verfügung stehende Fläche einer Seitenwand des Haushaltsgeräts, welche in der Regel rechteckig ausgebildet ist, möglichst gut auszunutzen, sind die zumindest zwei zueinander parallel angeordnete Prägungen außerhalb der ringförmigen Prägung angeordnet und streifenförmig ausgebildet. Handelt es sich bei dem Haushaltsgerät um eine Waschmaschine, einen Wäschetrockner oder einen Waschtrockner, so ist üblicherweise in einem unteren Bereich des schrankförmigen Gehäuses ein Antrieb beziehungsweise ein Motor angeordnet. Die durch den Antrieb erzeugten Schwingungen innerhalb des Haushaltsgeräts können somit durch die Anordnung von zumindest zwei zueinander parallel angeordneten Prägungen besonders effizient abgebaut werden, während die ringförmige Prägung eine optimale und platzsparende Anordnung einer Trommel in dem schrankförmigen Gehäuse ermöglicht.In order to utilize the available area of a side wall of the household appliance, which is generally rectangular, as well as possible, the at least two mutually parallel embossings are arranged outside the annular embossing and are designed in strips. If the household appliance is a washing machine, a tumble dryer or a washer dryer, a drive or a motor is usually arranged in a lower region of the cabinet-shaped housing. The vibrations generated by the drive within the household appliance can thus be reduced particularly efficiently by the arrangement of at least two mutually parallel embossings, while the annular embossing enables an optimal and space-saving arrangement of a drum in the cabinet-shaped housing.

Zudem können die zwei zueinander parallel angeordneten Prägungen auch bogenförmig ausgebildet sein. Diese Ausbildung bietet eine besonders vorteilhafte und effektive Dämpfung der durch den Antrieb verursachten Schwingungen.In addition, the two embossings arranged parallel to one another can also be formed in an arc shape. This design offers a particularly advantageous and effective damping of the vibrations caused by the drive.

Da sich insbesondere im Falle von Waschmaschinen zumindest ein Motor, beziehungsweise ein Antrieb, in dem unteren Bereich des Haushaltsgeräts befindet, sind die zwei zueinander parallel angeordneten Prägungen unterhalb der ringförmigen Prägung in einer von der ringförmigen Prägung zur Unterseite des Haushaltsgeräts verlaufenden Richtung angeordnet. Hierbei kann der Entstehung von Schwingungen, verursacht durch den Antrieb, im unteren Bereich des Haushaltsgeräts effektiv Rechnung getragen werden, indem die zueinander parallel angeordneten Prägungen unmittelbar auf Höhe des die Schwingungen erzeugenden Antriebs angeordnet sind.Since at least one motor or drive is located in the lower area of the household appliance, especially in the case of washing machines, the two embossings arranged parallel to one another are arranged below the annular embossing in a direction running from the annular embossing to the underside of the household appliance. In this case, the generation of vibrations caused by the drive in the lower area of the household appliance can be effectively taken into account, in that the embossings arranged parallel to one another are arranged directly at the level of the drive generating the vibrations.

Um die zur Verfügung stehende Fläche der in der Regel rechteckigen Wand möglichst gut zu nutzen, ist bei der Anordnung von Prägungen eine dritte streifenförmig angeordnete Prägung ausgebildet, welche außerhalb der ringförmigen Prägung angeordnet ist. Dies verbessert zudem das Dämpfungsverhalten der Seitenwand beziehungsweise erhöht zusätzlich die Steifigkeit und das Modalverhalten des Haushaltsgeräts insgesamt. Besonders effektiv ist es, die dritte streifenförmige angeordnete Prägung in einer bogenförmigen Ausbildung zu realisieren. Alternativ wäre es jedoch ebenso denkbar, die dritte streifenförmig angeordnete Prägung geradlinig rechteckig sichelförmig oder auf jede sonstige denkbare Weise auszubilden.In order to make the best possible use of the available area of the generally rectangular wall, a third embossing, which is arranged in the form of a strip and is arranged outside the annular embossing, is formed when the embossings are arranged. This also improves the damping behavior of the side wall or additionally increases the rigidity and the modal behavior of the household appliance as a whole. It is particularly effective to realize the third, strip-shaped embossing in an arc-shaped configuration. Alternatively, however, it would also be conceivable to design the third embossing, which is arranged in the form of a strip, to be rectilinear, rectangular, sickle-shaped or in any other conceivable way.

Um insbesondere bei rechteckig ausgebildeten Seitenflächen eine besonders effektive Flächennutzung und somit besonders effektive Dämpfungseigenschaft der Seitenwand zu ermöglichen, ist die dritte streifenförmig angeordnete Prägung, bezüglich der ringförmigen Prägung den zumindest zwei zueinander parallel angeordneten Prägung gegenüberliegend angeordnet.In order to enable particularly effective use of space and thus particularly effective damping properties of the side wall, particularly with rectangular side surfaces, the third embossing, which is arranged in strip form, is arranged opposite the at least two mutually parallel embossing with respect to the annular embossing.

Um das Schwingungsverhalten von Haushaltsgeräten insbesondere von Waschmaschinen mit schnellen Rotationen und schnellen Schleudergängen zu kontrollieren beziehungsweise effektiv zu reduzieren, umfasst die Anordnung von Prägungen eine weitere ringförmige Prägung, die konzentrisch zu der ringförmigen Prägung angeordnet ist. Sowohl die erste ringförmige Prägung als auch die weitere ringförmige Prägung können sowohl kreisrund als auch oval ausgebildet sein.In order to control or effectively reduce the vibration behavior of household appliances, in particular of washing machines with fast rotations and fast spinning cycles, the arrangement of embossings includes a further annular embossing which is arranged concentrically to the annular embossing. Both the first ring-shaped embossing and the other ring-shaped embossing can be both circular and oval.

Gemäß einer besonders bevorzugten Ausführungsform sind die Prägungen durch Wölbungen ausgebildet. Diese Wölbungen können in besonders vorteilhafter Weise nach innen gerichtet sein, jedoch können Sie ebenso nach außen gerichtet gewölbt angeordnet beziehungsweise ausgebildet sein. Die Ausbildung der Prägungen in Form von nach innen oder nach außen gerichteten Wölbungen haben sich als besonders stabilisierend erwiesen, wobei die Wölbungen einen einfachen und kostengünstigen Herstellungsprozess der Seitenwände ermöglichen ohne dabei Einschränkungen hinsichtlich der Effektivität der Dämpfung oder der Stabilität des Haushaltsgeräts insgesamt in Kauf nehmen zu müssen.According to a particularly preferred embodiment, the embossments are formed by arches. These curvatures can be directed inward in a particularly advantageous manner, but they can also be arranged or formed curved outwardly. The formation of the embossments in the form of inwardly or outwardly directed curvatures have proven to be particularly stabilizing, the curvatures allowing a simple and inexpensive manufacturing process for the side walls without any restrictions with regard to the effectiveness of the damping or the stability of the household appliance as a whole have to.

The household appliance 100 with the cabinet-shaped housing 101 comprises a front wall 103, a rear wall 108, an upper side 109 and a lower side 107 and two side walls 105, 106. The arrangement of embossments 113, 117, 119, 120, 121 and 123 is arranged on the side wall 105. The embossing 117 is annular, the further annular embossing 120 being arranged concentrically to the annular embossing 117. Two embossings 121 and 123 arranged parallel to one another are arranged in a lower region of the side wall 105, these being arranged outside the annular embossing 117 and outside the further annular embossing 120 arranged concentrically to the annular embossing 117. The at least two mutually parallel embossings 121 and 123 are strip-shaped and arcuate and are located below both the annular embossing 117 and the further annular embossing 120 in a direction running from the annular embossing 117 to the bottom 107 of the household appliance 100. The arcuate embossings 121 and 123 could alternatively also be referred to as banana-shaped. Above the ring-shaped embossing 117 and the further ring-shaped embossing 120, a third embossing 119 arranged in a strip-like manner is arranged, the third embossing 119 arranged in a strip-like manner also being arcuate. The third embossing 119 arranged in strip form is arranged on the side wall 105 with respect to the annular embossing 117 opposite the at least two mutually parallel embossings 121 and 123 and is thus located between the annular embossing 117 and a connecting section between the side wall 105 and the top 109.
