Definitions

  • the invention relates to a household appliance, in particular a water-conducting household appliance. Specifically, the invention relates to the field of laundry treating appliances used for washing and / or drying laundry.
  • a household appliance with a cabinet-shaped housing is known.
  • the cabinet-shaped housing includes a plurality of walls, at least one of which has an array of embossments.
  • the arrangement of embossments comprises a first embossing, which is centered with respect to a center of the wall and annular in plan view, a second embossment which is concentric with the first embossment, annular in plan view, and a third embossing arranged outside the second embossment.
  • the structuring of sheets by embossing in each case in the deformation zones force a node, whereby the still possible vibration modes of the sheet metal component are limited to some basic forms.
  • "tiling” means a structure mounted in or on a surface consisting of a wide variety of individual surface elements, each of which has dimensions of a maximum length substantially less than each maximum diameter of the surface.
  • tiling are floor coverings made of wooden or ceramic surface elements, each having dimensions that are significantly smaller than the dimensions of the floor under consideration
  • a floor which is formed from planks or boards, which extend from one side of the living space to the other side.
  • Also described in the aforementioned WO 2010/066653 A1 structure of a wall of a household appliance is no tiling.
  • U.S. Patent 4,133,152 to inventor Roger Penrose describes a closed, non-periodic tiling of a surface by a plurality of elements referred to as "tiles.”
  • the surface may be a floor or wall of a building or an instructive play of a kind
  • Such non-periodic tilings are now commonly referred to as "Penrose tilings”.
  • WO 2001/085274 A1 also discloses such tilings.
  • the object of the invention is to provide a household appliance, which has a further improved structure. Specifically, it is an object of the invention to provide a household appliance in which noise emissions are reduced. The object is achieved by a household appliance according to the independent claim.
  • a household appliance which may be configured in particular as a water-conducting household appliance, wherein a housing is provided and the housing has at least one housing wall with an embossing pattern, and wherein the embossing pattern is based on a Penrose tiling.
  • the embossing pattern based on the Penrose tiling does not permit symmetries from the outset.
  • the embossing pattern is not only selective with respect to possible modes of vibration, but overall vibration suppressing. This means that the embossing pattern does not specify any natural oscillations that would lead to preferred frequency ranges for oscillations during operation. This applies to natural oscillations with wavelengths that are on the order of fractions of the plate dimensions. Significant here are fractions that result from small integer ratios, such as 1/2 or 2/3.
  • the Penrose tiling is composed of a variety of tiles.
  • the embossing pattern comprises area pieces which are each configured within a tile of the Penrose tiling.
  • the surface pieces are formed as flat surface pieces. This simplifies the production.
  • a surface piece in turn constitutes a membrane surface, on which in turn oscillation patterns of certain oscillation modes now result on a smaller scale.
  • a structural constant of the embossing pattern can be set correspondingly small, so that such oscillations have a negligible influence on the acoustic emission with respect to their frequency and amplitude.
  • a significant reduction of the acoustic emissions can thus be achieved.
  • the embodiment of the embossing pattern can be cost-effective with respect to the effect achieved. Specifically, a significantly improved damping of vibration modes can thus be achieved with a comparable production outlay.
  • the embossing pattern has webs which extend in each case along joined edges of tiles of the Penrose tiling.
  • the surface pieces between the webs may be configured as depressions in the housing wall. Due to a certain web width, in this case, a width of the area pieces decreases with respect to a given tile size of the tiles.
  • the webs to some extent form a continuous, flat surface, while the surface pieces are separated from each other by the webs.
  • the smaller web width of the webs avoids vibration patterns in this regard.
  • the webs of the embossing pattern are formed here in an advantageous manner between the surface pieces of the embossing pattern.
  • the number of tiles composing the Penrose tiling is selected from a range of 10 to 100 , It is particularly advantageous that the number of tiles is selected from a range of 20 to 80. Further advantageous is a selection from a range of 30 to 50 tiles. Specifically, the number of tiles composing the Penrose tiling may be about 40.
  • the Penrose tiling consists of preferably two different tile types, whose shape and ranking scheme is subject to the rules of Penrose tiling, to allow overall quasi-periodicity. This results in a non-periodic tile pattern with which a plane (shown as infinitely expanded) can be parquetted without gaps, without a basic scheme repeating itself periodically. In the practical embodiment of this tile pattern is limited to the dimensions of the housing wall. For reasons of manufacturability and mountability, the embossing pattern for the housing wall can also provide a peripheral edge. In addition, suitable formations may be provided at certain points of the embossing pattern, which are required, for example, for reasons of attachment or assembly.
  • the Penrose tiling allows different variations of shapes, which can be used, for example, for design reasons. It is also conceivable, by an adapted shape of the elements of the embossed pattern, in particular the patches and the webs, in addition to reduce the remaining natural oscillations of these elements (structural elements). Optionally, one or more of the formation rules may be violated in places, for example, for manufacturing reasons or to meet a predetermined component symmetry.
  • the housing wall can be composed of two partial sheets. Preferably, however, the housing wall is made in one piece, in particular from a metal sheet.
  • the Penrose tiling is composed of a first tile and a second tile type, that the first tile is based on a rhombus with corner angles of 36 ° and 144 ° and that the second tile on a rhombus with corner angles of 72 ° and 108 ° based.
  • This embodiment allows on the one hand a shapely embossing pattern and on the other hand an effective vibration damping.
  • housing walls is possible, which are visible to the user.
  • the housing is designed as a cabinet-shaped housing and that a first side wall and a second side wall of the housing each have an embossing pattern based on a Penrose tiling.
  • a front of the case may also have an embossed pattern based on a Penrose tiling.
  • Further side walls of the housing may each have an embossing pattern based on a Penrose tiling.
  • the embossing pattern of a housing wall is based on a Penrose tiling with more than two types of tile.
