Definitions

  • the invention relates to a household appliance with a space delimited by appliance walls, in particular a dishwasher, with a washing area, a cover plate being arranged on an outer surface of at least one appliance wall leaving a gap.

  • the anti-drumming and / or sound insulation coating is or comprises, in turn, a reactively cured bituminous mixture.
  • the anti-drumming and / or soundproofing coating cannot have a constant thickness, but rather several non-contiguous areas with different thicknesses. The different areas can be obtained, for example, in that the mixture is sprayed on for different periods of time in the individual areas.
  • the device walls often have only a small thickness, for example for processing, shaping and / or cost reasons, so that noises arising in the room easily penetrate to the outside, which is undesirable.
  • an anti-drumming mat possibly attached on the outside of the outer surface of the respective device wall, for example a bitumen mat to prevent or at least dampen vibrations of the device wall that lead to droning noises
  • an acoustic insulating layer of one is preferably on the outside of the respective device wall, which is covered with a bitumen mat, for sound insulation Sound-absorbing and / or sound-reflecting material, for example made of an absorption fleece, is present over the entire surface.
  • the insulating layer with a relatively large thickness of, for example, 2 cm or more is often required, which then requires a correspondingly large installation space is no longer available for other purposes, for example to enlarge the washing compartment of a dishwasher.
  • the object of the invention is to propose a household appliance, in particular a dishwasher, of the type mentioned at the beginning with sound insulation that is improved in terms of its space requirement.
  • the acoustic sealing frame is preferably placed along the edge regions of the respective device wall and protrudes outwards with a predeterminable transverse distance from the outer surface of the device wall enclosed by it all around.
  • the cover plate is preferably attached, in particular placed, on the outside of the acoustic sealing frame in such a way that it covers the outer surface of the device wall enclosed all around by the acoustic sealing frame in a sound-insulating manner.
  • the acoustic sealing frame consists at least partially of an airborne sound absorbing and / or reflective sealing material.
  • the gap in the edge area of the cover plate can be perfectly acoustically isolated and a closed insulating sleeve made up of the combination of acoustic sealing frame and cover plate can be provided for the respective device wall, so that the passage of sound through the device wall can be sufficiently reduced.
  • the acoustic sealing frame is made of a sound-absorbing material or material, in particular elastically and / or plastically deformable material, preferably foam, absorbent fleece or felt, sound waves can be absorbed, i.e. swallowed, from the interior of the room enclosed by the device walls.
  • the acoustic sealing frame is, according to an advantageous development of the invention, in particular by a structural or surface element, in particular an acoustic and if necessary, an additional thermal insulation mat is formed, which has a breakthrough opening. This opening is closed by the cover plate.
  • the acoustic sealing frame preferably has a, in particular essentially rectangular, geometrical shape that encloses the opening all around and is in particular placed on an associated edge area of the respective device wall.
  • the acoustic sealing frame is expediently attached to the respective device wall in such a way that its opening comes to lie over any existing, three-dimensionally contoured, in particular uneven or outwardly protruding, outer surface of the device wall.
  • the cover plate is arranged over the opening with the three-dimensional shape, in particular uneven or outwardly protruding outer surface, of the device wall and preferably covers it from the outside forth on an edge region of the acoustic sealing frame around its opening in an overlapping manner.
  • the cover plate can in particular have a relatively small thickness, in particular a smaller layer thickness, than the material of the acoustic sealing frame. It can therefore be installed over the device wall on or in the acoustic sealing frame, closing its opening, where there is a smaller installation space available on the outside - in particular due to an outward curvature of the device wall - than in the other areas of the device wall, around predetermined To be able to comply with device dimensions. In a dishwasher, this is, for example, the central area of the top wall of the washing compartment, since the top wall is convexly curved outward for improved dripping behavior of liquid droplets sprayed onto it in the washing compartment of the washing compartment.
  • the cover plate can advantageously be designed to be essentially planar.
  • a specially manufactured molded part such as a pre-embossed absorption fleece, i.e. three-dimensionally shaped embossing fleece, is no longer required, which is placed over the entire outer surface of the respective device wall and its underside support contour is essentially complementary to the outer contour of the Appliance wall - in the case of a dishwasher, washing container wall - is formed, which makes its production complex and costly.
  • an acoustic insulation sleeve can now be provided for the respective device wall, largely independent of the spatial shape, in particular outward and / or inward elevations, of the respective device wall viewed perpendicular to its plane of position is, the noise reduction system according to the invention of acoustic sealing frame and cover plate, the mass production of household appliances, in particular dishwashers, is simplified. In particular, storage is simplified. Because now it is no longer necessary to keep in stock specifically three-dimensionally contoured molded sound insulation parts for different height profiles of device walls.
  • the noise reduction system comprising acoustic sealing frame and cover plate can ensure an at least approximately equally efficient or even improved sound insulation effect compared to a single, pre-embossed molded part that completely covers the respective device wall on the outside.
  • the cover plate is made in particular from a material which primarily effects airborne sound insulation, that is, a reflection of the airborne sound prevailing in the gap.
  • a material which primarily effects airborne sound insulation that is, a reflection of the airborne sound prevailing in the gap.
  • Such an essentially airborne sound-insulating material can in particular be made from fibers, preferably cotton, kenaf and / or synthetic fibers such as polyester fibers, or from embossed fleece or felt, cardboard and / or plastic and / or metal.
  • the material which can consist, for example, of fibers such as cotton, kenaf and / or synthetic fibers, for example polyester fibers, embossed fleece or felt, cardboard, and / or of a plastic material or metal that is not made up of fibers, but can optionally also be sound-absorbing, thus have sound-absorbing properties.
  • the cover plate is made of embossed fleece, in particular a flat embossed fleece mat, this variant saves material, is simpler to manufacture and cheaper in comparison to a contoured embossed fleece covering the entire outer surface of the respective device wall.
  • disruptive airborne sound is transmitted via a device wall into the mentioned gap, and / or airborne sound generated by vibrations of the respective device wall is transferred into the free space between the respective device wall and the cover plate arranged at a transverse distance from it, preferably approximately parallel to it, but at least partially reflected and / or absorbed there by the cover plate. Soundproof sealing of the gap in the edge area of the cover plate prevents the airborne sound from being able to propagate outward unhindered.
  • a primarily sound-absorbing material for example a foam or an absorption fleece such as a polyester and / or cotton fleece, comes into consideration as the sealing material for the acoustic sealing frame.
  • the sealing material can of course also have a sound-absorbing effect, with its acoustic sealing function possibly also being based solely on this property.
  • the gap width of the gap existing between the cover plate and a device wall can also be kept relatively small, for example only a few millimeters. Overall, the space requirement of the proposed sound insulation in a direction running transversely to the plane of the device wall can thus be reduced to only a few millimeters and thus the space available within the housing of the household device can be increased.
  • the sealing material which partially or completely forms the acoustic sealing frame which is for example a sound-absorbing foam or an absorption fleece such as a cotton and / or polyester fleece, is preferably elastically and / or plastically deformable. In this way, unevenness in a device wall, for example depressions or projections present therein, can be compensated for in an advantageous manner.
  • a design of the acoustic sealing frame that is exactly complementary to the spatial shape of the device wall in order to ensure an acoustically tight closure of the gap is not required.
  • Such a material can form an acoustic sealing frame as a whole or, for example, together with a stiffening material, for example a metal and / or a plastic.
  • a particularly space-saving arrangement is given in particular when the acoustic sealing frame is arranged at least partially within the gap.
  • the gap width of the gap can then be predetermined in a simple manner, preferably by the thickness of the acoustic sealing frame.
  • an anti-drumming layer in particular designed as a bitumen layer, is provided on the at least one device wall.
  • a heavy layer serves to dampen vibrations of the respective device wall, which are caused, for example, by a mechanical coupling of the device wall to a vibrating component, such as a motor, or, as is the case with a dishwasher, by water jets hitting the inside of the washing container wall .
  • a cover plate and an acoustic sealing frame assigned to it cover a device wall as largely as possible in order to ensure adequate soundproofing.
  • the acoustic sealing frame and the cover plate can be fixed to one another in a simple manner in terms of production technology, in particular mechanically fastened and / or glued to one another - for example by means of clamps.
  • a fixation, in particular mechanical fixation and / or adhesive bonding, can also be provided for the direct or indirect fixation of the acoustic sealing frame on a device wall.
  • an advantageous fastening of the acoustic sealing frame and cover plate can be achieved in that they are held in a form-fitting manner in a gap between a device wall and an outer housing wall of the household appliance that flanks this device wall. If the cover plate and acoustic sealing frame are of appropriate dimensions, they are held in a clamping manner in the gap space, so that, if necessary, the acoustic sealing frame can be glued to the device wall or to one there existing anti-drumming mat and a mutual gluing of acoustic sealing frame and cover plate can be dispensed with.
  • no separate cover plate is provided. Rather, this is formed by a housing wall, in particular an outer housing wall, of the household appliance.
