Definitions

  • the present invention relates to a household refrigerating appliance, comprising a body with an inner container defining at least one refrigerated space and a door opening and closing the refrigerator compartment having an inner wall, an outer wall and insulating material disposed therebetween, the door panel having at least one vertically oriented stiffening rail.
  • a domestic refrigeration appliance having an inner wall and vertically extending spar sections, as well as vertically oriented stiffening rails is in the DE 10 2005 021 537 A1 described.
  • the spars are at least partially formed by a vertical profile part and the latching steps on the profile part educated.
  • the manner in which the inner wall of the door is made by deep-drawing entails that the wall thickness of the spars, in which the plastic material is more extensively stretched than in the surrounding, substantially flat areas of the inner wall of the door, is thinner than these adjacent areas, and the protrusions formed from the flanks of the spars are in turn thinner than the rest of the spar. It is therefore a considerable thickness of the inner wall required to ensure sufficient load capacity of the door rests bearing projections. With door cabinets projecting far beyond the spars, not only the weight of the door racks and the objects located thereon act on the projections, but also leverage forces can be exerted on the protrusions.
  • the object of the invention is to provide a household refrigerator, which has an improved rigidity.
  • a household refrigerator comprising a body with an inner container which defines at least one refrigerator and a refrigerator door opening and closing door leaf with an inner wall, an outer wall and interposed insulating material, wherein the door leaf has at least one vertically oriented stiffening rail, and the at least one stiffening rail is inserted in a bent side edge portion of the outer wall or the inner wall.
  • the one or more stiffening rails can be inserted or clamped in the corner regions, in particular on the left and right edges of the door leaf. If stiffening of the door leaf is not to take place directly, but stiffening of the domestic refrigerator generally, the stiffening rails according to the invention can also be used in connection areas or bent lateral edge or corner sections of the body of the domestic refrigerator.
  • the at least one stiffening rail is inserted in a bent lateral edge portion of the outer wall or the inner wall, in particular an undesirable warping of the outer wall or the inner wall can be prevented or significantly reduced.

  • stiffening rails By inserting stiffening rails in bent lateral edge portions of the outer wall or the inner wall, the door leaf and in particular the outer wall of the door panel can be stretched, so that the plane of the door leaf or the outer wall is stretched in the area and thus unwanted curvatures pulled smoothly or be prevented from the outset because of the inherent clamping forces and expansion forces.
  • the at least one stiffening rail is fixed in a connecting region of the inner wall and outer wall and in particular firmly connected to a Umbug of the door leaf, the rigidity of the household refrigerator is improved.

With the positioning according to the invention, the door leaf or the domestic refrigerator acquires a higher inherent rigidity.
  • stiffening rails and insulating foam can be saved, which in the absence of the stiffening rails Room at the lateral edge portions of the outer wall or inner wall would have to fill.
  • the stiffening rails are also arranged in particular in such connection areas of inner wall and outer wall, which lie outside the contour of a door leaf seal and thus are outside of an area requiring insulation of the door leaf.

  • the distance between the free ends of the two legs is slightly smaller than the width of the stiffening rail to be used.
  • the legs when inserting the stiffening rail in the U-shaped curved edge portion, the legs are elastically bent and in the inserted position of the stiffening rail, the two legs exert a clamping force on the stiffening rail due to the internal spring tension.
  • the stiffening rail is held in the U-shaped bent edge portion.

  • the stiffening rail thus lies against the entire surface touching the inside of the edge portion.
  • the stiffening rail may in particular have a rectangular or square cross-sectional contour. Since only the outwardly facing side of the stiffening rail is decisive, the stiffening rail can, for example, also have a C-shaped, H-shaped, T-shaped or double-L-shaped cross-sectional shape. To form a rounded door leaf sidewall can However, the stiffening rail also have a cross-sectional contour with a circular section-shaped portion.

In other words, the outer wall or inner wall is fixed over the entire length of the stiffening rail. Thus, selectively or only partially occurring forces can be completely introduced into the door leaf and evenly distributed therein. This makes the inner state of stress even, so that a smooth or shape-stable outer wall or inner wall can be obtained, which does not deform when the temperature changes or an otherwise expected deformation is significantly reduced.

The majority of hardwood species are actually physically harder than the non-generic softwoods. Hardwood is thus generally also used to refer to hardwood in the botanical sense, but in the context of the invention it is still referred to as hardwood when wood having a greater physical hardness is meant. The greater hardness of hardwood is due to a large proportion of fibers and its tight vessel structure, which is due to a slow growth of the tree. Hardwood can be physically distinguished from softwood by its density of earth. Dirt density is the raw density of dry wood at zero percent wood moisture. Wood with a density of 0.55 g / cm 3 or 550 kg / m 3 is referred to in professional circles as hardwood. The most important representatives of hardwoods are, for example, beech, oak, ash, birch and linden.
