Definitions

  • the invention relates to an insulation layer for application to a laundry drum for a drying device and a laundry drum for a drying device with such an insulation layer.
  • the laundry is circulated while supplying dry hot air in a rotating laundry drum. This is caused by a falling back of high-twisted laundry a laundry noise, which is subjectively perceived as disturbing. In particular, certain tonalities are perceived as subjectively disturbing.
  • the insulation layer is intended for application to a laundry drum for drying equipment and has at least one sound absorbing layer of a random copolymer having a saturated polymer backbone. Due to the insulating layer, a laundry drum can be noise-insulated with little effort and only insignificant increase in volume and weight.
  • a rubber of the M group (rubbers having a saturated polymethylene group) can be used as a random copolymer having a saturated polymer skeleton.
  • EPDM ethylene-propylene-diene rubber
  • EPM ethylene-propylene rubber
  • M group rubbers, and in particular EPDM are moisture resistant, ozone resistant, and highly heat resistant.
  • a rubber of the M group can also be very elastic and have a high chemical resistance.
  • Such copolymers are better processable compared to, for example, bitumen or rubbers of the R group, especially when cold processable.
  • the thickness of the sound-absorbing layer advantageously has at least 0.75 mm. With such thickness, significant noise reduction is still achieved without sacrificing manufacturing quality
  • the insulating layer may have a carrier layer which has a higher compliance than the noise-insulating layer, wherein the sound-absorbing layer is arranged on the carrier layer.
  • the comparatively stiff noise-insulating layer can also be applied to uneven, structured or embossed surfaces of the laundry drum without causing cracking in the sound-absorbing layer or larger free spaces between the laundry drum and the sound-absorbing layer.
  • the carrier layer then positioned between the drum surface and the sound-absorbing layer compensates for unevenness due to its deformation.
  • the insulating layer may comprise at least one heat-insulating layer.
  • the insulation layer may comprise at least one heat-insulating layer of polyethylene and / or polyurethane.
  • the insulating layer may comprise at least one layer of foam, which is formed as a heat-insulating support layer, so both assumes the function of the support layer and the heat-insulating layer. Because the pore structure is on the one hand well deformable, and also achieved by the air trapped in the pores good thermal insulation. By means of the layer of foam, the applicability of the insulating layer and its thermal insulation property can be greatly improved in a simple and inexpensive manner.
  • a thickness of the layer of foam is advantageously at least 1 mm.
  • the insulation layer may further be provided with an adhesive layer, in particular adhesive layer, for attachment to a surface of the laundry drum.
  • the adhesive layer may in turn be provided with a peelable protective film for protection against accidental sticking.
  • the protective film is peeled off.
  • the insulating layer may have a layer structure such that the peelable protective film is present at the bottom, the adhesive layer thereon, in turn the foam layer and, as the uppermost layer, the soundproofing layer.
  • the insulating layer accordingly has an adhesive layer on which the layer of foam is located, on which in turn is the sound-absorbing layer.
  • the laundry drum for drying equipment is at least partially occupied by such insulation layer. Since the random copolymers having a saturated polymer skeleton are comparatively stiff, it may even be possible to reduce the thickness of the drum wall when the insulating layer is applied.
  • an outer lateral surface of the laundry drum can be provided with at least one insulation layer.
  • the outer circumferential surface may be covered with at least two spaced apart at a predetermined distance strips of the insulating layer, wherein there is no insulating layer on the surface between the strips and this surface is provided as a contact surface for a drum belt. This prevents uncontrolled abrasion of the insulation layer during operation due to friction on the drum belt.
  • Fig. 1 shows a sectional side view of a sketch of a clothes dryer 1 with a laundry 2 filled with laundry drum 3.
  • the laundry is circulated by a rotation of the laundry drum 3 about its longitudinal axis L, resulting in a laundry noise.
  • a multi-layer insulation layer 5 is attached, as now described with reference to the enlarged section, which represents a section through the lateral surface 4.
  • the insulating layer 5 is first attached in a planar manner with an adhesive layer 7.
  • On the adhesive layer 7 is a thermally insulating and easily deformable PE foam layer 8 of thickness 2 mm as the lower layer of the insulating layer 5 on.
  • the foam layer 8 in turn, as the uppermost layer (upper partial layer of the insulating layer 5) is a sound-insulating layer 9 of EPDM of thickness 1 mm.
  • Fig. 2 shows the laundry drum 3 off Fig. 1 in an oblique view.
  • the outer surface 4 of the base material 6 is covered with at least two at a predetermined distance d (along the longitudinal axis) juxtaposed strips 10 of the insulating layer 5, wherein on the outer circumferential surface 4 between the strips 10 is no insulation layer 5 and this exposed area of Mantle surface 4 is provided as a contact surface 11 for a drum belt for rotary drive of the laundry drum 3.
  • the insulation layer can also be arranged on frontal surfaces or surface portions of the laundry drum.
  • the insulation layer may be disposed on an inside surface of the laundry drum.
  • the insulation layer likes also have more than two layers, z. B. a layer stack of several sets, each with a carrier layer and noise insulation layer.
  • two or more carrier layers and / or noise insulating layers may be stacked one above the other.
  • the insulation layer may be single-layered.
