Definitions

  • the invention relates to a domestic appliance, such as a washing machine, a tumble dryer, a dishwasher or the like, whose housing consists of a support frame formed from support beams, are attached to the formed as metal sheets side walls, and wherein means are provided for supporting the sound insulation between the carrier beam and metal sheet ,
  • the aforementioned housing structure is for example for laundry treatment machines or washing machines from the EP 0 943 721 A1 known. Since in this washing machine, the side walls have little bearing properties and therefore are built soft, their acoustic vibrations are hampered only to a small extent by the attachment to the base frame. When striking the walls by hand, therefore, creates a metallic sound that gives the user an impression of poor attachment and low stability. This can be prevented for example by the application of a bitumen mat.
  • the disadvantage of this solution is that bitumen mats for damping purposes are only produced in thicknesses from about 2 mm. Therefore, they can not be drawn into the outer edge of the side walls, which forms the contact point on the base frame. It thus lacks a positive position fixation of the mat.
  • bitumen mat must be glued consuming and very intense with the wall, as a self-loosening causes the mat falls into the device and any functional failures of other components causes. Bonding also creates a poorly recyclable composite of metal and bitumen.
  • the need to make an acoustic decoupling As a result, rattling noises are to be avoided.
  • the decoupling can be provided by the insertion of foam strips. However, these generate due to the thickness (3 mm) when pressing the wall to the frame a restoring force and complicate the assembly.
  • the invention thus raises the problem of improving the housing in a household appliance of the type mentioned in terms of noise insulation and / or the connection of the housing parts.
  • the achievable with the present invention consist in particular in that for the connection of the housing parts or between the housing parts in the investment areas an elastic material is used, which is formed as an elastic bead and can be applied by machine, wherein the application by means of a machine or Robot can be done.
  • an elastomer as an elastic material results in a sealing contact of the metallic parts, a so-called flexible bridge being created between these metallic parts, which achieves a noise effect with respect to noise and noise, which in particular prevents these noise developments.
  • gaps between the housing parts, in particular between the walls and the support bars are sealed or filled with elastic mass, whereby the leakage of noise from the interior of the housing, caused by pumps or other aggregates, is prevented.
  • the elastomer also has the advantage that it can first be applied in a fixing manner, wherein the bead can be fixed partially or completely circumferentially on the metal sheet at the edge or at the overlapping area prior to mounting the metal sheet formed as a wall.
  • the bead can be fixed partially or completely circumferentially on the metal sheet at the edge or at the overlapping area prior to mounting the metal sheet formed as a wall.
  • the caterpillar is fixed partially or completely circumferentially before mounting the metal sheet on the support bars of the support frame. After attachment of the caterpillar provided with the metal sheet to the support frame, the bead is deformed in its cross section, so that it forms a film-like shape within the gap at high contact pressure.
  • the determination of the bead can be done quickly and easily, as it is self-adhesive and with the application already on the device and also at the place where they should work, can be fixed.
  • the liability of the bead caused by the self-adhesive is expediently carried out only so strong that in the case of recycling, the bead can be removed easily and substantially completely from the metal sheet or from the frame.
  • the bead can also be applied in regions running parallel on the metal sheet or on the support beam, so that there is a much larger fixing surface or a widened noise insulation bridge.
  • the bead has sections of different cross sections, whereby different gap widths between metal sheet and carrier beam are reliably filled. In areas or sections in which a larger gap between sheet metal plate and carrier beam is formed, the bead has a larger section in sections.
  • the bead is formed such that at least partially a liquid-tight connection between the support beam and metal sheet is provided.
  • a high level of security against water damage is achieved by completely collecting the water flowing inside the housing walls in the bottom part, as a result of which a float switch arranged on the bottom part can switch on a safety device, for example a pump.
  • the bead can be used for liquid-tight connection between the housing walls and / or for sealing between housing cover and housing walls. By means of the elastic robbery gaps between the housing walls are reliably sealed, whereby the inside of the housing is protected by splash water from the outside.
  • Figure 1 shows in perspective a housing 1 for a household appliance, such as in the present case, a washing machine.
  • the housing comprises a bottom part 8, a rear wall 6, a cover 2 and a supporting frame 4 formed from support beams 3, wherein formed on the support frame 4 as sheet metal plates formed substantially vertical walls 5, and wherein in the overlapping region, better seen in the figure 2, of support beam 3 and metal sheet 5, and here between the support beam 3 and bottom part and metal sheet 5, means are provided for noise reduction.
  • the means provided for noise insulation consist of an elastomer, which is designed as an elastic bead 7.
  • the bead 7 before the assembly of the side panel 5 formed as sheet metal 5 at the edge or overlap region on the metal sheet 5 may be partially or completely circumferentially fixed, as shown in the embodiments of Figure 4 and Figure 6.
  • the housing 1 is shown in a partially transparent side view.
  • an upper substantially horizontal spar 3.1 and a front substantially vertical support beam 3.4 are shown, which together with the upward bending 3.3 of the bottom part 8 and a forward bending 3.2 of the rear wall 6 outlined in Fig. 1 support frame 4 form.
  • the circumferential bead 7 is fixed in the edge region on the metal sheet 5 formed as a side wall, so that the bead 7 rests on the support beams 3.1, 3.4 and the folds 3.3 and 3.2 after assembly of the metal sheet 5.
  • the application of the bead 7 can before the assembly of the metal sheet 5 on the support struts 3.1, 3.4 and the folds 3.3, 3.2 are fixed partially or completely circumferentially.
  • the fixation of the bead 7 can be done by means of a robot, and then easily and easily the metal sheet 5 can be attached and screwed or riveted. Due to the self-adhesion, the bead 7 remains in its intended position during the assembly process.
  • an elastic bead 7.4 is also arranged in the gap between the metal sheet 5.1 formed as a front wall and the frame part 3.4 or the front fold of the lateral metal sheet 5. This bead 7.4 additionally serves to seal the interior of the housing against external splash water.
  • FIG. 4 shows a metal sheet 5 formed as a side wall, which is provided on the inside with a completely circumferential bead 7.
  • the fixation of the bead 7 on the metal sheet. 5 is particularly advantageous to manufacture, since a machine for discharging the elastic material for the bead 7 only has to be moved in one plane. Since the bead 7 is fixed self-adhesive on the metal sheets 5, no special precautions need to be taken for the handling of the metal sheets 5 in the assembly process.
  • Fig. 5 is an expedient embodiment of the formed as a side wall metal sheet 5 is shown in which on the inside in addition to the fully circumferential bead 7, a further bead 7.1 is fixed. This can improve the impermeability to liquids at particularly stressed areas, for example in the lower area.
  • Fig. 6 a further embodiment of the formed as a side wall metal sheet 5 is shown, in which the arranged on the inside of the bead 7 is not performed completely encircling.
  • track sections 7.2 are fixed at points not stressed, whereby material for the bead 7, 7.2 is saved.
  • FIG. 7 an alternative embodiment of the formed as a side wall metal sheet 5 is shown, in which the arranged on the inside of the bead 7 is performed completely circumferential.
  • the rotating bead 7 is executed at thicker sites or at locations having a wider gap to the spar, with thicker sections 7.3 of the bead 7.
  • the embodiments proposed in FIGS. 4 to 7 are likewise applicable to the front wall 5.1 or rear wall 6 designed as a metal sheet.
