    SIDE WALL FOR A FRAME OF A DOMESTIC APPLIANCE, FRAME, AND DOMESTIC APPLIANCE
    DESCRIPTION
    The invention refers to a side wall for a frame of a household appliance for the treatment of garments. The side wall has a flange section that extends in the side wall mounting position towards an opposite side wall of the frame. The flange section comprises means for fixing a spring element configured to hold a vat of the domestic appliance. In addition, the invention refers to a frame for a household appliance with such a side wall, and a household appliance with such a frame.
    In household appliances such as washing machines or washer-dryers, an oscillating system is suspended inside the frame. Such an oscillating system comprises a water tank containing the detergent in the case of a washing machine, and a drum that rotates inside the tank during operation of the domestic appliance. Normally, the oscillating system hangs from the frame with at least two springs. Here, a first spring is fixed to a flange section of a first side wall of the frame. A second spring is fixed to the flange section of the opposite side wall. These flange sections are also called frame wings, and protrude from an upper end of each side wall towards the opposite side wall.
    In household appliances according to the prior art, the springs are fixed directly to the frame wings. An intermediate part of plastic or lubricant can be provided to prevent friction between the springs and the frame wings.
    However, in particular if the oscillating system hangs only at these two points, the weight of the oscillating system can cause deformation in the flange or frame wing section. This deformation of the frame wing can also cause deformation of the side wall or side side of the frame in a static situation, that is, when the oscillating system does not move. In a dynamic situation, in which the oscillating system moves during operation of the domestic appliance, such deformation of the side wall can cause annoying vibrations. Likewise, deformation of the lateral side or side wall of the frame can cause an aesthetic defect that is visible to the user of the domestic appliance in those cases in which the appliance is not incorporated into a piece of furniture.

    In a case where the domestic appliance is incorporated or inserted into a lower part, the deformation of the side wall may be responsible for noises of greater intensity. Such noises can originate from resonance frequencies that are due to possible collisions of the side wall of the frame with a wall of the furniture in which the domestic appliance is incorporated.
    From the prior art, the resolution of these problems by reinforcing the frame wings is known. This can be done, for example, by increasing the thickness of the rolled metal that forms the flange section and the side wall. Alternatively, it is possible to add a bar or strut that extends from the frame wing of the first side wall to the frame wing of the second side wall. Such transverse strut covers access to the oscillating system. In addition, these approaches are quite expensive and increase the weight of the household appliance.
    Also, these approaches do not solve the root problem. The cause of the problem is that the stresses linked to the weight of the oscillating system are concentrated at one point, that is, at the point where the spring hangs from the flange or frame wing section. Accordingly, approaches in accordance with the prior art reduce deformation of the frame wing, but undesirable deformation remains present.
    Therefore, the present invention solves the technical problem of providing a side wall of the type mentioned at the beginning, which makes it possible to minimize deformation of the side wall in a simple and economical manner, as well as providing a corresponding frame and a domestic appliance correspondent.
    This technical problem is solved by a side wall, by a frame, and by a domestic appliance with the characteristics of the respective independent claims. In the dependent claims, advantageous configurations are specified with other convenient developments of the invention.
    The side wall according to the invention for a frame of a domestic appliance for the treatment of garments has a flange section. In the side wall mounting position, that is, when the side wall is part of the frame of the domestic appliance, this flange section extends to an opposite side wall of the frame. The flange section comprises means for attaching a spring element to the flange section. The spring element is configured to hold a vat of the domestic appliance. The means to fix the spring element

    they comprise an opening or a recess in the flange section and a strut that runs through the opening or the recess. Here, the strut rests on a first support point and on a second support point of the flange section. The first support point and the second support point are distanced from each other.
    Such a side wall makes it possible for the spring element to be fixed to the strut that runs through the opening or the drain. Therefore, the stress resulting from the weight of the oscillating system supported by the spring element is no longer located at a single point, but is distributed by the strut between the support points.
    Therefore, the stress produced in the area of the spring element, that is, the force applied to the flange section, which is due to the weight of the oscillating system, is divided. Since the support points for the strut are spaced apart, there is a minimum distance between these two points. This has the consequence that the effort is divided or distributed between at least these two points. By such an arrangement, it is possible to prevent or at least minimize the deformation of the side wall of the frame. This is achieved in a particularly simple and economical way, since only a small piece in the form of the strut is needed that is stretched through the opening or emptying of the flange section. The arrangement of the strut extending through the opening or emptying reduces the respective force acting on the flange section at the first support point and at the second support point compared to the force caused by an oscillating system of the same weight , but acting on the flange section at only a single point.
    With such a side wall, aesthetic defects that would be visible to the user or customer can be avoided in the case of a household appliance that is not incorporated in a piece of furniture. You can also avoid loud noises that may arise in the case of a household appliance that is incorporated into a piece of furniture as a result of the collision of the side wall with a piece of furniture. Also, the vibrations of the side wall or side side of the frame are reduced or minimized. The thickness of the side wall can also be reduced. This reduces material costs and therefore makes the household appliance, in particular the washing machine or the washer-dryer, cheaper. Since the strut is simple and can be provided at low costs, cost optimization can also be achieved.

    Preferably, the strut forms a curvature disposed within the opening or inside the recess. By providing such a curvature or loop protruding towards the lower side of the flange section, the spring element can be fixed to the strut particularly particularly easily.
    The support points can be located on opposite sides of the opening or the recess to effectively divide the force acting on the support points.
    Preferably, at least one of the support points is formed as a projection protruding from the upper surface of the flange section. By providing such projections or promontories, which may have a distance from the edge of the opening or emptying, the support points may be particularly well defined. Likewise, such support points can be distanced from each other in a particularly simple manner. This brings about a particularly uniform distribution of the force applied to the flange section by the spring element, where the force results from the weight of the tank (and the drum disposed within the tank), which is supported by the spring element .
    Preferably, the flange section comprises at least one fixing element configured to hold the strut in place. Thus, it is easy to prevent the strut from moving relative to a wall portion of the flange section and the strut vibrating. Such fixing element can be provided in a particularly simple and economical way if it is formed as a flange that imprisons the strut.
    Preferably, the flange section has at least one hole in which a final section of the strut is inserted. In this way, a secure fixation of the strut to the flange section can be achieved.
    A final section of the strut can extend from a hole in the flange section along the bottom side of the flange section. By strutting the strut in the hole and causing the final section of the strut to pass along the lower side of the flange section, fixing the strut to the flange section is improved.
    Preferably, a final section of the strut rests on a leg of an "L" shaped element protruding from the bottom side of the flange section. Such an arrangement is particularly effective and simple when attaching the strut to the flange section of safe way.

    The "L" shaped element can be formed as a cut and folded part of the flange section. Thus, the "L" shaped element can be provided particularly easily.
    The strut may be formed as a wire, for example, a metal wire with a circular cross section. Alternatively, the strut may be formed as rolled metal with a rectangular cross section. As an example, a flat and curved piece of rolled metal can be used as a prop.
    The use of the same material for the side wall and the flange section, that is, a metal, is particularly effective for reinforcing the area of the flange section. In addition, the strut is particularly strong and robust if it is made of metal.
    However, the strut can also be formed as a wire made of plastic or as a flat element made of plastic. This provides particularly high flexibility by conferring the desired shape to the strut. This also reduces the weight of the strut compared to the strut made, for example, of metal wire or rolled metal.
    The frame according to the invention for a domestic apparatus for treating garments comprises a first side wall according to the invention and a second side wall according to the invention. The second side wall is arranged in front of the first side wall.
    The domestic apparatus for treating garments according to the invention has a frame according to the invention. Here, the vat of the domestic appliance is supported by at least one spring element fixed to the strut arranged next to the flange section of the first side wall and by at least one other spring element fixed to the strut arranged next to the flange section of The second side wall. The household appliance can be a washing machine and / or a clothes dryer. In other words, the household appliance can be, for example, a washing machine, as well as a dryer or a washer-dryer.
    The preferred advantages and embodiments described with respect to the side wall according to the invention are equally applicable to the frame according to the invention and to the domestic appliance according to the invention.

    Figure 1 schematically shows a household appliance 1 that can be configured as a washing machine, clothes dryer, or as a washer-dryer. He

    domestic appliance 1 comprises a frame 2 in which a bowl 3 is arranged. Inside the bowl 3 there is a drum 4, in which the clothes to be washed or dried are placed. The front door of the domestic appliance 1 is not shown. In addition, the domestic appliance 1 is shown without the cover that is usually closed by the frame 2 at its top.
    During operation of the domestic appliance 1, the rotational movement of the drum 4 inside the tank 3 causes an oscillating movement of the tank 3 inside the frame 2. In order to allow this movement, the tank 3 is connected to flange sections 5 , 6 or frame wings of a first side wall 7 and a second side wall 8 of the frame 2 by at least two springs 9, 10. In the example shown in Figure 1, the spring 9 is fixed to the flange section 5 of the first side wall 7, and the spring 10 is fixed to the flange section 6 of the second side wall 8, which is located in front of the first side wall 7. The flange sections 5, 6 or frame wings extend towards each other. The domestic appliance 1 may further comprise dampers 11 that are arranged between the tank 3 and the bottom wall 12 of the frame 2.
    In particular, if the tank 3 containing the drum 4 is connected to the flange section 5 or frame wing of the first side wall 7 by only a first spring 9 and to the flange section 6 or frame wing of the second side wall 8 by only a second spring 10, the force applied to the flange sections 5, 6 by the weight of the tank 3 and the oscillating movement of the tank 3 is considerable. This force can even cause the deformation of the flange sections 5, 6 and, as a consequence, the deformation of the side walls 7, 8.
    If the domestic appliance 1 is incorporated, collisions can occur between the side walls 7, 8 and a wall of the furniture in which the domestic appliance 1 is incorporated. If the domestic appliance 1 is not incorporated, the user of the domestic appliance 1 can observe the deformation of the side wall 7, 8. These problems are avoided by dividing the forces or forces applied by the springs 9, 10 to the flange sections 5, 6 as explained by referring to the following figures.
    In Figure 2, an example is shown that makes the division of force possible. The detailed representation of Figure 2 shows the fixing of the spring 9 to the frame wing or flange section 5. The at least one other spring 10 is preferably fixed to the opposite flange section 6 in the same way. The flange section 5 shown in Figure 2 comprises an opening 13 or through hole. A prop, which

    by way of example as a wire strut 14, it extends through this opening 13. The wire strut 14 further forms a curvature 15 protruding below a wall portion 16 of the flange section 5. The opening 13 it is arranged in this wall part 16. The spring 9 is fixed to the wire strut 14 by hanging a hook-shaped end section 17 of the spring 9 in the curvature 15 or loop formed by the wire strut 14.
    The wire strut 14 rests on a first support point 18 and on a second support point 19 adjacent to the opening 13 of the wall part 16. Also, the wire strut 14 is held in place by fasteners in shape of two tabs 20, 21. The tabs 20, 21 imprison the wire strut 14 between the wall part 16 and the lower sides of the tabs 20, 21. The force applied by the spring 9 is divided between the two points of support 18, 19. Therefore, the force is distributed over a large area compared to the flange section 5.
    This prevents deformation of the first side wall 7 and, similarly, of the second side wall 8.
    As can be seen particularly well from Fig. 3, the final sections 22, 23 of the wire strut 14 are inserted in holes 24, 25 provided in the wall portion 16 of the flange section 5. In the example shown in Figure 2, the support points 18, 19 extend from the opening 13 of the wall part 16 to these holes 24, 25. In the areas where the wire strut 14 is curved to make the end sections 22, 23 of the wire strut 14 penetrate the holes 24, 25, other fixing points are provided to fix the wire strut 14 to the wall part 16 of the flange section 5.
    Figure 4 shows a variant of the first flange section 5, where the other flange section 6 can be designed analogously. The wire strut 14 again forms a curvature 15. However, the bend 15 does not pass through the opening 13 of the wall portion 16 of the flange section 5, but the wire strut 14 is drawn through a recess 34 formed in the wall part 16.
    As shown in Figure 4, the recess 34 may be in the form of an essentially rectangular depression of the wall part 16, where the wire strut 14 rests on opposite limits of this depression. The curvature 15 is formed where the spring 9 pulls the wire strut 14 down into this depression or recess 34. In this variant, the support points are formed as protrusions 26, 27 protruding from the upper surface 28 of the part of wall 16. With these projections 26, 27 or headlands being provided, support points are provided
    5

    localized and well defined for wire strut 14. Since these projections 26,
    27 have a certain distance from the recess 34, the force applied by the spring 9 can be distributed particularly evenly over the length of the wall part 16.
    Figure 5 shows an alternative fixation of the final section 23 of the wire strut 14 to the wall part 16 in comparison to the variant shown in Figures 2 and 3. In the variant shown in Figure 5, the final section 23 is extends from a hole 29 of the wall part 16, which is furthest from the recess 34 than the projection 26. From this hole 29, the final section 23 extends first along the bottom side of the wall part 16 and it reaches another hole 30 provided in the wall part 16.
    An "L" shaped element 31 is disposed in the area of the other hole 30. The "L" shaped element 31 comprises a wing 32 extending perpendicularly from the bottom side of the wall part 16. From this wing 32, a leg 33 extends essentially parallel to the bottom side of the wall part 16. The final section 23 of the wire strut 14 rests on this leg 33. This fixing of the final sections 22, 23 to the wall part 16 of the flange section 5 it prevents particularly well that the wire strut 14 moves or vibrates. The "L" shaped element 31 may be formed by trimming and bending a piece of the wall portion 16 of the flange section 5.
    When the wire strut 14 and the promontories or projections 26, 27 or at least two recesses are introduced into which the final sections 22, 23 of the wire strut 14 are introduced, the force applied by the spring 9 as a consequence of the weight of the system Oscillating can be divided. Since the forces are divided into at least two points that have a minimum distance between them, it is possible to prevent the lateral sides or side walls 7, 8 of the frame 2 from becoming deformed.
    The strut that runs through the opening 13 or through the recess 34 can also be formed as rolled metal with a flat rectangular cross-section instead of the wire strut 14 (with an essentially circular cross-section), shown as example in the figures. The wire strut 14 can be made of metal. Also, a strut made of plastic can be used, which extends between opposite sides of the opening 13 or the recess 34.
