Definitions

• the present invention relates to a domestic appliance having a cabinet-shaped housing comprising a plurality of walls, wherein at least one wall of the plurality of walls has an arrangement of embossments.
• the invention relates to a household appliance for the care of laundry, such as a washing machine, a tumble dryer or a washer-dryer.
• Cabinet-shaped household appliances usually have at least one drive motor, which generates oscillations in particular in washing machines during operation in the walls, which are basically made of sheet metal or plastic.
• the generated vibrations bring a number of disadvantages and, among other things, produce unwanted noise.
• the side walls of washing machines were provided with stiffeners.
• WO 2010/066653 A1 discloses a domestic appliance with a multiplicity of walls, of which at least one wall has an arrangement of embossments, the arrangement of embossings having a first embossing centered with respect to a center of the wall and annular in plan view, a second embossing which is arranged outside the first embossing and substantially concentric therewith, annular in plan view, and at least one stripe-shaped third embossing arranged outside the second embossing.
• the object is achieved by a household appliance having a cabinet-shaped housing comprising a multiplicity of walls, wherein at least one wall of the plurality of walls has an arrangement of embossments, and wherein the arrangement of embossings has an embossing which is annular in plan view onto the wall having a center of the annular embossing, and wherein in an inner space of the cabinet-shaped housing an axis of rotation of a drum body is arranged, wherein the center of the annular embossing to the axis of rotation of the
• a drive or a motor is arranged.
• the vibrations generated by the drive within the household appliance can thus be broken down particularly efficiently by the arrangement of at least two mutually parallel embossings, while the
• annular embossing allows an optimal and space-saving arrangement of a drum in the tub.
• the at least two mutually parallel embossing outside of the annular embossing are arranged and formed strip-shaped. In addition, these may also be formed arcuate. This design provides a particularly advantageous and effective damping of the vibrations caused by the drive.
• the arrangement of imprints includes a further annular
• the plurality of walls has a front wall, a rear wall, an upper side and a lower side, and two 5 side walls, wherein at least one of the side walls has the arrangement of embossments.
• the two mutually parallel embossings are arranged below the annular embossing in a direction running from the annular embossing to the underside of the domestic appliance.
• the axis of rotation of the drum body is at the level of an embossed surface embraced by the annular embossing.
• the height of the axis of rotation is at a distance from the center of the annular embossment, wherein the annular embossing has a radius, and the distance is smaller than the radius I 30.
• the radius indicates a distance of the center of the annular embossment to an edge of the annular embossment facing the center. In particular, lies the
• the center of the annular embossment is arranged above a wall center in a direction extending from the wall center to the top of the household appliance direction. This is particularly important in those cases in which the side wall has no overall square but rectangular design. Another advantage is that the axis of rotation or the drum can be arranged in a height above the wall center.
• the domestic appliance has a vibration system that includes the drum body
• the height position of the annular embossing of the side wall or the side walls can be adapted to design features of oscillatory system components.
• oscillatory system components are, for example, a tub or the drum body arranged in the tub.
• the tub may have a weld, and the height position of the annular embossment or the center of the annular embossment is adapted to the height position of the weld.
• a risk of vibration system stops on the sidewall during operation is reduced if maximum deflections of the oscillatory system are at the level of the unembossed region of the sidewall encompassed by the annular embossment.
• a third strip-shaped embossment is arranged, which is arranged outside the annular embossing. 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.
• the third stripe-shaped embossing with respect to the annular b_ £ embossing the at least two mutually parallel embossing I ⁇ arranged opposite.
• the embossments are formed by bulges. These curvatures can be directed in a particularly advantageous manner according to FIG. 5, but they can also be arranged and / or curved in an outward-pointing manner.
• the formation of the embossments in the form of inwardly or outwardly directed curvatures have proven to be particularly stabilizing, the curvatures allow a simple and cost-effective production process of the side walls without sacrificing restrictions 10 in terms of the effectiveness of the damping or the stability of the household appliance altogether to have to.
