Definitions

  • the present invention relates to a domestic appliance, particularly clothes dryer, a washing machine or a dishwashing machine, comprising a cabinet and a treatment chamber within such cabinet.
  • insulation panels have been used in connection with internal surfaces of the cabinet or external surfaces of the treatment chamber, for instance the washing tub of a dishwasher.
  • Such panels comprise one or more sound absorbing layers which are not stiff, for instance of porous media.
  • Such specific sound absorption structure is the one generally disclosed for instance by JP2002029330 , even if with certain modifications for the specific use in domestic appliances.
  • Such structure presents a plurality of protruding parts shaped as hollow "cubes" defined between a flat base part and a hollow protruded part both made of rubber or thermoplastic material and preferably obtained through a blow-molding process.
  • Such sound absorption structure is sufficiently stiff to be self-carrying in order to be mounted in the lower portion of the cabinet of the appliance, for preventing noise leakage from the appliance in the bottom area thereof.
  • the structure is used for collecting possible water leaking from the washing chamber.
  • the structure is preferably shaped with an inverted pyramid shape and is provided with sensor for detecting a certain level of water in order to block water supply (through devices known with the names of water-stop or aqua-stop).
  • a dryer or a washing machine 10 comprises a cabinet 12 with side walls 12a, a front wall 12b and a top wall 12c.
  • the front wall 12b comprises a door 14 for accessing a washing chamber (not shown).
  • a sound absorbing flat structure 16 having dimensions corresponding to the horizontal cross section of the cabinet.
  • Such structure 16 ( figures 2 and 3 ) is formed by a damping material, for instance rubber-elastic material or thermoplastic material, and comprises a bottom flat layer 16a and an upper layer 16b having protrusion 18 of different dimensions which are capable of damping different noise frequency according to such dimensions.
  • the thickness of bottom layer 16a may be preferably comprised between 0,5 and 4 mm, while the thickness of upper layer 16b may be preferably comprised between 0,3 and 3 mm.
  • the material of both layers 16a and 16b is preferably an olefin copolymer, preferably a random ethylene-propylene (EPM) copolymer which is flexible and it is used commercially as elastomer.
  • EPM ethylene-propylene
  • Other materials can be used as well, for instance vulcanizable terpolymers which are obtained when a small amount of a tetrafunctional monomer, such as dicyclopentadiene, is copolymerized with ethylene and propylene (EPDM elastomers).
  • the way in which the structure 16 is fixed to the appliance is not critical, and it may be similar or identical to the fastening system presently used for fixing the aqua-stop tray which prevents possible flooding.
  • one of the advantages of the present invention is related to the double use of the structure, i.e. to reduce noise emission and to be used as the tray for the water sensor of the aqua-stop system.
  • This solution is shown in figures 4 and 5 , where the structure 16 is shaped as an inverted frustum of pyramid, with inclined walls 18 and a sink central portion 20 where a float 22 is placed for detecting any water leakage and to send a corresponding signal to a central unit.
