Definitions

  • the present invention relates to a housing for a household appliance, in particular the door of a cabinet-like household appliance, such as a refrigerator.
  • the doors of refrigerators tend to deform under external stress, so that the flatness of the door is adversely affected.
  • An essential source of stress is the loading of the appliance door with stored goods in a storage box mounted on the inside of the door. Further stresses result from different temperatures and thermal expansion coefficients of the materials on the inside and outside of the door.
  • Object of the present invention is therefore to provide a household appliance housing that achieves high rigidity in different directions with low material usage.
  • the object is achieved by formed in a household appliance housing with at least one plate-like wall element on the wall element in two different directions elongated stiffening contours.
  • the wall element is a piece of an outer skin of the housing, which is conventionally made of sheet metal and is readily deformable to form the stiffening contour according to the invention.
  • it is a piece of the outer skin of a door of a refrigerator.
  • the stiffening contours are embossed. This makes it easy to keep an edge region of the wall element from the reinforcing contours free, so that it remains substantially rectilinear and in a simple manner tightly and tightly connected to another wall element connectable. In particular, areas where a functional component of the household appliance housing, such as a door hinge to be mounted, kept free of the stiffening contours.
  • the stiffening contours are formed on the visible side raised.
  • Several of the elongated stiffener contours may contact one another, in particular merge, to form together a stiffener extending in various directions.
  • the stiffening contours close to one another an intermediate angle, in particular an acute intermediate angle.
  • the two directions of the stiffening contours extend obliquely over the substantially vertical wall element.
  • one of the two stiffening contours is always highly effective against saddle deformation of the wall element.
  • the wall element has a plurality of identical stiffening elements.
  • the stiffening elements can be produced in the required number on the wall elements. For different device models required wall elements with different dimensions, in particular with different heights, are easily realized by the stiffening elements are formed on the wall elements in each case dependent on their dimensions number.
  • the stiffening elements are preferably unconnected to one another, in particular if each stiffening element is produced in a separate embossing step. In order nevertheless to achieve a substantially uniform flexural rigidity over the entire wall element without weak points, it is preferred that the unconnected stiffening elements overlap one another in the vertical and / or horizontal direction.
  • the outer door of a built-in household appliance in particular a built-in refrigeration device, provided with the stiffening contours, which are raised on the visible side of the outer door.
  • FIG 1 to 4 are each perspective views of refrigerator doors according to various embodiments of the invention.
  • the refrigeration appliance door shown in Fig. 1 in a greatly shortened perspective view comprises in known manner an outer skin formed from sheet metal, from the one piece a front 1, two side walls 2, and not visible in the figure, from the rear edge of the side walls 2 are formed inwardly angled and substantially parallel to the front edge strips 3.
  • a thermoformed plastic inner wall 4 is tightly connected at its lateral edges with the two edge strips 3.
  • On the inner wall vertically elongated, projecting towards the rear spars are formed in a conventional manner, one of which is visible in the figure, and which serve for the suspension of door cabinets.
  • Plastic molded upper and lower end members 5 form each floor and ceiling of a limited by the outer skin and the inner wall 4, filled with insulating cavity.
  • each X-shaped recess 6 In the front 1 are impressed by two embossing steps with a same tool two large, shallow depressions 6 in the form of the letter X.
  • the cross-shaped recesses 6 do not reach the upper and lower edges of the front 1. These therefore run rectilinearly or at most slightly and uniformly curved over their entire width, so that the production of a tight connection for the insulating material between the front 1 and the end elements 5 is not difficult.
  • Doors at different heights for different refrigeration models are made according to the invention by cutting pieces of sheet metal in a length corresponding to the desired height of the door cut from a band, provided with the required number of embossed depressions 6 and bent longitudinally to front 1, side walls 2 and edge strips to build.
  • V-shaped depressions 14 are formed on the front side 1 of the door. Although each of these recesses 14 has the same height as the X-shaped recesses of FIG. 1, they can be accommodated in larger numbers on a door with the same height, as they can be placed vertically overlapping each other.
  • the wells are replaced by embossed into the front 1 projections 15.
  • the projections 15 are like the depressions 6 X-shaped, in contrast to the depressions 6, however, they are not arranged mirror-symmetrically to a center line of the front 1, but slightly twisted against such a symmetrical position.
  • Fig. 4 shows an embodiment in which the front of the door 1 a large number of stiffening contours, here again in the form of recesses 16 and 17 respectively.
  • the individual recesses 16, 17 do not touch each other. They form a pattern having a plurality of horizontal rows and vertical columns, in each of which horizontally elongated depressions 16 and vertically elongate depressions 17 alternate with each other. There is no horizontal or vertical line passing over a central area of the front without crossing several of the recesses 16, 17. So here too the front 1 is effectively stiffened.
  • the pattern of the depressions 16, 17 can be obtained by embossing this line by line, with the embossing tool being displaced sideways between two embossing operations of successive lines.
