Definitions

  • the present invention relates to a cooling device, the structural alignment of which is improved.
  • an insulating material that is generally closed-cell rigid polyurethane, is filled between the liner and the outer case of the body in order to provide heat insulation between the inner volume and the outer environment.
  • One or more of the walls of the outer case, and preferably usually the back outer wall, can be made of a semi-rigid papery material, such as a cardboard, which provides light weight together with optimal insulation and acoustical properties.
  • the liner and the outer case of the body are placed in a mold and the insulating material, such as polyurethane, is injected as a liquid between them while in the mold, and over a short period of time expands to fill the space between liner and outer case. Due to the injection technic used to fill the intermediate volume between the liner and the outer case of the body, the liquid insulating material is not homogeneously distributed in such volume.
  • the body is usually demolded before the complete curing and cooling of the insulating material has occurred, so that the latter continues cooling after the body has been demolded.
  • the aim of the present invention is the realization of a cooling device comprising a body which structural alignment is increased.
  • the cooling device realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises at least the back wall of the outer case made of a papery material and having an outer surface on which a plurality of protrusions and/or recesses are provided, so as to increase the stiffness of the back wall and its resistance to possible deformations.
  • the protrusions/recesses are obtained by pressing the papery material board, in an easy and quick manner.
  • the protrusions/recesses are arranged substantially on the whole surface of the back wall, so as to increase the mechanical resistance of the whole back wall.
  • the protrusions/recesses extends along vertical parallel directions, horizontal parallel directions or both defining closed shapes on the outer surface of the back wall.
  • the back wall comprises a raised central plateau wherein the thickness of the back wall is advantageously increased and which can be obtained by means of blow molding.
  • the thickness increase of the back wall on the central plateau is comprised between 5 mm and 25 mm and preferably it is comprised between 10 mm and 20 mm.
  • the protrusions/recesses have a thickness and/or a depth which is substantially equivalent to half the thickness of the central plateau.
  • the cooling device of the invention is a refrigerator and in particular it is a double door refrigerator, while according to a further embodiment it is a multi-door refrigerator.
  • Figure 1 – is a front perspective view of a cooling device according to the invention with the door removed, i.e. of the body of the cooling device.
  • Figure 2 — is a cross-sectional view of the body of Figure 1, taken along the vertical longitudinal median plane.
  • Figure 3 – is a rear perspective views from below of the body of Figure 1 according to an embodiment.
  • Figure 4 – is a rear perspective views from below of the back wall of the outer case of the body of Figure 3.
  • Figure 5 — is a rear view of the back wall of Figure 4.
  • Figures 6 and 7 – are respectively a cross-sectional view of the back wall of Figure 4 taken along line VI-VI of Figure 5 and an enlarged detail of it.
  • Figures 8 and 9 – are respectively a cross-sectional view of the back wall of Figure 4 taken along line VIII-VIII of Figure 6 and an enlarged detail of it.
  • Figures 10 and 11 – are rear perspective views from below of the body of Figure 1 according to two further embodiments.
  • the cooling device 1 comprises a body 2 that has a liner 3 and an outer case 4 comprising a back wall 5 made of a semi-rigid papery material such as a paperboard or a cardboard.
  • the liner 3 and the outer case 4 define between them an intermediate volume 6 filled with an insulation material 7, such as for instance polyurethane foam.
  • the back wall 5 of the outer case 4 has an outer surface 8 and it comprises a plurality of protrusions 9 and/or recesses 10 arranged on the outer surface 8.
  • the protrusions 9 and/or the recesses 10 increase the stiffness of the back wall 5, which therefore does not deform due to the transformations of the insulation material placed in the intermediate volume 6 during the production process of the body 2 of the cooling device 1. This ensures a better structural alignment of the body 2, so that no additional working phases, like a re-alignment phase, are required during the production of the body 2, thus diminishing the production time and cost.
  • the outer case 4 may comprise also further walls, such as for instance the lateral walls, made of a papery material and provided with protrusions 9 and/or recesses 10 according to the present invention, without departing from the scope of protection of the present invention.
  • both protrusions 9 and recesses 10 are provided on the outer surface 8 of the back wall 5.
  • the protrusions 9 and/or recesses 10 provided on the back wall 5 contribute also to improve the acoustical properties of the body 2 of the cooling device 1, diminishing the vibrations and hence the noise produced by the cooling device 1.
  • the protrusions 9 and/or recesses 10 are obtained on the outer surface 8 of the back wall 5 by pressing. This allows to easily obtain a back wall 5 with variable thickness, thus defining the desired protrusions 9 and/or recesses 10 on its outer surface 8.
  • the protrusions 9 and/or the recesses 10 are arranged substantially on the whole outer surface 8 of the back wall 5. More clearly the protrusions 9 and/or recesses 10 are arranged on a portion of the outer surface 8 equivalent at least to the 75% of the whole outer surface 8.
  • the protrusions 9 and/or recesses 10 preferably extend along a portion of the height of the outer surface 8 equivalent at least to the 75% of the whole height of the outer surface 8 and along a portion of the width of the outer surface 8 equivalent at least to the 75% of the whole width of the outer surface 8, as illustrated in the attached Figures 3, 10 and 11.
  • the protrusions 9 and/or recesses 10 extend parallel to each other along vertical directions, as illustrated in particular in Figure 11 and also in Figure 3.
  • the protrusions 9 and/or recesses 10 extend vertically on the outer surface 8 substantially for the whole height of the outer surface 8, i.e. at least for 75% of the whole height of the outer surface 8.
  • the back wall 5 is provided only with protrusions 9 and/or recesses 10 that extend vertically parallel to each other and spaced apart from each other.
  • the protrusions 9 and/or recesses 10 extend parallel to each other along horizontal directions, as illustrated in particular in Figure 10 and also in Figure 3.
  • the protrusions 9 and/or recesses 10 extend horizontally on the outer surface 8 substantially for the whole width of the outer surface 8, i.e. at least for 75% of the whole width of the outer surface 8.
  • the back wall 5 is provided only with protrusions 9 and/or recesses 10 that extend horizontally parallel to each other and spaced apart from each other.
  • the protrusions 9 and/or recesses 10 define a plurality of closed shapes on the outer surface 8 of the back wall 5, as illustrated in Figure 3.
  • the back wall 5 is provided with protrusions 9 and/or recesses 10 defining a plurality of concentric closed shapes, spaced apart from one another.
  • the back wall 5 comprises a raised central plateau 11 and the protrusions 9 and/or recesses 10 are provided on the outer surface 8 of the back wall 5 on the raised central plateau 11.
  • the thickness of the back wall 5 is increased on the central plateau 11.
  • the thickness increase of the back wall 5 on the central plateau 11 is comprised between 5 mm and 25 mm, and preferably is comprised between 10 mm and 20 mm.
  • the presence of the central plateau 11 having in particular an increased thickness contributes to improve the stiffness of the back wall 5.
  • the protrusions 9 and/or recesses 10 have a thickness and/or a depth substantially equivalent to half of the thickness of the central plateau 11. This ensures that optimal mechanical characteristics are conferred to every part of the back wall 5, without having portions of the back wall 5 having too little thickness that could result in a weakening of the back wall 5 while at the same time not increasing excessively the amount of space occupied by the body 2.
  • the raised central plateau 11 is obtained on the outer surface 8 of the back wall 5 by means of blow molding.
  • the cooling device 1 above described is a refrigerator.
  • the cooling device 1 above described is a double door refrigerator and in a further embodiment it is a multi-door refrigerator.
  • having a back wall 5 with mechanical characteristics that avoid possible deformations of the back wall 5 itself and, consequently, of the body 2 is particularly important in case of double or multi door refrigerators where misalignments on the body 2 would result immediately apparent due to a poor matching of the doors on the front of the refrigerators, thus diminishing the user satisfaction and possibly affecting the overall cooling performances of the refrigerator.
