Description

DESCRIPTION

Home appliance with patterned wall

The present invention relates to a household appliance with a cabinet-like casing, comprising a plurality of walls, wherein at least one wall of the plurality of walls has an arrangement of stampings. In particular, the invention relates to a household appliance for the treatment of clothes, such as a washing machine, a clothes washer dryer or a clothes dryer.

Household electrical appliances in the form of cabinets generally have at least one drive motor, which generates oscillations, especially in washing machines during operation, on walls that are, in principle, made of sheet metal or plastic. The oscillations generated involve a series of drawbacks and generate, among other things, undesirable noises. To reduce such drawbacks, the side walls of washing machines have been specially provided with reinforcements.

US design patent D 642753 S shows a washing machine.

From the publication WO 2010/066653 A1 a household appliance with a plurality of walls is known, at least one of the walls of which has a stamping arrangement, wherein the stamping arrangement comprises a first ring-shaped stamping in view in the upper plan, arranged centered with respect to the center of the wall, a second stamping, ring-shaped in the top plan view, arranged outside the first stamping and essentially concentric to it, and at least one third stamping in the form of a strip , arranged outside the second stamping. Through the arrangement of a first ring-shaped stamping, a second ring-shaped arrangement arranged concentrically and a third strip-shaped stamping arranged outside of the second stamping, it has indeed been possible to improve the performance of oscillation, but the oscillations of flat wall surfaces nevertheless remain too large.

Therefore, the object of the present invention is to solve the drawbacks of the state of the art and to prepare a domestic appliance in the form of a cabinet, which provides an improved housing.

This task is solved by means of the object with the characteristics according to the independent claim. Advantageous embodiments of the invention are the subject of the figures, the description and the dependent claims.

According to one aspect of the invention, the problem is solved by means of a household appliance with a cabinet-like casing, comprising a plurality of walls, wherein the plurality of walls comprises a front wall, a rear wall, a upper side and a lower side as well as two side walls, wherein at least one of the side walls has an arrangement of stampings, and wherein the arrangement of stamps comprises a ring-shaped stamping in a top plan view on the wall with a midpoint of the ring-shaped stamping, wherein the midpoint of the ring-shaped stamping is arranged above a center of the wall in a direction extending from the center of the wall to the upper side of the household appliance. In this way, for example, the technical advantage can be realized that the arrangement of stampings both effectively reduces the oscillations of the housing device in operation and also takes account of aesthetic points of view. . This is especially important in cases where the side wall does not generally have a square configuration, but rather a rectangular one.

According to the invention, the cabinet-shaped housing delimits an interior space of the household appliance. In this interior space of the cabinet-like housing, an axis of rotation of a drum body is arranged according to the invention, wherein the axis of rotation is located according to the invention at a height of a non-stamped surface comprised by a ring-shaped stamping. In this way, the axis of rotation can be arranged above the center of the wall. The oscillations of the household appliance are essentially generated by the rotation of the drum body or by a drive of the drum body. In this way, by adapting the ring-shaped stamping to the position of the height of the axis of rotation, the propagation of the oscillation on the side wall can be minimized. If the household appliance has an oscillation system, which comprises the drum body, then the risk of impacts of the oscillation system during operation is further reduced, when there are maximum deviations of the oscillation system in the non-stamped area of the side wall comprised of ring-shaped stamping. in the same way, a possible risk of transport damage is counteracted.

Furthermore, according to the invention, the axis of rotation is at the height of the midpoint of the ring-shaped stamping. This is advantageous when there are maximum deviations of the oscillation system at the height of the axis of rotation.

Alternatively, the axis of rotation has a distance from the midpoint of the ring stamp, where the ring stamp has a radius, and the distance is less than the radius. The radius indicates a distance of the midpoint of the ring-shaped stamp from an edge of the ring-shaped stamp directed towards the midpoint. According to the invention, the axis of rotation is, in the alternative, at a height below the midpoint of the ring-shaped stamping. In this way, for example, the technical advantage is achieved that an improvement in stiffness or in modal behavior is possible through offset stampings. This reduces the risk of impacts to the oscillation system during operation as well as the risk of possible transport damage to the appliance.

In particular, the position of the height of the ring-shaped stamping can be adapted to the constructional peculiarities of components of the oscillation system. Such components of the oscillation system are, for example, a bleach tank or the drum body arranged in the bleach tank. In particular, the bleach tank can have a weld seam, and the position of the height of the ring-shaped stamping or the midpoint of the ring-shaped stamping can be adapted to the position of the height of the ring-shaped stamping. welding seam.

In order to make best use of the available surface area of a side wall of the household appliance, which is generally rectangular in shape, the at least two stamped parallel to one another are arranged outside of the ring-shaped stamper and are configured in strip shape. If the household appliance is a washing machine, a washing machine dryer or a clothes dryer, then a drive or a motor is usually arranged in a lower region of the cabinet-like housing. The oscillations generated by the drive within the household appliance can be dissipated in a particularly efficient way through the arrangement of at least two stampings arranged parallel to each other, while the ring-shaped stamping enables an optimal and space-saving arrangement of a drum in the cabinet-like housing.

Furthermore, the two stampings arranged parallel to one another can also be designed in the shape of an arc. This configuration offers a particularly advantageous and effective damping of oscillations caused by the drive.

Since, in particular in the case of washing machines, at least one motor or one drive is located in the lower region of the household appliance, the two stamped stamped parallel to each other are arranged under the ring-shaped stamper in a direction that is extends from the ring-shaped stamping to the underside of the household appliance. In this case, the occurrence of oscillations caused by the drive can be effectively absorbed in the lower region of the household appliance, so that the stampings arranged parallel to each other are immediately arranged at the height of the drive generating the oscillations.

In order to make best use of the available surface of the generally rectangular wall, a third strip-shaped embossment is configured in the stamping arrangement, which is arranged outside the ring-shaped stamping. This further improves the damping behavior of the side wall or further increases the rigidity and modal behavior of the household appliance in general. It is especially effective to carry out the third stamping arranged in the form of strips in an arc-shaped configuration. Alternatively, however, it would also be possible to configure the third strip-shaped embossment in a linear, rectangular, sickle-shaped or any other conceivable way.

In order to enable a particularly effective utilization of the surface in the case of rectangular-shaped side surfaces and thus a particularly effective damping property of the side wall, the third stamping arranged in the form of strips is arranged, relative to the stamping. in the form of a ring, opposite to the at least two stamps arranged parallel to each other.

To control or reduce the oscillation behavior of household appliances, especially washing machines with fast rotations and fast spin processes, the stamping arrangement comprises another ring-shaped stamping, which is arranged concentrically to the ring-shaped stamping. Both the first ring-shaped stamping and the other ring-shaped stamping can be both circular, circular and orally shaped.

According to a particularly preferred embodiment, the embossments are designed with arcuate curvatures. These arcuate curvatures may be directed in a particularly preferred way inward, but may be arranged or directed in the same way arcuately outward. The configuration of the stampings in the form of arcuate curvatures directed inwards or outwards have given good results especially with a stabilizing effect, where the arcuate curvatures allow a simple and economical manufacturing process of the side walls without having to tolerate in this case , in general, limitations regarding the effectiveness of the damping or stability of the appliance.
