Definitions

  • the present invention relates to a refrigerator comprising a cabinet having defined therein a storage compartment and a crisp drawer supported on the bottom wall of the storage compartment, between such drawer and said bottom wall being interposed a sliding system.
  • refrigerator we mean any kind of refrigerating appliance in which a cabinet with a crisp drawer is defined, including refrigerators having a freezer and fresh food compartment, as well as side by side refrigerators.
  • the first sliding system used in the above kind of refrigerators was simply a sliding cooperation between the bottom wall of the crisp drawer and the bottom wall of the storage compartment.
  • This traditional system has the disadvantage of a side wobbling and annoying noise when the drawer is extracted and/or inserted in the storage compartment.
  • the combined effect of wobbling and noise gives to the user an impression of low quality, leaving aside any possible problems of preventing the user from extracting the crisp drawer in an easy and smooth way.
  • the rails are embedded in the bottom wall of the storage compartment by inserting them in slits provided is said bottom wall and by assuring that such rails have a root portion of sufficient dimensions in order to assure a proper fastening of the rails when insulating foam is injected in the space adjacent the liner of the cabinet.
  • the rails are fastened to the liner when the insulating foam is injected.
  • the crisp drawer presents raised shaped portions configured to cooperate with the rails, such shaped portions having preferably a lattice structure obtained by plastic injection molding.
  • a refrigerator 10 comprises a cabinet 12 with a door 14 and defining a fresh food storage compartment 16.
  • Such compartment 16 has a bottom wall 16a on which a crisp drawer 18 (known also as “crisper”) is supported.
  • the crisp drawer 18 is covered by a shelf 20 supported by side walls of the compartment 16.
  • the bottom wall 16a of the compartment 16 there are mounted two parallel rails 22 of polymeric material having a low coefficient of friction, for instance polyoxymethylene (POM), i.e. an engineer polymer widely used in the automotive and consumer electronic industry.
  • the rails 22 may be totally made of any low-friction material, or they may have a composite structure where only the top portion thereof is made of such material, while the base portion is made of less expensive polymer, for instance polypropylene (PP).
  • PP polypropylene
  • Figure 3 shows the left rail 22 and an overlapping crisper integrated ribbed structure 24 with side walls 24a defining a minimal side clearance (to hold the crisper 18 against wobbling).
  • Figure 4 shows the right rail 22 with an increased side clearance to cover the width dimensional and thermal variability.
  • each rail 22 may be fastened to the bottom wall 16a of the compartment 16 in several ways.
  • each rail 22 presents a root portion 22a which has a height similar or even higher than the dimension of the upper portion 22b which protrudes from the bottom wall 16a (in the example shown in figure 5 the root portion 22a has dimension similar to the upper portion 22b).
  • each rail 22 has a fixing enlarged portion 22c which cooperates in a snap engagement way with a corresponding slit 25 provided in the liner 26 defining the bottom wall 16a.
  • each rail 22 presents a flanged portion 22d which, after said insertion, abuts the liner 26 (the edge of the slit 25 is sandwiched between the enlarged portion 22c and the flange portion 22d of the rail 22.
  • an insulating foam F is injected in the area below the liner 26, it fastens the root portion 22a of the rail 22.
  • such solution has the advantage that the slit or cut out 25 is hidden by the flange portion 22d.
  • each hollow rail 22 does not have a root portion, rather a bottom enlarged portion 22f which abuts the liner 26 from the lower surface of the liner 26 (insertion from the bottom as shown by the arrow in figure 6 .
  • the advantage of this solution is that each rail 22 doesn't project into the insulating foam F and in case of cell wrapped pipe there's no obstruction for the pipe (almost flat surface from the foam side).
  • FIG 7 it is shown a detail of one of the integrated ribbed structures 24 provided on the bottom of the crisp drawer 18.
  • Such structures have a lattice construction with a plurality of crossing ribs 30 obtained during the injection molding process for producing the crisp drawer 18.
  • Such lattice structure has the advantage of creating a more rigid surface configured to slide on the rails 22.
  • Such lattice structure does not create molding defects in the bottom of the crisp drawer 18 which maintains a flat surface.
  • the sliding system according to the invention when the user is extracting the drawer 18 the side movement thereof is minimized by the interference assured by vertical side walls 24a cooperating with the rails 22, so that the sensorial experience and the perceived quality is very good (no strange noise and very low force requested for pulling out the drawer).
  • the robustness and behavior of the sliding system is comparable to much more expensive and complex system.
